[0028] The following describes some embodiments of the utility model in conjunction with the accompanying drawings to provide a conical twin-screw granulator.

[0029] Embodiment 1:

[0030] Reference Figure 1-6 , which is the first embodiment of the utility model, provides a conical twin-screw granulator, including an extrusion component 100, a cooling box 200, a perforated plate 300, a salvaging component 400, a guide component 500, a pressure detection component 600, an air cooling component 700 and a shearing machine 800.

[0031] Specifically, the extrusion component 100 includes a base 101, a barrel 102 arranged on the top of the base 101, and an audible and visual alarm 106 arranged on the base 101. The extrusion component 100 also includes a driving motor 103 arranged at the top of the base 101, a reducer 104 arranged at the output end of the driving motor 103, and an upper hopper 105 arranged on the base 101. The reducer 104 is fixedly connected to the conical twin screw in the barrel 102. A certain amount of material can be poured into the upper hopper 105. After pouring, the driving motor 103 can be controlled to operate. The operation of the driving motor 103 can drive the conical twin screw to rotate through the reducer 104. The rotating conical twin screw will convey the material, and finally it is extruded through the extruder head.

[0032] Specifically, the cooling box 200 is arranged on the rear side of the base 101, and a slope 201 is provided at the bottom of the cooling box 200. The slope 201 has a guiding effect, which is convenient for guiding the moisture blown off by the wind. The inner bearing of the cooling box 200 is connected to a rotating rod 202, which is convenient for conveying strip materials.

[0033] Specifically, the orifice plate 300 is arranged on the inner side of the cooling box 200, and the cooling box 200 can be divided into two parts by the orifice plate 300. The smaller part can receive the material after the broken bars. Since the holes on the orifice plate 300 can flow cooling water, the cooling water can be transported to cool the broken bars.

[0034] Specifically, the salvage assembly 400 includes a grid 401 placed in the cooling box 200 and a handle 402 arranged on the top of the grid 401. The handle 402 can be grasped, and after being grasped, the grid 401 can be driven to move upward by the handle 402, so that the broken strip can be taken out and moved for use.

[0035] Specifically, the guide assembly 500 includes a guide roller 501 inserted into the cooling box 200, a first stud 502 arranged on both sides of the guide roller 501, and a first nut 503 threadedly connected to the first stud 502. The first nut 503 can be loosened, and after loosening, the guide roller 501 can be moved up and down, so that the height of the guide roller 501 can be adjusted. After adjustment, the strip material can be guided by the guide roller 501 for transportation.

[0036] Specifically, the pressure detection component 600 includes a fixed shaft 601 arranged on the cooling box 200, a pressure sensor 604 arranged in the fixed shaft 601 and a detection plate 605 arranged on the pressure sensor 604. The pressure detection component 600 also includes a second stud 602 arranged on both sides of the fixed shaft 601 and a second nut 603 threadedly connected to the second stud 602. The second nut 603 can be loosened. After loosening, the fixed shaft 601 can be moved up and down to adjust the height of the fixed shaft 601. After adjustment, the pressure sensor 604 can detect the pressure of several strip materials outside the detection plate 605. When any strip material is disconnected, the pressure sensor 604 will transmit this signal to the control terminal, and the control terminal can control the sound and light alarm 106 to make a sound for reminder.

[0037] Specifically, the air cooling assembly 700 includes an air hood 701 arranged on the top of the cooling box 200 and a connecting pipe 702 arranged on the top of the air hood 701. The connecting pipe 702 is fixedly connected to the fan, and the fan can transport wind through the air hood 701 to the strip material on the rotating roller 202 to cool and dry the strip material.

[0038] Specifically, the shearing machine 800 is arranged at the rear side of the cooling box 200, and the shearing machine 800 can shear the strip material for granulation.

[0039] It should be noted that the driving motor 103, the sound and light alarm 106 and the pressure sensor 604 are all electrically connected to the control terminal.

[0040] The working principle and use process of the utility model are as follows: when in use, the cooling box 200 can be divided into two parts by the orifice plate 300, and the smaller part can receive the strip material after the strip is broken. Since the holes on the orifice plate 300 can flow cooling water, the cooling water can be transported to cool the broken strip. After cooling, the handle 402 of the salvage component 400 can be held, and after holding it tightly, the grid 401 can be driven to move upward through the handle 402, so that the broken strip can be taken out and moved for use. During use, the pressure sensor 604 can detect the pressure of several strip materials outside the detection plate 605. When any strip material is broken, the pressure sensor 604 will transmit this signal to the control terminal, and the control terminal can control the sound and light alarm 106 to make a sound for reminder. Finally, the connecting pipe 702 can be connected to the fan. After connection, the fan can transport wind through the wind cover 701 to the strip material on the rotating rod 202, so as to cool and dry the strip material. The blown away water can fall into the inclined surface 201 due to the effect of gravity for reflux.
