Description

Technical Field

[0001] This utility model belongs to the field of decorative paper production technology, specifically relating to a melamine paper pressing machine. Background Technology

[0002] Melamine-impregnated paper, also known as melamine paper, involves several key production steps, including the lamination of the base paper (plain base paper) and the face paper (printed decorative paper) and the embossing of the laminated melamine paper.

[0003] Currently, traditional production processes primarily utilize plate heat presses to bond the face paper and backing paper. Operating a plate heat press requires pre-cutting the paper to a specific length, then manually overlapping the face and backing papers before feeding them into the heat press. This method is not only cumbersome and labor-intensive, but also prone to inconsistent product quality due to variations in manual operation. After heat pressing, the bonded melamine-impregnated paper must be manually transferred to an embossing machine.

[0004] In the embossing process, embossing machines use patterned rollers to emboss the surface of melamine paper. However, with the increasing diversification of market demand, manufacturers have to equip themselves with various patterned rollers to meet the demand for different patterned melamine paper. The manufacturing process for these patterned rollers is complex and costly. Even more challenging is the varying market demand for different patterned melamine paper; some patterns have high demand, while others have relatively low demand. This puts manufacturers in a dilemma regarding the configuration of patterned rollers: if they purchase a large number of different patterned rollers to meet the market's demand for all categories, the cost of some rollers increases due to their low usage frequency; if they reduce the variety of patterned rollers they equip, they will struggle to cope with the diverse market demands and may lose market share. Utility Model Content

[0005] The purpose of this invention is to provide a melamine paper pressing machine, which aims to solve the technical problems of low production efficiency and high cost of existing melamine paper pressing machines.

[0006] To achieve the above objectives, this utility model provides a melamine paper pressing machine, including a fixed frame with two parallel side plates. A bottom paper roller for fixing the bottom paper is provided in the fixed frame. A first roller unit and a second roller unit are provided at the end of the fixed frame away from the bottom paper roller. The first roller unit includes a lifting mechanism, a rubber roller, and a driving mechanism. At least two lifting mechanisms are respectively disposed on both sides of the fixed frame and fixed within it. The rubber roller is rotatably mounted on the lifting mechanism, and the driving mechanism is connected to the rubber roller to drive its rotation. The second roller unit is located above the first roller unit and includes a mounting plate and a patterned roller. The patterned roller is equipped with a heating device for generating heat. The patterned roller is fixed in the fixed frame and pressed against the rubber roller. The face paper is adhered to the bottom paper and between the patterned roller and the rubber roller. Multiple mounting plates are provided at both ends of the patterned roller and fixed in the fixed frame, so that the patterned roller is fixed in the fixed frame via the mounting plates.

[0007] Preferably, the surface of the patterned roller is provided with a texture for pressing patterns onto melamine paper.

[0008] Preferably, the mounting plate is detachably connected to the fixing frame by bolts.

[0009] Preferably, guide roller one and guide roller two are provided between the patterned roller and the bottom paper roller. Guide roller one is adjacent to the bottom paper roller and has the same height. Guide roller two is adjacent to the first roller unit, and its axis is on the same horizontal plane as the axis of the rubber roller.

[0010] Preferably, the first roller unit further includes a lifting mechanism, at least two of which are respectively disposed on both sides of the fixed frame and located below the patterned roller, and the lifting end of the lifting mechanism is connected to the patterned roller.

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.

[0030] In one embodiment of this utility model, such as Figure 1-4 As shown, a melamine paper pressing machine is provided, including a fixed frame 10, a bottom paper roller 20, a first roller unit 30, and a second roller unit 40. The fixed frame 10 includes two side plates arranged parallel to each other. The fixed frame 10 is used to support and fix the bottom paper roller 20, the first roller unit 30, and the second roller unit 40.

[0031] like Figure 1 As shown, the fixed frame 10 has one end that fixes the bottom paper roller 20, which is the left end of the fixed frame 10. The first roller unit 30 and the second roller unit 40 are located on the right end of the fixed frame 10. The bottom paper roller 20 has both ends located on the two side plates of the fixed frame 10 and rotates relative to the fixed frame 10. The bottom paper is sleeved on the bottom paper roller 20. The rotation of the bottom paper roller 20 completes the release of the bottom paper.

[0032] like Figure 4As shown, guide roller 1 21 and guide roller 22 are provided between the bottom paper roller 20 and the first roller unit 30. Guide roller 1 21 is arranged adjacent to the bottom paper roller 20, and the height of guide roller 1 21 and bottom paper roller 20 in the fixing frame 10 is the same. Guide roller 22 is arranged adjacent to the first roller unit 30. The axis of guide roller 22 is located on the same horizontal plane as the axis of the rubber roller 32 in the first roller unit 30, so as to increase the contact area between the bottom paper and the rubber roller 32. The bottom paper passes from the bottom of the bottom paper roller 20, through the top of guide roller 1 21, and then through the bottom of guide roller 22, and enters the first roller unit 30. Through the arrangement of guide roller 1 21 and guide roller 2 22, the contact area between the bottom paper and the rubber roller in the first roller unit 30 is increased while maintaining the tension of the bottom paper.

[0033] The first roller unit 30 includes a lifting mechanism 31, a rubber roller 32, and a driving mechanism 33. Two lifting mechanisms 31 are respectively disposed on both sides of the fixed frame 10 and fixed within the fixed frame 10. The rubber roller 32 is rotatably mounted on the lifting mechanism 31. The driving mechanism 33 is connected to the rubber roller 32 to drive its rotation. The lifting mechanism 31 can be a hydraulic cylinder. The top of the piston rod of the hydraulic cylinder is rotatably connected to both ends of the rubber roller 32. The hydraulic cylinder pushes the piston rod in a linear reciprocating motion, causing the rubber roller 32 to move towards the patterned roller 42 to achieve contact with the patterned roller 42, thereby achieving thermal pressing.

[0034] The second roller unit 40 is located above the first roller unit 30. The second roller unit 40 includes a mounting plate 41, a patterned roller 42, a guide roller 33, and a lifting mechanism 44. The patterned roller 42 is equipped with a heating device to generate heat. The surface of the patterned roller 42 is provided with textures for pressing patterns onto melamine paper. The patterned roller 42 is fixedly mounted in the fixing frame 10 and is pressed against the rubber roller 32. The patterned roller 42 can rotate relative to the fixing frame 10. The face paper is attached to the back paper and is attached between the patterned roller 42 and the rubber roller 32. There are multiple mounting plates 41, which are located at both ends of the patterned roller 42 and fixed in the fixing frame 10, so that the patterned roller 42 is fixed in the fixing frame through the mounting plates 41. The mounting plates 41 are detachably connected to the fixing frame 10 by bolts, so that different patterned rollers 42 can be replaced.

[0035] like Figure 4 As shown, the guide roller 3 43 is mounted on the fixed frame 10 and located between the patterned roller 42 and the bottom paper roller 20. The guide roller 3 43 is positioned at a height higher than the bottom paper roller 20 on the fixed frame 10, and the bottom point of the guide roller 3 43 is positioned at a height higher than the bottom point of the patterned roller 42 on the fixed frame 10. A face paper passes above the guide roller 3 43 and below the patterned roller 42. By setting the guide roller 3 43, the contact area and flatness between the face paper and the patterned roller 42 are improved.

[0036] At least two lifting platforms 44 are respectively installed on both sides of the fixed frame 10 and located below the pattern roller 42. The lifting platforms 44 can be hydraulic cylinders, air cylinders, etc. The lifting end of the lifting platform 44 is connected to the mounting plate 41. When the pattern roller 42 needs to be replaced, the mounting plate 41 is removed from the fixed frame 10, and the lifting platform 44 lifts the pattern roller 42 upward. The pattern roller 42 moves upward to the top of the fixed frame 10, and the auxiliary crane replaces the pattern roller 42.

[0037] The working principle of this utility model is as follows: A melamine paper pressing machine, in use, places the base paper on the base paper roller 20, passes from the bottom of the base paper roller 20 through the top of the guide roller 1 21, then through the bottom of the guide roller 22, and passes between the rubber roller 32 and the patterned roller 42; the face paper passes over the guide roller 33 and then passes between the rubber roller 32 and the patterned roller 42, so that the face paper is on the base paper. The lifting mechanism 31 lifts and drives the rubber roller 32 to approach the patterned roller 42, applying a predetermined pressure to the patterned roller 42. The driving mechanism 33 drives the rubber roller 32 to rotate. At the same time, with the cooperation of the patterned roller 42 and the rubber roller 32, the base paper and the face paper are pressed together, and the embossing operation is performed. Simultaneously, the base paper and the face paper continuously enter between the patterned roller 42 and the rubber roller 32 through the guide roller 2 22 and the guide roller 3 43, realizing continuous pressing and printing operations of the base paper and the face paper, improving production efficiency and reducing labor costs. When it is necessary to replace the smaller patterned roller 42, the mounting plate 41 is removed from the fixed frame 10, the lifting machine 44 lifts the patterned roller 42 upwards, the patterned roller 42 moves to the top of the fixed frame 10, the crane lifts and replaces the patterned roller 42, the new patterned roller 42 is placed in the fixed frame 10, the lifting machine 44 descends so that the patterned roller 42 is tangent to the rubber roller 32, and then the mounting plate 41 is connected to the fixed frame 10 to limit the position of the patterned roller 42.

[0038] 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.
