[0030] Example 1

[0031] Reference Figure 1 to Figure 6 , which is the first embodiment of the present invention, provides a glue filling nozzle, which includes a glue spraying unit 1, including a mixing cylinder 11 and a first glue outlet cylinder 12 and a second glue outlet cylinder 13 symmetrically fixed on both sides thereof, the first glue outlet cylinder 12 is connected to the inner cavity of the second glue outlet cylinder 13, and a nozzle 14 is also fixed on the mixing cylinder 11.

[0032] The first glue cylinder 12 and the second glue cylinder 13 have the same structure and store two kinds of colloids inside. The glue outlets of the first glue cylinder 12 and the second glue cylinder 13 on both sides are connected to the inner cavity of the mixing cylinder 11, and the finished glue after mixing is finally discharged from the nozzle 14.

[0033] The rubber mixing unit 2 comprises a rotating piston rod 21 and a rubber sealing ring 22 , a rubber blocking ring 23 and a leak-proof member 24 fixed to the outside of the rotating piston rod 21 in sequence. The rubber sealing ring 22 , the rubber blocking ring 23 and the leak-proof member 24 are all movably arranged in the inner cavity of the mixing cylinder 11 .

[0034] The rubber blocking ring 23 and the leak-proof member 24 are main stirring components for mixing the two colloids, ensuring that the two colloids are fully mixed and then discharged from the nozzle 14 .

[0035] The driving unit 3 includes a glue pushing cylinder 31 and a rotating cylinder 32 . The glue pushing cylinder 31 is fixed to the first glue outlet cylinder 12 and the second glue outlet cylinder 13 , respectively. The rotating cylinder 32 is fixed to the mixing cylinder 11 and is fixed to the rotating piston rod 21 .

[0036] The top of the mixing cylinder 11 is fixedly connected to the rotating cylinder 32 , and a mixing chamber A is provided in the middle of the bottom end of the mixing cylinder 11 , and an external thread W is provided on the outer wall of the bottom end of the mixing cylinder 11 .

[0037] Furthermore, the rotating cylinder 32 is also prior art. The piston rod of the rotating cylinder 32 can rotate circumferentially while performing linear motion. The rotating piston rod 21 can serve as the piston rod of the rotating cylinder 32, and can also be fixedly connected to the piston rod of the rotating cylinder 32 to achieve the purpose of synchronous movement and rotation.

[0038] The first glue outlet cylinder 12 and the second glue outlet cylinder 13 are connected to the mixing chamber A through a mixing pipe B. A pressure pump B1 is connected and fixed to the mixing pipes B on both sides.

[0039] During use, the pressure pump B1 can apply pressure to the mixing tube B to accelerate the flow of the colloid inside the mixing tube B.

[0040] The glue pushing cylinder 31 is fixedly connected to the top of the first glue outlet cylinder 12 and the second glue outlet cylinder 13 , and the piston push rod of the glue pushing cylinder 31 is slidably inserted into the glue storage cavity of the first glue outlet cylinder 12 and the second glue outlet cylinder 13 .

[0041] Furthermore, the glue pushing cylinder 31 is a standard cylinder in the prior art, and its end piston rod performs linear motion. The piston rod slides and inserts into the first glue outlet cylinder 12 and the second glue outlet cylinder 13, squeezing downward the two groups of colloids stored in the first glue outlet cylinder 12 and the second glue outlet cylinder 13, so that the colloids enter the mixing cylinder 11.

[0042] Example 2

[0043] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the rotating piston rod 21 is rotatably inserted into the top of the mixing cylinder 11, the rotating piston rod 21 includes a rotating rod 211 and a docking rod 212, the top of the rotating rod 211 is fixedly connected to the output end of the rotating cylinder 32, the rotating piston rod 21 is controlled by the rotating cylinder 32, and the functions of rotation and linear movement are realized at the same time.

[0044] A plurality of sliding grooves 2111 are circumferentially provided on the outer wall at the bottom end of the rotating rod 211, and a lower push ring 2112 is fixed to the outer wall at the bottom end of the rotating rod 211. A screw rod 2121 is fixedly connected to the middle part of the top end of the docking rod 212. A locking groove 2122 is provided in the middle part of the bottom end of the docking rod 212, and the screw rod 2121 is threadedly inserted into the rotating rod 211.

[0045] The sliding groove 2111 extends along the outer wall of the rotating rod 211 to the end of the sliding groove 2111 . When the docking rod 212 is rotated and installed to the bottom end of the rotating rod 211 , the docking rod 212 blocks one end of the sliding groove 2111 .

[0046] It should be noted that the rotation direction of the rotary piston rod 21 controlled by the rotary cylinder 32 is opposite to the direction in which the screw rod 2121 is threadedly inserted into the rotary rod 211, that is, when the rotary piston rod 21 rotates, the screw rod 2121 is more tightly connected to the rotary rod 211.

[0047] The sealing ring 22 can be coaxially fixed in the mixing chamber A, and the sealing ring 22 is sleeved outside the rotating piston rod 21 . The sealing ring 22 includes a top ring 221 , a first spring T1 , a sealing ring 223 and a pushing ring 224 .

[0048] Both ends of the first spring T1 are fixedly connected to the top ring 221 and the sealing ring 223 , and the top ring 221 is detachably fixed to the inner wall of the top end of the mixing chamber A.

[0049] A sealing pad 2231 is coaxially fixed to the bottom edge of the sealing ring 223 , and the rubber push ring 224 is coaxially fixedly connected to the bottom of the sealing ring 223 .

[0050] When the first spring T1 is in a naturally straightened state, the rubber push ring 224 is just above the opening of the mixing tube B on the inner wall of the mixing chamber A.

[0051] A plurality of groups of slide grooves 2241 are circumferentially formed on the top of the rubber pushing ring 224 , and the plurality of groups of slide grooves 2241 are simultaneously oriented toward the axis of the rubber pushing ring 224 .

[0052] A second spring T2 is fixedly connected to the inner wall of the sliding groove 2241 on one side away from the axis of the push rubber ring 224. A block 2242 is also slidably connected in the sliding groove 2241. The other end of the second spring T2 is fixed to the block 2242. The block 2242 can be slidably inserted into the sliding groove 2111. A push plate 2243 is also fixedly connected to the top of the block 2242.

[0053] During use, the rubber push ring 224 is first sleeved onto the outside of the rotating rod 211, and the components such as the nozzle 14, the rubber blocking ring 23 and the leak-proof part 24 are not installed yet. At this time, the push plate 2243 is pushed outward through the gap of the first spring T1, and the push plate 2243 drives the second spring T2 to contract. At this time, the inner diameter of the middle hole of the rubber push ring 224 is equal to the outer diameter of the rotating rod 211, and the rotating rod 211 is just inserted into the sliding groove 2111.

[0054] Furthermore, the push plate 2243 is released, and the block 2242 has a tendency to return outward under the action of the second spring T2. At this time, the push rubber ring 224 is slightly turned to rotate the rotating piston rod 21 until it can be inserted into the sliding groove 2111. At this time, the second spring T2 is completely reset.

[0055] During use, when the rotating piston rod 21 moves linearly, it is necessary to ensure that after the rotating piston rod 21 moves to the lowest end, after the two colloids enter the mixing chamber A, the mixed colloids will not push the rubber push ring 224 upward. At this time, the block 2242 always maintains this height under the limiting action of the sliding groove 2111.

[0056] The purpose of maintaining the height of the rubber push ring 224 is to ensure that the two colloids are always located at the discharge port of the mixing tube B, which is the main place for mixing the rubbers. Therefore, accumulating the two colloids here can ensure that the colloids are fully mixed.

[0057] A mixing barrel 231 and a conical glue discharging barrel 232 are coaxially fixed to the bottom end of the glue blocking ring 23 , and a separation ring 233 is also fixedly connected to the connection between the mixing barrel 231 and the conical glue discharging barrel 232 .

[0058] The top of the rubber blocking ring 23 is provided with a slope surface X, the middle of the rubber blocking ring 23 is further provided with a lower glue hole K, and a plurality of groups of glue flow grooves X1 are circumferentially provided on the slope surface X, and the glue flow grooves X1 are in a spiral shape.

[0059] During use, the two colloids can converge along the glue flow groove X1 to the middle of the lower glue hole K and initially mix and contact in the lower glue hole K.

[0060] Inner holes 234 are symmetrically formed on the outer walls of the rubber blocking ring 23 on both sides opposite to each other. A piston 2341 is slidably inserted into the inner hole 234 . A third spring T3 is fixedly connected between the piston 2341 and the inner hole 234 .

[0061] The piston 2341 can be inserted into the mixing tube B in a sealing manner, and an arc surface X2 is formed on the edge of one end of the piston 2341 away from the third spring T3.

[0062] During use, when there is no need to mix or pour glue, the piston 2341 is inserted into the mixing tube B to block the nozzle of the mixing tube B. At the same time, the glue blocking ring 23 also blocks the mixing chamber A located below the nozzle of the mixing tube B, thereby preventing leakage of the two colloids.

[0063] When mixing and pouring glue is needed, the rotating piston rod 21 rotates and moves downward, the lower push ring 2112 pushes the glue blocking ring 23 downward from the top, the mixing tube B slides and squeezes the arc surface X2, and the piston 2341 shrinks into the embedded hole 234. At this time, the nozzle of the mixing tube B is exposed, and the two colloids flow out.

[0064] The spray head 14 includes a nut 141 and a conical nozzle 142 coaxially fixed at the bottom end thereof. An abutment platform 143 is coaxially fixed at the connection between the nut 141 and the conical nozzle 142 .

[0065] The nut 141 can be threadedly sleeved on the outside of the external thread W. A fourth spring T4 is fixedly connected to the top of the abutment platform 143 , and the other end of the fourth spring T4 is fixedly connected to a groove formed at the bottom end of the rubber blocking ring 23 .

[0066] When there is no need to mix or pour glue, the fourth spring T4 pushes the glue blocking ring 23 upward to maintain the natural height of the glue blocking ring 23, so that the piston 2341 is inserted into the mixing tube B.

[0067] A plurality of groups of vertical plates 144 are circumferentially fixedly connected to the bottom opening of the conical nozzle 142, and a sealing platform 145 is fixedly connected to the top of the vertical plate 144, and the sealing platform 145 can cooperate with the top opening of the sealing separation ring 233; a glue outlet gap C is formed between the vertical plates 144, and the finished glue flows out from the glue outlet gap C and is finally sprayed out from the opening of the conical nozzle 142.

[0068] The leak-proof part 24 includes a mesh cover 241 and a mixing ring 242 fixed on the top thereof. The mesh cover 241 has an opening at the top, and a glue storage space D is formed inside. A docking column 243 is fixedly connected to the bottom of the glue storage space D, and a docking block 2431 is fixedly connected to the top of the docking column 243. The docking block 2431 is inserted and engaged in the engagement groove 2122.

[0069] The mixing ring 242 has an opening in the middle to form a lower leakage hole 2421 . A stirring rod 2422 is fixed on the mixing ring 242 around the lower leakage hole 2421 . The stirring rod 2422 can rotate in the lower glue hole K.

[0070] During use, when glue mixing and glue pouring are required, the rotating piston rod 21 rotates and moves downward, and the docking block 2431 is inserted and engaged in the engaging groove 2122, so that the leakage-proof part 24 rotates as a whole along with the rotating piston rod 21.

[0071] When the leak-proof part 24 rotates, the stirring rod 2422 rotates in the lower glue hole K. At the same time, the lower push ring 2112 also rotates synchronously. The stirring rod 2422 and the lower push ring 2112 doubly stir the two colloids. The two colloids after stirring fall into the glue storage space D and penetrate into the mixing barrel 231 from the mesh holes of the mesh cover 241. Then the finished glue enters the conical glue outlet barrel 232 from the hole opened in the middle of the separating ring 233, and is finally sprayed out from the glue outlet gap C and the opening of the conical nozzle 142.

[0072] When there is no need to mix or pour glue, the rotating piston rod 21 stops rotating and retracts. At this time, the fourth spring T4 is reset and pushes the glue blocking ring 23 upward. At this time, the separating ring 233 gradually approaches the sealing platform 145. Finally, the middle opening of the separating ring 233 is completely blocked by the sealing platform 145. At the same time, the piston 2341 is inserted into the mixing tube B to block the pipe opening of the mixing tube B.

[0073] The remaining structures are the same as those of Example 1.

[0074] Example 3

[0075] Reference Figure 1 to Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that it provides a method for using a glue pouring nozzle for a car cylinder wiring harness, which is applicable to the glue pouring nozzle in the above embodiment; and comprises the following steps:

[0076] In the initial state, the first glue outlet cylinder 12 and the second glue outlet cylinder 13 are filled with two mixed glues with different components, and the rotary cylinder 32 controls the rotary piston rod 21 to be lifted to the highest point.

[0077] When preparing to inject glue, the rotary cylinder 32 controls the rotary piston rod 21 to rotate and slowly pushes the rotary piston rod 21 downward, and at the same time controls the glue pushing cylinder 31 to inject the two mixed glues into the mixing cylinder 11.

[0078] The two mixed glues are stirred and fully mixed by the glue blocking ring 23 and the leak-proof member 24 , and finally discharged from the nozzle 14 .

[0079] During use, the pressure pump B1 can apply pressure to the mixing tube B. As time goes by, the pressure in the mixing chamber A gradually increases, so that the finished glue mixed in the mixing chamber A can be sprayed out from the conical nozzle 142 more smoothly.

[0080] When the glue injection is almost completed, the rotating piston rod 21 can be controlled to rotate and retract until it is lifted to the highest position. During this process, some finished glue still remains in the conical glue discharge barrel 232. These residual finished glue can be poured outside the wiring harness. After knowing that the conical nozzle 142 will no longer discharge glue, the glue pushing cylinder can be closed and the conical nozzle 142 can be wiped clean.

[0081] Furthermore, the seal formed by the separation ring 233 and the sealing platform 145 can ensure that the residual finished glue in the glue storage space D will not leak, thereby avoiding the occurrence of glue dripping.

[0082] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
