[0001] The invention relates to the technical field of plastic processing, in particular to an energy-saving and environment-friendly plastic processing machine. Background Art

The extruder is composed of a barrel, a screw, etc. It heats the molten plastic and extrude it continuously to produce a variety of products. It is efficient but the equipment cost is high. The injection molding machine is composed of injection molding and mold clamping parts. The molten plastic is injected into the mold under high pressure to form the product.

In addition, existing extruders are not convenient for adjusting the extrusion force. When dealing with different materials, the extrusion force is too small, requiring additional energy or process processing, resulting in waste; if the extrusion force is too large, it may damage the structural performance of the material and also requires adjustment, which consumes energy and time, indirectly affecting production efficiency and energy utilization efficiency.

[0034] Example

[0035] See also Figure 1-Figure 4 As shown, the purpose of this embodiment is to provide an energy-saving and environmentally friendly plastic processing machine, including a base 1, a support 11 and a bracket 12 are fixedly connected to the top of the base 1, a pneumatic component 13 is arranged between the support 11 and the bracket 12, and an extrusion head 16 is fixedly connected to the end of the pneumatic component 13 away from the bracket 12;

[0036] A feeding port 14 is provided at the top of the pneumatic component 13, and a rotating component 15 is provided inside the pneumatic component 13. The rotating component 15 is movably connected between the support 11 and the inside of the pneumatic component 13;

[0037] The rotating assembly 15 is used to convey and stir the material, and the pneumatic assembly 13 is used to adjust the size of the feed opening 14. The pneumatic assembly 13 also adjusts the length of the rotating assembly 15. The rotating assembly 15 guides the flow direction of the material and stabilizes the flow of the extruded material.

[0038] The improvement of this embodiment is that: during the operation of the plastic extruder, the rotating component 15 continuously rotates to push the material forward and mix it, and the rotating component 15 adjusts the extrusion force and extrusion distance. The appropriate extrusion pressure can ensure the dimensional accuracy and density of the product, while avoiding equipment damage and energy waste caused by excessive pressure;

[0039] According to the characteristics of the material, the requirements of the production speed and different process parameters, the size of the feed port 14 can be flexibly changed through the pneumatic component 13; and by controlling the pressure and action of the pneumatic component 13, the thread pitch of the rotating component 15 is also adjusted; when the thread pitch is small, the forward space of the material in the screw becomes narrower. As the screw rotates, the smaller thread pitch allows the material to be more tightly compressed in the screw, thereby increasing the extrusion pressure and better meeting the production requirements of thin-walled pipes; when the thread pitch is large, the flow space of the material in the screw increases, and the resistance is reduced accordingly, so that the material can flow more smoothly in the screw without the need for the screw to apply excessive pressure to push; for products such as foam materials and soft plastics that have lower requirements for extrusion pressure, a larger thread pitch can avoid excessive pressure on the material, prevent the pore structure of the foam material from being destroyed or the soft plasticization from being over-plasticized and losing elasticity;

[0040] First, the specific structure of the pneumatic assembly 13 is disclosed. The pneumatic assembly 13 includes an extrusion cylinder 130, which is fixedly connected to the top of the bracket 12. A rotating assembly 15 is provided inside the extrusion cylinder 130. A feeding port 14 is fixedly connected to the top of the extrusion cylinder 130. An extrusion head 16 is fixedly connected to the end of the extrusion cylinder 130.

[0041] The outer wall of the extrusion cylinder 130 is fixedly connected with a sleeve 131, and a piston 133 is movably connected between the inner wall of the sleeve 131 and the outer wall of the extrusion cylinder 130. Two cylinders 134 are fixedly connected to the ends of the piston 133. The cylinders 134 pass through the sleeve 131 and are fixedly connected to the top of the support 11. The outer wall of the piston rod of the cylinder 134 is fixedly connected with a push plate 135. The inner wall of the extrusion cylinder 130 is fixedly connected with an air bag 132 near the extrusion head 16. The air bag 132 is threaded and made of elastic silicone.

[0042] See also Figure 3 , Figure 4 and Figure 7 As shown, the piston rod of the cylinder 134 is extended and retracted to push the piston 133 to move between the inner wall of the sleeve 131 and the outer wall of the extrusion cylinder 130. The movement of the piston 133 squeezes the gas between the inner wall of the sleeve 131 and the outer wall of the extrusion cylinder 130 into the airbag 132, so that the airbag 132 expands along its thread shape, forming a gas thread on the inner wall of the extrusion cylinder 130, increasing the friction and traction on the material, and promoting the material to move more smoothly toward the extrusion head 16; especially for some materials with high viscosity or poor fluidity, the thread can effectively overcome the resistance of the material in the barrel, thereby improving the conveying speed and stability;

[0043] The airbag 132 is in a threaded shape and is made of elastic silicone material. According to its material characteristics, the airbag 132 has good elasticity, high temperature resistance, corrosion resistance and sealing performance. It can be deformed under a large external force and can return to its original shape after the external force is removed. The silicone rubber is made into a threaded shape, and an extrusion force is applied to the silicone rubber thread by the rotating component 15 to deform it. When the external force is removed, the silicone rubber thread returns to its original shape.

[0044] Secondly, the specific structure of the rotating assembly 15 is disclosed. The rotating assembly 15 includes a motor 150, which is fixedly connected to the top of the base 1. The end of the output shaft of the motor 150 is fixedly connected to a rotating rod 151, which is movably connected between the support 11 and the inside of the extrusion cylinder 130. The outer wall of the rotating rod 151 is provided with a spiral plate 152, and one end of the spiral plate 152 is fixedly connected to a sliding member 153, which is movably connected between the outer wall of the rotating rod 151 and the inner wall of the extrusion cylinder 130.

[0045] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the output shaft of the motor 150 drives the rotating rod 151 to rotate, and the rotating rod 151 drives the spiral plate 152 and the sliding member 153 to rotate simultaneously, and the spiral plate 152 rotates to push the material forward, and at the same time, highly uniform mixing of the material is achieved during the rotation process;

[0046] Among them, one end of the spiral plate 152 is fixedly connected to the inside of the sliding member 153, and the other end of the spiral plate 152 is fixedly connected to the outer wall of the rotating rod 151. The spiral plate 152 is made of metal; according to its material characteristics, it has good elasticity and deformability; the metal bellows is made into a threaded shape to make a spiral plate 152, which is sleeved on the rotating rod 151, and the sliding member 153 moves on the rotating rod 151 to apply an extrusion force to the spiral plate 152, so that it is deformed in the axial direction, thereby changing the thread pitch. When the external force is removed, the elasticity of the spiral plate 152 makes it return to its original shape, and the thread pitch also returns to the initial state;

[0047] Among them, a slide groove is provided on the rotating rod 151, and an electromagnet is provided between the slide groove of the rotating rod 151 and the spiral plate 152. The slide groove on the rotating rod 151 provides a track for the movement of the electromagnet, and the shape and size of the slide groove match the appearance of the electromagnet. The working principle of the electromagnet is known to those skilled in the art. The electromagnet is a device that uses electric current to generate a magnetic field. Its magnetism can be adjusted by controlling the magnitude and direction of the current, and it has the characteristic of strong controllability. The electromagnet has a strong magnetic force when it is powered on, and the magnetism disappears after the power is turned off. It can be designed into various shapes and sizes according to different application requirements, and is suitable for various complex working environments.

[0048] When the electromagnet is energized, a magnetic field is generated in the coil; this magnetic field interacts with other magnetic components on the rotating rod 151 or an external magnetic field to generate a magnetic force; due to the effect of the magnetic force, the electromagnet is subjected to a force along the direction of the slide groove, and this force pushes the electromagnet to move in the slide groove; and during the movement of the electromagnet, in order to avoid the friction force from the slide groove and air resistance, etc., a lubricant is applied to the slide groove to reduce the friction coefficient; at the same time, a sensor is also arranged at a specific position of the slide groove to realize the positioning and stopping of the electromagnet; when the electromagnet moves to a specific position, the sensor detects the position of the electromagnet and sends a signal to control the on and off of the current, so that the electromagnet stops at the desired position.

[0049] The sliding member 153 includes a large ring 1530, which is movably connected between the inner wall of the extrusion cylinder 130 and the outer wall of the airbag 132. A slider 1532 is movably connected inside the slide groove of the outer wall of the rotating rod 151. Small rings 1531 are fixedly connected between the ends of the sliders 1532. One end of the spiral plate 152 is fixedly connected between the outer wall of the small ring 1531 and the inner wall of the large ring 1530.

[0050] When the airbag 132 is in an expanded state, the spiral plate 152 and the sliding member 153 are continuously rotated, so that the large ring 1530 in the sliding member 153 moves along the thread of the airbag 132, and the large ring 1530 drives one end of the spiral plate 152 to move, so that the spiral plate 152 drives the small ring 1531 to move on the outer wall of the rotating rod 151, and the moving position of the small ring 1531 is limited by the sliding member 1532; thereby, the small ring 1531 and the large ring 1530 move to apply a compressive and retractive force to the spiral plate 152, and the length of the spiral plate 152 is adjusted, thereby adjusting the thread pitch inside the spiral plate 152;

[0051] When the pitch of the spiral turns is small, the forward space of the material in the screw becomes narrower, and as the screw rotates, the extrusion effect on the material becomes more obvious; for example, when producing thin-walled pipes, a higher extrusion pressure is required to ensure that the wall thickness of the pipe is uniform and has sufficient strength; a smaller spiral pitch allows the material to be more tightly compressed in the screw, thereby increasing the extrusion pressure and better meeting the production requirements of thin-walled pipes; for high-density plates, a smaller spiral pitch can make the material subject to greater extrusion force during the extrusion process, thereby improving the density of the plate;

[0052] In addition, a smaller coil pitch means that the material has a shorter flow path in the screw, and the number of shears experienced per turn increases. This frequent shearing action will cause greater friction and resistance inside the material. In order to overcome these resistances, the screw needs to exert greater force to push the material forward, resulting in an increase in extrusion pressure. For example, when processing some high-viscosity plastics, a smaller coil pitch can increase the plasticization degree of the material by increasing the shear force, while also increasing the extrusion pressure.

[0053] When the coil pitch is larger, the flow space of the material in the screw increases, and the resistance is reduced accordingly. The material can flow more smoothly in the screw without the need for the screw to exert excessive pressure to push it. For products such as foaming materials and soft plastics that require low extrusion pressure, a larger coil pitch can avoid excessive pressure on the material, prevent the foaming material's pore structure from being destroyed, or prevent the soft plastic from being over-plasticized and losing elasticity. For example, when producing foaming materials, the extrusion pressure needs to be controlled to maintain the integrity of the pores. A larger coil pitch can reduce the pressure of the material in the screw, which is conducive to the smooth progress of the foaming process.

[0054] In addition, a larger coil pitch enables the screw to convey more material per revolution, which means that at the same speed, the material flow rate increases while the extrusion pressure is relatively reduced; for products such as soft plastics, a larger flow rate can meet production needs while avoiding the adverse effects of excessive extrusion pressure on product performance; for example, when producing soft plastic films, a larger coil pitch can improve production efficiency while ensuring the quality of the film;

[0055] In order to adjust the size of the material flow of the material discharge port 14 according to different material characteristics, a baffle 140 is movably connected to the inner wall of the material discharge port 14, and a rotating plate 141 is fixedly connected to the ends of the rotating shafts passing through the material discharge port 14 at both ends of the baffle 140 near the top, and the outer wall of the rotating plate 141 is movably connected to the outer wall of the push plate 135;

[0056] See also Figure 8As shown, the piston rod of the cylinder 134 is extended and retracted to drive the push plate 135 to move forward and backward. When the push plate 135 moves, it pushes the rotating plate 141 to reverse. The reverse rotation of the rotating plate 141 drives the baffle 140 to tilt inside the discharge port 14, thereby adjusting the size of the space between the baffle 140 and the inner wall of the discharge port 14; when the space of the discharge port 14 is small, the passage for the material to enter the extruder becomes narrower, which limits the flow space of the material after entering the extruder; the material needs to overcome greater resistance when entering the extruder through the discharge port 14, and this resistance comes from the friction between the discharge port 14 and the material and the mutual extrusion of the material itself; for the production of products such as thin-walled pipes and high-density plates that require higher extrusion pressure, the smaller discharge port 14 can provide sufficient resistance to ensure that the material is fully extruded and plasticized in the extruder to meet the quality requirements of the product;

[0057] The larger discharge port 14 provides a more spacious entry channel for the material, so that the material can flow into the extruder more smoothly, reducing congestion and accumulation of the material at the entrance, and reducing the resistance to the material flow; for example, when producing products such as foam materials and soft plastics that require lower extrusion pressure, the larger discharge port 14 can prevent the material from destroying its pore structure or affecting its softness due to excessive extrusion, and the material can flow in the extruder at a lower pressure, thereby achieving the desired extrusion effect.

[0058] In summary, the working principle of this solution is as follows:

[0059] During the operation of the plastic extruder, first, the piston rod of the cylinder 134 performs a telescopic action, driving the push plate 135 to move forward and backward; when the push plate 135 moves, it will push the rotating plate 141 to reverse; the reversal of the rotating plate 141 will then drive the baffle 140 to tilt inside the discharge port 14, thereby the size of the space between the baffle 140 and the inner wall of the discharge port 14 can be flexibly adjusted; this adjustment function is extremely convenient, and can accurately adjust the size of the discharge port 14 and the descending speed of the material according to the characteristics of different materials; whether it is for high-viscosity materials that need to be discharged slowly, or for low-viscosity materials that can speed up the discharge speed, ideal control can be achieved;

[0060] Secondly, the output shaft of the motor 150 drives the rotating rod 151 to rotate, and the rotating rod 151 drives the spiral plate 152 and the sliding member 153 to rotate simultaneously; the rotation of the spiral plate 152 can, on the one hand, effectively push the material forward, ensuring that the material is continuously and stably conveyed toward the extrusion head 16, and avoiding the accumulation or blockage of the material in the barrel; on the other hand, during the rotation process, the spiral plate 152 achieves highly uniform mixing of the material, so that the materials of different components are fully integrated, whether it is various additives, fillers, or different types of plastic particles, can achieve a highly uniform mixing state, thereby improving the performance stability of the product;

[0061] Furthermore, the extension and retraction of the piston rod of the air cylinder 134 can also push the piston 133 to move between the inner wall of the sleeve 131 and the outer wall of the extrusion cylinder 130; the movement of the piston 133 squeezes the gas between the inner wall of the sleeve 131 and the outer wall of the extrusion cylinder 130 into the airbag 132, so that the airbag 132 expands along its thread shape; when the airbag 132 is in an expanded state, a gas thread is formed on the inner wall of the extrusion cylinder 130; this gas thread can increase the friction and traction on the material. For some materials with high viscosity or poor fluidity, the thread can effectively overcome the resistance of the material in the barrel, significantly improving the conveying speed and stability;

[0062] Finally, when the airbag 132 is inflated, the spiral plate 152 and the sliding member 153 continue to rotate; wherein, the large ring 1530 in the sliding member 153 will move along the thread of the airbag 132, and the movement of the large ring 1530 will drive one end of the spiral plate 152 to move; the movement of the spiral plate 152 will drive the small ring 1531 to move on the outer wall of the rotating rod 151, and at the same time, the moving position of the small ring 1531 is limited by the slider 1532; in this way, the movement of the small ring 1531 and the large ring 1530 will exert an extrusion and expansion force on the spiral plate 152, thereby realizing the adjustment of the length of the spiral plate 152; in this way, the thread pitch inside the spiral plate 152 can be accurately adjusted so that it can adapt to different material characteristics, whether it is high-viscosity material or low-viscosity material, it can be efficiently extruded at the optimal thread pitch.
