Description

Technical Field

[0001] This utility model relates to the field of automated coating equipment, specifically to an automated equipment for coating, film application and curing. Background Technology

[0002] In the field of automated coating equipment, especially in the field of automated coating and texture processing for floor surfaces, coatings and textures on board surfaces are mostly formed by directly applying adhesive, that is, using coating rollers to directly transfer the paint onto the board surface. However, this type of equipment also has some shortcomings: First, differences in the flatness of the board surface can easily lead to uneven coating thickness, especially with poor adaptability to uneven boards; second, during the direct coating process, the paint is in direct contact with the board, and is greatly affected by factors such as the board itself, resulting in unstable paint curing effects, and is prone to local premature curing or insufficient curing, leading to inconsistent coating properties such as wear resistance and adhesion, which restricts production continuity and product consistency. Utility Model Content

[0003] The problem to be solved by this utility model is to provide an automated device for applying adhesive, coating and curing.

[0004] To solve the above problems, this utility model provides an automated device for adhesive coating and curing. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows:

[0006] As a further improvement of this utility model, the coating roller and the metering roller are equipped with a synchronous advance and retreat mechanism, which enables the coating roller and the metering roller to move closer to or further away from the carrier roller synchronously; the metering roller has an independent advance and retreat mechanism, which enables the metering roller to move closer to or further away from the coating roller synchronously.

[0007] As a further improvement of this utility model, the synchronous advance and retreat mechanism fixes the frame through a linear guide slider mechanism. The synchronous advance and retreat mechanism is connected to the frame through a linear drive cylinder, which drives the coating roller and the metering roller to move synchronously. The independent advance and retreat mechanism includes a sliding bearing seat and a lead screw located inside the synchronous advance and retreat mechanism. The sliding bearing seat is assembled with the shaft end of the metering roller, and one end of the lead screw is assembled with the sliding bearing seat. The lead screw drives the sliding bearing seat and the metering roller to move closer to or further away from the coating roller.

[0008] As a further improvement of this utility model, the bearing roller is divided into a first cylindrical section and a second cylindrical section according to different diameters. The diameter of the first cylindrical section is smaller than that of the second cylindrical section. The first cylindrical section is located at both ends of the axial direction of the second cylindrical section. A shoulder is formed at the junction of the first cylindrical section and the second cylindrical section. The second cylindrical section is used to adhere the coating.

[0009] As a further improvement of this utility model, the release film between the unwinding roller and the coating transfer assembly passes through several transition guide rollers, and the release film between the unwinding roller and the peeling transfer assembly also passes through several transition guide rollers. The transition guide rollers guide the release film. The central angle corresponding to the contact point between the release film and the carrier roller is the anomalous angle. The conveyor belt is located below the coating transfer assembly.

[0010] As a further improvement of this utility model, the peeling and transfer assembly includes a pressure roller, which is used to convey and extrude the release film. The pressure roller includes a first pressure roller and a second pressure roller, and each of the first pressure roller and the second pressure roller has an independent vertical lifting mechanism. The conveyor belt has a bottom roller inside, which includes a first bottom roller and a second bottom roller. The first bottom roller and the second bottom roller are located directly below the first pressure roller and the second pressure roller, respectively.

[0011] As a further improvement of this utility model, the vertical projections of the unwinding roller and the take-up roller do not intersect; the shaft ends of the unwinding roller and the take-up roller are equipped with J-shaped brackets, the J-shaped brackets have an opening facing one side horizontally, and a hand-tightening bolt is provided at the opening of the J-shaped brackets.

[0012] As a further improvement of this utility model, the release film between the carrier roller and the peeling transfer assembly is conveyed obliquely downward, and the release film in the peeling transfer assembly is conveyed horizontally; the curing assembly includes a first UV curing group and a second UV curing group, with the first UV curing group provided on one side of the release film between the carrier roller and the peeling transfer assembly, and the second UV curing group provided on one side of the release film in the peeling transfer assembly.

[0013] As a further improvement of this utility model, a reflux collection mechanism is provided below the coating and transfer assembly.

A reflux heating box is provided below the outlet of the reflux trough, and a filter screen is provided inside the reflux heating box.

[0014] As a further improvement of this utility model, the coating transfer assembly, curing assembly, and peeling transfer assembly are all covered by an equipment protective cover. The equipment protective cover has a first window for feeding and a second window for discharging. The first window and the second window are located on both sides of the equipment protective cover, and the take-up roller and the unwind roller are located outside the first window.

[0015] The beneficial technical effects of using the automated equipment for adhesive coating and curing described in this application are:

[0016] First, by using a release film to catch the coating on the coating roller, the problem of uneven coating thickness caused by differences in the flatness of the board surface when the coating is directly applied to the board is avoided. In particular, it improves the adaptability to uneven boards and ensures the uniformity of the coating.

[0017] Secondly, the coating can be photocured on the release film before being transferred to the substrate, which reduces the interference of substrate factors on the curing process and avoids local premature curing or insufficient curing, which is conducive to improving the consistency of coating properties such as wear resistance and adhesion.

[0018] Finally, the design of the conveyor belt and the release film being at an angle to each other allows the cured coating to be stably transferred from the release film to the surface of the board through their cooperation, improving the reliability and efficiency of coating transfer and ensuring production continuity.

Detailed Implementation

[0034] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0035] In order to achieve the purpose of this utility model, such as Figure 1 As shown, an automated coating and curing device includes: an unwinding and rewinding assembly, including an unwinding roller 2 capable of unwinding one end of a release film 3, and a rewinding roller 1 capable of rewinding the other end of the release film 3; a coating and transfer assembly 4, including a carrier roller 14, a coating roller 15, and a metering roller 16 arranged adjacent and parallel to each other, with the coating roller 15 located between the carrier roller 14 and the metering roller 16, forming a coating accumulation space above the junction of the coating roller 15 and the metering roller 16; the coating roller 15 can adhere to and carry the coating, and the release film 3 can receive the coating adhered to the coating roller 15 when it passes over the carrier roller 14; and a curing assembly for photocuring the release film 3 with the coating adhered to it. Figure 6As shown, the peeling and transfer assembly includes a conveyor belt 45 capable of conveying the sheet material. The conveying direction of the conveyor belt 45 is at an angle to the conveying direction of the release film 3 as it leaves the peeling and transfer assembly. The conveyor belt 45, in conjunction with the release film 3, transfers the cured coating from the release film 3 to the surface of the sheet material.

[0036] To clearly illustrate the structural principles Figure 6 Red lines represent the release film 3, and green lines represent the conveyor belt 45. Additionally, fluids such as adhesives belong to the aforementioned coatings. This equipment can be used in flooring processing and for digital printing on tile surfaces, simulating the visual effects and physical properties of existing tiles. This equipment is also a surface coating transfer device.

[0037] The beneficial effects of adopting the above technical solution are as follows: Using the release film 3 as an intermediate carrier to receive the coating transferred by the coating roller 15, the coating is transferred to the surface of the substrate after curing, avoiding the problem of uneven coating thickness caused by uneven substrate surfaces in traditional direct coating processes. The curing process acts on the release film 3 rather than the substrate, allowing the coating to stably complete photocuring in an independent environment, eliminating interference from substrate material or temperature on the curing effect, solving the problem of possible premature or insufficient curing in certain areas, and improving the coating's wear resistance and adhesion. Furthermore, the conveyor belt 45 in the transfer assembly forms a specific angle with the conveying direction of the release film 3, combined with the squeezing action of the pressure rollers, to achieve efficient peeling and precise transfer of the cured coating to the substrate surface, improving production continuity and product consistency.

[0038] like Figure 3 As shown, in some other embodiments of this utility model, the coating roller 15 and the metering roller 16 are provided with a synchronous advance and retreat mechanism 40, which enables the coating roller 15 and the metering roller 16 to synchronously approach or move away from the carrier roller 14. In addition, the metering roller 16 has an independent advance and retreat mechanism, which enables the metering roller 16 to synchronously approach or move away from the coating roller 15.

[0039] The beneficial effects of adopting the above technical solution are as follows: the synchronous advance and retreat mechanism 40 enables the coating roller 15 and the metering roller 16 to adjust their gap with the carrier roller 14 synchronously, while the independent advance and retreat mechanism controls the gap between the metering roller 16 and the coating roller 15 separately. The dual adjustment mechanism can accurately adapt to the requirements of different viscosity coatings and coating thicknesses, avoid over-coating or under-coating caused by roller linkage in traditional equipment, improve coating uniformity, and reduce raw material waste.

[0040] In some other embodiments of this utility model, the synchronous advance and retreat mechanism 40 is fixed to the frame via a linear guide slider mechanism 41. The synchronous advance and retreat mechanism 40 is connected to the frame via a linear drive cylinder 42, which drives the coating roller 15 and the metering roller 16 to move synchronously. The independent advance and retreat mechanism includes a sliding bearing seat 4003 and a lead screw 4001 located inside the synchronous advance and retreat mechanism 40. The sliding bearing seat 4003 is assembled with the shaft end of the metering roller 16, and one end of the lead screw 4001 is assembled with the sliding bearing seat 4003. The lead screw 4001 drives the sliding bearing seat 4003 and the metering roller 16 to move closer to or further away from the coating roller 15. The linear drive cylinder 42 is preferably a linear pneumatic cylinder, and the end of the output rod of the linear drive cylinder 42 is fixed to the frame via a corner bracket 43.

[0041] The beneficial effects of adopting the above technical solution are as follows: the linear guide slider mechanism 41 and the linear drive cylinder 42 drive synchronously forward and backward, and the lead screw 4001 controls the sliding bearing seat 4003 to adjust the position of the quantitative roller 16. The mechanical closed-loop design ensures the parallelism and repeatability of the roller movement, and the lead screw drive can eliminate backlash drift, making it suitable for high-speed continuous production environments, reducing debugging time and improving the long-term stability of the equipment.

[0042] In another embodiment, the synchronous advance and retreat mechanism 40 includes a rectangular frame 20, one end of which is a stationary bearing seat 4002, such as... Figure 3 As shown, the shaft end of the coating roller 15 is assembled with the stationary bearing housing 4002. Additionally, as... Figure 9 As shown, the linear guide slider mechanism 41 includes a slider 4101 and a guide rail 4102, and several sliders are movably mounted on a guide rail 4102.

[0043] Release film 3 is also a carrier film. The operation mode of release film 3 is to ensure that it maintains a certain tension and runs smoothly.

[0044] In another embodiment, the take-up roller 1 is driven by a servo motor to take up the winding and ensure winding tension. For example... Figure 4 As shown, the unwinding roller 2 uses a combination of magnetic powder brake 39 to unwind, ensuring the unwinding tension of the release film 3.

[0045] The coating roller 15 and the metering roller 16 are each driven by a separate motor. The amount of adhesive applied can be controlled by adjusting the gap between the metering roller 16 and the coating roller 15. The gap between the coating roller 15 and the carrier roller 14 can also be adjusted to ensure uniform coating.

[0046] like Figure 1 , Figure 3As shown, in some other embodiments of this utility model, the bearing roller 14 is divided into a first cylindrical section 1402 and a second cylindrical section 1403 according to different diameters. The diameter of the first cylindrical section 1402 is smaller than the diameter of the second cylindrical section 1403. The first cylindrical section 1402 is located at both ends of the axial direction of the second cylindrical section 1403. A shoulder portion 1401 is formed at the junction of the first cylindrical section 1402 and the second cylindrical section 1403. The second cylindrical section 1403 is used to adhere coatings.

[0047] The beneficial effects of adopting the above technical solution are as follows: The stepped shaft design of the bearing roller 14 forms a shoulder 1401 with the first cylindrical section 1402 and the second cylindrical section 1403, thereby physically restricting the lateral displacement of the release film 3. Therefore, the wide roller surface of the second cylindrical section 1403 ensures that the coating fully covers the effective area of ​​the release film 3, and the shoulder 1401 prevents the coating from overflowing, reducing the phenomenon of adhesive accumulation at the edges. That is, the coating and adhesive will not stick to the first cylindrical section 1402, improving the neatness of the coating edge and reducing the frequency of cleaning and maintenance.

[0048] In another embodiment, the carrier roller 14 is designed as a stepped shaft, and the step width is determined according to the width of the release film 3, which in turn determines the shaft length of the second cylindrical segment 1403. The center height of the coating roller 15 and the metering roller 16 are consistent, thereby facilitating uniform coating amount.

[0049] In another embodiment, the axis of the coating roller 15 is longer than that of the carrier roller 14, so that the coating surface of the release film 3 can be uniformly coated with the coating material.

[0050] In another embodiment, the metering roller 16 uses a high-precision reducer to control the coating amount, and the coating thickness is 10µm to 30µm.

[0051] like Figure 6 As shown, in some other embodiments of this invention, the release film 3 between the unwinding roller 2 and the coating / transfer assembly 4 passes through several transition guide rollers 13, and the release film 3 between the unwinding roller 2 and the peeling / transfer assembly also passes through several transition guide rollers 13. The transition guide rollers 13 guide and deflect the release film 3. The central angle corresponding to the contact point between the release film 3 and the carrier roller 14 is the anomalous angle. The conveyor belt 45 is located below the coating / transfer assembly 4.

[0052] The beneficial effects of adopting the above technical solution are as follows: the transition guide roller 13 guides the release film 3 to form an angled coating of the carrier roller 14, increasing the contact area to improve the coating transfer efficiency. The guide roller layout optimizes the tension distribution of the film material, avoiding wrinkles or bubbles during operation. In addition, the conveyor belt 45 is located below the coating transfer assembly 4, shortening the transfer path of the cured coating and reducing the risk of coating damage during the transfer process.

[0053] In another embodiment, the transition guide wheel 13 is made of aluminum alloy, has a diameter of 120mm, and has a hard anodized mirror finish.

[0054] In some other embodiments of this invention, the peeling and transfer assembly includes pressure rollers for conveying and extruding the release film 3. The pressure rollers include a first pressure roller 6 and a second pressure roller 8, each having an independent vertical lifting mechanism. The conveyor belt 45 has a bottom roller inside, including a first bottom roller 10 and a second bottom roller 11, which are located directly below the first pressure roller 6 and the second pressure roller 8, respectively.

[0055] The beneficial effects of adopting the above technical solution are as follows: the first pressure roller 6 and the second pressure roller 8 cooperate with independent lifting mechanisms 17 and 18, and the first bottom roller 10 and the second bottom roller 11 are aligned vertically below. The multi-stage pressing design uses the elasticity of the rubber rollers to adapt to the unevenness of the board surface, ensuring uniform pressure distribution. The alignment structure avoids undulation when the release film 3 is removed, improving the integrity of the coating transfer, and is especially suitable for processing curved or textured boards.

[0056] like Figure 6 As shown, in another embodiment, the conveyor belt 45 is a closed-loop conveyor belt that encloses the conveyor tension roller 9, the first bottom roller 10, the second bottom roller 11, and the conveyor drive roller 12. Along the conveying direction, the conveyor tension roller 9, the first bottom roller 10, the second bottom roller 11, and the conveyor drive roller 12 are arranged sequentially, with their top surfaces at the same horizontal height. The conveyor tension roller 9 is used to adjust the tension of the conveyor belt 45, ensuring the conveyor belt 45 operates at high precision. The conveyor drive roller 12 has the same linear speed as the second pressure roller 8 and the take-up roller 1.

[0057] In another embodiment, the first pressure roller 6 is a rubber wheel with a diameter of 100mm to 600mm. The rubber wheel has a Shore hardness of 35 to 80. During the molding process, when the coating on the release film 3 bonds with the sheet material, the rubber elasticity of the rubber wheel is used to solve the defect of unevenness on the surface of the sheet material. In addition, the second pressure roller 8 uses a servo motor and a reducer to control the rotation speed of the second pressure roller 8, ensuring that the rotation speed of the second pressure roller 8 is consistent with that of the take-up roller 1 and the conveying drive group 12.

[0058] In another embodiment, the first bottom roller 10 is a 200mm diameter rubber roller. The position of the first bottom roller 10 is on the same vertical line as the first pressure roller 6, ensuring consistent pressure on the product from top to bottom and guaranteeing coating accuracy. The second bottom roller 11 has the same diameter as the first bottom roller 10, also a 200mm diameter rubber roller, and is positioned perpendicular to the first pressure roller 6, ensuring consistent pressure on the product from top to bottom and preventing unevenness when the release film 3 detaches from the substrate, thus ensuring coating accuracy.

[0059] In another embodiment, the first pressure roller 6 and the second pressure roller 8 each have an independent vertical lifting mechanism, namely the first pressure roller lifting group 17 and the second pressure roller lifting group 18. The first pressure roller lifting group 17 and the second pressure roller lifting group 18 use a motor, a reducer, and an encoder controller to ensure the lifting accuracy of the first pressure roller 6 and the second pressure roller 8 pressing together.

[0060] like Figure 2 As shown, in some other embodiments of this utility model, the vertical projections of the unwinding roller 2 and the take-up roller 1 do not intersect. J-shaped brackets 36 are fitted to the shaft ends of the unwinding roller 2 and the take-up roller 1. The J-shaped brackets 36 have an opening facing horizontally to one side, and a hand-tightening bolt 38 is provided at the opening of the J-shaped brackets 36. The hand-tightening bolt 38 can control the width of the opening of the J-shaped brackets 36, that is, control the width value of the opening of the J-shaped brackets 36.

[0061] The beneficial effects of adopting the above technical solution are: the layout where the vertical projections of the unwinding roller 2 and the take-up roller 1 do not intersect reduces the longitudinal space occupied by the equipment, instead of being arranged vertically, so it does not affect the independent replacement of the unwinding roller 2 or the take-up roller 1 by the overhead crane. In addition, the J-shaped bracket 36, together with the hand-tightening bolt 38, fixes the air expansion shaft 37. When replacing, the shaft ends of the unwinding roller 2 and the take-up roller 1 enter and exit through the opening of the J-shaped bracket 36. When locking is required, the hand-tightening bolt 38 is further tightened to seal the opening of the J-shaped bracket 36, preventing the unwinding roller 2 and the take-up roller 1 from loosening at will.

[0062] like Figure 2 As shown, in another embodiment, the unwinding roller 2 and the winding roller 1 both have an air-expanding shaft 37 at their axial ends. The release film 3 is wound onto the air-expanding shaft 37, and the shaft end of the air-expanding shaft 37 is movably assembled with the J-shaped bracket 36 through a ball bearing. The J-shaped bracket 36 makes semi-enclosed contact with the outer wall of the ball bearing.

[0063] like Figure 1 , Figure 6 As shown, in some other embodiments of this utility model, the release film 3 between the carrier roller 14 and the peeling transfer assembly is conveyed obliquely downwards, while the release film 3 within the peeling transfer assembly is conveyed horizontally. The curing assembly includes a first UV curing group 5 and a second UV curing group 7. The first UV curing group 5 is disposed on one side of the release film 3 between the carrier roller 14 and the peeling transfer assembly, and the second UV curing group 7 is disposed on one side of the release film 3 within the peeling transfer assembly.

[0064] The beneficial effects of adopting the above technical solution are as follows: the release film 3 is conveyed obliquely downwards, first passing through the first UV curing group 5 to achieve semi-curing, and then continuing to be conveyed horizontally, passing through the second UV curing group 7 to complete the oxygen-free final curing. This segmented curing design avoids premature deformation of the coating accumulation space due to heat, thus improving curing efficiency. The angle isolation design of the curing groups reduces UV scattering to the coating area, ensuring the liquid stability of the coating.

[0065] In another embodiment, the first UV curing group 5 uses a 395nm LED light source to achieve a semi-cured state. The second UV curing group 7 uses a 395nm LED light source to achieve an oxygen-free curing state. This improves curing efficiency.

[0066] In another embodiment, the light emission directions of the first UV curing group 5 and the second UV curing group 7 are both perpendicular to the plane of the adjacent release film 3. The first UV curing group 5 is arranged at an angle to prevent the light emitted by the first UV curing group 5 from shining on the coating between the carrier roller 14 and the coating roller 15, thus preventing the coating in the coating accumulation space from curing and deforming prematurely.

[0067] like Figure 10 As shown, in some other embodiments of this utility model, a reflux collection mechanism 21 is provided below the coating and transfer assembly 4. The reflux collection mechanism 21 includes a side groove funnel 35. The bottom of the side groove funnel 35 is connected to a downwardly extending reflux pipe 34. The bottom of the two reflux pipes 34 is provided with a diagonally arranged reflux groove 31. A reflux heating box 22 is provided below the outlet of the reflux groove 31. A filter screen 32 is provided inside the reflux heating box 22.

[0068] The beneficial effects of adopting the above technical solution are: the overflow glue is collected by the side groove funnel 35, and then flows through the return pipe 34 to the inclined return groove 31. After the filter screen 32 separates the impurities, it enters the return heating box 22 for recycling.

[0069] In another embodiment, the reflux collection mechanism 21 also includes a pump 23. The overflow paint in the coating and transfer assembly 4 flows through the reflux collection mechanism 21 to the reflux heating box 22, and then the pump 23 sends the paint in the reflux heating box 22 back into the coating and transfer assembly 4, thereby realizing the recycling of paint.

[0070] In another embodiment, the reflux heating tank 22 employs a double-layered stainless steel shell, with hot water inside the double shell. The hot water is kept separate from the coating to prevent contact, thus achieving water bath heating. The temperature of the heating water is monitored in real time. Two layers of filter screens 32 are vertically arranged inside the reflux heating tank 22 to ensure that the filtered coating is clean and free of air bubbles. Figure 10 As shown, the filter screen 32 divides the reflux heating box 22 into two chambers: the turbid liquid zone 2201 and the clean liquid zone 2202. The turbid liquid zone 2201 is located below the outlet of the reflux tank 31.

[0071] In another embodiment, a receiving tray 19 is provided below the coating and transfer assembly 4, and the receiving tray 19 is located between two side groove funnels 35. When the coating and transfer assembly 4 is being adjusted, this is a protective measure to prevent the coating from falling onto the release film 3 below. The receiving tray 19 is made of stainless steel and has a handle for easy removal, which facilitates cleaning of the receiving tray 19.

[0072] like Figure 11 , Figure 12 As shown, in some other embodiments of this utility model, the coating and transfer assembly 4, the curing assembly, and the peeling and transfer assembly are all covered by an equipment protective cover 33. The equipment protective cover 33 has a first window 3301 for feeding and a second window 3302 for discharging, with the first window 3301 and the second window 3302 located on opposite sides of the equipment protective cover 33. The take-up roller 1 and the unwind roller 2 are located outside the first window 3301.

[0073] To facilitate the demonstration of the internal structure, Figures 1 to 10 33 is hidden, and Figure 11 and Figure 12 The equipment protective cover 33 is shown. The equipment protective cover 33 partially encloses the internal equipment mechanism, improves operational safety, and reduces the entry of external impurities.

[0074] The bottom of the entire equipment is the base frame assembly 30, and the bottom of the equipment protective cover 33 is fixed to the base frame assembly 30. The frame includes two vertically parallel frame side plates 44, and the shaft ends of the unwinding and rewinding assembly, the coating and transfer assembly 4, and the peeling and transfer assembly are all assembled and fixed to the frame side plates 44.

[0075] The beneficial effects of adopting the above technical solution are as follows: the equipment protective cover 33 encloses the core components, and the first window 3301 and the second window 3302 are respectively located on the feeding side and the discharging side. The protective design blocks environmental dust from contaminating the coating, improving the working environment. The external placement of the unwinding and rewinding components facilitates their hoisting and replacement.

[0076] like Figure 6 As shown, the release film 3 starts from the unwinding roller 2, first tangent to the bottom of the first guide roller 1301, then tangent to the top of the second guide roller 1302, then tangent to the top of the third guide roller 1303, then tangent to the top of the carrier roller 14, then tangent to the bottom of the first pressure roller 6, then tangent to the bottom of the second pressure roller 8, then tangent to the top of the fourth guide roller 1304, then tangent to the bottom of the fifth guide roller 1305, and finally reaches the take-up roller 1. The first guide roller 1301, the second guide roller 1302, and the third guide roller 1303 are all located below the carrier roller 14, the coating roller 15, and the metering roller 16. Additionally, the first pressure roller 6, the second pressure roller 8, the fourth guide roller 1304, and the fifth guide roller 1305 are all located below the carrier roller 14, the coating roller 15, and the metering roller 16.

[0077] like Figure 4As shown, the first motor 50 drives the take-up roller 1 to rotate, the second motor 51 drives the metering roller 16 to rotate, the third motor 52 drives the coating roller 15 to rotate, the fourth motor 53 drives the second pressure roller 8 to rotate, the fifth motor 54 drives the second pressure roller 8 to move vertically up and down via a lead screw mechanism, the sixth motor 55 drives the first pressure roller 6 to move vertically up and down via a lead screw mechanism, and the seventh motor 56 drives the conveying drive roller 12 to rotate. The motors also have reduction gears.

[0078] like Figure 5 , Figure 7 As shown, the automated equipment for coating and curing also includes a micro switch 46 and a color sensor 47. Figure 5 , Figure 7 Because the protective cover 33 conceals the equipment, the fixing mechanisms for the micro switch 46 and the color sensor 47 are also hidden. The micro switch 46 is parallel to the axes of the carrier roller 14, coating roller 15, and metering roller 16. It is located on the same axis as the carrier roller 14, coating roller 15, and metering roller 16, between the unwinding roller 2 and the metering roller 16. It is used to sense whether the unwinding roller 2 and the take-up roller 1 are in the correct positions. The micro switch 46 is electrically connected to the coating / transfer assembly 4. Only when the unwinding roller 2 and the take-up roller 1 are in the correct positions will the micro switch 46 drive the coating / transfer assembly 4 to operate. Additionally, the color sensor 47 is located above the feed inlet of the conveyor belt 45 and faces downwards to sense the color of the incoming material.
