Loss prevention frame pressing machine with corner pressing assemblies

Abstract

The invention discloses a loss prevention frame pressing machine with corner pressing assemblies. The loss prevention frame pressing machine comprises a machine table, a pair of short edge propelling mechanisms and a pair of long edge propelling mechanisms, wherein the short edge propelling mechanisms and the long edge propelling mechanisms are arranged on the machine table; each short edge propelling mechanism comprises a short edge propelling frame and a pair of corner pressing assemblies of a symmetric structure; the outer sides of the corner pressing assemblies abut against the inner sides of the corresponding long edge propelling mechanisms; the short edge propelling frames are fixedly provided with lateral moving air cylinders used for controlling the corner pressing assemblies to move; each lateral moving air cylinder comprises a cylinder body with a first air inlet and a second air inlet and a spindle with the tail end connected with the corresponding corner pressing assembly; the second air inlets get close to the tail ends of the spindles relative to the first air inlets; the second air inlets are closed through plugs. The constant air pressure difference of the two sides of the lateral moving air cylinders is used for providing resilience force, common air cylinders are used as air springs which are inflated only in work, and therefore the upper limit of pressure of long edge propelling air cylinders is convenient to control, shock of the corner pressing assemblies is relieved, and the service life of the corner pressing assemblies is prolonged.

Description

technical field [0001] The invention relates to the technical field of framing equipment, in particular to a frame pressing machine for preventing damage caused by movement and vibration of a pressing angle assembly. Background technique [0002] A frame pressing machine is a device that can be used to assemble glass and frames. Whether the splicing area of ​​the framed product is tight will seriously affect the appearance of the product. In order to tighten the connection position between the frames, the frame pressing machine needs to press the corners of the frame with the corner pressing assembly and then apply force horizontally. There are two problems in this: ①The corner pressing assembly needs to be mobile because it needs to avoid the movement of the glass. The structure, the press angle assembly finds a suitable working position in the splicing area to make the press frame normally complete; ②The driving of the press angle assembly too fast will cause some collisi...

AI Technical Summary

Problems solved by technology

In order to tighten the connection position between the frames, the frame pressing machine needs to press the corners of the frame with the corner pressing assembly and then apply force horizontally. There are two problems in this: ①The corner pressing assembly needs to be mobile because it needs to avoid the movement of the glass. structure, the pressure angle assembly can find a suitable working position in the splicing area to make the pressure frame normal; ② If the pressure angle assembly is driven too fast, some collisions will occur, which may cause rapid wear and tear on the cylinder components on the pressure angle assembly
