Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a fabric coating mechanism. Background Technology

[0002] Fabric coating is a process that uniformly covers the surface of a fabric with a coating to improve its performance and appearance. Coating processes can be achieved through different methods, including knife coating, screen coating, and roller coating. Among these, roller coating is the most commonly used fabric surface coating equipment and is widely used.

[0003] Existing roller coating equipment for fabric processing has the following drawbacks: Although roller coating machines have the characteristics of high coating efficiency and uniform coating when coating the fabric surface, their special roller coating structure makes them only suitable for flat and large-sized substrates. During the coating process, they can only coat the entire substrate fabric. If the decorative coating on the fabric surface requires a segmented structure, the existing roller coating machine cannot be used, thus limiting its application scope. Therefore, we propose a fabric coating mechanism. Utility Model Content

[0004] The main objective of this invention is to provide a fabric coating mechanism. By adding a segmented component to the coating mechanism inside the roller coater when needed, the coating roller can coat the substrate surface in segments, thereby improving the flexibility of the roller coater and expanding its application range. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fabric coating mechanism includes a roller coater, a conveyor belt, and a coating mechanism. The roller coater has a horizontally arranged conveyor belt with a mounting base on its top. The mounting base houses the coating mechanism, which includes a coating roller, a metering roller, an end plate, a support plate, a bearing, a screw, a transfer roller, and a positioning nut. The mounting base has a coating roller on one side and a metering roller movably connected to the side of the mounting base near the coating roller. An end plate is inserted into the side of the mounting base, and a support plate is integrally formed on the side of the end plate and inserted into the bottom of the metering roller. Both sides of the top of the support plate are detachably connected to bearings, and a screw is movably connected between the bearings via bearings. A transfer roller is sleeved around the outer periphery of the screw, and positioning nuts are screwed onto both ends of the screw at the two ends of the transfer roller.

[0007] Furthermore, it also includes a recycling mechanism. The end plate surface is provided with a recycling mechanism, which includes a recycling cover, a scraper, a guide plate, and a confluence channel. The recycling cover is bolted to the end plate surface facing the coating roller, and the end of the recycling cover is provided with a scraper that fits against the surface of the coating roller. The inside of the recycling cover has guide plates integrally formed at an angle on both sides. The inside of the recycling cover is provided with a confluence channel located between the bottom ends of the guide plates. The end plate surface facing the coating roller has a recycling cover and scraper structure. After the position of the transfer roller is determined, a recycling cover of appropriate specifications is selected and installed on the end plate surface, so that after the recycling cover is installed in place, the scraper at its end can fit perfectly against the surface of the transfer roller. During the rotation of the transfer roller, the coating material on part of the coating roller surface is scraped off and moved with the transfer roller. When the coating material moves to the scraper position, it is scraped off by the scraper and flows into the inside of the recycling cover. Finally, it flows into the confluence channel along the guide plate and is discharged in a concentrated manner, realizing the recycling treatment of the coating material.

[0008] Furthermore, a feeding pipe is horizontally arranged inside the mounting base and connected to an external feeding device. The discharge end of the feeding pipe is located at the middle position between the top of the metering roller and the coating roller. The feeding pipe is connected to the external feeding device to transport the coating material into the mounting base and discharge it between the metering roller and the coating roller.

[0009] Furthermore, a slot is horizontally provided at the bottom of the inner wall of the mounting base, and an insert plate is integrally formed on the side of the end plate and inserted into the slot; when installing the end plate, the insert plate on its side is aligned with the slot and inserted, and the slot can limit the position of the insert plate, thereby restricting the position of the end plate.

[0010] Furthermore, a motor is fixed to the side of the end plate by bolts, and pulleys corresponding to the positions of the motor power output end and the screw end are installed, and a synchronous belt is connected between the pulleys; the motor power end and the screw end are provided with pulleys and the pulleys are connected by a synchronous belt. When the motor is running, its power end drives the screw to rotate through the synchronous belt and pulleys.

[0011] Furthermore, a recycling pipe is welded to the middle position inside the end plate, and the end of the manifold is connected to the end of the recycling pipe; the recycling pipe corresponds to the position of the manifold, so that the recycled coating entering the manifold can be discharged through the recycling pipe, and the end of the recycling pipe can be connected to the material cylinder.

[0012] Compared with the prior art, this utility model has the following beneficial effects: The conveyor belt inside the roller coating machine is used to transport the fabric. When the fabric passes through the inside of the mounting base, the coating roller and the metering roller cooperate to coat the fabric. When it is necessary to coat the entire substrate, the end plate is pulled out of the mounting base, and the coating roller operates normally to coat the fabric. When it is necessary to coat the fabric surface in sections, a transfer roller of appropriate specifications can be added at a suitable position on the outer periphery of the screw according to the coating requirements. After the transfer roller is positioned, positioning nuts are screwed into both ends to fix its position. The ends of the screw are connected to the bearings inside the shaft seat. The shaft seat is fixed to a suitable position on the top of the support plate by fasteners, so that after the end plate is inserted into the side of the mounting base, the surface of the transfer roller is exactly in contact with the surface of the coating roller. During the rotation of the coating roller, the parts that do not contact the transfer roller will normally coat the fabric substrate surface, while the coating at the position that contacts the transfer roller will be coated as the coating roller rotates to the next position. At the connection point with the transfer roller, the transfer roller scrapes off the coating material at the corresponding position on the surface of the coating roller, preventing the coating material from being applied to the fabric substrate surface. This transfer roller structure allows the coating roller to perform segmented coating on the fabric surface. The specifications and installation position of the transfer roller can be adjusted according to specific coating requirements, improving the flexibility of the roller coater and expanding its application range. A recovery hood and scraper structure are installed on the end plate surface facing the coating roller. Once the position of the transfer roller is determined, a recovery hood of appropriate specifications is installed on the end plate surface, ensuring that the scraper at its end fits precisely against the surface of the transfer roller. During the rotation of the transfer roller, the coating material at a certain position on the surface of the coating roller is scraped off and carried along with the transfer roller. When the coating material reaches the scraper position, it is scraped off and flows into the recovery hood, and finally flows along the guide plate into the confluence trough for centralized discharge, achieving coating material recycling.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, a fabric coating mechanism includes a roller coater 1, a conveyor belt 2, and a coating mechanism 3. The roller coater 1 has a horizontally arranged conveyor belt 2 with a mounting base 201 installed on its top. The mounting base 201 houses the coating mechanism 3, which includes a coating roller 301, a metering roller 302, an end plate 305, a support plate 307, a shaft seat 308, a bearing 309, a screw 310, a transfer roller 311, and a positioning nut 312. The coating roller 301 is mounted on one side of the mounting base 201. Inside the mounting base 201, near the coating roller 301, a metering roller 302 is movably connected. An end plate 305 is inserted into the side of the mounting base 201, and a support plate 307 is integrally formed on the side of the end plate 305 and inserted into the bottom of the metering roller 302. Both sides of the top of the support plate 307 are detachably connected to a bearing 308, and a screw 310 is movably connected between the bearings 309 inside the bearings 308. A transfer roller 311 is sleeved on the outer periphery of the screw 310, and a positioning nut 312 is screwed into the outer periphery of the screw 310 at both ends of the transfer roller 311.

[0020] The system also includes a recycling mechanism 4. The end plate 305 has a recycling mechanism 4 on its surface. The recycling mechanism 4 includes a recycling cover 402, a scraper 403, a guide plate 404, and a confluence groove 405. The recycling cover 402 is bolted to the side of the end plate 305 facing the coating roller 301, and a scraper 403 is attached to the end of the recycling cover 402 and fits onto the surface of the coating roller 301. Guide plates 404 are integrally formed obliquely on both sides inside the recycling cover 402. A confluence groove 405 is formed inside the recycling cover 402 between the bottom ends of the guide plates 404. A confluence groove 405 is provided on the side of the end plate 305 facing the coating roller 301. The structure of the recycling cover 402 and scraper 403 is as follows: After the position of the transfer roller 311 is determined, a recycling cover 402 of appropriate specifications is selected and installed on the surface of the end plate 305, so that after the recycling cover 402 is installed in place, the scraper 403 at its end can fit perfectly against the surface of the transfer roller 311. During the rotation of the transfer roller 311, the coating material on a part of the surface of the coating roller 301 is scraped off and moved with the transfer roller 311. When the coating material moves to the position of the scraper 403, it will be scraped off by the scraper 403 and flow into the inside of the recycling cover 402. Finally, it flows into the confluence trough 405 along the guide plate 404 and is discharged in a concentrated manner, thus realizing the recycling treatment of the coating material.

[0021] The mounting base 201 has a horizontally arranged feeding pipe 303 connected to an external feeding device. The discharge end of the feeding pipe 303 is located at the middle of the top of the metering roller 302 and the coating roller 301. The bottom of the inner wall of the mounting base 201 has a horizontally opened slot 304. The side of the end plate 305 has an integrally formed insert plate 306 that is inserted into the slot 304. The feeding pipe 303 is connected to the external feeding device to transport the coating into the mounting base 201 and discharge it between the metering roller 302 and the coating roller 301. When installing the end plate 305, the insert plate 306 on its side is aligned with the slot 304 and inserted. The slot 304 can limit the position of the insert plate 306, thereby restricting the position of the end plate 305.

[0022] The end plate 305 is bolted to a motor 313. The motor 313 and the screw 310 are both equipped with corresponding pulleys 314. The pulleys 314 are connected to each other by a synchronous belt 315. The motor 313 and the screw 310 are equipped with pulleys 314 and are connected by a synchronous belt 315. When the motor 313 is running, its power end drives the screw 310 to rotate through the synchronous belt 315 and the pulleys 314.

[0023] The end plate 305 has a recycling pipe 401 welded to the middle position inside. The end of the manifold 405 is connected to the end of the recycling pipe 401. The recycling pipe 401 is positioned corresponding to the manifold 405, so that the recycled coating entering the manifold 405 can be discharged through the recycling pipe 401. The end of the recycling pipe 401 can be connected to a pipeline to the material cylinder.

[0024] It should be noted that this utility model is a fabric coating mechanism. In use, the conveyor belt 2 inside the roller coater 1 is used to transport the fabric. When the fabric passes through the mounting base 201, the coating roller 301 and the metering roller 302 cooperate to coat the fabric. When it is necessary to coat the entire substrate, the end plate 305 is pulled out of the mounting base 201, and the coating roller 301 operates normally to coat the fabric. When it is necessary to perform segmented coating on the fabric surface, a transfer roller 311 of appropriate specifications can be added at a suitable position on the outer periphery of the screw 310 according to the coating requirements. After the material roller 311 is positioned, positioning nuts 312 are screwed into both ends to fix its position. The ends of the screw 310 are connected to the bearings 309 inside the bearing seat 308. The bearing seat 308 is fixed to the top of the support plate 307 at a suitable position by fasteners, so that after the end plate 305 is inserted into the side of the mounting base 201, the surface of the material roller 311 is exactly in contact with the surface of the coating roller 301. During the rotation of the coating roller 301, the parts that do not contact the material roller 311 will normally apply the coating to the surface of the fabric substrate, while the coating at the parts that contact the material roller 311 will be coated as the coating roller 301 rotates. When the coating roller 301 reaches the connection point with the transfer roller 311, the transfer roller 311 scrapes off the coating at the corresponding position on the surface of the coating roller 301, preventing the coating from being applied to the fabric substrate surface. Thus, the added transfer roller 311 structure allows the coating roller 301 to perform segmented coating on the fabric surface. The specifications and installation position of the transfer roller 311 can be adjusted according to specific coating requirements, improving the flexibility of the roller coating machine 1 and expanding its application range. A recovery cover 402 and a scraper 403 structure are provided on the end plate 305 facing the coating roller 301. When the transfer roller 311... Once the location is determined, a recycling hood 402 of appropriate specifications is installed on the surface of the end plate 305, so that the scraper 403 at the end of the recycling hood 402 can fit perfectly against the surface of the transfer roller 311. During the rotation of the transfer roller 311, the coating material on a portion of the surface of the coating roller 301 is scraped off and rotates with the transfer roller 311. When the coating material reaches the position of the scraper 403, it will be scraped off by the scraper 403 and flow into the inside of the recycling hood 402. Finally, it flows into the confluence trough 405 along the guide plate 404 and is discharged in a concentrated manner, thus realizing the recycling of the coating material.
