[0002] The heat sealing and hot cutting bag making machine is a machine used to make plastic bags. During the plastic bag processing, the raw material package needs to be placed on the raw material roller and then introduced into the machine for processing. If the raw material package is placed directly on the raw material roller, there will be a certain amount of shaking, which will have a certain impact on bag making, so a fixing device is needed to fix the raw material package.

[0003] For example, a fixing device for a heat-sealing and heat-cutting bag-making machine disclosed in a Chinese patent with the publication number CN214448983U includes a device body, a support plate is fixedly connected to the upper side wall of one side of the device body, the support plate is connected to a rotating rod through a clamping mechanism, a movable groove is provided on the other side wall of the device body, the movable groove side wall is connected to a movable plate through a limiting mechanism, the movable plate side wall is provided with a connecting groove, one end of the rotating rod passes through the connecting groove side wall, the device body is provided with a rectangular groove, the rectangular groove side wall is rotatably connected to a threaded rod, one end of the threaded rod passes through the rectangular groove side wall and extends to the outside, and the threaded rod is provided with a fixing mechanism. The utility model allows the raw material bag to be installed more conveniently through the support plate, movable plate, threaded rod, sliding sleeve, fixed plate and baffle, and after installation, the rotating rod can be fixed, which effectively improves the stability of the rotating rod, thereby improving the processing quality of the plastic bag.

[0004] Some problems were found during use of the above-mentioned existing heat-sealing and heat-cutting bag-making machine fixing device. First, the raw material package is sleeved on the rotating roller, and the movable plate and the support ring can only limit the rotating roller. However, the raw material package may still swing left and right on the rotating roller when rotating, which affects the quality of plastic bag processing. Secondly, the raw material package is heavy as a whole, and it is difficult for one person to move and install it on the rotating roller. The installation of the raw material package is still difficult for one person to complete. Utility Model Content

[0022] The lifting plate 5 is moved upward by starting the cylinder 503, so that when the lifting plate 5 drops to the lowest point, one end of the slope connecting plate 502 will touch the ground. At this time, the raw material bag can be rolled onto the arc-shaped plate 501 through the slope connecting plate 502, and then the cylinder 503 is started again to drive the lifting plate 5 to move upward, so that the center hole of the lifting plate 5 is aligned with the rotating shaft 3. The movable support frame 2 can drive the rotating shaft 3 to move, so that the rotating shaft 3 is inserted into the center hole of the raw material bag, thereby completing the loading operation of the device. The raw material bag is dragged upward by the lifting plate 5 without the need for traditional manual lifting. Secondly, the conical limit plate 4 slidably sleeved on the rotating shaft 3 can resist both sides of the raw material bag, thereby limiting the left and right shaking of the raw material bag. Secondly, the conical limit plate 4 is conical as a whole, with the conical surface facing the raw material bag, so that it will be inserted into the center hole of the raw material bag, avoiding the problem that the center hole of the raw material bag is larger than the rotating shaft 3 and the raw material bag rotates up and down.

[0023] Among them, in order to achieve the purpose of adjusting the distance between the support frames 2, the present device is implemented by adopting the following technical scheme: a bidirectional threaded shaft 102 is rotatably installed in the dovetail slide groove 101, an adjusting motor 103 is fixedly installed on one side of the base 1, the output end of the adjusting motor 103 is fixedly connected to the bidirectional threaded shaft 102, and a second threaded through hole 202 is opened in the dovetail slider 201, and the second threaded through hole 202 is threadedly matched with the bidirectional threaded shaft 102.

[0024] By starting the adjusting motor 103, the bidirectional threaded shaft 102 can be driven to rotate. The bidirectional threaded shaft 102 is threadedly matched with the second threaded through hole 202, so that the rotation of the bidirectional threaded shaft 102 can drive the two dovetail sliders 201 to move closer to or away from each other. The movement of the dovetail slider 201 can drive the support frame 2, thereby adjusting the distance between the two support frames 2, so that the rotating shaft 3 can be inserted into the center hole of the raw material package.

[0025] Among them, in order to achieve the purpose of adjusting the position of the conical limit disk 4, the present device is implemented by adopting the following technical scheme: a limit slide groove 301 is opened in the rotating shaft 3, an adjusting shaft 302 is rotatably installed in the limit slide groove 301, an inner hexagonal groove 303 is opened at one end of the adjusting shaft 302, a limit slider 401 is fixedly installed in the central hollow of the conical limit disk 4, a second limit slide groove 402 is opened in the limit slider 401, and the second limit slide groove 402 is threadedly matched with the adjusting shaft 302.

[0026] The adjusting shaft 302 can be rotated with a hexagonal wrench through the inner hexagonal groove 303, and the adjusting shaft 302 is threadedly matched with the second limiting slide groove 402, so that the rotation of the adjusting shaft 302 can drive the limiting slider 401 to move, and the movement of the limiting slider 401 can drive the conical limiting disk 4 to move, thereby adjusting the position of the conical limiting disk 4 so that the conical limiting disk 4 can clamp raw material packages of different widths.

[0027] The working principle and use process of the utility model: when in use, the device needs to be fixed on the input side of the hot cutting bag making machine. First, it is necessary to use a hexagonal wrench to rotate the adjusting shaft 302 according to the width of the raw material package. The rotation of the adjusting shaft 302 can drive the limit slider 401 to move, and the movement of the limit slider 401 can drive the conical limit disk 4 to move. Adjust the conical limit disk 4 to a suitable position, and then roll the raw material package onto the arc-shaped support plate 501 through the slope connecting plate 502, and then start the cylinder 503 again to drive the lifting support plate 5 to move up, so that the center hole of the lifting support plate 5 is aligned with the rotating shaft 3, start the adjusting motor 103 to drive the support frame 2 to move, and the support frame 2 can drive the rotating shaft 3 to move, so that the rotating shaft 3 is inserted into the center hole of the raw material package. At the same time, the conical limit disk 4 will be squeezed on both sides of the raw material package, effectively fixing the raw material package on the rotating shaft 3, and completing the feeding and fixing operation of the raw material package.
