DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the present application more obvious, the following will describe the example embodiments according to the present application in detail with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described herein. Based on the embodiments of the present application described in the present application, all other embodiments obtained by those skilled in the art without creative labor shall fall within the scope of protection of the present application.

[0025] In the following description, a large number of details are provided so that the present application can be thoroughly understood. However, those skilled in the art can understand that the following description only exemplarily shows the preferred embodiments of the present application, and the present application can be implemented without one or more such details. In addition, in order to avoid confusion with the present application, some technical features known in the art are not described in detail.

[0026] In order to thoroughly understand the embodiments of the present application, detailed structures will be described in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0027] An embodiment of the present application provides a packaging bag feeding device, which can realize automatic feeding of packaging bags. The following will introduce a packaging bag feeding device according to an embodiment of the present application in detail with reference to the drawings.

[0028] As Figure 1 And Figure 2As shown, the packaging bag feeding device includes a material rack 1 and a rotating material-picking assembly 2 disposed below the material rack 1. The rack has a receiving cavity 11 for stacking packaging bags, and the lower end of the receiving cavity 11 has a discharge port 12. The rotating material-picking assembly 2 has a rotating assembly 21 and an adsorption assembly 22. The rotating assembly 21 is rotatable relative to the material rack 1 between a first angular position and a second angular position. The adsorption assembly 22 is connected to the rotating assembly 21 and rotates with the rotating assembly 21. The adsorption assembly 22 has a first state and a second state. When the rotating assembly 21 rotates to the first angular position, the adsorption assembly 22 is in the first state to adsorb packaging bags through the discharge port 12. When the rotating assembly 21 rotates to the second angular position, the adsorption assembly 22 is in the second state to release the packaging bags.

[0029] like Figure 1 and Figure 2 As shown, the material rack 1 can be tilted to facilitate the user adding packaging bags into the receiving cavity 11 of the material rack 1. Furthermore, there can be two material racks 1 arranged side-by-side. Each material rack 1's outlet 12 can be equipped with a corresponding adsorption component 22. The rotating component 21 can drive the two adsorption components 22 to rotate, simultaneously adsorbing packaging bags from both material racks 1, thus greatly improving the feeding speed of the packaging bag feeding device.

[0030] The first angular position can be specifically represented as the position when the rotating component 21 drives the adsorption component 22 to rotate to the discharge port 12 of the material rack 1. The second angular position can be specifically represented as the position when the rotating component 21 drives the adsorption component 22 to rotate to a position where the packaging bag can be placed.

[0031] The first state and the second state can be respectively represented as different usage states of the adsorption component 22. Specifically, the first state can be represented as the adsorption state of the adsorption component 22. In the first state, the adsorption component 22 can adsorb the packaging bag by generating negative pressure. The second state can be represented as the release state of the adsorption component 22. In the second state, the pressure inside the adsorption component 22 will change, thereby balancing the internal and external pressures of the adsorption component 22, thereby eliminating the adsorption force and releasing the packaging bag.

[0032] The adsorption component 22 can be a suction cup. By using the suction cup to adsorb the packaging bag, it is not only convenient to take out the packaging bag, but also to avoid damage to the packaging bag.

[0033] The packaging bag feeding device can realize automatic feeding of the packaging bags, replace the traditional manual feeding mode, greatly reduce the dependence on the operator and the consumption of the labor cost, and effectively improve the feeding efficiency of the packaging bag feeding device.

[0034] In some embodiments, as shown in Figure 1 The rotating assembly 21 comprises a first driving member 211 and a transmission member 212, two ends of the transmission member 212 are respectively connected with the first driving member 211 and the adsorption assembly 22, and the first driving member 211 drives the adsorption assembly 22 to rotate through the transmission member 212.

[0035] The first driving member 211 can apply a driving force to the adsorption assembly 22 through the transmission member 212 to drive the adsorption assembly 22 to rotate.

[0036] As shown in Figure 1 The transmission member 212 can comprise a driving wheel (not shown in the figure), a driven wheel 2121, a synchronous belt 2122 and a transmission shaft 2123, the first driving member 211 can be connected with the driving wheel, two ends of the transmission shaft 2123 can be respectively connected with the adsorption assembly 22 and the driven wheel 2121, and the synchronous belt 2122 can be sleeved outside the driving wheel and the driven wheel 2121, so that the driving force generated by the first driving member 211 can be transmitted to the adsorption assembly 22 through the driving wheel, the synchronous belt 2122, the driven wheel 2121 and the transmission shaft 2123 in sequence. The diameter of the driving wheel can be smaller than the diameter of the driven wheel 2121, so that the rotating speed of the adsorption assembly 22 can be reduced, and the accuracy and stability of the rotation of the adsorption assembly 22 can be ensured. Of course, the user can adjust the diameters of the driving wheel and the driven wheel 2121 according to the actual use and needs to realize different rotating speeds of the adsorption assembly 22.

[0037] In the above embodiment, the first driving member 211 can accurately control the rotating speed and angle of the adsorption assembly 22, the transmission member 212 can effectively transmit the driving force of the first driving member 211 to the adsorption assembly 22, ensure efficient transmission of the driving force, and through the transmission member 212 connecting the first driving member 211 and the adsorption assembly 22, the compact design and layout of the rotating assembly 21 can be realized.

[0038] In some embodiments, as shown in Figure 1 and Figure 2 A fixing base 3 is arranged between the rack 1 and the rotary taking component 2, the fixing base 3 is provided with a positioning component 31 and a through hole, the through hole is arranged corresponding to the discharge port 12, and the positioning component 31 limits the displacement of the rack 1 when the rack 1 is placed on the fixing base 3.

[0039] The fixing base 3 can not only provide stable support force to the rack 1, but also form a stable connection relationship between the rack 1 and the rotary taking component 2, and the through hole on the fixing base 3 can be matched with the discharge port 12, so that the suction component 22 can sequentially pass through the through hole and the discharge port 12 to suck the packaging bag.

[0040] The positioning component 31 can limit the position of the rack 1 on the fixing base 3, which can not only avoid the situation that the through hole and the discharge port 12 do not correspond in position, resulting in the failure to smoothly suck the packaging bag, but also can avoid the sliding of the rack 1.

[0041] In the above embodiment, through the positioning component 31 and the through hole on the fixing base 3, the accurate correspondence between the through hole and the discharge port 12 can be ensured. The positioning component 31 can limit the displacement of the rack 1 to ensure the stability of the rack 1 during use, avoid the situation that the rack 1 falls due to vibration or accident, effectively reduce the possibility of safety risk occurrence, and improve the practicality and safety of the packaging bag feeding device.

[0042] In some embodiments, as shown in Figure 1 and Figure 2 The positioning component 31 includes a limiting column 311 arranged on the fixing base 3, the limiting column 311 is arranged on the two opposite sides of the rack 1, recesses 13 are respectively formed on the first side wall 15 and the second side wall 16 opposite to each other of the rack 1, and the limiting column 311 at least partially extends into the recess 13 to limit the displacement of the rack 1 in the first direction.

[0043] The first direction can represent the inclination direction of the rack 1, as shown in Figure 1 The number of limiting columns 311 can be multiple, and the multiple limiting columns 311 can be arranged on the two opposite sides of the rack 1 along the inclination direction of the rack 1, so as to limit the displacement of the rack 1 in the first direction.

[0044] The limiting column 311 and the fixing base 3 can be detachably connected or integrally formed, and the detachable connection can include plug-in connection or adhesive connection, which is not limited in the application.

[0045] In the above embodiment, through the cooperation of the limiting column 311 and the groove 13, not only can the through hole on the fixed seat 3 and the discharge port 12 of the material rack 1 correspond accurately, but also the displacement of the material rack 1 in the first direction can be effectively limited, avoiding the situation that the material rack 1 slides off the fixed seat 3, effectively improving the positioning accuracy and overall stability of the material rack 1.

[0046] In some embodiments, as shown in Figure 2 The positioning assembly 31 further includes a second driving member 313 and a limiting plate 312, the second driving member 313 drives the limiting plate 312 to move towards the material rack 1 and abut against the third side wall 17 of the material rack 1, so as to limit the displacement of the material rack 1 in the second direction, wherein the first direction is perpendicular to the second direction, and the first side wall 15 and the second side wall 16 are connected through the third side wall 17.

[0047] The limiting plate 312 can be arranged beside the material rack 1, and can be driven by the second driving member 313 to move in the second direction, i.e. towards or away from the material rack 1. After the material rack 1 is placed on the fixed seat 3 and the groove 13 on the side wall of the material rack 1 is clamped with the limiting column 311 on the fixed seat 3, the limiting plate 312 can be driven to move towards the material rack 1 to abut against the third side wall 17 of the material rack 1, so as to limit the displacement of the material rack 1 in the second direction.

[0048] In some other embodiments, the limiting plate 312 can also be driven to move by mechanical transmission instead of electrical driving.

[0049] In the above embodiment, the limiting plate 312 can abut against the third side wall 17 of the material rack 1, effectively limiting the displacement of the material rack 1 in the second direction, avoiding the situation that the material rack 1 is inclined or displaced due to external force, and further improving the overall stability and safety of the material rack 1.

[0050] In some embodiments, as shown in Figures 1 to 3 The material rack 1 includes a plurality of positioning rods 14, and the plurality of positioning rods 14 enclose the accommodating cavity 11.

[0051] In the above embodiment, the accommodating cavity 11 enclosed by the plurality of positioning rods 14 can enable the user to intuitively observe the number of packaging bags in the accommodating cavity 11, so that when the number of packaging bags in the accommodating cavity 11 is small, the packaging bags can be added in time. In this way, not only can the structure of the material rack 1 be simplified and the manufacturing cost of the material rack 1 be reduced, but also the practicability and convenience of the material rack 1 can be improved.

[0052] In some embodiments, as shown in Figure 3 and Figure 4As shown, the anti-adhesion member 4 is arranged at the discharge port 12 of the material rack 1, and at least part of the anti-adhesion member 4 extends into the discharge port 12. When the suction assembly 22 sucks the packaging bags through the discharge port 12, the adjacent two packaging bags are separated by the anti-adhesion member 4.

[0053] The anti-adhesion member 4 can be in a sheet shape, and the sheet-shaped anti-adhesion member 4 can be located between the packaging bags and the suction assembly 22. The anti-adhesion member 4 can block the packaging bags in the containing cavity 11. When the suction assembly 22 sucks the packaging bags in the containing cavity 11, the packaging bag at the bottom of the containing cavity 11 can be deformed and sucked out of the discharge port 12, and the adjacent packaging bag can be limited in the containing cavity 11 by the anti-adhesion member 4.

[0054] In the above embodiment, the anti-adhesion member 4 can effectively separate the adjacent packaging bags, avoid the blocking or accumulation of the packaging bags due to the adhesion of the packaging bags, and effectively improve the smoothness and practicability of the packaging bag feeding device.

[0055] In some embodiments, as shown in the drawings, Figure 3 The anti-adhesion member 4 is a plurality of anti-adhesion members 4 arranged around the discharge port 12.

[0056] In the above embodiment, the anti-adhesion member 4 arranged around the discharge port 12 can ensure that the adjacent packaging bags can be separated in time and quickly, and further improve the smoothness and practicability of the packaging bag feeding device.

[0057] In some embodiments, as shown in the drawings, Figures 1 to 3 The material rack 1 is provided with a pressing plate 5 away from the rotating material taking assembly 2, and the pressing plate 5 is used to apply an action force to the stacked packaging bags to move them towards the rotating material taking assembly 2.

[0058] The pressing plate 5 can apply an action force to the stacked packaging bags in the containing cavity 11, so that when the packaging bags close to the suction assembly 22 are sucked away, the remaining packaging bags can be pushed to continue moving towards the suction assembly 22.

[0059] The pressing plate 5 can apply an action force to the stacked packaging bags by its own gravity, or by moving the pressing plate 5 by other devices.

[0060] The side of the pressing plate 5 away from the containing cavity 11 can be provided with a pulling part 51, which can make the user more conveniently grasp the pressing plate 5, thereby improving the practicability and convenience of the material rack 1.
