Description

Technical Field

[0001] This utility model relates to the field of blow molding barrel processing technology, specifically to a device for removing flash from blow molding barrels. Background Technology

[0002] Blow-molded buckets are plastic containers formed using a blow molding process. They are typically made of thermoplastic materials such as polyethylene and are mainly used for packaging, storage, and transportation. The production process involves blowing molten plastic through a mold to form a hollow product, which is then demolded after cooling. This process is characterized by high production efficiency, high material utilization, and low cost, making it suitable for large-scale production.

[0003] After blow molding, strip-shaped flash will appear on the surface of the blow molded bucket. Currently, when removing the flash, a scraper is used to treat the surface of the blow molded bucket, and the bucket is placed on the device by hand to fix it for flash removal. Because there are flash removal structures at both the top and bottom of the flash removal device, the blow molded bucket cannot be placed quickly, and workers are prone to accidentally touching the scraper, causing hand injuries. In addition, the flash removed cannot be collected when removing the flash from the blow molded bucket, resulting in a mess above the working device. Utility Model Content

[0029] Mounting plate 8 is installed on the left side of connecting block 7. Mounting plate 8 has a bracket 9 fixed at its upper end and a first fixing strip 10 fixed at its lower end. A first telescopic rod 11 is fixedly installed inside the first fixing strip 10 and a slider 12 is installed on the right side of the first telescopic rod 11. A replacement frame 13 is fixedly installed at the lower end of slider 12 and a first insertion block 14 is installed inside the replacement frame 13. A scraper 15 is fixedly connected to the lower end of the first insertion block 14.

[0030] For example, such as Figure 3 As shown, a second fixing strip 16 is fixedly installed at the lower end of the mounting plate 8, and a second telescopic rod 17 is installed inside the second fixing strip 16. A slider 2 18 is installed on the right side of the second telescopic rod 17, and a replacement frame 2 19 is fixedly installed at the upper end of the slider 2 18. A second insertion block 20 is installed inside the replacement frame 2 19, and a scraper 21 is fixedly connected to the lower end of the second insertion block 20.

[0031] For example, such as Figure 2 As shown, the support rod 1 is rectangular in shape and there are four of them. The collection box 4 is a detachable structure. The drop opening 3 is U-shaped and the connecting block 7 is L-shaped.

[0032] For example, such as Figure 2 As shown, the lower right side of the mounting plate 8 and the left side of the connecting block 7 form a fixed installation. The first fixing strip 10 is fixedly installed between the bracket 9 and the upper end of the mounting plate 8. A sliding groove is provided inside the first fixing strip 10.

[0033] For example, such as Figure 3 As shown, slider 12 is slidably connected to the inner groove of the first fixed strip 10 via the first telescopic rod 11, and replacement frame 13 is interlocked with the first insertion block 14. The upper end of scraper 15 is shaped like a square.

[0034] For example, such as Figure 3 As shown, the second fixing strip 16 has the same structure as the first fixing strip 10. The second slider 18 is connected to the inner groove of the second fixing strip 16 through the second telescopic rod 17. The upper end of the scraper 21 is semi-arc-shaped.

[0035] In some examples, support rod 1 fixes workbench 2 to the ground. Workbench 2 has a flash drop opening 3 on the left side and a groove 5 on the right side. Flash collection box 4 is placed directly below the drop opening 3. The blow molding barrel is fixed in place on workbench 2. The PLC controller activates push rod 6 installed in groove 5.

[0038] In some examples, the blow-molded barrel is placed into the clamping structure, and the controller activates multiple electric rods 23 on the upper end of the first side plate 22. The electric rods 23 drive the upper silicone pads 24 to move. The elastic deformation of the silicone pads 24 adapts to and fixes the upper part of blow-molded barrels of different shapes and sizes. At the same time, the controller activates the electric rods 23 and the lower hydraulic rods 25. The hydraulic rods 25 drive the fixed rings 26 connected to them to move, thereby adapting to and fixing the lower part of blow-molded barrels of different sizes. After the blow-molded barrel is completely fixed, the controller activates the push rods 6 located in the groove 5 to perform subsequent processing on the blow-molded barrel.
