Description

Technical Field

[0001] The embodiments of the present invention relate to the field of screw processing technology, and more specifically, to a heading machine with a low scrap rate for processing screws. Background Technology

[0002] A heading machine is a mechanical device used to produce fasteners such as screws and bolts. It mainly processes raw materials into screw heads with specific shapes through a heading process. Heading machines are widely used in industries such as hardware manufacturing, automobiles, home appliances, and electronics. Its core function is to heat or cool one end of the raw material to a certain temperature and form the required heading shape through impact force.

[0003] Patent publication number CN209902642U relates to a screw heading machine with low scrap rate. The machine includes a frame with two sets of No. 1 positioning slots and two sets of No. 2 positioning slots on its inner wall. A heading machine body is fixedly mounted on the top of the frame, and a No. 1 hydraulic pump is fixedly mounted on the lower end of the head heading machine body. A pressure shaft is movably mounted on the end of the No. 1 hydraulic pump away from the head heading machine body. No. 2 hydraulic pumps are fixedly mounted on both sets of No. 2 positioning slots. This screw heading machine with low scrap rate, through the No. 2 slots on the two sets of top plates, and the movable mounting of the ends of the two sets of top plates away from the No. 2 slots via springs to top blocks, can firmly clamp the lower half of the screw, preventing the screw material from shifting downwards during head machining, thereby improving processing efficiency and reducing the scrap rate.

[0004] In the aforementioned patent, the lower half of the screw is firmly clamped to prevent the screw processing material from moving downwards when processing the screw head. However, when processing multiple batches of screws, the efficiency of screw heading is affected due to the individual processing mode. Therefore, a heading machine with high efficiency and low scrap rate for processing screws is designed. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a screw heading machine with a low scrap rate for processing screws, which solves the technical problem in the prior art that the efficiency of screw heading is affected by the individual processing mode when heading multiple batches of screws.

[0006] According to one aspect, at least one embodiment of the present invention provides a heading machine with a low scrap rate for processing screws, comprising a main body, a rotating shaft rotatably mounted on the surface of the main body, a heading device for heading materials being provided on the circumferential surface of the rotating shaft, the heading device including a conveyor plate fixedly mounted on the circumferential surface of the rotating shaft, a feeding mechanism for conveying and processing materials being provided on the surface of the main body, a discharging mechanism for facilitating material discharge being provided on the surface of the main body, a processing frame fixedly mounted on the top of the main body, an electric push cylinder slidably mounted on the surface of the processing frame, an adaptation block slidably mounted on the inner wall of the conveyor plate, and a telescopic spring rod fixedly mounted on the surface of the conveyor plate; The output end of the electric push cylinder is fixedly installed with a diagonal rod one, the surface of the main body is slidably installed with a diagonal rod two, the surface of the main body is fixedly installed with a telescopic spring rod two, and the end of the diagonal rod two away from the telescopic spring rod two is fixedly installed with a clamping block.

[0007] For example, in a screw heading machine with a low scrap rate provided in at least one embodiment of the present invention, the free end of the telescopic spring rod is fixedly connected to the adaptation block. The surface of the adaptation block is provided with an arc surface for contacting and fitting with the surface of the material to improve the conveying stability. The stability and reliability of material conveying to the processing is improved by the cooperation between the conveying disc and the main body. At the same time, it adapts to materials of different lengths, improving the adaptability and versatility of the equipment.

[0008] According to another aspect, at least one embodiment of the present invention also provides a heading machine with low scrap rate for processing screws, wherein a first inclined rod is slidably connected to the main body, a second inclined rod is slidably connected to the main body, and one end of the rotating shaft is connected to the motor output end, thereby reducing debugging errors when changing specifications, improving the dimensional consistency of batch products, and thus reducing the scrap rate.

[0009] For example, in a screw-making heading machine with a low scrap rate provided in at least one embodiment of the present invention, the surface of the inclined rod one near the telescopic spring rod two is provided with an inclined surface one for contacting and squeezing the inclined rod two to move towards the clamping block, and the end of the inclined rod two away from the clamping block is provided with an inclined surface two for assisting the inclined rod one in receiving force. The material moves downward and is buffered by the adaptation block to avoid direct action on the material during heading, which would cause the material to bend or deform.

[0010] According to another aspect, at least one embodiment of the present invention also provides a heading machine with a low scrap rate for processing screws. The surface of the main body is provided with a correction device for correcting the material after heading. The correction device includes a fixing plate, which is fixedly installed on the surface of the main body. A motor is fixedly installed on the surface of the fixing plate. The shaft of the motor is threadedly connected to a sliding frame through a screw. A cleaning cylinder rotatably passes through the surface of the sliding frame. A rotating rod is rotatably installed on the top of the cleaning cylinder. The surface of the sliding frame is rotatably penetrated by a deburring cylinder, and the surface of the deburring cylinder is rotatably penetrated by a rotating rod two. A turntable is fixedly installed at one end of the rotating rod two near the deburring cylinder, and a beveled block is fixedly installed on the surface of the turntable. A sliding plate is slidably installed on the inner wall of the deburring cylinder, and a telescopic spring rod three is fixedly installed on the inner wall of the deburring cylinder. A deburring ring is slidably installed on the inner wall of the deburring cylinder. The cleaning cylinder rotates under the action of the rotating rod one, which drives the brush bristles to rotate. The rotating brush bristles clean the top of the material to ensure that the head surface is smooth.

[0011] For example, in a screw heading machine with low scrap rate provided in at least one embodiment of the present invention, a reciprocating thread groove is provided at the output end of a motor, the sliding frame is slidably connected to the motor, and the deburring ring is fixedly connected to the sliding plate to avoid appearance defects or screening being affected by impurities.

[0012] According to another aspect, at least one embodiment of the present invention also provides a heading machine with low scrap rate for processing screws. The sliding frame is connected to the output end of the motor by a thread, and the rotating rod is connected to the output end of the motor by a transmission belt. The inner wall of the cleaning cylinder is provided with bristles for cleaning the surface of the material. The surface of the material is deburred by a deburring ring, which improves the consistency of the material and facilitates the efficiency and accuracy of subsequent screening.

[0013] For example, in a screw heading machine with a low scrap rate provided in at least one embodiment of the present invention, a transmission belt is connected between the rotating rod 2 and the output end of the motor 1, the surface of the oblique cutting block is provided with an arc surface 2 for contacting and pressing the sliding plate to move downward, and the free end of the telescopic spring rod 3 is fixedly connected to the sliding plate.

[0014] According to another aspect, at least one embodiment of the present invention also provides a low scrap rate heading machine for processing screws, wherein the surface of the deburring cylinder is provided with a screening device for screening unqualified materials, the screening device includes a connecting inclined rod, the connecting inclined rod is fixedly installed on the surface of the deburring cylinder, an inclined block is slidably installed on the surface of the main body, a pusher block is fixedly installed at the end of the inclined block away from the connecting inclined rod, and a telescopic spring rod is fixedly installed on the surface of the main body; A screen plate is fixedly installed on the surface of the discharge mechanism, and a connecting block is fixedly installed on the surface of the screen plate. A limit plate is slidably installed on the inner wall of the discharge mechanism to prevent material from clogging and jamming at the discharge port, thereby affecting the stability and smoothness of the equipment operation and further improving the operating efficiency of the equipment.

[0015] For example, in a screw heading machine with low scrap rate provided in at least one embodiment of the present invention, the connecting inclined rod is slidably connected to the main body, the free end of the telescopic spring rod four is fixedly connected to the inclined block, the limiting plate is fixedly connected to the connecting block, and the surface of the screening plate is provided with a guiding arc surface for guiding materials with higher than standard values, so as to realize the screening process of whether the material is qualified or not. At the same time, the cooperation of the cleaning cylinder and the deburring cylinder avoids the impact of impurities or foreign objects on the surface of the material on the subsequent screening effect and accuracy, and avoids the waste of qualified products or the flow of unqualified products into the next process, thus ensuring the quality of the finished product.

[0016] The beneficial effects of the embodiments of the present invention are as follows: In this invention, the material rotates under the action of the rotating shaft until it reaches the heading position for processing. Then, the material is conveyed by the conveyor plate until it contacts the surface of the discharge mechanism. After processing, the material moves away from the conveyor plate under the action of the discharge mechanism. The cooperation between the conveyor plate and the main body improves the stability and reliability of material conveying to the processing area, while adapting to materials of different lengths, improving the adaptability and versatility of the equipment. It also reduces debugging errors when changing specifications, improves the dimensional consistency of batch products, and thus reduces the scrap rate. The output end of the electric push cylinder continues to move downwards to head the material. Simultaneously, the material moves downwards under the action of the electric push cylinder. The downward movement of the material is then buffered by the adaptation block to prevent the heading action from directly impacting the material, which could lead to bending or deformation. When the telescopic spring rod loses its effect, it deforms and restores its original shape, causing the adaptation block to move upwards until the material is reset. This ensures the positioning accuracy of subsequent processes and avoids secondary processing defects caused by material position deviation. The clamping block clamps and fixes the material, improving its stability during heading and preventing the material from shifting or rotating due to the impact force of the punch.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0021] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-7 As shown, an embodiment of the present invention illustrates a low-scrap heading machine for processing screws, comprising: a main body 1, a rotating shaft 2 rotatably mounted on the surface of the main body 1, a heading device for heading materials provided on the circumferential surface of the rotating shaft 2, the heading device including a conveying disc 3 fixedly mounted on the circumferential surface of the rotating shaft 2, a feeding mechanism 4 for conveying and processing materials provided on the surface of the main body 1, a discharging mechanism 5 for facilitating material discharge on the surface of the main body 1, a processing frame 61 fixedly mounted on the top of the main body 1, an electric push cylinder 62 slidably mounted on the surface of the processing frame 61, an adaptation block 63 slidably mounted on the inner wall of the conveying disc 3, and a telescopic spring rod 64 fixedly mounted on the surface of the conveying disc 3. The telescopic spring rod 64 deforms and recovers, causing the adaptation block 63 to move upward until the material is reset.

[0027] In this example, the material is conveyed towards the conveyor plate 3 via the feeding mechanism 4. Under the action of the feeding mechanism 4, the material is conveyed until it contacts the adapting block 63. Then, the rotating shaft 2 rotates under the action of the motor output end. The rotation of the rotating shaft 2 drives the conveyor plate 3 to rotate, and at the same time, the rotation of the conveyor plate 3 drives the material to rotate until it contacts the main body 1. At this time, the material is stably conveyed under the action of the adapting block 63 and the main body 1. Then, the material rotates under the action of the rotating shaft 2 until it reaches the heading position for processing. Then, the material rotates and is conveyed under the action of the conveyor plate 3 until it contacts the surface of the discharge mechanism 5. Then, the processed material moves away from the conveyor plate 3 under the action of the discharge mechanism 5. The cooperation between the conveyor plate 3 and the main body 1 improves the stability and reliability of the material conveying to the processing, while adapting to materials of different lengths, improving the adaptability and versatility of the equipment, reducing debugging errors when changing specifications, improving the dimensional consistency of batch products, and thus reducing the scrap rate.

[0028] An inclined rod 65 is fixedly installed at the output end of the electric push cylinder 62. An inclined rod 66 is slidably installed on the surface of the main body 1. A telescopic spring rod 67 is fixedly installed on the surface of the main body 1. A clamping block 68 is fixedly installed at the end of the inclined rod 66 away from the telescopic spring rod 67.

[0029] The free end of the telescopic spring rod 64 is fixedly connected to the adapting block 63. The surface of the adapting block 63 is provided with an arc surface for contacting and fitting with the surface of the material to improve the conveying stability. The material is conveyed stably under the action of the adapting block 63 and the main body 1.

[0030] The first inclined rod 65 is slidably connected to the main body 1, the second inclined rod 66 is slidably connected to the main body 1, one end of the rotating shaft 2 is connected to the motor output end, and the movement of the second inclined rod 66 drives the clamping block 68 to move until it contacts and clamps the material.

[0031] The surface of the first inclined rod 65 near the second telescopic elastic rod 67 is provided with an inclined surface 1 for contacting and pressing the second inclined rod 66 to move towards the clamping block 68. The end of the second inclined rod 66 away from the clamping block 68 is provided with an inclined surface 2 for assisting the first inclined rod 65 in receiving force. The first inclined rod 65 moves downward until it contacts and presses the second inclined rod 66 to move towards the clamping block 68.

[0032] When the material rotates under the action of the conveyor disc 3 until it reaches the bottom of the electric pusher cylinder 62, the electric pusher cylinder 62 is activated. The output end of the electric pusher cylinder 62 moves downward, driving the first inclined rod 65 to move. The first inclined rod 65 moves downward until it contacts and squeezes the second inclined rod 66, moving it towards the clamping block 68. At this time, the movement of the second inclined rod 66 drives the clamping block 68 to move until it contacts and clamps the material. Then, the output end of the electric pusher cylinder 62 continues to move downward to head the material. At the same time, the material moves downward under the action of the electric pusher cylinder 62, and then the material moves towards... The downward movement is buffered by the adapting block 63 to prevent the downward force from directly impacting the material during the heading process, which could lead to bending or deformation of the material. Subsequently, when the telescopic spring rod 64 loses its effect, the deformation of the telescopic spring rod 64 returns to its original position, causing the adapting block 63 to move upward until the material is reset. At the same time, this ensures the positioning accuracy of subsequent processes and avoids secondary processing defects caused by material position deviation. The clamping block 68 clamps and fixes the material to improve its stability during the heading process, preventing the impact force of the punch during heading from causing the material to move up and down or rotate.

[0033] like Figures 1-7 As shown, in another embodiment of the present invention, the surface of the main body 1 is provided with a correction device for correcting the material after the heading process. The correction device includes a fixing plate 71, which is fixedly installed on the surface of the main body 1. A motor 72 is fixedly installed on the surface of the fixing plate 71. The rotating shaft of the motor 72 is threadedly connected to a sliding frame 73 through a screw. A cleaning cylinder 74 is rotatably passed through the surface of the sliding frame 73. A rotating rod 75 is rotatably installed on the top of the cleaning cylinder 74. The rotation of the transmission belt drives the rotating rod 75 to rotate, and the rotation of the rotating rod 75 drives the cleaning cylinder 74 to rotate.

[0034] In this example, after the material undergoes heading processing under the action of the electric push cylinder 62, it rotates under the action of the conveyor disc 3 until it reaches the bottom of the cleaning cylinder 74. When the electric push cylinder 62 moves downward to continue heading processing, the motor 72 is started. Since the motor 72 and the sliding frame 73 are connected by a thread, the rotation of the motor 72 drives the sliding frame 73 to move downward. The downward movement of the sliding frame 73 drives the cleaning cylinder 74 to move until it covers the material. At this time, the rotation of the motor 72 drives the transmission belt to rotate, and the rotation of the transmission belt drives the rotating rod 75 to rotate. The rotation of the rotating rod 75 drives the cleaning cylinder 74 to rotate. The rotation of the cleaning cylinder 74, under the action of the rotating rod 75, drives the brush to rotate. The rotation of the brush cleans the top of the material, ensuring that the head surface is smooth and avoiding appearance defects or screening problems caused by impurities.

[0035] The surface of the sliding frame 73 is rotatably penetrated by a deburring cylinder 76. The surface of the deburring cylinder 76 is rotatably penetrated by a rotating rod 77. A turntable 78 is fixedly installed at one end of the rotating rod 77 near the deburring cylinder 76. A beveled block 79 is fixedly installed on the surface of the turntable 78. A sliding plate 710 is slidably installed on the inner wall of the deburring cylinder 76. A telescopic spring rod 711 is fixedly installed on the inner wall of the deburring cylinder 76. A deburring ring 712 is slidably installed on the inner wall of the deburring cylinder 76. When the telescopic spring rod 711 deforms and returns to its original position, it causes the sliding plate 710 to move downward and causes the deburring ring 712 to move.

[0036] The output end of motor 72 is provided with a reciprocating threaded groove. The sliding frame 73 is slidably connected to motor 72. The deburring ring 712 is fixedly connected to the sliding plate 710. The sliding plate 710 moves downward under the action of the oblique cutting block 79, which drives the deburring ring 712 to move.

[0037] The sliding frame 73 is connected to the output end of the motor 72 by a thread, and the rotating rod 75 is connected to the output end of the motor 72 by a transmission belt. The inner wall of the cleaning cylinder 74 is provided with bristles for cleaning the surface of the material. The sliding frame 73 moves downward, driving the cleaning cylinder 74 to move until it covers the material.

[0038] A transmission belt is connected between the output end of the rotating rod 77 and the motor 72. The surface of the oblique block 79 is provided with an arc surface 2 for contacting and pressing the sliding plate 710 to move downward. The free end of the telescopic spring rod 711 is fixedly connected to the sliding plate 710. The oblique block 79 rotates to contact and press the sliding plate 710 to move downward.

[0039] When the deburring cylinder 76 moves downward under the action of the sliding frame 73 until it covers the material, the motor 1 72 rotates, driving the transmission belt 2 to rotate. The rotation of the transmission belt 2 drives the rotating rod 2 77 to rotate, which in turn drives the turntable 78 to rotate. At the same time, the rotation of the turntable 78 drives the oblique cutting block 79 to rotate. At this time, the oblique cutting block 79 rotates and contacts and squeezes the sliding plate 710 to move downward. The sliding plate 710 moves downward under the action of the oblique cutting block 79, driving the deburring ring 712 to move. Then the oblique cutting block 79 continues to rotate. When the telescopic spring rod 3 711 loses its effect on it, the telescopic spring rod 3 711 deforms and returns to its original shape, driving the sliding plate 710 to move downward and driving the deburring ring 712 to move. At this time, the deburring ring 712 removes burrs from the surface of the material, improving the consistency of the material and facilitating the efficiency and accuracy of subsequent screening.

[0040] like Figures 1-7As shown, in another embodiment of the present invention, the surface of the deburring cylinder 76 is provided with a screening device for screening unqualified materials. The screening device includes a connecting inclined rod 81, which is fixedly installed on the surface of the deburring cylinder 76. An inclined block 82 is slidably installed on the surface of the main body 1. A pusher block 83 is fixedly installed at the end of the inclined block 82 away from the connecting inclined rod 81. A telescopic spring rod 84 is fixedly installed on the surface of the main body 1.

[0041] In this example, when the deburring cylinder 76 moves downward under the action of motor 72, the downward movement of the deburring cylinder 76 drives the connecting inclined rod 81 to move. The connecting inclined rod 81 moves downward to contact and squeeze the inclined block 82, which moves towards the discharge mechanism 5. At this time, the movement of the inclined block 82 drives the pusher block 83 to move. The movement of the pusher block 83 drives the material to move until it is discharged and conveyed under the action of the discharge mechanism 5. This avoids the material from being blocked or stuck at the discharge port, which would affect the stability and smoothness of the equipment operation and further improve the operating efficiency of the equipment.

[0042] A screen plate 85 is fixedly installed on the surface of the discharge mechanism 5, and a connecting block 86 is fixedly installed on the surface of the screen plate 85. A limit plate 87 is slidably installed on the inner wall of the discharge mechanism 5. The movement of the connecting block 86 drives the limit plate 87 to move until the limit on the non-conforming port is released.

[0043] The connecting diagonal rod 81 is slidably connected to the main body 1, the free end of the telescopic spring rod 84 is fixedly connected to the inclined block 82, the limiting plate 87 is fixedly connected to the connecting block 86, and the surface of the screen plate 85 is provided with a guiding arc surface for assisting the guidance of materials with higher than standard values. Under the action of the discharge mechanism 5, the material moves to contact and pushes the screen plate 85 to move.

[0044] When standard-compliant materials move away from the conveyor plate 3 under the action of the discharge mechanism 5, the materials pass through and pass through the bottom of the screen plate 85. When non-standard materials pass through the screen plate 85, they will come into contact with the surface of the screen plate 85 due to their surface protrusions or improper deformation. At this time, the materials move and contact the screen plate 85 under the action of the discharge mechanism 5, and push the screen plate 85 to move. The movement of the screen plate 85 drives the connecting block 86 to move, and the movement of the connecting block 86 drives the limiting plate 87 to move until the limit on the non-conforming port is released. At this time, the materials fall through the non-conforming port under the action of the guiding surface of the screen plate 85, realizing the screening process of whether the materials are qualified or not. At the same time, the cooperation of the cleaning cylinder 74 and the deburring cylinder 76 avoids the impact of impurities or foreign objects on the surface of the materials on the subsequent screening effect and accuracy. It also avoids the waste of qualified products or the flow of unqualified products into the next process, ensuring the quality of the finished products.

[0045] The working principle of the above embodiments of the present invention in specific implementation is as follows: The material is conveyed towards the conveyor plate 3 through the feeding mechanism 4. Under the action of the feeding mechanism 4, the material is conveyed until it contacts the adapting block 63. Then, the rotating shaft 2 rotates under the action of the motor output end. The rotation of the rotating shaft 2 drives the conveyor plate 3 to rotate. At the same time, the rotation of the conveyor plate 3 drives the material to rotate until it contacts the main body 1. At this time, the material is stably conveyed under the action of the adapting block 63 and the main body 1. Then, the material rotates under the action of the rotating shaft 2 until it reaches the heading position for processing. Then, the material rotates and is conveyed under the action of the conveyor plate 3 until it contacts the surface of the discharge mechanism 5. Then, the processed material moves away from the conveyor plate 3 under the action of the discharge mechanism 5. The cooperation between the conveyor disc 3 and the main body 1 improves the stability and reliability of material conveying to the processing area, while adapting to materials of different lengths, thus improving the adaptability and versatility of the equipment. It also reduces debugging errors when changing specifications, improves the dimensional consistency of batch products, and consequently reduces the scrap rate. When the material rotates under the action of the conveyor disc 3 until it reaches the bottom of the electric push cylinder 62, the electric push cylinder 62 is activated. The output end of the electric push cylinder 62 moves downward, driving the first inclined rod 65 to move. The first inclined rod 65 moves downward until it contacts and squeezes the second inclined rod 66, moving it towards the clamping block 68. At this time, the movement of the second inclined rod 66 drives the clamping block 68 to move until it contacts and clamps the material. Subsequently, the output end of the electric push cylinder 62 continues to move downward to further clamp the material. During the heading process, the material moves downward under the action of the electric push cylinder 62. The material is then buffered by the adapting block 63 to prevent direct impact during heading, which could cause bending or deformation. When the telescopic spring rod 64 loses its effect, it returns to its original shape, causing the adapting block 63 to move upward until the material is reset. This ensures the positioning accuracy of subsequent processes and prevents secondary processing defects caused by material position deviation. The clamping block 68 clamps and fixes the material, improving its stability during heading and preventing the impact force from causing the material to move up and down or rotate. As the deburring cylinder 76 moves downward under the action of the sliding frame 73 until it covers the material, simultaneously... Motor 1 72 rotates, driving transmission belt 2 to rotate. Transmission belt 2 rotates, driving rod 2 77 to rotate. Rotating rod 2 77 drives turntable 78 to rotate. Simultaneously, turntable 78 rotates, driving oblique cutting block 79 to rotate. At this time, oblique cutting block 79 rotates, contacts and squeezes sliding plate 710 to move downward. Under the action of oblique cutting block 79, sliding plate 710 moves downward, driving deburring ring 712 to move. Then oblique cutting block 79 continues to rotate. When telescopic spring rod 3 711 loses its effect, telescopic spring rod 3 711 deforms and returns to its original shape, driving sliding plate 710 to move downward and driving deburring ring 712 to move. At this time, deburring ring 712 removes burrs from the surface of the material, improving the consistency of the material and facilitating the efficiency and accuracy of subsequent screening.When the deburring cylinder 76 moves downward under the action of motor 72, the downward movement of the deburring cylinder 76 drives the connecting inclined rod 81 to move. The connecting inclined rod 81 moves downward to contact and squeeze the inclined block 82, moving it closer to the discharge mechanism 5. At this time, the movement of the inclined block 82 drives the pusher block 83 to move, which in turn moves the material until it is discharged and conveyed under the action of the discharge mechanism 5. This avoids material blockage at the discharge port, which would affect the stability and smoothness of the equipment's operation, and further improves the equipment's operating efficiency. The improved operational stability and smoothness of the equipment further enhance its operating efficiency. When standard-compliant materials move away from the conveyor plate 3 under the action of the discharge mechanism 5, they pass through the bottom of the screen plate 85. When non-standard materials pass through the screen plate 85, their surface protrusions or improper deformation cause them to contact the surface of the screen plate 85. At this time, the material moves under the action of the discharge mechanism 5, contacting and pushing the screen plate 85 to move. The movement of the screen plate 85 drives the connecting block 86 to move, and the movement of the connecting block 86 drives the limiting plate 87 to move until the limiting of the non-conforming port is released. At this time, the material falls through the non-conforming port under the action of the guiding surface of the screen plate 85, realizing the screening process of whether the material is qualified or not. At the same time, the cooperation between the cleaning cylinder 74 and the deburring cylinder 76 avoids the impact of impurities or foreign objects on the surface of the material on the subsequent screening effect and accuracy. It also avoids the waste of qualified products or the flow of unqualified products into the next process, ensuring the quality of the finished product.
