The first translation mechanism moves in the opposite direction, driving the material layer on the belt platform component to complete the transfer.

Description

Technical Field

[0001] This invention relates to the field of layered material handling equipment technology, and specifically to an automatic layered material handling conveyor. Background Technology

[0002] Currently, the packaging and printing industry typically stacks semi-finished products into paper stacks for process flow. When these paper stacks need to be retrieved layer by layer at a certain process point, there is practically no available layer-by-layer material retrieval equipment, especially equipment capable of automatically layering and transferring the material. Currently, the domestic layer-by-layer paper retrieval process still relies on manual separation of paper layers before handling, which is labor-intensive. Some related equipment explores inserting layers from all four sides of the paper stack before hoisting, but this equipment is limited by the length and width of the layered paper stack, has a complex structure, low operating efficiency, and cannot handle layer-by-layer retrieval of paper stacks with special shapes, such as wavy or warped shapes, which can easily damage the effective parts of the paper. Therefore, there is a lack of feasible equipment in this field for achieving automated layer-by-layer material retrieval and transfer. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic layered material handling and conveying machine that solves the problem in the prior art that it is impossible to automatically layer and handle paper stacks of different types and transfer them.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] An automatic layered material handling conveyor includes:

[0006] A frame, on which a first lifting mechanism is provided;

[0007] The bracket is connected to the first lifting mechanism;

[0008] A belt platform assembly, mounted on the bracket, includes a transmission belt and a drive structure for moving the transmission belt;

[0009] The first translation mechanism drives the belt platform assembly to move horizontally.

[0010] The material distribution assembly includes a support frame mounted on the bracket, a second lifting mechanism mounted on the support frame, a crossbeam lifting plate connected to the second lifting mechanism, and a material distribution mechanism and several rotary clamping cylinders arranged side by side on the crossbeam lifting plate. Each rotary clamping cylinder has a support block on its cylinder rod.

[0011] The second translation mechanism drives the material distribution component to move horizontally.

[0012] The material distribution mechanism includes an insert plate and a third lifting mechanism that drives the insert plate to move up and down. After the second translation mechanism drives the insert plate to insert into the material pile, the third lifting mechanism drives the insert plate to move upward, creating a gap between the material layers. Several rotary clamping cylinders sequentially drive the support block to insert into the gap and lift it, so that one side of the separated material layer is completely lifted. The first translation mechanism drives the belt platform assembly to move into the gap and support the material layer. After the second translation mechanism moves in the opposite direction and resets, the second lifting mechanism lifts the material distribution mechanism and the rotary clamping cylinders again. The conveyor belt rotates to move the separated material layer onto the conveyor belt, realizing safe, fast and stable layered material removal from the material pile.

[0013] As a further embodiment of the present invention: the insert plate includes a main insert plate and a secondary insert plate, and the material distribution assembly further includes a support structure, a fixing frame, a main insert plate fixing plate, a first telescopic guide rail structure, a first rack, a second rack, a rotating shaft, a first gear, and a second gear. The third lifting mechanism is mounted on the support structure to drive the fixing frame to move up and down. The secondary insert plate is fixed to the bottom of the fixing frame, and the main insert plate is fixed to the main insert plate fixing plate and disposed at the bottom of the secondary insert plate. The main insert plate fixing plate is slidably connected to the fixing frame through the first telescopic guide rail structure. The first rack is disposed on the main insert plate fixing plate, and the second rack is located on one side of the fixing frame. The rotating shaft is rotatably connected to the fixing frame through a bearing. The first gear and the second gear are both fixed on the rotating shaft. The first gear meshes with the first rack, and the second gear meshes with the second rack. When the third lifting mechanism drives the second gear to rise, the second gear rolls upward along the second rack and synchronously drives the front end of the main insert plate to extend out of the front end of the secondary insert plate, thereby reducing the damage range of the material to the material when the material distribution mechanism is inserted into the material pile for stratification.

[0014] As a further aspect of the present invention: the fixing frame is provided with a stop plate for limiting the main insert plate fixing plate; the second rack is connected to the support structure through a buffer member; the buffer member includes an upper support for a guide rod, a guide rod passing through a mounting hole in the upper support for the guide rod, a limiting member at the top of the guide rod, a lower support for the guide rod at the bottom of the guide rod, and a buffer spring between the upper support for the guide rod and the lower support for the guide rod; the guide rod is clearance-fitted with the mounting hole; the second rack is fixed at the bottom end of the lower support for the guide rod; after the main insert plate fixing plate contacts the stop protrusion of the stop plate, the buffer spring is compressed, so that the third lifting mechanism can drive the main insert plate to synchronously extend and retract horizontally during the partial stage of vertical lifting.

[0015] As a further embodiment of the present invention: the fixing frame includes a sliding plate, a left support plate and a right support plate disposed on both sides of the front of the sliding plate, and a stop plate disposed at the bottom of the left support plate; the lifting slider of the third lifting mechanism is fixedly disposed on the back of the sliding plate; the rotating shaft is rotatably connected to the left support plate and the right support plate through bearings; the first gear and the second gear are respectively fixed at both ends of the rotating shaft and located on the inner and outer sides of the right support plate; the main insert plate fixing plate is slidably connected to the inner side wall of the right support plate through the first telescopic guide rail structure; and the auxiliary insert plate is fixed to the front end of the bottom of the stop plate and extends out of the stop plate.

[0016] As a further aspect of the present invention, the length of the main insert plate is greater than the length of the secondary insert plate.

[0017] As a further aspect of the present invention: the cylinder rod of the rotary clamping cylinder is connected to the tail of the support block, so that the rotary clamping cylinder can drive the support block to rotate 90 degrees into the gap area.

[0018] As a further embodiment of the present invention: the first lifting mechanism includes a lead screw, a first lifting motor that drives the lead screw to rotate, a nut block that is threadedly connected to the lead screw, a pair of support plates disposed at both ends of the nut block, a pair of first slide rails disposed on the frame, and a first slider that slides the support plates to the first slide rails, and the bracket is fixed on the support plate.

[0019] As a further aspect of the present invention: the bracket includes a pair of support plate connecting plates disposed between a pair of support plates, and a first support plate and a second support plate respectively disposed at both ends of the pair of support plate connecting plates. A set of first sliding grooves is disposed opposite to the inner sides of the first support plate and the second support plate, and a set of second sliding grooves is disposed opposite to the outer sides of the first support plate and the second support plate. A first guide rail that cooperates with the first sliding groove is provided on the belt platform assembly, and a second guide rail that cooperates with the second sliding groove is provided on the material distribution assembly.

[0020] As a further aspect of the present invention: the support frame includes a pair of support plates disposed on the outside of the first support plate and the second support plate, and an upper crossbeam disposed between the pair of support plates. The second lifting mechanism includes a second lifting cylinder disposed on the upper crossbeam, a second slide rod disposed on the support plate, and a second slider disposed at both ends of the crossbeam lifting plate and connected to the second slide rod. The cylinder rod of the second lifting cylinder is connected to the crossbeam lifting plate.

[0021] As a further aspect of the present invention: the belt platform assembly further includes a belt frame and a third rack disposed at the bottom of one side of the belt frame, the first translation mechanism includes a third gear meshing with the third rack, and the belt platform assembly is driven by meshing.

[0022] The beneficial effects of this invention are as follows: This application arranges a material distribution mechanism and several rotary clamping cylinders side by side. Driven by the second translation mechanism, the insert plate of the material distribution mechanism is inserted into the material pile, which lifts up a corner of a part of the material layer to form a gap. Then, the several rotary clamping cylinders sequentially drive the support block to insert into the gap to further lift the material layer, so that one side of the material layer is completely lifted. When the material layer is separated from the material pile, only the part in contact with the insert plate is damaged, reducing the damage range to the material layer. After one side of the material layer is lifted, the first translation mechanism drives the belt platform assembly to move into the gap to support the material layer. After the second translation mechanism moves in the opposite direction and resets, the third lifting mechanism lifts the material distribution assembly again. The drive structure drives the transmission belt to extract the separated material layer from the material pile. The first translation mechanism moves in the opposite direction, driving the material layer on the belt platform assembly to complete the transmission, realizing automatic layered material picking and transmission.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-2 As shown, the present invention is an automatic layered material conveyor, including a frame 1, on which a first lifting mechanism 2 drives a bracket 3 to move up and down. The bracket 3 is provided with a material separating component 4 for layering a material pile 8 and a belt platform component 5 for separating the separated material layers 81 from the material pile 8. Under the drive of a first translation mechanism 6 and a second translation mechanism 7, the belt platform component 5 and the material separating component 4 can move horizontally on the bracket 3.

[0036] Please see Figure 3-4 As shown, in this embodiment, the frame 1 is an L-shaped welded assembly of uprights 12, with a flat base 11, uprights 12 welded to the rear of the base 11, and a triangular plate 13 welded to the connection between the two.

[0037] The front of the column 12 is fixed with a motor bracket 14 by bolts. The first lifting mechanism 2 includes a first lifting motor 21 fixed to the bottom of the motor bracket 14, a lead screw 22 driven by the first lifting motor 21, a nut block 23 threadedly connected to the lead screw 22, a pair of support plates 24 fixed to both ends of the nut block 23, and a pair of first slide rails 25 vertically fixed on the column 12. The inner side of the end of each support plate 24 is fixed with a first slider 26 that slides in cooperation with one of the first slide rails 25. Specifically, the upper support 27 and the lower support 28 of the lead screw are respectively provided on the front of the column 12 and the motor bracket 14. The two ends of the lead screw 22 are rotatably engaged with the upper support 27 and the lower support 28 of the lead screw through bearings. The bottom of the lead screw 22 is also fixedly fitted with a first rotating gear. The first rotating gear is connected to the motor gear on the first lifting motor 21 through a transmission toothed belt. Driven by the first lifting motor 21, the lead screw 22 is rotated, which causes the nut connecting block 23 to move up and down along the lead screw 22. The nut connecting block 23 drives a pair of support plates 24 to slide up and down along the first slide rail 25.

[0038] The bracket 3 is fixed inside a pair of support plates 24, including a pair of support plate connecting plates 31 fixed to the inner walls of the pair of support plates 24, and a first support plate 32 and a second support plate 33 fixed to both ends of the pair of support plate connecting plates 31. The front end of the support plate connecting plate 31 extends out of the support plate 24, so that the first support plate 32 is located outside the pair of support plates 24. The second support plate 33 is located between the two support plates 24. The top surface of the support plate connecting plate 31 is flush with the top surface of the support plate 24. The tops of the first support plate 32 and the second support plate 33 both extend out of the top surface of the support plate connecting plate 31. A pair of first translation sliders 34 are fixed on the inner walls of the first support plate 32 and the second support plate 33, and a pair of second translation sliders 35 are fixed on the outer walls of the first support plate 32 and the second support plate 33. The first translation sliders 34 and the second translation sliders 35 are both located above the support plate connecting plate 31.

[0039] Please see Figure 5 As shown, the belt platform assembly 5 includes a belt frame 51, a transmission belt 52 disposed within the belt frame 51, a drive structure 53 for driving the transmission belt 52 to move, a first translation guide rail 54 disposed on the outer wall of the belt frame 51, and a third rack 55 disposed on the bottom wall of the belt frame 51. The first translation guide rail 54 cooperates with the first translation slider 34. In this embodiment, the drive structure 53 is a rotating roller shaft, which drives the transmission belt 52 to rotate cyclically through its own rotation.

[0040] Please see Figure 3-5 As shown, the first translation mechanism 6 includes a third gear 61 and a first translation motor 62 that drives the third gear 61 to rotate. The first translation motor 62 and the third gear 61 are both fixed inside the second support plate 33. The third gear 61 meshes with the third rack 55. Driven by the first translation motor 62, the third gear 61 drives the third rack 55 to move, causing the first translation guide rail 54 to slide within the first translation slider 34, thereby causing the belt platform assembly 5 to move horizontally as a whole.

[0041] Please see Figure 1 , Figure 4 and Figure 6As shown, the material distribution assembly 4 includes a support frame 41 mounted on the bracket 3, a second lifting mechanism 42 mounted on the support frame 41, a crossbeam lifting plate 43 connected to the second lifting mechanism 42, and a material distribution mechanism 44 and several rotary clamping cylinders 45 arranged side by side on the crossbeam lifting plate 43. The support frame 41 includes a pair of support plates 411 located outside the first support plate 32 and the second support plate 33, and an upper crossbeam 412 fixed between the pair of support plates 411. A second translation guide rail 47 cooperating with the second translation slider 35 is fixed on the inner side wall of each support plate 411, and a fourth rack 48 is fixed on the bottom wall of each support plate 411. The second translation mechanism 7 includes a fourth gear 71 fixed on the outer wall of the first support plate 32 and the second support plate 33 and meshing with the fourth rack 48, a synchronous shaft 72 connecting the two fourth gears 71, an auxiliary gear 73 fixed on the outer wall of the first support plate 32 and meshing with the fourth gear 71, and a second translation motor 74 fixed on the inner wall of the first support plate 32 to drive the auxiliary gear 73 to rotate. The second translation motor 74 drives the auxiliary gear 73 to rotate, and the auxiliary gear 73 drives the fourth gear 71 to rotate, so that the fourth gear 71 drives the second translation guide rail 47 to slide in the second translation slider 35, thereby causing the material distribution assembly 4 to move horizontally as a whole.

[0042] The second lifting mechanism 42 includes a second lifting cylinder 421 fixed on the upper crossbeam 412, a second sliding rod 422 disposed on one end of the support plate 411, and a second slider 423 disposed at both ends of the crossbeam lifting plate 43 and connected to the second sliding rod 422. The cylinder rod of the second lifting cylinder 421 is connected to the crossbeam lifting plate 43. Driven by the second lifting cylinder 421, the crossbeam lifting plate 43 moves up and down along the second sliding rod 422, thereby driving the material distribution mechanism 44 and several rotary clamping cylinders 45 to move up and down.

[0043] Several rotary clamping cylinders 45 together form a rotary clamping cylinder group 45, and a material distribution mechanism 44 is set on one side of the rotary clamping cylinder group 45. The rotary clamping cylinder 45 can rotate between 0 degrees and 90 degrees, and retracts while rotating. After rotating to the correct position, it can also generate a certain retraction stroke. Each rotary clamping cylinder 45 has a duck-foot-shaped support block 46 on its cylinder rod, and the cylinder rod of the rotary clamping cylinder 45 is fixed to the tail of the support block 46, so that the rotary clamping cylinder 45 drives the support block 46 to rotate 90 degrees and drives the support block 46 to rise or fall.

[0044] In one specific embodiment of this application, the material distribution mechanism 44 includes an insert plate 4401 and a third lifting mechanism 442 that drives the insert plate 4401 to move up and down. The second translation motor 74 drives the material distribution mechanism 44 to move as a whole toward the material pile 8 so that the insert plate 4401 is inserted into the material pile 8 to form different material layers 81. The third lifting mechanism 442 drives the insert plate 4401 to move upward to a predetermined height, so that gaps 82 are generated between the material layers 81.

[0045] Please see Figure 7-8 As shown, in this embodiment, the insert plate 4401 includes a main insert plate 44011 and a secondary insert plate 44012. The material distribution assembly 4 also includes a support structure 441, a fixing frame 443, a main insert plate fixing plate 444, a first telescopic guide rail structure 445, a first rack 446, a second rack 447, a rotating shaft 448, a first gear 449, and a second gear 4400.

[0046] The support structure 441 includes a back plate 4411 and a cylinder fixing plate 4412 disposed at the top of the back plate 4411. The third lifting mechanism 442 includes a third lifting cylinder 4421 fixed on the cylinder fixing plate 4412, a third lifting guide rail 4422 fixed on the back plate 4411, and a lifting slider 4423 fixed on the fixing frame 443. The cylinder rod of the third lifting cylinder 4421 extends through the cylinder fixing plate 4412 to one side of the back plate 4411. The third lifting guide rail 4422 is fixed on the back plate 4411. The fixing frame 443 is connected to the cylinder rod of the third lifting cylinder 4421 through a connector 4403. The third lifting cylinder 4421 drives the fixing frame 443 to move up and down along the third lifting guide rail 4422.

[0047] The mounting bracket 443 includes a slide plate 4431, a left support plate 4432 and a right support plate 4433 disposed on both sides of the slide plate 4431, and a stop plate 4434 fixed to the bottom of the left support plate 4432. The slide plate 4431 is disposed on one side of the back plate 4411, and the lifting slider 4423 is fixed to the back of the slide plate 4431 and cooperates with the third lifting guide rail 4422. The connector 4403 is fixed to the upper part of the front of the slide plate 4431, and the left support plate 4432 and the right support plate 4433 are fixed to the lower sides of the front of the slide plate 4431. The auxiliary insert plate 44012 is fixed to the bottom front end of the stop plate 1034, and the front end of the auxiliary insert plate 44012 extends out of the stop plate 1034. The left support plate 4432 and the right support plate 4433 are provided with concentric bearing holes, and bearings are installed in the bearing holes. The rotating shaft 448 passes through the bearings and is rotatably connected to the left support plate 4432 and the right support plate 4433. The first gear 449 and the second gear 4400 are respectively fixed at both ends of the rotating shaft 448 and rotate synchronously. The first gear 449 is located between the left support plate 4432 and the right support plate 4433, and the second gear 4400 is located outside the right support plate 4433. The main insert plate fixing plate 444 is mounted on the inner wall of the right support plate 4433 via the first telescopic guide rail structure 445. The main insert plate fixing plate 444 is L-shaped, with its vertical portion located between the left support plate 4432 and the right support plate 4433. The horizontal portion of the main insert plate fixing plate 444 is located below the stop plate 4434, which has a stop protrusion 44341 located between the horizontal portion of the main insert plate fixing plate 444 and the auxiliary insert plate 44012. The first telescopic guide rail structure 445 has a first telescopic slider fixed to the outer wall of the vertical portion of the main insert plate fixing plate 444 and a first telescopic slide rail fixed to the inner side of the right support plate 4433. The first telescopic slider and the first telescopic slide rail are slidably engaged. The first rack 446 is fixed to the top surface of the horizontal portion of the main insert plate fixing plate 444. The first rack 446 meshes with the first gear 449. The main insert plate 44011 is fixed to the bottom front end of the horizontal portion of the main insert plate fixing plate 444. A recessed step is provided at the bottom front end of the horizontal portion of the main insert plate fixing plate 444. The rear end of the main insert plate 44011 is fixed within the step, making the bottom surface of the main insert plate 44011 flush with the bottom surface of the horizontal portion of the main insert plate fixing plate 444. The rear end face of the main insert plate 44011 contacts the step surface. The front end of the main insert plate extends below the auxiliary insert plate 44012, and the top surface of the main insert plate 44011 is in contact with the bottom surface of the auxiliary insert plate 44012. The length of the main insert plate 44011 is greater than the length of the auxiliary insert plate 44012.

[0048] The second rack 447 is connected to the back plate 4411 via a buffer member 4404. The buffer member 4404 includes an upper guide rod support 44041 mounted on the back plate 4411, a guide rod 44042 passing through a mounting hole in the upper guide rod support 44041, a limiting member 44043 fixedly mounted on the top of the guide rod 44042, a lower guide rod support 44044 fixedly mounted on the bottom of the guide rod 44042, and a buffer spring 44045 sleeved on the guide rod 44042 and located between the upper guide rod support 44041 and the lower guide rod support 44044. The guide rod 44042 is clearance-fitted with the mounting hole. The limiting member 44043 is threaded to the top of the guide rod 44042 to prevent the guide rod 44042 from sliding down and disengaging from the mounting hole in the upper guide rod support 44041. The second rack 447 is fixed at the bottom end of the guide rod lower support 44044 and located on one side of the slide plate 4431. The second rack 447 meshes with the second gear 4400. A lifting guide rail structure 44046 is provided between the guide rod lower support 44044 and the slide plate 4431. The lifting guide rail structure 44046 has a slider fixed on the guide rod lower support 44044 and a guide rail fixed on the slide plate 4431 that cooperates with the slider. Through the setting of the lifting guide rail structure 44046, the guide rod lower support 44044 and the slide plate 4431 are slidably connected.

[0049] The working principle of the automatic layered material handling conveyor of the present invention will be described below:

[0050] Please see Figure 1 , Figure 4-10 As shown, the first lifting motor 21 drives the belt platform assembly 5 and the material distribution assembly 4 to a specified height via the drive screw 22. The second translation motor 74 drives the material distribution assembly 4 to move towards the material pile 8, so that the auxiliary insert plate 44012 first inserts into the material pile 8 to open the material layer 81 and form a gap interval 82 (see...). Figure 9The third lifting cylinder 4421 drives the auxiliary insert plate 44012 to rise. At the beginning of the rise, the second rack 447 is stationary under the action of the buffer spring 44045. The second gear 4400 rolls upward along the second rack 447, driving the first gear 449 and the second gear 4400 to rotate synchronously. This causes the first gear 449 to drive the first rack 446 to move forward, and simultaneously drive the front end of the main insert plate 44011 to extend out of the front end of the auxiliary insert plate 44012 and insert into the gap interval 82. This achieves the simultaneous upward movement of the main insert plate 44011 driven by the third lifting cylinder 4421 and the horizontal extension of the main insert plate 44011. When the main insert plate fixing plate 444 contacts the stop protrusion 44341 and is stopped, the main insert plate 44011 no longer extends. At this time, the second gear 4400 that drives the extension of the main insert plate 44011 can no longer roll on the second rack 447. Thus, the second gear 4400 and the second rack 447 are relatively stationary at the meshing point and rise together with the third lifting cylinder 4421. At this time, the buffer spring 44045 is compressed through the lower support 44044 of the guide rod, so that after the third lifting cylinder 4421 drives the main insert plate 44011 to rise to a certain height, it can only drive the main insert plate 44011 to rise and stop the extension of the main insert plate 44011.

[0051] After the main insert plate 44011 and the auxiliary insert plate 44012 are raised to their predetermined positions, the rotary clamping cylinder 45 closest to the material distribution mechanism 44 rotates and retracts, causing the support block 46 to rotate 90 degrees into the gap section 82 and reliably support the bottom of the material layer 81. During the rotation of the support block 46 into position, the rotary clamping cylinder 45 retracts a certain distance and drives the support block 46 to further lift the material layer 81. When the operation of one rotary clamping cylinder 45 is completed, the adjacent rotary clamping cylinder 45 repeats the above-mentioned action of the rotary clamping cylinder 45. Through the cooperation of the material distribution mechanism 44 and several rotary clamping cylinders 45, one side of the material layer 81 is completely lifted. Subsequently, the first translation motor 62 drives the belt platform assembly 5 to insert into the gap section 82 from below the main insert plate 440440, supporting and holding the bottom of one side of the material layer 81. After the second translation motor 74 drives the material distribution assembly 4 to move in the reverse direction and reset, the third lifting cylinder 4421 lifts the material distribution mechanism 44 and the rotating cylinder 45, thereby forming a gap channel between the support block 46 and the conveyor belt 52, allowing the material layer 81 to pass through. The drive structure 53 is activated, driving the conveyor belt 52 to rotate. Under the action of friction, the separated material layer 81 is completely dragged onto the conveyor belt 52. The first translation motor 62 drives in the reverse direction, causing the belt platform assembly 5 to remove the material layer 81 and then transport it in the reverse direction. After the belt platform assembly 5 transports the material layer 81 to the reverse position, the first lifting motor 21 starts in reverse and drives the support 3 and the belt platform assembly 5 to descend to the starting position along with the picked-up material layer 81 through the first lifting mechanism 2.

[0052] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

The material distribution mechanism includes an insert plate and a third lifting mechanism that drives the insert plate to move up and down. After the second translation mechanism drives the insert plate to insert into the material pile, the third lifting mechanism drives the insert plate to move upward, creating a gap between the material layers. Several of the rotary clamping cylinders sequentially drive the support block to insert into the gap and lift it, so that one side of the separated material layer is completely lifted. The first translation mechanism drives the belt platform assembly to move into the gap and support the material layer. After the second translation mechanism moves in the opposite direction and resets, the second lifting mechanism lifts the material distribution mechanism and the rotary clamping cylinders again. The transmission belt rotates to move the separated material layer onto the transmission belt. The insert plate includes a main insert plate and a secondary insert plate. The material distribution assembly also includes a support structure, a fixing frame, a main insert plate fixing plate, a first telescopic guide rail structure, a first rack, a second rack, a rotating shaft, a first gear, and a second gear. The third lifting mechanism is mounted on the support structure to drive the fixing frame to move up and down. The secondary insert plate is fixed to the bottom of the fixing frame. The main insert plate is fixed to the main insert plate fixing plate and is located at the bottom of the secondary insert plate. The main insert plate fixing plate is slidably connected to the fixing frame through the first telescopic guide rail structure. The first rack is mounted on the main insert plate fixing plate, and the second rack is located on one side of the fixing frame. The rotating shaft is rotatably connected to the fixing frame through a bearing. The first gear and the second gear are both fixed on the rotating shaft.
