In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0037] like Figure 1 and Figure 2 As shown, the powder control device includes a housing 10 , a powder inlet pipe 20 , a powder outlet pipe 30 and a blocking assembly 40 . A cavity 11 is formed inside the shell 10; a powder inlet pipe 20 is arranged on one side of the shell 10, one end of the powder inlet pipe 20 is connected to the powder feeding device, and the other end is connected to the cavity 11 through the powder inlet 12; a powder outlet pipe 30 is arranged on one side of the shell 10, and the powder outlet pipe 30 is connected to the cavity 11 through the powder outlet 13 so that the powder can be discharged; the blocking assembly 40 includes a guide member 41, a connecting member 42 and a blocking member 43, the guide member 41 extends into the cavity 11 from the top of the shell 10, and one end of the guide member 41 extending into the shell 10 is pivotally connected to the connecting member 42, and the other end of the connecting member 42 is pivotally connected to one end of the blocking member 43, and the other end of the blocking member 43 is pivotally connected to the side wall of the cavity 11, and when the guide member 41 reciprocates, it can drive the blocking member 43 to block or open the powder inlet 12 or the powder outlet 13.

[0038] The device includes a shell 10, and a cavity 11 is formed inside the shell 10. The side walls of the cavity 11 are respectively connected to the powder inlet pipe 20 and the powder outlet pipe 30, so that the powder can be mixed with the airflow and enter the cavity 11 through the powder inlet pipe 20, and be discharged from the powder outlet pipe 30 after entering the cavity 11. This process ensures that the powder can be normally transmitted. Secondly, a plugging assembly 40 is arranged at the top of the shell 10, wherein a connecting member 42 pivotally connects the guide member 41 with one end of the plugging member 43, and the other end of the plugging member 43 pivotally connects the side wall of the cavity 11. When the guide member 41 reciprocates, it can drive the plugging member 43 to block or open the powder inlet 12 or the powder outlet 13, thereby realizing the arbitrary control of the on and off of the powder; in addition, since there is no solenoid valve in contact with the powder in this process, even if metal particles are mixed in the powder, the device will not be stuck, thereby ensuring a good use effect.

[0039] It is worth noting that in this embodiment, in order to simplify the overall structure, the guide member 41 is arranged perpendicular to the top of the housing 10, and the device needs to be fixed on a horizontal plane in advance when in use, and the guide member 41 reciprocates up and down in the vertical direction, thereby achieving the blocking and opening of the powder inlet 12 or the powder outlet 13. In other embodiments, the setting position of the device and the setting angle of the guide member 41 can be adjusted according to actual needs, and no other restrictions are made in this embodiment.

[0040] like Figure 1 and Figure 2 As shown, in order to ensure that the powder can smoothly enter from the powder inlet 12 and be discharged from the powder outlet 13 when the device is used normally, the powder inlet pipe 20 and the powder outlet pipe 30 are arranged opposite to each other. This structure can ensure that the powder can be directly discharged from the powder outlet 13 after entering the cavity 11, thereby ensuring the smoothness of the powder transmission process following the airflow.

[0041] It is worth noting that, in this embodiment, Figure 2 As shown, the blocking member 43 is pivotally connected to the side wall of the cavity 11 where the powder inlet 12 is provided. This arrangement can ensure that when the powder transmission needs to be interrupted, the powder inlet 12 is directly blocked by the blocking member 43, and the powder will no longer flow into the cavity 11, thereby causing the problem of excessive pressure in the cavity 11 causing damage to the equipment, thereby ensuring the service life of the equipment.

[0042] To ensure easy installation of the equipment, Figure 2 and Figure 3 As shown, the two ends of the connecting member 42 are detachably connected to the guide member 41 and the blocking member 43, respectively, and the other end of the blocking member 43 is detachably connected to the side wall of the cavity 11 where the powder inlet 12 is provided. The detachable connection not only facilitates the assembly of the blocking assembly 40, but also facilitates subsequent maintenance and replacement of parts, thereby improving the convenience of use. In addition, it is worth noting that in this embodiment, in order to ensure the pivot connection, the detachable connection can also be achieved. Figure 2 and Figure 3 As shown, the two ends of the connecting member 42 are respectively pivoted with the guide member 41 and the plugging member 43 through the pin 47, and the other end of the plugging member 43 is also pivoted to the side wall of the cavity 11 provided with the powder inlet 12 through the pin 47, and one end of the pin 47 is provided with a fixing hole 471. After the pin 47 passes through the guide member 41 and the connecting member 42, the connecting member 42 and the plugging member 43, and the plugging member 43 and the side wall at the same time, the pin 47 can be fixed by passing the fixing hole 471 through the card wire. When the parts need to be replaced, the pin 47 can be disassembled by removing the card wire, and then the disassembly of the connecting member 42 and the plugging member 43 is completed, which is simple and convenient. It is further explained that all other structures that can ensure the pivotal relationship between the guide member 41 and the connecting member 42, the connecting member 42 and the plugging member 43, and the plugging member 43 and the side wall, and can ensure the detachable connection are all within the public protection scope of this embodiment.

[0043] Considering that when the blocking member 43 blocks the powder inlet 12, there may be a gap between the blocking member 43 and the powder inlet 12, Figure 2 and Figure 3 As shown, the powder inlet pipe 20 further includes a first sealing member 14, which is disposed on the outer periphery of the powder inlet 12, and the blocking member 43 can abut against the first sealing member 14 to block the powder inlet 12. Since the first sealing member 14 is disposed on the outer periphery of the powder inlet 12, when the blocking member 43 blocks the powder inlet 12, the gap between the blocking member 43 and the powder inlet 12 is blocked by the first sealing member 14, so that the powder can no longer continue to enter the cavity 11, thereby interrupting the transmission of the powder.

[0044] It is worth noting that, in this embodiment, the first sealing member 14 is an O-ring, which is relatively common and inexpensive, and is a commonly used part to ensure airtightness. In addition, O-rings of different diameters can be selected according to the actual diameter of the powder inlet 12. In other embodiments, the first sealing member 14 can also be a sealing gasket or other structure, as long as a good sealing effect can be ensured, and no other limitation is made in this embodiment. It is further explained that, in this embodiment, the powder inlet 12 is a circular opening, so, if Figure 3 As shown, the plugging member 43 is also cylindrical, so as to ensure that the bottom surface of the cylinder can coincide with the powder inlet 12 during the plugging process, thereby ensuring a good plugging effect. In other embodiments, the specific shapes of the powder inlet 12 and the plugging member 43 can be adjusted according to actual needs, and no other limitations are made in this embodiment.

[0045] Considering that the portion of the guide member 41 located in the cavity 11 will directly contact the powder, long-term use will cause the powder to adhere to the outer surface of the guide member 41. Figure 2 and Figure 3As shown, the blocking assembly 40 further includes a flexible member 44 , which is sleeved on the outer periphery of the guide member 41 located in the cavity 11 . When the guide member 41 reciprocates up and down in the vertical direction, the flexible member 44 can slide along the axial direction of the guide member 41 . It is worth mentioning that the flexible member 44 is movably sleeved on the part of the guide member 41 located in the cavity 11. When the guide member 41 moves from static to dynamic, due to the effect of inertia, the flexible member 44 remains static at the moment of starting, thereby enabling the guide member 41 and the flexible member 44 to generate relative movement. Therefore, in the process of the guide member 41 reciprocating up and down in the vertical direction, the flexible member 44 can slide on the guide member 41 along the axial direction of the guide member 41, so that the powder attached to the outer surface of the guide member 41 is scraped off by the flexible member 44. Moreover, since the flexible member 44 is sleeved on the guide member 41 located in the cavity 11, the two ends can be limited by the top of the shell 10 and the connecting member 42 respectively, so that the flexible member 44 will not fall into the cavity 11 or be taken out of the shell 10, thereby ensuring a good use effect.

[0046] It is worth noting that in this embodiment, the flexible member 44 is a rubber gasket, which is made of a flexible material and will not damage the surface of the guide member 41 during the sliding process. In other embodiments, structures such as silicone gaskets can also be used, as long as they can be made of a flexible material and will not damage the surface of the guide member 41, and this embodiment does not make other restrictions.

[0047] like Figure 1 and Figure 2 As shown, the powder control device further includes a driving assembly 50, which is disposed at the top of the housing 10, and the output end of the driving assembly 50 is transmission-connected to one end of the guide member 41 extending out of the housing 10, so that the guide member 41 can reciprocate up and down in the vertical direction. By providing the driving assembly 50, it is possible to avoid manually driving the guide member 41 to move, improve work efficiency, and save labor costs.

[0048] It is worth noting that, in the present embodiment, the driving assembly 50 includes a driving cylinder 51, a driving piston 52 and an air inlet 53. Among them, the air inlet 53 is connected to the driving cylinder 51, and the output end of the driving piston 52 is transmission-connected to one end of the guide member 41 extending out of the housing 10. The driving cylinder 51 is inflated through the air inlet 53, so that the driving cylinder 51 can drive the piston 52 to reciprocate up and down, thereby enabling the driving piston 52 to drive the guide member 41 connected thereto to reciprocate up and down, that is, the part of the guide member 41 located in the cavity 11 can reciprocate up and down, thereby blocking or opening the powder inlet 12. In other embodiments, any structure that can reciprocate the guide member 41, such as a telescopic motor, is within the protection scope of the present embodiment.

[0049] Considering that the powder will damage the driving cylinder 51 after entering the driving cylinder 51, Figure 2 and Figure 3 As shown, a limiting groove is provided at the top of the housing 10, and a second sealing member 45 is fixedly provided in the limiting groove. The guide member 41 passes through the limiting groove and the second sealing member 45 and extends into the cavity 11. By providing the second sealing member 45, it can be preliminarily ensured that the powder will not enter the driving cylinder 51 from the gap between the guide member 41 and the top of the housing 10, and because the second sealing member 45 is fixed in the limiting groove, even when the guide member 41 reciprocates up and down, the second sealing member 45 will not move, and the sealing effect is good.

[0050] It is worth noting that in this embodiment, the second sealing member 45 is an O-ring, which is relatively common and inexpensive, and is a commonly used part to ensure airtightness, and O-rings of different diameters can be selected according to the actual diameter of the guide member 41. In other embodiments, the second sealing member 45 can also be a sealing gasket or other structure, as long as a good sealing effect can be ensured, and no other limitation is made in this embodiment.

[0051] To further ensure the sealing effect, Figure 2 and Figure 3 As shown, a third seal 46 is provided at the connection between the drive assembly 50 and the housing 10. This arrangement can further ensure that the powder does not enter the drive cylinder 51, thereby ensuring the service life of the equipment. It is worth noting that in this embodiment, the third seal 46 is a pan seal, which can ensure a good sealing effect in both moving and stationary states, and has a high pressure bearing capacity, and is used for sealing the pressure cylinder and the cylinder. In other embodiments, a sealing structure such as a piston ring can also be used, as long as the airtightness of the connection between the housing 10 and the drive assembly 50 can be ensured, and no other restrictions are made in this embodiment.

[0052] In order to facilitate installation, the powder control device also includes a mounting member 60, which includes a first side plate 61 and a second side plate 62. The first side plate 61 and the second side plate 62 are integrally formed and perpendicular to each other, wherein the first side plate 61 is detachably connected to the housing 10, and the second side plate 62 is provided with at least two mounting holes 621, through which the device can be connected to a desired station. In addition, since the first side plate 61 and the second side plate 62 are perpendicular to each other, it is convenient to install the device on a plane, and the first side plate 61 and the second side plate 62 are integrally formed, which can facilitate the processing of the mounting member 60, thereby reducing the manufacturing cost.

[0053] Finally, attach Figure 2 Describe the process of using the powder control device:

[0054] First, the powder feeding device passes the powder into the cavity 11 through the powder inlet 12 of the powder inlet pipe 20, and the powder in the cavity 11 is discharged into the required equipment through the powder outlet 13 of the powder outlet pipe 30;

[0055] Secondly, by moving one end of the guide member 41 pivotally connected to the connecting member 42 toward the inside of the cavity 11 (i.e., vertically moving downward in this embodiment), the blocking member 43 can be driven to block the powder inlet 12 or the powder outlet 13 (in this embodiment, the powder inlet 12 is blocked) to interrupt the transmission of the powder;

[0056] Finally, by moving one end of the guide member 41 pivotally connected to the connecting member 42 toward the top of the shell 10 (i.e., vertically upward movement in this embodiment), the sealing member 43 can be driven to open the powder inlet 12 or the powder outlet 13 (in this embodiment, the powder inlet 12 is opened) to continue conveying powder.

[0057] In summary, the use of the powder control device can not only control the interruption of powder transmission at will without causing the equipment to get stuck, but also ensure the safety, efficiency and smoothness of the operation.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
