Description

Technical Field

[0001] This utility model relates to the field of wool shearing technology, and in particular to a wool shearing based on gear and rack transmission. Background Technology

[0002] Shearings include hand shears and electric shears. Hand shears are structurally similar to regular household scissors, but larger in size. Electric shears are similar to human hairdressing scissors, with a motor driving the blades to swing left and right to cut the wool.

[0003] The structural principle of a conventional electric wool shear is as follows: an eccentric body is mounted on the motor shaft, and a swing arm is mounted on the eccentric body. This converts the rotational motion of the motor into left and right swinging motion. The swing arm pushes the moving blade to swing left and right through the pressure claw. Below the moving blade is a fixed blade, which is fixed to the main body of the machine and does not move.

[0004] Existing electric wool shears based on eccentric bodies require the motor to drive the swing arm via the eccentric body, which in turn drives the pressure claw and moving blade. This has disadvantages such as low efficiency, large vibration, and high noise, resulting in a poor user experience. Utility Model Content

[0005] The purpose of this invention is to provide a wool shear based on gear and rack transmission to solve the problems of low efficiency, high vibration and high noise in the operation of existing eccentric electric wool shears.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a wool shearing device based on gear and rack transmission, comprising:

[0007] The handle contains a motor.

[0008] The transmission module includes a base, a drive gear set, and a driven gear set. The base is fixedly mounted on the handle. The motor shaft of the motor passes through the side wall of the base and connects to the drive component. The drive gear set includes a main drive shaft, a drive gear, and a first incomplete gear. The axis of the main drive shaft is perpendicular to the axis of the motor shaft. The main drive shaft is rotatably mounted on the base.

This results in high transmission efficiency and effectively reduces vibration and noise during the shearing process, thus improving the user experience. Attached Figure Description

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0051] Example 1

[0052] Please see Figure 1-2 6. This utility model provides a technical solution: a wool shearing based on gear and rack transmission, comprising:

[0053] Handle 1, which contains a motor 11;

[0054] The transmission module includes a base 2, a drive gear set 3, and a driven gear set 4. The base 2 is fixedly mounted on the handle 1. The motor shaft of the motor 11 passes through the side wall of the base 2 and is connected to the drive member 12. The drive gear set 3 includes a main drive shaft, a drive gear 31, and a first incomplete gear 32. The axis of the main drive shaft is perpendicular to the axis of the motor shaft. The main drive shaft is rotatably mounted on the base 2. The drive gear 31 and the first incomplete gear 32 are arranged sequentially from top to bottom on the main drive shaft. The drive member 12 is used to drive the drive gear 31 to rotate. The driven gear set 4 includes a driven shaft, a driven gear 41, and a second incomplete gear 42. The driven shaft is rotatably mounted on the base 2. The driven gear 41 and the second incomplete gear 42 are arranged sequentially from top to bottom on the driven shaft. The drive gear 31 meshes with the driven gear 41.

[0055] The blade module includes a fixed blade 5 and a movable blade 6. The fixed blade 5 is fixedly mounted on the base 2, and the movable blade 6 is slidably connected to the fixed blade 5. The back of the movable blade 6 is provided with a rack 61 that meshes with the first incomplete gear 32 and the second incomplete gear 42.

[0056] The tooth positions of the first incomplete gear 32 and the second incomplete gear 42 are both not more than 180 degrees apart, and the phase difference between the first incomplete gear 32 and the second incomplete gear 42 is not less than 180 degrees.

[0057] At least one bearing is provided at the end of the main drive shaft and the driven shaft to enable rotatable mounting with the base 2 and the fixed blade 5.

[0058] The driving component 12 is a bevel gear, and both the driving gear 31 and the driven gear 41 are bevel gears. The driving component 12 meshes with the driving gear 31 to realize the power transmission between the driving component 12, the driving gear 31, and the driven gear 41.

[0059] The blade module also includes a pressure member 7 and a pressure bar 71. The pressure member 7 is placed on the moving blade 6, and the pressure bar 71 is placed on the pressure member 7. The threaded rod of the connecting bolt 72 passes through the pressure bar 71 and is threaded onto the fixed blade 5. A spring is fitted on the threaded rod of the connecting bolt 72, with one end of the spring contacting the pressure bar 71 and the other end contacting the bolt head of the connecting bolt 72. The pressure member 7 and the pressure bar 71 are used to achieve elastic compression of the moving blade 6.

[0060] By rotating the connecting bolt 72, the distance between the bolt head and the moving blade 6 can be adjusted, thereby compressing the spring and adjusting the pressure applied by the pressure bar 71 to the pressure member 7, thus adjusting the pressure on the moving blade 6.

[0061] The pressure component 7 can also be integrally molded with the moving blade 6 to simplify the structure. Similarly, the moving blade 6 can be integrally molded with the rack 61.

[0062] See Figure 6 The base 2 is equipped with a housing 8, which effectively hides and protects the transmission mechanism.

[0063] A fan 13 is provided on the handle 1, and an air duct is provided on the housing of the motor 11. The fan 13 is used to dissipate heat from the motor 11, effectively controlling the temperature of the wool shears during long-term use, so as to protect the motor.

[0064] Working Principle: When the wool shears are in operation, the motor inside the handle 1 transmits power to the drive gear set 3 via the drive component 12 at the end of the motor shaft. The drive gear set 3 drives the driven gear 41 of the driven gear set 4 to rotate, causing the first incomplete gear 32 and the second incomplete gear 42 to independently drive the rack 61 to move. The first incomplete gear 32 and the second incomplete gear 42 do not mesh with the rack 61 simultaneously, causing the rack 61 and the moving blade 6 to reciprocate, thus achieving shearing. During the shearing process, the rotation of the motor shaft at the output end of the motor inside the handle 1 is converted into the horizontal reciprocating motion of the moving blade 6 through the drive gear set 3 and the driven gear set 4. This results in high transmission efficiency and effectively reduces vibration and noise during the shearing process, improving the user experience.

[0065] Example 2

[0066] Please see Figure 3 Based on the above embodiments, this embodiment further improves upon the following technical solutions: the drive gear 31 and the first incomplete gear 32 on the drive gear set 3 can be designed as a single unit. The half-tooth gear and the full-tooth gear are made as a single unit, and the half-tooth gear meshes with the rack for transmission.

[0067] The driven gear set 4 can adopt the above design to simplify the gear set structure.

[0068] Example 3

[0069] Please see Figure 4 Based on the above embodiments, this embodiment further improves upon the following technical solution: the driving component 12 is a bevel gear, and a driving gear 33 is also provided on the main drive shaft. The driving gear 33 is a bevel gear and meshes with the driving component 12.

[0070] The drive unit 12 achieves the rotation of the main drive shaft through the additional bevel gear 33 on the main drive shaft, which in turn causes the drive gear 31 to drive the driven gear 41 to rotate.

[0071] Example 4

[0072] Please see Figure 5Based on the above embodiments, this embodiment further improves upon the following technical solution: the driving component 12 is a worm gear, and a worm wheel 34 is also provided on the main drive shaft, which meshes with the driving component 12.

[0074] Example 5

[0075] Please see Figure 7 Based on the above embodiments, this embodiment further improves upon the following technical solution: the pressure member 7 is provided with a groove 73 for storing grease.

[0076] The grease stored in the groove 73 can reduce wear between the pressure component 7 and the pressure bar 71, and improve the reliability of the equipment.

[0077] Example 6

[0078] Please see Figure 8 Based on the above embodiments, this embodiment further improves upon the following technical solution: the tip of the fixed blade 5 is provided with an upwardly curved vertical portion 51.
