Description

Technical Field

[0001] This utility model belongs to the field of dipped canvas winding technology, specifically relating to a tension adjustment mechanism for a dipped canvas winding device. Background Technology

[0002] The tension adjustment mechanism of the canvas winding device in a PVC dipping machine refers to a mechanism used to precisely control and adjust the canvas tension during the canvas winding process through a series of mechanical or electronic devices. By adjusting the tension of the canvas winding device using this mechanism, it is possible to ensure that the canvas maintains a constant tension during the winding process, thus avoiding problems such as deformation, wrinkling, or breakage caused by uneven tension, guaranteeing the flatness and aesthetics of the product. It also reduces downtime and scrap rates due to tension issues, thereby improving production efficiency and economic benefits. The tension adjustment mechanism of the canvas winding device in a PVC dipping machine is mainly used in the canvas winding process of a PVC dipping production line.

[0003] Chinese Patent Publication No. CN221420144U relates to the field of tension adjustment mechanism technology, and in particular to a tension adjustment mechanism for a canvas winding device of a dipping machine. The mechanism includes a main body, side plates, and a winding roller arranged from left to right. A side plate is located on one side of the main body, and a winding roller is located on one side of the side plate. A controller is located below the winding roller. The canvas main body is tightly adhered to the surface of the winding roller. A first roller is located on one side of the side plate, and a rotating rod is rotatably connected to one side of the side plate. A second roller is located on one side of the rotating rod, and a third roller is located below the second roller. A rotating shaft passes through the third roller, and a connecting block is fixedly connected to the top of the rotating shaft. A bolt is located on one side of the connecting block. A first groove and a second groove are formed inside the rotating rod, and a slide rail passes through the inner side of one end of the rotating rod. In this invention, the double-layered rollers in the adjustment mechanism allow for more precise adjustment of the tension.

[0004] In practical use, although this utility model can usually adjust the tension of the canvas to a certain extent, the existing tension adjustment mechanism of the canvas winding device of the dipping machine usually lacks a buffer structure. As a result, when adjusting the tension of the dipped canvas in actual operation, it is often impossible to achieve a smooth transition. This not only affects the overall efficiency of the dipped canvas winding, but also greatly increases the risk of accidental damage to the dipped canvas. Therefore, the practicality of the tension adjustment mechanism of the canvas winding device of the dipping machine is somewhat lacking. Utility Model Content

[0005] This utility model proposes a tension adjustment mechanism for a canvas winding device of a dipping machine to solve the problem of the lack of a buffer structure in the tension adjustment mechanism of the canvas winding device of the dipping machine in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tension adjustment mechanism for a canvas winding device of a dipping machine, comprising:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Please see Figure 1-4 This utility model provides a tension adjustment mechanism for a canvas winding device of a dipping machine, comprising:

[0029] Support plate 1 and multiple casters 2;

[0030] Two positioning plates 3 are respectively set on both sides of the upper end of the support plate 1. A positioning groove is provided through one side of each of the two positioning plates 3. A winding roller 4 is provided on one side of each of the two positioning plates 3. The two ends of the winding roller 4 are respectively located in the two positioning grooves.

[0031] Mounting plate 5 is set on the upper end of two positioning plates 3. Each of the two positioning plates 3 has a mounting groove adapted to the mounting plate 5 on its upper end. Both ends of the mounting plate 5 are located in the two mounting grooves respectively.

[0032] The limiting plate 6 is set between the two positioning plates 3. The limiting plate 6 has a limiting groove through it and is located at the bottom of the mounting plate 5.

[0033] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, multiple fixing bolts 7 are provided on both sides of the mounting plate 5. The bottom ends of the multiple fixing bolts 7 extend into the two positioning plates 3 respectively. The mounting plate 5 and the limiting plate 6 can be easily installed or removed through the multiple fixing bolts 7 on both sides of the positioning plate 3.

[0034] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the bottom of the mounting plate 5 is equipped with a cylinder 8. The cylinder 8 is existing technology and will not be described in detail here. The output end of the cylinder 8 is located on the upper end of the limiting plate 6. Both mounting slots have a snap-fit ​​groove that penetrates the positioning plate 3 at the bottom. The two ends of the limiting plate 6 pass through the two snap-fit ​​grooves respectively and are slidably connected to the side wall of the snap-fit ​​groove. The snap-fit ​​grooves on the two positioning plates 3 can limit the up and down movement of the limiting plate 6 and prevent it from shifting its position when moving, so as to accurately control the tension of the canvas winding device of the dipping machine.

[0035] Specifically, such as Figure 2 and Figure 4 As shown, rectangular grooves are provided on both the upper and lower sides of the limiting groove, and scraper plates 9 are provided in both rectangular grooves. The two scraper plates 9 are inclined at one end and extend into the rectangular grooves.

[0036] Its design, with movable scraper plates 9 set in two rectangular slots, can not only effectively clean impurities attached to the surface of the dipped canvas and ensure the cleanliness of the canvas, but also play an excellent cushioning role, reducing the impact that may be caused to the dipped canvas during tension adjustment.

[0037] Specifically, such as Figure 2 and Figure 4 As shown, each of the two scraper blades 9 is provided with multiple limiting springs 10 on one side. The other end of the multiple limiting springs 10 is respectively provided on one side of the two rectangular grooves. The multiple limiting springs 10 can limit the position of the two scraper blades 9 so that they can always press against the upper and lower sides of the dipped canvas.

[0038] Specifically, such as Figure 2 As shown, two guide rollers 11 are provided on both sides of the limiting plate 6. The two guide rollers 11 on both sides are rotatably connected between the two positioning plates 3. The two guide rollers 11 on both sides of the limiting plate 6 can limit the position of the dipped canvas.

[0039] Specifically, such as Figure 1 As shown, the take-up roller 4 has a mounting wheel 12 at one end, and a drive motor 13 is located on one side of the positioning plate 3. The drive motor 13 is existing technology and will not be described in detail here. The output end of the drive motor 13 has a drive wheel 14 that meshes with the mounting wheel 12. The drive motor 13 can drive the mounting wheel 12 to rotate through the drive wheel 14, thereby driving the take-up roller 4 to rotate and take up the dipped canvas.

[0040] See Figure 1-4When using the canvas take-up device of the sizing machine to wind up the sizing canvas, the sizing canvas first needs to be passed through the limiting plate 6 and multiple guide rollers 11, and then wound around the take-up roller 4. Next, the drive motor 13 is started, and the output end of the drive motor 13 drives the drive wheel 14 to rotate, which in turn drives the mounting wheel 12 and the take-up roller 4 to rotate, thus winding up the sizing canvas. When it is necessary to adjust the tension of the canvas take-up device of the sizing machine, the cylinder 8 needs to be started. The output end of the cylinder 8 drives the limiting plate 6 to move up and down, and the limiting plate 6 can drive the sizing canvas to move, thereby adjusting its tension and ensuring the efficiency of the sizing canvas winding.

A winding roller 4 is provided on one side of each of the two positioning plates 3. The two ends of the winding roller 4 are respectively located in the two positioning grooves.

[0045] Mounting plate 5 is set on the upper end of two positioning plates 3. Each of the two positioning plates 3 has a mounting groove adapted to the mounting plate 5 on its upper end. Both ends of the mounting plate 5 are located in the two mounting grooves respectively.

[0046] The limiting plate 6 is set between the two positioning plates 3. The limiting plate 6 has a limiting groove through it and is located at the bottom of the mounting plate 5.

[0047] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the two positioning plates 3 are provided with the same mounting plate 15 on one side, and the two positioning plates 3 are provided with the same "U"-shaped fixing frame 16 at one end. The two ends of the fixing frame 16 extend through one end of the two positioning plates 3 into the positioning groove and abut against the upper sides of the take-up roller 4 respectively. A threaded rod 17 is rotatably connected to one side of the mounting plate 15, and a threaded hole adapted to the threaded rod 17 is provided through one side of the fixing frame 16. The threaded rod 17 passes through the threaded hole and is threadedly connected to the side wall of the threaded hole.

[0048] Its design allows the fixed frame 16 to move by rotating the threaded rod 17, and the position of the fixed frame 16 can be locked when the rotation stops. The position of the take-up roller 4 can be limited by the movable fixed frame 16, so that the take-up roller 4 can be installed or removed conveniently.
