Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of quilt vacuumizing, in particular to a vacuumizing compression and shaping device and method for quilt production. BACKGROUND

[0002] In the process of quilt production, in order to save storage space and improve transportation efficiency, it is usually necessary to perform vacuumizing compression and shaping treatment on the quilt.

[0003] Chinese patent CN218199012U discloses a quilt vacuumizing and packaging shaping machine, a restraint device that restrains the quilt in the packaging bag to make the quilt present a cuboid shape before being vacuumized, a vacuumizing device that is arranged beside the restraint device to perform vacuumizing treatment on the quilt in the packaging bag, and a heat sealing device that is arranged on the restraint device to perform heat sealing on the packaging bag after being vacuumized. The restraint device includes a base, support columns arranged at four corners of the base, a support plate arranged horizontally at the upper end of the support column, a first telescopic cylinder arranged longitudinally at the upper part of the support plate, a telescopic rod of the first telescopic cylinder that is connected in transmission with a press plate arranged horizontally after passing through the support plate, and a fixed baffle and a movable baffle arranged oppositely below the press plate, wherein the movable baffle is connected in transmission with a second telescopic cylinder that can drive the movable baffle to move towards the fixed baffle. Through the above structure, the problem that the quilt in the packaging bag presents a cylindrical shape after being vacuumized and causes a large amount of space waste during boxing is effectively solved.

[0004] The above device restrains the quilt into a cuboid shape through the restraint device, then performs vacuumizing treatment on the quilt in the packaging bag by using the vacuumizing device, and finally performs heat sealing on the packaging bag by using the heat sealing device, thereby completing the entire shaping and packaging process. However, in actual application, this shaping machine still has some deficiencies. Specifically, when the quilt that is not compressed is directly sleeved into the packaging bag, since the quilt itself has a certain expansibility, a larger space needs to be reserved in the packaging bag for the convenience of sleeving. In this way, not only the amount of packaging materials is increased and the packaging cost is increased, but also after the vacuumizing treatment, the excess packaging bag space reserved will form too many wrinkles, which seriously affects the neatness and aesthetics of the packaging.

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in detail below in combination with the drawings and specific embodiments.

[0038] Referring to Figures 1 to 10 The vacuum compression setting device and method for quilt production shown in the figure includes a limiting setting device installed beside the vacuum packaging device 1, the limiting setting device includes a rotating adjusting table 4, a plurality of setting limiting devices 3 are installed on the rotating adjusting table 4, the setting limiting devices 3 are used for limiting and storing the packaging bags 5 and the quilt 6, a pre-compression feeding device 2 is installed beside the setting limiting devices 3, the pre-compression feeding device 2 includes a compression device 21 for extruding the quilt 6, a bag guiding device 22 is installed on the movable end of the compression device 21, the bag guiding device 22 is used for sleeving the packaging bag 5, a horizontal pushing device 23 for pushing the quilt 6 is installed in the compression device 21, and a moving adjusting table 24 for adjusting the position is installed at the bottom of the compression device 21.

[0039] In the process of vacuum packaging quilt 6, first, the folded quilt 6 is placed in the compression device 21. The compression device 21 is started immediately, and the quilt 6 is pre-compressed to reduce its volume and enhance its structural tightness. Then, the guide end of the bag guiding device 22 extends outward, ensuring that the packaging bag 5 can be smoothly and stably sleeved on the outside of the bag guiding device 22. In this step, the design of the guide end ensures the expansion stability of the packaging bag 5 during the sleeving process, providing convenience for the subsequent packaging operation. Subsequently, by moving the adjusting table 24, the worker can accurately adjust the position of the compression device 21 and the bag guiding device 22. This adjustment enables the packaging bag 5 on the bag guiding device 22 to be accurately inserted into the shaping limiting fixture 3. The shaping limiting fixture 3 limits and fixes the packaging bag 5 when it enters its interior, ensuring that it maintains a stable form during the subsequent packaging process. Next, the horizontal pushing device 23 is started, pushing the quilt 6 in the compression device 21 into the interior of the bag guiding device 22. The bag guiding device 22 plays a key role in this process, ensuring that the quilt 6 can smoothly enter the interior of the packaging bag 5 while maintaining a compressed state. After the quilt 6 completely enters the packaging bag 5, the bag guiding device 22 will shrink into the interior of the compression device 21, thereby detaching from the packaging bag 5 and the quilt 6. At this time, the quilt 6 and the packaging bag 5 are fixed and remain in the shaping limiting fixture 3, preparing for the subsequent vacuum packaging operation.

[0040] Finally, by rotating the adjusting table 4, the shaping limiting fixture 3 drives the packaging bag 5 and the quilt 6 to rotate to the position of the vacuum packaging device 1. The vacuum packaging device 1 is started immediately, cooperating with the shaping limiting fixture 3 to perform the shaping and vacuum packaging operation on the packaging bag 5. In this step, the vacuum packaging device 1 uses existing technology to realize the extraction of air in the packaging bag 5 and the heat sealing of the bag opening, thereby completing the entire shaping packaging process. Through the pre-compression packaging method, the device effectively reduces the size and packaging cost of the packaging bag 5, while improving the neatness and aesthetics of the packaging.

[0041] The moving adjusting table 24, the rotating adjusting table 4, and the vacuum packaging device 1 are all existing technologies and will not be described here.

[0042] Referring to Figures 1 to 5 As shown, the compression device 21 includes a limiting guide rail 211 for storing the quilt 6, and two compression plates 212 are slidably installed inside the limiting guide rail 211. The outer side of the compression device 21 is provided with a first double-ball screw sliding table 213 for driving the relative movement of the compression plates 212.

[0043] The compression device 21 is mainly composed of a limiting guide rail 211 for limiting the storage of the quilt 6 and two compression plates 212 slidingly installed inside the limiting guide rail 211. In addition, the outer side of the compression device 21 is also equipped with a first bidirectional ball screw sliding table 213 for driving the relative movement of the compression plates 212.

[0044] In the initial stage of vacuum packaging of the quilt 6, the folded quilt 6 is placed inside the limiting guide rail 211. Then, the first bidirectional ball screw sliding table 213 receives a start signal and starts to work. Through the driving of the first bidirectional ball screw sliding table 213, the two compression plates 212 move relatively along the inside of the limiting guide rail 211, gradually approaching and compressing the quilt 6 located therein. This compression process effectively reduces the volume of the quilt 6 and enhances the compactness of its structure, providing convenience for subsequent packaging operations.

[0045] Referring to Figures 5 to 6 As shown, the bag guiding device 22 includes a plurality of telescopic guide frames 221 distributed on the compression plates 212, the telescopic guide frames 221 are slidingly connected with the compression plates 212, and an adjusting screw 222 is installed between the telescopic guide frames 221 and the compression plates 212, the adjusting screw 222 is threadedly connected with the telescopic guide frames 221, and the bag guiding device 22 further includes a synchronous transmission device 223 for driving the adjusting screw 222 to rotate.

[0046] The synchronous transmission device 223 includes a plurality of first bevel gears 2233 fixedly installed on the adjusting screw 222, and includes a rotary driver 2231 installed on the limiting guide rail 211, an output end of the rotary driver 2231 is installed with a synchronous driving shaft 2232, a plurality of second bevel gears 2234 are slidingly installed on the synchronous driving shaft 2232, the second bevel gears 2234 are rotatably connected with the compression plates 212, and the second bevel gears 2234 are meshed with the first bevel gears 2233.

[0047] In the initial stage of vacuum packaging of the quilt 6, the folded quilt 6 is placed inside the limiting guide rail 211 and is subjected to the pre-compression treatment of the compression device 21. Then, when the bag guiding device 22 needs to work, the rotary driver 2231 is started to drive the synchronous driving shaft 2232 to rotate. The rotation of the synchronous driving shaft 2232 is transmitted to the adjusting screw 222 through the meshing action of the second bevel gears 2234 and the first bevel gears 2233, so that the adjusting screw 222 starts to rotate.

[0048] The rotation of the adjustment screw 222 further drives the telescopic guide frame 221 to slide along the compression plate 212, causing the telescopic guide frame 221 to extend outward. After the telescopic guide frame 221 is extended, the outer portion of the telescopic guide frame 221 is used to expand and support the packaging bag 5. At the same time, the inner portion of the telescopic guide frame 221 serves to guide the compressed quilt 6 smoothly into the packaging bag 5.

[0049] When the quilt 6 completely enters the packaging bag 5, the rotary driver 2231 starts in reverse, driving the synchronous drive shaft 2232 to rotate in the reverse direction, and then drives the adjusting screw 222 to rotate in the reverse direction through the synchronous transmission device 223, so that the telescopic guide frame 221 contracts inward along the compression plate 212, thereby separating from the packaging bag 5 and the quilt 6.

[0050] See also Figures 5 to 7 As shown, the horizontal pushing device 23 includes a horizontal ball screw slide 231 installed on the side of the compression device 21, and a horizontal pushing plate 232 is installed at the movable end of the horizontal ball screw slide 231.

[0051] During the vacuum packaging process of the quilt 6, after the folded quilt 6 has been pre-compressed by the compression device 21, and the bagging guide device 22 has successfully put the packaging bag 5 on and fixed it in the shaping limiter 3, the horizontal pushing device 23 starts to work. After the horizontal ball screw slide 231 receives the start signal, it drives the horizontal pushing plate 232 to move inside the compression device 21. The horizontal pushing plate 232 ensures that the compressed quilt 6 can be effectively pushed from the inside of the compression device 21 to the outside and move stably. During the movement, the horizontal pushing plate 232 maintains close contact with the quilt 6, avoiding the quilt 6 from sliding or deforming during the pushing process. As the horizontal pushing plate 232 continues to move, the compressed quilt 6 is gradually pushed into the interior of the bagging guide device 22. In this process, the bagging guide device 22 plays a key guiding role, ensuring that the quilt 6 can smoothly enter the interior of the packaging bag 5 while maintaining a compressed state. When the quilt 6 is completely inserted into the packaging bag 5 , the horizontal pushing plate 232 stops moving and returns to its initial position, ready for the next pushing operation.

[0052] See also Figure 1 and Figure 8 As shown, guide insertion openings 31 are provided on both sides of the shaping limiter 3, an extrusion assembly 33 is provided on the top of the shaping limiter 3, bag edge clamping devices 34 are provided on the guide insertion openings 31 on both sides, and a pushing and stretching device 32 is also installed on the shaping limiter 3 to push the bag edge clamping device 34 to move.

[0053] The shaping limiting device 3 is designed with two side guide insertion ports 31, which provide a clear access path for the packaging bag 5. When the packaging bag 5 is introduced into the shaping limiting device 3, the two side corners of the packaging bag 5 are precisely positioned through the guide insertion ports 31. The shaping limiting device 3 is equipped with bag edge clamping devices 34 on both sides, which clamp and limit the two side corners of the packaging bag 5, ensuring that the packaging bag 5 remains stable inside the shaping limiting device 3, creating conditions for the quilt 6 to smoothly enter the packaging bag 5.

[0054] After the pre-compression feeding device 2 combines the packaging bag 5 and the quilt 6 in the shaping limiting device 3, the rotating adjustment platform 4 is started, driving the entire shaping limiting device 3 to rotate to the working position of the vacuum packaging device 1. At this time, the vacuum packaging device 1 begins to perform the packaging task. During this process, the extrusion assembly 33 at the top of the shaping limiting device 3 plays a role, applying moderate pressure to the packaging bag 5 and the quilt 6 inside it to maintain its stable form during the vacuuming process.

[0055] At the same time, the push and stretch device 32 installed on the shaping limiting device 3 is started, pushing the two side bag edge clamping devices 34 to move elastically to both sides. By elastically pressing to both sides, the excess packaging bag 5 material caused by the compression of the quilt 6 is pulled and stretched to both sides, effectively reducing the possibility of wrinkles on the packaging bag 5 during the vacuuming process.

[0056] Referring to Figure 8 and Figure 9 , the extrusion assembly 33 includes a first linear actuator 331 installed on the shaping limiting device 3, and a pressure pushing plate 332 is installed on the output end of the first linear actuator 331. The pressure pushing plate 332 is slidably installed with a pressure pushing plate 333, and a plurality of first pressure springs 334 are installed between the pressure pushing plate 333 and the pressure pushing plate 332.

[0057] During the vacuum packaging process, after the shaping limiting device 3 rotates to the working position of the vacuum packaging device 1, the first linear actuator 331 is started to drive the pressure pushing plate 332 to move towards the packaging bag 5 and the quilt 6 inside it. At this time, the pressure pushing plate 333 on the pressure pushing plate 332 moves with it, and due to the elastic action of the first pressure spring 334, it maintains a certain elastic contact with the pressure pushing plate 332.

[0058] The pressure pushing plate 333 directly acts on the packaging bag 5 and the quilt 6 inside it, and through the elastic force of the first pressure spring 334, it applies moderate pressure to the packaging bag 5 and the quilt 6 inside it. This pressure not only helps to maintain the stable form of the packaging bag 5 and the quilt 6 inside it during the vacuuming process, but also to a certain extent, adapts to different thickness and material of the quilt 6, ensuring the stability and adaptability of the pressure.

[0059] The first pressure spring 334 enables the pressure pushing plate 333 to perform a certain degree of elastic adjustment according to the actual compression of the quilt 6 while applying pressure, thereby avoiding excessive pressure damage to the packaging bag 5 and the quilt 6 inside it.

[0060] See also Figure 8 and Figure 9 As shown, the bag edge clamping device 34 includes a movable bottom plate 341 slidably mounted on the side of the shaping limiter 3 , a second linear drive 343 is mounted on the movable bottom plate 341 , and a downward clamping plate 342 is mounted on the output end of the second linear drive 343 .

[0061] In the operation process, the packaging bag 5 is first introduced into the interior of the shaping limiter 3, and the packaging bag 5 is guided to pass through the guide holes 31 on both sides. When the packaging bag 5 is properly placed in the designated position, its two side corners are exactly located between the movable bottom plate 341 and the downward clamping plate 342. At this time, the second linear drive 343 is activated, driving the downward clamping plate 342 to descend in the vertical direction. As the downward clamping plate 342 descends, it gradually approaches and eventually clamps the two side corners of the packaging bag 5, thereby achieving effective fixation of the packaging bag 5. The stable position of the packaging bag 5 inside the shaping limiter 3 is ensured, providing the necessary stability guarantee for the subsequent quilt 6 loading process. During the vacuum packaging stage, the pushing and stretching device 32 starts working, pushing the movable bottom plate 341 to move in the horizontal direction. Since the movable bottom plate 341 and the downward clamping plate 342 jointly clamp the two side corners of the packaging bag 5, the movement of the movable bottom plate 341 will drive the packaging bag 5 to stretch to both sides. This stretching effect effectively reduces wrinkles on the packaging bag 5 caused by material redundancy during the vacuuming process, thereby improving the overall quality and appearance of the product.

[0062] See also Figures 8 to 10 As shown, the pushing and stretching device 32 includes a second bidirectional ball screw slide 321 installed on the side of the shaping limiter 3, and two telescopic pushing columns 322 are installed at the movable end of the second bidirectional ball screw slide 321. A movable push block 323 is installed on each telescopic pushing column 322, and the movable push block 323 is fixedly connected to the movable bottom plate 341. A second pressure spring 324 is installed between the telescopic pushing column 322 and the movable push block 323.

[0063] During the vacuum packaging phase, when the packaging bag 5 needs to be stretched to reduce wrinkles, the push-stretching device 32 is activated. Upon receiving this command, the second bidirectional ball screw slide 321 begins to drive the two telescopic push posts 322 to move synchronously in opposite directions. As the telescopic push posts 322 move, the second pressure spring 324 applies a thrust to the movable push block 323. This thrust forces the movable push block 323 to move horizontally, driving the movable base plate 341 to which it is fixed.

[0064] Because the movable bottom plate 341 and the downward clamping plate 342 of the bag edge clamping device 34 jointly clamp the two side corners of the packaging bag 5, the movement of the movable bottom plate 341 directly causes the packaging bag 5 to be stretched in both directions. This stretching effect not only effectively reduces wrinkles caused by redundant material during the vacuuming process of the packaging bag 5, but also ensures the stable shape of the packaging bag 5 inside the shaping and limiting device 3.

[0065] Through the precise control of the second bidirectional ball screw slide 321 and the elastic action of the second pressure spring 324, the pushing and stretching device 32 can achieve precise stretching and stable control of the packaging bag 5, thereby improving the overall quality and appearance of the product.

[0066] See also Figure 1 and Figure 2 As shown, both sides of the packaging bag 5 are provided with shaping edges 51.

[0067] With the start-up of the pre-compression feeding device 2, the folded quilt 6 is placed in the compression device 21 and pre-compressed. Subsequently, the guide end of the bagging guide device 22 extends outward, and the packaging bag 5 is smoothly and stably put on the outside of the bagging guide device 22 under the guidance of the guide end. Through the precise adjustment of the movable adjustment table 24, the packaging bag 5 on the bagging guide device 22 can be accurately inserted into the shaping limiter 3. Through the guide insertion openings 31 set on both sides of the shaping limiter 3, the shaping edges 51 on both sides of the packaging bag 5 are precisely positioned. At this time, the bag edge clamping device 34 is started to clamp the shaping edges 51 on both sides of the packaging bag 5 to ensure that the packaging bag 5 remains stable inside the shaping limiter 3.

[0068] As the quilt 6 is pushed into the packaging bag 5, the bag edge clamping device 34 continuously clamps the shaped edges 51 on both sides of the packaging bag 5, ensuring that the quilt 6 can smoothly enter the packaging bag 5 while maintaining its compressed state. After the quilt 6 is completely in the packaging bag 5, the bagging guide device 22 contracts toward the inside of the compression device 21, thereby separating from the packaging bag 5 and the quilt 6.

[0069] At this point, the squeezing assembly 33 at the top of the shaping and limiting device 3 applies moderate pressure to the packaging bag 5 and the quilt 6 inside it to maintain their shape during the vacuuming process. Simultaneously, the pushing and stretching device 32 is activated, pushing the bag edge clamping devices 34 on both sides to elastically press and move toward the sides. By stretching the bag 5 toward the sides, any wrinkles that may appear during the vacuuming process are effectively reduced.

[0070] Under the action of the vacuum packaging device 1, the air in the packaging bag 5 is extracted, and the bag opening is heat sealed, thereby completing the entire shaping packaging process. Through this process, the packaging bag 5 not only realizes effective packaging of the quilt 6, but also ensures the stability of the packaging process and the beauty of the packaging effect through the cooperation of the two sides of the shaping pull edge 51 and the bag edge clamping device 34.

[0071] A method for using a vacuum compression shaping device for quilt production, comprising the following steps:

[0072] S1, place the folded quilt 6 in the compression device 21 of the pre-compression feeding device 2, then start the compression device 21 to pre-compress the quilt 6, reduce the volume of the quilt 6 and enhance the structural tightness.
