The following embodiments are used to illustrate this utility model.

[0028] Cardboard forming and crushing equipment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including

[0029] The base plate 10 has a stabilizing bracket 12 fixed at each of the four corners of its top surface, and two stabilizing seats 11 symmetrically fixed at the center of its top surface. A conveyor belt 14 is installed between the four stabilizing brackets 12, and a thickness adjustment structure and a disinfection structure are installed between the two stabilizing seats 11. Two rolling rollers 23 are installed between the two stabilizing seats 11.

[0030] The thickness adjustment structure includes a fixed bevel gear 25, a spline 26, a sliding bevel gear 27, and a driven bevel gear 31. The driven bevel gear 31 is fixedly connected to one end of the rolling roller 23. The fixed bevel gear 25 is rotatably mounted on one side of the stabilizing seat 11. The spline 26 is fixedly mounted on the fixed bevel gear 25, and the sliding bevel gear 27 is sleeved on the spline 26.

[0031] Specifically, the base plate 10 serves as the installation foundation and load-bearing platform for the entire equipment. The stabilizing bracket 12 is fixed to the base plate 10 by welding and is used to support and position both ends of the conveyor belt 14 to ensure the smooth operation of the conveyor belt 14. The conveyor belt 14 is made of food-grade or medical-grade non-toxic material and is used to transport cardboard before and after forming and pressing, realizing automated or semi-automated production, reducing manual contact and lowering the risk of contamination. A thickness adjustment structure and a disinfection structure are installed between the two stabilizing brackets 11, and two pressing rollers 23 are installed between the two stabilizing brackets 11. The two pressing rollers 23 are arranged vertically to form the cardboard pressing and forming working area.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, the disinfection structure includes a disinfection tank 13, a conveying pipe 18, a spray pipe 28, an ultraviolet lamp 29, and a heating pipe 30. The disinfection tank 13 is fixedly installed on the top surface of the base plate 10. The conveying pipe 18 connects the disinfection tank 13 and the spray pipe 28. There are two spray pipes 28, two ultraviolet lamps 29, and two heating pipes 30. The two ultraviolet lamps 29 and the two heating pipes 30 are movably arranged near the rolling roller 23.

[0033] like Figure 3 , Figure 4 and Figure 5 As shown, a delivery pump 22 is fixedly installed on the top surface of the disinfection tank 13. The input end of the delivery pipe 18 is connected to the disinfection tank 13 through the delivery pump 22. The delivery pipe 18 is a C-shaped pipe. Multiple atomizing nozzles are arrayed on the spray pipe 28. The output ends of the two ends of the delivery pipe 18 are connected to the two spray pipes 28 respectively. The output end of the spray pipe 28 is close to the curved surface of the rolling roller 23.

[0034] like Figure 2 and Figure 4 As shown, two mounting slots 21 are symmetrically opened on the inner side of the stabilizing base 11. The ultraviolet lamp 29 and the heating tube 30 are respectively installed in the two mounting slots 21. The ultraviolet lamp 29 and the heating tube 30 are respectively connected to external power switches.

[0035] Specifically, the disinfection structure is the key to meeting the medical sterility requirements of this utility model. The disinfection tank 13 is used to store medical disinfectant, and the delivery pipe 18 provides the delivery power. The delivery pipe 18 is a C-shaped flexible tube. The connection between the delivery pipe 18 and the upper spray pipe 28 bypasses the top of the stabilizing base 11, and the connection between the delivery pipe 18 and the lower spray pipe 28 passes through the stabilizing base 11 to avoid interference with moving parts. Multiple atomizing nozzles are arrayed on the spray pipe 28 to ensure that the disinfectant can be sprayed evenly and finely. The atomizing nozzles of the spray pipe 28 are close to the curved surface of the rolling roller 23. The two spray pipes 28 are respectively set to wrap around part of the outer periphery of the rolling roller 23, so that the rolling roller 23 can be fully sprayed with disinfectant before, during or after work. Two ultraviolet lamps 29 and heating tubes 30 are movably arranged near the rolling roller 23. The position of the mounting groove 21 allows the ultraviolet lamps 29 to irradiate and sterilize the surface of the cardboard after being rolled by the rolling roller 23, and also assists in disinfecting the surface of the rolling roller. The heating tube 30 is used to quickly dry the surface of the roller 23 after spraying and disinfection, to prevent moisture residue from causing the cardboard to become damp or breed bacteria. It can also slightly heat the cardboard to help with forming or remove residual moisture. The ultraviolet lamp 29 and the heating tube 30 are respectively connected to external power switches so that they can be independently controlled to turn on and off according to actual work needs.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, each of the two stabilizing seats 11 has a positioning groove 20, and the same feeding plate 15 is engaged between the two positioning grooves 20. An arched support frame 17 is slidably provided on the top of the two stabilizing seats 11, and one of the rolling rollers 23 is rotatably arranged inside the support frame 17.

[0037] like Figure 2 and Figure 3As shown, a mounting box 16 is fixedly provided on one side of one of the stabilizing bases 11. A motor 24 is fixedly provided on the bottom surface of the mounting box 16. The output end of the motor 24 is connected to the bottom end of the spline 26. The fixed bevel gear 25 rotates on the bottom surface inside the mounting box 16. The fixed bevel gear 25 and the sliding bevel gear 27 respectively mesh with a driven bevel gear 31.

[0038] like Figure 3 As shown, a slide rail 19 is provided inside the stabilizing seat 11. The rolling roller 23 inside the support frame 17 is slidably disposed between the two slide rails 19. A shaft is provided inside the rolling roller 23. One end of the shaft is fixedly connected to the driven bevel gear 31. The shaft slides between the two slide rails 19. Another rolling roller 23 is rotatably disposed between the two stabilizing seats 11. A handle threaded rod is threaded inside one of the stabilizing seats 11. The bottom end of the handle threaded rod is rotatably connected to the rolling roller 23 on the upper side.

[0039] The specific implementation method is as follows: The thickness adjustment structure is the core of this utility model to meet the needs of medical fixed cardboard of different thicknesses. Each crushing roller 23 is fixedly connected to a driven bevel gear 31 at the same end. The spline 26 is rotatably mounted on the mounting box 16 through the bearing seat. The fixed bevel gear 25 rotates in the mounting box 16 through the spline 26. The spline 26 and the fixed bevel gear 25 are coaxial. The inner hole of the sliding bevel gear 27 is provided with a keyway that cooperates with the spline 26, so that the sliding bevel gear 27 can slide along the axial direction of the spline 26 and rotate synchronously with the spline 26. The fixed bevel gear 25 meshes with the driven bevel gear 31 at the end of the lower crushing roller 23, while the sliding bevel gear 27 meshes with the driven bevel gear 31 at the end of the corresponding lower crushing roller 23. The feeding plate 15 is used to guide the cardboard to be processed to accurately enter between the two crushing rollers 23, and the feeding plate 15 of different thicknesses or materials can be replaced as needed. The two ends of the support frame 17 can be The upper pressing roller 23 is slidably embedded between two stable seats 11. The two ends of the roller 23 shaft extend out of the roller body through the bearings in the support frame 17. When it is necessary to adjust the gap between the two pressing rollers 23, the shaft is driven by turning the threaded rod of the handle. The shaft drives the support frame 17 to slide along the top of the stable seat 11. At the same time, the shaft of the upper pressing roller 23 slides up and down in the slide rail 19. During this process, the driven bevel gear 31 at the right end of the shaft will drive the sliding bevel gear 27 meshing with it to slide axially along the spline 26. Due to the action of the spline 26, the sliding bevel gear 27 always rotates synchronously with the spline 26, thereby ensuring that the power of the motor 24 can be transmitted to the driven bevel gear 31 of the upper pressing roller through the spline 26 and the sliding bevel gear 27 at different thickness adjustment positions, and at the same time transmitted to the driven bevel gear 31 of the lower pressing roller through the fixed bevel gear 25, ensuring that the two pressing rollers 23 always rotate in opposite directions to complete the pressing of the cardboard.
