Description

Technical Field

[0001] The utility model relates to the technical field of rubber production equipment, in particular to a two-roller transmission mechanism for a rubber calender. Background Art

[0002] The calender is a machine that presses rubber into a film with a certain thickness. According to the number of calender rollers, it can be generally divided into two-roller, three-roller, four-roller and five-roller calenders. The two-roller calender of the prior art includes a frame, and the two sides of the frame are provided with mounting grooves that run through the two sides. The two calender rollers are provided with bearing seats at both ends, and the bearing seats are located in the mounting grooves. The bearing seats at both ends of one of the calender rollers are slidably connected with the mounting grooves, so that the gap between the two calender rollers can be adjusted, and then the thickness of the film can be adjusted. In order to ensure the pressing effect, the rotation speeds of the two calender rollers should be as similar as possible and rotate in opposite clockwise directions. The two-roller calender of the prior art is provided with a motor at the end of each of the two calender rollers. When adjusting the position of a calender roller, the motor at its end also moves with it, so as to facilitate the adjustment of the position of the calender roller. However, in this way, when starting and running, the rotation speeds of the two motors are sometimes inevitably different, resulting in a certain difference in the rotation speeds of the two calender rollers, which affects the pressing effect. The present application provides a two-roller transmission mechanism for a rubber calender, so that when the gap between the two calender rollers can be adjusted, only one calender roller needs to be connected to the motor for transmission so that the two calender rollers can rotate at the same speed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0011] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0012] Detailed implementation method: Combine Figure 1-2As shown in the figure, a two-roll drive mechanism for a rubber calender includes a frame 1 with mounting grooves 2 provided on both sides. It also includes a first calender roll 5 and a second calender roll 6, and first bearing seats 3 and second bearing seats 4 are respectively provided at the ends of the two. The first bearing seat 3 and the second bearing seat 4 are located in the mounting groove 2, and the first bearing seat 3 is slidably connected to the mounting groove 2. One end of the first calender roll 5 is provided with a first bevel gear 51, and one end of the second calender roll 6 is provided with a second bevel gear 61. On the sides of the first bearing seat 3 and the second bearing seat 4 close to each other, a first support plate 31 and a second support plate 41 are respectively provided. The extending directions of the first support plate 31 and the second support plate 41 are parallel to the axis of the calender roll. A first rotating shaft 71 is rotatably connected to the first support plate 31, and a second rotating shaft is rotatably connected to the second support plate 41. A third bevel gear 7 meshing with the first bevel gear 51 is provided on the first rotating shaft 71, and a fourth bevel gear 8 meshing with the second bevel gear 61 is provided on the second rotating shaft. The first rotating shaft 71 is slidably connected to the second rotating shaft. When the second rotating shaft rotates, it can drive the first rotating shaft 71 to rotate synchronously. The tooth number ratio of the first bevel gear 51 to the third bevel gear 7 is equal to the tooth number ratio of the second bevel gear 61 to the fourth bevel gear 8. For the convenience of manufacturing and maintenance, it is preferred that the first bevel gear 51 and the second bevel gear 61 have the same specifications, and the third bevel gear 7 and the fourth bevel gear 8 have the same specifications.

[0013] The specific way of the sliding connection between the first rotating shaft 71 and the second rotating shaft is as follows: One end of the second rotating shaft away from the fourth bevel gear 8 is provided with a shaft cylinder 81, and the first rotating shaft 71 is inserted into the shaft cylinder 81 and the two are slidably connected.

[0014] The specific way of the sliding connection between the first rotating shaft 71 and the shaft cylinder 81 is as follows: On both sides of one end of the first rotating shaft 71 away from the third bevel gear 7, first key grooves are provided. The first key grooves do not penetrate the end of the first rotating shaft 71. A flat key is provided in the first key grooves. On both sides inside the shaft cylinder 81, second key grooves are provided. The second key grooves penetrate one end of the shaft cylinder 81 away from the fourth bevel gear 8, and the flat key is inserted into the second key grooves. Of course, a regular hexagonal prism can also be provided at one end of the first rotating shaft 71, and a groove with a regular hexagonal cross-section is provided inside the shaft cylinder 81, and the regular hexagonal prism is slidably connected to the groove.

[0015] During use, in combination with Figure 1As shown in the figure, when adjusting the position of the first calender roll 5, there is sliding between the first rotating shaft 71 and the second rotating shaft during sliding, but the two never separate, enabling them to rotate synchronously. After the second calender roll 6 is connected to the motor for transmission, when the motor rotates, it drives the second calender roll 6 to rotate. The second bevel gear 61 drives the fourth bevel gear 8 and the third bevel gear 7 to rotate. The third bevel gear 7 drives the first bevel gear 51 to rotate at the same speed as the second bevel gear 61, and the first bevel gear 51 rotates in the opposite clockwise direction to the second bevel gear 61, so that the first calender roll 5 and the second calender roll 6 rotate at the same speed and in opposite clockwise directions.
