Description

Technical Field

[0001] This application relates to the field of salt bag making technology, and more specifically, to a tension stabilizing mechanism for salt bag making. Background Technology

[0002] Maintaining stable tension is crucial in the salt bag manufacturing process, as it directly affects packaging quality. Unstable tension can cause the packaging film to stretch or shrink during transport, leading to deviations in bag dimensions (such as length and width). These deviations not only affect the product's appearance but may also prevent proper sealing or transportation due to non-standard bag sizes. Furthermore, unstable tension negatively impacts subsequent sealing processes.

[0003] Currently, bag-making machines use only a simple feeding tray to transport the packaging film. When there is a waiting period for feeding, the packaging film on the feeding tray becomes loose, resulting in unstable tension and affecting bag production.

[0004] In view of this, the present application aims to provide a tension stabilizing mechanism for salt bag making to better solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] See Figures 1-3 As shown, the salt bag making tension stabilizing mechanism described in this embodiment includes a frame 1, a feeding unit 2, and a pressing unit 3. The feeding unit 2 is provided with a feeding disc 21 and a braking structure 22. The feeding disc 21 and the braking structure 22 are respectively installed on the frame 1, and the braking structure 22 is in contact with the feeding disc 21 for feeding and braking the feeding disc 21. The pressing unit 3 is provided with a pressing seat 31 and a pressing element 32. The pressing seat 31 is installed on the frame 1, and the pressing element 32 is installed on opposite sides of the pressing seat 31 for pressing the packaging film on the pressing seat 31.

[0028] This embodiment has a simple structure and reasonable design. By setting a brake structure 22 on the feeding tray 21 and setting a pressing unit 3, the tension of the packaging film during the conveying process can be kept stable, thus achieving better bag making production.

[0029] In practical use, during the feeding process, the pressing unit 3 is opened and no pressing is performed. The brake structure 22 is pulled down and does not brake at this time. When the front does not need to feed and enters the processing waiting position, the brake structure 22 starts to reset and brake due to the loss of pulling force, so as to prevent the packaging film of the feeding tray 21 from continuing to feed and becoming loose and sagging. Then the pressing unit 3 presses down on the packaging film. Through the cooperation of the two, the tension of the feeding process is kept stable.

[0030] In some specific embodiments, the brake structure 22 is provided with a brake wheel 221, a brake arm 222, a brake band 223, and a reset member 224. The brake wheel 221 is coaxially mounted with the feed tray 21. The middle part of the brake arm 222 is rotatably mounted on the frame 1 through a bearing member 225. Both ends of the brake arm 222 are connected to the frame 1 through the reset member 224. One end of the brake arm 222 is provided with a guide roller 226 for the packaging film to pass through. One end of the brake band 223 is mounted on the frame 1, and the other end passes through the brake wheel 221 and is connected to the brake arm 222.

[0031] Specifically, the brake band 223 is a belt, and the reset member 224 is a tension spring.

[0032] In this embodiment, the brake structure 22 is specifically shown. In actual use, during the feeding process of the feeding tray 21, the packaging film on the feeding tray 21 passes through the guide roller 226, presses down the top of the brake arm 222, and drives the connecting belt to lift up, so as to release the feeding tray 21 and realize feeding. When there is no tension at the processing front end, the top of the brake arm 222 lifts up, and the bottom of the brake arm 222 presses down the brake band 223, so that the brake band 223 presses the brake wheel 221, realizing the braking of the feeding tray 21. The braking control is precise. At the same time, in conjunction with the pressing unit 3 pressing down, it is ensured that there is no situation such as the packaging film retraction during the feeding process, thereby ensuring stable tension during the feeding process and achieving better salt bag making processing.

[0033] In some embodiments, the frame 1 is provided with a mounting bracket 11 for mounting the feeding unit 2, and the mounting bracket 11 is provided with a limiting wheel 12 for limiting the position of the brake band 223.

[0034] In this embodiment, by setting up a mounting bracket, the feeding unit 2 can be easily and quickly disassembled and maintained. Its structure is simple and highly practical.

[0035] In some embodiments, the pressing element 32 is provided in a group, and the group of pressing elements 32 is installed on opposite sides of the pressing base 31. Each group of pressing elements 32 is provided with a driving part 321 and a pressing plate 322. The driving part 321 is installed on the pressing base 31 and is connected to the pressing plate 322 through a hinge structure, and is used to drive the pressing plate 322 to rotate and press against the pressing base 31.

[0036] Specifically, the clamping plate 322 is provided with a silicone strip 323.

[0037] Specifically, the drive unit 321 is equipped with a drive cylinder.

[0038] This embodiment specifically illustrates the structural configuration of the pressing component 32. The driving unit 321 pushes the pressing plate 322 through a hinge structure to achieve pressing. The structure is compact and easy to control. Simultaneously, by providing a silicone strip 323 on the surface of the pressing plate 322, the anti-slip effect between the pressing plate 322 and the packaging film is enhanced, preventing slippage. Furthermore, the elastic deformation of the silicone can buffer the pressing force, preventing scratches on the film surface from hard materials, making it highly practical. In this embodiment, for the single-sided pressing plate 322, a set of symmetrically arranged cylinders can be used for pressing drive to ensure pressing force. During the pressing process, the cylinders rise, the hinge position rotates, causing the pressing plate 322 to press down, achieving pressing. When release is needed, the cylinders return to their original position, the pressing plate 322 is pulled up, and release is completed.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
