[0044] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0045] like Figure 1-7As shown, an embodiment of the utility model provides a roll bag production device with the function of changing shafts without stopping the machine, including a frame 10, which serves as the basic support of the roll bag production device with the function of changing shafts without stopping the machine, and the frame 10 includes two opposite side walls 11, and a friction wheel 12 is arranged between the two side walls 11. Upper bracket mechanisms 20 are also arranged on the frame 10, and two upper bracket mechanisms 20 are provided. Each upper bracket mechanism 20 is respectively arranged on the two side walls 11, and each upper bracket mechanism 20 includes an upper bracket swing arm 21, and the upper bracket swing arm 21 is rotatably arranged on the side wall 11. A first accommodating groove 22 is arranged on the swing arm of each upper bracket, and the two first accommodating grooves 22 are used to place the spare air expansion shaft M. The upper bracket swing arm 21 can swing, and the swing trajectory of the first accommodating groove 22 located on the upper bracket swing arm 21 is a section of a circle. Under the action of the first accommodating groove 22, the swing trajectory of the spare air expansion shaft M and the contour of the friction wheel 12 have a first intersection, that is, the spare air expansion shaft M swings to the first intersection, and the spare air expansion shaft M is tangent to the friction wheel 12. The first intersection is in front of the friction wheel 12.

[0046] The roll bag production device with the function of changing the shaft without stopping the machine also includes two lower bracket mechanisms 30, which are arranged in front of the friction wheel 12, and each lower bracket mechanism 30 includes a lower bracket seat 31, which moves along the up and down direction, and the lower bracket seat 31 is used to temporarily support the spare air expansion shaft M. A roll unloading mechanism 40 is also arranged in front of the lower bracket. Similarly, the roll unloading mechanism 40 includes two unloading forks 41, and each unloading fork 41 is provided with a second accommodating groove 42, and the unloading fork 41 is rotatably arranged on the side wall 11. A central winding mechanism 50 is also arranged between the unloading mechanism 40 and the lower bracket mechanism 30. There are two central winding mechanisms 50, each of which includes a winding fork 51. The winding fork 51 is rotatably arranged on the side wall 11. A third accommodating groove 52 is arranged on the winding fork 51. The winding fork 51 can swing. The swing path of the third accommodating groove 52 on the winding fork 51 has a second intersection with the motion trajectory of the lower bracket seat 31 and a third intersection with the motion trajectory of the unloading fork 41.

[0047] The roll bag production device with the function of non-stop shaft changing also includes a film cutting mechanism 60, which includes a cutting unit 61. The movement trajectory of the cutting unit 61 intersects with the movement trajectory of the winding fork 51 and has a fourth intersection point, which is located between the winding fork 51 and the lower bracket mechanism 30.

[0048] Preferably, the spare air expansion shaft M is coated with an adhesive.

[0049] The spare air expansion shaft M is placed on the upper bracket mechanism 20, and the spare air expansion shaft M is supported and restricted by the first accommodating groove 22. This position is the spare station. The working air expansion shaft M rotates and winds the roll bag at the second intersection. This position is the working station. After the roll bag of a preset length is wound, the winding fork 51 drives the air expansion shaft M to swing from the second intersection to the third intersection. Figure 8 As shown, during the swinging process, the inflatable shaft M moves horizontally along the upper edge of the side wall 11 under the manipulation of the winding fork 51, the film cutting mechanism 60 cuts off the roll bag, and the inflatable shaft M disengages from the winding fork 51 at the third intersection and enters the second accommodating groove 42 on the unloading fork 41. The unloading fork 41 continues to rotate in the direction away from the third intersection to unload the inflatable shaft M with the roll bag.

[0050] When the winding fork 51 rotates toward the third intersection, the upper bracket swing arm 21 rotates, the first accommodating groove 22 rotates downward, the spare air expansion shaft M located in the first accommodating groove 22 disengages from the first accommodating groove 22, and fits with the friction wheel 12 at the first intersection. Driven by the friction wheel 12, the spare air expansion shaft M rotates slightly, so that the starting end of the cut roll bag is bonded to the air expansion shaft M.

[0051] When the upper bracket swing arm 21 swings downward, the lower bracket seat 31 moves upward to support the spare air expansion shaft M, and the winding fork 51 returns from the third intersection to the second intersection. At this time, the height of the upward movement of the lower bracket seat 31 is higher than the second intersection. After the winding fork 51 swings to the second intersection, the lower bracket seat 31 turns to move downward. During the downward movement, the two ends of the spare air expansion shaft M fall into the third accommodating groove 52 of the winding fork 51. As the lower bracket seat 31 continues to move downward, the spare air expansion shaft M is separated from the lower bracket seat 31 and supported by the upper edge of the side wall 11. That is, although the spare air expansion shaft M falls into the third accommodating groove 52 at this time, it is limited by the support of the side wall 11 and the spare air expansion shaft M is suspended in the third accommodating groove. At this time, the spare air expansion shaft M located in the third accommodating groove 52 rotates as the working air expansion shaft M and continues to wind the roll bag, thereby realizing the replacement of the air expansion shaft M without stopping the machine.

[0052] In the present application, only a spare air expansion shaft M and a working air expansion shaft M are required to realize automatic replacement without stopping the machine, which simplifies the workload of replacing the air expansion shaft M.
