Description

Technical Field

[0001] This application relates to the field of shaft parts machining, and in particular to an automatic straightening machine. Background Technology

[0002] Shafts are commonly used in transmission mechanisms and are among the most common parts in machinery and equipment. Currently, shafts are also widely used in electronic products, such as mobile phones, thus the precision requirements for shafts are increasing with societal development. Because shafts are generally long and slender, they are prone to bending deformation during production, especially for parts requiring external thread machining. This results in shafts with large circular runout parameters, making it difficult to meet practical application requirements. Summary of the Invention

[0003] To address the technical problem of large circular runout parameters in shaft-type parts, this application provides an automatic straightening machine.

[0004] This application provides an automatic straightening machine, which adopts the following technical solution: An automatic straightening machine includes a rotating mechanism, a detection module, and a straightening mechanism. The rotating mechanism includes a support base, a pressing drive source, a rotation drive source, and a friction wheel. The support base has a receiving groove for accommodating the end of a shaft-like part. The pressing drive source drives the friction wheel to press against the circumferential sidewall of the shaft-like part placed in the receiving groove. The rotation drive source drives the friction wheel to rotate. The detection module detects the circular runout of the shaft-like part. The straightening mechanism includes a straightening drive source and a top block. The straightening drive source drives the top block to press against the circumferential sidewall of the shaft-like part. The direction in which the straightening drive source drives the top block to move is the same as the direction in which the pressing drive source drives the friction wheel to move.

[0005] By adopting the above technical solution, a clamping drive source presses the shaft-like parts onto the support base, and then a rotation drive source drives the friction wheel to rotate. The friction wheel drives the shaft-like parts to rotate through friction. During the rotation of the shaft-like parts, the detection module detects the circular runout of the shaft-like parts. If the circular runout exceeds the acceptable range, the straightening drive source drives the top block to press the shaft-like parts, straightening them. This achieves full automation of the "detection-straightening" process, resulting in high precision of the processed shaft-like parts, saving manpower, and improving processing efficiency. The straightening drive direction is consistent with the clamping direction of the friction wheel, avoiding part misalignment during the straightening process and improving straightening accuracy. The friction wheel clamps the end of the part and drives its rotation, ensuring stable rotation of the part during detection and reducing measurement errors.

[0006] Optionally, multiple friction wheels are provided, at least one of which is made of an elastic material and is used to press shaft-like parts onto the support.

[0007] By adopting the above technical solution, compared to using a single friction wheel to drive the rotation of shaft parts, using multiple friction wheels to drive the rotation of shaft parts increases the contact area between the friction wheels and the shaft parts, thereby improving the driving force. The elastic friction wheels provide cushioning when pressing against the parts, preventing damage to the part surface from hard contact. Elastic deformation increases the contact area with the ends of the parts, enhancing friction and preventing rotational slippage or positional misalignment.

[0008] Optionally, the rotating mechanism further includes a plurality of driven wheels rotatably mounted on the support base, and the receiving groove is formed by two adjacent driven wheels, the driven wheels being used to roll against the shaft-like parts.

[0009] By adopting the above technical solution, the driven wheels support the shaft-like parts. Compared to the sliding contact between the shaft-like parts and the support base, the rolling contact between the shaft-like parts and the driven wheels results in less rolling friction than sliding friction. This makes the shaft-like parts easier to rotate, saves energy, and reduces wear on the support base caused by friction. The rolling contact also reduces vibration during part rotation and improves the accuracy of circular runout detection. Multiple driven wheels form a receiving groove, distributing the weight of the parts and reducing rotational resistance.

[0010] Optionally, a feeding mechanism is also included, which includes a conveyor plate, a conveying drive source, and a lifting drive source. The conveyor plate has a feeding position for accommodating shaft-type parts. The lifting drive source is used to drive the conveyor plate to rise and fall. The conveyor plate can be moved to a position above the support base, and the conveyor plate can also be moved to a position below the top of the support base. The conveying drive source is used to drive the conveyor plate to move horizontally, and the conveyor plate can be moved to a position where the feeding position and the receiving groove are aligned in the vertical direction.

[0011] By adopting the above technical solution, the lifting drive source and the conveying drive source work together to lift the shaft parts to be straightened behind the conveyor plate and move them towards the friction wheel. After moving them into position, the shaft parts are placed in the receiving slot of the support base, realizing automated feeding, further reducing manpower, and achieving precise alignment between the feeding position and the receiving slot, avoiding manual feeding errors. Furthermore, the conveying drive source and the clamping drive source work together. When the conveying drive source needs to drive the conveyor plate towards the friction wheel, the clamping drive source drives the friction wheel to rise, creating space for the shaft parts to move and be placed on the support base, avoiding interference between the friction wheel and the shaft parts or the conveyor plate. The coordinated lifting and translation achieves seamless connection of the "feeding-straightening-unloading" process, improving efficiency.

[0012] Optionally, it also includes a frame and a feeding mechanism. The rotating mechanism, detection module, straightening mechanism, feeding mechanism and feeding mechanism are all located on the frame. There are multiple feeding positions. The conveyor plate is also provided with a transmission position and a feeding position for accommodating shaft parts. The transmission position and the feeding position are both flush with the feeding position in the vertical direction. The transmission position, the feeding position and the feeding position are arranged along the driving direction of the conveying drive source. The conveyor plate can be moved to align the feeding position with the accommodating groove (111) in the vertical direction. The frame is provided with a transition member, on which a plurality of transition positions for accommodating shaft-type parts are formed. The plurality of transition positions are arranged along the driving direction of the conveying drive source. The conveying plate can be moved to a position where the conveying position is aligned vertically with at least two transition positions. The conveying plate can also be moved to a position where the loading position is aligned vertically with at least one transition position. The conveying plate can be moved to a position where the conveying position and the loading position are above the transition positions. The conveying plate can also be moved to a position where the conveying position and the loading position are below the transition positions.

[0013] By adopting the above technical solution, since the conveyor plate is also equipped with a loading position, a transmission position, and a unloading position, the conveyor plate simultaneously transports the shaft parts to be straightened to the receiving slot of the support base and the straightened shaft parts to the unloading plate. Furthermore, multiple transition positions cooperate with the conveyor plate; the transmission position moves the shaft parts on the transition positions closer to the support base, and the transition pieces temporarily store the parts to be straightened, optimizing the production cycle and avoiding equipment waiting. Ultimately, the loading of unstraightened parts and the unloading of straightened parts are achieved simultaneously, using only one conveyor plate, further improving processing efficiency.

[0014] Optionally, the unloading mechanism includes an unloading platform and an unloading plate, the unloading plate connecting the support base and the unloading platform, the unloading plate being inclined, the end of the unloading plate near the support base being higher than the end of the unloading plate near the unloading platform, and the conveying plate being used to transfer the straightened shaft parts to the unloading plate.

[0015] By adopting the above technical solution, after the conveyor plate transports the straightened shaft parts to the unloading plate, the shaft parts roll along the unloading plate to the unloading platform under the action of gravity due to the inclined setting of the unloading plate. This saves energy and simplifies the structure. The shaft parts can be stacked on the unloading platform without affecting the straightening process at the support, thus realizing automated unloading.

[0016] Optionally, the system also includes a frame, on which the rotating mechanism, detection module, and straightening mechanism are all mounted. The frame is provided with a slide rail, and the support base, detection module, pressing drive source, and straightening drive source are all slidably mounted on the slide rail in a direction parallel to the rotation axis of the friction wheel. The support base, detection module, pressing drive source, straightening drive source, and slide rail are all provided with a locking structure to fix themselves.

[0017] By adopting the above technical solution, the support base, detection module, clamping drive source, and straightening drive source are slidably mounted on the slide rail, and their positions can be adjusted to accommodate shaft parts of different lengths, improving the applicability of the automatic straightening machine. The locking structure ensures that the positions of each module are fixed during straightening, guaranteeing the stability of the straightening process.

[0018] Optionally, it also includes a frame, on which the rotating mechanism, detection module, straightening mechanism and feeding mechanism are all mounted. The feeding mechanism also includes two sets of conveying components and an adjustment drive component. The conveying components are located on the side of the conveying plate away from the support base. The conveying components are slidably mounted on the frame in a direction parallel to the rotation axis of the friction wheel, and the two sets of conveying components can move towards or away from each other. The adjustment drive component is used to drive the two sets of conveying components to move synchronously.

[0019] By adopting the above technical solution, the two sets of conveying components can move towards or away from each other, and the spacing can be adjusted to accommodate parts of different diameters. Adjusting the drive component ensures that the conveying components move symmetrically, maintaining the centered transport of parts.

[0020] Optionally, the feeding mechanism further includes a triggering component and a feeding box. The feeding box is located above the ends of the two conveying components that are away from the straightening mechanism. Two adjusting plates are movably arranged inside the feeding box. The adjusting drive component is also used to drive the adjusting plates to move synchronously with different conveying components. A feeding port is opened at the top of the feeding box. The box wall and the two adjusting plates form a discharge port at the bottom of the feeding box. A stop block is movably installed on the adjusting plate. The stop block is used to press against the axial end of the shaft part. The triggering component is used to drive the stop block to disengage from the axial end of the shaft part.

[0021] By adopting the above technical solution, the outlet size matches the part size, and the stop block controls the number of parts dropped at a time. When a shaft-like part falls onto the conveyor belt, another shaft-like part above it falls next to it under gravity. At this time, the upper shaft-like part is located at the outlet. As the conveyor belt continues to rotate forward, the trigger component stops and locks the stop block. The stop block can move to abut against the axial end of the shaft-like part located at the outlet, preventing the shaft-like part at the outlet from continuing to fall and interfering with the conveying assembly, thus ensuring the transmission stability of the conveying assembly. The adjusting plate moves synchronously to change the size of the inner cavity of the feeding box to accommodate shaft-like parts of different lengths.

[0022] Optionally, the conveying assembly includes a conveyor frame and a conveyor belt. The conveyor belt is rotatable relative to the conveyor frame. The conveyor belt has multiple conveying grooves arranged along its conveying direction. These grooves are used to place shaft-like parts. The triggering assembly includes a transmission block and a transmission rod. A telescopic groove is formed on the surface of the conveyor groove near the conveyor frame. The transmission block is movably disposed within the telescopic groove. A transmission groove is formed on the surface of the conveyor frame near the conveyor belt for the end of the transmission block to be inserted into. A reset elastic element is provided between the transmission block and the bottom wall of the telescopic groove. This reset elastic element is used to drive the transmission block to insert into the transmission groove. An inclined guide slope is formed on the surface of the transmission block near the support base. The distance between the guide slope and the bottom wall of the telescopic groove decreases along the conveying direction of the conveyor belt. The guide slope is used for... The transmission rod is slidably abutting against the wall of the transmission groove. A sliding groove communicating with the transmission groove is opened on the surface of the conveyor frame near the loading box. The transmission rod is movably disposed in the sliding groove. An inclined transmission surface is formed on the surface of the transmission rod near the transmission block. The distance between the inclined transmission surface and the transmission block increases along the direction near the bottom wall of the sliding groove. The inclined transmission surface is used to slide against the transmission block. A sliding groove is opened on the adjusting plate. The stop block is slidably disposed in the sliding groove. A blocking elastic element is provided between the stop block and the bottom wall of the sliding groove. The blocking elastic element is used to drive the stop block to move to abut against the axial end of the shaft-like part. The stop block is located above the transmission rod. An inclined unlocking surface is formed on the surface of the stop block near the transmission rod. The transmission rod is used to slide against the unlocking surface to press the stop block back into the sliding groove.

[0023] By adopting the above technical solution, when a conveying trough on the conveyor belt rotates to align with the transmission trough, the reset elastic element drives the end of the transmission block to insert into the transmission trough. The end of the transmission block slides against the transmission ramp on the transmission rod, causing the transmission rod to move towards the stop until the end of the transmission rod slides against the unlocking ramp on the stop, pressing the stop back into the sliding groove. This disengages the stop from the end of the shaft-like part, allowing the shaft-like part located at the discharge port to fall into the conveying trough. Through the mechanical linkage of the transmission block, transmission rod, and ramp, the stop is automatically pushed open when the conveying trough is in position, achieving precise timing control. The reset elastic element and the blocking elastic element ensure that each component automatically resets after triggering, eliminating the need for additional sensors and drive sources, thus saving energy. By driving the stop to press against the axial end of the shaft-like part through the blocking elastic element, the falling speed of the shaft-like part at the discharge port can be slowed down. Under the pressure of the stop, the falling speed of the shaft-like part is slower than the rotation speed of the conveyor belt, preventing the shaft-like part from causing jamming on the conveyor belt.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By using automated equipment to detect and straighten the circular runout of shaft parts, the machined shaft parts are made with high precision, saving manpower and improving processing efficiency; 2. Achieve seamless connection between the "feeding-straightening-unloading" process, improve efficiency, optimize production cycle, and avoid equipment waiting time; 3. Automatic straightening machines can be applied to shaft parts of different sizes, thus improving their applicability. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0037] Example 1: Embodiment 1 of this application discloses an automatic straightening machine. (Refer to...) Figure 1 and Figure 2 The automatic straightening machine includes a frame 5, a rotating mechanism 1, a detection module 2, and a straightening mechanism 3. The rotating mechanism 1, detection module 2, and straightening mechanism 3 are all mounted on the frame 5. The rotating mechanism 1 includes a support base 11, a pressing drive source 12, a rotation drive source 13, and a friction wheel 14. The support base 11 has a receiving groove 111 for accommodating the end of a shaft-like part. The pressing drive source 12 drives the friction wheel 14 to press against the circumferential sidewall of the shaft-like part placed in the receiving groove 111. The rotation drive source 13 drives the friction wheel 14 to rotate. The detection module 2 detects the circular runout of the shaft-like part. The straightening mechanism 3 includes a straightening drive source 31 and a top block 32. The straightening drive source 31 drives the top block 32 to press against the circumferential sidewall of the shaft-like part. The direction in which the straightening drive source 31 drives the top block 32 is the same as the direction in which the pressing drive source 12 drives the friction wheel 14.

[0038] Reference Figure 1 and Figure 2The automatic straightening machine also includes a feeding mechanism 4 mounted on the frame 5. The feeding mechanism 4 includes a conveying assembly 44 and a conveying plate 41. The conveying assembly 44 is located on the side of the conveying plate 41 away from the support base 11. The support base 11, the conveying plate 41, and the conveying assembly 44 are arranged in a front-to-back direction, with the vertical direction being up and down, and the axial direction of the shaft parts being left and right. The conveying assembly 44 conveys the shaft parts in a back-to-forefront direction, transporting them to the foremost position.

[0039] Reference Figure 3 The conveying assembly 44 includes two sets, corresponding to the axial ends of the shaft-like parts respectively. The conveying assembly 44 includes a conveyor frame 441 and a conveyor belt 442, which is rotatable relative to the conveyor frame 441. The conveyor belt 442 is composed of multiple rigid conveying components (not shown in the figure), which are arranged in a front-to-back direction and rotatably connected in sequence. The conveyor belt 442 is driven to rotate by a motor and a drive shaft. Each conveying component has a "V"-shaped conveying groove 120 for placing the axial end of the shaft-like part.

[0040] Reference Figure 2 and Figure 4 and Figure 5 The conveyor plate 41 has a loading position 411, which is a "V"-shaped groove on the upper surface of the conveyor plate 41 for accommodating the axial end of shaft-type parts. The loading mechanism 4 also includes a conveying drive source 42 and a lifting drive source 43. The lifting drive source 43 is used to drive the conveyor plate 41 to move up and down, and the conveying drive source 42 is used to drive the conveyor plate 41 to move in the front-back direction. In this embodiment, both the conveying drive source 42 and the lifting drive source 43 are cylinders, and the drive rods of the conveying drive source 42 and the lifting drive source 43 are fixedly connected to the conveyor plate 41. The conveyor plate 41 can be moved to a position where the loading position 411 is above the support base 11, and the conveyor plate 41 can also be moved to a position where the loading position 411 is below the top of the support base 11. The conveyor plate 41 can also be moved to a position where the loading position 411 is aligned vertically with the receiving groove 111.

[0041] Reference Figure 2 The conveyor plate 41 also has a discharge position 413 and multiple transmission positions 412. Both the transmission positions 412 and the discharge positions 413 are "V"-shaped grooves formed on the upper surface of the conveyor plate 41, which are used to accommodate the axial ends of shaft-type parts. Both the transmission positions 412 and the discharge positions 413 are flush with the loading positions 411 in the vertical direction, and the transmission positions 412, loading positions 411 and discharge positions 413 are arranged sequentially from back to front. The conveyor plate 41 can be moved until the discharge position 413 is aligned with the receiving groove 111 in the vertical direction.

[0042] Reference Figure 2A transition member 7 is fixedly mounted on the support base 11. The transition member 7 has multiple transition positions 71 arranged in the front-rear direction. Each transition position 71 is a "V"-shaped groove formed on the upper surface of the transition member 7 to accommodate the axial end of a shaft-like part. The transition member 7 is located between the support base 11 and the conveying assembly 44 in the front-rear direction. The conveyor plate 41 can be moved to a position 412 where it is vertically aligned with at least two transition positions 71. The conveyor plate 41 can also be moved to a position 411 where it is vertically aligned with at least one transition position 71. The conveyor plate 41 can be moved to a position where the conveyor position 412 and the position 411 are above the transition positions 71. The conveyor plate 41 can also be moved to a position where the conveyor position 412 and the position 411 are below the transition positions 71.

[0043] Reference Figure 1 and Figure 2 In this embodiment, the pressing drive source 12 is an electric cylinder, the drive rod of the pressing drive source 12 is fixedly connected to the rotation drive source 13, the rotation drive source 13 is a motor, and the output shaft of the rotation drive source 13 is fixedly connected to the friction wheel 14.

[0044] Reference Figure 2 Multiple friction wheels 14 are provided. In this embodiment, two friction wheels 14 are provided. One friction wheel 14 is a grinding wheel, and the other friction wheel 14 is made of an elastic material. In this embodiment, the friction wheel 14 made of elastic material is a rubber wheel. The friction wheels 14 are used to press shaft-like parts onto the support base 11.

[0045] Reference Figure 2 The rotating mechanism 1 also includes a plurality of driven wheels 15 rotatably mounted on the support base 11. In this embodiment, there are two sets of driven wheels 15, each set corresponding to one of the two friction wheels 14. Each set of driven wheels 15 has two wheels, and the receiving groove 111 is formed by two adjacent driven wheels 15. The driven wheels 15 are used for rolling contact with shaft-like parts.

[0046] Reference Figure 1 and Figure 2 The detection module 2 is an infrared sensor 21, located directly below the top block 32. Both the infrared sensor 21 and the top block 32 are located at the center of the shaft-like part along its axial direction, causing the top block 32 to press against the center of the shaft-like part. In this embodiment, the straightening drive source 31 is an electric cylinder, and its drive rod is fixedly connected to the top block 32. The straightening drive source 31 is used to drive the top block 32 to rise and fall. The straightening drive source 31 is electrically connected to the infrared sensor 21.

[0047] Reference Figure 4 and Figure 5The automatic straightening machine also includes a feeding mechanism 6, which includes a feeding table 61 and a feeding plate 62. The feeding table 61, the feeding plate 62, and the support base 11 are arranged in a front-to-back direction. The feeding plate 62 is fixedly mounted on the support base 11 and connects the feeding table 61 and the support base 11. The feeding plate 62 is inclined, with the end of the feeding plate 62 near the support base 11 higher than the end of the feeding plate 62 near the feeding table 61. The conveyor plate 41 is used to transfer the straightened shaft parts on the support base 11 to the feeding plate 62.

[0048] Reference Figure 1 and Figure 2 In this embodiment, the pressing drive source 12, the rotation drive source 13, the support base 11, the transmission plate 41 and the transition piece 7 are all provided in two sets and correspond one to one. The two sets of support base 11, transmission plate 41 and transition piece 7 correspond to the two friction wheels 14 respectively, that is, they correspond to the two ends of the shaft part respectively.

[0049] Reference Figure 1 and Figure 2 and Figure 5 The automatic straightening machine also includes a locking structure 9. A slide rail 8 is fixedly mounted on the frame 5. The support base 11, detection module 2, conveyor plate 41, clamping drive source 12, and straightening drive source 31 are all slidably mounted on the slide rail 8 in the left-right direction to accommodate shaft parts of different axial dimensions. The locking structure 9 includes threaded holes 91 formed in the support base 11, detection module 2, conveyor plate 41, clamping drive source 12, and straightening drive source 31, as well as screws (not shown in the figure). The screws pass through the threaded holes 91 to lock the support base 11, detection module 2, conveyor plate 41, clamping drive source 12, and straightening drive source 31 relative to each other on the slide rail 8.

[0050] The implementation principle of an automatic straightening machine in Embodiment 1 of this application is as follows: the conveying assembly 44 transports shaft-like parts to the front of the conveying assembly 44, and the conveying plate 41 conveys the shaft-like parts forward one by one, so that the shaft-like parts are transported from the front of the conveying assembly 44 to the transition piece 7, and then to the support base 11. At the same time, the straightened shaft-like parts on the support base 11 are transported to the unloading plate 62, so that the shaft-like parts roll from the unloading plate 62 to the unloading table 61 under the action of gravity. Before the conveying plate 41 transports the shaft-like parts, the pressure drive source 12 drives the rotation drive source 13 and the friction wheel 14 to lift. After one transmission is completed, the clamping drive source 12 drives the rotation drive source 13 and the friction wheel 14 to descend, so that the friction wheel 14 presses the shaft part onto the support base 11. The rotation drive source 13 drives the friction wheel 14 to rotate, causing the shaft part to rotate. The detection module 2 detects the circular runout of the shaft part. The friction wheel 14 rotates the shaft part until the bent protrusion faces upward. The straightening drive source 31 drives the top block 32 to descend, pressing against the bent protrusion of the shaft part. The straightening drive source 31 then drives the top block 32 to rise. The rotation drive source 13 drives the friction wheel 14 to rotate, causing the shaft part to rotate. The detection module 2 detects the circular runout of the shaft part. This cycle continues until the shaft part is straightened.

[0051] Example 2: Reference Figure 6 Unlike Embodiment 1, in this embodiment, the two sets of conveying components 44 are slidably mounted on the frame 5 in the left-right direction to accommodate shaft parts with different axial dimensions. The feeding mechanism 4 also includes an adjustment drive component 45, which is used to drive the two sets of conveying components 44 to move towards or away from each other.

[0052] Reference Figure 6 The adjustment drive assembly 45 includes an adjustment handle 451, a lead screw 452, and two sliders 453. The adjustment handle 451 is fixedly connected to the lead screw 452. The lead screw 452 is rotatably mounted on the frame 5. The lead screw 452 is a bidirectional lead screw, and its two reverse threads correspond to the two sets of transmission assemblies 44 respectively. The two sliders 453 are threadedly connected to the two reverse threads of the lead screw 452, and are fixedly connected to the two transmission frames 441 respectively. The sliders 453 are slidably mounted on the frame 5 in the left-right direction.

[0053] Reference Figure 6The feeding mechanism 4 also includes a feeding box 47, which is located directly above the front end of the conveying assembly 44 and is fixedly mounted on the frame 5. The feeding box 47 has an inlet 471 at its top and an outlet 472 at its bottom. The outlet 472 is formed by the box wall of the feeding box 47 and two adjusting plates 100 enclosing the bottom of the feeding box 47. The size of the outlet 472 is adapted to the size of the shaft parts, while the size of the inlet 471 is larger than the size of the outlet 472. Two adjusting plates 100 are slidably mounted in the inner cavity of the feeding box 47 in the left-right direction. The two adjusting plates 100 are fixedly connected to two sliders 453, which drive the adjusting plates 100 to move synchronously with the conveying assembly 44. The adjusting plates 100 are used to adjust the available inner cavity size of the feeding box 47 and the sizes of the inlet 471 and outlet 472 to accommodate shaft parts with different axial dimensions.

[0054] Reference Figure 7 and Figure 8 Each of the two adjusting plates 100 has a sliding groove 101 on its lower, opposite surfaces. A stop block 110 is slidably mounted in the sliding groove 101 in the left-right direction. A blocking elastic element 140, which is a compression spring, is pressed between the stop block 110 and the bottom wall of the sliding groove 101. The blocking elastic element 140 is used to drive the stop block 110 to pop out of the sliding groove 101 to press against the axial end of the shaft part, preventing the shaft part from falling out of the feed box 47 from the discharge port 472. An unlocking ramp 112 is formed on the lower surface of the stop block 110. The unlocking ramp 112 is inclined in the direction that moves further upward away from the bottom wall of the telescopic groove 121.

[0055] Reference Figure 8 The feeding mechanism 4 also includes a trigger component 46, which is used to drive the stop 110 to move into the sliding groove 101, so that the stop 110 disengages from the axial end of the shaft part, and the shaft part can fall out of the feeding box 47 from the discharge port 472.

[0056] Reference Figure 8 and Figure 9 and Figure 10The triggering component 46 includes a transmission block 461. The conveyor trough 120 and the conveyor frame 441 are arranged in a left-right direction. Multiple telescopic grooves 121 are formed on the surface of the conveyor belt 442 near the conveyor frame 441, each corresponding to a conveyor trough 120. The transmission block 461 is slidably installed within the telescopic groove 121 in a left-right direction. A reset elastic element 130, a compression spring, is press-fitted between the transmission block 461 and the bottom wall of the telescopic groove 121. The reset elastic element 130 is used to drive the transmission block 461 to pop out of the telescopic groove 121. A chamfered guide slope 463 is formed on the front side of the transmission block 461, inclined towards the bottom wall of the telescopic groove 121. The elasticity of the reset elastic element 130 is greater than the elasticity of the blocking elastic element 140.

[0057] Reference Figure 10 The surface of the conveyor frame 441 near the conveyor belt 442 is provided with a transmission groove 443 for the insertion of the transmission block 461. The front groove wall of the transmission groove 443 is used to slide against the guide slope 463 to press the transmission block 461 back into the telescopic groove 121.

[0058] Reference Figure 8 and Figure 10 The trigger assembly 46 also includes a transmission rod 462. A groove 444 communicating with the transmission slot 443 is formed on the upper surface of the transmission frame 441, and the transmission rod 462 is slidably installed in the groove 444 in the vertical direction. An inclined transmission surface 464 is formed on the surface of the transmission rod 462 near the transmission block 461. The inclined transmission surface 464 is inclined upwards towards the transmission block 461. When the transmission block 461 is inserted into the transmission slot 443, the transmission block 461 slides against the inclined transmission surface 464, causing the transmission rod 462 to move upwards, so that the upper end of the transmission rod 462 passes through the groove 444. The transmission rod 462 is located below the stop block 110. When the transmission rod 462 moves upwards, it slides against the unlocking inclined surface 112, pressing the stop block 110 back into the sliding slot 101.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
