Description

Technical Field

[0001] The present invention relates to the technical field of logistics conveying drive devices, in particular to a friction drive device. Background Art

[0002] Friction drive is a mechanical motion method that uses friction generated by two wheels in linear contact or clamping a mobile platform, creating a tight pressure to transmit power. Typically, several drive units are installed on a material conveyor line, forming a relay conveying system. Its advantages include low cost, stable operation, energy conservation and environmental protection, and ease of maintenance. It has been widely used in industries such as machinery, automotive, and logistics. Friction drive is playing an increasingly important role in modern logistics and conveying systems, providing a practical, energy-efficient, intelligent, and flexible solution.

[0003] However, existing friction drive equipment still has many technical defects. For example, it cannot adapt well to logistics and transportation equipment of different sizes. When encountering logistics and transportation equipment of different specifications, the only option is to disassemble and adjust the various components in the equipment or directly replace it with another friction drive equipment of corresponding specifications. This is undoubtedly very troublesome and time-consuming and labor-intensive. For example, existing friction drive equipment cannot fine-tune the position of the internal drive unit, resulting in the equipment being unable to adapt to changes in actual usage scenarios, which increases the difficulty of operation for staff.

[0004] For example, CN104949893B discloses a real-time intelligent detection system for a drive unit, including a main control module and a wear detection module, a drive motor power consumption measurement module and a communication module respectively connected thereto. The wear detection module detects the wear of the main drive wheel in the drive unit and transmits it to the main control module in real time. The drive motor power consumption measurement module measures the power consumption of the drive motor in the drive unit and transmits it to the main control module in real time. The main control module processes the received data to obtain the power consumption of the drive unit, and uploads the power consumption of the drive unit to the host computer through the communication module.

[0005] The above technical solution can detect various working data of the drive unit in real time, and perform early fault diagnosis and preventive maintenance based on these data, thereby improving the performance of the drive unit; however, the above device cannot make adaptive adjustments for logistics and transportation equipment of different specifications, and cannot reduce the operating difficulty of the staff.

[0006] For example, CN102070082A discloses a dual friction drive device, including a friction wheel assembly installed on the output shaft of a motor. There are two sets of motors and friction wheel assemblies, which are located on both sides of a track. A bracket is fixedly connected to the track. The motor is fixedly connected to a motor mounting plate extending along the track direction. One end of the motor mounting plate is hinged to the bracket. A pull rod assembly is arranged between the other end of the motor mounting plate and the bracket, and the other end of the motor mounting plate is supported on the roller of the roller assembly. The roller assembly is fixedly connected to the bracket.

[0007] The above technical solution adopts symmetrically arranged dual motors and dual friction wheels to drive the sling, which improves the driving force of the friction drive; the friction wheel assembly is pressed against the sling through the pull rod assembly, and the operation is reliable; the purpose of maintaining balance is achieved through the roller assembly fixed at one end of the motor mounting plate; although the application has a simple structure, easy to manufacture, and flexible operation; however, the existing friction drive equipment cannot adapt well to logistics and transportation equipment of different specifications, especially when the logistics equipment is miniaturized and the drive is achieved under limited space; the above technical solution still cannot solve this problem, and the above technical solution still has the problem that the drive unit inside the equipment cannot be adaptively adjusted according to the usage scenario.

[0008] In view of the shortcomings of the above-mentioned existing technologies, there is an urgent need for a friction drive device that can not only adapt to logistics and transportation equipment of different sizes, but also the internal drive unit can achieve fine-tuning of the position according to changes in the usage scenario, thereby improving the efficiency of driving transportation and reducing the difficulty of operation for staff; and it is more suitable for small logistics sorting equipment, with the advantages of low cost, high efficiency, easy maintenance, safety and reliability. Summary of the Invention

A one-way bearing is used in the drive unit of the present application. The one-way bearing is small in size but has a high load-bearing capacity, which reduces space usage but increases safety; there is enough space to store grease, and a longer re-lubrication interval can be achieved.

DETAILED DESCRIPTION

[0065] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0066] like Figure 1-7 As shown, the present invention proposes a friction drive device, comprising a support frame 1, an adjustment base 2, and a drive unit 3. The adjustment base 2 is mounted on the support frame 1, and the drive unit 3 is disposed on the adjustment base 2. The adjustment base 2 can fine-tune the position of the drive unit 3, and the drive unit 3 is used to drive the logistics sorting equipment to move.

[0067] The drive unit 3 includes a side plate assembly 30, a drive motor 31, a reduction gear box 32, a drive shaft 33, a drive wheel 34, a driven wheel 35, and a limit guide assembly 36; the side plate assembly 30 is fastened to the adjustment base 2 by fasteners, the reduction gear box 32 is fastened to the adjustment base 2 by fasteners, and the drive motor 31 is connected to the support frame 1 through a motor seat; the output end of the drive motor 31 is arranged in the reduction gear box 32, one end of the drive shaft 33 is arranged in the reduction gear box 32, and the output of the drive motor 31 is arranged in the reduction gear box 32. The end is connected to one end of the drive shaft 33 provided in the reduction gear box 32; the end of the drive shaft 33 away from the reduction gear box 32 is provided with a drive wheel 34, and a one-way bearing is also provided between the drive shaft 33 and the drive wheel 34, and the drive shaft 33 drives the drive wheel 34 to rotate through the one-way bearing; the drive wheel 34 and the driven wheel 35 can press the drive plate to generate driving force; a driven shaft 37 is fixedly installed under the driven wheel 35; the driven wheel is connected to the driven shaft through a bearing; the limiting guide assembly 36 is arranged between the side plate assemblies 30.

[0068] The present application provides three driven wheels, which has the advantage of being able to effectively correct the smoothness and stability of the driven part.

[0069] The drive unit 3 is installed on the adjustment base 2 through the side plate assembly 30, and the drive shaft 33 is driven to rotate by the drive motor 31. The drive motor 31 is adaptively changed in speed during operation through the reduction gear box 32, and the drive wheel 34 is driven to rotate synchronously through the drive shaft 33. The drive wheel 34 can then drive the drive plate to operate. Since the drive wheel 34 and the driven wheel 35 clamp the drive plate together at this time, the driven wheel 35 can also rotate with the rotation of the drive wheel 34. The drive wheel 34 and the driven wheel 35 drive the drive plate to move stably through the friction drive effect. Multiple friction drive devices of the present invention work together to realize the transportation work of logistics transportation equipment.

[0070] like Figure 3 、 Figure 6 As shown, the adjustment base 2 includes a longitudinal adjustment device 21 and a transverse adjustment device 22;

[0071] The longitudinal adjustment device 21 includes a first plate 23, a second plate 24, and a longitudinal adjustment rod assembly 25. The longitudinal adjustment rod assembly 25 passes through the first plate 23 and the second plate 24 at the same time. The first plate 23 and the second plate 24 can approach or move away from each other along the direction of the longitudinal adjustment rod assembly 25; the transverse adjustment device 22 includes a third plate 26 and a transverse adjustment rod 27. The transverse adjustment rod 27 passes through the second plate 24. The transverse adjustment rod 27 is slidingly connected to the second plate 24. The transverse adjustment rod 27 can be fastened to the second plate 24 by a fastener, and one end of the transverse adjustment rod 27 abuts against the third plate 26.

[0072] like Figure 2 、 Figure 6 As shown, the longitudinal adjustment rod assembly 25 includes a first rod 251 and a second rod 252;

[0073] The first rod 251 is slidably connected to the first plate 23 and the second plate 24 respectively, and the first rod 251 can be fastened to the first plate 23 and the second plate 24 by fasteners;

[0074] The second rod 252 is slidably connected to the first plate 23 and the second plate 24 respectively. The second rod 252 can be fastened to the first plate 23 and the second plate 24 by a fastener.

[0075] When it is necessary to fine-tune the position of the driving unit 3, the adjusting base 2 is controlled to work. If it is necessary to raise the driving unit 3, the second plate 24 is controlled to move away from the first plate 23. The specific steps are as follows: loosen the fasteners on the first rod 251 and the second rod 252, control the second plate 24 to move upward a corresponding distance in the direction of the first rod 251 and the second rod 252, and then tighten the fasteners on the first rod 251 and the second rod 252. After the second plate 24 rises, it can synchronously drive the third plate 26 to rise. Since the driving unit 3 is mounted on the third plate 26 through the side plate assembly 30, the rising of the third plate 26 can drive the driving unit to rise; similarly, if it is necessary to lower the driving unit 3, the third plate 24 is controlled to be close to the first plate 23. The rest of the work remains unchanged, and only the second plate 24 is changed to move downward a corresponding distance in the direction of the first rod 251 and the second rod 252. When the third plate 26 descends, the driving unit can be driven to lower its height;

[0076] When it is necessary to control the drive unit 3 to move left in the horizontal direction, loosen the fasteners on the lateral adjustment rods 27 on both sides of the third plate 26, control the third plate 26 to move to the left a corresponding distance, and then tighten the fasteners on the lateral adjustment rods 27 on both sides of the third plate 26. The third plate 26 moves to the left and synchronously drives the drive unit 3 to move to the left. Similarly, if it is necessary to control the drive unit 3 to move right in the horizontal direction, the rest of the work remains unchanged, only the distance corresponding to the right movement of the third plate 26 is changed, and the right movement of the third plate 26 synchronously drives the drive unit 3 to move right.

[0077] like Figure 2 、 Figure 3 and Figure 7 As shown, the side panel assembly 30 includes a first side panel 301 and a second side panel 302. The first side panel 301 and the second side panel 302 are respectively arranged on both sides of the third panel 26.

[0079] The driven wheel mounting bracket 38 can more conveniently drive the driven wheel 35 to move, thereby changing the distance between the driven wheel 35 and the driving wheel 34 .

[0080] like Figure 5 、 Figure 7 As shown, the limiting guide assembly 36 includes a limiting assembly and a guide assembly, and the limiting assembly includes at least one driving tensioning rod 361, and a pressing sleeve 362 and a compression spring 363 are provided on one end of the driving tensioning rod 361, and the other end of the driving tensioning rod 361 can be fastened to the first side plate 301 through a fastener; the pressing sleeve 362 can be fastened to the driving tensioning rod 361 through a fastener, and the compression spring 363 is provided between the pressing sleeve 362 and the driven wheel mounting bracket 38.

[0081] The limiting assembly of the present invention can achieve a limiting effect on the driven wheel mounting bracket 38, by abutting the driven wheel mounting bracket 38 through the compression spring 363, and utilizing the elasticity of the compression spring 363 and the limiting of the compression sleeve 362 to ensure that the driven wheel 35 can cooperate with the driving wheel 34 to firmly clamp the driving plate at the bottom of the logistics transportation equipment; when facing driving plates of different widths, the position of the driven wheel mounting bracket 38 is changed by squeezing the compression spring 363 or releasing the elasticity of the compression spring 363, thereby changing the distance between the driven wheel 35 and the driving wheel 34.

[0082] like Figure 5 、 Figure 7 As shown, the guide assembly includes at least one driving support rod 364, one end of the driving support rod 364 can be fastened to the first side plate 301 by a fastener, and the other end of the driving support rod 364 can be fastened to the second side plate 302 by a fastener; a guide sleeve 365 is also provided on the driving support rod 364, the inner part of the guide sleeve 365 is slidably connected to the driving support rod 364, and the outer part of the guide sleeve 365 is fixedly connected to the driven wheel mounting bracket 38; the driven wheel mounting bracket 38 can slide back and forth on the driving support rod 364 through the guide sleeve 365.

[0083] The guide assembly of the present invention can achieve a guiding effect on the driven wheel mounting bracket 38. When the position of the driven wheel 35 needs to be adjusted to adapt to logistics transportation equipment of different specifications, the driven wheel mounting bracket 38 can slide smoothly on the driving support rod 364 through the guide sleeve 365 to prevent the driven wheel mounting bracket 38 from deflecting during movement and affecting the driving efficiency of the drive unit 3.

[0084] A lip seal ring and a bearing are provided at the connection between the drive shaft 33 and the reduction gearbox 32 .

[0085] like Figure 2 、 Figure 4 As shown, at least one bearing seat 4 is installed on the first side plate 301, and the end of the bearing seat 4 away from the first side plate 301 is fastened to the bearing cover 5 by a fastener; the drive shaft 33 is passed between the bearing seat 4 and the bearing cover 5, and a bearing member is provided between the drive shaft 33 and the bearing seat 4. When the bearing seat 4 and the bearing cover 5 are fastened together, they can play a role in locking and limiting the drive shaft 33.

[0086] The bearing seat 4 and the bearing cover 5 are connected and fastened by fasteners. The diameter between the bearing seat 4 and the bearing cover 5 can just accommodate the drive shaft 33 and the bearing. The drive shaft 33 is locked and limited by the bearing seat 4 and the bearing cover 5 to prevent the drive shaft 33 from deviating during rotation, thereby affecting the rotation efficiency of the drive wheel 35. The bearing can ensure that the drive shaft 33 will not be affected by the roughness of the inner surface of the bearing seat 4 and the bearing cover 5.

[0087] The two or more friction drive devices can be connected to each other through the support frame 1. The two or more friction drive devices can drive the logistics sorting equipment to run a longer distance.

[0088] A plurality of friction drive devices of the present invention can work together to realize the transportation work of the logistics transportation equipment.

[0089] A friction drive device of the present invention, when in use, places the drive unit 3 at the bottom of the logistics transportation equipment, aligns the drive unit 3 with the drive plate at the bottom of the logistics transportation equipment by adjusting the base 2, and clamps the drive plate through the drive wheel 34 and the driven wheel 35, and clamps the drive plate through the limit guide assembly 36 to ensure the friction drive efficiency of the drive unit 3; then turns on the drive motor 31. The reduction box 32 performs a certain adaptive speed change on the drive motor 31 during operation, and the drive motor 31 can drive the drive shaft 33 to rotate, and the drive shaft 3 drives the drive wheel 34 to rotate synchronously, and the drive wheel 34 can then drive the drive plate to operate. Since the drive wheel 34 and the driven wheel 35 clamp the drive plate together at this time, the driven wheel 35 can also rotate with the rotation of the drive wheel 34, and the drive wheel 34 and the driven wheel 35 drive the drive plate to move stably through the friction drive effect. Multiple friction drive devices of the present invention work together to realize the transportation work of the logistics transportation equipment.

[0090] When the second plate 24 is moved downwards along the first and second rods 251 and 252, the third plate 26 can be moved upwards.

[0091] When it is necessary to control the drive unit 3 to move left in the horizontal direction, loosen the fasteners on the lateral adjustment rods 27 on both sides of the third plate 26, control the third plate 26 to move to the left a corresponding distance, and then tighten the fasteners on the lateral adjustment rods 27 on both sides of the third plate 26. The third plate 26 moves to the left and synchronously drives the drive unit 3 to move to the left. Similarly, if it is necessary to control the drive unit 3 to move right in the horizontal direction, the rest of the work remains unchanged, only the distance corresponding to the right movement of the third plate 26 is changed, and the right movement of the third plate 26 synchronously drives the drive unit 3 to move right.

[0092] Embodiment 2: When it is necessary to control the drive unit 3 to adapt to drive plates of different widths or logistics transportation equipment of different specifications, the control limit guide assembly 4 works, and the distance between the driving wheel 34 and the driven wheel 35 is changed according to the actual width of the driving plate. The specific steps are as follows: if the width of the driving plate is wider, the driven wheel mounting bracket 38 is controlled to slide on the driving support rod 364 and drive the driven wheel 35 to move synchronously. The driven wheel mounting bracket 38 is offset to the outside through the guide sleeve 365 and squeezes the compression spring under the limiting effect of the compression sleeve 362. The compression spring 363 plays an elastic limiting role on the driven wheel mounting bracket 38, abutting the driven wheel mounting bracket 38 to assist the driven wheel 35 in cooperating with the driving wheel 34 to press the driving plate; if the width of the driving plate is narrow, the elastic potential energy of the compression spring 363 is released, and the compression spring 363 synchronously pushes the driven wheel mounting bracket 38 to deflect inward, and the driven wheel mounting bracket 38 slides on the driving support rod 364 through the guide sleeve 365 and drives the driven wheel 35 to move synchronously, thereby reducing the distance between the driving wheel 34 and the driven wheel 35 to achieve the compression of the driving plate.
