[0038] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0040] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0041] like Figures 1 to 4 As shown, some embodiments provide a dual-cylinder staining machine, including: a housing 1; the housing 1 is generally square, with a small overall footprint, which better meets the installation requirements of a laboratory; two staining cylinders 2 are arranged inside it; please also refer to... Figure 3 The dyeing tank 2 includes a dyeing chamber 21; the bottom surface of the dyeing chamber 21 is arc-shaped. Specifically, compared with related technologies, the bottom structure has been changed from a square structure to an arc-shaped structure, resulting in a larger capacity, less liquid at the bottom, and a lower bath ratio during use, thus achieving water conservation and emission reduction.
[0042] Please see Figure 1 and combined Figure 2 A door cover structure 3 is provided at the opening of the dyeing tank 2; the door cover structure 3 includes a cover body 31, which is set at the opening of the dyeing tank 2 via a hinge 4; a handle 32 is provided on the cover body 31, and part of the handle 32 is suspended outside the cover body 31; opening the cover is achieved by flipping the cover body 31 along the hinge 4, and the handle 32 has the effect of lifting the side of the cover body 31 at the symmetrical position of the hinge 4.
[0043] like Figure 2 and Figure 4As shown, to prevent the cover 31 from being opened under high pressure, a pressure relief valve 34 is also provided on the cover 31. The pressure relief valve 34 includes a handle 35. The handle 35 is located above the handle 32 to prevent the handle 32 from rotating the cover 31 along the hinge 4 to open it. That is, when the dyeing machine is in use, its interior is under high pressure. At this time, the handle 35 is in the state of tightening the pressure relief valve 34, that is, the handle 35 is suspended above the handle 32. If it is necessary to lift the handle 32, the handle 35 must be rotated outside the handle 32, that is, the handle 35 is rotated in the opposite direction of F. After the handle 35 is rotated in the opposite direction of F, the pressure relief valve 34 is in the state of venting, which releases the pressure inside the dyeing cylinder 2. Only then can the cover 31 be opened.
[0044] Please see Figure 1 and combined Figure 2 A pneumatic interlocking part 5 is provided on one side of the cover 31; the pneumatic interlocking part 5 includes a cylinder 51 and a push plate 52; the push plate 52 is installed at the output end of the cylinder 51; a controller 11 is provided on the top of the outer shell 1, and a temperature sensor 6 is provided on the inner wall of the cover 31; the controller 11 is electrically connected to the cylinder 51 and the temperature sensor 6, wherein when the temperature sensor 6 detects that the temperature of the dye liquor exceeds 85°C, the controller 11 controls the cylinder 51 to drive the push plate 52 to extend to the top of the cover 31, thus achieving a locking effect, and mechanical unlocking cannot open the cover 31, ensuring the safety of the dyeing machine during operation.
[0045] It should be further explained that, in order to meet diverse usage scenarios and environments, the dyeing tank 2 is equipped with a steam heating component and an electric heating component; the steam heating component and the electric heating component are electrically connected to the controller 11, wherein the dyeing liquor is heated by the steam heating component and / or the electric heating component.
[0046] like Figure 1 As shown, a pressure sensor 7 is provided on the inner wall edge of the cover 31; the pressure sensor 7 is electrically connected to the controller 11; when the pressure sensor 7 detects that the squeezing pressure between the cover 31 and the dyeing cylinder 2 is less than the set value, that is, when the pressure sensor 7 detects that the pressure is less than 5MPa, the controller 11 controls the steam heating component and / or the electric heating component to be turned off.
[0047] Please see Figure 4 The handle 35 is rotated in direction F to tighten the pressure relief valve 34. A stop pin 33 is fixed on the handle 32. The handle 35 abuts against the stop pin 33 to prevent the handle 35 from rotating excessively. In order to avoid excessive tightening, the pressure relief valve 34 is in a tightened state after rotating to a certain angle, that is, after the handle 35 abuts against the stop pin 33. This also avoids the phenomenon of excessive tightening causing wear on the connecting surface and resulting in air leakage.
[0048] Please refer to Figure 3The dyeing tank 2 includes a dyeing chamber 21; the bottom surface of the dyeing chamber 21 is arc-shaped. Specifically, compared with related technologies, the bottom has been changed from a square structure to an arc-shaped structure, resulting in a larger capacity, less liquid at the bottom, and a lower bath ratio during use, thus achieving the effect of water saving and emission reduction.
[0049] Please refer to Figure 1 and combined Figure 2 and Figure 4 Some embodiments also provide a dual-cylinder dyeing machine, including: a housing 1; inside which two dyeing cylinders 2 are disposed; please refer to Figure 3 The dyeing tank 2 includes a dyeing chamber 21; the bottom surface of the dyeing chamber 21 is arc-shaped. Specifically, compared with related technologies, the bottom has been changed from a square structure to an arc-shaped structure, resulting in a larger capacity, less liquid at the bottom, and a lower bath ratio during use, thus achieving the effect of water saving and emission reduction.
[0050] like Figure 2 As shown, the door cover structure 3 is located at the opening of the dyeing tank 2. The door cover structure 3 includes a cover body 31, which is located at the opening of the dyeing tank 2 via a hinge 4. A handle 32 is provided on the cover body 31, and part of the handle 32 is suspended outside the cover body 31. Opening the cover is achieved by flipping the cover body 31 along the hinge 4. The handle 32 has the effect of lifting the side of the cover body 31 at the symmetrical position of the hinge 4.
[0051] like Figure 1 and Figure 2 As shown, to further prevent the cover 31 from being accidentally opened, a pneumatic interlock 5 is provided on one side of the cover 31; the pneumatic interlock 5 includes a cylinder 51 and a push plate 52; the push plate 52 is installed at the output end of the cylinder 51; a controller 11 is provided on the top of the outer shell 1, and a temperature sensor 6 is provided on the inner wall of the cover 31. The controller 11 is electrically connected to the cylinder 51 and the temperature sensor 6; when the temperature sensor 6 detects that the dye liquor temperature exceeds 85°C, the controller 11 controls the cylinder 51 to drive the push plate 52 to extend to the top of the cover 31; this achieves a locking effect, and mechanical unlocking cannot open the cover 31, ensuring the safety of the dyeing machine during operation.
[0052] like Figure 2 and Figure 4As shown, to prevent the cover 31 from being opened under high pressure, and to further enhance the safety of the dyeing machine, a handle 32 is provided on the cover 31, with part of the handle 32 suspended outside the cover 31. A pressure relief valve 34 is also provided on the cover 31, including a handle 35. The handle 35 is positioned above the handle 32 to prevent the handle 32 from rotating the cover 31 open along the hinge 4. In other words, when the dyeing machine is in use, its interior is under high pressure, and the handle 35 is in the state of tightening the pressure relief valve 34, meaning the handle 35 is suspended above the handle 32. If it is necessary to lift the handle 32, the handle 35 must be rotated outside the handle 32, that is, rotated in the opposite direction of the pressure relief valve. After rotating the handle 35 in the opposite direction, the pressure relief valve 34 is in the venting state, releasing pressure inside the dyeing cylinder 2. Only then can the cover 31 be opened.
[0053] In summary, by setting a rotating handle 35 on the handle 32, this utility model requires that when opening the cover 31 through the handle 32, the handle 35 must be rotated to release pressure on the dyeing cylinder 2 through the pressure relief valve 34, thereby preventing the cover 31 from being opened under high pressure. This effectively prevents liquid or parts from splashing out during the use of the dyeing machine and causing injury to the operator, thus improving the safety of the dyeing machine.
