Description

Technical Field

[0001] The utility model relates to the technical field of cradle limiting devices, in particular to a cradle semi-pressing component of a spinning frame. Background Art

[0002] In the current spinning industry, spinning frames play a vital role in the production process of spinning mills. However, during the spinning process, when the spinning frame needs to be stopped for maintenance due to various reasons, an easily overlooked but extremely important operating detail is the handling of the cradle.

[0003] When the spinning frame is stopped for maintenance or inspection, if special attention is not paid and the cradle is not opened, the long-term stop state will directly cause the top roller to deform due to continuous force. This deformation not only shortens the service life of the top roller, but also has a direct negative impact on the quality of spinning. This is because the deformed top roller is no longer stable after restarting, which affects the quality and consistency of the yarn.

[0004] On the other hand, in order to avoid deformation of the top roller, some operators will choose to lift the handle of the cradle when stopping the machine. In this way, the pressure relief of the top roller will cause the pressure of the cradle on the yarn to be released, and the top roller will be displaced. This displacement often causes the sliver on the roller to break, which is a great damage to the continuity of the yarn and production efficiency.

[0005] When the maintenance work is completed, the handle is pressed again to lock the cradle, and the spinning frame is restarted, and problems arise one after another. Due to the disconnection of the sliver, the operator must re-join the yarn. This not only increases their workload, but more importantly, the quality of the yarn at the joint is often difficult to compare with the original yarn, thus affecting the overall yarn quality. Summary of the invention

[0006] The utility model aims to provide a spinning frame cradle semi-pressure component to address the deficiencies of the above prior art, so as to achieve the purpose of making the cradle in a semi-pressure-released state after the cradle handle is opened after the spinning frame is stopped.

[0012] Compared with the prior art, the utility model has the following outstanding beneficial effects:

[0013] The utility model can ensure that after the spinning frame stops, the cradle is in a semi-depressurized state after the cradle handle is opened, and the pressure of the leather roller is reduced from 150N-200N in the working state to 30-100N. Even if it does not work for a long time, it is not easy to deform and does not move, ensuring that the yarn will not be broken after the cradle is locked again, reducing the workload of yarn joints and improving the yarn quality.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figures 1 to 5 As shown, the utility model includes a limit pull rod 3 and a fixing seat 2.

[0023] The upper end of the limit rod 3 is fixedly connected to the knob 1, and the lower end of the limit rod 3 is connected to the limit block 4. A slot corresponding to the shape of the limit rod 3 and the limit block 4 is provided in the middle position of the fixed seat 2. The limit rod 3 and the limit block 4 pass through the fixed slot on the fixed seat 2, and the limit rod 3 cooperates with the fixed slot of the fixed seat 2.

[0024] The cross-sectional area of ​​the knob 1 is larger than the cross-sectional area of ​​the limit pull rod 3, so that the knob 1 can be hung on the upper end surface of the handle of the cradle.

[0025] The handle and the body of the cradle are provided with clearance slots, the fixing seat 2 is placed inside the molding cavity of the handle, and the limiting rod 3 and the limiting block 4 pass through the clearance slot of the handle, the fixing slot of the fixing seat 2 and the clearance slot on the body in sequence. In normal use, the limiting rod 3 can smoothly pass through the clearance slot of the body when moving up and down with the handle. In the semi-release state, the limiting rod is rotated 90° so that the hook at its lower end is stuck on the inner wall of the body.

[0026] In Example 1, the limiting pull rod 3 is in a cylindrical structure, a first annular protrusion 31 is provided on the outer surface of the limiting pull rod 3, a second annular protrusion 21 is provided on the inner wall of the fixing slot of the fixing seat 2, the lower end of the limiting pull rod 3 passes through the fixing slot of the fixing seat 2, the first annular protrusion 31 is squeezed through the second annular protrusion 21, and the first annular protrusion 31 is placed at the lower end of the second annular protrusion 21, so that the limiting pull rod 3 and the fixing seat 2 are completely clamped.

[0027] The limiting block 4 is a convex block, and the lower end of the limiting pull rod 3 is vertically connected to the convex block.

[0028] In the optimized solution, the limiting pull rod 3 is provided with grooves on the outer surfaces of the upper and lower ends of the first annular protrusion 31 to reduce the force generated by the deformation of the first annular protrusion 31 when it slides over the second annular protrusion 21, making it easy to insert.

[0029] like Figure 6 As shown, in Example 2, the upper portion of the limit rod 3 is a T-shaped plate structure, and the bottom is a hook plate structure. The outer side of the horizontal plate of the T-shaped limit rod 3 is sleeved with a knob 1, and the middle of the vertical plate has a step.

[0030] The fixing seat 2 is sleeved on the outer side of the limiting pull rod 3 through the fixing slot, and the fixing seat 2 is limited and fixed by the step of the limiting pull rod 3.

[0031] In this embodiment, the fixing seat 2 is made of rubber material, and the limiting pull rod 3 can open the fixing slot hole of the fixing seat 2 and pass through the fixing slot hole of the fixing seat 2 .

[0032] The operation process is as follows: when using the utility model, the fixing seat 2 is placed inside the molding cavity of the handle, and the limiting pull rod 3 passes through the clearance slot of the handle, the fixing slot of the fixing seat 2 and the clearance slot on the body in sequence. In the normal use state, the limiting pull rod 3 can smoothly pass through the clearance slot of the body when the handle moves up and down. In the semi-release state, the limiting pull rod is rotated 90° so that the hook at its lower end is stuck on the inner wall of the body, ensuring that the cradle is in a semi-release state after the cradle handle is opened after the spinning frame stops.

[0033] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes to the present invention without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
