Description

Technical Field

[0001] This utility model relates to the field of blow molding equipment technology, specifically an automatic high-speed vacuum thermoforming machine. Background Technology

[0002] Vacuum forming packaging products are a type of packaging products made from thermoplastic sheets (such as PVC, PET, PP, etc.) as the base material, which are softened by heating and then adsorbed onto the surface of a mold to form a shape. They are widely used in the fields of electronics, food, and medicine. Vacuum forming machines are used to process thermoplastic sheets, and various packaging products of different shapes can be made by changing different molds.

[0003] In the prior art, patent publication number CN210651836U discloses a vacuum forming machine, including a frame for enclosing other components of the vacuum forming machine; a feeding mechanism disposed on the outer side of the frame for conveying plastic sheets; and a vacuum forming mechanism disposed on the frame for vacuum forming the plastic sheets. The vacuum forming mechanism includes an upper mold, a lower mold, an upper vacuum forming platform, a lower vacuum forming platform, and a driving device. The upper vacuum forming platform is movably mounted on the upper part of the frame for mounting the upper mold. The lower vacuum forming platform is movably mounted on the lower part of the frame and is disposed opposite to the upper vacuum forming platform for mounting the lower mold. The driving device is mounted on the frame for driving the upper and lower vacuum forming platforms to move closer or further apart so that the upper and lower molds contact or release contact with the plastic sheets.

[0004] Existing vacuum forming machines of this type have the following disadvantages: after heating the plastic sheet, the oven needs to be pushed out first, and then the upper and lower drive cylinders are started to drive the upper and lower vacuum forming platforms to fit the plastic sheet for vacuum forming. The operation steps are numerous, which affects the vacuum forming efficiency of the plastic sheet. Therefore, we propose an automatic high-speed vacuum forming machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an automatic high-speed vacuum forming machine.

A connecting rod is rotatably connected between slider one and slider two on the front side. Through the linkage mechanism, when the heating chamber moves, the mold mounting seat moves through the transmission of the connecting rod, so that the movement of the heating chamber and the contact between the mold and the blow molding material are carried out simultaneously, which simplifies the operation steps and improves the efficiency of vacuum forming of vacuum forming materials.

[0008] Furthermore, a microcontroller is fixedly connected to the front surface of the frame.

The input end of the electric push rod is electrically connected to the output end of the microcontroller to provide driving force.

[0010] Furthermore, an electric heating wire is fixedly connected to the upper surface of the heating chamber, and temperature sensors are uniformly distributed and fixedly connected to the upper surface of the heating chamber.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This embodiment provides a technical solution: an automatic high-speed vacuum forming machine, including a frame 1, a support frame 2 fixedly connected to the upper surface of the frame 1, an adjustable mold 10 provided on the left side inside the frame 1, a vacuum pump 14 fixedly connected to the right side inside the frame 1, a microcontroller 4 fixedly connected to the front surface of the frame 1, the input end of the microcontroller 4 electrically connected to an external power source, the input end of the vacuum pump 14 electrically connected to the output end of the microcontroller 4, an electric push rod 15 fixedly connected to the rear side inside the support frame 2, a limit block 8 fixedly connected to the lower side of the telescopic end of the electric push rod 15, and a blow molding material (such as polyethylene) is passed between the upper surface of the frame 1 and the lower surface of the limit block 8. The left end of the plastic material is connected to the external traction device. The microcontroller 4 is operated to start the electric push rod 15. The telescopic end of the electric push rod 15 extends and pushes the limit block 8 downward, so that the lower surface of the limit block 8 squeezes the blow molding material, thereby fixing the blow molding material. The input end of the electric push rod 15 is electrically connected to the output end of the microcontroller 4. The front and rear sides of the support frame 2 are fixedly connected to the air blowing pipes 13. The lower end of the air blowing pipes 13 is fixedly connected to the nozzles. The upper end of the air blowing pipes 13 is connected to the external air supply pipe. Low temperature gas is sprayed from the nozzles through the air blowing pipes 13 to the surface of the blow molding material, thereby cooling and shaping the blow molding material. The system also includes a linkage mechanism 7.

[0022] The linkage mechanism includes a track 71, a slider 72, a connecting rod 73, a second slider 74, and a second track 75. Track 71 is fixedly connected to the front and rear sides of the support frame 2. Sliding sliders 72 are slidably connected inside each track 71. A heating chamber 3 is fixedly connected between two sliders 72. An electric push rod 6 is fixedly connected to the right side of the support frame 2. The left end of the extension / retraction end of the electric push rod 6 is fixedly connected to the right surface of the heating chamber 3. The input end of the electric push rod 6 is electrically connected to the output end of the microcontroller 4. A heating wire 11 is fixedly connected to the upper surface of the heating chamber 3. Temperature sensors 12 are uniformly distributed and fixedly connected to the upper surface of the heating chamber 3. The detection ends of the temperature sensors 12 all penetrate into the interior of the heating chamber 3. The temperature sensors 12 are connected to the microcontroller 4. Microcontroller 4 is bidirectionally electrically connected, and the input end of heating wire 11 is electrically connected to the output end of microcontroller 4. Operating microcontroller 4 activates electric push rod 6, extending its telescopic end to move heating chamber 3 to the left, directly above limit block 8. Operating microcontroller 4 then activates heating wire 11, which generates heat to heat the blow-molded material below. (The outer surface of heating chamber 3 is made of foamed ceramic material, which isolates the heat generated inside, reducing heat loss and preventing heat leakage or heat transfer that could damage other electrical components.) Temperature sensor 12 monitors the temperature inside heating chamber 3 and converts the monitored temperature data into an electrical signal, which is then transmitted to microcontroller 4 for temperature monitoring and control. After heating for a period of time, the blow molding material softens due to heat. Then, the heating wire 11 is turned off. Tracks 75 are fixedly connected to both the front and rear sides of the frame 1. Sliding sliders 74 are slidably connected inside each track 75. A mold fixing seat 5 is fixedly connected between the two sliders 74. The right surface of the mold fixing seat 5 is connected to the air inlet of the vacuum pump 14 via a flexible air supply hose. The mold 10 is fixedly connected to the upper surface of the mold fixing seat 5. The upper surface of the mold fixing seat 5 has evenly distributed through holes 9. A connecting rod 73 rotatably connects the front slider 72 and the front slider 74. At this time, the microcontroller 4 is operated to retract the telescopic end of the electric push rod 6, causing the heating chamber 3 to move to the right (slider 72 and track 71 support the heating chamber, making...). The telescopic end of electric push rod 6 is only subjected to axial force, thus protecting electric push rod 6 and preventing it from being easily damaged. This causes slider 72 to slide inside track 71, moving connecting rod 73 and causing slider 74 to slide upwards inside track 75. This moves mold mounting base 5 upwards, causing mold 10 to move upwards until the upper surface of mold mounting base 5 is in close contact with the inner upper surface of frame 1. At this point, mold 10 passes through the clearance groove on the left side of the upper surface of frame 1 and contacts the softened blow molding material. The microcontroller 4 is then activated, starting vacuum pump 14. Vacuum pump 14 extracts the gas inside mold mounting base 5 and the gas between the blow molding material and the upper surface of mold mounting base 5, thus causing the blow molding material to adhere tightly to the outer surface of mold 10.Operate the microcontroller 4 to retract the telescopic end of the electric push rod 15, causing the limit block 8 to move upward. Operate the microcontroller 4 to extend the telescopic end of the electric push rod 6, causing the heating chamber 3 to move to the left, causing the slider 72 to slide inside the track 71, causing the connecting rod 73 to move, causing the slider 74 to slide downward inside the track 75, causing the mold mounting base 5 to move downward, causing the mold 10 to move downward, separating the mold 10 from the blow molding material. At this time, operate the external traction device to pull the molded blow molding material to the left, causing the molded blow molding material to leave from the upper side of the clearance groove. Then turn off the external traction device, and then operate the microcontroller 4 to turn on the heating wire 11 again. This process is repeated to realize the blow molding operation of the blow molding material.

[0023] The working principle of the automatic high-speed vacuum forming machine provided by this utility model is as follows: When using this automatic high-speed vacuum forming machine for blow molding, the blow molding material (such as polyethylene) is passed between the upper surface of the frame 1 and the lower surface of the limiting block 8. The left end of the blow molding material is connected to the external traction device. The microcontroller 4 is operated to start the electric push rod 15. The telescopic end of the electric push rod 15 extends, pushing the limiting block 8 downward, so that the lower surface of the limiting block 8 squeezes the blow molding material, thereby fixing the blow molding material. Then, the microcontroller 4 is operated to start the electric push rod 6. The telescopic end of the electric push rod 6 extends, so that the heating chamber 3 moves to the left and is directly above the limiting block 8. The microcontroller 4 is operated to start the heating wire 11. The heat generated heats the blow molding material below (the outer surface of the heating chamber 3 is made of foamed ceramic material, which blocks the heat generated inside the heating chamber 3, reduces heat loss, and prevents heat leakage or heat transfer from damaging other electrical appliances). The detection end of the temperature sensor 12 monitors the temperature inside the heating chamber 3 and converts the monitored temperature data into an electrical signal, which is then transmitted to the microcontroller 4 to monitor and regulate the temperature inside the heating chamber 3. After heating for a period of time, the blow molding material softens due to the heat, and then the heating wire 11 is turned off. At this time, the microcontroller 4 is operated to retract the telescopic end of the electric push rod 6, causing the heating chamber 3 to move to the right, which in turn causes the slider 72 to slide inside the track 71, moving the connecting rod 73 and causing the slider to move. The second 74 slides upward inside the second 75, causing the mold mounting base 5 to move upward, which in turn moves the mold 10 upward until the upper surface of the mold mounting base 5 is in close contact with the inner upper surface of the frame 1. At this time, the mold 10 passes through the clearance groove on the left side of the upper surface of the frame 1 and comes into contact with the softened blow molding material. At this time, the microcontroller 4 is operated to start the vacuum pump 14. The vacuum pump 14 runs and extracts the gas inside the mold mounting base 5 and the gas between the blow molding material and the upper surface of the mold mounting base 5, so that the blow molding material is in close contact with the outer surface of the mold 10. The upper end of the blowing pipe 13 is connected to the external gas supply pipe. Low temperature gas is sprayed from the nozzle through the blowing pipe 13 onto the surface of the blow molding material, thereby cooling and shaping the blow molding material. After the blow molding material cools down... After shaping, operate the microcontroller 4 to retract the telescopic end of the electric push rod 15, causing the limit block 8 to move upward. Then, operate the microcontroller 4 to extend the telescopic end of the electric push rod 6, causing the heating chamber 3 to move to the left. This causes the slider 72 to slide inside the track 71, moving the connecting rod 73 and causing the slider 74 to slide downward inside the track 75. This causes the mold mounting base 5 to move downward, moving the mold 10 downward and separating the mold 10 from the blow molding material. At this time, operate the external traction device to pull the molded blow molding material to the left, causing it to leave the upper side of the clearance groove. Then, turn off the external traction device. After that, operate the microcontroller 4 to turn on the heating wire 11 again. Repeat this process to achieve the blow molding operation of the blow molding material.
