Description

Technical Field

[0001] This utility model belongs to the field of microwave oven manufacturing technology, and in particular relates to a microwave oven transformer leakage magnetic sheet insulating paper cutting mechanism. Background Technology

[0002] A microwave oven is a modern cooking appliance that heats food using microwaves. The magnetic leakage sheet and insulating paper in a microwave oven transformer are two key components that play a crucial role in the transformer's performance, efficiency, and safety. The magnetic leakage sheet is a special magnetic guiding structure in microwave oven transformers (especially high-voltage transformers), typically made of stacked silicon steel sheets and intentionally installed on non-main magnetic flux paths in the magnetic circuit. Its core function is not to enhance the efficiency of main magnetic flux transmission, but to guide and utilize "leakage flux." Insulating paper is inserted between the stacked magnetic leakage sheets and between the coil and the iron core. The insulating paper cutting mechanism is an automated or semi-automated device specifically designed to precisely cut the insulating material before or during the assembly of the transformer core (iron core), ensuring the production efficiency and precision of the insulating paper.

[0003] A search revealed that publication number CN114229577B, filed on December 16, 2021, discloses a fully automatic lead wire sleeve manufacturing machine, which sequentially includes a feeding mechanism, a pressing mechanism, a film cutting mechanism, a driving mechanism, an insulating paper cutting mechanism, an adhesive application mechanism, and a winding mechanism. The feeding mechanism provides a film and insulating paper, which pass through the aforementioned mechanisms in sequence and are finally wound into a sleeve by the winding mechanism. The pressing mechanism presses the film and insulating paper together and can release them. The film cutting mechanism separates the film and insulating paper and cuts the film after they have moved forward a predetermined distance. The driving mechanism presses the film and insulating paper together and drives them to move. The insulating paper cutting mechanism cuts the insulating paper after the cut end of the film passes through it.

[0004] However, it still has the following drawbacks in practical use: The existing microwave oven transformer leakage magnetic sheet insulation paper cutting mechanism can only cut the insulation paper in one direction during use. This method cannot cut the insulation paper in both length and width at the same time, resulting in low efficiency and limited applicability. 2. Existing microwave oven transformer magnetic leakage sheet insulation paper cutting mechanisms require multiple drive devices to operate multiple cutters, resulting in high equipment costs. Therefore, we provide a microwave oven transformer magnetic leakage sheet insulation paper cutting mechanism to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0027] Please see Figures 1 to 3This utility model is a microwave oven transformer leakage magnetic sheet insulation paper cutting mechanism, including a body 100 and a support rod 101 installed at one end of its front end. A vertical cutting component 300 is provided on the other side of the front end of the body 100, and a horizontal cutting component 400 is provided in front of the front end of the body 100. The vertical cutting component 300 includes an upper sealing cylinder 301 and a lower sealing cylinder 302 installed above and below one side of the front end of the body 100. A cutter 303 is slidably installed inside the upper sealing cylinder 301 and the lower sealing cylinder 302. A telescopic rod 304 is installed at both the front and rear ends inside the upper sealing cylinder 301. The horizontal cutting component 400 includes a fixing plate 401 installed on one side of the upper sealing cylinder 301. A sliding groove 401a is provided at both the front and rear ends of the bottom of the fixing plate 401. A second movable frame 404 is installed inside the sliding groove 401a.

[0028] Specifically, a tension spring 304a is sleeved on the outer wall of the telescopic rod 304. The two ends of the tension spring 304a are fixed to the inner wall of the upper sealing cylinder 301 and the adjacent cutter 303, respectively. The air pipes of both the upper sealing cylinder 301 and the lower sealing cylinder 302 are connected to the first connecting pipe 305 via pipe joints. The other end of the first connecting pipe 305 is connected to the second connecting pipe 306a via a pipe joint. The other end of the second connecting pipe 306a is connected to the air pipe on the air cylinder 306 via a pipe joint. A piston rod 306b is slidably installed inside the air cylinder 306. The top end of the piston rod 306b is movably connected to the movable rod 307a via a hinge. The top end of the movable rod 307a is rotatably mounted on the rear end face of the disc 307. A rotating shaft 308 is fixed at the center of the front end face of the disc 307. The front end of 308 passes through the bearing on the fixed frame 309 and is connected to the first driven gear 308a. The top end of the fixed frame 309 is fixed to the bottom of the slide frame 205. The center positions of the two side walls of the slide groove 401a are each embedded with a second electromagnetic block 401b. The front and rear ends of the bottom of the fixed plate 401 are respectively fixed with a first side plate 402 and a second side plate 403. The top of the second moving frame 404 is embedded with a second iron block 404a. The bottom of the second moving frame 404 is rotatably mounted with a spline sleeve 404b. The spline sleeve 404b is slidably inserted into the inside of the spline sleeve 404b. The front end of the second spline shaft 405 is rotatably mounted in the bearing on the first side plate 402. The rear end of the second spline shaft 405 passes through the bearing on the second side plate 403 and is connected to the second driven gear 405a.

[0029] Furthermore, the upper sealing cylinder 301 and the lower sealing cylinder 302 are symmetrically arranged. After the cutter 303 in the lower sealing cylinder 302 is lifted by air pressure, it can fall down under its own gravity. The telescopic rod 304 plays a limiting and guiding role on the tension spring 304a. Under the elastic action of the tension spring 304a, the cutter 303 in the upper sealing cylinder 301 can be pulled upward. The pipe joint plays the role of pipe connection. The two ends of the movable rod 307a are respectively rotatably installed on the surface of the disc 307 and the top of the piston rod 306b. Therefore, when the disc 307 rotates, the piston rod 306b moves up and down reciprocally under the action of the movable rod 307a. Under the magnetic force of the second electromagnetic block 401b and the second iron block 404a, the position of the second moving frame 404 can be adjusted, thereby adjusting the distance between the two saw blades.

[0030] The operation process of this embodiment is as follows: When it is necessary to cut the insulating paper, the motor 201 is started. The output shaft of the motor 201 rotates, driving the transmission shaft 202 to rotate through the coupling. The rotation of the transmission shaft 202, under the action of the first spline shaft 203a and the spline groove, drives the moving shaft 203 and the active gear disk 203b on its outer wall to rotate synchronously. The active gear disk 203b meshes with the first driven gear disk 308a and the second driven gear disk 405a, so the rotation of the active gear disk 203b will drive the first driven gear disk 308a and the second driven gear disk 405a to rotate synchronously. The rotation of the first driven gear disk 308a drives the disk 307 to rotate through the rotating shaft 308. The two ends of the movable rod 307a are respectively rotatably mounted on the surface of the disk 307 and one end of the piston rod 306b. The rotation of the disk 307 will drive the piston rod 306b to reciprocate up and down through the movable rod 307a. The reciprocating compression of the air cylinder 306 causes the gas in the air cylinder 306 to enter the upper sealing cylinder 301 and the lower sealing cylinder 302 through the first connecting pipe 305 and the second connecting pipe 306a. The increased air pressure in the upper sealing cylinder 301 and the lower sealing cylinder 302 pushes the corresponding cutter 303 out to cut the insulating paper into segments. At the same time, the rotation of the second driven toothed disc 405a will cause the second spline shaft 405 and the spline sleeve 404b and the saw blade on its outer wall to rotate. The rotating saw blade can cut the edge of the insulating paper, which can trim the width of the insulating paper. Under the magnetic force of the second electromagnetic block 401b and the second iron block 404a, the position of the second moving frame 404 at both ends can be adjusted, and the distance between the front and rear saw blades can be adjusted as needed. Therefore, it is possible to control the length of the insulating paper and trim its width. The length and width of the insulating paper can be cut at the same time, and the work efficiency is high. Example

[0031] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6Based on Embodiment 1, unlike the first embodiment, a drive assembly 200 is provided. The drive assembly 200 includes a motor 201 mounted on the front end face of the body 100, and a transmission shaft 202 mounted on the output shaft of the motor 201 via a coupling. A movable shaft 203 is provided at the front end of the transmission shaft 202, and a first spline shaft 203a is fixed at the center of the rear end face of the movable shaft 203. This solves the problem that the existing microwave oven transformer leakage magnetic sheet insulation paper cutting mechanism requires multiple drive devices to drive multiple cutters, resulting in high equipment costs.

[0032] Specifically, the first splined shaft 203a is slidably inserted into the spline groove on the transmission shaft 202, the movable shaft 203 is rotatably installed inside the first movable frame 204, and the middle of the outer wall of the movable shaft 203 is fitted with an active gear 203b; the first iron block 204a is embedded inside the first movable frame 204, the first movable frame 204 is slidably installed inside the slide frame 205, and the center of the two groove walls of the slide frame 205 is embedded with a first electromagnetic block 205a, and the rear end face of the slide frame 205 is installed on the front end face of the body 100.

[0033] Furthermore, the drive shaft 202 and the moving shaft 203 are connected by a first spline shaft 203a and a spline groove. Under the magnetic force of the first electromagnetic block 205a and the first iron block 204a, the position of the first moving frame 204 can be adjusted to adjust the position of the drive gear 203b, so that the drive gear 203b can mesh or disengage with the first driven gear 308a and the second driven gear 405a.

[0034] The operation process of this embodiment is as follows: When the first electromagnetic block 205a at the front end or rear end is energized, a magnetic attraction is generated between the first electromagnetic block 205a and the first iron block 204a, so the first moving frame 204 can slide inside the sliding frame 205, and achieve the purpose of adjusting the position of the moving shaft 203 and the active gear disk 203b, so that the active gear disk 203b can contact and mesh with the first driven gear disk 308a and the second driven gear disk 405a individually, or contact and mesh with the first driven gear disk 308a and the second driven gear disk 405a simultaneously, thereby realizing that the cutter 303 and the saw blade can operate individually or simultaneously. The length and width cutting operation of the insulating paper can be completed by a single motor 201, which is low in cost.
