Description

Technical Field

[0001] This utility model relates to the field of coating equipment, and in particular to a double-sided coating device and a coating equipment using the double-sided coating device. Background Technology

[0002] Products such as acrylic, glass, metal sheets, and plastic products often require coating during the production process to protect their surfaces from scratches, contamination, or UV damage, while also enhancing durability or aesthetics. For example, acrylic sheets are widely used in billboards, decorative panels, and electronic product casings; their surfaces are easily scratched, therefore protective or functional films need to be applied during production, transportation, or processing to ensure product quality and lifespan.

[0003] Currently, most lamination processes in related technologies rely on manual operation or semi-automatic equipment. Manual lamination typically involves cutting the film material by hand or using simple mechanical assistance, then applying it piece by piece to the product surface. Rollers or pressure plates are usually used to flatten the protective film onto the acrylic plate. Semi-automatic equipment, on the other hand, uses preset pressure and speed to align the film material with the product before lamination.

[0004] However, the relevant technology has the following drawbacks: when it is necessary to coat the front and back of the product, it is necessary to manually coat one side of the product before coating the other side, which is inefficient. Utility Model Content

[0005] The main purpose of this invention is to provide a double-sided laminating device and a laminating equipment using the double-sided laminating device, in order to solve the problem of low efficiency in existing double-sided laminating work.

[0006] To achieve the above objectives, this utility model proposes a double-sided coating device, comprising:

[0013] In some embodiments, the double-sided coating apparatus further includes a transmission assembly, and the coating drive is connected to the first coating roller shaft, the second coating roller shaft and the third coating roller shaft via the transmission assembly.

[0014] In some embodiments, the transmission assembly includes a drive sprocket, a plurality of driven sprockets, and a transmission chain. The drive sprocket is connected to the output end of the coating drive. One end of the first coating roller shaft, the second coating roller shaft, and the third coating roller shaft is provided with the driven sprocket. The transmission chain is meshed with the drive sprocket and each of the driven sprockets.

[0015] In some embodiments, the double-sided laminating device further includes a first film-feeding roller, a second film-feeding roller, and a third film-feeding roller, wherein the first film-feeding roller and the second film-feeding roller are located above the first laminating roller, and the third film-feeding roller is located below the second laminating roller; wherein:

[0016] The first film material is wound on the first film feeding roller shaft;

[0017] The second film feeding roller is wound with the second film material, and the second film feeding roller is horizontally spaced from the first film feeding roller.

[0018] The third film material is wound on the third film unwinding roller.

[0019] In some embodiments, the double-sided laminating device further includes two tensioning components, each of which includes:

[0020] A first lifting drive component is disposed on the mounting base;

[0021] The base is located at the output end of the first lifting drive component;

[0022] The tensioning shaft is disposed on the base;

[0023] The first film material is wound around the tensioning shaft of one of the two tensioning components and then onto the first coating roller shaft, and the second film material is wound around the tensioning shaft of the other of the two tensioning components and then onto the second coating roller shaft.

[0024] In some embodiments, the film cutting mechanism includes:

[0025] A first lateral movement drive component is disposed on the mounting base;

[0026] The second lifting drive is located at the output end of the first lateral drive;

[0027] The cutting component is located at the output end of the second lifting drive component;

[0028] The first lateral drive is used to drive the cutting piece to move in the horizontal direction, and the second lifting drive is used to drive the cutting piece to move in the vertical direction.

[0029] In some embodiments, the double-sided coating apparatus further includes a cleaning component located on the inlet side of the first channel, the cleaning component comprising:

[0030] A first cleaning roller is rotatably mounted on the mounting base;

[0031] The second cleaning roller is rotatably disposed on the mounting base and spaced apart below the first cleaning roller. A second channel corresponding to the first channel is formed between the second cleaning roller and the first cleaning roller.

[0032] Furthermore, this utility model proposes a laminating device, including a base, a feeding device, a discharging device, and a double-sided laminating device as described in the foregoing embodiments, all disposed on the base. The feeding device is connected to the inlet end of the double-sided laminating device and is used to convey products to the double-sided laminating device.

[0037] The flipping drive is used to drive the gripper to transfer the product to the receiving conveyor belt, and the receiving conveyor belt transports the product into the first channel.

[0038] This application solution utilizes a first and a second coating roller shaft spaced apart on the mounting base. The two coating rollers are respectively wound with a first film and a second film for coating the two opposite surfaces of the product. When the coating drive unit drives the first and second coating roller shafts to move, the first and second coating rollers rotate, conveying the product forward. Simultaneously, the first and second film materials are applied to the opposite surfaces of the product during this conveying process, thus achieving synchronous coating on both sides of the product. After coating is completed, a film cutting mechanism cuts the film material, completing the fully automated coating process. Compared to manual two-sided coating, this significantly improves work efficiency. Attached Figure Description

[0049] This application provides a double-sided coating device, referring to... Figures 1 to 3 In a preferred embodiment, the double-sided coating device includes:

[0050] Mounting base 1;

[0051] The first coating roller 2 is rotatably mounted on the mounting base 1, and the first coating roller 2 is wound with the first film material;

[0052] The second coating roller 3 is rotatably mounted on the mounting base 1. The second coating roller 3 is spaced apart from the first coating roller 2 and a first channel is formed between them. The first channel is used for the product to pass through. The second coating roller 3 is wound with a second film material.

[0053] The film-coating drive component 4 is located on the mounting base 1 and is connected to the first film-coating roller shaft 2 and the second film-coating roller shaft 3 for driving the first film-coating roller shaft 2 and the second film-coating roller shaft 3 to rotate.

[0054] In this embodiment, the double-sided laminating device proposed in this application is mainly used to simultaneously cover two opposite sides of a product with film to achieve a laminating process for protection, decoration, or other functions. The mounting base 1 serves as the main support structure of the device, used to fix and support other components. The first laminating roller 2 and the second laminating roller 3 are respectively wound with the first film and the second film. The first laminating roller 2 and the second laminating roller 3 are rotatably mounted on the mounting base 1 and are spaced apart, forming a first channel for the product to pass through.

[0055] The film-coating drive unit 4 is connected to the first film-coating roller shaft 2 and the second film-coating roller shaft 3, providing power to drive the two roller shafts to rotate synchronously or in coordination.

[0056] Taking acrylic sheets as an example, and applying a film to the acrylic sheet, the film coating process is briefly described as follows:

[0057] First, the acrylic sheet is manually or by a conveyor to the inlet of the first channel and then fed into the first channel.

[0058] After the lamination drive 4 is activated, it drives the first lamination roller 2 and the second lamination roller 3 to rotate. During rotation, the first lamination roller 2 releases the first film material, and the second lamination roller 3 releases the second film material. As the acrylic sheet passes through the first channel, the first and second film materials are respectively bonded to the opposite sides (e.g., the upper and lower surfaces) of the acrylic sheet that are in contact with the first and second lamination rollers 2 and 3. For example, the film material can be firmly attached to the surface of the acrylic sheet by applying appropriate pressure to the acrylic sheet with the two lamination rollers, or the double-sided lamination process can be assisted by heating the film material with heat.

[0059] After the acrylic sheet is coated, the first and second film materials have not yet been cut. At this time, the film cutting mechanism is started to cut the film material still attached to the acrylic sheet that has flowed out of the outlet of the first channel, thus completing the double-sided coating operation of a single acrylic sheet.

[0060] In summary, the double-sided laminating device of this application uses a first laminating roller 2 and a second laminating roller 3 spaced apart on the mounting base 1. The two laminating rollers are respectively wound with a first film and a second film for laminating the two opposite surfaces of the product. When the laminating drive 4 drives the first laminating roller 2 and the second laminating roller 3 to move, the first laminating roller 2 and the second laminating roller 3 rotate to transport the product forward. At the same time, the first film and the second film are laminating the opposite surfaces of the product while the product is being transported, thereby realizing synchronous lamination of both sides of the product. After lamination is completed, the film cutting mechanism 5 cuts the film, completing the fully automatic lamination process. Compared with the manual double-sided lamination process, the work efficiency is greatly improved.

[0061] Reference Figures 1 to 3 In some embodiments, the first coating roller 2 and the second coating roller 3 proposed in the embodiments of this application are spaced apart along the vertical direction of the mounting base 1; the double-sided coating device also includes a third coating roller 6 wound with a third film material, the third coating roller 6 being spaced apart on one side of the first coating roller 2 along the product conveying direction and being connected to the coating drive 4 in a transmission connection.

[0062] In this embodiment, the first coating roller 2 and the second coating roller 3 are vertically spaced on the mounting base 1, forming a first channel between them for products (such as acrylic sheets) to pass through. The first coating roller 2 is wound with a first film material, and the second coating roller 3 is wound with a second film material, for simultaneous coating of the upper and lower surfaces of the product.

[0063] The third coating roller 6 is spaced apart on one side of the first coating roller 2 along the product conveying direction (i.e. the direction of product movement in the first channel), and is wound with the third film material and is connected to the coating drive 4 for transmission.

[0064] The coating drive unit 4 is connected to the first coating roller shaft 2, the second coating roller shaft 3 and the third coating roller shaft 6 to provide power and drive each roller shaft to rotate synchronously or in coordination, so as to ensure the stability and consistency of the coating process.

[0065] The third coating roller 6 is positioned along the product conveying direction on one side of the first coating roller 2 (e.g., upstream or downstream of the first channel), and serves as a pre-treatment or post-treatment component in the coating process. Specific functions include:

[0066] Pre-treatment coating: If the third coating roller 6 is located upstream of the first channel, the third film material may cover the product surface (such as the upper surface) before the product enters the first channel to form a pre-coated layer, which is used to enhance the adhesion of subsequent coating, protect the product surface, or add special functions (such as antistatic and scratch-resistant).

[0067] Post-processing coating: If the third coating roller 6 is located downstream of the first channel, the third film material may be applied to the surface of the coated product (such as the upper surface) after double-sided coating is completed, forming an additional protective layer, decorative layer or functional layer (such as waterproof film or optical film).

[0068] For example, in order to make the film coating of the third coating roller 6 stable, a fourth coating roller 6 may be set to correspond to the third coating roller 6, and the fourth coating roller 6 and the second coating roller 6 may be set to be parallel.

[0069] Reference Figures 1 to 3 In some embodiments, the double-sided coating device proposed in this application further includes a transmission assembly 7, and the coating drive 4 is connected to the first coating roller 2, the second coating roller 3 and the third coating roller 6 through the transmission assembly 7.

[0070] Specifically, refer to Figures 1 to 3 In a preferred embodiment, the transmission component 7 proposed in this application includes a drive sprocket 71, a plurality of driven sprockets 72, and a transmission chain 73. The drive sprocket 71 is connected to the output end of the film-coating drive component 4. One end of the first film-coating roller shaft 2, the second film-coating roller shaft 3, and the third film-coating roller shaft 6 is provided with a driven sprocket 72. The transmission chain 73 is meshed with the drive sprocket 71 and each driven sprocket 72.

[0071] In this embodiment, the double-sided coating device of this application adds a transmission component 7 to the original one, which is used to realize the transmission connection between the coating drive 4 and the first coating roller shaft 2, the second coating roller shaft 3 and the third coating roller shaft 6. Specifically, the transmission component 7 is composed of a drive sprocket 71, a plurality of driven sprockets 72 and a transmission chain 73.

[0072] When the film-coating drive 4 is activated, it outputs rotational power to the drive sprocket 71, causing the drive sprocket 71 to rotate.

[0073] The driving sprocket 71 transmits power to the driven sprockets 72 of the first coating roller shaft 2, the second coating roller shaft 3, and the third coating roller shaft 6 via the drive chain 73. The meshing connection of the drive chain 73 ensures that each driven sprocket 72 rotates synchronously or in a coordinated manner, thereby driving the first, second, and third coating roller shafts 6 to rotate at the same speed and in the same direction.

[0074] The product is fed into the first channel (located between the first coating roller 2 and the second coating roller 3) by a conveyor or manually. The first coating roller 2 and the second coating roller 3 rotate under the drive of the driven sprocket 72, releasing the first film material and the second film material respectively.

[0075] The first and second film materials are bonded to the upper and lower surfaces of the product. Through pressure, heat (such as hot press rollers) or other auxiliary mechanisms (such as adhesive or UV curing) applied by the rollers, the film materials are firmly attached to the product surface, completing the double-sided coating.

[0076] In some embodiments, the transmission connection can also be achieved through a configuration of meshing driving gears and driven gears, which is illustrative only and not restrictive.

[0077] Reference Figures 1 to 3 In some embodiments, the double-sided laminating device proposed in this application further includes a first film-feeding roller 8, a second film-feeding roller 9, and a third film-feeding roller 10. The first film-feeding roller 8 and the second film-feeding roller 9 are located above the first laminating roller 2, and the third film-feeding roller 10 is located below the second laminating roller 3; wherein:

[0078] The first film feeding roller 8 is wound with the first film material;

[0079] The second film feeding roller 9 is wound with the second film material, and the second film feeding roller 9 is horizontally spaced from the first film feeding roller 8.

[0080] The third film material is wound on the third film feeding roller 10.

[0081] In this embodiment, the first film feeding roller 8 is located on the upper side of the first film coating roller 2, and is wound with the first film material to provide film material supply to the first film coating roller 2.

[0082] The second film feeding roller 9 is located above the first film coating roller 2 and is horizontally spaced from the first film feeding roller 8. It is wound with the second film material and provides film material supply to the second film coating roller 3.

[0083] The third film-feeding roller 10 is located below the second film-coating roller 3 and is wound with the third film material, providing film material supply to the third film-coating roller 6. For example, when the double-sided film-coating device of this application is installed in a film-coating device, particularly on the base 100 of the film-coating device, the third film-feeding roller 10 can be accommodated within the base 100.

[0084] Reference Figures 1 to 3 In some embodiments, the double-sided laminating device proposed in this application further includes two tensioning components 11, each tensioning component 11 comprising:

[0085] The first lifting drive component 111 is mounted on the mounting base 1;

[0086] The base 112 is located at the output end of the first lifting drive component 111;

[0087] Tensioning shaft 113 is disposed on base 112;

[0088] The first film material is wound around the tensioning shaft 113 of one of the two tensioning components 11 and then wound onto the first coating roller shaft 2, and the second film material is wound around the tensioning shaft 113 of the other of the two tensioning components 11 and then wound onto the second coating roller shaft 3.

[0089] In this embodiment, the first lifting drive 111 is mounted on the mounting base 1 of the device, providing lifting power (such as a cylinder, electric push rod, or servo motor) perpendicular to the product direction for dynamically adjusting the position of the tension shaft 113. The base 112 is connected to the output end of the first lifting drive 111 and moves up and down relative to the mounting base 1 as driven by the first lifting drive 111, serving to support the tension shaft 113. The tension shaft 113 is rotatably mounted on the base 112, with the film material passing over its surface. The first film material is released from the first film feeding roller shaft 8, passes over the tension shaft 113 of one tensioning assembly 11, and is then transferred to the first coating roller shaft 2. The second film material is released from the second film feeding roller shaft 9, passes over the tension shaft 113 of another tensioning assembly 11, and is then transferred to the second coating roller shaft 3.

[0090] The first lifting drive 111 adjusts the length of the membrane material's travel path by controlling the vertical position of the base 112 relative to the mounting base 1, thereby changing the height of the tensioning shaft 113. When the tensioning shaft 113 rises, the membrane material's travel path becomes longer, and the tension increases; when the tensioning shaft 113 falls, the path becomes shorter, and the tension decreases. For example, the tensioning assembly 11 may be equipped with a tension sensor or feedback system to monitor the membrane material tension in real time. The first lifting drive 111 dynamically adjusts the position of the tensioning shaft 113 based on the feedback signal to maintain a constant, optimal tension.

[0091] Reference Figure 1 and Figure 4In some embodiments, the double-sided coating device proposed in this application further includes a film cutting mechanism located on the outlet side of the first channel, the film cutting mechanism including:

[0092] The first transverse drive component 51 is mounted on the mounting base 1;

[0093] The second lifting drive unit 52 is located at the output end of the first transverse drive unit 51;

[0094] The cutting component 53 is located at the output end of the second lifting drive component 52;

[0095] The first lateral drive 51 is used to drive the cutting piece 53 to move in the horizontal direction, and the second lifting drive 52 is used to drive the cutting piece 53 to move in the vertical direction.

[0096] In this embodiment, the first lateral movement drive 51 is mounted on the mounting base 1, either directly or via an intermediate structure, providing horizontal driving force (such as a cylinder, electric slide rail, or servo motor) to drive the cutting piece 53 to move horizontally and adjust the cutting position. The second lifting drive 52 is connected to the output end of the first lateral movement drive 51, providing vertical driving force (such as a cylinder or electric push rod) to drive the cutting piece 53 to move up and down, controlling the cutting depth or position. The cutting piece 53 is mounted on the output end of the second lifting drive 52, specifically a cutting tool (such as a blade, laser cutting head, or rotary blade) for performing the cutting task of the film material or product.

[0097] The first lateral drive 51 drives the second lifting drive 52 and the cutting component 53 to move horizontally, so that the cutting component 53 can be aligned with a specific cutting position after the product is coated, or drive the cutting blade to move laterally to cut the film.

[0098] The second lifting drive 52 drives the cutting component 53 to move up and down vertically, adjusting the distance between the cutting component 53 and the surface of the film or product. When the cutting component 53 descends, it contacts the film or product to perform cutting; when it rises, it moves away from the film or product, preparing for the next cutting or to avoid it.

[0099] The product is fed to the inlet of the first channel by a conveyor or manually. After the product is coated, it leaves the first channel, at which point the film material has not yet been cut. When cutting is required, the film cutting mechanism is activated, the second lifting drive 52 drives the cutting piece 53 to descend, causing the cutting blade to pierce the film material, and the first lateral drive 51 drives the cutting piece 53 to move laterally, so that the cutting piece 53 cuts the first film material and the second film material.

[0100] After the cutting is completed, the second lifting drive 52 drives the cutting piece 53 to rise, and the first lateral drive 51 can move it back to the initial position or adjust it to the next cutting position.

[0101] In some embodiments, the second lifting drive 52 can also be a fine-tuning cylinder that is normally kept fixed, so that the position of the cutting piece in the vertical direction is always kept at the same height. When the height needs to be adjusted, the extension distance of the piston rod of the fine-tuning cylinder can be adjusted to adjust the height of the cutting piece 53.

[0102] Reference Figures 1 to 3 In some embodiments, the double-sided coating device proposed in this application further includes a cleaning component 12 located on the feed inlet side of the first channel. The cleaning component 12 includes:

[0103] The first cleaning roller 121 is rotatably mounted on the mounting base 1;

[0104] The second cleaning roller 122 is rotatably disposed on the mounting base 1 and spaced apart below the first cleaning roller. A second channel corresponding to the first channel is formed between the second cleaning roller 122 and the first cleaning roller 121. The second channel is used for the product to be coated to pass through.

[0105] In this embodiment, the double-sided laminating device of this application is provided with a cleaning component 12, located on one side of the first channel inlet, for cleaning the surface of the product before it enters the first channel for double-sided lamination, in order to remove dust, particles or other impurities and ensure lamination quality. The cleaning component 12 consists of a first cleaning roller 121 and a second cleaning roller 122.

[0106] The first cleaning roller 121 is rotatably mounted on the mounting base 1, located above the cleaning assembly 12, and is used to clean the upper surface of the product. The roller surface may be covered with cleaning material (such as adhesive tape, a brush, or an electrostatic adsorption material) to adsorb or remove surface impurities.

[0107] The second cleaning roller 122 is rotatably mounted on the mounting base 1, located below the first cleaning roller 121, and spaced apart from the first cleaning roller 121 to form a second channel for the product to be coated to pass through. The second cleaning roller 122 is used to clean the lower surface of the product, and its structure is similar to that of the first cleaning roller 121.

[0108] The second channel, located between the first cleaning roller 121 and the second cleaning roller 122, is a passage for the product to be coated. The channel width is adapted to the product thickness to ensure stable passage during cleaning. For example, the interval between the two rollers can be adjusted to accommodate products of different thicknesses. For instance, one of the first cleaning roller 121 and the second cleaning roller 13 can be slidably connected to a groove on the mounting base via a pulley. Then, a driving component such as a pressure cylinder is used to drive the roller slidably connected to the mounting base to move towards the other roller.

[0113] The gripper 203 is located at the output end of the flipping drive 202;

[0114] The flipping drive 202 is used to drive the gripper 203 to transfer the product to the receiving conveyor belt 201, and the receiving conveyor belt 201 transports the product into the first channel.

[0115] In this embodiment, the receiving conveyor belt 201 is installed on the base 100 and is used to receive and transport products. The receiving conveyor belt 201 is typically a belt conveyor mechanism with a flat surface and a certain amount of friction or adsorption to stably transport products, and it connects to the first channel inlet of the double-sided coating device.

[0116] The flipping drive 202 is mounted on the base 100 and located on the side of the receiving conveyor belt 201 facing away from the double-sided film coating device (i.e., the side away from the first channel entrance, usually the starting end of feeding), providing rotation or flipping power (such as a servo motor, pneumatic rotary cylinder or robotic arm drive system).

[0117] The gripper 203 is connected to the output end of the flipping drive 202, and is specifically a gripping tool (such as a suction cup, gripper or magnetic adsorption device) used to grip the product and transfer it to the receiving conveyor belt 201.

[0118] Products to be coated may be stacked at the starting position of the feeding device 200 (such as the stacking area or raw material storage area).

[0119] The flip drive 202 is activated, driving the gripper 203 to move to the product stacking position. The gripper 203 firmly grasps a single product using a suction cup, clamp, or other mechanism.

[0120] The flip drive 202 rotates or moves (e.g., flips 180°) to transfer the gripper 203 along with the product to above the receiving conveyor belt 201. The gripper 203 releases the product, placing it stably on the surface of the receiving conveyor belt 201.

[0121] The flipping function of the flipping drive 202 may be used to adjust the product posture (such as flipping the product from horizontal to a specific angle, or from the reverse side to the front side) to ensure that the product enters the subsequent process in the correct orientation and position.

[0122] The receiving conveyor belt 201 starts and smoothly transports the product from the feeding position to the first channel entrance of the double-sided coating device through belt drive.

[0123] If the equipment includes a cleaning component 12, the receiving conveyor belt 201 may first transport the product to the second channel of the cleaning component 12 (formed by the first cleaning roller 121 and the second cleaning roller 122) for surface cleaning, and then enter the first channel.
