Description

Technical Field

[0001] This utility model relates to the field of plastic pipe cutting, and in particular to a splash-proof plastic pipe cutting device. Background Technology

[0002] Plastic pipes are produced in long lengths and need to be cut into finished pipes. The cutting process generates a lot of debris, and in some cases, due to poor heat dissipation of the cutting blade, frictional heat accumulates, causing the pipe cut to melt and produce smoke, which pollutes the environment.

[0003] The factory's current simple solution is to place a vacuum cleaner next to the cutting workbench and attach the vacuum head to the vicinity of the cutting disc. However, since the cutting is still in an open environment and the initial speed of the debris is fast, a large amount of flying debris is still splashed out, and the effect is not ideal. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a splash-proof plastic pipe cutting device, including a cutting worktable, the cutting worktable including a table panel, a lifting frame that can move up and down is provided at the lower end of the table panel, a rotatable cutting blade is provided on the lifting frame, an avoidance groove is provided above the rotating seat on the table panel, a pipe pressing mechanism is provided on both sides of the avoidance groove on the upper end of the table panel, a dust suction cover is provided between the two pipe pressing mechanisms, the dust suction cover is fastened above the avoidance groove, a side frame is also provided on one side of the cutting worktable, a dust extraction main pipe is provided at the upper end of the side frame, a dust extraction branch pipe is provided on the dust extraction main pipe, and the dust extraction branch pipe is connected to the suction hole.

[0006] In the preferred embodiment, the lower end of the platform is provided with multiple suspension rods, the lower end of which is connected to a suspension plate. The suspension plate is provided with a rotatable lead screw. The lifting frame is provided with a guide seat, which is slidably connected to the suspension rod. The lifting frame is provided with a lead screw nut, which is connected to the lead screw.

[0007] In the preferred embodiment, the lifting frame is provided with a rotating seat, and the rotating seat is provided with a rotatable rotating shaft. The cutting blade is sleeved on one end of the rotating shaft. A synchronous belt drive mechanism is also provided. The lifting frame is provided with a cutting motor, and the cutting motor drives the rotating shaft to rotate through the synchronous belt drive mechanism.

[0008] The cutting motor, rotating base, and intermediate transmission mechanism all rise and fall together with the lifting frame, forming a cutting machine together with the boom, hanging plate, etc.

[0009] In a preferred embodiment, the rotating shaft includes a front shaft section and a rear shaft section, and a magnetic coupling is provided between the front shaft section and the rear shaft section.

[0010] In the preferred embodiment, the dust collection cover has notches on both sides, vertical slots at both ends of the notches, movable baffles that can be slidably inserted in the vertical slots, and tube slots at the lower end of the movable baffles.

[0011] In a preferred embodiment, the pressing mechanism includes multiple uprights mounted on a platform, with a top plate connected to the upper end of each upright. The top plate is equipped with a clamping cylinder and a lower pressing plate. The two ends of the lower pressing plate are slidably connected to each upright, and the clamping cylinder drives the lower pressing plate to rise and fall.

The distance between the two side limiting baffles is adjustable, and the end of the side limiting baffle away from the pressing mechanism is provided with a rolling wheel.

[0013] The beneficial effects of this utility model are as follows: the cutting position is sealed by a cover with an opening at the lower end, leaving only the pipe body channel. During cutting, the debris will impact the inner wall of the cover, slow down, and eventually be drawn away along with the cutting fumes, avoiding splashing to the outside, polluting the environment, or injuring people; the cover is equipped with replaceable movable baffles on the side to adapt to different pipe diameters; the cutting blade adopts a liftable structure, with a narrow slit through which the cutting blade passes. When the cutting blade is raised or lowered, the narrow slit will scrape off the hot melt debris adhering to the side of the cutting blade, cleaning the cutting blade; the drive motor of the cutting blade is connected to the cutting blade by a magnetic coupling coupling, which can protect the motor in case of adhesion and jamming.

[0024] The main dust extraction pipe 7 connects to the dust extraction equipment.

[0025] The plastic tube is placed on the tabletop 101 and passes under the tube pressing mechanism 4. The tube pressing mechanism 4 presses the two ends of the tube. The rotating cutting blade 906 rises, passes through the clearance groove 102 and cuts the tube body. The generated dust and smoke are blocked by the dust collection cover 5 and are sucked away through the suction hole 501.

[0026] An integrated negative pressure main pipe is used, with branch pipes extending from the top to connect to the dust collection cover 5. This does not occupy floor space and can also provide a negative pressure environment for other processes.

[0027] In the preferred embodiment, the lower end of the platform 101 is provided with a plurality of suspension rods 201, the lower end of the suspension rods 201 is connected to a suspension plate 202, the suspension plate 202 is provided with a rotatable lead screw 205, the lifting frame 9 is provided with a guide seat 901, the guide seat 901 is slidably sleeved with the suspension rods 201, and the lifting frame 9 is provided with a lead screw nut seat 206, which is sleeved with the lead screw 205.

[0028] The lifting plate 202 is equipped with a front support 204 for a lifting motor 203 and a lead screw 205. The lifting motor 203 drives the lead screw 205 to rotate.

[0029] The lifting frame 9 is a cubic structure consisting of upper and lower plates plus a vertical support plate. A guide seat 901 is set on each side of the cubic structure to enable the lifting frame 9 to move up and down stably.

[0030] In a preferred embodiment, the lifting frame 9 is provided with a rotating seat 905, and a rotatable rotating shaft 904 is provided inside the rotating seat 905.

[0032] When the cutting disc 906 cuts the plastic pipe, friction causes it to heat up. The heat accumulation from multiple cuts results in a high initial temperature for the cutting disc 906. When cutting the pipe again, the debris may melt and stick to the cutting interface, jamming the cutting disc 906 and damaging the cutting motor 902.

[0033] In a preferred embodiment, the rotating shaft 904 includes a front shaft section 907 and a rear shaft section 908, and a magnetic coupling 909 is provided between the front shaft section 907 and the rear shaft section 908.

[0035] In the preferred embodiment, the dust collection cover 5 has notches 505 on both sides, and vertical slots 502 are provided at both ends of the notches 505. A movable baffle 503 is provided in the vertical slots 502 for sliding insertion, and a tube groove 504 is provided at the lower end of the movable baffle 503.

[0036] The movable baffle 503 is easy to install and remove. The movable baffle 503 matching the pipe groove 504 can be replaced according to the size of the plastic pipe to adapt to different pipe diameters.

[0037] In a preferred embodiment, the pressing mechanism 4 includes multiple uprights 401 mounted on the platform 101. The upper end of each upright 401 is connected to a top plate 402. The top plate 402 is equipped with a pressing cylinder 404 and a lower pressing plate 403. Both ends of the lower pressing plate 403 are slidably connected to each upright 401. The pressing cylinder 404 drives the lower pressing plate 403 to rise and fall.

[0038] The pressure plate 403 can hold down the tube body to prevent it from shaking, which could cause the tube body to crack during cutting and the cutting blade to break under stress.

[0039] In the preferred embodiment, each pressing mechanism 4 is provided with two parallel and spaced side limiting baffles 3 on the side away from the dust collection cover 5. The distance between the two side limiting baffles 3 is adjustable, and the end of the side limiting baffle 3 away from the pressing mechanism 4 is provided with a rolling wheel 301.

[0040] Adjust the width between the side limit baffles 3 according to the diameter of the plastic tube to prevent the tube from tilting when compressed.
