Description

Technical Field

[0001] This invention relates to the field of storage and packaging technology, and more particularly to a bedding packaging device. Background Technology

[0002] Currently, bedding products (such as quilts, sheets, duvet covers, pillowcases, etc.) are typically packaged in vacuum compression bags during production, sales, and daily storage. Vacuum compression bags significantly reduce the volume of items by removing air from the bag, thereby saving storage and transportation space.

[0003] With the popularization of online retail, the demand for returns and exchanges of bedding products is increasing. When returning or exchanging products, consumers need to repack the bedding products that have been opened and used into the original packaging. However, the existing packaging method is mostly disposable vacuum compression bags placed in boxes. Once opened, repackaging is extremely inconvenient. Vacuum compression bags are difficult to restore to their original shape without the help of equipment. After users open the packaging, they simply fold the bags and put them back in, which causes the volume to expand and makes it difficult to put them back into the original packaging. This makes it difficult for consumers to pack the products when returning them.

[0004] To address the aforementioned problems, a bedding packaging device is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a bedding packaging device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bedding packaging device includes an outer cylinder with an external thread on its top outer wall and an inner cylinder slidably disposed on the inner side of the outer cylinder. The device is characterized in that a storage assembly is disposed on the inner side of the inner cylinder, the storage assembly including a limiting disk slidably disposed on the inner side of the inner cylinder, a driving disk rotatably connected to the top of the limiting disk, a plurality of clamping heads equidistantly disposed circumferentially between the driving disk and the limiting disk, and an mounting ring constraining the plurality of clamping heads.

[0008] A snap fastener is fixedly connected to the bottom outer side of the inner cylinder, and a snap fastener is fixedly connected to the bottom inner side of the outer cylinder. The snap fastener and the snap fastener cooperate and engage with each other, and there is a restoring force between the snap fastener and the snap fastener.

[0009] A base cylinder is fixedly installed at the bottom of the outer cylinder, and a winding assembly is provided on the inner side of the base cylinder. The winding assembly includes several winding rollers that are circumferentially equidistant and rotate. A guide ring is movably provided on the top of the winding rollers. The winding rollers are used to drive the inner cylinder to retract and move.

[0010] The above technical solution further includes:

[0011] The bottom of the snap fastener is fixedly connected with several first mounting buckles and first connecting buckles at equal intervals in the circumference. A limiting sleeve is fixedly provided at the bottom center of the snap fastener. The top of the snap fastener is fixedly connected with second mounting buckles and second connecting buckles at equal intervals in the circumference. A limiting hollow rod is fixedly provided at the top center of the snap fastener. A fastening spring is installed between the first mounting buckles and the second mounting buckles. When the first connecting buckle and the second connecting buckle are fastened together, the limiting sleeve is nested on the outside of the limiting hollow rod.

[0012] The storage assembly also includes a fixing plate fixedly connected to the top of the mounting ring, and a sleeve film fixedly connected to the top of the fixing plate for covering bedding.

[0013] The fixing plate and the mounting ring are provided with a number of vent holes in the same circumferential direction. The inner side wall of the mounting ring is provided with a number of mating grooves at equal intervals in the circumferential direction. The clamping head and the mounting ring are jointly installed with a limit bolt, which is located inside the mating groove.

[0014] The drive disk has several drive slots that are equidistantly spaced around the circumference, and the limiting disk has several limiting slots that are equidistantly spaced around the circumference. A limiting slider is provided between the drive slots and the limiting slots to limit sliding, and the limiting slider is fixedly connected to the clamping head.

[0015] The limiting plate has several mounting slots through it. A mounting plate is fixedly connected to the inner side of the mounting slot. A limiting spring is fixedly connected to the mounting plate on the inner side of the mounting slot. A limiting ball is fixedly connected to the other end of the limiting spring. Several sets of ball grooves are equidistantly opened on the bottom of the drive plate. Each set of ball grooves contains multiple ball grooves. The limiting spring and the ball grooves are mutually compatible.

[0016] Several cables are fixedly connected to the bottom of the drive disc. The cables pass through the limiting sleeve and the limiting hollow rod, and the other end of the cables is fixedly connected to the take-up roller.

[0017] The winding assembly also includes a bevel gear disc rotatably connected to the bottom inner side of the base cylinder. A handwheel is detachably provided at one end of the bevel gear disc extending to the outside of the base cylinder. Several bevel gears are circumferentially meshed on the bevel gear disc. Several sets of bearing plates are circumferentially fixedly connected to the bottom inner side of the base cylinder, and each set of bearing plates consists of two plates. Each set of bearing plates is rotatably connected to the take-up roller, and the bevel gears are fixedly connected to the take-up roller.

[0018] A reciprocating screw is rotatably connected between the two bearing plates in each group.

A crescent-shaped pin is threaded onto the reciprocating screw, and the crescent-shaped pin is fixedly connected to the guide ring. A limit plate is fixedly connected between the two bearing plates in each group, and the limit plate slides with the crescent-shaped pin.

[0019] The present invention has the following beneficial effects:

[0020] 1. In this invention, by cooperating with the storage component and the winding component, and by using the vent hole to expel air when the cover is taken in, a gap is formed to reduce friction, so that the operator can conveniently put the bedding into the cover without vacuum equipment, and the bedding is driven into the inner cylinder by the winding roller, and then the closing buckle and the fixing buckle are rotated to lock it, which greatly facilitates the return and repacking.

[0021] 2. In this invention, the winding roller is driven by a reversing gear to drive the reciprocating screw, which causes the crescent-shaped pin block to drive the guide ring to evenly distribute the cable, avoiding tangling and jamming, and ensuring that the film slides smoothly into the depth of the inner cylinder to achieve tight storage.

[0034] The technical solutions of 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.

[0035] Example 1

[0036] like Figures 1-11 As shown, the present invention proposes a bedding packaging device, including an outer cylinder 1, an inner cylinder 10 slidably disposed on the inner side of the outer cylinder 1, a storage component disposed on the inner side of the inner cylinder 10, the storage component including a limiting disk 33 slidably disposed on the inner side of the inner cylinder 10, a driving disk 32 rotatably connected to the top of the limiting disk 33, a plurality of clamping heads 36 being equidistantly disposed in the circumferential direction between the driving disk 32 and the limiting disk 33, and an installation ring 31 being provided for limiting the plurality of clamping heads 36.

[0037] The bottom outer side of the inner cylinder 10 is fixedly connected to a snap fastener 12, and the bottom inner side of the outer cylinder 1 is fixedly connected to a snap fastener 13. The snap fastener 12 and the snap fastener 13 cooperate to fasten each other, and there is a restoring force between the snap fastener 12 and the snap fastener 13.

[0038] A base cylinder 2 is fixedly installed at the bottom of the outer cylinder 1. A winding assembly is provided on the inner side of the base cylinder 2. The winding assembly includes several winding rollers 26 that are circumferentially equidistantly rotatable. A guide ring 21 is movably provided on the top of the winding rollers 26. The winding rollers 26 are used to drive the inner cylinder 10 to retract and move.

[0039] Traditional packaging devices often use vacuum compression packaging for items, which is inconvenient for customers who need to exchange or return goods. Therefore, this design allows customers to refill the bedding by first taking out the storage component to the port of the inner cylinder 10, then removing the mounting ring 31, then winding the bedding into a cylinder, placing it into the sleeve 3 on the mounting ring 31, and tightening the port of the sleeve 3. The mounting ring 31 is then fixed to the drive plate 32. The winding assembly is then used to drive the sleeve 3 containing the bedding into the inner cylinder 10. Finally, the inner cylinder 10 is rotated to engage the locking buckle 12 and the fixing buckle 13. The operation is more convenient.

[0040] Example 2

[0041] like Figures 7-11 As shown, based on Embodiment 1, in this embodiment, the bottom of the disc buckle 12 is fixedly connected with a plurality of first mounting buckles 120 and first connecting buckles 121 at equal intervals. A limiting sleeve 122 is fixedly provided at the bottom center of the disc buckle 12. The top of the fixed disc buckle 13 is fixedly connected with a second mounting buckle 130 and a second connecting buckle 131 at equal intervals. A limiting hollow rod 133 is fixedly provided at the top center of the fixed disc buckle 13. A fastening spring 14 is installed between the first mounting buckles 120 and the second mounting buckles 130. The first connecting buckle 121 and the second connecting buckle 131 are fastened together.

[0042] Furthermore, during the assembly process of the snap fastener 12 and the fixed snap fastener 13, the snap fastener 12 needs to be pressed down close to the fixed snap fastener 13. During this process, the first snap fastener 121 and the second snap fastener 131 are misaligned. When the first snap fastener 121 and the second snap fastener 131 approach each other and make contact, the snap fastener 12 is rotated so that the first snap fastener 121 enters the inner side of the second snap fastener 131 from one side to achieve locking and fixing. At this time, the limiting sleeve 122 is nested on the outer side of the limiting hollow rod 133, and the locking spring 14 is compressed.

[0043] The storage assembly also includes a fixing plate 30 fixedly connected to the top of the mounting ring 31, and a cover 3 fixedly connected to the top of the fixing plate 30, which is used to cover the bedding.

[0044] Furthermore, at the start of operation, the buckling spring 14 is in a free state, the inner cylinder 10 extends a certain length beyond the outer cylinder 1, and the winding roller 26 of the winding assembly is in a free state. The cable 210 can move with the fixing plate 30. The operator pulls the sleeve 3 and pulls the fixing plate 30 to the port of the inner cylinder 10. The operator first releases the fixing of the limit bolt 34, and then rotates the drive disk 32 to make the clamping head 36 exit the mating groove 35. The installation ring 31 can then be removed. The sleeve 3 is a plastic film tube bag with a certain strength, and its bottom opening edge is fixed to the fixing plate 30.

[0045] Furthermore, the inner cylinder 10 is first placed horizontally. The operator lays out the bedding to be stored and manually rolls it into a tight cylinder. This cylinder is then placed inside the removed sleeve 3. Subsequently, the operator manually gathers and tightens the top end of the sleeve 3, so that the bedding is wrapped inside the sleeve 3. At this point, the sleeve 3 containing the items forms a single assembly with the fixing plate 30 and the mounting ring 31.

[0046] The drive disk 32 has several drive slots 37 that are equidistantly spaced around the circumference, and the limiting disk 33 has several limiting slots 38 that are equidistantly spaced around the circumference. A limiting slider 39 is provided between the drive slots 37 and the limiting slots 38 to limit sliding. The limiting slider 39 is fixedly connected to the clamping head 36.

[0047] The fixing plate 30 and the mounting ring 31 are provided with a number of vent holes 315 in the same circumferential direction. The inner side wall of the mounting ring 31 is provided with a number of mating grooves 35 at equal intervals in the circumferential direction. The clamping head 36 and the mounting ring 31 are jointly installed with a limit bolt 34, which is located inside the mating groove 35.

[0048] Furthermore, the operator places the mounting ring 31 with the item back into the port of the inner cylinder 10, and adjusts the position of the clamping head 36 to the edge of the drive disk 32 by rotating the drive disk 32, so that the bottom surface of the mounting ring 31 is attached to the drive disk 32, and the clamping head 36 is embedded in the mating groove 35 of the inner side wall of the mounting ring 31. Then, the mounting ring 31 is rotated until there is resistance, and the mounting ring 31 and the clamping head 36 are fixed by the limit bolt 34.

[0049] The limiting plate 33 has several mounting slots 311 through it. The mounting plate 312 is fixedly connected to the inner side of the mounting slot 311. The limiting spring 314 is fixedly connected to the mounting plate 312 on the inner side of the mounting slot 311. The other end of the limiting spring 314 is fixedly connected to the limiting ball 310. The bottom of the drive plate 32 has several sets of ball grooves 313 equidistantly opened, and each set of ball grooves 313 has multiple numbers. The limiting spring 314 and the ball grooves 313 are mutually compatible.

[0050] Furthermore, when the drive disk 32 rotates to the preset clamping position, the limit spring 314 pushes the limit ball 310 outward, so that the limit ball 310 is accurately inserted into the ball groove 313 opened at the corresponding position at the bottom of the drive disk 32, ensuring that the clamping force of the clamping head 36 is constant.

[0051] Several cables 210 are fixedly connected to the bottom of the drive disc 32. The cables 210 pass through the limiting sleeve 122 and the limiting hollow rod 133. The other end of the cables 210 is fixedly connected to the take-up roller 26.

[0052] Furthermore, due to the increased volume of the items inside the manually wound film 3, it becomes inconvenient to retract the film 3 into the inner cylinder 10. The winding assembly pulls the limiting disc 33 to move. The end of the inner cylinder 10 is designed with a tapered opening. When the film 3 enters the inner cylinder 10 and is squeezed, excess air inside the film 3 is expelled. When the film 3 enters the inner cylinder 10, the expanded film 3 contacts the inner wall of the inner cylinder 10, resulting in significant friction. Through the exhaust hole 315, when the mounting ring 31 and the fixing plate 30 move downward, the air between the limiting disc 33 and the bottom of the inner cylinder 10 is discharged through the exhaust hole 315. The airflow flows over the surface of the film 3, creating a gap between the film 3 and the inner wall of the inner cylinder 10, reducing friction and ensuring that the film 3 can overcome resistance and continue to move downward smoothly until it completely slides into the depth of the inner cylinder 10.

[0053] Example 3

[0054] like Figures 3-5 As shown, based on the above embodiments, in this embodiment, the winding assembly further includes a bevel gear disk 22 rotatably connected to the bottom inner side of the base cylinder 2. A handwheel 20 is detachably provided at one end of the bevel gear disk 22 extending to the outside of the base cylinder 2. Several bevel gears 24 are circumferentially meshed at equal intervals on the bevel gear disk 22. Several sets of bearing plates 23 are circumferentially fixedly connected to the bottom inner side of the base cylinder 2, and each set of bearing plates 23 consists of two bearing plates. Each set of bearing plates 23 is rotatably connected to the take-up roller 26, and the bevel gears 24 are fixedly connected to the take-up roller 26.

[0055] A reciprocating screw 27 is rotatably connected between the two bearing plates 23 in each group. A reversing gear 25 is fixedly connected to both the reciprocating screw 27 and the take-up roller 26, and the two reversing gears 25 mesh with each other. A crescent-shaped pin 28 is threadedly connected to the reciprocating screw 27. The crescent-shaped pin 28 is fixedly connected to the guide ring 21. A limit plate 29 is fixedly connected between the two bearing plates 23 in each group, and the limit plate 29 slides with the crescent-shaped pin 28.

[0056] Furthermore, the handwheel 20 is installed in the internal hexagonal groove at the bottom of the bevel gear plate 22. The bevel gear plate 22 drives the take-up roller 26 to rotate, and the two reversing gears 25 mesh to drive the reciprocating screw 27 on the adjacent bearing plate 23 to rotate synchronously. The crescent-shaped pin block 28 is threadedly connected to the reciprocating screw 27, and the rotational freedom of the crescent-shaped pin block 28 is restricted by the limiting plate 29. Therefore, the crescent-shaped pin block 28 can only move in a reciprocating linear motion along the axial direction of the reciprocating screw 27. The guide ring 21, which is fixedly connected to the crescent-shaped pin block 28, moves together and moves back and forth above the take-up roller 26, arranging the cable 210 neatly and evenly layer by layer on the surface of the take-up roller 26. This effectively prevents the cable 210 from getting tangled and jammed due to local accumulation, ensuring the continuous smoothness of the winding action.

[0057] Furthermore, due to the friction between the sleeve 3 and the inner cylinder 10, when the winding assembly drives the sleeve 3 to move, the sleeve 3 can drive the inner cylinder 10 to move. When the inner cylinder 10 descends to the lowest position, the operator stops cranking the handwheel 20 and holds the outer wall of the inner cylinder 10 and rotates it slightly by an angle so that the first buckle 121 at the bottom of the snap fastener 12 aligns with the second buckle 131 at the top of the fixed snap fastener 13.

[0058] Furthermore, the first buckle 121 and the second buckle 131 automatically engage and lock together, and the limiting sleeve 122 is once again completely nested on the outside of the limiting hollow rod 133. The two work together to play the role of axial limiting and anti-swaying.

[0059] Furthermore, the bevel gear disc 22 is then rotated until the limiting disc 33 moves to the bottom of the inner cylinder 10. At this point, there will be significant resistance when rotating the bevel gear disc 22. The bedding is tightly compressed and completely stored inside the outer cylinder 1. The top outer wall of the outer cylinder 1 is provided with an external thread 11. The matching end cap is installed on the external thread 11, and then the handwheel 20 is fixed to the base cylinder 2 with bolts to prevent the bevel gear disc 22 from rotating on its own.

[0060] 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.
