Products made from latex as raw material are called latex products, such as sponges, gloves, toys, hoses, etc. Latex can be divided into natural latex, synthetic latex and artificial latex.

[0019] A method for preparing latex comprises the following steps:

[0020] S1. Sealing:

[0021] When latex preparation is required, the third electric push rod is powered on and started, and the output end of the third electric push rod is extended to push the sealing plug plate into the plug sleeve, so that the plug sleeve blocks the discharge port to achieve sealing of the chassis;

[0022] S2. Filtering:

[0023] When the chassis is in a sealed state, the glue in the glue box is injected into the two feeding pipes through the pipeline, and the glue overflows from the top of the two feeding pipes, so that the glue is injected into the two feeding pipes, and the motor is powered on and started at the same time, the output end of the motor drives the primary gear to rotate, and the primary gear drives the secondary gear to rotate by meshing with the secondary gear, the second electric push rod is powered on and started, and the output end of the second electric push rod is extended to push the rotating rod to deflect, so that the swing gear is meshed with the transmission gear, and the secondary gear drives the swing gear to rotate by synchronous rotation with the swing gear, and the swing gear drives the transmission gear to rotate by meshing with the transmission gear, and the transmission gear drives the two rotating gears to rotate by meshing with the two rotating gears, and the two rotating gears drive the two screen drums to rotate by rotating, so that the two screen drums rotate and filter the injected glue by rotation, so as to filter the impurities in the glue;

[0024] S3, accelerated expansion:

[0025] The heating box is in a vertical state, and the filtered glue liquid falls into the heating box along the hopper. A certain amount of glue liquid is injected into the heating box, and the glue liquid box stops injecting glue into the two feeding pipes. At the same time, the chemical reagent box injects a certain amount of expansion agent into the dripping pipe through the pipeline and then stops. The dripping pipe drips the solidifying liquid into the heating box, and the glue liquid in the heating box expands into a hollow latex block. At the same time, the heating box heats the glue liquid to shorten the expansion time of the glue liquid, so that the glue liquid in the heating box expands faster;

[0026] S4, negative pressure compression:

[0027] When the glue in the heating box has completed expansion, the drip tube is energized to start the negative pressure pump, and the negative pressure pump draws air in the chassis through the pipeline, so that the chassis is in a negative pressure state, and the fourth electric push rod pushes the pawl to deviate from the ratchet wheel, releasing the deflection lock on the heating box, and the output end of the second electric push rod contracts to pull the rotating rod, and the rotating rod drives the swing gear to move, so that the swing gear and the deflection gear are meshed, and the output end of the motor drives the deflection gear to rotate, and the deflection gear drives a shaft rod to rotate, and the shaft rod drives the heating box and another The shaft rotates to make the heating box deflect in the chassis, so that the heating box corresponds to the pressure plate, the motor is powered off and stopped, the output end of the fourth electric push rod contracts to pull the pawl to engage with the shaft, so as to achieve deflection locking of the heating box, and at this time, the two first electric push rods are powered on to start, and the output ends of the two first electric push rods extend to push the pressure plate into the heating box, so that the pressure plate squeezes the expanded hollow latex block in the heating box into a latex compression block, effectively reducing the air contained in the hollow latex block, and achieving negative pressure compression of the hollow latex block;

[0028] S5. Discharging:

[0029] After the negative pressure compression of the hollow latex block is completed, the third electric push rod is powered on first, and the output end of the third electric push rod contracts and pulls the sealing plug plate up to release the sealing plug plate from the discharge port. The output ends of the two first electric push rods extend and retract to pull the pressure plate to pull the pressure plate out of the heating box, and then the fourth electric push rod is powered on. The output end of the fourth electric push rod pushes the pawl to deviate from the ratchet wheel, releases the engagement between the pawl and the ratchet wheel, and facilitates the deflection of the heating box. Then the motor is powered on and started. The motor drives the deflection gear to rotate through the primary gear, the secondary gear and the swing gear. The deflection gear rotates with an axle rod, and then drives the heating box to deflect, so that the heating box is connected to the finished tube. Finally, the two fifth electric push rods are powered on and started. The output ends of the two fifth electric push rods push the push plate to move in the heating box, and the push plate pushes the latex compression block from the heating box into the finished tube, and the latex compression block slides out along the finished tube to realize the discharge of the latex compression block.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. In this scheme, when the heating box needs to be deflected, the output end of the second electric push rod contracts and pulls the rotating rod to deflect, so that the swing gear is meshed with the deflection gear. At this time, the motor is powered on and the output end of the motor drives the first-stage gear to rotate. The first-stage gear drives the second-stage gear to rotate by meshing with the second-stage gear. The second-stage gear shaft drives the swing gear to rotate. The swing gear drives the deflection gear to rotate by meshing with the deflection gear. The deflection gear drives a shaft to rotate, and then the heating box is deflected, so that the heating box is deflected in a negative pressure environment to achieve the ultimate compression of the hollow latex block into a latex compression block, thereby reducing the space volume occupied by the hollow latex block and reducing the transportation cost of the hollow latex block.

[0032] 2. In this scheme, when torque is provided to the two screen drums, the second electric push rod is powered on to start the second electric push rod, which extends to push the rotating rod to deflect, and the rotating rod drives the swing gear to deflect, so that the swing gear is meshed with the transmission gear. At this time, the motor is powered on, and the output end of the motor drives the primary gear to rotate, and the primary gear drives the secondary gear to rotate by meshing with the secondary gear. The secondary gear shaft drives the swing gear to rotate, and the swing gear drives the transmission gear to rotate by meshing with the transmission gear. The transmission gear drives the two rotating gears to rotate by meshing with the two rotating gears. The two rotating gears drive the two screen drums to rotate in the two sleeves, and the filtering effect of the device is improved by the rotation of the two screen drums.

[0033] 3. In this solution, when it is necessary to release the deflection lock of the heating box, the fourth electric push rod is powered on to start the output end of the fourth electric push rod to extend and push the pawl away from the ratchet wheel, thereby releasing the locking connection between the pawl and the ratchet wheel. The pawl is pushed and pulled by the fourth electric push rod to deflect the deflection angle of the locked heating box, thereby ensuring the precise docking of the heating box with the pressing plate, the hopper and the finished tube, preventing the glue from overflowing from the inside and outside of the heating box, causing the inner walls of the chassis to be blocked by the expansion of the glue, thereby reducing the cleaning and maintenance of the equipment due to the expansion of the glue.

[0034] 4. In this solution, when discharging is required, the output end of the third electric push rod contracts to pull the sealing plug plate out of the plug-in sleeve, the limit assembly releases the deflection lock on the heating box, the motor is powered on, and the output end of the motor drives the first-stage gear to rotate. The first-stage gear drives the second-stage gear to rotate by meshing with the second-stage gear. The second-stage gear drives the swing gear to rotate through the rotating shaft. The swing gear drives the heating box to deflect by meshing with the deflection gear. The deflection gear drives an axis rod to rotate, and then drives the heating box to deflect, so that the heating box is connected to the finished tube, which is convenient for introducing the latex compression block in the heating box into the finished tube. The third electric push rod controls whether the chassis is in a sealed state by lifting and moving the sealing plug plate, so as to provide a sealed cavity for latex preparation, reduce dust in the air and reduce the pollution of the latex compression block.

[0035] 5. In this scheme, when the latex hollow block is compressed and the heating box is aligned with the pressing plate, the two first electric push rods are powered on and started, and the output ends of the two first electric push rods push the pressing plate into the heating box, so that the pressing plate compresses the hollow latex block in the heating box and compresses the hollow latex block into a latex compressed block. After the compression of the latex hollow block is completed, the output ends of the two first electric push rods contract to pull the pressing plate out of the heating box. After the latex compressed block is formed, the motor drives the heating box to deflect again, so that the heating box is aligned with the finished tube, and the two fifth electric push rods are powered on and started, and the output ends of the two fifth electric push rods extend to push the pressing plate out of the heating box, so that the pressing plate pushes the latex compressed block in the heating box into the finished tube. The squeezing and pushing components effectively compress the latex hollow block and push out the latex compressed block, thereby realizing rapid compression of the latex hollow block and rapid removal of the latex compressed block.

[0036] 6. In this scheme, when it is necessary to pour glue liquid into the heating box, the glue liquid box is powered on to start the glue liquid box, and the glue liquid box introduces the glue liquid into the two feeding pipes through the pipeline. At the same time, the second electric push rod is powered on to start the second electric push rod, and the output end of the second electric push rod is extended to push the swing gear to engage with the transmission gear. The motor is powered on to start the motor, and the output end of the motor drives the first-stage gear to rotate, and the first-stage gear drives the second-stage gear to rotate. The second-stage gear drives the swing gear to rotate through the rotating shaft, and the engagement of the swing gear with the two rotating gears drives the two rotating gears to rotate. The two rotating gears drive the two sieve drums to rotate. The two sieve drums roll the glue liquid evenly dispersed from the feed pipe through rotation, and disperse the filtered glue liquid on the inner walls of the two sleeves. The glue liquid slides into the hopper along the two sleeves, and the glue liquid in the hopper slides into the heating box, so that the filtered glue liquid is injected into the heating box, thereby improving the purification quality of the glue liquid to be expanded.

The shaft (36) 6) driving the heating box (2) and another shaft (36) to rotate, so that the heating box (2) deflects in the chassis (1), so that the heating box (2) corresponds to the pressure plate (3), the motor (7) is powered off and stopped, the output end of the fourth electric push rod (33) contracts and pulls the ratchet (35) to engage with the shaft (36), so as to achieve deflection locking of the heating box (2), and at this time, power is turned on to start the two first electric push rods (5), the output ends of the two first electric push rods (5) extend to push the pressure plate (3) into the heating box (2), so that the pressure plate (3) squeezes the expanded hollow latex block in the heating box (2) into a latex compression block, effectively reducing the air contained in the hollow latex block, and achieving negative pressure compression of the hollow latex block; S5. Discharging: After the negative pressure compression of the hollow latex block is completed, the third electric push rod (25) is powered on first, and the output end of the third electric push rod (25) contracts to pull the sealing plug plate (38) upward, thereby releasing the sealing plug plate (38) from blocking the discharge port (27). The output ends of the two first electric push rods (5) extend and retract to pull the pressing plate (3), thereby pulling the pressing plate (3) out of the heating box (2). The fourth electric push rod (33) is powered on again, and the output end of the fourth electric push rod (33) pushes the pawl (35) away from the ratchet (34), thereby releasing the meshing of the pawl (35) and the ratchet (34), thereby facilitating the deflection of the heating box (2). The motor (7) is powered on again, and the motor (7) The deflection gear (19) is driven to rotate by the first-stage gear (10), the second-stage gear (11) and the swing gear (13). The deflection gear (19) rotates with a shaft (36), thereby driving the heating box (2) to deflect, so that the heating box (2) and the finished product tube (24) are docked. Finally, the two fifth electric push rods (40) are powered on and started. The output ends of the two fifth electric push rods (40) push the push plate (39) to move in the heating box (2). The push plate (39) pushes the latex compression block from the heating box (2) into the finished product tube (24), and the latex compression block slides out along the finished product tube (24), thereby realizing the discharge of the latex compression block.
