Automatic spring rotary-cutting and inserting machine for preparation of film-suspended insulating glass film stretching frame

Abstract

An spring rotary-cutting and inserting machine for preparation of a film-suspended insulating glass film stretching frame comprises a spring feeding mechanism, a spring conveying mechanism, a spring taking mechanism, a rotary-cutting mechanism, a frame moving mechanism, a propping mechanism and a work bench, wherein spring feeding, conveying and taking are performed, then a rotary arm in the rotary-cutting mechanism rotates to drive a spring insertion head which is mounted on the rotary-cutting mechanism and clamps a spring to perform circular motions, so that an expansion ring on the last circle at the bottom of the spring is squeezed in the tangential direction of the circumference to become narrow and then enters flared ports in the bottom of the clamping groove of the film stretching frame via the bottle neck of a clamping groove of the film stretching frame, and the expansion ring recovers elasticity, becomes wide and is clamped and positioned in the flared ports. The rotary head of the spring taking mechanism rotates by 360 degrees, so that fractures at the bottoms of springs of the spring taking mechanism face the same direction, and the fractures of bottom rings of the inserted springs in the film stretching frame keep at the same angle. Damage of spring insertion to a sectional material of the film stretching frame is reduced, so that all the fixed springs in the film stretching frame keep in a certain direction and at a certain angle and are distributed well linearly.

Description

technical field [0001] The invention relates to the field of green energy-saving buildings, in particular to an automatic rotary cutting and inserting spring machine for preparing a film-suspended hollow glass stretch film frame. Background technique [0002] Green and energy-saving buildings have higher and higher requirements on the optical and thermal performance of the insulating glass used in the outer enclosure. The insulating glass with two or three hollow layers composed of plastic films that block ultraviolet rays is hung in the middle, which has better performance. U value. [0003] Foreign technicians invented the inner suspension film hollow glass (US Patent No. 5237787) that uses springs as the film element and fixes the film on the surrounding frame of the glass through ultrasonic welding technology, and realized the industrial production and production of the product in the 1990s. Commercial applications, and proved to be an ideal choice for green energy-savi...

AI Technical Summary

Problems solved by technology

Since the spring is mostly made of piano wire or stainless steel, the stretch film frame is mostly made of aluminum alloy, and some special materials such as engineering plastics are also used. When the bottom expansion ring is inserted into the stretch film frame slot, it is easy to cause damage to the profile. Damage to the bottom enlarged coil of the spring, resulting in deformation

The original method of inserting the spring basically adopts the processing method of punching, especially the damage to the enlarged ring at the bottom of the spring is serious, and the hidden danger of damage to the profile is exacerbated

Manual and special tools are used to operate the compression spring, although the damage to the profile can be effectively avoided, and the fracture of the bottom expansion ring can also be manually adjusted, but the labor intensity is too high and the production efficiency is too low

There are also methods of inserting the bottom expansion ring into the card slot, or imitating the manipulator of the artificial compression spring, but the action is too complicated and the production tempo is too slow, which restricts the production tempo and efficiency of the entire suspension film insulating glass
