Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a conveying structure for the polishing section of metal pipes. Background Art

[0002] Existing pipe fittings are usually classified into plastic pipe fittings, graphite pipe fittings, metal pipe fittings, etc. according to their materials. Before selling and using metal pipe fittings, a polishing machine is usually used to polish the outer wall of the metal pipe fittings. By rotating the metal pipe and using abrasives or polishing agents, dirt, oxides and defects on the surface of the pipe are removed, so that the surface of the metal pipe becomes smooth and bright, which can effectively improve the service life of the pipe fittings. Traditionally, the polishing process of metal pipe fittings is generally carried out by manual operation, with high labor intensity and low production efficiency.

[0003] For example, an automatic polishing machine for the outer wall of metal pipe fittings disclosed in Chinese Patent CN114473766A includes a placement substrate, a traction unit, a polishing unit and a chute E. A chute E is opened at the rear end of the upper end surface of the placement substrate. A traction unit is installed on the upper end surface of the placement substrate, and a polishing unit is arranged above the traction unit. The polishing unit is installed on the placement substrate. The traction unit includes a material supporting frame, material supporting wheels, a collection block, a traction wheel, a traction frame, a conveyor belt and a transmission motor. The material supporting frames are symmetrically and evenly installed on the upper end surface of the placement substrate from left to right and front to back. The material supporting wheels are installed on the material supporting frames by means of rotational connection.

[0004] In the existing automatic polishing machine, the metal pipe moves between the material supporting frame, the traction frame and the conveyor belt. The traction wheel presses the metal pipe to make it contact with the polishing wheel at the bottom. When the polishing depth of cut is large, the pipe wall of the metal pipe is prone to deformation; the metal pipe is limited by the material supporting wheels on both sides, and it is inconvenient to adjust the distance between the material supporting wheels on both sides, which cannot well meet the processing requirements of metal pipes with different diameters and has poor flexibility.

[0005] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a conveying structure for the polishing section of metal pipes with reasonable structure, stable transmission and good compatibility in view of the defects and deficiencies of the existing technology.

A driver is provided between the base and the clamping plate. The driver can drive the clamping plate to move towards or away from the material guiding groove on the bottom plate.

[0012] According to the above solution, the driver comprises a screw rod. A threaded hole is provided on the base. The screw rod is penetrated through the threaded hole and thus is threadedly connected with the base. One end of the screw rod is rotatably connected with the clamping plate. An adjusting knob is provided on the other end of the screw rod.

Through multi-point support, the pipe fitting 11 can be prevented from deforming under the grinding pressure of the polishing wheel, and the pipe fitting 11 can be prevented from running off during polishing, improving the polishing quality.

[0025] Furthermore, the mating surface of the clamping plate 3 is arranged at an angle C with the bottom plate 1, so that a plurality of support frames 32 are inclined on the mating surface of the clamping plate 3, and further the rotation center lines of a plurality of rollers 31 are arranged at an angle C with the bottom plate 1; the plurality of rollers 31 on the two clamping plates 3 form a "V"-shaped support and positioning for the pipe fitting 1, ensuring the stability of the pipe fitting 11 during polishing.
