Description

Technical Field

[0001] This utility model relates to the technical field of material roll edge cutting device, and in particular to a non-powered follow-up edge cutting device. Background Technology

[0002] The main function of a material roll is to contain and transport materials. The cylindrical design of the material roll can reduce the resistance of the material during the flow process, speed up the flow rate, and allow the material to flow smoothly in it, thereby shortening the production cycle, improving the efficiency and quality of the production process, and also facilitating the pushing and plasticizing of the support rod.

[0003] Currently, if a section of a material roll collapses during transportation, manual handling of the collapsed area is required before materials can be loaded again and normal production can resume.

[0004] The existing technical solutions have the following drawbacks: when the material roll collapses, it is necessary to manually tear off all the material at the collapsed area until there is no collapsed area, and then reload the material and resume normal production. This process delays production time and wastes manpower. Therefore, it is necessary to set up an additional non-powered follow-up cutting device to improve the efficiency and quality of the production process. Utility Model Content

[0005] The purpose of this invention is to provide a non-powered follow-up cutting device to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A non-powered follow-up edge cutting device includes a rotating shaft, with fixed frames at both ends of the rotating shaft. Fixed devices are symmetrically arranged on the rotating shaft. Each fixed device includes a fixed sleeve, a bushing, and a first coil spring. The bushing is sleeved on the rotating shaft and has a first bearing. The fixed sleeve is sleeved on the first bearing, and the first coil spring is sleeved on the bushing. The outer ring of the first coil spring is fixedly connected to the inner ring of the fixed sleeve.

[0008] A connecting plate is fixedly installed on the outside of the fixed sleeve. A round rod parallel to the axis of rotation is passed through the side of the connecting plate away from the fixed sleeve. A fixed plate is fixedly installed at one end of the round rod, and a pressure roller is rotatably installed at the other end of the round rod.

[0009] A cutting disc is rotatably mounted on the center position of the side of the fixed plate opposite to the round rod, and a protective plate is slidably mounted on the side of the fixed plate opposite to the round rod.

[0010] By adopting the above technical solution, a bushing is fitted onto the rotating shaft, and a first coil spring is fitted onto the bushing. The first coil spring is fixedly connected to the inner ring of the fixed sleeve. The first coil spring will generate a counterclockwise force to drive the fixed sleeve to rotate. Because a connecting plate is fixedly installed on the outside of the fixed sleeve, a round rod parallel to the axis of the rotating shaft is inserted on the side of the connecting plate away from the fixed sleeve. A pressure roller is installed at one end of the round rod, which will cause the pressure roller to move centripetally with the rotation of the fixed sleeve. When the protective plate contacts the surface of the material roll, it is subjected to a relative force and slides in the centrifugal direction. This causes the cutting disc, which is rotated and installed at the center of the side of the fixed plate away from the round rod, to contact the material roll. The cutting disc cuts the material roll. The required length of material is determined by manually pulling the material roll, which rotates the material roll and causes the cutting disc to rotate accordingly, achieving a better cutting effect on the material and achieving the technical effect of non-powered follow-up.

[0011] In a further embodiment, a second coil spring is sleeved on the middle section of the round rod, a first sleeve is sleeved on the second coil spring, and a connecting rod with an axial direction perpendicular to the round rod is provided on the outer side of the first sleeve. An auxiliary pressure wheel is rotatably installed on the end of the connecting rod away from the round rod.

[0012] By adopting the above technical solution, the second coil spring, which is sleeved in the middle section of the round rod, is fixed inside the first sleeve. The second coil spring will generate a force that rotates counterclockwise, forcing the first sleeve to rotate counterclockwise. This causes the connecting rod, which is set on the outside of the first sleeve and whose axis is perpendicular to the round rod, to move centripetally. This causes the auxiliary pressing wheel, which is rotatably mounted on the connecting rod at the end away from the round rod, to move centripetally, making the auxiliary pressing wheel fit more closely to the surface of the material. This prevents slight collapse of the rolled material from being missed during the operation of the non-powered follow-up cutting device, and greatly improves the working efficiency and quality of the non-powered follow-up cutting device.

[0013] In a further embodiment, the protective plate is symmetrically provided with limit blocks on the side near the fixed plate, the fixed plate is provided with limit grooves corresponding to the limit blocks, and the cross-section of the limit blocks is cylindrical.

[0014] By adopting the above technical solution, the limiting groove on the fixed plate and the limiting block on the protective plate cooperate with each other to restrict the protective plate to only centrifugal or centripetal motion, which can improve the safety of the unpowered follow-up cutting device and prevent personnel from being accidentally injured.

[0015] In a further embodiment, a groove is provided on one side of the fixing plate, a protrusion is provided on the side of the fixing plate near the protective plate, a circular hole corresponding to the protrusion is provided on the side of the protective plate near the fixing plate, an upper travel limit rod is detachably inserted into the circular hole, and a lower travel limit rod corresponding to the groove is provided on the side of the protective plate near the fixing plate.

[0016] By adopting the above technical solution, the upper stroke limit rod on the side of the protective plate near the fixed plate will be restricted by the protrusion on the side of the fixed plate near the protective plate, so the protective plate cannot make excessive centrifugal movement. The lower stroke limit rod, which is inserted through the round hole on the protective plate, will be restricted by the groove on the side of the fixed plate, so the protective plate cannot make excessive centripetal movement.

[0017] In a further embodiment, the bottom end of the protective plate is provided with auxiliary wheels.

[0018] By adopting the above technical solution, when the auxiliary wheel at the bottom of the protective plate is subjected to the relative force generated by the movement of the material roll, the auxiliary wheel can drive the protective plate to make centrifugal motion.

[0019] In a further embodiment, a laser calibrator for positioning is provided on one side of the fixing plate.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. By setting the cross-section of the limiting block to a cylindrical shape, the sliding friction between the limiting block and the limiting groove can be reduced, thus minimizing the obstruction of the centrifugal or centripetal motion of the protective plate. Attached Figure Description

[0028] Example 1:

[0029] like Figures 1-3 As shown, a non-powered follow-up edge cutting device includes a rotating shaft 1, with fixed frames 20 at both ends of the rotating shaft 1. Fixed devices 2 are symmetrically arranged on the rotating shaft 1. The fixed devices 2 include a fixed sleeve 21, a bushing 22, and a first coil spring 23. The bushing 22 is sleeved on the rotating shaft 1 and a first bearing is sleeved on the bushing 22. The fixed sleeve 21 is sleeved on the first bearing, and the first coil spring 23 is sleeved on the bushing 22. The outer ring of the first coil spring 23 is fixedly connected to the inner ring of the fixed sleeve 21.

[0030] A connecting plate 3 is fixedly installed on the outside of the fixed sleeve 21. A round rod 4 parallel to the axis of the rotating shaft 1 passes through the side of the connecting plate 3 away from the fixed sleeve 21. A fixed plate 5 is fixedly installed at one end of the round rod 4, and a pressure roller 6 is rotatably installed at the other end of the round rod 4.

[0031] A cutting blade 18 is rotatably mounted on the center position of the side of the fixed plate 5 away from the round rod 4, and a protective plate 7 is slidably mounted on the side of the fixed plate 5 away from the round rod 4.

[0032] A second coil spring 19 is sleeved in the middle section of the round rod 4. A first sleeve 8 is sleeved on the second coil spring 19. A connecting rod 9 with an axial direction perpendicular to the round rod 4 is provided on the outer side of the first sleeve 8. An auxiliary pressure wheel 10 is rotatably installed on the end of the connecting rod 9 away from the round rod 4. Limiting blocks 11 are symmetrically provided on the side of the protective plate 7 near the fixed plate 5. A limiting groove corresponding to the limiting block 11 is provided on the fixed plate 5. The cross section of the limiting block 11 is cylindrical 12. A groove is provided on one side of the fixed plate 5. A protrusion 13 is provided on the side of the fixed plate 5 near the protective plate 7. A round hole corresponding to the protrusion 13 is provided on the side of the protective plate 7 near the fixed plate 5. An upper stroke limiting rod 14 is detachably inserted into the round hole.

An auxiliary wheel 16 is provided at the bottom of the protective plate 7. A laser calibrator 17 for positioning is provided on one side of the fixed plate 5.

[0033] Specific implementation process: When the non-powered follow-up cutting device is in contact with the material roll, the first coil spring 23, which is sleeved on the rotating shaft 1 and fixedly installed inside the fixed sleeve 21, will drive the fixed sleeve 21 to rotate counterclockwise. The fixed sleeve 21 will drive the connecting plate 3 on its outer side to move centripetally. The round rod 4 passing through the connecting plate 3 will also transmit the force of counterclockwise movement to the pressing roller 6. The second coil spring 19, which is fixed in the middle section of the round rod 4 inside the first sleeve 8, will also generate a force to move counterclockwise, thereby causing the auxiliary pressing roller 10 fixedly installed on the outer side of the first sleeve 8 to move centripetally, thus achieving the effect of non-powered follow-up. During the operation of the non-powered follow-up cutting device, if the material on the surface of the material roll collapses locally, the material roll will rotate clockwise. The auxiliary wheel 16 at the bottom of the protective plate will be subjected to the opposite force generated by the material roll, which will drive the protective plate 7 to move centrifugally. The cutting disc 18 will contact the material roll under the action of gravity and then cut the material roll, thus achieving the effect of non-powered follow-up cutting.
