Detailed Implementation
[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-5 This utility model provides a technical solution:
[0031] A bag-making machine cutting device includes a cutting table 1. Support rods 2 are fixedly installed at the corners of the cutting table 1. A top plate 3 is fixedly installed at the top of each support rod 2. A pair of symmetrical electric push rods 4 are fixedly installed on the bottom surface of the top plate 3. A pressure plate 5 is fixedly installed at the output shaft end of each electric push rod 4. A pair of evenly distributed electric push rods 6 are fixedly installed on the bottom surface of the top plate 3. A horizontal plate 7 is fixedly installed at the output shaft end of each electric push rod 6. A cutter 8 is provided on the bottom surface of the horizontal plate 7. A pair of symmetrical electric push rods 9 are provided on the bottom surface of the top plate 3. A pressure plate 10 is fixedly installed at the output shaft end of each electric push rod 9. A pair of symmetrical electric telescopic columns 11 are fixedly installed on one side of the top plate 3. A pair of symmetrical slide rails 12 are provided on the bottom surface of the top plate 3. Movable blocks 13 are slidably arranged on each slide rail 12. Each electric push rod 9 is fixedly installed to a movable block 13. The output shaft ends of each electric telescopic column 11 are fixedly installed to the sides of the movable blocks 13.
[0032] In the bag making machine cutting device, the cutting table 1, the support rod 2, and the top plate 3 are used to support the entire device;
[0033] When cutting the film bag, the conveying equipment transports the film bag to the cutting table. The electric push rod 4 on the bottom surface of the top plate 3 is activated, and its output shaft extends, driving the pressure plate 5 to move vertically downward, pressing one end of the film bag onto the cutting table 1. The electric push rod 9 is activated, and its output shaft extends, driving the pressure plate 10 to move vertically downward and press it onto the film bag. Then, the electric telescopic column 11 on the side of the top plate 3 is activated. The output shaft of the electric telescopic column 11 moves and pushes the movable block 13 to slide on the slide rail 12. The sliding of the movable block 13 drives the electric push rod 9 and the pressure plate 10 to move away from the electric push rod 6. During the movement of the pressure plate 10, the pressed film bag is straightened, effectively eliminating wrinkles and bends generated during the conveying process. Subsequently, the electric push rod 6 is activated, and its output shaft extends, driving the horizontal plate 7 and the cutter 8 set on the bottom surface of the horizontal plate 7 to move vertically downward, cutting the straightened film bag and ensuring that the bag is flat during cutting.
[0034] By repeating the above process, the film bag can be continuously straightened and cut.
[0035] This bag-making machine's cutting device can straighten the film bag before cutting, effectively eliminating wrinkles and bends generated during the conveying process, ensuring that the bag is flat during cutting, thereby improving cutting accuracy, reducing the defect rate, and making it highly practical.
[0036] Both pressure plate 5 and pressure plate 10 have pads on their bottom surfaces, and the pads are made of rubber.
[0037] Both pressure plate 5 and pressure plate 10 have rubber pads on their bottom surfaces. During the pressing process, these pads prevent direct hard contact between pressure plate 5 and pressure plate 10 and the film bag, thus protecting the film bag. At the same time, the rubber material has a certain friction, which increases the friction between the pressure plate and the film bag, making the film bag more stable during the straightening process and less prone to displacement, thereby improving the stability of the film bag during the straightening process.
[0038] The edge of the cutting table 1 away from the cutter 8 is set as a bevel, and a collection frame 14 is provided on the cutting table 1 at the bevel.
[0039] After the cutter 8 finishes cutting the film bag, the electric telescopic column 11 continues to drive the pressure plate 10 to move, moving the film bag to the inclined side of the shearing table. Under the influence of gravity, the film bag slides down the inclined side. The collection frame 14 set at the inclined side can receive the sliding film bag, realizing automatic feeding. There is no need for manual collection of the cut film bags, which effectively improves the cutting efficiency and makes the whole bag making and cutting process smoother.
[0040] The collection box 14 is snapped onto the side of the cutting table 1;
[0041] The collection box 14 is snapped onto the side of the cutting table 1. After a certain number of film bags have been collected in the collection box 14, the staff can easily remove the collection box 14 from the side of the cutting table 1 by separating the snap joint. This allows for convenient and quick cutting of the film bags in the collection box 14. After cutting, the collection box 14 can be snapped back onto the side of the cutting table 1 to continue receiving the subsequent cut film bags, thus improving the convenience of cutting the film bags from the collection box 14.
[0042] The bottom surface of the horizontal plate 7 has evenly distributed movable openings 15. Each movable opening 15 is provided with a spring 16, and each movable opening 15 is slidably provided with a movable rod 17. The spring 16 is pressed between the horizontal plate 7 and the movable rod 17, and the bottom end of the movable rod 17 is fixedly installed with the cutter 8.
[0043] When the electric push rod 6 drives the horizontal plate 7 and the cutter 8 to move downward to cut the film bag, the cutter 8 is subjected to resistance from the cutting table 1. The resistance is transmitted to the spring 16 in the movable opening 15 through the movable rod 17. The spring 16 deforms and buffers the cutter 8, reducing the impact force on the cutter 8 and thus improving the service life of the cutter 8.
[0044] The size of the movable rod 17 is adapted to the size of the movable opening 15, and a damping is provided between the movable rod 17 and the movable opening 15;
[0045] The size of the movable rod 17 is adapted to the size of the movable opening 15, ensuring that the movable rod 17 can slide smoothly up and down within the movable opening 15. At the same time, the damping set between the two prevents the movable rod 17 from shaking arbitrarily during the sliding process. When the cutter 8 is performing the cutting work, the movable rod 17 can stably support the cutter 8. The cutter 8 cuts the film bag in a stable state, which can ensure that the film bag will not be displaced due to the shaking of the cutter 8 during the cutting process, thereby improving the stability of the film bag during cutting and ensuring the cutting quality.
[0046] A controller is provided on the side of the cutting table 1. The controller is electrically connected to electric push rod 4, electric push rod 6, electric push rod 9, and electric telescopic column 11.
[0047] A controller is installed on the side of the cutting table 1, which can automatically control each component of the device, thereby automatically controlling the straightening and cutting process of the film bag.
[0048] Working principle:
[0049] In the bag making machine cutting device, the cutting table 1, the support rod 2, and the top plate 3 are used to support the entire device;
[0050] When cutting the film bag, the conveying equipment transports the film bag to the cutting table. The electric push rod 4 on the bottom surface of the top plate 3 is activated, and its output shaft extends, driving the pressure plate 5 to move vertically downward, pressing one end of the film bag onto the cutting table 1. The electric push rod 9 is activated, and its output shaft extends, driving the pressure plate 10 to move vertically downward and press it onto the film bag. Then, the electric telescopic column 11 on the side of the top plate 3 is activated. The output shaft of the electric telescopic column 11 moves and pushes the movable block 13 to slide on the slide rail 12. The sliding of the movable block 13 drives the electric push rod 9 and the pressure plate 10 to move away from the electric push rod 6. During the movement of the pressure plate 10, the pressed film bag is straightened, effectively eliminating wrinkles and bends generated during the conveying process. Subsequently, the electric push rod 6 is activated, and its output shaft extends, driving the horizontal plate 7 and the cutter 8 set on the bottom surface of the horizontal plate 7 to move vertically downward, cutting the straightened film bag and ensuring that the bag is flat during cutting.
[0051] By repeating the above process, the film bag can be continuously straightened and cut.
[0052] This bag-making machine's cutting device can straighten the film bag before cutting, effectively eliminating wrinkles and bends generated during the conveying process, ensuring that the bag is flat during cutting, thereby improving cutting accuracy, reducing the defect rate, and making it highly practical.
[0053] in,
[0054] Both pressure plate 5 and pressure plate 10 have rubber pads on their bottom surfaces. During the pressing process, these pads prevent pressure plate 5 and pressure plate 10 from directly contacting the film bag and causing damage, thus protecting the film bag. At the same time, the rubber material has a certain friction, which increases the friction between the pressure plate and the film bag, making the film bag more stable during the straightening process and less prone to displacement, thereby improving the stability of the film bag during the straightening process.
[0055] After the cutter 8 finishes cutting the film bag, the electric telescopic column 11 continues to drive the pressure plate 10 to move, moving the film bag to the inclined side of the cutting table. Under the influence of gravity, the film bag slides down the inclined side. The collection frame 14 set at the inclined side can receive the sliding film bag, realizing automatic feeding. There is no need for manual collection of the cut film bags, which effectively improves the cutting efficiency and makes the whole bag making and cutting process smoother.
[0056] The collection box 14 is snapped onto the side of the cutting table 1. When a certain number of film bags have been collected in the collection box 14, the staff can easily remove the collection box 14 from the side of the cutting table 1 by simply separating the snap joint. This allows for convenient and quick cutting of the film bags in the collection box 14. After cutting, the collection box 14 can be snapped back onto the side of the cutting table 1 to continue receiving the subsequent cut film bags, thus improving the convenience of cutting the collection box 14.
[0057] When the electric push rod 6 drives the horizontal plate 7 and the cutter 8 to move downward to cut the film bag, the cutter 8 is subjected to resistance from the cutting table 1. The resistance is transmitted to the spring 16 in the movable opening 15 through the movable rod 17. The spring 16 deforms and buffers the cutter 8, reducing the impact force on the cutter 8 and thus improving the service life of the cutter 8.
[0058] The size of the movable rod 17 is matched with the size of the movable opening 15, ensuring that the movable rod 17 can slide smoothly up and down within the movable opening 15. At the same time, the damping set between the two prevents the movable rod 17 from shaking during the sliding process. When the cutter 8 is cutting, the movable rod 17 can stably support the cutter 8. The cutter 8 cuts the film bag in a stable state, which can ensure that the film bag will not be displaced due to the shaking of the cutter 8 during the cutting process, thereby improving the stability of the film bag during cutting and ensuring the cutting quality.
[0059] A controller is installed on the side of the cutting table 1, which can automatically control each component of the device, thereby automatically controlling the straightening and cutting process of the film bag.
[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
