Description

Technical Field

[0001] The utility model relates to the technical field of plastic masterbatch screening, in particular to a plastic masterbatch screening device. Background Art

[0002] With the development of the plastics industry and the advancement of technology, the definition and connotation of masterbatch in plastics processing have been expanded and deepened. It is not limited to small doses of raw materials such as colorants. Masterbatch has become a special material, also known as a special preparation, usually composed of a specific material, a carrier resin and various additives. It is a high-concentration concentrate of specific raw materials uniformly loaded in the resin. It is easy to use in granular form. In the process of processing and molding plastic masterbatch, inorganic fillers and resins are first put into the internal mixer for internal mixing. After meeting the process requirements, the material is discharged into the single screw extruder for granulation, and finally cooled and screened.

[0003] After searching, the Chinese patent with announcement number: CN214521307U discloses a plastic masterbatch screening device, including a screening cylinder, a plurality of parallel vibrating screens, a shaking mechanism and a vibration mechanism, a plurality of annular grooves are opened on the side wall of the screening cylinder, the annular grooves are connected to the arcuate through groove, the tooth pattern portion on one side wall of the vibrating screen protrudes from the arcuate through groove to engage the shaking mechanism, and the arcuate convex portion on the other side wall protrudes from the arcuate through groove to connect the vibration mechanism; the shaking mechanism includes a motor, a notched gear, a gear and a rack, the motor shaft is connected to the notched gear, the notched gear engages the gear and the rack, and the rack engages with the vibrating screen through the tooth pattern portion; the vibration mechanism includes a vibrating rod and an "S"-shaped rotating member, the "S"-shaped rotating member is driven by a servo motor (not shown) to movably abut against the abutment fixed at the upper end of the vibrating rod, so that the knocking block installed at the lower end of the vibrating rod regularly knocks the arcuate convex portion, driving the vibrating screen to vibrate.

[0004] The working principle of the above patent mentions that "starting the motor 6 and the servo motor, the motor 6 drives the notched gear 7 to rotate, so that the gear 8 or the rack 9 moves. Because the notched gear 7 has a clearance meshing with the gear 8 and the rack 9, the notched gear 7 can rotate to realize the reciprocating motion of the rack 9. When the rack 9 reciprocates back and forth, the vibrating screen 2 meshing with the rack 9 also rotates synchronously; the servo motor can drive the "S"-shaped rotating part 11 to rotate, and the rotation of the "S"-shaped rotating part 11 will cause the vibration rod 10 to knock up and down, thereby causing the knocking block 13 to regularly knock the arc-shaped convex part 5, driving the vibrating screen 2 to vibrate." However, the above-mentioned fine screening of plastic masterbatches is achieved through two vibrating screens, but if higher screening particle size requirements are required, and when processing plastic masterbatches with high humidity and viscosity, the screen is prone to blockage of holes and cannot be screened. In view of the above problems, a plastic masterbatch screening device is proposed to solve the above problems. Utility Model Content

The top of the sleeve 3 is fixedly connected with a lower hopper 7, and the left end of the sleeve 3 is fixedly connected with an inner tube 8. When the motor 4 is started, the screw dragon 5 in the sleeve 3 will be driven to rotate and transport the plastic masterbatch flowing into the lower hopper 7 to the position of the inner tube 8 and the pillar 6 and finally to the screen drum 10. The left end of the sleeve 3 is fixedly connected with a spring 9. The design of the spring 9 is to protect the right side of the screen drum 10 and to enable the screen drum 10 to slide left and right.

[0033] An inner cylinder 11 is fixedly connected to the inside of the sieve cylinder 10, and a connecting cylinder 12 is fixedly connected to the right side of the inside of the sieve cylinder 10. A card slot 13 is provided on the upper and lower sides of the connecting cylinder 12. The card slot 13 is designed to fix the positions of the sieve cylinder 10 and the inner cylinder 11, and the inner cylinder 11 and the sieve cylinder 10 can perform multi-layer screening of plastic masterbatch. A circular groove 14 is provided on the right side of the sieve cylinder 10, and a through hole 15 is provided in the middle of the left side of the sieve cylinder 10. A limiting rod 16 is fixedly connected to the top left side of the sieve cylinder 10. In this way, in order to enable the sieve cylinder 10 to be rotated and fixed, the middle part of the cover plate 17 is fixedly connected to the limiting component, and the bottom end of the sleeve 1 is fixedly connected to four supporting legs 30, and the supporting legs 30 support the entire device.

[0034] refer to Figure 2-Figure 4 The limiting assembly includes a centering rod 18, a positioning block 19, a positioning block 20, an adjustment plate 21, a through slot 1 22, a through slot 23 and a threaded rod 24.

The positioning block 19 and the centering rod 18 are fixedly connected to the middle of the positioning block 19, and the right side of the positioning block 20 is fixedly connected to the left end top side of the adjustment plate 21. The positioning block 20 connects the adjustment plate 21 and the cover plate 17, so that the adjustment plate 21 can be rotated at the right side of the cover plate 17 through the connection of the positioning block 19 while being able to rotate an angle. The through slot 1 22 is opened in the middle of the top of the adjustment plate 21, and the through slot 23 is opened in the middle of the adjustment plate 21. This design is to avoid hindering the angular rotation of the adjustment plate 21. The external thread of the threaded rod 24 is connected to the middle of the bottom end of the cover plate 17, and the threaded rod 24 is rotated to extend the bottom of the cover plate 17.

[0035] The outside of the auger 5 is slidably connected to the inner wall of the inner tube 8. In order to maintain the stable transportation of plastic masterbatch by the sleeve 3, the outside of the support 6 is slidably connected to the inner wall of the slot 13. The support 6 slides against the inner wall of the connecting tube 12 and then retracts from the slot 13 to fix the sieve cylinder 10, so that the rotation of the auger 5 can drive the sieve cylinder 10 to rotate. The left end of the spring 9 is in contact with the right end of the sieve cylinder 10. The spring 9 is limited to the left end of the sleeve 3 and the right end of the sieve cylinder 10 to drive the sieve cylinder 10 to slide left and right, thereby increasing the screening capacity of the sieve cylinder 10 and the inner cylinder 11.

[0036] The outer part of the limit rod 16 is movably connected to the inner wall of the through slot 1 22, the outer right side of the centering rod 18 is engaged with the inner wall of the through hole 15, and the right end of the threaded rod 24 is in contact with the left bottom end of the adjustment plate 21, so that the screen drum 10 and the inner drum 11 can be rotated for screening and can slide left and right after being fixed, thereby improving the screening efficiency. Compared with the above documents, by connecting the auger 5 and adjusting the angle of the adjustment plate 21, the screen drum 10 can solve the problem of not being able to achieve higher particle size screening requirements and processing plastic masterbatch with higher humidity and viscosity through centrifugal force.

[0037] refer to Figure 5 The front and rear ends of the left side of the cover plate 17 are fixedly connected with fixed blocks 25, the front and rear sides of the left side of the sleeve box 1 are fixedly connected with fixed point blocks 26, the upper and lower sides of the fixed point blocks 26 are fixedly connected with support rods 27, the outside of the support rod 27 is rotatably connected with a clamping block 28, and the far side of the two clamping blocks 28 is fixedly connected with a spring 29, the outside of the cover plate 17 is engaged with the middle part of the left side of the sleeve box 1, and the clamping blocks 28 on both sides of the sleeve box 1 are rotated around the support rod 27 to squeeze the spring 29 outward to release the engagement of the fixed block 25 on the cover plate 17, so that the user can remove the cover plate 17 and open the opening on the left side of the sleeve box 1.

[0038] The outside of the clamp block 28 is slidably connected to the inner wall of the fixed block 26, and the far side of the two springs 29 is fixedly connected to the upper and lower sides of the inner wall of the fixed block 26. The spring 29 connects the fixed block 26 and the clamp block 28 to increase the clamping force of the clamp block 28, thereby fixing the position of the cover plate 17. The close side of the two clamp blocks 28 is engaged with the outside of the fixed block 25, and the clamp block 28 is engaged with the fixed block 25 to fix the cover plate 17.

[0039] Working principle: Before use, you can first bend the clamping blocks 28 on both sides of the sleeve 1 and rotate them around the support rod 27 to squeeze the spring 29 outward to loosen the engagement of the fixing block 25 on the cover plate 17, so that the user can remove the cover plate 17, open the opening on the left side of the sleeve 1, and take out the fixed screen cylinder 10, inner cylinder 11, and connecting cylinder 12 placed inside. After taking them out, they can be carefully cleaned with clean water. After cleaning, align the circular groove 14 of the screen cylinder 10 with the left end of the sleeve 3 and the inner tube 8, and place it so that the sleeve 3 is inserted into the inside of the connecting cylinder 12. And let the support 6 on the sleeve 3 slide on the inner wall of the connecting tube 12 and engage in the position of the slot 13 so that the sleeve 3 can be rotated and then connected to the screen drum 10 to rotate. When the right side of the screen drum 10 is fixed, the cover plate 17 is reset, and the limit rod 16 on the screen drum 10 is inserted into the through groove 12 of the adjustment plate 21, and the centering rod 18 of the cover plate 17 is inserted into the through hole 15 of the screen drum 10. Finally, the threaded rod 24 is rotated to press against the bottom of the adjustment plate 21 to adjust the angle of the adjustment plate 21, and the plastic masterbatch can be poured into the lower hopper 7 for screening.

[0040] When the plastic masterbatch enters the sleeve 3 through the lower hopper 7, the user can start the motor 4 to drive the sleeve 3 to rotate and transport the plastic masterbatch to the position of the screen drum 10, and then the centrifugal force of the screen drum 10 is thrown through the holes of the inner cylinder 11 of the inner wall of the screen drum 10 for the first layer of screening, and then the holes of the screen drum 10 are screened for the second time, and finally the screened plastic masterbatch will flow out of the hole of the discharge hopper 2 to complete the work. During the rotation of the screen drum 10, since the adjustment plate 21 is in an inclined state, the screen drum 10 limited by the sleeve 3 and the centering rod 18 is connected to the limit rod 16 and driven by the rotating adjustment plate 21 and the elastic force of the spring 9 so as to slide left and right while rotating, thereby accelerating the screening of the plastic masterbatch.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
