Abstract
Description
Technical Field
[0001] This utility model relates to the field of gripper technology, and in particular to a flexible gripper positioning mechanism for a silver ear fungus canning line with shock absorption effect. Background Technology
[0002] The white fungus canning line is a production line equipment used to automate the filling, broth filling, sealing and packaging of white fungus. The gripper positioning mechanism is used to accurately grasp and fix the white fungus or canned container to ensure accurate filling and sealing positions. It is mainly used in key work stations such as white fungus segmentation, filling positioning and pre-sealing correction to improve production efficiency, avoid material deviation or falling, and ensure consistent filling volume and sealing quality.
[0003] Existing filling systems often struggle to balance high-precision filling with vibration absorption when handling cans of varying sizes. Traditional fixed clamping devices are ill-suited for cans of all sizes, especially fragile items like canned tremella. Improper vibration control can not only affect filling accuracy but also lead to product breakage. Furthermore, existing cushioning structures are typically ineffective at absorbing high-frequency vibrations on the filling line, thus impacting filling quality. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a flexible gripper positioning mechanism for a silver ear fungus canning line with shock absorption, aiming to improve the problem that some grippers in the prior art often cannot simultaneously achieve high-precision filling and vibration absorption.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A flexible gripper positioning mechanism for a silver ear can filling line with shock absorption includes a cylinder, a telescopic rod fixedly connected to the output end of the cylinder, a U-shaped fixing frame fixedly connected to the other end of the telescopic rod, and a positioning clamp fixedly connected to the fixing frame.
[0007] The positioning fixture includes a housing, with the outer walls of the housing fixedly connected to the inner walls of the opening of the fixing frame, and two rotating shafts rotatably connected to the inner walls of the housing. Gear rings are fixedly connected to the outer sides of the rotating shafts. A driving component is slidably connected inside the housing, and clamping components are slidably connected to both sides of the housing. Reinforcing components are provided inside the clamping components, and a reset component is provided at the end of the driving component.
[0008] As a further description of the above technical solution:
[0009] The driving component includes a rack plate, the outer side of which is slidably connected to the inside of the housing, and the two sides of the rack plate meshing with the outer sides of the two gear rings respectively. A contact head is fixedly connected to the front end of the rack plate, and a slide rod is fixedly connected to the bottom of the rack plate.
[0010] As a further description of the above technical solution:
[0011] The bottom of the outer casing is provided with a sliding groove, and the outer side of the sliding rod is slidably connected to the inside of the sliding groove;
[0012] As a further description of the above technical solution:
[0013] The clamping component includes two rack plates, the outer sides of which are slidably connected to the inside of the housing, the inner sides of which mesh with the outer side of the gear ring, and a connecting post fixedly connected to the other side of the rack plates. The outer wall of the connecting post is slidably connected to the front end of the housing, and a chuck is fixedly connected to the other end of the connecting post.
[0014] As a further description of the above technical solution:
[0015] The reinforcement includes a fixed cylinder, the outer wall of which is fixedly connected to the inside of the clamp, a piston is slidably connected to the inner wall of the fixed cylinder, a sliding rod is fixedly connected to the front end of the piston, the outer side of the sliding rod is slidably connected to the front end of the fixed cylinder, a silicone top is fixedly connected to the other end of the sliding rod, a compression spring is fixedly connected to the other end of the piston, and the other end of the compression spring is fixedly connected to the inside of the fixed cylinder.

[0018] As a further description of the above technical solution:
[0019] One end of the reset spring is fixedly connected to the outer wall of the housing, and the other end of the reset spring is fixedly connected to the outer wall of the reset plate.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, a dynamic buffer structure is formed by a compression spring system (sliding rod → piston → compression spring) triggered when the silicone tip contacts the can. When the clamps move in opposite directions to hold the can, the compression of the spring automatically adjusts according to the size of the can, while continuously providing a reverse elastic force to counteract vibration. This achieves the ability to adapt to different sizes of silver ear fungus cans while absorbing high-frequency vibrations of the filling line through the elastic damping of the compression spring, ensuring filling accuracy.
[0022] 2. In this utility model, through the linkage design of the reset spring and the rack plate (i.e., the reset spring releases potential energy to drive the reset plate and the rack plate to move in opposite directions), the clamp is automatically triggered to open when the cylinder retracts, and the can is released by physically pushing out the contact head. Thus, it adapts to high-speed filling lines through mechanical triggering, and at the same time, the contact head pushes out to ensure that the can is completely separated from the clamp, avoiding the material jamming problem common in traditional clamping mechanisms.

[0029] 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.
[0030] Reference Figure 1 This utility model provides an embodiment of a flexible gripper positioning mechanism for a silver ear fungus canning line with shock absorption effect. It includes a cylinder 1, with a telescopic rod 2 fixedly connected to the output end of the cylinder 1. The cylinder 1 serves as a power source, driving the telescopic rod 2 to perform linear reciprocating motion via compressed air. A U-shaped fixing frame 3 is fixedly connected to the other end of the telescopic rod 2, and a positioning clamp 4 is fixedly connected to the fixing frame 3. The fixing frame 3 transmits the linear thrust of the cylinder 1 to the positioning clamp 4, forming a rigid connection.
[0031] Reference Figures 1 to 3 The positioning fixture 4 includes a housing 41. The outer walls of the housing 41 are fixedly connected to the inner walls of the opening of the fixing frame 3. Two rotating shafts 42 are rotatably connected to the inner wall of the housing 41. A gear ring 43 is fixedly connected to the outer side of the rotating shaft 42. The rotating shaft 42 serves as the rotation fulcrum of the gear ring 43. A driving member 44 is slidably connected inside the housing 41. Clamping members 45 are slidably connected to both sides of the housing 41. A reinforcing member 46 is provided inside the clamping member 45. A reset member 47 is provided at the end of the driving member 44.
[0032] The driving component 44 includes a rack plate 441, the outer side of which is slidably connected to the inside of the housing 41. The rack plate 441 is used to convert the reaction force of the contact head 442 into the driving force of the gear ring 43. The two sides of the rack plate 441 mesh with the outer sides of the two gear rings 43 respectively. The contact head 442 is fixedly connected to the front end of the rack plate 441, and a slide rod 443 is fixedly connected to the bottom of the rack plate 441. A slide groove 444 is provided at the bottom of the housing 41. The outer side of the slide rod 443 is slidably connected to the inside of the slide groove 444. The slide rod 443 and the slide groove 444 form the sliding pair support point of the rack plate 441, so that the rack plate 441 only moves axially, eliminating the risk of lateral displacement of the rack plate 441 and ensuring the meshing accuracy with the gear rings 43.
[0033] The reset component 47 includes a reset plate 471, the outer wall of which is fixedly connected to the end of a rack plate 441, allowing the reset plate 471 and rack plate 441 to move synchronously. Two limiting rods 472 are fixedly connected to both ends of the reset plate 471. The outer sides of the limiting rods 472 are slidably connected to the inside of the outer casing 41, preventing damage caused by excessive movement of the reset plate 471 and rack plate 441. A reset spring 473 is sleeved on the outer side of the limiting rods 472. One end of the reset spring 473 is fixedly connected to the outer wall of the outer casing 41, and the other end is fixedly connected to the outer wall of the reset plate 471. The reset spring 473 is pre-compressed to store elastic potential energy, releasing energy to drive the reset during the return stroke of cylinder 1.
[0034] Reference Figures 2 to 4 The clamping component 45 includes two rack plates 451. The outer sides of the two rack plates 451 are slidably connected to the inside of the outer shell 41. The inner sides of the rack plates 451 mesh with the outer sides of the gear ring 43. A connecting post 452 is fixedly connected to the other side of the rack plates 451. The outer wall of the connecting post 452 is slidably connected to the front end of the outer shell 41. The connecting post 452 is used to convert the linear motion of the rack plates 451 into the radial clamping action of the clamp 453. The other end of the connecting post 452 is fixedly connected to the clamp 453. The tremella can is initially clamped by the opposing movement of the clamp 453, thereby satisfying the gripping force required to fix the can.
[0035] The reinforcement component 46 includes a fixed cylinder 461, the outer wall of which is fixedly connected to the inside of the clamp 453. A piston 462 is slidably connected to the inner wall of the fixed cylinder 461. A sliding rod 463 is fixedly connected to the front end of the piston 462. The outer side of the sliding rod 463 is slidably connected to the front end of the fixed cylinder 461. A silicone top 464 is fixedly connected to the other end of the sliding rod 463. The silicone material of the silicone top 464 compensates for the shape error of the can by deformation, while increasing the coefficient of friction, thus providing both surface protection and anti-slip function. A compression spring 465 is fixedly connected to the other end of the piston 462. The other end of the compression spring 465 is fixedly connected to the inside of the fixed cylinder 461. The compression spring 465 generates progressive pressure through the piston 462, dynamically adjusting the clamping force during vibration, thereby forming a passive damping system to suppress the transmission of high-frequency vibrations in the filling line.
[0036] Working principle: When in use, cylinder 1 is activated, which drives the telescopic rod 2 to move forward. This, through the fixing frame 3, causes the entire positioning clamp 4 to contact the canned silver ear fungus. After contact, the can is pushed forward and transported to the designated position on the filling line. Once the can is transported to the designated position, it is restrained, and a reverse force is applied to the contact head 442, causing the contact head 442 to slide into the outer shell 41. This causes the rack plate 441 to slide synchronously. During the sliding of the rack plate 441, the sliding rod 443 slides inside the sliding groove 444 to prevent the rack plate 441 from deviating. During the sliding of the rack plate 441, the two gear rings 43 rotate. When the gear rings 43 rotate, they drive the two rack plates 451 to move in opposite directions. This, through the transmission action of the connecting column 452, drives the clamps 453 to move in opposite directions, thus fixing the canned silver ear fungus.
[0037] When the two clamps 453 move toward each other, the silicone top 464 contacts the outer surface of the tremella can, thereby driving the sliding rod 463 and the piston 462 to slide into the fixed cylinder 461, thereby compressing the compression spring 465, and further compressing the tremella can through the reverse elastic force of the compression spring 465, so as to prevent the tremella can from being displaced by vibration on the filling line and affecting the filling effect.
[0038] After filling is completed, cylinder 1 reverses its operation, causing the entire positioning clamp 4 and the canned silver ear fungus to leave the designated position on the filling line. This allows the contact head 442 to be unaffected by resistance. The deformation of the return spring 473 restores the return plate 471 and the limit rod 472 to move in the opposite direction toward the outer shell 41, thereby causing the rack plate 441 to move in the opposite direction. The reverse movement of the rack plate 441 causes the clamp 453 to open, and the filling canned silver ear fungus is pushed out through the ejection of the contact head 442, making it convenient for the next process.
[0039] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
