[0021] In one embodiment, please refer to Figures 1 to 5As shown in the figure, a plastic cup thermoforming device provided by the present invention includes an upper template group 1 and a lower template group 2. The lower template group 2 is provided with a forming cavity and is used to accommodate the plastic sheet to be formed.

[0022] An upper die sleeve 3 adapted to the forming cavity is installed in the upper template group 1. The upper die sleeve 3 can slide vertically to achieve the closing and separation from the forming cavity.

[0023] A sleeve rod 4 extending into the forming cavity is slidably installed on the upper template group 1. A die core 5 disposed in the forming cavity is fixed at the bottom end of the sleeve rod 4. The die core 5 precisely adapts to the shape of the forming cavity to ensure the forming accuracy.

[0024] A cooling flow channel communicating with the outside is opened in the upper template group 1 for circulating the cooling medium. Among them, the cooling flow channel is communicated with the external cooling medium circulation system.

[0025] The upper template group 1 includes: A first cooling air duct 11 is opened in the upper template group 1 and has an air inlet and a plurality of air outlets 12. Among them, the first cooling air duct 11 is communicated with an external air cooling device, and the air cooling device is used to provide cooling gas.

[0026] An image acquisition component 6 has an image housing 61 slidably installed at the air outlet 12. The image housing 61 can move along the sliding direction of the upper die sleeve 3 and can rotate along the central line direction of the upper die sleeve 3. A second cooling air duct 62 communicating with the first cooling air duct 11 is opened in the image housing 61. An image acquisition module 63 for acquiring the image of the end of the upper die sleeve 3 is fixed in the image housing 61. A plurality of air outlet holes 64 communicating with the second cooling air duct 62 are opened on the outer peripheral wall of the image housing 61, and the air outlet holes 64 are arranged towards the cutting edge of the upper die sleeve 3.

[0027] The working principle of the present invention: S1: Place the heated and softened plastic sheet in the forming cavity of the lower template group 2. The upper die sleeve 3 and the die core 5 are in the initial position. The upper template group 1 and the lower template group 2 move relatively in the same direction and close with the forming cavity. Through the vacuum adsorption effect, the plastic sheet is attached to the surface of the die core 5 and the forming cavity to form the shape of the cup body. S2: The upper template group 1 and the lower template group 2 continue to move relatively in the same direction. The upper die sleeve 3 abuts against the end of the forming cavity to cut off the cup body. S3: After the cup body is formed, the upper template group 1 and the lower template group 2 move relatively in the opposite direction, and the cup body is blown out from the forming cavity. S4: The image housing 61 moves downward until it reaches the set position and then rotates. The air-cooling device operates, and the cooling air flow passes through the first cooling air duct 11 and the second cooling air duct 62, and is ejected from the air outlet hole 64 to cool the cutting edge of the upper die sleeve 3. At the same time, the image acquisition module 63 acquires the image of the cutting edge of the upper die sleeve 3 and transmits the data to the operator.

[0028] Generally speaking, in this example, the cutting edge of the upper die sleeve 3 is cooled through the first cooling air duct 11 and the second cooling air duct 62, which avoids the heat accumulation on the cutting edge of the upper die sleeve 3 after long-term use, improves the service life of the upper die sleeve 3. At the same time, an integrated design is adopted, and the image acquisition module 63 is arranged at the air outlet 12 to monitor the image of the cutting edge of the upper die sleeve 3 in real time, enabling the operator to adjust relevant parameters in time, avoiding defective products, improving the quality stability of the products, and being able to trace the root cause of product quality problems, providing data support for the optimization of process parameters, and promoting the intelligent upgrade of production.

[0029] In an alternative example, please refer to Figures 1 to 7 As shown, the image housing 61 includes a rotating housing 611 and a telescopic housing 612. The rotating housing 611 is installed in the upper template set 1 by rotation, and the telescopic housing 612 is installed in the rotating housing 611 by sliding and can slide vertically. The second cooling air duct 62 is arranged in the telescopic housing 612. A plurality of air guiding through grooves 613 are formed on the outer wall of the telescopic housing 612, and the air guiding through grooves 613 can communicate with the first cooling air duct 11. The image acquisition module 63 is fixed in the telescopic housing 612 and passes through the rotating housing 611. Among them, an installation cavity 13 is arranged in the upper template set 1, and the rotating housing 611 is inserted into the installation cavity 13 by means of bearing connection. The air outlet 12 is opened at the bottom of the upper template set 1 and communicates with the installation cavity 13, and the telescopic housing 612 can move in the air outlet 12.

[0030] Specifically, in this example, the rotating housing 611 can rotate at multiple angles, realizing the full-round detection of the cutting edge, facilitating the maintenance and replacement of the upper die sleeve 3, and ensuring the stability of the upper die sleeve 3 through the cooperation of the air guiding through grooves 613 and the first cooling air duct 11.

[0031] In an alternative example, please refer to Figures 1 to 8As shown, an observation port 6121 is provided on the outer wall of the telescopic housing 612. The image acquisition module 63 includes an optical component 631. The optical component 631 has a lens for acquiring images. The lens is disposed at the observation port 6121. The air outlet holes 64 are arranged in an annular array centered on the lens and are disposed toward the cutting edge of the upper die sleeve 3. Among them, the image acquisition module 63 includes a reflector 632 and a sensor 633. After the light passes through the lens first and then through the refraction of the reflector 632, it reaches the surface of the sensor 633. The reflector 632 can effectively reduce the volume of the telescopic housing 612 in the horizontal direction and ensure the forming quantity of the plastic cups.

[0032] Specifically, in this example, the camera and the cooling path are concentrically designed, and a single structure realizes the dual functions of cooling and monitoring, effectively reducing the manufacturing difficulty and production cost of the plastic cup thermoforming device.

[0033] In an alternative example, please refer to Figures 1 to 8 As shown, a wind guiding ring 614 is fixed at the observation port 6121 by bonding. The air outlet 12 is provided on the wind guiding ring 614. A sealing ring 615 sleeved on the outer wall of the lens is provided at one end of the wind guiding ring 614 facing the second cooling air duct 62. A diversion groove 616 facing the lens direction is provided on the inner wall of the wind guiding ring 614.

[0034] Specifically, in this example, through the synergistic action of the wind guiding ring 614 and the diversion groove 616, the cooling air flow forms an "annular air curtain" along the surface of the lens, effectively taking away the heat of the lens and the cutting edge, avoiding local overheating. And the wind guiding ring 614 is of a detachable design, which is convenient for quickly cleaning or replacing the sealing ring 615, reducing the maintenance time. The diversion groove 616 can divert part of the gas toward the lens direction to clean the lens direction and ensure the image acquisition accuracy.

[0035] In an alternative example, please refer to Figures 1 to 8 As shown, the telescopic housing 612 includes an annular housing 6122. The upper end of the annular housing 6122 is fixed with a top ring cover 6123 by bolt connection. The lower end of the annular housing 6122 is fixed with a bottom end cover 6124 by bolt connection.

[0036] Specifically, in this example, by splitting the telescopic housing 612 into the structure of the annular housing 6122, the top ring cover 6123 and the bottom end cover 6124, the manufacturing difficulty and assembly difficulty of the telescopic housing 612 are effectively reduced, and the disassembly and assembly efficiency of the telescopic housing 612 is improved.

[0037] In an alternative example, please refer to Figures 1 to 9As shown, a sliding groove 6111 is formed on the inner wall of the rotating housing 611. At least one guiding strip 6112 is formed on the inner wall of the sliding groove 6111. A first limiting flange 6113 extending towards the inside of the sliding groove 6111 is arranged at the bottom of the sliding groove 6111. A second limiting flange 61221 extending outwards is arranged on the outer wall of the annular housing 6122. A guiding groove 61222 adapted to the guiding strip 6112 is formed on the outer wall of the second limiting flange 61221. Wherein, the first limiting flange 6113 and the second limiting flange 61221 can abut against each other to limit the vertical movement of the annular housing 6122. When the annular housing 6122 slides, the guiding strip 6112 is inserted into the guiding groove 61222 to ensure the accuracy and stability of the movement track.

[0038] Specifically, in this embodiment, by adding the sliding groove 6111, the guiding strip 6112 and the limiting structure, the telescopic housing 612 not only realizes a reliable axial telescopic function, but also ensures the stability and safety of the movement through precise guiding and two-way limiting.

[0039] In an alternative example, please refer to Figures 1 to 11 As shown, an electromagnetic module 65 is fixed to one end of the rotating housing 611 facing away from the telescopic housing 612 by means of bolt connection. The electromagnetic module 65 has a magnetic attraction end 651 that generates magnetic force through electricity. The top ring cover 6123 is made of a magnetic conductive material and can move towards the electromagnetic module 65 by magnetic force. Wherein, the rotating housing 611 has a hollow cylindrical structure. Both the rotating housing 611 and the telescopic housing 612 are made of non-magnetic conductive materials, such as aluminum alloy, plastic, etc., to avoid the influence of magnetic force on the rotation of the rotating housing 611. When the electromagnetic module 65 is powered on, the coil generates a magnetic field, and the magnetic attraction end 651 exerts an attractive force on the top ring cover 6123 to make it move in the direction towards the electromagnetic module 65.

[0040] Specifically, in this embodiment, the top ring cover 6123 is driven to move by electromagnetic force, without a complex mechanical transmission mechanism, and can realize remote control and precise displacement adjustment, reducing the manufacturing difficulty of the image acquisition component 6. At the same time, the electromagnetic module 65 is directly integrated at the end of the rotating housing 611, reducing the space occupation and manufacturing cost of the image acquisition component 6.

[0041] In an alternative example, please refer to Figures 1 to 11As shown, a sliding electromagnetic ring 7 is fixed inside the upper template group 1. The rotating end of the sliding electromagnetic ring 7 is fixedly connected to the electromagnetic module 65. The image acquisition module 63 passes through the sliding electromagnetic ring 7 and extends out of the sliding electromagnetic ring 7. A spring 8 is arranged inside the rotating housing 611. The spring 8 is sleeved on the outer wall of the image acquisition module 63. One end of the spring 8 abuts against the top ring cover 6123, and the other end of the spring 8 abuts against the rotating end of the sliding electromagnetic ring 7. When the electromagnetic module 65 is powered off, the spring 8 pushes the sliding electromagnetic ring 7 and the top ring cover 6123 to reset, ensuring the stability of the system. The fixed end of the sliding electromagnetic ring 7 is fixedly connected to the upper template group 1. The sliding electromagnetic ring 7 is connected to an external power supply device and is used to provide current.

[0042] Specifically, in this example, through the combined design of the sliding electromagnetic ring 7 and the spring 8, the accuracy, dynamic stability and environmental adaptability of electromagnetic regulation are realized, and the manufacturing difficulty and manufacturing cost of the image acquisition module 63 are reduced.

[0043] In an alternative example, please refer to Figures 1 to 11 As shown, a puncturing part 6125 is arranged at one end of the telescopic housing 612 facing the lower template group 2. A receiving groove 21 is formed at one end of the lower template group 2 facing the upper template group 1. The puncturing part 6125 is conical and is arranged at the lower end of the bottom end cover 6124. The depth of the receiving groove 21 matches the maximum extended length of the puncturing part 6125 to ensure that no interference occurs with other structures of the lower template group 2 when the puncturing part 6125 is fully inserted.

[0044] Specifically, in this example, through the puncturing part 6125, when the telescopic housing 612 moves downward, it can puncture the plastic film, avoiding pulling the plastic film and affecting the forming of the plastic cup body.

[0045] In an alternative example, please refer to Figures 1 to 11 As shown, the image acquisition component 6 includes a driving module. The driving module includes a driving motor 91 installed inside the upper template group 1. A driving gear 92 is fixedly connected to the output shaft of the driving motor 91 by key connection. An outwardly extending extension flange 6114 is arranged on the outer wall of the rotating housing 611. A number of driven teeth 6115 are formed on the outer wall of the extension flange 6114. The driven teeth 6115 are arranged in a ring shape with the rotation center of the rotating housing 611 as the center line. The driving gear 92 meshes with the driven teeth 6115. The driving motor 91 is installed in the installation cavity 13 by bolt connection. When the driving motor 91 is powered on, the output shaft drives the driving gear 92 to rotate, and through the meshing transmission between the gear teeth and the driven teeth 6115, the rotating housing 611 is driven to rotate around its axis.

[0046] Specifically, in this example, core components such as an image sensor 633 and a lens are installed inside the rotating housing 611. Its rotational movement is precisely controlled by a drive module to achieve multi-angle or continuous scanning image acquisition. Moreover, the extended flange 6114 and the driven gear 6115 are integrally designed. In cooperation with the annular extended flange 6114, it saves internal space, reduces the device volume of the image acquisition component 6, and ensures the forming quantity of plastic cups.

[0047] Generally speaking, in the present invention, the cutting edge of the upper die sleeve 3 is cooled by the first cooling air duct 11 and the second cooling air duct 62, which avoids the heat accumulation on the cutting edge of the upper die sleeve 3 after long-term use, improves the service life of the upper die sleeve 3. At the same time, an integrated design is adopted, and the image acquisition module 63 is arranged at the air outlet 12 to monitor the image at the cutting edge of the upper die sleeve 3 in real time, enabling the operator to adjust relevant parameters in a timely manner, avoiding defective products, and improving the product quality stability. In addition, core components such as an image sensor 633 and a lens are installed inside the rotating housing 611. Its rotational movement is precisely controlled by a drive module to achieve multi-angle or continuous scanning image acquisition, saves internal space, reduces the device volume of the image acquisition component 6, and ensures the forming quantity of plastic cups.
