[0002] The rotary label die-cutter is a kind of mechanical equipment widely used in packaging, printing, pharmaceutical, food and other industries. It is mainly used for die-cutting (full cutting, half cutting), creasing, hot stamping, laminating and automatic waste discharge of non-metallic materials, self-adhesive, EVA, double-sided tape, electronics, mobile phone pads, etc. The equipment uses steel knives, hardware molds, steel wires (or templates carved from steel plates) to apply pressure through the stamping plate to roll the printed products or cardboard into the required shape. The equipment can cut labels by rotating the rotary wheel, but long-term use of the equipment will cause aging or electrical structure failure, resulting in loose cutting structure. The loose cutting structure is easy to contact with the transmission structure, resulting in greater wear of the transmission structure and a low service life. There are certain shortcomings.

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] The following describes some embodiments of the utility model in conjunction with the accompanying drawings to provide a rotary label die-cutting machine.

[0023] Embodiment 1:

[0024] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a rotary label die-cutting machine, including a supporting assembly 100, a die-cutting assembly 200, a driving assembly 300, a rotary assembly 400 and a limiting assembly 500.

[0025] Specifically, the support assembly 100 includes a support plate 101 and an adjustment hole 1011 opened on the support plate 101. The adjustment hole 1011 allows the drive assembly 300 and the wheel assembly 400 to move on the support plate 101 to adjust the height. A scale line 1012 is set at the front end of the support plate 101. The inner bearing of the support plate 101 is connected to a roller 102, which facilitates the conveying of labels.

[0026] Specifically, the die-cutting assembly 200 is arranged on the top of the support plate 101. The die-cutting assembly 200 includes a top plate 201 arranged on the top of the support plate 101, a hydraulic cylinder 202 arranged on the top plate 201, a die-cutting plate 203 arranged at the bottom of the hydraulic cylinder 202, and a buzzer 204 arranged on the top of the top plate 201. The hydraulic cylinder 202 can be extended and retracted to drive the die-cutting plate 203 to move downward, and can be die-cut into a desired shape by pressing.

[0027] Specifically, the driving assembly 300 includes a rotating shaft 301 inserted into the adjusting hole 1011, a first fixed seat 302 connected to the rotating shaft 301 with a bearing, a second fixed seat 304 connected to the rotating shaft 301 with a bearing, a driving motor 303 arranged on the rear side of the rotating shaft 301 and an electric push rod 305 arranged at the bottom of the first fixed seat 302 and the second fixed seat 304. The electric push rod 305 can be controlled to be extended and retracted. The retractable electric push rod 305 can drive the rotating wheel assembly 400 to move up and down so as to adjust the height of the rotating wheel assembly 400. It is suitable for labels of different thicknesses and has a wide range of use. A reference rod 3041 is arranged on the outer side of the second fixed seat 304. When adjusting the height of the rotating wheel assembly 400, the reference rod 3041 can be aligned with the scale line 1012 for precise adjustment.

[0028] Specifically, the wheel assembly 400 includes a wheel body 401 inserted on the rotating shaft 301 and a blade 402 arranged outside the wheel body 401. The rotating blade 402 can cut the label for use. A rubber ring 403 is bonded to the outer side of the wheel body 401, and the rubber ring 403 can rub against the label to convey the label. A tightening knob 404 is threadedly connected on the wheel body 401, and the tightening knob 404 can be loosened. After the tightening knob 404 is loosened, the position of the wheel assembly 400 can be adjusted for cutting.

[0029] Specifically, the limit assembly 500 includes a fixed plate 501 arranged on the outside of the support plate 101, a rotating rod 502 connected to the bearing of the fixed plate 501, a limit seat 503 threadedly connected to the rotating rod 502, and a pressure sensor 504 arranged on the limit seat 503. A round hole is opened on the limit seat 503, and the rotating rod 502 can rotate. The rotating rotating rod 502 can drive the limit seat 503 to move up and down until the limit seat 503 contacts the first fixed seat 302 or the second fixed seat 304. After the contact, the limit seat 503 plays a limiting effect to prevent the drive assembly 300 and the wheel assembly 400 from loosening and causing the blade 402 to scratch the roller 102. At the same time, the pressure sensor 504 can detect the pressure of the first fixed seat 302 or the second fixed seat 304 on the limit seat 503. When the pressure is large, the external control device will remind the user through the buzzer 204 so as to repair the electric push rod 305 in time.

[0030] The working principle and use process of the utility model are as follows: when in use, the electric push rod 305 can be controlled to be extended and retracted, and the extended electric push rod 305 can drive the rotating wheel assembly 400 to move up and down. When moving, the reference rod 3041 can be aligned with the scale line 1012 and moved to a suitable height. Then, the rotating rod 502 of the limiting assembly 500 is rotated, and the rotating rotating rod 502 can drive the limiting seat 503 to move up and down until the limiting seat 503 contacts the first fixed seat 302 or the second fixed seat 304. After the contact, the limiting seat 503 plays a limiting effect. To prevent the drive assembly 300 and the wheel assembly 400 from loosening and causing the blade 402 to scratch the roller 102, the pressure sensor 504 can detect the pressure of the first fixed seat 302 or the second fixed seat 304 on the limit seat 503. When the pressure is high, the external control device will remind the user through the buzzer 204 so that the electric push rod 305 can be repaired in time, and then the tightening knob 404 can be loosened. After the tightening knob 404 is loosened, the position of the wheel assembly 400 can be adjusted for cutting. At the same time, the rubber ring 403 can rub against the label for transportation.
