Description

Technical Field

[0001] This utility model relates to the field of soaking device technology, specifically a foam production soaking device. Background Technology

[0002] Foam is an elastic material with a porous structure, made from plastics such as polyurethane, polyethylene, rubber, or other polymers through a foaming process. Its interior is filled with countless tiny pores, giving it properties such as light weight, good elasticity, sound insulation, heat insulation, and cushioning and shock absorption. It is widely used in packaging, home furnishing, automotive, electronics, medical and other fields, such as sofa filling, electronic product cushioning pads, and automotive sound insulation cotton. In foam production, especially in polymer foam materials such as polyurethane foam, soaking is one of the key processing steps. The core purpose is to eliminate residual chemical substances inside the material, stabilize its performance, and improve its quality.

[0003] However, in traditional tanks, when foam is stacked or locally compressed, the solution has difficulty penetrating into the interior, which can easily create dead zones. This results in residual chemicals not being removed from some areas, affecting product consistency. Furthermore, the solution circulation system has poor sealing, which can easily lead to chemical waste due to overflow or frequent replacement. The discharged waste liquid contains residual additives, resulting in high treatment costs.

[0004] Based on this, the present invention provides a foam production soaking device to solve the above-mentioned technical problems. Utility Model Content

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figures 1 to 4 This utility model proposes a foam production soaking device, comprising: Immerse the machine body 1; Splash-proof cover assembly 3 is disposed on the top of the soaking body 1; Feeding assembly 4 is located on one side of the soaking body 1; Discharge assembly 5 is located on the other side of the soaking machine body 1; Conveying component 2 is located on top of feeding component 4 and discharging component 5.

[0021] Furthermore, it should be noted that the upper surface of the soaking machine body 1 is provided with a soaking tank 11, and a pressure roller 12 and a pressure roller 2 14 are provided in the soaking tank 11. The two ends of the pressure roller 12 and the pressure roller 2 14 are fixedly connected to the soaking tank 11. A grooved pressure roller 13 is provided in the soaking tank 11, and the two ends of the grooved pressure roller 13 are fixedly connected to the soaking tank 11. Please see Figure 3The pressure rollers 12 and 14 are conventional pressure rollers that press the foam into the soaking liquid as it enters and leaves the soaking tank 11, preventing the foam from floating due to buoyancy and ensuring sufficient soaking at both the beginning and end points. The grooved pressure roller 13 increases the contact area with the foam to create a local pressure difference. As the foam passes through the middle of the soaking tank, it further squeezes the internal pores of the foam, allowing the liquid to penetrate deeper into the foam more easily. This solves the problem of sufficient surface soaking but insufficient internal soaking that may occur with ordinary flat rollers. The three sets of pressure rollers are distributed sequentially along the soaking tank 11 to form a continuous pressing path, ensuring that the foam is always pressed into the liquid throughout the soaking process. This greatly improves the uniformity of soaking and reduces product quality differences caused by uneven soaking.

[0022] Furthermore, it should be noted that the splash cover assembly 3 includes a splash cover 31, one side of which is rotatably connected to the soaking body 1 via a hinge. The splash cover assembly 3 includes a hydraulic rod 32, one end of which is rotatably connected to the splash cover 31, and the other end of which is fixedly connected to the soaking body 1. The splash cover assembly 3 includes a handle 33, which is fixedly connected to one side of the splash cover 31. Please see Figure 3 and Figure 4 The splash guard 31 is rotatably connected to the soaking machine body 1 via a hinge, which can stably cover the soaking tank 11, blocking liquid splashing from the source and preventing the workshop environment from being contaminated, especially when the soaking solution contains chemicals. It also reduces liquid waste. The hydraulic rod 32 can realize the automatic opening and closing of the splash guard 31. During production, it is closed by hydraulic drive to ensure a sealed splash-proof seal. When maintenance or cleaning of the soaking tank is required, the hydraulic rod is automatically raised, eliminating the need for manual labor to lift it. It is compatible with automated production lines and reduces the intensity of manual labor. The handle 33 serves as a backup operating part. In the event of a temporary failure of the hydraulic system, the splash guard can be manually opened and closed to ensure that production or maintenance is not interrupted and to improve the emergency fault tolerance of the equipment.

[0023] Furthermore, it should be noted that the upper surface of the feeding assembly 4 is provided with a feeding platform 41, and two razors 42 are provided on one side of the feeding platform 41. Please see Figure 3 The feeding platform 41 provides a flat placement and guiding platform for the foam, ensuring that the foam enters the soaking tank in a stable posture and avoiding uneven soaking caused by skewed feeding. Two razors 42 are symmetrically arranged on one side of the feeding platform, which can simultaneously trim the edges on both sides before the foam enters the soaking tank, removing burrs or excess parts and ensuring that the foam width is consistent. At the same time, the neat edges after trimming can reduce the risk of foam getting stuck between the pressure rollers, improve the smoothness of feeding, and indirectly ensure soaking efficiency.

[0024] Furthermore, it should be noted that the upper surface of the discharge assembly 5 is provided with a discharge platform 51, and two limiting plates 52 are provided on one side of the discharge platform 51. Please see Figure 3 and Figure 4 The discharge platform 51 provides support for the soaked foam, preventing deformation caused by the foam falling directly from the soaking tank. The two limiting plates 52 are symmetrically distributed and can form a guide channel along the width of the foam, limiting the lateral deviation of the foam and ensuring that the foam enters the subsequent process, such as drying and cutting, in a straight line, reducing secondary processing errors caused by deviation and improving production continuity.

[0025] Furthermore, it should be noted that the conveying assembly 2 includes a drive motor 23, one side of which is fixedly connected to the conveying roller 22, and the surface of the conveying roller 22 is provided with a protective cover 21. Please see Figure 2 The drive motor 23 provides stable power to the conveyor roller 22, realizing the automated transmission of foam from feeding to discharging, replacing manual handling, greatly improving production efficiency, and the conveying speed can be adjusted by the motor to adapt to the soaking time requirements of different foams. The conveyor roller 22 directly contacts and drives the foam to move, ensuring the stability of the conveying process and preventing the foam from wrinkling or shifting during transmission. The protective cover 21 can isolate the rotating parts of the conveyor roller 22: on the one hand, it prevents workshop dust and debris from being rolled into the conveying mechanism to avoid jamming or wear, and on the other hand, it prevents operators from accidentally touching the rotating conveyor roller, improving operational safety.

[0026] Furthermore, it should be noted that the soaking tank 11, pressure roller 12, trough-shaped pressure roller 13, pressure roller 2 14, conveyor roller 22, splash guard 31, hydraulic rod 32, and discharge platform 51 all use polytetrafluoroethylene (PTFE) coating. The use of PTFE coating provides corrosion resistance: PTFE has extremely strong resistance to most chemical solutions, acids, alkalis, and organic solvents, preventing corrosion of components such as the soaking tank 11 and pressure rollers, extending equipment lifespan, and reducing maintenance costs. It also has a low coefficient of friction: the smooth coating surface reduces friction between the foam and the pressure rollers and conveyor roller 22, preventing scratches or tears on the foam surface, especially when the foam is soft after soaking, protecting the product's appearance. Finally, it is non-stick: it prevents soaking liquid residue and foam debris from adhering to the component surfaces, reducing cleaning frequency and preventing secondary contamination of subsequent foam by residual liquid, maintaining a clean production environment.

[0027] In practical applications, the foam to be soaked is first placed on the feeding platform 41 of the feeding assembly 4. The foam is then adjusted so that its edges are aligned with the guide lines of the feeding platform, ensuring that it enters the conveying path in a flat state. The drive motor 23 of the conveying assembly 2 is then started, and the foam moves towards the soaking tank 11 with the conveying rollers 22. When it passes the razors 42 on both sides of the feeding platform 41, the razors automatically trim the edges of the foam on both sides, removing burrs or excess parts to ensure consistent width. The trimmed foam continues to be conveyed and smoothly enters the inlet of the soaking tank 11. At the point where the foam is pressed into the soaking liquid by pressure roller 12, the foam moves along the soaking tank 11 under the drive of conveyor roller 22, passing through pressure roller 12, trough-shaped pressure roller 13, and pressure roller 24 in sequence. Pressure roller 12 presses the foam into the liquid, ensuring that the starting point of soaking is in full contact with the soaking liquid. The trough-shaped pressure roller 13 increases the contact area to form a local pressure difference, squeezing the internal pores of the foam and allowing the liquid to penetrate to a deeper layer, solving the problem of uneven soaking between the surface and the interior. Pressure roller 24 presses the foam again before it leaves, ensuring that the entire soaking process is complete. During the soaking process, the foam is always pressed into the liquid, improving uniformity. During this process, the splash cover 31 of the splash cover assembly 3 is kept closed by the hydraulic rod 32, tightly covering the soaking tank 11 to prevent the soaking liquid from splashing due to the movement of the foam or the rotation of the pressure roller, while reducing liquid evaporation and waste. After soaking, the foam is discharged from the soaking tank 11 by the pressure roller 14 and conveyed to the discharge platform 51 of the discharge assembly 5. The discharge platform provides support to prevent the foam from falling and deforming. When the foam moves on the discharge platform, the limit plates 52 on both sides form a guide channel to limit its lateral deviation and ensure that it enters the subsequent process such as drying and cutting in a straight line, reducing secondary processing errors. After the last piece of foam has completely left the soaking tank 11 and passed through the discharge assembly 5, the drive motor 23 of the conveying assembly 2 is turned off to stop the conveying. The hydraulic rod 32 of the splash cover assembly 3 is activated to automatically lift the splash cover 31, exposing the soaking tank 11 for subsequent cleaning. The remaining soaking liquid in the soaking tank 11 is discharged. If replacement is required, it can be recycled according to process requirements.
