Description

Technical Field

[0001] The utility model relates to the field of thermal paper production equipment, in particular to an adjustable sleeve of a winding shaft of a thermal paper slitting machine and a slitting machine. Background Art

[0002] Thermal paper is a special consumable for digital all-in-one quick printing machines. Currently, the thermal paper produced by composite production is a large roll of semi-finished products, and generally each large roll of semi-finished products has a width of 800 to 1000mm and a length of 6000m. Therefore, the large roll of semi-finished products must be cut into small rolls of finished products by a slitting machine before they can be used by users.

[0003] The width of thermal paper used in different models of digital all-in-one quick printing machines on the market is different, ranging from 220 to 320 mm. In addition, each small roll of finished product needs to be rolled up with a thermal paper core of the corresponding size, and the knife seat of the slitting machine also has different slitting blades.

[0004] The existing reel of the slitting machine is equipped with a sleeve for simultaneously limiting the circumferential rotation and axial rotation of the thermal paper core. When multiple thermal paper cores are movably sleeved on the reel and are all located on the side of the sleeve away from the fixed end of the reel, one end of the sleeve is first pressed against the fixed end of the leftmost side of the reel, and then the other end of the sleeve is pressed against the thermal paper core on the leftmost side, and the thermal paper core on the rightmost side is restricted by the other fixed end of the reel to ensure that all the thermal paper cores rotate synchronously with the reel, and the fixed position of the thermal paper core on the reel is restricted by the length of the sleeve. Therefore, the length of the sleeve needs to match the length of the thermal paper core to ensure that the two ends of the thermal paper core are aligned with the corresponding slitting edges one by one, thereby ensuring the normal reeling of the thermal paper. In this way, sleeves of different lengths are required to match thermal paper cores of different lengths, which results in many and complicated sleeve models, and a long machine adjustment time when switching between different machine models, and low production efficiency.

[0005] In addition, when the sleeve is used for a long time or deformed, the length of the sleeve is prone to deviation, which may cause the two ends of the thermal paper core to be unable to align with the slitting edge, thereby affecting normal winding. Utility Model Content

[0006] To this end, in order to solve the above-mentioned problem, the utility model provides an adjustable sleeve for the winding shaft of a thermal paper slitting machine and a slitting machine, which is threadedly connected between an inner sleeve and an outer sleeve and flexibly adjusts the total length of the sleeve unit according to the different lengths of the thermal paper core to ensure the normal winding of the thermal paper.

[0009] Furthermore, the winding shaft has a fixing portion and a paper core installation area located on one side of the fixing portion, and the sleeve unit and the paper core unit are both sleeved in the paper core installation area; one end of the inner sleeve has a fixing ring for fixing the fixing portion connected to the winding shaft.

[0010] Furthermore, the fixing ring has a fixing hole for screwing the fixing part.

[0011] Furthermore, a paper core limiting ring for limiting and fixing the thermal paper core is provided at one end of the paper core unit which faces away from the sleeve unit, the paper core limiting ring comprises a limiting ring and an abutting sleeve which are connected to each other, the inner wall of the limiting ring has a thread, the winding shaft is provided with a limiting threaded portion which is threadedly connected to the limiting ring, the limiting ring is threadedly connected to the limiting threaded portion, and the end of the abutting sleeve presses the end of the paper core unit which faces away from the sleeve unit to limit the circumferential and axial movement of the paper core unit.

[0012] Furthermore, the inner diameter of the abutting sleeve is at least 1 mm larger than the outer diameter of the winding shaft.

[0013] Furthermore, the inner diameter of the inner sleeve is at least 1 mm larger than the outer diameter of the winding shaft.

[0016] The technical solution provided by the utility model has the following beneficial effects:

[0017] The inner sleeve and the outer sleeve are connected by a threaded connection to realize the outer sleeve being screwed in or out of the inner sleeve, and the total length of the sleeve unit is flexibly adjusted according to the different lengths of the thermal paper core, thereby ensuring that the end of the outer sleeve can press the paper core unit to ensure the normal winding of the thermal paper, avoiding the existing sleeve reserves with many and complicated models, and effectively shortening the machine adjustment time required for switching between different models, thereby improving production efficiency.

[0018] Moreover, when the sleeve unit is used for a period of time and causes local wear and tear, resulting in deviations in its total length, the length of the sleeve unit can be fine-tuned to achieve realignment of the two ends of the thermal paper core with the slitting edge of the slitting machine during winding.

[0029] In this embodiment, the number of sleeve units 6 is one, and a plurality of thermal paper cores 2 are arranged in a straight line along the axial direction of the winding shaft 1 of the slitting machine and are all located on the right side of the sleeve unit 6 .

[0030] When it is necessary to install multiple thermal paper cores 2 on the winding shaft 1 and ensure that they are aligned with the slitting edge of the slitting machine, first put the sleeve unit 6 on the winding shaft 1, and fix the inner sleeve 4 of the sleeve unit 6 on the left end of the winding shaft 1, then put all the thermal paper cores 2 on the winding shaft 1 in turn and rely on the static friction between the end faces of each thermal paper core 2 to form the paper core unit, and then assemble the winding shaft 1 on the slitting machine. At this time, the thermal paper core 2 on the far right is also abutted to form a fixed restriction, and then the outer sleeve 5 is screwed in or out on the inner sleeve 4 to further adjust the winding position of the paper core unit on the winding shaft 1, so that the two ends of each thermal paper core 2 are respectively aligned with the slitting edge of the slitting machine, and at the same time ensure that the outer sleeve 5 presses the paper core unit, so that all the thermal paper cores 2 and the sleeve unit 6 can rotate synchronously with the winding shaft 1, thereby ensuring the normal winding of the thermal paper.

[0031] The inner sleeve 4 and the outer sleeve 5 are connected by a threaded connection to realize the outer sleeve 5 being screwed in or out of the inner sleeve 4, and the total length of the sleeve unit 6 is flexibly adjusted according to the different lengths of the thermal paper core 2, thereby ensuring that the end of the outer sleeve 5 can press the paper core unit tightly to ensure the normal winding of the thermal paper, and can also avoid the existing sleeve reserves of multiple and complicated models, and effectively shorten the machine adjustment time required for switching between different models, thereby improving production efficiency.

[0032] Moreover, when the sleeve unit 6 is partially worn after being used for a period of time and causes deviation in its total length, the length of the sleeve unit 6 can be finely adjusted to achieve realignment of the two ends of the thermal paper core 2 with the slitting edge of the slitting machine during winding.

[0036] Then, the outer sleeve 5 is rotated again to move the outer sleeve 5 toward the paper core unit until both ends of each thermal paper core 2 are aligned with the corresponding slitting edges, and finally, the paper core limiting ring 313 is rotated again to ensure that the abutting sleeve 32 also presses the paper core unit to ensure that the winding shaft 1, the sleeve unit 6, the paper core limiting ring 313 and the thermal paper core 2 of the paper core unit form a whole and rotate without sliding against each other.
