Description

Technical Field

[0001] The present invention relates to a production process and a hot pressing forming device thereof, in particular to an environmentally friendly glass fiber board production process and a hot pressing forming device thereof, belonging to the technical field of board processing. Background Art

[0002] Glass fiber boards have diverse surface decoration styles, which can meet various decoration requirements. Their surface decoration conforms well to the modern public aesthetic, and they are easy to install quickly. Therefore, they are widely used in the decoration of places such as hotels and homes. Especially in hotel decoration, glass fiber boards can enhance the overall decoration grade and create a modern, fashionable, and elegant atmosphere.

[0003] The production process of glass fiber boards usually involves making a panel from a thermoplastic material and then fixing it on both sides of the panel by bonding or hot pressing. The strength and flexural strength are relatively low. The processing of glass fiber boards is achieved through a composite machine production line. The traditional composite machine production line consists of an inner machine and a heat-insulating outer shell. The inner machine is arranged inside the heat-insulating outer shell. Components such as a hydraulic main cylinder, a base, a lower heating plate, and a punch are sequentially arranged directly above the lower base of the inner machine. Therefore, after hot pressing, the machine needs to be opened for demolding. On the one hand, this will cause a large amount of heat loss, and on the other hand, demolding will also waste a lot of time, wasting energy and unable to guarantee the efficiency of hot pressing.

[0004] Therefore, it is urgent to improve the hot pressing forming device of inkstone boards to solve the above problems. Summary of the Invention

The blower support plate is arranged directly above the driving gear, and a plurality of blowers are evenly distributed on the blower support plate.

[0032] Preferably, both the vertical driving rod and the horizontal driving rod are of U-shaped structure, and the vertical driving rod and the horizontal driving rod are cross-arranged.

[0033] Preferably, a chassis shell is fixedly arranged on the outer side surface of the lower base. Both the upper base and the lower base are arranged inside the chassis shell.

[0044] A forming method of a hot pressing forming device for an antibacterial and energy-saving resin ink rock plate comprises the following steps:

[0045] Step 1: Raw material preparation, select high-quality resin raw materials, add appropriate amounts of antibacterial agents and fillers, mix them evenly and put them between the hot pressing groove and the movable module;

[0046] Step 2: Hot pressing forming, after putting the mixed raw materials in, start the main hydraulic cylinder to push the upper base downward. During the process of pushing the upper base, the arc-shaped demolding plate slides into the interior of the chassis housing. Start the upper heating strip and the lower heating strip to uniformly heat the punch and the movable module. After the movable module enters the interior of the lower base, uniformly press the plate;

[0047] Step 3: Cooling and demolding, after the hot pressing forming is completed, turn off the upper heating strip and the lower heating strip. The upper base rises and the movable base is pushed out of the lower base. The plate cools in the hot pressing groove.

The purified air is directly blown onto the plate on the arc-shaped demolding plate to achieve the purpose of accelerating the cooling of the plate.

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

[0050] 1. Due to certain ingredients, the fiber board has good strength, with good flexural strength and compressive strength, and relatively high wear resistance and bonding strength. When loading or unloading materials, the upper base moves upward through the main hydraulic cylinder, the vertical driving rod drives the first gear to rotate, and at the same time, the movable base is pushed outward through the horizontal driving rod. Therefore, when the movable base extends out of the lower base, it is convenient for loading and unloading materials. During hot pressing, the upper base moves downward through the main hydraulic cylinder, and the vertical driving rod drives the movable base to move in the opposite direction. During the process of the upper base gradually approaching the movable base, the raw materials also gradually approach the punch. Start the auxiliary cylinder on the punch to hot press the raw materials, so the hot pressing efficiency 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

[0093] Example 2:

[0094] This example is basically the same as Example 1, except that: A production process of an environmentally friendly glass fiber board, the environmentally friendly glass fiber board is composed of the following raw materials:

[0105] Performance testing, the fiber board was tested and the average water mark height was calculated. The test results are as follows

[0106] As shown in Table 1;

[0107]

[0108] It can be seen from the test results in Table 1 that the fiber board made by the present invention has good strength, good flexural strength and compressive strength, and at the same time has relatively high wear resistance and bonding strength;

[0109] In addition, the present device includes an upper base 1 and a lower base 2 disposed below the upper base 1. A movable base 3 is horizontally slidably disposed inside the lower base 2. A hydraulic main cylinder 108 is fixedly disposed on the upper side of the upper base 1. The hydraulic main cylinder 108 is used to vertically push the upper base 1. The upper base 1 corresponds to the lower base 2. By driving the upper base 1 and the lower base 2 to engage through the hydraulic main cylinder 108, hot pressing can be achieved. The structure is simple and the production cost is low. The bottom of the upper base 1 is fixedly connected with a punch 109 through a secondary cylinder 104. A hot pressing groove 301 is formed on the movable base 3. A movable module 302 is vertically slidably disposed inside the hot pressing groove 301. The hot pressing groove 301 corresponds to the punch 109. When driving the upper base 1 through the hydraulic main cylinder 108, the punch 109 at the bottom of the upper base 1 is squeezed into the inside of the hot pressing groove 301 under the action of the secondary cylinder 104 and approaches the movable module 302. Therefore, only by placing the raw material inside the hot pressing groove 301 can hot pressing be achieved;

[0110] The present invention adopts the method of pushing the movable base 3 by the upper base 1, 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;

[0114] In order to achieve rapid demoulding, an arc-shaped demoulding plate 4 is fixedly provided on the bottom side surface inside the lower base 2, and a demoulding slope 401 corresponding to the movable module 302 is provided on the arc-shaped demoulding plate 4, and the movable module 302 is abutted against the upper side surface of the demoulding slope 401. 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] Meanwhile, as the movable base 3 moves outward, symmetrically distributed movable base guide bars 201 are provided on the inner side of the lower base 2. Movable base guide grooves 305 corresponding to the movable base guide bars 201 are formed on the movable base 3. The movable base guide bars 201 are slidably arranged inside the movable base guide grooves 305. The movable base guide bars 201 on the lower base 2 can slide inside the movable base guide grooves 305 of the movable base 3, thus ensuring the stability of the sliding of the movable base 3. Workers can directly remove the hot-pressed plates from the movable base 3, greatly improving the demoulding and material-taking efficiency. Of course, after the material-taking is completed, the raw materials can be directly placed inside the hot-pressing groove 301 for the next hot-pressing directly, greatly improving the hot-pressing efficiency;

[0116] In addition, the arc-shaped demoulding plate 4 extends to the outside of the lower base 2. When the movable module 302 slides onto the demoulding slope 401, the height of the movable module 302 is lower than the depth of the hot-pressing groove 301. The movable module 302 is slidably arranged inside the hot-pressing groove 301, and the upper side surface of the movable module 302 is lower than the upper side surface of the hot-pressing groove 301. That is to say, the raw materials can be directly placed between the hot-pressing groove 301 and the movable module 302, facilitating hot-pressing and material-taking;

[0117] The entire hot-pressing process is completed inside the chassis housing 9, ensuring that heat will not be dissipated. At the same time, through this device, the cyclic operations of feeding, hot-pressing, demoulding, and feeding can be completed in sequence, realizing the synchronous progress of the hot-pressing process, saving a large amount of resources and greatly improving the processing efficiency;

[0118] To ensure the temperature during hot-pressing, further, as shown in Figure 4 、 Figure 5 and Figure 7 , the chassis housing 9 is fixedly arranged on the outer side surface of the lower base 2. The upper base 1 and the lower base 2 are both arranged inside the chassis housing 9. The upper base 1 and the lower base 2 are both arranged inside the chassis housing 9 and hot-press the plates without manual intervention, ensuring a high enough temperature during hot-pressing. A vertical sliding bin 901 corresponding to the vertical driving rod 102 is arranged at the bottom of the chassis housing 9. The vertical driving rod 102 is slidably arranged inside the vertical sliding bin 901, ensuring enough movement space for the vertical driving rod 102. A horizontal sliding bin 902 corresponding to the horizontal driving rod 303 is fixedly arranged on one side of the chassis housing 9. The horizontal driving rod 303 is slidably arranged inside the horizontal sliding bin 902, ensuring enough movement space for the horizontal driving rod 303. At the same time, the vertical driving rod 102 and the horizontal driving rod 303 are arranged inside the chassis housing 9, which also helps to reduce heat loss;

[0119] On one side of the chassis housing 9 corresponding to the arc-shaped stripping plate 4, there is a discharge port 904. The movable base 3 is slidably arranged inside the discharge port 904. During the entire hot pressing process, when taking and loading materials, the movable base 3 slides out from the discharge port 904, and the hot pressing is carried out inside the chassis housing 9 to reduce heat loss. At the same time, when the movable base 3 extends out from the discharge port 904, it also helps to dissipate heat from the plate during the demolding process;

[0120] At the same time, as Figure 2 and Figure 3 shown, in order to increase the temperature inside the chassis housing 9, a upper base heating groove 105 is provided in the middle of the upper base 1. An upper heating strip 106 is fixedly arranged inside the upper base heating groove 105. The upper heating strip 106 is used to heat the punch 109. A arc-shaped plate heating groove 402 is provided in the middle of the arc-shaped stripping plate 4. A lower heating strip 403 is fixedly arranged inside the arc-shaped plate heating groove 402. The lower heating strip 403 is used to heat the movable module 302. An upper heating strip 106 for heating the punch 109 is arranged in the middle of the upper base 1, and a lower heating strip 403 for heating the movable module 302 is arranged on the arc-shaped stripping plate 4. Therefore, it can ensure the temperature inside the chassis housing 9 and the temperature required for hot pressing;

[0121] In addition, one side of the lower base 2 is connected with symmetrically distributed L-shaped support arms 202. A blower support plate 203 is fixedly arranged between the two L-shaped support arms 202. The blower support plate 203 is arranged directly above the driving gear 6. A number of evenly distributed blowers 204 are arranged on the blower support plate 203. There are blowers 204 fixed on the lower base 2 inside the chassis housing 9. After starting the blowers 204, it can stir the hot air flow inside the chassis housing 9 to make the temperature distribution more uniform and improve the quality of hot pressing.

[0122] Furthermore, as Figure 5 、 Figure 6 and Figure 9 shown, harmful gases will be generated during the hot pressing process. One side of the outer surface of the chassis housing 9 close to the driving gear 6 is communicated with an exhaust gas treatment mechanism 7. The exhaust gas treatment mechanism 7 includes an air extraction box 701, a liquid storage box 702 and a purification box 703 which are communicated with each other. The harmful gases generated inside the chassis housing 9 are sequentially sucked into the liquid storage box 702 and the purification box 703 by the air extraction box 701 for purification. An exhaust fan 707 is fixedly arranged inside the air extraction box 701 and is communicated with the inside of the chassis housing 9;

[0123] First, the air inside the chassis housing 9 is extracted by the air extractor 707 inside the air extraction box 701. The air extraction box 701 is connected to the liquid storage tank 702 through the air extraction pipe 705. The inside of the liquid storage tank 702 is filled with calcium hydroxide solution. The acidic gas generated by hot pressing is absorbed by the alkaline calcium hydroxide after entering the inside of the liquid storage tank 702, completing the primary purification;

[0124] Then, the liquid storage tank 702 is connected to the purification box 703 through the connecting pipe 706. A purification chamber 708 is provided inside the purification box 703, and a purification component 8 is arranged inside the purification chamber 708. The purification component 8 includes a first partition net 801, a sponge layer 802, an activated carbon layer 803, and a second partition net 804. The air after primary purification enters the inside of the purification box 703, and the air is purified again through the sponge layer 802 and the activated carbon layer 803 to adsorb harmful gases and impurities in the waste gas;

[0125] Finally, an exhaust pipe 704 is connected to the purification box 703. The exhaust pipe 704 extends to the upper side of the arc-shaped demolding plate 4. The purified air is discharged to the upper side of the movable base 3 through the exhaust pipe 704, and the plate is cooled, and at the same time, the dust and impurities on the movable base 3 can be cleaned. The structure is simple, and the efficiency of hot pressing is greatly improved.

[0126] Furthermore, as Figure 1 、 Figure 4 and Figure 6 shown, assembly grooves 905 are provided on both side surfaces of the chassis housing 9. The assembly grooves 905 are fixedly connected to the lower base 2 through bolts. A fixing plate 906 is fixedly arranged on the outer side surface of the chassis housing 9.

A viewing window groove 903 is provided on the chassis housing 9 above the assembly groove 905. A viewing window 10 is fixedly arranged inside the viewing window groove 903. It is convenient to observe the hot pressing situation inside the chassis housing 9 through the viewing window 10, improving the convenience of use;

[0127] A support frame 11 is fixedly arranged on the outer side surface of the chassis housing 9. The upper end of the hydraulic main cylinder 108 is fixedly connected to the support frame 11 through the cylinder connecting plate 13. The bottom of the support frame 11 is fixedly connected to the bottom side surface of the lower base 2 through the support column 12. The hydraulic main cylinder 108 is fixedly connected to the support frame 11 through the cylinder connecting plate 13. The upper base 1 is fixedly connected to the support frame 11 through the support column 12, improving the overall stability of the device;

[0128] The upper side of the upper base 1 is connected with an upper base connecting plate 107. The output end of the hydraulic main cylinder 108 is fixedly connected to the upper side of the upper base connecting plate 107. The upper side of the upper base 1 is fixedly provided with a vertical driving rod connecting arm 101. The vertical driving rod 102 is fixedly connected to the upper base 1 through the vertical driving rod connecting arm 101. The vertical driving rod 102 is fixedly connected to the upper base 1 through the vertical driving rod connecting arm 101, enhancing the structural strength of the vertical driving rod 102. The upper base 1 is fixedly connected to the hydraulic main cylinder 108 through the upper base connecting plate 107, enhancing the structural strength of the upper base 1;

[0129] Both the vertical driving rod 102 and the horizontal driving rod 303 are U-shaped structures, and the vertical driving rod 102 and the horizontal driving rod 303 are cross-arranged. The cross-arrangement of the vertical driving rod 102 and the horizontal driving rod 303 plays a role in limiting and guiding, enhancing the stability of the device operation.

[0130] As Figures 1-9 shown, the forming method of the antibacterial and energy-saving resin inkstone plate hot pressing forming device provided in this embodiment includes the following steps:

[0131] Step 1: Raw material preparation. Select high-quality resin raw materials, add appropriate amounts of antibacterial agents and fillers, mix them evenly, and then put them between the hot pressing groove 301 and the movable module 302;

[0132] Step 2: Hot pressing forming. After putting the mixed raw materials in, start the hydraulic main cylinder 108 to push the upper base 1 downward. During the process of pushing the upper base 1, the arc-shaped demolding plate 4 slides into the interior of the chassis housing 9. Start the upper heating strip 106 and the lower heating strip 403 to uniformly heat the punch 109 and the movable module 302. After the movable module 302 enters the interior of the lower base 2, uniformly press the plate;

[0133] Step 3: Cooling and demolding. After the hot pressing forming is completed, turn off the upper heating strip 106 and the lower heating strip 403. The upper base 1 rises and the movable base 3 is pushed out of the lower base 2. The plate cools in the hot pressing groove 301. As the movable base 3 is continuously pushed out, the movable module 302 contacts the demolding slope 401, achieving the purpose of rapid demolding;

[0134] Step 4: Exhaust gas treatment. Start the exhaust gas treatment mechanism 7 to absorb the exhaust gas inside the chassis housing 9, absorb it through the liquid storage tank 702, and then pass through the purification tank 703, and be purified under the action of the purification component 8. The purified air is directly blown onto the plate on the arc-shaped demolding plate 4, achieving the purpose of accelerating the cooling of the plate.
