Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a device for opening and filling an open bag. Background Art

[0002] Open-mouth bags are commonly used packaging materials. When using open-mouth bags for packaging, the bags must first be taken out of the material warehouse, then opened, and then a dedicated bag opening device is used to transfer the bags in the open state to a dedicated bag clamping device to enter the next packaging process. The bag opening device used in this process is usually a suction cup device. The transfer device needs to connect the material warehouse position and the bag clamping device position, which are generally relatively far apart. In addition, the bag clamping device is set at a high position. During the transfer process, the bag may sometimes fall off due to distance and equipment structure reasons. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a device for opening and loading open-mouth bags, which can improve the stability of bag transfer and the compactness of production line steps, thereby improving production efficiency.

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide an open-mouth bag opening and bagging device, the open-mouth bag opening and transferring mechanism includes: a frame, a flipping bagging mechanism and a bag-holding mechanism, the flipping bagging mechanism is installed on the frame, there are two bag-holding mechanisms, which are symmetrically installed on the flipping bagging mechanism; the frame as a whole is in an inverted T shape, including a crossbeam and a longitudinal beam, the longitudinal beam is vertically fixed on the crossbeam, the flipping bag-holding mechanism includes a rotary drive mechanism, a rotating shaft and a swing table, the rotating shaft is hoisted below the crossbeam, the swing table is installed based on the rotating shaft, and the A rotating drive mechanism is installed on the frame, and the drive mechanism can push the swing table to rotate 90° outward around the rotating axis. The bag-supporting mechanism includes a base, a strut and a strut drive mechanism. There are two bases, which are symmetrically fixed on both sides of the swing table based on the bottom of the swing table. A strut drive mechanism is installed on the inner side of each base, and a strut is installed on each strut drive mechanism. The rod head of the strut is provided with an F-shaped structure, and the rod tail of the strut is installed in the strut drive mechanism. The strut drive mechanism can drive the two struts to perform rotation and relative closing and separation actions at the same time.

[0005] In a preferred embodiment of the present invention, the rotary drive mechanism comprises a first telescopic cylinder, a transmission plate, and a right-angle adapter plate. The transmission plate is mounted at the top of the swing table and perpendicular to the swing table. The right-angle adapter plate is located on the side of the transmission plate facing away from the swing table. The first telescopic cylinder is vertically fixed behind the longitudinal beam. The end of the telescopic rod of the first telescopic cylinder is hingedly connected to the right-angle adapter plate. When the telescopic rod of the first telescopic cylinder is extended, it drives the right-angle adapter plate to push the transmission plate to a vertical position. At this time, the swing table swings upward to a horizontal bag-holding position under the action of the transmission plate. When the telescopic rod of the first telescopic cylinder is retracted, the right-angle adapter plate drives the transmission plate to rotate upward to a horizontal position. At this time, the swing table returns to a downward bag-supporting position under the combined action of gravity and the transmission plate. A positioning mounting bracket is mounted behind the longitudinal beam. The cylinder body of the first telescopic cylinder is fixed parallel to the longitudinal beam by the positioning mounting bracket. A hoisting positioning plate is provided between the first telescopic cylinder and the top of the crossbeam.

[0007] In a preferred embodiment of the present invention, a plurality of hydraulic buffers are installed between the swing table and the crossbeam.

[0008] The beneficial effects of the present invention are as follows: the present invention changes the structure of the traditional bag opening and transferring device into a structure in which the support rod is opened and then turned 90 degrees to cooperate with the bag clamping mechanism to load the material. In this loading method, the highest point of the support rod movement is low from the bag opening, so that the coordinated installation position of the bag clamping device of the packaging machine is relatively low, and the space for the production line layout is more compact. In addition, an F-shaped structure is provided at the top of the support rod, which can effectively increase the force between the support rod and the bag opening through the rotating action, thereby significantly improving the stability of feeding.

[0021] The rotary drive mechanism is mounted on the frame and includes a first telescopic cylinder 9, a transmission plate 6, and a right-angle adapter plate 7. The transmission plate 6 is mounted on top of the swing table 5 and is perpendicular to the swing table 5.

The cylinder body of the first telescopic cylinder 9 is fixed parallel to the longitudinal beam 2 by the positioning mounting bracket 3. A hoisting positioning plate 4 is provided between the first telescopic cylinder 9 and the top of the crossbeam 2. The end of the telescopic rod of the first telescopic cylinder 9 is connected to the right-angle adapter plate 7 by a hinge. When the telescopic rod of the first telescopic cylinder 9 is extended, it can drive the right-angle adapter plate 7 to push the transmission plate 6 to a vertical position. At this time, the swing table 5 swings upward to the horizontal bag clamping position under the action of the transmission plate 6. When the telescopic rod of the first telescopic cylinder 9 is retracted, the right-angle adapter plate 7 can drive the transmission plate 6 to rotate upward to a horizontal position. At this time, the swing table 5 returns to the bag-holding position directly below under the combined action of gravity and the transmission plate 6.

[0022] The bag-supporting mechanism includes a base 17, a support rod 8 and a support rod driving mechanism. There are two bases 17, which are symmetrically fixed on both sides of the swing table 5 based on the bottom of the swing table 5. A support rod driving mechanism is installed on the inner side of each base 17, and a support rod 8 is installed on each support rod driving mechanism. The rod head of the support rod 8 is provided with an F-shaped structure, and the rod tail of the support rod 8 is installed in the support rod driving mechanism. The support rod driving mechanism can drive the two support rods to rotate and perform relative closing and separation actions at the same time.

The strut driving mechanism includes a second telescopic cylinder 10, a third telescopic cylinder 11, a strut hanger 13 and a cylinder seat 14. The tail diameter of the strut 8 is larger than the rod diameter of the strut 8. The tail of the strut 8 can be rotatably installed on the inside of the strut hanger 13. The outer side of the top of the strut hanger 13 is connected to the bottom plate of the base 17 by a hinge 12. The cylinder seat 14 is provided at On the inside of the strut hanger 13, the second telescopic cylinder 10 is installed on the cylinder seat 14 and is located on the inside of the strut 8.

The cylinder body of the third telescopic cylinder 11 is rotatably installed on the side panel, and the end of the telescopic rod of the third telescopic cylinder 11 is hinged to the swing connecting frame 13.

[0024] The working principle of this embodiment is as follows:

[0025] When performing bag-opening operation,

[0026] In the first step, the bag in the lower bag storage opens under the action of the bag opening mechanism, and at the same time, the telescopic rod of the first telescopic cylinder 9 retracts, pulling the right-angle adapter plate 7 to move the swing table 5 downward. At this time, the telescopic rods of the two third telescopic cylinders 11 are in an extended state, and the two support rods 8 are closed towards each other, so that when the swing table 5 reaches the vertical downward position, it can just enter the opened bag mouth.

[0027] In the second step, the telescopic rod of the third telescopic cylinder 11 retracts, so that the support rod 8 holds the bag opening tightly. Then the telescopic rod of the second telescopic cylinder 10 extends to drive the rotating arm 16 to rotate, so that the support rod 8 rotates as a whole. In this way, the F-shaped structure at the top of the support rod 8 can tightly clamp the bag opening, so that the packaging bag can remain taut.

[0028] In the third step, the telescopic rod of the first telescopic cylinder 9 extends downward to push the right-angle adapter plate 7, so that the swing table 5 moves upward to a horizontal position, and the material bag is put on the bag clamping mechanism of the packaging machine, and the bag clamping mechanism of the packaging machine clamps the bag.

[0029] In the fourth step, the telescopic rod of the second telescopic cylinder 10 is retracted, driving the support rod 8 to rotate as a whole, so that the F-shaped structure at the top is separated from the bag opening, and then the telescopic rod of the third telescopic cylinder 11 is extended, so that the two support rods 8 are relatively closed and separated from the bag opening;

[0030] Repeat the above steps 1 to 4 to continuously transfer the material bags in the material library to the bag clamping mechanism.

[0031] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
