Description

Technical Field

[0001] This utility model relates to the field of small material conveying technology, and in particular to a drive component for grinding and cleaning small materials. Background Technology

[0002] During industrial production or assembly, some parts need to be ground and cleaned before they can be used. For example, in some electronic devices, small parts such as glass or metal sheets need to be ground and cleaned to ensure precision.

[0003] Currently, in the market, when cleaning small parts, the small parts are generally transported to the grinding and cleaning mechanism inside the box via a conveyor shaft for targeted processing.

[0004] However, in existing grinding and cleaning equipment, the drive components are installed inside the housing when the drive conveyor shaft rotates, which is inconvenient for subsequent maintenance and repair. In addition, the grinding and cleaning liquids are also prone to splashing onto the surface, causing corrosion to the drive components and affecting their service life. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems in the prior art where the drive components are installed inside the housing, which is inconvenient for subsequent maintenance and repair, and the grinding and cleaning liquids are also prone to splashing onto the surface, causing corrosion to the drive components and affecting their service life. Therefore, this invention proposes a drive component for grinding and cleaning small parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drive assembly for grinding and cleaning small parts includes a rotating shaft rotatably connected to the outer wall of a housing; an active magnetic wheel is fixedly connected to the rotating shaft; and a conveying shaft extends out of the housing near one end of the rotating shaft and is fixedly connected to a passive magnetic wheel.

[0008] Preferably, the passive magnetic wheel is located above the active magnetic wheel.

[0009] Preferably, the distance between the passive magnetic wheel and the active magnetic wheel is 2-10 mm.

[0010] Preferably, the active magnetic wheel is designed in multiple sets.

[0011] Preferably, the side wall of the housing near the passive magnetic wheel is provided with a slot; a sealing ring is fitted on the conveying shaft and the sealing ring is fixed in the slot.

[0012] Preferably, a support plate is fixedly connected inside the slot, and the conveying shaft is rotatably connected inside the support plate; the support plate is located on the side of the sealing ring near the passive magnetic wheel.

[0013] Preferably, a protective plate is fixedly connected to the side wall of the box, and the passive magnetic wheel and the active magnetic wheel are located inside the protective plate.

[0014] Preferably, a pulley is fixedly connected to one end of the rotating shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The drive assembly for grinding and cleaning small parts is designed with the rotating shaft, active magnetic wheel, and passive magnetic wheel on the outside of the housing. This allows for maintenance and repair without entering the housing, enabling workers to perform maintenance directly from the outside. This is quick and convenient. At the same time, designing the drive assembly on the outside of the housing also prevents liquid from splashing onto the surface of the drive assembly during grinding and cleaning, avoiding corrosion and ensuring the service life.

[0017] 2. The drive assembly for grinding and cleaning small parts uses a sealing ring design to prevent liquid from splashing out through the connection between the conveyor shaft and the housing during the grinding and cleaning process, thus avoiding corrosion and improving stability and service life.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Example:

[0029] like Figures 1-7 A drive assembly for grinding and cleaning small parts includes a rotating shaft 3, which is rotatably connected to the outer wall of a housing 1. The rotating shaft 3 is horizontal and an active magnetic wheel 301 is fixedly connected to the rotating shaft 3. A conveying shaft 2 extends out of the housing 1 near one end of the rotating shaft 3 and is fixedly connected to a passive magnetic wheel 201. The conveying shaft 2 is designed in multiple groups, which are horizontal and parallel to each other, and are used to convey small parts to be processed. The number is generally 5-20. Each conveying shaft 2 has a passive magnetic wheel 201 fixedly connected to one end of its extension out of the housing 1.

[0030] The conveyor shaft 2 rotates within the housing 1 via bearings.

[0031] The active magnetic wheel 301 is designed in multiple sets, and the number of active magnetic wheels 301 is the same as the number of passive magnetic wheels 201.

[0032] The active magnetic wheel 301 and the passive magnetic wheel 201 have the same magnetic poles, either N or S.

[0033] When small parts to be processed need to be transported, they are placed on the conveyor shaft 2 through the inlet 101 on the housing 1. Then, the rotating shaft 3 is driven to rotate, which drives the active magnetic wheel 301 to rotate. The active magnetic wheel 301 then drives the passive magnetic wheel 201 to rotate through magnetic force, which in turn drives the conveyor shaft 2 to rotate, moving the small parts and transporting them to the grinding and cleaning mechanism for grinding and cleaning.

[0034] The rotating shaft 3 can be driven by a motor, which is fixed to the side wall of the housing 1, and the output end of the motor is fixedly connected to the rotating shaft 3.

[0035] By designing the drive components, such as the rotating shaft 3, the active magnetic wheel 301, and the passive magnetic wheel 201, on the outside of the housing 1, maintenance and repair can be carried out without entering the housing 1. This is quick and convenient. At the same time, designing the drive components on the outside of the housing 1 also prevents liquid from splashing onto the surface of the drive components during grinding and cleaning, thus avoiding corrosion and ensuring the service life.

[0036] Meanwhile, through the magnetic transmission of the active magnetic wheel 301 and the passive magnetic wheel 201, there is no direct contact between the active magnetic wheel 301 and the passive magnetic wheel 201. The distance between the passive magnetic wheel 201 and the active magnetic wheel 301 is 2-10 mm, which also avoids the generation of friction loss during transmission. Furthermore, since it is a magnetic transmission, when the weight of the small parts on the conveyor shaft 2 is large, when it exceeds the rated load, it can automatically slip, and the conveyor shaft 2 will be in a stationary state. At this time, the motor will still be in a rotating state, which will not damage the drive components and the motor.

[0037] The passive magnetic wheel 201 is located above the active magnetic wheel 301, and there is a corresponding active magnetic wheel 301 below each passive magnetic wheel 201.

[0038] like Figures 6-7 The side wall of the housing 1 near the passive magnetic wheel 201 is provided with a slot 4; a sealing ring 402 is fitted on the conveying shaft 2, the conveying shaft 2 and the sealing ring 402 are rotatably connected and mutually sealed, and the sealing ring 402 is fixed in the slot 4.

[0039] The sealing ring 402 is designed to block liquid from splashing out through the connection between the conveyor shaft 2 and the housing 1 during the grinding and cleaning process, thus preventing corrosion and improving stability and service life.

[0040] like Figures 6-7A support plate 401 is fixedly connected inside the slot 4, and the conveying shaft 2 is rotatably connected inside the support plate 401. The conveying shaft 2 is in contact with the inner wall of the support plate 401. The support plate 401 is located on the side of the sealing ring 402 near the passive magnetic wheel 201.

[0041] The support plate 401 provides support for the conveyor shaft 2, preventing all the weight from being applied to the sealing ring 402 and ensuring the sealing performance of the sealing ring 402.

[0042] like Figures 1-3 A protective plate 6 is fixedly connected to the side wall of the box 1, and the passive magnetic wheel 201 and the active magnetic wheel 301 are located inside the protective plate 6.

[0043] The protective plate 6 serves a protective function, preventing staff from accidentally touching components such as the active magnetic wheel 301 and the passive magnetic wheel 201.

[0044] like Figure 1 , Figures 4-7 One end of the rotating shaft 3 is fixedly connected to a pulley 5.

[0045] Depending on the site conditions, if the motor cannot be fixedly installed on the side wall of the housing 1, the motor can be fixedly connected to other places, and then the rotating shaft 3 can be rotated by a belt.

[0046] A pulley 5 is also fixed at the output end of the motor, and the belt is sleeved between the two pulleys 5 for transmission.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
