Description

Technical Field

[0001] This utility model relates to the field of footwear manufacturing, and in particular to a double-headed high-frequency synchronous welding machine. Background Technology

[0002] In footwear manufacturing, high-frequency welding technology is widely used in the rapid welding and trimming processes of shoe upper materials (such as TPU film, EVA foam, and synthetic leather). Traditional shoe material welding equipment involves human-machine interaction in the high-frequency welding process: during material handling, hands must enter a 200mm x 200mm high-risk work area. This easily leads to burns and poses a threat to the health and safety of workers. Utility Model Content

[0003] To address the shortcomings mentioned above in the background technology, this utility model provides a dual-head high-frequency synchronous fuse machine.

[0004] The present invention adopts the following technical solution:

[0005] A dual-head high-frequency synchronous fuse cutter, characterized in that the fuse cutter comprises:

[0006] The workbench has symmetrical openings and a liftable machine head on top;

[0007] The two placement plates are provided corresponding to the two openings and can be raised, lowered and translated synchronously.

[0008] A driving mechanism, comprising a first connecting arm, a second connecting arm, a third connecting arm, a turntable, and a mounting plate, wherein the mounting plate is fixed below the placement plate, the first connecting arm is hinged to the mounting plate and the placement plate at both ends, the second connecting arm is hinged to the third connecting arm and the placement plate at both ends, and the mounting plate is hinged to the middle section, and the turntable is hinged to the other end of the third connecting arm.

[0009] Rotating the turntable, in conjunction with the first connecting arm, the second connecting arm, and the third connecting arm, causes the placement plate to rise, fall, and translate, in order to align with or move away from the machine head.

[0010] As a further improvement, the second connecting arm is composed of an L-shaped rod and a diagonal rod connected end to end. The diagonal rod is inclined, and the two ends of the L-shaped rod are respectively hinged to the bottom surface of the placement plate and the side surface of the mounting plate. The other end of the diagonal rod is hinged to the third connecting arm.

[0011] As a further improvement, a drive mechanism is provided on each side of the placement plate, and the two turntables are coaxially sleeved on the rotating shaft, which is driven by a drive motor below the worktable.

[0012] As a further improvement, a base is provided below the worktable to cover the drive mechanism for protection.

[0013] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: In use, rotating the turntable, in conjunction with the first, second, and third connecting arms, causes the placement plate to rise, fall, and translate, moving it away from the machine head for convenient material placement. After the shoe upper material to be processed is placed on the placement plate, the turntable is rotated in the opposite direction, causing the placement plate to rise, fall, and translate under the action of multiple connecting arms, aligning it with the machine head. Then, the machine head descends to process the material. After the material is processed, the turntable is rotated again, in conjunction with the first, second, and third connecting arms, causing the placement plate to rise, fall, and translate, moving it away from the machine head for convenient material removal. This utility model achieves the compound movement of the placement plate through precise mechanical linkage of the drive mechanism, enabling workers to move away from the machine head during human-machine interaction—specifically, when picking up and placing materials—reducing the risk of burns and ensuring the health and safety of personnel.

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0020] As attached Figure 1As shown, a dual-head high-frequency synchronous welding machine includes a worktable 1, a placement plate 3, and a drive mechanism 4. The worktable 1 is integrally cast from high-strength cast iron, with a precision-ground surface ensuring a flatness error ≤0.05mm / m. Two rectangular openings 11 are symmetrically arranged on the worktable 1, with a machine head 2 positioned directly above each opening 11. The machine head 2 achieves vertical lifting via a hydraulic cylinder, with an adjustable lifting stroke of 0-150mm and a positioning accuracy of ±0.02mm. The machine head 2 integrates a 20kW high-frequency heating module and a hydraulic stamping system, with a temperature control range of 50-300℃±2℃. The two placement plates 3 are made of special mold steel and undergo hard anodizing treatment. The two placement plates 3 are positioned corresponding to the two openings 11. In operation, the shoe upper material to be processed is placed on the placement plate 3, and the machine head 2 descends to process the material. Positioning pins are provided on the placement plate 3 for material positioning. Simultaneous processing with both machine heads 2 increases the processing frequency and thus improves efficiency.

[0021] Further details are attached. Figures 1 to 3 As shown, the two placement plates 3 are driven by the drive mechanism 4 to achieve synchronous lifting and translation, so that the placement plates 3 can be aligned with the machine head 2 for processing, or moved away from the machine head 2 for easy material handling and to reduce the risk of burns. The drive mechanism 4 adopts a multi-link composite transmission design, mainly including a first connecting arm 41, a second connecting arm 42, a third connecting arm 43, a turntable 44, and a mounting plate 46. This mechanism achieves the composite movement of the placement plates 3 through precise mechanical linkage. The specific structure and working principle are as follows:

[0022] As attached Figures 3 to 5 As shown, the mounting plate 46 is fixed below the placement plate 3. The first connecting arm 41 is hinged to the mounting plate 46 and the placement plate 3 at both ends, and the second connecting arm 42 is hinged to the third connecting arm 43 and the placement plate 3 at both ends, with the mounting plate 46 hinged in the middle. Specifically, the second connecting arm 42 is composed of an L-shaped rod 421 and a diagonal rod 422 connected end to end. The diagonal rod 422 is inclined. The two ends of the L-shaped rod 421 are hinged to the bottom surface of the placement plate 3 and the side surface of the mounting plate 46, respectively, and the other end of the diagonal rod 422 is hinged to the third connecting arm 43. The other end of the third connecting arm 43 is hinged to a turntable 44. In use, by rotating the turntable 44, the first connecting arm 41, the second connecting arm 42, and the third connecting arm 43 are linked to raise, lower, and move the placement plate 3 to align with or move away from the machine head 2.

[0023] Furthermore, a drive mechanism 4 is provided on each side of the placement plate 3, and two turntables 44 are coaxially sleeved on a rotating shaft 47, which is driven by a drive motor 45 located below the worktable 1. Specifically, the output shaft of the drive motor 45 is fixedly connected to the rotating shaft 47, and the drive motor 45 drives the rotating shaft 47 to rotate the turntables 44, thereby realizing the lifting, lowering, and translation of the placement plate 3. This structural design makes the placement plate 3 subjected to balanced forces, and the lifting, lowering, and translation are more stable.

[0024] Preferably, as shown in the appendix Figure 1 and Figure 3 As shown, a base 12 is provided below the worktable 1 to cover the drive mechanism 4 for protection and to support the entire equipment.

[0025] In summary, when using this invention, rotating the turntable 44, in conjunction with the first connecting arm 41, the second connecting arm 42, and the third connecting arm 43, causes the placement plate 3 to rise, fall, and move horizontally away from the machine head 2 for easy material placement. After placing the shoe upper material to be processed on the placement plate 3, rotating the turntable 44 in the opposite direction causes the placement plate 3 to rise, fall, and move horizontally under the action of multiple connecting arms, aligning it with the machine head 2. Then, the machine head 2 descends to process the material. After the material is processed, rotating the turntable 44 again, in conjunction with the first connecting arm 41, the second connecting arm 42, and the third connecting arm 43, causes the placement plate 3 to rise, fall, and move horizontally away from the machine head 2 for easy material removal. This invention achieves the compound movement of the placement plate 3 through the precise mechanical linkage of the drive mechanism 4, enabling workers to move away from the machine head 2 during human-machine interaction (material handling), reducing the risk of burns and ensuring the health and safety of workers.

[0026] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
