Description

Technical Field

[0001] This utility model belongs to the field of garbage bag production technology, specifically relating to a bag-making and stabilizing cutting device. Background Technology

[0002] As the name suggests, garbage bags are bags for holding garbage. These small bags bring great convenience to thousands of households, provide important protection for the environment, and even facilitate garbage recycling and sorting. In the production and preparation of garbage bags, the rolled garbage bags need to be cut.

[0003] A prior art patent, CN223101627U, discloses a cutting device for garbage bags. This patent includes a cutting frame, inside which are installed lifting rollers and fixed rollers. A garbage bag unwinding roller is installed on one side of the cutting frame, and a supporting beam is installed on the other side. A cutting drive cylinder is mounted on the upper surface of the supporting beam, and the output end of the cutting drive cylinder is fixedly connected to a lifting platform via a telescopic rod. A cutting blade is provided on the lower surface of the lifting platform. This device utilizes a cutting... The drive cylinder controls the lifting platform to move downwards stably, causing the cutting blade to cut the garbage bag, which has the advantage of convenient cutting operation; however, there are still the following shortcomings in actual use: In practice, when the device is cutting, the cutting blade descends and squeezes against the worktable to cut the workpiece. The contact and impact between the cutting blade and the worktable during descent causes wear on the surface of the worktable. Over time, the surface of the worktable will gradually be damaged, and may even develop dents and cracks. The wear on the surface will not only affect the flatness of the worktable, but may also affect the accuracy and quality of bag cutting.

[0004] Therefore, a stable bag-cutting device is needed to solve the problem in the existing technology where the cutting blade is in long-term contact with and impacts on the worktable, causing damage to the worktable and affecting the cutting accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a stable bag-cutting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bag-making and stabilizing bag-cutting device, comprising a base plate, a support seat fixedly connected to the top of the base plate, a worktable fixedly connected to the top of the support seat, two first brackets fixedly connected to one side of the worktable, two guide rollers rotatably connected between the two first brackets, two second brackets fixedly connected to the other side of the worktable, two take-up rollers rotatably connected between the two second brackets, two first drive motors corresponding to the take-up rollers fixedly connected to the front end of one of the second brackets, and a cutting mechanism provided at the middle position of the top of the worktable.

[0007] It should be noted in the solution that the top of the base plate has multiple positioning holes.

[0008] It is worth noting that the workbench has a rounded chamfer design on its perimeter.

[0009] It should be further noted that the output ends of the two first drive motors are respectively fixedly connected to the take-up roller, and the two first drive motors rotate in opposite directions.

[0010] In a preferred embodiment, the cutting mechanism includes a mounting plate fixedly connected to the center of the top of the workbench. A support plate is fixedly connected to the top of the mounting plate, and a through groove is formed on the surface of the support plate. Limiting slide rails are fixedly connected to the front end of the support plate near the top and bottom positions. Sliding plates are slidably connected to the front ends of the two limiting slide rails. Connecting blocks are fixedly connected to the front ends of the two sliding plates. Cutting blades are fixedly connected to the surfaces of the two connecting blocks. Two connecting plates are rotatably connected to the front end of the support plate. A first arc-shaped guide groove and a second arc-shaped guide groove are formed inside the two connecting plates. Two gears are rotatably connected to the front end of the support plate. A first guide post is fixedly connected to the front end of the two gears. A second guide post is fixedly connected to the front end of the two connecting blocks. A second servo motor is fixedly connected to the rear end of the support plate.

[0011] In a preferred embodiment, the two cutting blades are designed symmetrically.

[0012] In a preferred embodiment, the two first guide posts slide on the inner wall of the corresponding first arc-shaped guide groove, and the two second guide posts slide on the inner wall of the corresponding second arc-shaped guide groove.

[0013] In a preferred embodiment, the output end of the second servo motor is fixedly connected to one of the gears through the support plate, and the two gears mesh with each other.

[0014] Compared with the prior art, the bag-making and bag-cutting device provided by this utility model has at least the following beneficial effects:

[0015] (1) Through the symmetrical cutting design of the cutting mechanism, the two cutting blades are driven by the second servo motor and guided by the gear meshing transmission and the arc-shaped guide groove of the connecting plate to achieve opposite movement to cut the garbage bag, instead of the traditional blade pressing down to hit the worktable for cutting. This cutting method can avoid the cutting blades directly contacting and hitting the worktable, preventing wear, dents or cracks on the worktable surface, ensuring the long-term flatness of the worktable, thus maintaining the stability of the bag cutting accuracy and reducing cutting quality problems caused by damage to the worktable.

[0016] (2) By setting two winding rollers, garbage bags can be stably conveyed under the drive of the first drive motor. This works in synergy with the shearing action of the cutting mechanism, which can adapt to the cutting requirements of garbage bags of different thicknesses and widths, while meeting the continuous production rhythm and improving the overall bag making and cutting efficiency.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4This utility model provides a bag making and stabilizing bag cutting device, including a base plate 1, a support base 2 fixedly connected to the top of the base plate 1, a worktable 3 fixedly connected to the top of the support base 2, two first brackets 4 fixedly connected to one side of the worktable 3, two guide rollers 5 rotatably connected between the two first brackets 4, two second brackets 6 fixedly connected to the other side of the worktable 3, two take-up rollers 7 rotatably connected between the two second brackets 6, two first drive motors 8 corresponding to the take-up rollers 7 fixedly connected to the front end of one of the second brackets 6, and a cutting mechanism 9 is provided at the middle position of the top of the worktable 3.

[0024] Further as Figure 1 and Figure 2 As shown, it is worth noting that the top of the base plate 1 has multiple positioning holes. These multiple positioning holes can provide multiple standardized mounting points, making it easier and more accurate to fix the device on the mounting surface, thereby improving the efficiency and accuracy of installation.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth noting that the workbench 3 has a rounded chamfer design on all sides. The rounded chamfer design can eliminate sharp corners and reduce the risk of injury to the operator when contacting the edge of the workbench 3 during operation. This is especially important in the case of fast or frequent operation, which improves safety. At the same time, the chamfer design can reduce wear when the edge is subjected to external impact or friction, which helps to extend the service life of the workbench 3, especially in long-term or high-intensity working environments.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that the output ends of the two first drive motors 8 are fixedly connected to the winding rollers 7 respectively, and the two first drive motors 8 rotate in opposite directions, ensuring that the two first drive motors 8 can drive the two winding rollers 7 to rotate in opposite directions at the same time, thereby winding up the cut garbage bags, replacing the traditional manual winding and improving work efficiency.

[0027] As can be seen from the above working process, by setting two winding rollers 7, the garbage bags can be stably conveyed under the drive of the first drive motor 8, and the shearing action of the cutting mechanism 9 can be coordinated to adapt to the cutting needs of garbage bags of different thicknesses and widths, while meeting the continuous production rhythm and improving the overall bag making and cutting efficiency.

[0028] Further as Figure 3 and Figure 4As shown, it is worth noting that the cutting mechanism 9 includes a mounting plate 901 fixedly connected to the top center of the workbench 3. A support plate 902 is fixedly connected to the top of the mounting plate 901. A through groove 903 is formed on the surface of the support plate 902. Limiting slide rails 904 are fixedly connected to the front end of the support plate 902 near the top and bottom positions. Sliding slides 905 are slidably connected to the front ends of the two limiting slide rails 904. Connecting blocks 906 are fixedly connected to the front ends of the two sliding slides 905. Cutting blades 907 are fixedly connected to the surface of the two connecting blocks 906. Two connecting plates 908 are rotatably connected to the front end of the support plate 902. A first arc-shaped guide groove 909 and a second arc-shaped guide groove 910 are formed inside the two connecting plates 908. Two gears 911 are rotatably connected to the front end of the support plate 902. The front end of each gear 911 is fixedly connected to a first guide post 912, and the front end of each of the two connecting blocks 906 is fixedly connected to a second guide post 913. The rear end of the support plate 902 is fixedly connected to a second servo motor 914. Through the symmetrical cutting design of the cutting mechanism 9, the two cutting blades 907, driven by the second servo motor 914, move in opposite directions to cut the garbage bag by means of gear 911 meshing transmission and the arc-shaped guide groove of the connecting plate 908. Instead of the traditional blade pressing down to strike the worktable, this cutting method avoids direct contact and impact between the cutting blades 907 and the worktable 3, preventing wear, dents or cracks on the surface of the worktable 3, ensuring the long-term flatness of the worktable, and thus maintaining stable bag cutting accuracy and reducing cutting quality problems caused by damage to the worktable 3.

[0029] Further as Figure 3 and Figure 4 As shown, it is worth noting that the two cutting blades 907 are symmetrically designed. This symmetrical design allows the two cutting blades 907 to apply force evenly during the cutting process, avoiding excessive force on one side. This helps to improve the accuracy and quality of the cutting and reduce uneven wear of the blades.

[0030] Further as Figure 3 and Figure 4 As shown, it is worth noting that the two first guide posts 912 slide on the inner wall of the corresponding first arc-shaped guide groove 909, and the two second guide posts 913 slide on the inner wall of the corresponding second arc-shaped guide groove 910. Due to the cooperation of the guide posts and guide grooves, the cutting blade 907 can move smoothly and accurately, thereby improving the cutting efficiency, reducing the adjustment time caused by deviation or instability, and making the production efficiency higher.

[0031] Further as Figure 3 and Figure 4As shown, it is worth noting that the output end of the second servo motor 914 is fixedly connected to one of the gears 911 through the support plate 902, and the two gears 911 mesh with each other, ensuring that the second servo motor 914 can drive one of the gears 911 to rotate smoothly. The meshing design allows the two gears 911 to rotate in opposite directions at the same time.

[0032] This solution has the following working process: In actual use, the garbage bag material roll to be cut is placed at the feeding end of the device. The two first drive motors 8 are started. Since the two first drive motors 8 rotate in opposite directions, their output ends drive the two winding rollers 7 to rotate in opposite directions, pulling the garbage bag material through the two guide rollers 5 in sequence, so that the material is flatly conveyed to the cutting mechanism 9 at the top of the workbench 3, completing the material positioning before cutting; The second servo motor 914 in the cutting mechanism 9 is started. Its output end passes through the support plate 902 and drives one of the gears 911 to rotate. Since the two gears 911 mesh, they drive the other gear 911 to rotate synchronously in opposite directions. The first guide roller at the front end of each gear 911... The column 912 slides along the first arc-shaped guide groove 909 of the corresponding connecting plate 908, driving the connecting plate 908 to rotate. When the connecting plate 908 rotates, its second arc-shaped guide groove 910 drives the connecting block 906 and the slide plate 905 to slide towards each other along the limiting slide rail 904 through the second guide column 913, so that the two symmetrically designed cutting blades 907 close and cut, completing a single garbage bag cutting. After the cutting is completed, the second servo motor 914 drives the gear 911 to rotate in the opposite direction. Through the above transmission structure, the two cutting blades 907 are reset. At the same time, the winding roller 7 continuously pulls the garbage bag raw material forward to convey a set distance, repeating the above cutting action to achieve continuous and stable cutting of garbage bags until mass production is completed.

[0033] In summary: By setting two take-up rollers 7, which are driven by the first drive motor 8, the garbage bags can be stably conveyed. This works in conjunction with the shearing action of the cutting mechanism 9, adapting to the cutting needs of garbage bags of different thicknesses and widths, while meeting the requirements of continuous production and improving the overall efficiency of bag making and cutting. Through the symmetrical cutting design of the cutting mechanism 9, the two cutting blades 907, driven by the second servo motor 914, achieve opposite motion to cut the garbage bags by means of gear 911 meshing transmission and the arc-shaped guide groove of the connecting plate 908. This is a different method than the traditional blade pressing down and hitting the worktable. This shearing method avoids direct contact between the cutting blades 907 and the worktable 3, preventing wear, dents or cracks on the surface of the worktable 3, ensuring the long-term flatness of the worktable, and thus maintaining stable cutting accuracy and reducing cutting quality problems caused by damage to the worktable 3.

[0034] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
