Description

Technical Field

[0001] This application relates to the field of mold steel processing technology, and in particular to a gantry milling machine for mold steel processing. Background Technology

[0002] Die steel refers to a type of alloy tool steel made by adding alloying elements such as chromium (Cr), manganese (Mn), molybdenum (Mo), tungsten (W), vanadium (V), nickel (Ni), and silicon (Si) to carbon steel. It is used to manufacture various types of molds, and is specifically used to manufacture molds such as cold stamping dies, hot forging dies, and die casting dies.

[0003] A gantry milling machine, or simply gantry milling machine, is a type of milling machine with a gantry frame and a horizontal long bed. Its gantry frame consists of columns and a top beam, and the crossbeam can rise and fall along the columns. Multiple milling heads with independent motors can be mounted on the crossbeam and columns, enabling efficient and high-precision machining of large workpieces. It is the main equipment for machining mold steel.

[0004] A gantry milling machine for machining mold steel exists in the prior art. It includes a gantry frame and a base frame. A machining table and a sliding assembly are mounted on the base frame. The sliding assembly drives the machining table to slide relative to the length of the base frame. A moving mechanism and a milling cutter mechanism are mounted on the gantry frame. The moving mechanism moves the milling cutter mechanism along the width and height directions of the machining table. The milling cutter mechanism is used to machine the mold steel on the machining table. In use, the mold steel to be machined is placed on the machining table and fixed in place. Then, the milling cutter mechanism machines the mold steel.

[0005] Regarding the aforementioned technologies, a large amount of waste is generated during the processing of mold steel. This means that after each processing of mold steel, workers must manually clean the waste from the processing table before proceeding to the next processing. This increases the workload of workers and reduces the processing efficiency of mold steel. Summary of the Invention

[0006] To facilitate the cleaning of waste chips on the machining table, this application provides a gantry milling machine for machining mold steel.

[0007] This application provides a gantry milling machine for machining mold steel, which adopts the following technical solution: A gantry milling machine for machining mold steel includes a base frame and a gantry frame. A machining table is mounted on the base frame, and a milling cutter mechanism for machining the mold steel is mounted on the gantry frame. A plurality of chip grooves are formed on the top wall of the machining table, and the chip grooves extend along the width direction of the machining table, with both ends extending to the outside. A cleaning mechanism is also provided on the machining table, and the cleaning mechanism includes a cleaning frame and a drive assembly. The bottom of the cleaning frame is embedded in each chip groove, and the drive assembly is used to drive the cleaning frame to move along the width direction of the machining table.

[0008] By adopting the above technical solution, the waste chip trough and cleaning mechanism are designed so that the waste chips generated during processing can fall into the waste chip trough, thereby reducing the probability of waste chips accumulating on the surface of the processing table. At the same time, the existence of the cleaning mechanism also enables the drive component to move the cleaning frame along the width direction of the processing table, thereby pushing the waste chips out of the waste chip trough and cleaning the waste chips in the waste chip trough. This reduces the probability of waste chips continuously accumulating in the waste chip trough, thus effectively facilitating the cleaning of waste chips on the processing table and ensuring the subsequent processing efficiency of mold steel.

[0009] Preferably, the processing table is also provided with a clamping mechanism, which includes two clamping frames and a moving component. The two clamping frames are located on both sides of the processing table in the width direction and are slidably connected to the processing table. The sliding direction of both clamping frames is the width direction of the processing table. The moving component is used to drive both clamping frames to slide.

[0010] By adopting the above technical solution and setting the clamping mechanism, when it is necessary to process the mold steel, the relevant personnel can move the clamping frame to slide by moving the component, so that the clamping frame can clamp, position and fix the mold steel, thus ensuring the processing effect of the mold steel.

[0011] Preferably, the number of cleaning racks and drive components is set to two, and they are correspondingly arranged. Each cleaning rack is slidably connected to a corresponding clamping rack, and the sliding direction is the height direction of the corresponding clamping rack. Each drive component is used to drive the corresponding cleaning rack to slide.

[0012] By adopting the above technical solution, the cleaning frame and the clamping frame are designed so that the clamping frame can slide together with the cleaning frame. During the sliding process, the cleaning frame can automatically clean the waste in the waste chute, which effectively facilitates the operation of the operator. The drive component can drive the cleaning frame to rise and fall, so that when the cleaning frame moves closer to the center of the processing table with the clamping frame, it can separate from the waste chute, thereby reducing the probability of pushing the waste to the center of the processing table and reducing the probability of waste accumulation.

[0013] Preferably, the drive assembly includes a drive slide rail and a drive rod. The drive slide rail has a parallel groove, a descending groove, and a lifting groove. The descending groove is located on the side of the drive slide rail closer to the center of the processing table, and the lifting groove is located on the side of the drive slide rail away from the center of the processing table. There are two parallel grooves, both extending along the width direction of the processing table and distributed along the height direction of the processing table. Both ends of each parallel groove are connected to the corresponding descending groove and the corresponding lifting groove, respectively. One end of the drive rod is connected to the corresponding cleaning frame, and the other end extends into the corresponding parallel groove and abuts against the inner wall of the corresponding parallel groove.

[0014] By adopting the above technical solution and configuring the drive assembly, when the cleaning frame slides together with the gripper frame, the drive rod on the cleaning frame can be displaced in the corresponding parallel groove, descending groove, or lifting groove. This allows the drive rod to gradually move from the lower parallel groove to the lifting groove after the cleaning frame slides out of the waste chip trough. The inner wall of the lifting groove abuts against the drive rod, causing it to slide upwards. This ensures that when the gripper frame slides back, the drive rod is restricted by the upper parallel groove and remains in a lifted state, reducing the likelihood of pushing waste chips to the center of the processing table. Furthermore, when the gripper frame moves back to the center of the processing table, the drive rod can re-enter the lower parallel groove via the descending groove for further cleaning of the waste chips, effectively ensuring the cleaning effect.

[0015] Preferably, each of the cleaning racks is provided with a self-locking mechanism, which includes a transmission component and a self-locking frame. One end of the self-locking frame is rotatably connected to the corresponding clamping frame. The cleaning rack is used to drive the self-locking frame to rotate through the transmission component. The other end of the self-locking frame is used to abut against the corresponding clamping frame after rotation to prevent the corresponding cleaning rack from continuing to slide.

[0016] By adopting the above technical solution and configuring the self-locking mechanism, when the drive rod slides upward with the cleaning frame and reaches the top of the lifting groove, and then moves downward, the cleaning frame can drive the self-locking frame to rotate downward through the transmission component. This causes the end of the self-locking frame to abut against the clamping frame, preventing the self-locking frame from rotating further and thus preventing the cleaning frame from descending further. This allows the drive rod on the cleaning frame to smoothly enter the parallel groove above, achieving self-locking between the cleaning frame and the clamping frame. This effectively ensures the smooth operation of the cleaning frame and reduces the probability of the cleaning frame pushing waste to the center of the processing table.

[0017] Preferably, the self-locking mechanism further includes a sliding frame and a transmission frame. The sliding frame is slidably connected to the corresponding clamping frame. The cleaning frame is used to drive the corresponding sliding frame to slide through the transmission component. One end of the transmission frame is rotatably connected to the corresponding sliding frame, and the other end is rotatably connected to the corresponding self-locking frame.

[0018] By adopting the above technical solution, the sliding frame and transmission frame are configured such that when the drive rod gradually enters the lifting groove, the cleaning frame can drive the sliding frame to slide through the transmission component. This causes the sliding frame to drive the end of the self-locking frame to gradually rotate downwards through the transmission frame, making the self-locking frame gradually parallel to the transmission frame. After the rotational connection between the self-locking frame and the transmission frame passes the parallel state, it can rotate downwards and abut against the top wall of the clamping frame, thus achieving self-locking of the sliding frame. In this way, the self-locking of the sliding frame achieves self-locking of the cleaning frame, effectively ensuring the self-locking effect and allowing the cleaning frame to be lifted smoothly.

[0019] Preferably, the connection between the parallel groove and the lifting groove is located below the top of the lifting groove, and when the drive rod moves to the top of the lifting groove, the rotatable connection points at both ends of the transmission frame and the rotatable connection points at both ends of the self-locking frame are on the same straight line.

[0020] By adopting the above technical solution, the connection between the parallel groove and the lifting groove is designed so that when the drive rod moves to the top of the lifting groove, the rotating connection points at both ends of the transmission frame and the rotating connection points at both ends of the self-locking frame can be on the same straight line. This allows the rotating connection points between the transmission frame and the self-locking frame to cross the straight line when the drive rod moves downward along the extension direction of the lifting groove, and then abut against the top wall of the clamping frame, thereby achieving self-locking of the sliding frame.

[0021] Preferably, the transmission component includes a transmission rod, one end of which is rotatably connected to the corresponding cleaning frame, and the other end of which is rotatably connected to the corresponding sliding frame.

[0022] By adopting the above technical solution and setting the transmission rod, the cleaning frame can smoothly drive the sliding frame to slide, thereby enabling the sliding frame to slide continuously.

[0023] Preferably, each of the cleaning frames is provided with an abutment frame on the side closest to another cleaning frame, and each of the self-locking frames is provided with an abutment roller on the end away from itself and rotatably connected to the clamping frame. The abutment frame is located on the sliding path when the bottom of the corresponding abutment roller slides together with the corresponding clamping frame.

[0024] By adopting the above technical solution, the setting of the abutting frame and the abutting roller allows the abutting frame to abut against the bottom of the abutting roller when the cleaning frame slides together with the clamping frame and approaches the center of the processing table. This causes the self-locking frame to rotate upward, thus passing through the straight line state and automatically unlocking the sliding frame and the cleaning frame. This allows the drive rod to smoothly enter the lowering groove, and the bottom of the cleaning frame to smoothly enter the waste chip groove, ensuring the cleaning effect of waste chips.

[0025] Preferably, the top wall of the gripper is located on the rotation path of the end of the self-locking frame. The gripper is also provided with a counterweight and a pull rod. The counterweight is slidably connected to the corresponding gripper, and the sliding direction is the height direction of the corresponding gripper. One end of the pull rod is rotatably connected to the counterweight, and the other end is rotatably connected to the corresponding self-locking frame.

[0026] By adopting the above technical solution, the counterweight and the pull rod are configured so that when the drive rod moves downward from the top of the lifting groove, the rotational connection points at both ends of the transmission frame and the rotational connection points at both ends of the self-locking frame are on the same straight line. Under the action of its own gravity, the counterweight can pull the self-locking frame downward through the pull rod to rotate, thereby ensuring that the self-locking frame can smoothly pass through the straight line state and ensuring the smooth self-locking of the self-locking frame.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. The design of the waste chip trough and cleaning mechanism allows the waste chips generated during processing to fall into the waste chip trough, thereby reducing the probability of waste chips accumulating on the surface of the processing table. At the same time, the existence of the cleaning mechanism also enables the drive component to move the cleaning frame along the width direction of the processing table, thereby pushing the waste chips out of the waste chip trough and cleaning the waste chips in the waste chip trough. This reduces the probability of waste chips continuously accumulating in the waste chip trough, thus effectively facilitating the cleaning of waste chips on the processing table and ensuring the subsequent processing efficiency of mold steel. 2. The design of the cleaning frame and the clamping frame allows the clamping frame to slide together with the cleaning frame. During the sliding process, the cleaning frame can automatically clean the waste in the waste chute, which effectively facilitates the operation of the operator. The drive component can drive the cleaning frame to rise and fall, so that when the cleaning frame and the clamping frame approach the center of the processing table, they can separate from the waste chute, thereby reducing the probability of pushing the waste to the center of the processing table and reducing the probability of waste accumulation. 3. The drive assembly is designed so that when the cleaning frame slides together with the gripper, the drive rod on the cleaning frame can move within the corresponding parallel groove, descending groove, or lifting groove. This allows the drive rod to gradually move from the lower parallel groove to the lifting groove after the cleaning frame slides out of the waste chip tray. The inner wall of the lifting groove abuts against the drive rod, causing it to slide upwards. When the gripper slides back, the drive rod is restricted by the upper parallel groove, remaining in a lifted state. This reduces the likelihood of pushing waste chips to the center of the processing table. When the gripper moves back to the center of the processing table, the drive rod can re-enter the lower parallel groove via the descending groove for further cleaning of the waste chips, effectively ensuring the cleaning effect.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a gantry milling machine for machining mold steel. (Refer to...) Figure 1 , Figure 2 and Figure 3A gantry milling machine for machining mold steel includes a base frame 1 and a gantry frame 2. A machining table 3 is mounted on the base frame 1, and a milling cutter mechanism 4 for machining the mold steel is mounted on the gantry frame 2. Several chip grooves 31 are formed on the top wall of the machining table 3, extending along the width direction of the machining table 3 and extending to the outside at both ends. A cleaning mechanism 5 is also provided on the machining table 3, comprising a cleaning frame 51 and a drive assembly 52. ​​The bottom of the cleaning frame 51 is embedded in each chip groove 31, and the drive assembly 52 drives the cleaning frame 51 to move along the width direction of the machining table 3.

[0035] Reference Figure 1 and Figure 2 The gantry frame 2 is placed on the ground, and its length direction is the same as the width direction of the base frame 1. The gantry frame 2 is also provided with a moving mechanism 6. In this embodiment, the moving mechanism 6 is configured as a linear module and a lifting module. The linear module is fixedly installed on the top of the gantry frame 2, and its length direction is the same as the length direction of the gantry frame 2, so that the sliding direction of its sliding seat is the length direction of the gantry frame 2.

[0036] The lifting module is fixedly mounted on the sliding seat of the linear module, and the sliding direction of the sliding seat on the lifting module is vertical. In this embodiment, the milling cutter mechanism 4 includes a setting box, a milling cutter, a reduction motor, and a transmission gear set. The setting box is fixedly mounted on the sliding seat of the lifting module, and the milling cutter is located at the bottom of the setting box and is rotatably connected to the setting box via a bearing. The reduction motor is fixedly mounted on the top of the setting box and is driven by the milling cutter via the transmission gear set.

[0037] Reference Figure 1 The base frame 1 is placed on the ground, and the processing table 3 is slidably connected to the base frame 1 via a slide rail, with the sliding direction being the length direction of the base frame 1. The base frame 1 is also equipped with a sliding component 7. In this embodiment, the sliding component 7 is configured as a linear module, which is fixedly installed on the base frame 1. The sliding seat on the linear module is fixedly connected to the bottom of the processing table 3 to drive the processing table 3 to slide.

[0038] Reference Figure 1 and Figure 3 The processing table 3 is also equipped with a clamping mechanism 8, which includes two clamping frames 81 and a moving component 82. The two clamping frames 81 are located on both sides of the processing table 3 in the width direction, and their bottoms extend to the corresponding sides in the length direction of the processing table 3. Each clamping frame 81 is slidably connected to the processing table 3 through a sliding groove, and the sliding direction is the width direction of the processing table 3.

[0039] In this embodiment of the application, the moving component 82 is configured as two linear modules, which are correspondingly arranged with two grippers 81. Each linear module is fixedly installed on the processing table 3, and the sliding seat on the linear module is fixedly connected to the bottom of the corresponding gripper 81 to drive the corresponding gripper 81 to slide.

[0040] Reference Figure 1 and Figure 3 There are two cleaning frames 51, which are arranged one-to-one with the clamping frames 81 and are located on the side of the corresponding clamping frame 81 away from the other clamping frame 81. Each cleaning frame 51 has several pushing parts 511 extending downward from its bottom. Each pushing part 511 is integrally formed with the corresponding cleaning frame 51 and is embedded in the corresponding waste chute 31. The bottom wall and side wall of each pushing part 51 abut against the inner wall of the waste chute 31 so as to push out the waste chute 31 when moving.

[0041] Reference Figure 1 and Figure 3 Each cleaning frame 51 is slidably connected to the corresponding clamping frame 81 via a sliding groove, and the sliding direction is set to the height direction of the corresponding clamping frame 81. In this embodiment, the number of drive components 52 is set to two groups, corresponding to the two cleaning frames 51. The number of drive components 52 in each group is set to two, and the drive components 52 in each group are located at both ends of the length direction of the processing table 3.

[0042] Reference Figure 1 , Figure 3 and Figure 4 Each drive assembly 52 includes a drive slide rail 521 and a drive rod 522. Each drive slide rail 521 is fixedly installed on the corresponding side wall of the processing table 3, and each drive slide rail 521 is provided with a parallel groove 5211, a descending groove 5212, and a lifting groove 5213. The descending groove 5212 is located on the side of the drive slide rail 521 closer to the center of the processing table 3, and the lifting groove 5213 is located on the side of the drive slide rail 521 away from the center of the processing table 3.

[0043] Reference Figure 1 and Figure 4 The descending groove 5212 extends along the height of the processing table 3. The lifting groove 5213 is an arc-shaped groove with one end extending upwards. Two parallel grooves 5211 are provided, distributed along the height of the processing table 3 and extending along its width. One end of the lower parallel groove 5211 is connected to the bottom of the descending groove 5212, and the other end is connected to the bottom of the lifting groove 5213. One end of the upper parallel groove 5211 is connected to the top of the descending groove 5212, and the other end is connected to the top of the lifting groove 5213. The top height of the lifting groove 5213 is greater than the end height of the upper parallel groove 5211.

[0044] Reference Figure 4 Each drive slide rail 521 is also provided with an adaptation groove 5214. One end of the adaptation groove 5214 is connected to the end of the upper parallel groove 5211 near the lowering groove 5212, and the other end extends upward and, after reaching the same height as the top of the lifting groove 5213, extends downward until it is connected to the top of the lowering groove 5212.

[0045] Reference Figure 3 and Figure 4 Both drive rods 522 in the same group are set as cylindrical rods, and the two drive rods 522 are located at both ends of the length direction of the corresponding cleaning frame 51. One end of each rod is fixedly connected to the corresponding cleaning frame 51, and the other end extends into the corresponding parallel groove 5211. The arc-shaped sidewalls of each rod abut against the inner wall of the corresponding parallel groove 5211.

[0046] Reference Figure 3 and Figure 4 Each cleaning frame 51 is equipped with a self-locking mechanism 9 at both ends along its length. Each self-locking mechanism 9 includes a transmission component 91, a sliding frame 92, a transmission frame 93, and a self-locking frame 94. Each transmission component 91 includes a transmission rod 911. One end of each transmission rod 911 is sleeved on the corresponding drive rod 522 and is rotatably connected to the corresponding drive rod 522. The other end is rotatably connected to the corresponding sliding frame 92 via a pin.

[0047] Reference Figure 3 and Figure 4 Each sliding frame 92 is slidably connected to its corresponding gripping frame 81 via a sliding groove, and the sliding direction is the same as that of the gripping frame 81. One end of each transmission frame 93 is rotatably connected to its corresponding sliding frame 92 via a pin, and the other end is rotatably connected to one end of its corresponding self-locking frame 94 via a pin. The other end of each self-locking frame 94 is rotatably connected to its corresponding gripping frame 81 via a pin.

[0048] Reference Figure 3 and Figure 4 In this embodiment, the lengths of the self-locking frame 94, the transmission frame 93, and the transmission rod 911 are specifically set so that when the drive rod 522 moves to the top of the lifting groove 5213, the cleaning frame 51 is raised to the top of its own sliding path. At this time, the transmission frame 93 and the self-locking frame 94 can be in a parallel state (that is, the rotating connection points at both ends of the transmission frame 93 and the rotating connection points at both ends of the self-locking frame 94 are on the same straight line). In this embodiment, each gripping frame 81 also has an opening at its top for the rotating connection points of the self-locking frame 94 and the transmission frame 93 to abut. When the corresponding self-locking frame 94 rotates downward, it abuts against the end of the corresponding self-locking frame 94 to self-lock the self-locking frame 94, thereby preventing the corresponding sliding frame 92 from continuing to slide.

[0049] Reference Figure 3 and Figure 4 Each gripper 81 has a counterweight 95 and a pull rod 96 at both ends along its length. One end of each pull rod 96 is rotatably connected to the end of the corresponding self-locking frame 94 near the transmission frame 93 via a pin, and the other end of each pull rod 96 is rotatably connected to the corresponding counterweight 95. Each counterweight 95 is slidably connected to the corresponding gripper 81 via a slide rail, and the sliding direction is set to the height direction of the gripper 81.

[0050] Reference Figure 1 , Figure 3 and Figure 4 In the initial state, when the drive rod 522 is located in the lower lifting groove 5213, the push part 511 on the cleaning frame 51 is located in the waste chip groove 31. At this time, the cleaning frame 51 is located at the bottom of its own sliding path, and the sliding frame 92 is located on the side of its own sliding path away from the cleaning frame 51. At this time, the end of the self-locking frame 94 that is rotatably connected to the transmission frame 93 is tilted upward.

[0051] After the pusher 511 moves out of the waste chute 31, the drive rod 522 gradually moves into the lifting chute 5213. At this time, the inner wall of the lifting chute 5213 pushes the cleaning frame 51 upward by abutting against the drive rod 522. During this process, the drive rod 522 on the lifting frame drives the sliding frame 92 to gradually approach the cleaning frame 51 via the transmission rod 911, thereby causing the sliding frame 92 to drive the self-locking frame 94 to rotate downward via the transmission frame 93. During this process, the self-locking frame 94 drives the counterweight 95 to slide downward by pulling the frame.

[0052] When the drive rod 522 moves to the top of the lifting groove 5213, the cleaning frame 51 moves to the top of its sliding path. At this point, the transmission frame 93 and the self-locking frame 94 are parallel (i.e., the rotatable connections at both ends of the transmission frame 93 and the rotatable connections at both ends of the self-locking frame 94 are on the same straight line). Then, the clamping frame 81 gradually slides closer to the processing table 3, causing the drive rod 522 to displace downwards along the extension direction of the lifting groove 5213.

[0053] During this process, the counterweight 95, under its own power, drives the self-locking frame 94 past the parallel state with the transmission frame 93 via the pulling rod 96, thus causing the self-locking frame 94 to continue rotating downwards. When the rotating connection between the self-locking frame 94 and the support of the transmission frame 93 abuts against the top wall of the opening at the top of the clamping frame 81, the self-locking frame 94 can hardly continue to rotate, thus maintaining the current state of the self-locking frame 94. At this time, the drive rod 522 moves to the connection between the lifting groove 5213 and the upper parallel groove 5211. After that, the drive rod 522 moves into the upper parallel groove 5211, so that the cleaning frame 51 maintains the lifted state. At this time, the pusher part 511 is no longer embedded in the waste trough.

[0054] Reference Figure 3 and Figure 4 The self-locking frame 94 is rotatably connected to the transmission frame 93, and an abutment roller 97 is also provided on one end. The abutment roller 97 is rotatably connected to the self-locking frame 94 by a pin and is located outside the side wall of the clamping frame 81. Each cleaning frame 51 is provided with an abutment frame 98 on the side near the other cleaning frame 51, and each abutment frame 98 is fixedly installed on the corresponding drive slide rail 521.

[0055] Reference Figure 3 and Figure 4 Each abutment frame 98 has an arc-shaped guide surface on the side of its top away from the center of the processing table 3. The outer wall of each arc-shaped guide surface is located on the displacement path of the corresponding abutment roller 97 as it slides together with the clamping frame 81. This allows the abutment frame 98 to push the abutment roller 97 upward through the abutment action after the abutment roller 97 comes into contact with the abutment frame 98.

[0056] Reference Figure 1 , Figure 3 and Figure 4 When the abutting roller 97 abuts against the abutting frame 98, the drive rod 522 moves into the adaptation groove 5214. The clamping frame 81 then continues to move, causing the self-locking frame 94 to rotate upwards, bringing it back to a parallel position with the transmission frame 93. At this point, the drive rod 522 moves to the top of the adaptation groove 5214. Then, the end of the self-locking frame 94 rotatably connected to the transmission frame 93 rotates to an upward tilted position, releasing the self-locking mechanism of the self-locking frame 94. Next, the drive rod 522 moves into the descending groove 5212, allowing the cleaning frame 51 to slide downwards under its own weight. This causes the drive rod 522 to descend to a position flush with the lower parallel groove 5211, allowing the drive rod 522 to move into the lower parallel groove 5211 when the clamping frame 81 moves away from the center of the processing table 3, thereby pushing the waste in the waste chip trough 31.

[0057] The implementation principle of a gantry milling machine for machining mold steel according to an embodiment of this application is as follows: After the pusher 511 moves out of the waste chip tray 31, the drive rod 522 gradually moves into the lifting tray 5213. At this time, the inner wall of the lifting tray 5213 pushes the cleaning frame 51 upward by abutting against the drive rod 522. During this process, the drive rod 522 on the lifting frame drives the sliding frame 92 to gradually approach the cleaning frame 51 through the transmission rod 911, thereby causing the sliding frame 92 to drive the self-locking frame 94 to rotate downward through the transmission frame 93. During this process, the self-locking frame 94 drives the counterweight 95 to slide downward through the pull frame.

[0058] When the drive rod 522 moves to the top of the lifting groove 5213, the cleaning frame 51 moves to the top of its sliding path. At this point, the transmission frame 93 and the self-locking frame 94 are parallel (i.e., the rotatable connections at both ends of the transmission frame 93 and the rotatable connections at both ends of the self-locking frame 94 are on the same straight line). Then, the clamping frame 81 gradually slides closer to the processing table 3, causing the drive rod 522 to displace downwards along the extension direction of the lifting groove 5213.

[0059] During this process, the counterweight 95, under its own power, drives the self-locking frame 94 past the parallel state with the transmission frame 93 via the pulling rod 96, thus causing the self-locking frame 94 to continue rotating downwards. When the rotating connection between the self-locking frame 94 and the support of the transmission frame 93 abuts against the top wall of the opening at the top of the clamping frame 81, the self-locking frame 94 can hardly continue to rotate, thus maintaining the current state of the self-locking frame 94. At this time, the drive rod 522 moves to the connection between the lifting groove 5213 and the upper parallel groove 5211. After that, the drive rod 522 moves into the upper parallel groove 5211, so that the cleaning frame 51 maintains the lifted state. At this time, the pusher part 511 is no longer embedded in the waste trough.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
