Description

Technical Field

[0001] This utility model relates to the field of pet snack production technology, and in particular to a pet snack filling auxiliary fixing device. Background Technology

[0002] Pet snacks are supplementary foods specially designed for pets (such as cats and dogs), featuring diverse flavors, nutritional supplements, and interactive rewards.

[0003] In the production process of pet snacks, filling is a crucial step in packing the snacks into the packaging container. With the development of the pet food market, more and more flexible packaging materials, such as soft plastic bags and aluminum foil bags, are being used for pet snack packaging. These packaging materials have advantages such as low cost and good sealing performance. However, during the filling process, the soft texture of flexible packaging materials makes them prone to wrinkling, deformation, or tipping due to the impact of the material, resulting in inaccurate filling position and material spillage, which affects the packaging quality and production efficiency of the product. Therefore, it is necessary to design a pet snack filling auxiliary fixing device to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary fixing device for filling pet snacks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pet snack filling auxiliary fixing device includes a base, a conveying device fixedly installed on the upper surface of the base, a support frame fixedly installed on the back of the base, a connecting frame fixedly connected to the inner bottom wall of the support frame via a lifting mechanism, a bidirectional screw rotatably installed inside the connecting frame, a motor connected to the bidirectional screw fixedly installed on the outer wall of the connecting frame, two moving blocks threadedly installed on the outer wall of the bidirectional screw via a limiting mechanism, clamping plates fixedly connected to the upper surfaces of the two moving blocks via connecting rods, V-shaped clamping openings on the inner walls of the two clamping plates, movable openings on the upper surfaces of the two clamping plates, fixed plates fixedly installed on the inner walls of the two movable openings, electric push rods fixedly installed on the outer walls of the two clamping plates via mounting frames, telescopic openings cooperating with the telescopic ends of the electric push rods on the outer walls of the two clamping plates, and movable plates fixedly installed on the telescopic ends of the two electric push rods.

[0007] Preferably, the lifting mechanism includes a servo hydraulic cylinder fixedly installed on the bottom wall of the support frame, and the upper end face of the support frame has a lifting opening that cooperates with the telescopic end of the servo hydraulic cylinder. The telescopic end of the servo hydraulic cylinder is fixedly connected to the bottom wall of the connecting frame.

[0008] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the connecting frame, and the limiting rod slides through the two moving blocks.

[0009] Preferably, two stabilizing rods are fixedly installed on the bottom wall of the connecting frame, and both stabilizing rods slide through into the interior of the support frame.

[0010] Preferably, anti-slip pads are fixedly installed on the inner walls of both fixed plates and both movable plates, and each anti-slip pad is made of silicone.

[0011] Preferably, a controller is fixedly installed on the outer wall of the base, and the controller is electrically connected to the conveying equipment, the servo hydraulic cylinder, the motor and the two electric push rods.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as a fixed plate, electric push rod and moving plate, when filling flexible packaging materials, the electric push rod pushes the moving plate close to the fixed plate. The silicone anti-slip pads on the inner walls of both plates tightly adhere to the opening of the packaging material from both the inside and outside, which can firmly clamp the packaging material and prevent it from wrinkling, deforming or tipping over due to material impact during filling.

[0014] 2. By setting up components such as a bidirectional screw, a moving block, and a clamping plate, the motor drives the bidirectional screw to rotate, which in turn moves the moving block along the limit rod, causing the clamping plate to move. Its inner wall V-shaped clamping opening can quickly adapt to rigid packaging containers such as rectangles and circles to achieve stable clamping. At the same time, in conjunction with the fixed plate and the moving plate, it can flexibly adjust containers of different sizes and quickly switch between rigid and flexible packaging fixing modes, significantly enhancing the versatility of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-7 A pet snack filling auxiliary fixing device includes a base 1, a conveying device 2 fixedly installed on the upper surface of the base 1, a support frame 3 fixedly installed on the back of the base 1, a connecting frame 5 fixedly connected to the inner bottom wall of the support frame 3 through a lifting mechanism, a bidirectional screw 7 rotatably installed inside the connecting frame 5, a motor 8 connected to the bidirectional screw 7 fixedly installed on the outer wall of the connecting frame 5, two moving blocks 10 threadedly installed on the outer wall of the bidirectional screw 7 through a limiting mechanism, clamping plates 12 fixedly connected to the upper surface of each of the two moving blocks 10 through connecting rods 11, V-shaped clamping openings opened on the inner walls of the two clamping plates 12, moving openings opened on the upper surface of the two clamping plates 12, fixed plates 13 fixedly installed on the inner walls of the two moving openings, electric push rods 15 fixedly installed on the outer walls of the two clamping plates 12 through mounting frames 14, telescopic openings that cooperate with the telescopic ends of the electric push rods 15 opened on the outer walls of the two clamping plates 12, and moving plates 16 fixedly installed on the telescopic ends of the two electric push rods 15.

[0025] The lifting mechanism includes a servo hydraulic cylinder 4 fixedly installed on the inner bottom wall of the support frame 3. The upper surface of the support frame 3 has a lifting opening that cooperates with the telescopic end of the servo hydraulic cylinder 4. The telescopic end of the servo hydraulic cylinder 4 is fixedly connected to the outer bottom wall of the connecting frame 5.

[0026] Furthermore, the servo hydraulic cylinder 4 adopts a closed-loop servo control system with a built-in high-precision displacement sensor, which can provide real-time feedback on the position information of the connecting frame 5. Together with the controller 18, it achieves millimeter-level precise lifting control. When it is necessary to fix packaging containers of different heights, the operator only needs to input the target height value on the controller 18, and the servo hydraulic cylinder 4 can quickly respond and drive the connecting frame 5 to lift smoothly. The whole process is free of obvious vibration, ensuring the stability of the movement of components such as the clamping plate 12 and the fixed plate 13. At the same time, the servo hydraulic cylinder 4 is also equipped with an overload protection device. Once the load exceeds the rated pressure, the system will automatically cut off the oil circuit and issue an alarm, effectively preventing equipment damage due to misoperation or excessive weight of the packaging container, and greatly improving the safety and reliability of the device.

[0027] The limiting mechanism includes a limiting rod 9 fixedly installed inside the connecting frame 5, and the limiting rod 9 slides through the two moving blocks 10.

[0028] Furthermore, the limiting rod 9 can restrict the two moving blocks 10, so that the two moving blocks 10 can only move axially along the outer wall of the bidirectional screw 7.

[0029] Two stabilizing rods 6 are fixedly installed on the outer bottom wall of the connecting frame 5, and both stabilizing rods 6 slide through into the interior of the support frame 3.

[0030] Furthermore, high-precision linear bearings are installed at the joints between the two stabilizing rods 6 and the support frame 3, which can effectively reduce the frictional resistance of the connecting frame 5 during the lifting process and ensure the straightness of its movement trajectory. This keeps the sway of the connecting frame 5 within a very small range during the lifting process, thereby ensuring the stability and positioning accuracy of the clamping. In addition, the surface of the stabilizing rods 6 is treated with rust prevention, which can adapt to complex production environments such as humidity and dust, extend service life, and reduce the frequency of equipment maintenance.

[0031] Anti-slip pads 17 are fixedly installed on the inner walls of the two fixed plates 13 and the two movable plates 16. Each anti-slip pad 17 is made of silicone.

[0032] Furthermore, the silicone anti-slip mat 17 has good elasticity and flexibility. When in contact with flexible packaging materials, it can closely conform to the slight undulations on the surface of the packaging materials, increasing friction while avoiding damage to the packaging materials due to rigid compression.

[0033] A controller 18 is fixedly installed on the outer wall of the base 1. The controller 18 is electrically connected to the conveying equipment 2, the servo hydraulic cylinder 4, the motor 8, and the two electric push rods 15.

[0034] Furthermore, the controller 18 has multiple preset working modes, allowing operators to quickly switch equipment operating parameters and workflows according to different pet snack filling processes and packaging material types. For example, for filling liquid snacks with good flowability and filling paste snacks with high viscosity, the corresponding parameter settings can be called to achieve precise control. At the same time, the controller 18 supports data interaction with the factory's production management system, uploading data such as equipment operating status, production quantity, and fault information to the management system in real time. This facilitates production scheduling and data analysis by managers, optimizes the production process, and improves overall production efficiency and management level.

[0035] In use, the controller 18 can control the conveying device 2, the servo hydraulic cylinder 4, the motor 8, and the two electric push rods 15. When filling pet snacks with flexible packaging material, the flexible packaging material can be placed on the upper surface of the conveying device 2, with its opening corresponding to the outlet of the filling device. The controller 18 controls the motor 8 to start, and the motor 8 drives the bidirectional screw 7 to start rotating. Since the limiting rod 9 slides through the two moving blocks 10, it restricts the rotation of the moving blocks 10, so that the two moving blocks 10 can only move along the direction of the limiting rod 9 under the drive of the bidirectional screw 7. Moving towards each other, the moving block 10 drives the clamping plate 12 to move synchronously through the connecting rod 11, thereby placing the two fixed plates 13 at the opening of the flexible packaging material. Then, the servo hydraulic cylinder 4 can be activated. The telescopic end of the servo hydraulic cylinder 4 drives the connecting frame 5 to descend smoothly along the lifting opening of the support frame 3. During this process, the two stabilizing rods 6 on the outer bottom wall of the connecting frame 5 slide synchronously inside the support frame 3, playing a guiding and stabilizing role, preventing the connecting frame 5 from shaking, until the connecting frame 5 drives the clamping plate 12 to move downward, so that both fixed plates 13 descend into the opening of the flexible packaging material.

[0036] Meanwhile, the controller 18 can control the electric push rods 15 on both sides to extend synchronously. The telescopic ends of the electric push rods 15 pass through the telescopic opening of the clamping plate 12, pushing the moving plate 16 to move closer to the fixed plate 13. The silicone anti-slip pads 17 on the inner walls of the fixed plate 13 and the moving plate 16 are tightly fitted to the inner and outer walls of the opening of the flexible packaging material, respectively. As the electric push rods 15 continue to extend, the silicone anti-slip pads 17, with their good flexibility and anti-slip properties, apply uniform pressure to the packaging material from both the inner and outer sides. During this process, the motor 8 synchronously drives the bidirectional screw 7 to rotate. Due to the guiding effect of the limiting rod 9, the two moving blocks 10 move towards each other along the direction of the limiting rod 9. The moving blocks 10 are driven by the connecting rod 11. The moving clamping plate 12 moves, causing the clamping structure composed of the fixed plate 13 and the moving plate 16 to clamp the flexible packaging material while gradually expanding outward with the rotation of the bidirectional screw 7. This dual action of "clamping + expansion" not only firmly clamps the flexible packaging material, but also effectively opens the bag opening. Since the silicone anti-slip pad 17 is soft, it will not damage the flexible packaging material. At the same time, its large friction can effectively prevent the packaging material from sliding during the opening process, ensuring that the bag opening is in a fully open and fixed state, accurately corresponding to the outlet of the filling equipment. This avoids the problem of wrinkles, deformation or tipping caused by the impact of the material during filling, resulting in inaccurate filling position and material overflow.

[0037] If the rigid packaging material with a rectangular or circular outer wall is placed on the conveying equipment 2, when the moving block 10 drives the clamping plate 12 to move through the connecting rod 11, the V-shaped clamping openings on the inner walls of the two clamping plates 12 will play a role. The special structure of the V-shaped clamping openings can fit tightly with the corners of the rectangular packaging material or the arc surface of the circular packaging material. The bidirectional screw 7 is rotated by the motor 8, so that the two clamping plates 12 move towards each other. The V-shaped clamping openings gradually tighten, forming a stable clamping force on the rigid packaging material, ensuring that it will not shift or shake during the filling process. For flexible packaging materials, after the V-shaped clamping openings complete the initial positioning, the fixed plate 13 and the moving plate 16 are used to further fix and open the bag opening, so as to achieve differentiated and precise fixing of packaging materials of different materials.

[0038] Once the packaging material is secured and the bag opening is opened (or rigid packaging material is securely clamped), the controller 18 sends a start signal to the filling equipment. The filling equipment then begins to accurately fill the pet treats into the packaging material. During the filling process, the conveyor 2 remains stationary to ensure the packaging material is in a stable position. Simultaneously, the controller 18 monitors the operating status of the servo hydraulic cylinder 4, motor 8, and electric push rod 15 in real time. If abnormal pressure or displacement deviation is detected, an alarm is immediately issued and the relevant components are stopped to prevent material leakage, equipment damage, or other problems. After filling is completed, the controller 18 controls the motor 8 to reverse, causing the clamping plate 12 to release its grip on the packaging material (for flexible packaging materials, the electric push rod 15 first retracts to reset the moving plate 16, releasing the bag opening). The servo hydraulic cylinder 4 drives the connecting frame 5 to rise and reset, and the conveyor 2 restarts, transporting the filled packaging material to the next process. This completes one full filling and securing operation.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
