[0023] See also Figure 1 As shown, according to an embodiment of the present application, a material loosening device is provided, including a frame 1, a material tapper 2, a driving part 3 and a guide part 4, the material tapper 2 is movably arranged on the frame 1, the material tapper 2 is connected to the driving part 3, so that the driving part 3 drives the material tapper 2 to rotate, and at least one section of the rotation path of the material tapper 2 is rotated along the first direction toward the material to cut the material; the material tapper 2 is slidably arranged in the guide part 4, and the guide part 4 is used to drive the material tapper 2 to swing at least along the second direction during the rotation of the material tapper 2 with the driving part 3 to remove the cut material.

[0024] The material loosening device provided in the embodiment of the present application can drive the material loosening device 2 movably arranged on the frame 1 to rotate toward the material by setting a driving part 3, so that the material loosening device 2 can cut into the material and prevent the subsequent material from falling, thereby achieving the purpose of cutting the material, thereby improving the degree of loosening of the material and ensuring the stability of the material flow entering the next process; at the same time, by setting a guide part 4 and making the material loosening device 2 slidably arranged in the guide part 4, the material loosening device 2 can be pulled during the rotation of the material loosening device 2, so that the material loosening device 2 can swing to take away the cut material, thereby achieving the purpose of quickly peeling off and throwing away the cut material.

[0025] The material may be tobacco flakes, slag or grains, etc. In the embodiment of the present application, the material is tobacco flakes, and the material loosening device is used to separate the tobacco flakes into slices during the transportation process of the tobacco flakes to ensure that the looseness of the tobacco flakes is uniform.

[0026] Specifically, the tobacco sheets can be transported by material handling machinery such as a belt conveyor. As an implementation method, the material loosening device is arranged at the head of the belt conveyor, that is, the material loosening device is arranged at the discharge part of the belt conveyor; as another implementation method, the material loosening device is arranged at the body of the belt conveyor, that is, the material loosening device is arranged at the conveying section of the belt conveyor. In the embodiment of the present application, the material loosening device is arranged at the discharge part of the belt conveyor, and the material loosening device is located above the material.

[0027] The material loosening device includes a frame 1 and a material tapper 2, the frame 1 is relatively fixed to the body of the belt conveyor, and the material tapper 2 is arranged on the frame 1. In the present application, the frame 1 is provided to provide a stable setting position for the material tapper 2, thereby improving the working stability of the material tapper 2.

[0028] Specifically, the material tapper 2 is movably connected to the frame 1, and the working state of the material tapper 2 includes a first state and a second state. When the material tapper 2 is in the first state, the material tapper 2 is used to cut the material; when the material tapper 2 is in the second state, the material tapper 2 is used to throw the cut material. It should be noted that during cutting, the material tapper 2 can slowly cut into the material and prevent the subsequent material from falling. After cutting to a certain depth, the material tapper 2 can swing quickly to peel off and throw the cut material.

[0029] The material loosening device further comprises a driving part 3 and a guiding part 4 . The driving part 3 may be a motor, and the driving part 3 is relatively fixed to the frame 1 . The guiding part 4 may be a guiding groove, and the guiding groove is provided on the frame 1 .

[0030] Specifically, the material tapper 2 is connected to the driving part 3, and the driving part 3 is used to drive the material tapper 2 to rotate. At least one section of the rotation path of the material tapper 2 moves toward the material along the first direction, so that the material tapper 2 can get close to the material until it abuts against the upper surface of the material and applies pressure to the material. The material is broken under the action of the pressure applied by the material tapper 2, so as to achieve the purpose of loosening the material. It should be noted that the material tapper 2 is also slidably arranged in the guide part 4. In the process of the driving part 3 driving the material tapper 2 to rotate, the guide part 4 is used on the one hand to limit the rotation path of the material tapper 2 in the process of the material tapper 2 rotating toward the material, so that at least one section of the rotation path of the material tapper 2 rotates toward the material along the first direction; on the other hand, it is used to pull the material tapper 2 to swing at least in the second direction after the material tapper 2 cuts the material, so as to achieve the purpose of peeling and throwing off the cut material.

[0031] When the material tapper 2 is in the first state, the material tapper 2 moves toward the material in a first direction to cut the material. The first direction may be an arc direction, and the first direction may be the direction in which the material tapper 2 moves along an arc track.

[0032] When the material tapper 2 is in the second state, the material tapper 2 swings at least in the second direction to carry away the cut materials. The second direction can be a tangent direction of the swing direction of the material tapper 2, and the second direction can be a transfer direction of the materials.

[0033] It can be understood that the movement path of the material tapper 2 is an irregular arc, and the movement path of the material tapper 2 is similar to the action path of "planing".

[0034] In some possible implementations provided in this application, see Figure 1 As shown, the material loosening device also includes a transmission part 5 and a first connecting part 6. The first connecting part 6 is arranged on the material tapper 2. The transmission part 5 is arranged between the frame 1 and the material tapper 2 and is rotatably connected to the first connecting part 6. The driving part 3 is arranged on the side of the frame 1 away from the material tapper 2. The driving end of the driving part 3 passes through the frame 1 and is connected to the transmission part 5. The driving part 3 is used to drive the transmission part 5 to rotate so as to drive the material tapper 2 to move through the first connecting part 6.

[0035] Among them, the first connecting part 6 can be a cylindrical long rod, the first connecting part 6 is relatively fixed to the material tapper 2, the first connecting part 6 is arranged in the middle of the material tapper 2, and the first connecting part 6 extends in a direction perpendicular to the frame 1 and is rotatably connected to the transmission part 5.

[0036] Specifically, the transmission part 5 is arranged between the material selector 2 and the frame 1, and the transmission part 5 is parallel to the frame 1. An axial hole is opened on the transmission part 5 at a position away from the center point. A first bearing is rotatably arranged in the axial hole, and the first bearing is connected to the first connecting part 6.

[0037] Among them, the driving part 3 is arranged on the side of the frame 1 away from the transmission part 5. A through hole is opened on the frame 1, and the through hole penetrates the frame 1 in a direction perpendicular to the frame 1. The driving end of the driving part 3 can penetrate the frame 1 through the through hole and be connected to the transmission part 5.

[0038] Specifically, the connection position between the transmission part 5 and the driving end of the driving part 3 is at the center point of the transmission part 5. The driving part 3 is used to drive the transmission part 5 to rotate with the center point of the transmission part 5 as the rotation center. When the transmission part 5 rotates, it can drive the material tapper 2 to rotate with the center point of the transmission part 5 as the rotation center through the first connecting part 6. In the present application, by setting the first connecting part 6 to be rotatably connected with the transmission part 5, the material tapper 2 and the transmission part 5 can be rotatably connected, so that the transmission part 5 drives the material tapper 2 to rotate with the center point of the transmission part 5 as the rotation center, and the material tapper 2 can also rotate with the connection point of the first connecting part 6 and the transmission part 5 as the rotation center, so that the material tapper 2 can move toward the material when it rotates.

[0039] In the above embodiments, see Figure 1 As shown, the transmission part 5 is a transmission disc, the middle part of the transmission disc is connected to the driving part 3 , and the outer edge of the transmission disc is connected to the first connecting part 6 .

[0040] The middle of the transmission disc may be where the center of the transmission disc is located.

[0041] The outer edge of the transmission disc may be a position on the transmission disc far away from the center of the circle.

[0042] Specifically, the driving end of the driving part 3 is coaxially arranged with the transmission disc, and the driving part 3 is used to drive the transmission disc to rotate with the center of the circle of the transmission disc as the rotation center.

[0043] In addition, the transmission part 5 can also be arranged as follows:

[0044] The transmission part 5 is a transmission rod, the middle part of the transmission rod is connected to the driving part 3 , and the end part of the transmission rod is connected to the first connection part 6 .

[0045] The middle part of the transmission rod may be the location of the symmetry center of the transmission rod.

[0046] The end of the transmission rod may be an end of the transmission rod away from the symmetry center.

[0047] Specifically, the driving end of the driving part 3 coincides with the symmetry center of the transmission rod, and the driving part 3 is used to drive the transmission rod to rotate with the symmetry center of the transmission rod as the rotation center.

[0048] In the above embodiments, see Figure 1 As shown, a second connecting portion 7 is disposed at one end of the material tapper 2 away from the material. The second connecting portion 7 is rotatably disposed in the guide portion 4 and is suitable for reciprocating along the extension direction of the guide portion 4 .

[0049] Among them, the second connecting part 7 can also be a cylindrical long rod, the second connecting part 7 is relatively fixed to the material tapper 2, the second connecting part 7 is arranged at one end of the material tapper 2 away from the material, the second connecting part 7 extends in a direction perpendicular to the frame 1 and is rotatably arranged in the guide part 4, and is suitable for reciprocating movement along the extension direction of the guide part 4.

[0050] Specifically, the guide portion 4 is provided on the frame 1, one end of the guide portion 4 extends toward the direction close to the rotation center of the transmission portion 5, and the other end extends toward the direction away from the rotation center of the transmission portion 5. A second bearing is rotatably provided in the guide portion 4, and the second connecting portion 7 is connected to the second bearing, and the second bearing is suitable for driving the second connecting portion 7 to reciprocate along the extension direction of the guide portion 4.

[0051] In the present application, by setting the second connecting portion 7 to be rotatably arranged in the guide portion 4 and suitable for reciprocating movement along the extension direction of the guide portion 4, the material tapper 2 can be rotatably arranged in the guide portion 4 and suitable for reciprocating movement along the extension direction of the guide portion 4, so that the material tapper 2 can reciprocate in the guide portion 4 while also being able to rotate with the connection point between the second connecting portion 7 and the second bearing as the rotation center.

[0052] In the above embodiments, see Figure 1 As shown, the guide portion 4 is arc-shaped, one end of the guide portion 4 extends toward the rotation center of the transmission portion 5, and the other end extends toward the rotation center of the transmission portion 5 and the material entry side, and the arc-shaped opening of the guide portion 4 faces the material discharge side.

[0053] By setting the guide portion 4 to be arc-shaped, it is possible to avoid the material tapper 2 from getting stuck, so that the material loosening device can operate smoothly.

[0054] The material discharge side may be the side of the cut material opposite to the guide portion 4 .

[0055] In the above embodiments, see Figure 1 As shown, the end of the guide portion 4 away from the transmission portion 5 is the first extreme position, the end of the guide portion 4 close to the transmission portion 5 is the second extreme position, the movement trajectory of the first connection portion 6 is a circular path, and when the second connection portion 7 moves from the first extreme position to the second extreme position, the first connection portion 6 moves counterclockwise from the highest point of the circular path to the lowest point of the circular path, and when the second connection portion 7 moves from the second extreme position to the first extreme position, the first connection portion 6 moves counterclockwise from the lowest point of the circular path toward the highest point of the circular path.

[0056] The movement of the second connecting portion 7 in the guide portion 4 is equivalent to the movement of the material tapping device 2 in the guide portion 4 .

[0057] Specifically, when the material tapper 2 is working in the first state, the driving part 3 drives the transmission part 5 to rotate in the counterclockwise direction with the center point of the transmission part 5 as the rotation center, and the transmission part 5 rotates in the counterclockwise direction, drives the material tapper 2 to approach the material through the first connecting part 6, and realizes the cutting of the material through the rotation of the material tapper 2. At this time, the material tapper 2 moves from the first extreme position to the second extreme position in the guide part 4; when the material tapper 2 is moving in the second state, the driving part 3 continues to drive the transmission part 5 to rotate in the counterclockwise direction with the center point of the transmission part 5 as the rotation center, and the transmission part 5 rotates in the counterclockwise direction, drives the material tapper 2 to move away from the material through the first connecting part 6, and realizes the throwing of the cut material through the rotation of the material tapper 2. At this time, the material tapper 2 moves from the second extreme position to the first extreme position in the guide part 4.

[0058] The height of the position where the first extreme position is located is higher than the height of the position where the second extreme position is located. It should be noted that when the material tapper 2 is in the first state, the first connecting portion 6 moves from the highest point of the circular path in a counterclockwise direction to the lowest point of the circular path, and the material tapper 2 has a tendency to move downward and rotate counterclockwise; when the material tapper 2 is in the second state, it moves from the lowest point of the circular path in a counterclockwise direction toward the highest point of the circular path, and the material tapper 2 has a tendency to move upward and rotate counterclockwise.

[0059] In some possible implementations provided in this application, see Figure 1 As shown, the material tapper 2 has a cutting portion 21 at one end close to the material, and the cutting portion 21 is used to cut into the material.

[0060] Providing a cutting portion 21 at one end of the material dispenser 2 close to the material is helpful for cutting the material, optimizing the loosening effect of the material, and ensuring that the loosening degree of the material is uniform.

[0061] The cutting part 21 is arranged at one end of the material tapping device 2 close to the material. As an embodiment, the cutting part 21 and the material tapping device 2 are integrally formed. As another embodiment, the cutting part 21 and the material tapping device 2 are split, and the cutting part 21 is fixedly connected to the material tapping device 2. In the embodiment of the present application, the cutting part 21 and the material tapping device 2 are integrally formed, which can avoid the split cutting part 21 and the material tapping device 2 from breaking at the connection, thereby improving the working stability of the material loosening device.

[0062] Specifically, the cutting portion 21 is set at an angle with the material selector 2, and the angle between the cutting portion 21 and the material selector 2 is an obtuse angle. The opening direction of the angle between the cutting portion 21 and the material selector 2 is toward the material discharge side, so that when cutting the material, the cutting portion 21 is perpendicular to the upper surface of the material, which is conducive to cutting the material. It should be noted that the end of the cutting portion 21 away from the material selector 2 is a tip, and the tip is set toward the material.

[0063] In the above embodiments, see Figure 1 As shown, the cutting portion 21 is a cutting plate, and the cutting plate is in a long strip shape.

[0064] By setting the cutting portion 21 as a long strip-shaped cutting plate, the contact area between the material dispenser 2 and the material is increased, which is conducive to cutting the material as a whole.

[0065] In addition, the cutting portion 21 may also be arranged in the following manner:

[0066] The slitting portion 21 is a slitting fork, which includes a plurality of slitting teeth arranged at intervals along the length direction of the slitting fork.

[0067] The cutting portion 21 is provided as a cutting fork, which facilitates piercing into the material, and can cut the whole piece of material into a plurality of small pieces, thereby optimizing the loosening effect of the material and ensuring that the loosening degree of the material is uniform.

[0068] The material loosening device provided in the embodiment of the present application can drive the material loosening device 2 movably arranged on the frame 1 to rotate toward the material by setting a driving part 3, so that the material loosening device 2 can cut into the material and prevent the subsequent material from falling, thereby achieving the purpose of cutting the material, thereby improving the degree of loosening of the material and ensuring the stability of the material flow entering the next process; at the same time, by setting a guide part 4 and making the material loosening device 2 slidably arranged in the guide part 4, the material loosening device 2 can be pulled during the rotation of the material loosening device 2, so that the material loosening device 2 can swing to take away the cut material, thereby achieving the purpose of quickly peeling off and throwing away the cut material.

[0069] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0070] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
