Description

Technical Field

[0002] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0003] Paper bag machines process paper bags in various sizes. If a paper bag machine can only accommodate one size, its application range will be greatly limited. Traditional paper bag machines also have some adjustment mechanisms, but the adjustment structure is complex and inconvenient. In traditional technology, the upper part uses 6 sets of lead screws for adjustment, and the lower part uses 6 sets of lead screws for adjustment. Each set of lead screws controls the movement of one mechanism. To adjust the opening and closing of the second, third, fourth, and fifth sets, the position of each set needs to be adjusted separately. This requires four adjustments. The traditional method has a cumbersome structure, requires a large space, and requires 6 sets of adjustment lead screws for both the upper and lower parts, making the adjustment method complex and requiring many adjustments.

[0004] CN213891513U discloses a paper bag machine adjustment mechanism, including a connecting rod one, a connecting rod two, and a fixing plate. A handle one is fixedly installed on the outer side of the connecting rod one, and an adjustment shaft is fixedly installed at the end of the connecting rod one away from the handle one. In this paper bag machine adjustment mechanism, the connecting rod one can drive the adjustment shaft to rotate, the adjustment shaft can transmit power to a screw one, the screw one can transmit power to the left end of a push plate one through a nut two, and the push plate one can transmit power to a side guide one through a fixing rod one and a fixing block one. However, this mechanism cannot solve the aforementioned technical problems. Utility Model Content

This mechanism allows for the simultaneous opening and closing of two pairs of mutually opening and closing mechanisms by rotating a single adjustment shaft, and also allows for relative position adjustment between one pair of mutually opening and closing mechanisms and another fixed mutually opening and closing mechanism, making operation convenient.

[0033] The first drive mechanism has a first set of shafts 7 and a third set of shafts 9; the first set of shafts 7 and the third set of shafts 9 are rotatably mounted on the frame, and lead screws are provided on the first set of shafts 7 and the third set of shafts 9.

[0035] The third drive mechanism has a first spindle 71 and a third spindle 91, which are rotatably mounted in a first set of shafts 7 and a third set of shafts 9, respectively.

[0040] Example 2

[0041] The paper bag machine adjustment mechanism comprises: a first working mechanism 1, a second working mechanism 2, a third working mechanism 3, a fourth working mechanism 4, a fifth working mechanism 5, and a sixth working mechanism 6, movably mounted on the machine frame; a first drive mechanism capable of driving the sixth working mechanism 6 to move; a second drive mechanism capable of driving the fourth working mechanism 4 and the fifth working mechanism 5 to move relative to each other, and also capable of driving the second working mechanism 2 and the third working mechanism 3 to move relative to each other; a third drive mechanism capable of driving the second working mechanism 2 and the third working mechanism 3 to move; and a fourth drive mechanism capable of driving the first working mechanism 1 to move. The adjustment method of this paper bag machine adjustment mechanism includes the following steps:

[0042] 1) The first set of shafts 7 is hollow inside and is connected to the third set of shafts 9 by a synchronous belt. It can be adjusted by a handle or by A servo drive. When the first set of shafts 7 is adjusted, the outer sleeve screw of the third set of shafts 9 moves accordingly. The third spindle 91 is connected to the third set of shafts 9 by a bearing. When the third set of shafts 9 moves, the third spindle 91 does not move. The first set of shafts 7 and the third set of shafts 9 enable the sixth working mechanism 6 to move left and right.

[0043] 2) The second set of shafts is hollow and connected to the fourth set of shafts 10 by a synchronous belt. It can be adjusted by a handle or by B servo. When the second set of shafts 8 is adjusted, the fourth set of shafts 10 moves accordingly. The fourth spindle 101 is connected to the fourth set of shafts 10 by a bearing. When the fourth set of shafts 10 moves, the fourth spindle 101 does not move. The second set of shafts 8 is connected to the positive and negative lead screws, with a transmission gear in the middle. The fourth set of shafts 10 is connected to the positive and negative lead screws, with a transmission gear in the middle. The transmission gear in the middle of the positive and negative lead screws transmits power to the intermediate transition shaft. The gear on the transition shaft transmits power to the positive and negative lead screws of the second and third sets. The second and fourth sets of shafts 10 rotate the fourth working mechanism 4 and the fifth working mechanism 5 to open and close. The second working mechanism 2 and the third working mechanism 3 also open and close at the same time.

[0044] 3) The third spindle 91 passes through the third sleeve shaft 9 and connects to the adjusting nut in the sleeve shaft opening and closing screw between the second working mechanism 2 and the third working mechanism 3. The tail end of the third spindle 91 is connected to the timing belt and the first spindle 71. The first spindle 71 is connected to the D servo. At the same time, the screw connects to the positive and negative thread screws of the upper part of the sleeve shaft of the second working mechanism 2 and the third working mechanism 3. The third spindle 91 can be adjusted by the handle or by the D servo. When the third screw is adjusted, the second working mechanism 2 and the third working mechanism 3 move left and right at the same time.

[0045] 4) The fourth spindle 101 passes through the fourth set of shafts 10 and connects to the adjusting nut of the first working mechanism 1. The tail end of the fourth spindle 101 is connected to the timing belt and the second spindle 81. The second spindle 81 is connected to the C servo. At the same time, the lead screw is connected to the adjusting nut of the first working mechanism 1. The fourth spindle 101 can be adjusted by a handle or by the C servo. Adjusting the fourth lead screw causes the first working mechanism 1 to move left and right.

[0046] In areas where the adjustment range is limited, three sets of left and right adjustments and one set of opening and closing adjustments are implemented, resulting in a small arrangement space and fewer adjustment cycles.

[0047] By adopting the above scheme, it is possible to simultaneously open and close two pairs of mutually opening and closing mechanisms by rotating one adjusting shaft. It also allows for the adjustment of the relative positions of one pair of mutually opening and closing mechanisms with another fixed mutually opening and closing mechanism, making operation convenient.
