[0002] Raincoats originated in China. During the Zhou Dynasty, people used the herb "Bi Li" to make raincoats for rain protection. Modern raincoat waterproof fabrics emphasize breathability. Breathable raincoats allow the moisture and heat inside the raincoat to escape when worn, increasing comfort. Therefore, modern raincoat waterproof fabrics mainly use materials such as rubberized cloth, oilcloth, and plastic film. In the raincoat production process, the various parts of the raincoat can be quickly spliced ​​together through heat bonding.

[0003] Patent CN212636633U discloses a plastic heat-sealing device for raincoat sleeves, including a power mechanism for heat-sealing sleeves, an electric push rod, a base, an auxiliary roller, and a support frame. The electric push rod is fixedly connected to the base by bolts, the support frame is mounted on the telescopic part of the electric push rod, the power mechanism is mounted on the support frame, and the auxiliary roller is connected to the base by bearings. This patent proposes to manually stretch the body and sleeves during the heat-sealing operation to prevent wrinkles from forming. However, when using this patent for heat-sealing raincoats, it is difficult to ensure that the body and sleeves remain stretched at all times. Furthermore, wrinkles are prone to appear in the heat-sealed raincoats when operated by different people, resulting in inconsistent overall quality of the raincoats.

[0004] Therefore, it is necessary to design a plastic heat-sealing device for raincoat sleeves that can stretch raincoats during production. Utility Model Content

[0005] To overcome the shortcomings of existing patented methods for heat-sealing raincoats, such as the difficulty in ensuring the body and sleeves remain stretched manually during the process, the tendency for wrinkles to appear when different people operate the process, and the inconsistent overall quality of the raincoats, this invention provides a plastic heat-sealing device for raincoat production that can stretch the raincoat.

[0006] The technical solution is as follows: A plastic heat-sealing device for raincoat sleeves includes a base frame, a processing table, a fixed seat, a cylinder, a fixed plate, an upper hot press plate, guide rods, a support plate, and a lower hot press plate. The processing table is installed on the base frame, and fixed seats are fixedly connected to both sides of the processing table. Cylinders are installed on the fixed seats, and fixed plates are installed on the telescopic rods of the two cylinders. An upper hot press plate is installed on the side of the fixed plate near the processing table.

Detailed Implementation

[0022] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0023] Example 1: A heat-sealing device for plastic sleeves in raincoat production, see reference. Figures 1-5As shown, the assembly includes a base frame 1, a processing table 2, a fixed base 3, cylinders 4, a fixed plate 5, an upper hot press plate 6, guide rods 7, a support plate 8, and a lower hot press plate 9. The processing table 2 is bolted to the base frame 1. Fixed bases 3 are fixedly connected to both sides of the processing table 2. Cylinders 4 are bolted to the front upper part of the fixed base 3. A protective cover 23 is installed on the fixed base 3, covering the cylinders 4, with the cylinder's telescopic rod passing through the protective cover 23. The protective cover 23 protects the cylinders 4 from impact damage. Fixed plates 5 are bolted to the telescopic rods of both cylinders 4. The upper hot press plate 6 is bolted to the bottom of the fixed plate 5. Two guide rods 7 are slidably installed on each of the left and right sides of the processing table 2. A support plate 8 is fixedly connected to the four guide rods 7 by welding. A limit block 22 is fixedly connected to the top rear side of the support plate 8. The limit block 22 is used to limit the upper and lower sleeves of the raincoat, so that the upper and lower sleeves of the raincoat are aligned. A lighting lamp 21 is installed on the processing table 2. The lighting lamp 21 is located above the support plate 8. The lighting lamp 21 is used to illuminate the raincoat during the hot pressing operation, so as to facilitate the observation of the hot pressing status of the raincoat. A lower hot pressing plate 9 is embedded in the support plate 8. The lower hot pressing plate 9 is located above the upper hot pressing plate 6. Five mounting seats 10 are fixedly connected to the front side of the fixing plate 5 by welding. A connecting frame 11 is rotatably set on the mounting seat 10. Two torsion springs 12 are connected between the mounting seat 10 and the connecting frame 11. A rubber roller 13 is rotatably set at one end of the connecting frame 11 near the support plate 8.

[0024] When the raincoat sleeves need to be heat-pressed, the upper and lower sleeve pieces are aligned and placed on the support plate 8. Then, the cylinder 4 is activated, controlling the extension rod of the cylinder 4 to extend. The extension rod of the cylinder 4 drives the fixed plate 5 and the upper heat-pressing plate 6 to move downward. The fixed plate 5 drives the mounting base 10, connecting frame 11, torsion spring 12, and rubber roller 13 to move downward. When the rubber roller 13 contacts the sleeve, the extension rod of the cylinder 4 continues to drive the fixed plate 5 to move downward, causing the connecting frame 11 to rotate upward. The torsion spring 12 deforms, and the rubber roller 13 pushes against the upper and lower sleeve pieces to unfold forward. At the same time, the upper heat-pressing plate 6 and the lower heat-pressing plate 9 press the upper sleeve... The lower edge of the sleeve is pressed down to ensure that the upper and lower sleeves maintain a consistent stretched state during heat pressing, thus ensuring the sleeve remains flat during the heat pressing process and guaranteeing the overall quality of the raincoat heat pressing process. The upper heat pressing plate 6 and the lower heat pressing plate 9 heat up to bond the edges of the upper and lower sleeves together, thereby preventing wrinkles from appearing during heat pressing and improving the flatness of the raincoat sleeves after heat pressing. After the sleeve heat pressing process is completed, the telescopic rod of the control cylinder 4 is shortened. The telescopic rod of the cylinder 4 drives the fixed plate 5 and the upper heat pressing plate 6 to move upward and reset. The rubber roller 13 disengages from the sleeve, and the torsion spring 12 returns to its original state, driving the connecting frame 11 to rotate downward and reset.

[0025] Example 2: Based on Example 1, refer to Figure 2 and Figure 6 As shown, it also includes a mounting plate 14, a guide seat 15, a heat insulation plate 17, and a limiting rod 18. The mounting plate 14 is installed on the processing table 2 by means of bolt connection. The guide seats 15 are installed on the left and right sides of the upper part of the mounting plate 14 by means of bolt connection. The heat insulation plate 17 is slidably arranged on the two guide seats 15. Four limiting holes 16 are opened on both sides of the guide seats 15 and the heat insulation plate 17. The limiting rod 18 passes through the limiting holes 16 on the guide seats 15 and is slidably connected to the heat insulation plate 17.

[0026] Before hot-pressing the sleeves of the raincoat, slide the limiting rod 18 outward to disengage it from the limiting hole 16 on the heat insulation plate 17 and the guide seat 15. Then, move the heat insulation plate 17 up and down to adjust the distance between the heat insulation plate 17 and the support plate 8 to a suitable position so that the staff can observe the hot-pressing status of the sleeves through the gap between the heat insulation plate 17 and the support plate 8. Then, insert the limiting rod 18 into the limiting hole 16 of the heat insulation plate 17 and the guide seat 15 to fix the height of the heat insulation plate 17. This ensures that the heat insulation plate 17 plays a role in heat insulation and protection during the hot-pressing process, ensuring the personal safety of the staff during the hot-pressing process.

[0027] See Figure 3 As shown, it also includes a sliding seat 19 and a screw 20. The sliding seat 19 is fixedly connected to the bottom of the support plate 8. The sliding seat 19 slides on the processing table 2. The screw 20 is rotatably provided at the bottom of the processing table 2. The screw 20 is threadedly connected to the sliding seat 19. A handle is fixedly connected to the lower end of the screw 20 to facilitate the rotation of the screw 20.

[0028] When the height of the support plate 8 needs to be adjusted, the screw 20 is rotated. The screw 20 drives the sliding seat 19 to slide up and down in the processing table 2. The sliding seat 19 drives the support plate 8 to slide up and down under the guidance of the guide rod 7, thereby realizing the adjustment of the height of the support plate 8. This makes it convenient for workers of different heights to use this device to perform heat pressing processing on the sleeves of raincoats, improving the applicability of this device.
