Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to a dispensing machine. Background Technology

[0002] Dispensing machines are primarily used for the precise application, dispensing, coating, or dripping of adhesives, paints, and other liquids onto specific locations on each product during manufacturing processes. They can be used to apply dots, lines, circles, or arcs. A dispensing machine includes a glue extraction and supply assembly. When the assembly is extracting glue, its outlet is closed; when it is supplying glue, its inlet is closed, resulting in dispensing interruptions. If the assembly simultaneously draws glue from the storage assembly and supplies glue to the dispensing machine, unstable glue storage will occur. Utility Model Content

[0003] The purpose of this invention is to provide a dispensing machine that can dispense glue continuously and stably.

[0004] To achieve the above objectives, this utility model proposes a dispensing machine, including a glue storage assembly, a glue extraction and supply assembly, and a control assembly.

[0005] Adhesive storage assembly, the adhesive storage assembly being used to store adhesive,

[0006] The adhesive supply assembly includes at least two components, each comprising an inlet and an outlet. Valves are provided at both the inlet and outlet. A plunger pump is installed at the inlet, connected to an adhesive storage assembly to draw adhesive from the storage assembly.

[0007] The control component is capable of controlling the opening and closing of the valve at the glue inlet and the valve at the glue outlet, so that at most one of the glue inlet and the glue outlet of the glue pumping and supplying assembly operates at any given time, and the glue outlets of at least two glue pumping and supplying assemblies merge into one glue supply port. The control component is also used to control multiple glue pumping and supplying assemblies to dispense glue alternately.

[0008] Preferably, each glue extraction assembly is equipped with an independent glue storage assembly, or all glue extraction assemblies draw glue from a common glue storage assembly.

[0009] Preferably, there are two glue storage components and two glue extraction components. Each glue storage component and its corresponding glue extraction component constitute a group. The two groups of glue storage components and glue extraction components are arranged horizontally in a mirror arrangement. The dispensing machine also has a housing, and both groups of glue storage components and glue extraction components are located inside the housing.

[0010] Preferably, the housing has pulleys on its bottom surface in the horizontal direction.

[0011] Preferably, the glue storage assembly includes a glue storage tank with its opening facing upward in the vertical direction and a pressure plate pump adapted to the shape of the opening of the glue storage tank. The pressure plate pump is used to compress downward in the vertical direction to force the glue in the glue storage tank out and enter the glue supply assembly through the pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] The dispensing machine of this invention includes a glue extraction and supply assembly, a glue storage assembly, and a control assembly. Valves are installed at both the glue outlet and the glue inlet of the glue extraction and supply assembly. The control assembly controls the opening and closing of the valve at the glue inlet and the valve at the glue outlet. At most, only one of the glue inlet or the glue outlet of the glue extraction and supply assembly is operational at any given time. At least two glue extraction and supply assemblies have their respective glue outlets merged into one glue supply outlet. The control assembly also controls the alternating glue dispensing of multiple glue extraction and supply assemblies. Because the dispensing machine of this invention uses multiple glue extraction and supply assemblies to dispense glue alternately, continuous glue dispensing can be achieved. Furthermore, each glue extraction and supply assembly maintains at most one of its glue inlet and glue outlet operating at any given time, ensuring dispensing stability and greatly improving work efficiency and dispensing quality.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] See Figure 1-4As shown in the figure, a preferred embodiment of the present invention proposes a dispensing machine, including a glue storage component 2, a glue extraction and supply component 1, and a control component (the control component is an existing device; any control component from common electrical control technology can be used, as long as it can enable the coordinated operation of the various components of the dispensing machine; it is not shown in the figure). The glue storage component 2 and the glue extraction and supply component 1 are connected by a pipe (the pipe is not shown in the figure). The control component controls the glue dispensing from the glue storage component 2 and the glue extraction and supply component 1 to extract glue. The glue dispensing from the glue storage component 2, in conjunction with the glue extraction and supply component 1, transfers the glue in the glue storage component 2 to the glue extraction and supply component 1 through the pipe. When the glue extraction and supply component 1 is full of glue, it stops extracting glue from the glue storage component 2 and starts supplying glue to the dispensing machine. The control component controls multiple glue extraction and supply components 1 to alternately extract and supply glue to achieve continuous glue dispensing from the dispensing machine.

[0021] In this embodiment, the glue storage assembly 2 and the glue extraction assembly 1 are housed inside the dispensing machine's housing 4, making the dispensing machine cleaner. Two glue storage assemblies 2 and two glue extraction assemblies 1 are provided, with one glue storage assembly 2 and its corresponding glue extraction assembly 3 forming a group. The two groups of glue storage assemblies 2 and glue extraction assemblies 1 are arranged horizontally in a mirror-like configuration, facilitating glue replenishment to the glue storage assembly 2 and the maintenance and replacement of each component. Each glue extraction assembly is equipped with an independent glue storage assembly; alternatively, in other embodiments, all glue extraction assemblies draw glue from a common glue storage assembly.

[0022] To achieve continuous glue dispensing from the dispensing machine, the glue extraction and supply assembly 1 includes an inlet 13 and an outlet 12. Valves are installed at both the inlet 13 and outlet 12. A plunger pump 11 is installed at the inlet 13, connected to a glue storage assembly 2 to extract glue from it. A control assembly controls the opening and closing of the valves at the inlet 13 and outlet 12, ensuring that at most one of the inlet 13 or outlet 12 operates at any given time. The outlets 12 of two separate glue extraction and supply assemblies merge into one dispensing port (not shown in the figure). The control assembly also controls the alternating dispensing of multiple glue extraction and supply assemblies 1. Because the dispensing machine uses multiple glue extraction and supply assemblies to dispense glue alternately, continuous dispensing is achieved. Furthermore, each glue extraction and supply assembly 1 ensures that at most one of its inlet 13 or outlet 12 is operational, guaranteeing dispensing stability and significantly improving work efficiency and dispensing quality.

[0023] In this embodiment, the glue storage assembly 2 includes a glue storage tank 22 with its opening facing upwards in the vertical direction and a pressure plate pump 21 adapted to the shape of the opening of the glue storage tank 22. The pressure plate pump 21 is used to squeeze downwards in the vertical direction, forcing the glue in the glue storage tank 22 out and into the glue extraction and supply assembly 1 through a pipe. The glue extraction and supply assembly 1 includes a plunger pump 11. Since the pressure plate pump 21 in the glue storage assembly 2 cannot control the amount of glue squeezed out very well, a motor 14 is provided on the plunger pump 11. The motor 14 connected to the plunger pump 11 is a servo motor. In other embodiments, other types of motors can also be used, as long as the plunger pump 11 can extract and supply glue. The glue inlet 13 is connected to the glue storage tank 22. A valve is provided between the glue inlet 13 and the glue storage tank 22. The opening / closing of the valve and the operation of the motor 14 are controlled by the control assembly to achieve precise glue extraction by the plunger pump 11. Of course, in this embodiment, the glue storage component 2 uses a glue storage tank 22 in conjunction with a pressure plate pump 21 to supply glue to the plunger pump 11. In other embodiments, a sealed glue storage tank can also be used to supply glue to the glue supply component 1 by drawing glue, or to supply glue by injecting positive pressure air into the glue storage tank. The appropriate glue storage component 2 can be selected according to the texture of the glue and the glue supply method.

[0024] When the left plunger pump 11 is in the glue-drawing state, the valve connected to the glue inlet 13 of the left plunger pump 11 opens, and the pressure plate pump 21 in the glue storage assembly 2 connected to the left plunger pump 11 squeezes downwards. At the same time, the valve connected to the glue outlet 12 of the left plunger pump 11 closes. The pressure plate pump 21, in conjunction with the motor 14, transfers the glue in the glue storage tank 22 to the plunger pump 11. When the left plunger pump 11 is in the glue-drawing state, the right plunger pump 11 is in the glue-supplying state. The valve connected to the glue inlet 13 of the right plunger pump 11 closes, and the valve connected to the glue outlet 12 opens to supply glue to the dispensing machine. Since the glue outlets 12 of the two plunger pumps 11 are connected in parallel, the control assembly controls the left and right plunger pumps 11 to alternately draw and supply glue to achieve stable and continuous glue dispensing from the dispensing machine.

[0025] To enable the pressure plate pump 21 to rise and fall vertically, the glue storage assembly 2 also includes lifting devices 23 on both sides of the pressure plate pump 21. The pressure plate pump 21 and the lifting devices 23 are connected by a bracket 24 for raising and lowering the pressure plate pump 21, facilitating the loading and unloading of the glue storage tank 22. Meanwhile, the dispensing machine housing 4 is also equipped with pulleys 5 on its bottom surface in the horizontal direction, facilitating the movement of the dispensing machine to better adapt to different usage scenarios.

[0026] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
