Abstract
The utility model discloses an air returning door structure for a dedusting device of a flat knitting machine. The air returning door structure is arranged between an air suction pipeline and a dust storage chamber and comprises an air returning door, wherein the air returning door is arranged between the air suction pipeline and the dust storage chamber through a movable structure. The air returning door structure for the dedusting device of the flat knitting machine has the advantages that the structure is simple and flexible, clews and flosses can be prevented from returning to an air returning pipeline and an air returning port, and the cleaning efficiency is increased.
Description
Technical field
The utility model relates to the return air door in a kind of straight-bar machines dust arrester.
Background technology
Straight-bar machines is after long-time running, because the fabric of straight-bar machines inside, yarn etc. the end of a thread, tiny line segment suede thing also has airborne foreign material, all can slowly put aside accumulation and form a ball of string, add greasy dirts a lot of on the straight-bar machines, so that a ball of string has certain gravity, stick on the straight-bar machines, be difficult to clean, bring impact for whole equipment, and such impact As time goes on can be more and more serious.
General straight-bar machines just is equipped with very simple air intake device, a ball of string is adsorbed focus on, but efficient is low, sticks on the blower fan, processes to be not easy very much.
Summary of the invention
The purpose of this utility model is to provide the return air door in a kind of straight-bar machines dust arrester, simple in structurely flexibly prevents that the ball of string wadding head from getting back to return air duct and return air inlet, improves cleaning efficiency.
To achieve these goals, the technical solution of the utility model is as follows:
Return air door in the straight-bar machines dust arrester is arranged between air-suction duct and the dust-storage chamber, it is characterized in that: comprise the return air door, described return air door is arranged between air-suction duct and the dust-storage chamber by bascule.
Further, be provided with sealing ring in the edge of return air door.
Further, the thickness of described sealing ring is 2-4mm.
The setting of this structure can stop wind to get back to air-suction duct, so that the wind-force that blower fan produces is stayed in the dust-storage chamber, greatly improves dust discharge efficient, and ball of string wadding head and so on can not get back to the inlet scoop, do not affect whole use.
When blower fan generation wind-force, the return air door is opened automatically, and a ball of string is absorbed in the dust-storage chamber.
When the blower fan backward rotation, the return air door is under the effect of wind-force, and the return air door is closed, and blower fan reduces manually-operated with all cleanings of the wadding of the ball of string in dust-storage chamber head and so on, improves cleaning efficiency.
Further, described bascule is one the rotating shaft of return air door top middle portion to be set.
The beneficial effects of the utility model: the utility model is simple in structure flexibly, prevents that the ball of string wadding head from getting back to return air duct and return air inlet, improves cleaning efficiency.
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
Description of drawings
Fig. 1 is structural representation of the present utility model;
The specific embodiment
As shown in Figure 1, the utility model relates to the return air door in a kind of straight-bar machines dust arrester, be arranged between air-suction duct 1 and the dust-storage chamber 2, it is characterized in that: comprise return air door 3, described return air door 3 is arranged between air-suction duct 1 and the dust-storage chamber 2 by bascule.
Further arrange, be provided with sealing ring 4 in the edge of return air door 3.
Further arrange, the thickness of described sealing ring 4 is 2-4mm.
Further arrange, described bascule is one the rotating shaft 5 of return air door 3 top middle portion to be set.
As from the foregoing, the utility model is simple in structure flexibly, prevents that the ball of string wadding head from getting back to return air duct and return air inlet, improves cleaning efficiency.
More than be that the technical scheme that the utility model embodiment provides is described in detail, having used specific case herein sets forth principle and the embodiment of the utility model embodiment, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all can change to some extent on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
Claims (4)
1. the return air door in the straight-bar machines dust arrester is arranged between air-suction duct and the dust-storage chamber, it is characterized in that: comprise the return air door, described return air door is arranged between air-suction duct and the dust-storage chamber by bascule.
2. the return air door in the described straight-bar machines dust arrester according to claim 1, it is characterized in that: the edge at the return air door is provided with sealing ring.
