Description

Technical Field

[0001] This utility model relates to the field of rubber pretreatment heating technology, and in particular to an adjustable rubber pretreatment heating mechanism. Background Technology

[0002] In the production of semi-finished parts, the rubber compound is often pre-treated by heating using an extruder. The rubber compound (raw rubber) is originally in a highly elastic state. The feeding mechanism conveys the compound into the barrel, where the screw shears, heats, and plasticizes it. The extruder barrel's heating system maintains the compound at a certain temperature, and as the screw rotates, it gradually transforms into a molten state. However, in production, inadequate thermoplasticization of the raw rubber by the extruder can lead to quality problems in the extruded semi-finished parts, affecting product conveying efficiency, stability, and the process control of subsequent steps.

[0003] Current technology directly processes the rubber compound using an extruder without any pretreatment equipment. This leads to issues such as inadequate thermoplasticization of the raw rubber sheet by the extruder, resulting in quality problems in the extruded parts, which affects product quality stability and the process control of subsequent steps. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable rubber pretreatment heating mechanism to solve the problems mentioned in the background art, such as poor thermoplasticization of raw rubber leading to quality problems in the extrusion of semi-finished parts, which affect product conveying efficiency, stability, and process operation control of subsequent processes.

Two connecting plates are mounted opposite each other on the conveying mechanism, and a heating roller is rotatably connected between the two connecting plates. The heating roller is connected to the circulating water temperature control mechanism through a pipeline. A gear tooth is provided on the circumference of the curved surface of one end of the heating roller, and a transmission gear meshes on the gear tooth. A servo motor is connected to the shaft of the transmission gear and is mounted on the connecting plate near the gear tooth. A connecting rod is mounted at the top of the conveying mechanism, and a first temperature detection probe is mounted at the center of the connecting rod. The first temperature detection probe, the servo motor, the circulating water temperature control mechanism, and the conveying mechanism are all integrated on the same PLC control system.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 An adjustable rubber pretreatment heating mechanism includes a support 1, on which a conveying mechanism 2 and a circulating water temperature control mechanism 3 are mounted. Two connecting plates 4 are mounted opposite each other on the conveying mechanism 2, and a heating roller 5 is rotatably connected between the two connecting plates 4. The heating roller 5 is connected to the circulating water temperature control mechanism 3 through a pipeline. A gear tooth 6 is provided on the circumference of the curved surface of one end of the heating roller 5. A transmission gear 7 meshes on the gear tooth 6. A servo motor 8 is connected to the shaft of the transmission gear 7. The servo motor 8 is mounted on the connecting plate 4 near the gear tooth 6. A connecting rod 9 is mounted on the top of the conveying mechanism 2, and a first temperature detection probe 10 is mounted at the center of the connecting rod 9. The first temperature detection probe 10, the servo motor 8, the circulating water temperature control mechanism 3, and the conveying mechanism 2 are all integrated into the same PLC control system.

[0021] When using this device, the rubber material is first placed on the conveying mechanism 2. The rubber material moves through the conveying mechanism 2, while hot water from the circulating water temperature control mechanism 3 is transported to the heating roller 5 through pipelines. When the rubber material is conveyed to the position of the heating roller 5, the heating roller 5 heats up and exchanges heat with the rubber material, thereby achieving the heating treatment of the rubber material. When the rubber material is conveyed to the connecting rod 9, the first temperature detection probe 10 detects the temperature of the rubber material and transmits the detected temperature to the PLC control system. The PLC control system compares the temperature. When the detected temperature is within the standard temperature range, the existing speed of the heating roller 5 is maintained. When the detected temperature is below the standard temperature range, the PLC control system sends an electrical signal to the servo motor 8 to increase the speed of the servo motor 8. This increases the speed of the heating roller 5 through the meshing relationship between the transmission gear 7 and the gear teeth 6, thereby enhancing the heating effect on the rubber material. When the detected temperature is above the standard temperature range, the PLC control system reduces the speed of the servo motor 8, thereby reducing the speed of the heating roller 5 and thus reducing the heating effect of the heating roller 5 on the rubber material, thereby achieving precise control of the required temperature of the rubber material.

[0022] Specifically, in this embodiment, the heating roller 5 is connected to an inlet pipe 11 and an outlet pipe 12 on both sides. The other ends of the inlet pipe 11 and the outlet pipe 12 are connected to the circulating water temperature control mechanism 3, so that the hot water in the circulating water temperature control mechanism 3 can be transported to the heating roller 5 through the inlet pipe 11. When the heat on the heating roller 5 is insufficient, the water in the heating roller 5 can be transported to the circulating water temperature control mechanism 3 through the outlet pipe 12, thereby realizing heat exchange and keeping the heating roller 5 at the required temperature, while achieving water circulation.

[0023] Specifically, in this embodiment, a rotary joint 13 is installed at one end of the water inlet pipe 11 and the water outlet pipe 12 near the heating roller 5. The other end of the rotary joint 13 is connected to the heating roller 5, so that the water inlet pipe 11 and the water outlet pipe 12 can be connected to the heating roller 5 through the rotary joint 13. This ensures that the rotation of the heating roller 5 will not affect the water inlet pipe 11 and the water outlet pipe 12, thus guaranteeing the rotation state of the heating roller 5.

[0024] Specifically, in this embodiment, a water pump 14 is installed on the bracket 1. The water pump 14 is connected to the circulating water temperature control mechanism 3. The start of the water pump 14 enables the heating roller 5 and the water flow in the circulating water temperature control mechanism 3 to exchange through the inlet pipe 11 and the outlet pipe 12.

[0025] Specifically, in this embodiment, the circulating water temperature control mechanism 3 includes a water storage tank 15 installed on the bracket 1. A second temperature detection probe 16 is installed in the water storage tank 15. The second temperature detection probe 16 is electrically connected to the PLC control system, so that the water temperature in the water storage tank 15 can be detected in real time by the second temperature detection probe 16. The detected temperature can be transmitted to the PLC control system, and the PLC control system performs post-processing on the water temperature in the water storage tank 15.

[0026] Specifically, in this embodiment, a heating wire tube 17 is installed inside the water storage tank 15. The heating wire tube 17 is electrically connected to the PLC control system, enabling the PLC control system to send signals to the heating wire tube 17. When the detected temperature is lower than the required temperature, the heating wire tube 17 is controlled to heat the water storage tank 15. When the detected temperature is higher than the required temperature, the heating wire tube 17 is controlled to stop operating, and the temperature inside the water storage tank 15 is reduced through external heat exchange, thereby ensuring that the temperature of the heated circulating water inside the water storage tank 15 is within the standard required range.

[0027] Specifically, in this embodiment, both connecting plates 4 are provided with connecting ports 18. The size of the connecting ports 18 is adapted to the two ends of the heating roller 5, so that the heating roller 5 can be rotatably connected between the two connecting plates 4 through the connecting ports 18, thereby enabling the heating roller 5 to maintain normal rotation on the conveying mechanism 2, thereby achieving the purpose of heating the rubber material.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
