Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and in particular to a rotor packaging device. Background Art

[0002] The rotor is the rotating part of the motor. After being processed and oiled, if the rotors are directly stacked, the anti-rust oil on the rotors will drip into the external environment, causing environmental pollution. Furthermore, if the rotors are exposed to air for a long time, the anti-rust oil on the rotor surface will gradually fall off, causing direct contact and reaction between the rotors and water molecules in the air, resulting in corrosion and affecting the subsequent use of the rotors.

[0003] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0004] In order to prevent the rotor from being directly exposed to the air and rusting after production, the present application provides a rotor packaging device.

[0005] This application provides a rotor packaging device, which adopts the following technical solution:

[0006] A rotor packaging device comprises a conveying track for conveying the rotor, a heat pressing assembly arranged on the conveying track for closing a film, and an unwinding roller for unwinding a film roll;

[0007] The conveying track includes a base and a belt conveying device arranged on the base;

[0008] The heat pressing assembly is arranged above the base, and includes a mounting frame arranged on the base, two heat pressing wheels slidably arranged in the mounting frame, and a heat pressing drive member that pushes the two heat pressing wheels to move horizontally. The two heat pressing wheels close the two side walls of the film wrapped around the rotor and heat press them together.

[0009] The unwinding roller is arranged below the base, and the film on the unwinding roller moves along the upper end surface of the belt conveyor device.

[0010] By adopting the above technical solution, the processed rotor is packaged with a film so that the rotor will not be directly exposed to the outside air, thereby reducing the probability of the rotor rusting and making the subsequent use of the rotor less likely to be affected.

[0011] Optional: The base is also provided with a heat-splitting assembly for separating the film that has been heat-pressed. The heat-splitting assembly includes two heat-pressing blocks for cutting and sealing the film and a splitting drive for driving the heat-pressing blocks to move vertically. The two heat-pressing blocks move vertically and clamp the film. The heat-pressing blocks are used to separate and seal the film between adjacent rotors.

[0012] By adopting the above technical solution, the films between adjacent rotors are cut and pressed together, so that a single rotor and the film form an independent entity, thereby making the transfer of the rotors more convenient.

[0013] Optionally: A limit assembly for limiting the position of the rotor is also provided on the base, and the limit assembly is provided on the side of the heat separation assembly away from the heat pressing assembly. The limit assembly includes two limit plates provided on the base and limit driving members for respectively pushing the two limit plates to move horizontally. The two limit plates are provided on both sides of the rotor and can jointly clamp the rotor along the side wall.

[0014] By adopting the above technical solution, during hot segmentation, the position of the rotor on one side of the hot pressing plate is limited by the limiting assembly, so that the size of the film covering the rotor is not too small, and the film can stably cover the rotor.

[0015] Optionally, the limiting plate is arranged in an arc shape, and the circle of the limiting plate coincides with the axis of the rotor.

[0016] By adopting the above technical solution, the limiting plate is made to fit the shape of the rotor more closely, so that the limiting plate can stably clamp the rotor.

[0017] Optionally, a buffer is provided on the side wall of the limiting plate close to the rotor, and the buffer can abut against the rotor.

[0018] By adopting the above technical solution, the buffer member can be more closely fitted to the surface of the rotor, making the positioning of the rotor more stable.

[0019] Optional: The base is also provided with a blocking assembly for limiting the stopping position of the rotor, the blocking assembly includes two side walls arranged on the base, a guide plate arranged at one end of the side plate close to the heat separation assembly and an anti-slip plate for blocking the movement of the rotor, the side plates are respectively arranged on both sides of the belt conveyor, the anti-slip plate is arranged at the end of the side plate away from the heat separation assembly, and the guide plates are away from each other at the end away from the side plate.

[0020] By adopting the above technical solution, when the rotor is not removed from the belt conveyor in time, the blocking assembly can be used to block the movement of the rotor, so that the rotor is not likely to fall from the base.

[0021] Optionally: A flattening piece is also provided on the base, and the flattening piece is provided on the side of the heat separation component close to the heat pressing component and above the rotor, and the lower end of the flattening piece can abut and slide against the upper end of the rotor provided in the film.

[0022] By adopting the above technical solution, the position of the rotor located on the other side of the thermal cutting assembly is limited, so that the length of the film covering the rotor is not easily too short.

[0023] Optional: Two guide plates for guiding the shape of the film are provided at one end of the base for inputting the film, and the guide plates are respectively provided on both sides of the belt conveyor device. A guide slope is provided at one end of the guide plate away from the hot pressing assembly, and the upper end of the guide slope is inclined toward the direction of the hot pressing assembly.

[0024] By adopting the above technical solution, when the film is transferred from the unwinding roller to the belt conveyor, the film can be formed into a U-shape with the opening upward by utilizing the guide plate, thereby making it more convenient to package the rotor with the film.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] The present application discloses a rotor packaging device, such as Figure 1 As shown, the apparatus comprises a conveyor track 1 for conveying the rotor, a heat-compression bonding assembly 2 disposed on the conveyor track 1 for closing the film, and an unwinding roller 3 for unwinding the film. The conveyor track 1 comprises a base 11 disposed on the ground, and a belt conveyor 12 disposed on the base 11. The base 11 is also provided with two horizontal baffles 13, which are disposed on either side of the belt conveyor 12 to ensure that the rotor can be stably conveyed on the belt conveyor 12.

[0034] like Figure 2 As shown, two sets of heat-pressing assemblies 2 are arranged along the conveying direction of the belt conveyor 12. Both sets of heat-pressing assemblies 2 are installed on the base 11 and are located above the belt conveyor 12. The heat-pressing assemblies 2 include a mounting frame 21 mounted on the base 11, two heat-pressing rollers 22 slidably mounted within the mounting frame 21, and a heat-pressing drive 23 that drives the two heat-pressing rollers 22 horizontally. The mounting frame 21 is arranged with an opening at the bottom. The heat-pressing rollers 22 and the heat-pressing drive 23 are both mounted at the bottom opening of the mounting frame 21. In this embodiment, the heat-pressing drive 23 is a pneumatic cylinder. The heat-pressing drive 23 is horizontally mounted within the mounting frame 21. An induction block 24 is also mounted on the driving end of the heat-pressing drive 23. The heat-pressing rollers 22 are rotatably connected to the bottom of the induction block 24. Under the drive of the heat-pressing drive 23, the two heat-pressing rollers 22 approach each other, clamping and heat-pressing the two side walls of the film, thereby forming a tubular structure for accommodating the rotor. The hot pressing wheel 22 is heated by electromagnetic heating. An induction heating element is provided inside the hot pressing wheel 22, and an electromagnetic induction coil is provided inside the induction block 24. When powered on, the electromagnetic induction coil heats the induction heating element, thereby increasing the temperature of the hot pressing wheel 22 and hot pressing the film.

[0035] like Figure 1As shown, the unwinding roller 3 is positioned below the base 11, near the end of the belt conveyor 12 that receives the rotor. After unwinding, the film on the unwinding roller 3 moves along the upper end of the belt conveyor 12, with the rotor positioned above the film on the belt conveyor 12. The base 11 is also equipped with two guide plates 31 to guide the film's shape. These guide plates 31 are positioned on either side of the belt conveyor 12, near the end of the belt conveyor 12 that receives the rotor. A horizontal plate is secured to the lower ends of the two guide plates 31, whose upper ends are flush with the upper end of the belt conveyor 12. A guide slope 311 is provided on the ends of the two guide plates 31 facing away from the thermal bonding assembly 2. The upper ends of the guide slopes 311 are angled toward the thermal bonding assembly 2. As the film moves from below onto the belt conveyor 12, it adheres to the guide slopes 311, forming a U-shaped shape with its opening facing upward. This allows the rotor to be positioned directly within the opening formed by the film, facilitating subsequent thermal bonding.

[0036] like Figure 3 As shown, when the film is heat-pressed by the heat-pressing assembly 2, the film can only form a tubular structure, so that multiple rotors are all located in the same space, which is inconvenient for the subsequent transportation of the rotors. Therefore, a heat-splitting assembly 4 is also provided on the base 11 to separate the film after heat pressing. The heat-splitting assembly 4 includes two heat-pressing blocks 41 for cutting and sealing the film and a splitting drive 42 for driving the heat-pressing blocks 41 to move vertically. The splitting drive 42 is a cylinder in this embodiment. A gantry 43 is provided at the upper end of the base 11. A heat-pressing block 41 slides vertically in the gantry 43. A splitting drive 42 is installed on the gantry 43. The driving end of the splitting drive 42 is connected to the upper end of the heat-pressing block 41, thereby driving the heat-pressing block 41 to move back and forth. Another hot pressing block 41 slides vertically on the base 11, and another segmentation drive member 42 is mounted on the base 11. The driving end of the segmentation drive member 42 located below is fixed to the lower end surface of the hot pressing block 41 located below, thereby driving the two hot pressing blocks 41 to move in opposite directions. A resistance wire is provided inside the hot pressing block 41. When the resistance wire is heated by electricity, the hot pressing block 41 is heated. The two hot pressing blocks 41 abut against each other, so that the hot pressing blocks 41 can melt the film between the adjacent rotors and heat-press the film at the melted position.

[0037] During heat separation, the film is subjected to a force directed toward the heat press block 41. Consequently, the rotor located on the side of the heat separation assembly 4 away from the heat pressing assembly 2 is subjected to pressure and moves toward the heat separation assembly 4. This can result in the film on the rotor being too short to fully cover the rotor. Therefore, the base 11 is also provided with a limit assembly 5 for limiting the rotor's position. The limit assembly 5 comprises two limit plates 51 slidably disposed on the base 11 and a limit drive 52 that respectively pushes the two limit plates 51. In this embodiment, the limit drive 52 is a pneumatic cylinder. The two limit plates 51 are arranged parallel to the conveying direction of the belt conveyor 12. The two limit plates 51 are disposed on either side of the belt conveyor 12 and are located on the side of the heat separation assembly 4 away from the heat pressing assembly 2. The two limit drives 52 are both mounted on the base 11. The drive ends of the two limit drives 52 are connected to the limit plates 51, thereby driving the two limit plates 51 toward each other and clamping the rotor, thereby maintaining the rotor's position during the heat separation process.

[0038] like Figure 1 As shown, in order to keep the position of the rotor on the side where the thermal cutting assembly is away from the limiting assembly 5 stable, a flattening member 7 is further provided on the base 11. The flattening member 7 is provided above the rotor transported by the belt conveyor 12. The flattening member 7 includes a flattening frame 71 provided on the base 11, a plurality of rotating rollers 72 rotatably connected to the flattening frame 71, and a flattening belt 73 sleeved on the rotating rollers 72. The lower end of the flattening belt 73 abuts against the top of the rotor, so that the position of the rotor can be limited.

[0039] like Figure 3 As shown, in order to enable the limiting plates 51 to stably clamp the rotor, the limiting plates 51 are arranged in an arc shape, and the arc axis of the limiting plates 51 is parallel to the axis of the rotor. Buffers 53 are provided on the side walls of the two limiting plates 51 that are close to each other. The buffers 53 are sponge pads in this embodiment. The buffers 53 can abut against the rotor, thereby stably clamping the rotor.

[0040] Due to the continuous conveying of the rotor, if the rotor at the end of the belt conveyor 12 is not removed in time, it may fall to the ground, causing damage to the rotor. Therefore, the base 11 is also provided with a blocking assembly 6 that defines the stopping position of the rotor. The blocking assembly 6 includes two side plates 61 disposed on the base 11, a guide plate 62 disposed on the end of the side plate 61 near the heat splitter assembly 4, and a stop plate to prevent the movement of the rotor. The two side plates 61 are respectively disposed on either side of the belt conveyor 12. The ends of the two guide plates 62 away from the side plates 61 are separated from each other, forming a flared opening, allowing the rotor to stably enter between the two side plates 61 as it moves along the belt conveyor 12. The stop plate 63 is disposed on the end of the side plate 61 away from the heat splitter assembly 4 and is fixed to the base 11. The stop plate abuts the two side plates 61. If the rotor is not removed from the belt conveyor 12 in time, the movement of the rotor can be restricted by the stop plate, preventing the rotor from being pushed off the base 11.

[0041] The implementation principle of this embodiment is: the rotor is placed on the film on the belt conveyor 12, and the film moves under the conveyance of the belt conveyor 12. Then, the film forms an upper-opening structure driven by the guide plate 31, and then the hot pressing wheel 22 brings the two sides of the film close to each other for hot pressing. Then, it continues to be transported to the bottom of the hot cutting assembly, and the hot pressing blocks 41 of the hot cutting assembly approach each other to cut and press the film between adjacent rotors. During pressing, the limit plates 51 approach each other to clamp the rotor, thereby completing the packaging of one rotor.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
