Technical Field

[0001] This utility model relates to the field of thermal paper slitting machine technology, and in particular to a slitting machine with adjustable thermal paper slitting size. Background Technology

[0002] During the processing of thermal paper, a thermal paper slitting machine is required for precise slitting to avoid insufficient slitting accuracy affecting the finished product qualification rate or causing adverse effects on subsequent printing.

[0003] Existing adjustable thermal paper slitting machines have significant drawbacks in size adjustment: their adjustment mechanisms use traditional bolt fixing methods, requiring repeated bolt disassembly and reassembly for size adjustment, making the process cumbersome and time-consuming; simultaneously, the lack of a positioning reference during adjustment necessitates multiple calibrations after reinstallation to ensure slitting accuracy. These dual deficiencies not only significantly reduce equipment adjustment efficiency but also risk thread wear due to repeated bolt disassembly and reassembly, or slitting size errors due to inaccurate calibration, ultimately affecting the quality of the final product.

A connecting bearing seat 22-3 is fixed to one side of the limiting plate 22-1, and a fixing spline 22-4 is fixed to the inner wall of the connecting bearing seat 22-3. A mounting plate 22-6 is fixed to the bottom of the limiting plate 22-1, and a positioning block 22-5 is fixed to one side of the mounting plate 22-6.

[0046] The connecting bearing housing 22-3 can perform longitudinal installation and positioning without affecting the rotation of the connecting roller 21-1.

[0047] Specifically, the slitting component 21 includes a connecting roller 21-1 disposed on the top of the support base plate 11. A sliding groove 21-3 is provided on the surface of the connecting roller 21-1. A spline groove 21-2 is provided on one side of the connecting roller 21-1. A positioning hole 21-4 is provided on the inner wall of the sliding groove 21-3.

[0048] The sliding groove 21-3 can limit and guide the guide block 24-4, and at the same time improve its sliding efficiency on the surface of the connecting roller 21-1.

[0049] Specifically, the adjusting component 24 includes a cutting tool 24-1 sleeved on the surface of the connecting roller 21-1, and a guide block 24-4 that cooperates with the sliding groove 21-3 is fixed on one side of the cutting tool 24-1.

[0050] Specifically, the adjusting component 24 also includes a movable block 24-2 fixed to the surface of the cutting tool 24-1. A sliding rod 24-7 is movably connected to the inner wall of the movable block 24-2. A limit protrusion 24-8 is fixed to the top of the sliding rod 24-7. A fixing block 24-5 is fixed to the bottom of the sliding rod 24-7. The fixing block 24-5 is fixed to the surface of the cutting tool 24-1.

A return spring 24-6 is sleeved on the surface of the sliding rod 24-7.

[0051] The return spring 24-6 can reset itself by the elastic force generated by its own restoring deformation when the user's hand no longer limits the movable block 24-2.

[0052] When adjusting the cutting size of thermal paper, the user should first calculate the required adjustment size and the number of cutters to be retained before making the adjustment.

[0053] After obtaining the required data, the user first manually pulls the limiting plate 22-1 to make it detach from the inner wall of the supporting base plate 11, then pulls the movable block 24-2 upward to make it drive the plug rod 24-3 to detach from the inner wall of the positioning hole 21-4, then pushes the slitting cutter 24-1 to make it drive the guide block 24-4 to slide along the sliding groove 21-3, and finally detaches from the surface of the connecting roller 21-1.

[0054] Once the number of remaining blades is correct, the user manually pulls the limiting plate 22-1 to detach it from the inner wall of the support base plate 11. Then, the user pulls the movable block 24-2 upwards, causing the insertion rod 24-3 to detach from the inner wall of the positioning hole 21-4. The user then pushes the slitting blade 24-1, causing the guide block 24-4 to slide along the sliding groove 21-3 to the appropriate position. The user then releases the movable block 24-2, allowing the insertion rod 24-3 to spring back to the inner cavity of the corresponding positioning hole 21-4 under the elastic force generated by the return spring 24-6 restoring its deformation. This positions the slitting blade 24-1, thus completing the entire disassembly and adjustment process.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
