[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0038] See also Figures 1 to 8 As shown, an embodiment of the present application discloses an open-bag automatic bagging machine, including a bag suction assembly 100, a transfer assembly, a centering assembly, and a bag opening and bagging assembly.
[0039] Specifically, the bag opening and bagging assembly includes an adsorption device 110, a lifting device 120 and a blowing mechanism 130. The adsorption device 110 is used to adsorb the open-mouth bag, the lifting device 120 is used to drive the adsorption device 110 to rise and fall, and the blowing mechanism 130 is arranged on one side of the adsorption device 110; the transfer assembly is used to transfer the open-mouth bag picked up by the adsorption device 110; the centering assembly is used to drive the open-mouth bag to be center; the bag opening and bagging assembly includes a bag opening mechanism and a rocker mechanism, the bag opening mechanism is used to open the open-mouth bag transferred by the transfer assembly, the rocker mechanism is connected to the bag opening mechanism, and the rocker mechanism is used to transfer the opened open-mouth bag.
[0040] In the automatic bagging machine for open-mouth bags provided in the embodiment of the present application, the adsorption device 110 can adsorb the open-mouth bags, and the blowing mechanism 130 can blow off the excess open-mouth bags adhering to the adsorption device 110, thereby avoiding the situation where the adsorption device 110 adsorbs multiple open-mouth bags at the same time, and is also beneficial to improving the stability of the adsorption of the open-mouth bags; the transfer component moves the adsorbed open-mouth bags to the centering station, and then uses the centering component to drive the open-mouth bags to be centered, so as to ensure that the open-mouth bags can be accurately put on the sleeve of the packaging machine; the bag opening and bagging component can open the open-mouth bags and put them on the sleeve of the packaging machine, thereby realizing automatic bagging of the open-mouth bags.
[0041] In some embodiments of the present application, see Figures 1 to 5As shown, the adsorption device 110 includes at least one first suction cup, and the first suction cup is used to adsorb one of the open-mouth bags stored in the bag library 300. Specifically, the first suction cup is connected to the output end of the lifting device 120, and can be lifted and lowered under the drive of the lifting device 120. When sucking the open-mouth bag, the lifting device 120 drives the first suction cup to descend, so that the first suction cup approaches the open-mouth bag, thereby adsorbing the open-mouth bag.
[0042] In this embodiment, please continue to refer to Figures 1 to 5 As shown, there are multiple first suction cups, and the multiple first suction cups are arranged in parallel on the same support frame. Among them, the output end of the lifting device 120 is connected to the support frame, and the lifting device 120 drives the support frame to rise and fall, so as to drive the multiple first suction cups to rise and fall at the same time. In this embodiment, the multiple first suction cups can increase the adsorption force on the open-mouth bag, thereby ensuring the stability of the adsorption of the open-mouth bag.
[0043] In some embodiments of the present application, the transfer assembly includes a plurality of finger cylinders, which are used to clamp the open-mouth bag, wherein the finger cylinders can clamp the open-mouth bag to prevent the open-mouth bag from falling during the transfer process.
[0044] In some embodiments of the present application, the bag opening mechanism includes a telescopic component and two second suction cups arranged opposite to each other. The telescopic component drives the two second suction cups to move toward or away from each other, and each second suction cup is used to absorb and fix the open-mouth bag. In actual work, the second suction cups arranged opposite to each other move toward each other and abut against two sides of the open-mouth bag respectively. The second suction cups absorb the open-mouth bag, and then the two second suction cups move in opposite directions to open the open-mouth bag.
[0045] It is worth to understand that the telescopic assembly can adopt a mechanism that can realize the movement towards and away from each other in the same direction.
[0046] It should be noted that the movement towards each other refers to the movement of the two parts closing together towards the middle of the line connecting the two parts; the movement away from each other refers to the movement of the two parts moving in opposite directions and away from each other.
[0047] In some embodiments of the present application, see Figures 6 to 8 The centering assembly includes at least one pair of centering plates 210 disposed opposite to each other, and the centering plates 210 move toward each other to center the open-mouth bag. Specifically, a pair of centering plates 210 includes two centering plates 210 disposed opposite to each other and in parallel, and the two centering plates 210 can move toward each other or move away from each other. During the centering process, the two centering plates 210 move toward each other, that is, the two centering plates 210 move toward each other until the two centering plates 210 abut against each other.
[0048] It is worth understanding that the position where the two centering clamps 210 abut against each other is the centering position. The open-mouth bag after centering can be in the same straight line with the sleeve of the packaging machine, which can facilitate the open-mouth bag to be sleeved on the sleeve of the packaging machine, which is conducive to improving the accuracy of bagging.
[0049] In some embodiments of the present application, see Figures 6 to 8 As shown, the centering assembly includes a screw mechanism 220 and a driving mechanism 230. The screw mechanism 220 is connected to the centering clamping plate 210. The servo motor drives the screw mechanism 220 to rotate to drive the centering clamping plates 210 on both sides to move closer.
[0050] In some embodiments of the present application, the screw mechanism 220 includes a rotating shaft, and the rotating shaft is provided with a first threaded portion and a second threaded portion with opposite rotation directions at intervals, wherein one centering clamping plate 210 cooperates with the first threaded portion, and the other centering clamping plate 210 cooperates with the second threaded portion. In this embodiment, the first threaded portion and the second threaded portion have opposite rotation directions, and when the rotating shaft rotates, the two centering clamping plates 210 can be driven to move toward or away from each other.
[0051] In some embodiments of the present application, the driving mechanism 230 includes a servo motor, and the rotating shaft is connected to the output end of the servo motor. The servo motor can accurately control the rotation angle of the rotating shaft, which is conducive to improving the control accuracy.
[0052] In some embodiments of the present application, see Figure 1 and Figure 2 As shown, the open-mouth bag automatic bagging machine further includes a bag warehouse 300. The bag warehouse 300 is disposed on one side of the adsorption device 110. The bag warehouse 300 is used to store open-mouth bags.
