Description

Technical Field

[0002] For example, the Chinese patent with announcement number CN216266434U discloses a slitting mechanism for a slitting machine, which passes the strip through the lower surface of the sleeve and then through the surface of the roller until the strip is tightened. Then, by rotating the round rod, the round rod drives the limit plate to rotate, the limit plate drives the clamping block to move, the clamping block drives the tool holder to move, and the tool holder drives the blade to move so that the blade is close to the surface of the strip. The round rod is then fixed by a third screw. Then, according to customer requirements, the slider is slid inside the slide groove to adjust the position of the clamping block, thereby adjusting the position of the tool. Then, it is locked by the first screw. Strips of different widths and strips are cut according to the tools in different positions, making the use of the strip wider and more convenient.

[0003] When it is necessary to cut materials into different widths, the existing technology requires removing excess blades or reinstalling a corresponding number of blades according to the number of strips to be cut. Both disassembly and installation are cumbersome, which reduces the efficiency of cutting and stripping. In addition, when facing thicker materials such as leather fabrics, rubber belts, etc., the blades will become blunt after long-term use, which may cause burrs on the cutting edge, thereby affecting the cutting effect.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] Based on the existing existing technology, when adjusting the spacing of the cutting material, the blade needs to be disassembled, which is cumbersome to operate, and the blade becomes blunt after long-term use, affecting the cutting effect. This embodiment provides a slitting mechanism for a slitting machine, please refer to Figure 1-Figure 4 The embodiment provides a slitting mechanism for a slitting machine, which can improve cutting accuracy and maintain blade sharpness. The slitting mechanism for a slitting machine includes a cutting frame 2 mounted on a slitting machine 1. The cutting frame 2 is equipped with a spacing adjustment mechanism 3 that adjusts according to the material cutting size. The connecting end of the spacing adjustment mechanism 3 is equipped with a slitting mechanism 4 that cuts the material into strips. The spacing of the slitting mechanisms 4 is adjusted according to the required cutting size by the spacing adjustment mechanism 3. The electric push rod 304 rotates the slitting mechanisms 4 downward by a corresponding number to cut the material into strips. The replacement component 405 in the slitting mechanism 4 is used to quickly replace damaged blades. The provision of the grinding component 406 facilitates grinding of blunt blades to improve blade sharpness.

[0025] Since the existing technology requires the removal of redundant blades or the installation of corresponding blades according to the number of strips cut to the material, the operation is relatively cumbersome. Therefore, a distance adjustment mechanism 3 without the need to remove the blades is proposed. The distance adjustment mechanism 3 includes distance adjustment slots 301 provided on both sides of the cutting frame 2, and a mounting seat 302 is slidably connected to the cutting frame 2. Threaded holes are provided on both sides of the mounting seat 302, and the internal threads of the threaded holes are connected to fastening bolts 303 that pass through the distance adjustment slots 301. An electric The push rod 304 is driven, and the free end of the electric push rod 304 passes through the cutting frame 2 and is connected to the slitting mechanism 4. According to the actual number of strips to be cut and the width of the material, the mounting seat 302 is pulled to move to the specified position on the cutting frame 2, and then the mounting seat 302 is fixed to the cutting frame 2 by tightening the bolts 303. Then, the electric push rod 304 is started to push the cutting wheel 403 at its bottom to move down to contact with the material and cut the material, and the excess cutting wheel 403 can be maintained at a certain height without being disassembled.

[0026] When facing thicker fabrics such as leather, the device is also provided with a slitting mechanism 4, which includes a mounting plate 401 connected to the free end of the electric push rod 304, and a rotating shaft 402 is rotatably connected to the mounting plate 401, and a cutting wheel 403 is installed on the rotating shaft 402. A driving motor 404 for driving the rotating shaft 402 to rotate is installed on one side of the mounting plate 401, and a replacement component 405 for disassembling and replacing the cutting wheel 403 is provided on the rotating shaft 402. A frosting component 406 acting on the cutting wheel 403 is provided on the free end of the electric push rod 304. Starting the driving motor 404 drives the rotating shaft 402 to rotate on the mounting plate 401, thereby driving the cutting wheel 403 on the rotating shaft 402 to rotate, and performing rotary cutting on the material, thereby improving the cutting efficiency and accuracy.

[0027] The cutting wheel 403 needs to be replaced after long-term use, so the device is also provided with a replacement component 405. The replacement component 405 includes a washer 4051 sleeved on the rotating shaft 402, and the two washers 4051 are respectively located on both sides of the cutting wheel 403. The rotating shaft 402 is threadedly connected with a locking nut 4052 that fixes the cutting wheel 403 thereon. When the cutting wheel 403 needs to be replaced, the locking nut 4052 is unscrewed from the external thread at the end of the rotating shaft 402, and then the outer washer 4051 is removed. After replacing the new cutting wheel 403, it can be installed in sequence, which is more convenient and quick to install.

[0028] Example 2

[0029] On the basis of Example 1, Figure 1-Figure 4As shown, based on the problem that the existing blade becomes blunt after long-term use, which may cause burrs on the cutting edge, thereby affecting the cutting effect, the device is also provided with a grinding component 406, which includes a sliding sleeve 4061 installed on one side of the free end of the electric push rod 304, and an electromagnet 4062 is installed on the top wall of the sliding sleeve 4061, and a tension spring 4063 is installed at the bottom of the electromagnet 4062, and a magnetic block 4064 is installed at the bottom of the tension spring 4063, and a sliding rod 4065 that slides up and down in the sliding sleeve 4061 is installed at the bottom of the magnetic block 4064, and a shell 4066 is installed at the bottom of the sliding rod 4065, and a grinding block 4067 is installed on the inner wall of the shell 4066.

[0030] The outer side of the cutting wheel 403 is a cutting edge 407, and a grinding groove is formed on the grinding block 4067 to fit the cutting edge 407. The inner diameter of the bottom outlet of the sliding sleeve 4061 is smaller than the diameter of the magnet 4064 and is the same as the diameter of the slide rod 4065. When the cutting wheel 403 needs to be sharpened, the electromagnet 4062 is energized, generating a repulsive force between the electromagnet 4062 and the magnet 4064, pushing the magnet 4064 and the slide rod 4065 downward until the magnet 4064 moves to the bottom of the sliding sleeve 4061. At this time, the housing 4066 at the bottom of the slide rod 4065 moves downward onto the cutting wheel 403, and the grinding groove on the grinding block 4067 inside the housing 4066 contacts the cutting edge 407 of the cutting wheel 403, thereby grinding the cutting edge 407 to maintain its sharpness.
