The bottom surface of the first knurled screw 15 is provided with a cylindrical surface, and the pressure plate 14 is fixedly installed on the cylindrical surface. A guide pin 17 is fixedly installed on the pressure plate 14. In this invention, there are three knurled screws on the pressure strip 12. The middle one is a knurled screw 15 with a cylindrical surface at the bottom. When the conveyor belt passes through, tightening the screw drives the pressure plate 14 below it to apply an upward pressure to the conveyor belt. The left and right knurled screws 13 apply a downward pressure to the conveyor belt during the tightening process. The screw 15 connects to the pressure plate 14 to lift the upper felt pressure strip when changing the felt. The guide pin 17 on the right side serves a guiding function.

[0024] like Figure 3-5 As shown, left and right supports 6 and 32 are installed on the mounting plate 22. A set of tie rods 10 is installed between the left and right supports 6 and 32. A first lead screw 4 and a second lead screw 31 are installed between the tie rods 10. A left guide frame 40 is installed on the first lead screw 4, and a right guide frame 38 is installed on the second lead screw 31.

Upper and lower pressure plates 8 and 5 for pressing the material are provided between the guide plates 20. A power input mechanism is installed at the ends of the first lead screw 4 and the second lead screw 31.

[0025] Preferably, the feed inlets of the upper pressure plate 8 and the lower pressure plate 5 are shaped like the number eight, which facilitates quick capture of the material head and improves accuracy. During installation, the lower pressure plate 5 is installed on the front and rear tie rods through two crescent-shaped grooves, and the upper pressure plate 8 is pressed by the pressure strip 21 and covers the lower pressure plate. The upper and lower pressure plates are of the same width and are consistent with the width of the strip.

[0026] For example, the power input mechanism includes: gears 30 respectively mounted on the same end of the first lead screw 4 and the second lead screw 31, and bearing covers 9 mounted on the other end of each; the gears 30 of the first lead screw 4 and the second lead screw 31 are positioned front and rear, and a pull-out adjustable gear shaft 33 is provided between the two gears 30, with a second handwheel mounted on the output end of the gear shaft 33; the adjustable gear shaft 33 is pulled out by the second handwheel to mesh with the two gears 30 respectively, adjusting the positions of the left and right guide frames 40 and 38. The width between the two gears is infinitely adjustable through the pull-out adjustable gear shaft 33. The three gears are placed inside the gear transmission cover 16, and the adjustable gear shaft 33 is pulled out by the second handwheel to mesh with the gears on different lead screws respectively.

[0027] Furthermore, a guide rail assembly is installed on the ground step mechanism, the mounting plate 22 is mounted on the guide rail assembly via a slider, and a baffle 2 is installed at the end of the guide rail assembly.

[0028] A third lead screw 3 is installed on one side of the support 39. A first handwheel is installed at the end of the third lead screw 3. A first connecting block 29 is fixedly installed on the third lead screw 3 via a first nut 37. The first connecting block 29 is fixedly connected to one side of the bottom of the mounting plate 22. By rotating the first handwheel, the third lead screw 3 is driven, causing the width adjustment mechanism to move left and right on the guide rail assembly. A support block 28 is set at the bottom of the support 39. The support block 28 is fixedly installed on the housing. An adjusting bolt is installed on the support block 28. The adjusting bolt is in contact with the bottom of the support 39. A nut for preventing the adjusting bolt from falling off is provided.

[0029] Guide plates 11 are installed on both sides of the support 39, and the guide plates 11 are fixedly installed on the box body; a gap is directly provided between the guide plates 11 and the box body, and the support 39 is slidably installed in the gap; a fastener for fixing the support 39 to the box body is installed in the middle of the support 39.

[0030] The working process of this invention is as follows: During material feeding, the strip passes through the feed roller 34, then the strip 12 is lifted, and the strip is placed between the upper felt 24 and the lower felt 25. The movable bracket 1 and the strip 12 are fastened, and the strip is pressed by adjusting the three knurled screws. The two knurled screws 13 on the left and right rotate downwards, applying downward pressure to the strip. The knurled screw 15 in the middle has a special structure, which can pull the bottom plate 14 upwards by rotating the knurled screw, so that the strip can obtain pressure in both the upper and lower directions. A guide pin 17 is installed on the lower base of the strip to guide the strip.

[0031] By rotating the first handwheel, the third lead screw 3 is driven to move the width guide device left and right on the guide rail until it is adjusted to the appropriate position. Then, by pulling the second handwheel, the gear shaft 33 is driven to mesh with the gear 30 at the top of the front and rear lead screws. The lead screw rotates, causing the left guide frame 40 and the right guide frame 38 on the front and rear lead screws to move left and right, thereby determining the position of the left and right side guide frames. At the same time, the position of the left and right side guide plates 20 installed on the left and right side guide frames is determined, so that the distance between the two side guide plates is the same as the width of the strip. Install the upper pressure plate 8 and the lower pressure plate 5. The width of the upper and lower pressure plates is the same as that of the strip material, so that the opening faces the direction of the strip material inlet. The lower pressure plate is installed on the front and rear tie rods 10 through two semi-circular holes. The upper pressure plate covers the lower pressure plate. Then, the front and rear pressure strips are installed with knurled screws to apply pressure to the upper and lower pressure plates, thereby pressing the strip material and safely, quickly and efficiently feeding the strip material to the slitting module.

[0032] The present invention has the following advantages: 1. Compact structure, easy to use, and small footprint; 2. Fast adjustment speed improves production efficiency; 3. The adjustment process is accurate, reducing processing errors; 4. High reliability and low maintenance cost; 5. It can be widely used in the field of longitudinal slitting.

[0033] In summary, the present invention has a compact structure, is easy to implement and has low cost. It can achieve rapid and correct guidance of the material before it enters the slitting machine, which helps to improve the efficiency of shearing and the quality of the material, and makes the operation more convenient and user-friendly.

[0034] It will be apparent to those skilled in the art that the above specific examples are merely preferred embodiments of the present invention. Therefore, any improvements or modifications that may be made by those skilled in the art to certain parts of the present invention still embody the principles of the present invention and achieve the objectives of the present invention, and all fall within the scope of protection of the present invention.
