Plastic particles are heated and melted to be precisely coated on the surface of paper, non-woven fabric and other substrates to form a uniform composite film. The core function is to give the substrate waterproof, oil-proof, enhanced texture and mechanical strength and other characteristics, and it is widely used in printing and packaging, food containers, environmental protection handbags and other fields.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. During the conveying process, the two air inlet hoses on the sides of the composite film are connected to the cooling air source and the heating air source, respectively. The heating air source heats the flexible substrate at the bottom of the composite film through the air knife outlet at the bottom, while the cooling air source cools the plastic film at the top of the composite film through the air knife outlet at the top. During the cooling process, the plastic film shrinks and becomes more brittle, while the flexible substrate at the bottom expands due to the heat. The hot and cold air sources generate shear stress and tensile stress in opposite directions at the interface, which enables the plastic film to be quickly peeled off from the surface of the flexible substrate, improving the separation effect between the plastic film and the flexible substrate.

[0020] 2. When the L-shaped bracket moves, it drives the air knife and the connecting pipe to move synchronously. The circular pin limits the strip groove, so that when the connecting pipe moves, the guide strip drives the fixing ring to move, and the circular pin moves relative to the inside of the strip groove. The fixing ring drives the connecting pipe to rotate along the rotating connection of the rotating through hole, and continuously adjusts the contact angle between the air knife outlet and the edge-cutting composite film. While increasing the contact area between the hot and cold air sources and the edge-cutting composite film, it reduces the change in cooling and heating effect as the distance decreases, and improves the stability of the hot and cold air sources for cooling and heating respectively.

[0021] 3. During the conveying process, the suction machine creates negative pressure inside the adsorption housing, which draws the plastic film along the adsorption housing and suction hose into the suction machine. During adsorption, the agitator continuously pushes the two sides of the diced composite film downwards, causing the upward-curving sides to warp downwards under external force. This allows the separated plastic film to slide down along the inclined surfaces on both sides. Furthermore, the external force knocks on the plastic film, causing the cooled and brittle film to fragment, improving the separation effect of the negative pressure adsorption. Simultaneously, the reverse agitation reduces the warping of the diced composite film, preventing it from folding during clamping and conveying. Attached Figure Description

DETAILED DESCRIPTION

[0034] Sliding grooves 8 are formed on the upper and lower sides of the U-shaped frames 6, L-shaped supports 9 are slidingly connected in the sliding grooves 8, and Figure 9As shown, the L-shaped support 9 is provided with a rotating through hole 10, and the rotating through hole 10 is rotatably connected with a communication pipe 11, one end of the communication pipe 11 is fixedly connected with an air knife 12, the air outlets of the two air knives 12 are inclined to the center of the U-shaped frame 6 and parallel to each other, the L-shaped support 9 is fixedly connected with a sealing shell 13, the sealing shell 13 is fixedly connected with an air inlet hose 14, and the sealing shell 13 is connected with the corresponding rotating through hole 10;

[0035] The corresponding two L-shaped supports 9 are provided with a moving assembly, and the corresponding two air knives 12 are provided with an air outlet adjusting assembly, the two L-shaped supports 9 are driven to move close to each other by the moving assembly, and the air outlet angle of the air knife 12 is adjusted by the air outlet adjusting assembly when the L-shaped support 9 moves, and the U-shaped frame 6 is provided with a negative pressure collecting assembly;

[0036] The composite film after the coating is moved and conveyed along the machine frame body 1 in a tension state, and moves on the top of the conveying roller 2, the conveying roller 2 is driven to rotate by the driving unit 3, and the cutting wheel 4 is driven to rotate synchronously after contacting the top of the conveying roller 2 by the action of the displacement rotating assembly, so as to cut the edges of the composite film on both sides, the staff places one end of the cut composite film on both sides between the corresponding two clamping rollers 7, and the two clamping rollers 7 are driven to rotate towards each other by the action of the opposite rotating assembly, and the cut edges of the composite film are synchronously conveyed;

[0037] During the conveying of the edges of the composite film, the two air inlet hoses 14 arranged above and below are respectively connected with a cooling air source and a heating air source, the heating air source heats the flexible base material at the bottom of the composite film through the air outlet of the lower air knife 12, and the cooling air source cools the plastic film at the top of the composite film through the air outlet of the upper air knife 12, the plastic film shrinks and increases its brittleness during the cooling process, and the flexible base material at the bottom expands by heating, the cooling and heating air sources generate shear stress and tensile stress in opposite directions at the interface, so that the plastic film can be rapidly stripped from the surface of the flexible base material, and the separation effect of the plastic film and the flexible base material is improved;

[0038] The air outlets of the two air knives 12 are parallel to each other and form an inclined angle with the composite film, so as to ensure that the moving tracks of the cold and hot air sources are parallel, reduce the influence of the intersection of the cold and hot air sources on the cooling and heating effects, and increase the contact residence time of the cold and hot air sources with the upper and lower surfaces of the composite film through the inclined contact of the cold and hot air sources with the composite film, thereby further improving the separation effect. In the initial state, the two air knives 12 are located on the upper and lower sides inside the U-shaped frame 6, so as to facilitate the staff to pull the edge-cut composite film from between the two air knives 12 to between the clamping rollers 7. Then, the moving assembly drives the two air knives 12 to move close to each other, and the air outlet adjusting assembly adjusts the air outlet angle of the air knife 12. During the process that the air knife 12 moves close to the edge-cut composite film, the air outlet angle of the air knife 12 is adjusted synchronously, so that the distance change between the air outlet and the edge-cut composite film is reduced when the distance between the air knife 12 and the edge-cut composite film is reduced. While reducing the change of the cooling and heating effects of the cold and hot air sources on the edge-cut composite film, the contact residence time of the cold and hot air sources with the upper and lower surfaces of the edge-cut composite film is increased, thereby further improving the separation effect of the plastic film and the flexible base material. Finally, the separated plastic film is collected by the negative pressure collection assembly, and the flexible base material is continuously conveyed between the two clamping rollers 7 and collected separately.

[0040] The first motor 16 drives the first gear 17 to rotate, and the engagement of the first gear 17 with the two racks 18 causes the two L-shaped supports 9 to slide along the corresponding sliding grooves 8, so that the two L-shaped supports 9 move close to each other. When the output shaft of the first motor 16 reverses, the two L-shaped supports 9 move away from each other.

[0041] As a further embodiment of the present application, the air outlet adjusting assembly comprises two fixed rings 19, as shown in Figure 9 The two fixed rings 19 are fixedly connected to the corresponding two communication pipes 11, and the fixed ring 19 is fixedly connected with a guide strip 20, and the guide strip 20 is provided with a strip-shaped groove 21.
