Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of capping device technology, and more specifically, to an automatic capping torque adjustment mechanical device for pickled vegetable packaging bottles. Background Technology

[0002] In the production of pickled vegetables, the packaging process is crucial. The quality of the screw cap not only affects the product's airtightness, thus impacting the shelf life of the pickled vegetables, but also the ease with which consumers can open the packaging. Currently, common screw cap devices on the market have some shortcomings.

[0003] Some traditional capping devices use a fixed torque, which cannot be adjusted according to factors such as the material of the pickled vegetable packaging bottle, the type of cap, and the sealing requirements. For example, the required capping torque differs between plastic and glass bottles. If a fixed torque is used, plastic bottles may deform and break due to excessive torque, while glass bottles may not seal properly due to insufficient torque, affecting product quality.

[0004] Therefore, we need a capping device to solve the above-mentioned technical problems. Summary of the Invention

[0046] like Figures 1-4 As shown, this illustrates an embodiment of the present disclosure. According to one aspect, at least one embodiment of the present disclosure provides an automatic capping torque adjustment mechanism for pickled vegetable packaging bottles, characterized by comprising a base 1 and a conveying assembly 2, a capping assembly 3, and at least one adjusting assembly 4 disposed on the base 1. The at least one adjusting assembly 4 is uniformly distributed along the conveying direction of the conveying assembly 2. The capping assembly 3 includes…

[0047] A capping head 301 is rotatably mounted on the machine base 1.

[0048] A first drive wheel 302 is rotatably mounted on the base 1 and coaxially arranged with the capping head 301. The adjustment assembly 4 includes...

[0049] At least one second drive wheel 303 is provided, and at least one second drive wheel 303 is coaxially arranged vertically. The second drive wheel 303 is vertically movably mounted on the base 1. The second drive wheel 303 is a frustum.

[0050] A drive belt 304 is fitted onto a second drive wheel 303 and a first drive wheel 302 of the cap assembly 3.

[0051] In this embodiment, the drive motor 405 drives the second drive wheel 303 to rotate, and transmits power to the first drive wheel 302 via the transmission belt 304, which in turn drives the capping head 301 to rotate for capping operation. When it is necessary to adjust the capping torque, the vertical position of the second drive wheel 303 is changed. Since the second drive wheel 303 is truncated cone-shaped, the diameter of its contact point with the transmission belt 304 changes, thereby changing the transmission ratio and adjusting the capping torque. This device achieves flexible adjustment of the capping torque through the adjustment component 4, meeting the capping needs of small and medium-sized pickled vegetable processing plants and multi-variety handmade pickled vegetable production workshops for different packaging bottles and caps.

[0052] Furthermore, the adjustment component 4 also includes,

[0053] The first base 401 is disposed on the base 1.

[0054] The second seat 402 is slidably mounted vertically on the first seat 401, and the second seat 402 has a first threaded groove 421.

[0055] The first screw 403 is rotatably mounted on the first seat 401. The first screw 403 is threadedly engaged with the first threaded groove 421. The rotation of the first screw 403 is used to drive the second seat 402 to slide in the vertical direction.

[0056] In this embodiment, rotating the first screw 403 converts its rotation into linear motion of the second seat 402 in the vertical direction, due to the threaded engagement between the first screw 403 and the first threaded groove 421 on the second seat 402. The second seat 402 then drives the second drive wheel 303 to move vertically, changing the transmission relationship between the second drive wheel 303 and the first drive wheel 302, thus adjusting the capping torque. The structural design of the first seat 401, the second seat 402, and the first screw 403 meets the requirements of precise capping torque adjustment in pickled vegetable production, which involves frequent changes in product specifications and high equipment precision.

[0057] Furthermore, the base 1 has a guide groove 101, the first base body has a sliding part 411, the sliding part 411 is slidably disposed in the guide groove 101, the sliding part 411 has a second threaded groove 412, and the adjustment assembly 4 further includes...

[0058] The second screw 404 is rotatably disposed in the guide groove 101. The second screw 404 and the second threaded groove 412 are threadedly engaged. The rotation of the second screw 404 is used to drive the first seat to slide along the guide groove 101.

[0059] In this embodiment, rotating the second screw 404 causes the first seat 401 to slide along the guide groove 101 because the second screw 404 is threadedly engaged with the second threaded groove 412 of the sliding part 411. The first seat 401 drives the adjusting assembly 4 to move to a suitable position. Then, the vertical position of the second drive wheel 303 is adjusted by the first screw 403 to adjust the capping torque of the packaging bottle at different positions. The first seat 401 is moved horizontally by the second screw 404 to adjust the tension of the transmission belt 304.

[0060] Furthermore, the capping head 301 includes,

[0061] The frame 311 is rotatably mounted on the base 1, and the frame 311 is coaxially arranged with the first drive wheel 302.

[0062] Cover 312, which is vertically movable on the frame 311,

[0063] A first linear drive device 313 is mounted on the frame 311, and the telescopic end of the first linear drive device 313 is connected to the cover 312.

[0064] In this embodiment, the telescopic end of the first linear drive device 313 extends or retracts according to the cap height, driving the cap body 312 to move vertically. After the cap body 312 moves to the appropriate position, the frame 311 drives the cap body 312 to rotate, realizing the capping operation. When the capping head 301 needs to be replaced, the cap body 312 is raised by the first linear drive device 313 for easy disassembly and replacement. The gripper 314 and the connector 315 meet the packaging requirements of caps of different diameters and the requirements for cap gripping stability, improving the versatility and capping quality of the capping head 301.

[0065] Furthermore, the capping head 301 also includes,

[0066] The cover 312 has several grippers 314 distributed along its circumference, and each gripper 314 is hinged at its center to the inner wall of the cover 312.

[0067] The connector 315 is provided, and one end of each of the grippers 314 is hinged to the connector 315. The connector 315 is slidably disposed inside the cover 312. The connector 315 is slidably used to drive the grippers 314 to swing along the central hinge point.

[0068] In this embodiment, the connector 315 slides inside the cap body 312. Since the gripper 314 is hinged to the connector 315, the gripper 314 swings around the central hinge point. When the connector 315 slides in a specific direction, the gripper 314 opens or retracts, thus adapting to caps of different diameters and firmly gripping them. During the capping process, the gripper 314 is in close contact with the cap, ensuring that the cap rotates with the capping head 301. The combination of the gripper 314 and the connector 315 meets the packaging requirements for caps of different diameters and the requirements for cap gripping stability, improving the versatility and capping quality of the capping head 301.

[0069] Furthermore, the capping head 301 also includes a second linear drive device 316, which is disposed on the cap body 312, and the telescopic end of the second linear drive device 316 is connected to the connector 315.

[0070] In this embodiment, the control system sends instructions to the second linear drive device 316 based on relevant information about the bottle cap (such as diameter and position). The telescopic end of the second linear drive device 316 extends or retracts, causing the connecting piece 315 to slide inside the cap body 312, thereby driving the gripper 314 to swing around the central hinge point, realizing the opening and closing of the gripper 314, and completing the accurate gripping and releasing action of the bottle cap. The second linear drive device 316 meets the needs of a highly automated pickled vegetable production environment with extremely high production efficiency requirements, improving the automation level and efficiency of production.

[0071] Furthermore, the conveying assembly 2 includes,

[0072] There are at least two drive shafts 201, each of which is rotatably mounted on the machine base 1. The at least two drive shafts 201 are arranged parallel to each other along the conveying direction.

[0073] A conveyor belt 202 is sleeved on the drive shaft 201 and moves with the drive shaft 201.

[0074] Furthermore, the adjustment component 4 also includes,

[0075] A drive motor 405 is mounted on the second base 402, and the output end of the drive motor 405 is connected to the second drive wheel 303.

[0076] The first handwheel 406 is rotatably mounted on the machine base 1 and is connected to the second screw 404.

[0077] The second handwheel 407 is rotatably mounted on the first seat and is connected to the first screw.

[0078] In this embodiment, the drive motor 405 drives the drive shaft 201 to rotate, and the drive shaft 201 drives the conveyor belt 202 to move through friction. The packaging bottles are placed on the conveyor belt 202 and are transported to the capping station as the conveyor belt 202 moves. By adjusting the rotational speed of the drive shaft 201, the running speed of the conveyor belt 202 can be changed to adapt to different production rhythms. The conveying assembly 2, composed of the drive shaft 201 and the conveyor belt 202, meets the needs of large-scale batch production of pickled vegetables and the conveying of packaging bottles of different shapes, ensuring efficient production.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
