Abstract
Description
Technical Field
[0001] This utility model belongs to the field of die-cutting machine technology, specifically a die-cutting machine for copperplate self-adhesive labels. Background Technology
[0002] The production process of coated self-adhesive labels requires die-cutting using a die-cutting machine to form the labels into a specific shape for later use. During the die-cutting process, the waste material generated after die-cutting separates from the substrate. At this point, the waste material and the formed coated label paper may exert a certain pulling force, causing the edges of the formed coated label paper to separate from the substrate. This is especially problematic in low winter temperatures, when the workshop temperature has not yet reached the constant operating temperature, and the low temperature can even lead to label detachment (separation of the label paper surface from the substrate), resulting in poor stability. Therefore, this application proposes a die-cutting machine for coated self-adhesive labels. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Depend on Figures 1 to 5 The present invention discloses a die-cutting machine for copperplate self-adhesive labels, comprising a die-cutting frame 1, a feeding roller 2 provided at one end of the die-cutting frame 1, and a combined die-cutting roller 3, a finished product collecting roller 4, a waste product collecting roller 5, and a flat pressure roller group 6 arranged sequentially at the other end of the die-cutting frame 1. The flat pressure roller group 6 is located between the combined die-cutting roller 3 and the finished product collecting roller 4. A preheater 7 is provided at the top of the die-cutting frame 1, located between the feeding roller 2 and the combined die-cutting roller 3.
[0023] The combined die-cutting roller 3 performs die-cutting operations on the copperplate self-adhesive labels. The finished product collection roller 4 and the waste product collection roller 5 collect the finished products and waste products after die-cutting, respectively. During the waste discharge process, the waste material may separate from the substrate, which may cause the edge of the finished product material to detach from the substrate. At this time, the flat pressure roller group 6 presses the finished product material together, so that the finished product material and the substrate are fully bonded, avoiding the label falling off.
[0024] The preheater 7 consists of a shell 8 and a slow-flow heating assembly 9. A temperature controller is installed at the top of the shell 8. The slow-flow heating assembly 9 is fixedly connected to the inside of the shell 8. The slow-flow heating assembly 9 consists of a first flow guide shroud 10, a first electric heating plate 11, a second flow guide shroud 12, and a second electric heating plate 13. The first flow guide shroud 10, the first electric heating plate 11, the second flow guide shroud 12, and the second electric heating plate 13 are all fixedly connected to the inside of the shell 8. The first electric heating plate 11 is located in the middle position inside the first flow guide shroud 10. An annular flow channel 14 is formed between the first electric heating plate 11 and the first flow guide shroud 10. The second electric heating plate 13 is located in the middle position inside the second flow guide shroud 12. An annular flow channel 25 is formed between the second electric heating plate 13 and the second flow guide shroud 12. Several flow guide fans 16 are fixedly installed inside the annular flow channel 14. Several flow guide fans 17 are fixedly installed inside the annular flow channel 25.
[0025] The first electric heating plate 11 and the second electric heating plate 13 are heated. The first guide fan 16 and the second guide fan 17 are started, which enables hot air to flow inside the first annular flow channel 14 and the second annular flow channel 15 to achieve internal circulation. The flow of hot air can improve heating efficiency, and the internal circulation can reduce heat loss. The first electric heating plate 11 and the second electric heating plate 13 can also achieve radiant heating, further improving heating efficiency and avoiding the situation of label dropping due to excessively low temperature in winter.
[0026] Two temperature sensors 18 are fixedly installed at the top of the first deflector 10 and the bottom of the second deflector 12, which can realize temperature monitoring.
[0027] The first flat slot 19 and the second flat slot 20 are formed at the two ends between the first air guide 10 and the second air guide 12, respectively, which allows the label to pass through. The flat structure can reduce heat loss.
[0028] The front of the housing 8 is provided with a door 21, and the inner side wall of the housing 8 is fixedly provided with a heat insulation layer 22, which can improve the heat insulation effect and further reduce heat loss.
[0029] A label inlet 23 matching the first flat slot 19 is provided at the middle position of one end of the housing 8, and a label outlet 24 matching the second flat slot 20 is provided at the middle position of the other end of the housing 8, so that the label can enter and exit the housing 8.
[0030] During operation, the system is equipped with a feeding roller, a combined die-cutting cutter, a finished product collection roller, a waste product collection roller, and a flat pressure roller assembly. This allows for the die-cutting of coated self-adhesive labels. The flat pressure roller assembly presses the formed label surface after waste removal, preventing the surface material from separating from the substrate. A slow-flow heating assembly consisting of a first flow guide hood, a first electric heating plate, a second flow guide hood, and a second electric heating plate, along with two flow guide fans, preheats the coated self-adhesive labels before die-cutting, preventing label detachment in low winter temperatures and improving die-cutting stability.
