Description

Technical Field

[0001] This invention relates to the field of logistics transportation technology, and in particular to a modular belt transport component and NC sorting equipment. Background Technology

[0002] In logistics warehousing, e-commerce delivery, food processing and other fields, efficient transportation and accurate sorting of materials are key to improving production and distribution efficiency. Modular belt transport components are widely used in material conveying scenarios due to their advantages such as stable transportation, strong load-bearing capacity and flexible splicing. Meanwhile, NC (numerical control) sorting equipment has become a key device for material classification due to its high degree of automation and fast sorting speed. Existing NC sorting equipment uses cylinders to push pulleys upwards to lift the module belt, thereby quickly separating materials. However, the partial lifting of the module belt results in a non-horizontal state (see reference). Figure 9 The modular belt, originally a horizontal and parallel conveyor shaft, is now slightly tilted and upturned at one end, thus placing additional loads and increasing the risk of uneven wear on the conveyor shaft. This non-horizontal state disrupts the original uniform force balance between the conveyor shaft and the modular belt, causing the conveyor shaft to shift from bearing normal circumferential uniform friction force to bearing oblique tension and radial uneven load caused by the tilt of the modular belt. The tilted modular belt applies an asymmetrical radial force to the conveyor shaft, resulting in the conveyor shaft being under unilateral force for a long time. This not only easily leads to shaft bending deformation but also changes the fit between the shaft and bearing from coaxial rotation to eccentric friction, accelerating bearing wear and lubrication failure. At the same time, the meshing area between the modular belt and the conveyor shaft will also experience localized stress concentration due to the tilt, thereby affecting the material conveying stability and service life of the entire sorting equipment.

[0003] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0004] This invention provides a modular conveyor assembly and an NC sorting device to solve the problem that the modular conveyor belt of the NC sorting device is partially lifted and becomes non-horizontal, causing the conveyor shaft to be subjected to additional loads and uneven wear, resulting in shaft deformation, bearing wear, and affecting the stability and lifespan of the equipment.

[0005] The present invention adopts the following technical solution: a modular belt transport assembly and an NC sorting device. It mainly includes a conveying assembly comprising two sets of support frames, on which multiple sets of support beams are fixed. A PLC control system is fixed on the support frames near the feeding end. A drive assembly is disposed on the support frames, comprising a drive shaft with bearings disposed between the two sets of support frames for driving the modular belt to rotate. Multiple transmission assemblies are sleeved on the drive shaft, comprising multiple sets of spaced transmission parts fixedly sleeved on the drive shaft, each transmission part having a lifting part. A power part for driving the multiple lifting parts to move synchronously is disposed on the support beams. Multiple NC sorting modules are disposed between the two sets of support frames, and the NC sorting modules are used for sorting goods.

[0006] Furthermore, the transmission unit includes two sets of sprocket rings fixedly sleeved on the drive shaft with a small gap between them. The two sets of sprocket rings are integrally connected by a fixing block, and the sprocket rings are integrally and equidistantly provided with sprocket teeth along the circumferential direction.

[0007] Furthermore, the lifting part includes multiple sets of fixing pins disposed on one side of a set of sprocket rings in the transmission part, near another set of sprocket rings. The multiple sets of fixing pins are equidistantly arranged along the center of the sprocket rings. The number of fixing pins is the same as the number of sprocket teeth. Each set of fixing pins has a movable tooth slidably disposed thereon. The movable tooth has an oblong hole that matches the diameter of the fixing pin. The movable tooth corresponds to the position of the sprocket tooth. One end of the fixing pin is integrally fixed with a step. Initially, the fixing pin is at the top of the oblong hole. Multiple positioning blocks are fixed to the side of the sprocket ring. The number of positioning blocks is the same as the number of movable teeth. The positioning blocks are located on one side of the movable teeth. A driven shaft is movably passed through the side of the positioning block. One end of the driven shaft has a limiting member. A spring is sleeved on the driven shaft. One end of the spring is connected to the limiting member, and the other end is connected to the side of the positioning block. An assembly block is fixed to one end of the driven shaft that protrudes from the positioning block. The assembly block is fixed to the movable teeth.

[0008] Furthermore, the power unit includes a support frame fixed to the bottom surface of multiple sets of support beams. A vertically arranged support rod is fixed on the support frame. A protective box is fixed to the side of the support rod. A linkage shaft is provided in the bearing inside the protective box. A bevel gear three is fixed to one end of the linkage shaft. A movable shaft is provided through the bearing on the side of the protective box. One end of the movable shaft extends into the protective box and is fixed with a bevel gear four that meshes with the bevel gear three. One end of the movable shaft extends out of the protective box and is fixed with a pushing arc block. A spherical end is embedded in the side of the limiting member that contacts the pushing arc block.

[0009] Furthermore, a power motor is fixed to the side of one of the support rods, and a transmission shaft is fixed to the output end of the power motor. The transmission shaft is arranged to pass through multiple sets of support rods. A bevel gear I is fixedly sleeved on the transmission shaft inside multiple sets of support rods. A bevel gear II that meshes with the bevel gear I is fixed to one end of each of the multiple sets of linkage shafts.

[0010] Furthermore, the NC sorting module includes a contact portion disposed between the two sets of support frames. The contact portion includes a mounting plate fixed between the two sets of support frames. Multiple sets of rotating shafts are movably disposed through the mounting plate. One end of each set of rotating shafts is fixed with a mounting bracket of a concave structure. Two sets of pulleys are movably disposed on the mounting bracket. The pulleys are adapted to contact the module belt.

[0011] Furthermore, the rotating part includes a turning rod fixed to the other end of the rotating shaft, and a movable rod is fixed to the eccentric part of the turning rod. The pulleys symmetrically distributed along the center on the mounting plate are divided into a first contact part and a second contact part. The end of the first contact part and the second contact part with the movable rod is connected and fixed to a frame plate to form two sorting units to ensure that the pulleys of the two contact parts move synchronously.

[0012] Furthermore, a waist-shaped plate is fixed to the center surface of the frame plate, and the waist-shaped plate has a movable waist groove adapted to the sliding of the rotating wheel. The mounting plate is supported and fixed to the mounting panel by four pillars, and a gearbox two is fixed to the mounting panel. A drive motor two is fixed to the side of the gearbox two to provide power to the rotating part. The output end of the gearbox two is fixed to the frame plate. Cylinders are also fixed on the two sets of support frames, and the piston rods of the cylinders are connected to the bottom of the mounting plate.

[0013] Furthermore, the PLC control system is electrically connected to the drive motor of the drive assembly, the drive motor of the NC sorting module, the cylinder on the drive mounting plate, and the power motor. Each NC sorting module is equipped with a limit switch, and the feed end of the conveying assembly is equipped with a photoelectric sensor. The PLC control system is connected to the photoelectric sensor signal at the feed end of the equipment.

[0014] Furthermore, this includes the following steps: Step 1: Equipment startup initialization. After the NC sorting equipment is powered on, the drive motor 1 of the drive component is started through the PLC control system, so that the module belt enters the conveyor standby state. At the same time, the cylinder 2 of the top holding component is controlled to reset, ensuring that the top holding part is in the initial low position and does not contact the module belt. Step 2: Material identification and positioning. The photoelectric sensor at the feeding end captures the material signal and transmits it to the PLC. The system determines the target NC sorting module and simultaneously receives the module belt position and spacing data fed back by the limit switch. Step 3: Pre-adjustment of the top support component. The PLC controls the extension and retraction of the cylinder of the top support component according to the limit switch data, and adjusts the support height of the top support component so that the module belt initially reaches the horizontal reference state. Step 4: Lifting Unit Drive. When the material is about to reach the target NC sorting module, the PLC starts the power motor, which drives the arc block to rotate through the transmission shaft, bevel gear 1, bevel gear 2, linkage shaft, bevel gear 3, and bevel gear 4. The moving teeth are driven to push out synchronously from the gap between the two sets of sprocket rings and mesh with the module belt. Step 5: Horizontal coordination and maintenance. The top holding component and the movable tooth work together to achieve the overall horizontal lifting of the module. The PLC monitors the position of the top holding component and the movable tooth in real time through limit switches. If a tilt deviation is detected, the corresponding cylinder or the power motor is finely adjusted. Step Six: Reset and Adjustment. After the material sorting is completed, the PLC controls the power motor to reverse, causing the movable tooth to retract along the fixed pin under the action of the spring. The cylinder of the top holding component is reset, and the module belt returns to the natural conveying state, completing a single cycle.

[0015] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: A modular belt conveyor assembly and NC sorting equipment, by incorporating a lifting section and a power unit on a support beam in the transmission unit, enables multiple sets of movable teeth to simultaneously eject and mesh with the modular belt. Combined with the support of the lifting assembly, this allows the modular belt to be lifted horizontally as a whole, avoiding tilting caused by localized forces. This eliminates the additional oblique tension and radial off-center load on the conveyor shaft due to its non-horizontal state, preventing shaft bending deformation. Simultaneously, the synchronous movement of the lifting section, achieved through gear transmission, ensures uniform meshing between the modular belt and the conveyor shaft, avoiding localized stress concentration, reducing eccentric friction between the shaft and bearings, delaying bearing wear and lubrication failure, and extending the service life of key equipment components. Furthermore, the overall horizontal modular belt conveying state ensures the stability of the material sorting process, reduces the risk of material jamming and slippage caused by tilting, and improves sorting efficiency. Ultimately, structural optimization achieves a dual improvement in equipment operational stability and durability. Attached Figure Description

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1:

[0021] Reference Figures 1-3 As shown in the figure, an embodiment of the present invention provides a module belt transport component and NC sorting equipment, including a conveying component 1, which includes two sets of support frames 11, which are connected and fixed by support legs 111. Multiple sets of support beams 12 are fixed on the support frames 11, and multiple sets of guide plates 13 are fixed on the mutually distant sides of the two sets of support frames 11. The guide plates 13 are inclined downwards and are used to divert the sorted goods to both sides, thereby improving the efficiency and orderliness of goods collection. Furthermore, there are upward-extending baffles 14 near both ends of the guide plates 13, which are used to separate the multiple sets of guide plates 13, thereby preventing goods with different flow directions from interfering with or mixing with each other during the guiding and conveying process, and further ensuring the accuracy and independence of the sorted goods conveying. like Figures 5-6 As shown, a drive assembly 2 is mounted on the support frame 11, serving as the power source for the module's operation. The drive assembly 2 includes a gearbox 22 mounted on the side of the support frame 11. A drive motor 21 is fixed to one end of the gearbox 22, transmitting power to it. A drive shaft 23 is positioned between the two support frames 11 near both ends. Bearings connect both ends of the drive shaft 23 to the two support frames 11, and one end of the drive shaft 23 is connected to the output shaft of the gearbox 22 via a coupling, allowing the drive shaft 23 to rotate freely. The upper sleeve is provided with multiple sets of transmission components 3. The transmission components 3 are used to drive the module belt. The transmission components 3 include multiple sets of transmission parts with spacing fixedly sleeved on the drive shaft 23. The transmission parts include two sets of sprocket rings 31 with spacing fixedly sleeved on the drive shaft 23. There is a small gap between the two sets of sprocket rings 31. The two sets of sprocket rings 31 are integrally connected by a fixing block 321. The sprocket rings 31 are integrally and equidistantly provided with sprocket teeth 32 in the circumferential direction. They are the meshing transmission components of the module belt. Power transmission is realized by meshing with the module belt through the sprocket teeth 32. It should be noted that, in combination Figure 6In actual operation, the sprocket ring 31 is divided into two functional sections by its vertical centerline: the half-circle sprocket ring 31 on the left side of the centerline and its corresponding sprocket teeth 32 are defined as the meshing section. This section is the core area for power transmission with the module belt. The tooth profile of its sprocket teeth 32 is precisely matched with the tooth groove of the module belt, and the module belt can be driven to move synchronously through tight meshing. The half-circle sprocket ring 31 on the right side of the centerline and its corresponding sprocket teeth 32 are defined as the disengagement section. This section is completely separated from the module belt during operation and does not have any contact or meshing. The advantage of this segmented design is that when the drive shaft 23 drives the sprocket ring 31 to rotate, only the meshing section participates in power transmission. The intermittent movement of the module belt can be controlled by periodic meshing and disengagement, which avoids excessive wear of components caused by continuous meshing and can adapt to the start-stop, reversing and other working conditions during material conveying, thereby improving the flexibility and service life of the transmission system.

[0022] In actual operation, when the power source (such as a motor) of the drive component 2 drives the drive shaft 23 to rotate, the sprocket ring 31 rotates synchronously with the drive shaft 23. The meshing section of its sprocket teeth 32 meshes with the module belt, converting the rotational power into the linear motion of the module belt, thereby realizing the conveying of materials. This design, through the segmented meshing characteristics of the sprocket ring 31, can precisely control the engagement and disengagement timing of the module belt, adapt to the conveying requirements under different working conditions, and improve the reliability and flexibility of the module belt drive.

[0023] To address the issue of partial lifting of the NC sorting equipment module in the above embodiments causing non-horizontal movement, resulting in additional load and uneven wear on the conveyor shaft, leading to shaft deformation and bearing wear, and affecting equipment stability and lifespan, as follows: Figures 3-6 As shown, a lifting part is provided on the side of the sprocket ring 31, which is the lifting drive component of the module belt. The lifting part includes multiple sets of fixing pins 33 disposed on the side of one set of sprocket rings 31 in the transmission part near another set of sprocket rings 31. The multiple sets of fixing pins 33 are equidistantly arranged along the center of the sprocket rings 31, and the number of fixing pins 33 is the same as that of sprocket teeth 32. Each set of fixing pins 33 has a movable tooth 34 slidably disposed thereon, which is the lifting execution component of the module belt. It lifts and meshes with the module belt. The mechanism achieves the lifting action. At the same time, the movable tooth 34 is provided with an oblong hole 341 that matches the diameter of the fixed pin 33. This hole serves as a sliding guide for the movable tooth 34, ensuring the linearity of the movable tooth 34 as it slides along the fixed pin 33. The movable tooth 34 corresponds to the sprocket tooth 32. Meanwhile, a step (not shown in the figure) is integrally fixed to one end of the fixed pin 33. This step prevents the movable tooth 34 from slipping off the fixed pin 33. In the initial state, the fixed pin 33 is at the top of the oblong hole 341. Multiple sets of positioning blocks 35 are fixed on the side of the sprocket ring 31. The number of positioning blocks 35 is the same as that of the movable teeth 34. The positioning blocks 35 are located on one side of the movable teeth 34. A driven shaft 36 is movably inserted through the side of the positioning block 35. One end of the driven shaft 36 has a limiting member 37. A spring 38 is sleeved on the driven shaft 36. One end of the spring 38 is connected to the limiting member 37, and the other end is connected to the side of the positioning block 35. At the same time, an assembly block 322 is fixed on the end of the driven shaft 36 that protrudes from the positioning block 35. This assembly block 322 is the connecting component between the driven shaft 36 and the movable teeth 34, ensuring the synchronous movement of the driven shaft 36 and the movable teeth 34. The assembly block 322 is fixed on the movable teeth 34. The number of support beams 12 is the same as that of the transmission units, and a power unit is provided on the support beams 12 to drive the synchronous movement of multiple lifting units. This power unit is the power drive unit for the lifting units, achieving synchronous movement of multiple lifting units through gear transmission. The power unit includes a support frame 39 fixed to the bottom surface of the multiple support beams 12, and a vertically arranged support rod 310 fixed on the support frame 39. A protective box 315 is fixed to the side of the support rod 310. A linkage shaft 316 is mounted on a bearing inside the protective box 315, and a bevel gear 317 is fixed to one end of the linkage shaft 316. Meanwhile, within the protective box 31... A movable shaft 318 is provided on the side of the bearing 5. One end of the movable shaft 318 extends into the protective box 315 and is fixed with a bevel gear 319 that meshes with the bevel gear 317. The other end of the movable shaft 318 extends out of the protective box 315 and is fixed with a pushing arc block 320. At the same time, a spherical end (not shown in the figure) is embedded on the side of the limiting member 37 that contacts the pushing arc block 320. The pushing arc block 320 is adapted to rotate around the axis of the movable shaft 318 to contact the spherical end of a set of limiting members 37, thereby realizing the pushing of the movable tooth 34 out from the gap between the two sets of sprocket rings 31. A power motor 311 is fixed to the side of a set of support rods 310. A transmission shaft 312 is fixed to the output end of the power motor 311. The transmission shaft 312 is arranged to pass through multiple sets of support rods 310. A bevel gear 313 is fixedly sleeved on the transmission shaft 312 inside multiple sets of support rods 310. At the same time, a bevel gear 314 that meshes with the bevel gear 313 is fixed to one end of multiple sets of linkage shafts 316.

[0024] In actual operation, when the module belt needs to be lifted, the power motor 311 starts, and its output torque is synchronously transmitted to multiple sets of bevel gears 313 through the transmission shaft 312. After meshing and reversing with bevel gear 314, it drives multiple sets of linkage shafts 316 to rotate synchronously. Subsequently, bevel gear 317 and bevel gear 319 mesh and reversing again, driving the movable shaft 318 and the push arc block 320 fixed on it to rotate synchronously. Its arc surface evenly pushes each limiting member 37, causing the driven shaft 36 to slide horizontally along the positioning block 35. Through the assembly block 322, it drives all the movable teeth 34 to extend synchronously along the fixing pin 33, and push out evenly from the gap between the two sets of sprocket rings 31 and mesh with the module belt, realizing the overall horizontal lifting of the module belt. After the lifting is completed, the rebound force of the spring 38 pushes the driven shaft 36 to reset, driving the movable teeth 34 to retract synchronously to the initial position. This synchronous action design of multiple sets of movable teeth 34 avoids the tilting of the module belt caused by local lifting through overall horizontal lifting, eliminates the risk of additional load and uneven wear caused by uneven force on the conveyor shaft, reduces the probability of conveyor shaft deformation and bearing wear, effectively ensures the stability of NC sorting equipment operation, and extends the service life of the equipment.

[0025] like Figures 5-6 As shown, multiple NC sorting modules 4 are arranged between two sets of support frames 11 and below the module belt. These multiple NC sorting modules 4 are spaced apart to adapt to the guide plate 13 for sorting and diversion operations. In actual logistics sorting scenarios, different NC sorting modules 4 can correspond to different sorting flows, and the spaced distribution allows goods to be sorted and guided more orderly. Each NC sorting module 4 includes a contact part arranged between the two sets of support frames 11. The contact part includes a mounting plate 41 fixed between the two sets of support frames 11, and multiple sets of rotating shafts 42 are movably arranged through the mounting plate 41. One end of each set of rotating shafts 42 is fixed to a concave structure mounting frame 45, and two sets of pulleys 46 are movably arranged on the mounting frame 45. The pulleys 46 are adapted to contact the module belt. Furthermore, a rotating part is provided at one end of the rotating shaft 42. The rotating part includes a turning rod 43 fixed to the other end of the rotating shaft 42. A movable rod (not shown in the figure) is fixed at the eccentric part of the turning rod 43. Pulleys 46 distributed symmetrically along the center on the mounting plate 41 are divided into a first contact part and a second contact part. The end of the first contact part and the second contact part with the movable rod are both connected to and fixed to a frame plate 44, forming two sorting units and ensuring that the pulleys 46 of the two contact parts move synchronously. A waist-shaped plate 412 is fixed to the center of the frame plate 44. A rotating wheel 411 is movably mounted on the waist-shaped plate 412. The waist-shaped plate 412 has a movable waist groove 413 for the rotating wheel 411 to slide linearly. A mounting panel 48 is supported and fixed on the mounting plate 41 by four pillars 47 (distributed in a rectangular pattern). A gearbox 49 is fixed on the mounting panel 48. A drive motor 410 fixed on the side of the gearbox 49 provides power to the rotating part. The output end of the gearbox 49 is directly fixed to the frame plate 44 to ensure that the power transmission is not delayed. In addition, cylinders (not shown in the figure) are fixed on the two sets of support frames 11. The piston rod of the cylinder is connected to the bottom of the mounting plate 41 and can drive the mounting plate 41 to move upward as a whole, so that the pulley 46 contacts the bottom surface of the module belt. By default, the pulley 46 does not contact the module belt to avoid unnecessary wear on the pulley 46.

[0026] Meanwhile, the equipment uses a PLC control system as its core control unit. This system is fixed to the side of the support frame 11 near the feeding end of the conveyor assembly 1 (not shown in the figure) by an angle steel bracket, and is electrically connected to each key component through shielded wires: on the one hand, it is connected to the drive motor of the drive assembly 2 to control the start, stop and speed of the module belt, connected to the drive motor 410 of the NC sorting module 4 to adjust the deflection direction and angle of the pulley 46, and connected to the cylinder that drives the upward movement of the mounting plate 41 to control the contact or disengagement of the pulley 46 with the module belt (in the default state, the pulley does not contact the module belt to reduce wear), and is also connected to the power motor 311 to drive the lifting part to move; on the other hand, each NC sorting module 4 is equipped with a limit switch to provide real-time feedback to the PLC on the module belt position and horizontal deviation, and the photoelectric sensor set at the feeding end of the conveyor assembly 1 forms a signal connection with the PLC to identify the presence or absence of goods. By integrating these signals and control commands, the PLC can realize the overall control of the equipment from feeding, conveying to sorting, and ensure the coordinated operation of each link.

[0027] Working Principle: After the NC sorting equipment is powered on, the operator issues a running command through the PLC control system at the feeding end of the support frame 11. The system first starts the drive motor 21 of the drive assembly 2. The power is transmitted to the drive shaft 23 through the gearbox 22, which drives the drive shaft 23 between the two sets of support frames 11 (connected at both ends by bearings to ensure flexible rotation) to rotate. The drive shaft 23 synchronously drives multiple sets of transmission assemblies 3, causing the sprocket ring 31 fixed on it to rotate together. The sprocket teeth 32 on its left meshing section precisely mesh with the module belt, converting the rotational power into the linear motion of the module belt. The module belt moves smoothly along the conveying direction and enters the material conveying standby state. At this time, the pulley 46 of the NC sorting module 4 is in the default state, the cylinder is not activated, the mounting plate 41 maintains its initial height, and the pulley 46 does not contact the bottom surface of the module belt to avoid wear when there is no sorting demand. At the same time, the photoelectric sensor at the feeding end is activated to monitor whether the material has entered in real time.

[0028] When material enters the equipment through the feed end, the photoelectric sensor captures the material signal and transmits it to the PLC control system. Based on preset sorting rules (such as target flow direction), the system determines the corresponding NC sorting module 4 (multiple modules are spaced apart to adapt to different guide plates 13 flow paths). Subsequently, the PLC sends a command to the cylinder that drives the module mounting plate 41 upwards. The cylinder piston rod extends, pushing the mounting plate 41, rotating shaft 42, and mounting frame 45 upwards as a whole until the two sets of pulleys 46 on the mounting frame 45 are in close contact with the bottom surface of the module belt, completing the hardware preparation before sorting. During this process, the module belt maintains stable conveying, continuously transporting the material towards the target sorting module.

[0029] As the material approaches the target NC sorting module 4, the PLC simultaneously executes two key operations: First, it starts the power motor 311 of the power unit, which transmits torque to the first bevel gear 313 via the transmission shaft 312. The second bevel gear 314 then reverses direction to drive the linkage shaft 316 to rotate. After a second reversal between the third bevel gear 317 and the fourth bevel gear 319, the movable shaft 318 and the pushing arc block 320 rotate. The arc surface of the pushing arc block 320 pushes the limiting member 37, causing the driven shaft 36 to slide along the positioning block 35. Through the assembly block 322, all the movable teeth 34 extend synchronously along the fixed pin 33, pushing out from the gap between the two sets of sprocket rings 31 and engaging with the module belt, thus achieving the overall horizontal lifting of the module belt. Second, based on the spacing data fed back by the limit switch, it adjusts the support height of the supporting component, cooperating with the movable teeth 34 to ensure the module belt is horizontal. At the same time, the PLC controls the start of the drive motor 410 of the NC sorting module 4, which drives the frame plate 44 to move through the gearbox 49. The rotating shaft 42 is rotated through the turning rod 43, and finally the pulley 46 is deflected to the preset angle (matching the sorting flow direction) to complete the guidance preparation.

[0030] When the material is conveyed by the module belt to the target NC sorting module 4, the module belt remains horizontal with the cooperation of the lifting part and the supporting component, and the pulley 46 has completed its angle adjustment. The pulley 46 transmits deflection force through friction with the bottom surface of the module belt, so that while maintaining straight conveying, the module belt generates directional guiding force along the deflection direction of the pulley 46, causing the material to gradually shift towards the sorting outlet. Finally, the material leaves the main conveying path and slides into the corresponding sorting channel along the inclined guide plate 13 (the baffle 14 separates goods flowing in different directions to avoid mixing). During this process, the sprocket ring 31 of the transmission component 3 continuously drives the module belt through the meshing section and separates from the module belt through the disengagement section, reducing component wear and ensuring stable conveying.

[0031] Once the material has fully entered the sorting channel, the photoelectric sensor sends a "sorting complete" signal to the PLC. The system then sequentially sends reset commands: the drive motor 311 reverses, pushing the arc block 320 to reset; the spring 38 drives the driven shaft 36 and the movable tooth 34 to retract; the movable tooth 34 disengages from the module belt, and the supporting assembly resets synchronously; the cylinder driving the mounting plate 41 retracts, and the pulley 46 separates from the module belt; the drive motor 410 drives the pulley 46 to reset to its initial angle. Subsequently, the module belt continues to run, the photoelectric sensor continuously monitors the feeding end, and the equipment enters the next "feed-sort-reset" cycle. Until a stop command is received, the PLC sequentially shuts down each component, and the equipment stops operating. Example 2:

[0032] In the above embodiment one, to address the problem that the module belt is prone to tilting due to local lifting during the sorting process, the control method to ensure that it always remains in a horizontal state is as follows: S1, Device Startup Initialization NC After the sorting equipment is powered on, the staff issues an operating command through the PLC control system. The system first sends a start signal to the power motor 311 of the drive component, and the drive shaft 23 drives the transmission component to rotate, so that the module belt enters the standby state along the conveying direction, preparing for material conveying. At the same time, the PLC sends a reset command to the cylinder 2 of the top holding component to ensure that the top holding component retracts to the initial low position and does not contact the module belt, so as to avoid interfering with the natural state of the module belt and complete the basic initialization before horizontal control.

[0033] S2, Material Identification and Target Localization When material enters the equipment from the feed end, the photoelectric sensor at the feed end captures the material signal in real time and transmits the signal to the PLC control system in real time. The PLC quickly determines the target NC sorting module corresponding to the material according to the preset sorting rules such as the material destination and type. At the same time, the system synchronously receives data such as the current position of the module belt and the spacing between each segment transmitted by the limit switch. This data will serve as the accurate parameter basis for subsequent horizontal adjustment to ensure that the adjustment action matches the material position.

[0034] S3, Precise pre-adjustment of top component travel Based on the preset spacing data transmitted by the limit switch, the PLC control system sends extension and retraction commands to cylinder two in the corresponding material conveying path in the top holding assembly. By controlling the extension length of the piston rod of cylinder two, the lifting height of the top holding component on the module belt is precisely changed. During the adjustment process, the PLC receives the position signal of the top holding component from the limit switch in real time and continuously corrects the extension and retraction of cylinder two to ensure that the module belt is initially in a horizontal reference state before contacting the lifting part, laying the foundation for subsequent overall lifting.

[0035] S4, Lifting section synchronous drive trigger When the material is about to reach the preset position above the target NC sorting module, the PLC control system sends a start command to the power motor 311 of the power unit. After the power motor 311 starts, the output torque is synchronously transmitted to multiple sets of bevel gears 313 through the transmission shaft 312. After the bevel gears 313 and 314 mesh and reverse direction, multiple sets of linkage shafts 316 are driven to rotate synchronously. The linkage shafts 316 drive the bevel gear 317 in the protective box 315 to rotate. The bevel gear 317 and 319 mesh and reverse direction again, finally driving the movable shaft 318 and the push arc block 320 fixed on it to rotate synchronously, completing the transmission and direction change of the lifting power.

[0036] S5, Synchronous ejection and horizontal engagement When the arc block 320 is rotated, its arc-shaped working surface evenly contacts and pushes the spherical ends of each limiting component 37, causing the movable shaft 318 to slide horizontally along the positioning block 35. The movable shaft 318 drives all the movable teeth 34 to extend synchronously along the movable waist groove 413 of the fixed pin 33 through the assembly block 322, and pushes out evenly from the gap between the two sets of sprocket rings 31, and finally precisely meshes with the tooth groove of the module belt. During this process, the supporting component of the supporting assembly maintains stable support for the module belt, and cooperates with the movable teeth 34 to ensure that the module belt is evenly stressed during the lifting process, realizes overall horizontal lifting, and avoids tilting caused by local stress.

[0037] S6. Real-time monitoring and dynamic correction of horizontal status During the lifting and sorting process of the module belt, the PLC control system continuously monitors the position parameters of the top support and the movable tooth 34 through limit switches, and calculates the horizontal deviation of the module belt in real time. If it is detected that the height of a certain side of the module belt exceeds the preset range, such as local sinking or tilting due to the shift of the material's center of gravity, the system immediately sends a fine-tuning command to the cylinder 2 or the power motor 311 at the corresponding position: the cylinder 2 on the side that needs to be raised extends further to increase the support height, or the push arc block 320 in the corresponding area increases the rotation angle to increase the ejection amount of the movable tooth 34, until the module belt returns to a horizontal state, ensuring that it remains stable throughout the sorting process.

[0038] S7. Reset and adjust after sorting. When the material completely leaves the module belt and enters the sorting channel, the photoelectric sensor sends a "material sorted" signal to the PLC control system. The PLC first sends a reverse rotation command to the power motor 311, which drives the push block 320 to reset through the gear transmission chain. The movable shaft 318 retracts under the rebound force of the spring 38, and the movable tooth 34 slides back to the initial position along the fixed pin 33, disengaging from the module belt. Subsequently, the system sends a reset command to the cylinder of the top holding component, and the top holding component retracts to the initial low position and no longer contacts the module belt. Finally, the module belt returns to the natural conveying state, completing a single horizontal control cycle, and waits for the next material sorting.
