[0049] Adopting the above scheme: the second driving member 78 comprises an electric motor, a gear and a connecting frame, a pair of gears are driven to rotate by the electric motor, and the eccentric wheels 77 are fixedly connected with the second driving member 78, so as to be rotated. Figure 9 The rotation direction of the double-shaft cutter 79 is indicated by an arc arrow, and the exhaust direction of the air holes below the plug body 710 is indicated by a Figure 9The vertical downward arrow is shown. A pair of springs and pull rods are arranged in the clamping plate 74, the clamping plate 74 and the fixed end of the telescopic rod 73 are rotationally connected, the middle part of the clamping plate 74 and the pull rod are rotationally connected, and the other end of the pull rod and the telescopic end of the telescopic rod 73 are rotationally connected; the telescopic end and the fixed end of the telescopic rod 73 are connected through the spring; when the telescopic rod 73 is retracted, a pair of pull rods can be pulled to clamp the clamping plate 74, and when the telescopic rod 73 is released, the clamping plate 74 is opened by the spring, and the next clamping is waited. After the woven bag is cleaned, the electric push rod 71 pushes the vertical plate 72 to drive the telescopic rod 73 and the clamping woven bag to reach the upper part of the feeding port 4, and the cleaned woven bag is discharged into the crusher 3 for crushing, without manual discharging and feeding. At this time, the staff can continue to put the next woven bag, and so on, so as to improve the efficiency of woven bag cleaning and transportation. Figure 4 As shown, the collection box is connected with the crusher 3, which is convenient for collecting and processing impurities.

[0050] The working principle and use process of the present application are as follows:

[0051] Before the woven bag is crushed, the internal dust and impurities need to be removed. The staff first opens the door of the machine body 1, then puts the woven bag into the end of the upper support rod 54 and the lower support plate 64, and at this time the bottom of the woven bag abuts against the end of the brush 63. The electric motor 52 is started to drive the bidirectional screw rod 53 to rotate, and the bidirectional screw rod 53 is used to open the upper support rod 54 and the lower support plate 64 outward, and the woven bag is opened. Then rotate the knob 56, drive the convex strip 58 to rotate through the inner rotating rod 510, and the convex strip 58 extrudes the sliding block 511 to slide to the edge of the upper support rod 54, and then pushes the steel nail 59 out of the outer wall of the upper support rod 54 through the sliding block 511, and the steel nail 59 is inserted into the woven bag to position it. At this time, the first magnet 513 on the inner rotating rod 510 is attracted to the second magnet 514 on the side surface of the inner cavity of the upper support rod 54, and the current position is fixed. The woven bag is opened in the inner triangle through the two upper support rods 54 and the lower support plate 64, and the top two sides are positioned by the steel nails 59 to prevent disengagement, which is convenient for the next cleaning process.

[0052] When the woven bag is opened and positioned, the side door of the machine body 1 is closed to make the woven bag in a closed space, the first driving member 66 is started to drive the threaded rod 69 to rotate, and then the rotating shaft 62 is driven to rotate synchronously through the transmission gear and the belt 65. When the rotating shaft 62 rotates, the outer arc frame 61 can be driven to rotate, the bristles 63 on the outer wall of the arc frame 61 are constantly brushed on the inner surface of the woven bag, and the bristles 63 at the end of the arc frame 61 can constantly brush the end joint of the woven bag to brush out the dust hidden in the joint. Moreover, the middle part of the arc frame 61 is hollow, so that the dust flying upward during brushing can fall into the lower part through the middle space, and most of the dust during brushing is collected in the woven bag, reducing the dust in the machine body 1. When the threaded rod 69 rotates, the threaded sleeve 610 can be driven to move axially along the threaded rod 69, and the cutter 611 installed at the bottom of the threaded sleeve 610 moves axially, cutting the woven bag along the side wall thereof. At this time, the dust brushed by the bristles 63 constantly falls through the cut and enters the dust collecting port 2 for collection, effectively avoiding dust and reducing environmental dust. After the side of the woven bag is completely cut, the internal dust is also brushed off, the electric control knob 56 is reversely rotated to make the inner rotating rod 510 drive the convex strip 58 to reset, the spring pushes the sliding block 511 to always adhere to the outer wall of the convex strip 58, and then the steel nail 59 is retracted into the nail hole 55 to release the positioning of the woven bag. At this time, the first magnet 513 is magnetically positioned with the second magnet 514 in the inner cavity of the upper supporting rod 54. The dust cleaning and cutting and impurity removing processes of the woven bag are carried out at the same time, effectively saving the cleaning time.

[0053] When the woven bag is cleaned and the positioning is released, the telescopic rod 73 is started to abut the clamping plate 74 against the outer surface of the woven bag. When the telescopic rod 73 is retracted, the pair of pull rods of the clamping plate 74 close the clamping plate 74 on both sides to clamp the woven bag. At the same time, the electric push rod 71 drives the woven bag to pass through the rubber strip curtain 75. At this time, the electric push rod 71 drives the vertical plate 72 to drive the telescopic rod 73 and the clamped woven bag to reach the upper part of the feeding port 4 to discharge. Then, the cleaned woven bag is put into the crusher 3 through the release of the clamping plate 74 for crushing. Manual discharging and feeding are not required. At this time, the staff can continue to put the next woven bag, and so on, to improve the cleaning and transportation efficiency of the woven bag and promote the efficiency of the overall crushing process of the woven bag.

[0054] When the woven bag is cleaned, it is clamped by the clamping plate 74; under the drive of the electric push rod 71, the woven bag moves transversely to the inlet 4 through the rubber strip curtain 75; at this time, the pair of pull rods of the clamping plate 74 is released through the extension rod 73, and the clamping plate is opened by the spring assistance, and the clamping plate 74 is kept open to release the woven bag, and at this time the woven bag is straightened into a long strip and slides down along the inclined surface of the inclined plate 76 to the middle. Start the second driving part 78 to drive the eccentric wheels 77 on both sides to rotate, the eccentric wheels 77 are driven by the shaft of the second driving part 78 to make reciprocating eccentric rotation, the outer wall sleeve of the shell 716 moves synchronously, because the extension slide column 715 is connected with the sleeve plate 714 through the slide sleeve at the top of the shell 716, and the extension slide column 715 is sleeved with the fixedly installed sleeve plate 714, therefore the extension slide column 715 can limit the shell 716, so that it does not deviate when following the movement of the eccentric wheel 77, to ensure that the counterattack knife 711 can keep intermittent cutting state, the counterattack knife 711 on both sides continuously centers and connects to produce transverse shearing force, and high-speed shearing action is carried out, at this time the woven bag continuously slides down along the inclined surface of the inclined plate 76 to the middle, therefore the counterattack knife 711 can assist in cutting the woven bag to shorten it, so that when the woven bag reaches the double-shaft knife 79 for tearing and crushing, the efficiency of crushing can be enhanced. At the same time, when the eccentric wheel 77 makes reciprocating eccentric rotation, it can also indirectly extrude the pressure piston column 712 to move downward, because the end of the pressure piston column 712 is elastically connected with the plug body 710, therefore the pressure piston column 712 can automatically reset after being pressed downward. And under the cooperation of the one-way valve 713, the one-way valve 713 can only intake air downward of the plug body 710, therefore when the piston column 712 is pressed downward, the one-way valve 713 is closed, the original gas in the plug body 710 can be quickly extruded through the lower air hole and rushed out, reaches the edge of the knife edge of the double-shaft knife 79, and blows off the impurities in the gap. When the piston column 712 moves upward to reset, the one-way valve 713 is opened to cooperate with the corresponding air suction, avoids the plug body 710 from sucking air reversely, and ensures that the airflow impact direction is always downward, tangent to the rotation direction of the double-shaft knife 79, more easily blows off the impurities, and the blown-off impurities can enter the collecting box from the two side edges, while the woven bag crushed by the double-shaft knife 79 falls from the middle of the double-shaft knife 79 to the outlet of the crusher 3, which can avoid the impurities mixed with the cut woven bag.
