[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1-3 As shown, a reciprocating translational packaging device is used for packaging wet wipes, including a frame 1, on which an upper packaging knife group 10 and a lower packaging knife group 11 are installed. The upper packaging knife group and the lower packaging knife group are both installed with electric heating wires, which then perform heat-melt sealing on the packaging film of the wet wipes. The upper packaging knife group is also equipped with a cutting cylinder 21, which is connected to a cutter to cut the packaging film after heat-melt sealing.

[0023] A driving device for driving the upper packaging knife group and the lower packaging knife group is installed on the frame, and the driving device includes a driving wheel 3, the driving wheel is connected to a driving source, and the driving source is a reduction motor 2. The driving wheel is a gear, and the driving wheel is connected to a driven wheel 1 4, and the driven wheel 1 is connected to the driven wheel 2 5. The driven wheel 1 and the driven wheel 2 are both gears, and the driven wheel 1 and the driven wheel 2 have the same structure. The driven wheel 1 and the driven wheel 2 are meshed to achieve stable synchronous transmission. In this embodiment, there are two driving wheels, two driven wheels 1 and two driven wheels, which are distributed on both sides of the frame, and the two driving wheels are transmitted through a transmission shaft.

[0024] The driven wheel 1 is connected to the lower packaging knife group through the transmission component 1, and the transmission component 1 can drive the lower packaging knife group to rise and fall and translate. The driven wheel 2 is connected to the upper packaging knife group through the transmission component 2, and the transmission component 2 can drive the upper packaging knife group to rise and fall and translate. Specifically, the transmission component 1 includes a connecting arm 13 connected to the main shaft of the driven wheel 1, a hinged slider 15 at the end of the connecting arm 1, and the slider 1 is connected to the lower packaging knife group through the lower floating beam 17. A lower buffer component 19 is installed between the lower floating beam and the lower packaging knife group. The transmission component 2 includes a connecting arm 2 14 connected to the main shaft of the driven wheel 2, and a hinged slider 2 16 at the end of the connecting arm 2. Slider 2 is connected to the upper packaging knife group through the upper floating beam 18. An upper buffer assembly 20 is installed between the upper floating beam and the upper packaging knife group. Both the lower buffer assembly and the upper buffer assembly are springs to form a buffer stroke. A vertical guide rail 1 22 is connected between slider 1 and slider 2. Slider 1 and slider 2 can slide vertically along guide rail 1. Guide rail 1 is connected to a translation guide device. The translation guide device includes a slider 3 23 fixedly installed at one end of guide rail 1. A horizontal guide rail 2 24 cooperating with slider 3 is installed on the frame. Slider 3 is installed at the upper and lower ends of guide rail 1, thereby ensuring the translation stability of the upper floating beam and the lower floating beam.

[0025] During operation, the driving wheel drives the driven wheel 1 and the driven wheel 2 to rotate, and the driven wheel 1 drives the slider 1 to rotate through the connecting arm 1. Under the limiting action of the guide rail 1, the slider 1 performs a lifting movement, and at the same time, the slider 1 pushes the guide rail 1. Under the limiting action of the guide rail 2, the guide rail 1 moves horizontally, thereby causing the lower packaging knife group to move horizontally during the lifting process. Similarly, the upper packaging knife group also moves horizontally synchronously. The moving directions of the lower packaging knife group and the upper packaging knife group are opposite in the vertical direction, and the moving directions in the horizontal direction are the same. When the upper packaging knife group and the lower packaging knife group are pressed tightly, the packaging film is hot-melt sealed. Under the action of the lower buffer assembly and the upper buffer assembly, the upper packaging knife group and the lower packaging knife group move horizontally for a distance under the pressing state, thereby ensuring the hot-melt sealing time. At the end of the hot-melt sealing, the cutting cylinder is activated to cut the packaging film, and then hot-melt cutting and sealing are performed without suspending the conveying, thereby improving the packaging efficiency.

[0026] The frame is connected to a height adjustment device, which includes a base 6, on which are installed a plurality of upward support shafts 7, which are threadedly connected to the base, and a connecting plate 25 matching the support shaft is installed at the lower end of the frame, and the support shaft and the connecting plate are connected by a plane bearing, so that the support shaft can rotate relative to the connecting plate, and a synchronous rotation drive device is connected between the multiple support shafts, and the synchronous rotation drive device includes a driven synchronous pulley 8 installed on the support shaft, and also includes a driving synchronous pulley, and the driving synchronous pulley and the driven synchronous pulley are transmitted by a synchronous belt 9, and the driving synchronous pulley is connected to the handwheel 12, and the overall height of the frame can be adjusted through the height adjustment device, and the adjustment speed is fast and the stability is high.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
