Description

Technical Field

[0001] The utility model relates to the technical field of pet feed processing, in particular to a fixing mouth mechanism for pet feed filling. Background Art

[0002] In the pet food industry, feed filling is a crucial step, directly related to product quality and production efficiency. Currently, a widely used pet food filling method in the market relies on a traditional robotic arm combined with a simple filling head.

[0003] The Chinese patent with announcement number CN214397306U discloses a bagged feed filling device, including a support column, a support plate, a support rod, a material receiving bin, a hydraulic press, a dosing component, an opening, a blanking component and a bag-supporting device. The support plate is connected to the middle position of the support column, the support rod is symmetrically arranged at the end of the support column, the material receiving bin is connected to the support rod, the hydraulic press is arranged on the support plate, the dosing component is arranged on the hydraulic press and is movably arranged in the material receiving bin, the opening is arranged on the bottom plate and on both sides of the hydraulic press, the blanking component is arranged on the bottom plate and at the opening, and the bag-supporting device is arranged at the lower end of the inner side wall of the support column and under the support plate.

[0004] As mentioned in the above application, the existing feed filling mechanism has an unadjustable feed outlet height, which means it cannot be used for packaging bags of different sizes. In addition, it lacks a fixing mechanism, which cannot ensure the stability of the connection between the packaging bag and the feed outlet during the filling process. Utility Model Content

[0005] The purpose of the utility model is to overcome the problems in the prior art, that is, the height of the feed opening of the existing feed filling mechanism is not adjustable, that is, it cannot be applied to packaging bags of different sizes, and secondly, there is a lack of a fixing mouth mechanism, which cannot ensure the stability of the connection between the packaging bag and the feed opening during the filling process. The utility model provides a fixing mouth mechanism for pet food filling, which is connected between the upper annular seat and the lower annular seat through a telescopic feed pipe. That is, by controlling the telescopic feed pipe to be extended and retracted, the height of the lower annular seat can be adjusted. When in use, the telescopic feed pipe is controlled to be extended and retracted by controlling the hydraulic telescopic rod to be extended and retracted. The height of the discharge port can be adjusted so that the discharge port can be suitable for packaging bags of different sizes. That is, after packaging bags of different sizes are connected to the discharge port, their bottoms can be in contact with the placement table, so that the weight of the packaging bag will not be applied to the discharge port, thereby improving the stability of the connection between the discharge port and the packaging bag. Secondly, when in use, the packaging bag to be filled is placed on the discharge port, and the preset connecting rope on the packaging bag is hung on the hook to complete the fixation of the packaging bag. Then, the Z-shaped connecting frame is pushed to move, and the Z-shaped connecting frame moves, which drives the gear ring to move, and the gear ring moves to drive the gear plate to rotate. The gear plate rotates and drives the fixed block to rotate. The fixed block rotates and drives several hooks to expand or contract, thereby adjusting the opening of the packaging bag fixed on the hook, and realizing the expansion of packaging bags of different sizes. The packaging bags are opened and the filling stability is improved. After the filling is completed, the several hooks can be controlled to contract to separate the packaging bag from the hook.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The utility model discloses a fixing mouth mechanism for filling pet feed, which is used to be connected at the outlet of a filling hopper, and comprises an upper annular seat, a telescopic discharge tube and a lower annular seat. The telescopic discharge tube is conductively connected between the upper annular seat and the lower annular seat. A discharge mouth is integrally formed on the lower surface of the lower annular seat. The height of the discharge mouth is adjusted by adjusting the length of the telescopic discharge tube. A fixing mouth mechanism is also provided on the lower annular seat, which is used to limit and fix a feed packaging bag sleeved on the discharge mouth.

[0008] Preferably, the fixing mechanism includes a fixed block, a fixed shaft welded at one end of the fixed block along the length direction, and the fixed shaft is rotatably connected to the lower annular seat, the other end of the fixed block extends to the outside of the lower annular seat, and a hook is provided on the lower surface of the other end of the fixed block, a gear plate is welded on the fixed shaft above the fixed block, a gear ring is slidably connected to the upper surface of the lower annular seat, and the gear ring is meshed with the gear plate.

[0009] Preferably, a plurality of the fixing mouth mechanisms are provided, and the fixing mouth mechanisms are distributed in a ring shape, and the intervals between two adjacent fixing mouth mechanisms are equal.

[0010] Preferably, a positioning mechanism is provided on the outer wall of the upper annular seat, and the positioning mechanism is used to limit and fix the gear ring;

[0011] The positioning mechanism includes a positioning ring and a Z-shaped connecting frame. Two arc-shaped holes are symmetrically provided on the upper surface of the positioning ring. The bottom end of the Z-shaped connecting frame is welded and fixed to the gear ring. The top end of the Z-shaped connecting frame extends to the top of the positioning ring through the arc-shaped hole. The top end of the Z-shaped connecting frame is located on the upper and lower sides of the positioning ring and is threadedly connected to the limiting nuts. The top end of the Z-shaped connecting frame is provided with an external thread for use with the limiting nuts.

[0012] Preferably, the hook is a U-shaped structure, one end of which is welded and fixed to the fixed block, and the other end is a pointed structure.

[0013] Preferably, several hydraulic telescopic rods are fixed between the upper annular seat and the lower annular seat, and several hydraulic telescopic rods are located on the outside of the telescopic discharge pipe. Several hydraulic telescopic rods are distributed in a ring, and the spacing between adjacent hydraulic telescopic rods is equal. By controlling the extension and contraction of the hydraulic telescopic rods, the height adjustment of the discharge port is achieved.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This pet food filling fixing mechanism is connected between the upper and lower annular seats via a telescopic discharge pipe. By controlling the extension and retraction of the discharge pipe, the height of the lower annular seat can be adjusted. During use, the telescopic discharge pipe is controlled by controlling the extension and retraction of the hydraulic telescopic rod. This allows the discharge opening to be adjusted in height so that it can accommodate packaging bags of different sizes. This means that after packaging bags of different sizes are connected to the discharge opening, their bottoms can all contact the placement surface, preventing the weight of the bags from being applied to the discharge opening, thereby improving the stability of the connection between the discharge opening and the packaging bags.

[0016] Secondly, when in use, the packaging bag to be filled is placed on the discharge port, and the preset connecting rope on the packaging bag is hung on the hook to complete the fixation of the packaging bag. Then, the Z-shaped connecting frame is pushed to move, and the Z-shaped connecting frame moves to drive the gear ring to move. The gear ring movement drives the gear plate to rotate, and the gear plate rotation drives the fixed block to rotate. The fixed block rotates to drive several hooks to expand or contract, thereby adjusting the opening of the packaging bag fixed on the hook, and realizing the expansion of packaging bags of different sizes, thereby improving the stability of filling. After the filling is completed, the several hooks can be controlled to contract to separate the packaging bag from the hook. BRIEF DESCRIPTION OF THE DRAWINGS
