Description

Technical Field

[0001] The utility model belongs to the technical field of hot pressing of blockboards, and particularly relates to a hot pressing device for blockboard processing. Background Art

[0002] The hot pressing process of blockboards is one of the key steps in manufacturing blockboards. Through high temperature and high pressure, the middle layer and the surface veneers of the blockboard materials are tightly bonded together to ensure the strength, flatness and stability of the boards.

[0003] At present, there are some hot pressing devices on the market. For example, a blockboard hot press is disclosed on the Chinese Patent Network, and its publication number is CN209408735U. This hot press can be used for the hot pressing process of blockboards, but there are some defects and deficiencies to be improved: (1) Before hot pressing the blockboard, some existing hot pressing devices need to stack the coated middle layer and surface veneers in sequence to form a board blank to be hot pressed. During the stacking process, it is difficult to accurately align the middle layer and the surface veneers, so misalignment is likely to occur; (2) Some existing hot pressing devices usually apply a pressing force to the hot pressing plate through a hydraulic cylinder, so as to squeeze the board up and down through the hot pressing plate. However, the pressing force applied by the hydraulic cylinder to the hot pressing plate often only focuses on one point, which makes the hot pressing plate unable to remain horizontal during the hot pressing process, resulting in uneven stress on the board, and then affecting the flatness and strength of the board; (3) Due to the reason of the structural design of some existing hot pressing devices, it is difficult to evenly distribute the surface temperature of the hot pressing plate, and the heat cannot be fully and evenly transferred to the board during hot pressing, so that the board has poor local bonding or uneven surface due to uneven heating. Therefore, in view of the above problems, it is of great significance to provide a hot pressing device for blockboard processing according to the utility model. Summary of the Utility Model

[0004] The utility model provides a hot pressing device for processing blockboard. Through the combined action of the first positioning mechanism and the second positioning mechanism, the middle layer and the surface veneer of the blockboard material can be positioned simultaneously from the left and right sides and the front and back sides, so as to ensure that the middle layer and the surface veneer can be accurately aligned during the stacking process without misalignment. Through a plurality of transmission rods, the force on the hot pressing plate can be effectively dispersed, so as to avoid the concentrated pressure force at one point causing the hot pressing plate to be unable to maintain horizontal during the hot pressing process, thereby effectively avoiding the influence of uneven stress on the flatness and strength of the board. Through the mutual cooperation between the guide rod and the guide hole, a limiting effect can be achieved, thereby effectively avoiding the inclination and deviation of the hydraulic plate during the movement, which affects the hot pressing effect of the hot pressing plate. Through a plurality of heat conducting sheets, the heat generated by the heating wire can be fully absorbed and evenly transferred to the surface of the hot pressing plate, so that the surface temperature distribution of the hot pressing plate is uniform, thereby ensuring that the heat can be fully and evenly transferred to the board through the hot pressing plate during hot pressing, and avoiding local poor bonding or uneven surface of the board due to uneven heating.

[0034] Please refer to Figure 1-8 As shown, a hot pressing device for processing blockboard in the present utility model includes a support plate 1. A plurality of support legs 2 are fixedly connected to the bottom of the support plate 1, and a support base 3 is fixedly connected to the top of the support plate 1. A hot press table 4 is fixedly connected to the top of the support base 3. The hot press table 4 is used to place the intermediate layer and surface veneer of the blockboard material to be hot pressed. A pair of first chutes 5 and a pair of second chutes 6 are respectively formed on the surface of the hot press table 4, and a first positioning mechanism and a second positioning mechanism are respectively arranged on the left and right sides and the front and rear sides of the hot press table 4. A fixed frame 7 is fixedly connected to the top of the support plate 1, and a hot pressing mechanism is arranged on the fixed frame 7;

[0035] The first positioning mechanism includes a first electric telescopic rod 8, which is respectively installed on the inner walls of both sides of the fixed frame 7. The end of the output shaft of the first electric telescopic rod 8 is fixedly connected with a first movable plate 9. A pair of first positioning rods 10 are fixedly connected to the top of the first movable plate 9. By driving the first electric telescopic rod 8, the first movable plate 9 together with the first positioning rods 10 can be driven to move. When the first positioning rods 10 are attached to the left and right sides of the blockboard sheet material, the sheet material can be positioned from the left and right sides, so as to ensure that the left and right sides of the middle layer and the surface veneer of the blockboard material can be accurately aligned during stacking;

[0036] The second positioning mechanism includes a second electric telescopic rod 11, which is respectively installed on the front end face and the rear end face of the support base 3. The end of the output shaft of the second electric telescopic rod 11 is fixedly connected with a second movable plate 12. A pair of second positioning rods 13 are fixedly connected to the top of the second movable plate 12. By driving the second electric telescopic rod 11, the second movable plate 12 together with the second positioning rods 13 can be driven to move. When the second positioning rods 13 are attached to the front and rear sides of the blockboard sheet material, the sheet material can be positioned from the front and rear sides, so as to ensure that the front and rear sides of the middle layer and the surface veneer of the blockboard material can be accurately aligned during stacking;

[0037] The hot pressing mechanism includes a hydraulic cylinder 14, which is installed on the top of the fixed frame 7. The bottom end of its output shaft is fixedly connected with a hydraulic plate 15. A plurality of transmission rods 16 are fixedly connected to the bottom of the hydraulic plate 15. The bottom of the transmission rods 16 is fixedly connected with a mounting plate 17. A hot pressing plate 18 is installed at the bottom of the mounting plate 17. The inside of the hot pressing plate 18 is a hollow structure. A plurality of heat conducting sheets 19 are fixedly connected to the bottom of the hot pressing plate 18. And heating seats 20 are installed on the inner walls of both sides of the hot pressing plate 18. A plurality of electric heating wires 21 are electrically connected between the heating seats 20. The heating seats 20 can be externally connected to a power supply or can integrate a rechargeable battery inside. The heating seats 20 can supply power to the electric heating wires 21. When the electric heating wires 21 are electrified, heat can be generated to heat the hot pressing plate 18 to the required temperature. By driving the hydraulic cylinder 14, the hydraulic plate 15 can be driven to move up and down. When the hydraulic plate 15 moves, it can drive the mounting plate 17 together with the hot pressing plate 18 to move up and down through each transmission rod 16 until the hot pressing plate 18 contacts the sheet material on the hot pressing table 4. At this time, the pressing force applied by the hydraulic cylinder 14 can be used to hot press the sheet material through the hot pressing plate 18, so that the middle layer and the surface veneer of the blockboard material are tightly combined together.

[0038] Among them, the diameters of the first positioning rods 10 and the second positioning rods 13 are respectively equal to the groove widths of the first sliding grooves 5 and the second sliding grooves 6, and the centers of each of the first positioning rods 10 and the second positioning rods 13 and the centers of each of the first sliding grooves 5 and the second sliding grooves 6 are located on the same straight line. The first positioning rods 10 and the second positioning rods 13 can move along the first sliding grooves 5 and the second sliding grooves 6 respectively, so as to position the middle layer and the surface veneer of the blockboard material from the left and right sides and the front and back sides simultaneously, thereby ensuring that the middle layer and the surface veneer can be accurately aligned during the stacking process without dislocation. Moreover, the first positioning rods 10 and the second positioning rods 13 can move according to the size of the board, so as to position boards of different sizes.

[0039] Among them, a silica gel sleeve is sleeved on the rod bodies of each of the first positioning rods 10 and the second positioning rods 13. The silica gel sleeve can be fixed on the first positioning rods 10 and the second positioning rods 13 by means of glue or the like. When the first positioning rods 10 and the second positioning rods 13 are attached to the side walls of the board, the silica gel sleeve can play a role of buffering and protection to prevent the side walls of the board from directly contacting the first positioning rods 10 and the second positioning rods 13 and causing collision and wear.

[0040] Among them, the transmission rods 16 are linearly distributed at equal intervals along the length and width directions of the mounting plate 17. When the hydraulic cylinder 14 applies a pressing force to the hot pressing plate 18, the pressing force of the hot pressing plate 18 can be effectively dispersed through the plurality of transmission rods 16, so as to avoid the pressing force being concentrated at one point and causing the hot pressing plate 18 to be unable to remain horizontal during the hot pressing process, thereby effectively avoiding the influence of uneven stress on the flatness and strength of the board.

[0041] Among them, a plurality of guide holes 22 are formed on the surface of the hydraulic plate 15, and a plurality of guide rods 23 are fixedly connected to the inner wall of the top of the fixing frame 7. The number of the guide rods 23 is the same as that of the guide holes 22, and the diameters are equal. Each of the guide rods 23 passes through the corresponding guide hole 22. When the hydraulic plate 15 moves up and down, the mutual cooperation between the guide rods 23 and the guide holes 22 can play a role of limiting, thereby effectively avoiding the inclination and deviation of the hydraulic plate 15 during the movement process and affecting the hot pressing effect of the hot pressing plate 18.

[0042] Among them, both sides of the bottom of the mounting plate 17 are fixedly connected with a plurality of screw rods 24. A nut 25 that mates with the screw rod 24 is threadedly connected to the screw rod 24. Both sides of the hot pressing plate 18 are L-shaped and are provided with a plurality of mounting holes 26. The number of mounting holes 26 is the same as that of the screw rods 24, and the diameters are equal. The center of each mounting hole 26 corresponds to the center of each screw rod 24 one by one. Each screw rod 24 can be aligned and pass through the corresponding mounting hole 26. At this time, the nut 25 is threadedly connected to each screw rod 24 and tightened. The hot pressing plate 18 can be fixed to the bottom of the mounting plate 17 through the mutual cooperation among the screw rod 24, the mounting hole 26, and the nut 25. By unscrewing the nut 25, the hot pressing plate 18 can be removed from the mounting plate 17 so as to maintain and replace the hot pressing plate 18 and related components.

[0043] Among them, the heat conducting sheet 19 is strip-shaped, and the heat conducting sheets 19 are linearly distributed at equal intervals along the length direction of the hot pressing plate 18. The heat conducting sheet 19 is made of a metal material with strong heat conducting performance and is fixed by means such as glue. The heat generated by the heating wire 21 can be fully absorbed by the multiple heat conducting sheets 19 and evenly transferred to the surface of the hot pressing plate 18, so that the surface temperature distribution of the hot pressing plate 18 is uniform, thereby ensuring that the heat can be fully and evenly transferred to the plate through the hot pressing plate 18 during hot pressing, and avoiding local poor bonding or uneven surface of the plate due to uneven heating.

[0044] The circuits, electronic components, and chip modules involved in the present utility model are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to software and methods either.

[0045] The standard parts used in the application documents can be purchased from the market. All the components in the present application documents can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art. The electrical components described in this article are all electrically connected to the external main controller and 220V mains power, and the main controller can be a conventional known device such as an LED lamp body for control.

[0046] The working principle of the present utility model is:

[0047] When the utility model is in use, first, all the electrical components in the hot pressing device are externally connected to a control switch and a power supply through wires, and the middle layer of the glued blockboard is placed on the hot pressing table 4. Then, the first electric telescopic rod 8 and the second electric telescopic rod 11 are respectively driven to drive the first movable plate 9 and the second movable plate 12 together with the first positioning rod 10 and the second positioning rod 13 to move along the first chute 5 and the second chute 6 until the first positioning rod 10 and the second positioning rod 13 are respectively attached to the left and right sides and the front and back sides of the middle layer of the blockboard. Then, the surface veneer of the blockboard is stacked on the middle layer to ensure that the middle layer and the surface veneer can be accurately aligned during the stacking process. Then, the heating seat 20 supplies power to the heating wire 21 to heat the hot pressing plate 18 to the required temperature. At the same time, the hydraulic cylinder 14 is driven to drive the hydraulic plate 15 to move downward. When the hydraulic plate 15 moves, it can drive the mounting plate 17 together with the hot pressing plate 18 to move downward through each transmission rod 16 until the hot pressing plate 18 contacts the plate on the hot pressing table 4. At this time, the pressing force applied by the hydraulic cylinder 14 can be used to hot press the plate through the hot pressing plate 18 so that the middle layer and the surface veneer of the blockboard material are tightly combined together. After that, according to the thickness of the plate and the type of glue, a certain time is maintained to ensure that the glue is completely cured.
