Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown in the figure, the embodiments of this application disclose an AB glue pneumatic glue injection valve, including a mounting plate 1 and a cylinder fixing plate 2. The cylinder fixing plate 2 is connected to the mounting plate 1. A cylinder 3 is provided on the cylinder fixing plate 2. A glue fixing fixture is provided at the output end of the cylinder 3. An A glue cylinder 4 and a B glue cylinder 5 are provided inside the glue fixing fixture. A first push rod 6 extending into the A glue cylinder 4 and a second push rod 7 extending into the B glue cylinder 5 are provided at the output end of the cylinder 3. A glue outlet connector 8 is provided at the glue outlet of the A glue cylinder 4 and the B glue cylinder 5. An A glue channel 9 and a B glue channel 10 are provided inside the glue outlet connector 8. The A glue channel 9 is connected to the bottom of the A glue cylinder 4, and the B glue channel 10 is connected to the bottom of the B glue cylinder 5. A mixing tube 11 is provided at the output end of the glue outlet connector 8. The valve assembly 12 is also included. The valve assembly 12 is connected to the output end of the mixing tube 11 and is connected to the mounting plate 1.

[0021] It should be explained that the injection valve assembly 12 and the mixing tube 11 in this structure are both existing products and can be directly purchased from outside.

[0022] Specifically, during the dispensing operation, cylinder 3 drives the first push rod 6 and the second push rod 7 to press down the glue in glue cylinder A 4 and glue cylinder B 5. The glue is squeezed into glue channel A 9 and glue channel B 10 respectively, and flows into the mixing tube 11 from glue channel A 9 and glue channel B 10. The mixing operation is carried out in the mixing tube 11. After the mixing is completed, the mixed glue enters the spray valve assembly 12 and is sprayed onto the product through the spray valve assembly 12.

[0023] In this structure, the cylinder 3, the first push rod 6 and the second push rod 7 are configured so that the A glue and B glue can be pressed into the mixing tube simultaneously by a single cylinder 3, thereby reducing the need for a drive mechanism and making the overall structure simpler. At the same time, the spray valve in this structure makes the sprayed glue more uniform and precise.

[0024] In this embodiment, a connecting block 13 is also included, which is installed on the mounting plate 1. The connecting block 13 is provided with a mounting groove for the mixing tube 11 to pass through. A cooling chip 14 is installed in the connecting block 13. A cooling circulation block 15 connected to the cooling chip 14 is provided on one side of the cooling chip 14.

[0025] Specifically, since heat is generated when the glue is mixed in the mixing tube 11, the cooling plate 14 is set to cool the mixing tube 11, thereby preventing the glue from curing due to excessive temperature inside the mixing tube and ensuring the fluidity of the glue.

[0026] In this embodiment, a first pressure sensor 16 and a second pressure sensor 17 are respectively provided on both sides of the glue outlet connector 8. The detection end of the first pressure sensor 16 extends into the A glue channel 9, and the detection end of the second pressure sensor 17 extends into the B glue channel 10.

[0027] Specifically, when the adhesive flows smoothly in the A adhesive channel 9 or the B adhesive channel 10, the first pressure sensor 16 and the second pressure sensor 17 will detect normal pressure values. When the A adhesive channel 9 or the B adhesive channel 10 is blocked, the first pressure sensor 16 or the second pressure sensor 17 will detect an increase in pressure and then issue an alarm. When the operator detects the pressure alarm, the adhesive tube can be disassembled so that the device can be restored to normal operation as soon as possible.

[0028] In this embodiment, a height adjustment mechanism is provided between the mounting plate 1 and the cylinder fixing plate 2. The height adjustment mechanism includes a slide rail 18 obliquely arranged on the mounting plate 1, a slide rail fixing block 19 that can slide along the slide rail 18, a guide rail clamp 20 on the slide rail fixing block 19, and the slide rail fixing block 19 is connected to the cylinder fixing plate 2.

[0029] Specifically, when it is necessary to disassemble the glue cartridge or mixing tube, the height of the cylinder 3 needs to be adjusted. The specific operation is as follows: disconnect the glue outlet connector 8, loosen the guide rail clamp 20, and manually pull the slide rail fixing block 19, thereby driving the cylinder 3 to move obliquely upward, thus leaving space for disassembly of the lower structure, thereby realizing the disassembly of the glue cartridge or mixing tube. When it is necessary to assemble, manually pull the cylinder 3 back to the original position, and then fix the slide rail fixing block 19 with the guide rail clamp 20, thereby realizing the fixation of the cylinder 3.

[0030] Meanwhile, in this structure, by setting the return angle, the cylinder 3 can also move in an upward direction when the bottom structure is disassembled, thus facilitating the replacement of the lower structure.

[0031] In this embodiment, the glue fixing fixture includes a left half fixture 21 and a right half fixture 22. When the left half fixture 21 and the right half fixture 22 are molded together, cavities for positioning the A glue cylinder 4 and the B glue cylinder 5 are formed inside the left half fixture 21 and the right half fixture 22. A hinge 23 is provided at one side of the connection between the left half fixture 21 and the right half fixture 22, and a locking device 24 is provided at the other side of the connection between the left half fixture 21 and the right half fixture 22. The upper end of the left half fixture 21 or the right half fixture 22 is connected to the cylinder fixing plate 2.

[0032] Specifically, when installing A-tube 4 and B-tube 5, first assemble A-tube 4 and B-tube 5 with the first push rod 6 and the second push rod 7, then close the left half-motor fixture 21 and the right half-motor fixture 22, and lock them with the locking device 24 to achieve the positioning of A-tube 4 and B-tube 5. When it is necessary to disassemble A-tube 4 and B-tube 5, first open the locking device 24 to separate the left half-motor fixture 21 and the right half-motor fixture 22, and then disassemble A-tube 4 and B-tube 5.

[0033] The aforementioned glue fixing fixture can position glue tube A 4 and glue tube B 5. At the same time, the hinge 23 and locking device 24 can facilitate the disassembly and replacement of glue tube A 4 and glue tube B 5.

[0034] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
