[0003] During the production process of laminated films, the base material of the laminated film has elasticity. During the glue coating and conveying process, the processing requirements are relatively strict. It is necessary to control the shrinkage rate, and at the same time, the conveying speed, the amount of glue coating, and the tension degree of the base material need to be coordinated with each other to avoid folds in the laminated film. For this reason, the present application specifically discloses a multi-roll glue coating device for laminated films. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the existing problems and provide a multi-roll glue coating device for laminated films.
[0005] The utility model is realized through the following technical solutions: A multi-roll glue coating device for laminated films includes a frame. On both sides of the top of the frame, wall plates are symmetrically connected. Between one ends of the wall plates, a glue coating roller is rotatably arranged. The glue coating roller is driven by a first motor installed outside the wall plates. Between the wall plates and away from the glue coating roller, a shaft rod is movably arranged. A plurality of pressure wheels are sleeved on the shaft rod at intervals. Inside the shaft rod, rotating shafts are arranged at intervals. Grooved wheels matching the pressure wheels are sleeved on the rotating shafts. The rotating shafts are driven by a second motor. Above the glue coating roller, a glue brush is movably arranged through a top frame.
[0006] As a further improvement of the above solution, slider one is sleeved at both ends of the shaft rod. Slider one is arranged in a waist-shaped hole. The waist-shaped hole runs through the wall plate. The displacement of the shaft rod causes slider one sleeved at the end to displace in the waist-shaped hole.
[0007] As a further improvement of the above solution, both ends of the shaft rod run through the wall plate. End plates are sleeved at both ends of the shaft rod. On one side of the end plate, the telescopic rod end of a first telescopic member is connected. The first telescopic member is installed on the tail frame. The first telescopic member is used to push and pull the shaft rod to displace in the waist-shaped hole through the end plate, so as to achieve the displacement of the pressure wheels sleeved on the shaft rod, and to adjust the plane distance between the pressure wheels and the outer surface of the grooved wheels.
[0008] As a further improvement to the above solution, both ends of the glue brush are symmetrically connected to the second slider through clamping parts. The second slider is clamped in the sliding groove of the vertical frame. A second telescopic part is installed on the vertical frame, and the telescopic rod of the second telescopic part is connected to the glue brush. Guide rods are symmetrically arranged on both sides of the glue brush, and the guide rods slide through the vertical frame. The second telescopic part is used to drive the glue brush to lift and displace, so that the bristle end of the glue brush contacts and rests on the clamping film above the glue application roller. While the glue brush is lifting and displacing, the guide rods on both sides of the glue brush will also lift and displace, and the second sliders at both ends of the glue brush slide and displace in the sliding grooves of the vertical frame.
[0009] As a further improvement to the above solution, a cavity is provided in the brush handle of the glue brush. The cavity communicates with a pipe joint installed on its outer side wall. The pipe joint is connected to an electromagnetic valve through an infusion tube. The electromagnetic valve is connected to an infusion pump through an infusion tube. The infusion tube on the infusion pump is placed in the glue tank. The glue tank is installed on the machine frame. The infusion pump is used to suck the glue liquid from the glue tank into the cavity of the glue brush, and the electromagnetic valve is used to control the infusion flow rate and velocity, so as to control the amount of glue applied. The second telescopic part is used to control the contact amount between the bristle end of the glue brush and the substrate surface, so as to facilitate the effective glue application of the glue brush to the clamping film substrate.
[0010] The utility model has the following advantages compared with the prior art: it has a simple structure, reasonable design, novel and unique idea. The infusion pump sucks the glue liquid from the glue tank into the cavity of the glue application brush, and the electromagnetic valve controls the infusion flow rate and velocity, so as to control the amount of glue applied. The substrate of the clamping film enters the upper groove of the sheave above the glue application roller, and then the pressing wheel presses the glue application surface of the substrate to make the glue liquid evenly adhere to one side of the substrate. In addition, the pressing wheel adjusts the distance from the sheave through the first telescopic part to control the thickness of the glue layer on the substrate. In addition, the second telescopic part controls the contact amount between the bristle end of the glue application brush and the substrate surface, and has the phenomena of stable conveying displacement of the clamping film, uniform glue application, and no folding trend of the clamping film.

[0015] The following further describes the utility model with reference to the drawings.
[0016] As shown in Figures 1 to 4As shown in the figure, a multi-roll gluing device for laminated film includes a frame 1. On both sides of the top of the frame 1, wall panels 2 are symmetrically connected. Between one ends of the wall panels 2, a gluing roller 3 is rotatably arranged. The gluing roller 3 is driven by a first motor 4 installed outside the wall panel 2. At one end of the wall panels 2 away from the gluing roller 3, a shaft rod 6 is movably arranged. A number of pressure wheels 7 are sleeved on the shaft rod 6 at intervals. Inside the shaft rod 6, rotating shafts 5 are arranged at intervals. Grooved wheels 8 matching the pressure wheels 7 are sleeved on the rotating shafts 5. The rotating shafts 5 are driven by a second motor 9. Above the gluing roller 3, a glue brush 15 is movably arranged through a top frame.
[0017] As a further improvement to the above solution, at both ends of the shaft rod 6, a first slider 11 is sleeved. The first slider 11 is arranged in a waist-shaped hole 10. The waist-shaped hole 10 runs through the wall panel 2. The displacement of the shaft rod 6 causes the first slider 11 sleeved at the end to displace in the waist-shaped hole 10.
[0018] As a further improvement to the above solution, both ends of the shaft rod 6 run through the wall panel 2. At the ends of both ends of the shaft rod 6, end plates 12 are sleeved. On one side of the end plate 12, the telescopic rod end of a first telescopic member 13 is connected. The first telescopic member 13 is installed on the tail frame. The first telescopic member 13 is used to push and pull the shaft rod 6 through the end plate 12 to displace in the waist-shaped hole 10, so as to achieve the displacement of the pressure wheels 7 sleeved on the shaft rod 6, and to adjust the plane distance between the pressure wheels 7 and the outer surface of the grooved wheels 8.
[0019] As a further improvement to the above solution, at both ends of the glue brush 15, second sliders 16 are symmetrically connected through clamping members. The second sliders 16 are clamped in the sliding grooves of the vertical frame. A second telescopic member 18 is installed on the vertical frame. The telescopic rod of the second telescopic member 18 is connected to the glue brush 15. Guide rods 17 are symmetrically arranged on both sides of the glue brush 15. The guide rods 17 slide through the vertical frame. The second telescopic member 18 is used to drive the glue brush 15 to lift and displace, so that the brush hair end of the glue brush 15 contacts and rests on the laminated film above the gluing roller 3. When the glue brush 15 lifts and displaces, the guide rods 17 on both sides of the glue brush 15 will also lift and displace, and the second sliders 16 at both ends of the glue brush 15 slide and displace in the sliding grooves of the vertical frame.
[0020] As a further improvement to the above solution, the brush handle of the glue brush 15 is provided with a cavity 22. The cavity 22 communicates with a pipe joint 21 installed on its outer wall. The pipe joint 21 is connected to an electromagnetic valve through an infusion pipe. The electromagnetic valve is connected to an infusion pump 19 through an infusion pipe. The infusion pipe on the infusion pump 19 is placed in a glue tank 14. The glue tank 14 is installed on the frame 1. The infusion pump 19 is used to suck glue liquid from the glue tank 14 into the cavity 22 of the glue brush 15, and the electromagnetic valve is used to control the infusion flow rate and velocity, so as to control the amount of glue applied. The second telescopic member 18 is used to control the contact amount between the brush hair end of the glue brush 15 and the substrate surface, so as to facilitate the effective gluing of the glue brush 15 to the laminated film substrate.
[0021] The working principle of a multi-roll glue coating device for laminated film is as follows: first, the substrate of the laminated film is pulled through the glue coating roller 3 and the groove wheel 8, and then around the pressure wheel 7, and then the telescopic member 18 is adjusted, and the rubber brush 15 is driven to move up and down by the telescopic member 18, so that the bristle end of the rubber brush 15 contacts the laminated film on the top of the glue coating roller 3. When the rubber brush 15 moves up and down, the guide rods 17 on both sides of the rubber brush 15 also move up and down, and the sliders 16 at both ends of the rubber brush 15 slide and move in the slide grooves of the stand;
[0022] The glue liquid is sucked from the glue tank 14 into the cavity 22 of the glue brush 15 by the infusion pump 19, and the infusion flow rate and flow rate are controlled by the solenoid valve to control the glue coating amount. The contact amount between the bristle end of the glue brush 15 and the substrate surface is controlled by the telescopic member 2 18, so that the glue brush 15 can effectively coat the laminated film substrate with glue;
[0023] The telescopic member 13 is used to push and pull the shaft rod 6 through the end plate 12 to move in the waist hole 10, thereby achieving the displacement of the pressure wheel 7 mounted on the shaft rod 6, and adjusting the plane distance between the pressure wheel 7 and the outer surface of the groove wheel 8.
[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
