[0034] The specific configuration and functions of the replacement device 8 and the clamping device 9 will be described in detail below.

[0035] Reference Figure 3-Figure 6As shown, in this embodiment: the replacement device 8 includes a limit frame 83, the limit frame 83 is fixedly connected to the exhaust gas treatment box 4, the surface of the exhaust gas treatment box 4 is provided with a slide groove 89, the inner wall of the slide groove 89 is slidably connected to the activated carbon plate 81, the surface of the activated carbon plate 81 is fixedly connected to the handle 82, the inner wall of the limit frame 83 is slidably connected to the limit block 84, the limit block 84 is against the surface of the activated carbon plate 81, the inner wall of the limit frame 83 is fixedly connected to the spring 85, the other end of the spring 85 is fixedly connected to the limit block 84 By setting up a replacement device 8, the activated carbon plate 81 can be quickly replaced by using the mutual cooperation between the slide 89, the activated carbon plate 81, the handle 82, the limit frame 83, the limit block 84 and the spring 85. The design of this replacement device 8 makes it possible to use the activated carbon plate 81 for filtering the exhaust gas for a long time without affecting its normal adsorption effect. At the same time, it is convenient to treat the exhaust gas and reduce the pollution caused by the exhaust gas to the environment. The inner wall of the limit frame 83 is fixedly connected with a guide rod 86, and the guide rod 86 and the limit block 8 4 Sliding connection, the guide rod 86 is located in the spring 85, and the limit block 84 will squeeze the spring 85 along the arc surface of the guide rod 86. The guide rod 86 can prevent the spring 85 from deforming, thereby preventing the spring 85 from deforming and extending the service life of the spring 85, thereby stabilizing the performance of the spring 85. The surface of the limit block 84 is fixedly connected with a protrusion 88, and the protrusion 88 has the effect of increasing the friction force, thereby more conveniently pushing the limit block 84. The surface of the limit block 84 is fixedly connected with a fixing plate 87, and the fixing plate 87 is slidably connected to the limit frame 83. The movement of the limit block 84 will also drive the fixing plate 87 to slide along the surface of the limit frame 83. The fixing plate 87 can prevent dust or impurities from entering the limit frame 83, and prevent dust or impurities from entering the inner wall of the limit frame 83, which makes it difficult for the limit block 84 to slide, thereby improving the smoothness of the sliding of the limit block 84. At the same time, it can prevent dust or impurities from adhering to the surface of the spring 85 and corroding the spring 85, thereby further extending the service life of the spring 85.

[0036] Reference Figure 7 and Figure 8As shown, specifically, the clamping device 9 includes four rectangular holes 91, and the four rectangular holes 91 are respectively opened on the surface of the mold 11. The inner walls of the four rectangular holes 91 are slidably connected with sliders 92, and the surfaces of the four sliders 92 are slidably connected with fixing rods 93. The four fixing rods 93 are grouped in pairs, and one end of the two groups of fixing rods 93 is fixedly connected with a clamping plate 94, and the surfaces of the two clamping plates 94 are threadedly connected with screws 95. By setting the clamping device 9, the rectangular holes 91, the sliders 92, the guide rods 86, the clamping plates 94 and the screws 95 are mutually coordinated, and the plastic plate can be effectively positioned and clamped, which can avoid affecting the quality of the plastic plate after molding due to movement or shaking during the molding process. At the same time, it can also adapt to the plastic plates of different sizes for vacuum forming. Thereby improving the application scope of the blister forming machine, the surface of the slider 92 is rotatably connected with a ball 97, and the ball 97 is slidably connected to the inner wall of the rectangular hole 91. When the slider 92 slides, it will drive the ball 97 to rotate, and the ball 97 slides along the inner wall of the rectangular hole 91. The ball 97 can reduce the friction between the slider 92 and the rectangular hole 91, thereby driving the slider 92 to move more smoothly and conveniently. One end of the screw 95 is fixedly connected with a flexible pad 96, and the flexible pad 96 is against the inner wall of the mold 11. The flexible pad 96 is made of rubber. The movement of the screw 95 will drive the flexible pad 96 to move until the flexible pad 96 is against the inner wall of the mold 11. The flexible pad 96 can protect the inner wall of the mold 11 to prevent the screw 95 from directly contacting the mold 11 and causing wear.

[0037] Working principle: when using the mold 11 to vacuum-form the plastic plate, the plastic plate is placed in the mold 11, and then the electric telescopic rod 3 is started. The output end of the electric telescopic rod 3 will drive the long plate 13 to slide along the inner wall of the fixed frame 2, thereby driving the heating plate 12 to rise and fall, so that the height of the heating plate 12 can be adjusted so that the heating plate 12 covers the mold 11 in all directions, which is convenient for uniform heating and high-temperature softening of the plastic plate. Then the suction pump 5 is started to generate suction, and the suction pipe 6 will extract the gas in the mold 11, so that a negative pressure state is generated in the mold 11, so that the through holes opened on the surface of the mold 11 can absorb the softened plastic plate. When the suction pump 5 extracts the gas, the exhaust pipe 7 can discharge the waste gas extracted by the suction pump 5, and the waste gas will be discharged to the waste gas treatment box 4 When the exhaust gas enters the exhaust gas treatment box 4, it will first pass through the activated carbon plate 81. At this time, the exhaust gas is filtered by the activated carbon plate 81 and adheres to the surface of the activated carbon plate 81. Then, it is discharged through the ventilation holes opened on the surface of the exhaust gas treatment box 4 to complete the filtration of the exhaust gas. After long-term use of the activated carbon plate 81 to filter the exhaust gas, it is necessary to replace the activated carbon plate 81. First, the staff presses the protrusion 88, and then pushes the limit block 84 away from the handle 82. The protrusion 88 increases the friction force, thereby making it easier to push the limit block 84. The limit block 84 slides along the inner wall of the limit frame 83. At the same time, the limit block 84 will squeeze the spring 85 along the arc surface of the guide rod 86. The guide rod 86 can prevent the spring 85 from deforming and avoid the spring 85 is deformed, which can extend the service life of spring 85, thereby stabilizing the performance of spring 85. The movement of limit block 84 will also drive fixed plate 87 to slide along the surface of limit frame 83. Fixed plate 87 can prevent dust or impurities from entering limit frame 83, and prevent dust or impurities from entering the inner wall of limit frame 83, which makes limit block 84 difficult to slide, thereby improving the smoothness of sliding of limit block 84. At the same time, it can prevent dust or impurities from adhering to the surface of spring 85 and corroding spring 85, further extending the service life of spring 85. When limit block 84 is out of contact with activated carbon plate 81, handle 82 is pulled, and handle 82 drives activated carbon plate 81 to slide along the inner wall of slide groove 89, so that activated carbon plate 81 and slide groove 89 are in contact. The activated carbon plate 81 is disassembled by disengaging the contact, and then a new activated carbon plate 81 is installed in the exhaust gas treatment box 4. Then the worker's finger is disengaged from the protrusion 88, and the spring 85 begins to drive the limit block 84 to slide with its own elastic force. The limit block 84 is against the surface of the activated carbon plate 81, so that the position of the activated carbon plate 81 can be limited. By setting a replacement device 8, the activated carbon plate 81 can be quickly replaced by utilizing the mutual cooperation among the slide groove 89, the activated carbon plate 81, the handle 82, the limit frame 83, the limit block 84 and the spring 85. The design of this replacement device 8 ensures that the long-term use of the activated carbon plate 81 to filter the exhaust gas will not affect its normal adsorption effect, and it is convenient for the exhaust gas treatment.Reduce the pollution of exhaust gas to the environment.

[0038] When putting the plastic plate into the mold 11, the clamping device 9 is required to be used. First, pull the clamping plate 94, which will drive the fixing rod 93 to slide along the surface of the slider 92. At the same time, the fixing rod 93 can also drive the slider 92 to slide along the inner wall of the rectangular hole 91. When the slider 92 slides, it will drive the ball 97 to rotate, and the ball 97 slides along the inner wall of the rectangular hole 91. The ball 97 can reduce the friction between the slider 92 and the rectangular hole 91, thereby driving the slider 92 to move more smoothly and conveniently. When the clamping plate 94 is tightly fitted with the plastic plate, turn the screw 95, and the screw 95 moves with the help of the thread in the clamping plate 94. The movement of the screw 95 will drive the flexible pad 96 to move until the flexible pad 96 The flexible pad 96 rests against the inner wall of the mold 11 and can protect the inner wall of the mold 11 to prevent the screw 95 from directly contacting the mold 11 and causing wear. The heating plate 12 is then removed by bolts, and the staff then selects a suitable heating plate 12 and installs the heating plate 12 on the long plate 13. By setting the clamping device 9 and utilizing the cooperation between the rectangular hole 91, the slider 92, the fixing rod 93, the clamping plate 94 and the screw 95, the plastic plate can be effectively positioned and clamped, which can avoid affecting the quality of the plastic plate after molding due to movement or shaking during the molding process. At the same time, it can also adapt to plastic plates of different sizes for blister molding, thereby improving the application range of the blister molding machine.
