Crimper side cover device {SIDE COVER DEVICE FOR CRIMPER}

The present invention relates to a side cover device for a crimper, and more specifically, it is installed on the side of the upper roller and the lower roller of the crimper to produce a cotton-like shape by regenerating PET (PET). To improve the side cover device that prevents the separation of the upper and lower rollers from the side, prolong the life and reduce the loss caused by the exchange to increase productivity and product quality.

In general, the inside of products that require cushioning and elasticity such as quilts, industrial non-woven fabrics, pillows, sofas, dolls, etc., was previously filled with cotton for a soft texture, but it is difficult to obtain natural cotton from the roots, but because it is expensive, Many alternatives that perform the same function are used.

No.

Although not mentioned in the prior art as described above, the side cover is attached to both sides of the upper and lower rollers to prevent the product supplied in the form of a thread or cotton filled into the cover assembly from being detached from the outside.

The side cover to which the prior art is applied maintains a fixed state in the frame in a state where the rectangular metal plate is in close contact with the center position of both sides of the upper and lower rollers, and is formed on both sides of the upper and lower rollers and the cutter assembly. (Gap) is prevented to prevent the cotton or wrinkled cotton of the upper and lower rollers from entering or exiting from the upper and lower rollers.

In this process, the side cover is in contact with the upper and lower rollers, and because the upper and lower rollers continue to rotate, a considerable amount of friction occurs and wear occurs easily, which usually has a life of about a week. After a certain period of time, the wear groove in the roller form is clearly exposed due to friction with the upper and lower rollers, and it is impossible to perform the hermetic role.

In particular, when looking at the wear condition of the side cover, it is necessary to recycle (reuse) the side cover because the wear occurs in the form of intrusion only in the part in close contact with the upper and lower rollers, and in other parts, the wear degree is weak or there is no wear. It is difficult, so always replace it with a new side cover.

In this case, the entire drawing part having the crimper as well as the crimper is stopped, the side cover is replaced with a new one, and the devices are operated again to periodically repeat the process of producing the product.

In this way, productivity decreases due to a long idle time in which the entire device needs to be stopped for side cover replacement, as well as unnecessarily high manpower consumption due to frequent replacement work and maintenance cost and time due to the use of replacement parts. There is a disadvantage that it takes too much.

In addition, when the device is stopped to replace the side cover, the device of the material material is not maintained in a normal state in the process of passing through the crimper before passing through the crimper, and is exposed to an abnormal state for a replacement time. When the product is restarted, it is not free from various problems such as the quality of the product being produced is not uniform.
