Description

Technical Field

[0001] This utility model belongs to the field of tool cart technology, specifically relating to a multi-functional I-beam wheel transfer cart for tire manufacturing. Background Technology

[0002] Tire structure is assembled from multiple components such as inner liner, airtight layer, belt layer, bead, sidewall, shoulder, and tread. Among them, the inner liner, airtight layer, sidewall, and tread are all rubber sheet components made of rubber material. When the rubber sheet components are transferred in the workshop, they are usually rolled up using a roll-on (commonly known as a reel) and transported to various assembly stations. In order to prevent the rubber sheet layers from sticking together, an insulating liner is usually placed between the layers during transfer. Moreover, each roll of rubber sheet is usually quite heavy, requiring the use of a transfer trolley for assisted transportation. Traditional transfer trolleys use ordinary forklifts or handcarts, relying on manual labor for transportation and loading / unloading. This is physically demanding for workers, has low transfer efficiency, and incurs high labor costs, which can no longer meet the development trend of modern industrial processes. Therefore, there is an urgent need to design a multi-functional roll-on transfer vehicle for tire manufacturing to help production workers complete the transfer of tire rubber sheets. Summary of the Invention

[0003] In response to the above situation, this utility model provides a multi-functional I-beam wheel transfer vehicle for tire manufacturing, which can greatly assist manual labor in completing the transfer of tire rubber sheets more easily and efficiently.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multifunctional tire rolling trolley for tire manufacturing includes a tire, a film wound on the tire, and an insulating strip placed between the film, as well as a rolling trolley for rolling the tire. The rolling trolley includes a frame assembly and a wheel assembly. The frame assembly includes a U-shaped support frame. A left stretcher and a right stretcher are provided on the left and right sides of the bottom center of the support frame to assist in lifting the tire. The tire is placed horizontally between the two stretchers in the front-to-back direction. A front support plate and a rear support plate are fixed to the top of the front and rear sides of the support frame for placing the insulating strip rolled up after the film is removed. Several pairs of positioning wedges are provided on the front and rear sides of the upper surface of the front and rear support plates to prevent the insulating strip from rolling off.
