The adjustable spacing between adjacent guide rollers can limit and guide the conveying of corrugated cardboard in different widths, avoiding the situation where the corrugated cardboard deviates during the slitting process and the slitting quality of the corrugated cardboard is reduced. It is highly practical. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 6The adjustable-width longitudinal cutting mechanism of this utility model mainly includes a movable plate 5. A second through hole 30 is provided at the center of the end wall of the movable plate 5. A slide rod 6 is installed in the second through hole 30. Both ends of the slide rod 6 pass through the third through hole 38 on the outer wall of the side plate 1 and are connected to the fastening plate 17. The side plate 1 is installed on both sides of the lower surface of the top plate 40. The lower surface of the movable plate 5 is connected to the third connecting plate 11 through the first connecting rod 10. A hydraulic cylinder 9 is installed at the center of the upper surface of the third connecting plate 11. A hydraulic telescopic rod 13 is installed at the bottom end of the hydraulic cylinder 9. The bottom end of the hydraulic telescopic rod 13 passes through the surface of the third connecting plate 11 and is connected to the fourth connecting plate 12. The lower surface of the fourth connecting plate 12 is connected to the fifth connecting plate 12 through the second connecting rod 15. The fifth connecting plate 16 is connected to the first connecting plate 7. A geared motor 14 is installed on one side of the upper surface of the fifth connecting plate 16, and an eighth connecting plate 34 is installed on one side of the lower surface of the fifth connecting plate 16. A third connecting shaft 37 is installed in the bearing on the outer wall of the eighth connecting plate 34, and a cutting blade 26 is provided on the outer wall of the other end of the third connecting shaft 37. A second connecting plate 8 is installed on the upper surface of the moving plate 5. The second connecting plate 8 is fixedly connected to the first connecting plate 7 by fastening bolts. The other end of the first connecting rod 10 passes through the strip-shaped slot 27 at the center of the surface of the scale plate 2 and is connected to the iron block 29. An electromagnet plate 28 is provided at the top of the iron block 29 and is installed on the lower surface of the top plate 40. A scale pointer 4 is provided below the front end face of the first connecting plate 7. Support plates 18 are installed on both sides of the lower surface of the top plate 40. An electric push rod 22 is installed on the lower part of one outer wall of the support plate 18. The other end of the electric push rod 22 passes through the outer wall of the support plate 18 and is connected to the seventh connecting plate 23. A sixth connecting plate 21 is installed on the upper and lower parts of the other outer wall of the seventh connecting plate 23. Guide rollers 24 are set between each pair of adjacent sixth connecting plates 21. When the operator needs to adjust the distance between adjacent cutting blades 26, the operator de-energizes the electromagnet plate 28, so that the electromagnet plate 28 loses its magnetism and the iron block 29 is no longer magnetically connected to the electromagnet plate 28. The operator then moves the moving plate 5, which indirectly causes the cutting blades 26 and the scale pointer 4 to move. The operator can adjust the spacing between adjacent cutting blades 26 according to the scale mark 3 pointed to by the scale pointer 4. This utility model makes it easy for the operator to adjust the spacing between adjacent cutting blades 26, and can cut corrugated cardboard into the required width according to actual production needs. The start of the electric push rod 22 will indirectly drive the guide roller 24 to move in the X-axis direction. The movement of the guide roller 24 in the X-axis direction can adjust the spacing between adjacent guide rollers 24. The adjustable spacing between adjacent guide rollers 24 can limit and guide the corrugated cardboard in different width conveying states, and avoid the corrugated cardboard in the conveying state from deviating during the cutting process, which would lead to a decrease in the cutting quality of the corrugated cardboard.

[0028] The outer wall of the slide rod 6 is gap-connected with the walls of the second through hole 30 and the third through hole 38. This gap connection allows for limiting and guiding the movement of the movable plate 5. External threads are provided on the outer walls of both ends of the slide rod 6. A threaded hole 39 is provided on the outer wall of the fastening plate 17. The external threads on the outer wall of the slide rod 6 and the threaded hole 39 on the fastening plate 17 are threadedly engaged. This threaded engagement allows workers to assemble and disassemble the fastening plate 17, slide rod 6, and movable plate 5. A first bevel gear 31 is mounted on the output shaft of the reduction motor 14. The first bevel gear 31 meshes with a second bevel gear 32. The second bevel gear 32 is mounted on the top of the second connecting shaft 33. The bottom end of the second connecting shaft 33 passes through a bearing on one side of the surface of the fifth connecting plate 16. The third bevel gear 35 is connected to the fourth bevel gear 36, which meshes with the third bevel gear 36. The fourth bevel gear 36 is installed at one end of the third connecting shaft 37. The outer wall of the first connecting plate 7 and the wall of the slot 27 are connected by a gap. Because the outer wall of the first connecting plate 7 and the wall of the slot 27 are connected by a gap, the movement of the first connecting plate 7 can be limited and guided. The scale plate 2 is installed between adjacent side plates 1. The front end face of the scale plate 2 is provided with scale marks 3. The center positions of the end walls of both ends of the guide roller 24 are equipped with the first connecting shaft 20. The other end of the first connecting shaft 20 is installed in the bearing on the surface of the sixth connecting plate 21. The upper part of the outer wall of the support plate 18 is provided with a first through hole 19, and the horizontal center line of the first through hole 19 coincides with the horizontal center line of the slide rod 6. The inner diameter of the first through hole 19 is larger than the outer diameter of the slide rod 6. The bottom end of the support plate 18 is equipped with a fixing plate 25.
