Description

Technical Field

[0001] The utility model relates to the field of tire production equipment, in particular to a crank-arm type tire shifting device. Background Art

[0002] As we all know, finished tires on the transport line have to go through processes such as hair cutting machines, appearance inspections, averaging machine inspections, and sorting in finished product warehouses. During the transportation of tires on the transport line, tire pusher arms are required to complete the sorting work in each step. The form of the tire pusher arm directly affects the quality of sorting. Different forms of tire pusher arms may result in the tire not being pushed into place and a high failure rate of the tire pusher arm. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a crank-arm type tire shifting device, which increases the service life of the tire shifting arm.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a crank-arm type tire shifting device is provided with a transport line, and is characterized in that an arm frame is hingedly connected to the base of the transport line via a rotating shaft, the arm frame is an L-shaped structure with an opening angle of 150 degrees, the left end of the arm frame is fixed to one end of the L-shaped connecting rod, the other end of the connecting rod is connected to the telescopic rod of the cylinder, the front end face and the rear end face of the upper part of the arm frame are processed with mounting holes, and a free roller is installed between the two mounting holes via fixing screws.

[0005] The utility model has the beneficial effects of convenient replacement of the free roller, reducing the weight of the tire shifting arm, reducing the wear of the bearing, and prolonging the service life of the tire shifting arm. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0007] Figure 1 A schematic structural diagram of the utility model.

[0008] Figure 2 It is a top view of the lever arm frame of the utility model.

[0009] In the figure, 1. free roller, 2. arm frame, 3. rotating shaft, 4. connecting rod, 5. cylinder, 6. transportation line. DETAILED DESCRIPTION

[0010] In the figure, the utility model is provided with a conveyor line 6, on the base of the conveyor line 6, a lever arm frame 2 is hingedly connected via a rotating shaft 3, the lever arm frame 2 is an L-shaped structure with an opening angle of 150 degrees, the left end of the lever arm frame 2 is fixed to one end of an L-shaped connecting rod 4, the other end of the connecting rod 4 is connected to the telescopic rod of a cylinder 5, the lever arm frame 2 is made of channel steel, the front end face and the rear end face of the upper part of the lever arm frame 2 are processed with mounting holes, and a free roller 1 is installed between the two mounting holes via fixing screws.

[0011] The tire is conveyed forward on the conveying line 6. When it reaches the tire pushing position, the cylinder 5 drives the connecting rod 4. The connecting rod 4 drives the arm frame 2 to rotate around the rotating axis 3, thereby contacting the tire. With the help of the 150-degree elevation angle, the smoothness of the tire pushing is increased, so that the tire can smoothly enter the tire outlet of the conveying line 6, and then the cylinder 5 drives the arm frame 2 to retract.

[0012] If the next tire and the previous tire need to enter the same tire outlet, the arm frame 2 does not need to be retracted, and the tire continues to be blocked into the tire outlet by the rotation of the free roller 3.

[0013] The contact part between the arm frame 2 and the tire of the utility model adopts two rows of free rollers. The arm frame 2 is L-shaped with a middle angle of 150 degrees. The free roller 1 is easy to replace, with little damage to the cylinder, supporting points, etc., and a low failure rate.

Claims

1. A crank-type tire shifting device, provided with a transport line, characterized in that: The base of the conveyor line is hinged with an arm frame via a rotating shaft. The arm frame is an L-shaped structure with an opening angle of 150 degrees.
