Description

Technical Field

[0001] The utility model relates to the technical field of molding machines, and more particularly to a rubber hose extrusion molding machine. Background Art

[0002] A rubber hose is a hollow flexible tubular rubber product, and its structure mainly consists of an inner rubber layer, a skeleton layer (such as a steel wire braided layer or a fiber textile), and an outer rubber layer. Those without a skeleton layer are pure rubber hoses. Due to its excellent flexibility, durability, and sealing performance, rubber hoses are widely used in the medium and power transmission systems in various industries, such as the fields of petroleum, chemical industry, shipbuilding, agriculture, food, beverage, and medicine. It can transport or pump media such as water, oil, gas, chemicals, or particulate materials under positive or negative pressure conditions.

[0003] A rubber hose extrusion molding machine is a mechanical device for producing various rubber hoses. It forms a continuous hose with a required cross-sectional shape by feeding the heated rubber material into the extrusion barrel and extruding it through a die with a specific shape. This process can adjust the material formula and extrusion parameters according to needs to meet the requirements of hose performance in different application fields.

[0004] Deficiencies of the existing rubber hose extrusion molding machines:

[0005] Firstly: The raw materials in the rubber hose extrusion molding machine are a mixture mainly composed of raw rubber placed in a storage bucket for use by the molding machine and are transmitted to the feed pipe in the molding machine through a copper pipe. However, the raw materials will solidify and stratify in the storage bucket, thereby affecting the quality of the extruded hose.

[0006] Secondly: After the rubber hose extrusion molding machine finishes working, a small amount of rubber will solidify on the extrusion port, and the rubber solidified on the extrusion port may be mixed into the new rubber hose during the next startup, resulting in defects on the surface of the hose. Content of the Utility Model

[0007] In order to overcome the above-mentioned defects of the prior art, the utility model provides a rubber hose extrusion molding machine to solve the problems existing in the above-mentioned background art.

[0008] The utility model provides the following technical solution: A rubber hose extrusion molding machine includes a protection box. A storage bucket is fixedly connected to the top of the protection box. A first transmission rod is provided on the inner surface of the storage bucket. A scraper is movably connected to the inner surface of the storage bucket. Scraping surfaces are provided on both sides of the scraper. An extrusion port is fixedly connected to one side of the protection box. A cleaning block is provided on the top of the extrusion port. A second transmission rod is fixedly connected to the inner surface of the cleaning block. A connecting rod is fixedly connected to the front of the second transmission rod. A cleaning block is fixedly connected to the front of the connecting rod;

[0009] Furthermore, a first motor is fixedly connected to the top of the storage barrel. A first conical gear is fixedly connected to one side of the first motor. A second conical gear is movably connected to the outer surface of the first conical gear. A first transmission rod is fixedly connected to the bottom of the second conical gear. Stirring plates are fixedly connected to the outer surface of the first transmission rod. A connecting plate is fixedly connected to the middle of the first transmission rod. A scraping plate is fixedly connected to one side of the connecting plate.

[0010] Furthermore, an extruder is provided on the inner surface of the protection box. A transmission copper pipe is fixedly connected to one side of the extruder. A storage barrel is fixedly connected to the top of the transmission copper pipe. An extrusion port is fixedly connected to the other side of the extruder. A limiting groove is opened at the top of the extrusion port.

[0011] Furthermore, a limiting block is movably connected to the inner surface of the limiting groove. A first folding block is fixedly connected to the top of the limiting block. A hinge is fixedly connected to the top of the first folding block. A second folding block is fixedly connected to the top of the hinge. A second motor is fixedly connected to the top of the second folding block.

[0012] Furthermore, a second motor is fixedly connected to one side of the second transmission rod. A second folding block is fixedly connected to the bottom of the second motor. A cleaning groove is opened on the inner surface of the cleaning block. The extrusion port is movably connected to the inner surface of the cleaning groove.

[0013] Furthermore, through holes are opened on the inner surfaces of the stirring plates and the connecting plate.

[0014] Technical effects and advantages of the present utility model:

[0015] When the present utility model is in use, to ensure that the raw materials in the storage barrel are fully mixed, the first motor is started to make the first conical gear start to rotate. When the first conical gear starts to rotate, the second conical gear starts to rotate. At this time, the first transmission rod connected to the second conical gear starts to rotate. When the first transmission rod rotates, the stirring plates and the connecting plate start to stir in the storage barrel to fully mix the raw materials. Through the setting of the through holes, the raw materials can be effectively dispersed. Through the design of the stirring plates and the connecting plate, combined with the setting of the through holes, the raw materials in the storage barrel can be effectively stirred, which not only helps the uniform distribution of the raw materials, but also can reduce the adhesion of the raw materials to the inner wall of the storage barrel through the scraping plate, ensuring that all the raw materials in the entire storage barrel can be fully mixed.

[0016] When the extrusion outlet of the present utility model needs to be cleaned, the first folding block is pushed to one end of the extrusion outlet. Subsequently, due to the arrangement of the hinge, the second folding block is folded downward so that the cleaning block enters the interior of the extrusion outlet. Then, the second motor is started to make the second transmission rod start to rotate. When the second transmission rod rotates, the cleaning block quickly drives to remove the glue adhered inside the extrusion outlet. At this time, the connecting rod drives the cleaning block to rotate, and the inner surface of the cleaning block contacts the front end of the extrusion outlet. Along with the start of the second motor, the edge of the extrusion outlet is cleaned. By promptly cleaning the solidified rubber, the possibility of defects in the rubber hose can be significantly reduced, and the overall quality of the product can be improved.
