Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a double-point adhesive liner uniform coating scraper. Background Technology

[0002] In the production and processing of double-point bonded interlinings, a coating doctor blade device is required to evenly apply polymer resin slurry to a wide-width (160cm-200cm) base fabric. Due to the wide width of the interlining product and the extremely high viscosity of the slurry (approximately 28,000 centipoise), existing slurry supply doctor blade equipment can no longer meet the process requirements of interlining production. The main problems are as follows: 1. The scraper structure design is unreasonable, the distribution of the slurry supply holes is unreasonable, and the slurry output cannot be controlled, making it impossible to ensure uniform slurry output from the left, center, and right sides during the production process; 2. The output rate cannot be adjusted for high-viscosity slurries; 3. The working angle adjustment range of the scraper is very small, which cannot meet the requirements of existing coating processes; 4. The scraper has poor manufacturing precision, is easily bent, and is easily damaged during disassembly and assembly. Utility Model Content

[0003] To address the technical problems of uncontrollable and uneven slurry output in the prior art, a double-point adhesive liner uniform coating scraper is provided.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a double-point adhesive lining uniform coating scraper, comprising a slurry delivery pipe, a scraper bed, and an aluminum cover plate. Its innovation lies in the following: multiple slurry outlet bolts are provided on the slurry delivery pipe, and slurry outlet holes are formed along the central axis of each bolt; the scraper bed is positioned at the tangent of the outer circle of the slurry delivery pipe, and coated scraper blades are provided on the scraper bed and fixed by a pressure plate and bolts; the aluminum cover plate is partially surrounding the outside of the slurry delivery pipe and is fixedly connected to the slurry delivery pipe by bolts, forming a primary slurry storage chamber between the aluminum cover plate and the slurry delivery pipe, the primary slurry storage chamber being located at the slurry outlet bolts; a slurry outlet slit is formed between the scraper bed and the aluminum cover plate, and a secondary slurry storage chamber is formed above the slurry outlet slit on the aluminum cover plate; the secondary slurry storage chamber contains adjustable square steel bars, which are controlled by adjusting bolts.

[0005] Furthermore, the size of the slurry outlet hole of the slurry outlet bolt is 2.0mm-5.0mm.

[0006] Furthermore, the slurry outlets are distributed at unequal intervals on the slurry delivery pipe.

[0007] Furthermore, the cutting bed is supported and fixed on the slurry delivery pipe by a support plate.

[0008] Furthermore, a protective cover plate is provided on the outside of the aluminum cover plate.

[0009] The beneficial effects of this utility model after adopting the above structure are as follows: In this invention, the slurry undergoes initial pressure and volume equalization in the primary slurry storage chamber before being extruded through the slurry outlet between the primary and secondary slurry storage chambers into the secondary slurry storage chamber. As the slurry passes through the secondary slurry storage chamber, the uniformity of slurry pressure and volume in the left, center, and right sections of the chamber can be adjusted by regulating the steel bars within the chamber. Subsequently, the slurry flows very evenly through the left, center, and right sections of the final slurry outlet like a water curtain, flowing towards the scraper and into the circular screen. The blade bed of the scraper of this utility model is fixed at the tangent position of the outer circle of the slurry pipe, so that when the scraper device is inside the circular screen, the coated scraper blade has a coating angle, and the working angle of the scraper blade can be adjusted significantly to adapt to the requirements of different production processes. The present invention uses unequally spaced slurry outlets on the slurry delivery pipe to achieve uniform slurry output from the left, center, and right sides of the primary slurry storage chamber during the first stage of pressure and quantity equalization.

[0010] The size of the slurry outlet hole of this invention can be adjusted in multiple levels from 2.0mm to 5.0mm to adapt to slurries of different viscosities and ensure the uniformity of slurry output; This utility model features precise structural dimensions, a straight cutting bed, easy assembly and disassembly, is not easily damaged, and has a longer service life.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] 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 specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0015] See Figure 1A double-point adhesive uniform coating scraper includes a slurry delivery pipe 1, a scraper bed 2, and an aluminum cover plate 3. Multiple slurry outlet bolts 4 are installed on the slurry delivery pipe 1, with slurry outlet holes 5 formed along the central axis of each bolt. The scraper bed 2 is positioned at the tangent to the outer circle of the slurry delivery pipe 1, and is equipped with coating scraper blades 6, which are fixed by a pressure plate 7 and bolts. The aluminum cover plate 3 partially surrounds the outside of the slurry delivery pipe 1 and is fixedly connected to it by bolts. A primary slurry storage chamber 8 is formed between the aluminum cover plate 3 and the slurry delivery pipe 1, located at the slurry outlet bolts 4. A slurry outlet slit 9 is formed between the scraper bed 2 and the aluminum cover plate 3. A secondary slurry storage chamber 10 is formed above the slurry outlet slit 9 on the aluminum cover plate. An adjustable square steel bar 11 is installed inside the secondary slurry storage chamber 10, and the adjustable square steel bar 11 is controlled by adjusting bolts 12. Specifically, the slurry in the slurry delivery pipe 1 is discharged from the slurry outlet hole 5 of the slurry outlet bolt 4. After being uniformly pressurized and distributed in the primary slurry storage chamber 8, it is squeezed outwards through the slurry outlet gap between the primary slurry storage chamber 8 and the secondary slurry storage chamber 10 (approximately 1.5 mm wide) and enters the secondary slurry storage chamber 10. As the slurry passes through the secondary slurry storage chamber 10, the uniformity of slurry pressure and quantity in the left, middle, and right sections of the secondary slurry storage chamber can be adjusted by regulating the adjustable square steel bar 11 within the secondary slurry storage chamber. The adjusting bolt 12 adjusts the height of the adjustable square steel bar 11, thereby controlling the slurry output. Afterwards, the slurry flows very evenly outwards through the left, middle, and right sections of the final slurry outlet gap, like a water curtain, and enters the circular screen through the scraper.

[0016] In this embodiment, in order to better control the amount of slurry discharged, the size of the slurry discharge hole 5 of the slurry discharge bolt 4 is set to 2.0mm-5.0mm, which can be adjusted by replacing the slurry discharge bolt 4.

[0017] In this embodiment, the slurry outlet holes 5 are distributed at unequal intervals on the slurry delivery pipe 1. The unequal intervals of the slurry outlet holes 5 on the slurry delivery pipe 1 are used to achieve a uniform slurry output from the left, center, and right sides of the primary slurry storage tank 8 during the first stage of pressure and quantity equalization.

[0018] In this embodiment, the blade bed 2 is supported and fixed to the grout delivery pipe 1 by a support plate 13. The support plate 13 fixes the blade bed 2 to the grout delivery pipe 1, which plays a stabilizing role and ensures that the blade bed 2 is always at the tangent position of the outer circle of the grout delivery pipe 1, that is, ensures that the coating scraper blade 6 is at the tangent position of the outer circle of the grout delivery pipe 1.

[0019] In this embodiment, a protective cover plate 14 is provided on the outside of the aluminum cover plate 3. The protective cover plate 14 protects the aluminum cover plate 3.

[0020] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
