[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] like Figure 1As shown in Figure 2, this invention provides an intelligent production and transportation line for mining products, including multiple continuous conveyor belts 2. Sorting conveyor belts 1 are symmetrically arranged on both sides of the middle of each conveyor belt 2. A first infrared sensor 3 is fixedly installed below the middle of each conveyor belt 2 via a sensor bracket, and a second infrared sensor 4 is fixedly installed below the lower end of each conveyor belt 2 in the transportation direction via a sensor bracket. The system also includes a controller, which receives signals from the sensors and controls the drive unit to move the conveyor belts. In operation, the required sorting conveyor belt 1 is started, and goods are placed on it. The sorting conveyor belt 1 transports the goods to the conveyor belt 2. The first infrared sensor 3 detects the goods, and the controller controls the drive unit to move the conveyor belt 2. When the goods move to the end of the conveyor belt 2 and enter the next conveyor belt 2, the second infrared sensor 4 detects the goods, starts the drive unit of the next conveyor belt 2, and moves the goods forward; the conveyor belt 2 then stops operating. This configuration allows conveyor belts 2 without goods to be transported to remain stopped, reducing power consumption.

[0028] The controller is also equipped with a delay module. The delay module is used to control the transport conveyor belt 2 to not stop immediately when the second infrared sensor 4 detects the goods. The stopping time is delayed to prevent the goods from being stuck on the transport conveyor belt 2 due to insufficient power when entering the next transport conveyor belt 2.

[0029] like Figure 3As shown in Figure 5, the last conveyor belt 2 in the transport direction of the spacer intelligent production system is the terminal conveyor belt 17, which has a faster transport speed than the previous conveyor belts 2 to ensure that the goods have sufficient power to enter the sealing machine conveyor belt 8. Anti-fall guardrails 5 are fixedly installed on both sides of the terminal conveyor belt 17 to prevent the goods from deviating due to sudden acceleration and falling off the terminal conveyor belt 17. At the end of the terminal conveyor belt 17, a carton sealing machine 6 is connected. The carton sealing machine 6 includes a carton sealing machine conveyor belt 8. A straightening mechanism 12 is installed at the beginning of the carton sealing machine conveyor belt 8, and a tape wrapping mechanism 13 is installed at the center. Straightening frames 16 are also installed on both sides of the carton sealing machine conveyor belt 8. The end face of the straightening frame 16 at the beginning of the carton sealing machine conveyor belt 8 is arc-shaped, which can reduce damage to the goods during the straightening process and act as a buffer. The straightening mechanism 12 includes a slot in the carton sealing machine conveyor belt 8, and a lifting rod 14 is installed inside the slot. The lifting rod 14 can rotate and swing within the slot. When the lifting rod 14 is vertical, it is higher than the plane of the carton sealing machine conveyor belt 8. A roller 15 is also installed on the top of the lifting rod 14. When goods enter the carton sealing machine conveyor belt 8, the goods are lifted by the lifting rod 14, the straightening frames 16 clamp the goods inward to straighten them, and the carton sealing machine 6 wraps the goods with tape. The straightening mechanism 12 can reduce the frictional resistance of the goods to the conveyor belt 8 of the sealing machine during the straightening process, thereby reducing the risk of damage to the goods.

[0030] like Figure 4 As shown, the sealing machine conveyor belt 8 is connected to the palletizer conveyor belt 9 at its end. A third infrared sensor 10 is fixedly installed below the starting position of the palletizer conveyor belt 9 via a sensor bracket, and a fourth infrared sensor 11 is fixedly installed below the ending position via a sensor bracket. A palletizer 7 is installed at the end of the palletizer conveyor belt 9. When the third infrared sensor 10 detects that goods have entered the palletizer conveyor belt 9, the controller controls the drive unit to move the palletizer conveyor belt 9. When the goods have moved to a position where the palletizer 7 can handle them, the palletizer 7 places the goods in the designated position. When the fourth infrared sensor 11 detects that the goods have left the palletizer conveyor belt 9, the controller controls the palletizer conveyor belt 9 to stop running.

[0031] A fifth infrared sensor is also installed on conveyor belt 2. This sensor detects the intersection of conveyor belt 2 and sorting conveyor belt 1. When the fifth infrared sensor detects that goods are being transported at the intersection of conveyor belt 2 and sorting conveyor belt 1, and goods are also being transported from sorting conveyor belt 1 to conveyor belt 2 at the same time, the controller controls sorting conveyor belt 1 to pause transporting goods until the fifth infrared sensor detects that goods on conveyor belt 2 have passed the intersection, at which point sorting conveyor belt 1 restarts. By installing the fifth infrared sensor, the problem of conflicting goods transport at the intersection of sorting conveyor belt 1 and conveyor belt 2 can be resolved.

[0032] like Figure 6 As shown, in another embodiment, the conveyor rollers 18 of the sorting conveyor belt 1 and the transport conveyor belt 2 can also be composed of two variable-diameter conveyor rollers arranged in a mirror image. The two conveyor rollers 18 are hollow cylindrical structures that are thinner in the middle and thicker at both ends. For example... Figure 8 As shown, each conveyor roller 18 consists of two parts: a receiving part and an insertion part. An arc-shaped space is provided in the receiving part, and the insertion part is inserted into the arc-shaped space. Multiple springs 23 are provided at the end of the arc-shaped space, and the two ends of each spring 23 are connected to the end of the arc-shaped space and the top of the insertion part, respectively.

[0033] like Figure 7 As shown, the conveyor roller 18 is internally equipped with a rotating shaft 19, on which a telescopic cylinder 20 is fixedly mounted. The output shaft 21 of the telescopic cylinder 20 is sleeved on the rotating shaft 19, and four external support legs 22 are fixedly connected to the circumference of the output shaft 21. The external support legs 22 are inclined in a direction away from the axis of rotation 19. The inner wall of the conveyor roller 18 is provided with a sliding groove adapted to the moving path of the external support legs 22. The surface of the external support legs 22 in contact with the sliding groove is a smooth arc surface, which reduces the friction of the external support legs 22 on the conveyor roller 18 when sliding inside the sliding groove, thereby reducing wear.

[0034] In use, the telescopic cylinder 20 is activated. When the output shaft 21 of the telescopic cylinder 20 drives the outer support leg 22 to move along the groove on the inner wall of the conveyor roller 18 towards the middle position of the two conveyor rollers 18, the outer support leg 22 opens the conveyor roller 18, and the insertion part slides out from the arc-shaped space of the receiving part, increasing the surface inclination of the conveyor roller 18. When the output shaft 21 of the telescopic cylinder 20 drives the outer support leg 22 to move along the groove on the inner wall of the conveyor roller 18 towards both ends of the two conveyor rollers 18, under the action of the spring 23, the insertion part is pulled back into the arc-shaped space of the receiving part, and the surface inclination of the conveyor roller 18 decreases.

[0035] By setting up conveyor rollers with variable diameters, it is possible to adapt to goods of different fullness, making the goods tend to be horizontal and preventing the products inside from spilling due to tilting; and when transporting larger goods, the transport speed can be increased by increasing the diameter of the conveyor rollers.

[0036] It should be noted that the chute path for the outer support leg 22 to move on the inner wall of the conveyor roller 18 can be set by applying colored paint to the smooth arc surface of the outer support leg 22, activating the telescopic cylinder 20, and moving it from the shortest distance to the longest distance of the output shaft 21. The colored paint will leave a movement path of the outer support leg 22 on the inner wall of the conveyor roller 18, and this movement path is the chute path.

[0037] In actual use, attention should be paid to the length of the insertion part of the conveyor roller 18, that is, when the output device 21 of the telescopic cylinder 20 reaches the longest distance, the spring 23 of the insertion part of the conveyor roller 18 is not exposed from the receiving part.

[0038] The outer wall thickness of the arc-shaped space of the receiving part should be minimized, and the rotation direction of the conveyor roller 18 should be as follows: Figure 8 The clockwise direction shown prevents the outer wall of the curved space of the receiving part from scraping the surface of the goods and causing damage due to the thickness of the outer wall.

[0039] In the description of this invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] However, the above description is merely a specific embodiment of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of the present invention should still fall within the scope of the claims of the present invention.
