Description

Technical Field

[0001] This invention relates to the field of swab flocking equipment technology, specifically an adjustable swab flocking and adhesive-spreading device. Background Technology

[0002] The production of swabs generally involves the following steps: after the swabs are removed from the mold, workers install them one by one into a special mold and clamp them. Then, they are manually dipped in glue. After dipping, they are placed in a glue-spinning machine for glue spinning. After glue spinning, they are sent to a flocking machine for flocking. After flocking, they are dried, and the swabs are made. However, each process has always required manual operation, making it impossible to achieve automated production. Operators have been engaged in simple, repetitive labor for a long time. The glue that is spun onto the inner wall of the glue-spinning cylinder is easy to stick to the inner wall and is difficult to clean. This not only wastes resources but also easily attracts dust, causing contamination of the swabs. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable swab flocking and adhesive-spreading device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an adjustable swab flocking and glue-spraying device, comprising a plurality of swab strips for demolding, glue, and a support. The support is provided with a sorting component, a guide rail, and a glue-applying component. The plurality of swab strips are arranged on the sorting component, and a transfer component is arranged below the sorting component to move the plurality of swab strips. A glue-spraying component is installed on the guide rail to clamp the swab strips. The glue is stored in the glue-applying component. The glue-spraying component also dips and sprays the swab strips with glue, and the glue-applying component collects the glue.

[0005] Furthermore, the sorting assembly includes a sorter, a pusher plate, and a rack. The sorter is mounted on a support and has a two-layer structure. The upper layer of the sorter has a long groove, and the bottom of the long groove has several fine grooves evenly distributed thereon, the length of which is the same as the length of the long groove. The pusher plate is slidably mounted on the two side walls of the long groove, and one side of the long groove is open to the outside of the upper layer of the sorter. The rack is located on the outer side of the upper layer of the sorter, on the side of the long groove that is open to the outside. A servo motor is installed inside the pusher plate, and a dial is connected to the servo motor. The device is equipped with a grooved wheel on the outside, which cooperates with the dial wheel. A gear is coaxially mounted on the grooved wheel, and the gear cooperates with the rack. Before using the device to impregnate and spin the swab strips with glue, the operator first places several swab strips in the long groove of the sorter. Each swab on each swab strip falls into the narrow groove. The servo motor is powered on to drive the dial wheel to rotate, which drives the grooved wheel to rotate intermittently. The grooved wheel drives the gear to rotate intermittently. The gear, through meshing with the rack, drives the push plate to move intermittently. Each time the push plate moves, it pushes a swab strip off the sorter, and the swab strips behind it move forward to fill the gap.

[0006] Furthermore, several probes are rotatably arranged below the long groove of the sorter. These probes contact the swab strips and are all connected to the control system. All probes are connected to the same detection circuit, which is also connected to the control system. Before each swab strip is pushed off the sorter, each swab on the strip contacts one probe. When all probes are aligned, the detection circuit remains on. A weight is provided at the end of each probe away from the swab strip. If a swab is defective or broken, the end of the probe with the weight swings down, while the end in contact with the swab strip pushes up, causing all probes to lose alignment and disconnecting the detection circuit. The control system monitors the power supply to and from the detection circuit to identify defects or breaks in the swabs.

[0007] Furthermore, the lower layer of the sorter is a hollow square tube, with a rotatable cover mounted on one end. A coil spring is provided at the rotatable connection between the cover and the hollow square tube. A first electromagnet is installed inside the hollow square tube, and arc-shaped grooves are provided on both sides of the hollow square tube. A stop block is provided on the cover at the position corresponding to the arc-shaped groove, and the stop block is slidably positioned in the arc-shaped groove. The first electromagnet attracts the cover. When the control system detects that the detection circuit is de-energized, it indicates that the swab label array about to be pushed off the sorter has a defect. The control system de-energizes the first electromagnet, releasing it from its hold on the bin cover. The bin cover opens outward under the action of the coil spring, and the push plate pushes out the swab strips. The swab strips are blocked by the bin cover and fall into the hollow square tube. They then slide down the slope of the hollow square tube into the material drop box, making it convenient for operators to handle defective swab strips. If there is no problem with the swab strips, the control system keeps the first electromagnet energized, and the first electromagnet holds the bin cover. The swab strips pushed off by the push plate fall down into the swab groove on the track.

[0008] Furthermore, the sorter is tilted, and an ultrasonic rangefinder is installed above it, located near the bin cover. A material drop box is located at the end of the sorter furthest from the bin cover. The height of the sorter gradually decreases from the bin cover side to the material drop box side. The ultrasonic rangefinder identifies the height of the swab strips placed in the long groove. Subsequently, the control system drives two first electric push rods to move. The two first electric push rods adjust the side plate frame to different heights. When the height of the swab strips is higher, the two first electric push rods drive the side plate frame to lower; when the height of the swab strips is lower, the two first electric push rods drive the side plate frame to rise. That is, the height of the top of the swab strips after they are inserted into the swab groove remains unchanged, allowing the gripper to grip different types of swabs at the same height, improving the stability of the gripper's operation.

[0009] Furthermore, the transmission assembly includes two first electric push rods and a side plate frame. The side plate frame is mounted on the two first electric push rods. A transmission wheel, a driven wheel, and a transmission motor are disposed on the side plate frame. The transmission motor is coaxially mounted with the transmission wheel. A track is installed between the transmission wheel and the driven wheel. Grooves are formed on both sides of the track, and several wiping grooves are formed on the surface of the track. A pair of upper auxiliary wheels and a pair of lower auxiliary wheels are also disposed on the side plate frame. The pair of upper auxiliary wheels and the pair of lower auxiliary wheels are arranged opposite each other and are all disposed in the grooves. The position of the upper auxiliary wheels is higher than that of the lower auxiliary wheels. The transmission motor drives the transmission wheel to rotate, and the transmission wheel drives the track and the driven wheel to move. The upper auxiliary wheels are positioned below the location where the swab strips are pushed off the sorter. When the track moves past the position of the pair of upper auxiliary wheels, the track bulges upward and deforms, meaning the opening of the swab groove at the deformed position is widened. The widened opening of the swab groove makes it easier for the swab strips to be inserted. As the drive wheel drives the track to continue moving, under the action of the pair of lower auxiliary wheels, the track returns from the deformed bulging state to a straight state, and the opening of the swab groove also returns to its original shape, providing a certain degree of clamping and stabilizing effect for the swab strips that have fallen into the swab groove. Each time the push plate pushes the swab strips to move, the control system controls the drive motor to rotate by an angle, so that the swab strips are arranged sequentially on the track, making it easier for the gripper to pick up multiple swab strips.

[0010] Furthermore, the spun glue assembly includes a movable seat and an internal gear ring wheel. The movable seat has an open center and is slidably mounted on a guide rail. Inside the movable seat are a main motor, a track wheel, an internal gear, and a gear motor. The track wheel is mounted on the main motor, and the internal gear is mounted on the gear motor. The track wheel is in contact with the guide rail. The internal gear ring wheel is rotatably mounted on the movable seat. The inner ring of the internal gear ring wheel has a toothed groove that meshes with the internal gear for transmission. The movable seat and the internal gear ring wheel have a notch of the same size on one side. When the main motor is energized, it drives the track wheel to rotate. The track wheel drives the movable seat to move on the guide rail through the friction between itself and the guide rail. The notch on the movable seat and the internal gear ring wheel allows the movable seat to pass through the connection between the guide rail and the support when it moves on the guide rail, thus avoiding interference.

[0011] Furthermore, a second electric push rod is installed on the internal gear ring wheel. A chuck is installed at one end of the second electric push rod. The chuck has several slots. Inside the chuck are a locking hook, a second electromagnet, and a return spring. The locking hook is slidably installed inside the chuck. The return spring is located between the locking hook and the second electromagnet. When the moving seat moves above the track, the second electric push rod drives the chuck to descend. Several swab strips are inserted into several slots of the chuck. The control system energizes the second electromagnet, which attracts the locking hook to move. The locking hook extends into the slot and hooks the swab strips. The second electric push rod drives the chuck to rise, and the swab strips leave the track and move with the chuck.

[0012] Furthermore, the glue application assembly includes a glue-spinning cylinder and a glue-spinning cylinder motor. The glue-spinning cylinder is rotatably mounted on a bracket. A synchronous gear is connected to the glue-spinning cylinder motor. A roller is coaxially mounted on the side of the synchronous gear away from the glue-spinning cylinder motor. An internal tooth groove is opened on the inner ring of the glue-spinning cylinder near the end of the glue-spinning cylinder motor. The synchronous gear meshes with the internal tooth groove. The roller contacts the inner wall of the glue-spinning cylinder.

[0013] Furthermore, the gluing assembly also includes a glue container, a connecting pipe, a jacket, and an air pump. The glue container contains glue. The roller has a hollow structure with several small holes on its surface, which communicate with the center of the roller. One end of the connecting pipe is rotatably connected to the roller, and the connecting pipe communicates with the center of the roller. The end of the connecting pipe away from the roller is located in the glue container. A jacket is also provided at the end of the connecting pipe away from the roller, forming an empty space between the jacket and the connecting pipe. The empty space is connected to the air pump through a pipe. Several oblique holes are provided at the end of the connecting pipe away from the roller, and these oblique holes communicate with the empty space. The moving base is driven by the main motor. Moved below the glue container, the control system controls the second electric actuator to lower the clamp again, causing the swabs hooked on the clamp to be dipped into the glue in the glue container. The control system then controls the second electric actuator to raise the clamp, draining off the excess glue from the swabs. The main motor is powered on, causing the moving seat to move along the guide rail into the glue-spraying cylinder. The control system then powers on the gear motor, which drives the internal gear to rotate. Since the position of the internal gear is fixed, the internal gear ring wheel begins to rotate around the moving seat. The internal gear ring wheel, in turn, causes the clamp to rotate along with the second electric actuator. Under the action of centrifugal force, the glue dipped on the swabs on the clamp is thrown onto the inner wall of the glue-spraying cylinder.

[0014] The control system then controls the rotation of the glue cylinder motor, which drives the synchronous gear and rollers to rotate simultaneously. The synchronous gear drives the glue-spinning cylinder to rotate through its internal tooth grooves. At the same time, the rollers contact the inner wall of the glue-spinning cylinder and roll purely against it. There is no gap at the contact point between the rollers and the glue-spinning cylinder. As the glue-spinning cylinder rotates, the glue adhering to the inner wall of the cylinder is blocked by the rollers, causing the glue to gradually accumulate. Since the rollers are also rolling, the glue splashed onto the rollers cannot adhere to the surface, thus cleaning the inner wall of the glue-spinning cylinder. While the glue cylinder motor is working, the air pump also starts operating. The air pump draws in air and squeezes it through the pipe between the connecting pipe and the jacket. Finally, the air is discharged from several oblique holes on the connecting pipe, causing the air pressure at the pipe opening to drop. The glue trapped by the rollers is then drawn into the connecting pipe through the inside of the rollers. This splashed glue eventually flows back into the glue container, achieving glue recycling, reducing resource waste, preventing environmental pollution, and lowering production costs.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] 1. By setting up several probes to detect the quality of the swab strips, each swab on the strip is in contact with a probe. The detection circuit remains connected only when all the probes are aligned. If a swab is defective or broken, the probe is pushed upward by its own weight, causing all the probes to break alignment and the detection circuit to disconnect. The control system monitors the power supply to the detection circuit to identify defects or breaks in the swabs. The automatic sorting is fast and accurate, reduces manual labor, and avoids material waste in the flocking process.

[0017] 2. By setting a movable seat on the track, the main motor inside the movable seat drives the track wheel to rotate. The track wheel drives the movable seat to move on the guide rail through the friction between the track wheel and the guide rail. An internal gear ring wheel and a chuck are set on the movable seat. The chuck grips the swab strips. The movable seat drives the chuck to move, and the internal gear ring wheel drives the chuck to rotate, automatically completing the glue impregnation and glue spinning work, realizing seamless handover between the two processes, improving work efficiency and reducing manual intervention.

[0018] 3. The glue cylinder motor drives the glue-spinning cylinder and roller to rotate. The roller is in contact with the inner wall of the glue-spinning cylinder and rolls continuously. The glue that is spun from the swab strip onto the inner wall of the glue-spinning cylinder is intercepted by the roller and is kept to one side. Since the roller is also rolling, the glue that is spun onto the roller cannot adhere to the surface, thus cleaning the inner wall of the glue-spinning cylinder. The air pump draws in air and squeezes it through the pipe between the connecting pipe and the jacket. Finally, the air is discharged from several oblique holes on the connecting pipe, causing the air pressure at the pipe opening to drop. The glue that is intercepted by the roller is then drawn into the glue container through the inside of the roller, realizing the recycling of the glue, reducing resource waste, preventing environmental pollution, and reducing production costs.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-12 The present invention provides a technical solution: an adjustable swab flocking and glue-spraying device, including a plurality of swab strips 37 for demolding, glue, and a support 1. The support 1 is provided with a sorting component, a guide rail 18, and a glue-applying component. The plurality of swab strips 37 are arranged on the sorting component, and a transfer component is arranged below the sorting component. The transfer component moves the plurality of swab strips 37. A glue-spraying component is installed on the guide rail 18. The glue-spraying component clamps the swab strips 37. The glue is stored in the glue-applying component. The glue-spraying component also dips and sprays the swab strips 37 with glue. The glue-applying component collects the glue.

[0035] The sorting assembly includes a sorter 2, a pusher plate 6, and a rack 3. The sorter 2 is mounted on a bracket 1 and has a two-layer structure. The upper layer of the sorter 2 has a long groove, and several fine grooves are evenly distributed at the bottom of the long groove. The length of the fine grooves is the same as the length of the long groove. The pusher plate 6 is slidably mounted on the two side walls of the long groove. One side of the long groove is open to the outside of the upper layer of the sorter 2. The rack 3 is located on the outside of the upper layer of the sorter 2, on the side of the long groove that is open to the outside. A servo motor (not shown in the figure) is installed inside the pusher plate 6, and a dial wheel 9 is connected to the servo motor. A grooved wheel 8 is installed on the outside of the pusher plate 6. The grooved wheel 8 and the dial wheel 9 cooperate with each other. A gear 7 is coaxially mounted on wheel 8. Gear 7 meshes with rack 3. Before using this device to impregnate and spin the swab strips, the operator places several swab strips 37 into the long slot of sorter 2. Each swab on each swab strip 37 falls into the narrow slot. The servo motor is powered on to drive the dial wheel 9 to rotate. The dial wheel 9 drives the slotted wheel 8 to rotate intermittently. The slotted wheel 8 drives the gear 7 to rotate intermittently. The gear 7, through meshing with rack 3, drives push plate 6 to move intermittently. Each time push plate 6 moves, it pushes a swab strip 37 off sorter 2, and the swab strip 37 behind it moves forward to fill the gap.

[0036] The sorter 2 is tilted, and a material drop box 10 is located at the end of the sorter 2 away from the bin cover 4. The height of the sorter 2 gradually decreases from the bin cover 4 side to the material drop box 10 side. Several probes 36 are rotatably arranged below the long groove of the sorter 2. The probes 36 are in contact with the swab label row 37 and are all connected to the control system. The lower layer of the sorter 2 is a hollow square tube, and the bin cover 4 is rotatably installed at one end of the hollow square tube. A coil spring (not shown in the figure) is provided at the rotatable connection between the bin cover 4 and the hollow square tube. A first electromagnet 5 is installed inside the hollow square tube. Arc-shaped grooves are provided on both sides of the hollow square tube. A stop block is installed on the cover 4 at the position corresponding to the arc-shaped groove, and the stop block slides within the arc-shaped groove. The first electromagnet 5 attracts the cover 4. All the probes 36 are connected to the same detection circuit, which is connected to the control system. Before each swab strip 37 is pushed down the sorter 2, each swab on the swab strip 37 contacts one probe 36, ensuring that all probes 36 remain aligned. When all swabs are aligned, the detection circuit remains connected. Several detection needles 36 have weights at the ends furthest from the swab strip array 37. If a swab is defective or broken, the end of the detection needle 36 with the weight swings down, while the end in contact with the swab strip array 37 pushes upwards, causing all the detection needles 36 to become misaligned. This disconnects the detection circuit. When the control system detects the de-energization of the detection circuit, it indicates that the swab strip array 37 about to be pushed off the sorter 2 has a defect. The control system then de-energizes the first electromagnet 5, causing it to disengage. In addition to adsorbing the bin cover 4, the bin cover 4 opens outward under the action of the coil spring, and the push plate 6 pushes out the swab strip 37. The swab strip 37 is blocked by the bin cover 4 and falls into the hollow square tube. Then it slides down the slope of the hollow square tube into the material box 10, which makes it convenient for the operator to deal with the defective swab strip 37. If the swab strip 37 is not problematic, the control system keeps the first electromagnet 5 energized. The first electromagnet 5 adsorbs the bin cover 4, and the swab strip 37 pushed down by the push plate 6 falls down into the swab groove on the track 17.

[0037] The transmission assembly includes two first electric actuators 11 and a side plate frame 12. The side plate frame 12 is mounted on the two first electric actuators 11. A transmission wheel 13, a driven wheel 14, and a transmission motor (not shown in the figure) are arranged on the side plate frame 12. The transmission motor is coaxially mounted with the transmission wheel 13. A track 17 is installed between the transmission wheel 13 and the driven wheel 14. Grooves are formed on both sides of the track 17, and several wiping grooves are formed on the surface of the track 17. A pair of upper auxiliary wheels 15 and a pair of lower auxiliary wheels 16 are also provided on the side plate frame 12. The pair of upper auxiliary wheels 15 and the pair of lower auxiliary wheels 16 are arranged opposite to each other. The upper auxiliary wheel 15 and a pair of lower auxiliary wheels 16 are both set in the groove. The position of the upper auxiliary wheel 15 is higher than that of the lower auxiliary wheel 16. The drive motor drives the drive wheel 13 to rotate, and the drive wheel 13 drives the track 17 and the driven wheel 14 to move. The position of the pair of upper auxiliary wheels 15 is below the position where the swab strip 37 is pushed off the sorter 2. When the track 17 moves past the position of the pair of upper auxiliary wheels 15, the track 17 bulges upward and deforms. That is, the groove of the swab slot at the deformation position of the track 17 is expanded. The expanded swab groove makes it easier to insert the swab strip 37. As the drive wheel 13 drives the track 17 to move, the track 17 moves. As the belt 17 continues to move, under the action of a pair of lower auxiliary wheels 16, the belt 17 returns from its deformed and bulging state to a straight state, and the opening of the swab groove also returns to its original shape, providing a certain clamping and stabilizing effect on the swab strips 37 that have fallen into the swab groove. Each time the push plate 6 pushes the swab strips 37 to move, the control system controls the transmission motor to rotate by an angle, so that the swab strips 37 are arranged sequentially on the belt 17, making it easier for the chuck 22 to clamp multiple swab strips 37. An ultrasonic rangefinder 38 is installed above the sorter 2, and the ultrasonic rangefinder 38 is located on the side near the bin cover 4, using ultrasonic measurement... The distance measuring instrument 38 identifies the height of the swab strip 37 placed in the long slot, and then drives the two first electric push rods 11 to move through the control system. The two first electric push rods 11 adjust the side plate frame 12 to different heights. When the height of the swab strip 37 is higher, the two first electric push rods 11 drive the side plate frame 12 to lower. When the height of the swab strip 37 is lower, the two first electric push rods 11 drive the side plate frame 12 to rise. That is, the height of the top of the swab strip 37 after it is inserted into the swab slot remains unchanged, so that the clamp 22 can clamp different types of swabs at the same height.

[0038] The spun glue assembly includes a movable base 19 and an internal gear ring wheel 20. The movable base 19 has an open center and is slidably mounted on a guide rail 18. Inside the movable base 19 are a main motor 26, a track wheel 27, an internal gear 25, and a gear motor (not shown in the figure). The track wheel 27 is mounted on the main motor 26, and the internal gear 25 is mounted on the gear motor. The track wheel 27 is in contact with the guide rail 18. The internal gear ring wheel 20 is rotatably mounted on the movable base 19. The inner ring of the internal gear ring wheel 20 has a toothed groove that meshes with the internal gear 25. The movable base 19 and the internal gear ring wheel 20 have a notch of the same size on one side. A second electric push rod 21 is mounted on the internal gear ring wheel 20. A chuck 22 is mounted on one end of the second electric push rod 21. The chuck 22 has several slots and contains a locking hook 24, a second electromagnet 23, and a return spring (not shown in the figure). The sliding mount is installed inside the chuck 22. The return spring is located between the locking hook 24 and the second electromagnet 23. The main motor 26 is energized to drive the track wheel 27 to rotate. The track wheel 27 drives the moving seat 19 to move on the guide rail 18 through the friction between the track wheel 27 and the guide rail 18. The moving seat 19 and the internal gear ring wheel 20 have notches so that the moving seat 19 can pass through the connection between the guide rail 18 and the bracket 1 when it moves on the guide rail 18, so as to avoid interference. When the moving seat 19 moves above the track 17, the second electric push rod 21 drives the chuck 22 to descend. Several swab strips 37 are inserted into several slots of the chuck 22. The control system energizes the second electromagnet 23. The second electromagnet 23 attracts the locking hook 24 to move. The locking hook 24 extends into the slot and hooks the swab strips 37. The second electric push rod 21 drives the chuck 22 to rise. The swab strips 37 leave the track 17 and move with the chuck 22.

[0039] The glue application assembly includes a glue-spinning cylinder 29, a glue cylinder motor 30, a glue container 28, a connecting pipe 33, a jacket 34, and an air pump 35. The glue-spinning cylinder 29 is rotatably mounted on a bracket 1. A synchronous gear 31 is connected to the glue cylinder motor 30. A roller 32 is coaxially mounted on the side of the synchronous gear 31 away from the glue cylinder motor 30. An internal tooth groove is formed on the inner ring of the glue-spinning cylinder 29 near the glue cylinder motor 30. The synchronous gear 31 meshes with the internal tooth groove. The roller 32 contacts the inner wall of the glue-spinning cylinder 29. The container 28 contains glue. The roller 32 is hollow and has several small holes on its surface, which are connected to the middle of the roller 32. One end of the connecting pipe 33 is rotatably connected to the roller 32 and is connected to the middle of the roller 32. The end of the connecting pipe 33 away from the roller 32 is located in the glue container 28. A sleeve 34 is also provided at the end of the connecting pipe 33 away from the roller 32, forming an empty space between the sleeve 34 and the connecting pipe 33. The empty space is connected to the air pump 35 through a pipe. Connected to the roller 32, the end of the connecting pipe 33 away from the roller 32 has several oblique holes, which communicate with the empty interlayer. The moving seat 19 moves to the bottom of the glue container 28 under the drive of the main motor 26. The control system controls the second electric push rod 21 to drive the chuck 22 to descend again, so that the swab strip 37 hooked on the chuck 22 is dipped into the glue in the glue container 28. The control system controls the second electric push rod 21 to drive the chuck 22 to rise, so that the excess glue dipped on the swab strip 37 is drained off. When the main motor 26 is powered on, it drives the movable seat 19 to move along the guide rail 18 into the glue-spinning cylinder 29. The control system powers on the gear motor, which drives the internal gear 25 to rotate. Since the position of the internal gear 25 is fixed, the internal gear ring wheel 20 begins to rotate around the movable seat 19. The internal gear ring wheel 20 then causes the clamp 22 to rotate together through the second electric push rod 21. Under the action of centrifugal force, the glue soaked on the swab strip 37 on the clamp 22 is thrown onto the inner wall of the glue-spinning cylinder 29.

[0040] The control system then controls the rotation of the glue cylinder motor 30, which drives the synchronous gear 31 and roller 32 to rotate simultaneously. The synchronous gear 31 drives the glue-spinning cylinder 29 to rotate through its internal tooth groove. At the same time, the roller 32 contacts the inner wall of the glue-spinning cylinder 29 and rolls purely against it. There is no gap at the contact point between the roller 32 and the glue-spinning cylinder 29. As the glue-spinning cylinder 29 rotates, the glue adhering to the inner wall of the glue-spinning cylinder 29 is blocked by the roller 32, causing the glue to gradually accumulate. Since the roller 32 is also rolling, the glue that is splashed onto the roller 32 cannot adhere to the surface. The inner wall of the glue-spinning cylinder 29 is cleaned. While the glue cylinder motor 30 is working, the air pump 35 also starts to operate. The air pump 35 draws in gas and squeezes it through the pipe between the connecting pipe 33 and the jacket 34. Finally, the gas is discharged from several oblique holes on the connecting pipe 33, which causes the air pressure at the opening of the connecting pipe 33 to decrease. The glue trapped by the roller 32 is drawn into the connecting pipe 33 through the inside of the roller 32. The glue that is spinned out eventually flows back into the glue container 28. The swabs 37 after being spinned enter the flocking machine. After flocking is completed, they are dried and finally the finished product is sent out.

[0041] The working principle of this invention is as follows: Before using this device to impregnate and spin-dry the swab strips, the operator first places several swab strips 37 into the long groove of the sorter 2. Each swab on each swab strip 37 falls into the narrow groove. The servo motor is powered on, driving the dial wheel 9 to rotate. The dial wheel 9 drives the grooved wheel 8 to rotate intermittently. The grooved wheel 8 drives the gear 7 to rotate intermittently. The gear 7, through meshing with the rack 3, drives the push plate 6 to move intermittently. Each time the push plate 6 moves, it pushes one swab strip 37 off the sorter 2, and the swab strips 37 behind it move forward to fill the gap. All the probes 36 are connected to the same detection circuit. Before each swab strip 37 is pushed off the sorter 2, each swab on the swab strip 37 is in contact with one probe 36. The detection circuit remains connected only when all the probes 36 are aligned. The ends of several probes 36 away from the swab strip 37 are positioned... If a swab is defective or broken, the end of the probe 36 with the weight will swing downwards, while the end in contact with the swab row 37 will push upwards. This causes all the probes 36 to become misaligned, disconnecting the detection circuit. When the control system detects the power failure of the detection circuit, it indicates that the swab row 37 about to be pushed off the sorter 2 has a defect. The control system then de-energizes the first electromagnet 5, releasing it from its attraction to the compartment cover 4. The compartment cover 4 then retracts into the coil spring. Under the action of the push plate 6, the push plate 6 opens outward and pushes out the swab strip 37. The swab strip 37 is blocked by the cover 4 and falls into the hollow square tube. Then it slides down the slope of the hollow square tube into the material box 10, which makes it convenient for the operator to deal with the defective swab strip 37. If the swab strip 37 is not problematic, the control system keeps the first electromagnet 5 energized. The first electromagnet 5 attracts the cover 4, and the swab strip 37 pushed down by the push plate 6 falls down into the swab groove on the track 17.

[0042] The height of the swab strip 37 placed in the long slot is identified using an ultrasonic rangefinder 38. Then, the control system drives the first electric push rod 11 to move. The first electric push rod 11 adjusts the side plate frame 12 to different heights. When the swab strip 37 is at a higher height, the first electric push rod 11 lowers the position of the side plate frame 12; when the swab strip 37 is at a lower height, the first electric push rod 11 raises the position of the side plate frame 12. That is, the height of the top of the swab strip 37 after it is inserted into the swab slot remains unchanged. The drive motor drives the drive wheel 13 to rotate, and the drive wheel 13 drives the track 17 and the driven wheel 14 to move. The position of a pair of upper auxiliary wheels 15 is below the position where the swab strip 37 is pushed off the sorter 2. When the track... When track 17 moves past the position of a pair of upper auxiliary wheels 15, track 17 bulges upward and deforms, that is, the opening of the swab groove at the deformed position of track 17 is expanded. The expanded swab groove opening is more conducive to the insertion of swab strips 37. As the transmission wheel 13 drives track 17 to continue moving, under the action of a pair of lower auxiliary wheels 16, track 17 returns from the deformed bulging state to a straight state, and the opening of the swab groove also returns to its original state, which plays a certain role in clamping and stabilizing the swab strips 37 that have fallen into the swab groove. Every time push plate 6 pushes swab strips 37 to move once, the control system controls the transmission motor to rotate by an angle, so that swab strips 37 are arranged sequentially on track 17, making it easier for chuck 22 to clamp multiple swab strips 37.

[0043] The main motor 26 is energized, driving the track wheel 27 to rotate. The track wheel 27, through friction with the guide rail 18, drives the movable seat 19 to move along the guide rail 18. Notches are provided on the movable seat 19 and the internal gear ring wheel 20, allowing the movable seat 19 to pass through the connection between the guide rail 18 and the bracket 1 during its movement, preventing interference. When the movable seat 19 moves above the track 17, the second electric push rod 21 drives the chuck 22 to descend, and several swab strips 37 are inserted into several slots in the chuck 22. The control system energizes the second electromagnet 23, causing the second electromagnet 23 to attract and move the locking hook 24. The locking hook 24 extends into the slot and hooks the swab strips 37. The second electric push rod 21 drives the chuck 22 to rise, and the swab strips 37 leave the track 17 and move with the chuck 22. The movable seat 19 moves along the track 18. Driven by the movement, the device moves to the bottom of the glue container 28. The control system controls the second electric push rod 21 to drive the clamp 22 to descend again, so that the swab strip 37 hooked on the clamp 22 is dipped into the glue in the glue container 28. The control system controls the second electric push rod 21 to drive the clamp 22 to rise, so that the excess glue on the swab strip 37 is drained off. The main motor 26 is powered on, which drives the moving seat 19 to move along the guide rail 18 into the glue-spraying cylinder 29. The control system powers on the gear motor, which drives the internal gear 25 to rotate. Since the position of the internal gear 25 is fixed, the internal gear ring wheel 20 begins to rotate around the moving seat 19. The internal gear ring wheel 20 then causes the clamp 22 to rotate together through the second electric push rod 21. Under the action of centrifugal force, the glue dipped on the swab strip 37 on the clamp 22 is thrown onto the inner wall of the glue-spraying cylinder 29.

[0044] The control system then controls the rotation of the glue cylinder motor 30, which drives the synchronous gear 31 and roller 32 to rotate simultaneously. The synchronous gear 31 drives the glue-spinning cylinder 29 to rotate through its internal tooth groove. At the same time, the roller 32 contacts the inner wall of the glue-spinning cylinder 29 and rolls purely against it. There is no gap at the contact point between the roller 32 and the glue-spinning cylinder 29. As the glue-spinning cylinder 29 rotates, the glue adhering to the inner wall of the glue-spinning cylinder 29 is blocked by the roller 32, causing the glue to gradually accumulate. Since the roller 32 is also rolling, the glue that is splashed onto the roller 32 cannot adhere to the surface. The inner wall of the glue-spinning cylinder 29 is cleaned. While the glue cylinder motor 30 is working, the air pump 35 also starts to operate. The air pump 35 draws in gas and squeezes it through the pipe between the connecting pipe 33 and the jacket 34. Finally, the gas is discharged from several oblique holes on the connecting pipe 33, which causes the air pressure at the opening of the connecting pipe 33 to decrease. The glue trapped by the roller 32 is drawn into the connecting pipe 33 through the inside of the roller 32. The glue that is spinned out eventually flows back into the glue container 28. The swabs 37 after being spinned enter the flocking machine. After flocking is completed, they are dried and finally the finished product is sent out.
