Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and in particular to a multifunctional plastic welding machine. Background Technology

[0002] In modern industrial production, thermoplastics occupy an important position due to their unique performance advantages. Thermoplastics are a class of plastics that exhibit plasticity at specific temperatures, solidify upon cooling, and this process can be repeated multiple times. Their molecular structure consists of linear polymers, typically lacking active groups, and they do not undergo linear intermolecular cross-linking when heated. Waste thermoplastics can be recycled and reprocessed into new products; this recyclable characteristic aligns with the concepts of environmental protection and sustainable development. Furthermore, thermoplastics such as polyolefins (encompassing many categories including vinyl and olefin types), cellulose, polyether polyesters, and aromatic heterocyclic polymers not only possess excellent mechanical properties, electrical properties, chemical resistance, heat resistance, abrasion resistance, and dimensional stability, but also offer significant advantages over metal materials, such as light weight, ease of designing complex products, and low molding energy consumption. In recent years, with the vigorous development of the microelectronics industry, biomedical engineering and energy industry, the application fields of special plastics such as polypropylene (PP), high-density polyethylene (HDPE), nylon, polyvinyl chloride (PVC), PET, PFA and PVDF have been greatly expanded, making plastic welding technology a key technology in the production process of related industries.

[0003] Currently, existing plastic welding technologies typically involve placing a pair of parts to be welded on either side of a heating plate for preheating. Once the parts reach a molten state, they are pressed together to achieve welding. However, this technology has two major drawbacks: firstly, the high temperature of the heating plate radiates into the control box, causing excessively high temperatures inside the control box and severely impacting the lifespan of electrical components; secondly, the limited clamping space of the equipment cannot meet the welding needs of various styles and lengths of products, greatly restricting its application range. Therefore, this invention proposes a multi-functional plastic welding machine. Utility Model Content

[0004] The purpose of this invention is to address the problems in the existing plastic welding technology, such as the high-temperature diffusion radiation of the heating plate causing excessively high temperatures inside the control box, affecting the lifespan of electrical components, and the limited clamping space of the equipment making it difficult to meet the welding needs of various products. The invention proposes a multi-functional plastic welding machine.

[0006] Optionally, the driving mechanism includes a first side plate and a second side plate fixedly connected to the top of the base. One side of the first side plate is on the same plane as one side of the base. Multiple sets of limiting rods are fixedly connected between the first side plate and the second side plate. A movable plate is slidably connected to the multiple sets of limiting rods. A fixed plate is fixedly connected to the multiple sets of limiting rods. A servo motor is installed at the bottom of the fixed plate. A lead screw is fixedly connected to the output end of the servo motor. The lead screw is threadedly connected to the movable plate.

[0007] Optionally, the clamp includes a fixed base, and two sets of fixed bases in the two sets of clamps are respectively fixedly connected to the top of the first side plate and the movable plate.

Clamping blocks are installed on the opposite side of the fixed base and the rotating base. A sleeve is provided between the two sets of clamping blocks, and an opening is provided on one side of the sleeve.

[0008] Optionally, the fixed seat has a first groove on the side away from the connecting frame, and a threaded rod is rotatably connected in the first groove. The rotating seat has a second groove on the side away from the connecting frame that corresponds to the threaded rod, and a knob is threadedly connected to the end of the threaded rod away from the fixed seat.

[0009] Optionally, the movable component includes a positioning plate fixedly connected to the top of the base, a rotating shaft rotatably connected between the positioning plate and the first side plate, a connecting rod slidably connected on the rotating shaft, and one end of the connecting rod fixedly connected to the heating plate.

[0010] Optionally, a first handle is fixedly connected to the rotating shaft.

[0011] Optionally, the calibration mechanism includes a mounting base slidably connected to a set of limiting rods, a mounting plate rotatably connected to the mounting base, and a calibration baffle fixedly connected to the mounting plate on the side near the first side plate.

[0012] Optionally, a second handle is installed at the end of the mounting plate away from the mounting base.

[0013] Optionally, the heat dissipation assembly includes a first heat insulation plate installed in the base. One end of the first heat insulation plate is fixedly connected to the side wall of the base, and a second heat insulation plate perpendicular to it is installed at the other end of the first heat insulation plate. The first heat insulation plate, the second heat insulation plate, and the base form a heating chamber.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This utility model employs a first side plate clearance design in its drive mechanism, and the moving plate achieves flexible movement through a limiting rod and a lead screw. Combined with an adjustable clamp, it not only frees up clamping space, allowing the length and shape of the pipe fittings clamped on the first side plate to be less restricted and avoiding clamping interference, but also enables the moving plate to bring the clamp closer. It is suitable for welding needs of various styles and lengths of products, greatly expanding the application range of welding operations and improving practicality. In addition, the calibration mechanism can accurately calibrate the position of the parts, further ensuring welding accuracy and quality.

[0017] Furthermore, by setting up heat dissipation components, the heating chamber formed by the first and second heat insulation plates effectively blocks the high temperature generated by the heating plate from being transmitted to other spaces inside the base, reducing the temperature of areas such as the control box. At the same time, the coordinated work of the first and second fans can dissipate heat from the heating chamber and the inside of the base in a timely manner, avoiding excessively high temperatures inside the control box due to the diffusion and radiation of high temperature from the heating plate. This effectively ensures the service life of electrical components, reduces the probability of equipment failure, and improves the stability and reliability of the equipment.

[0018] In summary, this utility model effectively solves the problems of limited clamping and electrical damage in the prior art, and improves the practicality of the equipment, welding quality and stability. Attached Figure Description

[0035] Example

[0036] like Figure 1 and Figure 2 As shown, this utility model proposes a multifunctional plastic welding machine, including a base 1. A drive mechanism 2 is mounted on the top of the base 1, and two sets of clamps 3 are mounted on the drive mechanism 2. The drive mechanism 2 is used to bring the parts held by the two sets of clamps 3 closer together to achieve welding. The drive mechanism 2 includes a first side plate 21 and a second side plate 22 fixedly connected to the top of the base 1, and the positions of the first side plate 21 and the second side plate 22 are fixed. One side of the first side plate 21 is on the same plane as one side of the base 1, and adopts a clearance design. The length and shape of the pipe fittings clamped on the first side plate 21 are not greatly restricted, and the free space is completely released. The clamping will not interfere with the welding operation, which greatly improves the practicality of the welding operation. Two sets of limiting rods 23 are fixedly connected between the first side plate 21 and the second side plate 22, and the positions of the limiting rods 23 are fixed. A moving plate 24 is slidably connected to the two sets of limiting rods 23, and the moving plate 24 moves smoothly under the limiting action of the limiting rods 23. A fixed plate 25 is fixedly connected to multiple sets of limit rods 23. A servo motor 26 is installed at the bottom of the fixed plate 25, and the positions of the fixed plate 25 and the servo motor 26 are fixed. A lead screw 27 is fixedly connected to the output end of the servo motor 26. The lead screw 27 is threadedly connected to the moving plate 24. After the servo motor 26 is started, it drives the lead screw 27 to rotate. When the lead screw 27 rotates, it drives the moving plate 24 to move.

[0037] Please see Figure 3The clamp 3 includes a fixed base 31, with two sets of fixed bases 31 respectively fixedly connected to the top of the first side plate 21 and the movable plate 24. Thus, when the movable plate 24 moves, it can drive the two sets of clamps 3 closer together, causing the parts clamped in the two sets of clamps 3 to come into contact. The clamp 3 also includes a connecting frame 32 fixedly connected to one side of the fixed base 31, with a rotating seat 33 rotatably connected to the connecting frame 32. The rotating seat 33 is rotatably connected to the fixed base 31 through the connecting frame 32. Clamping blocks 34 are installed on opposite sides of the fixed base 31 and the rotating seat 33, and a sleeve 35 is provided between the two sets of clamping blocks 34. When the fixed base 31 and the rotating seat 33 are combined, they compress the sleeve 35 to clamp and fix the parts. An opening is provided on one side of the sleeve 35 to facilitate deformation of the sleeve 35 to clamp the parts. The fixed seat 31 has a first groove 36 on the side away from the connecting frame 32. A threaded rod 37 is rotatably connected in the first groove 36. The rotating seat 33 has a second groove 38 on the side away from the connecting frame 32, which corresponds to the threaded rod 37. A knob 39 is threadedly connected to the end of the threaded rod 37 away from the fixed seat 31. When the threaded rod 37 is located in the first groove 36 and the second groove 38, rotating the knob 39 moves it along the length of the threaded rod 37, thereby pressing the rotating seat 33 closer to the fixed seat 31 to complete the locking.

[0038] Furthermore, the welding machine also includes a heating plate 4 disposed between the two sets of clamps 3. The heating plate 4 is used to heat the welding surface of the parts. After the drive mechanism 2 moves the parts, the two parts come into contact with the two sides of the heating plate 4 respectively.

[0039] Furthermore, such as Figure 4 and Figure 5 As shown, the welding machine also includes a moving assembly 5 mounted on one side of the fixture 3. The moving assembly 5 is used to move the heating plate 4. The moving assembly 5 includes a positioning plate 51 fixedly connected to the top of the base 1, and the position of the positioning plate 51 is fixed. A rotating shaft 52 is rotatably connected between the positioning plate 51 and the first side plate 21, and the rotating shaft 52 rotates while remaining in its original position. A connecting rod 53 is slidably connected to the rotating shaft 52, and one end of the connecting rod 53 is fixedly connected to the heating plate 4. When the rotating shaft 52 rotates, it drives the heating plate 4 to perform a circular motion through the connecting rod 53, changing the position of the heating plate 4. This facilitates the heating plate 4 to move between two sets of parts when heating the welding surface of the parts. When the two parts come into contact, the heating plate 4 moves to the heating chamber to make room. At the same time, the sliding arrangement of the connecting rod 53 on the rotating shaft 52 facilitates the movement of the heating plate 4. After the moving plate 24 moves and drives one part to contact the heating plate 4, it pushes the heating plate 4 to make contact with another part. A first handle 54 is fixedly connected to the rotating shaft 52, and the first handle 54 facilitates the rotation of the rotating shaft 52.

[0040] Specifically, the welding machine also includes a calibration mechanism 6 located between the two sets of clamps 3. The calibration mechanism 6 is used to calibrate the position of the part. The calibration mechanism 6 includes a mounting base 61 slidably connected to a set of limiting rods 23. A mounting plate 62 is rotatably connected to the mounting base 61. A calibration baffle 63 is fixedly connected to the side of the mounting plate 62 near the first side plate 21. The mounting base 61 allows the mounting plate 62 to move the calibration baffle 63, bringing it closer to the part clamped on the first side plate 21 for position calibration. A second handle 64 is installed at the end of the mounting plate 62 away from the mounting base 61. The second handle 64 facilitates the rotation of the mounting plate 62, allowing the calibration baffle 63 to be rotated to the position of the part during calibration, after which the calibration baffle 63 is moved away to make way.

[0041] Furthermore, the aforementioned welding machine also includes a heat dissipation assembly 7 disposed in the base 1, which is used to dissipate heat from the high-temperature heating plate 4. The heat dissipation assembly 7 includes a first heat insulation plate 71 installed in the base 1. One end of the first heat insulation plate 71 is fixedly connected to the side wall of the base 1, and a second heat insulation plate 72 perpendicular to it is installed at the other end of the first heat insulation plate 71. The first heat insulation plate 71, the second heat insulation plate 72, and the base 1 form a heating chamber in which the heating plate 4 is preheated. The end of the second heat insulation plate 72 away from the first heat insulation plate 71 is fixedly connected to the side wall of the base 1. A first fan 73 and a second fan 74 are installed on the side of the base 1 fixedly connected to the first heat insulation plate 71. The first fan 73 is located on the side of the first heat insulation plate 71 closer to the second heat insulation plate 72. Multiple sets of ventilation holes 75 are opened at the bottom of the base 1. Through the first heat insulation plate 71 and the second heat insulation plate 72, the temperature inside the heating chamber can be effectively insulated from being transferred to other spaces within the base 1, reducing the temperature in other spaces and extending the service life of the electrical components. The first fan 73 is activated to dissipate heat from the heating chamber, while the second fan 74 ensures that the temperature in the base 1 does not become too high after activation.

[0042] Furthermore, the aforementioned welding machine also includes a control system, which includes a control display screen and multiple sets of control buttons. The CNC control system is a mature existing technology and will not be elaborated on here.

[0043] In this embodiment, the parts to be welded are placed inside the sleeves 35 of the two sets of clamps 3. By operating the second handle 64 to rotate the mounting plate 62, the calibration baffle 63 is rotated to the position of the part. By using the sliding of the mounting seat 61 on the limiting rod 23, the mounting plate 62 and the calibration baffle 63 are moved closer to the part clamped on the first side plate 21 to calibrate the position of the part and ensure welding accuracy. After calibration, the second handle 64 is rotated again to move the calibration baffle 63 to make room. By rotating the knob 39, it is moved along the threaded rod 37, pressing the rotating seat 33 closer to the fixed seat 31. The two sets of clamping blocks 34 then press the sleeves 35, and the deformation of the sleeves 35 achieves a stable clamping of the part. One set of the fixed seats 31 of the clamps 3 is fixed to the top of the first side plate 21, and the other set is fixed to the top of the moving plate 24, preparing for subsequent welding operations.

[0044] The heating plate 4 is first preheated in the heating chamber. After preheating, the first handle 54 in the moving assembly 5 can drive the rotating shaft 52 to rotate. The rotating shaft 52 drives the heating plate 4 to make circular motion through the connecting rod 53, so that the heating plate 4 moves to the position between the two parts.

[0045] The servo motor 26 is started, and its output drives the lead screw 27 to rotate. Since the lead screw 27 is threadedly connected to the moving plate 24, and the moving plate 24 can only move smoothly along the direction of the limiting rod 23 under the limiting action of the limiting rod 23, the rotation of the lead screw 27 drives the moving plate 24 to move, thereby causing the clamp 3 connected to the moving plate 24 and the clamped parts to move closer to another part. During the process of the parts moving closer, the heating plate 4 is pushed to contact the two sets of parts, and the heating plate 4 heats the welding surface of the parts until it reaches a molten state.

[0046] After the parts are heated to a molten state, the heating plate 4 returns to the heating chamber. Then, the heat dissipation assembly 7 begins operation. The first heat insulation plate 71 and the second heat insulation plate 72 effectively prevent heat transfer from the heating chamber to other spaces within the base 1, reducing the temperature in those spaces. The first fan 73 starts to dissipate heat from the heating chamber, and the second fan 74 starts to ensure that the overall temperature within the base 1 does not become too high, thereby extending the lifespan of the electrical components. The servo motor 26 continues to drive the lead screw 27 to rotate, causing the moving plate 24 to move further, pressing the two sets of parts together to achieve welding.

[0047] The entire welding process is operated and monitored through a control system. Operators can view the equipment's operating status and set welding parameters through the control display screen, and use multiple sets of control buttons to start or stop the servo motor 26, control the temperature of the heating plate 4, operate the moving components 5, the calibration mechanism 6, and the heat dissipation components 7, thereby achieving precise control over the workflow of the multi-functional plastic welding machine.

[0048] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
