Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive machine technology, and more specifically, it relates to a hot melt adhesive machine for precise hot melt adhesive extrusion. Background Technology

[0002] Hot melt adhesive machines are automated application equipment mainly used for hot melt adhesive spraying, scraping, rolling, coating, and injection. They are widely used in household products (diapers, sanitary napkins, mousetraps, cockroach traps, and other disposable products), the automotive industry (interior sealing, headlight manufacturing, windshield assembly, air filters, non-woven fabric lamination, footwear, printing, electronic product assembly, clothing, self-adhesive labels), the packaging industry (carton packaging, cigarette box packaging, Tetra Pak beverage packaging), the coating and laminating industry (trademark paper, double-sided label tape, medical breathable tape), bookbinding, and other industries.

[0003] However, traditional hot melt glue machines lack a heating mechanism, which makes it easy for the glue to carbonize in the storage tank, resulting in inaccurate dispensing and consequently, poor quality of the finished products.

[0004] Furthermore, after the glue gun is used, some residue will inevitably remain at the glue outlet. This residual glue can easily drip onto the upper part of the processing platform, making it difficult to clean and thus affecting the normal use of the device. Utility Model Content

[0031] Please see Figure 1-6 A precision hot melt adhesive extrusion machine includes a base 1, with supports 2 on both sides of the upper end of the base 1. A top plate 3 is fixedly mounted on the upper end of the supports 2, and a mounting hole 4 is opened in the middle of the top plate 3. A storage component is movably disposed inside the mounting hole 4. The storage component includes an adhesive storage tank 5, and a heat exchange shell 6 is fixedly mounted on the outer wall of the adhesive storage tank 5. The heat exchange shell 6 contacts the inner wall of the mounting hole 4, and a heating wire 7 is disposed inside the heat exchange shell 6. A motor 8 is fixedly mounted on the upper end of the adhesive storage tank 5, and a heating wire 7 is disposed on one side of the motor 8. A first stirring shaft 9 is rotatably mounted on the upper end of the glue storage tank 5. Both the first stirring shaft 9 and the output end of the motor 8 are equipped with gears 10, which are meshed together. A second stirring shaft 11 is mounted on the output end of the motor 8. Blades 12 are mounted on the outer walls of both the first stirring shaft 9 and the second stirring shaft 11. A hose 13 is mounted on the lower end of the glue storage tank 5. A pump head 14 is mounted on the hose 13. A glue gun 15 is mounted on the other end of the hose 13. A flow detector is mounted above the glue gun 15. A processing table 27 is fixedly mounted on the upper surface of the base 1.

[0032] In this embodiment, a placement rack 16 is fixedly provided on the inner wall of the bracket 2 and on one side. The glue gun 15 and the hose 13 are both movably installed inside the placement rack 16. A limiting groove 17 is opened on the upper end face of the placement rack 16. A limiting ring 18 is fixedly provided on the outer wall of the hose 13. The limiting ring 18 is located inside the limiting groove 17. A pin 19 is slidably provided on the outer wall of the placement rack 16. A slot 20 is correspondingly opened on the outer wall of the limiting ring 18. One end of the pin 19 is located inside the slot 20. A pull block 21 is fixedly provided on the other end of the pin 19. A connecting spring 22 is fixedly provided between the pull block 21 and the placement rack 16.

[0033] More specifically, the user can heat the glue storage tank 5 using the heating wire 7 to prevent the glue from carbonizing. The user can also control the motor 8 to slowly rotate the first stirring shaft 9 and the second stirring shaft 11 via the gear 10, causing the blades 12 to agitate the glue and prevent carbonization and stratification, facilitating precise dispensing. During use, the glue gun 15 can be picked up, aimed at the product, and the pump head 14 opened to allow the glue to flow through the hose 13. The flow detector will then detect the flow rate, facilitating quantitative dispensing. After use, the glue gun 15 and hose 13 can be placed in the storage rack 16, and the limiting ring 18 can be lowered into the limiting groove 17. Then, pulling the pin 19 will insert one end into the slot 20, storing and securing the glue gun 15 for easy retrieval and use. Furthermore, the glue gun 15 is located at the top of the housing 23, preventing residual glue from dripping onto the processing table 27, reducing unnecessary cleaning steps and increasing practicality.

[0034] Please see Figure 1 , Figure 4 and Figure 6 As an embodiment for collecting glue: a box 23 is fixedly provided on the upper end of the base 1. The box 23 is located directly below the glue gun 15. An opening is provided at the front end of the box 23. A collection box 24 is movably provided inside the box 23. Slider 25 is fixedly provided on both sides of the collection box 24. A corresponding groove 26 is provided on the inner wall of the box 23. The slider 25 and the groove 26 are slidably installed.

[0035] Specifically, the user can slide the collection box 24 out of the box body 23 through the cooperation of the slider 25 and the slide 26, so as to facilitate the collection of glue inside for subsequent recycling.

[0036] Please refer to Figure 1 As a further embodiment of the installation of the glue storage tank 5: an installation plate 28 is fixedly provided on the outer wall of the glue storage tank 5, and the installation plate 28 is fixedly installed with the top plate 3 by bolts. A feeding pipe 29 is fixedly provided on the outer wall of the glue storage tank 5 at the upper end.

[0037] Specifically, users can use bolts to disassemble and assemble the mounting plate 28 and the glue storage tank 5 for easy cleaning later.

[0038] In summary, when using the overall equipment: the user can heat the glue storage tank 5 using the heating wire 7 to prevent the glue from carbonizing; the user can also control the motor 8 to drive the gear 10 to slowly rotate the first stirring shaft 9 and the second stirring shaft 11, so that the blades 12 can agitate the glue, preventing carbonization and stratification, and facilitating accurate dispensing. During use, the user can pick up the glue gun 15, aim it at the product, and turn on the pump head 14 to allow the glue to flow through the hose 13. The flow detector will then detect the flow rate, facilitating quantitative glue dispensing (the flow detector is an existing structure and will not be elaborated upon here). After use, the glue gun 15 and hose 13 can be placed in the storage rack 16, and the limiting ring 18 can be lowered into the limiting groove 17. Then, by pulling the pin 19, one end of it can be inserted into the slot 20 to store and fix the glue gun 15, making it easy to retrieve and use later. Since the glue gun 15 is located at the top of the box 23, the residual glue in the glue gun 15 will fall into the collection box 24. Later, the collection box 24 can be slid out from the inside of the box 23 by the cooperation of the slider 25 and the slide 26, so as to facilitate the collection of glue inside for subsequent recycling.

[0039] The motors mentioned above are all controlled by controllers or drivers.
