Description

Technical Field

[0001] The invention relates to the technical field of laser printing, in particular to a heat recovery device for laser printing equipment and a heat recovery method thereof. Background Art

[0002] When a laser printer is in use, the material is heated by a heating block to make it semi-liquid and then ejected through a nozzle. During the heating process, the material cannot be overheated, otherwise the material will be liquid, which is not conducive to product molding. If the heating is insufficient, the material cannot be ejected smoothly, which is not conducive to product molding. The heating block generates a lot of heat when heating the material, and this excess heat is generally directly dissipated and discharged through a cooling fan, which will cause a lot of heat waste.

[0010] A second motor is also fixedly connected inside the moving frame, and a rotating disk is fixedly connected to the end of the main shaft of the second motor, and a vertically arranged heat insulator is fixedly connected to the top of the rotating disk;

[0011] The inside of the side frame is also fixedly connected to a first motor arranged transversely, the end of the main shaft of the first motor is fixedly connected to a threaded shaft, the other end of the threaded shaft is rotatably connected to the side frame, the outer side of the threaded shaft is spirally connected to two groups of threaded sleeves, and the outer side of the threaded sleeve is fixedly connected to a sliding plate, the top of the sliding plate is fixedly connected to the moving frame, and the bottom of the sliding plate is slidably connected to the side frame;

[0012] A water leakage detection module is also installed on one side of the bottom of the installation frame.

[0014] A vertically arranged blocking plate is fixedly connected to the upper inner part of the side frame, and the blocking plate is located at one side of the moving frame.

[0015] As an optional solution of the heat recovery device and recovery method for laser printing equipment described in the present invention, the preheating frame and the heat insulator are both arranged in a vertical semi-cylindrical shape, and the outer diameter of the heat insulator is smaller than the inner diameter of the preheating frame.

[0016] As an optional solution of the heat recovery device and the heat recovery method for laser printing equipment described in the present invention, a first solenoid valve is installed on the outside of the first water pipe, and a second solenoid valve is installed on the outside of the fourth water pipe.

[0017] When the laser printer is in use, the material is heated by the heating block to make it semi-liquid, and then ejected through the nozzle. During the heating process, the material cannot be overheated, otherwise the material will be liquid, which is not conducive to product molding. If the heating is insufficient, the material will not be ejected smoothly, which is not conducive to product molding. The heating block generates a lot of heat when heating the material, and this excess heat is generally directly dissipated through the cooling fan, which will cause a lot of heat waste. When the device is in use, a layer of heat recovery pipe is surrounded on the outside of the radiator. The circulating pump drives the cooling liquid to circulate slowly inside the heat recovery pipe and cooperates with the radiator to achieve thermal exchange. In this case, heat can be recovered, and when this part of the heat flows through the preheating frame and the preheating frame is close to the material extrusion tube, the material inside the material extrusion tube can be preheated, which not only ensures the heating and molding quality of the material, but also reduces the burden on the heating block. After the traditional preheating of the material inside the material box, once the material is not completely used, it is easy to stick to the extrusion tube and the inner wall of the material box, which is not easy to clean and is easy to be blocked during subsequent use. The preheating method of the material inside the material extrusion tube through the preheating frame can achieve local preheating, which is not easy to occur. Even if the material is not used up, the material is still in a dry state. When printing is about to be completed, Its preheating mechanism is evacuated, and the subsequent materials continue to be transported. At this time, the cleaning work of the material extrusion tube can be completed to ensure that the device can be used normally later. When preheating the material inside the material extrusion tube, the threaded shaft can be driven to rotate by starting the side frame, and the threaded shaft drives the outer threaded sleeve to move, and drives the sliding plate and the moving frame to move. At this time, the moving frame can drive the upper preheating frame to approach the material extrusion tube, thereby realizing the preheating of the material inside the material extrusion tube, and when preheating the material extrusion tube, by starting the second motor, the second motor can drive the rotating disk to rotate, and the rotating disk drives the upper insulation body to rotate. At this time, the preheating frame and the insulation body form a circular cylindrical shape. Structure, at this time, it can be surrounded by the outside of the material extrusion tube, and the heat insulator can cooperate with the preheating frame to prevent heat from being dissipated and lost to the surroundings. This arrangement greatly reduces heat waste, so that its heat can be used to preheat the material extrusion tube in a targeted manner to ensure the preheating quality; after the printing work is about to be completed, it can be away from the material extrusion tube in advance through the preheating frame to ensure that the material inside the material extrusion tube is solid and the material is fully discharged, and when the preheating frame is away from the material extrusion tube, it drives the rotating disk to rotate through the second motor, so that the heat insulator rotates to the inside of the preheating frame, which is convenient for the preheating frame to evacuate smoothly, and the heat insulator serves the purpose of insulation to prevent the preheating frame from continuing to preheat the material extrusion tube.

[0018] As an optional solution of the heat recovery device and the heat recovery method for laser printing equipment described in the present invention, wherein: the outer sides of the fourth water pipe and the first water pipe are both connected to a heat dissipation module, the heat dissipation module includes a first connecting pipe, a second hose and a heat exchanger, one end of the first connecting pipe is connected to the fourth water pipe, the other side of the first connecting pipe is connected to the fourth hose, and the other end of the fourth hose is connected to the heat exchange pipe, the other end of the heat exchange pipe is connected to the third hose, and the other end of the third hose is connected to the heat exchanger, the other end of the heat exchanger is connected to the second hose, the other end of the second hose is connected to the second connecting pipe, and the other end of the second connecting pipe is connected to the first water pipe;

[0019] A third solenoid valve is installed on the outer side of the second communicating pipe, and a fourth solenoid valve is installed on the outer side of the first communicating pipe.

[0020] As an optional solution of the heat recovery device and recovery method for laser printing equipment described in the present invention, the outer side of the first connecting tube and the outer side of the second connecting tube are both slidably connected with guide rings, and the outer sides of the guide rings are both fixedly connected with fixed plates, and the outer side of the fixed plate is fixedly connected to the moving module.

[0021] During actual use, the coolant for heat exchange passes through the circulation pump at high temperature for a long time, and the circulation pump is in a high-temperature working state for a long time, which may cause certain damage to the circulation pump. At this time, the first connecting pipe and the second connecting pipe are connected in parallel to the fourth water pipe and the outside of the first water pipe, and the second solenoid valve on the outside of the fourth water pipe and the first solenoid valve on the outside of the first water pipe are closed, and then the fourth solenoid valve on the outside of the first connecting pipe and the third solenoid valve on the outside of the second connecting pipe are opened. At this time, the circulation pump can be used to drive the flow of liquid inside the first connecting pipe and the second connecting pipe, and the heat exchange tube is located inside the control module. The liquid is cooled when passing through the inside of the third hose. At this time, not only can the internal temperature of the circulation pump be reduced to ensure the normal use of the circulation pump, but the coolant can also cool the inside of the control module through the heat exchange tube to ensure the normal use of the components inside the control module.

[0022] As an optional solution of the heat recovery device and recovery method for laser printing equipment described in the present invention, the water leakage detection module includes a water collecting tank, a groove and a water leakage detector, the top of the water collecting tank is fixedly connected to the heat recovery module, a strip-shaped groove is opened inside the water collecting tank, and a water leakage detector fixedly connected to the water collecting tank is installed inside the groove, and a drain plug is also installed on the outside of the water collecting tank.

[0023] As an optional solution of the heat recovery device and the heat recovery method for laser printing equipment described in the present invention, the front and rear inner walls of the water collecting tank are arranged in inclined surfaces.

[0024] When heat recovery is carried out, since heat is recovered through water, a water collecting tank is set at the bottom of the installation frame. Once water leakage occurs, the water will drip into the water collecting tank and gather in the groove. It can be monitored by a water leakage detector and an external alarm unit can be used to give a reminder, so that people can deal with it in time.

[0025] As an optional solution of the heat recovery device and the recovery method for laser printing equipment described in the present invention, the recovery method steps of the device are as follows:

[0026] Step 1: When the printer is started, its heating block is used to heat the material to make it semi-liquid. At this time, the temperature of the heating block is very high. When the heat of the printer's heating block is recovered, the spirally arranged heat recovery pipe is used to cooperate with the radiator to recover the heat through the flowing coolant, and the power of the liquid flow is provided by the circulation pump;

[0027] Step 2: When the coolant spirally flows through the heat recovery pipe, it exchanges heat. At this time, the heated liquid enters the preheating frame through the fourth water pipe and the moving frame. At this time, the preheating frame can preheat the material inside the material extrusion pipe;

[0028] Step 3: During the preheating process of the material extrusion tube, the second motor drives the rotating disk to rotate, and the rotating disk drives the heat insulator to rotate so that the heat insulator is located on the opposite side of the preheating frame. At this time, the heat insulator and the preheating frame form a hollow cylinder to surround the material extrusion tube for preheating;

[0029] Step 4: When the printing work is about to be completed, the heat insulator rotates to the inside of the preheating frame, and the first motor is started to drive the threaded shaft to rotate, thereby driving the threaded sleeve and the sliding plate to move, and finally driving the moving frame and the preheating frame away from the material extrusion tube. At this time, the material extrusion tube will not continue to be preheated;

[0030] Step 5: The heat dissipation module is connected in parallel to the outside of the first water pipe and the fourth water pipe of the circulation pump. When the first solenoid valve and the second solenoid valve are closed, the third solenoid valve and the fourth solenoid valve are opened, and the circulation pump drives the coolant to enter the heat exchange tube through the first connecting pipe, and the heat exchange tube is arranged inside the control module to achieve heat dissipation inside the control module;

[0031] Step 6: In actual use, the water collection tank is used to collect leaked water and is monitored by a water leakage detector. Once a leak occurs, an external alarm will be used to warn you, facilitating timely processing.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] When the present invention is in use, a layer of heat recovery pipe is surrounded on the outside of the radiator, and the cooling liquid is driven by the circulation pump to slowly circulate in the heat recovery pipe and cooperate with the radiator to achieve heat exchange, so that heat recovery can be achieved. When this part of heat flows through the preheating frame and the preheating frame is close to the material extrusion pipe, the material inside the material extrusion pipe can be preheated, which not only ensures the heating and molding quality of the material, but also reduces the burden on the heating block.

[0034] After the traditional preheating of the material inside the material box, once the material is not completely used, it is easy to stick to the extrusion tube and the inner wall of the material box, which is difficult to clean and easy to be blocked during subsequent use. The preheating method of the material inside the material extrusion tube through the preheating frame can achieve local preheating, which is not easy to occur. Even if the material is not used up, the material is still in a dry state. When the printing is about to be completed, the preheating mechanism is evacuated, and the subsequent material continues to be transported. At this time, the cleaning work of the material extrusion tube can be completed to ensure that the device can be used normally in the future;

[0035] When preheating the material inside the material extrusion tube, the threaded shaft can be driven to rotate by starting the side frame, and the threaded shaft drives the outer threaded sleeve to move, and drives the sliding plate and the moving frame to move. At this time, the moving frame can drive the upper preheating frame close to the material extrusion tube, thereby realizing the work of preheating the material inside the material extrusion tube;

[0036] And when the material extrusion tube is preheated, by starting the second motor, the second motor can drive the rotating disk to rotate, and the rotating disk drives the upper heat insulator to rotate. At this time, the preheating frame and the heat insulator form a circular cylindrical structure, which can be surrounded by the outside of the material extrusion tube. At this time, the heat insulator can cooperate with the preheating frame to prevent heat from being dissipated and lost to the surroundings. This setting greatly reduces the waste of heat, so that its heat can be used to preheat the material extrusion tube in a targeted manner to ensure the preheating quality;

[0037] When the printing work is about to be completed, it can be moved away from the material extrusion tube in advance through the preheating frame to ensure that the material inside the material extrusion tube is solid and fully discharged. When the preheating frame is away from the material extrusion tube, the second motor drives the rotating disk to rotate, so that the heat insulator rotates to the inside of the preheating frame, which is convenient for the preheating frame to evacuate smoothly, and the heat insulator serves the purpose of heat insulation, preventing the preheating frame from continuing to preheat the material extrusion tube.

[0038] In actual use, the coolant for heat exchange passes through the circulation pump at high temperature for a long time, and the circulation pump is in a high-temperature working state for a long time, which may cause certain damage to the circulation pump. At this time, the first connecting pipe and the second connecting pipe are connected in parallel to the fourth water pipe and the outside of the first water pipe, and the second solenoid valve outside the fourth water pipe and the first solenoid valve outside the first water pipe are closed, and then the fourth solenoid valve outside the first connecting pipe and the third solenoid valve outside the second connecting pipe are opened. At this time, the circulation pump can be used to drive the flow of liquid inside the first connecting pipe and the second connecting pipe, and the heat exchange pipe is located inside the control module. The liquid is cooled when passing through the third hose. At this time, not only can the internal temperature of the circulation pump be reduced to ensure the normal use of the circulation pump, but the coolant can also reduce the temperature inside the control module through the heat exchange pipe to ensure the normal use of the components inside the control module.

[0039] When heat recovery is carried out, since heat is recovered through water, a water collecting tank is set at the bottom of the installation frame. Once water leakage occurs, the water will drip into the water collecting tank and gather in the groove. It can be monitored by a water leakage detector and an external alarm unit can be used to give a reminder, so that people can deal with it in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The output end of the circulation pump 507 is connected to a fourth water pipe 520, and the other end of the fourth water pipe 520 is connected to a moving frame 516, the top of the moving frame 516 is connected to a preheating frame 517 for preheating the material extrusion pipe 527, and the top of the preheating frame 517 is connected to a third water pipe 518, the other end of the third water pipe 518 is connected to a first hose 519, and the other end of the first hose 519 is connected to the second water pipe 510;

[0056] A second motor 524 is also fixedly connected inside the moving frame 516, and a rotating disk 525 is fixedly connected to the end of the main shaft of the second motor 524, and a vertically arranged heat insulator 526 is fixedly connected to the top of the rotating disk 525;

[0057] The inside of the side frame 511 is also fixedly connected to a first motor 512 arranged transversely, the main shaft end of the first motor 512 is fixedly connected to a threaded shaft 513, the other end of the threaded shaft 513 is rotatably connected to the side frame 511, the outer side of the threaded shaft 513 is spirally connected to two groups of threaded sleeves 514, and the outer side of the threaded sleeve 514 is fixedly connected to a sliding plate 515, the top of the sliding plate 515 is fixedly connected to the moving frame 516, and the bottom of the sliding plate 515 is slidably connected to the side frame 511;

[0058] A water leakage detection module 7 is also installed on one side of the bottom of the installation frame 506 .

[0059] The heat recovery pipes 509 are arranged in a spiral shape, and the heat recovery pipes 509 are all arranged between the heat dissipation plates of the radiator 505 .

[0060] A vertically arranged blocking plate 523 is fixedly connected to the upper inner portion of the side frame 511 , and the blocking plate 523 is located at one side of the moving frame 516 .

[0061] The preheating frame 517 and the heat insulator 526 are both arranged in a vertical semi-cylindrical shape, and the outer diameter of the heat insulator 526 is smaller than the inner diameter of the preheating frame 517 .

[0062] A first solenoid valve 521 is installed on the outer side of the first water pipe 508 , and a second solenoid valve 522 is installed on the outer side of the fourth water pipe 520 .

[0063] The steps of the recovery method of the above device are as follows:

[0064] Step 1: When the printer is started, the heating block 501 is used to heat the material to make it semi-liquid. At this time, the temperature of the heating block 501 is very high. When the heat of the heating block 501 of the printer is recovered, the spirally arranged heat recovery pipe 509 is used to cooperate with the radiator 505 to recover the heat through the flowing coolant, and the power of the liquid flow is provided by the circulation pump 507;

[0065] Step 2: When the cooling liquid spirally flows through the heat recovery pipe 509, it performs heat exchange. At this time, the heated liquid enters the preheating frame 517 through the fourth water pipe 520 and the moving frame 516. At this time, the preheating frame 517 can preheat the material inside the material extrusion pipe 527 inside it;

[0066] Step 3: During the preheating process of the material extrusion tube 527, the second motor 524 drives the rotating disk 525 to rotate, and the rotating disk 525 drives the heat insulator 526 to rotate, so that the heat insulator 526 is located on the opposite side of the preheating frame 517. At this time, the heat insulator 526 and the preheating frame 517 form a hollow cylinder to surround the material extrusion tube 527 for preheating;

[0067] Step 4: When the printing work is about to be completed, the heat insulator 526 rotates to the inside of the preheating frame 517, and the first motor 512 is started to drive the threaded shaft 513 to rotate, thereby driving the threaded sleeve 514 and the sliding plate 515 to move, and finally driving the moving frame 516 and the preheating frame 517 away from the material extrusion tube 527. At this time, the material extrusion tube 527 will not continue to be preheated;

[0068] Step 5: The heat dissipation module 6 is connected in parallel to the outside of the first water pipe 508 and the fourth water pipe 520 of the circulation pump 507. When the first solenoid valve 521 and the second solenoid valve 522 are closed, the third solenoid valve 610 and the fourth solenoid valve 611 are opened, and the circulation pump 507 drives the coolant to enter the heat exchange tube 605 through the first connecting pipe 601, and the heat exchange tube 605 is arranged inside the control module 4 to achieve heat dissipation inside the control module 4;

[0069] Step 6: In actual use, the water collection tank 701 is used to collect leaked water and is monitored by the water leakage detector 703. Once a leak occurs, an external alarm is used to warn, facilitating timely processing.

[0070] When the laser printer is in use, the material is heated by the heating block to make it semi-liquid, and then ejected through the nozzle. In the process of heating the material, the material cannot be overheated, otherwise the material will be liquid, which is not conducive to product molding. Once the heating is insufficient, the material will not be ejected smoothly, which is not conducive to product molding. The heating block generates a lot of heat when heating the material, and this excess heat is generally directly dissipated through the cooling fan, which will cause a lot of heat waste. The heating block 501, thermocouple 502, nozzle 503, thermal breaker 504 and radiator 505 of the device are all devices required for the printer to print, and are existing products. No more details will be given here. When in use, the radiator 505 The outer side is surrounded by a heat recovery pipe 509, and the cooling liquid is driven by the circulation pump 507 to circulate slowly inside the heat recovery pipe 509, and cooperates with the radiator 505 to achieve heat exchange, so that heat recovery can be achieved, and when this part of the heat flows through the preheating frame 517, and the preheating frame 517 is close to the material extrusion pipe 527, the material inside the material extrusion pipe 527 can be preheated, which not only ensures the heating and molding quality of the material, but also reduces the burden on the heating block 501. After the traditional preheating of the material inside the material box, once the material is not used completely, it is easy to stick to the extrusion pipe and the inner wall of the material box, which is not easy to clean and is easy to be blocked during subsequent use. The material preheating method inside the material extrusion tube 527 can achieve local preheating, and the above situation is not likely to occur. Even if the material is not used up, the material inside the material box is still in a dry state. It only needs to be evacuated when the printing is about to be completed. At this time, the subsequent material continues to be conveyed. At this time, the rear material squeezes the material in the preheating position. At this time, the cleaning work of the material extrusion tube 527 can be completed to ensure that the device can be used normally later. When the material inside the material extrusion tube 527 is preheated, the threaded shaft 513 can be driven to rotate by starting the side frame 511, and the threaded shaft 513 drives the outer threaded sleeve 514 to move, and drives the sliding plate 515 and the moving frame 516 to move. At this time, the moving frame 516 can drive the upper The preheating frame 517 is close to the material extrusion tube 527, so as to realize the work of preheating the material inside the material extrusion tube 527, and when the material extrusion tube 527 is preheated, by starting the second motor 524, the second motor 524 can drive the rotating disk 525 to rotate, and the rotating disk 525 drives the upper heat insulator 526 to rotate. At this time, the preheating frame 517 and the heat insulator 526 form a circular cylindrical structure, which can be surrounded by the outside of the material extrusion tube 527. At this time, the heat insulator 526 can cooperate with the preheating frame 517 to prevent heat from being dissipated and lost to the surroundings. This setting greatly reduces the waste of heat, so that its heat can be used to preheat the material extrusion tube 527 in a targeted manner to ensure the preheating quality. The heat insulator 526 is in this position for the purpose of heat preservation;When the printing work is about to be completed, it can move away from the material extrusion tube 527 in advance through the preheating frame 517 to ensure that the material inside the material extrusion tube 527 is solid and fully discharged. When the preheating frame 517 moves away from the material extrusion tube 527, it drives the rotating disk 525 to rotate through the second motor 524, so that the heat insulator 526 rotates to the inner side of the preheating frame 517, which facilitates the smooth withdrawal of the preheating frame 517. The heat insulator 526 serves the purpose of heat insulation, preventing the preheating frame 517 from continuing to preheat the material extrusion tube 527.

[0071] In this embodiment, when heat recovery is performed, the flow route of the cooling liquid is to start the circulation pump 507, and the liquid flows inside the heat recovery pipe 509 outside the radiator 505. At this time, the heat emitted by the radiator 505 is taken away by the liquid inside the heat recovery pipe 509, and enters the circulation pump 507 through the first water pipe 508, and then enters the movable frame 516 through the fourth water pipe 520. The fourth water pipe 520 can be bent to facilitate the subsequent movement of the movable frame 516. At the same time, the liquid inside the movable frame 516 enters the preheating frame 517. When the preheating frame 517 is attached to the material extrusion pipe 527, the liquid inside the movable frame 516 enters the preheating frame 517. When the material extrusion pipe 527 is close or close to the material extrusion pipe 527, the material transported inside is preheated to ensure the subsequent discharge of the material. At this time, the water temperature inside the preheating frame 517 drops, and the water after heat exchange enters the third water pipe 518 above, and then enters the first hose 519 through the third water pipe 518, and then enters the second water pipe 510, and finally re-enters the heat recovery pipe 509 for cyclic heat exchange and heat utilization. The first hose 519 is made of rubber at this time, which is convenient for it to bend when the preheating frame 517 is moved, so that the equipment can be used normally;

[0072] During the preheating operation, the material extrusion tube 527 located at the bottom of the preheating frame 517 is bent, and a notch is provided on one side below the preheating frame 517, so that the material extrusion tube 527 can be bent and inserted therein, and is arranged vertically upward, so that the material extrusion tube 527 can be located inside the preheating frame 517 when conveying materials, so that it is convenient to be preheated and the preheating quality is ensured. During the preheating operation, the heat insulator 526 and the preheating frame 517 can form a hollow cylinder, which helps to concentrate heat to preheat the material extrusion tube 527, and when the preheating frame 517 is evacuated from the outside of the material extrusion tube 527, the heat insulator 526 can be normally reset to the inside of the preheating frame 517, and the heat insulator 526 can be made of heat-insulating materials, such as asbestos.

[0073] When heat exchange is performed, the heat recovery pipe 509 is spirally arranged and partially embedded between the heat dissipation plates of the radiator 505, so that the heat exchange efficiency can be ensured;

[0074] When the moving frame 516 moves, the blocking plate 523 provided therein can effectively prevent the moving frame 516 from excessively moving toward the installation frame 506, thereby achieving the purpose of position limiting and blocking.

One end of the first connecting pipe 601 is connected to the fourth water pipe 520, and the other side of the first connecting pipe 601 is connected to the fourth hose 606, and the other end of the fourth hose 606 is connected to the heat exchange pipe 605, and the other end of the heat exchange pipe 605 is connected to the third hose 604, and the other end of the third hose 604 is connected to the heat exchanger 603, and the other end of the heat exchanger 603 is connected to the second hose 602, and the other end of the second hose 602 is connected to the second connecting pipe 607, and the other end of the second connecting pipe 607 is connected to the first water pipe 508;

[0079] During actual use, the coolant for heat exchange passes through the circulation pump 507 at high temperature for a long time, and the circulation pump 507 is in a high-temperature working state for a long time. At this time, the circulation pump 507 may be damaged to a certain extent. At this time, the first connecting pipe 601 and the second connecting pipe 607 are connected in parallel to the outside of the fourth water pipe 520 and the first water pipe 508. By closing the second solenoid valve 522 outside the fourth water pipe 520 and the first solenoid valve 521 outside the first water pipe 508, and then opening the fourth solenoid valve 611 outside the first connecting pipe 601 and the third solenoid valve 610 outside the second connecting pipe 607, the circulation pump 507 can be used to drive the liquid inside the first connecting pipe 601 and the second connecting pipe 607 to flow, and the heat exchange pipe 605 is located inside the control module 4. The liquid is cooled when passing through the inside of the third hose 604. At this time, not only can the internal temperature of the circulation pump 507 be reduced to ensure the normal use of the circulation pump 507, but the coolant can also reduce the temperature inside the control module 4 through the heat exchange pipe 605 to ensure the normal use of the internal components of the control module 4.

[0080] In this embodiment, when another set of heat dissipation system of the circulating pump 507 is started, the solenoid valve on the outside of the heat dissipation module 6 is opened, and the solenoid valve of the heat recovery module 5 is closed. At this time, the flow direction of the water body is: the first connecting pipe 601, the fourth hose 606, the heat exchange pipe 605, the third hose 604, the heat exchanger 603, the second hose 602 and the circulating pump 507. At this time, the water body is cooled when passing through the heat exchanger 603, and the cooled water body enters the circulating pump 507 to cool the circulating pump 507, ensuring that the circulating pump 507 can be used normally, and when entering the heat exchange pipe 605 again, the heat exchange pipe 605 is located inside the control module 4. At this time, the control module 4 can be subjected to heat exchange and cooling treatment, and the shape of the heat exchange pipe 605 can be appropriately adjusted inside the control module 4 according to actual conditions, and the setting of the guide ring 609 is used to ensure that the outside of the first connecting pipe 601 and the second connecting pipe 607 slide stably, and the setting of the fourth hose 606 and the third hose 603 can ensure that the mobile module 2 moves smoothly and normally.

[0082] This embodiment is an improvement made to Example 2. Figure 8 Specifically, the water leakage detection module 7 includes a water collecting box 701, a groove 702 and a water leakage detector 703.

A drain plug 704 is also installed on the outside of the water collecting box 701.

[0083] The front and rear inner walls of the water collecting box 701 are arranged in an inclined surface.

[0084] During heat recovery, since heat is recovered through water, a water collecting box 701 is provided at the bottom of the installation frame 506. Once water leakage occurs, the water will drip into the water collecting box 701 and collect in the groove 702. The water leakage detector 703 can monitor the leakage and the external warning unit can give a warning, so that people can handle the leakage in time.

[0085] In this embodiment, the front and rear inner walls of the water collecting box 701 are inclined surfaces. Once water leakage occurs, the water can smoothly enter the water collecting box 701 and gather into the groove 702 through the inclined surface. At this time, the water leakage detector 703 inside the groove can monitor and send a signal to the external warning unit (not shown in the figure) to facilitate people to understand and deal with it. The drain plug 704 is provided to facilitate the discharge of water. When the mobile module 2 drives the water collecting box 701 to the outside of the printer 1, the discharge work can be carried out to prevent water from dripping onto the printing platform.
