Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically to an auxiliary device for detecting the density of flame-retardant and UV-resistant composite curtains. Background Technology

[0002] The density of flame-retardant and UV-resistant composite curtains is an important indicator for measuring their weaving tightness and functional performance. It directly relates to the curtains' ability to block flames, their UV-blocking effect, and their overall durability. Therefore, it is necessary to design an auxiliary detection device for the density of flame-retardant and UV-resistant composite curtains to systematically detect their density.

[0003] A search revealed that Chinese utility model patent application CN220115784U proposes an "auxiliary device for fabric surface quality inspection." This device involves installing a lifting assembly and a translation assembly on a frame to mount a fabric unwinding roller and an auxiliary winding roller. The lifting assembly adjusts the height of the unwinding roller, while the translation assembly adjusts the horizontal position of the auxiliary winding roller. The combined action of these components controls the height and stroke of the unwinding process. During the unwinding process, defects, stains, and wrinkles on the fabric surface can be detected by visual inspection or in conjunction with image detection equipment.

[0004] However, in actual use, the aforementioned devices and similar existing devices lack an effective buffer structure for the instantaneous impact force when the curtains are placed. The vibration when the fabric contacts the detection platform can easily cause slight deviations in the optical detection elements, which in turn causes deviations in the laser penetration path and affects the accuracy of the density data. At the same time, traditional detection devices often use a single light source or a divergent array for laser emission. The laser beam is not strictly collimated and constrained, and it is easy to scatter when penetrating the curtain, resulting in uneven attenuation of the light intensity signal, which cannot accurately reflect the weave tightness of the fabric. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary detection device for the density of flame-retardant and UV-resistant composite curtains, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A density auxiliary detection device for flame-retardant and UV-resistant composite curtains includes:

[0008] The support platform has a placement slot at the top middle section;

[0009] The load-bearing groove plate is installed in the placement groove of the load-bearing platform through a damper installed at the bottom;

[0010] Several optical sensor plates are evenly fitted into the slots within the stress-bearing groove plate.

[0011] A telescopic column is fixed to one end of the top of the force-bearing platform;

[0012] The bottom end of the support arm is rotatably connected to the top end of the telescopic column;

[0013] An optical sensing component, mounted on the top of the support arm, is used to irradiate the flame-retardant and UV-resistant composite curtain placed between the load-bearing groove plate and the support arm in the form of a laser.

[0014] As the blind roller operates, the optical sensing component at the top of the support arm is activated, emitting multiple parallel laser beams that penetrate vertically into the flame-retardant and UV-resistant composite curtain below. The optical sensing plate, which is uniformly embedded in the force-bearing groove, receives the laser signal and obtains the density data of the flame-retardant and UV-resistant composite curtain at the corresponding position.

[0015] Furthermore, the optical sensing plate is an epoxy board with an integrated array of silicon-based photosensitive elements. A high-transparency quartz glass layer is attached to the top surface of the epoxy board. The array of silicon-based photosensitive elements is electrically connected to a signal amplification module embedded in the side wall of the stress-bearing groove plate via a flexible ribbon cable, which is used to convert the received light intensity signal after the laser penetrates the curtain into a linear electrical signal.

[0016] Furthermore, a control terminal is fixed at the top of the support arm away from the optical sensing component, and the control terminal is electrically connected to the optical sensing plate and the optical sensing component.

[0017] Furthermore, the optical sensing component includes:

[0018] A laser emitter, mounted at one end of the top of the support arm, is used to emit a parallel laser beam; the laser emitter is an array of laser diodes.

[0019] The channel tube, installed at the emitting end of the laser emitter, is used to constrain and collimate the multiple laser beams emitted by the array laser diode assembly one by one, ensuring that each laser beam remains parallel before penetrating the curtain.

[0020] The channel tube is a hollow metal tube that corresponds one-to-one with the array laser diodes. A columnar convex lens is embedded inside the tube, and the inner wall of the tube is coated with an anti-reflective aluminum film.

[0021] The light-emitting assembly, assembled inside the support arm, is used to receive laser light from the channel tube.

[0022] Furthermore, the light-emitting component includes:

[0023] Several transparent contact balls are evenly rotated and connected to the contact grooves opened at the bottom of the support arm;

[0024] An associated channel tube is interspersed between each contact transparent sphere in the coaxial direction, and one end of the associated channel tube is connected to the channel tube.

[0025] Furthermore, as the laser emitter operates, the laser-associated channel tube transmits the laser to the corresponding contact transparent ball. The contact transparent ball is rotatably connected to the contact groove at the bottom of the support arm. The bottom of the contact transparent ball is in close contact with the flame-retardant and UV-resistant composite functional curtain surface placed on the stress-bearing groove plate. After the laser is refracted by the spherical surface of the high-refractive-index optical glass of the contact transparent ball, it forms a point source laser beam perpendicular to the curtain surface.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] This flame-retardant and UV-resistant composite curtain density auxiliary detection device effectively counteracts the instantaneous impact force when the curtain is placed by using the damper buffer design at the bottom of the force groove plate, avoiding detection deviation caused by vibration of the optical sensing plate and ensuring the stability of the detection environment. In addition, the combination of array-type silicon-based photosensitive element, high-transparency quartz glass layer and signal amplification module ensures the receiving sensitivity and linear conversion accuracy of light intensity signal, ensuring that density data at each curtain position can be fed back.

[0028] In addition, the combination of the telescopic column and the rotatable bearing arm allows for flexible adjustment of the height and illumination angle of the optical sensing component, adapting to the detection needs of curtains of different sizes and thicknesses, thus enhancing the versatility of the device.

[0029] The collimation effect of the cylindrical convex lens inside the channel tube and the low-loss characteristics of the anti-reflective aluminum film strictly ensure the parallelism of the laser beam and reduce energy attenuation during transmission.

[0030] The rotating connection structure of the contact transparent ball not only achieves perpendicular incidence of laser light onto the curtain surface, avoiding detection errors caused by angular deviation, but also adapts to slight unevenness on the curtain surface, ensuring the continuity of the detection process.

[0033] Figure 3 This is a diagram showing the internal structure of the present invention.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Before understanding the technical solution proposed in this application, it should be clear that the actual application scenario of this technical solution is the rapid density detection stage of flame-retardant and UV-resistant composite curtains on the production line. When the curtain fabric is transported from the unwinding mechanism to the detection area, the device needs to complete the density data collection while keeping the fabric in continuous motion, and the detection process should not cause damage to the fabric surface or cause stretching deformation.

[0037] like Figures 1-3 As shown, this solution includes:

[0038] The top middle section of the force-bearing platform 1 has a precisely machined placement groove;

[0039] The load-bearing groove plate 3 is stably installed in the placement groove of the load-bearing platform 1 by the damper 10 installed at the bottom, and the damper 10 effectively absorbs vibration.

[0040] Several optical sensing plates 2 are evenly fitted into the slots within the force-bearing groove plate 3. The slots are designed to be evenly spaced to ensure sensing accuracy.

[0041] The telescopic column 4 is vertically fixed to one end of the top of the force-bearing platform 1, and its height is adjustable to accommodate different curtain thicknesses.

[0042] The bottom end of the support arm 9 is rotatably connected to the top of the telescopic column 4 via a precision bearing, enabling flexible movement;

[0043] An optical sensing component, mounted on the top of the support arm 9, is specifically designed to irradiate and measure the physical properties of the flame-retardant and UV-resistant composite curtain placed between the stress-bearing groove plate 3 and the support arm 9 using a high-precision laser.

[0044] It is worth noting that, as the blind roller operates at a constant speed, the optical sensing component at the top of the support arm 9 is automatically activated, emitting multiple strictly parallel laser beams. These laser beams penetrate vertically through the flame-retardant and UV-resistant composite curtain below, while the optical sensing plate 2, which is uniformly embedded in the force-bearing groove plate 3, synchronously receives the laser signals after penetration. By analyzing the changes in light intensity, the density data of the flame-retardant and UV-resistant composite curtain at the corresponding position is obtained in real time, realizing non-contact measurement.

[0045] As a supplement to the above, in this embodiment, the optical sensing plate 2 is made of a high-strength epoxy board and integrates a high-sensitivity array-type silicon-based photosensitive element. A layer of high-transmittance quartz glass is tightly bonded to the top surface of the epoxy board to protect the photosensitive element from dust. The array-type silicon-based photosensitive element is electrically connected to a low-noise signal amplification module embedded in the side wall of the stress-bearing groove plate 3 via a flexible cable. This module efficiently converts the received light intensity signal after the laser penetrates the curtain into a linear electrical signal and filters out interference to ensure data accuracy.

[0046] Furthermore, it should be noted that in this technical solution, a control terminal 5 is firmly fixed at the top of the support arm 9, away from the optical sensing component. The control terminal 5 is directly electrically connected to the optical sensing plate 2 and the optical sensing component via a cable, and is used to coordinate laser emission, signal acquisition and data processing, and to display the density distribution map in real time.

[0047] It is worth noting that in this technical solution, the optical sensing components include: a laser emitter 6, which is securely mounted at one end of the top of the support arm 9, and adopts an array-type laser diode assembly to output a parallel laser beam with a stable wavelength; a channel tube 7, which is precisely mounted at the emitting end of the laser emitter 6, with each channel tube 7 corresponding to one laser diode, used to constrain and collimate the multiple laser beams emitted by the array-type laser diode assembly one by one, and through internal optical design to ensure that each laser beam remains strictly parallel before penetrating the curtain, avoiding divergence; the channel tube 7 is a hollow metal tube that corresponds one-to-one with the array-type laser diodes, with a cylindrical convex lens embedded inside the tube to focus the beam, and the inner wall of the tube is uniformly coated with an anti-reflective aluminum film to minimize light loss; and a light emission assembly, which is compactly assembled in the internal cavity of the support arm 9, used to efficiently receive and guide the laser from the channel tube 7 to the surface of the curtain.

[0048] As a supplement to the above, in this technical solution, the light-emitting component specifically includes: a number of contact transparent spheres 8, which are uniformly rotatably connected to the contact grooves opened at the bottom of the support arm 9 through low-friction bearings. The contact grooves are designed as spherical concave surfaces, allowing the spheres to rotate freely. Each contact transparent sphere 8 in the coaxial direction is precisely interspersed with an associated channel tube 11. One end of the associated channel tube 11 is seamlessly connected to the channel tube 7 to form a continuous optical path.

[0049] It is worth noting that in this technical solution, with the stable operation of the laser emitter 6, the laser is efficiently transmitted to the corresponding contact transparent ball 8 through the associated channel tube 11. The contact transparent ball 8 is rotatably connected in the contact groove at the bottom of the bearing arm 9, which can adapt to the unevenness of the curtain surface. Its bottom end forms a tight contact with the flame-retardant and UV-resistant composite curtain surface placed on the force-bearing groove plate 3. After the laser is precisely refracted by the high refractive index optical glass sphere of the contact transparent ball 8, scattering is eliminated, and a high-intensity point source laser beam perpendicular to the curtain surface is formed.

[0050] It should be noted that, in actual operation, when the flame-retardant and UV-resistant composite curtain is uniformly conveyed from the unwinding mechanism of the production line to the detection area, the telescopic column 4 automatically adjusts its height according to the preset curtain thickness parameters, so that the contact transparent ball 8 at the bottom of the support arm 9 lightly touches the curtain surface, avoiding compression or stretching deformation of the fabric. Subsequently, the support arm 9 rotates slightly in sync with the direction of curtain movement through the rotating connection structure at the top, ensuring that the contact transparent ball 8 always maintains dynamic contact with the curtain surface. At the same time, the laser emitter 6 is activated, and the array laser diode assembly emits multiple laser diodes. After being collimated by the cylindrical convex lens and constrained by the anti-reflective aluminum film in the channel tube 7, the laser beam forms a strictly parallel laser beam. It is transmitted to the contact transparent ball 8 through the associated channel tube 11. After being refracted by its optical glass spherical surface, it penetrates the moving curtain. At the same time, the optical sensing plate 2 in the force groove plate 3 synchronously receives the laser signal after penetration. The array-type silicon-based photosensitive element converts the light intensity signal into a linear electrical signal. After the signal amplification module filters out interference, it is transmitted to the control terminal 5. The control terminal 5 processes the data in real time, generates the curtain density distribution curve, and marks and displays abnormal data, realizing real-time quality monitoring in the production process.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
