Description

Technical Field

[0001] This utility model belongs to the technical field of adhesive application equipment, and in particular relates to an adhesive paper application mechanism for the magnetic leakage sheet of a microwave oven transformer. Background Technology

[0002] The core heating element of a microwave oven is the magnetron, which requires thousands of volts of high-voltage direct current to operate. The microwave oven transformer (usually called a high-voltage transformer) is this key component. It steps up the household AC mains power (such as 220V) to the high voltage required by the magnetron (usually above 2000V), while providing a lower voltage (such as 3.3V) to heat the magnetron filament. The core of the transformer is made of laminated silicon steel sheets (i.e., magnetic leakage sheets), the purpose of which is to form a magnetic circuit, guide and concentrate the magnetic flux, and carry out efficient electromagnetic energy conversion. During the manufacturing process, the surface of the transformer magnetic leakage sheets needs to be covered with adhesive paper.

[0003] In existing technologies, the magnetic leakage sheet lacks effective fixation during the rotating adhesive application process, making it prone to displacement or wobbling. This results in inaccurate adhesive application. Furthermore, traditional manual adhesive application or mechanical pressing methods often result in uneven pressure, leading to air bubbles, wrinkles, or localized delamination, which affects insulation performance. Therefore, we provide a magnetic leakage sheet adhesive application mechanism for microwave oven transformers to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a mechanism for applying adhesive paper to the magnetic leakage sheet of a microwave oven transformer. By moving the positioning block, the stability of the transformer magnetic leakage sheet during the adhesive application process can be ensured. At the same time, the cylinder pushes the U-shaped plate to move, thereby improving the adhesion strength between the adhesive paper and the transformer magnetic leakage sheet during the adhesive application process.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a mechanism for applying adhesive paper to the magnetic leakage sheet of a microwave oven transformer, comprising a processing plate; an assembly plate is provided on the left side of the front of the processing plate, and a rotating disk is bolted to the rear end face of the assembly plate; a positioning disk is provided on the right side of the front of the processing plate, symmetrically arranged with the rotating disk; an inner threaded ring is provided on the front of the positioning disk; multiple storage openings are provided on the outer side wall of the positioning disk in a ring evenly distributed along the circumference, and positioning blocks are provided inside each storage opening; a cylinder is bolted to the front end face of the processing plate directly above the positioning disk; a U-shaped plate is fixed to the piston end of the cylinder; and a pulley is rotatably arranged on the inner side wall of the U-shaped plate.

[0006] The present invention is further configured such that a baffle is fixed to the rear end face of the rotating disk, and a shaft rod is fixed to the middle position of the rear end face of the baffle and rotatably connected to the processing plate through a bearing.

[0007] The present invention is further configured such that a base plate is fixed to the lower end face of the processing plate, and a reinforcing plate is fixed at the connection between the rear end face of the processing plate and the upper end face of the base plate.

[0008] The present invention is further configured such that a screw rod that is helically connected to the inner threaded ring is fixed in the middle of the front end face of the positioning disk, and a movable ring plate that is sleeved on the screw rod is provided on the rear end face of the inner threaded ring.

[0009] The present invention is further configured such that the inner end face of the storage port is provided with a curved hole that penetrates the front end face of the positioning plate, and multiple rubber rods are fixed on the rear end face of the moving ring plate, which are respectively inserted into the inside of the curved hole. Each rubber rod is fixed with a vertical rod that is bolted to the positioning block at the end face of the curved hole.

[0010] The present invention is further configured such that a T-shaped opening is provided on the rear end face of the inner threaded ring, and an annular T-plate is fixed on the front end face of the movable ring plate to be used in rotational cooperation with the T-shaped opening.

[0011] The present invention is further configured such that a circular plate is fixed to the rear end face of the positioning plate, a rotating shaft is fixed to the rear end face of the circular plate and rotatably connected to the processing plate via a bearing, and a motor is fixed to the rear end face of the processing plate and driven by the rotating shaft.

[0012] This utility model has the following beneficial effects: This invention places the transformer leakage magnetic sheet on the positioning plate and controls the inner threaded ring to move towards the positioning plate on the screw. The inner threaded ring controls the positioning block to move outward in the receiving opening, thereby controlling the positioning block to abut against the inner wall of the transformer leakage magnetic sheet. Thus, multiple sets of positioning blocks control the position of the transformer leakage magnetic sheet to remain stationary, achieving stability of the transformer leakage magnetic sheet during the adhesive application process.

[0013] This invention controls the operation of a cylinder, which in turn moves a U-shaped plate toward a positioning disc. This causes the pulleys on the inner side of the U-shaped plate to press the adhesive paper firmly against the surface of the transformer's magnetic leakage sheet. Therefore, when the transformer's magnetic leakage sheet is winding up the adhesive paper, the pulleys used increase the strength of the adhesive paper's adhesion to the surface of the transformer's magnetic leakage sheet.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0024] Please see Figures 1 to 7 This utility model is a mechanism for applying adhesive paper to the magnetic leakage sheet of a microwave oven transformer. By moving the positioning block 606, the stability of the transformer magnetic leakage sheet during the adhesive application process can be ensured. At the same time, the cylinder 4 pushes the U-shaped plate 401 to move, thereby improving the adhesion strength between the adhesive paper and the transformer magnetic leakage sheet during the adhesive application process.

[0025] Specifically, processing plate 1; assembly plate 2 is provided on the left side of the front of processing plate 1, and a rotating disk 201 is bolted to the rear end face of assembly plate 2. A positioning disk 3 is provided on the right side of the front of processing plate 1, symmetrically arranged with rotating disk 201. An inner threaded ring 6 is provided on the front of positioning disk 3. Multiple storage openings 305 are evenly distributed in a ring along the circumference of the outer side wall of positioning disk 3. Positioning blocks 606 are provided inside each storage opening 305. A cylinder 4 is bolted to the front end face of processing plate 1 directly above positioning disk 3. A U-shaped plate 401 is fixed to the piston end of cylinder 4. A pulley 402 is rotatably arranged on the inner side wall of U-shaped plate 401. A circular plate 301 is fixed to the rear end face of positioning disk 3. A rotating shaft 302 is fixed to the rear end face of circular plate 301 and rotatably connected to processing plate 1 through a bearing. A motor 5 is fixed to the rear end face of processing plate 1 and is drivenly connected to rotating shaft 302.

[0026] The operation process of this embodiment is as follows: Using the above-described structure, the transformer leakage magnetic sheet is directly fitted onto the positioning disk 3, and the inner threaded ring 6 is rotated. This rotates the positioning block 606 to press against the inner wall of the transformer leakage magnetic sheet. Then, the adhesive tape roll is fitted onto the rotating disk 201, and one end of the adhesive tape roll is manually attached to the surface of the transformer leakage magnetic sheet. The motor 5 is then controlled to operate, causing the motor 5 to rotate the rotating shaft 302, the circular plate 301, and the positioning disk 3. This causes the transformer leakage magnetic sheet to tear the adhesive tape under the adhesive tape roll. The adhesive tape roll drives the rotating disk 201 to rotate. After the adhesive tape is applied to the transformer magnetic leakage sheet, the adhesive tape is cut off by an external shearing device. When the adhesive tape is applied to the surface of the transformer magnetic leakage sheet, the control cylinder 4 is activated. The cylinder 4 drives the U-shaped plate 401 to move towards the positioning disk 3, so that the pulley 402 on the inner side of the U-shaped plate 401 presses the adhesive tape firmly to the surface of the transformer magnetic leakage sheet. Therefore, when the transformer magnetic leakage sheet rewinds the adhesive tape, the pulley 402 increases the strength of the adhesive tape adhering to the surface of the transformer magnetic leakage sheet. Example

[0027] Please see Figure 1 , Figure 2 and Figure 7 Based on Example 1, the use of baffle 202 prevents the adhesive tape roll from shifting.

[0028] Specifically, a baffle 202 is fixed to the rear end face of the rotary disk 201, and a shaft 203 is fixed to the middle position of the rear end face of the baffle 202 and rotatably connected to the processing plate 1 via a bearing. A base plate 101 is fixed to the lower end face of the processing plate 1, and a reinforcing plate 102 is fixed at the connection between the rear end face of the processing plate 1 and the upper end face of the base plate 101.

[0029] The operation process of this embodiment is as follows: When the rotating disk 201 rotates, it will drive the shaft 203 to rotate on the processing plate 1. At the same time, the base plate 101 and the reinforcing plate 102 are used to support the processing plate 1, so as to ensure that the structure on the processing plate 1 can be stable during operation. Meanwhile, when the adhesive tape roll is put on the rotating disk 201, the baffle 202 limits the adhesive tape roll to prevent the adhesive tape roll from deviating. Example

[0030] Please see Figure 4 and Figure 5 Based on Example 1, the use of the inner screw ring 6 and the movable ring plate 602 together ensures easy control of the movement of the moving block.

[0031] Specifically, a screw 303 is fixed in the middle of the front end face of the positioning disk 3 and is helically connected to the inner threaded ring 6. A movable ring plate 602 is provided on the rear end face of the inner threaded ring 6 and is sleeved on the screw 303. The inner end face of the receiving port 305 is provided with a bent hole 304 that penetrates the front end face of the positioning disk 3. Multiple rubber rods 604 are fixed on the rear end face of the movable ring plate 602 and are respectively inserted into the inside of the bent hole 304. Vertical rods 605 that are bolted to the positioning block 606 are fixed on the end face of the rubber rods 604 at the bent hole 304. A T-shaped ring opening 601 is provided on the rear end face of the inner threaded ring 6. An annular T-plate 603 that is rotatably engaged with the T-shaped ring opening 601 is fixed on the front end face of the movable ring plate 602.

[0032] The operation process of this embodiment is as follows: When it is necessary to control the positioning block 606 to move out of the receiving port 305, the inner threaded ring 6 can be controlled to rotate on the screw 303, so that the inner threaded ring 6 will move towards the positioning disk 3, and then the inner threaded ring 6 will push the moving ring plate 602, so that the moving ring plate 602 controls the rubber rod 604 to bend and move in the bending hole 304, thereby pushing the vertical rod 605 to push the positioning block 606 out of the receiving port 305. When the inner threaded ring 6 rotates, the inner threaded ring 6 rotates along the annular T plate 603 through the T-shaped ring opening 601, so that the inner threaded ring 6 will not drive the moving ring plate 602 to rotate when it rotates. And through the threaded engagement between the inner threaded ring 6 and the screw 303, the inner threaded ring 6 can be stably positioned when it is not rotating, thereby ensuring that the positioning block 606 will not move arbitrarily.
