Description

Technical Field

[0001] This utility model belongs to the field of tire manufacturing technology, and in particular relates to an automatic tire detection and centering device. Background Technology

[0002] Tires are ring-shaped rubber products used on various vehicles or machinery. Tire production typically involves the following processes: mixing, rubber component preparation, extrusion, calendering, bead forming, cord cutting, attaching triangular rubber strips, belt layer forming, tire forming, vulcanization, final inspection, and tire testing. During this production process, tires are randomly placed on the production line, necessitating alignment equipment to ensure they are arranged systematically along the line for easier subsequent processing.

[0003] Most tire alignment devices currently consist of two independent symmetrical mechanisms, with a cylinder on each side. During tire alignment, the cylinders on both sides simultaneously push the pusher head to position the tire via a linkage mechanism. The disadvantage of this structure is that if the synchronization of the left and right cylinders is poor, and there is a minor malfunction in one of the mechanisms, synchronization becomes even more difficult to guarantee, resulting in inconsistent tire positions each time, or poor repeatability.

[0004] Chinese utility model patent application number 200820218313.4 discloses a tire centering mechanism. This mechanism includes a power push-pull rod, with two connecting rods hinged to its outer end, each with its own center line symmetrical about the rod's linear running track. Two tire lever arms are also hinged to the connecting rods. The lever fulcrum of each tire lever arm is symmetrically positioned along the rod's linear running track. This tire centering mechanism uses two symmetrical connecting rods to drive two tire lever arms, each with one end connected to a pivot. These two tire lever arms push the tire towards the center line from the left and right sides. However, this pushing only considers left and right, not forward and backward. Even when the tire has already shifted forward, the angle between the two tire lever arms continues to increase, causing the tire to move further forward. Therefore, true centering cannot be achieved. Utility Model Content

[0006] To achieve the above objectives, this utility model employs the following technical solution:

The top of the right vertical shaft is connected to the right guard plate, and the bottom of the right vertical shaft is connected to the right connecting sleeve. The left and right connecting sleeves are respectively connected to both ends of the synchronous connecting rod.

[0008] Furthermore, the barrier structure includes an arc-shaped frame, a cover plate, and sliding rollers. The outer side of the arc-shaped frame is provided with a cover plate, and several sliding rollers are distributed along the arc of the arc-shaped frame on the inner side of the cover plate.

[0009] Furthermore, the left connecting sleeve and the right connecting sleeve are circular annular sleeves with keyways in their inner holes; one sleeve has a synchronizing arm on its outer periphery, and the other sleeve has a combination of a synchronizing arm and a driving arm on its outer periphery.

[0010] Furthermore, the left and right vertical shafts are connected to the machine frame via bearing seats, and a protective cover is provided on the outside of the bearing seats.

[0011] Furthermore, the bottom of the stainless steel mesh belt is connected to a silent idler roller, and both ends of the silent idler roller are connected to the mesh belt guide frame through bearing seats.

[0012] Furthermore, the surface of the silent idler roller is lined with a 10-15mm polyurethane rubber layer.

[0013] Furthermore, the mounting position of the silent idler roller on the mesh belt guide frame is adjustable vertically.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The symmetrical clamping structure provides a certain amount of resistance during tire alignment, improving alignment stability and maintaining a stable alignment effect during continuous production.

[0016] This utility model device uses only one cylinder to drive the synchronous connecting rod, thereby enhancing the synchronicity of the centering action, ensuring stable centering effect, and achieving the goal of meeting subsequent production requirements. Attached Figure Description
