Description

Technical Field

[0001] The invention relates to the technical field of glass fiber chopped short, and in particular to a glass fiber chopped short linked swing mechanism. Background Art

[0002] Chopped strand mat is made of glass fiber, which is used as the reinforcing material of FRP composite materials and is suitable for various molding processes such as hand lay-up and continuous board making. The production of chopped strand mat requires the glass fiber raw yarn to be cut by a shredder and then evenly distributed on the mesh belt. Therefore, the glass fiber needs to be swung during the chopped process so that the chopped glass fiber can be more evenly dispersed on the mesh belt.

[0003] In order to make the glass fiber precursor more evenly distributed in the chopped width range, a wobbler structure was invented. The wobbler swings the yarn to make the glass fiber precursor swing within the chopped width range, making it easier to cut. At the same time, it avoids the phenomenon of frequent local cutting of the rubber roller by the cutter, causing excessive wear of the local area. However, in the actual production process of chopped strands, multiple shredders are required to be distributed in an array on the same plane, which requires multiple wobblers to be distributed in an array to cooperate with the shredders for chopped strands. Since the wobbler needs to be driven by a reduction motor, there are many devices on the entire working plane, the cost investment is too high, and the layout is unreasonable, which affects the process operation. There will also be problems such as oil leakage from the reduction motor dripping onto the felt surface, polluting the chopped strands surface. Summary of the invention

[0029] like Figure 1-4As shown, the embodiment of the present application discloses a glass fiber short-cut linkage swing mechanism, including a workbench 10, a swinger 20, a lateral swing rod 30 and a linkage drive mechanism 40. The workbench 10 is arranged above the short-cut machine, and a plurality of swingers 20 are arranged thereon, and the number of swingers 20 is consistent with the number of short-cut machines and corresponds one to one. The plurality of swingers 20 are arranged in an array on the workbench 10 into a plurality of rows and a plurality of columns, and the center line of each row of swingers 20 is arranged at an angle to the length direction of the workbench 10, and the center line of each column of swingers 20 is parallel to the width direction of the workbench 10, so that the yarns of each row can be prevented from being led to the swinger 20 along the same path, thereby effectively reducing the probability of mutual interference between the yarns, and making the overall layout more reasonable. A through hole 11 for the yarn to pass through is opened on the workbench 10 corresponding to each swinger 20, and the yarn passes through the swinger 20 and enters the short-cut machine downward from the through hole 11. The transverse swing arm 30 corresponds to the swing device 20, one is provided in each row, and is connected to the swing device 20 through a U-shaped fixing seat 31 and a connecting rod 32. One transverse swing arm 30 controls the swing of a row of swing devices 20. The linkage driving mechanism 40 is used to control the synchronous rotation of the transverse swing arms 30 used.

[0030] Specifically, the rocker 20 includes a mounting base 21 disposed on the workbench 10, a swing arm 22 is rotatably disposed on the mounting base 21 through a rotating shaft 28, a connecting arm 23 is disposed on the swing arm 22, two fixed plates 24 are arranged at intervals on the connecting arm 23, a connecting shaft 25 is disposed between the two fixed plates 24, a plurality of yarn guide wheels 26 are rotatably disposed on the connecting shaft 25, a yarn separation grate 27 is further disposed between the two fixed plates 24 on the yarn feeding side of the yarn guide wheel 26, a plurality of yarn separation teeth are disposed on the yarn separation grate 27, and the yarn separation teeth are arranged corresponding to the yarn guide wheel 26. When arranged, the axis core of the rotating shaft 28 is parallel to the length direction of the lateral rocking arm 30, and the length direction of the connecting shaft 25 is perpendicular to the length direction of the rotating shaft 28. The cross-section of the swing arm 22 is convex as a whole, and a C-shaped groove is correspondingly provided on the connecting arm 23, so that the C-shaped groove of the connecting arm 23 can be inserted into the swing arm 22 to realize the connection between the connecting arm 23 and the swing arm 22, so that a detachable connection with a quick-release structure is formed between the connecting arm 23 and the swing arm 22, which is convenient for replacement of the yarn guide wheel 26 and the yarn dividing grate 27 after they are worn.

The motor seat 441 is disposed beside the workbench 10 and away from the working area of ​​the workbench 10, so as to avoid the problem of motor oil leakage and contamination of the chopped strand mat surface. A reduction motor 442 is disposed on the motor seat 441. A rotating sleeve 443 is fixedly disposed on the output shaft of the reduction motor 442. An eccentric shaft 444 is eccentrically disposed on the end face of the rotating sleeve 443. A first transmission rod 445 is rotatably disposed on the eccentric shaft 444. A second transmission rod 446 is rotatably disposed on the end of the first transmission rod 445 away from the eccentric shaft 444. The second transmission rod 446 is a Y-shaped rod. The Y-shaped end of the second transmission rod 446 is connected to the first transmission rod 445 by an axis hinge. A hole is disposed on the end of the second transmission rod 446 away from the first transmission rod 445. The hole is sleeved on the transverse rocking arm 30 so that the second transmission rod 446 is rotatably connected to the transverse rocking arm 30. The reduction motor 442 drives the rotating sleeve 443 to rotate, and under the action of the eccentric shaft 444, the first transmission rod 445 and the second transmission rod 446 drive the transverse swing arm 30 to reciprocate, thereby converting the periodic continuous rotation of the reduction motor 442 into a small rotation of the transverse swing arm 30.

[0035] The operating principle of a glass fiber short-cut linkage swing mechanism in this embodiment is: the reduction motor 442 drives one of the lateral swing arms 30 to rotate slightly, and under the action of the connecting rod 43 and the vertical rod 41, all the lateral swing arms 30 are driven to rotate slightly synchronously, and then under the action of the U-shaped fixed seat 31 and the connecting rod 32, all the swingers 20 are driven to swing back and forth synchronously, thereby realizing the synchronous linkage of all the swingers 20.
