Description

Technical Field

[0001] The utility model relates to the technical field of shielding doors, in particular to a water-blocking door structure used for a special fiber washing machine. Background Art

[0002] Special fiber is a fiber structure manufactured by related fiber manufacturing enterprises. It has special physical and chemical structure, performance and use, or chemical fiber with special functions (corrosion-resistant fiber, high temperature-resistant fiber, flame-resistant fiber, high-strength and high modulus fiber, functional fiber and elastomeric fiber, etc.). Most of them are used in industry, national defense, medical, environmental protection and cutting-edge science. In the production process of some special fibers, they need to enter the washing machine (washing area) for washing. The washing machine includes an upper guide roller and a lower guide roller arranged in an alternating manner. The fiber passes through the upper surface of the upper guide roller and the lower surface of the lower guide roller. During the process, it is washed and rinsed by pure water to remove residual solvent impurities on the fiber surface. At present, the length of the washing machine is determined by the corresponding fiber production needs. The water retaining gate of the washing machine has three structures, namely, overall pull-up type, horizontal push-down type, and film pull-down type.

[0003] The overall pull-up water retaining door has a high requirement on the floor height of the factory building, which is 1.8 to 2.0 times the height of the water washing machine. The large space increases the costs of air conditioning, ventilation and dust-free.

[0004] For horizontal push-type water retaining doors, there is no need for too much vertical height in the vertical direction, and the door can be opened without too much force for horizontal stretching. However, for a washing machine, the vertically arranged sliding door intersects with the door in many places along the fiber path, which means that when the fiber is pulled, the door structure will hinder the manual pulling process of personnel. To avoid this obstruction, each door is usually not too large, and the obstruction is not obvious when there are fewer doors. When the washing machine is longer and there are more doors, the obstruction to the pulling will continue to increase with the linkage between the doors. At the same time, horizontal sliding doors are generally staggered to make room for the pulling operation. When the transparent door is splashed by internal washing water and affects observation, the staggered door structure will cause trouble for wiping and cleaning the internal water due to the overlap between the doors when it is open.

[0005] The film pull-down water retaining door is too thin and easy to deform. The edge is smaller than the scroll structure, which will form a gap at the connection position. Therefore, a corresponding splash-proof structure should be arranged. At the same time, it is easy to be affected by heat deformation when using hot water or other special cleaning conditions.

[0006] Therefore, it is necessary to further study and improve the existing water retaining door used in the special fiber washing machine to overcome the above problems. Utility Model Content

[0007] In view of this, the utility model proposes a water retaining door structure for a special fiber washing machine, which mainly divides the area where the door is installed in the special fiber washing machine into an upper area and a lower area. The lower end of the upper area is opened to the lower edge of the upper wire guide roller, and an up and down lifting water retaining door is arranged in the upper area, and a winding and folding water retaining door is arranged in the lower area, thereby reducing the height of the water retaining door in the upper area and lowering the requirement for the floor height of the factory building.

[0018] Preferably, when the lifting water retaining door body is raised by external force, the counterweight block runs vertically downward or obliquely downward. The counterweight block runs vertically downward, that is, no baffle is set on the metal bracket in the direction of the counterweight block's movement; the counterweight block runs obliquely downward, that is, an oblique downward block is provided on the metal bracket.

[0019] Preferably, the length of the horizontal guide rod is smaller than the width between the two hollow columns, the upper end of the hollow column is provided with a groove for inserting into the middle part of the lower edge of the lifting water retaining door body, the middle part of the lower edge of the lifting water retaining door body is provided with a first locking portion, and the groove is provided with a first push lock for connecting with the first locking portion.

[0020] Preferably, the upper edge of the retractable and foldable water retaining door body is also provided with a one-way bending chain, and the one-way bending chain on the upper edge of the retractable and foldable water retaining door body passes through the guide rail groove below the horizontal guide rod.

[0024] 1. The design adopts a structure of upper and lower doors, with the upper area being a lifting water retaining door and the lower area being a retractable and folding water retaining door. Compared with the overall design of lifting doors, this scheme greatly reduces the requirements for the floor height space of the plant where the washing machine is installed.

When the lifting water retaining door body is pulled down to close, the counterweight block always has a force to pull the lifting water retaining door body upward, and the first lock of the lifting water retaining door body is hooked with the lock tongue of the first push lock to achieve limit locking. At this time, the weight of the lifting water retaining door body does not need to be borne by the horizontal guide rod below, and will not affect the retractable folding water retaining door below.

[0026] 3. The lower area is designed with a retractable folding water retaining door. Through the coiling spring reel and the one-way bending chain, the retractable folding water retaining door body is folded in one direction. When straightened, it is a straight plane.
