Description

Technical Field

[0001] This utility model relates to a punching die, specifically an extrusion molding device for preparing modified fiber core rod media, belonging to the field of modified fiber core rod media preparation technology. Background Technology

[0002] In the production of modified fiber core rods, extrusion equipment is generally required for processing. The raw materials are usually stirred and mixed, and then the screw inside the extrusion molding equipment rotates to push the melt forward, establish stable pressure, and then extrude it through a die for processing.

[0003] When the mixed raw materials are put into the feeding hopper, since there is no stirring and heat preservation equipment in the feeding hopper, the raw materials are prone to cooling and solidification due to ambient temperature or heat dissipation from the equipment during the feeding stage, which affects the production quality of modified fiber core rods. Utility Model Content

The device can stir the raw materials in the hopper through the stirring rod and deliver hot air to the channel through the air inlet, thereby heating the raw materials in the hopper. This prevents the raw materials from cooling and solidifying in the hopper, which would affect the extrusion quality of the modified fiber core rod.

[0024] As a technical optimization of this utility model, multiple rotating rods 203 are arranged in a ring array, and multiple stirring rods 204 are arranged in a ring array and a linear distribution on the rotating rods 203 respectively. The stirring rods 204 and the through grooves 206 in the rotating rods 203 are connected through each other. The stirring rods 204 fixed on two adjacent rotating rods 203 are staggered, so as to better stir the raw materials in the hopper 202.

[0025] As a technical optimization of this utility model, a fixed frame 210 is fixedly connected to the left side of the feeding hopper 202, and a connecting pipe 211 is fixedly connected to the right side of the fixed frame 210. The connecting pipe 211 and the rotating rod 203 are rotatably connected, and hot air is transported to the through slot 206 through the air inlet 205, thereby heating the raw materials in the feeding hopper 202.

[0026] As a technical optimization of this utility model, a limiting ring 212 is fixedly connected to the left side of the rotating rod 203. The limiting ring 212 and the connecting pipe 211 are rotatably connected. The limiting ring 212 can limit the connection pipe 211 and the rotating rod 203.

[0027] As a technical optimization of this utility model, an extrusion structure 3 is installed on the conveying cylinder 201. The extrusion structure 3 includes a spiral conveying rod 301. The spiral conveying rod 301 is rotatably connected inside the conveying cylinder 201. A constriction plate 302 is fixedly connected to the left side of the conveying cylinder 201. The constriction plate 302 has an overall trumpet-shaped structure. The raw material is conveyed into the constriction plate 302 through the spiral conveying rod 301. The melt pressure is increased by decreasing the cross-sectional area to ensure the material density and eliminate air bubbles.

[0028] As a technical optimization of this utility model, an extrusion tube 303 is fixedly connected to the left side of the constriction plate 302, and a base 304 is fixedly connected to the bottom end of the extrusion tube 303. A baffle 305 is rotatably connected to the base 304. By rotating the baffle 305 on the base 304, the outlet of the extrusion tube 303 can be protected.

[0029] As a technical optimization of this utility model, a locking block 306 is fixedly connected to the baffle 305. The locking block 306 is made of rubber plastic material. The locking block 306 can limit the position of the baffle 305 and also seal the outlet of the extrusion tube 303.

[0030] As a technical optimization of this utility model, a transmission structure 4 is installed on the frame 1. The transmission structure 4 includes a motor 401. The motor 401 is installed at the bottom of the frame 1. A first pulley 402 is fixedly connected to the output end of the motor 401. A second pulley 403 is fixedly connected to the right side of the spiral conveying rod 301. The first pulley 402 and the second pulley 403 are driven by a belt 404. When the motor 401 is started, the spiral conveying rod 301 is driven to rotate through the transmission of the first pulley 402, the second pulley 403 and the first belt 404.

[0031] As a technical optimization of this utility model, a third pulley 405 is fixedly connected to both the rotating shaft 208 and the spiral conveying rod 301. The two third pulleys 405 are driven by a second belt 406. The rotation of the spiral conveying rod 301 can drive the rotating shaft 208 to rotate through the transmission of the third pulleys 405 and the third belt 406.

[0032] In use, when manufacturing modified fiber core rods, the mixed raw materials are introduced into the feeding hopper 202. The air inlet of the fixing frame 210 is then connected to an external heating device. The motor 401 is then started, driving the screw conveyor 301 to rotate via the first pulley 402, the second pulley 403, and the first belt 404. This, in turn, drives the rotating shaft 208 to rotate via the third pulley 405 and the third belt 406. Consequently, the first gear 207 and the second gear 209 drive multiple rotating rods 203 to rotate simultaneously. This allows the stirring rod 204 to stir the raw materials in the feeding hopper 202. Simultaneously, hot air is delivered to the through-slot 206 through the air inlet 205, thus stimulating the raw materials in the feeding hopper 202. The raw materials in hopper 202 are heated to prevent them from cooling and solidifying in the hopper 202, which would affect the extrusion quality of the modified fiber core rod. The limiting ring 212 can limit the connecting pipe 211 and the rotating rod 203. After the raw materials flow into the conveying cylinder 201 through the hopper 202, they are conveyed to the constriction plate 302 by the spiral conveying rod 301. The decrease in cross-sectional area increases the melt pressure to ensure the material is dense and eliminates air bubbles. Therefore, the modified fiber core rod can be extruded through the extrusion pipe 303. The baffle 305 on the rotating base 304 can protect the outlet of the extrusion pipe 303. The clamping block 306 can limit the baffle 305 and seal the outlet of the extrusion pipe 303.
