FIG. 5 is a schematic structural view of a circulating ink path dual heating module according to the present invention; the device comprises a module shell, two ink constant temperature control devices are fixedly arranged in the module shell, and part of the structure of the insulating layer is not shown in the figure.
FIG. 6 is an exploded view of a dual heating module of the circulating ink path of the present invention; as can be seen from the figure, the number of the ink constant temperature control devices in the circulating ink path double-heating module is two, and the two ink constant temperature control devices are arranged oppositely.
As shown in fig. 1 to 4, the present invention provides an ink thermostatic control device which is reversely improved based on a water cooling device and has a small size and a low cost. High heat conversion efficiency. The ink constant temperature control device mainly comprises a heat exchanger 1 and a temperature adjusting device 2, wherein the heat exchanger 1 is integrally of a hollow plate-shaped structure, a reciprocating flow channel 11 separated by a partition plate 5 is arranged in the heat exchanger, and an ink inlet 3 and an ink outlet 4 are respectively arranged at two ends of the flow channel 11; the temperature adjusting device 2 is fixedly arranged on the upper surface or the lower surface of the heat exchanger 1, and the temperature adjusting device 2 is of a sheet structure.
Because the heat exchanger 1 in the water cooling device is selected as the temperature control carrier, the problems of large size, high cost and low heat conduction efficiency of the traditional temperature control equipment are ingeniously solved.
The overall dimensions of the heat exchanger 1 may be 100mm x 40mm x 20 mm.
The traditional water cooling equipment realizes mold opening mass production, has extremely low production cost, and can flexibly change the size and the interface, thereby greatly reducing the production and processing cost of the temperature control equipment.
It is noted that by comparing the outer contour lines projected in the vertical direction, it can be known that the outer contour line of the temperature adjusting device 2 coincides with the cavity outer contour line of the heat exchanger 1, or that the outer contour line of the temperature adjusting device 2 is located outside the cavity outer contour line of the heat exchanger 1.
Under the effect of temperature adjusting device 2, the temperature of heat exchanger 1 itself can change and infinitely laminate with the temperature that temperature adjusting device 2 set for, consequently can guarantee through these that temperature adjusting device 2 can be to heat exchanger 1 everywhere even heating to guarantee that heat exchanger 1 is unanimous at the different position temperature on the horizontal plane. At the same time, this heating method has less heat loss.
Because the temperature adjusting device 2 is directly contacted with the heat exchanger 1, and the ink flows in the heat exchanger 1 through the reciprocating flow channel 11, the contact area between the ink and the heat exchanger 1 is increased, meanwhile, the time for the ink to flow in the heat exchanger 1 is prolonged, the ink can be fully heated or cooled to a preset temperature, and the temperature of the ink flowing out of the device is ensured to be consistent. Meanwhile, the device makes full use of the heat or cold generated by the temperature adjusting device 2 during working, so that the working efficiency of the device is higher, and the energy loss is smaller.
In addition, it should be noted that, in the conventional ink heating system, in order to prevent the ink from being excessively heated during an abnormal shutdown, the forced ink path circulation system needs to be activated. This design greatly increases the complexity of the system and reduces the reliability of the system. The ink constant temperature control device in the scheme has high heat conduction efficiency and good heat insulation performance, so that the set temperature of the ink can be more conveniently reached, and the control temperature difference between the set temperature of the ink and the temperature regulating equipment is smaller than that of a common traditional heating system. Therefore, the temperature rise of the ink is not excessively high even when the system is abnormally stopped. Therefore, a forced ink path circulating system is not required to be added, the system design is simplified, and the reliability of the device is improved.
For practical production needs, the temperature adjusting device 2 may be a heating plate or a cooling plate as an alternative embodiment. When the device is a refrigerating piece, a semiconductor refrigerating piece can be selected; when the device is a heating sheet, a polyimide heating film can be selected. Compared with the traditional heating equipment, the polyimide heating film has the characteristics of high heating speed, safety in use and higher flexibility in use. The polyamide heating film can be directly powered by a direct current safe voltage when in use, is rapid to heat, is thin in thickness, and can be customized into various shapes.
Specifically, the power of the direct-current 24V polyamide heating film is 70-100W, and the thickness of the direct-current 24V polyamide heating film is 0.15-0.25 mm.
The power of the traditional ceramic heating plate is low and is 3-10W.
As an alternative embodiment, the baffles 5 located inside the heat exchanger 1 are all horizontally arranged and all the baffles 5 are divided into two types: a guide plate 51 not connected to the side wall of the partition 5 and a deflector plate 52 connected to one side wall. When the ink flows to both ends of the turning plate 52, the flow direction needs to be changed to continue flowing along the flow channel 11.
The deflector 51 can move the ink from one side to the other side of the interior of the heat exchanger 1 and the deflector 52 can redirect the flow of ink within the heat exchanger 1, thus achieving a reciprocating flow. The ink prolongs the stay time in the heat exchanger 1 in the reciprocating flowing process, and can ensure that the ink can reach the preset temperature.
In order to detect the temperature of the ink, a temperature measuring device 8 needs to be attached to the heat exchanger 1.
In order to ensure that the ink does not leak and the installation is convenient, the temperature measuring device 8 is not suitable for being installed in the heat exchanger 1, so that the temperature measuring device needs to be installed outside the heat exchanger 1 to detect the temperature of the ink by measuring the surface temperature of the heat exchanger 1. It should be considered that the closer the surface of the heat exchanger 1 is to the heating plate (cooling plate), the higher the temperature is (the lower the temperature is), and the temperature difference exists between the final heating temperature (cooling temperature) of the ink and the surface temperature of the heat exchanger 1, so it is reasonable to choose the temperature measuring device 8 on the surface of the heat exchanger 1 far from the heating plate (cooling plate). In addition, it is preferable that the temperature measuring device 8 is installed on the side surface of the heat exchanger 1 in view of convenience of installation and good appearance. Of course, the side of the heat exchanger 1 facing away from the heating fins (cooling fins) is also possible.
Specifically, the temperature measuring device 8 is a sheet-shaped temperature measuring sensor.
When the ink temperature control device is used, the temperature control device 2 can adjust the working condition through the temperature data measured by the temperature measuring device 8 so as to ensure the stability of the ink temperature.
For safety, a thermal protector needs to be connected in series on a temperature control circuit of the device, so that the situation that the temperature is too high or too low when a temperature sensor fails is prevented.
As an alternative embodiment, the partition 5 is provided in the longitudinal direction or the width direction of the heat exchanger 1.
Specifically, the turning plates 52 are respectively connected with the opposite side plates at two sides and the turning plates 52 connected with different side plates are arranged at intervals, and the guide plates 51 are distributed among the turning plates 52, and the specific structure of the guide plate is shown in fig. 2-3.
It should be noted that the ink inlet 3 and the ink outlet 4 may be located on the same side of the heat exchanger 1, or may be located on two opposite sides, or may be located on two adjacent sides according to actual requirements. The distribution order of the diversion plate 52 and the diversion plate 51 may be different as the relative positions of the ink inlet 3 and the ink outlet 4 are changed.
In the above technical solution, it is preferable that the heat exchanger further includes a heat insulating layer 7, and the heat insulating layer 7 is located outside the heat exchanger 1 and wraps the heat exchanger 1 and the temperature adjusting device 2. The heating efficiency of the device can be improved by wrapping the device with the heat insulation layer 7.
The heat insulation layer 7 is made of high temperature resistant fiber paper. The high-temperature resistant fiber paper is used as a novel heat insulation material and has the characteristics of high temperature resistance, good heat insulation effect, thin material, convenient processing and the like. The heat insulation layer 7 made of high-temperature-resistant fiber paper has the advantage of small size, and can help to reduce the power of the temperature adjusting device 2 and improve the temperature adjusting effect.
As an alternative embodiment, the heat exchanger 1 is machined from metallic aluminum.
The surface of the aluminum material is provided with a layer of compact oxide film. The oxide film has stable property, does not generate chemical reaction with ink, and can effectively solve the problem of material compatibility. Meanwhile, the thermal conductivity of the aluminum material is superior to that of a stainless steel material, and the aluminum material can improve the heat exchange efficiency of the device and effectively reduce the weight of equipment.
In order to avoid ink leakage in consideration of ink flowing into the device through an ink path, quick-screwing right-angle connectors 6 are arranged at the ink inlet 3 and the ink outlet 4.
The ink tube pipe diameter in the printer is less relatively, and the ink tube inflation is great after the heating, uses traditional pagoda head to appear pine easily, leaks the condition of china ink, consequently chooses for use soon to twist the locking ink tube that right-angle joint 6 can be firm, guarantees that the junction of ink tube and ink inlet 3 or ink outlet 4 can not pine and take off hourglass china ink.
Specifically, the quick-twist right-angle connector 6 is a 316 stainless steel quick-twist right-angle connector 6.
It should be noted that the ink thermostatic control device can be located between the ink box and the nozzle, directly connecting the ink box and the printer nozzle, or can be installed on other ink paths of the printer, such as a circulating ink path.
As shown in fig. 5-6, the present invention further provides a dual heating module for a circulating ink path, which comprises two ink thermostatic control devices connected via an ink tube, and is applied to the circulating ink path.
When the ink jet head is used, part of the jet head works in a circulating ink supply mode, and part of ink which is not jetted needs to flow back to the ink box. In order to avoid the ink temperature in the ink box of backward flow influence, set up two heating module, one of them heating module is located the shower nozzle outlet side, and another is located the backward flow ink pipeline and reheats the ink again to guarantee the temperature of backward flow ink, also can reduce the power of the heating module of shower nozzle department, improve heating efficiency, make the heating faster.
