Description

Technical Field

[0001] This utility model relates to the field of packaging bag slitting machine technology, specifically a packaging bag slitting machine that is easy to position. Background Technology

[0002] Packaging bags are bags used to package various goods, facilitating transportation and storage during production and distribution. They are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags end up in landfills like regular waste, with only 7% being recycled.

[0003] After the packaging bags are produced, a slitting machine is needed to cut them into suitable sizes for convenient use. However, the current slitting machine uses a take-up sleeve on the surface of the take-up roller. As the take-up roller rotates, the take-up sleeve will shift on its surface, which will affect the subsequent take-up effect. Utility Model Content

[0004] The purpose of this utility model is to provide a packaging bag cutting machine that is easy to position, so as to solve the problems existing in the above-mentioned background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging bag slitting machine for convenient positioning, comprising a slitting machine body, a winding roller for sleeved onto a winding sleeve, and a limiting mechanism for limiting the two winding rollers, further comprising:

[0006] A fixed plate is fixedly connected to the upper and lower sides of the inner side of the slitting machine body. Slide grooves are provided on both sides of the top of the fixed plate. A first folding plate is movably connected inside the slide groove on the right side. The bottom end of the first folding plate extends to the bottom of the fixed plate and is fixedly connected to a first positioning ring. The inside of the first positioning ring is movably connected to the surface of the take-up roller.

[0007] A second folded plate is movably connected inside the slide groove on the left side. A screw is threadedly connected to the bottom end of the second folded plate. A torsion plate is fixed to one end of the screw, and a connecting block is rotatably connected to the other end of the screw. A second positioning ring is fixed to the surface of the connecting block.

[0008] Preferably, a fixing rod is fixedly connected inside both the left and right slides, and the surfaces of the two fixing rods are movably connected to the interior of the second folded plate and the interior of the first folded plate, respectively.

[0009] Preferably, the surfaces of one end of the first folding plate and the surfaces of one end of the second folding plate are threadedly connected with fastening bolts for fixing them to the surface of the fixing plate.

[0010] Preferably, a movable rod is fixedly connected to the back of the second positioning ring, and the surface of the other end of the movable rod is movably connected to the interior of one end of the second folded plate.

[0011] Preferably, the second positioning ring is arc-shaped, and the inner side of the second positioning ring is movably connected to the surface of the take-up roller.

[0012] Preferably, the surface of the take-up roller is provided with an anti-slip sleeve, and the take-up sleeve is fitted onto the surface of the anti-slip sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When the take-up sleeve is fitted onto the surface of the take-up roller, the first positioning ring moves with the first folding plate, allowing the first positioning ring to fit and limit the right side of the limiting sleeve. As the second folding plate moves the connecting block and the second positioning ring to the right, the second positioning ring can fit and limit the left side of the take-up sleeve. This not only positions the take-up sleeve fitted onto the surface of the take-up roller, but also prevents the packaging bag from shifting during take-up. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, a convenient positioning packaging bag slitting machine includes a slitting machine body 1. A take-up roller 2 is provided on both the upper and lower sides of the inner side of the slitting machine body 1 for fitting a take-up sleeve. An anti-slip sleeve 15 is provided on the surface of the take-up roller 2, and the take-up sleeve is fitted onto the surface of the anti-slip sleeve 15. This increases the friction between the take-up sleeve and the take-up sleeve, preventing the take-up sleeve from moving arbitrarily. A limiting mechanism 3 is provided inside the left side of the slitting machine body 1 for limiting the two take-up rollers 2. A fixing plate 4 is fixedly connected to both the upper and lower sides of the inner side of the slitting machine body 1. Sliding grooves 5 are provided on both sides of the top of the fixing plate 4. A first folding plate 6 is movably connected inside the right sliding groove 5. The bottom end of the first folding plate 6... A first positioning ring 7 extends to the bottom of the fixed plate 4 and is fixedly connected. The interior of the first positioning ring 7 is movably connected to the surface of the take-up roller 2. A second folding plate 8 is movably connected to the interior of the left side slide groove 5. A screw 9 is threadedly connected to the bottom end of the second folding plate 8. A torsion plate 10 is fixed to one end of the screw 9, and a connecting block 11 is rotatably connected to the other end of the screw 9. A second positioning ring 12 is fixed to the surface of the connecting block 11. The second positioning ring 12 is arc-shaped, and the inner side of the second positioning ring 12 is movably connected to the surface of the take-up roller 2. This allows the second positioning ring 12 to move on the surface of the take-up roller 2, so as to facilitate the subsequent positioning of the take-up sleeve fitted on the surface of the take-up roller 2.

[0022] The interior of each of the left and right sliding grooves 5 is fixedly connected with a fixing rod 14, and the surfaces of the two fixing rods 14 are movably connected to the interior of the second folded plate 8 and the interior of the first folded plate 6, respectively. In this way, the second folded plate 8 and the first folded plate 6 can be provided with auxiliary support and maintain their stability when moving.

[0023] Both the surface of one end of the first folding plate 6 and the surface of one end of the second folding plate 8 are threadedly connected with fastening bolts 16 for fixing them to the surface of the fixing plate 4. Thus, after the positions of the first folding plate 6 and the second folding plate 8 are moved, the fastening bolts 16 can be rotated to easily fix their moved positions.

[0024] The back of the second positioning ring 12 is fixedly connected to a movable rod 13. The surface of the other end of the movable rod 13 is movably connected to the interior of one end of the second folded plate 8. This allows for auxiliary positioning of the second positioning ring 12, facilitating its forward and backward movement.

[0025] It is worth noting that the technical features proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0026] Working principle: In use, the limiting mechanism 3 can be used to release the limit on the take-up roller 2, and then the take-up sleeve can be placed on the surface of the take-up roller 2. After placement, the limiting mechanism 3 can be used to fix the take-up roller 2 again. Then, the fastening bolt 16 on the surface of the first folding plate 6 can be rotated to release the limit on the first folding plate 6. Subsequently, the first folding plate 6 and the first positioning ring 7 are moved to the left, so that the first positioning ring 7 can fit and position the right side of the take-up sleeve. Then, the fastening bolt 16 on the surface of the second folding plate 8 can be rotated to release the limit on the second folding plate 8. The limiting mechanism 3 moves the second folding plate 8 to the right, causing the second positioning ring 12 to follow, thereby positioning the left end of the take-up sleeve. After take-up, the take-up sleeve can be removed. If the take-up sleeve needs to be removed after take-up, the limiting mechanism 3 can be used to release the limiting on the take-up roller 2. Then, the torsion disc 10 is rotated, and the screw 9 is rotated. At the same time, the connecting block 11 and the second positioning ring 12 are moved backward, so that the second positioning ring 12 releases the limiting on the take-up sleeve on the surface of the take-up roller 2. Finally, the take-up sleeve can be removed.
