Abstract
Description
Technical Field
[0001] The utility model belongs to the field of tire production, and in particular relates to a monitoring and limiting mechanism for a pressure roller of a calender. Background Art
[0002] Steel cord is the skeleton material of radial tires. The quality of the cord directly affects the service life of the tire, so the quality consistency control of steel cord is very critical. The cord includes the film and the cord in the film, and the cord is located in the middle of the film. During production, it is necessary to glue both sides, first paste the lower film, and then paste the upper film.
[0003] When pasting the lower film, a calender is used, and a pressure roller and a calender 3# roller are set on the calender. There are grooves evenly distributed on the surface of the pressure roller, and the steel cord is arranged in the grooves, half of which is located in the grooves and the other half is exposed. When pasting the glue, the calender 3# roller is wrapped with a film, close to the pressure roller, and rotates. The leaked part of the steel cord enters the film, and half of the glue pasting is completed. In this process, it is necessary to keep the distance between the pressure roller and the calender 3# roller stable, ensure that the position of the steel cord entering the film is consistent, and ensure the balance of the cord. If the distance between the two rollers is small, the cord enters the lower film too deeply, and the lower film of the finished cord is thin, affecting the quality of the cord; if it is too small, the pressure roller will squeeze the lower film, causing the film to be separated from the calender 3# roller, forming bubbles; in severe cases, the lower film will wrap the pressure roller, causing the cord to be exposed and scrapped. Therefore, it is necessary to set a minimum gap during the production process to limit the spacing between the two rollers and monitor it in real time during the production process.
[0004] When producing cord fabrics of different specifications, the cord diameter and film thickness are different, the gap between the two rollers is different, and the minimum spacing also needs to be adjusted according to the specifications. When adjusting, it is necessary to ensure that the gap between the pressure roller and the calender 3# roller is equal, that is, the position where the cord enters the film is consistent.

[0016] like Figure 1-2 As shown, a calender pressure roller monitoring and limiting device includes a calender 3# roller 5 and a pressure roller 4, wherein both sides of the pressure roller 4 are respectively hinged to one end of a rotating arm 2, and the rotating arm 2 rotates around a rotating shaft 21; an elastic mechanism is arranged below the other end of the rotating arm 2, and a limiting plate 3 is arranged above, and a limiting device and a distance measuring device are arranged between the limiting plate 3 and the rotating arm 2.
[0017] The adjusting device rotates the rotating arm 2 by adjusting the distance between the limit plate 3 and one end of the rotating arm 2, thereby adjusting the position of the pressure roller 4, and then adjusting the distance between the pressure roller 4 and the calender 3# roller 5; the distance measuring device is used to detect the change in the distance between the limit plate 3 and the rotating arm 2.
[0018] The described calender pressure roller monitoring limit device comprises a screw rod 1, wherein the screw rod 1 passes through a limit plate 3, and the lower end of the screw rod 1 abuts against the upper edge of a rotating arm 2, and can move up and down along the wire hole in the limit plate 3; the described elastic mechanism comprises an oil cylinder 8, one end of the oil cylinder 8 is hinged to the lower edge of the rotating arm 2, and the other end is hinged to the calender; the screw rod 1 cooperates with the oil cylinder 8 to adjust the position of the pressure roller 4 by adjusting the angle of the rotating arm 2, and the screw rod 1 limits the distance between the calender 3# roller 5 and the pressure roller 4 by limiting the rotating arm 2.
[0019] The described calender pressure roller monitoring and limiting device, the distance measuring mechanism includes a linear displacement sensor 6, the linear displacement sensor 6 is fixed to the outer side of one end of the rotating arm 2, the linear displacement sensor 6 extends a measuring rod 61 upward, and the upper end of the measuring rod 61 abuts the limiting plate 3; when the rotating arm 2 rotates, the extended length of the measuring rod 61 changes; the two linear displacement sensors 6 are connected to a dual-channel display screen 7, and the dual-channel display screen 7 can simultaneously display the length changes of the measuring rods 61 on both sides. The linear displacement sensor 6 converts the displacement of the measuring rod 61 into an electrical signal, and then transmits the electrical signal to the dual-channel display screen 7, which is a prior art. In actual production, the movement of the pressure roller and the rotation of the rotating arm are relatively subtle. Through the linear displacement sensor 6 and the dual-channel display screen 7, the distance change between the rotating arm and the limiting plate can be intuitively and accurately seen, thereby knowing the unknown state of the pressure roller.
[0020] The use process of the utility model is as follows;
[0021] First, determine the standard reading of the dual-channel display required for the production of this batch of products. Before production begins, the oil cylinder 8 is fully extended, and the rotating arm 2 is pushed to the zero position. At the zero position, the readings of the dual-channel display 7 are all 0, and the axis of the pressure roller 4 and the calender 3# roller 5 are on the same horizontal plane. At this time, the distance between the two rollers is the shortest. Figure 1 As shown. During production, the cord and film enter the roller space from below the two rollers, and the position of the calender 3# roller 5 is fixed. The cord and film exert force on the pressure roller 4, so that the pressure roller 4 moves away from the calender 3# roller 5, and the rotating arm 2 rotates counterclockwise. The distance between the limit plate 3 and the rotating arm increases, and the measuring rod of the linear displacement sensor 6 extends and becomes longer. The indication on the dual-channel display screen changes. At this time, the production has not entered a stable state, and the indication fluctuates within a certain range. After the indication gradually stabilizes, adjust the screw rod 1 to extend the screw rod 1. At this time, the rotating arm rotates counterclockwise, and the indication on the dual-channel display screen increases. When it increases to the standard reading of this production, the limit device is set. Due to the existence of the screw rod 1, there is an extreme position when the rotating arm rotates clockwise, that is, the upper surface of the rotating arm is against the lower surface of the screw rod. At this time, the distance between the pressure roller and the calender 3# roller is the set minimum value. During the production process, the distance between the pressure roller and the calender 3# roller will not be less than this minimum value. By arranging limit devices and adjustment devices at both ends, it can be ensured that the minimum distances at the two ends are equal.
[0022] During the production process, if the film is too thick, the distance between the pressure roller and the calender roller 3# becomes larger, the linear displacement sensor detects the change in the distance between the rotating arm and the limit plate, and the dual-channel display screen reading exceeds the standard reading. The operator can know the change in the distance between the pressure roller and the calender roller 3# through the dual-channel display screen reading, and then notify the upstream film production to reduce the film thickness to ensure that the position where the cord enters the film is the same.
[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
