Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof sheet production, in particular to a device for roughening the surface of a plastic sheet. Background Art

[0002] Waterproof sheet production typically involves rolling plastic sheets. Because the surface of a plastic sheet is too smooth, it's not conducive to the adhesion of interface materials. Therefore, the surface of the plastic sheet needs to be roughened to make the originally smooth surface rougher, allowing for better absorption of glue or other coating materials. The current roughening method involves releasing high-voltage electricity to shock the surface of the plastic sheet, invigorating the molecules on the plastic surface and roughening the smooth surface. However, the high-voltage electric shock roughening treatment is currently only performed on one side, which is inefficient. Both sides of the plastic sheet used to produce waterproof sheet need to be roughened, and the existing method is too inefficient, so improvements are necessary. Utility Model Content

[0003] In order to solve the above-mentioned defects of the prior art, the present application provides a plastic sheet surface roughening device, which can simultaneously roughen both sides of the plastic sheet used for producing waterproof sheets, thereby effectively improving production efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] A device for roughening the surface of a plastic sheet, comprising:

[0006] A support platform is provided with a first discharge electrode and a second guide roller on the top thereof, wherein the discharge direction of the first discharge electrode is toward the bottom of the first guide roller, the first guide roller is spaced above the first discharge electrode, and the second discharge electrode is spaced above the second guide roller, and the discharge direction of the second discharge electrode is toward the top of the second guide roller;

[0007] a first step-up transformer connected to the first discharge electrode;

[0008] a second step-up transformer connected to the second discharge electrode;

[0009] The controller is connected to the first step-up transformer and the second step-up transformer.

[0010] Furthermore, a third guide roller is provided at a distance from the second guide roller on the side of the first discharge electrode away from the second guide roller, and the top height of the third guide roller is higher than the bottom height of the first guide roller.

[0011] Furthermore, the first guide roller and the second discharge electrode are both fixed under a top plate, and the top plate is connected to the support platform.

[0012] Furthermore, both sides of the top plate are respectively connected to the telescopic ends of two cylinders, and the cylinders are fixed to the support platform.

[0013] The beneficial effects of the utility model are:

[0014] 1. It can simultaneously roughen both sides of the plastic sheet used to produce waterproof sheets, effectively improving production efficiency.

[0015] 2. By adjusting the extension distance of the cylinder, the distance between the first guide roller and the first discharge electrode and the distance between the second guide roller and the second discharge electrode can be kept the same, thereby making the adjusted device have the same roughening effect on the top and bottom of the plastic sheet coil.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The embodiment of the present application provides a device for roughening the surface of a plastic sheet, such as Figure 1-Figure 2 As shown, it includes a support platform 1, a first step-up transformer 6, a second step-up transformer 7, a controller 8, etc.

[0021] Specifically, a first discharge electrode 2 and a second guide roller 5 are provided on the top of the support platform 1, the discharge direction of the first discharge electrode 2 is toward the bottom of the first guide roller 4, the first guide roller 4 is spaced apart above the first discharge electrode 2, and the second discharge electrode 3 is spaced apart above the second guide roller 5, and the discharge direction of the second discharge electrode 3 is toward the top of the second guide roller 5; the first step-up transformer 6 is connected to the first discharge electrode 2; the second step-up transformer 7 is connected to the second discharge electrode 3; the controller 8 is connected to the first step-up transformer 6 and the second step-up transformer 7, and is used to control the opening and closing of the first step-up transformer 6 and the second step-up transformer 7.

[0022] In actual use, the plastic sheet coil that needs to be roughened is passed between the first guide roller 4 and the first discharge electrode 2, and then passed between the second guide roller 5 and the second discharge electrode 3, and the top surface of the plastic sheet coil is abutted against the first guide roller 4, and then the passed plastic sheet coil is connected to the driving roller, and the plastic sheet coil is pulled by the driving roller. At the same time, the controller 8 is controlled to start the first step-up transformer 6 and the second step-up transformer 7 to generate a high-voltage pulse current, so that the first discharge electrode 2 and the second discharge electrode 3 discharge to the top and bottom surfaces of the plastic sheet, so that both sides of the plastic sheet can be roughened at the same time.

[0023] For details, see Figure 2 A third guide roller 9 is provided on the side of the first discharge electrode 2 away from the second guide roller 5. The top of the third guide roller 9 is higher than the bottom of the first guide roller 4. When the plastic sheet roll passes through between the first guide roller 4 and the first discharge electrode 2 and is wound around the third guide roller 9, the top of the plastic sheet roll can be brought into contact with the first guide roller 4, separating the plastic sheet roll from the first discharge electrode 2. The winding path of the plastic sheet roll is as follows: Figure 1 For more details, see Figure 2 The first guide roller 4 and the second discharge electrode 3 are both fixed under a top plate 10 , and the top plate 10 is connected to the support platform 1 .

[0024] Preferably, see Figure 2 Both sides of the top plate are connected to the telescopic ends of two cylinders 11, which are fixed to the support platform 1. By adjusting the push-out distance of the telescopic ends of the cylinders 11, the distance between the first guide roller 4 and the first discharge electrode 2 and the distance between the second guide roller 5 and the second discharge electrode 3 can be adjusted simultaneously. Through this adjustment, the distance between the first guide roller 4 and the first discharge electrode 2 and the distance between the second guide roller 5 and the second discharge electrode 3 can be kept constant, thereby ensuring that the adjusted device has a consistent roughening effect on the top and bottom of the plastic sheet coil.

[0025] The above are only some of the embodiments listed in this application and are not intended to limit this application.
