DETAILED DESCRIPTION

[0040] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 11 The present invention provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, it includes a feeding mechanism 2, which is used for conveying and heating the spraying raw materials;

[0042] A premixing mechanism 3, which is used for expected mixing of spraying raw materials, and a support frame 1 fixedly connected to the outside of the premixing mechanism 3;

[0043] A stirring mechanism 4, which is used for formally stirring the spraying raw material;

[0044] A static mechanism 5, which is used to statically degas the mixed spraying material;

[0045] The feeding mechanism 2 is fixedly mounted on the premixing mechanism 3 , the stirring mechanism 4 is fixedly mounted at the bottom of the premixing mechanism 3 , and the stationary mechanism 5 is fixedly connected to the outer side of the support frame 1 .

[0046] The feeding mechanism 2 includes a feeding pipe 21, which is fixedly connected to the top of the center frame 31 and extends inside the center frame 31. The outer side of the feeding pipe 21 is fixedly connected to a square tube 22, the outer side of the square tube 22 is fixedly connected to an insulating spring 23, the top of the insulating spring 23 is fixedly connected to a sleeve 24, the sleeve 24 is slidably adapted to the outer side of the square tube 22, the inside of the square tube 22 is fixedly connected to a polyurethane foam board 27, the outer side of the polyurethane foam board 27 is fixedly connected to the sleeve 24, the outer side of the sleeve 24 is fixedly connected to a plate-type heating element 28, wherein the plate-type heating element 28 is inside the square tube 22, the top of the sleeve 24 is fixedly connected to a connecting rod 25, and the connecting rod 25 is fixedly connected to the top of the sleeve 24. The top of the rod 25 is fixedly connected with an open mesh 26, and the open mesh 26 is slidably adapted to the bottom of the inner cavity of the feed pipe 21. The outer side of the open mesh 26 is fixedly connected with a leak-proof spring sheet 29, which is a rubber sealing gasket, which mainly plays a role in shielding the slot at the sliding part to prevent the raw material from falling into the slot; the end of the leak-proof spring sheet 29 away from the open mesh 26 is fixedly connected to the inner side of the feed pipe 21, and the spraying raw material is put into the port at the top of the feed pipe 21. At this time, part of the spraying raw material will agglomerate or gather due to problems such as viscosity or low temperature, so the spraying raw material will squeeze the open mesh 26. If the spraying raw material has no viscosity or other problems, it will directly pass through. The open-pored mesh 26 flows downward, wherein the viscous spraying raw material is generally a thickener, and the impacted open-pored mesh 26 moves downward along the bottom of the feed pipe 21, wherein the leak-proof spring sheet 29 fixedly connected to the outer side of the open-pored mesh 26 has elasticity and the function of preventing the spraying raw material from leaking out, and then the connecting rod 25 fixedly connected to the bottom of the open-pored mesh 26 will move downward with the sliding sleeve 24, wherein the heat-insulating spring amplitude 23 fixedly connected to the bottom of the sliding sleeve 24 not only has heat-insulating performance but also has elasticity, and also plays a role in resetting the sliding sleeve 24, and then the plate-type heating element 28 fixedly connected to the outer side of the sliding sleeve 24 will also move downward accordingly, and at the same time At the same time, the polyurethane foam board 27 fixedly connected to the inner end of the sliding sleeve 24 will also move downward, wherein the number of the polyurethane foam boards 27 is several, and the whole formed by the several polyurethane foam boards 27 has a retractable function. Finally, as the sliding sleeve 24 moves downward, the polyurethane foam board 27 will move downward. Therefore, the heat emitted by the plate heating element 28 will float to the bottom of the feed pipe 21 and heat it due to the downward movement of the polyurethane foam board 27. The temperature range is about 40°C. On the one hand, it can avoid melting of the polyurethane foam board 27, and on the other hand, it can achieve the effect of slightly melting the spraying raw materials and preventing agglomeration.

[0047] In addition, the maximum melting range of the spray material (gelatin) is around 45°C, so heating at 40°C will usually melt it but not solidify it.

[0048] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the premixing mechanism 3 includes a central frame 31, a central rod 32 is fixedly connected to the inside of the central frame 31, a double-headed net 33 is fixedly connected to the outside of the central rod 32, a frame plate 34 is fixedly connected to the bottom of the double-headed net 33, and traction plates 35 are symmetrically arranged on both sides of the top of the frame plate 34, and one end of the traction plate 35 away from the frame plate 34 is fixedly connected to the inner side of the central frame 31, and a premixing component 36 is fixedly connected to the bottom of the frame plate 34.

[0049] The premixing assembly 36 includes a hollow platform 361, which is fixedly connected to the bottom of the frame 34. The bottom of the hollow platform 361 is fixedly connected with an outlet pipe 363. The spraying raw materials discharged from the feed pipe 21 will collide with the double-headed net 33. There are two feed mechanisms 2, which are symmetrically arranged on the top of the center frame 31. At the same time, the spraying raw materials input by the two feed mechanisms 2 are different. Therefore, the two different spraying raw materials will collide with the double-headed net 33 in an opposite direction. At this time, part of the spraying raw materials will pass through the holes on the double-headed net 33 and collide with each other, and then enter the hollow platform 361. Finally, the spraying raw materials are discharged downward through the outlet pipe 363. At this time, the two spraying raw materials are preliminarily premixed. Side pipes 362 are symmetrically arranged on both sides of the hollow platform 361. The side pipes 362 are fixedly connected to the bottom of the frame 34. The bottom of the side pipes 362 is fixedly connected with a second mixing assembly 364.

[0050] The second mixing assembly 364 includes a No. 1 support 3641 and a No. 2 support 3643. The No. 1 support 3641 and the No. 2 support 3643 are both fixedly connected to the bottom of the side pipe 362. The No. 1 spiral auger 3642 is fixedly connected to the outer side of the No. 1 support 3641, and the No. 2 spiral auger 3644 is fixedly connected to the outer side of the No. 2 support 3643. The No. 1 spiral auger 3642 and the No. 2 spiral auger 3644 are both fixedly connected to the bottom of the side pipe 362. The first spiral auger 3642 and the second spiral auger 3644 are both connected to the side pipe 362. The inside of the first spiral auger 3642 and the second spiral auger 3644 are both provided with a perforation 3645. The inside of the perforation 3645 is fixedly connected with a partition rod 3646. The remaining spraying material will continue to move downward along the surface of the double-headed net 33 and enter the side pipe 362. The traction plate 35 fixedly connected to the top of the frame plate 34 plays the role of traction of the spraying material sprayed or splashed into the inside of the side pipe 362. Similarly, the side pipe 362 , there are two traction plates 35, so the two types of spray materials will enter the No. 1 spiral auger 3642 and the No. 2 spiral auger 3644 respectively, wherein the No. 1 spiral auger 3642 and the No. 2 spiral auger 3644 are both provided with perforations 3645, and the perforations 3645 on the two are all on the same vertical line, and at the same time, a plurality of partition rods 3646 are fixedly connected to the perforations 3645, so when the spray materials slide downward along the spiral auger, part of the spray materials will pass through the plurality of perforations 3645 in turn and fall vertically downward, while the remaining part of the spray materials will continue to slide downward, and similarly, the spray materials that continue to slide downward will be divided into two parts, one part will fall vertically through the perforations 3645, and the other part will continue to slide downward, so that the spray materials can be premixed in batches eventually. In addition, small batch mixing can make the various components contact and mix more fully, reduce the uneven mixing that may occur due to the large amount of materials, ensure the uniformity of the quality of the spray materials, and thus ensure the consistency of the spraying effect.

[0051] like Fig. 9 , Fig.10 and Fig.11As shown, the stirring mechanism 4 includes a sealing tube 41, which is fixedly connected to the bottom of the center frame 31, and a sleeve net 46 is fixedly connected inside the sealing tube 41, wherein the surface of the sleeve net 46 is provided with a plurality of holes, and a motor 42 is fixedly connected to the bottom of the sleeve net 46, and the output end of the top of the motor 42 is connected to a rotating shaft 43 through a coupling, and a sleeve 44 is fixedly connected to the outer side of the rotating shaft 43, and three oblique stirring blades 45 are sleeved on the outer side of the sleeve 44, and the spraying raw materials flowing out from the through hole 3645, the first spiral auger 3642, the second spiral auger 3644 and the outlet pipe 363 respectively will all enter the sealing tube 41. The motor 42 is started at this time, so that the rotating shaft 43 connected to the output end thereof through the coupling will rotate, and the sleeve 44 fixedly connected to the outer side of the rotating shaft 43 will rotate with the three-angle stirring blade 45, wherein the three-angle stirring blade 45 has a good stirring effect: it can fully stir the materials and make different components mixed evenly; low shear force: less damage to the materials, suitable for some materials that are sensitive to shear; stable operation: relatively stable during the stirring process, reducing vibration and noise; improving efficiency: helping to improve the efficiency of the stirring process and shorten the stirring time, the bottom of the sleeve net 46 is plugged with a plugging pipe 47, the bottom of the plugging pipe 47 A hand-held handle 49 is fixedly connected to the bottom of the sleeve net 46, and an outflow hole 48 is opened at the bottom of the sleeve net 46, wherein the outflow hole 48 is located between the sleeve net 46 and the sealing tube 41. When the spraying material is stirred in the sealing tube 41 for a predetermined period of time, the operator can manually pull the hand-held handle 49 downward, and then the blocking tube 47 fixedly connected to the top of the hand-held handle 49 will be pulled out from the sleeve net 46. The blocking tube 47 initially blocks the holes on the surface of the sleeve net 46, and also blocks the outflow hole 48. However, as the blocking tube 47 is pulled out, the holes on the surface of the sleeve net 46 and the outflow hole 48 will open. In addition, accompanied by the rotation of the three oblique stirring blades 45, the spraying material will be sprayed out from the holes on the surface of the sleeve net 46, and then flow downward along the inner wall of the sealing tube 41 and through the outflow hole 48. The above-mentioned spraying material can filter impurities in the process of passing through the sleeve net 46: the mesh can play a filtering role, remove impurities and particulate matter in the liquid, and make the outflowing liquid purer; at the same time, the outflow speed can be controlled: the mesh can adjust the outflow speed of the liquid to make it more uniform and stable, which helps to accurately control the usage; easy to collect and use: make the liquid easier to collect and use, and improve work efficiency.

[0052] In addition, the adhesion of gelatin will be reduced after heating, so when it enters the interior of the central frame 31 and the interior of the stirring mechanism 4, its adhesion will be greatly reduced. At the same time, when gelatin is mixed with another non-sticky spraying material, the overall viscosity will also be greatly reduced.

[0053] The stationary mechanism 5 includes a platform 51, which is fixedly connected to the outer side of the support frame 1, and a stationary bin 52 is fixedly connected to the inner side of the platform 51. The inner wall of the stationary bin 52 is fixedly connected to a vertical rail 53. The inner sliding of the vertical rail 53 is adapted with a pressure plate 54, and the bottom of the pressure plate 54 is squeezed and adapted with a limiting column 55, and the limiting column 55 is inserted at the bottom of the stationary bin 52.

[0054] When the two spraying raw materials are mixed and before flowing out from the outflow hole 48, it is necessary to pull the pressure plate 54 upward along the vertical rail 53, and then let the mixed spraying material flow into the static bin 52 from the outflow hole. At this time, leave the material for a while to allow the bubbles to rise and disappear naturally. If the effect is poor, the pressure plate 54 can be moved downward along the vertical rail 53. At this time, the pressure of the pressure plate 54 on the spraying material can help clear the rising bubbles to a certain extent. In addition, the limiting column 55 interspersed at the bottom of the static bin 52 prevents the pressure plate 54 from being deflected during the downward movement, thereby causing more bubbles to be generated.

[0055] When the present invention is in use: first, the spraying material is put into the port at the top of the feed pipe 21. If the viscosity of the spraying material is strong, and the spraying material is gelatin, the spraying material will be agglomerated and squeeze the open hole net 26 downward. At this time, the open hole net 26 will move downward with the connecting rod 25, and then the sliding sleeve 24 fixedly connected to the bottom end of the connecting rod 25 will move downward with the polyurethane foam board 27 and the plate heating element 28 respectively. At this time, the plate heating element 28 will heat the bottom of the feed pipe 21, and then the heated spraying material will enter the center frame 31 along the inner wall of the feed pipe 21, and hit the double-headed net 33. At this time, the spraying material will be divided into two streams, one of which will follow the hollow platform 361 and the outlet pipe 363 in turn until it enters the sealing tube 41, and the other spraying material will follow the side pipe 362 and the first spiral auger 3642 or the second spiral auger 3644 in turn until it enters the sealing tube 41. Then, the motor 42 is started again, so that the rotating shaft 43 connected to its output end through the coupling will rotate with the shaft sleeve 44, and then the three oblique stirring blades 45 will rotate and mix and stir the spraying raw materials flowing down.

[0056] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
