Description

Technical Field

[0001] This utility model belongs to the field of hose processing technology, and in particular to a hose production extrusion device. Background Technology

[0002] Hydraulic hoses require an extrusion unit during production. This unit utilizes the pressure and shearing force generated by a rotating screw to fully plasticize and uniformly mix the material. The material is then formed through a die. During extrusion, plastic granules are typically fed into the extrusion unit through a feeding funnel and then extruded by the screw. The size and temperature of the plastic granules affect the extrusion effect, and the process also produces odorous gases. Existing equipment uses treatment components to manage these odors and protect workers' health. While this provides some protection, the open-type feed pipe requires manual installation of a sealing cap to prevent odor escape, increasing the workload for workers.

[0003] A search revealed Chinese patent document (authorization announcement number CN214562773U). This utility model relates to the technical field of equipment for hydraulic hose production, and particularly to an extrusion device for hydraulic hose production. The device includes a support platform and a screw. From left to right, an extrusion motor, a reducer, a barrel, and a die head are sequentially arranged on the support platform. One end of the reducer is rotatably connected to the extrusion motor, and the other end is rotatably connected to the screw. The screw is located inside the barrel, and the die head is located at the right end of the barrel. The device also includes a feeding device and a waste gas collection and treatment device. While this patent ensures the physical and mental health of workers to some extent, the device's inlet pipe is an open design, requiring manual assistance to install a sealing cap to prevent odor gases from escaping, thus increasing the workload of workers.

[0011] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0012] This hose production extrusion device, thanks to the design of the auxiliary plates and processing components, allows the raw materials to be added into the feed hopper. After being squeezed by the raw materials, the two auxiliary plates press against the movable block at one end of the movable rod. When the movable block is under certain pressure, it squeezes the return spring, causing the two auxiliary plates to open, thus achieving the feeding effect. After feeding is completed under the elastic force of the return spring, the two auxiliary plates will return to their original positions. Compared with the feeding method of existing devices, this device can automatically close the feed port, effectively preventing odorous gases from escaping and greatly reducing the workload of workers. Furthermore, the design of the processing components can treat odorous gases, thereby ensuring the physical and mental health of workers.

[0013] This hose production extrusion device can automatically close the feed inlet, effectively preventing odorous gases from escaping and greatly reducing the workload of workers. Attached Figure Description

A heating component 8 for melting the raw material is installed on the side of the material cylinder 7. The top of the material cylinder 7 is connected to a feed hopper 10. The feed hopper 10 has a shape that is larger at the top and smaller at the bottom, which facilitates the operation of feeding the material.

A rubber strip is installed at one end of each of the two auxiliary plates 11 to reduce the outflow of gas. A movable rod 13 is hinged to the side of the movable block 14, and the end of the movable rod 13 away from the movable block 14 is hinged to the auxiliary plate 11.

[0025] A mounting frame 5 is fixedly connected to the side of the mounting platform 1, and an extrusion motor 6 that provides power to the components inside the extrusion cylinder 2 is mounted on the side of the mounting frame 5.

The scale of the attached drawings is for reference only and can be adjusted to a certain extent according to the actual use.

[0028] Working principle

[0029] In use, the extrusion device for producing rubber hoses works by adding the required raw material into the feed hopper 10. After being squeezed by the raw material, the two auxiliary plates 11 will squeeze the movable block 14 at one end of the movable rod 13. After the movable block 14 is subjected to a certain pressure, it will squeeze the return spring 16, causing the two auxiliary plates 11 to open, thereby achieving the feeding effect. The raw material after feeding enters the feed cylinder 7. The heating component 8 and the drive motor 9 are started. The start of the drive motor 9 drives the crushing rod 17 to rotate and crush the raw material. After the raw material is processed, the control valve is opened, allowing the raw material to enter the extrusion cylinder 2 for rubber hose processing. During the raw material heating process, the exhaust fan 41 is started to draw the odor gas into the treatment box 45 for adsorption treatment.
