AI Technical Summary
The existing heat-binding machines cause the plastic film to shrink during the heating process, affecting the aesthetics and sealing of the finished product. When the high-temperature heating head is not in contact, it may cause early deformation of the plastic film, affecting the heat sealing accuracy and production quality.
A plastic film heat-binding machine including a dispersion roller and a contact switch is designed. The dispersion roller unfolds the plastic film during the heat sealing process to maintain flatness. The contact switch avoids early deformation through gradual heating, ensuring the sealing and quality of the heat seal.
The flatness and sealing of the plastic film after heat sealing is achieved, avoiding the generation of gaps, and improving processing quality and production efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat sealing machines, in particular to a plastic film heat sealing machine. Background Art
[0002] The heat sealing machine can heat the plastic film so that the plastic film sticks together after heating. The heat sealing machine has a wide range of applications and is generally used for packaging sealing and material splicing.
[0003] According to the existing technology, when the heat sealing machine is working, the heating head needs to be aimed at the plastic film that needs to be sealed. When the plastic film passes through, the sealing part will be heat-sealed. However, during the heat sealing process, due to the high temperature, the plastic film will shrink. Although the heat sealing can be completed, the shrunk plastic film will affect the appearance of the finished product, and the shrunk part may also cause the hot air part to tear and cannot be sealed. At the same time, when the hot air is working, if the temperature of the heating head is too high, the plastic film will shrink before it contacts the plastic film, which will affect the accuracy of the heat sealing and the quality of production and processing.

DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0022] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.
[0023] A plastic film heat sealing machine provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.
[0024] Combination Figure 1-4 As shown, the utility model provides a plastic film heat sealing machine, comprising a table body 1, a support plate 2 is fixedly connected to the top of the table body 1, a first motor 3 is fixedly connected to the top of the support plate 2, a threaded rod 4 is fixedly connected to one end of the first motor 3, a threaded block 5 is threadedly connected to one end of the threaded rod 4 in a through-shaped manner, and a connecting block 6 is fixedly connected to one side of the threaded block 5;
[0025] A moving box 7 is fixedly connected to the bottom of the connecting block 6, a second motor 8 is fixedly connected to the inner wall of the moving box 7, one end of the second motor 8 is fixedly connected to a first gear 9, one side of the first gear 9 is meshedly connected to a second gear 10, one side of the second gear 10 is fixedly connected to a connecting shaft 11, one end of the connecting shaft 11 is fixedly connected to a third gear 12, one side of the third gear 12 is meshedly connected to a fourth gear 13, one end of the fourth gear 13 is fixedly connected to a rotating shaft 14, and one end of the rotating shaft 14 is fixedly connected to a dispersion roller 15;
[0026] One end of the threaded block 5 is slidably connected to the side wall of the support plate 2 in a penetrating manner. A placement table 24 is fixedly connected to the top of the table body 1. A conveying roller 25 is slidably connected to the top of the placement table 24 in a penetrating manner.
[0027] In the first embodiment, the second motor 8 drives the first gear 9 and the second gear 10 to mesh, and drives the connecting shaft 11 to rotate during the meshing process. The connecting shaft 11 drives the third gear 12 and the fourth gear 13 to mesh during the rotation, and then drives the rotating shaft 14 to rotate. The rotating shaft 14 can drive the dispersion roller 15 to rotate when rotating. The dispersion roller 15 can unfold the heat-sealed plastic thin surface when rotating, thereby ensuring that the plastic film can be flat during heat sealing. This can not only ensure the aesthetics after processing, but also ensure that the wrinkles of the plastic are reduced. Reducing wrinkles will reduce the generation of gaps, thereby ensuring the quality of the finished product.
[0028] One end of the rotating shaft 14 is fixedly connected to a heating mechanism, one end of the rotating shaft 14 is rotatably connected to a heat conductive block 16 in a through-like manner, the top of the heat conductive block 16 is slidably connected to a first contact switch 17 in a through-like manner, one side of the first contact switch 17 is fixedly connected to a connecting rod 19, the connecting rod 19 is L-shaped, one end of the connecting rod 19 is fixedly connected to a limit block 20, one side of the limit block 20 is fixedly connected to a support block 22, the bottom of the limit block 20 is fixedly connected to a spring 21, one end of the support block 22 is slidably connected to the bottom of the moving box 7, the inner wall of the moving box 7 is fixedly connected to a heating box 23, and one side of the heating box 23 is fixedly connected to a second contact switch 18.
[0029] In the second embodiment, the first motor 3 controls the threaded block 5 on the threaded rod 4 to move, thereby controlling the height of the moving box 7. The support block 22 is inserted into the placement table 24 through the moving box 7 for limit fixing. When the second motor 8 is started, the support block 22 supports the connecting rod 19 on the limit block 20 to move, thereby controlling the first contact switch 17 and the second contact switch 18 to approach each other, and starting the heating box 23. This ensures that before heat sealing, the dispersion roller 15 will not generate high temperature to affect the heat sealing of the plastic film, thereby ensuring that the plastic film will not be deformed prematurely due to the approach of high temperature before heat sealing, thereby ensuring the quality of heat sealing, reducing the number of repeated processing, and saving production and processing costs.
[0030] The working principle and use process of the utility model are as follows: the threaded block 5 on the threaded rod 4 is controlled to move by the first motor 3, and the threaded block 5 can control the moving box 7 on the connecting block 6 to move when moving, and then the moving box 7 drives the support block 22 at the bottom to contact the groove on the placement table 24, thereby completing the limit fixation. During the contact process, the support block 22 drives the first contact switch 17 and the second contact switch 18 on the connecting rod 19 to contact through the limit block 20, so that the heat conductive block 16 transfers the heat to the dispersion roller 15, and then the second motor 8 is started to drive the first gear 9 to mesh with the second gear 10, and the second gear 10 drives the third gear 12 on the connecting shaft 11 to mesh with the fourth gear 13, and then drives the dispersion roller 15 on the rotating shaft 14 to rotate.
