Description
Technical Field
[0001] This utility model relates to the technical field of plastic strip equipment, specifically to a plastic strip dewatering device. Background Technology
[0002] When waste plastics are melted and recycled into plastic strips, the strips are cooled with water for rapid cooling. To avoid product quality issues during injection molding, the plastic particles from the strip granulation need to be kept dry. Current technology primarily uses rollers to separate the strips, while also employing fans for drying.
[0003] CN206656544U discloses a water removal device for plastic pull strips, which includes an exhaust fan, a water remover, and an air duct. The two ends of the air duct are connected to the exhaust fan and the water remover, respectively. The water remover includes a main body and a liquid storage tank. The top of the main body is open, and the top of the main body is provided with several support rods for supporting the plastic pull strips. The liquid storage tank is located on one side of the main body, and one side of the liquid storage tank is connected to the air duct. This invention allows the exhaust fan to exhaust air from the water remover, thereby removing water from the plastic pull strips.
[0004] During the dehydration process, since the plastic strip is still being pulled and moved by the granulator, the dehydration efficiency is relatively low when the existing technology only removes the moisture from the strip by exhausting air with a fan. Utility Model Content
[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a plastic strip dewatering device to solve the technical problem that the existing technology only removes moisture from the strip by exhausting air with a fan, resulting in relatively low dewatering efficiency.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:
[0007] This utility model provides a plastic strip dewatering device, comprising:
[0008] rack; and
[0009] The dewatering assembly includes a centrifugal roller, a drying fan, and a drive unit. The centrifugal roller and the drying fan are sequentially installed on the frame along the material conveying direction. The centrifugal roller can rotate around its own axis, and its side wall has a fixing position for fixing the material. When rotating, it drives the water on the surface of the material to be centrifuged. The drive unit is located on the frame and connected to the centrifugal roller, and is used to drive the centrifugal roller to rotate around its own axis.
[0010] In some embodiments, the fixing position is a plurality of separation grooves provided on the side wall of the centrifugal roller.
[0011] In some embodiments, a plurality of the separation grooves are arranged at axial intervals along the centrifugal roller, and each of the separation grooves extends circumferentially along the centrifugal roller.
[0012] In some embodiments, the centrifugal roller includes a turntable and a plurality of dewatering rollers. The turntable is rotatably mounted on the frame, and the plurality of dewatering rollers are mounted on the turntable and spaced apart along the rotation direction of the turntable. Each dewatering roller extends along the axial direction of the turntable and has the fixing position on its sidewall.
[0013] The drive unit is connected to the turntable and is used to drive the turntable to rotate.
[0014] In some embodiments, two turntables are provided, the two turntables are arranged at intervals along the axial direction of the dewatering roller, and one of the two turntables is connected to the drive unit;
[0015] The two ends of the dewatering roller are respectively connected to the two turntables.
[0016] In some embodiments, the centrifugal roller includes a connecting arm that connects two of the turntables and is located between the plurality of dewatering rollers.
[0017] In some embodiments, the dewatering roller includes a fixed arm and a dewatering seat. The fixed arm is mounted on the turntable and extends along the axial direction of the turntable. The dewatering seat is detachably mounted on the fixed arm and located outside the fixed arm for supporting materials.
[0018] In some embodiments, the end of the fixed arm is provided with a fixing screw hole, and the dehydration seat is provided with a connecting hole corresponding to the fixing screw hole;
[0019] The dewatering roller also includes a fixing bolt, which passes through the connecting hole and is screwed into the fixing screw hole.
[0020] In some embodiments, the dewatering assembly further includes a water-absorbing roller and a water-absorbing brush. The water-absorbing roller is rotatably mounted on the frame and located on the side of the centrifugal roller away from the drying fan. The water-absorbing brush is disposed on the outer wall of the water-absorbing roller.
[0021] In some embodiments, the plastic strip dewatering device further includes a water-cooling tank and a water collection tank installed on the frame. The water-cooling tank is located on the side of the centrifugal roller away from the drying fan. The water collection tank is placed below the centrifugal roller and the drying fan, and is located between the drying fan and the water-cooling tank. It is inclined downward from the end near the drying fan to the end near the water-cooling tank.
[0022] The lower end of the water collection tank is connected to the water cooling tank.
[0023] In some embodiments, the dewatering assembly further includes a baffle plate mounted on the frame and positioned above the centrifugal roller.
[0024] In some embodiments, the plastic strip dewatering device further includes a plurality of guide rollers, which are rotatably mounted on the frame and arranged sequentially at intervals along the material conveying direction, and located between the centrifugal roller and the drying fan.
[0025] Compared with existing technologies, the plastic strip dehydration device provided by this utility model arranges the drying fan and centrifugal roller sequentially along the conveying direction of the strip. Because the centrifugal roller rotates around its own axis under the drive of the drive unit, when the strip passes through the centrifugal roller after water cooling, the strip presses against the side wall of the centrifugal roller. This allows the water droplets adsorbed on the strip to be carried away by the centrifugal roller and detached from the surface of the strip, achieving initial dehydration. Furthermore, the water droplets detached from the strip are further centrifuged and thrown off by the centrifugal roller, preventing excessive water adsorption on the centrifugal roller during the dehydration process, ensuring a consistently good dehydration effect. After initial dehydration by the centrifugal roller, the strip moves to the position of the drying fan for further drying and deep dehydration.
[0026] Thus, this solution can first remove water droplets adhering to the surface of the strip via centrifugal rollers, and then remove the moisture adsorbed in the pores of the strip via drying fan, achieving multi-stage dehydration. This allows the moisture on the strip to be removed sequentially from the outside to the inside, effectively improving dehydration efficiency. Moreover, the structure is relatively simple and the cost is low. Attached Figure Description

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0034] To address the technical problem of relatively low dehydration efficiency when removing moisture from plastic strips using only a fan, this invention provides a plastic strip dehydration device. This device first removes water droplets adhering to the surface of the strip using a centrifugal roller, and then removes the moisture adsorbed in the pores of the strip using a drying fan. This multi-stage dehydration process removes moisture from the strip from the outside to the inside, effectively improving dehydration efficiency. Furthermore, the device has a relatively simple structure and low cost.
[0035] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 This is a schematic diagram of the structure of a plastic strip dewatering device in one embodiment of the present invention. The plastic strip dewatering device includes a frame 1 and a dewatering assembly. The dewatering assembly includes a centrifugal roller 2, a drying fan 3, and a drive unit 4. The centrifugal roller 2 and the drying fan 3 are sequentially installed on the frame 1 along the material conveying direction. The centrifugal roller 2 can rotate around its own axis, and its side wall has a fixing position for fixing the material. When rotating, it drives the water on the surface of the material to be centrifuged. The drive unit 4 is located on the frame 1 and connected to the centrifugal roller 2, and is used to drive the centrifugal roller 2 to rotate around its own axis.
[0036] In the plastic strip dehydration device provided by this utility model, the drying fan 3 and the centrifugal roller 2 are arranged sequentially along the conveying direction of the strip. Since the centrifugal roller 2 rotates around its own axis under the drive of the drive unit 4, when the strip passes through the centrifugal roller 2 after water cooling, the strip will press against the side wall of the centrifugal roller 2. This allows the water droplets adsorbed on the strip to be carried away by the centrifugal roller 2 and detached from the surface of the strip, achieving initial dehydration. Furthermore, the water droplets detached from the strip will be further centrifuged and thrown off by the centrifugal roller 2. The dehydration process does not cause excessive water droplets to be adsorbed on the centrifugal roller 2, ensuring that the centrifugal roller 2 always has a good dehydration effect. After initial dehydration by the centrifugal roller 2, the strip moves to the position of the drying fan 3 for further drying by the drying fan 3.
[0037] Thus, this solution can first remove water droplets adhering to the surface of the strip via centrifugal roller 2, and then remove the moisture adsorbed in the pores of the strip via drying fan 3, achieving multi-stage dehydration. This allows the moisture on the strip to be removed sequentially from the outside to the inside, effectively improving the dehydration efficiency. Moreover, the structure is relatively simple and the cost is low.
[0038] It should be noted that the configuration of the drive unit 4 is not limited, as long as it can drive the centrifugal roller 2 to rotate stably. Specifically, the drive unit 4 can be one of a permanent magnet synchronous motor, a stepper motor, or a servo motor.
[0039] In one embodiment, a plurality of separation grooves 2a are fixed to the side wall of the centrifugal roller 2. Specifically, the plurality of separation grooves 2a are arranged at intervals along the axial direction of the centrifugal roller 2, and each separation groove 2a extends circumferentially along the centrifugal roller 2.
[0040] In this embodiment, multiple separation grooves 2a are arranged at intervals along the axial direction on the side wall of the centrifugal roller 2 to accommodate multiple strips respectively, so that the centrifugal roller 2 can centrifuge and dehydrate multiple strips respectively, avoiding the accumulation of strips on the centrifugal roller 2 and reducing the dewatering effect.
[0041] In one embodiment, the centrifugal roller 2 includes a turntable 21 and a plurality of dewatering rollers 22. The turntable 21 is rotatably mounted on the frame 1, and the plurality of dewatering rollers 22 are mounted on the turntable 21 and spaced apart along the rotation direction of the turntable 21. Each dewatering roller 22 extends along the axial direction of the turntable 21 and has a fixed position on its side wall. The drive unit 4 is connected to the turntable 21 and is used to drive the turntable 21 to rotate.
[0042] In this embodiment, the centrifugal roller 2 is configured as multiple dewatering rollers 22. When the turntable 21 rotates, it drives the multiple dewatering rollers 22 to rotate synchronously. This can further and effectively prevent excessive moisture from adhering to the surface of the centrifugal roller 2, thereby improving the dewatering effect of the centrifugal roller 2. At the same time, it also allows the multiple dewatering rollers 22 to sequentially dewater the strip, achieving effective dewatering of the centrifugal roller 2.
[0043] In one embodiment, there are two turntables 21, which are arranged at intervals along the axial direction of the dewatering roller 22, and one of the two turntables 21 is connected to the drive unit 4; the two ends of the dewatering roller 22 are respectively connected to the two turntables 21.
[0044] In this embodiment, two turntables 21 are spaced apart, and the dewatering roller 22 is installed between the two turntables 21 to prevent the dewatering roller 22 from accidentally deviating. Specifically, in this solution, there are three dewatering rollers 22.
[0045] In one embodiment, the centrifugal roller 2 includes a connecting arm 23 that connects two turntables 21 and is located between a plurality of dewatering rollers 22.
[0046] In this embodiment, a connecting arm 23 is also provided between the two turntables 21 and placed between multiple dewatering rollers 22 to ensure that the two turntables 21 can rotate synchronously and stably. At the same time, the connecting arm 23 reduces the force on the dewatering rollers 22 when the two turntables 21 rotate synchronously, thus preventing the dewatering rollers 22 from deforming.
[0047] In one embodiment, please refer to Figure 3 and Figure 4 The dewatering roller 22 includes a fixed arm 221 and a dewatering seat 222. The fixed arm 221 is mounted on the turntable 21 and extends along the axial direction of the turntable 21. The dewatering seat 222 is detachably mounted on the fixed arm 221 and is located on the outside of the fixed arm 221 for supporting materials.
[0048] In this embodiment, the dewatering seat 222 is detachably connected to the fixed arm 221, so that when the surface of the dewatering seat 222 in contact with the pull bar is worn too much, it can be replaced in time to ensure the initial dewatering capacity of the centrifugal roller 2 on the pull bar.
[0049] It should be noted that the detachable connection between the dehydration seat 222 and the fixed arm 221 is not limited. In one embodiment, the dehydration seat 222 and the fixed arm 221 are detachably connected by a snap-fit. In another embodiment, the dehydration seat 222 and the fixed arm 221 are detachably connected by a pin and a pin hole.
[0050] In another embodiment, the end of the fixed arm 221 is provided with a fixing screw hole 221a, and the dewatering seat 222 is provided with a connecting hole 222a corresponding to the fixing screw hole 221a; the dewatering roller 22 also includes a fixing bolt 223, which passes through the connecting hole 222a and is screwed into the fixing screw hole 221a.
[0051] In this embodiment, the dehydration seat 222 and the fixing arm 221 are detachably connected by fixing bolts 223, resulting in a simple and reliable structure. Specifically, in this design, a fixing screw hole 221a is provided at each end of the fixing arm 221, and correspondingly, a connecting hole 222a is provided at each end of the dehydration seat 222. Meanwhile, a separation groove 2a is arranged between the two connecting holes 222a of the dehydration seat 222.
[0052] In one embodiment, the dewatering assembly further includes a water-absorbing roller 5 and a water-absorbing brush 6. The water-absorbing roller 5 is rotatably mounted on the frame 1 and located on the side of the centrifugal roller 2 away from the drying fan 3. The water-absorbing brush 6 is disposed on the outer wall of the water-absorbing roller 5.
[0053] In this embodiment, a water-absorbing brush 6 is also provided on the front side of the centrifugal roller 2, so that after the strip is water-cooled, it is first pre-dehydrated by the water-absorbing brush 6, and then dehydrated by the centrifugal roller 2 and the drying fan 3 in sequence, realizing three-stage dehydration and further improving the dehydration efficiency.
[0054] In one embodiment, the plastic strip dewatering device further includes a water-cooled tank 7 and a water collection tank 8 installed on the frame 1. The water-cooled tank 7 is located on the side of the centrifugal roller 2 away from the drying fan 3. The water collection tank 8 is placed below the centrifugal roller 2 and the drying fan 3, and is located between the drying fan 3 and the water-cooled tank 7. It is inclined downward from the end near the drying fan 3 to the end near the water-cooled tank 7. The lower end of the water collection tank 8 is connected to the water-cooled tank 7.
[0055] In this embodiment, the water collection tank 8 is simultaneously placed below the water-absorbing brush 6, the centrifugal roller 2, and the drying fan 3, and is tilted as shown above. This allows the water droplets that fall off the pull bar from the above three parts to be collected, and the collected water is returned to the water-cooling tank 7 to achieve recycling and reduce water consumption.
[0056] In one embodiment, the water removal assembly also includes a baffle plate mounted on the frame 1 and located above the centrifugal roller 2.
[0057] In this embodiment, a baffle plate is provided above the centrifugal roller 2 to prevent water droplets from splashing due to the centrifugal roller 2, and the water droplets blocked by the baffle plate can fall into the water collection tank 8 for recycling.
[0058] It should be noted that in this solution, the plastic strip dewatering device also includes multiple guide rollers 9, which are rotatably mounted on the frame 1 and spaced apart between the drying fan 3 and the water absorption roller 5.
[0059] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:
[0060] This solution employs a multi-stage dehydration system to thoroughly remove moisture adhering to the plastic strips. Specifically, a three-stage dehydration process is used. The first stage involves a water-absorbing roller 5 and its attached water-absorbing brush 6. The brush 6 not only removes moisture from the strip surface but also helps to initially separate the strips, preventing them from sticking together after washing. The second stage involves a centrifugal roller 2, which comprises three dehydrating rollers 22. These three grooved rollers are combined to form a circle, and centrifugally rotate under the drive of a motor to further remove moisture from the strip surface. A baffle plate is installed above the centrifugal roller 2 to prevent water splashing. The third stage involves a drying fan 3. The drying fan 3 uses a gentle breeze, and its crescent-shaped outlet increases the coverage area, evaporating and removing moisture from the strips.
[0061] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
