Description

Technical Field

[0002] At present, the boards and profiles used in people's production and life consume a large amount of wood every year. The amount and growth rate of wood are seriously out of balance. At the same time, waste plastics seriously pollute the environment. Therefore, plastic board products can be produced by utilizing wood powder, polyolefins, masterbatches, etc.

[0003] For example, the plastic sheets, profiles and production methods disclosed in the patent document with publication number CN107383517A mainly use recycled polyolefin granules as the plastic material. The polyolefin recycled granular plastic is blended and granulated in a twin-screw extruder. Maleic anhydride is used to graft PE compatibilizer, which also serves as an interface regulator between polyolefin and inorganic fiber. The semi-finished granular material is colored and mixed with a foaming agent to make imitation wood plastic sheets, and the surface imitation wood effect is made more realistic.

[0004] In the process of feeding granular plastic into the screw extruder, the plastic particles are generally adsorbed into the discharge barrel through an adsorption pipe, and then the plastic particles are fed into the screw extruder through the discharge barrel. In the process of feeding the existing discharge barrel into the extruder, the material is easily blocked at the discharge port, and the discharge port needs to be stopped to clean it, which causes inconvenience to the processing of plastic sheets.

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The embodiment of the utility model provides a plastic plate processing and unloading mechanism, which is used for connecting to a screw extruder and unloading materials into the screw extruder. By setting a transition structure, blockage of plastic particles when entering the screw extruder is prevented.

[0035] The plastic sheet processing and unloading mechanism of this embodiment includes a cylinder 10, a proportional valve 20, a transition frame 30 and a transition cylinder 40. The cylinder 10 is provided with a material cavity 11, and a feed port 12 and a discharge port 13 connected to the material cavity 11. The feed port 12 and the discharge port 13 are respectively located at the two ends of the cylinder 10. The proportional valve 20 is installed at the feed port 12 to control the proportion of material entering the feed port 12; the transition frame 30 is fixed to one end of the cylinder 10 close to the discharge port 13; one end of the transition cylinder 40 is fixed to the transition frame 30 and encloses the discharge port 13, and the other end is used to be connected to the extruder.

[0036] Specifically, the plastic sheet processing and unloading mechanism is provided with a cylinder 10, a proportional valve 20, a transition frame 30 and a transition cylinder 40. The cylinder 10 is provided with a material cavity 11, a feed port 12 and a discharge port 13. The feed port 12 and the discharge port 13 are respectively located at both ends of the cylinder 10. The granular plastic enters the material cavity 11 through the feed port 12 after the adsorption effect of the adsorption setting. The proportional valve 20 is installed at the feed port 12. The amount of material entering the material cavity 11 can be controlled by adjusting the size of the feed port 12. The material in the material cavity 11 passes out through the discharge port 13 and enters the spiral extruder. Machine, since the unloading mechanism is also provided with a transition frame 30 and a transition cylinder 40, the transition frame 30 is fixed to one end of the barrel 10 near the unloading port 13, and the transition cylinder 40 is fixed by the barrel and encloses the unloading port 13, so that the plastic particles discharged from the unloading port 13 can pass through the transition of the transition cylinder 40 and then enter the screw extruder. Since the diameter of the barrel 10 is larger than the diameter of the unloading port 13, after the plastic particles fall into the barrel 10 through the unloading port 13, they can be dispersed inside the barrel 10, effectively avoiding blockage of the plastic particles in the process of entering the screw extruder.

[0037] In one embodiment, the discharge port 13 is provided with a valve plate 131, which is hinged to the cylinder 10 and can be rotated to open or close the discharge port 13. Specifically, the valve plate 131 can rotate under weight, so that the size of the discharge port 13 can be controlled according to the amount of plastic particles.

[0038] In one embodiment, the barrel 10 includes a lower barrel 14, a filter screen 15, and a barrel cover 16. The upper end of the lower barrel 14 is provided with an opening, the filter screen 15 is mounted on the opening of the lower barrel 14, and the barrel cover 16 is detachably provided on the opening of the lower barrel 14. Specifically, the lower barrel 14 and the barrel cover 16 are combined to form the barrel 10 structure. The filter screen 15 is provided through the opening of the lower barrel 14 to filter the plastic particles entering the material chamber 11. The barrel cover 16 is detachably provided on the opening of the lower barrel 14 to facilitate cleaning and replacement of the filter screen 15.

[0039] In this embodiment, in order to facilitate material discharge, the lower end of the lower cylinder 14 is tapered.

[0040] In one embodiment, the opening of the lower cylinder 14 is provided with a mounting groove 111, and the filter screen 15 is mounted in the mounting groove 111. Specifically, the mounting groove 111 can provide a mounting for the filter screen 15 to achieve stability of the filter screen 15.

[0041] In one embodiment, the barrel body 10 further includes a plurality of buckles 17, each buckle 17 being mounted on the lower barrel 14 along its circumference and capable of being rotated to engage the barrel cover 16. Specifically, each buckle 17 secures the barrel cover 16 by engaging the barrel cover 16. To remove the barrel cover 16, the buckle 17 need only be detached from the barrel cover 16.

[0042] In one embodiment, the proportional valve 20 includes a valve body 21, a cylinder 22 and a valve plate 131. The valve body 21 is provided with a valve port 211. The cylinder 22 is fixed to the valve body 21. The valve plate 131 is installed at the driving end of the cylinder 22. The cylinder 22 drives the valve plate 131 to rise and fall, thereby adjusting the opening ratio of the valve port 211, thereby adjusting the amount of granular plastic entering the material chamber 11.

[0043] In one embodiment, the transition frame 30 includes an upper connecting ring 31, a lower connecting ring 32, and a plurality of connecting rods 33. The upper connecting ring 31 is fixed to the barrel 10 and is located around the discharge port 13. The lower connecting ring 32 is opposite the upper connecting ring 31. The ends of each connecting rod 33 are respectively fixed to the upper connecting ring 31 and the lower connecting ring 32. The transition barrel 40 is located between the upper connecting ring 31 and the lower connecting ring 32 and abuts against the upper and lower connecting rings 31 and 32. Specifically, the upper connecting ring 31 and the lower connecting ring 32 limit the upper and lower ends of the transition barrel 40, thereby ensuring the stability of the transition barrel 40.

[0044] In one embodiment, the transition tube 40 is a transparent cylinder 10. Specifically, by setting the transition tube 40 as a transparent cylinder 10, the flow of plastic particles can be easily observed, thereby facilitating the proportional valve 20 to control the amount of granular plastic entering the material chamber 11 to prevent blockage when the plastic particles flow out.

[0045] In one embodiment, the upper connecting ring 31 and the lower connecting ring 32 are both provided with limiting grooves 311 on the opposite sides, and the ends of the transition tube 40 are mounted in the limiting grooves 311. Specifically, the limiting grooves 311 can limit the upper and lower ends of the transition tube 40, thereby achieving stability of the transition tube 40.

[0046] In one embodiment, the transition frame 30 further includes a rubber pad 34, which is mounted in the retaining groove 311 and seals against the end surface of the transition barrel 40. Specifically, the rubber pad 34 seals the gap between the transition barrel 40 and the upper and lower connecting rings 31 and 32, while also protecting the transition barrel 40 from being crushed by the upper and lower connecting rings 31 and 32.

[0047] In one embodiment, a mounting ring 18 is fixed to the lower end of the cylinder 10, and the upper connecting ring 31 is fixed to the mounting ring 18. Specifically, the mounting ring 18 can be used for the upper connecting ring 31 to be installed, thereby achieving stability of the transition frame 30.

[0048] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
