Abstract
Description
Technical Field
[0001] This application relates to the field of slitting machine technology, and in particular to a slitting machine. Background Technology
[0002] In the production of adhesive tapes, protective films, and paper products, it is usually necessary to use a roll cutter to cut a regular large roll of material into specified widths.
[0003] Chinese Patent CN105034049A discloses a tape cutter, which includes a rotating shaft mounted on a frame for threading tape rolls, rotating about its axis; a movable cutting table mounted on the frame for cutting tape rolls; a first driving device mounted on the frame for driving the cutting table; and a blocking part sleeved on one end of the rotating shaft. By adding a blocking part to the rotating shaft, the tape cutter does not need to have a pre-reserved portion when cutting, and the cutter can cut all the way to the end of the tape roll without producing any tail material.
[0004] However, the cutter in this coil cutter is set perpendicular to the material shaft, meaning the cutter can only cut in a direction perpendicular to the material shaft. When the perpendicular cutter cuts hard materials such as protective film, the lateral force on the blade is concentrated at a single point at the moment of contact between the cutter and the protective film. The hard protective film is difficult to evenly distribute this force in a short time, which leads to stress concentration at the cutting position. This results in unevenness on the cut surface, reducing the cutting accuracy and surface quality of the protective film, and consequently reducing the cutting quality of the coil cutter, which is a significant shortcoming. Utility Model Content
[0005] In order to improve the cutting quality of hard materials by the cutting tool, this application provides a roll cutter.
[0006] The slitting and rolling machine provided in this application adopts the following technical solution:
[0007] A coil cutter includes a frame with a placement shaft rotatably connected to the frame for placing a material cylinder. A movable plate is slidably connected to the frame along its length. A cutting assembly is mounted on the movable plate. The cutting assembly includes a support plate, a mounting plate rotatably connected to the support plate, and a cutter rotatably connected to the mounting plate. An angle adjustment assembly is provided on the support plate. A sliding groove is formed on the support plate along the axis of the placement shaft. The angle adjustment assembly includes an adjusting screw rotatably connected to the sliding groove. A hinge seat is threaded onto the adjusting screw and slidably engages with the sliding groove. The hinge seat is hinged to the mounting plate. A first motor is provided on the movable plate to drive the adjusting screw to rotate.
[0008] By adopting the above technical solution, when cutting hard materials such as protective films, the first motor drives the adjusting screw to rotate. Under the limiting guidance of the sliding groove, the adjusting screw drives the hinge seat to slide along the sliding groove. The hinge seat drives the mounting plate to rotate around the rotation connection point between it and the bearing plate, which in turn drives the tool to rotate, so that the tool cuts the material at an inclined angle. At this time, the lateral force on the blade is dispersed, avoiding stress concentration at the cutting position, thereby improving the cutting quality of hard materials.
[0009] Optionally, the mounting plate is provided with guide posts, and the bearing plate is provided with arc grooves that slide with the guide posts.
[0010] By adopting the above technical solution, the sliding fit between the guide post and the arc groove improves the stability of the mounting plate during rotation. At the same time, the length of the arc groove limits the rotation angle of the mounting plate, preventing excessive rotation of the mounting plate from causing the tool angle adjustment to exceed the reasonable range.
[0011] Optionally, the bottom surface of the support plate is provided with a guide block, and the surface of the movable plate is provided with a guide groove that slides with the guide block. The guide groove is parallel to the radial direction of the placement axis. The movable plate is provided with a thickness adjustment component, which drives the support plate to slide along the guide groove.
[0012] By adopting the above technical solution, when the thickness of the material being cut changes, the thickness adjustment component drives the support plate to slide along the guide groove. The sliding of the support plate causes the distance between the tool and the placement shaft to change, thereby allowing the tool to move closer to or further away from the placement shaft, thus achieving adjustment of the cutting thickness and improving the applicability of the roll cutter.
[0013] Optionally, the thickness adjustment assembly includes multiple rack plates disposed on the bottom surface of the support plate, a drive groove is provided on the movable plate, the rack plates are slidably disposed inside the drive groove, a drive shaft is rotatably connected inside the drive groove, a gear corresponding to each of the multiple rack plates is coaxially disposed on the drive shaft, the gear meshes with the corresponding rack plate, and a second motor is disposed on the outer surface of the movable plate to drive the drive shaft to rotate.
[0014] By adopting the above technical solution, when it is necessary to adjust the distance between the cutter and the placement shaft, the second motor is started. The second motor drives multiple gears to rotate synchronously through the drive shaft. The gears drive the meshing rack plate to slide in the drive groove, thereby driving the cutting component on the support plate to move closer to or away from the placement shaft, thereby realizing the adjustment of the distance between the cutter and the placement shaft, so that the cutting thickness of the cutter meets the material thickness specifications of different materials.
[0015] Optionally, the frame is provided with a support assembly, which includes a fixed plate on the frame, a support plate hinged to the end of the fixed plate, a support cover rotatably engaging with the end of the placement shaft on the support plate, a support cylinder on the frame, and a piston rod of the support cylinder hinged to the outer surface of the support plate. When the support plate rotates to be parallel to the fixed plate, the end of the placement shaft is rotatably disposed inside the support cover.
[0016] By adopting the above technical solution, when the worker loads the material, the support cylinder pulls the support plate to rotate towards the fixed plate, avoiding interference between the support plate and the loading path of the placement shaft. After loading is completed, the support cylinder pushes the support plate to rotate away from the fixed plate. During the rotation of the support plate, the support cover gradually approaches the placement shaft and eventually rotates and connects with the end of the placement shaft, thereby forming effective support for the end of the placement shaft. This improves the stability of the placement shaft during the cutting process, reduces the shaking or eccentricity of the placement shaft caused by insufficient support, and further improves the cutting quality.
[0017] Optionally, a pusher ring is slidably sleeved on the placement shaft, and a moving groove is opened on both radially opposite sides of the pusher ring. A plug-in plate is slidably connected inside the moving groove. A plug-in groove is opened on the outer surface of the placement shaft to engage with the plug-in plate. A retaining spring is provided in the moving groove, and the elastic force of the retaining spring drives the plug-in plate to insert into the plug-in groove.
[0018] By adopting the above technical solution, during the cutting process, the elastic force of the retaining spring drives the insert plate to insert into the insert groove. The insert engagement fixes the pusher ring on the placement shaft. At this time, the pusher ring can position and retain the material cylinder, preventing axial movement of the material cylinder on the placement shaft and ensuring the stability of the cutting process. After the cutting is completed, the worker overcomes the elastic force of the retaining spring and pulls the two insert plates to disengage them from the insert groove. Then, the pusher ring is pushed along the axis of the placement shaft. During the movement of the pusher ring, the cut material segments are pushed onto the placement shaft, thereby achieving rapid unloading in one go. There is no need to manually remove multiple material segments from the cylinder, which improves the convenience of worker operation.
[0019] Optionally, the plug-in plate has a receiving groove, and a hook is slidably connected inside the receiving groove. The outer surface of the pusher ring is provided with a limiting post that engages with the hook. The limiting post has a T-shaped cross-section. When the hook engages with the limiting post, the plug-in plate disengages from the plug-in groove.
[0020] By adopting the above technical solution, when material needs to be unloaded, the worker overcomes the elastic force of the retaining spring and pulls the hook outward to hook it onto the limiting post. When the hook moves, it pulls the plug plate away from the plug slot, thereby releasing the fixed state of the push ring. At the same time, the T-shaped limiting post effectively prevents the hook from accidentally disengaging during the sliding process, ensuring that the plug plate is always detached from the plug slot during the movement of the push ring. This allows the worker to operate the push ring with one hand, further improving the convenience of the worker's operation.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. This application sets up an angle adjustment component, which drives the cutter to rotate, so that the cutter cuts the material at an inclined angle. At this time, the lateral force on the cutting edge is dispersed, avoiding stress concentration at the cutting position, thereby improving the cutting quality of hard materials.
[0023] 2. By setting up a thickness adjustment component, when the thickness of the material being cut changes, the thickness adjustment component drives the support plate to slide along the guide groove. The sliding of the support plate causes the distance between the tool and the placement shaft to change, thereby moving the tool closer to or further away from the placement shaft, thus achieving adjustment of the cutting thickness and improving the applicability of the roll cutter.
[0024] 3. This application sets up a pusher ring. After cutting, the worker pushes the pusher ring along the placement shaft axis. During the movement of the pusher ring, the cut material segments are pushed to the placement shaft, thereby achieving rapid material unloading in one go. There is no need to manually remove the multiple material segments, which improves the convenience of worker operation. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0031] This application discloses a roll cutter.
[0032] Reference Figure 1 A cutting and rolling machine includes a frame 1, a placement shaft 2 for placing a material cylinder is rotatably connected to the frame 1, a moving plate 3 is slidably connected to the frame 1 along the axial direction of the placement shaft 2, a cutting assembly 4 for cutting the material cylinder is provided on the moving plate 3, and a driving device (not shown in the figure) is installed on the frame 1. In this embodiment, the driving device is a track. The driving device drives the moving plate 3 to move along the length direction of the frame 1 to complete multiple cuts of the entire material cylinder.
[0033] Reference Figure 1 A support assembly 5 is provided on the frame 1. The support assembly 5 includes a fixed plate 51 fixedly installed on the frame 1. A support plate 52 is hinged to the end of the fixed plate 51. A support cover 53 is fixedly installed on the support plate 52. A support cylinder 54 is fixedly installed on the frame 1. The piston rod of the support cylinder 54 is hinged to the outer surface of the support plate 52. When the support plate 52 rotates to be parallel to the fixed plate 51, the end of the placement shaft 2 extends into the support cover 53 and is rotatably connected inside the support cover 53.
[0034] Before feeding, the support cylinder 54 pulls the support plate 52 to keep it perpendicular to the fixed plate 51, so as to avoid the support plate 52 interfering with the feeding path of the material cylinder. Then, the worker puts the material cylinder on the outer surface of the placement shaft 2. After feeding is completed, the support cylinder 54 is started. The support cylinder 54 pushes the support plate 52 to rotate away from the fixed plate 51. During the rotation of the support plate 52, the support cover 53 gradually approaches the placement shaft 2. Finally, the end of the placement shaft 2 extends into the support cover 53 to form support for the end of the placement shaft 2, thereby improving the stability of the placement shaft 2 during the material cylinder cutting process.
[0035] Reference Figure 1 and Figure 2 The cutting assembly 4 includes a support plate 41 mounted on a movable plate 3. A mounting plate 42 is rotatably connected to the support plate 41. A cutting tool 43 is rotatably connected inside the mounting plate 42. A cutting motor (not shown in the figure) that drives the cutting tool 43 to rotate is fixedly mounted on the outer surface of the mounting plate 42. During cutting, the cutting tool 43 is rotated by the driving of the cutting motor to achieve the cutting of the material cylinder.
[0036] Reference Figure 1 and Figure 2 An angle adjustment assembly 6 is provided on the support plate 41. The angle adjustment assembly 6 includes an adjustment screw 61, a hinge seat 62, and a first motor 63. The support plate 41 has a sliding groove 411 along the axis of the placement shaft 2. The adjustment screw 61 is rotatably connected inside the sliding groove 411. The hinge seat 62 is slidably connected inside the sliding groove 411 and threadedly connected to the adjustment screw 61. The hinge seat 62 is hinged to the mounting plate 42. The first motor 63 is fixedly installed on the outer surface of the support plate 41. The output shaft of the first motor 63 is coaxially fixedly connected to the adjustment screw 61.
[0037] Reference Figure 1 and Figure 2 The mounting plate 42 is fixedly connected to a guide post 421 at one end near the placement shaft 2. The bearing plate 41 is provided with an arc groove 412 that slides with the guide post 421. In this embodiment, when the angle adjustment component 6 drives the guide post 421 to move to the end of the arc groove 412, the angle between the cutter 43 and the radial direction of the placement shaft 2 is 3°.
[0038] When the material on the barrel is a hard material such as a protective film, after the material is loaded, the worker starts the first motor 63. The first motor 63 drives the adjusting screw 61 to rotate. Under the limiting guidance of the sliding groove 411, the adjusting screw 61 drives the hinge seat 62 to slide along the sliding groove 411. The hinge seat 62 drives the mounting plate 42 to rotate around the rotation connection point between it and the bearing plate 41, which in turn drives the cutter 43 to rotate, so that the cutter 43 cuts the material at an inclined angle. At this time, the lateral force on the blade is dispersed, avoiding stress concentration at the cutting position, thereby improving the cutting quality of hard materials.
[0039] Reference Figure 2 and Figure 3 A guide block 413 is fixedly connected to the bottom surface of the support plate 41 near the center. A guide groove 31 is opened on the surface of the moving plate 3 to slide with the guide block 413. The guide groove 31 is parallel to the radial direction of the placement shaft 2. A thickness adjustment component 7 is provided on the moving plate 3. The thickness adjustment component 7 includes multiple rack plates 71 fixedly connected to the bottom surface of the support plate 41. In this embodiment, there are two rack plates 71, and the two rack plates 71 are respectively arranged on both sides of the guide block 413.
[0040] Reference Figure 2 and Figure 3 The movable plate 3 has a drive groove 32. The rack plate 71 is slidably connected inside the drive groove 32. The drive shaft 72 is rotatably connected inside the drive groove 32. The drive shaft 72 is coaxially fixedly connected to a gear 73 corresponding to a plurality of rack plates 71. The gear 73 meshes with the corresponding rack plate 71. A second motor 74 is fixedly installed on the outer surface of the movable plate 3. The output shaft of the second motor 74 is coaxially fixedly connected to the drive shaft 72.
[0041] When the thickness of the material being cut changes, the second motor 74 is started. The second motor 74 drives multiple gears 73 to rotate synchronously through the drive shaft 72. The gears 73 drive the meshing rack plate 71 to slide in the drive groove 32. Under the guidance of the guide block 413 and the guide groove 31, the rack plate 71 drives the cutting component 4 on the support plate 41 to move closer to or away from the placement shaft 2, thereby adjusting the distance between the cutter 43 and the placement shaft 2, so that the cutting thickness of the cutter 43 can meet the material thickness specifications of different thicknesses.
[0042] Reference Figure 4 The placement shaft 2 is slidably fitted with a pusher ring 8 along the axial direction. The pusher ring 8 has a moving groove 81 on both sides of the radial direction. The moving groove 81 is slidably connected with a plug plate 9. The outer surface of the placement shaft 2 is provided with a plug groove 21 that is inserted and matched with the plug plate 9. A retaining spring 10 is provided in the moving groove 81. One end of the retaining spring 10 is fixedly connected to the inner side wall of the moving groove 81 away from the placement shaft 2, and the other end is fixedly connected to the plug plate 9. The elastic force of the retaining spring 10 drives the plug plate 9 to insert into the plug groove 21.
[0043] Before feeding the material, the worker first overcomes the elastic force of the clamping spring 10 to pull the plug plate 9, then puts the pusher ring 8 on the placement shaft 2 and pulls the pusher ring 8 along the axial direction of the placement shaft 2. When the plug plate 9 moves to the plug groove 21, the elastic force of the clamping spring 10 drives the plug plate 9 to insert into the plug groove 21. The pusher ring 8 is fixed on the placement shaft 2 through the plug-in engagement. Then the worker pushes the material cylinder to abut against the pusher ring 8. During the cutting process, the pusher ring 8 can position and clamp the material cylinder to prevent the material cylinder from moving axially on the placement shaft 2 and ensure the stability of the cutting process.
[0044] Reference Figure 4 Each plug plate 9 has a receiving groove 91 along its length. A hook 92 is slidably connected inside the receiving groove 91. A limiting post 82 corresponding to the two hooks 92 is fixedly connected on the push ring 8. The two limiting posts 82 are respectively set on both sides of the push ring 8. The cross-section of the limiting post 82 is T-shaped. The limiting post 82 hooks and engages with the corresponding hook 92. When the hook 92 hooks onto the limiting post 82, the plug plate 9 disengages from the plug groove 21.
[0045] After the entire section of the material cylinder is cut, the worker overcomes the elastic force of the retaining spring 10 and pulls the hook 92 outward to hook it onto the limiting post 82. When the hook 92 moves, it pulls the plug plate 9 away from the plug slot 21, thereby releasing the fixed state of the push ring 8. Then, the push ring 8 is pushed along the axis of the placement shaft 2. During the movement of the push ring 8, the cut material sections are pushed onto the placement shaft 2, thereby achieving rapid material feeding in one go. There is no need to manually remove the multiple sections of the material cylinder, which improves the convenience of the worker's operation.
[0046] The implementation principle of a cutting and rolling machine according to an embodiment of this application is as follows: When the material on the cylinder is a hard material such as a protective film, after the material is loaded, the worker starts the first motor 63. The first motor 63 drives the adjusting screw 61 to rotate. Under the limiting guidance of the sliding groove 411, the adjusting screw 61 drives the hinge seat 62 to slide along the sliding groove 411. The hinge seat 62 drives the mounting plate 42 to rotate around the rotation connection point between it and the bearing plate 41, thereby driving the cutter 43 to rotate, so that the cutter 43 cuts the material at an inclined angle. At this time, the lateral force on the blade is dispersed, avoiding stress concentration at the cutting position, thereby improving the cutting quality of hard materials.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
