Description

Technical Field

[0001] The utility model relates to the field of brush wire feeding processing, in particular to a screw extruder for brush wire processing with a feeding drying structure. Background Art

[0002] During the preparation process, the brush filament raw materials need to be formed by a screw extruder. However, there is a potential problem in this process: if the brush filament raw materials are not properly handled during storage or transportation, they can easily absorb moisture from the air. This moisture will be converted from liquid to water vapor during the subsequent extrusion process. The formation of water vapor not only changes the physical properties of the raw materials, but may also form channels inside the sheet. These channels will destroy the uniformity and structural integrity of the raw materials, further affecting the performance and quality of the extruded products.

[0003] Therefore, it is necessary to propose a screw extruder for brush wire processing with a feeding and drying structure to solve the above problems. Utility Model Content

The formation of water vapor not only changes the physical properties of the raw materials, but may also form channels inside the plate. These channels will destroy the uniformity and structural integrity of the raw materials, further affecting the performance and quality of the extruded products.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 - Figure 5 As shown, the utility model provides a screw extrusion device for brush filament processing with a feeding and drying structure, comprising a screw extruder 1, a feed end 2 and a discharge end 3. The screw extruder 1 is used to extrude the brush filaments, and the feed end 2 is responsible for conveying the materials from the feed end 2, and the discharge end 3 is provided with a connecting pipe, so that the extruded brush filaments can be quickly and conveniently connected to other equipment or systems.

[0021] The lower end of the feed end 2 is provided with a drying component 4 for drying the material, which is mainly used to dry the material immediately after feeding. The excess moisture of the material is removed before entering the screw extruder 1, thereby avoiding the problem of channel formation due to the conversion of moisture into water vapor during the extrusion process;

[0022] The drying assembly 4 includes a drying box 401. The inner wall of the drying box 401 is provided with exhaust holes for discharging excess hot air. The drying box 401 is arranged on the surface of the screw extruder 1. The inner wall of the drying box 401 has a plurality of drop plates 402 arranged at equal distances. The drop plates 402 are arranged in an inclined manner. The bottoms of the drop plates 402 are provided with heating plates 405. Drop grooves 5 are provided on the surfaces of the drop plates 402. The inclined drop plates 402 ensure that the materials can flow downward more evenly, effectively avoiding the accumulation of materials during the drying process. In addition, the drop plates 402 adopt a configuration of one long and one short, which prolongs the residence time of the materials on the drop plates 402, thereby improving the drying effect. When the heating plates 405 are started, the drop grooves 5 are in close contact with the heating plates 405, making the materials more susceptible to the influence of temperature, further improving the drying efficiency.

[0023] The drying box 401 is connected to the screw extruder 1. The inner wall of the drying box 401 is provided with a diverter plate 404. The diverter plate 404 is provided with a plurality of drip holes 406 which are arranged at equal distances. The inner wall of the drying box 401 is provided with an arc-shaped baffle plate 407.

[0024] The outer wall of the drying box 401 is provided with a fan 408, and the outer wall of the drying box 401 is provided with an arc-shaped pipe 409, the arc-shaped pipe 409 is connected with the air outlet of the fan 408, the inner wall of the arc-shaped pipe 409 is provided with a heating wire 410, and the inner wall of the arc-shaped pipe 409 is provided with a plurality of air outlet pipes 411 at equal intervals, and the air outlet pipes 411 pass through the drying box 401 and are connected with the arc-shaped baffle 407;

[0025] The inner wall of the drying box 401 is rotatably provided with a material dividing plate 403, and a rotating shaft 412 is provided at one end of the drying box 401 close to the feeding end 2, and the material dividing plate 403 is arranged on the rotating shaft 412, and a torsion spring 413 is sleeved on the rotating shaft 412, one end of the torsion spring 413 is fixed to the material dividing plate 403, and the other end of the torsion spring 413 is fixed to the drying box 401, and a sealing rubber ring is provided on the outer wall of the material dividing plate 403;

[0026] When the material is poured into the feed end 2, the dividing plate 403 is tilted due to the influence of the gravity of the material, and the dividing plate 403 tilts and rotates, compressing the torsion spring 413, and the material gradually falls from the dividing plate into the drying box 401. When the material falls into the drying box 401 and contacts the drop plate 402, the heating plate 405 is turned on to heat the material, and the material gradually falls downward from the drop plate 402 evenly. When the material contacts the drop plate 402, the heat generated dries the material, and when the material drips from the drop plate 402 to the dividing plate, it passes through the dripping plate on the dividing plate. Hole 406 divides the material into smaller water droplets. When the small water droplets drip downward, the fan 408 is driven to rotate and the heating wire 410 is driven to turn on. The wind from the fan 408 blows toward the heating wire 410, and the hot air blows from the arc pipe 409 into the arc baffle 407 and contacts the dripping material, thereby drying the dripping material again. The hot air is blown out along the inner wall of the arc baffle 407, blowing the outermost droplets of material inward, so that the dripping material drips toward the middle side, further reducing the phenomenon of material hanging on the wall.

[0027] When the material at the feed end 2 flows into the drying box 401, the torsion spring 413 recovers its deformation and pushes the dividing plate 403 to return to its original position. After the dividing plate 403 returns to its original position, the sealing rubber ring contacts the inner wall of the drying box 401, thereby reducing the outflow of hot air in the drying box 401 and further improving the drying effect of the material.
