Description

Technical Field

[0001] The utility model belongs to the technical field of elevator door panel production, and particularly relates to a self-weight type pressing equipment for elevator door panels after gluing. Background Art

[0002] During the production of elevator doors, glue needs to be applied to the elevator door panels, and then the glued elevator door panels are attached to the front and back surfaces of the door frames to assemble a complete elevator door. In order to make the elevator door panels stick more firmly to the door frames, the existing method is to manually press the elevator door panels after they are attached to the door frames to make them fit tightly between the elevator door panels and the door frames. However, this method cannot ensure that every position of the elevator door panels can be pressed, resulting in some positions of the elevator door panels still not fitting firmly. Moreover, the pressure applied manually each time is different, which easily leads to different bonding degrees at different positions of the elevator door panels, causing some positions of the elevator door panels to be bonded more firmly and some positions to have insufficient bonding degree and be prone to loosening, and unable to ensure the overall processing quality of the elevator doors. Content of the Utility Model

[0003] (1) Purpose of the Utility Model

[0004] In order to overcome the above deficiencies, the purpose of the utility model is to provide a self-weight type pressing equipment for elevator door panels after gluing, so as to solve the technical problem that the existing elevator door processing has poor sticking effect when attaching elevator door panels and cannot ensure the overall processing quality of elevator doors.

[0005] (2) Technical Solution

[0006] To achieve the above purpose, the technical solution provided by this application is as follows:

[0007] A self-weight type pressing equipment for elevator door panels after gluing, comprising: a frame, a plurality of driving rollers arranged side by side and rotatably on the frame for transporting elevator door panels, and a pressing roller extending horizontally and swingably above the driving rollers, which can swing downward to squeeze the elevator door panels when the elevator door with the elevator door panel attached passes below it.

[0008] In this application, by setting a plurality of driving rollers and a swingable pressing roller, when processing elevator doors, first attach the glued elevator door panels to the door frames, then place the elevator doors on the driving rollers and transport them forward. Before the elevator doors are transported to the pressing roller, the pressing roller swings upward first to avoid blocking the forward movement of the elevator doors. When the elevator doors move to directly below it, the pressing roller swings downward and squeezes the door panels by its own gravity. As the elevator door panels move forward, the pressing roller can apply pressure to the elevator door panels evenly in all directions, ensuring that the entire elevator door panels can be firmly attached to the door frames and ensuring the overall processing quality of the elevator doors.

[0009] In some embodiments, it further includes: a pressure roller mounting bracket hinged to the frame and fixedly connected to the pressure roller at the first end, and a driving device correspondingly arranged at the second end of the pressure roller mounting bracket and capable of moving up and down to drive the pressure roller mounting bracket and the pressure roller to swing.

[0010] By arranging the driving device, when the elevator door is about to move below the pressure roller, the first end of the pressure roller mounting bracket and the pressure roller can be driven to swing upward. When the elevator door moves directly below the pressure roller, the second end of the pressure roller mounting bracket is released, so that the pressure roller can fall onto the elevator door panel of the elevator door to squeeze the elevator door panel, which can avoid the forward movement of the elevator door being blocked due to the too low initial position of the pressure roller.

[0011] In some embodiments, it further includes: an adjusting rod correspondingly arranged at the second end of the pressure roller mounting bracket and threadedly connected to the frame. The adjusting rod extends vertically, and its lower end can move to a predetermined position to abut against the second end of the pressure roller mounting bracket to limit the downward swing amplitude of the first end of the pressure roller mounting bracket.

[0012] In some embodiments, a buffer layer is annularly arranged on the surface of the pressure roller;

[0013] By arranging the buffer layer, it can be avoided that the pressure roller directly contacts the elevator door panel rigidly, resulting in the elevator door panel being scratched or dented due to extrusion. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0020] A self-weight pressing device for elevator door panels after gluing provided by the utility model includes: a frame 1, a plurality of driving rollers 2 arranged side by side and rotatably on the frame 1 for transporting elevator door panels, and a pressing roller 3 extending horizontally and swingably above the driving rollers 2, which can swing downward to squeeze the elevator door panel when the elevator door attached with the elevator door panel passes below it.

[0021] Specifically, a driving chain is connected between the plurality of driving rollers 2, and the driving chain is connected to a motor. The rotation of the motor drives the plurality of driving rollers 2 to rotate synchronously to convey the elevator door forward.

[0022] Specifically, a pressing roller mounting frame 4 is provided in this application. The pressing roller mounting frame 4 is hinged to the frame 1. The pressing roller 3 is arranged at the first end of the pressing roller mounting frame 4. A driving device 5 is arranged at the position corresponding to the second end of the pressing roller mounting frame 4. The driving device 5 can be a cylinder. The cylinder is arranged vertically. Before the elevator door is transmitted to the pressing roller 3, the driving shaft of the cylinder extends downward, driving the second end of the pressing roller mounting frame 4 to swing downward, so that the first end of the pressing roller mounting frame 4 and the pressing roller 3 swing upward synchronously to supply the elevator door to move forward. When the elevator door moves to directly below the pressing roller 3, the driving shaft of the cylinder moves upward to reset, the second end of the pressing roller mounting frame 4 swings upward, and the first end of the pressing roller mounting frame 4 and the pressing roller 3 swing downward synchronously to abut against the elevator door panel. During the forward movement of the elevator door, the pressing roller 3 rotates continuously to apply pressure to the elevator door panel.

[0023] Specifically, an adjusting rod 7 with a threaded structure is also provided in this application. The adjusting rod 7 is threadedly connected to the frame 1. A handwheel 6 is arranged at the upper end of the adjusting rod 7. The lower end of the adjusting rod 7 abuts against the second end of the pressing roller mounting frame 4. When the first end of the pressing roller mounting frame 4 swings downward and the second end swings upward to abut against the lower end of the adjusting rod 7, the first end of the pressing roller mounting frame 4 stops swinging downward. The adjusting rod 7 can limit the swinging amplitude of the first end of the pressing roller mounting frame 4. Specifically, by holding the handwheel 6 and rotating the adjusting rod 7, the height of the lower end of the adjusting rod 7 can be adjusted, so as to adjust the swinging amplitude of the first end of the pressing roller mounting frame 4.

[0024] Specifically, a plurality of pressing rollers 3 can be arranged at intervals.

[0025] Preferably, a buffer layer is annularly arranged on the surface of the pressing roller 3. The buffer layer can be made of a soft material such as silica gel or foam.
