Description

Technical Field

[0001] The utility model relates to the field of rewinding machines, in particular to a self-adhesive label rewinding machine. Background Art

[0002] The main function of the rewinding machine is to rewind the rolled self-adhesive labels to meet different packaging, transportation or storage requirements. The rewinding machine can count the labels while rewinding to ensure the accuracy of the quantity.

[0003] After retrieval, the publication number CN210973257U discloses a rewinding machine for self-adhesive label production, which includes a mounting base, a feeding module, a winding module, and a counting module. The feeding module and the winding module both include a motor, a material disk, and a roller concentrically arranged with the material disk. The material disk is horizontally arranged. The bottom end of the roller passes through the material disk and is rotatably installed on the mounting base and connected to the motor. The motor is fixedly installed in the mounting base. The counting module includes a tensioning component and a counting component. The tensioning component includes a mounting plate and a tensioning unit arranged on the mounting plate. The tensioning unit includes two rotating shafts vertically arranged on the mounting plate and a tensioning shaft vertically arranged between the two rotating shafts. The bottom ends of the rotating shaft and the tensioning shaft are both rotatably installed on the mounting plate through bearings, and the tensioning shaft can elastically move along the midline direction between the two rotating shafts. The counting component includes a Hall sensor, a single-chip microcomputer, and a display. The Hall sensor is arranged on the support rod on the mounting plate and is connected to the single-chip microcomputer through a signal line.

[0004] Existing self-adhesive label rewinding machines often have the problem of being unable to adapt to different inner diameter sizes of the material cylinders. Since the inner diameter of the self-adhesive label material cylinders may vary due to different suppliers, batches or uses, the rewinding machine must have good inner diameter adjustment ability. However, existing rewinding machines often can only adapt to material cylinders with a fixed inner diameter, resulting in frequent adjustment of the equipment or even replacement of the entire rewinding machine when changing material cylinders with different inner diameters. This not only increases the production cost but also reduces the production efficiency. Moreover, during the feeding and winding processes, the self-adhesive labels are prone to deviation.

This flexibility also enhances the market competitiveness of the rewinder, enabling it to meet a wider range of market demands.

[0031] 2. During the unwinding and rewinding processes, the connection mechanism not only firmly fixes the label cartridge but also effectively reduces the offset of the self-adhesive labels through the design of the deviation rectifying disc.

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0044] Refer to Figures 1-4 , an adhesive label rewinder, comprising: a rewinder main body 1; two connecting mechanisms 2, installed on the rewinder main body 1 and used for connecting label cartridges 3 of different sizes; two label cartridges 3, respectively connected to the two connecting mechanisms 2; the connecting mechanism 2 includes a connecting rod 205 and a plurality of limiting seats 208. Among them, the connecting rod 205 is connected to the rewinder main body 1, the label cartridge 3 is connected to the connecting rod 205, and the plurality of limiting seats 208 are connected around the connecting rod 205 and are arranged in a circumferential array to fix the position of the label cartridge 3 on the connecting rod 205. The plurality of limiting seats 208 are set to move simultaneously closer to or away from the axis of the connecting rod 205 to fix label cartridges 3 with different inner diameters; the connecting rod 205 includes: a cavity 206 formed on the connecting rod 205; a plurality of through holes 207 opened on the inner wall of the cavity 206 and arranged in a circumferential array, and the limiting seats 208 are connected in the through holes 207. Through the connecting mechanism 2, it is possible to easily adapt to and stably connect label cartridges 3 with different inner diameters. This flexibility not only improves the versatility of the equipment but also reduces the complex adjustments required for changing the cartridge size, thereby improving production efficiency and operation convenience.

[0045] Refer to Figure 3 and Figure 4, the connecting mechanism 2 further includes: a pressing seat 209, connected inside the cavity 206, and configured to simultaneously press a plurality of limiting seats 208 when only moving downward inside the cavity 206, so that the limiting seats 208 extend out of the through hole 207 and contact the inner wall of the label cartridge 3; a lead screw 210, one end of which is connected to the pressing seat 209, and the other end passes through the cavity 206 and extends to the outside of the connecting rod 205; a knob 211, arranged at the top end of the connecting rod 205, and the lead screw 210 is connected to the knob 211; a chassis 202, mounted on the connecting rod 205 for placing the label cartridge 3; a deviation rectifying disk 203, connected to the connecting rod 205 for rectifying the label on the label cartridge 3. The deviation rectifying disk 203 is configured to move closer to or away from the chassis 202 to adapt to label cartridges 3 of different heights. By controlling the lead screw 210 to drive the pressing seat 209 through the knob 211, precise adjustment of the limiting seats 208 is achieved, eliminating the need to manually adjust each limiting seat 208 one by one, saving time and improving the adjustment accuracy. The design of the deviation rectifying disk 203 can be adaptively adjusted according to the height of the label cartridge 3, effectively correcting the offset of the label during the rewinding process and improving the accuracy of rewinding.

[0046] Refer to Figure 3 and Figure 4 , the deviation rectifying disk 203 includes: an adjusting seat 204, mounted on the deviation rectifying disk 203 and threadedly connected to the connecting rod 205, and configured to drive the deviation rectifying disk 203 to move when rotating on the connecting rod 205. The adjusting seat 204 and the connecting rod 205 are connected by a threaded connection, which facilitates flexible adjustment of the position of the deviation rectifying disk 203 on the connecting rod 205, enabling the distance between the deviation rectifying disk 203 and the chassis 202 to be flexibly adjusted to adapt to label cartridges 3 of different sizes.

[0047] Refer to Figure 3 , a rotating seat 201, connected to the rewinder main body 1, and one end of the connecting rod 205 is connected to the rotating seat 201. The rotating seat 201 is used to provide rotational power for the connecting rod 205.

[0048] Refer to Figure 1 , two rotating shafts 4, connected to the rewinder main body 1; a counting unit 5, connected to the rewinder main body 1, arranged between the two rotating shafts 4, and used to count the self-adhesive labels during the rewinding process.

[0049] During use, place the label cartridge 3 on the chassis 202 and adjust its position to ensure that the center of the cartridge is aligned with the connecting rod 205. Rotate the knob 211 so that the lead screw 210 drives the extrusion seat 209 to move downward in the cavity 206. The extrusion seat 209 simultaneously squeezes several limit seats 208, causing them to extend out of the through hole 207 and closely fit the inner wall of the label cartridge 3, firmly fixing the label cartridge 3. Connect the deviation correction disk 203 to the connecting rod 205. By rotating the adjusting seat 204 on the deviation correction disk 203, move the deviation correction disk 203 closer to or farther away from the chassis 202 until the deviation correction disk 203 maintains appropriate contact with the label on the label cartridge 3 to effectively correct the deviation of the label during the rewinding process. Start the rewinder main body 1, and the rotating seat 201 begins to provide rotational power for the connecting rod 205, driving the connecting rod 205 and the label cartridge 3 thereon to rotate. The self-adhesive label on the label cartridge 3 is gradually rewound into another label cartridge 3 as the cartridge rotates. During the rewinding process, the counting unit 5 is located between the two rotating shafts 4 and counts the self-adhesive labels in the rewinding process in real time to ensure the accuracy of the production quantity.

[0050] In summary, compared with the prior art, the following beneficial effects are achieved:

[0051] The flexible adaptation of different inner diameter label cartridges 3 is realized through the connection mechanism 2, enabling the rewinder to easily handle different label cartridges 3 without frequent equipment adjustment or replacement of the entire rewinder, reducing production costs and complexity. This flexibility also enhances the market competitiveness of the rewinder, enabling it to meet a wider range of market demands.

[0052] During the unwinding and rewinding processes, the connection mechanism 2 not only firmly fixes the label cartridge 3 but also effectively reduces the deviation of the self-adhesive label through the design of the deviation correction disk 203. The deviation correction disk 203 can be adaptively adjusted according to the height of the label cartridge 3 to ensure that the label remains flat and accurate during the rewinding process, improving the rewinding quality.

[0053] Components such as the connection mechanism 2 and the deviation correction disk 203 are all designed modularly, facilitating disassembly, replacement, and maintenance. By controlling the lead screw 210 with the knob 211 to drive the extrusion seat 209, precise adjustment of the limit seats 208 is achieved, eliminating the need to manually adjust each limit seat 208 one by one, saving time and reducing the operation difficulty, making the use of the rewinder more convenient and efficient.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
