Description

Technical Field

[0001] This utility model relates to the field of filter membrane production technology, and to a corrosion-resistant composite filter membrane coating device. Background Technology

[0002] With the continuous development of the plastic products industry, films have been widely used. A film is a material with a thickness ranging from a fraction of a nanometer to a few micrometers, made of plastics, adhesives, rubber or other materials. There are many types of films, which can be divided into polyethylene film, polypropylene film, polyvinyl chloride film and polyester film, etc. In the process of film production, coating treatment is required.

[0003] Existing thin film coating devices have a relatively simple structure, but they have shortcomings in use:

[0004] 1. During operation, the coating device is prone to throwing the coating material out, causing some of the coating material to be thrown onto the filter membrane, which affects the coating quality;

[0005] 2. When using the coating device, it is not convenient to collect the dripping coating material for recycling, resulting in waste of coating material. Utility Model Content

[0006] This invention provides a corrosion-resistant composite filter membrane coating device to address the problems of existing technologies.

[0007] The objective of this utility model can be achieved through the following technical solution: A corrosion-resistant composite filter membrane coating device, comprising: an unwinding mechanism, a tensioning mechanism, a coating mechanism, a drying mechanism, and a rewinding mechanism arranged sequentially. The tensioning mechanism includes an adjusting column, a transmission assembly, and a tensioning roller. An adjusting groove is provided through the upper side of the adjusting column. The transmission assembly includes a reciprocating threaded rod rotatably disposed on both sides of the adjusting groove, a tensioning motor fixedly disposed on the upper end of the adjusting column, and a tensioning seat disposed on the reciprocating threaded rod. The upper end of the reciprocating threaded rod passes through the adjusting column and is connected to the output end of the tensioning motor. The tensioning roller is rotatably disposed on the tensioning seat. The coating mechanism includes a coating tank, a feeding roller and a coating roller rotatably disposed in the coating tank, and baffles disposed on both sides of the feeding roller. The coating roller is disposed on the upper side of the feeding roller and abuts against it.

[0008] In a further improvement, a rubber scraper is provided on the side end of the coating roller, and the rubber scraper abuts against the surface of the coating roller.

[0009] In a further improvement, the baffle is inclined downward toward the side away from the feeding roller and has a flow groove at its end.

[0010] In a further improvement, the rubber scraper is provided in two sets, which are symmetrically arranged on both sides of the coating roller.

[0011] In a further improvement, a guide groove is provided on the outside of the adjustment groove, and a guide block is provided on the outside of the clamping seat, with the guide block slidably disposed within the guide groove.

[0012] In a further improvement, the tensioning mechanism is provided in two sets, one set of which is located between the unwinding mechanism and the coating mechanism, and the other set of which is located between the drying mechanism and the winding mechanism.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In actual use, the filter membrane roll to be coated is first placed on the unwinding mechanism, and the corresponding unwinding motor is started to release the filter membrane. The membrane then passes through the tensioning mechanism, coating mechanism, and drying mechanism in sequence, and is finally wound up on the winding mechanism. The coating tank is filled with corrosion-resistant coating material, and the lower end of the feeding roller is in contact with the corrosion-resistant coating material. Since the surfaces of the feeding roller and the coating roller are in contact, the coating material is evenly coated on the filter membrane through the cooperation of the feeding roller and the coating roller during the coating process. At the same time, when the feeding roller rotates to feed the material, the baffles on both sides of the feeding roller can block the splashed coating material, so as to prevent the coating material from splashing onto the filter membrane during the coating process and affecting the coating efficiency of the filter membrane.

[0015] 2. This utility model uses a tensioning motor to drive the tensioning seat to rise and fall, thereby realizing the raising and lowering of the tensioning roller, which facilitates the adjustment of the tensioning roller to tension the filter membrane;

[0016] 3. In the coating process of this utility model, the paint dripping from the coating roller and scraped off by the rubber scraper flows through the inclined baffle to the flow channel and falls back into the coating tank, realizing the recycling of paint. Attached Figure Description

[0023] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.

[0024] Example 1

[0025] A corrosion-resistant composite filter membrane coating device includes: an unwinding mechanism 1, a tensioning mechanism 2, a coating mechanism 3, a drying mechanism 4, and a winding mechanism 5 arranged sequentially. The tensioning mechanism 2 includes an adjusting column 21, a transmission assembly 22, and a tensioning roller 23. An adjusting groove 211 is provided through the upper side of the adjusting column 21. The transmission assembly 22 includes a reciprocating threaded rod 221 rotatably disposed on both sides of the adjusting groove 211, a tensioning motor 222 fixedly disposed on the upper end of the adjusting column 21, and a tensioning seat 223 disposed on the reciprocating threaded rod 221. The upper end of the reciprocating threaded rod 221 passes through the adjusting column 21 and is drivenly connected to the output end of the tensioning motor 222. The tensioning roller 23 is rotatably disposed on the tensioning seat 223. The coating mechanism 3 includes a coating tank 31, a feeding roller 32 and a coating roller 33 rotatably disposed in the coating tank 31, and baffles 34 disposed on both sides of the feeding roller 32. The coating roller 33 is disposed on the upper side of the feeding roller 32 and abuts against it.

[0026] like Figures 1-3 As shown, in actual use, the filter membrane roll to be coated is first placed on the unwinding mechanism 1, and the corresponding unwinding motor is started to release the filter membrane. The membrane then passes through the tensioning mechanism 2, the coating mechanism 3, and the drying mechanism 4 in sequence, and is finally wound up on the winding mechanism 5. The coating tank 31 is filled with corrosion-resistant coating material, and the lower end of the feeding roller 32 is in contact with the corrosion-resistant coating material. Since the surfaces of the feeding roller 32 and the coating roller 33 are in contact, the coating material is evenly coated on the filter membrane through the cooperation of the feeding roller 32 and the coating roller 33 during the coating process. At the same time, when the feeding roller 32 rotates to feed the material, the baffles 34 located on both sides of the feeding roller 32 can block the splashed coating material, preventing the coating material from splashing onto the filter membrane during the coating process and affecting the coating efficiency.

[0027] The tensioning motor 222 drives the tensioning seat 223 to move up and down, thereby raising and lowering the tensioning roller 23, which facilitates the adjustment of the tensioning roller to tension the filter membrane.

[0028] As a further preferred embodiment, a rubber scraper 331 is provided on the side end of the coating roller 33, and the rubber scraper 331 abuts against the roller surface of the coating roller 33.

[0029] Specifically, during the coating process, the coating roller 33 is coated with a rubber scraper 331 to prevent the coating from piling up. At the same time, the thickness of the coating on the surface of the coating roller 33 is controlled by adjusting the angle between the rubber scraper 331 and the roller surface of the coating roller 33.

[0030] As a further preferred embodiment, the baffle 34 is inclined downward toward the side away from the feeding roller 32 and has a flow groove 341 at its end.

[0031] Specifically, during the coating process, the paint dripping from the coating roller 33 and scraped off by the rubber scraper 331 flows through the inclined baffle 34 to the flow channel 341 and falls back into the coating tank 31, thus realizing the recycling of the paint.

[0032] As a further preferred embodiment, the rubber scraper 331 is provided in two sets, and the two sets of rubber scrapers 331 are symmetrically arranged on both sides of the coating roller 33.

[0033] As a further preferred embodiment, a guide groove 2111 is provided on the outer side of the adjustment groove 211, and a guide block 2231 is provided on the outer side of the clamping seat 223. The guide block 2231 is slidably disposed in the guide groove 2111.

[0035] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
