Description

Technical Field

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

[0002] The polyolefin sponge compression assembly, part of a polyolefin sponge pad packaging production line, is designed for efficient mattress compression. After compression and packaging, it reduces storage space and facilitates transportation. However, the current compression assembly lacks a synchronized lifting mechanism. This can lead to uneven compression force, affecting the compression effect and mattress shape, and even damaging the internal structure. This also reduces equipment operational stability, increases failure rates, and increases maintenance costs. Utility Model Content

[0003] Based on the above-mentioned problems in the prior art, the utility model provides a synchronization structure of a polyolefin sponge compression assembly, which includes a synchronization shaft, synchronization gears are fixedly installed at both ends of the synchronization shaft, a fixed bearing is installed on one side of the synchronization gear, the synchronization shaft is rotatably connected to the compression assembly through the fixed bearing, a synchronization rack is meshed with one side of the synchronization gear, and the extension direction of the synchronization rack is parallel to the compression movement direction of the compression assembly.

[0004] Among them, the synchronization structure of the polyolefin sponge compression component includes two groups of horizontal synchronization components and two groups of vertical synchronization components. The structures of the horizontal synchronization components and the vertical synchronization components are the same and both include synchronization shafts, synchronization gears, fixed bearings and synchronization racks. The horizontal synchronization components and the 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.

[0005] Among them, the synchronization structure of the polyolefin sponge compression component also includes a guide shaft and a guide slider. The guide shaft and the synchronization rack are parallel to each other. The guide slider is fixedly connected to the compression component, and the guide slider also slides with the guide shaft.

[0006] Among them, a mounting rod is fixedly installed on one side of one of the guide shafts of the synchronous structure of the polyolefin sponge compression component, and an upper travel switch and a lower travel switch are fixedly installed on the mounting rod. The upper travel switch and the lower travel switch respectively contact and cooperate with the guide slider to limit the maximum travel of the guide slider.

[0007] Among them, a counting gear is coaxially installed on one side of one of the synchronous gears in the synchronous structure of the polyolefin sponge compression component, and the counting gear is connected to the counter through a toothed belt drive.

[0008] The beneficial effects of the present invention are as follows: through the cooperation of the synchronous shaft, the synchronous gear and the synchronous rack, the synchronous lifting of the two ends of the synchronous shaft is achieved, thereby achieving the purpose of ensuring the synchronous lifting of the two ends of the compression component connected to the synchronous shaft, so that the compression component can evenly compress the polyolefin sponge pad, ensuring the compression and packaging effects.

[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] As attached Figure 1-3 The synchronous structure of a polyolefin sponge compression component shown in the figure includes two groups of horizontal synchronous components 1a and two groups of vertical synchronous components 1b. The horizontal synchronous components 1a and the vertical synchronous components 1b have the same structure and both include a synchronous shaft 2, a synchronous gear 3, a fixed bearing 4 and a synchronous rack 5. Synchronous gears 3 are fixedly installed at both ends of the synchronous shaft 2. A fixed bearing 4 is installed on each side of the synchronous shaft 2 where the two synchronous gears 3 are close to each other. The synchronous shaft 2 is rotatably connected to the upper surface of the compression component 6 through the fixed bearing 4. A synchronous rack 5 is meshed with each other on one side of each synchronous gear 3. The synchronous rack 5 is fixedly connected to the frame 7 of the packaging production line. The extension direction of the synchronous rack 5 is parallel to the compression movement direction of the compression component 6. Two groups of horizontal synchronization components 1a and two groups of vertical synchronization components 1b 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 6. The rectangle of the synchronization structure is slightly smaller than the rectangle of the compression component 6, so that the two groups of horizontal synchronization components 1a and the two groups of vertical synchronization components 1b can cover the four sides of the upper surface of the entire compression component 6 as much as possible, thereby realizing the horizontal synchronous lifting and lowering of the compression component 6.

[0015] As a preferred embodiment, the synchronization structure of the polyolefin sponge compression assembly further includes four guide shafts 8 and four guide sliders 9. The four guide shafts 8 are symmetrically mounted on both sides of the compression assembly 6, with two guide shafts 8 on each side. The guide shafts 8 and the synchronization rack 5 are parallel to each other. The guide sliders 9 are fixedly connected to the compression assembly 6. The guide sliders 9 also slide in conjunction with the guide shafts 8. The cooperation between the guide sliders 9 and the guide shafts 8 improves the lifting stability and smoothness of the compression assembly 6. A mounting rod 10 is fixedly mounted on one side of one of the guide shafts 8. An upper travel switch 11 and a lower travel switch 12 are fixedly mounted on the mounting rod 10. The upper travel switch 11 and the lower travel switch 12 are respectively in contact with the guide slider 9 to limit the maximum travel of the guide slider 9. Both travel switches are communicatively connected to the control component of the production line, and cooperate with the control component to realize automatic lifting control. A counting gear 13 is coaxially mounted on one side of one of the synchronous gears 3. The counting gear 13 is connected to a counter 15 via a toothed belt 14. The counter 15 is also connected to the control component for communication, and the rotation amount of the synchronous shaft 2 is digitized, which is convenient for the control component to calculate and control, and also convenient for the staff to check.

[0016] As attached Figure 4 As shown, the synchronization structure provided in this embodiment is installed in the packaging production line and used in conjunction with the compression assembly 6. A conveying assembly 16 for feeding and discharging is installed on the frame 7. The compression assembly 6 is installed on the frame 7 by sliding up and down through the cooperation of the guide slider 9 and the guide shaft 8. A driving cylinder 17 for driving the compression assembly 6 to move up and down is also installed on the frame 7. The synchronization rack 5 is fixedly installed on the frame 7. When the driving cylinder 17 drives the compression assembly 6 to move up and down, the compression assembly 6 will drive the synchronization gear 3 to rotate through the synchronization shaft 2. Due to the limitations of the synchronization rack 5 and the synchronization shaft 2, the synchronization gear 3 can only rotate synchronously and rise or fall the same distance, thereby ensuring that the compression assembly 6 can be raised and lowered synchronously and cooperate with the conveying assembly 16 to compress the polyolefin sponge, thereby ensuring the compression effect and packaging effect.

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.
