Description

Technical Field

[0001] The invention relates to the field of glue spraying devices, in particular to a glue spraying device for processing modified PETG sheets. Background Art

[0002] Modified PETG sheet, also known as modified GPET sheet, is made of a non-crystalline PET resin modified by cyclohexanediol. At present, during the processing of modified PETG sheet, it is necessary to spray glue and then paste two sheets together. At this time, a glue spraying device is needed to spray glue on the sheet. However, the existing glue spraying device can only meet the glue spraying work of the sheet. After the sheet is sprayed with glue, it needs to be transferred to the composite device to bond the two sheets. The transfer process not only wastes time and affects efficiency, but also after the sheet is sent into the glue spraying device, the cylinder is pushed to reset and return without performing any work, resulting in waste of the return stroke of the pushing device. In order to solve the above-mentioned problems, we propose a glue spraying device for processing modified PETG sheet. Summary of the invention

[0003] The invention aims to provide a glue spraying device for processing modified PETG sheets, which has the advantages of being able to complete the glue spraying and compounding of the modified PETG sheets and avoiding the waste of return caused by empty return of a pushing device.

[0007] The above technical solution is adopted, and the pushing device is set to drive the two electric clamps to move;

[0008] The distance between sliding table 1 and sliding table 2 threadedly connected to the surface of the driving screw always remains unchanged. When sliding table 1 is located at the center of the glue spraying chamber, sliding table 2 will be away from the glue spraying chamber, and when sliding table 2 is located at the center of the glue spraying chamber, sliding table 1 will be away from the glue spraying chamber.

[0009] The present invention is further configured as follows: the linkage assembly includes a connecting plate 1, the bottom of the connecting plate 1 is fixedly connected to the sliding platform 1, and the bottom of the connecting plate 2 is fixedly connected to the sliding platform 2;

[0012] The above technical solution is adopted to drive the gear to rotate through the setting of the linkage component;

[0013] There are two gears, one on the left and one on the right. Figure 2 and Figure 4 When the left tooth plate 1 is pushed by the electric telescopic rod 1 and meshes with the left gear, the connecting plate 1 on the top of the sliding platform 1 will drive the two tooth plates 1 to move forward as the driving screw drives the connecting plate 1 on the top of the sliding platform 1 clockwise. At this time, the left tooth plate 1 will push the left gear to rotate clockwise until the adsorption component on the top of the electric telescopic rod 2 inside the gear is rotated to the center of the glue spraying chamber and corresponds to the sheet after glue spraying;

[0014] The right side toothed plate 1 is meshed with the right side gear, and the driving screw rotates clockwise to drive the sliding platform 1 to drive the connecting plate 1 and the toothed plate 1 to move.

[0018] The bottom of the fixed rod does not contact the processing table, and is partially supported by the processing table extended by the electric telescopic rod 2. When the electric telescopic rod 2 rotates, the fixed rod will rotate synchronously with the electric telescopic rod 2, and the support rod slides up and down inside the fixed rod.

[0068] Working principle:

[0069] When working, the two electric suction cups 82 are located in the glue spraying chamber 5 as shown in the figure;

[0070] First, the sheets to be bonded and to be compounded are placed in the two sheet placement grooves 11 respectively, and are butted against each other, and the three sides of the sheets are brought into contact with the wall of the processing table 1 through the wall of the processing table 1 and are leveled.

[0071] The sheet to be sprayed with glue is placed on the side of the electric clamp 9 which is not in the glue spraying chamber 5, and the sheet and the side of the electric clamp 9 close to the sheet are fitted together; then the electric clamp 9 is started, and its two clamps are moved together, and the sheet is calibrated to the center, and the two clamps are clamped after the two clamps are in contact with the sheet; the push motor 202 is started to drive the driving screw 203 to rotate clockwise, and the driving screw 203 drives the sliding table 205 and the sliding table 1 204 to drive the connecting plate 2 207 and its top electric suction cup 82 and the connecting plate 207 respectively. Plate 1 2061 and the electric clamp 9 on its top move, and the electric clamp 9 on the top of the sliding table 205 pushes the sheet to move. During the movement, the electric suction cup 82 located outside the glue spraying bin 5 and the electric telescopic rod 2 32 at the bottom are started, so that the output end of the electric suction cup 82 retracts and drives the support rod 81 and the electric suction cup 82 to descend, and then the bottom suction cup of the electric suction cup 82 contacts the sheet, and the electric suction cup 82 starts to absorb the sheet, and then the output end of the electric telescopic rod 2 32 extends and pushes the support rod 81, the electric suction cup 82 and the absorbed sheet to rise.

[0072] After the electric clamping jaw 9 delivers the clamped sheet to the center of the top of the processing table 1 , the other electric clamping jaw 9 will move away from the glue spraying chamber 5 .

[0073] The left and right electric slide rails 61 drive the front and rear electric slide rails 62 to move through the slide, and the front and rear electric slide rails 62 drive the positioning plate 63 and the glue spraying assembly 7 to move through the slide. The upper and lower electric slide rails 64 drive the left and right electric slide rails 61 and their bottom structures to move downward through the slide, and the glue pump 72 extracts glue, and the glue spraying head 73 sprays it onto the sheet to spray glue on the sheet.

[0074] During the glue spraying process, the two clamping jaws of the electric clamping jaws 9 release the sheet, and an anti-skid pad can be set on the top of the processing table 1 to prevent the sheet from shifting during the glue spraying process. The output end of the push motor 202 rotates counterclockwise to drive the driving screw 203 to rotate counterclockwise, and the driving screw 203 drives the sliding table 205 and the connecting plate 1 2061 to move to the return position. The moving distance is enough for the tooth plate 1 2064 to push the gear 31 to rotate half a circle, and then the electric telescopic rod 1 2063 on the left side of the processing table 1 works (see Figure 2 and Figure 4), the output end of the electric telescopic rod 1 2063 pushes the toothed plate 1 2064 to mesh with the gear 31 (the gear 31 is the gear 31 on the surface of the electric telescopic rod 2 32 at the bottom of the electric suction cup 82 that adsorbs the sheet), and then the output end of the push motor 202 rotates clockwise again to push the sliding table 1 204 and the sliding table 2 205 to move. During the movement of the sliding table 205, the gear 31 meshing with the toothed plate 1 2064 will rotate clockwise under the push of the toothed plate 1 2064. At this time, the gear 31 will synchronously drive the electric telescopic rod 2 32 and the fixed rod 33 as well as the support rod 81 and the electric suction cup 82 to rotate to the inner center of the glue spraying chamber 5, and the electric clamp 9 will also reset to its original position, and then the electric clamp 9 will start its clamping jaws to clamp the sheet to be sprayed with glue again; at the same time, the electric telescopic rod 3 41 starts to push the tooth plate 2 43 and the gear 31 to engage, limit the gear 31, and the output end of the electric telescopic rod 1 2063 pulls the tooth plate 1 2064 and the gear 31 to separate and reset.

[0075] After glue spraying, the left and right electric slide rails 61, the front and rear electric slide rails 62 and the upper and lower electric slide rails 64 work to reset the glue spraying assembly 7 to a position away from the glue-sprayed sheet (see the glue spraying bin 5 in the figure), and the output end of the electric telescopic rod 2 32 retracts and drives the support rod 81, the electric suction cup 82 and the adsorbed sheet to descend. After the adsorbed sheet contacts the glue spraying surface of the sheet sprayed with glue, the electric suction cup 82 stops adsorbing the sheet and presses the sheet down through the retraction force of the electric telescopic rod 2 32, so that the upper and lower sheets are firmly bonded.

[0076] The next sheet to be sprayed with glue is placed on one side of another electric clamp 9 , clamped by the electric clamp 9 and sent into the glue spraying chamber 5 . The sheet feeding process will push the bonded and laminated sheet out of the glue spraying chamber 5 .

[0077] After the glue spraying is completed and the glue spraying component 7 is reset, when the right electric telescopic rod 2063 pushes the tooth plate 2064 and the right gear 31 to engage, the left electric telescopic rod 2063 also synchronously pushes the tooth plate 2064 and the left gear 31 to engage. With the reset of the other electric clamp 9, the electric telescopic rod 2 32 and the adsorption component 8 inside the right gear 31 and the sheet adsorbed by the adsorption component 8 will be located on the top of the next sheet after glue spraying, and the adsorption component 8, lifting and rotating component 3 and other structures on the left side will be reset away from the glue spraying bin 5. At this time, the lifting and rotating component 3 and the adsorption component 8 away from the glue spraying bin 5 will adsorb the next sheet, wait for the glue spraying of the next sheet, and then carry out the next bonding and compounding. After that, the lifting and rotating components 3 and the limiting components 4 on the left and right sides will repeat continuously.

[0078] Except for the first time when the left electric telescopic rod 2063 is started and reset, the remaining times, each time the electric telescopic rod 2063 is started, the other electric telescopic rod 2063 will be started, which can ensure that the left and right adsorption components 8 and the lifting and rotating components 3 can work alternately.

[0079] Finally, according to the above operation, another limiting component 4, the lifting and rotating component 3 and the adsorption component 8 can complete the composite bonding of the sheet again, and then repeat the operation continuously. The device can meet the requirements of spraying glue, bonding and composite of the sheet both in the feeding and return process, which can improve efficiency.

However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
