Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of material feeding equipment, and in particular relates to a PVC pipe processing anti-blocking uniform material feeding device. Background Art
[0002] The main material of PVC pipes is polyvinyl chloride. Generally, the production process of PVC pipes is to mix PVC resin, stabilizer, lubricant, colorant, and filler, and then add them to the extruder hopper after vacuum conveying. While heating, the raw material is pushed forward and extruded by the rotation of the screw, so that it gradually becomes a molten plastic belt and enters the die head to extrude a soft tubular product. Then, it goes through a series of processes such as vacuum sizing, spray cooling, spray marking, traction cutting, and expansion to make the pipe. In actual production activities, according to the actual performance requirements, manufacturers will add a specified proportion of calcium carbonate powder to the raw materials according to national standards to produce PVC high-calcium pipes with low cost but meeting performance requirements.
[0003] Existing PVC high calcium pipe extrusion molding feeding generally adopts the screw feeding mode of traditional PVC pipes. Screw feeding is to feed the raw materials by squeezing and rotating the screw. It was found in the production process that due to the addition of calcium carbonate, the extrusion molding feeding process of PVC high calcium pipe is more prone to raw material agglomeration, accumulation, and finally extrusion blockage, which leads to uneven feeding of the feeding device or even jamming and shutdown, seriously affecting production efficiency and causing great economic losses.
[0004] Therefore, in view of the above problems, the present application proposes a PVC pipe processing anti-blocking uniform feeding device that can effectively solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a PVC pipe processing anti-blocking uniform feeding device in view of the deficiencies of the prior art, thereby effectively solving the problems existing in the prior art.
[0006] To achieve the above purpose, the specific technical solution of the utility model is as follows:
[0007] A PVC pipe processing anti-blocking uniform feeding device comprises an extrusion molding device, a feeding port is arranged at the left end of the extrusion molding device, a storage bin is arranged above the feeding port, a first material storage device is connected to the lower end of the storage bin, a stirring device is arranged between the storage bin and the first material storage device, a vibration device is connected to the lower end of the first material storage device, a conveying device is connected to the center of the vibration device in a vertically downward rotation, the first material storage device is connected to the feeding port through a conveying pipe, a second material storage device is arranged at the lower end of the conveying pipe near the feeding port, and the second material storage device is rotatably connected to the conveying device.
[0008] As a further configuration of the above solution, the first material storage device includes a first material storage bin, and a first feed channel is arranged on an upper end surface of the first material storage bin, and the first feed channel is connected to the material storage bin.
[0009] As a further configuration of the above scheme, the stirring device includes a stirring shaft, which is rotatably connected to the first feed channel, the stirring shaft is perpendicular to the axis of the feed channel, and the stirring shaft is provided with radially uniformly divergent disturbance columns. The stirring shaft is connected to a driving motor, and the driving motor drives the stirring shaft to rotate. The disturbance columns transport the raw materials in the storage bin to the first storage bin, and at the same time preliminarily break up the lumps in the raw materials.
[0010] As a further arrangement of the above scheme, the vibration device is fixedly installed at the lower end of the first material storage device, and the vibration device includes a leakage tray, which is provided with evenly distributed leakage holes, a vibration motor is provided at the center of the upper end surface of the leakage tray, and a mounting flange is provided on the lower end surface of the leakage tray, and the mounting flange is connected to the vibration motor.
[0011] As a further configuration of the above scheme, the conveying device includes an auger device, which is located in the transport pipe and coaxial with the transport pipe, and the auger device is rotatably connected to the mounting flange. A feed tray device is arranged at the upper end of the auger device, and the feed tray device includes a mounting table, and the mounting table is fixedly mounted on the auger device. A connecting column is vertically arranged on the upper end surface of the mounting table, and a feed tray is fixedly connected to the upper end of the connecting column. The feed tray is provided with feed holes, and the feed holes correspond to the leakage holes one by one. A pressure scraper is fixedly connected to the lower end of the auger device.
[0012] As a further arrangement of the above scheme, the second material storage device includes a second material storage bin, which is fixedly mounted at the lower end of the conveying pipe. A spoke mounting platform is provided at the upper end of the second material storage bin, which is rotatably connected to the auger device, and the spoke mounting platform ensures the verticality and operating stability of the auger device.
[0013] The working principle of the utility model: during production, the mixed raw materials are stored in the storage bin, and the raw materials will inevitably clump to a certain extent. When the device is unloading, the driving motor is started to drive the stirring shaft to rotate, and the disturbance column transports the raw materials in the storage bin to the first storage bin, and the clumps in the raw materials are initially broken. After the raw materials fall into the first storage bin, the vibration motor is started, and the vibration motor drives the auger device to rotate while vibrating, and the unloading plate rotates synchronously. When the unloading hole overlaps with the leakage hole, the raw materials pass through the leakage plate and the unloading plate into the conveying pipeline. Since the leakage plate also vibrates synchronously, the clumps in the raw materials are further chopped and shattered when passing through the leakage plate and the unloading plate, and the amount of raw materials can be controlled by the speed of the unloading plate, which is conducive to accurate unloading. When the raw materials enter the conveying pipeline and contact the auger device, they are in a uniform state. The auger device rotates to transport the raw materials downward to the second storage bin, and the material pressing scraper rotates synchronously with the auger device to compact the raw materials uniformly, ensuring that the raw materials enter the feed port uniformly and continuously.
[0014] The utility model has the following beneficial effects:
[0015] By setting a stirring device between the storage bin and the first material storage device, in conjunction with a vibration device and a conveying device, the raw materials are evenly and continuously conveyed to the second material storage device. After the raw materials are compacted in the second material storage device, they are conveyed to the feed port of the extrusion molding device, thereby achieving uniform material discharge, solving the problem of material discharge blockage, and greatly improving production efficiency.
