Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive strip cooling and air drying production technology, and in particular to an adhesive strip cooling and air drying device. Background Technology
[0002] In the continuous production process of plastic film, to meet the width and specifications requirements of different end products, the film usually needs to be trimmed online or offline. The waste film generated from trimming is collected, pulled, and sent to the recycling system. After melt extrusion, filtration, and other steps, it forms continuously recycled rubber strips. Before entering the pelletizing process, the rubber strips need to undergo sufficient cooling and curing and surface dehumidification treatment to ensure that they have sufficient strength, dimensional stability, and low moisture content, thereby meeting the requirements of subsequent pelletizing processes.
[0003] Currently, the industry commonly uses water cooling and air drying equipment to cool and dehumidify recycled rubber strips. Common techniques include using fans to generate ambient or low-temperature airflow to sweep the surface of the recycled rubber strips, or passing the strips through air-drying troughs with ventilation structures. However, existing air-drying systems generally suffer from uneven airflow distribution, short drying paths, and insufficient contact with the recycled rubber strips, resulting in residual water films on the surface of the recycled rubber strips or incomplete drying of the internal core layer. This not only affects the geometric regularity and stacking density of the pellets but may also cause hydrolytic degradation during subsequent melting due to residual moisture, impairing the mechanical properties and processing stability of the remanufactured films. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rubber strip cooling and drying device, which uses a guide plate to guide the airflow, prevent the airflow from diffusing prematurely, and improve the drying effect on recycled rubber strips.
[0005] A strip cooling and drying device according to an embodiment of the present invention includes: Water cooling mechanism; The air drying mechanism includes a blowing module, an air drying plate, and a guide plate. The air drying plate is located on one side of the water cooling mechanism, and multiple guides are provided on the upper side of the air drying plate. The blowing module is located on one side of the air drying plate and is used to blow airflow onto the air drying plate. The guide plate is located above the air drying plate and is located close to the water cooling mechanism.
[0006] A strip cooling and drying device according to an embodiment of the present invention has at least the following beneficial effects: The recycled rubber strips are pulled by a drive mechanism and sequentially pass through a water-cooling mechanism and a drying mechanism to complete the cooling and drying processes. The water-cooling mechanism rapidly cools the recycled rubber strips with cooling water to ensure stable physical properties. Subsequently, the drying mechanism dries the cooled recycled rubber strips, effectively removing residual surface moisture and further reducing the strip temperature to ensure the quality of subsequent processing. After water cooling, the recycled rubber strips are conveyed to the surface of the drying plate and move smoothly along the length of the drying plate under the guidance of guide components. The airflow generated by the blowing module blows towards the drying plate, with a portion of the airflow flowing along the upper surface of the drying plate, covering and flowing over the longer recycled rubber strips, thereby increasing the contact area and improving drying uniformity and efficiency. A portion of the airflow generated by the blowing module, as it flows along the length of the drying plate towards the water-cooling mechanism, passes through the gap between the guide plate and the drying plate. The guide plate plays a crucial role in guiding the airflow, effectively constraining the airflow direction, preventing premature diffusion, and ensuring that more airflow is concentrated and orderly blown towards the water-cooling mechanism from below the guide plate. This allows the longer section of recycled adhesive strip, which is output from the water-cooling mechanism and transported below the guide plate to the vicinity of the blowing module, to fully contact the directional airflow for drying, thereby significantly enhancing the overall drying effect, improving the moisture removal efficiency, and further assisting in cooling the adhesive strip.

[0008] According to an embodiment of the present invention, a strip cooling and drying device is provided with multiple guide plates, which are arranged sequentially at intervals along the length of the drying plate, and the lower surfaces of the multiple guide plates are parallel to the upper surfaces of the drying plate.
[0009] According to an embodiment of the present invention, a strip cooling and drying device is provided, wherein the drying plate is inclined relative to the horizontal plane, the end of the drying plate closer to the water cooling mechanism is the lower end, and the end of the drying plate further away from the water cooling mechanism is the higher end.
[0010] According to an embodiment of the present invention, a strip cooling and drying device includes a water cooling mechanism comprising a circulating cooling tank, wherein the lower end of the drying plate is connected to one end of the circulating cooling tank.
[0011] According to an embodiment of the present invention, a strip cooling and drying device includes a blowing module comprising a fan and a deflector hood. The deflector hood is connected to the air outlet of the fan, and the fan can blow airflow to the drying plate through the deflector hood.
[0012] According to an embodiment of the present invention, a strip cooling and drying device is provided, wherein a flow guide is disposed above a drying plate, and a fan blows downward airflow onto the drying plate through the flow guide.

[0023] Currently, after plastic extrusion equipment extrudes recycled rubber strips 400, the industry generally uses water cooling and air drying equipment to cool and dehumidify the recycled rubber strips 400. Common methods include using a fan 211 to generate ambient or low-temperature airflow to blow on the surface of the recycled rubber strips 400, or passing the rubber strip through an air drying trough with a ventilation structure. However, existing air drying systems generally suffer from uneven airflow distribution, short air drying paths, and insufficient contact with the recycled rubber strips 400, which easily leads to residual water film on the surface of the recycled rubber strips 400 or incomplete drying of the internal core layer.
[0024] Reference Figures 1 to 3 This utility model provides a strip cooling and drying device, including a water cooling mechanism 100, a drying mechanism 200 and a driving mechanism 300. The drying mechanism 200 includes a blowing module 210, a drying plate 220 and a guide plate 230. The drying plate 220 is disposed on one side of the water cooling mechanism 100, and a plurality of guide members 221 are disposed on the upper side of the drying plate 220. The blowing module 210 is disposed on one side of the drying plate 220 and is used to blow airflow onto the drying plate 220. The guide plate 230 is disposed above the drying plate 220 and is disposed close to the water cooling mechanism 100.
[0025] Specifically, the drive mechanism 300 is located on the side of the drying mechanism 200 away from the water cooling mechanism 100. The drive mechanism 300 includes a drive motor (not shown) and a traction roller (not shown). The drive motor and the traction roller are connected in transmission. The drive motor can drive the traction roller to rotate. The rotation of the traction roller can pull and drive the recycled rubber strip 400 through the water cooling mechanism 100 and the drying mechanism 200 in sequence, and then transport it to the subsequent process.
[0026] Specifically, the drying plate 220 has a long strip structure, and the recycled adhesive strip 400 is conveyed along the length of the drying plate 220, as shown in the reference. Figure 1 and Figure 2 The drying plate 220 is positioned on one side of the water-cooling mechanism 100 along the conveying direction of the recycled adhesive strip 400. Multiple guide members 221 are sequentially spaced along the conveying direction of the recycled adhesive strip 400 on the upper side of the drying plate 220. The guide members 221 support the recycled adhesive strip 400 and guide it towards the drive mechanism 300. The drying plate 220 also catches water droplets falling from the recycled adhesive strip 400 and guides the airflow from the blower module 210 along the upper surface of the drying plate 220. This allows some of the airflow from the blower module 210 to flow along the length of the drying plate 220 over a longer section of the recycled adhesive strip 400, thus allowing the airflow to contact a larger area of the recycled adhesive strip 400 for drying. The guide members 221 can be grooved rods, grooved rollers, or other devices that support and guide the movement of the recycled adhesive strip 400. These grooves are used to limit and guide the movement of the recycled adhesive strip 400.
[0027] Specifically, the recycled adhesive strip 400, after being cooled by the water cooling mechanism 100, is first conveyed to the top of the drying plate 220 near the water cooling mechanism 100, that is, the position between the guide plate 230 and the drying plate 220, and then conveyed to the position between the blower module 210 and the drying plate 220.
[0028] After extrusion, the recycled rubber strip 400 is pulled by the drive mechanism 300 and sequentially passes through the water cooling mechanism 100 and the air drying mechanism 200 to complete the cooling and drying processes. The water cooling mechanism 100 rapidly cools the recycled rubber strip 400 with cooling water to ensure its physical properties remain stable. Subsequently, the air drying mechanism 200 air dries the cooled recycled rubber strip 400, effectively removing residual moisture from the surface and further reducing the strip temperature to ensure the quality of subsequent processing. The water-cooled recycled rubber strip 400 is conveyed to the surface of the air drying plate 220 and moves smoothly along the length of the air drying plate 220 under the guidance of the guide member 221. The airflow generated by the blowing module 210 blows towards the air drying plate 220, with a portion of the airflow flowing along the upper surface of the air drying plate 220, covering and flowing over the longer recycled rubber strip 400, thereby increasing the contact area with the recycled rubber strip 400 and improving the uniformity and efficiency of air drying. A portion of the airflow generated by the blower module 210 flows along the length of the drying plate 220 towards the water-cooling mechanism 100, passing through the gap between the guide plate 230 and the drying plate 220. The guide plate 230 plays a crucial role in guiding the airflow, effectively constraining its direction, preventing premature diffusion, and ensuring that more airflow is concentrated and orderly blown towards the water-cooling mechanism 100 from below the guide plate 230. This allows the longer section of recycled adhesive strip 400, output from the water-cooling mechanism 100 and transported below the guide plate 230 to the vicinity of the blower module 210, to fully contact the directional drying airflow, significantly enhancing the overall drying effect, improving moisture removal efficiency, and further assisting in cooling the adhesive strip. This is beneficial for improving the subsequent processing quality and product consistency of the recycled adhesive strip 400.
[0029] According to some embodiments of this application, refer to Figure 1 The lower surface of the guide vane 230 is parallel to the upper surface of the drying plate 220. The parallel lower surface of the guide vane 230 and the upper surface of the drying plate 220 are conducive to better guiding the airflow generated by the blower module 210.
[0030] Furthermore, multiple guide vanes 230 are provided, arranged sequentially and at intervals along the length of the drying plate 220, with the lower surfaces of all guide vanes 230 parallel to the upper surfaces of the drying plate 220. The sequential arrangement of multiple guide vanes 230 further enhances the airflow guidance effect. Moreover, the low pressure generated by the rapidly flowing airflow between the guide vanes 230 and the drying plate 220 can draw in surrounding low-temperature dry air through the gaps between adjacent guide vanes 230, further improving the drying effect.
[0031] According to some embodiments of this application, refer to Figure 1The drying plate 220 is inclined relative to the horizontal plane, with the end of the drying plate 220 closer to the water cooling mechanism 100 being the lower end and the end of the drying plate 220 farther away from the water cooling mechanism 100 being the higher end. Water droplets dripping from the recycled adhesive strip 400 can flow along the inclined drying plate 220 to the lower end of the drying plate 220, reducing the accumulation of water droplets on the end of the drying plate 220 farther away from the water cooling mechanism 100, and reducing secondary humidification of the already dried recycled adhesive strip 400.
[0032] Furthermore, referring to Figure 1 and Figure 2 The water-cooling mechanism 100 includes a circulating cooling tank 110, with the lower end of the drying plate 220 connected to one end of the circulating cooling tank 110. Specifically, the circulating cooling tank 110 can hold cooling water and is also connected to an external cooling circulation pipeline (not shown), allowing for the replacement of the cooling water in the circulating cooling tank 110 to ensure its cooling effect. Water droplets dripping from the recycled rubber strip 400 can flow along the inclined drying plate 220 to its lower end and then flow back into the circulating cooling tank 110, reducing cooling water loss.
[0033] Furthermore, referring to Figure 1 and Figure 2 The blower module 210 includes a fan 211 and a deflector 212. The deflector 212 is connected to the air outlet of the fan 211, and the fan 211 can blow airflow to the drying plate 220 through the deflector 212. Specifically, the fan 211 is an electric fan 211, and the fan 211 is connected to the inside of the deflector 212 through an air duct 215.
[0034] It is understood that, in some other embodiments, reference is made to... Figure 1 and Figure 3 The air intake hood 212 has a crescent-shaped structure, and a crescent-shaped air outlet cavity 214 is provided inside the crescent-shaped air intake hood 212. Air outlets 213 are respectively provided at the lower ends of the front and rear sides of the crescent-shaped air intake hood 212. The air outlets 213 are connected to the air outlet cavity 214, and the air outlet cavity 214 is connected to the air supply pipe 215. The fan 211 can drive the airflow through the air supply pipe 215 and the air outlet cavity 214 in sequence, and finally blow it downwards from the air outlets 213 at the lower ends of the front and rear sides of the crescent-shaped air intake hood 212, onto the surface of the recycled rubber strip 400 located above the drying plate 220. The crescent-shaped air outlet cavity 214 can accelerate the passing airflow, increase the airflow speed, improve the air drying effect, and increase the airflow distance. The two air outlets 213 at the lower ends of the front and rear sides of the crescent-shaped drainage hood 212 can better balance the airflow in the air outlet cavity 214, and the two air outlets 213 are conducive to drying the recycled rubber strip 400 more evenly, so as to improve the drying effect.
[0035] Furthermore, referring to Figure 1 The air hood 212 is positioned above the drying plate 220, and the fan 211 can blow downward airflow onto the drying plate 220 through the air hood 212.
[0036] Furthermore, referring to Figure 1 and Figure 2 The drying plate 220 has two side panels 222 connected to its two sides along its width direction, and the side panels 222 extend upward in the vertical direction. The upwardly extending side panels 222 can block the two sides of the drying plate 220 along its width direction, further reducing the leakage of airflow blown by the blower module 210 and improving the drying effect.
[0037] According to some embodiments of this application, refer to Figure 1 and Figure 2 The air duct 212 is positioned above the end of the drying plate 220 away from the circulating cooling tank 110. Specifically, the fan 211 blows downward airflow through the air duct 212 towards the end of the drying plate 220 away from the circulating cooling tank 110. This airflow can flow through the inclined drying plate 220 into the circulating cooling tank 110, thus drying the recycled rubber strip 400 located a considerable distance above the drying plate 220.
[0038] According to some embodiments of this application, refer to Figure 1 and Figure 2 The circulating cooling tank 110 is also equipped with multiple pressing components 120. Specifically, the pressing component 120 can be a grooved rod, a grooved roller, or other device that presses down and guides the movement of the recycled rubber strip 400. These grooves are used to limit and guide the recycled rubber strip 400. Since the density of the recycled rubber strip 400 is less than that of water, it will float on the surface of the cooling water due to buoyancy after entering the cooling water, resulting in poor cooling effect. The pressing component 120 can press the recycled rubber strip 400 down into the cooling water to improve the cooling effect of the recycled rubber strip 400.
[0039] It is understood that, in some other embodiments, reference is made to... Figure 2 Multiple pressing components 120 are detachably mounted on the upper left and right sides of the circulating cooling tank 110.
[0040] Working principle: After the recycled rubber strip 400 is melted and extruded, it enters the circulating cooling tank 110 from front to back under the traction of the drive mechanism 300. The cooling water placed in the circulating cooling tank 110 cools the recycled rubber strip 400. After being cooled, the recycled rubber strip 400 is conveyed to the top of the drying plate 220. The airflow blown downward by the fan 211 through the guide hood 212 flows along the length of the drying plate 220 into the circulating cooling tank 110 under the combined action of the inclined drying plate 220, the spaced guide plates 230, and the surrounding plate 222, thus drying the recycled rubber strip 400 conveyed to the top of the drying plate 220. After being dried, the recycled rubber strip 400 is pulled backward by the drive mechanism 300 and conveyed to the subsequent process.
