Description

Technical Field

[0001] The invention relates to the technical field of artificial turf yarn production equipment, and more particularly to a winding machine for artificial turf yarn. Background Art

[0002] The raw materials currently used in the artificial turf production industry are mainly polyethylene (PE), polypropylene (PP) and nylon (PA). Compared with various cotton yarns and chemical fiber yarns in the textile field, artificial turf yarn has more strands, a larger single yarn weight, a greater material breaking strength, better toughness, and a heavier weight after being fully rolled. In the production process of artificial turf yarn, the grass yarn roll needs to be replaced with an empty tube after winding. Before replacement, the grass yarn of the fully rolled grass yarn roll needs to be cut off. When replacing, the cut grass yarn needs to be wound onto the empty tube and the grass yarn tail is reserved.

[0003] At present, the domestic artificial turf production industry generally adopts domestic manual winding machines, which have only a single winding function. When operating, the operator first stops the grass winding machine, then cuts the grass with scissors, and then changes the full roll of grass and winds the empty tube. The operations of breaking the wire, changing the tube, winding the grass onto the empty tube and reserving the grass tail are all done manually, which has high labor intensity and low production efficiency, and also has relatively high requirements on the operator's operating skills and proficiency.

[0004] The existing automatic yarn breaking device of an artificial grass winding machine, such as the one disclosed in Chinese patent 201910707714.9, has a tube mounted on a winding shaft directly connected to a motor, and rotates with the winding shaft for active winding. The automatic yarn breaking function has a low cutting rate when cutting heavy grass strands. Moreover, when the grass strands are relatively long, the grass strands are easily entangled on the winding shaft by the rotation of the winding shaft motor and the tightening of the grass strands by the blades. The winding action is complicated and the production cost is high. The full grass strand roll needs to be removed manually, and the empty tube needs to be loaded manually.

[0005] SAHM of Germany is a world-leading manufacturer of automatic and manual winding machines. Its equipment can meet the needs of various different yarns, such as composite filaments, monofilaments, webbings, carbon fibers, prepregs, polyamide fibers, high-performance fibers, non-woven tapes, safety tapes, etc. Its second-generation automatic reel-changing winding machine has the functions of automatic winding, automatic yarn breaking, and automatic switching. It is mainly used for the winding of aramid, carbon fibers, and polyamide fibers. It can also be used for the winding of artificial grass fibers. However, the grass fiber reels after full winding need to be removed manually, and the empty tubes need to be loaded manually. The grass fibers are cut by installing the blade on the knife bar, and the guide rod drives the blade to pull the grass fibers and cut them. The grass fibers are not neatly broken and the quality of the broken ends is poor. Especially when it is used to cut grass fibers with larger grams, it is not possible to cut them all at once, and the cutting rate is low. In addition, its equipment is produced in Germany. After being imported into China, the price of a single machine is very high, and the cost of later use and maintenance is also high.

[0006] The fully automatic precision cross-winding machine produced by Germany's Barmag company has automatic barrel changing without deceleration and a visual program operation terminal. It is mainly used for chemical fiber yarn, webbing, carbon fiber, prepreg tape, polyamide fiber and high-performance fiber in the textile industry. It can also be used for winding artificial turf yarn. However, it also has problems such as manual removal of the grass yarn roll after it is fully rolled, and manual loading of empty tubes. It also has problems such as low cutting rate of heavy grass yarn, high price of single machine, and high cost of use and maintenance. It is not suitable for use in the domestic artificial turf industry.

[0007] Therefore, how to provide an artificial turf winding machine that can automatically load empty tubes and automatically change rolls after full rolls, reduce manual labor intensity and have functions such as automatic winding, automatic cutting of grass silk and reserving grass silk tails, so as to realize the entire winding process in the artificial turf production process fully automatically and without any manual participation, is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0008] In view of this, the present invention provides an artificial turf winding machine that can automatically load empty tubes and automatically change rolls after full rolls, reduce manual labor intensity and has the functions of automatic winding, automatic cutting of grass yarns and reserving grass yarn tails, so as to realize the entire winding process in the artificial turf production process fully automatically and completely eliminate the need for manual participation.

[0009] In order to achieve the above object, the present invention adopts the following technical solution:

[0010] A winding machine for artificial turf yarn, comprising

[0011] frame;

[0012] A winding mechanism, wherein the winding mechanism is fixedly mounted on the frame;

[0013] An automatic roll-changing mechanism is arranged on the frame and located obliquely above the reeling mechanism, and a hollow tube for winding grass silk is provided on the automatic roll-changing mechanism, and the outer tube wall of the hollow tube is in rolling contact with the reeling mechanism so that the grass silk on the reeling mechanism is wound onto the hollow tube and rolled into a grass silk roll.

[0014] It can be seen from the above technical solution that, compared with the prior art, the present invention discloses a winding machine for artificial turf yarn. By setting an automatic reel-changing mechanism, the winding machine can automatically load empty tubes and automatically change reels after full rolls. There is no need for manual reel changing, which not only greatly improves the production efficiency and grass yarn winding quality, but also greatly reduces the labor intensity of operators in the grass yarn production process.

[0015] Furthermore, the winding mechanism comprises:

[0016] A mounting seat, the mounting seat is fixedly mounted on the frame, and a wire guide groove roller and a friction roller arranged in parallel are provided on the mounting seat, and the friction roller is in rolling contact with the outer wall of the hollow tube;

[0017] A wire guide ring, wherein the wire guide ring is slidably connected to the mounting seat, and a grass wire guide hole for the grass wire to pass through is arranged on the top of the wire guide ring, and the bottom of the wire guide ring is clamped in the wire guide groove on the wire guide groove roller;

[0018] A mounting plate, the bottom end of which is fixedly mounted on the frame and located below the mounting seat, and the top end of which is provided with a first motor connected to the guide groove roller and a second motor connected to the friction roller.

[0019] The beneficial effect of adopting the above technical scheme is that the grass wire is guided through the grass wire guide hole on the wire guide ring, the first motor drives the wire guide groove roller to rotate, and the wire guide ring slides in the wire guide groove to realize the movement of the wire guide ring on the mounting seat, the second motor drives the friction roller to rotate, and the friction roller drives the hollow tube to rotate to realize the winding of the grass wire on the hollow tube, thereby realizing automatic winding of the grass wire.

[0020] Furthermore, two bearing seats are installed on the frame at intervals, and the automatic roll changing mechanism includes:

[0021] A U-shaped rotating frame, wherein the yarn breaking mechanism and the yarn hooking moving mechanism are both arranged inside the opening of the U-shaped rotating frame;

[0022] A hollow tube disassembly assembly component, wherein the hollow tube disassembly assembly component is arranged on the U-shaped rotating frame and is located at the opening side of the U-shaped rotating frame;

[0023] A supporting shaft, the supporting shaft is arranged away from the hollow tube disassembly assembly, and both ends of the supporting shaft pass through and are rotatably connected to the two side plates of the U-shaped rotating frame, and are respectively fixedly connected to the two bearing seats;

[0025] A pipe delivery assembly is arranged on the frame and is used to deliver the hollow pipe to the opening side position of the U-shaped rotating frame.

[0026] The beneficial effect of adopting the above technical solution is that when the length and diameter of the grass yarn roll reach the set requirements, the winding mechanism stops winding, and the driving end of the driving cylinder presses down the U-shaped rotating frame, so that the hollow tube disassembly assembly moves up to the tube changing position, and the hollow tube disassembly assembly moves to remove the full grass yarn roll, and then the tube delivery assembly moves to deliver the hollow tube to the opening side position of the U-shaped rotating frame, and the hollow tube is automatically installed through the hollow tube disassembly assembly. This process does not require manual participation, has a high degree of automation, can effectively realize the function of automatic roll change after full roll, and can greatly improve the production efficiency of artificial grass yarn and reduce labor intensity.

[0027] Furthermore, the hollow tube disassembly and assembly assembly comprises:

[0028] A clamping cylinder, wherein the clamping cylinder is fixedly mounted on a first side plate at an opening side of the U-shaped rotating frame, and a telescopic end of the clamping cylinder passes through the first side plate and is arranged toward the opening side;

The cut grass wire tail is sucked into the center hole of the hollow turntable under the action of the vacuum suction gun, and then the tube feeding assembly sends the hollow tube between the clamping turntable and the hollow turntable, and the clamping cylinder drives the clamping turntable to extend and cooperate with the hollow turntable, and fixes the two ends of the hollow tube on the clamping turntable and the hollow turntable respectively, so as to realize the installation of the hollow tube, and the hollow tube rotates by rolling contact with the friction tube, so as to realize the winding of the grass wire on the hollow tube again.

[0034] Furthermore, the grass yarn roll ejection assembly comprises:

[0035] An ejector cylinder, which is fixedly mounted on the top of the second side plate and is located directly above the hollow turntable;

[0038] Furthermore, the delivery pipe assembly includes:

[0039] A long strip mounting plate, one side of which is fixedly connected to the top of the rack;

[0043] A turning cylinder is fixedly connected to the cantilever end of the transverse cantilever plate, and the turning end of the turning cylinder is downwardly arranged and connected to a hollow tube bracket.

[0044] The beneficial effect of adopting the above technical scheme is that when the full roll of grass silk is detached from the clamping turntable and the hollow turntable, the cylinder drives the hollow tube bracket to move downward between the clamping turntable and the hollow turntable. After the clamping turntable and the hollow turntable clamp the two ends of the hollow tube, the flipping end of the flipping cylinder flips downward to make the hollow tube bracket detach from the hollow tube, thereby realizing the automatic feeding of the hollow tube.

[0045] Furthermore, it also includes a yarn breaking mechanism, which is arranged on the frame and includes:
