Description

Technical Field

[0001] This utility model relates to the technical field of disposable hygiene product production equipment, and in particular to a liquid pressing device for environmentally friendly wet wipes. Background Technology

[0002] With the development of good hygiene habits and the improvement of living standards, wet wipes have gradually become a necessity in people's daily lives. The main raw materials for the production of wet wipes are a carrier and wet wipe liquid. By loading the wet wipe liquid onto the carrier, and by adding pyrethroid chemical components to the carrier, the wet wipes can have a mosquito-repellent function. An extrusion device can squeeze out excess liquid from the wet wipes, thus ensuring that the water content of the wet wipes is not too high, thereby meeting production requirements.

[0003] Existing wet wipe pressing devices, such as the one disclosed in Chinese Patent Application No. 202121367593.7, specifically include a base plate. Above the base plate, from left to right, are arranged a first set of pressing rollers, a pressing structure, and a second set of pressing rollers. The first and second sets of pressing rollers are symmetrically arranged, each including a pair of pressing wheels for leveling and conveying the wet wipes. The pressing structure includes a support platform with a conical pressing groove above it. Side baffles are vertically fixed on both sides above the pressing groove, and a top plate is installed on the side baffles. A movable pressing plate is fixed on the top plate, driven by a telescopic cylinder. The width of the pressing plate is equal to that of the support platform and smaller than that of the pressing groove. A collection tank for collecting wet wipe liquid is also provided below the support platform. This device, using the pressing rollers and pressing structure in conjunction, ensures stable control of the wet wipe's moisture content while flattening it.

[0004] However, in actual production, it was found that when the liquid is squeezed by the roller set, the small contact area and high rotation speed can easily cause the stacked wet wipes to become misaligned and disordered, requiring subsequent reorganization. Moreover, less liquid is squeezed out, resulting in a relatively high moisture content in the stacked wet wipes. In the case of the telescopic cylinder driving the pressure plate and the support table to squeeze the stacked wet wipes on the support table, the rapid movement of the telescopic cylinder squeezes out the liquid from the stacked wet wipes, and some of the liquid is reabsorbed by the stacked wet wipes, making it difficult to control the moisture content of the wet wipes. The poor liquid pressing effect affects product quality. Summary of the Invention

[0005] Therefore, in view of the above problems, this utility model provides a liquid pressing device for environmentally friendly wet wipes with high liquid pressing efficiency and good liquid pressing effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A liquid pressing device for environmentally friendly wet wipes includes a frame, a primary liquid pressing mechanism, a secondary liquid pressing mechanism, a replenishment mechanism, and a belt conveyor mechanism. The primary liquid pressing mechanism is mounted on the frame and includes a drive roller, a driven roller, at least three belts, and a transmission roller assembly. The transmission roller assembly has several transmission rollers, each forming a conveying surface for conveying stacked wet wipes. The drive roller and driven roller are located on the upper side of the conveying surface and are distributed on both sides of the conveying direction of the transmission roller assembly. Each belt is wound around the drive roller and driven roller and is spaced apart along the axial direction of the drive roller. The belt conveyor mechanism is located at the output end of the primary liquid pressing mechanism. The replenishment mechanism and the secondary liquid pressing mechanism are respectively located on the upper side of the belt conveyor mechanism, and the secondary liquid pressing mechanism is located at the output end of the replenishment mechanism.

[0007] Furthermore, the driving roller and the driven roller are provided with annular grooves at corresponding positions on their circumferential surfaces, and the belt is embedded in the annular grooves. The depth of the annular grooves is greater than the thickness of the belt.

[0008] Furthermore, the liquid replenishment mechanism includes a liquid filling pipe with one end mounted on the frame via a connecting seat. The liquid filling pipe has a liquid storage chamber inside. One end of the liquid filling pipe is provided with a connection port that connects to the liquid storage chamber. The circumferential surface of the liquid filling pipe is provided with a liquid filling port that communicates with the liquid storage chamber. Each liquid filling port corresponds to an annular groove.

[0009] Furthermore, the secondary hydraulic mechanism includes a mounting base fixed on the frame, a drive cylinder located in the middle of the mounting base, guide components located on the mounting base and distributed on both sides of the drive cylinder, a top plate located on the output end of the drive cylinder and connected to the guide components, and a pressure plate located on the lower surface of the top plate.

[0010] Furthermore, the pressure plate is provided with several pressure strips arranged side by side in the transverse direction, and a drainage groove is formed between two adjacent pressure strips.

[0011] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: The liquid pressing device of this environmentally friendly wet wipe adopts a collaborative design of a two-stage liquid pressing mechanism and a liquid replenishment mechanism. The belt-roller structure of the first-stage liquid pressing mechanism achieves the initial flattening and uniform pressure of the stacked wet wipes, and can achieve continuous pressure for a long time, which is conducive to the discharge and separation of the wet wipe liquid from the wet wipe. Furthermore, the belt conveyor mechanism ensures that the wet wipe is wrinkle-free during the transfer process. At the same time, the liquid replenishment mechanism can accurately replenish the liquid before the second-stage liquid pressing, ensuring the uniformity of water content in the stacked wet wipes and avoiding the phenomenon of water content imbalance caused by the squeezing of multiple belts. Finally, the second-stage liquid pressing mechanism completes the final shaping. This structure significantly improves the liquid pressing efficiency and avoids the problem of uneven liquid distribution between wet wipe layers. Attached Figure Description

Detailed Implementation

[0013] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0014] The embodiment of this utility model is as follows: refer to Figures 1 to 4 As shown, an environmentally friendly wet wipe pressing device includes a frame, a primary pressing mechanism 1, a secondary pressing mechanism 2, a replenishing mechanism 3, and a belt conveyor 4. The primary pressing mechanism 1 is mounted on the frame and includes a drive roller 11, a driven roller 12, four belts 13, and a transmission roller assembly 14. The transmission roller assembly 14 has several transmission rollers 141, each forming a conveying surface 142 for conveying stacked wet wipes. The drive roller 11 and driven roller 12 are located on the upper side of the conveying surface 142 and are distributed on both sides of the conveying direction of the transmission roller assembly 14. Each belt 13 is wound around the drive roller 11 and driven roller 12 and is spaced apart along the axial direction of the drive roller 11. The belt conveyor 4 is located at the output end of the primary pressing mechanism 1. The replenishing mechanism 3 and the secondary pressing mechanism 2 are respectively located on the upper side of the belt conveyor 4, and the secondary pressing mechanism 2 is located at the output end of the replenishing mechanism 3.

[0015] The liquid pressing device of this eco-friendly wet wipe adopts a collaborative design of a two-stage liquid pressing mechanism and a liquid replenishment mechanism 3. The belt-roller structure of the first-stage liquid pressing mechanism 1 achieves initial flattening and uniform pressure on the stacked wet wipes, and can achieve continuous pressure for a long time, which is conducive to the discharge and separation of the wet wipe liquid. Furthermore, the belt conveyor mechanism 4 ensures that the wet wipes are wrinkle-free during the transfer process. At the same time, the liquid replenishment mechanism 3 can accurately replenish liquid before the second-stage liquid pressing to ensure the uniformity of water content in the stacked wet wipes and avoid the phenomenon of water content imbalance caused by the compression of multiple belts 13. Finally, the second-stage liquid pressing mechanism 2 completes the final shaping. This structure significantly improves the liquid pressing efficiency and avoids the problem of uneven liquid distribution between wet wipe layers.

[0016] Furthermore, the active roller 11 and the driven roller 12 are provided with corresponding annular grooves 15 on their circumferential surfaces. The belt 13 is embedded in the annular grooves 15. The depth of the annular grooves 15 is greater than the thickness of the belt 13. The depth design of the annular grooves 15 ensures that the belt 13 maintains stable alignment during operation and prevents uneven force on the wet wipes caused by belt deviation. The design that the depth of the annular grooves 15 is greater than the thickness of the belt 13 reserves space for thermal expansion and contraction of the belt, extending the service life of the belt 13. At the same time, the annular grooves 15 on the active roller 11 and the driven roller 12 can squeeze the wet wipes through the area between two adjacent annular grooves 15 on their circumferential surfaces when the wet wipes enter. Subsequently, the belt 13 squeezes the wet wipes again, which improves the uniformity of the squeezing and facilitates the discharge of wet wipe liquid.

[0017] Furthermore, the liquid replenishment mechanism 3 includes a liquid filling pipe 31 with one end mounted on the frame via a connecting seat 32. The liquid filling pipe 31 has a liquid storage chamber 33 inside. One end of the liquid filling pipe 31 is provided with a connecting port 34 that connects to the liquid storage chamber 33. The circumferential surface of the liquid filling pipe 31 is provided with a liquid filling port 35 that communicates with the liquid storage chamber 33. Each liquid filling port 35 corresponds to an annular groove 15. The corresponding design of the liquid filling pipe 31 and the annular groove 15 realizes fixed-point liquid replenishment. The liquid replenishment volume can be precisely adjusted by controlling the pressure of the liquid storage chamber 33, avoiding liquid splashing and waste caused by traditional spray-type liquid replenishment. The modular connecting seat design facilitates quick disassembly and cleaning.

[0018] In this embodiment, the secondary hydraulic mechanism 2 includes a mounting base 21 fixed on the frame, a drive cylinder 22 located in the middle of the mounting base 21, guide components 23 located on the mounting base 21 and distributed on both sides of the drive cylinder 22, a top plate 24 located on the output end of the drive cylinder 22 and connected to the guide components 23, and a pressure plate 25 located on the lower surface of the top plate 24. The combined structure of the drive cylinder 22 and the guide components 23 provides stable vertical downward pressure, and the pressure plate 25 achieves uniform force distribution through the top plate 24. Compared with traditional spring pressure... The tightening method reduces the curling defects at the edges of the wet wipes. The guide component 23 adopts a linear bearing structure to ensure the precise movement trajectory of the pressure plate 25. Several pressure strips 26 are arranged side by side along the transverse direction on the pressure plate 25. A drainage groove 27 is formed between two adjacent pressure strips 26. The side-by-side arrangement of the pressure strips 26 forms a grid-like pressing surface. The drainage groove promotes the rapid flow of squeezed liquid. The multi-pressure strip 26 structure increases the pressure per unit area by more than 3 times, which is particularly suitable for the deep dehydration of high-density fiber wet wipes. The groove structure facilitates cleaning and maintenance and prevents bacteria growth from residual liquid.
