A rubber four-roll calender is often used in rubber calendering. However, when the existing rubber four-roll calender is in use, the rubber is uneven after passing through the press rollers, and cutting tools are needed to trim the overflowing edges, resulting in a large amount of subsequent cutting work, which is very troublesome. Therefore, a low-noise four-roll calender is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0022] The following describes a low-noise four-roll calender provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0023] Embodiment:

[0024] Combined with Figures 1-6 As shown, a low-noise four-roll calender provided by the present utility model includes a base 1. An inlet guide member 2 is fixedly installed on the inner wall of the base 1. A feed pipe 3 is fixedly connected to the top of the inlet guide member 2. The inlet guide member 2 and the feed pipe 3 form an integral body, mainly used to guide excess rubber fragments and prevent side leakage. A collection drawer 4 is slidably connected inside the inlet guide member 2. The inside of the inlet guide member 2 communicates with the collection drawer 4. When the device starts to operate, a large amount of rubber debris will fall into the inlet guide member 2 through the feed pipe 3 and then fall into the collection drawer 4 to be discharged for secondary processing. A transition member 5 is fixedly installed in the middle of the inlet guide member 2. The rolled rubber will fit onto the top of the transition member 5 and enter the next process, playing a role of transition and traction. A cavity is formed inside the transition member 5, and a dropping hole 12 is formed at the top of the transition member 5. A scraping shovel 19 is arranged on one side of the transition member 5. The top end of the scraping shovel 19 is in contact with the fourth calender roll 6. The scraping shovel 19 shovels off the rubber particles adhered to the fourth calender roll 6. Due to the presence of the dropping hole 12, the rubber particles will fall into the transition member 5, and the transition member 5 communicates with the inlet guide member 2, that is, the debris will all fall into the collection drawer 4 and be taken away.

[0025] Among them, a servo motor 11 is fixedly installed on one side of the base 1. A fourth calender roll 6 is fixedly installed on the transmission end of the servo motor 11. The fourth calender roll 6 is responsible for transporting the rubber sheet. A second calender roll 7 is sleeved at a position inside the base 1 close to the fourth calender roll 6. According to the existing device, the positional relationship between the fourth calender roll 6, the second calender roll 7, and other calender rolls can be adjusted to change the thickness of the rubber. This description will not elaborate further. A top cover 8 is welded to the top of the base 1. A third calender roll 9 is sleeved inside the top cover 8. A first calender roll 10 is sleeved at a position inside the top cover 8 close to the third calender roll 9. The number of servo motors 11 is two groups of four. The transmission ends of the four servo motors 11 are respectively fixedly connected to the second calender roll 7, the third calender roll 9, and the first calender roll 10, that is, each calender roll has an independent driving device to achieve the pressing of the rubber. This is also the structure possessed by the calender.

[0026] Furthermore, large gears 13 are fixedly installed at both ends of the fourth pressure roller 6. When the servo motor 11 drives the fourth pressure roller 6 to rotate, the large gears 13 will also rotate synchronously, transmitting the acting force to the meshing parts to achieve transmission. A connecting piece 14 is sleeved in the middle of the large gear 13. One side of the connecting piece 14 is welded to the base 1. A clamping piece 15 is clamped at the top of the connecting piece 14. A small gear 16 is sleeved in the middle of the clamping piece 15. The teeth of the small gear 16 mesh with those of the large gear 13. That is, when the large gear 13 rotates, it will synchronously drive the small gear 16 to rotate, and then drive the clamping piece 15 to rotate to achieve transmission. A knife gate wheel 17 is welded to one side of the small gear 16. The bottom of the feed pipe 3 is in contact with the fourth pressure roller 6. The width of the inlet of the feed pipe 3 is the same as the height of the knife gate wheel 17. A cutting blade 18 is fixedly installed on one side of the knife gate wheel 17. The cutting blade 18 will cut the overflowing part of the rubber. The cut rubber is then chopped into granules by the knife gate wheel 17 and then falls into the feed pipe 3 and is discharged.

[0027] The working principle and usage process of the present utility model are as follows: First, after the device is started, the rubber will be initially rolled under the action of the second pressure roller 7 and the first pressure roller 10. At this time, the rubber will be conveyed to the pressing area between the fourth pressure roller 6 and the third pressure roller 9. During the same process, the rubber will be pressed to overflow the unusable rubber edges. At this time, the servo motor 11 will drive the fourth pressure roller 6 to rotate, synchronously driving the large gear 13 to rotate, and then driving the small gear 16 to rotate. At this time, the small gear 16 will further drive the knife gate wheel 17 and the cutting blade 18 to rotate. At this time, the cutting blade 18 will cut off the overflowing rubber edges, and simultaneously the knife gate wheel 17 will chop the rubber into pieces. The rubber debris will be brought into the feed pipe 3. At this time, the rubber debris will fall from the feed pipe 3 into the inside of the guiding part 2 and enter the collection drawer 4, waiting to be discharged.

[0028] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
