Description

Technical Field

[0001] The utility model relates to the technical field of printer drive shafts, and more specifically, to a printer drive shaft with a positioning function. Background Art

[0002] Printer equipment is a variety of equipment that uses modern information technology to improve office efficiency and quality. It usually has the characteristics of automation, intelligence, and networking. Among them, printer equipment can automatically complete multiple functions such as printing, copying, scanning, and faxing. The transmission shaft is one of its important components, which is responsible for transmitting the power of the motor to the print head or paper conveying system.

[0003] The installation of the printer drive shaft is difficult, resulting in insufficient installation accuracy, affecting the operation of the equipment, causing vibration and reducing the operating stability, and is also not conducive to maintenance and repair. On the other hand, the printer drive shaft is generally set inside the printer. When the printer works for a long time, the internal heat is high, and the contact area between the drive shaft and the air is insufficient, resulting in poor heat dissipation capacity, reduced balance of the drive shaft, and increased vibration and noise. Therefore, a printer drive shaft with positioning function is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a printer drive shaft with a positioning function that can increase the contact area with the air, improve the heat dissipation capacity, reduce the vibration and noise transmission of the transmission rod, and improve the overall stability.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A printer drive shaft with a positioning function comprises a motor connecting part, one end of which is provided with a fixing part, and the fixing part is provided with a driven connecting part away from the motor connecting part; the fixing part comprises a driving connecting rod connected to one end of the motor connecting part, the driving connecting rod is provided with a cylindrical structure, one end of the driving connecting rod away from the motor connecting part is provided with a motor rod, one end of the motor rod away from the driving connecting rod is provided with a driven connecting rod, and one end of the driven connecting rod away from the motor rod is provided with a driven rod.

[0007] The utility model is further configured as follows: the motor connecting part includes a shaft head guide, a connecting head is provided at one end of the shaft head guide close to the fixing part, the connecting head is configured as a column adapted to the shape of the shaft head guide, a shaft head fixing groove is provided on one side of the connecting head, and the shaft head fixing groove is configured as a plane tangent to the driving connecting rod.

[0008] By adopting the above technical solution, the shaft head guide is used to facilitate the connection of the shaft head of the motor or other driving equipment, and the shaft head fixing groove provided on the connecting head is used to facilitate the positioning and direction confirmation of the motor or other driving equipment.

[0009] The utility model is further configured as follows: the motor rod is configured as a cylindrical structure, and its diameter is larger than the diameter of the driving connecting rod; and a fixing groove is provided at one end of the motor rod close to the driving connecting rod.

[0010] The utility model is further configured as follows: a bolt hole is penetrated through one end of the motor rod near the motor connection part, the bolt hole is configured as a cylindrical through hole structure, and the axial direction of the bolt hole is perpendicular to the axial direction of the motor rod.

[0011] The utility model is further configured as follows: a driven connecting rod is arranged at one end of the motor rod close to the driven connecting part, and the driven connecting rod is arranged as a cylindrical structure, and its diameter is smaller than the diameter of the motor rod.

[0012] By adopting the above technical solution, the driving connecting rod provides good heat dissipation and reduces the overall weight. At the same time, when the transmission shaft rotates at high speed, the transmission of vibration and noise can be reduced, thereby improving the operating performance of the transmission system. The through hole can improve the heat dissipation efficiency, reduce the overall mass, and play a role in shock absorption and noise reduction.

[0013] The utility model is further configured as follows: the driven connecting part includes a driven connecting column, the driven connecting column is arranged at one end of the driven rod away from the motor rod, the diameter of the driven connecting column is smaller than the diameter of the driven rod, a driven guide rod is arranged at one end of the driven connecting column away from the driven rod, the driven guide rod is configured as a cylindrical structure, and its diameter is consistent with that of the driven rod, and the driven guide rod is provided with a driven guide away from the driven connecting column.

[0014] By adopting the above technical solution, the driven connecting column is fixed on the internal parts of the office equipment that match its shape. When the transmission shaft is running, the driven connecting column is rotationally connected to the parts, and the driven guide is conveniently aligned with the parts inside the office equipment. The driven guide rod is close to the plane of the driven connecting column to limit the movement of the parts and prevent the transmission shaft from falling off.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. The shaft head guide facilitates the connection of the shaft head of the motor or other driving equipment, and the shaft head fixing groove opened on the connecting head facilitates the positioning and direction confirmation of the motor or other driving equipment.

[0017] 2. By opening the fixing groove on the motor rod, the direction of the motor or other driving equipment can be further confirmed, or other transmission mechanisms such as gears, rollers, etc. can be installed. The driving connecting rod provides good heat dissipation. At the same time, when the transmission shaft rotates at high speed, it can reduce the transmission of vibration and noise, thereby improving the operating performance of the transmission system. The through hole inserts the positioning pin or bolt to ensure the position of the transmission shaft in the equipment. The driven connecting rod connects the motor rod and the driven rod, which can transmit the driving force to the end, improve heat dissipation, and play a role in shock absorption and noise reduction.

[0018] 3. The driven connecting column is fixed on the internal parts of the office equipment that match its shape. When the transmission shaft is running, the driven connecting column is rotationally connected to the parts, and the driven guide is convenient for aligning the internal parts of the office equipment. The plane of the driven guide rod close to the driven connecting column limits the movement of the parts and prevents the transmission shaft from falling off. BRIEF DESCRIPTION OF THE DRAWINGS
