Description

Technical Field

[0001] The utility model relates to the technical field of water bath forming tanks for polymer materials, and particularly relates to a water bath forming tank for polymer material cushions. Background Art

[0002] At present, polymer material cushions such as seat cushions, mattress pads, and backrest pads are widely made of polyolefin elastomer (POE) materials. Since polyolefin elastomer (POE) is a thermoplastic elastomer with a melting point of only 50°C - 70°C, which is lower than the boiling point of water under atmospheric pressure, a double-sided flat panel made of polyolefin elastomer (POE) can be first placed in a mold, and then immersed together in hot water in a hot water tank that is higher than its melting point for water bath heating and forming, and then immersed together in cold water in a cold water tank that is lower than its melting point for water bath cooling and shaping, and then the mold is opened to obtain cushions such as seat cushions and mattress pads made of polyolefin elastomer (POE) with the target shape. Content of the Utility Model

[0003] The purpose of the utility model is to provide a water bath forming tank for polymer material cushions of polyolefin elastomer (POE).

[0004] To solve the above technical problems, the technical solution provided by the utility model is as follows:

[0005] A water bath forming tank for polymer material cushions includes a hot water tank and a cold water tank;

[0006] Both the hot water tank and the cold water tank include a water bath tank, a lifting frame, an electric telescopic rod, a rope, a fixed pulley, and a hanging cage;

[0007] The water bath tank is placed at the inner bottom of the lifting frame. The water bath tank in the hot water tank is used to hold hot water, and the water bath tank in the cold water tank is used to hold cold water;

[0008] The electric telescopic rod is fixedly arranged on the outer wall of the rear side wall of the water bath tank. The telescopic rod in the electric telescopic rod is arranged vertically, and the top end of the telescopic rod is connected to one end of the rope;

[0009] The fixed pulley is arranged at the inner top of the lifting frame. The rope passes through the fixed pulley to form a pulley hoisting structure, and the other end of the rope is connected to the top of the hanging cage;

[0010] The hanging cage is located inside the lifting frame, and is used for the extension of the electric telescopic rod to drive the hanging cage to descend and immerse in the water bath tank, and the retraction of the electric telescopic rod to drive the hanging cage to rise and leave the water bath tank;

[0011] The cage is a double-layer rectangular frame structure welded by horizontal transverse tubes, horizontal longitudinal tubes and vertical tubes. The lower layer of the cage is used to place the molds for water bath.

[0012] When the cage is at the lower limit position and in the water bath tank, the upper surface of the upper layer of the cage, the top grooves of the two water bath tanks are all horizontally flush, so as to form a platform for the horizontal movement of the molds.

[0013] When the cage is at the upper limit position and above the water bath tank, the upper surface of the lower layer of the cage, the top grooves of the two water bath tanks are all horizontally flush, so as to form a platform for the horizontal movement of the molds.

[0014] The cage is provided with a lower limit protruding tube, which is used to make the cage reach the lower limit when the lower limit protruding tube descends and lands on the top groove edge of the water bath tank.

[0015] Preferably, the lifting frame is a vertical rectangular frame structure assembled by horizontal transverse aluminum alloy profiles, horizontal longitudinal aluminum alloy profiles and vertical aluminum alloy profiles.

[0016] Preferably, the lower layer of the cage is provided with a lower front guard plate and a lower rear guard plate for guiding and limiting the horizontal movement of the molds.

[0017] The upper layer of the cage is provided with an upper front guard plate and an upper rear guard plate for guiding and limiting the horizontal movement of the molds.

[0018] When one cage is at the lower limit position and the other cage is at the upper limit position, the upper front guard plate of the cage at the lower limit position is aligned and in contact with the lower front guard plate of the cage at the upper limit position, and the upper rear guard plate of the cage at the lower limit position is aligned and in contact with the lower rear guard plate of the cage at the upper limit position.

[0019] The present application has achieved the following beneficial technical effects:

[0020] In the present application, the cage of the hot water tank is at the upper limit position. Then, the molds are placed on the lower layer of the cage of the hot water tank. Then, the extension of the electric telescopic rod of the hot water tank drives the cage of the hot water tank to descend until the lower limit position, and immerses it in the hot water in the water bath tank of the hot water tank for plastic shaping. After a certain time of hot water bath, the retraction of the electric telescopic rod of the hot water tank drives the cage of the hot water tank to rise and leave the water bath tank of the hot water tank until the upper limit position. Thus, the hot water bath plastic shaping is completed.

[0021] The hanging cage of the cold water tank is at the upper limit position. Then, place the mold on the lower layer of the hanging cage of the cold water tank. Then, the extension of the electric telescopic rod of the cold water tank drives the hanging cage of the cold water tank to descend until the lower limit position, and it is immersed in the cold water of the water bath tank of the cold water tank for shaping. After a certain period of cold water bath, the retraction of the electric telescopic rod of the cold water tank drives the hanging cage of the cold water tank to rise and leave the water bath tank of the cold water tank until the upper limit position. Thus, the cold water bath shaping is completed;

[0022] The water bath forming tank is located in the middle of the production line. An inlet conveyor platform for conveying the mold is arranged upstream, and an outlet conveyor platform for conveying the mold is arranged downstream. Therefore, in order to enable the mold to pass through the water bath forming tank from the inlet conveyor platform and then reach the outlet conveyor platform, on the basis of the two functions of hot water bath shaping and cold water bath shaping, the water bath forming tank is also provided with a platform for the mold to move smoothly from left to right horizontally through the water bath forming tank: when the hanging cage is at the lower limit position and in the water bath tank, the upper surface of the upper layer of the hanging cage, the top grooves of the two water bath tanks are all horizontally flush, so as to form a platform for the horizontal movement of the mold; when the hanging cage is at the upper limit position and above the water bath tank, the upper surface of the lower layer of the hanging cage, the top grooves of the two water bath tanks are all horizontally flush, so as to form a platform for the horizontal movement of the mold; when the two hanging cages are both at the lower limit position, when the two hanging cages are both at the upper limit position, when one hanging cage is at the upper limit position and the other hanging cage is at the lower limit position, the combination of the upper surfaces of the upper and lower layers of the hanging cage can all enable the mold to successfully move horizontally through the water bath forming tank, just like building a bridge platform, and the mold successfully passes through the bridge platform and moves horizontally back and forth;

[0023] In summary, the water bath forming tank provided by this application has the advantages of simpler structure, higher efficiency, and more reasonable design. Description of the Drawings
