Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a cooling structure for a straw extruder. Background Technology

[0002] A straw extruder is a type of plastic processing machinery specifically designed for producing plastic straws. The straw extruder heats plastic granules or other plastic materials to a molten state, then uses the rotation of a screw to extrude them through a die, and finally cools and solidifies them to form straws of a specific shape and size.

[0003] Existing straw extruders generally use water cooling to cool the straws. While water cooling can indeed cool the straws, in actual use, the temperature of the formed straws is too high, and water cooling alone may affect the cooling effect. Therefore, a cooling structure for straw extruders is proposed to improve the above-mentioned problem. Utility Model Content

[0004] The purpose of this invention is to provide a cooling structure for a straw extruder. After the straw has undergone a round of water cooling in the cooling box, the first rotating shaft is driven by an external motor. This causes the first rotating shaft to engage the drive gear and the first driven gear, which in turn engages the second driven gear, causing all three fan blades to rotate simultaneously and air-cool the straw. By combining water cooling and air cooling, a dual cooling effect is achieved. This solves the problem that existing straw extruders generally use water cooling to cool the straw. While water cooling can indeed cool the straw, in actual use, the temperature of the formed straw is too high, and relying solely on water cooling may affect the cooling effect.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a cooling structure for a straw extruder, comprising a working platform, an air-cooling component, a water-cooling component, an extrusion component, and a conveying component. The air-cooling component includes a support plate with a first circular groove and two second circular grooves. A first rotating shaft is fitted onto the first circular groove, and a drive gear is mounted on the first rotating shaft. A bearing is embedded in the second circular groove, and a second rotating shaft is fitted inside the bearing. A first driven gear is mounted on one of the second rotating shafts, and a second driven gear is mounted on the other second rotating shaft. The drive gear meshes with the first driven gear, and the first driven gear meshes with the second driven gear. Fan blades are mounted on the drive gear, the first driven gear, and the second driven gear. A first motor is connected to the end of the first rotating shaft away from the drive gear.

[0007] Furthermore, the water-cooling assembly includes a cooling box with a first through hole and a second through hole. A water pump is installed inside the cooling box, with an inlet pipe installed at the inlet end of the water pump and connected to the side wall of the cooling box. An outlet pipe is installed at the outlet end of the water pump and connected to the side wall of the cooling box.

[0008] Furthermore, the cooling box is mounted on the work platform, and the support plate is mounted on the cooling box.

[0009] Furthermore, the extrusion assembly includes a cylindrical tube and a cylindrical rod. A screw is installed at one end of the cylindrical rod, and the screw rotates with the inner cavity of the cylindrical tube. A feed hopper is installed on the cylindrical tube. An extrusion head is installed at the end of the cylindrical tube away from the cylindrical rod. The extrusion head is located in the cooling box through a first through hole. A second motor is connected to the other end of the cylindrical rod.

[0010] Furthermore, the conveying assembly includes a support base, which is mounted on the work platform. There are three support bases, which are on the same horizontal plane. Two third circular grooves are opened on the support bases. The two ends of the transmission roller are respectively fitted into the two third circular grooves. A cylinder is connected to the central shaft of one of the transmission rollers, and a third motor is connected to the end of the cylinder away from the transmission roller.

[0011] Furthermore, an arc-shaped frame is installed on the work platform. There are two arc-shaped frames, which are on the same horizontal plane and cooperate with the round tube.

[0012] This utility model has the following beneficial effects:

[0013] This invention incorporates a water-cooling component and an air-cooling component in the cooling structure of a straw extruder. After the straw undergoes a round of water cooling in the cooling box, an external motor drives the first rotating shaft to move, causing the first rotating shaft to engage the drive gear and the first driven gear. The first driven gear then engages the second driven gear, causing all three fan blades to rotate simultaneously, thus providing air cooling for the straw. This combination of water cooling and air cooling achieves a dual cooling effect, solving the problem that existing straw extruders generally use water cooling to cool the straw. While water cooling does indeed cool the straw, in actual use, the high temperature of the formed straw means that relying solely on water cooling may affect the cooling effect.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A screw 403 is installed at one end of the cylindrical rod 402. With the screw 403 rotating in conjunction with the inner cavity of the cylindrical tube 401, the cylindrical rod 402 drives the screw 403 to rotate inside the cylindrical tube 401, thereby plasticizing the material. With an extrusion head 405 installed at the end of the cylindrical tube 401 away from the cylindrical rod 402, the extrusion head 405 extrudes the plasticized material to form a straw.

[0026] The water-cooling assembly 3 includes a cooling box 301, which is installed on the working platform 1. A first through hole 302 is provided in the cooling box 301.

A water outlet pipe 306 is installed at the water outlet end of the water pump 304. With the water outlet pipe 306 connected to the side wall of the cooling box 301, the water pump 304 controls the water outlet pipe 306 to discharge coolant, so that the coolant in the cooling box 301 can maintain a suitable temperature, thereby effectively water-cooling the suction tube.

[0027] The conveying assembly 5 includes a support base 501, which is mounted on the working platform 1. There are three support bases 501, which are on the same horizontal plane. Two third circular grooves 502 are provided on the support base 501. The two ends of the transmission roller 503 are respectively fitted on the two third circular grooves 502.

With a third motor connected to the end of the cylinder 504 away from the transmission roller 503, the cylinder 504 is driven to rotate by the external third motor. With the cylinder 504 connected to the central axis of one of the transmission rollers 503, the cylinder 504 drives the transmission roller 503 to rotate, thereby achieving the effect of conveying the suction tube and placing the suction tube directly below the air-cooling assembly 2.

[0029] The air-cooled assembly 2 includes a support plate 201, which is mounted on the cooling box 301. The support plate 201 has a first circular groove 202 and two second circular grooves 203.

[0030] When air cooling of the straw is required, with a first motor connected to the end of the first rotating shaft 204 away from the driving gear 205, the first rotating shaft 204 is driven to rotate by the external first motor. With the driving gear 205 installed on the first rotating shaft 204, the first rotating shaft 204 drives the driving gear 205 to rotate. With the driving gear 205 meshing with the first driven gear 208 and the first driven gear 208 meshing with the second driven gear 209, the driving gear 205 drives the first driven gear 208 to rotate, and the first driven gear 208 drives the second driven gear 209 to rotate. With fan blades 210 installed on the driving gear 205, the first driven gear 208, and the second driven gear 209, the fan blades rotate simultaneously, thereby achieving the effect of air cooling of the straw.
