Abstract
Description
Technical Field
[0001] This application relates to the field of cotton bag production equipment, and in particular to a foaming device for cotton bag production. Background Technology
[0002] A pillow (cotton pouch) generally consists of a pillowcase and filling. In the past, people would fill cloth bags with materials such as cotton and plant particles to form a shape similar to a "cotton pouch"; therefore, pillows were also called cotton pouches.
[0003] In existing technologies, latex pillows (latex pouches) are favored by some consumers due to their high elasticity and breathability. The manufacturing process involves mixing natural latex with additives (such as vulcanizing agents and activators), and using mechanical stirring to evenly mix air into the latex liquid, forming a rich and delicate foam structure. Subsequently, the foamy latex liquid undergoes high-temperature vulcanization to form the raw material for the latex pillow (latex pouch).
[0004] In the prior art, the latex liquid is placed in a foaming container, and gas is mixed into the latex liquid by mechanical stirring; however, the latex liquid in the upper and lower regions of the foaming container has low fluidity, which affects the uniformity of the latex liquid foaming. Utility Model Content
[0005] To improve the uniformity of latex foaming, this application provides a foaming device for cotton bag production.
[0006] This application provides a foaming device for cotton bag production, which adopts the following technical solution:
[0007] A foaming device for producing cotton bales includes a foaming tank, a stirring assembly, and a vertical extrusion assembly. The foaming tank includes a tank body and a lid that fit together.

The main body of the stirring assembly is disposed in the stirring chamber and is used to stir and shear the latex liquid to mix it with air. The drive end of the vertical extrusion assembly is disposed in the extrusion channel and reciprocates vertically to extrude the latex liquid within the extrusion channel.
[0008] By adopting the above technical solution, when the stirring component is used to stir and shear the latex liquid so that the air mixes with the latex liquid, the driving end of the vertical extrusion component moves vertically to promote the vertical flow of the latex liquid in the stirring chamber, thereby improving the uniformity of latex liquid stirring and foaming.
[0009] Optionally, the vertical extrusion assembly includes a linear reciprocating drive and an extrusion head. The linear reciprocating drive is disposed on the can cover, and the extrusion head is disposed at the drive end of the linear reciprocating drive and in the extrusion channel. The linear reciprocating drive drives the extrusion head to move vertically reciprocally.
[0010] By adopting the above technical solution, the linear reciprocating drive unit drives the extruder head to move vertically, thereby promoting the vertical flow of latex liquid in the mixing chamber and improving the uniformity of latex liquid mixing and foaming.

The second connecting port is located on the side of the first connecting port near the tank cover. The liquid level of the latex in the stirring chamber is higher than that of the second connecting port. The latex passes through the second connecting port and enters the extrusion channel. The extrusion head vertically extrudes and pushes the latex flowing into the extrusion channel.
[0014] By adopting the above technical solution, the tank body is provided with a second connecting port, which allows the latex liquid in the middle layer of the mixing chamber to enter the extrusion channel; when the extrusion head moves vertically, the extrusion head can extrude the original middle layer of latex liquid to the upper or lower layer of latex liquid in the mixing chamber; thereby further promoting the upper and lower flow of latex liquid in the mixing chamber and improving the uniformity of latex liquid foaming.
[0015] Optionally, the extrusion channel has an upper opening, the height of which is higher than the liquid level of the latex in the mixing chamber; when the extrusion head moves vertically upward, the extrusion head drives the latex entering the extrusion channel to flow upward, and the latex flows back into the mixing chamber through the upper opening.
[0016] By adopting the above technical solution, the extrusion pusher drives the latex liquid in the extrusion channel to flow upward, and the latex liquid flows back into the stirring chamber through the upper opening, so as to further promote the mutual conversion of different layers of latex liquid.

[0019] Optionally, the extrusion head is provided with a second guide surface on the side near the linear reciprocating drive member, and the distance from the second guide surface to the stirring assembly increases in the vertical upward direction.
[0020] By adopting the above technical solution, a second guide surface is provided on the upper part of the extrusion pusher, so that when the extrusion pusher moves vertically upward, the latex liquid in the extrusion pusher channel can flow back to the mixing chamber.

[0022] By adopting the above technical solution, the drive motor drives the stirring blade to rotate. The stirring blade is used to stir and shear the latex liquid so that the air mixes with the latex liquid, causing the latex liquid to foam into a foam structure.

Detailed Implementation
[0031] The following is in conjunction with the appendix Figure 1 -3 provides further detailed description of this application.
[0032] This application discloses a foaming device for producing cotton bales. (Refer to...) Figure 1 The foaming device for cotton bag production includes a foaming tank 1, a stirring assembly 2, and a vertical extrusion assembly 3.
[0033] Reference Figure 1 and Figure 2 The foaming tank 1 includes a tank body 11 and a tank lid 12 that fit together. The tank body 11 is provided with a stirring chamber 111 and an extrusion channel 112, which is vertically arranged. In this embodiment, the extrusion channels 112 are symmetrically arranged on both sides of the stirring chamber 111; correspondingly, two vertical extrusion components 3 are also provided. The bottom of the foaming tank 1 is provided with a first connecting port 13, which connects the stirring chamber 111 and the extrusion channel 112.
[0034] Reference Figure 1 The tank lid 12 is equipped with a main material inlet pipe 15, an auxiliary material inlet pipe 16, and an air inlet pipe 17, which are connected to the mixing chamber 111. Latex liquid is fed into the mixing chamber 111 through the main material inlet pipe 15, and other additives (vulcanizing agents, activators, etc.) are fed into the mixing chamber 111 through the auxiliary material inlet pipe 16. The tank body 11 is equipped with a discharge pipe 14, which is connected to the mixing chamber 111. The latex liquid and additives are mixed in the mixing chamber, and air is introduced to foam the mixture into a foam structure. The pre-foamed latex liquid is then discharged from the foaming device through the discharge pipe 14.
[0035] Reference Figure 2The stirring chamber 111 is used to contain the latex liquid, and the main body of the stirring assembly 2 is disposed in the stirring chamber 111. The stirring assembly 2 includes a drive motor 21, a stirring shaft 22, and a stirring blade 23. The drive motor 21 is disposed on the tank cover 12, the stirring shaft 22 is vertically disposed in the stirring chamber 111, the stirring shaft 22 is disposed on the drive motor 21, and the stirring blade 23 is fixedly disposed on the stirring shaft 22. The stirring assembly 2 is used to stir and shear the latex liquid so that air mixes with the latex liquid, causing the latex liquid to foam into a foam-like structure. In this embodiment, the stirring blade 23 is a turbine-type stirring blade 23.
[0036] Reference Figure 1 and Figure 3 The tank body 11 also includes a second connecting port 18 and an upper opening 19, which connect the stirring chamber 111 and the extrusion channel 112. The second connecting port 18 is located on the side of the first connecting port 13 near the tank cover 12, and the upper opening 19 is located at the top of the extrusion channel 112. In this embodiment, the liquid level of the latex in the stirring chamber 111 is higher than that of the second connecting port 18. The latex passes through the second connecting port 18 and enters the extrusion channel 112. The extrusion head 32 vertically extrudes the latex flowing into the extrusion channel 112. The height of the upper opening 19 is higher than that of the liquid level of the latex in the stirring chamber 111. When the extrusion head 32 moves vertically upward, it drives the latex entering the extrusion channel 112 to flow upward, and the latex flows back into the stirring chamber 111 through the opening.
[0037] Reference Figure 1 and Figure 3 The vertical extrusion assembly 3 includes a linear reciprocating drive 31 and an extrusion head 32. The linear reciprocating drive is mounted on the can cover 12, and the extrusion head 32 is located at the drive end of the linear reciprocating drive 31 and is positioned within the extrusion channel 112. The linear reciprocating drive 31 drives the extrusion head 32 to reciprocate vertically, thereby extruding the latex liquid within the extrusion channel 112. This causes latex liquid at different heights within the mixing chamber 111 to flow into the extrusion channel 112. The vertically moving extrusion head 32 changes the vertical height of the latex liquid within the extrusion channel 112, allowing the latex liquid in the extrusion channel 112 to flow back into the mixing chamber 111. In this embodiment, the extrusion head 32 has a first chamber 321 inside; that is, the extrusion head 32 is hollow to reduce its weight and facilitate vertical movement.
[0038] Reference Figure 1 and Figure 3 That is, by using the vertical extrusion component 3, the latex liquid in the upper and lower regions of the mixing chamber 111 flows to each other; when the mixing component 2 stirs the latex liquid, it can improve the uniformity of latex liquid contact with air in different regions, thereby improving the uniformity of latex liquid foaming.
[0039] Reference Figure 1 and Figure 3 In this embodiment, the extrusion head 32 has a first guide surface 33 on the side away from the linear reciprocating drive member 31, and a second guide surface 34 on the side of the extrusion head 32 closer to the linear reciprocating drive member 31. Along the vertically upward direction, the distance between the first guide surface 33 and the stirring assembly 2 decreases, while the distance between the second guide surface 34 and the stirring assembly 2 increases.
[0040] The implementation principle of a foaming device for cotton bag production according to an embodiment of this application is as follows:
[0041] Reference Figure 1 and Figure 3 When the height of the extrusion head 32 is higher than the second connecting port 18, the latex liquid in the middle layer of the mixing chamber 111 will pass through the second connecting port 18 and enter the extrusion channel 112. As the extrusion head 32 moves downward, it will push the original middle layer of latex liquid downward, causing it to pass through the first connecting port 13 and flow back to the bottom of the mixing chamber 111; thus, the original middle layer of latex liquid flows to the bottom layer area of the latex liquid. At the same time, the first guide surface 33 of the extrusion head 32 is inclined, which helps to push the latex liquid in the extrusion channel 112 into the mixing chamber 111.
[0042] Reference Figure 1 and Figure 3 When the height of the extrusion head 32 is higher than the second connecting port 18, the latex liquid in the middle layer of the mixing chamber 111 will pass through the second connecting port 18 and enter the extrusion channel 112. When the extrusion head 32 moves upward, it will push the original middle layer of latex liquid upward, so that the original middle layer of latex liquid will flow back into the mixing chamber 111 through the upper opening 19 of the extrusion channel 112; thus, the original middle layer of latex liquid will mix with the upper layer of latex liquid, thereby achieving the mixing of different layers of latex liquid and improving the uniformity of latex liquid foaming.
[0043] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
