Description

Technical Field

[0001] The invention relates to the technical field of tire molding, and in particular to a tire sidewall material detection device and a tire molding machine. Background Art

[0002] With the increasing demand for tires in my country, semi-steel one-step forming machines are gaining more and more attention. Semi-steel one-step forming machines need to perform material detection during the sidewall conveying process. For tires of different specifications, the sidewall width and sidewall spacing are different.

[0003] In the prior art, a small roller with a width of 15 mm is generally used to detect the presence of material on the sidewall. Due to the different sidewall widths and sidewall spacings, it is necessary to manually adjust the position of the small roller to adapt to the sidewall width and sidewall spacing, thereby achieving the purpose of material detection. However, manual adjustment is time-consuming and labor-intensive, which greatly reduces work efficiency.

[0004] Therefore, how to provide a sidewall material detection device that can simultaneously solve the problem of sidewall material detection for tires of different specifications, thereby effectively improving the work efficiency of material detection, is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a sidewall material detection device that can simultaneously solve the problem of sidewall material detection for tires of different specifications, thereby effectively improving the work efficiency of material detection.

[0006] Another object of the present invention is to provide a tire building machine.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A device for detecting material on a tire sidewall, comprising:

[0009] A roller for contacting the tire sidewall, wherein the length of the roller can adapt to the tire sidewalls of different specifications;

[0010] Rotating arms are respectively arranged at both ends of the roller, and the rotating arms are rotatably arranged on the supporting frame;

[0011] An elastic member for connecting the rotating arm and the supporting frame;

[0012] A photoelectric switch is used to detect the position of the rotating arm.

[0013] Preferably, the rotating arm and the supporting frame are connected via a rotating shaft.

[0014] Preferably, the elastic member is a spring, and one end of the spring is connected to the rotating arm, and the other end of the spring is connected to the supporting frame.

[0015] Preferably, the top end surface of the support frame is also provided with a mounting plate for mounting the photoelectric switch.

[0016] Preferably, the photoelectric switch is bolted to the mounting plate.

[0017] Preferably, a connecting plate is further provided on the support frame, and bolts for connecting to the tire building machine are provided on the connecting plate.

[0018] Preferably, the length of the roller is not less than 450 mm.

[0019] A tire building machine comprises the tire sidewall material detection device as described in any one of the above items.

[0020] Preferably, there are two material presence detection devices, which are respectively arranged on the frame of the tire building machine.

[0021] Preferably, the distance between the two material detection devices is 190 mm-210 mm.

[0022] It can be seen from the above technical scheme that the sidewall material detection device disclosed in the present invention includes: a roller for contacting the tire sidewall, and the length of the roller can adapt to the tire sidewalls of different specifications; rotating arms respectively arranged at both ends of the roller, and the rotating arms can be rotatably arranged on the support frame; an elastic member for connecting the rotating arm and the support frame; a photoelectric switch for detecting the position of the rotating arm. When there is no tire sidewall passing under the roller, the roller and the rotating arm are in the initial state, the rotating arm blocks the photoelectric switch, and the photoelectric switch sends a no-material signal; when the tire sidewall passes under the roller, the sidewall and the roller contact, and the roller is lifted upward under the action of the thickness of the sidewall, that is, the roller drives the rotating arm to rotate relative to the support frame, when the rotating arm deviates from the photoelectric switch, the photoelectric switch sends a material signal, and when the sidewall passes, the rotating arm and the roller return to the initial state under the action of the elastic member. Since the length of the roller can adapt to the needs of different specifications of the sidewall, when the sidewall width and the sidewall spacing change, there is no need to adjust the position of the roller. Therefore, the sidewall material detection device can simultaneously solve the problem of sidewall material detection for tires of different specifications, thereby effectively improving the work efficiency of material detection.
