[0025] The rack comprises a base (11) and a support plate (12), and the support plate (12) is hinged to the base (11).

[0026] The conveying mechanism comprises a plurality of first rollers (21) and second rollers (22), the rollers are installed side by side on the support plate (12), the first rollers (21) are arranged in the centering area, and the second rollers (22) are arranged in the weighing area. Among them, the first roller (21) is a universal ball roller, that is, a universal ball is arranged on the roller rod, which can not only move the tire blank 10 forward, but also move the tire blank 10 left and right.

[0027] The eight-shaped centering mechanism comprises two groups of centering assemblies, which are symmetrically installed on both sides of the base (11) and connected through connecting rods. The centering assembly comprises a centering swing arm (31) and a centering cylinder (32), the centering swing arm (31) is located above the first roller (21), and the centering cylinder (32) is connected with the centering swing arm (31) through a connecting piece. A plurality of vertical and parallel arranged rollers (311) are arranged on the centering swing arm (31), which can reduce the friction between the centering swing arm (31) and the tire blank 10.

[0028] The weighing mechanism comprises a weighing assembly (41) and a jacking cylinder assembly (42), the weighing assembly (41) is arranged above the second roller (22), and the jacking cylinder assembly (42) is arranged at the middle position of the bottom end of the support plate (12). The weighing assembly (41) comprises a scale (412) and a plurality of tire blank supporting members (411), the tire blank supporting members (411) are arranged side by side on the top of the scale (412), and the tire blank supporting members (411) can pass through the gap between the second rollers (22).

[0029] The weighing conveying device is wirelessly connected with a PLC cabinet, and the weighing conveying device can be intelligently controlled.

[0030] The working principle of the tire blank weighing conveying device is as follows:

[0031] In the part not shown in the figure, the device is further provided with a transition frame and a tire turning net chain conveying device, the transition frame is respectively connected with the tire unloader and the tire turning net chain conveying device at two ends, the weighing conveying device is arranged at the outlet end of the tire turning net chain conveying device, and the hoist preparation area is arranged at the outlet end of the weighing conveying device. Therefore, the transition frame, the tire turning net chain conveying device, the weighing conveying device and the hoist preparation area form a tire blank 10 centering, weighing and transporting assembly line.

[0032] In the assembly line, the tire unloader pushes the tire blank 10 onto the transition frame, the tire blank 10 rolls along the transition frame to the tire turning net chain conveying device, the tire turning net chain conveying device turns the tire blank 10 in the vertical state into the horizontal state, and then the tire blank 10 is conveyed to the weighing conveying device.

[0033] The tire blank 10 first enters the centering area. The first roller (21) gives the tire blank 10 a forward running force, when the tire blank 10 is just located in the centering area, the tire blank 10 can smoothly push away the centering swing arms (31) on both sides to enter the weighing area; when the tire blank 10 is offset, the centering swing arms (31) will form a resistance to the tire blank 10 to intercept the tire blank 10, and the resistance is also a pushing force to the tire blank 10, and the first roller (21) is a universal ball roller, so that the tire blank 10 can move to the middle under the external force, thereby entering the centering area. When the tire blank 10 is located in the centering area, it can only touch the centering swing arm (31) on one side, at this time, the centering swing arm (31) on the other side will also be opened under the action of the connecting rod.

[0034] When the tire blank 10 enters the weighing area and reaches above the weighing assembly (41), the photoelectric sensor is triggered, under the control of the PLC system, the first roller (21) and the second roller (22) stop running, the piston rod of the jacking cylinder assembly (42) is retracted, the end of the support plate (12) slowly falls towards the ground, the tire blank 10 stably falls onto the tire blank support (411), at this time the scale (412) starts to weigh. After the weighing is completed, the PLC system records the data, the piston rod of the jacking cylinder assembly (42) is extended, the end of the support plate (12) is lifted upwards, the first roller (21) and the second roller (22) resume running, and the tire blank 10 enters the elevator preparation area.

[0035] When the first roller (21) and the second roller (22) stop running, the delivery of the rear tire blank 10 is also stopped, so as to avoid the weighing interference of the rear tire blank 10 on the weighing area and the stacking of the tire blank 10.

[0036] The above is the description of the embodiments of the present application, through the above description of the disclosed embodiments, the person skilled in the art can realize or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
