Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a pipe mixer for multi-crosslinked CNE phenolic epoxy resin. Background Technology

[0002] CNE phenolic epoxy resin is a multifunctional glycidyl ether type epoxy resin with excellent thermal stability, mechanical strength, electrical insulation, heat resistance, and chemical resistance. With the increasing scale of integrated circuit development, there is a growing demand for denser packaging structures and higher packaging efficiency. However, the etherification step in the preparation process of o-cresol phenolic epoxy resin introduces chlorine, which is difficult to completely remove. This leads to the release of free chloride ions from the resin under high temperature and humidity conditions, corroding the leads of integrated circuits and causing them to fail, thus affecting the normal use of electronic products. Therefore, the development of highly purified, multi-crosslinked, high-performance o-cresol phenolic epoxy resin is an inevitable trend. Pipe mixers are needed in the production of paste resins. These mixers achieve uniform mixing of fluids flowing through pipes through the action of a component or mixing element. To better mix CNE phenolic epoxy resin during production, a multi-crosslinked CNE phenolic epoxy resin pipe mixer is proposed.

[0003] For example, the pipeline mixer for paste resin disclosed in the authorization announcement number CN209772022U includes an inlet pipe, a reagent dosing pipe, a flow channel limiting ring, a swirling device, an expanding pipe, and an outlet pipe. The reagent dosing pipe is fixedly connected to the upper end wall of the inlet pipe. A flow channel limiting ring is fixedly provided on the inner wall of the inlet pipe near the reagent dosing pipe. Both sides of the flow channel limiting ring are in an expanding state. The swirling device includes a fixed column, which is fixed to the inner wall of the inlet pipe. A sliding rod is fixedly provided at the end of the fixed column away from the inlet pipe. A sliding ring is movably sleeved on the outer wall of the sliding rod. A plurality of stirring blades are fixedly provided on the outer wall of the sliding ring. A limiting block is fixedly provided at the end of the sliding rod away from the fixed column.

[0004] Although it achieves the effect of increasing the uniform mixing of the added reagent and the liquid to be treated, it has a simple structure, requires no additional operating costs, and effectively saves production costs;

[0005] However, the existing mixers do not solve the problems that make it difficult to conveniently and flexibly switch between multiple pipelines for input raw materials and adjust the material discharge position in linkage. They are also not conducive to multi-stage mixing and processing of raw materials and discharging materials from different directions, which affects the effect of material mixing and processing and the flexibility of material discharge. Utility Model Content

[0006] The purpose of this invention is to provide a multi-crosslinked CNE phenolic epoxy resin pipeline mixer to solve the problems mentioned in the background art, such as the inconvenience of switching between multiple pipelines for input raw materials and adjusting the material discharge position, which is not conducive to multi-stage mixing and processing of raw materials and discharge of materials from different directions, thus affecting the effect of material mixing and processing and the flexibility of material discharge.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pipe mixer for multi-crosslinked CNE phenolic epoxy resin, comprising a support frame and a mixing pipe. The mixing pipe is installed at the top of the support frame, and a connecting frame is provided inside the mixing pipe. Two sets of first diversion plates are provided on the surface of the connecting frame, and a second diversion plate is provided on the surface of the connecting frame on one side of each of the first diversion plates. Diversion valves are symmetrically arranged on the outer wall of the mixing pipe, and a bearing frame is installed at the top of each diversion valve. A cylinder is movably installed at the top of each bearing frame, and a push arm is installed at the output end of each cylinder. A linkage arm is provided at the end of each push arm away from the cylinder, and a hinge shaft is provided at the end of each linkage arm near the push arm. The linkage arm is movably connected to the push arm through the hinge shaft.

[0008] Preferably, the end of the linkage arm away from the push arm is provided with a drive shaft, and the drive shaft is fixedly connected to the linkage arm.

[0009] Preferably, the drive shaft extends into the interior of the diverter valve and is movably connected to the diverter valve.

[0010] Preferably, each of the diverter valves has a valve body inside, and the valve body is connected to the drive shaft.

[0011] Preferably, a discharge pipe is installed at the bottom end of the mixing pipe, and the discharge pipe is connected to the mixing pipe.

[0012] Preferably, a servo motor is provided at the bottom end of the mixing pipe on one side of the discharge pipe, and the servo motor is fixedly connected to the mixing pipe.

[0013] Preferably, a gear is installed at the output end of the servo motor, and a discharge pipe is slidably disposed on the surface of the discharge pipe.

[0014] Preferably, a toothed ring is installed on the outer wall of the discharge pipe, and the gear and the toothed ring mesh with each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the mixer not only realizes convenient and flexible switching of input raw materials through multiple pipelines and linkage adjustment of material discharge position, facilitating multi-stage mixing and processing of raw materials and discharge of materials from different directions, but also improves the effect of material mixing and processing and the flexibility of material discharge.

[0016] (1) The various raw materials required for the multi-crosslinked CNE phenolic epoxy resin are respectively input into the interior of the diversion valve through the pipes on the side wall of the diversion valve and transported to the interior of the mixing tube through a set of channels inside the valve body. The raw materials are input at high speed. After entering the mixing tube, the two sets of raw materials impact each other and are mixed by the first diversion plate and the second diversion plate. When it is necessary to change the input of raw materials, the cylinder drives the push arm to move. The push arm drives the linkage arm to rotate through the hinge shaft. The linkage arm drives the valve body to rotate inside the diversion valve through the drive shaft, so as to connect another set of channels inside the valve body with another set of external pipes, thereby inputting new raw materials into the mixing tube for mixing and processing, reducing the time of changing the raw material delivery pipes, realizing convenient and flexible switching of input raw materials through multiple pipes, facilitating multi-stage mixing and processing of raw materials, and improving the mixing and processing effect.

[0017] (2) The mixed material is discharged through the discharge pipe and the discharge pipe. When it is necessary to adjust the discharge position of the raw material, the servo motor drives the gear to rotate, and the gear drives the discharge pipe to rotate through the gear ring, so as to adjust the discharge position of the discharge pipe and discharge the material from different positions. This realizes convenient linkage adjustment of the material discharge position, facilitates the discharge of material from different directions, and improves the flexibility of discharge.

[0028] Please see Figure 1-5 An embodiment of this utility model is provided: a pipe mixer for CNE phenolic epoxy resin with multiple crosslinking, including a support frame 2 and a mixing pipe 1.

Diversion valves 4 are symmetrically arranged on the outer wall of the mixing pipe 1. A bearing frame 16 is installed at the top of each diversion valve 4. A cylinder 14 is movably installed at the top of each bearing frame 16. The cylinder 14 plays a power driving role. A push arm 15 is installed at the output end of each cylinder 14.

[0029] A drive shaft 9 is provided at the end of the linkage arm 17 away from the push arm 15, and the drive shaft 9 is fixedly connected to the linkage arm 17. The drive shaft 9 extends into the interior of the diversion valve 4, and the drive shaft 9 is movably connected to the diversion valve 4. A valve body 8 is provided inside the diversion valve 4, and the valve body 8 is connected to the drive shaft 9.

[0030] Multiple raw materials required for multi-crosslinked CNE phenolic epoxy resin are fed into the interior of the diversion valve 4 through pipes on the side wall of the diversion valve 4 and then transported to the interior of the mixing pipe 1 through a set of channels inside the valve body 8. The raw materials are fed in at high speed. After entering the mixing pipe 1, the two sets of raw materials collide with each other and are mixed by the first diversion plate 6 and the second diversion plate 7. When it is necessary to change the raw material input, the cylinder 14 can be opened, which drives the push arm 15 to move. The push arm 15 drives the linkage arm 17 to rotate through the hinge shaft 18. The linkage arm 17 drives the valve body 8 to rotate inside the diversion valve 4 through the drive shaft 9, thereby connecting another set of channels inside the valve body 8 with another set of external pipes, so as to input new raw materials into the mixing pipe 1 for mixing and processing. This reduces the time for changing the raw material delivery pipes, realizes convenient and flexible switching of input raw materials through multiple pipes, facilitates multi-stage mixing and processing of raw materials, and improves the mixing and processing effect.

[0031] A discharge pipe 11 is installed at the bottom end of the mixing pipe 1, and the discharge pipe 11 is connected to the mixing pipe 1.

[0033] The mixed material is discharged through the discharge pipe 11 and the discharge pipe 3. When it is necessary to adjust the discharge position of the raw material, the servo motor 10 is turned on, and the servo motor 10 drives the gear 12 to rotate. Under the mutual meshing of the gear 12 and the gear ring 13, and the movable cooperation between the discharge pipe 3 and the discharge pipe 11, the gear 12 drives the discharge pipe 3 to rotate through the gear ring 13, thereby adjusting the discharge position of the discharge pipe 3 and discharging the material from different positions.

[0035] The various raw materials required for the multi-crosslinked CNE phenolic epoxy resin are fed into the diversion valve 4 through pipes on its side wall and then transported to the mixing pipe 1 through a set of channels inside the valve body 8. The raw materials are fed in at high speed. After entering the mixing pipe 1, the two sets of raw materials collide with each other and are mixed by the first diversion plate 6 and the second diversion plate 7. When it is necessary to change the raw material input, the cylinder 14 drives the push arm 15 to move. The push arm 15 drives the linkage arm 17 to rotate via the hinge shaft 18.
