Abstract
Description
Technical Field
[0001] This invention relates to the field of hose assembly processing technology, specifically to a hose cleaning and rinsing device after hose unloading. Background Technology
[0002] During the processing of rubber hose assemblies, after the hoses are cut, their inner cavities are prone to retaining rubber debris from the cutting process, dust adhering to the material, and impurities from the production environment. If not effectively cleaned, these impurities can enter the hydraulic or pneumatic systems during subsequent assembly or use, leading to system blockages, component wear, or performance degradation, severely impacting product quality and lifespan. Current methods for cleaning the inner cavities of rubber hoses mostly involve manual rinsing or unidirectional high-pressure water jet rinsing. Manual rinsing is inefficient, labor-intensive, and produces uneven cleaning results, making it difficult to thoroughly remove contaminants from dead corners. Unidirectional high-pressure rinsing has blind spots, allowing contaminants to accumulate in these areas, failing to achieve comprehensive cleaning. Therefore, there is an urgent need for a high-efficiency, thorough cleaning device for the inner cavities of rubber hoses. Summary of the Invention
[0003] The purpose of this invention is to provide a device for cleaning and rinsing the inner cavity of a rubber hose after it has been unloaded, so as to solve the problems of low cleaning efficiency and unsatisfactory cleaning effect in the existing rubber hose inner cavity cleaning methods mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: A device for cleaning and rinsing the inner cavity of a rubber hose after feeding includes a cleaning machine and a frame. The cleaning machine is provided with a water inlet and a water outlet. A three-way connector is fixedly connected to the water outlet. Both ends of the three-way connector are respectively connected to a rinsing unit through a hose. A ball valve is provided between the hose and the rinsing unit. The rinsing unit is fixedly connected to the frame. The rinsing unit is provided with a rinsing pipe component. Both ends of the rinsing pipe component are provided with a plurality of spray nozzles that are at a certain angle to the axis of the rinsing pipe component and are opposite to each other. The middle section of the rinsing pipe component is provided with a plurality of rows of spray nozzles perpendicular to the axis of the rinsing pipe component.
[0005] Furthermore, the rinsing unit includes a rinsing cylinder and a rinsing pipe assembly. A left end cap and a right end cap are fixedly connected to both ends of the rinsing cylinder, respectively. A protective sleeve is fixedly installed between the left end cap and the rinsing cylinder. The protective sleeve is fixedly connected to the frame by a fixing clamp. A straight connector is fixedly installed at the center of the left end cap. One end of the straight connector is fixedly connected to a ball valve, and the other end is fixedly connected to the rinsing pipe assembly.
[0006] Furthermore, the flushing pipe component includes a flushing pipe, a guide head, and a guide plate. The guide head is fixedly connected to the guide plate. The left end of the flushing pipe is screwed to a straight connector. The right end of the flushing pipe passes through the guide plate, extends into the guide head, and is fixedly connected to the guide plate. The left end of the flushing pipe has several first spray ports, which are evenly distributed around the body of the flushing pipe and spray towards the right end of the flushing pipe. The flushing pipe has several rows of second spray ports along its body, and the spray direction of the second spray ports is perpendicular to the axis of the flushing pipe. The guide plate has several third spray ports evenly distributed around its body, and the spray direction of the third spray ports is towards the left end of the flushing pipe. The closed area between the flushing pipe, the guide head, and the guide plate forms a water flow channel.
[0007] Furthermore, the spray angle α of the first spray nozzle is 15 to 30 degrees, and the spray angle β of the second spray nozzle is 15 to 30 degrees.
[0008] Furthermore, the first, second, and third injection ports are circumferentially offset from each other.

[0010] Furthermore, an outlet is provided at the lower part of the left end cap, and the outlet is connected to a pipe that connects to the wastewater pipe network.
[0011] Furthermore, a rubber tube inlet is provided at the center of the right end cap.
[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes multiple sets of spray nozzles with different directions and angles to create multi-directional cross-flow water, achieving bidirectional counter-current flushing and radial full-coverage rinsing of the hose's inner cavity. This enhances the rinsing coverage of the hose's inner wall, eliminates blind spots, and simultaneously utilizes the impact force of the reverse water flow to enhance contaminant removal. Furthermore, the spray nozzles are circumferentially staggered to avoid water flow interference, ensuring thorough removal of rubber debris, dust, and other contaminants.

Detailed Implementation
[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0015] Please see Figures 1-4 One embodiment provided by the present invention: A device for cleaning and rinsing the inner cavity of a rubber hose after unloading includes a cleaning machine 1 and a frame (not shown in the attached drawings). The cleaning machine 1 is provided with a water inlet 2 and a water outlet 3. A three-way connector 4 is fixedly connected to the water outlet 3. Both ends of the three-way connector 4 are connected to a rinsing unit 8 through a hose 5, which can clean two rubber hoses at the same time, greatly improving work efficiency. A ball valve 6 is provided between the hose 5 and the rinsing unit 8 for opening or closing the water inlet of the rinsing unit 8. The rinsing unit 8 is fixedly connected to the frame. The rinsing unit 8 is provided with a rinsing pipe component. Several spray nozzles are provided at both ends of the rinsing pipe component at a certain angle and in opposite directions to each other. Several rows of spray nozzles perpendicular to the axis of the rinsing pipe component are provided in the middle section of the rinsing pipe component. The purpose is to form a multi-directional cross water flow to achieve bidirectional flushing and radial full-coverage rinsing of the inner cavity of the rubber hose, enhance the flushing coverage of the inner wall of the rubber hose, eliminate rinsing blind spots, and at the same time enhance the pollutant removal effect by utilizing the impact force of the reverse water flow.
[0016] The rinsing unit 8 includes a rinsing cylinder 804 and a rinsing pipe assembly. The rinsing cylinder 804 is fixedly connected to a left end cover 801 and a right end cover 805 at its two ends, respectively. A protective sleeve 803 is fixedly installed between the left end cover 801 and the rinsing cylinder 804. The protective sleeve 803 is fixedly connected to the frame through a fixing clamp 7. A straight connector 802 is fixedly installed at the center of the left end cover 801. One end of the straight connector 802 is fixedly connected to a ball valve 6, and the other end is fixedly connected to the rinsing pipe assembly.
[0017] The flushing pipe assembly includes a flushing pipe 806, a guide head 807, and a guide plate 808. The guide head 807 is fixedly connected to the guide plate 808. The left end of the flushing pipe 806 is screwed to a straight connector 802. The right end of the flushing pipe 806 passes through the guide plate 808, extends into the guide head 807, and is fixedly connected to the guide plate 808. The left end of the flushing pipe 806 has six first spray ports 806A, which are evenly distributed circumferentially on the body of the flushing pipe 806, and the spray direction is towards... At the right end of the flushing pipe 806, several rows of second jet nozzles 806B are arranged along the pipe body, with 6 nozzles in each row and evenly distributed around the circumference. The jet direction of the second jet nozzles 806B is perpendicular to the axis of the flushing pipe 806. Several third jet nozzles 808A are evenly distributed on the guide plate 808. The jet direction of the third jet nozzles 808A is towards the left end of the flushing pipe 806. A closed water flow channel 807C is formed between the flushing pipe 806, the guide head 807, and the guide plate 808.
[0018] The spray angle α of the first spray nozzle 806A is 15 to 30 degrees, and the spray angle β of the third spray nozzle 808A is 15 to 30 degrees. This angle range can expand the coverage area and improve the cleaning efficiency while ensuring the water flow impact force. The spray angle refers to the angle between the axis of the spray nozzle and the axis of the flushing pipe 806.
[0019] The first injection port 806A, the second injection port 806B, and the third injection port 808A are circumferentially staggered, as... Figure 4 As shown, this avoids interference between the sprayed water streams, ensuring that the water stream from each nozzle can independently cover the corresponding cleaning area, achieving full coverage rinsing of the hose cavity without dead angles, and improving the uniformity of water flow distribution and cleaning effect.
[0020] The flushing pipe 806 extends into the guide head 807 and is provided with a first rounded edge 806C. The center of the inner bottom of the guide head 807 is provided with a hemispherical surface 807A, which is used to reflect the direction of water flow, guide the water flow to spread evenly, reduce eddies, and enable the high-pressure water flowing out from the right end of the flushing pipe 806 to be evenly dispersed along the hemispherical surface 807A to the water flow channel 807C, avoiding the impact force loss caused by direct water flow and improving the water flow guidance. The periphery of the inner bottom of the guide head 807 is provided with a second rounded edge 807B. The first rounded edge 806C and the second rounded edge 807B work together to reduce the resistance of water flow at corners, reduce water flow energy loss, prevent turbulence, and improve water flow smoothness and flushing pressure.
[0021] The lower part of the left end cover 801 has an outlet 801A, which is connected to a pipe and connected to the wastewater pipe network.
[0022] The right end cover 805 has a hose inlet 805A in the center, which is used to send the hose to be rinsed into the rinsing cylinder 804 so that the hose can be put into the rinsing pipe component for cleaning. The right end cover 805 is also used to block the water flow sprayed from the first spray port 806A to prevent splashing of surrounding equipment and personnel.
[0023] Working principle of this invention: When cleaning the inner cavity of the hose after unloading, the cleaning machine 1 is started and the ball valve 6 is opened. High-pressure water enters the flushing pipe 806 from the outlet 3 through the three-way connector 4, the hose 5, and the ball valve 6. It is sprayed out from the first spray port 806A and the second spray port 806B. The high-pressure water continues to flow to the right end of the flushing pipe 806. Under the reflection and guiding effect of the hemispherical surface 807A, it is sprayed out from the third spray port 808A through the water flow channel 807C. The hose is inserted into the flushing pipe component from the hose inlet 805A. The multi-directional high-pressure water sprayed from the first spray port 806A, the second spray port 806B, and the third spray port 808A works together on the inner wall of the hose to achieve efficient and thorough cleaning. The cleaned water flows into the wastewater network through the outlet 801A, realizing the centralized discharge of the contaminated wastewater.
