Description

Technical Field

[0001] This utility model relates to the field of label paper production technology, specifically a label rewinding mechanism. Background Technology

[0002] The label rewinder is the final step in the label paper production line. After the label paper is printed by the printer, it is discharged through the print head and enters the rewinder. At this time, the rewinding mechanism works to collect and store the printed labels. The label rewinder is usually used in conjunction with the printer, so it is necessary to ensure that the speed of the label rewinder and the printer are consistent and that the rewinder can start and stop with the printer.

[0003] However, traditional label rewinding machines are not convenient to adjust the winding state according to changes in roll diameter or fluctuations in media tension during use. When the diameter of the label roll gradually increases or printing stops, tension imbalance is easily caused, resulting in damage to the printer head. Utility Model Content

[0004] The purpose of this invention is to provide a label rewinding mechanism that solves the problem that traditional label rewinding machines are not easy to adjust the rewinding state according to changes in roll diameter or fluctuations in media tension during use. When the diameter of the label roll gradually increases or printing stops, tension imbalance is easily caused, resulting in damage to the printer head.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a label rewinding mechanism, including a housing, on which a winding assembly and a tension detection assembly are installed. The winding assembly winds up the label paper, and the tension detection assembly detects the force on the label paper during the winding process. A support rod is installed on the surface of the housing, and the support rod is located on the opposite side of the winding assembly and the tension detection assembly to support the label paper.

[0006] As a preferred embodiment of the label rewinding mechanism of this utility model, a limiting sleeve is installed on the surface of the support rod, and the label paper is located on the surface of the limiting sleeve and is movably connected to it to prevent the label paper from shifting during the rewinding process.

[0007] As a preferred embodiment of the label rewinding mechanism of this utility model, the winding assembly includes a winding rod and a stepper motor. The winding rod is rotatably connected to the housing, and one end of the winding rod extends to the outside of the housing and is fitted with an anti-slip sleeve.

[0008] In a preferred embodiment of the label rewinding mechanism of this utility model, the output shaft of the stepper motor is equipped with a first driving wheel, the surface of the winding rod is sleeved with a first driven wheel, and the surfaces of the first driving wheel and the first driven wheel are connected by a first belt.

[0009] As a preferred embodiment of the label rewinding mechanism of this utility model, the stepper motor is fixedly connected to a motor base at its bottom, and the motor base is installed on the bottom of the inner wall of the housing.

[0010] As a preferred embodiment of the label rewinding mechanism of this utility model, the tension detection component includes a rotating rod and an angle potentiometer. The rotating rod is rotatably connected to the housing. One end of the rotating rod extends to the outside of the housing and is fitted with a swing arm. A swing rod is installed at the end of the swing arm away from the rotating rod.

[0011] In a preferred embodiment of the label rewinding mechanism of this utility model, a detection shaft is installed at the detection end of the angle potentiometer, a second driving wheel is sleeved on the detection shaft, a second driven wheel is sleeved on the surface of the rotating rod, and a second belt is drivingly connected to the surfaces of the second driving wheel and the second driven wheel.

[0014] As a preferred embodiment of the label rewinding mechanism of this utility model, the bottom four corners of the housing are fixedly installed with support legs.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves real-time monitoring and automatic adjustment of the tension during label paper winding by setting the winding assembly and tension detection assembly to work together. The tension detection assembly uses a swing rod and swing arm to sense changes in the force of the label paper, and drives the detection shaft of the angle potentiometer to rotate through the rotating rod, converting the mechanical swing into an electrical signal that is fed back to the control module. The control module judges the current tension state based on the swing angle detected by the angle potentiometer and dynamically adjusts the speed of the stepper motor. When the tension is too high, the winding speed is reduced; when the tension abnormally rises to the preset upper limit, the winding stops. This effectively avoids problems such as label paper stretching and deformation, breakage, or printhead damage caused by excessive tension, and improves the stability of equipment operation and label winding quality.

[0016] 2. This utility model effectively guides and laterally limits the label paper entering the winding area by setting a limiting sleeve on the surface of the support rod, preventing the label from deviating during winding. The winding rod is equipped with an anti-slip sleeve to enhance the friction between it and the label paper, ensuring smooth winding without slippage. The whole machine has a compact structure, and the shell and cover protect the internal transmission components. The support legs provide stable support, and the control module is integrated and installed on the cover, which is convenient for maintenance and wiring. This solution not only improves the level of automation control, but also enhances the reliability and service life of the equipment, and is suitable for use with high-precision label printing equipment.

[0024] Please see Figures 1-5 A label rewinding mechanism includes a housing 1, on which a winding assembly 2 and a tension detection assembly 3 are mounted. The winding assembly 2 winds up the label paper, and the tension detection assembly 3 detects the force on the label paper during the winding process.

[0025] Furthermore, a support rod 4 is installed on the surface of the housing 1. The support rod 4 is located on the opposite side of the winding assembly 2 and the tension detection assembly 3 to support the label paper.

[0026] Furthermore, a limiting sleeve 5 is installed on the surface of the support rod 4, and the label paper is located on the surface of the limiting sleeve 5 and is movably connected to it to prevent the label paper from shifting during the winding process.

[0027] Furthermore, the winding assembly 2 includes a winding rod 201 and a stepper motor 204. The winding rod 201 is rotatably connected to the housing 1, and one end of the winding rod 201 extends to the outside of the housing 1 and is fitted with an anti-slip sleeve 202.

[0028] Furthermore, the output shaft of the stepper motor 204 is equipped with a first drive wheel 205, and the surface of the winding rod 201 is fitted with a first driven wheel 207. The surfaces of the first drive wheel 205 and the first driven wheel 207 are connected by a first belt 206.

[0029] Furthermore, a motor mount 203 is fixedly connected to the bottom of the stepper motor 204, and the motor mount 203 is installed on the bottom of the inner wall of the housing 1.

[0030] Furthermore, the tension detection assembly 3 includes a rotating rod 301 and an angle potentiometer 304. The rotating rod 301 is rotatably connected to the housing 1. One end of the rotating rod 301 extends to the outside of the housing 1 and is fitted with a swing arm 302. A swing rod 303 is installed at the end of the swing arm 302 away from the rotating rod 301.

[0031] Furthermore, a detection shaft 309 is installed on the detection end of the angle potentiometer 304, a second driving wheel 306 is sleeved on the detection shaft 309, a second driven wheel 308 is sleeved on the surface of the rotating rod 301, and a second belt 307 is connected to the surfaces of the second driving wheel 306 and the second driven wheel 308 for transmission.

[0032] Furthermore, a plate 305 is fixedly connected to the angle potentiometer 304. The plate 305 is installed at the bottom of the inner wall of the housing 1, and the detection shaft 309 is connected to the plate 305 through a bearing.

[0033] Furthermore, the top of the housing 1 is provided with a cover 6, which protects the components inside the housing 1. A control module 7 is fixedly installed on the cover 6. The control module 7 is electrically connected to the winding assembly 2 and the tension detection assembly 3 to control the winding process.

[0034] Furthermore, support legs 8 are fixedly installed at the four corners of the bottom of the housing 1, and the support legs 8 provide stable support for the bottom of the housing 1.

[0035] After the printer finishes printing the label, the rewind assembly 2 rewinds the label. During the rewinding process, the label is wrapped around the bottom of the tension detection assembly 3 and the top of the support rod 4. The limiting sleeve 5 limits the label on the support rod 4 to prevent it from shifting during the rewinding process. As the rewind assembly 2 rewinds, the label is wrapped around the surface of the rewind assembly 2 to form a label roll. As the roll increases, the rewinding tension of the label increases and drives the swing rod 303 and swing arm 302 of the tension detection assembly 3 to swing. The angle potentiometer 304 on the tension detection assembly 3 detects the swing angle. The larger the swing angle, the greater the tension. The rewinding speed of the rewind assembly 2 is controlled according to the swing angle. When the tension increases, the rewinding speed is reduced to prevent damage to the label paper and the print head. When printing stops, the tension reaches the highest preset value, and the rewind assembly 2 is controlled to stop rewinding.

[0036] During the operation of the winding assembly 2, the stepper motor 204 controls the rotation of the winding rod 201 through the first driving wheel 205, the first belt 206 and the first driven wheel 207. The winding rod 201 winds up the label paper. The anti-slip sleeve 202 is fitted on the surface of the winding rod 201 to increase the surface friction of the winding rod 201 and prevent slippage during the winding process.

[0037] During the operation of the tension detection component 3, the label paper is wound around the bottom of the swing rod 303. When the tension of the label paper fluctuates, the swing rod 303 and the swing arm 302 drive the rotating rod 301 to rotate. The rotating rod 301 drives the detection shaft 309 to rotate through the second driven wheel 308, the second belt 307 and the second driving wheel 306. The angle potentiometer 304 detects the rotation angle of the detection shaft 309 and transmits the detection data to the control module 7. The control module 7 adjusts the working state of the stepper motor 204 according to the detection angle, reducing the speed of the stepper motor 204 or controlling the stepper motor 204 to stop working.
