Description

Technical Field

[0001] The present application relates to the technical field of glass fiber chopped short-cut equipment, and in particular to an active yarn joining and suction mechanism of an automatic head-loading continuous online short-cutting machine. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance and comes in many varieties. It is characterized by heat resistance, corrosion resistance, good insulation properties and high mechanical strength. It is usually used as a reinforcing material in composite materials and is widely used in national economic fields such as aerospace, transportation, mechanical electronics, and building materials.

[0003] One of the purposes of chopped glass fiber yarn is to cut the glass fiber yarn into suitable sizes for use so as to process it into the required products. For example, the chopped glass fiber yarn segments are added to cloth or sheet materials and then made into glass fiber cloth or glass fiber sheet materials through adhesives and other raw materials.

[0004] A chopper is a specialized piece of equipment used to chop glass fibers. The chopper unit is typically equipped with a rubber roller and a knife roller, which work together to continuously chop the glass fibers. A continuous chopper typically consists of a turntable and two chopper units. The turntable rotates to swap the two units, ensuring continuous chopping and allowing maintenance on damaged units.

[0005] The existing problem is that the short-cutting operation is still in progress during the rotation of the short-cutting unit, which will cause the yarn cut by the working short-cutting unit to be repeatedly cut by the standby short-cutting unit. In the process of cutting and rotating, short-cut yarn particles will be splashed everywhere to pollute the environment, and the short-cut yarn particles will be uneven in length and the hairiness will increase, thereby reducing the quality.

[0006] For current short-cut equipment, please refer to:

The yarn unloading door driving component 30 is a linear telescopic cylinder, and the interlocking cylinder 410 is a linear telescopic cylinder.

[0037] The yarn receiving box 10 includes a front box plate 160, a rear box plate 170, and a middle box plate 180. The front box plate 160 and the rear box plate 170 are fastened together by the middle box plate 180. The front box plate 160, the rear box plate 170, and the middle box plate 180 define a yarn inlet 110, a yarn suction port 120, and a yarn discharge port 130.

[0038] The yarn receiving box 10 is provided with a rotating shaft seat 140, and the yarn unloading door 20 is provided with a side rotating shaft 210. The yarn unloading door 20 is hinged to the yarn receiving box 10 through the cooperation of the side rotating shaft 210 and the rotating shaft seat 140. The yarn unloading door driving component 30 is fixedly assembled on the front box plate 160, and the piston rod of the yarn unloading door driving component 30 is hinged to the yarn unloading door 20.

[0039] The piston rod of the yarn unloading door driving component 30 can drive the yarn unloading door 20 to open or close the yarn unloading port 130 when performing telescopic motion.

[0040] The interlocking cylinder 410 is provided on the short cutting unit, and the interlocking rod 420 is provided on the piston rod of the interlocking cylinder 410. The interlocking cylinder 410 can drive the interlocking rod 420 to perform telescopic movement through its piston rod.

[0041] The yarn splicing box 10 is further provided with a connecting piece 150, and the connecting piece 150 is provided with a connecting hole 1510. The connecting hole 1510 is used to fix the yarn splicing box 10 under the knife roller and the rubber roller of the short cutting machine unit.

[0042] When the chopping unit performs normal chopping operation, the yarn unloading door 20 is in an open state, and the chopped yarns from the knife roller and rubber roller of the chopping unit can fall onto the finished yarn conveyor belt through the yarn unloading port 130.

[0043] When the short-cutting machine group is circulating or rotating, the yarn unloading door 20 is in a closed state, and the upper yarn from the short-cutting machine group is collected in the yarn receiving box 10 and sucked into the yarn suction telescopic tube 50.

[0044] The yarn suction telescopic tube 50, the yarn suction tube driving component 60 and the yarn suction head 70 are used to complete the follow-up collection and suction of the yarn on the short-cutting machine unit.

[0045] The suction tube drive component 60 is a slide cylinder. The suction tube 50 and the suction tube drive component 60 are both mounted on the frame of the short-circuit machine. A suction head 70 is mounted on the suction tube 50 and fixedly connected to the cylinder slide of the suction tube drive component 60. The suction head 70 is able to move up and down under the control of the suction tube drive component 60.

[0047] Principle and effect description: When the short-cutting unit circulates or rotates, the cylinder slide of the yarn suction tube driving component 60 drives the yarn suction head 70 and the yarn suction telescopic tube 50 to rise together with the short-cutting unit; the short-cutting unit rises while cutting, and the yarn unloading door 20 is in a closed state at this time, and the short-cut yarn is collected into the yarn receiving box 10 and sucked into the yarn suction telescopic tube 50 through the yarn suction port 120; after the short-cutting unit reaches the standby station, the cylinder slide drives the yarn suction head 70 and the yarn suction telescopic tube 50 to return to the working station, and docks them to the yarn suction port 120 of the yarn receiving box 10 at the working station through the yarn unloading docking interface of the yarn suction head 70. When the yarn suction head 70 follows the short-cutting unit to collect and suck the yarn, the interlocking rod 420 extends into the interlocking hole on the yarn suction head 70 to increase the smoothness of the movement of the yarn suction head 70 and the yarn suction telescopic tube 50; when the yarn suction telescopic tube 50 and the yarn suction head 70 return to the working station, the interlocking rod 420 exits the interlocking hole to release the lock between the yarn suction head 70 and the interlocking rod 420.

[0048] Therefore, the active yarn joining and suction mechanism provided in the present application, through the cooperation of the yarn joining box, the interlocking mechanism, the yarn suction telescopic tube, and the yarn suction tube driving components, can perform a fully closed recovery process on the chopped yarns produced during the unit circulation process. On the one hand, it can avoid the chopped yarns being repeatedly chopped by two chopped units and affecting the product quality.
