Description

Technical Field

[0001] The utility model relates to the technical field of glue coating machines, in particular to a glue squeezing device used for structural glue. Background Art

[0002] Photovoltaic panels are installed on the roof using adhesive bonding. To reduce labor intensity, the glue application process uses a glue applicator. The glue applicator is equipped with a 2.6L rigid glue barrel. A motor drives a screw rod to push the bottom plug of the barrel to squeeze out the glue. However, the existing glue extrusion device uses a three-rod tensioning structure. The rods must both withstand the tension and position the rigid glue barrel. The three rods are arranged in a small semicircle, resulting in uneven loads and a high risk of tie rod breakage. Furthermore, when changing glue, the existing structure requires the glue pusher and the glue barrel to retreat simultaneously, which can cause the glue pusher seal and the limit block to squeeze and break.

[0022] In this embodiment, if Figure 1 and Figure 3 As shown, a glue squeezing device for structural glue includes a rear support 9 and a front support 3. A plurality of tie rods 1 are provided between the front support 3 and the rear support 9, and the tie rods 1 are symmetrically distributed. A glue barrel 5 is provided between the tie rods 1 and is placed in a glue barrel sleeve 4. A glue outlet 2 is provided on the front support 3, and the glue outlet 2 is connected to the outlet of the glue barrel sleeve 4. A glue pushing mechanism is provided at the rear end of the glue barrel 5. A notch 21 is provided at the end of the glue barrel sleeve 4. A mounting plate 19 is mounted on the side of the front support 3, and a hook 20 corresponding to the notch 21 is provided on the mounting plate 19. By symmetrically arranging the tie rods 1 between the front support 3 and the rear support 9, the force is evenly distributed, thereby improving the structural strength of the device. At the same time, the notch 21 is provided at the end of the glue barrel sleeve 4. When the glue needs to be replaced, because the hook 20 is hooked in the notch 21, the glue pushing head 8 will not move synchronously with the glue barrel 5, and the sealing ring 7 on the side of the glue pushing head 8 will not be squeezed a second time, thereby extending the service life.

[0023] Furthermore, there are four tie rods 1, distributed in a rectangular arrangement between the front support 3 and the rear support 9. A pressure block 6 is slidably mounted on the upper two tie rods 1. The lower surface of the pressure block 6 has a pressure groove 15, which mates with the surface of the rubber drum sleeve 4. Specifically, the rubber drum 5 is placed within the rubber drum sleeve 4, which is then placed between the front support 3 and the rear support 9. The pressure block 6 is then slid so that the pressure groove 15 mates with the surface of the rubber drum sleeve 4, thereby achieving positioning.

[0024] In this embodiment, the glue pushing mechanism includes a glue pushing head 8, which is located at the rear end of the glue barrel 5 and is installed at the end of a screw 11. Preferably, a sealing groove is provided on the side of the glue pushing head 8, and a sealing ring 7 is installed in the sealing groove. The screw 11 passes through the rear support 9, and an anti-rotation frame 12 is installed on the other side of the rear support 9. An anti-rotation rod 13 is provided on the anti-rotation frame 12. The anti-rotation rod 13 passes through the other end of the screw 11, and the screw 11 is rotated by a reduction motor 14, and the reduction motor 14 is installed on the rear support 9. Further, as Figure 2 As shown, a turntable is spirally mounted on the lead screw 11, with a driven pulley 17 mounted on its outer side. The power output of the reduction motor 14 is connected to the driving pulley 16, and power is transmitted between the driving pulley 16 and the driven pulley 17 via a synchronous belt 10. Furthermore, the anti-rotation frame 12 is U-shaped, with a movable groove 18 defined in the middle of both the upper and lower flat plates. The anti-rotation rod 13 is equipped with a roller, which is located within the movable groove 18. A slide rail is also provided on the surface of the upper flat plate, and a slider is provided at the end of the anti-rotation rod 13, which is slidably mounted on the slide rail. Preferably, a limit block is fixedly mounted on the slide rail. Specifically, first, the rubber pushing head 8 and the pressure block 6 are retreated to the original position, that is, close to the rear support 9, the rubber barrel 5 is placed in the rubber barrel sleeve 4, and then the rubber barrel sleeve 4 is placed between the front support 3 and the rear support 9, so that the glue outlet 2 is connected to the outlet of the rubber barrel sleeve 4, and the rubber pushing head 8 is located at the rear end of the rubber barrel 5. Then, the rubber barrel sleeve 4 is rotated so that the hook 20 is hooked in the notch 21, and the pressure block 6 is slid so that the pressure groove 15 fits the surface of the rubber barrel sleeve 4, thereby positioning. After the positioning is completed, the reduction motor 14 is started to drive the driving wheel 16 to rotate. Since the driving wheel 16 and the driven wheel 17 are driven by the synchronous belt 10, the driven wheel 17 rotates, causing the screw 11 to move to the The rubber pushing head 8 moves forward to squeeze the glue. During the forward movement of the lead screw 11, the roller moves synchronously in the moving groove 18. When the slider at the end of the anti-rotation rod 13 contacts the limit block on the slide rail, the reduction motor 14 reverses and drives the rubber pushing head 8 to retreat. During the retreat of the rubber pushing head 8, since the hook 20 is hooked in the notch 21, the rubber pushing head 8 will not move synchronously with the rubber barrel 5, and the sealing ring 7 on the side of the rubber pushing head 8 will not be squeezed for the second time, thereby extending the service life. When the rubber pushing head 8 retreats to the original position, the pressure block 6 is dialed to the original position, the rubber barrel sleeve 4 is rotated in the opposite direction, the hook 20 is removed from the notch 21, and finally the rubber barrel is removed to complete the glue squeezing.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
