Description

Technical Field

[0001] The utility model specifically relates to a quilt fabric roll anti-stretching mechanism and belongs to the technical field of weaving equipment. Background Art

[0002] When the quilt fabric is being cut, the material roll needs to be unrolled for intermittent feeding. The material roll will continue to rotate due to inertia, causing the fabric to droop to the ground. Some more expensive fabrics will become dirty, causing trouble for subsequent processing.

[0003] In order to solve this problem, we first adopted the method of manually watching the material rolls. When the feeding stopped, we blocked the material rolls with our hands to reduce the inertia of the material rolls and reduce the drooping of the fabric. However, there was a risk of being hit and scratched by human hands. Later, we used tools to avoid direct contact with human hands. However, in this case, the workers were highly nervous and easily fatigued.

[0004] In order to solve this problem, the technical personnel of our company provide a cloth roll anti-stretching mechanism, which can automatically brake the material roll when the cloth droops. Utility Model Content

[0005] The utility model aims to provide a quilt fabric roll anti-stretching mechanism to solve the above-mentioned shortcomings.

[0006] The technical solution adopted by the utility model is: a quilt fabric roll anti-stretching mechanism, comprising a bracket, wherein the bracket comprises side frames located on both sides of the roll of the feeder;

[0007] A mounting back plate is connected to the side frames on both sides, and the cylinder is mounted on the mounting back plate;

[0008] A shaft is also connected to the side frames on both sides and the shaft is located on the upper part of the mounting back plate, and a rotating brake block is provided on the shaft body of the shaft and rotates around the axis of the shaft;

[0009] A push frame is installed at the head of the piston rod of the cylinder, and the push frame abuts against the lower surface of the rotating brake block and pushes the rotating brake block to rotate around the axis;

[0010] The rotating brake block is located below the material roll;

[0011] The mounting frame is mounted on the bracket through a connecting shaft and is located above the shaft. A contact sensor is installed in front of the mounting frame. The fabric is first led out from the top of the guide roller of the feeder from the material roll, and the contact of the contact sensor contacts the top of the fabric. When the fabric is detached, it is detected by the contact of the contact sensor, and then the cylinder is activated to push the rotating brake block against the material roll.

[0012] Beneficial Effects

[0013] This device adopts a contact sensor set on the detection frame. When the fabric leaves the sensor, the cylinder is activated to push the rotating brake block against the material roll to achieve the braking purpose and reduce the inertia of the material roll.

[0014] Compared with the traditional direction, this device has a high degree of automation and does not require human supervision. The brakes will be applied when the fabric leaves the contact sensor, which is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS
