Description

Rotary fine adjustment mechanism of rear co-extrusion die head

Technical Field

The utility model relates to a rotatory fine-tuning of crowded die head altogether behind the plastic section.

Background

The post-plastic co-extrusion production process is a continuous and stable production process, factors influencing the production process are many, and the control of the position of an adhesive tape is a very important aspect. As is known, the post-plastic co-extrusion molding production process is a dynamic process, which involves a wide range of mold design, and a repeated debugging process is needed in the process from the completion of the manufacturing to the production of qualified products. In the process, the section bar may be turned over by a slight angle, and production practices show that the angle is usually within 2 degrees, and even the 2-degree deviation can cause the adhesive tape to be attached to a position with a large deviation and not to be tightly attached, so that the adhesive tape is attached to the accurate position of the section bar, which is a very important aspect.

In the extrusion molding production process of the existing mold, because the customer mostly selects the adjustable back co-extrusion mold head, the position can only be adjusted from top to bottom and from left to right by adjusting the mold head, but the position to be attached to can not be accurately attached to the adhesive tape after the mold head rotates by an angle.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, convenient and flexible operation, low cost and high efficiency

The back co-extrusion die head rotation fine-tuning mechanism capable of realizing the rotation of the on-line die head realizes the stability and the safety of the system.

In order to solve the problem, the utility model discloses rotatory fine-tuning of back crowded die head altogether: including crowded die head, guide rail and lower rail altogether, wherein: the guide rail is clamped on the lower guide rail; the first screw rod sequentially passes through the first screw rod pressing plate, the upper end of the guide rail and the sliding block and is fixed through a screw rod nut; the rear co-extrusion positioning square key is respectively connected with the adjusting block through an upper adjusting screw and a lower adjusting screw, the adjusting block is fixedly connected with the sliding block, and the first rear co-extrusion die head, the second rear co-extrusion die head and the rear co-extrusion positioning square key are fixedly connected with the sliding block through hoisting screws; the second screw rod sequentially passes through the second screw rod pressing plate and the bottom end of the guide rail and is fixed through a screw rod nut.

By adopting the technical scheme, the die head can rotate within an angle of 2 degrees in the square key groove around the post co-extrusion positioning square key only by adjusting the screw on the adjusting block.

Preferably, the first screw rod and the second screw rod are trapezoidal screw rods.

To sum up the beneficial effects of the utility model are that: adopt the technical scheme of the utility model

The post-coextrusion die head rotation fine-tuning mechanism has the advantages of simple structure, convenience and flexibility in operation, low cost and high efficiency, and can realize the rotation of the on-line die head, so that the die production process is more stable and safer.
