Description

Technical Field

[0001] This utility model belongs to the field of printing machine drying and curing technology, specifically, it relates to a fire prevention device for curing lamps. Background Technology

[0002] Currently, after inkjet printing on paper, roll-to-roll printing presses (such as gravure, flexographic, and roll-to-roll digital printing presses) require curing lamps to dry and cure the paper. However, in the event of a sudden machine stoppage, the curing lamps will continue to irradiate the same spot on the paper for an extended period. Because the curing lamps operate at high temperatures, even after being turned off, the residual heat can cause the paper or other flammable materials at the irradiated location to overheat and scorch, potentially igniting a fire and leading to a production safety accident. Therefore, how to prevent the heat from the curing lamps from causing the paper to overheat and scorch during abnormal paper transport has become a pressing problem for those in the field.

[0004] The optical axis has a first mounting component and a second mounting component at each end, which are suitable for mounting the optical axis at the installation position by means of the first mounting component and the second mounting component;

[0005] One side of the shutter stop is connected to the optical axis via a connecting assembly. The shutter stop is suitable for being placed next to the curing lamp via the optical axis.

[0006] The drive unit is connected to the optical axis drive and is suitable for driving the optical axis to move along its body length so that the optical axis can drive the shutter stop to move between the curing lamp and the paper for heat insulation.

[0007] In one possible implementation, the shutter stop includes a connecting plate and a blocking plate;

[0008] One end of the connecting plate is fixedly connected to the shielding plate, and the other end of the connecting plate is connected to the connecting assembly.

[0013] In one possible implementation, it further includes: a driving element, which is fixedly connected to the optical axis, and the driving end of the driving unit is connected to the driving element to drive the optical axis to move through the driving element.

[0014] In one possible implementation, the drive unit is disposed inside the cavity of the first mounting member; the drive unit is an electromagnet.

[0039] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0040] Figure 1 This invention provides a schematic diagram of the main structure of a fire-prevention device for curing lamps. (See attached diagram.) Figure 1As shown, this application provides a fire-prevention device for a curing lamp. The device includes a shutter baffle 100, an optical axis 300, and a drive unit 400. The optical axis 300 has a first mounting member 500 and a second mounting member 600 at its two ends, respectively, suitable for mounting the optical axis 300 to the desired position via the first mounting member 500 and the second mounting member 600. One side of the shutter baffle 100 is connected to the optical axis 300 via a connecting assembly 200, and the shutter baffle 100 is suitable for being positioned beside the curing lamp 800 via the optical axis 300. The drive unit 400 is drivenly connected to the optical axis 300, suitable for driving the optical axis 300 to move along its length, so that the optical axis 300 can move the shutter baffle 100 to the space between the curing lamp 800 and the paper for heat insulation.

[0041] The fire prevention device for the curing lamp of this application involves placing the shutter baffle 100 next to the curing lamp 800. When abnormal situations such as paper stopping occur, the drive unit 400 can quickly drive the optical axis 300 to move the shutter baffle 100 between the curing lamp 800 and the paper. The shutter baffle 100 can isolate the residual heat of the curing lamp 800, thereby preventing the area of ​​the paper that has been exposed to the curing lamp 800 for a long time from being scorched and ignited due to the residual heat of the curing lamp 800.

[0042] See Figure 1 As shown, the shutter stop 100 includes a connecting plate 110 and a blocking plate 120. One end of the connecting plate 110 is fixedly connected to the blocking plate 120, and the plane of the connecting plate 110 is perpendicular to the plane of the blocking plate 120. The other end of the connecting plate 110 is connected to the connecting assembly 200.

[0043] The main body of the connecting plate 110 is a rectangular plate structure, and the main body of the shielding plate 120 is also a rectangular plate structure. The area of ​​the shielding plate 120 is larger than the irradiation area of ​​the curing lamp 800 so as to completely block the irradiation window of the curing lamp 800, thereby achieving effective heat insulation.

[0044] When the equipment is operating normally, the shutter stop 100 is positioned beside the curing lamp 800 without obstructing its illumination. In case of malfunction, the optical axis 300 moves the shutter stop 100 between the curing lamp 800 and the paper, completely blocking the light-emitting window of the curing lamp 800. It should also be noted that when the baffle 120 is moved directly below the curing lamp 800, the distance between the baffle 120 and the curing lamp 800 should be 3-10 mm, preferably 5 mm, to ensure optimal blocking effect of the shutter stop 100.

[0045] Furthermore, in one possible implementation, see [link to relevant documentation]. Figure 3As shown, a first fixing hole 111 is provided on the surface of the connecting plate 110. The first fixing hole 111 is suitable for bolting the shutter stop 100 to the connecting assembly 200. The main body of the first fixing hole 111 is an elongated circular hole, which is suitable for fine-tuning the installation height of the connecting plate 110, thereby adjusting the distance between the baffle plate 120 and the curing lamp 800.

[0046] In one possible implementation, the shutter stop 100 can be made of materials such as aluminum alloy or stainless steel that can block heat radiation.

[0047] In one possible implementation, see [link to relevant documentation] Figures 2 to 3 As shown, the connecting assembly 200 includes a first slider 210, which is sleeved on the optical axis 300. The connecting plate 110 is connected to the outer wall of the first slider 210, and the position of the shutter stop 100 on the optical axis 300 can be adjusted by the first slider 210.

[0048] See Figure 3 As shown, the side of the first slider 210 connected to the connecting plate 110 is a plane, and a first connecting hole 211 is provided on the plane. The bolt connects the shutter stop 100 and the connecting assembly 200 through the first fixing hole 111 and the first connecting hole 211.

[0049] Furthermore, see Figures 2 to 3 As shown, the connecting assembly 200 also includes a locking screw 220. The first slider 210 has a threaded hole that matches the locking screw 220. One end of the locking screw 220 passes through the threaded hole and abuts against the optical axis 300. The locking screw 220 is used to prevent the first slider 210 from sliding on its own and causing the shutter stop 100 to shift position.

[0050] It should also be noted that one end of the locking screw 220 is equipped with a wrench 230, which is used to rotate the locking screw 220. Loosening the locking screw 220 by the wrench 230 allows the first slider 210 to move the shutter stop 100 along the optical axis 300. Once the shutter stop 100 has moved to a preset position, the locking screw 220 is tightened by the wrench 230 to fix the shutter stop 100 in place.

[0051] Further, see Figure 1 As shown, the optical axis 300 has a first mounting member 500 and a second mounting member 600 at both ends, respectively, to mount the optical axis 300 to the installation position. The main body of the optical axis 300 is a round rod structure, and the optical axis 300 is made of a lightweight material, such as a surface-hardened aluminum alloy optical axis. It should be noted that the optical axis 300 can also be selected from other guide rails that can achieve rapid movement response.

[0052] In one possible implementation, see [link to relevant documentation] Figures 4 to 5 As shown, both the first mounting member 500 and the second mounting member 600 have a cuboid structure and an inner cavity. The first mounting member 500 has a through hole 501 on the side connected to the optical axis 300, and the through hole 501 matches the drive unit 400 so that the drive unit 400 can enter the inner cavity of the first mounting member 500 through the through hole 501.

[0053] Meanwhile, both the first mounting component 500 and the second mounting component 600 have mounting plates 510 fixedly installed on the side opposite to the optical axis 300, and the mounting plates 510 have first mounting holes 511, so that the first mounting component 500 and the second mounting component 600 can be installed in the position to be installed through the first mounting holes 511. Furthermore, "cross-shaped" plate-shaped fasteners 520 are fixedly installed between the mounting plate 510 of the first mounting component 500 and the first mounting component 500, and between the mounting plate 510 of the second mounting component 600 and the second mounting component 600, to enhance the stability of the device.

[0054] It should also be noted that the first mounting member 500 and the second mounting member 600 each have a second fixing hole 530 on their opposite sides, which is suitable for the optical axis 300 to pass through, so that both ends of the optical axis 300 can pass through the second fixing hole 530 into the first mounting member 500 and the second mounting member 600, thereby installing the optical axis 300 in the position to be installed.

[0055] In one possible implementation, the two ends of the optical axis 300 are respectively inserted into the cavities of the first mounting member 500 and the second mounting member 600 through the second fixing holes 530, and linear bearings 540 are provided between the two ends of the optical axis 300 and the first mounting member 500 and the second mounting member 600.

[0056] Among them, see Figure 6 As shown, the linear bearing 540 is fixedly mounted on the window of the second fixing hole 530. Both ends of the optical axis 300 pass through the inner ring of the linear bearing 540 and into the cavity of the first mounting member 500 and the second mounting member 600. It should be noted that the linear bearing 540 is used to reduce friction and improve the smoothness of movement when the optical axis 300 moves.

[0057] It should also be noted that the linear bearing 540 is provided with a second mounting hole 541, and the first mounting member 500 and the second mounting member 600 are provided with a third mounting hole 610 corresponding to the second mounting hole 541. The linear bearing 540 is fixed to the window of the second fixing hole 530 by using bolts passing through the second mounting hole 541 and the third mounting hole 610.

[0058] In one possible implementation, see [link to relevant documentation] Figure 10As shown, the drive unit 400 is disposed inside the first mounting member 500 so as to drive the optical axis 300 to move along its body length direction, thereby driving the shutter stop 100 to move between the curing lamp 800 and the paper for heat insulation.

[0059] Also see Figure 7 As shown, in one possible implementation, a drive member 700 is also included, which is fixedly connected to the optical axis 300. The drive end of the drive unit 400 is connected to the drive member 700 to drive the optical axis 300 to move through the drive member 700.

[0060] In one possible implementation, see [link to relevant documentation] Figures 8 to 9 As shown, the driving component 700 includes a second slider 710 and a connecting component 720. The second slider 710 is fixedly connected to the connecting component 720. The connecting component 720 has a cuboid structure and an opening facing the second mounting component 600. The second slider 710 is fixedly sleeved on the optical axis 300, and the side of the second slider 710 connected to the connecting component 720 is a plane with a second connecting hole 711. A corresponding third connecting hole 721 is provided on the side of the connecting component 720 connected to the second slider 710, so that the connecting component 720 and the second slider 710 are fixedly connected through the second connecting hole 711 and the third connecting hole 721.

[0061] Furthermore, the drive unit 400 is connected to the drive member 700 via a screw 730. A spiral hole 722 is provided on the side plane of the connector 720 facing the first mounting member 500, so that the screw 730 passes through the spiral hole 722 to fix the drive member 700 and the drive unit 400, thereby causing the drive unit 400 to drive the drive member 700 to move, and in turn, drive the optical axis 300 fixedly connected to the drive member 700 to move.

[0062] In one possible implementation, see [link to relevant documentation] Figure 10 As shown, a spring 410 is fixedly installed on the side of the drive unit 400 opposite to the drive member 700. The spring 410 is sleeved on the connecting rod 411, and one end of the connecting rod 411 is fixedly connected to the drive unit 400. The spring 410 is used to reset the drive unit 400.

[0063] In one possible implementation, the drive unit 400 is disposed inside the cavity of the first mounting member 500; wherein the drive unit 400 can use an electromagnet. That is, when an abnormal situation occurs in which the paper stops feeding, the machine is turned off and the electromagnet is energized at the same time. At this time, the electromagnet generates linear displacement and drives the optical axis 300, which is fixedly connected to the drive member 700, to move, thereby moving the shutter stop 100 to the space between the curing lamp 800 and the paper for heat insulation. When the power supply to the electromagnet is stopped, the spring 410 resets the drive unit 400, thereby restoring the shutter stop 100 to the side of the curing lamp 800.

[0064] In another possible implementation, the drive unit 400 can also use a cylinder, which is installed inside the cavity of the first mounting member 500, and the pushing end of the cylinder passes through the first mounting member 500 and is connected to the drive member 700, so that when the pushing end of the cylinder moves, it drives the optical axis 300, which is fixedly connected to the drive member 700, to move along its length, thereby driving the shutter stop 100 to move between the curing lamp 800 and the paper for heat insulation.

[0065] It should be noted that the drive unit 400 preferably uses an electromagnet, which can react within milliseconds, providing the fastest response time and minimizing the risk of fire. Specifically, when the door stop is heavy, the drive unit 400 can be driven by a cylinder; when electricity or pneumatics are not feasible in the application, a spring can be used, with no particular limitation.

[0066] In one possible implementation method Figure 11 This diagram illustrates the positional relationship between the fire-prevention device for the curing lamp and the curing lamp 800. (See attached diagram.) Figure 11 As shown, there are two optical axes 300, and two corresponding second fixing holes 530 are also provided on the first mounting member 500 and the second mounting member 600.

[0067] Meanwhile, in one possible implementation, see [link to relevant documentation]. Figure 11 As shown, each optical axis 300 is provided with two or more shutter baffles 100, and the distance between two adjacent shutter baffles 100 is suitable to be equal to the distance between two adjacent curing lamps 800 on the same straight line. This is suitable so that when the drive unit 400 drives the optical axis 300 to move along its body length direction, the multiple shutter baffles 100 fixedly connected to the optical axis 300 can move simultaneously to the side between the curing lamp 800 and the paper for heat insulation.

[0068] It should be noted that, Figure 11 The fire prevention device for the curing lamp 800 is installed in the position to be installed by the first mounting part 500 and the second mounting part 600. At the same time, the drive part 400 provided in the inner cavity of the first mounting part 500 drives the optical axis 300 fixedly connected to the drive part 700 to move. This causes multiple shutter baffles 100 connected to the optical axis to move simultaneously between the adjacent curing lamp 800 and the paper, thereby ensuring that multiple curing points on the paper are simultaneously insulated from heat. This can effectively prevent the paper from being scorched or even catching fire due to the residual heat of the curing lamp 800.

[0069] Therefore, this application provides a fire prevention device for a curing lamp. This device includes a shutter baffle 100, which is moved to insulate the paper from the curing lamp 800 by moving it between the lamp and the paper. This prevents the shutter baffle 100 from blocking the curing lamp 800's illumination window in the event of a paper feed interruption, thus preventing the residual heat from the curing lamp 800 from causing the paper to scorch and catch fire. Simultaneously, this application also includes an optical axis 300 and a drive unit 400. The optical axis 300 positions the shutter baffle 100 beside the curing lamp 800. In the event of a paper feed interruption, the drive unit 400 can drive the optical axis 300 to move along its length, thereby moving the shutter baffle 100 between the paper and the curing lamp 800 for heat insulation. Furthermore, the shutter baffle 100 of this application has a short moving distance, a small size, and requires little space for installation, making it easy to place. Moreover, the shutter stop 100 of this application can react within milliseconds, allowing the shutter stop 100 to quickly move between the curing lamp 800 and the paper to insulate against heat, effectively blocking heat radiation and reducing the risk of fire.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
