Description

Technical Field

[0001] This utility model relates to the field of adhesive coating machine technology, and in particular to a butyl sealant coating machine for insulating glass. Background Technology

[0002] Insulating glass, as a key material for energy conservation in modern buildings, is widely used in curtain walls, doors and windows due to its excellent heat insulation, sound insulation performance and structural stability. Its core structure consists of two (or three) panes of glass and an aluminum alloy spacer frame containing a desiccant, bonded together with a high-strength sealing material. Butyl rubber, as the first sealing layer, directly undertakes the core function of blocking water vapor penetration and maintaining the dryness of the cavity. The uniformity and continuity of its coating have a decisive impact on the lifespan and performance of the insulating glass.

[0003] In the existing technology, the traditional glue application method is to arrange rectangular aluminum strips vertically, so that one side of the aluminum strip is pressed on the belt conveyor. The belt conveyor causes the nozzle to move relative to one side of the aluminum strip, thereby achieving the glue application on one side of the aluminum strip. Then, the operator adjusts the rotation angle of the aluminum strip to perform the next round of glue application. The entire glue application process needs to be repeated four times, which makes the operation quite cumbersome. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a butyl sealant coating machine for insulating glass.

[0005] The technical solution of this utility model is a butyl sealant coating machine for insulating glass, which includes a first frame, a rectangular frame, a sealant outlet pipe, a rotating device, and a feeding mechanism.

[0006] A rectangular frame is positioned above the first frame and is fixedly connected to it. The rotating device includes a servo motor and an elastic telescopic mechanism. A cross is connected to the inner side of the rectangular frame, and the servo motor is mounted on the cross. The elastic telescopic mechanism includes a sleeve, a movable rod, and an elastic connecting assembly. A hollow rotating shaft is mounted on the end of the sleeve, and the hollow rotating shaft is rotatably mounted on the cross and connected to the output shaft of the servo motor. The end of the movable rod is slidably located inside the sleeve, and the movable rod and the sleeve are elastically connected by the elastic connecting assembly. A movable shaft is rotatably mounted on the movable rod, and the movable shaft contacts the outer wall of the rectangular frame. A glue dispensing tube is installed at the end of the movable rod, and a glue spray nozzle is mounted at the bottom of the glue dispensing tube. A flexible hose is connected between the upper end of the glue dispensing tube and the hollow rotating shaft. A feeding mechanism is used to deliver glue into the hollow rotating shaft.

[0007] Preferably, limit blocks are provided around the upper surface of the first frame.

[0008] Preferably, the feeding mechanism includes a glue tank, a rotary joint, a valve, and a connecting pipe. A second frame is provided on the first frame, the glue tank is located on the second frame, the rotary joint is installed on the hollow rotating shaft, the rotary joint and the glue tank are connected by a connecting pipe, and the valve is installed on the connecting pipe.

[0009] Preferably, a piston plate is installed inside the glue tank, and an electric push rod for driving the piston plate to move is installed on the glue tank.

[0010] Preferably, the elastic connection assembly includes a spring, a guide rod, and a connecting slider. The inner end of the movable rod is connected to the connecting slider, and a sliding hole is provided on the sleeve for the connecting slider to slide. Both ends of the guide rod are connected to the outer wall of the sleeve. The connecting slider is slidably mounted on the guide rod, and the spring is sleeved on the guide rod.

[0011] Preferably, the hose is a flexible metal hose, the length of which is greater than the maximum extension length of the elastic telescopic mechanism.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects: In this technical solution, the rectangular frame and elastic telescopic mechanism can limit the movement of the movable shaft, thereby forcibly changing the circumferential rotation of the glue dispensing tube, so that the glue dispensing tube can move along the circumference of the aluminum strip, and the glue sprayed by the glue nozzle during the movement is applied to the aluminum strip, realizing automatic glue application. The glue application is completed in one go, without the need for manual flipping, thus improving the glue application efficiency. Attached Figure Description

[0018] Example 1

[0019] like Figures 1-5 As shown in the figure, the insulating glass butyl sealant coating machine proposed in this embodiment includes a first frame 1, a rectangular frame 4, a sealant outlet pipe 8, a rotating device, and a feeding mechanism.

[0020] The rectangular frame 4 is located above the first frame 1, and the rectangular frame 4 is fixedly connected to the first frame 1.

[0021] The rotating device includes a servo motor 16 and an elastic telescopic mechanism. A cross is connected to the inner side of the rectangular frame 4. The servo motor 16 is mounted on the cross. The elastic telescopic mechanism includes a sleeve 6, a movable rod 7, and an elastic connecting assembly. A hollow rotating shaft 10 is installed at the end of the sleeve 6. The hollow rotating shaft 10 is rotatably mounted on the cross and connected to the output shaft of the servo motor 16. The end of the movable rod 7 is slidably located inside the sleeve 6. The movable rod 7 and the sleeve 6 are elastically connected by the elastic connecting assembly. A movable shaft 19 is rotatably mounted on the movable rod 7. The movable shaft 19 contacts the outer wall of the rectangular frame 4. A glue dispensing tube 8 is installed at the end of the movable rod 7. A glue spray nozzle 9 is installed at the bottom end of the glue dispensing tube 8. A flexible hose 11 is connected between the upper end of the glue dispensing tube 8 and the hollow rotating shaft 10. Its length is greater than the maximum telescopic length of the elastic telescopic mechanism.

[0022] The feeding mechanism is used to deliver glue into the hollow rotating shaft 10. The feeding mechanism includes a glue tank 3, a rotary joint 12, a valve 17, and a connecting pipe 18. A second frame 2 is provided on the first frame 1. The glue tank 3 is located on the second frame 2. The rotary joint 12 is installed on the hollow rotating shaft 10. The rotary joint 12 and the glue tank 3 are connected by the connecting pipe 18. The valve 17 is installed on the connecting pipe 18. A piston plate is installed inside the glue tank 3. An electric push rod 13 for driving the piston plate to move is installed on the glue tank 3.

[0023] In this technical solution, a PLC controller is used to control the equipment.

[0024] In this embodiment, the rectangular aluminum strip to be bonded to the insulating glass is placed on the first frame 1, and the servo motor 16 is started to drive the elastic telescopic mechanism to rotate around the hollow rotating shaft 10. The cooperation between the rectangular frame 4 and the elastic telescopic mechanism can limit the movement path of the movable shaft 19, and can forcibly change the circumferential rotation of the glue dispensing tube 8, so that the glue dispensing tube 8 can move along the circumference of the aluminum strip. The glue spraying nozzle 9 contacts the aluminum strip, and the glue sprayed during the movement is applied to the aluminum strip, realizing automatic glue application.

[0025] To further address the issue of poor glue flow, a piston plate with a clearance fit to the inner wall is installed inside the glue tank 3. A sealing adjustment is provided around the piston plate. An electric push rod 13 is added to push the piston plate to move vertically to assist glue dispensing. However, it is worth noting that air holes should be provided on the glue tank 3.

[0026] In summary, this technical solution achieves automatic glue application on the aluminum strip by driving the glue spray nozzle 9 to move along the circumference of the aluminum strip. The glue application is completed in one go without the need for manual flipping, thus improving the glue application efficiency.

[0027] Example 2

[0028] like Figure 1 As shown in the figure, the insulating glass butyl sealant coating machine proposed in this embodiment has a limitation block 5 around the upper surface of the first frame 1 in order to limit the aluminum strip. The limitation block 5 is used to limit the aluminum strip around the perimeter, thereby preventing the aluminum strip from deviating during the sealant application process.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
