Description

Technical Field

[0001] This utility model relates to a plywood compaction device, belonging to the field of plywood compaction technology. Background Technology

[0002] Plywood is a type of board made by stacking, gluing, and pressing multiple layers of rotary-cut veneers from trees. To make the plywood stronger and more secure, the number of layers is usually odd. Because the grain of each veneer is different, they can restrain each other, making the solid wood less prone to curling and deformation. After the veneers are glued and stacked, they need to be pressed to form a whole board, and pressing requires a pressing device.

[0003] Application CN202420312757.3 discloses a plywood pressing device, including a base plate; two symmetrically mounted support columns are installed on the base plate, and a pressing plate is vertically arranged between four limiting rods. An upper limiting groove is provided at the top of the fixing member, and a lower limiting groove is provided at the bottom of the fixing member. A spring is installed in the upper limiting groove, and a cavity is provided in the pressing plate. A heating rod is installed in the cavity. When a hydraulic rod pushes upward, the pressing plate moves upward. After being compressed, the spring retracts into the upper limiting groove and the lower limiting groove at the bottom of the upper fixing member. The pressing plate presses the veneers together. The heating rod heats the veneers continuously pressed between the pressing plates, thereby accelerating the solidification of the veneer adhesive. This combination achieves the plywood pressing effect, enabling the simultaneous pressing of multiple plywood pieces. Compared with traditional plywood pressing devices, this device offers better pressing results and higher plywood production quality.

[0004] However, the device still has the following problems: the sheet metal after hot pressing will stick to the pressed plate. The device directly pushes the plywood from one side with a hydraulic cylinder, which requires a lot of force and can easily damage the plywood.

[0005] Therefore, this utility model proposes a new solution. Utility Model Content

[0006] The main purpose of this utility model is to provide a plywood compaction device to overcome the shortcomings of the existing technology.

Multiple first hydraulic push rods are installed at the bottom of the lowest pressing plate. Lifting frames driven by second hydraulic push rods are slidably mounted on both sides of the multiple pressing plates. Multiple cantilever rods corresponding to each pressing plate are installed on opposite sides of the two lifting frames. Grooves that mate with the cantilever rods are formed on the pressing plates.

[0009] Preferably, there are two sets of lifting rods, which are symmetrically installed on the front and rear sides of the lifting frame, and a rotating wheel is rotatably installed on the outer wall of the lifting rod.

[0028] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0029] like Figures 1-6As shown, the plywood compaction device provided in this embodiment includes a base plate 1, four columns 2 are installed on the top of the base plate 1, a top plate 3 is installed on the top of the four columns 2, and multiple pressing plates 4 are installed between the four columns 2. Electric heating wires are provided on the inner sides of the columns 2 and the pressing plates 4. A controller 5 is installed on the top of the top plate 3. Multiple first hydraulic push rods 6 are installed at the bottom of the lowest pressing plate 4. Lifting frames 8 driven by second hydraulic push rods 7 are slidably installed on both sides of the multiple pressing plates 4. Multiple cantilever rods 9 corresponding to the pressing plates 4 are installed on the opposite side of the two lifting frames 8. Grooves 10 that cooperate with the cantilever rods 9 are opened on the pressing plates 4. By setting up a second hydraulic push rod 7, a lifting frame 8, a cantilever rod 9, and a groove 10, after the pressing is completed, the first hydraulic push rod 6 retracts, and multiple pressing plates 4 descend in sequence. At this time, the two lifting frames 8 are slid, so that the cantilever rod 9 inserts into the groove 10. Then, the second hydraulic push rod 7 is activated to push the lifting frame 8 to lift, and the cantilever rod 9 can lift the plywood, so that the plywood is separated from the pressing plate 4, which makes it easier to remove the plywood later.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, two sets of cantilever poles 9 are symmetrically installed on the front and rear sides of the lifting frame 8. Rotary wheels 11 are rotatably mounted on the outer wall of each cantilever pole 9, and the outer surface of each wheel 11 is provided with a wear-resistant layer. By setting two sets of cantilever poles 9 and rotatably mounting the wheels 11 on the outer wall of each cantilever pole 9, the four cantilever poles 9 can stably support the plywood. The wheels 11 facilitate pulling the plywood outwards, thus enabling quick disassembly.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, two mounting plates 12 are fixedly installed in the middle of the top surface of the base plate 1. A bidirectional lead screw 13 is rotatably mounted between the two mounting plates 12. One end of the bidirectional lead screw 13 is connected to a motor 14. Two symmetrically arranged transmission blocks 15 are installed on the outer wall of the bidirectional lead screw 13. A second hydraulic push rod 7 is fixedly installed on the top of the transmission block 15. A first sliding rod 16 located on both sides of the bidirectional lead screw 13 is fixedly connected between the two mounting plates 12. A first sliding hole 17 is opened on the transmission block 15 to slide and connect with the first sliding rod 16. Through the arrangement of the bidirectional lead screw 13, motor 14 and transmission blocks 15, the lifting frame 8 can move closer to and away from the pressing plate 4 by rotating the bidirectional lead screw 13 in both directions.

[0032] In this embodiment, as Figure 1 , Figure 5 and Figure 6As shown, the top of the transmission block 15 is fixedly connected to the second slide rods 18 located on both sides of the second hydraulic push rod 7, and the bottom of the lifting frame 8 is provided with a second sliding hole 19 that is slidably connected to the second slide rods 18. The setting of the second slide rods 18 and the second sliding hole 19 makes the lifting frame 8 more stable in raising and lowering.

[0033] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, two limiting plates 20 are threaded onto the outer wall of the bidirectional lead screw 13. The limiting plates 20 limit the movement range of the lifting frame 8.

[0034] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the column 2 is provided with multiple stepped inner rods 21, with the uppermost inner rod 21 having the smallest diameter. Each of the four corners of the multiple pressing plates 4 has an outer hole 22 for engaging the inner rods 21, and the edges of the inner rods 21 are chamfered. The inner rods 21 and outer holes 22 allow for automatic positioning when the pressing plates 4 separate after pressing, and the chamfers prevent the pressing plates 4 from getting stuck when falling.

[0035] In this embodiment, as Figures 1-6 As shown, the working process of the plywood compaction device provided in this embodiment is as follows:

[0036] Step 1: After pressing is completed, the first hydraulic push rod 6 retracts, and multiple pressing plates 4 descend in sequence;

[0037] Step 2: Start the motor 14 to drive the bidirectional lead screw 13 to rotate, thereby driving the two lifting frames 8 to approach the pressing plate 4, so that the lifting rod 9 is inserted into the groove 10;

[0038] Step 3: Then, activate the second hydraulic push rod 7 to push the lifting frame 8 to rise, and the lifting rod 9 can lift the plywood, so that the plywood is separated from the pressing plate 4, and then the plywood is pulled outward to disassemble it.
