Description

Technical Field

[0001] The utility model relates to the technical field of compression packaging of down products, in particular to a compression packaging device for down products. Background Art

[0002] Down products are made of down as filling material. After packaging, down products are large in size and inconvenient to transport. Before transportation, the air in them needs to be squeezed out to save transportation space and improve transportation efficiency. Generally, for down products that need to be compressed and packaged, the sorted down products are first placed in a pre-prepared plastic bag, and then the plastic bag containing the down products is squeezed by a compression device. Then, the bag opening is heated and sealed using heat-sealing technology to achieve the overall packaging effect of the down products.

[0003] However, the compression and heat packaging processes of the current mainstream down product compression packaging devices on the market are driven by different drive units respectively. This requires the entire packaging device to be equipped with multiple air cylinders or oil cylinders, resulting in a significant increase in the parts procurement cost of the compression packaging device, which is not conducive to the market promotion of the product. Based on this, a compression packaging device for down products is proposed. Utility Model Content

[0004] In order to solve the technical problem of compression packaging of down products, the utility model provides a compression packaging device for down products.

[0005] The utility model adopts the following technical scheme: a compression packaging device for down products, including a packaging box body and a mounting plate, the upper side of the mounting plate is fixedly connected to a plurality of lower connecting seats, the interior of each of the lower connecting seats is communicated with the mounting plate, the inner side of each of the lower connecting seats is slidably connected to a slide rod, the lower ends of the plurality of slide rods are commonly fixedly connected to the compression plate, a mounting plate driving mechanism is provided on one side of the packaging box body, the upper ends of the plurality of slide rods are provided with an elastic reset mechanism, a heat sealing mechanism is provided on one side of the mounting plate, a pressure strip mechanism is provided on the bottom side of the packaging box body, and a partition is provided inside the packaging box body.

[0007] As a further improvement of the above solution, the card block moving mechanism includes a limiting slider slidably connected to the inner side of the No. 1 card slot, and the limiting slider is fixedly connected to one end of the load-bearing rod.

[0008] As a further improvement of the above solution, the oil cylinder mechanism includes an oil cylinder fixedly connected to the inner side of the packaging box, and the output end of the oil cylinder is fixedly connected to one side of the dovetail slider.

[0009] As a further improvement of the above-mentioned scheme, the elastic reset mechanism includes an upper connecting seat fixedly connected to the upper ends of multiple sliding rods, each upper connecting seat is paired with each lower connecting seat, and a spring is arranged between the lower side of each upper connecting seat and each lower connecting seat, and each spring is sleeved on the outer side of each sliding rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model cooperates with the sliding rod, the lower connecting seat and the elastic reset mechanism. When the compression plate is driven to one side and pressed downward by the cylinder, the compression plate first squeezes the down product to achieve the effect of expelling the air in the bag. Then, when the sliding rod moves upward to the maximum position, the heat sealing unit contacts the heat sealing bottom groove for the first time, realizing the heat sealing of the bag opening of the plastic bag. The entire packaging process only requires the design of one cylinder driving unit, and there is no need to design a separate downward stamping driving unit for the heat sealing unit, which significantly reduces the parts configuration cost of the entire packaging device.

[0015] 2. The utility model cooperates with the No. 1 card slot, the No. 2 card slot, the limit slider and the load-bearing rod. When the down compression packaging operation needs to be carried out, the mounting plate together with the compression plate is pushed out from the partition by the oil cylinder and approaches the direction where the down products are placed. When the down products are compressed and packaged, the oil cylinder drives the dovetail slider to return. At this time, the mounting plate together with the compression plate can return to the partition again, reducing the occupied space and making it convenient for the staff to place the down products that need to be compressed and packaged on the work surface of the packaging box. At the same time, the partition can also serve as a storage for the mounting plate and the compression plate to prevent dust from accumulating on the surface of the compression plate.

The inner sides of the No. 1 slot 4 and the No. 2 slot 8 are simultaneously slidably connected with a load-bearing rod 7, one end of the load-bearing rod 7 is fixedly connected to the upper side of the mounting plate 15, and the other end of the load-bearing rod 7 is provided with a card block moving mechanism, and the inner side of the packaging box body 1 is provided with a cylinder mechanism.

[0028] By cooperating with the No. 1 card slot 4 and the No. 2 card slot 8, the load-bearing rod 7 can be moved horizontally and vertically. The horizontal movement can push the compression plate 16 out of or retract it from the partition 20, and the vertical movement can realize the downward pressing action of the compression plate 16 on the down product, thereby successfully realizing the discharge of air from the bag.

[0029] Please combine Figure 2 As shown, the card block moving mechanism includes a limit slider 18 that is slidably connected to the inner side of the No. 1 card slot 4. The limit slider 18 is fixedly connected to one end of the load-bearing rod 7.

[0030] Please combine Figure 3 As shown, the cylinder mechanism includes a cylinder 19 fixedly connected to the inner side of the packaging box 1, and the output end of the cylinder 19 is fixedly connected to one side of the dovetail slider 6. In this embodiment, the driving unit adopts the cylinder 19 technology route.

When the limiting slider 18 moves to the horizontal section track of the first card slot 4 When the track section is at the far left, under the push of the cylinder 19, the dovetail slider 6 continues to move. At this time, the No. 2 slot 8 cooperates with the No. 1 slot 4 in the vertical direction of the track section, and the load-bearing rod 7 moves downward, and the mounting plate 15 and the compression plate 16 move downward. When the compression plate 16 first contacts the down product, the slide bar 14 slides upward along the inner side of the lower connecting seat 17, and the spring 5 is compressed and deformed until the heat sealing unit 10 contacts the heat sealing bottom groove 13. At this time, the compression plate 16 has expelled the air in the plastic bag, and the plastic bag containing the down product is also heated and melted to achieve a compressed packaging effect for the down product.
