Description

Technical Field

[0001] This utility model relates to the technical field of plywood production, and in particular to a plywood shaping device. Background Technology

[0002] In the plywood production process, after the sheets are coated with glue and stacked, the stacked sheets are placed on a press. The press plate applies continuous downward pressure and hot oil is introduced into the internal circuit of the press plate. Through high temperature and high pressure, the glue is completely dispersed inside the board to improve the board's strength. After the board is pressed at high temperature, pressure needs to be continued and cooling water needs to be introduced into the internal circuit of the press plate. Cooling during the pressing process prevents deformation due to temperature difference and springback stress after the board is removed from the press.

[0003] In existing shaping devices, hot oil is introduced into the internal circuit of the pressure plate to heat the pressure plate and the sheet material beneath it. Then, cooling water is introduced into the circuit to cool the sheet material. However, during the cooling process, the device remains stationary and maintains pressure, and the next sheet material can only be shaped after it has completely cooled down, which takes up equipment time. After the shaped sheet material is removed, the pressure plate needs to be reheated, which also takes up equipment time. The proportion of equipment operation time is much lower than the proportion of time spent in the hot and cold cycles, resulting in low efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to provide a plywood shaping device that cools hot-pressed boards by pressing them with a placement rack, thereby improving the production efficiency of the equipment.

[0006] To achieve the above objectives, this utility model proposes a plywood shaping device, comprising a box, a placement rack, and a pressing assembly. The placement rack includes at least two sets of support platforms, each set of support platforms including a support plate, a connecting rod, and a limiting assembly. The support plate is disposed inside the box, and the support plates inside each set of support platforms are arranged vertically. The connecting rod is fixedly connected to both sides of the support plate, and the connecting rods inside each set of support platforms are interleaved. The limiting assembly is disposed on the support plate, and the pressing assembly is disposed on the box.

[0007] In addition, the plywood shaping device proposed above according to this utility model may also have the following additional technical features: Specifically, the connecting rod is C-shaped, and the short sides of the connecting rods inside each set of support platforms are staggered vertically.

[0008] Specifically, the box is equipped with a lifting assembly, which includes a connecting plate and a first driving component. The connecting plate is located at the lower end of the placement frame, and the first driving component is retractable with one end connected to the connecting plate and the other end connected to the box.

[0009] Specifically, the limiting component includes a limiting hole and a limiting rod, wherein the limiting hole is formed on the support plate, one end of the limiting rod is fixedly connected to the support plate, and the other end of the limiting rod is slidably connected in the limiting hole formed on the upper support plate.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The plywood shaping device of this utility model embodiment will now be described with reference to the accompanying drawings.

[0017] like Figures 1-6 As shown, the plywood shaping device of this utility model embodiment may include a box 1, a placement rack 3 and a pressing component 4.

[0018] The pressure-holding component 4 is installed on the housing 1.

[0019] It should be noted that the box 1 is used as the basic support for the entire device. Adjustable feet are installed at the lower end of the box 1 to adjust the stability of the device. The pressing component 4 is used to apply pressure to the upper end of the placement frame 3 to press the plywood.

[0020] In one embodiment of this utility model, ventilation windows can be installed on the side wall of the box 1 to allow external air to enter the box 1. The external cold air is conducted by the support plate 31 to assist in the cooling of the plate.

[0021] In one embodiment of this utility model, a support roller can be installed on the front side of the box 1, and a push rod driven by a cylinder can be installed on the hot press. The cylinder is connected to an external air supply device, and the hot-pressed plate is pushed backward by the cylinder. During the pushing, the plate is stably supported at the bottom by the support roller.

[0022] The placement rack 3 includes at least two sets of support platforms, each set of support platforms including a support plate 31, a connecting rod 32 and a limiting component 33.

[0023] The support plate 31 is installed inside the housing 1. The support plates 31 inside each set of support platforms are arranged vertically. The connecting rods 32 are fixedly connected to both sides of the support plate 31. The connecting rods 32 inside each set of support platforms are intertwined. The limiting component 33 is installed on the support plate 31.

[0024] It should be noted that the connecting rod 32 drives the movement of each layer of support plates 31 inside the box 1, and the limiting component 33 maintains the vertical arrangement between the multiple support plates 31.

[0025] In one embodiment of this utility model, a water channel can be opened inside the support plate 31. The water channel is a continuous S-shaped water channel. The water channel is connected to an external cooling water source, and a cooling water heat dissipation device is installed at the water source. The external cooling water source is pumped by a liquid pump and then transported to the water channel inside the support plate 31 through a high-temperature resistant stainless steel metal hose. The cooling water circulates in the water channel. The heat of the plate is conducted through the support plate 31 and carried out by the flowing cooling water.

[0026] In one embodiment of this utility model, placement grooves can be provided at the upper and lower ends of the support plate 31. The height of the upper and lower placement grooves is matched with the preset thickness of the plate. When two adjacent support plates 31 are pressed together, a cavity is formed between the placement grooves to wrap the plate and control the thickness of the plate.

[0027] Specifically, the operator places the device on one side of the hot press. In the initial state, the holding component 4 controls the lowermost support plate 31 to align with the table surface of the hot press. At the same time, the interlaced connecting rods 32 stretch each other to make the support plates 31 have equal gaps.

[0028] During use, after the hydraulic device heat-presses the sheet material, the operator manually pushes or the push rod on the hot press pushes the sheet material onto the support plate 31 aligned with the hot press table. Then, the holding component 4 controls the upper support plate 31 to slide downwards, aligning the second support plate 31 with the hot press table, waiting for the next sheet material to be placed. This process is repeated, placing the sheet material layer by layer between the support plates 31 from bottom to top.

[0029] After the boards are placed, the support plate 31 is moved down by the pressing component 4. After the support plate 31 contacts the lower end face of the box 1, it transmits the pressure to the plywood. The support plates 31 of each layer distribute the pressure evenly to each board. At this time, cooling water is introduced through the water channel opened inside the support plate 31. The heat is carried away from the board by the thermal conductivity of the metal plate, thus achieving cooling under the pressing state.

[0030] In one embodiment of this utility model, such as Figure 6 As shown, the connecting rod 32 can be C-shaped, and the short sides of the connecting rod 32 inside each set of support platforms are staggered vertically.

[0031] It should be noted that the C-shaped connecting rod 32 keeps the device in its initial state. When the holding device lifts the placement frame 3, the spacing between each support plate 31 is maintained by the staggered C-shaped connecting rod 32. When the holding assembly 4 controls the placement frame 3 to descend, the support plates 31 are attached layer by layer from bottom to top.

[0032] In one embodiment of this utility model, such as Figure 4 As shown, a lifting assembly 2 is installed inside the housing 1. The lifting assembly 2 may include a connecting plate 21 and a first driving member 22. The connecting plate 21 is located at the lower end of the placement rack 3. The first driving member 22 is telescopic and one end of it is connected to the connecting plate 21, and the other end of the first driving member 22 is connected to the housing 1.

[0033] It should be noted that an installation groove is opened at the lower end of the box body 1, and the first drive component 22 is installed inside the installation groove. The telescopic end of the first drive component 22 abuts against the lower end of the connecting plate 21, controlling the connecting plate 21 to slide up and down inside the box body 1. The first drive component 22 supports the connecting plate 21 to rise and fall inside the box body 1. After the first drive component 22 retracts into the installation groove, the connecting plate 21 contacts the bottom end of the box body 1, transmitting the pressure of the pressing component 4 to the box body 1. The first drive component 22 is an electric telescopic rod. With precise control of the electric telescopic rod, when the support plate 31 is flush with the hot press table, the support plate 31, which has already been placed with the plate, rises upward under the support of the first drive component 22, so that the upper and lower ends of the plate are in contact with the support plate 31, and the plate is initially pressed, providing initial positioning for subsequent pressing and shaping.

[0034] In one embodiment of this utility model, such as Figure 5 As shown, the limiting component 33 may include a limiting hole 331 and a limiting rod 332.

[0035] The limiting hole 331 is opened on the support plate 31, one end of the limiting rod 332 is fixedly connected to the support plate 31, and the other end of the limiting rod 332 is slidably connected in the limiting hole 331 opened in the upper support plate 31.

[0036] It should be noted that, with the cooperation of the limiting rod 332 and the limiting hole 331, when the interlaced connecting rods 32 separate, the verticality between the upper and lower support plates 31 is limited, so as to keep the support plates 31 relatively horizontal.

[0037] In one embodiment of this utility model, such as Figure 4 As shown, the pressure holding assembly 4 includes a connecting seat 41 and a second driving member 42.

[0038] The connecting seat 41 is located on the upper end of the placement rack 3, the second driving member 42 is retractable and one end is connected to the placement rack 3, and the other end of the second driving member 42 is connected to the box 1.

[0039] It should be noted that the connecting seat 41 described in this embodiment is fixedly connected to the upper part of the uppermost support plate 31. The pressure of the second driving member 42 is evenly distributed to the support plate 31 through the connecting seat 41. The second driving member 42 is an electric telescopic rod, which provides stable, continuous and adjustable pressure for holding the plywood.

[0040] In one embodiment of this utility model, a position sensor is installed inside the housing 1. The signal from the position sensor is transmitted to a controller outside the second drive component 42. The second drive component 42 and the position sensor are respectively connected to the controller. The position sensor monitors the position of the support plate 31, and the obtained position data is transmitted to the controller. The controller sends a control signal to the second drive component 42, and then the second drive component 42 pushes the support plate 31 to a preset position (a position where the support plate 31 is flush with the hot press table).

[0041] In summary, the plywood shaping device of this utility model moves the cooling of the board to a separate placement rack, eliminating the need for the hot press to undergo temperature circulation and pressure holding processes, allowing the hot press to operate continuously and thus improving production efficiency.
