Description

Technical Field

[0001] The present application relates to the technical field of constant temperature control boxes, and specifically to a constant temperature control device for printing ink of a digital printing machine. Background Art

[0002] A digital printing machine is an advanced device that combines digital technology with traditional printing processes. It directly controls the inkjet system through a computer to accurately spray digital patterns onto the surface of fabrics or other materials, achieving efficient, flexible and personalized printing production. The printing ink of a digital printing machine is the core consumable in the digital printing process. It uses inkjet technology to accurately spray patterns onto the surface of fabrics or other materials. Its performance directly affects the printing effect, color fastness and applicable scenarios. Under normal circumstances, before printing, the temperature of the printing ink of the digital printing machine needs to be controlled between 25-30℃. The appropriate ink temperature can effectively control the changes in ink viscosity and the changes in the tension of the printed material surface, which can optimize the print quality.

[0003] The existing constant temperature control equipment for printing ink of digital printing machines usually consists of a box, a water cooling device installed in the box, and an ink collection box.

The temperature controller installed in the ink collection box can monitor the temperature of the ink in real time, thereby monitoring the temperature of the ink and cooling it to a constant temperature.

[0004] Although the above-mentioned device realizes the cooling and constant temperature regulation of ink, the ink after temperature regulation needs to be continuously cooled by water cooling equipment to keep it within the specified temperature range.

DETAILED DESCRIPTION

[0020] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor should belong to the protection scope of the present application.

[0022] As Figure 1-Figure 3As shown, the present application provides a constant temperature control device for printing ink of a digital printing machine, including a box 1, which is the outer shell of the constant temperature control device for printing ink of a digital printing machine. The cooling and constant temperature operation of the ink is carried out in the box 1. A base 2 is fixedly installed at the bottom of the box 1. The base 2 supports the box 1 and ensures the stable operation of subsequent ink cooling and constant temperature. A controller 3 is fixedly installed on one side of the top of the box 1. The controller 3 is the main control device of the constant temperature control equipment of the digital printing machine printing ink. The cooling and constant temperature operations of the ink are all achieved by sending instructions through the controller 3; A constant temperature water tank 13 is provided at the upper end of the housing 1. The constant temperature water tank 13 is mainly used to store ink, and the ink is also cooled and kept at a constant temperature in the constant temperature water tank 13. A water cooling device (not shown in the figure) is installed in the housing 1. The water cooling device includes a circulation pipe 14 placed in the constant temperature water tank 13. The circulation pipe 14 is filled with a coolant, and the coolant cools the circulation pipe 14. When the ink contacts the circulation pipe 14, the circulation pipe 14 is suitable for cooling the ink, thereby achieving cooling of the ink. The water cooling device has a temperature control function. The staff can control the coolant within a specified temperature range through the controller 3, thereby controlling the temperature of the circulation pipe 14, and further controlling the temperature of the ink after being cooled by the circulation pipe 14, so that the ink can be kept at a constant temperature after cooling; In this embodiment, a temperature detection system is installed in the constant temperature water tank 13. The temperature detection system is electrically connected to the controller 3. The staff can clearly know the real-time temperature of the ink through the controller 3, so that the water cooling device can be adjusted in time through the controller 3, thereby conveniently adjusting the temperature of the ink. A cover plate 4 is provided on the thermostatic water tank 13. First sliders 41 are fixedly mounted on both sides of the cover plate 4. A first chute is provided at the upper end of both sides of the thermostatic water tank 13. The first sliders 41 are slidably mounted in the first chute. Thus, the cover plate 4 is adapted to cover or open the upper end of the thermostatic water tank 13 by sliding. The sliding cover plate 4 facilitates real-time monitoring of the ink status after cooling and facilitates the removal of ink from the thermostatic water tank 13. However, in order to ensure the stability of the cover plate 4, a back plate 42 is fixedly installed on one side of the cover plate 4. Three groups of through holes 43 are opened on the back plate 42. The through holes 43 are arranged in parallel. At the same time, a limiting hole (not marked in the figure) is opened on the box body 1. The position and aperture size of the limiting hole are the same as those of the through holes 43. In addition, a back groove is opened on one side of the box body 1. The back groove is adapted to the back plate 42. The back plate 42 is suitable for being inserted into the back groove. At the same time, the limiting hole passes through the back groove. Continue to refer Figure 1-Figure 3In the initial state, the cover plate 4 closes the constant temperature water tank 13. For details, please refer to Figure 1 , and the rear plate 42 is inserted into the rear groove at this time, and the limit pin 44 is inserted into the through hole 43 and the limit hole. The limit pin 44 limits the rear plate 42 to prevent it from sliding, thereby ensuring the stable connection of the cover plate 4. When it is necessary to check the state of the ink in the constant temperature water tank 13, please refer to Figure 3 At this time, the cover plate 4 is in the open state, the rear plate 42 is separated from the rear groove, and the limit pin 44 is still inserted in the limit hole. At this time, the cover plate 4 can slide freely, which is convenient for checking the status of the constant temperature water tank 13 and can facilitate the quick removal or installation of the cover plate 4, which is convenient for regular inspection of the cover plate 4. At the same time, a handle is installed on the cover plate 4 to facilitate the staff to slide and pull the cover plate 4; In the present application, the rear plate 42 is limited by three limiting pins 44, which saves more time than the traditional bolt and screw hole connection, and does not require tools for installation or removal, making installation more convenient, thereby facilitating the use of the constant temperature control device for printing ink of the digital printing machine and improving its compatibility. like Figure 2-Figure 3 As shown, an auxiliary thermostatic assembly is installed above one side of the box body 1, and the auxiliary thermostatic assembly includes a first sub-pipe 6 installed above one side of the box body 1, one end of the first sub-pipe 6 is fixedly connected to and communicated with the circulation pipe 14, and a joint 61 is threadedly installed on the other end of the first sub-pipe 6, and a second sub-pipe 62 is threadedly installed on the other side of the joint 61, and the other end of the second sub-pipe 62 is in a blocked state. It should be noted that since the first sub-pipe 6 is communicated with the circulation pipe 14, the coolant in the circulation pipe 14 is suitable for entering the first sub-pipe 6 and flowing into the second sub-pipe 62. The first sub-pipe 6 and the second sub-pipe 62 are both affected by the coolant, and their temperatures will also drop. In the present application, the pipe walls of the first sub-pipe 6 and the second sub-pipe 62 are relatively thin, so that the first sub-pipe 6 and the second sub-pipe 62 can play a role in cooling. A discharge pipe 5 is provided on one side of the first auxiliary pipe 6, one end of which is fixedly connected to the box body 1 and leads to the constant temperature water tank 13. It is mainly used to transfer the ink in the constant temperature water tank 13, so that the ink in the constant temperature water tank 13 can be discharged from the discharge pipe 5 without using the cover plate 4. Since the constant temperature control device of the digital printing machine is used in different scenarios, the length of the discharge pipe 5 varies. In this application, the length of the discharge pipe 5 is relatively short, and the outer surface of the discharge pipe 5 away from the box body 1 is provided with a thread, so as to facilitate the connection between the discharge pipe 5 and the delivery pipe. The digital printing machine is connected to the end of the delivery pipe, that is, the ink delivered through the delivery pipe is directly input into the digital printing machine for use; Continue to refer Figure 2In this embodiment, the second auxiliary tube 62 is made of a flexible material and is provided with a connecting assembly, which is mainly used to connect the second auxiliary tube 62 to the delivery pipe. The connecting assembly includes at least two sets of Velcro 63 installed on the surface of the second auxiliary tube 62. The Velcro 63 is mainly used to adhere the second auxiliary tube 62 to the delivery pipe for delivering ink, so that the second auxiliary tube 62 can contact the delivery pipe for delivering ink. Since coolant flows in the second auxiliary tube 62, the cooled second auxiliary tube 62 is suitable for synchronously cooling the pipe in contact with it, so that the ink can still be cooled during the delivery process. It should be noted that a temperature detection device is provided at the end position of the discharge pipe 5, and a temperature detection device is also provided at the end of the conveying pipe, and a PLC control system is provided in the box body 1. The PLC control system is electrically connected to the temperature detection device and the water cooling device. The temperature detection device is mainly used to detect the temperature of the ink being conveyed. Through the auxiliary cooling of the second auxiliary pipe 62, the temperature of the ink can be made to recover more slowly during the conveying process. However, the temperature of the ink will still recover. For this reason, a temperature detection device is provided to detect the temperature of the ink being conveyed in real time. If the temperature of the ink rises during the output process, the temperature detection device will transmit the real-time temperature of the ink to the PLC control system. The PLC system receives the electrical signal and sends an instruction to the water cooling device to reduce the temperature of the coolant in the circulation pipe 14 to reduce the temperature of the ink in the constant temperature water tank 13, thereby controlling the temperature of the temporarily stored ink and the ink being conveyed in real time, thereby achieving the effect of constant temperature control of the ink. Furthermore, in the present application, the number of windings of the Velcro 63 and the second auxiliary pipe 62 can be adjusted according to usage requirements. If the second auxiliary pipe 62 is connected to the delivery pipe more tightly, the cooling effect of the delivery pipe will be better. Secondly, the connector 61 and the second auxiliary pipe 62 are threaded, which can support the rapid replacement of the second auxiliary pipe 62, thereby facilitating the rapid disassembly and connection of the second auxiliary pipe 62, further facilitating the maintenance or replacement of the second auxiliary pipe 62, thereby improving the compatibility of the constant temperature control device of the digital printing machine printing ink; Before performing digital printing operations, the staff is suitable for pouring ink into the constant temperature water tank 13, and then turning on the water cooling equipment through the controller 3. The coolant begins to circulate in the circulation pipe 14, which has a cooling effect on the circulation pipe 14. Since the ink is in direct contact with the circulation pipe 14, the circulation pipe 14 has a cooling effect on the ink, and the ink is cooled. After the cooling is completed, the ink needs to be transported to the digital printing machine. At this time, a delivery pipe needs to be installed at the discharge pipe 5. After the installation is completed, the staff sticks one end of the Velcro 63 on the second auxiliary pipe 62 to the delivery pipe, and wraps the second auxiliary pipe 62 around the delivery pipe. The second auxiliary pipe 62 has a cooling effect on the delivery pipe. The ink is then transported at a later time, which can effectively shorten the time required for the ink temperature to recover, thereby achieving a better cooling and constant temperature effect of the ink. The present application first cools the ink through the coolant in the circulation pipe 14, and then cools the ink for the second time by winding the second auxiliary pipe 62 around the delivery pipe, forming a double constant temperature guarantee, which can effectively keep the ink at the corresponding temperature after cooling, thereby facilitating the subsequent use of the ink. Moreover, since a temperature detection system is installed in the constant temperature water tank 13, the water cooling device can be linked with the temperature detection system, and the ink cooling operation can respond quickly in a short time, which facilitates the convenient use of the constant temperature control device of the digital printing machine printing ink. However, since the constant temperature water tank 13 is often in contact with liquid, it is inevitable that leakage will occur after a long period of use. If the leakage directly leaks into the box body 1, it is easy to damage the components inside the box body 1. In order to solve this problem, Figure 4-Figure 6 As shown, side panels 15 are fixedly installed on both sides of the box body 1, and a leak-proof component 7 is installed in the box body 1. The leak-proof component 7 includes a guide plate 71 arranged in the box body 1. The area of ​​the guide plate 71 is larger than the area of ​​the constant temperature water tank 13 and is located directly below the constant temperature water tank 13. If the constant temperature water tank 13 leaks, the liquid is suitable for flowing directly onto the guide plate 71. A third slider 76 is fixedly installed on one side of the guide plate 71. At the same time, a third chute is opened on one side of the side panel 15, and the third slider 76 is slidably installed in the third chute; It should be noted that an opening is provided at one end of the third chute, so that the third slider 76 is suitable for sliding out of the third chute through the opening, so as to facilitate taking the deflector 71 out of the box body 1. Secondly, the third chute is inclined, and it is inclined downward in a direction away from the opening. At the same time, the third slider 76 is also inclined. When the deflector 71 is located in the box body 1, due to the cooperation of the third slider 76 and the third chute, the deflector 71 will not easily slide out of the opening. If it is subjected to vibration or other external forces, due to its inclined setting, it will automatically reset after contact with the external force. In the application, the deflector 71 is arranged obliquely, which can more conveniently collect and process the leaked liquid. In addition, the deflector 71 is arranged obliquely towards one end, and under the condition of no external force, it is arranged obliquely towards the side with lower height, and it is automatically reset after the external force is removed, thereby improving the stability of the deflector 71. The horizontal plate 72 is fixedly installed on both sides of the deflector 71, which can prevent the liquid from flowing out from both sides of the deflector 71. By arranging the horizontal plate 72, the leaked liquid can be better prevented from flowing out of the deflector 71, so that it can be stored on the deflector 71, thereby further improving the safety of the constant temperature control device for printing ink of the digital printing machine. The collecting plate 73 is arranged on the side of the deflector 71 away from the third sliding groove. The second sliding block 75 is fixedly installed on both sides of the collecting plate 73. The second sliding groove is arranged on the side of the deflector 71 away from the third sliding groove, and the fourth sliding groove is arranged on the side plate 15 on the other side. The second sliding block 75 is slidably connected with the second sliding groove and the fourth sliding groove, thereby facilitating the taking out of the collecting plate 73 from the box body 1. It should be noted that the top surface of the deflector 71 is arranged obliquely, and it is arranged obliquely downwards towards the direction close to the collecting plate 73, so that the liquid on the deflector 71 flows to the collecting plate 73 due to the action of gravity and is temporarily stored in the collecting plate 73, thereby achieving the effect of collecting the leaked liquid. In order to facilitate the taking out of the collecting plate 73 from the box body 1, as shown in Figure 2-Figure 5 - Figure 6 The side cover 11 is arranged on one side of the box body 1. The side cover 11 is fixedly connected with the box body 1 through bolts at four corners. The plug 12 is arranged on the side cover 11 and is connected with the side cover 11 in a plug-in manner. The cross-sectional shape of the plug 12 is the same as that of the collecting plate 73. When the plug 12 is plugged into the side cover 11, the side cover 11 is in a closed state. After the plug 12 is taken out, the side cover 11 is in an open state. At this time, the liquid on the collecting plate 73 can be taken out from the side cover 11. In order to facilitate the pulling out of the collecting plate 73 from the side cover 11, the second handle 74 is fixedly installed on the side of the collecting plate 73 close to the side cover 11. The staff is adapted to pull the second handle 74, so as to play a pulling role on the collecting plate 73 in the subsequent process. If the collecting plate 73 is taken out from the box body 1, the staff needs to disassemble the bolts at four corners of the side cover 11 first, and then holds the second handle 74 to pull out the collecting plate 73. Through the cooperation of the second sliding block 75, the second sliding groove, the fourth sliding groove and the side cover 11, the collecting plate 73 can be conveniently taken out from the box body 1, thereby facilitating the treatment of the liquid and the cleaning of the collecting plate 73. In the present application, the side cover 11 is a straight-through design. After removing the side cover 11, the staff can directly pull the collecting plate 73 out of the box body 1 through the second handle 74. The operation is simple and convenient, which facilitates the staff to collect the leaked liquid in the box body 1 and improves the compatibility of the constant temperature control equipment of the digital printing machine printing ink; like Figure 7-Figure 8 If locking sill 752 is positioned between locking sill 74 and locking sill 71, then lock sill 71 is located in the position that stretches out the upside of locking sill 71, and lock sill 71 is in the position of being fixed on the top of lock sill 71. In the present application, the guide plate 71 is a pull-out design used in conjunction with a chute, which can realize the rapid installation and removal of the guide plate 71, thereby facilitating the inspection and maintenance of the guide plate 71. In the event of leakage, the leaked liquid on the guide plate 71 can be quickly cleaned to prevent the liquid from being left on the guide plate 71 without being processed and damaging the guide plate 71. Secondly, the block 12 blocks the collecting plate 73 from the side, thereby facilitating the uniformity of sealing and removing the collecting plate 73, and making the operation more convenient. The leak-proof assembly 7 of the present application reduces the risk of liquid leakage invading the core area of ​​the equipment through the stepped drainage design of the guide plate 71 and the collecting plate 73, combined with the directional quick-release structure of the side cover 11. At the same time, the flexible winding cooling solution of the second auxiliary pipe 62 breaks through the temperature control blind spot during the transportation process, so that the ink is kept in a dynamic constant temperature environment from storage to printing, thereby improving the reliability of the equipment and facilitating the maintenance of the constant temperature control equipment of the digital printing machine. It should be noted that the cover plate 4, the guide plate 71 and the second auxiliary pipe 62 in the present application can be disassembled by hand, which reduces the labor intensity of the staff in subsequent inspection and maintenance. The cover plate 4, the guide plate 71 and the second auxiliary pipe 62 are easy to disassemble and install, and further improve the compatibility of the constant temperature control device of the digital printing machine printing ink; Secondly, in the present application, the guide plate 71 is used for inclined drainage, and the horizontal plate 72 is used to prevent the leakage from overflowing on the side. In addition, the limit pin 44 plays a role in limiting and resisting the guide plate 71 to prevent shock. The triple protection prevents the leakage from reaching the box 1 and damaging the electrical components in the box 1, thereby improving the safety of the constant temperature control device of the digital printing machine printing ink; When the digital printing machine needs to use the constant temperature control device for printing ink, the staff first needs to remove the cover plate 4, then pour the ink that needs to be cooled into the constant temperature water tank 13, and then start the water cooling device to cool the ink through the circulation pipe 14. During this process, the staff can easily cover or remove the cover plate 4 to observe the cooling status of the ink; After the ink has finished cooling, when the ink needs to be used, the staff will connect the delivery pipe to the discharge pipe 5, and then manually fit the second auxiliary pipe 62 to the delivery pipe, and then stick one end of the Velcro 63 on the second auxiliary pipe 62 to the delivery pipe. The delivery pipe is cooled by the second auxiliary pipe 62. When the ink is transported through the delivery pipe, the delivery pipe cools the ink at a constant temperature, prolonging the time for the ink temperature to recover, thereby achieving a better ink cooling effect. In addition, the temperature detection device at the joint 51 and the temperature detection device at the end of the delivery pipe can be used to detect the temperature of the ink in the delivery process in real time. The temperature detection device is electrically connected to the PLC control system, and the temperature of the ink can be transmitted to the PLC control system in real time, so that the PLC control system can adjust the temperature of the coolant in the water cooling device according to the temperature to achieve the effect of constant temperature control of the ink. When leakage occurs, the liquid leaked from the thermostatic water tank 13 will flow onto the guide plate 71. Since the guide plate 71 is arranged at an angle, the liquid will flow onto the collecting plate 73 due to gravity and be temporarily stored in the collecting plate 73. If the liquid in the collecting plate 73 needs to be cleaned, the staff only needs to remove the cover plate 4 and then manually pull the second handle 74 to pull out the collecting plate 73 and then pour out the liquid. In addition, the staff can also disassemble the side of the box body 1 and manually pull out the guide plate 71 to clean the liquid remaining on the guide plate 71, which is convenient for the subsequent maintenance and inspection of the thermostatic control equipment of the digital printing machine printing ink. To sum up, the present application is provided with a first auxiliary pipe 6 and a second auxiliary pipe 62, which can be connected to the delivery pipeline, thereby facilitating the cooling of the ink during the delivery process and further improving the quality of ink cooling. Secondly, a leak-proof component 7 is also provided, which can carry out targeted treatment for possible leakage in the constant temperature water tank 13 to prevent the leaked liquid from damaging the electrical components in the box body 1, thereby improving the service life of the constant temperature control box.

[0023] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
