[0021] During the use of the melting equipment, a melting temperature control device is required. The melting temperature control device provided by the utility model is specifically used to achieve temperature control in the melting process to prevent the molten plastic from being affected by the residual heat of the heating equipment and causing excessive melting. At the same time, it prevents the molten plastic from contacting with the air and causing contamination and rapid cooling. During the use of this device, it is necessary to carry out inspections and other preparatory work in advance to ensure the normal operation of the device.

[0022] Please refer to the attached Figure 1 -Attached Figure 4 A melting temperature control device for plastics includes a base 1, a melting box 2 is fixed to the top surface of the base 1, a temperature control shell 101 is fixed to the top surface of the base 1, a sealing cover 102 is threadedly connected to the top surface of the temperature control shell 101, a temperature control component is arranged inside the temperature control shell 101, and the temperature control component includes an adjustment ring 103 rotatably arranged on the top surface of the base 1, the bottom end of the adjustment ring 103 extends to the bottom surface of the base 1, a ring gear 104 is fixed to the bottom end of the adjustment ring 103, a plurality of adjustment grooves 105 are opened on the top surface of the adjustment ring 103, an adjustment block 106 is slidably arranged inside the adjustment groove 105, a heating rod 107 is fixed to the top surface of the adjustment block 106, and the heating rod 107 is the prior art.

[0023] In the embodiment, an extension plate 108 is fixed to the outer wall of the base 1, and a first motor 109 is fixed to the top surface of the extension plate 108. The first motor 109 has a self-locking function. The output shaft of the first motor 109 passes through the top surface of the extension plate 108 and extends to the bottom surface of the extension plate 108. The output shaft of the first motor 109 is rotatably arranged with the penetration point of the extension plate 108. The output shaft of the first motor 109 is fixed with a driving gear 110, and the driving gear 110 is meshed with the ring gear 104. Through the setting and use of the adjustment ring 103 and the adjustment groove 105, the adjustment ring 103 will drive the heating rod 107 to approach or move away from the melting box 2 when rotating, thereby effectively preventing the residual heat of the heating rod 107 from heating the plastic and causing excessive melting. In addition, the sealing cover 102 does not need to be opened when performing heat insulation, which effectively prevents the molten plastic from contacting with the air, which may quickly cool down or be contaminated by air dust.

[0024] In the embodiment, a plurality of limit frames 111 are fixed inside the temperature control housing 101, and a limit strip 114 is fixed on the outer wall of the heating rod 107. The limit strip 114 and the limit frame 111 are slidably arranged inside to limit the heating rod 107.

[0025] In the embodiment, a plurality of heat insulation plates 112 are fixed to the top surface of the adjustment ring 103. The heat insulation plates 112 are of prior art. The heat insulation plates 112 are parallel to the adjacent adjustment grooves 105. The heat insulation plates 112 fit tightly against the outer wall of the heating rod 107 to better insulate the heat of the heating rod 107.

[0026] In the embodiment, a second motor 201 is fixed to the inner bottom surface of the melting box 2, and the output shaft of the second motor 201 passes through the bottom surface of the melting box 2 and extends to the inside of the melting box 2. An oil seal is provided at the penetration point between the output shaft of the second motor 201 and the melting box 2, and a stirring blade 202 is fixed to the output shaft of the second motor 201. A controller and a temperature sensor are respectively fixed to the top surface of the sealing cover 102. The controller is a PLC controller, and the temperature sensor is the prior art. The detection end of the temperature sensor passes through the top surface of the sealing cover 102 and extends to the inside of the melting box 2. The detection end of the temperature sensor and the penetration point of the sealing cover 102 are treated with sealant. The temperature sensor, the first motor 109, the heating rod 107 and the second motor 201 are all electrically connected to the controller, which is used to mix the plastic during heating, so that the plastic is heated more evenly, and the melting temperature of the plastic can be detected in real time.

[0027] In the embodiment, two rotating handles 113 are fixed to the top surface of the sealing cover 102 near the front and rear sides. The two rotating handles 113 are mirror-symmetrical and are used to facilitate the staff to open the sealing cover 102.

[0028] Working principle: In use, the plastic to be melted is first placed into the melting box 2, and then the sealing cover 102 is threadedly connected to the melting box 2. At this time, the heating rod 107 is started by the controller to heat the melting box 2, and then the second motor 201 is started by the controller to drive the stirring blade 202 to stir the plastic, so that the plastic is heated more evenly. When the temperature sensor detects that the plastic cup is heated to a certain temperature, the controller starts the first motor 109 to drive the driving gear 110 to rotate. Under the meshing action of the ring gear 104 and the driving gear 110, the ring gear 104 will drive the adjusting ring 103 to rotate together. At this time, due to the limitation of the limiting frame 111 on the limiting bar 114 and the heating rod 107, when the adjusting ring 103 rotates, the adjusting block 106 will slide relatively inside the adjusting groove 105, and drive the heating rod 107 away from the melting box 2 under the inclined groove structure of the adjusting groove 105. At this time, the heat insulation plate 112 rotates to one side of the heating rod 107 with the adjusting ring 103 to effectively insulate the heating rod 107.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
