[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 As shown;

[0027] A crack-proof bamboo strip bending and shaping device comprises a support 1 and a bending component 4 arranged on the top of the support 1 through a U-shaped bracket 3.

[0028] In this embodiment: In order to solve the technical problems existing in the prior art, as disclosed in the background technology above, "the current bamboo strip bending device, when bending the bamboo strips, often sets a pair of support seats at the bottom of the bamboo strips to facilitate the bamboo strip bending operation. Since the support seats are fixed, they can only perform a single arc bending operation and have poor flexibility." Combined with actual use, this problem is obviously a real problem that is difficult to solve. Therefore, in order to solve this technical problem, a span adjustment component 2 is added on this basis.

[0029] like Figure 1-4 As shown in the figure;

[0030] In combination with the above, for the flexibility of the device, it also includes a span adjustment component 2 arranged at the top center of the support 1;

[0031] The span adjustment assembly 2 comprises a U-shaped support 21 fixed on the top of the support 1 , a screw rod 22 and a pair of slide rods 23 for guiding are arranged between the left and right ends of the U-shaped support 21 through bearings.

[0032] In an optional embodiment, a reduction motor is installed on the U-shaped support 21, and the rotor of the reduction motor is fixedly connected to the screw rod 22. The thread directions at the left and right ends of the screw rod 22 are opposite. The threads in different directions at the left and right ends of the screw rod 22 are respectively screwed with a left threaded sleeve 24 and a right threaded sleeve 25. The left and right ends of the sliding rod 23 are respectively sleeved with a left slide cylinder 26 and a right slide cylinder 27 that slide left and right. A left supporting mechanism 28 is fixed on the left threaded sleeve 24 and the left slide cylinder 26, and a right supporting mechanism 29 is fixed on the right threaded sleeve 25 and the right slide cylinder 27.

[0033] In this embodiment: the driving reduction motor drives the screw rod 22 to rotate. Since the threads on the left and right ends of the screw rod 22 are in opposite directions, the left threaded sleeve 24 and the right threaded sleeve 25 are respectively screwed on the threads in different directions on the left and right ends of the screw rod 22, and the left threaded sleeve 24 and the left slide cylinder 26 are limited by the left support mechanism 28, and the right threaded sleeve 25 and the right slide cylinder 27 are limited by the right support mechanism 29. At this time, the rotation of the screw rod 22 drives the left support mechanism 28 and the right support mechanism 29 to move in opposite directions.

[0034] In an optional embodiment, the left support mechanism 28 and the right support mechanism 29 have the same structural size and are symmetrically arranged on the left and right sides. The left support mechanism 28 includes an L-shaped support 281 fixed on the left threaded sleeve 24 and the left slide cylinder 26. The L-shaped support 281 is provided with a notch 282, and the notch 282 of the L-shaped support 281 is provided with a movable limiting guide wheel 283.

[0035] In this embodiment, the left supporting mechanism 28 and the right supporting mechanism 29 support the bamboo strip. When the bamboo strip is pressed down, the two ends of the bamboo strip slide on the two limiting guide wheels 283.

[0036] In an optional embodiment, the bending assembly 4 includes a cylinder 41 fixed on the U-shaped bracket 3, and a pair of sliding holes 42 opened on the U-shaped bracket 3, a guide rod 43 is arranged inside the sliding hole 42, and a fixing plate 44 is arranged at the bottom of the two guide rods 43, the bottom of the piston rod of the cylinder 41 is fixedly connected to the top center of the fixing plate 44, and an arc-shaped pressure head 45 is fixed at the bottom of the fixing plate 44.

[0037] In this embodiment, the cylinder 41 pushes the fixed plate 44 to move downward, and the fixed plate 44 drives the guide rod 43 to slide inside the sliding hole 42 for guidance, and the fixed plate 44 drives the arc-shaped pressing head 45 to perform a bending operation on the bamboo strips.

[0038] Working principle of this utility model:

[0039] The bamboo strips are supported by the left supporting mechanism 28 and the right supporting mechanism 29, the cylinder 41 pushes the fixed plate 44 to move downward, the fixed plate 44 drives the guide rod 43 to slide inside the sliding hole 42 for guiding, the fixed plate 44 drives the arc pressure head 45 to bend the bamboo strips, and the reduction motor is driven to drive the screw rod 22 to rotate. Since the threads at the left and right ends of the screw rod 22 are in opposite directions, the left threaded sleeve 24 and the right threaded sleeve 25 are respectively screwed on the threads in different directions at the left and right ends of the screw rod 22, and the left threaded sleeve 24 and the left slide cylinder 26 are limited by the left supporting mechanism 28, and the right threaded sleeve 25 and the right slide cylinder 27 are limited by the right supporting mechanism 29. At this time, the rotation of the screw rod 22 drives the left supporting mechanism 28 and the right supporting mechanism 29 to move in opposite directions, adjusting the distance between the two supporting points at the bottom of the bamboo strip, facilitating the bending operation of bamboo strips with different curvatures, and improving the flexibility of the entire device.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
