Description

A kind of cotton guide and impurity removal device for drawing frame

technical field

The utility model relates to a cotton spinning device, in particular to a cotton guiding and impurity removing device for a drawing frame.

Background technique

Since 2015, our company has successively introduced 16 sets of Hubei Tianmen TMFD81S draw frames. The equipment has advanced design, high degree of automation, high quality and high output, energy saving and high efficiency. The overall operation has been good in the past two years, but a major disadvantage has been found during the use process, that is, the combination of the cotton guide plate is easy to steal the sliver, resulting in unqualified quality of the sliver or changes in the proportion of cotton.

Utility model content

The technical problem to be solved by the utility model is to provide a cotton guide and impurity removal device for the drawing frame. During the process of cotton guide, the device will not suck the cotton sliver at the strip tuyere, effectively ensure the proportion of cotton input, and improve the Draw the product quality; In addition, this product can also improve the effect of impurity removal.

In order to solve the above technical problems, the utility model adopts the following technical means:

A cotton guide and impurity removal device for a draw frame, comprising a negative pressure box, the negative pressure box is provided with a top plate, and the top plate of the negative pressure box is used as a cotton guide plate for a draw frame, and the cotton guide plate for a draw frame, etc. Strip tuyere is arranged at intervals, and the strip tuyere is perpendicular to the conveying direction of the cotton sliver. The inner wall of the cotton guide plate of the drawing frame is provided with a honeycomb hole grid. The grid is nested in the strip tuyere and the upper surface of the honeycomb hole grid is flush with the upper surface of the cotton guide plate of the draw frame.

By setting the honeycomb hole grid at the strip tuyere, the conveyed sliver is supported by the honeycomb hole grid at the strip tuyere, and the sliver will not be sucked into the strip tuyere, avoiding the phenomenon of "stealing cotton"; In addition, the added grid of the honeycomb grid makes the conveyed sliver vibrate when it passes by, which improves the detachment of impurity particles in the sliver under the action of wind, thereby improving the effect of impurity removal; the honeycomb grid and the strip The upper surface of the tuyere is flush, which can prevent the occurrence of lint hanging.

Further optimal technical scheme is as follows:

The honeycomb grid is provided with a frame plate, and the frame plate is provided with a connecting seat, and the honeycomb grid is connected and fixed with the inner wall of the cotton guide plate of the draw frame through the connecting seat.

By setting the frame plate, the honeycomb hole grid is connected and fixed to prevent it from detaching from the strip tuyere; the connection seat is provided to help the connection and fixation of the honeycomb hole grid through the connection seat; the above connection and fixation can be bolted or glued. Connecting, preferably bolting, can replace the honeycomb grid with different apertures for different sliver.

The frame plate is provided with reinforcing beams, the reinforcing beams are located on the connecting line of the center of the strip tuyere, the top of the reinforcing beam is provided with a supporting rib, and the length of the supporting rib is greater than the width of the reinforcing beam and shorter than the length of the strip tuyere.

By arranging reinforcing beams and supporting ribs on the reinforcing beams, the deformation of the honeycomb grid at the strip tuyere can be prevented, and the stability of the device can be further improved.

Both ends of the strip tuyere are arc-shaped.

The above settings can prevent the phenomenon of cotton hanging in the process of conveying the sliver.

Detailed ways

Below in conjunction with embodiment, further illustrate the utility model.

Referring to Fig. 1 and Fig. 2, it can be known that a drawing frame cotton guiding impurity removal device of the present invention is composed of a drawing frame cotton guiding plate 1 and a honeycomb hole grid 3; the negative pressure box 8 is provided with a top plate, and the negative pressure box The top plate of the body 8 is used as the cotton guide plate 1 of the draw frame machine, and strip tuyere 2 is arranged at equidistant intervals on the draw frame cotton guide plate 1, and the strip tuyere 2 is perpendicular to the conveying direction of the sliver, and the draw frame cotton guide plate 1 The inner wall of the honeycomb grid 3 is provided with a honeycomb grid 3, and the position corresponding to the strip tuyere 2 protrudes upward so that the honeycomb grid 3 is nested in the strip tuyere 2 and the upper surface of the honeycomb grid 3 and the draw frame The upper surface of the cotton guide plate 1 is flush.

Drawing frame cotton guide plate 1 is pressed by the steel plate of 2mm, has the long 15cm, the wide 1cm air filling port in the middle, and the spacing of filling air port is 4cm.

Referring to Fig. 3 and Fig. 4, it can be seen that the honeycomb grid 3 is provided with a frame plate 4, and the frame plate 4 is provided with a connecting seat 6, and the honeycomb grid 3 is connected and fixed to the inner wall of the cotton guide plate 1 of the drawing frame through the connecting seat 6 .

By setting the frame plate 4, the honeycomb grid 3 is connected and fixed to prevent it from breaking away from the strip tuyere 2; the connecting seat 6 is provided to help the connection and fixing of the honeycomb grid 3 through the connecting base 6; the above-mentioned connection and fixing can be bolts Connecting, also can be bonding, preferably bolting, can change the honeycomb grid 3 of different apertures to different sliver.
