Their surface decoration is very consistent with the modern public aesthetic and is easy and quick to install. Therefore, they are widely used in the decoration of hotels, homes and other places. Especially in hotel decoration, fiberglass sheets can enhance the overall decoration level and create a modern, fashionable and elegant atmosphere.

[0003] The production process of fiberglass sheets is usually to make thermoplastic materials into panels, and then fix them on both sides of the panels by bonding or hot pressing. The strength and flexural strength are low. The processing of fiberglass sheets is achieved through a composite machine production line. The traditional composite machine production line consists of an inner machine and an insulating outer shell. The inner machine is arranged in the insulating outer shell. The hydraulic main cylinder, base, lower heating plate and punch and other components are arranged in sequence directly above the lower base of the inner machine. Therefore, after the hot pressing is completed, the machine needs to be opened for demolding. On the one hand, it will cause a large amount of heat loss, and on the other hand, demolding will also waste a lot of time, which not only wastes energy but also fails to ensure the efficiency of hot pressing.

[0049] The present invention has at least the following beneficial effects:

[0050] 1. Through certain ingredients, the fiber board has good strength, good flexural strength and compressive strength, and high wear resistance and bonding strength. When loading or taking materials, the upper base moves upward through the hydraulic main cylinder, and the vertical drive rod drives the first gear to rotate. At the same time, the movable base is pushed outward by the horizontal drive rod. Therefore, when the movable base extends out of the lower base, it is convenient for loading and taking materials. During hot pressing, the upper base moves downward through the hydraulic main cylinder, and the vertical drive rod drives the movable base to move in the opposite direction. In the process of the upper base gradually approaching the movable base, the raw material also gradually approaches the punch. When the auxiliary cylinder on the starting punch is used to hot press the raw material, the efficiency of hot pressing can be improved.

[0051] 2. An arc-shaped demolding plate is arranged at the bottom of the movable module. Therefore, when the movable base moves horizontally, the movable module will move upward. As the movable base continues to move outward, the hot-pressed sheet will gradually be ejected from the hot-pressing groove by the movable module. Therefore, after the hot-pressing is completed, as the upper base rises, the hot-pressed sheet will gradually leave the hot-pressing groove and achieve the purpose of demolding.

[0052] 3. During the whole process of hot pressing, the movable base slides out from the discharge port when taking and loading materials, and the hot pressing is carried out inside the chassis shell to reduce heat loss. At the same time, when the movable base extends out from the discharge port, it also helps to dissipate heat for the sheet during the demoulding process.

[0053] 4. An upper heating bar for heating the punch is arranged in the middle of the upper base, and a lower heating bar for heating the movable module is arranged on the arc-shaped stripping plate, so as to ensure the temperature inside the chassis shell and the temperature required for hot pressing. A blower fixed on the lower base is arranged inside the chassis shell. After starting the blower, the hot air flow inside the chassis shell can be stirred, so that the temperature distribution is more uniform, thereby improving the quality of hot pressing.

[0054] 5. The acidic gas generated by hot pressing is absorbed by alkaline calcium hydroxide after entering the liquid storage tank, completing the initial purification. The air after the initial purification enters the interior of the purification box, and is purified again by the sponge layer and the activated carbon layer to adsorb harmful gases and impurities in the exhaust gas. The purified air is discharged to the upper side of the movable base through the exhaust pipe, and the heat is dissipated to the plate. At the same time, the dust and impurities on the movable base can be cleaned. The structure is simple and the efficiency of hot pressing is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the upper base 1 is fixed by the auxiliary oil cylinder 104. A convex die 109 is fixedly connected, a hot pressing groove 301 is opened on the movable base 3, and a movable module 302 is vertically slidably arranged inside the hot pressing groove 301. The hot pressing groove 301 corresponds to the convex die 109.

Therefore, it is only necessary to place the raw material inside the hot pressing groove 301 to achieve hot pressing;

[0110] The present invention adopts the method that the upper base 1 pushes the movable base 3, specifically:

[0111] A driving gear 6 is rotatably provided on one side of the lower base 2, and the driving gear 6 includes a first gear 601 and a second gear 602 that are fixedly connected. The driving gear 6 is fixedly connected to one side of the lower base 2 through a gear support arm 603. The driving gear 6 is fixedly provided on the lower base 2 through the gear support arm 603. The first gear 601 and the second gear 602 on the driving gear 6 are rotatably provided on the gear support arm 603. A vertical driving rod 102 is fixedly provided at one end of the upper base 1, and a gear meshing and connected with the second gear 602 is fixedly provided on the vertical driving rod 102. A vertical driving rack 103, a horizontal driving rod 303 is fixedly provided at one end of the movable base 3, and a horizontal driving rack 304 meshingly connected with the first gear 601 is fixedly provided on the horizontal driving rod 303, wherein when the upper base 1 moves vertically, the movable base 3 moves horizontally, and when the upper base 1 is pushed downward by the hydraulic main oil cylinder 108, the vertical driving rod 102 on the upper base 1 drives the first gear 601 on the driving gear 6 to rotate, and while the first gear 601 rotates, the horizontal driving rod 303 on the movable base 3 is driven to move horizontally through the second gear 602;

[0112] When loading or removing materials, the upper base 1 moves upward through the hydraulic main cylinder 108, the vertical driving rod 102 drives the first gear 601 to rotate, and at the same time the movable base 3 is pushed outward through the horizontal driving rod 303, so when the movable base 3 extends out of the lower base 2, it is convenient for loading and removing materials;

[0113] During hot pressing, the upper base 1 moves downward through the hydraulic main cylinder 108, and the vertical driving rod 102 drives the movable base 3 to move in the opposite direction. In the process of the upper base 1 gradually approaching the movable base 3, the raw material also gradually approaches the punch 109, and the auxiliary cylinder 104 on the punch 109 is started to hot press the raw material, so hot pressing can be performed synchronously;

An arc-shaped demoulding plate 4 is provided at the bottom of the movable module 302, so that when the movable base 3 moves horizontally, the movable module 302 will move upward. As the movable base 3 continues to move outward, the hot-pressed plate will gradually be ejected from the hot-pressing groove 301 by the movable module 302. Therefore, after the hot-pressing is completed, as the upper base 1 rises, the hot-pressed plate will gradually separate from the hot-pressing groove 301 and achieve the purpose of demoulding;

[0115] At the same time, as the movable base 3 moves outward, the inner side surface of the lower base 2 is provided with symmetrically distributed movable base guide strips 201, and the movable base 3 is provided with movable base guide grooves 305 corresponding to the movable base guide strips 201. The movable base guide strips 201 are slidably arranged inside the movable base guide grooves 305. The movable base guide strips 201 on the lower base 2 can slide inside the movable base guide grooves 305 of the movable base 3, thereby ensuring the sliding stability of the movable base 3.
