Description

Technical Field

[0001] This utility model relates to the technical field of polyethylene foam material melting temperature monitoring device, and in particular to a polyethylene foam material melting temperature monitoring device that is easy to maintain. Background Technology

[0002] The melt temperature for low-density polyethylene (LDPE) foaming is typically 105–115°C, while high-density polyethylene (HDPE) requires even higher temperatures (120–135°C). Melt temperature directly affects the viscoelasticity of polyethylene and the decomposition efficiency of the foaming agent. Too low a temperature leads to insufficient melt strength, easy bubble rupture, and the formation of uneven pores; too high a temperature may cause polymer degradation and premature decomposition of the foaming agent, resulting in cell collapse or uneven density. Therefore, real-time monitoring of the melt temperature of polyethylene foam materials is necessary to ensure that the material foams within the optimal temperature range, achieving a uniform cell structure and ideal mechanical properties.

[0003] Currently, in production and use, temperature sensors are often used to monitor the melting temperature of polyethylene foam materials in real time. However, temperature sensors often need to be calibrated and maintained in high-temperature environments and environments where chemical corrosion may occur. Current temperature detection devices are not convenient to maintain. Summary of the Invention

[0004] The purpose of this invention is to provide a convenient-to-maintain polyethylene foam material melting temperature monitoring device to solve the problem mentioned in the background art that current temperature detection devices are not easy to maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient-to-maintain polyethylene foam material melting temperature monitoring device, comprising a device panel and a protective shell. The device panel is provided with an infrared temperature sensing component, a thermocouple component, an alarm component, and a control panel. All of the above components are electrically connected to the control panel. Several connecting shafts are installed on the device panel, and the same linkage rod is connected to the several connecting shafts. The linkage rod is slidably connected to the device panel, and levers are installed on both sides of the linkage rod, which are exposed outside the device panel. Several connecting grooves are provided on the protective shell, and the several connecting grooves are adapted to the several connecting shafts.

[0006] Preferably, each of the connecting shafts is provided with a receiving cavity, and each of the receiving cavities is elastically connected with a contact plate. At the same time, two first ball bearings and two second ball bearings are provided in the receiving cavities.

[0007] Preferably, each of the connecting shafts is provided with a receiving cavity, and each of the receiving cavities is elastically connected with a contact plate. At the same time, two first ball bearings and two second ball bearings are provided in the receiving cavities.

[0008] Preferably, each of the connecting shafts has a connecting hole, the size of which is smaller than the size of the second ball bearing.

[0009] Preferably, each of the contact plates is equipped with an L-shaped connecting rod, and each of the L-shaped connecting rods is connected to a linkage rod.

[0010] Preferably, a first movable groove is provided on each of the connecting shafts, the first movable groove being adapted to the L-shaped connecting rod, and a second movable groove is provided on the device panel, the second movable groove being adapted to the connecting rod.

[0012] The beneficial effects of this utility model are:

[0013] This invention utilizes an infrared temperature sensing component and a thermocouple component to achieve both contact and non-contact temperature monitoring. Users can flexibly switch between these methods depending on their needs. The desired sensing temperature can be set via the control panel. When the monitored temperature is higher or lower than the standard temperature, an alarm component is triggered, prompting staff to quickly identify and respond to the issue. For maintenance, the connecting rod is moved upwards by pushing the lever upwards, releasing the locking relationship between the connecting shaft and the connecting slot, thus allowing for disassembly. For installation, the connecting shaft on the device panel is aligned with the corresponding connecting slot on the protective housing, and the shaft is inserted into the slot. This method is simple to operate, avoiding the need for frequent disassembly and removal of multiple bolts requiring tools during existing maintenance procedures, effectively improving disassembly and assembly efficiency and providing convenience for device maintenance.

[0020] 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.

[0021] Reference Figure 1-5 A convenient-to-maintain polyethylene foam material melting temperature monitoring device includes a device panel 1 and a protective shell 2. The device panel 1 is provided with an infrared temperature sensing component 3, a thermocouple component 4, an alarm component 5, and a control panel 6. All of the above components are electrically connected to the control panel 6. Several connecting shafts 7 are installed on the device panel 1, and the same linkage rod 8 is connected to the several connecting shafts 7. The linkage rod 8 is slidably connected to the device panel 1, and levers 9 are installed on both sides of it. The levers 9 are exposed outside the device panel 1. Several connecting grooves 10 are opened on the protective shell 2, and the several connecting grooves 10 are adapted to the several connecting shafts 7.

[0022] By setting up the infrared temperature sensing component 3 and the thermocouple component 4, both contact and non-contact temperature monitoring methods can be achieved. Users can flexibly switch between them according to their needs. The required sensing temperature can be set through the control panel 6. When the monitored temperature is higher or lower than the standard temperature, the alarm component 5 is triggered to issue an alarm, prompting staff to quickly detect and respond. When maintenance is required, the lever 9 is moved upward to move the connecting rod 8 upward, thereby releasing the locking relationship between the connecting shaft 7 and the connecting groove 10, achieving the purpose of disassembling the device. When the device needs to be installed, the connecting shaft 7 on the device panel 1 is aligned with the corresponding connecting groove 10 on the protective shell 2, and the connecting shaft 7 is inserted into the connecting groove 10 to complete the installation of the device. This method is simple to operate and avoids the need to carry tools and frequently disassemble multiple bolts during existing maintenance, effectively improving the efficiency of disassembly and assembly and providing convenience for the maintenance of the device.

[0023] Specifically, in this embodiment, the infrared temperature sensing component 3, the thermocouple component 4, and the control panel 6 are all modularly distributed on the device panel 1. When any component needs maintenance or replacement, it is convenient for maintenance personnel to directly remove the component that needs maintenance from the device for maintenance without affecting the normal operation of other components.

[0024] Specifically, in this embodiment, several connecting shafts 7 are provided with receiving cavities 11, and several receiving cavities 11 are elastically connected with contact plates 12. At the same time, two first ball bearings 13 and two second ball bearings 14 are provided in the receiving cavities 11, so that the contact plates 12 can apply pressure to the first ball bearings 13 under elastic action, thereby pushing the two second ball bearings 14 to move to the bottom end of the connecting shaft 7 and engage with the connecting groove 10, thereby achieving the purpose of connecting the protective shell 2 and the device panel 1 through the connecting shaft 7.

[0025] Specifically, in this embodiment, several connecting shafts 7 are provided with connecting holes 15. The size of the connecting holes 15 is smaller than the size of the second ball 14, so that when the second ball 14 is pushed by the first ball 13, part of its position will be exposed outside the connecting shaft 7 through the connecting holes 15, thereby enabling the second ball 14 to achieve a connection relationship with the connecting groove 10.

[0026] Specifically, in this embodiment, several contact plates 12 are each equipped with an L-shaped connecting rod 16, and the L-shaped connecting rod 16 is connected to the linkage rod 8. This allows maintenance personnel to move the linkage rod 8 simultaneously and drive the L-shaped connecting rod 16 to move, thereby controlling the position of the contact plate 12 on the connecting shaft 7 by the L-shaped connecting rod 16, thus achieving the rapid completion of the installation or disassembly between the device panel 1 and the protective shell 2.

[0027] Specifically, in this embodiment, a number of connecting shafts 7 are provided with a first moving groove 17, which is adapted to the L-shaped connecting rod 16. The device panel 1 is provided with a second moving groove 18, which is adapted to the connecting rod 8, so that the L-shaped connecting rod 16 can move normally through the first moving groove 17, and the connecting rod 8 can move on the device panel 1 through the second moving groove 18, thereby realizing the connection relationship between the device panel 1 and the protective shell 2 by controlling the connecting rod 8.

[0028] Specifically, in this embodiment, a magnetic layer 19 is provided on the side of the protective shell 2 away from the device panel 1, so that the device can be attached to a metal object through the magnetic layer 19, thereby flexibly placing the device and further improving the flexibility of the device.

[0029] 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.
