Description

Technical Field

[0001] The present invention relates to the technical field of cable pipe processing, and specifically to a PVC cable pipe processing technology and its chip-free cutting equipment. Background Technique

[0002] During the cable laying process, to prevent the cable from being damaged by external forces, a cable protection pipe needs to be set outside the cable to protect the cable. To make the length of the cable protection pipe match the cable, the length of the cable protection pipe needs to be cut.

[0003] Existing cable pipes are generally cut on-site during laying, resulting in inaccurate length positioning during the cutting process, and generally no plastic chip collection mechanism is set during the processing. As a result, plastic chips are likely to be scattered in the soil at the embedding location, making subsequent collection and processing difficult and easily causing environmental pollution. Therefore, we propose a PVC cable pipe processing technology and its chip-free cutting equipment to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a PVC cable pipe processing technology and its chip-free cutting equipment to solve the problems raised in the above background technique.

[0005] The present invention provides a PVC cable pipe processing technology, including,

[0006] Step 1: Measurement step, measuring the diameter, length, ground clearance height and specific opening position of the pipe to be cut;

[0008] Step 3: Be able to pre-fix the pipe to be cut to prevent the pipe from falling after cutting, and at the same time be able to clean the impurities and the like accumulated on the surface of the pipe during the transmission process;

[0009] Step 4: After the installation and positioning are completed, cut the pipe, and at the same time, the external air pressure equipment is used as a drive to cooperate with the cutting equipment to recycle the generated debris.

[0010] The present invention provides a PVC cable pipe chip-free cutting equipment, including,

A rectangular groove is opened on the side wall of the telescopic plate, and a transmission belt is movably arranged inside the rectangular groove. The output end of the servo motor abuts against the inner wall of the transmission belt. As the servo motor starts to operate, the transmission belt starts to rotate, which can make the plastic pipe limited inside the transmission mechanism move, so as to adjust the length and cut according to requirements.

[0017] Preferably, a plurality of circular grooves are opened on the side wall of the telescopic plate, and the inner diameter of the circular groove is equal to the inner diameter of the positioning hole.

During the cutting process of the cable pipeline, as it rotates by itself, its cut can abut against the arc-shaped dust suction plate, so as to separate excess debris, etc., and avoid the situation of residue.

[0021] Preferably, a rectangular frame is inserted into the arc-shaped cover plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1.

[0028] 4. When the cable pipeline is being cut, as it rotates itself, its cut can abut against the arc-shaped dust suction plate, separating excess debris and avoiding residue. At the same time, the grinding shaft can deburr the notch, facilitating subsequent assembly. And as the pipeline and the support shaft are pressed against each other, the arc-shaped dust suction plate can be extruded and pushed, reducing the residue of burrs.

[0029] 5. During the transmission of the cable pipeline, it can be mutually extruded with the rubber tube, cleaning the sludge and impurities attached to the surface of the cable pipe. And as the surface of the conveyor belt and the buffer ball are mutually extruded, the collecting ring can be driven to swing, strengthening the cleaning effect on the sludge and thus reducing the residue situation.
