Features: impact resistance, unbreakable, hundreds of times stronger than tempered glass and acrylic board, tough and safe, anti-theft, and best bulletproof effect.

[0003] At present, the endurance board will go through the processes of traction and cooling after blow molding, and then the cooled and molded endurance board will be transported along the conveyor belt. However, at this time, the two sides of the endurance board will be uneven. At this time, edge cutting is required to make the edges of both sides of the endurance board flat, that is, the waste edge cutting process. The existing motor-driven saw blade is generally used for cutting, but a large amount of debris will be generated during the cutting process. If it is not cleaned in time, it will interfere with the subsequent cutting. Manual cleaning is labor-intensive and there are safety hazards. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0025] like Figures 1 to 4 As shown, a waste edge cutting device for endurance board includes a conveyor belt 1 and a cutting assembly. A U-shaped processing table 2 with a constant height is arranged on one side of the end of the conveyor belt 1. A mounting frame 3 and symmetrically distributed blanking troughs 21 are arranged on the U-shaped processing table 2. An electric push rod 31, symmetrically distributed negative pressure fans 35 and a through hole 36 arranged opposite to the negative pressure fan 35 are arranged on the mounting frame 3. The electric push rod 31 is connected to a connecting plate 32. The connecting plate 32 is symmetrically provided with a cutting assembly matched with the blanking trough 21. Specifically, the cutting assembly includes a driving motor 33 and a saw blade 34. The cutting assembly has been shown in the figure to adopt the existing technology without improvement. A metal filter 39 is arranged on the side of the through hole 36 away from the negative pressure fan 35.

[0026] Further refinement of the embodiment of the present utility model is as follows: Figure 2 and Figure 3 As shown, two groups of placement rods 37 are symmetrically arranged on the inner side of the mounting frame 3, one group of placement rods 37 includes two placement rods and a slot 371 is opened on the placement rod 37, a metal filter 39 is inserted into the slot 371, and a limiting plate 38 is arranged at one end of the placement rod 37; the slot 371 and the limiting plate 38 can facilitate the installation, positioning and disassembly of the metal filter 39, so that the metal filter 39 can be replaced regularly to ensure the suction effect of the debris.

[0027] Further refinement of the embodiment of the present utility model is as follows: Figure 1 and Figure 4As shown, a mounting groove is provided inside the U-shaped processing table 2, and the mounting groove is not numbered in the figure. The mounting groove is connected with the blanking groove 21, and a waste box 22 is movably installed in the mounting groove. Specifically, the waste box 22 is slidably fitted in the mounting groove, and a handle 23 is provided on the waste box 22. The handle 23 can be used to regularly take out the waste box 22 from the inside of the U-shaped processing table 2 to dump the internal debris.

[0028] It should be noted that the conveyor belt 1, the cutting assembly, the electric push rod 31 and the negative pressure fan 35 are all electrically connected to the controller, which is not shown in the figure.

[0029] The workflow of this utility model:

[0030] First, the long section of endurance board after cooling and forming is transported to the U-shaped processing table 2 along the conveyor belt 1 (effectively limited during the conveying process of the conveyor belt 1, the specific limiting means is not shown in this application, and the cylinder is used to drive the mounting plate equipped with rollers to move from both sides to the center without affecting the normal transportation of the endurance board and the endurance board will not be offset. This method belongs to the existing technical means and is not improved). Then the endurance board continues to move along the U-shaped processing table 2. At the same time, the controller controls the electric push rod 31 to drive the two groups of cutting components to synchronously descend to the top of the blanking chute 21, and then the cutting components start working. As the polycarbonate sheet is continuously conveyed forward, the uneven waste edges on both sides will come into contact with the cutting components, and the assembly line cutting process will begin. Debris will be generated during the cutting process, and the controller will control the negative pressure fans 35 on both sides to work synchronously, and then generate suction force through the through holes 36. At this time, the debris generated during the cutting process will be sucked and adsorbed on the metal filter 39, which will not affect the subsequent cutting, and significantly reduces the labor intensity and safety hazards of the existing manual collection of debris. After the waste edge cutting of a batch of polycarbonate sheets is completed, the entire equipment will be shut down and the metal filter 39 can be replaced.

[0031] In some embodiments, Figure 3 As shown, a cylinder 41 is provided on the limit plate 38, and the cylinder 41 is connected to a scraper 42 which contacts the outer surface of the metal filter 39 and is distributed front and back. In this embodiment, the cylinder 41 drives the scraper 42 to move, so as to clean the main adsorption area of ​​the outer surface of the metal filter 39 to scrape off a part of the attached debris into the blanking chute 21 (the negative pressure fan is briefly stopped during scraping). In this way, the service life of the metal filter 39 can be extended without frequent shutdown for replacement and cleaning.

[0032] The above embodiment is further optimized in that the limit plate 38 is a magnetic plate. In this embodiment, when the metal filter 39 contacts the limit plate 38, an adsorption force is generated. When the scraper 42 moves subsequently, the metal filter 39 is not easily displaced, and the fixing effect is better.

[0033] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
