Description

Technical Field

[0001] This invention relates to the field of vulcanizing machine technology, and in particular to an oil-resistant rubber rope joint forming device. Background Technology

[0002] While current transformer sealing gasket manufacturing tools have made some progress in the splicing of circular rubber ropes, problems such as the separate design of the vulcanizing machine and controller, inconvenient operation, and lack of effective rubber rope fixing devices directly affect manufacturing efficiency and finished product quality, making it difficult to meet the high-efficiency and precise requirements of on-site operations. With the continuous expansion of the transformer manufacturing and maintenance market, the demand for high-quality and high-efficiency sealing gasket manufacturing tools is becoming increasingly urgent. Summary of the Invention

[0003] To address the above shortcomings, this invention provides an oil-resistant rubber rope interface forming device that integrates the vulcanizing machine and controller into a single unit, effectively improving issues such as rubber rope fixation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An oil-resistant rubber rope interface forming device includes a control box, which contains a power supply system and a temperature control system. The power supply system and the temperature control system are electrically connected. A support frame is provided at the upper end of the control box, and a welding mechanism is provided on the support frame. A positioning mechanism is provided on the control box next to the welding mechanism.

[0006] The welding mechanism includes an upper heating module and a lower heating module. The upper heating module is fixedly connected to the support frame via a bracket, and the lower heating module is fixedly installed on the control box below the upper heating module. Both the upper heating module and the lower heating module are electrically connected to the temperature control system.

[0007] Through the above scheme, the power supply system is responsible for providing the necessary power support for the entire device, while the temperature control system is used to precisely control the temperature and heating time of the welding mechanism to ensure that the temperature conditions during the welding process meet the requirements, thereby ensuring the quality of the rubber rope joint. The welding mechanism is fixedly installed on the control box, which highly integrates the vulcanizing machine and the controller to form a compact and lightweight integrated machine. The positioning mechanism is set next to the welding mechanism and is mainly used to ensure that the rubber rope to be processed can be welded in the correct position. A good positioning mechanism helps to improve the consistency and reliability of the finished product and avoid product quality problems caused by position deviation.

[0008] Furthermore, the support frame includes two struts, a support rod, and a connecting rod. Both struts are fixedly mounted on the control box via a fixed base. Both ends of the support rod are connected to the struts via connecting rods. The connecting rods are slidably connected to the struts. The support rods are fixedly connected to the connecting rods. A bracket is fixedly connected to the support rods.

[0009] With the above-mentioned further solution, since the connecting rod and the support rod adopt a sliding connection, it is easy to adjust the height of the upper heating module connected to the support rod via the bracket.

[0010] Furthermore, the support frame also includes a first lead screw, one end of which is rotatably connected to the control box, and the other end is provided with a first handle. The first lead screw is threadedly connected to the connecting rod.

[0011] With the above-mentioned further solutions, the threaded connection between the first lead screw and the connecting rod can adjust the position of the connecting rod by rotating the first handle, and can also fix the connecting rod at a certain height to prevent the connecting rod from sliding down the support rod due to its own weight.

[0012] Furthermore, the power supply system includes a power source and a switch. The power source is electrically connected to the temperature control system, and a switch is provided between the power source and the temperature control system. The power source is electrically connected to the upper heating module and the lower heating module through the temperature control system.

[0013] Through the above-mentioned further solutions, the power supply provides a stable power supply, and the switch allows the operator to cut off the power when needed, improving the safety and convenience of operation.

[0014] Furthermore, the temperature control system includes a time relay, a PLC controller, and a temperature controller. The time relay is connected to the PLC controller via a wire, and the PLC controller is connected to the temperature controller via a wire. The PLC controller is also connected to a reset switch and an alarm via a wire. The temperature controller is connected to the lower heating module and the upper heating module via a wire. The time relay, PLC controller, and temperature controller are all connected to a power supply via wires.

[0015] The above-mentioned further solutions enable precise control of the heating time and temperature of the upper and lower heating modules. PLC controllers are usually equipped with touch screens or operation panels, which allow for intuitive setting and monitoring of parameters such as temperature and time, simplifying the operation process.

[0016] Furthermore, an upper heat insulation plate is provided between the upper heating module and the bracket, and a lower heat insulation plate is provided between the lower heating module and the control box.

[0017] Through the above-mentioned further solutions, the upper and lower heat insulation plates effectively prevent the heat generated by the upper and lower heating modules from being conducted to other places, reducing heat loss, ensuring that the temperature of the heating modules is more concentrated, and improving heating efficiency.

[0018] Furthermore, the lower heating module is fixedly connected to a template, and the template is provided with a groove for fitting the rubber rope.

[0019] Through the above-mentioned further solutions, templates with different shaped grooves can be installed, allowing for welding of the adhesive rope at different angles. The templates ensure that the adhesive rope is heated evenly during the welding process, avoiding local overheating or insufficient heating, and ensuring the strength and sealing of the weld joint. The grooves enable the positioning and fixing of the adhesive rope to be very quick, reducing the preparation time before each welding and improving production efficiency.

[0020] Furthermore, the positioning mechanism includes a semi-frame platform, a pressure rod, a second lead screw, and a slide rod. The semi-frame platform includes an upper platform, a lower platform, and a vertical plate. The two ends of the vertical plate are respectively connected to the upper platform and the lower platform. The pressure rod is threadedly connected to the upper platform. The pressure rod has a pressure block at one end located between the upper and lower platforms and a third handle at the other end. A connecting block is provided on the side of the vertical plate away from the upper platform. The connecting block is threadedly connected to the second lead screw and slidably connected to the slide rod. One end of the second lead screw is rotatably connected to the control box, and the other end has a second handle. One end of the slide rod is fixedly installed on the control box, and the other end has a limiting platform.

[0021] The above-mentioned further solution allows for adjusting the height of the upper and lower platforms of the semi-frame platform using the second lead screw, so that the upper surface of the lower platform is flush with the bottom of the tank or the upper surface of the lower heating module. Then, the pressure block on the pressure rod presses the adhesive rope onto the lower platform, ensuring that the position of the adhesive rope remains fixed during the welding process.

[0022] Furthermore, the control box is also equipped with a cutting fixing seat, which includes a rubber rope seat, a third screw, and a slider. The rubber rope seat is fixedly installed on the control box. One end of the rubber rope seat is provided with a stop block, and the other end is provided with a connecting platform. The slider is slidably connected to the rubber rope seat and is located between the stop block and the connecting platform. The third screw is threadedly connected to the connecting platform. One end of the third screw passes through the connecting platform and is rotatably connected to the stop block, and the other end is provided with a fourth handle.

[0023] The above-mentioned further solution provides a stable platform for fixing the descent rope to the rope holder, making it easier to cut the rope.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. The power supply system is responsible for providing the necessary power support for the entire device, while the temperature control system is used to precisely control the temperature and heating time of the heating module to ensure that the temperature conditions during the welding process meet the requirements, thereby ensuring the quality of the adhesive rope joint.

[0026] 2. The welding mechanism is fixedly installed on the control box, which highly integrates the vulcanizing machine and the controller to form a compact and lightweight integrated machine.

[0027] 3. The positioning mechanism is located next to the welding mechanism. It is mainly used to ensure that the rubber rope to be processed can be welded in the correct position. A good positioning mechanism helps to improve the consistency and reliability of the finished product and avoid product quality problems caused by position deviation. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Example:

[0040] Reference Figure 1 As shown, an oil-resistant rubber rope interface forming device includes a control box 1. Two support rods 41 are fixedly installed on the control box 1 via a fixed base 411. The two support rods 41 are respectively connected to both ends of a support rod 42 via connecting rods 43. The connecting rods 43 are slidably connected to the support rods 41, and the support rod 42 is fixedly connected to the connecting rods 43. Since the connecting rods 43 and the support rods 41 are slidably connected, the height of the support rod 42 can be easily adjusted. A first lead screw 44 is rotatably connected to the control box 1 next to the support rods 41. The first lead screw 44 is threadedly connected to the connecting rods 43. A first handle 441 is provided on the end opposite to the connection end of the first lead screw 44 and the control box 1. The threaded connection between the first lead screw 44 and the connecting rod 43 allows the position of the connecting rod 43 to be adjusted by rotating the first handle 441, thereby adjusting the height of the support rod 42. It can also fix the connecting rod 43 at a certain height to prevent the connecting rod 43 from sliding down the support rod 41 due to its own weight.

[0041] Reference Figures 2-4As shown, a bracket 511 is fixedly connected to the support rod 42, and an upper heating module 51 is fixedly connected to the bracket 511. A lower heating module 52 is fixedly installed on the control box 1 below the upper heating module 51. The upper heating module 51 and the lower heating module 52 clamp each other to weld the rubber rope interface. The upper heating module 51 is fixedly connected to the support rod 42 through the bracket 511, and the height of the heating module can be adjusted by the first lead screw 44.

[0042] An upper heat insulation plate 512 is provided between the upper heating module 51 and the bracket 511, and a lower heat insulation plate 521 is provided between the lower heating module 52 and the control box 1. The upper heat insulation plate 512 and the lower heat insulation plate 521 effectively block the heat generated by the upper heating module 51 and the lower heating module 52 from being conducted to other places, reducing heat loss, ensuring that the temperature of the heating module is more concentrated, and improving heating efficiency.

[0043] The lower heating module 52 is fixedly connected to a template 522, which has a groove 522a for fitting the adhesive rope. The template 522 ensures that the adhesive rope is heated evenly during the welding process, avoiding local overheating or insufficient heating, and ensuring the strength and sealing of the weld joint. The groove 522a makes the positioning and fixing of the adhesive rope very fast, reducing the preparation time before each welding and improving production efficiency.

[0044] Further expansion allows for the installation of templates 522 with grooves 522a of different shapes, enabling the testing of welding at different angles for the rubber rope. For example, by setting straight hot vulcanization welding grooves and right-angle hot vulcanization welding grooves, the ends of the rubber rope need to be cut into 45° bevels when welding the rope. Figure 4 As shown, the right-angle heat vulcanization weld groove is used to right-angle position two rubber ropes with 45° bevels cut, such as... Figure 4 As shown, the straight-line hot vulcanization welding groove of the rubber rope is used to position two rubber ropes with 45° bevels in a straight line. The rubber ropes are generally standard strip products with a certain length. At the joint position, the rubber ropes must be cut to a certain size and then hot vulcanized and welded together. When the length of the rubber rope is insufficient and needs to be continued, the end of the rubber rope being used and the front end of the new rubber rope are cut into 45° bevels and then spliced ​​together in a straight line. This helps to increase the hot vulcanization welding area and improve the welding strength.

[0045] The lower heating module 52 includes a hot plate and a heating aluminum plate. The hot plate has a groove, and the heating aluminum plate is placed in the groove. The lower heating module 52 has the same structure as the upper heating module 51. The heating aluminum plate has good thermal conductivity, which can quickly and evenly distribute heat throughout the lower heating module 52, ensuring that the adhesive rope is heated evenly during the welding process and avoiding local overheating or insufficient heating. At the same time, the weight is reduced. The heating aluminum plate is made of Ly11 high-strength aviation aluminum plate, which reduces the volume and weight of the lower heating module 52, thereby reducing energy consumption while accelerating the heating.

[0046] Reference Figure 6 As shown, the control box 1 contains a power supply system 2 and a temperature control system 3. The power supply system 2 includes a power source 21 and a switch 22. The temperature control system 3 includes a time relay 31, a PLC controller 32, and a temperature controller 33. The power source 21 is connected to the time relay 31, the PLC controller 32, and the temperature controller 33 via wires. The switch 22 is located between the power source 21 and the electrical connections of the time relay 31, the PLC controller 32, and the temperature controller 33, and is used to disconnect or connect the power source 21. The time relay 31 is connected to the PLC controller 32 via wires. The PLC controller 32 is connected to the temperature controller 33 via wires. The temperature controller 33 is connected to the upper heating module 51 and the lower heating module 52 via wires. The PLC controller 32 is usually equipped with a touch screen or operation panel, through which parameters such as temperature and time can be set and monitored intuitively, simplifying the operation process.

[0047] Further explanation of this embodiment: Temperature controller 33: Directly connected to the upper heating module 51 and the lower heating module 52 via a guide, it can monitor and adjust the temperature of the heating modules in real time to ensure that the temperature during the welding process is always within the set range; PLC controller 32: Through connection with temperature controller 33, it can realize more complex temperature control logic, such as multi-stage heating, temperature curve control, etc., improving the accuracy and flexibility of temperature control. As a central processing unit, it can integrate multiple control functions, such as temperature control, time control, fault detection, etc., to realize intelligent management of the entire system; Time relay 31: Connected to PLC controller 32, it can set the heating time to realize automated control, reduce manual intervention, and improve production efficiency.

[0048] The thermostat 33 is connected to the heating aluminum plate via a wire.

[0049] The PLC controller 32 is also connected to a reset switch 321 and an alarm 322 via wires. The alarm 322 is connected to the PLC controller 32. When the system detects abnormal temperature, circuit failure, or other situations, the alarm 322 will sound an alarm to remind the operator to take timely measures. The reset switch 321 can transmit a command to the PLC controller 32 to repeat the last set program. The PLC controller 32 controls the time relay 31 and the temperature controller 33 to repeat the process of the last program.

[0050] Reference Figures 2-3 As shown, a second lead screw 63 is rotatably connected to both the front and rear sides of the lower heating module 52 on the control box 1. A third handle 622 is provided on the top of the second lead screw 63. A slide rod 64 is fixedly installed on the control box 1 next to the second lead screw 63. A limiting platform 641 is provided on the top of the slide rod 64. The second lead screw 63 is fixedly connected to the semi-frame platform 61 through a connecting block 613a. The connecting block 613a is threadedly connected to the second lead screw 63 and slidably connected to the slide rod 64. The semi-frame platform 61 includes an upper platform 611, a lower platform 612, and a vertical plate 613. The two ends of the vertical plate 613 are respectively connected to the upper platform 611 and the lower platform 612. The lower platform 612 is connected to the upper platform 611, and the upper platform 611 is threadedly connected to the pressure rod 62. The pressure rod 62 is located between the upper platform 611 and the lower platform 612. One end of the pressure rod 62 is equipped with a pressure block 621, and the other end is equipped with a third handle 622. The vertical plate 613 is connected to the connecting block 613a on the side away from the upper platform 611. The height of the upper and lower platforms 612 of the half-frame platform 61 can be adjusted by the second screw 63 so that the upper surface of the lower platform 612 is flush with the bottom of the tank 522a or the upper surface of the lower heating module 52. Then, the pressure block 621 on the pressure rod 62 presses the rubber rope onto the lower platform 612 to ensure that the position of the rubber rope remains fixed during the welding process.

[0051] Reference Figure 5 As shown, the control box 1 is also equipped with a cutting fixing seat 7. The cutting fixing seat 7 includes a rope seat 71, a third screw 72, and a slider 73. The rope seat 71 is fixedly installed on the control box 1. One end of the rope seat 71 is provided with a stop block 711, and the other end is provided with a connecting platform 712. The slider 73 is slidably connected to the rope seat 71 and is located between the stop block 711 and the connecting platform 712. The third screw 72 is threadedly connected to the connecting platform 712. One end of the third screw 72 passes through the connecting platform 712 and is rotatably connected to the stop block 711. The other end is provided with a fourth handle 721 and is fixedly installed on the control box 1, providing a stable platform to fix the rope to the rope seat 71, which facilitates the cutting of the rope.

[0052] The workflow of this invention is as follows:

[0053] (1) Determine the side length and splicing dimensions of the rubber rope according to the actual installation dimensions of the rubber rope.

[0054] (2) At the joint of the rubber rope that needs to be spliced, the two rubber ropes are flattened and cut out the bevels at the corresponding angles, and the corresponding templates 522 are pre-installed.

[0055] (3) Place the portable hot vulcanizing welding machine horizontally and stably, check whether the wiring of the external power supply 21 is intact, connect the power supply 21, turn on the switch 22, and set the hot vulcanizing temperature and welding time through the PLC controller 32.

[0056] (4) The heating aluminum plate in the lower heating module 52 is powered on and starts to heat up. The temperature of the heating aluminum plate gradually increases. After preheating to the set hot vulcanization temperature, the rubber rope is pressed into the groove 522a of the template 522.

[0057] (5) At the joint of the sloping surface of the rubber rope, fill with raw rubber of the same material as the rubber rope. The amount of filling should be enough to cover the surface of the rubber rope.

[0058] (6) The upper heating module 51 and the lower heating module 52 are closed and locked by the first screw, and high-temperature vulcanization and pressure molding are carried out according to the set welding time.

[0059] (7) Open the upper heating module 51 and the lower heating module 52 through the first screw, take out the fused rubber rope, press the rubber rope to be connected again, fill with raw rubber, close the upper heating module 51 and the lower heating module 52 and lock it, press the reset switch 321, and connect other rubber ropes that need to be fused in sequence for high temperature vulcanization and pressure molding.

[0060] (8) After the rubber rope has been fully vulcanized and pressed, it is flattened again and then installed into the rubber rope installation groove to complete the welding and installation of the rubber rope.
