Description

Technical Field

[0001] This utility model relates to the field of label winding, and more particularly to a thermal self-adhesive label winding device. Background Technology

[0002] Thermal self-adhesive labels are special labels that use a thermal coating to develop color when heated to record information. They are widely used in logistics, retail, and medical industries due to their ease of printing and lack of the need for ribbons. The final crucial step after manufacturing and slitting is rewinding. Proper rewinding ensures that the labels remain flat, secure, and wrinkle-free during transportation, storage, and subsequent high-speed automatic labeling, which is essential for guaranteeing product quality and reliability.

[0003] As disclosed in announcement number CN217577650U, a self-adhesive label winding device adjusts the distance between the roller and the winding drum by activating an electric telescopic rod. During use, the electric telescopic rod drives the roller to move upward, and then the roller surface contacts the winding drum. The roller then drives the pressure plate to press down the spring. When the spring is compressed to the appropriate position, the telescopic rod stops moving up and down. In this way, the spring always has an upward thrust on the pressure plate, which avoids the self-adhesive label from becoming loose and messy during winding due to insufficient tension. In addition, the auxiliary device improves the smoothness of the pressure plate's up and down movement. This device has a simple structure, reasonable design, and high practicality.

[0004] However, this device has some shortcomings. First, it uses mechanical springs for pressure application, which increases dramatically with the winding diameter. This is because the pressure increases with the spring compression, leading to excessive pressure in the later stages of winding. This can easily crush the label edges or cause permanent deformation of the material, severely affecting the quality of the finished product, and the pressure cannot be controlled. Second, its operation is single-station winding. After completing one roll, the machine must be stopped to unload and install new cores, causing interruptions in the production process, low equipment utilization, and severely restricting overall production efficiency. Third, manual cutting is usually required at the end of winding. This is not only inefficient and difficult to guarantee the quality of the cut, but also cannot achieve true continuous production due to the lag of manual operation. It also increases labor costs and management difficulty. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a thermal self-adhesive label winding and rewinding device.

[0006] The following technical solution is adopted: a thermal self-adhesive label winding device includes a base plate, a swing arm assembly is fixedly provided at the rear top of the base plate, an adjustment assembly is fixedly provided on one side of the top of the base plate, the adjustment assembly is located below the swing arm assembly, and a cutting assembly is fixedly provided on the side of the top of the base plate away from the swing arm assembly.

[0007] Optionally, the adjustment component includes a hydraulic cylinder, with a support plate fixedly connected to the top of the hydraulic cylinder, and an adaptive pneumatic cylinder fixedly mounted on the top of the support plate.

[0008] Optionally, the swing arm assembly includes a support column, a rotary cylinder is rotatably mounted on the top of the support column, a swing arm body is fixedly connected to the top of the rotary cylinder, and two drive devices are symmetrically rotatably connected to both ends of the swing arm body, with a winding drum fixedly sleeved on the drive end of each drive device.

[0009] Optionally, four telescopic rods are symmetrically fixed at the top of the support plate, and a pressure plate is fixedly connected to the top of the four telescopic rods. Two support rollers are symmetrically fixed at the top of the pressure plate.

[0010] Optionally, a pressure regulating valve and a control module are fixedly provided on the outer wall of the adaptive pneumatic cylinder, and an air outlet and an air inlet are respectively opened at the upper and lower ends of one side of the adaptive pneumatic cylinder.

[0011] Optionally, the cutting assembly includes a drive motor, a sliding groove is fixedly connected to one side of the drive motor, a guide block is slidably connected to the inner wall of the sliding groove, the drive end of the drive motor passes through one side of the sliding groove and is rotatably connected to the through part, a lead screw is fixedly connected to the drive end of the drive motor, the end of the lead screw away from the drive motor passes through the inner wall of the guide block and is threadedly connected to the through part, and the end of the lead screw away from the drive motor is rotatably connected to the inner wall of the sliding groove.

[0012] Optionally, a housing is fixedly connected to the top of the guide block, a drive cylinder is fixedly provided on one side of the housing, a drive block is fixedly provided at the telescopic end of the drive cylinder, the drive block is slidably connected to the inner wall of the housing, two cutters are symmetrically slidably provided on both sides of the drive block, and a cover plate is fixedly connected to one side of the housing by a number of screws.

[0013] Optionally, a first input roll and a second input roll are fixedly provided on both sides of the cutting assembly.

[0014] The technical effects that can be achieved by the technical means of this utility model are as follows:

[0015] (1) In this utility model, by setting an adaptive air cylinder, a constant and gentle pressure is provided. When used with a pressure regulating valve, it can automatically retract downward as the roll diameter increases. At the same time, the support roller can also transmit pressure. The pressure is enough to straighten the loose self-adhesive labels and prevent the self-adhesive labels from being loose and messy during the winding process due to insufficient tension. The pressure in the adaptive air cylinder can be precisely preset and adjusted by the pressure regulating valve. No matter how the winding diameter changes, the pressure can be controlled by adjusting the air volume of the air inlet and outlet, so that the pressure applied by the pressure plate to the surface of the roll material remains constant, thus realizing the controllability of pressure.

[0016] (2) In this utility model, by setting up a swing arm assembly, the swing arm body is rotated by a rotary cylinder, so that the label can be quickly switched from a nearly full roll to an empty roll without stopping the machine, which greatly improves the efficiency of continuous operation of the equipment.

[0017] (3) In this utility model, by setting a cutting component, the label is immediately cut by driving two cutters with a drive cylinder when the roll is about to be fully rolled. The cut is neat and clean, which not only avoids the uncertainty and lag of manual operation, but also effectively eliminates material waste or equipment jamming caused by uneven cutting, ensuring the efficiency, smoothness and intelligence of the final stage of the winding process.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] A preferred embodiment of the thermal self-adhesive label winding device provided by this utility model is, for example... Figures 1 to 5 As shown: A thermal self-adhesive label winding device includes a base plate 1, a swing arm assembly 2 fixedly provided at the rear top of the base plate 1, an adjustment assembly 3 fixedly provided on one side of the top of the base plate 1, the adjustment assembly 3 being located below the swing arm assembly 2, and a cutting assembly 6 fixedly provided on the side of the top of the base plate 1 away from the swing arm assembly 2.

[0028] In this embodiment, the adjustment component 3 includes a hydraulic cylinder 301, a support plate 302 is fixedly connected to the top of the hydraulic cylinder 301, and an adaptive pneumatic cylinder 305 is fixedly provided at the top of the support plate 302.

[0029] The above scheme uses a hydraulic cylinder 301 to lift and lower the top component, so that the support roller 304 contacts the lower surface of the self-adhesive label at the lower winding point of the swing arm assembly 2. By setting an adaptive pneumatic cylinder 305, a constant and gentle pressure is provided. When used with a pressure regulating valve 306, it can automatically retract downward as the roll diameter increases, preventing the label from being crushed.

[0030] In this embodiment, the swing arm assembly 2 includes a support column 201, a rotary cylinder 202 is rotatably provided at the top of the support column 201, a swing arm body 204 is fixedly connected to the top of the rotary cylinder 202, and two drive devices 205 are symmetrically rotatably connected at both ends of the swing arm body 204, and a winding drum 203 is fixedly sleeved on the drive end of the drive device 205.

[0031] The above scheme utilizes the rotary cylinder 202 to provide power, driving the swing arm assembly 2 to rotate precisely around the support column 201 to switch the positions of the two take-up drums 203, while the drive device 205 provides rotational power to the take-up drums 203 to control the take-up speed and tension.

[0032] In this embodiment, four telescopic rods 303 are symmetrically fixed at the top of the support plate 302, and a pressure plate 310 is fixedly connected to the top of the four telescopic rods 303. Two support rollers 304 are symmetrically fixed at the top of the pressure plate 310.

[0033] In the above scheme, the telescopic rod 303 and the adaptive pneumatic cylinder 305 work together to ensure smooth lifting. The pressure plate 310 supports the upper support roller 304 and transmits the support force. The support roller 304 directly contacts and supports the surface of the label roll and is the core roller for transmitting pressure. When used in conjunction with the adaptive pneumatic cylinder 305, the pressure is sufficient to straighten the loose self-adhesive labels and prevent the self-adhesive labels from becoming loose and messy during the winding process due to insufficient tension.

[0034] In this embodiment, a pressure regulating valve 306 and a control module 307 are fixedly provided on the outer wall of the adaptive pneumatic cylinder 305, and an air outlet 309 and an air inlet 308 are respectively opened on the upper and lower ends of one side of the adaptive pneumatic cylinder 305.

[0035] In the above scheme, the pressure regulating valve 306 is connected to the adaptive pneumatic cylinder 305 to precisely set and adjust its internal pressure to adapt to labels of different materials and widths. The control module 307 integrates a new algorithm to coordinate the rotation speed of the hydraulic cylinder 301 and the drive device 205 driving the winding drum 203. The air inlet 308 and the air outlet 309 are respectively connected to an external air source to provide compressed air to the adaptive pneumatic cylinder 305 and to discharge gas when the adaptive pneumatic cylinder 305 contracts.

[0036] In this embodiment, the cutting assembly 6 includes a drive motor 601. A sliding groove 602 is fixedly connected to one side of the drive motor 601. A guide block 605 is slidably connected to the inner wall of the sliding groove 602. The drive end of the drive motor 601 passes through one side of the sliding groove 602 and is rotatably connected to the through part. A lead screw 603 is fixedly connected to the drive end of the drive motor 601. The end of the lead screw 603 away from the drive motor 601 passes through the inner wall of the guide block 605 and is threadedly connected to the through part. The end of the lead screw 603 away from the drive motor 601 is rotatably connected to the inner wall of the sliding groove 602.

[0037] The above scheme uses a drive motor 601 to drive the lead screw 603 to rotate. Since the lead screw 603 is threadedly connected to the guide block 605 through part, the guide block 605 is slidably connected along the inner wall of the sliding groove 602, thereby driving the cutter 606 to move in the front-back direction. When it is necessary to pass the self-adhesive label between the first input roll 4 and the second input roll 5, the cutter 606 is moved backward to avoid the label from contacting the blade of the cutter 606. When cutting is required, the drive motor 601 drives the upper and lower cutters 606 to cover the self-adhesive label for cutting.

[0038] In this embodiment, a housing 607 is fixedly connected to the top of the guide block 605, a drive cylinder 609 is fixedly provided on one side of the housing 607, a drive block 608 is fixedly provided at the telescopic end of the drive cylinder 609, the drive block 608 is slidably connected to the inner wall of the housing 607, two cutters 606 are symmetrically slidably provided on both sides of the drive block 608, and a cover plate 604 is fixedly connected to one side of the housing 607 by a number of screws.

[0039] The above scheme utilizes a drive cylinder 609 to drive a drive block 608 to slide along the inner wall of the housing 607. Due to its shape, the two cutters 606 move closer or further apart in the vertical direction, thereby achieving the purpose of cutting. The cover plate 604 serves a protective function.

[0040] In this embodiment, a first input roll 4 and a second input roll 5 are fixedly provided on both sides of the cutting component 6.

[0041] In the above scheme, the first input roll 4 and the second input roll 5 together carry and supply the main thermal self-adhesive label material roll from the previous process, which facilitates the subsequent winding work.

[0042] Working principle: When operating and using this utility model, as follows... Figures 1 to 5As shown, in use, the drive motor 601 first drives the lead screw 603 to rotate, causing the guide block 605 to slide backward along the inner wall of the sliding groove 602. Then, the self-adhesive label is passed between the first input drum 4 and the second input drum 5, and part of the self-adhesive label is wound onto the outer wall of the take-up drum 203, providing winding force. The hydraulic cylinder 301 drives the top component to rise and fall, so that the support roller 304 contacts the lower surface of the self-adhesive label at the lower take-up point of the swing arm assembly 2. The adaptive pneumatic cylinder 305 provides constant and gentle pressure. The telescopic rod 303 and the adaptive pneumatic cylinder 305 work together to ensure smooth lifting and lowering. The pressure plate 310 supports the upper support roller 304 and transmits the support force. The core roller, which directly contacts and supports the label roll surface, transmits pressure. It works in conjunction with the adaptive pneumatic cylinder 305 to straighten loose self-adhesive labels using pressure, preventing them from becoming loose during winding due to insufficient tension. The pressure regulating valve 306 is connected to the adaptive pneumatic cylinder 305 to precisely set and adjust its internal pressure to accommodate labels of different materials and widths. The control module 307 integrates a new algorithm to coordinate the rotation speed of the hydraulic cylinder 301 and the drive device 205 driving the winding drum 203. The air inlet 308 and air outlet 309 are connected to external air sources to provide compressed air to the adaptive pneumatic cylinder 305 and to discharge gas when the adaptive pneumatic cylinder 305 contracts.

[0043] Once one of the take-up drums 203 has finished winding, the rotary cylinder 202 provides power to drive the swing arm assembly 2 to rotate precisely around the support column 201 to switch the positions of the two take-up drums 203. The drive device 205 provides rotational power to the take-up drum 203 and controls the winding speed and tension.

[0044] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
