A lead screw 602 is rotatably connected to the opposite side of each set of fourth brackets 601. A set of limiting posts 603 are fixedly inserted into the opposite side of each set of fourth brackets 601. A connecting plate 606 is slidably connected to the outer wall of each limiting post 603. A sliding block 607 is threadedly connected to the outer wall of each lead screw 602. The bottom of the connecting plate 606 and the bottom of the sliding block 607 are fixedly connected. A fifth bracket 604 is fixedly connected to the top of one of the sliding blocks 607. A CCD camera 605 is fixedly connected to the bottom of the fifth bracket 604. A push rod 608 is fixedly connected to the bottom of each sliding block 607. A fixing collar 609 is movably sleeved on the outer surface of each lead screw 602. One end of each component 2 is fixedly connected to the second motor 610. The working platform 1, as the basic support structure of the entire device, provides a platform for the installation and operation of various components, ensuring the overall stability of the device. Its bottom is connected to the width-limiting mechanism 6, providing the positional basis for the width-limiting function. The width-limiting mechanism 6, through two sets installed at the bottom of the working platform 1, is used to adjust the width of the small item transmission path. The fourth bracket 601 serves as the main frame of the width-limiting mechanism 6, providing installation positions for components such as the lead screw 602 and the limiting post 603. The lead screw 602 rotates under the drive of the second motor 610, using a thread to move the sliding block 607. The limiting post 603 provides sliding guidance for the connecting plate 606, ensuring its stability. The sliding block 607 is connected to the connecting plate 606, driving the push rod 608, the fifth bracket 604, and the CCD camera 605 to move synchronously, achieving orderly detection of the number of small items.

[0026] Please see the appendix Figure 1 -Appendix Figure 5 As shown, a first bracket 2 is fixedly connected to the outer surface of the working platform 1, and a first motor 21 is fixedly connected to the top of the first bracket 2. The effects of each segment need to be added, and the effects of the relevant components in this section are discussed. The working platform 1, again emphasizing its role as a basic support, supports the first bracket 2 and the first motor 21 on its top, providing them with a stable mounting foundation. The first bracket 2 connects the working platform 1 and the first motor 21, serving a supporting and positioning function, ensuring that the first motor 21 is in a suitable working position so that it can effectively drive the relevant components. The first motor 21, installed on the top of the first bracket 2, provides a power source for some key moving parts of the equipment. Although its specific driving object is not explicitly stated, it is an important component of the equipment's operating power system.

[0027] Please see the appendix Figure 1 -Appendix Figure 5As shown, a set of second brackets 3 are fixed to the outer surface of the work platform 1. A set of transmission shafts 31 are rotatably connected inside each set of second brackets 3. The effect of each segment needs to be added. The effect of the relevant components in this assembly is to provide a stable mounting surface for the second brackets 3, ensuring the stability of the entire transmission assembly. The second brackets 3 are fixed to the outer surface of the work platform 1 and are rotatably connected to the transmission shafts 31 inside, which plays the role of supporting and positioning the transmission shafts 31, so that the transmission shafts 31 can rotate smoothly, providing a stable power transmission foundation for subsequent transmission actions. The transmission shafts 31 rotate inside the second brackets 3 and transmit power to the pulleys 32 through the connection with the pulleys 32, driving the transmission belt 33 to rotate. It is a key link in the power chain of small item transmission.

[0028] Please see the appendix Figure 1 -Appendix Figure 5 As shown, a set of pulleys 32 are fixedly connected to the outer wall of a set of drive shafts 31. A transmission belt 33 is fixedly connected to the outer wall of each pulley 32. The effect of each segment needs to be added. The effect of the relevant components in this device is discussed. The drive shaft 31, with its outer wall fixedly connected to the pulleys 32, drives the pulleys 32 to rotate synchronously through its own rotation, providing power input to the transmission belt 33. The pulleys 32 are tightly connected to the drive shaft 31, transmitting the rotational motion of the drive shaft 31 to the transmission belt 33. Multiple pulleys 32 work together to ensure the smooth operation of the transmission belt 33, providing a stable carrier for the conveying of small items. The transmission belt 33, wrapped around the outer wall of the pulleys 32, rotates cyclically under the drive of the pulleys 32, carrying small items and conveying them from one position to another. It is a key component for the displacement of small items in the device.

[0029] Please see the appendix Figure 1 -Appendix Figure 5 As shown, a first baffle 4 is fixedly connected to the outer surface of the width limiting mechanism 6, and the opposite sides of the first baffle 4 and the push rod 608 cooperate with each other.

[0030] Please see the appendix Figure 1 -Appendix Figure 5As shown, a feeding baffle 5 is fixedly connected to one end of the first baffle 4. The push rod 608 and the feeding baffle 5 cooperate with each other to add effects as needed. The width limiting mechanism 6, as an integral structure, provides the basic framework for the installation and movement of the first baffle 4 and the push rod 608. The width direction of the small item is controlled by the coordinated adjustment of each component. The first baffle 4 is fixed to the outer surface of the width limiting mechanism 6 and cooperates with the push rod 608 on the opposite side to limit the lateral position of the small item during the transmission process, ensuring that the small item moves within the specified width range. At the same time, it can cooperate with the push rod 608 to arrange the small item or control its movement rhythm. The push rod 608 is connected to the bottom of the sliding block 607 and moves with the sliding block 607. It cooperates with the first baffle 4 to apply a lateral pushing force to the small item, realizing the position adjustment of the small item in the width direction, so as to better perform counting or other operations.

[0031] Please see the appendix Figure 1 -Appendix Figure 5 As shown, a third bracket 34 is fixedly connected to the bottom of the fixed collar 609. Each set of pulleys 32 is rotatably connected to the third bracket 34 via a shaft. The fixed collar 609 is movably sleeved on the outer surface of the lead screw 602, and its bottom is connected to the third bracket 34. It maintains relative stability when the lead screw 602 rotates, providing a fixed support point for the third bracket 34 and indirectly assisting in the installation and stability of the pulleys 32. The third bracket 34, with its bottom connected to the fixed collar 609, provides rotational support for the pulleys 32, enabling them to rotate stably via the shaft and the third bracket 34. This ensures the stability and reliability of the pulleys 32 during the operation of the transmission belt 33, thereby ensuring the smooth operation of the entire transmission system. The pulleys 32, rotatably connected to the third bracket 34 via a shaft, rotate stably under the drive of the transmission shaft 31 with the support of the third bracket 34, efficiently transmitting power to the transmission belt 33 to achieve stable transport of small items.

[0032] Working Principle: Width Limiting Adjustment and Visual Point Preparation Width Limiting Adjustment: The second motor 610 starts, driving the lead screw 602 to rotate. Since the lead screw 602 and the sliding block 607 are threadedly connected, the sliding block 607 will move along the thread direction of the lead screw 602. At the same time, the limiting post 603 is slidably connected to the connecting plate 606, guiding the connecting plate 606 and ensuring its smooth movement. This also causes the sliding block 607 and the connecting plate 606 to move synchronously. Thus, the position of the push rod 608 connected to the bottom of the sliding block 607 changes accordingly, thereby adjusting the width of the small item transmission path to adapt to the transmission needs of small items of different sizes. Visual Point Preparation: The fifth bracket 604 connected to the top of one of the sliding blocks 607 drives the bottom-fixed... The CCD camera 605 moves synchronously. When the width limiting mechanism 6 is adjusted to a suitable width, the CCD camera 605 is also adjusted to a position that can accurately capture small items, preparing for the subsequent visual point counting of small items. Power generation: The first motor 21 starts, providing the main power for the equipment. Although its direct driving object is not explicitly stated, it can be inferred from the overall structure of the equipment that it is likely a key component related to the drive and transmission system. Power transmission: The power generated by the first motor 21 is transmitted to the relevant components on the top of the first bracket 2, which is fixedly connected to the outer surface of the work platform 1, thereby driving the drive shaft 31 to rotate inside the second bracket 3. The pulley 32, which is fixed to the outer wall of the drive shaft 31, rotates synchronously with the drive shaft 31. Small item conveying: The outer wall of the pulley 32 is connected to the pulley 31. The connected conveyor belt 33, driven by the pulley 32, begins to rotate cyclically. Small items are placed on the conveyor belt 33, and as the conveyor belt 33 rotates, the small items are transported along a set path. Width limiting function: The first baffle 4 fixed to the outer surface of the width limiting mechanism 6 cooperates with the push rod 608. The push rod 608 moves under the drive of the sliding block 607, and together with the first baffle 4, it limits the lateral position of the small items on the conveyor belt 33, ensuring that the small items will not shake or deviate from the conveyor path during the transport process, so that the small items are arranged neatly, which is convenient for subsequent counting and unloading operations. Unloading guidance: The unloading baffle 5 fixedly connected to one end of the first baffle 4 works in conjunction with the push rod 608. When the small items are transported by the conveyor belt 33 to a position close to the unloading baffle 5, the unloading guides the unloading. When the small item is in the correct position, the push rod 608 pushes it to contact the discharge baffle 5. The discharge baffle 5 guides the small item away from the conveyor belt 33 and into a specific discharge area or channel. Discharge control: The precise control of the push rod 608 position by the width limiting mechanism 6 can accurately control the timing and position of the small item's discharge, ensuring orderly discharge and avoiding blockages or chaos. Support and stability: The fixed collar 609 is movably sleeved on the outer surface of the lead screw 602. The third bracket 34 connected to its bottom provides rotational support for the pulley 32. The pulley 32 is rotatably connected to the third bracket 34 through a shaft, making the pulley 32 more stable during rotation, thereby ensuring that the conveyor belt 33 can run smoothly and continuously and reliably transport small items.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
