Description

Technical Field

[0001] This utility model relates to the field of hose manufacturing technology, specifically to a hose extrusion device. Background Technology

[0002] Rubber hoses are tubular rubber products used to transport gases, liquids, and other materials. They consist of an inner rubber layer, an outer rubber layer, and a reinforcing layer. Common materials include PVC and natural rubber. They come in various types, such as fabric-reinforced and braided hoses. They have good elasticity and corrosion resistance and are widely used in water, gas, and food transportation.

[0003] During the production process of rubber hoses, the hoses need to be extruded and formed by an extruder. When the existing extruder needs to cut the hoses after extrusion, it usually does so by cutting the hoses vertically with a cutting blade. Vertical cutting can easily deform the relatively soft hoses that have just been extruded, making the ends of the hoses unusable and thus causing waste. Utility Model Content

[0016] like Figures 1-4 As shown, this embodiment proposes a hose extrusion device, including an extrusion cylinder 1, with a feed box 2 connected to the top of the extrusion cylinder 1.

The support rod 4 is fixedly connected inside the rotating tube 3, and one end of the support rod 4 extends outside the extrusion end of the extrusion cylinder 1. The extrusion paddle 5 is fixedly connected... On the rotating tube 3, the rubber material can be extruded downwards under the drive of the rotating tube 3. The rotating ring 6 is set at the extrusion end of the extrusion cylinder 1 through the surrounding mechanism. The surrounding mechanism is used to drive the rotating ring 6 to rotate at the end of the extrusion cylinder 1. The cutting blade 7 is set on the rotating ring 6 through the lifting mechanism. The lifting mechanism is used to drive the cutting blade 7 to cut into the rubber tube. Through the arrangement of the rotating tube 3, support rod 4, extrusion paddle 5, rotating ring 6, cutting blade 7, rotating mechanism, surrounding mechanism and lifting mechanism, the rubber tube can be cut around it, which effectively prevents the deformation of the cutting position of the rubber tube and reduces the damage and waste at the end of the rubber tube.

[0017] The rotating mechanism includes a fixed frame 8, a rotating gear 9, a drive gear 10, and a first motor 11. The fixed frame 8 is fixedly connected to one end of the extrusion cylinder 1. One end of the support rod 4 passes through the extrusion cylinder 1 and is fixedly connected to the inner wall of the fixed frame 8. The rotating gear 9 is fixedly connected to one end of the rotating tube 3. The drive gear 10 is located inside the fixed frame 8 and meshes with the rotating gear 9. The first motor 11 is installed on one side of the fixed frame 8. The output end of the first motor 11 passes through the fixed frame 8 and is fixedly connected to the drive gear 10. The first motor 11 drives the drive gear 10 to rotate. When the drive gear 10 rotates, it drives the rotating gear 9 and the rotating tube 3 to rotate. When the rotating tube 3 rotates, it drives the extrusion paddle 5 to rotate, extruding the rubber material in the extrusion cylinder 1.

[0018] The circumferential mechanism includes a gear ring 12, a drive gear 13, and a second motor 14. The gear ring 12 is fixedly connected to the rotating ring 6. The drive gear 13 is located at the bottom end of the gear ring 12 and meshes with the gear ring 12. The second motor 14 is mounted on the extrusion cylinder 1. The output end of the second motor 14 is fixedly connected to the drive gear 13. The second motor 14 drives the drive gear 13 to rotate. When the drive gear 13 rotates, it drives the gear ring 12 and the rotating ring 6 to rotate.

[0019] The lifting mechanism includes a support frame 15, a slide 16, and a first electric cylinder 17. The support frame 15 is fixedly connected to the top of the rotating ring 6. The slide 16 is slidably connected to one side of the support frame 15 via a sliding assembly. The cutting blade 7 is rotatably connected to one side of the slide 16.

The slide 16 is driven to descend by the first electric cylinder 17. When the slide 16 descends, the slide rod 18 slides in the sliding hole on the stabilizing plate 19, thereby increasing the stability of the slide 16 when it slides. When the slide 16 descends and slides, it drives the cutting blade 7 to cut into the rubber tube.

[0020] The working principle is as follows: When the rubber material needs to be extruded, the first motor 11 drives the drive gear 10 to rotate. When the drive gear 10 rotates, it drives the rotating gear 9 and the rotating tube 3 to rotate. When the rotating tube 3 rotates, it drives the extrusion paddle 5 to rotate, extruding the rubber material in the extrusion cylinder 1. When the rubber sheet needs to be cut, the first electric cylinder 17 drives the slide 16 to descend. When the slide 16 descends, the slide rod 18 slides in the sliding hole opened on the stabilizing plate 19, thereby increasing the stability of the slide 16 during sliding. When the slide 16 descends and slides, it drives the cutting blade 7 to cut into the rubber tube. Then, the second motor 14 drives the power gear 13 to rotate. When the power gear 13 rotates, it drives the gear ring 12 and the rotating ring 6 to rotate, thereby driving the cutting blade 7 to rotate around the support rod 4, thereby cutting the rubber tube sleeved on the support rod 4 around it, thus effectively preventing the deformation of the rubber tube and reducing waste at the end of the rubber tube.
