[0002] A rewinder is a mechanical device used to rewind films, tapes or toilet paper wound on large rolls onto small rolls. Rewinders are mainly used in the preparation of products such as toilet paper rewinding, tape rewinding, plastic film rewinding, etc. The process of rewinding tape paper on a rewinder mainly involves feeding, rewinding, cutting, labeling and discharging.

[0003] However, in the existing rewinding machine, the speed of the unwinding shaft and the rewinding shaft is constant during the rewinding process. As the rewinding operation proceeds, the diameter of the tape roll on the unwinding shaft and the rewinding shaft changes, resulting in changes in the tension of the tape during rewinding, which can easily affect the compactness of the tape rewinding. Therefore, it is urgent to design a high-precision tape rewinding machine to solve the above problems. Utility Model Content

[0026] The utility model provides Figure 1-5 A high-precision tape rewinding machine as shown in the figure comprises:

[0027] The rewinding machine body 100 includes a base 101, a side plate 102 and a top plate 103, and a mounting groove 1021 is provided on one side of the side plate 102;

[0028] The feeding mechanism 200 includes a feeding air expansion shaft 201 arranged on one side of the side plate 102, a guide roller 202, and a motor 203 arranged on the other side of the side plate 102 and connected to the feeding air expansion shaft 201. The feeding air expansion shaft 201 is driven to rotate by the motor 203, so that the tape mother roll on the feeding air expansion shaft 201 can be unloaded;

[0029] The rewinding mechanism 300 includes a turntable 301 movably sleeved in the mounting groove 1021, a receiving air-expanding shaft 302 movably connected to one side of the turntable 301, a second motor 303 fixedly connected to the other side of the turntable 301 and transmission-connected to the receiving air-expanding shaft 302, and a third motor 305 fixedly connected to one side of the side plate 102. A connecting shaft 304 is fixedly connected to the center of one side of the turntable 301. One end of the connecting shaft 304 is connected to the output shaft of the third motor 305 through a coupling. The second motor 303 drives the receiving air-expanding shaft 302 to rotate, so as to rewind the adhesive tape. The third motor 305 drives the turntable 301 to rotate 180°. After the two receiving air-expanding shafts 302 are interchanged, the adhesive tape between the two receiving air-expanding shafts 302 is cut by a cutter, so that the two receiving air-expanding shafts 302 can be rewound alternately, which is beneficial to improving the rewinding efficiency.

[0030] The adjustment mechanism 400 includes a display screen 401 and a function button 402 arranged on one side of the base 101, a mounting plate 403 and an infrared rangefinder 404 arranged on one side of the side panel 102, and a mounting box 405 arranged on the lower surface of the top panel 103, a clamping roller 406 is provided at the bottom of the mounting box 405, and an electric telescopic rod 407 fixedly connected to the mounting box 405 is provided on the upper surface of the top panel 103.

[0031] In addition, the base 101, the side panel 102 and the top panel 103 are designed as an integrated unit and have a U-shaped structure. An inclined surface is provided on one side of the base 101, and the display screen 401 and the function button 402 are arranged at both ends of the inclined surface, which is convenient for observing the operation of each component and also convenient for inputting control instructions through the function button 402.

[0032] Specifically, two of the collecting air-inflating shafts 302 and the motor 2 303 are provided, and the two motors 2 303 can drive the two collecting air-inflating shafts 302 to operate independently, and the central axis surfaces of the two collecting air-inflating shafts 302 and the clamping roller 406 coincide with each other, ensuring that when the upper collecting air-inflating shaft 302 is performing a rewinding operation, the clamping roller 406 can compact the tape on the collecting air-inflating shaft 302.

[0033] It is worth mentioning that there are two infrared rangefinders 404. The upper infrared rangefinder 404 coincides with the central axis of the upper receiving air expansion shaft 302 and the guide roller 202, and the lower infrared rangefinder 404 coincides with the central axis of the feeding air expansion shaft 201, which is convenient for real-time monitoring of the radius of the tape roll on the upper receiving air expansion shaft 302 and the feeding air expansion shaft 201. Before monitoring, the radius of the receiving air expansion shaft 302 and the feeding air expansion shaft 201 is measured first, and then the infrared rangefinder 404 and the corresponding The distance between the receiving air expansion shaft 302 and the feeding air expansion shaft 201 is defined as a and b. During the rewinding operation, the distance between the infrared rangefinder 404 and the corresponding tape rolls on the receiving air expansion shaft 302 and the feeding air expansion shaft 201 is measured respectively, and the distance between the infrared rangefinder 404 and the corresponding tape rolls on the receiving air expansion shaft 302 and the feeding air expansion shaft 201 is defined as A and B. The sum of the absolute value of the difference between a and A and the radius of the receiving air expansion shaft 302 is the radius of the tape roll on the receiving air expansion shaft 302, and the sum of the absolute value of the difference between b and B and the radius of the feeding air expansion shaft 201 is the radius of the tape roll on the feeding air expansion shaft 201.

[0034] Specifically, symmetrical movable grooves 4051 are provided at both ends of the installation box 405, and springs 4052 are provided in the movable grooves 4051. When the radius of the tape on the receiving air-expanding shaft 302 gradually increases, the clamping roller 406 can be pushed upward to ensure that the receiving air-expanding shaft 302 can rotate normally during rewinding.

[0035] It should be noted that a PLC (programmable logic controller) is provided in the base 101, which is electrically connected to the feeding air expansion shaft 201, motor 1 203, receiving air expansion shaft 302, motor 2 303, motor 305, display screen 401, function button 402, infrared rangefinder 404 and electric telescopic rod 407, so as to facilitate the unified control of the operation of various electrical appliances through the PLC.

[0036] Specifically, the guide roller 202 and the pressure roller 406 are both rubber rollers, which can effectively prevent the tape from being damaged during the rewinding process.

[0037] Working principle: When the high-precision tape rewinder is used, firstly, the radius of the feeding air-expansion shaft 201 and the receiving air-expansion shaft 302 and the distance between the infrared rangefinder 404 and the feeding air-expansion shaft 201 and the receiving air-expansion shaft 302 are measured, and then the measured original data is entered into the rewinder body 100, and then the mother roll of tape is sleeved on the feeding air-expansion shaft 201, and the tape is guided by the guide roller 202 and then wound around the receiving air-expansion shaft 302, and then the electric telescopic rod 407 is started, and the electric telescopic rod 407 drives the installation box 405 to move downward until the clamping roller 406 fits with the receiving air-expansion shaft 302. The high-precision tape rewinder has an advanced design, a compact structure and is easy to use. By setting an infrared rangefinder 404, the radius of the tape roll on the feeding air expansion shaft 201 and the receiving air expansion shaft 302 can be monitored in real time. The rotation speed of the motor 2 303 is set to a constant value. By changing the rotation speed of the motor 1 203, the linear speed of the tape roll on the feeding air expansion shaft 201 and the receiving air expansion shaft 302 can be made the same, ensuring that the tension of the tape remains unchanged during operation. By setting an electric telescopic rod 407, an installation box 405 and a clamping roller 406, the tape roll on the receiving air expansion shaft 302 can be compacted, which can improve the compactness of the tape rewinding.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
