Description

Technical Field

[0001] This invention belongs to the field of door and window processing technology, and particularly relates to a door and window packaging machine and its working method. Background Technology

[0002] The final packaging process in aluminum alloy door and window manufacturing enterprises still relies on manual operation, typically requiring 2-3 workers to continuously wrap the packaging film. This process involves frequent handling of finished doors and windows, resulting in high labor intensity and costs, as well as inconsistent packaging quality due to variations in manual operation. This fails to meet the efficiency and standardization requirements of large-scale production, making the industry's need for automated packaging equipment extremely urgent. However, most existing door and window packaging equipment on the market uses full-width packaging technology. Although it can achieve basic automation, it suffers from redundant coverage of the packaging film, low material utilization, and an inability to mimic manual packaging by wrapping the film according to the structure and corner shape of the door and window profiles. This leads to a significant increase in packaging film consumption, directly driving up manufacturing costs for enterprises, which contradicts the current trend of cost reduction and efficiency improvement in the manufacturing industry. Among these, screens, as a core component of doors and windows, need to be wrapped and packaged together with the main body of the doors and windows to ensure transportation safety. However, the wrapping heads of existing packaging machines are limited by fixed stroke and specification adaptation range, which cannot meet the packaging needs of screens. On the one hand, there is no uniform standard for the installation position of screens on aluminum alloy doors and windows, resulting in uncertainties such as left-right and up-down offsets. On the other hand, the screen sizes corresponding to different models of doors and windows vary significantly, making it difficult for traditional wrapping equipment to accurately cover the packaging area. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a door and window packaging machine and its operating method. The machine uses a wrapping film head on a gantry frame to wrap the edges of doors and windows, and a reversing mechanism to wrap the screens on the doors and windows. By using a first reversing clamping component and a second reversing clamping component, the machine achieves the purpose of mimicking two workers performing the reversing wrapping, thus solving the problem of precise wrapping of screens of different sizes.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] Example 1: like Figure 1 As shown, this embodiment provides a door and window packaging machine, including a bed 4, a gantry frame 2, a conveying mechanism 3 and a reversing mechanism 5 disposed on the bed 4, and a wrapping film head 1 disposed on the gantry frame 2; the gantry frame 2 and the conveying mechanism 3 are respectively disposed at both ends of the bed 4 to avoid mutual interference.

[0020] The stretch film head 1, driven by the gantry frame 2, can reach the door and window packaging area to wrap the stretch film around the door and window frame or other locations. Figure 2As shown, the wrapping head 1 includes a wrapping head connecting seat 101 for connecting with the gantry 2, a wrapping frame 102 disposed on the wrapping head connecting seat 101, a wrapping assembly 103 and a first telescopic member 104 disposed on the wrapping frame 102, a second telescopic member 105 and a third telescopic member 107 disposed on the first telescopic member 104, a hook film plate disposed on the second telescopic member 105, and a film cutting assembly disposed on the third telescopic member 107.

[0021] The winding frame 102 is an arc-shaped frame with a notch, and the door and window frame enters the winding frame 102 through the notch during winding; the extension and retraction directions of the second telescopic member 105 and the first telescopic member 104 are perpendicular, and the extension and retraction directions of the third telescopic member 107 are parallel to the extension and retraction directions of the first telescopic member 104. The telescopic members in this invention can be electric telescopic rods, hydraulic telescopic rods, pneumatic telescopic rods, linear motors, screw and nut mechanisms, or other telescopic members.

[0022] like Figure 2 and Figure 3 As shown, the winding assembly 103 is used to wind the stretch film on the film holder 1037 onto the door and window frame; the winding assembly 103 includes a first drive motor 1301 disposed on the winding frame 102, a drive pulley 1032 disposed on the first drive motor 1301, at least one driven pulley 1033 disposed on the winding frame 102, a gear 1034 connected to the driven pulley 1033, a plurality of guide wheels 1036 disposed on the winding frame 102, an arc-shaped rack 1035 rotatably disposed on the winding frame 102, and a film holder 1037 disposed on the arc-shaped rack 1035; the gear 1034 meshes with the arc-shaped rack 1035.

[0023] A conveyor belt is provided between the driving pulley 1032 and the driven pulley 1033; the guide wheels 1036 are arranged in an arc shape, and the arc-shaped rack 1035 is located between the intersecting guide wheels 1036. The guide wheel 1036 located outside the arc-shaped rack 1035 can be a small gear that meshes with the arc-shaped rack 1035, and the guide wheel 1036 located outside the arc-shaped rack 1035 can be a rolling wheel that contacts the arc-shaped rack 1035. like Figure 4 As shown, the film cutting assembly 106 includes a first electrode plate 1061 and a second electrode plate 1062, and a heating wire 1063 disposed on the first electrode plate 1061 and the second electrode plate 1062; the first electrode plate 1061 and the second electrode plate 1062 can be respectively connected to the two poles of a power supply.

[0024] During operation, the drive arc-shaped rack 1035 moves, causing the film holder 1037 to rotate and wrap the stretch film on the door or window. When the wrapping is complete, the first telescopic member 104 controls the entire film cutting assembly 6 to descend to a suitable position. Then, the second telescopic member 105 controls the hook plate 108 (which has hooks or grooves that can hook the stretch film) to extend and hook the stretch film. The second telescopic member 105 controls the hook plate 108 to retract, pulling the stretch film to a position below the film assembly 106. Then, the third telescopic member 107 controls the film cutting assembly 106 to descend and disconnect the stretch film, completing the stretch film cutting.

[0025] When the second telescopic member 105 controls the hook plate 108 to extend, the hook plate 108 is provided with hooks or grooves that correspond to the film frame in the vertical direction. At this time, when the arc-shaped rack 1035 is rotated, the film on the film frame will be hooked onto the hooks or grooves. Then the second telescopic member 105 controls the hook plate 108 to retract, thus realizing the hooking action.

[0026] like Figure 1 and Figure 5 As shown, the gantry frame 2 is movably mounted on the bed 4 via a second drive motor 201 and a linear drive device, and the entire frame can move relative to the bed 4. The gantry frame 2 includes a vertical beam 202, a horizontal beam 203 connected to the vertical beam 202, a movable frame 205 mounted on the horizontal beam 203 via a third drive motor 204 and a linear drive device, and a fifth drive motor 207 mounted on the movable frame 205 via a fourth drive motor 206 and a linear drive device. The winding head connecting seat 101 of the winding head 1 is connected to the output shaft of the fifth drive motor 207, enabling rotational drive.

[0027] During operation, when it is necessary to adjust the angle at which the wrapping head 1 rotates to wrap the door or window, the fifth drive motor 207 rotates to change the forward angle of the wrapping head 1. The third drive motor 204 and the linear drive device control the movement of the wrapping head 1 in the x-axis direction, that is, its horizontal movement on the crossbeam 203. The fourth drive motor 206 and the linear drive device control the lifting and lowering movement of the entire wrapping head 1, ensuring the accuracy of the working position of the wrapping head 1. The second drive motor 201 and the linear drive device maintain the accurate movement position of the entire gantry frame 2 as it moves on the bed.

[0028] like Figure 6As shown, the conveying mechanism 3 includes a fixed conveying component 301 mounted on the bed 4, and a movable conveying component 302 mounted on the bed 4 that is movably mounted on the bed 4 via a distance adjustment drive component 303; the fixed conveying component 301 and the movable conveying component 302 are respectively provided with a first conveyor belt component 304 and a second conveyor belt component 305 for conveying doors and windows; the fixed conveying component 301 and the movable conveying component 302 are also respectively provided with a lifting component 306 for clamping and lifting doors and windows.

[0029] The mobile conveying component 302 can be a telescopic component, a linear motor, or other driving equipment; the first conveyor belt component 304 and the second conveyor belt component 305 can include components such as a motor, pulleys, and a conveyor belt, which can be implemented using conventional components and will not be described in detail here. Depending on the size of the doors and windows, the movement of the mobile conveying component 302 can be adjusted by the distance adjustment drive component 303, so that the distance between the fixed conveying component 301 and the mobile conveying component 302 adapts to the size of the doors and windows, achieving stable conveying of the doors and windows.

[0030] like Figure 7 As shown, the lifting assembly 306 includes a horizontal adjustment assembly 3061 slidably disposed on the fixed conveying assembly 301 or the mobile conveying assembly 302, a lifting drive assembly 3062 disposed on the horizontal adjustment assembly 3061, a clamping drive assembly 3063 disposed on the lifting drive assembly 3062, and a clamping plate 3064 disposed at the output end of the clamping drive assembly 3063.

[0031] The horizontal adjustment component 3061 can be mounted on the fixed conveying component 301 or the mobile conveying component 302 via a slide rail, and its movement and adjustment on the slide rail are achieved by a motor and drive wheels. The lifting drive component 3062 can be a cylinder, a hydraulic telescopic rod, or other lifting device, used to drive the lifting of the clamping drive component 3063 and the clamping plate 3064. The clamping drive component 3063 can be a cylinder, a hydraulic telescopic rod, or other lifting device, used to drive the clamping plate 3064 to clamp the sides of the door or window, thereby fixing the door or window.

[0032] During operation, the distance adjustment drive assembly 303 controls the distance between the fixed conveyor assembly 301 and the moving conveyor assembly 302 to ensure that the doors and windows can enter the conveyor 3. The first conveyor belt assembly 304 and the second conveyor belt assembly 305 transport the doors and windows into the working position within the conveyor belt; then, the horizontal adjustment assembly 3061 moves the lifting assembly 306 in the horizontal direction, controlling the lifting assembly 306 to reach the designated position. The clamping drive assembly 3063 controls the clamping plate 3064 to clamp the doors and windows. Finally, the lifting drive assembly 3062 lifts the entire door and window to the working position.

[0033] like Figure 8 As shown, the reversing mechanism 5 includes a reversing gantry 501 mounted on the bed 4 via a reversing drive assembly 502, a first reversing rotation drive assembly 505 movably mounted on the upper part of the reversing gantry 501 via a first reversing horizontal drive assembly 503, a first reversing clamping assembly 504 mounted on the first rotation drive assembly 505, a vertical moving support plate 509 mounted on the lower part of the reversing gantry 501 via a reversing vertical drive assembly 506, and a second reversing clamping assembly 508 mounted on the vertical moving support plate 509 via a second reversing rotation drive assembly 507.

[0034] The reversing drive assembly 502 may include a rail connected to the bed 4, and a linear motor, telescopic component, or other drive device capable of driving the reversing gantry 501 to move on the bed 4. The first horizontal drive assembly 503 may be implemented using a linear motor or other drive device. The reversing vertical drive assembly 506 may be implemented using a telescopic component or other device. Both the first rotation drive assembly 505 and the penultimate rotation drive assembly 507 may be implemented using a rotation motor or other device.

[0035] like Figure 9 As shown, the first hand-reversing clamping assembly includes a second horizontal hand-reversing drive assembly 5041 disposed on the first rotation drive assembly 505, a hand-reversing conveying drive assembly 5042 disposed on the second horizontal hand-reversing drive assembly 5041, and a first gripper 5043 disposed on the hand-reversing conveying drive assembly 5042.

[0036] The second hand-reversing clamping assembly 508 includes a third horizontal drive assembly 5081 for reversing the hand-re ...

[0037] Both the second horizontal drive assembly 5041 and the third horizontal drive assembly 5081 can be implemented using linear motors or similar methods. The conveying drive assembly 5042 can be implemented using telescopic components, linear motors, or other drive devices. Both the first gripper 5043 and the second gripper 5082 include drive devices and two clamping plates for holding the film holder 1037.

[0038] During operation, the reversing drive assembly 502 moves the reversing gantry 501 to the designated position; the vertical moving support plate 509 is lifted to the working position by the action of the reversing vertical drive assembly 506; after the reversing first rotation drive assembly 505, the reversing second rotation drive assembly 507, the reversing second horizontal drive assembly 5041, and the reversing third horizontal drive assembly 5081 move the first gripper 5043 and the second gripper 5082 to the working position; the reversing conveying drive assembly 5042 automatically delivers the first gripper 5043 with the film holder to the second gripper 5082, and the second gripper 5082 clamps the film holder and moves it through the reversing... The second rotation drive assembly 507 and the third horizontal drive assembly 5081 move the second gripper 5082 with the film frame to the other side of the screen. Similarly, the first gripper 5043 moves to the other side of the screen under the action of the first rotation drive assembly 505 and the second horizontal drive assembly 5041. The transport drive assembly 5042 sends the first gripper 5043 to the second gripper 5082 again. The second gripper 5082 releases the film frame from the first gripper 5043, realizing the second hand-over. The above actions are repeated to realize the overall hand-over action in the winding process, realizing the film wrapping operation of the screen.

[0039] Example 2: This embodiment provides a working method for a door and window packaging machine, which uses the door and window packaging machine as described in Embodiment 1. The method includes wrapping the frame of the door and window with a wrapping film head 1 on the gantry frame 2; wrapping the screen on the door and window with a reversing mechanism 5, wherein the first reversing clamping component 504 and the second reversing clamping component 508 alternately reverse the film frame, simulating two workers performing reversing wrapping.

Various modifications and variations can be made to this practice by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this practice should be included within the protection scope of this practice.
