Description

Technical Field

[0002] In the field of wallpaper production and processing, coating, hot stamping and embossing are important technological processes to enhance the aesthetics and added value of wallpaper. Traditional wallpaper coating, hot stamping and embossing production devices have many limitations in practical applications.

[0003] In the embossing process, the traditional method mostly uses an embossing roller for embossing, and the surface of the embossing roller is provided with embossing patterns. However, the embossing roller is relatively large in size, which not only occupies a large amount of production space, making the layout of production equipment less compact and increasing the cost of the production site, but also makes it extremely difficult to replace the embossing roller when facing different embossing requirements. Due to the limitations of the volume and weight of the embossing roller, the replacement process requires a large amount of time and manpower, seriously affecting production efficiency and flexibility.

[0004] In addition, in the traditional production process, the coating, hot stamping and embossing processes of wallpaper are often carried out separately, and the connection between each process is not smooth enough, resulting in the inability to continuously process the wallpaper. This discontinuous production method not only reduces production efficiency, but also increases the operation complexity and error rate in the production process, making the production cost of wallpaper remain high and unable to meet the market's demand for high-efficiency and high-quality production of wallpaper products.

[0024] Please refer to Figures 1 to 2 , an embodiment of the present application provides a wallpaper 8 coating and hot stamping embossing production device, including a working platform 1, a coating mechanism 2, an electric heating plate 3, an embossing mechanism 4, and a traction mechanism 5. Among them, the working platform 1 is arranged on the frame. The coating mechanism 2 is rotatably arranged at one end of the working platform 1, and the coating mechanism 2 is used for coating the wallpaper 8 on the working platform 1. The electric heating plate 3 is built in the middle of the working platform 1, and the heating plate is used for heating and hot stamping the coated wallpaper 8. The embossing mechanism 4 is arranged at the other end of the working platform 1. The embossing mechanism 4 includes a gantry 41, a first hydraulic rod 42, an embossing mounting frame 43, a first tensioning roller 44, a rotation power unit 45, a second hydraulic rod 46, a tensioning mounting frame 47, a second tensioning roller 48, and an embossing belt 49; the gantry 41 is fixed on the working platform 1; the first hydraulic rod 42 is arranged perpendicular to the horizontal plane, and its cylinder body is fixed on the gantry 41; the embossing mounting frame 43 is fixed on the piston rod of the first hydraulic rod 42; the first tensioning roller 44 is rotatably arranged on the embossing mounting frame 43, and the surface of the first tensioning roller 44 is provided with a tooth structure; the rotation power unit 45 is arranged on the embossing mounting frame 43, and the rotation power unit 45 drives the first tensioning roller 44 to rotate; the second hydraulic rod 46 is arranged perpendicular to the horizontal plane, and its cylinder body is fixed on the gantry 41; the tensioning mounting frame 47 is fixed on the piston rod of the second hydraulic rod 46; the second tensioning roller 48 is rotatably arranged on the tensioning mounting frame 47, and the surface of the second tensioning roller 48 is also provided with a tooth structure; the inner surface of the embossing belt 49 is provided with a rack structure, and both ends of the embossing belt 49 are fitted on the first tensioning roller 44 and the second tensioning roller 48. The outer surface of the embossing belt 49 is provided with raised embossing patterns, and the wallpaper 8 passes through between the embossing belt 49 and the working platform 1. The traction mechanism 5 is arranged on one side of the working platform 1, and the traction mechanism 5 is used for traction of the wallpaper 8. Both the traction mechanism 5 and the coating mechanism 2 are connected to the first tensioning roller 44 through a transmission device, so that the running speeds of the embossing belt 49, the traction mechanism 5, and the coating mechanism 2 are the same.

[0025] The present invention conveys the wallpaper 8 to be coated, hot stamping and embossed through the traction mechanism 5, so that the wallpaper 8 successively passes through the coating mechanism 2, the electric heating plate 3, and the embossing mechanism 4. First, the wallpaper 8 is coated by the coating mechanism 2, then the wallpaper 8 is heated and hot stamped by the electric heating plate 3, and finally, the embossing mechanism 4 performs embossing. After the embossing is completed, a winding device can be set to wind the processed wallpaper 8, enabling the wallpaper 8 to continuously perform the coating, hot stamping, and embossing processes, thereby improving efficiency. When performing embossing, the piston rods of the first hydraulic rod 42 and the second hydraulic rod 46 extend, causing the embossing mounting frame 43 and the tensioning mounting frame 47 to descend. As a result, the first tensioning roller 44, the second tensioning roller 48, and the embossing belt 49 descend until the embossing belt 49 presses tightly against the wallpaper 8 on the working platform 1 below. At this time, the rotation power unit 45 (specifically, it can be a motor) operates, driving the first tensioning roller 44 to rotate, and then causing the embossing belt 49 to operate. Since the embossing belt 49, the traction mechanism 5, and the coating mechanism 2 are all driven by the rotation power unit 45 and have the same operating speed, when the embossing belt 49 operates, the traction mechanism 5 traction the wallpaper 8 to move at the same speed. Under the pressure of the first hydraulic rod 42, the embossing pattern on the outer surface of the embossing belt 49 is embossed on the wallpaper 8, thereby realizing continuous embossing of the wallpaper 8. By setting the embossing belt 49 for embossing, compared with the traditional method of using an embossing roller (with an embossing pattern set on the surface of the embossing roller) for embossing, the embossing method of the embossing belt 49 can replace the embossing belt 49 with different embossing patterns according to different embossing requirements. However, the traditional embossing roller is relatively large in volume, occupies a large amount of space, and is not easy to replace. In this application, the embossing belt 49 replaces the embossing roller, replacing the large-volume embossing roller with a strip-shaped embossing belt 49, which occupies less space and is convenient to replace.

[0026] In addition, the coating mechanism 2 and the embossing mechanism 4 press the wallpaper 8 tightly onto the working platform 1, enabling the wallpaper 8 between them to closely adhere to the working platform 1, thereby enabling the electric heating plate 3 to better heat and hot stamp the coated wallpaper 8.

[0027] Optionally, connecting pins (similar to the connection method of a chain) are provided at both the head and tail ends of the embossing belt 49. The embossing belt 49 is formed into an annular structure by inserting the connecting pins. When it is necessary to disassemble and install the embossing belt 49, simply loosen / insert the connecting pins to disassemble / install the embossing belt 49.

[0028] In one embodiment, the traction mechanism 5 includes a driving roller 51 and a driven roller 52. The driving roller 51 and the driven roller 52 are rotatably arranged on the frame. The driving roller 51 is connected to the first tensioning roller 44 through a transmission device. The driving roller 51 and the driven roller 52 are meshed through a gear set. The wallpaper 8 is located between the driving roller 51 and the driven roller 52. The driving roller 51 and the driven roller 52 rotate in opposite directions, and the wallpaper 8 is located between the driving roller 51 and the driven roller 52. The friction force between the driving roller 51, the driven roller 52, and the wallpaper 8 is used to drive the wallpaper 8 to move.

[0029] In one embodiment, the transmission device includes a transmission wheel and a transmission belt 61, and both ends of the transmission belt 61 are mounted on the transmission wheel. Specifically, the diameter ratio of the first tensioning roller 44 to the driving roller 51 is the same as the diameter ratio of the transmission wheels provided for the two, so that the linear velocity of the imprinting belt 49 on the first tensioning roller 44 is the same as the linear velocity of the driving roller 51 (i.e., the linear velocity of the wallpaper 8). The same applies to the transmission wheels on the coating mechanism 2.

[0030] In order to make it difficult for the imprinting belt 49 to be restricted by the transmission device when adjusting its position up and down, in one embodiment, an automatic tensioning mechanism 7 is further included. The automatic tensioning mechanism 7 includes a connecting rod 71, a tensioning rod 72, and a first elastic member 73. The top of the connecting rod 71 is rotatably connected to the gantry 41. The tensioning rod 72 is rotatably arranged at the bottom of the connecting rod 71, and the tensioning rod 72 is in sliding fit with the transmission belt 61. One end of the first elastic member 73 is fixed to the gantry 41, and the other end of the first elastic member 73 is connected to the connecting rod 71. The first elastic member 73 applies an elastic force to the connecting rod 71 and the tensioning rod 72, so that the tensioning rod 72 presses down to tension the transmission belt 61.

[0031] As Figure 1 shown, under the elastic force of the first elastic member 73, the automatic tensioning mechanism 7 presses down the transmission belt 61 to make the transmission belt 61 taut. When it is necessary to adjust the imprinting belt 49 upward, the first hydraulic rod 42 and the second hydraulic rod 46 contract, causing the first tensioning roller 44 to move upward. At this time, the distance between the first tensioning roller 44 and the driving roller 51 / coating mechanism 2 becomes larger, and the straightening force acting on the transmission belt 61 towards both ends becomes larger. Under the action of the straightening force, the transmission belt 61 overcomes the elastic downward pressure of the first elastic member 73, causing the first elastic member 73 to elongate. At the same time, the connecting rod 71 rotates upward, and the tensioning rod 72 moves upward, straightening the originally downward-bent upper part of the transmission belt 61 to adapt to the increase in the distance between the first tensioning roller 44 and the driving roller 51 / coating mechanism 2. Conversely, when adjusting the imprinting belt 49 downward to make the distance between the first tensioning roller 44 and the driving roller 51 / coating mechanism 2 smaller, at this time, the connecting rod 71 and the tensioning rod 72 rotate downward, further pressing down the transmission belt 61 to keep the transmission belt 61 taut. Thus, the automatic tensioning of the transmission belt 61 is realized to adapt to the up and down adjustment of the imprinting belt 49.

[0032] As Figures 3 - 4As shown, in one embodiment, the coating mechanism 2 includes a coating cylinder 21, a hollow rotating shaft 22, and a number of automatic closing mechanisms 23. Among them, the cylindrical surface of the coating cylinder 21 is provided with a hollow-out structure 211, and the hollow-out structure 211 is the pattern to be coated. The coating cylinder 21 is filled with the coating used for coating. The hollow rotating shaft 22 is rotatably arranged on the working platform 1. The hollow rotating shaft 22 is connected to the first tension roller 44 through a transmission device. One end of the hollow rotating shaft 22 is connected to the coating supply pipe 24 through a sealed rotating connection device 25. The coating cylinder 21 is coaxially arranged on the hollow rotating shaft 22, and a discharge port is provided on the hollow rotating shaft 22, and the discharge port is located inside the coating cylinder 21. The automatic closing mechanisms 23 are evenly arranged around the inner wall of the coating cylinder 21. The automatic closing mechanisms 23 automatically close the hollow-out structure 211, and only the hollow-out structure 211 in the coating area at the bottom of the coating cylinder 21 is opened.

[0033] During coating, the coating supply pipe 24 transports the coating into the hollow rotating shaft 22 through the sealed rotating connection device 25. Then, the coating enters the coating cylinder 21 through the discharge port on the hollow rotating shaft 22. The rotation power unit 45 drives the first tension roller 44 to rotate. Since the hollow rotating shaft 22 is connected to the first tension roller 44 through a transmission device, the hollow rotating shaft 22 and the coating cylinder 21 are driven to rotate. During the rotation of the coating cylinder 21, the automatic closing mechanism 23 at the bottom (coating area) of the coating cylinder 21 is opened, so that the coating in the coating cylinder 21 can be output from the hollow-out structure 211 at this place and then coated on the lower wallpaper 8. Due to the rotation of the coating cylinder 21, the respective automatic closing mechanisms 23 provided on the inner wall of the coating cylinder 21 are sequentially opened, and the pattern of the hollow-out structure 211 is coated on the lower wallpaper 8. When an automatic closing mechanism 23 rotates away from the bottom position, the automatic closing mechanism 23 immediately closes the hollow-out structure 211 at this place to prevent the coating from flowing out from other positions except the bottom (coating area) of the coating cylinder 21. Furthermore, the pattern of the hollow-out structure 211 can be designed according to requirements to coat a specific pattern on the wallpaper 8.

[0034] As Figure 5As shown, in one embodiment, the automatic closing mechanism 23 includes a guide rod 231, a control rod 232, a sealing plate 233, and a second elastic member 234. The guide rod 231 is disposed on the side surface of the coating cylinder 21 along the radial direction of the coating cylinder 21. The end of the control rod 232 extends outward from the cylindrical surface of the coating cylinder 21, and the control rod 232 is slidably engaged with the guide rod 231 and the coating cylinder 21. The sealing plate 233 is fixed to the control rod 232, and the sealing plate 233 is an arc-shaped plate, and the outer surface of the sealing plate 233 has the same curvature as the inner surface of the coating cylinder 21. One end of the second elastic member 234 is connected to the coating cylinder 21, and the other end of the second elastic member 234 is connected to the control rod 232. The second elastic member 234 applies an elastic force to the control rod 232 so that the control rod 232 extends outward, and the sealing plate 233 presses against the inner surface of the coating cylinder 21 to close the hollow structure 211.

[0035] When a certain automatic closing mechanism 23 rotates to the bottom of the coating cylinder 21 along with the coating cylinder 21 (the bottom of the outer surface of the coating cylinder 21 is in close contact with the wallpaper 8), the control rod 232 abuts against the working platform 1, so that the control rod 232 retracts upward (toward the inside of the coating cylinder 21) against the elastic force of the second elastic member 234. Since the sealing plate 233 is fixed to the control rod 232, the sealing plate 233 synchronously moves toward the center of the coating cylinder 21, so that the sealing plate 233 that was originally in close contact with the inner wall of the coating cylinder 21 separates from the inner wall of the coating cylinder 21. As a result, the hollow structure 211 on the coating cylinder 21 at this position communicates with the outside, and the paint in the coating cylinder 21 can be output outward from the hollow structure 211 at this position, and a coating having the same shape as the hollow structure 211 is applied to the wallpaper 8 below.

[0036] When the automatic closing mechanism 23 rotates away from the bottom along with the coating cylinder 21, the control rod 232 disengages from the working platform 1, so that the control rod 232 moves outward under the resilience of the second elastic member 234. As a result, the sealing plate 233 presses against the inner wall of the coating cylinder 21 again, and under the resilience of the second elastic member 234, the hollow structure 211 at this position is tightly closed, preventing the paint in the coating cylinder 21 from leaking.

[0037] In one embodiment, the second elastic member 234 is a spring, and the second elastic member 234 is sleeved on the guide rod 231. By sleeving the second elastic member 234 on the guide rod 231, the compression / rebound direction of the second elastic member 234 is guided and limited by the guide rod 231, making the closing / opening process of the automatic closing mechanism 23 more stable.

[0038] In one embodiment, the sealed rotating connection device 25 includes a main body portion 251 and a mechanical seal mechanism 252. The main body portion 251 has a hollow structure. One end of the main body portion 251 is fixedly and sealingly connected to the hollow rotating shaft 22. A connection hole is formed at the other end of the main body portion 251. The coating replenishment pipe 24 is rotatably connected to the connection hole of the main body portion 251, and a mechanical seal mechanism 252 is provided between the coating replenishment pipe 24 and the main body portion 251. The main body portion 251 rotates with the hollow rotating shaft 22. The main body portion 251 and the hollow rotating shaft 22 can be provided as an integral structure. The coating enters the main body portion 251 from the coating replenishment pipe 24, and then enters the hollow rotating shaft 22 from the main body portion 251 to replenish the coating for the coating cylinder 21. The mechanical seal mechanism 252 provided between the coating replenishment pipe 24 and the main body portion 251 can achieve a sealing effect and prevent the coating from leaking from the connection position between the main body portion 251 and the coating replenishment pipe 24. The mechanical seal mechanism 252 is a conventional device, and its specific structure will not be described in detail here.

[0039] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
