Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tire production equipment, specifically to a tire forming machine rubber sheet support device. Background Technology
[0002] The sidewall is a crucial component of a tire. Its primary functions are to protect the tire carcass from damage, withstand flexural deformation, distribute tire weight, and provide additional durability and strength, thus requiring sufficient strength. To improve sidewall strength, a reinforcing rubber sheet is added during tire forming. In traditional tire forming machines, the rubber sheet is fed out and wound around the bonding drum, wrapping around the tire sidewall. Since the rubber sheet is a stretchable material, the lack of support underneath after feeding can cause it to pull down. During the feeding and transport process, the rubber sheet becomes thinner and narrower due to stretching, resulting in a longer cut length than required. This leads to thinner tread areas, causing visible lines on the shoulder or crown of the vulcanized tire, affecting tire quality. Utility Model Content
[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background art and to provide a tire forming machine film support device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A tire forming machine film support device includes an extension mold frame, a film support plate, a belt, and several rollers. The extension mold frame is slidably mounted on the machine frame, and a working surface is provided on the top of the extension mold frame. The rear end of the belt is fixed to the machine frame. After the belt passes through several rollers in sequence, the front end of the belt is fixed to the film support plate. Any roller is located between the extension mold frame and the film support plate. The belt between the roller and the film support plate is configured as a belt support section, which is used to provide support for the film. The film reaches the extension mold frame after passing from the film support plate through the belt support section.
[0006] In some embodiments of this utility model, the film support plate is arranged behind the protruding mold frame, and the working surface is arranged on the side close to the film support plate.
[0007] In some embodiments of this utility model, the support wheel rotatably mounted at the front end of the extending mold frame is located below the fitting drum when the extending mold frame slides out.
[0008] In some embodiments of this utility model, a tensioning device is installed on the inner side of the belt.
[0009] In some embodiments of this utility model, the roller includes a first roller, a second roller, and a third roller located between the protruding mold frame and the film support plate, and the belt passes around the first roller, the second roller, and the third roller in sequence.
[0010] In some embodiments of this utility model, the belt turns upward after passing over the first roller, the second roller is located between the horizontal plane where the first roller is located and the horizontal plane where the third roller is located, and the belt turns towards the film support plate after passing over the third roller.
[0011] In some embodiments of this utility model, the third roller is configured as a tension roller, which is connected to the rear end of the protruding mold frame via a guide block.
[0012] In some embodiments of this utility model, one end of the belt is mounted on the frame via a tail fixing block, and the extended mold frame is provided with a placement space to accommodate the belt and the tail fixing block, while the other end of the belt is mounted on the film support plate via a front fixing block.
