Description

Technical Field

[0001] This utility model relates to the field of material transportation, and in particular to a clean roller conveyor structure with the characteristic of reducing dust generation. Background Technology

[0002] Current material handling lines typically use conveyor belts and conveyor rollers for transporting materials. However, belts are prone to wear and tear during operation, causing dust to fall out, while roller structures lack stable operation and cannot meet the transportation needs of some small components with high dust prevention requirements.

[0003] In view of this, this technical solution proposes a clean roller conveyor structure with dust reduction characteristics. It adopts a beltless structure to reduce the falling and scattering of fine dust, and is equipped with a closed transmission cavity to isolate internal dust. Small-sized components are rolled and transported through the exposed needle roller structure. The overall structure is simple, easy to assemble, and adjustable in length and width. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide a clean roller conveyor structure with dust-reducing characteristics, thereby addressing the problem of the lack of dust-preventing and stable operation of small component transport structures in the prior art.

[0005] To achieve the above objectives, this utility model provides a clean roller conveyor structure with dust reduction characteristics, comprising a conveyor line body consisting of an outer shell, a transmission mechanism, and friction roller needles. The transmission mechanism includes a horizontally placed friction shaft and a series of protruding rings arranged on the surface of the friction shaft. The main body of the friction shaft is concealed inside the outer housing, with a drive connector exposed at one end of the outer housing for connection with an external drive device. The friction wheel needle roller includes a friction head and a contact head extending from one side of the friction head. The middle section of the contact head is sleeved by a bearing. The other end of the friction head contacts the protruding ring. A through hole is provided on one side of the outer housing for the contact head to pass through. The bearing is engaged with the inside of the through hole.

[0006] As a further embodiment of this utility model, the outer shell is characterized in that it has a hexagonal rectangular structure, including a front frame and a back frame located on the front and rear sides of the transmission mechanism, and a top plate and a bottom plate located on the upper and lower sides of the transmission mechanism. Each of the through holes is opened in the front frame, and the two ends of the transmission mechanism are limited by side baffles.

[0007] As a further embodiment of this utility model, the contact head is characterized by having a spring sleeved on the outside of one end near the friction head, a limiting ring being provided between the friction head and the bearing, and the two ends of the spring contacting the bottom of the friction head and one end of the limiting ring, respectively.

[0008] As a further embodiment of this utility model, the friction shaft is a metal rotating shaft structure, and the friction head is a silicone head structure.

[0009] As a further improvement of this utility model, the contact head is characterized by being a soft rubber column structure.

[0010] As a further improvement of this utility model, the bearing is characterized in that there are two bearings, which are located on both sides of the limiting ring.

[0011] The beneficial effects of this utility model are as follows: This technical solution encloses the transmission mechanism and the main components of the friction wheel needle rollers within an outer housing. A raised ring on the surface of the friction shaft drives the friction head of the friction wheel needle rollers to rotate, thereby enabling material transfer through a contact head that passes through a through-hole. This encloses the main friction and transmission processes within the housing, effectively isolating dust generated by component wear and significantly improving the cleanliness of the transportation environment. Simultaneously, it eliminates the need for traditional belt drives, avoiding the problem of belt wear and debris shedding. The direct and compact transmission method between the raised ring and the friction head ensures the stability and reliability of transporting small components. The overall structure is simple, easy to assemble and maintain, and effectively solves the problem of stable transport of small components in environments with high dust protection requirements.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0021] Please see the appendix Figure 1-5 , The main body (1) of the transport line in this technical solution consists of an outer shell (10), a transmission mechanism (11), and friction wheel needle rollers (12). The transmission mechanism (11) includes a horizontally placed friction shaft (110). The surface of the friction shaft (110) is provided with sequentially arranged protruding rings (1100). The main body of the friction shaft (110) is hidden inside the outer shell (10), with only one end exposed for connecting an external drive head (111) to an external drive device. The friction wheel needle rollers... The needle (12) includes a friction head (120) and a contact head (121) extending from one side of the friction head (120). The middle section of the contact head (121) is sleeved by a bearing (123). The other end of the friction head (120) is in close contact with the protruding ring (1100) on the friction shaft (110). A through hole (104) is opened on one side of the outer housing (10) for the contact head (121) to pass through. The bearing (123) is locked inside the through hole (104).

[0022] For example, when the external drive unit drives the friction shaft (110) to rotate through the drive connector (111), the raised ring (1100) pushes the friction head (120) to rotate, thereby driving the contact head (121) of the friction wheel needle roller (12) to rotate, realizing the rolling transmission of materials. Since most of the components of the transmission mechanism (11) and the friction wheel needle roller (12) are enclosed in the outer housing (10), the dust leakage caused by friction during operation is effectively reduced. At the same time, the smoothness and reliability of the transportation process are ensured by the support of the bearing (123) and the precise transmission of the raised ring (1100). It is particularly suitable for the transportation of small components with high dust protection requirements, avoiding the dust problem caused by the wear of traditional belts. The overall structure is compact and easy to assemble.

[0023] It is understandable that in this scheme, the main body (1) of the transport line can be a single structure, or two main bodies can be arranged opposite each other and cooperate to form a whole, and the spacing can be adjusted. Carrier plates, carrier belts, etc. can be set in this structure. When the main body (1) of the transport line is a single structure, the small components are completely contacted by the contact head (121) and the displacement is completed by rotation. When it is assembled from two main bodies (1), the components are located between the contact heads (121) on both sides, and a carrier belt or carrier plate is laid between the contact heads (121).

[0024] Reference Appendix Figure 2 , 3As a preferred embodiment of the present invention, in this solution, the outer shell (10) is a hexagonal rectangular body, which is specifically formed by the front frame (100) and back frame (101) located on the front and rear sides of the transmission mechanism (11), as well as the top plate (105) and bottom plate (103) located on the upper and lower sides, which together enclose the transmission mechanism (11). The two ends of the transmission mechanism (11) are limited by the side baffles (102), and each through hole (104) is opened on the front frame (100) for the contact head (121) of the friction wheel needle (12) to pass through.

[0025] Understandably, the structure that completely encloses the transmission mechanism (11) inside the rectangular housing can prevent dust and debris generated during operation from leaking out to the outside to the greatest extent, providing a relatively closed and clean working environment.

[0026] Of course, the methods of achieving a closed shell are not limited to this. For example, the outer shell (10) can also be designed as a cylindrical cover, or its various plates can be fixed by non-removable methods such as welding. However, this preferred solution adopts a detachable plate structure (e.g., connected by screws) to facilitate disassembly for replacement, cleaning and maintenance of internal components, thereby improving the practicality and maintainability of the structure.

[0027] Reference Appendix Figure 5 As a preferred embodiment of the present invention, in this technical solution, a spring (122) is sleeved on the outside of the contact head (121) near the friction head (120), and a limiting ring (124) is provided between the friction head (120) and the bearing (123). The two ends of the spring (122) are in contact with the bottom of the friction head (120) and one end of the limiting ring (124), respectively.

[0028] Specifically, the spring force of the spring (122) continuously pushes the friction head (120) against the protruding ring (1100) on the friction shaft (110), ensuring that there is always a stable contact between them and avoiding slippage or free rotation. At the same time, the addition of the spring (122) also gives the friction wheel needle roller (12) a certain buffering capacity. When the contact head (121) contacts the transported component, non-rigid flexible contact can be achieved, reducing the impact on the component.

[0029] Reference Appendix Figure 3 , 4 As a preferred embodiment of this utility model, the friction shaft (110) in this solution adopts a metal shaft structure, while the friction head (120) in contact with it adopts a silicone head structure. The large coefficient of friction between silicone and the metal surface can prevent slippage. Moreover, the silicone material is relatively soft, and it generates less noise and wear debris during the friction process, which helps to achieve the low dust characteristic.

[0030] Reference Appendix Figure 3-5 In a preferred embodiment of this utility model, the contact head (121) of the friction wheel needle roller (12) is a soft rubber column structure, which has the characteristics of being soft and having high friction. It can generate sufficient friction with the surface of the component or the carrier plate, carrier disk or carrier belt, thereby effectively driving them to move smoothly and preventing slippage or deviation during transmission. At the same time, the soft rubber material is soft and will not scratch the surface of the object.

[0031] Alternatively, the material of the contact head (121) is not limited to this; it can also be made of rigid plastic with anti-slip textures added to its surface, or other elastic composite materials can be used.

[0032] Reference Appendix Figure 5 As a preferred embodiment of this utility model, in this technical solution, there are two bearings (123), which are respectively fixed on both sides of the limiting ring (124) to prevent them from shaking or swaying when rotating at high speed, thus ensuring stability and reliability of the entire transportation process.

[0033] The following points need to be explained: (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0034] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure can be combined with each other.

[0035] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
