Description

Technical Field

[0001] This utility model relates to the field of electrical equipment manufacturing, specifically to a drying device for insulating varnish. Background Technology

[0002] Insulating varnish is widely used in the manufacturing process of electrical equipment. It forms an insulating protective layer on the conductor surface of electrical equipment, effectively improving its electrical insulation performance, preventing faults such as leakage and short circuits, and thus ensuring stable equipment operation and user safety. However, the key to achieving optimal performance of insulating varnish lies in the drying process.

[0003] In existing technologies, the heating method is singular and the temperature cannot be precisely controlled, resulting in uneven drying. Some insulating varnishes may have their performance affected by excessively high or low temperatures. At the same time, the lack of an effective internal structure for fixing the items makes it easy for the insulating varnish items to shift during the drying process, further reducing the drying quality. In view of this, we propose a novel drying device for insulating varnish to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a drying device for insulating varnish, thus solving the problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for insulating varnish, comprising a drying chamber, a push handle fixedly provided on the left side wall of the drying chamber, locking casters provided at the four corners of the bottom of the drying chamber, a sealing door movably connected to the front of the drying chamber via a screw, an mounting plate fixedly connected to the right side wall of the drying chamber, a drying mechanism provided on the mounting plate, and a limiting mechanism fixedly installed in the inner cavity of the drying chamber.

[0006] Preferably, the drying mechanism includes a fan mounted on a mounting plate, the air inlet of the fan is connected to a tank, a tank temperature sensor is fixedly installed on the top of the tank, an electric heating tube is bolted to the inner wall of the tank, and a fixed cover is bolted to the front of the electric heating tube.

[0007] Specifically, this design uses a fan to draw outside air into the tank, where heating elements on the inner wall heat the air. A tank temperature sensor monitors the air temperature in real time, allowing for precise control of the heating power of the heating elements to ensure a constant output hot air temperature. A fixing cover secures the heating elements, ensuring structural stability and safe, stable operation during heating. This provides a stable and suitable temperature of hot air into the drying oven, improving the drying effect.

[0008] Preferably, the drying mechanism further includes an air outlet pipe, the output end of the fan is connected to the air outlet pipe, the output end of the air outlet pipe is connected to a flexible hose, a cylinder is installed through the top of the drying box, the telescopic end of the cylinder is connected to a movable plate, the top of the flexible hose is connected to the movable plate, a plurality of drying pipes are connected to the bottom of the movable plate, and a nozzle is connected to the bottom of the drying pipes.

[0009] Specifically, in this design, the hot air output by the fan is delivered to the movable plate via an air outlet pipe and flexible hose. Multiple drying pipes and nozzles at the bottom of the movable plate evenly spray the hot air onto the insulating varnish items inside the drying chamber, achieving all-round and uniform drying. The cylinder can move the movable plate up and down, and the nozzle position can be flexibly adjusted according to the different heights of the insulating varnish items, making the drying device suitable for drying various sizes of items, greatly improving the versatility and applicability of the device.

[0010] Preferably, the limiting mechanism includes a support plate, a hollow groove is provided through the surface of the support plate, a worm is connected in the hollow groove through a bearing ring, a fixing plate is fixed at the bottom of the support plate, a motor is installed on the side wall of the fixing plate, a worm wheel is connected to the output shaft of the motor, the worm wheel is meshed with the worm, and clamping plates are sleeved on both sides of the outer wall of the worm.

[0011] Specifically, this design uses a motor to drive a worm gear, which meshes with the worm, causing the worm to rotate. This, in turn, moves the clamping plates fitted on both sides of the worm's outer wall relative to each other. In this way, the clamping plates can clamp and secure the insulating varnish items placed on the support plate. This limiting mechanism effectively prevents displacement of the items during the drying process due to uneven heating, ensuring uniform heating of all parts of the items and improving drying quality.

[0012] Preferably, the front of the sealed door is provided with an observation window;

[0013] Specifically, this design features an observation window on the front of the sealed door, allowing operators to observe the drying status of the insulating varnish items inside the drying oven in real time without opening the sealed door.

[0014] Preferably, the inner sidewall of the clamp is provided with a buffer pad, the buffer pad is made of rubber and its surface is provided with anti-slip texture, and a miniature pressure sensor is installed on the clamp.

[0015] Specifically, the rubber cushioning pads on the inner walls of the clamps prevent direct contact between the clamps and items with insulating paint, thus avoiding damage. The rubber material itself has elasticity, allowing it to adapt to items of different shapes. The anti-slip texture on the surface of the cushioning pads increases friction with the items, making them more stable under the clamps and preventing them from sliding during the drying process due to vibration or other factors, ensuring a smooth drying process.

[0016] Preferably, a sealing strip is provided at the contact point between the sealing door and the drying oven, and the sealing strip is made of a high-temperature resistant and aging-resistant material;

[0017] Specifically, the high-temperature resistant and aging-resistant sealing strips at the contact points between the sealing door and the drying oven effectively fill the gaps between the sealing door and the drying oven, preventing heat loss during the drying process, maintaining a high-temperature environment inside the oven, and reducing energy consumption.

[0018] Preferably, a controller is provided on one side wall of the drying oven, and the signal end of the miniature pressure sensor is connected to the input end of the controller. Beneficial effects

[0019] This invention provides a drying device for insulating varnish. Compared with the prior art, it has the following advantages:

[0020] 1. The blower, in conjunction with the tank, heating element, and tank temperature sensor, heats the air to a suitable temperature before delivering it into the drying chamber. The heating element heats the air inside the tank, while the tank temperature sensor monitors the temperature in real time, allowing for timely adjustments to the heating power and ensuring a stable output hot air temperature. The blower delivers the heated air through an outlet pipe and hose to the movable plate, and then through multiple drying pipes and nozzles to evenly spray it onto the insulating varnish items inside the drying chamber, ensuring uniform heating and improving drying effect and efficiency. A cylinder moves the movable plate up and down, allowing the nozzle position to be adjusted according to the height of the items being dried, increasing the versatility of the drying device.

[0021] 2. The motor drives the worm gear to rotate, which meshes with the worm, causing the worm to rotate as well. The clamping plates on both sides of the worm's outer wall can move relative to each other as the worm rotates, thus clamping and securing the insulating varnish items placed on the support plate. The rubber buffer pads on the inner walls of the clamping plates not only prevent damage to the items during clamping, but their anti-slip texture further increases friction, ensuring the items are firmly fixed and preventing movement during drying, which would affect the drying effect.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: a drying device for insulating varnish, including a drying box 1, characterized in that: a pusher 5 is fixedly provided on the left side wall of the drying box 1, locking casters 7 are provided at the four corners of the bottom of the drying box 1, a sealing door 6 is movably connected to the front of the drying box 1 through a screw, an mounting plate 2 is fixedly connected to the right side wall of the drying box 1, a drying mechanism 3 is provided on the mounting plate 2, and a limiting mechanism 8 is fixedly installed in the inner cavity of the drying box 1.

[0029] The drying mechanism 3 includes a fan 305, which is mounted on the mounting plate 2. The air inlet of the fan 305 is connected to a tank 303. A tank temperature sensor 304 is fixedly installed on the top of the tank 303. An electric heating tube 302 is bolted to the inner wall of the tank 303. A fixing cover 301 is bolted to the front of the electric heating tube.

[0030] The drying mechanism 3 also includes an air outlet pipe 306. The output end of the fan 305 is connected to the air outlet pipe 306, and the output end of the air outlet pipe 306 is connected to a flexible hose 307. A cylinder 308 is installed through the top of the drying box 1. The telescopic end of the cylinder 308 is connected to a movable plate 309. The top of the flexible hose 307 is connected to the movable plate 309. Multiple drying pipes 310 are connected to the bottom of the movable plate 309, and nozzles 311 are connected to the bottom of the drying pipes 310.

[0031] The limiting mechanism 8 includes a support plate 801, a hollow groove 802 extending through the surface of the support plate 801, a worm gear 803 connected to the hollow groove 802 via a bearing ring, a fixing plate fixed to the bottom of the support plate 801, a motor 804 mounted on the side wall of the fixing plate, a worm wheel 805 connected to the output shaft of the motor 804, the worm wheel 805 meshing with the worm gear 803, and clamping plates 806 sleeved on both sides of the outer wall of the worm gear 803.

[0032] Among them, the front of the sealed door 6 is provided with an observation window.

[0033] Among them, the inner wall of the clamping plate 806 is provided with a buffer pad, which is made of rubber and has anti-slip texture on its surface. A miniature pressure sensor 807 is installed on the clamping plate 806.

[0034] Among them, the contact area between the sealing door 6 and the drying oven 1 is equipped with a sealing strip, which is made of a high-temperature resistant and aging-resistant material.

[0035] Among them: a controller 4 is installed on one side wall of the drying oven 1, and the signal end of the miniature pressure sensor 807 is connected to the input end of the controller 4.

[0036] The working principle of the above embodiment is as follows: The workpiece that needs to be dried with insulating varnish is placed on the limiting mechanism 8 inside the drying chamber 1. By pushing the pusher 5 on the left side wall of the drying chamber 1, the four corner locking casters 7 at the bottom are used to move the drying chamber to a suitable working position and lock the casters to fix the drying chamber. The sealing door 6 is opened and connected by a screw to place the workpiece on the support plate 801 of the limiting mechanism 8. At this time, the motor 804 is started. The output shaft of the motor 804 drives the worm gear 805 to rotate. Since the worm gear 805 is meshed with the worm 803, the worm 803 rotates, and the clamping plates 806 on both sides of the outer wall of the worm 803 will move inward. When the clamping plate 806 contacts the item, the miniature pressure sensor 807 installed on the clamping plate 806 starts to detect the clamping force and transmits the signal to the controller 4 in real time. When the pressure signal received by the controller 4 reaches the preset threshold, the controller 4 automatically cuts off the power to the motor 804, so that the clamping plate 806 stops moving, thereby achieving precise clamping and avoiding damage to the item due to over-clamping. Meanwhile, the rubber buffer pads and anti-slip textures on the inner wall of the clamping plate 806 further protect the items and increase friction. The rubber buffer pads with anti-slip textures on the inner wall of the clamping plate 806 clamp the workpiece, serving a limiting and fixing function. The sealing door 6 is closed. Because the contact area between the sealing door 6 and the drying oven 1 is equipped with high-temperature resistant and aging-resistant sealing strips, the sealing of the drying oven 1 is ensured. The controller 4 on one side wall of the drying oven 1 is operated to start the drying mechanism 3. A power interface is provided on the side of the fixed cover 301. It is connected to the wiring terminal of the heating element 302 via a wire. The heating element 302 starts working, heating the air inside the tank 303. The tank temperature sensor 304 monitors the temperature inside the tank 303 in real time and feeds the temperature data back to the controller 4 for temperature control. The fan 305 starts. When hot air is supplied into the chamber through the drying pipe 310 and nozzle 311, the hot air rises inside the chamber and can be discharged through the ventilation holes at the top, forming natural thermal convection, which helps to improve drying efficiency. The heated air in the tank 303 is drawn in through the air inlet, enters the air outlet 306 through the output end of the fan 305, and is then delivered to the movable plate 309 through the hose 307. The cylinder 308 is activated, and its telescopic end drives the movable plate 309 to move up and down, causing the multiple drying pipes 310 and nozzles 311 connected to the bottom of the movable plate 309 to move up and down, so that the hot air can be evenly sprayed on the workpiece to dry the insulating varnish. During the drying process, the drying status of the workpiece in the drying chamber 1 can be observed through the observation window on the front of the sealed door 6. When the insulating varnish is dried, the controller 4 is turned off, stopping the operation of the drying mechanism 3 and the limit mechanism 8. The sealed door 6 is opened, and the motor 804 is started to reverse, causing the clamping plate 806 to move outward to release the workpiece and remove the dried workpiece.
