Description

Technical Field

[0001] This utility model relates to the field of automated dispensing technology, specifically a colloid pressurization mixing device for dispensing. Background Technology

[0002] An automated dispensing device is an industrial automation equipment used for dispensing adhesive during the production process. It is typically computer-controlled, allowing for programmable control of parameters such as dispensing position, size, and speed. The working principle of automated dispensing equipment mainly involves pressure control and motion control, using stepper motors or servo motors to control the movement trajectory of the dispensing needle, achieving precise adhesive dot release.

[0003] In modern production, pressurized mixing and dispensing guns are commonly used for dispensing. These guns rely on pressure control and fluid dynamics principles to mix and dispense the adhesives. Specifically, during dispensing, the pressure in the A and B adhesive containers is controlled by adjusting the pressure regulating valve, forcing the adhesive into the mixing chamber. The mixing system within the chamber then mixes the two or more adhesives, such as through static mixing via a specially designed mixing tube, utilizing the splitting and merging processes that occur as the adhesive flows within the tube.

[0004] During the above mixing process, the residence time of the colloid in the mixing chamber is relatively short. In this short time, it is difficult to ensure that two or more colloids can be fully mixed by processes such as splitting and merging. This will lead to unstable viscosity of the adhesive, thus affecting the subsequent dispensing quality. Utility Model Content

[0005] The purpose of this invention is to provide a colloid pressurization mixing device for dispensing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A colloid pressurization mixing device for dispensing, comprising:

[0008] A glue dispensing gun, wherein the glue dispensing gun is connected to a first storage tank and a second storage tank disposed outside the glue dispensing gun via a first feed gun and a second feed gun;

[0009] The dispensing gun includes an upper barrel and a lower barrel. A mixing component is rotatably disposed inside the upper barrel. During the process of the first feed gun and the second feed gun injecting glue into the upper barrel, the mixing component can be driven to rotate relative to the upper barrel so as to mix the glue entering the upper barrel.

[0010] The mixing component is also equipped with a stirring structure, which can stir the two colloids during the rotation of the mixing component.

[0011] A sealing structure is provided inside the lower gun barrel. The sealing structure cooperates with the mixing component. After a certain period of glue injection, the sealing structure can connect the upper gun barrel and the lower gun barrel.

[0012] The dispensing colloid pressurized mixing device as described above: the mixing component includes a rotating cylinder rotatably mounted inside the upper gun barrel, and the rotating cylinder is provided with multiple sets of mixing chambers at equal intervals along the circumferential direction.

[0013] The colloid pressurized mixing device for dispensing described above: each of the mixing chambers is provided with a stirring structure, the stirring structure includes a stirring component and a driving component, the stirring component includes an impeller rotatably installed in the mixing chamber, multiple sets of impellers are equidistantly arranged in the longitudinal direction, and a bevel gear is coaxially fixed on the rotating shaft of each set of impellers.

[0014] The colloid pressurized mixing device for dispensing as described above: the driving component includes a bevel gear ring fixedly disposed inside the upper gun barrel, the bevel gear ring meshing with the bevel gear.

[0015] The above-mentioned dispensing colloid pressurized mixing device: the sealing structure includes a sealing element and a trigger element. The sealing structure includes a sealing ring rotatably installed in the lower gun barrel. The sealing ring has multiple sets of discharge ports equidistantly opened on it, and the inner wall of the sealing ring is provided with a toothed structure along its circumference.

[0016] The dispensing colloid pressurization mixing device described above: the triggering element includes a main gear fixedly arranged coaxially with the rotating cylinder, the main gear is coaxial with the sealing ring, and a driven gear is arranged between the sealing ring and the main gear. Multiple sets of driven gears are arranged equidistantly around the circumference of the sealing ring, and each set of driven gears meshes with the main gear and the tooth structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By setting up a rotating drum, the tangentially fed colloid drives the rotating drum to rotate, so that the two colloids are alternately and repeatedly filled into the same mixing chamber on the rotating drum in a layered manner. During the rotation of the rotating drum, the colloids in the mixing chamber can be stirred simultaneously by the stirring structure, thereby achieving double mixing of the colloids and improving the mixing uniformity between the two colloids. This results in a more stable quality and higher viscosity of the colloid after mixing.

[0019] At the same time, by setting up a sealing structure and utilizing the cooperation between the triggering structures, the upper and lower gun barrels are automatically connected when the injection stops, so that the mixed colloidal material is discharged into the lower gun barrel for subsequent dispensing.

[0026] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0027] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0028] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0029] Please see Figures 1-5In this embodiment of the present invention, a colloid pressurized mixing device for dispensing includes: a dispensing gun 1, wherein the dispensing gun 1 is connected to a first storage tank 2 and a second storage tank 3 disposed outside the dispensing gun 1 through a first feeding gun 5 and a second feeding gun 4.

[0030] In particular, please see Figure 2 , Figure 3 Both the first feed gun 5 and the second feed gun 4 are inserted into the dispensing gun 1 in a tangential direction. Before dispensing, the first feed gun 5 and the second feed gun 4 are instructed by the control system to draw the adhesive in the first storage tank 2 and the second storage tank 3 into the dispensing gun 1 for mixing, so as to prepare for subsequent dispensing operations.

[0031] For details, please refer to Figure 2 , Figure 3 The dispensing gun 1 includes an upper barrel 101 and a lower barrel 102. A mixing component is rotatably disposed inside the upper barrel 101. During the process of the first feed gun 5 and the second feed gun 4 injecting glue into the upper barrel 101, the mixing component can be driven to rotate relative to the upper barrel 101 so as to mix the glue entering the upper barrel 101.

[0032] The mixing component includes a rotating cylinder 6 rotatably installed inside the upper barrel 101, and the rotating cylinder 6 is provided with multiple sets of mixing chambers 601 at equal intervals along the circumferential direction;

[0033] In particular, please see Figure 3 , Figure 4 , Figure 5 The above-mentioned mixing chamber 601 is provided in seven sets. The cross-section of each set of mixing chamber 601 is U-shaped. When the first feeding gun 5 and the second feeding gun 4 inject the colloid into the upper gun barrel 101, the colloid enters the upper gun barrel 101 quickly in a tangential direction. At this time, the impact of the colloid on the rotating cylinder 6 can drive the rotating cylinder 6 to rotate. During this process, each set of mixing chambers 601 passes by the inlet of the first feeding gun 5 and the second feeding gun 4 in turn, so that during the rotation of the rotating cylinder 6, both colloids can enter the same mixing chamber 601 once. After rotating multiple times, it is equivalent to adding the two colloids in layers, which helps to make the two colloids mix more evenly.

[0034] Furthermore, each of the above-mentioned mixing chambers 601 is provided with a discharge port 602 at one end facing the lower gun barrel 102. The discharge port 602 is used to unload the mixed colloid in the mixing chamber 601 for dispensing operation by the lower gun barrel 102.

[0035] Furthermore, please refer to Figure 3 , Figure 4The mixing component is also equipped with a stirring structure, which can stir the two colloids during the rotation of the mixing component.

[0036] Each mixing chamber 601 is provided with a stirring structure, which includes a stirring component and a driving component. The stirring component includes an impeller 13 rotatably installed in the mixing chamber 601. Multiple sets of impellers 13 are equidistantly arranged in the longitudinal direction. A bevel gear 8 is coaxially fixed on the rotating shaft of each set of impellers 13.

[0037] The driving component includes a bevel ring 9 fixedly disposed inside the upper barrel 101, and the bevel ring 9 meshes with the bevel gear 8;

[0038] In combination with the above, when the first feed gun 5 and the second feed gun 4 inject colloidal raw materials into the upper barrel 101, the rotating cylinder 6 can rotate continuously. During the process, the bevel gear 8 and the bevel gear ring 9 enter a meshing transmission state, which can drive the impeller 13 to rotate.

[0039] Therefore, when the rotating cylinder 6 rotates, the impeller 13 can rotate synchronously, thereby stirring and mixing the two colloids that enter the mixing chamber 601. Due to the orientation of the impeller 13, when the impeller 13 rotates, the rotating blades can stir the colloids in the mixing chamber 601 in the longitudinal direction, so that the mixing between the two colloids is more uniform, thereby improving the viscosity of the mixed colloids when used later.

[0040] Furthermore, please refer to Figure 3 , Figure 5 A sealing structure is provided inside the lower gun barrel 102. The sealing structure cooperates with the mixing component. After a certain period of glue injection, the sealing structure can connect the upper gun barrel 101 and the lower gun barrel 102.

[0041] The sealing structure includes a sealing component and a trigger component. The sealing structure includes a sealing ring 7 rotatably installed in the lower gun barrel 102. Multiple sets of discharge ports 701 are equidistantly provided on the sealing ring 7, and a toothed structure 12 is provided on the inner wall of the sealing ring 7 along its circumference.

[0042] Specifically, please refer to Figure 3 , Figure 5 A partition plate 14 is provided between the rotating cylinder 6 and the sealing ring 7. The partition plate 14 has a through hole 1401 that is compatible with the rotating cylinder 6 and the discharge port 701.

[0043] In the initial state, the feed port 701 and the through hole 1401 are completely misaligned. At this time, the lower gun barrel 102 is in a blocked state, and the colloid in the upper gun barrel 101 will not flow into the lower gun barrel 102.

[0044] Before dispensing, during the mixing of the adhesive in the upper barrel 101, the continuously rotating cylinder 6 can drive the trigger to move, so that after the adhesive has been injected for a certain period of time, the discharge port 701 on the sealing ring 7 coincides with the through hole 1401 and the discharge port 602, thereby connecting the upper barrel 101 and the lower barrel 102, so that the well mixed adhesive material enters the lower barrel 102 for dispensing by the dispensing gun 1.

[0045] Specifically, please refer to Figure 3 , Figure 5 The trigger includes a main gear 11 fixedly coaxially with the rotating cylinder 6. The main gear 11 is coaxial with the sealing ring 7, and a driven gear 10 is provided between the sealing ring 7 and the main gear 11. Multiple sets of driven gears 10 are equidistantly arranged around the circumference of the sealing ring 7, and each set of driven gears 10 meshes with the main gear 11 and the tooth structure 12.

[0046] The main gear 11, the driven gear 10, and the tooth structure 12 cooperate with each other to achieve differential transmission. That is, after the main gear 11 follows the rotating cylinder 6 for several revolutions, it can only drive the sealing ring 7 to rotate at a certain angle.

[0047] In this embodiment, the capacity of the dispensing gun 1 is constant. Therefore, the dispensing time of the first feed gun 5 and the second feed gun 4 is constant, and the number of rotations of the rotating cylinder 6 is also relatively constant. When the first feed gun 5 and the second feed gun 4 stop dispensing, the outlet 602 coincides with the through hole 1401. The sealing ring 7, with the cooperation of the trigger, forces the discharge port 701 to coincide with the through hole 1401. Then, the mixed adhesive material is poured into the lower gun barrel 102 through the outlet 602, the through hole 1401 and the discharge port 701. Until the sensor in the dispensing gun 1 senses that the adhesive in the lower gun barrel 102 has been used up, the control system drives the sealing ring 7 to seal the through hole 1401 and drives the first feed gun 5 and the second feed gun 4 to dispense adhesive into the upper gun barrel 101 again.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
