Problems solved by technology
This type of drive does not need to replace the front bottom roller, and the draft ratio of the accumulation area can be changed according to the process needs, but because the additional transmission shaft (fifth roller) needs to occupy the originally compact downstream space of the drafting part, it will affect the operation and Maintenance work, while the transmission shaft (fifth roller) and its bearings and transmission gears also increase the investment cost of the plant renovation

Embodiment Construction
[0022] A four-roller negative pressure compact spinning device, including the upper and lower rollers before drafting, negative pressure tubes, grid rings, twist-stop top and bottom rollers and their pressurizing mechanism, wherein the twist-stop bottom rollers are composed of the front or the front and rear parts direct drive.
[0023] The drive of the headstock or rear part to the bottom twist roller is preferably driven by the front bottom roller head section or tail section of the drafting through the front bottom roller head gear, the bridge gear and the twist bottom roller head gear transmission. It can also be driven by the synchronous pulley of the front bottom roller, the synchronous belt and the synchronous pulley of the anti-twisting bottom roller.
[0024] The front or rear part of the drive to the bottom twist roller can also be driven synchronously by an independent motor and the drafting part. It is driven by synchronous control such as stepping motor or servo ...

Abstract
The invention provides a four-roller negative pressure gathering spinning device which comprises a front upper traction roller, a front lower traction roller, a negative pressure pipe, a grid ring, an upper twisting-resistant roller, a lower twisting-resistant roller and a pressurized mechanism. The four-roller negative pressure gathering spinning device is characterized in that the lower twisting-resistant roller is directly driven by a turning head or part of the turning head and a turning tail, and the two ends of each segment of the lower twisting-resistant roller in the middle of each roller seat are provided with drive coupling structures capable of being detached out of the adjacent lower twisting-resistant roller. According to technical scheme, the four-roller negative pressure gathering spinning device has the advantages of being convenient to reform, less in additional element, convenient and fast to maintain and replace, reliable to drive, low in investment and operation cost and the like.
Description
technical field [0001] The invention relates to a compact spinning device on a spinning machine, in particular to a negative pressure airflow type four-roller compact spinning device. Background technique [0002] In the prior art, the negative pressure airflow type four-roller compact spinning device attached to the ring spinning frame has a main structure including upper and lower rollers before drafting, negative pressure tubes, mesh rings, twist blocking upper and lower rollers (fourth rollers) and Its pressurizing mechanism, in which the driving of the twist-stop top and bottom rollers and grid rings, generally has the following forms: [0003] Firstly, there are coaxial transmission gears on the front bottom roller and bottom twist roller of each section, the gear on the front bottom roller transmits the gear on the bottom twist roller through the bridge gear, and the bottom twist roller rubs through the twist jaw Drive the twist-stop top roller to realize the drive o...
