Description

Technical Field

[0001] This utility model relates to the technical field of instrument transformer glue injection equipment, and in particular to an instrument transformer glue injection system. Background Technology

[0002] After the current transformer coil is wound, it needs to be placed on a carrier, and adhesive is injected into the carrier to surround the coil. The adhesive material is usually a mixture of various powder and liquid raw materials, and is manually controlled and metered, which can easily lead to inaccurate material ratios. Furthermore, uneven mixing of the materials can affect the adhesive injection effect, ultimately resulting in defective current transformers. Therefore, accurate and uniform mixing of the raw materials is crucial to the success rate of current transformer adhesive injection. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a current transformer glue injection system that provides precise material feeding and uniform mixing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a current transformer glue injection system, comprising:

[0005] A primary mixing device, comprising a first tank and a weighing mechanism, wherein the weighing mechanism is used to weigh the first tank and the first tank is capable of stirring the raw materials therein;

[0006] A secondary mixing device, comprising a second tank connected to the first tank via a first pipe, wherein the second tank is capable of stirring the raw materials therein, and a vacuum generator is connected to the second tank;

[0007] The dispensing head is connected to the second tank via a second pipe, and a flow metering pump is installed on the second pipe.

[0008] The beneficial effects of this utility model are as follows:

[0009] The primary mixing unit performs the first mixing of the raw materials, and the secondary mixing unit performs the second mixing. After the two mixing processes, the raw materials are thoroughly mixed and then injected into the adhesive through the dispensing head. Furthermore, the primary and secondary mixing units mix simultaneously, saving mixing time compared to using only one mixing unit.

[0010] The second tank can simultaneously create a vacuum while stirring the raw materials, performing defoaming treatment to eliminate the bubbles formed during stirring.

[0011] The metering pump accurately measures the raw materials entering the dispensing head, achieving precise metering and control.

[0012] Furthermore, a return pipe is connected between the dispensing head and the second tank. The return pipe, the second pipe, and the inlet of the dispensing head are all connected to a three-way valve. The inlet of the three-way valve is connected to the second pipe, and the return pipe and the inlet of the dispensing head are respectively connected to the two outlets of the three-way valve.

[0013] When the dispensing system is not in use, the heating layer stops working, and the raw material inside the pipe body will solidify, affecting subsequent use. Therefore, a return pipe is also connected between the dispensing head and the second tank, allowing the raw material in the second pipe to flow back into the second tank.

[0014] Furthermore, the secondary mixing device also includes a second stirring mechanism, which includes a stirring plate assembly and a stirring drive. The stirring plate assembly includes a rotating shaft located inside the second tank. The upper end of the rotating shaft is connected to the stirring drive, and the lower end of the rotating shaft is fixed with a stirring plate. A downwardly extending anti-sinking plate is fixed on the stirring plate, and the anti-sinking plate abuts against or has a gap with the bottom of the second tank.

[0015] Anti-sinking plates can lift up the raw materials deposited at the bottom of the second tank, preventing the raw materials from settling.

[0016] Furthermore, the anti-sinking plate is made of plastic to prevent damage to the second tank.

[0017] Furthermore, the first tank includes a first inlet and a second inlet. A buffer pipe that can communicate with the first tank is provided at the first inlet. The buffer pipe and the second inlet are supplied with different raw materials through feeding pipes, respectively. A switch valve for opening and closing the first inlet is provided between the buffer pipe and the first tank.

[0018] The buffer tube measures the amount of raw material entering it.

[0019] Furthermore, the current transformer glue injection system also includes a drying oven, which includes a furnace body and a conveyor line passing through the furnace body. The two ends of the conveyor line pass through the furnace body and are respectively the feeding end and the unloading end. The glue injection head is located at the feeding end.

[0020] Furthermore, the feeding end is also equipped with a three-axis moving platform, and the glue injection head is fixed at the output end of the three-axis moving platform to adjust the position of the glue injection head for easy glue injection.

[0021] Furthermore, there is one primary mixing device, and multiple secondary mixing devices and dispensing heads are provided in a one-to-one correspondence, with each of the multiple secondary mixing devices connected to the primary mixing device.

[0022] The first tank of the primary mixing device and the second tank of the secondary mixing device correspond one-to-one, and the dispensing head is connected to all the second tanks of the secondary mixing device.

[0023] Furthermore, both the first and second pipes include a pipe body and a heating layer encasing the pipe body. The heating layer heats the raw materials passing through the first and second pipes, preventing them from solidifying. A diaphragm pump is connected to the pipe body to provide power, and the diaphragm pump draws in material, making feeding more convenient.

[0024] Furthermore, the current transformer glue injection system also includes a cleaning mechanism for cleaning the glue injection head. The cleaning mechanism includes a cleaning agent supply device, which is connected to the glue injection head via a cleaning pipe. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] See appendix Figure 1 As shown, this utility model discloses a current transformer glue injection system. The current transformer glue injection system includes a primary mixing device 1, a secondary mixing device 2, and a glue injection head 3. The primary mixing device 1 performs a first mixing of the raw materials, and the secondary mixing device 2 performs a second mixing of the raw materials. After the two mixing processes, the raw materials are uniformly mixed, and then glue is injected through the glue injection head 3. Moreover, the primary mixing device 1 and the secondary mixing device 2 mix simultaneously, which saves mixing time compared to using only one mixing device.

[0044] The primary mixing device 1 includes a first tank 11 and a weighing mechanism 12. The weighing mechanism 12 is used to weigh the first tank 11, which can stir the raw materials inside. The weighing mechanism 12 weighs the first tank 11 to ensure that the weight of the raw materials in the first tank 11 is in accordance with the specified ratio for mixing. The secondary mixing device 2 includes a second tank 21, which is connected to the first tank 11 through a first pipe. The second tank 21 can stir the raw materials inside and is connected to a vacuum generator 7. The second tank 21 can simultaneously create a vacuum while stirring the raw materials to perform defoaming treatment and eliminate the bubbles formed during stirring. The dispensing head 3 is connected to the second tank 21 through a second pipe, on which a metering pump is installed. The metering pump accurately measures the raw materials entering the dispensing head 3, achieving precise metering and control.

[0045] The current transformer glue injection system in this embodiment stirs the raw materials twice to ensure uniform mixing and saves stirring time. During the second stirring, a vacuum can be drawn simultaneously to perform degassing.

[0046] See appendix Figure 1 As shown, there is one primary mixing device 1, and multiple secondary mixing devices 2 and dispensing heads 3 are arranged in a one-to-one correspondence, with each secondary mixing device 2 connected to the primary mixing device 1. After initial mixing by the primary mixing device 1, the material undergoes fine mixing by multiple secondary mixing devices 2 to ensure the discharge rate. Simultaneously, one secondary mixing device 2 supplies material to one dispensing head 3. The first tank 11 of the primary mixing device 1 and the second tank 21 of each secondary mixing device 2 correspond one-to-one, and each dispensing head 3 is connected to all the second tanks 21 of each secondary mixing device 2.

[0047] In one embodiment, the primary mixing device 1 includes two first tanks 11, one of which mixes epoxy resin and silicone powder, and the other of which mixes curing agent and silicone powder. Each secondary mixing device 2 also includes two second tanks 21, which are respectively connected to the two first tanks 11.

[0048] See appendix Figure 2 As shown, the first tank 11 includes a first inlet and a second inlet 112. A buffer pipe 111 that can communicate with the first tank 11 is provided at the first inlet. The buffer pipe 111 and the second inlet 112 are supplied with different raw materials through feeding pipes. A switch valve 1111 for opening and closing the first inlet is provided between the buffer pipe 111 and the first tank 11.

[0049] The buffer tube 111 contains powdered silicon powder. Only when the buffer tube 111 is full of silicon powder (a standard amount) will the switch valve 1111 open, allowing the silicon powder to enter the first tank 11. After the specified amount of silicon powder from the buffer tube 111 enters the first tank 11, liquid epoxy resin or curing agent enters the first tank 11 through the second inlet 112. The weighing mechanism 12 weighs the first tank 11 in real time. When the first tank 11 reaches the specified weight, the specified weight of epoxy resin or curing agent has been added. At this point, the silicon powder and epoxy resin / curing agent have reached the set ratio, and stirring can begin.

[0050] See appendix Figure 2 As shown, all the first tanks 11 are fixed on a first stand 13, and the weighing mechanism 12 is a weight sensor fixed on the first stand 13. The weight sensor weighs the first tanks 11.

[0051] The primary mixing device 1 includes a first stirring mechanism, which stirs the raw materials in the first tank 11. The first stirring mechanism is a conventional stirring mechanism, including a drive component and a stirring plate 223, etc.

[0052] See appendix Figure 3 and attached Figure 4 As shown, the secondary mixing device 2 further includes a second stirring mechanism 22. The second stirring mechanism 22 includes a stirring plate 223 assembly and a stirring drive component 221. The stirring plate 223 assembly includes a rotating shaft 222 located inside the second tank 21. The upper end of the rotating shaft 222 is connected to the stirring drive component 221, and the lower end of the rotating shaft 222 is fixed to the stirring plate 223. A downwardly extending anti-sinking plate 224 is fixed on the stirring plate 223, and the anti-sinking plate 224 abuts against the bottom of the second tank 21. Because the bottom of the second tank 21 has a concave arc structure, it is prone to material accumulation. The addition of the anti-sinking plate 224, which abuts against the bottom of the second tank 21, can lift the raw materials deposited at the bottom of the second tank 21. Because the second tank 21 is made of metal, the anti-sinking plate 224 is made of plastic to avoid damage.

[0053] In one embodiment, a gap is left between the anti-sinking plate 224 and the bottom of the second tank 21. This gap cannot be too large, but it is still sufficient to lift any raw materials deposited at the bottom of the second tank 21, preventing further sedimentation. The anti-sinking plate 224 is fan-shaped, matching the shape of the bottom of the second tank 21.

[0054] In one embodiment, the anti-sinking plate 224 is fixedly connected to the stirring plate 223 by bolts. The stirring plate 223 has a vertically arranged waist-shaped hole, and the bolts can slide in the waist-shaped hole to adjust the height of the dustproof plate.

[0055] Both the first tank 11 and the second tank 21 employ a dynamic and static mixing and stirring mode to ensure thorough mixing of the raw materials. Furthermore, both the first and second tanks 21 are equipped with viewing windows to observe the mixing status of the raw materials within.

[0056] In one embodiment, both the first and second pipes include a pipe body and a heating layer enclosing the pipe body, with a diaphragm pump connected to the pipe body to provide power. The heating layer is added to prevent the raw material from cooling within the pipe body.

[0057] When the dispensing system is not in use, the heating layer stops working, and the raw material inside the pipe body will solidify, affecting subsequent use. Therefore, a return pipe is also connected between the dispensing head 3 and the second tank 21, so that the raw material in the second pipe can flow back into the second tank 21 through the return pipe.

[0058] The return pipe, the second pipe, and the inlet of the dispensing head 3 are all connected to a three-way valve. The inlet of the three-way valve is connected to the second pipe, and the return pipe and the inlet of the dispensing head 3 are respectively connected to the two outlets of the three-way valve. During dispensing, the second pipe and the inlet of the dispensing head 3 are connected, and the second pipe and the return pipe are disconnected. When recirculation is required, the three-way valve is turned, the second pipe and the inlet of the dispensing head 3 are disconnected, and the second pipe and the return pipe are connected. The raw material remaining in the second pipe can flow back to the second tank 21 through the return pipe.

[0059] The current transformer glue injection system also includes a cleaning mechanism for cleaning the glue injection head 3. The cleaning mechanism includes a cleaning agent supply device 6, which is connected to the glue injection head 3 via a cleaning pipe.

[0060] See appendix Figure 3 As shown, the cleaning agent supply device 6 and the second tank 21 are jointly fixed on the second support 23. The cleaning agent supply device 6 includes a supply tank and a pump that provides power for the flow of the cleaner within the cleaning pipe. When necessary, the dispensing head 3 is cleaned by a cleaning mechanism to clean the dispensing channel inside the dispensing head 3.

[0061] See appendix Figure 1 As shown, the instrument transformer glue injection system also includes a drying oven 5. The drying oven 5 includes an oven body 51 and a conveyor line 52 passing through the oven body 51. The two ends of the conveyor line 52 pass through the oven body 51 and are respectively the loading end and the unloading end. The glue injection head 3 is located at the loading end. After the glue injection head 3 injects glue into the instrument transformer at the loading end, the instrument transformer enters the oven body 51 under the drive of the conveyor line 52 for drying, which facilitates curing.

[0062] See appendix Figure 1As shown, the feeding end is also equipped with a three-axis moving platform 4, and the glue injection head 3 is fixed to the output end of the three-axis moving platform 4. The position of the glue injection head 3 can be adjusted by the three-axis moving platform 4 to facilitate glue injection.

[0063] The three-axis moving platform 4 is a manual platform, which is manually pulled to move the dispensing head 3. Of course, in some embodiments, the three-axis moving platform 4 can also be an automatic platform, consisting of three linear modules that work together to move the dispensing head 3 in three directions respectively.

[0064] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
