[0021] When a traditional pulverizer pulverizes cotton strips, it can only cut the cotton strips into short strips, but cannot tear the cut short strips apart to form uniform fluffy cotton balls. In the subsequent production and processing, special equipment is needed to perform fluffy processing again, which increases the equipment investment cost.
[0022] In view of this, the utility model provides a tampon shredder, which solves the problem that traditional shredders can only cut the tampon slivers to form short tampon slivers through a cutting device and a splitting device. The equipment first uses a cutting device to cut the tampon slivers into short strips, and then uses a splitting device to tear apart the cut short tampon slivers to form uniform fluffy cotton balls. A single device can complete the operations from cutting to splitting, thereby reducing the investment cost of the equipment.

[0024] In the specific implementation process, it is worth pointing out that the outer wall of the housing 1 is provided with a wall door, through which the sand and stones separated from the cotton balls can be taken out, and the baffle 2 can make the cotton strips fall to the bottom of the housing 1 only at the center of the cutting device 3 and the splitting device 4, so as to prevent the cotton strips from falling to the bottom of the housing 1 without being processed;
[0025] Specifically, when using the tampon crusher, the staff starts the cutting device 3 and the splitting device 4 through an external power supply, and then the worker puts the tampon into the shell 1 from the discharge port on the top of the shell 1. The tampon will first pass through the cutting device 3, and the cutting device 3 will cut the tampon into short strips. The short strips will detach from the cutting device 3 and then fall onto the splitting device 4. The splitting device 4 can tear the cut short tampon apart to form a uniform fluffy cotton ball, and then the cotton ball will fall into the vibration device 6. The sand and stone inside the cotton ball can be separated from the cotton ball by the vibration device 6. At the same time, the worker starts the collecting device 5, and the collecting device 5 can collect the floating cotton fibers generated during cutting and splitting.
[0026] Embodiment 2: By Figure 1 , 2 As can be seen from Figures 3 and 4, the cutting device 3 includes: two first cross bars 301, which are rotatably connected to the inner wall of the housing 1 through bearings; a first servo motor 302, the model of which is ECMA-E11320RS, which is installed on the outer wall of the first fixed plate 7 and is detachably connected to the outer wall of the first cross bar 301 close to the first fixed plate 7; two first gears 303, which are installed on the outer walls of the two first cross bars 301, and the two first gears 303 are meshed and connected; two cutters 304, which are respectively installed on the outer walls of the two first cross bars 301. Installed on the outer wall of the two first cross bars 301; two first gears 303 are provided and meshed and connected.

When the cotton strip passes through the center of the two staggered cutters 304, it will be cut into short cotton strips by the two cutters 304; wherein, the first servo motor 302 can drive the first cross bar 301 to drive the first gear 303 and the first cross bar 301 to rotate;
[0027] In the specific implementation process, it is worth pointing out that two first gears 303 are provided and meshed with each other. When the first gear 303 close to the first fixing plate 7 is rotated under force, the first gear 303 away from the first fixing plate 7 is driven to rotate at the same time. Two cutters 304 are provided, and the two cutters 304 are staggered with each other. When the cotton strip passes through the center of the two staggered cutters 304, it will be cut into short cotton strips by the two cutters 304.
[0028] Specifically, on the basis of the above-mentioned embodiment 1, the staff first starts the first servo motor 302 through an external power supply. After the first servo motor 302 is powered on, it starts to drive the first cross bar 301 to rotate along the inner wall of the shell 1. At the same time, the first gear 303 is affected by the rotation of the first cross bar 301 and starts to rotate. Because two first gears 303 are arranged and meshed with each other, when the first gear 303 close to the side of the first fixed plate 7 is rotated by force, it will drive the first gear 303 away from the side of the first fixed plate 7 to rotate at the same time, so that the two first cross bars 301 can drive the two cutters 304 to rotate. When the cotton strips pass through the center of the two rotating cutters 304, they will be cut into short cotton strips by the two cutters 304.

The outer walls of the two cross rollers 404 are evenly spaced with multiple long needles. When the short cotton strips pass through the centers of the two rotating cross rollers 404, the short cotton strips will be torn apart by the long needles to form a uniform fluffy cotton ball; wherein the second servo motor 402 can drive the second cross bar 401 to drive the second gear 403 and the cross roller 404 to rotate;
[0030] In the specific implementation process, it is worth pointing out that two second gears 403 are provided and meshed with each other. When the second gear 403 close to the second fixed plate 8 is rotated under force, the second gear 403 far from the second fixed plate 8 is driven to rotate at the same time. The outer walls of the two transverse rollers 404 are evenly spaced with multiple long needles. When the short cotton strips pass through the centers of the two rotating transverse rollers 404, the short cotton strips will be torn apart by the long needles to form a uniform fluffy cotton ball.
[0031] Specifically, on the basis of the above-mentioned embodiment 1, the staff first starts the second servo motor 402 through an external power supply. After the second servo motor 402 is powered on, it starts to drive the second cross bar 401 to rotate along the inner wall of the outer shell 1. At the same time, the second gear 403 is affected by the rotation of the second cross bar 401 and starts to rotate. Because two second gears 403 are arranged and meshed with each other, when the second gear 403 close to the side of the second fixed plate 8 is rotated by force, it will drive the second gear 403 away from the side of the second fixed plate 8 to rotate at the same time, and then the two second cross bars 401 can drive the two cross rollers 404 to rotate. When the short cotton strips pass through the center of the two rotating cross rollers 404, they will be torn apart by the two cross rollers 404 to form a uniform fluffy cotton ball.

[0033] In the specific implementation process, it is worth pointing out that the collection box 501 is set at the wall door, and the workers can take out the cotton fiber floating objects through the wall door for unified treatment, and the filter 503 can block the cotton fiber floating objects to prevent the cotton fiber floating objects from entering the fan 502 and causing damage to the fan 502;
[0034] Specifically, on the basis of the above-mentioned first embodiment, the staff first starts the fan 502 through an external power supply. After the fan 502 is powered on, the air inside the collection box 501 will be discharged. At this time, the interior of the collection box 501 is in a negative pressure state. The cotton fiber floating objects generated by the cutting and splitting of the cotton strips inside the shell 1 will be affected by the negative pressure inside the collection box 501, enter the pipe 504 from the collection head 505, and finally be sucked into the interior of the collection box 501, completing the collection operation of the cotton fiber floating objects.
[0035] Embodiment 5: By Figure 1 ,2 As can be seen from Figure 4, the vibration device 6 includes: two slide rails 601, which are respectively installed on both sides of the shell 1; a separation box 602, which is slidably connected to the outer walls of the two slide rails 601; four vertical rods 603, which are respectively installed at the four corners of the bottom of the separation box 602; four vertical pipes 604, which are respectively sleeved on the outer walls of the four vertical rods 603, and are all fixedly connected to the inner wall of the shell 1; four springs 605, which are respectively installed inside the four vertical pipes 604, and are respectively pressed against the bottom of the four vertical rods 603; a vibration motor 606, the model of the vibration motor 606 is: YZO-1, which is installed at the bottom of the separation box 602; the slide rails 601 can limit the movement path of the separation box 602, and when the vibration motor 606 drives the separation box 602 to vibrate , the slide rail 601 can prevent the separation box 602 from being deflected by the vibration, and the slide rail 601 allows the separation box 602 to move up and down only along the outer wall of the slide rail 601 during vibration. The bottom of the separation box 602 is processed with a plurality of equidistant holes. When the sand and stones retained in the cotton ball are separated from the cotton ball, they can fall to the bottom of the shell 1 through these holes. The outer walls of the four vertical rods 603 are all equipped with damping, and then the elastic potential energy generated by the spring 605 can be consumed by the friction between the vertical rod 603 and the vertical tube 604. A protective shell is installed on the outside of the vibration motor 606, and the protective shell can prevent sand and stones from entering the interior of the vibration motor 606; wherein, the vibration motor 606 can drive the separation box 602 and the vertical rod 603 to move along the inner wall of the vertical tube 604 and compress the spring 605;
[0036] In the specific implementation process, it is worth pointing out that the slide rail 601 can limit the movement path of the separation box 602. When the vibration motor 606 drives the separation box 602 to vibrate, the slide rail 601 can prevent the separation box 602 from being offset due to the vibration. The slide rail 601 allows the separation box 602 to move up and down only along the outer wall of the slide rail 601 during vibration. The bottom of the separation box 602 is processed with a plurality of equidistant holes. When the sand and stone retained in the cotton ball are separated from the cotton ball, they can fall to the bottom of the shell 1 through these holes. The outer walls of the four vertical rods 603 are all equipped with damping, and the elastic potential energy generated by the spring 605 can be consumed through the friction between the vertical rod 603 and the vertical tube 604. A protective shell is installed on the outside of the vibration motor 606, and the protective shell can prevent sand and stone from entering the inside of the vibration motor 606.
[0037] Specifically, on the basis of the above-mentioned embodiment 1, when the cotton ball falls into the interior of the separation box 602, the staff starts the vibration motor 606 through an external power supply, and the vibration motor 606 is energized to drive the separation box 602 to vibrate. At the same time, the separation box 602 will drive the vertical rod 603 to move along the inner wall of the vertical tube 604 and compress the spring 605. The spring 605 can make the vertical rod 603 and the separation box 602 reciprocate due to its own elasticity, thereby vibrating the cotton ball inside the separation box 602. The vibration can separate the cotton ball from the sand and gravel remaining inside the cotton ball, and fall into the bottom of the outer shell 1 from the hole processed at the bottom of the separation box 602.
