Description

Technical Field

[0001] The utility model belongs to the technical field of pipe processing, and in particular relates to a pipe wall cleaning device for PVC pipe production. Background Art

[0002] It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. PVC pipe is a product under its material. Only a part of the produced PVC pipe is used for pipeline construction, and the other part is kept as inventory. After a period of time, the inner wall of the stored PVC pipe will be stained with a little dust. At present, the cleaning device cooperates with the rotating mechanism, the driving mechanism and the spray mechanism to ensure that the inner wall of the plastic pipe will not have a low cleaning rate and unclean cleaning during the cleaning process. However, only one PVC pipe can be cleaned, and the cleaning speed of the pipe fittings is slow, which will affect the production progress of the PVC pipe.

[0003] To this end, a PVC pipe inner wall processing and cleaning device with a bulletin number of "CN214235418U" belongs to the technical field of PVC pipe production equipment, including a workbench, a screw slide, an inner wall cleaning mechanism, a lifting mechanism and a workpiece limiting mechanism. The top of the workbench is provided with a plurality of V-shaped grooves; the inner wall cleaning mechanism includes a support frame, a drive motor and a plurality of support seats, each support seat is provided with a brush roller rotatably connected thereto, and the main shaft of the drive motor is connected to the end of the brush roller located on the far right by a coupling. The utility model can make all the brush rollers rotate synchronously through the inner wall cleaning mechanism, so that multiple brush rollers can clean the inner walls of multiple PVC pipes respectively, thereby improving the cleaning efficiency of the inner wall of the PVC pipe by the device, and the material stripping strip can be moved horizontally through the operation of the pushing cylinder, so that the material stripping strip pushes the PVC pipe to move to the left, and pushes the PVC pipe to the corresponding support cross bar, so as to complete the automatic unloading of the PVC pipe.

[0004] However, for the above-mentioned PVC pipe inner wall processing and cleaning equipment, although the push cylinder can make the stripping bar move horizontally, so that the stripping bar pushes the PVC pipe to the left, and pushes the PVC pipe to the corresponding supporting cross bar to complete the unloading of the PVC pipe, which is convenient for the staff to collect materials in a centralized manner, there are still the following obvious defects during use: However, this unloading method still requires the staff to remove the pipe fittings on the supporting cross bar one by one, but when the pipe fittings need to be processed, the staff are required to place the pipe fittings on the conveyor line for transportation, which not only increases the manual unloading link with slow production and processing speed of pipe fittings, but also affects the production progress of pipe fittings.

This conveying method is conducive to cleaning the inner wall dust and vacuum adsorption collection of the dust after positioning each pipe in turn during transportation. At the same time, the cleaned pipes do not need to increase the manual unloading link, and only need to start the positioning conveyor belt again to convey the pipes to the corresponding pipe processing link at the end of the pipe conveyor line or to the external material receiving equipment for collection, so that the production of pipes has a certain inertia and improves the production and processing progress of pipes.

The rotation of the servo motor causes the brush rod to rotate inside the pipe fitting, so that the dust on the pipe wall can be cleaned. Since the dust will flow to the outside of both ends, the vacuum extraction pump is used to make the rubber air pipe have vacuum suction to absorb the dust floating on the inside of the pipe wall and collect it in the collecting box, thereby avoiding the problem of the cleaned dust flowing out of the pipe fitting and polluting the surrounding environment.
