DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In one embodiment, see Figure 1-Figure 12 , a cutting device for decorative paper production, comprising a supporting base plate 1, a slitting mechanism 2 and a winding mechanism 3; The slitting mechanism 2 includes an L-shaped support frame 12 fixedly connected to the end of the support base plate 1, the L-shaped support frame 12 is fixed to the front and rear ends of the left side of the support base plate 1, and in order to reduce the volume of the entire support base plate 1, the L-shaped support frame 12 is tilted to the upper left, and the short side of the L-shaped support frame 12 is located on the upper left side. A plurality of cutting wheels 7 are arranged between the front and rear L-shaped support frames 12, and the cutting wheels 7 can be used for slitting large-sized paper rolls, and the spacing of the cutting wheels 7 can be freely adjusted, so that large-sized paper rolls can be cut into small paper rolls of different sizes; The winding mechanism 3 includes a vertical rod 17 fixedly connected to the supporting base plate 1, the vertical rod 17 is vertically arranged and located on the right side of the L-shaped support frame 12, and a hanging plate 18 inclined to the lower right is fixedly connected to the upper end of the vertical rod 17, and a slide groove 24 is arranged in the middle of the hanging plate 18, and the slide groove 24 is slidably connected to the slider 25, so that the slider 25 can slide toward the lower right along the hanging plate 18, and the middle part of the slider 25 is rotatably connected to the first rotating rod 26 arranged in the front and rear directions, and the middle part of the first rotating rod 26 is rotatably connected to the end of the deflection plate 20, and the plane where the deflection plate 20 and the hanging plate 18 are located is parallel, and the deflection plate 20 is away from the first rotating rod One end of the rod 26 is rotatably connected to a second rotating rod 27 arranged in a front-to-back direction, and a driven roller 21 arranged in a front-to-back direction is detachably connected between the two front and rear first rotating rods 26 and between the two front and rear second rotating rods 27. The outer part of the driven roller 21 is provided with a small paper roll sleeve 22 for winding and slitting the small-sized paper roll, and a driving roller 19 arranged in a front-to-back direction is arranged on the right side of the supporting base plate 1. When the deflection plate 20 is rotated to face the upper right, the two driven rollers 21 will fall on the outside of the driving roller 19. At this time, if the driving roller 19 rotates, the two driven rollers 21 will start to rotate.

[0027] In one case of this embodiment, a slot 23 cooperating with the second rotating rod 27 is provided on the side of the suspension plate 18 away from the supporting base plate 1. The slot 23 is located on the left side of the upper surface of the suspension plate 18, and the slot 23 is open at the top. Therefore, when the deflection plate 20 rotates counterclockwise, the second rotating rod 27 on the deflection plate 20 will fall into the slot 23, thereby achieving the effect of retracting the driven roller 21. The heights of the two driven rollers 21 are raised and disengaged from the driving roller 19, so as to prevent the driven rollers 21 from being pressed on the same position of the driving roller 19 for a long time. The problem of damage is solved, and a connecting head 28 is slidably connected to one side of the first rotating rod 26 and the second rotating rod 27 close to the center of the supporting base plate 1, and a stud 36 is provided at the end of the connecting head 28. Screw holes 35 are provided at the front and rear ends of the driven roller 21. First, the front and rear connecting heads 28 are separated, and the driven roller 21 can be placed between the two connecting heads 28. At this time, the connecting head 28 can be rotated so that the stud 36 is screwed into the screw hole 35, thereby realizing the effect of connecting the connecting head 28 and the driven roller 21, and realizing the effect of detachable connection of the driven roller 21.

[0028] In one case of the present embodiment, a limiting protrusion 29 is slidably connected to the side wall of the driven roller 21, and the limiting protrusion 29 is arranged in a front-to-back direction. Three limiting protrusions 29 are arranged on the outside of a driven roller 21 and are evenly distributed relative to the center of the driven roller 21. A fixing plate 31 is fixedly connected to the front and back sides of the interior of the driven roller 21, and a push rod 30 is slidably connected to the middle part of the fixing plate 31. A limiting disk 33 is arranged at one end of the push rod 30 close to the center of the driven roller 21, and a return spring 32 is arranged between the limiting disk 33 and the fixing plate 31. The return spring 32 will push the push rod 30 to move in a direction away from the center of the driven roller 21, and one end of the push rod 30 is rotatably connected to the top plate 34 on the outside of the limiting disk 33, and the other end of the top plate 34 is rotatably connected The limiting protrusion 29 is connected to the side of the center of the driven roller 21, so when the stud 36 is screwed into the screw hole 35 of the driven roller 21, the stud 36 will push the push rod 30 to move toward the center of the driven roller 21. At this time, the push rod 30 will push the limiting protrusion 29 outward through the top plate 34, so that the limiting protrusion 29 presses the small paper roll sleeve 22 tightly, thereby achieving the fixing of the small paper roll sleeve 22. When the stud 36 is separated from the driven roller 21, the return spring 32 will push the push rod 30 outward, and the push rod 30 pulls the limiting protrusion 29 to move toward the center of the driven roller 21 through the top plate 34. At this time, the limiting protrusion 29 is disengaged from the small paper roll sleeve 22, and the small paper roll sleeve 22 can be easily removed from the outside of the driven roller 21.

[0029] In one case of the present embodiment, vertical plates 37 are vertically arranged on both the front and rear sides of the right end of the supporting base plate 1, and the upper end of the vertical plate 37 is rotatably connected to the front and rear ends of the driving roller 19. In order to reduce the weight of the device, the driving roller 19 can be designed as a hollow structure and fixed by connecting rods and rods. A second driving motor 38 is arranged in the middle of the front vertical plate 37, and the output shaft of the second driving motor 38 is fixedly connected to the third bevel gear 39. The third bevel gear 39 is meshedly connected to the fourth bevel gear 40 connected to the front end of the driving roller 19. Therefore, the second driving motor 38 can rotate the driving roller 19 through gear transmission.

[0030] In one case of the present embodiment, a front-to-back guide roller 4 is arranged on the right side of the upper end of the L-shaped support frame 12, and the front and rear ends of the guide roller 4 are rotatably connected to the L-shaped support frame 12, and a front-to-back rotating shaft 5 is arranged above the guide roller 4, and the front and rear ends of the rotating shaft 5 are rotatably connected to the L-shaped support frame 12, and a plurality of sliding sleeves 6 are sleeved on the rotating shaft 5, and the outside of the sliding sleeve 6 is fixedly connected to the cutting wheel 7, so that the cutting wheel 7 can move forward and backward along the rotating shaft 5 through the sliding sleeve 6 to achieve the effect of adjusting the spacing, that is, the adjustment of the width of the paper after cutting, and A first drive motor 8 is arranged on the front side of the L-shaped support frame 12, and the output shaft of the first drive motor 8 is fixedly connected to the first bevel gear 9, and the first bevel gear 9 is meshedly connected to the second bevel gear 10 fixedly connected to the front end of the rotating shaft 5. The first drive motor 8 can rotate the rotating shaft 5 through gear transmission, so that the multiple cutting wheels 7 can rotate synchronously. A bushing is arranged between the sleeve 6 and the rotating shaft 5, and the bushing has a certain friction force. Therefore, after the sleeve 6 completes the front and rear position movement, the sleeve 6 itself will not move forward and backward when there is no external force.

[0031] In one case of the present embodiment, a clamping assembly 11 is arranged on the upper left side of the L-shaped support frame 12, and the clamping assembly 11 can fix the front and rear ends of the large-sized paper roll. The clamping assembly 11 includes a clamping rod 14 rotatably connected to the L-shaped support frame 12, and the opposite ends of the front and rear clamping rods 14 are slidably connected with a clamping head 13, and a clamping ring 16 is arranged in the middle of the clamping rod 14, and a clamping spring 15 is arranged between the clamping ring 16 and the clamping head 13. After the clamping heads 13 are separated to both sides, the large-sized paper roll can be placed between the two clamping heads 13. At this time, the clamping head 13 is released, and under the action of the clamping spring 15, the clamping head 13 will press the front and rear ends of the large-sized paper roll tightly to achieve the feeding effect.

[0032] During the implementation of this embodiment, the large-size paper roll that needs to be cut is first taken out, and the large-size paper roll is installed on the left side of the L-shaped support frame 12 through the clamping assembly 11.

[0033] Size adjustment processing, adjust the front and rear position of the cutting wheel 7 according to the required slitting width, rotate the deflection plate 20 counterclockwise so that the second rotating rod 27 falls into the slot 23, then take out the driven roller 21, and put the small paper roll sleeve 22 used for winding small-sized paper on the outside of the driven roller 21, adjust the front and rear position of the small paper roll sleeve 22 according to the cutting position, and after the adjustment is completed, connect the connecting head 28 to the driven roller 21. During the connection process, the limiting protrusion 29 will tighten the small paper roll sleeve 22, and connect the two driven rollers 21 to the first rotating rod 26 and the second rotating rod 27 respectively. At this time, the small paper roll sleeves 22 on the driven rollers 21 on the left and right sides are staggered front and back, so that the paper rolls that have been slit can be respectively put on the left and right driven rollers 21 one above and one below, which is convenient for subsequent material collection processing.

[0034] Cutting process, rotate the deflection plate 20 clockwise, and under the action of gravity, the two driven rollers 21 will fall to the upper left side of the driving roller 19, at this time, the free end of the paper of the large-size paper roll on the clamping assembly 11 can be pulled out, and the free end of the paper is passed between the cutting wheel 7 and the guide roller 4. After the paper extends a little to the right, start the first drive motor 8, and the cutting wheel 7 starts to rotate. The paper is manually pulled out to the right, the paper is cut, and the end of the free end of the paper is cut. At this time, the cutting wheel 7 will cut the large-size paper into multiple strips of paper with smaller widths. The operator wraps the free ends of these small-width strips of paper around the small paper roll sleeve 22, and ensures that two adjacent strips of paper are cut. The strip paper is respectively wound on the two small paper roll sleeves 22 on the left and right sides, and the second drive motor 38 is started. The second drive motor 38 drives the two driven rollers 21 to rotate at the same time through the driving roller 19. Therefore, the paper on the large-size paper roll on the left is cut into small-width strip paper and then wound on the small paper roll sleeve 22. As the number of paper layers wrapped outside the small paper roll sleeve 22 gradually increases, the two driven rollers 21 move upward adaptively. At this time, the slider 25 slides upward adaptively along the slide groove 24, and the deflection plate 20 also rotates counterclockwise adaptively by a certain angle, so that the paper rolls outside the two driven rollers 21 always keep in contact with the driving roller 19.

[0035] Unloading process: when the paper is cut, stop the first drive motor 8 and the second drive motor 38, rotate the deflection plate 20 counterclockwise, and the second rotating rod 27 falls into the slot 23. Rotate the connecting head 28, and the connecting head 28 is disengaged from the driven roller 21. Under the action of the reset spring 32, the limit protrusion 29 retracts toward the center of the driven roller 21. At this time, the limit protrusion 29 is disengaged from the inner wall of the small paper roll sleeve 22. The operator can easily remove the small paper roll sleeve 22 with the paper wound on it, and the unloading process is completed.

[0036] The present invention is applicable to a cutting device for decorative paper production. By setting a deflection plate 20 that moves up and down and rotates freely, the two driven rollers 21 always keep in contact with the driving roller 19 when the paper is continuously wound, so that the two driven rollers 21 can continuously wind the slit paper, so that the paper is also rolled after the slitting is completed, thereby improving the processing efficiency of the entire cutting.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
