Description

Technical Field

[0001] This utility model relates to the field of dry adhesive label technology, and in particular to a dispensing device for self-adhesive labels. Background Technology

[0002] A self-adhesive label dispensing device is an automated machine specifically designed for precisely applying adhesive to self-adhesive label materials. This device uses a mechanical positioning system and an adhesive dosage control system to accurately apply hot melt adhesive, water-based adhesive, or solvent-based adhesive to the back of the label according to a predetermined pattern, giving the label the adhesive properties required for subsequent bonding. However, existing self-adhesive label dispensing devices still have problems such as label displacement during dispensing, the inability to apply adhesive in large areas first and then touch up in small areas, and the potential for dispensing dead zones on irregular labels.

[0003] Therefore, it is essential to invent a dispensing device for self-adhesive labels. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a dispensing device for self-adhesive labels, solving the issues that existing self-adhesive label dispensing devices still suffer from, such as label displacement during dispensing, the inability to apply adhesive on a large scale first and then touch up in a small area, and the potential for dispensing dead zones on irregular labels. The self-adhesive label dispensing device includes a supporting substrate, a three-axis drive structure, a support frame, a dispensing structure, a large-strand glue delivery tube, and a small-strand glue delivery tube. The three-axis drive structure is fixedly mounted on the outer surface of the supporting substrate, and the support frame is mounted on the three-axis drive structure. The dispensing structure is fixedly mounted on the support frame. Both the large-strand glue delivery tube and the small-strand glue delivery tube are fixedly mounted on the top of the dispensing structure.

[0005] The support base includes a workbench, a connecting frame, a placement surface, a negative pressure chamber, and an exhaust pipe. The connecting frame is fixedly installed on the surface of the workbench, and the placement surface is fixedly installed inside the connecting frame. The negative pressure chamber penetrates the workbench and is fixedly installed at the bottom of the connecting frame, while the exhaust pipe is fixedly installed on the outside of the negative pressure chamber.

[0006] The dispensing structure includes a full-area dispensing structure, a large-area dispensing head, an auxiliary dispensing structure, and a filling dispensing head. The full-area dispensing structure is fixedly mounted on a support frame, and the large-area dispensing head is fixedly mounted on the bottom end of the full-area dispensing structure. The auxiliary dispensing structure is fixedly mounted on the support frame, and the filling dispensing head is fixedly mounted on the bottom end of the auxiliary dispensing structure.

[0007] The worktable inside the supporting substrate is made of an aluminum metal plate, and a rectangular window is set in the middle of the worktable. The connecting frame, the placement surface and the negative pressure chamber are connected as one body to form a relatively sealed rectangular box, and are slidably installed inside the rectangular window in the middle of the worktable. Finally, they are fixed by the connection between the connecting frame and the worktable. The surface of the placement surface is provided with several air inlets. The negative pressure chamber can draw air outward through the air extraction pipe to form a negative pressure, and the negative pressure state of the negative pressure chamber can allow air to enter inward through the air inlets of the placement surface. The label that needs to be glued is placed on the surface of the placement surface and is adsorbed onto the surface of the placement surface by the negative pressure of the negative pressure chamber.

[0008] The entire dispensing structure can reciprocate in multiple directions via a three-axis drive structure. The full-scale extrusion structure and large-area dispensing head work first to dispense glue over a large area, while the auxiliary extrusion structure and filling dispensing head work subsequently to dispense glue in narrow spaces.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The support substrate of this utility model enables the formation of a modular negative pressure adsorption system. The negative pressure chamber's suction effect firmly adsorbs the label onto the placement surface, preventing displacement during dispensing. Meanwhile, its rectangular window design allows for adjustment or replacement of the adsorption module, and the stability of the worktable directly ensures the coordinated operation accuracy of the three-axis drive structure and the dispensing structure, achieving efficient and high-precision dispensing operations.

[0011] This invention features a dispensing structure that enables rapid, large-area dispensing through a comprehensive extrusion structure and a large-area dispensing head. Simultaneously, an auxiliary extrusion structure drives a filling dispensing head for precise glue replenishment, forming an intelligent dispensing process that proceeds "from overall to local." Large and small glue delivery tubes independently supply glue to the comprehensive and auxiliary extrusion structures, respectively, achieving precise, graded control of the glue quantity. This structure works collaboratively with a three-axis drive structure and perfectly complements the negative pressure adsorption system of the supporting substrate, ensuring both dispensing efficiency and precision for complex patterns.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] As attached Figure 1 To be continued Figure 3 As shown.

[0019] This utility model provides a dispensing device for self-adhesive labels, comprising a supporting substrate 1, a three-axis drive structure 2, a support frame 3, a dispensing structure 4, a large-strand dispensing tube 5, and a small-strand dispensing tube 6, wherein: the three-axis drive structure 2 is fixedly installed on the outer side of the surface of the supporting substrate 1, and the support frame 3 is installed on the three-axis drive structure 2, and the dispensing structure 4 is fixedly installed on the support frame 3; the large-strand dispensing tube 5 and the small-strand dispensing tube 6 are both fixedly installed on the top of the dispensing structure 4.

[0020] The support base plate 1 includes a workbench surface 11, a connecting frame 12, a placement surface 13, a negative pressure chamber 14, and an exhaust pipe 15. The connecting frame 12 is fixedly installed on the surface of the workbench surface 11, and the placement surface 13 is fixedly installed inside the connecting frame 12. The negative pressure chamber 14 penetrates the workbench surface 11 and is fixedly installed at the bottom of the connecting frame 12, and the exhaust pipe 15 is fixedly installed on the outside of the negative pressure chamber 14.

[0021] The dispensing structure 4 includes a full-area dispensing structure 41, a large-area dispensing head 42, an auxiliary dispensing structure 43, and a filling dispensing head 44. The full-area dispensing structure 41 is fixedly installed on the support frame 3, and the large-area dispensing head 42 is fixedly installed at the bottom end of the full-area dispensing structure 41. The auxiliary dispensing structure 43 is fixedly installed on the support frame 3, and the filling dispensing head 44 is fixedly installed at the bottom end of the auxiliary dispensing structure 43.

[0022] The workbench 11 inside the support base plate 1 is made of an aluminum metal plate, and a rectangular window is provided in the middle of the workbench 11; the connecting frame 12, the placement surface 13 and the negative pressure chamber 14 are connected as a whole to form a relatively sealed rectangular box, and are slidably installed inside the rectangular window in the middle of the workbench 11, and finally fixed by the connection between the connecting frame 12 and the workbench 11; the surface of the placement surface 13 is provided with several air inlets; the negative pressure chamber 14 can draw air out through the air extraction pipe 15 to form a negative pressure, and the negative pressure state of the negative pressure chamber 14 can allow air to enter through the air inlets of the placement surface 13. The surface of the placement surface 13 is on which a label that needs to be glued is placed, and it is adsorbed onto the surface of the placement surface 13 by the negative pressure of the negative pressure chamber 14.

[0023] The dispensing structure 4 can move back and forth in multiple directions via the three-axis drive structure 2. The full-area dispensing structure 41 and the large-area dispensing head 42 work first to dispense glue over a large area. The auxiliary dispensing structure 43 and the filling dispensing head 44 then work to dispense glue in a narrow area.

[0024] The working principle of this self-adhesive label dispensing device is as follows:

[0025] First, the operator places the label to be glued flat on the placement surface 13 of the support substrate 1. After starting the equipment, the air extraction pipe 15 starts working, creating a negative pressure environment in the negative pressure chamber 14. The label is firmly adsorbed and fixed through the air inlets distributed on the placement surface 13, preventing it from shifting during the glue dispensing process.

[0026] Next, the three-axis drive structure 2 begins to operate, driving the support frame 3 and the dispensing structure 4 mounted on it to move in three-dimensional space. The large glue delivery tube 5 delivers glue to the full-coverage extrusion structure 41, and performs a rapid, large-area initial glue dispensing operation on the label through the large-area dispensing head 42.

[0027] After completing large-area dispensing, the equipment automatically switches to fine dispensing mode. A small glue delivery tube (6) supplies glue to the auxiliary extrusion structure (43), precisely filling hard-to-cover areas such as label corners and small patterns with glue through the filling dispensing head (44). The entire process is precisely controlled by the three-axis drive structure (2), ensuring accurate dispensing positioning.

[0028] This device achieves efficient and high-precision automated dispensing production of self-adhesive labels through the stable support of the support substrate 1, the reliable fixation of the negative pressure adsorption system, the precise positioning of the three-axis drive structure 2, and the dual-mode collaborative operation of the dispensing structure 4. The division of labor and cooperation between the full-range extrusion structure 41 and the auxiliary extrusion structure 43 ensures both production efficiency and dispensing quality, making it particularly suitable for the production needs of labels with complex patterns.

[0029] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
