Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
The first embodiment is as follows:
referring to fig. 1 to 4, the electronic yarn cutting and holding integrated device of the present embodiment includes a rotating arm 2 driven by a rotation driver 1 to rotate, and a fixing arm 3 located on one side of the rotating arm, wherein one of the rotating arm and the fixing arm is provided with a buffer block 4, the other of the rotating arm and the fixing arm is provided with a yarn cutting and holding assembly, the yarn cutting and holding assembly includes a pressing block 5 and a yarn cutting blade 6, the yarn cutting blade is fixedly arranged on the rotating arm or the fixing arm, the pressing block is connected with the rotating arm or the fixing arm through an elastic device, a cutting edge of the yarn cutting blade is located on the lower side of the top surface of the pressing block, and the rotating arm can drive the buffer block or the yarn cutting assembly to rotate, and the cutting edge of the yarn cutting blade protrudes out of the top surface of the pressing block.
The electronic yarn cutting and holding integrated device of the embodiment drives the rotating arm to rotate through the rotating driver, and cuts and holds weft yarns through the buffer block and the yarn cutting and holding assembly. Compared with the original edge folding device, the rotary driver replaces airflow driving, weft yarn is held, the cutting function is integrated on the rotary arm or the fixed wall through the yarn cutting blade, the weft yarn can be held and cut, and therefore the integration level and the compactness of the device are improved.
The electronic yarn cutting and holding integrated device avoids a scissor transmission mechanism and a large amount of high-pressure gas required by holding through high-pressure airflow originally, so that the cutting and holding functions can be realized only by one gas circuit and one electromagnetic valve when the device is used for folding edges, the airflow is greatly saved, the cost is obviously reduced, and the problems of high gas consumption and unstable folding edges are solved.
In addition, compared with the original mode of holding the weft yarn inside the folding block, the electronic yarn shearing and holding integrated device holds the weft yarn outside the folding block through the buffer block and the pressing block, so that the length of the weft yarn bearing folding airflow is increased, and the stability of weft yarn folding is further improved.
During specific work, the electronic yarn cutting and holding integrated device is arranged on one side of the folding block 7. The weft yarn is transferred between the rotating arm and the fixed arm through the slot 8 on the tuck-in block. Then, the rotating arm is driven by the rotating driver to rotate so as to drive the buffer block or the yarn cutting holding assembly at the end part to rotate around the connecting shaft of the rotating arm.
After the rotating arm rotates to the position where the buffer block or the pressing block is contacted with the weft yarn, the rotating arm continues to rotate and drives the weft yarn contacted with the rotating arm to move towards the end part of the fixed arm. When the rotating arm rotates to the position where the buffer block is in contact with the pressing block, the buffer block and the pressing block are extruded, the pressing block overcomes the elastic force of the elastic device under the action of the pressure and contracts inwards until the yarn cutting blade extends out of the lower portion of the top surface of the pressing block, and weft yarns between the buffer block and the pressing block are cut until the weft yarns are cut off.
After the weft yarn is cut off, the weft yarn is not retracted due to the action of the elastic device and is still held between the buffer block and the pressing block, so that the function of holding the cut weft yarn is realized. And at the required folding angle, the rotating arm rotates reversely and loosens the weft yarns, and the devices sequentially and circularly reciprocate according to the process to cut and hold the weft yarns.
As can be seen from the above description, because the pressing block and the yarn cutting blade are integrated on the rotating arm or the fixed arm, the cutting transmission mechanism is not only eliminated, but also the holding and yarn cutting can be made very thin, and the length of the weft yarn at the edge folding is shortened. Meanwhile, the rotating arm can be designed into a specific shape so as to automatically push the weft yarns into the slot bottom of the folding edge block.
When the yarn cutting device is specifically implemented, the buffer block can be arranged on the rotating arm or the fixed arm, and correspondingly, the yarn cutting holding assembly can be arranged on the other arm between the rotating arm and the fixed arm.
In this embodiment, the tip of rotor arm is equipped with the fixed slot, and the buffer block inlays in this fixed slot. The buffer block is integrally I-shaped, the fixing groove penetrates through the rotating arm, the top of the I-shaped buffer block is embedded in the fixing groove, and the bottom of the I-shaped buffer block is attached to the surface of the rotating arm. In addition, the operator can further fix the buffer blocks in the fixing grooves through bolts. The buffer block can be made of materials with certain elasticity and self-lubricating function, such as polytetrafluoroethylene and the like.

The top of mounting groove still is provided with and is used for spacing stopper 10 to the briquetting. The pressing block moves outwards under the action of the elastic force of the spring until contacting with the limiting block. At the moment, the top surface of the pressing block protrudes out of the surface of the fixed arm and is higher than the cutting edge of the yarn cutting blade.
When the buffer block extrudes the pressing block under the driving of the rotating arm, the pressing block overcomes the elasticity of the spring and contracts towards the inside of the mounting groove until the top surface of the pressing block is slightly lower than the cutting edge of the yarn cutting blade, so that the yarn cutting blade is exposed from the lower part of the pressing block and cuts weft yarns.
The yarn cutting blade is fixedly arranged on the side surface of the fixed arm through a screw, and the cutting edge of the yarn cutting blade is lower than the top surface of the pressing block.
The rotary driver is a device with a rotary driving function, and can be a pneumatic or electric component, such as a rotary cylinder, an alternating current/direct current motor and the like. In this embodiment, the rotation driver is preferably a rotary electromagnet, and an output end of the rotary driver is fixedly connected with one end of the rotating arm. The end of the fixed arm can be directly fixed on the shell of the motor.
In this embodiment, the rotating arm is in a V shape, and one end of the rotating arm is provided with a connecting ring 11 connected with the output shaft of the motor. The inner side surface of the connecting ring is provided with a plane so as to be connected with the output shaft of the motor conveniently.
The fixing arm comprises an arc-shaped part 12 fixedly connected with the motor shell and a flat part 13 used for installing and holding the yarn cutting assembly. When the weft yarn clamping device is installed, the pressing block and the buffer block are approximately located in the same circumference, so that the buffer block and the pressing block can be driven by the rotating arm to contact and hold weft yarns.
The folding block is an existing part, the body of the folding block is of a V-shaped structure, and a slot opening extending from the bottom of the V-shaped groove is formed in the V-shaped body. In operation, the ends of the weft yarn pass from the slot and are conveyed between the buffer block and the compact.
The second embodiment:
referring to fig. 5, the electronic yarn cutting and holding integrated device of the present embodiment is consistent with the electronic yarn cutting and holding integrated device of the first embodiment in basic principle, except that the installation positions of the buffer block and the yarn cutting and holding component are exchanged.
