Description

Technical Field

[0001] The present invention relates to the field of accessories for office equipment, and particularly to a paper feeding device for a self-adhesive printer. Background Art

[0002] At present, laser printers on the market can only print 100 - 200 sheets. For label paper with the size of A4 paper, especially at the edges where there is glue, when the temperature is relatively high, the glue overflows and adheres to the paper feeding channel, making the paper unable to be printed. Since the edges of self-adhesive paper will have glue overflow and remain on the paper feeding channel, blocking the channel and causing paper jams. Therefore, it is necessary to improve such a structure to overcome the above defects. Summary of the Invention

[0003] The purpose of the present invention is to provide a paper feeding device for a self-adhesive printer.

[0004] The above technical purpose of the present invention is achieved by the following technical solutions: A paper feeding device for a self-adhesive printer includes a housing. A fixing frame is arranged inside the housing. A paper picking mechanism is rotatably arranged at the upper end of the fixing frame. A paper separating mechanism is rotatably connected below the paper picking mechanism. A paper feeding mechanism is also rotatably arranged below the fixing frame.

[0005] By adopting the above technical solutions, the self-adhesive paper enters after the paper picking wheel rotates. Then the paper separating mechanism separates the self-adhesive paper. The waste residue after separation is collected by the collection handle. The separated self-adhesive paper is sent out from the paper feeding channel by the paper feeding mechanism.

[0006] The paper picking mechanism includes a rotatably arranged paper picking wheel. Both ends of the paper picking wheel are fixed to the upper end of the fixing frame. The paper picking wheel is of a cylindrical structure. A paper picking layer is arranged on the paper picking wheel. A paper picking gear is arranged on one side of the paper picking wheel.

[0007] By adopting the above technical solutions, the paper picking mechanism can pick up the self-adhesive paper. The arrangement of the paper picking layer can increase the friction force to ensure the picking up of the paper.

[0008] The paper separating mechanism includes a paper separating wheel. The paper separating wheel is located at the lower end of the fixing frame. A paper separating layer is arranged on the paper separating wheel. A paper separating gear is arranged on one side of the paper separating wheel.

[0009] By adopting the above technical solutions, the paper separating layer on the paper separating wheel increases the friction to ensure the success rate of paper separation.

[0010] The paper feeding mechanism includes a paper feeding roller. Paper feeding driven wheels are arranged at both ends of the paper feeding roller. The distance between the two paper feeding driven wheels is greater than the lengths of the paper picking wheel and the paper separating wheel 31.

[0011] By adopting the above technical solution, the paper feeding driven wheels arranged on both sides reduce the contact area with the self-adhesive paper and reduce the contact with the glue during the working process.

[0012] The further setting of the present invention is that: the fixing frame further includes two symmetrically arranged fixing plates, and a collecting handle for collecting waste paper is rotatably arranged inside the fixing plates.

[0013] By adopting the above technical solution, the setting of the collecting handle ensures that the waste residue can be centrally collected and processed, and will not cause damage to the inside of the printer.

[0014] The further setting of the present invention is that: three transmission gears are arranged on one side of the fixing frame.

[0015] The further setting of the present invention is that: the transmission gear, the paper picking gear and the paper separating gear are all on the same side, and the paper picking gear is connected to the paper separating gear through the transmission gear.

[0016] By adopting the above technical solution, two transmission gears are used, so that the paper feeding mechanism has two levels of followers, greatly improving the paper separating power and ensuring that the self-adhesive can be separated.

[0017] The further setting of the present invention is that: a spring is also arranged between the paper feeding roller and the housing, and the paper feeding roller is rotatably fixed on the housing.

[0018] By adopting the above technical solution, the spring arranged on the paper feeding roller can apply a pre-tightening force to the paper feeding roller, increasing the pressure between the paper feeding roller and the driven wheel, increasing the paper feeding force, and ensuring that the paper can be smoothly sent out.

[0019] The further setting of the present invention is that: the paper picking layer is made of EPDM rubber, and a number of parallel lines are arranged on the surface of the paper picking layer.

[0020] By adopting the above technical solution, the paper picking layer made of EPDM rubber and the lines arranged on the surface increase the friction force and increase the paper picking force.

[0021] The further setting of the present invention is that: the paper separating layer is made of rubber.

[0022] By adopting the above technical solution, setting a paper separating layer made of rubber on the paper separating wheel can improve the paper separating efficiency and avoid the phenomenon of slipping during paper separation.

[0023] The further setting of the present invention is that: a paper feeding channel is arranged between the housing and the fixing frame, and a non-stick coating is arranged on the paper feeding channel.

[0024] By adopting the above technical solution, the non-stick coating provided on the paper feeding channel can prevent the glue on the adhesive label from adhering to the channel, causing the channel to be blocked, or adhering to the printed paper.

[0025] In summary, the present invention has the following beneficial effects: the paper feeding driven wheels arranged on both sides reduce the contact area with the self-adhesive paper and reduce the contact with glue during the working process; the setting of the collection handle ensures that the waste residue can be collected and processed in a centralized manner without causing damage to the inside of the printer; the two transmission gears are adopted, so that the paper picking mechanism has two-level following, which greatly improves the paper separation power and ensures that the self-adhesive can be separated; the paper picking layer made of rubber material is arranged on the paper picking wheel, which can improve the paper picking efficiency and avoid slipping during paper picking; the two transmission gears are adopted, so that the paper picking mechanism has two-level following, which greatly improves the paper separation power and ensures that the self-adhesive can be separated; the EPDM rubber material paper picking layer and the texture arranged on the surface increase the friction and increase the paper picking force; the non-stick coating arranged on the paper feeding channel can prevent the glue on the self-adhesive from adhering to the channel, causing the channel to be blocked, or adhering to the printed paper.
