Description

Technical Field

[0001] This utility model relates to the field of cooling technology for vacuum forming machines, and in particular to a deformation-resistant and high-efficiency cooling vacuum forming device. Background Technology

[0002] The significance of cooling products in blow molding machines lies in ensuring the product's geometry and internal structure, improving product quality and production efficiency. During the production process, the cooling step ensures the internal structure and geometry of the product. The cooling process is crucial for blow-molded products because it prevents deformation under gravity, which would affect the product's structure.

[0003] According to the description of a cooling device for a vacuum forming machine disclosed on the patent website (authorization announcement number: CN219543997U), "the vacuum forming mold has mounting grooves at its upper and lower ends, a small air pump is installed in the mounting groove, the air inlet of the small air pump is connected to an air inlet pipe, and a connecting air pipe is installed on the air inlet pipe, a corrugated pipe is connected to the output port of the small air pump, a guide pipe is installed on the corrugated pipe, and a cooling pipe is connected to the guide pipe, a centralized air inlet is installed on the side of the cooling pipe, and electric telescopic rods are installed at both ends of the centralized air inlet, and slide rails are connected to the electric telescopic rods."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model has a low cooling efficiency because the corrugated pipe is equipped with a guide tube, the guide tube is connected to a cooling pipe, the cooling pipe has a central air inlet on its side, and the two ends of the central air inlet are equipped with electric telescopic rods, which are connected to slide rails. At the same time, the cooling gas may contain impurities. Therefore, it is necessary to improve the device to provide a deformation-resistant and efficient cooling thermoforming device to solve the above problems. Utility Model Content

[0006] To overcome the problems of low cold cutting efficiency in existing technologies and the potential presence of impurities in the cooling gas.

[0007] The technical solution of this utility model is as follows: A deformation-resistant, high-efficiency cooling vacuum forming device includes a vacuum forming machine, a feeding rack located in front of the vacuum forming machine and a discharging rack located behind the vacuum forming machine. The vacuum forming machine includes a frame, on which a platform is provided. A vacuum forming mold is detachably mounted on the platform by bolts. An outer cover covers the vacuum forming machine. A high-power fan filter unit is provided above the outer cover. The high-power fan filter unit includes two fan modules. Heat insulation plates are spaced apart below the high-power fan filter unit. The heat insulation plates are made of heat insulation material. An air outlet device one is provided on the side of the heat insulation plate corresponding to the vacuum forming mold near the feeding rack, and an air outlet device two is provided on the side of the heat insulation plate corresponding to the vacuum forming mold near the discharging rack.

[0008] Preferably, the raw material for blow molding is fed into the vacuum forming machine through the discharge rack. After the material is blow molded, it is removed from the feed rack. The detachable vacuum forming mold facilitates easy replacement for different products. The two sets of fan modules can increase the cooling airflow of the high-power fan filter unit. The high-power fan filter unit has a filtration function, which can effectively prevent the vacuum-formed product from being contaminated by dust. The air blown onto the vacuum-formed product by the air outlet device one and the air outlet device two together helps to prevent deformation and achieve efficient cooling.

[0009] Preferably, the high-power fan filter unit and the heat insulation plate are separated by a U-shaped aluminum alloy frame on the outer cover. The U-shaped aluminum alloy frame has an opening on its side, and a one-way vent valve is installed in the opening. The use of the U-shaped aluminum alloy frame can make the outer cover lighter. At the same time, thanks to the U-shaped design, it can support the high-power fan filter unit. When the air outlet device one and the air outlet device two are closed, the airflow generated by the high-power fan filter unit can be discharged from the one-way vent valve at the opening. The reason for using the one-way vent valve is to prevent airflow backflow.

[0010] Preferably, the first air outlet device includes an air outlet nozzle, and the second air outlet device includes an air outlet nozzle. The air outlet nozzle 1 and the air outlet nozzle 2 are respectively directed toward the central area of ​​the blister mold. By blowing air toward the central area of ​​the blister mold, it helps the product on the blister mold to cool down quickly and prevents the product from deforming due to external forces while it has not cooled down for a long time.

[0011] Preferably, in the first air outlet device, the side of the air outlet nozzle away from the air outlet is the first cooling plate; in the second air outlet device, the side of the air outlet nozzle away from the air outlet is the second cooling plate. Liquid nitrogen flows within the first and second cooling plates. To achieve better cooling, the airflow generated by the high-power fan filter unit passes through the first and second cooling plates and is blown out, thus cooling the airflow and achieving efficient cooling of the product on the thermoforming mold. The reason why liquid nitrogen can flow within the first and second cooling plates is that each of the first and second cooling plates has a cavity, and the outer surfaces of the first and second cooling plates have inlet and outlet pipes for liquid nitrogen connecting the cavities, thereby enabling the flow of liquid nitrogen.

[0012] Preferably, the first air outlet is provided with a first air regulating plate on the side near the first air outlet; the second air outlet is provided with a second air regulating plate on the side near the second air outlet. The first air regulating plate and the second air regulating plate can adjust the air direction. The first air regulating plate and the second air regulating plate are driven by motors respectively. The direction of the airflow can be adjusted by the first air regulating plate and the second air regulating plate driven by the motors.

[0013] Preferably, the width of the first and second air outlets is a, and the width of the vacuum forming mold is b, where a=b. After the first and second air regulating plates are rotated at a certain angle, they can completely block the first and second air outlets. In order to prevent the product from being deformed by the cooling airflow during blow molding, the first and second air regulating plates can close the first and second air outlets during the blow molding period.

[0014] As a preferred option, air outlet 1, air outlet 2, air regulating plate 1, air regulating plate 2, and heat insulation plate are made of asbestos. In order to isolate the heat of the vacuum forming mold and maintain the low temperature of the airflow inside air outlet 1 and air outlet 2, air outlet 1, air outlet 2, air outlet 1, and heat insulation plate are made of asbestos material.

[0015] The beneficial effects of this utility model are:

[0016] 1. The feeding rack feeds the raw material for blow molding into the vacuum forming machine. After the material is blow molded, it will be removed from the feeding rack. The detachable vacuum forming mold helps to easily change it for different products. The two sets of fan modules can increase the cooling airflow of the high-power fan filter unit. The high-power fan filter unit has a filtration function, which can effectively prevent the vacuum-formed products from being contaminated by dust. The air blown onto the vacuum-formed products by the air outlet device one and air outlet device two together helps to prevent deformation and provides efficient cooling. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-6 This utility model provides an embodiment: a deformation-resistant, high-efficiency cooling thermoforming device, including a thermoforming machine 1, a feeding rack 2 located in front of the thermoforming machine 1 and a discharging rack 3 located behind the thermoforming machine 1. The thermoforming machine 1 includes a frame 19, on which a platform 12 is provided. A thermoforming mold 13 is detachably mounted on the platform 12 by bolts. An outer cover 14 covers the thermoforming machine 1. A high-power fan filter unit 15 is provided above the outer cover 14. The high-power fan filter unit 15 includes two fan modules 151. Heat insulation plates 16 are spaced apart below the high-power fan filter unit 15. The heat insulation plates 16 are made of heat insulation material. An air outlet device 17 is provided on the side of the heat insulation plate 16 corresponding to the thermoforming mold 13 near the feeding rack 2, and an air outlet device 18 is provided on the side of the heat insulation plate 16 corresponding to the thermoforming mold 13 near the discharging rack 3. The material for blow molding is fed into the vacuum forming machine 1 through the discharge rack 3. After the material is blow molded, it will be removed from the feed rack 2. The detachable vacuum forming mold 13 helps to easily replace it for different products. The two sets of fan modules 151 can increase the cooling airflow of the high-power fan filter unit 15. The high-power fan filter unit 15 has a filtration function, which can effectively prevent the vacuum-formed product from being contaminated by dust. The air blown onto the vacuum-formed product by the air outlet device 17 and the air outlet device 2 18 together helps to prevent deformation and provides efficient cooling.

[0026] Please see Figures 1-5In this embodiment, the high-power fan filter unit 15 and the heat insulation plate 16 are separated by a U-shaped aluminum alloy frame 11 on the outer cover 14. The U-shaped aluminum alloy frame 11 has an opening 111 on its side, and a one-way ventilation valve 112 is installed in the opening 111. The use of the U-shaped aluminum alloy frame 11 makes the outer cover 14 lighter, and the U-shaped design can support the high-power fan filter unit 15. When the air outlet device 17 and the air outlet device 2 18 are closed, the airflow generated by the high-power fan filter unit 15 can be discharged from the one-way ventilation valve 112 at the opening 111. The reason for using the one-way ventilation valve 112 is to prevent airflow backflow. The first air outlet device 17 includes an air outlet 171, and the second air outlet device 18 includes an air outlet 181. The air outlets 1711 and 1811 of the first and second air outlets 181 respectively face the central area of ​​the vacuum forming mold 13. By blowing air towards the central area of ​​the vacuum forming mold 13, it helps to quickly cool the product on the vacuum forming mold 13 and prevents the product from deforming due to prolonged lack of cooling and external forces. In the first air outlet device 17, the side of the air outlet 171 away from the air outlet 1711 is a cooling plate 1712; in the second air outlet device 18, the side of the air outlet 181 away from the air outlet 1811 is a cooling plate 1812. Liquid nitrogen flows within the cooling plate 1712 and the cooling plate 1812. To achieve better cooling, the airflow generated by the high-power fan filter unit 15 passes through cooling plate 1712 and cooling plate 1812, serving to cool the airflow and thus achieving efficient cooling of the product on the thermoforming mold 13. The reason liquid nitrogen can flow within cooling plate 1712 and cooling plate 1812 is that each cooling plate 1712 and cooling plate 1812 has a cavity, and the outer surfaces of cooling plate 1712 and cooling plate 1812 have inlet and outlet pipes connecting the cavities, thereby enabling the flow of liquid nitrogen. A regulating plate 17111 is provided on the side of the air outlet 1711 near the air outlet 1711; a regulating plate 18111 is provided on the side of the air outlet 1811 near the air outlet 1811. The regulating plates 17111 and 18111 can adjust the airflow direction, and are driven by motors. The direction of the airflow can be adjusted by the motor-driven regulating plates 17111 and 18111.

[0027] Please see Figures 3-6In this embodiment, the width of air outlet 1711 and air outlet 1811 is 'a', and the width of the vacuum forming mold 13 is 'b', where a = b. The air regulating plates 17111 and 18111 can completely block air outlet 1711 and 18111 after rotating a certain angle. To prevent deformation of the product due to interference from the cooling airflow during blow molding, the air regulating plates 17111 and 18111 can close air outlet 1711 and 18111 during the blow molding process. Air outlet 171, air outlet 181, air regulating plates 17111 and 18111, and the heat insulation plate 16 are made of asbestos. In order to insulate the heat of the thermoforming mold 13 and maintain the low temperature of the airflow inside the air outlet 17 and the air outlet 2 18, the air outlet 171, the air outlet 2 181, the air outlet 1711, the air outlet 2 1811, and the heat insulation plate 16 are made of asbestos material.

[0028] During operation, the material from the discharge rack 3 enters the vacuum forming machine 1 through the roller frame. The vacuum forming machine 1 has four sets of rollers at its inlet to pull the product, and simultaneously, these rollers push the product to the pressure device above the vacuum forming mold 13. Rotary cylinders on both sides of the pressure device press the product onto it. A synchronous lifter at the bottom of the pressure device lowers the product. A vacuum suction device near the vacuum forming mold 13 absorbs air for vacuum forming. After vacuum forming, the rotary cylinders release the pressed product. Simultaneously, the air regulating plates 17111 and 18111 are opened by the motor, and the airflow generated by the high-power fan filter unit 15 enters the cavity formed by the high-power fan filter unit 15, the U-shaped aluminum alloy frame 11, and the heat insulation plate 16. The heat insulation plate 16 has two holes corresponding to the air outlet devices 17 and 18. The airflow enters the air outlet devices 17 and 18 through these holes. The airflow passes through the air outlet devices... When the airflow passes through cooling plates 1712 and 1812, the airflow is cooled by flowing liquid nitrogen inside the cooling plates 1712 and 1812. This lowers the airflow temperature of the high-power fan filter unit 15. The airflow is ejected from the air outlets 1711 and 1811, respectively. At the same time, the air regulating plates 17111 and 18111 can adjust the airflow direction. After the product cools down, the synchronous lifter drives the pressing device to rise, which in turn lifts the blow-molded product to the height of the front roller group. The roller group moves backward to receive the product and then moves forward to send the product to the discharge rack 3. It is worth noting that the high-power fan filter unit 15 is always operating during the blow molding process, but the air outlets 1711 and 1811 are closed by the air regulating plates 17111 and 18111. The airflow generated during this period is discharged from the one-way ventilation valve 112.

[0029] Through the above steps, the discharge rack 3 conveys the raw material for blow molding into the vacuum forming machine 1. After the raw material is blow molded, it will be removed from the feed rack 2. The detachable vacuum forming mold 13 helps to facilitate the replacement for different products. The two sets of fan modules 151 can increase the cooling airflow of the high-power fan filter unit 15. The high-power fan filter unit 15 has a filtering function, which can effectively prevent the vacuum-formed product from being contaminated by dust. The air blown by the first air outlet 17 and the second air outlet 18 together towards the vacuum-formed product helps to prevent deformation and achieve efficient cooling, so as to solve the problems of low cold cutting efficiency in the existing technology and the possibility of impurities in the cooling gas.
