Technical Field

[0001] This utility model relates to the technical field of equipment for processing materials such as rubber and plastics, and in particular to a temperature-controlled experimental open mill. Background Technology

[0002] An open mixing mill is a rubber processing equipment, also known as an open rubber mixing mill or open plastic mixing mill. It mainly consists of two relatively rotating rollers. The rotation of the rollers causes the material to be subjected to compression, shearing, and friction between the rollers, thereby realizing processing operations such as plasticizing, mixing, hot refining, and sheeting of rubber or plastic materials. In the experiment, the processing temperature of the material has a crucial impact on the experimental results.

[0003] Although existing experimental open mills are widely used in material processing, they still have some shortcomings and limitations. For example, existing experimental open mills do not have temperature control functions, making it difficult to meet the processing needs of various materials, which greatly reduces the accuracy and repeatability of experimental data.

[0004] Therefore, a temperature-controlled experimental open mill needs to be designed. Utility Model Content

[0005] In order to overcome the shortcomings of existing experimental open mills that lack temperature control function, making it difficult to meet the processing needs of various materials and greatly reducing the accuracy and repeatability of experimental data, this utility model provides a temperature-controlled experimental open mill.

[0006] The technical solution is as follows: A temperature-controlled experimental open mill includes a support frame, a controller, open mill rolls, a drive shaft, heat pipes, a first heat storage cylinder, a second heat storage cylinder, a fixed plate, an input pipe, a one-way valve, a circulating water outlet pipe, a heating water tank, a temperature-controlled heater, a reduction motor, and a transmission gear set. The controller is installed on the front side of the support frame. Two open mill rolls are rotatably connected between the left and right sides of the upper end of the support frame. A drive shaft is fixedly connected inside each of the two open mill rolls, passing through the rolls on both sides and rotatably connected to the support frame. Multiple heat pipes are fixedly connected inside each open mill roll, passing through the rolls at both ends. A symmetrically distributed fixed plate is fixedly connected to both sides of the two drive shafts. The multiple heat pipes inside each open mill roll are fixedly connected to the two fixed plates at both ends. On the left side, two fixed plates are rotatably connected to heat storage cylinder one, and on the right side, two fixed plates are rotatably connected to heat storage cylinder two. An input pipe is fixedly connected to the lower end of each of the two heat storage cylinders, and a one-way valve is installed on each of the two input pipes. A circulating water outlet pipe is fixedly connected to the lower end of each of the two heat storage cylinder two. A heating water tank is fixedly connected to the bottom of the support frame. The lower ends of the two input pipes are connected to the left side of the heating water tank, and the lower ends of the two circulating water outlet pipes are connected to the right side of the heating water tank. A temperature-controlled heater is installed on the front of the heating water tank, and the temperature-controlled heater is electrically connected to the controller. A symmetrically distributed transmission gear set is connected between two transmission shafts on the same side. Gear motors are installed on both sides of the support frame, and both gear motors are electrically connected to the controller. The output shafts of the gear motors are connected to the transmission gear sets.

[0007] Optionally, it also includes a corrugated rotating shaft, a moving ring, a follower block, a connecting plate, and a piston ring. The left side of each of the two drive shafts is fixedly connected to a corrugated rotating shaft. The outside of each of the two corrugated rotating shafts is slidably connected to a moving ring. The upper inside of each of the two moving rings is fixedly connected to a follower block. Each follower block is in contact with the corresponding corrugated rotating shaft.

This solves the problem that the existing experimental open mill does not have a temperature control function, which makes it difficult to meet the processing needs of various materials and greatly reduces the accuracy and repeatability of experimental data.

[0013] 2. This utility model, by setting up a corrugated rotating shaft, a moving ring, a follower block, a connecting plate, and a piston ring, allows the rotating shaft to rotate, causing the follower block to move along the corrugated trajectory of the rotating shaft. This, in turn, causes the moving ring to reciprocate left and right on the transmission shaft. The movement of the moving ring, through the connecting plate, causes the piston ring to reciprocate left and right simultaneously within the first heat storage tank, thus realizing the circulation of hot water between the first and second heat storage tanks. This reduces energy consumption, improves energy utilization, and saves operating costs. Attached Figure Description

The controller 101 is mounted on the front of the support frame 1. Two open mill rolls 2, symmetrically distributed front to back, are rotatably connected between the left and right sides of the upper end of the support frame 1. The open mill rolls 2 are made of high-quality carbon structural steel, possessing high strength and good casting performance. Each roller 2 has a drive shaft 3 welded inside. The drive shaft 3 passes through both sides of the open mill roller 2 and is rotatably connected to the support frame 1. Multiple heat-conducting pipes 4 are welded inside each open mill roller 2. The heat-conducting pipes 4 are made of stainless steel 321, possessing excellent high-temperature resistance and corrosion resistance, enabling long-term stable operation in high-temperature environments. Both ends of the heat-conducting pipes 4 pass through the open mill roller 2. Symmetrically distributed fixing plates 502 are welded to both sides of each of the two drive shafts 3. The multiple heat-conducting pipes 4 inside each open mill roller 2 are welded to the fixing plates 502 at both ends. Rotary... A heat storage cylinder 5 is movably connected to the support frame 1. Two heat storage cylinders 501 are rotatably connected to the two fixed plates 502 on the right side. Inlet pipes 6 are welded to the lower ends of both heat storage cylinders 5, and one-way valves 7 are installed on both inlet pipes 6 to ensure that hot water can only flow into the corresponding heat storage cylinder 5 in one direction, preventing backflow. Circulation outlet pipes 8 are welded to the lower ends of both heat storage cylinders 501. A heating water tank 9 is welded to the bottom of the support frame 1. The lower ends of both inlet pipes 6 are connected to the left side of the heating water tank 9, and the lower ends of both circulation outlet pipes 8 are connected to the right side of the heating water tank 9. A temperature-controlled heating element is installed on the front of the heating water tank 9. The device 10, the temperature control heater 10, is electrically connected to the controller 101. It can monitor the water temperature in real time and automatically adjust the heating power according to the difference between the temperature set by the controller 101 and the actual water temperature to ensure that the hot water flowing into the open mill roll 2 has a stable temperature and achieve precise control of the temperature of the open mill roll 2. The two drive shafts 3 on the same side are connected by a drive gear set 12 that is symmetrically distributed on the left and right. The support frame 1 is equipped with a geared motor 11 on both the left and right sides. The geared motor 11 is electrically connected to the controller 101 and the output shaft of the geared motor 11 is connected to the drive gear set 12.

[0021] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it also includes a corrugated rotating shaft 13, a moving ring 14, a follower block 15, a connecting plate 16, and a piston ring 17. Corrugated rotating shafts 13 are welded to the left side of both transmission shafts 3. Corrugated tracks are opened on both corrugated rotating shafts 13. Moving rings 14 are slidably connected to the outside of both corrugated rotating shafts 13. Follower blocks 15 are welded to the upper inside of both moving rings 14. Both follower blocks 15 are in contact with the corresponding corrugated rotating shafts 13. Connecting plates 16 are symmetrically distributed on the front and rear sides of both moving rings 14. Piston rings 17 are welded between every two connecting plates 16. Both piston rings 17 are slidably connected to the inside of the corresponding heat storage cylinder 5. The connecting plates 16 are slidably connected to the heat storage cylinder 5.

[0022] like Figure 1 As shown, it also includes a collection frame 18, which is slidably connected to the top of the support frame 1 for collecting the processed materials.

[0023] When this device is needed, the geared motor 11 and the temperature-controlled heater 10 are first started by the controller 101. The output shaft of the geared motor 11 rotates, driving the transmission gear set 12 to rotate, which in turn drives the two open mill rolls 2 to rotate relative to each other through the transmission shaft 3. The temperature-controlled heater 10 starts to heat the water in the heating tank 9. After heating is completed, the one-way valve 7 is opened, and the heated hot water flows into the heat storage cylinder 5 through the input pipe 6. As the transmission shaft 3 rotates, the corrugated rotating shaft 13 rotates accordingly, driving the follower block 15 to move along the corrugated trajectory of the corrugated rotating shaft 13, thereby driving the moving ring 14 to reciprocate left and right on the transmission shaft 3. The movement of the moving ring 14 will drive the piston ring 17 to reciprocate left and right in the heat storage cylinder 5 through the connecting plate 16. When the piston ring 17 moves to the left, it pushes the hot water in the heat storage cylinder 5 into the heat conduction pipe 4 through the heat conduction pipe 4. The heat conduction pipe 4 heats the hot water. The water temperature is transferred to the open mill roll 2, causing it to rise. The temperature control heater 10 can monitor the water temperature in real time and automatically adjust the heating power according to the difference between the temperature set by the controller 101 and the actual water temperature. When the piston ring 17 moves to the right, the water cooled by the open mill roll 2 is drawn into the heat storage cylinder 501 and flows back into the heating water tank 9 through the circulation outlet pipe 8. This achieves the circulation of hot water between the heat storage cylinder 5 and the heat storage cylinder 501. The material to be processed can be placed between the two open mill rolls 2. Under the squeezing and friction of the open mill rolls 2, the material is continuously mixed and plasticized. After processing, the material is peeled off from the open mill roll 2 and falls into the collection frame 18 for collection. After use, the one-way valve 7, the reduction motor 11 and the temperature control heater 10 are closed, the collection frame 18 is removed, and the processed material is collected, thus completing the use of this device.
