Description

Technical Field

[0001] This utility model belongs to the technical field of latex foaming machines, specifically a latex foaming control device. Background Technology

[0002] Latex is a milky liquid extracted from the trunk of rubber trees. Latex has excellent elasticity and wear resistance, making it widely used in various fields. For example, it can be used to make pillows and mattresses. The general manufacturing process for pillows and mattresses currently involves two main steps. First, the raw materials undergo pretreatment, including deammoniation of natural latex, accelerator blending and grinding, and latex mixing. Then, the latex enters the mattress and pillow production line, which includes foaming, molding, vulcanization, demolding, washing and dehydration, and drying.

[0003] The principle of foaming is to mix natural latex, foaming agent and other raw materials together and put them into foaming equipment. Foaming is carried out by stirring and injecting air. Before foaming, a coagulant needs to be added to ensure that the foam solidifies in 3-5 minutes. The purpose is to solidify the bubbles and prevent them from dissipating.

[0004] The problem with existing technology is that when air is introduced into the raw material, the air does not disperse easily and it is difficult to achieve uniform contact with the raw material.

[0005] Therefore, this utility model provides a latex foaming control device. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A latex foaming control device of this utility model includes a foaming tank; a cover plate is hinged to the top of the foaming tank, a motor is fixedly connected to the top of the cover plate, a main shaft is fixedly connected to the bottom of the motor, the main shaft is rotatably connected to the cover plate, a through pipe is fixedly connected to the bottom of the main shaft, multiple extension pipes are connected to the outside of the through pipe, two air outlets are connected to both sides of the extension pipes, a waterproof and breathable membrane is provided at the end of the air outlet, the waterproof and breathable membrane is fixedly connected to the extension pipe, the through pipe is rotatably connected to the foaming tank, and an air inlet pipe is connected to the bottom of the through pipe and fixedly connected to the foaming tank. During operation, first, the latex raw material is placed in the foaming tank and the cover is closed. Then, air is introduced into the air inlet pipe. The gas enters the connecting pipe through the air inlet pipe, then passes through the extension pipe, and finally is released from the air outlet. It acts on the latex raw material in the foaming tank. Starting the motor will drive the main shaft and connecting pipe to rotate, which in turn causes the extension pipe to rotate inside the foaming tank. The gas released from the air outlet can be evenly mixed with the latex raw material. The rotation of the extension pipe will also drive the latex raw material to stir, ensuring the uniformity of the foaming process. Through the rotation of the main shaft and connecting pipe driven by the motor, as well as the air transmission through the extension pipe and air outlet, the air and latex raw material can be brought into rapid contact, thereby making the latex raw material foam more uniformly.

[0008] Preferably, a fixing frame is fixedly connected to the middle of the air outlet, and a spring is fixedly connected to the middle of the fixing frame. A stop block is fixedly connected to one end of the spring. The stop block is slidably connected to the air outlet. During operation, the gas released from the air outlet can push the stop block, creating a gap between it and the air outlet, thus allowing the gas to flow out smoothly. The sliding action of the stop block within the air outlet helps to compress the latex material, effectively reducing the possibility of the latex material clogging the air outlet and avoiding problems such as obstructed airflow and uneven mixing of the latex material. By reasonably configuring the stop block and the waterproof and breathable membrane, the air outlet can be further protected, preventing the latex material from clogging and ensuring that air can be smoothly discharged from the air outlet, thereby improving foaming efficiency.

[0009] Preferably, crossbars are fixedly connected to both sides of the main shaft, and a rotating rod is rotatably connected to the bottom of the crossbars. A stirring plate is fixedly connected to the outside of the rotating rod. During operation, the rotation of the main shaft drives the crossbars to rotate, and the rotation of the crossbars drives the rotating rod and the stirring plate to agitate the latex raw material. This process can break up the latex raw material, making it more fully integrated with the air, thereby accelerating the foaming rate. When the stirring plate comes into contact with the latex raw material, it will cause the rotating rod to rotate, realizing comprehensive agitation of the latex raw material in the foaming tank, ensuring that the latex raw material can foam more quickly and efficiently.

[0010] Preferably, a heating element is provided on the outer side of the stirring plate. The heating element is fixedly connected to the foaming tank. During operation, in order to ensure the uniformity of the latex during the foaming process, the heating element controls the temperature inside the foaming tank to reduce the gelation or precipitation of the latex raw materials and avoid obstruction of the stirring process.

[0011] Preferably, the foaming tank is provided with an insulation layer on the outside, and the insulation layer is fixedly connected to the foaming tank. During operation, the insulation layer keeps the inside of the foaming tank warm to slow down the rapid loss of heat and prevent the latex raw material from gelling or settling.

[0012] Preferably, a sealing gasket is fixedly connected to the top of the foaming tank. The sealing gasket fits against the cover plate. During operation, the sealing gasket is used to fill and seal the gaps between the foaming tanks to ensure the airtightness of the inside of the foaming tank, thereby reducing contamination by impurities.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The latex foaming control device of this utility model achieves rapid contact between air and latex raw materials by driving the rotation of the main shaft and the through pipe by a motor, and by transmitting air through the extension pipe and the air outlet, thereby making the latex raw materials foam more uniformly.

[0015] 2. The latex foaming control device of this utility model, by reasonably configuring the baffles and waterproof and breathable membrane, can further protect the air outlet, prevent the latex raw material from being blocked, and ensure that the air outlet can smoothly discharge air, thereby improving the foaming efficiency.

During operation, the first... First, the latex raw material is placed in the foaming tank 1 and the cover plate 11 is closed. Then, air is introduced into the air inlet pipe 18. The gas enters the connecting pipe 14 through the air inlet pipe 18, then passes through the extension pipe 15, and finally is released from the air outlet 16, acting on the latex raw material in the foaming tank 1. The motor 12 drives the main shaft 13 and the connecting pipe 14 to rotate, thereby causing the extension pipe 15 to rotate in the foaming tank 1. The gas released from the air outlet 16 can be evenly mixed with the latex raw material. The rotation of the extension pipe 15 also drives the latex raw material to stir, ensuring the uniformity of the foaming process. Through the rotation of the main shaft 13 and the connecting pipe 14 driven by the motor 12, and the air transmission through the extension pipe 15 and the air outlet 16, the air and the latex raw material come into rapid contact, thereby making the foaming of the latex raw material more uniform.

[0025] like Figures 1 to 4As shown, a fixing frame 2 is fixedly connected to the middle of the air outlet 16, and a spring 21 is fixedly connected to the middle of the fixing frame 2. A stop block 22 is fixedly connected to one end of the spring 21. The stop block 22 is slidably connected to the air outlet 16. During operation, the gas released from the air outlet 16 can push the stop block 22, creating a gap between it and the air outlet 16, thus allowing the gas to flow out smoothly. The sliding action of the stop block 22 within the air outlet 16 helps to compress the latex raw material, effectively reducing the possibility of the latex raw material clogging the air outlet 16, and avoiding problems such as obstructed airflow and uneven mixing of the latex raw material. By reasonably configuring the stop block 22 and the waterproof and breathable membrane 17, the air outlet 16 can be further protected to prevent the latex raw material from clogging, ensuring that the air outlet 16 can smoothly discharge air, thereby improving the foaming efficiency.

[0026] like Figures 1 to 4 As shown, crossbars 3 are fixedly connected to both sides of the main shaft 13. A rotating rod 31 is rotatably connected to the bottom of the crossbars 3. A stirring plate 32 is fixedly connected to the outside of the rotating rod 31. During operation, the rotation of the main shaft 13 drives the crossbars 3 to rotate, and the rotation of the crossbars 3 drives the rotating rod 31 and the stirring plate 32 to stir the latex raw material. This process can break up the latex raw material, making it more fully integrated with the air, thereby accelerating the foaming rate. When the stirring plate 32 comes into contact with the latex raw material, it will cause the rotating rod 31 to rotate, realizing the comprehensive stirring of the latex raw material in the foaming tank 1, ensuring that the latex raw material can foam more quickly and efficiently.

[0027] like Figures 1 to 5 As shown, a heating element 4 is provided on the outside of the stirring plate 32. The heating element 4 is fixedly connected to the foaming tank 1. During operation, in order to ensure the uniformity of the latex during the foaming process, the heating element 4 controls the temperature inside the foaming tank 1 to reduce the gelation or precipitation of the latex raw materials and avoid obstruction of the stirring process.

[0028] like Figures 1 to 5 As shown, the foaming tank 1 is provided with an insulation layer 5 on the outside. The insulation layer 5 is fixedly connected to the foaming tank 1. During operation, the insulation layer 5 insulates the inside of the foaming tank 1 to slow down the rapid loss of heat and prevent the latex raw material from gelling or precipitating.

[0029] like Figures 1 to 5 As shown, a sealing gasket 6 is fixedly connected to the top of the foaming tank 1. The sealing gasket 6 is in contact with the cover plate 11. During operation, the sealing gasket 6 is used to fill and seal the gaps between the foaming tanks 1 to ensure the airtightness of the inside of the foaming tank 1, thereby reducing the contamination of impurities.

[0030] Working principle: First, the latex raw material is placed in the foaming tank 1 and the cover plate 11 is closed. Then, air is introduced into the air inlet pipe 18. The gas enters the connecting pipe 14 through the air inlet pipe 18, then passes through the extension pipe 15, and finally is released from the air outlet 16, acting on the latex raw material in the foaming tank 1. The starting motor 12 drives the main shaft 13 and the connecting pipe 14 to rotate, thereby causing the extension pipe 15 to rotate inside the foaming tank 1. The gas released from the air outlet 16 can be evenly mixed with the latex raw material. The rotation of the extension pipe 15 also drives the latex raw material to stir, ensuring the uniformity of the foaming process. Through the rotation of the main shaft 13 and the connecting pipe 14 driven by the motor 12, and the air transmission through the extension pipe 15 and the air outlet 16, the air and the latex raw material are brought into rapid contact, making the foaming of the latex raw material more uniform. The gas released from the air outlet 16 can push the baffle 22, forming a gap between it and the air outlet 16, thereby allowing the gas to flow out smoothly. The sliding action of the baffle 22 within the vent 16 helps to compress the latex material, effectively reducing the possibility of the latex material clogging the vent 16 and avoiding problems such as obstructed airflow and uneven mixing of the latex material. By properly configuring the baffle 22 and the waterproof and breathable membrane 17, the vent 16 can be further protected, preventing latex material blockage and ensuring that air can be smoothly discharged from the vent 16, thereby improving foaming efficiency. The rotation of the main shaft 13 drives the crossbar 3 to rotate accordingly, which in turn drives the rotating rod 31 and the stirring plate 32 to agitate the latex material. This process disperses the latex material, allowing it to integrate more fully with the air, thus accelerating the foaming rate. When the stirring plate 32 comes into contact with the latex raw material, it causes the rotating rod 31 to rotate, thereby achieving comprehensive stirring of the latex raw material in the foaming tank 1. This ensures that the latex raw material can foam more quickly and efficiently. During the foaming process, in order to ensure the uniformity of the latex, the heating element 4 controls the temperature inside the foaming tank 1 to reduce the gelation or precipitation of the latex raw material and avoid obstruction of the stirring process. The insulation layer 5 insulates the inside of the foaming tank 1 to slow down the rapid loss of heat and prevent the latex raw material from gelling or settling. The sealing gasket 6 is used to fill and seal the gaps between the foaming tanks 1 to ensure the airtightness of the inside of the foaming tank 1, thereby reducing the contamination of impurities.
