[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0027] like Figure 1-4As shown, the utility model provides a cooling device for a blister forming machine, including a lower mold base 1, a blister forming lower mold 2 is fixedly installed on the middle part of the top of the lower mold base 1, an upper mold base 3 is slidably connected to the top of the lower mold base 1, and a blister forming upper mold 4 is fixedly installed on the bottom of the upper mold base 3, and a cooling device 5 is fixedly installed on the left and right sides of the top of the lower mold base 1, and a cooling coil 21 is fixedly installed on the left and right sides of the inside of the blister forming lower mold 2, and both ends of the cooling coil 21 respectively penetrate to the front and back sides of one side of the blister forming lower mold 2 close to the cooling device 5 and are fixedly connected to a connecting mechanism 22, and the cooling device 5 comprises a cooling box 51, and the two cooling boxes 51 are respectively fixedly installed on the left and right sides of the top of the lower mold base 1, and the inner surface of the cooling box 51 is fixedly connected to a semiconductor refrigeration plate 52 on the side away from the blister forming lower mold 2. The semiconductor refrigeration plate 52 can be used to conduct heat in the coolant to achieve continuous cooling of the mold, and the end of the semiconductor refrigeration plate 52 away from the blister forming lower mold 2 penetrates to the outer surface of the cooling box 51, and the cooling box 51 is close to the lower front side of the side of the blister forming lower mold 2. The two ends of the back are fixedly connected with a conducting pipe 53, which is fixedly installed on the side of the connecting mechanism 22 away from the lower mold 2 of the blister. A blowing groove 56 is opened on the front and back sides of the upper interior of the cooling box 51, and a dustproof net 57 is fixedly connected to the left and right ends of the inner surface of the blowing groove 56. A connecting frame 58 is fixedly connected to the middle of the inner surface of the blowing groove 56. A motor 59 is fixedly installed in the middle of the connecting frame 58. The output shaft of the motor 59 is fixedly connected to the cooling fan 510. The conducting pipe 53 is away from the side of the lower mold 2 of the blister. The end passes through the interior of the cooling box 51 and the outer surface is fixedly connected to the connecting shell 54. The middle part of the top of the connecting shell 54 is rotatably connected to the transmission shaft 55. The top of the transmission shaft 55 passes through the interior of the blowing slot 56 and is fixedly connected to the bevel gear 2 512.

The bottom end of the transmission shaft 55 passes through the interior of the connecting shell 54 and is fixedly connected to the guide fan 551.

[0028] When the blister mold and the processed workpiece in the blister machine are quickly cooled, the motor 59 is started to drive the air-cooling fan 510 to rotate, thereby driving air to circulate inside the blowing slot 56, so that the blister lower mold 2 and the processed workpiece can be cooled by air. At the same time, the rotation of the air-cooling fan 510 can also drive the bevel gear 1 511 to rotate, thereby driving the transmission shaft 55 to rotate through the bevel gear 2 512, so that the guide fan 551 can rotate inside the conduction pipe 53 and the connecting sleeve 54, and can drive the coolant in the cooling box 51 to flow in the conduction pipe 53, and can circulate in the cooling coil 21, thereby realizing water-cooling of the blister mold and the processed workpiece, making the cooling effect of the blister mold and the processed workpiece better, and improving the processing efficiency of the paper-plastic packaging box.

[0029] like Figure 5-6 As shown, the utility model provides a cooling device for a blister forming machine, wherein one end of the guide tube 53 close to the lower blister forming mold 2 is fixedly connected to a plug-in tube 531, and an annular groove 532 is provided on the outer surface of the plug-in tube 531, and the connecting mechanism 22 comprises a sleeve ring 221, and the two sleeve rings 221 are fixedly connected to the front and rear ends of the cooling coil 21 respectively, and the plug-in tube 531 is slidably plugged into the inner surface of the sleeve ring 221, and the outer surface of the sleeve ring 221 is slidably connected to the sliding ring 222, and the inner surface of the sliding ring 222 is fixedly connected to the sliding pull block 223 on both the upper and lower sides. The inner upper and lower sides of the sleeve ring 221 are provided with a sliding groove that penetrates inside and outside, and the middle part of the sliding pull block 223 is slidably connected to the guide column 224 that penetrates left and right. The left and right ends of the guide column 224 are fixedly connected to the left and right sides of the inner wall of the sliding groove respectively, and the outer surface of the guide column 224 is provided with a tightening spring 225. The cam 228 is fixedly connected to the side of the sliding block 223 close to the lower blister mold 2. The interior of the sliding block 223 is movably connected with a transmission wheel 226 that passes through it from front to back. The rear side of the outer surface of the transmission wheel 226 is meshed with a transmission rack 227. The transmission rack 227 is fixedly connected to the rear surface of the sliding groove. The opposite surfaces of the two transmission wheels 226 are fixedly connected with a transmission screw 228. The transmission screw 228 passes through the outside of the sliding block 223 and is threadedly connected with a threaded slide 229 on the outer surface. The outer surface of the threaded slide 229 is slidably connected with a fixed sleeve 2210. The outer surface of the fixed sleeve 2210 is slidably connected to the inner surface of the sliding groove and the end away from the transmission screw 228 passes through the inside of the annular groove 532. A limiting slide is provided on the inner surface of the fixed sleeve 2210. The outer surface of the threaded slide 229 is fixedly connected to a limiting slide, and the limiting slide is slidably connected to the inside of the limiting slide.

[0030] When the cooling device is in use, by pulling the sliding ring 222 to slide, the sliding pull block 223 can slide along the guide column 224, so that the transmission wheel 226 can drive the transmission screw 228 to rotate synchronously through the engagement between the transmission wheel 226 and the transmission rack 227, thereby driving the threaded slide plate 229 to slide to the inside of the sliding groove and pulling the fixed sleeve 2210 back, so as to facilitate the insertion of the plug-in tube 531 into the interior of the sleeve ring 221, and then loosening the sliding ring 222. Under the push of the tightening spring 225, the sliding pull block 223 can be reset, and the fixed sleeve 2210 can be reset, so that the fixed sleeve 2210 can be stuck in the inside of the annular groove 532, thereby realizing the connection and fixation of the conducting tube 53, completing the connection between the lower blister mold 2 and the cooling device 5, making the use of the cooling device 5 more convenient.

[0031] The following is a detailed description of the working principle of the cooling device of the blister machine.

[0032] like Figure 1-6 As shown, when the blister mold and the workpiece in the blister machine are rapidly cooled, the sliding pull block 223 slides smoothly along the guide column 224 through the pull of the sliding ring 222, and then the transmission wheel 226 and the transmission rack 227 are precisely engaged to drive the transmission screw 228 to rotate synchronously. This process causes the threaded slide 229 to slide to the inside of the sliding groove and pull the fixed sleeve 2210 back, so that the plug-in tube 531 can be easily inserted into the sleeve ring 221. Subsequently, the sliding ring 222 is released, and the tightening spring 225 automatically resets the sliding pull block 223, driving the fixed sleeve 2210 back to its position, ensuring that it is stuck in the annular groove 532, thereby firmly connecting the conducting tube 53. , achieving a close connection between the blister lower mold 2 and the cooling device 5, then starting the motor 59, the air-cooling fan 510 rotates efficiently, driving the air to circulate in the blowing slot 56, and implementing air cooling and cooling for the blister lower mold 2 and the processed workpiece. At the same time, the rotation of the air-cooling fan 510 also links the rotation of the bevel gear 1 511, and transmits power to the transmission shaft 55 through the bevel gear 2 512, driving the guide fan 551 to rotate in the conducting pipe 53 and the connecting sleeve 54, promoting the coolant in the cooling box 51 to circulate in the conducting pipe 53 and the cooling coil 21, providing water cooling for the blister mold and the processed workpiece, significantly improving the cooling effect, and thereby speeding up the processing speed of the paper-plastic packaging box.

[0033] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
