Description

Technical Field

[0001] The utility model belongs to the field of mattress packaging equipment, in particular to a compression sealing packaging component of a polyolefin sponge packaging production line. Background Art

[0002] Polyolefin sponge packaging and sealing equipment is an essential component of mattress production lines, dedicated to efficiently and accurately completing mattress packaging and sealing operations. However, a significant shortcoming of the existing equipment is the lack of a compression mechanism. This omission directly results in the bulk of the packaged mattresses, which not only takes up a large amount of storage space and increases warehousing costs, but also creates numerous inconveniences and increases transportation costs. Furthermore, uncompressed mattresses are prone to rupturing the packaging bags due to bumps and squeezing during transportation, compromising the overall aesthetics and protective properties of the product.

The telescopic end of the pressing cylinder extends downward and is fixedly installed with an upper mounting seat, and an upper hot pressing rod matching the lower hot pressing rod is fixedly installed on the lower surface of the upper mounting seat.

[0006] Among them, the compression sealing packaging component of the polyolefin sponge packaging production line also includes two groups of horizontal synchronization components and two groups of vertical synchronization components. The horizontal synchronization components and the vertical synchronization components have the same structure and both include synchronization shafts, synchronization gears, fixed bearings and synchronization racks. Synchronization gears are fixedly installed at both ends of the synchronization shaft. The synchronization shaft is installed with a fixed bearing on one side of the synchronization gear. The synchronization shaft is rotatably connected to the compression component through the fixed bearing. A synchronization rack is meshed with one side of the synchronization gear. The extension direction of the synchronization rack is parallel to the compression movement direction of the compression component. The synchronization rack is fixedly installed on the frame.

[0009] The utility model has the beneficial effects:

[0010] 1. A compression component is set in the packaging component to compress the polyolefin sponge pad before packaging, squeezing out the air inside and reducing the volume of the polyolefin sponge pad, thereby reducing the space it occupies and facilitating transportation and storage.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] As attached Figure 1-6 The compression sealing packaging assembly of a polyolefin sponge packaging production line shown includes a frame 1, on which four guide shafts 2 are fixedly mounted. The four guide shafts 2 are symmetrically mounted on both sides of the frame 1, with two guide shafts 2 on each side. A guide slider 3 is slidably mounted on each guide shaft 2. The four guide sliders 3 are jointly fixed with the same compression assembly 4, so that the compression assembly 4 can be mounted on the frame 1 so as to slide up and down. The cooperation between the guide slider 3 and the guide shaft 2 improves the lifting stability and smoothness of the compression assembly 4. Two lifting cylinders 5 serving as drive assemblies and driving the compression assembly 4 to slide up and down are also fixedly mounted on the top of the frame 1. The telescopic ends of the lifting cylinders 5 are fixedly connected to the upper surface of the compression assembly 4. A feeding assembly 6 is installed on the frame 1 below the compression assembly 4. The feeding assembly 6 includes a feeding motor 7, four feeding rollers 8 and a feeding belt 9. The four feeding rollers 8 are rotatably installed on the frame 1, and the four feeding rollers 8 are arranged in a rectangular shape to form a cube. The four feeding rollers 8 are the four sides of the cube respectively. The four feeding rollers 8 are equipped with the same feeding belt 9. One end of one of the feeding rollers 8 is connected to a worm gear transmission box 10 for transmission connection. The worm gear transmission box 10 is fixedly installed on the frame 1. The feeding motor 7 and the worm gear transmission box 10 are connected for transmission. The feeding rollers 8 are driven to rotate by the feeding motor 7, thereby driving the feeding belt 9 to rotate to realize feeding.

[0020] One end of the compression assembly 4 is equipped with an upper hot pressing assembly 11, and one end of the feeding assembly 6 is equipped with a lower hot pressing assembly 12 that matches the upper hot pressing assembly 11; the lower hot pressing assembly 12 includes a lower mounting seat 13, the lower mounting seat 13 is fixedly connected to the feeding assembly 6, and the upper surface of the lower mounting seat 13 is fixedly mounted with a lower hot pressing rod 14; the upper hot pressing assembly 11 includes two cylinder seats 15 fixedly mounted to the compression assembly 4, each cylinder seat 15 is fixedly mounted with a pressing cylinder 16, the telescopic ends of the two pressing cylinders 16 extend downward and are fixedly mounted with the same upper mounting seat 17, and the lower surface of the upper mounting seat 17 is fixedly mounted with an upper hot pressing rod 18 that matches the lower hot pressing rod 14.

[0021] As a preferred embodiment, two groups of horizontal synchronization components and two groups of vertical synchronization components are also installed between the frame 1 and the compression assembly 4. The horizontal synchronization components and the vertical synchronization components have the same structure and both include a synchronization shaft 19, a synchronization gear 20, a fixed bearing 27 and a synchronization rack 28. Synchronization gears 20 are fixedly installed at both ends of the synchronization shaft 19. A fixed bearing 27 is installed on each side of the synchronization shaft 19 where the two synchronization gears 20 are close to each other. The synchronization shaft 19 is rotatably connected to the upper surface of the compression assembly 4 through the fixed bearing 27. A synchronization rack 28 is meshed with each other on one side of each synchronization gear 20. The synchronization rack 28 is fixedly connected to the frame 1. The extension direction of the synchronization rack 28 is parallel to the compression movement direction of the compression assembly 4, that is, parallel to the guide shaft 2. Two groups of horizontal synchronization components and two groups of vertical synchronization components are arranged at intervals and connected end to end to form a rectangular synchronization structure. The rectangular area of the synchronization structure matches the rectangular area of the compression component 4. The rectangle of the synchronization structure is slightly smaller than the rectangle of the compression component 4, so that the cooperation of the two groups of horizontal synchronization components and the two groups of vertical synchronization components can cover the four sides of the upper surface of the entire compression component 4 as much as possible, thereby realizing the horizontal synchronous lifting and lowering of the compression component 4.

[0022] As a preferred embodiment, a mounting rod 21 is fixedly mounted on one side of one of the guide shafts 2. An upper travel switch 22 and a lower travel switch 23 are fixedly mounted on the mounting rod 21. The upper travel switch 22 and the lower travel switch 23 respectively contact and cooperate with the guide slider 3 to limit the maximum travel of the guide slider 3. Both travel switches are connected to the control component of the production line and cooperate with the control component to achieve automated lifting control. A counting gear 24 is coaxially mounted on one side of one of the synchronous gears 20. The counting gear 24 is connected to a counter 26 via a toothed belt 25. The counter 26 is also connected to the control component to digitize the rotation of the synchronous shaft 19, which facilitates calculation and control by the control component and is also convenient for staff to view.

[0023] The compression-sealing packaging assembly provided in this embodiment is part of a packaging production line. The feeding assembly 6 is connected to upstream equipment and receives polyolefin sponges already enclosed in plastic packaging bags from the upstream equipment. It then delivers the bagged polyolefin sponges to directly below the compression assembly 4. At this point, the lifting cylinder 5 is activated by a numerically controlled device, driving the compression assembly 4 to descend rapidly. As the compression assembly 4 approaches the polyolefin sponge, it decelerates and makes contact with it, then slowly descends to compress the polyolefin sponge. After the compression is completed, the pressing cylinder 16 starts and drives the upper mounting seat 17 and the upper hot pressing rod 18 to descend. The upper hot pressing rod 18 presses the open end of the packaging bag to contact with the lower hot pressing rod 14, and then the upper hot pressing rod 18 and the lower hot pressing rod 14 generate heat to perform heat-pressing and sealing on the packaging bag. After the sealing is completed, the pressing cylinder 16 drives the upper mounting seat 17 and the upper hot pressing rod 18 to reset, and the lifting cylinder 5 drives the compression assembly 4 to reset. Finally, the feeding assembly 6 starts again to send the sealed polyolefin sponge to the downstream equipment, and then continues to take over the new polyolefin sponge to be sealed.

[0024] When the lifting cylinder 5 drives the compression assembly 4 to move up and down, the compression assembly 4 will drive the synchronous gear 20 to rotate through the synchronous shaft 19. Due to the limitations of the synchronous rack 28 and the synchronous shaft 19, the synchronous gear 20 can only rotate synchronously and rise or fall the same distance, thereby ensuring that the compression assembly 4 can be lifted and lowered synchronously and cooperate with the conveying assembly to compress the polyolefin sponge, thereby ensuring the compression effect and packaging effect.

[0025] The above-described embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
