Abstract
The utility model belongs to the technical field of weaving equipment, specifically disclose a spool tube drawing device, including gripping clamping mechanism and fixing the impact mechanism on gripping the centre gripping framework, gripping clamping mechanism is used for the centre gripping spool, impact mechanism is used for strikeing the spindle repeatedly. The bobbin drawing device with the structure can solve the problem that the bobbin drawing action of the automatic doffer in the prior art fails due to the over-tight binding force.
Description
Technical Field
The utility model belongs to the technical field of weaving equipment, especially, relate to a spool tube drawing device.
Background
The spinning frame is a spinning machine which drafts, twists and winds semi-finished roving or sliver into spun yarn bobbin yarn in the spinning process, the production unit of the spinning frame is a spindle, the production level of the spinning frame is usually measured by the output (kilogram) per thousand spindle hours, and the bobbin is matched with the spindle for use. In the existing spinning frame, after an empty bobbin is loaded on a spindle, the bobbin is directly contacted with metal parts on the spindle, and because the processing sizes of the metal parts are different, the contact tightness between the bobbin and the spindle is different, so that the condition that the bobbin is contacted with the spindle too tightly exists, the bobbin drawing action of the automatic doffer fails to draw due to the excessive tight binding force, and the doffing success rate is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a spool tube drawing device to solve the tube drawing action of automatic doffer among the prior art and can be because of crossing the problem of inseparable cohesion tube drawing failure.
In order to achieve the above purpose, the technical scheme of the utility model is that: a bobbin drawing device comprises a holding clamping mechanism and an impact mechanism fixed on the holding clamping mechanism, wherein the holding clamping mechanism is used for clamping a bobbin, and the impact mechanism is used for repeatedly impacting a spindle.
The working principle of the technical scheme is as follows: when the bobbin needs to be pulled out, the holding and clamping mechanism falls for a certain distance from the upper part of the bobbin, clamps the bobbin and moves the bobbin upwards for a certain distance. Because the bobbin and the spindle are tightly combined, the spindle can also move upwards along with the bobbin. And starting the impact mechanism, and repeatedly impacting the spindle by the impact mechanism so as to separate the bobbin from the spindle and facilitate the subsequent tube drawing action to be implemented more smoothly.
The beneficial effects of this technical scheme lie in: the technical scheme is simple and convenient to operate, can quickly separate the spindle from the bobbin, and is convenient for smooth tube drawing action.
Further, the impact mechanism comprises a driving part and an impact shaft, and the driving part is used for driving the impact shaft to move along the axis of the impact shaft in a high-frequency reciprocating manner; and the axis of the impact shaft coincides with the clamping axis of the holding and clamping mechanism. This technical scheme can guarantee that impact mechanism can accurately strike the spindle.
Furthermore, the holding and clamping mechanism is a clamp holder such as an electric clamp holder, a pneumatic clamp holder or a hydraulic clamp holder.
Further, the gripping and clamping mechanism is capable of self-centering.
Further, the driving part is a cylinder or a linear motor.
Drawings
Fig. 1 is a schematic view of an embodiment of a bobbin drawing device of the present invention.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the bobbin holding and clamping device comprises a holding and clamping mechanism 1, a bobbin 2, a spindle 3, an impact shaft 4 and a driving part 5.
The embodiment is basically as shown in the attached figure 1: a bobbin drawing device comprises a holding clamping mechanism 1 and an impact mechanism, wherein the holding clamping mechanism 1 is used for clamping a bobbin 2, and the impact mechanism is used for repeatedly impacting a spindle 3. The holding and clamping mechanism 1 can be automatically centered, the holding and clamping mechanism 1 is a clamp such as an electric clamp, a pneumatic clamp or a hydraulic clamp, and the pneumatic clamp is adopted in the embodiment. The impact mechanism comprises a driving part 5 and an impact shaft 4, wherein the driving part 5 is a cylinder or a linear motor and the like, and the cylinder is adopted in the embodiment. The driving part 5 is fixed above the holding and clamping mechanism 1, the impact shaft 4 is connected with the driving part 5, and the driving part 5 is used for driving the impact shaft 4 to move repeatedly along the axis of the impact shaft 4 at high frequency; the axis of the impact shaft 4 coincides with the clamping axis of the gripping and clamping mechanism 1.
The specific implementation process is as follows:
when the bobbin 2 needs to be pulled out, the holding clamping mechanism 1 falls for a certain distance from the upper part of the bobbin 2, then clamps the bobbin 2 and moves the bobbin 2 upwards for a certain distance. Due to the tight combination of the bobbin 2 and the spindle 3, the spindle 3 can move upwards along with the bobbin 2. And starting the driving part 5, wherein the driving part 5 drives the impact shaft 4 to impact the spindle 3 repeatedly, so that the bobbin 2 is separated from the spindle 3, and the subsequent tube drawing action is implemented more smoothly.
The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
