Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a winding air shaft assembly. Background Technology

[0002] In the winding operation of slitting and rewinding equipment, traditional winding structures often suffer from cumbersome operation and low efficiency. Existing structures rely heavily on frequent manual adjustments of component positions to install paper tubes and unload finished products. This not only consumes a large amount of manpower but also easily leads to deviations when aligning the air shaft and fixing the winding components, resulting in insufficient stability of the air shaft and affecting winding quality. Furthermore, traditional structures lack automated collaborative control; after winding, the fixed components must be manually disassembled step by step to remove the finished product, a time-consuming process that is difficult to adapt to the demands of high-efficiency production. In addition, some structural components have poor coordination, and during winding, loose components can easily cause material misalignment, further reducing production efficiency and product qualification rate, failing to meet the industry's demand for a fast, stable, and low-manual-reliance winding process. Utility Model Content

[0005] Furthermore, a spherical bearing mandrel is connected to the output end of the slide cylinder, and the spherical bearing mandrel passes through the slide fixing plate and is locked with a nut.

[0006] Furthermore, a pneumatic high-speed rotary joint is connected to the power input end of the winding air shaft.

[0007] Furthermore, the power input end of the winding air shaft is rotatably mounted in a bearing housing using several deep groove ball bearings, and the bearing housing is mounted on the frame of the equipment using several screws.

[0008] Furthermore, a round nut is provided on the outer side of the deep groove ball bearing adjacent to the winding synchronous belt pulley. The round nut is installed on the power input end of the winding air shaft, and a round nut retaining washer is sandwiched between the round nut and the deep groove ball bearing.

[0009] Furthermore, the outer wall of the winding air shaft ejector pin is provided with a strip-shaped guide groove, and an internal hexagonal head screw is installed in the strip-shaped guide groove and locked and positioned by a hexagonal nut.

[0010] Furthermore, a take-up air shaft guide sleeve is installed on the end of the take-up air shaft ejector pin that is away from the output end of the ejector cylinder.

[0011] Furthermore, the linear slide rail is mounted on a slide rail fixing plate, which is mounted on the frame of the equipment, and both the upper and lower ends of the slide rail fixing plate are equipped with slider baffles.

The slide rail fixing plate 9 is mounted on the frame of the equipment, and both the upper and lower ends of the slide rail fixing plate 9 are equipped with slider baffles 21; the top of the slide base fixing plate 2 is equipped with a winding air shaft ejector pin slide 7, and the tail end of the winding air shaft ejector pin slide 7 is equipped with an ejector pin cylinder 4. The output end of the ejector pin cylinder 4 is connected to the winding air shaft ejector pin 18. The winding air shaft ejector pin 18 is detachably connected to the movable end shaft of the winding air shaft 6, and the movable end shaft abuts against the self-aligning bearing 19 at the end of the winding air shaft ejector pin 18; The outer wall of the take-up air shaft ejector pin 18 is provided with a strip-shaped guide groove. A hexagonal head screw 16 is installed in the strip-shaped guide groove and locked and positioned by a hexagonal nut 17. A take-up air shaft ejector pin guide sleeve 20 is installed on the end of the take-up air shaft ejector pin 18 away from the output end of the ejector cylinder 4. The power input end of the take-up air shaft 6 is connected to the take-up synchronous belt pulley 5. The power input end of the take-up air shaft 6 is rotatably mounted in a bearing seat 15 by several deep groove ball bearings 11. The bearing seat 15 is mounted on the frame of the equipment by several screws. A round nut 14 is provided on the outer side of the deep groove ball bearing 11 adjacent to the take-up synchronous belt pulley 5.

[0023] When using this utility model, the ejector cylinder 4 retracts, causing the take-up air shaft ejector pin 18 to disengage from the take-up air shaft 6. The slide cylinder 1 retracts, causing the slide fixing plate 2 and its components to descend. The operator manually installs a paper tube of appropriate width on the take-up air shaft according to product requirements. The slide cylinder 1 extends, causing the slide fixing plate 2 and its components to rise, thereby aligning the take-up air shaft ejector pin 18 with the take-up air shaft 6.
