Description

Technical Field

[0001] The utility model belongs to the field of cutting machines, and in particular relates to a polystyrene board cutting machine. Background Art

[0002] Styrene board is a plastic board made of styrene as the base material. It is a good cushioning material because of its light weight and flexibility, stable structure, not easy to deform and crack, and able to withstand large forces. Therefore, when packing and shipping furniture, use stylus board as a cushioning material for packaging and protection to prevent the furniture parts from being damaged by bumps.

[0003] The polystyrene board is a board with fixed size specifications. When using polystyrene board to pack various parts of furniture, it is necessary to cut the polystyrene board according to the size specifications of each part of the furniture so that the polystyrene board can better fit the surface of each part of the furniture and improve its protective effect.

[0004] Styrene boards are often cut by styrene board cutting machines. The currently used styrene board cutting machines usually manually hold the styrene boards tight after supporting them to prevent them from moving and affecting the cutting accuracy. However, manually holding the styrene boards tight is laborious and can easily cause the styrene boards to shift, and there are certain risks in use. When the styrene boards are clamped with the help of a clamp, there are technical problems such as inconvenience in operation and affecting the cutting efficiency. At the same time, the styrene board cutting machine uses an electric heating cutting wire to perform thermal cutting on the styrene boards. During the cutting process, irritating and harmful gases and impurities will be generated, which will affect the working environment. Utility Model Content

[0005] The utility model provides a benzene board cutting machine to solve the technical problems of inconvenient cutting and fixing of benzene boards and cutting affecting environmental quality. The benzene boards are fixed by negative pressure adsorption, and the cutting gas, dust impurities, etc. are sucked out during the cutting process, so that the cutting is accurate and reliable, and the working environment is guaranteed to be hygienic.

[0006] The technical solution adopted by the utility model is as follows: a benzene board cutting machine is provided, comprising a chassis with an open top, an operating table is fixedly installed on the top of the chassis, and an electric hot cutting wire is arranged above the operating table along the width direction; through holes are evenly arranged on the top surface of the operating table, and the through holes are connected to the chassis; an open tray is detachably installed on the top of the chassis, and the top surface of the tray abuts against the bottom surface of the operating table, and the through holes are connected to the tray, and the tray is filled with filter materials; an air pump is installed in the chassis, and the air pump is connected to the tray through a pipeline; a plurality of horizontal support bars are arranged on the top of the operating table along the length direction, the support bars are horizontally slidably installed on the top of the operating table, and the support bars are abutted and locked with the operating table by means of locking pieces; adsorption holes are evenly arranged on the top of the support bars along the length direction, and a docking groove is opened at the bottom end of the support bars, and the docking groove is connected to the through hole and the adsorption hole; a horizontal track is vertically slidably installed on the front end of the chassis, a bracket is horizontally movable in the horizontal track, and the bracket is fixedly connected to the electric hot cutting wire.

[0007] After the support bar moves along the operating table, the benzene board is supported, and the air pump of the chassis sucks the airflow in the tray through the pipeline to suck the airflow on the operating table through the through hole, and the support bar covers the through hole, so that the benzene board is adsorbed and fixed through the adsorption hole on the top of the support bar, ensuring the stability and cutting accuracy of the benzene board cutting, and then the operating bracket drives the electric heating cutting wire to move horizontally and vertically on the operating table to cut the benzene board. The operation is simple, and during the cutting process of the benzene board, the support bar supports the benzene board and maintains a gap between the operating table, so that the through hole drives the airflow around the benzene board to flow, thereby sucking the dust, impurities, etc. generated during the cutting process, ensuring the clean and hygienic working environment, and the tray is filled with filter material, the filter material filters the impurities in the airflow to avoid damage to the air pump and improve the safety of use.

[0008] To further optimize the technical solution, a door that opens outward is provided on the rear side of the chassis, heat dissipation holes are evenly arranged on the door, and the chassis can be detachably installed through guide rails and trays.

[0009] After opening the box door, the tray can be installed and disassembled along the guide rails and the chassis, which is flexible to use. The airflow generated by the operation of the air pump is discharged outward through the heat dissipation holes of the box door to ensure the consistency of the air pressure inside and outside the chassis. The air circulation in the chassis dissipates heat for components such as the air pump, ensuring safety in use.

[0010] To further optimize the technical solution, the guide rail includes slide bars fixedly installed at two opposite ends of the inner wall of the chassis and slide grooves opened at two opposite ends of the outer wall of the tray, the slide grooves are slidably plugged into the slide bars, and elastic protrusions are evenly arranged on the slide bars, which abut against the inner walls of the slide grooves.

[0011] The slide groove on the tray is slidably installed with the slide bar in the chassis, making it easy to pull out, assemble and disassemble. When the slide bar supports the tray, as the slide groove and the slide bar are plugged in, the protrusions increase the friction between the slide bar and the slide groove to limit the random movement of the tray, and the airflow is sucked smoothly and stably, ensuring reliability of use.

[0012] To further optimize the technical solution, both the front and rear parts of the top of the operating table are provided with connecting openings along the length direction, and the locking members are slidably connected to the connecting openings.

[0013] When the locking piece slides along the connection port, it drives the support bar to move along the operating table, and after the locking piece is locked in the connection port, the position of the support bar is constrained and positioned, and the use is flexible and simple.

[0014] To further optimize the technical solution, the locking member includes docking rods fixedly installed at the front and rear parts of the bottom end of the support bar, the docking rods are slidably connected to the connecting port, and the bottom end of the docking rod passes through the operating table and is threadedly connected with a locking nut.

[0015] The docking rods are arranged on both sides of the bottom end of the support bar and are inserted into the connecting port on the operating table, so that the support bar can be easily moved. The docking rods pass through the bottom end of the operating table to facilitate the threaded connection of the locking nut. After the locking nut abuts against the bottom end of the operating table, its contact friction is increased to constrain the docking rods to move along the connecting port, thereby locking the position of the support bar, which is easy to operate.

[0016] To further optimize the technical solution, at least two vertical slide rails are fixedly installed at the front end of the chassis, sliders are slidably installed in the vertical slide rails, and the sliders are fixedly installed on the horizontal rails by means of connecting pieces.

[0017] The horizontal track is connected to the slider in the vertical track, so that it can be lifted and lowered along the vertical track. The vertical tracks are arranged on both sides of the horizontal track, so that it can be lifted and lowered smoothly and stably.

[0018] To further optimize the technical solution, the connecting member includes a tightening bolt threadedly connected to the horizontal track, the tightening bolt passes through the horizontal track, and is threadedly connected to the slider.

[0019] The horizontal track is assembled with the slider through the tightening bolts, so that it can be raised and lowered along the vertical track. The friction between the horizontal track and the vertical track can be adjusted by adjusting the thread engagement amount between the tightening bolts and the slider. This ensures the stable lifting of the horizontal track while providing friction resistance to the horizontal track, limiting the random movement of the horizontal track, making it safer and more reliable to use.

[0020] To further optimize the technical solution, a threaded groove is provided on the outer wall of the slider, a spring washer is provided in the threaded groove, and the tightening bolt is threadably connected to the threaded groove and abuts against the spring washer.

[0021] The threaded engagement between the jacking bolt and the threaded groove on the slider adjusts the contact friction between the horizontal track and the vertical track. The jacking bolt pushes the spring washer in the threaded groove to deform, causing it to generate a reaction force, which pushes the jacking bolt to engage tightly with the threaded groove to prevent the jacking bolt from loosening, making it firm and reliable to use.

[0022] To further optimize the technical solution, a rubber pad is fixedly sleeved on the inner wall of the docking groove, and the bottom end of the rubber pad protrudes from the bottom end of the support bar and abuts against the top end of the operating table.

[0023] The support bar is locked on the operating table and covers the through hole. After the docking groove is connected with the through hole, the rubber pad sleeved in the docking groove abuts against the operating table, improving the sealing of the connection between the docking groove and the through hole, so that the support bar can adsorb and fix the benzene board firmly and reliably.

[0024] The beneficial effects of the utility model are:

[0025] 1. When the locking nut and the bottom of the operating table are loose, the support bar drives the connecting port of the docking rod to slide, so as to adjust the supporting position of the benzene board according to the specifications of the benzene board, and the operation is simple. Then tighten the locking nut to increase the friction between it and the operating table, and then lock the position of the support bar to make it stable in supporting the benzene board. When the support bar covers the through hole and is connected with the docking groove, the rubber pad improves the sealing of the docking and ensures the smoothness of the airflow of the adsorption hole on the top of the support bar;

[0026] 2. When the air pump in the chassis is running, it sucks the airflow in the tray, so as to adsorb and fix the benzene board supported by the support bar through the adsorption holes, and the support bar maintains a gap between the benzene board and the operating table, so that the air pump can suck the airflow around the benzene board through the through holes, thereby sucking the dust and impurities in the benzene board cutting process, ensuring the hygiene of the working environment and improving the safety of operation;

[0027] 3. When the sucked airflow enters the tray, the tray is filled with filter material to filter impurities in the airflow, thereby preventing the impurities from damaging the air pump. The airflow discharged from the air pump is discharged outward through the heat dissipation holes on the rear door of the chassis to ensure the consistency of pressure inside and outside the chassis. The airflow velocity in the chassis is increased, and the air pump and other components are cooled to ensure safe and stable operation.

[0028] 4. After the support bar adsorbs and fixes the benzene board, the horizontal track drives the bracket to rise and fall along the vertical track on the chassis, and the bracket drives the electric hot cutting wire to move horizontally along the horizontal track, so as to cut the benzene board according to processing requirements. The horizontal track and the vertical track adjust their contact friction through the tightening bolts, so that the lifting and lowering operation of the electric hot cutting wire is stable and reliable.
