[0033] Please refer to Figures 1-5 This utility model provides a glue dispensing and conveying connection structure, which includes a first glue dispensing conveying head 10, a second glue dispensing conveying head 20, and a glue dispensing head 30. The glue dispensing head 30 can be the glue dispensing part of a two-component glue cartridge. The glue dispensing head 30 connects glue cartridge A and glue cartridge B, and has a first glue dispensing channel 31 and a second glue dispensing channel 32 inside. The first glue dispensing channel 31 is used for dispensing glue from glue cartridge A, and the second glue dispensing channel 32 is used for dispensing glue from glue cartridge B.
[0034] To enable quick assembly and disassembly of the first dispensing conveyor head 10, the second dispensing conveyor head 20, and the dispensing head 30, the dispensing conveying connection structure further includes a connecting housing 40 and an inner connecting body 50. The connecting housing 40 is threadedly connected to the outer circumference of the dispensing head 30. One end of the inner connecting body 50 is inserted into the first dispensing conveyor head 10 and the second dispensing conveyor head 20, and the other end of the inner connecting body 50 is inserted into the dispensing head 30.
[0035] Specifically, the inner connector 50 is rotatably disposed in the connecting housing 40. The inner connector 50 includes a connecting body 57, a first plug 53 and a second plug 54. One end of the inner connector 50 is provided with a first insertion hole 51 and a second insertion hole 52. The first insertion hole 51 can be inserted into the first dispensing conveyor head 10, and the second insertion hole 52 can be inserted into the second dispensing conveyor head 20. The first plug 53 and the second plug 54 are disposed at the other end of the inner connector 50. The first plug 53 can be inserted into the first dispensing channel 31, and the second plug 54 can be inserted into the second dispensing channel 32. The first plug 53 is provided with a first liquid inlet 531, the second plug 54 is provided with a second liquid inlet 541, the inner connector 50 is also provided with a first connecting channel 55 connecting the first socket 51 and the first liquid inlet 531, so as to transport the glue in the glue tube A to the first glue dispensing conveyor head 10, and the inner connector 50 is also provided with a second connecting channel 56 connecting the second socket 52 and the second liquid inlet 541, so as to transport the glue in the glue tube B to the second glue dispensing conveyor head 20.
[0036] In this embodiment, the first dispensing head 10 can be inserted into the first socket 51, and the second dispensing head 20 can be inserted into the second socket 52. Then, the inner connector 50 can be inserted into the inner circumference of the dispensing head 30, and the connecting shell 40 can be rotated and threaded onto the outer circumference of the dispensing head 30. This completes the assembly of the first dispensing head 10, the second dispensing head 20, and the dispensing head 30. When replacing the two-component glue cartridge in the future, only simple rotation and insertion / removal actions are required. The assembly and disassembly processes are very simple and time-consuming.
[0037] In addition, an inner connector 50 is used to connect the dispensing head 30 to the first dispensing conveyor head 10 and the second dispensing conveyor head 20, so that even if the dispensing conveyor head and the dispensing head 30 are of different models, they can be easily and stably connected together.
[0038] In a preferred embodiment, the connecting housing 40 includes a receiving portion 41 and a connecting portion 42. The connecting body 57 is located in the receiving portion 41. When the inner circumference of the connecting portion 42 is threadedly connected to the outer circumference of the dispensing head 30, the first plug 53 and the second plug 54 both partially extend into the connecting portion 42.
[0039] In a preferred embodiment, to avoid leakage of adhesive due to dimensional errors between the first plug 53 and the first adhesive outlet channel 31 and / or the second plug 54 and the second adhesive outlet channel 32, a first sealing ring 60 is also provided in the receiving part 41. The first sealing ring 60 is located between the connecting body 57 and the connecting part 42, and the first plug 53 and the second plug 54 are located on the inner periphery of the first sealing ring 60.
[0040] Preferably, refer to Figure 3Let s be the distance between the connecting body 57 and the dispensing head 30, and d be the thickness of the first sealing ring 60. When the first plug 53 is not inserted into the first dispensing channel 31, the relationship s > d is satisfied. In this embodiment, as the first plug 53 and the second plug 54 are inserted, the distance between the connecting body 57 and the dispensing head 30 can gradually decrease until the connecting body 57 and the first sealing ring 60 are in close contact, at which point s = d.
[0041] In a preferred embodiment, a gap is provided between the connecting body 57 and the receiving part 41 to facilitate relative rotation between them.
[0042] Furthermore, to prevent the adhesive from leaking out from the gap between the connecting body 57 and the receiving part 41, a second sealing ring 70 is provided in the receiving part 41. The second sealing ring 70 is located on the side of the connecting body 57 away from the first sealing ring 60.
[0043] Furthermore, the inner wall of the receiving part 41 is provided with a receiving groove 411, and the second sealing ring 70 is partially received in the receiving groove 411. In this embodiment, when the connecting housing 40 is rotated and brought closer to the two-component glue cartridge, the second sealing ring 70 can be driven to press against the connecting body 57, so that the first plug 53 extends further into the first glue dispensing channel 31, and the second plug 54 extends further into the second glue dispensing channel 32. Therefore, during operation, after aligning the first plug 53 with the first glue dispensing channel 31 and the second plug 54 with the second glue dispensing channel 32, a tight assembly with the glue dispensing head 30 on the two-component glue cartridge can be achieved by rotating the connecting housing 40.
[0044] In a preferred embodiment, to enhance the synchronous linkage between the inner connector 50 and the connecting housing 40, the second sealing ring 70 is fixedly connected to the inner connector 50. Specifically, refer to... Figure 4 and Figure 5 The second sealing ring 70 has an opening 71, and the second sealing ring 70 has a connecting hole 72 on each side of the opening 71. The connecting hole 72 is used to install fasteners to fix the second sealing ring 70 and the inner connecting body 50.
[0045] In a preferred embodiment, for ease of installation of the second sealing ring 70, refer to Figure 5 When viewed along the direction in which the first dispensing conveyor head 10 is inserted into the first insertion hole 51, the outer periphery of the connecting body 57 is provided with multiple cut surfaces 571.
[0046] In a preferred embodiment, reference may be made to Figure 3 and Figure 4The inner circumference of the dispensing head 30 is provided with a partition plate 33, which separates the first dispensing channel 31 and the second dispensing channel 32. A connecting groove 58 is formed between the first plug 53 and the second plug 54. When the first plug 53 is inserted into the first dispensing channel 31 and the second plug 54 is inserted into the second dispensing channel 32, the partition plate is inserted into the connecting groove 58.
[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
