Description

A precise metering and feeding device for plastic granules Technical Field

[0001] This utility model relates to the field of plastic product manufacturing, and more specifically, it relates to a precise metering and feeding device for plastic granules. Background Technology

[0002] Plastic products are very common in people's lives and industrial production, greatly facilitating people's production and life. When producing plastic products, plastic granules need to be added to the production machine. During the process of adding granules, the amount added needs to be precisely controlled to ensure high-quality production. In the production of plastic products, many types of granules may need to be added, or different types of plastic products may require different granules. Existing feeding devices cannot store multiple different granules simultaneously. Therefore, when producing different plastic products, operators need to manually add plastic granules to the feeding device, affecting the feeding of materials into the production equipment and impacting the production of plastic products. Furthermore, existing feeding devices generally control the feeding of materials through valves. Due to the gaps between granules, it is impossible to precisely control the amount of granules entering the production equipment, thus affecting the production of plastic products.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a precise metering and feeding device for plastic granules, which has the following beneficial effects:

[0017] 1. This utility model, by setting an intermediate column and fixing plates, divides the internal space of the main barrel into multiple parts when placing the plastic granules to be added into the main barrel. This allows the plastic granules to be placed between two different placement plates. At the same time, the scale lines set on the intermediate column indicate the amount of plastic granules to be placed, which facilitates the addition of different plastic granules into the plastic product manufacturing machine and the confirmation of the amount of plastic granules added, thereby facilitating the production of plastic products.

[0018] 2. This utility model, by setting up a feeding hopper and a feeding port, allows the feeding hopper to be rotated by the cooperation of the first rotating column and the first rotating hole after the required granules are selected, so that the feeding hopper reaches the placement slot for placing the required granules. The second electric push rod set on the mounting frame of the main barrel extends and drives the connecting plate and the mounting frame to move, thereby pulling the blocking plate out of the placement slot. The granules pass through the feeding port and enter the feeding hopper, and the discharge pipe opened on the feeding hopper discharges the entire device, thus facilitating the use of the entire feeding device.

[0019] 3. This utility model, by setting up a pushing structure, allows the first rotating column to rotate during the feeding of plastic granules. This rotation, driven by a motor, causes the fixed frame to rotate, and the pushing plate to rotate to the upper end of the required granules. The extension of the first electric push rod then causes the pushing plate to descend, pushing the plastic granules downward. This facilitates the discharge of plastic granules from the main barrel and allows the scale lines on the pushing plate and the middle column to be aligned, making it easier to determine the discharge amount of plastic granules and thus facilitating the use of the entire feeding device.

[0031] In this embodiment, the main structure of the feeding device is formed by the main barrel 1, the baffle plate 11, and the second electric push rod 23.

[0032] More specifically, the pusher structure facilitates the discharge of granules while also making it easy to determine the amount of granules discharged.

[0033] Please refer to Figures 1-5 for one embodiment of precise granule discharge: A hopper 13 is provided at the lower end of the main body barrel 1, and a discharge pipe 14 is provided on the hopper 13. A first rotating column 15 is fixedly provided at the lower end of the main body barrel 1, and a first rotating hole 16 is provided on the hopper 13. An mounting plate 17 is provided at the lower end of the rotating column. The first rotating column 15 and the first rotating hole 16 cooperate with each other and are rotatably connected.

[0034] Specifically, after the required granules are selected, the feeding hopper 13 is rotated by the cooperation of the first rotating column 15 and the first rotating hole 16, so that the feeding hopper 13 reaches the placement slot 10 for placing the required granules. The second electric push rod 23 set on the mounting frame 22 of the main body barrel 1 extends and drives the connecting plate and the mounting frame 22 to move, thereby pulling the blocking plate 11 out of the placement slot 10. The granules pass through the feeding port 12 and enter the feeding hopper 13, and are discharged through the discharge pipe 14 opened on the feeding hopper 13. During the feeding of plastic granules, the motor 20 drives the first rotating column 15 to rotate, thereby driving the fixed frame 7 to rotate, so that the push plate 9 rotates to the upper end of the required granules. The extension of the first electric push rod 8 drives the push plate 9 to descend, and the push plate 9 pushes the plastic granules down, so that the plastic granules are discharged from the main body barrel 1. At the same time, it is easy for the push plate 9 and the scale line 6 set on the middle column 2 to cooperate, so as to easily determine the discharge amount of plastic granules.

[0035] In summary, when using it as a whole:

[0036] When the plastic granules to be added are placed in the main body barrel 1, the space inside the main body barrel 1 is divided into multiple parts by multiple fixing plates 3 set on the intermediate column 2, so that the plastic granules are placed between two different placement plates, and the amount of plastic granule powder is clearly indicated by the scale line 6 set on the intermediate column 2.

[0037] After the required granules are selected, the feeding hopper 13 is rotated by the cooperation of the first rotating column 15 and the first rotating hole 16, so that the feeding hopper 13 reaches the placement slot 10 for placing the required granules. The second electric push rod 23 set on the mounting frame 22 of the main body barrel 1 extends and drives the connecting plate and the mounting frame 22 to move, thereby pulling the blocking plate 11 out of the placement slot 10. The granules pass through the feeding port 12 and enter the feeding hopper 13, and are discharged through the discharge pipe 14 opened on the feeding hopper 13. During the feeding of plastic granules, the motor 20 drives the first rotating column 15 to rotate, thereby driving the fixed frame 7 to rotate, so that the push plate 9 rotates to the upper end of the required granules. The extension of the first electric push rod 8 drives the push plate 9 to descend, and the push plate 9 pushes the plastic granules down, so that the plastic granules are discharged from the main body barrel 1. At the same time, it is easy for the push plate 9 and the scale line 6 set on the middle column 2 to cooperate, so as to easily determine the discharge amount of plastic granules.
