Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing and drying, in particular to an integrated hot pressing and drying machine for composite panels. Background Art

[0002] Composite panels are made of different materials layered together to create different functions. Composite panels are generally classified into steel doors, metal composite panels, wood composite panels, color-coated steel composite panels, and rock wool composite panels. Common lamination methods include explosive lamination, explosive rolling lamination, and rolling lamination. Composite materials can be categorized into composite plates, composite pipes, and composite rods. They are primarily used in industries such as corrosion protection, pressure vessel manufacturing, power construction, petrochemicals, pharmaceuticals, light industry, and the automotive industry.

[0003] However, in the prior art, when composite boards are manufactured, the boards are usually pressed using a hot press. When the existing hot press needs to fill adhesive between each layer of the board and then perform a pressing process, the existing process usually involves hot pressing the board and then drying the board, which requires multiple steps and is time-consuming and labor-intensive. In addition, the existing hot press can only press one composite board at a time, and the processing rate is low. Utility Model Content

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: an integrated composite board hot pressing and drying machine, comprising: a heating box; a box door, the outer wall of the box door is rotatably connected to the outer wall of the heating box; a hydraulic press, the outer wall of the hydraulic press is fixedly connected to the top of the heating box; a pressing mechanism, the bottom end of the pressing mechanism is fixedly connected to the inner wall of the heating box; the pressing mechanism includes a lower pressing plate, the bottom end of the lower pressing plate is provided with a heating plate, the inner wall of the lower pressing plate is fixedly connected with a block, the four corners of the inner wall of the heating plate are fixedly connected with a fixed cylinder, the inner wall of the fixed cylinder is provided with a sliding groove, the inner wall of the fixed cylinder is slidably connected with a connecting rod, and the bottom end of the connecting rod is fixedly connected with a push spring.

[0005] Preferably, an exhaust pipe is fixedly connected to the top of the heating box, heating wires are fixedly connected to both ends of the inner wall of the heating box, and a hot air blower is symmetrically fixedly connected to the bottom end of the inner wall of the heating box. The heating wires at both ends of the heating box dry the hot-pressed composite board, and the hot air blower at the bottom is activated to blow the hot air inside the heating box, so that the hot air circulates inside, making it dry more thoroughly and evenly.

[0006] Preferably, the inner wall of the lower pressing plate is slidably connected to the outer wall of the fixed cylinder, the outer wall of the clamping block is slidably connected to the inner wall of the sliding groove, and the outer wall of the clamping block is fixedly connected to the outer wall of the connecting rod. By connecting the clamping block on the lower pressing plate and the connecting rod, when the top lower pressing plate moves downward, the connecting rod drives the clamping block to slide in the sliding groove, thereby causing the two lower pressing plates at the bottom to move downward to complete the hot pressing.

[0007] Preferably, the bottom end of the fixed cylinder is fixedly connected to the inner wall of the heating box, and the end of the push spring away from the connecting rod is fixedly connected to the inner wall of the fixed cylinder. The hydraulic press drives the lower pressure rod to move upward, no longer pressing the adjustment rod downward. At this time, the push spring pushes the connecting rod to move back to its original position, causing the lower pressure plate to move upward, and the hot-pressed composite sheet can be removed.

[0008] Preferably, the top of the lower pressure plate is fixedly connected to a limit cylinder, the inner wall of which is threadedly connected to an adjustment rod, and the top of the adjustment rod is provided with a lower pressure rod. The top of the lower pressure rod is fixedly connected to the output end of the hydraulic press, and the outer wall of the lower pressure rod contacts the top of the adjustment rod. The hydraulic press drives the lower pressure rod to move a fixed distance. By rotating the adjustment rod, the lower pressure rod moves within the threaded limit cylinder, adjusting the distance between the lower pressure rod and the lower pressure rod, thereby adjusting the hot pressing distance.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The utility model sets a pressing mechanism. According to the thickness of the composite board required for hot pressing, the distance between the adjusting rod and the lower pressing rod is adjusted by rotating the adjusting rod. At this time, the box door is closed, and the block on the lower pressing plate is connected with the connecting rod. When the lower pressing plate at the top moves downward, the two lower pressing plates at the bottom move downward to complete the hot pressing. In this way, multiple composite boards can be hot pressed, reducing processing steps and improving usage efficiency.

[0011] 2. The utility model dries the hot-pressed composite board by setting heating wires at both ends of the heating box for preliminary drying, and starts the hot air blower at the bottom to blow the hot air in the heating box, so that the hot air circulates inside and dries it more fully and evenly, opens the exhaust pipe at the top, and discharges the water vapor in the box outwards through the exhaust pipe due to the difference in internal and external pressures, thereby keeping the interior of the box dry.
