DETAILED DESCRIPTION
[0027] The following is combined with Figure 1-5 This application is described in further detail.
[0028] A hand-shaped mold with temperature monitoring, referring to Figure 1 As shown, the hand-shaped mold array is installed in the polymer material infiltration film forming product production line. The hand-shaped mold moves along the line of the product production line and passes through each production process one by one.
[0029] In this example, the production of polymer film-forming products using gloves as an example is described. Glove production involves a series of steps: hot rinsing of hand-shaped molds, coagulant impregnation, coagulant baking, primary dipping, primary baking, secondary dipping, secondary baking, polymer solution impregnation, primary oven baking, cooling tank, neutralization tank, chlorine washing, laminating machine inspection, and demolding. This repetitive process completes the production of gloves.
[0030] Among the above production processes, the hand mold needs to be heated during hot rinsing, kept warm during coagulant impregnation, coagulant baking, primary dipping, primary baking, secondary dipping, and secondary baking. The hand mold needs to be cooled before entering the polymer solution during the secondary baking. During the main furnace baking, the hand mold needs to be quickly heated and then kept warm. Heating is not required in the cooling tank, neutralization tank, chlorine washing, or laminating machine. Therefore, it is necessary to monitor the temperature value, temperature changes, and the duration of temperature changes for each production process.
[0031] Reference Figure 2 and Figure 3As shown, the hand-shaped mold in the present application includes a mold body 1 and a temperature monitoring device 2 arranged in the mold body 1. The temperature monitoring device 2 includes a plurality of temperature sensing sheets 21 and a collection component. The plurality of temperature sensing sheets 21 and the collection component are all arranged in the mold body 1. The temperature sensing sheet 21 has a built-in temperature sensing resistor. The temperature sensing sheet 21 can collect temperature data. The plurality of temperature sensing sheets 21 are fitted on the inner wall of the mold body 1, specifically at the palm position of the mold body 1, and multiple temperature sensing sheets 21 are scattered at various positions of the palm of the mold body 1. The temperature sensing sheets 21 can be fitted and fixed by gluing.
[0032] Reference Figure 3 、 Figure 4 and Figure 5 As shown, the acquisition component includes an acquisition shell 22, and a controller and a wireless communicator arranged in the acquisition shell 22. Several temperature sensing plates 21 are connected to the controller through conductive lines 23, and the wireless communicator is connected to the controller. The wireless communicator is also connected to the host computer through wireless communication. The host computer is a terminal device arranged outside the polymer material infiltration and film-forming product production line.
[0033] The hand molds are installed in the production line, and the temperature monitoring devices 2 can be installed at intervals between the hand molds. To record the hand molds to which the temperature monitoring devices 2 are installed, RFID chips can be installed on the hand molds. Each RFID chip records the serial number of each hand mold. A positioning card reader for reading the RFID chips is installed at the starting position of each production process, thereby determining the position of the production process in which the hand mold is located. The RFID chips can be passive or active, and this embodiment does not specifically limit this.
[0034] Thus, the hand-shaped mold follows the product production line through the entire production process of each production step, such as tunnel drying, dipping, water washing, acid and alkali washing, etc. When the hand-shaped mold enters the starting position of the tunnel drying production process, the positioning card reader reads the RFID chip to obtain the number information of the hand-shaped mold, and it can be known that the hand-shaped mold has entered the tunnel drying production process. Then, the temperature data of the mold body 1 is collected through the temperature measuring sensor 21. The controller converts the obtained temperature data and sends it to the host computer through the wireless communicator. The host computer can organize and analyze all the collected temperature data, and then obtain the real-time temperature value, temperature change and temperature change time of the production process.
[0035] The data acquisition housing 22 is provided with a battery compartment for installing a power supply battery, which is used to provide the power required by the controller, the temperature sensor 21, and the wireless communicator. The battery compartment is provided on the surface of the data acquisition housing 22, so that the power supply battery in the battery compartment can be easily replaced.
[0036] The mold body 1 needs to undergo tunnel drying, glue dipping, water washing, acid and alkali washing, etc., so the collection component needs to be better protected. In this application, a built-in box 3 is provided in the mold body 1, and the collection shell 22 is provided in the built-in box 3. Several temperature measuring sensors 21 are led out of the built-in box 3 through the conductive wire 23, and several temperature measuring sensors 21 are respectively fitted at the palm position of the mold body 1.
[0037] The built-in box 3 is made of a polymer inorganic material to prevent it from shielding the electromagnetic signals from the collection components. It comprises a lower box body 31 and an upper box body 32. The upper end of the lower box body 31 is provided with a snap-fit mounting edge 33, and the lower end of the upper box body 32 is provided with a snap-fit mounting groove 34 adapted to fit the snap-fit mounting edge 33. The wall of the snap-fit mounting edge 33 is provided with a rubber layer to improve the sealing between the upper box body 32 and the lower box body 31.
[0038] In this embodiment, the collection assembly is disposed within the built-in box 3, which can be housed in either the upper box body 32 or the lower box body 31. The collection housing 22 is provided with mounting ears 24, which can be secured to the built-in box 3 via screws. A through-hole 35 is provided at the bottom of the lower box body 31, through which the temperature sensing chip 21 and the conductive wire 23 are led. A rubber plug 25 is provided on the collection housing 22 to seal the through-hole 35, through which the conductive wire 23 is led. A window 4 is provided in the mold body 1. The top edge of the upper box body 32 is flush with the bottom edge of the window 4, and the top of the upper box body 32 is raised in the middle. The provision of window 4 relieves the electromagnetic wave shielding effect of the metal seal, facilitating the transmission of wireless signals. Furthermore, when water enters the mold body 1, the water flows from the top of the upper box body 32 to the edge and is discharged through the window 4.
[0039] In this embodiment, the built-in box 3 is embedded in the inner cavity of the mold body 1, and the outer wall of the built-in box 3 is in close contact with the inner cavity of the mold body 1, thereby realizing the installation and fixation of the built-in box 3 in the inner cavity of the mold body 1. In order to improve the sealing between the built-in box 3 and the inner cavity of the mold body 1, sealant is filled between the top edge of the built-in box 3 and the inner wall of the mold body 1, and a sealing groove is circumferentially arranged on the outer wall surface of the upper box body 32, and a sealing ring 5 is arranged in the sealing groove.
[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
