Description

Technical Field

[0002] The cutting equipment used for the production of steel truss light composite panels is a kind of cutting equipment, which is used for cutting and separating during the production of steel truss light composite panels. Steel truss light composite panels are a kind of building material made of light composite materials with steel trusses as the skeleton. They are widely used in the fields of construction and decoration. Therefore, the cutting equipment used for the production of steel truss light composite panels is also widely used.

[0003] The Chinese patent with application number "CN202320405684.8" discloses "a composite plate cutting device, relating to the field of composite plate cutting technology, including a workbench, a rectangular groove is provided on the top of the workbench, a conveyor belt is provided at the upper end of the rectangular groove, and a driving shaft and a driven shaft are provided on the inner wall of the conveyor belt". Although it can play the role of "the conveyor belt and the baffle plate can push the composite plate into the cutting part for cutting, and the threaded rod, the movable block and the second motor can adjust the size of the composite plate cutting", when the cutting device is in use, the composite plate cutting usually adopts metal disc for cutting processing, and the steel truss light composite plate is divided into two parts, the steel truss and the composite plate, which are cut separately during cutting processing. Therefore, the steel truss light composite plate is also It is necessary to cut the metal steel truss. When cutting metal materials, frosted discs are used for cutting. As a result, when the equipment cuts the steel truss light composite board, it is necessary to frequently replace the discs to cut the steel truss and the composite board separately, making it inconvenient for the equipment to cut and process the steel truss light composite board. In addition, when the steel truss and the composite board are cut separately, the auxiliary cutting methods are also different. The steel truss cutting requires jet dust removal and cooling, and the composite board cutting requires compression and positioning. The fixed cutting method of the equipment is also inconvenient, and the steel truss and the composite board are cut separately. Moreover, the cutting heights of different discs and the placement heights of the steel truss and the composite board are different. The equipment cannot adjust the cutting height and placement height in time, which also makes the equipment inconvenient for the production and cutting thickness adjustment of the steel truss light composite board.

The rotating rod 27 can adjust the position of the nozzle 28 through the movably installed structure.

[0039] In this embodiment, the guide metal tube 25 is located below the lower pressure frame 22. When the lower pressure frame 22 rotates to the bottom, the composite plate positioning frame 23 is located above the lifting workbench 43. The guide metal tube 25, the pipe joint 26, the rotating rod 27 and the nozzle 28 are internally connected. The air pipe or water pipe is connected through the pipe joint 26, so that air or water passes through the guide metal tube 25 and the rotating rod 27 and is sprayed out from the nozzle 28.

[0040] In this embodiment, the adjustment mechanism 29 includes a handle mounting rod 30, an adjustment handle 31, an adjustment rod 32, a first bevel gear 33, a spline head 34, a second bevel gear 35, a lifting screw 36, a push-pull rod 37, a threaded block 38, a push-pull screw 39 and a spline sleeve 40. The handle mounting rod 30 is fixedly mounted in front of the lower end of the fixed base plate 41, the adjustment rod 32 movably passes through the handle mounting rod 30, the adjustment handle 31 is fixedly mounted on the front end of the adjustment rod 32, the first bevel gear 33 is fixedly sleeved on the outside of the adjustment rod 32, and the spline head 34 is welded to the outer side of the adjustment rod 32. At the rear end, the lifting screw 36 is movably installed at the rear end of the handle mounting rod 30, the second bevel gear 35 is fixedly installed at the lower end of the lifting screw 36, the push-pull rod 37 is movably installed behind the lower end of the fixed base plate 41, the threaded block 38 is movably installed at the front end of the push-pull rod 37, the push-pull screw 39 is threadedly installed at the front end of the threaded block 38, the spline sleeve 40 is fixedly installed at the front end of the push-pull screw 39, and the adjusting rod 32 is a structure that can be pushed and pulled and rotated back and forth, so that the first bevel gear 33 can be meshed and connected with the second bevel gear 35, and the spline head 34 is matched and connected with the spline sleeve 40.

[0041] In this embodiment, the upper end of the lifting screw 36 is inserted into the lifting sleeve 44 and threadedly connected thereto. When the adjusting rod 32 moves forward, the first bevel tooth 33 is meshed and connected with the second bevel tooth 35. When the adjusting rod 32 moves backward, the spline head 34 is inserted into the spline sleeve 40 for cooperation and connection. The rear end of the push-pull rod 37 is inserted into the inner side of the adjusting connecting block 47 for active connection. When the first bevel tooth 33 is meshed and connected with the second bevel tooth 35, the rotation of the adjusting rod 32 drives the second bevel tooth 35 and the lifting screw 36 to rotate. When the spline head 34 is inserted into the spline sleeve 40 for cooperation and connection, the rotation of the adjusting rod 32 drives the spline sleeve 40 and the push-pull screw 39 to rotate.

[0042] It should be noted that the present invention is a cutting device for the production of steel truss light composite panels. When in use, the base frame 1, the front support frame 2 and the rear support frame 3 play a supporting and placing effect. The steel truss light composite panel to be cut is placed on the moving frame 46 on the lifting workbench 43. After the driving motor 6 is powered on, it drives the belt in the belt box 7 to rotate and move, and then drives the spline output shaft 8 to rotate and move through the belt in the belt box 7. Then, the spline output shaft 8 drives the frosted disc 19 or the metal disc 20 to rotate through the connection with the spline mounting block 18, and the steel truss light composite panel to be cut is moved back and forth to contact the rotating frosted disc 19 or the metal disc 20, so as to perform cutting processing;

[0043] When the steel truss and the composite plate are cut in a classified manner, the switching handle 17 is pulled to move to one side, driving the disc mounting rod 16 and the telescopic switching rod 13 to move to one side, and at the same time, the telescopic switching rod 13 pulls the tension spring 12 to expand. After the disc mounting rod 16 moves, the spline mounting block 18 below is separated from the spline output shaft rod 8, and then the switching handle 17 is rotated to drive the disc mounting rod 16 and the telescopic switching rod 13 to rotate, so that the frosted disc 19 or the metal disc 20 switches its position. After the switching handle 17 is released, the telescopic switching rod 13 and the disc mounting rod 16 are pulled back to their original positions by the rebound of the tension spring 12, so that the spline mounting block 18 after switching is connected to the spline output shaft rod 8, thereby realizing the rapid switching of the frosted disc 19 or the metal disc 20 to cooperate with the classified cutting of the steel truss or the composite plate;

[0044] When the frosted disc 19 or the metal disc 20 is switched, the rotation of the telescopic switching rod 13 drives the rotating sleeve 11 and the synchronous switching rod 14 to rotate at the same time. After the synchronous switching rod 14 rotates, it drives the lower pressing frame 22 and the guide metal pipe 25 to switch the upper and lower positions. When the lower pressing frame 22 is located at the bottom, it cooperates with the metal disc 20 to make the composite plate positioning frame 23 press on the composite plate to be cut, and moves and presses through the clamping wheel 24 to facilitate the cutting of the composite plate. When the guide metal pipe 25 is located at the bottom, it cooperates with the frosted disc 19 to make the nozzle 28 on the outside of the rotating rod 27 align with the cutting position, and connects the air pipe through the pipe joint 26, and then the nozzle 28 sprays air to cool and remove dust from the cut steel truss.

[0045] After the frosted disc 19 or the metal disc 20 is switched, the adjusting handle 31 is grasped to push the adjusting rod 32 to move backward, so that the spline head 34 is inserted into the spline sleeve 40 for matching connection. Then, after the adjusting handle 31 and the adjusting rod 32 are rotated, the push-pull screw 39 can be driven to rotate. The rotation of the push-pull screw 39 drives it to move forward and backward through the threaded connection with the threaded block 38, and then drives the push-pull rod 37 to move forward and backward. The forward and backward movement of the push-pull rod 37 pushes the top of the adjusting connecting block 47 to move forward and backward. Therefore, the adjusting connecting block 47 drives the adjusting connecting rod 48 to move up and down. The up and down movement of the adjusting connecting rod 48 then pulls the cutting mounting plate 5 and the rotating mounting rod 4 to rotate, and finally changes the height in front of the cutting mounting plate 5, and adjusts the cutting height of the frosted disc 19 or the metal disc 20, so that frosted discs 19 and metal discs 20 of different sizes are cut and processed at the same height.

[0046] When the steel trusses and composite panels are classified and placed for cutting, the adjusting handle 31 is grasped to push the adjusting rod 32 forward, so that the first bevel gear 33 is meshed and connected with the second bevel gear 35, and the spline head 34 is separated from the spline sleeve 40. Therefore, after the adjusting handle 31 and the adjusting rod 32 are rotated again, the second bevel gear 35 and the lifting screw 36 are driven to rotate through the first bevel gear 33. The rotation of the lifting screw 36 drives its lifting movement through the threaded connection with the lifting sleeve 44, and then drives the lifting workbench 43 to lift and lower, thereby changing the use height of the lifting workbench 43 to cooperate with steel trusses and composite panels of different heights for classified cutting and processing.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
