[0002] An extruder is a device used to plasticize and extrude materials into shapes. It is widely used in plastics processing, rubber processing and other fields. The extruder uses the pressure and shear force generated by the rotation of the screw to transport, compact, heat and melt the material, so that it is in a uniform plasticized state. Then, under the thrust of the screw, the material is extruded through the die and cooled. However, existing extruders have some shortcomings in use. In order to meet the needs of the market, a single-screw strip extruder is needed.
[0003] Existing extruders suffer from operational and maintenance inconveniences. Die assembly is difficult, hindering the user from fitting dies with different flow channels onto the extrusion tube surface, thus complicating operation. Furthermore, their guiding effect on the edge strips is inadequate, reducing cooling and forming efficiency and consequently lowering production efficiency. In addition, existing extruders typically lack water recycling capabilities, leading to water waste and diminishing their practicality. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are: the single screw strip extruder not only makes it easier for users to assemble dies with different flow channels on the surface of the extrusion tube, making the extruder easier to operate, but also allows the extruded strips to be cooled and formed better inside the cooling water tank, resulting in higher production efficiency of strips, and also reduces water waste, making the extruder more practical.
[0014] 1. With a convenient assembly mechanism, the user pushes the mold, causing the guide block to slide on the inner wall of the guide groove. Under the combined action of the guide block and the guide groove, the mold is guided. At this time, the guide block drives the positioning block to automatically lock onto the inner wall of the mold, positioning the mold in the installation position. Then, the user tightens the fastening screws on the surface of the mounting block.

[0015] 2. With the addition of a guiding mechanism, the user places the guide frame on the inner wall of the cooling water tank and the water tank respectively, and then tightens the mounting studs on the surface of the mounting plate. Under the action of the mounting studs, the guide frame is installed on the inner wall of the cooling water tank and the water tank respectively. When the extruded strip enters the interior of the water tank through the feed port, the strip drives the guide wheel to rotate on the inner wall of the guide frame. Under the action of the guide wheel, the strip can be guided, making the strip smoother during conveying and achieving a better cooling and forming effect inside the water tank and the cooling water tank. This realizes the function of the extruder guiding the strip, thus enabling the extruded strip to have a better cooling and forming effect inside the cooling water tank when the extruder is in use, and making the production efficiency of the strip higher when the extruder is in use.
[0016] 3. By incorporating a water circulation and recycling mechanism, the outflowing water flows into the water collection frame for centralized collection. A level sensor monitors the water level in the collection frame in real time. When the level sensor detects excessive water, it sends a signal to the controller. Upon receiving the signal, the controller automatically controls the water pump on the control panel. The pump draws water out of the collection frame through the suction pipe and returns it to the cooling water tank through the return pipe. This achieves the function of recycling the outflowing water from the extruder, reducing water waste and making the extruder more practical to use. Attached Figure Description

[0026] Furthermore, such as Figure 2 and Figure 4As shown, the surfaces of the mold 115 and the extrusion tube 120 are provided with a convenient assembly mechanism 2. The convenient assembly mechanism 2 consists of fastening pins 21, mounting blocks 22, guide blocks 23, positioning blocks 24 and guide grooves 25.

[0027] During implementation, the mold 115 is pushed so that the guide block 23 slides on the inner wall of the guide groove 25. Under the combined action of the guide block 23 and the guide groove 25, the mold 115 is guided. At this time, the guide block 23 drives the positioning block 24 to automatically lock onto the inner wall of the mold 115, positioning the installation position of the mold 115. Subsequently, the user tightens the fastening nails 21 on the surface of the mounting block 22. Under the action of the fastening nails 21, the mold 115 is installed on the surface of the extrusion tube 120, so as to realize the function of convenient assembly of the mold 115 in the extruder.
[0028] Furthermore, such as Figure 2 and Figure 5 As shown, the inner walls of the cooling water tank 106 and the water tank 122 are provided with a guide mechanism 3. The guide mechanism 3 consists of a guide wheel 31, a guide frame 32, a mounting stud 33, and a mounting plate 34. The inner walls of both the cooling water tank 106 and the water tank 122 are provided with a guide frame 32. The surface of the guide frame 32 is mounted with a mounting plate 34. The mounting plate 34 is connected to the inner wall of the water tank 122 and the inner wall of the cooling water tank 106 through the mounting stud 33. The inner wall of the guide frame 32 is provided with a guide wheel 31, and the guide wheel 31 and the inner wall of the guide frame 32 rotate and cooperate with each other.
[0029] In practice, the user places the guide frame 32 on the inner walls of the cooling water tank 106 and the water tank 122 respectively, and then tightens the mounting studs 33 on the surface of the mounting plate 34. Under the action of the mounting studs 33, the guide frame 32 is installed on the inner walls of the cooling water tank 106 and the water tank 122 respectively. When the extruded strip enters the interior of the water tank 122 through the feed port 121, the strip drives the guide wheel 31 to rotate on the inner wall of the guide frame 32. Under the action of the guide wheel 31, the strip can be guided, making the strip smoother during conveying and achieving a better cooling and forming effect inside the water tank 122 and the cooling water tank 106, so as to realize the function of the extruder guiding the strip.
[0030] Furthermore, such as Figure 2 and Figure 6As shown, a water circulation and recovery mechanism 4 is provided on the surface of the operating table 105. The water circulation and recovery mechanism 4 includes a water pump 41, a return pipe 42, a water collection frame 43, a liquid level sensor 44, and a suction pipe 45. The water collection frame 43 is installed on the surface of the operating table 105 and is fixed to the surface of the water tank 122. A liquid level sensor 44 is installed on the inner wall of the water collection frame 43. The liquid level sensor 44 can be a UT series model. The output terminal of the liquid level sensor 44 is connected to the controller 1. The input terminal of the controller 105 is electrically connected. A water pump 41, which can be an SLG series pump, is mounted on the surface of the control panel 105. The input terminal of the water pump 41 is electrically connected to the output terminal of the controller 11. A suction pipe 45 is installed at the output terminal of the water pump 41. One end of the suction pipe 45 passes through the control panel 105 and the water collection frame 43 and extends into the interior of the water collection frame 43. A return pipe 42 is installed at the output terminal of the water pump 41. One end of the return pipe 42 extends into the interior of the cooling water tank 106.
[0031] During implementation, the outflowing water flows into the water collection frame 43 for centralized collection. The water volume inside the water collection frame 43 is monitored in real time by the level sensor 44. When the level sensor 44 detects that there is too much water inside the water collection frame 43, the level sensor 44 sends a signal to the controller 11. After receiving the signal, the controller 11 automatically controls the water pump 41 on the surface of the operating table 105 to work. Under the action of the water pump 41, the water inside the water collection frame 43 is sucked out through the suction pipe 45, and then the water is returned to the cooling water tank 106 through the return pipe 42, so as to realize the function of the extruder to recycle the outflowing water.
[0032] Working principle: In use, first place the frame 1 in the designated position. The user places the mold 115, which conforms to the edge strip production specifications, on the surface of the extrusion tube 120, and then pushes the mold 115 so that the guide block 23 slides on the inner wall of the guide groove 25. Under the combined action of the guide block 23 and the guide groove 25, the mold 115 is guided. At this time, the guide block 23 drives the positioning block 24 to automatically lock onto the inner wall of the mold 115, positioning the installation position of the mold 115. Subsequently, the user tightens the fastening nails 21 on the surface of the mounting block 22. Under the action of the fastening nails 21, the mold 115 is installed on the surface of the extrusion tube 120, so as to realize the function of convenient assembly of the mold 115 of the extruder. This makes it convenient for the user to assemble the mold 115 of different flow channels on the surface of the extrusion tube 120 when using the extruder, making the extruder more convenient to operate.
[0033] Subsequently, the granular raw material is introduced into the feed cylinder 102 through the feed pipe 110. The granular raw material enters the feed box 112 through the feed cylinder 102. The controller 11 controls the drive motor 108 to work. Under the action of the drive motor 108, the drive gear 107 is driven to rotate. Under the meshing action of the drive gear 107 and the driven gear 109, the driven gear 109 is driven to rotate inside the drive box 101. When the driven gear 109 rotates, it drives the rotating rod 111 to rotate, thereby driving the conveying screw 114. The material rotates inside the housing 103, and the granular raw material entering the housing 103 is conveyed by the feeding screw 114. According to existing technology, the housing 103 is divided into a feeding section, a melting section, and a homogenization chamber. The feeding screw 114 continuously conveys the granular material inside the housing 103 from the feeding chamber to the melting section. Subsequently, the controller 11 controls the electric heater 104 to operate, generating high temperature to heat the granular material inside the housing 103, melting it into a viscous flow state. The pushing force of the feed screw 114, through its cooperation with the gap between the inner wall of the housing 103, transports the molten raw material to the homogenization section and continuously extrudes and plasticizes the molten material. Subsequently, raw materials of different colors inside the frame 1 are continuously and stably passed through the perforated plate 117 and the filter screen 118 into the extrusion tube 120, and then into the mold 115 to be extruded and shaped. Since the mold 115 has flow channels, the raw material and the flow channels in the mold 115 form a continuous body with the same shape. The extruded strip enters the water tank 122 and the cooling water tank 106 through the feed port 121 for cooling and shaping. Then, it is pulled out with the help of an external traction device to obtain the shaped strip. The temperature inside the housing 103 is monitored in real time by the temperature sensor 113, and the monitoring results are sent to the controller 11 to ensure that the raw material melts and plasticizes at a suitable temperature. The pressure sensor 119 can monitor the pressure of the raw material during extrusion. By observing the controller 11, the user can judge whether the extrusion process of the raw material inside the housing 103 is going smoothly.
[0034] Subsequently, the user places the guide frame 32 on the inner walls of the cooling water tank 106 and the water tank 122 respectively, and then tightens the mounting studs 33 on the surface of the mounting plate 34. Under the action of the mounting studs 33, the guide frame 32 is installed on the inner walls of the cooling water tank 106 and the water tank 122 respectively. When the extruded strip enters the interior of the water tank 122 through the feed port 121, the strip drives the guide wheel 31 to rotate on the inner wall of the guide frame 32. Under the action of the guide wheel 31, the strip can be guided, making the strip smoother during conveying and achieving a better cooling and forming effect inside the water tank 122 and the cooling water tank 106. This realizes the function of the extruder guiding the strip, so that the extruded strip can achieve a better cooling and forming effect inside the cooling water tank 106 when the extruder is used, and the production efficiency of the strip during the use of the extruder is higher.
[0035] Subsequently, when the worker introduces the extruded strip into the water tank 122 and cooling water tank 106 through the feed port 121, water will flow out of the water tank 122 and cooling water tank 106. The outflowing water flows into the water collection frame 43 for centralized collection. Under the action of the liquid level sensor 44, the water volume inside the water collection frame 43 is monitored in real time. When the liquid level sensor 44 detects that the water volume inside the water collection frame 43 is too high, the liquid level sensor 44 sends a signal to the controller 11. After receiving the signal, the controller 11 automatically controls the water pump 41 on the surface of the operating table 105 to work. Under the action of the water pump 41, the water inside the water collection frame 43 is sucked out through the water suction pipe 45, and then the water is returned to the cooling water tank 106 through the return pipe 42, so as to realize the function of extruder recycling the outflowing water, thereby making it less likely to cause water waste when using the extruder, making the extruder more practical when using it, and finally completing the use of the extruder and completing the short-term use.
