Example

[0035] A constant temperature storage device for water-based UV varnish production, comprising a housing 1, a protective cover 2, a heating tube 3, a mounting plate 31, a buffer mechanism 4 and a heat conducting mechanism 5, see Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, a mounting plate 31 is fixedly connected to the lower inner part of the shell 1 along the circumferential direction, a heating tube 3 is fixedly connected to the middle of the mounting plate 31, a protective cover 2 is rotatably connected to the top of the shell 1, a buffer mechanism 4 is provided on the top of the mounting plate 31, the buffer mechanism 4 is used to place a container filled with water-based UV varnish, and a heat conducting mechanism 5 is provided on the shell 1, the heat conducting mechanism 5 is used to conduct heat to the container.

[0036] Also includes a handle 21, see Figure 1 As shown, handles 21 are fixedly connected to the middle of the left and right sides of the protective cover 2.

[0037] The buffer mechanism 4 includes a buffer plate 41, a sleeve 42, a first spring 43 and a temperature sensor 44, see Figure 2 、 Figure 5 and Figure 6 As shown, four sleeves 42 are fixedly connected to the top of the mounting plate 31 at uniform intervals along the circumferential direction, and a buffer plate 41 is slidably connected between the four sleeves 42. The buffer plate 41 is used to place the container. A first spring 43 is connected between the bottom of the buffer plate 41 and the bottom of the four sleeves 42. A temperature sensor 44 is fixedly connected to the middle of the top of the buffer plate 41, and the temperature sensor 44 is circuit-connected to the heating tube 3.

[0038] The heat conduction mechanism 5 includes a heat conduction plate 51, a heat conduction arc plate 52, a telescopic rod 53, a contact rod 54, a second spring 55, a mounting bracket 56 and a swing plate 57. Figure 1 、 Figure 2 and Figure 7As shown, the middle of the front and rear sides of the shell 1 are connected with telescopic rods 53, and a heat-conducting arc plate 52 is fixed between the inner ends of the two telescopic rods 53 on the front side, and a heat-conducting arc plate 52 is also fixed between the inner ends of the two telescopic rods 53 on the rear side. The material of the heat-conducting arc plate 52 is metal. When the heat-conducting arc plate 52 contacts the container, the heat-conducting arc plate 52 can conduct heat to the container. Two mounting brackets 56 are fixed on the front and rear sides of the top of the mounting plate 31. The inner ends of the four mounting brackets 56 are rotatably connected with a swing plate 57. When the swing plate 57 swings, the swing plate 57 can drive the heat to be conducted. The hot arc plate 52 moves inward, and the lower parts of the four mounting brackets 56 are slidably connected to the contact rod 54. When the contact rod 54 moves outward and contacts the swing plate 57, the contact rod 54 can drive the swing plate 57 to swing, and the buffer plate 41 moves downward and contacts the contact rod 54. The outer side surfaces of the four contact rods 54 are respectively connected to the inner side surfaces of the four mounting brackets 56. A second spring 55 is connected between the outer side surfaces of the four contact rods 54 and the inner side surfaces of the four mounting brackets 56. A heat conducting plate 51 is fixed to the middle of the front and rear sides of the shell 1. The heat conducting plate 51 is located between the left and right mounting brackets 56. The heat conducting plate 51 is slidably mounted on the telescopic rod 53.

[0039] First, hold the handle 21 and twist the protective cover 2 in reverse to move it upward through the thread. Due to the action of the handle 21, it is more convenient to twist the protective cover 2. The protective cover 2 moves upward and disengages from the shell 1. Then put the container filled with water-based UV light into the shell 1. The container is placed on the buffer plate 41. Due to the weight of the container, the container drives the buffer plate 41 to move downward. The first spring 43 is compressed, and the buffer plate 41 moves downward to drive the four contact rods 54 to move outward. The second spring 55 is compressed, and the four contact rods 54 move outward to drive the lower parts of the four swing plates 57 to swing outward. The lower parts of the four swing plates 57 swing outward to make the upper parts swing inward. The upper parts of the four swing plates 57 swing inward to drive the front and rear heat-conducting arc plates 52 to move inward. The telescopic rod 53 is stretched, and the front and rear heat-conducting arc plates 52 move inward to contact the container. Then put the protective cover 2 back to its original position, twist the protective cover 2 to rotate forward and move it downward through the thread to reset. The protective cover 2 will be inside the shell 1 Close and start the heating tube 3. The heating tube 3 begins to heat the shell 1. At the same time, the heat is also introduced into the front and rear heat conducting plates 51. The heat in the front and rear heat conducting plates 51 is introduced into the front and rear telescopic rods 53. The heat in the front and rear telescopic rods 53 is introduced into the front and rear heat conducting arc plates 52. The heat in the front and rear heat conducting arc plates 52 is introduced into the container, thereby heating the water-based UV varnish to a constant temperature state. Since the heat conducting arc plates 52 are made of metal, metal conducts heat faster than air, which enables the water-based UV varnish to reach a constant temperature state faster, and the working efficiency is high. At the same time, the heat in the shell 1 also heats the container. When the temperature sensor 44 detects that the temperature reaches the constant temperature state, the temperature sensor 44 controls the heating tube 3 to turn off, and the heating tube 3 stops emitting heat. When the temperature in the container drops and does not reach the constant temperature state, the temperature sensor 44 detects and controls the heating tube 3 to start again, thereby making the temperature reach the constant temperature state again. When the container needs to be taken out, the protective cover 2 is removed according to the above operation, and then the container is taken out of the shell 1. The container is out of contact with the buffer plate 41. Due to the action of the first spring 43, the buffer plate 41 is reset without limiting the contact rod 54. Due to the action of the second spring 55, the contact rod 54 moves inward and resets without limiting the swing plate 57. Due to the action of the telescopic rod 53, the front and rear heat-conducting arc plates 52 move outward and reset, driving the swing plate 57 to swing and reset. Example

[0040] On the basis of embodiment 1, a flow guiding mechanism 6 is further included. The flow guiding mechanism 6 includes a partition 61, a driving motor 62, a fan blade 63, a dustproof net 64 and an air guide pipe 65. Figure 2 and Figure 8As shown, a partition 61 is fixedly connected to the lower part of the shell 1 along the circumferential direction, and the partition 61 is located below the mounting plate 31. A dustproof net 64 is fixedly connected to the middle of the partition 61, and a fan blade 63 is rotatably connected to the middle of the dustproof net 64. When the fan blade 63 rotates, the fan blade 63 can blow the hot air to flow. A drive motor 62 is fixedly connected to the middle of the bottom of the shell 1, and the output shaft end of the drive motor 62 is fixedly connected to the bottom end of the fan blade 63. An air duct 65 is connected to the left side of the shell 1, and the lower right end of the air duct 65 is located below the partition 61.

[0041] The protective mechanism 7 includes a connecting rod 71, a mounting plate 72, a hollow rod 73, a third spring 74 and a rotating plate 75. Figure 2 and Figure 9 As shown, a connecting rod 71 is fixedly connected to the middle of the top of the protective cover 2, and a hollow rod 73 is slidably mounted on the connecting rod 71. A third spring 74 is connected between the bottom of the hollow rod 73 and the bottom end of the connecting rod 71. A mounting plate 72 is fixedly connected to the bottom end of the hollow rod 73, and a turntable 75 is rotatably connected to the bottom of the mounting plate 72. When the turntable 75 contacts the container, the turntable 75 can protect the container.

[0042] When the water-based UV varnish is being stored at a constant temperature, the drive motor 62 is activated, and its rotation drives the fan blades 63. This rotation blows the hot air within the housing 1 into the air duct 65, which then flows into the lower portion of the housing 1. The fan then vents the hot air from the lower portion of the housing 1 back into the upper portion of the housing 1, thus continuously circulating the hot air and maintaining a constant temperature for the water-based UV varnish. When the container is removed from the housing 1, the drive motor 62 is turned off, and the fan stops. This ensures that the hot air within the housing 1 is evenly distributed, ensuring the constant temperature storage of the water-based UV varnish.

[0043] When the protective cover 2 reverses and moves upward, the protective cover 2 reverses and drives the connecting rod 71 to reverse. The reverse connection rod 71 reverses and drives the hollow rod 73 to reverse through the third spring 74. The reverse connection rod 73 drives the mounting plate 72 to reverse. The mounting plate 72 reverses and slides on the rotating disk 75. When the protective cover 2 is removed, the mounting plate 72 and the rotating disk 75 also move outside the housing 1. When the protective cover 2 is returned to its original position, the rotating disk 75 moves into the housing 1 and contacts the container. The container limits the rotating disk 75, and the rotating disk 75 limits the mounting plate 72. The mounting plate 72 limits the hollow rod 73. As the protective cover 2 moves downward to reset, the protective cover 2 moves downward and drives the connecting rod 71 downward. The third spring 74 is compressed, and the rotating disk 75 limits the container. In this way, the container is further limited, ensuring that the container will not easily move and affect storage. Example

[0044] On the basis of embodiment 1 and embodiment 2, an auxiliary mechanism 8 is further included. The auxiliary mechanism 8 includes a mounting shaft 81 and an auxiliary wheel 82. Figure 2 、 Figure 3 、 Figure 10 and Figure 11 As shown, at least ten mounting shafts 81 are fixedly connected to the turntable 75 at even intervals along the circumference, and an auxiliary wheel 82 is rotatably mounted on the mounting shaft 81. The auxiliary wheel 82 contacts the inner side of the mounting disk 72 and is used to guide the mounting disk 72.

[0045] Also includes a heat preservation mechanism 9, the heat preservation mechanism 9 includes a mounting block and heat preservation cotton 92, see Figure 1 、 Figure 2 、 Figure 13 and Figure 14 As shown, mounting blocks 91 are fixed symmetrically on the upper and lower sides of the outer left side of the shell 1 , and thermal insulation cotton 92 is fixed between the two mounting blocks 91 , and the thermal insulation cotton 92 is sleeved on the air guide pipe 65 .

[0046] When the mounting plate 72 rotates, the mounting plate 72 drives the auxiliary wheel 82 to rotate, and the auxiliary wheel 82 guides the mounting plate 72, so that the mounting plate 72 can rotate more smoothly.

[0047] When the hot air circulates in the air duct 65, the heat-insulating cotton 92 can keep the air duct 65 warm, preventing the air duct 65 from being affected by external factors and ensuring that the temperature of the hot air does not drop.

[0048] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in this field based on the above content of the present invention are all within the scope of protection required by the present invention.
