Description

Technical Field

[0001] This utility model relates to the field of keychain technology, specifically to an O-chain keychain forming machine. Background Technology

[0002] An O-chain keychain is a chain consisting of an O-shaped chain and a key ring. It is commonly used to make various ornaments or handicrafts, such as necklaces, bracelets, and pendants. The O-chain is a string of interconnected metal or plastic rings, while the key ring is a metal or plastic ring that can be opened and closed for hanging various items.

[0003] Currently, O-chain keychains on the market are often made manually, meaning the O-chain is first hooked onto the key ring by hand to form the keychain. This method has the following disadvantages:

[0004] Manual operation is inefficient and slow, and cannot meet market demand.

[0005] Manual operation results in inconsistent quality and is prone to defects such as chain breakage, misalignment, and scratches.

[0006] Manual labor is physically demanding and can easily cause fatigue and injury to workers.

[0007] High manual operation costs increase production expenses. Utility Model Content

[0008] The purpose of this utility model is to solve the above-mentioned technical problems, thereby providing an O-chain keychain forming machine;

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0010] This utility model provides an O-chain keychain forming machine.

[0011] The device includes a base frame, an O-chain forming mechanism, a conveying mechanism, a flipping mechanism, a dropping mechanism, and a mounting frame. The conveying mechanism is located on the upper surface of the base frame, the mounting frame is located on one side of the conveying mechanism, the O-chain forming mechanism is located on the mounting frame, the flipping mechanism is located on one side of the O-chain forming mechanism, and the dropping mechanism is located at the lower end of the mounting frame. The O-chain forming mechanism is used to form an O-chain, the conveying mechanism is used to convey key rings, the flipping mechanism first grabs the key ring conveyed by the conveying mechanism, the flipping mechanism drives the key ring to rotate above the O-chain forming mechanism, and hooks the formed O-chain, thereby forming an O-chain keychain, which is then conveyed and collected by the dropping mechanism.

[0012] Optionally, the O-chain forming mechanism includes a spiral forming machine, a cutting mechanism, and a rotating mechanism. The spiral forming machine includes a motor, a transmission shaft, a first gear, a second gear, a bevel gear, a connecting shaft, a connecting rod, a rack, a rotating shaft, a third gear, a forming plate, and a forming wheel. The motor is mounted on the base frame, and the transmission shaft is connected to the output shaft of the motor. The first gear and the second gear are both mounted on the transmission shaft. The bevel gear is mounted on the connecting shaft and meshes with the second gear. The connecting shaft is connected to one end of the rack via a connecting rod. The rotating shaft has the third gear mounted on it, and the rack is positioned below the third gear and meshes with the third gear. The motor drives the transmission shaft, the first gear, and the second gear to rotate, thereby driving the bevel gear and the connecting shaft to rotate. The connecting shaft drives the connecting rod to move left and right, which in turn drives the rack to move left and right, thereby driving the rotating shaft to rotate. The rotating shaft is used to convey iron wire. A template is positioned on one side of the output end of the rotating shaft, and a forming wheel is positioned on the forming template. The forming wheel is used to form straight steel wires into annular O-rings. A cutting mechanism is used to cut the annular O-rings. A rotating mechanism is used to grab the cut annular O-rings and rotate them. The opening of the annular O-rings faces the output end of the rotating shaft. The forming wheel sequentially forms several sets of annular O-rings. The cutting mechanism sequentially cuts several sets of annular O-rings one by one. The rotating mechanism grabs several sets of annular O-rings one by one to form an O-chain. When the rotating mechanism grabs the next set of annular O-rings, the opening of the annular O-ring on the rotating mechanism faces the next set of annular O-rings. During the grabbing process, the opening of the annular O-ring on the rotating mechanism is fitted onto the side wall of the next set of annular O-rings. After the grabbing is completed, the rotating mechanism rotates again, so that the opening of the second grabbed annular O-ring faces the output end of the rotating shaft. This process is repeated to form the O-chain.

[0013] Optionally, the flipping mechanism includes a first rotating gear, a second rotating gear, a rotating shaft, a flipping bracket, a flipping rod, a third rotating gear, a clamping cylinder, and a clamping arm. The first rotating gear and the second rotating gear are respectively disposed at both ends of the rotating shaft, and the first rotating gear meshes with the second rotating gear. The flipping bracket is disposed on the rotating shaft, and a flipping rod is disposed on the flipping bracket. The third rotating gear is disposed at one end of the flipping rod, and the third rotating gear meshes with the second rotating gear. A clamping cylinder is disposed on the flipping rod, and the clamping arm is disposed at the output of the clamping cylinder. On the shaft, the clamping cylinder is used to drive the opening and closing of the clamping arm. The rotation of the first gear drives the first rotating gear, the second rotating gear, and the rotating shaft to rotate synchronously, which in turn drives the flipping rod and the third rotating gear to rotate, which in turn drives the clamping cylinder and the clamping arm to rotate until they approach the key ring. The clamping cylinder controls the clamping arm to clamp the key ring. The flipping rod continues to rotate until it approaches the O-chain, causing the key ring to hook onto the O-chain, thereby forming an O-chain keychain. After hooking, the clamping cylinder controls the clamping arm to release, and the O-chain keychain is collected by the unloading mechanism.

[0027] like Figures 1-3 As shown, this utility model provides an O-chain keychain forming machine.

[0028] The device includes a base frame 1, an O-chain forming mechanism 2, a conveying mechanism 3, a flipping mechanism 4, a dropping mechanism 5, and a mounting frame 6. The conveying mechanism 3 is located on the upper surface of the base frame 1, the mounting frame 6 is located on one side of the conveying mechanism 3, the O-chain forming mechanism 2 is located on the mounting frame 6, the flipping mechanism 4 is located on one side of the O-chain forming mechanism 2, and the dropping mechanism 5 is located at the lower end of the mounting frame 6.

[0029] The O-chain keychain forming machine of this embodiment mainly consists of the following parts:

[0030] O-chain forming mechanism 2: This mechanism is used to form straight steel wires into ring-shaped O-rings and connect several O-rings into an O-chain. Specifically, this mechanism includes a spiral forming machine, a cutting mechanism 16, and a rotating mechanism 17. The spiral forming machine includes a motor, a drive shaft 7, a first gear 8, a second gear 9, a bevel gear 10, a connecting shaft 11, a connecting rod 12, a rack 13, a rotating shaft 14, a third gear 15, a forming plate, and a forming wheel. The motor drives the drive shaft 7 and the first gear 8 and the second gear 9 to rotate, thereby driving the bevel gear 10 and the connecting shaft 11 to rotate. The connecting shaft 11 drives the connecting rod 12 to move left and right, which in turn drives the rack 13 to move left and right, thereby driving the rotating shaft 14 to rotate. The rotating shaft 14 is used to transport the iron wire. The forming plate is set on one side of the output end of the rotating shaft 14, and the forming wheel is set on the forming plate. The forming wheel is used to form straight steel wires into ring-shaped O-rings. The cutting mechanism 16 is used to cut the annular O-rings, and the rotating mechanism 17 is used to grasp the cut annular O-rings and rotate them. The opening of the annular O-rings faces the output end of the rotating shaft 14. The forming wheel sequentially forms several sets of annular O-rings. The cutting mechanism 16 sequentially cuts the several sets of annular O-rings one by one, and the rotating mechanism 17 grasps the several sets of annular O-rings one by one to form an O-chain. When the rotating mechanism 17 grasps the next set of annular O-rings, the opening of the annular O-ring on the rotating mechanism 17 faces the next set of annular O-rings. During the grasping process, the opening of the annular O-ring on the rotating mechanism 17 is fitted onto the side wall of the next set of annular O-rings. After the grasping is completed, the rotating mechanism 17 rotates again, so that the opening of the second grasped annular O-ring faces the output end of the rotating shaft 14. This process is repeated to form an O-chain.

[0031] Conveying mechanism 3: This mechanism is used to convey key rings. Specifically, this mechanism is set as a vibratory feeder, which can arrange the key rings in a certain direction and spacing and convey them to the position of the flipping mechanism 4.

[0032] Flipping Mechanism 4: This mechanism is used to grab the key ring conveyed by the conveying mechanism 3, rotate it above the O-chain forming mechanism 2, and hook the formed O-chain to form an O-chain keychain. Specifically, this mechanism includes a first rotating gear 18, a second rotating gear, a rotating shaft 19, a flipping bracket 20, a flipping rod 21, a third rotating gear 22, a clamping cylinder 23, and a clamping arm 24.

The flipping bracket 20 is located on the rotating shaft 19, and the flipping rod 21 is located on the flipping bracket 20. The third rotating gear 22 is located at one end of the flipping rod 21 and is meshed with the second rotating gear. The clamping cylinder 23 is located on the flipping rod 21, and the clamping arm 24 is located on the output shaft of the clamping cylinder 23. The clamping cylinder 23 is used to drive the opening and closing of the clamping arm 24. The rotation of the first gear 8 drives the first rotating gear 18, the second rotating gear, and the rotating shaft 19 to rotate synchronously, which in turn drives the flipping rod 21 and the third rotating gear 22 to rotate, which in turn drives the clamping cylinder 23 and the clamping arm 24 to rotate until they are close to the key ring. The clamping cylinder 23 controls the clamping arm 24 to clamp the key ring. The flipping rod 21 continues to rotate until it is close to the O-chain, which drives the key ring to hook onto the O-chain, thus forming an O-chain key ring. After the hooking is completed, the clamping cylinder 23 controls the clamping arm 24 to release.

[0033] Material feeding mechanism 5: This mechanism is used to collect and convey the formed O-chain keychains. Specifically, this mechanism includes a guide plate 25 and a collection box. The guide plate 25 is located at the lower end of the mounting frame 6 to receive the O-chain keychains and guide them to the collection box. The collection box is located below the guide plate 25 to collect the O-chain keychains. Both the guide plate 25 and the collection box have protective layers on their surfaces to protect the falling O-chain keychains from scratches or damage.

[0034] The working process of the O-chain keychain forming machine in this embodiment is as follows:

[0035] First, place the straight steel wire into the input end of the spiral forming machine and place the key ring into the vibratory feeder.

[0036] Next, start the motor and vibratory feeder to make the spiral forming machine start working, and transport the key rings to the position of the flipping mechanism 4 in a certain direction and at a certain interval.

[0037] Then, the spiral forming machine forms straight steel wires into ring-shaped O-rings, and connects several O-rings into an O-chain through the cutting mechanism 16 and the rotating mechanism 17.

[0038] Next, the flipping mechanism 4 grabs the key ring conveyed by the conveying mechanism 3 and rotates it above the O-chain forming mechanism 2, hooking the formed O-chain to form an O-chain keychain.

[0039] Finally, the feeding mechanism 5 collects and conveys the formed O-chain keychains, guiding them into the collection box.

[0040] This application employs a spiral forming machine that can form straight steel wires into ring-shaped O-rings, and connect several O-rings into an O-chain through a cutting mechanism 16 and a rotating mechanism 17. This can save materials and time, and improve efficiency and quality.

[0041] This application employs a flipping mechanism 4, which can grab the key ring conveyed by the conveying mechanism 3 and rotate it above the O-chain forming mechanism 2, hooking the formed O-chain to form an O-chain keychain.
