Description

Technical Field

[0001] This utility model relates to the field of label machine technology, specifically a label peeler. Background Technology

[0002] Labels are widely used in modern commodity circulation and manufacturing. Various products require labels to identify important information such as brand, specifications, instructions for use, and production date. Labels are usually sold in rolls, with a backing paper and the label faceplate adhered to it using adhesive. Label peelers are used to facilitate easy removal of the labels.

[0003] Chinese patent CN219447581U discloses a label peeler that uses a crank handle to make a turntable drive the take-up roller and the limiting rod to rotate synchronously, thereby achieving the purpose of winding up the label roll.

[0004] However, the aforementioned patent requires manual winding of the label roll after the label has been peeled off, resulting in low automation. Operators need to peel off the label stickers while turning the crank handle, which is not only physically demanding but also makes continuous operation difficult and reduces work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a label peeler to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows.

[0007] A label peeler includes two symmetrically distributed upright plates. A conveying roller is rotatably mounted between the two upright plates via a first shaft. A drive mechanism capable of rotating the first shaft is provided on the inner side of one of the upright plates. A peeling sheet is installed between the two upright plates. A housing is rotatably mounted between the two upright plates via a second shaft. A pressure roller is rotatably mounted between the inner walls of the housing via a third shaft. When the housing is flipped between the two upright plates, the pressure roller abuts against the conveying roller. A winding roller is provided on the outer surface of the second shaft. A transmission mechanism is provided between the third shaft and the second shaft, which can drive the second shaft to rotate and wind up the label roll when the third shaft rotates.

[0008] Therefore, by setting up a transmission mechanism, the drive mechanism can drive the conveyor roller to rotate while conveying the label roll, and simultaneously drive the take-up roller to rotate and take up the label roll after the label has been peeled off. This achieves the purpose of conveying and taking up simultaneously without manual intervention, thereby improving the degree of automation, reducing the labor intensity of the operator, and achieving the purpose of continuous operation.

[0009] Furthermore, the drive mechanism includes a drive motor mounted on the inner side of the upright plate via a mounting bracket, a drive gear mounted on the end of the output shaft of the drive motor, and a driven gear mounted on the outer surface of the first shaft, the driven gear meshing with the drive gear.

[0010] Furthermore, the transmission mechanism includes a transmission rubber wheel mounted on the outer surface of the third shaft, a first driven rubber wheel rotatably mounted on the inner wall of the housing, and the first driven rubber wheel coaxially sleeved on the outer side of the second shaft, with the transmission rubber wheel in close contact with the first driven rubber wheel. A second driven rubber wheel is mounted on the outer surface of the second shaft, and a friction block is mounted on the outer surface of the first driven rubber wheel via a lifting mechanism, the friction block contacting the outer surface of the second driven rubber wheel.

[0011] Furthermore, the lifting mechanism includes a fixed block mounted on the outer surface of the first driven rubber wheel. Two limiting rods are slidably disposed inside the fixed block, and a mounting block is mounted on the ends of the two limiting rods. A friction block is disposed on the outer side of the mounting block. A screw is rotatably connected to the outer surface of the mounting block, and the end of the screw extends through to the other side of the fixed block and is threadedly connected thereto.

[0012] Furthermore, a telescopic rod is installed on the outer surface of the mounting block, the end of the telescopic rod is connected to the friction block, and a spring is sleeved on the outer surface of the telescopic rod, with the two ends of the spring abutting against the mounting block and the friction block respectively.

[0013] Furthermore, at least two friction blocks are provided, and the two friction blocks are distributed at equal angles around the second shaft along the same axis.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. By setting up a transmission mechanism, this utility model can drive the conveying roller to rotate and transport the label roll at the same time as the drive mechanism drives the conveying roller to rotate and transport the label roll after peeling off the label. This achieves the purpose of simultaneous conveying and winding without manual intervention, thereby improving the degree of automation, reducing the labor intensity of the operator, and achieving the purpose of continuous operation.

[0016] 2. This utility model, through the setting of the lifting mechanism, can adjust the frictional resistance between the friction block and the second driven rubber wheel. Since the conveying and winding lengths of the label roll are inconsistent when the conveying roller and the winding roller rotate, and the winding efficiency of the winding roller is greater than that of the conveying roller, by adjusting the frictional resistance of the friction block and the second driven rubber wheel, when the winding roller winds the label roll to a tensioned state, the friction block slips on the outer surface of the second driven rubber wheel, thereby reducing the rotational speed of the winding roller to adapt to the winding speed of the label roll, thus ensuring normal winding of the label roll while avoiding paper breakage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5As shown, a label peeler includes two symmetrically distributed upright plates 1. A conveying roller 102 is rotatably mounted between the two upright plates 1 via a first shaft 101. A drive mechanism 2 capable of driving the first shaft 101 to rotate is provided on the inner side of one of the upright plates 1. A peeling sheet 103 is installed between the two upright plates 1. A housing 105 is rotatably mounted between the two upright plates 1 via a second shaft 104. A pressure roller 107 is rotatably mounted between the inner walls of the two sides of the housing 105 via a third shaft 106. When the housing 105 is flipped between the two upright plates 1, the pressure roller 107 abuts against the conveying roller 102. A winding roller 108 is provided on the outer surface of the second shaft 104. A transmission mechanism 3 is provided between the third shaft 106 and the second shaft 104. The transmission mechanism 3 can drive the second shaft 104 to rotate and wind up the label roll when the third shaft 106 rotates.

[0025] In use, the label roll passes over the conveyor roller 102, wraps back around the end of the peeling strip 103, and passes between the pressure roller 107 and the conveyor roller 102. Then, the end of the label roll is connected to the take-up roller 108. When the first shaft 101 is driven to rotate by the drive mechanism 2, the first shaft 101 drives the conveyor roller 102 to rotate, which in turn works with the pressure roller 107 to achieve the purpose of conveying the label roll. When the label passes the end of the peeling strip 103, due to the poor deformation ability of the label, the label peels off the roll and separates from it under the large bending of the label roll.

[0026] At the same time, through the setting of the transmission mechanism 3, the drive mechanism 2 can drive the conveying roller 102 to rotate and convey the label roll paper while driving the conveying roller 108 to rotate and rewind the label roll paper after peeling off the label, so as to achieve the purpose of conveying and rewinding at the same time without manual intervention, thereby improving the degree of automation, reducing the labor intensity of the operator, and achieving the purpose of continuous operation.

[0027] Furthermore, by setting the housing 105, when it is opened, it can drive the pressure roller 107 to separate from the conveying roller 102, thereby facilitating the passing of the label roll paper between the conveying roller 102 and the pressure roller 107. When the housing 105 is closed, it can drive the conveying roller 102 to press the label roll paper onto the conveying roller 102, thereby ensuring the stability of the label roll paper conveying and avoiding slippage.

[0028] In addition, a latching element is provided between the upright plate 1 and the housing 105. The latching element is used to lock the housing 105 when it is closed, and the latching element also has an unlocking effect so that the housing 105 can be opened. The latching element adopts existing technology, and its specific structure and working principle will not be described in detail, nor is it shown in the attached drawings.

[0029] Preferably, the drive mechanism 2 includes a drive motor 202 mounted on the inner side of the upright plate 1 via a mounting bracket 201. A drive gear 203 is mounted on the end of the output shaft of the drive motor 202. A driven gear 204 is mounted on the outer surface of the first shaft 101. The driven gear 204 meshes with the drive gear 203.

[0030] When the drive motor 202 is started, it drives the drive gear 203 to rotate. Since the drive gear 203 and the driven gear 204 mesh with each other, the purpose of driving the conveyor roller 102 to rotate is achieved.

[0031] Preferably, the transmission mechanism 3 includes a transmission wheel 301 mounted on the outer surface of the third shaft 106, a first driven wheel 302 rotatably mounted on the inner wall of the housing 105, and the first driven wheel 302 coaxially sleeved on the outer side of the second shaft 104, with the transmission wheel 301 in close contact with the first driven wheel 302. A second driven wheel 303 is mounted on the outer surface of the second shaft 104, and a friction block 304 is mounted on the outer surface of the first driven wheel 302 via a lifting mechanism 4, with the friction block 304 in contact with the outer surface of the second driven wheel 303.

[0032] When the conveyor roller 102 rotates, it drives the pressure roller 107 and the third shaft 106 to rotate accordingly through friction. The third shaft 106 drives the transmission rubber wheel 301 to rotate. Since the transmission rubber wheel 301 is in close contact with the first driven rubber wheel 302, it can drive the first driven rubber wheel 302 to rotate under the action of friction. The inner surface of the first driven rubber wheel 302 does not contact the outer surface of the second shaft 104, so it will not directly drive the second shaft 104 to rotate. When the first driven rubber wheel 302 rotates, the lifting mechanism 4 drives the friction block 304 to rotate around the second shaft 104. Through the friction between the friction block 304 and the second driven rubber wheel 303, the second shaft 104 can be driven to rotate, so that the take-up roller 108 can take up the label roll.

[0033] As the thickness of the label roll wound on the take-up roller 108 increases, it is equivalent to increasing the diameter of the take-up roller 108. Each time the take-up roller 108 rotates once, the length of the wound label roll is inconsistent, which can easily lead to the label roll becoming loose or tearing during the winding process.

[0034] In response to the above situation, this application sets the transmission ratio of the transmission roller 301 to be greater than that of the first driven roller 302. Therefore, under the drive of the drive mechanism 2, the winding efficiency of the take-up roller 108 is greater than that of the conveying roller 102. By adjusting the friction resistance of the friction block 304 and the second driven roller 303 through the lifting mechanism 4, when the take-up roller 108 winds the label roll to a tensioned state, the friction block 304 slips on the outer surface of the second driven roller 303, thereby reducing the rotation speed of the take-up roller 108 to adapt to the winding speed of the label roll, thus ensuring the normal winding of the label roll while avoiding paper breakage.

[0035] Preferably, the lifting mechanism 4 includes a fixing block 401 mounted on the outer surface of the first driven rubber wheel 302. Two limiting rods 402 are slidably disposed inside the fixing block 401. The ends of the two limiting rods 402 are jointly mounted on a mounting block 403, and a friction block 304 is disposed on the outer side of the mounting block 403. A screw 404 is rotatably connected to the outer surface of the mounting block 403. The end of the screw 404 extends through to the other side of the fixing block 401 and is threadedly connected thereto.

[0036] Since the limiting rod 402 limits the mounting block 403, when the screw 404 is turned, the mounting block 403 can be driven to rise and fall vertically under the action of the threaded connection. This adjusts the contact force between the friction block 304 and the second driven rubber wheel 303, allowing for adaptive adjustment of the friction force between them based on the material, hardness, and whether the label roll is prone to breakage. This ensures normal winding of the label roll while preventing paper breakage.

[0037] Preferably, a telescopic rod 5 is installed on the outer surface of the mounting block 403, the end of the telescopic rod 5 is connected to the friction block 304, and a spring 501 is sleeved on the outer surface of the telescopic rod 5, with the two ends of the spring 501 abutting against the mounting block 403 and the friction block 304 respectively.

[0038] By setting the telescopic rod 5 and the spring 501, the contact between the friction block 304 and the second driven rubber wheel 303 is changed from hard contact to elastic contact, which increases the adjustment range of the friction force of the friction block 304 and the second driven rubber wheel 303 and facilitates operation.

[0039] Preferably, at least two friction blocks 304 are provided, and the two friction blocks 304 are distributed at equal angles to the coaxial line around the second shaft 104.

[0040] This ensures uniform force distribution and improves transmission efficiency.
