Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to an adjustable tape winding device for a small transformer. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). In electrical equipment and wireless circuits, it is commonly used for voltage step-up / step-down, impedance matching, and safety isolation.

[0003] Before leaving the factory, transformers typically need to have insulating tape wrapped around their outer perimeter to make the core more secure, improve the core stacking accuracy, and make the joints between the cores better, thereby reducing iron loss and noise. At the same time, it can also increase the protection and insulation between the core and the coil, as well as the coil itself, and improve the insulation withstand voltage performance of the product.

[0004] With the development of the times and the advancement of technology, transformer coating devices also have significant shortcomings. They cannot meet the requirements of transformer coating, and the coating devices cannot be adjusted in structure, and can only coat power transformers of the same size. Therefore, an adjustable tape wrapping device for small transformers is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address existing problems by providing an adjustable tape winding device for small transformers.

[0006] This utility model is achieved through the following technical solution: an adjustable tape winding device for a small transformer, comprising a base frame, a roller for supporting the tape roll rotatably mounted at one end of the base frame, one end of the roller being rotatably connected to a wall plate, the wall plate being vertically connected to the base frame, a pin assembly being mounted at the other end of the roller, a pressure rod being mounted on the outside of the roller, the lower end of the pressure rod being rotatably connected to an end frame, the end frame being connected to the end of the base frame, a spindle being rotatably mounted at the other end of the base frame, one end of the spindle being rotatably connected to a wall plate, the end of the spindle being connected to the output shaft of a low-speed motor, and the other end of the spindle being connected to a support on the base frame via an adjustable mechanism.

[0007] As a further improvement to the above solution, the pin assembly includes a rod body, which is inserted into an outer waist hole. The outer waist holes are symmetrically arranged at the roller end away from the wall panel. The rod body is connected to the roller by a bolt, and the bolt passes through an inner waist hole, which is located on the rod body. The bolt presses the rod body against the roller through a pressure ring.

[0008] The rod is fixed by the pressure ring on the bolt. When the pressure ring is detached from the rod, the rod can rotate horizontally within the outer waist hole, so that the tape can be rolled onto the roller.

[0009] As a further improvement to the above solution, the axis of the rod and the bolt are perpendicular to each other and intersect on the axis of the drum.

[0010] The rod is fixed and limited by a bolt, which ensures that the rod can effectively block the tape roll on the roller and prevent the tape roll from falling off the roller. At the same time, rotating the rod makes it easier for the tape roll to be put on the roller.

[0011] As a further improvement to the above solution, the adjustable mechanism includes a roller, which is rotatably disposed on the lower side of the spindle end away from the second wall panel. The roller is rotatably connected to the upper end of the wheel frame, and the lower end of the wheel frame is rotatably connected to the bottom frame. The working rod end of the cylinder is hinged on the wheel frame, and the cylinder is rotatably mounted on the bottom frame.

[0012] The cylinder drives the wheel frame to rotate inward into the base frame, causing the roller to disengage from the outer end of the spindle, making it easier to mount and remove the transformer coil from the spindle.

[0013] As a further improvement to the above solution, a baffle is provided on the bottom frame, and the baffle is vertically arranged on the outside of the wheel frame;

[0014] The rotation of the wheel frame is restricted by the baffle to prevent it from rotating outwards from the bottom frame, ensuring that the wheel frame can effectively support the outer end of the spindle when it rotates directly below the spindle.

[0015] As a further improvement to the above solution, both the outer sides of wall panel one and wall panel two are supported by corner plates to strengthen the structural support of wall panel one and wall panel two and prevent them from tilting.

[0016] As a further improvement to the above solution, a retaining ring is provided at the end of the roller near the first wall panel to block and limit the tape roll mounted on the roller, so as to prevent the tape roll from rubbing against the first wall panel during the tape release and rotation process.

[0017] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. The tape roll is mounted on the roller and fixed and limited by the pin assembly to ensure that the tape roll is stably mounted on the roller. In addition, the mandrel driven by a low-speed motor rotates to wrap the coil mounted on the mandrel with tape. Furthermore, the mandrel is supported by an adjustable mechanism to ensure the balance of the mandrel under the load of the coil and to avoid deformation and damage to the mandrel. The adjustable mechanism is rotated by a cylinder to facilitate the mounting and removal of the coil. Attached Figure Description

[0020] Figure 3 This is a schematic diagram of the installation structure of the pin assembly. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 3 As shown, an adjustable tape winding device for a small transformer includes a base frame 1. One end of the base frame 1 is rotatably equipped with a roller 2 for supporting the tape roll. One end of the roller 2 is rotatably connected to a wall panel 3, which is vertically connected to the base frame 1. The other end of the roller 2 is equipped with a pin assembly 4. A pressure rod 6 is provided on the outside of the roller 2. The lower end of the pressure rod 6 is rotatably connected to an end frame 7, which is connected to the end of the base frame 1. The other end of the base frame 1 is rotatably equipped with a spindle 8. One end of the spindle 8 is rotatably connected to a wall panel 9, and the end of the spindle 8 is connected to the output shaft of a low-speed motor 10, which is mounted on the wall panel 9. The other end of the spindle 8 is connected to a component supported on the base frame 1 by an adjustable mechanism.

[0023] As a further improvement to the above solution, the pin assembly 4 includes a rod body 42, which is inserted into an outer waist hole 41. The outer waist hole 41 is symmetrically arranged at the end of the roller 2 away from the wall panel 3. The rod body 42 is connected to the roller 2 by a bolt 45, and the bolt 45 passes through an inner waist hole 43, which is arranged on the rod body 42. The bolt 45 presses the rod body 42 against the roller 2 by a pressure ring 44.

[0024] The rod body 42 is fixed by the pressure ring 44 on the bolt 45. The pressure ring 44 is detached from the rod body 42, and the rod body 42 can rotate horizontally in the outer waist hole 41 so that the tape can be rolled onto the roller 2.

[0025] As a further improvement to the above scheme, the axis lines of the rod 42 and the bolt 45 are perpendicular to each other and intersect on the axis line of the roller 2.

[0026] The rod 42 is fixed and limited by the bolt 45, so that the rod 42 can effectively block the tape roll on the roller 2 and prevent the tape roll from falling off the roller 2. At the same time, rotating the rod 42 makes it easier for the tape roll to be put on the roller 2.

[0027] As a further improvement to the above solution, the adjustable mechanism includes a roller 12, which is rotatably disposed on the lower side of the end of the spindle 8 away from the wall panel 2 9. The roller 12 is rotatably connected to the upper end of the wheel frame 13, and the lower end of the wheel frame 13 is rotatably connected to the bottom frame 1. The working rod end of the cylinder 14 is hinged to the wheel frame 13, and the cylinder 14 is rotatably mounted on the bottom frame 1.

[0028] The cylinder 14 drives the wheel frame 13 to rotate inward into the base frame 1, causing the roller 12 to disengage from the outer end of the spindle 8, making it easier to mount and remove the transformer coil from the spindle 8.

[0029] As a further improvement to the above solution, a baffle 15 is provided on the bottom frame 1, and the baffle 15 is vertically arranged on the outside of the wheel frame 13;

[0030] The rotation of the wheel frame 13 is restricted by the baffle 15 to prevent the wheel frame 13 from rotating outward from the bottom frame 1, so that the wheel frame 13 can effectively support the outer end of the spindle 8 when it rotates to the point directly below the spindle 8.

[0031] As a further improvement to the above solution, the outer sides of both wall panel 3 and wall panel 9 are supported by corner plates 11 to strengthen the structural support of wall panel 3 and wall panel 9 and prevent them from tilting.

[0032] As a further improvement to the above solution, a retaining ring 5 is provided at the end of the roller 2 near the wall panel 3 to block and limit the tape roll mounted on the roller 2, so as to prevent the tape roll from rubbing against the wall panel 3 during the tape release and rotation process.

[0033] The working principle of an adjustable tape winding device for a small transformer is as follows: a tape roll is mounted on a roller 2, and a pin assembly is used to fix and limit the tape roll, ensuring that the tape roll is securely mounted on the roller 2. In addition, the mandrel 8 driven by a low-speed motor 10 rotates to wrap the coil mounted on the mandrel 8 with tape. The mandrel 8 is supported by an adjustable mechanism to ensure the balance of the mandrel 8 under the load of the coil, avoiding deformation and damage to the mandrel 8. The adjustable mechanism is rotated by a cylinder 14 to facilitate the mounting and removal of the coil.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
