Description

Technical Field

[0001] This utility model belongs to the field of vacuum packaging technology, specifically a latex pillow packaging compressor. Background Technology

[0002] Latex pillows are made from the sap of rubber trees, which is harmless and has no side effects on the human body. The pure natural material has excellent antibacterial properties, providing a healthier and cleaner sleeping environment. During the processing of latex pillows, they need to be packaged and compressed to remove the air from the packaging bag and complete vacuum packaging for easy transportation and delivery.

[0003] Existing latex pillow packaging compressors use a flat plate pressing structure, which makes the packaging bag prone to wrinkling and deformation during the pressing and degassing process, resulting in insufficient packaging aesthetics. This can even lead to wrinkles in the latex pillow itself after packaging. Latex pillows that have been in this vacuum compression packaging for a long time are prone to irreversible deformation, affecting product quality and performance. Therefore, it is necessary to develop a latex pillow packaging compressor to address the shortcomings of existing technologies. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5As shown, this utility model provides a latex pillow packaging compressor, including a compressor frame 1. A lower pressure plate 2 is fixedly installed at the bottom of the inner cavity of the compressor frame 1, and an upper pressure plate 3 is arranged above the lower pressure plate 2. Sealed exhaust bags 4 are fixedly connected to the facing surfaces of the lower pressure plate 2 and the upper pressure plate 3. A second telescopic rod 6 and several first telescopic rods 5 are fixedly sleeved around the upper pressure plate 3. The bottom of the movable ends of the first telescopic rods 5 and the second telescopic rods 6 penetrate the upper pressure plate 3 and are fixedly connected to the top of the lower pressure plate 2. The facing surfaces of the two exhaust bags 4 are respectively connected to the second telescopic rods 6 through the lower pressure plate 2 and the upper pressure plate 3. Both the lower pressure plate 2 and the upper pressure plate 3 have an integrally formed linkage plate 7 on their right sides. Both linkage plates 7 are equipped with heat sealing components 8. The top of the compressor frame 1 is equipped with a hydraulic rod 9 and a controller 11. Due to the setting of the exhaust bladder 4, with the cooperation of the lower pressure plate 2 and the upper pressure plate 3, when the latex pillow is squeezed to exhaust air, the air can be exhausted from the center to the surroundings through the two exhaust bladders 4. This allows the air located on the upper and lower sides of the latex pillow in the packaging bag to move quickly to the surroundings, avoiding the situation where gas remains on the upper and lower sides of the latex pillow after compression, which would affect the packaging effect. At the same time, it also avoids the situation where the latex pillow wrinkles due to the lack of smooth air exhaust.

[0025] The hydraulic rod 9 has several conveying pipes 10 connected to its output end. The several conveying pipes 10 correspond one-to-one with the second telescopic rod 6 and the several first telescopic rods 5 and are interconnected. One end of the conveying pipe 10 is connected to the output end of the hydraulic rod 9, and the other end of the conveying pipe 10 is connected to the top of the second telescopic rod 6 and the several first telescopic rods 5. Due to the setting of the first telescopic rods 5, with the cooperation of the second telescopic rods 6, the upper pressure plate 3 can be driven to move up and down smoothly by the restriction of the lower pressure plate 2, so that the upper pressure plate 3 and the lower pressure plate 2 are brought closer to each other, and the air is vented and compressed through the air vent 4 between them.

[0026] The controller 11 and the hydraulic rod 9 are connected by a first connecting line 12, and the controller 11 and the heat sealing assembly 8 are connected by a second connecting line 15.

[0027] Both the lower pressure plate 2 and the upper pressure plate 3 are hollow structures. Both the lower pressure plate 2 and the upper pressure plate 3 have a connecting cavity 14 inside. Both the lower pressure plate 2 and the upper pressure plate 3 have an exhaust hole 13 on their opposite sides located on the opposite sides of the two exhaust bags 4. The opposite sides of the two exhaust bags 4 are connected to the connecting cavity 14 inside the lower pressure plate 2 and the upper pressure plate 3 respectively through the exhaust hole 13.

[0028] The second telescopic rod 6 includes a fixed tube 61 that is fixedly sleeved inside the upper pressure plate 3. The lower end of the fixed tube 61 is sealed and sleeved with an interconnected telescopic tube 62. The lower end of the telescopic tube 62 is sealed and sleeved with an interconnected connecting tube 63. The bottom of the connecting tube 63 is fixedly connected to the top of the lower pressure plate 2.

[0029] The fixed pipe 61 is fixedly connected to the side of a first solenoid valve 64, and the other end of the first solenoid valve 64 is connected to the inside of the connecting cavity 14 in the upper pressure plate 3. The bottom of the connecting pipe 63 is fixedly connected to a connecting pipe 65, and one end of the connecting pipe 65 extends to the inside of the connecting cavity 14 in the lower pressure plate 2 and is connected to a second solenoid valve 66. Due to the setting of the second telescopic rod 6, with the cooperation of the first solenoid valve 64 and the second solenoid valve 66, when the hydraulic rod 9 enters or exits hydraulic oil or air through the delivery pipe 10, the change in distance between the upper pressure plate 3 and the lower pressure plate 2 can be adapted to the expansion and contraction of the exhaust bladder 4. This not only achieves the expected technical effect, but also makes the cooperation between the equipment more reasonable.

[0030] The heat sealing assembly 8 includes a limiting groove 81 opened inside the linkage plate 7. A limiting slider 82 is slidably engaged inside the limiting groove 81. A buffer spring 83 is provided inside the limiting groove 81 to abut against the side of the limiting slider 82 away from the opposing surfaces of the lower pressure plate 2 and the upper pressure plate 3. The other end of the buffer spring 83 is abutted against the inner wall of the limiting groove 81.

[0031] A connecting seat 84 is fixedly connected to the side of the limiting slider 82 near the facing surfaces of the lower pressure plate 2 and the upper pressure plate 3. The other end of the connecting seat 84 passes through the limiting groove 81 and the linkage plate 7 and extends to the area between the facing surfaces of the lower pressure plate 2 and the upper pressure plate 3, where a hot melt strip 85 is embedded. The bottom of the hot melt strip 85 is connected to the controller 11 through the second connecting line 15. Due to the setting of the heat sealing assembly 8, with the cooperation of the limiting groove 81, the limiting slider 82 and the connecting seat 84, the elastic restoring force of the buffer spring 83 can make the two hot melt strips 85 located between the facing surfaces of the lower pressure plate 2 and the upper pressure plate 3. This ensures that after the lower pressure plate 2 and the upper pressure plate 3 press the packaging bag together, the two hot melt strips 85 can be tightly attached to the top and bottom of the packaging bag seal, while preventing the two hot melt strips 85 from breaking due to excessive resistance caused by the pushing action of the lower pressure plate 2 and the upper pressure plate 3.

[0032] Working principle and usage process of this utility model:

[0033] The latex pillow is placed inside a packaging bag and then placed between the two air bladders 4 between the lower pressure plate 2 and the upper pressure plate 3. The sealing opening is ensured to be located on the heat sealing assembly 8. The equipment is turned on so that, under the action of the controller 11, the hydraulic rod 9 draws out the hydraulic oil or air from the first telescopic rod 5 and the second telescopic rod 6 through the delivery pipe 10. Then, with the cooperation of the first solenoid valve 64 and the second solenoid valve 66, the second telescopic rod 6 and the first telescopic rod 5 are shortened at the same time, and the air pressure in the connecting cavity 14 is gradually reduced, so that the inflated air bladders 4 that are tightly attached to the upper and lower sides of the packaging bag are gradually restored.

[0034] In this way, the upper pressure plate 3 can be slowly moved down by the gradually shortening first telescopic rod 5 and second telescopic rod 6, and approach the lower pressure plate 2. The two exhaust bladders 4 between them, in conjunction with the continuously shortening distance between the upper pressure plate 3 and the lower pressure plate 2, are always in close contact with the upper and lower sides of the packaging bag, so that the gas is slowly exhausted from the lower center, so that the gas is away from the latex pillow inside the packaging bag and is discharged from the sealing port. Then, the controller 11, in conjunction with the second connecting line 15, etc., heats up the heat-melting strip 85 and heat-melts the sealing port of the packaging bag.
