Description

A yarn end automatic clamping and fixing device

technical field

The invention belongs to the technical field of textile machinery, in particular to a yarn end automatic clamping and fixing device.

Background technique

As the front process of weaving carpets, winding plays an important role. The winder rewinds the skein into yarn balls, changes the package form of the yarn, forms a yarn ball with a suitable yarn capacity, and removes various defects on the yarn at the same time.

The winder has multiple units working at the same time, and each unit simultaneously winds the skein into yarn clusters. When a unit of the winder starts to wind a yarn ball, the worker needs to fix the yarn end of the skein on the mandrel of the yarn ball first, and then wind the yarn on the mandrel by the winding mechanism of the winder Form a yarn ball on top. When the length of the yarn cluster reaches the requirement, the worker stops the winding mechanism, cuts the yarn between the skein and the yarn cluster, removes the wound yarn cluster, and then fixes the yarn end on the mandrel to carry out Winding of the next bobbin. The winding speed of the winder is fast, and the preparation before winding and the removal of the yarn cluster after winding must be completed by workers. The bobbin is removed and a new bobbin is wound.

Existing winder is manually operated by worker, and the yarn end of skein is fixed on the mandrel of yarn group by worker. The winding speed of the winder is fast, and the worker must remove the yarn cluster that reaches the required length in time, and fix the yarn end of the skein on the mandrel. This has just determined that the number of winder units that a worker can be responsible for is very limited, and when a large number of winder units are required to work simultaneously, the number of workers required is also very large.

The yarn head fixing method of the existing winder has the following disadvantages: it is manually operated by workers, and when the number of winder units is large, it takes a lot of labor and is time-consuming and labor-intensive.

Contents of the invention

The technical problem to be solved by the present invention is to provide a yarn end automatic clamping and fixing device, which can replace the worker to fix the yarn end, automatically fix the yarn end of the skein on the yarn ball mandrel, and solve the problem of winder operation process. There is a problem that a large number of workers must perform the fixing operation of the yarn end of the skein.

The technical solution adopted by the present invention to solve the technical problem is to provide a yarn end automatic clamping and fixing device, which includes a yarn ball mandrel, a yarn clamping hand and a yarn winding rod, and the yarn ball mandrel passes through the mounting frame Installed on the guide rail and reciprocating along the guide rail, the lower end of the installation frame is slidingly connected with the guide rail, and a cylinder is fixedly installed on the installation frame, and the piston of the cylinder is connected upward to the ejector rod, and the lower part of the ejector rod is covered with a spring. The other end of the spring is connected to the installation frame, the upper part of the ejector rod is installed in the hollow yarn mandrel, and the upper end extends out of the hollow yarn mandrel to connect the yarn end gland, and the yarn winding rod is equipped with yarn, so that A yarn grabbing manipulator is installed above the yarn winding rod and the yarn cluster mandrel.

The yarn grabbing manipulator includes a horizontal rack and pinion driving device connected to the main frame body to control the reciprocating movement of the main frame body in the horizontal direction. A vertical driving screw device is installed on the main frame body, and the vertical driving screw rod device is connected to The slider, the vertical drive screw device controls the slider to reciprocate in the vertical direction, and the yarn gripper and electric scissors are installed on the slider.

Beneficial effect

Because the present invention adopts the scheme of fully automatic fixing the yarn end, the operation of fixing the yarn end of the automatic winder is completed by machinery, which reduces the dependence of the automatic winder on workers and improves the degree of automation of the automatic winder.

Detailed ways

Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

As shown in Figures 1 and 2, a yarn end automatic clamping and fixing device includes a yarn ball mandrel 9, a yarn gripper 5 and a yarn winding rod 2, and the yarn ball mandrel 9 is installed on the On the guide rail, along the guide rail for reciprocating movement, the lower end of the mounting frame is slidingly connected with the guide rail, and the cylinder 11 is fixedly installed on the mounting frame, and the piston of the cylinder 11 is connected upward to the ejector rod 8, and the lower part of the ejector rod 8 is covered with Spring 10, the other end of the spring 10 is connected to the installation frame, the upper part of the push rod 8 is installed in the hollow yarn mandrel 9, and the upper end extends out of the hollow yarn mandrel 9 to connect the yarn end gland 7, the yarn roll Yarn 1 is housed on the winding rod 2, and a yarn grabbing manipulator is installed above between the yarn winding rod 2 and the yarn cluster mandrel 9.

The yarn grabbing manipulator 10 includes a horizontal rack and pinion driving device 3 connected to the main frame body to control the horizontal reciprocating movement of the main frame body. A vertical driving screw device 4 is installed on the main frame body, and the vertical driving screw mandrel The device 4 is connected with a slide block, and the vertical drive screw device 4 controls the slide block to reciprocate in the vertical direction, and the yarn gripper 5 and the electric scissors 6 are installed on the slide block.

In practical applications: the winding rod 2 winds the yarn 1 on the yarn ball mandrel 9, and when the winder finishes winding a yarn ball, the yarn winding rod 2 Fixed, the vertical drive screw device 4 drives the yarn gripper 5 to move down to the winding rod 2, the yarn gripper 5 grips the yarn 1, and the yarn cluster The mandrel 9 and the yarn cluster are driven by the driving device to withdraw to the right as a whole, and then the yarn between the yarn gripper 5 and the yarn cluster mandrel 9 is cut by the electric scissors 6, and the yarn cluster is taken away.
