Description

Technical Field

[0001] The utility model relates to the field of crawler pultrusion machines, in particular to a servo drive device for a continuous fiber crawler pultrusion machine. Background Technique

[0002] In the composite material pultrusion forming process, the servo drive device is a key equipment for realizing continuous production, and its transmission accuracy and stability directly affect the mechanical properties and production efficiency of products. Traditional pultrusion machines mostly adopt rigid gear transmission or sprocket drive methods, which have problems such as easy scratching of fiber pre-impregnated materials due to rigid contact in the transmission system and uneven product thickness caused by traction force fluctuations. Especially when processing products with special-shaped cross-sections, conventional guiding devices often cause traction deviation due to the lack of adaptive adjustment functions, resulting in profile distortion or disorder of internal fiber orientation.

[0003] Although there are designs using hydraulic compensation mechanisms in the prior art, they generally have defects such as complex structures, poor multi-cylinder synchronization, and insufficient reset accuracy, making it difficult to achieve dynamic fiber compensation during continuous production. In addition, the rubber belt body of the traditional traction crawler and the drive mechanism mostly adopt a fixed meshing method, which is prone to creep relaxation under long-term alternating loads, resulting in traction force attenuation and positioning inaccuracy. How to construct an integrated drive system with dynamic pressure balance, multi-directional adaptive adjustment, and stable contact transmission has become an important technical bottleneck for improving the continuous production capacity of pultrusion equipment and the qualification rate of products. By changing the traditional drive method, the transmission part can be used to change the transmission of the crawler. Since the transmission chain of the current crawler transmission is long and large in volume, and the output shaft and input shaft of the universal coupling are not synchronized and the rotation speed is uneven, the transmission stability of the crawler pultrusion machine becomes poor. It is necessary to design a servo drive device for a continuous fiber crawler pultrusion machine to solve the drive problem of the crawler pultrusion machine. Content of the Utility Model

The main frame part bears the drive part and the conveying part.

[0025] The main frame part includes a guide plate 2. A guide groove 1 is opened in the middle of the guide plate 2, which is a rectangular groove. Both end faces of the guide plate 2 are fixedly connected with mounting plates 4. A positioning plate 3 is fixedly assembled on the inner side surface of the mounting plate 4, and screws are installed on the positioning plate 3;

[0026] The first driving part includes a hydraulic cylinder 7. The driving parts are symmetrically arranged on both sides of the main frame part. A clamping frame 6 is fixedly sleeved on the outer surface of the hydraulic cylinder 7. A connecting plate 5 is fixedly installed between the clamping frame 6 and the mounting plate 4. A piston rod 8 is installed in the direction of the guide plate 2 on the hydraulic cylinder 7. A top wheel 9 is installed at the end of the piston rod 8. The second driving part includes a first rotating rod 10 and a second rotating rod 12 which are arranged alternately. The first rotating rod 10 and the second rotating rod 12 are movably assembled. A spiral spring 11 is fixedly connected between the inner sides of the first rotating rod 10 and the second rotating rod 12. A fixing plate 14 is installed at the top end of the second rotating rod 12. Moving parts 13 are installed between the first rotating rod 10 and the mounting plate 4 and between the second rotating rod 12 and the fixing plate 14;

[0027] The conveying part includes symmetrically arranged pallet plates 19. Slide plates 20 are symmetrically installed on the front and rear end faces of the pallet plates 19. A support rod 26 is fixedly installed in the middle of the surface of the slide plate 20. A support ring 22 is welded to the top end of the support rod 26. A support shaft 24 is sleeved inside the support ring 22. A torsion spring 23 is installed between the support shaft 24 and the support ring 22. A turntable 21 is fixedly sleeved on the surface of the support shaft 24. A pulling belt 25 is wound between the turntables 21. The pulling belt 25 is made of natural rubber. A rotating shaft 15 is symmetrically sleeved inside each pallet plate 19. Rotating blocks 17 are evenly sleeved on the surface of the rotating shaft 15. A plug 18 is welded on the surface of the rotating block 17. The plug 18 is triangular in structure. Ultra-high molecular weight polyethylene can be selected, which has a small friction coefficient and reduces the frictional loss to the chain. A return spring 16 is installed between the right side part of the surface of the rotating shaft 15 and the pallet plate 19.

[0028] Wherein, both the first rotating rod 10 and the second rotating rod 12 are movably connected to the moving part 13.

[0029] Working principle: There are upper and lower sets of chains in the crawler pultrusion machine. Two such devices are installed in the middle positions of the upper and lower sets of chains without affecting the mutual cooperation between the upper and lower sets of chains. When conveying the chains, by controlling the hydraulic cylinder 7, the hydraulic cylinder 7 reciprocates, and the top wheel 9 is used to push the first rotating rod 10. At this time, the support plate 19 will be pushed. The insertion block 18 on the support plate 19 will push the chains of the crawler pultrusion machine. When pushing over a long distance, it is more stable and not affected by the coupling. And the insertion block 18 can only rotate unidirectionally. So when the insertion block 18 moves forward, it provides a thrust to the chains. When the insertion block 18 moves backward, the insertion block 18 will stop pushing the chains. The two sets of support plates 19 arranged staggeredly on the left and right sides complete the stable conveyance of the chains. And through the setting of the pulling belt 25, when the support plates 19 on the left and right sides move staggeredly, the friction will be increased and it is easier to apply force. And the pulling belt 25 has the characteristic of wear resistance. This device changes the conveying mode of the chains in the crawler pultrusion machine.

The scope of the present invention is defined by the appended claims and their equivalents.
