Description

Technical Field

[0001] This utility model relates to the field of adhesive pretreatment technology, specifically to a circulating water temperature control component for adhesive heating pretreatment. Background Technology

[0002] The process of the extruder acting on the rubber compound: The rubber compound (raw rubber) is originally in a highly elastic state. The feeding mechanism transports the rubber compound into the barrel. The screw shears, heats, and plasticizes the rubber compound, and the heating system of the extruder barrel keeps it at a certain temperature. As the screw rotates and advances, it gradually transforms into a molten state.

[0003] However, during the production process, when the circulating water temperature control component of the extruder heats the water, the water directly passes through the heating cylinder. The water that directly passes through the heating cylinder does not stay in the component for long, which affects the water temperature control. This can easily lead to poor thermoplasticization of the raw rubber sheet, resulting in quality problems in the extrusion of semi-finished parts and affecting product conveying efficiency. To address this, we propose a circulating water temperature control component for rubber material heating pretreatment. Utility Model Content

[0004] This invention provides a circulating water temperature control component for pretreatment of adhesive materials by heating, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a circulating water temperature control component for pretreatment of rubber materials, comprising an extruder body, an extruder barrel and a heating cylinder mounted on the extruder body, a heating circulating water channel forming a closed loop connected between the extruder barrel and the heating cylinder, and a water pump for conveying water installed between the extruder barrel and the heating cylinder, a heating chamber being opened inside the heating cylinder, and multiple partitions being fixedly connected inside the heating chamber, the partitions being staggered and forming a zigzag passage, a spiral heating pipe and a cooling pipe being fixedly connected inside the extruder body, and a rotating and agitating water mixing device being provided at the center of the heating chamber.

[0006] Optionally, the heating circulating water channel is connected to both ends of the heating cylinder and communicates with the heating chamber, and the diameter of the partition is greater than half the diameter of the heating chamber.

[0007] Optionally, a temperature sensor is fixedly connected to the inner wall of the heating chamber, a PLC controller is installed inside the extruder body, the temperature sensor is connected to the PLC controller, and the heating pipe and cooling pipe are connected to the PLC controller.

[0008] Optionally, the heating tube and the cooling tube have the same pitch but different diameters, forming a spiral structure that continuously shrinks and expands, with the mixing device located between the heating tube and the cooling tube.

[0009] Optionally, the mixing device includes a rotating shaft and a stirring plate. The rotating shaft is circularly and movably mounted on the partition plate, and the stirring plate is fixed to the outside of the rotating shaft and located between the partition plates.

[0010] Optionally, the inner wall of the heating chamber is circularly fitted with a toothed disc, and one side of the toothed disc is fixedly connected to multiple connecting columns, one end of which is fixed to one end of the stirring plate.

[0011] Optionally, a gear is connected inside the extruder body via a pin, one side of which meshes with a gear plate, and a motor is fixedly installed on the outside of the extruder body, with the output shaft of the motor connected to the gear.

[0012] This utility model has the following beneficial effects:

[0013] 1. The circulating water temperature control component for preheating the rubber compound, through the structure of the rotating shaft and heating tube, can more effectively control the moisture in the heating chamber. Under the action of the motor, it can extend the path and time of the moisture through the heating chamber, thereby improving the temperature control effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 6 A circulating water temperature control component for pretreatment of rubber compounds includes an extruder body 1, an extruder barrel 2 and a heating cylinder 3 mounted on the extruder body 1, a closed-loop heating circulating water channel 4 connecting the extruder barrel 2 and the heating cylinder 3, and a water pump for water supply installed between the extruder barrel 2 and the heating cylinder 3, thereby enabling water to be circulated. The heating cylinder 3 has a heating chamber inside, and multiple baffles 6 are fixedly connected within the heating chamber. The baffles 6 are staggered and form a zigzag path, allowing the water to circulate. The longer path and time of water through the heating chamber result in better temperature control. The extruder body 1 is internally connected to a spiral heating pipe 8 and a cooling pipe 9, increasing the contact area between the heating pipe 8 and cooling pipe 9 and the water, thus improving temperature control. Furthermore, a rotating mixing device is located at the center of the heating chamber. This device agitates the water, creating a swirling flow that further enhances the contact between the water in the heating chamber and the heating pipe 8 and cooling pipe 9, resulting in even better temperature control.

[0024] Please see Figures 1 to 4 The heating circulating water channel 4 is connected to both ends of the heating cylinder 3 and is connected to the heating chamber. The diameter of the baffle 6 is greater than half the diameter of the heating chamber, so that the baffle 6 can smoothly form a zigzag path.

[0025] Please see Figures 1 to 6A temperature sensor 11 is fixedly connected to the inner wall of the heating chamber. A PLC controller is installed inside the extruder body 1. The temperature sensor 11 is connected to the PLC controller, and the heating pipe 8 and the cooling pipe 9 are also connected to the PLC controller. The temperature sensor 11 can monitor the temperature inside the heating chamber and then transmit a signal to the PLC controller, which then controls the heating pipe 8 or the cooling pipe 9 to heat up or cool down the heating chamber.

[0026] Please see Figures 1 to 6 The heating tube 8 and the cooling tube 9 have the same pitch but different diameters, forming a spiral structure that continuously shrinks and expands. The mixing device is located in the middle of the heating tube 8 and the cooling tube 9, which makes the heating tube 8 and the cooling tube 9 more fully in contact with the water.

[0027] Please see Figures 1 to 6 The mixing device includes a rotating shaft 7 and a stirring plate 10. The rotating shaft 7 is circularly and movably mounted on the partition 6. The rotating shaft 7 can rotate in a fixed position on the partition 6. The stirring plate 10 is fixed on the outside of the rotating shaft 7 and is located between the partitions 6. Driven by the rotation of the rotating shaft 7, the stirring plate 10 can rotate.

[0028] Please see Figures 1 to 6 The inner wall of the heating chamber is circular and movably fitted with a toothed disc 5. Multiple connecting columns 13 are fixedly connected to one side of the toothed disc 5. One end of the connecting column 13 is fixed to one end of the stirring plate 10. Driven by the toothed disc 5, the connecting column 13 can rotate, thereby driving the stirring plate 10 to rotate.

[0029] Please see Figures 1 to 6 A gear 12 is connected inside the extruder body 1 by a shaft pin, so that the gear 12 can rotate in a fixed position on the extruder body 1. One side of the gear 12 meshes with the gear disk 5. Under the drive of the gear 12, the gear disk 5 can rotate. A motor 14 is fixedly installed on the outside of the extruder body 1. The output shaft of the motor 14 is connected to the gear 12. Under the drive of the output shaft of the motor 14, the gear 12 can rotate. The gear 12 is existing technology and will not be described in detail here.

[0030] In summary, this circulating water temperature control component for preheating the adhesive material works by rotating gear 12 under the drive of the output shaft of motor 14. The rotation of gear 12 causes gear disc 5 to rotate, which in turn drives connecting column 13 to rotate, thereby driving rotating shaft 7 to rotate. Rotating shaft 7 then drives stirring plate 10 to rotate, stirring the water in the heating chamber. Guided by partition 6, the path and time of water passing through the heating chamber are extended, resulting in better temperature control. Furthermore, temperature sensor 11 monitors the temperature in the heating chamber and transmits the signal to PLC controller, which then controls heating pipe 8 or cooling pipe 9 to raise or lower the temperature in the heating chamber.
