Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sponge production, in particular to a horizontal foaming machine for sponge production. Background Art
[0002] There are three main foaming methods for sponge production: physical foaming, chemical foaming, and a combination of physical and chemical foaming. At present, the production process of PVA sponge absorbent materials in China mostly adopts the backward starch filling foaming method, that is, filling starch into the PVA solution at an appropriate temperature, cross-linking and curing the PVA at a certain temperature, and then washing away the starch. This method causes serious environmental pollution during production, and the subsequent processing steps are long. The starch cannot be completely washed, and the starch and acid catalyst cannot be completely recycled, which is not conducive to saving resources and reducing costs.
[0003] When foaming the PVA solution, it is necessary to add a sufficient amount of air to the solution. The existing foaming device cannot fully add air to the solution, which will result in poor foaming effect and is not conducive to the production of sponges. Secondly, the stirring device only stirs the solution at the bottom of the stirring box, and the number of stirring devices is small, which has a poor stirring effect on the solution. Finally, when the solution is poured out of the stirring box after stirring, the pouring speed cannot be controlled. The hydraulically controlled hydraulic cylinder will directly flip the stirring box, and the solution will be completely poured out of the stirring box in a very short time. Therefore, in view of the above problems, a horizontal foaming machine for sponge production is proposed. Utility Model Content

[0023] See also Figure 1-4 , the utility model provides a technical solution:
[0024] A horizontal foaming machine for sponge production comprises a support leg 1, a cross bar 2 is rotatably connected to the outer side of the support leg 1, a mixing box 3 is fixedly connected to one end of the cross bar 2, a motor 4 is fixedly connected to the bottom end of the mixing box 3, a rotating shaft 5 is fixedly connected to one end of the motor 4, a stirring rod 6 is fixedly connected to the outer side of the rotating shaft 5, annular grooves 7 are provided at both ends of the stirring rod 6, a vertical rod 8 is rotatably connected to the outer side of the annular groove 7, straight rods 9 are rotatably connected to the two ends of the vertical rod 8, a worm gear 10 is fixedly connected to one end of another cross bar 2, a fixing frame 11 is fixedly connected to the outer side of the support leg 1, a rotating shaft 12 is rotatably connected to the inside of the fixing frame 11, a handle 13 is fixedly connected to one end of the rotating shaft 12, and a worm 14 is fixedly connected to the outer side of the rotating shaft 12.
[0025] A fixing plate 15 is fixedly connected to one side of the leg 1 close to the mixing box 3, an air pump 16 is fixedly connected to the top of the fixing plate 15, a circular air stone 17 is fixedly connected to the bottom end of the inside of the mixing box 3, a connecting pipe 18 is fixedly connected to the outer side of the top of the air stone 17, and an air pipe 19 is fixedly connected to one end of the connecting pipe 18; there are two legs 1, which are symmetrically arranged on the outside of the mixing box 3; there are three stirring rods 6, and the upper and lower adjacent stirring rods 6 are in a perpendicular relationship to each other in the horizontal plane; one end of the air pipe 19 away from the connecting pipe 18 is fixedly connected to the air pump 16.
[0026] Working process: When the device is used, the device is first placed in a suitable position, and an external power supply is used to power the motor 4 and the air pump 16 of the device. Before stirring the solution, the stirring box 3 is first placed in a horizontal position by turning the handle 13, and then the solution to be stirred is added into the stirring box 3, and then the air pump 16 at the top of the fixed plate 15 is started. The compressed air generated by the air pump 16 reaches the bubble stone 17 through the air pipe 19 and the connecting pipe 18, and then small bubbles are formed from the surface of the bubble stone 17 and reach the solution. The motor 4 drives the rotating shaft 5 to rotate, and the stirring rod 6 rotates horizontally driven by the rotating shaft 5. The vertical rod 8 rotates on the outside of the annular groove 7 by itself. The straight rod 9 and the vertical rod 8 are rotatably connected, so when the rotating shaft 5 drives the stirring rod 6 to rotate, affected by the solution, a certain rotation will also occur between the straight rod 9 and the vertical rod 8, so that the solution can be stirred better, and The stirring rods 6 are provided with three groups, which can fully stir solutions at different heights, reduce the stirring time, and increase the stirring rate. When the solution is stirred, the air pump 16 is stopped, and air is no longer provided to the solution. The motor 4 is stopped and stirring is stopped. Then the handle 13 is turned, and the handle 13 drives the rotating shaft 12 to rotate on the fixed frame 11. The worm 14 meshing with the worm gear 10 on the outside of the rotating shaft 12 rotates, and the worm 14 drives the worm gear 10 to rotate. The worm gear 10 drives the cross bar 2 to rotate, and the stirring box 3 can be turned over by driving the cross bar 2 to rotate, and the solution in the stirring box 3 can be poured out. Since the worm wheel 10 and the worm 14 can form a self-locking, after the stirring box 3 is turned over a certain angle, when the staff does not turn the handle 13, the stirring box 3 will not automatically rotate around the cross bar 2 under the influence of factors such as gravity, and the pouring speed of the solution in the stirring box 3 can be controlled by the worm wheel 10 and the worm 14.
