[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a device for cleaning impurities in a fine cotton opening machine, comprising a cotton opening machine body, an opening mechanism disposed at the upper part of the cotton opening machine body, and an impurity cleaning mechanism disposed below the opening mechanism. The impurity cleaning mechanism includes a dust collection chamber disposed at the bottom of the opening mechanism in the cotton opening machine body, a sliding box disposed on one side of the dust collection chamber, the sliding box contacting the dust collection chamber, a conveying cylinder fixedly connected to the bottom of the inner cavity of the cotton opening machine body and communicating with the outside of the cotton opening machine body, the sliding box being slidably connected to the cotton opening machine body, a vacuum pump fixedly disposed on the side of the sliding box away from the dust collection chamber, a cavity disposed in the sliding box, a dust collection bag detachably connected to the side of the cavity near the dust collection chamber, the dust collection bag being located between the vacuum pump and the dust collection chamber, the input end of the vacuum pump being fixedly connected to the cavity through a conduit, a fixing mechanism for fixing the position of the sliding box disposed in the cotton opening machine body, and a limiting mechanism for fixing the dust collection bag disposed in the sliding box.

[0007] By adopting the above technical solution, a vacuum pump provides power to quickly extract air from the dust collection chamber and the sliding box, creating negative pressure. This generates suction at the top of the dust collection chamber, allowing impurities generated by the cotton opening mechanism to be quickly drawn into the interior of the dust collection chamber, including dust impurities, which are suppressed. The dust is trapped in the dust collection bag, while the impurities are conveyed out of the cotton opener body through the conveyor and enter the external waste bin, thus realizing the impurity cleaning process of the fine cotton opener and effectively improving the impurity removal quality of the cotton opener. The sliding box is slidably connected to the cotton opener body, which means that the sliding box and the dust collection bag set in the sliding box can be pulled out simultaneously, facilitating the maintenance of the dust collection bag. The dust collection bag can be replaced through the limiting mechanism, avoiding clogging or damage of the dust collection bag after long-term use, preventing dust leakage, and making the operation simple and convenient for replacing the dust collection bag.

[0009] By adopting the above technical solution, the through holes set in the dust collection chamber enable the connection between the air chamber and the dust collection chamber. When the vacuum pump is started to provide power, the air in the dust collection chamber and the air chamber is quickly drawn away to form a negative pressure. The design of the filter holes in the baffle can block large particles of impurities in the dust collection chamber, making it convenient for the dust collection bag to collect dust.

[0010] A further feature of this invention is that the fixing mechanism includes two clamping plates slidably connected to the cotton opener body. The two clamping plates are symmetrically arranged along the central axis of the sliding box and are respectively located at both ends of the sliding box. A drive rod is rotatably connected to the cotton opener body. The drive rod is provided with threads of the same pitch but opposite directions. The clamping plates are threadedly connected to the drive rod. The end of the drive rod is fixedly connected to the output end of the drive motor through a coupling. The drive motor is fixedly installed in the cotton opener body. A guide rod is fixedly connected to the cotton opener body. The clamping plates are slidably connected to the guide rod. The guide rod is arranged parallel to the drive rod.

[0011] By adopting the above technical solution, when the sliding box slides into the body of the cotton opener, one side of the sliding box contacts the side of the baffle of the dust collection chamber. Then, the drive motor controls the drive rod to rotate, so that the clamping plates threaded on the drive rod move closer to each other and clamp the two ends of the sliding box to fix the position of the sliding box; the guide rod provides guidance and limit for the movement of the clamping plates.

[0012] A further feature of this invention is as follows: the dust collection bag is fixedly connected to the mounting plate, the mounting plate is embedded in the cavity, and both ends of the mounting plate are provided with protrusions. The cavity of the sliding box has grooves at both ends near the dust collection chamber for the protrusions to be inserted into. The limiting mechanism includes a protrusion on the outer wall of the protrusion, and a fixing seat is provided on the side wall of the sliding box. The protrusion and the fixing seat are on the same straight line in the horizontal direction. The fixing seat has a through hole, and a support shaft is rotatably connected to the through hole. Both ends of the support shaft are fixedly mounted with levers. A U-shaped rod is rotatably connected to the end of the lever away from the support shaft. The lever rotates around the support shaft until it approaches the protrusion, and the U-shaped rod moves away from the protrusion. The lever rotates around the support shaft until it moves away from the protrusion, and the U-shaped rod engages with the protrusion.

[0013] By adopting the above technical solution, when installing the mounting plate and dust collection bag, the sliding box is pulled out of the cotton opener body. A fixed seat is set on the outer wall of the sliding box, and a support shaft is rotatably connected to the fixed seat. A lever is set on the support shaft. The lever is rotatably connected to a U-shaped rod at one end off the support shaft. During operation, the mounting plate is embedded in the sliding box, and the protrusion is embedded in the groove. At this time, the protrusion and the U-shaped rod are on the same straight line in the horizontal direction. Rotate the lever towards the protrusion so that the U-shaped rod is at the front end of the protrusion. Then rotate the lever away from the protrusion to lock the U-shaped rod into the lever, so that the mounting plate and the sliding box are fixed. The installation and replacement of the mounting plate and dust collection bag can be realized through the limiting mechanism.

[0014] A further feature of this invention is that: a material distribution plate is hinged to the dust collection chamber via a rotating rod, a connecting rod is hinged to the material distribution plate, a cam is rotatably connected to the end of the connecting rod away from the material distribution plate, a rotating motor is fixedly connected to the cotton opener body, and the output shaft of the rotating motor passes through the side wall of the dust collection chamber and is fixedly connected to the rotation center of the cam.

[0015] By adopting the above technical solution, when impurities are sucked into the dust collection chamber, the rotating motor controls the cam to rotate, and the cam linkage mechanism causes the material plate to swing up and down around the rotating rod in the dust collection chamber, thereby breaking up the impurities and causing the dust in the impurities to overflow, making it convenient to collect the dust.

[0016] A further feature of this invention is that the dust collection chamber and the cotton opening mechanism are connected through a first channel, and the conveying cylinder and the dust collection chamber are connected through a second channel.

[0017] By adopting the above technical solution, the impurities generated by the cotton opening mechanism enter the dust collection chamber through the first channel. After the dust is collected in the dust collection chamber, the large particles of impurities are conveyed through the second channel into the conveying cylinder and sent out of the cotton opening machine body.

[0019] By adopting the above technical solution, after the impurities enter the conveying cylinder, the conveying motor controls the drive shaft to rotate, causing the spiral blades to convey the impurities.

[0020] A further feature of this invention is that a plurality of blades are uniformly arranged on the transmission shaft along its length.

[0021] By adopting the above technical solution, when the impurities generated by the cotton opener include long fiber impurities, the blades can cut them off during the impurity conveying process, thus preventing long fibers from getting tangled in the spiral blades and affecting the conveying effect.

[0025] The beneficial effects of this utility model are:

[0026] 1. In this utility model, a vacuum pump provides power to quickly extract air from the dust collection chamber and the sliding box, creating a negative pressure. This generates suction at the top of the dust collection chamber, allowing impurities generated by the cotton opening mechanism to be quickly drawn into the interior of the dust collection chamber. This includes dust and other impurities, which are suppressed. The dust is trapped in the dust collection bag, while the impurities are conveyed out of the cotton opening machine body through the conveyor and enter the external waste bin. This process effectively cleans the impurities from the fine cotton opening machine and improves the impurity removal quality of the cotton opening machine.

[0027] 2. In this utility model, the sliding box is slidably connected to the cotton opener body, which means that the sliding box and the dust collection bag set in the sliding box can be pulled out simultaneously, facilitating the maintenance of the dust collection bag.

A [missing information - likely a device or mechanism] is provided in the sliding box 3. The limiting mechanism 8 for fixing the dust collection bag 6 includes a vacuum pump 5 that provides power to quickly extract air from the dust collection chamber 2 and the sliding box 3, creating negative pressure. This generates suction at the top of the dust collection chamber 2, allowing impurities generated by the cotton opening mechanism to be quickly drawn into the interior of the dust collection chamber 2, including dust impurities, which are suppressed. The dust is trapped in the dust collection bag 6, while the impurities are conveyed out of the cotton opening machine body 1 through the conveying cylinder 4 and enter the external waste bin, thus realizing the impurity cleaning process of the fine cotton opening machine and effectively improving the impurity removal quality of the cotton opening machine. In particular, the sliding box 3 is slidably connected to the cotton opening machine body 1, which means that the sliding box 3 and the dust collection bag 6 set in the sliding box 3 can be pulled out simultaneously, facilitating the maintenance of the dust collection bag 6. The limiting mechanism 8 enables the replacement of the dust collection bag 6, preventing the dust collection bag 6 from becoming clogged or damaged after long-term use, avoiding dust leakage. The operation is simple and convenient for replacing the dust collection bag 6.

[0039] Furthermore, the dust collection chamber 2 has an opening 21 on the side near the dust collection bag 6, and a baffle 22 is provided at the opening 21. The baffle 22 has several filter holes 23. The dust collection bag 6 contacts the opening 21, and the cavity 31 is connected to the dust collection chamber 2 through the opening 21. The through holes in the dust collection chamber 2 enable the connection between the cavity 31 and the dust collection chamber 2. When the vacuum pump 5 is started to provide power, the air in the dust collection chamber 2 and the cavity 31 is quickly drawn away to form a negative pressure. The design of the filter holes 23 in the baffle 22 can block large particles of impurities in the dust collection chamber 2, which facilitates the collection of dust in the dust collection bag 6.

[0040] Furthermore, the fixing mechanism 7 includes two clamping plates 71 slidably connected to the cotton opener body 1. The two clamping plates 71 are symmetrically arranged along the central axis of the sliding box 3 and are located at both ends of the sliding box 3.

The guide rod 74 is parallel to the drive rod 72. When the sliding box 3 slides into the cotton opener body 1, one side of the sliding box 3 contacts the side of the baffle 22 of the dust collection chamber 2. Then, the drive motor 73 controls the drive rod 72 to rotate, so that the clamping plates 71 threaded on the drive rod 72 move closer to each other and clamp the two ends of the sliding box 3 to fix the position of the sliding box 3. The guide rod 74 provides guidance and limit for the movement of the clamping plate 71.

[0041] Furthermore, the dust collection bag 6 is fixedly connected to the mounting plate 81, which is embedded in the cavity 31. The mounting plate 81 has protrusions 82 at both ends. The cavity 31 of the sliding box 3 has grooves 83 at both ends near the dust collection chamber 2 for the protrusions 82 to be inserted. The limiting mechanism 8 includes protrusions 84 on the outer wall of the protrusions 82. A fixing seat 85 is provided on the side wall of the sliding box 3. The protrusions 84 and the fixing seat 85 are on the same straight line in the horizontal direction. The fixing seat 85 has a through hole, and a support shaft 86 is rotatably connected within the through hole. A lever 87 is fixedly installed at both ends of the support shaft 86. A U-shaped rod 88 is rotatably connected to the end of the lever 87 away from the support shaft 86. The lever 87 rotates around the support shaft 86 until it is close to the protrusion 84, and the U-shaped rod 88 moves away from the protrusion 84. The lever 87 rotates around the support shaft 86 until it is away from the protrusion 84. When the U-shaped rod 88 is inserted into the protrusion 84, the sliding box 3 is pulled out of the cotton opener body 1 when the mounting plate 81 and the dust collection bag 6 are installed. A fixed seat 85 is provided on the outer wall of the sliding box 3. A support shaft 86 is rotatably connected to the fixed seat 85. A lever 87 is provided on the support shaft 86.

At this time, the protrusion 84 and the U-shaped rod 88 are on the same straight line in the horizontal direction. The lever 87 is rotated towards the protrusion 84 so that the U-shaped rod 88 is located at the front end of the protrusion 84. Then the lever 87 is rotated away from the protrusion 84 so that the U-shaped rod 88 is inserted into the lever 87, thus fixing the mounting plate 81 and the sliding box 3. The installation and replacement of the mounting plate 81 and the dust collection bag 6 are realized through the limiting mechanism 8.

[0042] Furthermore, a material distribution plate 9 is hinged to the dust collection chamber 2 via a rotating rod, and a connecting rod 10 is hinged to the material distribution plate 9.

A central rod is fixedly connected to the rotation center of the cam 11. The output end of the rotating motor 12 is fixedly connected to the central rod via a coupling. When impurities are sucked into the dust collection chamber 2, the rotating motor 12 controls the cam 11 to rotate. Through the cam 11 linkage mechanism, the material distribution plate 9 swings up and down around the rotating rod in the dust collection chamber 2, thereby dispersing the impurities and causing the dust in the impurities to overflow, making it convenient to collect the dust.

[0043] Furthermore, the dust collection chamber 2 is connected to the cotton opening mechanism through the first channel 13, and the conveying cylinder 4 is connected to the dust collection chamber 2 through the second channel 14. The impurities generated by the cotton opening mechanism enter the dust collection chamber 2 through the first channel 13.

After the impurities enter the conveying cylinder 4, the conveying motor 18 controls the drive shaft 15 to rotate, so that the spiral blade 16 conveys the impurities. Several blades 17 are evenly arranged on the drive shaft 15 along its length. When the impurities generated by the cotton opener include long fiber impurities, the blades 17 can cut them during the process of conveying the impurities, so as to prevent long fibers from getting tangled in the spiral blade 16 and affecting the conveying effect.

[0045] Furthermore, a switch door 19 is hinged to the side wall of the cotton opener body 1. The switch door 19 is located on the side of the sliding box 3 away from the dust collection chamber 2.

[0047] Working principle of this utility model:

[0048] Those skilled in the art use a hopper to feed raw materials into the inner cavity of the cotton opener body 1, which then enters the cotton opener mechanism for processing. The processed cotton bundles are then conveyed out of the cotton opener body 1 via a conveying mechanism. Impurities fall freely, and a vacuum pump 5 provides power to quickly extract air from the dust collection chamber 2 and the sliding box 3, creating a negative pressure. This causes suction to be generated at the top of the dust collection chamber 2, allowing impurities generated by the cotton opener mechanism to be quickly drawn into the interior of the dust collection chamber 2. This process suppresses impurities such as dust, which are trapped in the dust collection bag 6. The impurities are conveyed out of the cotton opener body 1 via a conveying cylinder 4 and enter an external waste bin, thus completing the impurity cleaning process of the fine cotton opener.

[0049] After prolonged use, open the switch panel and pull out the sliding box 3 from the cotton opener body 1. A fixed seat 85 is provided on the outer wall of the sliding box 3. A support shaft 86 is rotatably connected to the fixed seat 85. A lever 87 is provided on the support shaft 86. A U-shaped rod 88 is rotatably connected to one end of the lever 87 that is offset from the support shaft 86. During operation, the mounting plate 81 is embedded into the sliding box 3, and the protrusion 82 is embedded into the groove 83. At this time, the protrusion 84 and the U-shaped rod 88 are on the same straight line in the horizontal direction. Rotate the lever 87 towards the protrusion 84 so that the U-shaped rod 88 is at the front end of the protrusion 84. Then rotate the lever 87 away from the protrusion 84 to lock the U-shaped rod 88 into the lever 87, thereby fixing the mounting plate 81 and the sliding box 3, and realizing the installation and replacement of the mounting plate 81 and the dust collection bag 6.
