DETAILED DESCRIPTION

[0016] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model. In the accompanying drawings, all the same reference numerals refer to the same components. Figures 1-5 As shown, this utility model provides a plastic granule quantitative dispensing machine, including a frame 1, a feeding mechanism 2 fixed on the frame 1; a stirring mechanism 3 below the feeding mechanism 2; a quantitative mechanism 4 below the stirring mechanism 3; a controller 6 fixed on the side of the frame 1; the feeding mechanism 2 includes a feeding hopper 21 fixed to the top of the frame 1 and a vibrator 22; the stirring mechanism 3 includes a servo motor 31, a servo motor 31 fixed in the middle of the frame 1; a reducer 32, a reducer 32 fixed at the output end of the servo motor 31; a rotating shaft 33, a rotating shaft 33 coaxially connected to the output end of the reducer 32; a bushing 34, a bushing 34 fixed to the outside of the rotating shaft 33; a fixed disk 35, a fixed disk 35 fixed above the bushing 34; a turntable 36, a turntable 36 fixedly connected to the top of the rotating shaft 33; a stirring paddle 37, a stirring paddle 37 fixedly connected to one end of the rotating shaft 33; and a dispensing cylinder 38, a plurality of dispensing cylinders 38 fixedly connected to the bottom of the turntable 36.

[0017] The quantitative mechanism 4 includes a fixed plate 41 fixed to the side of the frame 1; a funnel 42, with the funnel 42 fixed at the center of the fixed plate 41; a plastic hose 43, which is connected to the bottom of the funnel 42; an encoder 44, which is rotatably connected to the bottom of the reducer 32; a support frame 45, which is fixed to one side of the frame 1; a slide table 46, with two parallel slide tables 46 fixedly connected to both sides of the support frame 45; a slide table base plate 47, with the two slide tables 46 fixed on the slide table base plate 47 respectively; a drive cylinder 48, which is provided between the two slide tables 46; and a clamping mechanism 5, which is fixed on the two slide table base plates 47.

[0018] In this embodiment, plastic granules enter the packaging machine through the feed hopper 21 and are evenly dispersed onto the turntable 36 under the action of the vibrator 22.

[0019] The method of using this utility model is as follows:

[0020] 1. When it is necessary to quantitatively dispense plastic, firstly, people pour plastic granules into the feed hopper 21 through the conveyor belt, and then start the feeding mechanism 2 and the stirring mechanism 3. The vibration of the feeding mechanism 2 causes the plastic to fall into the stirring mechanism 3.

[0021] 2. The encoder 44 converts the angle rotated by the turntable 36 into an electrical signal and transmits it to the controller 6. When the turntable 36 rotates through the set angle, the controller 6 sends a completion signal to the drive cylinder 48 to move. At the same time, the controller 6 sends a completion signal to the servo motor 31 and the vibrator 22, causing the servo motor 31 to stop rotating and the vibrator 22 to stop vibrating, thereby stopping the turntable 36 from feeding the feed mechanism 4.

[0022] 3. The drive cylinder 48 receives an electrical signal from the controller 6 and controls the drive cylinder 48 to move. The moving end of the drive cylinder 48 controls the moving roller 51 to move towards the fixed roller 52, thereby causing the pressing belts 54 on both sides to gradually close until the plastic hose 43 is completely closed, thereby blocking the further flow of plastic granules and completing the quantitative dispensing of plastic granules.

[0023] For further details, please refer to the appendix. Figure 5 The clamping mechanism 5 includes two movable rollers 51 and two fixed rollers 52. The bottom of the movable rollers 51 is fixedly connected to the movable end of the drive cylinder 48 and is used to drive the movable rollers 51 to move towards the fixed rollers 52. The fixed rollers 52 are connected to the fixed end of the drive cylinder 48. Several pressure rollers 53 are also provided in the middle of the movable rollers 51. The bottom of the pressure rollers 53 is fixed on the slide base plate 47. Pressure bands 54 are sleeved on both the movable rollers 51 and the fixed rollers 52. The circumference of the pressure rollers 53 is in contact with the inner surface of the pressure bands 54.

[0024] In this embodiment, the position of the pressure roller 53 is horizontally adjustable. By adjusting the position of the pressure roller 53, the pressure belt 54 in contact with it is squeezed, so that the pressure belt 54 is in a taut state. When the moving roller 51 moves toward the fixed roller 52, the symmetrically arranged pressure belts 54 gradually move toward each other and gradually squeeze the plastic hose 43, causing the plastic hose 43 to deform and finally close completely, blocking the plastic particles from continuing to flow downward, thus completing the quantitative dispensing of particles.

[0025] For further details, please refer to the appendix. Figure 4 The encoder 44 is fixedly connected to the output end of the reducer 32 and is used to count the angle rotated by the reducer 32 shaft, thereby calculating the amount of released particles. The encoder 44 is electrically connected to the controller 6 and is used to provide start and stop signals to the servo motor 31 and the vibrator 22. In this embodiment, the encoder 44 is installed directly below the reducer 32, and its top is connected to the output shaft of the reducer 32 through a coupling. It can synchronously record the angle rotated by the output shaft, thereby converting the angle rotated by the turntable 36 into an electrical signal and transmitting it to the controller 6. When the turntable 36 rotates through the set angle, the controller 6 sends a completion signal to the drive cylinder 48 to move. At the same time, the controller 6 sends a completion signal to the servo motor 31 and the vibrator 22, causing the servo motor 31 to stop rotating and the vibrator 22 to stop vibrating.

[0026] 6. Furthermore, the drive cylinder 48 is electrically connected to the controller 6 and is used to receive electrical signals provided by the controller 6. The drive cylinder 48 controls the slide table 46 at the bottom of the moving roller 51 to move horizontally towards the fixed roller 52, which is used to drive the pressing band 54 to squeeze the plastic hose 43 located between the moving roller 51 and the fixed roller 52, thereby completing the closing of the plastic hose 43.

[0027] In this embodiment, the drive cylinder 48 receives an electrical signal from the controller 6 and controls the drive cylinder 48 to move. The moving end of the drive cylinder 48 controls the moving roller 51 to move toward the fixed roller 52, thereby causing the pressing bands 54 on both sides to gradually close together until the plastic hose 43 is completely closed, thus blocking the further outflow of plastic particles.

[0028] For further details, please refer to the appendix. Figure 3 The fixed disk 35 has a material passage hole on its edge, which is located directly above the funnel 42. The distributing cylinder 38 is evenly distributed around the circumference of the turntable 36 and is connected to the turntable 36. The bottom of the distributing cylinder 38 corresponds to the position of the material passage hole and is used to receive the material in the distributing cylinder 38. In this embodiment, the size of the material passage hole on the edge of the fixed disk 35 matches the diameter of the bottom through hole of the distributing cylinder 38 and is connected to it. When the plastic granules in the turntable 36 are continuously stirred by the stirring paddle 37 and spread evenly, they slide into the distributing cylinder 38 under the action of gravity and fill the distributing cylinder 38. The material in the distributing cylinder 38 then enters the funnel 42 below through the material passage hole. When the servo motor 31 stops rotating, the position of the material passage hole and the bottom through hole of the distributing cylinder 38 are misaligned, preventing the plastic granules in the turntable 36 from further entering the distributing cylinder 38.

[0029] 8. Furthermore, a slide rail 7 is fixedly connected to one side of the bottom of the frame 1. The slide rail 7 is arc-shaped and the bottom end of the slide rail 7 is connected to the packaging bag.

[0030] This utility model is a plastic granule quantitative dispensing machine. By stirring the plastic granules with a stirring paddle, the plastic granules can be pushed into the dispensing cylinder, preventing them from being thrown out and falling when the stirring mechanism rotates, thus ensuring the continuity of material supply. In addition, the electrical signal of the number of rotations sent by the encoder is sent to the controller, which then controls the clamping and releasing actions of the clamping mechanism, and at the same time controls the turntable to quantitatively supply plastic granule material, thereby achieving the effect of precise quantitative dispensing of plastic granules.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
