Description

Technical Field

[0001] This utility model belongs to the field of sponge production, specifically a foaming device for sponge production. Background Technology

[0002] A sponge is a porous material with excellent water absorption, used for cleaning. Commonly used sponges are made from wood cellulose fibers or foamed plastic polymers. There are also natural sponges made from sponge animals, most of which are used for body cleaning or painting. Additionally, there are three other types of synthetic sponges made from materials such as low-density polyether, polyvinyl alcohol, and polyester. Regardless of the material, all sponge production requires a foaming process.

[0003] Most existing technologies use a nozzle to spray foam into a molding box. However, the nozzle position is not easy to adjust, and the sprayed foam can only accumulate upwards in the molding box, causing the molded sponge to bulge. Moreover, after the foam is sprayed, a large number of sharp corners will gather on its surface. After foaming, these sharp corners will form protrusions, affecting the appearance of the molded sponge. At the same time, the nozzle will also spray dead corners. The amount of foam sprayed in the dead corners is less, which will cause the molded sponge to be sunken.

[0004] Therefore, this utility model provides a foaming device for sponge production. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, which mostly involve spraying foam into a molding box using a nozzle, the nozzle position is not easily adjustable. The sprayed foam can only accumulate upwards inside the molding box, causing the molded sponge to bulge. Furthermore, after the foam is sprayed, a large number of sharp corners will gather on its surface, forming protrusions after foaming, affecting the appearance of the molded sponge. At the same time, the nozzle will also spray dead corners, where less foam is sprayed, leading to the problem of the molded sponge being sunken. This utility model proposes a foaming device for sponge production.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 7 As shown, this utility model provides a technical solution: a foaming device for sponge production, including a base 1. Two sets of supports 2 are symmetrically fixedly connected to the top of the base 1. A material cylinder 3 is fixedly connected between the two sets of supports 2. A feed inlet 4 is opened at the top of the material cylinder 3. A fixed frame 5 is fixedly connected to the bottom of the material cylinder 3. A first motor 6 is fixedly connected to one side of the fixed frame 5. The output end of the first motor 6 extends into the interior of the fixed frame 5 and is fixedly connected to a lead screw 7. The lead screw 7 is rotatably connected to the fixed frame 5. A slider 8 is connected to the outer wall of the lead screw 7 through a lead screw nut pair. The slider 8 is slidably connected to the fixed frame 5. A nozzle 9 is fixedly connected to the bottom of the slider 8. A slurry pump 10 is fixedly connected to the bottom of the material cylinder 3. A connecting pipe 11 is fixedly connected to the output end of the slurry pump 10. One end of the connecting pipe 11 extends into the interior of the material cylinder 3, and the other end of the connecting pipe 11 is connected to the nozzle 9. A molding box 24 is provided at the top of the base 1 and below the nozzle 9.

[0027] Through the above technical solution, the foam material is proportioned by the material cylinder 3, and the proportioned foam is stored in the material cylinder 3. The molding box 24 is placed on the base 1 and located below the nozzle 9. The slurry pump 10 is started to pump the foam in the material cylinder 3 along the connecting pipe 11 to the nozzle 9. The foam is sprayed into the molding box 24 through the nozzle 9. By starting the first motor 6, the lead screw 7 is controlled to rotate, so that the slider 8 moves back and forth, driving the nozzle 9 to move back and forth. This makes it easier to spray the foam evenly in the molding box 24 and improve the regularity of the molded sponge.

[0028] Specifically, a second motor 12 is fixedly connected to the top of the material cylinder 3, and the output end of the second motor 12 extends into the interior of the material cylinder 3 and is fixedly connected to a first rotating shaft 13. Several stirring blades 14 are fixedly connected at equal intervals to the outer wall of the first rotating shaft 13.

[0029] Through the above technical solution, while spraying foam into the molding box 24, the second motor 12 is started to drive the first rotating shaft 13 to rotate, causing the stirring blade 14 to rotate and stir the foam in the material cylinder 3, so as to avoid the foam in the material cylinder 3 from settling and stratifying over time, which would affect the quality of the molded sponge.

[0030] Specifically, the bottom of the first rotating shaft 13 passes through the material cylinder 3 and is fixedly connected to a cam 15. The cam 15 is used in conjunction with the forming box 24. A reset assembly is provided on the top of the base 1. The reset assembly includes a fixing plate 16, which is fixedly installed on the top of the base 1. Two sliding shafts 17 are symmetrically slidably connected to the inner wall of the fixing plate 16. One end of each sliding shaft 17 is fixedly connected to a limit block 19, and the other end of each sliding shaft 17 is fixedly connected to a baffle 18. The forming box 24 is located between the baffle 18 and the cam 15. Springs 20 are sleeved on the outer walls of each sliding shaft 17. One end of the spring 20 is fixedly connected to the baffle 18, and the other end of the spring 20 is fixedly connected to the fixing plate 16.

[0031] Through the above technical solution, the first rotating shaft 13 rotates while driving the cam 15 to rotate. When the protruding end of the cam 15 rotates to a position close to the molding box 24, it pushes the molding box 24 to move to one side, causing the baffle 18 to move to one side, which in turn drives the sliding shaft 17 to move to one side and compresses the spring 20. When the protruding end of the cam 15 rotates to a position far away from the molding box 24, the baffle 18 moves back under the action of the spring 20, pushing the molding box 24 to move back. This process repeats itself. As the cam 15 rotates, it causes the molding box 24 to sway left and right, which makes it easier for the foam sprayed inside the molding box 24 to be laid more evenly and improves the flatness of the sponge after molding.

[0032] Specifically, the base 1 has several second rotating shafts 21 fixedly connected at equal intervals inside, and pulleys 22 are rotatably connected to the outer walls of the several second rotating shafts 21; and several rubber rings 23 are fixedly connected to the outer walls of the pulleys 22 at equal intervals.

[0033] Through the above technical solution, the set pulley 22 can reduce the friction between the molding box 24 and the base 1, making it easier for the molding box 24 to swing left and right on the base 1. The set rubber ring 23 can increase the longitudinal friction between the molding box 24 and the pulley 22, preventing the molding box 24 from moving back and forth.

[0034] In use, the foam material is proportioned using the material cylinder 3, and the proportioned foam is stored inside the material cylinder 3. The molding box 24 is placed on the base 1 and positioned below the nozzle 9. The slurry pump 10 is started, and the foam in the material cylinder 3 is pumped along the connecting pipe 11 to the nozzle 9. The foam is then sprayed into the molding box 24 through the nozzle 9. By starting the first motor 6, the lead screw 7 is rotated, causing the slider 8 to move back and forth, which in turn moves the nozzle 9 back and forth. This facilitates the even spraying of the foam into the molding box 24, improving the uniformity of the molded sponge. While spraying the foam into the molding box 24, the second motor 12 is started, driving the first rotating shaft 13 to rotate, causing the stirring blade 14 to rotate and agitate the foam in the material cylinder 3. This prevents the foam from settling and stratifying over time, which would affect the quality of the molded sponge. The first rotating shaft 13 rotates simultaneously with... The cam 15 rotates, and when the protruding end of the cam 15 rotates close to the molding box 24, it pushes the molding box 24 to one side, causing the baffle 18 to move to one side, which in turn drives the sliding shaft 17 to move to one side, compressing the spring 20. When the protruding end of the cam 15 rotates away from the molding box 24, the baffle 18 moves back under the action of the spring 20, pushing the molding box 24 back. This process repeats, and as the cam 15 rotates, the molding box 24 sways left and right, making it easier for the foam sprayed inside the molding box 24 to be laid more evenly, improving the flatness of the foam after molding. The pulley 22 reduces the friction between the molding box 24 and the base 1, making it easier for the molding box 24 to sway left and right on the base 1. The rubber ring 23 increases the longitudinal friction between the molding box 24 and the pulley 22, preventing the molding box 24 from moving back and forth.
