Description

Technical Field

[0001] This invention relates to the field of logistics sorting, and in particular to a stacked item separation device. Background Technology

[0002] The logistics sorting industry is an indispensable part of the modern logistics system, responsible for the rapid and accurate sorting and delivery of large quantities of items to designated locations. With the rapid development of e-commerce, the logistics industry faces an increasing demand for item sorting.

[0003] Currently, the logistics sorting industry commonly uses stacked item separation equipment to separate and space stacked items so that subsequent automated equipment can accurately identify and sort them. This type of equipment typically consists of multiple conveyor belts with fixed inclination angles, utilizing the slope to separate items and adjust spacing. However, existing stacked item separation equipment usually uses a fixed inclination angle design. For lightweight items, a larger inclination angle is often required for effective separation, but existing equipment, due to its fixed inclination angle, cannot be flexibly adjusted, resulting in poor separation of lightweight items. Conversely, if the inclination angle is increased to accommodate lighter items, heavier items are prone to slipping or having difficulty ascending the slope, affecting overall sorting efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of low separation efficiency and poor adaptability caused by the non-adjustable tilt angle of the conveyor mechanism in existing stacked item separation equipment. This invention provides a stacked item separation device that can adjust the conveyor belt speed and tilt angle of different conveyor mechanisms to achieve the separation of objects of different weights and sizes.

[0005] To address the aforementioned technical problems, embodiments of the present invention disclose a stacked component separation device. The device includes a first conveying mechanism, a second conveying mechanism, and a third conveying mechanism arranged sequentially. The first conveying mechanism includes a first horizontal conveying surface and a first driving assembly, the first driving assembly driving the first horizontal conveying surface to rotate. The second conveying mechanism includes at least one inclined conveying surface, a second driving assembly, and a third driving assembly, the second and third driving assemblies driving the inclined conveying surface to rotate. In the vertical direction, the height of the starting end of the inclined conveying surface is lower than the height of the ending end of the first horizontal conveying surface, and the height of the ending end of the inclined conveying surface is higher than the height of the ending end of the first horizontal conveying surface. The first horizontal conveying surface is used to convey objects to the inclined conveying surface. The third conveying mechanism includes a second horizontal conveying surface and a fourth driving assembly, the fourth driving assembly driving the second horizontal conveying surface to rotate. In the vertical direction, the height of the starting end of the second horizontal conveying surface is lower than or equal to the height of the ending end of the inclined conveying surface. The inclined conveying surface is used to convey objects to the second horizontal conveying surface. The conveying speed of the first horizontal conveying surface is lower than the conveying speed of the inclined conveying surface, and the conveying speed of the inclined conveying surface is lower than or equal to the conveying speed of the second horizontal conveying surface.

[0006] Using the above technical solution, a stacking separation device with a height difference can be constructed. When objects are conveyed from the first horizontal conveying surface to the inclined conveying surface, due to the height difference between the end of the first horizontal conveying surface and the beginning of the inclined conveying surface, this height difference causes the objects to flip or vibrate during the conveying process, causing the stacked objects to fall onto the first horizontal conveying surface or the inclined conveying surface, thereby achieving the separation of the stacked objects. Moreover, the different speeds between the conveying surfaces can also achieve the separation of the stacked objects. For example, the conveying speed of the first horizontal conveying surface is the minimum, the conveying speed of the inclined conveying surface is greater than that of the first horizontal conveying surface, and the conveying speed of the second horizontal conveying surface is greater than or equal to that of the inclined conveying surface. With this configuration, when stacked objects are conveyed between two adjacent conveying surfaces, the lower object first contacts the inclined conveying surface and increases its moving speed. Under the action of inertia, the upper object is thrown out, thereby achieving the separation of the stacked objects. In this way, not only the height difference between the conveying surfaces can be used to achieve the separation of the stacked objects, but also the speed difference can be used to achieve the separation of the stacked objects.

[0007] According to another specific embodiment of the present invention, the first conveying mechanism further includes a first side baffle, which is disposed on both sides of the first conveying mechanism to prevent objects from sliding down from both sides of the first horizontal conveying surface.

[0008] By adopting the above technical solution, the lateral movement of the object can be continuously restricted during the conveying process of the first horizontal conveying surface, preventing the object from leaving the first horizontal conveying surface, thereby keeping the object moving stably along the predetermined path and reducing the conveying interruption or object loss caused by deviation or falling.

[0009] According to another specific embodiment of the present invention, the first conveying mechanism further includes a first brush baffle, a first base frame, and a first frame; in the vertical direction, the first base frame is disposed above the first frame, and the first horizontal conveying surface is disposed above the first base frame; the first frame is provided with a first upright and a second upright for supporting the first base frame disposed on the first frame; the first brush baffle is disposed at the rear end of the first base frame, the first brush baffle includes a first brush plate bracket and a first brush plate, the first brush plate is provided with a first waist hole, the first brush plate bracket is connected to the rear end of the first base frame, the first brush plate is connected to the first brush plate bracket through the first waist hole, the first brush plate slides up and down in the vertical direction through the first waist hole, and the first brush baffle is used to prevent objects from sliding down from the gap between the end of the first horizontal conveying surface and the beginning of the inclined conveying surface.

[0010] By adopting the above technical solution, the first brush plate can be adjusted in the vertical direction through the sliding cooperation between the first waist hole and the first brush plate bracket, thereby sealing the gap formed by the height difference between the end of the first horizontal conveying surface and the beginning of the inclined conveying surface, and preventing the object from slipping or getting stuck at the mechanism connection.

[0011] According to another specific embodiment of the present invention, the first driving assembly includes a first conveyor belt, a first driving roller, a first driven roller, a first driving motor, and a first support side plate and a second support side plate disposed on both sides of a first horizontal conveying surface; the conveying surface of the first conveyor belt is a first horizontal conveying surface; in the vertical direction, the first support side plate and the second support side plate are located below the first side baffle; the first driving roller is disposed at the end of the first horizontal conveying surface, and the first driven roller is disposed at the beginning of the first horizontal conveying surface, for conveying objects on the first horizontal surface to the inclined conveying surface; the first driving motor is disposed between the first support side plate and the second support side plate, the first driving motor is connected to the first support side plate through a first driving motor mounting seat disposed on the first support side plate, the first driving motor drive shaft is connected to a first synchronous pulley, the first synchronous pulley is connected to a second synchronous pulley through a first synchronous belt, and the second synchronous pulley is connected to the drive shaft of the first driving roller, for driving the first driving roller and the first driven roller to rotate, so as to realize the rotation of the first conveyor belt.

[0012] Using the above technical solution, the first support side plate and the second support side plate set on both sides of the first horizontal conveying surface provide installation support and positioning for the first active roller, the first driven roller and the first drive motor; at the same time, by driving the first conveyor belt to rotate through the first drive motor, the object placed on it can be conveyed from the starting end to the end end, and further transferred to the inclined conveying surface.

[0013] According to another specific embodiment of the present invention, the second conveying mechanism further includes a second side baffle, which is disposed on both sides of the second conveying mechanism to prevent objects from sliding off the sides of the inclined conveying surface.

[0014] By adopting the above technical solution, the lateral movement of objects can be continuously restricted during the conveying process on the inclined conveying surface, preventing objects from leaving the inclined conveying surface, thereby keeping objects moving stably along the predetermined path and reducing conveying interruptions or object losses caused by deviation or falling.

[0015] According to another specific embodiment of the present invention, the second conveying mechanism further includes a second brush baffle, a second base frame, and a second frame; in the vertical direction, the second base frame is disposed above the second frame, and the inclined conveying surface is disposed above the second base frame; the second brush baffle is disposed at the rear end of the second base frame, the second brush baffle includes a second brush plate bracket and a second brush plate, the second brush plate is provided with a second waist hole, the second brush plate bracket is connected to the rear end of the second base frame, the second brush plate is connected to the second brush plate bracket through the second waist hole, the second brush plate slides up and down in the vertical direction through the second waist hole, and the second brush baffle is used to prevent objects from sliding down from the gap between the end of the inclined conveying surface and the beginning of the second horizontal conveying surface.

[0016] By adopting the above technical solution, the second brush plate can be adjusted in the vertical direction through the sliding cooperation between the second waist hole and the second brush plate bracket, thereby sealing the gap formed by the height difference between the end of the inclined conveying surface and the beginning of the second horizontal conveying surface, and preventing the object from slipping or getting stuck at the mechanism connection.

[0017] According to another specific embodiment of the present invention, the second frame is provided with a third upright at the front end of the second base frame, and the second frame is provided with a fourth upright at the rear end of the second base frame. The height of the third upright is lower than the height of the fourth upright. The third upright is provided with a first rotating connector, and the fourth upright is provided with a first lifting assembly. The first lifting assembly is used to lift the rear end of the second base frame. The second base frame rotates around the first rotating connector as a fulcrum to realize the synchronous change of the inclination angle of the inclined conveying surface.

[0018] By adopting the above technical solution, a fulcrum for rotation is provided by a rotating connector on the lower third upright, and the rear end of the second base frame is raised or lowered by a first lifting component on the higher fourth upright. This allows the second base frame to rotate around the first rotating connector as a fulcrum, thereby directly changing the inclination angle of the inclined conveyor surface. At the same time, by adjusting the first lifting component, the angle of the inclined conveyor surface can be made smaller to facilitate the stable climbing of heavy objects overcoming friction; or the angle of the inclined conveyor surface can be made larger to facilitate the more effective separation of stacked lightweight objects.

[0019] According to another specific embodiment of the present invention, the first rotating connector includes a first hinge seat, a first pin, a first mounting seat, and a first rubber pad. The first hinge seat is disposed on the third upright and has a first hinge seat pin hole. The first mounting seat is disposed on the first rubber pad and has a first mounting hole. The first pin is inserted into the first hinge seat pin hole and the first mounting hole. The first rubber pad is disposed below the front end of the second base frame in the vertical direction.

[0020] By adopting the above technical solution, the first hinge seat on the third upright and the first mounting seat on the first rubber pad are connected by inserting the first pin into the first hinge seat pin hole and the first mounting hole, thereby forming a rotatable fulcrum below the front end of the second base frame. This structure allows the second base frame to rotate with the pin as the fulcrum, while the first rubber pad can buffer the vibration and impact generated during the rotation.

[0021] According to another specific embodiment of the present invention, the first lifting assembly includes a first fisheye screw, a first pin, and a second rubber pad. The first fisheye screw includes a first fisheye screw pin hole and a first fisheye screw threaded rod. The first fisheye screw threaded rod is connected to the fourth upright. The first pin is inserted into the first fisheye screw pin hole. Both ends of the first pin are connected to the second rubber pad. The second rubber pad is disposed below the rear end of the second base frame in the vertical direction.

[0022] By adopting the above technical solution, the first fisheye screw is rotated so that the threaded rod of the first fisheye screw is screwed in or out of the fourth upright, thereby changing the extension length of the first fisheye screw from the fourth upright, thereby lifting or lowering the rear end of the second base frame set above the fourth upright; at the same time, the first pin inserted into the pin hole of the first fisheye screw transmits the lifting force to the second rubber pad, so that the second rubber pad always keeps in contact with the bottom surface of the second base frame, buffering local contact stress.

[0023] According to another specific embodiment of the present invention, the angle range of the inclined conveying surface rotation is 18°-25°, wherein when the transported object has a mass greater than 1.5kg, the rotation angle of the inclined conveying surface is 18°-20°, and when the transported object has a mass less than or equal to 1.5kg, the rotation angle of the inclined conveying surface is 22°-25°.

[0024] By adopting the above technical solution, the rotation angle of the inclined conveyor surface is set to different ranges according to the mass of the object: for objects with larger mass, a smaller inclination angle of 18°-20° is used to provide sufficient traction force to overcome friction and move upward stably; for objects with smaller mass, a larger inclination angle of 22°-25° is used to facilitate more effective separation of stacked lightweight objects.

[0025] According to another specific embodiment of the present invention, the second drive assembly includes a second conveyor belt, a second drive roller, a second driven roller, a second drive motor, and a third support side plate and a fourth support side plate disposed on both sides of the inclined conveying surface; in the vertical direction, the third support side plate and the fourth support side plate are located below the second side baffle, and the third support side plate and the fourth support side plate are disposed on both sides of the second conveyor belt; in the direction of conveying the object, the second drive roller is disposed at the end of the second conveyor belt, and the second driven roller is disposed at the beginning of the second conveyor belt; the second drive motor is disposed between the third support side plate and the fourth support side plate, the second drive motor is connected to the third support side plate through a second drive motor mounting seat disposed on the third support side plate, the second drive motor drive shaft is connected to a third synchronous pulley, the third synchronous pulley is connected to the fourth synchronous pulley through a second synchronous belt, and the fourth synchronous pulley is connected to the drive shaft of the second drive roller, for driving the second drive roller and the second driven roller to rotate, thereby driving the rotation of the second conveyor belt.

[0026] Using the above technical solution, the third and fourth support side plates located on both sides of the second conveyor belt provide mounting support and positioning for the second driving roller, the second driven roller, and the second drive motor. Simultaneously, the second drive motor drives the second conveyor belt to move, providing power for conveying objects on the inclined conveying surface.

[0027] According to another specific embodiment of the present invention, the third drive assembly further includes a third conveyor belt, a third driving roller, a third driven roller, a third drive motor, and a fifth support side plate and a sixth support side plate disposed on both sides of the inclined conveying surface; along the direction of conveying the object, the second conveyor belt and the third conveyor belt are arranged sequentially, the conveying surface of the second conveyor belt and the third conveyor belt is an inclined conveying surface, and the second conveyor belt and the third conveyor belt are used to convey the object on the inclined conveying surface to the second horizontal conveying surface; along the vertical direction, the fifth support side plate and the sixth support side plate are located below the second side baffle, and the fifth support side plate and the sixth support side plate are disposed on both sides of the third conveyor belt; along the direction of conveying the object... The third driving roller is located at the starting end of the third conveyor belt, and the third driven roller is located at the end of the third conveyor belt. The starting end of the third conveyor belt is adjacent to the end of the second conveyor belt. The third drive motor is located between the fifth support side plate and the sixth support side plate. The third drive motor is connected to the fifth support side plate through a third drive motor mounting base located on the fifth support side plate. The third drive motor is connected to the fifth synchronous pulley. The fifth synchronous pulley is connected to the sixth synchronous pulley through the third synchronous belt. The sixth synchronous pulley is connected to the drive shaft of the third driving roller. The third driving roller and the third driven roller are used to drive the third driving roller and the third driven roller to rotate, thereby driving the rotation of the third conveyor belt.

[0028] By adopting the above technical solution, a third conveyor belt and its matching drive components are installed behind the second conveyor belt along the direction of the conveyed objects, extending the overall working length of the inclined conveyor surface. The third drive motor transmits power to the third drive roller through the fifth synchronous pulley, the third synchronous belt, and the sixth synchronous pulley, driving the third conveyor belt to rotate. The second and third conveyor belts work together, allowing the objects to experience a longer acceleration and separation zone during the climbing process, providing more opportunities for stacked objects to slide off and space out. The fifth and sixth support side plates located on both sides of the third conveyor belt provide mounting support and positioning for the third drive roller, the third driven roller, and the third drive motor. Simultaneously, by driving the second and third conveyor belts to rotate, respectively, the objects placed on the inclined conveyor surface can be conveyed from the starting end to the end, and further transferred to the second horizontal conveyor surface.

[0029] According to another specific embodiment of the present invention, the third conveying mechanism further includes a third side baffle, which is disposed on both sides of the third conveying mechanism to prevent objects from sliding down from both sides of the second horizontal conveying surface.

[0030] By adopting the above technical solution, the lateral movement of the object can be continuously restricted during the conveying process on the second horizontal conveying surface, preventing the object from leaving the second horizontal conveying surface, thereby keeping the object moving stably along the predetermined path and reducing conveying interruptions or object losses caused by deviation or falling.

[0031] According to another specific embodiment of the present invention, the fourth drive assembly includes a fourth conveyor belt, a fourth driving roller, a fourth driven roller, a fourth drive motor, and a seventh support side plate and an eighth support side plate disposed on both sides of the inclined conveying surface; the conveying surface of the fourth conveyor belt is a second horizontal conveying surface; in the vertical direction, the seventh support side plate and the eighth support side plate are located below the third side baffle; the fourth driving roller is disposed at the end of the second horizontal conveying surface, and the fourth driven roller is disposed at the beginning of the second horizontal conveying surface, for conveying objects on the second horizontal conveying surface; the fourth drive motor is disposed between the seventh support side plate and the eighth support side plate, the fourth drive motor is connected to the seventh support side plate through a fourth drive motor mounting seat disposed on the seventh support side plate, the fourth drive motor drive shaft is connected to the seventh synchronous pulley, the seventh synchronous pulley is connected to the eighth synchronous pulley through the fourth synchronous belt, and the eighth synchronous pulley is connected to the drive shaft of the fourth driving roller, for driving the fourth driving roller and the fourth driven roller to rotate, thereby realizing the rotation of the fourth conveyor belt.

[0032] Using the above technical solution, the seventh and eighth support side plates set on both sides of the second horizontal conveying surface provide installation support and positioning for the fourth driving roller, the fourth driven roller and the fourth drive motor; at the same time, the fourth drive motor drives the fourth conveyor belt to rotate, which can transport the objects placed on it from the starting end to the end.

[0070] refer to Figures 1A to 1B This application provides a stacking separation device 1, comprising a first conveying mechanism 10, a second conveying mechanism 20, and a third conveying mechanism 30 arranged sequentially. The first conveying mechanism 10 includes a first horizontal conveying surface 100 and a first driving assembly 102, which drives the first horizontal conveying surface 100 to rotate. The second conveying mechanism 20 includes at least one inclined conveying surface 200, a second driving assembly 202, and a third driving assembly 203, which drive the inclined conveying surface 200 to rotate. Vertically, the height of the starting end of the inclined conveying surface 200 is lower than the height of the ending end of the first horizontal conveying surface 100, and the height of the ending end of the inclined conveying surface 200 is higher than the height of the ending end of the first horizontal conveying surface 100. The first horizontal conveying surface 100 is used to convey objects to the inclined conveying surface 200. The third conveying mechanism 30 includes a second horizontal conveying surface 300 and a fourth driving assembly 302, which drives the second horizontal conveying surface 300 to rotate. In the vertical direction, the height of the starting end of the second horizontal conveying surface 300 is lower than or equal to the height of the ending end of the inclined conveying surface 200. The inclined conveying surface 200 is used to convey objects to the second horizontal conveying surface 300. The conveying speed of the first horizontal conveying surface 100 is less than the conveying speed of the inclined conveying surface 200, and the conveying speed of the inclined conveying surface 200 is less than or equal to the conveying speed of the second horizontal conveying surface 300.

[0071] refer to Figure 1A , Figure 1B and Figure 1C This application mainly combines the first conveying mechanism 10, the second conveying mechanism 20, and the third conveying mechanism 30 to construct a stacked component separation device with a height difference. Among them, such as... Figure 1CAs shown, three stacked objects are conveyed onto the first horizontal conveying surface 100 of the first conveying mechanism 10. The first drive motor 10203 drives the first active roller 10201 to rotate, which, together with the first driven roller 10202, drives the first conveyor belt 10200. The conveying surface of the rotating first conveyor belt 10200 is the first horizontal conveying surface 100. The objects are then conveyed to the inclined conveying surface 200 of the second conveying mechanism 20. The second drive motor 20203 and the third drive motor 20303 drive the second active roller 20201 and the third active roller 20301 to rotate, which, together with the second driven roller 20202 and the third driven roller 20302, drive the second conveyor belt 20200 and the third conveyor belt 20300 arranged sequentially. The conveying surfaces of the rotating second conveyor belt 20200 and the third conveyor belt 20300 together form the inclined conveying surface 200. Because of the height difference between the end of the first horizontal conveying surface 100 and the beginning of the inclined conveying surface 200, the upper objects will flip or vibrate during the conveying process to the inclined conveying surface 200, causing them to fall onto the first horizontal conveying surface 100 or the inclined conveying surface 200, thus achieving initial vertical separation of the stacked objects. Then, after passing through multiple inclined conveying surfaces 200, the distance between the stacked objects gradually increases, achieving spacing separation in the conveying direction. Finally, the separated objects are conveyed from the inclined conveying surface 200 to the second horizontal conveying surface 300 of the third conveying mechanism 30. The fourth drive motor 30203 drives the fourth active roller 30201 to rotate, which, together with the fourth driven roller 30202, drives the fourth conveyor belt 30200. The conveying surface of the rotating fourth conveyor belt 30200 is the second horizontal conveying surface 300. The second horizontal conveying surface 300 then delivers the three separated objects, achieving the final sorting of the objects. Of course, different speeds between the conveyor surfaces can also achieve the separation of stacked items. For example, the first drive motor 10203 drives the first conveyor belt 10200, causing the first horizontal conveyor surface 100 to operate at a conveying speed V1 of 1 m / s, serving to collect items and provide buffering. The second drive motor 20203 and the third drive motor 20303 respectively drive the second conveyor belt 20200 and the third conveyor belt 20300, causing the conveying speed V2 of the inclined conveyor surface 200 to be 2 m / s, which is greater than the conveying speed of the first horizontal conveyor surface 100. When stacked objects are conveyed from the first horizontal conveyor surface 100 to the inclined conveyor surface 200, the lower objects first come into contact with the high-speed inclined conveyor surface 200 and accelerate forward, while the upper objects lag behind due to inertia, thus separating from the lower objects under the action of the acceleration difference; further, the fourth drive motor 30203 drives the fourth conveyor belt 30200 to operate, so that the conveying speed V3 of the second horizontal conveyor surface 300 is 2.5m / s, which is greater than the speed of the inclined conveyor surface 200, so that the separated objects continue to be conveyed and the spacing is increased, thereby realizing the separation of stacked objects.In this way, not only can the height difference between the conveying surfaces be used to separate the stacked parts, but the speed difference between the conveying mechanisms can also be used to separate the stacked parts.

[0072] It should be noted that the number of inclined conveying surfaces 200 and second driving components 202 in the second conveying mechanism can be selected as needed. In this embodiment, the second conveying mechanism includes four sequentially arranged inclined conveying surfaces 200 and second driving components 202 with gradually increasing heights. This arrangement extends the overall separation stroke of the objects, requiring them to undergo multiple continuous climbs and accelerations during the conveying process. This provides more opportunities for stacked objects to slide and widen the gaps, improving the separation effect of the stacked objects. Of course, in other embodiments, the number of inclined conveying surfaces 200 and second driving components 202 can also be one, two, three, etc., and is not specifically limited here.

[0073] In some possible implementations, the first conveying mechanism 10 further includes a first side baffle 101, which is disposed on both sides of the first conveying mechanism 10. This arrangement continuously restricts the lateral movement of the object during the conveying process on the first horizontal conveying surface 100, preventing the object from leaving the first horizontal conveying surface 100, thereby keeping the object moving stably along the predetermined path and reducing conveying interruptions or object losses caused by deviation or falling.

[0074] Exemplarily, the first side baffle 101 of this application includes a first guard plate 106. The first guard plate 106 is disposed at the rear end of the first side baffle 101, and is used to prevent objects from getting stuck or falling into the gap between the first side baffle 101 and the second side baffle 201, thus preventing damage to the objects and the conveying mechanism. In some possible embodiments, the first conveying mechanism 10 further includes a first brush baffle 103, a first base frame 104, and a first frame 105. (See reference...) Figure 3A and Figure 3B Vertically, a first base frame 104 is positioned above a first frame 105, and a first horizontal conveying surface 100 is positioned above the first base frame 104. The first frame 105 is provided with a first upright 1050 and a second upright 1051 to support the first base frame 104 mounted on the first frame 105. (Reference) Figure 2A and Figure 3AA first gap 107 exists between the first drive assembly 102 and the second drive assembly 202. A first brush baffle 103 is disposed at the rear end of the first base frame 104. The first brush baffle 103 includes a first brush plate bracket 1030 and a first brush plate 1031. The first brush plate 1031 has a first waist hole 1032. The first brush plate bracket 1030 is connected to the rear end of the first base frame 104, and the first brush plate 1031 is connected to the first brush plate bracket 1030 through the first waist hole 1032. The first brush plate 1031 slides vertically up and down through the first waist hole 1032. This configuration allows the first brush plate 1031 to be adjusted vertically through the sliding engagement of the first waist hole 1032 and the first brush plate bracket 1030. This adjusts the brush height of the first brush baffle 103, thereby sealing the first gap 107 formed by the height difference between the end of the first horizontal conveying surface 100 and the beginning of the inclined conveying surface 200, preventing objects from slipping or getting stuck at the mechanism connection.

[0075] refer to Figure 4A , Figure 4B and Figure 5 The first drive assembly 102 of this application includes a first conveyor belt 10200, a first drive roller 10201, a first driven roller 10202, a first drive motor 10203, and a first support side plate 10205 and a second support side plate 10206 disposed on both sides of a first horizontal conveying surface 100. The conveying surface of the first conveyor belt 10200 is the first horizontal conveying surface 100. In the vertical direction... Figure 4A and Figure 4BThe diagram shows that the first support side plate 10205 and the second support side plate 10206 are located below the first side baffle 101. The first driving roller 10201 is located at the end of the first horizontal conveying surface 100, and the first driven roller 10202 is located at the beginning of the first horizontal conveying surface 100, for conveying objects on the first horizontal conveying surface 100 to the inclined conveying surface 200. The first drive motor 10203 of this application is disposed between the first support side plate 10205 and the second support side plate 10206. The first drive motor 10203 is connected to the first support side plate 10205 through the first drive motor mounting seat 10204. The first drive motor transmission shaft 102030 is connected to the first synchronous pulley 10207. The first synchronous pulley 10207 is connected to the second synchronous pulley 10208 through the first synchronous belt 10209. The second synchronous pulley 10208 is connected to the first drive roller transmission shaft 102010, and is used to drive the first drive roller 10201 and the first driven roller 10202 to rotate. When the first drive motor drive shaft 102030 rotates, it drives the first synchronous pulley 10207 connected to it to rotate. The first synchronous pulley 10207 transmits the rotational motion to the second synchronous pulley 10208 through the first synchronous belt 10209. The second synchronous pulley 10208 drives the first drive roller drive shaft 102010 to rotate, thereby driving the first drive roller 10201 to rotate. Through the friction between the first conveyor belt 10200 and the roller, the first driven roller 10202 rotates accordingly. Finally, the first conveyor belt 10200 moves horizontally under the drive of the first drive roller 10201 and the first driven roller 10202, conveying the object placed on the first horizontal conveying surface 100 from the starting end to the end end, and transferring it to the inclined conveying surface 200. With this configuration, the first support side plate 10205 and the second support side plate 10206 of the first horizontal conveying surface 100 provide mounting support and positioning for the first driving roller 10201, the first driven roller 10202 and the first drive motor 10203; at the same time, the first drive motor 10203 drives the first conveyor belt 10200 to rotate, which can transport the objects placed on it from the starting end to the end, and further transfer them to the inclined conveying surface 200, ensuring the smooth operation of the objects during the conveying process.

[0076] In some possible implementations, the first drive assembly 102 further includes a first roller adjustment assembly 10218 and a first guide wheel adjustment assembly 10221. The first roller adjustment assembly 10218 is disposed on the left and / or right side of the first roller mounting hole 10220 in the first support side plate 10205 and the second support side plate 10206 for accommodating the first driven roller drive shaft 102020. A first roller baffle 10219 is disposed on the left and / or right side of the first mounting hole to prevent the first driven roller drive shaft 102020 from dislodging from its mounting position during adjustment or operation. The first roller adjustment assembly 10218 includes a first nut plate 102180 and a first adjusting rod 102181 inserted into the first nut plate 102180. By rotating the first adjusting rod 102181, the axial position of the first driven roller drive shaft 102020 in the first roller mounting hole 10220 can be pushed, thereby adjusting the relative distance between the first driving roller 10201 and the first driven roller 10202, so as to adjust the tension of the first driving roller 10201, the first driven roller 10202 and the end of the first conveyor belt 10200. The first guide wheel adjustment assembly 10221 is disposed below the first roller adjustment assembly 10218 in the vertical direction. The first guide wheel adjustment assembly 10221 includes a first guide wheel mounting base 102212, a first guide wheel adjustment plate 102211, and a first guide wheel 102210 placed on the first guide wheel adjustment plate 102211. The first guide wheel adjustment plate 102211 is disposed above the first guide wheel mounting base 102212 in the vertical direction, and the first guide wheel 102210 is disposed on the first guide wheel adjustment plate 102211. The first guide wheel 102210 corrects the running trajectory of the first conveyor belt 10200 by contacting the side edge of the first conveyor belt 10200, preventing the first conveyor belt 10200 from deviating to one side and ensuring that the first conveyor belt 10200 runs smoothly and centrally.

[0077] Furthermore, the first drive component 102 of this application also includes a first protective cover 10214, a second protective cover 10215, a third protective cover 10216, and a fourth protective cover 10217. (Continued reference) Figure 4A and Figure 4BThe first protective cover 10214 and the second protective cover 10215 are disposed on the first support side plate 10205 and connected to the first support side plate 10205 through the first protective cover bracket 10210 and the second protective cover bracket 10211; the third protective cover 10216 and the fourth protective cover 10217 are disposed on the second support side plate 10206 and connected to the second support side plate 10206 through the third protective cover bracket 10212 and the fourth protective cover bracket 10213. This arrangement can prevent external foreign objects from entering the first drive assembly 102 and prevent personnel limbs from coming into contact with the moving first conveyor belt 10200, the first drive roller 10201, the first driven roller 10202, and the first synchronous belt 10209.

[0078] In some possible implementations, the second conveying mechanism 20 further includes a second side baffle 201, which is disposed on both sides of the first conveying mechanism 10. This arrangement continuously restricts the lateral movement of the object during the conveying process on the inclined conveying surface 200, preventing the object from leaving the inclined conveying surface 200, thereby keeping the object moving stably along the predetermined path and reducing conveying interruptions or object losses caused by deviation or falling.

[0079] By way of example, the second side baffle 201 of this application includes a second guard plate 209. (See reference...) Figure 1A and Figure 1B The second guard plate 209 is disposed at the rear end of the second side baffle 201. The second guard plate 209 is used to prevent objects from getting stuck or falling from the gaps between the second side baffles 201 and / or with the third side baffle 301, so as to prevent damage to the objects and the conveying mechanism.

[0080] It should be noted that the combination of the second side baffle 201 and the second guard plate 209 in this application causes the second side baffles 201 to stack on each other to form a fish scale-like structure. This structure can cover the gaps that increase or change due to the change in angle of the inclined conveying surface 200 by the relative displacement between the second side baffles 201 when the angle changes, thus preventing objects from entering or getting stuck in the gaps.

[0081] In some possible implementations, the second conveying mechanism further includes a second brush baffle 204, a second base frame 205, and a second frame 206. (See reference) Figure 2B , Figure 6A and Figure 6B Vertically, the second base frame 205 is positioned above the second frame 206, and the inclined conveying surface 200 is positioned above the second base frame 205. (Reference) Figure 2B and Figure 6BA second gap 210 exists between the second drive assembly 202 and the third drive assembly 203. A second brush baffle is disposed at the rear end of the second base frame 205. The second brush baffle includes a second brush plate bracket 2040 and a second brush plate 2041. The second brush plate 2041 has a second waist hole 2042. The second brush plate bracket 2040 is connected to the rear end of the second base frame 205, and the second brush plate 2041 is connected to the second brush plate bracket 2040 through the second waist hole 2042. The second brush plate 2041 slides vertically up and down through the second waist hole 2042. This configuration, through the sliding engagement of the second waist hole 2042 and the second brush plate bracket 2040, allows the second brush plate 2041 to be adjusted in the vertical direction, thereby adjusting the brush height of the second brush baffle 204. This seals the gap formed by the height difference between the starting and ending ends of the inclined conveying surface 200, or the second gap 210 formed by the height difference between the ending end of the inclined conveying surface 200 and the starting end of the second horizontal conveying surface 300, preventing objects from slipping or getting stuck at the mechanism connection.

[0082] refer to Figures 6A to 6C The second frame 206 of this application is provided with a third upright 2060 located at the front end of the second base frame 205, and a fourth upright 2061 located at the rear end of the second base frame 205. The height of the third upright 2060 is lower than the height of the fourth upright 2061. The third upright 2060 is provided with a first rotating connector 207, and the fourth upright 2061 is provided with a first lifting assembly 208. The first lifting assembly 208 is used to lift the rear end of the second base frame 205. When the first lifting assembly 208 is operated, it raises or lowers the rear end of the second base frame 205, causing the second base frame 205 to rotate around the first rotating connector 207 as a fulcrum, thereby directly changing the inclination angle of the inclined conveying surface 200 provided on the second base frame 205. This setup allows for adjustments to the first lifting component 208, which can create a smaller angle on the inclined conveyor surface 200 to facilitate the stable climbing of heavy objects by overcoming friction; or a larger angle on the inclined conveyor surface 200 to promote more effective separation of stacked lightweight objects.

[0083] For example, refer to Figure 7The first rotating connector 207 includes a first hinge seat 2070, a first pin 2072, a first mounting seat 2073, and a first rubber pad 2075. The first hinge seat 2070 is disposed on the third upright 2060 and has a first hinge seat pin hole 2071. The first mounting seat 2073 is disposed on the first rubber pad 2075 and has a first mounting hole 2074. The first pin 2072 is inserted into the first hinge seat pin hole 2071 and the first mounting hole 2074. The first rubber pad 2075 is disposed below the front end of the second base frame 205 in the vertical direction. This configuration, by inserting the first pin 2072 into the first hinge pin hole 2071 and the first mounting hole 2074, connects the first hinge seat 2070 on the third upright 2060 with the first mounting seat 2073 on the first rubber pad 2075, thereby forming a rotatable fulcrum below the front end of the second base frame 205. This structure allows the second base frame 205 to rotate around the first pin 2072 as the fulcrum, while the first rubber pad 2075 can buffer the vibration and impact generated during rotation.

[0084] For example, refer to Figure 8 The first lifting assembly 208 includes a first fisheye screw 2080, a first pin 2083, and a second rubber pad 2084. The first fisheye screw 2080 includes a first fisheye screw pin hole 2081 and a first fisheye screw threaded rod 2082. The first fisheye screw threaded rod 2082 is connected to the fourth upright 2061. By twisting the first fisheye screw threaded rod 2082, the first fisheye screw 2080 can be driven to extend or retract relative to the fourth upright 2061. It should be noted that the first fisheye screw threaded rod 2082 can also be connected to the fourth upright 2061 via a nut or other connecting assembly to achieve the extension and retraction of the first fisheye screw. The first pin 2083 is inserted into the first fisheye screw pin hole 2081, and both ends of the first pin 2083 are connected to the second rubber pad 2084. The second rubber pad 2084 is located below the rear end of the second base frame 205 along the vertical direction. This configuration allows the first spherical screw 2080 to be rotated so that its threaded shaft 2082 screws into or out of the fourth upright 2061, thereby changing the extension length of the first spherical screw 2080 from the fourth upright 2061. This, in turn, lifts or lowers the rear end of the second base frame 205 located above the fourth upright 2061. Simultaneously, the first pin 2083, inserted into the pin hole 2081 of the first spherical screw, transmits the lifting force to the second rubber pad 2084, ensuring that the second rubber pad 2084 remains in contact with the bottom surface of the second base frame 205, thus buffering local contact stress.

[0085] In some possible implementations, the angle range of the inclined conveyor surface 200 of this application is 18-25°. Specifically, for lightweight items weighing less than or equal to 1.5 kg, the angle range of the inclined conveyor surface 200 is 22°-25°, and for heavy items weighing more than 1.5 kg, the angle range is 18°-20°. For example, for lightweight items, the weights of the items are selected as 0.6 kg, 0.8 kg, 1.0 kg, 1.2 kg, and 1.5 kg, and the angles of the inclined conveyor surface 200 are set to 22°, 23°, and 25°. A larger angle provides sufficient gravitational force to the lightweight items, allowing them to overcome friction with other items on the upper layer, thus achieving separation and allowing them to continue being conveyed on the conveyor belt. However, when the angle is 21°, the angle is insufficient, and the lightweight items cannot overcome friction with other items, causing them to remain stacked or only partially separated. For heavy objects, the weights of the objects are selected as 1.6kg, 1.7kg, 1.9kg, 2.1kg and 2.3kg, and the rotation angle of the inclined conveyor surface 200 is set to 18°, 19° and 20°. The stacked objects can be separated while avoiding the slope being too steep, so that the heavy objects can move smoothly without violent sliding. The stacked objects can be separated. However, when the rotation angle is 21°, the inclination angle is slightly large, which causes the heavy objects to accelerate and slide down the inclined conveyor surface, which is difficult to control and is prone to collision between objects, causing damage to the objects.

[0086] refer to Figure 9A , Figure 9B and Figure 10AThe second drive assembly 202 includes a second conveyor belt 20200, a second drive roller 20201, a second driven roller 20202, a second drive motor 20203, and a third support side plate 20205 and a fourth support side plate 20206 disposed on both sides of the inclined conveying surface. Vertically, the third support side plate 20205 and the fourth support side plate 20206 are located below the second side baffle 201 and are disposed on both sides of the second conveyor belt 20200. Along the direction of conveying the object, the second drive roller 20201 is disposed at the end of the second conveyor belt 20200, and the second driven roller 20202 is disposed at the beginning of the second conveyor belt 20200. The second drive motor 20203 is positioned between the third support side plate 20205 and the fourth support side plate 20206. The second drive motor 20203 is connected to the third support side plate 20205 via a second drive motor mounting base 20204. The second drive motor drive shaft 202030 is connected to the third synchronous pulley 20207. The third synchronous pulley 20207 is connected to the fourth synchronous pulley 20208 via a second synchronous belt 20209. The fourth synchronous pulley 20208 is connected to the second drive roller drive shaft 202010, and is used to drive the second drive roller 20201 and the second driven roller 20202 to rotate. This arrangement provides mounting support and positioning for the second drive roller 20201, the second driven roller 20202, and the second drive motor 20203 on both sides of the second conveyor belt 20200. At the same time, the second drive motor 20203 drives the second conveyor belt 20200 to move, providing power for the inclined conveyor surface 200 to convey objects.

[0087] Furthermore, the third drive assembly 203 includes a third conveyor belt 20300, a third drive roller 20301, a third driven roller 20302, a third drive motor 20303, and a fifth support side plate 20305 and a sixth support side plate 20306 disposed on both sides of the inclined conveying surface 200. (Reference) Figure 9A , Figure 9B and Figure 10BAlong the direction of conveying objects, the second conveyor belt 20200 and the third conveyor belt 20300 are arranged sequentially. The conveying surfaces of the second conveyor belt 20200 and the third conveyor belt 20300 are inclined conveying surfaces 200. The second conveyor belt 20200 and the third conveyor belt 20300 are used to convey objects on the inclined conveying surfaces 200 to the second horizontal conveying surface 300. In the vertical direction, the fifth support side plate 20305 and the sixth support side plate 20306 are located below the second side baffle 201, and are arranged on both sides of the third conveyor belt 20300. Along the direction of conveying objects, the third drive roller 20301 is arranged at the starting end of the third conveyor belt 20300, and the third driven roller 20302 is arranged at the end of the third conveyor belt 20300. The starting end of the third conveyor belt 20300 is adjacent to the end of the second conveyor belt 20200. The third drive motor 20303 is positioned between the fifth support side plate 20305 and the sixth support side plate 20306. The third drive motor 20303 is connected to the fifth support side plate 20305 via a third drive motor mounting base 20304. The third drive motor 20303 is also connected to the fifth synchronous pulley 20307, ​​which is connected to the sixth synchronous pulley 20308 via a third synchronous belt 20309. The sixth synchronous pulley 20308 is connected to the drive shaft of the third drive roller 20301, driving both the third drive roller 20301 and the third driven roller 20302 to rotate. This arrangement, with the third conveyor belt 20300 and its associated drive components positioned behind the second conveyor belt 20200 along the direction of the conveyed object, extends the overall working length of the inclined conveyor surface 200. The third drive motor 20303 transmits power to the third drive roller 20301 via the fifth synchronous pulley 20307, ​​the third synchronous belt 20309, and the sixth synchronous pulley 20308, driving the third conveyor belt 20300 to rotate. The second conveyor belt 20200 works in conjunction with the third conveyor belt 20300, allowing objects to experience a longer acceleration and separation zone during the climbing process, providing more opportunities for stacked objects to slide and increase spacing. The fifth support side plate 20305 and the sixth support side plate 20306, located on both sides of the third conveyor belt 20300, provide mounting support and positioning for the third drive roller 20301, the third driven roller 20302, and the third drive motor 20303. Meanwhile, by driving the second conveyor belt 20200 and the third conveyor belt 20300 to rotate through the second drive motor 20203 and the third drive motor 20303 respectively, the object placed on the inclined conveyor surface 200 can be conveyed from the starting end to the end and further transferred to the second horizontal conveyor surface.

[0088] In some possible implementations, the second drive assembly 202 further includes a second roller adjustment assembly 20216 and a second guide wheel adjustment assembly 20219. The second roller adjustment assembly 20216 is disposed on the left and / or right side of the second roller mounting hole 20218 in the third support side plate 20205 and the fourth support side plate 20206 for accommodating the second driven roller drive shaft 202020. A second roller baffle 20217 is disposed on the left and / or right side of the second roller mounting hole 20218 to prevent the second driven roller drive shaft 202020 from dislodging from its mounting position during adjustment or operation. The second roller adjustment assembly 20216 includes a second nut plate 202160 and a second adjusting rod 202161 inserted into the second nut plate 202160. By rotating the second adjusting rod 202161, the axial position of the second driven roller drive shaft 202020 in the second roller mounting hole 20218 can be pushed, thereby adjusting the relative distance between the second driving roller 20201 and the second driven roller 20202, so as to adjust the tension of the second driving roller 20201, the second driven roller 20202, and the end of the second conveyor belt 20200. The second guide wheel adjustment assembly 20219 is located below the second roller adjustment assembly 20216 in the vertical direction. The second guide wheel adjustment assembly 20219 includes a second guide wheel mounting base 202192, a second guide wheel adjustment plate 202191, and a second guide wheel 202190 placed on the second guide wheel adjustment plate 202191. The second guide wheel adjustment plate 202191 is located above the second guide wheel mounting base 202192 in the vertical direction, and the second guide wheel 202190 is located on the second guide wheel adjustment plate 202191. The second guide wheel 202190 corrects the running trajectory of the second conveyor belt 20200 by contacting the side edge of the second conveyor belt 20200, preventing the second conveyor belt 20200 from deviating to one side and ensuring that the second conveyor belt 20200 runs smoothly and centrally.

[0089] Furthermore, the third drive assembly 203 also includes a third roller adjustment assembly 20316 and a third guide wheel adjustment assembly 20319. The third roller adjustment assembly 20316 is disposed on the left and / or right side of the third roller mounting hole 20318 in the fifth support side plate 20305 and the sixth support side plate 20306 for accommodating the third driven roller drive shaft 203020. A third roller baffle 20317 is disposed on the left and / or right side of the third roller mounting hole 20318 to prevent the third driven roller drive shaft 203020 from dislodging from its mounting position during adjustment or operation. The third roller adjustment assembly 20316 includes a third nut piece 203160 and a third adjusting rod 203161 inserted into the third nut piece 203160. By rotating the third adjusting rod 203161, the axial position of the third driven roller drive shaft 203020 in the third roller mounting hole 20318 can be pushed, thereby adjusting the relative distance between the third driving roller 20301 and the third driven roller 20302, so as to adjust the tension of the third driving roller 20301, the third driven roller 20302 and the end of the third conveyor belt 20300. The third guide wheel adjustment assembly 20319 is located below the third roller adjustment assembly 20316 in the vertical direction. The third guide wheel adjustment assembly 20319 includes a third guide wheel mounting base 203192, a third guide wheel adjustment plate 203191, and a third guide wheel 203190 placed on the third guide wheel adjustment plate 203191. The third guide wheel adjustment plate 203191 is located above the third guide wheel mounting base 203192 in the vertical direction, and the third guide wheel 203190 is located on the third guide wheel adjustment plate 203191. The third guide wheel 203190 contacts the side edge of the third conveyor belt 20300 to correct the running trajectory of the third conveyor belt 20300, prevent the third conveyor belt 20300 from deviating to one side, and ensure that the third conveyor belt 20300 runs smoothly and centrally.

[0090] Furthermore, the second drive component 202 of this application also includes a fifth protective cover 20213, a sixth protective cover 20214, and a seventh protective cover 20215. (Continue to refer to...) Figure 9A and Figure 9B The fifth protective cover 20213 and the sixth protective cover 20214 are mounted on the third support side plate 20205 and connected to the third support side plate 20205 via the fifth protective cover bracket 20210 and the sixth protective cover bracket 20211. The seventh protective cover 20215 is mounted on the fourth support side plate 20206 and connected to the fourth support side plate 20206 via the seventh protective cover bracket 20212. This arrangement can prevent external foreign objects from entering the second drive assembly 202 and prevent personnel limbs from coming into contact with the moving second conveyor belt 20200, second drive roller 20201, second driven roller 20202, and second synchronous belt 20209.

[0091] Furthermore, the third drive component 203 of this application also includes an eighth protective cover 20313, a ninth protective cover 20314, and a tenth protective cover 20315. (Continue to refer to...) Figure 9A and Figure 9B The eighth protective cover 20313 and the ninth protective cover 20314 are mounted on the fifth support side plate 20305 and connected to the fifth support side plate 20305 via the eighth protective cover bracket 20310 and the ninth protective cover bracket 20311. The tenth protective cover 20315 is mounted on the sixth support side plate 20306 and connected to the sixth support side plate 20306 via the tenth protective cover bracket 20312. This arrangement can prevent external foreign objects from entering the third drive assembly 203 and prevent personnel limbs from coming into contact with the moving third conveyor belt 20300, third drive roller 20301, third driven roller 20302, and third synchronous belt 20309.

[0092] In some possible implementations, the third conveying mechanism 30 further includes a third side baffle 301. The third side baffle 301 is disposed on both sides of the third conveying mechanism 30. This arrangement continuously restricts the lateral movement of the object during the conveying process on the second horizontal conveying surface 300, preventing the object from leaving the second horizontal conveying surface 300, thereby keeping the object moving stably along the predetermined path and reducing conveying interruptions or object losses caused by deviation or falling.

[0093] For example, refer to Figure 11A and Figure 11B The third conveying mechanism 30 of this application further includes a third base frame 303 and a third frame 304 for stably supporting the second horizontal conveying surface 300 and its fourth drive assembly 302, ensuring connection with the second conveying mechanism 20. The third frame 304 is provided with a fifth upright 3040 located at the front end of the third base frame 303, and a sixth upright 3041 located at the rear end of the third base frame 303. The height of the fifth upright 3040 is the same as the height of the sixth upright 3041. The fifth upright 3040 is provided with a second rotating connector 305, and the sixth upright 3041 is provided with a second lifting assembly 306. The second lifting assembly 306 is used to lift the rear end of the third base frame 303. When the second lifting component 306 is operated, it raises or lowers the rear end of the third base frame 303, causing the third base frame 303 to rotate around the second rotating connector 305 as a fulcrum. This directly changes the tilt angle of the second horizontal conveying surface 300 mounted on the third base frame 303. This design allows for flexible adjustment of the tilt angle of the second horizontal conveying surface 300 to accommodate changes in the height of the end of the tilted conveying surface 200, ensuring a smooth transition of objects between conveying mechanisms.

[0094] For example, refer to Figure 12 The second rotary connector 305 includes a second hinge seat 3050, a second pin 3052, a second mounting seat 3053, and a third rubber pad 3055. The second hinge seat 3050 is mounted on the fifth upright 3040 and has a second hinge seat pin hole 3051. The second mounting seat 3053 is mounted on the third rubber pad 3055 and has a second mounting hole 3054. The second pin 3052 is inserted into the second hinge seat pin hole 3051 and the second mounting hole 3054. The third rubber pad 3055 is located below the front end of the third base frame 303 along the vertical direction. This configuration, by inserting the second pin 3052 into the second hinge pin hole 3051 and the second mounting hole 3054, connects the second hinge seat 3050 on the fifth upright 3040 with the second mounting seat 3053 on the third rubber pad 3055, thereby forming a rotatable fulcrum below the front end of the third base frame 303. This structure allows the third base frame 303 to rotate with the second pin 3052 as the fulcrum, while the third rubber pad 3055 can buffer the vibration and impact generated during rotation.

[0095] For example, refer to Figure 13 The second lifting assembly 306 includes a second fisheye screw 3060, a second pin 3063, and a fourth rubber pad 3064. The second fisheye screw 3060 includes a second fisheye screw pin hole 3061 and a second fisheye screw threaded rod 3062. The second fisheye screw threaded rod 3062 is connected to the sixth upright 3041. By twisting the second fisheye screw threaded rod 3062, the second fisheye screw 3060 can be driven to extend or retract relative to the sixth upright. It should be noted that the second fisheye screw threaded rod 3062 can also be connected to the sixth upright 3041 via a nut or other connecting assembly to achieve the extension and retraction of the first fisheye screw. The second pin 3063 is inserted into the second fisheye screw pin hole 3061, and both ends of the second pin 3063 are connected to the fourth rubber pad 3064. The fourth rubber pad is located below the rear end of the third base frame 303 along the vertical direction. This configuration allows the second fisheye screw 3060 to be rotated so that its threaded shaft 3062 screws into or out of the sixth upright 3041, thereby changing the extension length of the second fisheye screw 3060 from the sixth upright 3041. This, in turn, lifts or lowers the rear end of the third base frame 303 located above the sixth upright 3041. Simultaneously, the second pin 3063, inserted into the pin hole 3061 of the second fisheye screw, transmits the lifting force to the fourth rubber pad 3064, ensuring that the fourth rubber pad 3064 remains in contact with the bottom surface of the third base frame 303, thus buffering local contact stress.

[0096] refer to Figures 14A to 15The fourth drive assembly 302 of this application includes a fourth conveyor belt 30200, a fourth drive roller 30201, a fourth driven roller 30202, a fourth drive motor 30203, and a seventh support side plate 30205 and an eighth support side plate 30206 disposed on both sides of the second horizontal conveying surface 300. The conveying surface of the fourth conveyor belt 30200 is the second horizontal conveying surface 300. In the vertical direction... Figure 11A and Figure 11B The diagram shows that the seventh support side plate 30205 and the eighth support side plate 30206 are located below the third side baffle 301. The fourth drive roller 30201 is located at the end of the second horizontal conveying surface 300, and the fourth driven roller 30202 is located at the beginning of the second horizontal conveying surface 300, for conveying objects on the second horizontal conveying surface 300. The fourth drive motor 30203 is disposed between the seventh support side plate 30205 and the eighth support side plate 30206. The fourth drive motor 30203 is connected to the seventh support side plate 30205 through the fourth drive motor mounting base 30204. The fourth drive motor transmission shaft 302030 is connected to the seventh synchronous pulley 30207. The seventh synchronous pulley 30207 is connected to the eighth synchronous pulley 30208 through the fourth synchronous belt 30209. The eighth synchronous pulley 30208 is connected to the fourth drive roller transmission shaft 302010, and is used to drive the fourth drive roller 30201 and the fourth driven roller 30202 to rotate. When the fourth drive motor drive shaft 302030 rotates, it drives the seventh synchronous pulley 30207 connected to it to rotate; the seventh synchronous pulley 30207 transmits the rotational motion to the eighth synchronous pulley 30208 through the fourth synchronous belt 30209; the eighth synchronous pulley 30208 drives the fourth drive roller drive shaft 302010 to rotate, thereby driving the fourth drive roller 30201 to rotate; through the friction between the fourth conveyor belt 30200 and the roller, the fourth driven roller 30202 rotates accordingly; finally, the fourth conveyor belt 30200 moves horizontally under the drive of the fourth drive roller 30201 and the fourth driven roller 30202, conveying the object placed on the second horizontal conveying surface 300 from the starting end to the end. With this configuration, the seventh support side plate 30205 and the eighth support side plate 30206 of the second horizontal conveying surface 300 provide mounting support and positioning for the fourth driving roller 30201, the fourth driven roller 30202 and the fourth drive motor 30203; at the same time, the fourth drive motor 30203 drives the fourth conveyor belt 30200 to rotate, which can transport the objects placed on it from the starting end to the end, ensuring the smooth operation of the objects during the conveying process.

[0097] In some possible embodiments, the fourth drive assembly 302 further includes a fourth roller adjustment assembly 30216 and a fourth guide wheel adjustment assembly 30219. The fourth roller adjustment assembly 30216 is disposed on the left and / or right side of the fourth roller mounting hole 30218 in the seventh support side plate 30205 and the eighth support side plate 30206 for housing the fourth driven roller drive shaft 302020. A fourth roller baffle 30217 is disposed on the left and / or right side of the fourth roller mounting hole 30218 to prevent the fourth driven roller drive shaft 302020 from dislodging from its mounting position during adjustment or operation. The fourth roller adjustment assembly 30216 includes a fourth nut plate 302160 and a fourth adjusting rod 302161 inserted into the fourth nut plate 302160. By rotating the fourth adjusting rod 302161, the axial position of the fourth driven roller drive shaft 302020 in the fourth roller mounting hole 30218 can be pushed, thereby adjusting the relative distance between the fourth driving roller 30201 and the fourth driven roller 30202, so as to adjust the tension of the fourth driving roller 30201, the fourth driven roller 30202 and the end of the fourth conveyor belt 30200. The fourth guide wheel adjustment assembly 30219 is located below the fourth roller adjustment assembly 30216 in the vertical direction. The fourth guide wheel adjustment assembly 30219 includes a fourth guide wheel mounting base 302192, a fourth guide wheel adjustment plate 302191, and a fourth guide wheel 302190 placed on the fourth guide wheel adjustment plate 302191. The fourth guide wheel adjustment plate 302191 is located above the fourth guide wheel mounting base 302192 in the vertical direction, and the fourth guide wheel 302190 is located on the fourth guide wheel adjustment plate 302191. The fourth guide wheel 302190 corrects the running trajectory of the fourth conveyor belt 30200 by contacting the side edge of the fourth conveyor belt 30200, preventing the fourth conveyor belt 30200 from deviating to one side and ensuring that the fourth conveyor belt 30200 runs smoothly and centrally.

[0098] Furthermore, the fourth drive assembly 302 of this application also includes an eleventh protective shield 30213, a twelfth protective shield 30214, and a thirteenth protective shield 30215. (Continue to refer to...) Figure 14A and Figure 14BThe eleventh protective cover 30213 and the twelfth protective cover 30214 are mounted on the seventh support side plate 30205 and connected to the seventh support side plate 30205 via the eleventh protective cover bracket 30210 and the twelfth protective cover bracket 30211; the thirteenth protective cover 30215 is mounted on the eighth support side plate 30206 and connected to the eighth support side plate 30206 via the thirteenth protective cover bracket 30212. This arrangement can prevent external foreign objects from entering the fourth drive assembly 302 and prevent personnel limbs from coming into contact with the moving fourth conveyor belt 30200, fourth drive roller 30201, fourth driven roller 30202, and fourth synchronous belt 30209.

[0099] It should be noted that the protective covers of this application adopt both a split-type and a one-piece design. The split-type protective cover is used for the drive component parts that require frequent maintenance, and the split design facilitates subsequent maintenance and replacement.
