Description

Technical Field

[0001] This utility model relates to the field of keychain manufacturing technology, and in particular to a keychain steel ring bending device. Background Technology

[0002] Keychains are decorative items that are attached to key rings. Bending and shaping the steel ring is a crucial step in the manufacturing process of keychains. However, traditional keychain steel ring bending devices still have the following problems in use:

[0003] Traditional key ring bending devices mostly use manual operation or simple mechanical devices. These methods are not only inefficient, but also make it difficult to guarantee the accuracy and consistency of bending. At the same time, the bending mechanism of some existing equipment lacks flexibility and cannot adapt to the processing needs of key rings of different diameters, making it inconvenient to use.

[0004] To address the aforementioned problems, this utility model document proposes a keychain steel ring bending device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as low processing efficiency and lack of flexibility in the bending mechanism of traditional key ring bending devices, which make it difficult to adapt to the processing needs of steel rings of different specifications. Therefore, this invention proposes a key ring bending device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A keychain steel ring bending device, comprising:

[0008] The outer shell is divided into a drive chamber and a storage chamber by a partition. Three first rotating shafts are rotatably passed through one side of the drive chamber. The first rotating shaft in the middle is arranged horizontally and vertically with the remaining two first rotating shafts. The outer walls of the two first rotating shafts located on the same vertical line are slidably fitted with conveying wheels, and the outer wall of the other first rotating shaft is slidably fitted with a limiting wheel. The two conveying wheels are used to complete the conveying of the steel wire to be processed.

[0009] It also includes a support wheel and a pressing wheel, both of which are located outside the housing. The support wheel and the pressing wheel are used to press and bend the steel wire to be processed.

[0010] It also includes an adjustment component for adjusting the height of the support wheel and the extrusion wheel;

[0011] It also includes a first drive assembly, which is used to drive the rotation of the two conveying wheels and the limiting wheel;

[0012] It also includes a second drive assembly for driving the support wheel and the extrusion wheel to rotate.

[0013] In one possible design, the first drive assembly includes two connecting gears respectively fixedly sleeved on the outer walls of two first rotating shafts located on the same vertical line. Both connecting gears are located inside the housing and mesh with each other to achieve mutual opposite rotation of the two conveying wheels. Synchronous pulleys are fixedly sleeved on the outer walls of the two first rotating shafts located on the same horizontal line. Both synchronous pulleys are located inside the housing and are connected by the same synchronous belt. A first motor is fixedly installed on one inner wall of the drive chamber. One end of the output shaft of the first motor is fixedly connected to one end of one of the first rotating shafts to achieve simultaneous rotation of the limiting wheel and the two conveying wheels.

[0014] In one possible design, the adjustment assembly includes a first sliding chamber and a second sliding chamber fixedly penetrating one side of the drive chamber. The first and second sliding chambers have different heights. The interiors of both the first and second sliding chambers are connected to the outside. A first sliding block is slidably connected to the inner wall of the first sliding chamber, and a second sliding block is slidably connected to the inner wall of the second sliding chamber. A second rotating shaft rotatably penetrates the interior of both the first and second sliding blocks. The support wheel and the compression wheel are slidably sleeved on the outer wall of the corresponding second rotating shaft. A groove is provided on one side of both the first and second sliding chambers. One end of each of the two second rotating shafts passes through the corresponding groove and extends into the drive chamber. A first electric push rod is fixedly installed on the top of the first sliding chamber. One end of the piston rod of the first electric push rod slidably penetrates the top inner wall of the first sliding chamber and is fixedly connected to the top of the first sliding block. A second electric push rod is fixedly installed on the bottom of the second sliding chamber. One end of the piston rod of the second electric push rod slidably penetrates the bottom inner wall of the first sliding chamber and is fixedly connected to the bottom of the second sliding block.

[0015] In one possible design, the second drive assembly includes a rotating rod rotatably mounted on the inner wall of the bottom of the drive chamber. A second motor is fixedly mounted on the inner wall of the top of the drive chamber, and one end of the output shaft of the second motor is fixedly connected to the top of the rotating rod. Two sets of connecting mechanisms are externally connected to the rotating rod, and these two sets of connecting mechanisms are axially symmetrical. Each set of connecting mechanisms is used to drive the rotation of two second rotating shafts. Each connecting mechanism includes a mounting bracket sleeved on the outer wall of the rotating rod. The other side of the mounting bracket is rotatably sleeved on the outer wall of the corresponding second rotating shaft. A first bevel gear is slidably sleeved on the outer wall of the rotating rod, and the first bevel gear engages with the rotating rod through a groove. The first bevel gear is rotatably connected to the top of the mounting bracket. A second bevel gear is rotatably mounted on one side of the mounting bracket, and the first bevel gear meshes with the second bevel gear. A first gear is rotatably mounted on the other side of the mounting bracket. A second gear is fixedly sleeved on the outer wall of the corresponding second rotating shaft, and the first gear meshes with the second gear. The first gear and the second bevel gear are fixedly connected through a connecting shaft. The connecting mechanism is used to achieve the rotational drive of the second rotating shaft without affecting its vertical movement.

[0016] In one possible design, one end of each of the three first rotating shafts and the two second rotating shafts is threaded with a positioning nut, which is used to complete the installation and positioning between the corresponding wheel and the rotating shaft.

[0017] In one possible design, the storage compartment is equipped with multiple spare wheels of different diameters, which can be replaced as needed for processing.

[0018] In one possible design, a hinged door is attached to one side of the storage compartment, and a handle is fixedly installed on one side of the hinged door. The hinged door is used to ensure the safe storage of multiple spare wheels inside the storage compartment.

[0019] In this application, during use, the user can start the first motor and the second motor. Driven by the first motor, the two conveying wheels will rotate simultaneously and in opposite directions, ensuring a good conveying effect for the steel wire to be processed. The second motor can drive the rotating rod to rotate. When the rotating rod rotates, it can simultaneously drive the two second rotating shafts through two sets of connecting mechanisms. The two connecting mechanisms are axially symmetrical, and the two second rotating shafts rotate in opposite directions, ensuring continuous movement of the steel wire during bending. When the user places the steel wire to be processed between the two conveying wheels, the steel wire will be conveyed forward to the support wheel. Then the steel wire will abut against the outer wall of the extrusion wheel. Under the extrusion and support wheel, the steel wire will bend and continue to move forward, eventually forming a single loop or stacked loops. At this point, the user can remove and collect the processed key ring, and new steel wire can be inserted to allow for continuous processing. When users need to process keychain steel rings of different diameters, they only need to remove the corresponding positioning nuts while the machine is stopped, remove the support wheel, and select a spare wheel of the appropriate size for installation. Simultaneously, the user needs to activate the first and second electric push rods to push the corresponding first and second sliding blocks, causing them to move the corresponding second rotating shaft. This ensures that the edge of the new support wheel mates with the conveyor wheel and limit wheel, and also moves the extrusion wheel to a position that mates with the new support wheel. Afterward, processing resumes. Due to the change in the diameter of the support wheel, the degree of bending of the steel wire during processing will also change. Once processing is complete, a keychain steel ring of the new specification will be obtained. After replacing the wheel, the user should store the unused wheel in the storage room. After processing is finished, the movable door can be closed to ensure the safe storage of the spare wheel and prevent damage or loss.

[0020] Beneficial effects: In this utility model, the key ring bending device achieves stable and efficient conveying of the steel wire to be processed by setting two conveying wheels that rotate in opposite directions and a limiting wheel; the cooperative design of the conveying wheels and the limiting wheel ensures that the steel wire will not get stuck or deviate from the track during the conveying and processing, thus improving the accuracy and reliability of key ring conveying and processing.

[0021] In this utility model, the key ring bending device, through the design of the adjustment component, realizes the up and down adjustment of the support wheel and the extrusion wheel, so as to adapt to the processing needs of key rings of different diameters; users only need to replace the support wheel and the extrusion wheel of the appropriate size and adjust the position of the support wheel and the extrusion wheel accordingly to easily complete the processing of key rings of different specifications.

[0022] In this utility model, the key ring bending device automatically drives the conveying wheel, limiting wheel, support wheel, and extrusion wheel by setting a first driving component and a second driving component. The user only needs to start the motor, and the device can automatically complete the conveying and bending of the steel wire, which greatly improves production efficiency and automation. At the same time, the device has a compact structure and reasonable connection between the components, which improves the stability and reliability of the device, facilitates the adjustment and maintenance of the device, and reduces the difficulty and cost of operation.

[0023] In this utility model, the key ring bending device, by setting up a storage chamber and a movable door, enables convenient access and safe storage of spare wheels. Users can store unused wheels in the storage chamber, and close the movable door after processing, which allows for easy access to spare wheels at any time and also avoids damage or loss of spare wheels. This design not only improves the practicality and ease of operation of the device, but also extends the service life of the spare wheels.

[0024] In this invention, the keychain steel ring bending device, through the cooperation of a counter-rotating conveyor wheel and a limiting wheel, ensures stable and efficient feeding of steel wire, improving processing accuracy. The adjustable component design allows the support wheel and extrusion wheel to be adjusted up and down, and can be used with different specification rotating wheels to meet the processing needs of steel rings of different specifications. The device simplifies the operation process through the drive component, improving production efficiency and device stability. The storage chamber and movable door design facilitate the safe storage and easy access of spare rotating wheels, enhancing practicality. The overall design is efficient, flexible, and easy to use, significantly improving the production efficiency and product quality of keychain steel rings. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1: Refer to Figure 1-7 A bending device, comprising:

[0035] The outer casing 1 is internally divided into a drive chamber 7 and a storage chamber 8 by a partition. Three first rotating shafts 9 rotatably pass through one side of the drive chamber 7, with the middle shaft 9 arranged horizontally and vertically with the remaining two shafts 9. Conveyor wheels 2 are slidably fitted onto the outer walls of the two shafts 9 on the same vertical line for conveying the steel wire to be processed. A limiting wheel 3 is slidably fitted onto the outer wall of the other shaft 9 to limit the movement of the steel wire in conjunction with the conveyor wheel 2.

[0036] To achieve the bending of the steel wire, this embodiment also includes a support wheel 4 and a pressing wheel 5 located outside the outer casing 1. The support wheel 4 and the pressing wheel 5 work together to press and bend the steel wire to be processed.

[0037] In order to adjust the height of the support wheel 4 and the extrusion wheel 5 to accommodate the bending requirements of steel wires of different diameters, this embodiment also includes an adjustment component.

[0038] In order to drive the conveyor wheel 2 and the limit wheel 3 to rotate, this embodiment also includes a first drive component.

[0039] To drive the rotation of the support wheel 4 and the extrusion wheel 5, this embodiment also includes a second drive assembly.

[0040] Furthermore, in this embodiment, the first drive assembly includes two connecting gears 10 disposed within the drive chamber 7. Each connecting gear 10 is fixedly sleeved on the outer wall of two first rotating shafts 9 located on the same vertical line. The two connecting gears 10 mesh with each other to achieve opposite rotation of the two conveying wheels 2. Simultaneously, synchronous pulleys 11 are fixedly sleeved on the outer walls of the two first rotating shafts 9 located on the same horizontal line, and the two synchronous pulleys 11 are connected by a synchronous belt drive. A first motor 12 is fixedly installed on one inner wall of the drive chamber 7, and one end of the output shaft of the first motor 12 is fixedly connected to one end of one of the first rotating shafts 9. When the first motor 12 starts, it can drive the limiting wheel 3 and the two conveying wheels 2 to rotate simultaneously.

[0041] Further, in this embodiment, the adjustment assembly includes a first sliding chamber 13 and a second sliding chamber 14 fixedly penetrating one side of the drive chamber 7, and the two are at different heights. The interiors of both the first sliding chamber 13 and the second sliding chamber 14 are connected to the outside, and a first sliding block 20 and a second sliding block 21 are slidably connected to them respectively. A second rotating shaft 22 rotatably penetrates the interior of both the first sliding block 20 and the second sliding block 21, and the support wheel 4 and the extrusion wheel 5 are slidably fitted onto the outer wall of the corresponding second rotating shaft 22. A groove 15 is provided on one side of both the first sliding chamber 13 and the second sliding chamber 14, and one end of each of the two second rotating shafts 22 passes through the corresponding groove 15 and extends into the drive chamber 7. A first electric push rod 16 is fixedly installed on the top of the first sliding chamber 13, and one end of its piston rod is fixedly connected to the top of the first sliding block 20. A second electric push rod 17 is fixedly installed on the bottom of the second sliding chamber 14, and one end of its piston rod is fixedly connected to the bottom of the second sliding block 21. The heights of the support wheel 4 and the extrusion wheel 5 can be adjusted respectively by extending and retracting the first electric push rod 16 and the second electric push rod 17.

[0042] Further, in this embodiment, the second drive assembly includes a rotating rod 18 rotatably mounted on the bottom inner wall of the drive chamber 7, and a second motor 19 fixedly mounted on the top inner wall of the drive chamber 7. One end of the output shaft of the second motor 19 is fixedly connected to the top end of the rotating rod 18. Two sets of connecting mechanisms are externally connected to the rotating rod 18. Each set of connecting mechanisms includes a mounting bracket 24 sleeved on the outer wall of the rotating rod 18, and the other side of the mounting bracket 24 rotatably sleeved on the outer wall of the corresponding second rotating shaft 22. A first bevel gear 25 is slidably sleeved on the outer wall of the rotating rod 18. The first bevel gear 25 engages with the rotating rod 18 through a groove and is rotatably connected to the top of the mounting bracket 24. A second bevel gear 26 is rotatably mounted on one side of the mounting bracket 24, and the first bevel gear 25 meshes with the second bevel gear 26. A first gear 27 is rotatably mounted on the other side of the mounting bracket 24, and a second gear 28 is fixedly sleeved on the outer wall of the corresponding second rotating shaft 22, and the first gear 27 meshes with the second gear 28. The first gear 27 and the second bevel gear 26 are fixedly connected by a connecting shaft. When the second motor 19 is started, it can drive the support wheel 4 and the pressing wheel 5 to rotate. Due to the design of the connecting mechanism, the rotation of the second rotating shaft 22 can be driven without affecting its up-and-down movement. At the same time, the two sets of connecting mechanisms are axially symmetrical, which can ensure that the rotating rod 18 can simultaneously drive the two second rotating shafts 22 to rotate in opposite directions.

[0043] This application can be used in the field of keychain manufacturing technology, or in other fields applicable to this application.

[0044] Example 2: Reference Figure 1 , 2 5, 7, Improvements based on Example 1: A key ring bending device, which is applied to the field of key ring production technology;

[0045] To ensure a secure connection between the rotating wheels and the rotating shafts, in this embodiment, one end of each of the three first rotating shafts 9 and the two second rotating shafts 22 is threaded with a positioning nut 23. The design of the positioning nut 23 also allows for easy disassembly of the multiple rotating wheels, facilitating subsequent replacement or maintenance as needed.

[0046] In this embodiment, the storage compartment 8 is equipped with multiple spare rollers of different diameters, which can be replaced as needed for processing. When the diameter of the support roller 4 used by the equipment changes, the size and specifications of the key ring produced will also change accordingly, thus meeting the processing requirements for key rings of different specifications.

[0047] In this embodiment, a movable door 6 is hinged to one side of the storage compartment 8, and a handle is fixedly installed on one side of the movable door 6 to ensure the safe storage of multiple spare wheels in the storage compartment 8.

[0048] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 12, the first electric push rod 16, the second electric push rod 17, and the second motor 19 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0049] The working principle and usage process of this technical solution are as follows: During use, the user can start the first motor 12 and the second motor 19. Driven by the first motor 12, the two conveying wheels 2 will rotate simultaneously and in opposite directions, ensuring a good conveying effect for the steel wire to be processed. The second motor 19 can drive the rotating rod 18 to rotate. When the rotating rod 18 rotates, it can simultaneously drive the two second rotating shafts 22 through two sets of connecting mechanisms. The two connecting mechanisms are axially symmetrical, and the two second rotating shafts 22 rotate in opposite directions, ensuring continuous movement of the steel wire during bending. When the user places the steel wire to be processed between the two conveying wheels 2, the steel wire will be conveyed forward to the support wheel 4. Then, the steel wire will abut against the outer wall of the extrusion wheel 5. Under the extrusion of the extrusion wheel 5 and the support wheel 4, the steel wire bends and continues to move forward. Simultaneously, with the cooperation of the limiting wheel 3, the entire steel wire can eventually form a single loop or stacked loops. At this point, the user can remove and collect the processed keychain steel ring, and new steel wire can be inserted to allow for continuous processing. When users need to process key rings of different diameters, they only need to remove the corresponding positioning nut 23 while the machine is stopped, remove the support wheel 4, and select a spare wheel of appropriate size for installation (the extrusion wheel 5 can also be replaced accordingly depending on the actual situation). At the same time, users need to start the first electric push rod 16 and the second electric push rod 17 to push the corresponding first sliding block 20 and the second sliding block 21, so that they drive the corresponding second rotating shaft 22 to move, ensuring that the edge of the new support wheel 4 can cooperate with the conveying wheel 2 and the limiting wheel 3. At the same time, the extrusion wheel 5 also needs to be moved to the position that cooperates with the new support wheel 4. After that, processing starts again. Since the diameter of the support wheel 4 has changed, the degree of bending of the steel wire to be processed will also change during processing. As processing is completed, a key ring of the new specification can be obtained. After replacing the wheel, the user should store the unused wheel in the storage room 8. After processing is completed, the movable door 6 can be closed to ensure the safe storage of the spare wheel and prevent damage or loss.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
