A slitting machine knife holder with width adjustment function

Abstract

This application relates to the field of slitting machine technology, and more particularly to a slitting machine blade holder with width adjustment function. To solve the problem of inconvenient fine-tuning of the slitting blade position, which severely affects the adjustment speed of the slitting blade, the holder includes a rotating rod. A positioning component is provided on the outside of the rotating rod. A slitting component is sleeved on the outer surface of the rotating rod, and an adjustment component is sleeved on the outer surface of the rotating rod. The control end of the adjustment component is slidably installed against the inner wall of the positioning component. This application utilizes a threaded rod and a threaded hole to allow a collar to release its limit, enabling the collar to drive the slitting component and the adjustment component for position adjustment. The threaded adjustment rod and the threaded adjustment hole cooperate to push an arc-shaped plate to move, thereby allowing the arc-shaped plate to engage with an arc-shaped block and an arc-shaped groove, enabling fine-tuning of the connecting ring. This, in turn, allows the connecting ring to drive fine-tuning of the slitting blade, improving the efficiency of slitting blade width adjustment.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a slitting machine blade holder with width adjustment function, including a rotating rod 1, a positioning component 2 on the outside of the rotating rod 1, a slitting component 3 on the outer surface of the rotating rod 1, and an adjustment component 4 on the outer surface of the rotating rod 1. The control end of the adjustment component 4 is slidably installed with the inner wall of the positioning component 2.

[0024] Please see Figure 2The positioning component 2 includes a set of collars 201 sleeved on the outer surface of the rotating rod 1. Each collar 201 has a threaded hole 202 on its bottom surface. Each threaded hole 202 has a threaded rod 203 threadedly connected to its inner wall. Through the cooperation of the threaded rod 203 and the threaded hole 202, the collar 201 can be positioned outside the rotating rod 1, thereby enabling the rotating rod 1 to move.

[0025] Please see Figure 3 and Figure 4 The adjusting component 4 includes a set of connecting blocks 401 mounted on the upper surface of a set of positioning components 2. A support block 402 is fixedly mounted on the right side of each connecting block 401. A support plate 403 is fixedly mounted on the right end of each support block 402. A threaded adjusting hole 405 is opened on the right side of each support plate 403. A threaded adjusting rod 404 is threadedly connected to the inner wall of each threaded adjusting hole 405. An arc-shaped plate 406 is rotatably mounted on the left end of each threaded adjusting rod 404 via a bearing. An arc-shaped groove 407 is opened on the right side of each collar 201. Each arc-shaped groove 407 has an arc-shaped block 408 slidably installed on its inner wall. The right ends of the two sets of arc-shaped blocks 408 are fixedly installed on the left side of an arc-shaped plate 406. The support plate 403 can be supported by the connecting block 401 and the support block 402, so that the support plate 403 can remain stable. The arc-shaped plate 406 can be moved by the threaded connection of the threaded adjusting rod 404 and the threaded adjusting hole 405, thereby enabling the arc-shaped plate 406 to push the arc-shaped block 408 to move, and the arc-shaped block 408 to push the connecting ring 301 to move.

[0026] Please see Figure 3 The slitting assembly 3 includes a set of connecting rings 301 sleeved on the outer surface of the rotating rod 1. The left ends of the two sets of arc blocks 408 are respectively fixedly installed on the right side of the connecting rings 301. An installation ring 302 is fixedly installed on the left side of each connecting ring 301. A slitting blade 304 is sleeved on the outer surface of each connecting ring 301. A set of installation holes 303 are opened on the right side of each installation ring 302 and the right side of the slitting blade 304. The slitting blade 304 can be disassembled and installed by the installation rings 302 and the installation holes 303, and the slitting blade 304 can cut the workpiece.

[0027] Please see Figure 2 Support rods 101 are fixedly installed at both ends of the rotating rod 1. A first guide groove 102 is provided on the bottom surface of the rotating rod 1. A second guide groove 204 is provided on the inner wall of each collar 201. The first guide groove 102 and the second guide groove 204 are adapted to each other. Through the cooperation of the first guide groove 102 and the second guide groove 204, the collar 201 can be limited so that the collar 201 can be kept in the limited position and prevent the collar 201 from rotating around the rotating rod 1.

[0028] Please see Figure 3 The inner wall of the connecting ring 301 is provided with a third guide groove 305, which is adapted to the first guide groove 102. The cooperation between the third guide groove 305 and the first guide groove 102 can prevent the connecting ring 301 from rotating.

[0029] Please see Figure 4 Each collar 201 has a limiting hole 5 on its right side. A limiting rod 501 is slidably installed on the inner wall of each limiting hole 5. The right ends of the two sets of limiting rods 501 are fixedly installed on the left side of a set of arc plates 406. The arc plates 406 can be guided by the limiting holes 5 and the limiting rods 501, so that the arc plates 406 can move.

[0030] The implementation principle of a slitting machine blade holder with width adjustment function according to an embodiment of this application is as follows: When adjustment is required, the threaded rod 203 is rotated, causing it to slide inside the threaded hole 202, thereby moving the threaded rod 203 downward and releasing the positioning of the collar 201. Then, the collar 201 is pushed, causing it to move the connecting ring 301, the mounting ring 302, and the slitting blade 304, thus adjusting the position of the slitting blade 304. After adjustment, the width of the slitting blade 304 is measured. If there is a difference in width, the threaded adjusting rod 404 is rotated, causing it to move through the threaded adjusting hole 405. The threaded adjusting rod 404 controls the movement of the arc plate 406, which in turn moves the arc block 408, causing the arc block 408 to move the slitting blade 304, thus fine-tuning the position of the slitting blade 304 and improving the efficiency of position adjustment.
