[0030] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0031] Please refer to Figures 1-8 The embodiment of the utility model provides a precise gluing tool for plastic protective film, including a gluing platform 1, a feeding roller 2 is rotatably provided on the lower side of one end of the gluing platform 1, and the rolled protective film to be glued is put on the feeding roller 2. Since a tensioning roller 3 is installed on the upper side of one end of the gluing platform 1, and a pair of conveying rollers 4 are rotatably provided on the gluing platform 1 on the side of the tensioning roller 3, the protective film is then passed over the upper end of the tensioning roller 3 and through the middle of the pair of conveying rollers 4. The protective film is conveyed by the rotation of the conveying roller 4, thereby improving the efficiency of gluing.
[0032] At the same time, a gluing platform 5 is installed at the upper end of the gluing station 1. After the protective film comes out of the conveying roller 4, it is spread flat on the gluing platform 5. The height of the gluing platform 5 is consistent with the conveying height of the conveying roller 4. Of course, a section of protective film can also be directly spread flat on the gluing platform 5 for gluing.
[0033] like Figure 2As shown, slide rails 6 are provided on both sides of the gluing platform 5, and both ends of the movable bracket 8 slide in the slide rails 6 respectively. A gluing mechanism is installed on the movable bracket 8, and the gluing mechanism is used to gluing the flat protective film.
[0034] Specifically, the gluing mechanism includes a cylinder 9 installed at both ends of the mobile bracket 8, the piston end of the cylinder 9 is connected to the mounting rod 10, and the lower end of the mounting rod 10 is rotatably provided with a gluing roller 12. According to the thickness of the glue required, the height of the gluing roller 12 is adjusted by the cylinder 9. When the motor drives the screw 7 set in one of the slide rails 6 to rotate, the mobile bracket 8 is prompted to move. At this time, the gluing roller 12 rolls and coats the glue extruded on the protective film.
[0035] In order to make the glue automatically dissolve, an adjusting frame 13 is provided at the upper end of the movable bracket 8, and a moving block 15 is slidably installed in the groove opened at the upper end of the adjusting frame 13. A cylinder 2 16 is installed on one side of the moving block 15, and the lower end of the cylinder 2 16 is connected with a fixed plate, and a glue head 17 is placed on the fixed plate. The glue head 17 is connected to the delivery pump 18 through a pipeline, and the delivery pump 18 transports the glue in the glue cylinder 19 to the glue head 17 through the pipeline. The glue head 17 transports the glue to the protective film on one side of the glue coating roller 12. Before dissolving the glue, the cylinder 2 16 lowers the position of the glue head 17 to prevent glue from splashing. When dissolving the glue, the motor drives the screw rod 3 14 installed in the groove of the adjusting frame 13 to rotate, so that the moving block 15 threadedly connected to the screw rod 3 14 moves, thereby realizing mobile dissolving of the glue and improving the uniformity of the glue coating.
[0036] Furthermore, a glue cleaning component is installed on the glue coating mechanism, which removes the glue on the glue coating mechanism to prevent the glue from drying on the glue coating roller 12. Specifically, a horizontal plate 20 is slidingly provided in the groove opened at the upper end of the mounting rod 10, and plug rods 21 are inserted at both ends of the horizontal plate 20. The plug rods 21 are adjusted in height by sliding on the horizontal plate 20. The lower ends of the two plug rods 21 are slidably matched with the cleaning sleeve 1 22 and the cleaning sleeve 2 23 respectively. By sliding the cleaning sleeve 1 22 and the cleaning sleeve 2 23 outward, the two can wrap the glue coating roller 12. The sliding of the horizontal plate 20 in the groove of the mounting rod 10 is used to clean the glue coating roller 12, thereby reducing cleaning dead angles.
[0037] The insertion rod 21 is fixed by a latch 24 , thereby improving the stability of the insertion rod 21 .
[0038] A slot 26 is provided at the upper end of the cleaning sleeve 1 22. When the cleaning sleeve 1 22 and the cleaning sleeve 2 23 are fitted together, the protrusion 25 provided at the upper end of the cleaning sleeve 23 engages with the slot 26, thereby improving the stability of the cleaning sleeve 1 22 and the cleaning sleeve 2 23 during cleaning and improving the cleaning efficiency.
[0039] In addition, a screw rod 11 is rotatably provided in a groove opened at the upper end of the mounting rod 10 , and the screw rod 11 is threadedly connected to the transverse plate 20 . When the screw rod 11 is rotated, the transverse plate 20 moves stably to ensure the force of cleaning the glue coating roller 12 .
[0040] In summary, the working principle of the precise gluing tool for plastic protective film of the embodiment of the present invention is as follows: when applying glue, the delivery pump 18 is used to deliver glue to the glue head 17, the cylinder 2 16 lowers the height of the glue head 17, the moving block 15 moves the glue head 17 to apply glue, and the glue is evenly squeezed onto the protective film on one side of the glue roller 12, the screw 1 7 rotates to move the movable bracket 8, and the glue roller 12 rotates to apply glue;
[0041] After the gluing is completed, the insertion rod 21 is slid downward so that the cleaning sleeve 1 22 and the cleaning sleeve 2 23 are respectively located on both sides of the gluing roller 12, and then the cleaning sleeve 1 22 and the cleaning sleeve 2 23 are close to each other to wrap the gluing roller 12, and the screw rod 2 11 is rotated to move the cross plate 20 with the cleaning sleeve 1 22 and the cleaning sleeve 2 23 to clean the glue on the gluing roller 12.
[0042] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
