Detailed Implementation
[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0020] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a pliers for glass bottle production, including a mounting plate 1; a placement seat 2 is provided on the top of the mounting plate 1, and a mounting groove 3 is opened on the top of the mounting plate 1. A bidirectional lead screw 4 is provided inside the mounting groove 3, and both ends of the bidirectional lead screw 4 are rotatably connected to the interior of the mounting plate 1. A servo motor 5 is installed on one end of the mounting plate 1, and the output end of the servo motor 5 is fixed to one end of the bidirectional lead screw 4. A slider 6 is provided on the surface of the bidirectional lead screw 4. There are two sliders 6, which are respectively located on the forward and reverse thread sections of the bidirectional lead screw 4. A clamping arm 7 is fixed on the top of the slider 6, and a pliers assembly is installed on the opposite side of the clamping arm 7. The pliers assembly includes a connecting block 8 and a chuck 9. The chuck 9 is connected to the connecting block 8. The connecting blocks 8 are fixedly connected. Two connecting slots 10 are opened on the opposite side of the clamping arm 7. The connecting blocks 8 are inserted into the connecting slots 10. An adjustment slot 11 is opened inside the top of the clamping arm 7. A fixing mechanism for fixing the connecting blocks 8 is set inside the adjustment slot 11. The bidirectional lead screw 4 is driven to rotate by the servo motor 5. The rotation of the bidirectional lead screw 4 drives the two sliders 6 to move along the inner wall of the mounting slot 3 in opposite or opposite directions. The movement of the sliders 6 drives the clamping arm 7 to move. The movement of the clamping arm 7 drives the jaw assembly to move, thereby realizing the clamping or releasing of the glass bottle. The fixing mechanism can facilitate the disassembly or replacement of the jaw assembly to adapt to different specifications of glass bottles and improve the versatility of the equipment.
[0021] Reference Figure 4As shown, in this embodiment: the fixing mechanism includes a screw 12 threadedly connected inside the clamping arm 7. A handle 13 is fixed to one end of the screw 12 located outside the clamping arm 7. The other end of the screw 12 extends into the adjusting groove 11 and is fixed to a pressing block 14. Two pressure plates 15 slide inside the adjusting groove 11, located at opposite ends of the pressing block 14. A fixing rod 16 is fixed to one side of each pressure plate 15. A fixing groove 17 matching the fixing rod 16 is opened at one end of the connecting block 8 located inside the connecting groove 10. A spring 18 is sleeved on the surface of the fixing rod 16. One end of the spring 18 is fixed to the inside of the adjusting groove 11, and the other end of the spring 18 is fixed to the pressure plate. 15 is fixed. By rotating the handle 13, the screw 12 is rotated, which in turn rotates the pressing block 14, thereby pressing the two pressure plates 15. After being pressed, the pressure plates 15 move the fixing rod 16 and lock it into the inside of the fixing groove 17, thus fixing the connecting block 8 and realizing the fixed installation of the jaw assembly. When it is necessary to disassemble the jaw assembly, rotate the handle 13 in the opposite direction to rotate the pressing block 14 to the vertical direction, so that the two pressure plates 15 are no longer pressed by the pressing block 14. Then, they are pushed by the rebound force of the spring 18, which moves the fixing rod 16 out of the inside of the fixing groove 17. At this time, the jaw assembly can be removed from the clamping arm 7. The operation is simple and convenient.
[0022] Reference Figure 4 As shown in this embodiment: two limiting plates 19 are fixed on both sides inside the adjusting groove 11, and limiting grooves 20 matching the two limiting plates 19 are opened at both ends of the two pressure plates 15. By setting the limiting plates 19 and limiting grooves 20, the pressure plates 15 can be limited to avoid the pressure plates 15 from shifting during the movement, thus ensuring the stability of the movement of the pressure plates 15.
[0023] Reference Figure 4 As shown in this embodiment: the surface of the screw 12 is covered with an anti-slip pad 21. The two sides of the anti-slip pad 21 abut against the clamping arm 7 and the handle 13 respectively. The anti-slip pad 21 can increase the firmness between the handle 13 and the clamping arm 7, prevent loosening, and affect the fixed installation effect of the clamping claw assembly.
[0024] Reference Figure 2 As shown in this embodiment: the inner wall of the chuck 9 is provided with a flexible bonding layer, and the surface of the flexible bonding layer is provided with several anti-slip protrusions. Through the flexible bonding layer and the anti-slip protrusions, the friction between the chuck 9 and the glass bottle can be increased, improving the clamping stability of the glass bottle and preventing it from falling off during transportation or stacking. This further ensures production efficiency and product qualification rate. At the same time, the flexible bonding layer can also protect the surface of the glass bottle to avoid scratches or damage, thus improving the practicality of the equipment.
[0025] Working principle: The user drives the bidirectional lead screw 4 to rotate via the servo motor 5. The rotation of the bidirectional lead screw 4 causes the two sliders 6 to move along the inner wall of the mounting groove 3 in opposite or opposite directions. The movement of the sliders 6 causes the clamping arm 7 to move, which in turn causes the jaw assembly to move, thereby clamping or releasing the glass bottle. The fixed mechanism allows for easy disassembly or replacement of the jaw assembly to accommodate different sizes of glass bottles, improving the equipment's versatility. Rotating the handle 13 drives the screw 12 to rotate, which in turn drives the extrusion block 14 to rotate, thus extruding the two pressure plates 15. The pressure plates 15, under pressure, cause the fixing rod 16 to move and engage with the fixing groove 17, thereby fixing the connecting block 8 and securing the jaw assembly. When the jaw assembly needs to be disassembled, rotating the handle 13 in the opposite direction rotates the extrusion block 14 to a vertical position, freeing the two pressure plates 15 from the pressure block. The compression of 14 is followed by the rebound force of spring 18, which drives the fixing rod 16 to move out of the fixing groove 17. At this time, the clamping claw assembly can be removed from the clamping arm 7. The operation is simple and convenient. The limiting plate 19 and the limiting groove 20 can limit the pressure plate 15 to prevent the pressure plate 15 from shifting during the movement, thus ensuring the stability of the movement of the pressure plate 15. The anti-slip pad 21 can increase the firmness between the handle 13 and the clamping arm 7, preventing loosening and affecting the fixed installation effect of the clamping claw assembly. The flexible bonding layer and anti-slip protrusions can increase the friction between the chuck 9 and the glass bottle, improve the clamping stability of the glass bottle, and prevent it from falling off during transportation or stacking, further ensuring production efficiency and product qualification rate. At the same time, the flexible bonding layer can also protect the surface of the glass bottle to avoid scratches or damage, thus improving the practicality of the equipment.
[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
