Description

Technical Field

[0001] This invention belongs to the field of saw chain assembly technology, and particularly relates to an automatic saw chain assembly machine. Background Technology

[0002] A saw chain consists of a drive plate, saw blade, and connecting plate connected in series by a chain shaft. Therefore, during assembly, the drive plate, saw blade, connecting plate, and rivet post need to be connected in series and the rivet posts at both ends need to be riveted.

[0003] Currently, there are various automated saw chain assembly devices on the market, such as the Chinese invention patent with publication number CN109822342B, entitled "A Fully Automatic Saw Chain Production Equipment," which discloses a fully automatic saw chain production device. This fully automatic saw chain production equipment includes a frame and a lower saw block assembly device, a connecting block assembly device, and a fastening device mounted on the frame. The lower saw block assembly device assembles components into lower saw blocks and feeds the assembled semi-finished products to the fastening device. The connecting block assembly device assembles components into connecting blocks and feeds the assembled semi-finished products to the fastening device. The two semi-finished products are arranged in an orderly manner, and the fastening device assembles and presses together other components.

[0004] However, during the assembly of saw blocks or connecting blocks, the aforementioned patented products often encounter the problem that the rivet cannot be properly inserted into the connecting hole of the saw blade or connecting piece (the main reason being that some saw blades or connecting pieces may have burrs in the hole or mismatched hole diameter during processing or arrangement). This leads to the failure of the rivet and the saw blade or connecting piece to connect, resulting in material jamming, which in turn halts the automatic assembly process and affects the overall assembly efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic saw chain assembly machine, which solves the technical problem of material jamming causing assembly process stagnation and affecting overall assembly efficiency when existing automatic saw chain assembly machines encounter the above-mentioned technical problems by setting material release and unrelease components on each feeding component.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automatic saw chain assembly machine, including a frame and a fastening device, a lower saw block assembly device and a connecting block assembly device installed on the frame, wherein the connecting block assembly device includes an assembly conveyor table; A connecting piece feeding assembly, the connecting piece feeding assembly including a feeding mechanism for separating connecting pieces and a picking mechanism for gripping individual connecting pieces; A rivet feeding assembly is used to transport rivets to an assembly conveyor table; A riveting assembly for riveting a connecting piece and a rivet post; A material feeding / returning assembly, which controls the material feeding mechanism to feed or return material by sensing the positional relationship between the material feeding mechanism and the assembly conveyor; A material unloading mechanism is movably provided on one side of the material taking mechanism. The material unloading mechanism unloads the connecting piece that cannot be installed on the rivet column during the material return process of the material taking mechanism.

[0007] Preferably, the feeding and unloading assembly includes a feeding mechanism and an unloading mechanism. The feeding mechanism includes a sensing end fixed on one side of the connecting seat and a sensing switch installed on the assembly conveyor. The electromagnet remains energized during the material handling process. When the electromagnet fastens the connecting piece onto the rivet post, the sensing end and the sensing switch correspond vertically and trigger the sensing switch, causing the electromagnet to be de-energized to complete the feeding of the connecting piece.

[0008] Preferably, the connecting seat is provided with a drive groove, and a micro switch is provided in the drive groove. The electromagnet moves up and down in the drive groove. During the process of the electromagnet driving the connecting piece downward and assembling the rivet, when the connecting piece is blocked and cannot reach the designated position, the electromagnet will be resisted and retract, triggering the micro switch. The micro switch causes the material picking cylinder to return material upward and simultaneously drives the unloading mechanism to run.

[0009] Preferably, the unloading mechanism includes a plurality of unloading cylinders mounted on the drive frame. The drive end of the unloading cylinder is provided with a thumb cylinder. The clamping part of the thumb cylinder and the parts protruding from the electromagnet on both sides of the connecting piece are correspondingly arranged. The micro switch is used to control the drive end of the unloading cylinder to push outward, and at the same time control the thumb cylinder to clamp the connecting piece during the return process to complete the unloading.

[0010] Preferably, the assembly conveyor is rotatably mounted on the frame via a transmission component. The assembly conveyor has several blind holes around its circumference. The rivet feeding component includes a vibrating plate, and a guide tube is provided at the discharge end of the vibrating plate. The rivet feeding component conveys the rivet through the guide tube to the blind holes by vibration.

[0011] Preferably, the connecting piece feeding assembly further includes a conveying assembly, a flow guiding assembly, and a feeding assembly. The semi-finished product riveted by the riveting assembly is conveyed to the flow guiding assembly by the conveying mechanism. The flow guiding assembly is used to convey the riveted connecting block and reverse its direction. The feeding assembly is connected to the discharge end of the flow guiding assembly and clamps and transports the aligned connecting block to the fastening device.

[0012] Preferably, the fastening device includes a worktable, a lower support plate, an upper clamping plate, clamping blocks, a suspension seat assembly, a transmission plate loading mechanism, an upper connecting piece loading mechanism, an upper saw blade loading mechanism, and a riveting machine; the worktable is fixedly mounted on the frame, and the lower support plate is located below the worktable; the clamping blocks are fixedly mounted side by side on the upper clamping plate, the spacing between the clamping blocks corresponding to the ridges of the lower support plate, and the connecting piece and the upper saw blade are precisely assembled between the two clamping blocks; the lower support plate and the upper clamping plate are independently driven by two orthogonal cylinders, and the travel trajectory is a rectangular loop; the suspension seat assembly is fixedly mounted on the frame; the transmission plate loading mechanism, the upper connecting piece loading mechanism, and the upper saw blade loading mechanism are located on the side of the worktable and are sequentially connected, corresponding to the wire rope strings above them; the riveting machine is connected to the upper saw blade loading mechanism.

[0013] Preferably, the flow guiding assembly includes a vibrating motor, a transfer rail, a baffle plate, and a rotating track; the transfer rail is mounted on the vibrating motor, the baffle plate is vertically mounted on the transfer rail and located above the transfer rail, the rotating track connects the two ends of the transfer rail, and the rotating track is twisted 180 degrees for a natural transition; the cross-sectional shape of the inner cavity of the rotating track matches the structure of the lower saw block; the baffle plate and the transfer rail together restrict the lower saw block.

[0014] Preferably, the lower saw block assembly device, the transmission plate feeding mechanism, the upper connecting plate feeding mechanism, and the upper saw blade feeding mechanism are all the same as the connecting plate feeding assembly, and all are equipped with a material release and unloading assembly and a material unloading mechanism.

[0015] Through the above technical solution, compared with the prior art, the present invention has the following beneficial effects: By setting a feeding and unfeeding assembly at the feeding mechanism, the feeding and unfeeding assembly includes a feeding mechanism and an unfeeding mechanism. The feeding mechanism is used to control the opening and closing of the feeding mechanism. Specifically, after the feeding mechanism picks up the connecting piece from the feeding mechanism, the feeding mechanism will drive the connecting piece to move downwards to install it on the rivet on the assembly conveyor table. During this process, the feeding mechanism drives the connecting piece to move downwards continuously, gradually shortening the distance between the connecting piece and the rivet. When the connecting piece is pushed to the designated position (i.e., the rivet passes through the connecting hole on the connecting piece, and the connecting piece is fastened on it), the sensing end of the feeding mechanism located on the assembly conveyor table will receive a signal from the feeding mechanism, thereby triggering the feeding mechanism to release the restriction on the connecting piece, thus completing the feeding process. Afterwards, the feeding mechanism returns to perform the next round of feeding process; unfeeding... The mechanism controls the material handling mechanism to retract the problematic workpiece and re-grab a new workpiece, while simultaneously controlling the unloading mechanism to remove the problematic workpiece during the retraction process. Specifically, when the material handling mechanism moves the connecting piece downwards to install it onto the rivet, if the connecting piece is a problematic workpiece (i.e., the diameter of the connecting hole on the connecting piece does not match the diameter of the rivet, or there are burrs in the connecting hole on the connecting piece, in which case the rivet cannot pass through the connecting hole, causing the connecting piece and the rivet to fail to align), the material handling mechanism will encounter resistance and will be unable to continue moving downwards to complete the alignment of the connecting piece and the rivet. At this point, the material removal mechanism will be activated. After the material removal mechanism is activated, it simultaneously triggers the return motion of the material handling mechanism and the unloading motion of the unloading mechanism, so that during the return motion of the material handling mechanism, the unloading mechanism removes the problematic workpiece located on the material handling mechanism and completes the unloading process. The material handling mechanism then re-grabs the material and re-grabs a new connecting piece to align with the rivet.

[0016] In summary, this invention, by setting up feeding and unloading components on each feeding mechanism, ensures that the feeding mechanism only feeds material when the rivet column and each workpiece are successfully connected. When the rivet column and each workpiece fail to connect, the unloading mechanism and the unloading mechanism are triggered. By retrieving and unloading the problematic workpiece, the faulty workpiece is removed and re-fetched, and then reassembled until the feeding mechanism is triggered again to successfully connect the rivet column and each workpiece.

[0017] The above method effectively improves the assembly efficiency of the saw chain and avoids the technical problem of material jamming during operation, which can cause the entire assembly process to stop. Attached Figure Description

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0023] like Figure 1-9 The diagram shows an automatic saw chain assembly machine, comprising a frame and a fastening device 1, a lower saw block assembly device 2, and a connecting block assembly device 3 mounted on the frame. The lower saw block assembly device 2 assembles components (lower saw blade and rivet) into lower saw blocks and feeds the assembled semi-finished products to the fastening device 1. The connecting block assembly device 3 assembles components (connecting pieces and rivets) into connecting blocks and feeds the assembled semi-finished products to the fastening device 3. The two semi-finished products are arranged in an orderly manner, and the fastening device 3 assembles and presses other components together. The frame includes a main frame and auxiliary frames located at one end of the main frame and arranged on both sides. The lower saw block assembly device 2 and the connecting block assembly device 3 are respectively mounted on their respective auxiliary frames.

[0024] The connecting block assembly device 3 includes an assembly conveyor 301, which includes a turntable and a drive motor for driving rotation. The assembly conveyor 301 is installed at the center of the sub-frame. The rotation of the assembly conveyor 301 causes the rivet 101, which is first conveyed to it, to pass through the rivet feeding assembly 304 and the riveting assembly 305 in sequence, and then be conveyed to the fastening device 1.

[0025] The connecting piece feeding assembly 303 includes a feeding mechanism 307 for separating the connecting pieces 100 and a picking mechanism 308 for gripping a single connecting piece 100. In this embodiment, the feeding mechanism 307 is a vibrating plate, and a vibrating feeder is connected to the outlet of the vibrating plate. The vibrating feeder arranges the connecting pieces 100 individually and orderly and transports them to the picking mechanism 308.

[0026] The rivet column feeding assembly 304 is used to transport the rivet column 101 to the assembly conveyor table 301. The rivet column feeding assembly 305 feeds the rivet column 101 by vibration. The rivet column 101 is cylindrical and has a circular guide pipe at the discharge end. The rivet column 101 is transported to the assembly conveyor table 301. The rivet column feeding assembly 304 includes a vibrating plate and a double row of straight vibrators located at the discharge port of the vibrating plate. The guide pipe between the double row of straight vibrators and the assembly conveyor table 301 can transport the rivet column 101 to the assembly conveyor table 301 in groups of two to complete the feeding action of the rivet column 101.

[0027] Riveting assembly 305, riveting assembly 305 is a riveting machine, riveting assembly 305 is used to rivet connecting piece 100 and rivet post 101 to form a semi-finished connecting block; The material feeding and unloading assembly controls the material feeding mechanism 308 to feed or return materials by sensing the positional relationship between the material feeding mechanism 308 and the assembly conveyor 301. A material handling mechanism 4 is movably provided on one side of the material handling mechanism 308. The material handling mechanism 4 unloads the connecting piece 100 that cannot be installed on the rivet 101 during the material return process of the material handling mechanism 308.

[0028] like Figure 4-9As shown, a feeding / unfeeding assembly is provided at the feeding mechanism 308. This assembly includes a feeding mechanism and an unfeeding mechanism. The feeding mechanism controls the opening and closing of the feeding mechanism 308. Specifically, after the feeding mechanism 308 picks up the connecting piece 100 from the loading mechanism 307, it moves the connecting piece 100 downwards to install it onto the rivet 101 located on the assembly conveyor table. During this process, the feeding mechanism 308 continuously moves the connecting piece 100 downwards, causing the connecting piece 100 and the rivet 101 to... The distance between 01 and 01 gradually shortens. When the connecting piece 100 is pushed to the designated position (i.e., the rivet 101 passes through the connecting hole on the connecting piece 100, and the connecting piece 100 is fastened on it), the sensing end of the feeding mechanism located on the assembly conveyor will receive a signal from the picking mechanism 308, thereby triggering the feeding mechanism to release the restriction on the connecting piece 100, thus completing the feeding process. Afterwards, the picking mechanism 308 returns to start the next round of feeding process; the unloading mechanism is used to control the picking mechanism 308 to drive The problematic workpiece is returned to the machine and a new workpiece is picked up. Simultaneously, the unloading mechanism removes the problematic workpiece during the return process. Specifically, during the process where the picking mechanism 308 moves the connecting piece 100 downwards to install it onto the rivet 101, if the connecting piece 100 is a problematic workpiece (i.e., the diameter of the connecting hole on the connecting piece 100 does not match the diameter of the rivet 101, or the connecting hole on the connecting piece 100 has burrs), the rivet 101 cannot pass through the connecting hole, resulting in the connecting piece 100 and the rivet 101 failing to connect. If the material handling mechanism 308 encounters resistance and cannot continue to move down to complete the docking of the connecting piece 100 and the rivet 101, the material handling mechanism 308 will be activated. After the material handling mechanism is activated, the return motion of the material handling mechanism 308 and the unloading motion of the unloading mechanism are triggered simultaneously. During the return motion of the material handling mechanism 308, the unloading mechanism removes the problematic workpiece located on the material handling mechanism 308 and completes the unloading process. The material handling mechanism 308 then picks up the material again and grabs a new connecting piece 100 and rivet 101 for docking.

[0029] like Figure 4-8As shown: The material handling mechanism 308 includes a longitudinally arranged material handling cylinder 5. A connecting seat 6 is fixed on the drive end of the material handling cylinder 5. An electromagnet 7 is movably arranged inside the connecting seat 6. The material handling cylinder 5 is mounted on a drive frame 8. The drive frame 8 drives the material handling cylinder 5 to move laterally to pick up the connecting piece 100 at the material feeding assembly 303. In this embodiment, the drive frame 8 is installed on one side of the assembly conveyor table 301 and is located downstream of the material feeding mechanism 307. The drive frame 8 includes a stand and a linear drive module. A slider is provided on the bottom surface of the stand, and a slide rail is provided on the sub-frame. The stand is driven by a push cylinder and a slider. The slide rail slides on the upper surface of the sub-frame. By controlling its front and rear positions, it can grasp the workpiece more quickly and from multiple angles and place it on the assembly conveyor 301 to dock with the rivet column 101. The linear drive module is installed above the stand. The picking cylinder 5 is set on the movable end of the linear drive module, so that the picking cylinder 5 can move laterally along the extension of the linear drive module to be in the relative position of the loading mechanism 307 and the rivet column 101 assembly. The driving end of the picking cylinder 5 is equipped with a connecting seat 6. The connecting seat 6 is used to fix the electromagnet 7 and also to trigger the ejection mechanism and the unloading mechanism.

[0030] In addition, the electromagnet is energized and de-energized according to the positional relationship between the material feeding and unfeeding assembly and the assembly conveyor 301. Specifically, when the material picking mechanism 308 moves to the feeding mechanism 307, the electromagnet will attract the connecting piece 100. Then, the material picking mechanism 308 drives the connecting piece 100 to move above the rivet post 101 and dock. When the docking is successful, the electromagnet is de-energized due to the influence of the material feeding mechanism. At this time, the connecting piece 100 located on it will be lowered to complete the docking with the rivet post 101.

[0031] like Figure 4-9 As shown: The material feeding and unfeeding assembly includes a feeding mechanism and an unfeeding mechanism. The feeding mechanism includes a sensing end 9 fixed to one side of the connecting seat 6 and a sensing switch 10 installed on the assembly conveyor table 301. The electromagnet 7 remains energized during the material feeding process. When the electromagnet 7 fastens the connecting piece 100 onto the rivet post 101, the sensing end 9 and the sensing switch 10 align vertically and trigger the sensing switch 10, causing the electromagnet 7 to be de-energized to complete the feeding of the connecting piece 100. Multiple sensing switches 10 can be configured, i.e., sensing switches 10 can be installed at fixed positions on the rivet post 101 to achieve rapid triggering and precise control. Alternatively, they can be installed individually below the feeding mechanism 308, controlling the opening and closing of the electromagnet 7 by sensing the sensing end 9 each time.

[0032] like Figure 9As shown: The connecting seat 6 is provided with a drive groove 11, and a micro switch 12 is provided in the drive groove 11. The electromagnet 7 moves up and down in the drive groove 11. During the process of the electromagnet 7 driving the connecting piece 100 downward and assembling it with the rivet 101, when the connecting piece 100 is blocked and cannot reach the designated position, the electromagnet 7 will be resisted and retract, triggering the micro switch 12. The micro switch 12 causes the picking cylinder 5 to return material upward and simultaneously drives the unloading mechanism 4 to run. When the electromagnet 7 moves downward normally, the electromagnet 7 is abutted by the limiting part in the drive groove 11 or at the opening, thereby preventing it from falling out of the drive groove 11. When the connecting piece 100 on the electromagnet 7 cannot be fitted onto the rivet 101, the rivet 101 will give the electromagnet 7 an upward force, causing the electromagnet 7 to move in the reverse direction in the drive groove 11 until it triggers the micro switch 12 located on the top wall of the drive groove 11, thereby causing the picking cylinder 5 to return material and triggering the unloading mechanism 4 to remove the connecting piece 100 located on the electromagnet 7.

[0033] like Figure 3-8 As shown: The unloading mechanism 4 includes several unloading cylinders 13 mounted on the drive frame 8. Thumb cylinders 14 are provided on the drive end of each unloading cylinder 13. The clamping part of the thumb cylinder 14 and the portions of the connecting piece 100 protruding from the electromagnet 7 on both sides are correspondingly arranged. The micro switch 12 is used to control the drive end of the unloading cylinder 13 to push outwards, and simultaneously control the thumb cylinder 14 to clamp the connecting piece 100 during the material return process to complete the unloading. In this embodiment, when the unloading mechanism 4 is not activated, it retracts into the placement slot opened on the stand. Generally, two sets of unloading cylinders 13 are provided for greater stability. The connecting plate 100 is held in place on both sides. When the unloading mechanism 4 is triggered, the drive end of the unloading cylinder 13 first extends to one side of the connecting plate 100 and opens the clamping part of the thumb cylinder 14. When the clamping part moves to the upper and lower positions of the connecting plate 100, the thumb cylinder 14 is clamped again and the drive end of the unloading cylinder 13 is pushed back. During this process, the connecting plate 100 is placed in front of the drive frame 8 and passes through the waste box 24. When the thumb cylinder 14 moves above the waste box, the connecting plate 100 on the thumb cylinder 14 will fall into the waste box 24 to facilitate the recycling and reuse of waste.

[0034] like Figure 1-3 As shown: The assembly conveyor 301 is rotatably mounted on the frame via a transmission component. The assembly conveyor 301 has several blind holes 306 around its circumference. The rivet feeding component 304 includes a vibrating plate. The discharge end of the vibrating plate is provided with a guide tube. The rivet feeding component 304 conveys the rivet 101 to the blind holes 306 via the guide tube through vibration.

[0035] like Figure 1As shown: The connecting piece feeding assembly 303 also includes a conveying assembly 15, a flow guiding assembly 16 and a feeding assembly 17. The semi-finished product riveted by the riveting assembly 305 is conveyed by the conveying mechanism 15 to the flow guiding assembly 16. The flow guiding assembly 16 is used to convey the riveted connecting block and reverse its direction. The feeding assembly 17 is connected to the discharge end of the flow guiding assembly 16 and clamps and transports the aligned connecting block into the fastening device 3.

[0036] Furthermore, the lower saw blade assembly device 2 in this embodiment is existing technology, including a rotating fixture assembly, a lower saw blade feeding mechanism, a riveting column feeding assembly, a riveting assembly, a conveying mechanism, a flow guiding assembly, and a feeding mechanism mounted on the auxiliary frame. The lower saw blade feeding mechanism includes a circular vibrator, a linear vibrator, a horizontal push cylinder, a vertical push cylinder, a fork plate, a guide block, a vertical push component, a horizontal pull component, a storage trough, a push cylinder, a push block, a pressing cylinder, and a fixed base. The linear vibrator and the circular vibrator are connected to achieve orderly discharge of the lower saw blade. The fork plate is located on the side of the discharge track of the linear vibrator. The fork plate is connected to the telescopic end of the vertical push cylinder, and the telescopic end of the horizontal push cylinder is connected to the vertical push cylinder. The horizontal push cylinder and the vertical push cylinder are arranged perpendicularly. The height of the fork plate is flush with the discharge track of the linear vibrator. Three rectangular slots are provided on the fork plate. The outer contour of the rectangular groove corresponds to the lower saw blade mechanism; the guide block connects to the discharge end of the linear vibrator, the guide block has grooves, and the discharge end has a through hole; the vertical push component includes a vertical push cylinder and a lifting push block installed on the telescopic end of the vertical push cylinder; the lifting push block fits in the through hole, and the upper end of the lifting push block has the same grooves as the surface of the guide block; the fixed base is fixedly installed on the frame, the storage trough is vertically installed on the fixed base, and the storage trough has a vertical through groove, the contour of which matches the contour of the lower saw blade; the horizontal pull component is located above the storage trough, including a horizontal pull cylinder and a horizontal pull block, the horizontal pull block is positioned corresponding to the lifting push block, and pulls the raised lower saw blade horizontally to the top of the storage trough and into the storage trough; the push cylinder is horizontally installed on the fixed base, the push block is installed on the telescopic end of the push cylinder, and the push block is located below the storage trough; the pressure cylinder is vertically installed on the back side of the storage trough, corresponding to the farthest position of the push block.

[0037] When the saw blade feeding mechanism is working, the lower saw blades are discharged in an orderly manner after vibration. The fork plate catches the three lower saw blades. The lower saw blades are fed step by step by the horizontal push cylinder and the vertical push cylinder. The lower saw blades that reach the end are lifted by the vertical push component. After being lifted, the lower saw blades are sent to the storage trough by the horizontal pull component. The lower saw blades are stacked in the storage trough. The lower saw blade at the bottom is pushed out by the push block. Finally, the pressing cylinder presses the individual lower saw blades onto the two rivets 101 in the rotating fixture assembly.

[0038] like Figure 1As shown: The fastening device 3 includes a worktable, a lower support plate, an upper clamping plate, clamping blocks, a suspension seat assembly, a transmission plate loading mechanism 20, an upper connecting piece loading mechanism 21, an upper saw blade loading mechanism 22, and a riveting machine 23; the worktable is fixedly mounted on the frame, and the lower support plate is located below the worktable; the clamping blocks are fixedly mounted side by side on the upper clamping plate, and the spacing between the clamping blocks corresponds to the convex patterns on the lower support plate, with the connecting piece and the upper saw blade precisely assembled between the two clamping blocks; the lower support plate and the upper clamping plate are independently driven by two orthogonal cylinders, and their travel trajectory is a rectangular loop; the suspension seat assembly is fixedly mounted on the frame; the transmission plate loading mechanism 20, the upper connecting piece loading mechanism 21, and the upper saw blade loading mechanism 22 are located on the side of the worktable and are sequentially connected, corresponding to the steel wire rope strings above them; the riveting machine 23 is connected to the upper saw blade loading mechanism 22.

[0039] The transmission plate loading mechanism 20 includes a base, a material trough plate, a feeding cylinder, a separating plate, a pressing cylinder, and a pressing block. The material trough plate is vertically mounted on the base and has vertical grooves corresponding to the shape of the transmission plate. The grooves have notches on the sides for observation and cleaning. The separating plate is connected to the telescopic end of the feeding cylinder and is located below the material trough plate. The feeding cylinder is horizontally fixed on the base, and the pressing cylinder is fixed on the back side of the material trough plate. The pressing block is installed on the telescopic end of the pressing cylinder. During operation, the transmission plates are stacked in the material trough plate. The feeding cylinder pushes the separating plate out, pushing the bottommost transmission plate out to the side. Then, the pressing cylinder presses the pressing block down onto the lower transmission plate, embedding it into the lower saw blade and connecting block. The upper connecting plate loading mechanism 21, the upper saw blade loading mechanism 22, and the transmission plate loading mechanism 20 have the same mechanism, differing only in the shape of the inner cavity of the material trough plate. All are used for loading plate-shaped parts.
