Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an anti-sticking paper mounting structure and printing equipment. Background Art

[0002] Linerless paper is gradually being used in printing equipment due to its advantages of lower carbon and more environmentally friendly. In the prior art, the linerless paper roll is generally directly mounted on the paper threading shaft, and paper stoppers are set at both ends of the paper threading shaft to stop and limit the linerless paper roll. Since both ends of the linerless paper roll are glued, after using a few rolls of paper, a lot of glue will stick to the paper stoppers, and some of the glue will even transfer to the paper threading shaft, causing the paper bin and the paper threading shaft to become sticky and tangled, resulting in problems such as inaccurate paper feeding or the motor being unable to pull the paper, affecting the printing quality. The torque required by the motor becomes larger, which will reduce the life of the printing equipment. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model aims to provide an anti-sticking paper loading structure, which can keep the paper baffle board and the paper threading shaft from being glued or entangled, thereby ensuring the printing quality and prolonging the life of the printing equipment.

[0004] To solve the above problems, the technical solution adopted by the utility model is as follows: an anti-sticking paper loading structure, including a paper threading shaft, a paper stopper and an anti-sticking layer, the paper threading shaft is used to thread a bottomless paper roll, the paper stopper is connected to both ends of the paper threading shaft and is used to stop the two ends of the bottomless paper roll, and the anti-sticking layer is connected to the side of the paper stopper close to the bottomless paper roll.

[0005] Compared with the prior art, the beneficial effect of the utility model lies in that an anti-sticking paper loading structure is provided on the side of the paper baffle close to the bottomless paper roll. During the paper feeding process, the glue at both ends of the bottomless paper roll will not adhere to the paper baffle, nor will it be transferred to the paper threading shaft, thereby keeping the paper baffle and the paper threading shaft free of glue and entanglement, ensuring accurate paper feeding and printing quality, and will not increase the paper dragging torque of the motor, thereby increasing the life of the printing equipment.

[0006] The above-mentioned anti-sticking paper loading structure has anti-sticking lines on the anti-sticking layer.

[0007] In the above-mentioned anti-sticking paper loading structure, the anti-sticking lines are raised strips extending along the radial direction of the anti-sticking layer, and a plurality of the raised strips are distributed along the circumference of the anti-sticking layer.

[0008] In the above-mentioned anti-sticking paper mounting structure, the anti-sticking layer is a silica gel layer.

[0009] In the above-mentioned anti-sticking paper loading structure, the anti-sticking layer is coated on the surface of the paper retaining paper.

[0010] The utility model also discloses a printing device, comprising the above-mentioned anti-sticking paper mounting structure. Since the printing device adopts the above-mentioned anti-sticking paper mounting structure, it at least has all the beneficial effects that the above-mentioned anti-sticking paper mounting structure can bring.

[0011] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Description of the accompanying drawings: 100 paper threading shaft, 200 paper baffle, 300 anti-sticking layer, 310 raised strip, 400 bottomless paper roll. DETAILED DESCRIPTION

[0014] The embodiments of the present invention are described in detail below. Figure 1 The embodiment of the utility model provides an anti-sticking paper loading structure, including a paper threading shaft 100, a paper stopper 200 and an anti-sticking layer 300. The paper threading shaft 100 is used to thread a bottomless paper roll 400. The paper stopper 200 is connected to both ends of the paper threading shaft 100 and is used to stop both ends of the bottomless paper roll 400. The anti-sticking layer 300 is connected to a side of the paper stopper 200 close to the bottomless paper roll 400. The anti-sticking paper loading structure is provided with an anti-sticking layer 300 on a side of the paper stopper 200 close to the bottomless paper roll 400. During the paper feeding process, the glue at both ends of the bottomless paper roll 400 will not adhere to the paper stopper 200, and will not be transferred to the paper threading shaft 100, so that the paper stopper 200 and the paper threading shaft 100 can be kept free of glue and entanglement, thereby ensuring the accuracy of paper feeding, thereby ensuring the printing quality, and will not increase the paper dragging torque of the motor, thereby improving the life of the printing device.

[0015] Further, the anti-adhesive layer 300 is provided with anti-adhesive lines, and the contact area between the glue on both ends of the bottomless paper roll 400 and the anti-adhesive layer 300 is smaller, so the glue is not easy to transfer and adhere to the anti-adhesive layer 300. In some embodiments, the anti-adhesive layer 300 is circular, and the anti-adhesive lines are raised strips 310 extending radially along the anti-adhesive layer 300, and the raised strips 310 are distributed along the circumference of the anti-adhesive layer 300. Further, the anti-adhesive layer 300 is a silicone layer, and the anti-adhesive layer 300 made of silicone material has a better anti-adhesive effect. In some embodiments, a small amount of silicone oil can also be applied to the anti-adhesive layer 300, which can further improve the anti-adhesive effect without affecting the quality of the bottomless paper. Further, the anti-adhesive layer 300 is coated on the surface of the paper baffle 200, and a glue protection step can be added when the paper baffle 200 is injection molded, so that the anti-adhesive layer 300 is coated on the surface of the paper baffle 200.

[0016] The embodiment of the utility model further provides a printing device, comprising the above-mentioned anti-sticking paper mounting structure. Since the printing device adopts the above-mentioned anti-sticking paper mounting structure, it at least has all the beneficial effects that can be brought by the above-mentioned anti-sticking paper mounting structure.
