[0031] refer to Figure 1 According to an embodiment of the present invention, a spraying device includes a mounting frame 100, a bearing structure 200, a pressing structure 300 and a position adjustment structure 400. The mounting frame 100 is used to connect with the frame of the circular knife machine; the bearing structure 200 is used to place the release agent bottle; the pressing structure 300 is arranged on the bearing structure 200, and the pressing structure 300 includes a first driver 310 and a pressing block 320. The first driver 310 is connected to the pressing block 320, and the first driver 310 can drive the pressing block 320 to move along the The position adjusting structure 400 is provided on the mounting frame 100 and is connected to the supporting structure 200. The position adjusting structure 400 is used to adjust the position of the supporting structure 200 in the second direction. The second direction is spaced apart from the first direction by a certain angle so that the release agent sprayed by the release agent bottle can be sprayed to different axial positions of the knife roller, wherein the second direction is parallel to the axial direction of the knife roller.

[0032] It should be noted that the release agent bottle includes a bottle body and a nozzle. The nozzle is arranged on the bottle body and a spray button is arranged on the nozzle head. Under the action of external force, pressing the spray button can make the release agent in the release agent bottle spray out from the nozzle.

[0033] During the operation of the spraying device of the present application, a release agent bottle is placed in the supporting structure 200. Since the first driver 310 is connected to the pressing block 320, the pressing block 320 is driven by the first driver 310 to move in the first direction, and the pressing block 320 abuts against the spray button of the release agent bottle placed in the supporting structure 200. The spray button is pressed by the pressing block 320, so that the release agent bottle can continuously spray the release agent. Since the supporting structure 200 is connected to the position adjustment structure 400, the position of the supporting structure 200 in the second direction is adjusted by the position adjustment structure 400, so that the release agent can be sprayed on different positions of the knife roller in its own axial direction. From the above operation process, it can be seen that the spraying device of the present application can automatically spray the release agent, further improving production efficiency.

[0034] In some embodiments of the present invention, the supporting structure 200 includes a mounting plate 210 and a supporting member 220. One end of the supporting member 220 is hinged to the mounting plate 210, and the other end of the supporting member 220 is detachably connected to the mounting plate 210. The mounting plate 210 and the supporting member 220 jointly define a receiving groove 200a. The receiving groove 200a is used to receive the bottom of the release agent bottle. The mounting plate 210 is connected to the position adjustment structure 400. For example, Figure 1 As shown, the supporting structure 200 includes a mounting plate 210 and a supporting member 220, the supporting member 220 has a first end 221 and a second end 222 relative to each other, the first end 221 is hinged to the mounting plate 210, and the second end 222 is connected to the mounting plate 210 by a locking buckle, the mounting plate 210 and the supporting member 220 jointly define a receiving groove 200a, the receiving groove 200a is used to receive the bottom of the release agent bottle, and the mounting plate 210 is connected to the position adjustment structure 400.

[0035] It can be understood that by disconnecting the second end 222 from the mounting plate 210 and rotating the supporting member 220 to move the second end 222 away from the mounting plate 210, the staff can place the bottom of the release agent bottle in the receiving groove 200a of the supporting member 220 without hindrance, and then rotate the supporting member 220 to make the second end 222 close to the mounting plate 210, and connect the supporting member 220 and the mounting plate 210 through a lock buckle. At this time, the release agent bottle can be stably placed in the supporting structure 200.

[0036] In some other embodiments of the present invention, in addition to being connected by the lock snap connection in the above embodiments, the second end 222 of the carrier 220 and the mounting plate 210 can also be connected by a pin.

[0037] In some embodiments, the supporting structure 200 further includes a first threaded fastener, and the mounting plate 210 is provided with a plurality of mounting through-hole groups arranged along a first direction, each mounting through-hole group including at least one mounting through-hole 210a, and the first threaded fastener passes through the mounting through-hole 210a of one of the mounting through-hole groups and is threadedly connected to the position adjustment structure 400. For example, Figure 1 As shown, the supporting structure 200 further includes a first threaded fastener. The mounting plate 210 is provided with a plurality of mounting through-hole groups arranged along the first direction. Each mounting through-hole group includes two mounting through-holes 210a arranged along the second direction. The first threaded fastener can be selectively inserted through the mounting through-holes 210a of one of the mounting through-hole groups and threadedly connected to the position adjustment structure 400. It will be understood that since the mounting plate 210 is provided with a plurality of mounting through-hole groups arranged along the first direction, the position of the supporting structure 200 in the first direction can be adjusted by selectively inserting the first threaded fastener into one of the mounting through-holes 210a.

[0038] refer to Figure 1 In some embodiments of the present invention, the pressing structure 300 further includes a fixed plate 330. The first driver 310 is a cylinder, which is disposed on the fixed plate 330. The fixed plate 330 is adjustably disposed on the mounting plate 210 along a first direction. It is understood that the stroke of the cylinder is fixed. Since the pressing block 320 is connected to the cylinder, when the cylinder reaches its maximum stroke, the position of the pressing block 320 relative to the cylinder is fixed. Since the cylinder is disposed on the fixed plate 330, which is disposed on the mounting plate 210, when the cylinder reaches its maximum stroke, the operator can adjust the position of the pressing block 320 in the first direction by adjusting the position of the fixed plate 330 on the mounting plate 210 in the first direction. This can further adjust the pressing depth of the spray button by the pressing block 320 in the first direction, thereby adjusting the amount of release agent sprayed.

[0039] like Figure 1 As shown, in one embodiment, the spraying device further includes a second threaded fastener. The mounting plate 210 is provided with an elongated hole 210b extending in the first direction. The second threaded fastener slidably passes through the elongated hole 210b and is threadedly connected to the fixing plate 330. It is understood that the position of the second threaded fastener in the first direction can be adjusted by sliding the second threaded fastener in the elongated hole 210b. Since the second threaded fastener is threadedly connected to the fixing plate 330, the position of the fixing plate 330 in the first direction can be adjusted.

[0040] refer to Figure 1 and Figure 2In some embodiments of the present invention, the position adjustment structure 400 includes a mounting seat 410, a slider 420, and a second actuator 430. The slider 420 is slidably disposed on the mounting seat 410 in a second direction. The second actuator 430 is connected to the slider 420 and is configured to drive the slider 420 to slide in the second direction. The support structure 200 is connected to the slider 420. It is understood that by driving the slider 420 to slide in the second direction on the mounting seat 410 via the second actuator 430, the slider 420, because it is connected to the support structure 200, can drive the release agent bottle placed on the support structure 200 to slide in the second direction, thereby allowing the release agent sprayed from the release agent bottle to be sprayed onto different axial positions of the knife roller. Specifically, the second actuator 430 is a rodless cylinder.

[0041] In some embodiments, a limit block 411 is slidably provided on the mounting seat 410 along the second direction, and the limit block 411 is used to limit the slider 420 in the second direction. Figure 1 and Figure 2 As shown, two limit blocks 411 are slidably provided on the mounting seat 410 along the second direction, and the slider 420 is disposed between the two limit blocks 411. It is understood that the limit blocks 411 provided on the mounting seat 410 limit the sliding movement of the slider 420 on the mounting seat 410, thereby limiting the sliding range of the release agent bottle on the supporting structure 200, and further controlling the spraying range of the release agent at different axial positions on the knife roller.

[0042] It should be understood that the number of the upper limit blocks 411 of the mounting base 410 can be determined according to actual needs and is not limited to two in the above embodiment.

[0043] In a further embodiment of the present invention, a buffer member 411a is provided on the end surface of the limit block 411 near the slider 420. It is understood that by providing the buffer member 411a on the limit block 411, the impact force between the slider 420 and the limit block 411 is reduced, thereby reducing the possibility of deformation of the slider 420 due to collision with the limit block 411.

[0044] refer to Figure 1In some embodiments of the present invention, the mounting frame 100 includes a connecting block 110, a rotating rod 120, and a fixed block 130. The connecting block 110 is rotatably connected to the rotating rod 120 about a first rotation axis 101, and the rotating rod 120 is rotatably connected to the fixed block 130 about a second rotation axis 102. The first rotation axis 101 and the second rotation axis 102 are arranged parallel to each other. The connecting block 110 is connected to the position adjustment structure 400, and the fixed block 130 is used to connect to the frame of the circular knife machine. It is understood that by rotating the connecting block 110 in a forward direction about the first rotation axis 101 and rotating the rotating rod 120 in a reverse direction about the second rotation axis 102, the position of the supporting structure 200 on the position adjustment structure 400 can be adjusted in the first direction, and at this time, the release agent spraying angle of the release agent bottle on the supporting structure 200 remains unchanged.

The spraying device is arranged on one side of the knife roller, and the axial direction of the knife roller is parallel to the second direction. The release agent in the release agent bottle is automatically sprayed at different positions in the axial direction of the knife roller through the spraying device.

[0046] In some embodiments of the present invention, the circular knife machine of the present application can implement the following working method when working, wherein the working method includes but is not limited to the following steps:

[0047] Step S100: placing a release agent bottle on the supporting structure 200;

[0048] Step S200: The first driver 310 drives the pressing block 320 to approach and press the spray button of the release agent bottle in a first direction, so that the release agent bottle continuously sprays the release agent;
