[0022] Embodiment 1
[0023] Such as Figure 1 - Figure 6As shown in the figure, a double-station plastic thermoforming machine includes a frame 1 and a fixing frame 2 installed on the top of the frame 1. Two positioning mechanisms are installed on the top of the frame 1. Among them, the positioning mechanism includes a processing groove 16 opened on the top of the frame 1, a lower clamping frame 18 installed on the top of the frame 1 and arranged around the processing groove 16, and an upper clamping frame 17 arranged on the top of the lower clamping frame 18 and used in cooperation with the lower clamping frame 18. A plurality of first air cylinders 19 are installed inside the frame 1 at the four corners of the upper clamping frame 17. The output end of the first air cylinder 19 passes through the frame 1 and the lower clamping frame 18 and is fixedly connected to the bottom of the upper clamping frame 17. A plastic thermoforming mechanism used in cooperation with the two positioning mechanisms is installed inside the frame 1. Among them, the plastic thermoforming mechanism includes a second air cylinder 22 and a vacuum pump 21 installed inside the frame 1, and a mold 20 installed at the output end of the second air cylinder 22. An air cavity is opened inside the mold 20, and a plurality of plastic thermoforming ports communicating with the air cavity are opened on the top of the mold 20. The vacuum pump 21 is communicated with the air cavity through a hose. A heating plate 4 and a heat dissipation box 5 located directly above the two positioning mechanisms are slidably arranged inside the fixing frame 2. A cooling box 23 is installed on the top of the heat dissipation box 5. Semiconductor refrigeration sheets 26 are installed on both inner walls of the cooling box 23. An installation hole is opened on the top of the cooling box 23, and a heat dissipation fan 25 is installed in the installation hole. The refrigerating surfaces of the two semiconductor refrigeration sheets 26 are arranged opposite to each other, and a cooling channel is formed inside the cooling box 23. A plurality of air outlet covers are installed at the bottom of the heat dissipation box 5. A plurality of air inlets are opened between the heat dissipation box 5 and the cooling box 23. A plurality of heat dissipation ports 24 are opened on both outer sides of the cooling box 23. The provided plurality of heat dissipation ports 24 facilitate the heat dissipation of the heating surface of the semiconductor refrigeration sheet 26. Two horizontally arranged first guide rods 7 located on both sides of the heating plate 4 are installed inside the fixing frame 2. First guide plates 6 sleeved outside the first guide rods 7 are installed on both sides of the heating plate 4. A third air cylinder 8 fixedly connected to the first guide plate 6 is installed on the side wall of the fixing frame 2. When it is necessary to drive the heating plate 4 to move, the third air cylinder 8 will drive the first guide plate 6 to move. Driven by the first guide plate 6, the heating plate 4 will move horizontally inside the fixing frame 2. Two horizontally arranged second guide rods 11 located on both sides of the heat dissipation box 5 are installed inside the fixing frame 2. Second guide plates 9 sleeved outside the second guide rods 11 are installed on both sides of the heat dissipation box 5. A fourth air cylinder 10 fixedly connected to the second guide plate 9 is installed on the side wall of the fixing frame 2. When it is necessary to drive the heat dissipation mechanism to move, the fourth air cylinder 10 will drive the second guide plate 9 to move. Under the action of the second guide plate 9, the heat dissipation box 5 will move left and right inside the fixing frame 2, so that the position of the heat dissipation box 5 can be adjusted.
[0024] It should be noted that for this double-station thermoforming machine, when in use, a plastic sheet is placed between the upper clamping frame 18 and the lower clamping frame 17. Multiple first air cylinders 19 will drive the upper clamping frame 18 to move downward to fix the plastic sheet between the upper clamping frame 18 and the lower clamping frame 17. Then, the heating plate 4 will move above the plastic sheet and heat the plastic sheet. After heating, the second air cylinder 22 will drive the mold 20 to move upward. While the mold 20 pushes the plastic sheet upward, the vacuum pump 21 will perform vacuum pumping work, and the heat-softened plastic sheet is adsorbed on the mold 20, thus completing the thermoforming work. After the thermoforming is completed, the heating plate 4 will move above another positioning mechanism to heat another plastic sheet. After heating, another thermoforming mechanism will perform thermoforming work according to the above operation method. In this way, through the two set positioning mechanisms and two thermoforming mechanisms, continuous staggered processing can be carried out, improving the processing efficiency. When the heating plate 4 moves above the plastic part to be thermoformed, the heat dissipation mechanism will move above the plastic part after blow molding. The heat dissipation fan 25 will blow external air into the interior of the cooling box 23. The air entering the interior of the cooling box 23 will be refrigerated by the semiconductor refrigeration sheet 26. The refrigerated air will enter the interior of the heat dissipation box 5 and then be blown onto the plastic part through multiple air outlet covers, thereby cooling the plastic part, increasing the forming speed of the plastic bottle, improving the working efficiency of this blow molding machine, avoiding the reduction of product quality caused by uneven forming, and ensuring the product quality.
[0025] Embodiment 2
[0026] As Figures 1-6 shown, the difference between this embodiment and Embodiment 1 is that: a feeding mechanism cooperating with the two positioning mechanisms is installed on one side of the frame 1, and a clamping mechanism cooperating with the two feeding mechanisms is installed on the other side of the frame 1. The feeding mechanism includes a feeding roller 27 installed on one side of the frame 1 and a guiding roller 28 installed on the top of the frame 1 and located on one side of the positioning mechanism. The feeding roller 27 is detachably installed on one side of the frame 1. The clamping mechanism includes a receiving box 12 installed on one side of the frame 1, two electric telescopic rods 13 installed on the inner wall of one side of the receiving box 12, a mounting plate 14 installed at the output ends of the two electric telescopic rods 13, and multiple pneumatic fingers 15 installed on one side of the mounting plate 14 and facing the frame 1. Two cutting knives 3 facing the receiving box 12 are installed at the bottom of the heating plate 4.
[0027] The further improvement of this embodiment lies in that during the use process, a plastic software to be processed is wound around the outside of the loading roller 27. The plastic software will bypass through the top of the guiding roller 28 and enter between the upper clamping frame 17 and the lower clamping frame 16, thus playing a certain guiding role. When the formed plastic part is cooled by the heat dissipation mechanism, the electric telescopic rod 13 will drive the pressing plate 14 to move towards the side close to the frame 1. The pneumatic finger 15 will clamp the plastic software, and under the drive of the electric telescopic rod 13, the formed plastic soft sheet will be pulled out from the positioning mechanism, and the plastic soft sheet to be formed will be moved to the top of the material receiving box 12. At this time, when the heating plate 4 moves to this plastic software again, the cutting knife 3 will cut the plastic software, and the formed plastic part will directly fall into the material receiving box 12. In this way, not only can the feeding be automatically carried out, but also the formed plastic parts can be automatically cut.
[0028] The above embodiments only represent several implementation modes of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the patent scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
