Description

Technical Field

[0001] This utility model relates to the field of edge sealing equipment, specifically to a multi-port output nozzle and dispensing system. Background Technology

[0002] In edge banding of boards, the first step is to apply adhesive to the edges of the board. Then, an edge banding roller is used to press the edge banding strip onto the applied adhesive area. The quality of the adhesive application directly affects the final edge banding effect. On one hand, the amount of adhesive affects the banding result; too little adhesive results in poor adhesion, while too much adhesive causes overflow, affecting the board's appearance. On the other hand, the dispensing method of the adhesive head also affects the banding effect. For example, if the dispensing head dispenses too few adhesive dots, the adhesive cannot pre-wet the board, reducing the bonding strength between the adhesive and the board and preventing the achievement of the best edge banding effect.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Figure 1 This is a three-dimensional structural diagram of the multi-port output nozzle according to an embodiment of the present invention. Figure 2 This is a schematic cross-sectional view of the composite unit structure according to an embodiment of the present invention.

[0027] This utility model embodiment provides a multi-port output nozzle, including two or more composite units;

[0028] Each of the composite units includes a main body 5, which has a common hole 7 at one end, a first connecting hole 3 at the tail, and a second connecting hole 2 at the tail. The common hole 7, the first connecting hole 3, and the second connecting hole 2 are connected by a flow channel 6 located inside the main body 5. A first mating part 1 and a second mating part 4 are respectively provided on both sides of the main body 5.

[0029] The two or more composite units are arranged side by side and closely attached in sequence;

[0030] In each of the composite units, the direction of the line connecting the end and the tail of the main body 5 is the axial direction of the main body 5, and the axes of the main bodies 5 of all the composite units are parallel to each other.

[0031] In two adjacent composite units, the main body 5 of one composite unit slides into a second mating part 4 corresponding to the main body 5 of the other composite unit based on the corresponding first mating part 1, or the main body 5 of one composite unit slides into a first mating part 1 corresponding to the main body 5 of the other composite unit based on the corresponding second mating part 4, and the relative sliding direction of the sliding fit is parallel to the direction of the axis.

[0032] In practical implementation, the common hole 7 of each composite unit in the multi-port output nozzle of this utility model embodiment can dispense glue. When dispensing glue to the side of the board, the multiple composite units arranged side by side can dispense glue to multiple points on the board, thereby making the glue more evenly distributed on the side of the board. In addition, the glue dispensing of each composite unit is actually controllable. Therefore, this multi-port output nozzle can adapt to the glue dispensing operation of boards of different thicknesses, reducing the tediousness of changing dispensing heads. In addition, each composite unit also has a first connecting hole 3 and a second connecting hole 2 located at the tail. The first connecting hole 3 is used for glue input, and the second connecting hole 2 can be used for gas extraction. When there is actual need, the composite units located on both sides can stop glue delivery and switch the function to gas extraction, thereby absorbing the glue overflowing on the surface of the board and improving the edge sealing quality of the board.

[0033] In an optional embodiment, the radial cross-sectional shape of the flow channel 6 inside the main body 5 is circular.

[0034] In an optional implementation, the axial cross-sectional shape of the flow channel 6 inside the main body 5 is U-shaped.

[0035] In an optional embodiment, the first mating part 1 is located on the columnar structure at the outer edge of the main body 5;

[0036] The second mating part 4 is a groove structure that complements the columnar structure;

[0037] In two adjacent composite units, the columnar structure and the groove structure cooperate to limit the movement, and the two corresponding composite units only have relative sliding degrees of freedom along the axial direction.

[0038] In an optional embodiment, the radial cross-sectional shape of the columnar structure is trapezoidal, the top side of the trapezoid is shorter than the bottom side, and the top side is located on one side of the main body 5.

[0039] In this embodiment of the utility model, the first mating part 1 and the second mating part 4 each have a set of protruding structures and groove structures.

[0040] Figure 3This is a structural block diagram of a dispensing system according to an embodiment of the present invention. Furthermore, this embodiment also provides a dispensing system including a controller, an air suction assembly, a glue delivery assembly, and the aforementioned multi-port output nozzle. Specifically, in the illustrated structure, an example is given where the multi-port output nozzle has three composite units.

[0041] The air intake assembly includes the same number of air intake units as the composite unit. Each air intake unit includes an air intake power element 11 and an air intake pipe. One end of the air intake pipe is connected to the air intake power element 11, and the other end of the air intake pipe is connected to the first connection hole 3 in the corresponding composite unit. The control end of the air intake power element 11 is connected to the controller.

[0042] The glue delivery assembly includes the same number of glue delivery units as the composite units. Each suction unit includes a glue supply element 10 and a glue delivery pipe. One end of the glue delivery pipe is connected to the glue supply element 10, and the other end of the glue delivery pipe is connected to the second connection hole 2 in the corresponding composite unit. The control terminal of the glue supply element 10 is connected to the controller. Figure 3 The dashed lines in the diagram are used to represent the control relationship between the controller and the glue supply element, as well as the control relationship between the controller and the suction power element.

[0043] Accordingly, in the dispensing system of this utility model embodiment, each composite unit has two functions based on the corresponding air suction component and glue delivery component. One function is to deliver glue to the common hole 7 through the second connecting hole 2, and the other function is to suction air from the common hole 7 through the first connecting hole 3. The air suction function can be used to remove glue that overflows onto the edge surface of the board and keep the board surface clean.

[0044] Specifically, the suction power element 11 is a vacuum pump.

[0045] Specifically, the adhesive supply element 10 is a peristaltic pump.

[0046] Furthermore, to avoid the simultaneous operation of the suction power element 11 and the glue supply element 10, the suction power element 11 and the glue supply element 10 corresponding to each composite unit operate in opposite states. This operating state can be controlled by a physical structure, such as by setting a single-pole three-throw switch; or by writing the corresponding logic program into the controller.

[0047] In summary, this utility model embodiment provides a multi-port output nozzle and dispensing system. Unlike single-point dispensing, this multi-port output nozzle uses multiple composite units, each of which has dispensing capability, enabling multi-point dispensing. Furthermore, the multiple composite units can be adjusted according to the thickness of the board material to meet the dispensing requirements of boards of different thicknesses, providing excellent ease of use and effectively improving the edge sealing effect of the board material.
