Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood board hot press technology, and in particular to a wood board hot press. Background Technology
[0002] Hot presses are crucial equipment in the production of composite wood panels. Existing hot presses typically involve placing layers of trimmed wood panels or veneers onto a hot press plate, applying hot-pressing adhesive to each layer, and then pressing the panels together to form the desired shape. To improve production efficiency, multi-layer hot presses are commonly used in current technology. However, existing multi-layer hot presses cannot press panels of varying widths, thus reducing the practicality of the equipment.
[0003] CN 222115397 U discloses a multi-layer wood board hot press, including a cooling device body and a hot press device body. In use, the device is first placed in a suitable position by the base of the cooling device body. Then, the wood board abutments at the left and right ends of the upper side of the lower hot press plate, which are lower than the height of the wood board, are moved to the left and right sides respectively. Then, the wood board to be pressed is placed on the upper side of the lower hot press plate. Then, the wood board abutments will move along the wood board abutment groove to one side of the wood board under the action of the first telescopic spring until the wood board abutments completely abut the wood board. At this time, the wood board is fixed on the lower hot press plate, which can prevent the wood board from shifting during the subsequent pressing process of the hot press plate, thereby improving the pressing effect of the hot press plate. Since the device fixes the wood board by moving the wood board abutments, the device can adapt to wood boards of different widths, thereby improving the practicality of the device.
[0004] However, due to the limitation of the board bottom plate, the aforementioned wood hot press can only process multi-layer wood boards where the second layer of wood is no higher than the board bottom plate. If the second layer of wood is higher than the board bottom plate, the bottom plate will not be able to limit the upper layer of wood, causing misalignment between the upper and lower layers, which affects the pressing effect. Furthermore, during the pressing process, if the thickness of the board is lower than the board bottom plate, the board bottom plate will restrict the downward pressure of the hot press plate, preventing the board from being compacted. Therefore, the thickness of the boards that the aforementioned wood hot press can process is limited, and the equipment has low versatility. Utility Model Content
[0005] In order to overcome the above-mentioned defects in the prior art, this utility model provides a wood board hot press.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a wood board hot press machine, including a hot press machine body, in which several sets of placement plates are elastically and movably installed. Each set of placement plates has a limiting mechanism movably installed at the top left and right ends. The limiting mechanism includes a lower fixed plate, an upper fixed plate elastically and movably installed on the lower fixed plate, several sets of lower limiting baffles fixedly installed at the top of the lower fixed plate, and several sets of upper limiting baffles fixedly installed at the bottom of the upper fixed plate. The lower limiting baffles and the upper limiting baffles are arranged alternately.
[0007] Furthermore, the lower fixing plate, the upper fixing plate, the lower limit baffle, and the upper limit baffle are flush with each other at the ends near the middle of the placement plate. Several sets of first springs are fixedly installed at the end of the lower fixing plate away from the middle of the placement plate. The other ends of the first springs are fixedly connected to the upper fixing plate. Guide blocks are provided on the front and rear side walls of the lower limit baffle, and guide grooves matching the guide blocks are provided on the front and rear side walls of the upper limit baffle.
[0008] Furthermore, the lower fixed plate has connecting parts at both ends, and several sets of light rods are slidably installed on the connecting parts. The light rods are fixedly installed on the side wall of the placement plate, and electric telescopic rods are fixedly installed at the left and right ends of the placement plate respectively. The power output end of the electric telescopic rod is fixedly connected to the lower fixed plate.
[0009] Furthermore, mounting grooves are provided on the inner walls of the left and right sides of the hot press body. Several sets of first guide rods are fixedly installed in the mounting grooves. Several sets of second springs are provided at the bottom of each set of placement plates. The number of second springs is equal to that of the first guide rods. The second springs are respectively fitted onto the first guide rods. Connecting plates are fixedly installed at the left and right ends of the placement plates. The connecting plates are slidably connected to the first guide rods.
[0010] Furthermore, a hot press plate is provided above the uppermost placement plate, and several sets of second guide rods are fixedly installed on the top of the hot press plate. The second guide rods are slidably installed on the top wall of the hot press body. A hydraulic cylinder is fixedly installed on the top of the hot press body, and the power output end of the hydraulic cylinder is fixedly connected to the hydraulic rod.
[0011] Furthermore, a heat-conducting pipe is fixedly installed inside each of the placement plates. The heat-conducting pipe has a bent and folded structure. An oil inlet and an oil outlet are fixedly installed at both ends of the heat-conducting pipe, and an oil pipe groove is opened on the side wall of the mounting groove.
[0012] The beneficial effects of this utility model are that, through the design of an upper fixed plate that is elastically and movably installed on a lower fixed plate, and the connection between the lower fixed plate and the upper fixed plate is through a first spring, the upper fixed plate will be squeezed downward along with the plate during the pressing process, thereby ensuring that the plate is compacted. Furthermore, when placing the plate, the height of the upper fixed plate can be greater than the thickness of the plate, thereby preventing misalignment between the upper and lower wooden boards. Therefore, it can process plates of various thicknesses, which is beneficial to improving the versatility of the equipment. Attached Figure Description

[0020] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.
[0021] according to Figure 1-5As shown, a wood board hot press includes a hot press body 1. Several sets of placement plates 2 are elastically and movably installed inside the hot press body 1. Limiting mechanisms are movably installed at the top left and right ends of each set of placement plates 2. The limiting mechanisms include a lower fixed plate 3, an upper fixed plate 4 elastically and movably installed on the lower fixed plate 3, several sets of lower limit baffles 5 are fixedly installed at the top of the lower fixed plate 3 by bolts, and several sets of upper limit baffles 6 are fixedly installed at the bottom of the upper fixed plate 4 by bolts. The lower limit baffles 5 and the upper limit baffles 6 are staggered.
[0022] In this embodiment, the lower fixing plate 3, the upper fixing plate 4, the lower limiting baffle 5, and the upper limiting baffle 6 are flush with each other at the ends near the middle of the placement plate 2. Several sets of first springs 7 are fixedly installed at the end of the lower fixing plate 3 away from the middle of the placement plate 2. The other end of the first spring 7 is fixedly connected to the upper fixing plate 4. Guide blocks 51 are provided on the front and rear side walls of the lower limiting baffle 5. Guide grooves 61 that match the guide blocks 51 are provided on the front and rear side walls of the upper limiting baffle 6. The guide blocks 51 and the guide grooves 61 are inserted together. With the cooperation of the guide blocks 51 and the guide grooves 61, the movement direction of the upper fixing plate 4 is limited. During the operation, the upper fixing plate 4 will be pressed downward along with the plate. After the hot pressing is completed, the upper fixing plate 4 will be reset upward under the action of the first springs 7.
[0023] In this embodiment, the lower fixing plate 3 has connecting parts 31 at both ends. Several sets of light rods 8 are slidably installed on the connecting parts 31. Preferably, there are two sets of light rods 8. The light rods 8 are fixedly installed on the side wall of the placement plate 2 by brackets. The left and right ends of the placement plate 2 are respectively fixedly installed with electric telescopic rods 9 by brackets. The power output end of the electric telescopic rod 9 is fixedly connected to the lower fixing plate 3. The lower fixing plate 3 is driven to move along the light rods 8 by the electric telescopic rods 9, thereby adjusting the distance between the limit baffles at both ends to suit plates of different widths.
[0024] In this embodiment, mounting grooves 10 are provided on the inner walls of the left and right sides of the hot press body 1. Several sets of first guide rods 11 are fixedly installed in the mounting grooves 10. Several sets of second springs 12 are provided at the bottom of each set of placement plates 2. The number of second springs 12 is equal to the number of first guide rods 11. The second springs 12 are respectively fitted onto the first guide rods 11. Connecting plates 13 are fixedly installed at the left and right ends of the placement plate 2. The connecting plates 13 are slidably connected to the first guide rods 11. A hot press plate 14 is provided above the uppermost placement plate 2. Several sets of second guide rods are fixedly installed on the top of the hot press plate 14. The rod 15, preferably two sets of second guide rods 15, are slidably mounted on the top wall of the hot press body 1. A hydraulic cylinder 16 is fixedly mounted on the top of the hot press body 1. The power output end of the hydraulic cylinder 16 is fixedly connected to the hydraulic rod. The hot press plate 14 moves along the second guide rod 15 under the drive of the hydraulic cylinder 16. During the production process, the hydraulic cylinder 16 drives the hot press plate 14 to move downward and squeeze the plate. After the uppermost plate is compacted, the uppermost placement plate 2 is pressed downward and squeezes the plate below it, thereby causing the placement plate 2 to press down in sequence to complete the hot pressing of multiple layers of plates.
[0025] In this embodiment, a heat-conducting pipe 17 is fixedly installed in each set of placement plates 2. The heat-conducting pipe 17 has a bent and folded structure to increase the contact between the heat-conducting pipe 17 and the placement plate 2, so that the heat is more uniform. An oil inlet 18 and an oil outlet 19 are fixedly installed at both ends of the heat-conducting pipe 17, respectively. An oil pipe groove 20 is opened on the side wall of the mounting groove 10. Heat-conducting oil flows in the heat-conducting pipe 17. A heating device (not shown in the figure) is installed at the bottom of the hot press body 1. The heating device is connected in parallel with the heat-conducting pipe 17 inside each layer of placement plate 2 through an oil supply pipe. The heat-conducting oil circulates between the heat-conducting pipe 17 and the heating device through the oil supply pipe.
[0026] In use, the materials to be processed are first placed on the placement plates 2 of each layer. Then, the electric telescopic rod 9 is activated, which drives the lower fixed plates on both sides to move closer to each other until the limit baffle completely abuts the materials. This prevents misalignment between the boards during the subsequent pressing process. After the materials are fixed, the hydraulic cylinder 16 is activated, which drives the hot pressing plate 14 to descend. The hot pressing plate 14 first contacts the upper fixed plate 4 on the uppermost placement plate 2. The upper fixed plate 4 descends with the hot pressing plate 14 until the materials on the current placement plate 2 are compacted. Then, the uppermost placement plate 2 descends with the hot pressing plate 14 to squeeze the materials below, thus completing the hot pressing of multiple layers of materials. During the processing, high-temperature heat transfer oil circulates in the heat pipe 17, which heats the placement plates 2 to improve the hot pressing effect.
