[0002] The main reason for modifying plastic granules is to significantly improve their mechanical properties, processing performance, and durability to meet specific application requirements. The modification process of plastic granules includes raw material preparation, melt mixing, extrusion drying, shearing and crushing.

[0003] During the melt-blending process of plastic granules, various processing aids such as stabilizers, plasticizers, lubricants, calcium carbonate, and pigments need to be added as required. Currently, the addition of processing aids is mostly done manually. Due to the height of the large-volume blending equipment, the top feed inlet is high off the ground. Operators must climb ladders to the top feed inlet of the blending equipment before adding the processing aids, which is inconvenient. In addition, since the melt-blending process requires multiple batches and there are multiple blending machines, operators must frequently climb ladders and add materials sequentially, which is both time-consuming and labor-intensive, resulting in low work efficiency and requiring further improvement.

[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0021] like Figures 1-2 As shown, a feeding module for producing modified plastic granules includes a chamber and a valve body that cooperate with each other. The chamber includes two side plates 1 arranged symmetrically on the left and right, a back plate 6 vertically fixed between the two side plates 1, and a door located between the two side plates 1 and in front of the back plate 6. The door, the back plate 6 and the two side plates 1 form a material chamber 13.

[0022] The valve body includes a base 3 fixed between two side plates 1 and located above the material hopper 13, a top plate 5 horizontally located above the base 3, multiple columns 4 fixed between the top plate 5 and the base 3, a lifting rod 8 vertically inserted in the base 3, a lifting beam 10 located between the top plate 5 and the base 3, and a valve block 9 fixed at the lower end of the lifting rod 8 and located inside the material hopper 13. The upper end of the lifting rod 8 is fixed on the lifting beam 10.

[0023] The valve body also includes two lifting cylinders 11 symmetrically arranged on the left and right sides of the cabin. The fixed ends of the two lifting cylinders 11 are rotatably connected to the outer walls of the two side plates 1, and the telescopic ends of the two lifting cylinders 11 are both arranged facing upward and rotatably connected to the two ends of the lifting beam 10.

[0024] The hatch includes a baffle 7 vertically fixed between two side plates 1, a support block 2 fixed on the upper side of the baffle 7, and a door panel 12 rotatably connected between the two side plates 1 and located above the support block 2. The distance between the rear outer wall of the door panel 12 and the front outer wall of the back plate 6 is greater than the distance between the rear outer wall of the baffle 7 and the front outer wall of the back plate 6.

[0025] A first guide slope 21 with a higher front and lower back is formed on the side of the support block 2 facing the back plate 6. An arc groove 22 is formed at the upper front corner of the support block 2. Correspondingly, a guide cylinder 121 is formed on the front edge of the root of the door panel 12, which is laterally distributed and concentrically arranged with the arc groove 22. The outer peripheral surface of the guide cylinder 121 slides against the arc inner wall of the arc groove 22. The left and right ends of the guide cylinder 121 are rotatably connected to the two side plates 1 respectively.

[0026] The front and rear outer walls of the valve block 9 are slidably attached to the rear outer wall of the baffle 7 and the front outer wall of the back plate 6, respectively. The left and right outer walls of the valve block 9 are slidably attached to the inner walls of the two side plates 1, respectively. A second guide slope 91 with a front lower and rear higher setting is formed on the top front edge of the valve block 9.

[0027] A limiting mechanism is also provided in front of the door panel 12. The limiting mechanism includes a cover plate 14 that is horizontally fixed between the two side panels 1 and located above the door panel 12, a backing plate 16 that is inclinedly fixed between the two side panels 1 and located below the cover plate 14 and in front of the door panel 12, and a support plate 15 that is vertically fixed between the two side panels 1 and located below the backing plate 16. The backing plate 16 is set with the front higher than the back.

[0028] Each of the two side panels 1 has a symmetrically distributed arc-shaped groove 101 on its inner wall. Correspondingly, each of the left and right sides of the end of the door panel 12 has a symmetrically distributed protrusion 122, which are respectively movably embedded in the two arc-shaped grooves 101.

[0029] A handle 17 is also fixed to the front end of the door panel 12.

[0030] On the first guide slope 21, there are also a number of inclined diversion ridges 23 arranged at equal intervals from left to right in the direction of the back plate 6. Each diversion ridge 23 is arranged with the front higher than the back. The rear end of each diversion ridge 23 is formed with a vertically arranged flat surface 24 that is flush with the rear outer wall of the baffle 7 or located in front of the rear outer wall of the baffle 7 to avoid the rear end of the diversion ridge 23 from obstructing the rise and fall of the valve block 9.

[0031] The bottom of the valve block 9 also has an arc-shaped protrusion 92.

[0032] Two vertically distributed limiting rods 18 are also interspersed in the lifting beam 10, with the upper and lower ends of each limiting rod 18 fixed to the top plate 5 and the base 3, respectively.

[0033] Working principle:

[0034] Hold the handle 17 and pull it forward to swing the end of the door panel 12 forward until the front outer wall of the door panel 12 abuts against the back plate 16. A feed inlet is formed between the door panel 12, the cover plate 14 and the two side plates 1. Then, the plastic granules are poured into the rear outer wall of the door panel 12 through the feed inlet and then enter the material chamber 13 along the rear outer wall of the door panel 12.

[0035] Before this, the telescopic ends of the two lifting cylinders 11 in the valve body need to be retracted inward to drive the valve block 9 downward with the help of the lifting beam 10 and the lifting rod 8, so that the valve block 9 moves between the baffle 7 and the back plate 16. At this time, the front and rear outer walls of the valve block 9 are respectively attached to the rear outer wall of the baffle 7 and the front outer wall of the back plate 6, and the left and right outer walls of the valve block 9 are respectively attached to the inner walls of the two side plates 1. The bottom of the material chamber 13 is in a closed state, so the plastic particles entering the material chamber 13 will not fall downward.

[0036] Next, push the end of the door panel 12 backward to make the plastic particles concentrate in the material chamber 13, at which point the feed inlet disappears; then move the present invention above the feed inlet of the equipment, and simultaneously drive the extension ends of the two lifting cylinders 11 in the valve body to extend outward to drive the valve block 9 upward in the same way. When the bottom of the valve block 9 is higher than the baffle 7, a gap appears between the rear end of the first guide slope 21 and the front outer wall of the valve block 9. The plastic particles in the material chamber 13 will be discharged outward through the gap and enter the feed inlet of the equipment to achieve feeding; if the valve block 9 continues to move upward, the width of the gap gradually increases. When the bottom of the valve block 9 is higher than the front end of the first guide slope 21, the flow rate of plastic particles discharged through the gap reaches the maximum.

[0037] The second guide slope 91 on the valve block 9 causes the plastic particles in the material chamber 13 to move toward the first guide slope 21, thereby preventing the plastic particles from accumulating on the top of the valve block 9; and a diversion channel is formed between any two adjacent diversion protrusions 23. The plastic particles on the first guide slope 21 will automatically enter each diversion channel by their own gravity and flow along each diversion channel toward the discharge gap, thereby making the feeding uniform and stable.

[0038] This invention can automatically add processing aids without manual operation. Even if the top feed inlet of the mixing equipment is high off the ground, the invention can be quickly and accurately moved to the top feed inlet of the mixing equipment and automatically added with the help of a robotic arm. This eliminates the need for operators to frequently climb ladders, making operation easier. In addition, it saves time and effort and improves work efficiency.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
