Problems solved by technology

However, in actual production, the reserved installation margin often does not match the actual expansion of the box, resulting in misalignment of the metering pump drive, easy damage to the metering pump, and affecting production
Since the metering pump is located in the narrow space of the spinning box and its surface temperature is high, it is difficult to measure its concentricity with the transmission center. Usually, it is roughly adjusted by visual inspection. If the concentricity is poor, the metering pump fragile

Embodiment Construction

[0011] Below by non-limiting embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0012] As shown in the accompanying drawings, it is a schematic diagram of the present invention in practical application. The present invention includes a sleeve 5 with a central hole in the axial direction and a correction rod 4 that is passed through the central hole of the sleeve 5 and can slide axially. One end of the sleeve 5 has a coupling plate. The matching gap between the rod 4 and the center hole of the sleeve is preferably 0.03mm~0.04mm. The head end of the correction rod 4 has a correction head 3, which matches the shaft hole of the metering pump coupling 2. The correction rod The tail end of 4 is tapered to facilitate assembly. There is also a locking screw 6 on the sleeve 5, so that the correction rod 4 can be locked.

[0013] When the present invention is applied in practice, the connecting disk of the sleeve 5 is connected ...

Abstract

The invention discloses a correcting device of a transmission center of a metering pump of a spinning machine, which belongs to the technical field of chemical fiber spinning devices. The correcting device comprises a sleeve (5) and a correcting rod (4), wherein the sleeve (5) is provided with an axial center hole; the correcting rod (4) passes through the center hole of the sleeve (5) and can slide along the axial direction; and a jointing plate matched with a disc type coupling is arranged on one end of the sleeve (5), and a correcting head (3) matched with an axial hole of the coupling of the metering pump is arranged on the head end of the correcting rod (4). The correcting device is simple in structure, accurate in correction, safe and convenient in operation, and the invalidation problem of the metering pump caused by the decentraction between the metering pump and the transmission center can be solved.

Description

technical field [0001] The invention relates to a transmission center correction device for a spinning metering pump, which belongs to the technical field of chemical fiber spinning equipment. Background technique [0002] The spinning machine is the key equipment in the production of chemical fibers. The polyester melt under high temperature and high pressure is measured by the gear metering pump installed in the spinning box, and then sprayed out by the spinning components to form fiber precursors. . The metering pump is driven to rotate by a reducer on an external steel platform through a drive rod. Since the temperature in the spinning box is generally about 300 degrees Celsius during normal production, in order to adapt to the thermal expansion of the box, one end of the supports at both ends of the spinning box is fixed and the other is movable, so as to facilitate spinning. The wire box can be stretched freely. Usually, when initially installing the metering pump t...
