Description

Technical Field

[0001] The invention relates to the technical field of release paper, and in particular to a release paper rewinding device. Background Art

[0002] Release refers to the process of separating materials from substrates, which is commonly seen in the production of tapes, labels and other products. Release paper is a special paper with a release agent coated on the surface to prevent sticky materials from sticking and facilitate subsequent use.

[0003] Release paper rewinding is the process of rewinding release paper into a roll. It is usually used to adjust the length and width of the paper or repair defects in the roll to meet different production needs. During the rewinding process, parameters such as tension and speed must be controlled to ensure that the roll is flat and free of bubbles or wrinkles. Release paper rewinding is widely used in packaging, printing, electronics and other industries, and is an important link in improving production efficiency and product quality.

[0004] The traditional device uses an unwinding drum as the unwinding mechanism. When wrinkles appear during rewinding, the unwinding needs to be paused, and the unwinding is mostly driven by the driving motor of the rewinding drum through tension to drive the unwinding drum to rotate and unwind. When the motor of the rewinding drum is paused, the unwinding drum is prone to continue rotating due to inertia, resulting in excessive accumulation of unwound material and aggravated wrinkles. Using a resistance device to limit the unwinding of the unwinding drum can effectively prevent the phenomenon of excessive unwinding caused by inertia. However, there is also a problem of excessive resistance, which causes the release paper to be tight and then causes vertical wrinkles, and may also cause the release paper to break. Summary of the invention

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Example

[0024] Reference Figure 1-Figure 6 A release paper rewinding device comprises a workbench 1, and also comprises: an unwinding component 2, which is fixedly mounted on one side of the workbench 1 and performs a release paper unwinding action, wherein the unwinding component 2 comprises a support frame 203, and an insertion rod 204 rotatably mounted on the support frame 203 is externally sleeved with a roller 205 with the release paper rolled up and plugged in; a rewinding component 3, which is fixedly mounted on the other side of the workbench 1 and performs a release paper rewinding action, wherein the rewinding component 3 is transmitted through the release paper, and when the release paper is rewound, the rewinding component 3 drives the unwinding component 2 to act synchronously; a variable resistance component 9, wherein a rotating shaft 903 of the variable resistance component 9 fixed on one side of the support frame 203 is plugged into the insertion rod 204, and the variable resistance component 9 is controlled by electricity to change its own electromagnetic resistance to the rotating shaft 903, and performs an adjustable variable resistance action.

[0025] The above-mentioned release paper rewinding device effectively solves the problem of excessive unwinding and wrinkles caused by inertia in the rewinding process of the traditional device through the coordinated work of the unwinding component 2, the rewinding component 3 and the variable resistance component 9; Specifically, the unwinding assembly 2 includes a support frame 203 and an insertion rod 204, and a roller 205 for winding the release paper is sleeved on the insertion rod 204. The unwinding assembly 3 drives the unwinding assembly 2 to move synchronously through the transmission of the release paper, and the variable resistance assembly 9 adjusts the rotation resistance of the unwinding drum through electromagnetic resistance to prevent excessive unwinding due to inertia. When the winding component 3 starts working, the tension of the release paper drives the unwinding drum to rotate. At the same time, the variable resistance component 9 adjusts the electromagnetic resistance according to real-time needs to ensure that the rotation speed of the unwinding drum is synchronized with the winding speed to avoid excessive material discharge due to inertia. When the winding component 3 is paused, the variable resistance component 9 quickly increases the resistance to prevent the unwinding drum from continuing to rotate, thereby preventing the release paper from accumulating and wrinkling. In addition, the resistance of the variable resistance component 9 is adjustable to avoid the problem of tightness or breakage of the release paper due to excessive resistance. Through this electrically controlled variable resistance mechanism, the equipment achieves precise synchronization of unwinding and winding, ensures the flatness and quality of the release paper during the rewinding process, and effectively solves the technical problems in traditional devices. The user electrically connects the electromagnet 902 to the computer control board to control the magnetic force of the electromagnet 902.

[0026] In this embodiment, the variable resistance assembly 9 includes a support plate 901, which is fixedly mounted on one side of the support frame 203 through a third screw 907. A plurality of electromagnets 902 are fixedly mounted in the upper cavity of the support plate 901, and the plurality of electromagnets 902 are arranged in a circumferentially uniform array in the upper cavity of the support plate 901. In order to realize the electrically controlled variable resistance, the outside of the rotating shaft 903 rotatably mounted on one side of the support frame 203 is respectively mounted with contact plates 904 through two second screws 906, and the two contact plates 904 are formed with sleeves, and a plurality of magnetic disks 905 are respectively fixedly mounted on the outside of each contact plate 904, and the magnetic disks 905 are evenly arranged on the outside of the sleeve in the circumferential direction, and the magnetic disks 905 are magnetically connected with the electromagnets 902 to perform a magnetic repulsion action.

[0027] The variable resistance component 9 realizes precise control of the rotation resistance of the unwinding drum through electromagnetic force regulation, thereby solving the inertial unwinding and wrinkle problems during the rewinding process of the release paper; Specifically, the support plate 901 of the variable resistance assembly 9 is fixed to one side of the support frame 203 by a third screw 907, a plurality of electromagnets 902 are evenly installed in the circumferential direction in the upper cavity of the support plate 901, a rotating shaft 903 is rotatably installed on one side of the support frame 203, and a contact plate 904 is installed on the outside thereof by two second screws 906, the contact plate 904 is formed into a sleeve structure, and a plurality of magnetic disks 905 are fixed on the outside of the sleeve in the circumferential direction; When the equipment is running, the electromagnet 902 generates a magnetic field after being energized, and forms a magnetic repulsion effect with the magnetic disk 905, thereby applying resistance to the rotating shaft 903. By adjusting the current intensity of the electromagnet 902, the magnitude of the magnetic force can be changed, thereby realizing dynamic adjustment of the resistance of the rotating shaft 903. When the winding component 3 drives the release paper to rewind, the variable resistance component 9 adjusts the current of the electromagnet 902 in real time according to the rotation speed of the unwinding drum and the tension requirement of the release paper, so that the magnetic repulsion between the magnetic disk 905 and the electromagnet 902 reaches the best balance, which prevents the unwinding drum from continuing to rotate due to inertia and causing excessive material discharge, and avoids excessive resistance causing the release paper to be tight or broken. This electrically controlled variable resistance mechanism realizes the intelligent adjustment of the rotation resistance of the unwinding drum, ensures the smooth transmission of the release paper during the rewinding process, and effectively solves the wrinkle problem caused by inertial discharge and uneven resistance in traditional devices.

[0028] In order to realize the rapid disassembly, assembly and replacement of the roller 205, the plug rod 204 is pluggable and installed on the support frame 203, and a flange 206 is rotatably installed on one side of the plug rod 204. The flange 206 is fixedly installed on one side of the support frame 203 through a first screw 207. In order to realize the support of the roller 205 and the installation and replacement of the auxiliary roller 205, the unwinding assembly 2 further includes an elevator 201, which is fixedly installed on the workbench 1, and the support frame 203 is fixedly installed on the main body of the elevator 201. The upper part of the elevator part of the elevator 201 is fixedly installed with an arc plate 202 for contacting and supporting the roller 205 with the release paper rolled up.

[0029] In order to realize the rapid disassembly, installation and replacement of the roller 205, the release paper rewinding device adopts the coordinated design of the insertion rod 204, the flange 206 and the elevator 201, which significantly improves the efficiency of installing and replacing the roller 205; When installing or replacing the roller 205, first disassemble the first screw 207 that fixes the flange 206, remove the flange 206 from the support frame 203, and then pull out the plug 204. At this time, the lift 201 is started, and the arc plate 202 on the upper part of its lifting part is controlled to rise to a suitable height to provide support for the placement of the roller 205. The special forklift stably places the roller 205 with the release paper on the two arc plates 202 to ensure that the roller 205 is aligned with the support frame 203. Then, the operator reinserts the plug 204 into the center hole of the roller 205 and passes it through the support frame 203 to firmly connect the roller 205 with the plug 204. Finally, the flange 206 is fixed back to one side of the support frame 203 by the first screw 207 to ensure the stability of the plug 204 and the roller 205. Through the above steps, the equipment realizes the rapid disassembly, assembly and replacement of the roller 205, reducing downtime. At the same time, the design of the lift 201 and the curved plate 202 provides precise support for the installation of the roller 205, avoiding errors and safety hazards in manual operation, and significantly improving the operating efficiency and safety of the equipment.

[0030] In order to realize the electric control rewinding and guiding of release paper, preferably, a motor 8 is fixedly installed on the side of the support frame 203 close to the unwinding assembly 2. The unwinding assembly 2 and the winding assembly 3 have the same structure. The output end of the motor 8 is connected to the insertion rod 204 of the winding assembly 3 for transmission. The first guide roller 4 is rotatably installed on the side of the workbench 1 close to the unwinding assembly 2, and the second guide roller 5 is rotatably installed on the side of the workbench 1 close to the winding assembly 3. In order to further control the tension degree of the release paper during transmission, a tensioning roller 6 is further provided between the second guide roller 5 and the second guide roller 5. When the release paper is rewound, it is drawn out from the unwinding assembly 2 and passes through the lower part of the first guide roller 4, the upper part of the tensioning roller 6 and the lower part of the second guide roller 5 in sequence, and then is wound on the winding assembly 3. In order to realize the electrically controlled lifting and lowering of the tensioning roller 6, further, electric push rods 7 are fixedly installed on both sides of the workbench 1, and each electric push rod 7 is fixedly connected to a support seat 14 on the upper part. The tensioning roller 6 is rotatably installed inside the two support seats 14, and the workbench 1 is provided with a guide channel for lifting and lowering the tensioning roller 6.

[0031] Through the coordinated work of the motor 8, the guide roller and the tension roller 6, the release paper is rewound efficiently, accurately and stably, effectively solving the wrinkle and breakage problems caused by inertial feeding and uneven tension in the traditional device. A motor 8 is fixedly installed on one side of the support frame 203 close to the unwinding assembly 2, and the output end of the motor 8 is connected to the insertion rod 204 of the winding assembly 3, and the winding assembly 3 is driven to rotate through the transmission system, and the tension of the release paper is used to drive the unwinding assembly 2 to rotate synchronously, so as to realize the continuous transmission of the release paper from the unwinding assembly 2 to the winding assembly 3; In order to ensure that the release paper remains flat during the transmission process, the equipment installs a first guide roller 4 on the side of the workbench 1 close to the unwinding component 2, and installs a second guide roller 5 on the side close to the winding component 3. After the release paper is drawn out from the unwinding component 2, it passes through the lower part of the first guide roller 4, the upper part of the tensioning roller 6, and the lower part of the second guide roller 5 in sequence, and is finally wound on the winding component 3. The rotating installation design of the first guide roller 4 and the second guide roller 5 reduces the friction between the release paper and the roller surface, avoids the surface damage of the release paper, and ensures that the release paper is always in the correct position during the transmission process to prevent deviation or distortion. In order to further control the tension of the release paper during the transmission process, the equipment is provided with a tensioning roller 6 between the first guide roller 4 and the second guide roller 5. The tensioning roller 6 is height-adjusted by the electric-controlled lift 201, thereby changing the tension of the release paper; Specifically, electric push rods 7 are fixedly installed on both sides of the workbench 1, and a support seat 14 is fixedly connected to the upper part of each electric push rod 7. The tensioning rollers 6 are rotatably installed inside the two support seats 14. A guide channel is opened on the workbench 1 to guide the lifting movement of the tensioning rollers 6; When the electric push rod 7 is started, the support seat 14 drives the tension roller 6 to move up and down along the guide channel, so as to adjust the tension of the release paper: when the electric push rod 7 pushes the tension roller 6 to rise, the path of the release paper is elongated and the tension is increased, which is suitable for the situation that the release paper is relatively loose, and can effectively avoid wrinkles or accumulation caused by insufficient tension; when the electric push rod 7 pulls the tension roller 6 down, the path of the release paper is shortened and the tension is reduced, which is suitable for the situation that the release paper is too tight, and can prevent the release paper from breaking or deformation due to excessive tension; The height of the tensioning roller 6 can be dynamically adjusted according to real-time needs through electric lifting, ensuring that the release paper always maintains appropriate tension during the transmission process, thereby avoiding quality problems caused by uneven tension; The specific working process is divided into a starting stage, a transmission stage, a tension adjustment stage and a completion stage: in the starting stage, the motor 8 drives the winding component 3 to start rotating, and at the same time drives the unwinding component 2 to rotate synchronously through the tension of the release paper; in the transmission stage, the release paper is led out from the unwinding component 2, passes through the first guide roller 4, the tensioning roller 6 and the second guide roller 5 in sequence, and is finally wound on the winding component 3; in the tension adjustment stage, the equipment adjusts the height of the tensioning roller 6 in real time through the electric push rod 7 to ensure that the tension of the release paper is always in the best state; in the completion stage, when the release paper is completely wound, the motor 8 stops running and the equipment enters the standby state, realizing the high efficiency, precision and stability of the release paper rewinding process, significantly improving the production quality and efficiency, and solving the technical problems existing in traditional devices.

[0032] In order to realize that the exhaust fan 12 can be synchronously driven to rotate and exhaust when the unwinding assembly 2 is unwinding, preferably, one end of the rotating shaft 903 is also fixedly connected to a linkage rod 11, and one end of the linkage rod 11 away from the rotating shaft 903 is fixedly connected to the exhaust fan 12, and the air outlet pipe 10 fixed to one side of the support frame 203 is sleeved on the outside of the linkage rod 11 and the exhaust fan 12, and the exhaust fan 12 is located at the air outlet of the air outlet pipe 10. In order to extract the gas from the first guide roller 4 through the exhaust fan 12 and perform a vacuum operation on the release paper passing through the first guide roller 4, further, one end of the air outlet pipe 10 is rotatably connected and penetrated with the first guide roller 4 through the transmission pipe 13, the first guide roller 4 is hollow, and the first guide roller 4 is provided with an air suction gap for cleaning the release paper.

[0033] Through the coordinated design of the linkage rod 11, the exhaust fan 12 and the air outlet pipe 10, the synchronous exhaust and release paper dust collection functions are realized during the unwinding process, which effectively solves the problem of release paper surface contamination and reduced equipment operation efficiency caused by dust accumulation in traditional devices; When the unwinding assembly 2 is unwinding, the linkage rod 11 fixedly connected to one end of the rotating shaft 903 rotates synchronously with the rotating shaft 903, and an exhaust fan 12 is fixedly installed at one end of the linkage rod 11 away from the rotating shaft 903. The exhaust fan 12 is located at the air outlet of the air outlet pipe 10 on one side of the support frame 203. When the rotating shaft 903 drives the linkage rod 11 to rotate, the exhaust fan 12 rotates accordingly. In order to clean the release paper during the transmission process, one end of the air outlet pipe 10 is rotatably connected and connected with the first guide roller 4 through the transmission pipe 13. The first guide roller 4 adopts a hollow design, and an air suction gap for dust collection is opened on its outside; When the exhaust fan 12 is working, the negative pressure generated is transmitted to the inside of the first guide roller 4 through the transmission pipe 13, so that the suction gap outside the first guide roller 4 forms a suction force, and the dust and impurities on the surface of the release paper passing through the first guide roller 4 are sucked into the first guide roller 4, and discharged to the outside of the equipment through the transmission pipe 13 and the air outlet pipe 10; This design uses the negative pressure of the exhaust fan 12 to vacuum and clean the surface of the release paper, ensuring the cleanliness and quality of the release paper during the rewinding process. Through the coordinated work of the linkage rod 11, the exhaust fan 12 and the exhaust pipe 10, the equipment achieves efficient exhaust and dust collection functions during the unwinding process, significantly improving the operating efficiency of the equipment and the product quality of the release paper.
