Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a dust-free slitting machine. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide raw materials (such as paper, film, mica tape, non-woven fabric, metal strip, etc.) into multiple narrow strips. Its core function is to achieve quantitative slitting and winding of roll materials through a high-precision cutting and winding system.

[0003] In the precision slitting of materials such as film, paper, and metal foil, the accuracy of the circular blade spacing directly affects the consistency of the cut strip width. Traditional installation methods have the following drawbacks: low positioning accuracy, relying on manual measurement with vernier calipers, which is prone to cumulative errors due to visual errors or tool misalignment; poor fixing stability, the blade is prone to slippage under force when tightening the blade fixing bolts, requiring manual support, which increases labor costs and poses a risk of scratches; in addition, repeated calibration and fixing of the circular blades makes the process cumbersome and affects the efficiency of equipment debugging.

[0004] While existing technologies employ laser ranging or electronic rulers, these methods are costly and lack physical limiting structures, failing to fundamentally solve the problem of blade slippage. Therefore, there is an urgent need for a dust-free slitting machine that can precisely control the spacing between circular blades and improve the efficiency of circular blade installation.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address the issues of low installation efficiency due to the need for multiple measurements and calibrations during the installation of the circular blades in existing slitting machines, and the ease with which slippage can occur due to the lack of a positioning structure when fixing the circular blades, this invention provides a dust-free slitting machine that facilitates quick and accurate determination of the circular blade installation spacing and is highly practical.

[0007] The dust-free slitting mechanism provided by this utility model adopts the following technical solution: A dust-free slitting machine includes a cutter shaft and circular cutters fixed on the cutter shaft. A measuring rod is provided above the cutter shaft, and the side wall of the measuring rod is provided with scale markings for measuring the installation spacing of the circular cutters. A first clamping plate and a second clamping plate are sleeved on the measuring rod, clamping the circular cutters on both sides to achieve positioning and fixing of the circular cutters. An external threaded ring is fixed to the upper side wall of the first clamping plate, and four extrusion arc plates are fixed to the side wall of the external threaded ring. The extrusion arc plates are located outside the measuring rod, and an internal threaded ring is sleeved on the outside of the extrusion arc plates. One end of the internal threaded ring is threaded to the outside of the external threaded ring. An extrusion ring is fixed to the other end of the internal threaded ring, and the extrusion ring is located on one side of the extrusion arc plate. By turning the internal threaded ring, the extrusion ring is moved on the external threaded ring, driving the extrusion arc plate to press tightly against the measuring rod, thereby locking the first clamping plate. The second clamping plate is symmetrically arranged with the first clamping plate.

[0008] Furthermore, a socket hole is provided on the upper side wall of the first clamping plate, through which the measuring rod passes, allowing the first clamping plate to slide along the measuring rod; the external threaded ring is located outside the socket hole.

[0009] Furthermore, the top and bottom surfaces of the measuring rod are symmetrically provided with a first positioning groove and a second positioning groove, and the top of the first clamping plate is provided with a threaded hole, into which a positioning screw is screwed; the lower end of the positioning screw extends to the inner side of the sleeve hole and engages with the first positioning groove.

[0010] Furthermore, an extrusion pad is fixed to the side wall edge of the extrusion arc plate, and the extrusion pad is made of elastic rubber; one side wall of the extrusion arc plate is an inclined surface, which facilitates radial extrusion deformation by the extrusion ring.

[0011] Furthermore, the internal threaded ring has a circumferential array of multiple friction pads, which are made of elastic rubber.

[0012] Furthermore, U-shaped fixing plates are symmetrically fixed at both ends of the measuring rod, and extrusion bolts are threaded to the side walls of the U-shaped fixing plates; an elastic rubber pad is fixed at one end of the extrusion bolt located on the inner side of the U-shaped fixing plate, which is used to fix the measuring rod above the cutter shaft.

[0013] Furthermore, the number of the first clamping plate, the second clamping plate, and the circular knife corresponds to each other.

[0014] Furthermore, the first and second clamping plates are inclinedly disposed on the outer side of the top surface of the circular knife to form a protective structure.

[0015] In summary, this utility model has the following beneficial technical effects: The measuring rod, first clamp, and second clamp in this design are fixed above the cutter shaft. The scale markings on the measuring rod are aligned with the circular cutter, allowing the operator to quickly determine the installation spacing of the circular cutter. Multiple clamps are fitted onto the measuring rod. After determining the position of the circular cutter, the operator moves the clamps on both sides of the circular cutter, clamping them on both sides. A rigid fixation is achieved through the spiral compression mechanism of the external and internal threaded rings. When fixing the circular cutter later, the positioning support of the clamps prevents external forces from causing the circular cutter to slip, improving the installation accuracy of the circular cutter. At the same time, it avoids the problem of low installation efficiency caused by multiple measurement and calibration. After the circular cutter is fixed, the operator can loosen the clamps and rotate them upwards to fix them again without affecting the normal use of the circular cutter. This solution uses a circular blade and clamping plate. After the clamping plate is fixedly held on both sides of the circular blade, it tilts to cover the top side of the circular blade, isolating the operator from contact with the blade and reducing the risk of personnel installing the circular blade. In addition, when disassembling the circular blade, the operator can slide the clamping plate to move the circular blade for disassembly, further reducing the risk of scratches and improving operational safety.

[0018] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0019] Example 1: In this example, refer to Figure 1 and Figure 2As shown, specifically, a dust-free slitting machine includes a cutter shaft 1 and a circular cutter 2 fixed on the cutter shaft 1. The installation principle and specific structure of the cutter shaft 1 and the circular cutter 2 can be referred to in existing slitting machine equipment, which are common existing technologies, so they are not described in detail here. A measuring rod 3 is provided above the cutter shaft 1. U-shaped fixing plates 34 are symmetrically fixed at both ends of the measuring rod 3. The side wall of the U-shaped fixing plate 34 is threaded with a compression bolt 35. An elastic rubber pad 36 is fixed to one end of the compression bolt 35 located inside the U-shaped fixing plate 34, which is used to hold the measuring rod 36 in place. The measuring rod 3 is fixed above the cutter shaft 1. In actual operation, the U-shaped fixing plate 34 is clamped in the appropriate position of the equipment and the bolts are tightened to fix it, so that the measuring rod 3 and the cutter shaft 1 are aligned. The side wall of the measuring rod 3 is provided with scale marks 31, which are used to measure the installation spacing of the circular cutter 2. When actually installing the circular cutter 2, the operator can quickly determine the position of the circular cutter 2 and the spacing between adjacent circular cutters 2 by referring to the scale marks 31 on the measuring rod 3 that are aligned with the circular cutter 2. Compared with the traditional method of using vernier calipers to determine the cutter spacing, it is more convenient and faster, and there is no need to repeat the measurement multiple times.

[0020] Reference Figure 1 , Figure 3 and Figure 4 As shown, specifically, a first clamping plate 4 and a second clamping plate 5 are sleeved on the measuring rod 3. The first clamping plate 4 and the second clamping plate 5 clamp the two sides of the circular knife 2. The upper side wall of the first clamping plate 4 is provided with a sleeve hole 41, through which the measuring rod 3 passes, allowing the first clamping plate 4 to slide along the measuring rod 3. This facilitates clamping and fixing the circular knife 2 at different positions. The number of the first clamping plate 4, the second clamping plate 5, and the circular knife 2 corresponds to each other, achieving individual positioning and fixing of each circular knife 2, which is convenient for the operator to flexibly adjust the position of each circular knife 2. An external threaded ring 42 is fixed to the upper side wall of the first clamping plate 4. Four extrusion arc plates 43 are fixed to the side wall of the external threaded ring 42. Extrusion pads 431 are fixed to the side wall edge of the extrusion arc plates 43. The extrusion pads 431 are made of elastic rubber material to improve the extrusion friction. The extrusion arc plates 43 are located outside the measuring rod 3. An internal threaded ring 44 is fitted onto the outer side of the 43. One end of the internal threaded ring 44 is threaded to the outer side of the external threaded ring 42. The internal threaded ring 44 has multiple friction pads 442 arranged in a circumferential array. The friction pads 442 are made of elastic rubber to increase the stability of manual operation. The other end of the internal threaded ring 44 is fixed with a compression ring 441. The compression ring 441 is located on one side of the compression arc plate 43. The inner circle size of the compression ring 441 is larger than the outer circle size of the ring formed by the multiple compression arc plates 43. This allows the compression ring 441 to be driven by the internal threaded ring 44 to move on the external threaded ring 42, thereby pushing the compression arc plate 43 to press against the measuring rod 3 and locking the first clamping plate 4. One side wall of the compression arc plate 43 is inclined, which facilitates radial compression deformation by the compression ring 441. The external threaded ring 42 is located outside the sleeve hole 41. The second clamping plate 5 is symmetrically arranged with the first clamping plate 4. Specifically, using the above technical solution, when the operator installs the circular blade 2 on the cutter shaft 1, the measuring rod 3 quickly determines the installation position of the circular blade 2 and the distance between adjacent circular blades 2. Then, the operator moves the first clamping plate 4 and the second clamping plate 5, which are sleeved on the measuring rod 3, to clamp the outer side of the circular blade 2. By tightening the internal threaded ring 44 on the upper side wall of the clamping plate, the extrusion arc plate 43 can press against the measuring rod 3 to lock the position of the clamping plate. This achieves stable clamping and positioning of the circular blade 2 by the two clamping plates. When fixing the circular blade 2 later, the support and positioning of the two clamping plates prevents the circular blade 2 from slipping due to external force, thus avoiding inconsistent spacing of the circular blades 2 and affecting the cutting quality. Compared with the traditional method that requires the operator to hold the circular blade 2 with one hand and fix it with the other, it is safer and more convenient. There is no need to recalibrate the spacing of the circular blade 2 later, which is highly practical. After the circular blade 2 is fixed, the operator can loosen the clamping plates, lift them, and fix them again without affecting the normal operation of the circular blade 2.

[0021] Reference Figure 3 and Figure 5 As shown, specifically, the top and bottom surfaces of the measuring rod 3 are symmetrically provided with a first positioning groove 32 and a second positioning groove 33. The top of the first clamping plate 4 is provided with a threaded hole 45, and a positioning screw 46 is screwed into the threaded hole 45. The lower end of the positioning screw 46 extends to the inner side of the sleeve hole 41 and engages with the first positioning groove 32. After tightening the threaded ring on one side of the clamping plate to make the extrusion arc plate 43 press against the measuring rod 3 to lock the clamping plate, the operator will turn the positioning screw 46 on the top of the clamping plate so that its lower end is inserted into the inner side of the first positioning groove 32, thereby further locking the position of the clamping plate and making the clamping plate tilt downward stably, improving the positioning stability of the clamping plate for the circular knife 2.

[0022] Example 2: In this example, refer to Figure 1 and Figure 3 As shown, specifically, the first clamping plate 4 and the second clamping plate 5 are inclinedly arranged on the outer side of the top surface of the circular blade 2 to form a protective structure. The clamping plates cover the outer side of the top of the circular blade 2, so that the top of the circular blade 2 is not exposed. When the operator installs the circular blade 2, the risk of personnel being cut can be reduced. At the same time, when the circular blade 2 is subsequently disassembled, the clamping plates can be clamped on the outer side of the circular blade 2 again, so as to push the clamping plates to move and drive the circular blade 2 to be disassembled, further reducing the risk of personnel being cut and improving operational safety.

[0023] Working principle: When installing the circular blade 2 of the slitting machine, the operator first fixes the measuring rod 3 with scale marks 31 above the blade shaft 1. After the circular blade 2 is installed on the blade shaft 1, the operator can quickly determine the position and spacing of the circular blade 2 through the scale marks 31. Then, the operator slides the clamping plates sleeved on the measuring rod 3 so that the clamping plates clamp the two sides of the circular blade 2. By turning the threaded ring on one side of the clamping plate, the extrusion ring 441 pushes the extrusion arc plate 43 to deform the production line, thereby tightening and locking the clamping plate on the measuring rod 3. By fixing the clamping plates on both sides, the circular blade 2 can be stably clamped and fixed in the designated position. When fixing the circular blade 2 later, it is possible to avoid the circular blade 2 slipping under force, improve the accuracy of the spacing of the circular blade 2, and at the same time, the clamping plates reduce the risk of personnel being cut by shielding. After the circular cutter 2 is installed, the operator loosens the threaded ring so that the clamp can rotate on the measuring rod 3. After rotating the clamp upward, the operator screws the positioning screw 46 into the position of the second positioning groove 33 to fix the clamp and prevent it from interfering with the normal use of the circular cutter 2. When disassembling the circular cutter 2, the operator also rotates the clamp to both sides of the circular cutter 2. At this time, it is not necessary to fix the clamp. The operator can simply push the clamp to move and disassemble the circular cutter 2, which further avoids scratching personnel and improves operational safety.
