DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 10 As shown, a quantitative feeding device for plastic product production includes: a storage hopper 1, a side plate 5 and a slide seat 9,

[0035] The bottom end of the storage hopper 1 is fixedly connected to a feeding pipe 2, and a feeding port 13 is provided at the top of the feeding pipe 2. A servo motor 12 is fixedly connected to the side end of the feeding pipe 2. The feeding port 13 is respectively communicated with the storage hopper 1 and the inside of the feeding pipe 2. A rotating shaft 14 is fixedly connected to the side end of the servo motor 12, and a spiral blade 15 is fixedly connected to the outer wall of the rotating shaft 14. The side plate 5 is abutted and connected to the storage hopper 1. The slide 9 is arranged at the side end of the feeding pipe 2, and a water sprayer 8 is fixedly connected to the side end of the slide 9. The slide 9 is sleeved and connected to the guide rail assembly, and a driver 11 for driving the slide 9 to slide is fixedly connected to the side end of the guide rail assembly. When the quantitative feeding equipment changes the raw materials of plastic products of different colors, the staff cleans the equipment and now pours water from the storage hopper 1. The water penetrates The plastic raw materials are discharged from the outlet end of the conveying pipe 2 through the feed inlet 13, and then the staff removes the side plate 5 from the conveying pipe 2. At this time, the rotating shaft 14 and the spiral blade 15 in the side plate 5 leak out, and then the driver 11 is operated. The driver 11 drives the slide 9 to reciprocate on the guide rail assembly, and the slide 9 reciprocates along the length direction of the conveying pipe 2 with the water sprayer 8. The water sprayer 8 sprays the cleaning water on the rotating shaft 14 and the spiral blade 15. The cleaning water washes the plastic raw materials from the rotating shaft 14 and the spiral blade 15. The plastic raw materials will slide along the inner wall of the storage hopper 1 to prevent the plastic raw materials from adhering to the inner wall of the conveying pipe 2, resulting in insufficient cleaning of the equipment.

[0036] The side panel 5 is detachable on the feed pipe 2. When the side panel 5 is removed and the rotating shaft 14 and the spiral blades 15 leak out of the feed pipe 2, the servo motor 12 starts to operate, and the servo motor 12 drives the rotating shaft 14 to rotate, and the rotating shaft 14 drives the spiral blades 15 to rotate. The rotation of the spiral blades 15 can throw out the surface water and plastic product raw materials, further improving the effect of cleaning the plastic product raw materials of the equipment.

[0037] In some specific embodiments, the guide rail assembly includes: a connecting plate 6 and a guide rail 7, wherein the guide rail 7 is provided with two groups and both ends are fixedly connected to the connecting plate 6 respectively, the side end of the connecting plate 6 is fixedly connected to the conveying pipe 2, and the slide 9 is sleeved and connected to the guide rail 7. When the driver 11 drives the slide 9 to slide, the slide 9 moves along the guide rail 7, and the slide 9 moves with the sprinkler 8. During the movement of the sprinkler 8, the water sprayed by the sprinkler 8 sweeps the surface of the rotating shaft 14 and the spiral blade 15, and the swept water knocks down the plastic product raw materials, wherein the guide rail 7 is fixed to the side end of the storage hopper 1 through the connecting plate 6, and the guide rail 7 can support the slide 9 and the sprinkler 8 at the side end of the storage hopper 1.

[0038] In some specific embodiments, the side end of the slide 9 is fixedly connected to the connecting pipe head 10 and is interconnected with the connecting pipe head 10. In order for the sprinkler 8 to continuously spray water to clean the plastic product raw materials, the water pipe of the prior art is connected to the connecting pipe head 10, and the water is passed to the connecting pipe head 10 through the water pipe, and then the water passes through the slide 9 to continuously supply water to the sprinkler 8.

[0039] In some specific implementation schemes, mounting seats 3 are fixedly connected to both sides of the bottom end of the feed pipe 2, and mounting holes 4 are formed through the mounting seats 3. In order to prevent the side panels 5 from affecting the installation of the feed pipe 2 when being removed, the mounting seats 3 fixed at the bottom end of the feed pipe 2 provide support for the feed pipe 2. Bolts are passed through the mounting holes 4 and installed on the workbench of the prior art, thereby achieving the effect of fixing the feed pipe 2 by the mounting seats 3 and avoiding contact between the side panels 5 and the workbench.

[0040] In some specific implementation schemes, the side end of the side plate 5 is fixedly connected to the limit plate 20, and the side plate 5 is fixedly connected to two sets of positioning tubes 16 at one end close to the servo motor 12. The side end of the feed pipe 2 is provided with a limit groove 21, and the side end of the feed pipe 2 is provided with a positioning hole 17. The limit plate 20 is abutted against the inner wall of the limit groove 21, and the positioning tube 16 is abutted against the inner wall of the positioning hole 17. When the plastic product raw materials on the equipment are cleaned, the staff installs the side plate 5 on the feed pipe 2, and fixes the side plate 5. The fixed limit plate 20 is inserted into the limit groove 21, and then the side panel 5 is moved in the direction of the servo motor 12, and the positioning tube 16 fixed at the side end of the side panel 5 is inserted into the positioning hole 17. The limit plate 20 and the inner wall of the limit groove 21 abut against each other to provide a limiting support for the side panel 5. At the same time, the side panel 5 slides along the inner wall of the limit groove 21 through the limit plate 20, thereby providing a guide for the positioning tube 16 to be inserted into the positioning hole 17, facilitating the operation of inserting the positioning tube 16 into the positioning hole 17.

[0041] In some specific implementation schemes, the side end of the positioning tube 16 is abutted against the inner wall of the positioning hole 17, and the inner wall of the positioning tube 16 is threadedly connected with a positioning bolt 18. A positioning threaded hole 19 is opened at the end of the feed pipe 2 close to the servo motor 12. The axis of the positioning threaded hole 19 coincides with the axis of the positioning hole 17, and the inner diameter of the positioning threaded hole 19 is smaller than the inner diameter of the positioning hole 17. The positioning threaded hole 19 is threadedly connected with the positioning bolt 18. When the positioning tube 16 is inserted into the positioning hole 17, the staff rotates the positioning bolt 18 to be threadedly connected in the positioning threaded hole 19 and the positioning tube 16. The positioning bolt 18 is threadedly connected with the positioning threaded hole 19 and the inner wall of the positioning tube 16, thereby fixing the positioning tube 16 in the positioning hole 17, thereby limiting and fixing the side plate 5 to prevent the side plate 5 from loosening.

[0042] In some specific embodiments, a fixing groove 24 is opened at the side end of the rotating shaft 14, and a stirring component is connected to the inner wall of the fixing groove 24. The stirring component is at the outlet end of the feed pipe 2. When the discharge amount of the plastic product raw material increases, the rotation speed of the rotating shaft 14 becomes faster. At this time, the plastic product raw material is prone to blockage at the outlet end of the feed pipe 2, thereby affecting the quantitative feeding of the plastic product raw material. In order to avoid the blockage of the plastic product raw material at the outlet end of the feed pipe 2, when the rotating shaft 14 rotates rapidly, the rotating shaft 14 rotates with the stirring component, and the stirring component stirs the plastic product raw material at the outlet end of the feed pipe 2, thereby avoiding blockage of the plastic product raw material.

[0043] In some specific embodiments, the stirring assembly includes: a fixed seat 25, a connecting column 26 and a stirring column 27. The fixed seat 25 is connected to the inner wall of the fixed groove 24. The fixed seat 25 passes through the interior of the rotating shaft 14 to open a fixed threaded hole 22. The inner wall of the fixed threaded hole 22 is threadedly connected with a fixing bolt 23. The stirring column 27 has two groups located on both sides of the fixed seat 25. The connecting column 26 is cylindrical and its two ends are fixedly connected to the fixed seat 25 and the stirring column 27 respectively. When the stirring assembly rotates with the rotating shaft 14, the rotating shaft 14 passes through the inner wall of the fixed groove 24. The wall abuts against the fixing seat 25 to drive the fixing seat 25 to rotate, and the fixing seat 25 drives the stirring column 27 to rotate through the connecting column 26. The stirring column 27 stirs the plastic product raw materials at the outlet end of the feeding pipe 2. When the equipment cleans the remaining plastic product raw materials, the staff rotates the fixing bolt 23 to release the threaded connection between the fixing bolt 23 and the fixing threaded hole 22, and then removes the fixing seat 25 from the fixing groove 24, wherein the fixing bolt 23 fixes the fixing seat 25 on the rotating shaft 14 through the threaded connection with the fixing threaded hole 22.

[0044] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0045] When the quantitative feeding equipment changes the plastic product raw materials of different colors, the staff cleans the equipment and removes the side plate 5 from the feeding pipe 2. At this time, the rotating shaft 14 and the spiral blade 15 in the side plate 5 leak out, and then the driver 11 is operated. The driver 11 drives the slide 9 to reciprocate on the guide rail assembly, and the slide 9 carries the sprinkler 8 to reciprocate along the length direction of the feeding pipe 2. During the movement of the sprinkler 8, the water sprayed by the sprinkler 8 sweeps the surface of the rotating shaft 14 and the spiral blade 15, and the swept water knocks down the plastic product raw materials. The cleaning water washes the plastic product raw materials from the rotating shaft 14 and the spiral blade 15, and the plastic product raw materials slide down along the inner wall of the storage hopper 1, wherein the water pipe of the prior art is connected to the connecting pipe head 10, and the water is passed to the connecting pipe head 10 through the water pipe, and then the water passes through the slide 9 to continuously supply water to the sprinkler 8;

[0046] The side plate 5 is detachable on the feeding pipe 2. When the side plate 5 is removed and the rotating shaft 14 and the spiral blade 15 leak out of the feeding pipe 2, the servo motor 12 is operated, the servo motor 12 drives the rotating shaft 14 to rotate, and the rotating shaft 14 drives the spiral blade 15 to rotate. The spiral blade 15 rotates to throw out the surface water flow and the plastic product raw material.

[0047] The side panel 5 is removed, and then the water sprayer 8 cleans the leaked rotating shaft 14 and spiral blades 15, thereby ensuring that the rotating shaft 14 and spiral blades 15 are cleaned more fully. The plastic product raw materials will fall along the inner wall of the feed pipe 2 due to the impact of water, avoiding the phenomenon that the plastic product raw materials adhere to the inner wall of the feed pipe 2 and cause insufficient equipment cleaning. At the same time, the spiral blades 15 can throw out the surface water flow and plastic product raw materials through rotation, further improving the effect of cleaning the plastic product raw materials from the equipment.

[0048] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
