[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0027] An embodiment of the utility model provides a plastic imitation rattan bending and shaping device.

[0028] As Figure 1 shown, it includes a frame 1 and an imitation rattan tube 2. A clamping seat 3, a driving mechanism, a heating mechanism and a bending mechanism are further provided. The imitation rattan tube 2 sequentially passes through the clamping seat 3, the driving mechanism, the heating mechanism and the bending mechanism. The clamping seat 3 supports and limits the imitation rattan tube 2, and the driving mechanism guides and pushes the imitation rattan tube 2 to slide horizontally.

[0029] Two groups of the heating mechanisms are symmetrically arranged on the left and right sides of the frame 1. The heating mechanism includes a heating seat 4, a horizontal cylinder 5 and a heating block 6. The heating seat 4 is fixed on the frame 1, the horizontal cylinder 5 is fixed on the heating seat 4, the heating block 6 is connected to the cylinder arm of the horizontal cylinder 5, and the heating blocks 6 are symmetrically arranged on both sides of the outer wall of the imitation rattan tube. The heating mechanism can soften the imitation rattan tube 2 in advance.

[0030] As Figure 2 、 3As shown in FIGS. 4 and 5, the bending mechanism includes a bending motor 7, a linkage shaft 8, a bending frame 9, a fixed guide wheel 10, a bending wheel 11, a connecting frame 12 and a support rod 13. The bending motor 7 is fixed on the frame 1. The linkage shaft 8 is connected to the output end of the bending motor 7. The bending frame 9 is fixedly connected to the linkage shaft 8. The bending frame 9 includes a horizontal portion and a vertical portion that are perpendicular to each other in an L shape. The linkage shaft 8 is fixedly connected to the horizontal portion. The fixed guide wheel 10 is rotatably connected to the linkage shaft 8. The outer edges of the fixed guide wheel 10 and the bending wheel 11 are provided with bending grooves. The side wall of the bending groove is arc-shaped and is in concave-convex fit with the outer wall of the imitation rattan tube 2. The imitation rattan tube 2 passes through the gap between the fixed guide wheel 10 and the bending wheel 11. The bending wheel 11 is rotatably connected to one end of the horizontal portion away from the linkage shaft 8. The horizontal portion is perpendicular to the central axis of the imitation rattan tube 2. The vertical portion is fixed with a bending slide rod 14. The connecting frame 12 is slidably connected to the bending slide rod 14. The connecting frame 12 is provided with a threaded hole and a horizontal chute that are perpendicular to each other and communicate with each other. The support rod 13 is fixedly connected to the connecting frame 12 and extends axially toward the imitation rattan tube. The support rod 13 is inserted into the imitation rattan tube. The connecting frame 12 is provided with a locking mechanism. The locking mechanism includes a locking bolt 15 threadedly connected to the connecting frame 12, a locking slider 16 slidably connected to the connecting frame 12, and a return spring 17 connected between the connecting frame 12 and the locking slider 16. The locking bolt 15 is threadedly connected in the threaded hole. The locking slider 16 is horizontally slidably connected in the horizontal chute. One side of the locking slider 16 facing the locking bolt 15 is provided with a pressing inclined surface. The lower end of the locking bolt 15 abuts against the pressing inclined surface. The end of the locking slider 16 abuts against the bending frame 9. The connecting frame 12 is slidably connected to the bending slide rod 14. One side of the bending slide rod 14 facing the locking slider 16 is provided with a locking groove. The locking slider 16 abuts and is clamped in the locking groove. By rotating the locking bolt 15 through threaded cooperation, the locking bolt 15 can move downward and abut against the pressing inclined surface. Through the sliding of the inclined surface, the locking slider 16 slides horizontally outward and abuts and is clamped in the locking groove to form positioning, avoiding the horizontal sliding or rotation of the connecting frame 12 on the bending slide rod 14.

[0031] A positioning sleeve 18 is sleeved on the bending slide rod 14. The bending frame 9 and the connecting frame 12 abut against both ends of the positioning sleeve 18. The front end of the support rod 13 extends to the middle position of the gap between the fixed guide wheel 10 and the bending wheel 11. The positioning sleeve 18 plays a positioning role, enabling the front end of the support rod 13 to just extend to the middle position of the gap between the fixed guide wheel 10 and the bending wheel 11 when the connecting frame 12 slides to abut against the positioning sleeve 18, that is, to extend to the position where the imitation rattan tube 2 is pressed and bent.

[0032] The front end of the support rod 13 is provided as a threaded rod. A limit screw piece 19 is threadedly connected to the front end of the support rod 13. The limit screw piece 19 abuts against the end of the rattan-like tube. The limit screw piece 19 can horizontally adjust its position on the threaded rod to limit the rattan-like tube 2, that is, the distance between the bent part and the end of the rattan-like tube 2.

[0033] As Figure 1 , 6 shown, the driving mechanism includes two sets of symmetrically arranged driving seats 20, driving wheels 21 and a balance assembly. The driving seats 20 are slidably connected to the frame 1. The driving wheels 21 are rotatably connected to the driving seats 20. The balance assembly is connected between the two sets of symmetrically arranged driving seats 20. A driving motor 22 is fixed on one of the driving seats 20. The driving wheel 21 is connected to the output end of the driving motor 22. The balance assembly includes a balance cylinder 23, a piston rod 24 and a balance spring 25. The balance cylinder 23 and the balance rod are respectively connected to the driving seats 20 on both sides. The balance spring 25 is connected between the balance cylinder 23 and the balance rod. An adjusting plate is fixed on the frame 1. An adjusting screw is threadedly connected to the adjusting plate. The front end of the adjusting screw is rotatably connected to the driving seat 20. The adjusting screw can move left and right on the adjusting plate, thereby adjusting the driving seat 20 to move towards the rattan-like tube 2 and abut against the outer wall of the rattan-like tube. The setting of the balance cylinder 23 assembly makes the pressures on both sides of the rattan-like tube 2 of the two driving seats 20 consistent.

[0034] Working principle:

[0035] In the present utility model, the rattan-like tube 2 sequentially passes through the clamping seat 3, the driving mechanism, the heating mechanism and the bending mechanism. By adjusting the screw, the driving seat 20 slides towards the rattan-like tube 2 until the driving wheel 21 abuts against the outer wall of the rattan-like tube. By rotating the driving motor 22, the rattan-like tube 2 can be driven to slide horizontally along the axis through the friction between the driving wheel 21 and the rattan-like tube 2. After the heating block 6 heats the rattan-like tube, the driving motor 22 can drive the heated and softened rattan-like tube 2 to the bending mechanism position;

[0036] Since the horizontal part of the bending frame 9 is connected between the fixed guide wheel 10 and the bending wheel 11, the horizontal part is perpendicular to the central axis of the rattan-like tube. The bending slide rod 14 is connected to the vertical part perpendicular to the horizontal part, that is, the bending slide rod 14 is parallel to the central axis of the rattan-like tube 2. At the same time, the support rod 13 makes the central axis of the support rod 13 coincide with the central axis of the rattan-like tube through the connecting frame 12. The support rod 13 can be smoothly inserted into the interior of the rattan-like tube 2 to form an internal support. The fixed guide wheel 10 and the bending wheel 11 form a bending extrusion force on the outer wall of the rattan-like tube 2, so that the rattan-like tube 2 will not have an internal concave during the bending process;

[0037] After the bending is completed, the locking bolt 15 can be rotated upward. Under the action of the return spring 17, the locking slider 16 slides horizontally inward, unlocking the connecting frame 12 from the bending slide rod. Then, the connecting frame 12 can be slid backward to disengage the support rod 13 from the end of the artificial rattan tube 2. After that, the connecting frame 12 is rotated to turn the support rod 13 away from the position of the artificial rattan tube 2, which can facilitate the horizontal driving of the bent artificial rattan tube 2 out of the bending and shaping device and facilitate the removal of the artificial rattan tube 2.

[0038] Furthermore, the left - right position of the limit screw piece 19 on the threaded rod can be adjusted. The limit screw piece 19 abuts against the end of the artificial rattan tube, and the distance between the bending position of the artificial rattan tube 2 and the end of the artificial rattan tube 2 can be adjusted.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
