[0038] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0039] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as up and down, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0040] In the description of the present utility model, "plural" means more than two. If there is a description of first and second, it is only for the purpose of distinguishing technical features, and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence of the indicated technical features.

[0041] In the description of the present utility model, unless otherwise clearly defined, terms such as "set", "install", "connect", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0042] Refer to Figures 1 to 4, the conveying and limiting structure for the protein powder packaging bag according to the first aspect embodiment of the present utility model includes a guiding tube 100, a feeding device 200, and a side sweeping machine 300. A guiding plate 110 is installed at the top of the guiding tube 100, and the guiding tube 100 is provided with a strip-shaped hole 120 penetrating through the side wall of the guiding tube 100; the feeding device 200 is used to supply packaging film to the guiding tube 100. The packaging film is supplied to the guiding plate 110 from the back side of the strip-shaped hole 120, and then the packaging film enters the guiding tube 100 through the guiding plate 110. The guiding tube 100 is a cylindrical tube, and the packaging film is a flat plastic film. After the packaging film enters the guiding tube 100 through the guiding plate 110, the packaging film will form a cylinder along the inner side wall of the guiding tube 100. At the same time, the side edge of the packaging film will extend out of the strip-shaped hole 120. After the side edge of the packaging film extending out of the strip-shaped hole 120 and the bottom of the packaging film are heat-sealed, a packaging bag capable of accommodating protein powder will be formed. The side sweeping machine 300 includes a side sweeping brush 330. The side sweeping brush 330 contacts the guiding plate 110, and the side sweeping brush 330 is connected to a telescopic device 320 that drives its movement; if the edge of the packaging film is folded, it may cause the side edge of the packaging film not to extend out of the strip-shaped hole 120 after the packaging film enters the guiding tube 100, and thus cannot be heat-sealed, resulting in the formed packaging bag for filling protein powder not being a sealed packaging bag, and even may cause the protein powder to fall, which will not only reduce the qualified rate of the packaged protein powder, but also cause waste of the protein powder; by setting the side sweeping machine 300 to sweep the edge of the packaging film on the guiding plate 110 flat, the occurrence of the above problems can be effectively reduced. In addition, when the edge of the current packaging film is folded, it is often adjusted and corrected manually. Manual adjustment and correction have problems such as not being able to be discovered in time and inconvenient adjustment. In severe cases, it may be necessary to stop the machine for adjustment, which will greatly affect the filling efficiency. However, through the side sweeping machine 300 for real-time side sweeping, the problem of the edge folding of the packaging film can be greatly avoided, and at the same time, there is no need to stop the machine for adjustment, thereby improving the filling efficiency of the protein powder.

[0043] In the embodiment of the present utility model, the side sweeping machine 300 includes a substrate 310, and the substrate 310 is installed above the guiding tube 100; the fixed end of the telescopic device 320 is installed on the substrate 310, and the side sweeping brush 330 is installed at the movable end of the telescopic device 320. The telescopic device 320 is used to drive the side sweeping brush 330 to lift and lower relative to the guiding plate 110. Specifically, referring to Figure 1 , Figure 2 shown, the telescopic device 320 can be a telescopic cylinder, a telescopic oil cylinder, or an electric telescopic device, etc., which can be specifically selected according to the actual situation; the side sweeping brush 330 is a brush, and the bottom of the side sweeping brush 330 contacts the guiding plate 110. The side sweeping brush 330 is preferably made of materials such as plastic, so that the side sweeping brush 330 has both a certain deformation ability and can sweep the edge of the packaging film flat.

[0044] Further, it is preferably that a plurality of telescopic devices 320 are installed on the substrate 310, so as to Figure 1 , Figure 2 For example, four telescopic devices 320 are installed on the substrate 310, and a edge sweeping brush 330 is installed at the movable end of each telescopic device 320. Two edge sweeping brushes 330 are arranged on each side of the packaging film. The two edge sweeping brushes 330 applicable to the same side of the packaging film alternately lift and lower, so as to ensure that the edge sweeping machine 300 can flatten the edge of the packaging film in real time.

[0045] In the embodiment of the present utility model, the conveying and limiting structure of the protein powder packaging bag further includes a first conveying device 400, a second conveying device 500 and a film pressing device 600. Referring to Figure 1 , Figure 2 As shown, the first conveying device 400 is installed between the feeding device 200 and the guiding tube 100, the second conveying device 500 is installed between the first conveying device 400 and the guiding tube 100, and the second conveying device 500 is used to drive the movement of the packaging film and pre-bend the packaging film; the film pressing device 600 is arranged between the first conveying device 400 and the second conveying device 500, and the film pressing device 600 is used to tension the packaging film. Referring to Figure 1 , Figure 2 As shown, the guiding plate 110 is in the shape of a collar. Along the vertical direction from top to bottom, the width of the guiding plate 110 gradually decreases, and the bottom of the guiding plate 110 corresponds to the strip-shaped hole 120; since the guiding plate 110 is not a horizontal or vertical plane, when the flat packaging film is conveyed to the guiding plate 110, the edge of the packaging film is likely to fold. The second conveying device 500 pre-bends the packaging film, and the pre-bending is to arch a part of the middle position of the packaging film to a certain height, so that the packaging film can better fit the shape of the guiding plate 110, thereby reducing the risk of folding of the edge of the packaging film.

[0046] In the embodiment of the present utility model, the first conveying device 400 includes a first driving shaft 410 and a first driven shaft 420, and the first driving shaft 410 is connected with a first power device that drives it to rotate around its own axis; the packaging film passes through between the first driving shaft 410 and the first driven shaft 420. Specifically, referring to Figure 1 As shown, the packaging film horizontally passes through between the first driving shaft 410 and the first driven shaft 420. The first driving shaft 410 is arranged below the first driven shaft 420. The first power device is preferably a motor. The first driving shaft 410 is arranged below the first driven shaft 420 because the packaging film will fall downward under the action of gravity. Therefore, arranging the first driving shaft 410 below the first driven shaft 420 can ensure that the first driving shaft 410 can always contact the packaging film and drive the packaging film to move.

[0047] In an embodiment of the present utility model, the second conveying device 500 includes a first intermediate structure 510, a second intermediate structure 520, two second driving shafts 530, and two second driven shafts 540. The two second driving shafts 530 are respectively connected to both ends of the first intermediate structure 510, and the two second driven shafts 540 are respectively connected to both ends of the second intermediate structure 520; the second driving shafts 530 and the second driven shafts 540 are both inclined. Specifically, referring to Figure 1 , Figure 3 , the packaging film passes obliquely between the second driving shaft 530 and the second driven shaft 540. The second driving shaft 530 is preferably arranged obliquely below the second driven shaft 540, so as to better ensure that the packaging film always contacts the outer peripheral wall of the second driving shaft 530. The middle position of the first intermediate structure 510 is higher than the outer surface of the second driving shaft 530, so that after the packaging film passes through the second conveying device 500, the packaging film will better conform to the shape of the guide plate 110, thereby reducing the risk of edge folding of the packaging film.

[0048] In an embodiment of the present utility model, the second driving shaft 530 is provided with a retaining edge 541 extending towards the first intermediate structure 510. Specifically, referring to Figure 4 , the retaining edge 541 is arranged on the outer peripheral wall of the second driving shaft 530 and extends towards the first intermediate structure 510, but the end of the retaining edge 541 does not contact the first intermediate structure 510. The purpose of setting the retaining edge 541 is to shield the seam at the connection between the first intermediate structure 510 and the second driving shaft 530, thereby reducing the risk of the packaging film being caught in the seam between the second driving shaft 530 and the first intermediate structure 510.

[0049] In an embodiment of the present utility model, an elastic diaphragm 521 is installed on the side of the second intermediate structure 520 facing the first intermediate structure 510. Specifically, referring to Figure 3 , Figure 4 , there is a gap between the elastic diaphragm 521 and the first intermediate structure 510 for the packaging film to pass through. In addition, the elastic diaphragm 521 can play a role in shielding the seam at the connection between the second intermediate structure 520 and the second driven shaft 540, thereby reducing the risk of the packaging film being caught in the seam between the second intermediate structure 520 and the second driven shaft 540.

[0050] It can be imagined that the elastic diaphragm 521 is made of a material with good deformation ability, such as a plastic film, etc.; but the elastic diaphragm 521 can also be made of hard plastic, and the elasticity will be relatively poor; preferably, the elastic diaphragm 521 is made of a material with good elasticity and is relatively thin; using an elastic material can achieve a better protection effect than using a rigid material and avoid the packaging film from being scratched or damaged.

[0051] In an embodiment of the present utility model, the film pressing device 600 includes a base frame 610 and a film pressing rod 620. The base frame 610 is provided with a mounting hole, and the length direction of the mounting hole is the vertical direction; the film pressing rod 620 is inserted into the mounting hole and can slide along the length direction of the mounting hole; the packaging film abuts against the film pressing rod 620, and the film pressing rod 620 tensions the packaging film by its own gravity. Specifically, referring to Figure 1 As shown, during the conveying process of the packaging film towards the guide plate 110, the film pressing rod 620 will move up and down along the mounting hole. The function of setting the film pressing rod 620 is to tension the packaging film, especially to tension the packaging film from the film pressing rod 620 to the guide plate 110, so as to prevent the problem of lamination of the packaging film from the film pressing rod 620 to the guide plate 110. At the same time, the film pressing rod 620 tensioning the packaging film can also make the packaging film better contact with the second conveying device 500. The film pressing device 600 uses the film pressing rod 620 to tension the packaging film, with a simple structure, good use effect, and low manufacturing cost.

[0052] Referring to Figure 1 、 Figure 2 As shown, the filling equipment according to the second aspect embodiment of the present utility model includes the above-mentioned protein powder packaging bag conveying and limiting structure, and further includes a filling pipe 700, a sealing device 710, and a sealing and cutting device 720; the bottom of the filling pipe 700 is inserted into the guide pipe 100 for filling protein powder into the packaging bag in the guide pipe 100; the base plate 310 of the edge sweeping machine 300 is installed on the filling pipe 700; the sealing device 710 is installed on both sides of the strip-shaped hole 120 for sealing the edges of the packaging film extending out of the strip-shaped hole 120; the sealing and cutting device 720 is installed below the guide pipe 100 for sealing and cutting the packaging bag. The sealing device 710 is used to connect both sides of the packaging film, and the sealing and cutting device 720 is used to perform plastic sealing and cutting on both ends of the protein powder after filling a set weight of protein powder into the packaging bag, so as to form bags of protein powder. Since the filling equipment of this embodiment includes the above-mentioned protein powder packaging bag conveying and limiting structure, it has at least all the beneficial effects of the protein powder packaging bag conveying and limiting structure, and will not be elaborated here.
