Description

Technical Field

[0001] The invention relates to a cloth-wrapped rubber hose production device, and more specifically, to a cloth-wrapped rubber hose cloth-wrapping device. Background Art

[0002] Traditional cloth-wrapped hoses are labor-intensive industries due to their complex product structure, cumbersome processes, excessive reliance on labor production, and high labor intensity; pure manual production leads to inconsistent product quality and low production efficiency. The invention patent with publication number CN101328994 discloses a cloth-wrapped hose and its preparation method after composite extrusion of fluororubber and silicone rubber, a turbocharger hose made of fluororubber and oil-resistant silicone rubber, and an outer layer made of cloth-wrapped silicone, including a fluororubber inner layer, an oil-resistant silicone middle layer, and a silicone cloth tape outer layer; the inner layer is 0.4mm to 1.0mm thick, the middle layer is 1 to 3mm thick, and each layer of the silicone cloth tape is 0.5mm to 1.5mm thick. The preparation method of the invention includes the following steps: tube blank manufacturing process, reinforcement layer preparation, and vulcanization molding process. The present invention no longer uses the conventional aramid wire as the reinforcement layer, but uses a silicone cloth tape as the reinforcement layer. The aramid wire can only be wrapped with one layer, while the silicone cloth tape can be wrapped with multiple layers as needed. The hose adopts the process of first compound-extruding fluororubber and oil-resistant silicone, and then wrapping with silicone aramid cloth, which further improves the burst pressure and long-term pulse performance of the heavy-duty vehicle turbocharger hose and increases the service life of the heavy-duty vehicle hose. However, the invention does not disclose the specific process of wrapping. Summary of the invention

[0003] The cloth wrapping process in the existing cloth wrapping hose production process is completed by manual work, which has high labor intensity, low production efficiency and unstable cloth wrapping quality. In order to overcome these defects, the present invention provides a cloth wrapping hose cloth wrapping equipment with a high degree of automation, which can improve the consistency of cloth wrapping quality, reduce labor intensity and improve production efficiency.

[0004] The technical solution of the present invention is: a cloth-wrapped hose wrapping equipment, including a machine body, a rotating device, a supporting device, a cloth-wrapping core and a cloth-wrapping exhaust integrated device, the rotating device, the supporting device and the cloth-wrapping exhaust integrated device are all arranged on the machine body, the rotating device and the supporting device are relatively positioned, one end of the cloth-wrapping core is clamped on the rotating device, and the other end is rotatably connected to the supporting device, and the cloth-wrapping exhaust integrated device is slidably connected to the machine body. When the cloth-wrapped hose wrapping equipment is working, the semi-finished hose to be wrapped is put on the cloth-wrapping core, and the cloth-wrapping core is supported inside the semi-finished hose, so that the semi-finished hose remains straight, which is convenient for the implementation of subsequent cloth-wrapping and exhaust steps. One end of the semi-finished hose and the cloth-wrapping core is fixed on the rotating device, and the other end is supported by the supporting device. The rotating device drives the cloth winding core to rotate, and the cloth winding and exhausting integrated device moves along the axial direction of the cloth winding core. The relative motion between the cloth winding core and the cloth winding and exhausting integrated device is a spiral motion synthesized by rotational motion and linear motion. The cloth winding and exhausting integrated device winds the cloth tape on the semi-finished hose product in a spiral shape, and at the same time can drive out the air between the cloth tape and the cloth winding core to avoid bubbles in the cloth winding area, ensuring that the cloth tape and the cloth winding core fit smoothly and tightly.

[0005] Preferably, the cloth winding and exhausting integrated device comprises a movable seat, an exhausting pressure cylinder, a cloth tape reel and a cloth tape guide roller. The movable seat is slidably connected to the machine body, the exhausting pressure cylinder, the cloth tape reel and the cloth tape guide roller are arranged on the movable seat, the exhausting pressure cylinder is sleeved on the outside of the cloth winding core, and the cloth tape reel is used to install the cloth tape roll. When the cloth winding core and the semi-finished hose rotate, the cloth tape roll rotates on the cloth tape reel, the cloth tape on the cloth tape roll is pulled open and wound around the semi-finished hose. While the cloth is being wound, the exhausting pressure cylinder moves with the movable seat, gradually compressing the cloth tape from one direction, and pressing and wrapping the cloth tape while expelling the air between the layers of the cloth tape and the semi-finished hose.

[0006] As a preference, a slide rail parallel to the cloth winding core is provided on the machine body, and the movable seat is connected to the slide rail through a slider. The movable seat moves along the slide rail, and the exhaust pressure cylinder moves along the axial direction of the cloth winding core, and the cloth belt is pressed while the cloth is wound.

[0007] Preferably, the exhaust pressure cylinder includes an annular airbag and a cylinder body, wherein the annular airbag is embedded in the cylinder body, the annular airbag surrounds the outside of the cloth winding mold core, a notch is provided on the cylinder body for the cloth tape to pass through, and the cylinder body is fixed on the moving seat. The annular airbag is inflated to ensure a sealed fit with the surface of the cloth winding mold core. The annular airbag is a flexible component and needs to be supported by a rigid part. The cylinder body is connected to the moving seat while supporting the annular airbag, ensuring that the exhaust pressure cylinder can not only compress the cloth tape and expel the air between the cloth tape and the layers of the semi-finished hose, but also move with the moving seat as a whole.

[0008] Preferably, the support device comprises a support tube, a telescopic core column and a fluid cylinder. The support tube is fixed on the machine body, the telescopic core column is slidably embedded in the support tube and fits with the end of the cloth winding core, the fluid cylinder is fixed on the port of the support tube, and the piston rod of the fluid cylinder is connected to the telescopic core column. One end of the cloth winding core is fixed on the rotating device, and the other end is nested with the telescopic core column. The fluid cylinder pushes the telescopic core column against the cloth winding core and the semi-finished hose product, so that the cloth winding core and the semi-finished hose product are constrained in the radial and axial directions, and only have circumferential freedom, and can only rotate with the rotation of the rotating device.

[0009] Preferably, the fluid cylinder is an oil cylinder, which can generate relatively large pressure and stably support the cloth wrapping mold core.

[0010] As an alternative, the fluid cylinder is an air cylinder, which is relatively cheap and is conducive to cost control.

[0011] Preferably, the telescopic core column includes a connecting section and a cloth winding core matching section, the cloth winding core matching section is coaxially rotatably connected with the connecting section, the connecting section is slidably embedded in the support tube and connected to the fluid cylinder, and the cloth winding core matching section matches the cloth winding core. The connecting section is inserted into the support tube and guided by the support tube, so that the telescopic core column and the cloth winding core are precisely connected.

[0012] Preferably, the rotating device comprises a chuck and a driving mechanism, wherein the chuck is connected to the output end of the driving mechanism. The chuck can clamp the cloth winding core, so that the cloth winding core and the semi-finished hose obtain the rotational driving force from the rotating device.

[0013] The beneficial effects of the present invention are:

[0014] Easier to control the quality of cloth wrapping. The present invention completes the cloth wrapping process of the hose through the cooperation of the rotating device, the supporting device and the cloth wrapping exhaust integrated device. The speed, force and direction during the operation can be better maintained stable compared to manual operation, thereby reducing the influence of human factors and better maintaining the consistency of cloth wrapping quality.

[0015] Improve production efficiency. The invention has a high degree of automation and is easy to operate, and can greatly improve production efficiency.

[0016] Reduce labor intensity. The present invention has a high degree of automation and can replace manual labor to complete tedious operations, greatly reducing the labor intensity of operators. BRIEF DESCRIPTION OF THE DRAWINGS

The telescopic core column 402 and the other end of the semi-finished hose are simultaneously in contact with the step end face of the telescopic core column 402.

[0024] The working method of this cloth wrapping hose wrapping equipment is as follows:

[0025] Step 1. Pass the cloth winding core 2 through the semi-finished hose 6 to be wrapped with matching specifications, and then transfer the two together to the cloth winding hose wrapping equipment. Pass the cloth winding core 2 and the front end of the semi-finished hose 6 through the exhaust pressure cylinder 502 and clamp them on the chuck 301 of the rotating device 3. The rear end of the cloth winding core 2 is coaxially aligned with the telescopic core column 402. The telescopic core column 402 extends out and is inserted into the central blind hole at the end of the cloth winding core 2 to form a support for the end of the cloth winding core 2; install the cloth tape roll 506 on the cloth tape reel 503;

[0026] Step 2. Move the cloth wrapping and exhausting integrated device 5 along the slide rail 505 back to the zero position through the operation panel button, corresponding to the front end of the semi-finished hose 6, and the annular airbag 5021 is inflated;

[0027] Step 3. Pull out a little cloth tape from the cloth tape roll 506, and pass the end of the cloth tape through the quick-drying glue to fix it to the front end of the semi-finished hose;

[0028] Step 4. Start the rotating device 3 through the operation panel to drive the cloth winding core 2 and the semi-finished hose 6 to rotate. The cloth winding and exhausting integrated device 5 moves synchronously along the slide rail 505 under the drive of the driving screw, and the exhaust pressure cylinder 502 moves along the axial direction of the semi-finished hose 6. The relative movement of the semi-finished hose 6 and the cloth winding and exhausting integrated device 5 is a spiral movement synthesized by a rotational motion and a linear motion. The annular airbag 5021 fully fits the semi-finished hose 6, and while moving axially, it presses the cloth tape that has just been wrapped around the semi-finished hose 6. In this way, the cloth winding and exhausting integrated device 5 wraps the cloth tape around the semi-finished hose 6, and at the same time, the air between the cloth tape and the semi-finished hose 6 can be driven out to avoid bubbles in the cloth winding area, ensuring that the cloth tape and the cloth winding core 2 fit smoothly and tightly;

[0029] Step 5. Stop the machine, unlock the cloth wrapping core 2 and the rear hose after cloth wrapping by the chuck 301, remove the cloth wrapping core 2 and the rear hose after cloth wrapping, perform offline cutting on the rear hose after cloth wrapping, and cut off the small section at the front end of the rear hose after cloth wrapping that is not wrapped because the exhaust pressure cylinder 502 occupies the position.

[0030] Embodiment 2:
