Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber cloth detection, in particular to a glass fiber cloth defect detection device. Background Art

[0002] Fiberglass cloth is also known as fiberglass geotextile. It is a geosynthetic material widely used in civil engineering. It is mainly a geosynthetic material composed of glass fiber and short-fiber needle-punched non-woven fabric. Fiberglass cloth is mainly composed of glass fiber and short-fiber needle-punched non-woven fabric, and is an inorganic non-metallic material with excellent performance.

[0003] Generally, fiberglass cloth can be regarded as a uniform material. However, when the fiberglass cloth has defects (such as metal wires, hollow missing weaves, uneven weaving), the fiberglass cloth cannot evenly disperse the tension when it is pulled, causing the surface of the fiberglass cloth to be unevenly stressed during tension testing and cause damage.

[0004] Therefore, those skilled in the art provide a glass fiber cloth defect detection device to perform defect detection on the glass fiber cloth. Utility Model Content

[0005] The purpose of the utility model is to provide a glass fiber cloth defect detection device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A glass fiber cloth defect detection device, wherein a working groove is provided on one side of the shell, a detection unit for detecting the tensile state of the glass fiber cloth is fixedly connected to the inner wall of the upper end of the working groove, and a conveying mechanism for transporting the glass fiber cloth is provided below the working groove located below the detection unit.

[0008] Furthermore, the conveying mechanism includes a conveying component, a torque component and a transmission component. Two groups of conveying components are arranged in the working groove, one side of which is connected to a torsion component for adjusting torque, and one side of the other group of conveying components is connected to a transmission component for conveying glass fiber cloth.

[0009] Furthermore, the conveying assembly includes rotating roller one and rotating roller two. The inner wall of the lower end of the working groove is rotatably connected to rotating roller one through a support column, and the inner wall of the upper end of the working groove is rotatably connected to rotating roller two through an elastic member. Rotating roller two is located above rotating roller one and a gap is left between them for the glass fiber cloth to pass through.

[0010] Furthermore, the torque assembly includes a support ring, a threaded rod and a knob. A circular groove is provided on one side of the elastic member and the support column. A knob is provided on a sliding sleeve in the circular groove. A threaded rod is fixedly connected to the side of the knob close to the conveying assembly. The threaded rod is connected to the conveying assembly through a threaded connection. The outer wall sliding sleeve of the threaded rod is provided with a plurality of support rings arranged in the circular groove.

[0011] Furthermore, one side of the support ring is convex to form a trumpet shape, the inner diameter of the support ring is larger than the outer diameter of the threaded rod, and the outer diameter of the support ring is smaller than the diameter of the circular groove.

[0012] Furthermore, the transmission assembly includes pulley 1, pulley 2 and an elastic part, the rotating roller 1 passes through the support column and is fixedly connected to pulley 1, the rotating roller 2 passes through the elastic part and is fixedly connected to pulley 1, one side of the support column is rotatably connected to pulley 2 through the elastic part, and the two pulleys 1 and 2 are driven by a belt.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] , through the provided conveying mechanism, the glass fiber cloth can be transported and tensile tested at the same time, which is convenient for continuous transportation and inspection of the glass fiber cloth. If the glass fiber cloth has defects (such as metal wire, hollow missing weaving, uneven weaving), the glass fiber cloth will disperse the tensile force unevenly, causing the glass fiber cloth to be damaged when it is pulled. Subsequently, an alarm can be issued through the detection unit to locate the defective part.

[0015] , By setting the elastic parts, the conveying component can automatically match the glass fiber cloths of different thicknesses, so that the use range of the detection device is wider.

[0016] , by setting the support ring to be in a trumpet shape, the support ring can disperse the pressure through the trumpet shape when it is squeezed, so that the support ring can have stronger pressure resistance. The outer diameter of the support ring is smaller than the diameter of the circular groove, and the inner diameter is larger than the outer diameter of the threaded rod. When the support ring is squeezed and deformed, it can avoid contact with the threaded rod and the circular groove to accelerate wear, thereby extending the service life of the support ring.

[0017] , by connecting the pulley 2 and the support column through an elastic part, when the conveying mechanism conveys glass fiber cloths of different thicknesses and causes the distance between the rotating roller 1 and the rotating roller 2 to change and pull the belt, the elastic part deforms to absorb the force of the belt pressing the pulley 2, thereby avoiding the belt from breaking.

[0023] Below, the invention is further described in conjunction with the accompanying drawings and specific embodiments: Embodiment 1:

[0024] See also Figure 1-2 According to a glass fiber cloth defect detection device of an embodiment of the utility model, a working groove 2 is opened on one side of the shell 1, and a detection unit 3 for detecting the tensile state of the glass fiber cloth is fixedly connected to the inner wall of the upper end of the working groove 2. The working groove 2 is located below the detection unit 3 and is provided with a conveying mechanism 4 for transporting the glass fiber cloth.

[0025] Through the above scheme of the utility model, the detection unit 3 (including a microwave transmitter for waveguide and a computer for analyzing reflected waves) can be set up to analyze and detect the reflected waves after the waveguide contacts the glass fiber cloth, and the conveying mechanism 4 can continuously transport the glass fiber cloth while stretching the glass fiber cloth to test the tensile condition of the glass fiber cloth. If the glass fiber cloth has defects such as metal wire, hollow missing weaving, and uneven weaving, the tensile force of the glass fiber cloth will be unevenly dispersed, so that the glass fiber cloth will be damaged when it is pulled, and the reflected wave will also change. Then, an alarm can be issued through the detection unit 3 to locate the defective part. Embodiment 2:

[0026] See also Figure 1The conveying mechanism 4 includes a conveying component 41, a torsion component 42 and a transmission component 43. Two groups of conveying components 41 are arranged in the working groove 2, one side of which is connected to a torsion component 42 for adjusting the torsion, and one side of the other group of conveying components 41 is connected to a transmission component 43 for conveying the glass fiber cloth. The conveying component 41 includes a rotating roller 1 411 and a rotating roller 2 412. The inner wall of the lower end of the working groove 2 is rotatably connected to the rotating roller 1 411 through a support column 5, and the inner wall of the upper end of the working groove 2 is rotatably connected to the rotating roller 2 412 through an elastic member 6. The rotating roller 2 412 is located above the rotating roller 1 411 and a gap is left between each other for the glass fiber cloth to pass through.

[0027] Through the above scheme of the utility model, the gap between the conveying roller 1 411 and the conveying roller 2 412 can make the glass fiber cloth pass through the gap and then be transported, and the elastic member 6 arranged between the conveying roller 2 412 and the shell 1 can make the conveying roller 412 close to the glass fiber cloth through the elastic force provided by the elastic member 6 to the conveying roller 412, so that the glass fiber cloth is more stable during transportation, and when the thickness of the glass fiber cloth changes, the conveying roller 412 can be moved up by squeezing the elastic member 6, and the glass fiber cloth of different thicknesses can be automatically matched, so that the use range of the detection device is wider. The torque required for the rotation of the rotating roller 1 411 and the rotating roller 2 412 can be adjusted by the torque assembly 42 arranged in one set of the conveying mechanism 41, so that when the motor (existing technology, no more details) drives the other set of conveying mechanism 41 to move the glass fiber cloth, a tensile force is generated on the glass fiber cloth, thereby performing a tensile test on the glass fiber cloth. Embodiment three:

[0028] See also Figure 1-2The torque assembly 42 includes a support ring 421, a threaded rod 422 and a knob 423. A circular groove 7 is provided on one side of the elastic member 6 and the support column 5. A knob 423 is provided in a sliding sleeve in the circular groove 7. A threaded rod 422 is fixedly connected to a side of the knob 423 close to the conveying assembly 41. The threaded rod 422 is connected to the conveying assembly 41 through a thread. The outer wall of the threaded rod 422 is provided with a plurality of support rings 421 arranged in the circular groove 7. One side of the support ring 421 is convex to form a trumpet shape. The inner diameter is larger than the outer diameter of the threaded rod 422, the outer diameter of the support ring 421 is smaller than the diameter of the circular groove 7, the transmission assembly 43 includes a pulley 1 431, a pulley 2 432 and an elastic part 433, the rotating roller 1 411 passes through the support column 5 and is fixedly connected to the pulley 1 431, the rotating roller 2 412 passes through the elastic member 6 and is fixedly connected to the pulley 1 431, one side of the support column 5 is rotatably connected to the pulley 2 432 through the elastic part 433, and the two pulleys 1 431 and the pulley 2 432 are driven by a belt.

[0029] Through the above scheme of the utility model, the threaded rod 422 can be driven to rotate and enter the conveying component 41 by rotating the knob 423, so that the knob 423 slides into the circular groove 7 to squeeze the support ring 421, so that the pressure between the support rings 421 increases, thereby changing the resistance required when the conveying component 41 rotates, thereby adjusting the tension required for the tensile test of the glass fiber cloth according to the thickness of the glass fiber cloth, and the support ring 421 is set to be a trumpet shape, and the two adjacent support rings 421 are in conflict with each other, so that the support ring 421 disperses the pressure through the trumpet shape when being squeezed, so that the support ring 421 can have a stronger compression resistance, and the outer diameter of the support ring 421 is smaller than the diameter of the circular groove 7, and the inner diameter is larger than the outer diameter of the threaded rod 422, so that when the support ring 421 is squeezed and deformed, it can avoid contact with the threaded rod 422 and the circular groove 7 to accelerate wear, thereby extending the service life of the support ring 421. By providing a belt transmission between pulley 1 431 and pulley 2 432, and connecting pulley 2 432 to support column 5 via elastic portion 433, when conveying fiberglass cloth of different thicknesses causes the distance between rotating roller 1 411 and rotating roller 2 412 to change and pull the belt, the elastic portion 433 deforms to absorb the force of the belt pressing pulley 2 432, thereby preventing the belt from breaking.

[0030] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0031] In actual application, when the glass fiber cloth is transported by the motor-driven conveying mechanism 41, the glass fiber cloth will be prevented from moving by the resistance provided by the torsion assembly 42, thereby generating tension on the glass fiber cloth. The glass fiber cloth is subjected to a tension test. When there are defects in the glass fiber cloth, the tension on the glass fiber cloth cannot be evenly dispersed, resulting in damage to the defective part of the glass fiber cloth. Subsequently, an alarm is sounded by the detection unit 3, so that the defective part of the glass fiber cloth can be quickly located.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
