Description

Technical Field

[0001] This application relates to the field of material friction traction force testing technology, and in particular to a friction traction force testing mechanism with automatic cleaning. Background Technology

[0002] Currently, the efficiency of express delivery sorting is a major bottleneck restricting the development of express delivery companies and e-commerce in my country. Traditional express delivery companies that rely heavily on manual sorting are simply unable to meet the demands of development. Manual sorting is inefficient, and with the widespread adoption of online shopping, the daily volume of express deliveries is increasing dramatically, making manual operation extremely difficult. Automated sorting systems represent a new direction for the express delivery industry.

[0003] In existing technology, operators transport packages onto a conveyor belt. The surface of the conveyor belt is equipped with several rollers that can transport the packages in the width direction of the conveyor belt. When the conveyor belt transports the packages to the designated position, the rollers transport the packages to the corresponding sorting area, thereby completing the sorting operation of the packages.

[0004] Regarding the aforementioned technologies, during the sorting process, express delivery relies on the friction between the package and the rollers. As usage time increases, dust accumulates on the roller surface, reducing the friction between the roller and the package. This prevents the package from being accurately delivered to the designated sorting area, requiring operators to re-sort the packages, resulting in low sorting accuracy. Summary of the Invention

[0005] To improve the accuracy of express delivery sorting, this application provides a friction traction force testing mechanism with automatic cleaning.

[0006] This application provides a friction traction force testing mechanism with automatic cleaning, employing the following technical solution: A friction traction force testing mechanism with automatic cleaning function includes a main body of the testing mechanism. The main body of the testing mechanism includes a support frame, a connecting frame, a sliding frame, and a friction traction force tester. The connecting frame is fixedly installed at the upper end of the support frame and is arranged along the length direction of the support frame. The sliding frame is located at the upper end of the connecting frame and is slidably connected to the connecting frame along the length direction of the connecting frame. The friction traction force tester is located between the connecting frame and the sliding frame. One end of the friction traction force tester is fixedly connected to the connecting frame, and the test end of the friction traction force tester is connected to the sliding frame. Two pulleys are rotatably connected to one side of the lower end of the support frame along the length direction. A fixing member is provided on the side of the support frame away from the pulleys. The fixing member is used to lock the support frame and the conveyor belt. A cleaning mechanism is provided on the upper end of the support frame near the input end of the conveyor belt. The cleaning mechanism cleans the rollers on the conveyor belt.

[0007] By adopting the above technical solution, when it is necessary to test the sorting force of the rollers on the conveyor belt, the support frame is placed at the upper end of the conveyor belt, and the pulley abuts against one side of the conveyor belt along its width. When it is necessary to adjust the position of the support frame, the support frame is pushed, and the pulley slides on the side of the conveyor belt. The pulley limits the support frame, so that the support frame always stays in the same position when it moves on the conveyor belt. When the position of the support frame is adjusted, the fixing component fixes the support frame. The support frame and the connecting frame cooperate to support the sliding frame. During the sorting force test, the lower end of the sliding frame abuts against the rollers on the conveyor belt. The rotation of the rollers drives the sliding frame to slide. During the sliding process, the friction traction force tester pulls the friction traction force tester. The friction traction force tester tests the friction traction force of the sliding frame. When the reading of the friction traction force tester reaches the preset value, it indicates that the roller surface is covered with dust. When the support frame moves to the next set of test positions, the cleaning mechanism cleans the roller surface, so that the roller can better sort the express delivery and improve the accuracy of express delivery sorting.

[0008] Optionally, the fastener includes two connecting plates and two fixing screws. Both connecting plates are fixedly connected to the side of the support frame away from the pulley. The fixing screws correspond one-to-one with the connecting plates, pass through the connecting plates and abut against the conveyor belt, and are threadedly connected to the connecting plates.

[0009] By adopting the above technical solution, the connecting plate and pulley work together to limit the movement of the support frame. When the position of the support frame is adjusted, the fixing screw is rotated, and the fixing screw abuts against the conveyor belt, thereby realizing the positioning of the support frame and improving the convenience of fixing the support frame to the conveyor belt.

[0010] Optionally, a number of balls are rolledly connected to both sides of the upper end of the connecting frame along the width direction, and the sliding frame abuts against the balls on both sides along the width direction, and the sliding frame and the balls are rolledly connected.

[0011] By adopting the above technical solution, the balls roll during the sliding process of the sliding frame, which helps to reduce the friction between the connecting frame and the sliding frame and improves the accuracy of the test results of the friction traction force tester.

[0012] Optionally, the upper end of the support frame has several positioning holes on the side away from the pulley. These positioning holes are arranged along the width of the support frame. The lower end of the connecting frame is fixed with a positioning rod in the vertical direction. The positioning rod is located in the positioning hole and is slidably connected to the support frame in the vertical direction. The support frame has a snap-fit ​​interface that communicates with the positioning hole. The snap-fit ​​interface is located on the side of the positioning hole near the pulley. The upper end of the positioning rod has a sliding groove in the vertical direction. The connecting frame has a through-hole in the vertical direction. The through-hole is directly opposite the sliding groove. A snap-fit ​​component is provided in the sliding groove. In the initial state, the snap-fit ​​component passes through the sliding groove and is located in the positioning hole, thereby realizing the positioning of the positioning rod and the support frame.

[0013] By adopting the above technical solution, when it is necessary to test the sorting force of other conveyor belt areas inside the support frame, the operator adjusts the snap-fit ​​component, which moves within the sliding groove and through-hole to separate the snap-fit ​​component from the snap-fit ​​interface. The operator then lifts the connecting frame, separating the positioning rod from the positioning port and inserting the positioning rod into the next positioning port. The operator then releases the snap-fit ​​component, which moves towards the positioning port, thereby achieving the positioning of the connecting frame and the support frame and improving the convenience of adjusting the position of the connecting frame.

[0014] Optionally, the snap-fit ​​component includes a sliding rod, several springs, and a snap-fit ​​block. The sliding rod passes through the through-hole and is located inside the sliding groove. The sliding rod is slidably connected to the support frame along the length of the connecting frame. The end of the sliding rod away from the support frame is located above the connecting frame. Several springs are located inside the sliding groove. In the natural state, the springs push the sliding rod to move towards the snap-fit ​​interface. The snap-fit ​​block is fixedly connected to the lower end of the sliding rod. In the initial state, the snap-fit ​​block passes through the sliding groove and is located inside the snap-fit ​​interface.

[0015] By adopting the above technical solution, when it is necessary to separate the connecting frame and the support frame, the operator pushes the sliding rod, which moves the locking block to separate it from the locking interface. When the sliding rod moves, it compresses the spring. The operator inserts the positioning rod into the adjacent positioning port. The operator releases the sliding rod, and the spring drives the sliding rod to return to its original position. The sliding rod then moves the locking block to position it within the locking interface, thus improving the convenience of separating and connecting the positioning rod from the support frame.

[0016] Optionally, the cleaning mechanism includes a rotating shaft, a rotating component, a rotating plate, several rubber rollers, and a driving component. The rotating shaft is rotatably connected to the upper end of the support frame near the input end of the conveyor belt and is arranged along the length of the connecting frame. The rotating plate is fixedly connected to the outside of the rotating shaft and is arranged along the length of the rotating shaft. The rotating component is located at the upper end of the support frame and is connected to the rotating shaft. Several rubber rollers are rotatably connected to the rotating plate. The several rubber rollers are arranged along the width of the rotating plate and along the length of the rotating plate. The driving component is located at the upper end of the rotating plate and is connected to the several rubber rollers. The driving component drives the several rubber rollers to rotate.

[0017] By adopting the above technical solution, in the initial state, the rotating plate is located above the support frame. When the rollers need to be cleaned, the rotating component drives the rotating shaft to rotate, and the rotating shaft drives the rotating plate to flip, so that the rotating plate is located on the side of the support frame near the input end of the conveyor belt. At this time, the rubber rollers abut against the rollers on the conveyor belt, and the driving component drives all the rubber rollers to rotate. The rubber rollers stick to the dust on the surface of the rollers, which improves the convenience of cleaning the rollers.

[0018] Optionally, a number of collection boxes are fixedly installed on the side of the turntable near the output end of the conveyor belt. Each collection box corresponds to a rubber roller. The collection box is located on one side of the rubber roller along the length of the turntable. A guide plate is provided between the collection box and the rubber roller. The lower end of the guide plate is fixedly connected to the upper end of the collection box, and the upper end of the guide plate abuts against the rubber roller. The guide plate is inclined from top to bottom along the direction from the rubber roller to the collection box.

[0019] By adopting the above technical solution, in the initial state, the rubber roller is in contact with the guide plate. During the rotation of the rubber roller, the guide plate removes impurities from the surface of the rubber roller. The impurities slide down the guide plate into the collection box, which improves the convenience of cleaning the surface of the rubber roller.

[0020] Optionally, the upper end of the rotating plate is provided with a positioning groove corresponding to the collection box, and the lower end of the collection box is fixed with a positioning block located in the positioning groove. The positioning block is fixed with several protrusions along the circumference, and the protrusions are made of elastic material.

[0021] By adopting the above technical solution, when installing the collection box, the positioning block is installed in the positioning groove. The protrusion and the positioning groove work together to position the collection box and the rotating plate. When it is necessary to separate the collection box from the rotating plate, since the protrusion is made of elastic material, the operator can lift the collection box upwards to complete the separation operation of the collection box and the rotating plate, which improves the convenience of assembling and disassembling the collection box.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to test the sorting force of the rollers on the conveyor belt, the support frame is placed at the upper end of the conveyor belt, and the pulley abuts against one side of the conveyor belt along the width direction. When it is necessary to adjust the position of the support frame, push the support frame, and the pulley slides on the side of the conveyor belt. The pulley limits the support frame, so that the support frame always stays in the same position when it moves on the conveyor belt. When the position of the support frame is adjusted, the fixing part fixes the support frame. The support frame and the connecting frame cooperate to support the sliding frame. During the sorting force test, the lower end of the sliding frame abuts against the rollers on the conveyor belt. The rollers rotate and drive the sliding frame to slide. During the sliding of the sliding frame, the friction traction force tester is pulled. The friction traction force tester tests the friction traction force of the sliding frame. When the reading of the friction traction force tester reaches the preset value, it indicates that the roller surface is covered with dust. When the support frame moves to the next set of test positions, the cleaning mechanism cleans the roller surface, so that the roller can sort the express delivery better and improve the accuracy of express delivery sorting. 2. When it is necessary to separate the connecting frame and the support frame, the operator pushes the sliding rod, which moves the locking block to separate it from the locking interface. As the sliding rod moves, it compresses the spring. The operator inserts the positioning rod into the adjacent positioning port. The operator releases the sliding rod, and the spring moves the sliding rod back to its original position. The sliding rod then moves the locking block to position it within the locking interface, improving the ease of separating and connecting the positioning rod from the support frame. 3. In the initial state, the rotating plate is located above the support frame. When the rollers need to be cleaned, the rotating component drives the rotating shaft to rotate, and the rotating shaft drives the rotating plate to flip, so that the rotating plate is located on the side of the support frame closer to the input end of the conveyor belt. At this time, the rubber rollers are in contact with the rollers on the conveyor belt, and the driving component drives all the rubber rollers to rotate. The rubber rollers stick to the dust on the surface of the rollers, which improves the convenience of cleaning the rollers. Attached Figure Description

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a friction traction force testing mechanism with automatic cleaning capabilities.

[0031] Example: Reference Figure 1 A friction traction force testing mechanism with automatic cleaning function includes a testing mechanism body 1. The testing mechanism body 1 includes a support frame 11, a connecting frame 12, a sliding frame 13, and a friction traction force tester 14. The support frame 11 is placed on the upper end face of the conveyor belt and can slide back and forth along the conveyor belt conveying direction. Two pulleys 15 are rotatably connected to one side of the lower end of the support frame 11 along the length direction. When it is necessary to test the sorting force of the rollers on the conveyor belt, the support frame 11 is placed on the upper end of the conveyor belt, and the pulleys 15 abut against one side of the conveyor belt along the width direction. When it is necessary to adjust the position of the support frame 11, the support frame 11 is pushed, and the pulleys 15 slide on the side of the conveyor belt. The pulleys 15 limit the support frame 11 so that the support frame 11 is always in the same position when it moves on the conveyor belt.

[0032] Reference Figure 1 A fixing member 2 is provided on the side of the support frame 11 away from the pulley 15. When the position of the support frame 11 is adjusted, the fixing member 2 fixes the support frame 11. The fixing member 2 includes two connecting plates 21 and two fixing screws 22. The two connecting plates 21 are fixedly connected to the side of the support frame 11 away from the pulley 15. The connecting plates 21 and the pulley 15 cooperate to limit the movement of the support frame 11. The fixing screws 22 correspond one-to-one with the connecting plates 21. The fixing screws 22 pass through the connecting plates 21 and abut against the conveyor belt. The fixing screws 22 are threadedly connected to the connecting plates 21. When the position of the support frame 11 is adjusted, the fixing screws 22 are rotated, and the fixing screws 22 abut against the conveyor belt, thereby achieving the fixed positioning of the support frame 11.

[0033] Reference Figure 1 A connecting frame 12 is fixedly mounted on the upper end of a support frame 11. The connecting frame 12 is slidably connected to the support frame 11 along the conveyor belt conveying direction and is set along the length of the support frame 11. A sliding frame 13 is located on the upper end of the connecting frame 12 and is slidably connected to the connecting frame 12 along the length of the connecting frame 12. The support frame 11 and the connecting frame 12 cooperate to support the sliding frame 13. During the sorting force test, the lower end of the sliding frame 13 abuts against the rollers on the conveyor belt, and the rotation of the rollers causes the sliding frame 13 to slide. A friction traction force tester 14 is located between the connecting frame 12 and the sliding frame 13. One end of the friction traction force tester 14 is fixedly connected to the connecting frame 12, and the test end of the friction traction force tester 14 is connected to the sliding frame 13. During the sliding process of the sliding frame 13, the friction traction force tester 14 is pulled, and the friction traction force tester 14 tests the friction traction force of the sliding frame 13. When the reading of the friction traction force tester 14 reaches the preset value, it indicates that the surface of the roller is covered with dust.

[0034] Reference Figure 2Multiple balls 16 are rolledly connected to both sides of the upper end of the connecting frame 12 along the width direction. Both sides of the sliding frame 13 along the width direction abut against the balls 16. The sliding frame 13 is rolledly connected to the balls 16. During the sliding process of the sliding frame 13, the balls 16 roll, which helps to reduce the friction between the connecting frame 12 and the sliding frame 13 and improves the accuracy of the test results of the friction traction force tester 14.

[0035] Reference Figure 1 and Figure 3 The support frame 11 has multiple positioning ports 111 on the upper end away from the pulley 15. These ports are arranged along the width of the support frame 11. A positioning rod 121 is vertically fixed to the lower end of the connecting frame 12. The positioning rod 121 is located within the positioning port 111 and is slidably connected to the support frame 11 vertically. The positioning rod 121 cooperates with the support frame 11 to limit the movement of the connecting frame 12. The support frame 11 has a locking interface 112 connected to the positioning port 111. The locking interface 112 is located on the side of the positioning port 111 closest to the pulley 15. A sliding groove 122 is vertically opened at the upper end of the positioning rod 121. The connecting frame 12 has a through-hole 123 vertically opened, directly opposite the sliding groove 122. A locking member 17 is provided within the sliding groove 122. When it is necessary to test the sorting force of other conveyor belt areas inside the support frame 11, the operator adjusts the locking member. Part 17, the snap-fit ​​part 17 moves within the sliding groove 122 and the through port 123, causing the snap-fit ​​part 17 to separate from the snap-fit ​​interface 112. The operator lifts the connecting frame 12, the positioning rod 121 separates from the positioning port 111, and inserts the positioning rod 121 into the next positioning port 111. The operator releases the snap-fit ​​part 17, and the snap-fit ​​part 17 moves towards the positioning port 111, thereby realizing the positioning of the connecting frame 12 and the support frame 11, improving the convenience of adjusting the position of the connecting frame 12.

[0036] Reference Figure 1 and Figure 3The snap-fit ​​component 17 includes a sliding rod 171, multiple springs 172, and a snap-fit ​​block 173. The sliding rod 171 passes through the through-hole 123 and is located inside the sliding groove 122. The sliding rod 171 is slidably connected to the support frame 11 along the length of the connecting frame 12 and slidably connected to the connecting frame 12 vertically. The end of the sliding rod 171 away from the support frame 11 is located above the connecting frame 12. The multiple springs 172 are all located inside the sliding groove 122. In its natural state, the springs 172 push the sliding rod 171 to move towards the snap-fit ​​interface 112. The snap-fit ​​block 173 is fixedly connected to the lower end of the sliding rod 171. In the initial state, the snap-fit... Block 173 passes through the sliding groove 122 and is located inside the card interface 112. When it is necessary to separate the connecting frame 12 and the support frame 11, the operator pushes the sliding rod 171. The sliding rod 171 drives the card block 173 to move, so that the card block 173 is separated from the card interface 112. When the sliding rod 171 moves, it squeezes the spring 172. The operator inserts the positioning rod 121 into the adjacent positioning port 111. The operator releases the sliding rod 171, and the spring 172 drives the sliding rod 171 to reset. The sliding rod 171 drives the card block 173 to move, so that the card block 173 is located inside the card interface 112.

[0037] Reference Figure 1 and Figure 4 A cleaning mechanism 3 is provided on the upper end of the support frame 11 near the input end of the conveyor belt. The cleaning mechanism 3 cleans the surface of the rollers, enabling the rollers to better sort the express packages. The cleaning mechanism 3 includes a rotating shaft 31, a rotating component 32, a rotating plate 33, multiple rubber rollers 34, and a driving component 35. The rotating shaft 31 is rotatably connected to the upper end of the support frame 11 near the input end of the conveyor belt and is arranged along the length of the connecting frame 12. The rotating plate 33 is fixedly connected to the outside of the rotating shaft 31 and is arranged along the length of the rotating shaft 31. The rotating component 32 is located at the upper end of the support frame 11 and is connected to the rotating shaft 31. The rotating component 32 can be a combination structure of a motor and a gear set. In the initial state, the rotating plate 33 is located above the support frame 11. When it is necessary to clean the rollers, the rotating component 32 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the rotating plate 33 to flip, so that the rotating plate 33 is located on the side of the support frame 11 near the input end of the conveyor belt.

[0038] Reference Figure 4 Multiple rubber rollers 34 are rotatably connected to the rotating plate 33. The multiple rubber rollers 34 are arranged along the width direction of the rotating plate 33 and along the length direction of the rotating plate 33. The driving component 35 is located at the upper end of the rotating plate 33 and is connected to the multiple rubber rollers 34. The driving component 35 can be a combination structure of a motor and multiple belts. The rubber rollers 34 abut against the rollers on the conveyor belt. The driving component 35 drives all the rubber rollers 34 to rotate. The rubber rollers 34 adhere to the dust on the surface of the rollers, which improves the convenience of cleaning the rollers.

[0039] Reference Figure 4 and Figure 5 Multiple collection boxes 36 are fixedly installed on one side of the turntable 33 near the output end of the conveyor belt. Each collection box 36 corresponds to a rubber roller 34. The collection box 36 is located on one side of the rubber roller 34 along the length of the turntable 33. A guide plate 37 is provided between the collection box 36 and the rubber roller 34. The lower end of the guide plate 37 is fixedly connected to the upper end of the collection box 36, and the upper end of the guide plate 37 abuts against the rubber roller 34. The guide plate 37 is inclined from top to bottom along the direction from the rubber roller 34 to the collection box 36. In the initial state, the rubber roller 34 is in contact with the guide plate 37. During the rotation of the rubber roller 34, the guide plate 37 removes impurities from the surface of the rubber roller 34. The impurities slide down the guide plate 37 into the collection box 36.

[0040] Reference Figure 5 The upper end of the rotating plate 33 is provided with a positioning groove 38 corresponding to the collection box 36. The lower end of the collection box 36 is fixed with a positioning block 361, which is located in the positioning groove 38. The positioning block 361 is fixed with multiple protrusions 362 along the circumference. The protrusions 362 are made of elastic material. When the collection box 36 is installed, the positioning block 361 is installed in the positioning groove 38. The protrusions 362 and the positioning groove 38 cooperate to position the collection box 36 and the rotating plate 33. When it is necessary to separate the collection box 36 from the rotating plate 33, since the protrusions 362 are made of elastic material, the operator can lift the collection box 36 upward to complete the separation operation of the collection box 36 from the rotating plate 33, which improves the convenience of assembling and disassembling the collection box 36.

[0041] The implementation principle of the friction traction force testing mechanism with automatic cleaning in this application embodiment is as follows: When it is necessary to test the sorting force of the rollers on the conveyor belt, the lower end of the sliding frame 13 abuts against the rollers on the conveyor belt. The rollers rotate, causing the sliding frame 13 to slide. During the sliding process, the sliding frame 13 pulls the friction traction force tester 14. The friction traction force tester 14 tests the friction traction force of the sliding frame 13. When the reading of the friction traction force tester 14 reaches the preset value, it indicates that the roller surface is covered with dust. When the support frame 11 moves to the next set of test positions, the rotating component 32 drives the rotating shaft 31 to rotate. The rotating shaft 31 carries... The rotating plate 33 flips over, positioning it on the side of the support frame 11 near the input end of the conveyor belt. At this point, the rubber rollers 34 come into contact with the rollers on the conveyor belt. The drive unit 35 drives all the rubber rollers 34 to rotate, allowing the rubber rollers 34 to adhere to the dust on their surfaces. During the rotation of the rubber rollers 34, the guide plate 37 removes impurities from their surfaces, which then slide down the guide plate 37 into the collection box 36. This device can promptly clean the rollers when it detects dust on their surfaces, enabling express deliveries to be accurately delivered to their designated locations without the need for secondary sorting by operators, thus improving the accuracy of express delivery sorting.
