Description

Technical Field

[0001] This utility model relates to the technical field of mesh fabric coating preparation device, and in particular to a mesh fabric coating preparation device. Background Technology

[0002] The mesh fabric coating preparation device is a specialized piece of equipment used to coat the surface of mesh fabric. It is designed to uniformly coat the mesh fabric with specific coatings to improve its performance, such as enhancing its waterproofness, fire resistance, abrasion resistance, or changing its appearance. It is widely used in fields such as construction, industrial filtration, and aerospace.

[0003] In the process of coating mesh, in order to ensure the uniformity of coating, a scraper is usually used to remove excess paint. However, most existing mesh coating preparation devices lack an effective recycling structure for the paint scraped off by the scraper. The paint scraped off by the scraper is often directly treated as waste, resulting in a large amount of paint waste. Since the amount of mesh to be coated is large and in the continuous production process, the amount of such waste is considerable, which leads to an increase in production costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mesh fabric coating preparation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mesh fabric coating preparation device, comprising a coating frame, two conveying rollers rotatably connected to the coating frame, two guide rollers rotatably connected to the coating frame, two coating rollers rotatably connected to the coating frame, two spray pipes fixedly connected to the coating frame, each spray pipe having a nozzle, two first gears fixedly connected to one end of each guide roller, the two first gears meshing with each other, a second gear fixedly connected to one end of each guide roller and coating roller, corresponding two second gears meshing with each other, a first synchronous pulley fixedly connected to each of the two second gears, the two first synchronous pulleys being driven by a first synchronous belt, a second synchronous pulley fixedly connected to one of the first gears and one of the second gears, the two second synchronous pulleys being driven by a second synchronous belt, a first motor fixedly connected to the coating frame, one of the second gears being driven to rotate by the first motor, a recycling structure provided on the coating frame, the recycling structure mainly consisting of two scrapers, both scrapers being fixedly connected to the coating frame, and collection grooves respectively opened on the inner walls of both sides of the coating frame.

[0006] The effect achieved by the above components is as follows: the output end of the first motor is connected to the second gear through a reducer and a coupling. The model of the first motor is Y2-160m1-8. Starting the first motor can drive one of the second gears to rotate, causing one guide roller to rotate. Under the action of multiple first and second gears and the first and second synchronous belts, the two conveyor rollers rotate synchronously in opposite directions, thereby driving the mesh cloth forward. The two guide rollers guide the mesh cloth, and then the coating adhesive is sprayed onto the coating roller through two spray pipes. When the mesh cloth passes through the coating roller, the two coating rollers coat the upper and lower sides of the mesh cloth respectively. When the mesh cloth passes through two scrapers, the two scrapers can scrape off the excess coating on the mesh cloth. Then the coating will enter the collection tanks on both sides through the guide grooves on the scrapers, thereby avoiding the situation where the amount of coating on the mesh cloth is large and the amount of waste accumulated during continuous production is considerable, which would increase the production cost.

[0007] Preferably, the coating rack has a connecting groove, and the two collection grooves are connected through the connecting groove.

[0008] The effect achieved by the above components is that the paint collected in the collection tank can be gathered into the connecting tank for centralized processing.

[0011] Preferably, the collection tank is provided with two mounting blocks, and a filter plate is fixedly connected to both mounting blocks.

Under the action of multiple first and second gears and the first and second synchronous belts, the two conveyor rollers rotate synchronously in opposite directions, thereby driving the mesh cloth forward. The two guide rollers guide the mesh cloth, and then the coating adhesive is sprayed onto the coating roller through two spray pipes. When the mesh cloth passes through the coating roller, the two coating rollers coat the upper and lower surfaces of the mesh cloth respectively. When the mesh cloth passes through two scrapers, the two scrapers can scrape off the excess coating on the mesh cloth. Then the coating will enter the collection tanks on both sides through the guide grooves on the scrapers, thereby avoiding the situation where the amount of coating on the mesh cloth is large and the amount of waste accumulated during continuous production is considerable, which would increase the production cost.

[0029] Example 1, such as Figures 1 to 3 As shown, a mesh fabric coating preparation device includes a coating frame 1, two conveying rollers 2 rotatably connected to the coating frame 1, two guide rollers 3 rotatably connected to the coating frame 1, two coating rollers 4 rotatably connected to the coating frame 1, two spray pipes 5 fixedly connected to the coating frame 1, each spray pipe 5 having a nozzle, two first gears 6 fixedly connected to one end of each guide roller 3, the two first gears 6 meshing with each other, a second gear 7 fixedly connected to one end of each guide roller 3 and coating roller 4, corresponding two second gears 7 meshing with each other, a first synchronous pulley 8 fixedly connected to each of the two second gears 7, the two first synchronous pulleys 8 being driven by a first synchronous belt 10, a second synchronous pulley 11 fixedly connected to one of the first gears 6 and one of the second gears 7, the two second synchronous pulleys 11 being driven by a second synchronous belt 12, a first motor 13 fixedly connected to the coating frame 1, one second gear 7 being driven to rotate by the first motor 13.

[0030] Reference Figures 1 to 6The coating rack 1 is equipped with a recycling structure 9, which mainly consists of two scrapers 91, both of which are fixedly connected to the coating rack 1. Collection grooves 92 are respectively opened on the inner walls of both sides of the coating rack 1. The output end of the first motor 13 is connected to the second gear 7 through a reducer and a coupling. The model of the first motor 13 is Y2-160m1-8. Starting the first motor 13 can drive one of the second gears 7 to rotate, causing one guide roller 3 to rotate. Multiple first gears 6 and second gears 7, as well as the first synchronous belt 10 and the second... Under the action of the synchronous belt 12, the two conveyor rollers 2 rotate synchronously in opposite directions, thereby driving the mesh fabric forward. The two guide rollers 3 guide the mesh fabric, and then the coating adhesive is sprayed onto the coating rollers 4 through the two spray pipes 5. When the mesh fabric passes through the coating rollers 4, the two coating rollers 4 coat the upper and lower surfaces of the mesh fabric respectively. When the mesh fabric passes through the two scrapers 91, the two scrapers 91 can scrape off the excess coating on the mesh fabric. Then the coating will enter the collection tanks 92 on both sides through the guide grooves on the scrapers 91, thereby avoiding the coating of the mesh fabric being damaged. Due to the large coating volume and the considerable accumulated waste during continuous production, production costs have increased. To address this, a connecting groove 93 is provided in the coating rack 1, through which two collection tanks 92 are connected. The coating collected in the collection tanks 92 can be gathered in the connecting groove 93 for centralized processing. A liquid pump 94 is fixedly connected to one side of the coating rack 1. An inlet pipe 95 is fixedly connected to the input end of the liquid pump 94, and the inlet pipe 95 is connected to the connecting groove 93. A second outlet pipe 97 is fixedly connected to the output end of the liquid pump 94. A first outlet pipe 96 is fixedly connected to the outlet pipe 97. The first outlet pipe 96 and the second outlet pipe 97 are respectively fixedly connected to two spray pipes 5. When the liquid pump 94 is started, the liquid pump 94 can pump the paint collected in the connecting tank 93 through the inlet pipe 95 to the first outlet pipe 96 and the second outlet pipe 97, and then enter the corresponding spray pipes 5. Two mounting blocks 98 are provided in the collection tank 92. A filter plate 99 is fixedly connected to the two mounting blocks 98. The filter plate 99 can filter the paint to prevent impurities from entering the liquid pump 94 and affecting the coating effect.

[0031] Reference Figures 1 to 6The collection tank 92 has sliding grooves 910 on both sides, which are slidably connected to the mounting block 98.

The collection tank 92 has rectangular grooves 911 on both sides, and springs 912 are fixedly connected to the inner wall of the rectangular grooves 911. One end of the spring 912 is fixedly connected to the filter plate 99. When the filter plate 99 is slid upward, the two springs 912 are compressed and contracted. Then, when the filter plate 99 is released, it moves under the elastic force of the springs 912. The coating frame 1 is rotatably connected to both sides. There is a cam 913. When the cam 913 is rotated, when the protruding part of the cam 913 contacts the filter plate 99, it will push the filter plate 99 to slide upward. When the protruding part rotates to a position away from the filter plate 99, the filter plate 99 will move downward, making the operation more convenient. The two sides of the coating frame 1 are respectively fixedly connected to the second motor 914. The cam 913 is driven to rotate by the second motor 914. The output end of the second motor 914 is connected to the cam 913 through a reducer and a coupling. The model of the second motor 914 is 28BYJ-48. Then, starting the second motor 914 can drive the cam 913 to rotate.

Under the action of multiple first gears 6 and second gears 7, as well as the first synchronous belt 10 and second synchronous belt 12, the two conveyor rollers 2 rotate synchronously in opposite directions, thereby driving the mesh fabric forward. The two guide rollers 3 guide the mesh fabric, and then the coating adhesive is sprayed onto the coating roller 4 through two spray pipes 5. When the mesh fabric passes through the coating roller 4, the two coating rollers 4 coat the upper and lower surfaces of the mesh fabric respectively. When the mesh fabric passes through two scrapers 91, the two scrapers 91 can scrape off the excess coating on the mesh fabric. Then the coating will enter the collection tanks 92 on both sides through the guide grooves on the scrapers 91, thus avoiding the situation where the amount of coating on the mesh fabric is large and the amount of waste accumulated during continuous production is considerable, which would increase the production cost. The coating collected in the collection tank 92 is... The coating material can be collected in the connecting tank 93 for centralized processing. The liquid pump 94 is started, pumping the coating material collected in the connecting tank 93 through the inlet pipe 95 to the first outlet pipe 96 and the second outlet pipe 97, and then into the corresponding spray pipe 5. The filter plate 99 filters the coating material, preventing impurities from entering the liquid pump 94 and affecting the coating effect.

When the filter plate 99 is slid upwards, it compresses two springs 912 to contract, and then releases... When the filter plate 99 is opened, it moves under the elastic force of the spring 912. When the cam 913 is rotated, the protruding part of the cam 913 contacts the filter plate 99, which pushes the filter plate 99 to slide upward. When the protruding part rotates to a position away from the filter plate 99, the filter plate 99 moves downward, making the operation more convenient. The output end of the second motor 914 is connected to the cam 913 through a reducer and a coupling. The model of the second motor 914 is 28BYJ-48. Then, starting the second motor 914 can drive the cam 913 to rotate.
