[0001] The present application relates to the field of conveying technology, and in particular to a screening and guiding sorting conveyor belt. Background technology:

[0002] The Chinese invention patent application with application number 202310890673.8 - a one-to-three high-speed lane conveyor, includes a support leg, a frame fixed on the support leg, a driving assembly provided on one side of the frame, a driven assembly provided on the other side of the frame, the driving assembly drives the driven assembly to rotate through a synchronous belt connection, a slide plate assembly is fixed on the synchronous belt and can run along its annular track, a lane changing mechanism, an upper guide magnetic guide rail provided on the upper part of the frame, a lower guide magnetic guide rail provided on the lower part of the frame, and the upper and lower guide magnetic guide rails are respectively composed of three groups. The slide plate assembly of the present invention has no contact with the upper and lower guide magnetic guide rails, and utilizes the mutual attraction between the magnets to reliably and smoothly carry out lane conveying of materials, while effectively preventing adverse conditions such as malfunctions and the generation of noise, and can achieve one-to-three lane conveying. The present invention discloses a one-to-three high-speed lane conveyor, which relates to the field of conveying technology. The one-to-three high-speed lane conveyor includes legs, a frame fixed to the legs, a drive assembly located on one side of the frame, and a driven assembly located on the other side of the frame. The drive assembly drives the driven assembly to rotate via a synchronous belt. A slide assembly is fixed to the synchronous belt and can run along its circular trajectory. A lane-changing mechanism includes an upper magnetic guide rail located on the upper portion of the frame and a lower magnetic guide rail located on the lower portion of the frame. The upper and lower magnetic guide rails are each composed of three groups. The slide assembly of the present invention is non-contacting with the upper and lower magnetic guide rails. The mutual attraction between magnets ensures reliable and smooth material lane conveying while effectively preventing adverse conditions such as malfunctions and noise. Furthermore, one-to-three lane conveying can be achieved.

[0003] This patent uses a lane-changing mechanism to move the skateboard assembly, causing the skateboard assembly to slide according to the resistance of the magnetic guide rail, thereby achieving the function of screening and guiding. However, when the skateboard assembly slides on the round tube during operation, there is a certain amount of friction that generates high temperature, which will cause aging and damage to the skateboard and the round tube. The resistance of friction will also increase the loss and load of the magnetic guide rail. Summary of the invention:

[0004] To solve the above technical problems, the present invention provides a screening and guiding sorting conveyor belt, which solves the technical problem that the slide assembly rubs against the round tube, increasing mechanical loss and load.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will now be further described in detail with reference to the accompanying drawings and the following examples so that the public can better understand the implementation method of the present invention. The specific implementation scheme of the present invention is as follows:

[0032] Example 1:

[0033] A screening and guiding sorting conveyor belt includes a frame 1, the frame 1 is provided with a driving assembly and a driven assembly in a rotating structure, two connecting members 2 for connecting the driving assembly and the driven assembly, the two connecting members 2 are connected by a guide rod 3, a plurality of guide rods 3 are arranged at intervals along the running direction of the connecting member 2, the guide rail 3 is provided with a support plate 5 in a sliding manner, and a groove 4 connected to the guide rod 3 is opened on both sides of the support plate 5. The support plate 5 is connected to the guide rod 3 through the groove 4, and the support plate 5 can slide along the axial direction of the guide rod 3. An oil tank 7 is opened in the support plate 5. An oil passage 8 communicating with the embedded groove 4 is provided on the side wall of the oil tank 7. A shift rod 11 is provided on the inner end surface of the support plate 5. The frame 1 is provided with an upper guide rail 12, a lane changing mechanism 13 and a lower guide rail 14. The upper guide rail 12 provides a guide for the shift rod 11 to move toward the side edge of the frame 1. The lane changing mechanism 13 is used to drive the shift rod 11 to move along an upper guide rail 12, thereby controlling the running direction of the support plate 5. The lower guide rail 14 provides a guide for the shift rod 11 to move toward the middle position of the frame 1. The upper guide rail 12 and the lower guide rail 14 are both V-shaped structures and are connected to the frame 1 in a fixed structure.

[0034] By setting up an oil tank 7 for storing lubricating oil, when the support plate 5 slides, the oil seeps into the embedded groove 4 through the oil channel 8, lubricating the connection between the support plate 5 and the guide rod 3, reducing friction, and further reducing the resistance of the guide rail to the shift rod, thereby increasing the service life of the guide rail, guide rod and support plate.

[0035] Specifically, the driving assembly and the driven assembly both include a rotating shaft 15 rotatably connected to the frame 1. The rotating shaft 15 is provided with a sprocket through a flat key. The connecting member 2 is a chain. The chain and the sprocket are connected through an engaging structure. The driving assembly also includes a reduction motor for driving the rotating shaft 15 to rotate. The reduction motor is fixedly connected to the frame 1. The reduction motor drives the rotating shaft 15 at one end to rotate, and then drives the chain to drive the guide rod 3 to move.

[0036] When the guide rod 3 is in contact with the support plate 5, the number of oil tanks 7 is set to two, and the two oil tanks 7 are arranged at the left and right ends of the support plate 5; a slider 9 for blocking the oil channel 8 is provided in the oil tank 7, and the side wall of the slider 9 is connected to the side wall of the oil tank 7 in a sliding structure. A return spring 19 is provided between the slider 9 and the outer wall of the oil tank 7, and the two sliders 9 are connected by a connecting rod 10, and the connecting rod 10 is connected to the shift rod 11 in a fixed structure. A slide groove 6 for the shift rod 11 to slide is provided in the support plate 5. When the shift rod 11 is guided to both sides by the resistance of the upper guide rail 12, if the friction force is greater than the resistance force of the return spring 19, the slider 9 compresses the return spring 19, and then the oil channel 8 is opened, and the oil flows out to lubricate the guide rod 3. If the friction force is less than the resistance force of the return spring 19, the oil channel 8 is not opened, so as to prevent the oil from continuously flowing out and dripping and causing pollution to the mechanical equipment.

[0037] Furthermore, one end of the connecting rod 10 extends into the oil tank 7 and is connected to the slider 9, and a sealing ring B18 is fixedly provided on the side wall where the oil tank 7 and the connecting rod 10 are slidably connected, and a sealing ring A17 is embedded in the side wall of the oil tank 7 at the entrance of the oil channel 8 to ensure the sealing of the oil tank 7.

[0038] The working principle and working process of this embodiment are as follows:

[0039] Start the reduction motor, and drive the rotating shaft 15 at one end to rotate through the reduction motor, and then drive the chain to drive the guide rod 3 to move along the transmission direction. At this time, the goods are transferred to the pallet 5, and the pallet 5 moves along the transmission direction with the goods. The hydraulic cylinder is used to drive the shift block to turn, and then drive the shift rod 11 to one side of the upper guide rail 12. At this time, in order to overcome the friction, the shift rod 11 drives the slider 9 through the connecting rod 10 to compress the return spring 19 on one side, and the return spring 19 on the other side does not move, thereby opening the oil channel 8, and the oil flows out through the oil channel 8 for lubrication.

[0040] Example 2:

[0041] On the basis of the above embodiments, in this embodiment, a stud 20 is further provided on the side wall of the oil tank 7 by means of threaded engagement, the inner end face of the stud 20 contacts the return spring 19, a positioning plate 21 is provided on the inner side of the return spring 19, a screw 22 is fixedly provided on the positioning plate 21, the screw 22 passes through the return spring 19 and the stud 20 and extends to the outside of the oil tank 7, and a positioning nut 23 is provided on the screw 22 outside the oil tank 7 by means of threaded engagement. Since the friction between the support plate 5 and the guide rod 3 is related to the pressure of the contact surface and the roughness of the contact surface, when the roughness of the contact surface is constant, the pressure of the contact surface, that is, the weight of the consignment, is particularly important. This embodiment adjusts the elastic force of the return spring 19 by means of the positioning plate 21, the screw 22, and the positioning nut 23, and further adjusts the threshold value when the oil channel 8 is opened, thereby preventing the problem of the oil channel 8 being always open or closed.

[0042] Furthermore, the stud 20 is a hexagonal stud, and the diameter of the hexagonal stud is larger than the diameter of the positioning plate 21, which is convenient for installing the spring structure through the threaded hole. Through the threaded engagement of the stud 20 and the support plate 5, it can be ensured that when the spring force is constant, the positioning plate 21 always contacts the side wall of the slider 9 to prevent the occurrence of a neutral situation.

[0043] In order to meet the sealing requirements, a sealing ring C24 is provided on the side wall of the oil tank 7 at the stud 20, and a sealing ring D16 is provided on the side wall of the stud 20 at the screw rod 22.

[0044] The working principle and working process of the present invention are as follows:

[0045] When the cargo is light, the friction between the support plate 5 and the guide rod 3 is small, causing the return spring 19 to be unable to reach the critical value of compression, resulting in the oil channel 8 being unable to be opened. The stud 20 is rotated outward, and the positioning plate 21, the screw 22 and the return spring 19 are moved outward to a predetermined position. Then the nut 23 is rotated, and the screw 22 drives the 21 positioning plate to move inward until the positioning plate 21 contacts the slider 9. At this time, the spring is in a telescopic state, and the elastic force of the compression spring is reduced. A smaller thrust can be used to compress the return spring 19, thereby opening the oil channel 8 and allowing the oil to flow out for lubrication.
