Example one

Referring to fig. 1 and 2, fig. 1 is a schematic three-dimensional structure of an embodiment of the vibration assembly of the present application, and fig. 2 is a simplified diagram of the vibration assembly of fig. 1, showing only one string 30.

The vibration assembly includes a support 20, a string 30, a vibration generator 40, and an abutting member 50.

The string 30 is tensioned against the support 20.

The vibration generator 40 is used to drive the string 30 to vibrate.

The abutting piece 50 is arranged on the bracket 20, abuts against the string 30, and changes the extending direction of the string 30, so that the string 30 forms a first string section 31 and a second string section 32 which are connected with each other and are not collinear, and the position of the abutting piece 50 can be adjusted to change the length ratio of the first string section 31 and the second string section 32. "non-collinear" specifically means: the first and second string segments 31 and 32 are not located on the same line.

The string is held under relatively high tension and the natural frequency of the string is determined by the length, tension, material and string density (mass per unit length). The natural frequencies of first and second chord sections 31 and 32 may be adjusted by changing the lengths of first and second chord sections 31 and 32 without changing other factors of influence.

The following two structures can be adopted for the specific connection manner of the abutting piece 50 and the connecting rod 23.

The abutting member 50 is slidably fitted to the connecting rod 23, detachably and fixedly connected to the connecting rod 23, and supports the string 30 in the radial direction of the connecting rod 23. In fig. 2, the reference axis L1 is the axis of the connecting rod 23. The abutting member 50 can be adjusted in position in the axial direction of the connecting rod 23 to change the length ratio of the first string section 31 and the second string section 32.

Optionally, the vibration assembly comprises a pin (not shown). The connecting rod 23 has a first positioning hole 231, the abutting member 50 has a second positioning hole 521, at least one of the first positioning hole 231 and the second positioning hole 521 is plural, the plural first positioning holes 231 or the plural second positioning holes 521 are arranged at intervals along the axial direction of the connecting rod 23, and the pins are used for being respectively inserted into the corresponding first positioning holes 231 and the corresponding second positioning holes 521.

Specifically, the number of the first positioning holes 231 is plural, and the plural first positioning holes 231 are provided at intervals in the axial direction of the connecting rod 23.

When the position of the abutting piece 50 needs to be adjusted, the pin is pulled out, the abutting piece 50 is moved, and the pin is inserted after the second positioning hole 521 is aligned with the predetermined first positioning hole 231.

The number of the first positioning holes 231 may be one, and the number of the second positioning holes 521 may be plural. A plurality of second positioning holes 521 are provided at intervals along the axis of the connecting rod 23.

The structure II is as follows: the bracket 20 includes a long-strip-shaped connecting rod 23, and the abutting member 50 is sleeved on the connecting rod 23 and is in threaded connection with the connecting rod 23. By rotating the abutting piece 50, the abutting piece 50 can move in the axial direction of the connecting rod 23.

In order to stabilize the position of the abutting member 50 after being adjusted to a predetermined position, the vibration assembly may further include a fastening member (not shown). The fastening member is sleeved on the connecting rod 23, is in threaded connection with the connecting rod 23, and is used for abutting against the abutting piece 50 in the axial direction of the connecting rod 23. The fastener may be a nut.

In this structure, the abutting piece 50 can be located at any position (within the range of the connection thread) in the axial direction of the connecting rod 23.

Referring to fig. 3 to 5, fig. 3 is a schematic three-dimensional structure diagram of the bracket 20 and the abutting element 50 of the vibration assembly shown in fig. 1, fig. 4 is a front view of the abutting element 50 of the vibration assembly shown in fig. 1, and fig. 5 is a cross-sectional view of C-C of fig. 4.

Wherein the string 30 is provided at each end to the first and second mounting elements 21, 22. The abutting piece 50 is disposed on the connecting rod 23, and is adjustable in position in the axial direction of the connecting rod 23. The first mounting part 21, the abutting part 50 and the second mounting part 22 are all arranged in a circular ring/disc shape by taking the connecting rod 23 as a circle center, a plurality of chord lines 30 are arranged at intervals along the circumferential direction of the first mounting part 21, the abutting part 50 and the second mounting part 22, and the radius of the abutting part 50 is between the radius of the first mounting part 21 and the radius of the second mounting part 22.

Optionally, the abutting member 50 is formed with a groove 511 for accommodating the portion of each string 30 abutting against the abutting member 50. The grooves 511 may be replaced by threading holes (not shown). By providing the groove 511 or the threading hole, the position of the string 30 is stabilized and is not easily displaced.

Optionally, the vibration generator 40 is disposed on the first string segment 31 or the second string segment 32, and the vibration generator 40 drives the first string segment 31 and the second string segment 32 to vibrate through self-vibration. In this embodiment, the vibration generator 40 is disposed on the second string portion 32. The vibration generator 40 generates vibration under the blowing of the air flow, thereby driving the string 30 to vibrate.

In other embodiments, the vibration generator 40 may also be an eccentric motor, which is optionally prior art. The eccentric motor includes a motor and a rotating body. The motor is provided on the string 30, the rotating body is attached to the rotating shaft of the motor, and the center of gravity of the rotating body is displaced from the rotating shaft and vibrates by the rotation of the rotating body.

Example two

Referring to fig. 6 to 8, fig. 6 and 7 are a two-dimensional sectional view and a three-dimensional sectional view of an embodiment of the material impurity removing apparatus according to the present application, respectively, in which the cylinder 10 is omitted in fig. 7, and fig. 8 is a sectional view of the material impurity removing apparatus shown in fig. 6, and only one string 30 is retained to more clearly show the string 30.

The material impurity removing device comprises an airflow generator (not shown) and a vibration component.

The airflow generator is used for generating airflow to drive the material 1 to move. Specifically, the air flow generator may be a fan or a high pressure air source that blows air in the direction of the arrows in fig. 6. The airflow generator can also be a negative pressure source which can also drive the air to flow, thereby generating airflow.

The material 1 may be a semi-finished product in the process of moxa production, which is gathered/scooped up, wrapped or stained with impurities (e.g. stems of mugwort leaves). The moxa has the characteristic of being soft, and is suspended in the air and moves (flutters) along with the air flow under the driving of the air flow. The material 1 may also be other materials, such as cotton.

The vibration assembly may be the vibration assembly of the first embodiment. The string 30 (the first segment 31 or the second segment 32) in the vibration assembly intersects with the direction of the air flow for shaking out/ejecting the foreign substances in the material 1 contacting the string 30 by vibration.

Specifically, the vibration assembly includes a support 20, a string 30, a vibration generator 40, and an abutting piece 50.

The string 30 is tensioned against the support 20.

The abutting piece 50 is arranged on the bracket 20, abuts against the string 30, and changes the extending direction of the string 30, so that the string 30 forms a first string section 31 and a second string section 32 which are connected with each other and are not collinear, and the position of the abutting piece 50 can be adjusted to change the length ratio of the first string section 31 and the second string section 32. The first chord section 31 intersects the direction of the airflow so that the material 1 can contact the first chord section 31 during movement with the airflow. The first chord section 31 forms an acute angle a with the direction of the airflow.

The vibration generator 40 is used to drive the string 30 to vibrate. Vibration generator 40 is disposed on second chord section 32.

The first string portion 31 is vibrated by the vibration generator 40. The material 1 moves under the driving of the airflow, and the moving path intersects with the first string section 31, so that the material 1 can contact the first string section 31. After contacting the first string segment 31, the material 1 is attached to the first string segment 31 and moves along the first string segment 31. On the one hand, the relatively high density characteristic of impurity is utilized for first string section 31 is shaking out impurity at the in-process that drives material 1 whipping. On the other hand, the relatively hard nature of the foreign bodies is utilized so that the first string portion 31 ejects the foreign bodies from the material 1 during vibration. Thus, the separation of the material 1 from the impurities is realized.

In order to improve the working efficiency of the material impurity removing device, the number of the strings 30 can be multiple, and the multiple strings 30 are distributed in a radial shape around a reference axis L1, wherein the reference axis L1 is parallel to the airflow direction.

The material impurity removing device can further comprise a cylinder 10, the cylinder 10 is provided with an inlet 11 and an outlet 12, wherein the first chord section 31 is arranged in the cylinder 10, the airflow generator is used for generating airflow in the cylinder 10, and the airflow is used for driving the material 1 to flow into the cylinder 10 from the inlet 11 and flow out of the cylinder 10 from the outlet 12.

In particular, the cylinder 10 extends along a predetermined path, so that the material 1 is conveyed along the predetermined path under the guidance of the cylinder 10. By providing the cylinder 10, a moving path of the material 1 can be defined.

In this embodiment, the impurities are separated from the agglomerated/scooped material 1, and after the separation, the impurities and the plurality of agglomerated/scooped materials 1 are still in a mixed state, and in the subsequent process, the impurities are separated from the plurality of agglomerated/scooped materials 1. Specifically, in an application scenario, the inlet 11 of the cylinder 10 communicates with a pulverizing device (not shown), and the outlet 12 of the cylinder 10 communicates with a cyclone separation device (not shown). The crushing device is used for crushing the raw materials to form the material 1. After the material 1 enters the cylinder 10, the material 1 passes through the first chord section 31, so that impurities are separated from the material 1, the material 1 is separated from the impurities, and the material 1 and the impurities enter the cyclone separation device together with airflow. The cyclone separation device utilizes the centrifugal force generated when rotating at high speed, so that the impurities are separated from a plurality of agglomerated/scooped materials 1 and are left in the cyclone separation device, and the materials 1 enter the subsequent equipment along with the airflow.

Specifically, the above description is only an embodiment of the present application, and not intended to limit the scope of the present application, and all equivalent structures or equivalent processes that are transformed by using the content of the present specification and the attached drawings, or directly or indirectly applied to other related technical fields are also included in the scope of the present application.
