[0022] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention, rather than to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0023] like Figure 1 and Figure 2As shown, the present invention provides a loosening device, which is used to loosen the compacted bagged powder material. The loosening device includes two rows of conveying rollers 1 and two driving devices 2. An extrusion area is provided between the two rows of conveying rollers 1 located at the top and bottom, respectively. Each driving device 2 corresponds to a row of conveying rollers 1, and the driving device 2 can drive the corresponding row of conveying rollers 1 to rotate circumferentially. An extrusion component 11 protruding outward is provided on the peripheral wall of the conveying roller 1. When the bagged powder material is located in the extrusion area, the bagged powder material is conveyed forward based on the rotation of the conveying roller 1, and the extrusion components 11 of the two rows of conveying rollers 1 at the top and bottom respectively squeeze the upper and lower surfaces of the bagged powder material to loosen the compacted bagged powder material.

[0024] Specifically, the number of the upper row of conveying rollers 1 is multiple, for example, the number of the upper conveying rollers 1 is 6; the number of the lower row of conveying rollers 1 is multiple, for example, the number of the lower conveying rollers 1 is 16. Of course, the number of the upper and lower conveying rollers 1 can also be the same, and the present invention does not limit the number of the upper and lower conveying rollers 1. The axis of the upper conveying roller 1 is located on the same plane, and the axis of the lower conveying roller 1 is also located on the same plane, so that the bagged powder material can move smoothly. Preferably, the upper conveying roller 1 and the lower conveying roller 1 are both extended in the horizontal direction so that the bagged powder material can be conveyed in the horizontal direction. Of course, the upper conveying roller 1 and the lower conveying roller 1 can also be extended in the direction of inclination upward or inclination downward, so that the bagged powder material can be conveyed in the direction of inclination upward or inclination downward, and the present invention does not limit this. The upper driving device 2 can drive all the upper conveying rollers 1 to rotate by means of a gear structure or a chain transmission structure; similarly, the lower driving device 2 can drive all the lower conveying rollers 1 to rotate by means of a gear structure or a chain transmission structure, and the present invention does not limit this. The driving device 2 is preferably a motor. The pressing component 11 may be configured as an outward protrusion, such as an outward protruding bump, so that the pressing component 11 can apply a pressing force to the bagged powder material.

[0025] In this embodiment, when the bagged powder material is located in the extrusion area, the upper row of conveying rollers 1 and the lower row of conveying rollers 1 enable the bagged powder material to be conveyed forward during the circumferential rotation. And during the conveying process, the extrusion components 11 of the upper conveying rollers 1 continuously squeeze the upward side of the bagged powder material, and the extrusion components 11 of the lower conveying rollers 1 continuously squeeze the downward side of the bagged powder material, and under the continuous extrusion of each extrusion component 11, the compacted powder material can gradually become loose. Therefore, the extrusion processing method of the loosening device can replace the processing methods such as manual beating or manual pressing, avoiding high-intensity manual labor, and also helping to improve the efficiency of loosening processing.

[0026] In some embodiments of the present invention, the overall height of the upper row of conveying rollers 1 is adjustable; and / or the overall height of the lower row of conveying rollers 1 is adjustable.

[0027] In this embodiment, the height of the upper row of conveyor rollers 1 and / or the overall height of the lower row of conveyor rollers 1 are adjustable, so that the height of the extrusion area is adjustable. The volume specifications of different types or batches of bagged powder materials may be different, so different bagged powder materials placed on the lower row of conveyor rollers 1 may have different thicknesses. The height of the upper row of conveyor rollers 1 and / or the overall height of the lower row of conveyor rollers 1 are adjusted so that the height of the extrusion area can adapt to various bagged powder materials.

[0028] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the loosening device includes a first connecting frame 3 and two rows of support columns 4, the upper row of conveying rollers 1 is rotatably mounted on the first connecting frame 3, and the two rows of support columns 4 are respectively located on both sides of the axial direction of the upper row of conveying rollers 1. A cavity is provided inside the support column 4, and a vertically extending adjustment rod 41 is provided in the cavity. The top of the adjustment rod 41 is provided with an operating portion 411 extending from the top of the support rod; two vertically spaced connecting portions 412 are arranged around the adjustment rod 41, and the outer wall of the connecting portion 412 is threadedly connected to the side wall of the cavity. A slider 42 is movably sleeved on the adjustment rod 41, and the slider 42 is located between the two connecting portions 412. The upper and lower ends of the slider 42 are respectively connected to the two connecting portions 412 through compression springs 43. A vertically extending long hole is provided on the side of the support column 4 facing the extrusion area, and the slider 42 is connected to the first connecting frame 3 through the long hole. Wherein, based on the rotation of the operating portion 411, the first connecting frame 3 and the upper row of conveying rollers 1 rise or fall with the adjustment rod 41.

[0029] Specifically, the number of support columns 4 in each row can be 1, 2 or more, which is not limited by the present invention. The support column 4 can be a tubular component or a C-shaped component, etc., which is not limited by the present invention. An internal thread is provided on the inner wall of the support column 4, and an external thread is provided on the outer wall of the connecting portion 412, and the length of the internal thread is much longer than the length of the external thread, so that the adjustment rod 41 has a certain range of up and down movement. The operating portion 411 can be a block-shaped or rod-shaped component, etc., to facilitate the operator to rotate the adjustment rod 41. The compression spring 43 can be sleeved on the adjustment rod 41 to limit the displacement of the compression spring 43. Since the slider 42 is movably sleeved on the adjustment rod 41, the compression spring 43 at the bottom supports the slider 42, and the compression spring 43 at the top pulls up the slider 42, so that the slider 42 remains in the middle section of the adjustment rod 41.

[0030] In this embodiment, when it is necessary to increase the height of the upper row of conveying rollers 1, the operating part 411 of the adjusting rod 41 is rotated to move the adjusting rod 41 upward along the threaded structure, and the adjusting rod 41 will drive the first connecting frame 3 and the upper row of conveying rollers 1 to move upward, thereby increasing the spacing between the upper and lower rows of conveying rollers 1, that is, increasing the height of the extrusion space, so that the extrusion space can adapt to large-sized bagged powder materials. When it is necessary to reduce the height of the upper row of conveying rollers 1, the operating part 411 of the adjusting rod 41 is rotated to move the adjusting rod 41 downward along the threaded structure, and the adjusting rod 41 will drive the first connecting frame 3 and the upper row of conveying rollers 1 to move downward, thereby reducing the spacing between the upper and lower rows of conveying rollers 1, that is, reducing the height of the extrusion space, so that the extrusion space can adapt to small-sized bagged powder materials. In addition, sometimes the adjustment of the adjusting part may be excessive, so that the height of the extrusion area is slightly less than the preset height, but the setting of the compression spring 43 will automatically adapt the upper row of conveying rollers 1 to the thickness or height of the bagged powder materials.

[0031] In some embodiments, the first connecting frame 3 can be configured as a square frame. For example, the first connecting frame 3 includes two connecting rods in the width direction and two connecting rods in the length direction. The upper row of conveyor rollers 1 are all installed in the first connecting frame 3, and all the upper conveyor rollers 1 are spaced apart along the length direction of the first connecting frame 3. Both ends of all conveyor rollers 1 are rotatably connected to the two connecting rods in the width direction of the first connecting frame 3 respectively. The driving device 2 can be connected to each upper conveyor roller 1 through a gear structure installed on the first connecting frame 3.

[0032] like Figure 1 As shown, in some embodiments of the present invention, the loosening device also includes a second connecting frame 5 and a supporting frame 6, the lower row of conveying rollers 1 are rotatably mounted on the second connecting frame 5, the second connecting frame 5 is mounted on the top of the supporting frame 6, the driving device 2 for driving the lower row of conveying rollers 1 is mounted below the second connecting frame 5, and the support column 4 is mounted on the top of the second connecting frame 5.

[0033] Specifically, both ends of the lower conveying roller 1 are rotatably connected to the second connecting frame 5, and the top of the conveying roller 1 is not lower than the top of the second connecting frame 5, so as to facilitate the conveying of the bagged powder material. Installing the driving device 2 below the second connecting frame 5 can prevent the driving device 2 from interfering with the conveying of the bagged powder material.

[0034] In some embodiments, the second connecting frame 5 can be configured as a square frame-shaped connecting frame. For example, the second connecting frame 5 includes two connecting rods in the width direction and two connecting rods in the length direction. The lower row of conveyor rollers 1 are all installed in the second connecting frame 5, and all the lower conveyor rollers 1 are spaced apart along the length direction of the second connecting frame 5. Both ends of all conveyor rollers 1 are rotatably connected to the two connecting rods in the width direction of the second connecting frame 5 respectively. The driving device 2 can be connected to each lower conveyor roller 1 through a gear structure installed on the second connecting frame 5.

[0035] In some embodiments, the second connecting frame 5 and the supporting frame 6 can be connected by a plurality of liftable cylinders, so that the overall height of the second connecting frame 5 (including the conveying roller 1 installed on the second connecting frame 5) can be adjusted, thereby adjusting the height of the extrusion area between the first connecting frame 3 and the second connecting frame 5. Of course, the second connecting frame 5 and the supporting frame 6 can also be fixed by welding.

[0036] In some embodiments, the first connecting frame 3 and the second connecting frame 5 can be connected by multiple liftable cylinders so that the overall height of the first connecting frame 3 (including the conveying roller 1 installed on the first connecting frame 3) can be adjusted, thereby adjusting the height of the extrusion area between the first connecting frame 3 and the second connecting frame 5.

[0037] like Figure 1 As shown, in some embodiments of the present invention, a plurality of running wheels 61 are provided at the bottom of the support frame 6 so that the loosening device can move to a corresponding processing position. Preferably, the running wheel 61 can be a universal wheel with a locking device.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, two guide plates 51 are provided on the top of the second connecting frame 5 , the two guide plates 51 are spaced apart along the axial direction of the conveying roller 1 , and the extrusion area is located between the two guide plates 51 .

[0039] Specifically, during the conveying process of the bagged powder material, the guide plate 51 can guide the bagged powder material to be conveyed along a preset path or direction, and the guide plate 51 can also prevent the bagged powder material from falling.

[0040] like Figure 1As shown, in some embodiments of the present invention, in the lower row of conveying rollers 1, the two conveying rollers 1 located in the middle are connected to the driving device 2 corresponding to the row as active rollers by chain transmission. The two active rollers are the first active roller and the second active roller, and the first active roller is located in front of the second active roller. Among the first active roller and all conveying rollers 1 located in front of the first active roller, every two adjacent conveying rollers 1 are connected by chain transmission; among the second active roller and all conveying rollers 1 located behind the second active roller, every two adjacent conveying rollers 1 are connected by chain transmission.

[0041] Specifically, two sprockets are provided on the lower conveying roller 1 . The two sprockets are spaced apart and distributed along the axial direction of the conveying roller 1 , and the sprockets are coaxial with the conveying roller 1 .

[0042] In this embodiment, the lower row of conveying rollers 1 is actually divided into two conveying roller groups. The first active roller and the conveying roller 1 in front of it are the first group, and the second active roller and the conveying roller 1 behind it are the second group. In the first group, every two adjacent conveying rollers 1 are connected by a chain, and the conveying roller 1 as the first active roller is also connected to the driving device 2 by a chain. In the second group, every two adjacent conveying rollers 1 are connected by a chain, and the conveying roller 1 as the second active roller is also connected to the driving device 2 by a chain. Therefore, in the two conveying roller groups, (in their respective transmission directions) the upper conveying roller 1 drives the lower conveying roller 1, and each active roller can drive a small part of the conveying roller 1, thereby ensuring the overall transmission efficiency of the lower row of conveying rollers 1.

[0043] like Figure 4 As shown, in some embodiments of the present invention, the pressing component 11 extends along the axial direction of the conveying roller 1 .

[0044] Specifically, the extrusion component 11 has a longer length, so that the extrusion surface of the extrusion component 11 is larger, which helps the extrusion component 11 to fully extrude the bagged powder material. Preferably, the extrusion component 11 is a strip-shaped protrusion.

[0045] like Figure 4 As shown, in some embodiments of the present invention, there are multiple extrusion components 11 , and all the extrusion components 11 are distributed at intervals along the circumference of the conveying roller 1 .

[0046] Specifically, increasing the number of squeezing components 11 can increase the number of squeezing times of the bagged powder material during the rotation of the conveying roller 1, which helps the squeezing components 11 to fully squeeze the bagged powder material. Preferably, the squeezing components 11 and the conveying roller 1 can be integrally formed.

[0047] In some embodiments, the extrusion component 11 is configured as a convex block integrally formed with the conveying roller 1, and there are multiple extrusion components 11, which are distributed in multiple rows at intervals on the periphery of the conveying roller 1. In some embodiments, the conveying roller 1 can be a square roller, and the corners on the square roller are the extrusion components 11.

[0048] In some embodiments, the pressing component 11 may also be a block-shaped component that can be detachably mounted on the conveying roller 1 .

[0049] In some embodiments of the present invention, a counter for counting the number of bagged powder materials is also provided on the top of the second connecting frame 5, so as to facilitate on-site personnel to count or check the number of bagged powder materials. It should be noted that the counter is a common electronic device in the art, and the present invention will not repeat its structure and principle.

[0050] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. The above are only preferred implementation methods of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the present invention to other occasions without improvement, should be regarded as the protection scope of the present invention.
