Description

Technical Field

[0001] This application relates to the technical field of PVC modified material processing equipment, and in particular to a dewatering device for processing high-elasticity shoe sole foamed PVC modified materials. Background Technology

[0002] During the production of high-elasticity foamed PVC modified materials for shoe soles, water cooling or water bath treatment is often required for shaping. After treatment, a large amount of moisture remains on the surface of the material. If this moisture is not fully removed, it will directly affect the quality of subsequent processing, such as causing uneven foaming, air bubbles during hot pressing, and poor adhesion to other materials.

[0003] In existing technologies, common water removal methods include natural air drying, fan drying, or simple single-sided roller pressing. Natural air drying is inefficient, occupies a lot of space, and does not meet the requirements of continuous production; fan drying is energy-intensive and has limited effect on surface grooves; single-sided roller pressing can only treat moisture on one side of the material, which is difficult to meet the needs of efficient dehydration after water absorption, especially for scenarios with complex structures or requiring rapid and efficient water removal, particularly for highly elastic foamed PVC materials.

[0004] Therefore, there is an urgent need for a specialized device that can efficiently and continuously remove water from both the upper and lower surfaces of a material, and is easy to maintain. Summary of the Invention

[0005] The purpose of this application is to provide a dewatering device for processing high-elasticity shoe sole foamed PVC modified materials in order to solve the above-mentioned problems, thereby addressing the issues of low efficiency and poor effectiveness of existing dewatering methods mentioned in the background art.

[0006] This application achieves the above objectives through the following technical solutions:

[0007] A dewatering device for processing high-elasticity foamed PVC modified material for shoe soles, comprising:

[0008] The first conveyor is used to convey PVC modified materials. The first conveyor includes a first frame, a first conveyor roller, and a first conveyor belt.

[0009] The second conveyor is disposed above the first conveyor. The second conveyor includes a second frame, a second conveyor roller, and a second conveyor belt, and the second conveyor is vertically and vertically mounted.

[0010] The first absorbent belt is detachably mounted on the first conveyor belt and covers its surface;

[0011] The second absorbent belt is detachably mounted on the second conveyor belt and covers its surface;

[0012] By adjusting the distance between the second conveyor and the first conveyor, the first and second absorbent belts can cover and press against both sides of the PVC modified material to absorb its moisture.

[0013] In some embodiments, a dewatering mechanism is also included, the dewatering mechanism comprising:

[0014] A first dewatering assembly is disposed on the first conveyor and includes a first dewatering roller and a first water receiving hopper. The first dewatering roller is arranged side by side with any of the first conveyor rollers to squeeze the first water-absorbing belt. The first water receiving hopper is fixedly installed on the first frame to collect the squeezed water and its bottom is connected to a first drain pipe.

[0015] The second dewatering assembly is disposed on the second conveyor and includes a second dewatering roller and a second water receiving hopper. The second dewatering roller is arranged side by side with the second conveying roller to squeeze the second water-absorbing belt. The second water receiving hopper is fixedly installed on the second frame to collect the squeezed water, and its bottom is connected to a second drain pipe.

[0016] In some embodiments, the first squeezing roller is disposed below the first conveying roller so that the squeezed water drips into the first water receiving hopper by gravity; and / or, the second squeezing roller is disposed below the second conveying roller so that the squeezed water drips into the second water receiving hopper by gravity.

[0017] In some embodiments, the first absorbent belt and the second absorbent belt are detachably connected to the first conveyor belt and the second conveyor belt by Velcro.

[0018] In some embodiments, the surfaces of the first conveyor belt and the second conveyor belt are configured with receiving grooves, and the Velcro is received in the receiving grooves.

[0019] In some embodiments, an adjustment component is also included, which is connected to the second frame and is capable of driving the second conveyor to rise and fall to adjust the distance between it and the first conveyor.

[0020] In some embodiments, the adjustment assembly includes an electric upright, an electric push rod, and a connecting frame. The upright is fixedly mounted on a first frame, and the electric push rod is connected to a second frame via the connecting frame.

[0021] In some embodiments, a third conveyor and a drying chamber are also included. The third conveyor is disposed at the conveying end of the first conveyor and is used to receive the dehydrated PVC modified material. The drying chamber is disposed on the third conveyor and has a channel through which the PVC modified material passes, and a hot air fan is provided at the end of the channel.

[0022] In some embodiments, the first absorbent belt and the second absorbent belt are made of flexible absorbent material and are configured as sheet-like structures to surround and cover the first conveyor belt and the second conveyor belt.

[0023] Compared to existing technologies, this application utilizes two conveyors positioned at the top and bottom, along with their absorbent belts, to simultaneously envelop and absorb water from the upper and lower surfaces of PVC modified materials. This results in a large water removal area and high efficiency, making it particularly suitable for foamed materials with porous surfaces.

[0024] The absorbent tape is detachable, making it easy to replace, clean, and maintain, ensuring hygiene and absorbency for long-term use.

[0025] The integrated dewatering mechanism can continuously and automatically squeeze out and collect water, maintaining the water absorption capacity of the suction belt and enabling continuous operation.

[0026] A second, liftable conveyor is installed, and pressure is applied by adjusting the components. This allows it to adapt to materials of different thicknesses and increase the contact pressure between the absorbent belt and the material, thereby improving the absorbency.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] like Figures 1-3 As shown, a dewatering device for processing high-elasticity shoe sole foamed PVC modified material mainly includes a first conveyor, a second conveyor, an adjusting component, a dewatering mechanism, and an optional drying unit.

[0036] Specifically, the first conveyor serves as the main conveyor line, used to carry and transport the PVC modified material to be dehydrated. Its structure includes a first frame 1, multiple first conveyor rollers 2 mounted at both ends of the first frame 1, and a first conveyor belt 3 tensioned on the first conveyor rollers 2. The first conveyor belt 3 is preferably made of food-grade rubber or PU material with a smooth surface and a certain degree of friction to prevent the material from slipping.

[0037] Furthermore, a first absorbent belt 4 is detachably wrapped around the outer surface of the first conveyor belt 3. The first absorbent belt 4 is made of a flexible porous material with high absorbency and resilience, such as hydrophilic polyurethane sponge or microfiber cloth. In a preferred embodiment, the first absorbent belt 4 is made into a rectangular sheet structure of suitable length, and its two ends are joined together after wrapping around the first conveyor belt 3 by connectors, thereby completely covering the working surface of the first conveyor belt 3 in contact with the material.

[0038] In some embodiments, to enable quick and reliable assembly and disassembly of the first absorbent belt 4, multiple parallel receiving grooves 21 are formed on the surface of the first conveyor belt 3 along its width direction. The hook side (or rough side) of the Velcro 22 is fixed within each receiving groove 21. Correspondingly, the rough side (or hook side) of the Velcro 22 is fixed to the back of the first absorbent belt 4. Through the adhesion of the Velcro 22, the first absorbent belt 4 is firmly fixed to the first conveyor belt 3. Simultaneously, because the Velcro 22 is completely embedded in the receiving groove 21, its surface is flush with or slightly lower than the working surface of the first conveyor belt 3, thus avoiding any impact on the tight contact between the first absorbent belt 4 and the PVC material due to protruding connectors, and ensuring flat force distribution during squeezing.

[0039] The second conveyor is suspended directly above the first conveyor, and its basic structure is similar to that of the first conveyor, including a second frame 8, a second conveyor roller 9, and a second conveyor belt 10. In particular, the outer surface of the second conveyor belt 10 is also detachably covered with a second absorbent belt 11, the material of which and the connection method (e.g., through Velcro 22 in the receiving groove 21) are the same as those of the first absorbent belt 4.

[0040] To accommodate PVC modified materials of varying thicknesses and to apply appropriate contact pressure, the second conveyor is connected to the main frame via an adjustment assembly. Specifically, the adjustment assembly includes at least a pair of electric push rods 16. The fixed end of each electric push rod 16 is mounted on a vertical frame 15, while its telescopic end is fixedly connected to the top of the second frame 8 via a rigid connecting frame 17. The vertical frame 15 is fixed to the first frame 1 to provide support for the electric push rods 16. By controlling the extension and retraction of the electric push rods 16, the entire second conveyor can be precisely driven to rise and fall, thereby adjusting the distance between it and the first conveyor. During operation, the second absorbent belt 11, driven by the adjustment assembly, presses downwards against the top surface of the material, forming a "clamping" state with the first absorbent belt 4 below.

[0041] The dewatering mechanism is used to squeeze the saturated absorbent belt, allowing it to regenerate and restore its absorbent capacity. The dewatering mechanism consists of two parts: a first dewatering component corresponding to the first absorbent belt 4, and a second dewatering component corresponding to the second absorbent belt 11.

[0042] Specifically, the first dewatering assembly includes a first dewatering roller 5 and a first water receiving hopper 6. The first dewatering roller 5 is preferably a smooth-surfaced metal roller (such as a stainless steel roller), which is rotatably mounted on the side walls of the first water receiving hopper 6 via bearing seats. The first dewatering roller 5 is positioned adjacent to and below a first conveyor roller 2, allowing the first conveyor belt 3 and its first suction belt 4 to pass between them. When the first suction belt 4 passes this position, the first dewatering roller 5 and the first conveyor roller 2 work together to exert strong pressure, squeezing out the absorbed water. The squeezed-out water drips directly into the first water receiving hopper 6 below under gravity. The bottom of the first water receiving hopper 6 is connected to a first drain pipe 7 for concentrating and discharging the collected wastewater to an external bucket or sewage treatment system.

[0043] Similarly, the second dewatering assembly includes a second dewatering roller 12 and a second water receiving hopper 13. The second dewatering roller 12 is installed in a similar manner to the first dewatering roller 5, and it is located adjacent to and below a second conveyor roller 9 at the suspended end of the second conveyor. When the second suction belt 11 passes by, it is squeezed and dewatered, and the water is collected by the second water receiving hopper 13 and discharged through the second drain pipe 14.

[0044] In a preferred embodiment, to achieve final drying of the material, a third conveyor 18 is also provided at the discharge end of the first conveyor. The inlet end of the third conveyor 18 connects to the discharge end of the first conveyor to ensure a smooth material transition. Above the third conveyor 18, a drying chamber 19 is provided. The interior of the drying chamber 19 forms a tunnel-like channel for the material to pass through, and a hot air blower 20 is installed at its end (discharge end). The hot air generated by the hot air blower 20 blows along the channel onto the surface of the material, effectively evaporating residual moisture and ensuring that the material is completely dry.

[0045] Work process:

[0046] The wet PVC modified material is fed onto the first conveyor belt 3 from the upstream process. As the first conveyor belt 3 moves, the material is fed into the working area between the first and second conveyors. At this time, the electric push rod 16 drives the second conveyor to descend, causing the second absorbent belt 11 to press against the upper surface of the material, working together with the first absorbent belt 4 below to "sandwich" the material. During the journey, the moisture on the upper and lower surfaces of the material is rapidly absorbed.

[0047] The material that has completed the initial water absorption continues to be conveyed out by the first conveyor belt 3 and falls onto the third conveyor 18. Under the conveying of the third conveyor 18, the material slowly passes through the drying chamber 19, where it is further dried by the hot air blown out by the hot air blower 20, and finally obtains the dried finished product.

[0048] Meanwhile, the first water-absorbing belt 4 and the second water-absorbing belt 11 circulate under the drive of their respective conveyor belts. When the water-carrying part reaches the squeezing roller position, it is forcefully squeezed and dehydrated. The water is collected and discharged by the water receiving bucket, and the dehydrated water-absorbing belt returns to a dry state to continue participating in the next round of water absorption.

[0049] When the absorbent tape needs to be replaced or cleaned due to long-term use, simply peel it off from the Velcro 22; the operation is very simple.

[0050] In another embodiment, considering cost or control complexity, the adjustment component may not use the electric push rod 16, but instead a manual adjustment mechanism, such as a lead screw and nut mechanism or a rack and pinion mechanism. The operator can still adjust and lock the height of the second conveyor by turning a handwheel; although the level of automation is reduced, the basic functions are achieved.

[0051] In another embodiment, if the production environment has extremely high requirements for dryness, an auxiliary heating source such as an infrared heating tube can be added to the drying chamber 19 to work in conjunction with the hot air blower 20 to improve drying efficiency and effect.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
