Description

Technical Field

[0001] The invention relates to the field of shape-keeping tube production devices, and in particular to a coilable shape-keeping tube production device. Background Art

[0002] A conformal tube is a coilable tube that maintains its round shape both during storage and use. It is composed of a lining layer rubber hose and a skeleton layer strip blank, and is mainly used for the transmission of fluids such as liquids and gases.

[0003] In the prior art, the production of conformal tubes is usually divided into three processes, namely: extruding the lining layer hose, the bonding layer glue and the anti-leakage layer hose by a double-layer co-mold; weaving the skeleton layer strip blank by a circular loom; manually introducing the lining layer hose into the skeleton layer strip blank, and using steam heating to make the bonding layer glue bond the skeleton layer and the anti-leakage hose together.

[0004] However, the prior art has the following problems: the skeleton layer strip blank is pulled by a clamping roller during weaving, and the polyester monofilament is squeezed into a flat shape. The polyester monofilament is then heated and softened by steam on the production line and set into a round shape, and then introduced into the inner lining layer hose. However, due to the inconsistent softening temperatures of the adhesive layer glue, the anti-leakage layer hose and the polyester monofilament, the high temperature of the steam will cause the adhesive layer glue to overflow from the skeleton layer, affecting the product appearance and bonding performance, and the anti-leakage layer hose will decompose and cause leakage, thereby causing product production errors. The low temperature polyester monofilament cannot be completely softened to support the round shape, and the shape-keeping tube is elliptical, which cannot meet customer needs. At the same time, when the inner lining layer hose is introduced, it is easy to cause the inner lining layer hose to rotate, be abraded, be worn, and foreign objects to penetrate between the inner lining layer hose and the skeleton layer strip blank, resulting in defective products. In addition, since the steam needs to maintain a certain temperature during the production process, the investment cost is high, the energy consumption is high, and there are also safety hazards. The length of the production line needs to be designed and invested according to the length required by the customer, and the length of the product has great requirements on the production line and factory. Summary of the invention

[0006] In one embodiment, each group of the air ducts includes a first air duct and a second air duct, the first air duct is located above the second air duct, and one end of the first air duct is connected to the second air duct.

[0007] In one embodiment, the heating wire is wound around the first air duct, and the heating component is aligned with the first air duct.

[0008] In one embodiment, the control structure includes a first gear, a gear box, a second gear and a chain, the upper end of the chain is connected to the circular loom, and the lower end passes through the first gear and the second gear in sequence and enters the gear box to be connected to the traction structure.

At least two groups of guide rails arranged in parallel up and down are provided between the first gear and the second gear. Each group of guide rails is composed of at least two horizontally arranged guide rails. At least two sections of bushings are sleeved on each group of guide rails. A screw is provided between the two groups of guide rails.

[0010] In one embodiment, the traction structure is composed of at least two crawler traction machines, and the conformal tube passes through a gap between the crawler traction machines.

[0012] In one embodiment, a storage plate is further provided between the extruder and the circular loom.

[0013] In one embodiment, the optimal operating temperature of the high temperature oven is 100°C-135°C.

[0053] Table 2 High temperature oven temperature test data 2

[0054]

[0055]

[0058] It can be seen from Tables 1 to 3 that the performance parameters in Table 3 are the best, and the optimal operating temperature range of the high temperature oven 14 is 100° C.-135° C. When the temperature of the high temperature oven 14 is higher than 135° C., the material performance will be reduced.
