Description

Technical Field

[0001] This utility model relates to the technical field of impregnation equipment, specifically to an impregnation equipment for glass fiber wrapped wire. Background Technology

[0002] A glass fiber enamel impregnation apparatus is a device used to manufacture glass fiber enamel (also called glass fiber-insulated wire). It improves the insulation properties and mechanical strength of the glass fiber enamel through an impregnation process.

[0003] The existing glass fiber-insulated wire impregnation device works as follows: first, the wire is placed in the impregnation tank. When the wire passes through the outlet hole on the felt, the felt removes excess paint and controls the thickness of the paint film through friction and adsorption.

[0004] Although this method can complete the impregnation of glass fiber-wrapped wire, the following problems still exist: 1. The existing technology is a primitive impregnation process. The amount of paint coating on the product needs to be controlled by the tightness of the wool felt. Therefore, controlling the paint film thickness by relying on the tightness of the wool felt is basically based on personal experience, resulting in different paint film thicknesses at different production sites by different workers.

[0005] 2. Because traditional dipping paint cannot penetrate deeply, the dipping process must go through multiple dipping steps, which affects production efficiency and easily leads to paint waste.

[0006] 3. The products come in a variety of sizes and specifications, and new felt must be used every time a product is changed, which not only wastes felt but also extends production time;

[0007] 4. Since the thickness of the varnish film is controlled by the felt, friction will occur when the felt comes into contact with the varnish film, which will damage the insulation surface. Utility Model Content

[0008] This invention proposes a glass fiber-coated wire impregnation device, which solves the problem of the limited wire size produced by existing impregnation devices and improves the practicality of the equipment.

[0009] The technical solution of this utility model is as follows:

[0014] Furthermore, the adjustment structure includes a first lead screw, a second lead screw, a first sliding rod, and a second sliding rod. The first lead screw has a first thread and a second thread on both sides, with the first thread and the second thread having opposite directions of rotation. The first mounting part is threadedly connected to the first thread, and the second mounting part is threadedly connected to the second thread.

The third mounting part is threadedly connected to the third thread, and the fourth mounting part is threadedly connected to the fourth thread.

[0015] Furthermore, there are two of each of the first and second adjustment frames, with each second adjustment frame positioned between the first adjustment frames.

[0016] Furthermore, the correction structure includes a third adjustment frame, which has the same structure as the first adjustment frame.

[0017] Furthermore, the fixed frame is also equipped with a paint storage box. The bottom of the placement cavity near the first and second adjustment frames is provided with an oil inlet. The paint storage box is located at the lower end of the oil inlet. A booster pump is connected to the side wall of the paint storage box and is connected to the paint impregnation structure.

[0018] Furthermore, the impregnation structure includes a first impregnation tank and a second impregnation tank, and a fourth adjusting frame is provided between the first impregnation tank and the second impregnation tank. The fourth adjusting frame has the same structure as the second adjusting frame, and felt blocks are fixed on both sides of the first impregnation tank and the second impregnation tank.

[0019] The working principle and beneficial effects of this utility model are as follows:

At the same time, the second lead screw on the second adjusting frame is adjusted so that both sides of the third and fourth paint film adjusting rollers can contact the wire. Finally, the movement of the wire is controlled by the wire feeding device and the wire take-up device to complete the impregnation process.

[0021] This utility model installs a paint-dipping box on a fixed frame and sets up a paint-dipping structure inside the paint-dipping box. By adjusting the structure, the distance between the paint film adjusting rollers is adjusted and controlled, which replaces the existing technology of directly setting felt at the outlet of the paint-dipping tank for paint filtration.

[0032] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0033] like Figures 2-5 As shown in the figure, this embodiment proposes a glass fiber wire impregnation device, including a fixed frame. In this embodiment, the impregnation tank 2 is mounted on the fixed frame 1, and the placement cavity 21 is disposed inside the impregnation tank 2. The impregnation structure is disposed inside the placement cavity 21 for impregnating the wire. The wire inlet 217 and the wire outlet 218 are disposed on both sides of the placement cavity 21. The straightening structure is disposed on the side of the placement cavity 21 near the wire inlet 217 for straightening and positioning the wire. A plurality of varnish adjusting rollers are disposed on the side of the placement cavity 21 near the wire outlet 218. The adjusting structure is disposed inside the placement cavity 21 for controlling the spacing between adjacent varnish adjusting rollers.

[0034] In this embodiment, several first adjusting frames 213 and several second adjusting frames 214 are fixedly disposed in the placement cavity 21. First mounting members 2131 and second mounting members 2132 are slidably disposed on each of the first adjusting frames 213. First paint film adjusting rollers 21311 are rotatably disposed on each of the first mounting members 2131. Second paint film adjusting rollers 21321 are rotatably disposed on each of the second mounting members 2132. Third mounting members 2141 and fourth mounting members 2142 are slidably disposed on each of the second adjusting frames 214. Third paint film adjusting rollers 21411 are rotatably disposed on each of the third mounting members 2141. Fourth paint film adjusting rollers 21421 are rotatably disposed on each of the fourth mounting members 2142. First paint film adjusting rollers 21311 and second paint film adjusting rollers 21321 are parallel to each other. Third paint film adjusting rollers 21411 and fourth paint film adjusting rollers 21421 are parallel to each other. First paint film adjusting rollers 21311 and third paint film adjusting rollers 21411 are perpendicular to each other. In this embodiment, the first paint film adjusting roller 21311, the second paint film adjusting roller 21321, the third paint film adjusting roller 21411 and the fourth paint film adjusting roller 21421 are used to press the wire. This not only adjusts the paint film thickness on the surface of the wire, but also ensures that the paint film can enter the surface of the wire through pressing and forming, resulting in more complete coating.

[0035] The adjustment structure in this embodiment includes a first telescopic member 61 and a second telescopic member 62. The fixed end of the first telescopic member 61 is fixedly connected to the first adjustment frame 213, the telescopic end of the first telescopic member 61 is fixedly connected to the first mounting member 2131, the second mounting member 2132 is fixedly connected to the first adjustment frame 213, the fixed end of the second telescopic member 62 is fixedly connected to the second adjustment frame 214, the telescopic end of the second telescopic member 62 is fixedly connected to the third mounting member 2141, and the fourth mounting member 2142 is fixedly connected to the second adjustment frame 214. The telescopic member used in this embodiment is preferably a hydraulic cylinder or a pneumatic cylinder. Hydraulic cylinders and pneumatic cylinders are existing technologies and will not be described in detail in this embodiment. This embodiment controls and adjusts the thickness of the paint film through the first telescopic member 61 and the second telescopic member 62. Because the telescopic rod has a certain buffering capacity, the operation of the telescopic rod is relatively stable, unlike mechanical systems which have excessive vibration or noise, making it particularly suitable for applications requiring high stability and low noise.

[0036] In this embodiment, there are two first adjusting frames 213 and two second adjusting frames 214, with each second adjusting frame 214 positioned between the first adjusting frames 213. This design using two first adjusting frames 213 and two second adjusting frames 214 ensures that the wire can be limited from multiple positions, resulting in more accurate wire positioning.

[0037] The correction structure in this embodiment includes a third adjustment frame 215, which has the same structure as the first adjustment frame 213. This embodiment uses the correction structure to pre-correct and position the wire entering the impregnation tank 2, ensuring that the wire is positioned and fixed from both sides of the impregnation tank 2, preventing skew or misalignment of the wire after it passes through the impregnation tank 2.

[0038] In this embodiment, the fixed frame 1 is also equipped with a paint storage tank 3. The bottom of the placement cavity 21, near the first adjusting frame 213 and the second adjusting frame 214, is provided with an oil inlet 31. The paint storage tank 3 is located at the lower end of the oil inlet 31. A booster pump 4 is connected to the side wall of the paint storage tank 3, and the booster pump 4 is connected to the impregnation structure. In this embodiment, the paint storage tank 3 is used to collect the paint that has been pressed and filtered onto the surface of the wire by the first paint film adjusting roller 21311, the second paint film adjusting roller 21321, the third paint film adjusting roller 21411, and the fourth paint film adjusting roller 21421, and the paint in the paint storage tank 3 is then returned to the impregnation tank 2 by the booster pump 4, thus avoiding paint waste.

[0039] The impregnation structure in this embodiment includes a first impregnation tank 211 and a second impregnation tank 212. A fourth adjusting frame 216 is disposed between the first impregnation tank 211 and the second impregnation tank 212. The fourth adjusting frame 216 has the same structure as the second adjusting frame 214. Felt blocks 2111 are fixedly disposed on both sides of the first impregnation tank 211 and the second impregnation tank 212. In this embodiment, felt blocks 2111 are installed and fixed at both ends of the first impregnation tank 211 and the second impregnation tank 212 to ensure that residual paint on the wire body can be wiped off and reduce paint overflow in the impregnation tank 2.

[0040] Example 2:

[0041] Based on Example 1, this embodiment makes the following modifications to more precisely adjust the thickness of the paint film:

[0042] like Figures 6-7As shown, the adjustment structure in this embodiment includes a first lead screw 2134, a second lead screw 2143, a first sliding rod 2133, and a second sliding rod 2144. A first thread 21341 and a second thread 21342 are disposed on both sides of the first lead screw 2134, with opposite rotation directions. A first mounting member 2131 is threadedly connected to the first thread 21341, and a second mounting member 2132 is threadedly connected to the second thread 21342. Both the first mounting member 2131 and the second mounting member 2132 are slidably connected to the first sliding rod 2133. A third thread 21431 and a fourth thread 21432 are disposed on both sides of the second lead screw 2143. A third mounting member 2141 is threadedly connected to the third thread 21431, and a fourth mounting member 2142 is threadedly connected to the fourth thread 21432. In this embodiment, the distance between the first paint film adjusting roller 21311 and the second paint film adjusting roller 21321 is controlled by the first lead screw 2134 and the second lead screw 2143. Since the first thread 21341 and the second thread 21342 rotate in opposite directions, the first paint film adjusting roller 21311 and the second paint film adjusting roller 21321 can move towards each other simultaneously or away from each other, thus improving the adjustment efficiency. Moreover, since the first mounting member 2131 and the second mounting member 2132 cannot drive the first lead screw 2134 to rotate in the opposite direction, when the first lead screw 2134 is de-energized, the first mounting member 2131 and the second mounting member 2132 can form a self-locking mechanism.

[0043] In this embodiment, a control box 5 can also be set on the fixed frame 1, and the first lead screw 2134 and the second lead screw 2143 can be connected to the control box 5, so that the first lead screw 2134 and the second lead screw 2143 can be controlled through the control box 5.

[0044] In this embodiment, the first mounting component 2131 and the third mounting component 2141 can be fixedly mounted on the fixed frame 1. The second mounting component 2132 and the fourth mounting component 2142 can be controlled by a cylinder or a hydraulic cylinder to ensure the limit of the paint material on the wire surface. The position control of the second mounting component 2132 and the fourth mounting component 2142 can be performed by the cylinder or the hydraulic cylinder through the control box 5.

[0045] The working process of this embodiment is as follows: When the size of the wire to be impregnated needs to be adjusted, the wire is first placed into the impregnation tank 2 through the inlet 217, and passes sequentially through the fourth adjusting frame 216, the first impregnation tank 211, the third adjusting frame 215, the second impregnation tank 212, the first adjusting frame 213, and the second adjusting frame 214, finally sliding out from the outlet 218. Next, the first lead screws 2134 on the first adjusting frame 213, the third adjusting frame 215, and the fourth adjusting frame 216 are adjusted so that both sides of the first and second paint film adjusting rollers 21311 and 21321 can contact the wire. Simultaneously, the second lead screw 2143 on the second adjusting frame 214 is adjusted so that both sides of the third and fourth paint film adjusting rollers 21411 and 21421 contact the wire. Finally, the movement of the wire is controlled by the wire feeding device and the wire take-up device to complete the impregnation process.

[0046] The wire feeding device and the wire take-up device are composed of a wire feeding roller and a wire take-up roller. Both the wire feeding device and the wire take-up device are existing technologies. This embodiment will not elaborate further.
