Description

Technical Field

[0001] The utility model relates to the technical field of sorting machines, and particularly relates to a driving roller transmission mechanism for a sorting machine. Background Technique

[0002] As the core component of an automatic sorting system, the performance of a sorting machine directly affects the operation efficiency and stability of the entire production line.

[0003] Traditional sorting machines usually include multiple pairs of driving rollers and driven rollers used in combination. The driving rollers are arranged below, and the driven rollers are arranged above. The driving rollers and the driven rollers are connected by a polyurethane round belt. The driven rollers are responsible for carrying and diverting the conveyed workpieces. In order to meet the functional requirements of conveying and diverting, the sorting machine needs to perform frequent swing switching during actual operation. The polyurethane round belt is always in a state of being stretched and then rebounded within a certain range. Prolonged high-load operation in a low-temperature environment will cause the polyurethane round belt to fatigue and break, resulting in production interruption and equipment damage. Due to the wear and breakage of the polyurethane round belt and the guide wheels, they need to be replaced regularly, which increases the maintenance cost and downtime. In this case, due to structural limitations of the existing traditional sorting machines, replacing the polyurethane round belt requires disassembling the entire machine. This process is not only time-consuming and laborious, but also increases the complexity and cost of maintenance. Therefore, it is necessary to improve the corresponding roller transmission mechanism. Content of the Utility Model

[0024] To solve the above technical problems, as Figure 1-6As shown in the figure, the utility model designs a driving roller conduction mechanism for a sorting machine, which includes a mounting plate 1, a driving roller conduction mechanism 2, a synchronous driving mechanism 3, and an angle adjustment mechanism 4. The mounting plate 1 is used to connect with the equipment frame. Four driving roller conduction mechanisms 2 are arranged above the mounting plate 1 and are located at the four corners respectively. The driving roller conduction mechanism 2 is used to conduct workpieces. The mounting plate 1 is fixed on the equipment frame by bolts. The four driving roller conduction mechanisms 2 are evenly distributed at the four corners of the mounting plate 1, ensuring the balance and stability of the sorting machine. The driving roller conduction mechanism 2 includes a driving roller group. Each driving roller group includes two long rollers 21 arranged in parallel and two short rollers 22. The synchronous driving mechanism 3 is used to drive the driving roller groups of each driving roller conduction mechanism 2 to run synchronously. The angle adjustment mechanism 4 is used to synchronously adjust the angles of each driving roller group.

[0025] Specifically, the active roller conduction mechanism 2 further includes a belt pulley drive assembly. Each long roller 21 is connected to a coaxially fitted first support shaft 23, and each short roller 22 is connected to a coaxially fitted second support shaft 24. The two first support shafts 23 and the two second support shafts 24 are arranged in parallel, and the two first support shafts 23 are located inside the two second support shafts 24. The first support shaft 23 and the second support shaft 24 are synchronously driven through the belt pulley drive assembly. Preferably, the belt pulley drive assembly includes a bottom plate 25, a top plate 26, a limit flange 27, a drive shaft 28, a driven shaft 29, a first synchronous pulley 210, a second synchronous pulley 211, a tension adjustment pulley 212, a third synchronous pulley 213, and a first synchronous belt 214. The flange of the limit flange 27 is fixedly connected to the mounting plate 1. The drive shaft 28 passes through the inner hole of the limit flange 27. The synchronous drive mechanism 3 is connected to the drive shaft 28 and transmits power to the drive shaft 28. The top of the drive shaft 28 is connected to an actively engaged bevel gear 215 coaxially and fixedly. The top plate 26 and the bottom plate 25 are arranged opposite to each other up and down, and a first support frame 216 and a second support frame 217 are provided therebetween. The first support shaft is installed on the first support frame 216, and the second support shaft is installed on the second support frame 217. The two ends of the driven shaft 29 are rotatably fitted with the first support frame 216. The driven shaft 29 is provided with a driven bevel gear 218 that meshes with the actively engaged bevel gear 215. One end of each first support shaft 23 is connected to a first synchronous pulley 210, and one end of each second support shaft 24 is connected to a second synchronous pulley 211. One end of the driven shaft 29 is provided with a third synchronous pulley 213 coaxially. A tension adjustment pulley 212 is installed on one side of the first support frame 216. The third synchronous pulley 213 and the tension adjustment pulley 212 are arranged parallel to each other up and down. The axial direction of the third synchronous pulley 213 coincides with the central symmetry plane of the two first synchronous pulleys 210. The first synchronous belt 214 is used to connect the first synchronous pulley 210, the second synchronous pulley 211, the third synchronous pulley 213, and the tension adjustment pulley 212 and enable synchronous rotation. Through the belt pulley drive assembly, synchronous drive is achieved. The inclined wheel sorting machine of the present utility model ensures the synchronous operation of the long roller 21 and the short roller 22, improves the accuracy and reliability of transmission. On the one hand, the design of the belt pulley drive assembly ensures the tension of the synchronous belt and the stability of transmission through precise matching and adjustment. On the other hand, the separation design of the belt and the guide wheel avoids the slipping phenomenon, ensures that the roller can operate continuously, makes the guide wheel and the transmission mechanism more durable, reduces the replacement frequency caused by wear, and thus extends the service life of the sorting machine.

[0026] In addition, the inclined wheel sorter of the present utility model adopts a modular design. The active roller conveyor mechanism 2 can be quickly disassembled and replaced individually without disassembling the whole machine, which greatly simplifies the maintenance process, reduces the maintenance difficulty and cost. The modular and easy-to-maintain design makes the sorter easy to integrate with other automated equipment and is convenient for expansion and upgrade according to production requirements. At the same time, due to the easy maintainability of the guide wheels and transmission mechanisms, maintenance personnel can quickly troubleshoot faults and replace components, reducing the equipment downtime and production losses caused by maintenance.

[0027] Furthermore, the top plate 26 is provided with a through groove for exposing the long rollers 21 and the short rollers 22 to the upper part. The design of the through groove enables the rollers to play a normal guiding and transporting role, while the top plate 26 can protect the internal structure below.

[0028] Furthermore, two inner bearings 219 are provided between the drive shaft 28 and the limit flange 27, and an outer bearing 220 is provided between the support seat 221 and the straight cylinder part of the limit flange 27. The use of the inner bearings 219 and the outer bearings 220 reduces the friction of the drive shaft 28 and the support seat 221 during operation, improving the operation efficiency and durability of the sorter.

[0029] Furthermore, the synchronous drive mechanism 3 includes a fourth synchronous pulley 31, a drive motor assembly 32, a drive wheel 33, and a second synchronous belt 34. One side of the mounting plate 1 is provided with a fixing plate, and the drive motor assembly 32 is mounted on the fixing plate. The output shaft of the drive motor assembly 32 is vertically downward and connected with a drive wheel 33. The bottom end of each drive shaft 28 is connected with a coaxially fitted and fixed fourth synchronous pulley 31. The drive wheel 33 and the fourth synchronous pulley 31 are connected by the second synchronous belt 34. The second synchronous belt 34 is located below the mounting plate 1. By adopting the synchronous drive mechanism 3 to replace the traditional single-belt drive mode, the inclined wheel sorter of the present utility model can ensure the synchronous operation of each active roller group, avoiding the problem of reduced transmission efficiency caused by belt wear, breakage or slipping, and significantly improving the operation efficiency and reliability of the sorter.

[0030] Furthermore, the active roller transmission mechanism 2 further includes a support base 221. The support base 221 is fixedly connected to the bottom plate 25. The support base 221 is sleeved on the straight cylinder part of the limit flange 27 and is rotationally matched therewith. The angle adjustment mechanism 4 includes a cylinder 41, a linkage plate 42, a linkage arm 43, a first linkage shaft 44, and a second linkage shaft 45. The cylinder 41 is arranged below the mounting plate 1. The cylinder body of the cylinder 41 is rotationally connected to the mounting plate 1 through a positioning shaft. The piston rod of the cylinder 41 is connected to the first linkage shaft 44. The mounting plate 1 is provided with a kidney-shaped limit hole. The first linkage shaft 44 passes through the kidney-shaped limit hole and is connected to the linkage plate 42 located above the mounting plate 1. A second linkage shaft 45 is respectively arranged at the four corners of the linkage plate 42. Each support base 221 is fixedly connected to a linkage arm 43. The other end of each linkage arm 43 is rotationally matched with the second linkage shaft 45. The cylinder 41 is used to drive each linkage arm 43 to rotate synchronously through the linkage plate 42, thereby pulling the support base 221 to rotate a certain angle. The angle adjustment mechanism 4 allows for precise control of the roller angle, can quickly adapt to branch conveyor lines at different angles, enables the production line to quickly adjust the sorting direction according to production requirements, improves the flexibility and response speed of production, ensures that workpieces can accurately enter the predetermined conveyor line during the sorting process, improves the accuracy and reliability of sorting. The fast and simple angle adjustment mechanism reduces the time required for equipment adjustment, enabling the sorter to quickly adapt to changes in the production line. At the same time, since it can adapt to conveyor lines at different angles, the sorter of the present utility model can be integrated with various types of production lines and conveying systems, improving the compatibility of the equipment and the market application range.

[0031] In addition, the automated angle adjustment reduces the need for manual adjustment, reduces the labor intensity of operators, and at the same time reduces sorting errors caused by improper manual adjustment. The automated angle adjustment mechanism 4 reduces the chance of operators coming into contact with moving parts during the adjustment process, thereby improving the safety of operation.

[0032] Furthermore, a passive roller transmission mechanism 5 is further included. The passive roller transmission mechanism 5 is arranged at the center of the four active roller transmission mechanisms 2. The passive roller transmission mechanism 5 is connected to the linkage plate 42. The setting of the passive roller transmission mechanism 5 improves the stability and reliability of the sorter during the sorting process, and the connection with the linkage plate 42 provides better collaborative working ability.
