Description

Technical Field

[0001] This invention belongs to the field of cable tray cutting and manufacturing technology, and specifically relates to a cable tray cutting device for electrical engineering installation. Background Technology

[0002] Cable trays are available in various structures, including trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. For cable trays installed outdoors, especially near the sea or in corrosive areas, the material must possess properties such as corrosion resistance, moisture resistance, good adhesion, and high impact resistance. In actual installation, cable trays often need to be cut to facilitate better installation.

[0003] Currently, when cutting cable trays, most operations involve using ordinary cutting machines without employing specialized clamps to secure them. This lack of stable support and positioning, combined with vibrations from the cutting machine and the cable tray's own weight, easily leads to bending at the edges and corners. This significantly impacts subsequent installation, greatly affecting installation accuracy. Furthermore, cutting cable trays is typically done manually, which requires overcoming greater resistance when cutting at angles. In practice, when the cutting force is large, the cutting machine is prone to shaking. This shaking can directly cause the cutting position to deviate, and the originally planned cutting line may deviate from the predetermined track. As a result, the size and shape of the cut cable tray may not meet the design requirements, thus affecting the progress and quality of the entire project. In addition, most of the waste generated during the cutting process is in the form of pulverized material. During transportation, the pulverized waste is easy to scatter, which not only increases the difficulty of cleaning and collection, but may also cause pollution to the surrounding environment. When it comes to secondary utilization, the irregular shape and small particle size of the waste make it difficult to effectively screen and process, reducing the reuse value of the waste and increasing the possibility of resource waste.

[0004] Therefore, there is an urgent need to provide a cable tray cutting device for electrical engineering installation to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cable tray cutting device for electrical engineering installation.

[0006] The technical solution adopted to solve the above technical problems is: to provide a cable tray cutting device for electrical engineering installation, including a cutting table, a rotating mechanism rotatably connected inside the cutting table, a clamping mechanism fixedly installed on the surface of the rotating mechanism, the clamping mechanism being used to fix and clamp the side wall of the cable tray, the rotating mechanism being used to rotate the fixedly clamped cable tray, and further including;

[0007] A drive mechanism is fixedly installed on the surface of the cutting table. A switching mechanism is hinged to the surface of the drive mechanism. An adjustment mechanism is fixedly installed on the surface of the switching mechanism. A cutting machine and a grinding machine are slidably connected inside the adjustment mechanism. The drive mechanism is used to drive the switching mechanism and the adjustment mechanism to adjust their positions inside the cutting table for cutting different positions of the cable tray. The switching mechanism is used to switch the positions of the cutting machine and the grinding machine inside the switching mechanism. The adjustment mechanism is used to adjust the height of the cutting machine and the grinding machine from the cable tray.

[0008] A collection box is fixedly installed inside the cutting table, and a pressing mechanism is fixedly installed inside the rotating mechanism. The pressing mechanism is used to press the bottom inner wall of the cable tray. An integrating mechanism is fixedly installed inside the cutting table. The integrating mechanism is located below the collection box and is used to integrate the waste residue during cutting into blocks.

[0009] The invention is further configured such that: the surface of the cutting table is provided with symmetrical rotating grooves, the surface of the cutting table is provided with sliding grooves, and symmetrical baffles are fixedly installed in the middle of the cutting table, the baffles being located above the collection box and fixedly connected to the upper surface of the collection box.

[0010] Through the above technical solution, the rotating groove provides space for the rotation of the rotating plate and the annular toothed plate, and can be more stable during rotation. The sliding groove is used for the movement of the slider. The baffle shields the waste during cutting, preventing the waste from splashing and causing injury to workers or objects. After being shielded by the baffle, the waste falls into the collection box.

[0011] The invention is further configured such that: the rotating mechanism includes two rotating plates, each rotating plate having a first through hole inside; an annular toothed plate is fixedly mounted on the surface of the rotating plate; both the rotating plate and the annular toothed plate are rotatably connected inside a rotating groove; the rotating mechanism also includes a first motor, which is fixedly mounted on the surface of the cutting table; a rotating rod is drivenly connected to the output end of the first motor; symmetrical first gears are fixedly mounted on the surface of the rotating rod, and the first gears mesh with the annular toothed plate; a first sprocket is fixedly mounted on the surface of the rotating rod; a fixed platform is fixedly mounted on the surface of one of the rotating plates; a second motor is fixedly mounted on the surface of the fixed platform; and a first threaded rod is drivenly connected to the output end of the second motor.

[0012] With the above technical solution, when it is necessary to cut the side of the cable tray, the first motor is started, and the rotating rod drives the two first gears to rotate. Through the meshing relationship between the first gears and the ring tooth plate, the two rotating plates can rotate, which in turn drives the two clamping mechanisms to rotate together with the cable tray to cut the side of the cable tray. The first through hole is set for the placement of the cable tray. After the cable tray is cut, the second motor is started, and the clamping mechanism on the right side moves to the right on the fixed table surface, so that the cable tray is separated. The cut part of the cable tray can be ground by a grinder.

[0013] The present invention is further configured such that: two clamping mechanisms are provided, one of which is threadedly connected to the surface of a first threaded rod and slidably connected to the surface of a fixed platform. The clamping mechanism includes a clamping platform, the surface of which has a second through hole. The first through hole and the second through hole are on the same horizontal plane. A handle is rotatably connected to the surface of the clamping platform. A first bidirectional lead screw is fixedly installed on the surface of the handle. The first bidirectional lead screw is rotatably connected to the inside of the clamping platform. A symmetrical first clamping plate is threadedly connected to the surface of the first bidirectional lead screw. A second sprocket is fixedly installed at the end of the first bidirectional lead screw. A second bidirectional lead screw is rotatably connected to the inside of the clamping platform. A third sprocket is fixedly installed at the end of the second bidirectional lead screw. A first chain meshes with the surfaces of the second sprocket and the third sprocket. A second clamping plate is threadedly connected to the surface of the second bidirectional lead screw.

[0014] With the above technical solution, the cable tray is inserted into the second through hole inside the clamping platform through the first through hole. At this time, when the handle is turned, the first bidirectional screw rotates, and the two first clamping plates approach and fit against the outer wall of the cable tray. At the same time, the second sprocket at the end of the first bidirectional screw rotates. Through the meshing relationship between the first chain and the second and third sprockets, the second bidirectional screw can rotate accordingly. The two second clamping plates approach and fit against the inner wall of the cable tray. The first and second clamping plates cooperate to squeeze and fix the cable tray, preventing the cable tray from shifting during cutting. Moreover, the first and second clamping plates can clamp cable trays of different sizes.

[0015] The present invention is further configured such that: the first clamping plate and the second clamping plate are slidably connected inside the second through hole; the threads on the surfaces of the first bidirectional lead screw and the second bidirectional lead screw are opposite in direction; the inner wall of the second through hole is provided with symmetrical receiving grooves; the first clamping plate is slidably connected inside the receiving grooves; the surface of the clamping platform is provided with multiple insertion holes arranged in a ring; and pins are movably inserted into both the insertion holes and the handle.

[0016] With the above technical solution, the width of the first through hole and the second through hole are the same, which is used for the placement of the cable tray. The first clamping plate and the second clamping plate on the same side clamp the side of the cable tray, so that the cable tray can be fixed inside the first through hole and the second through hole. The receiving groove provides space for the movement of the first clamping plate. The first bidirectional screw is kept fixed by the cooperation of the pin and the socket. The first clamping plate and the second clamping plate can form a stable and continuous clamping operation for the cable tray.

[0017] The present invention is further configured such that: the driving mechanism includes a third motor, the third motor is fixedly mounted on the surface of the cutting table, the output end of the third motor is drivenly connected to a second threaded rod, the surface of the second threaded rod is threadedly connected to a slider, the slider is slidably connected inside a groove, the surface of the slider is rotatably connected to a cylinder, and the end of the cylinder is fixedly mounted with a sleeve.

[0018] With the above technical solution, when it is necessary to cut different positions of the cable tray, the third motor is started, the second threaded rod rotates, thereby moving the slider inside the cutting table, and further driving the cutting machine to the position to be cut. When it is necessary to cut the cable tray at an inclined angle, the cylinder is started, the connecting plate is squeezed to make the connecting plate rotate, and the cutting machine is driven to rotate to the required angle to carry out the cutting work.

[0019] The present invention is further configured such that: the switching mechanism includes a connecting plate, the connecting plate is hinged to the slider, a fourth motor is fixedly mounted on the surface of the connecting plate, a second gear is fixedly mounted on the end of the transmission shaft of the fourth motor, a third gear is rotatably connected inside the connecting plate, the second gear meshes with the third gear, symmetrical connecting rods are fixedly connected to the surface of the third gear, a limit ring is fixedly mounted on the end of the connecting rod, symmetrical mounting blocks are fixedly mounted on one side of the surface of the connecting plate, a fixed shaft is fixedly connected in the middle of the mounting blocks, a sleeve is rotatably connected to the surface of the fixed shaft, an annular groove is formed on the lower surface of the connecting plate, and the connecting rod is rotatably connected inside the annular groove.

[0020] With the above technical solution, after the cable tray is cut, when it is necessary to grind the cut area, the fourth motor is started, the second gear rotates, and through meshing with the third gear, the third gear rotates inside the connecting plate. Through the connection of the connecting rod, the positions of the cutting machine and the grinding machine are interchanged. The grinding machine grinds the cut area. When the cylinder presses the connecting plate, the linear motion of the cylinder can be transformed into curvilinear motion through the cooperation of the sleeve and the fixed shaft, increasing the rotation angle of the connecting plate. The setting of the annular groove makes the connecting rod more stable when rotating.

[0021] The invention is further configured such that: the adjustment mechanism includes an adjustment plate, the adjustment plate is rotatably connected to the lower surface of the connecting plate, a fixing block is fixedly installed on the surfaces of the cutting machine and the grinding machine, the fixing block is slidably connected inside the adjustment plate, a through groove is opened inside the fixing block, the connecting rod and the limiting ring are slidably connected inside the through groove, a rack is fixedly installed on the surface of the fixing block, a fifth motor is fixedly installed on the surface of the adjustment plate, a fourth gear is fixedly installed at the end of the transmission shaft of the fifth motor, one side of the fourth gear meshes with the rack on the surface of the fixing block on the cutting machine, and the other side of the fourth gear meshes with the rack on the surface of the fixing block on the grinding machine.

[0022] Through the above technical solution, the adjustment mechanism is used to adjust the height of the cutting machine and the grinding machine. After the cable tray is fixed, the fifth motor is started, and the fourth gear rotates. Through meshing with the two racks, the fixed block on one side can drive the cutting machine to descend for cutting work, while the fixed block on the other side drives the grinding machine to rise. After the cutting work is completed, the adjustment mechanism swaps the positions of the cutting machine and the grinding machine, and the fifth motor is started again. The grinding machine descends to the cutting position of the cable tray for grinding work, while the cutting machine rises. When the fixed block is raised and lowered, the connecting rod and the limiting ring slide inside the through groove, making the fixed block more stable when it is raised and lowered.

[0023] The invention is further configured such that: the pressing mechanism includes a horizontal plate, the horizontal plate is fixedly installed inside the first through hole, a screw is threadedly connected to the surface of the horizontal plate, a pressing plate is threadedly connected to the surface of the horizontal plate, and symmetrical guide rods are fixedly installed on the surface of the pressing plate, the guide rods being slidably connected inside the horizontal plate.

[0024] Through the above technical solution, the pressing mechanism presses the bottom inner wall of the cable tray. By turning the screw, the pressing plate moves down to the bottom inside of the cable tray, which again fixes the cable tray. The guide rod makes the pressing plate more stable when it moves.

[0025] The present invention is further configured such that: the integration mechanism includes an integration box, the integration box is fixedly installed on the lower surface of the collection box, a third threaded rod is rotatably connected inside the integration box, an extrusion plate is threadedly connected to the surface of the third threaded rod, the extrusion plate is slidably connected inside the integration box, a fourth sprocket is fixedly installed at the end of the third threaded rod, a second chain is meshed between the surface of the first sprocket and the surface of the fourth sprocket, and a box door is hinged to the lower surface of the integration box.

[0026] Through the above technical solution, the waste residue falls into the integration box through the collection box. When the rotating rod rotates, the first sprocket rotates. Through the meshing relationship between the second chain and the first and fourth sprockets, the third threaded rod is driven to rotate, so that the extrusion plate extrudes and integrates the waste residue inside the integration box into blocks, which is convenient for transportation and subsequent secondary use.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This invention is provided with two clamping mechanisms and two pressing mechanisms. The two clamping mechanisms clamp and fix the sides of the cable tray, and the pressing mechanisms press and fix the bottom inner wall of the cable tray. This allows the cable tray to remain fixed during cutting, reducing the occurrence of bending. After cutting, the distance between the two clamping mechanisms can be adjusted so that there is a distance between the two sections of the cable tray after cutting, which facilitates the grinding work of the grinding machine on the cut part and further improves the subsequent installation accuracy.

[0029] 2. The present invention is equipped with a rotating mechanism and a cylinder. The rotating mechanism can rotate the fixed cable tray so that the side of the cable tray is in an open state. When it is necessary to make an inclined angle cut, the cutting machine can be adjusted to an inclined position when the cylinder is started to cut the cable tray, avoiding the shaking phenomenon of the cutting machine caused by manual cutting, and improving the progress and quality of the project.

[0030] 3. The present invention is equipped with an integration mechanism. When the rotating mechanism rotates the cable tray, the integration mechanism can integrate the waste residue that falls into the integration box. The waste residue is squeezed into blocks and can be taken out, which is convenient for subsequent handling and reduces air pollution. The block-shaped waste residue can be quickly screened and processed during secondary utilization, avoiding resource waste. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0043] Please see Figures 1-10 This application provides a cable tray cutting device for electrical engineering installation, including a cutting table 1, a rotating mechanism 2 rotatably connected inside the cutting table 1, and a clamping mechanism 3 fixedly installed on the surface of the rotating mechanism 2. The clamping mechanism 3 is used to fix and clamp the side wall of the cable tray, and the rotating mechanism 2 is used to rotate the fixedly clamped cable tray.

[0044] like Figure 3 and Figure 4As shown, the surface of the cutting table 1 is provided with symmetrical rotating grooves 11 and sliding grooves 12. Symmetrical baffles 13 are fixedly installed in the middle of the cutting table 1. The baffles 13 are located above the collection box 7 and are fixedly connected to the upper surface of the collection box 7.

[0045] In this embodiment, the rotating groove 11 provides space for the rotation of the rotating plate 21 and the annular toothed plate 23, and can be more stable during rotation. The sliding groove 12 is used for the movement of the slider 43. The baffle 13 shields the waste residue during cutting to prevent the waste residue from splashing and causing injury to workers or objects. After being shielded by the baffle 13, the waste residue falls into the collection box 7.

[0046] like Figure 2 and Figure 3 As shown, the rotating mechanism 2 includes two rotating plates 21. The rotating plates 21 have a first through hole 22 inside. An annular toothed plate 23 is fixedly installed on the surface of the rotating plates 21. The rotating plates 21 and the annular toothed plate 23 are rotatably connected inside the rotating groove 11. The rotating mechanism 2 also includes a first motor 24. The first motor 24 is fixedly installed on the surface of the cutting table 1. The output end of the first motor 24 is drivenly connected to a rotating rod 25. A symmetrical first gear 26 is fixedly installed on the surface of the rotating rod 25. The first gear 26 meshes with the annular toothed plate 23. A first sprocket 27 is fixedly installed on the surface of the rotating rod 25. A fixed platform 28 is fixedly installed on the surface of one of the rotating plates 21. A second motor 29 is fixedly installed on the surface of the fixed platform 28. The output end of the second motor 29 is drivenly connected to a first threaded rod 201.

[0047] In this embodiment, when it is necessary to cut the side of the cable tray, the first motor 24 is started, and the rotating rod 25 drives the two first gears 26 to rotate. Through the meshing relationship between the first gears 26 and the ring tooth plate 23, the two rotating plates 21 can rotate, which further drives the two clamping mechanisms 3 to rotate together with the cable tray to cut the side of the cable tray. The first through hole 22 is provided for the placement of the cable tray. After the cable tray is cut, the second motor 29 is started, and the clamping mechanism 3 on the right side moves to the right on the surface of the fixed platform 28, so that the cable tray is separated. The cut part of the cable tray can be polished by the grinder 63.

[0048] like Figure 5As shown, there are two clamping mechanisms 3. One clamping mechanism 3 is threadedly connected to the surface of the first threaded rod 201 and slidably connected to the surface of the fixed platform 28. The clamping mechanism 3 includes a clamping platform 31. A second through hole 32 is opened on the surface of the clamping platform 31. The first through hole 22 and the second through hole 32 are on the same horizontal plane. A handle 33 is rotatably connected to the surface of the clamping platform 31. A first bidirectional lead screw 34 is fixedly installed on the surface of the handle 33. The first bidirectional lead screw 34 is rotatably connected to the inside of the clamping platform 31. A symmetrical first clamping plate 35 is threadedly connected to the surface of the first bidirectional lead screw 34. A second sprocket 36 is fixedly installed at the end of the first bidirectional lead screw 34. A second bidirectional lead screw 37 is rotatably connected to the inside of the clamping platform 31. A third sprocket 38 is fixedly installed at the end of the second bidirectional lead screw 37. A first chain 39 meshes with the surfaces of the second sprocket 36 and the third sprocket 38. A second clamping plate 301 is threadedly connected to the surface of the second bidirectional lead screw 37.

[0049] In a further embodiment, the cable tray is inserted into the second through hole 32 inside the clamping platform 31 through the first through hole 22. At this time, the handle 33 is rotated, the first bidirectional lead screw 34 rotates, and the two first clamping plates 35 approach and fit against the outer wall of the cable tray. At the same time, the second sprocket 36 at the end of the first bidirectional lead screw 34 rotates. Through the meshing relationship between the first chain 39 and the second sprocket 36 and the third sprocket 38, the second bidirectional lead screw 37 can rotate accordingly. The two second clamping plates 301 approach and fit against the inner wall of the cable tray. The first clamping plates 35 and the second clamping plates 301 cooperate to squeeze and fix the cable tray, preventing the cable tray from shifting during cutting. The first clamping plates 35 and the second clamping plates 301 can clamp cable trays of different sizes.

[0050] like Figure 5 and Figure 10 As shown, the first clamping plate 35 and the second clamping plate 301 are slidably connected inside the second through hole 32. The threads on the surfaces of the first bidirectional lead screw 34 and the second bidirectional lead screw 37 are opposite. The inner wall of the second through hole 32 is provided with symmetrical receiving grooves 302. The first clamping plate 35 is slidably connected inside the receiving grooves 302. The surface of the clamping table 31 is provided with multiple insertion holes 303 arranged in a ring. The insertion holes 303 and the handle 33 are both movably inserted with pins 331.

[0051] In this embodiment, the widths of the first through hole 22 and the second through hole 32 are the same, used for placing the cable tray. The first clamping plate 35 and the second clamping plate 301 on the same side clamp the side of the cable tray, so that the cable tray can be fixed inside the first through hole 22 and the second through hole 32. The receiving groove 302 provides space for the movement of the first clamping plate 35. The first bidirectional screw 34 is kept fixed by the cooperation of the pin 331 and the insertion hole 303. The first clamping plate 35 and the second clamping plate 301 can form a stable and continuous clamping operation for the cable tray.

[0052] A drive mechanism 4 is fixedly installed on the surface of the cutting table 1. A switching mechanism 5 is hinged to the surface of the drive mechanism 4. An adjustment mechanism 6 is fixedly installed on the surface of the switching mechanism 5. A cutter 62 and a grinder 63 are slidably connected inside the adjustment mechanism 6. The drive mechanism 4 is used to drive the switching mechanism 5 and the adjustment mechanism 6 to adjust their positions inside the cutting table 1, so as to cut the cable tray at different positions. The switching mechanism 5 is used to switch the positions of the cutter 62 and the grinder 63 inside the switching mechanism 5. The adjustment mechanism 6 is used to adjust the height of the cutter 62 and the grinder 63 from the cable tray.

[0053] like Figure 2 and Figure 8 As shown, the drive mechanism 4 includes a third motor 41, which is fixedly mounted on the surface of the cutting table 1. The output end of the third motor 41 is connected to a second threaded rod 42. The surface of the second threaded rod 42 is threadedly connected to a slider 43. The slider 43 is slidably connected inside the slide groove 12. The surface of the slider 43 is rotatably connected to a cylinder 44. A sleeve 45 is fixedly mounted on the end of the cylinder 44.

[0054] In this embodiment, when it is necessary to cut different positions of the cable tray, the third motor 41 is started, the second threaded rod 42 rotates, thereby causing the slider 43 to move inside the cutting table 1, and further driving the cutting machine 62 to move to the position to be cut. When it is necessary to cut the cable tray at an angle, the cylinder 44 is started, the connecting plate 51 is squeezed to make the connecting plate 51 rotate, and the cutting machine 62 is driven to rotate to the required angle to perform the cutting work.

[0055] like Figure 2 , Figure 3 and Figure 6 As shown, the switching mechanism 5 includes a connecting plate 51, which is hinged to the slider 43. A fourth motor 52 is fixedly mounted on the surface of the connecting plate 51. A second gear 53 is fixedly mounted on the end of the drive shaft of the fourth motor 52. A third gear 54 is rotatably connected inside the connecting plate 51. The second gear 53 meshes with the third gear 54. A symmetrical connecting rod 55 is fixedly connected to the surface of the third gear 54. A limit ring 56 is fixedly mounted at the end of the connecting rod 55. A symmetrical mounting block 57 is fixedly mounted on one side of the surface of the connecting plate 51. A fixed shaft 58 is fixedly connected in the middle of the mounting block 57. A sleeve 45 is rotatably connected to the surface of the fixed shaft 58. An annular groove 59 is opened on the lower surface of the connecting plate 51. The connecting rod 55 is rotatably connected inside the annular groove 59.

[0056] In this embodiment, after the cable tray is cut, when the cut area needs to be polished, the fourth motor 52 is started, the second gear 53 rotates, and through meshing with the third gear 54, the third gear 54 rotates inside the connecting plate 51. Through the connection of the connecting rod 55, the positions of the cutting machine 62 and the polishing machine 63 are interchanged. The polishing machine 63 polishes the cut area. When the cylinder 44 presses against the connecting plate 51, through the cooperation of the sleeve 45 and the fixed shaft 58, the linear motion of the cylinder 44 can be transformed into a curved motion, increasing the rotation angle of the connecting plate 51. The setting of the annular groove 59 makes the connecting rod 55 more stable when rotating.

[0057] like Figure 2 and Figure 6 As shown, the adjustment mechanism 6 includes an adjustment plate 61, which is rotatably connected to the lower surface of the connecting plate 51. Fixing blocks 64 are fixedly installed on the surfaces of both the cutting machine 62 and the grinding machine 63. The fixing blocks 64 are slidably connected inside the adjustment plate 61. A through groove 65 is provided inside the fixing block 64. The connecting rod 55 and the limiting ring 56 are slidably connected inside the through groove 65. A rack 66 is fixedly installed on the surface of the fixing block 64. A fifth motor 67 is fixedly installed on the surface of the adjustment plate 61. A fourth gear 68 is fixedly installed at the end of the transmission shaft of the fifth motor 67. One side of the fourth gear 68 meshes with the rack 66 on the surface of the fixing block 64 on the cutting machine 62, and the other side of the fourth gear 68 meshes with the rack 66 on the surface of the fixing block 64 on the grinding machine 63.

[0058] In this embodiment, the adjustment mechanism 6 is used to adjust the height of the cutting machine 62 and the grinding machine 63. After the cable tray is fixed, the fifth motor 67 is started, and the fourth gear 68 rotates. Through meshing with the two racks 66, the fixing block 64 on one side can drive the cutting machine 62 to descend for cutting work, while the fixing block 64 on the other side drives the grinding machine 63 to rise. After the cutting work is completed, the adjustment mechanism 6 interchanges the positions of the cutting machine 62 and the grinding machine 63, and the fifth motor 67 is started again. The grinding machine 63 descends to the cutting position of the cable tray for grinding work, while the cutting machine 62 rises. When the fixing block 64 is raised and lowered, the connecting rod 55 and the limiting ring 56 slide inside the through groove 65, making the fixing block 64 more stable when it is raised and lowered.

[0059] A collection box 7 is fixedly installed inside the cutting table 1, and a pressing mechanism 8 is fixedly installed inside the rotating mechanism 2. The pressing mechanism 8 is used to press the bottom inner wall of the cable tray. An integrating mechanism 9 is fixedly installed inside the cutting table 1. The integrating mechanism 9 is located below the collection box 7 and is used to integrate the waste residue during cutting into blocks.

[0060] like Figure 3 and Figure 9As shown, the pressing mechanism 8 includes a horizontal plate 81, which is fixedly installed inside the first through hole 22. A screw 82 is threadedly connected to the surface of the horizontal plate 81, and a pressing plate 83 is threadedly connected to the surface of the horizontal plate 81. Symmetrical guide rods 84 are fixedly installed on the surface of the pressing plate 83, and the guide rods 84 are slidably connected inside the horizontal plate 81.

[0061] In this embodiment, the pressing mechanism 8 presses the bottom inner wall of the cable tray. By turning the screw 82, the pressing plate 83 moves down to the bottom inner wall of the cable tray, which again fixes the cable tray. The guide rod 84 makes the pressing plate 83 more stable when it moves.

[0062] like Figure 2 and Figure 3 As shown, the integration mechanism 9 includes an integration box 91, which is fixedly installed on the lower surface of the collection box 7. A third threaded rod 92 is rotatably connected inside the integration box 91. A pressing plate 93 is threadedly connected to the surface of the third threaded rod 92. The pressing plate 93 is slidably connected inside the integration box 91. A fourth sprocket 94 is fixedly installed at the end of the third threaded rod 92. A second chain 95 meshes with the surface of the first sprocket 27 and the fourth sprocket 94. A box door 96 is hinged to the lower surface of the integration box 91.

[0063] In this embodiment, the waste residue falls into the integration box 91 through the collection box 7. When the rotating rod 25 rotates, the first sprocket 27 rotates. Through the meshing relationship between the second chain 95 and the first sprocket 27 and the fourth sprocket 94, the third threaded rod 92 is driven to rotate, so that the extrusion plate 93 extrudes and integrates the waste residue inside the integration box 91 into a block shape, which is convenient for transportation and subsequent secondary use.

[0064] The working principle of this embodiment is as follows: First, the cable tray is inserted into the two first through holes 22 and the second through hole 32. At this time, the handle 33 is turned, and the first bidirectional lead screw 34 rotates. The two first clamping plates 35 approach and fit against the outer wall of the cable tray. At the same time, the second sprocket 36 at the end of the first bidirectional lead screw 34 rotates. Through the meshing relationship between the first chain 39 and the second sprocket 36 and the third sprocket 38, the second bidirectional lead screw 37 can rotate accordingly. The two second clamping plates 301 approach and fit against the inner wall of the cable tray. The first clamping plates 35 and the second clamping plates 301 cooperate to squeeze and fix the cable tray. Tighten the screw 82, press... The pressure plate 83 moves down to the bottom inner wall of the cable tray, fixing the cable tray again. When cutting the cable tray, the third motor 41 is started, and the second threaded rod 42 rotates, causing the slider 43 to move inside the cutting table 1, further moving the cutting machine 62 to the position to be cut. The fifth motor 67 is started, and the fourth gear 68 rotates. Through meshing with the two racks 66, one side of the fixing block 64 can drive the cutting machine 62 down to perform the cutting work, while the other side of the fixing block 64 drives the grinding machine 63 up. After the cutting work is completed, the second motor 29 is started, and the clamping mechanism 3 on the right side is on the surface of the fixing table 28. The cable tray is separated by moving the face to the right. The fourth motor 52 is started, and the second gear 53 rotates. Through meshing with the third gear 54, the third gear 54 rotates inside the connecting plate 51. The positions of the grinder 63 and the cutter 62 are interchanged. The fifth motor 67 is started again, and the grinder 63 descends to the cable tray cutting point to perform grinding work, while the cutter 62 rises. The waste from cutting falls into the integration box 91 through the collection box 7. When the rotating rod 25 rotates, the first sprocket 27 rotates. Through the meshing relationship between the second chain 95 and the first sprocket 27 and the fourth sprocket 94, the third threaded rod 92 is driven. The rotation causes the extrusion plate 93 to extrude and integrate the waste inside the integration box 91 into blocks. When an inclined angle cutting operation is required, the cylinder 44 is activated, and the connecting plate 51 is extruded, causing the connecting plate 51 to rotate. This drives the cutting machine 62 to rotate to the required angle for cutting. When the side of the cable tray needs to be cut, the first motor 24 is activated, and the rotating rod 25 drives the two first gears 26 to rotate. Through the meshing relationship between the first gears 26 and the ring tooth plate 23, the two rotating plates 21 can rotate, further driving the two clamping mechanisms 3 to rotate together with the cable tray to cut the side of the cable tray.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
