Description

Technical Field

[0001] The utility model relates to the technical field of vacuum packaging machines, and particularly relates to a six-sided compression type vacuum packaging machine. Background Art

[0002] A vacuum packaging machine is a device that can pump air out of the packaging of products that need to be stored in a vacuum. After pumping air, a vacuum environment will be formed between the product and the packaging bag, and the product will be deformed by the atmospheric pressure, which is convenient for the storage and transportation of the product.

[0003] When using a vacuum packaging machine, the product is placed on the vacuum machine table, and the suction nozzle of the vacuum air pump is inserted into the packaging bag outside the product. Then the vacuum air pump is started to absorb the air around the product. When the air absorption is completed, because a vacuum environment has been formed around the product, under the action of the atmospheric pressure, the product will be flattened. At this time, sealing the packaging bag can make the product temporarily in this form, which is convenient for transportation and storage.

[0004] Existing vacuum pumping devices do not have a structure for fixing and limiting the product during the pumping process. When producing products with specific shapes, sometimes it is necessary for the product to return to its original shape or be fixed in shape after being pumped to a vacuum state. Without such a pressing structure, the contraction amplitude of each part will be different during the vacuum extraction, resulting in an irregular shape of the product after vacuuming. Therefore, the existing vacuum packaging machines have the problem that they cannot shape the products after vacuum extraction. Summary of the Utility Model

[0005] The purpose of the utility model is to create a vacuum environment by setting pressing mechanisms at various angles to cooperate with the vacuum air pump, so that when performing vacuum compression, the product can shrink according to the specified shape, improving the space utilization rate of the product.

[0006] To achieve the above object, the present utility model provides the following technical solution: A six-sided compression type vacuum packaging machine, including a vacuum machine table, characterized in that: several pressing devices are arranged on the vacuum machine table, and a vacuum extraction device is also arranged on the vacuum machine table. The pressing devices are divided into a side pressing mechanism, an end pressing mechanism and a top pressing mechanism. The end pressing mechanism is opposite to the vacuum extraction device. The vacuum extraction device includes a vacuum extraction fixing plate and a vacuum extraction cylinder fixedly connected to the vacuum extraction fixing plate. The output end of the vacuum extraction cylinder is fixedly connected with a moving plate. The moving plate covers the upper part of the vacuum extraction cylinder. A vacuum air pump is fixedly connected to the moving plate. The adsorption end of the vacuum air pump extends towards the end pressing mechanism. A pressing cooperation mechanism is also arranged on the top of the vacuum machine table. The pressing cooperation mechanism includes an air nozzle blocking plate and an air nozzle cooperation cylinder fixedly connected to the top of the air nozzle blocking plate. The air nozzle blocking plate moves towards the adsorption end of the vacuum air pump.

[0007] Preferably, the pressing cooperation mechanism further includes a sealing plate. The top of the sealing plate is fixedly connected with a sealing cylinder. The sealing plate is arranged in the direction close to the vacuum air pump of the air nozzle blocking plate.

[0008] Preferably, the side pressing mechanism includes several side pressing cylinders. The output ends of the several side pressing cylinders are fixedly connected with a side pressing plate. The side pressing plate faces the side of the vacuum machine table.

[0009] Preferably, both the side pressing plate and the side pressing cylinders are symmetrically arranged on the vacuum machine table.

[0010] Preferably, the end pressing mechanism includes an end cylinder and an end pressing plate fixedly connected to the output end of the end cylinder. The end cylinder is fixedly connected to the vacuum machine table.

[0011] Preferably, the top pressing mechanism includes several top pressing cylinders and a top pressing plate fixedly connected to the output ends of the top pressing cylinders. The top pressing mechanism is located on the top surface of the vacuum machine table and is far away from the cooperation pressing mechanism and close to the end pressing mechanism.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By setting pressing mechanisms in multiple directions, the shrinkage control of the product in each direction can be carried out, which can ensure that the shape of the product after shrinkage is a fixed specific shape, and improve the space utilization rate of the product in the process of production, transportation and assembly.

[0014] 2. A seal is provided, which can seal the product while performing vacuum pumping, preventing the vacuum environment inside the product from being damaged due to untimely sealing after pumping, and further improving the quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Refer to Figures 1-4, a vacuum machine 1 is set, and the product to be evacuated is placed on the vacuum machine 1, which can evacuate the air in the product's packaging bag into a vacuum. Several pressing devices 2 are set on the vacuum machine 1. The pressing device 2 can press and extrude the packaging bag during vacuum pumping, squeezing the internal air to the outlet of the packaging bag, so as to achieve the effect of more efficiently discharging the air inside the large packaging bag. A vacuum extraction device 3 is also set on the vacuum machine 1, and the vacuum extraction device 3 can perform vacuum pumping.

[0025] Reference Figures 1-4 , the pressing device 2 is divided into a side pressing mechanism 21, an end pressing mechanism 22 and a top pressing mechanism 23. The end pressing mechanism 22 faces the vacuum extraction device 3. The side pressing mechanism 21 includes several side pressing cylinders 211. The output ends of the several side pressing cylinders 211 are fixedly connected with a side pressing plate 212. The side pressing plate 212 is pushed by the side pressing cylinder 211 to press the side of the packaging bag. The side of the side pressing plate 212 facing the vacuum machine 1, and the side pressing plate 212 and the side pressing cylinder 211 are both symmetrically arranged on the vacuum machine 1, and can press both sides of the packaging bag at the same time. The end pressing mechanism 22 includes an end cylinder 221 and an end pressing plate 222 fixedly connected to the output end of the end cylinder 221. The end cylinder 221 is fixedly connected to the vacuum machine 1, and the end pressing plate 222 is pushed by the end cylinder 221 to compress the rear end of the packaging bag. The top pressing mechanism 23 includes several top pressing cylinders 231 and a top pressing plate 232 fixedly connected to the output end of the top pressing cylinder 231, and presses the product from above.

[0026] Reference Figures 1-4 , the vacuum extraction device 3 includes a vacuum extraction fixing plate 31 and a vacuum extraction cylinder 32 fixedly connected to the vacuum extraction fixing plate 31. The output end of the vacuum extraction cylinder 32 is fixedly connected with a moving plate 33. The moving plate 33 covers the upper part of the vacuum extraction cylinder 32. A vacuum air pump 34 is fixedly connected to the moving plate 33. The adsorption end of the vacuum air pump 34 extends towards the end pressing mechanism 22. The vacuum extraction cylinder 32 drives the vacuum air pump 34 to move towards the opening direction of the packaging bag, and the air extraction end of the vacuum air pump 34 is extended into the packaging bag for vacuum pumping.

[0027] Reference Figures 1-4, a pressing and mating mechanism 11 is further provided on the top of the vacuum machine table 1. The pressing and mating mechanism 11 includes a nozzle baffle 111 and a nozzle mating cylinder 112 fixedly connected to the top of the nozzle baffle 111. The nozzle baffle 111 moves towards the adsorption end of the vacuum pump 34. The nozzle baffle 111 can press near the nozzle when the vacuum pump 34 is pumping air, thereby ensuring the pumping efficiency. The pressing and mating mechanism 11 further includes a sealing plate 12. A sealing cylinder 13 is fixedly connected to the top of the sealing plate 12. The sealing plate 12 is arranged in the direction close to the vacuum pump 34 of the nozzle baffle 111. The top end pressing mechanism 23 is located on the top surface of the vacuum machine table 1 and away from the mating pressing mechanism, in the direction close to the end pressing mechanism 22. The sealing plate 12 is close to the outermost end of the packaging bag, so as to be able to seal the outermost side of the packaging bag after the air extraction is completed, making the sealing effect and the vacuum effect better.

[0028] The working principle of this mechanism is as follows: When performing vacuum pumping, place the product packaging bag to be operated on the vacuum machine table 1. At this time, start the lateral pressing mechanism 21, the end pressing mechanism 22 and the top end pressing mechanism 23 to press the packaging bag at the same time, and then start the vacuum extraction cylinder 32 to make the nozzle of the vacuum pump 34 extend into the packaging bag, and start the vacuum pump 34 to pump air. During the air extraction process, the lateral pressing cylinder 211, the end cylinder 221 and the top end pressing cylinder 231 continuously press the packaging bag to discharge the internal gas. The nozzle baffle 111 presses the opening space near the seal under the action of the nozzle mating cylinder 112, enabling only the part where the nozzle of the vacuum pump 34 extends into the packaging bag to be open, and the internal gas can be extracted more cleanly. When the gas extraction is completed, the sealing cylinder 13 lowers the sealing plate 12, and the vacuum extraction cylinder 32 starts in the reverse direction to withdraw the nozzle of the vacuum pump 34. At this time, the sealing plate 12 seals the opening of the packaging bag, and the vacuum pumping process can be completed. At this time, the product extracted is a shaped product pressed in multiple directions by the pressing mechanism 21. The cylinder corresponding to the direction in which the contraction is required can be adjusted to obtain a product with a shape meeting the requirements, achieving the effect of improving the space utilization rate of the product after vacuum extraction.

[0029] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be understood to be within the protection scope of the present invention.
