Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 2.

The embodiment has the specific structure that: including the equipment body, workstation 1 has on the equipment body, is provided with the bed frame that is used for placing the sheet on workstation 1, has seted up on the bed frame and has adsorbed hole 30, and the horizontal slip is provided with heating element 2 that is used for heating the sheet on workstation 1, is provided with on workstation 1 to be used for making the sheet when heating to the suction fan 10 of adsorbing hole 30 internal stretching.

The heating component 2 is a common sheet heater on the market, and the heating of the heating plate is realized by electrifying. The heating assembly 2 is connected with the frame body on the workbench 1 through a rail which is installed to be slidable. When the sheet needs to be heated, the cylinder or the motor controls the heating assembly 2 to move to the position right above the sheet.

When heating element 2 heats the sheet, can make the sheet soften, then bleed through suction fan 10, the sheet above adsorbing hole 30 can be towards adsorbing hole 30 below activity, and adsorbing hole 30 is as a mould, realizes at last that the sheet becomes the structure that has the convex mirror from a flat plate.

The bed frame includes flitch 3 and arranges the frame on flitch 3 in, and flitch 3 and frame can be dismantled the connection, adsorb on the flitch 3 is arranged in to the hole 30, the frame includes frame 41 and inside casing 42, and inside casing 42 arrange in frame 41 and with frame 41 sliding connection, all be equipped with the graphite strip that reduces the frictional force that produces when both slide on both mutually contradicted of inside casing 42 and frame 41, all set up a plurality of locating holes of interconnect on frame 41 and the inside casing 42.

The inner frame 42 is provided with a clamping groove for inserting the sheet, and the workbench 1 is provided with an ejection device for ejecting and flying the sheet in the inner frame 42.

The ejection device is used for automatically separating the internally formed corner mirror from the inner frame 42. The concrete structure is as follows: the device comprises a movable part and a fixed part, wherein the movable part comprises extension springs 51 arranged at two sides of an outer frame 41 and a push-pull air cylinder 52 driving an inner frame 42 to move relative to the outer frame 41.

A fixing member: the device comprises a static fixing unit for locking the position of the inner frame 42 when moving backwards and a dynamic fixing unit which is arranged on the moving path of the inner frame 42 and used for limiting the inner frame 42 to move forwards continuously.

The static fixing unit includes: the lifting cylinder 61 and the positioning pin rod 62, the positioning pin rod 62 is connected to the output end of the lifting cylinder 61, and the lifting cylinder 61 controls the positioning pin rod 62 to extend into the positioning hole to fix the position of the inner frame 42;

the dynamic fixing unit comprises an anti-collision table 71 fixed on the workbench 1, and a rubber pad is arranged on the end face, which is used for being collided by the inner frame 42, of the anti-collision table 71. The inner frame is also provided with an anti-impact rubber pad 421

The side of the outer frame 41 is provided with a sliding opening, the two sides of the inner frame 42 are provided with connecting parts 420 extending out of the sliding opening, the workbench 1 is provided with a connecting rod 11, the connecting rod 11 and the connecting part 51 are on the same axis, one end of the extension spring 51 is connected with the connecting part, and the other end of the extension spring is connected with the connecting rod.

The specific working principle is as follows: before a PC material of a thermoforming machine is made into a corner mirror, a sheet is inserted into a clamping groove (the width of the clamping groove is larger than the thickness of the sheet) of the inner frame 42, then the sheet is pushed against the inner frame 42 by a push-pull air cylinder 52 to slide towards the rear part of the inner frame 42, namely, the sheet advances towards the inner frame 41, in the process, an extension spring 51 is stretched along the moving direction of the inner frame 42, and after the sheet reaches a set position, a lifting air cylinder 61 drives a positioning pin rod 62 to move towards the outer frame 41, so that the positioning pin rod 62 penetrates into a positioning hole of the inner frame 42 from the positioning hole of the outer frame 41, and the locking of the position of the; then the push-pull air cylinder 52 controls the output end to return to the initial state; then the heating component 2 heats the sheet and then forms the sheet by matching with the suction fan 10 and the adsorption hole 30.

After the sheets are formed, the lifting cylinder 61 controls the positioning pin rod 62 to be rapidly pulled out from the positioning hole, the inner frame 42 is rapidly pulled forward to move under the influence of the elastic restoring capability of the tension spring 51 until the inner frame 42 collides with the anti-collision table 71, and when the inner frame collides with the anti-collision table 71, the sheets in the inner frame 42 fly out of the clamping grooves due to the influence of inertia. For the convenience of storage, a storage net is provided on a path along which the sheet is ejected and flown out.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art should be able to make general changes and substitutions within the technical scope of the present invention.
