[0025] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0026] As Figures 1 - 5 shown, a bending device for bamboo product processing includes a support plate 1. Four support legs 2 are fixedly and distributively connected to the bottom of the support plate 1. A vertical plate 3 is fixedly connected to the top of the support plate 1. A hydraulic cylinder 1 is fixedly connected to the side of the vertical plate 3. The output end of the hydraulic cylinder 1 is fixedly connected to the side of the limit block 5. The hydraulic cylinder 1 is used to drive the limit block 5 to move. It also includes a bending structure and a heating structure;

[0027] The bending structure is fixedly connected to one end of the top of the support plate 1 away from the limit block 5. The bending structure includes a fixing plate 6, a bending plate 7 and a driving structure. The fixing plate 6 is fixedly connected to the top of the support plate 1 and is aligned with the limit block 5. When the hydraulic cylinder 1 is started, the limit block 5 is moved towards the fixing plate 6, so that the limit block 5 and the fixing plate 6 can squeeze and fix the bamboo strip. There are two bending plates 7. The two bending plates 7 are symmetrically located at the left and right ends of the fixing plate 6 respectively for bending the bamboo strip. An inverted L-shaped reinforcing rod 23 is provided at the top of 1. One end of the bending plate 7 close to the fixing plate 6 is rotatably connected between the reinforcing rod 23 and the support plate 1. There are two sets of driving structures for driving the corresponding bending plates 7 to rotate. The driving structures are arranged between the support plate 1 and the corresponding bending plates 7;

[0028] There are two sets of heating structures, and both are rotatably connected to the top of the support plate 1. The heating structures are located between the corresponding bending plates 7 and the fixing plate 6 for heating the bending part.

[0029] In some specific implementation schemes, such as Figure 2 or Figure 3As shown in the figure, in order to facilitate driving the bending plate 7 to bend the bamboo strips, each set of driving structures includes a moving column 8, an arc-shaped guide groove 9 and an inclined guide rail 11. The moving column 8 is vertically and fixedly connected to one end of the bending plate 7 away from the fixed plate 6. The arc-shaped guide groove 9 is penetrated and opened at the top of the support plate 1. The moving column 8 is slidably connected inside the arc-shaped guide groove 9 and penetrates to the bottom of the arc-shaped guide groove 9. The inclined guide rail 11 is slidably connected to the corresponding moving column 8. A moving block 12 is symmetrically connected between the two inclined guide rails 11. A second hydraulic cylinder 13 is fixed to the bottom of the support plate 1. The driving end of the second hydraulic cylinder 13 is connected to the moving block 12. A T-shaped block 14 is fixedly connected to one end of the moving block 12 close to the support plate 1. The T-shaped block 14 is slidably connected to the bottom of the support plate 1. When the second hydraulic cylinder 13 extends, it synchronously drives the moving block 12 and the inclined guide rail 11 to move. The inclined guide rail 11 squeezes the moving column 8 to slide along the arc-shaped guide groove 9, so that the bending plate 7 rotates to bend the bamboo strips.

[0030] In some specific embodiments, such as Figure 2 As shown in the figure, in order to heat the bending part of the bamboo strips, each set of heating structures includes a shunt bin 15 and a flexible conduit 17. A rotating shaft is fixedly connected to the bottom of the shunt bin 15. The shunt bin 15 is rotatably connected to the top of the support plate 1 through the rotating shaft. A number of water vapor spray nozzles 16 are fixedly arranged on one side of the shunt bin 15 close to the limit block 5. One end of the flexible conduit 17 is communicated with the shunt bin 15, and the other end is fixedly connected to a water pump 18. One end of the water pump 18 away from the flexible conduit 17 is fixedly connected to a hot water tank 19. The rotating shaft penetrates the support plate 1, and a rotating structure is arranged at the bottom of the rotating shaft. The rotating structure is cooperatively connected with the inclined guide rail 11.

[0031] The bending plate 7 is used to extrude and bend the required bending part of the material. At the same time, the water pump 18 is turned on. The hot water in the hot water tank 19 is pumped to the shunt bin 15 through the water pump 18, and water vapor is sprayed through the water vapor spray nozzles 16. The water vapor spray nozzles 16 are used to make the water vapor spray onto the material at the bending part for heating and wetting, so as to avoid the material from breaking when being bent, and at the same time, the generation of debris can be reduced, the integrity of the material can be maintained, and the product quality can be improved.

[0032] In some specific embodiments, such as Figure 3 As shown in the figure, in order to enable the shunt bin 15 to always be aligned with the bending part of the bamboo strips, the rotating structure includes a gear 20 and a rack 21. There are two gears 20 and two racks 21. The gear 20 is connected to the bottom of the corresponding rotating shaft, and the racks 21 are respectively connected to the bottoms of the corresponding inclined guide rails 11. The gear 20 is meshed with the rack 21. During the movement of the inclined guide rail 11, the rack 21 is driven to move, and the engaged gear 20 also rotates accordingly. The gear 20 and the shunt bin 15 are fixedly connected through the rotating shaft, so that the shunt bin 15 rotates towards the bending part of the bamboo strips, and the water vapor spray nozzles 16 can always be aligned with the bending part of the bamboo strips.

[0033] In some specific embodiments, such asFigure 4 As shown, in order to prevent the bending plate 7 from tilting when bending the bamboo strips, the moving column 8 includes a convex block 10 fixed on its outer side, and the convex block 10 is slidably connected to the arc-shaped guide groove 9, increasing the contact area and improving the stability of the rotation of the bending plate 7.

[0034] In some specific implementation embodiments, such as Figure 1 As shown, in order to prevent the bending plate 7 from scratching the surface of the bamboo strips, a rubber pad 22 is connected to one side of each bending plate 7 close to the limit block 5.

[0035] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0036] During actual use, place the bamboo strips on one side of the fixing plate 6 close to the limit block 5, start the first hydraulic cylinder 4, move the limit block 5 towards the fixing plate 6 until the limit block 5 presses and fixes the bamboo strips against the fixing plate 6. Then extend the second hydraulic cylinder 13. The second hydraulic cylinder 13 drives the moving block 12 to move horizontally synchronously with the inclined guide rail 11. Under the action of the inclined guide rail 11, the two moving columns 8 move towards the middle inside the inclined guide rail 11, so that the moving columns 8 move along the arc-shaped guide groove 9. During the sliding process of the moving columns 8, the bending plates 7 are driven to rotate. The bending plates 7 on both sides squeeze the bamboo strips towards the side end of the limit block 5. By changing the connection method of the bending plates 7, it is possible to prevent the bending plate from damaging or breaking the side of the bamboo strips. Moreover, rubber pads 22 are fixed on the bending plates 7, which can prevent scratching the surface of the bamboo strips. At the same time, turn on the water pump 18, pump the hot water in the hot water tank 19 to the shunt bin 15 through the water pump 18, and spray water vapor through the water vapor nozzles 16. Use the water vapor nozzles 16 to make the water vapor spray onto the material at the bending part for heating and wetting. During the movement of the second hydraulic cylinder 13, the inclined guide rail 11 can drive the rack 21 to move, and the engaged gear 20 drives the shunt bin 15 to rotate. Thus, during the process of the bending plate 7 bending the bamboo strips, the shunt bin 15 gradually rotates towards the bending part of the bamboo strips, so as to realize that the shunt bin 15 can always heat the bending part and avoid breakage during the bending process.

[0037] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
