Description

Technical Field

[0001] This utility model relates to the field of metering and packaging technology, and in particular to an automatic metering and packaging device for plastic rice grains. Background Technology

[0002] In the plastics processing industry, plastic pellets are a basic raw material, and their metering and packaging process has a significant impact on production efficiency and cost control. The widely used plastic pellet metering and packaging equipment on the market mostly adopts a rotary metering structure. This structure uses multiple fixed-volume receiving slots on a rotary table to achieve continuous metering and unloading of materials by rotating the table. After the plastic pellets are poured into the feeding device of the equipment, the material is evenly filled into the receiving slots of the rotary table under the action of gravity or feeding mechanism. As the rotary table rotates, the receiving slots filled with material move to the unloading position. At this time, the receiving slots are aligned with the unloading port of the equipment, and the material falls into the packaging container below by its own gravity to complete the packaging.

[0003] However, the capacity of the container in the existing technology is fixed. When the production line needs to be modified to produce different specifications of plastic rice, the machine must be stopped to replace the turntable with the corresponding capacity, which affects the continuity of production and increases the difficulty of operation. At the same time, for small-batch, multi-specification plastic rice packaging needs, enterprises need to stock a variety of turntables of different specifications, which will undoubtedly increase the storage cost and management difficulty of the equipment.

[0004] Therefore, based on the above situation, we designed an automatic metering and packaging equipment for plastic rice grains to solve the above problems. Utility Model Content

[0005] This invention provides an automatic metering and packaging device for plastic rice grains to solve the problem in the prior art that it is inconvenient to make timely adjustments for packaging with different metering requirements.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] An automatic metering and packaging device for plastic rice grains includes a support, a container, a scraper, and an adjusting component. The support has a feeding channel for discharging material. The container is rotatably connected to the upper end of the support via a drive motor. The container includes a first connecting part and a second connecting part coaxially arranged and slidably connected to the first connecting part. Through holes are provided at corresponding positions of the first and second connecting parts, and a metering chamber is formed between two adjacent through holes. When the metering chamber is opposite to the feeding channel, the material in the metering chamber falls out. The scraper is connected to the upper end of the support via a connecting mechanism and is used to scrape the material in the container into the metering chamber when the container rotates. The adjusting component is connected to the container and is used to adjust the axial displacement between the first and second connecting parts to change the volume of the metering chamber.

[0008] Preferably, the adjusting member is threadedly connected to the first connecting part, and its bottom is rotatably connected to the second connecting part.

[0009] Preferably, the scraper divides the first connecting part into a feeding area and a discharging area, and the upper end of the feeding area is also provided with a receiving hopper for conveying materials into the feeding area.

[0010] Preferably, the connecting mechanism includes a connecting rod disposed on the support member, both ends of the scraper are movably sleeved on the connecting rod, and the upper end of the scraper is provided with a limiting member that is threadedly connected to the connecting rod.

[0011] Preferably, the support member is provided with a scale plate for indicating the distance between the first connecting part and the second connecting part.

[0012] Preferably, a friction plate is detachably connected to the bottom end of the scraper.

[0013] The beneficial effects of this utility model are: by adjusting the distance between the first connecting part and the second connecting part through the adjusting component, the volume of the measuring chamber can be adjusted, which is convenient for adjusting the packaging amount according to different packaging needs of plastic rice grains, without the need to frequently change the measuring cup, making it faster and more convenient.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0021] Reference Figures 1-4 As shown, an automatic metering and packaging device for plastic rice grains includes a support member 1 and a mounting member 2. A feeding channel 11 for feeding is provided on the support member 1. The mounting member 2 is rotatably connected to the upper end of the support member 1 via a drive motor 3. The mounting member 2 includes a first connecting part 21 and a second connecting part 22 coaxially arranged with and slidably connected to the first connecting part 21. Through holes are provided at corresponding positions of the first connecting part 21 and the second connecting part 22. A metering chamber 23 is formed between two adjacent through holes. When the metering chamber... When metering chamber 23 is opposite to the feeding channel 11, the material in metering chamber 23 falls out. The bottom surface of the first connecting part 21 is in contact with the inner top surface of the second connecting part 22. When metering chamber 23 is completely misaligned with the feeding channel 11, the material in metering chamber 23 will not fall out and will move synchronously with the rotation of the supporting part 2. When metering chamber 23 moves to partially or completely overlap with the feeding channel 11, the material in metering chamber 23 will fall out from the feeding channel 11. When packaging, packaging bags or the like can be set at the output end of the feeding channel 11 for packaging.

[0022] Furthermore, a scraper 4 is connected to the upper end of the support member 1 via a connecting mechanism. When the bearing member 2 drives the material inside to rotate synchronously, the scraper 4 scrapes the material inside the bearing member 2, causing the material to enter the metering chamber 23. This makes the height of the material in the metering chamber 23 flush with the inner top wall of the first connecting part 21, thus achieving the metering of plastic rice grains. The volume of the material in the metering chamber 23 is the required packaging capacity. When it is necessary to adjust the amount of plastic rice grains to be packaged, it is usually necessary to stop the machine and replace the metering chamber 23 with a metering chamber 23 of different volumes. Therefore, this solution provides an adjusting member 5 on the bearing member 2 to adjust the axial displacement between the first connecting part 21 and the second connecting part 22 to change the volume of the metering chamber 23.

[0023] Specifically, the adjusting member 5 is threadedly connected to the first connecting part 21, and the bottom of the adjusting member 5 is rotatably connected to the second connecting part 22. When the adjusting member 5 is rotated clockwise or counterclockwise, since the first connecting part 21 and the second connecting part 22 are slidably connected, the first connecting part 21 will move closer to or further away from the second connecting part 22. When the first connecting part 21 moves closer to the second connecting part 22, the volume in the measuring chamber 23 decreases, and vice versa. Furthermore, the support member 1 is also provided with a scale plate 7 for indicating the distance between the first connecting part 21 and the second connecting part 22. When adjusting by the adjusting rod, the distance is adjusted by referring to the first connecting part 22. The position of the measuring chamber 23 is determined by the scale value on the scale plate 7 corresponding to the upper end of the first connecting part 21. For example, when the upper end of the first connecting part 21 points to a height of 10cm on the scale plate 7, the volume of the measuring chamber 23 is adjusted to 1 liter. When it points to a height of 12cm on the scale plate 7, the volume of the measuring chamber 23 is adjusted to 1.2 liters, and so on. In actual use, the correspondence between the two can be obtained by measurement or other methods, so it will not be elaborated on here. The volume of the measuring chamber 23 can be adjusted by adjusting the position between the first connecting part 21 and the second connecting part 22 through the adjusting part 5, which makes it more convenient to use packaging with different measurement requirements.

[0024] Reference Figure 4 As shown, further, the scraper 4 divides the first connecting part 21 into a feeding area 211 and a discharging area 212. The upper end of the feeding area 211 is also provided with a receiving hopper 213 for conveying material into the feeding area 211. The receiving hopper 213 contains plastic rice grains that need to be packaged. They are first fed into the feeding area 211 and fall into a partial metering hopper in the feeding area 211. As the receiving component 2 rotates, it will drive the plastic rice grains in the feeding area 211 to rotate synchronously. When the material moves to the point of contact with the scraper plate 4, it is intercepted by the scraper plate 4, thus preventing the plastic grains in the feeding area 211 from entering the discharging area 212. At the same time, it also smooths out the plastic grains in the metering bin 23, so that the plastic grains entering the metering bin 23 have the same volume. Meanwhile, the scraper plate 4 can also intercept the material falling from the receiving hopper 213, preventing it from falling into the discharging area 212 and falling through the discharging channel 11, which would affect the metering accuracy of the packaging.

[0025] The connecting mechanism includes a connecting rod 6 mounted on the support member 1. Both ends of the scraper plate 4 are movably sleeved on the connecting rod 6, and the upper end of the scraper plate 4 is provided with a limiting member 61 that is threadedly connected to the connecting rod 6. As the height of the first connecting part 21 is adjusted, the height of the scraper plate 4 will also be adjusted synchronously. After the adjustment is completed, the limiting member 61 can be rotated to limit the upper end of the scraper plate 4 to prevent the up-and-down shaking of the scraper plate 4 from affecting the scraping effect on the plastic rice grains. However, it should be noted that the limiting member does not need to be in close contact with the scraper plate 4 to avoid excessive friction between the scraper plate 4 and the first connecting part 21.

[0026] Reference Figure 1 As shown, furthermore, a friction plate 41 is detachably connected to the bottom end of the scraper 4. The friction plate 41 can be made of some wear-resistant materials, such as nitrile rubber or ultra-high molecular weight polyethylene, to improve the service life of the scraper 4 and the first connecting part 21, and the detachable method facilitates the replacement of damaged friction plates 41.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
