When the frame is in use, the position of the roll paper can be fixed by using the active clamping head 21 and the driven clamping head 17 on another clamping structure.

[0022] A rotating structure is provided at the top of one end of the base 1, and the rotating structure includes a hydraulic telescopic rod 48 fixedly connected to the top of the base 1, and the other end of the hydraulic telescopic rod 48 is fixedly connected to a rotating motor 6, and the end of the output shaft of the rotating motor 6 is fixedly connected to a gear 7 through a reducer, and the gear 7 is adapted to the gear ring 18. When the web moves to the cutting position, the gear 7 and the gear ring 18 at one end of the web can be in a meshing state, and the rotation of the rotating motor 6 can drive the gear 7 fixedly connected thereto to rotate, and the gear 7 drives the gear ring 18 meshing therewith to rotate, and the rotating gear ring 18 drives the active clamping head 21 fixedly connected thereto to rotate, and the rotating active clamping head 21 can drive the web to rotate, so as to facilitate the cutting of the web.

[0023] The return chamber 3 and the translation chamber 4 form a U-shaped structure. A return structure is provided at one end of the inner cavity of the return chamber 3 away from the partition plate 2. The return structure includes a screw rod 12 movably connected to the return chamber 3. The outer ring of the screw rod 12 is threadedly connected to a threaded block. A hydraulic telescopic rod 13 is fixed to the top of the threaded block. The top of the hydraulic telescopic rod 13 and the end away from the partition plate 2 are both in contact with the inner wall of the return chamber 3. A return motor 14 is fixedly connected to the inner cavity of the return chamber 3. The end of the output shaft of the return motor 14 is fixedly connected to the end of the screw rod 12. Through the setting of the return motor 14, the rotation of the return motor 14 can drive the screw rod 12 fixedly connected thereto to rotate, and the rotation of the screw rod 12 allows the hydraulic telescopic rod 13 to move in the direction where the screw rod 12 is located.

[0024] The end of the hydraulic telescopic rod 13 away from the threaded block is adapted to the inner cavity of the clamping tube 20. When the end of the hydraulic telescopic rod 13 away from the threaded block is clamped with the inner cavity of the clamping tube 20, the extension and retraction of the hydraulic telescopic rod 13 can change the position of the clamping structure, so that the clamping structure can be moved from the translation cavity 4 to the return cavity 3, and under the action of the screw rod 12, the return motor 14 and the threaded block, the clamping structure can move from the end close to the rotating structure of the base 1 to the end of the base 1 away from the rotating structure, and when the hydraulic telescopic rod 13 is extended, the clamping structure can be moved from the return cavity 3 to the translation cavity 4 again. The clamping structure changes its position, so that there are always three clamping structures in the translation cavity 4, and then during the cutting process of the roll paper, the roll paper to be cut can be clamped and fixed by the two clamping structures, thereby improving the working efficiency of the paper cutter.

[0025] A translation structure is provided in the inner cavity of the translation cavity 4, and the translation structure includes a hydraulic telescopic rod 2 9 fixedly connected to the inner cavity of the translation cavity 4, a hydraulic telescopic rod 3 10 fixedly connected to the hydraulic telescopic rod 2 9, and a translation frame fixedly connected to the other end of the hydraulic telescopic rod 3 10, and the translation frame includes a connecting rod 11 fixedly connected to the hydraulic telescopic rod 3 10, and both ends of the connecting rod 11 are provided with a clamp 16 adapted to the clamping block 19, and the clamp 16 is connected to the connecting rod 11 through the hydraulic telescopic rod 5 22. It can be seen from the above description of the translation structure that the extension and retraction of the hydraulic telescopic rod 2 9 can change the position of the translation frame, and the translation frame can drive the two clamping structures clamping the roll paper to move, so that the roll paper can be moved from the loading position to the cutting position, and the extension and retraction of the hydraulic telescopic rod 3 10 can change the distance between the translation frame and the clamping structure, so as to facilitate the clamping or separation of the clamp 16 and the clamping block 19. The extension and retraction of the hydraulic telescopic rod 5 22 can change the distance between the two clamps 16. When the clamps 16 are engaged with the clamping block 19, the change in position between the two clamps 16 can change the position between the two clamping structures, making it easier to separate the roll paper from the active clamping head 21 and the driven clamping head 17.

[0026] An electromagnet 15 is provided at one end of the return chamber 3 close to the rotating structure, and there are two electromagnets 15. When the electromagnet 15 is powered on, the electromagnet 15 is magnetically attracted to the clamping block 19. By setting the electromagnet 15, when the electromagnet 15 is magnetically attracted to the clamping block 19, the position of the clamping structure can be fixed, so that the clamping structure remains stable.

[0027] In some embodiments of the present application, the model of the electromagnet 15 is BJ-DH-50, and the material of the clamping block 19 is metal iron.

[0028] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0029] To sum up: when the roll paper placing frame of the paper cutter is in use, after the clamp 16 is clamped with the clamping block 19 in the two clamping structures away from the rotating structure, the distance between the two clamping structures is changed by the hydraulic telescopic rod 5 22. When the height of the axis of the roll paper is in the same straight line as the axis height of the active clamping head 21 and the driven clamping head 17, the hydraulic telescopic rod 5 22 is contracted. The contraction of the hydraulic telescopic rod 5 22 reduces the distance between the two clamping structures until the roll paper is clamped by the two clamping structures. The hydraulic telescopic rod 29 is contracted, and the hydraulic telescopic rod 29 drives the clamping structure that clamps the roll paper to move through the translation frame until the roll paper is moved to the cutting position. The hydraulic telescopic rod 48 is contracted, and the hydraulic telescopic rod 48 drives the rotating motor 6 and the gear 7 to move until the gear 7 is meshed with the gear ring 18. The rotation of the rotating motor 6 can drive the gear 7 to rotate, and the gear 7 can drive the active clamping head 21 to rotate through the gear ring 18 meshed therewith, and the active clamping head 21 drives the roll paper to rotate, which is convenient for cutting the roll paper. In the process of the web moving from the loading position to the cutting position, the hydraulic telescopic rod 13 extends until the hydraulic telescopic rod 13 is engaged with the clamping structure close to the rotating structure. After the electromagnet 15 close to the rotating structure is powered off, the hydraulic telescopic rod 13 contracts, and the hydraulic telescopic rod 13 drives the clamping structure engaged with it to move from the translation chamber to the return chamber, and the screw rod 12 rotates. The rotation of the screw rod 12 causes the clamping structure in the return chamber to move in the opposite direction of the screw rod 12 until the clamping structure in the return chamber moves to the other end of the return chamber, and the hydraulic telescopic rod 13 extends again. The extension of the hydraulic telescopic rod 13 again causes the clamping structure in the return chamber to move back to the translation chamber, so that during the cutting process of the web, the clamping structure engaged with the hydraulic telescopic rod 13 and another clamping structure close to it can be used in combination to clamp another web to be cut.

[0030] After the web paper is cut, the hydraulic telescopic rod 24 extends, so that the gear 7 is separated from the gear ring 18, and the hydraulic telescopic rod 5 22 extends. The extension of the hydraulic telescopic rod 5 22 increases the distance between the two clamping structures that clamp the cut web paper, and the clamping structure and the cut web paper can be separated. In the process of the extension of the hydraulic telescopic rod 5 22, the clamping structure connected with the hydraulic telescopic rod 13 is away from the rotating structure under the action of the screw rod 12, and the movement of the clamping structure connected with the hydraulic telescopic rod 13 is The moving distance is the same as the extension distance of the hydraulic telescopic rod 5 22, so that the other roll paper to be cut can remain in the clamped state unchanged, and the electromagnet 15 is energized. After the electromagnet 15 and the clamping structure in the cutting position are magnetically attracted, the translation frame is clamped with the clamping structure for clamping the other roll paper to be cut, and the hydraulic telescopic rod 13 contracts until the hydraulic telescopic rod 13 is separated from the clamping tube 20, and the electromagnet 15 close to the translation frame is in a power-off state, and the translation frame drives the other roll paper to be cut to move.
