Description

Technical Field

[0001] The utility model relates to the technical field of latex foaming machines, in particular to a latex foaming machine. Background Art

[0002] When producing latex products, the latex raw materials need to be foamed, so a latex foaming machine is needed. The existing Chinese utility model patent with announcement number "CN212684521U" and patent name "A latex foaming machine for latex pillow production" discloses a latex foaming machine. By arranging air jet holes on the air supply stirring blades, air can be sprayed into the interior through the air jet holes when the latex raw materials are stirred, so that the latex raw materials can be fully combined with the air. However, this technical solution has the following problems: the air supply stirring blades serve as stirring blades, which rotate at high speed during operation, and the air jet holes are arranged on them. During the high-speed rotation, the latex raw materials will enter the air supply stirring blades from the air jet holes. When the air supply stirring blades stop rotating, the raw materials will further enter the air supply stirring blades, thereby causing the air supply stirring blades to be blocked, affecting the jet effect. In order to solve this problem, a new latex foaming machine is needed. Utility Model Content

[0026] Furthermore, a fixing rod 6 is provided at the connecting hole, and the fixing rod 6 is rotatably connected to the rotating rod 3. An airway connected to the airway of the rotating rod 3 is provided in the fixing rod 6. A plurality of through holes 7 are provided on the fixing rod 6, and the through holes 7 are connected to the airways in the fixing rod 6. Both ends of the elastic membrane 5 are fixedly connected to the fixing rod 6, and the elastic membrane 5 covers all the through holes 7.

[0027] Furthermore, the air outlet holes on the elastic membrane 5 and the through holes 7 on the fixing rod 6 are arranged in a staggered manner and do not overlap, so as to prevent the latex material from directly entering the through holes 7 of the fixing rod 6 when exerting pressure on the air outlet holes.

[0028] Furthermore, when the airway is not inflated, the elastic membrane 5 fits the fixed rod 6. The elastic membrane 5 can well cover the perforation 7 when not inflated, and the rod body of the fixed rod 6 can well support the elastic membrane 5 to prevent the latex material from entering the elastic membrane 5.

[0029] Furthermore, the driving mechanism includes a mounting frame fixedly connected to the top of the foaming tube 1 , a motor 8 fixedly connected to the mounting frame, and the motor 8 is transmission-connected to the rotating rod 3 .

[0030] Furthermore, a notch connected to the internal airway is provided on the side of the top of the rotating rod 3, and a connecting sleeve 9 is rotatably connected to the outer side of the rotating rod 3. The connecting sleeve 9 is fixedly connected to the foaming tube 1, and an air inlet is opened on the side of the connecting sleeve 9, which is connected to the air source through a hose.

[0031] Furthermore, a support frame is provided at the bottom of the foaming tube 1 .

[0032] Furthermore, a discharge port 11 is provided at the bottom of the foaming tube 1 , and a discharge pipe 12 is connected to the discharge port 11 .

[0034] Furthermore, the control valve body 13 is an electrically controlled valve body.

[0035] The working principle of this embodiment is as follows:

[0036] During the working process, the motor 8 controls the rotating rod 3 to rotate, thereby driving the stirring rod 4 to rotate, so as to stir and foam the latex raw material. In addition, the air source will inflate the rotating rod 3, and the gas will enter the fixed rod 6 through the air, and then be discharged from the perforation 7 of the fixed rod 6, and then be discharged from the air outlet hole of the elastic membrane 5, so that the air enters the foaming tube 1 and combines with the latex raw material.

[0037] When there is no pressure in the airway, the elastic membrane 5 is in a natural state. In this state, the air outlet is in a closed state, and the latex raw material cannot enter the elastic membrane 5; when the air source is working and gas is introduced into the airway, a larger air pressure enters the fixed rod 6 through the air outlet, and enters the elastic membrane 5 from the perforation 7, inflating the elastic membrane 5, and the gas is then ejected through the air outlet. Since the gas has a certain pressure when it comes out, the latex raw material cannot enter the elastic membrane 5 through the air outlet. The elasticity of the elastic membrane 5 prevents the latex raw material from entering the elastic membrane 5 through the air outlet.
