[0027] Reference Figure 1 The first aspect of the present invention provides an automatic label slitting device, comprising: a frame 100; a feeding mechanism, disposed on the frame 100, including a feeding roller 210 and a first motor, the feeding roller 210 being arranged horizontally and the first motor driving the feeding roller 210 to rotate; a conveying mechanism, disposed on the frame 100, including a conveying roller 310 and a tensioning assembly, multiple conveying rollers 310 being arranged horizontally, and the tensioning assembly being used to tension the label paper; a slitting mechanism, disposed on the frame 100, including a slitting assembly and a protective component, the slitting assembly being disposed within the protective component and being used to slit the label paper; and a receiving mechanism, disposed on the frame 100, the receiving mechanism being used to individually wind up the separated label papers; wherein the feeding mechanism, conveying mechanism, slitting mechanism, and receiving mechanism are arranged sequentially along the label paper conveying direction.

[0028] The label roll is loaded onto the feeding roller 210, and the first motor drives the feeding roller 210 to rotate. In conjunction with the take-up mechanism, the speed difference between the take-up mechanism and the feeding roller 210 tensions the label roll. The conveying roller 310 conveys the label roll, and the tension component adjusts the tightness of the label roll paper. The slitting component automatically cuts the label roll paper into multiple strips, which are then uniformly rewound by the take-up mechanism. This achieves automatic label roll slitting, reduces labor intensity, and improves efficiency.

[0029] Understandably, referring to Figure 1 and Figure 2 The slitting assembly includes a second motor, a first drive shaft 421, a cutter, and a support shaft 424. The second motor drives the first drive shaft 421 to rotate. The cutter is mounted on the first drive shaft 421, and the support shaft 424 is positioned below the first drive shaft 421, abutting against the cutting edge of the cutter. The second motor drives the first drive shaft 421 to rotate, which in turn drives the cutter to move. The cutter actively cuts the label roll. The support shaft 424 abuts against the cutting edge of the cutter, providing support to the cutting edge, improving the cutting success rate, and preventing paper jams.

[0030] Understandably, referring to Figure 1 and Figure 2 The cutting tool includes a connector and a cutting blade 422. The connector has a connecting shaft 426 arranged axially, and the cutting blade 422 is axially engaged with the connecting shaft 426. The connection of the cutting blade to the connecting shaft 426 by the connector facilitates the disassembly and replacement of the cutting tool, and also makes it easy to adjust the position of the cutting tool on the connecting shaft 426, thus improving convenience.

[0031] Understandably, referring to Figure 2 A locking block 427 is radially movably mounted on the connecting shaft 426. A first spring is positioned between the locking block 427 and the connecting shaft 426. The first spring drives the locking block 427 to protrude from the connecting shaft 426. The blade 422 has a radially opening groove that matches the locking block 427, and the locking block 427 engages with the groove. When the blade 422 is fitted onto the connecting shaft 426, pressing the locking block 427 along the slide groove 323 compresses the first spring, causing the locking block 427 to slide into the groove. The first spring then radially pushes the locking block 427 outward, causing the locking block 427 to radially press against the blade 422. Multiple locking blocks 427 simultaneously radially press against the blade 422, increasing the friction between the locking block 427 and the side wall of the groove, thus securing the blade 422 firmly on the connecting shaft 426. To remove the blade 422, simply press down the locking block 427 to remove it, making the process convenient and quick.

[0032] Specifically, it can be understood that, referring to Figure 2 The connector includes two symmetrical connecting blocks 425, with a clearance groove between the two connecting blocks 425 that matches the first drive shaft 421. A second spring 428 is provided on the connecting shaft 426, arranged circumferentially along the connecting shaft 426, with both ends of the second spring 428 connected to the two connecting blocks 425 respectively. The two connecting blocks 425 are fastened together; if screwed, this allows the connector to be sleeved onto the connecting shaft 426, reducing the difficulty of separating or assembling the connector from the connecting shaft 426. The second spring 428 wraps circumferentially around the connecting shaft 426, and its tension helps maintain a stable connection between the two connecting blocks 425, reducing the risk of separation or detachment.

[0033] Understandably, referring to Figure 1The protective assembly includes a transparent protective cover 411 and a protective frame 413. The protective frame 413 is mounted on the frame 100 and surrounds the slitting mechanism to prevent contact with it and reduce safety risks. The protective cover 411 is hinged to the protective frame 413. The protective cover 411 is transparent, allowing for easy observation of the slitting process inside the protective frame 413. The protective cover 411 is positioned above the cutting tool. The protective frame 413 has a second support block 412. When the protective cover 411 rotates above the cutting tool, it abuts against the second support block 412, which supports the protective cover 411 to prevent contact between it and the cutting tool. When adjustments to the slitting mechanism are needed, the protective cover 411 can be opened for operation, making the process simple and convenient.

[0034] Understandably, referring to Figure 2 A support shaft 424 is sleeved with a first support block 423. The first support block 423 has a groove 429 circumferentially formed, which matches the cutting edge of the blade 422. The groove 429 and the cutting edge of the blade 422 are correspondingly arranged. By cooperating with the cutting edge, the difficulty of the blade 422 cutting the label roll is reduced. At the same time, the cutting edge of the blade 422 is placed in the groove 429, which can prevent the blade 422 from slipping. This improves the cutting accuracy.

[0035] Understandably, referring to Figure 1 and Figure 4 The tensioning assembly includes a tensioning roller 321 and a movable part. The movable part is mounted on the frame 100. The tensioning roller 321 is arranged horizontally and rotatably mounted on the movable part. The tensioning roller 321 is located on the movable end of the movable part, allowing it to move vertically under its own weight or upward under the influence of the label roll.

[0036] Understandably, referring to Figure 4 The movable component includes a movable block 325 and two guide pillars 322. The two guide pillars 322 are symmetrically arranged and vertically positioned. The movable block 325 is slidably connected to the guide pillars 322 along the vertical direction. The tension roller 321 is mounted on the movable block 325. By using two guide pillars 322, the deformation force on one guide pillar 322 is reduced, thereby increasing the service life of the guide pillar 322. The movable block 325 cooperates with the guide pillars 322 to improve the linearity of the movement of the tension roller 321.

[0037] Understandably, referring to Figure 4The movable block 325 has symmetrical grooves 323 on both sides. Multiple balls 324 are mounted on the sidewalls of the grooves 323, allowing them to roll freely. Through the contact between the balls 324 and the guide post 322, the sliding friction between the movable block 325 and the guide post 322 is converted into rolling friction, reducing the frictional force between them and improving the smoothness of movement. This makes the tension roller 321 lighter and improves the effect of adjusting the tightness of the label roll paper.

[0038] Understandably, referring to Figure 1 and Figure 3 The receiving mechanism includes multiple receiving units and a second drive shaft 520. The second drive shaft 520 is vertically arranged. Each receiving unit includes a receiving roller 510, a first helical gear 531, and a second helical gear 532. The receiving roller 510 is arranged horizontally. The first helical gear 531 is sleeved with the receiving roller 510, and the second helical gear 532 is sleeved with the second drive shaft 520. The first helical gear 531 and the second helical gear 532 mesh. A third motor is provided to drive the second drive shaft to rotate. The second drive shaft 520, through the cooperation of the first helical gear 531 and the second helical gear 532, simultaneously drives the multiple receiving rollers 510 to rotate, so that the winding speed of the labels being cut out is synchronized, avoiding uneven speeds from affecting the master roll before cutting.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
