[0002] PVC pipe metering and feeding equipment is a device used to accurately control the amount of raw materials supplied during the production process of PVC (polyvinyl chloride) pipes. In PVC pipe manufacturing, accurate raw material metering is a key factor in ensuring product quality and stable performance. It can ensure that the amount of PVC raw materials put into production each time meets the set process requirements, thereby manufacturing pipes with consistent specifications.

[0003] However, the prior art still has the following problems:

[0004] Most of the existing PVC pipe metering and feeding equipment cannot ensure continuous feeding and accurate metering. Some traditional feeding devices rely on gravity to feed materials. However, when the raw materials are unevenly piled in the silo or bridging occurs, the raw materials will not fall smoothly, affecting the continuity of feeding. Some simple metering equipment may only perform rough measurement through volumetric methods or weighing sensors, which cannot meet high-precision metering requirements. When producing high-end PVC pipes with strict requirements on raw material ratios, this metering error may lead to a decline in product quality.

[0018] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0019] Example 1

[0020] A PVC pipe metering feeding equipment, refer to Figure 1-4 , including a storage bin 1, a feed hopper 11 is provided at the upper end of the storage bin 1, a discharge pipe 12 is fixedly provided at the lower end of the storage bin 1, and a support plate 2 is provided below the storage bin 1, a guard plate 21 is fixedly provided on one side of the upper end of the support plate 2, a motor 22 is provided at the lower end of the guard plate 21, the output end of the motor 22 passes through the guard plate 21 and is fixed with a rotating plate 23, the lower end of the rotating plate 23 is rotatably connected to the guard plate 21, a connecting block 24 is rotatably provided on one side of the upper end of the rotating plate 23, and a connecting rod is rotatably provided at one end of the connecting block 24 25, one end of the connecting rod 25 is provided with a movable plate 27, and both sides of the upper end of the support plate 2 are fixed with limit plates 29, and the two ends of the movable plate 27 are respectively slidably connected with the two limit plates 29, and one end of the connecting rod 25 is rotatably provided with a rotating block 26, one end of the rotating block 26 is fixedly connected to the movable plate 27, and the lower end of the movable plate 27 is embedded with a quantitative bucket 210, the upper end of the quantitative bucket 210 is at the same height as the upper end of the movable plate 27, and the upper end of the movable plate 27 is movable with the lower end of the discharge pipe 12 When the feed container 21 is in contact with the feed container 21, the motor 22 on the guard plate 21 is working, and its output end drives the rotating plate 23 to rotate. During the rotation of the rotating plate 23, the movable plate 27 is driven to make a reciprocating linear motion through the connection of the connecting block 24, the connecting rod 25, and the rotating block 26. The limit plate 29 improves the stability of the movement of the movable plate 27. When the movable plate 27 moves in the direction close to the storage bin 1, the upper end of the movable plate 27 contacts the lower end of the discharge pipe 12. When the quantitative bucket 210 is connected to the discharge pipe 12, the raw material falls from the discharge pipe 12 into the quantitative bucket 210 on the movable plate 27. Since the upper end of the quantitative bucket 210 is at the same height as the upper end of the movable plate 27, and the movable plate 27 is in active contact with the lower end of the discharge pipe 12, it can ensure that a certain amount of raw material is accurately filled into the quantitative bucket 210. If different amounts need to be put into the quantitative bucket 210 at one time, it is only necessary to adjust the output speed of the motor 22. The reciprocating motion of the movable plate 27 driven by the motor 22 realizes continuous quantitative feeding operation, thereby improving production efficiency.

[0021] Reference Figure 1-4 The upper end of the support plate 211 is fixed with a discharge hopper 212 on one side of the lower end of the support plate 2. When the movable plate 27 moves in the direction away from the storage bin 1, the quantitative hopper 210 moves accordingly. When the quantitative hopper 210 moves to the position on the side of the plate 211, one end of the plate 211 contacts the cover 214, and the cover 214 slowly opens under the gravity of the raw material, so that the lower side of the quantitative hopper 210 opens, and the raw material falls into the discharge hopper 212 below, completing the quantitative feeding process. Through the cooperation of the quantitative hopper 210 and the movable plate 27, a certain amount of PVC raw material can be accurately obtained, ensuring the accuracy of each feeding, which is conducive to the production of PVC pipes with stable quality.

[0022] The implementation principle of the embodiment of the present application is as follows: when the motor 22 on the guard plate 21 is working, its output end drives the rotating plate 23 to rotate. During the rotation of the rotating plate 23, the movable plate 27 is driven to perform reciprocating linear motion through the connection of the connecting block 24, the connecting rod 25, and the rotating block 26. The limit plate 29 improves the stability of the movement of the movable plate 27. When the movable plate 27 moves in the direction close to the storage bin 1, the upper end of the movable plate 27 contacts the lower end of the discharge pipe 12. When the quantitative bucket 210 is connected to the discharge pipe 12, the raw materials fall from the discharge pipe 12 into the quantitative bucket 210 on the movable plate 27. Since the upper end of the quantitative bucket 210 is at the same height as the upper end of the movable plate 27, and the movable plate 27 is in active contact with the lower end of the discharge pipe 12, it can ensure that a certain amount of raw materials is accurately filled into the quantitative bucket 210. If different amounts need to be put into the quantitative bucket 210 at one time, it is only necessary to adjust the output speed of the motor 22. The reciprocating motion of the movable plate 27 driven by the motor 22 realizes continuous quantitative feeding operation, thereby improving production efficiency.

[0023] When the movable plate 27 moves away from the storage bin 1, the metering hopper 210 moves accordingly. When the metering hopper 210 moves to a position on the side of the abutment plate 211, one end of the abutment plate 211 contacts the cover plate 214. The cover plate 214 slowly opens under the gravity of the raw materials, causing the lower side of the metering hopper 210 to open, and the raw materials fall into the discharge hopper 212 below, completing the quantitative feeding process. Through the cooperation of the metering hopper 210 and the movable plate 27, a certain amount of PVC raw materials can be accurately obtained, ensuring the accuracy of each feeding, which is conducive to the production of PVC pipes with stable quality.

[0024] Example 2

[0025] The difference between this embodiment and embodiment 1 is that:

[0026] Reference Figure 5 The rubber pad 32 on the contact arc plate 31 contacts the discharge pipe 12 and impacts the discharge pipe 12, thereby assisting the raw materials to be discharged smoothly from the discharge pipe 12, and ensuring the continuity of the feeding. The rubber pad 32 plays the role of buffering and increasing friction, which can not only protect the discharge pipe 12 but also better push the raw materials, effectively solving the problem that the raw materials may be blocked at the discharge pipe 12 of the storage bin 1, further ensuring the continuity of the feeding, reducing the production stagnation time caused by the interruption of feeding, and reducing the production cost.

[0027] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
