Description

Technical Field

[0001] The utility model relates to the technical field of mattress packaging, in particular to a vacuum compression device for a spring mattress. Background Art

[0002] Spring mattresses, commonly known as "Simmons," are a common and high-performance mattress type used today. Their core is composed of springs, providing excellent support, helping to alleviate pain and stiffness, and ensuring adequate support. Specifically, the three-section, independent springs, designed strictly according to ergonomic principles, flexibly adapt to the body's curves and weight, evenly supporting every part of the body and maintaining a naturally straight spine. High-quality spring mattresses offer a long lifespan, maintaining their shape and elasticity over time, eliminating the need for frequent replacement. Spring mattresses also offer excellent breathability, helping to regulate body temperature and maintain a dry and comfortable sleeping environment.

[0003] After the mattress is processed, it needs to be packed into a bag, compressed, and then sealed to reduce the volume of the mattress for easy transportation. Currently, in most cases, the bag is evacuated into a vacuum state by a vacuum pump and then sealed by a sealing device. The entire process requires two devices to be implemented, which has low work efficiency and high production costs. Therefore, it is particularly important to improve the existing vacuum compression device and design a new spring mattress vacuum compression device to solve the above technical defects and improve the practicality of the overall vacuum compression device.

[0027] The sealing assembly 2 is used to seal the film wrapped at both ends of the mattress. The sealing assembly 2 consists of a first connecting frame 5, a first mobile frame 6, a second mobile frame 7, two groups of first heat-sealing blocks 8 and a cutter 9. The first connecting frame 5 is fixedly connected to the front end of the conveying frame body 1, the first mobile frame 6 is slidably connected to the inside of the first connecting frame 5, the second mobile frame 7 is slidably connected to the inside of the first connecting frame 5 and is located below the first mobile frame 6, the two groups of first heat-sealing blocks 8 are respectively fixedly connected to the ends of the first mobile frame 6 and the second mobile frame 7 that are close to each other, and the cutter 9 is slidably connected to the inside of the first mobile frame 6;

[0028] The film covering component 3 is used to cover the mattress;

[0029] The compression assembly 4 is used to perform vacuum compression on the mattress after the film is coated.

[0030] Furthermore, the upper and lower ends of the first connecting frame 5 are fixedly connected to the first telescopic cylinder, and the driving end of the first telescopic cylinder extends to the interior of the first connecting frame 5 and is fixedly connected to the connecting plate 10. The two groups of connecting plates 10 are fixedly connected to the first movable frame 6 and the second movable frame 7 respectively away from the driving ends of the two groups of first telescopic cylinders. The first telescopic cylinder is started to drive the connecting plate 10 to move, so that the first movable frame 6 and the second movable frame 7 are moved. When the first movable frame 6 and the second movable frame 7 are moved, the two groups of first heat sealing blocks 8 are brought into contact, and both ends of the film are placed between the two groups of first heat sealing blocks 8. The film can be sealed by the first heat sealing blocks 8.

[0031] Among them, a accommodating cavity 11 is opened at the top of the second movable frame 7, and two sets of second telescopic cylinders are fixedly connected to the top of the first movable frame 6. The driving end of the second telescopic cylinder is fixedly connected to the cutter 9, and both ends of the top of the second movable frame 7 are fixedly connected to the limiting rod 12. When sealing the film, the second telescopic cylinder is started to drive the cutter 9 to move, and the cutter 9 is moved to the inside of the accommodating cavity 11, so that the film can be cut, so that the film wraps the mattress, and the open end of the film is connected to the limiting rod 12, so that the film can be connected to the first connecting frame 5.

[0032] Secondly, the coating assembly 3 consists of a connecting frame 13, a placement roller 14 and multiple sets of guide rollers 15. The connecting frame 13 is fixedly connected to the top of the conveying frame body 1 and close to one end of the first connecting frame 5. The placement roller 14 is rotatably connected to the inside of the connecting frame 13. The multiple sets of guide rollers 15 are all rotatably connected to the inside of the connecting frame 13 and are located below the placement roller 14. The coating assembly 3 can be used to coat the upper and lower ends of the mattress and package it.

[0033] Furthermore, the placement roller 14 and the guide roller 15 extend to the outside of the connecting frame 13 and are fixedly connected to a driving gear 16.

When the fourth telescopic cylinder is started, the third movable frame 21 is driven to move, so that the second heat sealing block 22 on its outer side is moved and contacts with another group of second heat sealing blocks 22, thereby heat-sealing the two ends of the film.

[0036] The film roll outside the placing roller 14 is rotated to extend the film. At the same time, when the placing roller 14 rotates, the driving gear 16 is driven to rotate, so that the transmission belt 17 is displaced, and the remaining driving gears 16 are driven to rotate, thereby rotating the multiple guide rollers 15. The film can be guided by the guide rollers 15 so that the film can contact the mattress. The first telescopic cylinder is started to drive the connecting plate 10 to displace, so that the first movable frame 6 and the second movable frame 7 are displaced.

The film can be sealed by the first heat-sealing blocks 8. When the film is sealed, the second telescopic cylinder is started to drive the cutter 9 to move, and the cutter 9 is moved to the inside of the accommodating chamber 11, so that the film can be cut, so that the film wraps the mattress, and at the same time, the mattress can be moved, and the conveying frame body 1 is moved to the bottom of the fixed frame 18, and the third telescopic cylinder is started to drive the pressure plate 19 to move, so that the pressure plate 19 can compress the mattress and discharge the gas inside the mattress, so that the mattress is vacuum compressed, and the fourth telescopic cylinder is started to drive the third movable frame 21 to move, so that the second heat-sealing block 22 on its outer side is displaced and contacts with another group of second heat-sealing blocks 22, so that the two ends of the film are heat-sealed, so that the mattress can be vacuum-compressed and packaged. Compared with the existing vacuum compression device, the utility model can improve the overall practicality of the vacuum compression device through design.
