Description

Technical Field

[0001] The invention relates to a single-sided double-knife roller automatic quick-change online high-speed glass fiber chopping machine, which is used for processing glass fibers. Background Art

[0002] At present, most fiber cutting machines are off-line short-cut machines, but the off-line short-cut process is long, the labor productivity is low, and the energy consumption is high. The online short-cut machine directly cuts the glass fiber coming out of the leaking plate, which has a short process flow, energy saving and high efficiency.

[0003] Traditional online short-cutting machines only have a pair of knife rollers and rubber rollers. When the knife rollers and rubber rollers are damaged or exhausted, they can only be stopped for replacement, and continuous short-cutting cannot be achieved. During the replacement of the knife rollers and rubber rollers, a large amount of glass fibers cannot be drawn or short-cut, thus becoming waste. Therefore, traditional online short-cutting machines have problems such as inability to produce continuously, serious waste and pollution, and unstable quality, which seriously affect the promotion, application and development of online short-cutting machines.

[0004] The improved online short-cutting machine is equipped with two sets of knife rollers and rubber rollers, which are arranged on both sides of the equipment (180° relative). When the knife rollers and rubber rollers on the working side are damaged and need to be replaced, the machine must be stopped, the yarn must be cut, and after the reversal, the yarn must be manually re-introduced and loaded for short-cutting. Although this equipment reduces the time for online replacement of knife rollers and rubber rollers, it cannot achieve continuous production, and there is also a waste of production capacity and low efficiency. Summary of the invention

[0005] In order to overcome the defects of the prior art, the present invention provides a high-speed glass fiber short-cutting machine with a reasonable structure, stable quality of short-cut finished products, continuous production, and automatic quick change of knife rollers and rubber rollers without stopping the machine or breaking the wire. The technical solution of the present invention is:

The working knife roller is adjacent to the working rubber roller; the spare knife roller is adjacent to the spare rubber roller; the knife roller driving device is connected to a power control unit, and the rubber roller swinging cylinder is connected to a pneumatic control unit.

[0008] The automatic switching mechanism includes a turntable bearing, a turntable and a flip spindle. A turntable is installed at one end of the flip spindle. The turntable is rotatably installed on the machine body through the turntable bearing. The other end of the flip spindle is rotatably installed on the flip spindle fixing seat. The flip spindle is driven by a flip driving mechanism.

[0009] The flip transmission mechanism comprises a flip belt, a flip motor and a flip pulley. A flip pulley is installed on one end of the flip main shaft and on the motor shaft of the flip motor. The two flip pulleys are connected through a flip belt transmission.

[0011] The wire pushing mechanism comprises a wire pushing rod, a wire pushing cylinder and a wire pushing plate. One end of the wire pushing rod is hinged to the piston rod of the wire pushing cylinder, and the other end is provided with a wire pushing plate, which reciprocates between the wire winding ring on the working rubber roller and the wire winding ring on the standby rubber roller.

[0012] The advantages of the present invention are: an online grinding mechanism is configured to perform online repair of slightly damaged rubber rollers, which is convenient and quick; when the working knife rollers and rubber rollers are seriously damaged and need to be replaced, the glass fiber being chopped is guided to another pair of spare knife rollers and rubber rollers through the configured automatic switching mechanism and wire pushing mechanism, and the two sets of knife rollers and rubber rollers can be automatically and quickly replaced without stopping the machine or yarn, thus ensuring the continuity of chopped production. The output of finished glass fiber chopped products and the stability of product quality are improved, the discharge of waste glass fiber is reduced, and the pollution to the environment caused by glass fiber chopped production is reduced.

[0026] The automatic switching mechanism 3 includes a turntable bearing 3-1, a turntable 3-2 and a flip spindle 3-4. The turntable 3-2 is installed at one end of the flip spindle 3-4, and the turntable 3-2 is rotatably installed on the machine body 1 through the turntable bearing 3-1. The other end of the flip spindle 3-4 is rotatably installed on the flip spindle fixing seat 3-3, and the flip spindle 3-3 is driven by the flip driving mechanism 3-5.

[0027] The flip transmission mechanism 3-5 includes a flip belt 3-5-1, a flip motor 3-5-2 and a flip pulley 3-5-3. A flip pulley 3-5-3 is installed on one end of the flip main shaft 3-3 and the motor shaft of the flip motor 3-5-2. The two flip pulleys 3-5-3 are connected by the flip belt 3-5-1.

[0028] The online grinding mechanism 5 includes a grinding wheel 5-1, a belt transmission mechanism 5-2, a grinding motor 5-3 and a grinding swing cylinder 5-4. The grinding motor 5-3 is installed on a motor mounting plate, which is driven by the grinding swing cylinder 5-4 and rotatably installed on the machine body 1; the grinding motor 5-3 is installed with a grinding wheel mounting plate through a belt transmission mechanism 5-2, and the grinding wheel 5-1 is rotatably installed on the grinding wheel mounting plate.

[0029] The wire pushing mechanism 15 includes a wire pushing rod 15-1, a wire pushing cylinder 15-2 and a wire pushing plate 15-3. One end of the wire pushing rod 15-1 is hinged to the piston rod of the wire pushing cylinder 15-1, and the other end is equipped with a wire pushing plate 15-3. The wire pushing plate 15-3 reciprocates between the wire winding ring on the working rubber roller and the wire winding ring on the spare rubber roller.

[0030] The working principle of the present invention is:

[0031] During normal short cutting, the working rubber roller 2-2 presses the working knife roller 2-1, and the working knife roller 2-1 rotates at high speed and drives the working rubber roller 2-2 to rotate to cut the glass fiber. The spare knife roller 2-3 and spare rubber roller 2-4 do not move.

[0032] When the working knife roller 2-1 and the working rubber roller 2-2 are seriously damaged and cannot work, it is necessary to swap the spare knife roller 2-3 and the spare rubber roller 2-4. At this time, the online grinding mechanism 5 is spaced away from the working rubber roller 2-2, and the wire pushing mechanism pushes the yarn from the working rubber roller 2-2 to the wire winding ring 2-7 at the end of the working rubber roller, and winds it in the waste wire groove of the wire winding ring 2-7. Then the turntable starts to automatically switch counterclockwise, and the yarn rotates with the wire winding ring on the working rubber roller 2-2. When the working rubber roller 2-2 rotates to a preset angle, the yarn enters the wire winding ring groove on the spare rubber roller 2-4. The two wire winding rings rotate through the speed difference to cut off the yarn, completing the switching of the yarn between the working rubber roller 2-2 and the spare rubber roller 2-4, and then the yarn is pushed back to the spare rubber roller by the wire winding ring. During the automatic switching process, the glass fiber bundle on the wire winding ring 2-7 at the front end of the working rubber roller 2-2 begins to contact the wire winding ring 2-7 at the front end of the spare rubber roller 2-4. Along with conversion into place, the glass fiber bundle is completely wound on the front end wire winding ring 2-7 of the standby rubber roller 2-4. The wire pushing mechanism pushes the glass fiber bundle back on the standby rubber roller 2-4 subsequently.

[0033] After the spare knife roller 2-3 and spare rubber roller 2-4 are swapped, the short-cut production is continued. At this time, the maintenance personnel can replace the damaged working knife roller 2-1 and working rubber roller 2-2 as spare parts, and the cycle continues.
