Embodiment Construction
[0015] Attached below Figure 1-2 An embodiment of the present invention is described.
[0016] Spinning frame negative pressure system anti-weak twist negative pressure compensation structure, with a negative pressure channel 2 connected to the negative pressure suction source 1 and erected along the length direction of the spinning frame, such as figure 1 , figure 2 As shown, the negative pressure channel 2 and the negative pressure suction pipe 4 are all fixedly supported and installed by the bracket 6, so as to provide energy-saving, stable and unified 0.75kw negative pressure air source for each spinning frame drafting unit, the negative pressure The lower end of the pressure channel 2 evenly divides a number of vertical branched negative pressure pipes 3, and the free ends of the vertical branched negative pressure pipes 3 are connected to the negative pressure suction pipe 4 of the twisting device of the drafting unit of the spinning frame. The pressure suction pipe...

The invention provides a spinning machine negative pressure system slight twist prevention negative pressure compensation structure. The compensation structure is provided with a negative pressure channel which is communicated with a negative pressure air suction source and is erected in the machine extending direction of a spinning machine, the lower end of the negative pressure channel is evenly distributed with several vertical branch negative pressure pipelines, free ends of the vertical branch negative pressure pipelines are communicated with a negative pressure suction pipe of a twist device, the negative pressure suction pipe is arranged in the transverse direction of the machine extending direction, and is provided with several suction gaps used for twisting fiber bundles, the direction of the suction gap is the same as that of the path of the fiber bundles, the side face of the tail end of the negative pressure channel in the machine extending direction is provided with a vertical side cover plate, and a through hole which is communicated with external air and is used for compensating reduced pressure in the negative pressure channel to prevent a phenomenon of slight twist from occurring on the negative pressure suction pipe of the spinning machine twist device is formed in the middle part of the side cover plate. The spinning machine negative pressure system slight twist prevention negative pressure compensation structure can effectively compensate the pressure reduction amount caused by clog in the negative pressure channel, and has the unique advantages of being simple in structure, capable of being directly improved and achieved on existing equipment, extremely low in investment, high in economic benefit and efficient in air supply.
Description
technical field [0001] The invention belongs to the technical field of a negative pressure suction mechanism related to a ring spinning frame and a drafting unit, and in particular relates to a weak twisting negative pressure compensation structure for the negative pressure system of a spinning frame. Background technique [0002] At present, in the negative pressure suction system related to the drafting unit of the ring spinning frame (such as image 3 As shown), the drafting unit connected with the negative pressure suction source 1 to provide a constant negative pressure of 0.75kw is one of its important components. The roving or sliver can be drawn evenly or Draw down to the required number of yarns. Among them, the drafting unit must firmly absorb the sliver above the suction slit 5 of the negative pressure suction pipe 4 through the negative pressure pneumatic twisting device to achieve high-quality twisting effect. It can be seen that the negative pressure suction pi...
