Crushing device for rubber pipe preparation and processing

Abstract

According to the smashing device for rubber pipe preparation and processing, the smashing blades are driven by the driving shaft to rotate in the processing cavity, materials contained in the processing cavity are smashed, and the smashed materials are discharged outwards from the discharging opening of the discharging cavity after being screened by the screen. The material scraping plate and the material blocking plate are arranged on the two sides of the screen correspondingly, in the rotating process of the smashing blade, the smashing blade firstly passes through the material scraping plate and then passes through the material blocking plate, and when the outer edge of the smashing blade passes through the material scraping plate, more materials accumulated on the smashing blade can be scraped under the blocking effect of the material scraping plate; when the crushing blades rotate to be far away from the screen, excessive materials mingled on the crushing blades can be scraped back into the screen under the action of a material baffle plate, so that the crushing efficiency is improved, and the crushing efficiency is improved. Therefore, the crushing treatment device for preparing and processing the rubber tube can effectively improve the crushing and cutting efficiency of the crushing treatment device.

Description

Technical Field

[0001] The utility model relates to the technical field of hose processing equipment, in particular to a crushing device used for hose preparation and processing. Background Art

[0002] During the preparation and processing of hoses, some links may require pulverization in order to properly treat and reuse the raw materials or waste generated. The links that require pulverization during the processing of hoses include: (1) Raw material preparation: If the raw materials used are large or large-sized rubber blocks, plastic blocks, etc., these raw materials may need to be pulverized before preparation and processing. This helps to improve the processability of the raw materials and ensure that they are easier to mix and extrude in subsequent steps; (2) Recycled material processing: In the preparation of hoses, recycled rubber or recycled plastic may be used. These recycled materials usually need to be pulverized to ensure that their particle size is uniform, which is conducive to mixing and fully mixing with new materials; (3) Waste treatment: In the production of hoses, waste, trimming edges, unqualified products, etc. may be generated. These wastes usually need to be pulverized for recycling or more convenient waste treatment. Existing pulverization devices usually use shear pulverization, which mainly achieves the purpose of pulverization by deforming and breaking the material under the shearing action of the blade or tool, or extrusion crushing: by placing the material between two relatively moving extrusion surfaces, the material is extruded, sheared and crushed. However, in the existing crushing device, during operation, as the shredding tool rotates, some materials will be thrown to other locations, affecting the output. In addition, when the shredding tool rotates for a long time, some materials will accumulate on the shredding tool, thereby affecting the subsequent crushing efficiency. Utility Model Content

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] See also Figure 1 As shown in FIG. 4 , the utility model provides a crushing device for preparing and processing a rubber hose, which includes a frame 11, a processing chamber 12, a discharge chamber 13, a drive shaft 21, a crushing blade 22, a screen 31, a scraper plate 32, and a baffle plate 33.

[0020] The processing chamber 12 is fixedly arranged on the frame 11, and a feeding port 121 is arranged at the top of the processing chamber 12. A discharge chamber 13 is arranged at the bottom of the processing chamber 12, and the discharge chamber 13 is connected to the processing chamber 12. A discharge port 131 is arranged at the end of the discharge chamber 13. The crushing blade 22 is driven to rotate in the processing chamber 12 by the rotation of the driving shaft 21, so that the material contained in the processing chamber 12 is crushed, and the crushed material is discharged from the discharge port 131 of the discharge chamber 13 after being screened by the screen 31.

[0021] Both ends of the driving shaft 21 are rotatably connected to the inner wall of the processing chamber 12, and multiple crushing blades 22 are fixedly arranged on the driving shaft 21. The multiple crushing blades 22 are arranged at intervals along the axial direction of the driving shaft 21, and the multiple crushing blades 22 are staggered along the circular axis direction of the driving shaft 21. The driving shaft 21 is used to connect to a driving component, and the driving component is a motor. The driving component drives the driving shaft 21 to rotate, and the rotation of the driving shaft 21 drives the crushing blades 22 to rotate in the processing chamber 12.

[0022] The screen 31 is fixedly disposed inside the processing chamber 12 and located above the discharge chamber 13 . The cross section of the screen 31 along the vertical direction is semicircular, and a plurality of screen holes are disposed on the screen 31 .
