Among them, how to effectively control the melting process of plastic particles in the conveying pipe, reduce the melt pressure, prevent melt blockage, and improve the uniformity of the melt is the key to enhancing the performance of plastic extrusion equipment. In addition, the hot melting effect of plastic particles during the extrusion process directly affects the physical properties of the final product.

When the motor is started, the rotating shaft and the first gear will be driven to rotate. After the first gear rotates, the second gear in the mounting frame will be driven to rotate. As the second gear rotates, the gear set will be driven to start rotating, so that the two gears meshing with each other on the gear set start to make relative rotational motion, that is, the toggle rod on the gear set drives the two fluctuating plates to rotate relatively, and then the plastic particles put into the feed frame are intermittently put into the conveying pipe, and the plastic particles are gradually moved to the output end of the conveying pipe through the conveying of the screw in the conveying pipe, and are heated and melted during the movement, and finally transported in a molten state from the output end of the conveying pipe to the die head to form a protective film through film blowing.

At the same time, after the melt enters the flow reduction tube, it will be conveyed to the die head through the diverter hole on the diverter column, and at the same time, a part of it will be separated and output to the die head through the matching groove on the positioning ring. The melt is diverted by the mutual cooperation between the diverter hole and the matching groove, so that the distribution of the melt is more uniform, and the overall quality and performance of the product are improved. At the same time, the diversion design helps to achieve the stability of material flow and the uniformity of the discharge speed of each material strip, which helps to improve production efficiency and output consistency.

When plastic particles accumulate between adjacent guide plates, they will follow part of the melt through the filter holes on the flow reduction tube into the filter ring, that is, the filter ring is eventually filled with a mixture of melt and plastic particles, wherein the melt continues to be input into the polymerization ring through the gap between the filter ring and the flow reduction tube, and is finally mixed with the melt passing through the diversion column and conveyed to the die head for blown film molding, while the plastic particles are blocked in the filter ring.

[0014] The present invention provides a PE protective film plastic extrusion device with a diversion function. It has the following beneficial effects: 1. The PE protective film plastic extrusion equipment with diversion function can automatically block and intermittently input plastic particles when the screw rotates to transport the raw materials by setting a gear set and a toggle plate, thereby reducing the pressure of the material in the conveying pipe, reducing the melt pressure, ensuring the smooth input of the melt, avoiding the blockage of the melt in the conveying pipe to reduce production efficiency, and also giving the plastic particles enough space in the conveying pipe for hot melting, greatly improving the hot melting effect of the plastic particles, that is, greatly improving the overall quality of the melt, and then improving the overall quality of the PE protective film.

[0015] 2. The PE protective film plastic extrusion equipment with diversion function, when the melt is conveyed through the diversion hole, a tangential force will be generated with the diversion hole, and then with the continuous conveying of the melt, the plastic particles will be conveyed to the outside of the diversion column through the inclined surface of the diversion column, so as to avoid the accumulation of plastic particles at the diversion hole, causing blockage and reducing production efficiency. When the plastic particles are conveyed outside the diversion column along with part of the melt, the existence of the isolation plate will divide the melt into three strands and convey them through the matching groove on the positioning ring. At this time, due to the existence of the guide plate, the normal melt will enter the matching groove through the guide plate for normal conveying, and the plastic The particles will be blocked by the guide plates and thus accumulate in the gaps between adjacent guide plates along the edges of the guide plates, thereby blocking the plastic particles and preventing them from passing through the diverter column and affecting the production quality. The rotation of the screw will drive the stirring rod to rotate, and the rotation of the stirring rod will drive the stirring plate to rotate through the mounting plate, thereby causing the stirring plate to reciprocate between the diverter holes through the slide groove, thereby unblocking the diverter holes. The diverter holes are automatically cleaned during the production process to avoid blockage of the diverter holes that reduces production efficiency, and to prevent blockage of the diverter holes that increases the melt pressure in the flow reduction tube and reduces product quality.

[0016] 3. The PE protective film plastic extrusion equipment with diversion function can realize automatic interception and collection of plastic particles during the production process by setting filter rings and sealing rings, so as to prevent plastic particles from following the melt into the die head and affecting product quality. At the same time, by setting discharge grooves and dislocation grooves, the plastic particles can be uniformly recycled after production is completed, which can not only improve the continuity of production, but also can re-melt the recycled plastic particles for secondary utilization, greatly reducing the waste generation rate and reducing the production cost of the enterprise.

[0020] First embodiment: Figures 1 to 8 As shown, the present invention provides a technical solution: a PE protective film plastic extrusion device with a diversion function, comprising a bottom plate 1, a mounting frame 2 is fixedly connected to the upper surface of the bottom plate 1, one end of the mounting frame 2 is fixedly connected to a motor 3, and the other end of the mounting frame 2 is fixedly connected to a conveying pipe 4, the bottom end of the motor 3 is fixedly connected to the upper surface of the bottom plate 1, the bottom of the conveying pipe 4 is fixedly installed on the upper surface of the bottom plate 1 away from the motor 3, the top of the conveying pipe 4 close to the motor 3 is fixedly connected to a feed frame 5, and a die head 6 is arranged on the side of the conveying pipe 4 away from the motor 3, and also includes: The conveying mechanism 7 is fixedly installed inside the conveying pipe 4 and is also installed in the installation frame 2. The conveying mechanism 7 is used to melt and convey the plastic particles. A diverter mechanism 8, which is fixedly mounted at the end of the conveying mechanism 7, and is used to divert and convey the melted plastic particles; The conveying mechanism 7 includes a rotating shaft 71, one end of which is rotatably connected to the output end of the motor 3, and the other end of the rotating shaft 71 is fixedly connected to a first gear 72, which is arranged in the mounting frame 2, and the outer surface of the first gear 72 is rotatably engaged with a second gear 73, and the second gear 73 is rotatably connected to the inner wall of the mounting frame 2, and the top outer surface of the second gear 73 is rotatably engaged with a gear set 74, wherein the gear set 74 is composed of two identical gears meshing with each other, and one end of the gear set 74 away from the diversion mechanism 8 is rotatably connected to the inner surface of the mounting frame 2, and one end of the gear set 74 close to the diversion mechanism 8 is fixedly connected to a toggle rod 75, and a toggle plate 76 is fixedly installed on the outer surface of the toggle rod 75, and one end of the rotating shaft 71 away from the motor 3 is fixedly connected to a screw 77.

[0021] The screw 77 is arranged in the conveying pipe 4, the outer end of the spiral plate on the screw 77 is in contact with the inner wall of the conveying pipe 4, the toggle plate 76 is staggered, the toggle plate 76 is arranged in the feed frame 5, and the toggle plate 76 is also arranged just above the side of the screw 77 close to the motor 3.

[0022] During operation, when it is necessary to produce the PE protective film, the plastic particles can be put in from the feed frame 5, and the motor 3 can be started at the same time. When the motor 3 is started, the rotating shaft 71 and the first gear 72 will be driven to rotate. After the first gear 72 rotates, the second gear 73 in the mounting frame 2 will be driven to rotate.

By arranging the gear set 74 and the toggle plate 76, the plastic particles can be automatically blocked and intermittently input when the screw 77 rotates to convey the raw materials, thereby reducing the pressure of the material in the conveying pipe 4, reducing the melt pressure, ensuring the smooth input of the melt, avoiding blockage of the melt in the conveying pipe 4 to reduce production efficiency, and also giving the plastic particles enough space in the conveying pipe 4 for hot melting, greatly improving the hot melting effect of the plastic particles, that is, greatly improving the overall quality of the melt, and then improving the overall quality of the PE protective film.

[0023] Second embodiment: Figures 1 to 8 As shown, the diversion mechanism 8 includes a flow reducing tube 81, which is fixedly connected to the end of the conveying tube 4 away from the motor 3. The flow reducing tube 81 is configured as a truncated cone, and a diversion column 82 is provided inside the flow reducing tube 81. The diversion column 82 is penetrated by a diversion hole 83.

[0024] A plurality of diverter holes 83 are arranged at fixed intervals around the central axis of the diverter column 82. The surface of the diverter column 82 on one side close to the screw 77 is arranged to be inclined. A positioning ring 84 is fixedly sleeved on the outer surface of the diverter column 82 on the side away from the screw 77. The surface of the positioning ring 84 on the side away from the diverter column 82 is fixedly connected to the inner surface of the flow reducing pipe 81 on the end away from the conveying pipe 4.

[0025] A matching groove 85 is formed through the outer surface of the positioning ring 84. Three matching grooves 85 are formed at fixed intervals around the central axis of the positioning ring 84. A guide plate 86 is provided on the side of the matching groove 85 close to the screw 77. The guide plate 86 is configured as a special-shaped plate. The overall appearance of the guide plate 86 is configured as a nearly triangular shape. One end of the guide plate 86 away from the screw 77 is fixedly connected to the edge outer surface of the positioning ring 84 close to the screw 77, and the outer surface of the guide plate 86 away from the diversion column 82 is fixedly attached to the inner surface of the flow reduction tube 81.

[0026] There are three guide plates 86 arranged at a fixed interval along the central axis of the positioning ring 84. On the opposite side of the guide plate 86 away from the positioning ring 84, there is an isolation plate 87. The isolation plate 87 is fixedly connected to the outer surface of the flow dividing column 82. There are three isolation plates 87 arranged at a fixed interval around the central axis of the flow dividing column 82. The isolation plate 87 is set as a special-shaped plate, and one end of the isolation plate 87 close to the screw rod 77 is set to be inclined.

[0027] A stirring rod 88 is rotatably connected through the inside of the flow dividing column 82. One end of the stirring rod 88 away from the positioning ring 84 is fixedly connected to one end of the screw rod 77 close to the flow dividing column 82. A chute 89 is formed on the outer surface of the flow dividing column 82 on the side away from the screw rod 77. The chute 89 is set as a circular tube type, and the flow dividing holes 83 are interconnected through the chute 89. One end of the stirring rod 88 away from the screw rod 77 is fixedly connected with a mounting disc 810. The mounting disc 810 is rotatably attached to the outer surface of the flow dividing column 82 at the end away from the screw rod 77. The inner surface of the mounting disc 810 is fixedly connected with stirring plates 811. There are three stirring plates 811 arranged at a fixed interval around the central axis of the flow dividing column 82. The stirring plates 811 are set as strip-shaped, and the stirring plates 811 are slidably arranged in the chute 89.

[0028] During operation, when the melt passes through the delivery pipe 4, it enters the flow-reducing pipe 81. Since the internal cavity of the flow-reducing pipe 81 gradually decreases, the melt is gradually squeezed when it enters the flow-reducing pipe 81. Thus, in cooperation with the deflector plate 76, the melt that is stretched and melted in the delivery pipe 4 is aggregated and squeezed in the flow-reducing pipe 81, thereby improving the continuity of the melt output, ensuring the overall quality of the PE protective film. At the same time, after the melt enters the flow-reducing pipe 81, it is transported to the die head 6 through the diversion holes 83 on the diversion column 82, and at the same time, a part of it is output to the die head 6 through the mating grooves 85 on the positioning ring 84. The melt is diverted through the mutual cooperation between the diversion holes 83 and the mating grooves 85, making the distribution of the melt more uniform, improving the overall quality and performance of the product. At the same time, the diversion design helps to achieve the stability of the material flow and the uniformity of the discharge speed of each strip, contributing to improving the production efficiency and the consistency of the output. When the melt is transported in the flow-reducing pipe 81, the unmelted plastic particles will partially accumulate at the diversion holes 83 of the diversion column 82. By setting the surface of the diversion column 82 close to the screw 77 as an inclined surface, when the melt is transported through the diversion holes 83, a tangential force will be generated between the melt and the diversion holes 83. Then, as the melt continues to be transported, the plastic particles will be transported to the outside of the diversion column 82 through the inclined surface of the diversion column 82, preventing the plastic particles from accumulating at the diversion holes 83 and causing blockage to reduce the production efficiency. When the plastic particles are transported outside the diversion column 82 along with a part of the melt, due to the presence of the isolation plate 87, the melt will be divided into three strands and transported through the mating grooves 85 on the positioning ring 84. At this time, due to the presence of the guide plate 86, the normal melt will enter the mating grooves 85 through the guide plate 86 for normal transportation, while the plastic particles will accumulate in the gaps between adjacent guide plates 86 along the edge of the guide plate 86 due to the blockage of the guide plate 86, thereby blocking the plastic particles and preventing the plastic particles from affecting the production quality through the diversion column 82. As the screw 77 rotates, it drives the stirring rod 88 to rotate. As the stirring rod 88 rotates, it drives the stirring plate 811 to rotate through the mounting plate 810. Then, the stirring plate 811 reciprocates between the diversion holes 83 through the sliding groove 89, thereby dredging the diversion holes 83, automatically cleaning the diversion holes 83 during the production process, preventing the diversion holes 83 from being blocked and reducing the production efficiency, and at the same time preventing the blockage of the diversion holes 83 from increasing the melt pressure in the flow-reducing pipe 81 and reducing the product quality.

[0029] Third Embodiment: As Figures 1 to 8 shown, three filter holes 812 are penetrated and opened on the outer surface of the side of the flow-reducing pipe 81 away from the delivery pipe 4. The filter holes 812 are arranged at fixed intervals around the central axis of the flow-reducing pipe 81. A filter ring 813 is provided outside the filter holes 812. The inner surface of the filter ring 813 is fixedly connected to the outer surface of the flow-reducing pipe 81. A gap is reserved between the side of the filter ring 813 away from the delivery pipe 4 and the flow-reducing pipe 81.

[0030] The bottom outer surface of the filter ring 813 is provided with discharge grooves 814 running through it. A sealing ring 815 is slidably sleeved on the outer surface of the filter ring 813. The outer surface of the sealing ring 815 is provided with offset grooves 816 running through it. The offset grooves 816 and the discharge grooves 814 are initially set in an offset state. A polymerization ring 817 is fixedly connected to the outer surface of the filter ring 813 on the side away from the conveying pipe 4. The polymerization ring 817 communicates with the die head 6.

[0031] During operation, when plastic particles accumulate between adjacent guide plates 86, they will follow part of the melt through the filter holes 812 on the flow-reducing pipe 81 and enter the filter ring 813. That is, finally, the filter ring 813 is filled with a mixture of melt and plastic particles. The melt continues to enter the polymerization ring 817 through the gap between the filter ring 813 and the flow-reducing pipe 81, and finally mixes with the melt passing through the flow-dividing column 82 and is conveyed into the die head 6 for film blowing forming. The plastic particles are blocked in the filter ring 813. After production is completed, the sealing ring 815 is rotated so that the offset grooves 816 on the sealing ring 815 communicate with the discharge grooves 814 on the filter ring 813, and the plastic particles in the filter ring 813 are discharged, facilitating the automatic blocking and collection of plastic particles for the next time. By providing the filter ring 813 and the sealing ring 815, it is possible to automatically block and collect plastic particles during the production process, preventing plastic particles from entering the die head 6 with the melt and affecting the product quality. At the same time, by providing the discharge grooves 814 and the offset grooves 816, it is possible to uniformly recycle the plastic particles after production is completed. This can not only improve the continuity of production, but also remelt and utilize the recycled plastic particles, greatly reducing the waste generation rate and the production cost of the enterprise.
