Description

Technical Field

[0001] This utility model relates to the technical field of door and window sealing strip installation equipment, and in particular to a door and window sealing strip installation equipment. Background Technology

[0002] In the manufacturing and installation of building doors and windows, the installation of door and window sealing strips is a crucial process. Door and window sealing strips not only enhance the sealing performance of doors and windows, effectively blocking the intrusion of dust, rainwater, and noise, but also improve their thermal insulation and heat insulation effects, significantly impacting the overall energy efficiency of buildings. Traditional door and window sealing strip installation mainly relies on manual operation; however, this method has several drawbacks. Firstly, manual installation is inefficient and easily affected by the worker's skill level and work condition, leading to inconsistent installation quality. Secondly, manual installation makes it difficult to guarantee the uniformity and stability of the sealing strip installation, potentially resulting in insecure installation and poor sealing, thus affecting the performance and lifespan of the doors and windows.

[0003] Traditional window and door sealing strip installation relies heavily on manual labor using simple tools. This is not only labor-intensive but also makes it difficult to ensure the uniformity and fit of the strips. During manual operation, the pushing force and angle of the strips are entirely controlled by experience, easily leading to problems such as strip misalignment, wrinkles, and omissions. This results in decreased window and door sealing performance and a high rework rate. With the construction industry's increasing demands for window and door quality and the advancement of automated production, traditional manual installation methods can no longer meet the needs of large-scale, high-precision production.

[0004] To automate the installation of door and window sealing strips, some simple installation equipment has gradually emerged on the market. However, the installation components of existing equipment have obvious limitations in structural design. The pushing mechanism of some equipment adopts a rigid connection and lacks buffer adjustment capability. During the pushing process, the sealing strip is prone to deformation due to excessive force or insecure installation due to insufficient force. This causes the sealing strip to easily deviate during the pushing process and cannot be accurately aligned with the installation groove of the door and window. Based on this, a door and window sealing strip installation equipment is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a door and window sealing strip installation device, which solves the problem that some devices use rigid connections for their pushing mechanisms, lacking buffer adjustment capabilities. During the pushing process, the sealing strip is easily deformed due to excessive force, or the sealing strip is not securely installed due to insufficient force, resulting in the sealing strip easily shifting during the pushing process and failing to accurately align with the door and window mounting groove.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a door and window sealing strip installation device, including a device body, the device body being provided with a connecting mechanism, the connecting mechanism including a connecting component disposed at the bottom of the device body, an installation component disposed on the left side of the device body, and a receiving component disposed on the right side of the device body;

An L-shaped frame is fixedly connected to the right side of the top of the device body. A sensor is fixedly installed on the top of the inner wall of the L-shaped frame.

[0010] A further improvement is that the pressure-pressing frame is equidistantly arranged inside the push plate; because the pressure-pressing frame is equidistantly arranged inside the push plate, multiple adhesive strips can be installed simultaneously, improving installation efficiency; during the movement of the pressure-pressing frame, the slide block on the top of the connecting plate fixedly connected to its outer inner wall will slide along the slide rod; the connecting spring one sleeved on the outer wall of the middle section of the slide rod and the connecting spring two sleeved on the outer wall of the outer section play a buffering and shock-absorbing role, which can reduce the impact force generated during the pressure-pressing process and protect the equipment and adhesive strips from damage.

[0011] A further improvement is that the supporting legs are fixedly installed at the bottom of the device body, and the supporting legs are symmetrically arranged on both sides of the bottom of the device body; the connecting assembly includes supporting legs and a supporting base plate. The supporting legs are fixedly installed at the bottom of the device body and symmetrically arranged on both sides of the bottom of the device body. The supporting base plate fixedly connected to the bottom of the supporting legs is in contact with the ground, which stably supports the equipment in the working position and ensures that the equipment will not shake or shift during operation, providing a stable foundation for the installation of the adhesive strip.

[0012] A further improvement is that the top middle section of the receiving frame has a receiving groove, the bottom of the limiting plate is slidably connected to the bottom of the inner wall of the receiving groove, the L-shaped frame is fixedly installed at the connection between the receiving frame and the outer side of the device body, and a limiting hole is opened at the connection between the L-shaped frame and the receiving frame for the sensor to monitor the distance of the limiting plate.

[0013] A further improvement is that the connecting plate is fixedly connected to the top of the support plate, and the bottom of the L-shaped slide block is fixedly connected to the top of the support plate; the L-shaped slide block, which is slidably connected to the outer wall of the outer section of the slide rod, cooperates with the support plate to provide stable support for the movement of the pressure frame; the fixed slide block, which is fixedly connected to the bottom of the support plate, slides on the fixed slide rail, further ensuring the smoothness and accuracy of the movement of the pressure frame.

[0014] By employing the above technical solution, this utility model provides a door and window sealing strip installation device, which has at least the following beneficial effects:

[0015] 1. The cylinder in the installation assembly of this utility model drives the push plate and the pressure frame to move through the telescopic push rod. With the sliding guide of the fixed slide rail and the fixed slide seat, it can ensure the accurate pushing direction of the rubber strip and effectively avoid the problems of rubber strip deviation and wrinkling that are easy to occur in manual installation or traditional equipment. The connecting spring one and connecting spring two on the slide rod can buffer the impact force during the pushing process, which not only protects the rubber strip from damage, but also ensures the tight fit between the rubber strip and the door and window mounting groove, significantly improving the sealing performance.

[0016] 2. The equidistant design of the pressure-pressing frame in this utility model enables the simultaneous installation of multiple sets of adhesive strips, significantly improving work efficiency. The sliding cooperation of the slide block, L-shaped slide block, and slide rod, combined with the adjustment capability of the fixed slide block on the fixed slide rail, allows the installation components to adapt to the installation needs of different specifications of adhesive strips and doors and windows, reducing equipment adjustment time when changing products. The entire pushing process is automatically completed by the mechanical structure, reducing manual labor intensity and ensuring stable and reliable operation, which helps to reduce the rework rate and improve overall production efficiency.
