Description
Technical Field
[0001] This utility model relates to the field of gripper-type box packing machine technology, and in particular to a gripper-type box packing machine for rice packaging lines that adapts to packaging specifications. Background Technology
[0002] As a vital food crop, rice packaging significantly impacts production efficiency and product quality. With the diversification of the consumer market, rice packaging sizes are becoming increasingly diverse, ranging from 5kg family packs to 25kg commercial packs. Traditional fixed-type packing equipment can no longer meet the demands of modern flexible production, making the development of gripper-type packing machines with adaptive packaging size capabilities an urgent industry need.
[0003] Existing gripper-type case packers typically use a fixed mechanical structure to grip and pack packaging bags. Their core component is a set of fixed-position grippers, which open and close via a motor. The working principle of this device is to use the rotational power of the motor, through a linkage mechanism or gear transmission, to open and close the grippers in a fixed position, thereby completing the gripping and placement of the packaging bag. The position and gripping width of the grippers are fixed in the design and cannot be automatically adjusted according to the size of the packaging bag.
[0004] However, existing clamp-type box packers with fixed clamping widths have significant limitations. In actual production, the size of rice packaging bags varies depending on the packaging specifications, but box packers with fixed clamping widths cannot automatically adapt to these different sizes of packaging bags. This necessitates manual replacement of the clamps or adjustment of the mechanical structure when changing packaging specifications, which is not only time-consuming and labor-intensive but also prone to inaccurate adjustments, affecting packing efficiency and quality. Therefore, a clamp-type box packer with adaptive packaging specifications for rice packaging lines is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a gripper-type box packer for rice packaging lines that adapts to packaging specifications.

[0019] As a further description of the above technical solution:
[0020] A sliding block is slidably connected to the outer wall of the first fixed column, and a sliding sleeve is fixedly connected to the top of the sliding block.

[0027] This utility model has the following beneficial effects:
[0028] 1. In this utility model, the screw rod is driven to rotate by the motor-driven linkage block. The rotation of the screw rod causes the connecting block to move, which in turn causes the connecting plate to move, thus moving the fixed plate. This achieves the effect of adaptively adjusting the clamping width, solving the problem that the fixed clamping width cannot be adapted to packaging bags of different sizes, requiring manual replacement of the clamps or adjustment of the mechanical structure. This improves the versatility of the adaptive clamping box packer.
[0029] 2. In this utility model, by pressing the rotating plate, the clamping column is moved to the inside of the first fixed column. Then, the sliding block can be pulled to slide on the outer wall of the first fixed column, which achieves the effect of limiting the rice packaging bag. This solves the problem that the rice bag does not have a limiting function, which causes the bag to slide or deviate during the transportation process after the gripper grabs the rice bag. This improves the stability of the gripper-type box packer that adapts to packaging specifications. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0040] Reference Figure 1 , Figure 4 - Figure 7This utility model provides an embodiment of a gripper-type box-packing machine for rice packaging lines that adapts to different packaging sizes. It includes a support frame 3, a first lifting device 4 fixedly connected to the bottom of the support frame 3, a first support plate 18 at the bottom of the first lifting device 4, a second fixed column 23 fixedly connected to the bottom of the first support plate 18, a second support plate 33 fixedly connected to one end of the second fixed column 23, a motor 19 fixedly connected to the top of the second support plate 33, a linkage block 20 fixedly connected to the output end of the motor 19, a threaded rod 21 rotatably connected to the inner wall of the linkage block 20, and a connecting component on the outer wall of the threaded rod 21. The connecting component controls the gap between the fixed plates 26, thereby adjusting the gap and driving the perforated plate 27 to move, thus achieving adaptive adjustment of the gripping width. This improves the versatility of the gripper-type box-packing machine for rice packaging lines, enabling it to adapt to different packaging sizes of rice.
[0041] The connecting assembly includes a connecting block 22, which is internally threaded to the outer wall of a threaded rod 21. A connecting plate 34 is fixedly connected to the bottom of the connecting block 22, and a slider 25 is fixedly connected to the bottom of the connecting plate 34. A slide rail 24 is slidably connected inside the slider 25. A fixing plate 26 is fixedly connected to the bottom of the connecting plate 34. A gripper assembly is provided on the side wall of the fixing plate 26. The gripper assembly is used to clamp the rice packaging bag and provide support for the rice packaging bag, thereby stabilizing its position during clamping, reducing displacement of the rice packaging bag, and reducing the risk of the rice packaging bag falling accidentally. The gripper assembly includes a perforated plate 27, the side wall of which is fixedly connected to the side wall of the fixing plate 26. A gripper 28 is slidably connected to the outer wall of the perforated plate 27. The gripper 28 is fixedly connected to a hollow column 30. A second hole 29 is provided inside the gripper 28. A spring-loaded component is provided inside the hollow column 30. The spring-loaded component is used to control the position of the gripper 28 on the outer wall of the perforated plate 27. By adjusting the length of the gripper 28, the appropriate gripper length can ensure that the packaging bag is subjected to uniform force during the gripping and placement process, avoiding excessive local force caused by the gripper being too long or too short. This reduces the breakage rate of the gripper-type box packer that adapts to the packaging specifications of the rice packaging line. The spring-loaded component includes a second spring 31. One end of the second spring 31 is fixedly connected to the inside of the hollow column 30, and the other end of the second spring 31 is fixedly connected to a retaining ball 32. The outer wall of the retaining ball 32 is located inside the second hole 29.
[0042] Reference Figure 1 - Figure 3The inner wall of the support frame 3 is provided with a second lifting device 15. A rotating disk 16 is fixedly connected to the top of the second lifting device 15. The rotating disk 16 is made of engineering plastic, which has good wear resistance and self-lubricating properties.

A first conveyor belt 1 is provided on the side wall of the support frame 3. A fixing block 5 is fixedly connected to the top of the first conveyor belt 1. A first fixing column 14 is fixedly connected to the top of the fixing block 5. One end of the first fixing column 14 is fixedly connected to... Connected to the limiting plate 2, the first fixed post 14 has a first hole 13 inside. A sliding block 6 is slidably connected to the outer wall of the first fixed post 14. The sliding block 6 is made of copper alloy, which has good wear reduction and wear resistance. When sliding on the outer wall of the first fixed post 14, it can reduce frictional resistance, making the sliding process smoother and more stable. Its wear resistance also extends the service life of the sliding block 6. A sliding sleeve 7 is fixedly connected to the top of the sliding block 6. A support block 8 is fixedly connected to the outer wall of the sliding sleeve 7. A limiting post 9 is fixedly connected inside the support block 8. The limiting post 9 is made of carbon steel and has... The high hardness allows for stable fixation inside the support block 8, providing a reliable fulcrum for the rotation of the rotating plate 10. During frequent rotation of the rotating plate 10, it is not easily deformed or damaged by stress. A first spring 12 is provided on the outer wall of the sliding sleeve 7. The first spring 12 is made of spring steel, possessing excellent elasticity and fatigue strength. It maintains good elasticity even under repeated tension and compression, providing a stable restoring force for the rotating plate 10 and ensuring that the locking post 11 can accurately engage and disengage from the first hole 13. One end of the first spring 12 is fixedly connected to… The first spring 12 is fixedly connected to the outer wall of the sliding sleeve 7. The other end of the first spring 12 is fixedly connected to the rotating plate 10. The rotating plate 10 is rotatably connected to the outer wall of the limiting post 9. The side wall of the rotating plate 10 is rotatably connected to the side wall of the support block 8. The side wall of the rotating plate 10 is fixedly connected to the locking post 11. The locking post 11 is made of hard alloy material with extremely high hardness. In the process of frequent insertion and disengagement from the first hole 13, it can effectively resist wear and ensure that the locking post 11 always maintains a precise shape and size, thereby stably realizing its limiting and positioning functions. The outer wall of the locking post 11 is set inside the first hole 13.
[0043] Working principle: When using the adaptive packaging specification gripper box packer of rice packaging line, and when adjusting the gripping width, the linkage block 20 is first driven to rotate by the output end of the motor 19. Then, the rotation of the linkage block 20 will drive the internal threaded rod 21 to rotate. During the rotation of the threaded rod 21, the connecting block 22 on the outer wall will be moved to move on the outer wall of the threaded rod 21. Next, during the movement of the connecting block 22, the bottom connecting plate 34 and the fixing plate 26 will be moved to move in position. During the movement of the connecting plate 34, the bottom slider 25 will be moved to slide on the outer wall of the slide rail 24, thereby achieving the effect of adjusting the gripping width. The second support plate 33 is connected to the top of the second support plate 33 by the second fixing column 23, so that the position of the second support plate 33 is fixed.
[0044] Next, when adjusting the length of the gripper 28, simply pull the gripper 28. The gripper 28 will be forced to move the hollow column 30 at the bottom. During the movement of the hollow column 30, the second spring 31 inside will be moved. During the movement of the second spring 31, the locking ball 32 at one end will be moved to move inside the hollow column 30. In summary, during the movement of the locking ball 32, its outer wall will be pressed against the inside of the perforated plate 27, and the locking ball 32 will be pressed against the inside of the second hole 29, thereby locking the position of the gripper 28 and achieving the effect of adjusting the length of the gripper 28.
[0045] Then, when limiting the rice packaging bag, firstly, the rotating plate 10 needs to be pressed. The rotating plate 10 will rotate on the outer wall of the support block 8 under force. At the same time, the rotating plate 10 rotates along the central axis of the limiting post 9. Next, during the rotation of the rotating plate 10, the first spring 12 on the side wall will be driven to contract, and the first spring 12 will give the rotating plate 10 a rebound force. Next, during the rotation of the rotating plate 10, the locking post 11 on the side wall will be driven to rotate. Then, during the rotation of the locking post 11, its outer wall will be locked inside the first fixed post 14, and the outer wall of the locking post 11 will be attached to the inside of the first hole 13. Next, the sliding block 6 can be pulled to slide on the outer wall of the first fixed post 14, thereby adjusting the position of the limiting plate 2 and achieving the effect of limiting the rice packaging bag.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
