Description

Technical Field

[0001] The utility model relates to the technical field of rubber wheels, and more specifically to an improved paper pickup wheel. Background Art

[0002] The current copiers, printers, scanners and bank ATMs all involve rubber wheels. The main function of this wheel is to transport the paper in the paper box of the copier and printer or the banknotes in the ATM one by one. The key point is to ensure that there will not be multiple sheets of paper being transported out at one time, and there must not be a situation where paper jams prevent the paper from being transported. When the wheels on the machine reach a certain lifespan, the wheel surface will slip, resulting in the failure to transport paper or banknotes or multiple sheets being transported out. As a result, the machine cannot operate normally.

[0003] To avoid the situation of multiple feeding and paper jam, the paper feed rollers in copiers, printers, scanners and cash machines must be replaced regularly. The replacement frequency and life of the paper feed rollers are different for each model, ranging from a few thousand to 300,000 sheets. The market price of the rollers ranges from 10 yuan to 100 yuan, but the labor cost of each replacement is at least several hundred yuan. Therefore, reducing the number of wheel replacements will greatly reduce the cost of using the machine.

[0004] Most of the current paper feed wheels use the friction of the rubber surface. The friction is generated by grinding the rubber surface to make it rough and produce certain texture. After a period of use, the texture is worn out and the rubber surface becomes very smooth, losing the function of driving paper. The wheel needs to be replaced in time.

[0005] Based on the above problems, we provide an improved pickup wheel.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content

[0007] In order to solve the problems raised in the above background technology, the utility model provides an improved paper pickup wheel.

[0008] The improved paper pickup wheel provided by the utility model adopts the following technical solutions:

[0009] The improved paper pickup wheel comprises a rotating wheel; a mesh granular pattern arranged on the outer surface of the rotating wheel for increasing the friction of the rotating wheel; and a mounting hole penetrating through the side end of the rotating wheel for mounting the rotating wheel.

[0010] Preferably, annular ribs are provided at both ends of the rotating wheel.

[0011] Preferably, the reticular particle pattern is composed of convex-shaped pads.

[0012] Preferably, the reticular particle pattern is composed of concave-shaped grooves.

[0013] Preferably, the runner is molded by rubber material.

[0014] In summary, the present utility model includes the following beneficial technical effects:

[0015] By changing the rough surface ground on the rubber surface in the prior art to directly form a reticular particle pattern, the contact surface and friction force on the surface of the runner are increased. All the reticular particle patterns have inclined surfaces, which is beneficial to the smooth passage of paper. There are continuous raised ribs (annular ribs) on both sides of the runner, which facilitate the smooth passage of paper and play a guiding role, effectively preventing paper jams. The service life of the runner can be improved through the reticular particle pattern. The generation of paper jams is prevented through the inclined surfaces of the runner and the continuous ribs (annular ribs) on both sides. The friction force of the runner is increased through the rough texture on the surface of the reticular particle pattern, ultimately improving the service life of the runner and reducing the replacement cycle of the runner.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will be readily apparent by reference to the drawings and the following detailed description.

[0022] Embodiment 1

[0023] An embodiment of the utility model discloses an improved paper feed roller. Refer to Figure 1 , the improved paper feed roller includes a rotating wheel 1; a mesh particle pattern is formed on the outer side surface of the rotating wheel 1 for increasing the friction of the rotating wheel 1; a mounting hole 2 is formed through the side end of the rotating wheel 1 for mounting the rotating wheel 1.

[0024] Specifically, annular ribs 3 are arranged at both ends of the rotating wheel 1.

[0025] Specifically, the mesh particle pattern is composed of a convex-shaped pad 4.

[0026] Specifically, the rotating wheel 1 is formed by rubber, silica gel or polyurethane by die pressing.

[0027] Specifically, the hardness of the rotating wheel 1 is 25A - 60A.

[0028] By changing the rough surface ground on the rubber surface in the prior art and directly forming a mesh particle pattern, the contact surface and friction of the surface of the rotating wheel 1 are increased. All the mesh particle patterns have inclined surfaces, which is beneficial to the smooth passing of the paper. There are continuous raised ribs (annular ribs 3) on both sides of the rotating wheel 1, which is convenient for the paper to pass smoothly and plays a guiding role, effectively preventing paper jams.

[0029] At the same time, there is a flat surface on the mesh particle pattern surface of the rotating wheel 1, and a rough pattern is designed on this flat surface, which increases the surface friction of the rotating wheel 1.

[0030] The service life of the rotating wheel 1 can be improved through the mesh particle pattern. The generation of paper jams can be prevented through the inclined surface of the rotating wheel 1 and the continuous ribs (annular ribs 3) on both sides. The friction of the rotating wheel 1 is increased through the rough pattern on the surface of the mesh particle pattern. Finally, the service life of the rotating wheel 1 is improved and the cycle of replacing the rotating wheel 1 is reduced.

There are continuous raised ribs (annular ribs 3) on both sides of the runner 1, facilitating the smooth passage of paper and playing a guiding role, effectively preventing paper jams.

[0038] Meanwhile, there is a flat surface on the reticular particle pattern surface of the runner 1, and rough patterns are designed on this flat surface, which increases the surface friction force of the runner 1.

[0039] The service life of the runner 1 can be improved through the reticular particle pattern. The inclined surface of the runner 1 and the continuous ribs (annular ribs 3) on both sides prevent paper jams. The rough patterns on the surface of the reticular particle pattern increase the friction force of the runner 1, ultimately improving the service life of the runner 1 and reducing the cycle of replacing the runner 1.
