[0036] The nozzle body 1 and the nozzle lower page 2 are connected together, and the arc surface 11 and the inclined surface 21 are connected, in the production operation process, the ink in the ink supply channel on the nozzle body 1 flows out through the ink outlet 22, and the flowed-out ink flows to the ink outlet 22 along the arc surface 11 and the inclined surface 21 under the action of the gravity of the ink itself and accumulates near the ink outlet 22, and when the ink accumulates to a certain height, the ink is conveniently taken away by the damping roller 3.
[0037] The ink outlet 22 is arranged at the lowest position of the arc surface 11 and the inclined surface 21, when the ink supply amount instantaneously exceeds the demand of the damping roller 3, the excessive ink flows back to the ink outlet 22 along the arc surface and the inclined surface due to the action of gravity, reenters the ink supply circulation system, effectively avoids ink leakage and overflow, reduces waste, can reduce environmental pollution caused by ink leakage and overflow, and can improve product quality and production efficiency.
[0038] The nozzle body 1 is designed as the arc surface 11, so that the nozzle body 1 is more fitted with the damping roller 3, and the ink transmission is more uniform.
[0039] Exemplarily, as shown in Figure 3 The inclined surface is a curved surface. Specifically, the inclined surface is an arc curved surface. In other embodiments, the inclined surface can also be a straight surface.
[0040] Optionally, the ink supply channel can also be provided through the nozzle lower page 2.
[0041] Further, the nozzle body 1 and the nozzle lower page 2 are detachably connected. Specifically, the nozzle body 1 and the nozzle lower page 2 are fastened and connected by fasteners, which are convenient to detach, facilitate cleaning of the groove 23, avoid impurities from being blocked in the ink outlet 22, and facilitate daily disassembly and regular cleaning of the ink nozzle.
[0042] In other embodiments, the nozzle body 1 and the nozzle lower page 2 can also be an integrally formed structure.
[0043] Further, the ink outlet 22 is a rectangular opening, and the length extension direction of the ink outlet 22 is parallel to the axial direction of the ink roller 3.
[0044] As shown in the drawings, the ink outlet 22 is in the shape of an elongated rectangle, and the distribution area of the ink after flowing out is large, so that the ink roller 3 can uniformly contact the ink flowing out of the ink outlet 22, and the ink uniformizing effect is better. Figure 4
[0045] Further, the nozzle lower page 2 is provided with a groove 23, the groove 23 and the nozzle body 1 surround the ink outlet 22, and the groove 23 is in communication with the ink supply channel.
[0046] As shown in the drawings, the groove 23 serves as a transition structure between the ink supply channel and the ink outlet 22, and can buffer the instantaneous pressure fluctuation of the ink flow. When the external pressure of the ink supply channel changes, the groove 23 can reduce the pressure impact by temporarily storing or releasing a small amount of ink, thereby avoiding the phenomenon of unstable ink jetting or ink breakage of the ink outlet 22.

[0047] Further, the groove 23 includes an ink inlet end and an ink outlet end, the ink inlet end is in communication with the ink supply channel, the ink outlet end is in communication with the ink outlet 22, and the width of the groove 23 gradually increases in the direction from the ink inlet end to the ink outlet end.
[0048] The ink flowing out of the ink supply channel first flows into the groove 23 through the ink inlet end, and then disperses along the inner wall of the groove 23 to make the ink in a gradually expanding state. Since the flow rate of the ink flowing into the ink inlet end of the groove 23 is large, by expanding the lateral diffusion space of the ink, the groove 23 makes the flow rate of the ink uniform before the ink flows out of the ink outlet end, thereby avoiding the phenomenon of uneven ink flow of the ink outlet 22 and affecting the ink uniformizing effect of the ink roller 3.
[0049] The ink flowing out of the ink outlet 22 through the ink outlet end can be uniformly distributed in the width direction of the ink outlet 22, so that the ink roller 3 can contact a larger area of the ink, the coverage of the ink on the ink roller 3 is larger, and the ink uniformizing effect is significantly improved.
[0050] As shown in the drawings, the ink outlet 22 is in the shape of an elongated rectangle, and the distribution area of the ink after flowing out is large, so that the ink roller 3 can uniformly contact the ink flowing out of the ink outlet 22, and the ink uniformizing effect is better. Figure 5 As shown, the width of the out end of the groove 23 is greater than the width of the ink outlet 22, the wider groove 23 can provide a larger lateral flow space, so that the ink flow rate in the groove 23 is uniform, and the ink flowing into the ink outlet 22 is more uniform.
[0051] Further, from the direction of the nozzle body 1 to the nozzle lower page 2, the width of the arc surface 11 and the inclined surface 21 gradually decreases.
[0052] In combination Figure 2 , Figure 4 As shown, the nozzle lower page 2 is designed to be narrowed, according to the principles of fluid mechanics and aerodynamics, when the ink fluid moves forward, the ink at the edge will move along the boundary line, and finally be taken away by the ink roller 3 at the narrow outlet end of the nozzle lower page 2, which can effectively prevent the ink fluid from overflowing when moving forward, reduce environmental pollution, greatly improve product quality, and thus improve production efficiency.
[0053] As shown Figure 1 , 2 The embodiment of the utility model provides a roll forming machine, ink pump, ink roller 3 and above-mentioned ink nozzle, ink nozzle fixed mounting is in the frame, ink pump fixed mounting is in the frame, for to ink channel delivery ink, ink roller 3 rotation installs in the frame, ink roller 3 is located above ink nozzle and can abut on arc surface 11 to make ink flow to ink roller 3 through ink outlet 22.
[0054] The ink pump delivers ink to the ink supply channel, and then the ink flows into the groove 23 from the ink supply channel, and then uniformly flows into the ink outlet 22 after lateral diffusion through the groove 23. The accumulated ink after flowing out is accumulated on the arc surface on both sides of the ink outlet 22, and after accumulating a certain thickness, it can be taken away by the ink roller 3 to complete the ink uniformizing process, which can effectively prevent ink from leaking and overflowing, reduce waste, not only can reduce environmental pollution caused by ink leakage and overflow, but also can improve product quality, and thus improve production efficiency.
[0055] Further, a first gap is provided between the ink roller 3 and the ink outlet 22, and the radial dimension of the first gap is 0.01mm-0.10mm.
[0056] As shown Figure 1 , the ink roller 3 is located above the arc surface 11, and the radial dimension of the first gap between the ink roller 3 and the ink outlet 22 is 0.01mm-0.10mm, when the ink accumulation thickness exceeds the preset value, it will be automatically taken away by the ink roller 3, so that the overflow phenomenon will not occur, by reducing the ink accumulation thickness, it can effectively prevent the ink from leaking and overflowing due to accumulation, so as to affect the product quality.
[0057] Further, the width of the ink roller 3 is L1, the minimum width of the nozzle lower page 2 is L2, and L1>L2.
[0058] In combination Figure 2 , Figure 4 The width of the ink roller 3 is between the nozzle body 1 and the nozzle lower page 2, and the ink flows out through the ink outlet 22 and moves to the outlet end of the nozzle lower page 2 according to the principles of fluid mechanics and aeromechanics, and accumulates at the outlet end. Since the width of the ink roller 3 is greater than the width of the outlet end of the nozzle lower page 2, that is, the ink roller 3 can cover the ink at the outlet end of the nozzle lower page 2, the ink can be carried away by the ink roller 3 when it accumulates to a certain thickness, effectively preventing the ink from leaking out.
