Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a cat bar extrusion linkage mechanism. Background Technology

[0002] Currently, feeding pets pasty foods (such as cat treats) usually requires manually tearing open the packaging and squeezing the food. To improve convenience and hygiene, some auxiliary squeezing devices have appeared on the market. These devices mechanically squeeze the food from soft packaging into the food bowl, avoiding direct contact between human hands and the food, and aiming to make the feeding process more convenient.

[0003] However, in terms of compression effect, most existing devices of this kind use simple push rod or roller structure, resulting in unstable compression stroke and insufficient end pressure, which can easily lead to food residue inside the packaging and waste.

[0004] Secondly, in terms of cleaning and maintenance, due to the lack of an effective self-cleaning design, the extruded viscous food is prone to splashing or adhering to the inner wall of the device. After long-term accumulation, it is easy to breed bacteria and produce odors, and cleaning is extremely inconvenient.

[0005] To address the above issues, we have introduced a cat bar extrusion linkage mechanism. Utility Model Content

[0006] This utility model discloses a cat bar extrusion linkage mechanism, which aims to solve the technical problems in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A cat food extrusion linkage mechanism includes a base, a lower housing on the base, an upper housing detachably connected to the lower housing, and a pressing mechanism for compacting cat food, a shearing mechanism for cutting cat food, and a clamping mechanism for gripping and conveying cat food are sequentially arranged between the upper housing and the lower housing. The pressing mechanism includes an upper pressing plate and a fixed frame. An upper pressing rubber plate is fixedly connected to the bottom of the upper pressing plate, and a screw sleeve is fixedly connected to the upper pressing plate. The fixed frame is connected to the upper housing by screws. A drive source is installed on the fixed frame, and a lead screw is provided at the output end of the drive source. The lead screw extends into the interior of the screw sleeve and is threadedly connected to it. A secondary pressure plate is fixedly connected to the upper pressure plate, and a scraper is fixedly connected to one side of the secondary pressure plate. The bottom of the secondary pressure plate and the scraper are higher than the bottom of the upper pressure plate.

[0008] In a preferred embodiment, a lower fixing plate is fixedly connected inside the lower housing, and a gap for placing the cat strip is formed between the upper pressure plate and the lower fixing plate.

[0009] In a preferred embodiment, a battery for supplying power to each drive component is further disposed between the upper housing and the lower housing.

[0010] In a preferred embodiment, the lower housing has an inlet for cat food to enter.

[0011] In a preferred embodiment, a workstation for placing a food container is provided on the base below the feed inlet.

[0012] The cat bar extrusion linkage mechanism provided by this utility model has the following advantages: The feeding mechanism proposed in this invention employs linear extrusion driven by a lead screw and nut, which, together with a lower fixed plate, forms a stable support, ensuring that the contents are completely extruded. Simultaneously, a scraper integrated into the pressure plate automatically cleans the inner wall of the casing during the extrusion return stroke, effectively preventing food residue and hygiene issues. This invention balances automation efficiency, cleaning reliability, and ease of use, significantly improving the pet feeding experience. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] This utility model discloses a cat bar extrusion linkage mechanism.

[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a cat food extrusion linkage mechanism includes a base 1, a lower housing 2 on the base 1, an upper housing 3 detachably connected to the lower housing 2, and a pressing mechanism 4 for compacting cat food, a shearing mechanism 5 for cutting cat food, and a clamping mechanism 6 for clamping and conveying cat food are arranged sequentially between the upper housing 3 and the lower housing 2. The pressing mechanism 4 includes an upper pressing plate 41 and a fixed frame 43. An upper pressing rubber plate 45 is fixedly connected to the bottom of the upper pressing plate 41. A screw sleeve 42 is fixedly connected to the upper pressing plate 41. The fixed frame 43 is connected to the upper housing 3 by screws. A drive source 44 is installed on the fixed frame 43. A lead screw is provided at the output end of the drive source 44. The lead screw extends into the inside of the screw sleeve 42 and is threadedly connected to it. A secondary pressure plate 47 is fixedly connected to the upper pressure plate 41, and a scraper 48 is fixedly connected to one side of the secondary pressure plate 47. The bottom of the secondary pressure plate 47 and the scraper 48 are higher than the bottom of the upper pressure plate 45. In this embodiment, the working principle of the pressing mechanism 4 is to achieve stable compression and simultaneous cleaning of the cat bar. During operation, the drive source 44 is activated, and the lead screw at its output end rotates. Since the screw sleeve 42 is fixed to the upper pressure plate 41, and the lead screw and the screw sleeve 42 form a threaded pair, the rotational motion is converted into a precise linear descent of the upper pressure plate 41 along with the upper pressure rubber plate 45 at its bottom. The upper pressure rubber plate 45 then compresses the cat bar portion placed below it, pushing out the contents.

[0022] At the same time, as the upper pressure plate 41 descends as a whole, the secondary pressure plate 47 and scraper 48 fixed on it also descend synchronously. Since the bottom of the scraper 48 is higher than the bottom of the upper pressure plate 45 and the side of the scraper 48 is close to the inner wall of the housing, when the upper pressure plate 45 completes the extrusion and moves upward to reset, the scraper 48 can scrape off any sticky food that may splash or remain on the inner wall of the housing, preventing it from accumulating and hardening, which would affect hygiene and the normal operation of subsequent mechanisms, thus realizing the linkage between extrusion and self-cleaning.

[0023] The drive source 44 can be a motor or an entire drive unit equipped with a reduction gear.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a lower fixing plate 46 is fixedly connected inside the lower housing 2, and a gap for placing the cat strip is formed between the upper pressure plate 45 and the lower fixing plate 46. In this embodiment, the working principle of the lower fixing plate 46 is to provide a stable and reliable bearing platform and extrusion reference surface for the cat bar. The gap formed between it and the upper pressure plate 45 constitutes the precise placement and positioning space for the tail of the cat bar.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a battery 7 for supplying power to each drive component is also provided between the upper housing 3 and the lower housing 2; In this embodiment, the battery 7 serves as a built-in independent power source, and its working principle is to provide the required electrical energy to all driving components of the pressing mechanism 4, the shearing mechanism 5, and the clamping mechanism 6.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, the lower housing 2 is provided with an inlet 8 for cat food to enter; In this embodiment: The feed port 8 serves as the guide channel for the cat bar, and its working principle is to guide the cat bar into the mechanism in the correct direction and position. The user or an auxiliary guiding device can push the cat bar into the feed port 8 so that its tail accurately reaches the clamping position of the clamping mechanism 6.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, a workstation for placing a food container 9 is provided on the base 1 below the feed inlet 8; In this embodiment, the station for placing the food bowl 9 is pre-designed to be directly below the outlet of the extruded cat sticks.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
