Description

Technical Field

[0001] The utility model belongs to the field of plastic processing machinery, in particular to a masterbatch screening machine for processing new material modified nylon insulation strips. Background Art

[0002] Modified nylon materials are often used to make thermal insulation strips. Such materials are widely used in the construction industry, such as thermal insulation bridge technology in door and window frames to reduce heat transfer and improve energy efficiency. Masterbatch refers to plastic concentrates containing high concentrations of additives. They are added to the base resin to give the final product specific properties.

[0003] The main function of the masterbatch screening machine is to ensure that the masterbatch used to produce thermal insulation strips meets the size and quality requirements, thereby ensuring the performance and consistency of the final product. For example, a masterbatch screening machine disclosed in Chinese patent CN210675904U has a drive assembly and a rotating shaft assembly connected between the housing and the screen assembly. The drive assembly can drive the screen assembly to rotate around the rotating shaft of the rotating shaft assembly, thereby tilting the screen assembly to facilitate the discharge of the masterbatch remaining in the screen. However, the above masterbatch screening machine still has some shortcomings in actual use, as follows:

[0004] Although the above-mentioned masterbatch screening machine describes that the linear drive device can drive the screen assembly to rotate around the rotating shaft, it does not specifically explain how to control the rotation angle and speed. If the control is improper, it may lead to uneven masterbatch screening or low screening efficiency. Utility Model Content

DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example: A new material modified nylon insulation strip processing masterbatch screening machine, such as Figures 1-4 As shown, it includes a base frame 1, a casing 2, a material receiving frame 3, a material blocking group and a screening group. The casing 2 is arranged on the top of the base frame 1. The casing 2 is a hollow frame with the top and the bottom connected. A plurality of rectangular openings are opened on the front side of the casing 2. A plurality of material receiving frames 3 are symmetrically arranged from top to bottom on the front side of the casing 2 to collect the masterbatches of different sizes that have been screened. Each material receiving frame 3 corresponds to the bottom of each rectangular opening. The inside of the casing 2 and the front side are jointly provided with a material blocking group for blocking the discharge of the masterbatch. The casing 2 and the rear side are jointly provided with a screening group for uniformly screening the masterbatch.

[0026] like Figure 1-Figure 3As shown, the material blocking group includes: a rotating plate 4, a torsion spring 5, an electric push rod 6 and a lifting frame 7. Several rotating plates 4 are symmetrically and rotatably arranged on the front side of the casing 2. Each rotating plate 4 corresponds to the rear of each rectangular opening and covers it. A torsion spring 5 is provided between the rotating connection between each side of each rotating plate 4 and the inside of the casing 2 to provide a restoring force when the rotating plate 4 is in the closed state. An electric push rod 6 is provided on the front side of the upper part of the casing 2 to control the up and down movement of the lifting frame 7. A lifting frame 7 is provided on the telescopic end of the electric push rod 6 to control the opening and closing of the rotating plate 4. When the lifting frame 7 is closed, an opening is provided on the lifting frame 7, which is located on the outside of part of the material receiving frame 3. The rear side of the lifting frame 7 is slidably connected to the front side of the casing 2, and the front sides of the rotating plates 4 are in contact with the rear side of the front lifting frame 7. When the rotating plate 4 is in contact with the rear side of the lifting frame 7, the torsion spring 5 is in a tightened state. When the electric push rod 6 drives the lifting frame 7 to slide, the opening of the lifting frame 7 will cover the front side of the rotating plate 4. The closed part of the rear side of the lifting frame 7 no longer contacts the front side of the rotating plate 4, so that the torsion spring 5 is loosened to drive the rotating plate 4 to rotate, so that the rectangular opening of the casing 2 is in an open state.

[0027] like Figure 2-Figure 4 As shown, the screening group includes: an inclined plate 8, a screen plate 9, a lifting plate 10, a return spring 11, a motor 12 and a runner 13. A number of inclined plates 8 are arranged at equal intervals from top to bottom on the front side of the casing 2 to guide the material to flow downward. A rated size of blanking space is left between the rear end of each inclined plate 8 and the inner rear wall of the casing 2. A number of sieve plates 9 are arranged at equal intervals from top to bottom between the two sides of the casing 2. Different levels of sieve plates 9 are used to screen masterbatches of different sizes. A number of inclined plates 8 and a number of sieve plates 9 are staggered, and each sieve plate 9 is located below each inclined plate 8. Each sieve plate 9 is arranged in an inclined shape, and the lowest point of the lower end of each sieve plate 9 is equal to the highest point on the upper end of the receiving frame 3. The higher the point, the denser the screen mesh of the sieve plate 9 is located below. A lifting plate 10 is slidingly provided on the rear side of the casing 2, which drives the sieve plate 9 to move by lifting. The rear sides of each sieve plate 9 are connected to the front side of the lifting plate 10. The upper and lower sides of the rear side of the lifting plate 10 protrude outward, and a convex rod is provided in the upper and middle part of the lifting plate 10. Return springs 11 are symmetrically provided between the two ends of the two protrusions and the rear side of the casing 2 to provide restoring force for the lifting plate 10. A motor 12 is provided in the middle position of the rear side of the casing 2 to drive the runner 13 to rotate. A runner 13 is provided on the output shaft of the motor 12. The runner 13 rotates and contacts with the convex rod on the rear side of the lifting plate 10 to make the lifting plate 10 move up and down.

[0028] like Figure 2 and Figure 5As shown, it also includes a brush frame 14 and a guide rod 15. The inside of the casing 2 is provided with guide rods 15 corresponding to the top of each sieve plate 9 from top to bottom, and the guide rods 15 are in an inclined state, the end close to the sieve plate 9 is the lowest end, and the end connected to the inner side of the casing 2 is the highest end. A brush frame 14 is slidably provided on the outside of each guide rod 15, and the brush rods at the bottom of each brush frame 14 are in sliding contact with the screen of the sieve plate 9 below. The brush frame 14 slides along the guide rods 15 to make it easier to discharge the masterbatch on the sieve plate 9.

[0029] When it is necessary to screen the masterbatch, first place a storage box just below the bottom of the casing 2, and then put the masterbatch into it from the top of the casing 2. At this time, the electric push rod 6 has not been started, so the lifting frame 7 is in the initial position, so that the rotating plate 4 remains closed under the action of the torsion spring 5, preventing the masterbatch from falling directly from the rectangular opening, ensuring that the masterbatch can be evenly distributed and effectively screened. Subsequently, the motor 12 is started to drive the runner 13 to rotate, and the runner 13 contacts the convex rod on the rear side of the lifting plate 10, pushing the lifting plate 10 up and down. The up and down movement of the lifting plate 10 drives the sieve plate 9 connected to it to vibrate. The vibration of the sieve plate 9 prompts the masterbatch to be screened on its surface. Since the sieve plate 9 and the inclined plate 8 are staggered and the sieve plate 9 is located below the inclined plate 8, the masterbatch will slide on the inclined plate 8 and fall onto the sieve plate 9. Under the vibration of the sieve plate 9, smaller masterbatch will pass through the sieve holes and fall onto the inclined plate 8 below and continue to slide down. Until it passes through the next sieve plate 9; larger-sized masterbatches stay on the current sieve plate 9 until they reach the required size. The sieve plate 9 has a smaller aperture as it goes down, which means that the masterbatch size becomes smaller as it falls. Finally, the masterbatch that meets the minimum size requirement will pass through the last sieve plate 9, and the smaller-sized masterbatch will be directly discharged from the bottom of the casing 2. In order to further improve the screening efficiency, as the sieve plate 9 vibrates, the brush frame 14 will also slide up and down along the guide rod 15 to help remove the masterbatch or impurities that may block the sieve holes on the screen, ensuring that the screening process proceeds smoothly. When all the masterbatches have completed the screening process, the operator can start the electric push rod 6 to push the lifting frame 7 upward so that its opening no longer covers the rotating plate 4. At this time, the torsion spring 5 releases energy and the rotating plate 4 rotates to open the rectangular opening. In this way, the masterbatch staying on each sieve plate 9 will fall into the corresponding material receiving frame 3 according to its position, completing the entire screening process.

Any equivalent substitutions made within the principles of the present invention shall be included within the scope of protection of the present invention. Any matters not fully described in the present invention are prior art known to those skilled in the art.
