[0023] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0024] It should also be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0025] The specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 4 As shown, a rubber calender S-shaped cotton yarn device comprises a calender frame 1 and a wire tower 2, wherein the wire tower 2 is arranged on one side of the calender frame 1.

[0027] Among them, Figure 1As shown, the calender frame 1 includes a vertically arranged support seat 7 and a support member 8 arranged on one side of the support seat 7; the support seat 7 is provided with two groups, and the support members 8 on the two groups of support seats 7 are both facing the line tower 2. A guide roller and a moving assembly are arranged on the support member 8, and both ends of the guide roller and the moving assembly are transversely arranged on the support members 8 of the two support seats 7, wherein the moving assembly is arranged below the guide roller. By arranging the support member 8, the guide roller and the moving assembly can be better fixed on the support seat 7.

[0028] like Figure 1 and Figure 4 As shown, the moving component includes a servo motor 3 and a toothed belt electric cylinder 4. The two ends of the toothed belt electric cylinder 4 are fixedly connected to the support members 8 located on both sides thereof, and the servo motor 3 is transmission-connected to the toothed belt electric cylinder 4. By starting the servo motor 3, the toothed belt electric cylinder 4 can be moved left and right.

[0029] A fixedly connected wire guide mounting bracket 5 is arranged above the toothed belt electric cylinder 4. The wire guide mounting bracket 5 is arranged at the front end of the guide roller and has a plurality of evenly distributed wire threading holes 6 on the top end thereof. When the toothed belt electric cylinder 4 is driven to move by the servo motor 3, the wire guide mounting bracket 5 will also move along with the toothed belt electric cylinder 4.

[0030] like Figure 1 As shown, the guide roller is a passive roller and can only rotate passively. The guide roller includes a first guide roller 9 and a second guide roller 10, and the first guide roller 9 and the second guide roller 10 are both mounted on the support members 8 of the two sets of support seats 7, and the first guide roller 9 is installed below the second guide roller 10.

[0031] like Figure 1 to Figure 2 As shown, a moving member 15 is also provided on the support member 8, and the moving member 15 is fixedly arranged below the second guide roller 10. The moving member 15 comprises a housing 151 and a shaft 152, wherein the housing 151 is fixedly connected to the support member 8, and a through hole is arranged inside the housing 151, and the shaft 152 is inserted into the through hole and can move axially along the setting direction of the through hole, and the front end of the shaft 152 protrudes from the housing 151 before or during movement, and the end of the first guide roller 9 is fixedly arranged on the front end of the shaft 152.

[0032] The setting direction of the shaft body 152 on the horizontal plane is perpendicular to the setting direction of the first guide roller 9; by moving the shaft body 152 forward and backward, the first guide roller 9 can also move forward and backward. The moving member 15 capable of moving the first guide roller 9 forward and backward can better fit the cotton yarn on the carcass of the calender.

[0033] The moving member 15 mentioned above can be, but is not limited to, a cylinder.

[0034] like Figure 1 As shown, a plurality of cotton yarn placement layers 21 are provided on the yarn tower 2, and a plurality of evenly distributed fixed shafts 22 are provided on the cotton yarn placement layer 21. By providing the fixed shafts 22, the cotton yarn can be better fixed on the yarn tower 2. The fixed shaft 22 faces the calender frame 1, and an angle is set between the fixed shaft 22 and the calender frame 1, and the angle is 40°-50°. By setting this angle, the cotton yarn can be drawn out better and faster by the device.

[0035] In order to better control the cotton yarn, a threading hole 23 is provided on the top of the turret 2 so that the cotton yarn can be initially positioned.

[0036] like Figure 1 and Figure 3 As shown, the wire guide mounting bracket 5 has a protrusion 61 on the threading hole 6, and a U-shaped fixing piece 62 is clamped on the protrusion 61, and a barb piece 63 is provided on the inner side of the U-shaped fixing piece 62, and the bottom of the barb piece 63 is fixedly connected to the inner side of the U-shaped fixing piece 62, and the top of the barb of the barb piece 63 is arranged toward the inner bottom of the U-shaped fixing piece 62. When the cotton yarn is fixed on the threading hole 6, it can slide in better through the barb piece 63, which reduces the difficulty of threading the cotton yarn and increases the efficiency, and the arrangement of the barb piece 63 can also make it difficult for the cotton yarn to fall off the wire guide mounting bracket 5.

[0037] like Figure 1 As shown, the device is also provided with an operating box 11, which is electrically connected to the servo motor 3. By operating the operating box 11, the toothed belt electric cylinder 4 can adjust its left and right moving distance and speed according to needs, so that the cotton yarn can be attached to the tire body in the form of an S-shaped wave line, thereby increasing the exhaust area, so that the defective rate of the finished tire will not increase due to poor exhaust.

[0038] First, place the cotton yarn ball on the fixed shaft 22 of the bobbin 2, and then pass the thread end of the cotton yarn through the threading hole 23 and the threading hole 6 in turn, and then set it around the first guide roller 9 and the second guide roller 10, and finally fit it on the carcass of the calender; after the cotton yarn is set, the servo motor 3 is controlled by the operating box 11 to operate, and the toothed belt electric cylinder 4 is driven to reciprocate left and right, and the cotton yarn realizes S-shaped fitting under the influence of the toothed belt electric cylinder 4.

[0039] The utility model installs the original mechanical fixed threading hole 6 on a toothed belt electric cylinder 4 driven by a high-precision Siemens servo motor 3, and the threading hole 6 adopts a U-shaped wire guide with an open sliding structure to greatly reduce the threading time and difficulty. The threading hole 6 can be automatically controlled during operation and independently set the lateral reciprocating linear motion required by the process. The lateral motion of the threading hole 6 and the longitudinal motion of the cord product are synthesized to achieve S-shaped cotton yarn attachment. It is equipped with the latest Siemens S7-1500 control system and adopts a high-precision servo motion system. The algorithm reads the running speed of the calender at the cotton yarn in real time, and calculates the lateral reciprocating speed of the threading hole 6 by reading the calender speed, which is used to match the displacement size (S-shaped curve amplitude) and speed (S-shaped curve period) of the lateral movement of the cotton yarn device. The system adopts servo high-precision control, which can meet the position and speed synchronization of the calender production line speed of 60 meters / minute, and realize the dynamic adjustment of the S-shaped curve period width of the cord. It can also manage the formulation of cord products of different specifications and realize one-key switching of the formulation. The function is complete and reliable.
