Constant temperature digital printers in the prior art usually heat the ink cartridge in a relatively cold environment to ensure the normal flow of ink, but this method has obvious disadvantages. On the one hand, the high heating temperature can easily cause the ink to evaporate too quickly, deteriorate or change color, affecting the ink performance.

[0014] The working principle and beneficial effects of the present invention are: The ink tube in the present invention is a channel for conveying ink. In an inkjet digital printer, the ink tube conveys ink from an ink cartridge or ink tank to a nozzle to realize the printing process. The heat preservation tube is sleeved on the ink tube to form a heat preservation cavity between the ink tube and the ink tube. The function of the heat preservation tube is to provide heat preservation for the ink tube to prevent the ink from changing its performance in the ink tube due to temperature changes. In a low temperature environment, the ink will become viscous and affect the smoothness of inkjet; while in a high temperature environment, the ink may deteriorate. The heat preservation tube can maintain the appropriate temperature of the ink by reducing the influence of the external temperature on the ink tube. The temperature control tube is wound around the ink tube and is located in the heat preservation cavity, close to one end of the ink tube. The function of the temperature control tube is to accurately control the temperature of the ink tube. The temperature control tube can adjust the temperature of the ink in the ink tube by heating or cooling to keep it within a constant range. When the temperature of the ink is too low, the temperature control tube can heat the ink tube to increase the temperature of the ink; when the temperature of the ink is too high, the temperature control tube can cool the ink tube to reduce the temperature of the ink.

[0015] The constant temperature inkjet digital printing machine can keep the temperature of the ink in the ink tube constant through the synergistic effect of the insulation tube and the temperature control tube, thereby ensuring the stable performance of the ink. Stable ink performance can ensure the consistency of printing quality and reduce problems such as color deviation and poor ink jetting caused by changes in ink temperature. Constant ink temperature can make the ink spray more uniform at the nozzle, improving the resolution and clarity of printing. At the same time, stable ink performance can also reduce the risk of nozzle clogging and extend the service life of the nozzle. The constant temperature inkjet digital printing machine can work at different ambient temperatures and is not affected by external temperature changes. This allows the printing machine to be used in various occasions, improving the versatility and adaptability of the equipment. Stable ink performance can reduce the risk of nozzle clogging and ink deterioration, and reduce the maintenance cost of the equipment. At the same time, the precise temperature control of the temperature control tube can also reduce energy waste and reduce operating costs.

[0016] In the constant temperature digital printing machine of the prior art, heating is mainly performed at the ink cartridge in a relatively cold environment. This method has some limitations: The heating temperature is high: In order to ensure that the ink can flow and spray normally in a relatively cold environment, the temperature at the ink cartridge needs to be heated to a higher level. However, too high a heating temperature will have an adverse effect on the performance of the ink, such as causing the ink to evaporate too quickly, deteriorate or change color. The prior art mainly focuses on heating in a relatively cold environment, but the control of ink in a high temperature environment is relatively insufficient. In a high temperature environment, the ink may become too thin, affecting the printing quality, or it may easily evaporate and dry up, clogging the nozzle.

[0017] The constant temperature inkjet digital printer in this solution can more effectively maintain the temperature of the ink by arranging a heat preservation tube and a temperature control tube on the ink tube. Compared with the prior art of high temperature heating at the ink cartridge, this solution can reduce the heating temperature. The lower heating temperature can reduce the adverse effects on the ink performance, extend the service life of the ink, and also reduce energy consumption.

[0018] It can not only provide heat preservation function in low temperature environment, but also control the ink in high temperature environment. The temperature control tube can cool or heat the ink tube according to the actual temperature conditions to ensure that the ink is always kept in the appropriate temperature range. This ability to control ink in high temperature environment can improve the adaptability of the printer under different environmental conditions and ensure the stability of printing quality. Through precise temperature control, this solution can make the ink spray more uniform at the nozzle and improve the resolution and clarity of printing. At the same time, stable ink temperature can also reduce the risk of nozzle clogging and improve the reliability and service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] Reference Figure 1 to Figure 9 , is an embodiment of the present invention, and proposes a constant temperature inkjet digital printing machine, including an ink tube 1, a heat preservation tube 2 is sleeved on the ink tube 1, a heat preservation cavity 101 is formed between the ink tube 1 and the heat preservation tube 2, a temperature control tube 3 is wound around the ink tube 1 and is located in the heat preservation cavity 101, and the temperature control tube 3 is located at one end of the ink tube 1.

[0026] In this embodiment, the ink tube 1 is a channel for conveying ink. In an inkjet digital printer, the ink tube 1 conveys ink from the ink cartridge 4 or the ink tank to the nozzle to realize the printing process. The insulation tube 2 is sleeved on the ink tube 1, and a heat preservation chamber 101 is formed between the insulation tube 2 and the ink tube 1. The function of the insulation tube 2 is to provide a heat preservation function for the ink tube 1 to prevent the ink from changing its performance in the ink tube 1 due to temperature changes. In a low temperature environment, the ink will become viscous and affect the smoothness of inkjet; while in a high temperature environment, the ink may deteriorate. The insulation tube 2 can maintain the appropriate temperature of the ink by reducing the influence of the external temperature on the ink tube 1. The temperature control tube 3 is wound around the ink tube 1 and is located in the heat preservation chamber 101, close to one end of the ink tube 1. The function of the temperature control tube 3 is to accurately control the temperature of the ink tube 1. The temperature control tube 3 can adjust the temperature of the ink in the ink tube 1 by heating or cooling to keep it within a constant range. When the temperature of the ink is too low, the temperature control tube 3 can heat the ink tube 1 to increase the temperature of the ink; when the temperature of the ink is too high, the temperature control tube 3 can cool the ink tube 1 to reduce the temperature of the ink.

[0027] The constant temperature inkjet digital printer can keep the temperature of the ink in the ink tube 1 constant through the synergistic effect of the insulation tube 2 and the temperature control tube 3, thereby ensuring the stable performance of the ink. Stable ink performance can ensure the consistency of printing quality and reduce problems such as color deviation and poor ink jetting caused by changes in ink temperature. The constant ink temperature can make the ink spray more uniform at the nozzle, improving the resolution and clarity of printing. At the same time, stable ink performance can also reduce the risk of nozzle clogging and extend the service life of the nozzle. The constant temperature inkjet digital printer can work at different ambient temperatures and is not affected by external temperature changes. This allows the printer to be used in various occasions, improving the versatility and adaptability of the equipment. Stable ink performance can reduce the risk of nozzle clogging and ink deterioration, and reduce the maintenance cost of the equipment. At the same time, the precise temperature control of the temperature control tube 3 can also reduce energy waste and reduce operating costs.

[0028] In the constant temperature digital printing machine of the prior art, heating is mainly performed at the ink cartridge 4 in a relatively cold environment. This method has some limitations: The heating temperature is relatively high: In order to ensure that the ink can flow and spray normally in a relatively cold environment, the temperature at the ink cartridge 4 needs to be heated to a higher level. However, too high a heating temperature will have an adverse effect on the performance of the ink, such as causing the ink to evaporate too quickly, deteriorate or change color. The prior art mainly focuses on heating in a relatively cold environment, but is relatively insufficient for ink control in a high temperature environment. In a high temperature environment, the ink may become too thin, affecting the printing quality, or easily evaporate and dry up, clogging the nozzle.

[0029] The constant temperature inkjet digital printer in this solution can more effectively maintain the temperature of the ink stable by arranging the heat preservation tube 2 and the temperature control tube 3 on the ink tube 1. Compared with the prior art that performs high temperature heating at the ink cartridge 4, this solution can reduce the heating temperature. The lower heating temperature can reduce the adverse effects on the ink performance, extend the service life of the ink, and also reduce energy consumption.

[0030] It can not only provide heat preservation function in low temperature environment, but also control the ink in high temperature environment. The temperature control tube (3) can cool or heat the ink tube 1 according to the actual temperature conditions to ensure that the ink is always kept within the appropriate temperature range. This ability to control the ink in a high temperature environment can improve the adaptability of the printer under different environmental conditions and ensure the stability of the printing quality. Through precise temperature control, this solution can make the ink spray at the nozzle more uniform and improve the resolution and clarity of the printing. At the same time, the stable ink temperature can also reduce the risk of nozzle clogging and improve the reliability and service life of the equipment.

[0031] Furthermore, it also includes an ink cartridge 4, which leads to an ink tube 1, and the ink tube 1 leads to a print head 5. One end of a tank chain 6 is arranged on one side of the ink cartridge 4, and the other end is arranged on one side of the print head 5. The tank chain 6 has an insulation node 601, and the insulation node 601 is arranged in a plurality of rows. The insulation tube 2 is arranged in the insulation node 601.

[0032] In this embodiment, the ink cartridge 4 is a container for storing ink, which leads to the ink tube 1 and provides an ink source for printing. The ink tube 1 leads to the print head 5, which is responsible for spraying ink onto the printing medium to achieve the printing function. One end of the tank chain 6 is arranged on one side of the ink cartridge 4, and the other end is arranged on one side of the print head 5, which plays a role in connecting and protecting lines, pipes, etc. The tank chain 6 has a plurality of insulation joints 601 arranged in an array, and the insulation tube 2 is arranged in the insulation joint 601, so that the tank chain 6 can also participate in the insulation process of the entire system.

[0033] The ink cartridge 4 provides a continuous supply of ink for printing, and the ink tube 1 transports the ink from the ink cartridge 4 to the print head 5 to ensure the smooth progress of the printing process. The tank chain 6 can protect the lines and pipes connecting the ink cartridge 4 and the print head 5 to prevent damage or interference during the operation of the equipment. The setting of the insulation node 601 enables the tank chain 6 to also have an insulation function, further enhancing the insulation effect of the entire system. By fully insulating the ink path, the impact of temperature changes on the ink is reduced, the risk of printing quality problems and equipment failures caused by temperature fluctuations is reduced, and the reliability and stability of the equipment are improved. The setting of the insulation node 601 reduces the impact of strong winds or the outside world of open factories on printing quality.

[0034] Furthermore, it also includes: a limit member 7, the limit member 7 is arranged in the heat preservation chamber 101 and is located on one side of the temperature control tube 3, the heating wire 8 is wound on the ink tube 1 and is located between the limit member 7 and the ink tube 1, the cooling tube 9 is wound on the ink tube 1 and is located between the limit member 7 and the ink tube 1, and is arranged on one side of the heating wire 8, and the thermal insulation member 10 is arranged between the heating wire 8 and the limit member 7, so as to prevent the heating wire 8 from damaging the limit member 7.

[0035] In this embodiment, the stopper 7 is arranged in the heat preservation chamber 101 and is located on one side of the temperature control tube 3. Its function is to limit the position of the heating wire 8 and the cooling tube 9 to ensure that they are accurately installed on the ink tube 1, and also to support and stabilize the structure in the heat preservation chamber 101. The heating wire 8 is wound on the ink tube 1 and is located between the stopper 7 and the ink tube 1. The function of the heating wire 8 is to heat the ink tube 1 when necessary to increase the temperature of the ink and ensure that the ink can still maintain good fluidity and injection performance in a low temperature environment. The cooling tube 9 is wound on the ink tube 1 and is located between the stopper 7 and the ink tube 1 and on one side of the heating wire 8. The function of the cooling tube 9 is to cool the ink tube 1 in a high temperature environment, reduce the temperature of the ink, and prevent the ink from deteriorating or affecting the printing quality due to excessive temperature. The heat insulation member 10 is arranged between the heating wire 8 and the stopper 7. Its main function is to prevent the high temperature generated by the heating wire 8 during operation from damaging the stopper 7. The thermal insulation member 10 can effectively block the transfer of heat, protect the limiting member 7 from being affected by high temperature, and ensure its normal function and service life.

[0036] The combination of the heating wire 8 and the cooling tube 9 enables the constant temperature inkjet digital printer to accurately control the temperature of the ink in the ink tube 1. According to different ambient temperatures and printing requirements, the heating wire 8 or the cooling tube 9 can be flexibly activated to keep the ink within a suitable temperature range, thereby ensuring the stability and consistency of the printing quality. This temperature control method enables the printer to adapt to different working environments and climatic conditions. Whether in cold winter or hot summer, the synergistic effect of the heating wire 8 and the cooling tube 9 can ensure that the performance of the ink is not affected by temperature, thereby improving the adaptability and reliability of the equipment.

[0037] The setting of the thermal insulation member 10 effectively protects the device components such as the stopper 7 from being damaged by the high temperature of the heating wire 8. This not only prolongs the service life of the device components, but also reduces the maintenance cost and failure rate of the device. At the same time, the stabilizing effect of the stopper 7 also helps to ensure that the heating wire 8 and the cooling tube 9 are accurately installed on the ink tube 1, thereby improving the accuracy and effect of temperature control.

[0038] Furthermore, the limiting member 7 is a flexible limiting member 7 .

[0039] In this embodiment, the stopper 7 is a flexible stopper 7. This means that the stopper 7 has a certain flexibility and can be deformed or bent to a certain extent. The flexible stopper 7 can better fit the shape of the ink tube 1, ensuring that the position of the temperature control tube 3 is more tightly and accurately restricted. The ink tube 1 usually has a certain curvature and irregular shape, and the flexible stopper 7 can be adjusted according to the shape of the ink tube 1 to improve the limiting effect. Compared with the rigid stopper 7, the flexible stopper 7 can reduce the friction and damage to the ink tube 1 and the temperature control tube 3 when in contact with them. During the operation of the device, the ink tube 1 and the temperature control tube 3 may vibrate or displace slightly, and the flexible stopper 7 can buffer these movements and reduce the risk of damage. The flexible stopper 7 is usually easier to install and adjust. It can be more easily placed in a suitable position in the insulation chamber 101, and can be adjusted as needed to adapt to different sizes of the ink tube 1 and the temperature control tube 3. This makes the installation and maintenance of the device more convenient and quick. The flexible stopper 7 can better maintain the relative position between the temperature control tube 3 and the ink tube 1, thereby improving the stability of temperature control. It can reduce the movement and shaking of the temperature control tube 3, ensure that the heating wire 8 and the cooling tube 9 can effectively adjust the temperature of the ink tube 1, and improve the printing quality and stability.

[0040] Furthermore, the insulation joint 601 has a cable cavity 602 and an ink tube cavity 603 . The insulation tube 2 is arranged in the ink tube cavity 603 . The cable cavity 602 is used to accommodate the cable, and the ink tube cavity 603 is used to accommodate the insulation tube 2 and the ink tube 1 .

[0041] In this embodiment, the insulation joint 601 has two independent spaces, namely, a cable cavity 602 and an ink tube cavity 603. The cable cavity 602 is specifically used to accommodate cables, ensuring that the cables are protected and arranged in an orderly manner during the operation of the device. The ink tube cavity 603 is used to place the insulation tube 2 and the ink tube 1. The insulation tube 2 is sleeved on the ink tube 1, and the two are located together in the ink tube cavity 603. The ink tube cavity 603 is formed between the insulation tube 2 and the ink tube 1. It provides insulation for the ink tube 1 to ensure that the ink is within a suitable temperature range. The ink tube cavity 603 accommodates the insulation tube 2 and the ink tube 1, and through the effect of the insulation tube 2, the influence of the external temperature on the ink in the ink tube 1 is reduced. The cable cavity 602 and the ink tube cavity 603 of the insulation joint 601 realize functional partitioning, so that the cable and the ink tube 1 each have an independent space. In this way, interference between the cable and the ink tube 1 can be avoided, and the stability and reliability of the device can be improved. The cable will not be affected by the temperature change of the ink tube 1 in the dedicated cable cavity 602, and it is also convenient for the maintenance and management of the cable.

[0042] The existence of the ink tube cavity 603 ensures the thermal insulation effect of the ink tube 1. The ink tube cavity 603 between the insulation tube 2 and the ink tube 1 can effectively block the influence of the external temperature and keep the ink in the ink tube 1 at a constant temperature. This optimized thermal insulation effect helps to improve the performance stability of the ink and ensure the consistency of printing quality. The design of the thermal insulation joint 601 makes full use of the space. The division of the cable cavity 602 and the ink tube cavity 603 enables the equipment to reasonably arrange the cables and the ink tube 1 in a limited space, thereby improving the space utilization rate. At the same time, the formation of the ink tube cavity 603 does not occupy too much additional space, making the equipment more compact. When maintenance or overhaul is required, the structure of the thermal insulation joint 601 enables the cables and the ink tube 1 to be handled separately. The existence of the cable cavity 602 facilitates the inspection and replacement of the cables, while the ink tube cavity 603 facilitates the maintenance of the ink tube 1 and the insulation tube 2. This design improves the maintainability of the equipment and reduces the maintenance cost and time.

[0043] Furthermore, the temperature control tube 3 is located between the tank chain 6 and the print head 5, and a temperature measuring interval 301 is provided between the temperature control tube 3 and the print head 5. The temperature control tube 3 also includes a cable bracket 11, and one end of the cable bracket 11 is provided on the print head 5, and the other end is provided on the tank chain 6, for fixing the cable. One end of the pipe bracket 12 is provided on the print head 5, and the other end is provided on the tank chain 6, for supporting and guiding the insulation tube 2. A fixing part 13 is provided on the pipe bracket 12, and a plurality of fixing parts 13 are arranged in an array. The insulation tube 2 is provided on the fixing part 13. There is at least one temperature measuring part 14, and one temperature measuring part 14 is provided on one fixing part 13. The temperature measuring part 14 has a temperature measuring part 14, and the temperature measuring part 14 is located in the temperature measuring interval 301 and abuts against the ink tube 1.

[0044] In this embodiment, the temperature control tube 3 is located between the tank chain 6 and the print head 5. This position is set to be closer to the print head 5 so as to more accurately control the temperature of the ink that is about to enter the print head 5. There is a temperature measurement interval 301 between the temperature control tube 3 and the print head 5. This interval provides space for the installation and operation of the temperature measuring member 14. One end of the cable bracket 11 is set on the print head 5, and the other end is set on the tank chain 6. Its function is to fix the cable to ensure that the cable will not loosen or entangle during the operation of the equipment, and to ensure the stability of power and signal transmission. One end of the pipeline bracket 12 is set on the print head 5, and the other end is set on the tank chain 6. It is used to support and guide the insulation pipe 2, so that the insulation pipe 2 can be stably connected between the ink cartridge 4 and the print head 5 to ensure the insulation effect. The fixing member 13 is set on the pipeline bracket 12, and is arranged in a plurality of rows. The insulation pipe 2 is set on the fixing member 13, and the fixing member 13 plays a role in fixing the position of the insulation pipe 2 to prevent the insulation pipe 2 from shaking or shifting. There is at least one temperature measuring element 14, and one temperature measuring element 14 is disposed on one fixing element 13. The temperature measuring element 14 has a temperature measuring element 14, and the temperature measuring element 14 is located in the temperature measuring interval 301 and abuts against the ink tube 1. The temperature measuring element 14 is used to measure the temperature of the ink tube 1, so as to timely feed back to the temperature control system to achieve accurate control of the ink temperature.

[0045] The temperature measuring element 14 can accurately measure the temperature of the ink tube 1 by abutting against the ink tube 1. Combined with the function of the temperature control tube 3, the ink temperature can be accurately adjusted according to the temperature measurement result to ensure that the ink is always within a suitable temperature range and improve the printing quality. The cable bracket 11 and the pipe bracket 12 fix the cable and the insulation tube 2 respectively, making the structure of the equipment more stable. The fixing member 13 further enhances the fixing effect of the insulation tube 2 and reduces the influence of the vibration generated by the operation of the equipment on the ink delivery and temperature control. This modular design makes the installation and maintenance of the equipment more convenient. The cable bracket 11, the pipe bracket 12 and the fixing member 13 can be disassembled and replaced separately, which is convenient for repair and maintenance. The setting of the temperature measuring element 14 also makes temperature monitoring more intuitive and convenient, which is convenient for operators to find problems and deal with them in time. Through precise temperature control and stable structural design, the reliability and stability of the equipment are improved. Printing failures caused by temperature fluctuations or loose structures are reduced, and the service life of the equipment is extended.

[0046] Furthermore, the fixing member 13 includes a fixing support 1301, the fixing support 1301 is arranged on the pipeline support 12, the fixing ring 1302 is arranged on the fixing support 1301, the fixing ring 1302 has a fixing notch 1303, and the fixing clamp 1304 is rotatably arranged in the fixing notch 1303. After the fixing clamp 1304 is rotated, the fixing clamp 1304 is clamped in the fixing notch 1303 for fixing the insulation pipe 2.

[0047] In this embodiment, the fixed support 1301 is arranged on the pipeline support 12, serving as the basic support structure of the fixing member 13. It provides an installation position for the fixing ring 1302 and the fixing clamp 1304, and fixes the entire fixing member 13 in a suitable position by connecting with the pipeline support 12. The fixing ring 1302 is arranged on the fixed support 1301. It is usually an annular structure, which is used to surround the insulation pipe 2 and plays a role in preliminarily fixing the insulation pipe 2. The fixing ring 1302 has a fixed notch 1303, which provides space for the installation and operation of the fixing clamp 1304. The fixing clamp 1304 is rotatably arranged in the fixing notch 1303. The fixing clamp 1304 can be rotated in the fixing notch 1303. When the fixing clamp 1304 rotates, it can be clamped in the fixing notch 1303, and work together with the fixing ring 1302 to tightly fix the insulation pipe 2. The design of the fixing member 13 can reliably fix the insulation tube 2 to prevent the insulation tube 2 from shaking, shifting or falling off during the operation of the equipment. The use of the fixing ring 1302 and the fixing clamp 1304 can provide sufficient clamping force to ensure the stable position of the insulation tube 2. The rotating design of the fixing clamp 1304 makes the installation and removal of the insulation tube 2 more convenient. When installing the insulation tube 2, just put the insulation tube 2 into the fixing ring 1302, and then rotate the fixing clamp 1304 so that it is stuck in the fixing notch 1303. When the insulation tube 2 needs to be removed, the fixing clamp 1304 can be rotated in the opposite direction to easily remove the insulation tube 2.

[0048] By replacing the fixing clamps 1304 of different specifications, the insulation tubes 2 of different sizes can be adapted. This flexibility enables the fixing member 13 to be applicable to constant temperature inkjet digital printers of various specifications, thereby improving the versatility of the fixing member 13. The stably fixed insulation tube 2 helps to improve the stability of the entire device. The stable position of the insulation tube 2 can ensure the temperature stability of the ink during the transportation process, thereby improving the printing quality and the reliability of the device.

[0049] Furthermore, the fixing card 1304 has a fixing groove 1305 and a locking hole 1306. The locking hole 1306 is vertically arranged with the fixing groove 1305 and is connected with each other. The fixing notch 1303 has a fixing hole 1307. There are two fixing grooves 1305 and two fixing holes 1307, which are symmetrically arranged along the central axis of the fixing card 1304. After the fixing card 1304 is engaged with the fixing notch 1303, the fixing groove 1305 is connected with the fixing hole 1307. It also includes a sliding member 1308. The sliding member 1308 is slidably arranged in the fixing groove 1305. After the sliding member 1308 slides, it slides into or out of the fixing hole 1307. The pushing member 1309 is slidably arranged in the locking hole 1306. After the pushing member 1309 slides, it is used to push the sliding member 1308 to be clamped into the fixing hole 1307.

[0050] In this embodiment, the fixed card 1304 has a fixed groove 1305 and a locking hole 1306. The fixed groove 1305 is used to accommodate the sliding member 1308, and the locking hole 1306 is vertically arranged with the fixed groove 1305 and communicated with each other, providing a sliding channel for the pusher 1309. The fixed notch 1303 has a fixing hole 1307, and there are two fixed grooves 1305 and two fixed holes 1307, which are symmetrically arranged along the central axis of the fixed card 1304. When the fixed card 1304 is engaged with the fixed notch 1303, the fixed groove 1305 is communicated with the fixed hole 1307. The sliding member 1308 is slidably arranged in the fixed groove 1305. It can slide in the fixed groove 1305, and when the sliding member 1308 slides into the fixing hole 1307, it can enhance the connection stability between the fixed card 1304 and the fixed notch 1303. The pusher 1309 is slidably arranged in the locking hole 1306. The pusher 1309 can slide in the locking hole 1306. When the pusher 1309 slides, it can push the slider 1308 to snap into the fixing hole 1307, so as to further lock the fixing clamp 1304. The design of the slider 1308 and the pusher 1309 further enhances the fixing effect of the fixing clamp 1304 on the insulation pipe 2. When the fixing clamp 1304 is engaged with the fixing notch 1303, the slider 1308 is pushed into the fixing hole 1307 by the pusher 1309, so that the connection between the fixing clamp 1304 and the fixing notch 1303 can be made tighter, so as to prevent the insulation pipe 2 from loosening. The operation of the pusher 1309 is relatively convenient, and it can be operated manually or with tools. Only by sliding the pusher 1309 in the locking hole 1306, the slider 1308 can be pushed, so as to quickly complete the locking of the fixing clamp 1304. This fixing method improves the stability of the insulation pipe 2 on the fixing member 13 and reduces the risk of loosening or displacement of the insulation pipe 2 due to vibration or external force during the operation of the equipment.

[0051] Furthermore, an elastic member 15 is included, and two ends of the elastic member 15 are respectively arranged on the two sliding members 1308 to provide a force for the sliding members 1308 to slide out of the fixing holes 1307 .

[0052] In this embodiment, both ends of the elastic member 15 are respectively arranged on two sliding members 1308. The elastic member 15 can be a member with elastic deformation ability such as a spring. When the insulation tube 2 needs to be removed, the elastic member 15 provides a force for the sliding member 1308 to slide out of the fixing hole 1307. In this way, the fixing card 1304 can be more easily loosened from the fixing notch 1303, which is convenient for the operator to quickly disassemble the insulation tube 2, and improves the efficiency of equipment maintenance and replacement of parts. During the installation or adjustment of the insulation tube 2, if the sliding member 1308 accidentally slides too much into the fixing hole 1307, the elastic force of the elastic member 15 can cause the sliding member 1308 to automatically reset, ensuring that the operation of the fixing card 1304 is smoother and more reliable.

[0053] The presence of the elastic member 15 increases the flexibility of the fixing member 13. It can adapt to size changes and operating errors within a certain range, so that the fixing member 13 can better adapt to different specifications of the insulation pipe 2 and different installation environments. The elastic force of the elastic member 15 can prevent the sliding member 1308 from accidentally sliding too deep into the fixing hole 1307, making it difficult to loosen the fixing clamp 1304, thereby improving the safety of equipment operation and reducing damage or danger that may be caused by improper operation.

[0054] Furthermore, the pushing member 1309 has a first guide bevel 1310, and the sliding member 1308 has a second guide bevel 1311. The first guide bevel 1310 and the second guide bevel 1311 are arranged in abutment with each other. It also includes a pushing bolt 16, and the pushing bolt 16 is threadedly arranged in the locking hole 1306. The pushing member 1309 is rotatably arranged on the pushing bolt 16. After the pushing bolt 16 moves in the locking hole 1306, it drives the pushing member 1309 to slide.

[0055] In this embodiment, the pusher 1309 has a first guide bevel 1310. This bevel is at a specific position of the pusher 1309 and is used to cooperate with the second guide bevel 1311 of the sliding member 1308. The sliding member 1308 has a second guide bevel 1311. When the first guide bevel 1310 and the second guide bevel 1311 are arranged in abutment, the interaction between them can achieve guidance and avoid jamming. The push bolt 16 is threadedly arranged in the locking hole 1306. By rotating the push bolt 16, it can be moved in the locking hole 1306. The pusher 1309 is rotatably arranged on the push bolt 16, and when the push bolt 16 moves, it will drive the pusher 1309 to slide in the locking hole 1306. By rotating the push bolt 16, the sliding distance of the pusher 1309 can be accurately controlled. Since the first guide bevel 1310 of the pusher 1309 abuts against the second guide bevel 1311 of the sliding member 1308, the sliding of the pusher 1309 will be converted into a pushing action on the sliding member 1308, so that the sliding member 1308 accurately slides into or out of the fixing hole 1307, thereby achieving accurate fixation of the insulation pipe 2. The threaded design of the pusher bolt 16 makes the operation more convenient. The operator can lock and loosen the fixed clamp 1304 by rotating the pusher bolt 16, without using complicated tools or operating methods, thereby improving work efficiency. The pusher 1309 is rotatably arranged on the pusher bolt 16, and this connection method can ensure the stability of the pusher 1309 during the sliding process. At the same time, the threaded pusher bolt 16 can also provide reliable force transmission, ensuring that the locking force of the fixed clamp 1304 is large enough, thereby improving the stability of the insulation pipe 2 fixation. This design can adapt to insulation pipes 2 of different sizes and shapes. By adjusting the rotation degree of the push bolt 16, the sliding distance of the pusher 1309 can be controlled to adapt to the insulation pipes 2 of different diameters. At the same time, the design of the guide slope can also adapt to the shape change of the insulation pipe 2 to a certain extent, improving the adaptability of the fixing member 13.
