Abstract
Description
Technical Field
[0001] This invention relates to the field of pillow processing and packaging technology, specifically to a packaging device for pillow processing. Background Technology
[0002] In the large-scale production process of home textile products, after pillows have completed filling and shaping, they typically require sealing with plastic film for outer packaging. This is to isolate dust and moisture, reduce volume during transportation and storage, and improve product appearance and distribution safety. With the popularization of intelligent manufacturing technology in the home textile industry, integrated automatic compression, degassing, and heat-sealing packaging equipment has gradually replaced traditional manual packaging, becoming the mainstream equipment in the later stages of pillow processing.
[0003] Most conventional pillow packaging equipment on the market currently uses a conveyor belt conveyor, cylinder-driven pressure plate compression, and direct heat sealing by heating components. After the bagged pillow is conveyed to the sealing station, the heating strip is pressed down by the cylinder, causing the plastic film to melt and complete the sealing process. This type of equipment has a relatively simple structural design, mainly relying on heating temperature and downward pressure to achieve sealing. Before sealing, it lacks a structure for preparing, smoothing, and adaptively fitting the bag opening. The contact between the heat sealing components and the packaging bag is mostly rigid, and it cannot be adaptively adjusted according to the actual condition of the bag opening.
[0004] However, traditional pillow packaging equipment cannot pre-smooth the opening of the packaging bag during the sealing process, resulting in wrinkles, curling, and unevenness at the opening. Direct heat sealing will cause the sealing area to be inadequate, leading to cracks in the seal and air leakage from gaps, which seriously reduces the sealing performance of the pillow packaging and the finished product qualification rate. Summary of the Invention

[0012] Preferably, the material feeding assembly further includes a base, which is disposed below the conveyor frame. A third spring is fixedly connected to the top of the base, and a tray is fixedly connected to the other end of the third spring. A weighing sensor is fixedly connected to the top of the base, and a telescopic guide rod is fixedly connected to the top of the base.

[0016] This invention provides a packaging device for pillow processing. It has the following beneficial effects: 1. This invention drives the mounting plate with a first cylinder, and through the rotating plate and the first connecting plate, drives the mounting plates on both sides to move synchronously toward the packaging bag, so that the smoothing roller contacts the bag opening first. Under the elastic action of the first spring, it adaptively fits the bag surface and deflects the roller to press, thereby achieving the effect of automatically smoothing the bag opening wrinkles. This solves the problem of poor heat sealing and air leakage caused by bag opening wrinkles. The above structure improves the sealing performance and yield of pillow packaging.
[0017] 2. This invention uses a motor-driven gear to drive the racks on both sides and the connecting plate to slide synchronously towards each other, so that the push plate and the inclined plate approach the pillow, thereby achieving the effect of automatic correction and centering. This solves the problem of offset and crooked bags in existing pillow packaging. At the same time, through the inclined surface pressing cooperation between the inclined plate and the pressure plate, the push plate is driven to rotate and avoid and lock into the groove of the pressure plate, avoiding mechanical interference and ensuring smooth compression and exhaust. The above structure improves the positioning accuracy and compression and exhaust efficiency of pillow packaging.
[0018] 3. This invention uses photoelectric sensors to detect pillows entering the conveyor in real time, sends signals to the first controller, and completes cumulative counting. At the same time, the tray, supported by the third spring and telescopic guide rod, gradually sinks as the cumulative weight of the pillows increases. The weighing sensor detects this, and the first controller controls the second cylinder to move, causing the paddle to swing and switch the material dropping channel. This achieves automatic counting, full-box detection, and automatic box changing, solving the problems of low efficiency and overflow of existing manual box changing. The above structure improves the automation level and production continuity of pillow packaging. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.
[0022] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a packaging device for pillow processing, including a first conveyor belt 1, a base 2 on one side of the first conveyor belt 1, a frame 3 fixedly connected above the base 2, a smoothing component 4 below the frame 3 for smoothing the sealing area of the packaging tape, an anti-deviation component 5 inside the base 2 for guiding the pillow and preventing deviation, a material dropping component 6 on one side of the base 2 for conveying the packaged pillow, a second conveyor belt 7 rotatably connected inside the base 2, and a second controller 10 fixedly connected to the outside of the base 2.
[0023] Specifically, the first conveyor belt 1 is used to transport the bagged pillows to the next processing station and is directly connected to the second conveyor belt 7. A base 2 is provided on one side of the first conveyor belt 1. The base 2 serves to support the frame 3, the anti-deviation component 5, and the second conveyor belt 7. The frame 3 is fixedly connected above the base 2. The frame 3 is welded from channel steel to support the smoothing component 4, the third cylinder 8, and the pressure plate 9. The smoothing component 4 is provided below the frame 3. The smoothing component 4 is used to smooth the sealing area of the packaging tape and cooperate with the subsequent heating strip 43 for heat sealing to ensure that the bag opening is flat and wrinkle-free, thereby improving the heat sealing performance. The anti-deviation component 5 is provided inside the base 2 to guide the pillows and prevent deviation, thereby achieving accurate positioning and preventing misaligned bags. A material feeding assembly 6 is provided on one side of the base 2. The material feeding assembly 6 is used to transport, count and sort the packaged pillows. With the help of photoelectric sensor 68 and weighing sensor 612, the material feeding and box changing are automated, which can improve the packing efficiency and reduce manual intervention. A second conveyor belt 7 is rotatably connected inside the base 2. The second conveyor belt 7 is used to receive the pillows transported by the first conveyor belt 1 and transport them to the smoothing, compression and sealing station. A second controller 10 is fixedly connected to the outside of the base 2. The second controller 10 is used to control the coordinated action of the anti-deviation assembly 5, the third cylinder 8 and the second conveyor belt 7 to realize the automated connection of each process.
[0024] Please see the appendix Figure 2 - Appendix Figure 4 In a preferred embodiment of the present invention, the smoothing component 4 includes a first cylinder 41, which is fixedly connected to the top of the frame 3. An extension plate 44 is fixedly connected to the outside of the frame 3. A rotating plate 45 is rotatably connected to the outside of the extension plate 44. Two first connecting plates 46 are rotatably connected to the outside of the rotating plate 45. Mounting plates 42 are rotatably connected to the outside of each of the two first connecting plates 46. Heating strips 43 are fixedly connected inside each of the two mounting plates 42. One mounting plate 42 is fixedly connected to the output end of the first cylinder 41, and the other mounting plate 42 is slidably connected to the outside of the base 2. Second connecting plates 47 are rotatably connected to the outside of each of the two mounting plates 42. A smoothing roller 48 is rotatably connected between the second connecting plates 47. The smoothing component 4 also includes a first spring 49, one end of which is fixedly connected to the outside of the second connecting plate 47, and the other end of which is fixedly connected to the outside of the mounting plate 42. The height of the smoothing roller 48 is higher than the height of the heating strip 43, and the second connecting plate 47 and the smoothing roller 48 are inclined.
[0025] Specifically, the first cylinder 41 drives one side mounting plate 42 to move downwards, and through the rotating plate 45 and the first connecting plate 46, it drives the two mounting plates 42 to move synchronously toward the packaging bag of the bagged pillow. The rotating plate 45 is rotatably connected to the extension plate 44 through a pin, and the two ends of the first connecting plate 46 are rotatably connected to the rotating plate 45 and the mounting plate 42 through pins respectively. The rotating plate 45 and the first connecting plate 46 work together to achieve the effect of driving the two mounting plates 42 to move synchronously and accurately close to the packaging bag, ensuring that the heating strips 43 on both sides can contact the bag opening at the same time. When the smoothing roller 48 between the second connecting plates 47 contacts the bag opening, it adaptively conforms to the bag surface under the elastic action of the first spring 49. The second connecting plate 47 is rotatably connected to the mounting plate 42 via a pin. The smoothing roller 48 is made of rubber and is used to conform to the bag opening and roll to smooth out wrinkles. It is rotatably connected to the second connecting plate 47 via a bearing. The first spring 49 is a cylindrical helical spring, which provides a continuous elastic preload to the smoothing roller 48. Together with the smoothing roller 48, it performs a conforming and rolling motion, achieving the effect of adaptively conforming to bag surfaces of different thicknesses and smoothing out wrinkles. At the same time, the squeezing action causes the second connecting plate 47 to drive the smoothing roller 48 to deflect. The first spring 49 is stretched as it deflects. The rolling and rolling action of the smoothing roller 48 smooths out the wrinkles at the bag opening, preventing wrinkles from causing poor heat sealing and ensuring that the subsequent heat sealing process can proceed smoothly.
[0026] Subsequently, the mounting plate 42 continues to press down, causing the heating strip 43 to contact the bag opening. The heating strip 43 is made of stainless steel and is used to generate high temperature to fuse the plastic film. After sealing, the first cylinder 41 resets, driving the mounting plate 42 and the smoothing roller 48 to lift synchronously. The first spring 49 elastically rebounds, causing the second connecting plate 47 to drive the smoothing roller 48 back to its initial position, ready for the next operation. This achieves an automated operation effect of smoothing first, then heat sealing, and automatic reset, ensuring that each seal is flat and tight, greatly improving the sealing quality and operational efficiency of pillow packaging.
[0027] Please see the appendix Figure 2 and attached Figure 5 In a preferred embodiment of the present invention, the anti-deviation component 5 includes a connecting plate 51, which is slidably connected to the inside of the base 2. A motor 54 is fixedly connected inside the base 2, and a gear 55 is fixedly connected to the output end of the motor 54. A rack 56 is fixedly connected to the bottom of the connecting plate 51, and the rack 56 meshes with the gear 55. A push plate 57 is rotatably connected inside the connecting plate 51, and an inclined plate 58 is fixedly connected to the outside of the push plate 57. A second spring 59 is fixedly connected inside the push plate 57, and the other end of the second spring 59 is fixedly connected to the inside of the connecting plate 51. The anti-deviation component 5 also includes a limiting rod 52, which is fixedly connected to the inside of the base 2. A slider 53 is slidably connected to the outer periphery of the limiting rod 52, and the slider 53 is fixedly connected to the bottom of the connecting plate 51.
[0028] A third cylinder 8 is fixedly connected to the top of the frame 3. A pressure plate 9 is fixedly connected to the output end of the third cylinder 8. A groove matching the connecting plate 51 is opened inside the pressure plate 9. An inclined surface is provided on the top of the inclined plate 58, and the inclined surface faces the middle of the base 2.
[0029] Specifically, after the pillow enters the second conveyor belt 7 via the first conveyor belt 1, the second controller 10 starts the motor 54. The second controller 10 is used to coordinate the timing of the anti-deviation component 5, the third cylinder 8, and the second conveyor belt 7. The motor 54 drives the gear 55 to rotate. The gear 55 is used to transmit power and is fixedly connected to the output shaft of the motor 54 via a key. The two racks 56 meshing with the gear 55 move synchronously towards each other. The racks 56 drive the connecting plate 51 to move linearly. The racks 56 and the gear 55 work together to achieve the effect of driving the two connecting plates 51 to move synchronously towards each other and accurately centering them. The racks 56 drive the two connecting plates 51 to slide towards the center along the limit rod 52 and the slider 53. The limit rod 52 is used to limit the movement trajectory of the connecting plate 51 to prevent it from deviating. The slider 53 is used to reduce the friction between the connecting plate 51 and the limit rod 52 and slides with the limit rod 52. The limit rod 52 and the slider 53 work together to guide the connecting plate 51 to slide smoothly and improve the centering accuracy.
[0030] The connecting plates 51 on both sides drive the push plate 57 and the inclined plate 58 towards the pillow. The connecting plate 51 is used to support the push plate 57, inclined plate 58 and other components. The push plate 57 is used to push the pillow to correct its deviation. It is rotatably connected to the connecting plate 51 through a pin. The top of the inclined plate 58 has an inclined surface, which is used to cooperate with the pressure plate 9 to avoid interference. The push plate 57 and the inclined plate 58 cooperate to achieve the effect of pushing the pillow and avoiding interference with the pressure plate 9. Finally, the pillow is automatically corrected and centered to avoid packaging deviation or crooked bags. This lays the foundation for subsequent compression, degassing and sealing processes. After the pillow is centered, the third cylinder 8 is used to press the second... The controller 10 drives the pressure plate 9 to move downwards. The third cylinder 8 provides sufficient downward pressure. Its cylinder body is fixedly installed on the top of the frame 3, and the piston rod is fixedly connected to the pressure plate 9. It can drive the pressure plate 9 to move up and down linearly. A soft silicone pad is pasted on the lower surface of the pressure plate 9 for mechanically compressing the bagged pillow. The pressure plate 9 has a groove inside that matches the connecting plate 51 to avoid interference with the connecting plate 51. When the pressure plate 9 moves downwards, it mechanically compresses the bagged pillow, expelling most of the air inside the bag and flattening the pillow to a set thickness, which is convenient for subsequent packaging, sealing, storage and transportation. When the third cylinder 8 drives the pressure plate 9 to press down, the pressure plate 9 contacts the inclined surface at the top of the inclined plate 58, squeezing the inclined plate 58 to make the push plate 57 rotate around the pin shaft and stretch the second spring 59. The second spring 59 is a cylindrical helical spring, which provides the reset power for the push plate 57. One end of the spring is connected to the push plate 57 through a hook, and the other end is fixedly connected to the inside of the connecting plate 51 through a hook, so that the push plate 57 is flush with the connecting plate 51. At this point, the pressure plate 9 presses down further, causing the internal groove to engage with the connecting plate 51, preventing mechanical interference between the push plate 57 and the pressure plate 9. This ensures smooth compression and exhaust, allowing air to be fully expelled from the bag and improving the neatness of the pillow packaging. This achieves automatic alignment, stable compression and exhaust, and no mechanical interference, improving the processing precision and operational efficiency of the pillow packaging.
[0031] Please see the appendix Figure 6 - Appendix Figure 8In a preferred embodiment of the present invention, the material feeding assembly 6 includes a conveyor frame 61, which is fixedly connected to one side of the base 2. A rotating rod 62 is rotatably connected inside the conveyor frame 61, and a lever plate 63 is fixedly connected to the outer periphery of the rotating rod 62. A second cylinder 64 is fixedly connected to the bottom of the conveyor frame 61, and a connector 65 is fixedly connected to the output end of the second cylinder 64. One end of the rotating rod 62 passes through the conveyor frame 61 and is fixedly connected to a push plate 66. The connector 65 is slidably connected inside the push plate 66, and a guide is fixedly connected to the outer side of the conveyor frame 61. The inner side of the conveyor frame 61 is fixedly connected to the plate 67 and the photoelectric sensor 68. The unloading assembly 6 also includes a base 69, which is located below the conveyor frame 61. A third spring 610 is fixedly connected above the base 69, and a tray 611 is fixedly connected to the other end of the third spring 610. A weighing sensor 612 is fixedly connected above the base 69, and a telescopic guide rod 613 is fixedly connected above the base 69. One end of the telescopic guide rod 613 is fixedly connected to the bottom of the tray 611. A first controller 614 is fixedly connected to the outer side of the conveyor frame 61.
[0032] Specifically, the packaged pillows enter the conveyor frame 61 via the second conveyor belt 7. The conveyor frame 61 has a Y-shaped flow guide structure, which is used to divert and guide the packaged pillows. When the photoelectric sensor 68 detects the pillow passing by, it sends a signal to the first controller 614 to accumulate counts. Then, the pillow slides down the conveyor frame 61 and the guide plate 67 onto the pre-placed packaging box on the tray 611. The guide plate 67 is used to guide the pillow to slide down and avoid the packaging bag being scratched or the posture being skewed. The tray 611 gradually sinks as the weight of the packaging box increases under the support of the third spring 610 and the telescopic guide rod 613. The third spring 610 is a cylindrical helical compression spring, which is used to elastically support the tray 611 to achieve the effect of gradually sinking with the weight. The telescopic guide rod 613 is used to limit the up and down movement trajectory of the tray 611 to prevent swaying and deviation. The third spring 610 and the telescopic guide rod 613 work together to achieve the effect of stable support and uniform sinking. When the third spring 610 is compressed to the bottom of the tray 611 and contacts the weighing sensor 612, the weighing sensor 612 detects the weight of the packaging box on the tray 611. The weighing sensor 612 is used to collect the total weight of the packaging box in real time and can accurately identify the full box status.
[0033] When the weighing sensor 612 detects that the weight has reached a preset threshold and the box is full, the first controller 614 controls the second cylinder 64 to operate. The first controller 614 receives signals from the photoelectric sensor 68 and the weighing sensor 612 and performs logic control to achieve automatic judgment and automatic switching. The second cylinder 64 provides the swing switching power; its cylinder body is fixed to the bottom of the conveyor frame 61, and its piston rod is fixed to the connecting piece 65. The connecting piece 65 pushes the push plate 66 to rotate, causing the rotating rod 62 and the lever 63 to swing, achieving the effect of quickly switching the material feeding channel and realizing automatic box changing. After box changing, the photoelectric sensor 68 continues to count, repeating the material feeding process to achieve uninterrupted automated boxing. This achieves the effect of continuous boxing and automatic switching when the box is full, greatly improving the automation level and production continuity of pillow packaging.
[0034] Working principle: When the device is in operation, the pillow first enters the second conveyor belt 7 via the first conveyor belt 1. The second controller 10 starts the motor 54, which drives the gear 55 to rotate. The two racks 56 meshing with the gear 55 move synchronously towards each other, causing the connecting plates 51 on both sides to slide towards the center along the limit rod 52 and the slider 53. The connecting plates 51 on both sides drive the push plate 57 and the inclined plate 58 to move closer to the pillow, automatically correcting and centering the pillow to avoid packaging deviation or crooked bags.
[0035] After the pillow is aligned, the pressure plate 9 is driven downward by the third cylinder 8 under the control of the second controller 10 to mechanically compress the bagged pillow, expel most of the air inside the bag, and flatten the pillow to the set thickness. When the third cylinder 8 drives the pressure plate 9 to press down, the pressure plate 9 contacts the inclined surface at the top of the inclined plate 58, squeezing the inclined plate 58 to make the push plate 57 rotate and stretch the second spring 59, so that the push plate 57 is flush with the connecting plate 51. At this time, the pressure plate 9 presses down further, so that the internal groove engages with the connecting plate 51, avoiding mechanical interference between the push plate 57 and the pressure plate 9, and ensuring smooth compression and exhaust.
[0036] After the compression exhaust is completed, the first cylinder 41 drives one side mounting plate 42 to move downwards, and through the rotating plate 45 and the first connecting plate 46, it drives the two side mounting plates 42 to move synchronously toward the packaging bag of the bagged pillow. When the smoothing roller 48 between the second connecting plates 47 contacts the opening of the packaging bag, it adapts to the bag surface under the elastic action of the first spring 49. At the same time, through the squeezing action, the second connecting plate 47 drives the smoothing roller 48 to deflect, and the first spring 49 is stretched as it deflects. The roller press smooths the wrinkles at the bag opening, avoiding poor heat sealing caused by wrinkles.
[0037] Subsequently, the mounting plate 42 continues to press down, causing the heating strip 43 to contact the bag opening. The high-temperature fusion of the plastic film completes the seal. After the sealing is completed, the first cylinder 41 resets, the mounting plate 42 and the smoothing roller 48 are lifted, and the first spring 49 resets the second connecting plate 47, ready for the next operation.
[0038] After compression and sealing, the pressure plate 9 is lifted, the second spring 59 returns to its original position, pushing the inclined plate 58 out to restore the centering state. Then, the motor 54 is started again, driving the connecting plates 51 on both sides to move outward. At this time, the second conveyor belt 7 is started to transport the packaged pillow to the conveyor frame 61. When the photoelectric sensor 68 detects the pillow passing by, it sends a signal to the first controller 614 to accumulate the count. Subsequently, the pillow slides down the conveyor frame 61 and the guide plate 67 onto the pre-placed packaging box on the tray 611. The tray 611 gradually sinks as the weight of the packaging box increases under the support of the third spring 610 and the telescopic guide rod 613. When the third spring 610 is compressed to the point that the bottom of the tray 611 contacts the weighing sensor 612, the weighing sensor 612 detects the weight of the packaging box on the tray 611.
[0039] When the weighing sensor 612 detects that the weight has reached the preset threshold and the box is full, the first controller 614 controls the second cylinder 64 to move, and pushes the push plate 66 to rotate through the connector 65, which drives the rotating rod 62 and the lever 63 to swing, switching to another material feeding channel to realize automatic box changing. After the box is changed, the photoelectric sensor 68 continues to count and repeats the feeding process to realize uninterrupted automated box packing.
[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
