Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This utility model provides a glue application structure with a split wide flat nozzle. After the split wide flat nozzle 6 is installed on the positioning connector 5, it always maintains the correct position and angle, and the positioning is accurate. Moreover, the split wide flat nozzle 6 is detachably connected into one piece by two separate parts 61, and the residual glue is easy to clean and easy to reuse.

[0030] Please refer to this as well. Figures 1 to 6 The adhesive coating structure with split wide flat nozzle provided by this utility model includes:

[0031] Mixing hose 1, the outer sleeve of the mixing hose 1 is provided with a sheath tube 2, the outer sleeve of the sheath tube 2 is provided with a positioning tube 3, and the positioning tube 3 is clamped and fixed by a clamping positioning element 4;

[0032] The positioning connector 5 has a split wide flat nozzle 6 detachably connected to one end, and two limiting posts 501 provided at the other end. The split wide flat nozzle 6 is connected to one end of the mixing tube 1. The split wide flat nozzle 6 includes two split parts 61 that are detachably connected as one piece.

[0033] Among them, the positioning tube 3 is provided with two limiting grooves 301 at one end near the split wide flat nozzle 6, and two limiting posts 501 are inserted into the two limiting grooves 301 respectively. The positioning connector 5 is fixedly connected to the positioning tube 3 by fasteners 7.

[0034] The sheath tube 2 protects the mixing hose 1 from external environmental interference, ensuring its stable operation. Specifically, the sheath tube 2 is made of high-strength, wear-resistant material to withstand the pressure and friction during operation.

[0035] The mixing tube 1 is fitted inside the sheath tube 2, and the sheath tube 2 is at least partially fitted inside the positioning tube 3. The positioning tube 3 is fixed by clamping the positioning member 4. The two limiting posts 501 of the positioning tube 3 are inserted into the two limiting grooves 301 of the positioning connector 5 and then connected by fasteners 7. The split-width flat nozzle 6 is detachably connected to the positioning connector 5. One end of the mixing tube 1 is connected to the split-width flat nozzle 6. When in use, the glue is injected from the other end of the mixing tube 1. After passing through the mixing tube 1, the glue enters the split-width flat nozzle 6 through the inlet end and finally exits through the outlet end.

[0036] After the positioning tube 3 is clamped and fixed by the clamping positioning piece 4, the positioning tube 3 cannot rotate. After the positioning tube 3 is connected to the positioning connector 5 by the fastener 7, the positioning connector 5 cannot rotate because the two limiting posts 501 are respectively set in the two limiting grooves 301. As a result, the split wide flat nozzle 6 installed on the positioning connector 5 cannot rotate, thus ensuring the stability and reliability of the entire system. After the split wide flat nozzle 6 is installed, it always maintains the correct position and angle, and the glue dispensing direction and height are consistent. The positioning is accurate, which facilitates the accurate delivery of glue and ensures product quality.

[0037] Furthermore, the split wide flat nozzle 6 is composed of two separate parts 61 that can be detachably connected as one unit. After the glue is applied, the split wide flat nozzle 6 can be disassembled into two separate parts 61. The glue residue inside the split wide flat nozzle 6 is easy to clean. After cleaning, it can be reconnected as one unit, which is convenient for reuse and reduces costs.

[0038] In some embodiments, please refer to the following: Figure 1 , Figure 2 and Figure 4 The positioning connector 5 has a first limiting step 502 near the end of the split wide flat nozzle 6. The first limiting step 502 has a notch 503 on one side for the split wide flat nozzle 6 to pass through. The split wide flat nozzle 6 has a second limiting step 62. The split wide flat nozzle 6 abuts against the first limiting step 502 of the positioning connector 5 through the second limiting step 62.

[0039] When the split-width flat nozzle 6 is installed on the positioning connector 5, the split-width flat nozzle 6 enters the positioning connector 5 through the notch 503. The second limiting step 62 of the split-width flat nozzle 6 abuts against the first limiting step 502 of the positioning connector 5, thereby achieving the positioning and installation of the split-width flat nozzle 6. After installation, the split-width flat nozzle 6 cannot rotate. When the adhesive application is completed and the split-width flat nozzle 6 needs to be removed, it can be removed through the notch 503 of the positioning connector 5.

[0040] With this setup, the connection between the split-width flat nozzle 6 and the positioning connector 5 is not only convenient, but also the position and angle of the split-width flat nozzle 6 remain consistent after each installation, ensuring accurate repositioning.

[0041] In some embodiments, please refer to the following: Figures 1 to 2 Fastener 7 is a locking nut. The positioning tube 3 and the positioning connector 5 are both provided with external threads at their close ends. The locking nut is threadedly connected to the positioning tube 3 and the positioning connector 5 through the external threads.

[0042] After the two limiting posts 501 of the positioning connector 5 are inserted into the two limiting grooves 301 of the positioning tube 3, the end of the positioning tube 3 is connected to the end of the positioning connector 5. The locking nuts are threadedly connected to the positioning tube 3 and the positioning connector 5 respectively, thereby achieving a stable connection between the positioning tube 3 and the positioning connector 5.

[0043] In some embodiments, please refer to the following: Figures 1 to 3 The positioning tube 3 is fitted with and fixed with a retaining ring 302, which is used to abut against one side of the locking nut.

[0044] The positioning tube 3 has a mounting groove along its outer circumference. The mounting groove is provided with an external thread near the end of the positioning tube 3. The retaining ring 302 is engaged in the mounting groove. After the locking nut is tightened, one side of the locking nut abuts against the retaining ring 302. The retaining ring 302 can position the locking nut, ensuring that the locking nut is simultaneously connected to the positioning tube 3 and the positioning connector 5, thus ensuring a reliable connection.

[0045] In some embodiments, please refer to the following: Figure 1 , Figure 2 and Figure 5 The split component 61 is provided with an inlet groove 611, a connecting groove 612, a transition groove 613 and an outlet groove 614 connected in sequence. When the two split components 61 are connected as one unit, the inlet groove 611, the connecting groove 612, the transition groove 613 and the outlet groove 614 of the two split components 61 are correspondingly spliced ​​to form a sealed channel.

[0046] The inlet groove 611, connecting groove 612, transition groove 613, and outlet groove 614 are located on the side of the two separate components 61 that are close to each other. After the two separate components 61 are assembled and connected, the inlet groove 611, connecting groove 612, transition groove 613, and outlet groove 614 of the two separate components 61 form a sealed channel. The end of the inlet groove 611 is the inlet end of the split wide flat nozzle 6, and the end of the outlet groove 614 is the outlet end of the split wide flat nozzle 6. After the mixing tube 1 is connected to the split wide flat nozzle 6, the glue enters the split wide flat nozzle 6 from the end of the inlet groove 611, passes through the connecting groove 612 and the transition groove 613 in sequence, and is discharged from the end of the outlet groove 614, thus completing the glue application.

[0047] Optionally, in order to ensure the sealing effect of the split-width flat nozzle 6, the split component 61 can be provided with a sealing strip. The sealing strip is located on both sides of the inlet groove 611, the connecting groove 612, the transition groove 613 and the outlet groove 614 of the split component 61. When the split components 61 are connected as one piece, the sealing strip seals the gap between the split components 61 to prevent glue from leaking from the gap between the two split components 61.

[0048] In some embodiments, please refer to Figure 5The size of the outlet groove 614 gradually increases from the side closer to the inlet groove 611 to the side farther away from the inlet groove 611.

[0049] Specifically, in this embodiment, the cross-sectional shape of the outlet groove 614 is an isosceles trapezoid, and the size of the outlet groove 614 gradually increases from the side closer to the inlet groove 611 to the side farther away from the inlet groove 611, which facilitates the discharge of glue.

[0050] In some embodiments, please refer to the following: Figure 1 , Figure 2 and Figure 5 The two separate components 61 are connected by bolts. Connecting the two separate components 61 by bolts not only ensures a reliable connection, but also facilitates subsequent disassembly and cleaning.

[0051] In some embodiments, please refer to Figure 2 The mixing hose 1 has an annular groove 101 at one end for connecting to the split wide flat nozzle 6, and a sealing ring is provided in the annular groove 101.

[0052] After the mixing tube 1 is connected to the split wide flat nozzle 6, one end of the mixing tube 1 extends into the interior of the split wide flat nozzle 6. By setting a sealing ring, a relative seal can be formed between the mixing tube 1 and the split wide flat nozzle 6, preventing glue from leaking from the gap between the mixing tube 1 and the split wide flat nozzle 6 and ensuring the sealing effect.

[0053] In some embodiments, please refer to the following: Figures 1 to 2 The positioning connector 5 has an annular step 504 inside. One end of the sheath tube 2 extends into the positioning connector 5 and abuts against the annular step 504. This arrangement enables the sheath tube 2 to be positioned.

[0054] In some embodiments, please refer to the following: Figure 1 , Figure 2 and Figure 6 The clamping and positioning component 4 includes a positioning plate 41 and a fastening clamp 42 fixedly disposed on the positioning plate 41. The fastening clamp 42 has a clamping hole 421 in the middle for accommodating the positioning tube 3, and the two sides of the fastening clamp 42 are fastened together by bolts.

[0055] The positioning plate 41 and the fastening clamp 42 are arranged perpendicularly. The fastening clamp 42 can be fixedly connected to the positioning plate 41 by bolts, and the positioning plate 41 can be installed on the fixed bracket by pins or the like. When the fastening clamp 42 is used to clamp and fix the positioning tube 3, the positioning tube 3 is accommodated in the clamping hole 421 of the fastening clamp 42, and the bolts pass through both sides of the fastening clamp 42 in sequence and are locked and fixed by nuts, so that the positioning tube 3 can be reliably clamped.

[0056] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0057] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
