Description

Technical field:

[0001] The invention relates to the technical field of wool strip threading devices, and in particular to a wool strip grabbing mechanism for doors and windows and an automatic wool strip threading machine. Background technology:

[0002] The wool strip is made of high-quality random polypropylene as the raw material, and is synthesized with siliconized polypropylene yarn and polypropylene film. The wool strip is widely used in window frames and sliding doors, mainly to block gaps and increase the tightness between the gaps of doors and windows. It has the functions of heat insulation, shock reduction and noise reduction, and preventing mosquitoes from entering the room.

[0003] The traditional method of installing wool strips is mainly manual or manual with simple tools. Manual installation is not only labor-intensive, time-consuming and labor-intensive, but also has low efficiency in threading. The threading process seriously affects the entire door and window production progress.

[0004] In order to improve the installation efficiency of wool strips, reduce the labor intensity of manual labor, make the design of wool strip threading equipment more reasonable and perfect, various attempts have been made in the prior art to try to make the overall structure of the wool strip threading device more reasonable. However, there are always some unsatisfactory aspects. For example, Chinese Patent No. 200920049992.1 discloses a fully automatic wool strip threading machine. The technical solution realizes the installation of wool strips in the door and window grooves through the cooperation of a wool strip guiding mechanism, a slidable head, a wool strip threading mechanism and a wool strip pressing mechanism. The design of the wool strip threading mechanism in the technical solution mainly adopts two cylinders and two back-to-back threading claws to press the wool strips into the grooves first and then move the threading strips. Although the solution can also The purpose of strip feeding is achieved, but there are some shortcomings. First, pressing the front end of the wool strip into the groove by the strip feeding claw can easily cause the bottom plate of this part of the wool strip to deform or bend, or even cause the technical problem of not being able to be pressed into the groove. The deformation or bending of the bottom plate of the wool strip will have a great impact on the sealing of the later doors and windows. Second, due to the back-to-back design of the two strip feeding claws, this solution can only process the situation where the distance between the two grooves of the doors and windows is greater than the thickness of the two strip feeding claws, and the thickness of the strip feeding claws cannot be too thin. If the thickness of the strip feeding claws is thin, it is easy to be deformed by impact, affecting the quality of the strip feeding; third, this technical solution does not have a strip cutting device, and needs to be cut manually; fourth, this technical solution has no adjustment device and cannot be applied to strip feeding of various door and window models.

The profile here is generally a sliding sash or a window frame.

[0053] During operation, the profile is first placed on the workbench 2 and aligned with the reference limit plate 501, and then the clamping cylinder 502 operates to clamp the profile, and then the two wool strips are respectively inserted into the guide groove A312 and the guide groove B314 (manual insertion is required at the beginning, and no manual insertion is required after normal operation. The wool strips here are generally a whole plate, and the whole plate of wool strips can be supported by the placement rack), and then the strip insertion drive motor 604 operates to drive the wool strip grabbing mechanism 1 to move to the guide groove position. During the movement, the grab plate A1032 and the grab plate B1042 are closed and located in the middle of the two guide grooves. When they move to the specified position between the two guide grooves, the drive cylinder 1061 is actuated to drive the grab plate A1032 and the grab plate B1042 apart, and at the same time, the spring A1076 and the spring B1086 are compressed. Under the action of this pressure, the grab plate A1076 and the grab plate B1086 are aligned and separated to both sides, and the barbs 105 on the grab plate A1076 and the grab plate B1086 respectively penetrate into the guide groove A312 and the guide groove B314 to grab the two wool strips, and then the wool strip threading drive motor 604 starts to work and rotates in the opposite direction, and then drives the wool strip grabbing mechanism 1 to move toward the profile direction through the gear rack transmission. During the movement, since the guide groove is aligned with the wool strip threading groove on the profile and the guide block fits with the end of the profile, the wool strip can directly enter the wool strip threading groove of the profile, and then drive the wool strip to penetrate into the profile to achieve threading. When the wool strip reaches the specified position, the cutting drive cylinder works to drive the cutter to move downward quickly into the cutting groove to cut the wool strip, thereby achieving one-time threading of the wool strip, and batch threading can be achieved by repeating the cycle. The automatic threading machine of the present application has the advantages of reasonable structural design, complete functions, high degree of automation, high threading efficiency, and high threading quality.
