Description

Technical Field

[0001] The utility model relates to the field of mica paper processing, in particular to a mica paper trimming device. Background Art

[0002] Mica paper is made of mica stone, which is broken into pulp and papermaking through thermochemical or hydraulic stripping, and then cut into continuous roll paper or single paper. Mica paper has heat-resistant insulation and high temperature resistance, and is widely used in the insulation of electrical and electronic components in high temperature environments. After the pulp is made into mica paper through papermaking, it is necessary to cut both sides of the paper neatly before rolling it up. Usually, a roller cutter is used for trimming. The roller cutter is a consumable part. After the roller cuts the mica paper for a period of time, it will cause a certain degree of wear. If the roller cutter is not replaced in time, it will affect the quality of the trimming.

A plurality of lower roller cutters 903 are installed on the second sleeve 901 by screws. Since the lower roller cutters 903 wear faster than the upper roller cutters 503, sometimes only the lower roller cutters 903 need to be replaced. When one lower roller cutter 903 is worn, the second sleeve 901 is moved and the remaining lower roller cutters 903 can be used, which is convenient to use. Two adjustment mechanisms are slidably installed on the positioning guide rod 3, and the adjustment mechanism is used to drive the first sleeve 501 to move, thereby adjusting the position of the upper roller cutter 503. The base 1 is provided with an operating mechanism for moving the sleeve mechanism and a power mechanism for driving the cutting roller 2 to rotate.

[0025] The locking assembly includes a locking ring 504, which is sleeved on the first sleeve 501. A threaded seat 505 is welded on the locking ring 504. The threaded seat 505 is internally threaded with a first locking bolt 506. The first sleeve 501 is provided with a locking hole 507 that matches the first locking bolt 506. The upper roller cutter 503 is installed between the fixing ring 502 and the locking ring 504. The locking ring 504 is sleeved on the first sleeve 501, the first locking bolt 506 and the locking hole 507 are aligned, and the first locking bolt 506 is rotated to enter the locking hole 507, thereby completing the fixation of the locking ring 504, so that the locking ring 504 and the fixing ring 502 clamp and fix the upper roller cutter 503.

The screw rod 702 rotates to drive the movable plate 401 to move. When the upper roller cutter 503 needs to be replaced, the movable plate 401 is moved away from the cutting roller 2, so that the positioning guide rod 3 is disengaged from the sleeve 402, and the cutting roller 2 is disengaged from the first connecting sleeve 404. Then, the sliding sleeve 601 is removed from the positioning guide rod 3, so that the first sleeve 501 is removed from the cutting roller 2. After replacing the upper roller cutter 503, the sliding sleeve 601 is sleeved on the positioning guide rod 3, and the first sleeve 501 is sleeved on the cutting roller 2 at the same time. The movable plate 401 is reset to complete the replacement of the upper roller cutter 503. The operation is simple and fast, and it is easy to use.

The second rotating shaft 803 is rotatably connected to the fixed plate 102. A second connecting sleeve 804 is fixed to one end of the second rotating shaft 803. The end of the cutting roller 2 away from the sleeve mechanism is fixed in the second connecting sleeve 804. The cutting roller 2 and the second connecting sleeve 804 are fixed by screws. In order to reduce the disassembly of the cutting roller 2, the cutting roller 2 and the second connecting sleeve 804 are kept fixed under normal conditions. When the cutting roller 2 needs to be replaced, the screws on the second connecting sleeve 804 can be removed to remove the cutting roller 2, which is convenient for disassembly and assembly.

[0030] Working principle: When in use, the mica paper passes between the two cutting rollers 2, the motor 801 drives the gear 802 to rotate, the gear 802 drives the cutting roller 2 to rotate, the cutting roller 2 uses the T-slot 201 to drive the first sleeve to rotate the sleeve 501 and the second sleeve 901 to rotate, so that the upper roller cutter 503 and the lower roller cutter 903 rotate to perform the edge trimming operation on the mica paper. When the upper roller cutter 503 needs to be replaced, the screw rod 702 is first rotated by the hand wheel 703, and the screw rod 702 drives the movable plate 401 away from the cutting roller 2, so that the positioning guide rod 3 is moved from the sleeve 40 2, the cutting roller 2 is disengaged from the first connecting sleeve 404, the second locking bolt 604 is twisted to release the fixing between the sliding sleeve 601 and the positioning guide rod 3, and then the sliding sleeve 601 is moved to remove it from the positioning guide rod 3, the sliding sleeve 601 drives the connecting rod 602 and the collar 603 to move, and the collar 603 drives the first sleeve 501 to move, so that the first sleeve 501 is removed from the cutting roller 2, and then the first locking bolt 506 is twisted to make it disengage from the locking hole 507, so that the fixing between the locking ring 504 and the first sleeve 501 can be released, Remove the locking ring 504 and the upper roller cutter 503, replace the new upper roller cutter 503, and then fix the locking ring 504 to the first sleeve 501, so that the fixing ring 502 and the locking ring 504 clamp the upper roller cutter 503, and then put the sliding sleeve 601 and the first sleeve 501 on the positioning guide rod 3 and the cutting roller 2 respectively, rotate the screw rod 702 to reset the movable plate 401, and insert the positioning guide rod 3 and the cutting roller 2 into the sleeve 402 and the first connecting sleeve 404 respectively to complete the replacement of the upper roller cutter 503. 3 to accommodate mica papers of different widths. The sliding sleeve 601 is fixed to the positioning guide rod 3 by twisting the second locking bolt 604 to fix the position of the upper roller cutter 503, and the trimming operation can be continued. When replacing the upper roller cutter 503, the second sleeve 901 can also be removed at the same time, and then all the lower roller cutters 903 on the second sleeve 901 can be replaced. When only one lower roller cutter 903 is worn, the second sleeve 901 does not need to be disassembled, and the remaining lower roller cutters 903 can be used by moving the second sleeve 901.
