Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a cooling and shaping device for an extruder. Background Technology

[0002] An extruder is an industrial device that uses mechanical force and heat to melt and continuously extrude polymer materials such as plastics, rubber, and polymer composites. When extruding products, the products need to be cooled and shaped to fix their shape for easier processing or transportation in the next step.

[0003] Currently, when using the cooling and shaping devices equipped on extruders, water cooling is more effective and gentler than air cooling for tubular cooling and shaping of composite materials. It can also wash away some of the burrs and waste generated during cutting. However, it usually only cools the outside of the tube and rarely cools the inside of the tube. This can easily cause uneven heating inside and outside the tube, resulting in cracks and reducing stability and yield. Utility Model Content

[0004] The purpose of this invention is to provide a cooling and shaping device for an extruder to solve the problems mentioned in the background art regarding tubular cooling and shaping of composite materials. Water cooling is more effective and gentler than air cooling and can wash away some of the burrs and waste generated during cutting. However, generally only the outside of the tube is cooled, and the inside of the tube is rarely cooled. This can easily lead to uneven heating inside and outside the tube, causing cracks and reducing stability and yield.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cooling and shaping device for an extruder, comprising a main body, a water cooling component on one side of the main body, the water cooling component comprising an inclined bar, a nozzle, an extension frame, a pneumatic cylinder, a hydraulic rod, and a conical nozzle, and a recycling component on one side of the main body, the recycling component comprising a water tank, a second water pump, a second connecting block, and a screen.

[0006] Both inclined strips are fixedly connected to the inner wall of opposite sides of the main body. Several nozzles are fixedly connected to the other side of the inclined strips. An extension frame is fixedly connected to one side of the main body. A pneumatic cylinder is fixedly connected to the top of the extension frame. A hydraulic rod is fixedly connected to the transmission end of the pneumatic cylinder. A connecting block is fixedly connected to the other end of the hydraulic rod. A flexible hose is fixedly connected to the top of the connecting block. The other end of the flexible hose passes through the extension frame and is fixedly connected to a water pump. A conical nozzle is fixedly connected to one side of the connecting block. This type of extruder is equipped with a cooling and shaping device that uses water cooling... The component consists of several nozzles located on inclined strips on the inner walls of both sides of the main body. The nozzles are positioned on the inclined surfaces of the strips to spray and cool the outer surface of the pipe. Increasing the spray angle improves cooling efficiency. A pneumatic cylinder drives a hydraulic rod to extend and retract, thereby extending the connecting block and the conical nozzle into the pipe. The flexible hose is extensible and can move and deform accordingly. The conical nozzle has a ring of nozzles that spray cooling in a circular manner. Water is supplied by a water pump to cool the inside of the pipe simultaneously. After spraying for a period of time, the conical nozzle retracts without obstructing the movement of the pipe, reducing the possibility of pipe cracking due to uneven heating inside and outside, and improving stability and yield.

[0007] Further preferably, the recycling component also includes a water-guiding slope, which is fixedly connected to the bottom inner wall of the main body. A water tank is opened on the bottom inner wall of the extension frame, and two water pumps are movably connected to the bottom inner wall of the water tank. This cooling and shaping device equipped with an extruder, by adding the recycling component, guides the water sprayed inside the main body to the water tank through the water-guiding slope. Water pumps 2 and 1 spray water outward from the water tank. Water pump 2 supplies water to the nozzle through a connecting pipe and a connecting block 2. The screen is inclined. When the pipe moves above the screen, the arc-shaped strip obstructs the liquid outflow device. The residual liquid is recycled back into the water tank through the screen, improving energy efficiency.

[0010] Further preferably, the main body is internally provided with a transmission component, which includes a rotary motor fixedly connected to the top of the main body. The transmission end of the rotary motor is fixedly connected to a synchronous shaft, which is movably connected to the main body. A drive roller is fixedly connected to the side surface of the synchronous shaft. This cooling and shaping device for the extruder, by adding the transmission component, allows the rotary motor to drive the synchronous shaft and the drive roller to rotate. The drive roller drives the driven roller and the synchronous shaft to move at the same speed and in the same direction via a synchronous belt, providing power for the movement of the pipe. The auxiliary wheel follows the movement to reduce friction.

[0011] More preferably, a synchronous belt is movably connected to the side surface of the first synchronous shaft, a second synchronous shaft is movably connected to the inner wall of one side of the synchronous belt and is movably connected to the main body, a driven roller is fixedly connected to the side surface of the second synchronous shaft, and several auxiliary wheels are movably connected to the inner wall of one side of the main body.

[0012] More preferably, each of the four bottom corners of the main body is fixedly connected to a support rod, and the bottom end of the support rod is fixedly connected to an anti-slip pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, the cooling and shaping device equipped with the extruder incorporates a water-cooling component. Several nozzles are located on the inclined strips on the inner walls of both sides of the main body, and the nozzles are positioned on the inclined surfaces of the strips to spray cooling onto the outer surface of the pipe. Increasing the spray angle improves cooling efficiency. A pneumatic cylinder drives a hydraulic rod to extend and retract, thereby extending the connecting block and the conical nozzle into the pipe. The flexible hose is extensible and can move and deform accordingly. The conical nozzle has a ring of nozzles that spray cooling around the pipe. Water is supplied by a water pump to cool the inside of the pipe simultaneously. After spraying for a period of time, the conical nozzle retracts, not obstructing the movement of the pipe, reducing the possibility of pipe cracking due to uneven heating inside and outside, and improving stability and yield.

[0015] In this invention, the cooling and shaping device equipped with the extruder incorporates a recovery component. The water sprayed inside the main body is guided by a water inlet slope to a water tank. Inside the water tank, water pumps 1 and 2 spray water outwards. Water pump 2 supplies water to the nozzles through a connecting pipe and a connecting block 2. The screen is inclined, and when the pipe moves above the screen, the arc-shaped strips obstruct the liquid outflow device. Residual liquid is recovered into the water tank through the screen, thus improving energy efficiency. Attached Figure Description
