Description

Technical Field

[0001] The utility model belongs to the technical field of printing paper feeding, in particular to a paper feeding device for label printing equipment. Background Art

[0002] The application of labels and the continuous development of label varieties have naturally promoted the development of label printing technology. Label printing covers all printing methods such as flat, convex, concave, and mesh.

[0003] In the label printing process, paper feeding equipment is indispensable. However, most existing paper feeding equipment lacks inertia stop components, which causes the paper to stop midway or continue to feed due to inertia when the speed is unstable, resulting in paper wrinkles. This not only easily causes paper jams in the equipment, but also greatly affects product production efficiency and product quality. Utility Model Content

[0004] The purpose of the utility model is to provide a paper feeding device for label printing equipment. By setting a resistance lock, specifically rotating the resistance lock, the resistance lock is threadedly moved on the outer surface of the shaft, and then the resistance pad on the back of the resistance lock contacts the turntable, ensuring that the turntable can rotate but with slight resistance, thereby solving the problem that most of the existing paper feeding devices of label printing equipment lack an inertial stop component, which makes the paper easily wrinkled and affects production efficiency and product quality.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model discloses a paper feeding device for label printing equipment, comprising a base and an operating table, wherein the front side of the base is rotatably connected to a turntable, the interior of the turntable is rotatably connected to a shaft rod, a resistance lock is provided on the front side of the turntable, the back side of the resistance lock is fixedly connected to a resistance pad, the back side of the resistance pad contacts the front side of the turntable, the interior of the resistance lock is threadedly connected to the outer surface of the shaft rod, and the resistance lock generates friction through the contact between the resistance pad and the turntable, which can effectively avoid paper wrinkles caused by the inertia of the paper when the paper feeding process stops halfway or the speed is unstable, thereby improving production efficiency and product quality.

[0007] Furthermore, the front and back of the top of the operating table are fixedly connected to a support frame 1, and the corresponding sides of the two support frames are each provided with a limit frame. The bottom of the limit frame is fixedly connected to the top of the operating table, and the limit frame contacts both sides of the paper, so that the paper can only move horizontally on the operating table, which can effectively prevent the paper from being offset during transportation and causing the paper to wrinkle, thereby improving the stability of the device.

[0008] Furthermore, the top of the support frame 1 is fixedly connected to the side of the turntable with a support frame 2, the top of the support frame 2 is fixedly connected to two spring rods, the bottom of the spring rods is fixedly connected to a pressing plate, the pressing plate is pressed on the paper by the elastic force of the spring inside the spring rod, and the front section of the pressing plate is arc-shaped, which can not only effectively prevent the paper from warping and forming wrinkles, but also intercept foreign objects on the surface of the paper, thereby further improving the stability of the device.

[0009] Furthermore, a support frame three is fixedly connected to the top center of the support frame one, and an air outlet is fixedly connected to the bottom of the support frame three. The support frame three supports the air outlet so that the air outlet is located directly above the paper. In this way, the hot air can be fully blown onto the paper, greatly improving the working efficiency of the hot air blower.

[0010] Furthermore, a hose is fixedly connected to the top of the support frame, and a hot air blower is fixedly connected to the air inlet at the bottom of the hose. The hot air blower can blow hot air through the hose and the air outlet to dry the water in the paper, thereby avoiding unclear printing and paper jams in the printing equipment due to excessive humidity in the paper, thereby greatly improving the practicality of the device.

[0011] Furthermore, the front and back sides of the right side of the operating table are fixedly connected to support frames four, and the upper and lower sides corresponding to the two support frames four are rotatably connected to shaft rods two, and the surfaces of the two shaft rods two are fixedly connected to paper feed wheels. The paper is clamped between the two paper feed wheels, and the paper is fed out by the mutual rotation of the two paper feed wheels, which makes the paper transportation more stable and further improves the stability of the device.

[0012] Furthermore, the backs of the two shaft rods are fixedly connected to gears, the back of the gear located above is fixedly connected to a motor, the output end of the motor is fixedly connected to the back of the gear through a coupling, and one motor drives the two shaft rods to move simultaneously through the gears, which not only avoids wrinkles caused by inconsistent rotation of the shaft rods during paper transportation, but also is beneficial to energy saving and environmental protection, and increases work efficiency.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a resistance lock, specifically rotates the resistance lock, so that the resistance lock moves in a thread on the outer surface of the shaft, and then the resistance pad on the back of the resistance lock contacts the turntable, ensuring that the turntable can rotate but with slight resistance, which can effectively avoid the influence of inertia on the turntable, thereby improving production efficiency and product quality.

[0015] 2. The utility model sets a pressure piece. Specifically, during the paper feeding process, the spring rod on the support frame 2 will press the pressure piece at the bottom of the spring rod onto the paper under the elastic force of the spring. By applying appropriate pressure, the paper can be kept flat during the transmission process to prevent the paper from warping.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
