[0028] When the extrusion device 1 is used, the raw materials need to be added to the feeding hopper 102 at the top of the extrusion device 1, since the feeding pipe 2 and the charging hopper 201 are installed at the outer end of the extrusion device 1 and the feeding hopper 102, the charging hopper 201 is at a low position, the raw materials can be directly poured into the charging hopper 201 and placed, the charging hopper 201, the feeding pipe 2 and the discharge hopper 204 are in communication, at this time, the servo motor 203 is started to drive the feeding auger to rotate, so that the blades of the feeding auger can rotate, that is, the raw materials in the charging hopper 201 contact and rub with the blades of the feeding auger, the raw materials are gradually pushed to the discharge hopper 204 end direction for conveying, at the same time, there is also a slight tumbling, which is helpful for uniform distribution and prevention of blockage, that is, the raw materials are conveyed to the top of the feeding pipe 2 and discharged from the discharge hopper 204 to the feeding hopper 102, so that the feeding work can be quickly completed, without the need for manual carrying of the raw materials to the extrusion device 1, saving carrying time, achieving the purpose of saving time and effort, and improving the production efficiency of the cable insulation layer.

[0030] After the raw materials are fed into the feeding hopper 102, the feeding hopper 102 is in communication with the extrusion device 1, and the raw materials fall into the extrusion device 1. At this time, the three-phase alternating current asynchronous motor 104 is started to work, and the three-phase alternating current asynchronous motor 104 drives the motor shaft 105 and the large pulley 106 to rotate. Since the large pulley 106 and the small pulley a 108 are connected by the belt a 109, when the large pulley 106 rotates, the small pulley a 108 will be driven to rotate by the belt a 109, and the rotating shaft 107 and the feeding auger will be driven to rotate. The raw materials will be in contact with the blades of the feeding auger, and the raw materials will be transported into the extrusion pipe 101 by the feeding auger.

[0031] The extrusion device 1 is provided with a machine box 103 on one side of the outer end, a three-phase alternating current asynchronous motor 104 is installed in the machine box 103, a motor shaft 105 is installed at the output end of the three-phase alternating current asynchronous motor 104, a large pulley 106 is installed on the motor shaft 105, a rotating shaft 107 is rotatably connected to the outer end of the extrusion device 1 through a bearing, a feeding auger is installed in the extrusion device 1 and the extrusion pipe 101 and connected to the rotating shaft 107, a small pulley a 108 is installed at the outer end of the rotating shaft 107, and a belt a 109 is installed between the large pulley 106 and the small pulley a 108.

Under the driving action of the rotation and extrusion of the feeding auger, the molten state is extruded from the mold head 110 and forms a continuous and dense insulation layer, which can be collected and cooled.

[0034] After the raw materials are fed into the inside of the feeding hopper 102, the raw materials are in contact with the roller a3 and the roller b301 in the inside of the feeding hopper 102, and there are gap spaces between the roller a3, the roller b301 and the inner wall of the feeding hopper 102, and there are gap spaces between the roller a3 and the roller b301, so as to ensure that the raw materials can normally fall into the extrusion equipment 1. When the raw materials are accumulated in the inside of the feeding hopper 102 during the discharging process, the raw materials have poor flowability. When the rotating shaft 107 rotates, the small pulley c305 rotates together, the small pulley c305 and the small pulley b304 are connected through the belt b306, so as to drive the transmission shaft a302 and the roller a3 to rotate and roll, and the transmission gear 307 at the outer end of the transmission shaft a302 is meshed with the transmission gear 308 at the outer end of the transmission shaft b303, so as to drive the transmission shaft b303 and the roller b301 to rotate and roll together.

[0035] Wherein, the outer end of the feeding hopper 102 is provided with a rotating hole 309, the rotating hole 309 is provided with a sealing bearing 310, the two ends of the transmission shaft a302 and the transmission shaft b303 are rotatably connected with the sealing bearing 310, the two ends of the transmission shaft a302 and the transmission shaft b303 are connected with the rotating hole 309 at the outer end of the feeding hopper 102, and the transmission shaft a302 and the transmission shaft b303 are rotatably connected with the rotating hole 309 through the sealing bearing 310. The transmission shaft a302 and the transmission shaft b303 can be used to install the roller a3 and the roller b301 in the inside of the feeding hopper 102.

[0036] Working principle:

[0037] When the extrusion device 1 is in use, the raw materials need to be added into the feeding hopper 102 at the top of the extrusion device 1. Since the feeding pipe 2 and the charging hopper 201 are installed at the outer end of the extrusion device 1 and the feeding hopper 102, the charging hopper 201 is at a low position and the raw materials can be directly poured into the charging hopper 201 for placement. The charging hopper 201, the feeding pipe 2 and the discharging hopper 204 are in communication. At this time, the servo motor 203 is started to drive the feeding auger to rotate, so that the blades of the feeding auger can rotate. That is, the raw materials in the charging hopper 201 come into contact with the blades of the feeding auger in the feeding pipe 2 and are rubbed, and the raw materials are gradually pushed to the end of the discharging hopper 204 for conveying. At the same time, the raw materials are slightly tumbled, which helps to uniformly distribute and prevent clogging. That is, the raw materials are conveyed to the top of the feeding pipe 2 and discharged from the discharging hopper 204 to the feeding hopper 102, and then the feeding work can be quickly completed.

[0038] After the raw materials are fed into the feeding hopper 102, the feeding hopper 102 and the extrusion device 1 are in communication, and the raw materials fall into the extrusion device 1. At this time, the three-phase asynchronous motor 104 is started to work, and the three-phase asynchronous motor 104 drives the motor shaft 105 and the large pulley 106 to rotate. Since the large pulley 106 and the small pulley a 108 are connected by the belt a 109, when the large pulley 106 rotates, the small pulley a 108 is driven to rotate by the belt a 109, and then the rotating shaft 107 and the feeding auger are driven to rotate. The raw materials come into contact with the blades of the feeding auger, and the raw materials are conveyed into the extrusion pipe 101 by the feeding auger. The heating block works to heat the raw materials from a solid state to a molten state. Under the rotation and extrusion of the feeding auger, the raw materials are extruded from the mold head 110 and form a continuous and dense insulation layer, and then the insulation layer can be collected and cooled.

[0039] When the raw materials are accumulated in the feeding hopper 102 during the discharging process, the raw materials have poor flowability. Since the rotating shaft 107 rotates to drive the small pulley c 305 to rotate, the small pulley c 305 and the small pulley b 304 are connected by the belt b 306, and then the transmission shaft a 302 and the roller a 3 are driven to rotate and roll. The transmission shaft a 302 and the transmission shaft b 303 are connected by the transmission gear 307 and the transmission gear 308, and then the transmission shaft b 303 and the roller b 301 are driven to rotate and roll. The rotation and rolling of the roller a 3 and the roller b 301 in the raw materials push the raw materials, so that the raw materials have good flowability, the raw materials can smoothly fall, the possibility of material accumulation and clogging is reduced, and the problem of clogging between the feeding hopper 102 and the extrusion device 1 can be effectively solved.
