DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a composite film tape glue coating machine, including a positive pressure box 1, the positive pressure box 1 is equipped with a main film winding roller 2, a bottom film winding roller 3, a composite film tape winding roller 4, a first tensioning mechanism 5, a second tensioning mechanism 6, a glue coating mechanism 7, a support frame 8 and a pressing frame 9. The first tensioning mechanism 5 is used to tension the main film, the second tensioning mechanism 6 is used to tension the bottom film, the glue coating mechanism 7 is used to apply glue to the bottom layer of the main film, the pressing frame 9 performs pressing to stick the main film and the bottom film together, and positive pressure fans 10 are installed on both sides of the top of the positive pressure box 1, and filters are installed on the positive pressure fans 10. Box 11, wind windows 12 are provided on both side surfaces of the positive pressure box 1, the positive pressure box 1 is a positive pressure environment, the gluing and bonding pressing of the composite membrane tape are all carried out inside the positive pressure box 1, a filter box 11 is arranged at the air inlet of the positive pressure fan 10, the filter box 11 has a built-in filter element, which can filter the outside air into clean air, and the clean air enters the positive pressure box 1 under the drive of the positive pressure fan 10, and the internal gas of the positive pressure box 1 is discharged through the wind windows 12, and the clean gas is continuously fed into the positive pressure box 1 through the positive pressure fan 10, so that in the process of gluing the composite membrane tape, the internal working environment of the positive pressure box 1 is always in a positive pressure state.

[0024] Among them, the positive pressure box 1, the positive pressure fan 10, the filter box 11 and the wind window 12 constitute a positive pressure dust removal system. The positive pressure dust removal system can effectively prevent pollutants in the external air from entering the glue coating system. Therefore, it can effectively prevent dust particles in the air from adhering to the glue layer, and can ensure the cleanliness of the glue layer during the glue coating process, thereby improving the production and processing quality of the composite membrane tape.

[0025] Among them, the glue coating mechanism 7 includes a glue box 13, and multiple groups of glue transfer rollers 14 are installed at the lower end of the glue box 13, and the glue transfer rollers 14 are rollingly connected to the glue box 13. When the main film moves horizontally between the glue coating mechanism 7 and the support frame 8, under the action of friction, the multiple groups of glue transfer rollers 14 rotate relative to the glue box 13. During the rotation of the multiple groups of glue transfer rollers 14, their own glue is transferred to the film body, and new glue is replenished, so as to achieve continuous gluing of the film body.

[0026] Among them, the multiple groups of glue transfer rollers 14 increase the glue coating area and the number of glue coating times, thereby improving the uniformity of the glue layer of the film body, and further improving the production and processing quality of the composite film tape.

[0027] The glue box 13 is provided with an electric heating wire 15 . The electric heating wire 15 is energized to heat the glue liquid inside the glue box 13 , which can effectively prevent the glue liquid from solidifying, thereby improving the glue coating quality of the glue coating mechanism 7 .

[0028] Among them, a material level sensor 16 and a glue filling port 17 are arranged on the top of the glue box 13, and an electrical socket 18 is arranged at the rear end of the glue box 13. The glue filling port 17 is connected to a glue filling tube 19, and the glue filling tube 19 is connected to a pump body. The material level sensor 16 monitors the material level of the glue liquid inside the glue box 13 in real time. When it is detected that the glue liquid level is insufficient, the pump body works to replenish the glue liquid used for gluing into the glue box 13 through the glue filling tube 19, thereby realizing automatic glue filling without manual operation.

[0029] Among them, a plurality of groups of support rollers 20 are arranged on the support frame 8, and the support rollers 20 are rotatably connected to the support frame 8, and the plurality of groups of support rollers 20 play a supporting role.

[0030] Among them, the first tensioning mechanism 5 and the second tensioning mechanism 6 both include an electric cylinder 21, a pressure sensor 22 is installed at one end of the electric cylinder 21, a tensioning frame 23 is installed at one end of the pressure sensor 22, and a tensioning roller 24 is installed on the tensioning frame 23. The pressure sensor 22 can monitor the pressure exerted on the tensioning roller 24 in real time. The pressure is proportional to the tensioning force, that is, the greater the tensioning force, the greater the pressure monitored by the pressure sensor 22, and conversely, the smaller the tensioning force, the smaller the pressure monitored by the pressure sensor 22.

[0031] Among them, the tensioning force of the membrane is monitored in real time by the pressure sensor 22. When the membrane is too loose, the tensioning force is small, and the tensioning roller 24 at one end is driven by the electric cylinder 21 to move, and the membrane is tensioned until the tensioning force is in the optimal range. Similarly, when the membrane is too tight, the tensioning force is large, and the tensioning roller 24 at one end is driven by the electric cylinder 21 to move, and the membrane is loosened until the tensioning force is in the optimal range.

[0032] Among them, the tensioning force of the membrane body is monitored in real time by the first tensioning mechanism 5 and the second tensioning mechanism 6, and is automatically adjusted to prevent the membrane body from being too tight or too loose, so that the tensioning force of the membrane body is always in the optimal range, effectively ensuring the flatness of the membrane body, avoiding wrinkles on the surface of the composite membrane belt, and making the surface of the composite membrane belt flat and smooth.

[0033] The pressing frame 9 is provided with a first fixing plate 25 , a second fixing plate 26 , a first pressing plate 27 and a second pressing plate 28 .

[0034] The first fixing plate 25 and the first pressing plate 27 are elastically connected via multiple sets of elastic members 29 , the second fixing plate 26 and the second pressing plate 28 are elastically connected via multiple sets of elastic members 29 , and a pressing groove is formed between the first pressing plate 27 and the second pressing plate 28 .

[0035] Among them, the main film and the bottom film pass through the laminating groove, and the main film and the bottom film are pressed together by the first laminating plate 27 and the second laminating plate 28 of the laminating frame 9, so that the main film and the bottom film are bonded together to form a composite film strip, and the film body after bonding is wound up by the composite film strip winding roller 4.

[0036] Working principle: positive pressure box 1, positive pressure fan 10, filter box 11 and wind window 12 constitute a positive pressure dust removal system. The gluing and bonding pressing of the composite membrane strip are all carried out inside the positive pressure box 1. A filter box 11 is arranged at the air inlet of the positive pressure fan 10. The filter box 11 is equipped with a filter element to filter the outside air into clean air. The clean air enters the positive pressure box 1 under the drive of the positive pressure fan 10, and the internal gas of the positive pressure box 1 is discharged through the wind window 12. The clean gas is continuously fed into the positive pressure box 1 through the positive pressure fan 10. During the gluing process of the composite membrane strip, the internal working environment of the positive pressure box 1 is always in a positive pressure state to prevent pollutants in the external air from entering the gluing system. The main membrane is water-tight between the gluing mechanism 7 and the support frame 8. During horizontal movement, under the action of friction, the multiple groups of glue transfer rollers 14 rotate relative to the glue box 13. During the rotation of the multiple groups of glue transfer rollers 14, their own glue is transferred to the film body, and new glue is replenished to achieve continuous gluing of the film body. During the gluing and laminating process, the first tensioning mechanism 5 and the second tensioning mechanism 6 monitor the tensioning force of the film body in real time and automatically adjust it to prevent the film body from being too tight or too loose, so that the tensioning force of the film body is always in the optimal range. The main film and the bottom film pass through the laminating groove, and the main film and the bottom film are pressed together by the first pressing plate 27 and the second pressing plate 28 of the pressing frame 9, so that the main film and the bottom film are bonded together to form a composite film tape. After bonding, the film body is wound up by the composite film tape winding roller 4.
