Description

Technical Field

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

[0002] Condom production is an assembly line production, with batches of condom molds connected to a circular transmission chain. Under the transmission of the transmission chain, the condom molds arranged in order on the transmission chain pass through the condom mold cleaning equipment, liquid rubber pool, condom flanging equipment, and condom demoulding equipment. Among them, at the liquid rubber pool, the condom mold has a running track of descending and then ascending. In this running track, the condom mold descends and immerses in the liquid rubber pool, and the liquid rubber adheres to the condom mold to initially form the condom.

[0003] In actual production, when a batch of condoms is completed, after the last number of condoms are initially formed in the liquid rubber pool, the subsequent condom molds do not need to be immersed in the liquid rubber pool again. Or, the production line is shut down and the condom molds need to be separated from the liquid rubber pool. In the above cases, the liquid rubber pool and the condom molds are required to be separated. Utility Model Content

[0004] The technical problem solved by the utility model is how to separate the liquid rubber pool from the condom mold.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a lifting type raw material supply equipment, including a rubber pool, a heating device arranged at the bottom of the rubber pool, a left cavity is arranged on the left side of the rubber pool, and a right cavity is arranged on the right side of the rubber pool. The left cavity, the right cavity and the middle part between the left and right cavities can circulate liquid rubber, and a stirring blade is arranged in the right cavity. Two pairs of lifting devices are arranged at the bottom of the rubber pool, and the two pairs of lifting devices are distributed at the four corners of the bottom of the rubber pool. The two lifting devices of each pair of lifting devices are linked.

[0006] According to the above technical solution, the rubber pool can be raised and lowered under the drive of two pairs of lifting devices. When the rubber pool rises, the condom mold on the transmission chain can be immersed in the rubber pool. When the rubber pool descends, the lowest point of the condom mold passing through the rubber pool is higher than the top surface of the rubber pool, and the condom mold on the transmission chain will not be immersed in the rubber pool. The utility model can separate the liquid rubber pool from the condom mold.

[0007] Any lifting device includes a screw rod and a transmission device matched with the screw rod. The two transmission devices of any pair of lifting devices are connected by a transmission shaft, and the transmission shaft is connected to the motor through a transmission chain. Driven by the motor, the two transmission devices of a pair of lifting devices operate synchronously. The two motors act synchronously to drive the two pairs of lifting devices to operate synchronously. The two pairs of lifting devices smoothly lift or lower the rubber pool.

[0008] The heating device is located between the left cavity and the right cavity. The left cavity is provided with a left top outlet and a left bottom inlet on the side facing the right cavity, and the right cavity is provided with a right top inlet and a right bottom outlet on the side facing the left cavity.

[0009] The worker adds liquid rubber to the right chamber, and the stirring blade drives the liquid rubber to flow out of the right chamber from the right bottom outlet and into the middle space of the rubber pool. In the middle space of the rubber pool, the heating device heats the liquid rubber, and driven by the stirring blade, the liquid flow pushes the liquid rubber at the bottom of the middle space of the rubber pool to the left bottom inlet, and the liquid rubber enters the left chamber. The liquid rubber in the left chamber accumulates, flows out through the left top outlet, and enters the middle space of the rubber pool. While the stirring blade drives the liquid rubber downward to flow to the left, a low-pressure area is formed on its top, and the liquid rubber in the upper part of the middle space of the rubber pool enters the low-pressure area, that is, the liquid rubber enters the right chamber through the right top inlet. Afterwards, driven by the stirring blade, the liquid rubber in the right chamber flows out of the right bottom outlet and enters the middle space of the rubber pool. In this way, driven by the stirring blades, the liquid rubber circulates in the order of right chamber, right bottom outlet, middle space of the rubber pool, left bottom inlet, left chamber, left top outlet, middle space of the rubber pool, and right chamber.

[0010] During the circulation of the liquid rubber, the heat of the heating device is evenly diffused throughout the liquid rubber, so that all rubber in the liquid rubber pool can maintain a uniform temperature, which not only prevents the liquid rubber from solidifying, but also helps improve the quality of the product.

[0011] A stirring blade support is provided at the bottom of the right chamber, a stirring blade bracket is provided at the top of the right chamber, the bottom of the stirring blade shaft is mounted on the stirring blade support, the top of the stirring blade shaft is mounted on the stirring blade bracket, and the top of the stirring blade shaft is connected to the motor through a transmission mechanism. The stirring blade shaft is pivotally connected to the stirring blade support, the stirring blade shaft is pivotally connected to the stirring blade bracket, and both ends of the stirring blade bracket are mounted on the top of the rubber pool. Driven by the motor, the stirring blade shaft and the stirring blade rotate.

[0012] As an option, the stirring blade shaft is connected to the motor through a transmission chain, and the motor is installed on the outer side wall of the rubber pool.

[0013] A disc-shaped baffle is provided on the stirring blade shaft, and the disc-shaped baffle is located above the stirring blade. The disc-shaped baffle is located in the right cavity, and there is a gap between the disc-shaped baffle and the inner wall of the right cavity. Liquid rubber is poured into the right cavity and falls on the disc-shaped baffle. The disc-shaped baffle rotates with the stirring blade shaft to disperse the liquid rubber on it. The liquid rubber flows into the space where the stirring blade of the right cavity is located through the gap between the disc-shaped baffle and the inner wall of the right cavity. Therefore, the disc-shaped baffle has the function of dispersing the hydraulic rubber. The stirring blade drives the liquid rubber to flow downward in the right cavity, and the disc-shaped baffle has the function of pressing down the liquid rubber, so that the liquid rubber can flow in one direction under high pressure.

[0014] The top side wall of the right cavity is provided with a transverse extension portion pointing to the left cavity, and the tail end of the transverse extension portion is bent upward to be in an upright shape. The tail end of the upwardly bent transverse extension portion is lower than the height of the rubber pool, so the space between the tail end of the upwardly bent transverse extension portion and the top surface of the rubber pool constitutes the right top inlet. The liquid rubber in the middle space of the rubber pool enters the transverse extension portion through the right top inlet and then enters the right cavity. Since the transverse extension portion has a large area, the liquid rubber can be effectively dispersed after passing through the transverse extension portion and then flows into the right cavity, which is conducive to uniform texture and temperature of the liquid rubber.

[0015] The left chamber is composed of the side wall of the rubber pool, the bottom of the rubber pool and a vertical baffle. The top of the vertical baffle is lower than the top of the rubber pool, forming the left top outlet; the bottom of the vertical baffle is higher than the bottom of the rubber pool, forming the left bottom inlet.

[0016] A slot structure is provided on the side wall of the rubber pool, and the vertical baffle is fitted in the slot structure and fixed with threaded fasteners. By loosening the threaded fasteners, the vertical baffle can be raised and lowered along the slot structure. After reaching a suitable height, the threaded fasteners are tightened to fix the position of the vertical baffle. The height adjustment of the vertical baffle can adjust the size of the left top outlet and the left bottom inlet, thereby adjusting the flow rate of the liquid rubber in the rubber pool. The appropriate flow rate can keep the liquid rubber flowing while efficiently adhering to the condom mold.

[0017] The side wall of the rubber pool adopts a double-layer structure, which has a heat-insulating effect, helping the liquid rubber to remain in liquid form and avoid solidification.

[0018] The rubber pool is a double-cavity structure arranged in parallel front and back. The double cavities are respectively a front cavity and a rear cavity. The front cavity and the rear cavity are connected at the bottom. The front cavity and the rear cavity are provided with a separate left cavity, and the front cavity and the rear cavity share a right cavity. The condom molds on the transmission chain are distributed on the front and rear sides of the transmission chain. Under the drive of the same transmission chain, the condom molds on both sides can be simultaneously immersed in the front cavity and the rear cavity of the rubber pool, so that the production efficiency of condoms can be improved.
