Description

Technical Field

[0001] This utility model belongs to the field of ink curing technology, specifically relating to a printing ink curing device. Background Technology

[0002] After printing or coating, UV ink is irradiated with ultraviolet light, causing the monomer molecules in the ink to undergo photopolymerization and quickly solidify to form a hard film that adheres to the surface of the printed material.

[0003] Chinese patent document CN219236524U discloses a printing ink curing device, which uses a second motor to drive an adjusting block to swing left and right, so that the adjusting block drives a moving frame to move back and forth via a connecting rod, and the moving frame drives an ultraviolet lamp to move back and forth. The back and forth movement of the ultraviolet lamp makes the printed material cure evenly, resulting in a better curing effect.

[0004] However, in the existing technology, when curing printed materials of different sizes, the coverage range of the light emitted by the existing curing device is fixed, and there is still a large distance when the two sets of ultraviolet lamps move towards each other to the limit position. This is not conducive to the full curing of the printed materials, and it will cause unnecessary energy consumption when curing small printed materials. Therefore, a printing ink curing device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a printing ink curing device.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A printing ink curing device includes a feeding component that can laterally convey printed matter to be cured in the device, a curing component that can meet the curing needs of printed matter of different sizes without excessive energy consumption, and a driving component that can make the curing component operate as needed.

[0008] The curing assembly includes an irradiation element that generates high-intensity ultraviolet light and illuminates the printed material, an oscillating element that can drive the irradiation element to fully cover the printed material, and a loading element that can limit the range of motion of the oscillating element.

[0009] The loading component includes a receiving box fixedly installed above the feeding assembly, and a carrier frame is fixedly installed inside the receiving box;

[0010] The swing component includes a movable frame movably installed inside the carrier, a rack fixedly connected to the movable frame, bearing seats fixedly installed on both sides of the carrier, a rotating shaft movably connected between the bearing seats, and a gear fixedly connected to the outer side of the rotating shaft.

[0011] Preferably, the loading component also includes limiting rods fixedly installed on both sides of the carrier frame.

[0012] Preferably, the irradiation element includes a lamp holder fixedly connected between movable frames of the same height, and a UV lamp is fixedly installed inside the lamp holder.

[0013] Preferably, the rack and pinion are meshed together.

[0014] Preferably, the carrier and the limiting rod are slidably connected to the movable frame, and the bearing seat is rotatably connected to the rotating shaft.

[0015] Preferably, the drive assembly includes a T-shaped frame fixedly connected above the higher movable frame.

[0016] The beneficial effects of this utility model are: it facilitates the synchronous movement of two sets of irradiation elements by using two sets of movable frames set at different heights and with a certain misalignment, so that the stroke of the two sets of irradiation elements is adjustable, and the irradiation range can partially overlap when the distance is closest. Thus, this device can not only fully irradiate the printed matter to cure the ink, but also adjust the stroke of the irradiation elements according to the size of the printed matter to avoid unnecessary energy consumption.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0027] like Figures 1-4 As shown, a printing ink curing device includes a feeding component 1 that can laterally convey printed materials to be cured in the device, a curing component 2 that can meet the curing needs of printed materials of different sizes without excessive energy consumption, and a driving component 3 that can make the curing component 2 operate as needed.

[0028] In this embodiment: the feeding assembly 1 includes a frame 101, a feeding frame 102 is fixedly connected above the frame 101, and a rotating roller 103 is movably connected to both ends of the feeding frame 102. A conveyor belt 104 is arranged between the rotating rollers 103, and a first motor 105 is fixedly connected to the rear of one of the rotating rollers 103.

[0029] The feeding frame 102 is rotatably connected to the rotating roller 103; the frame 101 provides the installation position and support for the feeding frame 102, the rotating roller 103 installs the conveyor belt 104 inside the feeding frame 102, and the rotating roller 103 connected to the first motor 105 transmits the rotation of the output end of the first motor 105 to the conveyor belt 104.

[0030] In this embodiment: the curing component 2 includes an irradiation element that can generate high-intensity ultraviolet light and irradiate the printed matter, a swinging element that can drive the irradiation element to fully cover the printed matter, and a loading element that can limit the movable range of the swinging element. The loading element includes a receiving box 201 fixedly installed above the feeding component 1, and a carrier frame 202 fixedly installed inside the receiving box 201. The swinging element includes a movable frame 204 movably installed inside the carrier frame 202, a rack 205 fixedly connected to the movable frame 204, a bearing seat 206 fixedly installed on both sides of the carrier frame 202, a rotating shaft 207 movably connected between the bearing seats 206, and a gear 208 fixedly connected to the outer side of the rotating shaft 207. The loading element also includes a limiting rod 203 fixedly installed inside both sides of the carrier frame 202. The irradiation element includes a lamp holder 209 fixedly connected between the movable frames 204 of the same height, and a UV lamp 210 fixedly installed inside the lamp holder 209.

[0031] The rack 205 is meshed with the gear 208, the carrier 202 and the limiting rod 203 are slidably connected to the movable frame 204, and the bearing 206 is rotatably connected to the rotating shaft 207.

[0032] The housing 201 provides an installation position for the carrier 202. The carrier 202 and the limiting rod 203 together restrict the movable range of the moving frame 204, so that the moving frame 204 can only move longitudinally relative to the carrier 202. The moved moving frame 204 changes the position of the lamp holder 209 for the UV lamp 210 in this device. The shaft 207 with the gear 208 is installed in the carrier 202 through the bearing 206. Through the meshing of the rack 205 and the gear 208, when the drive assembly 3 drives the higher moving frame 204 to move longitudinally, the lower moving frame 204 can move synchronously in the opposite direction with the higher moving frame 204.

[0033] In this embodiment: the drive assembly 3 includes a second motor 301 fixedly installed above the housing 201, a reducer 302 is provided behind the second motor 301, a support 303 is provided behind the reducer 302, a lead screw 304 is movably connected between the supports 303, a first coupling 305 is fixedly connected between the output end of the second motor 301 and the input end of the reducer 302, a second coupling 306 is fixedly connected between the output end of the reducer 302 and the lead screw 304, a slider 307 is provided between the housing 201 and the lead screw 304, and a T-shaped frame 308 is fixedly connected above the higher movable frame 204;

[0034] The receiving box 201 is slidably connected to the slider 307, the support 303 is rotatably connected to the lead screw 304, and the lead screw 304 is threadedly connected to the slider 307.

[0035] The rotation of the output end of the second motor 301 is transmitted to the lead screw 304 through the first coupling 305, the reducer 302, and the second coupling 306, so that the lead screw 304 can rotate relative to the support 303. The reducer 302 can increase the transmission torque of the lead screw 304, improve the motion accuracy and load capacity of the lead screw 304. After rotation, the lead screw 304 can drive the slider 307 to move longitudinally relative to the housing 201. The movement of the slider 307 is transmitted to the movable frame 204 connected to it through the T-shaped frame 308.

[0036] Working principle: When this device is installed and used for the curing of printing ink, after the second motor 301 starts working, the rotation of its output end will be transmitted to the lead screw 304 through the first coupling 305, reducer 302, and second coupling 306 after speed reduction and torque increase. This allows the lead screw 304 to drive the higher moving frame 204 to move longitudinally through the slider 307 and T-shaped frame 308. Under the action of the rack 205 and gear 208, the lower moving frame 204 will move synchronously in the opposite direction.

[0037] Therefore, by controlling the rotation angle of the second motor 301 in a single direction and the frequency of forward and reverse rotation, the two sets of UV lamps 210 with different heights can swing in the housing 201 with adjustable stroke and a minimum distance close to the diameter of the rotating shaft 207. When the distance is the smallest, the irradiation range of the two sets of UV lamps 210 can partially overlap.

[0038] Based on this, when the printed matter is placed on the conveyor belt 104 in a longitudinally centered manner, and the first motor 105 operates to make the conveyor belt 104 transport the printed matter laterally at a certain speed, the operating frequency of the second motor 301 can be adjusted according to the size of the printed matter. This allows the UV lamp 210 to determine the swing stroke based on the front and rear edges of the printed matter when the printed matter moves laterally, thereby achieving full irradiation of the printed matter by the device while avoiding unnecessary energy consumption.

[0039] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
