All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1 to 4 :

[0026] The utility model provides a blister tray cold resistance detection device, comprising: a detection table 1; vertical support columns are fixedly installed at the four corners of the bottom of the detection table 1; the four support columns stably support the detection table 1, and threaded grooves are respectively formed at the four corners of the top end of the detection table 1; clamping grooves are respectively formed at both ends of the detection table 1; a detection low-temperature box 2 is fixedly installed in the middle of the top end of the detection table 1, and a through pipe hole is formed at the right end of the detection low-temperature box 2; a through round hole is formed in the middle of the top end of the detection low-temperature box 2, and a circle of threaded grooves is formed at the edge of the round hole of the detection low-temperature box 2; a through electric push rod 3 is fixedly inserted into the round hole in the middle of the detection low-temperature box 2; a fixed hanging frame 4 is fixedly hung at the front end of the inner cavity top of the detection low-temperature box 2, and two grooves are formed in the middle of the fixed hanging frame 4; two screws are rotatably installed at the upper end of the fixed hanging frame 4, the screws on the fixed hanging frame 4 are rotatably installed on the top of the detection low-temperature box 2, and a perspective plate 401 is installed at the front end of the fixed hanging frame 4; the inspector can see clearly the temperature on the thermometer 402 through the perspective plate 401, and the cold resistance tolerance of the blister tray can be detected according to the temperature on the thermometer 402, and the thermometers 402 are respectively placed at the two grooves of the fixed hanging frame 4.

[0027] Among them, a sealed cover 201 is installed at the front opening of the low-temperature detection box 2, and symmetric handles are fixedly installed on the sealed cover 201. Grasping the handles on the sealed cover 201 facilitates opening and closing. A transparent observation window 202 is fixedly installed on the sealed cover 201. Through the observation window 202, the inspector can see the detection process in the low-temperature detection box 2. Symmetric clamping blocks 203 are fixedly installed at the bottom of the low-temperature detection box 2. When installing the low-temperature detection box 2, first insert the clamping blocks 203 into the card slots of the detection table 1, and then rotate and insert the screws on the fixed ear plates 204 into the threaded grooves of the detection table 1 to fix and limit the fixed ear plates 204 and the low-temperature detection box 2, preventing the low-temperature detection box 2 from being touched and shaken, which may affect the detection. Fixed ear plates 204 are respectively fixedly installed at the four corners of the outer end of the low-temperature detection box 2, and through screws are respectively rotatably inserted on the fixed ear plates 204. Parallel guide grooves 205 are respectively opened on the two side walls of the inner cavity of the low-temperature detection box 2, and parallel sliding grooves 206 are opened at the bottom of the inner cavity of the low-temperature detection box 2. A through injection pipe 207 is fixedly inserted at the pipe hole at the right end of the low-temperature detection box 2. Cold air enters the low-temperature detection box 2 from the injection pipe 207. At this time, the cold air will attack the plastic suction tray on the bearing box 209 to conduct a cold resistance test on the plastic suction tray. At the same time, the cold air will also contact the thermometer 402, and the temperature inside the low-temperature detection box 2 can be accurately known from the thermometer 402. Continuously inject cold air into the low-temperature detection box 2 to detect how low the cold resistance of the plastic suction tray is. A sealing ring 208 is fixedly installed in the middle of the top of the inner cavity of the low-temperature detection box 2. The sealing ring 208 seals the round hole in the middle of the top of the low-temperature detection box 2 to prevent cold air from leaking from the round hole at the top of the low-temperature detection box 2. A bearing box 209 is slidably installed at the bottom of the inner cavity of the low-temperature detection box 2, and a groove is opened in the middle of the upper end of the bearing box 209. Place the plastic suction tray in the groove at the upper end of the bearing box 209. Symmetric pull rings are fixedly installed on the front side wall of the bearing box 209. Grasping the pull rings on the bearing box 209 facilitates sliding back and forth. Parallel sliding strips 210 are fixedly installed at the bottom of the bearing box 209, and the sliding strips 210 are slidably installed in the sliding grooves 206. When the bearing box 209 slides back and forth, the sliding strips 210 are restricted by the sliding grooves 206, and the bearing box 209 can only slide back and forth, preventing the bearing box 209 from shifting or tilting when sliding back and forth, so that the bearing box 209 cannot smoothly enter the low-temperature detection box 2 and affect the detection.

[0028] Among them, a stabilizing plate 301 is fixedly installed on the annular side wall of the electric push rod 3. A circle of screws is rotatably inserted at the edge of the stabilizing plate 301. The screws on the stabilizing plate 301 are rotatably inserted into the threaded grooves at the top end of the low-temperature detection box 2 to fix and limit the stabilizing plate 301 and the electric push rod 3. A mold frame 302 is fixedly installed at the lower end of the electric push rod 3. A fixing groove is formed in the middle of the bottom of the mold frame 302. Guide blocks 303 that are parallel to each other are fixedly installed on the two side walls of the mold frame 302 respectively. The guide blocks 303 are slidably installed in the guide grooves 205. When the mold frame 302 slides up and down, the guide blocks 303 are restricted by the guide grooves 205, and the mold frame 302 can only slide up and down, preventing the mold frame 302 from tilting when sliding up and down, so that the detection block 305 at the lower end of the mold frame 302 cannot accurately press down on the plastic suction tray for detection. A detection plate 304 is installed at the fixing groove at the bottom of the mold frame 302. Detection blocks 305 are evenly fixedly installed at the bottom of the detection plate 304. The detection blocks 305 are made of soft neutral materials. Use the electric push rod 3 to push the mold frame 302 downward. At this time, the detection blocks 305 at the lower end of the mold frame 302 will also slide downward. When the detection blocks 305 press down on the plastic suction tray, it can be seen through the observation window 202 whether the plastic suction tray can withstand the pressure after being exposed to cold, so that the cold resistance of the plastic suction tray can be accurately detected.

[0029] Embodiment 2, on the basis of Embodiment 1, as Figure 1 and Figure 4 shown, fixing ear plates 204 are fixedly installed at the four corners of the outer end of the low-temperature detection box 2 respectively. Through screws are rotatably inserted through the fixing ear plates 204. Delete all parts such as the fixing ear plates 204 and the screws, and then fixedly weld the bottom of the low-temperature detection box 2 to the detection table 1 to stably limit the low-temperature detection box 2. In this way, the low-temperature detection box 2 will not shake when touched, affecting the detection, thus avoiding the problem of loosening of the screws after long-term use and saving the cost of parts at the same time.

[0030] The working principle of this embodiment: When in use, place the plastic suction tray in the groove at the upper end of the carrier box 209. Cold air enters the low-temperature detection box 2 from the injection pipe 207. At this time, the cold air will attack the plastic suction tray on the carrier box 209 to perform a cold resistance test on the plastic suction tray. At the same time, the cold air will also contact the thermometer 402, and the temperature inside the low-temperature detection box 2 can be accurately known from the thermometer 402. According to the temperature on the thermometer 402, the cold resistance tolerance of the plastic suction tray can be detected. Continuously inject cold air into the low-temperature detection box 2 to detect how low the cold resistance the plastic suction tray can withstand. Use the electric push rod 3 to push the mold frame 302 downward. At this time, the detection blocks 305 at the lower end of the mold frame 302 will also slide downward. When the detection blocks 305 press down on the plastic suction tray, it can be seen through the observation window 202 whether the plastic suction tray can withstand the pressure after being exposed to cold, so that the cold resistance of the plastic suction tray can be accurately detected.
