A fully automatic packaging machine

Abstract

This utility model discloses a fully automated packaging machine, including a conveyor table. An I-beam frame is fixedly connected to the top of the conveyor table, and a hydraulic cylinder is fixedly installed on the I-beam frame. A pressure plate is fixedly connected to the bottom of the hydraulic cylinder, and a connecting block is fixedly installed on the top of the pressure plate. A sealing mechanism and an air-cooling mechanism are installed on the connecting block. This utility model achieves this by activating the sealing mechanism to descend and, in conjunction with a contact element, squeeze the bag opening to close it and perform heat sealing. The contact element acts as a buffer, protecting the bag opening during the heat sealing process and preventing excessive pressure. After heat sealing, the sealing mechanism separates from the bag opening, and then the air-cooling mechanism is activated to rapidly cool the heat-sealed bag opening, causing it to harden quickly and ensuring sealing stability. This achieves the advantages of the device in buffering pressure on the bag opening during the heat sealing process to prevent breakage, while also providing rapid cooling and improving the stability of the bag seal.

Description

Technical Field

[0001] The utility model relates to the technical field of compression packaging machines, in particular to a fully automatic packaging machine. Background Art

[0002] The compression packaging machine compresses loose items to reduce the space between them and their volume without changing the flatness of the items. It is suitable for compression packaging of various fluffy items such as bedding, pillows, and cushioning sponges packed in plastic bags of different thicknesses.

[0003] However, when the existing compression packaging machine heat-seals the bag opening during compression packaging, the sealing device directly squeezes the bag opening and cooperates with the support at the bottom to compress and heat-seal it. The lack of a buffer structure can easily lead to excessive extrusion force, causing the seal to break during the heat-sealing process. In addition, the bag is cooled naturally after heat sealing. Due to the expansion force inside the bag after compression, the bag opening that has not been completely cooled and hardened may burst, and the use effect needs to be improved.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1 to 4In the utility model, a fully automatic packaging machine includes a conveying platform 1, the top of the conveying platform 1 is fixedly connected with an I-shaped frame 2, the I-shaped frame 2 is fixedly installed with a hydraulic cylinder 3, the bottom end of the hydraulic cylinder 3 is fixedly connected with a pressing plate 4, the top of the pressing plate 4 is fixedly installed with a connecting block 5, a sealing mechanism 6 is installed on the connecting block 5, an air cooling mechanism 7 is fixedly installed on the connecting block 5, and a contact member 8 is installed on the conveying platform 1, and the contact member 8 is located directly below the sealing mechanism 6.

[0022] In the utility model, the conveying platform 1 is used as the main body of the device support. When in use, the quilt in a naturally expanded state pre-loaded into the packaging bag is conveyed to the left. When the quilt bag is conveyed to the bottom of the pressing plate 4, the conveying is stopped. At this time, the hydraulic cylinder 3 is started to drive the pressing plate 4 to descend, and the quilt bag is compressed to a specified thickness. At this time, the bag opening faces the right and is located below the sealing mechanism 6. Then the contact piece 8 is started to rise to the top and is flush with the conveying surface of the conveying platform 1. Then the sealing mechanism 6 is started to descend and cooperate with the contact piece 8 to squeeze the bag opening to close it, and heat seal it. Under the buffering effect of the contact piece 8, the bag opening is protected during the heat sealing process to avoid excessive pressure. After the heat sealing is completed, the sealing mechanism 6 and The bag mouth is separated, and then the air cooling mechanism 7 is started to quickly cool the heat-sealed bag mouth to make it harden quickly to ensure the sealing stability, thereby realizing that the device has the advantages of pressure buffering for the bag mouth during the heat sealing process to avoid damage, and at the same time has the advantages of rapid cooling effect and improving the sealing stability of the bag mouth. It solves the problem that when the bag mouth is heat-sealed for compression packaging in the prior art, the sealing device directly squeezes the bag mouth and cooperates with the support at the bottom to compress and heat-seal, and lacks a buffer structure, which easily leads to excessive extrusion force during the heat sealing process, causing the seal to break, and after heat sealing, it is naturally cooled. Due to the expansion force in the bag after compression, the bag mouth that has not been completely cooled and hardened may burst, and the use effect needs to be improved.

[0028] In the utility model, the first cylinder 61 is started to drive the electric heat sealer 62 to descend and contact the bag opening, and cooperates with the contact member 8 to squeeze the two sides of the bag opening to close and perform heat sealing, and the automatic operation is efficient and stable.

[0030] In the utility model, the micro air pump 71 is started to blow air to cool the sealing part by using the hose 72 and the air outlet 73, so as to increase the cooling speed and ensure the sealing stability.

When conveying the bedding bag, the contact block 83 can be adjusted to descend, so that the bedding bag can be conveyed smoothly. When sealing, the contact block 83 is adjusted to rise and cooperate with the electric heat sealer 62 to perform pressurized heat sealing, and pressure buffering is achieved through the spring 82 to protect the bag opening.
