Description

Technical Field

[0001] The invention relates to the technical field of slitting processing, and in particular to a high-speed slitting machine. Background Art

[0002] High-speed slitting machine is a high-efficiency and high-precision processing equipment, which is widely used in the processing departments of paper and cloth industries. It usually drags paper or cloth strips through the tool through a conveying structure, and then uses the tool to cut the paper or cloth strips into multiple parts of specific lengths, thereby completing the cutting process of paper or cloth strips.

[0003] After searching, the patent with publication number CN214569595U discloses a high-speed slitting machine. After the material tray in the device enters the conveying channel, it starts feeding. The material tray is transmitted to the middle of the conveying channel, and the material in the material tray is slit by the high-speed slitting mechanism on the bracket. Finally, it is sent to the end of the conveying channel and the slit material is recovered by the recovery device, which can meet the needs of enterprise automated production.

[0004] Although the existing device reduces the difficulty of loading, it is undoubtedly inconvenient for rolled paper or cloth strips. At the same time, due to the limitations of this loading method, the multiple material tray positions in the device cannot ensure the same spacing, which will affect the accuracy of the subsequent slitting process. In view of this, we propose a high-speed slitting machine. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0039] A high-speed slitting machine comprises a fixed seat 1, a fixed plate 2 is arranged on the right side of the fixed seat 1, the fixed plate 2 is an L-shaped structure, and a transmission component 3 is arranged between the fixed plate 2 and the fixed seat 1;

[0040] The transmission assembly 3 includes two transmission wheels 4 symmetrically rotatably connected between the fixed plate 2 and the fixed seat 1, a conveyor belt 5 connected between the outsides of the two transmission wheels 4, a flattening wheel 6 rotatably connected between the fixed plate 2 and the front side of the fixed seat 1, and a guide plate 7 fixed between the fixed plate 2 and the rear side of the fixed seat 1. The front wall of the guide plate 7 is in sliding contact with the outer wall of the conveyor belt 5. The guide plate 7 is also arranged in an inclined structure with the front side higher and the rear side lower. In this way, the processed paper or cloth strips on the conveyor belt 5 can be guided to the rear side of the device, and the staff only needs to place the external storage device at the position behind the guide plate to receive the finished product;

[0041] A cavity 8 is provided inside the fixed seat 1, and a driving mechanism 9 is provided inside the cavity 8. The driving mechanism 9 includes a moving block 10 slidably connected inside the cavity 8, two racks 11 symmetrically fixedly provided on the front wall of the moving block 10, and a half gear 12 meshingly connected to the two racks 11. The rotation of the half gear 12 can drive the moving block 10 to reciprocate through the two symmetrical racks 11. A motor 13 is coaxially fixedly connected to the left end of the half gear 12, a side plate 14 is fixedly provided on the right end of the rack 11, and a plurality of tooth columns 15 are rotatably connected to the bottom surface of the side plate 14 on the lower side in a linear and equidistant structure, and a transmission gear 16 meshingly connected to the tooth columns 15. Driven by the tooth columns 15, the transmission gear 16 can rotate.

[0042] A cutting assembly 17 is also installed at the rear of the cavity 8, and the cutting assembly 17 includes two sliders 18 symmetrically arranged at the rear of the cavity 8, a rotating shaft 19 fixed to the right end of the slider 18, a connecting rod 20 rotatably connected to the rotating shaft 19, a movable seat 21 hinged between the two connecting rods 20, a fixed rod 22 elastically connected to the right end of the rotating shaft 19 located on the upper side, and a blade 23 fixed on the bottom surface of the fixed rod 22.

[0043] Specifically, the cross section of the conveyor belt 5 is a U-shaped structure. Under such structural restrictions, the materials on the conveyor belt 5 of the device can be firmly restricted, which can not only block the materials from falling, but also limit the materials so that the cutting position remains perpendicular to the edge of the materials. The fixed plate 2 and the fixed seat 1 are both provided with a belt groove 24 that slides with the end of the conveyor belt 5. The belt groove is used to cover the edge of the conveyor belt 5 to prevent the blade 23 from being blocked. The outer walls on both sides of the conveyor belt 5 are equidistantly arranged with a plurality of toggle blocks A25, and the flattening wheel 6 is The flattening wheel 6 has a cross-shaped structure, and the spacing between the middle outer wall of the flattening wheel 6 and the concave position of the outer wall of the conveyor belt 5 is just enough for the material to pass through. The outer walls at both ends of the flattening wheel 6 are both annular and evenly spaced structures, and a plurality of toggle blocks B26 are fixed thereon. The toggle block A25 is meshingly connected with the toggle block B26. Under the meshing connection relationship between the two, the flattening wheel 6 can be driven during the movement of the conveyor belt 5 along the outer walls of the two transmission wheels 4, thereby producing a crushing effect on the paper or cloth strips on the surface of the conveyor belt 5, thereby achieving the flattening of the material and avoiding the problem of crooked cutting edges caused by material wrinkles.

[0044] Furthermore, the moving block 10 is a T-shaped structure with a triangular prism shape at the rear end. A bottom groove 27 that slides with the tooth column 15 is provided on the bottom surface of the side plate 14 on the lower side. The tooth column 15 can be completely rotated into the bottom groove 27. The tooth column 15 is rotatably connected to the lower end of the rear wall of the bottom groove 27 through a hinge shaft 28. Such a structure enables the rear wall of the bottom groove 27 to have a restrictive effect on the tooth column 15, so that when the moving block 10 moves forward, the tooth column 15 can support the transmission gear 16 to further drive the transmission wheel 4 on the front side to rotate, and then the conveyor belt 5 connected between the outsides of the two transmission wheels 4 will move and transport the materials placed on its top surface backward. A circular cavity 29 is provided on the right wall of the bottom groove 27 relative to the position of the hinge shaft 28, and a coil spring 30 is sleeved on the right end of the hinge shaft 28. The coil spring 30 The outer end is connected and fixed to the inner wall of the circular cavity 29. Under the setting of this structure, when the moving block 10 moves backward, the reaction force of the transmission gear 16 on the tooth column 15 will cause the tooth column 15 to rotate along the hinge shaft 28 toward the inside of the bottom groove 27. In this way, the moving block 10 will not cause the reversal of the transmission gear 16 when moving backward, which not only ensures that the conveyor belt 5 can continue to transport the material backward, but also allows the conveyor belt 5 to be in a stationary state when the cutting assembly 17 cuts the material, so that the blade 23 will not scratch the material. When the position of the tooth column 15 is away from the transmission gear 16, the tooth column 15 will return to its original position under the rotational force of the coil spring 30 and play the role of shifting the transmission gear 16 again when the moving block 10 moves forward. The transmission gear 16 is coaxially and fixedly connected to the transmission wheel 4 located on the front side.

[0045] Furthermore, an air duct 31 is coaxially fixedly connected between the motor 13 and the half gear 12. Under the drive of the motor 13, the half gear 12 and the air duct 31 will continuously rotate, and then the transmission component 3 and the cutting component 17 will be further controlled to operate alternately under the action of the driving mechanism 9. The air duct 31 is rotatably connected to the left wall of the fixed seat 1. The right part of the air duct 31 is an open structure, and its left end is a closed structure and coaxially fixedly connected to the motor 13. Both ends of the air duct 31 are truncated cone structures with a large inner side and a small outer side. A box body 32 is fixedly provided on the left wall of the fixed seat 1 relative to the air duct 31. The box body 32 The right part of the box body 32 is originally an open structure. When fixed with the fixing base 1, its right part is also sealed. The right wall of the motor 13 is connected and fixed to the left wall of the box body 32. The output end of the motor 13 passes through the right wall of the box body 32 and extends to the inside thereof and is coaxially fixedly connected with the air duct 31. A movable door 33 is hinged on the front wall of the box body 32. A filter screen 34 is embedded in the middle of the movable door 33, so that the inside of the box body 32 can exchange air from the filter screen 34 to the outside.

[0046] Furthermore, a turbofan 35 is coaxially fixedly connected to the inside of the air duct 31. When the motor 13 drives the air duct 31, the turbofan 35 will rotate synchronously. At this time, the turbofan 35 will produce an exhaust effect, so that the air in the air duct 40 enters the air duct 32 from the conduit 38. The left part of the circumferential outer wall of the air duct 31 is annularly and evenly spaced with a plurality of through grooves 36. With this design, the wind sucked into the air duct 31 by the turbofan 35 can be blown out directly from the position of the through grooves 36, and under the cone structure at the left end of the air duct 31, the sucked air can enter the inside of the box 32 in a straight line, avoiding the problem of dust remaining in the air duct 31 due to the detour. A through hole 37 connected to the right open end of the air duct 31 is opened in the middle part of the half gear 12. The through hole 37 is coaxially rotatably connected with the conduit 38, and a support block 39 is fixed on the fixed plate 2 at a position relative to the end of the conduit 38.

[0047] Furthermore, the outer wall of the support block 39 is in sliding contact with the inner wall of the conveyor belt 5, the interior of the support block 39 is hollow to form an air duct 40, the right end of the conduit 38 penetrates the left wall of the support block 39 and extends to the interior thereof and is connected and fixed thereto, the top surface of the air duct 40 is linearly and evenly spaced with a plurality of air inlets 41, and a plurality of through holes 42 are evenly arranged at positions relative to the air inlets 41 on the conveyor belt 5, when the air in the air duct 40 is sucked away by the turbo fan 35, the external air is sucked in from the through holes 42 on the conveyor belt 5, which will have a certain effect on the materials placed on the conveyor belt 5 Because there is only a sliding contact between the conveyor belt 5 and the support block 39, the outside air can also enter the air inlet 41 through the gap between the conveyor belt 5 and the support block 39, avoiding the problem of excessive suction force damaging the material due to the blockage of the through hole 42 by the material. At the same time, this structural design can also allow the debris and dust generated when the paper or cloth strips on the device are cut to be sucked into the box body 32, which can effectively reduce the dust generated during the operation of the device, protect the respiratory health of the staff, and reduce the difficulty of cleaning the device.

[0048] It is worth mentioning that a slide groove 43 slidably connected to the slider 18 is provided on the left wall of the cavity 8, and a movable groove 44 slidably matched with the movable seat 21 is provided on the left wall of the cavity 8. The rear end of the movable block 10 is squeezed and matched with the front wall of the movable seat 21, and a connecting groove 45 is provided on the rear part of the right wall of the cavity 8. Two compression springs 46 are symmetrically fixed between the rear wall of the movable seat 21 and the rear wall of the movable groove 44. During the backward movement of the movable block 10, an extrusion effect will be produced on the front wall of the movable seat 21. Therefore, under the setting of the slide groove 43 and the movable groove 44, the slider 18 and the movable seat 21 in this device will not deviate from the original moving line, and then the two connecting rods 20 will rotate to adapt to the change of their positions. On the other hand, when the slider 18 located on the upper side is displaced, the rotating shaft 19 rotatably connected to it will also be displaced, and will drive the fixed rod 22 elastically connected to the rotating shaft 19 to move. The descent of the fixed rod 22 will prompt the blade 23 to descend and then cut the material on the conveyor belt 5.

[0049] It is worth mentioning that a guide block 47 is fixedly provided at the right end of the rotating shaft 19 on the upper side, a guide groove 48 slidably connected to the guide block 47 is provided on the left wall of the fixed rod 22, a return spring 49 is sleeved on the outer wall of the guide block 47, and a plurality of triangular grooves 50 are provided on the bottom surface of the blade 23 in a linear and evenly spaced structure. The provision of the triangular grooves 50 enables the blade 23 to more easily penetrate the surface of the material when cutting the material.

[0050] It is worth noting that a vertical groove 51 is provided on the inner wall of the fixed plate 2, and the right end of the fixed rod 22 is in sliding contact with the right wall of the vertical groove 51, and an extrusion block 52 is fixed to the lower part of the right wall of the vertical groove 51. The right end of the fixed rod 22 and the extrusion block 52 are both hemispherical structures, and the right end of the fixed rod 22 is extruded and matched with the extrusion block 52. When the fixed rod 22 descends, its end will be squeezed by the extrusion block 52 first, so that it will compress the return spring 49 to the left along the sliding cooperation direction of the guide block 47 and the guide groove 48 to tighten. When the fixed rod 22 moves to the bottom of the extrusion block 52, it will vibrate left and right under the elastic force of the return spring 49, and then it can produce a sawing effect on the position to be cut of the material, so that the device can cut the material more easily.

[0051] Working principle: The staff can place the paper or cloth strips to be cut on the conveyor belt 5 in the transmission component 3 of the device, and then use the driving mechanism 9 to drive the transmission component 3 to transport the material to the rear. During the process, the flattening wheel 6 can smooth the material, and at the same time, the turbo fan 35 can also adsorb the material on the conveyor belt 5. Subsequently, the transmission component 3 and the cutting component 17 can move alternately under the drive of the driving mechanism 9, so as to achieve the effect of first transporting a section of material and then cutting the material behind the lower blade 23. During the process, the turbo fan 35 can also suck the debris and dust generated during cutting into the box 32.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
