Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic septic tank forming and processing, and specifically, to an environmentally friendly glass fiber reinforced plastic septic tank forming and processing equipment. Background Art

[0002] FRP septic tank refers to a device made of synthetic resin as the matrix and glass fiber reinforced material specially used for treating domestic sewage. FRP septic tank is a domestic sewage purification treatment equipment for civil buildings such as industrial enterprise living quarters and urban residential quarters. FRP septic tank temporarily stores excrement and makes it decompose initially in the tank to reduce the solid content in the discharged sewage. FRP septic tank is a composite material product actively promoted by the country. It has the advantages of light weight, high strength, good toughness, corrosion resistance, bright colors, and mirror finish.

[0003] FRP septic tanks are usually formed by compression molding. The raw material sheets are cut according to the molding amount and fed between the dies. The dies include an upper concave die and a lower punch. The raw material sheet is placed on the lower punch. The press heats the die and drives the upper concave die down to extrude the sheet. As the temperature of the die rises, the sheet softens and flows to fill the cavity. After reaching the solidification temperature, the sheet solidifies and forms in the cavity. Finally, the die is cooled and demolded to complete the molding of the FRP septic tank. However, in the actual production process, it is currently necessary to manually place the raw material sheet on the bottom die. After cooling, the molded product is usually removed from the lower punch manually. The die needs to be preheated before loading, and the surface of the die still has a certain temperature after cooling. It is easy to cause burns to the hands during loading and unloading, and the hands are between the upper concave die and the lower punch. The equipment is heavy and there are certain safety hazards. Therefore, we propose an environmentally friendly FRP septic tank molding and processing equipment, which can realize automatic loading and unloading, reduce manual participation, and reduce safety hazards.

[0034] The working principle and beneficial effects of the present invention are:

[0035] 1. In the present invention, the rotation of the driving gear can drive the driven rack 1 and the driven rack 2 to move relative to each other. After the vacuum suction cup descends and sucks the FRP septic tank on the lower mold, the driving frame drives the vacuum suction cup and the FRP septic tank to rise, and the driving gear drives the unloading frame away from the lower mold, and the loading frame moves to between the lower mold and the upper mold. The raw material sheet placed on the blanking plate can be dumped onto the lower mold by the downward rotation of the blanking plate, completing the unloading and loading, reducing manual participation, and no manual loading and unloading operations are required between the upper mold and the lower mold, reducing safety hazards.

In the present invention, by moving the heater to contact the heat transfer bin, heat can be transferred to the cavity of the upper mold or the lower mold through the heat transfer bin and the heat transfer plate, and the raw material sheet is heated to soften it and fill the cavity between the upper mold and the lower mold to form a fiberglass septic tank. After a period of time, the heater is away from the heat transfer bin, and cold water is transported to the inside of the cold water cavity through the cold water pipe to cool the heat transfer bin, thereby cooling the cavity of the upper mold and the lower mold. When heating again, the drain pipe supplies air to the inside of the cold water cavity, and the cold water in the cold water cavity is discharged through the cold water pipe, thereby reducing the influence of cold water on heating, and at the same time reducing the reduction in cooling effect caused by the temperature rise of cold water in the subsequent cooling process, thereby ensuring the heating and cooling effects.

[0037] 3. In the present invention, air is supplied to the interior of the demoulding cavity through the air blowing pipe, the pressure inside the demoulding cavity is increased, and the push plate is pushed out from the interior of the demoulding tube. The push plate pushes the formed FRP septic tank away from the upper mold and the lower mold, thereby realizing the demoulding of the FRP septic tank and facilitating the subsequent unloading of the FRP septic tank by the vacuum suction cup and the clamping plate.

[0038] 4. Therefore, compared with the molding processing equipment in the prior art, the present invention realizes the alternating movement of the loading frame and the unloading frame through the cooperation of the driving gear, the driven rack one and the driven rack two, and the vacuum suction cup and the clamping plate clamp and attract the formed FRP septic tank to unload the FRP septic tank.

The upper mold and the lower mold are heated and cooled by the heater and cold water. The cold water is discharged from the cold water cavity through the movement of the heater and the drain pipe, which can reduce the interference between heating and cooling. At the same time, the push plate is driven by the air pipe to push the formed FRP septic tank away from the upper mold and the lower mold to facilitate subsequent unloading.

[0061] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] like Figures 1 to 11 As shown, this embodiment proposes an environmentally friendly glass fiber reinforced plastic septic tank forming and processing equipment, including a press, an upper mold 1 and a lower mold 2, the press includes a top seat 101, a base 102, a guide column 103 and a hydraulic cylinder 104, the lower mold 2 is arranged on the base 102, the hydraulic cylinder 104 is arranged on the top seat 101, the upper mold 1 is arranged at the output end of the hydraulic cylinder 104, the upper mold 1 and the guide column 103 are in sliding cooperation, and also include a heater 3, a cooling mechanism, a feeding mechanism and a unloading mechanism. Compared with the forming and processing equipment in the prior art, the present invention realizes the feeding frame 301 and the unloading mechanism through the cooperation of the driving gear 503, the driven rack 1 504 and the driven rack 2 505. The rack 401 moves alternately, and the vacuum suction cup 402 and the clamping plate 801 clamp and attract the formed FRP septic tank to unload the FRP septic tank. The raw material sheet can be dropped onto the lower mold 2 by the rotation of the blanking plate 302 to realize loading, which reduces manual participation and thus reduces potential safety hazards. The upper mold 1 and the lower mold 2 are heated and cooled by the heater 3 and cold water. The cold water is discharged from the cold water chamber 204 by the movement of the heater 3 and the drain pipe 701, which can reduce the interference between heating and cooling. At the same time, the push plate 603 is driven by the air pipe 601 to push the formed FRP septic tank away from the upper mold 1 and the lower mold 2 to facilitate subsequent unloading.

[0063] like Figures 6 to 9 As shown, a heating cavity is provided on the upper mold 1 and the lower mold 2, and a heater 3 is movably arranged inside the heating cavity. An electric cylinder 4 is provided on the upper mold 1 and the lower mold 2, and the heater 3 is arranged at the output end of the electric cylinder 4. The heater 3 can be driven to move by the electric cylinder 4, and the upper mold 1 and the lower mold 2 can be heated by the heater 3, so as to heat the raw material sheet between the upper mold 1 and the lower mold 2, so that it softens and flows to fill the upper mold 1 and the lower mold 2 to be formed into a glass fiber reinforced plastic septic tank.

[0064] like Figures 1 to 11 As shown, the cooling mechanism is used to cool the upper mold 1 and the lower mold 2, and the cooling mechanism includes a heat conduction chamber 201, a heat conduction plate 202 and a cold water pipe 203. There are two heat conduction chambers 201, which are respectively arranged inside the upper mold 1 and the lower mold 2, and there are multiple heat conduction plates 202, which are arranged inside the heat conduction chamber 201. A plurality of cold water cavities 204 are isolated inside the heat conduction chamber 201. There are two cold water pipes 203, which are respectively arranged inside the upper mold 1 and the lower mold 2. The cold water cavity 204 is connected to the cold water pipe 203, and the cold water pipe 203 is connected to an external refrigeration device or a faucet. The external refrigeration device or the faucet transports cold water to the cold water pipe 20 3, cold water flows into the cold water cavity 204 through the cold water pipe 203 to cool the upper mold 1 or the lower mold 2. The cold water pipe 203 is connected with a water outlet pipe, which can be connected to an external refrigeration device to realize cold water recycling. The discharged water can also be used for other purposes or discharged to a certain place for storage. The heat conduction plate 202 and the heat conduction bin 201 are both made of materials with good thermal conductivity. The heater 3 is in contact with the heat conduction bin 201, and the heat can be transferred to the cavity of the upper mold 1 or the lower mold 2 through the heat conduction bin 201 and the heat conduction plate 202. The cold water cools the cavity of the upper mold 1 or the lower mold 2 through the heat conduction bin 201 and the heat conduction plate 202, so that the formed fiberglass reinforced plastic septic tank is cooled and solidified, which is convenient for subsequent material unloading.

[0065] like Figure 4As shown, the loading mechanism is used to place the raw material sheet on the lower mold 2. The loading mechanism includes a loading frame 301 and a blanking plate 302. The loading frame 301 is movably arranged between the upper mold 1 and the lower mold 2. Two blanking plates 302 are provided. The blanking plates 302 are rotatably arranged inside the loading frame 301. The ends of the two blanking plates 302 that are close to each other are free ends, and the ends of the two blanking plates 302 that are away from each other are rotatably arranged on the loading frame 301 through a rotating shaft. Two motors 303 are provided on the loading frame 301. The two rotating shafts are respectively arranged at the output ends of the corresponding motors 303. The rotating shafts and the blanking plates 302 can be driven to rotate by the motors 303. The two blanking plates 302 rotate to a horizontal state to close the loading frame 301. The raw material sheet is placed on the blanking plates 302. After the blanking plates 302 move to the top of the lower mold 2, the blanking plates 302 rotate downward to make the raw material sheet fall onto the lower mold 2. On, the loading of the raw material sheet is completed. The raw material sheet is preheated before molding. The preheated raw material sheet has a certain adhesion, and the raw material sheet is folded into a narrower sheet. The top of the lower mold 2 has a certain width, and the surface of the lower mold 2 is adapted to the surface shape of the fiberglass reinforced plastic septic tank, and there are certain undulations, which can increase the resistance between the raw material sheet and the blanking plate 302. At the same time, a lubricant can be applied to the surface of the blanking plate 302 to allow the raw material sheet to slide smoothly. The two blanking plates 302 are rotated downward to a V shape, that is, when the distance between the bottom ends of the two blanking plates 302 is less than the width of the raw material sheet, the raw material sheet can slide smoothly. At this time, the distance between the bottom ends of the two blanking plates 302 is small, and the raw material sheet can be limited to fall on the top of the lower mold 2. When the raw material sheet falls on the top of the lower mold 2, the preheated raw material sheet is stably adhered to the surface of the lower mold 2 and will not slip.

[0066] like Figure 5As shown, the unloading mechanism is used to remove the formed FRP septic tank from the lower mold 2. The unloading mechanism includes an unloading rack 401 and a vacuum suction cup 402. The unloading rack 401 can be lifted and movably arranged between the upper mold 1 and the lower mold 2. The vacuum suction cup 402 can be lifted and arranged on the unloading rack 401. The unloading rack 401 is provided with an electric cylinder 403. The vacuum suction cup 402 is arranged at the output end of the electric cylinder 403. The unloading rack 401 drives the vacuum suction cup 402 to move to the top of the lower mold 2. The electric cylinder 403 can drive the vacuum suction cup 402 to move up and down. The vacuum suction cup 402 sucks the formed FRP septic tank and can be removed from the lower mold 2 by the rising of the unloading rack 401. The vacuum suction cup 402 is driven away from the lower mold 2 by the unloading rack 401 to complete the unloading. It should be added that the vacuum suction cup 402 adopts a corrugated suction cup with extremely soft and smooth sealing lips, which can achieve optimal adaptability and can carry workpieces with uneven cloth surfaces and curved workpieces. At the same time, the size of the vacuum suction cup 402 is much smaller than the size of the fiberglass septic tank. The contact surface between the vacuum suction cup 402 and the fiberglass septic tank can be approximately flat, which can ensure sufficient suction to the fiberglass septic tank. If you want to further increase the suction force of the vacuum suction cup 402, you can only use the two suction cups on the same side of the vacuum suction cup 402 to adsorb the top of the fiberglass septic tank. The two suction cups are in the same plane and on the same straight line, which ensures the adsorption effect. The vacuum suction cup 402 is also equipped with a clamping plate 801 to clamp the fiberglass septic tank, which further ensures the stability of the fiberglass septic tank.

[0067] like Figures 1 to 3 as well as Fig.11As shown, in order to realize the alternating operation of the loading mechanism and the unloading mechanism, a driving mechanism is also included, and the driving mechanism is used to drive the loading mechanism and the unloading mechanism to move. The driving mechanism includes a moving frame 501, a driving frame 502, a driving gear 503, a driven rack 1 504 and a driven rack 2 505. A roller 506 is arranged at the bottom of the moving frame 501, and the roller 506 has a self-locking mechanism to fix the position of the moving frame 501. The driving frame 502 can be lifted and arranged on the moving frame 501, and an electric cylinder 3 507 is arranged on the moving frame 501. The driving frame 502 is arranged at the output end of the electric cylinder 3 507. The driving gear 503 can be rotatably arranged on the driving frame 502, and a motor 2 508 is arranged on the driving frame 502. The driving gear 503 is arranged on the electric cylinder 3 507. At the output end of the second machine 508, the driven rack 1 504 is arranged on the loading frame 301, and the driven rack 2 505 is arranged on the unloading frame 401. The driven rack 1 504 and the driven rack 2 505 are centrally symmetrical with respect to the driving gear 503, and the driven rack 1 504 and the driven rack 2 505 are both meshed with the driving gear 503. The driven rack 1 504 and the driven rack 2 505 are both slidably matched with the driving frame 502. The driven rack 1 504 and the driven rack 2 505 are both connected with a slider. The driving frame 502 is provided with a slide groove matching the slider. The movement of the movable frame 501 can be realized by the roller 506. The driving frame 502 can be driven to rise and fall by the electric cylinder 3 507, thereby driving the unloading frame 401 to rise and fall, so that the vacuum suction The plate 402 drives the formed FRP septic tank to rise and separate from the lower mold 2. The motor 2 508 can drive the driving gear 503 to rotate, thereby driving the driven rack 1 504 and the driven rack 2 505 to move relative to each other. When the driven rack 2 505 drives the unloading rack 401 and the vacuum suction cup 402 to move between the upper mold 1 and the lower mold 2 for unloading, the driven rack 1 504 drives the loading frame 301 to a position away from the upper mold 1 and the lower mold 2. At this time, the blanking plate 302 is in a horizontal state, and the raw material sheet can be placed on the blanking plate 302. After the vacuum suction cup 402 sucks the FRP septic tank, the electric cylinder 3 507 drives the unloading rack 401 and the loading frame 301 to rise, and the driving gear 503 rotates, so that the driven rack 2 505 drives the vacuum suction cup 402 to a position away from the upper mold 1 and the lower mold 2. The driven rack 1 504 drives the loading frame 301 to move between the upper mold 1 and the lower mold 2, and the electric cylinder 3 507 drives the driving frame 502 to descend, and the motor 1 303 drives the blanking plate 302 to rotate downward, and the raw material sheet falls onto the lower mold 2 to realize the switching of loading and unloading. When the middle position of the driven rack 1 504 and the driven rack 2 505 is engaged with the driving rack, the upper and lower positions of the loading frame 301 and the unloading frame 401 correspond to each other, and are far away from the upper mold 1 and the lower mold 2. At this time, the position of the moving frame 501 can be fixed to realize loading and unloading, and the vacuum suction cup 402 is released from the glass fiber reinforced plastic septic tank, so that the glass fiber reinforced plastic septic tank can be collected and subsequently processed, or when the vacuum suction cup 402 is fixed to the glass fiber reinforced plastic septic tank,The FRP septic tank can also be moved by the movement of the mobile frame 501 to move it to the storage position, and the driving frame 502 can be driven to rise and fall by the electric cylinder 3 507, thereby driving the FRP septic tank to rise and fall, and it can be placed on top of other FRP septic tanks for stacking.

[0068] like Figures 6 to 10 As shown, the fiberglass septic tank is detached from the upper mold 1 and the lower mold 2 after auxiliary molding, and also includes a demolding mechanism, which includes an air blowing pipe 601, a demolding pipe 602 and a push plate 603. Two air blowing pipes 601 are provided, and the two air blowing pipes 601 are respectively arranged inside the upper mold 1 and the lower mold 2. The heat conduction plate 202 isolates a plurality of demolding cavities inside the heat conduction bin 201, and the demolding cavities and the cold water cavities 204 are alternately arranged. The demolding cavities are connected to the air blowing pipe 601, and the demolding The tube 602 is provided with multiple pieces, the demoulding tube 602 is connected with the demoulding cavity, the demoulding tube 602 is stepped, the side with smaller diameter of the demoulding tube 602 is connected with the demoulding cavity, the end with larger diameter of the demoulding tube 602 passes through the upper mold 1 or the lower mold 2, the push plate 603 is arranged inside the demoulding tube 602 through the return spring 604 and the telescopic rod, the side with smaller diameter of the demoulding tube 602 is provided with a fixed plate 605, the return spring 604 and the telescopic rod are arranged on the fixed plate 605 on the side away from the push plate 603, the push plate 603 and the side with larger diameter of the demoulding tube 602 are sealed and slidably matched, the push plate 603 and the demoulding tube 602 are adapted to the cavity surface of the upper mold 1 or the lower mold 2, the air blowing tube 601 is connected with the external air supply device, the external air supply device supplies air to the inside of the demoulding cavity through the air blowing tube 601, the pressure inside the demoulding cavity is increased, and the push plate 603 is pushed out from the inside of the demoulding tube 602, and the push plate 603 pushes the formed glass The steel septic tank is pushed away from the upper mold 1 and the lower mold 2 to realize the demolding of the glass fiber reinforced plastic septic tank, which is convenient for the subsequent vacuum suction cup 402 and the clamping plate 801 to unload the glass fiber reinforced plastic septic tank. After the external air supply equipment stops supplying air to the interior of the demolding cavity, the push plate 603 is moved to the interior of the demolding tube 602 under the action of the reset spring 604 to form the cavity of the upper mold 1 and the lower mold 2, and cooperate with the upper mold 1 and the lower mold 2 to perform molding, while preventing the raw materials from entering the interior of the demolding tube 602.

[0069] like Figures 6 to 10As shown, in order to reduce the heat exchange between the cooling mechanism and the heater 3, a drainage component is also included, and the drainage component is used to drain the water in the cold water chamber 204. The drainage component includes a drainage pipe 701 and a one-way valve 702. Two drainage pipes 701 are provided.

[0071] The working principle or use process of this environmentally friendly FRP septic tank forming and processing equipment is:

[0072] Initially, the blanking plate 302 is in a horizontal state. First, the raw material sheet is placed on the blanking plate 302. The motor 2 508 drives the driving gear 503 to rotate, so that the driven rack 1 504 drives the loading frame 301 to a position close to the upper mold 1 and the lower mold 2. The hydraulic cylinder 104 drives the upper mold 1 to a higher position, and pushes the moving frame 501 to move the loading frame 301 to between the upper mold 1 and the lower mold 2. The motor 1 303 drives the blanking plate 302 to rotate downward, and the raw material sheet falls on the surface of the lower mold 2. Then, the movable frame 501 is pushed to move the loading frame 301 out from between the upper die 1 and the lower die 2, and the position of the movable frame 501 is fixed. The motor 2 508 drives the driving gear 503 to rotate, so that the middle position of the driven rack 1 504 and the driven rack 2 505 is meshed with the driving gear 503, and the loading frame 301 is moved out from between the upper die 1 and the lower die 2. The motor 1 303 drives the blanking plate 302 to rotate to a horizontal state again, and the subsequent raw material sheets can be placed on the blanking plate 302;

[0073] The hydraulic cylinder 104 drives the upper mold 1 to descend and close to the lower mold 2. Before loading, the heater 3 is turned on to preheat the upper mold 1 and the lower mold 2. The electric cylinder 104 drives the heater 3 to approach the heat transfer bin 201. The heat transfer bin 201 and the heat transfer plate 202 transfer the heat of the heater 3 to the cavity of the upper mold 1 and the lower mold 2, and the raw material sheet between the upper mold 1 and the lower mold 2 is heated and softened. The softened raw material sheet flows to fill the cavity. When the curing temperature is reached, the sheet is cured and formed between the upper mold 1 and the lower mold 2, and then the heater 3 is turned off. At the same time, the electric cylinder 104 drives the heater 3 away from the heat transfer bin 201. The hot chamber 201, the three-way valve 5 controls the air blowing pipe 601 and the air inlet pipe 6 to be connected, and the external cooling device delivers cold water to the inside of the cold water chamber 204 through the cold water pipe 203, and the cold water cools the heat conducting plate 202 and the heat conducting chamber 201, thereby cooling the glass fiber reinforced plastic septic tank between the upper mold 1 and the lower mold 2, and the external air supply device delivers air to the air blowing pipe 601 and the inside of the demoulding cavity, and the pressure in the demoulding cavity increases to drive the push plate 603 to push the glass fiber reinforced plastic septic tank away from the upper mold 1 and the lower mold 2, and the hydraulic cylinder 104 drives the upper mold 1 to rise, and the glass fiber reinforced plastic septic tank remains on the lower mold 2;

[0074] The motor 2 508 drives the driving gear 503 to rotate, drives the driven rack 2 505 to drive the unloading rack 401 to move to a position close to the lower mold 2, and the electric cylinder 2 403 drives the vacuum suction cup 402 to descend to attract the FRP septic tank. The motor 3 802 drives the bidirectional screw 803 to rotate, drives the clamping plate 801 to clamp the FRP septic tank, and then the electric cylinder 3 507 drives the driving rack 502 and the unloading rack 401 to rise, drives the FRP septic tank to rise and separate from the lower mold 2, and the motor 2 508 drives the driving gear 503 to rotate, so that the driven rack 2 505 drives the vacuum suction cup 402 to descend to attract the FRP septic tank. The movable unloading rack 401 moves away from the lower mold 2, and at the same time, the driven rack 1 504 drives the loading frame 301 to move between the upper mold 1 and the lower mold 2, and the vacuum suction cup 402 releases the attraction on the FRP septic tank. The motor 3 802 reverses and drives the two clamping plates 801 to move away from each other, releasing the clamping of the FRP septic tank, so that the FRP septic tank can be collected and subsequently processed. After loading and unloading, the motor 2 508 drives the driving gear 503 to rotate, so that the loading frame 301 and the unloading rack 401 are moved to a position outside the upper mold 1 and the lower mold 2, and the raw material sheet can be heated and formed.
