[0002] In the plastic powder processing industry, the accuracy and efficiency of batching are directly related to the quality and production cost of the product. The traditional method of plastic powder batching mainly relies on manual operation, which not only has the problems of low batching accuracy and low efficiency, but also easily leads to material waste and product quality fluctuations in the production process. Specifically, the traditional batching method faces the following challenges:

[0003] It is difficult to ensure the accuracy of ingredients: When manually mixing ingredients, it is difficult to achieve accurate mixing every time due to factors such as differences in operator experience, distraction or fatigue. Even experienced workers cannot avoid errors during long hours of work, resulting in inaccurate ingredient ratios and affecting product quality.

[0004] Low production efficiency: The traditional batching method requires a lot of manual work, from weighing, mixing to feeding, each link takes a lot of time. With the expansion of production scale, this manual batching method has gradually become a key factor restricting the improvement of production efficiency.

[0005] Material blockage and uneven dispersion: During the batching process, plastic powder tends to accumulate in the conveying pipe or batching device, causing blockage. In addition, due to the lack of an effective dispersion mechanism, the material is often unevenly distributed when added to subsequent equipment, affecting the uniformity and consistency of the product.

[0006] Residual materials are difficult to clean: After long-term use, traditional batching devices are prone to accumulate residual materials inside. These residual materials not only increase the difficulty and cost of cleaning, but may also cause pollution to subsequent production and affect product quality. Utility Model Content

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a plastic powder automatic batching device, comprising a box body, a servo motor and a driving cylinder, the box body is in the shape of a cylinder, and both side walls of the box body are equipped with feeding ports, the servo motor is fixedly connected to the top of the box body, the driving end of the servo motor is fixedly connected to a driving rod, the outer surface of the driving rod is slidably sleeved with a movable sleeve, the driving rod is clamped in the interior of the movable sleeve, the movable sleeve passes through and is fixedly connected with a first movable block, the bottom end of the movable sleeve is fixedly connected with a second movable block, the interior of the box body is fixedly connected with a material guide plate, the material guide plate is in the shape of a cylinder, and the upper and lower surfaces of the material guide plate are provided with truncated cone-shaped grooves, the driving cylinder passes through the top of the box body, the movable end of the driving cylinder is fixedly connected with a movable plate, the top end of the movable sleeve passes through the movable plate, the outer surface of the top end of the movable sleeve is fixedly connected with two fixing rings, and the upper and lower surfaces of the movable plate are respectively in contact with the two fixing rings.

[0009] Preferably, the movable sleeve passes through the truncated cone-shaped slot of the guide plate.

[0010] Preferably, the upper and lower surfaces of the first movable block and the second movable block are both arc surfaces, the side surfaces of the first movable block and the second movable block are both inclined curved surfaces, and the two truncated cone-shaped grooved inner walls of the guide plate are respectively adapted to the side surfaces of the first movable block and the second movable block.

[0011] Preferably, the feed inlet is located above the guide plate.

[0012] Preferably, a discharge port is provided at the bottom of the box body.

[0013] The utility model has the following beneficial effects:

[0014] 1. The driving cylinder in the automatic dosing device for plastic powder can drive the movable plate and the movable sleeve to move up and down, thereby adjusting the distance between the first movable block on the movable sleeve and the material guide plate. This design allows the user to flexibly adjust the rate at which the material passes through the gap according to production needs, thereby achieving precise control of the material addition rate. By quickly and accurately adjusting the material addition rate, the device can ensure the continuity and stability of the production line, avoid production interruptions or product quality problems caused by uneven material addition, and thus improve overall production efficiency.

[0015] 2. In this automatic plastic powder batching device, the servo motor drives the movable sleeve to rotate. This action not only effectively prevents the slot on the guide plate from being blocked by materials, but also promotes the flow and dispersion of materials through the rotation of the movable sleeve. The second movable block at the bottom of the movable sleeve is located below the slot of the guide plate, which can further disperse the materials dropped from the slot, ensuring that the materials discharged from the box outlet can be evenly and stably added to the subsequent equipment. This design helps to improve the consistency and quality stability of the product.

[0016] 3. The driving cylinder of the automatic plastic powder batching device is not only used to adjust the material addition rate, but also has a cleaning function. When cleaning is required, the driving cylinder can drive the first movable block to move downward so that it fits tightly with the inner wall of the slot at the top of the guide plate, and clean the residual material on the inner wall of the slot by rotating the movable sleeve. Similarly, the driving cylinder can also drive the second movable block to move upward to clean the residual material on the inner wall of the slot at the bottom of the guide plate. This automatic cleaning function greatly reduces the maintenance burden of the operator, reduces the downtime for cleaning, and improves the operating efficiency of the equipment and the overall stability of the production line.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] like Figure 1-2As shown, the embodiment of the utility model provides an automatic dosing device for plastic powder, including a box body 1, a servo motor 3 and a driving cylinder 8. The box body 1 is in the shape of a cylinder, and both side walls of the box body 1 are equipped with a feed port 2. The servo motor 3 is fixedly connected to the top of the box body 1, and the driving end of the servo motor 3 is fixedly connected to a driving rod 9. The outer surface of the driving rod 9 is slidably sleeved with a movable sleeve 4, and the driving rod 9 is clamped in the inside of the movable sleeve 4. The movable sleeve 4 penetrates and is fixedly connected with a first movable block 5, and the bottom end of the movable sleeve 4 is fixedly connected with a second movable block 6. The inside of the box body 1 is fixedly connected with a guide plate 7, and the shape of the guide plate 7 is a cylinder. The upper and lower surfaces of the guide plate 7 are provided with truncated cone-shaped grooves. The driving cylinder 8 penetrates the top of the box body 1, and the movable end of the driving cylinder 8 is fixedly connected with a movable plate 10. The top end of the movable sleeve 4 penetrates the movable plate 10, and the outer surface of the top end of the movable sleeve 4 is fixedly connected with two fixing rings 11, and the upper and lower surfaces of the movable plate 10 are respectively in contact with the two fixing rings 11.

[0022] The movable sleeve 4 passes through the truncated cone-shaped slot design of the guide plate 7, so that the material can flow more smoothly when passing through, effectively avoiding the occurrence of blockage. At the same time, the rotation of the movable sleeve 4 further promotes the dispersion and mixing of the material, ensuring the uniformity of the ingredients.

[0023] The upper and lower surfaces of the first movable block 5 and the second movable block 6 are arc surfaces, and the side surfaces are inclined curved surfaces. This design enables them to fit tightly against the truncated cone-shaped grooved inner wall of the guide plate 7. When cleaning is required, the first movable block 5 and the second movable block 6 can move along the inner wall to easily scrape off the remaining materials, greatly improving the cleaning efficiency and reducing the downtime for maintenance. The two truncated cone-shaped grooved inner walls of the guide plate 7 are respectively matched with the sides of the first movable block 5 and the second movable block 6. This design not only ensures the smoothness of the movement, but also enhances the overall stability and durability of the device. The adapted structure reduces friction and wear, and extends the service life of the device.

[0024] The feed port 2 is located above the guide plate 7, so that the material can directly and accurately enter the device, reducing the loss and error of the material during the feeding process. This design helps to improve the accuracy and stability of the ingredients and ensure the consistency of product quality.

[0025] The bottom of the box body 1 is provided with a discharge port, so that the materials after batching and mixing can be discharged from the discharge port evenly and stably, which helps the subsequent production process to proceed smoothly and improves the overall efficiency of the production line and product quality.

[0026] Working principle: When using the automatic batching device for plastic powder, first, the plastic powder to be batched enters the interior of the box 1 through the feed port 2 set on the box 1. The position design of the feed port 2 ensures that the material can enter the box 1 smoothly and reduces the splashing and loss of the material during the feeding process. Once the material enters the box 1, the guide plate 7 inside the box 1 plays a key role. The design of the guide plate 7 is to effectively concentrate the dispersed materials in the box 1 into the truncated cone-shaped slot at the top of the guide plate 7. This design not only improves the efficiency of material batching, but also makes the subsequent batching process more accurate and controllable. As the material continues to enter, the slot at the top of the guide plate 7 will gradually fill with material. At this time, the movable sleeve 4 in the device begins to play its role. The movable sleeve 4 passes through the truncated cone-shaped slot of the guide plate 7 and can move up and down as needed. A first movable block 5 is installed on the movable sleeve 4, which can move up and down in the top slot of the guide plate 7 according to the drive of the driving cylinder 8, thereby adjusting the distance between the movable sleeve 4 and the guide plate 7. This adjustment process directly affects the rate at which the material passes through the slot, thereby achieving precise control of the material addition rate. When the servo motor 3 drives the driving rod 9 to drive the movable sleeve 4 to rotate, it also promotes the flow and dispersion of the material in the slot. This helps to prevent the accumulation and blockage of materials in the slot and ensure that the materials can fall evenly from the slot. At the same time, the second movable block 6 at the bottom of the movable sleeve 4 is located below the slot of the guide plate 7, which will further disperse the materials falling from the slot and ensure that the materials can flow evenly and stably to the discharge port at the bottom of the box 1. Finally, the accurately batched and dispersed materials are discharged through the discharge port at the bottom of the box 1 and added to the subsequent production equipment. The entire batching process is automated and precise, greatly improving production efficiency and product quality. In addition, the device also has an automatic cleaning function. When cleaning is required, the driving cylinder 8 can drive the first movable block 5 and the second movable block 6 to fit the top and bottom slot inner walls of the guide plate 7 respectively, and clean the residual materials through the rotation of the movable sleeve 4. This design greatly reduces the maintenance burden on operators and improves the overall stability and reliability of the equipment.
