Description

Drawing frame capable of automatically breaking

Technical Field

The utility model relates to a textile machinery field, especially a drawing frame that can automatic disconnected strip.

Background

The drawing frame is used for improving the internal structure of the sliver, thereby improving the uniformity of long sections of the sliver, simultaneously reducing the weight unevenness, straightening and paralleling fibers in the sliver, reducing hooks, enabling the fineness to accord with the specification, and enabling raw materials of different types or different qualities to be uniformly mixed to achieve the specified mixing ratio. Drawing frames are classified into roller drawing frames and gill boxes according to the form of a drawing mechanism. The existing drawing frame has a common problem that the strip needs to be broken manually after the coiling barrel is filled with the materials, so that the production yield is greatly reduced.

SUMMERY OF THE UTILITY MODEL

In view of the above, the utility model aims to provide a drawing frame that can automatic disconnected strip can realize the automatic disconnected strip of wool tops.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the utility model provides a drawing frame that can automatic disconnected strip, includes the drawing frame body and sets up in the automatic disconnected strip device of the coiling dish below of drawing frame body, automatic disconnected strip device includes the fixed block and sets up the activity disconnected strip mechanism relatively with the fixed block, activity disconnected strip mechanism includes that the level sets up and with the fixed block just right telescopic cylinder mutually, telescopic cylinder's telescopic link tip sets firmly the movable block, and movable block relatively fixed block one side sets up the recess, sets up the dwang in the recess, and articulated just the upper end is to the dead lever slope with the recess in the middle of the dwang, and the upper end of dwang sets up the thimble, and the dwang lower extreme sets up cuts the board, after the movable block supported tight fixed block, cut the piece and rotate to with fixed block lower.

Further, set up reset spring in the recess, reset spring one end and movable block fixed connection, the other end and dwang upper portion fixed connection and make the dwang upper end slope towards the fixed block.

Furthermore, one end of the thimble opposite to the fixed block is of a hemispherical structure.

The working principle is as follows: and finishing drawing after the cotton sliver in the sliver winding barrel is wound. And then the telescopic cylinder stretches out to drive the cotton sliver to be close to the fixed block, and after the thimble is contacted with the fixed block, the fixed block pushes the rotating rod to rotate through the thimble. Meanwhile, the shearing plate arranged at the lower end of the rotating rod rotates towards the direction of the fixed plate, and after the shearing plate rotates to be in contact with the lower surface of the fixed block, shearing force is generated between the shearing plate and the fixed block, and the cotton sliver is cut off. When the cotton sliver is cut off, the telescopic cylinder retracts to the initial position, and then the sliver winding barrel is taken out of the drawing frame. The sliver is then sent to the next sliver can for collection.

Has the advantages that: through above-mentioned structure, realized the automatic cutout of silver, promoted production efficiency.

Reference numerals: 100, and adjusting the body 110, the coiling disc 200, the automatic strip breaking device 210, the fixed block 220, the movable strip breaking mechanism 221, the telescopic cylinder 222, the movable block 223, the groove 224, the rotating rod 225, the thimble 226, the cutting plate 227 and the return spring.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The drawing frame capable of automatically breaking as shown in fig. 1 to 3 includes a drawing frame body 100 and an automatic breaking device 200 disposed below a coil drum 110 in the drawing frame body. Specifically, the automatic strip breaking device comprises a rectangular fixed block 210 and a movable strip breaking mechanism 220 arranged opposite to the fixed block. The movable broken bar mechanism specifically comprises a telescopic cylinder 221 which is horizontally arranged, and a telescopic rod of the telescopic cylinder is arranged right opposite to the fixing block. A movable block 222 is fixedly connected to the end of the telescopic rod, a groove 223 is formed in one side of the movable block, which faces the fixed block, a rotating rod 224 is arranged in the groove, the middle of the rotating rod is hinged to the movable block, and the upper end of the rotating rod inclines towards the fixed block. Meanwhile, the upper end of the rotating rod is also provided with a thimble 225, and the end of the thimble faces the fixed block. And a cutting plate 226 is provided at the lower end of the rotating rod. Specifically, when the dwang rotated to vertical state, what the cutting plate laminated supported tightly on the lower surface of fixed block to form a shearing action to the silver.

As a further improvement of the above embodiment, in order to ensure the state of the rotating rod when the rotating rod is not acted by the fixed block, a return spring 227 is further arranged in the groove, one end of the return spring is fixedly connected with the movable block, and the other end of the return spring is fixedly connected with the upper part of the rotating rod. When the thimble is pressed, the reset spring is pressed, when the movable block is separated from the contact with the fixed block, the reset spring returns to the initial state, and the rotating rod returns to the state that the upper end inclines towards the fixed block.

As a further improvement of the above embodiment, in order to ensure the smoothness of the rotation of the rotating rod, one end of the thimble facing the fixed block is of a hemispherical structure.
