A metal cutting chip recycling device

Abstract

This invention discloses a metal cutting waste recycling device, including a compression tank. A drive rod and an adjustment assembly are installed inside the compression tank. Multiple compression plates are arranged circumferentially on the drive rod. The adjustment assembly is used to adjust at least one compression plate to deflect upwards. The drive rod, along with the compression plates, compresses the metal waste in the compression tank. When there are difficult-to-compress bulk metal scraps in the compression tank, the adjustment mechanism adjusts the corresponding compression plate so that it deflects upwards when in contact with the bulk metal scrap. This avoids rigid contact between the compression plate and the bulk metal scrap, preventing localized stress concentration at the contact point and potential damage to the compression plate.

Description

Technical Field

[0001] This invention relates to the field of metal waste treatment, and more specifically to a device for recycling metal cutting chips. Background Technology

[0002] Metal cutting is a method of processing metal materials using cutting tools. In the metal cutting process, the cutting tool contacts the metal material in a rotating or linear motion and removes the metal material through cutting force, thereby forming the metal material into the desired shape and size. Metal cutting is a common metal processing method, widely used in manufacturing industries such as parts processing, mold making, and machining. Common metal cutting processes include turning, milling, drilling, and boring.

[0003] For example, patent CN112246836A, published on January 22, 2021, discloses a metal cutting shavings recycling device, including a device housing. A feed inlet is fixedly connected to the upper end wall of the device housing, and a feed pipe is fixedly connected to the lower end face of the feed inlet. A filter box is fixedly connected to the lower end face of the feed pipe. The filter box contains a filter chamber with a screening device. A crushing box contains a crushing chamber with a crushing device. A moving chamber is fixedly connected to the upper end wall of the device housing with an auxiliary device. A forming chamber is fixedly connected to the lower end wall of the device housing with a pressing device. This metal cutting shavings recycling device can recycle iron filings generated during cutting, reducing space occupation and fully recycling resources, resulting in high efficiency.

[0004] When processing existing metal materials, a large amount of metal waste is generated. This metal waste mainly includes independent block metal waste that is difficult to compress and easily compressible shaving metal waste. Shaving metal waste occupies a large space. In order to facilitate the transportation of metal waste, it is necessary to compress it. When there are block metal wastes that are difficult to compress in the metal waste being compressed, it is very easy to cause local stress concentration in the compression mechanism, which can lead to damage. Summary of the Invention

[0005] The purpose of this invention is to provide a metal cutting chip recycling device to solve the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A metal cutting shavings recycling device includes a compression tank, a drive rod and an adjustment component are provided inside the compression tank, a plurality of compression plates are arranged along the circumference of the drive rod, and the adjustment component is used to adjust at least one compression plate to deflect upward.

[0008] As mentioned above, the top of the compression tank is open, and multiple filter grooves are evenly provided on the side wall of the compression tank. All filter grooves are connected to the interior of the compression tank and are spaced apart along the circumference of the compression tank.

[0009] As described above, the drive rod includes a drive unit and a rod body. The drive unit drives the rod body to move toward the bottom of the compression tank, and the compression plate is located at the end of the rod body away from the drive unit.

[0010] As described above, the rod body is divided into a connecting section and a pressing section. One end of the connecting section is fixedly connected to the driving unit, and a groove is opened on the other end face of the connecting section. A sliding cylinder is slidably installed in the groove, and the sliding cylinder and the groove are connected by a traction spring. A connecting rod is fixedly installed on one end of the pressing section. The connecting rod is inserted into the groove, and the other end of the connecting rod is rotatably connected to the sliding cylinder by a return torsion spring. The adjusting component includes a hinge block, which is fixedly installed on the other end of the pressing section. Multiple compression plates are installed on the side wall of the hinge block. Wedges that cooperate with each other are installed on the adjacent end faces of the connecting section and the pressing section.

[0011] The connecting section and the extrusion section, as described above, exist in the following two states:

[0012] One feature is that the connecting section and the extrusion section are spaced apart, and the traction spring is in a naturally extended state.

[0013] Secondly, the connecting section and the extrusion section are closely fitted together, and the traction spring is in a compressed state.

[0014] As described above, the side wall of the hinge block is provided with multiple connecting grooves, each corresponding to a compression plate. The compression plate is rotatably installed in the connecting groove via a rotating shaft. An extension support block is fixedly installed on the side of the rotating shaft near the shaft body. The extension support block is connected to the connecting groove via a limiting spring. The limiting spring is used to limit the compression plate from deflecting toward the opening of the compression tank.

[0015] As mentioned above, a limiting component is also provided in the through groove. The limiting component includes a connecting rod. One end of the connecting rod is hinged to the extension support block. The other end of the connecting rod is inserted into the interior of the extrusion section. A V-shaped frame is hinged to the other end of the connecting rod. The other end of the connecting rod is hinged to the top of one side of the V-shaped frame. The bottom end of the V-shaped frame is rotatably mounted on the inner wall of the extrusion section. A limiting block is fixedly installed on the top section of the other side of the V-shaped frame. Part of the limiting block passes through the through groove and is located outside the extrusion section of the rod body.

[0016] The aforementioned adjustment assembly also includes a coordinating part, which includes a collar. The collar is located on the side wall of the extrusion section. The upper end face of the collar is connected to the upper end of the extrusion section via a tension spring. The lower end face of the collar is fixedly connected to the hinge block via a traction rod. A limit rod is also installed on the side wall of the extrusion section. A positioning hole that matches the rod is provided on the extension block. When the hinge block moves upward, the rod is inserted into the positioning hole.

[0017] As mentioned above, a top block is also fixedly installed at the bottom of the hinge block. The bottom surface of the top block is closer to the bottom of the compression tank than the bottom surface of the compression plate. The bottom end of the top block is inclined, and multiple freely rolling balls are installed on the inclined surface of the top block.

[0018] As mentioned above, multiple material feeding strips are evenly arranged on the surface of the compression plate away from the opening of the compression tank, and the multiple material feeding strips are arranged at intervals along the circumference of the compression plate.

[0019] The beneficial effects of the present invention are as follows: In the above technical solution, the adjustment component provided by the present invention drives the main rod to compress the metal scrap in the compression box with the compression plate. When there is a block of metal scrap that is difficult to compress in the compression box, the adjustment mechanism adjusts the corresponding compression plate so that the compression plate will deflect upward when it comes into contact with the block of metal scrap. This avoids rigid contact between the compression plate and the block of metal scrap, which would cause local stress concentration at the contact point between the compression plate and the block of metal scrap, resulting in damage to the compression plate.

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 - Appendix Figure 10 The present invention will be described in further detail below.

[0034] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] The present invention provides a metal cutting shavings recycling device, including a compression tank 1, which is placed vertically and has an open top. The compression tank 1 is provided with a drive rod 2 and an adjustment component 3. Multiple compression plates 4 are arranged on the drive rod 2 along its circumference. The drive rod 2 drives the compression plates 4 to move vertically toward the bottom of the compression tank 1. The adjustment component 3 is used to adjust at least one compression plate 4 to deflect upward.

[0036] Specifically, manual or mechanical equipment collects the metal scrap generated from metal cutting. This metal scrap mainly includes two types: one is blocky metal scrap, which is difficult to compress; the other is curled metal chips, which are easier to compress due to their larger space-consuming nature. The collected metal scrap is then poured into the compression tank 1. At this time, the drive rod 2 moves the compression plate 4 towards the bottom of the compression tank 1. When the compression plate 4 comes into contact with the metal scrap, it mainly exists in the following two states:

[0037] One scenario is that when the curled metal chips completely envelop the blocky metal scrap (or the blocky metal scrap is covered by the curled metal chips, and the thickness of the curled metal chip covering the blocky metal scrap is relatively thick, so that the compression plate 4 never comes into contact with the blocky metal scrap as the curled metal chips deform), as the compression plate 4 moves downward, the surface of the compression plate 4 mainly comes into contact with the curled metal chips. As a result, the bottom of the compression plate 4 squeezes the metal scrap inside the compression tank 1. As the curled metal chips deform, they envelop the blocky metal scrap, preventing the blocky metal scrap from directly contacting the surface of the compression plate 4. This prevents the blocky metal scrap from squeezing the surface of the compression plate 4 during metal scrap compression, thus avoiding local stress concentration on the surface of the compression plate 4 and subsequent damage to the compression plate 4.

[0038] Secondly, when the bulky metal scrap is located on top of the curled metal chips, that is, as the compression plate 4 moves downward, the compression plate 4 above the bulky metal scrap mainly contacts the bulky metal scrap. Therefore, as the compression plate 4 continues to move downward, the force exerted by the bulky metal scrap on the compression plate 4 increases, especially when multiple bulky metal scraps sequentially abut against each other in the vertical direction. Preferably, a pressure sensor is installed on each compression plate 4. The pressure sensor is electrically connected to the adjustment component 3. When the pressure sensor detects an abnormality where the force on that compression plate 4 is much greater than the force on other compression plates 4, the pressure sensor sends a signal to the adjustment component 3. The pressure sensor monitors the pressure received, which is existing technology and will not be described in detail here. In this embodiment, the adjustment component 3 includes a winding motor and a traction rope. One end of the traction rope is connected to the winding motor, and the other end of the traction rope is connected to the end of the compression plate 4 away from the rod 22. As the winding motor winds the traction rope, the traction rope causes the compression plate 4 to deflect upward, reducing the pressure when the compression plate 4 comes into contact with the block metal scrap. This prevents the block metal scrap from causing local stress concentration on the surface of the compression plate 4 when the block metal scrap and the compression plate 4 are squeezed together, which could lead to damage to the compression plate 4.

[0039] In summary, the compression treatment of metal scrap inside the compression tank 1 is achieved, which transforms the originally curled metal chips into a compressed and aggregated state, thereby improving the space utilization rate of the metal scrap and making the metal scrap more convenient to transport.

[0040] To facilitate the removal of the compressed metal block from the compression tank 1, a lifting assembly is installed at the bottom of the compression tank 1. The lifting assembly includes a hydraulic telescopic rod and a lifting platform. The lifting platform is placed at the bottom of the compression tank 1. The hydraulic telescopic rod drives the lifting platform to move vertically upward. Specifically, after the metal scrap is compressed, the hydraulic telescopic rod drives the lifting platform to move vertically upward, and the lifting platform pushes the compressed metal block away from the compression tank 1, completing the removal of the compressed metal block from the compression tank 1.

[0041] When metals are cut, a coolant is often sprayed onto them. The coolant is usually in liquid form, and thus, coolant residue is often left in the collected metal scrap. In order to avoid the coolant affecting the subsequent recycling of metal materials, preferably, multiple filter grooves 5 are evenly provided on the side wall of the compression tank 1. The multiple filter grooves 5 are all connected to the interior of the compression tank 1 and are spaced apart along the circumference of the compression tank 1.

[0042] Specifically, under the squeezing action of the compression plate 4, the metal scrap deforms, and the gaps between the metal scrap become smaller. Under the pressure, the coolant flows out of the filter tank 5 into the compression tank 1, thereby achieving the purpose of removing the coolant from the metal scrap. It should be noted that the squeezing action of the compression plate 4 cannot remove all the coolant from the metal scrap; it can only reduce the coolant content in the metal scrap as much as possible.

[0043] The cut metal scrap pieces come in various shapes (such as cubes, cuboids, spheres, or irregular three-dimensional shapes). Among these diverse shapes, there are always some pieces with inconsistent lengths, widths, and heights (using a cuboid as an example in this embodiment). Consequently, when the metal scrap pieces are cuboids, their heights inside the compression tank 1 vary depending on their placement. Specifically, when the metal scrap pieces are placed vertically, their height inside the compression tank 1 is the highest. At this time, the compression plate 4 on top of the metal scrap pieces makes early contact with them, thus preventing mutual compression between the metal scrap pieces and the compression plate 4, which could lead to damage to the compression plate 4 and the metal scrap pieces. When stress concentration occurs at the contact point with the bulk metal scrap, damaging the compression plate 4, the adjusting component 3 prematurely deflects the compression plate 4 upwards to reduce the pressure when the compression plate 4 contacts the bulk metal scrap. At this time, the lower, curled metal chip edge cannot be properly compressed, and the lower, curled metal chip remains loose. In another embodiment of the invention, the driving rod 2 includes a driving part 21 and a rod body 22. In this embodiment, the driving part 21 is a linear telescopic rod, and the telescopic end of the linear telescopic rod is coaxially connected to the rod body 22. The linear telescopic rod drives the rod body 22 to move towards the bottom of the compression tank 1. The compression plate 4 is located at the end of the rod body 22 away from the driving part 21. The rod body 22 is divided into a connecting section 22. 1. The extrusion section 222 and the connecting section 221 are fixedly connected at one end to the drive unit 21. A groove 223 is formed on the other end face of the connecting section 221. A slide cylinder 224 is slidably installed in the groove 223. The slide cylinder 224 and the groove 223 are connected by a traction spring 225. A connecting rod 226 is formed at one end of the extrusion section 222. The connecting rod 226 is inserted into the groove 223. The other end of the connecting rod 226 is fitted into the slide cylinder 224. The slide cylinder 224 can rotate relative to the connecting rod 226. At the same time, the connecting rod 226 and the slide cylinder 224 are also connected by a return torsion spring (not shown in the figure). That is, the extrusion section 222 is suspended on the bottom surface of the connecting section 221 by the connecting rod 226. The adjustment component 3 includes a hinge block 31. The hinge block 31 is fixedly installed at the other end of the extrusion section 222. Multiple connecting grooves 311 are provided on the side wall of the hinge block 31, each corresponding to a compression plate 4. The compression plate 4 is rotatably installed in the connecting groove 311 via a rotating shaft 41. An extension support block 42 is fixedly installed on the side wall of the rotating shaft 41 near the shaft 22. The extension support block 42 is connected to the connecting groove 311 via a limiting spring 43, which limits the compression plate 4 from deflecting towards the opening of the compression tank 1. Multiple compression plates 4 are rotatably installed on the hinge block 31 via the rotating shaft 41 and torsion springs. Multiple material-pushing strips 7 are evenly arranged on the surface of the compression plate 4 away from the opening of the compression tank 1, spaced apart circumferentially along the compression plate 4.The connecting section 221 and the extrusion section 222 have mating wedges 227 installed on their adjacent end faces. Initially, before compression, the two wedges 227 on the adjacent end faces of the connecting section 221 and the extrusion section 222 are far apart, meaning there is a gap between them. At this time, the traction spring 225 is in its natural extension state. When the lower end face of the compression plate 4 is pressed against by scrap metal, as the linear telescopic rod continues to extend, the traction spring 225 is gradually compressed, meaning the connecting section 221 and the extrusion section 222 move closer together. The two wedges 227 on the adjacent end faces of the connecting section 221 and the extrusion section 222 press and move closer together. Under the wedge-shaped engagement of the two wedges 227, the extrusion section 222 rotates relative to the connecting section 221 around its axis by a certain amplitude. The extrusion section 222 synchronously drives the compression plate 4 to rotate.

[0044] Specifically, when the elongated metal scrap inside the compression tank 1 is placed vertically, the telescopic rod drive rod 22 moves the compression plate 4 towards the bottom of the compression tank 1. When the bottom surface of the compression plate 4 contacts the vertically placed block of metal scrap, the block of metal scrap presses against the compression plate 4, preventing the compression plate 4 from continuing to move downwards and compress the metal scrap inside the compression tank 1. At this time, as the linear telescopic rod continues to extend, the traction spring 225 connecting the connecting section 221 and the compression section 222 gradually contracts. The contracted traction spring 225 accumulates elastic potential energy. At this time, the connecting section 221 and the compression section 222... The wedges 227 on the near end faces of the extrusion section 222 approach each other. Under the action of the wedges 227 on the near end faces of the connecting section 221 and the extrusion section 222, the lower extrusion section 222 rotates around its own axis. At this time, the extrusion section 222 rotates relative to the slide cylinder 224. As the extrusion section 222 rotates, the extrusion section 222 also rotates synchronously with the compression plate 4. When the compression plate 4 rotates, the feeding strips 7 on the surface of the compression plate 4 push the (vertically placed) block of metal scrap to one side, thus turning the block of metal scrap that was originally in a vertical state into a vertical state. In the tilted state, as the linear telescopic rod continues to extend, the compression plate 4 continues to squeeze the top of the tilted block of metal, driving the tilted block of metal to continue to deflect towards the horizontal plane, making the already tilted block of metal even more tilted, further reducing the influence of the height of the block of metal scrap on the degree of compression of the metal scrap, and improving the compression ratio of the metal scrap. Finally, the linear telescopic rod drives the rod body 22 away from the bottom of the compression tank 1 and moves towards the opening of the compression tank 1 until the compression plate 4 leaves the compression tank 1. After the compression plate 4 separates from the metal scrap, the compression... When the lower end of the shrink plate 4 loses the support of the metal scrap, the traction spring 225 releases the accumulated elastic potential energy. The traction spring 225 pushes the slide cylinder 224 to move downward. The slide cylinder 224, along with the extrusion section 222, also moves downward (that is, away from the connecting section 221). As the connecting section 221 and the extrusion section 222 move away from each other, the wedges 227 on the connecting section 221 and the extrusion section 222 also move away from each other. As a result, the extrusion section 222 located below returns to its initial state under the action of the reset torsion spring, making it convenient to compress the vertical block of metal scrap next time.

[0045] It should be noted that when the vertically placed block of metal scrap is directly below the rod 22, the rod 22 will not drive the vertically placed block of metal scrap to deflect. Consequently, the block of metal scrap below the rod 22 will prevent the compression plate 4 from moving down normally to compress the metal scrap inside the compression tank 1, thus affecting the normal compression of the metal scrap inside the compression tank 1. In this embodiment, preferably, a top block 6 is also fixedly installed at the bottom end of the hinge block 31. The top block 6 is arranged in an inverted cone shape. The bottom surface of the top block 6 is closer to the bottom of the compression tank 1 than the bottom surface of the compression plate 4. Furthermore, the bottom end of the top block 6 is inclined. Multiple freely rolling balls are installed on the inclined surface of the top block 6.

[0046] Specifically, when there is a vertically placed block of metal scrap directly below the rod 22, as the linear telescopic rod moves the rod 22 downwards, the inclined surface of the top block 6 at the bottom of the hinge block 31 contacts the vertically placed block of metal scrap first. When the inclined surface of the top block 6 contacts the block of metal scrap, as the top block 6 moves downwards, the block of metal scrap moves along the inclined surface of the top block 6, which makes the originally vertical block of metal scrap tilted. Subsequently, compression is performed. It should also be noted that the lowest point of the top block 6 is at the same height as the top point of the feeding bar 7.

[0047] It should be noted that the resistance experienced by the compression plate 4 is positively correlated with the degree of compression of the metal scrap. That is, the greater the degree of compression of the metal scrap, the greater the resistance experienced by the compression plate 4. Consequently, when the metal scrap is compressed to a certain extent, the resistance experienced by the compression plate 4 becomes too great. However, because the surface of the compression plate 4 is in contact with the relatively flat metal scrap at this point, stress concentration will not occur on the surface of the compression plate 4, preventing damage to the compression plate 4. Therefore, in order to improve the compression rate of the metal scrap, it is necessary to continue compressing the metal scrap. In this embodiment, a top block 6 is provided below the hinge block 31. As the linear telescopic rod continues to work, the rod 22 continues to push the top block 6 downward. When the rod 22 moves downward, the metal scrap with greater resistance... This will push the compression plate 4 to deflect upwards, causing the initially horizontal compression plate 4 to become tilted. Consequently, the tilted compression plate 4 makes it difficult to compress the metal scrap inside the compression tank 1 more evenly. Therefore, in another embodiment of the invention, the extrusion section 222 of the rod 22 is hollow, and its lower end is open. Multiple through slots 228 are provided on the side wall of the extrusion section 222, connecting the inner cavity of the extrusion section 222 to the inner cavity of the compression tank 1. The hinge block 31 is slidably installed inside the extrusion section 222, and its top end is connected to the extrusion section 222 by a support spring 314. The top block 6, located at the bottom end of the hinge block 31, passes through the inner cavity of the extrusion section 222, meaning the top block 6 is located inside the compression tank 1. The hinge block 31 includes a main body 312 and multiple branch blocks 313. The main body 312 is vertically swaying and installed inside the extrusion section 222. The multiple branch blocks 313 are spaced apart circumferentially along the main body 312 and are fixedly connected to the main body 312. Each branch block 313 corresponds to a multiple through slot 228, and one end of each branch block 313 passes through the through slot 228 and is located inside the compression tank 1. A connecting slot 311 is formed on the branch block 313. Each through slot 228 corresponds to a multiple compression plate 4. A limiting member 32 is also provided in the through slot 228. The limiting member 32 includes a connecting rod 321. One end of the connecting rod 321 is hinged to the extension support block 42, and the other end of the connecting rod 321 is inserted into the extension support block 42. Inside the extrusion section 222, the other end of the connecting rod 321 is hinged to a V-shaped frame 322. Because the V-shaped frame 322 has a V-shaped structure, in this embodiment, it has one bottom point and two top points. The other end of the connecting rod 321 is hinged to one top point of the V-shaped frame 322. The bottom point of the V-shaped frame 322 is rotatably mounted on the inner wall of the extrusion section 222. A limiting block 323 is fixedly mounted on the top section of the other side of the V-shaped frame 322. In this embodiment, the openings of the multiple V-shaped frames 322 are all positioned opposite each other towards the inner wall of the compression tank 1. A portion of the limiting block 323 passes through the through groove 228 and is located outside the extrusion section 222 of the rod 22. The adjustment assembly 3 also includes a cooperating part 33, which includes a collar 331.A collar 331 is fitted onto the outer wall of the extrusion section 222. The upper end face of the collar 331 is connected to the upper end of the extrusion section 222 via a tension spring 332, and the lower end face of the collar 331 is fixedly connected to the hinge block 31 via a traction rod 333. In the initial state, the collar 331 is located below the limiting block 323. At this time, the tension spring 332 is in a stretched state, accumulating elastic potential energy. Multiple limiting blocks 323 are spaced apart along the circumference of the collar 331, and all of the limiting blocks 323 are used to prevent the collar 331 from moving upward. A rod 229 and an electrically controlled telescopic rod for resetting are also installed on the side wall of the extrusion section 222. The extension support block 42 has a positioning hole 44 that matches the rod 229. When the hinge block 31 moves upward, the rod 229 is inserted into the positioning hole 44.

[0048] Specifically, when the metal scrap is compressed to a certain extent, the resistance experienced by the compression plate 4 becomes too great. A top block 6 is located below the hinge block 31. As the linear telescopic rod continues to operate, the rod 22 continues to push the top block 6 downwards, creating a concave center and a convex periphery. As the rod 22 continues to move downwards, the metal scrap with greater resistance in the convex periphery pushes the compression plate 4 upwards, causing the initially horizontal compression plate 4 to tilt. When all the compression plates 4 are tilted, that is, when the compression plate 4 rotates from its initial horizontal state to its current tilted state, this... The compression plate 4 rotates inside the connecting groove 311 via the rotating shaft 41, and the torsion spring connected to the compression plate 4 deforms and accumulates elastic potential energy. Because the end of the compression plate 4 away from the rod 22 deflects upward, the extension block 42 on the side wall of the rotating shaft 41 near the rod 22 rotates downward. At this time, the limiting spring 43 deforms and accumulates elastic potential energy, so the extension block 42 synchronously pulls the connecting rod 321 downward. As the connecting rod 321 moves downward, the connecting rod 321 carries the V-shaped frame 322 downward. Because the bottom point of the V-shaped frame 322 is rotated and installed on the inner wall of the extrusion section 222, the V-shaped frame 322 rotates around its bottom point. As the rod rotates, the V-shaped frame 322, along with the limiting block 323, rotates downwards. The limiting block 323 is completely retracted into the interior of the rod 22, thus freeing the collar 331 from the constraint of the limiting block 323. The pull spring 332 releases its accumulated elastic potential energy, pulling the collar 331 upwards along the outer wall of the rod 22. As the collar 331 moves upwards, under the action of the traction rod 333, the collar 331 pulls the hinge block 31 upwards synchronously, thereby causing the compression plate 4 to detach from the surface of the metal scrap. At this time, the torsion spring connected to the compression plate 4 releases its accumulated elastic potential energy, causing the compression plate 4 to return to a horizontal state. Furthermore, as the hinge block 31 moves upwards, the compression section... The insert rod 229 on the side wall of 222 is inserted into the positioning hole 44 to prevent the compression plate 4 from tilting when it compresses the metal scrap, thus further improving the compression efficiency of the compression plate 4 on the metal scrap. When reset is required, the electric telescopic rod pushes the collar 331 down, and the collar 331 moves down synchronously with the hinge block 31. As the collar 331 moves down, it pushes the V-shaped frame 322 to rotate downward, and the V-shaped frame 322 moves down synchronously with the limit block 323. After the collar 331 has finished moving down, the V-shaped frame 322 is reset under the action of the torsion spring, and the limit block 323 is locked above the collar 331 again.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
