Description

Technical Field

[0001] The invention relates to the technical field of glass fibers, in particular to an automatic detection device for the qualified rate of glass fiber products. Background Art

[0002] Fiberglass is an inorganic, non-metallic material with excellent properties, available in a wide variety. Its advantages include excellent insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but its disadvantages include brittleness and poor wear resistance. It is manufactured from six minerals: pyrophyllite, quartz sand, limestone, dolomite, colemanite, and magnesiaite, through a process of high-temperature melting, drawing, winding, and weaving. The surface of the fiberglass yarn is coated with a slurry to enhance its wear resistance.

[0003] Glass fiber cloth needs to undergo multiple tests during production, including tensile testing, bending testing, and pressure testing. Multiple devices are required to perform the above tests, such as tensile testing machines, bending testing machines, and pressure testing machines. Single-item testing with a single device wastes time and effort, which in turn reduces the efficiency of the test.

[0004] In order to overcome the above-mentioned defects, the prior art (publication number: CN221485063U, Chinese patent application date: 2024-08-06) discloses a glass fiber cloth performance testing device. Its technical solution includes: a base plate, a first clamp, a clamping plate and a screw. The four sides of the top surface of the base plate are fixed with sliding rods, the top of the sliding rods is connected to a top box, and one end of the outer bottom surface of the top box is connected to a second clamp through a tension sensor. A sliding sleeve slides in the middle of the sliding rod, and the sliding sleeve is installed through the four sides of the flat plate. A pressure block is fixed in the middle of the bottom surface of the flat plate, and the first clamp is fixed to one end of the top surface of the flat plate. The utility model uses a hydraulic cylinder to push the flat plate. The bottom surface of the flat plate is installed with a pressure block. The pressure block can cooperate with the base to perform compression resistance testing on the glass fiber cloth, and the top surface of the flat plate is installed with a first clamp. The first clamp can cooperate with the second clamp to perform tensile testing on the glass fiber cloth. Both tests are performed using one device, achieving the effect of convenient operation and improved detection efficiency.

[0005] Although the above design can solve the above problems, it is inconvenient to clean the equipment after the processing operation is completed, so that long-term continuous use will cause the glass fiber being tested to become entangled, and the messy testing environment will reduce the processing accuracy and affect the work efficiency of the cleaning staff. At the same time, the collection process during cleaning relies on manual labor, which is too inefficient and cannot comprehensively clean the entire processing area, leaving residues in the gaps that affect subsequent testing and processing work. Summary of the Invention

At the same time, the collection process during the cleaning work relies on manual efficiency which is too low, and the overall cleaning of the processing area cannot be carried out comprehensively, resulting in residues left in the gaps affecting subsequent detection and processing work.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an automatic detection device for the qualified rate of glass fiber products, comprising a central processing unit, a rotating placement plate is installed on the inner surface of the central processing unit, and a sliding transmission mechanism for moving the sliding collection box outward is installed above the rotating placement plate, the sliding transmission mechanism includes a drive motor, and the drive motor is fixedly installed on the inner surface of the central processing unit, a power distribution cabinet is installed on the lower surface of the central processing unit, and an electronic balance is installed on the upper surface of the power distribution cabinet, a rotating support frame is installed on the upper surface of the power distribution cabinet, and an engaging elastic mechanism for rotating the cleaning fan is installed inside the rotating support frame.

[0008] Furthermore, the engaging elastic mechanism includes a limiting sliding plate, and the limiting sliding plate is fixedly installed on the upper surface of the distribution cabinet, and the outer surface of the limiting sliding plate is installed with a resisting transverse rack, and the resisting transverse rack slides along the outer surface of the limiting sliding plate, and the upper surface of the distribution cabinet is installed with a stabilizing rotating frame.

[0011] Furthermore, the cleaning fan is rotatably installed inside the rotating support frame, and a connecting transmission belt is installed on the outer surface of the center position of the cleaning fan, the other end of the inner surface of the connecting transmission belt is fitted on the outer surface of the second transmission bevel gear, and a reset extrusion spring is installed on the side of the distribution cabinet, the front end of the reset extrusion spring contacts the horizontal rack, and the rotating support frame, the cleaning fan and the connecting transmission belt are installed in two groups symmetrically about the center point of the second transmission bevel gear.

[0012] Furthermore, a pneumatic tube is installed on the side of the distribution cabinet, and the other end of the pneumatic tube is installed on the side of the central processing unit. An extended recovery rod is installed on the outer surface of the output end of the drive motor, and a recovery connecting wire group is installed on the outer surface of the extended recovery rod.

[0013] Furthermore, a rotating placement plate is installed on the upper surface of the distribution cabinet, and the end of the recovery connection wire group is fixedly installed on the upper surface of the rotating placement plate. An auxiliary rolling rack is installed on the inner surface of the central processing unit, and the recovery connection wire group slides along the top of the auxiliary rolling rack.

[0014] Furthermore, a semicircular resistance block is installed on the upper surface of the rotating placement plate, and a sliding collection box is installed inside the distribution cabinet.

Such a design makes the cleaning work of the equipment more convenient, and at the same time, the glass fiber will not be entangled, which improves the processing efficiency and does not affect the work efficiency of the cleaning staff;

[0018] Furthermore, the movement of the rotating placement plate will cause the interfering transverse rack to interfere backwards through the fixed interference block, so that the first transmission bevel gear and the second transmission bevel gear are meshed with each other. At this time, the rotation of the second transmission bevel gear will drive the cleaning fan to rotate through the connecting transmission belt, so that the outer surface of the raised rotating placement plate is cleaned. This design makes the collection efficiency higher during the cleaning work, and can more comprehensively clean the processing area as a whole without leaving residue in the gap to affect the subsequent inspection and processing work;

[0019] Furthermore, when the conflicting transverse rack slides backward, the reset extrusion spring will continue to perform the same conflict extrusion work, so that the conflicting transverse rack can be quickly reset when it is not conflicted by the front end, and the detection effect of the pneumatic tube and the electronic balance is more accurate.

It discloses: a pneumatic tube 2 is installed on the side of the distribution cabinet 4, and the other end of the pneumatic tube 2 is installed on the side of the central processing unit 1, an extension recovery rod 15 is installed on the outer surface of the output end of the drive motor 12, and a recovery connection line group 13 is installed on the outer surface of the extension recovery rod 15, a rotating placement plate 6 is installed on the upper surface of the distribution cabinet 4, and the end of the recovery connection line group 13 is fixedly installed on the upper surface of the rotating placement plate 6, an auxiliary rolling frame 14 is installed on the inner surface of the central processing unit 1, and the recovery connection line group 13 slides along the top of the auxiliary rolling frame 14, and a semi-rotating plate 6 is installed on the upper surface of the rotating placement plate 6. Circular contact block 17, and a sliding collection box 18 is installed inside the distribution cabinet 4, and a semicircular contact plate 19 is installed on the outer surface of the sliding collection box 18, and the moving trajectory of the semicircular contact block 17 contacts the outer surface of the semicircular contact plate 19, the rotating placement plate 6 is rotatably installed on the upper surface of the distribution cabinet 4, and the sliding collection box 18 is slidably installed inside the distribution cabinet 4, the upper surface of the rotating placement plate 6 is installed with a fixed contact block 16, and the sliding collection box 18 and the semicircular contact plate 19 are integrated into one design, the extended recovery rod 15 is fixedly connected to the upper surface of the rotating placement plate 6 through the end of the recovery connection wire group 13 to form a transmission structure, and the outer surface of the recovery connection wire group 13 contacts the top inner surface of the auxiliary rolling frame 14 to form a sliding structure, the inner surface of the distribution cabinet 4 contacts the outer surface of the sliding collection box 18 to form a sliding structure, and the contact surfaces of the semicircular contact block 17 and the semicircular contact plate 19 are both semicircular designs.

[0035] During the rotation of the rotating placement plate 6, the fixed interference block 16 fixedly installed on the top will be driven to move synchronously, and during the rotation of the fixed interference block 16, it will interfere with the interference horizontal rack 20. As the end of the interference horizontal rack 20 is interfered, it will slide along the outside of the internally nested limiting sliding plate 21. Since the limiting sliding plate 21 is fixedly installed on the top of the distribution cabinet 4, the interference horizontal rack 20 will slide laterally stably.
