Description

Technical Field

[0001] This invention relates to the field of water-soluble film packaging technology, and more particularly to a small main roller water-coating component and a water-soluble film packaging machine. Background Technology

[0002] Laundry detergent pods are a type of laundry cleaning product that uses a water-soluble film to encapsulate highly concentrated laundry detergent, forming bead-like particles. These pods are then added to the clothes to be washed, replacing laundry detergent and powder for cleaning. The sealing process of the water-soluble film uses an automatic film blister packaging machine. Existing packaging machines primarily use water-applying structures for sealing double-layer films. A water-soluble film automatic packaging machine with patent application number 201521046613.5 uses a humidity-regulating device (including a water seal structure) to humidify the water-soluble film before sealing, allowing the upper and lower films to seal at room temperature. However, the water-applying humidity regulation is difficult to adjust, making it difficult to control the amount of water applied to the film according to sealing requirements. This results in low applicability and uneven water application, leading to variations in the thickness and dissolution time of the laundry pods, reducing their effectiveness. Furthermore, the double-layer film structure has poor load-bearing capacity, making it prone to puncture and causing highly concentrated laundry detergent to leak out, resulting in low reliability. Therefore, a new water-applying structure and packaging machine are needed to meet the requirements of sealing multi-layer films. Summary of the Invention

The cylinder 102 is fixed to the extension frame 104, and its telescopic end is fixedly connected to the mounting frame 6. The top of the mounting frame 6 is fixedly connected to the slider 103. The purpose is to move the water-applying cloth 3 closer to or further away from the film material on the roller, and then control the contact area between the water-applying cloth 3 and the film material by controlling the translation distance, thereby controlling the water application time of the water-applying cloth 3 on the film material. The larger the contact area, the longer the water application time; the smaller the contact area, the shorter the water application time, thereby controlling the amount of water applied to the film material.

By rotating the vertical screw 402, the vertical screw 402 drives the lifting block 403 to move up and down along the mounting frame 6, thereby adjusting the squeezing force between the squeezing roller 401 and the water-applying drive assembly 2. The amount of water in the water-applying cloth 3 is controlled by the squeezing force between the squeezing roller 401 and the water-applying drive assembly 2, thereby controlling the amount of water applied to the water-applying cloth 3. After squeezing, the amount of water in each position of the water-applying cloth 3 is evenly distributed, ultimately achieving the effect of uniform water application and intuitive control of the amount of water applied.

One side of the intermediate film water-applying roller 23 abuts against the intermediate film material 21, and a first water-applying groove 24 is provided on its lower side.

[0038] In order to facilitate the adjustment of the distance between the extrusion roller 401 and the water-spreading drive assembly 2, in this embodiment, preferably, the mounting plate 101 is provided with a clearance groove 25, and the vertical screw 402 passes through the clearance groove 25. The purpose is to facilitate the rotation of the vertical screw 402, and then drive the extrusion roller 401 to move through the lifting block 403.

[0039] To facilitate improving the uniformity of extrusion, in this embodiment, preferably, the extrusion roller 401 is positioned directly above the driving roller 201 and the driven roller 202. The purpose is to use the extrusion roller 401, the driving roller 201, and the driven roller 202 to uniformly extrude the water-coated cloth 3, thereby ensuring that the water volume at each position of the water-coated cloth 3 is evenly distributed after extrusion, ultimately achieving a uniform water application effect.

[0040] To facilitate a direct and intuitive view of the adjustment range, in this embodiment, preferably, a first adjustment scale 26 is provided on one side of the lifting block 403.

[0042] The working principle and usage process of this invention: Please refer to [link / reference]. Figure 1The lower film roll 18 unwinds the lower film material 22. The lower film material 22 passes through the corner roller 12, the unwinding tension roller 13 and the lower film pressure roller 19 in sequence. The lower film pressure roller 19 heats up the lower film material 22 and then applies it to the main roller 11.

[0043] The upper film roll 14 unwinds the upper film material 20. The upper film material 20 passes through the corner roller 12, the unwinding tension roller 13 and the upper film pressure roller 15 in sequence. The upper film pressure roller 15 heats and preheats the upper film material 20 before applying it to the small main roller 10.

[0044] The intermediate film roll 16 unwinds the intermediate film material 21. The intermediate film material 21 passes sequentially through the corner roller 12, the unwinding tension roller 13, and the intermediate film water-applying roller 23. While rotating, the intermediate film water-applying roller 23 removes part of the water from the first water-applying trough 24 and applies water to one side of the intermediate film material 21. After being water-applied, the intermediate film material 21 passes through the sealing pressure roller 17. The sealing pressure roller 17 preheats the intermediate film material 21 and then squeezes and seals it with the upper film material 20.

[0045] The sealed middle film material 21 and upper film material 20 are rotated and conveyed to the water-applying component of the small main roller 10. After the water-applying cloth 3 of the small main roller water-applying component evenly applies water to the other side of the middle film material 21, it is sent to the middle film lower film sealing point 29 formed between the large main roller 11 and the small main roller 10, so that the middle film material 21 and the lower film material 22 are finally sealed. Finally, after subsequent processes, a three-layer film laundry pod is produced.

[0046] Please refer to Figures 2-3 The cylinder 102 drives the mounting frame 6 to move along the slide rail 105 via the slider 103, which in turn drives the water-applying drive assembly 2 and the water-applying cloth 3 to move as a whole, so that the water-applying cloth 3 moves closer to or away from the small main roller 10. By controlling the translation distance, the contact area between the water-applying cloth 3 and the middle film material 21 on the surface of the small main roller 10 is controlled, thereby controlling the water-applying time of the water-applying cloth 3 to the middle film material 21. The larger the contact area, the longer the water-applying time, and the smaller the contact area, the shorter the water-applying time. This controls the amount of water applied to the middle film material 21 to meet the sealing requirements of the middle film material 21 and the lower film material 22.

[0047] The vertical screw 402 can be rotated to drive the lifting block 403 to move up and down along the mounting frame 6, so that the squeezing roller 401, the driving roller 201, and the driven roller 202 are in a state of squeezing the water-coated cloth 3. The adjustment range can be viewed intuitively through the first adjustment scale 26. The amount of water in the water-coated cloth 3 can be controlled by the squeezing force between the squeezing roller 401, the driving roller 201, and the driven roller 202, thereby controlling the amount of water applied to the water-coated cloth 3. After squeezing, the amount of water in each position of the water-coated cloth 3 is evenly distributed, ultimately achieving the effect of uniform water application and intuitive control of the amount of water applied.

[0048] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
