Problems solved by technology

[0003] The existing dust-free cutting machine can only achieve a certain dust-free effect. In fact, waste dust will still be generated during work, and many tiny invisible particles will be suspended in the air, which will affect the environment and human health. If If an additional dust collection device is installed, it will not only increase the equipment cost, but also the noise and space occupied by the dust collection device will have a certain impact on transportation, assembly and production, and follow-up funds need to be invested to recycle the collected waste dust processing, which adds more cost
For some pipes of special materials, especially PVC pipes, which have the characteristics of high hardness and brittle material, the heating temperature cannot reach the cutting temperature, and burrs or cutting lines will appear on the end surface when cutting, which is not smooth and beautiful, and will cause great damage to the blade. Chipping occurs, which may damage the pipe in severe cases
Especially for the dust-free cutting machine for large-diameter PVC pipes, because of the special structure, it is more difficult to collect waste dust and debris, which is more destructive to the pipes, and it is difficult to obtain satisfactory cutting results.

Embodiment 1

[0024] Embodiment 1, the heating device 5 includes a blower and an air supply pipe 51 , the nozzle of the air supply pipe 51 is aligned with the pipe cutout, and the air supply pipe 51 is provided with a heating wire 54 . Further, the air supply pipe 51 is fixed on the cutting device 4 , and the air supply pipe 51 is also provided with a temperature sensor for controlling the heating temperature of the heating wire 54 .

[0025] After receiving the cutting signal, the half-type clamping block 31 fixed on the machine base 1 clamps the plastic pipe under the action of the cylinder 32, and the power source drives the drum 2 to rotate at a certain speed through the V-belt pulley 22. Under the action of pushing the cylinder 41, the guide block 431 drives the cutting device 4 and the limit support roller 45 to move radially towards the pipe material at the same time. At this time, the heating device 5 starts to work, and the air blower blows the air heated by the electric heating wir...

Embodiment 2

[0026] Embodiment 2, with reference to figure 2 The heating device 5 is an electric heater 52 fixed on the clamping device 3 close to the cut of the pipe. In order to achieve a good heating effect on the cut of the pipe, a partition is provided between the heating device 5 and the clamping device Thermal layer 53. When receiving the cutting signal, the heating device 5 starts to work, the electric heater 52 generates heat, and conducts the heat to the pipe clamped by the clamping device 3, and the pipe incision is heated and softened, and the cutting head 44 rotates the plastic pipe to a fixed length. cut.

[0027] Plastic pipes such as HDPE and PVC are thermoplastic polymers, which will soften when heated, and solidify and form after cooling, without changing the basic structure and performance of the material. A heating device 5 for heating and softening at the pipe cutout is provided to heat and soften the pipe After cutting, no debris and dust will be generated, the dus...

Abstract

The invention discloses a clipping device for pipes. The clipping device comprises a device base, a rotating cylinder and a clamping device; the rotating cylinder is provided with a cutting device used for cutting the pipes and the rotating cylinder is further provided with a heating device for heating and softening cut openings of the pipes; fragments and floating dust do not occur after the pipes are heated and softened, dedusting effects are better, environment and human health are not damaged, no extra dust collection equipment needs to be arranged, working noises are reduced, cost is reduced, and funding is reduced; notches are flatter, and cutting effects are better; the clipping device is particularly suitable for hard large-caliber PVC pipes, the cutting difficulty of the large-caliber PVC pipes can be greatly reduced, the cut end faces are flat, smooth, attractive and free of burrs, the pipes are not damaged, knives are not snapped, and cutting efficiency is improved; and the clipping device is simple in structure and practical.

Description

technical field [0001] The invention relates to a plastic pipe material cutting device. Background technique [0002] Plastic pipes are widely used in the fields of water supply, drainage, gas and municipal public works with the advantages of lightness, practicality, environmental protection, and non-corrosion. It solves the inconvenience of transportation, high cost, and inconvenient construction caused by the large volume and heavy quality of pipes. Due to its light weight, convenient transportation and construction, and easy interface handling, it is favored by users. Among them, PVC pipes are widely used for their strong corrosion resistance, easy bonding, low price, and hard texture. . [0003] The existing dust-free cutting machine can only achieve a certain dust-free effect. In fact, waste dust will still be generated during work, and many tiny invisible particles will be suspended in the air, which will affect the environment and human health. If If an additional d...
