Description

Technical Field

[0001] This utility model relates to the field of cutting and processing technology, and in particular to a tool spacing adjustment mechanism. Background Technology

[0002] In the field of paper cutting, especially in batch cutting of multi-size paper, the precise control of the blade spacing directly affects the flatness of the cutting edge, the consistency of dimensions, and the efficiency of the operation.

[0003] In existing technologies, traditional paper cutting blade spacing adjustment mechanisms have limitations. Most mechanisms adopt a single-blade independent adjustment mode, which requires manual adjustment of the positioning components one by one. This operation is cumbersome and time-consuming, and it is difficult to meet the needs of frequent specification switching in batch operations. At the same time, due to the lack of a symmetrical linkage structure, the spacing adjustment of multiple blades is prone to deviation, resulting in poor consistency of paper size after cutting and increasing the workload of subsequent finishing processes. In order to address the above problems, there is an urgent need for a blade spacing adjustment mechanism to overcome the limitations of existing technologies in the field of paper cutting.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Reference Figures 1 to 3 As shown, this utility model provides a technical solution: a tool spacing adjustment mechanism, including a grip 1 and an adjusting block 11. One end of the grip 1 is rotatably connected to a mounting base 2. A bearing plate 5 is fixedly connected to one side of the mounting base 2. The surface of the bearing plate 5 is provided with scale lines 9, and both ends of the bearing plate 5 are fixedly connected to side plates 6. A bidirectional lead screw 7 is rotatably connected to the surface of the side plates 6. An adjusting hole 12 is formed on the surface of the adjusting block 11, and the inner wall of the adjusting hole 12 is threadedly connected to the surface of the bidirectional lead screw 7. An adjusting groove 14 is formed on the surface of the adjusting block 11, and a slider is slidably connected to the inner wall of the adjusting groove 14. The slider plate 15 has a tool holder 16 fixedly connected to one side, and a disc cutter 17 fixedly connected to the lower end of the tool holder 16. The grip handle 1 is rotatably connected to the mounting base 2, and the angle of the grip handle 1 can be adjusted to facilitate the grip and push of the operator. When the bidirectional lead screw 7 rotates, the adjusting block 11 can move along the lead screw axis to adjust the spacing of the cutters. The adjusting groove 14 on the surface of the adjusting block 11 slides with the slider plate 15, allowing the slider plate 15 to drive the tool holder 16 and the disc cutter 17 to slide independently on the adjusting block 11, so as to achieve fine adjustment of a single cutter and thus adapt to diverse cutting operation needs.

[0024] Reference Figure 2 and Figure 3As shown, in this embodiment: the number of adjusting blocks 11 is set to two sets, and the two sets of adjusting blocks 11 are symmetrically distributed on the surface of the bidirectional lead screw 7. A sliding hole 13 is formed on the surface of each adjusting block 11. A guide rod 8 is slidably connected to the inner wall of the sliding hole 13. The two ends of the guide rod 8 are fixedly connected to the surface of the side plate 6. Multiple positioning holes 18 are evenly formed on the inner wall of the adjusting groove 14. A positioning bolt 19 is provided on the surface of the slider plate 15. The positioning bolt 19 is threadedly connected to the inner wall of the positioning hole 18. The two sets of adjusting blocks 11 are symmetrically distributed on the surface of the bidirectional lead screw 7. The adjustment block 11 can move synchronously in opposite directions when the lead screw rotates, ensuring the symmetry and consistency of the tool spacing adjustment on both sides. At the same time, the sliding hole 13 on the surface of the adjustment block 11 slides with the guide rod 8, and the two ends of the guide rod 8 are fixed to the side plate 6, which can effectively limit the rotational freedom of the adjustment block 11 and ensure that it moves linearly along the lead screw axis. After the slider plate 15 drives the tool to complete the fine adjustment, the slider plate 15 can be firmly fixed on the adjustment block 11 by locking the positioning bolt 19 with the corresponding positioning hole 18, preventing the slider plate 15 from shifting due to vibration or external force during operation, and ensuring the stability of the tool spacing.

[0025] Reference Figure 1 and Figure 3 As shown, specifically, one end of the bidirectional lead screw 7 is fixedly connected to a handle 10, the top of the adjusting block 11 is provided with an indicator arrow 20, the connection between the grip 1 and the mounting base 2 is provided with an adjusting knob 4, and one end of the grip 1 is fixedly connected to an anti-slip sleeve 3. Through the handle 10 fixedly connected to one end of the bidirectional lead screw 7, the operating intensity can be reduced by increasing the lever arm, so that the operator can easily drive the bidirectional lead screw 7 to rotate without the aid of additional tools; the indicator arrow 20 on the top of the adjusting block 11 can accurately correspond to the scale line 9 on the surface of the bearing plate 5, so that the operator can quickly read and control the tool spacing, further improving the adjustment accuracy; the adjusting knob 4 at the connection between the grip 1 and the mounting base 2 can be locked after the grip 1 is adjusted to an angle, preventing the angle of the mounting base 2 from shifting due to vibration or external force during operation. At the same time, the anti-slip sleeve 3 fixedly connected to one end of the grip 1 can effectively prevent slippage caused by sweaty hands or uneven force during operation by increasing the friction between the hand and the grip 1, thus improving the grip stability.

[0026] Working principle: Through the rotatable connection between the grip handle 1 and the mounting base 2, the operator can adjust the angle of the grip handle 1 according to the work requirements for easy gripping and pushing. After adjustment, it is locked and fixed by the adjustment knob 4 at the connection between the grip handle 1 and the mounting base 2 to prevent angle deviation during operation. Rotating the handle 10 at one end of the bidirectional lead screw 7 can easily drive the bidirectional lead screw 7 to rotate by increasing the lever arm of the handle 10. This causes the two sets of adjusting blocks 11 symmetrically distributed on the surface of the bidirectional lead screw 7 to move synchronously in opposite directions along the lead screw axis. At the same time, the adjusting blocks 11 cooperate with the guide rod 8 fixed on the side plate 6 through the surface sliding hole 13 to ensure axial movement. Linear motion avoids rotational deviation. The marking arrow 20 on the top of the adjusting block 11 corresponds to the scale line 9 on the surface of the bearing plate 5, which facilitates quick reading and control of the tool spacing. When fine adjustment of a single tool is required, the slider plate 15 can slide independently along the adjusting groove 14 on the surface of the adjusting block 11, driving the tool holder 16 and the disc tool 17 to adjust their positions. After fine adjustment, the positioning bolt 19 on the surface of the slider plate 15 is threadedly connected to the positioning hole 18 on the inner wall of the adjusting groove 14 to achieve locking and fixation, preventing displacement due to vibration or external force during operation. In addition, the anti-slip sleeve 3 at one end of the grip 1 increases the friction to improve grip stability.
