[0034] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0035] Please see Figures 1 to 4 As shown, this embodiment provides an automatic adhesive applicator for flexible tubes, including a flexible tube conveying line 1, an adhesive dipping and applicating assembly 2, and a clamping assembly 3, wherein:

[0036] The hose conveyor line 1 is provided with several loading positions 11. Each loading position 11 is arranged at equal intervals along the conveying direction of the hose conveyor line 1. Each loading position 11 is loaded with a hose workpiece 4. The end of the hose workpiece 4 to be coated with glue extends out from the side of the hose conveyor line 1.

[0037] The glue application assembly 2 is located on one side of the hose conveying line 1. The glue application assembly 2 includes a mounting frame 21, a flipping mechanism 23, and a translation mechanism 24. The mounting frame 21 is provided with a number of glue application heads 22, each of which corresponds to a hose workpiece 4. A glue storage tank 25 is provided on one side of the mounting frame 21. The flipping mechanism 23 is used to drive the mounting frame 21 to flip so that the glue application head 22 dips into the glue storage tank 25. The translation mechanism 24 is used to drive the mounting frame 21 to approach the hose workpiece 4 so that the glue application head 22 is inserted into the end of the hose workpiece 4 to be glued and complete the glue application.

[0038] The clamping assembly 3 is located between the hose conveying line 1 and the adhesive application assembly 2. The clamping assembly 3 is used to lock the position of the end of the hose workpiece 4 to be coated with adhesive.

[0039] Thus, the hose workpiece 4 is automatically clamped and coated with glue when it flows to the glue coating station along the hose conveyor line 1. In addition, a glue coating head 22 that can automatically flip to dip and move the glue is designed for the working condition of applying glue to the inner wall of the hose workpiece 4, which improves the level of automated production and meets the connection requirements of the hose workpiece 4 with other components.

[0040] The adhesive used here is preferably cyclohexanone, but not limited to it. Due to its excellent adhesive properties and rapid curing characteristics, cyclohexanone can effectively improve the quality and efficiency of adhesive application, ensure a firm and reliable connection between the hose workpiece 4 and other components, and adapt to various production environment requirements.

[0041] Optionally, the adhesive application assembly 2 also includes a base plate 26 and a movable frame 27. The base plate 26 is provided with a first guide rail arranged toward the hose delivery line 1. The movable frame 27 is mounted on the first guide rail and is driven by the translation mechanism 24 to slide along the first guide rail. The mounting frame 21 is rotatably mounted on the movable frame 27 and is driven by the flipping mechanism 23 to flip relative to the movable frame 27.

[0042] Thus, through the coordinated action of the flipping mechanism 23 and the translation mechanism 24, the glue applicator 22 can move precisely and flexibly to pick up an appropriate amount of glue and apply it evenly to the inner wall of the hose workpiece 4, thereby further improving the glue application quality and efficiency.

[0043] Furthermore, the mounting frame 21 is provided with a number of rotating rods 211, and each glue applicator 22 is installed on the rotating rod 211. Each rotating rod 211 is provided with a first gear 212, and the first gears 212 of adjacent rotating rods 211 mesh with each other. One of the rotating rods 211 is provided with a second gear 213. The mounting frame 21 is provided with a first drive cylinder 214, and the output end of the first drive cylinder 214 is provided with a first rack 215, which meshes with the second gear 213.

[0044] Therefore, when the first drive cylinder 214 drives the first rack 215 to move, the first rack 215 drives the second gear 213 to rotate, and the second gear 213 drives the adjacent first gear 212 to rotate, thereby causing all the glue application heads 22 to rotate synchronously (adjacent glue application heads 22 rotate in opposite directions), ensuring uniform and sufficient glue application and optimizing the automatic glue application process. Under normal circumstances, the first drive cylinder 214 drives the first rack 215 to reciprocate once in one extension and retraction cycle, driving each glue application head 22 to rotate forward and backward once, thus completing one glue application action.

[0045] Optionally, the translation mechanism 24 includes a second drive cylinder 241 fixed on the base plate 26, and the output end of the second drive cylinder 241 is connected to the moving frame 27.

[0046] The first guide rail is arranged along the axial direction of the hose workpiece 4. Thus, the second drive cylinder 241 drives the moving frame 27 to slide along the first guide rail, so that the glue applicator 22 can be accurately fed towards the glue-to-be-applied end of the hose workpiece 4 and can be accurately inserted into the hose workpiece 4 to ensure the glue application effect.

[0047] Optionally, the glue storage tank 25 is fixed on the base plate 26 and located directly below the mounting frame 21. The flipping mechanism 23 includes a third drive cylinder 231 fixed on the movable frame 27. The output end of the third drive cylinder 231 is provided with a second rack 232. The rotating shaft of the mounting frame 21 is provided with a third gear 233. The second rack 232 meshes with the third gear 233. The flipping mechanism 23 is used to drive the glue applicator 22 to stand vertically downward to pick up the glue in the glue storage tank 25, and drive the glue applicator 22 to face the glue-to-be-applied end of the hose workpiece 4 to wait for glue application.

[0048] Therefore, the third drive cylinder 231 drives the second rack 232 to move, which in turn drives the third gear 233 to rotate, causing the mounting bracket 21 and the glue applicator 22 on it to flip, so that the glue applicator 22 can dip glue into the glue storage tank 25. Different angles can control the amount of glue applied, further improving the uniformity and coverage of the glue application.

[0049] Optionally, the glue applicator 22 is provided with an insertion part 221 for inserting into the flexible tube workpiece 4, and the insertion part 221 is provided with a plurality of glue storage grooves 222. See details. Figure 4 The insertion part 221 is designed in a conical shape to facilitate smooth entry into the hose workpiece 4; the design of the glue storage groove 222 facilitates the measurement of glue amount, avoids too much or too little glue, and ensures that the glue applied each time is appropriate and evenly distributed, which helps to improve the glue application quality.

[0050] Optionally, the clamping assembly 3 includes an upper clamping block 32 and a lower clamping block 31. The upper clamping block 32 is provided with a limiting groove 311 for positioning each hose workpiece 4. The lower clamping block 31 is provided with a protrusion 321 that cooperates with each limiting groove 311. The upper clamping block 32 and the lower clamping block 31 cooperate to clamp the end of the hose workpiece 4 to be coated with glue.

[0051] Thus, through the precise cooperation of the limiting groove 311 and the protrusion 321, the hose workpiece 4 is reliably fixed, ensuring that the hose workpiece 4 does not shift during the glue application process. Moreover, the clamping method can quickly clamp and release a batch of hose workpieces 4, which is convenient for matching the operation of the hose conveyor line 1.

[0052] Furthermore, the clamping assembly 3 also includes a fixed vertical plate 33 and a fourth drive cylinder 34. The fixed vertical plate 33 is provided with a second guide rail arranged vertically, and the lower clamping block 31 is slidably disposed on the second guide rail and driven by the fourth drive cylinder 34 to slide along the second guide rail.

[0053] Specifically, a glue receiving groove 39 is provided on the side of the lower clamping block 31 near the glue application component 2. The glue receiving groove 39 is used to collect the glue dripping from the glue application head 22 and the end of the hose workpiece 4 to be glued.

[0054] Therefore, the fourth drive cylinder 34 controls the lower clamping block 31 to move up and down, the second guide rail ensures the stability and accuracy of the movement of the lower clamping block 31, and according to the requirements of the glue dipping action, the glue receiving groove 39 can be installed on the lower clamping block 31, which optimizes the spatial layout, facilitates the collection and cleaning of dripping glue, avoids waste and pollution, improves the cleanliness of the working environment, and ensures that the production process is efficient and environmentally friendly.

[0055] Furthermore, the clamping assembly 3 also includes a suspension 35 and a fifth drive cylinder 36. The fifth drive cylinder 36 is fixed downward on the suspension 35. The output end of the fifth drive cylinder 36 is connected to the upper clamping block 32. The upper clamping block 32 is provided with a guide post 37, and the suspension 35 is provided with a guide sleeve 38 that cooperates with the guide post 37.

[0056] Therefore, the fifth drive cylinder 36 drives the upper clamping block 32 to move up and down, and the precise cooperation between the guide post 37 and the guide sleeve 38 ensures the smoothness and accuracy of the movement of the upper clamping block 32, further improving the clamping stability.

[0057] Specific action process:

[0058] 1) A batch of hose workpieces 4 arrive at the glue application station along the hose conveyor line 1. The glue application heads 22 corresponding to the multiple hose workpieces 4 are initially aligned with the glue-to-apply ends of each hose workpiece 4 and maintain an appropriate distance.

[0059] 2) The fourth drive cylinder 34 and the fifth drive cylinder 36 of the clamping assembly 3 are activated respectively, controlling the upper clamping block 32 and the lower clamping block 31 to cooperate and clamp the ends of multiple hose workpieces 4 to be coated with glue at the same time.

[0060] 3) The third drive cylinder 231 of the flipping mechanism 23 drives the second rack 232 to move, which in turn drives the third gear 233 to rotate, thereby driving multiple glue application heads 22 to flip and dip into the glue storage tank 25.

[0061] 4) After the glue applicator 22 has absorbed an appropriate amount of glue, the glue applicator 22 returns to its initial position;

[0062] 5) The second drive cylinder 241 of the translation mechanism 24 drives the mounting bracket 21 to translate along the first guide rail, so that multiple glue application heads 22 are simultaneously inserted into the glue-to-be-applied ends of the corresponding hose workpieces 4 to apply glue.

[0063] 6) After the glue application is completed, the glue application head 22 returns to its initial position;

[0064] 7) The upper clamping block 32 and the lower clamping block 31 release the ends of multiple hose workpieces 4 that are to be coated with glue, and the hose workpieces 4 that have completed the coating leave the coating station along the conveyor line.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
