Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surface coating of silica gel tape, in particular to a coating equipment for polyester film silica gel tape production. BACKGROUND

[0002] The silica gel tape is a functional tape made of silicone rubber as the core material, and has a unique molecular structure. The silica gel tape is mainly composed of silicone rubber (raw rubber + fillers such as silica, vulcanizing agent, coupling agent), optional substrate (PET, PI film, glass fiber cloth, etc.), and release layer (silicone oil paper).

[0003] The silica gel tape has the following steps in the production process:

[0004] Substrate unwinding: the PET, PI and other substrates are stably transported through the tension control system;

[0005] Glue coating: the silicone rubber glue (liquid or hot melt state) is transferred to the substrate by using a coating head (such as comma doctor blade, micro concave roller, and slit die);

[0006] Vulcanization and curing: the silicone rubber is crosslinked into a solid glue layer through high temperature (150-200℃) or UV light curing;

[0007] Winding and slitting: the coated substrate is wound and slitted into a specified width of finished tape;

[0008] The above silica gel tape has the following steps in the production process: the glue coating is a crucial part, and the roller coating machine is used to coat the surface of the tape. The coating roller is in contact with the coating material, and the coating is applied to the silica gel tape along with the movement of the coating roller. In this process, the comma doctor blade controls the coating thickness of the coating roller.

[0009] In the use process of the above existing technology, the comma doctor blade is in a state of constantly scraping and blocking the coating material, so that the thickness of the coating roller coated on the tape is uniform. If the glue thickness on the tape needs to be changed, the gap between the blade edge of the comma doctor blade and the coating roller needs to be changed, so that the comma doctor blade controls the coating thickness on the surface of the coating roller. However, in the long-term use process of the coating roller, impurities (such as lumps and metal debris) in the coating material or dust particles (>50μm) in the environment are embedded in the gap between the doctor blade and the substrate, forming "abrasive" and accelerating the wear of the comma doctor blade. When the comma doctor blade is worn, the coating surface on the coating roller becomes uneven, causing strip-shaped protrusions or strip-shaped gaps and other stripe defects on the coating layer on the surface of the silica gel tape. This makes the workers have to stop the machine and replace the comma doctor blade, which affects the coating efficiency.

[0010] To solve the above problems, the application provides a coating equipment for polyester film silica gel tape production. SUMMARY

[0051] A comma doctor blade 17 is rotatably connected inside the machine body 1, and the blade of the comma doctor blade 17 has a gap with the coating roller 15. One end of the comma doctor blade 17 is connected with a driving motor 171 arranged outside the machine body 1. A fan-shaped groove 172 is formed at the end of the comma doctor blade 17 away from the driving motor 171, and a rotating rod 173 is rotatably connected inside the fan-shaped groove 172. A cleaning blade 174 is arranged at one end of the rotating rod 173 on the surface of the comma doctor blade 17, and the rotating rod 173 is driven by the motor;

[0052] A back roller 18 is arranged inside the machine body 1, and the horizontal height of the back roller 18 is higher than that of the pressing roller 14;

[0053] An optical sensor 19 is arranged inside the machine body 1 and located between the comma doctor blade 17 and the back roller 18;

[0054] A drying box 3 is located at the upper end inside the machine body 1, and the drying box 3 is located between the back roller 18 and the winding roller 12;

[0055] Two shaft wheels 111 are arranged between the back roller 18 and the coating roller 15, and rubber belts 112 are arranged outside the two shaft wheels 111. One of the two shaft wheels 111 is rotatably driven by a micro motor, the optical sensor 19 is located between the comma doctor blade 17 and the rubber belt 112, and the surface of the rubber belt 112 is treated to be smooth.

[0056] The specific working process is as follows:

[0057] When coating the silicone tape, the staff first installs the silicone tape, and the drive device 2 on the winding roller 12 and the unwinding roller 11 is connected by a fixed plate, and a telescopic cylinder is set between the fixed plate and the outer side of the machine body 1, so that when the telescopic cylinder is extended, the winding roller 12 and the drive device 2 corresponding to the winding roller 12 are pushed out of the machine body 1, and the unwinding roller 11 and the drive device 2 corresponding to the unwinding roller 11 are pushed out of the machine body 1; then the silicone tape roll to be coated is installed on the unwinding roller 11, and the unwinding roller 11 and the machine body 1 are detachably connected, so that the silicone tape roll is installed on the unwinding roller 11, and then one end of the silicone tape is passed over the upper side of the guide roller 13, and the guide roller 13 is located on the lower side of the silicone tape, so that the guide roller 1 3 pairs of silicone belt supports, then the silicone belt is passed through the gap between the pressure roller 14 and the coating roller 15, and the lower side of the pressure roller 14 squeezes the upper side of the silicone belt (the pressure roller 14 is driven by a motor provided on one side of the machine body 1), while the coating roller 15 is located on the lower side of the silicone belt, and the coating roller 15 does not contact the lower side of the silicone belt, and there is a gap between the two, the size of the gap determines the thickness of the coating on the silicone belt; then the silicone belt passes through the gap between the pressure roller 14 and the coating roller 15, so that the outer ring of the silicone belt is tightly attached to the back roller 18, specifically, the silicone belt contacts the side of the back roller 18 away from the unwinding roller 11, and then the silicone belt passes through the inside of the drying box 3 and is wound around the winding roller 12;

[0058] The staff starts the coating device, the unwinding roller 11 rotates to unwind the silicone tape, and the winding roller 12 rotates to rewind the silicone tape. The unwinding roller 11 and the rewinding roller 12 are rotated by the driving device 2, and the driving device 2 is driven by a motor. In the process of unwinding the unwinding roller 11 and rewinding the rewinding roller 12, the guide roller 13 guides the silicone tape (the guide roller 13 is driven by the motor arranged on the outside of the machine body 1), and at the same time, the guide roller 13 tensions the silicone tape between the rewinding roller 12 and the pressure roller 14. Then the silicone tape moves to the position between the pressure roller 14 and the coating roller 15. During the process, the coating roller 15 is rotated by the driving device 2, and one side of the coating roller 15 is located in the storage box 16, so that the coating roller 15 is combined with the coating in the storage box 16, and the coating adheres to the surface of the coating roller 15. As the coating roller 15 rotates, the coating on the coating roller 15 contacts the lower side of the silicone tape on the lower side of the pressure roller 14, so that the coating roller 15 bonds the coating to the lower surface of the silicone tape;

[0059] In the process of rotating the coating roller 15, the comma doctor blade 17 is located on one side of the coating roller 15, and there is a gap between the comma doctor blade 17 and the outer side of the coating roller 15, so that after the coating roller 15 carries the paint out of the paint storage tank 16, the comma doctor blade 17 removes the excess paint on the outer side of the coating roller 15, realizing the control of the thickness of the paint on the surface of the coating roller 15; and the upper part of the comma doctor blade 17 is provided with a fan-shaped groove 172, the inside of the fan-shaped groove 172 is rotationally connected with a rotating rod 173, the end of the rotating rod 173 is provided with a cleaning blade 174, and the cutting edge of the cleaning blade 174 coincides with the cutting edge of the comma doctor blade 17; and if the cutting edge of the comma doctor blade 17 coincides with the cutting edge of the cleaning blade 174, the gap between the cutting edge of the comma doctor blade 17 and the cutting edge of the cleaning blade 174 is the smallest; when it is necessary to increase the thickness of the paint on the silica gel tape, the staff controls the drive motor 171 at the end of the comma doctor blade 17 which is not provided with the fan-shaped groove 172 to rotate counterclockwise, so that the drive motor 171 drives the comma doctor blade 17 and the cleaning blade 174 to rotate counterclockwise, so that the distance between the cutting edge of the comma doctor blade 17 and the cleaning blade 174 and the surface of the coating roller 15 increases, the thickness of the paint carried by the surface of the coating roller 15 is increased, and the thickness of the paint on the coating roller 15 coated on the surface of the silica gel tape is increased; in the initial state, the cutting edge of the cleaning blade 174 does not coincide with the cutting edge of the comma doctor blade 17, so that when the thickness of the paint on the surface of the coating roller 15 is quantified, the excess paint on the coating roller 15 is first removed by the cutting edge of the comma doctor blade 17;

[0060] In the process of coating the surface of the silica gel tape, the optical sensor 19 is arranged on the inner side of the machine body 1, and the optical sensor 19 is located between the back roller 18 and the coating roller 15, and the optical sensor 19 is located on the lower side of the silica gel tape, so that when the silica gel tape coated by the coating roller 15 moves towards the back roller 18, the optical sensor 19 monitors the lower side of the coated silica gel tape in real time, and in the monitoring process, if it is found that the surface of the coated silica gel tape has strip-shaped defects due to the wear of the comma doctor blade 17, since the cutting edge of the cleaning blade 174 does not coincide with the cutting edge of the comma doctor blade 17 in the initial state, it can be judged that the cutting edge of the comma doctor blade 17 is worn during long-term use, at this time the staff can control the micro motor inside the fan-shaped groove 172 to rotate clockwise, and the rotating rod 173 drives the cleaning blade 174 to rotate clockwise, until the cutting edge of the cleaning blade 174 coincides with the cutting edge of the comma doctor blade 17, so that the cleaning blade 174 covers the lower end of the comma doctor blade 17, so that when the cutting edge of the cleaning blade 174 quantifies the thickness of the paint on the coating roller 15, it is not necessary to stop and replace the comma doctor blade 17, which can solve the problem of strip-shaped defects in the coating of the silica gel roll;

[0061] In the above process, two shaft wheels 111 are arranged between the back roller 18 and the coating roller 15, and a rubber belt 112 is sleeved on the two shaft wheels 111. The surface of the rubber belt 112 is treated to be smooth. The two shaft wheels 111 and the rubber belt 112 are located below the silicone belt between the back roller 18 and the coating roller 15. The gap between the rubber belt 112 and the silicone belt is the same as the distance between the coating roller 15 and the comma doctor blade 17. When the silicone belt moves towards the back roller 18 (the back roller 18 is driven by the motor arranged on one side of the machine body 1), the surface of the rubber belt 112 on the upper side contacts the paint coated on the lower side of the silicone belt. At the same time, the rubber belt 112 is driven to rotate counterclockwise by the two shaft wheels 111, so that the surface of the rubber belt 112 smooths the paint coated on the lower side of the silicone belt, thereby avoiding damage to the comma doctor blade 17 and the uneven coating on the lower side of the silicone belt. The paint has fluidity. After the coating roller 15 coats the paint on the lower side of the silicone belt, the paint will flow to some extent on the lower side of the silicone belt, causing uneven coating on the lower end of the silicone belt. At this time, when the silicone belt moves above the rubber belt 112, the rubber belt 112 smooths the paint on the lower end of the silicone belt, thereby avoiding this problem.

[0062] When the silicone belt coated with paint passes through the back roller 18, the silicone belt coated with paint enters the drying box 3, which is an existing drying device. After the silicone belt coated with paint moves out of the drying box 3, the paint on the silicone belt is cross-linked and cured. Then, the silicone belt coated with paint is pulled by the winding roller 12, so that the silicone belt coated with paint is wound on the winding roller 12. After winding is completed, the winding roller 12 is detachably connected to the machine body 1, so that the staff can remove the silicone roll wound on the winding roller 12.

[0063] Embodiment two:

[0064] As shown in Figures 2 to 10 The inner side wall of the machine body 1 is provided with a sliding groove 113. The sliding groove 113 is slidably connected with a sliding plate 114. The lower side of the sliding plate 114 is provided with two support plates 115. The two support plates 115 are rotatably connected with an adjusting roller 116. The adjusting roller 116 is located above the rubber belt 112 and has a gap with the rubber belt 112. The output shaft of the driving motor 171 is provided with an adjusting rod 117. The upper end of the adjusting rod 117 is provided with an arc-shaped plate 118. The arc-shaped plate 118 contacts the lower side of the sliding plate 114.

[0065] The specific working process is as follows:

[0066] By providing a slide groove 113 on the inner side of the machine body 1, a sliding plate 114 is slidably connected inside the slide groove 113, so that support plates 115 are provided at both ends of the lower side of the sliding plate 114, and an adjusting roller 116 is rotatably connected between the support plates 115; so that the adjusting roller 116 is located above the rubber belt 112, and there is a gap between the adjusting roller 116 and the rubber belt 112 bracket; when the silicone belt moves out from between the pressure roller 14 and the coating roller 15, the silicone belt passes through the position between the adjusting roller 116 and the rubber belt 112, and at the same time, the adjusting roller 116 squeezes the lower side of the silicone belt. In the initial state, when the sliding plate 114 is located at the lowest end of the slide groove 113, the adjusting roller 116 is at the lowest initial horizontal height. At this time, the adjusting roller 116 squeezes the silicone belt so that the distance between the squeezed part of the silicone belt and the rubber belt 112 is the minimum distance between the comma scraper 17 and the coating roller 15;

[0067] When the staff needs to increase the coating thickness of the silicone belt according to different requirements, the staff controls the drive motor 171 on one side of the comma scraper 17 to rotate, and the output shaft of the drive motor 171 drives the comma scraper 17 to rotate counterclockwise. When the comma scraper 17 rotates counterclockwise, the rotating rod 173 and the cleaning blade 174 are driven to rotate counterclockwise synchronously. At this time, the gap between the blade of the comma scraper 17 and the coating roller 15 becomes larger, so that the thickness of the coating on the coating roller 15 increases when it passes through the comma scraper 17.

[0068] And when the driving motor 171 on one side of the comma scraper 17 rotates, the adjusting rod 117 set on the output shaft of the driving motor 171 rotates counterclockwise synchronously, and the arc plate 118 at the upper end of the adjusting rod 117 rotates, and the arc plate 118 pushes the lower side of the sliding plate 114, so that the sliding plate 114 slides upward inside the slide groove 113. During the process, the sliding plate 114 drives the adjusting roller 116 to move upward. During the upward movement of the adjusting roller 116, the silicone belt located on the lower side of the adjusting roller 116 moves upward synchronously, so that the gap between the silicone belt and the rubber belt 112 becomes larger, and then when the gap between the comma scraper 17 and the coating roller 15 becomes larger, the gap between the lower side of the silicone belt and the rubber belt 112 becomes larger synchronously, so that the rubber belt 112 can smooth coatings of different thicknesses, thereby improving the coating effect of the silicone belt.

[0069] Example 3:

[0070] like Figures 1 to 10 As shown; the interior of the body 1 is provided with a mounting plate 4, the upper end of the mounting plate 4 is provided with a mounting groove 41, the lower inner wall of the mounting groove 41 is provided with a cleaning knife 42, the upper end of the cleaning knife 42 contacts the lower end of the lower portion of the rubber belt 112;

[0071] The interior of the mounting groove 41 is rotatably connected to a roller 43, and the roller 43 is located between the rubber belt 112. Specifically, the rubber belt 112 at the bottom is located between the roller 43 and the cleaning blade 42.

[0072] The interior of the roller 43 is a heat conducting wire, which is electrically heated.

[0073] The specific workflow is as follows:

[0074] A mounting plate 4 is provided inside the body 1, and a mounting groove 41 is provided at the upper end of the mounting plate 4, and a cleaning knife 42 is provided on the lower inner wall of the mounting groove 41, so that the upper end of the cleaning knife 42 contacts the lower end of the lower part of the rubber belt 112; on the basis of the above embodiment, when the rubber belt 112 rotates, the surface of the upper part of the rubber belt 112 will smooth the paint on the lower side of the silicone belt above it, and then the part of the rubber belt 112 that smoothes the lower side of the silicone belt will move to the upper end of the cleaning knife 42. During the process, the surface of the rubber belt 112 contacts the upper end of the cleaning knife 42, and the cleaning knife 42 scrapes off the paint adhered to the surface of the rubber belt 112, thereby preventing the paint from adhering to the surface of the rubber belt 112, resulting in the problem that the paint on the lower side of the silicone belt is affected by the paint adhered to the surface of the rubber belt 112 when the surface of the silicone belt is smoothed, resulting in strip defects on the lower side of the silicone belt;

[0075] The roller 43 is connected to the rubber belt 112 by rotating it in the mounting groove 41, so that the roller 43 is located inside the rubber belt 112. When the rubber belt 112 rotates, the rubber belt 112 moves between the roller 43 and the cleaning knife 42. During this process, the roller 43 limits the position of the rubber belt 112, so as to avoid the problem that the surface of the rubber belt 112 and the cleaning knife 42 are not in close contact during the movement of the rubber belt 112, and the paint adhered to the surface of the rubber belt 112 cannot be cleaned. At the same time, the heat conducting wire inside the roller 43 makes the roller When roller 43 guides and contacts the inner side of the rubber belt 112, the heat conducting wire transfers the temperature to the outer side of roller 43, and then roller 43 transfers the temperature to the surface of the rubber belt 112, so that the temperature of the surface of the rubber belt 112 increases, and then the temperature of the paint bonded to the surface of the rubber belt 112 increases, which in turn causes the viscosity of the paint bonded to the surface of the rubber belt 112 to decrease, making it easier to be scraped off by the cleaning knife 42, thereby improving the cleaning effect of the surface of the rubber belt 112, and thereby improving the smoothing effect of the rubber belt 112 on the paint layer on the lower side of the silicone belt.

[0076] Example 4:

[0077] like Figures 2 to 10 As shown; the mounting plate 4 is connected to the inner side of the body 1 by sliding up and down, and a tension spring is provided between the mounting plate 4 and the body 1. In the initial state, the tension spring is in a tensioned state;

[0078] The lower inner wall of the installation groove 41 is inclined, and the lower inner wall of the installation groove 41 is provided with a heating plate 44, and the cleaning knife 42 is arranged on the heating plate 44.

[0079] The specific working process is as follows:
