Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a thickness control mechanism for the production of waterproof coiled materials. Background Art

[0002] As an important material in building waterproof engineering, the thickness of waterproof coiled materials has a direct impact on waterproof performance and service life. Therefore, in the production process, it is crucial to precisely control the thickness of waterproof coiled materials. This can not only ensure the quality stability of waterproof coiled materials but also meet the specific requirements of different projects for waterproof performance.

[0003] The thickness control mechanism for the production of waterproof coiled materials is an essential equipment in the production process of waterproof coiled materials. It can solve problems such as low thickness control accuracy, low efficiency, and poor stability in traditional production methods, and improve the production efficiency and quality stability of waterproof coiled materials. With the continuous progress and innovation of technology, it is believed that more advanced thickness control mechanisms will be developed and applied to the production of waterproof coiled materials in the future.

[0004] In the process of processing and producing existing waterproof coiled materials, it is necessary to coat asphalt on the base fabric. During the asphalt coating process, a thickness adjustment mechanism is required to determine the thickness of the waterproof coiled material, and then the asphalt is poured between the pressure roller of the base fabric and the waterproof coiled material to coat the asphalt on the base fabric. However, after the pressure roller contacts the asphalt, the asphalt will adhere to the surface of the pressure roller. After the base fabric is processed by the pressure roller and conveyed to the next processing procedure, when the base fabric is conveyed to the next processing point, asphalt may fall on the surface of the base fabric coated with asphalt on one side of the pressure roller close to the next processing point, affecting the product quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Refer to Figures 1-7, A thickness control mechanism for the production of waterproof coiled materials, including an extrusion roller 1. A conveying roller 101 is arranged at the bottom of the extrusion roller 1. Connecting sleeves 2 are fixedly and rotatably connected to both ends of the conveying roller 101 and the extrusion roller 1. A lifting mechanism is arranged between the conveying roller 101 and the extrusion roller 1. Connecting rods 3 are fixedly installed on the two connecting sleeves 2 at both ends of the extrusion roller 1. The two connecting rods 3 are fixedly connected to a flattening block 4 at one end away from the extrusion roller 1; during the processing of waterproof coiled materials, the conveying roller 101 conveys the base fabric used for producing waterproof coiled materials. The thickness of the waterproof coiled material is controlled by the distance between the extrusion roller 1 and the conveying roller 101. The height of the extrusion roller 1 is changed through the lifting mechanism, so as to process waterproof coiled materials with different thicknesses correspondingly. When producing waterproof coiled materials, asphalt may fall onto the surface of the processed base fabric on the side of the extrusion roller 1 close to the flattening block 4, affecting the flatness of the product. By arranging a flattening block 4 behind the extrusion roller 1 to remove the excess asphalt material, the purpose of flattening the asphalt on the surface of the base fabric is achieved.

[0026] As a preferred technical solution of this embodiment, the lifting mechanism includes two support blocks 18. The two support blocks 18 are respectively fixedly installed on the two connecting sleeves 2 on the same side of the extrusion roller 1 and the conveying roller 101. A cylinder 19 is arranged between the two support blocks 18. The cylinder 19 is fixedly installed on the top of the support block 18 close to the conveying roller 101. The output end of the cylinder 19 is fixedly connected to the bottom of the support block 18 close to the extrusion roller 1; when it is necessary to adjust the height of the extrusion roller 1, the height of the extrusion roller 1 can be adjusted through the output end of the cylinder 19. Since the cylinder 19 adjusts the height of the connecting sleeve 2, and then adjusts the height of the extrusion roller 1, the bottom of the flattening block 4 fixedly connected to the connecting sleeve 2 always remains flush with the bottom of the extrusion roller 1.

[0027] As a preferred technical solution of this embodiment, an opening is arranged on the side of the flattening block 4 close to the extrusion roller 1. A protrusion 5 is arranged at the bottom of the opening of the flattening block 4. Discharge ports 6 are opened on both sides inside the flattening block 4. Drainage grooves 17 are opened at the top edges of the two discharge ports 6; when there is asphalt exceeding the specified thickness on the surface of the base fabric, the flattening block 4 removes the excess part. In order to avoid affecting subsequent products, the arranged protrusion 5 is used to prevent the removed asphalt from flowing back. The asphalt entering the flattening block 4 is discharged through the discharge ports 6, and the drainage grooves 17 are used to guide the discharge of asphalt.

[0028] As a preferred technical solution of this embodiment, scraping plates 7 are slidably arranged on both inner sides of the leveling block 4. Sliders 14 are fixedly installed at the tops of the two scraping plates 7. The two sliders 14 are slidably installed on the top of the leveling block 4. A ball screw 15 is rotatably connected to the top of the leveling block 4. The thread directions at both ends of the ball screw 15 are opposite. A motor 16 is fixedly installed at one end of the top of the leveling block 4. The output end of the motor 16 is fixedly connected to one end of the ball screw 15. After the asphalt enters the inside of the leveling block 4, since the flow rate of the asphalt is slow, the scraping plates 7 assist in discharging the asphalt. The motor 16 drives the ball screw 15 to rotate, so that the scraping plates 7 are driven by the sliders 14 to move inside the leveling block 4.

[0029] As a preferred technical solution of this embodiment, baffles 8 are rotatably connected to the bottoms of the two scraping plates 7. The rotation directions of the two baffles 8 face both ends of the leveling block 4. Connecting blocks 9 are rotatably connected to both sides of the side walls of the two baffles 8. Pulling springs 10 are fixedly connected to both of the two connecting blocks 9. The tops of the two pulling springs 10 are fixedly connected to the side walls of the scraping plates 7. A limiting block 11 is fixedly installed on the side of the scraping plate 7 near where the pulling spring 10 is installed. When the scraping plates 7 scrape the asphalt, when the two scraping plates 7 move towards the middle of the leveling block 4, in order to prevent the two scraping plates 7 from gathering the asphalt in the middle, causing the asphalt to be higher than the protrusion 5 and resulting in the backflow of the asphalt, baffles 8 are rotatably installed on the scraping plates 7. The baffles 8 and the pulling springs 10 are in a balanced state. Without external force, the baffles 8 and the scraping plates 7 are closed. During the process of the scraping plates 7 moving towards the middle of the leveling block 4, the baffles 8 are pushed open by the resistance of the asphalt, so that a gap appears at the bottom of the scraping plates 7, allowing the asphalt to flow through the gap and preventing it from gathering between the two scraping plates 7. When the two scraping plates 7 move towards both ends, the asphalt resistance causes the two baffles 8 to return to the inside of the scraping plates 7, closing the gap and driving the asphalt to move towards both ends to scrape the asphalt. The limiting block 11 is used to limit the rotation amplitude of the baffles 8.

[0030] As a preferred technical solution of this embodiment, magnets 12 are fixedly installed on the side walls of the two baffles 8 close to each other. Filling blocks 13 are fixedly installed on the side walls of the two scraping plates 7 close to the protrusion 5. By the mutual attraction of the two magnets 12, when the two scraping plates 7 meet, the two baffles 8 can timely return to the inside of the scraping plates 7, preventing the gap between the baffles 8 and the scraping plates 7 from closing untimely when the two scraping plates 7 move towards both ends, resulting in partial asphalt residue. The filling blocks 13 are attached to the inclined surface of the protrusion 5 to increase the sealing performance of the scraping plates 7.
