Please refer to fig. 1 to 7, which illustrate an embodiment of a device for extracting entanglement according to the present invention.

In this embodiment, the entanglement extraction device includes: at least one roll shaft which is rotatably and transversely arranged in the shielding shell 200, wherein a plurality of rows of extraction components which are composed of a plurality of sheet-shaped hook tooth sheets 212 are arranged on the outer peripheral surface of the roll shaft, and the hook tooth sheets 212 are annularly and uniformly distributed by taking the roll shaft as an axisymmetric center. The rotation direction of the roll shaft is opposite to the conveying direction of the garbage. As shown in connection with fig. 1, the waste containing the windings enters the interior of the winding extraction device from a rectangular input opening at the top of the winding extraction device in the direction of arrow a. More specifically, in the present embodiment, two parallel rollers, i.e., the roller shaft 211 and the roller shaft 213, are transversely disposed in the shielding shell 200, and the two roller shafts (i.e., the roller shaft 211 and the roller shaft 213) are rotated in the same direction and located at the same horizontal plane. Meanwhile, as shown in fig. 4a and/or 4b, the roller shaft 211 and the roller shaft 213 rotate clockwise in the direction indicated by the arrow D.

In order to simultaneously drive the roller shaft 211 and the roller shaft 213 while maintaining synchronous and same-directional rotation, the entanglement extracting apparatus further includes a driving mechanism 22 in this embodiment. The driving mechanism 22 is a motor, and the motor includes, but is not limited to, a dc motor, an ac motor, a stepper motor, or a servo motor. The roller shaft 211 and the roller shaft 213 extend laterally out of the shield case 200 and are rotated in the shield case 200 by a holder with a built-in bearing. The first sprocket 225 and the second sprocket 227 synchronously driven by the first transmission member 224 are disposed on the same side of the roller shaft 211 as the roller shaft 213, respectively. The second sprocket 227 is coaxially disposed with the third sprocket 223, and the driving mechanism 22 drives the third sprocket 223 via the second transmission 222. The first transmission member 224 and the second transmission member 222 can be belts or chains.

The shielding shell 200 is internally provided with a partition plate 203 for separating and forming an upper channel 202 and a lower channel 206, the partition plate 203 is provided with a strip-shaped hole 2031 for the hook tooth piece 212 to partially extend through the partition plate 203 during the rotation of the roller shaft, the conveying device 205 is arranged at the bottom of the lower channel 206, the hook tooth piece 212 sweeps the top surface of the conveying device 205 during the rotation around the roller shaft, the upper channel 202 is provided with a fan 201, and the fan 201 forms airflow in the upper channel 202 flowing in the same direction as the rotation direction of the hook tooth piece 212. The upper channel 202 and the lower channel 206 are vertically disposed one above the other.

Specifically, the conveying device 205 is a conveyor belt driven by the motor 24, and the garbage without separating the winding object can be driven by the conveying device 205 to make horizontal translation movement from left to right in the direction of arrow a in fig. 2. The output shaft of the motor 24 is coaxially provided with a chain wheel 241, the conveying device 205 is positioned at one side of the shielding shell 200 and is provided with a chain 26, and the chain wheel 26 is connected with the chain wheel 241 through a belt 25, so that the horizontal revolving motion of the conveying device 205 is driven through the rotation of the motor 24, and the horizontal conveying of the garbage is realized.

Specifically, in this embodiment, the fan 201 is an axial flow fan with model SF3-2 and air volume of 3000m³The diameter of the fan blade of the fan 201 is 300mm, and the rotating speed of the fan 201 can be adjusted under the control of a controller (such as a PLC or a single chip microcomputer), so that the flow rate of the airflow moving along the arrow direction C in the upper channel 202 can be adjusted to adapt to the extraction operation of the entanglement with different contents or different properties. The winding object in this embodiment is garbage with a certain length or a certain ductility, such as hair, woven bags, plastic bags, ropes, and the like.

Preferably, the partition 203 is upwardly formed with a boss to compress the cross-sectional area of the upper passage 202 by the boss. By "compressing the cross-sectional area of the upper channel 202", it is meant that the cross-sectional area in the upper channel 202 is reduced by forming a boss, so that the air flow generated horizontally by the fan 201 during operation is blocked by the boss, so that the cross-sectional area formed between the boss and the shielding shell 200 is reduced, thereby increasing the flow velocity of the air flow at the top of the boss, and thus facilitating the separation of the entanglement extracted from the lower channel 206 by the hook teeth piece 212 in the upper channel 202, so that the entanglement is discharged from the entanglement extracting device along the outlet 204 of the upper channel 202 shown in fig. 1. At the same time, the other remaining waste after the extraction of the entanglement exits the entanglement extraction device from the outlet of the lower channel 206 in the direction shown by the arrow B in fig. 1, thereby finally achieving the separation of the entanglement contained in the waste thrown from the rectangular throwing opening.

As shown in fig. 4b, the tooth piece 212 includes a tooth body 2120 connected to the roller shaft (the roller shaft 211 or the roller shaft 213), and a first tooth 2121 and a second tooth 2122 provided in the same direction as the rotation direction of the tooth body 2120, and the first tooth 2121 is provided radially outside the second tooth 2122. During the clockwise rotation of the roller shaft 211 and the roller shaft 213, the protruding directions of the first and second hooking

teeth

2121 and 2122 sequentially arranged in the same direction on the two roller shafts are opposite to the moving direction of the garbage in the lower passage 206, i.e., the first and second hooking

teeth

2121 and 2122 move to the left and the garbage moves to the right.

Of course, referring to fig. 3 and 4a, the hooking tooth piece 212 includes a hooking tooth body 2120 connected to the roller shaft, at least two hooking teeth are provided in the same direction as the rotation direction of the hooking tooth body 2120, and the hooking teeth near the roller shaft (the roller shaft 211 or the roller shaft 213) are curved in the direction of the roller shaft, that is, the hooking tooth body 2120 is provided with a first hooking tooth 2121, a second hooking tooth 2122 and a third hooking tooth 2125, and all three hooking teeth are vertically provided on the hooking tooth body 2120 and radially distributed in the direction of the roller shaft in turn to form a three-turn hooking track by the plurality of hooking tooth pieces 212. Specifically, the second hook 2122 and the third hook 2125 are both bent in the direction of the roller axis. The first hooking tooth 2121 in fig. 4a is identical in structure to the first hooking tooth 2121 in fig. 4b and its function will be described in detail below. The hook tooth piece 212 rotates in the direction of arrow D and hooks the entanglement of different heights in the trash through the first, second, and

third hook teeth

2121, 2122, 2125.

In fig. 4a, the first hooking tooth 2121 is disposed radially outward of the second hooking tooth 2122, and the second hooking tooth 2122 is disposed radially outward of the third hooking tooth 2125. Of course, as the height of the shield case 200 increases, four or more hook teeth may be provided in the radial extending direction of the hook tooth body 2120. In the present embodiment, as shown in fig. 4a and 4b, two or three hooks are disposed on the hook body 2120, so that the entanglement existing at any position in the vertical direction in the garbage conveyed in the lower channel 206 can be extracted, and the extraction effect of the hook piece 212 on the entanglement in the garbage is improved.

Meanwhile, in fig. 4a or 4b, the first hooking tooth 2121, the second hooking tooth 2122 or the third hooking tooth 2125 is tapered and extends in the same direction as the rotation direction of the roller shaft, so that the winding object in the garbage is more effectively hooked by the plurality of hooking teeth and the falling-off and separation of the hooking teeth, particularly the first hooking tooth 2121, from the winding object is realized by the airflow horizontally flowing in the upper passage 202.

Meanwhile, the first hooking tooth 2121 forms an arc edge 21211 whose peripheral contour is tangent to the rotation process of the hooking tooth plate 212, and the second hooking tooth 2122 is bent toward the roll axis. Meanwhile, the tooth body 2120 is provided such that an extension line of a side edge 2124 of one side of the first tooth 2121 and the second tooth 2122 coincides with the axis of the roller shaft, and a side edge of the other side of the tooth body 2120 is arc-shaped to form an arc-shaped side edge 2123, and an extension line of the arc-shaped side edge 2123 is tangent to the outer diameter of the shaft hole 2112 of the assembling roller shaft 211. The width of the finger body 2120 is gradually decreased from the radially outward extending direction of the roller shaft 211, so that the finger body 2120 has sufficient strength to prevent the finger body 2120 from being deformed when a wound object is hooked by the first finger 2121 and the second finger 2122.

Meanwhile, in this embodiment, the phrase "the hook piece 212 sweeps across the top surface of the conveyor 205 during the rotation around the roller shaft" means that, at the moment when the linear side edge 2124 of one hook body 2120 disposed on the roller shaft 211 rotates to the lower passage 206 and is perpendicular to the conveyor 205, the arc-shaped edge 21211 of the first hook 2121 almost fits to the top surface of the conveyor 205 and can form a gap of 1-2 mm, so as to effectively hook the winding in the garbage through the first hook body 2121 and finally pass through the strip-shaped hole 2031 formed on the partition 203 for the hook body 2120 to pass through, and the air flowing to the right in the upper passage 202 blows down and cooperates with the partition 203 to separate the winding wound on the first hook 2121 from the first hook 2121. The separated windings continue to be discharged from the outlet 204 of the upper channel 202 by being blown by a gas flow flowing to the right (see the direction shown by the arrow C in fig. 2).

The linear velocity of the end of the hook blade 212 away from the roller (i.e. the roller 211 or the roller 213) during the rotation of the roller is 3-4 times of the velocity of the air flow of the upper channel 202 which is horizontally flowed by the fan 201. Meanwhile, the thickness of the hook tooth piece 212 is 3-5 mm, the width of the strip-shaped hole 2031 is 2-4 times of the thickness of the hook tooth piece 212, a gap of 30-40 mm is formed between adjacent extraction components, and the gap is a distance along the longitudinal extension direction dimension of the roller shaft 211 or the roller shaft 213.

Referring to fig. 3 and fig. 4a and 4b, in the present embodiment, the outer circumferential surface of the roller shaft 211 is provided with a plurality of rows of extraction assemblies composed of six sheet-shaped hooking tooth pieces 212, the six hooking tooth pieces 212 are axially and annularly arranged on the outer circumferential surface of the roller shaft 211, and when one of the hooking tooth pieces is perpendicular to the partition plate 203, the first hooking teeth 2121 of two adjacent hooking tooth pieces are located above the partition plate 203. Here, the phrase "when one of the hook tooth plates is in a state of being perpendicular to the partition plate 203" means that a radially inward extension of the side edge 2124 is in a state of being perpendicular to the horizontal plane, and the radially inward extension of the side edge 2124 extends beyond the axis 2111 of the pivot shaft of the roller shaft 211 during the rotation thereof. The roller shaft 213 is similar to the roller shaft 211, and will not be described in detail herein.

In this embodiment, the hook body 2120 is provided with the first hook 2121 and the second hook 2122 from inside to outside, so that the hook body 2120 forms two hooking tracks in the rotating process, and can sweep garbage well, so as to ensure that the hook body 2120 is in full contact with the garbage, and accordingly a wound in the garbage can be hooked by the first hook 2121 and the second hook 2122 better.

The above list of details is only for the practical implementation of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.
