Technical Field
[0001] This utility model relates to the field of cutting devices, and more particularly to a cutting device for melamine-impregnated paper. Background Technology
[0002] Melamine-impregnated paper, also known as melamine-impregnated adhesive paper or "melamine" paper, is a type of paper made by impregnating plain paper or printed decorative paper with amino resin and drying it to a certain degree. It has a certain resin content and volatile content. It can be glued together with each other or glued to artificial board substrates through hot pressing. During the processing of melamine-impregnated paper, a cutting device is needed to cut the melamine-impregnated paper into certain specifications.
[0003] In existing technologies, conventional melamine paper cutting devices feed melamine paper by rotating a feeding roller, and then cut it by pressing down with a cutting blade. However, during the cutting process, the cutting blade squeezes and pulls the melamine paper, easily causing it to tear and reducing the quality of the cut. Furthermore, the feeding of the melamine paper is driven by the friction of the rotating feeding roller. Due to the waterproof nature of melamine paper, the friction between the roller surface and the paper is low, making it prone to slippage and displacement during transport. This reduces the accuracy of the melamine paper cutting, further lowering the quality of the finished product. Therefore, a melamine-impregnated paper cutting device is proposed to address these problems. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a cutting device for melamine-impregnated paper, which aims to improve the problem in the prior art that "the friction between the surface of the feeding roller and the melamine paper is small, which easily causes the melamine paper to slip and shift during the conveying process, thus leading to a decrease in the accuracy of cutting the melamine paper".
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cutting device for melamine-impregnated paper, comprising a base, a cutting mechanism at the top of the base, a pressing mechanism at the top of the base, a column fixedly connected to the top of the base, a fixing plate fixedly connected to the top of the column, a pressure plate slidably connected to the outer wall of the column, a control rod fixedly connected to the top of the pressure plate, the control rod penetrating and slidably connected to the inner wall of the fixing plate, a spring sleeved on the surface of the control rod, a fixing block fixedly connected to the top of the base, a connecting rod hinged to the surface of the fixing block, a connecting rod two hinged to the end of the connecting rod one away from the fixing block, a slider hinged to the end of the connecting rod two away from the connecting rod one, the slider slidably connected to the inner wall of the base, the top of the slider elastically connected to the inner wall of the base via the spring two, the connecting rod one hinged to the connecting rod two via a pin, and grooves provided on the front and rear sides of the pressure plate.
[0006] As a further description of the above technical solution:
[0007] The bottom of the top fixing plate of the first spring is fixedly connected, and the bottom of the first spring is fixedly connected to the top of the pressure plate.
[0008] As a further description of the above technical solution:
[0009] The outer wall of the pin contacts the inner wall of the groove.
[0010] As a further description of the above technical solution:
[0011] The lengths of the first connecting rod and the second connecting rod are equal.
[0012] As a further description of the above technical solution:
[0013] The cutting mechanism includes a support column, which is fixedly connected to the top of the base, and a support plate is fixedly connected to the top of the support column.
[0014] As a further description of the above technical solution:
[0015] The cutting mechanism also includes a hydraulic cylinder, which is fixedly connected to the top of the support plate, and a pressure shell is fixedly connected to the bottom of the output shaft of the hydraulic cylinder.
[0016] As a further description of the above technical solution:
[0017] The cutting mechanism also includes a cutting blade, which is fixedly connected to the bottom of the pressure shell.
[0018] As a further description of the above technical solution:
[0019] The top of the base is fixedly connected to multiple support legs.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, by pulling the control lever upward, the pressure plate is displaced upward against the elastic force of the first spring. Then, the melamine paper is placed at the bottom of the pressure plate on the top of the base. Releasing the control lever causes the pressure plate to press the melamine paper downward under the elastic force of the first spring, increasing the friction between the melamine paper and the top of the base. This ensures that the melamine paper will not shift during the cutting process, thereby improving the cutting accuracy and the quality of the finished product.
[0022] 2. In this utility model, when the pressure plate moves down, the elastic force of the second spring acts on the slider, pushing the slider to slide downward, causing the first and second connecting rods to rotate around their respective hinge points. The rotation of the second connecting rod causes the pin to move in the groove, thereby causing the pressure plate to slide downward, further increasing the pressure on the melamine paper and preventing the melamine paper from being torn during the cutting process, which would reduce the quality of the paper cutting.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figure 1 , Figure 2 One embodiment of this utility model is a melamine-impregnated paper cutting device, which includes a base 1. The top of the base 1 is fixedly connected with a plurality of support legs 19 that support the overall structure. The top of the base 1 is provided with a cutting mechanism 12 and a pressing mechanism 10. The number of pressing mechanisms 10 is set to two sets, and the two sets of pressing mechanisms 10 are respectively arranged on the left and right sides of the cutting mechanism 12.
[0030] Reference Figure 1 - Figure 3 The pressing mechanism 10 includes a vertically arranged column 101, which is fixedly connected to the top of the base 1. A fixing plate 102 is fixedly connected to the top of the column 101. A pressure plate 103 is slidably connected to the outer wall of the column 101. The column 101 can guide the displacement direction of the pressure plate 103, so that the pressure plate 103 can make more precise linear movements. The pressure plate 103 stably presses the melamine paper onto the top of the base 1, improving the cutting accuracy and quality. A control rod 104 is fixedly connected to the top of the pressure plate 103. The control rod 104 passes through and is slidably connected to the inner wall of the fixing plate 102. A spring 105 is sleeved on the surface of the control rod 104. The spring 105 applies a downward elastic force to the pressure plate 103.
[0031] Reference Figure 2 , Figure 3 The bottom of the top fixing plate 102 of the spring 105 is fixedly connected, the bottom of the spring 105 is fixedly connected to the top of the pressure plate 103, the top of the base 1 is fixedly connected to the fixing block 106, the surface of the fixing block 106 is hinged to the connecting rod 107, the connecting rod 107 and the connecting rod 2 108 are both set to an inclined state, the end of the connecting rod 107 away from the fixing block 106 is hinged to the connecting rod 2 108, the length of the connecting rod 107 and the length of the connecting rod 2 108 are equal.
[0032] Reference Figure 2 , Figure 3 A slider 111 with a rectangular cross-section is hinged to the end of the connecting rod 108 away from the connecting rod 107. The slider 111 is slidably connected to the inner wall of the base 1. The slider 111 slides up and down. The top of the slider 111 is elastically connected to the inner wall of the base 1 through the spring 112. The spring 112 applies a downward elastic force to the slider 111. The connecting rod 107 is hinged to the connecting rod 108 through the pin 109. The pressure plate 103 has grooves 110 on both the front and rear sides. The outer wall of the pin 109 contacts the inner wall of the groove 110, so that the pressure plate 103 can be finely adjusted in position while maintaining a pressed state to adapt to melamine paper of different thicknesses.
[0033] Reference Figure 1 , Figure 2 The cutting mechanism 12 includes a vertically arranged support column 121, which is fixedly connected to the top of the base 1. A support plate 122 is fixedly connected to the top of the support column 121. The cutting mechanism 12 also includes a hydraulic cylinder 123. When the hydraulic cylinder 123 is working, it drives the cutting blade 125 at the bottom of the pressure shell 124 to move up and down. The hydraulic cylinder 123 is fixedly connected to the top of the support plate 122. The bottom of the output shaft of the hydraulic cylinder 123 is fixedly connected to the pressure shell 124. The cutting mechanism 12 also includes a cutting blade 125 for cutting melamine paper, which is fixedly connected to the bottom of the pressure shell 124.
[0034] Working principle: In use, pull the control lever 104 upwards, causing the pressure plate 103 to move upwards against the elastic force of spring 105. Then, place the melamine paper at the bottom of the pressure plate 103 on the top of the base 1. Release the control lever 104, causing the pressure plate 103 to press the melamine paper downwards under the elastic force of spring 105, completing the initial fixation. When the pressure plate 103 moves downwards, the elastic force of spring 112 acts on the slider 111, pushing the slider 111 to slide downwards. The movement of the slider 111 will drive the connecting rod 107 and connecting rod 108. 08 rotates around its respective hinge point. Since the outer wall of the pin 109 is in contact with the inner wall of the groove 110 on both sides of the pressure plate 103, the rotation of the connecting rod 108 will cause the pin 109 to move in the groove 110, thereby driving the pressure plate 103 to overcome the elastic force of the spring 105 and slide down along the column 101, further increasing the pressing force on the melamine paper, thereby increasing the friction between the melamine paper and the top of the base 1, ensuring that the melamine paper will not be displaced during the cutting process, thereby improving the cutting accuracy and the quality of the finished product.
[0035] After the melamine paper is fixed, the hydraulic cylinder 123 is started. The output shaft of the hydraulic cylinder 123 drives the cutting blade 125 at the bottom of the pressure shell 124 to move downward, and automatically cuts the melamine paper. The pressure shell 124 can press the melamine paper, reducing manual operation steps and thus improving work efficiency. After the cutting is completed, by pulling the control rod 104 upward, the pressure plate 103 overcomes the elastic force of the spring 105 and slides upward along the column 101, thereby releasing the pressure on the melamine paper, and the cut melamine paper can be taken out.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
