Description

Technical Field

[0001] The utility model relates to the technical field of label paper production, in particular to a supporting and guiding device on a label paper production line. Background Art

[0002] The label paper tape support and guiding device on the label paper production line is a key equipment to ensure production efficiency and product quality. Its main structure includes a supporting device, a guiding device and an adjustment mechanism. The supporting device provides a stable supporting force to prevent the label paper tape from bending or twisting during high-speed operation, and is usually made of metal to ensure sufficient stability and rigidity. The guiding device accurately guides the label paper tape to run along a predetermined path through components such as guide rollers and sliders to avoid deviation or deviation, thereby ensuring the stability and efficiency of the production line; such as a supporting and guiding device on a label paper production line disclosed in the authorization announcement number CN209871862U, which includes a device body, a base, side panels and movable rollers, one end of the device body is placed in contact with the production line, and a raw material roller is provided at the end of the device body away from the production line, on which label paper is wound, and a first feeding roller is provided at the end of the production line away from the device body, and a side panel is fixedly connected to the top of the base, and the side panels are provided in two groups, and the planes where the two groups of side panels are located are parallel, and the two groups of side panels are arranged in parallel. A second feeding roller, a movable roller, etc. are respectively installed between the plates. Through the coordinated use of the first limit plate, the first screw rod, the second limit plate and the second screw rod, the label paper will not shift during the transportation process, thereby realizing the guiding function of the device. In this technical solution, the label paper tape is mainly pressurized by the design of the first pressure roller and the second pressure roller to reduce its vibration. However, the action position of the first pressure roller is relatively fixed. When facing changes in production line speed or label paper tapes of different thickness specifications, the pressure roller in a fixed position is difficult to fully adapt to the changing needs. When multiple pressure rollers are arranged continuously, it is difficult for multiple pressure rollers to move together, so that the paper tape cannot be stably pressed along the line.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides an embodiment: a support and guiding device on a label paper production line, comprising a back plate 1 and a right angle seat 2 fixed at one end of the back plate 1 surface, and a wiring ramp 3 is fixed on the outer wall of the right angle seat 2 on the side away from the back plate 1, and a flat plate 4 is fixed at one end of the wiring ramp 3, and the flat plate 4 is in a horizontal state. A steel roller 8 is installed on the surface of the back plate 1 on one side of the wiring ramp 3, and a plurality of equally spaced driven shafts 6 are rotatably installed on the surface of the back plate 1 above the flat plate 4, and a driving shaft 5 is rotatably installed on the surface of the back plate 1 on one side of the driven shaft 6, and a paper tape pressing member 7 is installed at one end of the driving shaft 5 and the driven shaft 6 away from the back plate 1, and the paper tape pressing member 7 at the end of the driving shaft 5 and the driven shaft 6 is pressed on the upper surface of the label paper tape, and a pulley transmission structure 14 for maintaining power connection is installed at the other end of the driving shaft 5 and the driven shaft 6, and an elastic reset structure 13 for preventing the driving shaft 5 from rotating is provided on the back of the back plate 1;

[0019] An unwinding disk 9 is rotatably mounted on one end of the surface of the back plate 1, and an elastic clamping structure 12 and a feeding roller 10 are mounted on the surface of the back plate 1 under the unwinding disk 9. A gap for the paper tape to pass through is provided between the elastic clamping structure 12 and the feeding roller 10. The paper tape passes between the elastic clamping structure 12 and the feeding roller 10 and under the steel roller 8, and the paper tape covers the upper surface of the routing inclined plate 3 and the flat plate 4.

[0020] A double-pulley drive assembly 11 for driving the unwinding disk 9 and the feeding roller 10 to rotate is installed at one end of the surface of the back plate 1. The double-pulley drive assembly 11 includes a servo motor installed at one end of the surface of the back plate 1, and a belt transmission structure for connecting the unwinding disk 9 and the feeding roller 10 installed at the output end of the servo motor. The staff can start the double-pulley drive assembly 11 to work. The servo motor in the double-pulley drive assembly 11 drives the unwinding disk 9 and the feeding roller 10 to rotate synchronously through two belt transmission structures. In this process, the unwinding speed of the unwinding disk 9 can be adapted to the traction speed of the label paper tape under the control of the double-pulley drive assembly 11;

[0021] The elastic clamping structure 12 comprises a U-shaped frame 1201 fixed to one end of the surface of the back plate 1, a round-shaped slide 1202 slidably mounted on the front and rear outer walls of the U-shaped frame 1201, a rubber roller 1203 rotatably mounted between the two round-shaped slides 1202, and a protruding tongue 1204 fixed to the front and rear outer walls of the U-shaped frame 1201, one end of the protruding tongue 1204 penetrates to the outside of the round-shaped slide 1202, a second spring 1205 is mounted on one side outer wall of the protruding tongue 1204, one end of the second spring 1205 is fixedly connected to one side inner wall of the round-shaped slide 1202, when the label paper tape passes between the elastic clamping structure 12 and the feeding roller 10, the elastic force of the second spring 1205 will force the round-shaped slide 1202 and the rubber roller 1203 to approach the feeding roller 10, so that the label paper tape is clamped by the rubber roller 1203 and the feeding roller 10;

[0022] The elastic reset structure 13 includes an arc-shaped groove 1301 arranged on one side of the back of the back plate 1, and a rear swing arm 1302 fixed to one end of the driving shaft 5, a convex column is fixed to one end of the rear swing arm 1302, one end of the convex column extends to the inside of the arc-shaped groove 1301, a coil spring 1303 is installed inside the arc-shaped groove 1301, the top of the coil spring 1303 and the bottom of the convex column abut against each other, the arc-shaped groove 1301 and the driving shaft 5 are concentric, and the paper tape pressing member 7 includes a front swing arm 701 fixed to one end of the driving shaft 5, and a sponge roller 702 rotatably installed on the front and rear inner walls of the front swing arm 701;

[0023] The driving shaft 5 and the driven shaft 6 are kept in a synchronous and same-direction rotation state through the pulley transmission structure 14. When one of the driven shafts 6 and the paper tape clamping piece 7 rotates and deflects, the driving shaft 5 rotates driven by the driven shaft 6 and the pulley transmission structure 14, and then the driving shaft 5 drives the rear swing arm 1302 to swing clockwise. At this time, the coil spring 1303 is in a compressed state. The reaction force of the coil spring 1303 is used to always force the sponge roller 702 to press on the label paper tape, so that the paper tape clamping piece 7 can quickly return to the optimal working state when subjected to external impact or sudden changes in the label paper tape, thereby maintaining the constancy and stability of the pressure.

[0024] When the embodiment of the present application is in use, the staff first puts the label paper roll to be unwound on the unwinding disk 9, and then makes the paper tape on the label paper roll pass through the elastic clamping structure 12, the feed roller 10, and the bottom of the steel roller 8, and makes the paper tape cover the upper surface of the routing ramp 3 and the flat plate 4. At this time, the paper tape is initially clamped by the elastic clamping structure 12 and the feed roller 10, and the steel roller 8 tensions the label paper tape. Finally, the routing ramp 3 and the flat plate 4 support and guide the label paper tape. During this process, the paper tape pressing member 7 at the end of the active shaft 5 and the driven shaft 6 will be pressed on the upper surface of the label paper tape. When the external production equipment pulls the label paper tape, the paper tape pressing member 7 can be deflected with the central axis of the active shaft 5 or the driven shaft 6 as the center of the circle, and because the active shaft 5 and the driven shaft 6 are connected by the pulley transmission structure 14 When power connection is performed, the elastic reset structure 13 can always force the paper tape clamping member 7 to press on the upper surface of the label paper tape, thereby reducing the vibration of the label paper tape during traction and unwinding. The structural design of the paper tape clamping member 7 swinging around the active shaft 5 or the driven shaft 6 as the central axis can achieve effective compression of label paper tapes of different thickness specifications, allowing the clamping member to automatically adjust the pressure and contact angle according to the thickness of the label paper tape, ensuring that the label paper tape passes through the production line stably and without fluctuations during transmission. At the same time, the elastic reset structure 13 and the pulley transmission structure 14 enable the active shaft 5 and multiple driven shafts 6 as well as the paper tape clamping member 7 to work together, balance the tension distribution of the label paper tape during transmission, reduce the vibration or deviation of the label paper tape caused by uneven tension, and ensure the smoothness and stability of the production line operation.
