Description

Technical Field

[0001] The utility model relates to an automatic ball head patch cutting device, belonging to the technical field of ball bladder processing. Background Art

[0002] There are various kinds of balls on the market, such as leather balls used in sports, including basketballs, volleyballs, footballs, etc., as well as small inflatable balls for children to play with. In the process of making the inner bladder of the inflatable ball, natural rubber is folded, and then the bladder is cut out by a press. After inflation, it passes through a curing machine and is heated and cured to form a rubber bladder.

[0003] In the existing ball bladder processing process, the rubber made of natural rubber needs to be cut into individual films, and holes need to be punched on the films, and the ball heads need to be glued for the subsequent installation of the air valve. This production process is also called ball head patching. Existing ball production companies mostly use manual operation to perform ball head patching operations. Due to manual operation, there are several problems: (1) Manual operation causes a large workload and low production efficiency during mass production. (2) Manual operation makes it difficult to control the length of a single rubber sheet, which can easily cause the length to be too large, resulting in film waste, while if the length is too small, the subsequent press will not be able to cut out the completed ball bladder. (3) Manual operation makes it impossible for the inflation hole of the ball head to be concentrically aligned with the punched hole of the film, resulting in the inflation hole of the ball head being partially covered by the film and unable to be subsequently inflated, resulting in waste. Therefore, there is an urgent need for an automatic ball head patching device to solve the problems of manual ball head patching in the existing technology, which causes a large workload, low production efficiency and poor ball bladder production quality.

[0031] Working principle: Before using the automatic cutting ball head patch equipment of this embodiment, the operator first inputs parameters in the human-machine interface according to the length size and punching position size of the cut single film to control the punching time of the punching component, the pressing time of the ball head pressing component and the cutting time of the cutting component. This ensures the punching position of a single film, the ball head feeding position and the film feeding length after the ball head presses the patch. Then the operator installs the ball head material tray loaded with the ball head to the ball head loading unit, and finally puts the rubber head of the rubber loading component into the first transport line to complete the rubber loading preparation and the equipment debugging.

[0032] When the automatic cutting ball head patch equipment is working, the rubber is first driven by the driving belt of the first conveyor line and fed along the first conveyor line. When the rubber is transferred to the punching station, the punching cylinder is started to drive the upper punching head to punch the rubber in the direction of the lower punching head. After the rubber is punched, it is transferred to the ball head pressing station. At the same time, at the ball head pressing assembly, the operator manually takes the ball head on the ball head material tray or uses the material taking device to place it on the lower pressing head for loading. Then the first drive motor drives the lower pressing head mounting plate, that is, drives the lower pressing head to move to the ball head pressing station.

[0033] After the punched rubber and ball head are transferred to the ball head pressing station, the upper and lower pressure head cylinders are started, driving the upper and lower pressure heads to press the rubber and ball head to the patch. After completion, the components are reset, and the rubber continues to be fed to the cutting station. When the rotary encoder detects that the feeding length of the rubber reaches the cutting size, the rubber stops feeding, the cutting cylinder is started, and the upper cutting knife is driven to cut the rubber to form a finished ball head patch, completing a ball head patch work. Finally, the finished ball head patch is transferred to the subsequent station or collected as a finished product via the second transport line. In this way, the ball head patch is automatically produced.
