Detailed Implementation

[0043] The present invention will now be further described with reference to the accompanying drawings. This description is only for explaining specific embodiments of the present invention and should not be construed as limiting the present invention in any way. Specific embodiments are as follows:

[0044] Example 1

[0045] like Figures 1 to 3 As shown, a mixing and dispensing device includes a main body 10, a movable core 200, a first dispensing channel 70, a second dispensing channel 80, and a dispensing material outlet channel 90. The main body 10 includes a receiving cavity into which the movable core 200 is detachably inserted. Specifically, the movable core 200 includes a first movable core 20 and a second movable core 30 capable of being inserted into the receiving cavity of the mixing and dispensing device. A mixing collision chamber 80 through which the dispensing material can pass is located between the first movable core 20 and the second movable core 30. The inlet end of the mixing collision chamber 80 communicates with the first dispensing channel 40 and the second dispensing channel 50, and the outlet end of the mixing collision chamber 80 communicates with the dispensing material outlet channel 90.

[0046] A first mixing channel 60 is formed between the first movable core 20 and the inner wall of the receiving cavity. The inlet end of the first mixing channel 60 is connected to the first glue inlet channel 40. The outlet end of the first mixing channel 60 is connected to the mixing collision cavity 80. A second mixing channel 70 is formed between the second movable core 30 and the inner wall of the receiving cavity. The inlet end of the second mixing channel 70 is connected to the second glue inlet channel 50, and its outlet end is connected to the mixing collision cavity 80. The mixing end faces of the first movable core 20 and the second movable core 30 are arranged parallel to each other, and the mixing collision cavity 80 is formed between the mixing end faces of the first movable core 20 and the second movable core 30.

[0047] Specifically, the movable core 200 is a cylindrical structure with a notch, including a fixing part 202, a mixing part 201, and a guide surface 203 disposed along its length on the mixing part 201. The guide surface 203 is achieved by subtractive machining on the outer surface of the rod-shaped movable core 200. This machining method is relatively easy to implement in the equipment manufacturing field and can be achieved through various conventional machining methods such as planing, milling, and grinding, as well as various machining methods such as electrical discharge machining and electrochemical machining. In addition, by machining the guide surface 203 on the outer surface of the rod-shaped movable core 200, different sizes of guide surfaces 203 can be machined according to requirements such as rubber flow rate, rubber flow rate, and rubber pressure, which can effectively control the machining size and machining accuracy, and the machining accuracy can reach the micron level. Furthermore, depending on the requirements of rubber flow rate, rubber flow rate, and rubber pressure, movable cores 200 with different sizes of guide surfaces 203 can be replaced.

[0048] The flow guiding surface 203 includes a first flow guiding surface 110 disposed on the first movable core 20 and a second flow guiding surface 120 disposed on the second movable core 30. A first mixing channel 60 is formed between the first flow guiding surface 110 and the inner wall of the receiving cavity, and a second mixing channel 70 is formed between the second flow guiding surface 120 and the inner wall of the receiving cavity.

[0049] One end of the first movable core 20 is inserted into the receiving cavity within the main body 10, and the other end is fixedly connected to the main body 10 via a threaded connection. This threaded connection allows adjustment of the position of the first movable core 20 relative to the main body 10, thereby adjusting the size of the mixing and collision cavity 80 formed between the first movable core 20 and the second movable core 30. This adjustment regulates the flow rate, volume, and pressure of the adhesive material within the mixing and collision cavity 80, thus regulating the mixing and collision effect of the adhesive material. Alternatively, the first movable core 20 can be connected to the nut of a ball screw, allowing for position adjustment via a stepper motor controlling the ball screw. Other drive methods, such as hydraulic cylinders, pneumatic cylinders, or electric push rods, can also be used to adjust the position of the first movable core 20, thereby adjusting the size of the mixing and collision cavity 80. Furthermore, removing the connection between the first movable core 20 and the main body 10 allows for separation of the first movable core 20 from the main body 10. In this case, the receiving cavity within the main body 10 has ample space and no dead corners, enabling the cleaning of residual adhesive material. The second movable core 30 also adopts the same structural form as the first movable core 20 and the main body 10 for position adjustment, which will not be described in detail here.

[0050] The A-component adhesive entering through the first adhesive inlet channel 40, under a certain flow rate and pressure, can first impact the end face of the second movable core 30 and have an atomization effect, and then bounce back and impact the end face of the first movable core 20, thereby achieving reciprocating motion in the mixing collision chamber 80. At the same time, the B-component adhesive entering through the second adhesive inlet channel 50 also enters the mixing collision chamber 80 under a certain flow rate and pressure and performs reciprocating motion, thereby achieving more thorough mixing of the A-component adhesive and the B-component adhesive under the same temperature and pressure.

[0051] Furthermore, by adjusting the positions of the first movable core 20 and the second movable core 30, the size of the mixing and collision chamber 80 can be adjusted, thereby controlling the flow rate and collision of the adhesive material and adjusting the mixing effect of the adhesive material.

[0052] A mixing and dispensing apparatus further includes a sealing device 100 for sealing the movable core 200 and the inner wall of the receiving cavity, effectively preventing the adhesive from flowing out between the outer wall of the movable core 200 and the inner wall of the receiving cavity. The sealing device 100 is preferably a sealing ring, fixed to the outer circumference of the fixing portion 202 of the movable core 200. Alternatively, the sealing device 100 may also employ a labyrinth seal, packing ring, or other sealing methods.

[0053] like Figure 4 As shown, the present invention also discloses a dispensing machine, comprising a feeding module, a heating module 7, a mixing and dispensing device 13, a cooling module, and a dispensing module connected in sequence by pipes. The dispensing machine is configured such that the adhesive is stored in the feeding module, heated by the heating module 7, cooled by the mixing and dispensing device 13, and then discharged through the dispensing module. This dispensing machine is particularly suitable for the field of A / B two-component polyurethane adhesive mixing and dispensing.

[0054] The feeding module is used for supplying adhesive material and includes an adhesive storage device and a pumping device. The pumping device can pump the adhesive material from the storage device into the corresponding adhesive material channel. Specifically, the feeding module includes a first feeding module with a first adhesive storage device 1 and a first pumping device 3, and a second feeding module with a second adhesive storage device 2 and a second pumping device 4. The first pumping device 3 and the first pumping device 4 are preferably commercially available conventional metering pumps.

[0055] Heating module 7 is used to heat the rubber compound pumped out by the pumping device, raising the temperature of the rubber compound. It includes a first heating module 71 and a second heating module 72. The first heating module 71 is nested in the pipeline between the first pumping device 3 and the mixing and dispensing device 13, and the second heating module 72 is nested in the pipeline between the second pumping device 4 and the mixing and dispensing device 13. Heating is achieved through heat exchange. Practice has shown that after heating by heating module 7, the viscosity of the rubber compound decreases, and the physical state of some rubber compounds changes. A certain mass of rubber compound requires more space, and the rubber compound within a limited space generates micro-pressure. Under micro-pressure, the degree of atomization and collision under the same pressure conditions is greatly improved. The reaction after mixing the rubber compound is more active and collisions are more likely to occur than after simple heating. The degree of mixing is higher, and the reaction is more complete. Heating module 7 can be one or more of a gas heating device, an electric heating device, a hot steam heating device, a hot air heating device, or a hot water heating device. A first valve 5 is located between the first pumping device 3 and the first heating module 71 to control the flow of the rubber compound. A second valve 6 for controlling the flow of adhesive material is located between the second pumping device 4 and the second heating module 72.

[0056] The cooling module includes a rubber cooling device 8 for cooling the heated rubber compound. The rubber cooling device 8 is nested in the pipe between the heating module 7 and the dispensing module, cooling the rubber compound through heat exchange. The rubber cooling device 8 can be an air cooling device or a water cooling device. The rubber cooling device 8 can cool the heated rubber compound, preventing the risk of aging caused by heating and ensuring the stability of the mixed rubber compound's quality. Furthermore, the cooling effect of the rubber cooling device 8 effectively reduces the heat generated during rubber compound mixing and reactions, further preventing aging and ensuring the stability of the mixed rubber compound's quality. Preferably, by controlling the flow rate of the cooling medium in the air cooling device or water cooling device, the temperature of the rubber compound is controlled within the range of 10-40 degrees Celsius. Within this temperature range, the rubber compound has sufficient fluidity for dispensing, preventing blockage of the rubber compound pipes. Especially when the temperature of the rubber compound is controlled within the range of 10-20 degrees Celsius, the rubber compound will not age, and the fluidity is closer to the requirements of actual operating conditions, resulting in better performance.

[0057] The dispensing module includes a dispensing head 9 with a dispensing hole. The dispensing head 9 is connected to the outlet end of the adhesive cooling device 8 via a hose. The dispensing head 9 is capable of dispensing adhesive to the product 11 to be dispensed on the worktable 12.

[0058] When a dispensing machine dispenses adhesives, especially polyurethane adhesives, the temperature of the adhesive is controlled within the range of 45-50 degrees Celsius via the heating module 7. Within this temperature range, the adhesive has sufficient reactivity and good collision effect, allowing the mixed adhesive to react fully, improving the quality of the adhesive injected into the product 11 by the dispensing head 9, and enhancing the adhesive stability of the product 11 after dispensing. Conversely, if the temperature is below 45-50 degrees Celsius after heating by the heating module 7, the viscosity of the adhesive is poor, and the mixing, atomization, and collision effect cannot meet the requirements.

[0059] Example 2

[0060] Example 2 is the same as Example 1. The only difference is:

[0061] like Figure 5 As shown, a mixing and dispensing device further includes a mixing chamber 130 and a stirring column 140. The inlet end of the mixing chamber 130 is connected to the mixing collision chamber 80 through a rubber material outflow channel 90. The stirring column 140 is disposed inside the mixing chamber 130 and is used to mix the rubber material passing through the mixing chamber 130. The stirring columns 140 are vertically disposed on the inner wall of the mixing chamber 130 and spaced apart along the rubber material flow direction. The included angle between adjacent stirring columns 140 is 90°. The stirring action of the stirring columns 140 can perform secondary mixing of the rubber material, further improving the uniformity of the rubber material mixture.

[0062] Example 3

[0063] Example 3 is the same as Example 2. The only difference is:

[0064] like Figure 6 As shown and referenced Figure 1 The movable core 200 includes a flow guide 204. The flow guide 204 and the movable core 200 form a mixing collision cavity 80, and their end faces and circumferential surfaces are all connected. The flow guide surface 203 is the bottom surface of the flow guide 204. The flow guide 204 can further reduce the size of the first mixing channel 60 or the second mixing channel 70, ensuring compliance with the requirements of low flow rate or low flow volume of the adhesive. Moreover, the flow guide 204 does not significantly increase its processing difficulty, ensuring processing dimensions and processing accuracy.

[0065] Example 4

[0066] Example 4 is the same as Example 2. The only difference is:

[0067] like Figure 7 As shown and referenced Figure 1 The movable core 200 is a regular hexagonal structure with the same cross-sectional dimensions. The movable core 200 includes a fixing part 202, a mixing part 201, and a guide surface 203 disposed in the mixing part 201 along its length direction. This structure can limit the movable core 200 by relying on the straight edge along the length direction to prevent it from deflecting. It also prevents the first mixing channel 60 and the second mixing channel 70 from having too small an interface due to deflection, which could lead to insufficient colloid flow or blockage.

[0068] Furthermore, other structures with identical cross-sectional shapes and dimensions along the length direction, and whose cross-sections are regular polygons or have straight lines, are also applicable to this invention.

[0069] Example 5

[0070] Example 5 is the same as Example 2. The only difference is:

[0071] like Figures 8 to 10As shown, the movable core 200 includes a fixing part 202 and a mixing part 201. The mixing part 201 includes a first cylinder 2013, a frustum 2012, and a second cylinder 2011 connected in sequence. The diameter of the upper bottom surface of the frustum 2012 is the same as the diameter of the second cylinder 2011, and the diameter of the lower bottom surface is the same as the diameter of the first cylinder 2013. The receiving cavity 300 includes a first cylindrical cavity 301, a frustum cavity 302, and a second cylindrical cavity 303 connected in sequence. The first cylinder 2013 can be placed into the first cylindrical cavity 301, the frustum 2012 can be placed into the frustum cavity 302, and the second cylinder 2011 can be placed into the second cylindrical cavity 303. There are gaps for adhesive flow between the first cylinder 2013 and the inner wall of the first cylindrical cavity 301, between the frustum 2012 and the frustum cavity 302, and between the second cylinder 2011 and the second cylindrical cavity 303. The first movable core 20 and the second movable core 30 are placed in the receiving cavity 300, and their relative positions to the main body 10 are adjustable. By adjusting the positions of the first movable core 20 and / or the second movable core 30, the gap between the frustum 2012 and the frustum cavity 302 can be controlled, thereby controlling the adhesive flow rate or adhesive volume.

[0072] Therefore, those skilled in the art should recognize that although exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
