Technical Field

[0001] The utility model relates to the technical field of scraping mechanisms, in particular to a scraping mechanism for laminated glass. Background Art

[0002] Laminated glass is a type of safety glass consisting of two or more layers of glass and a layer of PVB film in between. That is, when the glass breaks, the film can effectively fix the fragments so that they will not fly everywhere. During processing, the pre-treated glass piece is placed on a flat workbench, and the PVB laminated film is placed in the middle of the glass piece. Then, it is covered with a layer of silicone and flattened by hand or with a pressure roller. When laminating, the glass piece needs to be wiped repeatedly to ensure that its surface is dust-free, and then it is covered on the silicone, pressed tightly and the surface bubbles are removed.

[0003] After the laminated glass is compressed by the peritoneum, it is necessary to remove the bubbles between the glass and the silicone by pushing and scraping. However, in the existing technology, when hanging the material, the scraper in some scraping mechanisms is perpendicular to the glass, which cannot play the role of pushing the material, making it inconvenient to push out the bubbles between the silicone and the glass, and the scraping effect is poor. Although the scraper in some scraping structures is inclined, its inclination direction is fixed and cannot be adjusted according to the moving direction during the reciprocating movement, resulting in low scraping efficiency.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] like Figure 1-4As shown, the utility model provides a scraping mechanism for laminated glass, including a screw assembly 1 and a servo motor 2. The screw assembly 1 includes a slide rail, a screw and a movable sleeve block. The interior of the slide rail is rotatably connected to the screw through a bearing, and a movable sleeve block is provided on a threaded sleeve of the screw. The movable sleeve block is slidably arranged inside the slide rail, and the movable sleeve block extends to the outside of the slide rail and is fixed to the top surface of the support plate 4. The output shaft of the servo motor 2 rotates and passes through the slide rail and is fixed to the screw. Mounting plates 3 are fixed on both sides of the screw assembly 1, and fixing holes are provided inside the mounting plates 3. The sum of the widths of the screw assembly 1 and the two mounting plates 3 is greater than the width of the support plate 4. The output end of the screw assembly 1 is fixed with a support plate 4. The bottom of the support plate 4 is symmetrically and adjustably connected to the support frame 5, and a scraper 6 is rotatably sleeved inside each support frame 5, and a rotating crank handle 7 is fixed at both ends of the scraper 6. Each rotating crank handle 7 rotates through the support frame 5, and a support rod 8 is fixed on the outer wall of the support frame 5 at the bottom of each rotating crank handle 7. A rotating sleeve 9 is rotatably sleeved on the outside of the rotating crank handle 7 and the support rod 8. A spring 10 is fixed between the two rotating sleeves 9 on each side. The outer surfaces of the support frame 5 on both sides of the lower part of the rotating crank handle 7 are symmetrically fixed with limited support blocks 11. A positioning lever 12 is symmetrically provided at the bottom of the end of the screw assembly 1 close to the servo motor 2, and the lower part of the scraper 6 is flush with the top of the positioning lever 12.

[0024] The following is a detailed description of the specific settings and functions of this embodiment: the support rod 8 on the outside of each rotating crank 7 is set to a horizontally placed "T" shape, and the support rod 8 on the outside of the support frame 5 is set to a horizontally placed "I" shape to prevent the rotating sleeve 9 from separating from the support rod 8, and ensure that the rotating sleeve 9 can only rotate on the support rod 8. Each group of two limiting support blocks 11 are in an inverted "eight" shape, which is convenient for the limiting support blocks 11 to support and limit the rotating crank 7, so that the scraper 6 can be stably maintained after being flipped and tilted. Each rotating crank 7 is in the same straight line with the scraper 6, and the bottom corners of the scraper 6 are set to arc shape to avoid indentations caused by the scraper 6 squeezing the scraping material.

[0025] Example 2

[0026] like Figure 1-4 As shown, the support plate 4 is symmetrically provided with adjustment grooves, and the adjusting grooves are all slidably sleeved with movable sleeves 13, each movable sleeve 13 is arranged in an "I" shape, and the movable sleeve 13 is provided with a sliding hole that cooperates with the output rod of the servo cylinder 14. The length of each fixed clamping block 15 is greater than the length of the sliding groove, and the top of the movable sleeve 13 is provided with a servo cylinder 14, and the output rod of the servo cylinder 14 slides through the movable sleeve 13 and is fixed to the top surface of the support frame 5. The movable sleeve 13 on the bottom surface of the support plate 4 is threaded with a fixed clamping block 15.

[0027] The effect achieved by the entire embodiment is that when scraping, the movable sleeve 13 operates to push the support frame 5 downward through the output rod, thereby driving the scraper 6 to move downward until it abuts against the glass. The sliding hole facilitates the sliding of the output rod inside the movable sleeve 13, and the "I"-shaped design of the movable sleeve 13 prevents the movable sleeve 13 from separating from the servo cylinder 14, and also ensures that the fixed clamp 15 can clamp and fix the support plate 4.

[0028] The use method and working principle of this device: When scraping is required, the screw assembly 1 is mounted above the operating table through the mounting plate 3, and then the overall width of the two scrapers 6 is adjusted according to the width of the glass. When adjusting, the fixed clamping block 15 is twisted to release the clamping fixation of the fixed clamping block 15 on the support plate 4, and the support frame 5 can be rotated to adjust the overall linear width of the scraper 6. After the adjustment is completed, the fixed clamping block 15 is twisted again to re-clamp the servo cylinder 14. When scraping, the servo cylinder 14 pushes the support frame 5 downward, driving the scraper 6 to abut against the glass. The servo cylinder 14 can control the scraping pressure. At the same time, the screw assembly 1 and the servo motor 2 are running, driving the scraper 6 to move for scraping. After a single pass of scraping is completed, since the lower part of the scraper 6 is flush with the top of the positioning lever 12, the screw assembly 1 continues to drive the scraper 6 to move until the positioning lever 12. At this time, the scraper 6 rotates and flips under the push of the positioning lever 12. When the scraper 6 rotates, it drives the rotating crank 7 to rotate. After the rotating crank 7 is rotated and flipped 90°, the scraper 6 flips to the reverse tilt. At this time, the screw assembly 1 drives the support frame 5 to move in the reverse direction, and scraping can be carried out.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
