[0029] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0030] First, the X direction, Y direction and Z direction mentioned in the embodiment of the present application are shown in the attached drawings. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The marked directions, where the X, Y, and Z directions intersect with each other.

[0031] like Figure 1-Figure 4 As shown, according to the first aspect of the embodiment of the present application, a roller gap adjustment device is provided, comprising a plurality of adjustment roller mechanisms 1 arranged along the X direction, wherein the adjustment roller mechanism 1 comprises a roller assembly 11 and an adjustment assembly 12; the roller assembly 11 comprises a first pressure roller 111, and the axis of the first pressure roller 111 intersects with the axis in the Z direction; the adjustment assembly 12 is connected to the roller assembly 11, and the adjustment assembly 12 can drive the roller assembly 11 to move in the Z direction to adjust the height difference between the first pressure rollers 111 of two adjacent adjustment roller mechanisms 1.

[0032] like Figure 1 and Figure 2 As shown, the roller gap adjusting device includes a plurality of adjusting roller mechanisms 1, and the plurality of adjusting roller mechanisms 1 are arranged along the X direction, wherein the plurality of adjusting roller mechanisms 1 can be arranged at intervals along the X direction, or the plurality of adjusting roller mechanisms 1 can be arranged adjacent to each other along the X direction.

[0033] The adjusting roller mechanism 1 includes a roller assembly 11 and an adjusting assembly 12; wherein, the roller assembly 11 is connected to the adjusting assembly 12, and the adjusting assembly 12 can drive the roller assembly 11 to move along the Z direction; the roller assembly 11 includes a first pressure roller 111, and when the adjusting assembly 12 drives the roller assembly 11 to move in the Z direction, it also drives the first pressure roller 111 to move in the Z direction.

[0034] To further illustrate, the axis of the first pressure roller 111 intersects with the axis of the Z direction. Therefore, when the adjustment component 12 drives the roller component 11 to move along the Z direction, the height difference between the axes of the first pressure rollers 111 of two adjacent adjustment roller mechanisms 1 can be adjusted, so the distance between the roller gaps between the first pressure rollers 111 of two adjacent adjustment roller mechanisms 1 can also be adjusted.

[0035] Therefore, the roller gap adjustment device of the present application, such as Figure 2 As shown, by adjusting the height difference between the axes of the first pressing rollers 111 of two adjacent adjusting roller mechanisms 1 in the Z direction, the spacing of the roller gaps between the two adjacent first pressing rollers 111 can be adjusted; in this embodiment, the adjustment of the roller gap between the two adjacent first pressing rollers 111 will not be subject to spatial restrictions, and the adjusted roller gap gap is more stable and reliable, thereby achieving a better coating effect.

[0036] Among them, the roller gap adjustment device of the present application has no restriction on the diameter of the first pressing roller 111 and has high compatibility.

[0037] Among them, if the spacing of the roller gap between two adjacent first pressing rollers 111 is to be minimized, the axes of the two adjacent first pressing rollers 111 are located at the same height in the Z direction.

[0042] Further explanation, such as Figure 3 As shown, the adjustment assembly 12 includes a hydraulic cylinder, the driving end of which is a piston rod of the hydraulic cylinder. The piston rod is connected to the first mounting bracket 112. By driving the piston rod to move in the Z direction, the first mounting bracket 112 is driven to move in the Z direction, thereby adjusting the height of the first pressing roller 111 in the Z direction. Among them, the roller assembly 11 is driven by a hydraulic cylinder, which has a simple structure and low cost.

[0043] Specifically, if Figure 3 As shown, the first mounting bracket 112 also includes a connecting plate 1123, one end of the connecting plate 1123 is connected to the first mounting plate 1121, and the other end of the connecting plate 1123 is connected to the second mounting plate 1122.

In the Z direction, the hydraulic cylinder is located below the connecting plate 1123, so the driving end of the hydraulic cylinder is connected to the connecting plate 1123, so that the hydraulic cylinder drives the first mounting bracket 112 to move along the Z direction in the Z direction; the structure is simple, easy to install, and occupies less space.

[0044] In an optional embodiment, the roller gap adjustment device also includes a frame 3, and the first mounting bracket 112 is provided on the frame 3 and is slidably connected to the frame 3; when the first mounting bracket 112 moves along the Z direction, the first mounting bracket 112 can slide in the Z direction relative to the frame 3, and the frame 3 can provide a support and limiting effect for the first mounting bracket 112, so that the first mounting bracket 112 is more stable during the movement and avoids deflection.

[0045] Specifically, the frame 3 includes a third mounting plate 31 and a fourth mounting plate 32, and the third mounting plate 31 and the fourth mounting plate 32 are spaced apart along the Y direction. The length direction of the third mounting plate 31 and the fourth mounting plate 32 is the X direction, and multiple adjusting roller mechanisms 1 are arranged between the third mounting plate 31 and the fourth mounting plate 32 along the X direction; taking the connection between an adjusting roller mechanism 1 and the frame 3 as an example, the first mounting plate 1121 is slidably connected to the third mounting plate 31, and the second mounting plate 1122 is slidably connected to the fourth mounting plate 32, so that the adjusting roller mechanism 1 and the frame 3 are slidably connected along the Z direction.

[0050] The adjustment assembly 12 includes a motor, a lead screw, and a nut seat. The axis of the lead screw is parallel to the axis in the Z direction, and the output end of the motor is connected to the lead screw. In other words, the output shaft of the motor is connected to the lead screw, which can be connected to the lead screw via a coupling. The outer wall of the lead screw has external threads, and the nut seat has a threaded hole. The threaded hole in the nut seat engages with the threaded outer wall of the lead screw. When the motor drives the lead screw to rotate about its own axis, the nut seat can move in the Z direction. The first mounting bracket 112 is connected to the nut seat, so the first mounting bracket 112 also moves in the Z direction, thereby adjusting the height of the first pressure roller 111 in the Z direction. In this embodiment, the adjustment assembly 12 has higher adjustment accuracy, can achieve small distance adjustment, and has a simple structure and low cost.

[0051] Specifically, the first mounting plate 1121 is connected to the nut seat, or the second mounting plate 1122 is connected to the nut seat.

The frame 3 can provide support and limit for the first mounting bracket 112, thereby making the first mounting bracket 112 more stable during movement and preventing deflection.

[0053] Specifically, if Figure 4 As shown, the frame 3 includes a third mounting plate 31 and a fourth mounting plate 32, and the third mounting plate 31 and the fourth mounting plate 32 are spaced apart along the Y direction. The length direction of the third mounting plate 31 and the fourth mounting plate 32 is the X direction, and multiple adjusting roller mechanisms 1 are arranged between the third mounting plate 31 and the fourth mounting plate 32 along the X direction; taking the connection between an adjusting roller mechanism 1 and the frame 3 as an example, the adjusting component 12 is arranged on the third mounting plate 31, the first mounting plate 1121 is slidably connected to the third mounting plate 31, and the second mounting plate 1122 is slidably connected to the fourth mounting plate 32, so that the adjusting roller mechanism 1 is slidably connected to the frame 3 along the Z direction.
