Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production equipment, in particular to a hydroentangling machine with adjustable hydroentangling heads. Background Technique

[0002] In the non-woven fabric manufacturing industry, the hydroentangling machine is a key production equipment; it reinforces the fiber web through high-pressure water flow, which can enhance the structural strength and stability of the fiber web, while maintaining the softness and air permeability of the material, so as to produce non-woven fabric products with high strength and specific properties. The market demand for non-woven fabrics is becoming increasingly diversified, and different non-woven fabric products often require different specifications of hydroentangling holes to achieve the best hydroentangling effect. For example, fine fibers require smaller nozzle apertures and softer hydroentangling pressures to avoid fiber breakage and meet specific physical properties and application requirements. However, the hydroentangling machines currently on the market usually have hydroentangling heads with fixed specifications, that is, the size, shape and arrangement of the hydroentangling holes on the nozzle plate are fixed. Due to the fixed specifications of the hydroentangling heads, it is difficult to quickly adapt to the changes in product specifications. When switching different types of non-woven fabrics, it is necessary to replace the hydroentangling heads, resulting in low production efficiency. Content of the Utility Model

[0003] In order to solve the problems in the above background technique, the utility model provides a hydroentangling machine with adjustable hydroentangling heads.

[0004] The solution adopted by the utility model to solve its technical problems is: a hydroentangling machine with adjustable hydroentangling heads, which includes a frame, at least one hydroentangling mechanism arranged on the frame and a high-pressure water supply mechanism. The hydroentangling mechanism includes a shell erected on the frame, a water inlet cavity arranged in the shell and communicated with the high-pressure water supply mechanism, and a high-pressure water outlet cavity communicated with the water inlet cavity. The cross-section of the high-pressure water outlet cavity is circular. A bottom groove is arranged at the bottom of the high-pressure water outlet cavity. An arc-shaped water needle plate is arranged in the high-pressure water outlet cavity and fits against the bottom surface of the high-pressure water outlet cavity. Multiple groups of water needle holes are arranged at intervals on the arc-shaped water needle plate. The aperture sizes of each group of water needle holes are different. The hydroentangling mechanism further includes a driving mechanism for driving the arc-shaped water needle plate to rotate along the high-pressure water outlet cavity to switch different aperture water needle holes corresponding to the bottom groove.

[0005] By adopting the above technical solution, the arc-shaped water needle plate is longitudinally provided with multiple groups of water needle holes, and the aperture sizes of each group of water needle holes are inconsistent, and it can fit and match with the circular high-pressure water outlet cavity. The driving mechanism can drive the arc-shaped water needle plate to rotate axially in a small amplitude along the circular cavity, and can switch the properly arranged water needle holes to align with the bottom groove, so as to adapt to the production of various non-woven fabrics.

[0006] Further, the driving mechanism includes a driving motor disposed on one side of the hydroentangling mechanism, a rotating main shaft connected to the driving motor, and a connecting plate fixedly connected to the side end of the arc-shaped water needle plate, and the other side of the connecting plate is fixedly connected to the rotating main shaft.

[0007] By adopting the above technical solution, the rotational force of the driving motor is transmitted to the connecting plate, thereby driving the arc-shaped water needle plate to rotate.

[0008] Further, a flow equalizing chamber is also provided between the water inlet chamber and the high-pressure water outlet chamber, and a flow equalizing plate is further provided in the flow equalizing chamber. The top of the flow equalizing chamber is communicated with the water inlet chamber, and the bottom of the flow equalizing chamber is communicated with the high-pressure water outlet chamber.

[0009] By adopting the above technical solution, the water flowing in from the water inlet chamber can be balanced to ensure uniform distribution of the water flow.

[0010] Further, the high-pressure water supply mechanism includes a high-pressure water pump and a water inlet pipe connected to the high-pressure water pump and inserted into the water inlet chamber, and a pressure regulating valve for controlling the water pressure is further provided on the water inlet pipe.

[0011] By adopting the above technical solution, the high-pressure water pump can generate high-pressure water flow, which is sprayed onto the non-woven fabric material through the water needle plate, and the water pressure control valve can adjust the water pressure according to requirements.

[0012] Further, a filter cartridge net for filtering water is provided in the water inlet chamber.

[0013] By adopting the above technical solution, the water entering the hydroentangling mechanism can be filtered to avoid clogging the water needle holes.

[0014] In summary, the beneficial effects of the present utility model are as follows: By designing the high-pressure water outlet chamber as a circular chamber, and designing the water needle plate as an arc shape adapted thereto, and longitudinally arranging multiple groups of water needle holes, the aperture sizes of each group of water needle holes are inconsistent. The driving motor can drive the arc-shaped water needle plate to rotate axially along the circular chamber to switch the appropriately arranged water needle holes to align with the bottom groove, so as to be suitable for various non-woven fabric productions.
