[0025] As Figures 1-4As shown, an adjustable-width synchronous belt conveyor includes a first mounting plate 1 and a second mounting plate 2 arranged parallel to each other, and a synchronous belt conveyor line disposed on the first mounting plate 1 and the second mounting plate 2 for carrying and conveying products. Simultaneously, the first mounting plate 1 and the second mounting plate 2 can move towards or away from each other along a linear motion track via multiple sets of linear guides 3. It should be noted that the conveying direction of the synchronous belt conveyor line is perpendicular to the moving direction of the first mounting plate 1 and the second mounting plate 2. The linear guide 3 includes a guide rail and two sliders slidably connected to the linear guide 3. The bottoms of the first mounting plate 1 and the second mounting plate 2 are respectively connected to the two sliders, and the first mounting plate 1 and the second mounting plate 2 are supported by multiple sets of parallel linear guides 3 to ensure the linear motion accuracy of the first mounting plate 1 and the second mounting plate 2 when moving towards or away from each other. Meanwhile, the first mounting plate 1 and the second mounting plate 2 are respectively threaded to the positive thread and negative thread portion of the positive and negative threaded shaft 4. One end of the positive and negative threaded shaft 4 is connected to the output end of the drive mechanism, and the rotation axis of the positive and negative threaded shaft 4 is parallel to the movement direction of the first mounting plate 1 and the second mounting plate 2. This allows the first mounting plate 1 and the second mounting plate 2 to move synchronously towards or away from each other when the drive mechanism drives the positive and negative threaded shaft 4 to rotate, thereby controlling the spacing between the synchronous belt conveyor line located on the first mounting plate 1 and the synchronous belt conveyor line located on the second mounting plate 2, and meeting the conveying requirements of different product specifications.

[0026] Furthermore, such as Figure 1 , Figure 2 As shown, the drive mechanism in this technical solution includes a servo motor 11, a transmission shaft 12, and synchronous pulleys 13 mounted on the output end of the servo motor 11 and the transmission shaft 12. The transmission shaft 12 and the threaded shaft 4 can be driven together using existing technologies such as couplings. The synchronous pulleys 13 are driven together by a synchronous belt, the structure of which is not shown in the figure. It should be noted that the servo motor 11 is existing technology, and its installation position is relatively fixed, meaning it has no direct connection to the first mounting plate 1 or the second mounting plate 2. Specifically, the servo motor 11 can be mounted on a corresponding motor mounting base, and the transmission shaft 12 can also be rotatably connected to the motor mounting base via bearings, thus forming an independent drive module with the servo motor 11. That is, when the servo motor 11 starts, it can drive the transmission shaft 12 and the threaded shaft 4 to rotate via the synchronous belt and the synchronous pulleys 13. By controlling the rotation direction and angle of the threaded shaft 4, the conveying distance of the conveying device can be flexibly adjusted.

[0027] As described above, the first mounting plate 1 and the second mounting plate 2 are connected to the positive and negative threaded shaft 4 by threaded sleeves, and the two ends of the positive and negative threaded shaft 4 can pass through the first mounting plate 1 and the second mounting plate 2 respectively. The threaded sleeves and the positive and negative threaded shaft 4 are screwed together to form the positive and negative threaded transmission mechanism in the prior art, and its accuracy and stability can be effectively guaranteed.

[0028] It should be noted that, in order to ensure that the function of the synchronous belt conveyor is not affected when adjusting the distance between the first mounting plate 1 and the second mounting plate 2, synchronous belt conveyors in the prior art can be respectively installed on the first mounting plate 1 and the second mounting plate 2, and the synchronous belt conveyors installed on the first mounting plate 1 and the second mounting plate 2 are electrically connected, so that the product can be conveyed through collaborative operation. Example 2

[0029] Unlike the above-mentioned product delivery methods, such as Figure 1 , Figure 2As shown, the synchronous belt conveyor line includes a ball spline assembly 14, driven pulleys 15, driving pulleys 16, tension pulleys 17, and a synchronous conveyor belt 18. Each set of driven pulleys 15, driving pulleys 16, tension pulleys 17, and a synchronous conveyor belt 18 mounted on them forms a single-sided conveying unit. Specifically, the teeth on the driving pulley 16 and several driven pulleys 15 and tension pulleys 17, rotatably connected to the first mounting plate 1 or the second mounting plate 2, mesh with a synchronous conveyor belt 18. The synchronous conveyor belt 18 and these corresponding driven pulleys 15, driving pulleys 16, and tension pulleys 17 form a single-sided conveying unit. Single-sided conveying units are respectively provided on the first mounting plate 1 and the second mounting plate 2. The ball spline assembly 14 can drive the driving pulleys 16 on the first mounting plate 1 and the second mounting plate 2 to rotate synchronously. Specifically, the ball spline assembly 14 is existing technology and mainly consists of a spline shaft, spline sleeve, balls, a circulation device, a sealing device, and a limiting component. In this technical solution, the rotation center axis of the spline shaft coincides with the movement direction of the first mounting plate 1 and the second mounting plate 2. Two spline sleeves are slidably fitted onto the spline shaft. Simultaneously, under the action of the limiting component, the spline sleeves will not detach from the spline shaft. The two spline sleeves are respectively connected to the drive pulley 16 on the first mounting plate 1 and the drive pulley 16 on the second mounting plate 2. The rotation center axis of the spline shaft coincides with the rotation center axis of the two drive pulleys 16. When the spline shaft rotates, torque can be transmitted to the spline sleeves through the rolling friction between the balls and the spline sleeves, causing the spline sleeves and drive pulleys 16 to rotate accordingly, thereby achieving power transmission and ensuring good synchronization of the single-sided conveying units on the first mounting plate 1 and the second mounting plate 2, thus improving the stability of product conveying. Simultaneously, the spline sleeves can move linearly along the axis of the spline shaft, maintaining good rotational performance during linear motion. Rotational and linear motion can be combined to accommodate adjustments in the conveying width.

[0030] As described above, one end of the spline shaft is rotatably connected to the first mounting plate 1 via a bearing, and a driven wheel is sleeved on this end of the spline shaft. A drive motor is mounted on the first mounting plate 1 via a motor frame. The drive motor is existing technology, and a drive wheel is provided at the output end of the drive motor. The rotation center axes of the drive wheel and the driven wheel are parallel to each other, and the drive wheel and the driven wheel are driven by a synchronous belt or chain, so that the two sets of single-sided conveying units can be driven to move synchronously by the drive motor.

[0031] Meanwhile, the first mounting plate 1 and the second mounting plate 2 are respectively provided with product pressing wheels 19 suspended above the synchronous conveyor belt 18. The product pressing wheels 19 are located at the loading position of the conveying device. The product pressing wheels 19 can press down on the surface of the product located on the synchronous conveyor belt 18, and the rotation center axis of the product pressing wheels 19 is perpendicular to the conveying direction of the synchronous conveyor belt 18. That is, the product pressing wheels 19 can rotate with the movement of the product, so that the lower surface of the product is closely attached to the upper surface of the synchronous conveyor belt 18 and relatively stationary, thereby improving the stability of product conveying. Example 3

[0032] like Figure 1 , Figure 3 As shown, based on Embodiment 1, a synchronous belt conveyor device with adjustable width further includes a product lifting mechanism disposed between a first mounting plate 1 and a second mounting plate 2. The product lifting mechanism includes a fixed base 5, a lifting base 6, and a lifting cylinder 7. The bottom of the lifting base 6 is provided with multiple guide shafts 8 that can movably pass through the fixed base 5 to improve the linear motion accuracy of the vertical lifting of the lifting base 6. The output end of the lifting cylinder 7 is connected to the center of the bottom of the lifting base 6, and its output direction is parallel to the guide shafts 8. A lifting plate 9 is detachably connected to the top of the lifting base 6. When the lifting cylinder 7 drives the lifting base 6 to vertically lift upwards, it can lift the product overlapping on the synchronous belt conveyor line, enabling collaborative operation with existing vision inspection modules and robot material handling modules.

[0033] It should be noted that the lifting base 6 and the lifting plate 9 are connected by adjusting screws. The adjusting screws are existing technology and can adjust the distance between the lifting plate 9 and the lifting base 6, thereby fine-tuning the maximum height that the lifting plate 9 can reach to meet the usage requirements.

[0034] In this embodiment, the lifting cylinder 7 is electrically connected to the synchronous belt conveyor to achieve coordinated operation between the synchronous belt conveyor and the lifting cylinder 7. Furthermore, to improve the uniqueness of the product's lifting position by the lifting plate 9, a product stopping module 10 is provided between the first mounting plate 1 and the second mounting plate 2. The product stopping module 10 is existing technology, such as... Figure 4 As shown, the product blocking module 10 consists of an infrared sensor, a cylinder, and a baffle plate located at the output end of the cylinder. The infrared sensor is mounted on the first mounting plate 1 or the second mounting plate 2 and can be electrically connected to the synchronous belt conveyor and the cylinder. Before the product is conveyed to the position directly above the lifting plate 9, the infrared sensor can detect the presence of the product, thereby enabling the cylinder to drive the baffle plate to move in front of the product along the conveying direction to block the product from continuing to be conveyed forward.

[0035] Working principle: The linear guide rail 3 includes a guide rail and two sliders slidably connected to the linear guide rail 3. The bottoms of the first mounting plate 1 and the second mounting plate 2 are respectively connected to the two sliders, and the first mounting plate 1 and the second mounting plate 2 are supported by multiple sets of parallel linear guide rails 3 to ensure the linear motion accuracy of the first mounting plate 1 and the second mounting plate 2 moving towards or away from each other. A positive and negative thread transmission mechanism consisting of a positive and negative threaded shaft 4 and a threaded sleeve is provided between the first mounting plate 1 and the second mounting plate 2. The positive and negative threaded shaft 4 is driven to rotate by a drive mechanism, so that the distance between the first mounting plate 1 and the second mounting plate 2 can be flexibly adjusted, thereby flexibly adjusting the conveying width of the conveying device.

[0036] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
