Description

Technical Field

[0001] The utility model relates to the field of packaging bag film processing, in particular to an edge clamping, cooling and separating device for an edge clamping film. Background Art

[0002] The edge film is generally blown by a film blowing machine (three-layer co-extrusion film blowing machine). First, the raw material is heated and melted at high temperature, and then a sleeve-shaped film is blown out by the film blowing unit. Then, the edge of the edge film is folded and formed by the edge forming unit. Two inward-folded edges are folded on both sides of the edge film, and finally the film is rolled up by the winding unit, that is, the material is collected. The edge film is transported or conveyed by multiple rollers from blowing to rolling. However, since the raw material is melted by high-temperature heating, the sleeve-shaped film blown out by the film blowing unit itself has a certain temperature. In addition, the temperature generated by the various components of the film blowing machine and the transfer and conveying rollers for a long time will cause the two edges folded together on both sides of the edge film to be heated and stuck together. When rolled together, the edges on both sides of the edge film are difficult to separate after naturally cooling down, and the sticky parts are easily torn when separated manually, which causes damage to the appearance of the edge film, which is not beautiful and affects the use. Therefore, it is necessary to cool and separate the stuck edges before rolling. Utility Model Content

[0005] Preferably, the blowing nozzle is a flat nozzle.

[0006] In order to facilitate the control of the movement of the two air blowing positioning seats, a driving device for driving the two air blowing positioning seats to move back and forth is also arranged on the film blowing machine body.

[0007] Furthermore, the driving device includes a driving screw module fixed on the film blowing machine body, a bidirectional screw arranged on the driving screw module, the bidirectional screw is symmetrically provided with two sliders, the two blowing positioning seats are respectively fixed on the two sliders, and the driving screw module is also provided with a driving motor for driving the bidirectional screw to rotate.

[0008] In order to increase the sweeping area of ​​the wind blown out by the blowing nozzle, the two blowing nozzles are both arranged to be inclined inwards, and the angle formed between the two blowing nozzles is 60 to 90 degrees.

[0009] In order to facilitate the control of the amount of air blowing, a control valve for controlling the air output is also provided on the air blowing pipe.

[0010] The beneficial effects of the utility model are as follows: before the edge film is rolled up, the edge of the edge film on both sides is cooled by the blowing device arranged on the film blowing machine body, and the sticky edge is separated by the wind blown from the blowing nozzle, so that the sticky edge of the edge film on both sides will not be damaged during separation, and the integrity and beauty of the appearance of the edge film will be protected, and the efficiency is high. At the same time, the position of the blowing nozzle can be easily adjusted by the driving device to be suitable for edge films of different widths. In addition, the blowing nozzle is flat, and the angle formed between the two blowing nozzles is 60 to 90 degrees, which can increase the wind sweeping area blown by the blowing nozzle and improve the cooling and separation efficiency.

[0018] Examples, such as Figure 1-6As shown, a clamping cooling and separation device for a clamped film comprises a film blowing machine body 1, and a clamping forming unit 13 arranged on the film blowing machine body 1. A first pulling guide roller 11 and a second pulling guide roller 12 are horizontally arranged from top to bottom on the film blowing machine body 1 behind the clamping forming unit 13. First, a cylindrical film is blown out by the film blowing forming unit 14, and then the two sides of the film are folded into clamped edges by the clamping forming unit 13. After the clamping edge is formed, the clamped film is continuously transported to the winding unit via the first pulling guide roller 11 and the second pulling guide roller 12. During transportation, the clamped film is vertically transported downward along the outer sides of the first pulling guide roller 11 and the second pulling guide roller 12, and finally wound up by the winding unit 15. A guide rod 2 is horizontally arranged on the film blowing machine body 1 between the first pulling guide roller 11 and the second pulling guide roller 12. The first pulling guide roller 11, the second pulling guide roller 12 and the guide rod 2 are all arranged in parallel. In order to avoid interference between the guide rod 2 and the components on the film blowing machine body 1, the guide rod 2 is arranged on the outside of the edge film and is not on the same side of the edge film as the first pulling guide roller 11 and the second pulling guide roller 12.

[0019] In order to achieve blowing, two blowing devices 3 with adjustable positions are symmetrically arranged on the guide rod 2, and the blowing device 3 includes a blowing positioning seat 31 movably arranged on the guide rod 2, and the positions of the two blowing positioning seats 31 on the guide rod 2 can be adjusted according to the width of the clamping edge film. The blowing positioning seat 31 is provided with a sliding hole 311 adapted to the guide rod 2, and the blowing positioning seat 31 is fixed with a blowing pipe 32 by a buckle 35. The buckle 35 is fixed on the blowing positioning seat 31, and the buckle 35 is provided with a clamping hole 351 adapted to the blowing pipe 32. It should be noted that the blowing pipe 32 can be a universally adjustable bamboo tube, or a hard tube that can support the blowing nozzle 33. The air outlet end of the blowing pipe 32 is provided with a blowing nozzle 33, the blowing nozzle 33 is located at the edge seam of the edge film, and the air outlet direction of the blowing nozzle 33 is opposite to the conveying direction of the edge film, preferably, the blowing nozzle 33 is a flat nozzle. The air inlet end of the blowing pipe 32 is connected to an air pipe 34, and the air pipe 34 is a hose, and the other end of the air pipe 34 is connected to an air pump 4.

[0020] The working principle of the blowing device 3 is as follows: in actual operation, the clamped edge film after clamping is formed is conveyed vertically downward along the outer sides of the first pulling guide roller 11 and the second pulling guide roller 12. While conveying, air is blown toward the clamping edge seam formed by the two clamping edges of the clamped edge film through the blowing nozzle 33, so that the clamping edge seam that is stuck together due to the heat is cooled and blown apart, and the separated two clamping edges pass through the inner side surface 331 and the outer side surface 332 of the blowing nozzle and continue to be conveyed downward to the winding unit 15 for winding.

[0021] In order to facilitate the control of the positions of the two blowing positioning seats 31 on the guide rod 2, the film blowing machine body 1 is also provided with a driving device 5 for driving the two blowing positioning seats 31 to move back and forth. The driving device 5 includes a driving screw module 51 fixed on the film blowing machine body 1, a bidirectional screw 52 arranged on the driving screw module 51, and two sliders 53 are symmetrically arranged on the bidirectional screw 52. The two blowing positioning seats 31 are respectively fixed on the two sliders 53, and the driving screw module 51 is also provided with a driving motor 54 for driving the bidirectional screw 52 to rotate. The bidirectional screw 52 is driven to rotate forward by the driving motor 54, thereby driving the two sliders 53 on the bidirectional screw 52 to move toward each other; the bidirectional screw 52 is driven to reverse by the driving motor 54, thereby driving the two sliders 53 on the bidirectional screw 52 to move in the opposite direction. In addition, the two sliders 53 are driven to move symmetrically by the driving device 5 and guided by the guide rod 2, so that the stability of the two blowing positioning seats 31 can be ensured.

[0022] To ensure the blowing effect, the two blowing nozzles 33 are both inclined inwards, and the angle formed between the two blowing nozzles 33 is 60 to 90 degrees.

[0023] In order to be suitable for edge films of different thicknesses and prevent excessive air volume from damaging thin edge films, a control valve 321 for controlling the air volume is further provided on the blowing pipe 32. The control valve 321 is preferably an electromagnetic control valve for easy regulation.
