Description

Technical Field

[0001] The utility model relates to the field of internal gluing equipment, in particular to an internal gluing head for an extremely narrow door and an internal gluing device. Background Art

[0002] In recent years, extremely narrow doors have attracted people's attention and love. Compared with traditional doors and windows, extremely narrow doors can improve space utilization, and the overall design is more simple, showing a slender and light feeling. The design characteristics of extremely narrow doors enable them to be used in different scenarios, especially in small-sized houses, especially in bedrooms, study rooms, bathrooms and other spaces, which can effectively save space. At the same time, extremely narrow doors are generally used in sliding door designs, and it is precisely because of this sliding door design that more space can be saved.

[0003] Ultra-narrow sliding doors are mainly glass doors composed of an extremely narrow frame and central glass. The central glass is usually fixed in the extremely narrow frame by gluing. At present, doors and windows are mainly fixed by internal gluing and external gluing. Compared with external gluing, internal gluing has more advantages in terms of aesthetics and long-term stability. For doors and windows with extremely narrow frames, internal gluing can not only improve the appearance, but also effectively avoid problems such as fogging of insulating glass, which is a more recommended choice.

[0004] At present, the internal glue-spraying device of the extremely narrow frame can inject the sealant into the glass installation groove, but there are still some areas to be improved in practical applications. For example, the extremely narrow frame is sometimes designed with functional components such as locking. When these functional components are installed on the extremely narrow frame, they will protrude from the glass installation groove, which leads to the need to avoid the internal glue-spraying. The existing technology generally requires the use of manual or electric methods to raise the entire glue-spraying machine head to avoid it. Manual operation is not only time-consuming and labor-intensive, but also inefficient. Although the electric method realizes automation, it requires the entire glue-spraying head to be raised and lowered, which is relatively bulky and inflexible. For example, a glue-spraying machine for door frame processing disclosed in a Chinese patent (authorization announcement number: CN220678412U). Therefore, it is necessary to optimize and improve the existing internal glue-spraying equipment in order to make it more practical. Utility Model Content

DETAILED DESCRIPTION

[0039] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0040] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0041] It should be noted that the following “X-axis” is defined as the left-right direction in the drawings, the “Y” axis is defined as the front-back direction in the drawings, and the “Z” axis is defined as the up-down direction in the drawings.

[0042] like Figure 1-3 As shown, the present application is an internal gluing head and an internal gluing device for extremely narrow doors, which are used for gluing the inside of extremely narrow door frames such as sliding doors in small spaces such as kitchens and washrooms.

[0043] Among them, the glue head inside the extremely narrow door includes a movable carrier 101, a first guide rail 102 is provided on the movable carrier 101 along the Z-axis direction, a first sliding seat 105 is slidably provided on the first guide rail 102, and the lifting and lowering of the first sliding seat 105 is realized by a power unit. The specific power unit is set on the movable carrier 101, and it is connected to the first sliding seat 105 to drive its lifting and lowering.

[0044] A second sliding seat 107 is also provided on the first sliding seat 105. The second sliding seat 107 is slidably arranged along the Z-axis direction. Specifically, a slide groove is provided on the first sliding seat 105. The second sliding seat 107 has a slide rail. The slide rail is slidably arranged in the slide groove. The fixing and sliding of the second sliding seat 107 at a certain position on the slide groove are realized by the lifting drive member 106. Specifically, the lifting drive member 106 is provided on the first sliding seat 105 and connected to the second sliding seat 107. The lifting drive member 106 drives the second sliding seat 107 to rise and fall.

[0045] A pneumatic dispensing valve 108 is fixed on the second sliding seat 107, and the pneumatic dispensing valve 108 can inject glue into the groove of the extremely narrow door frame profile 7. The lifting drive member 106 drives the pneumatic dispensing valve 108 to rise and fall in the process of driving the second sliding seat 107 to rise and fall.

[0046] During normal gluing, the pneumatic dispensing valve 108 stops at a certain height position and remains unchanged. The entire internal gluing head 1 only moves in the X-axis direction to inject the glue into the groove of the slender and extremely narrow door frame profile 7. When there is a lock component in the groove of the extremely narrow door frame profile 7, the needle nozzle of the pneumatic dispensing valve 108 mainly skips the lock component and continues to glue. At this time, the lifting drive 106 drives the pneumatic dispensing valve 108 to rise and then descend to achieve.

[0047] It should be noted that the action of the lifting drive member 106 is controlled by an external controller, and the specific position of the lock component is determined by the distance between the lock component and the end of the extremely narrow door frame profile 7. According to the relationship between the walking speed, time and distance of the internal glue head 1, it is written into the programming program, and the action of the lifting drive member 106 is automatically controlled through programming.

[0048] In addition, the above-mentioned pneumatic dispensing valve 108 is purchased directly from the market, and its structure is the existing technology, so the applicant does not describe its structure in detail here.

[0049] Furthermore, the structure of the power unit includes a screw 104, both ends of which are rotatably arranged on the movable carrier 101 through bearings, and a hand wheel 103 is connected to the top of the screw 104, and the screw 104 is rotated by manually rotating the hand wheel 103. The reason why the hand wheel 103 is manually rotated is that the height adjustment here is not frequent, and the same batch of profiles with the same height only need to be adjusted once. The height adjustment here is to determine the height of the pneumatic dispensing valve 108 according to the height of the profile. Therefore, if the profiles are of the same height, it only needs to be adjusted once, and there is no need to adjust frequently. Manual adjustment is more suitable for such occasions where adjustment is not frequent, and it will also simplify the structural setting.

[0050] Furthermore, in order to improve the stability of the lifting of the first sliding seat 105, a guide hole is provided on the first sliding seat, and a guide rod 109 is provided on the movable carrier 101 along the Z-axis direction, and the guide rod 109 is arranged through the guide hole.

[0055] In addition, it also includes a glue supply mechanism 6 and a profile clamping component 5. The glue supply mechanism 6 is arranged on the movable carrier 101 and connected to the pneumatic glue dispensing valve 108 to provide glue to the pneumatic glue dispensing valve 108. The profile clamping component 5 is arranged on the frame 2 and is located at the front side of the inner glue head 1, and can clamp and fix the extremely narrow door frame profile 7.

[0056] Furthermore, the structure of the above-mentioned driving component 4 specifically includes a rack 403, a motor 401 and a gear 402.
