Description

Technical Field

[0001] This utility model relates to the technical field of ball bearing conveying equipment, specifically a ball bearing conveying device. Background Technology

[0002] Ball bearing fruit and vegetable conveyor systems are devices that transport fruits and vegetables through the rolling of balls. They offer advantages such as smooth conveying, reduced damage, and strong adaptability, making them suitable for fruit and vegetable processing scenarios requiring precise sorting, gentle handling, or flexible layout. The system uses a conveying surface composed of densely arranged balls, which move the fruits and vegetables by their free rolling motion. Its core structure includes: ball bearing components made of highly wear-resistant and corrosion-resistant materials (such as stainless steel or engineering plastics); a drive system that uses a motor to drive a chain or belt to rotate the balls, achieving automated conveying; and a frame design with a modular frame that allows for flexible adjustment of length and angle to adapt to different production line layout requirements.

[0003] The invention disclosed in CN109225908B is a fruit and vegetable sorting machine, which includes a conveying mechanism, an image acquisition device, a fruit and vegetable turning mechanism, multiple sorting channels, a top-out device, and a central control system. The conveying mechanism adopts a ball bearing conveying device. The conveyor belt includes a conveying chain, multiple shafts fixed at equal intervals to the conveying chain, and ball bearings installed on the shafts. Two adjacent ball bearings form a conveying group. Each ball bearing group includes multiple balls connected end to end. Each ball bearing includes a concave ring that slopes from both ends of the ball bearing towards the middle. Two corresponding balls on two adjacent ball bearing groups form a conveying unit. The above structure can form several conveying channels for positioning and conveying fruits and vegetables.

[0004] In the aforementioned ball-type conveyor equipment, because the balls are independent of each other and lack a strong and reliable connection, they cannot form a whole. Therefore, during the operation of the equipment, the balls are prone to separation and displacement, which causes changes in the size of the material groove formed between the balls, resulting in material leakage and ineffective material jamming. In addition, since the transmission gear is close to the balls, dust and debris carried on the material can easily fall off the balls during transportation and come into direct contact with the transmission gear, causing additional wear on the transmission gear during transmission and even directly causing transmission system failure. Therefore, to address the above problems, a ball-type conveyor equipment is proposed. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a ball-bearing conveyor device. In this device, the two ends of the ball body are respectively equipped with matching hexagonal connectors and riveting components. Adjacent ball bodies are fixedly connected by these connectors. This structure provides a stable and reliable connection, ensuring that the ball bodies in the same group are tightly connected to form a whole, guaranteeing that the size of the groove formed between the ball bodies remains unchanged, thus improving the conveying effect. Furthermore, an anti-jamming transmission component is connected to the end of the ball body. This component provides both transmission and transition isolation, preventing dust and debris on the material from directly contacting the rotating drive assembly and drive mechanism when it falls off. This avoids situations where the drive structure is jammed, causing the entire device to malfunction. This solves the technical problems of comparative technologies where the ball bodies are independent and cannot form a whole, easily separating and shifting during operation, leading to changes in the size of the material groove, resulting in material leakage and ineffective material jamming. It also addresses the issue of transmission gears being close to the ball bodies, causing dust and debris on the material to directly contact the transmission gears when falling off, easily leading to transmission system failure.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A ball-type conveying device includes a frame with a transmission chain mechanism installed inside. Several sets of ball-type conveying mechanisms are arranged in an array on the transmission chain mechanism. A drive mechanism drives the transmission chain mechanism. A drive motor drives the drive mechanism. A rotation drive assembly drives the contacting ball-type conveying mechanisms to rotate. Each ball-type conveying mechanism includes a central shaft with several sets of ball bodies mounted on it. An anti-jamming transmission component that fits against the ball bodies is installed at the end of the central shaft. Matching hexagonal connectors are provided at both ends of each ball body. The ball bearings are fixedly connected to each other by hexagonal connectors and rivets. The above structure can provide a stable and reliable connection so that the ball bearings in the same group are tightly connected to form a whole. This ensures that the size of the groove formed between the ball bearings remains unchanged, improving the conveying effect. In addition, the anti-jamming transmission component can provide a transition isolation function while realizing the transmission function. It can prevent dust and debris on the material from directly contacting the rotating drive component and drive mechanism when they fall off, avoiding the situation where the drive structure is jammed and the entire equipment cannot function.

[0008] In one possible implementation, the hexagonal connector includes a hexagonal plug and a hexagonal insert, which are respectively disposed at both ends of the ball body. When the ball bodies are connected to each other, the hexagonal plug and the hexagonal insert are plugged in. The above structure can realize the plug-in connection between the ball bodies, and the hexagonal connection can ensure connection stability while having a certain anti-torsion effect.

[0009] In one possible implementation, the riveting component includes a riveting shaft and a riveting cylinder, which are respectively disposed at both ends of the ball body. The outer end of the riveting shaft is machined with a chamfer. When the ball bodies are connected to each other, the riveting shaft and the riveting cylinder are inserted into each other. The above structure can further increase the friction area of ​​the ball body connection, thereby improving the connection strength and significantly enhancing the anti-torsion performance of the connection.

[0010] In one possible implementation, the ball body is composed of two symmetrically arranged frustum structures, which are fixedly connected as one unit by a short shaft. The frustums are arranged with their larger ends facing outwards. This structural form allows grooves for placing materials to be formed between the ball bodies.

[0011] In one possible implementation, the anti-jamming transmission component includes a transmission wheel with a baffle plate fixedly connected to its end. A material drop shaft is fixedly connected to the baffle plate, and the outer end of the material drop shaft has a connecting groove that matches the size of a hexagonal plug. The transmission wheel is meshed with the rotation drive assembly. Based on the above structure, the transmission connection is achieved through the meshing between the transmission wheel and the rotation drive assembly, so that when the ball body moves to the position of the rotation drive assembly, it can rotate under its driving action to flip the material. At the same time, the material drop shaft can separate the transmission wheel from the rotation drive assembly. When dust and debris attached to the surface of the material on the ball body falls off, they will directly contact the material drop shaft and then fall off under the action of gravity, making it difficult to adhere to the rotation drive assembly and the transmission wheel.

[0012] In one possible implementation, the ball bodies are enclosed to form a cross-shaped material clamping groove. A transverse clamping groove is formed between the two frustums constituting the ball bodies, and a vertical clamping groove is formed between adjacent short shafts. The above structure can form clamping grooves in both longitudinal and transverse directions, achieving precise material positioning while also facilitating the screening of materials in multiple directions by the accompanying air blowing screening structure.

[0013] In one possible implementation, the transmission chain mechanism includes a transmission chain with wear-resistant strips on the end face that contacts the drive mechanism. In addition, the inner end face of the transmission chain has mounting holes for mounting a central shaft. When the transmission chain moves, it can drive the ball bearing conveying mechanism mounted on it to move, thereby conveying the material stuck on it.

[0014] In one possible implementation, the drive mechanism includes a plurality of drive gear rollers mounted on a frame and connected to a transmission chain. Some of the drive gear rollers have drive wheels mounted at their ends, which are connected to a drive motor via a chain drive. When the drive motor is working, it can drive the drive gear rollers to rotate, thereby driving the transmission chain mechanism to move.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] The ball conveyor has matching hexagonal connectors and riveting parts at both ends of the ball body. Adjacent ball bodies are fixedly connected by hexagonal connectors and riveting parts. The above structure can provide a stable and reliable connection so that the ball bodies in the same group are tightly connected to each other to form a whole, ensuring that the size of the groove formed between the ball bodies remains unchanged and improving the conveying effect.

[0017] In addition, the end of the ball body is connected to an anti-jamming transmission component, which achieves transmission connection through the meshing between the transmission wheel and the rotation drive component. This allows the ball body to rotate under the driving action of the rotation drive component when it moves to the position of the rotation drive component, turning the material over. At the same time, the discharge shaft can separate the transmission wheel from the rotation drive component. When dust and debris attached to the surface of the material on the ball body fall off, they will directly contact the discharge shaft and then fall off under the action of gravity, making it difficult to adhere to the rotation drive component and the transmission wheel.

Detailed Implementation

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] like Figure 1 - Figure 4 As shown, this embodiment provides a ball-type conveying device, including a frame 1, inside which a transmission chain mechanism 2 is installed. Several sets of ball-type conveying mechanisms 3 arranged in an array are mounted on the transmission chain mechanism 2. A drive mechanism 4 drives the transmission chain mechanism 2 to move. A drive motor 5 drives the drive mechanism 4 to move. A rotation drive assembly 6 drives the contacting ball-type conveying mechanisms 3 to rotate. Each ball-type conveying mechanism 3 includes a central shaft 31, on which several sets of ball bodies 32 are mounted. An anti-jamming transmission component 33, which fits against the ball bodies 32, is installed at the end of the central shaft 31. The two ends of the ball bodies 32 are respectively... The device is equipped with matching hexagonal connectors and riveting parts. Adjacent ball bodies 32 are fixedly connected by hexagonal connectors and riveting parts. The above structure can provide a stable and reliable connection so that the ball bodies 32 in the same group are tightly connected to each other to form a whole. This ensures that the size of the groove formed between the ball bodies 32 remains unchanged, improving the conveying effect. In addition, the anti-jamming transmission component 33 can provide a transition isolation function while realizing the transmission function. It can prevent dust and debris on the material from directly contacting the rotation drive component 6 and the drive mechanism 4 when they fall off, avoiding the situation where the drive structure is jammed and the entire device cannot function.

[0028] The hexagonal connector includes a hexagonal plug 321 and a hexagonal insert 323, which are respectively disposed at both ends of the ball body 32. When the ball bodies 32 are connected to each other, the hexagonal plug 321 and the hexagonal insert 323 are plugged in. This structure enables the plugging connection between the ball bodies 32, and the hexagonal connection can ensure connection stability while providing a certain degree of torsional resistance. The riveting component includes a riveting shaft 322 and a riveting sleeve 324, which are respectively disposed at both ends of the ball body 32. The outer end of the riveting shaft 322 is chamfered. When the ball bodies 32 are connected to each other, the riveting shaft 322 and the riveting sleeve 324 are plugged in. This structure can further increase the friction area of ​​the ball body 32 connection, thereby improving the connection strength and significantly enhancing the torsional resistance of the connection. Figure 4 As shown.

[0029] The ball bearing body 32 is composed of two symmetrically arranged frustum structures, which are fixedly connected as one unit by a short shaft. The frustums are arranged with their larger ends facing outwards. This structural form allows for the formation of material-holding grooves between the ball bearing bodies 32. Specifically, a cross-shaped material-holding groove 301 is formed between the ball bearing bodies 32. A transverse groove is formed between the two frustums constituting the ball bearing body 32, and a vertical groove is formed between adjacent short shafts. This structural form allows for the formation of grooves in both longitudinal and transverse directions, achieving precise material positioning and facilitating the screening of materials in multiple directions by the accompanying air-blowing screening structure. Figure 6 As shown.

[0030] like Figure 5 As shown, the anti-jamming transmission component 33 includes a transmission wheel 331, with a baffle 332 fixedly connected to its end. A material drop shaft 333 is fixedly connected to the baffle 332, and the outer end of the material drop shaft 333 is provided with a connecting groove 334 that matches the size of the hexagonal plug 321. The transmission wheel 331 is meshed with the rotation drive component 6. Based on the above structure, the transmission connection is achieved through the meshing between the transmission wheel 331 and the rotation drive component 6, so that when the ball body 32 moves to the position of the rotation drive component 6, it can rotate under its driving action to flip the material. At the same time, the material drop shaft 333 can separate the transmission wheel 331 from the rotation drive component 6. When the dust and debris attached to the surface of the material on the ball body 32 falls off, it will directly contact the material drop shaft 333 and then fall under the action of gravity, making it difficult to adhere to the rotation drive component 6 and the transmission wheel 331.

[0031] like Figure 3As shown, the transmission chain mechanism 2 includes a transmission chain 21, the end face of which is in contact with the drive mechanism 4 is provided with wear-resistant strips 22. In addition, the inner end face of the transmission chain 21 is provided with mounting holes 23 for mounting the central shaft 31. When the transmission chain 21 moves, it can drive the ball conveying mechanism 3 mounted on it to move, thereby conveying the material stuck on it.

[0032] like Figure 2 As shown, the drive mechanism 4 includes several drive gear rollers 41 mounted on the frame 1, which are connected to the transmission chain 21. Some of the drive gear rollers 41 have drive wheels 42 mounted at their ends, which are connected to the drive motor 5 via chain transmission. When the drive motor 5 is working, it can drive the drive gear rollers 41 to rotate, thereby driving the transmission chain mechanism 2 connected to the transmission chain to move.

[0033] The working principle and usage process of this utility model:

[0034] In use, the drive motor 5 works, which drives the drive gear roller 41 to rotate, thereby driving the transmission chain mechanism 2 to move. When the transmission chain 21 moves, it drives the ball conveying mechanism 3 installed on it to move, thereby conveying the material stuck on it. The transmission connection is achieved through the meshing between the transmission wheel 331 and the rotation drive component 6, so that when the ball body 32 moves to the position of the rotation drive component 6, it can rotate under its driving action to flip the material.

[0035] In this ball conveying device, the two ends of the ball body 32 are respectively provided with matching hexagonal connectors and riveting parts. Adjacent ball bodies 32 are fixedly connected by hexagonal connectors and riveting parts. The above structure can provide a stable and reliable connection so that the ball bodies 32 in the same group are tightly connected to each other to form a whole, ensuring that the size of the groove formed between the ball bodies 32 remains unchanged and improving the conveying effect.

[0036] In addition, the end of the ball body 32 is connected to an anti-jamming transmission component 33, which achieves transmission connection through the meshing between the transmission wheel 331 and the rotation drive component 6. This allows the ball body 32 to rotate under the driving action of the rotation drive component 6 when it moves to the position of the rotation drive component 6, turning the material over. At the same time, the dropping shaft 333 can separate the transmission wheel 331 from the rotation drive component 6. When the dust and debris attached to the surface of the material on the ball body 32 falls off, it will directly contact the dropping shaft 333 and then fall under the action of gravity, making it difficult to adhere to the rotation drive component 6 and the transmission wheel 331.

[0037] 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.
