Abstract
Description
Technical Field
[0001] This utility model belongs to the field of decorative paper production technology, specifically relating to a melamine paper hot press. Background Technology
[0002] Melamine-impregnated paper, also known as melamine-impregnated film paper or melamine paper, is produced through a crucial step: the lamination of the base paper (plain base paper) and the face paper (printed decorative paper). This process determines the quality of the final melamine-impregnated paper product.
[0003] Currently, the traditional production method uses a platen hot press, where the face paper and backing paper are pressed together by an upper and lower platen. In operation, the paper needs to be cut to a certain length beforehand, and then the face and backing papers are manually overlapped and placed into the hot press for heat pressing. This method has several drawbacks: Firstly, due to the limited size of the hot pressing plates, the paper needs to be pre-cut, which restricts the length and width of the melamine paper, making it impossible to obtain large-format sheets and affecting the application of the product in scenarios with large size requirements. Secondly, manual feeding is not only labor-intensive but also inefficient, making it difficult to meet the needs of large-scale production. Summary of the Invention

[0009] Preferably, the positioning roller unit is provided with cylinder three, at least two cylinder three are provided, and are provided at the bottom of the two side walls of the frame. The cylinder three is connected to the mounting plate. The two ends of the rotating shaft of the roller three are respectively connected to the mounting plate. The cylinder three drives the roller three to move away from or towards the center of the triangle by pulling down the mounting plate to realize the tension adjustment of the steel strip.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.
[0029] In the description of the embodiments of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 2 The orientations or positional relationships shown are only for the purpose of facilitating the description of the embodiments of this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0032] In one embodiment of this utility model, such as Figure 1 , 2 As shown, a melamine paper hot press is provided, including a frame 10, a paper transport unit 20, a hot pressing device 30, and a winding device 40.
[0033] like Figure 2 As shown, the frame 10 includes two parallel side plates. The frame 10 is fixed with a paper transport unit 20, a hot pressing device 30, and a winding device 40 in sequence along the paper feeding direction. The end of the frame 10 with the paper transport unit 20 is the left end.
[0034] The paper transport unit 20 includes a bottom paper roller 21, a guide roller 22, and a top paper roller 23. The bottom paper roller 21 is fixedly located at the leftmost end of the frame 10. The bottom paper roller 21 is connected to the frame 10 and can rotate relative to the frame 10. A bottom paper is sleeved on the bottom paper roller 21.
[0035] Multiple guide rollers 22 are arranged at varying heights from left to right on the frame 10 to the right of the bottom paper roller 21, and to the right of the hot pressing device 30. Preferably, there are three guide rollers 22. The first guide roller 22 is higher than the bottom paper roller 21 on the frame 10, the second guide roller 22 is lower than the first guide roller 22 but higher than the bottom paper roller 21, and the third guide roller 22 is higher than the first guide roller 22. The bottom paper is sequentially wound around the multiple guide rollers 22. This design of the positional relationship of the guide rollers 22 changes the position of the bottom paper on the guide rollers. The wrap angle and stroke of guide rollers 22 increase tension, ensuring the backing paper maintains appropriate tension and preventing problems such as wrinkles, deviation, or breakage due to insufficient tension. Multiple guide rollers 22 at different heights ensure the backing paper is smoothly conveyed along a predetermined trajectory and accurately enters the hot pressing device 30 for bonding, ensuring an orderly production process, improving product quality and production stability. Simultaneously, the multiple guidance and adjustments of the backing paper by guide rollers 22 at different heights can, to some extent, stretch the backing paper, reducing any minor unevenness that may exist within the paper itself, allowing it to enter the hot pressing device in a flatter state and improving the hot pressing bonding effect. The wrap angle refers to the central angle corresponding to the contact arc between the paper and the roller shaft.
[0036] The face paper roller 23 is fixedly mounted on the frame 10 and located above the third guide roller 22. Sufficient distance is maintained between the bottom point of the face paper roller 23 and the third guide roller 22 for the face paper and back paper to pass through. The height of the bottom point of the face paper roller 23 is lower than the height of the apex of the roller shaft closest to the face paper roller 23 in the hot pressing device 30. The position of the face paper roller 23 ensures that the face paper maintains appropriate tension when entering the hot pressing device, preventing it from shifting or wrinkling during hot pressing, ensuring consistent hot pressing results. It also increases the contact area and contact time between the face paper and the hot pressing device 30, resulting in a tighter bond between the face paper and back paper, improving bonding quality, and reducing defects such as bubbles and wrinkles.
[0037] The hot pressing device 30 includes a patterned roller 31, a steel strip 32, and a positioning roller unit 33. The patterned roller 31 is fixedly connected to the frame 10 and is rotatable relative to the frame 10. The surface of the patterned roller 31 is decorated with a pattern that gives the melamine paper a specific decorative pattern. A heating device is installed inside the patterned roller 31, which can be electrically heated or heated with steam to generate the temperature required for the backing paper and face paper to be pressed together. A steel strip 32 is located below the patterned roller 31, and the patterned roller 31 and the steel strip 32 are pressed against each other. The upper surface of the steel strip 32 presses against the lower roller surface of the patterned roller 31, and the patterned roller 31 and the steel strip 32 form a wrap angle. The central angle corresponding to the contact arc between the patterned roller 31 and the steel strip 32 is 30-170 degrees.
[0038] The steel strip 32 is a stainless steel annular strip. The steel strip 32 is sleeved on the positioning roller unit 33. The surface of the steel strip 32 is flat and smooth, and it is used to support the paper to achieve pressing with the patterned roller (31).
[0039] The face paper is adhered to the back paper and between the patterned roller (31) and the steel strip (32).
[0040] The positioning roller unit 33 includes a first adjusting mechanism 331, a roller shaft 332, a second adjusting mechanism 333, a roller shaft 334, a roller shaft 335, a cylinder 336, a cylinder 337, a cylinder 338, and a mounting plate 339.
[0041] The rollers 332, 334, and 335 are rotatably mounted relative to the frame 10. The center points of the rollers 332, 334, and 335 form an inverted triangle. The steel strip 32 surrounds the rollers 332, 334, and 335. The patterned roller 31 is located above the rollers 332 and 334.
[0042] The two ends of the rotating shaft of the roller 332 are respectively connected to the side plate of the frame 10 through the first adjustment mechanism 331. The first adjustment mechanism 331 has a slide rail assembly, which drives the roller 332 to move away from or closer to the center of the triangle to adjust the tension of the steel strip 32. The cylinder 336 is fixed in the first adjustment mechanism 331, located at both ends of the roller 332, and connected to the roller 332. The cylinder 336 causes the roller 332 to move along the inclined direction of the first adjustment mechanism 331 towards the patterned roller through the lifting movement.
[0043] The two ends of the rotating shaft of the second roller 334 are respectively connected to the side plate through the second adjustment mechanism 333. The second adjustment mechanism 333 has a slide rail assembly, which drives the second roller 334 to move away from or closer to the center of the triangle to adjust the tension of the steel strip 32. The second cylinder 337 is fixed in the second adjustment mechanism 333, located at both ends of the second roller 334, and connected to the second roller 334. The second cylinder 337 causes the second roller 334 to move along the inclined direction of the second adjustment mechanism 333 towards the patterned roller through the lifting movement.
[0044] At least two cylinders 338 are provided at the bottom of both side walls of the frame 10. A mounting plate 339 is connected to each cylinder 338. The two ends of the rotating shaft of the roller 335 are respectively connected to the mounting plate 339. The cylinders 338 drive the roller 335 to move away from or towards the center of the triangle by pulling down the mounting plate 339 to adjust the tension of the steel strip 32.
[0045] The slide rail assemblies in the first adjustment mechanism 331 and the second adjustment mechanism 333 are parallel to each other and inclinedly fixed on the inner walls of both sides of the frame 10. This allows the steel strip to remain taut under the interaction of roller 1 332, roller 2 334 and roller 3 335. Meanwhile, roller 2 334 moves closer to the patterned roller 31 under the lifting action of cylinder 2 337. Roller 2 334 applies pressure to the patterned roller 31, so that the pressure on the bottom paper and the top paper is greater when they pass between the patterned roller 31 and roller 2 334.
[0046] The tilt angle between the slide rail assembly in the first adjustment mechanism 331 and the horizontal plane is 30-60 degrees; the tilt angle between the slide rail assembly in the second adjustment mechanism 333 and the horizontal plane is 30-60 degrees. Preferably, the tilt angle between the slide rail assembly in the first adjustment mechanism 331 and the horizontal plane is 45 degrees; the tilt angle between the slide rail assembly in the second adjustment mechanism 333 and the horizontal plane is 45 degrees.
[0047] The positioning roller unit 33 is connected to a drive device that drives its rotation. The positioning roller unit 33 drives the steel belt 32 to move. The drive device is connected to any one of roller shafts 332, 334, and 335, driving its rotation to drive the steel belt 32 to rotate. The surface of the roller shaft connected to the drive device is provided with a rubber layer to increase the friction with the steel belt 32 and ensure that the roller shaft can drive the steel belt 32 to rotate normally. Preferably, roller shaft 335 is connected to the drive device, which is a servo motor that drives roller shaft 335 to rotate through a transmission chain or other transmission components. The surface of roller shaft 335 is provided with a rubber layer to increase the friction with the steel belt 32 and ensure that the roller shaft can drive the steel belt 32 to rotate normally.
[0048] With the arrangement of rollers 332, 333, and 334, and the pressing action of the patterned roller 31 against the steel strip 32, the steel strip 32 is kept taut. This ensures that when the base paper and face paper are passed between the patterned roller 31 and the steel strip 32, they maintain sufficient contact area with the patterned roller 31 and the steel strip 32, and receive sufficient pressure. Simultaneously, while the steel strip 32 remains taut, the motor drives roller 333 to rotate, which in turn drives the steel strip 32 to rotate. This causes the patterned roller 31 and the positioning roller unit 33 to press the base paper and face paper together while simultaneously moving the base paper and face paper to the right side of the frame 10.
[0049] The winding device 40 includes a cooling roller unit 41, a traction roller assembly 42, a water spray head 43, a water tank 44, a lifting platform 45, an anilox roller 46, a scraper 47, a guide roller 48, and a winding roller 49.
[0050] The cooling roller unit 41 includes a first cooling roller 411, a second cooling roller 412, and a third cooling roller 413. Each cooling roller is equipped with a cooling device, and the cooling roller cools the pressed bottom paper and top paper that are wound around the cooling roller.
[0051] Cooling roller 411 is mounted on frame 10 via bearings and is located to the right of roller 333. The height of cooling roller 411 on frame 10 is lower than that of roller 333, which allows the bottom paper and face paper to better adhere to the steel strip 32. Cooling roller 412 is located at the same horizontal height to the right of cooling roller 411. Cooling roller 413 is located below cooling roller 412 and is adjacent to cooling roller 412. After the bottom paper and face paper are pressed together, they are wound from above roller 333, below cooling roller 411, onto cooling roller 412, and then onto cooling roller 413. Finally, they enter the traction roller group 42 via the right side of cooling roller 413.
[0052] The positional relationship of cooling roller 1 (411), cooling roller 2 (412), and cooling roller 3 (413) ensures that the pressed bottom paper and top paper can fully contact each cooling roller, thus ensuring the cooling effect.
[0053] The traction roller assembly 42 is fixed on the frame 10, located to the right of the cooling roller unit 41, and its height on the frame 10 is higher than that of the cooling roller unit 41. The traction roller assembly 42 is composed of two rollers arranged vertically and parallel to each other. The two rollers are rubber rollers and are tangentially arranged. The lower roller rotates clockwise under the drive of the motor. The bottom paper and the top paper are located between the two rollers. The bottom paper and the top paper move to the right under the traction of the traction roller assembly 42.
[0054] A water spray head 43 is provided on the right side of the traction roller assembly 42. The water spray head 43 is located below the bottom paper and serves to spray liquid materials such as softener onto the bottom paper.
[0055] A water tank 44 is located below the water spray head 43. A lifting mechanism 45, capable of raising and lowering the water tank 44, is located at the bottom of the water tank 44. An anilox roller 46 is located to the right of the water spray head 43. The apex of the anilox roller 46 is on the same horizontal plane as the apex of the lower roller in the traction roller assembly 42, ensuring that the pressed base paper and face paper between the traction roller assembly 42 and the anilox roller 46 are in a horizontal state. A doctor blade 47 is tangentially located to the right of the anilox roller 46. A guide roller 48 is located to the right of the doctor blade 47, and a take-up roller 49 is located to the right of the guide roller 48. The take-up roller 49 rotates under the drive of a motor (not shown). After the pressed base paper and face paper pass over the guide roller 48, they are wound up by the take-up roller 49, completing the production of the melamine paper.
[0056] The working principle of this utility model is as follows: In use, the bottom paper is placed on the bottom paper roller 21, guided by multiple guide rollers 22, and passes between the patterned roller 31 and the steel strip 32. The top paper is guided by the top paper roller 23 and also passes between the patterned roller 31 and the steel strip 32. Then it is wound on the cooling roller unit 41, passes through the traction roller group 42, and is wound on the take-up roller 49 via the anilox roller 46 and the guide roller 48. When the face paper and the back paper pass between the patterned roller 31 and the steel strip 32, the face paper is above the back paper. Cylinder 1 336 and cylinder 2 337 cause roller 1 332 and roller 2 334 to move along the first adjusting mechanism 331 and the second adjusting mechanism 333 respectively in the direction of the patterned roller 31. Cylinder 338 causes roller 335 to move downward. The patterned roller 31 presses against the steel strip 32, increasing the contact area between the steel strip 32 and the patterned roller 31, roller 1 332, and roller 2 334. At the same time, under the action of cylinder 1 336, the steel strip sleeved on roller 1 332, roller 2 334, and roller 335 is kept taut. Roller 335 drives the steel strip 32 to rotate, and the patterned roller 31 heats up, pressing the back paper and the face paper together.
[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
