Multiple limit baffles are evenly spaced on the conveyor belt. An automatic feeding hopper is installed at one end of the stainless steel support, and a product receiving box is installed at the other end. A demagnetizing device is mounted on the stainless steel support, comprising an open-circuit demagnetizing coil, an intelligent control circuit, a PLC control circuit, a heat-dissipating aluminum plate, a cooling fan, and a limit steel plate. A height adjustment device is installed between the demagnetizing device and the stainless steel support. A workpiece sensor is installed at the front end of the limit steel plate. This utility model has a simple structure, is easy to operate, and can work continuously for more than 4 hours, greatly extending the continuous working time of the demagnetizing device. It can automatically demagnetize parts, simplifying the demagnetizing process and improving efficiency. It also solves the safety hazards caused by operator negligence or prolonged absence and saves energy.

[0004] The device claimed in this patent extends the continuous working time of the demagnetizing device and improves efficiency. However, existing devices cannot clamp and fix the coil during use, which causes the coil to shake during demagnetization, thus affecting the demagnetization effect. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing devices cannot clamp and fix the coil during use, which causes the coil to shake during demagnetization and thus affects the demagnetization effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a large-diameter 304 stainless steel demagnetizing coil device, comprising a conveyor belt, a clamping assembly connected to the surface of the conveyor belt, the clamping assembly comprising a support frame, two sets of electric push rods connected to the top of the support frame, the output ends of the two sets of electric push rods connected to the main body of the demagnetizing device, a fixed frame connected to the bottom surface of the conveyor belt, a bidirectional screw inserted into the interior of the fixed frame, slots opened on both sides of the fixed frame, a motor connected to the bottom of the fixed frame, a first gear connected to the output end of the motor, a second gear connected to the surface of the bidirectional screw, a movable frame connected inside the slots, guide rods connected to the inner sides of both sets of movable frames, clamps connected to the interior of the guide rods by bolts, and guide holes opened on both sides of the support frame.

[0007] Furthermore, the two sets of electric push rods are controlled by the same set of control switches, and the output end of the motor is fixedly connected to the first gear.

[0008] Furthermore, the outer surface of the guide rod is in contact with the inner wall of the guide hole, and a sliding connection is formed between the guide rod and the guide hole.

[0009] Furthermore, the movable frame and the bidirectional screw are connected by a thread, and the first gear and the second gear are connected by a meshing connection.

[0010] Furthermore, the rear end of the conveyor belt is connected to a material discharge protection component, which includes a material discharge frame. The surface of the material discharge frame is provided with a placement platform, and grooves are opened on the top of both sides of the placement platform.

[0011] Furthermore, the upper end of the chute is connected to a collection box, and the bottom of the collection box is connected to a slider.

[0012] Furthermore, slots are formed inside the four corners of the placement platform, and springs are installed inside the slots, with the bottom of the springs connected to the top block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when demagnetizing a large-diameter 304 stainless steel coil, the coil to be demagnetized can be placed on the surface of a conveyor belt and transported by the conveyor belt. After moving to the bottom of the main body of the demagnetizing device, the double-headed screw can be driven to rotate by turning on the motor. Then, the two sets of clamps can clamp and fix the coil by rotating the screw thread. Finally, the demagnetizing process is carried out by the main body of the demagnetizing device.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, such as Figure 1 - Figure 4As shown, this utility model provides a large-diameter 304 stainless steel demagnetizing coil device, including a conveyor belt 1, a clamping assembly 2 connected to the surface of the conveyor belt 1, the clamping assembly 2 including a support frame 201, two sets of electric push rods 202 connected to the top of the support frame 201, the output ends of the two sets of electric push rods 202 connected to the demagnetizing device body 203, a fixing frame 205 connected to the bottom surface of the conveyor belt 1, a bidirectional screw 208 inserted into the inside of the fixing frame 205, slots 210 opened on both sides of the fixing frame 205, a motor 206 connected to the bottom of the fixing frame 205, a first gear 207 connected to the output end of the motor 206, and a second gear 207 connected to the surface of the bidirectional screw 208. 09. The slot 210 is internally connected to a movable frame 211. The inner sides of both movable frames 211 are connected to guide rods 212. The guide rods 212 are internally connected to clamps 213 by bolts. The support frame 201 has guide holes 204 on both sides. The two sets of electric push rods 202 are the same set of control switches. The output end of the motor 206 is fixedly connected to the first gear 207. The outer surface of the guide rod 212 is in contact with the inner wall of the guide hole 204. The guide rod 212 and the guide hole 204 are slidably connected. The movable frame 211 is threadedly connected to the bidirectional screw 208. The first gear 207 and the second gear 209 are meshed.

[0025] The overall effect of Embodiment 1 is that, when demagnetizing a large-diameter 304 stainless steel coil, the coil to be demagnetized can be placed on the conveyor belt 1 and transported by the conveyor belt 1. When the coil enters the bottom position of the demagnetizing device body 203, the conveyor belt 1 is turned off. Then, the forward rotation function of the motor 206 can be started by the control switch, so that the output end of the motor 206 can drive the first gear 207 to rotate forward and mesh with the second gear 209 in the forward direction, thereby enabling the bidirectional screw 208 to rotate forward. When the bidirectional screw 208 rotates forward, it will simultaneously rotate in the forward thread with the two sets of moving frames 211, thereby achieving the effect of rotation through the thread. The two sets of moving frames 211 move inward simultaneously, thereby driving the clamps 213 to clamp and fix the coil. Then, the electric push rod 202 can be activated to push the demagnetizing device body 203 downward, thus demagnetizing the coil. After demagnetization, the electric push rod 202 will drive the demagnetizing device body 203 to retract upward. At this time, the reverse rotation function of the motor 206 is activated, causing the two sets of moving frames 211 to move to both sides simultaneously through reverse screw rotation, thereby driving the two sets of clamps 213 to move outward simultaneously, no longer clamping the coil. The conveyor belt 1 is then set up so that the conveyor belt 1 can carry the demagnetized coil into the collection box 304.

[0026] Example 2, as Figure 1 and Figure 5As shown, the rear end of the conveyor belt 1 is connected to the unloading protection component 3. The unloading protection component 3 includes an unloading rack 301. The surface of the unloading rack 301 is provided with a placement platform 302. The top of both sides of the placement platform 302 is provided with a sliding groove 303. The upper end of the sliding groove 303 is connected to a collection box 304. The bottom of the collection box 304 is connected to a slider 305. The four corners of the placement platform 302 are provided with slots 306. Springs 307 are provided inside the slots 306. The bottom of the springs 307 is connected to a top block 308.

[0027] The effect achieved by the entire embodiment 2 is that when the workpiece enters the collection box 304, the collection box 304 will cause the spring 307 and the top block 308 to be squeezed by pressing downward. Through the elastic structure, the impact force when the workpiece falls is reduced, effectively protecting the workpiece. After the workpiece is stationary, the spring 307 releases its stored energy to push the top block 308 to reset, maintaining the gap between the workpieces in the box and avoiding damage from stacking and squeezing. When a large number of workpieces are collected in the collection box 304, the collection box 304 can be pulled outward, so that the slider 305 at the bottom of the collection box 304 can slide out from the groove 303, which is convenient and quick.

[0028] Working principle: When demagnetizing a large-diameter 304 stainless steel coil, the coil to be demagnetized can be placed on the surface of the conveyor belt 1 and transported by the conveyor belt 1. After moving to the bottom of the demagnetizing device body 203, the double-acting screw 208 can be rotated by turning on the motor 206. The two sets of clamps 213 can clamp and fix the coil through the screw rotation. Finally, the demagnetizing process is completed by the demagnetizing device body 203. This avoids the problem of existing devices being unable to clamp and fix the coil during demagnetization, and improves the stability of the coil during demagnetization. After demagnetization, the 304 stainless steel coil will enter the collection box 304 for collection. Under the elastic action of the top block 308 and the spring 307, the impact force when the workpiece enters the collection box 304 can be reduced, thus protecting the workpiece.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
