Technical Field
[0001] The utility model relates to the technical field of sugar cane pressing equipment, in particular to a waterproof device for the bearing bushes of a press Background Art
[0002] Sugar manufacturing enterprises in southern China mainly use sugar cane as raw materials for production. In order to extract sugar from sugar cane, sugar manufacturing enterprises will use a three-roll press to press sugar cane. The three-roll press has a total of three large pressing rolls, which are arranged in a triangular formation on the press. The top pressing roll is called the top roll, and the two lower pressing rolls are called the front roll and the rear roll. When the press is working, through the cooperation of the three rolls, pressure is applied to the sugar cane filaments, so that the cane juice is squeezed out. After subsequent concentration, crystallization and other treatments, the common white granulated sugar can be obtained. During pressing, a large amount of cane juice will be discharged from both sides of the top roll through the coupling holes of the top roll of the press. The discharged cane juice is easy to drip onto the bearing bushes at the journal necks of the front roll and the rear roll. Due to improper sealing of the bearing bushes, the cane juice is very easy to enter the bearing bushes, damaging the lubricating oil film and severely wearing the bearing bushes and the journal necks. According to calculations, for a bearing bush with good lubrication, the wear amount per sugar pressing season is only 0.5 mm to 1 mm, while for a bearing bush that has entered cane juice, the wear amount per sugar pressing season is 3 mm to 6 mm. Seriously, it may also cause the phenomenon of bearing bush burning and lead to shutdown accidents. Therefore, a waterproof device for the bearing bushes of a press is needed to prevent the cane juice discharged from the top roll from entering the bearing bushes of the front roll and the rear roll to damage the oil film and extend the service life of the roll shaft and the bearing bushes. Content of the Utility Model
[0003] In order to solve the above problems, the utility model proposes a waterproof device for the bearing bushes of a press, which can prevent the cane juice discharged from the top roll from entering the bearing bushes of the front roll and the rear roll to damage the oil film and extend the service life of the roll shaft and the bearing bushes.

[0021] As Figures 1 to 2 shown, an embodiment of the present utility model provides a waterproof device for the bearing bush of a press, including: a frame 1, on which a bearing bush seat 2 is installed, and a bearing bush 5 is provided on the bearing bush seat 2; a press roller 3, on which an axial lotus root tube hole 8 is provided, and roller shafts 4 are provided on both sides of the press roller 3. The roller shafts 4 on both sides of the press roller 3 are installed on the frame 1 through the bearing bush 5 and the bearing bush seat 2; wherein, an upper bearing bush cover 6 is provided on the upper part of the roller shaft 4, the lower part of the upper bearing bush cover 6 is connected to the bearing bush seat 2, the upper bearing bush cover 6 and the bearing bush seat 2 surround the roller shaft 4, and the side surface of the upper bearing bush cover 6 is flush with the side surface of the bearing bush seat 2; a rubber plate 7 is provided on the frame 1, the upper part of the rubber plate 7 is connected to the frame 1, an arc-shaped notch is provided in the lower part of the rubber plate 7, and the middle part of the rubber plate 7 blocks between the lotus root tube hole 8 and the upper bearing bush cover 6.
[0022] When the press works, pressure is applied to the sugarcane filaments through the press roller 3 so that the sugarcane juice is squeezed out. Part of the sugarcane juice will flow out from the side of the press roller 3 through the lotus root tube hole 8. When the sugarcane juice flowing down from the lotus root tube hole 8 of the top roller comes down, the rubber plate 7 will isolate the sugarcane juice outside the sealing ring 9, preventing the sugarcane juice from dripping onto the joint between the sealing ring 9 and the upper bearing bush cover 6, effectively preventing the sugarcane juice from entering the bearing bush 5 and damaging the oil film, making the lubrication between the roller shaft 4 and the bearing bush 5 good, and extending the service life of the roller shaft 4 and the bearing bush 5. The arc-shaped notch is provided in the lower part of the rubber plate 7, so that the rubber plate 7 is more fittingly installed on the roller shaft 4, increasing the blocking area and improving the effect of blocking the sugarcane juice.
[0023] Specifically, sealing rings 9 are provided on both sides of the upper bearing bush cover 6. The sealing rings 9 are fixed on the roller shaft 4 through clamps, and the side surface of the sealing ring 9 is closely attached to the side surface of the upper bearing bush cover 6. The sealing rings 9 prevent the contact position between the roller shaft 4 and the bearing bush 5 from being exposed to the outside, playing a role in waterproofing and dustproofing.
[0024] Preferably, the upper part of the sealing ring 9 is 20 mm to 50 mm higher than the arc-shaped notch of the rubber plate 7, so that the sealing ring 9 and the rubber plate 7 are staggered with each other, avoiding the cane juice dripping from the rubber plate 7 into the space between the sealing ring 9 and the upper cover 6 of the bearing shell after being poured onto the rubber plate 7, and improving the waterproof effect.
[0025] In a specific embodiment, as Figure 2 shown, an iron weight 10 is provided on the upper part of the rubber plate 7. The iron weight 10 is connected to the frame 1 by bolts, and the iron weight 10 presses the rubber plate 7 tightly on the frame 1. The iron weight 10 makes the rubber plate 7 flat and firmly fixed on the frame 1, blocking the cane juice flowing down from the top roller and ensuring good lubrication of the roller shaft 4 and the bearing shell 5.
[0026] Specifically, as Figure 1 shown, a juice baffle ring 11 is provided on the side of the squeezing roller 3. The middle part of the juice baffle ring 11 is installed on the side of the squeezing roller 3, and the outer periphery of the juice baffle ring 11 extends outward to block outside the lotus root tube hole 8. The juice baffle ring 11 is closer to the lotus root tube hole 8. After the small-flow cane juice is blocked by the juice baffle ring 11, it will flow along the squeezing roller 3 into the squeezing machine, avoiding waste of cane juice.
[0027] Preferably, a groove is provided on the roller shaft 4, and the bearing shell 5 is located in the groove, so that the connection between the bearing shell 5 and the roller shaft 4 is reliable and the axial movement of the roller shaft 4 on the bearing shell 5 is prevented.
[0028] Certainly, the present utility model can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative labor belong to the scope protected by the present utility model.
