DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0029] Embodiment 1

[0030] Please refer to Figures 1-6, the present invention provides a technical solution: a feeding mechanism, including: a feeding pipe 1, a rotating cylinder 4, and a strip-shaped partition 7.

[0031] Specifically, the feeding pipe 1 is horizontally arranged, and a strip-shaped connecting frame 2 connected to its inner cavity is fixedly connected to the lower end of the outer side wall. The lower end of the strip-shaped connecting frame 2 is communicated with a hollow cylinder 3. A strip-shaped discharging frame 8 is arranged at the lower end of the outer side wall of the hollow cylinder 3. The molten plastic in the inner cavity of the feeding pipe 1 enters the inner cavity of the hollow cylinder 3 after being guided by the strip-shaped connecting frame 2.

[0032] Secondly, the rotating cylinder 4 is rotatably installed in the inner cavity of the hollow cylinder 3 and is adapted to it. A plurality of strip-shaped grooves 5 distributed in an annular array are arranged on the outer side wall of the rotating cylinder 4. After the molten plastic enters the inner cavity of the hollow cylinder 3, it can be filled in the inner cavity of the strip-shaped grooves 5. The number of the strip-shaped grooves 5 is set to be an even number. A communication small hole 6 is penetrated through the bottom of the strip-shaped groove 5. When a strip-shaped groove 5 (for the convenience of distinction, it is called strip-shaped groove 5 one) is located above the inner cavity of the hollow cylinder 3 and is filled with molten plastic, strip-shaped groove 5 one rotates to the lower end opening of the hollow cylinder 3, and the strip-shaped groove 5 (for the convenience of distinction, it is called strip-shaped groove 5 two) at the corresponding position of strip-shaped groove 5 one rotates to above the inner cavity of the hollow cylinder 3 and is filled with molten plastic. Due to the communication effect of the communication small hole 6, the gas in the inner cavity of strip-shaped groove 5 two is compressed. At this time, the molten plastic in the inner cavity of strip-shaped groove 5 one can be discharged from the lower end opening of the hollow cylinder 3 in the dual action of air pressure and its own gravity, and the air pressure in the inner cavity of strip-shaped groove 5 one returns to normal. When strip-shaped groove 5 two rotates to the lower part of the inner cavity of the hollow cylinder 3, the same steps are repeated again, and the molten plastic can be gradually discharged.

[0033] Furthermore, the strip-shaped partition 7 is slidably installed in the inner cavity of the strip-shaped groove 5 and is adapted to it. The strip-shaped partition 7 is provided to prevent the molten plastic from entering the inner cavity of the communication small hole 6, and the strip-shaped partition 7 can slide along the radial direction of the rotating cylinder 4. When the strip-shaped partition 7 slides towards the bottom of the strip-shaped groove 5, the air in the inner cavity of the communication small hole 6 can be quickly compressed.

[0034] Embodiment Two

[0035] On the basis of Embodiment One, in order to improve the sealing performance between the strip-shaped partition 7 and the inner wall of the strip-shaped groove 5, a plurality of strip-shaped partitions 7 are provided in this application. The plurality of strip-shaped partitions 7 respectively correspond to the plurality of strip-shaped grooves 5 one by one. The strip-shaped partition 7 is in a "C" shape with an upward opening to prevent the strip-shaped partition 7 from tilting in the horizontal direction. A sealing layer 14 is bonded to the outer side wall of the strip-shaped partition 7 to improve the sealing performance with the inner wall of the strip-shaped groove 5, prevent the molten plastic from entering the inner cavity of the communication small hole 6, and avoid the leakage of the compressed gas in the inner cavity of the communication small hole 6.

[0036] Embodiment Three

[0037] On the basis of the second embodiment, in order to prevent the strip-shaped partition 7 from separating from the inner cavity of the strip-shaped groove 5, the present application further has limiting baffles 13 fixedly connected to both ends of the strip-shaped partition 7, and stoppers corresponding to the limiting baffles 13 are provided at both ends of the opening of the strip-shaped groove 5. When the strip-shaped partition 7 slides a certain distance in the direction away from the bottom of the strip-shaped groove 5, the strip-shaped partition 7 can push the molten plastic out of the inner cavity of the strip-shaped groove 5. At the same time, when the limiting baffle 13 abuts against the stopper, it can prevent the strip-shaped partition 7 from separating from the inner cavity of the strip-shaped groove 5.

[0038] Embodiment Four

[0039] On the basis of the third embodiment, in order to describe in detail the number and arrangement of the communication small holes 6, multiple communication small holes 6 are provided at the bottom of each strip-shaped groove 5 of the present application, and the multiple communication small holes 6 are equidistantly distributed along the length direction of the strip-shaped groove 5. The communication small holes 6 in the bottom of the strip-shaped grooves 5 at opposite positions are interconnected, and the communication small holes 6 in the bottom of the strip-shaped grooves 5 at adjacent positions are staggered and not interconnected. Therefore, only the gas between the two strip-shaped grooves 5 at opposite positions is interconnected, ensuring that when the strip-shaped groove 5 above the inner cavity of the hollow cylinder 3 is filled with molten plastic, the strip-shaped groove 5 below the inner cavity of the hollow cylinder 3 can simultaneously discharge the molten plastic in its own inner cavity.

[0040] Embodiment Five

[0041] On the basis of the fourth embodiment, in order to adjust the range of the discharged molten plastic, the present application further has an adjusting sealing plate 9 attached and covered on the outside of the lower opening of the strip-shaped discharging frame 8. A sealing gasket is bonded to the upper surface of the adjusting sealing plate 9. An edge boss 10 is fixedly connected to the edge of the lower opening of the strip-shaped discharging frame 8. The edge of the adjusting sealing plate 9 is folded and slidably connected to the edge boss 10. By sliding the adjusting sealing plate 9 along its own length direction, the length of the opening end of the strip-shaped discharging frame 8 can be adjusted to adjust the range of the discharged molten plastic.

[0042] Embodiment Six

[0043] On the basis of the fifth embodiment, in order to drive the sliding of the adjusting sealing plate 9, the present application further has a connecting plate 11 fixedly connected to one end of the adjusting sealing plate 9. An adjusting air cylinder 12 is fixedly connected to the side surface of the connecting plate 11. The adjusting air cylinder 12 is fixedly connected to one end of the hollow cylinder 3. When the adjusting air cylinder 12 works, it is used to drive the adjusting sealing plate 9 to slide.

[0044] Embodiment Seven

[0045] On the basis of Embodiment VI, in order to install and connect the rotating cylinder 4, the present application further has rotating shafts 15 fixedly connected to the middle parts of both end faces of the rotating cylinder 4. One rotating shaft 15 is rotatably connected to the end of the hollow cylinder 3. One end of the hollow cylinder 3 is provided with an opening, and a cover 16 is arranged at the opening. The cover 16 is detachable from the hollow cylinder 3 and is used for installing and connecting the rotating cylinder 4.

[0046] Embodiment VIII

[0047] On the basis of Embodiment VII, in order to maintain the stable connection between the cover 16 and the hollow cylinder 3, the cover 16 of the present application is rotationally connected to the open end of the hollow cylinder 3 by threads. The other rotating shaft 15 is movably penetrated through the middle of the cover 16. A driving motor 17 is fixedly connected to the surface of the cover 16. The output shaft of the driving motor 17 is fixedly connected to the other rotating shaft 15. When the driving motor 17 works, it drives the rotating cylinder 4 to rotate. When the rotating cylinder 4 rotates, the driving motor 17 receives a reverse torsional force, and the direction of this torsional force is the same as the direction in which the cover 16 is tightened. Therefore, the cover 16 can maintain a stable connection with the hollow cylinder 3 without loosening.

[0048] Embodiment IX

[0049] On the basis of Embodiment VIII, in order to ensure that the inner cavity of the strip-shaped groove 5 can be evenly filled with molten plastic, the present application further has a feeding interface 18 arranged at one end of the feeding pipe 1. The end of the feeding interface 18 is communicated with a conveying pipe 19, which is used for conveying molten plastic into the inner cavity of the feeding pipe 1. A plurality of guiding partition plates 21 evenly distributed at equal intervals are fixedly connected to the inner cavity of the strip-shaped connecting frame 2, and the guiding partition plates 21 are inclined, which is used for evenly feeding the molten plastic in the inner cavity of the feeding pipe 1 into the inner cavity of the hollow cylinder 3 to ensure that the inner cavity of the strip-shaped groove 5 can be evenly filled with molten plastic.

[0050] The present invention also discloses a hot-melt plastic drainage plate production device, including the above-mentioned feeding mechanism.

[0051] During actual use, molten plastic is conveyed into the inner cavity of the feeding pipe 1 through the conveying pipe 19. The molten plastic enters the inner cavity of the hollow cylinder 3 after being guided by the strip-shaped connecting frame 2, and is filled in the inner cavity of the strip-shaped groove 5 located above the inner cavity of the hollow cylinder 3 and corresponding to the upper end opening of the hollow cylinder 3. At this time, the strip-shaped partition plate 7 in the inner cavity of the strip-shaped groove 5 moves to fit with the bottom of the strip-shaped groove 5. When the rotating cylinder 4 rotates, the strip-shaped groove 5 rotates and transfers the molten plastic to the lower part of the inner cavity of the hollow cylinder 3. When this strip-shaped groove 5 corresponds exactly to the lower end opening of the hollow cylinder 3, the inner cavity of another strip-shaped groove 5 corresponding exactly to the upper end opening of the hollow cylinder 3 is filled with molten plastic. At this time, the strip-shaped partition plate 7 moves and compresses the gas in the inner cavity of the communication small hole 6. The molten plastic in the inner cavity of the strip-shaped groove 5 corresponding to the lower end opening of the hollow cylinder 3 can be discharged from the inner cavity of this strip-shaped groove 5 in a timely manner under the dual action of air pressure and its own gravity, and falls down under the guidance of the strip-shaped discharging frame 8.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
