Description

Technical Field

[0001] The present invention relates to the technical field of latex pillow preparation, and specifically to a foaming machine for mixing and preparing latex products and a preparation method thereof. Background Technique

[0002] A foaming machine for mixing and preparing latex products is a device specifically used for producing latex foam materials. When preparing a latex pillow, it is necessary to mix and foam the existing latex materials, and only then can the materials at the foaming port be used to prepare the latex pillow.

[0003] In the prior art, when mixing and foaming latex products, when the latex material is foamed, air is pumped into the latex product for internal mixing through a blower. If there are impurities in the pumped air, it is likely to affect the mixing quality of the latex product.

[0004] To overcome the above deficiencies, a Chinese patent of the prior art (publication number CN218928413U) discloses a latex foaming machine for producing a latex pillow with uniform mixing. It includes a foaming machine box body and a connecting plate. The outer wall of the foaming machine box body is fixedly connected with the connecting plate, and a wind box is fixedly connected to the surface of the connecting plate. A lifting mechanism is provided at the top of the foaming machine box body. The first motor in the lifting mechanism drives the first bevel gear set to rotate, thereby driving the right-end pin shaft to rotate. The right-end pin shaft drives the first gear to rotate, thereby driving the second gear to rotate. The second gear drives the rack to slide in the sleeve, and the rack drives the connecting block to move, thereby driving the air pipe to move. When the nozzle at the bottom of the air pipe moves to the bottom of the foaming machine box body, the rack drives the air pipe to move up and down. When uniform foaming is required, the air pipe descends. After the uniform foaming is completed, the air pipe rises. The uniformly foamed latex will not block the air pipe, and there is no need for regular maintenance, reducing the cost of the foaming machine.

[0005] To overcome the above deficiencies, a Chinese patent of the prior art (publication number CN214353736U) discloses a latex foaming machine for producing a latex pillow with uniform mixing. This latex foaming machine for producing a latex pillow with uniform mixing includes a material extraction box. A material taking box is fixedly installed at the bottom of the material extraction box, a stirring box is fixedly installed at the top of the material extraction box, a first feeding tank and a second feeding tank are fixedly installed at the top of the stirring box. The bottoms of the first feeding tank and the second feeding tank are both fixedly installed with feeding pipes and are communicated with their interiors. The feeding pipes extend into the interior of the stirring box. Feeding pipes are fixedly installed at the tops of the first feeding tank and the second feeding tank. A stirring rod is rotatably installed on one inner wall of the stirring box. Through the combined use of a motor, the stirring rod and the auxiliary stirring rods, the latex fusion agent in the stirring box is fully stirred to combine with air, greatly improving the quality of the latex pillow, which is very economical and easy to use.

[0006] Although the prior art can overcome the above-mentioned deficiencies, there are still other problems in its operation. For example, when mixing latex products, the stirring rods for mixing and stirring foam in the same direction, resulting in relatively low mixing and stirring effects, long time consumed for stirring and mixing, and affecting the foaming efficiency.

[0013] Further, a groove push rod is penetrated and installed on the right side of the transfer bin. The groove push rod is in a "T" shape. A positioning column is arranged inside the right groove of the groove push rod. The lower end of the positioning column is fixedly installed with a disc.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When in use, latex product materials are added through the feed port. After the materials fall into the interior of the casing, by starting the drive motor, the start of the drive motor can drive the movable sleeve rod to rotate. When the movable sleeve rod rotates, through the special shape at the bottom, it can drive the stirring sleeve to rotate, achieving a stable stirring effect; Furthermore, when the exhaust fan is started, when the exhaust fan extracts air, the gas is conveyed to the transfer bin through the connecting pipe. After the gas is filtered by the filter screen plate inside the transfer bin, under the action of the air injection pipe, it is conveyed into the materials inside the casing. Through the bearing, the stirring sleeve can be driven to adjust the reciprocating height along the movable sleeve rod, thereby achieving the effect of efficient mixing and stirring, further improving the stirring and foaming effect. With the setting of the observation window on the surface of the casing, it is convenient to observe the mixing and foaming degree of the latex products inside the casing. After the latex products are foamed, they are discharged by starting the discharge valve.

[0019] 2. When the threaded rod rotates, it can drive the upper disk to rotate synchronously. When the disk rotates, it can drive the positioning column on its surface. The movement of the positioning column drives the groove push rod sleeved on its surface. Under the limit of the left transfer bin, the groove push rod can move reciprocally. With the setting of the damper, it can stably press the cleaning brush, making the cleaning brush closely fit the filter screen plate. As the movable plate reciprocates, it can clean the filter screen plate cyclically, achieving the effect of auxiliary cleaning, avoiding the blockage of the filter screen plate, ensuring the gas transmission efficiency, and further improving the foaming efficiency.

[0020] 3. When discharging, as the groove push rod reciprocates, the movable plate on the surface of the groove push rod reciprocates to squeeze the inclined part at the upper end of the movable bin. The movable bin is squeezed to stretch the pressure spring along the upper end of the casing. At this time, as the movable bin presses down the rotating knocking plate, the rotating knocking plate rotates along the inside of the positioning block. When the rotating knocking plate rotates and is squeezed by the movable bin under its own "L" shape setting, while stretching the torsion spring, it knocks the air injection pipe through the convex block, so that the remaining impurities inside the air injection pipe can be evenly discharged, avoiding the remaining of the foamed materials inside the air injection pipe and blocking, and avoiding the waste of materials.

A filter screen plate 22 is fixedly installed inside the transfer bin 10. A groove push rod 20 is installed through the right side of the transfer bin 10, and the shape of the groove push rod 20 is "T" shaped. A positioning post 19 is arranged inside the right-side groove of the groove push rod 20. The lower end of the positioning post 19 is fixedly installed on the upper end of a threaded rod 14. A movable plate 21 is fixedly installed on the left side of the groove push rod 20. A cleaning brush 24 is arranged inside the movable plate 21. A return spring 23 is arranged between the cleaning brush 24 and the movable plate 21. The lower end of the cleaning brush 24 is in contact with the surface of the filter screen plate 22. A damper 25 is installed through the middle of the movable plate 21, and the lower end of the damper 25 is fixedly installed on the upper end of the cleaning brush 24.

[0036] When the threaded rod 14 rotates, it can drive the upper disk 18 to rotate synchronously. When the disk 18 rotates, it can drive the positioning post 19 on its surface. The movement of the positioning post 19 drives the groove push rod 20 sleeved on its surface. Under the limitation of the left-side transfer bin 10, the groove push rod 20 can reciprocate. The reciprocating groove push rod 20 can drive the movable plate 21 to move. With the arrangement of the internal cleaning brush 24, the reciprocating movable plate 21 can clean the surface of the filter screen plate 22.

[0038] When discharging materials, with the reciprocating movement of the groove push rod 20, the moving plate 26 on the surface of the groove push rod 20 reciprocates to squeeze the inclined part at the upper end of the movable bin 27. The movable bin 27 is squeezed to stretch the pressure spring 28 along the upper end of the casing. At this time, as the movable bin 27 presses down the rotating knocking plate 30, the rotating knocking plate 30 rotates along the inside of the positioning block 29.
