The front and back sides of the threaded sleeve 33 are fixedly connected to a positioning rod 34. The surface of the positioning rod 34 is slidably connected to a transmission frame 35. The top of the transmission frame 35 is rotatably connected to a connecting block 36 via a rotating shaft. The bottom of the inner side of the transmission frame 35 is rotatably connected to a transmission plate 37 via a rotating shaft. The bottom of the transmission plate 37 is rotatably connected to a connecting block 38 via a rotating shaft. The bottom of the connecting block 38 is fixedly connected to a fixed shell 4. Both sides of the surface of the upper forming roller 105 are rotatably connected to both sides of the inner wall of the fixed shell 4 via rotating shafts.

[0019] refer to Figure 1 The frame 2 includes an upright plate 21, which is fixedly connected to both sides of the top of the base 101. A horizontal plate 22 is fixedly connected to the top of the upright plate 21 by screws and screw sleeves. Positioning plates 23 are fixedly connected to the front and rear ends of the bottom of the horizontal plate 22. The top of the connecting block 36 is fixedly connected to both sides of the bottom of the horizontal plate 22. The motor 31 is fixedly connected to the top of the left side of the upright plate 21.

[0020] As a technical optimization of this utility model, by setting up the frame 2, it is easy to assemble and disassemble the frame 2, and at the same time, it provides a stable installation foundation for each component of the spacing control mechanism 3. The positioning plate 23 can play an auxiliary positioning role for the transmission components. The motor 31 is fixed on the upright plate 21, which ensures the stability of power output and further improves the overall reliability of the device during operation.

[0021] refer to Figure 3 Both sides of the surface of the positive and negative threaded rod 32 are fixedly connected with a stabilizing bearing 5, and the outer side of the outer ring of the stabilizing bearing 5 is fixedly connected to the inner side of the cross plate 22.

[0022] As a technical optimization of this utility model, by setting a stable bearing 5, the radial runout of the positive and negative threaded rods 32 during rotation can be effectively reduced, the frictional resistance can be reduced, and the rotation of the positive and negative threaded rods 32 can be made more stable and smooth. This not only extends the service life of the positive and negative threaded rods 32, but also improves the accuracy of the spacing adjustment, ensuring the accuracy of the spacing control between the upper forming pressure roller 105 and the lower forming pressure roller 104.

[0023] refer to Figure 4 A movable plate 6 is fixedly connected to the top of the screw sleeve 33, and a guide block 7 is fixedly connected to the top of the movable plate 6. Guide grooves 8 are provided on both sides of the bottom of the inner wall of the horizontal plate 22, and the guide grooves 8 are slidably connected to the guide block 7.

[0024] As a technical optimization of this utility model, by setting the moving plate 6, the guide block 7 and the guide groove 8, the movement of the threaded sleeve 33 can be guided and limited, preventing the threaded sleeve 33 from deviating or rotating when the threaded rod 32 rotates, ensuring the smoothness of the threaded sleeve 33 moving along the axial direction of the threaded rod 32, thereby improving the operational stability and adjustment accuracy of the spacing control mechanism 3.

[0025] refer to Figure 2 Both sides of the fixed shell 4 are fixedly connected with sliders 9, and the inner side of the upright plate 21 is provided with a sliding groove 10, which is slidably connected to the sliders 9.

[0026] As a technical optimization of this utility model, by setting the slider 9 and the groove 10, the movement direction of the fixed shell 4 can be restricted, so that the fixed shell 4 can drive the upper forming pressure roller 105 to rise and fall smoothly in the vertical direction, avoiding the upper forming pressure roller 105 from tilting during the movement, ensuring that the upper forming pressure roller 105 and the lower forming pressure roller 104 always remain parallel, which is beneficial to improving the forming quality of the bright trim strip.

[0027] refer to Figure 5 A thickening cylinder 11 is fixedly connected to the surface of the lower forming roller 104, and thickening cylinders 2 12 are fixedly connected to both sides of the surface of the upper forming roller 105. The thickening cylinders 11 and 2 12 are thickened sequentially from front to back.

[0028] As a technical optimization of this utility model, by setting thickening cylinder one 11 and thickening cylinder two 12, the thickness of the lower forming pressure roller 104 and the upper forming pressure roller 105 can be increased, and the material can be extruded into other shapes.

[0029] The working principle and usage process of this utility model are as follows: When in use, the motor 31 of the spacing control mechanism 3 is started. The motor 31 drives the positive and negative threaded rods 32 to rotate. Because the threads on both sides of the positive and negative threaded rods 32 are in opposite directions, the threaded sleeves 33 on their surfaces move relative to or towards each other along the axial direction. At this time, the guide block 7 on the top moving plate 6 of the threaded sleeve 33 slides along the guide groove 8 on the inner wall of the horizontal plate 22, which guides and limits the threaded sleeve 33, ensuring its smooth movement. When the threaded sleeve 33 moves, the positioning rods 34 on its front and back sides slide within the transmission frame 35, causing the transmission frame 35 to rotate around the pivot connected to the connecting block 1 36. The rotation of the transmission frame 35 causes the transmission plate 37 at the bottom inner side to move. The transmission plate 37 pushes the connecting block 2 38 and the bottom fixed shell 4 to rise and fall. The sliders 9 on both sides of the fixed shell 4 slide along the groove 1 on the inner side of the vertical plate 21. 0 sliding ensures that the fixed shell 4 drives the upper forming roller 105 to rise and fall vertically and smoothly. Adjust the distance between the upper forming roller 105 and the lower forming roller 104, and then convey the material to be processed through the roller 103 at the front end of the connecting frame 102. The rotation of the roller 103 provides forward power for the material, allowing it to smoothly enter the forming area between the lower forming roller 104 and the upper forming roller 105. After the material enters between the lower forming roller 104 and the upper forming roller 105, the thickened cylinder 11 on the surface of the lower forming roller 104 and the thickened cylinder 22 on the surface of the upper forming roller 105 extrude the material. Under extrusion, the material is gradually formed into a bright decorative strip of the required specifications. Throughout the process, the upright plate 21, the horizontal plate 22 and the positioning plate 23 of the frame 2 provide stable support for each component, ensuring that the forming process is stable and reliable.

[0030] In summary, this forming device for producing bright decorative strips, by setting up a forming device 1, a frame 2, and a spacing control mechanism 3, utilizes a motor 31 to drive the positive and negative threaded rods 32 to rotate, thereby driving the screw sleeve 33, positioning rod 34, transmission frame 35, and transmission plate 37 to move up and down the upper forming pressure roller 105, thus automatically adjusting the spacing between the upper forming pressure roller 105 and the lower forming pressure roller 104. This structure eliminates the need for manual adjustment, is easy to operate, effectively improves adjustment efficiency and accuracy, ensures the consistency of the bright decorative strip forming dimensions, and has a stable and reliable overall transmission structure, adapting to the production needs of bright decorative strips of different specifications.
