Description

Material box and automatic feeding device

The technical field is as follows:

the utility model relates to a door and window processing equipment technical field, concretely relates to magazine and automatic feeding.

Background art:

the fixing piece (also called connecting piece or mounting piece or connecting piece) is one of the essential parts in the door and window installation, and mainly plays a role in fixing the door and window on the wall body. In order to improve the processing efficiency of doors and windows, the fixing sheet is generally required to be installed on the door and window profile in advance. The installation of stationary blade in the past mainly relies on the manual work to accomplish, makes the mounted position mark on door and window section bar in advance during the installation, places the stationary blade on door and window section bar according to the mark, then carries out the nailing with electric screwdriver, and this kind of mounting means is not only intensity of labour big, wastes time and energy moreover, is seriously restricting the machining efficiency of door and window. In order to realize high-efficiency and high-precision installation of the fixing sheet, mechanical installation must be realized, and the main technical difficulties for realizing the mechanical installation include two: firstly, automatic nailing is realized; secondly, realize the autoloading of stationary blade. Wherein automatic nailing technical development is mature relatively, and current numerical control nailer can realize the accurate operation to nailing position, automatic screw and automatic screw tightening, can satisfy the processing demand. However, the problem of how to realize the automatic feeding of the fixing sheets always troubles relevant scientific researchers.

Various attempts have been made in the prior art to achieve automatic feeding of the anchor sheets, however, there are always some unsatisfactory aspects, for example, chinese patent application No.: CN201821050331.6 discloses a scheme for directly and rapidly mounting a fixing sheet on a nailing mechanism by using the magnet principle, and then a numerical control nailing machine drives the fixing sheet to directly nail a door and window profile, so as to realize semi-automatic feeding of the fixing sheet, but still require manual feeding; still disclose a mechanism (be called for short horizontal feeding mechanism) that can realize carrying out autoloading along stationary blade length direction as prior art, concrete structure is shown in fig. 11, this horizontal feeding mechanism is including the horizontal pay-off passageway of horizontal setting, be provided with the horizontal pay-off magazine of placing the stationary blade on the horizontal pay-off passageway, horizontal pay-off magazine is equipped with along stationary blade length direction one side and pushes away the material mouth, the opposite side is equipped with the discharge gate, the size of discharge gate can only supply a stationary blade to pass through, it drives actuating cylinder to be equipped with horizontal pay-off in a material mouth one end, this horizontal feeding mechanism can realize the pay-off of stationary blade, but there is: firstly, only straight fixing pieces can be fed, but not bent fixing pieces, the existing fixing pieces are divided into two types, namely straight fixing pieces and bent fixing pieces, and as shown in fig. 12, the straight fixing pieces mean that the whole surface is flat; as shown in fig. 13, the bent fixing piece is bent at about 1/4 of the length of the fixing piece and is divided into a straight line section and a bent section, wherein the length of the straight line section is greater than that of the bent section, the straight line section is parallel to the surface of the bent section but not in the same plane, and the bent fixing piece is mainly used for facilitating the rotation of the fixing piece for installation during installation, so that the bent fixing piece is more widely applied; secondly, the transverse conveying is adopted, so that the transverse length of the whole structure is too long, the use is very inconvenient, and the structure is not compact enough; thirdly, because the transverse conveying distance is far away, the length of the material pushing plate is long, the material pushing plate is easy to deform after being used for a long time, and finally the clamping is caused, even the fixing sheet is popped out.
