Description

Technical Field

[0001] The utility model relates to the technical field of machine tool equipment, and particularly relates to a tool with dynamically adjustable clearance. Background Technique

[0002] Automated slitting machines are generally applicable to the slitting of various rolled materials such as BOPP, CPP, CPE, PVC, aluminum foil, paper, etc. During the production process, the materials are trimmed and slit according to different needs. Currently, it is rather troublesome to adjust the distance of the tools on the automated slitting machine. Since the mounting holes on the main shaft are generally fixed, when adjusting the distance of the tool, due to the non-fixed length of the tool adjustment, the mounting holes cannot be opened according to the hole pitch required by the user. When adjusting the clearance of the tool, additional mounting holes need to be opened, which not only affects the work efficiency but also the service life of the main shaft. Therefore, a tool with dynamically adjustable clearance is needed.

[0003] The prior art patent document with the technical publication number CN212945473U provides a tool capable of adjusting the blade clearance, including a tool handle and a tool head at the front end of the tool handle. The upper tool seat and the lower tool seat are connected by a connecting bridge, and a U-shaped bridge structure is formed among the upper tool seat, the lower tool seat, and the connecting bridge. An upper blade and a lower blade are respectively installed at the front end of the U-shaped bridge opening of the upper tool seat and the lower tool seat. There is a machining gap between the upper blade and the lower blade. The front end of the lower tool seat of the lower blade is at the front end of the elastic adjustment section of the U-shaped bridge. A clearance fine adjustment and locking mechanism is arranged between the upper tool seat and the lower tool seat. This clearance fine adjustment and locking mechanism is at the position between the connecting bridge of the U-shaped bridge and the blade. The clearance between the lower tool seat and the front end of the upper tool seat can be adjusted through the clearance fine adjustment and locking mechanism. By operating the clearance fine adjustment and locking mechanism between the two tool seats, the lower blade can be pushed away from or tightened against the upper tool seat, thus facilitating the adjustment of the interval between the upper and lower blades without a cumbersome disassembly and adjustment process, and the production and processing efficiency is high. However, when the technology of CN212945473U is operated, it cannot effectively improve the flexibility of the device to adjust the blade position, at the same time, it cannot effectively improve the protection effect of the device during use, and it cannot improve the convenience of device installation. Therefore, a tool with dynamically adjustable clearance is urgently needed. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide a tool with dynamically adjustable clearance to solve the problems that the existing tools cannot effectively improve the flexibility of the device to adjust the blade position, at the same time, cannot effectively improve the protection effect of the device during use, and cannot improve the convenience of device installation.

One end of the working shaft 5 is installed with a cutter limiting block 7. One end of the cutter limiting block 7 is installed with a plate setting screw 8. One end of the plate setting screw 8 is installed with a fixing plate bolt 9. One end of the mounting frame 1 is provided with a slideway 10. The clamping shaft block 4 forms a sliding structure with the mounting frame 1 through the chute 2, and the clamping shaft block 4 is snap-connected with the working shaft 5 through the downward pressure spring 3. The cutting blade 6 forms a rotating structure with the mounting frame 1 through the working shaft 5, and the inner end surface of the cutter limiting block 7 is closely attached to the outer end surface of the cutting blade 6. The cutter limiting block 7 forms a sliding structure with the mounting frame 1 through the slideway 10, and the fixing plate bolt 9 is threadedly connected with the cutter limiting block 7 through the plate setting screw 8. Align the center hole position of the cutting blade 6 with the center of the lower opening of the cutter limiting block 7 and place it in the middle. Then pass the working shaft 5 through the lower opening of the mounting frame 1 and simultaneously through the center hole position of the cutting blade 6 until the downward pressure spring 3 presses down the clamping shaft block 4 in the chute 2 to engage with one end of the working shaft 5, thereby restricting the positions of the cutting blade 6 and the working shaft 5 on the mounting frame 1. And the fixing plate bolt 9 can be operated to rotate on the plate setting screw 8 according to the cutting requirements, so as to adjust the position of the cutting blade 6 under the cutter limiting block 7 on the working shaft 5. When the two fixing plate bolts 9 are simultaneously rotated towards the cutter limiting block 7 in the middle, the position of the cutting blade 6 can be fixed, improving the flexibility of the device to adjust the blade position.

[0025] Please refer to Figures 1-4 , A tool with dynamically adjustable clearance. One end of the cutter limiting block 7 is provided with a card slot 11. One end of the card slot 11 is installed with a protective cover 12. The protective cover 12 is snap-connected with the cutter limiting block 7 through the card slot 11, and the protective cover 12 is symmetrically arranged with respect to the central axis of the cutter limiting block 7. Install a motor on the mounting frame 1 on one side of the working shaft 5, which can drive the cutting blade 6 on the working shaft 5 to rotate at high speed for cutting work. And the protective cover 12 can be symmetrically inserted into the card slots 11 opened on both sides of the cutter limiting block 7, so as to cover the non-working position of the cutting blade 6, prevent the danger of the cutting blade 6 working, and improve the protection effect of the device during use.
