Description

Technical Field

[0001] This application relates to the field of textile yarn technology, specifically to a pre-compressed yarn automatic packaging machine. Background Technology

[0002] Pre-compression automatic yarn packaging machine is a specialized piece of equipment used in the finishing process of the textile industry to automatically package finished yarns (mainly cone yarns and skeins) with high density and regularity. Its core feature is the adoption of a two-stage process of "pre-compression-final compression and bundling" to solve the problems of loose, large volume and irregular shape of yarn bales caused by traditional packaging methods. It is a key piece of equipment for realizing the automation, standardization and efficient logistics of yarn packaging.

[0003] Currently, textile yarn is generally compressed by pressing and tightening during pre-compression. However, pressing and tightening still leaves some loose space, which takes up space during packaging and transportation, resulting in poor pre-compression efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a pre-compressed yarn automatic packaging machine, which solves the problem mentioned in the background technology that the pre-compression of textile yarn packages is generally carried out by compression and pressing, but there is still some loose space when pressing and compressing, which occupies space during packaging and transportation, resulting in poor pre-compression efficiency.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This application provides a pre-compressed yarn automatic packaging machine, including a worktable. The worktable has a conveying mechanism for transporting yarn packages inside. A packaging bag is placed above the worktable. An expansion mechanism for expanding the opening of the packaging bag is located at the upper end of the worktable. A heat-sealing mechanism for heat-sealing the yarn packages is also located at the upper end of the worktable. A pre-compression mechanism for pre-compressing the yarn packages is also located at the upper end of the worktable. The pre-compression mechanism includes a compression cylinder fixedly installed at the upper end of the worktable. A compression plate is fixedly installed at the telescopic end of the compression cylinder. The compression plate corresponds to the opening of the packaging bag. An air extraction pipe is sewn onto one outer wall of the packaging bag. A cap is spirally installed on the outer wall of the air extraction pipe. The air extraction pipe and cap are made of rubber. The packaging bag is made of an airtight plastic film.

[0007] By adopting the above technical solution, a compression plate driven by a compression cylinder is used to pre-compress the textile yarn on the conveying mechanism, tightly pressing the yarn into the packaging bag. This effectively removes the loose space between the yarns, significantly reducing the packaging volume. The vacuum pipe on the packaging bag can be connected to an external vacuum device for further vacuuming. With the pipe cap sealing, secondary compression is achieved, creating a vacuum state inside the packaging bag, further reducing volume and footprint. This structure is easy to operate, has high compression efficiency, and effectively solves the problems of large loose space and excessive transportation space occupied by traditional compression methods, significantly improving yarn packaging density and logistics efficiency.

[0008] Optionally, the conveying mechanism includes two conveying rollers rotatably mounted on the inner wall of the workbench, with a conveyor belt tensioned around the outer walls of the two conveying rollers, and a stepper motor fixedly mounted on the inner wall of the workbench, with the output shaft of the stepper motor fixedly mounted to one of the conveying rollers.

[0009] By adopting the above technical solution, the workbench can provide rotational support for the conveyor roller, and the stepper motor can drive the conveyor roller to rotate. Thus, the conveyor roller and the conveyor belt can cooperate to convey the textile yarn. An external transport mechanism can be set on one side of the conveyor belt to transport the textile yarn onto the conveyor belt.

[0010] Optionally, the expansion mechanism includes a mounting bracket fixedly installed on the upper end of the workbench. Expansion cylinders are fixedly installed on the opposite outer walls of the mounting bracket. Expansion grippers are fixedly installed on the telescopic ends of the two sets of expansion cylinders. The two expansion grippers are located on the inner walls of both sides of the packaging bag.

[0011] By adopting the above technical solution, the workbench can fix the mounting bracket, which in turn can fix the expansion cylinder. The expansion cylinder can drive the expansion gripper to extend and retract, thereby facilitating the expansion gripper to expand and support the inner wall of the packaging bag, and making it easier for the yarn to enter the textile package.

[0012] Optionally, the heat sealing mechanism includes a U-shaped frame fixedly installed at the lower end of the workbench. A heat sealing cylinder is fixedly installed at the upper end of the mounting bracket and the outer wall of the U-shaped frame, respectively. A connecting plate is fixedly installed at the telescopic end of the heat sealing cylinder located below the U-shaped frame. A heat sealing knife is fixedly installed at the telescopic end of the heat sealing cylinder located above the mounting bracket and at the upper end of the connecting plate, respectively. The heat sealing knife located below the workbench passes through the workbench.

[0013] By adopting the above technical solution, the workbench can fix the U-shaped frame, and the U-shaped frame and mounting bracket can fix the heat sealing cylinder. Then, the upper heat sealing cylinder can directly drive the corresponding heat sealing knife to move vertically, while the lower heat sealing cylinder can drive the connecting plate and the corresponding heat sealing knife to move vertically, so that the two heat sealing knives can heat seal the packaging bag. The heat sealing knife is existing technology and is not described in detail here. The heat sealing knife is a hollow knife body with a heating mechanism, such as a heating tube or heating plate, and a temperature sensor is installed inside.

[0014] Optionally, two sets of limiting plates of different lengths are fixedly installed on the upper end of the worktable located on both sides of the conveying mechanism. The two sets of limiting plates are set according to the reserved space of the worktable. A baffle is fixedly installed on the upper end of the connecting plate, and the baffle is located on one side of the conveyor belt.

[0015] By adopting the above technical solution, the workbench can fix the limiting plate, which can limit the movement of the textile bobbins during the compression process and also limit the movement of the textile bobbins conveyed on the conveying mechanism. When the heat sealing mechanism is running, the textile bobbins on the conveying mechanism have been compressed into the packing strap, and the conveying mechanism is in an empty state. The connecting plate will drive the heat sealing knife to move vertically, and the baffle on the connecting plate will also move accordingly. Then the baffle can limit the movement of the conveying mechanism, which facilitates the formation of a row of textile bobbins on the conveying mechanism. After the heat sealing mechanism is completed, the baffle moves downward, the conveying mechanism is completed, and then the pre-compression mechanism starts to run.

[0016] Optionally, a controller is fixedly installed on the upper end of the worktable, and the controller is electrically connected to the stepper motor, the expansion cylinder, the heat sealing cylinder, the heat sealing knife, and the compression cylinder.

[0017] By adopting the above technical solution, the workbench can fix the controller, and the controller can facilitate the operation of the stepper motor, expansion cylinder, heat sealing cylinder, heat sealing knife and compression cylinder by the operator. In addition, the controller is generally equipped with a PLC core board to facilitate its intelligent operation.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] This technical solution pre-compresses the textile yarn on the conveying mechanism by setting a compression cylinder to drive a compression plate, tightly pressing the yarn into the packaging bag, effectively eliminating the loose space between the yarns, and significantly reducing the packaging volume. The air extraction pipe on the packaging bag can be connected to an external vacuum device for further vacuuming. With the help of the pipe cap for sealing, secondary compression is achieved, creating a vacuum state inside the packaging bag, further reducing the volume and footprint. This structure is easy to operate, has high compression efficiency, and effectively solves the problems of large loose space and large transportation space occupation in traditional compression methods, significantly improving yarn packaging density and logistics efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-4This application provides a technical solution: a pre-compressed yarn automatic packaging machine, including a workbench 1, a conveying mechanism 2 for conveying textile yarns inside the workbench 1, a packaging bag 6 placed above the workbench 1, an expansion mechanism 3 for expanding the opening of the packaging bag 6 at the upper end of the workbench 1, a heat sealing mechanism 4 for heat sealing the textile yarns at the upper end of the workbench 1, and a pre-compression mechanism 5 for pre-compressing the textile yarns at the upper end of the workbench 1. The pre-compression mechanism 5 includes a compression cylinder 501 fixedly installed at the upper end of the workbench 1, a compression plate 502 fixedly installed at the telescopic end of the compression cylinder 501, the compression plate 502 corresponding to the opening of the packaging bag 6, an air extraction pipe 7 sewn onto one side of the outer wall of the packaging bag 6, a pipe cap 8 spirally installed on the outer wall of the air extraction pipe 7, the air extraction pipe 7 and the pipe cap 8 being made of rubber, and the packaging bag 6 being made of an airtight plastic film.

[0028] In the technical solution of this application, a compression cylinder 501 drives a compression plate 502 to pre-compress the textile yarn on the conveying mechanism 2, tightly pressing the yarn into the packaging bag 6, effectively expelling the loose space between the yarns, significantly reducing the packaging volume. The vacuum pipe 7 on the packaging bag 6 can be connected to an external vacuum device for further vacuuming, and with the sealing of the pipe cap 8, a secondary compression is achieved, creating a vacuum state inside the packaging bag 6, further reducing the volume and footprint. This structure is easy to operate, has high compression efficiency, and effectively solves the problems of large loose space and large transportation space occupation in traditional compression methods, significantly improving yarn packaging density and logistics efficiency.

[0029] In the technical solution of this application, such as Figure 1 , Figure 3 and Figure 4 As shown, the expansion mechanism 3 includes a mounting bracket 301 fixedly installed on the upper end of the workbench 1. Expansion cylinders 302 are fixedly installed on the opposite outer walls of the mounting bracket 301. Expansion grippers 303 are fixedly installed on the telescopic ends of the two sets of expansion cylinders 302. The two expansion grippers 303 are located on the inner walls of both sides of the packing bag 6. The workbench 1 can fix the mounting bracket 301, and the mounting bracket 301 can fix the expansion cylinders 302. The expansion cylinders 302 can drive the expansion grippers 303 to extend and retract, thereby facilitating the expansion grippers 303 to expand and support the inner wall of the packing bag 6, and facilitating the entry of the textile yarn.

[0030] In the technical solution of this application, such as Figure 1 and Figure 2As shown, the heat sealing mechanism 4 includes a U-shaped frame 402 fixedly installed at the lower end of the workbench 1. A heat sealing cylinder 401 is fixedly installed at the upper end of the mounting bracket 301 and the outer wall of the U-shaped frame 402, respectively. A connecting plate 403 is fixedly installed at the telescopic end of the heat sealing cylinder 401 located below the U-shaped frame 402. A heat sealing blade 404 is fixedly installed at the telescopic end of the heat sealing cylinder 401 located above the mounting bracket 301 and at the upper end of the connecting plate 403, respectively. The heat sealing blade 404 located below the workbench 1 passes through the workbench 1, and the workbench 1 can fix the U-shaped frame 402. The U-shaped frame 402 and the mounting bracket 301 can fix the heat sealing cylinder 401. Then, the upper heat sealing cylinder 401 can directly drive the corresponding heat sealing knife 404 to move vertically, while the lower heat sealing cylinder 401 can drive the connecting plate 403 and the corresponding heat sealing knife 404 to move vertically, so that the two heat sealing knives 404 can heat seal the packaging bag 6. The heat sealing knife 404 is existing technology and is not described in detail here. The heat sealing knife 404 is a hollow knife body with a heating mechanism, such as a heating tube or a heating plate, and a temperature sensor inside.

[0031] In the technical solution of this application, such as Figure 3 and Figure 4 As shown, the conveying mechanism 2 includes two conveying rollers 201 rotatably mounted on the inner wall of the workbench 1. A conveyor belt 202 is tensioned and sleeved on the outer wall of the two conveying rollers 201. A stepper motor 203 is fixedly mounted on the inner wall of the workbench 1. The output shaft of the stepper motor 203 is fixedly mounted to one of the conveying rollers 201. The workbench 1 can provide rotational support for the conveying rollers 201, and the stepper motor 203 can drive the conveying rollers 201 to rotate. Thus, the conveying rollers 201 and the conveyor belt 202 cooperate to convey the textile yarn. An external transport mechanism 2 can be set on one side of the conveyor belt 202 to transport the textile yarn onto the conveyor belt 202.

[0032] In the technical solution of this application, such as Figures 1-4As shown, two sets of limiting plates 10 of different lengths are fixedly installed on the upper end of the worktables 1 located on both sides of the conveyor mechanism 2. The two sets of limiting plates 10 are set according to the reserved space of the worktables 1. A baffle 9 is fixedly installed on the upper end of the connecting plate 403. The baffle 9 is located on one side of the conveyor belt 202. The worktables 1 can fix the limiting plate 10. The limiting plate 10 can limit the textile yarn in the compression process and can also limit the textile yarn conveyed on the conveyor mechanism 2. When the heat sealing mechanism 4 is running, the textile yarn on the conveyor mechanism 2 has been compressed into the packing belt, and the conveyor mechanism 2 is in an empty state. The connecting plate 403 will drive the heat sealing knife 404 to move vertically, and the baffle 9 on the connecting plate 403 will also move accordingly. Then the baffle 9 can limit the conveyor belt 202. The conveying mechanism 2 serves as a limit switch, facilitating the formation of a row of yarn packages on the conveying mechanism 2. After the heat sealing mechanism 4 completes the heat sealing, the baffle 9 moves downward, completing the conveying process of the conveying mechanism 2. Subsequently, the pre-compression mechanism 5 begins operation. A controller 11 is fixedly installed on the upper end of the workbench 1. The controller 11 is electrically connected to the stepper motor 203, the expansion cylinder 302, the heat sealing cylinder 401, the heat sealing knife 404, and the compression cylinder 501. The workbench 1 can fix the controller 11 in place. The controller 11 allows operators to easily control the stepper motor 203, the expansion cylinder 302, the heat sealing cylinder 401, the heat sealing knife 404, and the compression cylinder 501. The controller 11 typically has a PLC core board inside for intelligent operation.

[0033] In use, the worker first places the plastic film packaging bag 6 on the workbench 1. At this time, the two sets of expansion cylinders 302 in the expansion mechanism 3 are activated, driving the expansion gripper 303 to move outward, opening the packaging bag 6 and maintaining it in an expanded state. At the same time, the stepper motor 203 in the conveying mechanism 2 drives the conveyor roller 201 to rotate, so that the conveyor belt 202 sleeved on the conveyor roller 201 conveys the textile yarn to the pre-compression station. During the conveying process, the limiting plates 10 set on both sides of the upper end of the workbench 1 limit the textile yarn to ensure that the yarn is arranged neatly. When the conveyor belt 202 conveys a row of textile yarn to the position corresponding to the opening of the packaging bag 6, At this time, the compression cylinder 501 in the pre-compression mechanism 5 starts, driving the compression plate 502 to move and apply pressure to the textile yarn on the conveyor belt 202, pressing the yarn tightly into the packaging bag 6. The loose space between the yarns is discharged through mechanical compression, completing the pre-compression. After the pre-compression is completed, the compression cylinder 501 resets, and the conveying mechanism 2 continues to run, conveying the next batch of yarn to the pre-compression station. Then, the heat sealing mechanism 4 starts to work. The heat sealing cylinder 401 on the U-shaped frame 402 and the mounting bracket 301 starts simultaneously, driving the upper and lower heat sealing blades 404 to move towards each other. The heating element inside the heat sealing blade 404 is energized and heats up. When the two heat sealing blades 404 contact the packaging bag, the heat sealing mechanism 4 starts to work. When bag 6 is opened, the opening is heat-sealed by heat pressing, achieving a seal. During the heat sealing process, connecting plate 403 moves baffle 9 upward, limiting the next batch of yarn bobbins on conveyor mechanism 2 to ensure neat arrangement. After heat sealing, heat sealing cylinder 401 resets, and baffle 9 also resets. At this time, the operator can connect an external vacuum device to the vacuum pipe 7 on bag 6 to perform vacuuming inside bag 6, further removing residual air and creating a vacuum state inside bag 6, significantly reducing packaging volume. After vacuuming, the rubber cap 8 is screwed onto the vacuum pipe 7 to achieve a secondary seal. The controller 11 uses an internally installed PLC chip to programmatically control the entire workflow, coordinating the sequential actions of the stepper motor 203, expansion cylinder 302, heat sealing cylinder 401, heat sealing knife 404, and compression cylinder 501 to achieve automated operation. Through the dual compression process of pre-compression and vacuuming, the problem of large fluff space and large transportation space occupation in the traditional pressing compression method is effectively solved, significantly improving the yarn packaging density and logistics efficiency. At the same time, the entire process is highly automated, easy to operate, and has high compression efficiency. Furthermore, the heat sealing knife 404 is located on one side of the expansion gripper 303, and the expansion gripper 303 will not affect the heat sealing of the heat sealing knife 404.
