Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic hose processing, in particular to an aluminum-plastic hose clamping device for a shoulder injection machine. Background Art

[0002] During the shoulder injection process of the aluminum-plastic hose, the aluminum-plastic hose is put on the core rod, and the aluminum-plastic hose is pressed down by the pressure plate on the cylinder to flatten the upper end of the aluminum-plastic hose and the upper end of the core rod, and then the tube head part is pressed into shape at the upper end of the aluminum-plastic hose by the pressing die. Since the aluminum-plastic hose is prone to dimensional deviation during the cutting process, the die is pressed down during the shoulder injection process, and the aluminum-plastic hose will retreat under pressure, causing cracks between the tube head part and the aluminum-plastic hose, affecting the quality of the product.

[0014] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.

[0015] like Figure 1 and Figure 2 As shown, a clamping device for an aluminum-plastic hose of a shoulder injection machine comprises a core rod 1, a mounting seat 2 is arranged below the core rod 1, the mounting seat 2 is connected to the top of the turntable of the shoulder injection machine through a bracket, a mounting hole is processed on the mounting seat 2, an elastic clamp 3 is installed in the mounting hole, a clamping opening is processed in the middle of the elastic clamp body 3, the core rod 1 is installed in the clamping opening, wherein a threaded column 4 is arranged in the clamping opening of the elastic clamp body 3, the bottom of the core rod 1 is screwed on the threaded column 4, a plurality of release grooves 5 are evenly distributed on the body of the elastic clamp 3 around the clamping opening, a lifting cylinder 6 is arranged below the elastic clamp body 3, a piston end of the lifting cylinder 6 is connected to a lifting sleeve 7, the lifting sleeve 7 faces the elastic clamp body 3, an avoidance hole 8 is opened below the mounting hole of the mounting seat 2, the avoidance hole 8 avoids the piston end of the lifting cylinder 6, so that the lifting sleeve 7 can contact with the bottom of the elastic clamp body 3.

[0016] In this embodiment, an installation groove 9 is processed around the bottom of the elastic clamp body 3, and a clamping ring 10 is installed on the mounting seat 2. The clamping ring 10 adopts a half structure and is fixed to the surface of the mounting seat 2 by screws. The periphery of the clamping ring 10 extends into the installation groove 9 to clamp the elastic clamp 3. A tube pressing cylinder 11 is arranged above the core rod 1, and the piston end of the tube pressing cylinder 11 is connected to a pressing plate 12. When the shoulder injection machine is working, the aluminum-plastic hose is sleeved on the core rod 1. After it is rotated into place, the piston end of the lifting cylinder 6 rises and slightly stretches the elastic clamp body 3. After the piston end of the tube pressing cylinder 11 controls the pressing plate to press the aluminum-plastic hose down into place, the lifting cylinder 6 is released, and the elastic clamp body 3 is reset to clamp the tail of the aluminum-plastic hose to prevent the aluminum-plastic hose from moving.

[0017] The piston of the lifting cylinder 6 is connected with a limit plate 13, which is fixed by a set screw on the side. The limit plate 13 controls the extension amount of the piston of the lifting cylinder 6 to prevent the elastic clamp body 3 from opening excessively and being unable to reset.

[0018] The present invention is not limited to the described embodiments. Those skilled in the art may make some modifications or changes without departing from the spirit and scope of the present invention, that is, within the scope of disclosure. Therefore, the scope of protection of the present invention shall be subject to the scope defined in the claims.
