Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, and in particular to a vacuum pressing machine. Background Technology

[0002] Products in industries such as clothing, textiles, toys, and pet supplies are often relatively loose and difficult to shape. Therefore, after packaging, vacuuming is usually used to remove excess air from the packaging bag. This reduces the overall space occupied for easier transportation and isolates the air, increasing storage time. Currently, when vacuuming these items, the vacuum head is usually inserted directly into the bag for suction. After vacuuming, the packaging bag often has an irregular shape, making it difficult to stack and transport. Moreover, the packaging bag usually contains a lot of air, and the vacuuming speed is relatively slow. Utility Model Content

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0019] Please see Figure 1 and Figure 2 The embodiments of this utility model include:

[0020] A vacuum pressing machine includes: a worktable 1, a mounting frame 2, a vacuum pump 3, a suction nozzle drive mechanism, a vacuum suction nozzle 10, and a touch control screen 4. The mounting frame 2 is fixed to the worktable 1 surface. The mounting frame 2 is rectangular, and its projection onto the worktable 1 surface is smaller than the worktable 1 surface. The portion of the worktable surface within the mounting frame 2 is a pressing zone. A longitudinal pressing mechanism is provided above the pressing zone, supported by the mounting frame 2. Horizontal pressing mechanisms are provided on both sides of the pressing zone, also supported by the mounting frame 2. The front portion of the worktable surface extends beyond the projection area of ​​the mounting frame 2, and the extended portion of the worktable surface cooperates with... The mounting frame 2 has a bag opening pressing mechanism and a bag opening heat sealing mechanism arranged on the outer side of its front, with the heat sealing mechanism located outside the bag opening pressing mechanism. The vacuum pump 3 is installed below the workbench 1, and the vacuum nozzle 10 is connected to the vacuum pump 3. The nozzle drive mechanism is installed on the front of the workbench, and the vacuum nozzle 10 is fixed on the nozzle drive mechanism. The nozzle drive mechanism can drive the vacuum nozzle 10 to reciprocate horizontally to complete the bag opening insertion and extraction actions. The touch control screen 5 is installed on the mounting frame 2 and is electrically connected to the longitudinal pressing mechanism, the horizontal pressing mechanism, and the nozzle drive mechanism, respectively.

[0021] The longitudinal extrusion mechanism includes a longitudinal extrusion cylinder 9 and a longitudinal pressure plate 12. The longitudinal pressure plate 12 is connected to the top end of the telescopic rod of the longitudinal extrusion cylinder 9. There are two longitudinal extrusion cylinders 9, which are fixed in parallel on the top of the mounting frame 2. The two longitudinal extrusion cylinders 9 can extend and retract synchronously to drive the longitudinal pressure plate 12 to reciprocate. When the telescopic rod extends downward, it drives the longitudinal pressure plate 12 to press down to complete the extrusion action. After the extrusion is completed, the telescopic rod retracts, driving the longitudinal pressure plate 12 to reset.

[0022] The horizontal extrusion mechanism includes a horizontal fixed baffle 13, a horizontal moving baffle 14, and two horizontal push-pull cylinders 6. The cylinder bodies are symmetrically fixed on the same side of the mounting frame 2. The top ends of the telescopic rods of both horizontal push-pull cylinders 6 are simultaneously connected to the horizontal moving baffle 14. The horizontal fixed baffle 13 is installed on a platform below the other side of the mounting frame 2, located on both sides of the extrusion area, along with the horizontal moving baffle 14. The synchronous extension and retraction of the telescopic rods of the two horizontal push-pull cylinders 6 can drive the horizontal moving baffle 14 to reciprocate towards the horizontal fixed baffle 13. In actual use, the horizontal fixed baffle serves a positioning function. After the bag is placed on the extrusion area, the telescopic rods of the horizontal push-pull cylinders extend, pushing the bag towards the horizontal fixed baffle, so that the bag is positioned directly below the longitudinal pressure plate. Then, the longitudinal pressure plate is activated to press down, squeezing out excess air as much as possible.

[0023] The bag opening sealing mechanism includes a nozzle pressing cylinder 8, a nozzle pressing strip 18, and a nozzle pad 20. Both the nozzle pressing strip 18 and the nozzle pad 20 are made of rubber. Two nozzle pressing cylinders 8 are symmetrically installed on both sides of the outer front of the mounting frame 2. The telescopic rod ends of the two nozzle pressing cylinders 8 are connected by a pressing strip clamp 16. The nozzle pressing strip 18 is installed inside the pressing strip clamp 16, and the nozzle pad 20 is fixed to the platform directly below the nozzle pressing strip 18. Thus, when the vacuum nozzle 10 is working, the bag opening sealing mechanism can completely seal the bag opening through the cooperation of the nozzle pressing strip 18 and the nozzle pad 20, preventing air from entering the bag.

[0024] The heat-sealing mechanism includes a sealing cylinder 7, a heat-sealing strip 17, and a sealing heating belt 19. Two sealing cylinders 7 are symmetrically installed on both sides of the outer front of the mounting frame 2. The telescopic rod ends of the two sealing cylinders 7 are connected via a heat-sealing strip retainer 15. The heat-sealing strip 17 is installed inside the heat-sealing strip retainer 15, and the sealing heating belt 19 is fixed to the platform directly below the heat-sealing strip 17. After vacuuming and once the vacuum nozzle 10 is detached from the bag opening, the sealing cylinder 7 can directly drive the heat-sealing strip 17, closing it with the sealing heating belt 19, heating the bag opening, and achieving the sealing purpose.

[0025] The nozzle driving mechanism includes a nozzle push-pull cylinder 5 and a nozzle mounting bracket 11. The nozzle push-pull cylinder 5 is installed below the workbench 1 and located on the center line of the workbench. The nozzle mounting bracket 11 is generally L-shaped, including a long plate and a short plate that are perpendicular to each other. The vacuum nozzle 10 is fixed to the upper surface of the short plate. The long plate extends vertically downwards across the workbench and connects to the top of the telescopic rod of the nozzle push-pull cylinder 11. When the telescopic rod of the nozzle push-pull cylinder 11 extends or retracts, it can drive the nozzle mounting bracket 11 to reciprocate, thereby driving the vacuum nozzle 10 to complete the insertion and removal actions. In this way, the vacuuming and detachment actions of the vacuum nozzle from the bag opening will not affect the pressing and sealing actions.

[0026] The steps in actual use of this embodiment are as follows:

[0027] The first step is to input the corresponding compression data on the touch control screen according to the packaging requirements to determine the specifications and shape of the packaging;

[0028] The second step of the operation should be to first push the nozzle push-pull cylinder into place, then manually or robotically place the packaging bag into position, insert the bag opening into the nozzle, then pneumatically push the left cylinder horizontally in, and finally activate the downward pressing cylinder to flatten it.

[0029] The second step involves retracting the telescopic rod of the suction nozzle push-pull cylinder 5, causing the vacuum nozzle 10 to reach the suction position. Then, the product-filled packaging bag is manually or robotically placed into the squeezing area, and the bag opening is fitted onto the vacuum nozzle.

[0030] In the third step, the horizontal push-pull cylinder 6 extends its telescopic rod a corresponding distance according to the compression requirements, pushing the horizontal moving baffle 14 to push the packaging bag closer to the horizontal fixed baffle 13.

[0031] In the fourth step, the telescopic rod of the longitudinal extrusion cylinder 9 extends to the appropriate length according to the extrusion requirements, driving the longitudinal pressure plate 12 to extrude pressure on the packaging bag from above.

[0032] In the fifth step, the telescopic rod of the nozzle clamping cylinder 8 extends, causing the nozzle clamping strip 18 and the nozzle pad 20 to close tightly, pressing the vacuum nozzle 10 into the sealed bag opening. Then, the vacuum pump 3 starts working to complete the suction action.

[0033] After the sixth suction action is completed, the telescopic rod of the suction nozzle push-pull cylinder 5 is reset, so that the vacuum nozzle 10 is pulled out from the bag opening. Then the telescopic rod of the sealing cylinder 7 is extended, and the heat sealing strip 17 and the sealing heating tape 19 are closed to heat seal the bag opening. After the heat sealing is completed, the suction nozzle pressing cylinder 8, the sealing cylinder 7, the horizontal push-pull cylinder 6 and the longitudinal extrusion cylinder 9 are reset at the same time, and the packaging bag is taken out by on-site personnel or a robot.

[0034] Step 7: Repeat steps 2 through 6 until all products in the same batch are heat-sealed.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
