Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, specifically to a vertical wet wipe packaging machine. Background Technology

[0002] Packaging machinery refers to machines capable of completing all or part of the packaging process for products and commodities. The packaging process includes main steps such as filling, wrapping, and sealing, as well as related pre- and post-packaging processes such as cleaning, stacking, cutting, and unpacking. Using machinery to package products can improve productivity, reduce labor intensity, meet the needs of large-scale production, and satisfy hygiene requirements. A packaging machine is a machine that packages products, playing a protective and aesthetic role. In the packaging of wet wipes, patches, and food, wet wipes are usually folded and then placed in packaging film. In actual production, existing wet wipe packaging machines are typically horizontal machines, which are relatively large. During the packaging process, they require heat sealing of the film, folding of the material, and cutting of the processed film (product). Because other processes are relatively quick, heat sealing to reliably form a four-side seal usually takes a long time. To ensure reliable product processing, the entire production line needs to be stopped or the production speed reduced, resulting in low product processing efficiency. Utility Model Content

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings: Depend on Figure 1 Combination Figure 2-13 As shown, a vertical wet wipe packaging machine includes a frame 1, and also includes: Film unwinding device 2, mounted on frame 1, is used for unwinding film material; The membrane material traction device 3 is installed on the frame 1 and is used for membrane material traction; Preheating device 4, located on frame 1, is used for preheating the film material after it is fed in; The heat sealing device 5 is mounted on the frame 1 and is used to heat seal the film material. The longitudinal cutting device 6 is mounted on the frame 1 and is used to longitudinally cut the heat-sealed product; The bag-cutting device 7 is mounted on the frame 1 and is used to cut the heat-sealed product horizontally. The preheating device 4, heat-sealing device 5, longitudinal cutting device 6, and bag-cutting device 7 are vertically and sequentially mounted on the frame 1. The heat-sealing device 5 is slidably engaged with the frame 1. The discharge device 8 is used to collect the product from the bag cutting device 7 and convey it out. The beneficial effects of this utility model are that a preheating device is provided to preheat the film material, facilitating heat sealing. The preheating device, heat sealing device, sliding device, and bag cutting device are arranged vertically, resulting in a small product size and simple structure. The heat sealing device slides and cooperates with the frame, eliminating the need to stop the machine for heat sealing, thus improving machine operation and production efficiency. This utility model also has the advantages of simple structure, convenient assembly, reliable operation, and long service life. Specifically, a coding device 10 is provided between the heat sealing device and the sliding device for coding. In fact, the film unwinding device, sliding device, bag cutting device, and discharge device can all be implemented using existing devices, which will not be elaborated here. In fact, the sliding device can slide relative to the frame; specifically, the sliding device can slide relative to the frame along the direction perpendicular to the heat-sealed film material (product) travel. This allows for sliding (longitudinal cutting) after packaging different products and also allows for fine-tuning of the sliding position, facilitating reliable production processing. In practice, during product manufacturing and packaging, a roll of film is unwound and then pulled out by a film traction device. This traction device adjusts the speed of the traction drive based on the tension at the detection roller, ensuring reliable film unwinding. The film is fed into the film feed roller, while the material passes through the unwinding device (see...). Figure 13 Material disassembly mechanism (see below) Figure 13 The material enters the material cutting device, is cut by the material cutting device, and is then inserted into the material feed roller by the material folding device, finally falling into the film material. The film material undergoes preliminary preheating by the preheating device, reducing the overall heat sealing time and enabling preheat sealing (pre-longitudinal and pre-transverse sealing) of a row of film material at one time to form multiple products. The heat sealing device then performs heat sealing, and it can slide relative to the frame along the direction of travel of the preheat-sealed film material (product), allowing the film material and the heat sealing device to move synchronously. This increases heat sealing time without requiring machine downtime, improving product heat sealing efficiency and thus increasing machine production speed and efficiency. After the film material is heat-sealed (enclosing the material to form a product), it can be coded by the coding device, and then the row of film material is longitudinally cut by the slitting device. Depending on the needs, two, three, four, or five products can be formed (this invention forms four products). The products are then cut from the film material by the bag-cutting device, and the feeding device grabs (absorbs) the products and places them onto the discharge device, which includes a discharge conveyor belt to transport the products out.

[0021] The heat sealing device 5 includes a heat sealing frame 51, a heat sealing plate 52, and a first heat sealing drive 53. The heat sealing plate 52 is mounted on the heat sealing frame 51, and the first heat sealing drive 53 is connected to the heat sealing frame 51 and drives the heat sealing frame 51 to reciprocate vertically relative to the frame 1. This allows the heat sealing plate to move vertically via the first heat sealing drive, making the transmission convenient and reliable.

[0022] There are two heat-sealing plates 52, and a heat-sealing channel 54 for the film material to pass through is provided between the two heat-sealing plates 52. The heat-sealing frame 51 is provided with a second heat-sealing drive 55. The two heat-sealing plates 52 have a first position for heat sealing driven by the second heat-sealing drive 55 and a second position for opening. There are multiple second heat-sealing drive 55s, and the multiple second heat-sealing drive 55s cooperate with each other to control the two heat-sealing plates to close or open. After the heat-sealing plates are attached, the film material can be heat-sealed.

[0023] The first heat-sealing drive component 53 is connected to the heat-sealing frame 51 via a lead screw 56. The heat-sealing frame 51 and the frame body 1 are slidably engaged via a slider 511 and a slide rail 11. The heat-sealing plate 52 is in its first position when the heat-sealing frame 51 moves downward toward the longitudinal cutting device. This structure makes the heat-sealing frame move smoothly, is simple in structure, and has convenient and reliable transmission.

[0024] Specifically, it also includes a third heat-sealing drive component 57, which is fixed to the frame 1 and connected to the heat-sealing frame 51 to balance the weight of the heat-sealing frame 51. Typically, the third heat-sealing drive component can be a cylinder, with its cylinder body fixed to the frame and its piston rod connected to the heat-sealing frame. The function of the third heat-sealing drive component is to balance the weight of the heat-sealing frame, thereby reducing the vertical force and facilitating the vertical movement of the first heat-sealing drive component. In practice, the first and second heat-sealing drive components can be motors.

[0025] The film material traction device 3 includes a traction drive 31, a detection element 32, a film material traction roller 33 for feeding the film material, and a detection roller 34 for feeding the film material. The traction drive 31 is connected to the film material traction roller 33 and drives the film material traction roller 33 to rotate. The detection element 32 is located at the detection roller 34 and connected to the traction drive 31 to monitor the tension of the film material at the detection roller 34 and control the movement of the traction drive 31. This allows control over the unwinding amount of the film material, facilitating film material feeding and thus subsequent processing.

[0026] This utility model also includes: The material cutting device 12 is located at the top of the frame 1 and is used to cut the material. The material folding device 13, located at the top of the frame 1, is used to insert the material into the film at the preheating device 4 and fold the material. The material cutting device and the material folding device work together with the material unwinding device to facilitate reliable material feeding.

[0027] The preheating device 4 includes a preheating frame 41, a material feeding roller 42 for feeding the material to be packaged, a pre-longitudinal sealing roller 43 for longitudinal sealing of the film, and a pre-transverse sealing roller 44 for transverse sealing of the film. A film feeding roller 45 is provided between the material feeding roller 42 and the pre-longitudinal sealing roller 43. This allows for heat sealing of the film, thereby reducing subsequent heat sealing time, reducing the heat sealing time of the product heat sealing device, reducing product volume, and improving production efficiency.

[0028] The film material feeding roller shaft 45 is connected to the preheating frame 41 via a gear 46 and a rack 47. A locking element 48 is provided at the film material feeding roller shaft 45 to limit its movement. A liquid inlet pipe 49 is provided between the material feeding roller shaft 42 and the film material feeding roller shaft 45. There are usually two film material feeding roller shafts, with film material passing between them. The distance between the two roller shafts can be adjusted by the gear and rack, allowing the product to adapt to different film materials. After adjustment (during operation), the locking element locks the film material feeding roller shaft to prevent slippage relative to the rack and preheating frame. The liquid inlet pipe is used to add liquid and maintain the humidity of wet wipes, face masks, etc.

[0029] This utility model also includes a feeding device 9, which is mounted on the frame 1. The feeding device 9 includes a feeding frame 91, a feeding drive 92, and a feeding suction nozzle 93. The feeding suction nozzle 93 is mounted on the feeding shaft 94. The feeding drive 92 is connected to the feeding shaft 94 via a connecting rod 95 and is used to drive the feeding shaft 94 to slide horizontally and rotate circumferentially. The feeding suction nozzle 93 has a first position for suction, a second position for horizontal movement and circumferential rotation driven by the feeding shaft 94, and a third position for discharging. The feeding device facilitates feeding. Specifically, during feeding, a top plate can be installed on the frame. After processing (below the bag cutting device), the product can fall between the feeding nozzle and the top plate. At this time, the feeding nozzle picks up the product, and the feeding drive unit drives the feeding plate to slide horizontally on the track through the connecting rod. At this time, the feeding shaft slides in the feeding frame. The feeding frame is provided with an arc-shaped limiting groove. After the feeding shaft slides horizontally, it is affected by the arc-shaped limiting groove to rotate circumferentially, so that the feeding nozzle turns, which is convenient, reliable and convenient, and facilitates the feeding device to receive and feed the material.

Any modification that utilizes the inventive concept will be included within the scope of protection of this utility model patent.
