A waste gas treatment device for adhesive tape production

Abstract

This utility model relates to the field of adhesive tape production technology, specifically a waste gas treatment device for adhesive tape production. The waste gas treatment device includes a coating machine, a clamping assembly on top of the coating machine, a fixing assembly on the front side of the clamping assembly, and a gas collection hood above the clamping assembly. A connecting pipe connects to the top of the gas collection hood. A hydraulic rod moves the clamping plates below the gas collection hood. Pulling the concave frame forward and rotating the handwheel moves the two clamping plates inward to clamp and fix the gas collection hood, thus achieving rapid installation. When the concave frame is released, the spring uses its own rebound force to move the concave frame backward through the connecting rod, causing the anti-slip pad to fit tightly against the handwheel. This prevents the clamping plates from loosening their grip on the gas collection hood due to handwheel rotation, ensuring the stability of the gas collection hood installation.

Description

Technical Field

[0001] This utility model relates to the field of tape production technology, specifically a waste gas treatment device for tape production. Background Technology

[0002] During the production of adhesive tape, the mixed adhesive is typically coated onto a film located on a coating machine to complete the adhesive application. During this process, the adhesive releases some toxic and harmful gases. Direct emission of these gases can easily pollute the atmosphere and damage the environment.

[0003] Chinese Patent Publication No. CN216857699U discloses a waste gas treatment device for adhesive tape production, belonging to the technical field of adhesive tape production. It includes a coating machine and a gas collection hood located at the top of the coating machine's adhesive application area. The device also includes a fixing mechanism mounted on the coating machine, comprising two clamping members and a moving component. The two clamping members are positioned opposite each other, with the gas collection hood located between them. The moving component drives the two clamping members to move towards or away from each other. This application facilitates ensuring the stability of the gas collection hood's position, thereby facilitating the stable collection of waste gas.

[0004] The existing technical solutions mentioned above have the following drawbacks: the gas collection hood is fixed by two sets of clamps, but the height of the two sets of clamps is adjusted by two sets of telescopic support rods. In actual use, it is difficult for workers to quickly adjust the telescopic length of the two sets of support rods to be consistent, thereby reducing the installation efficiency of the gas collection hood. In view of the above situation, technical innovation is carried out on the basis of the existing waste gas treatment equipment for tape production. Utility Model Content

[0005] The purpose of this invention is to provide a waste gas treatment device for tape production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste gas treatment device for tape production, comprising:

[0007] A coating machine, wherein a clamping assembly is mounted on the top of the coating machine, a fixing assembly is mounted on the front side of the clamping assembly, a gas collecting hood is mounted above the clamping assembly, a connecting pipe is connected to the top of the gas collecting hood, and an exhaust fan is installed inside the gas collecting hood.

[0008] Preferably, the clamping assembly includes a base, the top of which has two sets of first sliding grooves evenly distributed, each containing a second guide block. The top of the base also has a mounting groove containing a hydraulic rod. A mounting bracket is attached to the top of the telescopic end of the hydraulic rod. Two sets of second guide blocks are evenly distributed at the bottom of the mounting bracket. The top of the mounting bracket has a second sliding groove containing a bidirectional lead screw. An internally threaded slider is evenly screwed to the outer wall of the bidirectional lead screw. A clamping plate is attached to the top of the internally threaded slider. The front side of the bidirectional lead screw penetrates the front side of the mounting bracket and is connected to a handwheel. The top of the mounting bracket has two sets of guide grooves evenly distributed, and the bottom of the clamping plate has two sets of first guide blocks evenly distributed, each containing a guide groove.

[0009] Preferably, the base is located on top of the coating machine, and the gas collection hood is located between two sets of clamping plates.

[0010] Preferably, the fixing component includes a concave frame, two sets of connecting rods are evenly arranged on the rear side of the concave frame, a spring is provided on the rear side of the connecting rod, an anti-slip pad is provided on the front side of the inner wall of the concave frame, and a pull groove is provided through the top of the concave frame.

[0011] Preferably, the front side of the mounting bracket has two sets of mounting holes evenly spaced, the spring is fixedly disposed in the mounting holes, and the connecting rod is slidably disposed in the mounting holes.

[0012] Preferably, the concave frame is located on the front side of the mounting bracket, the concave frame is located on the outside of the handwheel, and the rear side of the anti-slip pad is in contact with the front side of the handwheel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model uses a hydraulic rod to move the clamping plate to the bottom of the gas collection hood, then pulls the concave frame forward and rotates the handwheel, which can move the two sets of clamping plates inward to clamp and fix the gas collection hood, thereby achieving the effect of quick installation of the gas collection hood.

[0015] When the concave frame is released, the spring uses its own rebound force to drive the concave frame backward through the connecting rod, thereby causing the anti-slip pad to fit tightly against the handwheel. This prevents the clamping plate from loosening its grip on the gas collection hood due to the rotation of the handwheel, thus ensuring the installation stability of the gas collection hood.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 A waste gas treatment device for tape production includes a coating machine 1, a clamping assembly on the top of the coating machine 1, a fixing assembly on the front side of the clamping assembly, a gas collection hood 13 above the clamping assembly, a connecting pipe 14 connected to the top of the gas collection hood 13, and an exhaust fan 15 fixedly installed inside the gas collection hood 13. The air inlet pipe of the waste gas purifier is connected to the connecting pipe 14. When the coating machine 1 applies adhesive to the tape, the exhaust fan 15 draws the gas emitted by the adhesive into the gas collection hood 13, and then inputs it into the waste gas purifier for purification through the connecting pipe 14.

[0022] The clamping assembly includes a base 11. Two sets of first sliding grooves are evenly distributed on the top of the base 11. Second guide blocks 19 are slidably disposed within the first sliding grooves. A mounting groove is also provided on the top of the base 11, and a hydraulic rod 18 is fixedly disposed within the mounting groove. A mounting frame 12 is fixedly disposed at the top of the telescopic end of the hydraulic rod 18. Two sets of second guide blocks 19 are evenly fixedly disposed at the bottom of the mounting frame 12. The hydraulic rod 18 drives the mounting frame 12 to move up and down, and the second guide blocks 19 assist in the stable up and down movement of the mounting frame 12. A second sliding groove is provided on the top of the mounting frame 12, and a bidirectional lead screw 21 is rotatably disposed within the second sliding groove. Two sets of internally threaded sliders 191 are evenly screwed onto the outer wall of the bidirectional lead screw 21. A clamping plate 17 is fixedly installed on the top of 91. The front side of the bidirectional screw 21 passes through the front side of the mounting frame 12 and is connected to a handwheel 2. Two sets of guide grooves are evenly opened on the top of the mounting frame 12. Two sets of first guide blocks 16 are evenly fixedly installed on the bottom of the clamping plate 17. The first guide blocks 16 are slidably installed in the guide grooves. The base 11 is fixedly installed on the top of the coating machine 1. The gas collection hood 13 is located between the two sets of clamping plates 17. Rotating the handwheel 2 drives the bidirectional screw 21 to rotate. The bidirectional screw 21 drives the two sets of internal thread sliders 191 to move inward, thereby driving the two sets of clamping plates 17 to move inward and clamp and fix the gas collection hood 13. The first guide blocks 16 assist the clamping plates 17 to slide stably.

[0023] The fixing assembly includes a concave frame 22, with two sets of connecting rods 23 evenly fixedly arranged on the rear side of the concave frame 22. A spring 24 is fixedly arranged on the rear side of the connecting rods 23. An anti-slip pad 25 is fixedly arranged on the front side of the inner wall of the concave frame 22. A groove is formed through the top of the concave frame 22. Two sets of mounting holes are evenly arranged on the front side of the mounting bracket 12. The spring 24 is fixedly arranged in the mounting holes, and the connecting rods 23 are slidably arranged in the mounting holes. The concave frame 22 is located on the front side of the mounting bracket 12, and is located near the handwheel 2. On the outside, the back side of the anti-slip pad 25 is in contact with the front side of the handwheel 2. By pulling the concave frame 22 forward through the pull groove, the anti-slip pad 25 is separated from the handwheel 2. At this time, the handwheel 2 can be rotated. When the concave frame 22 is released, the spring 24 uses its own rebound force to drive the concave frame 22 to move backward through the connecting rod 23, thereby driving the anti-slip pad 25 to fit tightly with the handwheel 2. This prevents the clamping plate 17 from loosening its clamping of the gas collection hood 13 due to the rotation of the handwheel 2, thus ensuring the installation stability of the gas collection hood 13.

[0024] Working principle: The hydraulic rod 18 drives the mounting bracket 12 to move up and down. When the mounting bracket 12 moves the clamping plate 17 to below the gas collection hood 13, the groove pulls the concave bracket 22 forward, causing the anti-slip pad 25 to separate from the handwheel 2. At this time, the handwheel 2 can be rotated, which drives the double-acting screw 21 to rotate. The double-acting screw 21 drives the two sets of internal threaded sliders 191 to move inward, thereby driving the two sets of clamping plates 17 to move inward and clamp and fix the gas collection hood 13. When the concave bracket 22 is released, the spring 24 releases its pressure. The self-rebound force drives the concave frame 22 to move backward through the connecting rod 23, thereby causing the anti-slip pad 25 to fit tightly with the handwheel 2. This prevents the clamping plate 17 from loosening its grip on the gas collection hood 13 due to the rotation of the handwheel 2, thus ensuring the installation stability of the gas collection hood 13. The air inlet pipe of the exhaust gas purifier is connected to the connecting pipe 14. When the coating machine 1 applies adhesive to the tape, the exhaust fan 15 draws the gas emitted by the adhesive into the gas collection hood 13, and then inputs it into the exhaust gas purifier for purification through the connecting pipe 14.
