Description

Technical Field

[0001] The invention relates to the technical field of rubber mixing, in particular to an anti-deformation structure for a scraper device of a rubber mixing machine. Background Art

[0002] At present, the rubber mixing machine is used in conjunction with the main scraper frame. The main function of the main scraper frame is to make the rubber material bulge and increase dispersion. However, if the main scraper frame is too long, it will deform into a U shape due to gravity over time. The deformed part will be in direct contact with the roller, causing friction and temperature rise. When the temperature is high, there will be more sticky material, which can easily lead to quality problems.

[0003] In the prior art, a patent with announcement number CN209111280U discloses a rubber mixing machine scraper device, including a scraper frame and an adjusting mechanism, wherein a scraper is mounted on the scraper frame, and the adjusting mechanism is arranged below the scraper frame. The adjusting mechanism includes a pressure rod, a buffer device, a U-shaped bracket and an adjusting screw, wherein the upper end of the pressure rod is connected to the scraper frame, and the buffer device is arranged below the pressure rod, and the buffer device includes a spring, a spring groove and two sets of sliders.

[0004] The above structure can absorb and buffer vibrations through the setting of springs, and reduce deformation of the scraper and the scraper holder. However, screws are usually used to support the vertical knife against the holder directly below. The holder is subjected to pressure from directly above, and the deformation is further aggravated, which cannot solve the deformation problem of the holder. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide an anti-deformation structure for a rubber mixer scraper device to solve the problem that the blade holder is further deformed by the pressure from above and the deformation of the blade holder cannot be solved.

[0006] Based on the above purpose, the present invention provides an anti-deformation structure for a scraper device of a rubber mixer, comprising a main scraper frame, a scraper device is arranged inside the main scraper frame, and an upper scraper frame is fixedly installed on the top of the main scraper frame;

[0007] The scraper device includes multiple groups of vertical knives distributed inside the main scraper frame, and special gaskets are arranged on the top of the multiple groups of vertical knives. The top of the special gasket is connected to a pressure plate, and a fixing screw is connected through the special gasket and the pressure plate. The bottom end of the fixing screw extends to the top of the vertical knife, and an upper pull screw is fixedly connected between the pressure plate and the upper knife frame.

[0008] Preferably, at least four groups of the vertical knives and special gaskets are provided, and the pressure plate and the upper knife holder are arranged vertically and parallelly.

[0009] Preferably, the plurality of groups of vertical knives are equidistantly arranged inside the main scraper frame, and the bottom ends of the vertical knives abut against the top of the main scraper frame.

[0010] Preferably, the length of the special gasket is less than the length of the vertical knife, and the special gasket is in a strip structure.

[0011] Preferably, the vertical knife and the main scraping knife holder are vertically arranged corresponding to each other, and the vertical knife and the main scraping knife holder are fixedly connected by screws.

[0012] Preferably, the upper pull screw is arranged at the center of the upper knife holder and the pressing plate.

[0013] Preferably, the main scraping knife holder is in a straight shape structure, and multiple groups of reinforcing ribs are arranged inside the main scraping knife holder.

[0014] Advantages of the present invention:

[0015] Through the deformation adjustment by pulling up the upper pull screw between the pressing plate and the upper knife holder in the scraping knife device, and fixing and supporting the special gasket and the pressing plate through the fixing screws on both sides. When the pressing plate is pulled up, the vertical knife will be suspended. Through the special gasket between the pressing plate and the vertical knife, the loosening of the vertical knife is prevented, and the weight accumulation on the main scraping knife holder is avoided, thereby solving the deformation problem of the main scraping knife holder.

The pressure plate 4 in the scraping knife device and the upper knife frame 5 are pulled upward by the upper pulling screw 6 for deformation adjustment. On both sides, the special gasket 3 and the pressure plate 4 are fixedly supported by the fixing screw 7. When the pressure plate 4 is pulled upward, the vertical knife 2 will be suspended. Through the special gasket 3 between the pressure plate 4 and the vertical knife 2, the vertical knife 2 is prevented from loosening, avoiding the weight accumulation on the main scraping knife frame 1, and thus solving the deformation problem of the main scraping knife frame 1.

[0025] As an embodiment, as Figure 1 、 Figure 2 、 Figure 3 shown, there are four groups of vertical knives 2 and special gaskets 3, and the pressure plate 4 and the upper knife frame 5 are arranged parallel to each other up and down.

[0026] In this embodiment, with the design of multiple groups of vertical knives 2 and special gaskets 3, when the pressure plate 4 is pulled upward, the vertical knife 2 will be suspended. The pressure plate 4 and the upper knife frame 5 are pulled upward by the upper pulling screw 6 for deformation adjustment.
