Description

Technical Field

[0001] The utility model relates to sanitary products, in particular to production equipment for condoms. Background Art

[0002] Condoms are rubber products. During the production process, the condom mold is dipped in a pool of liquid rubber, and the liquid rubber adheres to the condom mold. The condom mold exits the liquid rubber pool, and after cooling, the rubber on it forms a condom prototype. After that, the condom prototype needs to be flanging. After that, the condom is separated from the mold through the demoulding process. The production of condoms is an assembly line operation, which requires a conveying structure to drive the condom mold through the liquid rubber pool, the flanging device, and the demoulding mechanism.

[0003] The transmission structure includes a transmission chain and a mold base connected to the transmission chain. The mold base is connected to the transmission chain through a transmission connecting rod. The mold base includes a tail kit hinged to the transmission connecting rod and a mold base body pivotally connected to the tail kit. The mold base body is provided with a positioning groove, and the condom mold is inserted in the positioning groove. A mold base guide and limit structure is provided on the side of the transmission chain. The mold base guide and limit structure limits and guides the running trajectory of the mold base and the condom mold thereon.

[0004] The transmission chain drives the mold seat through the transmission connecting rod, and the mold seat drives the condom mold installed thereon. Since the mold seat is hinged to the transmission connecting rod, the mold seat and the condom mold thereon can swing up and down relative to the transmission connecting rod. Under the restriction and guidance of the mold seat guide limit structure, with the transmission of the transmission chain, the mold seat and the condom mold thereon can be in a lying state, an upright state, or an inclined state. When in the upright state, the condom mold can be immersed in the liquid rubber pool. When in the lying state, the flanging device located beside the transmission structure can flanging the condom prototype on the mold. When in the inclined state, the demoulding mechanism located beside the transmission structure can peel the condom formed on the condom mold from the mold.

[0005] The transmission chain forms a closed loop, driving the mold base and the condom mold to circulate. At the sprocket, the transmission track of the transmission chain is a semicircle, and the mold base and the condom mold on the transmission chain flip accordingly. Utility Model Content

[0008] When the transmission chain passes through the sprocket, the transmission track of the transmission chain is semicircular, and the mold seat on the transmission chain enters the bottom entrance formed by the inner arc guide strip and the outer arc guide strip, enters the arc guide groove formed by the inner arc guide strip and the outer arc guide strip, and then leaves the arc guide groove through the top exit formed by the inner arc guide strip and the outer arc guide strip. Due to the guidance of the arc guide groove, the mold seat and the condom mold on it can be turned over at the sprocket with the transmission chain, providing hardware conditions for the production of condom assembly lines.

[0009] The outer supporting frame fixes the outer arc-shaped guide strip, the bottom of the outer supporting frame is connected to the bottom bracket, and the top of the outer supporting frame is connected to the ceiling to prevent the outer supporting frame from interfering with the operation of the mold seat and the condom mold.

[0010] The inner support frame fixes the inner arc-shaped guide strip, and the inner support frame is arranged transversely and passes through the transmission chain, and the two ends of the inner support frame are located outside the condom mold on the transmission structure. In this way, the inner support frame will not interfere with the condom mold.

[0011] The bottom bracket comprises a column, a horizontal longitudinal beam and a horizontal cross beam arranged on the column, the bottom of the outer supporting frame is arranged on the horizontal cross beam, and the two ends of the inner supporting frame are arranged on the horizontal longitudinal beam.

[0012] The central axis of the sprocket is installed on the horizontal longitudinal beam through a bearing seat.

[0014] The inner diameter of the outer arc guide strip is larger than the outer diameter of the sprocket, and the outer diameter of the inner arc guide strip is smaller than the outer diameter of the sprocket. In this way, when the mold seat and the condom mold thereon pass through the arc guide groove formed by the outer arc guide strip and the inner arc guide strip, the condom mold is perpendicular to the sprocket, which is conducive to the stable flipping of the condom mold and passing through the sprocket.

[0015] An auxiliary support structure is provided in the inner circle of the inner arc-shaped guide strip, and the auxiliary support structure props up the inner arc-shaped guide strip to form an arc shape. The auxiliary support structure is located in the inner arc-shaped guide strip, and the inner arc-shaped guide strip surrounds the auxiliary support structure, and the auxiliary support structure is welded to the inner arc-shaped guide strip. The two ends of the inner arc-shaped guide strip are closed and welded to the inner support frame. BRIEF DESCRIPTION OF THE DRAWINGS
