Description

Technical Field

[0001] This utility model relates to the field of logistics conveying system technology, specifically to an adjustable roller transmission module. Background Technology

[0002] In various automated production lines, logistics conveying systems, and material handling equipment, the transmission device, as a core component, plays a crucial role in transporting objects according to a preset path and speed. Currently, the mainstream drive mode of the transmission devices widely used in the industry is a single motor driving an overall transmission mechanism. That is, a single motor outputs power, which, through transmission components such as gears, chains, belts, or drive shafts, drives the transmission components (such as conveyor belts, drive rollers, etc.) along the entire conveying line to operate at a uniform speed, thereby achieving the batch transport of objects.

[0003] However, this traditional single-motor unified drive method has gradually revealed significant technical shortcomings in practical applications, making it difficult to achieve independent spacing adjustment or stopping of individual or multiple objects within a column of conveyed goods. In batch conveying scenarios, when it is necessary to fine-tune the spacing of specific individual or partial objects within a column of conveyed goods, or when it is necessary to stop conveying them individually due to reasons such as inspection failure or process suspension, the traditional single-motor unified drive system cannot independently control the motion state of local transmission components. Once adjustment or stopping occurs, all objects on the entire conveyor line will be affected, greatly limiting the operational flexibility and applicability of the equipment. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide an adjustable-pitch roller drive module, which has the advantage of being able to adjust the spacing between transported objects, thus solving the problem that roller drive modules cannot adjust the spacing between transported objects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-pitch roller transmission module, comprising: A frame, the frame including a horizontal plate, a left support plate is provided on the left side of the horizontal plate, a right support plate is provided on the right side of the horizontal plate, the bottom right side of the left support plate is fixedly connected to the horizontal plate by bolts and nuts, and the bottom left side of the right support plate is fixedly connected to the horizontal plate by bolts and nuts. A multi-roller transmission structure includes a motor, which is located on the right side of a right-side support plate. The output end of the motor passes through the right-side support plate and extends to the left side of the right-side support plate, where a first roller is fixedly connected. The left side of the first roller passes through the left-side support plate and extends to the left side of the left-side support plate, where a first pulley is fixedly connected. A second pulley is located on the front of the first pulley, and a synchronous belt is provided on the surface of the second pulley. The rear end of the synchronous belt is in close contact with the surface of the first pulley, and the surface of the second pulley is in close contact with the front end of the inner wall of the synchronous belt. A second roller is fixedly connected to the right side of the second pulley, and the right side of the second roller passes through the left-side support plate and extends to the right side of the left-side support plate.

[0006] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the left side of both the front and back sides of the motor, and the left side of the connecting plate is fixedly connected to the right side of the right support plate by bolts.

[0007] As a preferred embodiment of this utility model, a through hole one is provided on the right side of the left support plate, and a through hole two is provided on the right side of the right support plate.

[0008] In a preferred embodiment of this invention, fixed bearings are fixedly connected to the left sides of both roller one and roller two, and limit bearings are fixedly connected to the right sides of both roller one and roller two. The surface of the outer ring of the fixed bearing is fixedly connected to the interior of through hole one, and the surface of the outer ring of the limit bearing is fixedly connected to the interior of through hole two.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves stable assembly of the overall module structure by setting up a frame, providing reliable support for subsequent transmission operations; by setting up a multi-roller transmission structure, a dual-roller collaborative transmission mode is formed. Compared with the traditional single-motor driven overall transmission method, the spacing of conveyed objects can be flexibly adjusted by controlling the output speed of a single motor or by cooperating with multiple such modules. At the same time, it provides basic structural support for the independent spacing adjustment of single or multiple objects, effectively improving the operational flexibility and applicability of the transmission module.

[0010] 2. By setting a fixed connecting plate and using bolts to fix the connecting plate to the right support plate, this utility model further enhances the installation stability of the motor on the module.

[0011] 3. By providing through holes one and two, this utility model provides suitable assembly space for the installation of rollers one and two. The opening of through holes one and two not only facilitates the insertion and installation of rollers one and two on the left and right support plates, but also plays a certain role in limiting the radial position of rollers one and two, preventing lateral deviation of rollers one and two during rotation, and ensuring that rollers one and two are always on the preset transmission path, thus providing structural guarantee for the stable conveying of objects and the adjustment of spacing.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 4 As shown, the present invention provides an adjustable pitch roller transmission module, comprising: The frame 1 includes a horizontal plate 101. A left support plate 102 is provided on the left side of the horizontal plate 101, and a right support plate 103 is provided on the right side of the horizontal plate 101. The bottom right side of the left support plate 102 is fixedly connected to the horizontal plate 101 by bolts and nuts, and the bottom left side of the right support plate 103 is fixedly connected to the horizontal plate 101 by bolts and nuts. The multi-roller transmission structure 2 includes a motor 21, which is located on the right side of the right support plate 103. The output end of the motor 21 passes through the right support plate 103 and extends to the left side of the right support plate 103, where a roller 22 is fixedly connected. The left side of the roller 22 passes through the left support plate 102 and extends to the left side of the left support plate 102, where a pulley 23 is fixedly connected. A pulley 24 is located on the front of the pulley 23. A synchronous belt 25 is located on the surface of the pulley 24. The rear end of the synchronous belt 25 is in close contact with the surface of the pulley 23, and the surface of the pulley 24 is in close contact with the front end of the inner wall of the synchronous belt 25. A roller 26 is fixedly connected to the right side of the pulley 24. The right side of the roller 26 passes through the left support plate 102 and extends to the right side of the left support plate 102.

[0016] refer to Figure 1 The motor 21 has a connecting plate 3 fixedly connected to the left side of both the front and back sides. The left side of the connecting plate 3 is fixedly connected to the right side of the right support plate 103 by bolts.

[0017] As a technical optimization of this utility model, by setting a fixed connecting plate 3 and using the bolts to fix the connecting plate 3 to the right support plate 103, the installation stability of the motor 21 on the module is further enhanced.

[0018] refer to Figure 1 and Figure 2 A through hole 4 is provided on the right side of the left support plate 102, and a through hole 5 is provided on the right side of the right support plate 103.

[0019] As a technical optimization of this utility model, by setting through hole 4 and through hole 5, suitable assembly space is provided for the installation of roller 22 and roller 26. The opening of through hole 4 and through hole 5 not only facilitates the insertion and installation of roller 22 and roller 26 on the left support plate 102 and the right support plate 103, but also plays a certain limiting role in the radial position of roller 22 and roller 26, preventing lateral displacement of roller 22 and roller 26 during rotation, and ensuring that roller 22 and roller 26 are always on the preset transmission path, providing structural guarantee for stable conveying of objects and spacing adjustment.

[0020] refer to Figure 3 Fixed bearings 6 are fixedly connected to the left side of roller 1 22 and roller 2 26, and limit bearings 7 are fixedly connected to the right side of roller 1 22 and roller 2 26. The surface of the outer ring of the fixed bearing 6 is fixedly connected to the inside of through hole 1 4, and the surface of the outer ring of the limit bearing 7 is fixedly connected to the inside of through hole 2 5.

[0021] As a technical optimization of this utility model, by setting a fixed bearing 6 and a limiting bearing 7, the frictional resistance between the first roller 22 and the second roller 26 and the left support plate 102 and the right support plate 103 when they rotate is reduced, the wear of the components of the first roller 22, the second roller 26 and the left support plate 102 and the right support plate 103 is reduced, the rotation efficiency of the first roller 22 and the second roller 26 is improved, the energy consumption of the motor 21 is reduced, and the first roller 22 and the second roller 26 are not prone to axial movement when rotating at high speed or bearing the weight of the conveyed object, thus ensuring the smoothness of the transmission process and improving the accuracy of the object spacing adjustment.

[0022] The working principle and usage process of this utility model are as follows: In use, the frame 1 first provides stable support for the entire device. Its horizontal plate 101 is fixedly connected to the left support plate 102 and the right support plate 103 via bolts and nuts, forming a solid installation foundation. All components of the multi-roller transmission structure 2 are precisely assembled based on this frame 1. In the multi-roller transmission structure 2, the motor 21 located on the right side of the right support plate 103 serves as the power source. Its output end passes through the right support plate 103 and is fixedly connected to roller 22. After the motor 21 starts, it directly drives roller 22 to rotate. Simultaneously, the pulley 23 on the left side of roller 22, passing through the left support plate 102 and connected thereto, rotates synchronously with roller 22. Since pulley 23 is in close contact with pulley 24 on the front side via the synchronous belt 25, the rotation of pulley 23 drives pulley 24 to rotate synchronously through the transmission action of the synchronous belt 25. The roller 26 fixedly connected to the right side of pulley 24 will then rotate accordingly. This allows a single motor 21 to drive two rollers, roller 22 and roller 26, in coordinated operation, ensuring stable power transmission. If it is necessary to reduce the distance between objects, the corresponding single motor 21 can be controlled to increase its speed, driving the rollers in that section, such as roller 22 and roller 26, to rotate faster, thus increasing the conveying speed of subsequent objects and reducing the distance between them and the objects in front. If it is necessary to increase the distance between objects, the corresponding motor 21 can be controlled to decrease its speed or stop briefly, causing the rollers in that section to decelerate or pause their rotation, allowing the objects in front to continue to be conveyed while the subsequent objects temporarily slow down or stop, thereby increasing the distance. If it is necessary to stop one or more objects in the entire column, the corresponding motor 21 carrying that object can be precisely controlled to stop its operation, causing the rollers in that section to stop rotating, achieving independent stopping of one or more objects without affecting the normal transmission of other sections of rollers. Ultimately, through the flexible control of the roller rotation state by the motor 21, combined with the coordinated cooperation of various components, the precise adjustment of the distance between conveyed objects can be achieved.

[0023] In summary, this adjustable roller drive module, through the frame 1, achieves stable assembly of the overall module structure, providing reliable support for subsequent transmission operations. By setting up a multi-roller drive structure 2, a dual-roller collaborative transmission mode is formed. Compared to the traditional single-motor driven overall transmission method, the spacing between conveyed objects can be flexibly adjusted by controlling the output speed of a single motor 21 or by coordinating multiple such modules. It also provides a basic structural support for adjusting the independent spacing of single or multiple objects, effectively improving the operational flexibility and applicability of the transmission module.
