Abstract

The invention discloses an elastic extrusion tensioning mechanism of a special paper coating machine. The upper ends of two guide rods are connected by a horizontal plate, and the horizontal plate is located on the upper side of the connecting rod. The middle part of the upper end of the connecting rod is A guide cylinder with an upward opening is provided, and a spring is provided at the bottom of the inner cavity of the guide cylinder. A threaded rod is inserted into the position corresponding to the upper end of the horizontal plate and the guide cylinder, and the lower end of the thread rod goes deep into the guide cylinder. The lower end of the threaded rod is against the spring. The process is: S1 installation, S2 debugging efforts, S3 experiment and S4 re-debugging. The motor drives the driving roller to rotate, and the linear speed of the driving roller is greater than the transmission speed of the special paper, so that there will be slippage between the special paper and the stretching and tensioning effect. By rotating the rotating rod, the spring below is squeezed. The extrusion force of the driven roller can be adjusted to prevent excessive friction. At the same time, the flannelette layer on the top protects the paper from damage and ensures the transmission quality of special paper.

Example Embodiment

[0019] In the following, with reference to the drawings, through the description of the embodiments, the specific implementation of the present invention such as the shape and structure of the various components involved, the mutual position and connection relationship between the various parts, the function and working principle of each part, and the manufacturing process And the operation and use method, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical scheme of the present invention.
[0020] An elastic squeeze-type tensioning mechanism for a special paper coating machine includes an active roller 1. The center of the left and right ends of the active roller 1 is provided with a lower rotating shaft 2, and the active roller 1 is located under the working table 3 of the coating machine. On the side, the workbench 3 is provided with a receiving groove corresponding to the upper end of the active roller 1, and the upper end of the active roller 1 extends out of the receiving groove, and the left and right ends of the lower shaft 2 are rotatably connected with a support plate 4, and two support plates 4 Fixed at the lower end of the workbench 3, one of the lower rotating shafts 2 passes through the support plate 4 and is connected with a motor 5, the motor 5 is fixed on the corresponding support plate 4, the upper side of the workbench 3 is provided with a driven roller 66, and the driven The drum 6 is located directly above the driving drum 1, and the middle of the left and right ends of the driven drum 6 are rotatably connected with upper rotating shafts, and the two upper rotating shafts are provided with upward sliding cylinders 7 on the back end surfaces.
[0021] The sliding cylinder 7 is inserted with a guide rod 8, the lower end of the guide rod 8 is fixed on the worktable 3, the upper ends of the two sliding cylinders 7 are connected by a connecting rod 9, and the sliding cylinder 7 and the worktable 3 are connected by a support spring 15 Connected, and the support spring 15 is sleeved on the corresponding guide rod 8, to balance the weight of the driven roller 6, prevent the starting point of the extrusion force from being too large, and expand the adjustment range, and the connecting rod 9 is located on the upper side of the driven roller 6 , The upper ends of the two guide rods 8 are connected by a horizontal plate 10, and the horizontal plate 10 is located on the upper side of the connecting rod 9. The upper middle of the connecting rod 9 is provided with a guide tube 11 with an upward opening, and the inner cavity of the guide tube 11 A spring 12 is provided at the bottom. A threaded rod 13 is inserted into the position of the upper end of the horizontal plate 10 corresponding to the guide tube 11, and the lower end of the threaded rod 13 penetrates into the guide tube 11, and the lower end of the threaded rod 13 abuts on the spring 12, The upper end of the threaded rod 13 is connected with a rotating rod 16 to facilitate the rotation of the threaded rod 13. An elastic rubber layer is sleeved on the rotating rod 16 to prevent hand grinding. The outer ends of the driving drum 1 and the driven drum 6 are both provided with a flannel layer 14 in the circumferential direction. , To prevent damage to special paper, but also to prevent excessive friction and scratches on special paper.
[0022] The process is:
[0023] S1: Installation: Pass the special paper between the driving roller 1 and the driven roller 6;
[0024] S2: Debugging intensity: Rotate the rotating rod 16 according to the thickness of the special paper to make the driven roller 6 squeeze the special paper;
[0025] S3: Experiment: Start the experiment and observe the friction situation;
[0026] S4: Re-commissioning: According to the experimental result of step S3, turn the rotating rod 16 to a suitable position.
[0027] The motor drives the active roller 1 to rotate, and the linear speed of the active roller 1 is greater than the transmission speed of the special paper. This will cause slippage with the special paper, which can stretch and tension the lower part by rotating the rotating rod 16. The spring 12 can adjust the squeezing force of the driven roller 6 to prevent excessive friction. At the same time, the upper flannel layer 14 protects the paper from damage and ensures the transmission quality of special paper.
[0028] The present invention has been exemplarily described above in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited by the above methods, as long as the method concept and technical solution of the present invention are used for various insubstantial improvements or without improvements. Application of the concept and technical scheme of the present invention to other occasions directly falls within the protection scope of the present invention. The protection scope of the present invention should be subject to the protection scope defined by the claims.
