[0002] In the textile industry, transmission tracks are erected between workshops, and transmission chains are arranged on the tracks to convey materials from one process workshop to the next process workshop, ensuring the continuity of the production process.

[0003] When the transmission chain conveys materials to the tail yarn workshop for processing, at this time, the chain will carry the pin rod or enter the automatic cleaner in an empty load state for cleaning. After cleaning, the chain moves to the roving workshop to wait for the next work. However, when the chain is being cleaned, the air gun in the automatic cleaner will blow impurities such as fiber fragments and dust attached to part of the chain and the pin rod into the roving workshop, thus affecting the processing quality of the fiber sliver in the roving workshop. Therefore, this application particularly proposes a dust prevention device that can reduce the amount of dust blown out by the automatic cleaner while not affecting the cleaning of the transmission chain.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0022] See Figures 1-3 。

[0023] The present utility model discloses a dust-proof device, including:

[0024] A dust-proof cover 1, which is arranged in the wall groove between the automatic cleaner and the coarse sand workshop. An opening 11 is provided on the dust-proof cover 1, and the position of the opening 11 corresponds to the entrance position of the automatic cleaner. A space for the transmission track to pass through is left at the top of the opening 11;

[0025] An opening and closing component 2, including two dust-proof doors 21 rotatably arranged at the opening 11. The two dust-proof doors 21 are arranged opposite to each other, and a torsion spring (not shown in the figure) is provided at the rotating joint between each dust-proof door 21 and the dust-proof cover 1. The torsion spring is used to drive the corresponding dust-proof door 21 to rotate relatively to close the opening 11. When the transmission chain carries the pin rod and moves into the automatic cleaner, the pin rod contacts each dust-proof door 21 and drives the dust-proof door 21 to rotate, opening the opening 11.

[0026] In specific implementation, when the no-load transmission chain enters the automatic cleaner through the transmission track, each torsion spring provides a torsion force towards the center of the dust-proof cover 1 for the corresponding dust-proof door 21. At this time, the dust-proof doors 21 are in contact with each other, the opening 11 is closed, and the airflow carrying impurities blown out during the operation of the automatic cleaner is blocked by the dust-proof cover 1 and the dust-proof doors 21, so that the dust is concentrated in the wall groove. After cleaning, the transmission chain leaves the dust-proof cover 1 through the top of the opening 11. When the transmission chain carries the pin rod into the automatic cleaner, the pin rod contacts the dust-proof doors 21. As the pin rod continues to move, the pin rod drives the dust-proof doors 21 to rotate. At this time, the dust-proof doors 21 move away from each other, the opening 11 is opened, and there is a space for the pin rod to pass between the two dust-proof doors 21, and each torsion spring is compressed. The pin rod enters the dust-proof cover 1 through the opening 11. When the pin rod no longer contacts the dust-proof doors 21, each torsion spring loses restraint and drives the corresponding dust-proof door 21 to rotate towards the center of the dust-proof cover 1 until the two dust-proof doors 21 are in contact with each other and the opening 11 is closed.

[0027] In the utility model, when the transmission chain is no-load, the dust-proof cover 1 and the opening and closing component 2 cooperate with each other to reduce the dust and impurities blown out from the outlet of the automatic cleaner to the workshop. When the transmission chain carries the pin rod, through the cooperation between the pin rod and the dust-proof door 21, when the pin rod passes through the dust-proof cover 1, there is enough space for the pin rod to pass between the two dust-proof doors 21. When the pin rod leaves, each dust-proof door 21 closes the opening 11 and blocks the dust and impurities, so as to achieve the function of reducing the amount of dust blown out by the automatic cleaner.

[0028] In an embodiment, a first groove 12 is formed on the inner wall of the bottom end of the dust-proof cover 1;

[0029] A storage component 3 is arranged below the dust-proof cover 1. The storage component 3 includes a storage box 31 arranged at the bottom end of the dust-proof cover 1. A limiting plate 32 is arranged on the side of the storage box 31 away from the wall. The limiting plate 32 is rotatably connected to the bottom end of the storage box 31. A torsion spring (not shown in the figure) is arranged at the rotation connection of the limiting plate 32 and the storage box 31. The torsion spring is used to apply an upward rotation torsion force to the limiting plate 32. A first limiting strip 321 corresponding to the first groove 12 is arranged on the surface of the limiting plate 32 in contact with the dust-proof cover 1. When the first limiting strip 321 is inserted into the first groove 12, the first limiting strip 321 is used to connect the dust-proof cover 1 and the storage box 31.

[0030] With this design, when it is necessary to collect the dust blown out by the automatic cleaner, the staff rotates the limit plate 32 towards the wall and inserts the top of the storage box 31 into the bottom of the dust cover 1. At this time, the torsion spring is compressed. When the storage box 31 is placed in a suitable position, the limit plate 32 is released, the torsion spring loses its constraint and drives the limit plate 32 to rotate upward so that the first limit bar 321 is inserted into the first groove 12. At this time, the side of the storage box 31 away from the first limit bar 321 is close to the wall, and the dust and impurities blown out by the automatic cleaner are blocked by the dust cover 1 and the dust door 21 and fall into the storage box 31 under the influence of gravity. When the storage box 31 needs to be removed, the limit plate 32 is rotated downward to disengage the first limit bar 321 from the first groove 12, and the storage box 31 can be pulled out downward.

[0031] In one embodiment, a partition component 4 is further provided under the dust cover 1, and the partition component 4 includes a transmission rod 41 rotatably arranged on the inner wall of the dust cover 1, and the transmission rod 41 is arranged along the length direction of the storage box 31 and one end thereof passes through the dust cover 1. A partition plate 42 is also provided on the transmission rod 41. When the partition plate 42 is close to the dust cover 1, the partition plate 42 is magnetically matched with the dust cover 1, and the partition plate 42 is used to connect or isolate the space between the storage box 31 and the dust cover 1.

[0032] With this design, when it is necessary to collect the dust blown out by the automatic cleaner, the transmission rod 41 is rotated and the partition plate 42 is driven to rotate upward until the partition plate 42 is in contact with the inner wall of the dust cover 1. At this time, the partition plate 42 and the dust cover 1 attract each other, and the inner cavity of the dust cover 1 is connected with the inner cavity of the storage box 31. The dust impurities blown out by the automatic cleaner fall into the storage box 31. When it is necessary to clean the dust impurities, the transmission rod 41 is rotated and the partition plate 42 is driven to rotate downward to separate the partition plate 42 from the dust cover 1, and the partition plate 42 is away from the dust cover 1 and the side of the rotating joint of the partition plate 42 is placed on the wall. At this time, the partition plate 42 closes the bottom end of the dust cover 1, and the staff removes the storage box 31 for cleaning. During the cleaning process, the partition plate 42 is used to prevent dust impurities in the dust cover 1 from entering the workshop.

[0033] In one embodiment, a guide plate 5 is provided at the wall groove. The guide plate 5 is arranged below the outlet of the automatic cleaner and is arranged in a triangular shape. The guide plate 5 is used to guide the airflow and dust impurities blown out by the automatic cleaner to move toward the storage box 31.

[0034] With such a design, when the automatic cleaner blows out an airflow, dust and impurities in the airflow will flow toward the storage box 31 along the inclined surface of the guide plate 5, thereby preventing dust and impurities from accumulating in the wall groove.

[0035] In one embodiment, the bottom surface of the first limiting strip 321 is provided with a second groove 3211;

[0036] A second limiting strip 6 corresponding to the second groove 3211 is provided on the first groove 12. When the second limiting strip 6 is inserted into the second groove 3211, the second limiting strip 6 is used to restrict the rotation of the limiting plate 32.

[0037] With such a design, when it is necessary to collect dust and impurities, the staff connects the storage box 31 to the dust-proof cover 1 and inserts the first limiting strip 321 on the limiting plate 32 into the first groove 12. After the storage box 31 is placed in a proper position, the staff releases the storage box 31. The storage box 31 descends under the influence of gravity and the second limiting strip 6 is inserted into the second groove 3211. At this time, the second limiting strip 6 restricts the rotation of the limiting plate 32, thereby preventing the storage box 31 from detaching from the dust-proof cover 1 due to accidental rotation of the limiting plate 32. When it is necessary to remove the storage box 31, the storage box 31 is lifted upward to separate the second limiting strip 6 from the second groove 3211, and then the limiting plate 32 is rotated downward to remove the storage box 31.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "a plurality of", "multiple groups", and "several" mean more than two.
