Description

Technical Field

[0001] This utility model relates to the field of sleeve processing technology, and in particular to a winding device for processing PVC heat shrink sleeves. Background Technology

[0002] PVC heat shrink tubing is a heat shrink packaging material made of polyvinyl chloride (PVC). It is tubular at room temperature and has a certain degree of flexibility and elasticity. When heated to a certain temperature, it will shrink and tightly wrap around the surface of the packaged object.

The device includes a base plate, a fixing plate on one side of the top of the base plate, a first motor on one side of the fixing plate, and a rotating shaft driven by the first motor inserted into one side of the fixing plate. One end of the rotating shaft has a winding disc with a cavity inside. A second motor is located on one side of the cavity. A bidirectional screw is positioned between the output end of the second motor and the inner wall of the cavity. Both ends of the bidirectional screw have threaded moving blocks. The cavity has openings at both the top and bottom, and the moving blocks have connecting rods passing through the openings at both the top and bottom. The advantages of this invention compared to existing technologies are: it allows for flexible adjustment of the spacing between the dividing discs, offering high applicability; it also removes dust from the surface of the PVC heat shrink tubing, resulting in a more aesthetically pleasing finished product.

[0004] While the above technology has certain improvements, adjusting the distance between the separators by driving a bidirectional screw with a motor can only be applied to the adjustment of two sets of separators. When there are many separators, it is difficult to adjust them synchronously, which will reduce the overall work efficiency in large-scale production. Therefore, a winding device for PVC heat shrink tubing processing is proposed to solve the above problems. Utility Model Content

The guide wheels 2 can provide corresponding tension to the PVC heat shrink tubing. Two sets of support plates 3 are provided, with a drive motor 4 fixedly connected to the left end of the support plate 3.

The adjustment mechanism 7 can be used to synchronously adjust multiple sets of take-up reels 6 to adapt to PVC heat shrink tubing of different diameters and lengths.

[0035] Reference Figures 2-4The adjusting mechanism 7 includes a fixed plate 701, a guide post 702 fixedly connected to the rear end of the fixed plate 701, a movable block 706 slidably connected to the outer wall of the guide post 702, the guide post 702 can guide the movable block 706, allowing it to move only vertically, a fixing member is provided on the inner wall of the movable block 706, the fixing member can limit and fix the movable block 706, a connecting rod 708 is rotatably connected to the inner side wall of the movable block 706, the vertical movement of the movable block 706 can drive the two sets of connecting rods 708 to rotate, a guide block 709 is slidably connected to the inner wall of the fixed plate 701, an X-shaped connecting plate 703 is rotatably connected to the rear end of the guide block 709, and the X-shaped connecting plate 703... The overall length of the connecting plate 703 can be changed, and a corresponding rotating shaft is set in the middle. The guide block 709 is rotatably connected to the rotating shaft. The rear end of the X-shaped connecting plate 703 is fixedly connected to a fixing column 705. Two sets of fixing columns 705 are set so as to control multiple sets of X-shaped connecting plates 703 to move synchronously, thereby adjusting the winding reel 6 synchronously. The front end of the guide block 709 is fixedly connected to a clamping column 710. The clamping column 710 is concave. The outer wall of the winding reel 6 is provided with an annular groove 704. The setting of the annular groove 704 avoids movement interference. The right end of the base 1 is provided with a support moving mechanism 8. The setting of the support moving mechanism 8 can drive the base 1 to move as a whole.

[0036] Reference Figures 3-4 and Figure 6 The fasteners include bolts 707, whose outer wall is threaded onto the inner wall of the movable block 706. The movable block 706 provides a certain amount of movement space for the bolts 707. A threaded hole is opened at the rear end of the guide post 702, and the front end of the bolt 707 is threaded onto the inner wall of the threaded hole. The threaded connection between the two supports and fixes the movable block 706. Multiple sets of threaded holes are provided, which improves the flexibility of the winding reel 6. The output end of the drive motor 4 is fixedly connected to the left end of the winding roller 5. Rotation of the output end of the drive motor 4 drives the winding roller 5 to rotate, thus performing the rotation. The winding process is existing technology and will not be explained in detail here. The bottom end of the fixing plate 701 is fixedly connected to the rear top of the base 1.

[0037] Reference Figures 2-3 and Figure 5The supporting moving mechanism 8 includes a three-phase asynchronous motor 801, which provides a power source. A positioning block 808 is fixedly connected to the upper inner wall of the base 1. Two sets of positioning blocks 808 are provided to provide support. A bidirectional threaded rod 805 is rotatably connected to the inner wall of the positioning block 808. A slider 804 is threadedly connected to the outer wall of the bidirectional threaded rod 805. The rotation of the bidirectional threaded rod 805 drives the two sets of sliders 804 to simultaneously open or close.

A base plate 803 is rotatably connected to the bottom end of the connecting plate 806. The rotation of the connecting plate 806 drives the base plate 803 to move. A telescopic rod 80 is fixedly connected to the top end of the base plate 803. 7. The overall length of the telescopic rod 807 can be adjusted and provides guidance. When the base plate 803 contacts the ground, it enhances the overall stability of the base 1. The bottom end of the base 1 is fixedly connected to a caster wheel 802, which facilitates the movement of the base 1. The left end of the three-phase asynchronous motor 801 is fixedly connected to the right end of the base 1, and the output end of the three-phase asynchronous motor 801 is fixedly connected to the right end of the bidirectional threaded rod 805. The base 1 can support the three-phase asynchronous motor 801, and the rotation of the output end of the three-phase asynchronous motor 801 drives the bidirectional threaded rod 805 to rotate. The top end of the telescopic rod 807 is fixedly connected to the upper inner wall of the base 1. The two are fixed together to guide the base plate 803, so that it can only move vertically.

[0038] Working Principle: Before starting the winding operation, the winding device needs to be adjusted according to the diameter and length of the PVC heat shrink tubing to be processed. The operator first adjusts the position of the winding reel 6 by adjusting the mechanism 7, and rotates the bolt 707 to disengage its front end from the screw hole at the rear end of the guide post 702, thus releasing the restriction on the moving block 706. Due to the guiding effect of the guide post 702 on the moving block 706, the moving block 706 can only slide up and down vertically. The operator pushes the moving block 706 as needed, and the connecting rod 708, which is rotatably connected to the inner side wall of the moving block 706, will rotate as the moving block 706 moves vertically. This is because the upper inner arc surface of the connecting rod 708 is rotatably connected to the outer arc surface of the fixed post 705. Furthermore, the fixed column 705 provides synchronous movement control for multiple sets of X-shaped connecting plates 703. Therefore, when the connecting rod 708 rotates, it drives the connected X-shaped connecting plate 703 to move. The middle rotating shaft of the X-shaped connecting plate 703 is rotatably connected to the guide block 709. The concave clamping column 710 at the front end of the guide block 709 will move with the movement of the guide block 709. The front end of the clamping column 710 is slidably connected in the annular groove 704 opened on the outer wall of the winding reel 6. Through this linkage, the synchronous adjustment of multiple sets of winding reels 6 is realized, so that the interval can adapt to PVC heat shrink tubing of different diameters and lengths. After the adjustment is in place, the bolt 707 is screwed into the appropriate screw hole to reposition and fix the moving block 706, ensuring the stability of the winding reel 6.

[0039] After preparation, turn on the drive motor 4. The output end of the drive motor 4 is fixedly connected to the left end of the take-up roller 5. The rotation of the motor drives the take-up roller 5 to rotate, fixing the starting end of the PVC heat shrink tubing onto the take-up roller 5. As the take-up roller 5 rotates, the PVC heat shrink tubing is wound in an orderly manner around the take-up roller 5 and the take-up reel 6 under the tension provided by the guide wheel 2. When the take-up roller 5 rotates, the annular groove 704 will also rotate to avoid motion interference during winding.

[0040] When the entire winding device needs to be moved, the three-phase asynchronous motor 801 is started. The three-phase asynchronous motor 801 is fixed to the right end of the base 1, and its output end is fixedly connected to the right end of the bidirectional threaded rod 805. After the motor starts, the bidirectional threaded rod 805 begins to rotate. Since the outer wall of the bidirectional threaded rod 805 is threaded with a slider 804, and the two sets of positioning blocks 808 on the upper part of the inner wall of the base 1 guide and support the slider 804, the slider 804 can only move in a straight line along the bidirectional threaded rod 805. When the bidirectional threaded rod 805 rotates, the two sets of sliders 804 will simultaneously disperse or move in a straight line. The bottom end of the slider 804 is rotatably connected to the connecting plate 806. When the slider 804 moves, the connecting plate 806 rotates, thereby driving the base plate 803, which is rotatably connected to its bottom end, to move. The telescopic rod 807 at the top of the base plate 803 is fixedly connected to the upper inner wall of the base 1, providing vertical guidance for the base plate 803 and ensuring its stability. It also restricts the movement of the base plate 803 to only up and down. When the base plate 803 moves downward and contacts the ground, it enhances the overall stability of the base 1. When the base plate 803 is not in contact with the ground, the base 1 can move.

[0041] 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.
