Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] As Figures 1-4As shown, the coffee powder cleaning packaging device according to the embodiment of the application comprises a rack 1, wherein the rack 1 is provided with a feeding cabin 2, the feeding cabin 2 is provided with a stirring piece 3, the rack 1 is further provided with a packaging bag conveying piece 4, the downstream of the packaging bag conveying piece 4 is provided with a packaging bag positioning and packaging piece 5, the packaging bag positioning and packaging piece 5 is matched with the discharge end of the feeding cabin 2. It should be noted that in the specific embodiment of the application, the packaging bag conveying piece 4 is only used as a device for providing packaging bags in batches, and the packaging bag positioning and packaging piece 5 is used for positioning the packaging bag which is displaced to the discharge end of the feeding cabin 2, and for sealing and cutting the packaging bag after the coffee powder is filled. The packaging bag conveying piece 4 and the packaging bag positioning and packaging piece 5 are both mature prior art, and the person skilled in the art is familiar with them, and thus will not be described here.

[0023] It should be noted that, as Figures 2-4 As shown, the discharge end of the feeding cabin 2 is a discharge head 6, the discharge head 6 is provided in three layers, wherein the inner layer and the outer layer are fixedly provided, and the middle layer is reciprocatingly provided between the inner layer and the outer layer. The bottom end of the inner layer and the middle layer is provided with corresponding holes, the holes on the two layers realize closing and opening actions in the process of rotating the middle layer, and the outer layer is provided in a straight cylinder shape.

[0024] Specifically, the feeding cabin 2 is provided in a conical shape so as to facilitate the coffee powder inside to converge to the discharge end. The feeding cabin 2 is fixedly connected with a feeding motor 21, the output shaft of the feeding motor 21 is connected with a first transmission shaft 22 through a key, the first transmission shaft 22 extends into the feeding cabin 2 and is coaxially fixedly connected with a feeding auger 23, and the feeding auger 23 extends to the discharge end of the feeding cabin 2. It can be understood that during filling, the feeding motor 21 drives the first transmission shaft 22 to rotate, and then drives the feeding auger 23 to rotate, so that the feeding auger 23 continuously conveys the coffee powder in the feeding cabin 2 to the discharge end of the feeding cabin 2, and discharges the coffee powder from the discharge end to the corresponding packaging bag, thereby forming filling.

[0025] As Figure 2As shown, the stirring member 3 comprises a stirring motor 31, a second transmission shaft 32, a chain wheel set 33, a transmission seat 34 and stirring blades 35, the stirring motor 31 is fixedly connected to the feeding cabin 2; the second transmission shaft 32 is rotatably connected to the feeding cabin 2 and is keyed to the output shaft of the stirring motor 31; one end of the chain wheel set 33 is keyed to the second transmission shaft 32, and the other end of the chain wheel set 33 is fixedly sleeved on the first transmission shaft 22 through a bearing; the transmission seat 34 is rotatably sleeved on the first transmission shaft 22, and the end of the transmission seat 34 is fixedly connected to the chain wheel at one end of the chain wheel set 33; the stirring blades 35 are fixedly connected to the circumferential side of the transmission seat 34, so it can be known that the transmission seat 34 rotates following the rotation of the chain wheel on the chain wheel set 33, therefore, the rotation of the chain wheel set 33 will be driven by the rotation of the second transmission shaft 32 driven by the stirring motor 31, and the rotation of the chain wheel set 33 will not interfere with the first transmission shaft 22, at the same time, the transmission seat 34 can be driven to rotate through the chain wheel on the chain wheel set 33 which is sleeved on the first transmission shaft 22, so the stirring blades 35 will rotate in the feeding cabin 2, and the coffee powder in the feeding cabin 2 can be stirred to improve the effect of gathering the coffee powder in the feeding cabin 2 to the discharge end.

[0026] As shown in Figure 3 and Figure 4 As shown, the discharge head 6 comprises a positioning sleeve 61, a discharge nozzle 62, a rotating drum 63, a positioning cylinder 64 and a micro motor 65, the positioning sleeve 61 is fixedly connected to the discharge end of the feeding cabin 2; the discharge nozzle 62 is the inner layer of the discharge head 6, and is fixedly connected to the positioning sleeve 61 coaxially; the rotating drum 63 is the middle layer of the discharge head 6, and is rotatably connected to the positioning sleeve 61, and is sleeved on the discharge nozzle 62; the positioning cylinder 64 is the outer layer of the discharge head 6, and is sleeved on the rotating drum 63 and is fixedly connected to the positioning sleeve 61; the micro motor 65 is fixedly connected to the positioning sleeve 61, and provides the rotating power for the rotating drum 63.

[0027] Among them, the bottom end of the discharge nozzle 62 is uniformly provided with a plurality of discharge holes 621 in the circumferential direction, and the bottom end of the rotating drum 63 is uniformly provided with a plurality of sealing holes 631 in the circumferential direction, the sealing holes 631 and the discharge holes 621 correspond one by one and are the same size, and the cross-sectional area of the sealing hole 631 is smaller than the area between the adjacent two sealing holes 631.

[0028] As can be known, when the rotating drum 63 rotates, the sealing holes 631 thereon will form a coincident state with the discharge holes 621 on the discharge nozzle 62, at this time, the coffee powder can be smoothly delivered from the discharge head 6, and when the sealing holes 631 and the discharge holes 621 form a misaligned state, at this time the bottom end of the rotating drum 63 will form a plugging state to the discharge holes 621, at this time the coffee powder will not be delivered from the discharge head 6.

[0029] It should be noted that the feeding auger 23 extends into the discharge nozzle 62, and the side wall of the feeding auger 23 and the inner wall of the discharge nozzle 62 are gap-matched to form a conveying effect for the coffee powder.

[0030] like Figure 3 and Figure 4 As shown, an arc-shaped rack 632 is circumferentially provided on the side wall of the rotating cylinder 63; an arc-shaped notch 641 is provided on the side wall of the positioning cylinder 64; the arc-shaped rack 632 is located in the arc-shaped notch 641, and the arc length of the arc-shaped notch 641 is greater than the arc length of the arc-shaped rack 632.

[0031] This allows the arc-shaped rack 632 to rotate within the arc-shaped notch 641 over a certain distance when the rotating drum 63 rotates.

[0032] Furthermore, a gear 651 is keyed to the output shaft of the micro motor 65 , and the gear 651 is meshed with the arc-shaped rack 632 .

[0033] It should be noted that the micro motor 65 has braking and forward and reverse rotation functions.

[0034] It should be further explained that the inner side of the end of the drum 63 and the outer side of the end of the discharge nozzle 62 are in contact with each other.

[0035] It can be seen that during the filling interval (during the packaging bag conveying process) (during this process, the feeding click 21 and the stirring motor 31 are stopped), the micro motor 65 drives the gear 651 to rotate, driving the arc rack 632 and the rotating drum 63 to rotate at a certain angle, so that the sealing hole 631 and the discharge hole 621 are misaligned. At this time, the rotating drum 63 will form a blocking state for the discharge nozzle 62. In this state, the coffee powder in the discharge nozzle 62 will not leak. When the next packaging bag is placed on the positioning cylinder 64, the micro motor 65 The driving gear 651 rotates in the opposite direction, so that the sealing hole 631 and the discharge hole 621 overlap. At this time, the feeding motor 21 and the stirring motor 31 are started, and the coffee powder in the feeding chamber 2 will be discharged into the packaging bag from the overlapping discharge hole 621 and the sealing hole 631, forming a filling effect. After the filling is completed, the packaging bag is sealed and cut by the packaging bag positioning packaging part 5 to complete the filling of the coffee powder. It should be noted that the design of the positioning cylinder 64 ensures that the packaging bag will not be affected by the rotation of the rotating cylinder 63 after it is placed on the discharge head 6.

[0036] It should be noted that the specific models and specifications of the feeding motor 21, feeding auger 23, stirring motor 31, sprocket group 33, transmission seat 34, stirring blade 35, packaging bag conveyor 4, packaging bag positioning packaging part 5, micro motor 65, arc rack 632 and gear 651 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The above merely provides preferred embodiments of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall fall into the protective scope of the present application.
