Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slip rings, in particular to a large-torque slip shaft. Background Technique
[0002] Slip shafts are mainly divided into two methods: central air pressure and side pressure. No matter which method, they all have the function of slip ring slipping. The slipping function means that multiple rolls of materials are wound on one shaft at the same time. Because the thickness of the materials is uneven, some coils are loose and some coils are tight. The tight ones will slip to eliminate the tension and achieve an ideal winding effect. The slip shaft will adjust the size of the air pressure to adjust the size of the tension, so that the whole shaft is at a stable value. However, most of the existing slip shafts have small torque, use a single-channel air source control, have poor control accuracy, single function, and it is difficult to control the actual use quality, reducing the practicability of the slip shaft.

When inflated, the gas will push out the black rubber ring. Since the black rubber ring presses the slip ring, under the action of the gas, the black rubber ring presses the slip ring and pushes out the slip sheet.

[0025] A through hole 2 is provided inside the slip shaft body 1, and the shape and size of the through hole 2 are both mutually matched with the shape and size of the slip sheet 5. The slip sheet 5 is movably connected to the slip shaft body 1 through the through hole 2. The movable connection between the slip sheet 5 and the slip shaft body 1 facilitates the ejection of the slip sheet 5 when the slip ring 3 is pressed down. The shape and size of the slope 4 are both mutually matched with the shape and size of the slip sheet 5. The slip sheet 5 is slidably connected to the slip ring 3 through the slope 4. The slip sheet 5 is inclined and its shape and size correspond to that of the slope 4, so that the slip sheet 5 can be ejected when the slip ring 3 is pressed down. An installation groove 8 is provided inside the cover 6, and the shape and size of the installation groove 8 are both mutually matched with the shape and size of the black rubber ring 9. The black rubber ring 9 is movably connected to the cover 6. The black rubber ring 9 is installed in the installation groove 8 and presses the slip ring 3 tightly. A reset hole 12 is provided on one side of the slip ring 3, and a reset spring is arranged inside each reset hole 12. Through the reset spring, the slip ring 3 can be reset after the inflation is completed, which is safe and reliable. The number of the through hole 2, the slope 4, the slip sheet 5 and the reset hole 12 is six. The number, shape and size of the through hole 2, the slope 4 and the slip sheet 5 correspond to each other. A reset spring is arranged inside the reset hole 12, so that the slip ring 3 can be reset. One side of the black rubber ring 9 presses the slip ring 3 tightly, and the position of the black rubber ring 9 corresponds to the air passage hole 7. When the black rubber ring 9 is inflated, the gas will eject the black rubber ring 9. Since the black rubber ring 9 presses the slip ring 3 tightly, under the action of the gas, the black rubber ring 9 presses the slip ring 3 tightly and ejects the slip sheet 5.
[0026] Working principle: The slip shaft has two air passages. When the slip ring 3 is pressed down, the slip ring 3 moves downward. Correspondingly, the slip sheet 5 will move upward, thus achieving the effect of ejection. The way for the slip ring 3 to achieve downward pressure is through inflation. One side of the slip ring 3 is connected to a cover 6. An air passage hole 7 is provided inside the cover 6. An installation groove 8 is provided inside the cover 6, and there is a black rubber ring 9 inside the installation groove 8. When inflated, the gas ejects the black rubber ring 9 through the air passage hole 7. Since the black rubber ring 9 presses the slip sheet 5 tightly, the inflated black rubber ring 9 presses the slip ring 3 tightly and ejects the slip sheet 5 after inflation. A number of rubber plugs 11 are provided inside the shaft sleeve 10. The rubber plugs 11 will eject after inflation and press against the slip ring 3. After the inflation is completed, since there are six air passage holes 7 provided on one side of the slip ring 3 and reset springs are arranged in all the six air passage holes 7, the slip sheet 5 returns to its original position relying on the reset spring.
[0027] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art to which the present invention pertains.
