Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled lathes, and particularly to a single-column numerically controlled vertical lathe. Background Art

[0002] A single-column numerically controlled vertical lathe is an advanced device for machining, belonging to a type of numerically controlled machine tool. It mainly consists of a bed, a column, a workbench, a crossbeam, a tool rest, etc. With a single column as the main support structure, it has the characteristics of relatively small floor area and compact structure. The workbench is usually located at the bottom of the machine tool and is used to clamp the workpiece to be machined, and can perform high-precision rotational motion to provide circular feed for turning machining.

[0003] A Chinese patent with the publication number CN117583628B discloses a single-column numerically controlled vertical lathe, including a workbench on the lathe. An operation console is installed on the workbench, a six-jaw chuck is arranged on the operation console, and a protective component is arranged on the upper end surface of the workbench. The position of the protective component is outside the operation console. The protective component is used to prevent waste chips from splashing during workpiece grinding. A driving component is installed on the workbench. During the use of the present invention, the lifting protective plate in the protective component rises, so that the workpiece clamped by the six-jaw chuck is inside the lifting protective plate. The waste chips generated during the turning machining of the lathe will be blocked by the lifting protective plate by 360 degrees, effectively avoiding the phenomenon of waste chip splashing during workpiece machining. At the same time, the cleaning component facilitates the cleaning of the waste chips on the workbench, ensuring the cleanliness of the workbench and improving the efficiency of workpiece machining.

[0004] In the existing related technologies, there are often the following defects: However, during the actual use of the above single-column numerically controlled vertical lathe, when using air flow to clean the residual chips generated during the turning process, although the metal residual chips can be effectively collected and cleaned, there is a risk that the metal residual chips will form dust under the action of the air flow. If these metal dusts are inhaled by the operator, long-term accumulation may cause serious damage to the respiratory system. And if the staff is relatively close to the single-column numerically controlled vertical lathe, there is also a risk that when the air flow cleans the metal residual chips, the residual chips may fly out at a high speed, causing harm to the operator's eyes, skin, etc.

[0005] Therefore, we propose a single-column numerically controlled vertical lathe. Summary of the Invention

[0006] The purpose of the present invention is to provide a single-column numerically controlled vertical lathe to solve the problems raised in the above background art.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A single-column CNC vertical lathe comprises an operating table, a column body is fixedly mounted on the side wall of the operating table, a six-jaw chuck is mounted on the surface of the operating table, and further comprises: a chip collecting structure arranged on the surface of the operating table for conveying the chips generated during the processing of metal parts above the operating table, the chip collecting structure comprises a connecting frame fixedly connected to the surface of the operating table, a first slider and a second slider are slidably mounted on the inner side of the connecting frame, a driven shaft and a driving shaft are rotatably mounted inside the first slider and the second slider respectively, a transmission rod is fixedly connected to the side walls of the driving shaft and the driven shaft, the transmission rod is spliced ​​by a middle circular rod and a round cone column at both ends, the side walls of the two transmission rods are transmission-connected with a spandex belt, the chip collecting structure further comprises a folding cylinder; a cleaning structure arranged inside the second slider for cleaning the chips adhered to the surface of the spandex belt; a pressure structure arranged on the side of the operating table for pressurizing and compressing the folding cylinder and the inner chips.

[0008] The effects achieved by the above components are: by setting up the chip collection structure, it is convenient to use the conveying method to quickly and effectively collect the metal chips of the product during the turning process above the operating table, avoiding the risk of cleaning the metal chips by methods such as the airflow method, not only facilitating the rapid collection and processing of chips during the turning of metal products on the operating table, but also improving the safety performance of clamping the metal products. By setting up the cleaning structure, it is convenient to sweep away the metal chips adhering to the surface of the spandex belt when using coolant during the processing of metal products, thereby further improving the collection efficiency of the metal chips. By setting up the pressure structure, it is convenient to steadily pressurize the metal chips on the inside of the folding cylinder. The metal chips with loose structures tend to occupy a large space, and the metal chips on the inside of the folding cylinder need to be frequently collected and dumped, thereby further improving the collection efficiency of the metal chips.

[0009] Preferably, a bidirectional screw is rotatably installed inside the connection frame, and the bidirectional screw is threadedly connected to the outer sides of the first slider and the second slider.

[0010] The effect achieved by the above components is: rotating the bidirectional screw rod can move the first slider and the second slider toward a side close to each other.

[0011] Preferably, a mounting frame is fixedly mounted on the surface of the second slider, the mounting frame is composed of an irregular rod and a circular ring, a motor is fixedly mounted on the inner side of the circular ring on the mounting frame, and the output end of the motor is fixedly connected to the driving shaft.

[0012] The effects achieved by the above components are: starting the motor will drive the driving shaft to rotate, thereby realizing the transmission of the spandex belts on the two transmission rods.

[0013] Preferably, a number of rows of barbs are fixedly connected to the side wall of the transmission rod, and the barbs are in an arc structure.

[0014] The effect achieved by the above components is that by setting the barbs with an arc structure on the side wall of the transmission rod, the stability of the transmission rod during the transmission of the spandex fabric belt is improved, and the phenomenon of pulleys during the transmission of the spandex fabric belt is avoided.

[0015] Preferably, a fixed plate is fixedly installed on the side wall of the operating table. A collecting hopper is communicated with the upper port of the fixed plate. A rectangular ring is embedded in the inner side of the fixed plate. Two rows of rotating blocks are rotatably connected to the lower surface of the fixed plate. The upper port of the folding cylinder is fixedly connected to the rectangular ring. The lower port of the folding cylinder is fixedly connected to a bottom plate. Two rectangular blocks are fixedly installed in the inner side of the collecting hopper. The lower surfaces of the two rectangular blocks are fixedly connected with telescopic rods respectively. The lower ends of the two telescopic rods are fixedly connected with a triangular prism.

[0016] The effect achieved by the above components is that the metal debris falling into the inner side of the hopper will evenly fall into the inner side of the folding cylinder along the two inclined surfaces of the triangular prism. The setting of the triangular prism realizes the guiding work of the collected metal debris and avoids the accumulation of metal debris at a single position.

[0017] Preferably, a plate is fixedly connected to the side wall of the second slider. A connecting rod is rotatably connected to the inside of the plate. A central shaft is fixedly connected to the end side of the connecting rod. A number of brush rods are fixedly connected to the side wall of the central shaft. A number of bristles are fixedly connected to the side wall of the brush rod. The two sides of the brush rod are in a bent structure.

[0018] The effect achieved by the above components is that the bristles will move relative to the metal debris on the surface of the spandex fabric belt, thus facilitating the rapid sweeping of the wet metal debris adhering to the surface of the spandex fabric belt.

[0019] Preferably, a third gear is fixedly connected to the side wall of the connecting rod. A central rod is rotatably connected to the inside of the plate. A second gear is fixedly connected to the side wall of the central rod. The tooth surface of the third gear meshes with the tooth surface of the second gear. A first gear is fixedly connected to the side wall of the driving shaft. The tooth surface of the first gear meshes with the tooth surface of the second gear.

[0020] The effect achieved by the above components is that when the driving shaft rotates, through the transmission of the first gear, the second gear and the third gear, the connecting rod can be driven to rotate. By setting the second gear as an intermediary to drive the central shaft to rotate, the central shaft can drive the brush rod to rotate in a direction opposite to the conveying direction of the spandex fabric belt.

[0021] Preferably, a comb plate frame is fixedly connected to the side wall of the operating table, and the comb plate frame is spliced by two rectangular bars and a comb plate with an arc structure.

[0022] The effects achieved by the above components are as follows: During the driving rotation process of the bristles, relative movement will occur between the bristles and the comb plate frame, which can realize the combing work of the metal debris adhering between the bristles, avoiding the phenomenon that it is not easy to handle the metal debris adhering between the bristles, and the scraped metal debris will directly fall into the inner side of the hopper for collection.

[0023] Preferably, the pressing structure includes a jack opened on the lower surface of the bottom plate, a positioning block is fixedly connected to the side wall of the fixed plate, a limiting frame is slidably connected inside the positioning block, a rectangular plate is fixedly connected to the lower end of the limiting frame, an inserting frame is slidably connected inside the rectangular plate, the size of the inserting frame is adapted to the size of the jack, a pulley is rotatably connected inside the positioning block, a pulling rope is fixedly connected to the upper surface of the rectangular plate, the pulling rope is located on the side wall of the pulley, and the other end of the pulling rope is fixedly connected to a pressing plate.

[0024] The effects achieved by the above components are as follows: Insert the inserting plate into the inner side of the jack on the bottom plate. When the metal debris is about to fill the inside of the folding cylinder, at this time, step on the pressing plate, and the pressing plate will drive the pulling rope to be pulled. The pulling rope makes relative movement with the pulley during the movement, which has the effect of changing the acting direction of the pulling force of the pulling rope. At this time, the lifting work of the rectangular plate, the inserting frame and the bottom plate can be realized. At this time, the folding cylinder will be compressed, and part of the metal debris inside the folding cylinder will squeeze the triangular prism to lift, so that the hopper inlet position at the upper port of the fixed plate is in a closed state as much as possible, which can improve the leveling and compressing effect of the metal debris inside the folding cylinder. There is still space for storing metal debris inside the compressed folding cylinder, which further improves the collection efficiency of the metal debris.

[0025] Preferably, a support plate is fixedly connected to the side wall of the operating table, and the pressing plate is slidably connected to the side wall of the support plate.

[0026] The effects achieved by the above components are as follows: By setting the pressing plate to slide inside the support plate, it plays a role in restricting the moving direction of the pressing plate, which facilitates the stable pressing work in a single direction of the pressing plate.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. The present invention sets up a chip collecting structure. By setting up a spandex cloth belt made of spandex material, firstly, the spandex material has good elastic properties, which facilitates the normal clamping work of metal products using a six-jaw chuck. Secondly, the fiber surface of spandex itself is relatively smooth, without obvious pores or rough surfaces, and iron chips are not easily attached to its surface. Moreover, spandex generally has no static electricity or a weak static electricity effect, and will not adsorb iron chips due to electrostatic attraction, improving the transmission and collection effect of metal iron chips. By setting up a chip collecting structure, it facilitates the rapid and effective collection work of metal chips of products during the turning process above the operating table by means of transmission, avoiding the risk prone to occur when using methods such as the air flow method to clean metal chips. It not only facilitates the rapid collection and treatment work of chips during the turning of metal products on the operating table, but also improves the safety performance of clamping metal products.

[0029] 2. The present invention sets up a cleaning structure. During the driving rotation of the brush bristles, relative movement will occur between the brush bristles and the comb plate frame, which can achieve the combing work of metal chips adhered between the brush bristles, avoiding the phenomenon that it is not easy to process the metal chips adhered between the brush bristles. The scraped-off metal chips will directly fall into the inner side of the hopper for collection. By setting up a cleaning structure, it facilitates the sweeping work of metal chips adhered to the surface of the spandex cloth belt when using coolant during the processing of metal products, further improving the collection efficiency of metal chips.

[0030] 3. The present invention sets up a pressing structure. There will still be space for storing metal chips inside the compressed folding cylinder, further improving the collection efficiency of metal chips. By setting up a pressing structure, it facilitates the stable pressing work of metal chips inside the folding cylinder. The loose-structured metal chips are likely to occupy a large space, and there is a phenomenon that it is necessary to frequently fill and empty the metal chips inside the folding cylinder, further improving the collection efficiency of metal chips.

Detailed implementation manners

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Please refer to Figures 1 - 13, the present invention provides a technical solution: a single-column numerically controlled vertical lathe, including an operating table 1, a column body 2 fixedly installed on the side wall of the operating table 1, and a six-jaw chuck 3 installed on the surface of the operating table 1. It further includes: a chip collection structure 4 arranged on the surface of the operating table 1 for conveying the chips generated during the processing of metal parts above the operating table 1. The chip collection structure 4 includes a connection frame 401 fixedly connected to the surface of the operating table 1. A first slider 409 and a second slider 413 are slidably installed inside the connection frame 401. A driven shaft 408 and a driving shaft 407 are respectively rotatably installed inside the first slider 409 and the second slider 413. Transmission rods 410 are fixedly connected to the side walls of the driving shaft 407 and the driven shaft 408. The transmission rod 410 is spliced by a circular rod in the middle and frustum columns at both ends. An ammonia fiber belt 402 is in transmission connection with the side walls of the two transmission rods 410. The chip collection structure 4 further includes a folding cylinder 405; a cleaning structure 5 arranged inside the second slider 413 for cleaning the chips adhered to the surface of the ammonia fiber belt 402; a pressing structure 6 arranged on the side of the operating table 1 for pressing and compressing the folding cylinder 405 and the chips inside. By setting the chip collection structure 4, it facilitates the rapid and effective collection of the metal chips of the product during the turning process above the operating table 1 by means of transmission, avoiding the risks that are easily caused by methods such as the air flow method. It not only facilitates the rapid collection and treatment of the chips during the turning of the metal product on the operating table 1, but also improves the safety performance of clamping the metal product. By setting the cleaning structure 5, it facilitates the sweeping of the metal chips adhered to the surface of the ammonia fiber belt 402 when using coolant during the processing of the metal product, further improving the collection efficiency of the metal chips. By setting the pressing structure 6, it facilitates the stable pressing of the metal chips inside the folding cylinder 405. The loose metal chips are likely to occupy a large space, and there is a phenomenon that the folding cylinder 405 needs to be frequently filled and emptied of the metal chips inside, further improving the collection efficiency of the metal chips.

[0047] Specifically, the following describes the specific settings and functions of its chip collection structure 4, cleaning structure 5 and pressing structure 6.

[0048] As Figures 1 - 6 and Figure 8 as well as Figures 10 - 13As shown, a bidirectional lead screw 406 is rotatably installed inside the connection box 401, and the bidirectional lead screw 406 is threadedly connected to the outer sides of the first slider 409 and the second slider 413. Rotating the bidirectional lead screw 406 can move the first slider 409 and the second slider 413 towards each other. A mounting frame 403 is fixedly installed on the surface of the second slider 413. The mounting frame 403 is composed of an irregular rod and a circular ring spliced together. A motor 411 is fixedly installed on the inner side of the circular ring of the mounting frame 403, and the output end of the motor 411 is fixedly connected to the driving shaft 407. Starting the motor 411, the motor 411 will drive the driving shaft 407 to rotate, thereby realizing the driving work of the spandex tape 402 on the two driving rods 410. A number of columns of barbs 412 are fixedly connected to the side wall of the driving rod 410, and the barbs 412 are arc-shaped structures. By setting the arc-shaped barbs 412 on the side wall of the driving rod 410, the stability of the driving rod 410 during the transmission of the spandex tape 402 is improved, and the phenomenon of the spandex tape 402 slipping off the pulley 63 during the transmission process is avoided. A fixing plate 404 is fixedly installed on the side wall of the operating table 1. The upper port of the fixing plate 404 is communicated with a collecting hopper 414. A rectangular ring 419 is embedded inside the fixing plate 404. Two columns of rotating blocks 415 are rotatably connected to the lower surface of the fixing plate 404. The upper port of the folding cylinder 405 is fixedly connected to the rectangular ring 419, and the lower port of the folding cylinder 405 is fixedly connected to a bottom plate 420. Two rectangular blocks 417 are fixedly installed inside the collecting hopper 414. The lower surfaces of the two rectangular blocks 417 are fixedly connected to telescopic rods 418, and the lower ends of the two telescopic rods 418 are fixedly connected to a triangular prism 416. The residual chips falling inside the hopper will evenly fall inside the folding cylinder 405 along the two inclined surfaces of the triangular prism 416. The setting of the triangular prism 416 realizes the guiding work of the collected metal residual chips and avoids the accumulation of metal residual chips at a single location.

[0049] As Figures 1 - 4 and Figure 5 and Figure 7 as well as Figure 9As shown, a plate 510 is fixedly connected to the side wall of the second slider 413. A connecting rod 505 is rotatably connected inside the plate 510. A central shaft 501 is fixedly connected to the end side of the connecting rod 505. A plurality of brush rods 507 are fixedly connected to the side wall of the central shaft 501. A plurality of bristles 508 are fixedly connected to the side wall of the brush rod 507. Both sides of the brush rod 507 are bent structures. The bristles 508 will have relative movement with the metal debris on the surface of the spandex tape 402, thus facilitating the rapid sweeping off of the wet metal debris adhering to the surface of the spandex tape 402. A third gear 506 is fixedly connected to the side wall of the connecting rod 505. A central rod 503 is rotatably connected inside the plate 510. A second gear 504 is fixedly connected to the side wall of the central rod 503. The tooth surface of the third gear 506 meshes with the tooth surface of the second gear 504. A first gear 502 is fixedly connected to the side wall of the driving shaft 407. The tooth surface of the first gear 502 meshes with the tooth surface of the second gear 504. When the driving shaft 407 rotates, through the transmission of the first gear 502, the second gear 504 and the third gear 506, the connecting rod 505 can be driven to rotate. By using the second gear 504 as an intermediary to drive the central shaft 501 to rotate, the central shaft 501 can drive the brush rod 507 to rotate in the direction opposite to the conveying direction of the spandex tape 402. A comb plate frame 509 is fixedly connected to the side wall of the operating table 1. The comb plate frame 509 is spliced by two rectangular bars and a comb plate with an arc structure. Relative movement will occur between the bristles 508 and the comb plate frame 509 during the rotation process, which can realize the combing work of the metal debris adhering between the bristles 508, avoiding the phenomenon that it is not easy to handle the metal debris adhering between the bristles 508. The scraped metal debris will directly fall into the inside of the hopper for collection.

[0050] As Figures 1 - 2 and Figure 8 and Figures 10 - 11 as well as Figure 13As shown in the figure, the pressing structure 6 includes a jack 69 opened on the lower surface of the bottom plate 420. A positioning block 62 is fixedly connected to the side wall of the fixing plate 404. A limiting frame 64 is slidably connected inside the positioning block 62. A rectangular plate 65 is fixedly connected to the lower end of the limiting frame 64. An insertion frame 61 is slidably connected inside the rectangular plate 65. The size of the insertion frame 61 is adapted to the size of the jack 69. A pulley 63 is rotatably connected inside the positioning block 62. A pull rope 66 is fixedly connected to the upper surface of the rectangular plate 65. The pull rope 66 is located on the side wall of the pulley 63. The other end of the pull rope 66 is fixedly connected to a pressing plate 68. Insert the insertion plate into the inside of the jack 69 on the bottom plate 420. When the metal chips are about to fill the inside of the folding cylinder 405, at this time, the pressing plate 68 can be stepped on. The pressing plate 68 will drive the pull rope 66 to be pulled. During the movement of the pull rope 66, relative movement occurs between the pull rope 66 and the pulley 63, which has the effect of changing the acting direction of the pulling force of the pull rope 66. At this time, the lifting work of the rectangular plate 65, the insertion frame 61 and the bottom plate 420 can be realized. At this time, the folding cylinder 405 will be compressed. Some of the metal chips inside the folding cylinder 405 will squeeze the triangular prism 416 to lift, so as to make the hopper inlet position at the upper port of the fixing plate 404 in a closed state as much as possible, which can improve the leveling and compressing effect of the metal chips inside the folding cylinder 405. There is still space for storing metal chips inside the compressed folding cylinder 405, which further improves the collection efficiency of the metal chips. A support plate 67 is fixedly connected to the side wall of the operating table 1. The pressing plate 68 is slidably connected to the side wall of the support plate 67. By setting the pressing plate 68 to slide inside the support plate 67, it plays a role in restricting the moving direction of the pressing plate 68, which facilitates the stable pressing work in a single direction of the pressing plate 68.

[0051] Working principle: When turning metal products is required, directly place the metal product above the spandex belt 402. At this time, rotate the bidirectional lead screw 406 to move the first slider 409 and the second slider 413 towards each other until the spandex belt 402 is in a relatively loose position. At this time, the six-jaw chuck 3 can be driven to perform stable clamping work on the metal product. By setting the spandex belt 402 above the six-jaw chuck 3, it not only avoids the phenomenon that metal chips falling into the gap between the six-jaw chuck 3 and the operating table 1 during the processing process easily causes blockage during the operation of the six-jaw chuck 3, but also sets the spandex belt 402 between the metal product and the six-jaw chuck 3, avoiding the phenomenon that the six-jaw chuck 3 directly clamping the metal product causes damage to the outer surface of the metal product. After the processing of the product is completed, after removing the metal product, most of the metal chips generated during the turning of the metal product will fall above the spandex belt 402. At this time, rotate the bidirectional lead screw 406 again to move the bidirectional lead screw 406 towards the side away from each other, so that the spandex belt 402 is in a tensioned state. Then start the motor 411, and the motor 411 will drive the driving shaft 407 to rotate, thereby realizing the transmission work of the spandex belt 402 on the two transmission rods 410. By setting the barbs 412 on the side wall arc structure of the transmission rod 410, the stability of the transmission rod 410 during the transmission of the spandex belt 402 is improved, avoiding the phenomenon of the spandex belt 402 slipping like a pulley 63 during the transmission process. By setting the transmission rod 410 with a frustum-shaped column structure at both ends, the phenomenon that metal chips fall from both sides during the transmission process can be effectively avoided, and this can make the spandex belt 402 tend to a structure that bends inward more, which is beneficial to the work of placing and clamping the metal product when the spandex belt 402 is in a loose structure state. Before collecting the metal chips, first embed the rectangular ring 419 under the fixed plate 404, and then rotate the rotating blocks 415 arranged on both sides to realize the rapid installation work of the rectangular ring 419. During the transmission of the spandex belt 402, the chips will first fall into the inner side of the hopper for preliminary collection work, and then the chips falling into the inner side of the hopper will evenly fall into the inner side of the folding cylinder 405 along the two inclined surfaces of the triangular prism 416. The setting of the triangular prism 416 realizes the guiding work of the collected metal chips, avoiding the accumulation of metal chips at a single position and improving the collection efficiency of the metal chips. By setting the structure between the two transmission rods 410 to be flexible and relatively movable, it not only facilitates the clamping work of the metal product on the spandex belt 402 by the six-jaw chuck 3, but also facilitates the subsequent regular replacement work of the spandex belt 402. By setting the spandex belt 402 made of spandex material, firstly, the spandex material has good elastic properties, which facilitates the normal clamping work of the metal product by the six-jaw chuck 3. Secondly, the fiber surface of the spandex itself is relatively smooth, without obvious pores or rough surfaces, and iron chips are not easy to adhere to its surface.Moreover, spandex generally has no static electricity or a weak static electricity effect, and will not adsorb iron filings due to electrostatic attraction, improving the transfer and collection effect of metal iron filings. By setting up the chip collection structure 4, it facilitates the rapid and effective collection of metal scraps during the turning process above the operating table 1 through the transfer method, avoiding the risks easily caused by methods such as the air flow method. It not only facilitates the rapid collection and processing of scraps during the turning of metal products on the operating table 1, but also improves the safety performance of clamping metal products.

[0052] When using coolant during the processing of metal products, metal scraps are likely to adhere to the surface of the spandex belt 402. During the startup of the motor 411, when the driving shaft 407 rotates, through the transmission of the first gear 502, the second gear 504, and the third gear 506, the connecting rod 505 can be driven to rotate. By setting the second gear 504 as an intermediary to drive the central shaft 501 to rotate, the central shaft 501 can drive the brush rod 507 to rotate in the direction opposite to the transmission direction of the spandex belt 402. The bristles 508 will have relative movement with the metal scraps on the surface of the spandex belt 402, thus facilitating the rapid sweeping off of the wet metal scraps adhering to the surface of the spandex belt 402, further improving the cleaning efficiency of the metal scraps adhering to the spandex belt 402. The bent structures on both sides of the brush rod 507 can better fit the surface of the spandex belt 402, improving the cleaning effect. During the process of cleaning metal scraps, the bristles 508 will have relative movement with the comb plate frame 509 during rotation, enabling the combing of the metal scraps adhering between the bristles 508 and avoiding the phenomenon that it is difficult to handle the metal scraps adhering between the bristles 508. The scraped-off metal scraps will directly fall into the inner side of the hopper for collection. By setting up the cleaning structure 5, it facilitates the sweeping off of the metal scraps adhering to the surface of the spandex belt 402 when using coolant during the processing of metal products, further improving the collection efficiency of metal scraps.

[0053] During the initial process of collecting metal scraps, most of the metal scraps are in a loose state. First, insert the plug board into the inner side of the jack 69 on the bottom plate 420. When the inner side of the folding cylinder 405 is almost full of metal scraps, the pressing plate 68 can be stepped on at this time. The pressing plate 68 will drive the pulling rope 66 to twitch. During the movement of the pulling rope 66, relative movement occurs between the pulling rope 66 and the pulley 63, which has the effect of changing the acting direction of the pulling force of the pulling rope 66. At this time, the lifting work of the rectangular plate 65, the insertion frame 61, and the bottom plate 420 can be realized. At this time, the folding cylinder 405 will be compressed, and some of the metal scraps inside the folding cylinder 405 will squeeze the triangular prism 416 to lift, and try to keep the hopper inlet position at the upper port of the fixed plate 404 in a closed state, which can improve the leveling and compression effect of the metal scraps inside the folding cylinder 405. There will still be space for storing metal scraps inside the compressed folding cylinder 405, which further improves the collection efficiency of the metal scraps. By setting the pressing plate 68 to slide inside the support plate 67, it plays a role in restricting the moving direction of the pressing plate 68, facilitating the stable pressing work in a single direction of the pressing plate 68. The sliding of the limiting frame 64 inside the positioning block 62 plays a role in restricting the moving direction of the rectangular plate 65, facilitating the restriction work of the lifting direction of the bottom plate 420, and improving the compression effect of the metal scraps inside the folding cylinder 405. By setting the pressing structure 6, it facilitates the stable pressing work of the metal scraps inside the folding cylinder 405. The loose-structured metal scraps are likely to occupy a large space, and it is necessary to frequently fill and pour the metal scraps inside the folding cylinder 405, which further improves the collection efficiency of the metal scraps.
