Abstract
Description
Technical Field
[0001] This utility model belongs to the field of solid wood bending processing technology, specifically, it relates to a bending and forming device for curved solid wood. Background Technology
[0002] When processing furniture and other products, solid wood boards need to be treated first. Some solid wood boards need to be humidified and heated before being placed on a bending and deformation device to bend the solid wood boards, thereby obtaining curved wood materials, which are convenient for subsequent assembly into products.
[0003] The utility model patent with application number CN201921177859.4 (publication number CN210589774U) discloses a wood bending machine, which includes a wood softening component, a pushing component and a wood bending component. The wood softening component includes a steaming cabinet and a steam conveying component. The steam conveying component includes an upper steam conveying component and a lower steam conveying component.
[0004] Because the steamed solid wood boards have a certain temperature and a certain weight, it is not convenient to manually place them on the bending point. The above-mentioned patent requires the steamed solid wood boards to be moved to the bending component for bending and shaping. There is still a certain distance between the roller and the nearest installation roller. However, in the actual processing, the boards have different lengths and widths. The above-mentioned board moving method may make it impossible to move the boards smoothly onto the two installation rollers, resulting in them falling off. Utility Model Content
[0005] In view of this, the present invention provides a bending and forming device for curved solid wood, which solves the technical problem that solid wood boards after steaming and boiling have a certain temperature and are not convenient to be manually placed at the bending point.
[0006] This utility model is implemented as follows:
[0007] This utility model provides a bending and forming device for curved solid wood, which has a working box, wherein the working box is provided with a board feeding mechanism and a bending and forming mechanism;
[0008] The plate feeding mechanism includes three horizontally arranged conveyors. The pulleys at the front ends of the three conveyors are fixedly connected to a rotating rod. All of the conveyors are fixedly installed on the lifting plate.
[0009] The bending forming mechanism includes mounting rollers located on the left and right sides of the central conveyor and a bending head located directly above the central conveyor.
[0010] Based on the above technical solution, the bending and forming device for curved solid wood of this utility model can be further improved as follows:
[0011] Furthermore, a bracket A is fixedly installed on the front wall of the work box, and a fixed end of a telescopic cylinder A is fixedly installed on the bottom wall of the top plate of the bracket A. The movable end of the telescopic cylinder A extends upward and its end is fixedly installed in the middle of the bottom wall of the lifting plate.
[0012] Furthermore, upright plates are fixedly installed on both the left and right sides of the conveyor frame, and the bottom wall of the upright plates is fixedly installed on the top wall of the lifting plate.
[0013] Furthermore, a drive motor A is fixedly installed on the right end of the lifting plate, and a transmission wheel is fixedly installed on the output shaft of the drive motor A and the right end of the rotating rod. A conveyor belt is sleeved on both of the transmission wheels.
[0014] Furthermore, both the front and rear ends of the mounting roller are fixedly mounted on the mounting plate, and the bottom wall of the mounting plate is fixedly mounted on the working box;
[0015] A bracket B is fixedly installed at the rear end of the top wall of the work box. A telescopic cylinder B is fixed on the top plate of the bracket B. The movable end of the telescopic cylinder B extends downward and is fixedly connected to the middle of the top wall of the bending head.
[0016] Furthermore, the top wall of the work box, located at the left end of the left conveyor and the right end of the right conveyor, is provided with a horizontally arranged moving groove, and two symmetrically arranged positioning plates are slidably connected in the moving groove;
[0017] A double-ended lead screw is rotatably connected to the inner bottom wall of the working box. Both ends of the double-ended lead screw are fitted with screw blocks that are threadedly connected to it. The positioning plate is fixedly installed on each screw block.
[0018] Compared with the prior art, the beneficial effects of the bending and forming device for curved solid wood provided by this utility model are:
[0019] By setting up a board feeding mechanism, the cooked boards can be moved to the bending and forming area, avoiding the need to manually handle the warm solid wood boards.
[0020] By setting up three vertically moving conveyors, the solid wood boards are transported to the designated position and then moved downwards without affecting the bending and shaping of the solid wood boards;
[0021] By setting both the feeding mechanism and the forming mechanism on the top surface of the work box, the floor space can be reduced. Furthermore, there is no horizontal or vertical spacing between the mounting rollers supporting the solid wood boards and the conveyor that transports the solid wood boards. This prevents excessively short or narrow solid wood boards from failing to move smoothly to the mounting rollers and avoids them falling during the movement. Attached Figure Description

[0034] Example 1
[0035] like Figure 1-4 As shown, this utility model provides a bending and forming device for curved solid wood, which has a working box 1, wherein the working box 1 is provided with a board feeding mechanism and a bending and forming mechanism.
[0036] The sheet material feeding mechanism includes three horizontally arranged conveyors 20. The pulleys 21 at the front end of the three conveyors 20 are all fixedly connected to the rotating rod 22. All the conveyors 20 are fixedly installed on the lifting plate 23.
[0037] The bending forming mechanism includes mounting rollers 31 located on the left and right sides of the central conveyor 20, and a bending head 32 located directly above the central conveyor 20.
[0038] Optionally, in the above technical solution, a bracket A24 is fixedly installed on the front wall of the work box 1, and the fixed end of the telescopic cylinder A25 is fixedly installed on the bottom wall of the top plate of the bracket A24. The movable end of the telescopic cylinder A25 extends upward and the end is fixedly installed in the middle of the bottom wall of the lifting plate 23.
[0039] Optionally, in the above technical solution, upright plates 29 are fixedly installed on both the left and right sides of the frame of the conveyor 20, and the bottom wall of the upright plate 29 is fixedly installed on the top wall of the lifting plate 23.
[0040] Optionally, in the above technical solution, a drive motor A26 is fixedly installed on the right end of the lifting plate 23, and a transmission wheel 27 is fixedly installed on the output shaft of the drive motor A26 and the right end of the rotating rod 22. A conveyor belt 28 is sleeved on both transmission wheels 27.
[0041] Optionally, in the above technical solution, both the front and rear ends of the mounting roller 31 are fixedly mounted on the mounting plate 33, and the bottom wall of the mounting plate 33 is fixedly mounted on the working box 1.
[0042] A bracket B34 is fixedly installed on the rear end of the top wall of the work box 1. A telescopic cylinder B35 is fixed on the top plate of the bracket B34. The movable end of the telescopic cylinder B35 extends downward and is fixedly connected to the middle of the top wall of the bending head 32.
[0043] Optionally, in the above technical solution, the top wall of the work box 1 and the left end of the left conveyor 20 and the right end of the right conveyor 20 are both provided with a horizontally arranged moving groove 11, and two symmetrically arranged positioning plates 4 are slidably connected in the moving groove 11.
[0044] A double-ended lead screw 41 is rotatably connected to the inner bottom wall of the working box 1. Both ends of the double-ended lead screw 41 are fitted with screw blocks 42 that are threadedly connected to it. Positioning plates 4 are fixedly installed on the screw blocks 42.
[0045] The movable end of telescopic cylinder A25 passes through the top plate of bracket A24, and the movable end of telescopic cylinder B35 passes through the top plate of bracket B34. Guide rods are provided on both the left and right sides of telescopic cylinders A25 and B35.
[0046] The rear wall of the work box 1 can be opened to facilitate maintenance and replacement of internal parts.
[0047] Furthermore, the front end of the working box 1 is equipped with a steaming cabinet body 5, which has a board feed port on the left end and a board discharge port on the right end.
[0048] The front end of the cooking cabinet body 5 is provided with a support frame body 6, and a pusher cylinder body 61 is fixedly installed on the support frame body 6. A pusher strip body 62 is fixed on the output end of the pusher cylinder body 61.
[0049] The operation of the pusher cylinder body 61 enables the pusher bar body 62 to move horizontally backward, so that the pusher bar body 62 can come into contact with the side wall of the solid wood board and discharge the solid wood board through the discharge port, so that the solid wood board moves onto the conveyor 20.
[0050] The top surface of the conveyor 20 is on the same plane as the bottom wall of the feed inlet and discharge outlet of the cooking cabinet body 5.
[0051] The installation roller 31 and the bending head 32 have the same longitudinal length. The longitudinal length of the plate to which this device is applicable does not exceed the length of the bending head 32, and the transverse length of the plate does not exceed the length between the two positioning plates 4.
[0052] In the initial state, the movable end of telescopic cylinder A25 is fully extended, the movable end of telescopic cylinder B35 is fully retracted, and the distance between the two positioning plates 4 is at its maximum.
[0053] Among them, the transmission wheel 27 is a toothed wheel, and the transmission belt 28 is a toothed belt adapted to it.
[0054] When the solid wood board moves onto the conveyor 20, the drive motor A26 is started so that it drives the pulley 21 to rotate through the transmission wheel 27 and the conveyor belt 28. This causes the conveyor belts of the three conveyors 20 to simultaneously move the solid wood board backward. When it moves to the appropriate position (the appropriate position means that the back wall of the solid wood board does not exceed the back wall of the pressure bend 32), the positioning plates 4 on both sides retract inward at the same time to move the solid wood board to the middle.
[0055] Then, the movable end of the bracket A24 is fully retracted, causing the lifting plate 23 to move down. Since the left and right sides of each conveyor 20 frame are fixedly installed on the lifting plate 23 by the upright plate 29, the conveyor 20 moves to the lowest end with the lifting plate 23. During the downward movement of the conveyor 20, the solid wood board falls on the two mounting rollers 31.
[0056] At this time, the telescopic cylinder B35 is activated to extend its movable end, which drives the bending head 32 to move down, and in cooperation with the installation roller 31, it bends the solid wood board.
[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
