An automatic coiling device of a protective tube packaging machine for flexible shafts

Abstract

The invention discloses an automatic coiling device for a flexible shaft protection pipe package molding machine. The automatic coiling device comprises a frame body, a drawing mechanism, a mounting rack, a guide pipe, a first guide frame, a second guide frame, an adjusting rod, a bearing, a bent pipe, a plurality of guide wheels, a first rotating wheel, a charging barrel and a bearing pedestal. The drawing mechanism and the mounting rack are arranged on the frame body. The guide pipe and the guide wheels are arranged in the mounting rack. The guide wheels are arranged behind the guide pipe in parallel so as to guide a protection pipe to change from previous horizontal movement to downward movement. The output end of the mounting rack is provided with the adjusting rod. The first guide frame and the second guide frame are arranged on the adjusting rod. The lower end of the adjusting rod is provided with a bearing sleeve. The input end of the bent pipe is inserted in an inner ring of the bearing. The charging barrel is arranged under the output end of the mounting rack. Compared with the prior art, the automatic coiling device can save manpower, improve working efficiency and reduce production cost, is good in coiling effect and can also reduce the service power of a motor, avoid surface abrasion of the protection pipe and guarantee product appearance quality.

Description

【Technical Field】 [0001] The invention relates to the technical field of a protective tube coating machine for flexible shafts, in particular to the technical field of an automatic coiling device of a protective tube coating machine for flexible shafts. 【Background technique】 [0002] The flexible shaft is mainly used to connect the axes of two transmission parts that are not on the same straight line, or when working, they require space transmission for relative movement. It can bend around various obstacles and transmit rotary motion in a long distance. It is suitable for occasions subject to continuous vibration to alleviate impact, and also suitable for occasions with high speed and small torque. [0003] Flexible shaft usually consists of four main parts: mandrel, protective tube, mandrel joint and protective tube joint. Protective tube production: First, the metal belt is continuously wound into a sleeve at a helix angle, and the surface is overmolded by a plastic extruder....

AI Technical Summary

Problems solved by technology

In the prior art, the plastic-coated metal sleeve is manually coiled in the barrel, and backup personnel are required to exchange it during the production process, which wastes manpower, reduces production efficiency, increases production costs, and reduces the coiling effect. Difference

[0004] At present, the protective tube overmolding machine for flexible shafts in China is composed of an inlet tube guide, a plastic extruder, a water cooling device, a traction mechanism, and an outlet tube guide. The completed protective tube is guided in the direction, and then the protective tube is manually coiled in the barrel. When the protective tube is guided through the guide bend, it rubs against the inner wall of the guide bend, which increases the resistance and thus increases the power of the motor. Wear the surface of the protective tube, affecting the appearance quality of the product
