The device includes a coating mechanism positioned on top of a base platform and located between a conveying mechanism and a dryer. The coating mechanism comprises a storage tank and a coating assembly. This invention achieves this by enabling the coating roller to vibrate while applying coating to the surface of the polymer release film, followed by scraping the coating with a comma-shaped scraper.

Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, specifically to an intelligent coating device and method for processing polymer release films. Background Technology

[0002] Coating machines are mainly used to uniformly coat coatings, adhesives or other functional materials onto the surface of a substrate. The core purpose of coating polymer release films is to endow them with specific functions through surface treatment to meet the needs of different industrial scenarios.

[0003] CN119634147B discloses a multi-stage drying coating machine, which aims to optimize the distribution of coating through the high-frequency vibration of a comma-shaped doctor blade. The vibration effectively promotes the contact and penetration between coating molecules and the coating substrate, making the coating adhere more firmly to the substrate. This not only improves the uniformity of the coating but also enhances its adhesion, thereby improving the overall coating effect of the coating machine.

[0004] Based on existing technologies, the following problems exist:

[0005] In the process of improving coating adhesion through comma-shaped doctor blade vibration, the coating is usually in a fluid state, and the doctor blade is used for cleaning after coating. The vibration generated during the comma-shaped doctor blade vibration is within the coating, causing wavy patterns on the coating surface, which affects the smoothness of the coating. In addition, the film substrate usually has a certain degree of elasticity, while the doctor blade usually cleans from one side of the coating roller, and the film substrate has no support. During the vibration of the doctor blade, the film is subjected to force and undergoes deformation and displacement, resulting in limited effect on improving adhesion. To solve the above problems, an intelligent coating device and method based on polymer release film processing is proposed. Summary of the Invention

The outer wall of the second bearing seat is fixedly sleeved with an air bladder. The top of the air bladder is reserved with a connection port for connecting the pipeline.

[0024] The sealing cover has its inner wall slidably connected to the outer wall of the second mounting sleeve, and the sliding part is designed with dynamic sealing. The outer wall of the sealing cover is fixedly connected to the outer side of the second bearing seat.

[0025] Furthermore, the resonant assembly also includes:

[0026] The vibrating rod is fixedly installed at the bottom of the outer wall of the air bag and slidably connected to the inner wall of the storage box. While limiting the position of the vibrating rod, it also allows the vibrating rod to have space to vibrate. A frame is fixedly installed at the bottom of the vibrating rod.

[0027] The first through groove is opened on the side wall of the vibrating rod.

[0028] Furthermore, the actuating component includes:

[0029] The first rod is fitted inside the vibrating rod. A limiting groove is opened at the upper end of the vibrating rod.

[0034] The push plate is fixedly installed at one end of the third rod body located inside the storage box. The bottom of the push plate is in contact with the bottom of the inner wall of the storage box, and the side wall of the push plate is provided with spaced guide holes.

[0035] A fixing component is fixed to the outer wall of the storage box and sleeved on the side wall of the third rod. A baffle is fixed to one end of the third rod outside the storage box. A second spring is sleeved on the side wall of the third rod and the second spring is located between the fixing component and the baffle.

[0036] Furthermore, the top of the storage box is provided with a guiding mechanism for guiding the winding of the polymer release film so that the polymer release film can be coated with paint by the coating roller, and a comma scraper mechanism for scraping the paint is provided on one side of the storage box.

[0037] This invention also provides a method for using an intelligent coating device for polymer release film processing. The method, employing the aforementioned intelligent coating device for polymer release film processing, includes the following steps:

[0038] S1: The polymer release film is wound along a preset path by the conveying mechanism and the winding mechanism, so that the coating is applied to the surface of the polymer release film by the coating mechanism during the winding process.

[0039] S2: During the coating process of the coating mechanism, the coating roller is vibrated by the vibration component, so that the coating and the polymer release film interact to assist the coating of the polymer release film. After the coating is completed, scraping is performed to limit the appearance of wavy patterns in the coating.

[0040] This invention provides an intelligent coating device and method for processing polymer release films. Compared with the prior art, it has the following advantages:

[0041] 1. This invention enables the coating roller to vibrate while applying coating to the surface of a polymer release film, and then uses a comma-shaped doctor blade to scrape the coating. Compared with the traditional method of improving coating effect by vibrating the comma-shaped doctor blade, this invention avoids the wavy texture or unevenness of the coating caused by the doctor blade vibration, thus improving the actual coating effect. Furthermore, the vibration of the coating roller while applying coating to the surface of the polymer release film provides upward support to the polymer release film under the action of the guiding mechanism. The vibration can better enhance the interaction between the surface of the polymer release film and the coating, thereby improving the coating effect.

[0042] 2. This invention uses the current correspondingly set by the second electromagnets at diagonal positions to drive the rotating rod to move by the repulsive force difference generated by the difference in current. The number of second electromagnets is even, and the current is distributed alternately at high and low levels, thereby driving the rotating rod and the coating roller to vibrate. This avoids reducing the vibration frequency of the coating roller when the rotation speed is slow due to coating requirements, thus improving the vibration effect. Compared with the traditional vibration method of striking, the vibration frequency can be controlled by controlling the current of the second and first electromagnets, which facilitates precise control in practice.

[0043] 3. This invention uses a vibration assembly to transmit the vibration of the rotating rod to the vibrating rod and the frame through an air bag, thereby reducing air bubbles in the coating. Compared with the traditional method of reducing air bubbles by vibrating a scraper, this invention eliminates air bubbles before the coating is applied to the polymer release film, improving the coating effect. It also reduces the concave appearance of the coating surface after the air bubbles are expelled, thus improving the smoothness of the coating.

[0044] 4. This invention uses an airbag to connect the rotating rod and the vibrating rod, so as to adjust the vibration frequency and amplitude transmitted from the rotating rod to the vibrating rod by the pressure change of the gas inside the airbag. When the gas pressure inside the airbag is high, the effect of the airbag connecting the rotating rod and the vibrating rod increases, and the frequency and amplitude of the rotating rod acting on the vibrating rod are correspondingly faster and larger. Conversely, the frequency and amplitude are slower and smaller, thus making it easy to adjust the defoaming intensity according to the characteristics of the coating.

[0045] 5. This invention uses a pushing component to drive the pusher plate to move horizontally back and forth, thereby pushing the coating deposited on both sides of the bottom of the storage tank toward the feed pipe. This avoids the coating accumulating on both sides of the bottom of the storage tank for too long, as the coating near the side wall of the storage tank is heated more and will be damaged over time, thus avoiding affecting the subsequent coating effect.

[0046] 6. In this invention, when the lever rotates inside the airbag, it causes a change in the distribution of high-pressure gas inside the airbag, thereby changing the flow of gas inside the airbag and causing corresponding displacement of the airbag and the vibrating rod. Since the lever rotates with the rotating rod, the change in the flow of gas inside the airbag becomes more regular, thus improving the vibration effect of the vibrating rod.

[0072] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0073] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A smart coating device for processing polymer release films includes a base platform 1, a conveying mechanism 5, a dryer 2, and a winding mechanism 3.

[0074] The top of the storage box 71 is provided with a guide mechanism 4 for guiding the winding of the polymer release film so that the polymer release film can be coated with paint by the coating roller 731. A comma scraper mechanism 6 for scraping the paint is provided on one side of the storage box 71.

[0075] In practice, the polymer release film is wound successively through the conveying mechanism 5, the guiding mechanism 4, the inside of the dryer 2, and the winding mechanism 3. During the winding process, the coating mechanism 7 applies a coating to the surface of the polymer release film to increase the specific functions of the polymer release film according to actual needs.

[0076] After coating is completed, the comma-shaped scraper mechanism 6 scrapes the coating on the surface of the polymer release film to improve the uniformity and smoothness of the coating. The above are all existing technologies and will not be described in detail here.

[0077] Please see Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 It also includes a coating mechanism 7 disposed on top of the base 1 and located between the conveying mechanism 5 and the dryer 2, the coating mechanism 7 comprising:

[0078] A storage bin 71 is fixedly mounted on the top of the base platform 1 and located between the conveying mechanism 5 and the dryer 2. A coating assembly 73 is provided on the top of the storage bin 71. The coating assembly 73 includes:

[0079] A rotating rod 732 is disposed on the top of the storage box 71. A coating roller 731 is fixedly sleeved on the middle of the side wall of the rotating rod 732. A vibration assembly 735 for vibrating the coating roller 731 is disposed on the outer side of the storage box 71. An auxiliary mechanism 72 is disposed on both sides of the side wall of the rotating rod 732 and on both sides of the coating roller 731. The auxiliary mechanism 72 and the vibration assembly 735 are symmetrically arranged about the center point of the storage box 71. The vibration assembly 735 includes:

[0080] A fixed frame 7351 is fixedly installed on the outside of the storage box 71. Mounting plates 7352 are fixedly installed on the top and bottom of the inner side of the fixed frame 7351. A first electromagnet 7353 is fixedly installed on the side of the mounting plates 7352 that are close to each other.

[0081] The second electromagnet 7359 is disposed on the side wall of the rotating rod 732 and arranged in a ring array. There is an even number of second electromagnets 7359, and the current connected to the second electromagnets 7359 at the diagonal positions is set accordingly and arranged alternately.

[0082] In practical implementation, the coating roller 731 vibrates while applying the coating to the surface of the polymer release film, and then the coating is scraped off by a comma-shaped doctor blade. Compared with the traditional method of improving the coating effect by vibrating the comma-shaped doctor blade, this method avoids the wavy texture or unevenness of the coating caused by the vibration of the doctor blade, thus improving the actual coating effect. Furthermore, while the coating roller 731 vibrates while applying the coating to the surface of the polymer release film, the polymer release film has an upward supporting force under the action of the guiding mechanism 4. During the vibration process, the interaction between the surface of the polymer release film and the coating is better improved, thereby improving the coating effect.

[0083] The current connected to the second electromagnet 7359 at diagonal positions is set so that the current of the second electromagnet 7359 at diagonal positions is high and low respectively. When the first electromagnet 7353 and the second electromagnet 7359 are energized, a repulsive force is generated between the first electromagnet 7353 and the second electromagnet 7359. The repulsive force difference generated by the difference in current drives the rotating rod 732 to move. The number of second electromagnets 7359 is even, and the high and low currents are distributed alternately. When the second electromagnets 7359 arranged in a circular array rotate with the rotating rod 732, the rotating rod 732 moves up and down, thereby driving the rotating rod 732 and the coating roller 731 to vibrate. This avoids reducing the vibration frequency of the coating roller 731 when the rotation speed is slow due to coating requirements, thereby improving the vibration effect. Compared with the traditional vibration by striking, the vibration frequency can be controlled by controlling the current of the second electromagnet 7359 and the first electromagnet 7353, which facilitates precise control in practice.

[0084] The vibration assembly 735 also includes:

[0085] The first mounting sleeve 7356 is fixedly sleeved on the side wall of the rotating rod 732. The outer wall of the first mounting sleeve 7356 is fixedly sleeved with an isolation cover 7358. The outer wall of the isolation cover 7358 is fixedly connected to the inner side of the second electromagnet 7359.

[0086] The isolation ring 73591 is fixedly sleeved on the outer wall of the isolation cover 7358 and located on both sides of the second electromagnet 7359;

[0087] An electric slip ring 7357 is fixedly sleeved on the outer wall of the first mounting sleeve 7356. One end of the electric slip ring 7357 is connected to the second electromagnet 7359 through a wire, and the other end of the electric slip ring 7357 is connected to an external circuit.

[0088] In practical implementation, the second electromagnet 7359 and the wire are connected by an electric slip ring 7357 so that the wire can be connected to an external circuit, thereby facilitating the power supply and control of the second electromagnet 7359. The electric slip ring 7357 is a ring-shaped electric slip ring, so as not to affect the rotation of the servo motor 733 driving the rotating rod 732 and the coating roller 731.

[0089] The second electromagnet 7359 is installed inside the isolation cover 7358 and the isolation ring 73591, thereby reducing the influence of the external environment on the second electromagnet 7359 and thus reducing the stability of the use of the first electromagnet 7353 and the second electromagnet 7359.

[0090] The vibration assembly 735 also includes:

[0091] The first bearing 7355, the inner ring of the first bearing 7355 is fixedly connected to the outer wall of the first mounting sleeve 7356, the outer ring of the first bearing 7355 is fixedly fitted with the first bearing seat 7354, the outer wall of the first bearing seat 7354 is slidably connected to the inner side of the fixed frame 7351, and there is space for the rotating rod 732 to move up and down.

[0092] The vibration groove 736 is located on the top of the storage box 71 and is fitted onto the side wall of the rotating rod 732. The inner wall of the vibration groove 736 is reserved to allow space for the rotating rod 732 to vibrate.

[0093] In specific implementation, the first bearing 7355 enables the rotating rod 732 to be rotatably connected to the first bearing seat 7354, and since the first bearing seat 7354 is slidably connected to the fixed frame 7351, the rotating rod 732 can rotate while having space for vibration.

[0094] The vibration assembly 735 synchronously drives the rotating rod 732 and the coating roller 731 to vibrate at both ends of the rotating rod 732, thereby improving the stability of the vibration and ensuring the stability of the rotation of the rotating rod 732 and the coating roller 731.

[0095] The coating assembly 73 further includes:

[0096] The servo motor 733 is fixedly installed on the outer wall of the storage box 71. The output shaft of the servo motor 733 is provided with a flexible coupling 734 so that the servo motor 733 drives the rotating rod 732 to rotate through the flexible coupling 734.

[0097] In practical implementation, a flexible coupling 734 is used to connect the servo motor 733 and the rotating rod 732 for transmission, so that the servo motor 733 can drive the rotating rod 732 and the coating roller 731 to rotate, while reducing the problem of vibration affecting the transmission effect.

[0098] Example 2: Please refer to Figure 5 and Figure 13The technical difference between this embodiment and Embodiment 1 is that the coating mechanism 7 further includes:

[0099] The feed pipe 74 is fixedly located at the bottom center of the storage tank 71 to deliver paint into the storage tank 71.

[0100] Please see Figure 13 , Figure 14 , Figure 16 and Figure 17 The auxiliary mechanism 72 includes a resonant assembly 721 and a driving assembly 722. The resonant assembly 721 includes:

[0101] The second mounting sleeve 7215 is fixedly sleeved on the side wall of the rotating rod 732. The outer walls of the second mounting sleeve 7215 are provided with second bearings 7217 at both ends. The inner ring of the second bearing 7217 is fixedly connected to the outer wall of the second mounting sleeve 7215. The outer ring of the second bearing 7217 is fixedly sleeved with a second bearing seat 7218. The outer wall of the second bearing seat 7218 is fixedly sleeved with an air bladder 7211. The top of the air bladder 7211 is reserved with a connection port for connecting the pipeline. The maximum outer wall diameter of the air bladder 7211 is smaller than the outer wall diameter of the coating roller 731.

[0102] The inner wall of the sealing cover 7216 is slidably connected to the outer wall of the second mounting sleeve 7215, and the sliding part is designed with dynamic sealing. The outer wall of the sealing cover 7216 is fixedly connected to the outer side of the second bearing seat 7218.

[0103] The resonant assembly 721 also includes:

[0104] The vibrating rod 7212 is fixedly installed on the bottom of the outer wall of the air bag 7211 and is slidably connected to the inner wall of the storage box 71. While limiting the position of the vibrating rod 7212, it also allows the vibrating rod 7212 to have space for vibration. The bottom of the vibrating rod 7212 is fixedly provided with a frame 7213.

[0105] The first through groove 7214 is formed on the side wall of the vibrating rod 7212.

[0106] In practical implementation, when the rotating rod 732 vibrates, the vibration of the rotating rod 732 is transmitted to the air bag 7211 through the second mounting sleeve 7215, etc., and then transmitted to the vibrating rod 7212 and the frame 7213 through the air bag 7211. This causes the vibrating rod 7212 and the frame 7213 to vibrate within the paint in the storage box 71, thereby reducing air bubbles in the paint. Compared with the traditional method of reducing air bubbles by vibrating a scraper, this method eliminates air bubbles before the paint is applied to the polymer release film, improving the coating effect. Furthermore, it reduces the concave appearance of the paint surface after the air bubbles are expelled, thus improving the smoothness of the coating.

[0107] By using an airbag 7211 to connect the rotating rod 732 and the vibrating rod 7212, the vibration frequency and amplitude transmitted from the rotating rod 732 to the vibrating rod 7212 can be adjusted by the pressure change of the gas inside the airbag 7211. When the gas pressure inside the airbag 7211 is high, the effect of the airbag 7211 connecting the rotating rod 732 and the vibrating rod 7212 increases, and the frequency and amplitude of the rotating rod 732 acting on the vibrating rod 7212 correspondingly increase. Conversely, the frequency and amplitude of the vibration are slowed down and decreased, thus making it easier to adjust the defoaming intensity according to the characteristics of the coating.

[0108] By setting the second bearing 7217 and the second bearing seat 7218, the rotating rod 732 rotates while the air bag 7211 does not rotate, and the vibration can be transmitted to the vibrating rod 7212 and the frame 7213, which is convenient for actual defoaming. In conjunction with the pushing component 722, it is convenient to push the paint deposited on both sides of the bottom of the storage box 71, and avoid some paint from staying in the storage box 71 for too long.

[0109] The sealing cover 7216 seals the space between the second bearing 7217, the second bearing housing 7218, and the second mounting sleeve 7215 to prevent gas leakage from the airbag 7211. The outer wall of the second mounting sleeve 7215 has an annular groove, and an annular slider is placed inside the annular groove. The annular slider is fixedly connected to the inner wall of the sealing cover 7216, so that the sealing cover 7216 slides outside the second mounting sleeve 7215. To make it seal, a sealing ring can be installed between the annular slider and the annular groove to achieve a dynamic seal design. This is existing technology and is not shown in the figure, so it will not be described in detail here.

[0110] Please see Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 18 The actuating component 722 includes:

[0111] The first rod 7221 is sleeved inside the vibrating rod 7212. A limiting groove 72292 is opened at the upper end of the vibrating rod 7212. A limiting ring 72291 is fixedly sleeved on the side wall of the first rod 7221 located in the limiting groove 72292. A first spring is sleeved on the side wall of the first rod 7221 located in the limiting groove 72292. The first spring is located at the bottom of the limiting ring 72291 so that the first rod 7221 has an upward tendency. The upper end of the side wall of the first rod 7221 and the upper end of the vibrating rod 7212 are dynamically sealed. A cavity for sleeved first rod 7221 is opened inside the vibrating rod 7212.

[0112] The lever 7222 is fixedly installed on the outer wall of the second mounting sleeve 7215 and located inside the airbag 7211. The side of the lever 7222 away from the second mounting sleeve 7215 and the top of the first rod 7221 are both arc-shaped.

[0113] The second rod 7223 is fixedly installed at the bottom of the first rod 7221 and extends along the first through groove 7214 to the outside of the vibrating rod 7212. The bottom of the second rod 7223 is fixedly provided with a stop plate 7224, and the side of the stop plate 7224 away from the first rod 7221 is designed to be inclined.

[0114] The actuating component 722 also includes:

[0115] The third rod 7227 is sleeved on the side wall of the storage box 71 and has a dynamic sealing design with the side wall of the storage box 71. The side wall of the third rod 7227 is sleeved in the frame 7213. The side wall of the third rod 7227 located in the storage box 71 has a second through groove 7228. The side wall of the abutment 7224 is sleeved in the second through groove 7228.

[0116] Push plate 7225 is fixedly installed at one end of the third rod 7227 located inside the storage box 71. The bottom of push plate 7225 is in contact with the bottom of the inner wall of storage box 71. The side wall of push plate 7225 is provided with guide holes 7226 arranged at intervals.

[0117] The fastener 7220 is fixed to the outer wall of the storage box 71 and sleeved on the side wall of the third rod 7227. A baffle 7229 is fixedly provided at one end of the third rod 7227 outside the storage box 71. A second spring is sleeved on the side wall of the third rod 7227 and the second spring is located between the fastener 7220 and the baffle 7229.

[0118] In practical implementation, when the rotating rod 732 rotates, it drives the paddle block 7222 to rotate along the center line of the rotating rod 732. During the rotation, the first rod 7221 is squeezed to move downward against the elastic force of the first spring. The first rod 7221 drives the second rod 7223 and the abutment plate 7224 to move downward. Under the action of the inclined surface of the abutment plate 7224, the third rod 7227 and the push plate 7225 are driven to move horizontally against the elastic force of the second spring. This pushes the paint deposited on both sides of the bottom of the storage box 71 toward the feed pipe 74, so as to facilitate the paint... The paint discharged through the feed pipe 74 moves upward, thus preventing the paint from accumulating on both sides of the bottom of the storage tank 71 for too long. In order to ensure the fluidity and adhesion of the paint, a heating mechanism is usually installed outside the storage tank 71 to ensure that the paint is in a suitable temperature range. If the paint accumulates in the same position in the storage tank 71 for a long time, the paint near the side wall of the storage tank 71 will be heated more, which will damage the paint over time and affect the subsequent coating effect. The movement of the push plate 7225 driven by the rotation of the coating roller 731 facilitates actual use.

[0119] By setting guide holes 7226, the paint on both sides of the push plate 7225 can flow to each other, avoiding paint accumulation on the side of the push plate 7225 away from the feed pipe 74, thus improving the performance.

[0120] The second rod 7223 can extend outside the vibrating rod 7212 through the first through groove 7214, thereby cooperating with the second through groove 7228. This prevents the position of the third rod 7227 with the second through groove 7228 from moving outside the storage box 71, thus avoiding the problem of the third rod 7227 and the storage box 71 not being able to seal, and does not affect the use of the vibrating rod 7212.

[0121] When the toggle block 7222 rotates inside the airbag 7211, it changes the distribution of the high-pressure gas inside the airbag 7211, thereby changing the flow of gas inside the airbag 7211 and causing the airbag 7211 and the vibrating rod 7212 to be displaced accordingly. Since the toggle block 7222 rotates with the rotating rod 732, the flow of gas inside the airbag 7211 changes more regularly, thereby improving the vibration effect of the vibrating rod 7212.

[0122] The servo motor 733 and the first electromagnet 7353 of this invention are connected to the controller and power supply through wires, which facilitates actual control and use. This is prior art and will not be described in detail here.

[0123] This invention also provides a method for using an intelligent coating device for polymer release film processing. The method includes the following steps:

[0124] S1: The polymer release film is wound along a preset path by the conveying mechanism 5, the guiding mechanism 4 and the winding mechanism 3. During the winding process, the coating mechanism 7 applies the coating to the surface of the polymer release film. After the coating is completed, the polymer release film coated with the coating is dried by the dryer 2. After drying, it is wound up by the winding mechanism 3.

[0125] S2: During the coating process of the coating mechanism 7, the coating roller 731 is vibrated by the vibration component 735, so that the coating material and the polymer release film interact to assist the coating of the polymer release film. After the coating is completed, the coating is scraped to limit the appearance of wavy patterns in the coating material.
