[0002] In the production of plastic products, screw kneaders are used to extrude and shape them.
[0003] Existing screw kneaders have filters installed in their storage pipes to remove metals from the fluid and improve the quality of the base product. However, the filters are fixed inside the pipes, and the viscous fluid, which is heated and melted, is difficult to pass through, causing inconvenience for product discharge. Furthermore, the metals in the fluid, due to their contact with the fluid, also become highly viscous, causing them to adhere to the filters, further increasing the difficulty and speed of fluid passage. This affects the product discharge speed and makes the discharge operation inconvenient.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0027] The present invention will be further described below with reference to the embodiments.
[0028] Example 1: Please refer to the accompanying drawings in the instruction manual. Figure 1 - Figure 5A screw extrusion kneader for easy discharge includes a screw kneader body 1; a mixing chamber 2 fixedly installed on the screw kneader body 1; a feed pipe 3 fixedly installed on the front wall of the mixing chamber 2, the feed pipe 3 having a screw rod inside; a filter mechanism 4 installed on the feed pipe 3; a screening mechanism 5 installed on the mixing chamber 2; and a crushing mechanism 6 installed on the screening mechanism 5. The filter mechanism 4 includes a filter pipe 41 sealed to the outer wall of the feed pipe 3; and a filter rod fixedly installed on the filter pipe 41. A motor 42 is mounted on the bottom wall, with its output end extending into the interior of the filter tube 41; a discharge pipe 44 is sealed and connected to the outer wall of the filter tube 41; a filter cylinder 43 is fixedly installed at the output end of the motor 42 and located inside the filter tube 41, with filter holes on its outer wall; a second feed pipe 45 is sealed and connected to the outer wall of the first feed pipe 3 and located inside the filter tube 41, with the interiors of the second feed pipe 45 and the first feed pipe 3 communicating with each other, and the filter cylinder 43 and the second feed pipe 45 are arranged together.
[0029] In practical use, the heated and melted product enters the inside of the conveying pipe 45 through the inside of the first conveying pipe 3, and then flows into the inside of the filter cylinder 43 through the inside of the second conveying pipe 45. It then flows into the inside of the filter pipe 41 through the filter holes on the filter cylinder 43, and finally cools and is discharged through the discharge pipe 44. During discharge, the first motor 42 can be turned on, so that the output end of the first motor 42 drives the filter cylinder 43 to rotate. The rotation of the filter cylinder 43 generates centrifugal force and throws the product inside the filter cylinder 43 through the filter holes, which facilitates the discharge of the product and increases the discharge speed.
[0030] Example 2: Based on Example 1, please refer to the accompanying drawings in the specification. Figure 1 - Figure 5 The screening mechanism 5 includes a screening box 51 fixedly installed on the top wall of the mixing box 2; a second motor 52 fixedly installed on the top of the screening box 51, the output end of the second motor 52 being rotatably connected to the top of the screening box 51, and the output end of the second motor 52 extending into the interior of the screening box 51; a screening cylinder 53 fixedly installed on the output end of the second motor 52, the outer wall of the screening cylinder 53 having screening holes evenly distributed, the screening cylinder 53 being located inside the screening box 51, the upper side wall of the screening cylinder 53 and the top wall of the cavity of the screening box 51 being close to each other; and a discharge pipe 54 sealed to the bottom of the screening box 51, the end of the discharge pipe 54 away from the screening box 51 being sealed to the top wall of the mixing box 2.
[0031] The crushing mechanism 6 includes two sets of conveying pipes 67 sealed to the top of the screening box 51; a crushing box 61 fixedly installed on the outer wall of the two sets of conveying pipes 67; a feed hopper 66 fixedly installed on the top wall of the crushing box 61; and two sets of crushing rollers 62 rotatably installed inside the crushing box 61.
[0032] The crushing mechanism 6 also includes drive shafts 63 fixedly installed on the front side wall of two sets of crushing rollers 62. Both sets of drive shafts 63 are rotatably connected to the front side wall of the crushing box 61, and the outer walls of both sets of drive shafts 63 extend to the outside of the crushing box 61. Drive gears 64 are fixedly installed on the outer walls of the two sets of drive shafts 63, and the two sets of drive gears 64 are meshed together. A motor 65 is fixedly installed on the rear side wall of the crushing box 61, and the output end of the motor 65 is fixedly connected to the right drive shaft 63.
[0033] The filter holes on the filter cylinder 43 correspond to the interior of the discharge pipe 44, and the bottom wall of the filter pipe 41 cavity is an inclined surface that rises from front to back.
[0034] The filter cartridge 43 is detachably mounted on the lower side wall of the conveying pipe 45, and the bottom wall of the screening box 51 is conical with a larger top and a smaller bottom.
[0035] In practical use, plastic granules are first poured into the crushing chamber 61 through the feed funnel 66. During this process, the plastic granules will first fall onto the outer walls of the two sets of crushing rollers 62. The motor 65 is started, causing the right crushing roller 62 to rotate (the right crushing roller 62 rotates counterclockwise when viewed from the front). With the cooperation of the two sets of drive shafts 63 and drive gears 64, the left crushing roller 62 begins to rotate synchronously in the opposite direction. The two sets of crushing rollers 62 crush the plastic granules, while the metal particles are crushed into a flat shape and discharged into the screening cylinder 53 through the conveying pipe 67 along with the crushed plastic granules. When motor 52 is turned on, the output end of motor 52 drives the screening cylinder 53 to rotate. The rotation of the screening cylinder 53 can discharge the crushed plastic through the screening holes into the interior of the screening box 51, while the metal sheet will remain inside the screening cylinder 53. The crushed plastic will be discharged into the interior of the mixing box 2 through the discharge pipe 54 for melting and forming. This crushing and filtering method can reduce the amount of metal products entering, reduce the risk of clogging of the filter cylinder 43, and the crushed plastic is easier to melt, which can shorten the melting time, improve efficiency, and reduce the risk of damage to internal components such as the spiral rod caused by metal.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
