Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic hose production, and in particular relates to an environmentally friendly hose glue stripping and cleaning integrated device. Background Art

[0002] Hydraulic hose is an important pipe in various liquid and gas systems. During the hose processing, it is necessary to peel off a section of rubber at the end of the pipe to expose the steel wire or steel wire armor inside, and then press the stripped hose into the sleeve and core to complete the hose processing. Since foam will enter the hose port during the stripping process, it is necessary to clean the inside of the pipe after stripping. The cleaning process generally uses a brush to clean first, and then uses high-pressure air to blow the hose port. This operation method has the following disadvantages or shortcomings:

[0003] (1) The production efficiency is low due to the multiple processes of stripping glue first, brush cleaning, and high-pressure air blowing;

[0004] (2) During the process of high-pressure air blowing and cleaning the inner wall of the hose, the external stripping area is cleaned to the standard, but some of the glue foam will be blown deeper into the hose, making it difficult to pass the internal cleaning quality inspection of the hose, affecting product quality;

[0005] (3) Glue stripping and cleaning are both carried out in the workshop without any shielding or protective structures. This is not only highly dangerous, but the glue foam and dust generated also pollute the workshop environment. Utility Model Content

The operator holds the hose and passes the hose end through the hose jack on the right side of the box. The inner circle of the hose port moves to the left along the conical guide part at the rightmost end of the installation shaft, and is successively sleeved onto the installation shaft and the guide shaft. While the hose moves to the left, the stripping knife rotates at high speed with the connecting shaft to strip the rubber on the outer circle of the hose, and the stripped rubber falls into the lower rubber storage chamber at the bottom of the box; high-pressure air enters the inner hole of the hose through the jet hole. Since the jet hole outlet is located on the left side of the jet hole inlet, the high-pressure airflow is ejected to the left along the inner circle of the hose after being ejected through the jet hole. At the same time, the installation shaft drives the sleeve and several The nylon strip brush rotates at high speed to clean the inner wall of the hose. The dust brushed off is blown to the left through several guide grooves on the outer circle of the guide shaft to the outside of the left port of the hose under the action of high-pressure airflow, and the high-pressure airflow blows to the right end face of the connecting shaft. The high-pressure airflow blows to the right to clean the outer circle of the hose after stripping, until the left end of the hose contacts the right end of the connecting shaft, and the stripping length reaches the specified requirement. The hose is pulled to the right, and the outer circle of the hose is cleaned again by the high-speed rotating stripping knife. The hose is pulled out of the hose jack, and the foot switch is released to complete the integrated stripping and cleaning operation of the hose.

[0018] The functions of each component or structure in the utility model are as follows:

[0019] (1) The motor and the split-assembly type glue stripping and cleaning components are arranged in a box, and the split-assembly type glue stripping and cleaning components are separated by vertical partitions, so as to prevent the dust generated during the glue stripping process from polluting the motor and the electronic control components. At the same time, the peeled glue foam and rubber are also collected in the lower glue foam storage chamber at the bottom of the box to avoid polluting the workshop air environment. When a large amount of glue foam and rubber is stored, the unloading door is opened to clean the glue foam and rubber.

[0020] (2) When the motor, electronic control components and high-pressure air circuit components need to be maintained or overhauled, open the first inspection cover for operation. When the split assembly type stripping and cleaning components need to be maintained or overhauled, open the second inspection cover for operation. When the guide shaft, installation shaft or tool holder rod is wrapped with rubber, it can be operated through the cleaning ports at the top and bottom of the hose jack. If it is difficult to clean through the cleaning ports, open the second inspection cover for cleaning. The cleaning ports also function as observation holes, through which the stripping situation can be observed.

[0021] (3) Pneumatic slip ring (equivalent to a rotary joint, available on the market), the fixed cylindrical part is connected to the high-pressure air pipe, the rotating cylindrical part is coaxially threaded with the left end of the hollow main shaft, and the pneumatic slip ring is connected to the inside of the hollow main shaft through radial air passages and axial air passages.

[0022] (4) The split assembly type stripping and cleaning component uses a connecting shaft, a material guide shaft and a mounting shaft that are coaxially connected in sequence with threads, which is convenient for manufacturing, assembly and disassembly. The connecting shaft has the largest outer diameter, and the left port is used to connect with the outer circle thread of the right end of the hollow main shaft. The right port of the connecting shaft is connected with the outer circle thread of the left end of the material guide shaft. The right end face of the connecting shaft serves to limit the axial movement distance of the hose during the stripping process, and at the same time provides a reflection (refracting) annular plane for the high-pressure airflow.

[0023] (5) The conical part at the right end of the guide shaft plays the role of guiding air flow and dust. The dust along with the air flow is blown to the left along several guide grooves on the outer circle of the guide shaft. The outer diameter of the guide shaft and the outer diameter of the sealing section of the mounting shaft are equal and slightly smaller than the inner diameter of the hose. This can basically ensure the coaxiality of the hose when stripping the rubber.

[0024] (6) The external threaded section at the left end of the mounting shaft extends into and is threadedly connected to the inner circle of the right port of the guide shaft. The mounting section is used to install a sleeve with a nylon strip brush. The jet section is provided with three jet holes arranged in a circular array. The jet holes spray air to the left. The nylon strip brush rotates to clean the inner wall of the hose and blows the dust to the left out of the left port of the hose through a high-pressure airflow. This also prevents the glue foam during the stripping process from entering the inside of the hose.

[0025] To sum up, the utility model has a scientific principle, and the rubber stripping operation is carried out as a whole inside the box, which not only improves safety, but also prevents dust from spreading outward, and at the same time collects the peeled rubber and rubber foam; the utility model integrates the rubber stripping of the outer circle of the hose and the cleaning of the inner circle of the pipe mouth, and while the inner circle of the pipe mouth is cleaned with high-pressure airflow and a brush, the blown-out high-pressure gas also blows up and cleans the circumferential surface after the rubber stripping, which greatly improves work efficiency and prevents impurities from entering the pipe mouth after rubber stripping.
