Description

Technical Field

[0001] This utility model relates to the field of sorting and refining devices, and in particular to a reversing roller for a logistics sorting and refining device. Background Technology

[0002] In the modern logistics industry, sorting is a crucial link, and efficient and accurate sorting is of great significance for improving logistics efficiency and reducing costs. In logistics sorting equipment, rollers are key components for conveying objects, and their performance and function directly affect the sorting effect.

[0003] Traditional logistics sorting equipment typically requires multiple rollers to sort objects of varying weights. These rollers often occupy a significant amount of space, increasing the size and cost of the equipment, making its structure more complex, and causing inconvenience in installation and maintenance. Moreover, the multiple rollers can lead to a cumbersome sorting process and reduced sorting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a reversing roller for a logistics sorting device to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A reversing roller for a logistics sorting device includes:

[0007] A bracket, the top of which is rotatably connected to a roller body;

[0008] A round rod is fixedly connected to the bottom end of the bracket, and a limit post is provided on one side of the round rod to limit the movement of the round rod;

[0009] A sleeve is fitted onto the top end of a round rod, and a spiral hole is provided on the outer side of the sleeve, with the limiting post passing through the spiral hole;

[0010] The first disc is fixedly connected to the bottom end of the round rod, and a spring is provided at the top end of the first disc. One end of the spring is fixedly connected to the bottom end of the sleeve, and the spring is sleeved on the bottom end of the round rod.

[0011] By adopting the above technical solution, the roller body can be reversed according to the different weights of the objects to be conveyed, thereby separating them into different categories. This saves a lot of space and eliminates the need to set up multiple different rollers to achieve the separation effect.

[0012] In a further embodiment, the support includes:

[0013] Support rods, wherein multiple support rods are provided, the support rods have the same structure, and the support rods are symmetrically arranged on the left and right sides of the top of the round rod;

[0014] The first rotating shaft has two ends fixedly connected to the support rod on the side that are close to each other, and the first rotating shaft is rotatably connected to the roller body.

[0015] In a further embodiment, the roller body includes:

[0016] The second disk, multiple second disks are provided, the second disks have the same structure, multiple mounting grooves are provided on the periphery of the second disk, and a through hole is provided at the center of the left end of the second disk, and the first rotating shaft passes through the through hole;

[0017] The second rotating shaft is fixedly connected in the mounting groove;

[0018] The third disk has a through-hole at its front end, and the second rotating shaft passes through the through-hole of the third disk.

[0019] In a further embodiment, the second rotating shaft is arranged perpendicular to the first rotating shaft, and the axis of the third disk is arranged perpendicular to the axis of the second disk.

[0020] In a further embodiment, a buffer washer is provided at the bottom end of the first disk, a wear-resistant coating is provided on the outer surface of the sleeve, and a lubricating layer is provided on the inner wall of the sleeve.

[0021] In a further embodiment, a self-lubricating bearing is embedded in the clearance hole of the third disk, and the self-lubricating bearing is clearance-fitted with the second rotating shaft.

[0022] In a further embodiment, the diameter of the first disk is larger than the diameter of the rod, and the end of the limiting post is provided with a ball bearing, which makes rolling contact with the helical hole.

[0023] By adopting the above technical solution, when transporting light objects, the spring force is sufficient to support the movement of the object, allowing it to move normally in a straight line. When the weight of the object exceeds the spring force, the roller body moves downward, causing the round rod to move downward as well. The limiting post on one side of the round rod moves downward along with the round rod. Because the limiting post passes through the spiral hole of the sleeve, the round rod rotates simultaneously during its downward movement, causing the bracket at the top of the round rod to rotate along with the round rod, thus rotating the roller body as well. This allows for the sorting of heavy objects. By changing the rolling direction of the roller body, space is saved in the sorting device, eliminating the need for multiple rollers in different directions to achieve the sorting effect. A third disc is provided on the roller body, with its axis perpendicular to the axis of the second disc. This allows for the reversal of movement of lighter objects when the spring cannot be triggered, preventing the roller body from rotating and changing direction. This increases the applicability of the object and allows for the adjustment of the pressure value of the roller body for reversal by changing the spring.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. When transporting light objects, the spring force is sufficient to support the movement of the object, allowing it to move normally in a straight line. When the weight of the object exceeds the spring force, the roller body moves downward, causing the round rod to move downward as well. A limiting post on one side of the round rod moves downward along with the rod. Because the limiting post passes through the spiral hole of the sleeve, the round rod rotates simultaneously during its downward movement, causing the bracket at the top of the round rod to rotate as well, thus rotating the roller body as well. This allows for the sorting of heavier objects. By changing the rolling direction of the roller body, space is saved in the sorting device, eliminating the need for multiple rollers in different directions to achieve the sorting effect. A third disc is provided on the roller body, with its axis perpendicular to the axis of the second disc. This allows for the reversal of movement of lighter objects when the spring cannot be triggered, preventing the roller body from rotating and changing direction. This increases the applicability of the object and allows for the adjustment of the pressure value of the roller body for reversal by changing the spring. Attached Figure Description

[0031] Example 1:

[0032] like Figures 1-2 As shown, a reversing roller for a logistics sorting device includes a bracket 1, a round rod 3, a sleeve 5, and a first disc 6. The top of the bracket 1 is rotatably connected to the roller body 2. The round rod 3 is fixedly connected to the bottom of the bracket 1. A limit post 4 is provided on one side of the round rod 3 to limit the movement of the round rod 3. The sleeve 5 is sleeved on the top of the round rod 3. A spiral hole is provided on the outside of the sleeve 5. The left end of the spiral hole is located at the front end of the sleeve 5, and the right end of the spiral hole is located at the right end of the sleeve 5. The distance between the left end of the spiral hole and the bottom end of the sleeve 5 is less than the distance between the right end of the spiral hole and the bottom end of the sleeve 5. The limit post 4 passes through the spiral hole and slides freely in the spiral hole. The first disc 6 is fixedly connected to the bottom of the round rod 3. A spring 7 is provided on the top of the first disc 6. One end of the spring 7 is fixedly connected to the bottom end of the sleeve 5. The spring 7 is sleeved on the bottom end of the round rod 3.

[0033] The bracket 1 includes support rods 11 and a first rotating shaft 12. Multiple support rods 11 are provided, and two support rods 11 are provided. The support rods 11 have the same structure and are symmetrically arranged on the left and right sides of the top of the round rod 3. The two ends of the first rotating shaft 12 are respectively fixedly connected to the side of the support rods 11 that are close to each other. The first rotating shaft 12 is rotatably connected to the roller body 2.

[0034] The roller body 2 includes a second disc 21, a second rotating shaft 22, and a third disc 23. Multiple second discs 21 are provided, with two second discs 21 having the same structure. Multiple mounting slots are provided around the periphery of the second disc 21, with a total of four mounting slots. A through hole is provided at the center of the left end of the second disc 21, through which the first rotating shaft 12 passes. Multiple second rotating shafts 22 are provided, with a total of four second rotating shafts 22, which are fixedly connected to the mounting slots. A clearance hole is provided at the front end of the third disc 23, through which the second rotating shaft 22 passes.

[0035] The axis of the second rotating shaft 22 is perpendicular to the axis of the first rotating shaft 12. The axis of the third disc 23 is perpendicular to the axis of the second disc 21. A buffer washer is provided at the bottom of the first disc 6. A wear-resistant coating is provided on the outer surface of the sleeve 5. A lubrication layer is provided on the inner wall of the sleeve 5. A self-lubricating bearing is embedded in the clearance hole of the third disc 23. The self-lubricating bearing is clearance-fitted with the second rotating shaft 22. The diameter of the first disc 6 is larger than the diameter of the round rod 3. A ball bearing is provided at the end of the limiting post 4. The ball bearing is in rolling contact with the spiral hole.

[0036] Specific implementation process: When transporting light objects, the elastic force of spring 7 is sufficient to support the movement of the object, allowing it to move normally in a straight line. When the weight of the object exceeds the elastic force of spring 7, the roller body 2 moves downward, causing the round rod 3 to move downward. The limiting post 4 on one side of the round rod 3 moves downward along with the round rod 3. Because the limiting post 4 passes through the spiral hole of the sleeve 5, the round rod 3 rotates simultaneously during its downward movement, thereby causing the support 1 at the top of the round rod 3 to rotate along with the round rod 3, causing the roller body 2 to also rotate. This allows the heavy objects to be sorted. By changing the rolling direction of the roller body 2, space is saved in the sorting device, eliminating the need for multiple rollers in different directions to achieve the sorting of objects. A third disc 23 is provided on the roller body 2, with its axis perpendicular to the axis of the second disc 21. This allows the third disc 23 to move lighter objects in a different direction when the spring 7 cannot be triggered, thus preventing the roller body 2 from rotating and changing direction. This increases the applicability of the objects, and the pressure value of the roller body 2 for reversing direction can be changed by altering the spring 7.
