Description

Technical Field

[0001] This utility model relates to the field of fiberboard hot pressing technology, and in particular to a fiberboard multi-face feeding hot press. Background Technology

[0002] Fiberboard, also known as MDF, is a type of engineered wood product. It is mainly made from wood fibers or other plant fibers, along with a suitable amount of resin adhesive, and manufactured through a high-temperature and high-pressure process.

[0003] Fiberboard is widely used in shoe insoles and waist plates, providing good support and exhibiting good flexibility and ease of machining.

[0004] During the processing of fiberboard, it is processed by hot pressing. During the hot pressing process, the high temperature and high pressure help to tightly bond the fibers, forming a stronger and more stable structure, thereby improving the bending strength and dimensional stability of the fiberboard.

[0005] Currently, most hot presses have a heating structure in the hot pressing section. Generally, the hot pressing plate is a hot pressing structure that can move up and down at the top and cooperates with the plate mold. Although this method can perform hot pressing processing on fiberboard materials, the overall heating is not uniform enough, which leads to the inability to guarantee the uniformity and efficiency of heating. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned shortcomings in the existing technology and to propose a fiberboard multi-face feeding hot press.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a fiberboard multi-face feeding hot press, including a base, four legs fixedly installed on the upper end of the base, and a hot press lower mold fixed at the end of the four legs, and a plate groove is opened on the upper end of the hot press lower mold;

[0009] Both sides of the hot pressing mold are welded and fixed with side platforms. The upper end of the side platform is provided with a support frame, and the lower end of the support frame is fixedly assembled to the surface of the side platform by screws.

[0010] A first cylinder is fixed to the inner side of the side platform, and a first piston rod for extension and retraction is provided inside the first cylinder. A hot pressure plate is provided at the end of the first piston rod, and the upper end of the hot pressure plate is fixedly assembled with the end of the first piston rod by screws.

[0011] A first heating element is inserted inside the hot pressing mold, and the end of the first heating element is fixedly assembled to the surface of the hot pressing mold by screws.

[0012] A second heating element is inserted inside the hot press plate, and the end of the second heating element is fixedly assembled to the surface of the hot press plate by screws.

[0013] In detail, the number of the first heating element and the number of the second heating element are both at least three, and they are equidistantly distributed along the corresponding horizontal direction.

[0014] In detail, a first heat-conducting plate is welded and fixed to the lower end of the hot-pressing mold, and a first bent pipe is embedded and fixed in the first heat-conducting plate. A first cold water inlet and a first cold water outlet are respectively provided at both ends of the first bent pipe.

[0015] In detail, a second heat-conducting plate is welded and fixed to the upper end of the hot press plate, and a second bent pipe is embedded and fixed in the second heat-conducting plate. A second cold water inlet and a second cold water outlet are respectively provided at both ends of the second bent pipe.

[0016] In detail, both the first and second heat-conducting plates are made of aluminum alloy.

[0017] In detail, a rod sleeve is provided through the bottom of the plate groove, and the rod sleeve passes through the first heat-conducting plate. A top rod slides through the inside of the rod sleeve, and the rod sleeve is staggered with the first bent tube and the first electric heating tube respectively.

[0018] In detail, a second cylinder is also fixed to the upper end of the base. The second cylinder has a second piston rod for extension and retraction inside. The upper end of the second piston rod is fixedly assembled with the lower end of the push rod by screws.

[0019] The design scheme proposed in this utility model has the following beneficial effects in application:

[0020] 1. By combining the hot pressing mold and the hot pressing plate, sufficient pressure can be applied during fiberboard processing. At the same time, electric heating tubes are embedded in the hot pressing mold and the hot pressing plate, which can heat the machine while applying pressure to achieve hot pressing processing. After hot pressing, circulating low-temperature water is introduced through two bends to quickly cool and shape the hot-pressed fiberboard, which facilitates stable forming of the fiberboard when unloading.

[0021] 2. By adding an ejector rod structure to the plate groove of the hot pressing mold, the ejector rod can be pushed upward by extending the second piston rod of the second cylinder during material removal, thereby ejecting the shaped fiberboard from the plate groove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-4 A fiberboard multi-face feeding hot press includes a base 10, four support legs 11 are fixedly installed on the upper end of the base 10, and a hot pressing lower mold 12 is fixed at the end of the four support legs 11. A plate groove 13 is opened at the upper end of the hot pressing lower mold 12.

[0029] Both sides of the hot pressing mold 12 are welded and fixed with side platforms 19. The upper end of the side platform 19 is provided with a support frame 14, and the lower end of the support frame 14 is fixedly assembled to the surface of the side platform 19 by screws.

[0030] A first cylinder 15 is fixed to the inner side of the side platform 19, and a first piston rod for extension and retraction is provided inside the first cylinder 15. A hot pressure plate 16 is provided at the end of the first piston rod, and the upper end of the hot pressure plate 16 is fixedly assembled with the end of the first piston rod by screws.

[0031] A first heating element 17 is inserted inside the hot pressing mold 12, and the end of the first heating element 17 is fixedly assembled to the surface of the hot pressing mold 12 by screws.

[0032] A second heating element 18 is inserted inside the hot press plate 16, and the end of the second heating element 18 is fixedly assembled to the surface of the hot press plate 16 by screws.

[0033] It should be further noted that the number of the first heating tube 17 and the number of the second heating tube 18 are both at least three, and they are equidistantly distributed along the corresponding horizontal direction. Through the heating tubes distributed vertically, multi-faceted heating can be achieved when the fiberboard is heated, ensuring the uniformity of heating.

[0034] It should be further explained that a first heat-conducting plate 20 is welded and fixed to the lower end of the hot pressing mold 12. A first bent pipe 21 is embedded and fixed on the first heat-conducting plate 20. A first cold water inlet and a first cold water outlet are respectively provided at both ends of the first bent pipe 21. By passing cold water into the first bent pipe 21, cold water circulation can be realized, thereby cooling the hot pressing mold 12 with water.

[0035] It should be further explained that a second heat-conducting plate 30 is welded and fixed to the upper end of the hot press plate 16. A second bent pipe 31 is embedded and fixed in the second heat-conducting plate 30. A second cold water inlet and a second cold water outlet are respectively provided at both ends of the second bent pipe 31. By passing cold water into the second bent pipe 31, cold water circulation can be realized, thereby cooling the hot press mold 12 with water.

[0036] It should be further noted that both the first heat-conducting plate 20 and the second heat-conducting plate 30 are made of aluminum alloy, which has good connection strength and good thermal conductivity.

[0037] It should be further explained that a rod sleeve 40 is provided through the bottom of the plate groove 13, and the rod sleeve 40 passes through the first heat-conducting plate 20. A top rod 41 slides through the inside of the rod sleeve 40. The rod sleeve 40 is staggered with the first bend tube 21 and the first electric heating tube 17 respectively. There are at least four top rods 41, which are symmetrically distributed in pairs. By pushing out from multiple positions, the output of the fiberboard after shaping can be guaranteed to be stable.

[0038] It should be further noted that a second cylinder 42 is also fixed to the upper end of the base 10. The second cylinder 42 has a second piston rod for extension and retraction inside. The upper end of the second piston rod is fixedly assembled with the lower end of the push rod 41 by screws.

[0039] Working method: When hot pressing of fiberboard is required, the fiberboard material is placed into the plate groove 13. Then, the power supply of the first heating tube 17 and the second heating tube 18 is turned on respectively, so that the heating tubes at the two positions can be heated. Then, the first piston rod of the first cylinder 15 is pushed forward, which can drive the hot pressing plate 16 to move downward and enter the plate groove 13 to hot press the fiberboard material into shape.

[0040] After hot pressing for a certain period of time, the fiberboard is formed. Then, low-temperature water is introduced into the inside of the first bend pipe 21 and the second bend pipe 31 respectively to realize cold water circulation, thereby reducing the stability of the mold 12 and the hot pressing plate 16 under hot pressing, and thus cooling and shaping the fiberboard.

[0041] During the unloading process, the hot press plate 16 is moved upward to open, and then the second piston rod of the second cylinder 42 is pushed forward, so that the push rod 41 can extend upward within the rod sleeve 40, thereby ejecting the shaped fiberboard.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
