Description

Technical Field

[0001] This utility model relates to the technical field of cutting, specifically to a packaging bag corner cutting device. Background Technology

[0002] Plastic packaging bags are mass-produced through production lines in the workshop. After the shaping process, the material needs to be cut into the corresponding specifications. Plastic packaging bags require heat sealing, cutting and other manufacturing processes during production. The cutting process requires the use of cutting equipment.

[0003] For example, Chinese Patent Publication No. CN217046586U discloses a cutting device for processing packaging bags, relating to the technical field of cutting devices. It includes a base and a first fixed frame, with the first fixed frame fixed to the base. A cutting mechanism is installed inside the first fixed frame, and clamping mechanisms are installed at both ends of the top of the base. The cutting mechanism includes an electric telescopic rod and a movable rod, with the electric telescopic rod fixed to the middle of the top side inside the first fixed frame. This utility model, by providing a base and clamping mechanisms at both ends of the top of the base, can clamp and fix the opening and body of the packaging bag, preventing movement during the cutting process. By providing a first fixed frame and installing the cutting mechanism inside it, the cutting mechanism can move in two dimensions, thus cutting the packaging bag. This eliminates the need for workers to manually cut the packaging bag with a hand-held cutting machine.

[0004] Because some packaging bags are made of soft materials, the existing devices use high-speed rotating blades to cut the bags, which may result in a less smooth cut surface, affecting the accuracy of the packaging bags and potentially causing them to fail to meet factory standards. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a packaging bag corner cutting device that improves the stability of the device during packaging bag cutting operations, improves the flatness of the cutting of packaging bags, improves the subsequent use effect of packaging bags, and improves practicality.

[0006] This utility model discloses a packaging bag edge cutting device, including a cutting table, two guard plates, and a top plate. The two guard plates are symmetrically fixedly installed on the top of the cutting table, and the top plate is fixedly connected to the top of the two guard plates. Two clamping mechanisms are provided between the two guard plates. The clamping mechanism includes two sliding plates. Limiting holes are opened on the outer side walls of the guard plates, and the sliding plates are slidably connected to the limiting holes. A rotating shaft is rotatably installed on each of the two sliding plates, and a pressure roller is rotatably installed on the outer side wall of the rotating shaft. A fixed platform is fixedly installed on the top of the cutting table, and a through hole is opened on the fixed platform. The bottom end of each sliding plate is fixedly connected to the top of the cutting table by a spring. A movable plate is slidably installed between the two top plates, and a support plate is fixedly installed on the bottom end of the movable plate. A first blade is fixedly installed on the bottom area of ​​the support plate by a fixing mechanism.

[0007] Multiple second blades are symmetrically fixed to the bottom of the first blade. This packaging bag corner cutting device, through the extension and contraction of springs, synchronously drives the slide plate, rotating shaft, and pressure roller to move longitudinally under the limitation of the limiting hole. The outer wall of the pressure roller is tightly attached to the packaging bag, thus completing the fixing operation of the packaging bag. The moving plate moves simultaneously with the support plate and the first blade. The movement of the first blade drives the movement of the second blade simultaneously. The bottom end of the second blade first contacts the packaging bag, and then performs a preliminary cutting operation on the packaging bag. After that, the first blade contacts the packaging bag again. The rotating shaft rotates simultaneously with the pressure roller. The rotating pressure roller guides the cut packaging bag, thereby improving the stability of the device during the packaging bag cutting operation, improving the flatness of the cut packaging bag, improving the subsequent use effect of the packaging bag, and improving practicality.

[0008] Preferably, two upright plates are symmetrically fixedly installed on the top of the cutting table, and a movable block is slidably installed on each upright plate. The two movable blocks are fixedly connected by a baffle. The movable blocks slide on the top of the upright plates, which facilitates the synchronous movement of the baffle. The baffle contacts the packaging bags, which allows for the measurement and positioning of packaging bags of different sizes.

[0009] Preferably, a scale is fixedly installed on the outer wall of the upright plate, which facilitates the judgment of the size of the packaging bag.

[0010] Preferably, a guide seat is fixedly installed at the top of the fixed platform, and a fixed groove is opened at the top of the guide seat. Multiple rotating rollers are installed in parallel and rotatably on the fixed groove. The packaging bag is attached to the rotating rollers, which facilitates the movement of the packaging bag at the top of the fixed platform.

[0011] Preferably, a cylinder is fixedly installed at the top of the top plate, and the output end of the cylinder is fixedly connected to the top of the moving plate. By installing the cylinder, it is convenient to provide power support to the moving plate.

[0012] Preferably, the top of the cutting table is provided with a slot, and a collection slot is slidably installed on the slot. By installing the slot and the collection slot, it is convenient to collect the cut packaging bags.

[0013] Preferably, a guide plate is fixedly installed on the top of the cutting table, and multiple guide rods are fixedly installed on the top of the collection trough. By installing the collection trough and guide rods, it is convenient to guide the cut packaging bags.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This packaging bag corner cutting device, through the extension and contraction of the spring, synchronously drives the sliding plate, rotating shaft and pressure roller to move longitudinally under the limitation of the limiting hole. The outer wall of the pressure roller is tightly attached to the packaging bag, thereby completing the fixing operation of the packaging bag. The moving plate moves simultaneously, driving the support plate and the first blade to move. The first blade moves simultaneously, driving the second blade to move. The bottom end of the second blade first contacts the packaging bag, and then performs a preliminary cutting operation on the packaging bag. After that, the first blade contacts the packaging bag again. The rotating shaft rotates simultaneously, driving the pressure roller to rotate. The rotating pressure roller guides the cut packaging bag, thereby improving the stability of the device during the packaging bag cutting operation, improving the flatness of the cutting of the packaging bag, improving the subsequent use effect of the packaging bag, and improving practicality.
