Technical Field
[0001] This utility model relates to the field of garbage bag cutting technology, and in particular to a cutting device for garbage bag production. Background Technology
[0002] In the existing garbage bag production process, the cutting device is an indispensable and important piece of equipment. However, the garbage bag cutting devices currently on the market generally have some problems. During the transportation of garbage bags, due to factors such as the inherent characteristics of the material and changes in the operating speed of the equipment, it is difficult to ensure a stable tension, resulting in phenomena such as loosening and wrinkling of the garbage bags during transportation, affecting cutting accuracy and product quality. At the same time, during long-term transportation, garbage bags are prone to deviation, and there is a lack of effective correction and control methods, which further reduces the accuracy of cutting. In addition, the collection of the tail end of the garbage bags after cutting often requires manual operation, which is not only inefficient but also easily causes the garbage bags to pile up messily, increasing the difficulty and cost of subsequent sorting. For example, CN215433934U discloses a cutting device for the production of biodegradable garbage bags, including a fixed platform and a processing platform. The processing platform is fixed to the top of the fixed platform, and support plates are welded to both ends of the top of the fixed platform. A top plate is fixed to the top of the support plates. A first cylinder is fixed to one side of the bottom end of the top plate, and a second cylinder is installed and fixed to the other side of the bottom end of the top plate. This biodegradable garbage bag production cutting device incorporates a third motor and other components. When a roll needs changing, the third motor is activated, driving the lead screw to rotate via a transmission shaft. The external sleeve is guided to one end by the rotating lead screw and the bottom of the third fixed seat embedded in the groove. At this point, the second shaft on the third fixed seat disengages from the inner wall of one end of the first shaft, allowing the roll to be removed and replaced. This makes loading and changing garbage bags faster and solves the problem of inconvenient replacement of bags requiring cutting. However, during transport, the garbage bag roll may become loose or shift, affecting cutting accuracy and reducing product quality. Furthermore, after cutting, only impurities on the garbage bag are removed. Since garbage bags are lightweight, they may become scattered during transport, making direct bundling inconvenient and requiring manual sorting, increasing labor costs. Therefore, a cutting device for garbage bag production needs to be developed to address these shortcomings. Utility Model Content

[0007] Preferably, the correction assembly includes a first gear and a second gear, a first motor, and a correction sensor. The first gear is fixedly mounted on the rotating shaft and located at the bottom end of the worktable. The first gear and the second gear mesh. The second gear is fixed on the output shaft of the first motor. The first motor drives the second gear and drives the first gear to rotate, thereby rotating the rotating disk. The correction sensor is fixed on the side of the support near the unwinding assembly. The correction sensor outputs a signal to the control system, and the control system controls the first motor to rotate.
[0008] Preferably, the limiting assembly includes a first limiting plate, a second limiting plate, a second motor, and a second electric telescopic rod. Two first limiting plates are symmetrically installed on both sides of the collection platform. The first limiting plates are horizontally positioned in the same direction as the garbage bag transport. A groove is provided on the collection platform. A T-shaped step is provided at the lower end of the first limiting plate. The T-shaped step is integrally formed with the first limiting plate and passes through the groove, slidingly connecting to it. Fixed plates are provided at both ends of the lower longitudinal direction of the collection platform. A bidirectional screw is rotatably mounted on the fixed plate.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0013] This utility model relates to a cutting device for garbage bag production. By incorporating a tension adjustment component and utilizing a tension detector to monitor the tension of the garbage bag roll in real time, the device transmits the signal to a control system. The control system then controls the movement of a first electric telescopic rod, driving the corresponding guide roller to move up and down, thereby dynamically adjusting the tension of the garbage bag roll. This effectively solves problems such as loosening and wrinkling of garbage bags during transport, ensuring the stability of garbage bag transport. A correction sensor in the correction component monitors the deviation of the garbage bag roll in real time and transmits the signal to the control system. The control system controls the rotation of a first motor, which, through the meshing of a first gear and a second gear, drives the rotating shaft to rotate, thereby rotating the rotating disk and achieving timely adjustment of the garbage bag roll deviation. This prevents the garbage bag roll from shifting during long-term transport, improves cutting accuracy, and ensures product quality. The collection component has several elastic claws on the upper end of the collection roller, which are divided into several groups and evenly distributed on the circumference of the collection roller. The third motor drives the collecting roller to rotate, causing the elastic claw at the top to automatically output the cut garbage bags onto the collecting platform. This achieves automatic collection of the tail end of the cut garbage bags, eliminating the need for manual operation and greatly improving production efficiency. The limiting components installed on the collecting platform are driven by a second motor to rotate a bidirectional lead screw, causing the first limiting plates on both sides to move closer or further apart, thus limiting the cut garbage bags laterally. A second electric telescopic rod drives the second limiting plate forward or backward, limiting the cut garbage bags longitudinally. This structure can quickly and neatly collect the cut garbage bags on the collecting platform, facilitating subsequent bundling, reducing the difficulty and time of subsequent sorting, and further improving production efficiency.

[0020] The core of this utility model is to provide a cutting device for garbage bag production. By adjusting the tension adjustment component and the correction component in the transmission component, the garbage bag roll in the transmission is adjusted in real time to improve the cutting accuracy of garbage bag production. Furthermore, the cutting garbage bags are effectively collected by the collection component, thereby reducing labor costs.
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them.

Therefore, they should not be construed as limitations on this utility model.
[0023] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the cutting device for producing garbage bags according to this utility model; Figure 2 This is a schematic diagram of the main structure of the cutting device for producing garbage bags according to this utility model; Figure 3 This is a top view of the cutting device for producing garbage bags according to this utility model; Figure 4 This is a schematic diagram of the main sectional view of the cutting device for producing garbage bags according to this utility model.
[0024] In one specific implementation, such as Figures 1-4 As shown, a cutting device for producing garbage bags includes a frame 1 with a worktable 2 at its upper end. An unwinding assembly 3, a conveying assembly 4, a cutting assembly 5, and a collecting assembly 6 are sequentially arranged on the worktable 2. The unwinding assembly 3 is rotatably mounted on the front end of the worktable 2 via a vertical plate 7. The vertical plate 7 has two pieces vertically fixed to both sides of the worktable 2, and the axis of the unwinding assembly 3 is perpendicular to the conveying direction of the garbage bag roll. The unwinding assembly 3 includes an unwinding roller rotatably connected to the vertical plate 7 via a bearing. The unwinding roller carries the garbage bag roll to be cut, and its axis is perpendicular to the conveying direction of the garbage bag. The unwinding roller has spirally distributed anti-slip patterns to prevent the garbage bag roll from slipping during the unwinding process.
[0025] The transmission component 4 is located behind the unwinding component 3. The transmission component 4 includes guide rollers 41, a tension adjustment component 42, and a deviation correction component 43. Multiple sets of guide rollers 41 are provided, each set fixed to the upper surface of the workbench 2 via a mounting frame 8 in a parallel and staggered manner. These multiple sets of guide rollers 41 together form the transmission channel for the garbage bag roll. The tension adjustment component 42 is located at the lower end of one set of guide rollers 41 and adjusts the tension of the garbage bag roll by driving the corresponding guide roller 41 up and down via a first electric telescopic rod 421, adapting to garbage bag rolls of different materials and specifications. A rotating disk 9 is fixedly mounted at the lower end of the first electric telescopic rod 421. A rotating shaft 10 is located at the center of the lower end of the rotating disk 9. The rotating shaft 10 passes through the frame 1 and is fixedly connected to the deviation correction component 43 located at the bottom of the frame 1. The deviation correction component 43 drives the rotating shaft 10 to rotate, thereby causing the rotating disk 9 to rotate, thus adjusting the deviation of the garbage bag roll. The collection component 6 includes a collection platform 61 located at the tail of the workbench 2. A limiting component 62 for limiting the cut garbage bags is installed on the collection platform 61. A collection roller 63 is provided at the front end of the limiting component 62 for conveying the cut garbage bags into the limiting component 62.
[0026] In one specific implementation, such as Figures 1-4 As shown, the tension adjustment assembly 42 also includes a support 422 and a tension detector 423. The support 422 has an overall U-shaped structure with the opening facing upwards. A set of guide rollers 41 are rotatably installed on both sides of the upper end of the support 422. The tension detector 423 is located in the middle of the bottom of the support 422. The tension detector 423 is fixedly installed on the bottom of the inner side of the support 422 by bolts. The detection end of the tension detector 423 abuts against the lower end face of the garbage bag roll. The tension detector 423 is connected to the first electric telescopic rod 421. The tension detector 423 outputs a signal to the control system, and the control system controls the movement of the first electric telescopic rod 421.
[0027] Tension detector 423 is positioned at the bottom of the garbage bag roll to monitor its tension in real time. When the tension decreases due to material properties or changes in equipment operating speed, tension detector 423 detects a signal and transmits it to the control system. Upon receiving the signal, the control system shortens the first electric telescopic rod 421, pushing the corresponding guide roller 41 downward to increase the tension of the garbage bag roll. Conversely, when the tension is too high, the control system extends the first electric telescopic rod 421, causing the guide roller 41 to move upward to decrease the tension of the garbage bag roll, thus achieving dynamic adjustment of the garbage bag tension.
[0028] In one specific implementation, such as Figures 1-4 As shown, the web guiding assembly 43 includes a first gear 431, a second gear 432, a first motor 433, and a web guiding sensor 434. The first gear 431 is fixedly mounted on the rotating shaft 10 and located at the bottom of the worktable 2. The first gear 431 and the second gear 432 mesh. The second gear 432 is fixed on the output shaft of the first motor 433. The first motor 433 drives the second gear 432 and drives the first gear 431 to rotate, thereby causing the rotating disk 9 to rotate. The web guiding sensor 434 is fixed on the side of the support 422 near the unwinding assembly 3. The web guiding sensor 434 outputs a signal to the control system, and the control system controls the first motor 433 to rotate.
[0029] The correction sensor 434 monitors the deviation of the garbage bag roll in real time. When the garbage bag deviates, the correction sensor 434 detects the signal and transmits it to the control system. The control system controls the first motor 433 to rotate based on the detection signal. The output shaft of the first motor 433 drives the second gear 432 to rotate. The second gear 432 meshes with the first gear 431, thereby driving the first gear 431 and the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 causes the rotating disk 9 to rotate, which in turn adjusts the angle of the guide roller 41, returning the garbage bag to the correct conveying position and correcting the garbage bag deviation.
[0030] In one specific implementation, such as Figures 1-4As shown, the limiting assembly 62 includes a first limiting plate 621, a second limiting plate 622, a second motor 623, and a second electric telescopic rod 624. Two first limiting plates 621 are symmetrically installed on both sides of the collection platform 61. The first limiting plates 621 are horizontally positioned in the same direction as the garbage bag transport, ensuring effective limiting of the garbage bag. The collection platform 61 has a sliding groove 625. The lower end of the first limiting plate 621 has a T-shaped step, which is integrally formed with the first limiting plate 621 and passes through and slidably connects to the sliding groove 625, ensuring that the first limiting plate 621 can slide smoothly within the sliding groove 625. Fixed plates 626 are provided at both ends of the lower longitudinal direction of the collection platform 61. The fixed plates 626 are fixed to the lower end face of the collection platform 61 by welding or bolting. A bidirectional lead screw 627 is rotatably mounted on the fixed plate 626. The bidirectional lead screw 627 passes through the T-shaped step and is threadedly connected to the T-shaped step. The threads at both ends of the bidirectional lead screw 627 are in opposite directions. When the bidirectional lead screw 627 rotates, it can cause the T-shaped steps on both sides to move simultaneously towards the middle or to the sides. One end of the bidirectional lead screw 627 extends into the fixed plate 626 and is fixedly mounted on the output shaft of the second motor 623. The second motor 623 is horizontally mounted on the outside of the fixed plate 626 and drives the bidirectional lead screw 627 to move the first limiting plates 621 on both sides closer or further apart. The second motor 623 drives the bidirectional lead screw 627 to rotate, causing the first limiting plates 621 on both sides to move closer or further apart, thereby accommodating the collection of garbage bags of different sizes. The second limiting plate 622 is located at the rear of the collection platform 61. The second limiting plate 622 is perpendicular to the first limiting plate 621, and its back is fixedly mounted on the second electric telescopic rod 624. The second electric telescopic rod 624 drives the second limiting plate 622 to move forward or backward. This further limits and organizes the cut garbage bags in both horizontal and vertical directions, facilitating subsequent collection. Rubber cushioning pads are attached to the front faces of the first limiting plate 621 and the second limiting plate 622. When the garbage bag comes into contact with the first limiting plate 621 and the second limiting plate 622, the rubber cushioning pads provide cushioning to prevent damage to the garbage bag.
[0031] In one specific implementation, such as Figures 1-4 As shown, the cutting component 5 is located between the collecting component 6 and the conveying component 4, and includes a cutting bracket 51 fixed on the worktable 2. A cutting blade 52 and a cutting cylinder 53 for driving the cutting blade 52 to move up and down are installed on the cutting bracket 51. A through groove for accommodating the cutting blade 52 is provided on the worktable 2 at the location corresponding to the cutting blade 52.
[0032] In one specific implementation, such as Figures 1-4As shown, the upper end of the collecting roller 63 is equipped with several elastic claws 631, which are divided into several groups and evenly distributed on the circumference of the collecting roller 63. Each group of elastic claws 631 contains 3-5 claws to ensure stable gripping and conveying of garbage bags. The two ends of the collecting roller 63 are fixedly installed at the front end of the cutting bracket 51. One end of the collecting roller 63 extends out of the cutting bracket 51 and is fixedly installed with a third motor 64. The third motor 64 drives the collecting roller 63 to rotate, causing the upper elastic claws 631 to output the cut garbage bags onto the collecting platform 61. The third motor 64 drives the collecting roller 63 to rotate, causing the upper elastic claws 631 to grip the cut garbage bags from the cutting position and convey them to the collecting platform 61 during the rotation, realizing the automatic collection of cut garbage bags. The surface of the collecting roller 63 is also equipped with an anti-static coating to prevent garbage bags from being attracted to the collecting roller 63 due to static electricity.
[0033] In one specific implementation, such as Figures 1-4 As shown, the elastic claw 631 is made of elastic silicone rubber material and has an arc shape, which enables it to better grasp and transport garbage bags.
[0034] The operation of this utility model's cutting device for garbage bag production is as follows: Garbage bag rolls are mounted on the unwinding assembly 3. The garbage bags are then drawn out from the unwinding assembly 3 and enter the conveying assembly 4. The garbage bags sequentially pass through a conveying channel composed of multiple sets of guide rollers 41. During the conveying process, a tension detector 423 monitors the tension of the garbage bag roll in real time. When the tension does not meet the set value, the tension detector 423 transmits a signal to the control system. The control system controls the first electric telescopic rod 421 to move, driving the corresponding guide rollers 41 up and down to adjust the tension of the garbage bag roll and ensure smooth conveying of the garbage bags. Simultaneously, a deviation correction sensor 434 monitors the deviation of the garbage bag roll in real time. If the garbage bag deviates, the deviation correction sensor 434 transmits a signal to the control system. The control system controls the first motor 433 to rotate, driving the rotating shaft 10 to rotate through the meshing transmission of the first gear 431 and the second gear 432, thereby causing the rotating disk 9 to rotate, adjusting the angle of the guide rollers 41, and correcting the deviation of the garbage bag. When the garbage bag is conveyed to the cutting assembly 5, the cutting cylinder 53 drives the cutting blade 52 to move downwards, cutting the garbage bag through the through groove on the worktable 2. The cut garbage bag is grabbed by the elastic claw 631 on the collecting roller 63, and the third motor 64 drives the collecting roller 63 to rotate, conveying the garbage bag to the collecting platform 61. After the garbage bag arrives at the collecting platform 61, the second motor 623 drives the bidirectional lead screw 627 to rotate, causing the first limiting plates 621 on both sides to move closer together, thus limiting the garbage bag laterally; the second electric telescopic rod 624 drives the second limiting plate 622 to move forward, thus limiting the garbage bag longitudinally, and neatly collecting the garbage bag on the collecting platform 61.
