Description

Technical Field

[0001] The utility model relates to the technical field of laminated glass processing, in particular to a pre-pressing device for laminated glass. Background Art

[0002] Laminated glass is a composite material obtained by special processing of glass or plexiglass and high-quality engineering plastics. It is usually a transparent material, usually including a polycarbonate fiber layer sandwiched between ordinary glass layers. During the production process of laminated glass, a PVB film is sandwiched between every two pieces of glass. After the glass and the film are bonded, pressure is required to expel the air bubbles between the glasses, so that the two pieces of glass are preliminarily bonded together.

[0003] The existing laminated glass processing technology often adopts a laminated glass pre-pressing device disclosed in the patent with the publication number of CN220163417U. By placing the laminated glass on the sliding seat, the sliding seat is adjusted to the lower part of the pressure roller by the first driving cylinder, and the pre-pressing assembly is driven by the second driving cylinder to move downward, and the pressure roller is abutted against the upper surface of the laminated glass for pre-pressing. However, when this device is performing the pre-pressing work, the laminated glass is directly placed on the sliding seat. When the pressure roller rolls on the upper surface of the laminated glass, it will drive the laminated glass to shift in position, so that all the air bubbles in the laminated glass cannot be squeezed out, seriously affecting the quality of pre-pressing. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of the deflection of the position of laminated glass in the prior art, and to propose a pre-pressing device for laminated glass.

[0007] A support plate is welded on the partition plate, a second driving motor is fixedly installed on the support plate, and a pre-pressing mechanism for pre-pressing the laminated glass and driven by the second driving motor is arranged on the partition plate.

[0008] Preferably, the two groups of collection frames are equidistantly distributed at both ends of the center line of the main body.

[0009] Preferably, the fixing mechanism includes a double-headed lead screw installed on the output end of the first driving motor in a matching manner. Two nuts connected to the double-headed lead screw in a matching manner are slidably installed in the main body. A bearing bracket is fixedly installed on the two nuts. A sliding rod is slidably installed on the bearing bracket. A clamping plate fixedly connected to the sliding rod is slidably installed on the bearing bracket. A strong spring is connected between the clamping plate and the bearing bracket.

[0010] Preferably, serrations for increasing friction are provided on the opposite surfaces of the two clamping plates. The bearing bracket is in an L-shaped structure.

[0011] Preferably, the pre-pressing mechanism includes a turntable installed on the output end of the second driving motor in a matching manner. A pin is welded on the turntable. A driving rod is installed on the support plate by a pin shaft. A guiding groove slidably connected to the pin is provided on the driving rod. A driven rack meshed with the bottom end of the driving rod is slidably installed on the partition board.

[0012] A telescopic rod is fixedly installed at the bottom end of the driven rack. A support frame is fixedly installed at the output end of the telescopic rod.

[0014] Compared with the prior art, the present utility model has the following advantages:

[0016] 2. When the turntable rotates in the present utility model, it will drive the driving rod to make a reciprocating swinging motion, thereby driving the pressure roller to reciprocally roll on the laminated glass through the driven rack, and completely squeezing the air bubbles out of the laminated glass.

When squeezing the bubbles in the laminated glass, part of the glue liquid in the laminated glass will be squeezed out, resulting in the glue liquid splashing everywhere on the device. In order to keep the workbench surface clean, collection frames 3 are provided at both ends of the laminated glass to collect the extruded glue liquid. The two groups of collection frames 3 are equidistantly distributed at both ends of the center line of the main body 1. A first driving motor 4 is fixedly installed on the main body 1, and a fixing mechanism for clamping the laminated glass and driven by the first driving motor 4 is arranged inside the main body 1;

[0025] The fixing mechanism includes a double-ended screw rod 7 which is matched with the output end of the first driving motor 4. The two ends of the double-ended screw rod 7 are diametrically opposite threads. Therefore, when rotating, it will drive the nut 8 connected with itself to make opposite movements, and control the two groups of clamping plates 11 to clamp or loosen the laminated glass. Two groups of nuts 8 matched with the double-ended screw rod 7 are slidably installed in the main body 1. The two groups of nuts 8 are fixedly installed with a support frame 9. The support frame 9 is an L-shaped structure. The support frame 9 provides a stable placement platform for the laminated glass, which is convenient for The device fixes the laminated glass, a slide rod 10 is slidably installed on the support frame 9, a clamping plate 11 fixedly connected to the slide rod 10 is slidably installed on the support frame 9, and saw teeth for increasing friction are provided on the opposite surfaces of the two sets of clamping plates 11. At the same time, the contact surface between the clamping plate 11 and the laminated glass is made of rubber material, which is soft and can effectively protect the laminated glass, and the saw teeth can increase the friction between the two, so that the fixation of the laminated glass is more stable, and a strong spring 12 is connected between the clamping plate 11 and the support frame 9.

[0026] The pre-pressing mechanism includes a turntable 13 matched with the output end of the second driving motor 6, a latch 14 is welded on the turntable 13, and the latch 14 is eccentrically welded on the turntable 13. A driving rod 15 is installed on the pin shaft of the support plate 5. The bottom end of the driving rod 15 is a fan-shaped gear structure. A guide groove 16 is provided on the driving rod 15 to be slidably connected to the latch 14. A driven rack 17 meshingly connected to the bottom end of the driving rod 15 is slidably installed on the partition 2. When the latch 14 rotates to the left side of the support plate 5, the driven rack 17 will slide to the right side of the partition 2;

When the pressure roller 22 contacts the laminated glass, the compression spring 21 will shrink to prevent the pressure roller 22 from applying too much pressure on the laminated glass and causing damage to the laminated glass.

[0028] It should be noted that the specific models and specifications of the first drive motor 4 and the second drive motor 6 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.
