[0030] A method for using a detection device for modified resin production, the steps are as follows:

[0031] Step 1: Cover the upper cover body on the mounting flange and fix it with bolts, then install the lower cover body on the conveying pipe and fix it with bolts on the mounting flange, connect the air inlet with the output end of the external hot air generating device, and connect the return port with the external hot air recovery device to complete the installation of the device;

[0032] Step 2: The hot air enters the air inlet duct through the air inlet, and then enters the right cavity 2 through the air inlet duct, and is guided by the air guide plate, so that the hot air blows and drives the axial flow fan blades and the rotating shaft on the right to rotate, and the rotating shaft on the right drives the upper gear to rotate, and similarly, the rotating shaft and the upper gear on the left can be driven to rotate, and finally the hot air is output from the return port to the external heat recovery device, completing the hot air circulation and the rotation of the upper gear.

Then install the lower cover body on the conveying pipe and fix it by bolts on the mounting flange. Connect the air inlet to the output end of the external hot air generating device, and connect the return port to the external hot air recovery device to complete the installation of the device. The hot air enters the air inlet pipe through the air inlet, and then enters the second cavity on the right side through the air inlet pipe, and is guided by the air guide plate, so that the hot air blows and drives the axial flow fan blades and the rotating shaft on the right side to rotate, and the rotating shaft on the right side rotates.

Finally, the hot air is input into the return pipe from the left connecting pipe, and then output to the external hot air recovery device through the return port, completing the hot air circulation and the rotation of the upper gear. The lower cover body and the upper cover body are made of heat-conducting materials, which is convenient for heating and heat preservation of the lower cover body and the upper cover body as a whole, solving the problem that the resin part is not well insulated and it is not convenient for the detection and use of liquid resin.

[0037] 2. An auxiliary mechanism is provided. When the upper gear rotates, the outer gear ring is driven to rotate at the same time. The top groove is used to make way for the upper gear. Since the inner side of the outer gear ring is provided with an internal thread and the outer side of the inner cylinder is provided with an external bidirectional thread, the movement of the inner cylinder drives the slider to slide inside the slide groove. The slider compresses the auxiliary spring, and the slider plays a limiting role, so that when the outer gear ring rotates, it can drive the inner cylinder to move left and right. The limit retaining ring is used to limit the movement of the inner cylinder, and the reciprocating movement of the inner cylinder drives the conical cylinder to move back and forth, and the conical cylinder drives the internal cross block to move. When the liquid resin is subsequently transported to the position of the lower cover by the conveying pipeline, the reciprocating movement of the cross block disturbs the liquid resin, making the liquid resin more uniform and improving the transparency detection effect. Then the liquid resin is transported to the inside of the colorimetric tube through the inner cylinder, and the laser generator and the detector are started. The laser generator emits light to irradiate the colorimetric tube vertically. The detector receives the transmitted light and feeds it back to the external display device. The operator can observe and judge, which solves the problem that the liquid resin may be locally uneven, affecting the accuracy of the detection result. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] An auxiliary mechanism 7 is arranged inside the lower cover body 1, and the auxiliary mechanism 7 includes a symmetrically arranged mounting cylinder 71 and an outer gear ring 72. The two mounting cylinders 71 are located at both ends of the colorimetric tube 8. The outer gear ring 72 is rotatably connected to the mounting cylinder 71, and the outer gear ring 72 is meshingly connected to the upper gear 68. The interior of the mounting cylinder 71 is slidably connected to an inner cylinder body 73, and a conical cylinder 74 is fixedly connected to one side of the inner cylinder body 73.

[0063] The internal thread and the external bidirectional thread are adaptably connected, the conical tube 74 is slidably connected to the mounting tube 71, and the conical tube 74 is located on the side of the inner cylinder 73 away from the colorimetric tube 8. The internal thread and the external bidirectional thread are adaptably connected, the conical tube 74 is slidably connected to the mounting tube 71, and the conical tube 74 is located on the side of the inner cylinder 73 away from the colorimetric tube 8.

The hot air enters the air inlet pipe 610 through the air inlet pipe 610, and then enters the right cavity 2 62 through the air inlet pipe 610, and is guided by the air guide plate 67, so that the hot air blows and drives the axial flow fan blades 66 and the rotating shaft 65 on the right to rotate, and the rotating shaft 65 on the right drives the upper gear 68 to rotate. Similarly, it can drive the rotating shaft 65 and the upper gear 68 on the left to rotate, and finally the hot air is output from the return port 614 to the external hot air recovery device, completing the hot air circulation and the rotation of the upper gear 68.

[0070] The rotation of the upper gear 68 also drives the outer gear ring 72 to rotate. The movement of the inner cylinder 73 drives the slider 77 to slide inside the slide groove 75, so that the inner cylinder 73 moves left and right. The reciprocating movement of the inner cylinder 73 causes the cross block 79 to move. The reciprocating movement of the cross block 79 disturbs the liquid resin, making the liquid resin more uniform. Then the liquid resin is transported to the inside of the colorimetric tube 8 through the inner cylinder 73, and the laser generator 9 and the detector 10 are started.

9. A method for using a detection device for modified resin production, characterized in that: The modified resin production detection device as claimed in claim 8 is used in the following steps: Step 1: Cover the upper cover (3) on the mounting flange (2) and fix it with bolts, then install the lower cover (1) on the conveying pipe (4) and fix it with bolts on the mounting flange (2), connect the air inlet (611) to the output end of the external hot air generating device, and connect the return port (614) to the external hot air recovery device, and complete the installation of the device; Step 2: The hot air enters the air inlet pipe (610) through the air inlet port (611), and then enters the right cavity (62) through the air inlet pipe (610), and is guided by the air guide plate (67), so that the hot air drives the right axial flow fan blade (66) and the rotating shaft (65) to rotate, and the right rotating shaft (65) then drives the upper gear (68) to rotate, and similarly drives the left rotating shaft (65) and the upper gear (68) to rotate, and finally the hot air is output from the return port (614) to the external hot air recovery device, completing the hot air circulation and the rotation of the upper gear (68). The lower cover body (1) and the upper cover body (3) are made of heat-conducting materials, which is convenient for heating and heat preservation of the lower cover body (1) and the upper cover body (3) as a whole; Step 3: The rotation of the upper gear (68) drives the outer gear ring (72) to rotate at the same time, and the movement of the inner cylinder (73) drives the slider (77) to slide inside the slide groove (75). The slider (77) plays a limiting role, thereby realizing the left and right movement of the inner cylinder (73), and the reciprocating movement of the inner cylinder (73) causes the cross block (79) to move. When the liquid resin is subsequently transported to the position of the lower cover (1) by the conveying pipe (4), the reciprocating movement of the cross block (79) disturbs the liquid resin, making the liquid resin more uniform, thereby improving the transparency detection effect; Step 4: The liquid resin is then transported to the interior of the colorimetric tube (8) through the inner cylinder (73), and the laser generator (9) and the detector (10) are started. The laser generator (9) emits light to vertically illuminate the colorimetric tube (8), and the detector (10) receives the transmitted light and feeds it back to an external display device, and the operator can observe and judge.
