DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] The positions mentioned in this specification are based on the positions of the wire ring forming mechanism for online apex rubber coating of the utility model during normal operation, and do not limit the positions during storage and transportation. They only represent relative position relationships, not absolute position relationships.

[0021] like Figure 1 and Figure 2 As shown in the figure, a wire ring forming mechanism for online apex rubber coating includes a bottom plate 1 fixed on the forming machine, a forming disc 2 for forming a wire ring 5 and a rotation drive device for driving the forming disc 2 to rotate are rotatably mounted on the bottom plate 1, and the rotation drive device uses a motor (not shown in the figure) to drive the forming disc 2 to rotate. An expansion device is also provided on the forming disc 2, and the expansion device controls the forming disc 2 to expand or contract, thereby clamping or loosening the wire ring 5. The forming technology of the wire ring belongs to the prior art, so the specific structure of the rotation drive device and the expansion device will not be described in detail in this embodiment, and reference can be made to Chinese patent CN208359540U, a tire wire forming disc.

[0022] A pressure roller mechanism 3 is installed on one side of the bottom plate 1 on the forming disc 2; the pressure roller mechanism 3 includes a swing shaft 31 swingably installed on the bottom plate 1, and a pressure roller 32 is rotatably installed on one end of the swing shaft 31. A swing driving device 33 is transmission-connected to the swing shaft 31, and the swing driving device 33 drives the swing shaft 31 to swing, so that the pressure roller 32 presses the apex rubber 4 onto the formed wire ring 5.

[0023] like Figure 1 and Figure 3 As shown together, the swing driving device 33 can control the swing of the swing shaft 31 through a connecting rod mechanism or other structures. In order to ensure high operating accuracy, the swing driving device 33 in this embodiment includes a rotating shaft 331 rotatably mounted on the base plate 1, and the rotating shaft 331 is rotatably mounted on a bearing seat 332, and the bearing seat 332 is fixedly mounted on the base plate 1. In order to achieve stable support, two bearing seats 332 are provided, which are respectively located at both ends of the rotating shaft 331.

[0024] The cylinder 335 is extended and retracted to control the reciprocating sliding of the rack 334 , thereby driving the gear 333 to reciprocate, realizing the reciprocating rotation of the rotating shaft 331 , thereby realizing the swing of the swing shaft 31 .

[0025] like Figure 2 As shown, in order to avoid the idling of the rotating drive device, the rotating direction of the rotating drive device driving the forming disk 2 during the forming process of the wire ring 5 is opposite to the rotating direction of the rotating drive device driving the forming disk 2 during the pasting process of the apex rubber. That is, during the forming process of the wire ring 5, the rotating drive device drives the forming disk 2 to rotate counterclockwise, while during the pasting process of the apex rubber 4, the rotating drive device drives the forming disk 2 to rotate clockwise. ( Figure 2 The directions of the middle arrows are the wire feeding directions of the wire ring 5 and the feeding directions of the apex rubber 4 respectively. In actual applications, the rotation direction of the forming disk 2 can be adjusted as needed to adapt to site requirements.

Therefore, the corresponding feeding ends are provided with a wire conveying device and an apex conveying device, and the wire conveying device and the apex conveying device are provided with a cutting device, so as to realize the cutting of the feeding.

[0029] During the forming process of the wire ring 5, the forming disc 2 is expanded by the expansion device, the steel wire is transported from the wire conveying device to the forming disc 2, and the rotation drive device drives the forming disc 2 to rotate counterclockwise to achieve the forming of the wire ring 5;

[0030] During the pasting process of the apex rubber 4, the apex rubber 4 is transported from the apex rubber conveying device to the forming disk 2, and then the swing driving device 33 drives the pressure roller 32 to press on the wire ring 5 and the apex rubber 4 to achieve compression, and then the rotating driving device drives the forming disk 2 to rotate clockwise to achieve the pasting of the apex rubber 4.
