DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-8 This application is described in further detail.

[0026] The present application embodiment discloses an adjustable pressure wheel mechanism of a plotter, comprising a plurality of pressure wheel assemblies 2, the pressure wheel assemblies 2 are linearly arranged and installed on a plotter frame, the pressure wheel assemblies 2 each comprise a housing 21 and a wheel plate member rotatably installed in the housing 21, the pressure end of the wheel plate member is located outside the housing 21, a tension spring 25 is provided at the control end of the wheel plate member, a pressure regulating mechanism 3 is provided at the upper end of the tension spring 25, and the pressure regulating mechanism 3 regulates the pressure of the pressure wheel body 26 by regulating the pressure of the tension spring 25;

[0027] It also includes an independent control mechanism 4 and a linkage control mechanism 5. The independent control mechanism 4 is arranged at the end of the wheel plate control end, and can lift or press down one group of wheel plates independently; the linkage control mechanism 5 is arranged at the head end of the wheel plate control end, and can lift or press down all wheel plates at the same time.

[0028] In this embodiment, by setting up an independent control mechanism 4, any group of wheel plates can be lifted or pressed down individually; by setting up a linkage control mechanism 5, all wheel plates can be lifted or pressed down at the same time, and it can be flexibly adjusted according to actual usage to improve the utilization rate of the pressure wheel assembly 2.

[0029] Furthermore, the wheel plate components include a pressure wheel plate 23, which is rotatably connected to the shell 21 through a wheel plate shaft 24, and one end of the pressure wheel plate 23 is located outside the shell 21 and is rotatably connected to the pressure wheel body 26 through the pressure wheel shaft 22, and the other end of the pressure wheel plate 23 is fixedly connected to the lower end of the tension spring 25.

[0030] Furthermore, the independent control mechanisms 4 include a pressure wheel trigger 41, a trigger shaft 42 and a trigger torsion spring 43. The pressure wheel trigger 41 is arranged as an inverted "Y"-shaped structure. The upper part of the pressure wheel trigger 41 is rotatably connected to the housing 21 through the trigger shaft 42. A trigger torsion spring 43 is sleeved on the surface of the trigger shaft 42. One end of the trigger torsion spring 43 abuts against the housing 21, and the other end of the trigger torsion spring 43 abuts against the pressure wheel trigger 41. One end of the lower part of the pressure wheel trigger 41 is slidably matched with the pressure wheel plate 23, and the other end of the lower part of the pressure wheel trigger 41 is an interactive end.

[0031] In this embodiment, the end of the pressure wheel plate 23 is set to be trapezoidal, which can ensure that the end of the pressure wheel plate 23 and the pressure wheel trigger 41 move in coordination with each other.

[0032] In this embodiment, when it is necessary to lift or press down a certain group of pressure roller bodies 26 separately, it is only necessary to adjust the independent control mechanism 4 corresponding to the wheel plate. Specifically, when it is necessary to lift a certain group of pressure roller bodies 26 separately, it is only necessary to toggle the pressure roller trigger 41 to move the lower end of the pressure roller trigger 41 to the upper surface of the end of the pressure roller plate 23, so that the end of the pressure roller plate 23 rotates downward around the wheel plate shaft 24, that is, the pressure roller body 26 can be lifted, and at this time the tension spring 25 is stretched;

[0033] When a group of pressure roller bodies 26 needs to be pressed down, it is only necessary to pull the pressure roller trigger 41 to move the lower end of the pressure roller trigger 41 away from the upper surface of the pressure roller plate 23, and the stretched tension spring 25 is restored, driving the end of the pressure roller plate 23 to rotate upward around the wheel plate shaft 24, so that the pressure roller body 26 can be pressed down.

[0034] Furthermore, the linkage control mechanism 5 includes a rotating shaft 51 arranged inside the shell 21, and a rectangular rod 52 is inserted inside the rotating shaft 51. A triangular push block 53 is fixedly connected to the surface of the rotating shaft 51. When the triangular push block 53 is vertically downward, the pressure wheel body 26 is in a lifted state, and when the triangular push block 53 is tilted, the pressure wheel body 26 is in a pressed down state.

[0035] In this embodiment, when it is necessary to lift or press the pressure wheel body 26 at the same time, it can be adjusted through the linkage control mechanism 5. Specifically, when it is necessary to lift the pressure wheel body 26 at the same time, by rotating the rectangular rod 52, all the rotating shafts 51 and the triangular push block 53 are driven to rotate. When the triangular push block 53 is rotated to vertically downward, the triangular push block 53 causes the ends of all the pressure wheel plates 23 to rotate downward around the wheel plate shaft 24, that is, the pressure wheel body 26 can be lifted, and at this time the tension spring 25 is stretched;

[0036] When it is necessary to press down the pressure wheel body 26 at the same time, by rotating the rectangular rod 52, all the rotating shafts 51 and the triangular push block 53 are driven to rotate, so that the triangular push block 53 is rotated to an inclined state. At this time, the stretched tension spring 25 is reset, driving the end of the pressure wheel plate 23 to rotate upward around the wheel plate shaft 24, so that the pressure wheel body 26 can be pressed down.

[0037] Furthermore, the pressure regulating mechanisms 3 include a pressure roller pressure regulating lever 33, one end of which is rotatably connected to the shell 21 via a pressure regulating lever shaft 34, the middle part of the pressure roller pressure regulating lever 33 is rotatably connected to the pressure roller pressure regulating handle 31 via a pressure roller pressure regulating pin shaft 32, and the other end of the pressure roller pressure regulating lever 33 is fixedly connected to the upper end of the tension spring 25.

[0038] Furthermore, the surface of the pressure roller pressure regulating handle 31 is provided with a pressure regulating surface A and a pressure regulating surface B, and the vertical distance between the axis point of the pressure roller pressure regulating pin shaft 32 and the pressure regulating surface A is greater than the vertical distance between the axis point of the pressure roller pressure regulating pin shaft 32 and the pressure regulating surface B.

[0039] Furthermore, circular holes 6 adapted to the rotating shaft 51 are formed on both sides of the housing 21 , and both ends of the rotating shaft 51 are rotatably mounted inside the circular holes 6 .

[0040] In this embodiment, by providing a pressure adjustment mechanism 3, the pressure when the pressure wheel body 26 is lifted or pressed down can be adjusted;

[0041] When the pressure wheel body 26 is lifted alone, the pressure wheel pressure regulating handle 31 is rotated so that the pressure regulating surface A of the pressure wheel pressure regulating handle 31 contacts the housing 21. At this time, the pressure wheel pressure regulating lever 33 rotates upward around the pressure regulating lever shaft 34, thereby lengthening the tension spring 25 and increasing the tension of the tension spring 25. This is the pressure wheel body 26 being lifted alone and in high pressure state; in this state, the pressure wheel pressure regulating handle 31 is rotated so that the pressure regulating surface B of the pressure wheel pressure regulating handle 31 contacts the housing 21. At this time, the pressure wheel pressure regulating lever 33 rotates downward around the pressure regulating lever shaft 34, thereby contracting the tension spring 25 and reducing the tension of the tension spring 25. This is the pressure wheel body 26 being lifted alone and in low pressure state;

[0042] When the pressure roller bodies 26 are lifted at the same time, the pressure roller pressure regulating handle 31 is rotated so that the pressure regulating surface A of the pressure roller pressure regulating handle 31 contacts the housing 21. At this time, the pressure roller pressure regulating lever 33 rotates upward around the pressure regulating lever shaft 34, thereby lengthening the tension spring 25 and increasing the tension of the tension spring 25. This is the high-pressure state in which the pressure roller bodies 26 are lifted synchronously. In this state, the pressure roller pressure regulating handle 31 is rotated so that the pressure regulating surface B of the pressure roller pressure regulating handle 31 contacts the housing 21. At this time, the pressure roller pressure regulating lever 33 rotates downward around the pressure regulating lever shaft 34, thereby contracting the tension spring 25 and reducing the tension of the tension spring 25. This is the low-pressure state in which the pressure roller bodies 26 are lifted synchronously.

[0043] When the pressure roller body 26 is pressed down at the same time, the pressure roller pressure regulating handle 31 is rotated so that the pressure regulating surface A of the pressure roller pressure regulating handle 31 contacts the housing 21. At this time, the pressure roller pressure regulating lever 33 rotates upward around the pressure regulating lever shaft 34, thereby lengthening the tension spring 25 and increasing the tension of the tension spring 25. This is the high-pressure state in which the pressure roller body 26 is pressed down synchronously; in this state, the pressure roller pressure regulating handle 31 is rotated so that the pressure regulating surface B of the pressure roller pressure regulating handle 31 contacts the housing 21. At this time, the pressure roller pressure regulating lever 33 rotates downward around the pressure regulating lever shaft 34, thereby contracting the tension spring 25 and reducing the tension of the tension spring 25. This is the low-pressure state in which the pressure roller body 26 is pressed down synchronously;

[0044] Furthermore, a card slot 1 is provided on the surface of the shell 21, and a card block adapted to the card slot 1 is provided on the surface of the engraving machine frame, and the card slot 1 and the card block are plug-in assembled.
