[0030] The first opening roller 101 is provided with burrs on the outer side.

[0031] A cutting device is provided in the feed hopper 3, which is composed of an electric roller and a cutter. The electric roller drives the cutter to rotate, thereby cutting the cloth in the feed hopper 3, cutting the longer cloth into small pieces, which is convenient for subsequent loosening processing.

[0032] An electric valve is provided at the lower side of the feed hopper 3. When the loosening operation is being carried out in the outer shell 2, the electric valve is in a closed state. At this time, the cloth in the feed hopper 3 cannot fall into the outer shell 2. Then the worker puts the cloth into the feed hopper 3. At this time, the cloth in the feed hopper 3 is cut by the cutting device. When the cloth in the outer shell 2 is loosened and discharged, the electric valve opens, and then the cut cloth in the feed hopper 3 is poured into the outer shell 2, realizing continuous loosening operation.

[0033] It also includes a fixed rod 106 and a second opening roller 107; four fixed rods 106 are connected to the inner side of the outer shell 2; each fixed rod 106 is fixedly connected to a plurality of second opening rollers 107, and each second opening roller 107 is staggered with the corresponding first opening roller 101.

[0034] The outer side of the second opening roller 107 is also provided with burrs.

[0035] It also includes a second electric turntable 108; the second electric turntable 108 is rotatably connected in the outer shell 2, and the second electric turntable 108 is located at the first electric turntable 4; and a plurality of toggle rods 10801 are arranged on the second electric turntable 108, and the toggle rods 10801 are arranged at intervals from the first opening roller 101.

[0036] The working principle of the above embodiment is as follows:

[0037] by Figure 1 The viewing angle is the reference: the side where the numbered bracket 1 is located is the front side; it should be noted that the external feeding mechanism can be installed above the feed hopper 3, and then the waste cloth can be fed into the feed hopper 3 by the feeding mechanism; then the electric roller in the feed hopper 3 drives the cutter to rotate and cut the cloth in the feed hopper 3, and cuts the longer cloth into small pieces, which is convenient for subsequent loosening; after the cloth is cut into small pieces, the electric valve on the lower side of the feed hopper 3 is opened, and the cut cloth in the feed hopper 3 is poured into the outer shell 2 for loosening;

[0038] When the waste fabric enters the housing 2 from the feed hopper 3, the opening device is started. At this time, the motor 5 drives the rotating shaft 6 to rotate counterclockwise, and then drives the first opening roller 101 to rotate counterclockwise. At this time, the convex thorns on the outer side of the first opening roller 101 will hook the fabric, and then Figure 2 and Figure 3As shown, during the rotation of the first opening roller 101, the waste fabric will be continuously thrown to the inner wall of the shell 2 under the influence of centrifugal force. At this time, the fixed rod 106 is in a stationary state, and the first opening roller 101 will carry the waste fabric and continuously generate friction with the fixed rod 106 and the second opening roller 107 during the continuous rotation, and then tear and loosen the fiber material through high-speed rotation and interaction, making it fluffy; and in this process, the convex thorns arranged on the outer sides of the first opening roller 101 and the second opening roller 107 increase the contact area and friction between the first opening roller 101, the fixed rod 106 and the second opening roller 107 and the waste fabric, thereby enhancing the tearing force and making the waste fabric easier to tear and loosen; after the waste fabric is opened, as shown in FIG. Figure 4 and Figure 5 As shown, the first electric turn plate 4 is controlled to rotate and open toward the outside of the shell 2, and then the second electric turn plate 108 is controlled to rotate and open toward the inside of the shell 2; at this time, the toggle rod 10801 is tilted from the upper back to the lower front; then the motor 5 is controlled to drive the rotating shaft 6 to rotate clockwise, and at this time the first opening roller 101 will carry the opened fiber cloth to rotate counterclockwise. During the rotation, since the toggle rod 10801 is spaced apart from the first opening roller 101, the first opening roller 101 can pass through the toggle rod 10801 during the rotation, and the fiber cloth on the first opening roller 101 will be moved by the toggle rod 108. 01 is intercepted and guided by the toggle rod 10801 which is inclined from the upper rear to the lower front, and is discharged through the discharge port 2002; it should be noted here that when the waste cloth in the feed hopper 3 falls into the outer shell 2, the electric valve on the lower side of the feed hopper 3 is closed. At this time, the cloth in the feed hopper 3 cannot fall into the outer shell 2, and then the feeding mechanism continues to feed the cloth into the feed hopper 3. At this time, the cloth in the feed hopper 3 is cut by the cutting device. When the cloth in the outer shell 2 is loosened and discharged through the discharge port 2002, the electric valve is opened, and the cut cloth in the feed hopper 3 is poured into the outer shell 2, thereby realizing continuous loosening operation.

[0039] Furthermore, when the motor 5 drives the rotating shaft 6 and the first opening roller 101 to rotate, the electric push rod 104 will continuously extend and retract, thereby driving the wedge-shaped roller 105 to slide left and right in the first slide groove 6001. Figure 3As shown: when the wedge-shaped roller 105 moves left and right, the wedge-shaped surface 10501 will continuously contact and squeeze the ball 102; in this process, when the ball 102 moves toward the outside of the shell 2, the sliding part 10101 moves toward the outside of the shell 2, and the compression spring 103 is compressed and contracted; when the ball 102 moves toward the inside of the shell 2, the sliding part 10101 moves toward the inside of the shell 2, and the compression spring 103 stretches and resets, thereby making the first opening roller 101 indirectly expand and retract in the rotating shaft 6 through this method, thereby making the distance between the first opening roller 101 and the fixed rod 106 indirectly expand and shrink, avoiding the problem of waste cloth being blocked in the shell 2 due to the small gap between the first opening roller 101 and the fixed rod 106; at the same time, through the symmetrically arranged wedge-shaped surfaces 10501, the two adjacent first opening rollers in the left and right directions are The opening rollers 101 perform staggered expansion and retraction actions, thereby vibrating and rubbing the stacked waste fabrics, vibrating and rubbing the waste fabrics to loosen them, thereby preventing the waste fabrics from becoming entangled and knotted during the continuous swinging of the first opening roller 101, and rubbing the waste fabrics to loosen them is also beneficial to the subsequent opening operation, so that the opening effect of the fabrics can be more uniform; and in the process of the first opening roller 101 indirectly expanding and retracting in the rotating shaft 6, the first opening roller 101 will continuously produce a hammering effect on the waste fabrics, thereby improving the opening effect of the first opening roller 101; and when the fabrics are in a fiber state after being opened, the first opening roller 101 is indirectly expanded and retracted at this time, and the convex thorns on the surface of the first opening roller 101 are used to hook the fiber fabrics, pull the fiber fabrics, and loosen the fiber fabrics, thereby greatly improving the opening effect of the device on the waste fabrics. Example 2

[0040] On the basis of Example 1, Figure 1 and Figure 4-Figure 7 As shown, it also includes a handle 201, a fixer 202 and an electric cutter 203; the handle 201 is fixedly connected to the left side of the cover plate 7; each fixing rod 106 is fixedly connected to the cover plate 7; and each fixing rod 106 is slidably connected to the outer shell 2; each second opening roller 107 is fixedly connected to a fixer 202 on the side facing the rotating shaft 6; and four electric cutters 203 are slidably connected in each fixer 202.

[0041] The telescopic end of the electric push rod 104 is fixedly connected with an electromagnet, and the electromagnet is a neodymium iron boron magnet. The telescopic end of the electric push rod 104 is magnetically connected to the wedge roller 105. When the worker needs to pull out the fixed rod 106, the magnetic fixation between the electric push rod 104 and the wedge roller 105 is released, which facilitates the worker to pull out the fixed rod 106.

[0042] A limiting portion 2001 is provided on the left side of the housing 2 , and the cover plate 7 is limited by the limiting portion 2001 , so that the worker can push the fixing rod 106 back into the housing 2 to lock the cover plate 7 with the housing 2 .

[0043] The working principle of the above embodiment is as follows:

[0044] After the waste cloth is loosened by the loosening device described in Example 1: the first loosening roller 101 and the second loosening roller 107 will be adhered to more fibers and cotton wool, resulting in more fibers and cotton wool remaining inside the outer shell 2, which are difficult to clean; therefore, after the loosening device has been used for a period of time, the worker can open the first electric turn plate 4, and connect the external air pump to the feed hopper 3, and use the external air pump to blow air into the outer shell 2 to blow the cotton wool remaining in the outer shell 2 out from the first electric turn plate 4, and clean the fibers and cotton wool in the outer shell 2; however, during the continuous rotation of the rotating shaft 6, some cotton wool is easily entangled on the surface of the rotating shaft 6. At this time, it is difficult to blow out the cotton wool entangled on the surface of the rotating shaft 6 by blowing air, so as to prevent the cotton wool from being entangled on the surface of the rotating shaft 6 from being entangled. Figure 4-Figure 7 As shown, the worker can release the connection between the spring buckle on the cover 7 and the hook lock on the shell 2, thereby releasing the connection between the cover 7 and the shell 2. Then the worker starts the fixer 202 and pushes the electric cutter 203 toward the rotating shaft 6, so that the electric cutter 203 contacts the cotton wool wrapped around the surface of the rotating shaft 6. Then the worker grabs the handle 201 and pulls the cover 7, the fixing rod 106 and the second opening roller 107 to the left. In this process, the cotton wool wrapped around the surface of the rotating shaft 6 is cut off and then taken out by the electric cutter 203. At the same time, after the cover 7, the fixing rod 106 and the second opening roller 107 are pulled to the left, the worker can also check whether the parts in the shell 2 are damaged, perform regular maintenance on the opening device, and increase the service life of the equipment.

[0045] On the basis of the above technical effects, the present invention also has the following advantages:

[0046] The electric push rod 104 is magnetically connected to the wedge-shaped roller 105. When a worker wants to pull out the fixing rod 106, the magnetic fixation between the electric push rod 104 and the wedge-shaped roller 105 can be released, so that the worker can pull out the fixing rod 106.

[0047] The cover plate 7 is limited by the limiting portion 2001 , so that the worker can push the fixing rod 106 back into the housing 2 to lock the cover plate 7 with the housing 2 .

[0048] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
