Description

Technical Field

[0001] This invention belongs to the field of temperature measurement technology, and specifically relates to a temperature measurement module for a film transfer cooling device. Background Technology

[0002] In the production of medical rubber stoppers, after the raw materials are mixed, they are fed into a tableting machine for extrusion and tableting to form a film. Because the rubber is heated during extrusion and tableting, the film needs to be cooled promptly after exiting the tableting machine to ensure film quality and meet subsequent vulcanization requirements. The cooling process of the film is usually carried out in a film transfer cooling device. To ensure the cooling effect, a temperature measuring module, a cooling module, and a control module are typically installed in the film transfer cooling device. The control module can control the airflow speed and temperature of the cooling air in real time based on the film temperature measured by the temperature measuring module, ensuring that the film reaches the predetermined temperature after exiting the machine, thus guaranteeing the cooling efficiency and effect.

[0003] In existing technology, film transfer cooling equipment has an inlet and an outlet, and multiple rotating rollers are installed between the inlet and outlet (within the internal space of the film transfer cooling equipment). Each roller causes the film entering through the inlet to be wound in a serpentine pattern and exited through the outlet. To ensure timely temperature measurement of the film, at least three temperature measuring structures are usually installed during the film transfer process. These structures are spaced apart along the film's transmission path. However, each temperature measuring structure is an infrared temperature sensor installed in the film transfer cooling equipment. Because the infrared temperature sensor cannot contact the film and is affected by environmental factors (the airflow temperature within the internal space of the film transfer cooling equipment), the data measured by the infrared temperature sensor is inaccurate, resulting in poor temperature measurement performance and limited practicality. Summary of the Invention

[0004] This invention provides a temperature measurement module for film transfer cooling equipment, which aims to solve the problem of poor practicality caused by the poor temperature measurement effect of existing temperature measurement modules used in film transfer cooling equipment.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A temperature measurement module for a film transfer cooling device is provided, comprising multiple temperature measurement units and a matching controller; each temperature measurement unit is spaced apart along the film transfer path; a horizontal direction perpendicular to the film transfer direction is defined as the first direction; each temperature measurement unit includes a mounting plate, a roller structure, and a temperature measurement structure; two mounting plates are provided, both fixed in the internal space of the film transfer cooling device along the film transfer direction, and the two mounting plates are respectively located on both sides of the film; two roller structures are provided, each corresponding to one of the two mounting plates, and each... Each roller structure includes multiple rollers, which are spaced apart along the first direction and rotatably mounted on a corresponding mounting plate. The outer edge of each roller rolls into contact with the film transmitted between the two mounting plates.

Each temperature measuring structure includes multiple temperature measuring elements, which are fixed on the corresponding mounting plate and correspond one-to-one with each roller. Each temperature measuring element has a temperature measuring end, which rolls into contact with the outer edge of the corresponding roller to measure the temperature of the roller.

[0007] The mounting plate is provided with a sliding cavity for the sliding seat to slide.

[0008] In one possible implementation, the rolling wheel is rotatably disposed within the sliding cavity.

[0009] In one possible implementation, the temperature measuring element further includes a fixed cylinder and a spring; the fixed cylinder is located on the side of the mounting plate away from the film and is detachably connected to the mounting plate; the fixed cylinder has a cavity for housing the sliding seat and the temperature sensor; the spring is disposed in the cavity, one end of the spring abuts against the bottom wall of the cavity, and the other end abuts against the sliding seat, the spring being used to spring the sliding seat to maintain a tendency to move towards the rolling wheel, so that the detection end of the temperature sensor remains in contact with the rolling wheel.

The roller structures on the two mounting plates of each temperature measuring unit can simultaneously contact both sides of the film, ensuring simultaneous temperature measurement on both sides of the film, thus guaranteeing the accuracy of temperature detection. Furthermore, the multiple rollers on each mounting plate increase the temperature detection area of ​​the film across its width, further ensuring the film temperature detection effect. In addition, the rollers rotate with the movement of the film, promptly transferring the film's temperature to the measuring element, greatly reducing the impact of environmental factors on temperature detection. The temperature measurement module for the film transfer cooling equipment provided in this embodiment effectively ensures the accuracy of film temperature measurement, guarantees measurement results, and is highly practical.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] Please refer to the following: Figure 1 and Figure 2 The temperature measurement module for the film transfer cooling device provided by the present invention will now be described. The temperature measurement module for the film transfer cooling device includes multiple temperature measurement units and a matching controller. Each temperature measurement unit is spaced apart along the transfer path of the film 40. The horizontal direction perpendicular to the transfer direction of the film 40 is defined as the first direction. Each temperature measurement unit includes a mounting plate 10, a roller structure 20, and a temperature measurement structure 30. Two mounting plates 10 are provided, both fixed in the internal space of the film transfer cooling device along the transfer direction of the film 40, and located on opposite sides of the film 40. Two roller structures 20 are provided, each corresponding to one of the two mounting plates 10. Each roller structure 20 includes multiple rolling wheels 21, spaced apart along the first direction, and each rolling wheel 21 is rotatably mounted on its corresponding mounting plate 10. The outer edge of each rolling wheel 21 rolls and abuts against the film 40 transferred between the two mounting plates 10. There are two temperature measuring structures 30, which are respectively set one-to-one with two mounting plates 10. Each temperature measuring structure 30 includes multiple temperature measuring elements, each of which is fixed on the corresponding mounting plate 10 and corresponds one-to-one with each rolling wheel 21. Each temperature measuring element has a temperature measuring end, which can roll and contact the outer edge of the corresponding rolling wheel 21 to measure the temperature of the rolling wheel 21.

[0020] The temperature measurement module for the film transfer cooling device provided in this embodiment works as follows: multiple temperature measuring units measure the temperature of the film 40 in segments during the film transfer process and transmit the temperature information to the controller. The controller then controls the cooling module to optimize the cooling operation. In each temperature measuring unit, two temperature measuring structures 30 are located on both sides of the film 40 and contact the film 40 through rolling wheels 21. The rolling wheels 21 rotate as the film 40 moves, thereby transferring the heat from its surface to the temperature measuring element in a timely manner (no longer affected by environmental factors), and the temperature measuring element promptly detects the temperature.

[0021] Compared with existing technologies, the temperature measurement module for the film transfer cooling device provided in this embodiment allows multiple temperature measurement units to detect the temperature of the film 40 in segments during the film transfer process, thereby ensuring the provision of temperature data to the cooling module and guaranteeing the cooling effect and efficiency. The roller structures 20 respectively provided on the two mounting plates 10 in each temperature measurement unit can simultaneously abut against both sides of the film 40, ensuring simultaneous temperature measurement on both sides of the film 40, thus guaranteeing the accuracy of temperature detection. Furthermore, the multiple rollers on each mounting plate 10 increase the temperature detection area of ​​the film 40 in the width direction, further ensuring the temperature detection effect of the film 40. In addition, the rolling wheels 21 rotate with the movement of the film 40, promptly transferring the temperature of the film 40 to the temperature measuring element, greatly reducing the impact of environmental factors on temperature detection. The temperature measurement module for the film transfer cooling device provided in this embodiment effectively guarantees the accuracy of film 40 temperature measurement, while also ensuring measurement effect, and is highly practical.

[0022] It should be noted that the two mounting plates 10 can be connected by a lifting adjustment mechanism to drive the two mounting plates 10 to move in opposite directions or relative to each other, so as to accommodate films 40 of different thicknesses. The lifting adjustment mechanism can be a worm gear structure, which is existing technology and will not be described in detail here.

[0023] In some embodiments, the temperature sensing element described above can be as follows: Figure 1 The structure shown. See also Figure 1 Each temperature sensing element includes a sliding base 31 and a temperature sensor 32. The sliding base 31 is slidably mounted on the mounting plate 10 along the vertical direction, and has a vertically penetrating cavity. The temperature sensor 32 is fixed in the cavity and has a sensing end. The sensing end of the temperature sensor 32 slides in contact with the outer peripheral surface of the roller 21, and the temperature sensor 32 is electrically connected to the controller. The sliding base 31 ensures the fixed installation of the temperature sensor 32 and also ensures stable installation with the mounting plate 10. The sliding connection with the mounting plate 10 ensures that the sensing end of the temperature sensor 32 can contact the outer peripheral surface of the roller 21, thereby ensuring the temperature detection effect and making it highly practical.

[0024] The mounting plate 10 is provided with a sliding cavity 11 for the sliding seat 31 to slide, and the sliding cavity 11 can ensure the stable placement of the sliding seat 31.

[0025] In this embodiment, the detection end of the temperature sensor 32 is the temperature measuring end of the temperature sensing element. The temperature sensor 32 can be a contact temperature sensor, such as a thermistor. A copper metal layer 22 can be radiated at the detection end of the temperature sensor 32 to increase wear resistance.

[0026] In some embodiments, the aforementioned roller 21 may be as follows: Figure 1 The structure shown. See also Figure 1 The rolling wheel 21 is rotatably disposed in the sliding cavity 11.

[0027] It should be noted that the sliding cavity 11 must penetrate the mounting plate 10 in a vertical direction to ensure that the outer edge of the rolling wheel 21 can extend out of the mounting plate 10.

[0028] In some embodiments, the temperature sensing element described above can be as follows: Figure 1 The structure shown. See also Figure 1 The temperature measuring element also includes a fixed cylinder 33 and a spring 34. The fixed cylinder 33 is located on the side of the mounting plate 10 away from the film 40 and is detachably connected to the mounting plate 10. The fixed cylinder 33 has a cavity 331, which can enclose the sliding seat 31 and the temperature sensor 32. The spring 34 is disposed in the cavity 331, with one end abutting against the bottom wall of the cavity 331 and the other end abutting against the sliding seat 31. The spring 34 can spring the sliding seat 31 to maintain a tendency to move towards the rolling wheel 21, so that the detection end of the temperature sensor 32 remains in contact with the rolling wheel 21. The fixed cylinder 33 can protect the sliding seat 31 and the temperature sensor 32, and at the same time, the fixed cylinder can also provide a space for the spring 34 to be installed. By springing the sliding seat 31 to slide, it can be ensured that the detection end of the temperature sensor 32 continuously abuts against the outer edge of the rolling wheel 21, thereby ensuring timely detection of the temperature of the film 40, which is highly practical.

[0029] In some embodiments, the aforementioned fixed cylinder 33 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 The fixed cylinder 33 and the mounting plate 10 are connected by threads. The mounting plate 10 has threaded holes on its corresponding surface that are threaded to the fixed cylinder 33. The threaded holes ensure easy connection of the fixed cylinder 33, which in turn ensures easy installation of the temperature sensor 32 with the sliding seat 31. It also ensures easy disassembly and assembly during subsequent maintenance, making it highly practical.

[0030] In this embodiment, the threaded hole can be a threaded annular groove, and an external thread structure is provided on the inner wall surface of the threaded annular groove. The corresponding side wall of the cavity 331 of the fixed cylinder 33 is provided with its matching internal thread structure.

[0031] In some embodiments, the aforementioned fixed cylinder 33 may be adopted as follows: Figure 1 The structure shown. See also Figure 1The fixed cylinder 33 has a wiring hole 35 at the end away from the mounting plate 10. The wiring hole 35 is connected to the cylinder cavity 331. Since the electrical connection between the temperature sensor 32 and the controller requires an electrical connection wire, the wiring hole 35 can ensure the passage of the electrical connection wire, thereby ensuring the electrical connection effect of each temperature sensor 32.

[0032] In some embodiments, the aforementioned roller 21 may be as follows: Figure 2 The structure shown. See also Figure 2 Each rolling wheel 21 has a copper metal layer 22 on its outer edge. Copper has a strong thermal conductivity, which ensures that the heat on the film 40 is transferred to the temperature sensor 32 in a timely manner, thereby ensuring the accuracy of the temperature sensor 32 in measuring the temperature of the film 40.

[0033] In some embodiments, one temperature measuring unit is located at the inlet of the film 40 transfer cooling device, and another temperature measuring unit is located at the outlet of the film 40 transfer cooling device. This structure can ensure the monitoring of the temperature of the incoming film 40 and the temperature of the outgoing film 40, thereby ensuring the cooling effect of the film 40, and also facilitates the controller to command the cooling module to work accurately.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
