[0002] After production, plastic granules are solid granules. These granules need to be bagged for transportation and storage. Current packaging methods typically use a discharging device to fill the bags, such as the discharging cylinder disclosed in Chinese Patent CN210910722U. While these devices are simple in structure, and workers close the discharging port once the bag is full, they cannot accurately fill bags with the specified weight of plastic granules. Workers must manually balance the approximate number of granules in each bag to ensure the weight difference between bags is within a standard range. This method is not only cumbersome but also makes precise weight control difficult, leading to significant weight differences between overweight and underweight bags, which is detrimental to sales. Therefore, the inventor has developed a new invention. Utility Model Content

[0019] The following is in conjunction with the appendix Figures 1 to 4 This utility model will be described in detail.

[0020] This utility model discloses a plastic granule quantitative discharge device, including a hopper 1 and a receiving mechanism 2. The top of the hopper 1 is provided with a feed pipe 11, and plastic granules are discharged into the hopper 1 from the feed pipe 11 and accumulate therein. The bottom of the hopper 1 is provided with a discharge port 12 for discharging plastic granules from the hopper 1. A guide rail 13 is provided below the hopper 1, and the guide rail 13 is provided with a sliding plate 14 that can abut against the discharge port 12. The sliding plate 14 can move along the guide rail 13 to change the open and closed state of the discharge port 12. One end of the slide plate 14 is provided with a connecting plate 141, and the connecting plate 141 is provided with a slot 142. The receiving mechanism 2 is provided with a lifting device 21, a lateral moving device 22 connected to the lifting device 21, and a longitudinal telescopic device 23 connected to the lateral moving device 22 in sequence. The extended end of the longitudinal telescopic device 23 is provided with a rotating device 24, and the front end of the rotating device 24 is provided with a conveying container 25. The port of the conveying container 25 corresponds to the discharge port 12. After the conveying container 25 is connected to the discharge port 12, it can receive a certain amount of plastic granules. The receiving structure allows the conveying container 25 to move along three axes. Then, the plastic granules in the conveying container 25 are poured into the corresponding packaging bag by the rotating device 24, and the material is automatically and quantitatively discharged. Specifically, after the material container 25 moves to the designated position, the longitudinal telescopic device 23 drives the material container 25 to move forward. The material container 25 pushes the slide plate 14 and moves below the discharge port 12. The plastic granules in the hopper 1 flow into the material container 25 through the discharge port 12 until the material container 25 is full. The receiving mechanism 2 drives the material container 25 to move to the packaging bag filling position. The rotating device 24 drives the material container 25 to rotate laterally, pouring the plastic granules in the material container 25 into the packaging bag, thus realizing automated quantitative discharge. The material container 25 is provided with a hook 251 on one side that can be connected to the slot 142. The longitudinal telescopic device 23 can drive the material container 25 to push the slide plate 14 and connect the material container 25 with the discharge port 12. The material container 25 can be connected to the slide plate 14 through the hook 251. When the material container 25 moves, it will push the slide plate 14, causing the slide plate 14 to open or close the discharge port 12, which can prevent plastic particles from falling to the ground and ensure that the discharge structure is safe and stable. More specifically, the slot 142 is recessed upwards. The material container 25 first moves to the designated position and then rises, so that the hook 251 engages with the slot 142. When this action is completed, the distance between the top horizontal position of the material container 25 and the bottom horizontal position of the discharge port 12 is less than 1mm. The material container 25 is then engaged with the connecting plate 141. At this time, the slide plate 14 will move with the material container 25. After the material container 25 is filled with plastic granules, the longitudinal telescopic device 23 drives the material container 25 to retract. As the material container 25 leaves the discharge port 12, the slide plate 14 will close the discharge port 12 and block the discharge port 12.After the material container 25 is moved to the designated position, the longitudinal telescopic device 23 stops operating. Finally, the lifting device 21 drives the material container 25 to descend, causing the hook 251 to disengage from the slot 142 and the slide plate 14 to disengage from the material container 25.

[0021] The receiving mechanism 2 is equipped with a fixed frame 3, and the lifting device 21 is fixedly connected to the fixed frame 3. The fixed frame 3 can be installed on a base, column or other supporting facilities to fix the receiving mechanism 2 and improve its stability.

[0022] The lifting device 21 is provided with a first slide rail 211, and the lateral moving device 22 is provided with a first slider 221 connected to the first slide rail 211. The lifting device 21 is provided with a first motor 212 that drives the first slider 221 to move. In this structure, the first motor 212 can drive the first slider 221 to move up and down, thereby changing the height position of the material container 25.

[0023] The lateral moving device 22 is equipped with a second slide rail 222, which is perpendicular to the first slide rail 211. The longitudinal telescopic device 23 is equipped with a second slider 231 connected to the second slide rail 222, and a second motor 223 is provided to drive the second slider 231 to move. In this structure, the second motor 223 can drive the second slider 231 to move laterally, causing the material container 25 to shift laterally. Through the cooperation of the lifting device 21, the lateral moving device 22, the longitudinal telescopic device 23, and the rotating device 24, the material container 25 can perform four-axis motion, which can automatically transport plastic granules in the hopper 1 to packaging bags or other packaging containers in a quantitative manner.

[0024] The material container 25 has an external rectangular shape, the discharge port 12 has a rectangular shape, and the slide plate 14 has an inverted L shape. In this design, the material container 25 is detachably connected to the rotating device 24, and the amount of material transported per batch can be changed by replacing the material container 25. Specifically, when replacing the material container 25, the material container 25 adopts an external rectangular shape. Material containers 25 with different capacities have the same length and width but different heights, which facilitates the docking of the material container 25 with the discharge port 12. When the material container 25 docks with the slide plate 14, regardless of the height of the material container 25, the connecting plate 141 can fit snugly against the material container 25.

[0025] The connecting plate 141 is provided with a groove 143 for the hook 251 to move. When the material container 25 docks with the slide plate 14, the connecting plate 141 needs to be tightly against the material container 25 to prevent excessive gaps from forming when the material container 25 docks with the slide plate 14, which could cause plastic particles to fall into the gaps. In this design, the hook 251 is a protruding structure, and the recessed depth of the groove 143 is greater than the protruding length of the hook 251, so that the hook 251 can be fully inserted into the groove 143, facilitating the docking of the hook 251 with the slot 142.

[0026] The bottom of the hopper 1 is provided with an inclined section 15, and the discharge port 12 is located at the lower end of the inclined section 15. The inclined section 15 and the discharge port 12 cooperate to form a funnel-like shape at the bottom of the hopper 1. Under the action of gravity, the inclined section 15 can guide the plastic particles to the discharge port 12, thereby improving the discharge stability.

[0027] The hopper 1 is provided with observation windows 16 on both sides, and transparent plates are installed inside the observation windows 16. The staff can observe the volume of plastic granules in the hopper 1 through the observation windows 16. When the volume of plastic granules in the hopper 1 is too low, the staff can operate the feed pipe 11 to discharge the material, so as to avoid the material transport container 25 transporting material empty.

[0028] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this invention. The content of this specification should not be construed as a limitation of this utility model.
