Description

Technical Field

[0001] This utility model relates to the technical field of enamel glaze feeding machines, and in particular to a pressure-distributing device for an enamel glaze feeding machine. Background Technology

[0002] In the production process of enamel glaze, the stable operation of the enamel glaze feeder is crucial. Traditional enamel glaze feeders have many problems in the material conveying stage.

[0003] When conveying enamel glaze raw materials, the material is transported by a screw conveyor roller driven by a motor. Due to variations in material characteristics and conveying volume, friction and compression occur between the material and the inner wall of the conveying pipe as it flows through the pipe, and the impact force of the material flow is also significant. When the conveying volume is normal, the conveying system can maintain stable operation. However, if there is an excess of material, the pressure on the inner wall of the conveying pipe will increase dramatically.

[0004] Excessive pressure can damage the conveying pipe itself, such as causing increased wear, cracks, or even rupture, affecting the service life of the equipment. It can also negatively affect the spiral conveying roller and the spiral shaft connected to it, making their working condition unstable. This may cause problems such as motor overload and increased equipment vibration. In severe cases, it may even cause the entire conveying system to shut down, thereby affecting the production progress of enamel glaze and increasing production costs. Utility Model Content

[0005] The purpose of this invention is to provide a pressure-dividing device for an enamel glaze feeder, which solves the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pressure-dividing device for an enamel glaze feeder, comprising a feeding pipe, a hopper, and a spiral feeding roller. The hopper is fixed at the rear end of the top of the feeding pipe, and a motor is installed at the rear end of the feeding pipe. The rotating shaft at the front end of the motor extends into the rear end of the feeding pipe. A spiral feeding roller is rotatably arranged inside the feeding pipe. The rear end of the spiral feeding roller is fixedly connected to the rotating shaft at the front end of the motor. An outer shell is provided on the outer periphery of the front end of the feeding pipe, and a pressure-dividing component is provided inside the outer shell.

[0007] Preferably, the pressure-distributing assembly includes an internal pressure plate disposed inside the outer shell, pressure-distributing airbags installed at both ends inside the outer shell, the pressure-distributing airbags being located at one end of the internal pressure plate, retraction grooves being equally spaced at the front end of the inner sidewall of the conveying pipe, pressure-distributing blocks being disposed in the retraction grooves, the pressure-distributing blocks protruding from the inner sidewall of the conveying pipe, a connecting rod being fixed to the back of the pressure-distributing blocks, the connecting rod extending into the interior of the outer shell and being fixedly connected to the internal pressure plate.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. The present invention provides a pressure-distributing device for an enamel glaze feeder. When excessive material causes excessive pressure on the inner wall of the conveying pipe, the pressure-distributing block and the pressure-distributing airbag work together. The pressure-distributing airbag generates a reverse elastic force, which acts on the material and the conveying pipe through the pressure-distributing block, effectively offsetting part of the pressure of the material on the inner wall of the conveying pipe, reducing the overall pressure load on the conveying pipe, and ensuring the stable operation of the conveying pipe.

[0010] 2. The pressure-distributing device for an enamel glaze feeder provided by this utility model has an elastic deformation characteristic in its pressure-distributing airbag, which can absorb and buffer the impact force caused by sudden pressure changes in the material. When the material pressure increases instantaneously, it quickly deforms to relieve the force, protecting the conveying pipe and the spiral conveying roller, reducing the risk of equipment damage due to impact, and extending the service life of the equipment.

[0011] 3. The pressure-distributing device for an enamel glaze feeder provided by this utility model uses the deformation of the pressure-distributing airbag to promote a more uniform pressure distribution on the inner wall of the conveying pipe, avoiding excessively high local pressure caused by uneven material accumulation. This prevents damage such as wear and breakage of the equipment due to abnormal local pressure, ensuring the long-term stable and efficient operation of the entire conveying system.

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.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figures 1 to 5 As shown, the present invention discloses a pressure-dividing device for an enamel glaze feeder, comprising a feeding pipe 1, a hopper 2, and a spiral feeding roller 4. The hopper 2 is fixed to the rear end of the top of the feeding pipe 1. A motor 3 is installed at the rear end of the feeding pipe 1. The rotating shaft at the front end of the motor 3 extends into the rear end of the feeding pipe 1. The spiral feeding roller 4 is rotatably arranged inside the feeding pipe 1. The rear end of the spiral feeding roller 4 is fixedly connected to the rotating shaft at the front end of the motor 3. An outer shell 5 is provided on the outer periphery of the front end of the feeding pipe 1. A pressure-dividing component is provided inside the outer shell 5.

[0021] The pressure-dividing assembly includes an internal pressure plate 51 disposed inside the outer shell 5. Pressure-dividing airbags 52 are installed at both ends inside the outer shell 5. The pressure-dividing airbags 52 are located at one end of the internal pressure plate 51. Retraction grooves 55 are evenly spaced at the front end of the inner sidewall of the feed pipe 1. Pressure-dividing blocks 53 are disposed in the retraction grooves 55. The pressure-dividing blocks 53 protrude from the inner sidewall of the feed pipe 1. A connecting rod 54 is fixed to the back of the pressure-dividing blocks 53. The connecting rod 54 extends into the interior of the outer shell 5 and is fixedly connected to the internal pressure plate 51.

[0022] Specifically, in the enamel glaze production process, the enamel glaze raw material is poured into the hopper 2. As the raw material is poured in, it enters the internal space of the conveying pipe 1. At this time, the motor 3 connected to one end of the conveying pipe 1 starts operating. The motor 3 is connected to the spiral conveying roller 4 via a rotating shaft. When the motor 3 starts, it drives the spiral conveying roller 4 to rotate at high speed. During the continuous and stable rotation of the spiral conveying roller 4, its spiral blades continuously push the enamel glaze raw material, causing it to be conveyed forward along the axial direction of the conveying pipe 1.

[0023] During this conveying process, the material inevitably comes into close contact with the inner wall of the conveying pipe 1 due to the continuous pushing of the blades of the screw conveyor roller 4, resulting in friction and compression. This friction and compression creates pressure on the inner wall of the conveying pipe 1. At the same time, the material's kinetic energy is converted into impact force on the inner wall during its flow, further increasing the pressure on the inner wall of the conveying pipe 1.

[0024] A pressure-distributing block 53 is installed at the front end of the inner wall of the conveying pipe 1. When the conveying rate of the enamel glaze raw material is at a normal level, the accumulation of material in the conveying pipe 1 is moderate, and the pressure on the conveying pipe 1 and the spiral conveying roller 4 is relatively small. At this time, the pressure-distributing block 53 and its matching pressure-distributing airbag 52 are basically in a naturally extended state. The pressure-distributing airbag 52 is not subjected to significant external squeezing force, and the internal gas pressure is stable. Under these conditions, the spiral conveying roller 4 can easily and smoothly push the material to continuously convey the material. The entire conveying system operates smoothly and orderly, the cooperation between various components is tacit, and noise and vibration are controlled at a low level.

[0025] However, in the event of an abnormal excess of material, a large amount of material rushes into the conveying pipe 1, causing a significant increase in the material's bulk density. This accumulated material exerts a much stronger pressure on the inner wall of the conveying pipe 1 than normal. As the pressure gradually increases, the pressure-distributing block 53 is the first to be affected, as it is tightly compressed by the material. Under the strong compressive force, the pressure-distributing block 53 begins to displace, which in turn moves the connected internal pressure plate 51. The internal pressure plate 51 acts as a force transmitter, accurately transferring the compressive force on the pressure-distributing block 53 to the downstream pressure-distributing airbag 52.

[0026] When the pressure-distributing airbag 52 receives the compressive force transmitted from the built-in pressure plate 51, its internal structure undergoes significant deformation. The material of the pressure-distributing airbag 52 typically possesses good elasticity; when subjected to external pressure, it generates an elastic force completely opposite to the direction of the compressive force, according to the laws of force action. Based on the fundamental physical principle that forces act in pairs, this elastic force generated by the pressure-distributing airbag 52 acts again on the material and the conveying pipe 1 through the pressure-distributing block 53. In this process, the elastic force successfully offsets a portion of the pressure exerted by the material on the inner wall of the conveying pipe 1, effectively reducing the peak pressure on the conveying pipe 1 and achieving the important purpose of pressure distribution in the conveying pipe 1.

[0027] Furthermore, due to the elastic deformation characteristics of the pressure-distributing airbag 52, it can flexibly adapt to dynamic changes in material pressure within a certain range. When the material pressure suddenly increases, the pressure-distributing airbag 52 deforms rapidly, absorbing and buffering some of the impact force; when the material pressure decreases, the pressure-distributing airbag 52 can gradually return to its original shape, continuously maintaining its protective function on the conveying pipe 1. This buffering and shock-absorbing function is like putting a layer of "protective armor" on the conveying pipe 1 and the spiral conveying roller 4, protecting them from direct damage caused by excessive impact force due to sudden changes in material pressure, greatly extending the service life of the equipment. In addition, during the deformation process, the pressure-distributing airbag 52 can also promote a more uniform distribution of pressure on the inner wall of the conveying pipe 1. The situation of excessive local pressure that might have occurred due to uneven material accumulation is effectively improved by the action of the pressure-distributing airbag 52, avoiding equipment damage caused by excessive local pressure, and ensuring that the conveying system can operate stably and efficiently for a long time.
