Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figure 1 - Figure 5As shown, a cord calendering device for producing aircraft tires with a protective structure comprises a device body 1 and a roller shaft 20; a protective mechanism is arranged on the roller shaft 20, the protective mechanism comprises a support block 23, the roller shaft 20 and the support block 23 are rotatably connected, the bottom end of the support block 23 is inserted in a fixed plate 24, the support block 23 and the inner wall of the fixed plate 24 are in contact, the bottom end of the fixed plate 24 is welded and fixed on the inner wall of a movable groove 21, the movable groove 21 is provided on the left and right sides of the device body 1, the movable groove 21 is rectangular in design, a support spring 22 is welded and fixed on the bottom end of the support block 23, the bottom end of the support spring 22 is welded and fixed on the inner wall of the movable groove 21, a through groove 39 is provided on the inner wall of the movable groove 21, and a fixing mechanism is arranged on the support block 23;

[0024] A four-axis calender with controllable pressure in the prior art. When new curtain cloth raw materials are re-loaded, the curtain cloth needs to be passed through the bottom roller first. This operation is generally completed manually, and there is no protective mechanism on the roller, which makes it easy for the operator's hands to be pinched by the roller during the manual loading process. During operation, the structural design of the protective mechanism realizes the function of the roller shaft 20 being able to move within the range of the through groove 39, so that during the manual loading of the curtain cloth, the distance between the rollers can be adjusted to avoid the hands being pinched. When the curtain cloth raw materials are to be loaded, the fixing mechanism is first released. At this time, the roller shaft 20 can move downward a certain distance, and the support spring 22 fixed on the bottom end of the support block 23 will be compressed, and the support block 23 will slide into the fixed plate 24, thereby adjusting the distance between adjacent rollers, so that the operator can better load the materials, wherein the support block 23 is in contact with the inner wall of the fixed plate 24 to ensure that the support block 23 will not deviate when moving.

[0025] Furthermore, the fixing mechanism includes a fixing groove 38, which is provided on the support block 23, a fixing column 29 is inserted inside the fixing groove 38, the fixing column 29 is welded and fixed on the disc 33, a protrusion 30 is welded and fixed on the disc 33, the protrusion 30 is rotatably connected to the fixing screw 28, and the fixing screw 28 is threadedly connected to the sleeve 34;

[0026] During operation, the structural design of the fixing mechanism realizes the function of fixing the position of the support block 23, so as to ensure that the roller shaft 20 does not move downward during operation, so as to ensure the stability of the roller shaft 20. When the position of the support block 23 is to be fixed, firstly, by rotating the fixing screw 28, the disc 33 is gradually approached to the support block 23 until the fixing column 29 fixed on the disc 33 is inserted into the interior of the fixing groove 38. At this time, the support block 23 can be fixed by the engagement of the through groove 39 and the inner wall of the fixing groove 38 to prevent the support block 23 from moving downward during operation.

[0027] Further, the casing 34 is fixed to the device main body 1 by screws. An extension post 36 is welded and fixed to the inner wall of the casing 34, and the extension post 36 is threadedly connected to the fixing screw 28;

[0028] During operation, the casing 34 is fixed to the device main body 1 by screws on both sides, which is also convenient for installation and disassembly. The fixing groove 38 can also provide protection for the support block 23 and the fixing plate 24 to ensure that they are not interfered by the outside world. The extension post 36 is used to extend the threaded connection between the fixing screw 28 and the casing 34.

[0029] Further, a rotating block 32 is welded and fixed to the fixing screw 28. The rotating block 32 is rotatably connected to the inside of the rotating groove 31. The rotating groove 31 is opened on the convex block 30, and the rotating block 32 is designed in a T shape;

[0030] During operation, through the rotation of the rotating block 32 inside the rotating groove 31, the rotational connection between the fixing screw 28 and the disc 33 is realized, so that during the process of rotating the fixing screw 28, the disc 33 can be prevented from rotating through the rotation of the rotating block 32, and the diameter of the convex block 30 is smaller than that of the extension post 36 to ensure that the convex block 30 can pass through the extension post 36 normally.

[0031] Further, pulleys 25 are welded and fixed to the front and rear sides of the support block 23. The pulleys 25 are slidably connected to the inside of the sliding groove 26. The sliding groove 26 is opened on the inner wall of the movable groove 21, and a notch 27 is opened on the support block 23;

[0032] During operation, during the downward movement of the support block 23, the pulleys 25 fixed on both sides of the support block 23 will also slide in the sliding groove 26, so that the support block 23 can be more stable during the movement.

[0033] Further, four groups of fixing posts 29 are provided. The four groups of fixing posts 29 are evenly distributed in a circumferential array on the disc 33;

[0034] During operation, the four groups of fixing posts 29 are circumferentially distributed on the disc 33 to improve the fixing effect of the disc 33 on the support block 23 and make the support block 23 more stable.

[0035] Working principle: In the prior art, a pressure-controlled four-axis calender has a new cord material that needs to be passed through the bottom roller before re-loading. This operation is usually done manually, and there is no protective mechanism on the roller, so that the operator's hands are easily pinched by the roller during manual loading. In this case, a cord calendering device for aircraft tire production with a protective structure realizes the function of moving the roller shaft 20 within the range of the through groove 39 through the structural design of the protective mechanism, so that the cord calendering device can be manually adjusted to the desired position. During the process of feeding the cloth, the distance between the rollers is adjusted to avoid pinching the hands. When the curtain cloth material is to be fed, the fixing mechanism is first released. At this time, the roller shaft 20 can move downward a certain distance, and the support spring 22 fixed on the bottom end of the support block 23 will be compressed, and the support block 23 will slide into the fixed plate 24, thereby adjusting the distance between adjacent rollers so that the operator can better feed the material, wherein the support block 23 is in contact with the inner wall of the fixed plate 24 to ensure that the support block 23 will not shift during movement.

[0036] The above description is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents.
