Description

Technical Field

[0001] This utility model relates to the field of drawing frame technology, specifically to the air inlet opening mechanism of the drawing frame. Background Technology

[0002] Currently, the air intake cover on the TM19 drawing frame is fixed with a screw. During operation, the air intake and duct may get splattered, easily causing blockage and making it difficult to observe the splattering. Furthermore, blockage requires removing the screw to remove the cover. Additionally, the negative pressure generated at the air intake can suck the cover away, making removal even more difficult. Therefore, we have designed an air intake cover opening mechanism.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a drawing frame air inlet opening mechanism, including a drawing frame body 1 and a cover plate 2 disposed at the air inlet of the drawing frame body 1. The drawing frame body 1 is provided with a placement groove 3 for placing the cover plate 2. The cover plate 2 is rotatably disposed on the inner end of the placement groove 3. The mechanism also includes:

[0033] Pressure relief port 4 is located at the front end of the main body 1 of the drawing frame and communicates with the internal space of the air intake.

[0034] The blocking unit 5 is disposed at the pressure relief port 4 and is used to block and open the pressure relief port 4;

[0035] The opening and closing unit 6 is disposed between the outer end of the cover plate 2 and the placement groove 3, and the outer end of the cover plate 2 and the placement groove 3 are fixedly engaged.

[0036] The blocking unit 5 includes:

[0037] A rubber plug 51 is provided at the pressure relief port 4;

[0038] The sliding column 52 has one end connected to the inner end of the rubber plug 51, and the other end passes through the pressure relief port to the air intake port and is provided with a limiting piece 54.

[0039] The return spring 53 is sleeved on the sliding column 52, with one end abutting against the inner wall of the air intake space and the other end abutting against the limiting piece 54.

[0040] In addition, the opening and closing unit 6 includes:

[0041] A hook-shaped block 61 is disposed on the outer end of the placement groove 3 and is slidably disposed on the placement groove 3;

[0042] A locking block 62 is provided on the outer end of the cover plate 2, and the locking block 62 is provided with a hook groove 63 for use with the hook block 61;

[0043] A connector 64 is disposed between the limiting piece 54 and the hook block 61 for connecting the limiting piece 54 and the hook block 61.

[0044] Meanwhile, the connector 64 is configured as a connecting plate, with one end of the connecting plate connected to the limiting piece 54 and the other end connected to the hook-shaped block 61.

[0045] An auxiliary component 7 is provided between the cover plate 2 and the placement groove 3 to assist in opening the cover plate 2;

[0046] The auxiliary component 7 includes:

[0047] Two sets of storage slots 71 are symmetrically arranged on both sides of the placement slot 3;

[0048] Two sets of spring telescopic rods 72, one end of which is rotatably mounted on the outer end of the storage slot 71, and the other end of which is rotatably mounted with a collar 73;

[0049] The slide rod 74 is fixedly mounted on the cover plate 2, and the collar 73 is slidably mounted on the slide rod 74.

[0050] In addition, a pull ball 511 is provided on the outer end of the rubber stopper 51 to facilitate pulling the rubber stopper 51 outward.

[0051] Finally, the cover plate 2 is made of a transparent material.

[0052] In practical implementation, the transparent material of the cover plate 2 can be transparent glass or plastic. This allows observation of the fraying inside the air intake through the cover plate 2. When there is a lot of fraying, the rubber plug 51 can be pulled outward by the pull ball 511 to open the pressure relief port 4, thereby balancing the pressure inside the air intake and outside the main body 1 of the drawing frame, preventing the cover plate 2 from being sucked in by the negative pressure inside the air intake. When the rubber plug 51 is pulled out, the hook block 61 can be moved outward by a distance through the connecting plate, releasing the hook groove 63 on the locking block 62 from locking. The effect is that the cover plate 2 can be opened under the action of the spring telescopic rod 72, and the rubber plug 51 is reset under the manual pressing of the return spring 53. In addition, after the cover plate 2 is opened, the pull ring in the air intake can be cleaned to prevent blockage of the air intake. After cleaning, the cover plate 2 can be pressed down again, and the hook groove 63 on the locking block 62 will be locked into the hook block 61. The spring telescopic rod 72 will have a certain tilt angle after entering the storage groove 71, which makes it easier to open the cover plate 2 after the locking is released.
