Description

Technical Field

[0001] The utility model relates to the technical field of door and window processing equipment, in particular to a cantilever door and window glue spraying machine. Background Art

[0002] At present, the doors and windows used in my country's buildings are mainly aluminum-plastic windows, which are composed of glass and profiles. During the processing, sealant needs to be applied between the glass and the profiles. In order to improve production efficiency and reduce labor intensity, glue machine equipment has been developed. Compared with the original manual glue method, it has the advantages of high efficiency and high speed, so it is widely used. For example, CN217342137 U discloses a utility model patent for a positioning mechanism of a glue machine for doors and obtained by the applicant, which includes a base, a glue machine head movable relative to the base, and at least 2 sets of brackets and a positioning mechanism. The positioning mechanism clamps and positions the doors and windows placed on the bracket, and the glue machine head can perform glue operations on the doors and windows placed on the bracket. The support rack and the positioning mechanism are arranged on the base. The support rack of group 1 includes at least two support rods connected to the base at one end. The fork of a forklift can enter between the two support rods so as to transport the doors and windows stacked on the support rods. Auxiliary positioning rods are arranged on the base and on both sides of the positioning rack, and the lower ends of the auxiliary positioning rods are connected to the base. The front side of the auxiliary positioning rod is coplanar with the front side of the positioning plate. In the glue machine of this technical solution, the doors and windows can be stacked on the support rods. When the stacked doors and windows reach the set height or number, the fork of the forklift is inserted between the two support rods, and the stacked doors and windows are lifted by the fork. The forklift transports the doors and windows as a whole to the warehouse and waits for the glue to solidify. Since the doors and windows have good overall rigidity after being stacked, they are not easy to deform during transportation, and there are no defects such as wrinkles on the glue surface after the glue is solidified, and the quality is good. By setting up multiple groups of support racks, the doors and windows on multiple stations can be glued in turn, thereby improving the glue efficiency.

[0003] However, the gluing machine of the above technical solution is not suitable for door products, especially indoor doors. Indoor doors usually have only single-layer glass or at most two-layer glass. Therefore, the frame profile used has a small cross-sectional size, a thin profile thickness, and a long length, generally more than 2.5 meters. After framing, the rigidity is small and it is easy to deform. When placed on the existing gluing machine for gluing, only one side is against the positioning plate. During gluing, the frame is easy to loosen and deform, and the four corners are no longer 90 degrees. The rectangular door frame will become a parallelogram, and the gluing quality is difficult to guarantee. When the deformation is serious, it will not only affect the automatic edge patrol of the edge patrol mechanism on the gluing machine head, but also make the glue gun nozzle unable to approach the workpiece, resulting in the glue gun being unable to glue along the normal gluing trajectory. Summary of the invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a positioning mechanism for a door glue gun to solve the problems existing in the background technology.

[0005] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:

[0007] By adopting the above technical scheme, doors and windows can be stacked on the gluing machine, the first door and window is placed on the gluing machine, and the door and window clamping device clamps and positions the door and window on the gluing machine. After the gluing is completed, the door and window clamping device moves up, and the second door and window is placed on the first door and window. The door and window clamping device clamps and positions the second door and window. After the gluing is completed, the door and window clamping device moves up again, and then the third door and window is placed, and so on. After the stacked doors and windows reach the set height or number, the forklift lifts the stacked doors and windows and transports them to the warehouse as a whole to wait for the glue to solidify. Since the doors and windows have better overall rigidity after being stacked, they are not easy to deform during transportation, and there are no defects such as wrinkles on the glue surface after the glue is solidified, and the quality is good.
