[0047] The packaging machine of the present invention also includes a bag-holding structure arranged on the periphery of the discharge nozzle 42. The frame also includes a main body 33 extending vertically, the support frame 2 is fixed on the main body 33, and the bracket is provided with a side portion of the main body 33. The bag holding structure includes a bag holding plate 37 arranged on the main body 33, a clamping plate 39 fixed on the main body 33 and arranged opposite to the bag holding plate 37, and a fourth driving device that drives the bag holding plate 37 close to and away from the clamping plate 39 .
[0048] Specifically, the main body 33 is provided with an inclined plate-shaped mounting frame 35, and the bag-holding plate 37 is arranged on the mounting frame 35 in parallel. The mounting frame 35 and the clamping plate 39 are fixed by a connecting piece 41. Preferably, the included angle between the plane of the bagging plate 37 and the horizontal plane is 30°-45°. The fourth driving device includes a screw hole arranged on the mounting frame 35 and perpendicular to the plane of the mounting frame 35, and a screw threaded in the screw hole and one end connected to the bag-holding plate 37. Therefore, the bag-holding plate 37 can be driven away from and close to the clamping plate 39 by rotating the screw, with simple structure, easy processing, convenient operation and high efficiency. The screw specifically includes a first screw 43 located in the middle of the mounting frame 35 and a number of second screws 44 located in the circumferential direction of the first screw 43, which is beneficial to control the distance between the entire bagging plate 37 and the clamping plate 39 and balance the entire Clamped state. In addition, when the thickness of each part of the bag plane of the contained packaging bag is different, it can also achieve a suitable clamping adjustment. The number of the second screw 44 is preferably six, evenly distributed in the circumferential direction of the first screw 43. At this time, the force balance between the opposing bag plate 37 and the clamping plate 39 is the best. The end of the screw rod facing away from the bag-holding plate 37 and extending out of the mounting frame 35 is vertically provided with a hand wheel, which saves effort and convenience when rotating the screw rod. The diameter of the hand wheel 45 set on the first screw 43 is larger than the diameter of the hand wheel 46 set on the second screw 44. Therefore, the central screw controls the distance between the entire bagging plate 37 and the splint 39, which requires a larger driving force. The diameter of the handwheel required by the screw as a fine adjustment tool can be smaller.
[0049] The side of the clamping plate 39 facing the bag-holding plate 37 is provided with a layer of soft cushion (not shown), which can protect the packaging bag sandwiched between the bag-holding plate 37 and the clamping plate 39. The splint 39 itself is preferably an air-cushioned sandwich panel, and the soft cushion is preferably a foam cushion.
[0050] The bag holding structure further includes a fourth air cylinder 47 connecting the bag holding plate 37 and the main body 33. One end of the fourth air cylinder 47 in the telescopic direction is fixed to the main body 33 and the other end is fixed to the bag holding plate 37. The bag-holding plate 37 is connected to the main body 33 by an air cylinder, which can change the overlapping area with the clamping plate 39 in the plate plane direction and adjust the clamping position of the packaging bag. Specifically, the end of the fourth cylinder 47 connected to the main body 33 is fixed by a screw connection, and the axial direction of the screw connection is perpendicular to the telescopic direction of the fourth cylinder 47. The threaded connection is convenient to adjust the installation angle and adjust the inclination angle of the bagging plate 37 to adapt to different situations.
[0051] The bag-holding structure can be used to place empty packaging bags that are stacked in a sheet shape, such as valve bags. When in use, the screw rods are turned by the hand wheels 45 and 46 to open the distance between the bag placing plate 37 and the clamping plate 39, and a number of stacked packaging bags are placed between the bag placing plate 37 and the clamping plate 39. The size of the board plane of the bagging plate 37 is preferably smaller than the size of the side plane of the packaging bag, so that the clamping plate 39 and the bagging plate 37 are exposed when the packaging bag is placed, so as to facilitate grasping, such as the plane area of ​​the bagging plate 37 It is 2/3 of the surface area of ​​the side of the packaging bag, which is beneficial to maintain the stability of placement and increase the contact area during grasping, thereby increasing the stability of grasping. Then turn the hand wheels 45 and 46 in the opposite direction to clamp the packaging bag, and the clamping force is controlled in a proper range, so that the packaging bag can be extracted smoothly while grabbing the packaging bag without affecting the stability of the other packaging bags.
[0052] When working, the empty packaging bag can be stably placed on the bag-holding structure. The motor 8 drives the first rotating shaft 6 to rotate in the horizontal plane, and drives the manipulator to rotate as a whole until its circumferential angle in the horizontal plane corresponds to the target packaging bag. Then the first air cylinder 12 drives the mechanical arm to rotate around the connecting end 22 until the circumferential angle of the suction cup at its free end in the vertical plane corresponds to the target packaging bag. Finally, the second air cylinder 14 drives the suction cup to approach and contact the target packaging bag and suck it laterally out of the bag placement structure. When the suction cup is sucked, the mechanical claw 32 can be opened to avoid hindering the operation of the suction cup. After that, the suction cup of the manipulator brings the packaging bag back to the discharge nozzle 42. The position of the packaging bag is adjusted by the manipulator to cover the head of the discharge nozzle 42 from the opening for filling, and the mechanical claws 32 clamp both sides of the packaging bag. Enhance stability. The body 9 of the receiving board initially horizontally accepts the upper packaging bag and the materials filled into the packaging bag. After the weighing sensor senses that the material has been filled, after the packaging is completed, the cylinder 3 is driven to drive the rotating piece 25 to rotate, driving the body of the receiving board 9 Turn over and transfer the packaged materials to the conveying equipment. The receiving device is usually arranged above the conveying equipment. When the main body 9 is turned over, the lower end is connected with the conveying end surface of the conveying equipment, which not only provides the power for the packaging bag to slide onto the conveying equipment, but also avoids the height difference causing the packaging bag to fall.
