Description

Technical Field

[0001] This application relates to the field of polyester filter cloth production, and more specifically, to a sizing and dewatering device. Background Technology

[0002] In the production process of polyester filter cloth, sizing and dewatering are two key steps. Sizing refers to applying a layer of sizing agent to the surface of polyester fibers to improve their strength and filtration performance. Dewatering refers to removing excess water generated during the sizing process to ensure the quality and performance of the filter cloth. This process requires the use of sizing and dewatering equipment.

[0003] In current sizing and dewatering equipment, polyester filter cloth is prone to residual spinning oil, weaving lint, environmental dust, broken fibers, and small hard impurities on its surface during spinning, weaving, and transportation. These impurities will directly enter the sizing and dewatering process with the cloth and seriously affect the production process and product quality. Specifically, the impurities will block the effective contact between the sizing agent and the polyester fibers, resulting in insufficient penetration and uneven adhesion of the sizing agent in some areas, which will lead to the formation of local sizing film defects or accumulation. Ultimately, this will cause the finished filter cloth to have an unbalanced strength distribution and fluctuate filtration accuracy. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a sizing and dewatering device. This device solves the problem that in existing technologies, polyester filter cloth is prone to residual spinning oil, weaving lint, environmental dust, broken fibers, and small hard impurities on its surface during spinning, weaving, and transportation. These impurities directly enter the sizing and dewatering process with the cloth and seriously affect the production process and product quality. Specifically, these impurities can prevent the effective contact between the sizing agent and the polyester fibers, resulting in insufficient penetration and uneven adhesion of the sizing agent in certain areas. This leads to the formation of local sizing film defects or accumulation, ultimately causing an imbalance in the strength distribution of the finished filter cloth and fluctuations in filtration accuracy.

[0006] To achieve the above objectives, this application provides the following technical solution: A sizing and dewatering device includes: a device body, with material inlets at both the front and rear ends of the device body, and a pre-cleaning mechanism installed at the front end of the device body; a sizing and dewatering mechanism is provided on the inner and outer sides of one side of the device body; the pre-cleaning mechanism includes a pair of side frames, and a cleaning component is installed in the middle of the pair of side frames; the cleaning component includes a first guide frame, and a dust removal component is provided on one side of the first guide frame.

[0007] Furthermore, the cleaning assembly includes a first drive screw, which is mounted on one side of the middle of a preset slot on the left side mounting frame. A first motor is installed at one end of the first drive screw, and a first screw sleeve is screwed around one section of the first drive screw. A first guide frame is fixed inside the first screw sleeve. A first guide rod is fixed on one side of the middle of the preset slot on the right side mounting frame. A second motor is mounted on the outside of one side of the first guide frame, and the output end of the second motor is connected to a first brush roller. The middle of the pair of side mounting frames is located at the first brush roller. A second brush roller is mounted below, and a rotating rod is provided on one side of the outer end of the right side mounting frame. A gear is fixed around the section of the rotating rod opposite to the shaft of the second brush roller, and a first synchronous pulley is fixed around the section of the rotating rod opposite to the shaft of the first brush roller. A cylinder is mounted on the outer side of the main body of the device, and the extended end of the cylinder is connected to a connecting guide shaft frame. A second synchronous pulley is provided around the middle section of the connecting guide shaft frame. A guide groove for guiding the connecting guide shaft frame is opened on the outer side of the main body of the device. A synchronous belt is sleeved on the outer side of the two first synchronous pulleys and the second synchronous pulley.

[0008] Furthermore, the first guide rod is connected to the first guide frame by a lifting guide connection.

[0009] Furthermore, the dust removal assembly includes a lower dust collection frame, which is fixedly mounted on the lower section of one side of a pair of side mounting frames. Connecting blocks are fixedly provided at the front ends of both ends of the first guide frame, and an upper dust collection frame is connected to the top of the two connecting blocks. Air ducts are provided on opposite sides of the same end of the upper and lower dust collection frames, and telescopic hoses are connected to the ends of the two air ducts. A suction air pipe is connected to one side of one of the air ducts.

[0010] Furthermore, the suction pipe is connected to another suction pipe through one of the air guide pipes and the telescopic hose, thereby forming a through suction passage with the upper suction frame and the lower suction frame respectively.

[0011] Furthermore, the sizing and dewatering mechanism includes a guide roller, which is disposed inside the main body of the device. A lower dewatering roller is provided on one side of the main body of the device. An inner frame is fixed on both sides of the upper part of one side of the main body of the device. A third motor is installed on the upper part of one of the inner frames. The output end of the third motor is connected to a second transmission screw. A second screw sleeve is screwed around one side of the second transmission screw. A second guide frame is fixed on the inner side of the second screw sleeve. A second guide rod is fixed in the middle of the other inner frame. An upper dewatering roller is installed below the second guide frame.

[0012] Furthermore, the second guide frame and its second guide rod are connected by a guide mechanism.

[0013] The beneficial effects of this application are as follows: Before the polyester filter cloth is fed into the sizing chamber from the feed inlet at the front of the device for sizing, the operator can first start the second motor to drive the first brush roller to rotate. The first synchronous pulley at the end of the first brush roller is driven by the meshing of the synchronous belt, which synchronously drives the second synchronous pulley and the first synchronous pulley at one end of the rotating rod to rotate synchronously. Gears are provided at the other end of the rotating rod corresponding to the shaft of the second brush roller. The second brush roller will rotate in the opposite direction to the first brush roller under the meshing action of the relative gears, thereby brushing away impurities from both sides of the polyester filter cloth in a relatively outward direction. Before this, the operator needs to start the industrial vacuum cleaner connected to the end of the suction pipe. The suction force generated by the vacuum cleaner will be transmitted to the upper and lower suction frames set opposite to each other through two air guide pipes and a telescopic hose. The suction port and cleaning point are precisely aligned to achieve the effect of suction along the direction. When polyester filter cloth of different thicknesses is involved in the operation, the operator can start the first motor to rotate the first transmission screw connected to it. The first screw sleeve that cooperates with the screw will carry the first guide frame and the first brush roller it carries. Under the guidance of the first guide rod, it will rise or fall, thereby adjusting the distance between the first brush roller and the second brush roller. At the same time, the cylinder will start synchronously, and its extended end will move forward or backward according to the actual situation. For example, when the distance between the first brush roller and the second brush roller decreases, the synchronous belt on the same side of the two will gradually loosen. At this time, the extended end of the cylinder will carry the connected guide shaft frame and the second synchronous pulley around it to move backward along the guide groove to tighten the synchronous belt and avoid structural failure.

[0014] After the polyester filter cloth enters the sizing chamber through the feed inlet at the front of the main body of the device, it will be conveyed sequentially along the separately set guide rollers to complete the sizing operation. Then, it will be dewatered by squeezing between the lower dewatering roller and the upper dewatering roller. After dewatering, it will be discharged from the feed inlet at the rear of the main body of the device. When processing polyester filter cloth of different thicknesses, the operator can start the third motor to drive the second transmission screw to rotate. The second screw sleeve that cooperates with the screw will carry the second guide frame and the upper dewatering roller it carries. Under the guidance of the second guide rod, it will be raised and lowered, thereby accurately adjusting the distance between the upper and lower dewatering rollers to adapt to the dewatering requirements of different thicknesses of cloth.

A guide frame 324 has a first guide rod 325 fixedly mounted on one side of the preset groove of the right side mounting frame 31. A second motor 326 is mounted on the outside of one side of the first guide frame 324, and the output end of the second motor 326 is connected to a first brush roller 327. A second brush roller 328 is mounted on the middle of a pair of side mounting frames 31 below the first brush roller 327. A rotating rod 329 is provided on one side of the outer end of the right side mounting frame 31. A gear 3210 is fixedly mounted around the section of the rotating rod 329 opposite to the shaft of the second brush roller 328, and a first synchronous pulley 3211 is fixedly mounted around the other section of the rotating rod 329 opposite to the shaft of the first brush roller 327. A cylinder 3212 is mounted on the outside of the main body 1, and the extended end of the cylinder 3212... A connecting guide shaft bracket 3213 is connected, and a second synchronous pulley 3214 is provided around the middle section of the connecting guide shaft bracket 3213. A guide groove 3215 is provided on the outer side of the main body 1 to guide the connecting guide shaft bracket 3213. A synchronous belt 3216 is sleeved on the outer side of the two first synchronous pulleys 3211 and the second synchronous pulley 3214. The first guide rod 325 is connected to the first guide frame 324 by a lifting guide connection. A dust removal component 33 is provided on one side of the first guide frame 324. The dust removal component 33 includes a lower dust suction frame 331, which is fixed to the lower section of one side of the middle of a pair of side mounting frames 31. Connecting blocks 332 are fixed to the front sections of both ends of the first guide frame 324, and an upper dust suction frame 33 is connected to the top of the two connecting blocks 332. 3. Air ducts 334 are provided on opposite sides of the same end of the upper vacuum frame 333 and the lower vacuum frame 331, and the ends of the two air ducts 334 are connected to telescopic hoses 335. One side of one of the air ducts 334 is connected to a suction air pipe 336. The suction air pipe 336 is connected to the other air duct 334 through one of the air ducts 334 and the telescopic hose 335, thus forming a through suction passage with the upper vacuum frame 333 and the lower vacuum frame 331 respectively. Before the polyester filter cloth is fed into the sizing chamber from the feed port 2 at the front end of the main body 1 for sizing operation, the operator can first start the second motor 326 to drive the first brush roller 327 to rotate. The first synchronous pulley 3211 at the end of the first brush roller 327 is pulled by the engagement of the synchronous belt 3216.The first synchronous wheel 3211 at one end of the rotating rod 329 rotates synchronously, while gears 3210 are provided at the other end of the rotating rod 329 corresponding to the shaft of the second brush roller 328. The second brush roller 328 rotates in the opposite direction to the first brush roller 327 under the meshing action of the gears 3210, thereby brushing away impurities from both sides of the polyester filter cloth outwards. Before this, the personnel need to start the industrial vacuum cleaner connected to the end of the suction pipe 336. The suction force generated by the vacuum cleaner will be transmitted sequentially through two air guide pipes 334 and a telescopic hose 335 to the upper suction frame 333 and the lower suction frame 331, which are set up opposite to each other. Since the suction ports of the two suction frames are precisely aligned with the cleaning points, the suction effect is achieved by following the direction of the suction. When different thicknesses of polyester filter cloth are involved in the operation, During installation, the operator can start the first motor 322 to rotate the first transmission screw 321 connected to it. The first screw sleeve 323, which cooperates with the screw, will carry the first guide frame 324 and its mounted first brush roller 327, rising or falling under the guidance of the first guide rod 325, thereby adjusting the distance between the first brush roller 327 and the second brush roller 328. Simultaneously, the cylinder 3212 will start synchronously, and its extended end will move forward or backward according to the actual situation. For example, when the distance between the first brush roller 327 and the second brush roller 328 decreases, the synchronous belt 3216 on the same side will gradually loosen. At this time, the extended end of the cylinder 3212 will carry the connected guide shaft frame 3213 and its surrounding second synchronous pulley 3214 backward along the guide groove 3215, tensioning the synchronous belt 3216 and preventing structural malfunctions.

[0024] It should be noted that the industrial vacuum cleaner and cylinder 3212 mentioned in this solution are existing technologies on the market. Their specific structure, working principle and control method have not been improved. Existing mature products that meet the working parameter requirements of this device can be directly selected for installation. The working principle of the industrial vacuum cleaner is to generate negative pressure by driving a fan with a motor, so that airflow is formed in the suction pipe, thereby sucking dust, debris and other particulate matter into the dust collection device to achieve the collection and separation of pollutants. The working principle of cylinder 3212 is to use compressed air as a power source. By controlling the opening and closing of the air intake and exhaust, the piston is pushed to make reciprocating linear motion in the cylinder, thereby outputting mechanical force to drive the actuator to complete the preset action.

[0025] The sizing and dewatering mechanism 4 includes a guide roller 41, which is disposed inside the main body 1. A lower dewatering roller 42 is provided on one side of the main body 1. An inner frame 43 is fixed on both sides of the upper part of one side of the main body 1. A third motor 44 is installed on the upper part of one of the inner frames 43. The output end of the third motor 44 is connected to a second transmission screw 45. A second screw sleeve 46 is screwed around one side of the second transmission screw 45. A second guide frame 47 is fixed on the inner side of the second screw sleeve 46. A second guide rod 48 is fixed in the middle of the other inner frame 43. An upper dewatering roller 49 is installed below the second guide frame 47. The second guide frame 47 and the second guide rod 48 are connected for guiding movement. After the polyester filter cloth enters the sizing chamber through the front feed port 2 of the main body 1, it will be sequentially conveyed along the separately set guide rollers 41 to complete the sizing operation. Then, it will be dewatered by squeezing between the lower dewatering roller 42 and the upper dewatering roller 49. After dewatering, it will be discharged from the rear feed port 2 of the main body 1. When processing polyester filter cloth of different thicknesses, the operator can start the third motor 44 to drive the second transmission screw 45 to rotate. The second screw sleeve 46, which cooperates with the screw, will carry the second guide frame 47 and the upper dewatering roller 49 it carries, and lift it up and down under the guidance of the second guide rod 48, thereby accurately adjusting the distance between the upper dewatering roller 49 and the lower dewatering roller 42 to adapt to the dewatering requirements of different thicknesses of cloth.

[0026] Working principle: In use, before the polyester filter cloth is fed into the sizing chamber from the feed port 2 at the front end of the main body 1 for sizing, the operator can first start the second motor 326 to drive the first brush roller 327 to rotate. The first synchronous pulley 3211 at the end of the first brush roller 327 is driven by the meshing of the synchronous belt 3216, which synchronously drives the second synchronous pulley 3214 and the first synchronous pulley 3211 at one end of the rotating rod 329 to rotate synchronously. The other end of the rotating rod 329 is equipped with gears 3210 at positions corresponding to the shaft of the second brush roller 328. The second brush roller 328 will rotate in the opposite direction to the first brush roller 327 under the meshing action of the relative gears 3210. This process involves brushing away impurities from both sides of the polyester filter cloth outwards. Before this, personnel need to start the industrial vacuum cleaner connected to the end of the suction pipe 336. The suction power generated by the vacuum cleaner will be transmitted sequentially through two air guide pipes 334 and a telescopic hose 335 to the upper suction frame 333 and the lower suction frame 331, which are positioned opposite each other. Since the suction ports of the two suction frames are precisely aligned with the cleaning points, the suction effect is achieved by following the direction of the suction. When polyester filter cloths of different thicknesses are involved in the operation, personnel can start the first motor 322 to rotate the first transmission screw 321 connected to it. The first screw sleeve 323, which cooperates with the screw, will carry the first guide frame 324 and its carrying device. The first brush roller 327 rises or falls under the guidance of the first guide rod 325, thereby adjusting the distance between the first brush roller 327 and the second brush roller 328. At the same time, the cylinder 3212 will start synchronously, and its extended end will move forward or backward according to the actual situation. For example, when the distance between the first brush roller 327 and the second brush roller 328 decreases, the synchronous belt 3216 on the same side of the two will gradually loosen. At this time, the extended end of the cylinder 3212 will guide the connected guide shaft frame 3213 and the surrounding second synchronous wheel 3214 to move backward along the guide groove 3215 to tension the synchronous belt 3216 and avoid structural operation failure. The polyester filter cloth passes through the front of the main body 1 of the device. After entering the sizing chamber through the end inlet 2, the material is sequentially conveyed along the separately set guide rollers 41 to complete the sizing operation. Then, it is dewatered by squeezing between the lower dewatering roller 42 and the upper dewatering roller 49. After dewatering, it is discharged from the rear end inlet 2 of the main body 1. When processing polyester filter cloth of different thicknesses, the operator can start the third motor 44 to drive the second transmission screw 45 to rotate. The second screw sleeve 46, which cooperates with the screw, will carry the second guide frame 47 and the upper dewatering roller 49 it carries. Under the guidance of the second guide rod 48, it will be raised and lowered, thereby accurately adjusting the distance between the upper dewatering roller 49 and the lower dewatering roller 42 to adapt to the dewatering requirements of different thicknesses of cloth.
