A heating wire is placed in the tube and the gaps around it are filled with materials with good heat resistance, thermal conductivity and insulation. At the same time, the tube mouth is sealed with sealant, so sealing adhesive is a key raw material in the production of electric heating tubes.

[0003] In the prior art, some pre-mixing devices for potting glue have large deviations in the mixing ratio of glue during mixing; and some devices have accumulated liquid at the bottom, which causes the glue to deteriorate over time and also results in inconsistent ratios of newly added glue components. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies of the existing technology and propose a potting glue premixing device, which is used to solve the technical problems that the potting glue premixing device mainly produces a large deviation in the mixing ratio of glue during mixing and liquid accumulates at the bottom of some devices, causing the glue to deteriorate over time and also causing inconsistent proportions of new component glue added.

[0007] Working principle:

[0008] When the ratio of glue stored in the premixing device needs to be adjusted, first, the operator places the raw materials to be mixed of different components into the liquid injection box, and then introduces the raw materials to be mixed in the liquid injection box into the premixing box. Then, the heating table at the bottom of the premixing box is started at the same time. At this time, the operator starts the stirring component, and the stirring component stirs the glue in the premixing box, thereby stirring the glue in the premixing box evenly. After stirring evenly, the glue continuously flows into the liquid storage tank from the liquid outlet at the bottom of the premixing box for collection.

[0009] The beneficial effects of the utility model are:

[0010] In the prior art, the amount and introduction rate of the raw materials to be mixed of each component introduced into the premixing box can be controlled by setting a liquid injection component, thereby ensuring the accurate proportion of each component; the mixing temperature in the premixing box can be increased by setting a heating table, thereby further improving the stirring efficiency.

DETAILED DESCRIPTION

[0014] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0015] Example 1:

[0016] like Figure 1As shown, a potting glue premixing device includes a premixing box 2, which is cylindrical, and in this embodiment, the premixing box 2 is fixedly installed on a workbench 1. At the same time, a first gantry 6 is provided on the workbench 1, and the first gantry 6 is located above the premixing box 2. Two injection assemblies are provided above the premixing box 2. In this embodiment, it is specifically configured that two injection assemblies are fixedly installed on the first gantry 6. The two injection assemblies each include a cylinder 13, a force rod 14, a piston 15, a liquid injection box 16, a rubber discharge hose 17, a first valve 18 and a liquid injection pipe 30; the cross bar 12 is fixedly installed on On the first gantry 6, and the injection tank 16 is fixedly mounted on the cross bar 12, the injection tank 16 is cylindrical, and an observation port with a scale line is provided on the injection tank, the cylinder 13 is fixedly mounted on the top of the first gantry 6, the force rod 14 is fixedly mounted on the telescopic end of the cylinder 13 and vertically penetrates into the injection tank 16, the piston 15 is fixedly mounted on one end of the force rod 14 extending into the injection tank 16 and slidingly abuts against the inner wall of the injection tank 16, the two ends of the discharge hose 17 are respectively connected to the injection tank 16 and the premix box 2, the first valve 18 is installed on the discharge hose 17, and the injection pipe 30 is connected to the injection tank 16 On the upper side, the injection pipe 30 is used to introduce the raw materials to be mixed into the injection box 16, and a third valve is installed on the injection pipe 30; a stirring assembly that penetrates into the interior of the premixing box 2 is installed on the top of the premixing box 2, and the stirring assembly includes a motor 9, a rotating shaft 10 and six fan blades 11. The motor 9 is fixedly mounted on the top of the premixing box 2, and the rotating shaft 10 is fixedly mounted on the output end of the motor 9 and vertically downwardly penetrates into the premixing box 2. The fan blades 11 are fixedly mounted on the rotating shaft 10, and the fan blades are irregular in shape. A heating platform 3 is provided at the bottom of the premixing box 2, and the heating platform 3 includes a conical cover 4, an electric heating tube 5 and The premixing tank 2 is provided with an insulating and heat-conductive filler 29. A conical cover 4 is fixedly and sealedly mounted on the bottom of the premixing tank 2 and welded to the bottom of the premixing tank 2. An electric heating tube 5 is provided inside the conical cover 4. The insulating and heat-conductive filler 29 is made of aluminum oxide powder. The upper surface of the conical cover 4 slopes from its center to the edge. A liquid outlet 28 is provided at the bottom of the premixing tank 2, facing the edge of the conical cover 4. A liquid storage tank 8 is also provided below the premixing tank 2. The top of the premixing tank 2 has an opening and is electrically connected to the premixing tank 2. The liquid storage tank 8 is cylindrical. A feed pipe 32 is also provided at the top of the premixing tank 2.

[0017] When the glue ratio needs to be adjusted, the operator first pours an appropriate amount of glue into the premixing box 2 through the feed pipe 32. The operator then opens the third valve 31 and introduces the raw materials to be mixed into each injection box 16 through the injection pipe 30. The operator then closes the third valve 31. Next, the operator activates the cylinder 13, which drives the force-bearing rod 14 downward, which in turn drives the piston 15 downward. At the same time, the operator opens the first valve 18 on the glue discharge pipe 17. At this time, the raw materials to be mixed in the injection box 16 are squeezed into the premixing box 2 by the piston 15. The cylinder 13 can control the speed and amount of the raw materials to be mixed. Then the operator starts the motor 9, which drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the fan blades 11 to rotate, and the fan blades 11 drive the materials in the premixing box 2 to be evenly stirred. The operator also starts the heating table 3, and the electric heating tube 5 and the insulating heat-conductive filler 29 in the heating table 3 continuously transfer temperature to the conical cover 4. The stirred glue flows from the liquid outlet 28 into the liquid storage tank 8 until the glue in the liquid storage tank 8 is collected.

[0018] The third valve 31 is provided to prevent the injected raw materials to be mixed from overflowing when squeezed by the piston 15. The piston 15 driven by the cylinder 13 can inject all the raw materials to be mixed in the liquid injection box 16 into the premixing box 2, while reducing some of the raw materials to be mixed from sticking to the inner wall of the liquid injection box 16. The fan blades 11 driven by the motor 9 can evenly stir the materials in the premixing box 2. The heating table 3 can provide a suitable mixing temperature, and the conical cover 4 can prevent liquid from accumulating at the bottom of the premixing box.

[0019] like Figure 1 As shown, it also includes a temperature sensor 22, which is fixedly arranged on the inner wall of the premixing box 2, and also includes an outlet pipe 23, a glue pump 24 and a glue outlet pipe 25. The outlet pipe 23 is fixedly inserted into the liquid storage tank 8, and the glue extraction end of the glue extraction pump 24 is conductively connected to the outlet pipe 23, and the glue outlet pipe 25 is conductively connected to the glue outlet end of the glue extraction pump 24. It also includes a fixing rod 26 and a bearing sleeve 27. The fixing rod 26 is fixedly installed on the inner wall of the premixing box 2 laterally, and the bearing sleeve 27 is rotatably sleeved on the rotating shaft 10 and fixedly connected to the fixing rod 26.

[0020] The temperature inside the premix box 2 can be monitored by the temperature sensor 22, and when the glue in the liquid storage tank 8 needs to be used, the outlet pipe 23 is inserted into the liquid storage tank 8, and then the glue in the liquid storage tank 8 is transferred to the glue outlet pipe 25 through the outlet pipe 23 by the glue pump 24 for collection. When the rotating shaft 10 drives the fan blades 11 to rotate, there will be a large resistance. By setting the fixing rod 26 and the bearing sleeve 27, the rotating shaft 10 can be further stabilized.

[0021] Example 2:

[0022] like Figure 2 As shown, the difference between Example 2 and Example 1 is that it further includes a secondary mixing tube 19, one end of the secondary mixing tube 19 is conductively connected to the premixing box 2, and the other end of the secondary mixing tube 19 is conductively connected to the liquid storage tank 8; a second valve 20 for limiting the flow of glue is installed at the connection between the secondary mixing tube 19 and the liquid outlet 28, the secondary mixing tube 19 is tilted downward, and the bottom of the secondary mixing tube 19 is stepped, and a heating body 21 is installed on the plane of the bottom of the stepped secondary mixing tube 19. In this embodiment, the heating body 21 is an electric heating plate.

[0023] The second valve 20 is provided to control the speed of the glue flowing out of the premixing box 2, and to control the on / off of the glue outflow; the bottom of the secondary mixing tube 19 is provided in a stepped shape, so that a vortex can be formed at the step, further improving the mixing effect; the tilted setting of the secondary mixing tube 19 can prevent the accumulation of liquid on the secondary mixing tube 19. The principle of forming a vortex at the step of the secondary mixing tube 19 is as follows: the fluid passes through the step structure, and due to the rapid change in the geometric shape, the flowing fluid suddenly expands, causing the fluid boundary layer to separate at the separation point of the step. After separation at the step, due to the different speeds of the upper and lower sides immediately after the separation, a natural shear layer is formed, and this free shear layer develops downstream with the flow, and in the process of development, it will collide with the wall at a certain position, forming a new boundary layer after the collision, and the area before the collision forms a closed recirculation zone, and there is a rotating structural vortex in the recirculation zone.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
