Description

Technical Field

[0001] The present invention belongs to the field of surface sizing detection of glass fiber yarns, and specifically relates to a device for detecting the surface sizing of glass fiber yarns. Background Art

[0002] Glass fiber yarn is an inorganic fiber material made by drawing glassy materials after high-temperature melting, and is widely used in the fields of industry, construction, and composite materials.

[0003] The detection of the surface sizing of glass fiber yarn is a key link to ensure its performance stability and processing adaptability, involving multiple dimensions such as composition, thickness, and adhesion. When existing equipment detects the surface sizing of glass fiber yarn, it is necessary to fully spread out the glass fiber yarn. The methods adopted by existing equipment include manual flattening and machine scraping, both of which have various problems, including low efficiency and easy damage to fibers. Therefore, a device for detecting the surface sizing of glass fiber yarn is proposed. Summary of the Invention

Some simplifications or omissions may be made in this part, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this part, the abstract, and the title, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the following technical problems in the prior art: The methods adopted by existing equipment, including manual flattening and machine scraping, have various problems, including low efficiency and easy damage to fibers.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A device for detecting the surface sizing of glass fiber yarns, including a receiving table, on the upper side of which a first long cylinder, a detecting member, a cutting table, a tensioning mechanism, a smoothing assembly, and a second long cylinder are installed. The smoothing assembly is located in the space between the first long cylinder and the detecting member, and the smoothing assembly smooths the glass fiber yarn, and the tensioning mechanism tensions and straightens the glass fiber yarn.

[0007] As a preferred technical solution of a device for detecting the surface sizing of glass fiber yarns, the glass fiber yarn is wound around a reel, the reel is installed on the first long cylinder, and the glass fiber yarn sequentially passes through the smoothing assembly, the detecting member, the cutting table, the tensioning mechanism, and the second long cylinder;

[0008] The smoothing assembly generates vibrations on the glass fiber yarn, so that the glass fiber yarn removes wrinkles and is smoothed during the vibration, avoiding parts of the glass fiber yarn covering each other, and preventing covering and detection dead angles when detecting the glass fiber yarn.

[0009] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the first long cylinder, the detecting member, the cutting table and the second long cylinder are equipment that can be adopted in the market. There are winding wheels installed on both the first long cylinder and the cutting table, and the winding wheels wind the glass fiber yarns.

[0010] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, a flattening assembly can also be installed between the tensioning mechanism and the second long cylinder;

[0011] The flattening assembly includes a first strip. The first strip is installed on the receiving table, and the lower edge of the covering piece is provided with the first strip. The lower edge of the covering piece is provided with a first deformation member, an intermittent pressing member and a shaking assembly. The intermittent pressing member can force the shaking assembly to move up and down. The shaking assembly alternately drives the glass fiber yarns to shake. The first deformation member is located on both sides of the shaking assembly and receives the glass fiber yarns.

[0012] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the first strip receives the covering piece. The covering piece and the first strip together receive the first deformation member, the intermittent pressing member and the shaking assembly. The first deformation member touches the glass fiber yarns on both sides of the shaking assembly, and the first deformation member receives the glass fiber yarns.

[0013] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the first deformation member includes two connecting members. The connecting members are fixedly connected to the covering piece. The two connecting members are distributed on both sides of the shaking assembly. The connecting member includes a sliding column. The sliding column is connected to the covering piece. The sliding column is movably inserted into the first movable cylinder. The first movable cylinder is rotatably connected to the receiving cylinder. The sliding column clamps the second deformation member. The sliding column is movably connected to the second deformation member. The top of the second deformation member abuts against the covering piece. The tail of the second deformation member abuts against the first movable cylinder. A restraint platform is installed on the sliding column to restrain the position of the first movable cylinder.

[0014] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the receiving cylinders are arranged on both sides of the shaking assembly. The receiving cylinders are movably connected to the glass fiber yarns to enable the surface of the glass fiber yarns to be regularly transported. The second deformation member has a tendency to move in the shrinking direction. The second deformation member pulls the first movable cylinder. The receiving cylinders press against the lower surface of the glass fiber yarns upwards to make them straight, so as to avoid the parts of the glass fiber yarns covering each other.

[0015] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, while the second deformation member always maintains a certain pressure so that the receiving cylinders can always press the glass fiber yarns straight: the second deformation member can contract or expand so that the first movable cylinder can move up and down in the vertical direction on the sliding column, and the receiving cylinders can elastically move within a certain range, so that the glass fiber yarns will not be damaged due to hard obstruction.

[0016] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the intermittent pressing member includes a power member and a rotating wheel. The power member is installed on the covering piece, the covering piece is rotatably connected to the rotating wheel, the rotating wheel is connected to the power member, and two trigger members are installed on the outer periphery of the rotating wheel. The trigger member includes a pressing piece. The trigger members are divided into two columns on the cylindrical surface of the rotating wheel. The two columns of trigger members are located on both sides of the plane bisecting the cylindrical surface of the rotating wheel, and the pressing pieces on the two columns of trigger members are asymmetrically distributed.

[0017] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the power member drives the rotating wheel to rotate, so that the pressing piece rotates with the rotating wheel. Because the pressing pieces are arranged alternately, only one pressing piece acts on the shaking component at the same time. The pressing pieces act on the shaking component alternately, and the shaking component generates regular vibrations. The vibrations of the shaking component drive the glass fiber yarns to shake, so that the glass fiber yarns can be powered to spread out, avoiding overlapping parts of the glass fiber yarns.

[0018] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the glass fiber yarns pass over the upper side of the receiving cylinder and then reach the lower side of the shaking component.

[0019] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the shaking component includes a rectangular member. The rectangular member is located inside the first strip. A connecting piece one is movably connected to the rectangular member. The connecting piece one is rotatably connected to the shaking cylinder. The shaking cylinder is movably connected to the glass fiber yarns. The connecting piece one and the shaking cylinder are arranged alternately. Above the connecting piece one, there are a pressing piece and a deformable member three; the pressing piece abuts against the pressing piece of the trigger member, and the deformable member three is connected to the first strip. The deformable member three changes in length along the axis of the deformable member three.

[0020] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the trigger member is correspondingly connected to the pressing piece. When one pressing piece in one circle of trigger members abuts against the pressing piece, the other circle of trigger members is in a separated state from the pressing piece. The pressing piece drives the connecting piece one to move downward along the rectangular member, and the deformable member three is stressed and elongated. The connecting piece one and the shaking cylinder move downward together, and the part of the glass fiber yarns in this area sags downward; after the pressing piece of this circle is separated from the pressing piece, the deformable member three linked by the pressing piece of this circle forces the connecting piece one to return to its original position, and the glass fiber yarns also return to being straight, during which a shaking occurs; Subsequently, the trigger member of the connecting piece one in the other circle exerts a force on the other pressing piece, causing the shaking cylinder to move downward, so that the glass fiber yarns are shaken again until the deformable member three of this group of linkages forces the connecting piece one to return to its original position, and the glass fiber yarns are shaken repeatedly, causing the overlapping parts of the glass fiber yarns to spread out.

[0021] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the jitter cylinder is misaligned on the first connecting piece, and the glass fiber yarns are not concentratedly squeezed, preventing breakage caused by over-concentration.

[0022] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the pressing piece includes the second connecting piece and the third connecting piece. The second connecting piece is installed on the upper side of the first connecting piece. The included angle between the third connecting piece and the second connecting piece is 90 degrees, and the included angle between the third connecting piece and the axis of the jitter cylinder is 90 degrees.

[0023] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the fourth connecting piece and the fifth connecting piece are installed on the rectangular member. The fourth connecting piece is rotatably connected to the rotating table. Cleaning fibers are installed on the outer periphery of the rotating table. The fifth connecting piece is connected to the power mechanism. The power mechanism is connected to the rotating table through a power transmission mechanism. The axis of the rotating table forms a 90-degree angle with the length direction of the jitter cylinder. A through hole is recessed in the head of the first connecting piece, and the fourth connecting piece and the fifth connecting piece pass through the through hole.

[0024] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the power mechanism controls the rotation of the rotating table by means of a power transmission mechanism. The rotating table drives the cleaning fibers to rotate. The cleaning fibers spread the two side parts of the glass fiber yarns outwards, so that the mutually overlapping parts of the glass fiber yarns are dispersed.

[0025] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the cleaning fibers are made of soft fibers.

[0026] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the through hole restricts the movement range of the fourth connecting piece and the fifth connecting piece, preventing them from interfering with the operation of the first connecting piece.

[0027] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the fourth connecting piece and the fifth connecting piece form a 7-shaped component, which bears the rotating table and the power mechanism and does not interfere with the operation of the jitter cylinder.

[0028] As a preferred technical solution of a device for detecting the sizing on the surface of glass fiber yarns, the power mechanism includes a motor, and the power mechanism includes a reduction box;

[0029] The rotating table and the cleaning fibers are installed at the tail of the rectangular member. The cleaning fibers rotate to smooth the glass fiber yarns, so that the mutually overlapping parts of the glass fiber yarns are dispersed.

[0030] As a preferred technical solution of a device for detecting the surface sizing of glass fiber yarns, the tensioning mechanism includes several assembly tables, on which a deformation member IV is installed. The movable end of the deformation member IV is provided with an adjustment table, which is movably connected to the deformation member IV. Two adjusting rotary rods are arranged on the assembly table, and the adjusting rotary rods are rotationally connected to the adjustment table, and adjacent adjusting rotary rods are staggered from each other.

[0031] As a preferred technical solution of a device for detecting the surface sizing of glass fiber yarns, the deformation member III, the deformation member IV and the deformation member II all include helical beryllium copper wires.

[0032] The infrared absorption spectrum of glass fiber can be used to detect the quality, distribution and thickness information of the surface sizing components on the glass fiber.

[0033] As a preferred technical solution of a device for detecting the surface sizing of glass fiber yarns, the detection principle of infrared spectrum: Infrared spectrum absorbs infrared light of specific wavelengths through molecular vibration to form characteristic absorption peaks.

[0034] The components of the surface sizing include coupling agents and binders, and may contain specific functional groups including silanol groups and amino groups. The position and intensity of their infrared absorption peaks will directly reflect the changes in the chemical bond state. The key index of sizing quality is uniformity: uneven sizing coating will cause fluctuations in the intensity of absorption peaks, and thus the quality information of the surface sizing can be obtained through the detection of infrared spectrum.

[0035] The beneficial effects of a device for detecting the surface sizing of glass fiber yarns according to the present invention: The glass fiber yarn can be quickly and efficiently smoothed by the smoothing component, and the tensioning mechanism tightens and straightens the glass fiber yarn. Through the cooperation of the second cylinder and the first cylinder, the glass fiber yarn can quickly move to below the detection component, facilitating the detection component to move the ATR accessory, stop at any position on the glass fiber, and perform detection. The moving direction of the ATR accessory is perpendicular to the moving direction of the quick movement of the glass fiber yarn, realizing positioning and detection at any position on the plane of the glass fiber yarn without damaging the fiber. The receiving cylinder can elastically move within a certain range, so that the glass fiber yarn will not be damaged due to hard obstruction. The pressing piece alternately acts on the shaking component, and the shaking component generates regular oscillations. The oscillations of the shaking component drive the glass fiber yarn to shake, enabling the glass fiber yarn to have the power to spread it out, avoiding overlapping parts of the glass fiber yarn and avoiding undetected parts.

When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross - sectional views showing the device structure will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three - dimensional spatial dimensions including length, width and depth should be included.

[0056] Such as Figures 1 to 14As shown in the figure, the present invention provides a device for detecting the sizing on the surface of glass fiber yarns, which includes a receiving table 12. On the upper side of the receiving table 12, there are arranged a first long cylinder 13, a detecting member 14, a cutting table 15, a tensioning mechanism 18, a flattening assembly 17, and a second long cylinder 16. The flattening assembly 17 is located in the space between the first long cylinder 13 and the detecting member 14. The flattening assembly 17 flattens the glass fiber yarns, and the tensioning mechanism 18 makes the glass fiber yarns taut and straight.

[0057] The glass fiber yarns are wound around a reel, and the reel is installed on the first long cylinder 13. The glass fiber yarns sequentially pass through the flattening assembly 17, the detecting member 14, the cutting table 15, the tensioning mechanism 18, and the second long cylinder 16;

[0058] The flattening assembly 17 generates vibrations on the glass fiber yarns, so that the glass fiber yarns are free of wrinkles and flattened during the vibrations, avoiding overlapping parts of the glass fiber yarns, and preventing covering and detection dead angles when detecting the glass fiber yarns.

[0059] The first long cylinder 13, the detecting member 14, the cutting table 15, and the second long cylinder 16 are devices that can be adopted in the market. Reels are installed on both the first long cylinder 13 and the cutting table 15, and the glass fiber yarns are wound around the reels.

[0060] A flattening assembly 17 can also be arranged between the tensioning mechanism 18 and the second long cylinder 16.

[0061] The flattening assembly 17 includes a first strip 172, which is installed on the receiving table 12. The lower edge of a covering piece 1734 is arranged with the first strip 172. The lower edge of the covering piece 1734 is provided with a first deformation member 173, an intermittent pressing member 174, and a vibration assembly 175. The intermittent pressing member 174 can force the vibration assembly 175 to move up and down reciprocally, and the vibration assembly 175 alternately drives the glass fiber yarns to vibrate. The first deformation member 173 is located on both sides of the vibration assembly 175 and receives the glass fiber yarns.

[0062] The first strip 172 receives the covering piece 1734, and the covering piece 1734 and the first strip 172 together receive the first deformation member 173, the intermittent pressing member 174, and the vibration assembly 175.

[0063] The first deformation member 173 touches the glass fiber yarns on both sides of the vibration assembly 175, and the first deformation member 173 receives the glass fiber yarns.

[0064] The deformation part 173 includes two connecting parts, which are fixedly connected to the covering piece 1734. The two connecting parts are distributed on both sides of the shaking component 175. The connecting part includes a sliding column 176, which is connected to the covering piece 1734. The sliding column 176 is movably inserted into the first movable cylinder 177, and the first movable cylinder 177 is rotatably connected to the receiving cylinder 178. The sliding column 176 clamps the second deformation part 179, and the sliding column 176 is movably connected to the second deformation part 179. The top of the second deformation part 179 abuts against the covering piece 1734, and the tail of the second deformation part 179 abuts against the first movable cylinder 177. A restraint platform is arranged on the sliding column 176 to restrain the position of the first movable cylinder 177.

[0065] The receiving cylinders 178 are arranged on both sides of the shaking component 175. The receiving cylinders 178 are movably connected to the fiberglass yarn, so that the surface of the fiberglass yarn is carried in a standardized manner. The second deformation part 179 has a tendency to move in the shrinking direction. The second deformation part 179 pulls the first movable cylinder 177, and the receiving cylinder 178 presses upward on the lower surface of the fiberglass yarn to straighten it, preventing the fiberglass yarn from having overlapping parts.

[0066] The second deformation part 179 always maintains a certain amount of pressure so that the receiving cylinder 178 can always press the fiberglass yarn to keep it straight. At the same time, the second deformation part 179 can contract or expand, enabling the first movable cylinder 177 to move back and forth in the vertical direction on the sliding column 176, and the receiving cylinder 178 can elastically move within a certain range, so that the fiberglass yarn will not be damaged due to hard obstacles.

[0067] The intermittent pressing part 174 includes a power part 1710 and a rotating wheel 1721. The power part 1710 is arranged on the covering piece 1734. The covering piece 1734 is rotatably connected to the rotating wheel 1721. The rotating wheel 1721 is connected to the power part 1710. Two trigger parts are arranged on the outer circumference of the rotating wheel 1721. The trigger part includes a pressing piece 1722. The trigger parts are divided into two columns on the cylindrical surface of the rotating wheel 1721. The two columns of trigger parts are located on both sides of the plane that bisects the cylindrical surface of the rotating wheel 1721, and the pressing pieces 1722 on the two columns of trigger parts are asymmetrically distributed.

[0068] The power part 1710 drives the rotating wheel 1721 to rotate, so that the pressing piece 1722 rotates with the rotating wheel 1721. Because the pressing pieces 1722 are arranged alternately, only one pressing piece 1722 acts on the shaking component 175 at the same time. The pressing pieces 1722 act on the shaking component 175 alternately, and the shaking component 175 generates regular oscillations. The oscillations of the shaking component 175 drive the fiberglass yarn to shake, enabling the fiberglass yarn to have the power to spread it out, preventing the fiberglass yarn from having overlapping parts.

[0069] The fiberglass yarn passes over the upper side of the receiving cylinder 178 and then reaches the lower side of the shaking assembly 175.

[0070] The shaking assembly 175 includes a rectangular piece 1723 which is inside the long strip 172. A first connecting piece 1724 is movably connected to the rectangular piece 1723. The first connecting piece 1724 is rotatably connected to a shaking cylinder 1725. The shaking cylinder 1725 is movably connected to the fiberglass yarn. The first connecting piece 1724 and the shaking cylinder 1725 are distributed alternately. Above the first connecting piece 1724, there are arranged a pressing piece 1726 and a third deformable piece 1735. The pressing piece 1726 abuts against the pressing sheet 1722. The third deformable piece 1735 is connected to the long strip 172. The third deformable piece 1735 changes its length along the axis of the third deformable piece 1735.

[0071] The trigger piece is correspondingly connected to the pressing piece 1726. When one of the pressing sheets 1722 in one circle abuts against the pressing piece 1726, the other circle of trigger pieces is in a separated state from the pressing piece 1726. The pressing piece 1726 drives the first connecting piece 1724 to move downward along the rectangular piece 1723. The third deformable piece 1735 is stressed and elongated. The first connecting piece 1724 and the shaking cylinder 1725 move downward together. The part of the fiberglass yarn in this area sags downward. After the pressing sheet 1722 of this circle separates from the pressing piece 1726, the third deformable piece 1735 linked by the pressing sheet 1722 of this circle forces the first connecting piece 1724 to return to its original position, and the fiberglass yarn also returns to being straight, during which a shaking occurs once. Subsequently, the trigger piece of the first connecting piece 1724 in the other circle applies a force to another pressing piece 1726, causing the shaking cylinder 1725 to move downward, thus applying a shaking effect to the fiberglass yarn again until the third deformable piece 1735 of this set of linkage forces the first connecting piece 1724 to return to its original position, and the fiberglass yarn is shaken repeatedly, causing the overlapping parts of the fiberglass yarn to spread out.

[0072] The shaking cylinder 1725 is arranged out of position on the first connecting piece 1724, and the extrusion on the fiberglass yarn is not concentrated, preventing breakage caused by over - concentration.

[0073] The pressing piece 1726 includes a second connecting piece 1727 and a third connecting piece 1728. The second connecting piece 1727 is arranged on the upper side of the first connecting piece 1724. The included angle between the third connecting piece 1728 and the second connecting piece 1727 is 90 degrees. The included angle between the third connecting piece 1728 and the axis of the shaking cylinder 1725 is 90 degrees.

[0074] The connecting piece four 1729 and the connecting piece five 1730 are installed on the rectangular piece 1723. The connecting piece four 1729 is rotatably connected to the rotating table 1731. The cleaning fibers 1732 are installed on the outer periphery of the rotating table 1731. The connecting piece five 1730 is connected to the power mechanism. The power mechanism is connected to the rotating table 1731 through the power transmission mechanism. The axis of the rotating table 1731 forms a 90-degree angle with the length direction of the shaking cylinder 1725. A through hole 1733 is recessed in the head of the connecting piece one 1724, and the connecting piece four 1729 and the connecting piece five 1730 pass through the through hole 1733.

[0075] The power mechanism controls the rotation of the rotating table 1731 by using the power transmission mechanism. The rotating table 1731 drives the cleaning fibers 1732 to rotate. The cleaning fibers 1732 spread the two side parts of the glass fiber yarn outwards, so that the mutually covered parts of the glass fiber yarn are dispersed.

[0076] The cleaning fibers 1732 are made of soft fibers. The through hole 1733 restricts the movement range of the connecting piece four 1729 and the connecting piece five 1730 to avoid interfering with the operation of the connecting piece one 1724.

[0077] The connecting piece four 1729 and the connecting piece five 1730 form a 7-shaped component, which bears the rotating table 1731 and the power mechanism and does not interfere with the operation of the shaking cylinder 1725.

[0078] The power mechanism includes a motor, and the power mechanism includes a reduction box.

[0079] The rotating table 1731 and the cleaning fibers 1732 are installed at the tail of the rectangular piece 1723. The cleaning fibers 1732 rotate to smooth the glass fiber yarn, so that the mutually covered parts of the glass fiber yarn are dispersed.

[0080] The tensioning mechanism 18 includes several assembly platforms 182. The deformation piece four 183 is installed on the assembly platform 182. The adjustment platform 184 is installed at the movable end of the deformation piece four 183. The adjustment platform 184 is movably connected to the deformation piece four 183. Two adjusting rotating rods 185 are arranged on the assembly platform 182. The adjusting rotating rods 185 are rotatably connected to the adjustment platform 184, and the adjacent adjusting rotating rods 185 are staggered from each other.

[0081] The deformation piece three 1735, the deformation piece four 183 and the deformation piece two 179 all include spiral beryllium copper wires.

[0082] The infrared absorption spectrum of glass fiber can be used to detect the quality, distribution and thickness information of the surface sizing components on the glass fiber.

[0083] The detection principle of infrared spectrum Infrared spectrum absorbs infrared light of specific wavelengths through molecular vibration to form characteristic absorption peaks.

[0084] The composition of the surface sizing material includes coupling agents and binders, and may contain specific functional groups including silanol groups and amino groups. The positions and intensities of their infrared absorption peaks will directly reflect the changes in chemical bond states. The key index of the sizing material quality is uniformity: uneven coating of the sizing material will cause fluctuations in the absorption peak intensity, and thus the quality information of the surface sizing material can be obtained through the detection of infrared spectroscopy.

[0085] Using the ATR attenuated total reflection infrared spectroscopy technology, the surface sizing material layer can be directly tested without destroying the sample.

[0086] If the sizing material layer is thin, the spatial resolution can be improved by micro-area infrared spectroscopy to locate local defects.

[0087] Key points of data analysis - characteristic peak comparison: For example, if the characteristic peak of the Si-O-Si bond of the silane coupling agent shifts or splits, it may indicate hydrolysis of the coupling agent or poor bonding with the fiber.

[0088] Quantitative analysis: Calculate the concentration changes of the key components in the sizing material through the absorption peak intensity, and verify the results by combining with thermogravimetric analysis TGA.

[0089] The ATR accessory 1 includes the ATR zinc selenide crystal of the infrared spectrometer.

[0090] An inner side of the detection piece 14 is recessed with a working cavity, and a detection mechanism is arranged in the working cavity. The detection mechanism includes the ATR accessory 1, the infrared spectrometer 2, the movable table 3, the pressing table 4, the movable groove 5, the first lead screw 6 and the hanging table 9. The movable grooves 5 are recessed on the upper and lower sides of the working cavity. The first lead screw 6 is rotatably connected in the movable groove 5. The first lead screw 6 on the upper side of the detection piece 14 is threaded with the hanging table 9. The movable table 3 is arranged on the hanging table 9. The pressing table 4 is arranged at the movable end of the movable table 3. The first lead screw 6 on the lower side of the detection piece 14 is threaded with the infrared spectrometer 2. The ATR accessory 1 is arranged on the upper side of the infrared spectrometer 2. A walking control mechanism is connected between the two first lead screws 6;

[0091] A walking control mechanism is arranged on one side of the detection mechanism. The walking control mechanism includes a transmission belt 8, a first transmission column 20, a guiding block 21 and a driving wheel 22. The first lead screw 6 on the lower side of the detection piece 14 is connected to the rotating column of the servo motor 1 7. The two first lead screws 6 are both provided with driving wheels 22. The first transmission columns 20 are arranged in an array on the outer periphery of the driving wheels 22. The guiding block 21 is arranged on the first transmission column 20. The guiding block 21 is made of an elastic material. Two transmission belts 8 are connected between the two driving wheels 22. A deformation layer 23 is connected between the two transmission belts 8. A precision bonding part is arranged on the outer side of the deformation layer 23. The precision bonding part can be closely clamped between the two first transmission columns 20;

[0092] The precision bonding part can reduce the transmission error and make the ATR accessory 1 and the pressing table 4 more accurately correspond;

[0093] The precision coupling includes a deformation layer 23, a steel ring 24, a first transmission column 25, a first connecting piece 26, a shaping layer 27 and a second connecting piece 28. The first transmission column 25 is externally hoop-shaped with the shaping layer 27. The shaping layer 27 is externally connected to the steel ring 24. The steel ring 24 is an elastic metal sheet. The two sides of the steel ring 24 are respectively provided with the first connecting piece 26. The upper side of the steel ring 24 is provided with the second connecting piece 28. The steel ring 24 is inserted into the first transmission column 25. The first connecting piece 26 is inserted into the first transmission column 25. The deformation layer 23 is fixedly connected to the outside of the steel ring 24. The material of the deformation layer 23 is nitrile rubber.

[0094] When the precision coupling is stuck between two first transmission columns 20, the precision coupling tightly presses the two adjacent first transmission columns 20 on both sides, so that during power transmission, power loss is reduced and the rotation angle difference between the two power wheels 22 is reduced, thereby greatly reducing the position difference between the pressing table 4 and the ATR accessory 1. The fiberglass yarn pauses operation, the pressing table 4 and the ATR accessory 1 move to a certain position, the movable table 3 controls the pressing table 4 to move downward, the pressing table 4 squeezes the fiberglass yarn onto the ATR accessory 1, and the infrared spectrometer 2 and the ATR accessory 1 operate to collect the infrared parameters of the fiberglass yarn.

[0095] The existing technology can be modified by replacing the pressing part of the infrared spectrometer with a movable pressing table 4. The pressing part includes a pressing screw.

[0096] The specific implementation method is as follows: The fiberglass yarn is wound around the reel on the first long cylinder 13. The fiberglass yarn sequentially passes through the flattening assembly 17, the detection part 14, the cutting table 15 and the tensioning mechanism 18 and reaches the reel on the second long cylinder 16. The second long cylinder 16 is connected to the winding motor. When the winding motor is started, the reel on the second long cylinder 16 winds the fiberglass yarn.

[0097] Inside the flattening assembly 17, the fiberglass yarn passes over the upper side of the receiving cylinder 178, then reaches the lower side of the shaking assembly 175 and then reaches the upper side of the receiving cylinder 178. The second deformable part 179 always maintains a certain pressure so that the receiving cylinder 178 can always press the fiberglass yarn to make it straight. At the same time, the second deformable part 179 can contract or expand, enabling the movable cylinder 177 to move up and down in the vertical direction on the sliding column 176. The pressing piece 1722 alternately acts on the shaking assembly 175, and the shaking assembly 175 generates regular oscillations. The oscillations of the shaking assembly 175 drive the fiberglass yarn to shake, so that the fiberglass yarn has the power to spread it out and avoid the overlapping parts of the fiberglass yarn.

[0098] It should be understood that, in the development of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without undue experimentation, such development efforts will be routine work of design, fabrication, and production.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
