Description

Technical Field

[0001] This application relates to the field of slitting machine technology, and in particular to a cutting shaft clamping device for a slitting machine. Background Technology

[0002] Dual-axis slitting machines are generally suitable for cutting and processing items such as paper, film, gold and silver foil, aluminum foil, copper foil, and magnetic tape. They have high processing efficiency and a wide range of applications.

[0003] Currently, most slitting machine cutting shaft clamping devices on the market use bolt fastening, that is, the cutting blade (including the mounting shaft and the ring blade) is directly fixed to the frame with bolts. Although this method ensures the stability of the cutting shaft to a certain extent, it has many inconveniences in the installation and disassembly process. Since bolt tightening requires a certain torque and time, it not only increases the difficulty of operation but also reduces work efficiency. In addition, frequent bolt tightening operations may also cause the bolts to loosen or be damaged, affecting the clamping effect of the cutting shaft.

[0004] Therefore, this application provides a cutting shaft clamping device for a slitting machine. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a cutting shaft clamping device for a slitting machine, overcoming the deficiencies of the prior art. It aims to solve the problem that most cutting shaft clamping devices on the market currently use bolt fastening, where the cutting blade (including the mounting shaft and the ring blade) is directly fixed to the frame with bolts. While this method ensures the stability of the cutting shaft to a certain extent, it presents many inconveniences during installation and disassembly. Because bolt tightening requires a certain torque and time, it not only increases the difficulty of operation but also reduces work efficiency. Furthermore, frequent bolt tightening operations may lead to bolt loosening or damage, affecting the clamping effect of the cutting shaft.

[0006] To achieve the above objectives, this application provides the following technical solution: a cutting shaft clamping device for a slitting machine, comprising a frame, two sets of fixed seats symmetrically installed inside the frame, a cutting shaft rotatably connected between the two sets of fixed seats, a plurality of annular blades mounted on the outer surface of the cutting shaft, mounting portions mounted at both ends of the cutting shaft, clamping mechanisms mounted on the opposite surfaces of the two sets of fixed seats, the clamping mechanism comprising a positioning ring, the positioning ring being mounted on the side of the fixed seat near the mounting portion and adapted to the mounting portion, a cutting inlet opening on one side of the positioning ring, a clamping block mounted on the top of the positioning ring, a first bolt threadedly connected to the connection between the clamping block and the positioning ring, a connecting groove matching the first bolt being opened on the top of the positioning ring, and a guide rail mounted on the bottom of the positioning ring.

[0007] By adopting the above technical solution, after connecting the ring cutter to the cutting shaft, it is installed on the frame. At this time, simply place the two sets of mounting parts on the side of the two sets of guide rails that are far apart, move them towards the positioning ring, insert them from the inlet, and then adjust the clamping block to the appropriate position. Finally, connect the first bolt to the connecting groove of the positioning ring to complete the fastening. When disassembling, simply loosen the first bolt and move the cutting shaft to easily remove it from between the two sets of clamping mechanisms. The two sets of clamping mechanisms not only simplify the installation and disassembly process of the cutting shaft, but also improve work efficiency and clamping stability, and have broad market application prospects.

[0008] As a preferred technical solution of this application, a pressure sensor is fixedly installed on the side of the clamping block near the positioning ring, and a warning light is fixedly installed on the outer wall of the guide rail. The pressure sensor is electrically connected to the warning light.

[0009] By adopting the above technical solution, the clamping force of the clamping block on the mounting part is monitored in real time by a pressure sensor. The pressure sensor is electrically connected to a warning light. When the pressure sensor detects that the clamping force on the mounting part reaches a preset value, the warning light can light up to remind the operator, thereby enhancing the clamping effect of the clamping mechanism.

[0010] As a preferred embodiment of this application, a shock-absorbing pad is fixedly installed on the side wall of the clamping block, and the shock-absorbing pad is located on the outer periphery of the pressure sensor.

[0011] By adopting the above technical solution, the vibration generated during the cutting process is absorbed by the shock-absorbing pad, which is specifically a rubber pad. This improves the stability of the clamping block in clamping the mounting part, thereby enhancing the clamping effect of the clamping mechanism.

[0012] As a preferred technical solution of this application, the connection between the positioning ring and the fixed seat is threaded with a second bolt, and the connection between the guide rail and the positioning ring is threaded with a third bolt.

[0013] By adopting the above technical solution, the positioning ring and guide rail can be easily replaced using the second and third bolts, thus allowing the positioning ring and guide rail to be replaced as needed, improving practicality during use.

[0014] As a preferred technical solution of this application, a support frame is installed at the bottom of the guide rail, and a fourth bolt is threadedly connected to the connection between the support frame and the guide rail.

[0015] By adopting the above technical solution, the support frame is connected to the guide rail by the fourth bolt, so that the support frame supports the guide rail and enhances the stability of the guide rail after installation.

[0016] As a preferred technical solution of this application, the inner wall of the positioning ring is fixedly connected with a wear-resistant layer.

[0017] By adopting the above technical solution, the wear-resistant layer helps to enhance the wear resistance of the positioning ring and extend its service life.

[0018] As a preferred technical solution of this application, a rotating sleeve is fixedly installed on the top of the first bolt.

[0019] By adopting the above technical solution, the rotating sleeve allows operators to manually tighten or loosen the first bolt, reducing the use of tools and improving the convenience of adjusting the first bolt.

[0020] As a preferred technical solution of this application, the corners of the positioning ring are provided with rounded chamfers on both the upper and lower sides of the inlet.

[0021] By adopting the above technical solution, the smoothness of the positioning ring is improved by rounding the chamfer, which helps to improve the protection of workers during the installation process.

[0022] The beneficial effects of this application are:

[0023] 1. After connecting the ring cutter to the cutting shaft, install it onto the frame. Simply place the two sets of mounting parts on the side of the two sets of guide rails that are far apart, move them towards the positioning ring, insert them from the inlet, and then adjust the clamping blocks to the appropriate position. Finally, connect the first bolt to the connecting groove of the positioning ring to complete the fastening. To disassemble, simply loosen the first bolt and move the cutting shaft to easily remove it from between the two sets of clamping mechanisms. The two sets of clamping mechanisms not only simplify the installation and disassembly process of the cutting shaft, but also improve work efficiency and clamping stability, and have broad market application prospects.

[0024] 2. The clamping force of the clamping block on the mounting part is monitored in real time by a pressure sensor. The pressure sensor is electrically connected to a warning light. When the pressure sensor detects that the clamping force on the mounting part reaches a preset value, the warning light will light up to remind the operator, thereby enhancing the clamping effect of the clamping mechanism.

A cutting shaft 3 is rotatably connected between the two sets of fixed seats 2. Several sets of annular blades 5 are installed on the outer surface of the cutting shaft 3. Mounting parts 4 are installed at both ends of the cutting shaft 3. Clamping mechanisms 6 are installed on the opposite sides of the two sets of fixed seats 2. The clamping mechanism 6 includes a positioning ring 601. The positioning ring 601 is installed on the side of the fixed seat 2 near the mounting part 4 and is adapted to the mounting part 4. A cutting inlet 602 is opened on one side of the positioning ring 601. A clamping block 603 is installed on the top of the positioning ring 601. A first bolt 604 is threadedly connected to the connection between the clamping block 603 and the positioning ring 601. A connecting groove 605 matching the first bolt 604 is opened on the top of the positioning ring 601. A guide rail 7 is installed on the bottom of the positioning ring 601. A shock-absorbing pad 9 is fixedly installed on the side wall of the clamping block 603. The shock-absorbing pad 9 is located on the outer periphery of the pressure sensor 8.

[0032] After the ring cutter 5 is connected to the cutting shaft 3, it is installed on the frame 1. At this time, simply place the two sets of mounting parts 4 on the opposite sides of the two sets of guide rails 7, move them toward the positioning ring 601, insert them into the inlet 602, and then adjust the clamping block 603 to the appropriate position. Finally, connect the first bolt 604 to the connecting groove 605 of the positioning ring 601 to complete the fastening. When disassembling, simply loosen the first bolt 604 and move the cutting shaft 3 to easily remove the cutting shaft 3 from between the two sets of clamping mechanisms 6. The two sets of clamping mechanisms 6 not only simplify the installation and disassembly process of the cutting shaft 3, but also improve work efficiency and clamping stability, and have broad market application prospects. The vibration generated during the cutting process is absorbed by the shock-absorbing pad 9, which is a rubber pad, which improves the stability of the clamping block 603 in clamping the mounting part 4, thereby enhancing the clamping effect of the clamping mechanism 6.

[0033] Reference Figure 2-4 A pressure sensor 8 is fixedly installed on the side of the clamping block 603 near the positioning ring 601. A warning light 10 is fixedly installed on the outer wall of the guide rail 7. The pressure sensor 8 is electrically connected to the warning light 10. A second bolt 11 is threadedly connected to the connection between the positioning ring 601 and the fixed seat 2. A third bolt 12 is threadedly connected to the connection between the guide rail 7 and the positioning ring 601.

[0034] The clamping force of the clamping block 603 on the mounting part 4 is monitored in real time by the pressure sensor 8. The pressure sensor 8 is electrically connected to the warning light 10. When the pressure sensor 8 detects that the clamping force of the clamping block 603 on the mounting part 4 reaches the preset value, the warning light 10 can light up to remind the operator, thereby enhancing the clamping effect of the clamping mechanism 6. The second bolt 11 and the third bolt 12 facilitate the replacement of the positioning ring 601 and the guide rail 7, so that the positioning ring 601 and the guide rail 7 can be replaced as needed, improving the practicality during use.

[0035] Reference Figure 2-4 A support frame 13 is installed at the bottom of the guide rail 7, and a fourth bolt 14 is threadedly connected to the connection between the support frame 13 and the guide rail 7. A rotating sleeve 16 is fixedly installed on the top of the first bolt 604. The support frame 13 is connected to the guide rail 7 through the fourth bolt 14, so that the support frame 13 supports the guide rail 7 and enhances the stability of the guide rail 7 after installation. The rotating sleeve 16 makes it easy for the operator to manually tighten or loosen the first bolt 604, reducing the use of tools and improving the convenience of adjusting the first bolt 604.

[0036] Reference Figure 2-4The inner wall of the positioning ring 601 is fixedly connected with a wear-resistant layer 15; the corners of the positioning ring 601 are provided with rounded chamfers on both the upper and lower sides of the inlet 602; the wear-resistant layer 15 helps to enhance the wear resistance of the positioning ring 601 and extend its service life; the rounded chamfers improve the smoothness of the positioning ring 601, which helps to improve the protection of workers during installation.

[0037] Working principle: After the ring cutter 5 is connected to the cutting shaft 3, it is installed on the frame 1. At this time, simply place the two sets of mounting parts 4 on the side of the two sets of guide rails 7 that are far apart, move them towards the positioning ring 601, insert them from the inlet 602, and then adjust the clamping block 603 to the appropriate position. Then, connect the first bolt 604 to the connecting groove 605 of the positioning ring 601 to complete the fastening. When disassembling, simply loosen the first bolt 604 and move the cutting shaft 3 to easily remove the cutting shaft 3 from the two sets of clamping mechanisms 6. The two sets of clamping mechanisms 6 not only simplify the installation and disassembly process of the cutting shaft 3, but also improve work efficiency and clamping stability, and have broad market application prospects. The clamping force of the clamping block 603 on the mounting part 4 is monitored in real time by the pressure sensor 8. The pressure sensor 8 is electrically connected to the warning light 10. When the pressure sensor 8 detects that the clamping force of the pressure sensor 8 on the mounting part 4 reaches the preset value, the warning light 10 can light up to remind the operator, thereby enhancing the clamping effect of the clamping mechanism 6.

[0038] The vibration generated during the cutting process is absorbed by the shock-absorbing pad 9, which is a rubber pad. This improves the stability of the clamping block 603 in clamping the mounting part 4, thereby enhancing the clamping effect of the clamping mechanism 6. The second bolt 11 and the third bolt 12 facilitate the replacement of the positioning ring 601 and the guide rail 7, so that the positioning ring 601 and the guide rail 7 can be replaced as needed, improving the practicality during use.

[0039] Meanwhile, the support frame 13 is connected to the guide rail 7 by the fourth bolt 14, so that the support frame 13 supports the guide rail 7 and enhances the stability of the guide rail 7 after installation; the wear-resistant layer 15 helps to enhance the wear resistance of the positioning ring 601 and extend the service life of the positioning ring 601.
