Description

Technical Field

[0001] This utility model relates to the technical field of conveyor belt anti-jamming structure, specifically a sloping anti-jamming ball bearing rotator. Background Technology

[0002] The ball bearing fruit and vegetable sorting machine is an automated device for sorting fruits and vegetables. Its core structure consists of a chain-driven rotating shaft support, a rotating shaft, and ball bearings. During conveying, fruits and vegetables are smoothly transported through the rotation of the ball bearings and chain transmission, avoiding the collision damage of traditional vibrating screens. A vision inspection device and inclined air nozzles are installed at the top of the equipment. Image recognition technology accurately locates defective fruits and vegetables, and the air nozzles blow them downwards, causing defective products to fall through the gaps between the ball bearings to the vertical discharge mechanism, achieving non-destructive sorting. This design is particularly suitable for spherical fruits and vegetables such as cherry tomatoes and tangerines, increasing sorting efficiency by more than three times compared to manual sorting, with a breakage rate controlled below 0.5%.

[0003] In existing technologies, there are usually gaps between the balls involved in conveying, which are used to jam the material during conveying to drive the material to move. Although this structural solution can achieve material conveying, the gaps can also easily cause some material to get stuck and unable to come out. In addition, the rotation of the balls during conveying may apply pressure to the material, making the material more firmly embedded in the gaps. As more and more material gets stuck, the conveying capacity of the conveying section will be significantly reduced, so workers need to stop the equipment regularly to clean the material, which will bring many inconveniences to daily production. Therefore, to address the above problems, a sloping anti-jamming ball rotator is proposed. Utility Model Content

[0004] To address the technical problem in comparative technologies where materials easily get stuck in the gaps between the balls used for feeding in ball-type fruit and vegetable sorting machines, resulting in a significant reduction in conveying capacity and requiring workers to periodically stop the equipment for cleaning, this utility model provides a ball-rotor with an inclined surface to prevent material jamming.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A ball bearing rotator with inclined surface anti-jamming capability includes a frame with a drive chain assembly installed inside. The drive chain assembly has several arrayed ball bearings arranged in an array, forming a conveying surface for placing and conveying materials. One end of the frame's conveying surface forms an inwardly tapering inclined conveying surface. Several symmetrically arranged anti-jamming brushes are fixedly installed at the end of the frame with the inwardly tapering conveying surface, contacting the ends of the ball bearings and driving the ball bearings to rotate through friction.

[0007] In one possible implementation, the anti-jamming brush includes a bracket with a mounting plate fixed to its end by bolts, and a drive brush is snapped onto the mounting plate.

[0008] In one possible implementation, the drive brush includes a base plate that is plugged into a mounting plate, on which a plurality of abrasion-resistant industrial PPVC bristles are fixedly arranged in an array and facing the ball bearing shaft.

[0009] In one possible implementation, the ball bearing shaft includes a mounting rod on which a rotating ball assembly cylinder is fitted, wherein the ball assembly cylinder is composed of several butterfly-shaped balls and end cylinders at both ends.

[0010] In one possible implementation, a set of transmission teeth is machined on the end cylinder, the bristles of the drive brush contact the transmission teeth, and a material-holding groove is formed in the middle of the butterfly-shaped bead.

[0011] In one possible implementation, one end of each butterfly-shaped bead is provided with a insertion groove, and the other end is fixedly provided with an insertion shaft protrusion corresponding to the insertion groove. One end of one end tube is provided with an insertion groove, and the other end tube is fixedly provided with an insertion shaft protrusion.

[0012] In one possible implementation, the drive chain assembly includes several drive gear rollers rotatably mounted on the frame, and a drive motor fixedly mounted on the frame to drive the drive gear rollers to rotate, wherein all the drive gear rollers are connected by a transmission chain assembly sleeved thereon, and the mounting rod is inserted into the transmission chain assembly at both ends.

[0013] In one possible implementation, a return conveyor belt is fixedly installed at the bottom of one end of the frame with an inward inclined conveying surface, and the return conveyor belt is located directly below the anti-jamming brush.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] By using an anti-jamming brush, the drive brush on the brush can rotate the ball bearing shaft driven by the drive chain belt through contact friction. When the ball bearing shaft rotates, it can apply an outward pushing force to the material, pushing it out of the gap formed between the butterfly-shaped balls. In addition, the conveying surface at this position has an inwardly contracting inclined conveying surface. Therefore, the material falling out of the gap will not receive any support and will fall directly from the inclined conveying surface onto the return conveyor belt set below. The return conveyor belt completes the return and transports the cleaned and fallen material to the material input end. The above solution can prevent material jamming and affect the conveying capacity through self-cleaning measures. Attached Figure Description

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0024] like Figure 1 - Figure 3 As shown, this embodiment provides a ball bearing rotator with an inclined surface for preventing material jamming, including a frame 1, inside which a drive chain belt assembly 2 is installed. The drive chain belt assembly 2 is equipped with a plurality of ball bearing shafts 3 arranged in an array. All the ball bearing shafts 3 form a conveying surface for placing and conveying materials, and the conveying surface at one end of the frame 1 forms an inwardly contracting inclined conveying surface. At the end of the frame 1 with the inwardly inclined conveying surface, a plurality of symmetrically arranged anti-jamming brushes 4 are fixedly installed, which contact the ends of the ball bearing shafts 3 and drive the ball bearing shafts 3 to rotate through friction.

[0025] Based on the above scheme, when the ball bearing rod 3 is driven by the drive chain belt group 2 and passes through the anti-jamming brush 4, it will be subjected to friction and rotate. When the ball bearing rod 3 rotates, it can apply an outward pushing force to the material, pushing it out of the gap formed between the butterfly-shaped balls 321. In addition, the conveying surface at this position forms an inwardly contracting inclined conveying surface. Therefore, the material falling out of the gap will not receive any support and will fall directly from the inclined conveying surface. The above scheme can prevent jamming and affect the conveying capacity through self-cleaning measures, and can facilitate the continuous operation of the equipment.

[0026] like Figure 4 As shown, the anti-jamming brush 4 includes a bracket 41, the end of which is fixedly mounted with a mounting plate 42 by bolts. A drive brush 43 is snapped onto the mounting plate 42. The drive brush 43 includes a base plate that is plugged into the mounting plate 42. Several wear-resistant industrial PPVC bristles are fixedly arranged in an array and facing the ball bearing 3. Based on the above structural scheme, the drive brush 43 can be detached and installed as a whole through the plug-in connection between the base plate and the mounting plate 42. This allows the wear-resistant industrial PPVC bristles to be quickly removed and replaced after severe wear, significantly improving maintenance efficiency.

[0027] like Figure 4 - Figure 5 As shown, the ball bearing shaft 3 includes a mounting rod 31 on which a rotating ball bearing assembly cylinder 32 is sleeved. The ball bearing assembly cylinder 32 is composed of several butterfly-shaped balls 321 and end cylinders 322 at both ends. To achieve splicing, one end of each butterfly-shaped ball 321 is provided with an insertion groove 324, and the other end is fixedly provided with an insertion shaft protrusion 325 corresponding to the insertion groove 324. One end cylinder 322 is provided with an insertion groove 324 at one end, and the other end cylinder 322 is fixedly provided with an insertion shaft protrusion 325 at one end. The splicing connection between the butterfly-shaped balls 321 and the end cylinder 322 can be achieved through the cooperation of the insertion shaft protrusion 325 and the insertion groove 324, ensuring that the user can freely adjust the length of the ball bearing assembly cylinder 32 according to the actual situation to meet different usage needs.

[0028] Among them, such as Figure 5 As shown, a set of transmission teeth 323 are machined on the end cylinder 322. The bristles of the drive brush 43 contact the transmission teeth 323. The transmission teeth 323 can significantly enhance the friction between the end cylinder 322 and the drive brush 43, thereby enabling the drive brush 43 to better drive the entire ball joint cylinder 32 to rotate and push out the jammed material. A material jamming groove is formed in the middle of the butterfly-shaped ball 321. This material jamming groove provides the necessary structural foundation for the material conveying.

[0029] like Figure 2As shown, the drive chain assembly 2 includes several drive gear rollers 21 rotatably mounted on the frame 1, and a drive motor 22 fixedly mounted on the frame 1 to drive the drive gear rollers 21 to rotate. All the drive gear rollers 21 are connected by a transmission chain assembly 23 sleeved on them. The mounting rod 31 is inserted into the transmission chain assembly 23 at both ends. During conveying, the drive motor 22 drives the drive gear rollers 21 connected to it to rotate, thereby driving the transmission chain assembly 23 to rotate, which in turn drives the ball bearing rod 3 mounted on the transmission chain assembly 23 to move, thus completing the conveying of materials.

[0030] like Figure 1 - Figure 2 As shown, a return conveyor belt 5 is fixedly installed at the bottom of one end of the frame 1 with an inner inclined conveyor surface, and the return conveyor belt 5 is located directly below the anti-jamming brush 4. The material that falls off the inner inclined conveyor surface will fall directly onto the return conveyor belt 5. The return conveyor belt 5 completes the return and transports the cleaned material to the material input end for secondary sorting.

[0031] The working principle and usage process of this utility model:

[0032] When the ball bearing shaft 3 is driven by the drive chain belt group 2 and passes through the anti-jamming brush 4, it will rotate due to friction. When the ball bearing shaft 3 rotates, it can apply an outward pushing force to the material, pushing it out of the gap formed between the butterfly-shaped balls 321. In addition, the conveying surface at this position forms an inwardly contracting inclined conveying surface. Therefore, the material falling out of the gap will not receive any support and will fall directly from the inclined conveying surface. The above solution can prevent material jamming and affect the conveying capacity through self-cleaning measures, and facilitate the continuous operation of the equipment.

[0033] Furthermore, the material that falls off the inner inclined conveyor surface will fall directly onto the return conveyor belt 5. The return conveyor belt 5 will complete the return and transport the cleaned and fallen material to the material input end for secondary sorting, thereby improving the sorting efficiency.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
