Description

Technical Field

[0001] This utility model relates to a copper plate cutting device, and more particularly to a copper plate cutting device. Background Technology

[0002] In the copper plate processing industry, especially in production processes such as copper plate slitting or cutting to length, cutting devices are typically used to cut continuously conveyed copper plates to a fixed length and then stack them orderly in a supporting area below. This type of cutting equipment is widely used in the power, electronics, and metal processing industries, characterized by high processing efficiency and strict precision requirements. To achieve automatic stacking after cutting, the cut copper plates typically slide down to a pre-set support platform or stacking area by gravity, forming a stack of copper plates that can be transported or further processed.

[0003] Existing copper plate cutting equipment generally includes a cutting body, a cutting mechanism, a feeding channel, and a receiving plate for receiving the copper plates. After the cutting mechanism completes the segmented cutting of the copper plates, the cut copper plates fall freely through the feeding channel and slide through an inclined unloading plate into the receiving area. To ensure the smooth sliding of the copper plates, the unloading plate is usually set to form a fixed angle with the horizontal plane.

[0004] However, as the number of cuts increases, the copper plates on the support plate gradually stack up. The fixed angle may cause subsequent copper plates to fail to slide accurately to the top of the stack, or even cause interruptions, jamming, or misalignment, thus affecting the neatness of the stack and the operating efficiency of the equipment. Therefore, there is an urgent need to propose a new copper plate cutting device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a copper plate cutting device that overcomes the problems of subsequent copper plates being cut failing to accurately slide to the top of the stack, resulting in slippage deviation and jamming, which in turn affects the neatness of the stack and the cutting efficiency.

[0007] The cutting body includes a cutting opening and a feeding opening, wherein the cutting opening is located upstream in the copper plate conveying direction, and the feeding opening is located downstream in the copper plate conveying direction. The cutting body also includes:

[0008] A cutting mechanism is provided at the cutting opening to cut the copper plate passing through the cutting opening;

[0009] A material unloading mechanism is disposed at the material discharge port of the cutting body, and the material unloading mechanism includes:

[0010] The unloading plate is rotatably connected to the cutting mechanism, and the unloading plate is located between the cutting opening and the ground;

[0013] The unloading plate is configured such that after the copper plate being cut falls onto the support plate, as the stacking height of the copper plates being cut on the support plate increases, the unloading plate is slowly swung upward around its rotational connection point with the cutting mechanism through the controlled extension of the telescopic end, so that the angle between the unloading plate and the horizontal plane gradually decreases, and the copper plates to be cut subsequently slide to the top of the stacked copper plates on the support plate.

[0014] Preferably, the unloading mechanism further includes an adaptive component, comprising:

[0015] A fixing tube, one end of which is rotatably connected to the cutting body;

[0018] Preferably, the unloading plate has a receiving groove on the side away from the cutting body.

[0019] The unloading mechanism also includes:

[0020] An extension plate is disposed within the receiving groove, and the extension plate is moved in a controlled manner such that one end of the extension plate away from the cutting body moves toward or away from the cutting body.

[0021] Preferably, the extension plate has linear grooves on the side away from the cut.

[0022] The unloading plate has a linear groove on the side facing the ground that communicates with the receiving groove, and the linear groove is arranged opposite to the linear toothed groove on the extension plate located in the receiving groove.

[0023] The unloading mechanism also includes:

[0025] A gear is fixedly sleeved on the rotating shaft, and the gear passes through the linear groove and meshes with the linear tooth groove;

[0026] A driver, including a drive shaft that is controlled to rotate;

[0027] A transmission assembly is provided, wherein the drive shaft is connected to the rotating shaft via the transmission assembly.

[0028] Preferably, the side of the unloading plate opposite to the cutting body is constructed with an arc-shaped chamfer.

[0029] Preferably, a guide groove is provided on one side of the inner wall of the receiving groove, and a guide member is provided on the extension plate. The guide member is slidably disposed in the guide groove so that the extension plate can move along the extension direction of the guide groove. The extension direction of the guide groove is parallel to the direction from the side of the unloading plate near the cutting body to the side of the unloading plate away from the cutting body.

[0030] Preferably, the unloading mechanism further includes:

[0031] The fixing base is connected to the cutting body;

[0032] A fixed shaft is connected to the unloading plate;

[0033] A connecting rod, one end of which is rotatably connected to the fixed base, and the other end of which is rotatably connected to the fixed shaft.

[0034] The beneficial effects of the embodiments of this utility model are as follows:

[0035] By employing a rotating connection structure between the unloading plate and the telescopic mechanism, and configuring the unloading plate to gradually swing upwards as the stacking height increases after the cut copper plate falls onto the support plate, thereby dynamically reducing its tilt angle, the technical means effectively solves the problems in the existing technology where the copper plate cannot accurately slide to the top of the stack due to the fixed angle of the unloading plate, resulting in interrupted sliding, uneven stacking, and reduced efficiency. This achieves the technical effects of smooth unloading, neat stacking, and high system continuity during the automatic stacking of copper plates. Attached Figure Description

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] See Figures 1 to 2 A preferred embodiment of this application discloses a cutting device for processing copper plate material, which is unwound from copper coil and straightened. The copper plate passes through the cutting device under the action of an external conveying device. The cutting device includes a cutting body 10, an unloading mechanism 20, and a receiving plate. The cutting body 10 includes a cutting opening 110 and a discharge opening 120. The cutting opening 110 is located upstream in the copper plate conveying direction, and the discharge opening 120 is located downstream in the copper plate conveying direction. The cutting body 10 also includes a cutting mechanism 130, which is disposed at the cutting opening 110 to cut the copper plate passing through the cutting opening 110. The unloading mechanism 20 is disposed at the discharge opening 120 of the cutting body 10, and the unloading mechanism 20 includes a discharge... The system includes a material plate 210 and a telescopic mechanism 220. The unloading plate 210 is rotatably connected to the cutting mechanism 130 and is located between the cutting opening 110 and the ground. The telescopic mechanism 220 includes a mounting end 221 and a controllable telescopic end 222. The telescopic end 222 moves towards or away from the mounting end 221. The mounting end 221 is rotatably connected to the cutting body 10, and the telescopic end 222 is rotatably connected to the unloading plate 210. A receiving plate is positioned below the unloading plate 210 on the side away from the cutting body 10 to receive the cut copper plate. Furthermore, the unloading plate 210 is configured such that after the copper plate being cut falls onto the support plate, as the stacking height of the copper plates being cut on the support plate increases, the telescopic end 222 extends in a controlled manner, causing the unloading plate 210 to slowly swing upwards around its rotational connection point with the cutting mechanism 130, so that the angle between the unloading plate 210 and the horizontal plane gradually decreases, allowing the subsequently cut copper plates to slide down to the top of the stacked copper plates on the support plate.

[0046] This cutting device has a simple structure and stable operation, and is suitable for continuous automated copper plate cutting and stacking processes. Specifically:

[0047] The cutting device includes a cutting body 10, an unloading mechanism 20, and a receiving plate. The cutting body 10 has a cutting opening 110 and a discharge opening 120 arranged sequentially along the copper plate conveying direction. The cutting opening 110 receives the copper plate fed in by the conveying mechanism, and the discharge opening 120 discharges the cut copper plate. The cutting body 10 also includes a cutting mechanism 130, which is located at the cutting opening 110. Its structure can employ mechanical shearing, servo-controlled shearing, or other components suitable for cutting metal sheets, and is used to complete the disconnection operation after the copper plate reaches a preset position.

[0048] The unloading mechanism 20 is located at the unloading port 120 of the cutting body 10, and its main function is to smoothly guide the cut copper plate into the receiving area. The unloading mechanism 20 includes an unloading plate 210 and a telescopic mechanism 220. The unloading plate 210 is located between the cutting port 110 and the ground, and is arranged in a downward tilt to guide the copper plate to slide down onto the receiving plate below by its own weight. The unloading plate 210 is connected to the cutting mechanism 130 by a hinge, and its tilt angle is adjusted in conjunction with a controlled telescopic mechanism 220. The telescopic mechanism 220 includes a mounting end 221 and a telescopic end 222. The mounting end 221 is fixed to the cutting body 10 by a rotatable connection, while the telescopic end 222 is rotatably connected to the unloading plate 210. The telescopic end 222 can extend or retract relative to the mounting end 221 under controlled conditions, thereby changing the angle between the unloading plate 210 and the horizontal plane.

[0049] The receiving plate is positioned below the unloading plate 210 on the side away from the cutting body 10, and is used to receive and stack the copper plates that slide down from the unloading plate 210. The receiving plate can be a fixed platform to facilitate subsequent transfer or stacking operations. During the cutting process, the unloading plate 210 initially has a large tilt angle to ensure that the copper plates slide down smoothly. As the copper plates gradually stack on the receiving plate to a certain height, the telescopic mechanism 220 begins to extend in a controlled manner, pushing the unloading plate 210 to swing slowly upward, thereby gradually reducing the tilt angle of the unloading plate 210, but always maintaining a certain tilt state to prevent the copper plates from being unable to slide.

[0050] This cutting device is suitable for the cutting and stacking processes in automated copper plate production lines, and is especially suitable for metal processing enterprises that require high stacking neatness and cutting efficiency. The equipment has no special requirements for the installation site, only that there is enough space to accommodate the cutting mechanism 130, the stacking platform and its range of motion. The recommended operating environment is a dry, temperature-appropriate factory floor environment free from strong vibration.

[0051] In other alternative embodiments, the telescopic mechanism 220 can be in the form of an electric cylinder, a pneumatic cylinder, or a servo-driven slide, depending on actual needs. Its control method can be linked with the cutting control system, with a sensor detecting the stacking height on the support plate triggering a control signal in real time to achieve automatic adjustment of the unloading plate 210 angle. Furthermore, the unloading plate 210 can be made of low-friction materials such as wear-resistant stainless steel or chrome-plated steel to improve the stability of the copper plate sliding. The support plate can also be equipped with a buffer mechanism or an automatic transfer device to improve stacking efficiency or achieve automatic transfer.

[0052] In this embodiment, due to the adoption of a rotating connection structure between the cutting mechanism 130, the unloading plate 210 and the telescopic mechanism 220, and the configuration of the unloading plate 210 being driven by the telescopic end 222 to gradually swing upward as the copper plate stacking height increases, and the dynamic reduction of the tilt angle, the problem of the copper plate not being able to accurately slide to the top of the stack due to the fixed angle of the unloading plate 210 in the prior art, resulting in interrupted sliding, uneven stacking and reduced efficiency, is effectively solved. Thus, the technical effect of continuous unloading, neat stacking and stable operation during the automatic cutting and stacking of copper plates is achieved.

[0053] To further improve the stability and compliance of the unloading mechanism 20 during dynamic adjustment, see [reference needed]. Figures 2 to 3 In some embodiments, the unloading mechanism 20 further includes an adaptive component 230, which includes a fixed tube, a spring, and a telescopic rod. One end of the fixed tube is rotatably connected to the cutting body 10. The spring is disposed inside the fixed tube, and one end of the spring abuts against the end of the fixed tube near the cutting body 10. One end of the telescopic rod is inserted into the fixed tube through the end of the fixed tube away from the cutting body 10 and abuts against the other end of the spring.

[0054] The adaptive component 230 provides flexible buffering and adaptive adjustment during the movement of the unloading plate 210 with the telescopic mechanism 220, to prevent the unloading plate 210 from swinging too quickly or generating impact during angle changes, ensuring the stability of the copper plate sliding and the control accuracy of the unloading plate 210's attitude. Specifically:

[0055] The adaptive component 230 includes a fixed tube, a spring, and a telescopic rod. One end of the fixed tube is rotatably connected to the cutting body 10, allowing it to be installed in conjunction with the structure of the cutting body 10. The spring is disposed inside the fixed tube, with one end abutting against the inner wall of the fixed tube near the cutting body 10, providing initial elastic support force. The telescopic rod is inserted into the fixed tube from the end away from the cutting body 10, with its inserted end abutting against the other end of the spring. This allows the telescopic rod to adaptively extend or retract axially under the action of the spring during changes in the angle of the unloading plate 210, forming a flexible support path.

[0056] In practical operation, when the telescopic mechanism 220 extends and drives the unloading plate 210 to gradually swing upward, the telescopic rod in the adaptive component 230 will slowly compress the spring due to the angle change of the unloading plate 210, thereby absorbing part of the torque change brought about by the upward swing of the unloading plate 210 and avoiding instability or vibration of the unloading plate 210 caused by sudden angle adjustment; conversely, during the process of the unloading plate 210 falling back, the spring releases energy and drives the telescopic rod to automatically return to its original position, achieving a smooth recovery, which helps the unloading plate 210 maintain within a reasonable transition angle range.

[0057] This structure has no special requirements for overall installation space and is suitable for the unloading module of most sheet metal cutting equipment. The fixed tube and telescopic rod can be made of stainless steel or corrosion-resistant aluminum alloy, while the internal spring is recommended to be made of carbon steel or alloy spring steel with excellent elastic recovery properties. To enhance service life, a lubricating coating or a low-friction sleeve can be applied between the inner wall of the fixed tube and the surface of the telescopic rod.

[0058] In other alternative embodiments, the adaptive component 230 can also be replaced by an airbag-type elastic support or a magnetoelastic combination structure. Depending on the mass of the unloading plate 210, the frequency of material stacking, and the stacking rhythm, the spring stiffness or telescopic rod stroke parameters can be adjusted to match different working conditions and further improve the flexibility and stability of the unloading control.

[0059] In this embodiment, the adaptive component 230 structure, consisting of a fixed tube, spring, and telescopic rod, is adopted. Through its reasonable connection with the cutting body 10 and the unloading plate 210, the flexible support and buffer adjustment function of the unloading plate 210 during the angle change process is realized. Therefore, the problem of copper plate slippage interruption and unloading loss of control caused by sudden angle change or unstable posture of the unloading plate 210 in the prior art is effectively solved. This results in improved stability of the unloading process, enhanced stacking continuity, and improved equipment operation reliability.

[0060] In some embodiments of this application, considering that the support plate is a fixed structure, when the unloading plate 210 swings around its connection point with the cutting mechanism 130, the end of the unloading plate 210 away from the cutting body 10 will change position in space, especially when the included angle gradually decreases, the distance between the end of the unloading plate 210 and the support plate will also decrease accordingly. This change may cause the cut copper plate to fail to contact the top of the support plate during the sliding process, or cause stacking offset or unstable unloading due to the change in contact position. Therefore, in some embodiments, see Figures 3 to 5The unloading plate 210 has a receiving groove 211 on the side away from the cutting body 10. The unloading mechanism 20 also includes an extension plate 240, which is disposed in the receiving groove 211. The extension plate 240 is moved in a controlled manner, so that the end of the extension plate 240 away from the cutting body 10 moves towards or away from the cutting body 10, so as to dynamically compensate for the change in the length of the unloading plate 210, thereby stabilizing the unloading path.

[0061] Specifically:

[0062] A receiving groove 211 is provided on the side of the unloading plate 210 away from the cutting body 10. The receiving groove 211 is arranged along the length direction of the unloading plate 210 and is used to accommodate a sliding extension plate 240. The extension plate 240 is installed in the receiving groove 211 in a controllable manner such as a slot slide rail, guide pin, or guide sleeve rail. Its sliding direction is arranged along the length axis of the unloading plate 210, which allows the end away from the cutting body 10 to achieve relative displacement during the change of the tilt angle of the unloading plate 210, thereby extending or retracting.

[0063] The movement of the extension plate 240 can be controlled by an electric push rod, cylinder, servo slide, or other form of linear drive mechanism. Alternatively, it can be linked to the swing angle of the unloading plate 210 via the linkage 2110, allowing the extension plate 240 to automatically adjust its extension length. The control system can preset the mapping relationship between the angle of the unloading plate 210 and the position of the extension plate 240, calculate the compensation length in real time based on the current angle, and drive the extension plate 240 to move. This ensures that the end of the unloading plate 210 always maintains a relatively consistent position with the top surface of the stacked copper plates, ensuring a stable and reliable downward path for the copper plates.

[0064] This structure is suitable for fixed material-bearing platform scenarios, especially for situations with limited space and high stacking accuracy requirements. The materials for the receiving groove 211 and the extension plate 240 can be high-strength metals or engineering plastics with low friction coefficients. If necessary, a wear-resistant layer or low-friction coating can be added to their contact surfaces. The width of the extension plate 240 is consistent with that of the unloading plate 210 to prevent the copper plate from getting stuck or deflected when it slips off.

[0065] In other alternative embodiments, the extension plate 240 may also be designed as a spring-loaded telescopic structure, which extends by the sliding force of the copper plate itself. Alternatively, a locking device may be provided to keep the position of the extension plate 240 unchanged at a specific angle to adapt to the specific rhythm of batch cutting tasks.

[0066] In this embodiment, by adopting the structure of the extension plate 240 set in the receiving groove 211 at the end of the unloading plate 210, and by using its controlled movement to compensate for the change in the position of the end of the unloading plate 210 during the swinging process, the problem of copper plate slippage or unstable stacking caused by the change in the distance between the unloading plate 210 and the receiving plate due to the angle adjustment of the unloading plate 210 is effectively solved in the prior art. Thus, the technical effects of stable copper plate unloading path, neat and consistent stacking, and continuous unloading process are achieved.

[0067] In some embodiments, to achieve active drive adjustment of the end extension plate 240 of the unloading plate 210 and further improve the control accuracy and response efficiency of the unloading path, this application introduces a transmission structure based on gear 260 meshing and driver 270 linkage into the extension plate 240 structure. This structure is compact and precise in control, enabling precise adjustment of the linear position of the extension plate 240, and is particularly suitable for unloading conditions with continuous stacking rhythm and high-frequency angle changes. See also Figures 3 to 4 The extension plate 240 has a linear toothed groove 241 on the side away from the cutting opening 110. The unloading plate 210 has a linear groove 212 on the side facing the ground, which communicates with the receiving groove 211, and the linear groove 212 is opposite to the linear toothed groove 241 on the extension plate 240 located in the receiving groove 211. The unloading mechanism 20 also includes a rotating shaft 250, a gear 260, a driver 270, and a transmission assembly 280. The rotating shaft 250 is rotatably connected to the unloading plate 210, and the rotating shaft 250 rotates in a controlled manner. The gear 260 is fixedly sleeved on the rotating shaft 250, and the gear 260 passes through the linear groove 212 and meshes with the linear toothed groove 241. The driver 270 includes a drive shaft that rotates in a controlled manner. The drive shaft is connected to the rotating shaft 250 through the transmission assembly 280.

[0068] Specifically:

[0069] A linear toothed groove 241 is formed on the side of the extension plate 240 away from the cutting opening 110 (the side facing the ground). The linear toothed groove 241 extends along the length of the extension plate 240 and is located in the area corresponding to the lower surface of the unloading plate 210. A linear groove 212 is provided on the side of the unloading plate 210 facing the ground. The linear groove 212 is arranged opposite to (aligned with) the linear toothed groove 241 on the extension plate 240 and is connected to the receiving groove 211, so that the linear toothed groove 241 is exposed on the meshing path of the gear 260.

[0070] To drive the extension plate 240 to move along its length, the unloading mechanism 20 further includes a rotating shaft 250, a gear 260, a driver 270, and a transmission assembly 280. The rotating shaft 250 is rotatably connected to the unloading plate 210 and can rotate under control commands. The gear 260 is fixedly sleeved on the rotating shaft 250 and passes through the linear groove 212 of the unloading plate 210, precisely meshing with the linear tooth groove 241. When the gear 260 rotates, it drives the extension plate 240 within the linear tooth groove 241 to move along its length, thus extending or retracting the extension plate 240.

[0071] The driver 270 is a power device with output torque, which can be a servo motor, stepper motor, or electronically controlled synchronous motor, and its output end is a drive shaft. The drive shaft is connected to the rotating shaft 250 for power transmission through a transmission assembly 280. The transmission assembly 280 may include a coupling, a synchronous belt, a gear set 260, or a transmission sprocket structure, to ensure rotational synchronization and torque transmission efficiency between the driver 270 and the rotating shaft 250.

[0072] In actual operation, when a change in the angle of the unloading plate 210 or a need to adjust the stacking height of the copper plates is detected, the driver 270 starts after receiving a control signal. The drive shaft drives the rotating shaft 250 to rotate through the transmission assembly 280, which in turn drives the gear 260 to rotate. During rotation, the gear 260 meshes with the linear tooth groove 241 of the extension plate 240, thereby driving the extension plate 240 to slide along its length, achieving linear adjustment synchronized with the change in the angle of the unloading plate 210, and ensuring that the unloading end and the receiving plate always maintain the optimal docking position.

[0073] This structure is easy to install and highly adaptable to different spaces. The linear groove 212 and the tooth groove fit precisely, allowing for high repeatability during the movement of the extension plate 240. It is suitable for metal sheet cutting scenarios requiring high stacking accuracy and material handling efficiency. The gear 260, tooth groove, and transmission components can be made of wear-resistant steel or high-strength alloy materials. A sliding guide mechanism or low-friction slide rail is installed between the extension plate 240 and the unloading plate 210, which helps extend service life and ensure stable operation. The meshing surface of the gear 260 can be hardened to improve load capacity.

[0074] In other alternative implementations, the drive structure can also be configured with a position feedback sensor to detect the current position of the extension plate 240 and correct its movement path. It can also be combined with an angle sensor for the unloading plate 210 or a stacking height detection device to achieve fully automatic closed-loop control. For applications with limited space or slow stacking pace, a simplified gear 260 structure or a manual locking mechanism can be used to replace the drive components, further simplifying cost and maintenance.

[0075] In this embodiment, a drive structure that engages with a rotating shaft 250, a gear 260, and a linear toothed groove 241 is adopted. Combined with an extension plate 240 located in the linear groove 212 of the unloading plate 210, the position of the extension plate 240 is controlled and adjusted. Therefore, the problem that the extension plate 240 cannot match the unloading endpoint position in a timely manner according to the angle change of the unloading plate 210 in the prior art is effectively solved. This results in improved docking accuracy, enhanced stacking consistency, and improved unloading stability during the copper plate sliding process.

[0076] To further optimize the sliding trajectory of the cut copper plate on the unloading plate 210, reduce the risk of collision, jamming, or warping between the leading edge of the copper plate and the end of the unloading plate 210, and improve the smoothness and stability of the copper plate during the sliding process, in some embodiments, see Figure 5 The side of the unloading plate 210 facing away from the cutting body 10 is constructed with an arc-shaped chamfer 213.

[0077] The arc-shaped chamfer 213 is a smooth curved surface structure at the transition between the front edge of the unloading plate 210 and its lower surface. Its cross-section is a continuously curving arc segment. This chamfer structure can form a fixed arc or be designed as an asymmetrical curvature form according to the unloading angle. This chamfer is set at the end area of ​​the copper plate's sliding direction, that is, the transition section where the unloading plate 210 guides the copper plate to slide above the support plate, thus forming a smooth transition area at the end of the sliding path.

[0078] The curved chamfer 213 structure can be geometrically completed through machining, bending, or welding. Its material is consistent with the unloading plate 210 body and can be wear-resistant steel, stainless steel, or other composite materials suitable for metal sliding. To further reduce frictional resistance, the surface of the curved chamfer 213 can be polished or coated with a low-friction coating, such as fluorocarbon spraying or polytetrafluoroethylene coating, to ensure a smooth transition of the leading edge to the support plate during copper plate sliding.

[0079] During the unloading process, the copper plate is cut and slides down the unloading plate 210 to the top of the receiving plate. If the end of the unloading plate 210 has a right-angle edge, the copper plate is prone to getting stuck or shifting when it contacts the edge, especially when the copper plate is soft or moving at a high speed. By setting an arc-shaped chamfer 213 structure, the copper plate can form a natural sliding transition in the end area, avoiding impact, stacking deviation, or stacking disorder caused by abrupt edge changes.

[0080] This structure is particularly suitable for high-frequency cutting, automatic stacking, and high-speed copper plate sliding operations, and is compatible with copper plate materials with a wide range of thicknesses and large differences in stiffness. In industrial sites with limited space, this structure requires no additional mechanisms and does not affect the swinging or angle adjustment of the unloading plate 210, and can be directly integrated into the edge of the existing unloading plate 210.

[0081] In other alternative implementations, the curved chamfer 213 can also be designed as a multi-segment combination structure, such as with a flexible buffer layer, magnetic guide plate, or roller-type corner assembly, to further improve the copper plate contact experience. For specific plate materials, such as coated copper plates or soft copper strips, auxiliary guide rails or positioning limit plates can also be set in the curved chamfer 213 area to achieve material feeding direction control.

[0082] In this embodiment, by using the technical means of constructing the side of the unloading plate 210 away from the cutting body 10 as an arc-shaped chamfer 213, the problem of the copper plate not sliding smoothly, the leading edge lifting or the stacking being uneven caused by the abrupt change at the end of the unloading plate 210 in the prior art is effectively solved. Thus, the technical effects of improving the smoothness of the copper plate sliding process, enhancing the stacking accuracy and unloading stability are achieved.

[0083] To ensure that the extension plate 240 at the end of the unloading plate 210 maintains a straight guiding direction and avoids abnormal states such as offset, tilting, or jamming during its telescopic movement, the unloading plate 210 is provided with a guide structure for constraining the movement direction of the extension plate 240. In some embodiments, see... Figures 3 to 4 A guide groove is provided on one side of the inner wall of the receiving groove 211, and a guide member is provided on the extension plate 240. The guide member is slidably disposed in the guide groove so that the extension plate 240 can move along the extension direction of the guide groove. The extension direction of the guide groove is parallel to the direction from the side of the unloading plate 210 near the cutting body 10 to the side of the unloading plate 210 away from the cutting body 10.

[0084] Specifically:

[0085] A guide groove extending along its length is provided on one side of the inner wall of the receiving groove 211 constructed at the end of the unloading plate 210. This guide groove has a closed or open structure, and its cross-section can be rectangular, semi-circular, dovetail, or other structural shapes that facilitate guiding and sliding, used to define the movement trajectory of the extension plate 240. The guide groove extends in a direction from the end of the unloading plate 210 near the cutting body 10 to the end away from the cutting body 10, that is, consistent with the direction of copper plate sliding, to ensure that the linear movement of the extension plate 240 is coordinated with the unloading action.

[0086] The extension plate 240 is provided with a guide member, which is slidably fitted into the guide groove. The guide member can be a slider, guide post, roller, or flexible guide rail assembly, which cooperates with the guide groove to form a linear motion pair, realizing linear reciprocating motion along a fixed trajectory. A small gap is reserved between the guide member and the guide groove or a rolling component is provided to reduce frictional resistance and improve guiding accuracy.

[0087] During equipment operation, the extension plate 240 moves along its length under the action of the drive mechanism or gear 260 structure. Since the guide component always maintains a stable fit with the guide groove, it ensures that the movement direction of the extension plate 240 is always parallel to the axial direction of the unloading plate 210 structure throughout the entire stroke, preventing lateral offset or attitude deflection during movement, and further ensuring the linear stability of the unloading path and the consistency of the copper plate stacking position.

[0088] This structure is particularly suitable for cutting environments requiring high stacking accuracy and consistent copper plate guidance. Guide channels and guide components can be made of high-strength, low-friction materials such as anodized aluminum, engineering plastics, or stainless steel alloys, and can be optionally equipped with lubricated guide rails or self-lubricating bushings to extend structural life and reduce maintenance needs. The structure is easy to install and can be directly integrated with existing unloading plate 210 structures without requiring additional space.

[0089] In other alternative embodiments, guide grooves can also be arranged on both sides of the receiving groove 211 to form a bidirectional guide structure, or higher precision movement constraints can be achieved in the form of magnetic slide rails, ball screws, etc. The guide component can also be combined with a position sensor to build a position closed-loop control system for real-time feedback and correction of the movement state of the extension plate 240.

[0090] In this embodiment, by using a guide groove in the receiving groove 211 and a guide member on the extension plate 240 slidingly engaging with the guide groove, the problem of positional shift, attitude change, or even jamming of the extension plate 240 during movement in the prior art is effectively solved. This achieves the technical effects of linear stability of the movement path of the extension plate 240, precise and consistent material unloading and docking, and improved overall machine reliability.

[0091] To improve the structural stability and synchronization of the unloading plate 210 during rotation adjustment, this application further provides a linkage auxiliary mechanism 2110 in the unloading mechanism 20. This mechanism mainly consists of a fixed base 290, a fixed shaft 2100, and a linkage 2110, constructing a mechanical support and guidance system that provides additional constraint and auxiliary positioning for the unloading plate 210 during swinging. See also the following embodiments: Figure 1 and Figure 3 The unloading mechanism 20 includes a fixed base 290, a fixed shaft 2100, and a connecting rod 2110. The fixed base 290 is connected to the cutting body 10; the fixed shaft 2100 is connected to the unloading plate 210; one end of the connecting rod 2110 is rotatably connected to the fixed base 290, and the other end of the connecting rod 2110 is rotatably connected to the fixed shaft 2100.

[0092] Specifically:

[0093] The fixed base 290 is a support structure that is firmly connected to the cutting body 10. It is usually installed below or on the side of the unloading mechanism 20 as the fixed end of the connecting rod 2110 assembly. The fixed shaft 2100 is set on the unloading plate 210 and serves as the rotational connection point between the unloading plate 210 and the connecting rod 2110. Its position is set in the area of ​​the unloading plate 210 near the end away from the cutting body 10 so as to form a suitable lever arm during the swinging process.

[0094] The connecting rod 2110 is a rotatable connecting component. One end is rotatably connected to the fixed base 290 via a rotating shaft 250 or a pin, and the other end is also rotatably connected to the fixed shaft 2100 on the unloading plate 210, thereby forming a constraint path. This allows the unloading plate 210 to generate coordinated rotational motion through the connecting rod 2110 during the angle adjustment process with the telescopic mechanism 220, thus limiting unnecessary swaying or posture changes.

[0095] During equipment operation, when the unloading plate 210 swings up or down due to the movement of the telescopic mechanism 220, the fixed shaft 2100 changes position along with the unloading plate 210. Since one end of the connecting rod 2110 is fixed to the fixed seat 290, while the other end moves with the fixed shaft 2100, the entire connecting rod 2110 forms a corresponding swing trajectory. This mechanism can effectively control the movement path of the unloading plate 210, suppressing problems such as excessively rapid swinging, asymmetrical offset, or posture jitter within a certain range. In particular, it helps maintain the flatness of the unloading plate 210 during the copper plate sliding process, ensuring the continuity and stability of the copper plate's descent.

[0096] This structure is suitable for medium-to-long length unloading plates 210 or copper plate sliding systems with significant inertial variations, and is particularly effective in improving the controllability and repeatability of the unloading plate 210's movement. The fixed base 290, fixed shaft 2100, and connecting rod 2110 can be made of structural steel or high-strength alloy materials. Lubricated bushings or rolling joints can be provided at the connection points to improve rotational flexibility and wear resistance. The length and connection position of the connecting rod 2110 can be designed as a single-section or multi-section structure according to the dimensions and tilt range of the unloading plate 210.

[0097] In other alternative embodiments, the link 2110 structure can also be combined with a damper or elastic element to form a buffer system to absorb the impact load generated during rapid swinging; a position sensor can also be set to monitor the angle of the link 2110 in real time for use in the linkage control system to achieve closed-loop action adjustment.

[0098] In this embodiment, by employing an auxiliary linkage structure consisting of a fixed base 290, a fixed shaft 2100, and a connecting rod 2110, and by establishing a multi-point support and rotational guidance relationship between the unloading plate 210 and the cutting body 10, the problem of unstable posture, swaying and shaking, and copper plate slippage and offset that easily occur during the swing adjustment process of the unloading plate 210 in the prior art is effectively solved. Thus, the technical effects of precise synchronization of unloading action, stable guidance of slippage path, and overall system reliability are achieved.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
