Description

Technical Field

[0001] The invention belongs to the technical field of transformer production, and in particular relates to a multi-mode insulating paper glue liquid conveying device. Background Art

[0002] Insulation is an important component in a transformer, and the insulation capacity of the transformer has a significant impact on its performance and lifespan. In the production of insulation, it is often necessary to use glue to bond the insulating paper to the required thickness and solidify it into the required shape. The role of glue in the manufacture of insulation is very important. Glue often has an important characteristic, that is, the unpacked or taken out glue needs to be used up within a certain period of time, otherwise its viscosity and fluidity will change, which will affect the bonding performance. Therefore, at the production site, there is often a professional glue storage place, and the operator takes it out from the storage place for use according to demand and quantity. Therefore, the production site needs to conveniently take out a certain amount of glue from the storage tank. Summary of the Invention

[0003] The present invention provides a multi-mode insulating paper glue liquid conveying device to solve the problems in the above-mentioned background technology.

[0004] The technical problem solved by the present invention is achieved by adopting the following technical solutions:

[0005] A multi-mode insulating paper glue liquid conveying device comprises a shell, a valve core, a back cover, a first box body and a second box body. The back cover covers the valve core in the shell body, and the first box body and the second box body are respectively connected to the shell body.

[0006] The housing consists of a front shell, a center hole, pipe joints, and a main rubber hose. The housing is open at the rear, with a center hole in the center of the front shell and three pipe joints on the upper sidewalls. The axes of the three pipe joints are oriented toward the axis of the housing. The middle pipe joint is connected to the main rubber hose, which extends upward to the rubber storage tank. The rubber outlet is located directly below the housing. The valve core includes an operating lever, a valve block, a first valve position, a retaining ring, a second valve position, a tail rod, and a large spring. The front end of the valve block is connected to the operating lever, which extends through the center hole and out of the housing. The side walls of the valve block are equipped with a first valve position, a retaining ring, and a second valve position. The retaining ring separates the first and second valve positions and has a notch around its perimeter. The first valve position has two states: one in which the main hose simultaneously supplies glue to both tanks, and the other in which the main hose directly delivers glue outward without controlling the weight. The second valve position has three states: one is completely shut off; the second is in which the first tank delivers glue outward while the main hose delivers glue to the second tank; and the third is in which the second tank delivers glue outward while the main hose delivers glue to the first tank. The top of the first valve position also features a three-pronged dual-position glue-feeding groove. When the dual-position glue-feeding groove is aligned with the position of the pipe joint, glue flows from the main hose to both glue tanks simultaneously. The top of the second valve position features a side flow channel, with a first flow channel and a second flow channel on each side of the second valve position. The first flow channel serves as the docking flow channel for the first tank, and the second flow channel serves as the docking flow channel for the second tank. The rear of the valve block is connected to the tail rod. The outer wall of the rear of the tail rod has two sets of evenly distributed limit nests. The spacing between the two sets of limit nests is equal to the spacing between the first valve position and the second valve position. The tail rod has a blind hole inside, and a large spring is installed in the blind hole. The rear cover includes a cover body, a rear tube, a side tube, a plug cover, a tightening screw, a small spring and a ball. The cover body covers the valve core in the shell from the rear. The rear of the cover body has a hollow rear tube. The tail rod is inserted into the rear tube. The rear tube extends upward to the side tube. The ball, small spring and tightening screw are installed in the side tube from bottom to top. The small spring presses the ball into the limit nest. The plug cover is installed at the rear of the rear tube to cover and seal the entire device.

[0007] The first chamber includes a cavity, a rubber delivery hose, a vent pipe, and a plug. The cavity serves as a temporary storage space for the glue liquid. The volume of the cavity is set according to the needs, that is, the amount required for quantitative output. The bottom of the cavity is connected to the pipe joint via the rubber delivery hose, and the top of the cavity has a vent pipe. The basic structure of the second chamber is the same as that of the first chamber. Depending on the needs, the volumes of the two chambers can be set to the same or designed separately, completely according to the needs of the production site.

[0008] Furthermore, the outer wall of the front shell has a scale plate, and the scale plate has inner and outer scales. The inner scale plate indicates the position of the valve core of the second valve position, and the outer scale plate indicates the position of the valve core of the first valve position.

[0009] Furthermore, the angle between the axes of the three pipe joints is 45°, and the pipe joint in the middle faces directly upward.

[0010] Furthermore, the front end of the operating rod has a mounting groove, and a handle is installed on the mounting groove. A pointer can also be set for the handle, and the position status of the valve core is indicated by the cooperation of the pointer and the dial.

[0011] Furthermore, a through hole is provided inside the first valve position. When the through hole is rotated to a vertical position, the glue flows into the through hole through the main glue pipe and flows out downward, forming a variable amount of glue delivery channel.

[0012] Furthermore, the two branches of the lateral flow channel each form an angle of 22.5° with the vertical direction.

[0013] Furthermore, the angle between two adjacent limiting recesses in the same group is 22.5°, the limiting recesses in the same group are connected by a shallower axial groove, and the corresponding points of the two groups of limiting recesses are connected by an axial groove.

[0014] Furthermore, the top of the clamping screw is provided with a slotted groove, which facilitates the use of tools to install the clamping screw and adjust the clamping force.

[0015] Furthermore, a plug is installed in the vent pipe, which can be used to block or ventilate the vent pipe as needed. The plug has an air hole on the top and a float at the bottom.

[0016] The beneficial effects of the present invention are:

[0017] The present invention is used for quantitatively dispensing adhesive used in the manufacture of insulating components during transformer production. It provides three modes: complete shutdown, direct, variable adhesive dispensing, and one box dispensing adhesive quantitatively while the other box replenishes it. This allows for easy, simple operation at the production site to obtain the required adhesive as needed. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive disclosure of the present invention.

[0026] See also Figures 1-6 The multi-mode insulating paper glue liquid conveying device shown includes a shell 10, a valve core 20, a back cover 30, a first box body 40 and a second box body 50. The back cover 30 covers the valve core 20 in the shell 10, and the first box body 40 and the second box body 50 are respectively connected to the shell 10.

[0027] The housing 10 includes a front housing 11, a center hole 12, a scale plate 13, a pipe joint 14 and a main hose 15. The housing 10 is a rear open structure. The center of the front housing 11 has a center hole 12. The outer wall of the front housing 11 has a scale plate 13. The scale plate 13 has two inner and outer scales. The inner scale indicates the position of the valve core of the second valve position 25, and the outer scale indicates the position of the valve core of the first valve position 23. The upper part of the side wall of the front housing 11 has three pipe joints 14. The axes of the three pipe joints 14 are toward the axis of the housing 10. The angle between the axes of the three pipe joints 14 is 45°. The middle pipe joint 14 faces directly upward. The pipe joint 14 is connected to the main rubber hose 15, which is connected to the storage tank of the glue. The main rubber hose 15 receives the glue from the storage tank and flows downward as needed under the control of this embodiment. There is a glue outlet directly below the shell 10 (not visible in the figure due to the angle problem). The glue outlet can also be provided with a component similar to the pipe joint 14 as needed to facilitate the outflow and reception of the glue.

[0028] The valve core 20 includes an operating rod 21, a valve block 22, a first valve position 23, a retaining ring 24, a second valve position 25, a tail rod 26 and a large spring 27. The front end of the valve block 22 is connected to the operating rod 21, and the operating rod 21 passes through the housing 10 from the center hole 12. The front end of the operating rod 21 has a mounting groove 211, and a handle (not shown in the figure) is installed on the mounting groove 211. A pointer can also be set for the handle to indicate the position status of the valve core 20 through the cooperation of the pointer and the dial 13.

[0029] The side walls of the valve block 22 respectively have a first valve position 23, a retaining ring 24, and a second valve position 25. The retaining ring 24 separates the first valve position 23 and the second valve position 25. The retaining ring 24 has a notch 241 around it, so that the rubber pipe installed in the pipe joint 14 and against the side wall where the second valve position 23 is located slides from the notch 241 to switch the positions of the two valve positions. The first valve position 23 has two states, one is that the main rubber pipe 15 replenishes rubber liquid to the two boxes at the same time, and the other is that the main rubber pipe 15 directly delivers rubber liquid outward without controlling the weight; the second valve position 25 has three states, one is completely shut down, the second is that the first box 40 delivers rubber liquid outward while the main rubber pipe 15 replenishes rubber liquid to the second box 50, and the third is that the second box 50 delivers rubber liquid outward while the main rubber pipe 15 replenishes rubber liquid to the first box 40.

[0030] like Figure 5 As shown, the first valve position 23 has a through hole 231 inside. When the through hole 231 is rotated to a vertical position, the glue flows into the through hole 231 through the main rubber tube 15 and flows downward, forming an indefinite glue delivery channel. The upper part of the first valve position 23 also has a three-pronged double-position glue replenishing groove 232. When the double-position glue replenishing groove 232 is aligned with the position of the pipe joint 14, the glue flows from the main rubber tube 15 to the two glue boxes at the same time, that is, the glue is replenished to the two boxes at the same time for distribution.

[0031] like Figure 6As shown, the upper part of the second valve position 25 is provided with a side flow channel 252, and the two branches of the side flow channel 252 are respectively at an angle of 22.5° to the vertical direction. The second valve position 25 is provided with a first flow channel 251 and a second flow channel 253 on both sides. The first flow channel 251 is a docking flow channel of the first box body 40, and the second flow channel 252 is a docking flow channel of the second box body 50. When the valve core 20 rotates to the point where the first flow channel 251 is aligned with the pipeline of the first box body 40, the glue in the first box body 40 flows downward from the first flow channel 251. At the same time, the two ends of the side flow channel 252 are respectively aligned with the main rubber hose 15 and the second box body 50 to replenish the glue for the next step to be transported outward. The working principle of the second flow channel 253 is similar. It should be noted here that since the directions of the first flow channel 251 and the second flow channel 253 will inevitably intersect, the middle section of the first flow channel 251 and the middle section of the second flow channel 253 need to be staggered in the axial direction of the valve core 20. This arrangement naturally increases the manufacturing difficulty of the valve core 20. However, those skilled in the art have many process methods to achieve this.

[0032] like Figure 4 As shown, the rear of the valve block 22 is connected to the tail rod 26. The rear outer wall of the tail rod 26 has two sets of evenly spaced limiting recesses 261. The spacing between the two sets of limiting recesses 261 is equal to the spacing between the first valve position 23 and the second valve position 25. The angle between two adjacent limiting recesses 261 in the same group is 22.5 degrees. The limiting recesses 261 in the same group are connected by a shallow axial groove 262, and the corresponding points of the two sets of limiting recesses 261 are connected by an axial groove 263. The tail rod 26 has a blind hole 264 inside, and a large spring 27 is installed in the blind hole 264. The large spring 27 cooperates with the rear cover 30 to control the position of the valve core 20. Under the action of the large spring 27, the initial position of the valve core 20 is the second valve position 25, corresponding to the position of the pipe joint 14.

[0033] The rear cover 30 includes a cover body 31, a rear tube 32, a side tube 33, a plug cover 34, a clamping screw 35, a small spring 36, and a ball 37. The cover body 31 covers the valve core 20 in the housing 10 from the rear. The rear of the cover body 30 has a hollow rear tube 32, and the tail rod 26 is inserted into the rear tube 32. The rear tube 32 extends upward from the side tube 33. The ball 37, small spring 36, and clamping screw 35 are installed in the side tube 33 from bottom to top. The small spring 36 presses the ball 37 into the limit socket 261, limiting the position of the valve core 20 and providing a prompt for the rotation angle. The top of the clamping screw 35 has a straight groove 351, which facilitates the use of tools to install the clamping screw 35 and adjust the clamping force. The plug cover 34 is installed at the rear of the rear tube 32 to cover and seal the entire device.

[0034] The first box body 40 includes a cavity 41, a glue delivery pipe 42, a vent pipe 43 and a plug 44. The cavity 41 is a temporary storage space for the glue. The volume of the cavity 41 is set according to needs, that is, the amount required for quantitative output. The bottom of the cavity 41 is connected to the pipe joint 14 through the glue delivery pipe 42. The top of the cavity 41 has a vent pipe 43. The glue needs to be ventilated during the filling and discharging process in the cavity 41. A plug 44 is installed in the vent pipe 43. The plug 44 seals or ventilates the vent pipe 43 as needed. The plug 44 has an air hole 441 on the top and a float 442 on the bottom. When the glue in the cavity 41 is not full, the plug 44 automatically falls down by gravity. At this time, the float 442 is connected to the bottom of the vent tube 43 and the air hole 441 to the air, and the glue can flow into the cavity 41. When the glue in the cavity 41 is gradually filled, the float 442 floats upward under the action of the glue until the float 442 blocks the bottom of the vent tube 43. At this time, the cavity 41 is no longer ventilated to the outside, and there is no other passage. The glue can no longer enter the cavity 41, nor will it overflow the cavity 41, and the predetermined capacity of glue is obtained.

[0035] The basic structure of the second box body 50 is consistent with that of the first box body 40. As needed, the volumes of the two boxes can be set to be consistent, or the volumes of the two boxes can be designed separately as needed, which can be set entirely according to the needs of the production site.

[0036] Finally, it should be added that the sealing connection is required at many places in this embodiment, which is easy to implement for those skilled in the art and will not be described in detail here. In addition, in order to ensure a stable connection, there should be other connecting brackets between the device of this embodiment and the storage tank of the glue.

[0037] The working principle of the present invention is as follows: in the initial state, the position of the second valve position 25 corresponds to the position of the pipe joint 14. In the absence of any operation, the entire device is in a completely closed state. First, the valve core 20 is pressed backward through the operating rod 21 to align the double-position glue filling groove 232 of the first valve position 23 with the upper pipe joints 14. At this time, the main rubber hose 15 replenishes glue to the two boxes at the same time. By observing whether the plug 44 is pushed upward, it is determined whether the two boxes are full of glue. After the two boxes are full of glue, the operating rod 21 is released and the valve core 20 returns to its initial position. When it is necessary to transport glue outward, turn the operating rod 21 to the left or right, the rotation angle is 22.5 degrees, and you can get a prompt from the cooperation between the ball 37 and the limit socket 261, or you can get an angle indication from the dial 13. Press Figure 1In the orientation shown, rotating to the left corresponds to the first box 40 outputting glue liquid outward. At this time, one end of the first flow channel 251 is aligned with the glue delivery pipe 42, and the other end is aligned directly downward. The glue liquid in the first box 40 flows out from the opening directly below the shell 10. At the same time, the side flow channel 252 also rotates 22.5°. At this time, the main glue hose 15 is connected to the second box 50 to replenish the glue liquid to the second box 50. Of course, if the second box 50 has been replenished through the above operation, the glue liquid will no longer circulate in this passage. It should be supplemented in this link that when the first box 40 is full of glue liquid, the float 442 of the plug 44 has a blocking effect on the vent pipe 43 of the first box 40. Then, the initial stage of the first box 40 outputting glue liquid is to rely on the gravity of the glue liquid itself to flow downward. As the glue liquid flows downward, the plug 44 moves downward with the glue liquid and forms ventilation again at the vent pipe 43, accelerating the downward flow of the glue liquid. After the glue liquid in the first box 40 is outputted, the valve core 20 can be directly rotated to the right as needed. Similarly, the glue liquid in the second box 50 is immediately transported out and the glue liquid is replenished to the first box 40. This greatly improves the efficiency of the quantitative output of the glue liquid.

[0038] In addition, a valve can be added to the main rubber hose 15 as needed. On the basis of the above operation, the passage of the main rubber hose 15 can be shut off, so that the glue liquid is output only through one of the boxes and the glue liquid is stopped from being replenished to the other box, thereby realizing the emptying operation of the two boxes. It is mainly used for the last glue liquid output before leaving get off work to avoid the glue liquid in the two boxes being stored overnight.

[0039] Finally, if a large amount of glue needs to be output and the amount does not need to be controlled, the valve core 20 can be pressed backward and rotated 90°. At this time, the straight hole 231 is directly connected to the main glue pipe 15 and the bottom opening, and the glue is directly output to the outside.

[0040] The above embodiments primarily illustrate the multi-mode insulating paper glue delivery device of the present invention. While only a limited number of embodiments and technical features have been described, those skilled in the art will appreciate that the present invention may be implemented in numerous other forms without departing from its spirit and scope. Therefore, the illustrated embodiments are to be considered illustrative rather than restrictive, and the present invention may encompass various modifications and alternatives without departing from the spirit and scope of the present invention as defined by the appended claims.
