Description
Technical Field
[0001] This utility model relates to an adhesive coating device for infusion tubing. Background Technology
[0002] Disposable infusion sets are common medical consumables. After sterilization, they establish a channel between the vein and the medication for intravenous infusion. They generally consist of eight connected parts: an intravenous needle or injection needle, a needle cap, an infusion tubing, a medication filter, a flow regulator, a drip chamber, a stopper puncture device, and an air filter. Some infusion sets also have injection ports and medication dispensing ports.
[0003] The assembly of all components in a traditional disposable infusion set is completed on a disposable infusion set assembly machine. This machine has multiple workstations. After the infusion tubing is assembled with one component, a circular conveyor on the machine moves the tubing to the next assembly station. At this station, the tubing clamping device secures the tubing, facilitating its assembly with other components. When assembling the ends of the tubing with other components, the ends of the tubing are directly fitted over the ends of the other components. To ensure the stability of the infusion tubing end after assembly with other components, glue is applied to the infusion tubing end before assembly. The glue application is done through a glue applicator. However, the glue applicator inevitably shifts during the glue application process. During this shift, the glue adhering to the glue applicator falls off under the influence of gravity and the inertial force generated by the displacement, resulting in some glue being wasted and increasing glue application costs. Furthermore, if the glue spills onto other devices on the disposable infusion set, it can easily affect the normal operation of other devices once it solidifies. Summary of the Invention
[0004] The present invention aims to solve the existing technical problem by providing an adhesive coating device for infusion tubing. This device can effectively prevent adhesive from falling onto other devices on disposable infusion sets during the coating process, and can also recycle the fallen adhesive to avoid waste and effectively reduce coating costs.

First sliders matching the first slide rails are located on the left and right sides of the lower surface of the movable plate. The movable plate also has matching... A glue-applying mechanism includes several glue-applying rods evenly distributed laterally, each with a glue-applying head at its front end. A collection seat is located on the front side of the upper surface of the upper seat plate. A groove is located on the upper surface of the collection seat. Several glue troughs corresponding to the positions of the glue-applying rods are located at the bottom of the groove. The rear ends of the glue troughs are connected by a connecting groove. The upper opening of the connecting groove is located on the bottom of the groove. A fixing plate is located on the front side of the bottom of the groove. A collection plate extends upward and forward from the front end of the fixing plate. The length of the collection plate is greater than the distance between the leftmost and rightmost glue-applying rods.

[0010] The swing structure includes a hinge seat on the left wall at the rear end of the left support plate; a third cylinder is hinged to the hinge seat; a rotating shaft is provided on both the left and right sides of the swing plate; shaft holes matching the rotating shafts are provided on both the left and right support plates; a second bearing is provided between the outer wall of the rotating shaft and the inner wall of the shaft hole; the left end of the rotating shaft on the left side of the swing plate extends to the left through the left shaft hole and is provided with a swing arm; the front end of the third cylinder is inclined upwards, and the upper end of the swing arm is inclined backwards; the front end of the piston rod of the third cylinder is hinged to the upper end of the swing arm.

[0015] The beneficial effects of this utility model are:
[0016] Compared with existing technologies, the adhesive applicator of the infusion tubing adhesive applicator of this invention, when the adhesive applicator head moves forward under the action of the first cylinder, its forward stroke is always behind the upper end of the recovery plate. Therefore, even when the adhesive applicator head is applying adhesive to the end of the tubing, it is still behind the recovery plate. When the adhesive on the applicator head falls, it will only fall into the space behind the recovery plate. The upper end of the recovery plate is inclined forward, forming an inclined wall. When the adhesive falls onto the recovery plate, it will slide directly along the inclined wall towards the adhesive tank and eventually return to the adhesive tank. The adhesive is recycled. Because adhesive is sticky and has poor flowability, when a large amount of adhesive falls, it will accumulate temporarily. The groove can be used to temporarily accumulate the adhesive, preventing some of the adhesive from spreading directly to the upper left surface of the return water. This keeps the fallen adhesive concentrated in the groove area, preventing it from falling onto other devices on the disposable infusion set during the application process and affecting their normal operation. Furthermore, recycling the fallen adhesive can effectively prevent adhesive waste, thereby reducing the cost of adhesive application. Attached Figure Description

[0025] The driving structure includes a fixed seat 24 disposed on the upper surface of the swing plate 19; a second cylinder mounting bracket 25 is disposed on the right side of the fixed seat 24; a second cylinder 26 is disposed on the second cylinder mounting bracket 25 and matched therewith; the left end of the piston rod of the second cylinder 26 is disposed on the fixed seat 24; a rack 27 that meshes with the drive gear 23 is disposed at the rear end of the second cylinder mounting bracket 25; a second slide rail 28 is disposed on the upper surface of the rack 27; an extension plate 29 is disposed on the rear side of the upper end of the fixed seat 24; a second slider 30 that matches the second slide rail 28 is disposed on the lower surface of the extension plate 29.
[0026] The swing structure includes a hinge seat 31 located on the left wall of the rear end of the left support plate 18; the hinge seat 31 is hinged to a third cylinder 32; a rotating shaft 33 is provided on both the left and right sides of the swing plate 19; a shaft hole 34 matching the rotating shaft 33 is provided on both the left and right support plates 18; a second bearing 35 is provided between the outer wall of the rotating shaft 33 and the inner wall of the shaft hole 34; the left end of the rotating shaft 33 on the left side of the swing plate 19 extends to the left through the left shaft hole 34 and is provided with a swing arm 36; the front end of the third cylinder 32 is inclined upwards, and the upper end of the swing arm 36 is inclined backwards; the front end of the piston rod of the third cylinder 32 is hinged to the upper end of the swing arm 36.
[0027] The fixing plate 15 is fixed to the bottom of the groove 12 by a number of horizontally evenly distributed screws.
[0028] The glue applicator 10 is located at the center of the front end face of the glue applicator 9.
[0029] The outer wall of the glue applicator 10 is provided with several circumferentially evenly distributed receiving grooves 39.
[0030] The adhesive applicator 10 is tubular.
[0031] The method of using this utility model is as follows:
[0032] When the infusion tubing 37 is conveyed to the position of the infusion tubing adhesive applicator by the annular conveying device on the disposable infusion set assembly equipment, several infusion tubing 37 will be directly clamped by the infusion tubing clamping device 38 to facilitate the adhesive applicator work. At this time, the end of the infusion tubing 37 to be coated with adhesive is coaxial with the adhesive applicator rod 9.
[0033] When it is necessary to apply adhesive to the end of the infusion tubing 37, the third cylinder 32 can be activated. At this time, the piston rod of the third cylinder 32 pushes forward and upward, causing the swing arm 36 to swing forward around the rotating shaft 33. When the swing arm 36 swings forward, the rotating shaft 33 rotates synchronously. The rotating shaft 33 is located on the left and right sides of the swing plate 19. When the rotating shaft 33 rotates, the swing plate 19 rotates accordingly, thereby realizing the rotation of the adhesive application rod 9. At this moment, the adhesive application rod 9, along with the adhesive application head 10, tilts downward, so that the adhesive application rod 9, along with the adhesive application head 10, enters the glue tank 13 and is immersed in the glue in the glue tank 13, so that the adhesive application head 10 at the front end of the adhesive application rod 9 is contaminated with glue. At this time, the third cylinder 32 can be activated again to reset the piston rod of the third cylinder 32, so that the adhesive application head 10 at the front end of the adhesive application rod 9 tilts upward and resets.
[0034] After the glue applicator 9 is reset, the first cylinder 6 can be activated. The piston rod of the first cylinder 6 will push the moving plate 7 forward, causing the moving plate 7 to move stably forward along the trajectory of the first slide rail 4. The upper surface of the moving plate 7 is provided with support plates 18 on the left and right sides, and the swing plate 19 is located between the left and right support plates 18. Therefore, the swing plate 19 will move forward synchronously, thereby realizing the forward movement of the glue applicator head 10 at the front end of the glue applicator 9. During the forward movement of the glue applicator head 10, the second cylinder 26 is activated synchronously. At this time, the piston rod of the second cylinder 26 pushes out or retracts. With the fixed seat 24 fixed, the cylinder body of the second cylinder 26 will move. The cylinder body of the second cylinder 26 and the gear The racks 27 are connected by the second cylinder mounting bracket 25. When the cylinder body of the second cylinder 26 moves, the rack 27 moves synchronously and meshes with the drive gear 23, causing the drive gear 23 to rotate. The drive gear 23 is mounted on one of the glue-applying rods 9. When the drive gear 23 rotates, the drive gear 22 on the glue-applying rod 9 with the drive gear 23 rotates. The adjacent drive gears 22 mesh with each other. When one drive gear 22 rotates, the other drive gears 22 will rotate synchronously. When the drive gear 22 rotates, the glue-applying rod 9 rotates accordingly, thereby realizing the rotation of all glue-applying rods 9.
[0035] At this time, the glue applicator 9, along with the glue applicator head 10, rotates and moves forward, eventually contacting the end of the infusion tubing 37. If glue needs to be applied to the inner wall of the end of the infusion tubing 37, the glue applicator head 10 can be needle-shaped, making it easy to insert into the end of the infusion tubing 37. If glue needs to be applied to the outer wall of the end of the infusion tubing 37, the glue applicator head 10 can be tubular, directly fitting the end of the infusion tubing 37 inside and contacting the outer wall of the end of the infusion tubing 37. The glue applicator head 10 will rotate continuously during glue application, effectively ensuring the uniformity of glue application and facilitating the bonding and fixation between the end of the infusion tubing 37 and other components after glue application. After the glue application is completed, the first cylinder 6 will move the glue applicator head 10 backward to reset, the second cylinder 26 will stop operating, and the glue applicator 9 and the glue applicator head 10 will no longer rotate, ready for the next glue application.
[0036] When the glue applicator head 10 of the glue applicator rod 9 moves forward under the action of the first cylinder, its forward stroke is always behind the upper end of the recovery plate 16. Therefore, even when the glue applicator head 10 is applying glue to the end of the infusion tubing 37, the glue applicator head 10 is still behind the recovery plate. When the glue on the glue applicator head 10 falls, the glue will only fall into the space behind the recovery plate 16. The upper end of the recovery plate 16 is inclined forward, forming an inclined wall. When the glue falls onto the recovery plate 16, it will slide directly along the inclined wall towards the glue tank 13 and eventually return to the glue tank 13, completing the glue application. Water recycling is important because the glue itself is viscous and has poor fluidity. When a large amount of glue falls, it will accumulate temporarily. The groove 12 can be used to temporarily accumulate the glue, preventing some of the glue from spreading directly to the surface of the recycling seat 11. This keeps the fallen glue concentrated in the area of the groove, preventing it from falling onto other devices on the disposable infusion set during the glue application process and affecting their normal operation. Furthermore, recycling the fallen glue can effectively prevent glue waste, thereby reducing glue application costs.
[0037] The rear ends of several glue tanks 13 are connected by a connecting groove 14. After the glue in each glue tank 13 comes into contact with the glue applicator 10, the amount of glue that gets on it will be different. The existence of the connecting groove 14 can ensure that the glue in all glue tanks 13 is always at the same level, so as to avoid the situation where the glue level in different glue tanks 13 is different, which will cause the glue application quality of the infusion tubing to be different, thus ensuring the glue application quality to the greatest extent.
[0038] The left and right side walls of the recycling seat 11 are provided with a glue replacement hole 17 that communicates with the bottom of the connecting groove 14. If a problem is found with the glue in the glue tank 13, the glue in the glue tank 13 can be quickly discharged through the glue replacement hole 17, and then new glue can be injected through the upper opening of the glue tank 13. When not in use, the glue replacement hole 17 can be blocked and sealed with a plug.
[0039] The fixing plate 15 is fixed to the bottom of the groove 12 by a number of horizontally evenly distributed screws. This fixing method facilitates the disassembly and assembly of the fixing plate 15 and the bottom of the groove 12, thereby facilitating the disassembly and assembly of the recycling plate 16 and making it easier to replace the recycling plate 16 with different inclinations.
[0040] The outer wall of the glue applicator 10 is provided with several circumferentially evenly distributed receiving grooves 39. When the glue applicator 10 comes into contact with the glue in the glue tank 13, a portion of the glue will be directly stored in the receiving groove 10, thereby effectively ensuring the amount of glue when the glue applicator 10 applies the glue and ensuring the quality of the glue application. In order to ensure the storage effect of the receiving groove, the glue applicator 10 can be rotated after it enters the end of the infusion tubing 37.
