Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for plastic processing, and in particular to an integrated water-scraping and cooling blower for polymer tapes, and a control method for the integrated water-scraping and cooling blower for polymer tapes. Background Technology

[0002] In the polymer extrusion tape pelletizing process, after the molten polymer is extruded through the die to form a continuous strip, it needs to undergo water cooling for initial cooling and water removal cooling in sequence, and finally enter the pelletizer to cut it into polymer particles that meet the requirements.

[0003] However, in the current dehydration and cooling stage of the conveyor belt, a large amount of water film adheres to the surface of the conveyor belt after it comes out of the water-cooling process. Due to the surface tension of water, this water film adheres tightly to the surface of the conveyor belt and is difficult to remove completely using conventional methods. The commonly used simple air-blowing dehydration method has a dehydration rate of only 50-60%, leaving a large amount of water on the surface of the conveyor belt. When these conveyor belts with residual water enter the pelletizer for cutting, water droplets will adhere to the surface of the pellets, which not only affects the appearance quality of the pellets but may also cause problems such as sticking and mold growth during subsequent storage and transportation, seriously affecting the overall quality of the product. Secondly, the temperature of the conveyor belt after water cooling is usually in the high range of 60℃-90℃, while the pelletizing process requires the conveyor belt temperature to be reduced to below 40℃ to ensure smooth pelletizing and pellet quality. However, relying solely on natural air cooling, the conveyor belt needs to travel a long path of 3-5 meters to reduce the temperature to the appropriate pelletizing temperature. This not only significantly increases the length of the production line, resulting in a large footprint for production equipment, but also prolongs the production cycle, reduces production efficiency, and increases production costs. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an integrated water-scraping and cooling blower device for polymer tape drawing. Through the synergistic effect of physical water removal by brush rollers, liquid cooling of conveyor rollers, and water removal and cooling by blowers, the water removal rate and cooling efficiency are improved, the problems of water film residue and adhesion and mold growth are solved, the particle quality is guaranteed, the production line length is shortened, and energy consumption and costs are reduced.

[0005] The present invention also proposes a control method for the above-mentioned integrated water-scraping and cooling blower device for polymer tape drawing.

[0006] The integrated water-scraping and cooling blower for polymer tape according to the present invention comprises: Base; A conveying assembly is disposed on the machine base. The conveying assembly includes a first drive motor and a conveying roller. The first drive motor is used to drive the conveying roller to rotate in order to convey the belt. A pressure-removing water assembly is disposed on the machine base. The pressure-removing water assembly includes a second drive motor and a brush roller. The second drive motor is used to drive the brush roller to rotate. The brush roller is located above the conveyor roller and is capable of removing water from the surface of the belt. A cooling and dewatering assembly is disposed on the base and located on the output side of the conveyor roller. The cooling and dewatering assembly includes a fan and an air duct located on the air outlet side of the fan. The air duct is provided with an air outlet located on the upper side of the belt and is capable of cooling the belt and / or blowing away water from the surface of the belt.

[0007] The integrated blower device for scraping and cooling polymer tape according to the present invention has at least the following beneficial effects: The conveyor rollers ensure the tape passes through the dewatering area at a uniform and stable speed, avoiding uneven dewatering caused by fluctuations in conveying speed. This solves the problem of the low dewatering rate of only 50%-60% achieved by traditional simple air blowing, effectively reducing water droplet residue on the tape surface, preventing pellet adhesion and mold growth, and ensuring the appearance quality of the pellets. Specifically, the rotating brush roller scrapes away the water film on the tape surface, using physical friction to break the surface tension of water, significantly improving dewatering efficiency. After passing through the brush roller, the dewatering rate reaches over 85%. Then, the blower, in conjunction with the air outlet of the air duct, blows air onto the tape and removes the water, increasing the total dewatering rate to 98% in conjunction with the brush roller. Furthermore, the blower, in conjunction with the air outlet of the air duct, provides air cooling to the tape, achieving dual functions of dewatering and cooling, improving production efficiency, and realizing integrated and efficient dewatering and cooling of polymer tape.

[0008] According to some embodiments of the present invention, the integrated blower device for cooling and scraping polymer tape includes a lifting seat and an adjusting stud connected to the lifting seat. The second drive motor and the brush roller are both mounted on the lifting seat. The lifting seat is vertically slidably disposed on the base. The adjusting stud is threadedly connected to the base in the vertical direction and can drive the lifting seat to rise and fall vertically, so as to abut or adjust the abutment pressure on the tape of different thicknesses.

[0010] According to some embodiments of the present invention, in a water-scraping and cooling integrated blower for polymer belts, the brush roller rotates in a direction opposite to the belt conveying direction to remove water from the surface of the belt.

[0011] According to some embodiments of the present invention, the integrated blower for cooling and scraping polymer tape has an annular groove on its outer circumferential surface. The annular groove is provided in multiple ways and is spaced apart along the axial direction of the brush roller. The tape includes multiple strips. In the radial section of the brush roller, the annular groove is arc-shaped and can abut against the circumferential surface of the strips.

[0012] According to some embodiments of the present invention, a water-cooling integrated blowing device for polymer belts is provided on the outer peripheral surface of the conveying roller. There are multiple positioning grooves, which are spaced apart along the axial direction of the conveying roller. The belt includes multiple pull strips. The positioning grooves correspond one-to-one with the positions of the pull strips and position the pull strips.

[0013] According to some embodiments of the present invention, a multi-phase conveyor roller is provided and spaced apart in the conveying direction of the conveyor belt. Each of the multi-phase conveyor rollers is connected to a coolant and a conveying pipe. The coolant circulates through the conveying pipes through the interior of the conveyor rollers to control the temperature of the conveyor rollers and to cool the conveyor belt that abuts against the surface of the conveyor rollers.

[0014] According to some embodiments of the present invention, the integrated wind-blowing device for cooling polymer tape has an air outlet slope in the air duct, and multiple air outlet holes are arranged in a dot matrix on the air outlet slope to blow air obliquely onto the tape in a direction away from the tape conveying direction.

[0015] According to some embodiments of the present invention, the integrated water-cooling blower for polymer tape is provided with a temperature detection sensor and a humidity detection sensor. The temperature detection sensor is located on the output side of the conveyor roller and is used to detect the temperature of the tape, and the humidity detection sensor is located on the output side of the output roller and is used to detect the humidity of the tape.

[0016] The control method according to the present invention is applied to the integrated water-scraping and cooling blower for polymer tape drawing as described in the present invention; the control method includes the following steps: Speed ​​control: Adjust the speed of the conveying rollers according to the speed of the pelletizer to match the speed of the pelletizer; Dehumidification control: Adjust the pressure of the brush roller against the belt and / or the rotational speed of the brush roller according to the measurement value of the humidity detection sensor; Temperature control: Adjust the temperature of the coolant, and / or the flow rate of the coolant, and / or the power of the fan according to the measurement value of the temperature detection sensor.

[0017] The control method described in this invention has at least the following beneficial effects: Through the triple coordinated adjustment of speed control, dehydration control, and temperature control, the intelligent and precise operation of the device is achieved. Specifically, the conveyor roller speed is adjusted according to the pelletizer speed to ensure synchronization between the belt conveyor and the pelletizing process, avoiding material accumulation or supply interruption; the brush roller pressure and speed are dynamically adjusted based on humidity detection values ​​to optimize the dehydration effect and reduce water film residue; and the cooling fluid parameters and fan power are adjusted based on temperature detection feedback to precisely control the belt cooling process. This control method combines mechanical adjustment with real-time monitoring, significantly improving the device's adaptability, ensuring consistency in belt dehydration and cooling effects under different operating conditions, reducing the need for manual intervention, and improving production efficiency and product quality.

[0025] In the polymer extrusion tape pelletizing process, after the molten polymer is extruded through the die to form a continuous strip, it needs to undergo water cooling for initial cooling and water removal cooling in sequence, and finally enter the pelletizer to cut it into polymer particles that meet the requirements.

[0026] However, in the current dehydration and cooling stage of the conveyor belt, a large amount of water film adheres to the surface of the conveyor belt after it comes out of the water-cooling process. Due to the surface tension of water, this water film adheres tightly to the surface of the conveyor belt and is difficult to remove completely using conventional methods. The commonly used simple air-blowing dehydration method has a dehydration rate of only 50-60%, leaving a large amount of water on the surface of the conveyor belt. When these conveyor belts with residual water enter the pelletizer for cutting, water droplets will adhere to the surface of the pellets, which not only affects the appearance quality of the pellets but may also cause problems such as sticking and mold growth during subsequent storage and transportation, seriously affecting the overall quality of the product. Secondly, the temperature of the conveyor belt after water cooling is usually in the high range of 60℃-90℃, while the pelletizing process requires the conveyor belt temperature to be reduced to below 40℃ to ensure smooth pelletizing and pellet quality. However, relying solely on natural air cooling, the conveyor belt needs to travel a long path of 3-5 meters to reduce the temperature to the appropriate pelletizing temperature. This not only significantly increases the length of the production line, resulting in a large footprint for production equipment, but also prolongs the production cycle, reduces production efficiency, and increases production costs.

[0027] Therefore, such as Figure 1 and Figure 2 The diagram shows an integrated water-scraping and cooling air-blowing device for polymer tape 400 proposed in this invention. It includes a base 100, a conveying assembly disposed on the base 100, and a pressure-removing water assembly disposed on the base 100. The conveying assembly includes a first drive motor 210 and a conveying roller 220, and the pressure-removing water assembly includes a second drive motor 310 and a brush roller 320. Specifically, the first drive motor 210 drives the conveying roller 220 to rotate, thereby conveying the tape 400. Further, the second drive motor 310 drives the brush roller 320 to rotate. The brush roller 320 is located above the conveying roller 220 and is capable of removing water from the surface of the tape 400. It is readily understood that the first drive motor and the conveying roller can be directly connected, or connected via a conveyor belt or gears; similarly, the second drive motor and the brush roller can also be directly connected, or connected via a conveyor belt or gears (not shown in the diagram). It should be noted that the conveyor roller 220 enables the belt 400 to pass through the pressure and dewatering assembly at a uniform speed, avoiding uneven dewatering caused by unstable conveying speed of the belt 400. Furthermore, the rotating scraping action of the brush roller 320 can directly act on the surface of the belt 400. Utilizing the physical properties of the brush, the water adhering to the surface of the belt 400 is effectively removed. During application, the contact between the brush roller 320 and the belt 400 can generate a certain frictional force. This frictional force helps to break the surface tension of the water film, making it easier to remove the water film that was originally tightly attached to the surface of the belt 400.

[0028] Refer to Figure 1 and Figure 2In some embodiments of the present invention, the pressure-removing water assembly includes a lifting adjustment component 330. The lifting adjustment component 330 is used to adjust the vertical height of the brush roller 320 to abut against or adjust the pressure applied to the pull belt 400 of different thicknesses. This allows for flexible adjustment of the vertical height of the brush roller 320 according to the production requirements of pull belts 400 of different thicknesses, ensuring optimal contact between the brush roller 320 and the surface of the pull belt 400. This guarantees effective removal of water from the surface of the pull belt 400 while preventing damage to the pull belt 400 due to excessive pressure, such as dents or deformation. The design of the lifting adjustment component 330 significantly improves the versatility of the device, allowing the same equipment to adapt to various specifications of pull belts 400 without frequent component replacements, thus reducing production costs. Simultaneously, by precisely adjusting the pressure, it balances water removal efficiency with the integrity of the pull belt 400, making it particularly suitable for the production of high-value-added polymer pull belts 400 where strict surface quality requirements are necessary. Specifically, in some embodiments of the present invention, the lifting adjustment component 330 includes a lifting seat 331 and an adjusting stud 332 connected to the lifting seat 331. The second drive motor 310 and the brush roller 320 are both mounted on the lifting seat 331. The lifting seat 331 is vertically slidably disposed on the base 100. The adjusting stud 332 is threadedly connected to the base 100 in the vertical direction and can drive the lifting seat 331 to rise and fall vertically. This utilizes the self-locking characteristic of the thread to ensure the stable position of the brush roller 320 after height adjustment, preventing height deviation due to vibration or tension changes in the belt 400 during equipment operation, thereby maintaining the stability and consistency of the dewatering process. It is understood that the vertical sliding engagement of the lifting seat 331 with threaded adjustment is simple in structure, highly reliable, has low maintenance costs, and is less prone to failure due to mechanical fatigue over long-term use. For example, the lifting seat and the base can achieve vertical sliding engagement through vertically arranged guide sleeves and guide posts (not shown in the figure). For example, the outer sidewall of the lifting seat 331 and the inner sidewall of the base 100 slide against each other. Furthermore, in some embodiments of the present invention, an operating handle 3321 is provided on the top of the adjusting stud 332. The operating handle 3321 is fixedly connected to the adjusting stud 332 and is used to drive the adjusting screw to rotate. This allows operators to directly perform manual tightening without the need for wrenches or other additional tools, significantly reducing the technical threshold for operators and the adjustment time. Moreover, the fixed connection between the operating handle 3321 and the adjusting stud 332 ensures direct transmission of the adjusting force, preventing slippage or loosening, making the height adjustment of the brush roller 320 more precise and convenient. Especially when different specifications of the pull belt 400 need to be quickly switched during production, it can significantly shorten changeover time and improve overall production efficiency.

[0029] Understandably, the first drive motor 210 can drive the conveyor roller 220 to rotate clockwise or counterclockwise, and the second drive motor 310 can drive the brush roller 320 to rotate clockwise or counterclockwise. To enhance the water removal effect of the brush roller 320 on the belt 400 while it is being conveyed by the conveyor roller 220, in some embodiments of the present invention, the brush roller 320 rotates in a direction opposite to the conveying direction of the belt 400 to remove water from the surface of the belt 400. For example, the conveyor roller 220 rotates counterclockwise below the belt 400 to convey the belt 400 forward, while the brush roller 320 rotates counterclockwise above the belt 400 to scrape the water on the belt 400 backward. Thus, the two generate opposing forces. This reverse friction can not only more efficiently break the surface tension of the water film, but also actively peel off stubborn water droplets adhering to the surface of the belt 400. Especially for thin water films that are tightly adhered due to surface tension, the reverse scraping effect is better than the same-direction rotation, and the water removal rate can be greatly improved. At the same time, the shearing effect formed by the reverse rotation direction and the conveying direction of the belt 400 helps to reduce the residual accumulation of water film on the surface of the belt 400, so that the water adhering to the belt 400 can be removed better.

[0030] Optionally, the brush roller 320 and the conveyor roller 220 rotate at different speeds. For example, when rotating in the same direction or in opposite directions, the speed difference between the brush roller 320 and the conveyor roller 220 is different. This speed difference creates a dynamic friction environment, and the belt 400 is simultaneously subjected to the forward thrust of the conveyor roller 220 and the reverse and / or differential frictional force of the brush roller 320 during conveying. This combined motion further disrupts the continuity of the water film. In some differential speed designs, the speed ratio can be flexibly adjusted according to the material, thickness, and water film state of the belt 400. This avoids the problem of insufficient friction leading to incomplete water removal or excessive friction damaging the surface of the belt 400 that may occur at a single speed. While ensuring efficient water removal, it also protects the surface of the belt 400, making it particularly suitable for high-viscosity or easily scratched polymer belts 400.

[0031] Refer to Figure 2In some embodiments of the present invention, the outer peripheral surface of the brush roller 320 is provided with an annular groove. Multiple annular grooves are spaced apart along the axial direction of the brush roller 320 (not shown in the figure). The pull belt 400 includes multiple pull strips 410. In the radial cross-section of the brush roller 320, the annular groove is arc-shaped and can abut against the peripheral surface of the pull strips 410. For example, for a pull belt 400 with a thickness of 0.5 mm to 3 mm, the diameter of the arc corresponding to the annular groove is 0.5 mm, which can completely fit half a circle of a 0.5 mm pull belt 400, and also fit a small half circle of a 3 mm pull belt 400. This significantly improves the water removal effect on the edges of the pull belt 400, solving the problem of water accumulation at the edges in traditional devices. By forming a close contact between the arc-shaped groove surface and the circumference of the pull strip 410, the effective contact area between the brush roller 320 and the pull strip 410 is increased, thereby improving the local water removal efficiency. More importantly, compared with flat squeegee treatment, the arc-shaped squeegee treatment can remove water from a larger angle surface of the pull strip 410, improving the water removal efficiency. Furthermore, in some embodiments of the present invention, the outer circumference of the conveyor roller 220 is provided with positioning grooves 2201. There are multiple positioning grooves 2201, which are spaced apart along the axial direction of the conveyor roller 220. The pull belt 400 includes multiple pull strips 410, and the positions of the positioning grooves 2201 correspond one-to-one with the pull strips 410, positioning the pull strips 410. Physical limiting ensures that the pull belt 400 maintains stable positional accuracy during high-speed conveying, preventing the pull bar 410 from shifting or misaligning due to vibration or tension fluctuations. Furthermore, the design of the annular groove on the brush roller 320 further enhances this, ensuring precise positioning of the pull bar 410 during conveying and preventing it from failing to engage with the annular groove, thus avoiding a reduction in the water removal efficiency of the brush roller 320. Simultaneously, this accurately positioned conveying method provides regular feeding conditions for the subsequent pelletizing process, indirectly guaranteeing the uniformity and consistency of pellet cutting quality.

[0032] Refer to Figure 1In some embodiments of the present invention, the conveyor roller 220 is connected to a liquid cooling component. The liquid cooling component is used to control the temperature of the conveyor roller 220 to cool the belt 400 that is in contact with the surface of the conveyor roller 220. In actual use, the heat generated when the high-temperature belt 400 (60℃-90℃) comes into contact with the conveyor roller 220 can be quickly conducted away, thereby achieving active cooling of the belt 400. This solves the problem of long paths and long time consumption when relying solely on natural air cooling. It can reduce the temperature of the belt 400 to a suitable temperature below 40℃ for pelletizing within a shorter conveying distance, significantly shortening the production line length and reducing the equipment footprint. At the same time, it avoids problems such as pellet sticking and mold growth caused by excessively high belt 400 temperatures, improving product quality and production efficiency. Specifically, the liquid cooling component includes a coolant 2211 and a conveying pipe 222. The coolant 2211 circulates through the conveying pipe 222 through the interior of the conveyor roller 220, achieving continuous and efficient heat transfer. The coolant 2211 and pump are housed in a cooling tank. The coolant 2211 is forced to circulate via a pump-driven system, ensuring uniform surface temperature of the conveyor roller 220 and preventing localized overheating or undercooling. This guarantees consistent cooling across all areas of the belt 400. Furthermore, the circulation system of the conveyor pipe 222 can be connected to an external temperature control device to dynamically adjust the coolant 2211 temperature based on the initial temperature of the belt 400. This further enhances the precision of temperature control, providing a stable low-temperature input for the pelletizing process and fundamentally ensuring the reliability of pellet quality. For example, the coolant 2211 temperature can be controlled within the range of 8℃-25℃ via the cooling machine control module, thereby rapidly cooling the belt 400 to the required temperature.

[0033] Reference Figure 3In some embodiments of the present invention, a cooling and dewatering assembly is also provided on the output side of the conveyor roller 220 of the base 100. This assembly includes a fan and an air duct 510 located on the fan's outlet side. The air duct 510 has an air outlet 5101 located above the belt 400 and is capable of cooling the belt 400 and / or blowing away water from its surface. In actual use, the dewatering rate after passing through the brush roller 320 reaches over 85%. Then, the fan, in conjunction with the air outlet 5101 of the air duct 510, blows air onto the belt 400 and removes water, increasing the total dewatering rate of the brush roller 320 to 98%. Furthermore, the fan, in conjunction with the air outlet 5101 of the air duct 510, cools the belt 400, achieving both dewatering and cooling functions, improving production efficiency, and realizing integrated and efficient dewatering and cooling of the polymer belt 400. Specifically, the duct 510 is provided with an air outlet slope 511, and multiple air outlet holes 5101 are arranged in a dot matrix on the air outlet slope 511 to blow air obliquely towards the belt 400 in a direction opposite to the conveying direction. This enhances the scavenging effect on the surface of the belt 400 and reduces the probability of water droplets falling back onto the surface of the belt 400 through the oblique airflow away from the conveying direction. Optionally, the air outlet holes 5101 blow towards the belt 400 at a 45° angle. It is easy to understand that the dot matrix arrangement of the air outlet holes 5101 ensures that the air cooling uniformly covers the surface of the belt 400. Combined with the optimized oblique blowing angle, it significantly improves the air cooling water removal efficiency, while reducing the fan energy consumption, realizing the synergistic effect of blowing and air cooling, and further reducing the residual water rate on the surface of the belt 400. In addition, the combined effect of upper directional airflow cooling and lower roller contact cooling shortens the path length of the 400 belt from 60℃-90℃ to below 40℃ to less than 1.5 meters, significantly reducing space occupation compared to traditional air cooling and greatly improving the cooling rate.

[0034] Refer to Figure 3 In some embodiments of the present invention, the base 100 is equipped with a temperature sensor 110 and a humidity sensor 120. The temperature sensor 110 is located on the output side of the conveyor roller 220 and is used to detect the temperature of the belt 400. The humidity sensor 120 is located on the output side of the output roller and is used to detect the humidity of the belt 400. This allows for real-time monitoring of the temperature and humidity parameters on the output side of the belt 400, providing accurate feedback for the operation of the device. The temperature sensor monitors the cooling effect of the belt 400, and the humidity sensor detects the dehydration efficiency. The combination of these two sensors provides a clear picture of the device's operating status, offering data support for subsequent parameter adjustments in control methods. This ensures that the belt 400 reaches ideal temperature and drying conditions before entering the pelletizer, guaranteeing the quality stability of the pellets.

[0035] Refer to Figure 4According to an embodiment of the present invention, the control method is applied to an integrated water-cooling blower for polymer tape drawing according to an embodiment of the present invention, wherein the control method S100 includes the following steps: S110, Speed ​​control: Adjust the speed of the conveyor roller 220 according to the speed of the pelletizer to match the speed of the pelletizer; S120, Dehumidification control: Adjust the pressure of the brush roller 320 against the pull belt 400 and / or the rotation speed of the brush roller 320 according to the measurement value of the humidity detection sensor 120; S130, Temperature control: Adjust the temperature of coolant 2211, and / or the flow rate of coolant 2211, and / or the power of fan according to the measurement value of temperature detection sensor 110.

[0036] To address this, intelligent and precise operation of the device is achieved through triple coordinated regulation of speed control, dehydration control, and temperature control. Specifically, the speed of the conveyor roller 220 is adjusted according to the pelletizer speed to ensure that the conveyor belt 400 is synchronized with the pelletizing process, avoiding material accumulation or supply interruption. The pressure and speed of the brush roller 320 are dynamically adjusted based on humidity detection values, i.e., adjusting the scraping depth and scraping speed to optimize the dehydration effect and reduce water film residue. The parameters of the coolant 2211 and the fan power are adjusted based on temperature detection feedback to precisely control the cooling process of the conveyor belt 400. This control method combines mechanical adjustment with real-time monitoring, significantly improving the device's adaptability, ensuring the consistency of dehydration and cooling effects of the conveyor belt 400 under different operating conditions, reducing the need for manual intervention, and improving production efficiency and product quality.

[0037] Other configurations and operations of the control method according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
