Technical Field
[0001] This utility model belongs to the technical field of polyvinyl chloride processing equipment, and in particular relates to a polyvinyl chloride heat shrink film processing and forming mechanism. Background Technology
[0002] Polyvinyl chloride, abbreviated as PVC, is a polymer formed by the polymerization of vinyl chloride monomers under the action of initiators such as peroxides and azo compounds or under the action of light and heat according to the free radical polymerization mechanism. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. PVC was once the world's largest-produced general-purpose plastic with a wide range of applications, including building materials, industrial products, daily necessities, flooring, floor tiles, artificial leather, pipes, wires and cables, packaging films, foaming materials, sealing materials, and fibers. Now, a polyvinyl chloride heat shrink film processing and forming mechanism is used to complete the processing of polyvinyl chloride heat shrink film.
[0003] However, the existing polyvinyl chloride heat shrink film processing and forming mechanism lacks an effective limiting structure for the polyvinyl chloride heat shrink film. This results in inaccurate alignment between multiple layers of heat shrink film during collection, causing some heat shrink film to be exposed. This not only affects the aesthetics of the heat shrink film but also the stability between the multiple layers of heat shrink film. Utility Model Content
[0004] This invention addresses the problem in existing polyvinyl chloride (PVC) heat shrink film processing and forming mechanisms that lack effective limiting structures for the PVC heat shrink film. This leads to inaccurate alignment between multiple layers of heat shrink film during collection, resulting in some layers being exposed. This not only affects the aesthetics of the heat shrink film but also the stability between the multiple layers. The following technical solution is proposed:

[0006] Preferably, a heat insulation ring is fixedly connected inside both the first and second movable rods, and multiple electric heating tubes are fixedly installed on the outer surface of the heat insulation rings. A wireless temperature measuring probe is fixedly installed inside the first and second movable rods at the position outside the electric heating tubes.

[0009] Preferably, both sides of the two movable blocks are curved and close to each other at one end.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0020] Example 1: This utility model provides a polyvinyl chloride heat shrink film processing and forming mechanism, such as... Figures 1 to 4 As shown, the system includes a fixed frame 1. A control panel 2 is fixedly mounted on the outer surface of the fixed frame 1. The control panel 2 is electrically connected to a motor 11, an electric heating element 13, and a wireless temperature probe 14. A first movable rod 3 is rotatably connected inside the top of the fixed frame 1. A second movable rod 4 is rotatably connected inside the fixed frame 1 below the first movable rod 3. An auxiliary rod 5 is fixedly connected inside the fixed frame 1 below the second movable rod 4. A collecting rod 6 is rotatably connected inside the fixed frame 1 directly in front of the second movable rod 4. An auxiliary motor is fixedly mounted at one end of the collecting rod 6. The auxiliary motor is fixedly mounted inside the fixed frame 1. The auxiliary motor and the control panel 2 are electrically connected. Sliding grooves 7 are provided at the bottom of both ends of the auxiliary rod 5. A slider 8 is slidably connected inside the sliding grooves 7. A movable block 9 is fixedly connected to the bottom of the slider 8. A bidirectional threaded rod 10 is threadedly connected inside the bottom of the movable block 9. A motor 11 is fixedly connected to one end of the bidirectional threaded rod 10. One end of the motor 11 is fixedly mounted inside the fixed frame 1, and the other end of the bidirectional threaded rod 10 is rotatably connected inside the fixed frame 1.
[0021] like Figure 1 and Figure 4 As shown, heat insulation rings 12 are fixedly connected inside the first movable rod 3 and the second movable rod 4. Multiple electric heating tubes 13 are fixedly installed on the outer surface of the heat insulation rings 12. Wireless temperature probes 14 are fixedly installed inside the first movable rod 3 and the second movable rod 4 at positions outside the electric heating tubes 13. Since the electric heating tubes 13 can generate heat, the heat will be transferred to the inside of the first movable rod 3 and the second movable rod 4 through the air, and then to the outer surface of the first movable rod 3 and the second movable rod 4. The wireless temperature probes 14 can monitor the temperature inside the first movable rod 3 and the second movable rod 4 and transmit it to the control panel 2 in real time. The temperature value is displayed in real time through the control panel 2, which can preheat the first movable rod 3 and the second movable rod 4 to prevent the heat shrink film from shrinking or deforming due to temperature difference when in contact, thereby improving the protective properties of the heat shrink film and ensuring the product quality of the heat shrink film.
[0022] like Figure 1 and Figure 3 As shown, the slider 8 is T-shaped. The width of the end of the slider 8 near the movable block 9 is smaller than the width of the other end, which can provide stable support and prevent the slider 8 from shifting its position when it moves, thus improving the stability of the slider 8 when it moves.
[0023] like Figure 1 and Figure 3As shown, the top of the movable block 9 is arc-shaped, and the top surface of the movable block 9 is in contact with the outer surface of the auxiliary rod 5, ensuring that when the heat shrink film contacts the outer surface of the auxiliary rod 5, the movable block 9 can contact the heat shrink film, thus ensuring that the movable block 9 can work normally.
[0024] like Figure 1 and Figure 3 As shown, the two movable blocks 9 are close to each other on both sides with arc surfaces. Since the arc surfaces are smooth, they prevent the heat shrink film from being worn when the movable blocks 9 come into contact with it, thus improving the protective properties of the heat shrink film.
[0025] like Figure 1 and Figure 4 As shown, the distances from the outer surfaces of the multiple electric heating tubes 13 to the inner walls of the first movable rod 3 and the second movable rod 4 are all equal, ensuring that the temperatures of the outer surfaces of each area of the first movable rod 3 and the second movable rod 4 are equal, preventing the heat shrink film from shrinking or deforming due to temperature differences.
[0026] Working principle: In actual use, when heat shrink film needs to be processed, the electric heating tube 13 is activated through the control panel 2. First, the formed heat shrink film passes through the back of the first movable rod 3, then through the front of the second movable rod 4, then through the bottom surface of the auxiliary rod 5, and finally through the top surface of the collecting rod 6. Then, the distance between the two movable blocks 9 is adjusted according to the width of the heat shrink film. The motor 11 is activated through the control panel 2. The output end of the motor 11 rotates, driving the bidirectional threaded rod 10 to rotate synchronously. The rotation of the bidirectional threaded rod 10 drives the movable blocks 9 at both ends to move synchronously along the outer surface of the auxiliary rod 5. The movement of the movable blocks 9 drives the slider 8 to slide synchronously inside the slide groove 7. When the distance between the movable blocks 9 at both ends is equal to the width of the heat shrink film, the position of the movable blocks 9 is adjusted. Then, the auxiliary motor is activated through the control panel 2. The auxiliary motor drives the collecting rod 6 to rotate synchronously, thereby realizing the collection of the heat shrink film. It can limit the position of the heat shrink film and ensure that the position of the heat shrink film will not shift when collecting the heat shrink film, thus improving the heat shrink film collection efficiency and product quality.
[0027] Then, because the electric heating tube 13 can generate heat, the heat will be transferred through the air to the inside of the first movable rod 3 and the second movable rod 4, and then to the outer surface of the first movable rod 3 and the second movable rod 4. The wireless temperature probe 14 can monitor the temperature inside the first movable rod 3 and the second movable rod 4 and transmit it to the control panel 2 in real time. The temperature value is displayed in real time through the control panel 2, which can preheat the first movable rod 3 and the second movable rod 4 to prevent the heat shrink film from shrinking or deforming due to temperature difference when in contact, thereby improving the protective properties of the heat shrink film and ensuring the product quality of the heat shrink film.
[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
