In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: the embossing plate can be quickly fixed to the three-sided pressing block by inserting the embossing plate into the installation groove and then turning the buckle, so that the staff can disassemble and replace the embossing plate conveniently. During use, the traditional embossing device is prone to wrinkles when the conveyor belt transports the paper product, which causes the embossed paper product to be wrinkled and the pattern is uneven, thereby affecting the quality of the embossing of the paper product. For this reason, it is necessary to design a new technical solution to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide an embossing device for paper product processing to solve the technical problem that the current embossing device is prone to wrinkles when conveying paper products on a conveyor belt, which causes wrinkles and uneven patterns on the embossed paper products, thereby affecting the quality of the embossed paper products.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing an embossing device for paper product processing, including a U-shaped table, the inner cavity of the U-shaped table is equipped with a belt conveyor, the top of the U-shaped table is equipped with a frame, the top of the frame is equipped with a driving mechanism, and the inner side of the frame is equipped with an embossing mechanism; electric telescopic rods are installed on both sides of the top of the inner cavity of the frame, the driving motors of the two electric telescopic rods are fixedly connected with adjustment plates, the outer ends of the two adjustment plates are fixedly connected with connecting blocks on both sides, the opposite ends of the two groups of connecting blocks are rotatably connected with connecting rods through connecting shafts, rollers are rotatably provided between the two groups of connecting rods through connecting shafts, and a first spring is fixedly connected between the two adjustment plates and the four connecting rods.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Embodiment 1: An embossing device for paper product processing, see Figures 1 to 4, including a U-shaped table 1, a belt conveyor 2 is installed in the inner cavity of the U-shaped table 1, a frame 3 is installed on the top of the U-shaped table 1, a driving mechanism is installed on the top of the frame 3, the driving mechanism includes mounting blocks 4 installed on both sides of the top of the frame 3, a rotating shaft 41 rotatably connected between the two mounting blocks 4 and a cam 42 fixedly connected to the middle of the rotating shaft 41, a driving motor 43 is installed on the outer side of one of the mounting blocks 4, and the driving end of the driving motor 43 is fixedly connected to the rotating shaft 41, and an embossing mechanism is installed on the inner side of the frame 3, and the embossing mechanism includes a sliding penetrating A push rod 56 at the top of the frame 3, a pressure plate 55 connected to the top of the push rod 56, an inverted U-shaped frame 5 installed at the bottom of the push rod 56, and an embossing roller 51 rotatably connected to the inner side of the inverted U-shaped frame 5, a second spring 57 is sleeved on the outer side of the push rod 56 between the frame 3 and the inverted U-shaped frame 5, and the two ends of the second spring 57 are respectively connected to the frame 3 and the inverted U-shaped frame 5; electric telescopic rods 6 are installed on both sides of the top of the inner cavity of the frame 3, and the driving motors 43 of the two electric telescopic rods 6 are fixedly connected to the adjustment plates 61, and the outer ends of the two adjustment plates 61 are A connecting block 62 is fixedly connected, and the opposite ends of the two groups of connecting blocks 62 are rotatably connected to a connecting rod 63 through a connecting shaft. A roller 64 is rotatably connected between the two groups of connecting rods 63 through a connecting shaft. A first spring 65 is fixedly connected between the two adjustment plates 61 and the four connecting rods 63. When the paper product to be embossed can be conveyed to the bottom of the embossing roller 51 through the belt conveyor 2, the roller 64 on the left side contacts the paper product to smooth the paper product and remove wrinkles, and then the cam 42 is driven to rotate by starting the driving motor 43. Thereby, the pressing plate 55 is pushed to move downward, thereby pushing the embossing roller 51 to contact the paper product for embossing. The embossing roller 51 can be automatically reset in cooperation with the second spring 57, so that continuous paper products can be embossed. Before embossing, the electric telescopic rod 6 is started to push the adjusting plate 61 to move downward. Since there is a certain friction between the roller 64 and the paper product, the rollers 64 on both sides of the paper product tighten the parts of the paper product that need to be embossed, thereby avoiding wrinkles on the paper product before embossing, thereby improving the quality of embossing of the paper product.

[0022] For details, see Figure 2 Four embossing plates 54 with different patterns are installed on the outer side of the embossing roller 51, and a bolt 52 is rotatably penetrated at one end of the inverted U-shaped frame 5. Four threaded holes 53 are provided at one end of the embossing roller 51 close to the bolt 52. By screwing the bolt 52 to disengage the threaded hole 53, the embossing roller 51 can be rotated to make the embossing plates 54 with different patterns correspond to the paper products. When the required embossing plate 54 is rotated, the bolt 52 is screwed and threadedly connected with the threaded hole 53, which makes it easy to limit the embossing plate 54, thereby facilitating the rapid replacement of different embossing plates 54 and avoiding wasting time and affecting production efficiency when replacing the embossing plate 54.

[0023] For further information, see Figure 1A limiting groove 7 is provided at the opposite end of the two mounting blocks 4, and a limiting block 71 is slidably connected in the two limiting grooves 7, and the two limiting blocks 71 are fixedly connected to the pressing plate 55. The limiting blocks 71 are guided to move in the limiting grooves 7, thereby improving the stability of the up and down movement of the pressing plate 55, thereby improving the stability of the contact between the embossing plate 54 and the paper product, and further improving the quality of the embossing of the paper product.

[0024] It is worth noting that see Figure 4 The inner cavity of the U-shaped table 1 is fixedly connected with a support plate 8, and the belt above the belt conveyor 2 is overlapped on the support plate 8. The support plate 8 can support the belt on the belt conveyor 2 to avoid the belt from breaking during embossing.

[0025] It is worth noting that see Figure 2 The four threaded holes 53 correspond to the middle parts of the four embossing plates 54 respectively, and are used to ensure that the replaced embossing plates 54 are placed horizontally and parallel to the paper products on the belt conveyor 2, thereby preventing the embossing plates 54 from tilting and affecting the quality of the embossing of the paper products.

[0026] In addition, the components designed in the present invention are all universal standard parts or components known to technical personnel in the field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. They can be fully implemented by technical personnel in the field, and there is no need to elaborate.
