A slitting machine tool holder mechanism Technical Field

[0001] This utility model relates to the field of slitting machine technology, and specifically to a slitting machine tool holder mechanism. Background Technology

[0002] A slitting machine is a device for longitudinally cutting wide rolls of material. The knife holder is a component on the slitting machine that needs to be frequently disassembled and reassembled. The slitting machine knife holder usually consists of an upper knife shaft and a lower knife shaft that are fixed parallel to each other on the knife shaft holder.

[0003] Currently, slitting machine tool holders lack auxiliary heat dissipation mechanisms. During slitting machine operation, the friction between the rotating tool and the workpiece generates a significant amount of heat. However, the lack of auxiliary heat dissipation can easily lead to tool deformation, affecting processing quality and accelerating tool wear. Therefore, a slitting machine tool holder mechanism is proposed to add an auxiliary heat dissipation mechanism around the tool during tool holder use, improving tool performance, slowing down wear, enhancing efficiency, and extending tool life. Summary of the Invention

The main shaft is rotatably connected inside the tool holder through a rotating shaft. The tool assembly is sleeved around the main shaft. Mounting brackets corresponding to the main shaft are provided at the top and bottom of the tool holder. A heat dissipation component is provided at the bottom of the mounting bracket.

[0018] Specifically, the top and bottom of the tool holder are both connected to the cylinder by bolts, and the output end of the cylinder is connected to the mounting bracket by bolts.

[0019] By adopting the above technical solution, the displacement of the heat dissipation component can be driven.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To improve the quality of tool use, slow down the wear rate, and thus improve the performance and extend the service life of the tools, as shown in Figures 1-3, the slitting machine tool holder mechanism of this utility model includes a tool holder 1, a main shaft 2, and a tool assembly 3. The main shaft 2 is rotatably connected to the tool holder 1 through a rotating shaft. The tool assembly 3 is sleeved around the main shaft 2. Mounting brackets 4 corresponding to the main shaft 2 are provided at the top and bottom of the tool holder 1. A heat dissipation component 5 is provided at the bottom of the mounting bracket 4.

[0033] The tool assembly 3 includes a sliding seat 301, and the outer periphery of the sliding seat 301 is connected to the blade 302 by bolts. Heat-conducting plates 303 are bolted to both sides of the outer periphery of the sliding seat 301 on both sides of the blade 302. The heat dissipation assembly 5 includes a U-shaped frame 501, and iron balls 502 are rolledly connected to both sides of the U-shaped frame 501 through reserved ball grooves. The outer side of the tool holder 1 is bolted to the exhaust fan 6.

[0034] During use, an auxiliary heat dissipation mechanism can be added around the tool by means of heat conduction plate 303, U-shaped frame 501, iron ball 502 and exhaust fan 6. By using contact heat conduction and accelerating air circulation, the blade 302 is subjected to auxiliary heat dissipation treatment, thereby improving the tool's performance and machining quality, and also helping to extend the service life of the blade 302.

[0035] To improve the flexibility of the tool assembly, as exemplarily shown in FIG5, the present invention further includes a slide seat 301 comprising a protrusion 304, a connecting rod 305 sleeved on the inner side of the protrusion 304, a positioning screw 306 threadedly connected to the outer surface of the slide seat 301 through a reserved threaded hole, and a return spring 307 sleeved inside the protrusion 304 on the periphery of the connecting rod 305.

[0036] In use, the tool assembly 3 can be adjusted in terms of its position and spacing by means of the protrusion 304 and the insertion rod 305, thereby adapting to different processing requirements. The positioning screw 306 and the return spring 307 facilitate the control and adjustment of the position of the insertion rod 305.

[0037] For example, as shown in FIG2, the present invention further includes a ventilation hole 503 on the inner surface of the U-shaped frame 501, and a connection hole 504 corresponding to the ventilation hole 503 on both sides of the U-shaped frame 501, and the air inlet end of the exhaust fan 6 is connected to the connection hole 504 through a flexible hose.

[0038] During use, the exhaust fan 6 can be connected through the ventilation hole 503 and the connection hole 504 to draw air from the outside of the blade for auxiliary heat dissipation.

[0039] As exemplarily shown in FIG5, the present invention further includes a groove 201 formed on the surface of the main shaft 2, and an insertion hole 202 formed on the inner side of the groove 201.

[0040] In use, the groove 201 facilitates the sliding connection with the protrusion 302 of the sliding seat 301, while allowing the insertion rod 305 to be inserted into the corresponding insertion hole 202 to complete the quick positioning and fixing process.

[0041] For example, as shown in FIG3, the present invention further includes that the mounting bracket 4 includes a slide groove 401, and the sliding seat 301 is slidably connected to the slide groove 401 through an outer slider, and the surface of the slide groove 401 is provided with a fastening screw 402 corresponding to the slider of the sliding seat 301 through a reserved opening.

[0042] During use, the position of the heat dissipation component 5 can be easily adjusted according to the position of the tool assembly 3 via the slide groove 401 and the fastening screw 402.

[0043] For example, as shown in FIG6, the present invention further includes a main shaft 2 including a transmission shaft 203, a transmission gear 204 being bolted to the periphery of the transmission shaft 203, a drive motor 7 being bolted to one side of the tool holder 1, and the drive motor 7 being connected to the other end of the main shaft 2 via a drive shaft.

[0044] In use, the drive motor 7 and the transmission gear 204 can drive the main shaft 2 to rotate relative to each other to perform slitting operations.

[0045] For example, as shown in FIG1, the present invention further includes that the top and bottom of the tool holder 1 are both connected to the cylinder 8 by bolts, and the output end of the cylinder 8 is connected to the mounting bracket 4 by bolts.

[0046] During use, the cylinder 8 facilitates the displacement of the mounting bracket 4, thereby adjusting the position of the heat dissipation component 5.

[0047] When using this utility model, the operator first pushes the sliding seat 301 to slide around the spindle 2 according to the actual needs, adjusts the spacing and position of the blades 302, and then turns the positioning screw 306 to push the insert rod 305 out and insert it into the corresponding groove 201 and insertion hole 202 to complete the limiting and fixing operation of the tool assembly 3, thereby adapting to different tool holder usage needs and increasing the flexibility of use.

[0048] During use, the drive motor 7 is manually activated to drive the spindle 2 to rotate. Through the meshing connection of the transmission gear 204, the two sets of tool assemblies 3 rotate relative to each other. The cylinder 8 can also be manually activated to drive the mounting bracket 4 to move towards the corresponding tool assembly 3, so that the blade 302 and the heat-conducting plate 303 enter the U-shaped frame 501. The heat-conducting plate 303 rolls in contact with the iron ball 502, which can assist in heat dissipation. At the same time, the exhaust fan 6 is manually activated to draw air from the outside of the blade 302 through the ventilation hole 503 and the connection hole 504, which can also assist in heat dissipation. This improves the performance of the tool assembly 3 during use, avoids overheating due to friction affecting the processing quality, and helps to extend the service life of the blade 302. The structure is simple and easy to operate, making it more reasonable and convenient to use.
