[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2This utility model provides a quantitative dispensing device for plastic rice grains, including a support frame 1, a first conveyor 2, and a weighing platform 3. A second conveyor 4 is installed on the weighing platform 3. The second conveyor 4 and the first conveyor 2 are on the same horizontal line. The first conveyor 2 is responsible for transporting empty storage bags to the designated dispensing position, while the second conveyor 4 transports the dispensed storage bags out of the weighing platform 3. The fact that the two are on the same horizontal line ensures a smooth transition during the transportation of the storage bags and avoids jamming or deviation. The weighing platform 3 is used to detect the weight of the storage bags containing plastic rice grains to achieve quantitative dispensing.

[0022] The feeding rack 5 is connected to the top of the support 1 at the bottom, and serves to temporarily store plastic rice grains to be packaged, so that the plastic rice grains can enter the dispensing cylinder 6 in an orderly manner.

[0023] Two distributing cylinders 6 are respectively suspended inside the bracket 1 by fixing frames 7. The fixing frames 7 are made of suitable metal profiles and can be connected to the bracket 1 and the distributing cylinders 6 by welding, bolt fixing or other means to ensure that the distributing cylinders 6 are installed stably.

[0024] Two elastic sealing elements 8 are respectively installed inside the bracket 1 and respectively seal the bottom of the two dispensing cylinders 6;

[0025] The driving component 9 is located inside the bracket 1 and is in contact with the two elastic closing components 8;

[0026] The drive unit 9 is used to drive the two elastic sealing members 8 to alternately seal the bottom of the two dispensing cylinders 6.

[0027] Specifically, refer to Figure 2 The elastic closure 8 includes a mounting plate 81, which serves as the mounting base for the elastic closure 8 and is fixed inside the bracket 1; a bearing seat 82 is used to mount the shaft 83, ensuring that the shaft 83 can rotate; the shaft 83 is the support shaft for the rotation of the closure plate 84; the closure plate 84 is in contact with the bottom of the distribution cylinder 6, realizing the closure or opening of the bottom of the distribution cylinder 6 and controlling the material falling; the mounting rod 85 provides an installation position for the spring 86; the spring 86 provides the closure plate 84 with an elastic restoring force, and when the driving component 9 releases the drive of the driving rod 87, the spring 86 pulls the closure plate 84 back to close the bottom of the distribution cylinder 6; the driving rod 87 is used to receive the driving force of the driving component 9, driving the shaft 83 and the closure plate 84 to rotate.

[0028] Specifically, refer to Figure 2The driving component 9 includes a servo motor 91 installed inside the bracket 1; a cam 92 installed on the output end of the servo motor 91; the cam 92 is in contact with two driving rods 87, and by utilizing its contour curve, it is in contact with the two driving rods 87 when rotating, pushing the driving rods 87 to drive the shaft 83 to rotate, thereby controlling the closing plate 84 to open the bottom of the dispensing cylinder 6, realizing the material falling and dispensing. In conjunction with two elastic closing components 8, the bottoms of the two dispensing cylinders 6 are alternately closed to achieve efficient dispensing.

[0029] Specifically, refer to Figure 1 Limit frames 10 are installed on both sides of conveyor 12 and conveyor 24 to limit the conveyed storage bags, etc.

[0030] Specifically, refer to Figure 2 The lower part of the dispensing cylinder 6 is constricted and has a sloping bottom. This design is to fit closely with the rotating sealing plate 84, ensuring the sealing performance of the sealing plate 84 when sealing the bottom of the dispensing cylinder 6, preventing material leakage, and improving the metering accuracy.

[0031] Working principle

[0032] When needed, the servo motor 91 of the drive component 9 starts, driving the cam 92 to rotate. During the rotation of the cam 92, it engages with the drive rod 87 of one of the elastic sealing components 8, pushing the drive rod 87 to rotate around the shaft 83. The shaft 83 drives the sealing plate 84 to rotate, causing the bottom of one of the distributing cylinders 6 to open, and the material falls into the collection bag on the second conveyor 4 below. At this time, the collection bag has been transported by the first conveyor 2 to the designated position on the weighing platform 3. At the same time, the elastic sealing component 8 of the other distributing cylinder 6 remains closed under the action of the spring 86, continuing to temporarily store the material and prepare for dispensing. This cycle is repeated to achieve the effect of alternating closing and opening of the bottom of the two distributing cylinders 6, achieving dispensing and filling at the same time.

[0033] Conveyor 2 transports empty storage bags to conveyor 4 on weighing platform 3. During the filling process of material distribution cylinder 6, weighing platform 3 detects the weight of storage bags and materials in real time. After the filling quantity is completed, conveyor 4 transports the storage bags containing the quantitative plastic rice grains out to enter the next production stage. At the same time, conveyor 2 continues to transport new empty storage bags to ensure that the packaging process is continuous.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
