[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] See also Figure 1The present embodiment provides a vacuum shaping machine for producing polycarbonate, including a chassis 1, a polycarbonate tube passes through the inlet of the chassis 1, passes through the outlet of the chassis 1, and completes cooling and shaping in the chassis 1. The chassis 1 is provided with an inlet and an outlet on both sides, and the inlet and the outlet are on the same horizontal line. The chassis 1 is provided with a clamping assembly 21 at the inlet, and the clamping assembly 21 is used to clamp the polycarbonate tube embryo and enter the chassis 1. A shaping cavity 22 is provided on one side of the clamping assembly 21 and inside the chassis 1. The polycarbonate tube embryo is transported to the shaping cavity 22 through the clamping assembly 21. The shaping cavity 22 is connected to a vacuum pump through a connecting pipe. The polycarbonate tube embryo with an irregular shape is adsorbed to the outer surface through vacuum extrusion and tightly fits with the inner wall of the shaping cavity 22 to form a regular polycarbonate tube;

[0020] Inside the chassis 1, a support assembly is installed on one side of the molding cavity 22. The support assembly is installed on the inner wall of the bottom surface of the chassis 1 and is used to support the polycarbonate tube that has not been completely cooled. A fan 41 and a drive motor 42 are arranged outside the chassis 1. The fan 41 conveys cold air to the inside of the chassis 1 through the blast channel. A plurality of air outlets are arranged on the side wall of the chassis 1 connected to the outside. The air outlets cooperate with the blower 41 to realize air circulation inside the chassis 1, thereby accelerating the cooling and molding speed of the polycarbonate tube. The output end of the drive motor 42 is connected to the fan 41 to drive the fan 41 to rotate. The drive motor 42 can adjust the power of the fan 41 according to the feeding speed of the polycarbonate tube embryo on the clamping assembly 21, so as to meet the cooling conditions and avoid the waste of resources. After the polycarbonate tube embryo that has been adsorbed and molded leaves the molding cavity 22, the support assembly supports and buffers it, and the cold air from the air outlet of the fan 41 on the support assembly is quickly cooled, hardened and molded, and passes through the inside of the chassis 1 through the outlet to complete the molding process.

[0021] Furthermore, in order to improve the stability of the support assembly and increase the residence time of the incompletely formed polycarbonate tube in the chassis 1 to achieve the cooling and forming effect, the support assembly includes a bracket 32, and the bracket 32 ​​includes two parallel mounting grooves. A plurality of rollers 33 are installed between the two mounting grooves. The number of rollers 33 is designed to match the length of the polycarbonate tube. The surface of the roller 33 is smooth, and the surface of the roller 33 abuts against the outer surface of the polycarbonate tube. When the polycarbonate tube at the inlet end is continuously fed, the polycarbonate tube coming out of the forming cavity 22 is positioned and moved to the outlet direction by rolling the surface of the polycarbonate tube and the surface of the roller 33.

[0022] Furthermore, in order to achieve the abutment between the surface of the roller 33 and the surface of the polycarbonate tube, the support assembly also includes an electric push rod 31, the fixed end of the electric push rod 31 is fixedly connected to the inner bottom surface of the chassis 1, and the push rod of the electric push rod 31 is connected to the bracket 32 ​​through a support block. The electric push rod 31 is used to push the roller 33 on the support assembly to abut against the outer surface of the polycarbonate tube to ensure the support of the polycarbonate tube by the support assembly; according to the principle of mechanics, the electric push rod 31 is installed at the central axis position of the bracket 32 ​​assembly, and a support block is added between the electric push rod 31 and the support assembly. The support block is used to increase the support area of ​​the electric push rod 31 on the bracket 32 ​​and balance the support force of the electric push rod 31 on the bracket 32. In order to meet the abutment requirements, the highest point on the upper surface of the roller 33 and the lowest height difference between the molding cavity 22 is the thickness of the molding cavity 22. The polycarbonate tube coming out of the molding cavity 22 will have a thrust due to the non-stop loading, so that it can move on the support assembly until the outlet to complete cooling and shaping.

[0023] Furthermore, in order to meet the production of polycarbonate tubes of different sizes, when the molding cavity 22 needs to be replaced, the surface of the roller 33 is in contact with the polycarbonate tube. In this embodiment, a distance sensor 5 is included. The distance sensor 5 is installed on the bracket 32 ​​to measure the height of the replaced molding cavity 22. The height of the replaced molding cavity 22 is measured and the measured height is uploaded to the control terminal. The control terminal controls the switch of the electric push rod 31 according to the height. The height of the support assembly is the height of the molding cavity 22 plus the wall thickness of the molding cavity 22. In this way, even if the molding cavities 22 of different sizes are replaced to formulate polycarbonate tubes of different sizes, the utility model still meets the needs.

[0024] Furthermore, in order to improve the efficiency of the fan 41 and avoid wasting electricity resources, the air inlet of the fan 41 is aligned with the support assembly and installed on the upper end of the chassis 1.

[0025] Furthermore, in order for the operator to monitor the temperature inside the chassis 1 in real time and adjust the fan 41 and the switch of the vacuum pump connected to the molding cavity 22 in real time, a temperature detector is also installed on the inside of the chassis 1. The temperature detector is used to monitor the internal temperature of the chassis 1 in real time, and display the real-time temperature through a display screen connected thereto. The operator can observe the temperature inside the chassis 1 in real time based on the real-time temperature, and manually adjust the operating power of the fan 41 and the switch of the vacuum pump to meet the cooling needs and avoid the waste of electricity resources.

[0026] Furthermore, in order to locate the position of the polycarbonate tube outlet and to provide buffering for the polycarbonate tube after it exits the chassis 1, a sealing gasket is designed at the outlet in this embodiment. The sealing gasket can be a rubber ring, a metal ring or a plastic ring, as long as it meets the requirements of the utility model.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
