Description

Technical Field

[0001] This application relates to the field of extruder auxiliary equipment technology, and in particular to an extruder storage bin with pretreatment function. Background Technology

[0002] An extruder is used to extrude material from a multi-hole die head or metal mesh by adding water or a suitable liquid to raw material powder and continuously stirring it. It is widely used in the production of plastic products. The plastic granules produced by the extruder must first be stored in a storage silo before further processing.

[0003] In existing technologies, extruder storage silos typically consist of a silo body, a feed inlet, a discharge outlet, and a simple mixing mechanism. The mixing mechanism often employs a single mixing shaft with mixing blades, with a motor directly driving the shaft to rotate, causing the raw materials inside the silo to flow slowly under gravity and achieve initial mixing. Some storage silos have a heating jacket installed outside the silo body to heat the raw materials inside through heat conduction, ensuring the materials meet basic temperature requirements before entering the extruder.

[0004] Regarding raw material heating, the existing external heating jacket structure used in storage silos suffers from low heat transfer efficiency, resulting in significant temperature differences in different areas of the raw materials within the silo and making it difficult to achieve uniform heating. In terms of mixing, the single stirring shaft structure limits the movement of raw materials to a localized area, leading to insufficient overall mixing and poor uniformity between raw material particles. These two problems combined make it difficult to effectively pre-treat the raw materials during the storage stage, requiring additional time for temperature adjustment and mixing before entering the subsequent extrusion process. This not only prolongs the production cycle but also affects the consistency of the final product quality. Utility Model Content

A filter screen is fixedly connected to the bottom of the processing chamber.

[0008] By adopting the above technical solution, the second motor drives the positive and negative cross-textured rod to rotate, causing the baffle to slide back and forth in the slot, and the connecting block to achieve uniform and equal material feeding. Then, the heating tube is controlled by the control display to heat the material evenly, and the first motor drives the second rotating shaft and the folding blade to rotate through the transmission mechanism. At the same time, the sliding cooperation between the second rotating shaft and the corrugated cylinder drives the folding blade to swing up and down, thereby realizing the pretreatment of uniform feeding, precise heating and full stirring of the raw material in the storage bin.

[0009] Preferably, the external rotating shaft is rotatably connected to the top of the processing chamber.

[0010] By adopting the above technical solution, the bottom end of motor one is movably connected to the top of the processing chamber to ensure the stability of motor one during operation; the external rotatable connection of the rotating shaft one is to the top of the processing chamber to provide rotational support for the rotating shaft one.

[0011] Preferably, the slider is slidably connected to the inner wall of the wave groove cylinder, the outer top end of the second rotating shaft is slidably connected to the inner wall of the wave groove cylinder, and the outer side of the first rotating shaft is slidably connected to the inner wall of the second rotating shaft.

[0012] By adopting the above technical solution, the axial relative sliding of rotating shaft one and rotating shaft two is achieved, thus satisfying the swing requirement.

[0013] Preferably, the top end of the spring is fixedly connected to the top end of the inner wall of the sleeve shaft, and the bottom end of the spring is fixedly connected to the bottom end of the rotating shaft.

[0014] By adopting the above technical solution, the orientation of the spring is determined, and elastic support is provided.

[0015] Preferably, the top end of the corrugated cylinder is fixedly connected to the top end of the inner wall of the processing chamber.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. A second motor drives a cross-grained rod to rotate, causing a baffle to slide back and forth within the groove. This, combined with a connecting block, ensures uniform and equal material feeding. A control display then regulates the heating element to uniformly heat the material. A first motor, via a transmission mechanism, drives a second rotating shaft and folding blades to rotate. Simultaneously, the sliding contact between the second rotating shaft and the corrugated cylinder causes the folding blades to oscillate up and down. This achieves simultaneous uniform feeding, precise heating, and thorough mixing of the raw material within the storage silo, effectively improving the temperature stability and mixing uniformity of the raw material, providing high-quality pre-treated raw materials for subsequent extrusion processing. 2. The raw materials, after being processed by electronic control valves, are driven by a filter screen. The filter screen filters out the residue generated during the mixing process, selecting the raw materials that meet the requirements and guiding them out through the conveying pipe. Simultaneously, the discharge speed is adjusted according to demand using a control display. This achieves precise filtration and conveying of pre-treated raw materials, ensuring continuous and stable feeding to the extruder, effectively reducing the impact of feeding fluctuations on production, and significantly improving production efficiency and processing stability.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0024] Example: Reference Figures 1-2An extruder storage silo with pretreatment function includes a processing silo 1, which provides a closed processing space for raw material pretreatment, ensuring that the pretreatment process is carried out in a controllable environment. A control display 2 is installed on the front side of the processing silo 1, which receives user commands and displays the equipment's operating status, enabling intelligent control of the pretreatment process. A motor 3 is fixedly connected to the top of the processing silo 1, providing power output to the stirring mechanism and driving subsequent transmission components. A pulley 4 is fixedly connected to the output end of the motor 3, which transmits the power of the motor 3 to a second pulley 5 via a rubber connecting belt 6, achieving power distribution. The top of the processing silo 1... A second pulley 5 is rotatably connected to the end of the shaft. The second pulley 5 works in conjunction with the first pulley 4, rotating synchronously via a rubber connecting belt 6 to ensure that the two rotating shafts 7 receive synchronous power. A rubber connecting belt 6 is fitted around the outside of both the first pulley 4 and the second pulley 5. The rubber connecting belt 6 connects the first pulley 4 and the second pulley 5, enabling power transmission. Its rubber material buffers the impact force during transmission, reducing component wear. A rotating shaft 7 is fixedly connected to the middle of both the first pulley 4 and the second pulley 5. The rotating shaft 7 transmits the rotational power from the pulleys to the second rotating shaft 9, providing rotational power for the stirring component. A fixing plate 8 is fixedly connected inside the control processing chamber 1, used for fixing supports. The rotating shaft 29 and the corrugated trough cylinder 14 are supported to ensure their stable position during operation and improve the stability of equipment operation. Two rotating shafts 29 are rotatably connected to the middle of the fixed plate 8. These shafts 29 can rotate around the fixed plate 8, simultaneously driving the folded blades 10 to perform stirring operations. Their rotation provides the basic motion for raw material stirring. Multiple folded blades 10 are provided on the outside of the rotating shaft 29. The folded blades 10 rotate with the rotating shaft 29 and swing up and down, increasing the contact area with the raw materials, enhancing the stirring effect, and making the raw materials more uniformly mixed. Two sliders 11 are fixedly connected to the top outer side of the rotating shaft 29. The sliders 11 are slidably connected within the corrugated trough of the corrugated trough cylinder 14. When the rotating shaft 29 rotates, the sliders 11... 1. Moving along the wave groove trajectory, forcing the second rotating shaft 9 to swing up and down; the top of the second rotating shaft 9 is provided with a sleeve shaft 12, which provides sliding space for the first rotating shaft 7, allowing the first rotating shaft 7 to slide up and down relative to the second rotating shaft 9, while transmitting rotational power; the outside of the first rotating shaft 7 is fitted with a spring 13, which applies a downward elastic force to the second rotating shaft 9 through elastic deformation, ensuring that the slider 11 always fits against the inner wall of the wave groove of the wave groove cylinder 14, ensuring stable and reliable up and down swinging action; the top of the fixed plate 8 is fixedly connected to two wave groove cylinders 14, and the wave grooves on the inner wall of the wave groove cylinder 14 provide a motion trajectory for the slider 11, which guides the second rotating shaft 9 to swing up and down while rotating.

[0025] Reference Figures 1-2The external rotatable connection of rotating shaft 7 to the top of processing chamber 1 ensures its free rotation, reduces rotational resistance, and improves power transmission efficiency. Sliding slider 11 is slidably connected to the inner wall of the wave groove cylinder 14. The sliding engagement of slider 11 and wave groove cylinder 14 converts the trajectory of the wave groove into the up-and-down oscillation of rotating shaft 9, achieving a combined stirring and oscillation motion. The outer side of the top of rotating shaft 9 is slidably connected to the inner wall of wave groove cylinder 14. This slidable connection provides guidance for the up-and-down oscillation of rotating shaft 9, enhancing motion stability. The external rotatable connection of rotating shaft 7 to the inner wall of rotating shaft 9... The sliding connection between rotating shaft 7 and rotating shaft 9 allows rotating shaft 9 to move up and down relative to rotating shaft 7 without affecting the transmission of rotational power. The top end of spring 13 is fixedly connected to the top end of the inner wall of sleeve shaft 12, and the bottom end of spring 13 is fixedly connected to the bottom end of rotating shaft 7. The two ends of spring 13 are fixedly connected to each other, so that it can stably apply elastic force to sleeve shaft 12 and rotating shaft 7, ensuring close contact between slider 11 and wave groove. The top end of wave groove cylinder 14 is fixedly connected to the top end of the inner wall of processing chamber 1. The fixed connection between wave groove cylinder 14 and processing chamber 1 fixes its position, providing a stable motion trajectory reference for slider 11 and ensuring consistent swinging motion.

[0026] Reference Figures 3-4A connecting block 15 is fixedly connected to the top of the processing chamber 1 and the middle of the fixed plate 8. The connecting block 15 connects the top of the processing chamber 1 and the fixed plate 8 to form a raw material inlet channel, guiding the raw material into the processing area. A slot 16 is opened on the left side of the connecting block 15, which provides sliding space for the baffle 20, allowing the baffle 20 to slide back and forth in it, thereby controlling the amount of raw material fed. A connecting plate 17 is fixedly connected to the left side of the top of the processing chamber 1. The connecting plate 17 provides fixed support for the second motor 18, ensuring that the second motor 18 remains stable during operation and avoiding vibration affecting its operating accuracy. The second motor 18 is fixedly connected to the rear end of the connecting plate 17. The second motor 18 provides rotational power to the positive and negative cross-textured rod 19, which is the power source for the reciprocating motion of the baffle 20. The output end of the second motor 18 is fixedly connected to the positive and negative cross-textured rod 19. The positive and negative cross-textured rod 19 cooperates with the baffle 20 through the positive and negative cross-textured patterns on its surface, converting its own rotational motion into the motion of the baffle 20. The reciprocating cross sliding; the external thread of the positive and negative cross-textured rod 19 is connected to a baffle 20, which reciprocates cross-sliding within the slot 16, adjusting the size of the material feeding channel of the connecting block 15 to achieve uniform and equal material feeding; the processing chamber 1 has an internal interlayer groove 21, which provides installation space for the heating tube 22, allowing the heating tube 22 to be evenly distributed inside the processing chamber 1, ensuring heating uniformity; the interlayer groove 21 is equipped with a heating tube 22, which generates heat after being energized, and transfers the heat to the raw material in the processing chamber 1 through the interlayer groove 21, achieving uniform heating of the raw material; the top of the processing chamber 1 is equipped with a filter screen 24, which can filter impurities in the raw material, preventing impurities from entering subsequent processing stages and ensuring the purity of the raw material; the bottom of the processing chamber 1 is fixedly connected to an electronic control valve 23, which can adjust the opening and closing degree through the control display 2 to achieve precise control of the raw material discharge speed and ensure stable material supply.

[0027] Reference Figures 3-4 The baffle 20 is externally slidably connected to the inner wall of the slot 16. The sliding fit between the baffle 20 and the slot 16 ensures smooth reciprocating motion and guarantees the stability of the material feeding control. The control display 2 is electrically connected to the electronic control valve 23. The electrical connection between the control display 2 and the electronic control valve 23 enables the monitoring and control of the working status of the electronic control valve 23, and timely prompts for cleaning or replacement. The control display 2 is electrically connected to the heating tube 22. The electrical connection between the control display 2 and the heating tube 22 allows the operator to adjust the power of the heating tube 22 through the control display 2, and accurately control the heating temperature of the raw materials.

[0028] The implementation principle of this application embodiment is as follows: When pretreatment is required, motor 18 is first started to drive the cross-textured rod 19 to rotate, causing the cross-textured rod 19 to drive the baffle 20 to slide back and forth on the inner wall of the slot 16 through the cross-textured pattern. At this time, the material is introduced and evenly fed through the connecting block 15. Then, the heating tube 22 is controlled by the control display 2 to evenly heat the material entering the processing chamber 1. After that, motor 3 is started, which drives pulley 4 and pulley 5 to rotate through the rubber connecting belt 6. This causes shaft 7 to drive shaft 9 and the folded blades 10 on shaft 9 to stir through the sleeve shaft 12. While stirring, the shaft 7 slides... The rotating shaft 29 is located within the sleeve shaft 12, and the slider 11 is confined within the wave groove of the wave groove cylinder 14 when the rotating shaft 29 rotates. Therefore, the rotating shaft 29 drives the folding blade 10 to stir while simultaneously oscillating up and down. This ensures that the raw material is heated evenly and stirred thoroughly, allowing the raw material to complete the pretreatment step in the storage bin, thus improving the temperature and mixing uniformity of the raw material. After processing, the raw material is filtered through the filter screen 24 and finally transferred to the subsequent processing machine by opening the electronic control valve 23. The control display 2 can adjust the discharge speed according to the user's needs, ensuring continuous and stable feeding of the extruder and improving production efficiency.
