Description

TECHNICAL FIELD

[0001] The present application relates to the field of artificial board processing, in particular to a single-layer cold-pressing continuous microwave heating production mold and production system for artificial boards. BACKGROUND

[0002] Artificial boards (such as plywood, particle board, fiberboard, etc.) are widely used in the fields of construction, furniture, decoration, etc. The traditional production process usually includes: taking wood fibers or other plant fibers as raw materials, applying glue, laying, pre-pressing, and then placing them in a hot press to form a cured adhesive under high temperature and high pressure. In order to obtain a high temperature and high pressure environment, two heating methods are currently mainly used in industry:

[0003] Hot press oil heating: heat is transferred from the boiler to the hot press plate through the circulation of heat conducting oil, and then transmitted to the board blank by the hot press plate. The heating speed of this method is limited by the heat transfer efficiency of the heat conducting oil and the thickness of the hot press plate, and the heating rate is low and the energy consumption is high. Moreover, the heat conducting oil is prone to aging and leakage after long-term use, which poses environmental and safety hazards.

[0004] Electric heating: electric resistance wires are arranged in the hot press plate, which directly generates heat by being electrified. Although the system structure is simple, uneven distribution of electric resistance wires will cause large temperature difference on the surface of the hot press plate, and the power load is high, further increasing the energy consumption.

[0005] Whether it is oil heating or electric heating, both belong to the conduction type heating mode from the surface to the inside, and there is a significant temperature gradient between the center and the surface of the board blank, which causes uneven curing of the adhesive and large internal stress of the finished product, and quality defects such as warping and cracking are prone to occur, so it needs to be optimized and improved.

[0029] The following refers to the drawings Figures 1-6A continuous microwave heating production system for single-layer cold pressing of artificial boards according to an embodiment of the present invention is described. The system includes: a conveying platform 1, an artificial board mold, a cold pressing device, a microwave device, and a board unloading device.

[0030] like Figure 1 As shown, the conveying platform 1 is equipped with a driving component 2, and the conveying platform 1 is provided with a paving area 3, a cold pressing area 4, a microwave area 5 and an unloading area 6 arranged sequentially along the conveying direction.

[0031] like Figures 2-3 As shown, the artificial board mold includes an upper cover plate 8, a plate frame 9, a latch 10, and a transmission component. The plate frame 9 is an annular frame with open upper and lower sides. The upper cover plate 8 is detachably covered on the upper side of the plate frame 9 by the latch 10. The plate frame 9 is provided with heat dissipation holes. The plate frame 9 is provided with a transmission component. The drive component 2 is connected to the transmission machine to drive the artificial board mold to move along the conveying platform 1.

[0032] like Figures 4-6 As shown, a cold pressing device is located in cold pressing zone 4, and is used to press the artificial board mold downwards when it moves to cold pressing zone 4. A microwave device is located in microwave zone 5, and is used to microwave heat the board blank in the artificial board mold when it moves to microwave zone 5. A board unloading device is located in unloading zone 6, and is used to lift the artificial board mold to expose the cured board when it moves to unloading zone 6.

[0033] Specifically, in this design, the upper edge of the frame 9 is provided with an outwardly folded edge 12, and a latch 10 hooks onto the folded edge 12 to connect the upper cover plate 8 to the frame 9. The latch 10 is an existing product, and those skilled in the art can select it according to actual needs. Several heat dissipation holes are provided on the lower side of the frame 9 for dissipating hot air.

[0034] There are multiple drive components 2 on the conveying platform 1, which are arranged at intervals along the conveying direction of the conveying platform 1. The drive component 2 includes a motor and a gear 17 connected to the motor. The transmission component is a rack 11, which is located on the outer side wall of the plate frame 9. The gear 17 meshes with the rack 11. When the motor drives the gear 17 to rotate, it can push the rack 11 to move, thereby realizing the movement of the artificial board mold.

[0035] In addition, in order to guide the movement of the artificial board mold, the lower end of the board frame 9 is provided with several downward protruding guide posts 13, and the conveying platform 1 is provided with guide grooves 14. The guide posts 13 and guide grooves 14 are guided and cooperated to prevent the artificial board mold from shifting.

[0036] In this scheme, the conveying platform 1 is a ring platform, which is divided into a working area and an auxiliary area 7. The working area includes a paving area 3, a cold pressing area 4, a microwave area 5, and an unloading area 6. The unloading area 6 and the paving area 3 are connected through the auxiliary area 7.

[0037] The laying area 3 is mainly to put the board blank or the glued material into the wood-based panel mold. The cold pressing area 4 is used to cold press the board blank or the material in the wood-based panel mold, and the cold pressing device here is a hydraulic press 15.

[0038] The microwave area 5 is used for microwave heating of the board blank, and the microwave device used is arranged in the conveying platform 1, and the upper surface is a microwave-transparent material, and the microwave passes through the microwave-transparent material to heat the board blank.

[0039] The board unloading area 6 is used for unloading the board, and the unloading device is an electric push rod 16 that can be extended up and down, and the electric push rod 16 is multiple and distributed on both sides of the conveying platform 1, and the edge of the upper cover plate 8 exceeds the board frame 9, so that the electric push rod 16 can lift the wood-based panel mold by pushing the upper cover plate 8.

[0040] The specific working process of the scheme is as follows:

[0041] 1. The wood-based panel mold is placed on the conveying platform 1, the guide column 13 is guided and matched with the guide groove 14 of the conveying platform 1, and the rack 11 is matched with the gear 17 of the driving member 2. Then the upper cover plate 8 is opened, the glued material is put into the board frame 9, the upper cover plate 8 is closed, the motor drives the gear 17 to rotate, the rack 11 is moved, and the wood-based panel mold moves to the cold pressing area 4;

[0042] 2. When the wood-based panel mold reaches the cold pressing area 4, the movement is stopped, the hydraulic press 15 descends and presses on the wood-based panel mold, and stops descending when the wood-based panel mold is completely closed. At this time, the upper cover plate 8 and the board frame 9 are locked together by using the lock buckle 10, and then the hydraulic press 15 ascends to release the pressure. Because the upper cover plate 8 has been connected with the board frame 9 together, and the gear 17 is pressed on the rack 11, and the initial tackiness of the adhesive is added, the wood-based panel mold still remains in the compressed state;

[0043] 3. After the cold pressing is completed, the wood-based panel mold continues to move to the microwave area 5, and the upper surface of the microwave area 5 is a microwave-transparent material, and the lower surface of the board frame 9 is open. Therefore, the board blank is directly attached to the microwave-transparent material to receive the microwave, the board blank is heated and solidified, and the hot gas is discharged from the heat dissipation hole of the board;

[0044] 4. After the heated and solidified wood-based panel mold moves to the board unloading area 6, the electric push rod 16 lifts the entire wood-based panel mold upward, and the solidified board material is exposed. Then the board material is pushed out from the side of the platform by the mechanical hand, and then the board is cooled, sanded and stored,

[0045] After the board material is unloaded, the electric push rod 16 descends to reset, and the wood-based panel mold returns to the laying area 3 along the guide groove 14 of the auxiliary area 7, so as to be ready for the next cycle.

[0046] Therefore, the scheme can realize single-layer cold pressing and continuous microwave drying of the board blank during the production of the artificial board, and compared with traditional oil heating and electric heating, the microwave heating effectively improves the production efficiency and quality of the artificial board, reduces power consumption, and realizes the goal of high yield and low consumption.

[0047] Although some embodiments of the present application have been shown and described, it would be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the application, and all such changes, modifications, substitutions and alterations are intended to be within the scope of the claims of the present application.
