Description

Technical Field

[0001] This utility model belongs to the field of plastic powder processing technology, and relates to automatic batching devices, particularly an automatic batching device for plastic powder. Background Technology

[0002] In the plastics production industry, plastic powder is a key raw material, and its batching process is crucial. In practical applications, plastic powder often needs to be mixed with other fine particles or dust-like materials. A search revealed a Chinese patent with authorization number CN222875022U, which discloses an automatic batching device for plastic powder. This device includes a cylindrical housing, a servo motor, and a drive cylinder. The housing has inlets on both side walls. The servo motor is fixedly connected to the top of the housing, and a drive rod is fixedly connected to its drive end. A movable sleeve is slidably fitted onto the outer surface of the drive rod. The drive cylinder in the device can drive a movable plate and a movable sleeve to move up and down, thereby adjusting the distance between the first movable block on the movable sleeve and the guide plate. This design allows users to flexibly adjust the rate at which material passes through the gap according to production needs, thus 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, avoiding production interruptions or product quality problems caused by uneven material addition, thereby improving overall production efficiency.

[0003] The aforementioned patent's automatic plastic powder dispensing device has the following shortcomings: although the device is equipped with two feed inlets, it is difficult to independently add different materials. At the same time, it is difficult to flexibly adjust the rate at which the material passes through the gap to achieve precise control of the material addition rate, but it is impossible to accurately control the amount of material. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an automatic plastic powder dispensing device. The technical problem this invention aims to solve is: how to achieve automatic and quantitative addition of multiple ingredients.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An automatic plastic powder dispensing device includes a feeding box with a feeding port at the bottom. Four feeding mechanisms are evenly spaced around the top circumference of the feeding box. Each feeding mechanism includes a conical unloading box fixedly embedded on one side of the top of the feeding box. The top of the feeding box has a rectangular opening adapted to the conical unloading box. A U-shaped baffle is fixedly connected to the bottom of the conical unloading box. A fixing block is fixedly connected to the outer side of the conical unloading box away from the center of the feeding box. Two sliding rods are fixedly connected to the side of the fixing block near the edge of the feeding box. The other ends of the two sliding rods are fixedly connected to the same limiting plate. The circumferential surface of the two sliding rods is slidably fitted with the same connecting block. Both ends of the connecting block have circular holes adapted to the sliding rods. Springs are fitted to one end of each sliding rod located between the connecting block and the fixing block.

[0007] The working principle of this utility model is as follows: by setting up four feeding mechanisms, materials can be placed inside the four conical unloading boxes, and materials can be added automatically as needed.

[0008] The feeding mechanism also includes a movable plate fixedly connected to the bottom of the connecting block. The movable plate has a square opening at the discharge port of the conical unloading box, and a feeding frame is fixedly connected to the bottom of the movable plate at the square opening. The bottom of the feeding frame is in contact with the U-shaped baffle.

[0009] Using the above structure, the material is continuously fed to the feeding frame under the action of gravity through the reciprocating movement of the moving plate and the feeding frame, thereby realizing the feeding.

[0010] The feeding mechanism also includes two push rods fixedly connected to the side of the moving plate near the edge of the feeding box. Both push rods slide through the feeding box and are fixedly connected to the same arc-shaped block. The outer wall of the feeding box has a round hole that matches the push rods, and the top of the arc-shaped block has an arc-shaped groove.

[0011] By adopting the above structure, the setting of arc-shaped blocks and arc-shaped grooves, together with the first servo motor and L-shaped rod, the material can be added to the inside of the conical unloading box;

[0012] A second servo motor is fixedly connected to the middle of the top of the inner side of the feeding box, and a Z-shaped plate is fixedly connected to the top output end of the second servo motor through the feeding box.

[0013] The top of the other end of the Z-shaped plate is fixedly connected to a first servo motor. The bottom output end of the first servo motor passes through the Z-shaped plate and is fixedly connected to an L-shaped rod. One end of the bottom of the L-shaped rod is adapted to four arc-shaped blocks.

[0014] Using the above structure, the L-shaped rod rotates in the arc groove, causing the moving plate to move back and forth, thereby realizing the addition of materials to the feeding frame.

[0015] The outer wall of the feeding box is equipped with a controller, which is electrically connected to the first servo motor and the second servo motor respectively.

[0016] Using the above structure, the controller controls the first and second servo motors, enabling automatic control of material addition to the four conical unloading boxes.

[0017] Compared with the prior art, the automatic plastic powder dispensing device of this utility model has the following advantages:

[0018] In this invention, by employing four feeding mechanisms and a first servo motor and a second servo motor, the rotation of the second servo motor controls the first servo motor to reach the designated conical unloading box. The intermittent, slow rotation of the first servo motor allows the feeding frame to quantitatively feed material into the conical unloading box. Simultaneously, by controlling the number of rotations of the first servo motor, the amount of material fed can be controlled, effectively solving the problem in the prior art that only one material can be fed at a time. This achieves full-process automation, significantly improves batching efficiency, reduces manual intervention, lowers labor costs and the risk of human error, and allows for quantitative feeding of multiple materials, improving the adaptability of the device.

Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-5 As shown, an automatic plastic powder dispensing device includes a feeding box 1 with a feeding port at the bottom. Four feeding mechanisms 2 are evenly spaced around the top circumference of the feeding box 1. Each feeding mechanism 2 includes a conical unloading box 201 fixedly embedded on one side of the top of the feeding box 1. The top of the feeding box 1 has a rectangular opening adapted to the conical unloading box 201. A U-shaped baffle 202 is fixedly connected to the bottom of the conical unloading box 201. The outer side of the conical unloading box 201 is away from the center of the feeding box 1. A fixing block 204 is fixedly connected to one side of the feeding box 1. Two sliding rods 207 are fixedly connected to the side of the fixing block 204 near the edge of the feeding box 1. The other end of the two sliding rods 207 is fixedly connected to the same limiting plate 210. The same connecting block 206 is slidably sleeved on the circumferential surface of the two sliding rods 207. Both ends of the connecting block 206 are provided with round holes that are adapted to the sliding rods 207. Springs 208 are sleeved on one end of the two sliding rods 207 located between the connecting block 206 and the fixing block 204.

[0027] In this utility model, the feeding mechanism 2 also includes a movable plate 203 fixedly connected to the bottom of the connecting block 206. The movable plate 203 has a square opening at the discharge port of the conical unloading box 201, and a feeding frame 209 is fixedly connected to the bottom of the movable plate 203 at the square opening. The bottom of the feeding frame 209 is in contact with the U-shaped baffle 202.

[0028] In this utility model, the feeding mechanism 2 also includes two push rods 211 fixedly connected to the side of the moving plate 203 near the edge of the feeding box 1. Both push rods 211 slide through the feeding box 1 and are fixedly connected to the same arc-shaped block 212. The outer wall of the feeding box 1 is provided with a round hole that matches the push rods 211, and the top of the arc-shaped block 212 is provided with an arc-shaped groove 213.

[0029] In this utility model, a second servo motor 4 is fixedly connected to the middle of the top of the inner side of the feeding box 1, and a Z-shaped plate 3 is fixedly connected to the top output end of the second servo motor 4 through the feeding box 1.

[0030] In this utility model, a first servo motor 301 is fixedly connected to the top of the other end of the Z-shaped plate 3, and an L-shaped rod 302 is fixedly connected to the bottom output end of the first servo motor 301 through the Z-shaped plate 3.

[0031] In this invention, one end of the bottom of the L-shaped rod 302 is adapted to four arc-shaped blocks 212.

[0032] In this utility model, a controller is provided on the outer wall of the feeding box 1, and the controller is electrically connected to the first servo motor 301 and the second servo motor 4 respectively.

[0033] The working principle of this utility model is as follows: The feeding box 1 is installed on top of the device that needs to be fed. The plastic materials to be added are placed into the corresponding conical unloading boxes 201. When material needs to be added to a conical unloading box 201, the second servo motor 4 is started, so that the Z-shaped plate 3 moves with the first servo motor 301 to the arc-shaped block 212 on the outside of the conical unloading box 201. The L-shaped rod 302 stops on one side of the feeding box 1 each time. When the first servo motor 301 moves into the arc groove 213 of each arc block 212, the bottom of the L-shaped rod 302 can slide smoothly into the corresponding arc groove 213. Then the first servo motor 301 is started, so that the first servo motor 301 rotates slowly and intermittently, rotating half a turn each time, and the number of rotations is even. Each time the L-shaped rod 302 rotates, it pushes... The movement of the arc-shaped block 212, push rod 211, and moving plate 203 causes the spring 208 to be crushed. At the same time, the feeding frame 209 leaves the U-shaped baffle 202, and the material in the feeding frame 209 automatically falls into the feeding box 1 and enters the processing device. Meanwhile, the moving plate 203 blocks the bottom of the conical unloading box 201, preventing the material from falling. After rotating half a turn again, the feeding frame 209 returns to its original position. At this time, under the action of gravity, the feeding frame 209 is filled again. The required amount is added by the number of times the feeding frame 209 moves back and forth. At the same time, the second servo motor 4 controls the Z-shaped plate 3 to rotate to different arc-shaped grooves 213 on the outside of the conical unloading box 201, so that multiple materials can be quantitatively added. At the same time, the second servo motor 4 will not drive the Z-shaped plate 3 to rotate in one direction continuously, but will only perform a reciprocating rotation within one circumference.

[0034] In summary, in this utility model, the cooperation between the second servo motor 4 and the first servo motor 301 enables the quantitative addition of materials to the four conical unloading boxes 201, which is convenient to control and ensures accurate material addition.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
