The discharge conveyor 310 is used to output the opened wool. The opened wool falls onto the discharge conveyor 310 under the action of gravity and is output to the outside of the cabinet 1 through the discharge port 3 along with the discharge conveyor 310.

As shown in fig. 2, the anti-wind assembly is used to remove the wool wound on the roller pins 520 of the upper and lower rollers 410 and 510. The anti-wind assembly includes a movable spike 610, a connecting rod 620, a telescopic cylinder 630 and a baffle box 640.

The two movable spikes 610 are respectively and vertically connected with the end parts of the connecting rod 620, and the two movable spikes 610 are positioned on the same side of the connecting rod 620 and are arranged in parallel, the connecting rod 620 is used for fixing one ends of the two movable spikes 610, and the two movable spikes 610 are connected with the telescopic cylinder 630 through the connecting rod 620. The connection rod 620 is pushed by the expansion and contraction of the expansion and contraction cylinder 630, and the movable spike 610 is pushed to expand and contract. When the anti-winding assembly works, the movable spike 610 is pushed out through the telescopic cylinder 630, and the wool wound between the roller spikes 520 is cleaned. When the anti-winding assembly is not in operation, the movable spike 610 is retracted by the telescopic cylinder 630, and the retracted movable spike 610 cooperates with the roller spike 520 on the upper row roller 410 and/or the lower row roller 510 to jointly open wool.

Thereby allowing the effective length of the roller spike 520 for pulling and tearing open the wool to be increased, facilitating efficient opening of the wool.

Wherein, the movable spike 610 is positioned in the gap between two adjacent roller spikes 520, so as to avoid the collision between the movable spike 610 and the roller spike 520 in the opening process or when the wound wool is removed, and promote the stable operation of the opening device.

The anti-winding assemblies are uniformly distributed with a plurality of groups along the axial direction of the upper row roller shaft 410 or the lower row roller shaft 510 so as to ensure that the wound wool can be completely cleaned. The movable spike 610 is horizontally disposed and is adjacent to one of the upper and lower ends of the upper row roller shaft 410 or the lower row roller shaft 510 in the radial direction. Rule for setting positions of anti-winding groups: the tip direction of the movable spike 610 is opposite to the rotation direction of the upper row roller 410 or the lower row roller 510, so that when the upper row roller 410 or the lower row roller 510 is set to rotate, the wool wound between the roller spikes 520 can be transferred to the movable spike 610, the working efficiency of the anti-winding component is accelerated, the opening efficiency of the wool opening device is improved, and the quality of the wool is further improved.

According to the technical scheme, the wool is efficiently opened, the upper row roller shaft and the lower row roller shaft are arranged, and the roller shaft spike is arranged on the upper row roller shaft and the lower row roller shaft, so that the wool is pulled by the roller shaft spike in the rotation process, the clustered wool is scattered, and the wool opening effect is achieved. Through setting up antiwind subassembly, in time reject winding wool between roller spike on upper roller and the lower roller, and then make roller spike open the effective use length of during operation and increase, help pulling the wool, and then be favorable to the high-efficient of wool to open.

The connecting rod 620, a portion of the movable spike 610 adjacent to the connecting rod 620 and the telescoping cylinder 630 are located within the gear box 640.

Specifically, the lower bottom surface of the baffle box 640 is connected to the inner wall of the casing 1, and plays a role in fixing the baffle box 640. The upper bottom surface of the baffle box 640 opposite to the lower bottom surface is provided with a through hole for the movable spike 610 to pass through, and the arrangement has the beneficial effects that: when the anti-winding assembly rejects the wool wound between the roller shaft spikes 520, along with the rotation of the upper roller shaft 410 and/or the lower roller shaft 510, the wool wound between the roller shaft spikes 520 is gradually transferred to the movable spike 610, the wool is wound on the movable spike 610 at the outer length of the baffle box 640, at this time, the telescopic cylinder 630 is controlled to shrink to drive the movable spike 610 to move towards the telescopic cylinder 630, and the upper bottom surface of the baffle box 640 blocks the wool on the movable spike 610, so that the purpose of unloading the wool on the movable spike 610 is achieved. The lower bottom surface of the baffle box 640 is a surface where a longer side of an isosceles trapezoid is located, and the upper bottom surface of the baffle box 640 is a surface where a shorter side of the isosceles trapezoid is located and a side parallel to the lower bottom surface.

As the upper row roller 410 and/or the lower row roller 510 continue to rotate, the roller pins 520 again cooperate with the movable pins 610 to pull and tear apart the wool removed from the movable pins 610 along with the wool to be opened fed from the feed inlet 2.

Placing the telescoping cylinder 630 in the baffle box 640 also can avoid the influence of wool on the telescoping cylinder 630. Meanwhile, the baffle box 640 is of an isosceles trapezoid structure, so that wool can smoothly slide down after falling onto the outer surface of the baffle box 640, the wool can be prevented from gathering outside the baffle box 640, and the wool is prevented from remaining in the machine shell 1.

As shown in fig. 1, alternatively, one ends of the upper and lower roller shafts 410 and 510 are respectively connected to the inner wall of the casing 1, the other end of the upper roller shaft 410 is connected to a motor 430 disposed outside the casing 1, and the other end of the lower roller shaft 510 passes through the side wall of the casing 1 and is connected to one end of the upper roller shaft 410 adjacent to the motor 430 through a conveyor 530.

Specifically, the upper row roller 410 and the lower row roller 510 are disposed in parallel up and down in the casing 1, and are powered by the motor 430, so as to drive the upper row roller 410 to rotate, and the upper row roller 410 drives the conveyor 530 to drive the lower row roller 510 to rotate, thereby opening the wool.

Alternatively, the distance between the roller pins 520 of the side of the upper row roller 410 adjacent to the lower row roller 510 is less than 0.

Specifically, the distance between the roller spikes 520 is less than 0, which is helpful to improve the degree of pulling wool, so that the loosening degree of the wool is improved, and further, the opening efficiency of the wool is improved.

Further, the maximum overlapping length between the roller pins 520 of the side of the upper row roller 410 and the lower row roller 510 is less than 1/2 of the length of the roller pins 520. If the upper and lower roller pins 520 overlap more, the resistance of the upper and lower roller shafts 410 and 510 to rotate increases, and a motor with higher power is required to drive the upper and lower roller shafts 410 and 510 to rotate, resulting in energy waste.

Alternatively, the tip of the movable spike 610 is spaced apart from the upper row roller 410 or the lower row roller 510 in the vertical direction by 2-5cm.

Specifically, if the distance between the tip of the movable spike 610 and the upper row roller 410 or the lower row roller 510 is too small, the movable spike 610 is likely to collide with the upper row roller 410 or the lower row roller 510, and if the distance is too large, the effect of eliminating the wool wound around the roller spike 520 is not achieved.

Optionally, a baffle 301 is connected to the top of the outlet 3.

Specifically, since the opened wool has a certain degree of bulk, the baffle 301 can prevent the wool from being fluffy and difficult to collect and accumulating at the discharge port 3 when the opened wool is discharged, and thus the wool opening device can be operated more stably and smoothly.

As shown in fig. 1, optionally, the outfeed conveyor 310 has a mesh structure, and a vibrator 320 is provided on the outfeed conveyor 310.

Specifically, during wool opening, impurities such as weeds and dust in the wool may fall down as the wool becomes fluffy. The discharging conveyor belt 310 is of a net structure, and impurities fall down and pass through the net discharging conveyor belt 310 to the bottom of the machine shell 1, so that the effect of removing impurities in wool is achieved. Meanwhile, the vibrator 320 is arranged on the discharging conveyor belt 310, the discharging conveyor belt 310 is vibrated, and then the falling of impurities is accelerated, so that the quality of the opened wool is improved.

Optionally, a trash outlet 7 is formed at the bottom of the casing 1, and the trash outlet 7 is connected with a trash collecting groove 710.

Specifically, the impurity discharging port 7 is tapered with a wide upper portion and a narrow lower portion, so that the impurities can fall down conveniently, and the impurity collecting tank 710 is used for collecting the impurities.

The technical scheme of the application is illustrated in detail by specific examples.

Wool to be opened from the feed inlet 2 is brought into the opening mechanism along with the rotation of the upper roller 410, and simultaneously, the wool is pulled under the action of the roller spike 520 along with the rotation of the upper roller 410 and the lower roller 510, so that the clustered wool is loosened, and the wool opening effect is achieved. The opened wool falls onto the discharge conveyor 310 under the action of gravity and is output to the outside of the cabinet 1 through the discharge port 3 along with the discharge conveyor 310. Impurities fall down and pass through the meshed discharging conveyor belt 310 in the opening process, are collected into the impurity collecting tank 710 through the impurity discharging port 7, and are conveyed to a treatment station for waste treatment after the opening is finished.

In the wool opening process, the opening mechanism needs to be subjected to an anti-winding effect at fixed time. When the wool wound by the upper row roller shaft 410 and/or the lower row roller shaft 510 needs to be removed, the telescopic cylinder 630 is controlled to extend, the movable spike 610 is pushed out to one end of the tip of the movable spike 610, which is close to the upper end and the lower end of the upper row roller shaft 410 and/or the lower row roller shaft 510, simultaneously the upper row roller shaft 410 and/or the lower row roller shaft 510 continue to rotate, the wool wound among the roller shaft spikes 520 is penetrated by the movable spike 610 in the rotating process and gradually transferred onto the movable spike 610 along with the rotation, the telescopic cylinder 630 is controlled to shrink, and then the movable spike 610 is also retracted, and the upper row roller shaft 410 and/or the lower row roller shaft 510 continuously rotate and act together with the movable spike 610, so that the wool on the movable spike 610 and the wool from the feed inlet 2 are pulled and loosened, and the purpose of removing the wool wound among the roller shaft spikes 520 is achieved. And further the effective use length of the roller shaft nail thorn 520 for opening work is increased, which is helpful for the efficient opening of wool.

Rule for setting positions of anti-winding groups: the tip direction of the movable spike 610 is opposite to the rotation direction of the upper row roller 410 or the lower row roller 510, so that when the upper row roller 410 or the lower row roller 510 is set to rotate, the wool wound between the roller spikes 520 can be transferred to the movable spike 610, the working efficiency of the anti-winding component is accelerated, the opening efficiency of the wool opening device is improved, and the quality of the wool is further improved.
