CN-121976307-A - Spinning stretching device

Abstract

The invention relates to a spinning drawing device, which can restrain the non-uniform air flow in an incubator along the axial direction of a heating roller when a plate-shaped component is arranged in the incubator of the spinning drawing device. A plate-like member (41) is provided, and the plate-like member (41) protrudes forward from the back surface of the incubator, which is the door (27), and is disposed apart from the door (27) in a closed state. A gap between the front end of the plate-like member (41) and the door (27) in a closed state is closed by a sealing member (61). This can suppress the air flow in the axial direction (front-rear direction) of the heating roller from becoming uneven.

Description

Spinning stretching device The application is a divisional application of application number 201811553272.9, application date 2018, 12, 19 and the name of the spinning drawing device. Technical Field The present invention relates to a spinning drawing device for drawing a yarn. Background For example, patent document 1 discloses a spinning and drawing device in which a plurality of heating rolls (godet rolls) for heating a yarn are disposed in an incubator whose front surface is a door. The plurality of heating rollers are disposed in parallel with the front-rear direction in the axial direction, and a plurality of wires are wound around the outer peripheral surface thereof in a state of being aligned along the axial direction. In this spin drawing apparatus, a plurality of plate-like members are disposed so as to protrude from the back surface of the incubator toward the front door. These plate-like members function as rectifying plates or as partition plates that partition a high-temperature space from a low-temperature space in the incubator. Patent document 1 Japanese patent application laid-open No. 2015-55020 When the plate-like member disposed in the incubator protrudes forward excessively, the door comes into contact with the plate-like member when the door is closed, and the door cannot be completely closed. Accordingly, the plate-like member is disposed apart from the door in the closed state. This ensures a gap between the front end of the plate-like member and the door in the closed state, and prevents the door from coming into contact with the plate-like member. However, when there is a gap between the plate-like member and the door portion, an air flow is generated due to the air flowing in the gap. The air flow is generated at the front end part in the incubator, so that the air flow at the front part is greatly influenced, and the air flow at the rear part is relatively less influenced. Therefore, the flow of air in the incubator becomes uneven in the front-rear direction. Since the plurality of filaments wound around the heating roller are aligned in the axial direction (front-rear direction) of the heating roller, when the air flow becomes uneven in the front-rear direction, there is a possibility that the air flow varies greatly with respect to the action of each filament, and the quality of the filaments varies. Disclosure of Invention In view of the above problems, an object of the present invention is to prevent the air flow in the incubator from becoming uneven in the axial direction of the heating roller when the plate-like member is provided in the incubator. The invention provides a spinning drawing device, which is characterized by comprising an incubator, a heating roller, a plate-shaped member and a sealing member, wherein one wall surface of the incubator in a prescribed direction is a door part, the heating roller is arranged in the incubator in a mode that the axial direction is parallel to the prescribed direction, a plurality of threads are wound on the outer circumferential surface of the heating roller in a state of being arranged along the axial direction, the plate-shaped member protrudes from the other wall surface of the incubator in the prescribed direction towards one side and is separated from the door part in a closed state, and a gap between the end part of one side of the plate-shaped member and the door part in the closed state is blocked. According to the present invention, since the sealing member is provided to block the gap between the one end portion of the plate-like member and the door portion in the closed state, no air flow is generated between the plate-like member and the door portion. Thus, the air flow in the incubator in the axial direction of the heating roller can be suppressed from becoming uneven. In the present invention, it is preferable that an inlet for introducing the plurality of wires into the incubator is formed in the incubator, a 1 st rectifying plate is disposed between the inlet and the heating roller as the plate-like member, and the sealing member is provided to the 1 st rectifying plate. When there is a gap between the 1 st rectifying plate and the door portion, there is a possibility that cooler air near the introduction port flows in toward the heating roller side through the gap or warmer air around the heating roller escapes through the gap, whereby the power consumption of the heating roller increases. Therefore, by providing the 1 st rectifying plate with the sealing member, the air flow between the 1 st rectifying plate and the door can be blocked, and the increase in power consumption of the heating roller can be suppressed. In the present invention, it is preferable that a delivery port for delivering the plurality of filaments from the incubator is formed in the incubator, a2 nd rectifying plate is disposed as the plate-like member between the delivery port and the heating roller, and the sealing member is provided to
