Description

Technical Field

[0001] The utility model relates to the technical field of pipeline production equipment, in particular to a rotary melting machine. Background Art

[0002] A rotary welder, a type of hot melt machine, uses a transistor-based device to convert 50 / 60Hz electrical frequency into 20kHz or 40kHz high-frequency electrical energy, which is then supplied to the ultrasonic welder's converter. The converter converts the electrical energy into mechanical vibration energy for ultrasonic welding, and a voltage regulator transmits this converted mechanical energy to the ultrasonic welder's welding head.

The screw slider has a large capacity for adding electronic control components and excellent control characteristics. Photoelectric components can be installed on the base of the lifting mechanism, and the second slider of the lifting mechanism has a higher feed motion control accuracy after the light bar is installed. Micro-motion components can also be installed at both ends of the base of the lifting mechanism to improve the motion accuracy, accuracy and positioning accuracy of the second slider. The lifting mechanism uses a screw slider structure to improve the motion accuracy, accuracy and positioning accuracy, and improves the production quality and welding accuracy of the workpiece; however, the above patent document still has the following defects during implementation:

[0004] The rotary melting machine drives part of the plastic workpiece to be melted to rotate at high speed through a motor, causing the two plastic melting surfaces to rub against each other to generate heat, and then pressurize and weld them. Due to the different strengths of different types of plastic workpieces, when the device drives the plastic workpiece inside the rotating seat downward, the pressure is difficult to control and is too strong, making the plastic workpiece prone to excessive deformation, cracking or internal structural damage during pressurized welding, thereby affecting the quality and performance of the product, increasing the waste of raw materials, and increasing production costs.

A controller 4 is fixedly connected to the top of the workbench 1, and the controller 4 is located on the right side of the fixed column 2.

[0026] Specifically, in order to prevent excessive deformation, cracking or internal structural damage of plastic workpieces during pressurized welding, thereby affecting product quality and performance, increasing the waste of raw materials and increasing production costs, refer to Figure 4 and Figure 5 In this embodiment, a buffer assembly 31 is provided above the fixed plate 3, and the buffer assembly 31 includes two fixed blocks 32. The top of the fixed block 32 on the right is fixedly connected to a fixed splint 33, and the top of the fixed block 32 on the left is provided with a groove 1, and the top of the inner wall of the groove 1 is fixedly connected to a connecting plate 34, and the bottom of the connecting plate 34 is fixedly connected to the top of the fixed block 32, and the top of the connecting plate 34 is fixedly connected to an electric push rod 2 35, and the output end of the electric push rod 2 35 is fixedly connected to a telescopic rod 2 36, and the right side of the telescopic rod 2 36 is fixedly connected to a movable splint 37.

[0027] During the implementation process, the electric push rod 2 35 is turned on to drive the telescopic rod 2 36 to extend to the right. During the extension of the telescopic rod 2 36, the movable splint 37 is driven to move to the right. When the right side of the movable splint 37 contacts the left side of the fixed splint 33, the plastic workpiece at the bottom will be fixed inside the base limit seat 381, and no offset will occur during welding.

[0028] For further information, see Figure 4 In this embodiment, the back of the fixed splint 33 is fixedly connected to a fixed frame 371, the left front side of the fixed frame 371 is fixedly connected to the back of the connecting plate 34, a sliding groove is opened inside the fixed frame 371, and the back of the movable splint 37 is fixedly connected to a slider 372, and the outer surface of the slider 372 is slidably connected to the inner wall of the sliding groove.

[0029] During the implementation process, the movable clamping plate 37 will drive the slider 372 to move in the inner wall of the sliding groove opened inside the fixing frame 371 while moving, so that the movable clamping plate 37 is more stable during the movement process.

[0030] For further information, see Figure 5 In this embodiment, the top of the fixed plate 3 is fixedly connected to two bases 38, and the two bases 38 are symmetrically arranged with respect to the center of the fixed frame 371. The top of the fixed plate 3 is fixedly connected to a limited seat 381, and the top of the base 38 is fixedly connected to two fixing rods 382. The outer surfaces of the two fixing rods 382 are slidably connected to the inner wall of the fixed block 32, and the outer surfaces of the two fixing rods 382 are sleeved with springs 383.

When the plastic workpiece moves downward, it will drive the two fixed blocks 32 to move downward on the outer surface of the fixed rod 382. When the fixed block 32 moves, it will squeeze the spring 383 on the outer surface of the fixed rod 382 to cause it to deform. The deformed spring 383 will generate an upward elastic force, so that the two plastic workpieces can fit tightly together, and at the same time ensure that the plastic workpiece is prevented from being easily deformed, cracked or damaged in the internal structure during pressurized welding, thereby affecting the quality and performance of the product, reducing the waste of raw materials and reducing production costs.

[0032] Example 2

[0033] This embodiment fixes the plastic workpiece located at the top on the basis of the first embodiment.

[0034] Specifically, in order to achieve the purpose of fixing the plastic workpiece in the rotating seat 28 so that the plastic workpiece does not shake during welding and cause uneven welding, refer to Figure 2 and Figure 3In this embodiment, the outer surface of the fixed column 2 is fixedly connected to two connecting blocks 21, and the front faces of the two connecting blocks 21 are commonly connected to a hollow box 22.

The outer surface of the hollow frame 25 is slidably connected to the inner wall of the hollow box 22, and the inner wall of the hollow frame 25 is fixedly connected to a motor 26. The output end of the motor 26 is fixedly connected to a rotating shaft 27, and the bottom of the rotating shaft 27 is fixedly connected to a rotating seat 28.

[0035] During the implementation process, the electric push rod 23 is turned on to drive the telescopic rod 24 to extend downward. When the telescopic rod 24 extends downward, it will drive the hollow frame 25 to move downward. The downward movement of the hollow frame 25 will drive the rotating seat 28 to move downward, so that the plastic workpiece fixed inside the rotating seat 28 contacts the plastic workpiece at the bottom. The motor 26 is turned on to drive the rotating shaft 27 to rotate. When the rotating shaft 27 rotates, it will drive the rotating seat 28 to rotate, so that the surfaces of the two plastic workpieces can rotate and rub to weld.

[0036] For further information, see Figure 3 In this embodiment, a fixing component 29 is provided inside the rotating seat 28, and the fixing component 29 includes a limit frame 291, the top of the limit frame 291 is fixedly connected to the top of the inner wall of the rotating seat 28, and the inner wall of the rotating seat 28 is rotatably connected with a two-way threaded rod 292, and the front of the two-way threaded rod 292 is fixedly connected to a rotating block 293, and the outer surface of the two-way threaded rod 292 is threadedly connected to two moving blocks 294, and the bottoms of the two moving blocks 294 are fixedly connected to a splint 295, and the ends of the two splints 295 away from each other are fixedly connected to a sliding rod 296, and the outer surfaces of the two sliding rods 296 are slidably connected to the inner wall of the rotating seat 28.

[0037] During the implementation process, first insert the upper part of the plastic workpiece to be welded into the rotating seat 28, rotate the rotating block 293 clockwise to drive the bidirectional threaded rod 292 to rotate, and the bidirectional threaded rod 292 will drive the two moving blocks 294 to move closer to each other while rotating. When the two moving blocks 294 move, they will drive the two clamps 295 to move closer to each other and contact the surface of the plastic workpiece, so that the plastic workpiece can be fixed inside the rotating seat 28, and there will be no shaking during welding, which will cause uneven welding. The strength of the weld is increased, and the production quality of the product is improved.

[0038] The working principle of the present invention is as follows: when the staff uses the device, first insert the upper part of the plastic workpiece to be welded into the rotating seat 28, rotate the rotating block 293 clockwise to drive the bidirectional threaded rod 292 to rotate, and the bidirectional threaded rod 292 rotates while driving the two moving blocks 294 to move closer to each other, and the two moving blocks 294 move while driving the two clamping plates 295 to move closer to each other so that the surface of the plastic workpiece can be contacted, so that the plastic workpiece can be fixed inside the rotating seat 28, and there will be no shaking during welding, which will cause uneven welding, thereby increasing the strength of the weld and improving To improve the production quality of the product, insert the lower half of the plastic workpiece to be welded into the limit seat 381, turn on the electric push rod 2 35 to drive the telescopic rod 2 36 to extend to the right, and the extension of the telescopic rod 2 36 will drive the movable splint 37 to move to the right. When the right side of the movable splint 37 contacts the left side of the fixed splint 33, the plastic workpiece at the bottom will be fixed inside the base limit seat 381, and no deviation will occur during welding. When the movable splint 37 moves, it will drive the slider 372 to move in the inner wall of the slide groove opened in the fixed frame 371. Turn on the electric push rod 1 23 to drive The telescopic rod 24 extends downward, and the telescopic rod 24 extends downward, which drives the hollow frame 25 to move downward. The downward movement of the hollow frame 25 drives the rotating seat 28 to move downward, so that the plastic workpiece fixed inside the rotating seat 28 contacts the plastic workpiece at the bottom. The motor 26 is turned on to drive the rotating shaft 27 to rotate. When the rotating shaft 27 rotates, it drives the rotating seat 28 to rotate, so that the surfaces of the two plastic workpieces can rotate and rub to weld. When the plastic workpieces are welded, the device drives the rotating seat 28 to move downward, so that the plastic workpiece at the bottom is subjected to pressure and is fixed on the limit seat 3. When the inner wall of the plastic workpiece 81 moves downward, the two fixing blocks 32 will be driven to move downward on the outer surface of the fixing rod 382 when the plastic workpiece moves downward. When the fixing blocks 32 move, the spring 383 on the outer surface of the fixing rod 382 will be squeezed to deform it. The deformed spring 383 will generate an upward elastic force, so that the two plastic workpieces can fit tightly together, and at the same time, it is ensured that the plastic workpiece is prevented from being easily deformed, cracked or damaged in the internal structure during pressurized welding, thereby affecting the quality and performance of the product, reducing the waste of raw materials and reducing production costs.
