Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic products, especially an intelligent detection temperature control device for comb production line. BACKGROUND

[0002] Combs are important tools for people to manage hair, which are frequently used in daily life and in the beauty industry, and have a high demand, especially disposable combs made of plastic, which generally adopt injection molding process, have large production capacity and are simple to manufacture. However, since the end of the comb has a large number of teeth, accurate regulation of the injection temperature during the injection molding process is crucial, which directly relates to the quality of the injection molded product. Currently, the injection molding machines commonly seen on the market mainly adopt two temperature control methods: open-loop control and closed-loop control. The open-loop control regulates the temperature by presetting the heating time and power, which is simple to operate and has low cost, and is very suitable for injection molding of products with relatively simple shapes. However, the temperature control precision is limited, and it is not suitable for combs with a large number of teeth. In contrast, the closed-loop control regulates the temperature by real-time monitoring of the temperature with a temperature sensor and feeding back to the controller for accurate adjustment. This method can significantly improve the precision and stability of temperature control. However, the closed-loop control also has higher cost, and the sensor inside is too close to the high-temperature masterbatch, which causes easy contamination and difficulty in replacement, affecting the stability of use. To ensure that the teeth of the comb can be uniformly formed, Chinese patent document CN202110756956.4 discloses a multi-cavity full-automatic demolding injection molding mold, which comprises an injection molding machine body and a mold. The inside of the injection molding machine body is provided with a mold. The surface of the mold is provided with uniformly arranged cavities, which are comb-shaped structures. The cavity on the surface of the mold contains all the tooth parts of the comb. The parting line of the product made by the male membrane and the female membrane of the mold is located at the non-tooth position of the comb. The above-mentioned patent improves the surface quality of the tooth position of the comb through the special cavity design, and greatly facilitates the processing of burrs. However, the design of the special cavity still needs to set multiple sensors for temperature control, and the installation position of the sensor in the special cavity is difficult, which easily affects the detection of the sensor.

[0003] Therefore, it is necessary for those skilled in the art to provide an intelligent detection temperature control device for comb production line, which ensures the stability and accuracy of the sensor, prevents the adhesion of high-temperature masterbatch, and is convenient to replace, thereby improving the production stability.

[0023] The utility model sets up the temperature sensor above the mould, so that the temperature sensor cannot be in contact with the mould, thereby preventing the high-temperature master batch in the mould from being bonded, and facilitating replacement and maintenance, and improving use stability.

[0024] Further, referring to Figure 3 , the installation plane 12 is also provided with a temperature control device 20, and the temperature control device 20 is electrically connected between the sensor 16.

[0025] In use, the temperature of the mold is detected by the sensor 16, and the air temperature is adjusted by the temperature adjustment box 21 according to the set temperature, and then the adjusted air is introduced into the pipeline 23, and finally discharged from the exhaust box 22 and sprayed onto the positioning block 13, so as to realize the temperature adjustment of the mold located on the positioning block 13.
