Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber hoses, in particular to a rubber extruder for producing rubber hoses. Background Art
[0002] The rubber hose is a steel wire braided hose. The hose consists of an inner rubber layer, a steel wire braided layer and an outer rubber layer. It is suitable for conveying hydraulic fluids such as alcohol, fuel, lubricating oil, emulsion, etc. During the production process of the rubber hose, the rubber material needs to be put into the extruder and extruded through the outlet. However, the outlet of the existing extruder can only meet the extrusion of rubber hoses of one size, and it is impossible to flexibly replace rubber hoses of multiple sizes, resulting in insufficient adaptability of the equipment. Based on the existing technical deficiencies, the utility model designs a rubber extruder for rubber hose production. Utility Model Content

[0005] As a preferred technical solution of the utility model, a support ring is installed on the top of the base, and the support ring is sleeved with the forming cylinder.
[0006] As a preferred technical solution of the utility model, a cutting structure is installed on one side of the top of the base, and the cutting structure includes two mounting seats.
[0007] As a preferred technical solution of the utility model, a limiting slot plate is installed on the top of the two mounting seats, a fixing ring is installed on the top of one of the limiting slot plates, and a limiting rod is installed inside the other limiting slot plate.
[0008] As a preferred technical solution of the utility model, a servo motor is installed inside the fixing ring, and a screw rod is installed at one end of the output shaft of the servo motor.
[0009] As a preferred technical solution of the utility model, a threaded block is threadedly installed on the outer surface of the screw rod, and another threaded block is sleeved on the outer surface of the limiting rod.
[0010] As a preferred technical solution of the utility model, a steel wire is installed between the two threaded blocks.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. A rubber extruder for producing a rubber hose can flexibly adjust the size of the extruded rubber hose by replacing the two extrusion heads when the rubber hose is formed by replacing the structure. When replacing, the threaded rod is rotated out of the extension plate by turning the first turning handle, and the rotating round rod is loosened at this time. The rotating round rod is driven to move part of the rotating cross bar out of the extension plate by pulling the second turning handle, and the slot column is separated from the extrusion slot at this time. At this time, the rotating cross bar drives the left slot column and the right slot column to exchange positions by turning the second turning handle. At this time, the rotating round rod is inserted into the extension plate again so that the slot column is stuck in the extrusion slot. At this time, the threaded rod is moved in the extension plate by turning the first turning handle again to hold the rotating round rod against the rotation. The two extrusion heads are swapped, thereby improving the adaptability of the device.
[0013] 2. A rubber extruder for producing a rubber hose has a cutting structure. After the rubber hose is formed, it is generally cut manually with scissors. Since the hose is soft, the blade collapses when the scissors cut it short, affecting subsequent use. Therefore, when it comes out of the extruder, the servo motor is started so that its output shaft drives the screw to rotate, thereby allowing the threaded block on one side to drive the threaded block on the other side to move horizontally on the outer surface of the screw and the limit rod, so that the steel wire can cut the rubber hose into uniform segments. At the same time, the problem of defective blades caused by manual cutting in the prior art can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 2 and Figure 5A support ring 7 is installed on the top of the base 1, and the support ring 7 is sleeved with the forming tube 4. A cutting structure 6 is installed on one side of the top of the base 1, and the cutting structure 6 includes two mounting seats 61. A limiting slot plate 62 is installed on the top of the two mounting seats 61, and a fixing ring 63 is installed on the top of one of the limiting slot plates 62, and a limiting rod 67 is installed inside the other limiting slot plate 62. A servo motor 64 is installed inside the fixing ring 63, and a screw rod 65 is installed at one end of the output shaft of the servo motor 64. A threaded block 66 is threadedly installed on the outer surface of the screw rod 65, and another threaded block 66 is sleeved on the outer surface of the limiting rod 67. A steel wire 68 is installed between the two threaded blocks 66.
[0023] The forming cylinder 4 is supported by the support ring 7. By starting the servo motor 64, its output shaft drives the screw 65 to rotate, so that the threaded block 66 on one side drives the threaded block 66 on the other side to move horizontally on the outer surface of the screw 65 and the limit rod 67, so that the steel wire 68 can cut the rubber hose into uniform segments, and at the same time, the problem of defective blades caused by manual cutting in the prior art can be avoided.
[0024] Working principle: when a rubber extruder for producing a rubber hose is used, in the initial state, first, the rubber raw material is fed from the feed port 3, and the extruder body 2 is started to work. After the rubber raw material is formed by the forming cylinder 4, it is extruded and formed by the extrusion head 510. If the size of the rubber hose needs to be adjusted, the first turning handle 57 is turned to make the threaded rod 56 rotate out of the extension plate 53. At this time, the rotating round rod 55 is loosened, and the rotating round rod 55 is pulled by pulling the second turning handle 58 to drive the rotating cross rod 52 to move part of the extension plate 53. At this time, the slot column 59 is separated from the extrusion slot 8. At this time, the second turning handle 58 is turned to make the rotating cross rod 52 drive The left slot column 59 is swapped with the right slot column 59. At this time, the rotating round rod 55 is inserted into the extension plate 53 again so that the slot column 59 is stuck in the extrusion slot 8. At this time, the threaded rod 56 is moved in the extension plate 53 by rotating the first turning handle 57 to support and fix the rotating round rod 55, thereby completing the swap of the two extrusion heads 510. After the rubber hose is formed, in order to avoid the collapse of the blade during cutting, the servo motor 64 is started so that its output shaft drives the screw 65 to rotate, thereby allowing the threaded block 66 on one side to drive the threaded block 66 on the other side to move horizontally on the outer surface of the screw 65 and the limit rod 67, so that the steel wire 68 can cut the rubber hose into uniform segments.
