[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1 to Figure 3 As shown, a film laminating front guiding mechanism is installed on the conveyor belt structure 10 through the side plates 11 arranged on both sides of the conveyor belt structure 10. The guiding mechanism includes two guiding plates 20 arranged at intervals and extending along the film conveying direction. A material passage 201 for the film to pass through is formed between the two guiding plates 20. The guiding mechanism also includes a flapping cylinder 30 installed between the two side plates 11 and a scissor structure arranged on the top of the two guiding plates 20. The scissor structure includes two The middle part of the two swing arms 40 is hingedly matched by a pin 50, and the ends of the two swing arms 40 on the same side are hingedly matched on the same guide plate 20 at intervals, and the end of the piston rod of the snapping cylinder 30 is hingedly matched with the pin 50; when the film is conveyed to the feed channel 201, the piston rod of the snapping cylinder 30 extends out and actuates the pin 50 to drive the two swing arms 40 to rotate, control the two guide plates 20 to move towards each other, and the guide plates 20 tap the opposite sides of the film to guide the film to the preset conveying path.

[0033] The structures of the various components of the utility model are described below.

[0034] like Figure 1 As shown, both ends of the guide plate 20 in the length direction are provided with guide angles 21 for the ends of the film to slide away. With such a design, when the film is conveyed to contact the guide angles 21, the ends of the film can be deflected along the guide angles 21 to continue to be conveyed between the two guide plates 20, which is convenient for subsequent correction and avoids film blockage.

[0035] like Figure 1 to Figure 3As shown, two guide rods 111 located above the conveyor belt structure 10 are fixedly connected between the two side plates 11 at intervals, and a guide hole 22 for the guide rod 111 to slide through is opened on the center guide plate 20, and a linear bearing that slides through the guide rod 111 is installed in the guide hole 22; through the setting of the guide rod 111, the two center guide plates 20 can slide toward or away from each other in a sliding path perpendicular to the preset conveying direction, thereby improving the stability of the sliding process of the center guide plate 20.

[0036] like Figure 1 to Figure 4 As shown, a mounting platform 60 located above the guide plate 20 is installed between the two side plates 11, and the flapping cylinder 30 is fixed on the mounting platform 60. A sliding column 62 extending along the conveying direction is vertically fixed on the assembly plate 61 at the front end of the mounting platform 60. The pin shaft 50 has a hinged portion 51 hingedly matched with the rocker arm 40 and a connecting portion 52 fixed on the top of the hinged portion 51. The top of the connecting portion 52 is fixedly connected to the end of the piston rod of the flapping cylinder 30. A sliding hole 521 is opened on the connecting portion 52 for the sliding column 62 to slide through, and a linear bearing for the sliding column 62 to slide in is installed in the sliding hole 521.

[0037] Since there is an installation error between the positions of the conveyor belt structure 10 and the forming drum 80, the preset conveying path of the film must be adjusted left and right before production. Moreover, when the tire changes the production process or changes the position of the forming drum 80, the fitting position of the film will change. At this time, the preset conveying path of the film also needs to be adjusted left and right.

[0038] To solve the above problems, Figure 1 to Figure 3 As shown, a screw rod 70 is rotatably installed between the two side plates 11, a screw nut 601 threadably matched with the screw rod 70 is provided on the mounting platform 60, and an operating handle 71 is fixedly installed on one end of the screw rod 70 extending out of the side plate 11; an adjusting rod 112 is fixedly installed between the two side plates 11, and an adjusting hole 602 is provided on the mounting platform 60 for the adjusting rod 112 to slide through; sliding buckle strips 63 are fixedly installed at both ends of the assembly plate 61 in the length direction, and the two guide plates 20 are located between the two sliding buckle strips 63, and the sliding buckle strip 63 is provided with a sliding buckle hole 631 for the guide rod 111 to slide through, and linear bearings are installed in the adjusting hole 602 and the sliding buckle hole 631.

[0039] When the left-right error of the fitting position of the film relative to the forming drum 80 is large, the operating handle 71 is turned, the screw 70 is rotated and cooperates with the screw nut 601 on the mounting platform 60 to drive the snapping cylinder 30 and the guide plate 20 to slide as a whole in a direction perpendicular to the film conveying path until the transfer channel 201 between the two guide plates 20 is adjusted to the relative position with the forming drum 80 (that is, the transfer channel 201 is relative to the preset conveying path of the film).

[0040] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
