Description

Technical Field

[0001] This utility model relates to the field of label processing technology, and in particular to a constant tension winding and pressing device for roll-type labels. Background Technology

[0002] A label is a carrier that is attached to the surface or inside of an object to carry information, identify functions, or enable specific interactions. Its core is to transmit structured or unstructured data in physical or digital form, serving the needs of scenarios such as identification, tracking, classification, and decoration. During the production of labels, a winding device is required to wind up the label rolls.

[0003] Current label winding machines have certain shortcomings when winding labels. They cannot monitor the tension and compression of the label roll in real time, which can cause damage to the label roll. To address this issue, we propose a constant tension winding and pressing device for roll-type labels. Utility Model Content

[0007] In a further embodiment, each of the sliding slots has a groove on its inner bottom wall, and a support spring is fixedly connected to the inner bottom wall of each groove. The top of each support spring is fixedly connected to the bottom surface of the support block.

[0008] In a further embodiment, a third bearing is fixedly embedded on the upper surface of each support block, an adjusting screw is fixedly connected to the inner ring of each third bearing, a threaded hole is opened on the upper surface of each support plate, and a rotating wheel is fixedly connected to the top of each adjusting screw through the threaded hole.

[0009] In a further embodiment, a bracket is fixedly connected to the upper surface of the winding table, and a roller is rotatably hinged to the inner wall of the bracket via two fourth bearings.

[0010] In a further embodiment, a PLC control panel is fixedly connected to the front of the winding table, and the PLC control panel is electrically connected to the servo motor via wires.

[0011] In a further embodiment, protective sleeves are fixedly connected to the outer surfaces of the support roller and the extrusion roller, and the protective sleeves are made of rubber.

[0012] In a further embodiment, the bottom surface of the winding table is fixedly connected to two mounting legs, and the outer surface of each mounting leg is fixedly connected to two mounting plates, and the upper surface of each mounting plate is provided with mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device, with its winding frame, servo motor, and idler rollers, enables the winding of roll-type labels. Through a support frame, load cells, and a PLC control panel, the load cells detect elastic deformation and convert it into a measurable electrical signal, allowing for precise tension measurement of the roll-type labels.

[0022] Please see Figure 1-5 In this utility model, a constant tension winding and pressing device for roll-type labels includes a winding table 1, a winding frame 4 fixedly connected to the upper surface of the winding table 1, a servo motor 41 installed at the input end of the winding frame 4, a support frame 5 fixedly connected to the upper surface of the winding table 1, a weighing sensor 51 fixedly embedded on the upper surface of the support frame 5, the weighing sensor 51 being a strain gauge type sensor, two support plates 6 fixedly connected to the upper surface of the winding table 1, a first bearing 7 fixedly embedded on the side of the two support plates 6 that are close to each other, a support roller 8 fixedly connected to the inner ring of the two first bearings 7, a pressure monitoring sensor 11 fixedly embedded on the upper surface of the support roller 8, a sliding groove 12 opened on the outer surface of each support plate 6, a support block 13 snapped into the inner wall of each sliding groove 12, a second bearing 14 fixedly embedded on the side of the two support blocks 13 that are close to each other, and a compression roller 15 fixedly connected to the inner ring of the two second bearings 14.

[0023] Each sliding groove 12 has a groove 16 on its inner bottom wall, and a support spring 17 is fixedly connected to the inner bottom wall of each groove 16. The top of each support spring 17 is fixedly connected to the bottom surface of the support block 13, which can provide elastic support for the support block 13 and facilitate the adjustment of the extrusion roller 15. A third bearing 19 is fixedly embedded on the upper surface of each support block 13, and an adjusting screw 20 is fixedly connected to the inner ring of each third bearing 19. A threaded hole 18 is opened on the upper surface of each support plate 6, and a rotating wheel 21 is fixedly connected to the top of each adjusting screw 20 through the threaded hole 18, which can move the support block 13 up and down, which facilitates the adjustment of the height of the extrusion roller 15. A bracket 10 is fixedly connected to the upper surface of the winding table 1. The inner wall of the bracket 10 is rotatably hinged to a roller 102 through two fourth bearings 101, which can support the roll label and facilitate the winding operation of the roll label.

[0024] A PLC control panel 2 is fixedly connected to the front of the winding table 1. The PLC control panel 2 is electrically connected to the servo motor 41 via wires, which can easily control the device and facilitate the winding operation of the roll label. Protective sleeves 9 are fixedly connected to the outer surfaces of the support roller 8 and the extrusion roller 15.

[0025] The working principle of this utility model is as follows:

[0026] In use, the winding table 1 is first installed and fixed using the mounting plate 31, mounting holes 32, and mounting legs 3. During winding, the roll label is lifted by the roller 102, and the roll label passes through the support roller 8 and the extrusion roller 15, and is pressed onto the weighing sensor 51. Then, it is tied to the winding frame 4. The servo motor 41 is controlled by the PLC control panel 2 to wind the roll label. During winding, the roll label presses the weighing sensor 51, which senses the deformation of the roll label through its internal strain gauge, thereby achieving accurate measurement of the roll label tension. At the same time, according to the constant pressure tightening requirement, the rotating wheel 21 and the adjusting screw 20 are rotated. Through the threaded connection with the threaded hole 18, the extrusion roller 15 is driven to move downward and approach the support roller 8 to tighten the roll label by an appropriate amount, thereby achieving constant tension tightening and winding of the roll label.
