Automatic feeding device for pets

Technical Field

The invention relates to the technical field of pet supplies, in particular to an automatic feeding device for pets.

Background

The pet food is divided into wet food and dry food, and if the pet food is eaten for a long time, the water intake of the pet is too small, and the serious pet food can cause urinary system and other related diseases of the pet. The edible wet food can not only provide more comprehensive nutrition for the pet, but also ensure sufficient water intake, and is more beneficial to the health of the pet. However, wet food cans are perishable after opening and pets need to eat multiple times within a day.

At present, automatic feeding equipment designed for feeding pet food is not available in the market, and wet food mainly adopts a manual feeding mode. However, the time and labor are wasted when the food is eaten manually, so that the food accounts for a lower proportion in actual eating.

Embodiment 1 this embodiment provides an automatic edible device structure of throwing of pet, as shown in fig. 1, fig. 2, connect 1,extrusion support 2, rotatingelectrical machines 6 and link mechanism including backup pad, silica gel, wherein,extrusion support 2 is equipped with ahorizontal trompil 21 including horizontal support body and the vertical support body of the vertical connection of one end with horizontal support body on the horizontal support body. Thesilica gel joint 1 is a sleeve body made of silica gel materials, aninner cavity 101 is arranged in the silica gel joint, and the whole silica gel can be deformed. The upper end that silica gel connects 1 is equipped withinner chamber 101 intercommunication and feedinlet 11 up, and the lower extreme that silica gel connects 1 is equipped withinner chamber 101 intercommunication andextrusion mouth 12 down.

A support plate (not shown) is disposed in parallel with the horizontal shelf, above the horizontal shelf, and a discharge port of the packingbag 100 containing wet pet food is downwardly fixed to the support plate, as shown in fig. 3 and 4. Specifically, a tube body with a clamping groove structure on the outer wall can be formed at the bottom of thepackaging bag 100, and the clamping groove and the supporting plate are clamped and matched when the packaging bag is used.

The upper end of thesilica gel joint 1, i.e. thefeed inlet 11, is used for communicating with the discharge outlet of thepackaging bag 100 and can make thefeed inlet 11 and the discharge outlet be in threaded connection for convenient use, and of course, in this embodiment, thefeed inlet 11 is sleeved outside the discharge outlet. The lower end of thesilicone rubber joint 1 is designed to be a closing-in structure (i.e. the closing-inend 102 in the figure), and the closing-in structure refers to a structure that is contracted from a cylindrical shape to a flat-shaped opening as shown in fig. 5. Because the lower end opening of thesilica gel joint 1 is smaller than the upper end opening, after thesilica gel joint 1 is extruded, theinner cavity 101 of the silica gel joint can generate air pressure difference with the outside and thepackaging bag 100, and then wet pet food in thepackaging bag 100 is sucked downwards from thepackaging bag 100 by utilizing the negative pressure condition of theinner cavity 101 which is smaller than the outside and the atmospheric pressure of thepackaging bag 100.

As shown in fig. 1, in the present embodiment, thesilicone joint 1 is formed by joining upper, middle and lower annular bodies arranged in sequence along the axial direction from top to bottom, and the sizes of the three annular bodies are reduced in sequence, so that the silicone joint 1 can adopt an integrally formed multi-layer structure for facilitating processing and improving the sealing performance of thesilicone joint 1. The number of the layers of the silica gel joint 1 can be increased to 4~5 layers according to actual needs, and the height of each layer can be slightly reduced. The multi-layer structure silica gel joint 1 structure used in this embodiment can be conveniently pressed from the axial alignment of the silica gel joint 1 to laminate the silica gel joint 1 layer by layer, and can generate a large volume change in theinner cavity 101 of the silica gel joint 1 with a simple movement track and a small acting force, so that an air pressure difference is generated between theinner cavity 101 and the outside and between the packingbag 100.

Based on the above, the lower end of thesilicone rubber joint 1 is disposed in thehorizontal opening 21 of the extrudingbracket 2, and the opening diameter of thehorizontal opening 21 is preferably adapted to the receivingend 102 of the silicone rubber joint 1 or the lowermost ring body. Theextrusion support 2 is driven to reciprocate in the axial direction of the silica gel joint 1 through the matching action of therotating motor 6 and the link mechanism, so that the silica gel joint 1 can be controlled to be switched between a deformation state and a non-deformation state, theinner cavity 101 generates negative pressure to suck wet grains into theinner cavity 101 when thesilica gel joint 1 deforms, and then when theextrusion support 2 loosens thesilica gel joint 1, theinner cavity 101 can be recovered, and the wet grains are downwards discharged through theextrusion port 12 and thehorizontal opening 21.

In this embodiment, the link mechanism includes afirst link 5 having a short length and asecond link 4 having a long length, one end of thefirst link 5 is hinged to the output shaft of therotating motor 6, and the other end of thefirst link 5 is hinged and fixed to one end of thesecond link 4 without being suspended by a support. The other end of the second connectingrod 4 is hinged and fixed with the vertical side wall of the vertical frame body of theextrusion support 2. Through the structure, the rotating motor 6 rotates to drive the other end of the connecting rod I5 to eccentrically rotate relative to the output shaft of the rotating motor 6, so that the other end of the connecting rod II 4 is driven to move up and down, and further the vertical frame body and the horizontal frame body are driven to move up and down, and as the silica gel joint 1 is fixed on the packaging bag 100, the horizontal opening 21 is in clearance fit with the closing-in end or the lower end of the silica gel joint 1 at first when the horizontal frame body moves up; the horizontal frame body continues to move upwards, the horizontal opening 21 is in interference fit with the middle part or the lower end of the silica gel joint 1, then the silica gel joint 1 is driven to carry out lamination deformation in the continuous upward movement process, the gas in the inner cavity 101 is discharged from the extrusion port 12, and the inner cavity 101 generates negative pressure; then the horizontal support body moves downwards, in the process, the inner cavity 101 of the silica gel joint 1 is increased, but the two caliber of the extrusion opening 12 adopting the closing-up design is smaller, so the inner cavity 101 sucks wet grains from the packaging bag 100 until the horizontal support body is in clearance fit with the silica gel joint 1 again, and after the silica gel joint 1 is loosened, the wet grains are discharged downwards from the extrusion opening 12.

As apparent from the above description, the present embodiment provides an automatic feeding device that can automatically take out wet food from the packingbag 100 containing wet food for feeding.

The rack and pinion mechanism may also be provided without a guide assembly.

Alternatively, the link mechanism can be replaced by a worm gear transmission mechanism, the structure of which is similar to that of a gear-rack mechanism, and the difference is that a gear and a rack are replaced by a worm and a worm wheel respectively.
