Technical Field
[0001] This invention relates to the field of cable tray cutting equipment technology, specifically to a cable tray cutting and processing machine tool. Background Technology
[0002] Cable trays are generally used as the carrier for laying cables in buildings. Cable trays are also known as metal cable troughs. Cable trays are installed at intervals on the top of each floor of the building by several supports. Moreover, during the laying process, the arrangement needs to be based on the structure of the building. Generally, on the construction site, semi-finished products of a certain length processed by the manufacturer are used for secondary processing. To adapt to the pace of automated cable tray production, a cable tray cutting machine is mounted on a slide rail, and the sliding speed of the machine is controlled by a CNC push rod. When cutting is required, the cutting position is kept relatively stationary with respect to the cable tray. However, in practical applications, such cutting equipment needs to consider the cable tray's heat dissipation holes, mounting holes, branch outlet holes, etc. When the holes slide along the inner wall of the slot, the protruding metal plate of the holes may limit the sliding efficiency of the cable tray, resulting in differences in cutting length. To address these issues, the following solutions are proposed. Summary of the Invention
[0003] To solve the above-mentioned technical problems, the present invention provides a bridge frame cutting machine tool, including a support frame, a sliding frame slidably connected to the top of the support frame, an electric push rod one fixedly connected to the side wall of the support frame, a fixing block fixedly connected to the top of the sliding frame, a bracket fixedly connected to the top of the fixing block, an electric push rod two fixedly connected to the top of the bracket, and a cutting blade fixedly connected to the output end of the electric push rod two, and further comprising: The contact mechanism is fixedly connected to the top of the fixed block and cooperates with the electric push rod to drive the sliding frame to slide along the outer track of the support frame. The expansion mechanism is fixedly connected to the inner wall of the contact mechanism. When the electric actuator retracts, the expansion mechanism adapts and reduces the contact area between the expansion mechanism and the cable tray. The auxiliary mechanism is fixedly connected to the outer wall of the contact mechanism. The electric actuator drives the auxiliary mechanism to deform through the contact mechanism. Before use, it is necessary to ensure that the cable tray passes through the contact mechanism and that the bend at the top of the cable tray is hooked to the inside of the contact mechanism.
[0004] Preferably, the contact mechanism includes: The tensioning component is slidably connected to the outer wall of the sliding frame via a linkage; The linkage includes a slide groove formed on the outer wall of the sliding frame, and a sliding block is slidably connected to the inner wall of the slide groove; The positioning component is fixedly connected to the top of the fixed block via a movable part; The moving part includes a moving plate fixedly connected to the top of the fixed block, the inner wall of the moving plate has a cavity, and the side wall of the cavity has a flow groove. During use, it is necessary to ensure that the bent position at the top of the cable tray and the recessed position at the top of the flow channel are in a sliding state, and that the inner wall of the cable tray remains tightly attached to the inner wall of the flow channel when the expansion mechanism expands.
[0005] Preferably, the expansion mechanism includes: A shielding assembly is fixedly connected to the inner wall of the cavity by means of a limiting member; The limiting components include an L-shaped baffle that is slidably connected to the inner wall of the cavity; The pushing component is fixedly connected to the inner wall of the cavity via a pressure-applying component; The pressure-applying component includes a rotating rod 1 rotatably connected to the inner wall of the cavity, a rotating rod 2 rotatably connected to the other end of the rotating rod 1, and a rotating rod 2 rotatably connected to the bottom of the L-shaped baffle at the end away from the rotating rod 1. Under normal conditions, rotating rod one and rotating rod two are in a folded state, and there is no overlap between the L-shaped baffle and the flow channel. However, when the auxiliary mechanism drives rotating rod one to rotate, rotating rod one and rotating rod two will rotate and push the L-shaped baffle to move outward. At this time, the L-shaped baffle will overlap with the flow channel.
[0006] Preferably, the auxiliary mechanism includes: The linkage component is fixedly connected to the top of the sliding block one by a tensioning component; The tensioning component includes a linkage rod fixedly connected to the top of the sliding block, a U-shaped frame fixedly connected to the side wall of the linkage rod, and a folding rod rotatably connected to the inner wall of the U-shaped frame; The cleaning component is slidably connected to the top of the sliding block one via a positioning element; The positioning component includes an L-shaped tie rod fixedly connected to one side wall of the sliding block, a movable block slidably connected to the top of the sliding frame, a rotating rod fixedly connected to the side wall of the movable block, and a rotating scraper rotatably connected to the outer wall of the rotating rod. When the sliding block 1 slides along the inner wall of the groove, the sliding block 1 will drive the rotating scraper to rotate around the rotating rod through the L-shaped tie rod.
[0007] Preferably, the pulling assembly includes a mounting plate fixedly connected to the bottom of the sliding block, and the output end of the electric push rod is fixedly connected to the outer wall of the mounting plate; When the electric actuator is running, it first drives the mounting plate and the sliding block to slide a short distance along the inner wall of the groove. The force generated by this distance will be transmitted to the expansion mechanism and the auxiliary mechanism, forcing the expansion mechanism and the auxiliary mechanism to deform.
[0008] Preferably, the positioning component includes a cutting groove formed on the top of the movable plate; In this process, when the electric push rod one drives the sliding frame to move along the outer wall of the support frame, and when the moving speed of the sliding frame is equal to the sliding speed of the cable tray, the electric push rod two pushes the cutter into the inner wall of the cutting groove and performs the cutting process on the cable tray.
[0009] Preferably, the shielding assembly includes a telescopic rod fixedly connected to the inner wall of the cavity, and the other end of the telescopic rod is fixedly connected to the side wall of the L-shaped baffle. When the L-shaped baffle is pressed and moves outward, the telescopic rod will restrict the direction of the L-shaped baffle's outward movement.
[0010] Preferably, the pushing component includes a blocking block fixedly connected to one side wall of the rotating rod; When rotating rod one and rotating rod two open outwards, when the angle between them reaches 181 degrees, the obstruction block will restrict their rotation, and at this time the outer wall of the L-shaped baffle will contact the outer wall of the cable tray.
[0011] Preferably, the linkage component includes a second sliding block rotatably connected to both ends of the folding rod, a sliding rod rotatably connected to the inner wall of the second sliding block, and the outer wall of the sliding rod rotatably connected to the outer wall of the first rotating rod. When the mounting plate is pulled outward, the linkage rod will cause the folding rod to fold. The folding rod will cause the two sliding blocks to slide. The sliding blocks will force the angle between the rotating rod and the rotating rod to widen through the sliding rod, eventually reaching 181 degrees.
[0012] Preferably, the cleaning assembly includes a fixed bracket fixedly connected to the top of the rotating scraper, and the outer wall of the L-shaped pull rod is rotatably connected to the inner wall of the fixed bracket; When the sliding block 1 is pushed inward, the sliding block 1 forces the sliding block 2 to tilt upward around the rotating rod via the L-shaped tie rod. At this time, the rotating scraper does not contact the metal debris at the bottom. When the L-shaped tie rod moves outward, the L-shaped tie rod first pulls the fixed bracket and the rotating scraper, forcing the end of the rotating scraper to contact the top of the sliding frame.
[0013] The present invention has the following beneficial effects: (1) This invention utilizes the regular extension and retraction characteristics of the electric actuator. Subsequently, the electric actuator generates an extension force, forcing the sliding frame to slide to the other end. At this time, the pressure generated by the electric actuator will force the mounting plate to reset, and at the same time force the linkage rod to drive the sliding blocks at both ends to reset. The sliding rod will then drive the rotating rod and the rotating rod to return to the bent state. Figure 8 The state changes to Figure 5In this state, the rotating rod two will drive the L-shaped baffle to retract. Through the application of the above components, when the cable tray slides along the inner wall of the flow channel, the L-shaped baffle will move away from the outer wall of the cable tray, preventing the metal plate on the outer wall of the cable tray from moving outward and affecting the cutting efficiency of the equipment.
[0014] (2) This invention utilizes the characteristics of the rotating rod one and rotating rod two to push the L-shaped baffle, and provides an obstruction block inside the equipment. Specifically, when the L-shaped baffle moves outward to its maximum angle of 181 degrees, as... Figure 8 As shown, when the L-shaped baffle is cut by the cutter at the top, the pressure is transmitted to the rotating rod 2. During this process, due to the presence of the telescopic rod 1, the L-shaped baffle can only slide along the preset path. However, if the L-shaped baffle slides, the rotating rod 1 and the rotating rod 2 need to be in a folded state. Since the angle between the rotating rod 1 and the rotating rod 2 is 181 degrees, when the top of the L-shaped baffle is pressed, the rotating rod 1 and the rotating rod 2 will rotate towards the obstruction block. However, the rotating rod 1 and the rotating rod 2 cannot rotate due to the obstruction block. Therefore, after the top of the L-shaped baffle is pressed, the pressure will be trapped inside the moving plate. Through the application of the above components, the pressure of the cutter is prevented from being transmitted to the mounting plate through the rotating rod 1 and the linkage components, which would affect the moving efficiency of the sliding frame and cause differences in the cutting length.
[0015] (3) This invention utilizes the regular expansion characteristic of the L-shaped baffle. After the equipment completes the cutting, the L-shaped baffle will move away from the outer wall of the cable tray. After the cutter completes the cutting of the outer wall of the cable tray, metal debris will remain. As the distance between the L-shaped baffle and the flow channel increases, the debris remaining inside will become loose due to the reduced contact area with the surrounding area. Finally, the debris will fall to the top of the sliding frame under the push of the subsequent cable tray. Through the application of the above components, it is effective to prevent metal debris from remaining inside the moving plate. The debris increases the friction between the cable tray and the equipment, affecting the efficiency of the cable tray passing through the flow channel.
[0016] (4) The present invention utilizes the feature of the sliding block 1 sliding along the inner wall of the groove. When the sliding block 1 is pushed inward, the sliding block 1 forces the sliding block 2 to tilt upward around the rotating rod through the L-shaped tie rod. At this time, the rotating scraper has no contact with the metal debris at the bottom. When the L-shaped tie rod moves outward, the L-shaped tie rod first pulls the fixed bracket and the rotating scraper, forcing the end of the rotating scraper to contact the top of the sliding frame. Along with the outer wall of the L-shaped tie rod, the rotating scraper will scrape off the impurities remaining on the top of the sliding frame and discharge the equipment outward. Through the application of the above components, it is effective to prevent the accumulation of impurities on the top of the sliding frame. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1, please refer to Figure 1 - Figure 8 This invention relates to a bridge frame cutting machine tool, comprising a support frame 13, a sliding frame 14 slidably connected to the top of the support frame 13, an electric push rod 15 fixedly connected to the side wall of the support frame 13, a fixing block 16 fixedly connected to the top of the sliding frame 14, a bracket 17 fixedly connected to the top of the fixing block 16, an electric push rod 18 fixedly connected to the top of the bracket 17, and a cutter 19 fixedly connected to the output end of the electric push rod 18. The machine tool also includes: Contact mechanism 1 is fixedly connected to the top of fixed block 16 and cooperates with electric push rod 15 to drive sliding frame 14 to slide along the outer track of support frame 13; Expansion mechanism 2 is fixedly connected to the inner wall of contact mechanism 1. When electric push rod 15 retracts, expansion mechanism 2 adapts to reduce the contact area between expansion mechanism 2 and cable tray. Auxiliary mechanism 3 is fixedly connected to the outer wall of contact mechanism 1. Electric push rod 15 drives auxiliary mechanism 3 to deform through contact mechanism 1. Before use, it is necessary to ensure that the cable tray passes through the contact mechanism 1 and that the bend at the top of the cable tray is hooked to the inside of the contact mechanism 1.
[0022] Contact mechanism 1 includes: The tension component 11 is slidably connected to the outer wall of the sliding frame 14 via a linkage; The linkage includes a slide groove 111 formed on the outer wall of the sliding frame 14, and a sliding block 112 slidably connected to the inner wall of the slide groove 111. Positioning component 12 is fixedly connected to the top of fixed block 16 via a movable component; The movable component includes a movable plate 121 fixedly connected to the top of the fixed block 16. A cavity 122 is provided in the inner wall of the movable plate 121, and a flow groove 123 is provided in the side wall of the cavity 122. During use, it is necessary to ensure that the bent position at the top of the cable tray is in a sliding state with the recessed position at the top of the flow channel 123, and that the inner wall of the cable tray remains tightly attached to the inner wall of the flow channel 123 when the expansion mechanism 2 expands.
[0023] Expansion mechanism 2 includes: The shielding component 21 is fixedly connected to the inner wall of the cavity 122 by a limiting member; The limiting component includes an L-shaped baffle 212 that is slidably connected to the inner wall of the cavity 122; Push component 22 is fixedly connected to the inner wall of cavity 122 via a pressure-applying component; The pressure-applying component includes a rotating rod 221 rotatably connected to the inner wall of the cavity 122, and a rotating rod 222 rotatably connected to the other end of the rotating rod 221. The end of the rotating rod 222 away from the rotating rod 221 is rotatably connected to the bottom of the L-shaped baffle 212. Under normal conditions, rotating rod 1 221 and rotating rod 222 are in a folded state. At this time, there is no overlap between L-shaped baffle 212 and flow channel 123. However, when the auxiliary mechanism 3 drives rotating rod 1 221 to rotate, rotating rod 1 221 and rotating rod 222 will rotate and push L-shaped baffle 212 to move outward. At this time, L-shaped baffle 212 will overlap with flow channel 123.
[0024] Auxiliary mechanism 3 includes: Linkage component 31 is fixedly connected to the top of sliding block 112 by a tensioning member; The tensioning component includes a linkage rod 311 fixedly connected to the top of the sliding block 112, a U-shaped frame 312 fixedly connected to the side wall of the linkage rod 311, and a folding rod 313 rotatably connected to the inner wall of the U-shaped frame 312. Cleaning component 32 is slidably connected to the top of sliding block 112 via a positioning element; The positioning component includes an L-shaped pull rod 321 fixedly connected to the side wall of the sliding block 112, a movable block 322 slidably connected to the top of the sliding frame 14, a rotating rod 323 fixedly connected to the side wall of the movable block 322, and a rotating scraper 324 rotatably connected to the outer wall of the rotating rod 323. When the sliding block 112 slides along the inner wall of the groove 111, the sliding block 112 will drive the rotating scraper 324 to rotate around the rotating rod 323 via the L-shaped tie rod 321.
[0025] Example 2, please refer to Figure 8 - Figure 10 The present invention is a bridge frame cutting and processing machine tool. Based on Example 1, the pulling component 11 includes a mounting plate 113 fixedly connected to the bottom of the sliding block 112, and the output end of the electric push rod 15 is fixedly connected to the outer wall of the mounting plate 113. Among them, cable trays are mostly made of thin metal sheets by roll forming. Due to the influence of the material, they can produce small deformations. When the angle between rotating rod 1 221 and rotating rod 222 reaches 180 degrees, the contact pressure between L-shaped baffle 212 and the outer wall of the cable tray reaches its maximum. When it exceeds 180 degrees, the pressure between L-shaped baffle 212 and the cable tray will decrease, but the outer wall of L-shaped baffle 212 and the outer wall of the cable tray will still be in contact.
[0026] Positioning component 12 includes a cutting groove 124 formed on the top of the movable plate 121; Utilizing the characteristic of the sliding block 112 sliding along the inner wall of the groove 111, when the sliding block 112 is pushed inward, the sliding block 112 forces the sliding block 2 314 to tilt upward around the rotating rod 323 via the L-shaped pull rod 321. At this time, the rotating scraper 324 does not contact the metal debris at the bottom. When the L-shaped pull rod 321 moves outward, the L-shaped pull rod 321 first pulls the fixed bracket 325 and the rotating scraper 324, forcing the end of the rotating scraper 324 to contact the top of the sliding frame 14. Along with the outer wall of the L-shaped pull rod 321, the rotating scraper 324 will scrape off the impurities remaining on the top of the sliding frame 14 and discharge the equipment outward. Through the application of the above components, it is effective to prevent the accumulation of impurities on the top of the sliding frame 14.
[0027] The shielding assembly 21 includes a telescopic rod 211 fixedly connected to the inner wall of the cavity 122, and the other end of the telescopic rod 211 is fixedly connected to the side wall of the L-shaped baffle 212. Utilizing the regular expansion characteristic of the L-shaped baffle 212, after the equipment completes the cutting, the L-shaped baffle 212 will move away from the outer wall of the cable tray. After the cutter 19 completes the cutting of the outer wall of the cable tray, residual metal debris will remain. As the distance between the L-shaped baffle 212 and the flow channel 123 increases, the debris remaining inside will become loose due to the reduced contact area with the surrounding area. Finally, the debris will fall to the top of the sliding frame 14 under the push of the subsequent cable tray. Through the application of the above components, it is effectively prevented that residual metal debris inside the moving plate 121 will increase the friction between the cable tray and the equipment, affecting the efficiency of the cable tray passing through the flow channel 123.
[0028] The pushing component 22 includes a blocking block 223 fixedly connected to the side wall of the rotating rod 221; Utilizing the characteristics of the rotating rod 221 and rotating rod 222 to push the L-shaped baffle 212, an obstruction block 223 is provided inside the equipment. When the L-shaped baffle 212 moves outward to its maximum angle of 181 degrees, as... Figure 8As shown, when the top of the L-shaped baffle 212 is cut by the cutter 19, the pressure will be transmitted to the rotating rod 222. During this process, due to the presence of the telescopic rod 211, the L-shaped baffle 212 can only slide along the preset path. However, if the L-shaped baffle 212 slides, the rotating rod 221 and the rotating rod 222 need to be in a folded state. Since the angle between the rotating rod 221 and the rotating rod 222 is 181 degrees, when the top of the L-shaped baffle 212 is pressed, the rotating rod 221 and the rotating rod 222 will rotate towards the obstruction block 223. However, the rotating rod 221 and the rotating rod 222 cannot rotate due to the obstruction block 223. Therefore, after the top of the L-shaped baffle 212 is pressed, the pressure will be trapped inside the moving plate 121. Through the application of the above components, the pressure of the cutter 19 is prevented from being transmitted to the mounting plate 113 through the rotating rod 221 and the linkage component 31, which would affect the moving efficiency of the sliding frame 14 and cause differences in the cutting length.
[0029] The linkage component 31 includes a second sliding block 314 rotatably connected to both ends of the folding rod 313, a sliding rod 315 rotatably connected to the inner wall of the second sliding block 314, and the outer wall of the sliding rod 315 rotatably connected to the outer wall of the first rotating rod 221. Subsequently, the electric actuator 15 generates an extending force, forcing the sliding frame 14 to slide to the other end. At this time, the pressure generated by the electric actuator 15 forces the mounting plate 113 to reset, and simultaneously forces the linkage rod 311 to drive the sliding blocks 314 at both ends to reset. The sliding rod 315 then drives the rotating rod 221 and the rotating rod 222 back into a bent state. Figure 8 The state changes to Figure 5 In this state, rotating rod 222 will cause L-shaped baffle 212 to retract. Through the application of the above components, when the cable tray slides along the inner wall of the flow channel 123, L-shaped baffle 212 will move away from the outer wall of the cable tray, preventing the metal plate on the outer wall of the cable tray from affecting the cutting efficiency of the equipment. When the mounting plate 113 is pulled outward, the linkage rod 311 will cause the folding rod 313 to fold. The folding rod 313 will cause the two sliding blocks 314 to slide. The sliding blocks 314, through the sliding rod 315, force the included angle between rotating rod 221 and rotating rod 222 to increase, eventually reaching 181 degrees.
[0030] The cleaning assembly 32 includes a fixed bracket 325 fixedly connected to the top of the rotating scraper 324, and the outer wall of the L-shaped pull rod 321 is rotatably connected to the inner wall of the fixed bracket 325. The outer wall of the sliding rod 315 is rotatably connected to the bent outer walls of the rotating rod 1 221 and the rotating rod 222; Subsequently, the electric actuator 15 generates an extending force, forcing the sliding frame 14 to slide to the other end. At this time, the pressure generated by the electric actuator 15 forces the mounting plate 113 to reset, and simultaneously forces the linkage rod 311 to drive the sliding blocks 314 at both ends to reset. The sliding rod 315 then drives the rotating rod 221 and the rotating rod 222 to return to their bent state. Figure 8 The state changes to Figure 5 In this state, the rotating rod 222 will drive the L-shaped baffle 212 to retract. Through the application of the above components, when the cable tray slides along the inner wall of the flow channel 123, the L-shaped baffle 212 will move away from the outer wall of the cable tray, preventing the metal plate on the outer wall of the cable tray from affecting the cutting efficiency of the equipment.
[0031] A specific application of this embodiment is as follows: During use, it is necessary to ensure that the bending position at the top of the cable tray and the recessed position at the top of the flow groove 123 are in a sliding state. When the electric push rod 15 drives the sliding frame 14 to move along the outer wall of the support frame 13, when the moving speed of the sliding frame 14 is equal to the sliding speed of the cable tray, the electric push rod 18 pushes the cutter 19 into the inner wall of the cutting groove 124 and performs a cutting process on the cable tray. Utilizing the regular extension and retraction characteristics of the electric actuator 15, when the electric actuator 15 is running, it first drives the mounting plate 113 and the sliding block 112 to slide a short distance along the inner wall of the slide groove 111. When the mounting plate 113 and the sliding block 112 move towards the electric actuator 15, the sliding frame 14 will move at the same speed as the cable tray. The mounting plate 113 will pull the sliding block 112 and the linkage rod 311 to move outward synchronously. The linkage rod 311 drives the folding rod 313 to fold. The folded folding rod 313 will drive the two sliding blocks 314 to slide. The sliding blocks 314, through the sliding rod 315, force the angle between the rotating rod 221 and the rotating rod 222 to widen, eventually reaching 181 degrees. During this process, the rotating rod 222 will push the L-shaped baffle 212 along the outer wall of the cable tray and form a clamping state on the outer wall of the cable tray, presenting as... Figure 7 In the T-state, the cutter 19 then cuts downwards to complete the basic cutting process; subsequently, the electric actuator 15 generates an extending force, forcing the sliding frame 14 to slide to the other end. At this time, the pressure generated by the electric actuator 15 will force the mounting plate 113 to reset, and simultaneously force the linkage rod 311 to drive the sliding blocks 314 at both ends to reset, and through the sliding rod 315, drive the rotating rod 221 and the rotating rod 222 to return to the bent state, from Figure 8 The state changes to Figure 5 In this state, the rotating rod 222 will drive the L-shaped baffle 212 to retract. Through the application of the above components, when the cable tray slides along the inner wall of the flow channel 123, the L-shaped baffle 212 will move away from the outer wall of the cable tray, preventing the metal plate on the outer wall of the cable tray from affecting the cutting efficiency of the equipment.
[0032] Utilizing the characteristics of the rotating rod 221 and rotating rod 222 to push the L-shaped baffle 212, an obstruction block 223 is provided inside the equipment. Specifically, when the L-shaped baffle 212 moves outward to its maximum angle of 181 degrees, as... Figure 8 As shown, when the top of the L-shaped baffle 212 is cut by the cutter 19, the pressure will be transmitted to the rotating rod 222. During this process, due to the presence of the telescopic rod 211, the L-shaped baffle 212 can only slide along the preset path. However, if the L-shaped baffle 212 slides, the rotating rod 221 and the rotating rod 222 need to be in a folded state. Since the angle between the rotating rod 221 and the rotating rod 222 is 181 degrees, when the top of the L-shaped baffle 212 is pressed, the rotating rod 221 and the rotating rod 222 will rotate towards the obstruction block 223. However, the rotating rod 221 and the rotating rod 222 cannot rotate due to the obstruction block 223. Therefore, after the top of the L-shaped baffle 212 is pressed, the pressure will be trapped inside the moving plate 121. Through the application of the above components, the pressure of the cutter 19 is prevented from being transmitted to the mounting plate 113 through the rotating rod 221 and the linkage component 31, which would affect the moving efficiency of the sliding frame 14 and cause differences in the cutting length.
[0033] Utilizing the regular expansion characteristic of the L-shaped baffle 212, after the equipment completes the cutting, the L-shaped baffle 212 will move away from the outer wall of the cable tray. After the cutter 19 completes the cutting of the outer wall of the cable tray, metal debris will remain. As the distance between the L-shaped baffle 212 and the flow channel 123 increases, the debris remaining inside will become loose due to the reduced contact area with the surrounding area. Finally, the debris will fall to the top of the sliding frame 14 under the push of the subsequent cable tray. Through the application of the above components, it is effectively prevented that metal debris remains inside the moving plate 121. Debris increases the friction between the cable tray and the equipment, affecting the efficiency of the cable tray passing through the flow channel 123.
[0034] Utilizing the characteristic of the sliding block 112 sliding along the inner wall of the groove 111, when the sliding block 112 is pushed inward, the sliding block 112 forces the sliding block 2 314 to tilt upward around the rotating rod 323 via the L-shaped pull rod 321. At this time, the rotating scraper 324 does not contact the metal debris at the bottom. When the L-shaped pull rod 321 moves outward, the L-shaped pull rod 321 first pulls the fixed bracket 325 and the rotating scraper 324, forcing the end of the rotating scraper 324 to contact the top of the sliding frame 14. Along with the outer wall of the L-shaped pull rod 321, the rotating scraper 324 will scrape off the impurities remaining on the top of the sliding frame 14 and discharge the equipment outward. Through the application of the above components, it is effective to prevent the accumulation of impurities on the top of the sliding frame 14.
