Description

Technical Field

[0001] The invention relates to the field of door and window processing equipment, in particular to an automatic strip threading machine for sealing strips of door and window profiles. Background Art

[0002] Regarding the automatic insertion equipment of door and window sealing strips, the prior art uses two clips to clamp the hair of the sealing strip to pull it so that the bottom plate moves in the groove of the door and window profile. Its defects are: 1. The two clips are used to clamp the hair of the sealing strip to pull it so that the bottom plate moves in the groove of the door and window profile. The width of the clip is fixed, but the groove width of the door and window profile is different, and the hair bundles of the sealing strip are of different heights. Once the clip cannot effectively clamp the hair bundle, the sealing strip pulling will fail. If the clip is replaced each time for different door and window profile groove widths, high mold costs will be incurred and work efficiency will be reduced due to the replacement of the clip. Moreover, in actual use, the height of the hair bundle of the sealing strip is only 3mm, and the clip cannot be effectively clamped and pulled at all. 2. The moving head for installing the clip is above the equipment platform, and its high-speed movement will hit the workers, which poses a certain safety hazard. Summary of the invention
