Description

Technical Field

[0001] This utility model relates to the field of plastic pipe production technology, specifically to a raw material metering device for plastic pipe production. Background Technology

[0002] Plastic pipes are piping systems made from synthetic resin as the main raw material, with the addition of appropriate additives, and produced through processes such as extrusion molding. They have been widely used in various fields such as construction, municipal engineering, industry, and agriculture, and have largely replaced traditional metal pipes and cement pipes. In order to ensure the molding quality of plastic pipes and reduce raw material waste during the production process, it is necessary to weigh the raw material particles quantitatively.

[0003] However, existing metering devices typically pour raw material particles directly into the weighing bin for weighing. This makes it difficult to buffer and weaken the impact force generated by the falling raw material. A certain weight of raw material particles falling directly into the weighing bin can easily cause a large impact force on the weighing bin due to the weight of the raw material itself, which can easily cause large fluctuations in the weighing data, thereby affecting the stability of the raw material weighing and reducing the accuracy of the raw material measurement. Utility Model Content

[0004] The purpose of this invention is to provide a raw material metering device for plastic pipe production. Through the structural design of the impact-resistant components, it can effectively buffer and weaken the impact force generated by the symmetrical metering chamber during the raw material injection process, thus solving the problem of difficulty in buffering and weakening the impact force generated by the falling raw material.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a raw material metering device for plastic pipe production, comprising a base and an impact-resistant assembly. A U-shaped frame is provided on the base, and two receiving slots, namely, a first receiving slot and a second receiving slot, are provided on the inner bottom sides of both ends of the U-shaped frame. Two impact-resistant assemblies are provided, each comprising a support plate and two uprights. Weighing chambers are provided on the two support plates. The uprights are vertically installed in the first receiving slot, and a movable sleeve is fitted on the top outer surface of the upright. The side of the movable sleeve is connected to one side of the support plate. A damper is provided in the second receiving slot, and the extended end of the damper is connected to one side of the support plate.

[0007] Furthermore, a connecting block is provided on the side of the movable sleeve, which mates with the receiving groove and passes through the receiving groove to connect with one side of the support plate.

[0008] Furthermore, the extended end of the damper is provided with a mounting block, one end of which is connected to one side of the support plate.

[0009] Furthermore, support rods are installed at the four corners of the weighing chamber, and weighing sensors are installed at the bottom of the support rods. The weighing sensors are installed on the surface of the support plate.

[0010] Furthermore, a fixed plate is provided on one side of the bottom of the weighing chamber, and two reinforcing rods are provided on the fixed plate. The top of the reinforcing rods is connected to the surface of the weighing chamber. Two electric push rods are rotatably installed at the bottom of the fixed plate. A rectangular through groove is opened on the bottom side of the weighing chamber, and a gate is rotatably installed in the rectangular through groove. The output ends of the two electric push rods are rotatably connected to the surface of the gate. A discharge hopper is provided directly below the rectangular through groove.

[0011] Furthermore, a feed hopper is embedded in the top of the U-shaped frame, and the bottom end of the feed hopper passes through the top of the U-shaped frame to directly above the weighing chamber.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the structural design of the impact-resistant component, utilizes the compression and contraction of two springs and the compression and retraction of the damper's extended end to significantly weaken the impact force of falling raw materials on the weighing chamber. This allows the weighing chamber to move smoothly downward within the U-shaped frame as raw materials are continuously added during the feeding and weighing process. This effectively buffers and weakens the impact force generated by the symmetrical weighing chamber during raw material injection, reduces the fluctuation range of weighing data during raw material measurement, improves the stability of raw material measurement and weighing, and ensures the accuracy of raw material weighing.

[0014] 2. This utility model, through the structural design of electric push rods, gate, and rectangular through groove, uses the output ends of two electric push rods to synchronously drive the gate to rotate within the rectangular through groove, so that the discharge gap between the gate and the rectangular through groove is fully opened, realizing the rapid discharge of the weighed quantitative raw materials. This allows for convenient adjustment of the discharge gap, ensuring that the raw materials can be quickly poured out from the weighing bin after weighing, improving the speed of conveying quantitative materials to the next process, and ensuring the production efficiency of plastic pipes.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a raw material metering device for plastic pipe production, including a base 1 and an impact-resistant component 4. A U-shaped frame 2 is provided on the base 1, and two receiving grooves 201 and 202 are provided on the inner bottom sides of both ends of the U-shaped frame 2.

[0023] Two impact-resistant components 4 are provided, each including a support plate 401 and two uprights 402. Weighing chambers 3 are mounted on the two support plates 401. A feed hopper 203 is embedded in the top of the U-shaped frame 2, with its bottom end passing through the top of the U-shaped frame 2 and extending directly above the weighing chamber 3. Raw materials can be poured into the weighing chamber 3 through the feed hopper 203. Support rods 305 are provided at each of the four corners of the weighing chamber 3, with weighing sensors 306 mounted at the bottom of each support rod 305. The weighing sensors 306 are mounted on the surface of the support plates 401, facilitating quantitative weighing of the raw materials in the weighing chamber 3. All four weighing sensors 306 are externally connected to a PLC controller and a display screen. The uprights 402 are vertically mounted on the weighing chamber. Inside the first trough 201, a movable sleeve 403 is fitted on the top outer surface of the upright 402. The side of the movable sleeve 403 is connected to one side of the support plate 401. A connecting block is provided on the side of the movable sleeve 403. The connecting block is fitted with the first trough 201 and passes through the first trough 201 to connect to one side of the support plate 401, which can facilitate the fixed connection between the movable sleeve 403 and the support plate 401. A damper 405 is provided inside the second trough 202. The protruding end of the damper 405 is connected to one side of the support plate 401. An installation block 406 is provided on the protruding end of the damper 405. One end of the installation block 406 is connected to one side of the support plate 401, which can facilitate the connection between the protruding end of the damper 405 and the support plate 401.

[0024] In use, when raw material particles are poured into the weighing chamber 3 through the feed hopper 203, due to their own weight, the particles fall into the weighing chamber 3, generating a downward impact force. This impact force is transmitted to the two corresponding support plates 401 through two pairs of support rods 305. This causes the support plates 401 to exert a downward compressive force on the two movable sleeves 403 and mounting blocks 406 connected to their sides. Consequently, the two movable sleeves 403 slide on the surface of the corresponding uprights 402 and compress the springs 404. After being compressed on the outer surface of the upright 402, the spring 404 gradually contracts, causing the mounting block 406 to press down on the protruding end of the damper 405, causing the protruding end of the damper 405 to retract. Through the compression and contraction of the two springs 404 and the compression and retraction of the protruding end of the damper 405, the impact force of the falling raw material on the weighing chamber 3 is greatly weakened. As the raw material is continuously added during the feeding and weighing process, the weighing chamber 3 moves smoothly downward within the U-shaped frame 2, thereby effectively buffering and weakening the impact force on the weighing chamber 3.

[0025] A fixing plate 301 is provided on one side of the bottom of the weighing chamber 3. Two reinforcing rods are provided on the fixing plate 301 to ensure the installation stability of the fixing plate 301. The top of the reinforcing rods is connected to the surface of the weighing chamber 3. Two electric push rods 302 are rotatably installed on the bottom of the fixing plate 301. Both ends of the electric push rods 302 are rotatably fitted with V-shaped brackets. The two V-shaped brackets are fixedly connected to the bottom of the fixing plate 301 and the surface of the gate plate 303, respectively. A rectangular through groove 304 is opened on the bottom side of the weighing chamber 3. The gate plate 303 is rotatably installed in the rectangular through groove 304. The output ends of the two electric push rods 302 are rotatably connected to the surface of the gate plate 303. A discharge hopper 307 is provided directly below the rectangular through groove 304.

[0026] After a fixed amount of raw material is injected into the weighing chamber 3 through the feeding hopper 203, it is weighed by four weighing sensors 306 in conjunction with an external PLC controller. The weighing data is displayed on an external display screen. Then, the external PLC controller synchronously controls the two electric push rods 302 at the bottom of the fixed plate 301 to start, so that the output ends of the two electric push rods 302 synchronously push the gate 303 to rotate in the rectangular channel 304. This causes the rectangular channel 304 to gradually rotate outward and open, so that the discharge gap between the gate 303 and the rectangular channel 304 is fully opened. The raw material weighed in the weighing chamber 3 flows into the discharge hopper 307 through the discharge gap, and then falls into the storage container placed in advance below the discharge hopper 307. This achieves rapid discharge of the weighed raw material.
