Description
Technical Field
[0001] The present invention relates to the technical field of glue fluidity detection, and particularly relates to a processing technology and sampling detection device for steel nail glue. Background Art
[0002] During the production of glue for steel nails, the fluidity of the glue is directly related to its coating uniformity and actual use performance, and is one of the important indicators for measuring product quality. Especially during continuous and batch production, how to achieve real-time detection and dynamic monitoring of the glue fluidity is of great significance for ensuring product stability.
[0003] Most traditional fluidity detection methods use manual sampling and send the samples to the laboratory for measurement by methods such as the flow cup method and the flow time method. This method not only has cumbersome steps and a long detection cycle, but also often has problems such as detection lag and inability to reflect the real-time state of production, which easily leads to unqualified products flowing into subsequent processes.

[0033] In summary, the present invention mainly has the following beneficial effects:
[0034] In this application, a synthesis tank is arranged in the processing box, and the driving component drives the mixing blade to efficiently mix various glue raw materials, enabling the full reaction and uniform synthesis of the glue. The provided sampling component can intermittently extract glue samples from the synthesis tank during the mixing process and send them into the defoaming tube for rotation and tremor defoaming, effectively removing the bubbles in the samples and improving the accuracy of the fluidity detection. After being processed, the samples drip onto the inclined detection plate and flow naturally along the dispensing film covering its surface. The fluidity of the glue can be visually judged through the scale mark. In addition, the upper and lower reels drive the film to be replaced, and the frame structure scrapes off the residual glue, ensuring that each detection is carried out on a clean film surface, avoiding contamination and misjudgment. This application can continuously and automatically complete the sampling, defoaming, and fluidity detection of the glue without interrupting production, with the characteristics of compact structure, strong linkage, and simple operation. It is particularly suitable for the real-time monitoring and quality assurance of product status in continuous and batch glue production lines, solving the problems of detection lag and inability to reflect the real-time production status in the existing technology.

[0061] An anti-foaming tube 110 provided on the sampling tube 106, communicated with the sampling tube 106;
[0062] A driving component disposed between the synthesis tank 101 and the mixing blade 102, for driving the mixing blade 102 to rotate;
[0063] A sampling component disposed between the processing box body 100 and the sampling pipe 106, for intermittently extracting a part of the liquid onto the dispensing film 104 through the sampling pipe 106 when the driving component drives the mixing blade 102 to rotate;
[0064] A winding component disposed between the sampling component and the reel 107, for rotating one of the lower reels 107 when the sampling component extracts the liquid in the synthesis tank 101, and the winding component can stop rotating one of the lower reels 107 when the sampling component conveys the liquid onto the dispensing film 104;
[0065] Wherein, the sampling component can extract a preset amount a of liquid into the defoaming pipe 110 and rotate the defoaming pipe 110 for a preset time a1;
[0066] Wherein, the defoaming pipe 110 can vibrate when rotating to help the bubbles overflow;
[0067] By setting the synthesis tank 101, various basic raw materials for preparing the steel nail glue are first added into the synthesis tank 101 disposed in the processing box body 100 in sequence. The synthesis tank 101 constitutes the core reaction area of the device, and a mixing blade 102 is arranged inside it. The mixing blade 102 continuously rotates driven by the driving component, for efficiently stirring and mixing the raw materials.
[0068] The raw materials are put into the synthesis tank 101 in the order and proportion set by the process. After the driving component is started, it drives the mixing blade 102 to rotate at a high speed. During the stirring process, through the comprehensive actions of shearing, flipping, turbulent flow, etc. of the mixing blade 102, various raw materials fully contact and react in the synthesis tank 101 to form a high-performance glue in a physically homogeneous or partially chemically cross-linked state.
[0069] Specifically, in order to monitor the fluidity state of the glue in real time, the detection component in the device is activated to start the sampling operation. The sampling component is arranged between the processing box body 100 and the synthesis tank 101 and is communicated with the sampling pipe 106 on the side wall of the synthesis tank 101. The outlet of the sampling pipe 106 is oriented towards the position of the detection plate 103 on one side of the processing box body 100, and a part of the glue can be extracted from the tank without affecting the overall mixing process. The sampling process is intermittent. During the rotation of the mixing blade 102, a preset amount a of glue sample is extracted into the defoaming pipe 110. The extracted glue flows out through the sampling pipe 106 and drops onto the surface of the glue-dropping film 104 located on the detection plate 103. The detection plate 103 is an inclined structure that can be rotated. Its upper surface is covered with a replaceable glue-dropping film 104, and at the same time, scale marks 105 for calibrating the fluidity distance are provided. After the glue drops on the film, it naturally flows along the inclined direction under the action of gravity, and physical parameters such as the flow length, flow mark width, or flow time formed on the film surface can all be used as important bases for evaluating its fluidity.
[0070] To achieve continuous detection, one end of the glue-dropping film 104 is wound around the upper reel 107 above the detection plate 103, and the other end is connected to the lower reel 107 below the detection plate 103. After each sampling and detection is completed, the driving and winding component drives the lower reel 107 to rotate, pulling the glue-dropping film 104 to slide, so that the film piece with attached glue is rolled away, and a new clean film surface is simultaneously unfolded to prepare for receiving the dripping of the next round of samples.
[0071] In order to prevent the glue residue on the film surface from affecting the subsequent detection results, a frame a108 and a frame b109 are respectively arranged at one end and the middle of the detection plate 103. When the glue-dropping film 104 passes between the two, it will be properly limited, and at the same time, the frame edge plays a scraping role, effectively cleaning the glue residue and ensuring the cleanliness and consistency of the detection surface. The winding process is that the lower reel 107 performs the winding operation, and the reel 107 above the detection plate 103 simultaneously releases the glue-dropping film 104, so that the film slides forward along the surface of the detection plate 103. During the process of the film passing through the upper surface of the detection plate 103, it successively passes through the frame a108 and the frame b109 arranged at one end and the middle of the detection plate 103, and the frame edge scrapes the glue residue on its surface, so as to ensure that the surface of the film wound on the lower reel 107 remains clean, avoiding contamination and adhesion. After all the glue-dropping film 104 on the upper reel 107 is released, the operator can replace the upper and lower reels 107, that is, replace the used film wound below to the upper part, and reload a new clean film onto the lower reel 107 to continue the subsequent fluidity detection cycle operation and realize the recyclable replacement use of the whole set of films.
[0072] In addition, to further improve the accuracy of glue detection and avoid interference of bubbles generated during the mixing process on the fluidity measurement results, an anti-foaming tube 110 is provided on the sampling tube 106 path of this device, which is used for defoaming the extracted glue sample. When the sampling component extracts a part of the glue from the synthesis tank 101, the glue first enters the anti-foaming tube 110.
[0073] Set the extracted volume to the preset amount a, and after the sample enters the anti-foaming tube 110, make it rotate at a preset speed, and the rotation duration is set to the preset time a1. During the rotation of the anti-foaming tube 110, the glue inside undergoes rapid stratification under the action of centrifugal force, and the tiny bubbles in the glue liquid quickly float to the surface due to their lower density, thus effectively detaching from the glue body. To enhance the defoaming efficiency, the anti-foaming tube 110 also undergoes intermittent tremor movement during rotation, whose function is to further disturb the glue structure, prompt some bubbles attached inside the glue liquid or on the tube wall to quickly desorb and release, thereby significantly improving the defoaming effect.
[0074] After the rotation and tremor processes are completed, the glue that has completed the defoaming treatment is continuously transported to the surface of the glue-dropping film 104 on the detection plate 103 to participate in the fluidity detection. This process not only effectively eliminates the problem of misjudgment of the flow distance caused by bubble residues, but also avoids the errors caused by stirring residual bubbles in traditional manual detection, making the detection data more real-time and reliable.
[0075] In summary, this application effectively solves the technical problem that real-time, accurate, and automatic fluidity detection cannot be achieved in the existing glue production, can realize the real-time control of the glue state during the glue production process, and is suitable for the detection requirements in continuous production.
[0076] As a further solution of the present invention, the driving component includes a motor 200 connected to the processing box body 100. The driving shaft of the motor 200 extends to the top of the synthesis tank 101 and is connected with a mixing shaft 201, and the mixing shaft 201 extends into the synthesis tank 101 and is connected with the mixing blades 102 inside it;
[0077] By setting the motor 200 to drive the rotation of the mixing shaft 201, the mixing blades 102 can efficiently stir various glue raw materials in the synthesis tank 101 to ensure sufficient reaction between the raw materials and generate high-quality glue products. During the mixing process, the shear force and fluid disturbance generated by the rotation of the mixing blades 102 can effectively break the interfacial tension between the raw materials, improve the uniformity and reactivity of each component, and thus enhance the bonding force and fluidity of the glue.
[0078] As a further solution of the present invention, the sampling component includes a piston 300 disposed in the defoaming tube 110. A connection opening 301 is formed in the defoaming tube 110, and a connection ring 302 is rotatably connected in the connection opening 301. The sampling tube 106 includes a suction tube 303 and a release tube 304. One end of the suction tube 303 communicates with the side wall of the synthesis tank 101, and the other end communicates with the connection ring 302. One end of the suction tube 303 communicates with the connection ring 302, and the other end passes through the processing box body 100 and extends above the detection plate 103, with the outlet facing the dispensing film 104. Check valves 305 are provided on both the suction tube 303 and the release tube 304. The check valve 305 on the suction tube 303 is used for liquid to enter the defoaming tube 110, and the check valve 305 on the release tube 304 is used for liquid to flow out of the defoaming tube 110;
[0079] By providing the piston 300, the piston 300 can reciprocate in the defoaming tube 110. When the piston 300 moves upward in the defoaming tube 110, a negative pressure will be generated. At this time, the check valve 305 on the suction tube 303 opens and the check valve 305 on the release tube 304 closes, and the liquid is under the negative pressure. Initially, the liquid flows in the suction tube 303 and flows into the defoaming tube 110. When the piston 300 moves downward in the defoaming tube 110, a positive pressure will be generated. At this time, the check valve 305 on the release tube 304 opens and the check valve 305 on the suction tube 303 closes, prompting the liquid to be able to drip onto the dispensing film 104 through the release tube 304. After the liquid drops onto the surface of the dispensing film 104, the glue will naturally flow along the inclined surface of the film to form a flow trace. By detecting the flowing distance, width and time of the liquid on the film, the fluidity and viscosity of the glue can be evaluated in real time, thereby providing important data for subsequent quality control. By using the limited up and down movement distance of the piston 300 and the limited capacity of the defoaming tube 110, the amount of glue extracted each time can be limited to a certain amount. By accurately setting the up and down movement range of the piston 300 and the volume of the defoaming tube 110, it can be ensured that the amount of glue extracted from the synthesis tank 101 each time is predetermined, avoiding the extraction of too much or too little sample, and ensuring the consistency and repeatability of each sampling. Among them, the check valve 305 can be a diaphragm check valve. This check valve 305 is designed to be automatically opened and closed under the action of negative pressure and positive pressure. When negative pressure acts on the suction tube 303, the diaphragm will be attracted to the open position, enabling the liquid to flow into the defoaming tube 110 through the suction tube 303; when positive pressure acts, the diaphragm will be pushed to the closed position to prevent the liquid from flowing backward. At the same time, the check valve 305 on the release tube 304 will work automatically according to the pressure change, remaining closed when negative pressure exists and opening when positive pressure acts, ensuring that the liquid only flows out of the release tube 304. This check valve 305 can ensure that when extracting glue, the glue only flows in the specified direction.
[0080] As a further solution of the present invention, the sampling component further includes a central shaft 306 connected inside the defoaming pipe 110. A chute 307 is provided on the central shaft 306. The piston 300 is slidably connected to the chute 307. A lead screw 308 threadedly connected to the piston 300 is rotatably connected to the central shaft 306. The top of the lead screw 308 extends to the top of the defoaming pipe 110. A gear a 309 is connected to the mixing shaft 201. A bracket 310 for supporting the synthesis tank 101 is connected inside the processing box 100. A transmission shaft 311 is connected to the bracket 310. A connecting shaft 312 is rotatably connected to the synthesis tank 101. A gear b 313 meshing with the gear a 309 is connected to the connecting shaft 312. The gear a 309 is an incomplete gear. A spring a 314 is connected between the connecting shaft 312 and the synthesis tank 101. A transmission chain a 315 is connected between the connecting shaft 312 and the transmission shaft 311. A transmission chain b 316 is connected between the lead screw 308 and the transmission shaft 311;
[0081] By setting the sliding groove 307, the sliding groove 307 opened on the central shaft 306 is slidably connected to the piston 300, enabling the piston 300 to move axially along the defoaming tube 110. Through the rotation of the lead screw 308, the piston 300 can perform precise up and down movements within the defoaming tube 110. The top of the lead screw 308 extends to the top of the defoaming tube 110, so that the position of the piston 300 can be controlled by rotating the lead screw 308, thereby realizing the extraction and release of glue. Under the rotation of the lead screw 308, the up and down movement of the piston 300 can precisely control the amount of glue extracted and released each time. By setting the gear a 309, the gear b 313, the transmission shaft 311, the transmission chain a 315 and the transmission chain b 316, intermittent driving of the synthesis tank 101 and the sampling component can be achieved. Specifically, when the motor 200 drives the mixing shaft 201 to rotate, the gear a 309 can be rotated to mesh with the gear b 313, causing the connecting shaft 312 to rotate. The rotation of the connecting shaft 312 can cause the transmission shaft 311 to rotate through the transmission chain a 315. The rotation of the transmission shaft 311 can cause the lead screw 308 to rotate synchronously through the transmission chain b 316, and then the piston 300 can be moved upward to extract liquid into the defoaming tube 110. When the above-mentioned connecting shaft 312 rotates, the spring a 314 can be twisted to generate potential energy. When the gear a 309 rotates a preset angle, its characteristics as an incomplete gear can be used to disengage from the gear b 313. At this time, the spring a 314 releases potential energy, causing the connecting shaft 312 to perform a reset rotation movement, and then the piston 300 can be moved downward through the above-mentioned transmission mechanism, and the glue can be discharged from the release tube 304 by positive pressure. By setting the above transmission structure, precise control of the piston 300 can be achieved, thereby ensuring that the process of glue extraction and release can be carried out efficiently and intermittently. In addition, when the rotation angles of the connecting shaft 312 and the gear b 313 are limited, by adding the transmission shaft 311, the rotation speed ratio between the lead screw 308 and the connecting shaft 312 can be effectively adjusted. The transmission shaft 311 can help amplify the rotation amplitude of the connecting shaft 312, enabling the lead screw 308 to perform more rotation cycles. This is achieved by adapting an appropriate speed ratio to maximize the use of the limited rotation range of the connecting shaft 312, allowing the lead screw 308 to complete more actions in a short time, thereby ensuring that the piston 300 can perform precise extraction and release operations.
[0082] As a further solution of the present invention, the sampling component further includes a wedge-shaped groove 400 opened at the top of the defoaming tube 110. A positioning ring 401 located at the top of the defoaming tube 110 is slidably connected to the bottom of the bracket 310. A wedge-shaped strip 402 adapted to the wedge-shaped groove 400 is slidably connected to the positioning ring 401. A spring b 403 is connected between the wedge-shaped strip 402 and the positioning ring 401. A slide rail 404 is connected to the inner wall of the positioning ring 401. A lifting rod 405 slidably engaged with the slide rail 404 is slidably connected to the defoaming tube 110. A spring c 406 is connected between the lifting rod 405 and the defoaming tube 110. A ball 407 contacting the slide rail 404 is provided on the lifting rod 405;
[0083] By setting the wedge bar 402 and the wedge groove 400, the cooperation between the wedge bar 402 and the wedge groove 400 can form a ratchet structure. When the transmission shaft 311 drives the lead screw 308 to rotate through the transmission chain b316, the rotation of the lead screw 308 pushes the piston 300, which is threadedly connected thereto, to move linearly upward. At this time, the upward movement of the piston 300 can draw the liquid in the synthesis tank 101 into the defoaming pipe 110, thereby realizing the process of drawing the liquid. At this time, the upward movement of the piston 300 is directly affected by the rotation of the lead screw 308. Once the piston 300 reaches the position of the lifting rod 405, since the top end of the piston 300 contacts the lifting rod 405, the lifting rod 405 will be subjected to an upward pressure, driving the positioning ring 401 and the wedge bar 402 connected thereto to move together. The movement of the lifting rod 405 will cause the wedge bar 402 to disengage from the wedge groove 400. At this time, the mutual cooperation between the wedge bar 402 and the wedge groove 400 fails and no longer plays a fixing role. Therefore, although the upward movement of the piston 300 is limited by space, since the lead screw 308 is still in the transmission state, the lead screw 308 will continue to rotate. Due to the connection between the lead screw 308 and the piston 300, when the lead screw 308 continues to rotate, the piston 300 will not only move along the axis of the defoaming pipe 110, but also drive the defoaming pipe 110 to rotate. Specifically, when the piston 300 touches the lifting rod 405 and causes the wedge bar 402 to disengage from the wedge groove 400, the piston 300 and the defoaming pipe 110 as a whole will be driven by the lead screw 308 and rotate. During the rotation of the defoaming pipe 110, the liquid carried inside it (i.e., the drawn glue) will also perform a circular motion around the central axis 306. As the rotational speed increases, the bubbles entrained in the liquid will be subjected to a centrifugal force much smaller than that of the liquid part due to their density being much smaller than that of the liquid. The liquid will rapidly gather towards the inner wall of the defoaming pipe 110 under the action of the centrifugal force, while the relatively lighter bubbles will be forced to separate from the liquid body and gather in the central axis region of the defoaming pipe 110. This process can significantly accelerate the separation and release of bubbles in the glue, thereby realizing efficient centrifugal defoaming treatment and providing a more stable sample quality for subsequent glue detection. This process can achieve automatic, continuous, and efficient sampling and defoaming using the original transmission mechanism without the need for external dedicated defoaming equipment.
[0084] In addition, by setting the wedge groove 400 and the wedge bar 402, a ratchet structure with a direction-limiting function is formed in terms of structure. This structure can limit the rotation of the defoaming pipe 110 at a specific stage, thereby precisely controlling the working rhythm of the sampling component.
[0085] Specifically, due to the certain viscosity of the glue, if the piston 300 is directly driven by the lead screw 308 to rotate, due to the viscous resistance inside the liquid, the piston 300 and the defoaming tube 110 may enter the rotating state prematurely, and the predetermined operation sequence of "first extraction and then rotation" cannot be achieved, resulting in insufficient extracted glue volume or unstable centrifugal defoaming effect.
[0086] To solve the above problems, the wedge bar 402 is tightly fitted with the wedge groove 400 before being lifted, constituting a rotational limit for the defoaming tube 110, so that in the initial rotation stage of the lead screw 308, only the piston 300 is driven to move linearly upward along the central axis 306 to achieve quantitative extraction of the glue. When the piston 300 moves upward to the set position and touches the lifting rod 405, the lifting rod 405 drives the positioning ring 401 and the wedge bar 402 to move upward, causing the wedge bar 402 to disengage from the wedge groove 400 and releasing the rotational restriction on the defoaming tube 110. At this time, the lead screw 308 continues to rotate. Since the piston 300 cannot continue to move linearly due to space limitation, it drives the entire defoaming tube 110 to start rotating at high speed, thus completing the centrifugal defoaming operation.
[0087] Therefore, the ratchet structure formed by the wedge bar 402 and the wedge groove 400 not only realizes precise control of the rotation timing of the defoaming tube 110, but also ensures that the two steps of extraction and centrifugation are carried out in sequence under the condition of high glue viscosity, which is the key to the reliable and efficient sampling and defoaming treatment of this structure.
[0088] As a further solution of the present invention, wherein, the defoaming tube 110 can vibrate during rotation to help the bubbles overflow;
[0089] A sleeve 408 sleeving the outer wall of the defoaming tube 110 is connected to the side wall of the processing box body 100. A vibrating bar 409 is slidably connected inside the sleeve 408. A spring d410 is connected between the vibrating bar 409 and the sleeve 408. A plurality of vertical bars 411 with a right trapezoidal cross-section are connected to the outer wall of the defoaming tube 110, and there is a vibrating bar 409 between every two vertical bars 411;
[0090] By setting the vibrating bar 409, during the rotation of the defoaming tube 110, a plurality of vertical bars 411 with a right trapezoidal cross-section provided on its outer wall are evenly distributed at a set pitch, and there is a vibrating bar 409 between every two vertical bars 411. When the defoaming tube 110 rotates at a certain speed, the vertical bars 411 periodically impact the vibrating bar 409, causing the vibrating bar 409 to be forced to compress the spring d410 along its sliding direction.
[0091] As the defoaming tube 110 continues to rotate, the vertical strip 411 quickly detaches after coming into contact with the vibrating strip 409. At this time, the vibrating strip 409 instantaneously rebounds under the action of the spring d410, generating a continuous recoil force on the outer wall of the defoaming tube 110. This effect forms a stable "pulsating vibration effect", causing the defoaming tube 110 to vibrate slightly while rotating at high speed, enhancing the disturbance effect during the centrifugation process.
[0092] The setting of this vibrating structure can effectively break the problem of bubble retention caused by high glue viscosity, enabling the tiny bubbles pushed to the liquid surface or edge by the centrifugal force to quickly overflow or disperse. It is especially suitable for glue systems containing high molecular thickeners or generating microbubbles during the reaction, improving the overall defoaming efficiency and sample homogeneity.
[0093] In addition, the cooperation between the vibrating strip 409 and the vertical strip 411 can also form a ratchet structure. When the drive shaft 311 is driven by the connecting shaft 312 to rotate the defoaming tube 110 by a preset number of turns, that is, after rotating the defoaming tube 110 for a preset time a1, the gear a309 disengages from the gear b313. At this time, the connecting shaft 312 rotates reversely under the drive of the spring a314, driving the drive shaft 311 to rotate for reset. During this process, due to the presence of multiple right-angled trapezoidal vertical strips 411 on the outer wall of the defoaming tube 110, after cooperating with the vibrating strip 409, the backward movement of the vertical strip 411 is not allowed. This restricts the reverse rotation of the defoaming tube 110. At this time, the lead screw 308 is still receiving the reverse rotation drive of the connecting shaft 312 and the drive shaft 311. Since the piston 300 is threadedly connected to the lead screw 308, during the reverse rotation of the lead screw 308, the piston 300 is driven to move downward, realizing a reset linear downward pressing action.
[0094] Due to the reverse rotation of the defoaming tube 110 being restricted by the above-mentioned ratchet structure and unable to continue rotating, the lead screw 308 only drives the piston 300 to move downward during rotation without causing the defoaming tube 110 to rotate accordingly, thus ensuring the stability and linearity of the compression process. During the downward movement of the piston 300, the internal space of the defoaming tube 110 is compressed, thereby applying a positive pressure to the internal glue. At this time, the one-way valve 305 on the extraction tube 303 closes due to the pressure direction, while the one-way valve 305 on the release tube 304 opens under the positive pressure, causing the glue to be quantitatively pressed from the defoaming tube 110 into the release tube 304 and finally dripping onto the dispensing film 104 through the outlet of the release tube 304.
[0095] In this way, the amount of liquid dropped each time can be precisely controlled, and combined with the rotating defoaming step, effectively avoiding the mixing of bubbles into the test glue, improving the repeatability and reliability of the test process. The entire set of mechanisms achieves a high degree of coordination in terms of structural linkage, action rhythm, and fluid control, effectively adapting to the dynamic sampling and application requirements of viscous glue.
[0096] As a further solution of the present invention, the winding component includes a support bar 500 connected to the processing box body 100. A spring rod 501 is rotatably connected to the support bar 500. One end of the spring rod 501 is connected with a limit card 502. A limit card slot 503 which is slidably matched with the limit card 502 is arranged on one side of the reel 107.
[0097] By arranging the support bar 500 and the spring rod 501 rotatably connected thereto, the spring rod 501 has the ability of automatic reset under the elastic action. A limit card 502 which can be inserted into the limit card slot 503 is arranged at one end of the spring rod 501. When the reel 107 is installed in place, the limit card 502 can automatically embed into the limit card slot 503 on the side of the reel 107, so as to realize the accurate limit and fixation of the axial position of the reel 107 and prevent it from axially slipping or loosening during the working process. When it is necessary to replace the reel 107, only need to manually pull out the limit card 502 from the limit card slot 503, and the quick disassembly and replacement of the reel 107 can be realized. The whole structure is simple and compact, which is convenient for operation and maintenance.
[0098] As a further solution of the present invention, the winding component can stop the rotation of one of the lower reels 107 when the sampling component conveys liquid onto the drip glue film 104.
[0099] The winding component includes a worm 504 arranged on the transmission shaft 311. A worm gear 505 which is meshed with the worm 504 is connected to a spring rod 501 arranged on one side of one of the lower reels 107. A ratchet mechanism 506 is arranged between the worm 504 and the transmission shaft 311.
[0100] By arranging the meshing structure of the worm 504 and the worm gear 505, when the transmission shaft 311 rotates, it can drive the worm 504 to rotate synchronously, so as to drive the worm gear 505 and the reel 107 connected thereto to rotate, and realize the winding of the drip glue film 104. When the sampling component is in the extraction stage, that is, when the lead screw 308 drives the piston 300 to move upward to extract liquid, the transmission shaft 311 rotates forward, the worm 504 also rotates forward, and drives the reel 107 to rotate synchronously through the worm gear 505, and winds up the used drip glue film 104.
[0101] During the liquid release stage, that is, when the piston 300 moves downward driven by the reverse rotation of the lead screw 308 and the liquid drips from the release pipe 304 onto the dispensing film 104, the transmission shaft 311 rotates in the reverse direction. At this time, the ratchet mechanism 506 provided between the transmission shaft 311 and the worm 504 will prevent the reverse rotation of the worm 504, thereby stopping the rotation of the worm gear 505 and the reel 107. Since the worm 504 and the worm gear 505 have a self-locking function, it is ensured that during the liquid dripping process, the dispensing film 104 remains stationary, which is conducive to the stable adhesion and uniform diffusion of the liquid on the film surface, and avoids the deviation of the dripping position or uneven glue coating caused by the movement of the film surface. Therefore, through the cooperation of the ratchet and the worm gear 505 and the worm 504, not only the precise coordination of the glue extraction and release processes is achieved, but also a new and clean area of the dispensing film 104 can be obtained by winding before each detection, ensuring the accuracy and repeatability of the detection results.
[0102] As a further aspect of the present invention, a support bar 111 is connected to one side of the processing box 100, the detection plate 103 is rotatably connected to the support bar 111, and a positioning bolt 112 is threadedly connected to the support bar 111, and one end of the positioning bolt 112 presses against the detection plate 103;
[0103] Through the above settings, by rotating the positioning bolt 112, its front end presses against the detection plate 103 to prevent it from shaking or shifting during use, ensuring that the detection plate 103 maintains a stable posture during glue dripping, spreading, and detection and analysis.
[0104] In addition, the angle of the detection plate 103 can also be adjusted to change the inclination of the dispensing film 104. The fluidity of the glue is greatly affected by gravity. Changing the angle can change the direction of the gravity action, causing the flow pattern of the glue on the surface to change. When the angle of the detection plate 103 is large, the influence of gravity on the glue is more obvious. Especially for low-viscosity and high-fluidity glue, the gravity action can make it flow more easily. When the angle is small, the driving force of gravity on the glue is small. For high-viscosity and low-fluidity glue, it can make it stagnate or flow slowly at a small angle, thus simulating its performance in the actual use environment.
[0105] A steel nail glue processing process, using the steel nail glue processing and sampling detection device described in any one of the above, includes the following steps:
[0106] Step 1: Add raw materials to the synthesis tank 101 in sequence. The raw materials include basic polymer components: polyvinyl acetate emulsion 48%-60%, epoxy resin 12%-15%, and waterborne polyurethane 6%-10%;
[0107] It also includes: 0.5%-1.5% of hydroxyethyl cellulose, 0.1%-0.5% of carbomer, 2%-5% of isocyanates, 1%-3% of terpene resin; 0.5%-1% of glycols, and the balance is deionized water and necessary functional additives; the functional additives include pH regulators, preservatives, anti-settling agents, etc., which are respectively used to adjust the acid-base stability of the synthesis system, improve the microbial inhibition ability during the storage period, and improve the uniformity and suspension of the glue, so as to ensure that the obtained glue has good dispersion performance, stability and bonding performance;
[0108] Start the driving component to drive the mixing blade 102 to rotate at a speed of X rpm;
[0109] Wherein, X is a variable speed of 100-300 rpm, which is used to adapt to the mixing strength requirements of glues with different ratios.
[0110] Step 2: When the mixing blade 102 rotates by Z angle, trigger the sampling component to work. The piston 300 moves upward in the defoaming tube 110 to extract a preset amount a of glue. At the same time, the defoaming tube 110 is limited by the wedge-shaped groove 400 and prohibited from rotating. After the piston 300 touches and lifts the lifting rod 405, the limit of the wedge-shaped groove 400 is released, and the defoaming tube 110 rotates at a speed of W rpm for a preset time a1, and synchronously triggers the tremor bar 409 to impact the vertical bar 411 to generate high-frequency tremors.
[0111] Step 3: The gear a309 is disengaged from the gear b313, and the piston 300 moves downward to drip the degassed glue onto the dispensing film 104 through the release tube 304. At this time, the worm gear 505 and the worm 504 of the scroll 107 are self-locked to stop the rotation of the scroll 107. The glue flows along the detection plate 103 with an inclination angle θ. It is adjusted by the positioning bolt 112, and the flow distance L is recorded through the scale mark 105. When the sampling component extracts glue next time, the transmission shaft 311 drives the scroll 107 to wind up the film, and the frame a108 and the frame b109 scrape off the residual glue.
[0112] Wherein, θ is the adjustable inclination angle of the detection plate 103, within the range of 5° to 30°. The flow distance L is used for subsequent viscosity or fluidity evaluation.
[0113] Step 4: When the flow distance L exceeds the threshold range, the supplementary addition amount of the cross-linking agent is 0.1%-0.3%, and the supplementary addition amount of the thickening agent is 0.05%-0.1%;
[0114] If the L is greater than the upper limit of the target range, it means that the viscosity of the glue is too low; for the isocyanate cross-linking agent, the supplementary addition amount is 0.1%-0.3% of the total weight; or for the thickening agent (such as hydroxyethyl cellulose), the supplementary addition amount is 0.05%-0.1%;
[0115] If the said L is less than the lower limit value of the set target range, it indicates that the viscosity of the glue is on the high side and the fluidity is insufficient. Add a cosolvent, such as ethylene glycol, to improve the intermolecular lubricity of the glue and the compatibility of the polymer. The addition amount is 0.1% - 0.3% of the total weight.
[0116] If the target fluidity requirement still cannot be met, the dosage of the hydroxyethyl cellulose thickener can be appropriately reduced, or a small amount of diluent (water or low-polarity alcohols, controlled at 0.1% - 0.2%) can be added. After the addition, perform the mixing in Step 1 and the fluidity detection in Steps 2 to 3 again until the flow distance L of the glue returns to the target range.
[0117] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

At this time, the worm wheel (505) and the worm (504) are self-locked to stop the reel (107). The glue flows along the detection plate (103) with an inclined angle θ, and is adjusted by the positioning bolt (112). The flow distance L is recorded by the scale mark (105). When the sampling component extracts glue next time, the transmission shaft (311) drives the reel (107) to reel up the film, and the frame a (108) and the frame b (109) scrape off the residual glue. Step 4: If the flow distance L recorded on the detection plate (103) exceeds the upper limit of the target range, a supplementary operation is performed to add 0.1%-0.3% of the cross-linking agent; If the flow distance L recorded on the detection plate (103) is less than the lower limit of the target range, the same replenishment operation is performed to add 0.1%-0.3% of water-based polyurethane.
