Description

Technical Field

[0001] The present invention relates to a conveying device, and more particularly to a gravity-driven conveying device. Background Art

[0002] In a production line with manual participation in processing, operators usually have fixed operating stations. Due to the space limitation of the operating stations, only a small number of material boxes containing materials can be placed nearby. Therefore, operators need to frequently leave the operating stations to carry materials, which not only consumes the physical strength of the operators but also reduces production efficiency. To solve the above problems, some current production lines will set up automatic conveying devices for operators. The existing automatic conveying devices have high manufacturing costs and also require additional consumption of energy such as electricity or gas. Summary of the Invention

[0003] The object of the present invention is to provide a conveying device with low manufacturing cost, which is gravity-driven and does not require energy consumption.

[0004] The present invention provides a conveying device, which includes a frame, a rack assembly, a sliding blanking rack, and a material taking platform. The frame has a vertical direction, and the vertical direction is parallel to the gravity direction after the frame is set on the ground. The rack assembly is arranged on the frame. The rack assembly has a first feeding end, a first discharging end, and a feeding platform. The material box can enter the rack assembly from the first feeding end and move to the first discharging end under the action of gravity and then slide into the feeding platform. The sliding blanking rack is arranged on the frame. The sliding blanking rack has a second feeding end and a second discharging end. The material box can enter the sliding blanking rack from the second feeding end and slide towards the second discharging end under the action of gravity. The material taking platform is rotatably arranged on the frame around an axis perpendicular to the vertical direction between a first holding position and a first inclined position. The material box on the feeding platform can slide into the material taking platform to make the material taking platform located at the first holding position. The material taking platform can be rotated from the first holding position to the first inclined position under the drive of an external force, so that the material box on the material taking platform slides into the second feeding end under the action of gravity.

[0005] The conveying device provided by the present invention is provided with a rack assembly for storing a plurality of material boxes. The material boxes stored on the rack assembly can automatically enter the material taking platform in sequence under the action of gravity for processing and material taking. The empty material boxes on the material taking platform can enter the sliding blanking rack and be stored under the action of gravity. Operators can process more materials without leaving the operating stations, saving physical strength and improving production efficiency at the same time. Moreover, the conveying device provided by the present invention has low manufacturing cost, is gravity-driven, and does not require energy consumption.

[0006] In a schematic embodiment of the conveying device, the conveying device further includes a first locking member and a linkage assembly. The first locking member is movably disposed on the frame body between a first locking position and a first release position. The first locking member is held at the first locking position when the material taking platform is in the first holding position. The first locking member at the first locking position can block the material box from sliding into the feeding platform from the first discharging end. The first locking member at the first release position can avoid the material box so that it can slide into the feeding platform from the first discharging end. The linkage assembly connects the material taking platform and the first locking member. During the process of the material taking platform rotating from the first holding position to the first inclined position, the first locking member can be driven by the linkage assembly to move from the first locking position to the first release position. Thereby, it is avoided that a plurality of material boxes are stacked on the feeding platform, which is not convenient for a single material box to enter the material taking platform.

[0007] In a schematic embodiment of the conveying device, the conveying device further includes a first rotating frame. The first rotating frame is rotatably disposed on the frame body around an axis perpendicular to the vertical direction. The first locking member is disposed on the first rotating frame. When the material taking platform is in the first holding position, the first rotating frame keeps the first locking member at the first locking position under the action of an elastic member. During the process of the material taking platform rotating from the first holding position to the first inclined position, the first rotating frame can be driven to rotate by the linkage assembly so that the first locking member moves to the first release position. This structure is simple and convenient for processing to save manufacturing costs.

[0008] In a schematic embodiment of the conveying device, the linkage assembly includes several first fixed pulleys and a first rope. Each first fixed pulley is disposed on the frame body. The first rope bypasses several first fixed pulleys, and both ends are connected to the material taking platform and the first rotating frame. This structure is simple and convenient for processing to save manufacturing costs.

[0009] In a schematic embodiment of the conveying device, the rack assembly includes a first sliding loading rack, a second sliding loading rack, and a conveying platform. One end of the first sliding loading rack away from the ground in the vertical direction is the first feeding end, and the first sliding loading rack also has a first lifting and conveying end close to the ground. The material box can enter the first sliding loading rack from the first feeding end and slide towards the first lifting and conveying end under the drive of gravity. One end of the second sliding loading rack close to the ground in the vertical direction is the first discharging end, and the second sliding loading rack also has a second lifting and conveying end away from the ground. The material box can enter the second sliding loading rack from the second lifting and conveying end and slide towards the first discharging end under the drive of gravity. The second lifting and conveying end is located on the side close to the ground of the first lifting and conveying end in the vertical direction. The conveying platform is movably arranged on the frame body between a receiving position away from the ground and a feeding position close to the ground in the vertical direction. The conveying platform is connected to a first counterweight through a second rope, and the second rope bypasses a second fixed pulley, enabling the conveying platform to move to the receiving position under the drive of the gravity of the first counterweight. The material box located at the first lifting and conveying end can slide into the conveying platform. After the material box slides into the conveying platform, the conveying platform can move to the feeding position under the drive of gravity, and the material box on the conveying platform can slide into the second lifting and conveying end. Thereby, the utilization rate of the three-dimensional space can be improved, and more material boxes can be stored to improve the efficiency.

[0010] In a schematic embodiment of the conveying device, the conveying platform is rotatably arranged on the frame body between a second holding position and a second inclined position around an axis perpendicular to the vertical direction. The conveying platform remains in the second holding position after the material box slides in. During the movement towards the feeding position, a part of the conveying platform is blocked by the frame body, causing the conveying platform to rotate to the second inclined position when moving to the feeding position, and the material box on the conveying platform can slide into the second lifting and conveying end under the drive of gravity.

[0011] In a schematic embodiment of the conveying device, the rack assembly further includes a first sliding frame, which is movably arranged on the frame body in the vertical direction. The conveying platform is rotatably arranged on the first sliding frame between the second holding position and the second inclined position. The conveying platform is connected to the second rope through the first sliding frame. This structure is simple and convenient for processing to save manufacturing costs.

[0012] In a schematic embodiment of the conveying device, the first sliding frame includes a first connecting shaft perpendicular to the vertical direction, and the conveying platform is rotatably connected to the first connecting shaft. The frame body also includes a first blocking portion. During the movement of the first sliding frame in the vertical direction and driving the conveying platform towards the feeding position, a part of the conveying platform is blocked by the first blocking portion.

[0013] In a schematic embodiment of the conveying device, the rack assembly further includes a second locking member, which is movably disposed on the rack between a second locking position and a second releasing position. The second locking member located at the second locking position can block the material box from sliding out of the first lifting and conveying end, and the second locking member located at the second releasing position can avoid the material box so that it can slide out of the first lifting and conveying end. The second locking member is held at the second locking position when the conveying platform leaves the material receiving position, and the conveying platform can drive the second locking member to move to the second releasing position when it moves to the material receiving position. In this way, one material box is conveyed for each reciprocating movement of the conveying platform.

[0014] In a schematic embodiment of the conveying device, the rack assembly further includes a second rotating rack, which is rotatably disposed on the rack around an axis perpendicular to the vertical direction. The second locking member is disposed on the second rotating rack. When the conveying platform leaves the material receiving position, the second rotating rack rotates under the drive of gravity and keeps the second locking member at the second locking position. When the conveying platform moves to the material receiving position, it can push the second rotating rack to rotate so that the second locking member moves to the second releasing position. This structure is simple and convenient for processing to save manufacturing costs.

[0015] In a schematic embodiment of the conveying device, the first sliding loading rack, the second sliding loading rack and the sliding unloading rack all include roller-type conveying roller paths. The conveying device further includes several pairs of guardrails, which are disposed on the rack and are respectively located on both sides of the first sliding loading rack, the second sliding loading rack and the sliding unloading rack to prevent the material box from sliding off both sides of the first sliding loading rack, the second sliding loading rack and the sliding unloading rack. In this way, the material box is protected.

[0016] In a schematic embodiment of the conveying device, the conveying device further includes a loading platform and a loading handle. The loading platform is movably disposed on the rack along the vertical direction between a loading position close to the ground and a feeding position away from the ground, and the loading platform is also rotatably disposed on the rack around an axis perpendicular to the vertical direction between a third holding position and a third inclined position. The loading platform is held at the third holding position after the material box is placed. During the movement towards the feeding position, a part of the loading platform is blocked by the rack so that the loading platform rotates to the third inclined position when it moves to the feeding position, enabling the material box on the loading platform to slide into the first feeding end under the drive of gravity. The loading handle is connected to the loading platform through a third rope, and the third rope bypasses several third fixed pulleys, so that when the loading handle moves vertically towards the ground under the drive of an external force, it can drive the loading platform to move from the loading position to the feeding position. In this way, it is convenient to place the material box into the first feeding end to achieve loading.

[0017] In a schematic embodiment of the conveying device, the rack assembly further includes a second sliding rack, which is movably arranged on the rack body in the vertical direction. The loading platform is rotatably arranged on the second sliding rack between a third holding position and a third inclined position. The loading platform is connected to the third rope through the second sliding rack. This structure is simple and easy to process to save manufacturing costs.

[0018] In a schematic embodiment of the conveying device, the second sliding rack includes a second connecting shaft perpendicular to the vertical direction, and the loading platform is rotatably connected to the second connecting shaft. The rack body further includes a second blocking portion. During the process of the second sliding rack moving in the vertical direction and driving the loading platform to move towards the feeding position, a part of the loading platform is blocked by the second blocking portion.

[0019] In a schematic embodiment of the conveying device, the conveying device further includes a second counterweight, which is connected to the loading platform through a fourth rope. The fourth rope bypasses a fourth fixed pulley, so that the gravity of the second counterweight acts on the loading platform in the opposite direction of gravity. This can reduce the physical effort during the loading process.

[0020] In a schematic embodiment of the conveying device, the feeding platform is rotatably arranged on the rack body between a receiving holding position and a fourth inclined position around an axis perpendicular to the vertical direction. The feeding platform remains in the fourth inclined position after the material box slides in, and the feeding platform remains in the receiving holding position and perpendicular to the vertical direction after the material box slides out. This can convey the material box more stably.

[0021] In a schematic embodiment of the conveying device, the conveying device further includes an operation table board, which is arranged on the rack body and close to the material taking platform. This is convenient for the operator to directly obtain materials from the material taking platform for processing.

[0022] In a schematic embodiment of the conveying device, the conveying device further includes an operation handle, which is arranged on the material taking platform and is convenient to grip. This is convenient for the operator to drive the material taking platform to rotate, and at the same time improves the safety of operation and prevents pinching. Description of the Drawings

[0086] For a clearer understanding of the technical features, objectives and effects of the invention, the detailed implementation manners of the invention are now described with reference to the accompanying drawings. In the drawings, the same reference numerals denote components having the same or similar structures but the same functions.

[0087] In this document, "schematic" means "serving as an example, instance or illustration", and any illustration or implementation manner described as "schematic" in this document should not be construed as a more preferred or more advantageous technical solution.

[0088] In this document, "first", "second", "third", "fourth", etc. do not indicate their importance or order, etc., but are only used to indicate their differences from each other for the convenience of document description.

[0089] For the sake of simplicity of the drawings, only the parts related to the invention are schematically shown in each drawing, and they do not represent the actual structure of the product.

[0090] Figure 1 It is a schematic structural diagram for illustrating a schematic implementation manner of a conveying device. Figure 2 It is a schematic structural diagram for illustrating another perspective of the conveying device. Refer to Figure 1 and Figure 2 , the conveying device includes a frame 10, a rack assembly 20, a sliding blanking rack 30 and a material taking platform 40. The frame 10 has a vertical direction G, and the vertical direction G is parallel to the gravity direction after the frame 10 is arranged on the ground.

[0091] The rack assembly 20 is arranged on the frame 10. The rack assembly 20 has a first feeding end 211, a first discharging end 222 and a feeding platform 23. The material box 80 can enter the rack assembly 20 from the first feeding end 211, and move to the first discharging end 222 under the drive of gravity and then slide into the feeding platform 23. The rack assembly 20 can store a plurality of material boxes 80 between the first feeding end 211 and the first discharging end 222. Figure 3 and Figure 4It is a partial structural schematic diagram for explaining the working state of the conveying device. Refer to Figure 2 , Figure 3 and Figure 4 , in the illustrative embodiment, the rack assembly 20 includes a first sliding loading rack 21, a second sliding loading rack 22, and a conveying platform 241.

[0092] Refer to Figure 2 , one end of the first sliding loading rack 21 away from the ground along the vertical direction G is the first feeding end 211, and the first sliding loading rack 21 also has a first lifting and conveying end 212 close to the ground. The material box 80 can enter the first sliding loading rack 21 from the first feeding end 211 and slide towards the first lifting and conveying end 212 under the drive of gravity. One end of the second sliding loading rack 22 close to the ground along the vertical direction G is the first discharging end 222, and the second sliding loading rack 22 also has a second lifting and conveying end 221 away from the ground. The material box 80 can enter the second sliding loading rack 22 from the second lifting and conveying end 221 and slide towards the first discharging end 222 under the drive of gravity. The second lifting and conveying end 221 is located on the side close to the ground of the first lifting and conveying end 212 along the vertical direction G.

[0093] Refer to Figure 3 and Figure 4 , the conveying platform 241 is movably arranged on the frame 10 along the vertical direction G between a material receiving position away from the ground as shown in Figure 3 and a material feeding position close to the ground as shown in Figure 4 . The conveying platform 241 is connected to a first counterweight 242 through a second rope 243. The second rope 243 bypasses a second fixed pulley 244. The gravity of the first counterweight 242 acts on the conveying platform 241 in the reverse direction, enabling the conveying platform 241 to move to the material receiving position under the drive of the gravity of the first counterweight 242. The material box 80 located at the first lifting and conveying end 212 can slide into the conveying platform 241. After the material box 80 slides into the conveying platform 241, the conveying platform 241 can move to the material feeding position under the drive of gravity, overcoming the gravity of the first counterweight 242. The material box 80 on the conveying platform 241 can slide into the second lifting and conveying end 221. The above multi-section three-dimensional structure of the rack assembly 20 can improve the utilization rate of the three-dimensional space and store more material boxes 80 to improve efficiency. However, it is not limited to this. In other illustrative embodiments, the rack assembly 20 can also be a single-section structure.

[0094] Refer to Figure 1 and Figure 2, the sliding blanking rack 30 is arranged on the rack body 10. The sliding blanking rack 30 has a second feeding end 31 and a second discharging end 32. The material box 80 can enter the sliding blanking rack 30 from the second feeding end 31 and slide towards the second discharging end 32 under the drive of gravity. The rack body 10 is provided with a stop structure at the second discharging end 32, and multiple material boxes 80 can be stored between the second discharging end 32 and the second discharging end 32.

[0095] Figure 5 and Figure 6 is a partial structural schematic diagram for illustrating a working state of the conveying device. Refer to Figure 2 、 Figure 5 and Figure 6 , the material taking platform 40 is rotatably arranged on the rack body 10 around an axis S3 between a first holding position as shown in Figure 5 and a first inclined position as shown in Figure 6 . The axis S3 is parallel to a second horizontal direction B perpendicular to the vertical direction G. The material box 80 on the feeding platform 23 can slide into the material taking platform 40, so that the material taking platform 40 abuts against the rack body 10 under the action of gravity and remains in the first holding position. At this time, the material box 80 will not move relative to the material taking platform 40, and the operator can take materials from the material box 80 for processing. After the materials in the material box 80 are taken out, the material taking platform 40 can be rotated from the first holding position to the first inclined position under the external force drive of the operator, so that the empty material box 80 on the material taking platform 40 slides into the second feeding end 31 under the drive of gravity, completing the storage of the empty material box 80.

[0096] For the conveying device provided by the present invention, a rack assembly 20 is arranged for storing multiple material boxes 80. The material boxes 80 stored on the rack assembly 20 can automatically enter the material taking platform 40 in sequence under the action of gravity for processing and taking materials. The empty material boxes 80 on the material taking platform 40 can enter the sliding blanking rack 30 and be stored under the action of gravity. The operator can process more materials without leaving the operation station, saving physical strength and improving production efficiency at the same time. Moreover, the conveying device provided by the present invention has a low manufacturing cost, relies on gravity drive, and does not require energy consumption.

[0097] In the schematic embodiment, refer to Figure 1 and Figure 2 , the first sliding feeding rack 21, the second sliding feeding rack 22 and the sliding blanking rack 30 all include roller-type conveying roller paths. Refer to Figure 2, the conveying device further includes several pairs of guardrails 11, which are arranged on the frame body 10 and are respectively located on both sides of the first sliding loading rack 21, the second sliding loading rack 22 and the sliding unloading rack 30 to prevent the material box 80 from sliding off both sides of the first sliding loading rack 21, the second sliding loading rack 22 and the sliding unloading rack 30. Thereby, the material box 80 is protected.

[0098] In a schematic embodiment, referring to Figure 3 and Figure 4 , the rack assembly 20 further includes a first sliding rack 13, which is movably arranged on the frame body 10 along the vertical direction G. The conveying platform 241 is arranged on the first sliding rack 13, and the conveying platform 241 is connected to the second rope 243 through the first sliding rack 13. When no material box 80 is stored on the conveying platform 241, the total weight of the conveying platform 241 and the first sliding rack 13 is less than the weight of the first counterweight 242. At this time, the conveying platform 241 is driven to rise and move towards the receiving position. After the material box 80 slides into the conveying platform 241, the total weight of the conveying platform 241, the first sliding rack 13 and the material box 80 is greater than the weight of the first counterweight 242. At this time, the conveying platform 241 is driven to descend and move towards the feeding position. The above simple structure realizes the reciprocating lifting movement of the conveying platform 241, and at the same time is convenient for processing to save manufacturing costs.

[0099] In a schematic embodiment, referring to Figure 3 and Figure 4 , the first sliding rack 13 includes a first connecting shaft 131 perpendicular to the vertical direction G. The conveying platform 241 is rotatably connected to the first connecting shaft 131 between a second holding position as shown in Figure 3 and a second inclined position as shown in Figure 4 around an axis S1. The axis S1 is parallel to a first horizontal direction A that is respectively perpendicular to the vertical direction G and the second horizontal direction B. After the material box 80 slides into the conveying platform 241, the conveying platform 241 is kept in the second holding position by abutting against the first sliding rack 13. At this time, the material box 80 will not move relative to the conveying platform 241. The frame body further includes a first blocking portion 15. During the process that the first sliding rack 13 moves along the vertical direction G and drives the conveying platform 241 to move towards the feeding position, a part of the conveying platform 241 is blocked by the first blocking portion 15, and another part of the conveying platform 241 continues to move due to being connected to the first connecting shaft 131, so that the conveying platform 241 rotates to the second inclined position when moving to the feeding position. At this time, the material box 80 on the conveying platform 241 can slide into the second lifting and conveying end 221 under the drive of gravity.

[0100] In a schematic embodiment, referring to Figure 3 and Figure 4, the rack assembly 20 further includes a second locking member 251, which is movably disposed on the rack body 10 between a second locking position as shown in Figure 4 and a second releasing position as shown in (obscured and not shown) Figure 3 . The second locking member 251 located at the second locking position can block the material box 80 from sliding out of the first lifting and conveying end 212. The second locking member 251 located at the second releasing position can avoid the material box 80 so that it can slide out of the first lifting and conveying end 212. The second locking member 251 is held at the second locking position when the conveying platform 241 leaves the material receiving position. When the conveying platform 241 moves to the material receiving position, it can drive the second locking member 251 to move to the second releasing position. Thereby, when the conveying platform 241 leaves the material receiving position, the material box 80 cannot slide out of the first lifting and conveying end 212, and the conveying platform 241 conveys one material box 80 each time it reciprocates.

[0101] Specifically, referring to Figure 3 and Figure 4 , the rack assembly 20 further includes a second rotating frame 252, and the second rotating frame 252 is rotatably disposed on the rack body 10 around an axis S0 parallel to the first horizontal direction A. The second locking member 251 is disposed on the second rotating frame 252. When the conveying platform 241 leaves the material receiving position, the second rotating frame 252 rotates under the drive of gravity and keeps the second locking member 251 at the second locking position. When the conveying platform 241 moves to the material receiving position, it can push the second rotating frame 252 to rotate so that the second locking member 251 moves to the second releasing position. The above simple structure realizes the linkage between the second locking member 251 and the conveying platform 241, and is convenient for processing to save manufacturing costs.

[0102] In the illustrative embodiment, referring to Figure 5 and Figure 6 , the conveying device further includes an operating handle 41, which is disposed on the material taking platform 40 and is convenient for grasping. Thereby, it is convenient for the operator to drive the material taking platform 40 to rotate, and at the same time improves the safety of operation and prevents pinching.

[0103] In the illustrative embodiment, referring to Figure 5 and Figure 6 , the feeding platform 23 rotates around an axis S2 parallel to the second horizontal direction B between a material receiving and holding position as shown in Figure 6 and a Figure 5is rotatably disposed on the frame 10 between the shown fourth inclined positions. The feeding platform 23 remains at the fourth inclined position after the material box 80 slides in, and the feeding platform 23 remains at the receiving and holding position and is perpendicular to the vertical direction G after the material box 80 slides out. Thus, when the material box 80 slides in from the first discharge end 222, the feeding platform 23 can stably receive it, and then the feeding platform 23 rotates to make the material box 80 slide into the material taking platform 40, thereby more stably conveying the material box 80.

[0104] Figure 7 is a schematic partial structure diagram for explaining the conveying device. Refer to Figure 5 、 Figure 6 and Figure 7 , in the illustrative embodiment, the conveying device further includes a first locking member 51 and a linkage assembly. The first locking member 51 is movably disposed on the frame 10 between a first locking position as shown in Figure 5 and a first release position as shown in Figure 6 (blocked and not shown). The first locking member 51 is held at the first locking position when the material taking platform 40 is in the first holding position. The first locking member 51 at the first locking position can block the material box 80 from sliding into the feeding platform 23 from the first discharge end 222, and the first locking member 51 at the first release position can avoid the material box 80 so that it can slide into the feeding platform 23 from the first discharge end 222. The linkage assembly connects the material taking platform 40 and the first locking member 51. During the process of the material taking platform 40 rotating from the first holding position to the first inclined position, it can drive the first locking member 51 to move from the first locking position to the first release position through the linkage assembly. Thus, it is avoided that multiple material boxes 80 are stacked on the feeding platform 23, and it is convenient for a single material box 80 to enter the material taking platform 40.

[0105] Specifically, referring to Figure 7 , the conveying device further includes a first rotating frame 52. The first rotating frame 52 is rotatably disposed on the frame 10 around an axis S5 parallel to the first direction A. The first locking member 51 is disposed on the first rotating frame 52. When the material taking platform 40 is in the first holding position, the first rotating frame 52 keeps the first locking member 51 at the first locking position under the action of an elastic member 53. The linkage assembly includes several first fixed pulleys 61 and a first rope 62. Each first fixed pulley 61 is disposed on the frame 10. The first rope 62 bypasses several first fixed pulleys 61, and both ends are connected to the material taking platform 40 and the first rotating frame 52. During the process of the material taking platform 40 rotating from the first holding position to the first inclined position, it can pull the first rotating frame 52 to rotate through the first rope 62 to make the first locking member 51 move to the first release position. The above simple structure realizes the linkage between the first locking member 51 and the material taking platform 40, and is convenient for processing to save manufacturing costs.

[0106] Figure 8 is another partial structural schematic diagram for illustrating the conveying device. Refer to Figure 1 , Figure 2 and Figure 8 , the conveying device further includes a loading platform 71 and a loading handle 72.

[0107] Figure 9 and Figure 10 are partial structural schematic diagrams for illustrating the working state of the conveying device. Refer to Figure 8 , Figure 9 and Figure 10 , the loading platform 71 is movably arranged on the frame 10 along the vertical direction G between a loading position near the ground as shown in Figure 9 and a feeding position far from the ground as shown in Figure 10 . Specifically, the rack assembly 20 further includes a second sliding rack 14 which is movably arranged on the frame 10 along the vertical direction G. The second sliding rack 14 includes a second connecting shaft 141 perpendicular to the vertical direction G. The loading platform 71 is rotatably connected to the second connecting shaft 141 between a third holding position as shown in Figure 9 and a third inclined position as shown in Figure 10 around an axis S4 parallel to the first horizontal direction A. The loading platform 71 remains in the third holding position after the material box 80 is placed, and at this time the material box 80 will not move relative to the loading platform 71. The frame 10 further includes a second blocking portion 16. During the process that the second sliding rack 14 moves along the vertical direction G and drives the loading platform 71 to move towards the feeding position, a part of the loading platform 71 is blocked by the second blocking portion 16, and another part of the loading platform 71 continues to move due to being connected to the second connecting shaft 141, so that the loading platform 71 rotates to the third inclined position when moving to the feeding position, enabling the material box 80 on the loading platform 71 to slide into the first feeding end 211 under the drive of gravity.

[0108] The loading handle 72 is connected to the second sliding rack 14 through two third ropes 73. The two third ropes 73 bypass several third fixed pulleys 74, so that when the loading handle 72 moves towards the ground along the vertical direction G under the drive of an external force, it can drive the second sliding rack 14 to move along the vertical direction G, and further drive the loading platform 71 to move from the loading position to the feeding position. This facilitates placing the material box 80 into the first feeding end 211 to achieve feeding. Although the illustrative embodiment includes two third ropes 73 and two third fixed pulleys 74, it is not limited thereto. In other illustrative embodiments, the number of the third ropes 73 and the third fixed pulleys 74 can be adjusted according to the actual situation. Of course, it can also include only one third rope 73 and one third fixed pulley 74.

[0109] In a schematic embodiment, referring to Figure 8 , Figure 9 and Figure 10 , the conveying device further includes a second counterweight 75, which is connected to the loading platform 71 by two fourth ropes 76. The two fourth ropes 76 bypass two fourth fixed pulleys 77, so that the gravity of the second counterweight 75 acts on the loading platform 71 in the opposite direction of gravity, thereby reducing the force that needs to be applied to the loading handle 72 during the loading process, and further reducing the physical exertion of the operator. Although the schematic embodiment includes two fourth ropes 76 and two fourth fixed pulleys 77, it is not limited thereto. In other schematic embodiments, the number of the fourth ropes 76 and the fourth fixed pulleys 77 can be adjusted according to actual situations. Of course, it can also include only one fourth rope 76 and one fourth fixed pulley 77.

[0110] Figure 11 FIG. is a schematic structural diagram for illustrating another schematic embodiment of the conveying device. Referring to Figure 11 , which is the same as or similar to the conveying device in Figure 1 will not be described in detail. The difference is that the conveying device further includes an operation table board 12, which is arranged on the frame 10 and close to the material taking platform 40. Thereby, it is convenient for the operator to directly obtain materials from the material taking platform 40 for processing.
