Description

Technical Field

[0002] A hose, also known as a hose or rubber hose, is a flexible conduit primarily used to transport fluids (liquids, gases), powdered materials, or power. Its core value lies in its three functions: connection, protection, and cushioning. Its specific applications include industrial, medical, and civilian applications. Its production utilizes extrusion molding equipment, with a multi-step process involving plasticizing the rubber compound, die forming, vacuum setting, and water-cooled cutting. This allows for rapid and efficient production, ensuring sufficient output to meet actual usage requirements.

[0003] Nowadays, in the final cutting process of hose production and molding, the conveying device continuously transports the continuously formed hose forward. Although the fixed tool can quickly cut and cut off each fixed length of hose, since the hose is continuously transported forward, there is an extrusion force between the tool and the pushed hose cross-section during the cutting state, resulting in the cut being actually tilted and uneven, and requiring subsequent polishing and finishing processing. Therefore, the production cycle is extended, production efficiency is reduced, and the production cost is increased.

[0004] Therefore, in view of the above-mentioned problem that in the final cutting process of the existing hose production and molding, there is an extrusion force between the fixed tool and the pushed hose cross-section in the cutting state, which causes the incision to be tilted and uneven, and further polishing and finishing are required, which prolongs the production cycle, reduces production efficiency, and increases the production cost. An extrusion molding equipment can be designed that can improve the smoothness of the hose incision during the cutting process. Utility Model Content

The conveyor body 4 will continuously convey the cooled and molded hose. The direction of the conveyor body 4 conveying the hose is aligned with the discharge pipe 6, so the hose passes through the discharge pipe 6 in the fixed box 5 and is continuously conveyed to the left. The hose conveying rate is controlled by the PLC control system, and the displacement mechanism is used to control the N-shaped frame 10 to move to the left at a synchronous rate.

The cut hose falls to complete the blanking, and then the displacement mechanism adjusts the N-shaped frame 10 to return to its original position to carry out the next hose cutting and cutting task.

[0032] Through the above steps, the present device is modified by the cutting device process in the hose extrusion molding equipment, and an N-shaped frame 10 is added under the control of the displacement mechanism, and a cutting knife 12 controlled by the lifting mechanism is arranged at the bottom of the N-shaped frame 10, and two sets of arc-shaped clips 14 controlled by the pushing mechanism are controlled to control the N-shaped frame 10 and the output hose to move in the same direction and at the same rate, and the two sets of arc-shaped clips 14 are used to clamp and fix the output hose at two positions, and then the cutting knife 12 is used to fall and cut. At this time, the cutting knife 12 and the output hose are in a relatively static state in the left and right directions, and the cutting is completed. The vertical movement of the cutting knife 12 is not affected by the left and right conveying of the hose, so the resulting incision is relatively flat and smooth, and is not prone to tilting. This reduces the subsequent further processing work, shortens the production cycle, improves production efficiency, and saves production costs. This solves the problem that in the final cutting process of the existing hose production and molding, there is an extrusion force between the fixed tool and the pushed hose cross section in the cutting state, resulting in an uneven incision, which requires further polishing and finishing, extending the production cycle, reducing production efficiency, and increasing the production cost.
