Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging machine equipment technology, specifically a packaging machine. Background Technology
[0002] Packaging machines are mainly used to package products to protect their integrity and improve transportation efficiency. The main functions of packaging machines include automatic feeding, sealing, coding, heat shrinking, etc. According to different packaging requirements, packaging machines can be divided into various types such as food packaging machines, pharmaceutical packaging machines, and cosmetic packaging machines. At the same time, customized designs can also be made to meet the specific needs of packaging machines.
[0003] Currently, packaging machines are mainly used for packaging express parcels to form a sealed package. However, due to the different types of items being packaged, some fragile items are easily impacted by the conveyor belt surface after being guided by the sliding table, causing the items inside the express bag to break, which limits the packaging capabilities of the packaging machine. Summary of the Invention
[0004] To address the aforementioned problems, this utility model provides a packaging machine that uses an inner carrier frame within an auxiliary conveying device to receive packaged express bags. Simultaneously, the movable groove moves downwards, causing the carrier seat to fall in front of the connecting strip, slowly lowering the packaged express bags. This prevents the contents of the express bags from breaking and improves the packaging capabilities of the machine.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A packaging machine includes a packaging machine platform, a conveyor belt installed in front of the packaging machine platform, an industrial control computer installed above the packaging machine platform, an upper slide plate located below the industrial control computer, a lower slide plate connected below the upper slide plate, an auxiliary feeding device installed on the lower slide plate, and a sealing and cutting device located above the conveyor belt. The auxiliary feeding device contains a plurality of limiting clamps, each limiting clamp is equipped with a plurality of sliding shafts, and each limiting clamp has a movable groove. An inner frame is provided between the plurality of limiting clamps, and a connecting strip is located below the inner frame. The sliding shafts are mainly used to adjust the opening and closing distance of the limiting clamps, so that they can be adjusted to accommodate different packaging bag widths, making it suitable for use with packaging bags of different sizes.
[0006] Furthermore, a platform is provided within the inner frame, and a plurality of limiting rods are mounted on the surface of the platform. A platform cavity is formed within the platform, and a nesting cover is mounted on the rear surface of the platform. A connecting cap is installed inside the nesting cover. The nesting cover is mainly used to fix itself in place with the connecting cap, allowing it to be nested onto the surface of the lower platform for displacement. The connecting cap is mainly used for connecting transmission components and adapting to the movement of the platform.
[0007] Furthermore, the platform is connected to the surface of the lower slide via the nested cover, and the platform is connected to the movable groove via the limiting rod. The limiting clamp is connected to the surface of the lower slide via the sliding shaft rod. The sealing and cutting device is electrically coupled to the industrial control computer, which is electrically coupled to the conveyor belt. The auxiliary conveying device is located on one side of the conveyor belt, and the connecting strip is fixed to the side wall of the conveyor belt. The conveyor belt is mainly located in front of the auxiliary conveying device, which slowly supports the packaged bags it carries, ensuring that the bags remain flush with the conveyor belt during descent, and then fall onto the surface of the conveyor belt to complete the transfer.
[0008] Furthermore, the sliding platform contains a platform body, within which a sliding rod is installed. A connecting rod is mounted on the sliding rod, and a compression spring is nested within the sliding rod. A buffer pad is located at the end of the compression spring, and a stabilizing block is located next to the buffer pad. The surface of the platform body has multiple transverse grooves, and a displacement groove is located below each transverse groove. The compression spring primarily nests within the sliding rod and, in conjunction with the satin connecting rod, provides support. During periods of weight, the compression spring is compressed, simultaneously compressing the buffer pad, thereby enabling the connecting rod to move vertically.
[0009] Furthermore, the connecting rod is connected to the connecting cap, the connecting rod slides into the displacement groove, the transverse groove slides into the sliding shaft, the connecting rod is nested on the sliding rod, and its bottom engages with the top of the compression spring. The platform is fixed to the surface of the packaging machine. The transverse groove mainly adapts to the sliding shaft to adjust its limiting clamp width, adapting to the packaging processing of express bags according to different batches of packaging products. Beneficial effects
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] This utility model's communication limit clamp adjusts the spacing with the help of the sliding shaft rod. After adjustment, it is supported by the inner carrier frame, allowing the packaged courier bag to fall into the carrier cavity. As gravity presses down, the compression spring and the buffer block are compressed, and the carrier slowly falls between the connecting strip and the conveyor belt, so that the packaged bag is output with the conveyor belt, thereby preventing the contents of the courier bag from breaking and improving the packaging capacity of the packaging machine.

The auxiliary conveying device 7 is equipped with a plurality of limiting clamps 71, each with a plurality of sliding shaft rods 72. Each limiting clamp 71 has a movable groove 74. An inner carrier 73 is arranged between the plurality of limiting clamps 71, and a connecting strip 75 is arranged below the inner carrier 73. A platform 731 is arranged within the inner carrier 73, with a plurality of limiting rods 732 mounted on its surface.

[0021] The working principle of this utility model is explained below:
[0022] This invention connects the conveyor belt 2, industrial control computer 3, upper slide plate 4, and lower slide plate 6 to form a packaging machine platform 1. In use, the sliding shaft rod 72 installed on the limiting clamp 71 is fixed in conjunction with the inner carrier frame 73. The movable groove 74 adapts to the displacement of the inner carrier frame 73. The connecting strip 75 is connected to the inner side of the conveyor belt 2. Under the control of the industrial control computer 3 on the packaging machine body 1, air is generated to seal the express packaging bag. Then, the bag is cut by the sealing and cutting device 5. The bag falls into the platform cavity 733. The platform base 731, in conjunction with the connecting cap 735 in the nested cover 734, causes the connecting rod 64 in the slide rod 65 to move, compressing the built-in compression spring 66. With the help of the buffer pad 68 on the stabilizing block 67, the bag moves to the next position, making the side wall of the platform cavity 733 flush with the conveyor belt 2. The express packaging bag falls above the conveyor belt 2 for transmission and conveying. Then, with the help of the compression spring 66 and the buffer pad 68, the movable groove 74, in conjunction with the platform base 731, rises, and the operation is repeated.
