Description

Technical Field

[0001] The invention relates to the field of printing, and in particular to an intelligent multifunctional oil painting printing device and a use method thereof. Background Art

[0002] UV inkjet printing is a printing technology that uses ultraviolet (UV) light-curing ink. This technology is widely used in advertising, interior decoration, exhibition display, personalized gift making and other fields.

[0003] When an existing UV inkjet printer is used to inkjet print on an oil canvas, in order to improve work efficiency, workers usually set up continuous inkjet printing through a computer, that is, to continuously print multiple patterns on a longer oil canvas. However, since the inkjet printing widths of various patterns are different, workers need to set the movement range of the sprayer according to the range of the inkjet printing pattern each time, that is, they need to reprogram the movement program to control the movement range of the sprayer according to the inkjet printing width of the pattern, which is complicated to operate. Therefore, in the prior art, the sprayer is usually directly allowed to move through the entire range of the canvas width to adapt to different inkjet printing widths; but regardless of the inkjet printing width of the pattern, the sprayer is directly allowed to move through the entire range, which affects the inkjet printing efficiency of the pattern when printing a pattern with a small inkjet printing width.

[0004] In addition, due to the different widths of patterns, the width of the reserved blank space will also be different, and these excess blank spaces will need to be manually trimmed later, resulting in a large amount of manual labor.

[0005] At the same time, although the existing UV inkjet printers can print directly on a variety of materials, such as canvas, aluminum plates and wood boards, in actual operation, different devices are required for printing cloth and printing flat materials such as aluminum plates and wood boards; these two devices are not compatible, which brings many inconveniences and limitations.

[0008] More preferably, it further comprises a first clamping block and a second clamping block; the upper side of each sliding block is connected to the first clamping block via a control member; and the opposite sides of the two first clamping blocks are connected to the second clamping blocks via a control member.

[0009] More preferably, it also includes a wedge block and a spring; each sliding block is provided with a first slide groove; each first clamping block is provided with a second slide groove, and the first slide groove and the corresponding second slide groove are connected to each other; each second fixed block slides in the corresponding first slide groove and second slide groove; a plurality of wedge blocks are slidably connected to the lower side of each second fixed block; a plurality of springs are fixedly connected between each wedge block and the second fixed block; a plurality of first fixed grooves are provided on the side wall of each first slide groove; a plurality of second fixed grooves are provided on the side wall of each second slide groove.

[0010] More preferably, a plurality of electrically rotating rollers are arranged on the lower side of the first fixed block.

[0011] More preferably, it further comprises an electric roller; the lower side of each sliding block is rotatably connected to the electric roller.

[0012] More preferably, it further comprises an ultraviolet curing lamp; the lower left part and the lower right part of the sprayer are both fixedly connected with an ultraviolet curing lamp for quickly curing the printing ink.

[0013] More preferably, a smoothing roller is further included; the left and right sides of the sprayer are rotatably connected with the smoothing roller.

[0014] More preferably, an extrusion block is further included; the extrusion blocks are fixedly connected to the left and right sides of the sprayer; and the extrusion blocks are closer to the pressure sensor than the smoothing roller.

[0015] More preferably, the extrusion block is made of sponge material.

[0016] A method for using an intelligent multifunctional oil painting printing device, the specific steps are as follows:

[0017] Step 1: Pull out the canvas and pass it through the gap between the first fixed block and the upper surface of the workbench and the upper side of the tension roller; then use the transmission system to drive the canvas to move forward and feed; then the sprayer will move left and right according to the set program to spray print on the canvas;

[0018] Step 2: When printing, the canvas is cut longitudinally by the first cutter to cut the excess white space on the canvas; the canvas is cut transversely by the second cutter; the first cutter and the second cutter are used to cut the painting after printing; the subsequent winding roller will roll up the remaining white space scraps; the workers only need to collect the cut paintings;

[0020] The beneficial effects of the present invention are as follows: the present invention realizes limiting the left and right moving range of the sprayer by means of a sliding block, so that when the sprayer moves left and right, it contacts the pressure sensor on the sliding block, and after being squeezed, the pressure sensor sends a signal to the control system on the workbench, thereby controlling the sprayer to move to another direction, and then limiting the left and right moving range of the sprayer by means of the sliding block, so that the sprayer can change the left and right moving range according to the width of the spray printing, thereby ensuring the spraying efficiency of the pattern, and there is no need to manually modify the program frequently to change the moving range of the sprayer;

[0021] The canvas is supported upward by the tensioning roller, so that there is a gap between the canvas and the upper surface of the workbench, which is convenient for the first cutter and the second cutter to cut the canvas longitudinally and transversely. In this way, after the spray painting is completed, there is no need to manually cut the blank area, and only the cut canvas needs to be collected, which greatly improves the work efficiency. After the movement range of the sprayer is limited by the sliding block, the second cutter will not cut the entire canvas transversely. Therefore, when the excess scraps are transmitted out, the workers can wrap the excess scraps on the winding roller, and then use the winding roller to wind up the excess scraps for recycling.

[0022] When spraying a flat plate, the worker adjusts the position of the sliding block according to the width of the flat plate, so that a placement area for the flat plate is formed between the two L-shaped first clamping blocks; then the worker pulls up the second fixing block to release the fixation of the second fixing block to the first clamping block; then the worker puts the flat plate into the placement area, and then clamps and corrects the flat plate through the first clamping block and the second clamping block; then the control part can drive the first clamping block to move back and forth, and spray prints on the flat plate through the sprayer; this method enables the spray printing equipment to spray print on different materials; greatly improves the compatibility and functionality of the equipment, and solves the problem that different equipment needs to be used when the existing equipment cannot spray print on different materials, which brings many inconveniences and limitations.

[0037] It also includes a wedge block 110 and a spring 111; each sliding block 102 is provided with a first slide groove 10201; each first clamping block 103 is provided with a second slide groove 10301, and the first slide groove 10201 and the corresponding second slide groove 10301 are connected to each other; each second fixed block 105 slides in the corresponding first slide groove 10201 and the second slide groove 10301; a plurality of wedge blocks 110 are slidably connected to the lower side of each second fixed block 105; a plurality of two springs 111 are fixedly connected between each wedge block 110 and the second fixed block 105; a plurality of first fixed grooves 10202 are provided on the side wall of each first slide groove 10201; a plurality of second fixed grooves 10302 are provided on the side wall of each second slide groove 10301, and each wedge block 110 is snapped into the corresponding first fixed groove 10202 in the initial state.

[0038] A plurality of electrically rotating rollers are disposed on the lower side of the first fixing block 101 .

[0039] It also includes an electric roller 107 ; the lower side of each sliding block 102 is rotatably connected to the electric roller 107 .

[0040] The control component is composed of a slide rail and an electric slide block, and is used to drive the corresponding sliding block 102, the first clamping block 103 and the second clamping block 104 to move.

[0041] When the existing UV inkjet printer is inkjet printing on the canvas 555, the worker needs to set the moving range of the sprayer 3 according to the range of the inkjet pattern each time, that is, the moving program needs to be re-compiled to control the moving range of the sprayer 3 according to the inkjet printing width of the pattern. The operation is complicated, so in the prior art, the sprayer 3 is usually directly allowed to move the entire range of the width of the canvas 555 to adapt to different inkjet printing widths; but regardless of the inkjet printing width of the pattern, the sprayer 3 is directly allowed to move the entire range, which affects the inkjet printing efficiency of the pattern when the inkjet printing width is small; in addition, due to the different pattern widths, the reserved blank widths will also be different, and these excess blanks will need to be manually cut later, resulting in a large amount of manual labor.

[0042] In order to solve the above problems, the present invention proposes the following method: before starting work, the worker will first pull out the oil canvas 555, and make the end of the oil canvas 555 pass through the gap between the first fixed block 101 and the upper surface of the workbench 2, and adjust the operating program through the control system on the workbench 2, then start the equipment, and then drive the oil canvas 555 through the gap between the first fixed block 101 and the upper surface of the workbench 2 to move forward for feeding through the transmission system. At this time, the oil canvas 555 is compacted and limited by a number of electric rotating rollers on the lower side of the first fixed block 101 to prevent the oil canvas 555 from deflecting, and at the same time assist the oil canvas 555 to move forward for feeding; at the same time, the sprayer 3 will move left and right according to the set program to spray-print the oil canvas 555; before the sprayer 3 moves left and right for spray-printing, the two sliding blocks 102 are driven to move through the control component, so that the two sliding blocks 102 are respectively moved to the left and right sides of the oil canvas 555 Leave a blank position; then start the sprayer 3 to move for inkjet printing. At this time, the sprayer 3 will contact the pressure sensor 108 on the sliding block 102 during the process of moving to the left and to the right. After being squeezed, the pressure sensor 108 will send a signal to the control system on the workbench 2, thereby controlling the sprayer 3 to move to the other side, and then the sliding block 102 is used to limit the left and right movement range of the sprayer 3, so that the sprayer 3 can change the left and right movement range according to the width of the inkjet printing, thereby ensuring the inkjet printing efficiency of the pattern, and there is no need to manually modify the program frequently to change the movement range of the sprayer 3; and in the process of the sprayer 3 performing inkjet printing, the electric roller 107 will rotate according to the conveying rate of the transmission system. At this time, the oil canvas 555 located between the two first fixed blocks 101 is compacted by the electric roller 107 to prevent the oil canvas 555 from shifting, thereby ensuring the inkjet printing effect, and at the same time assisting the oil canvas 555 to move forward for feeding.

[0043] When the worker pulls out the canvas 555 and makes the canvas 555 pass through the gap between the first fixed block 101 and the upper surface of the workbench 2, the canvas 555 will be supported on the upper side of the tensioning roller 109. At this time, the contact position between the canvas 555 and the tensioning roller 109 will bulge upward, so that there is a gap between the canvas 555 and the upper surface of the workbench 2. At the same time, the canvas 555 is restricted by the electric rotating roller and the electric rotating roller 107 on the first fixed block 101, so that the canvas 555 is in a tensioned state. Then, before the sprayer 3 moves left and right to spray the canvas 555, the second cutter 201 located in the square groove 3001 is controlled to rotate out, and the rotation point of the second cutter 201 and the sprayer 3 is located at the tensioning position. The second cutter 201 is above and behind the roller 109, so that when the second cutter 201 rotates out of the square groove 3001, the second cutter 201 will cut into the upward protrusion of the canvas 555, so that when the sprayer 3 moves left and right to start spraying the canvas 555, the sprayer 3 performs a horizontal cut on the starting position of the canvas 555, and the cutting range is limited by the sliding block 102, so that the cutting range is the width of the spraying pattern. After the sprayer 3 moves back and forth once, the second cutter 201 rotates and retracts into the square groove 3001 to avoid cutting the canvas 555 during normal spraying; then as the sprayer 3 performs the spraying work, the transmission system, the electric rotating roller on the first fixed block 101 and the electric rotating roller 107 drive the canvas 5 Before the canvas 555 moves, the first cutter 106 extends downward from the second fixed block 105, and the first cutter 106 is also located above and behind the tensioning roller 109, so that when the canvas 555 moves for spraying, the canvas 555 is cut longitudinally by the first cutter 106, and the first cutter 106 is flush with the sliding block 102 on the side facing the spraying area of ​​the canvas 555, so that the blank area of ​​the canvas 555 is cut by the first cutter 106 and the second cutter 201. When the canvas 555 after spraying and printing moves to the front side of the sliding block 102, the second cutter 201 is controlled to rotate out of the square groove 3001, and then the sprayed pattern is cut by the reciprocating movement of the sprayer 3. At this time, the sprayer 3 does not perform spraying work, but only performs moving and cutting operations. In this way, after the spraying is completed, there is no need to manually cut the blank area. The worker only needs to collect the cut oil painting, which greatly improves the work efficiency; and after the moving range of the sprayer 3 is limited by the sliding block 102, the second cutter 201 will not cut the entire oil painting canvas 555 horizontally. Therefore, when the excess scraps are transmitted out, the worker can wind the excess scraps on the winding roller 4, and then use the winding roller 4 to wind up the excess scraps for recycling. It should be noted here that the winding roller 4 rotates according to the conveying rate of the transmission system; this method greatly improves the functionality of the equipment.

[0044] Although the existing UV inkjet printer can directly print on a variety of materials, such as canvas 555, aluminum plate and wood board, in actual operation, different equipment is required for printing canvas 555 and printing aluminum plate, wood board and other flat materials 666; these two types of equipment are not compatible, which brings many inconveniences and limitations; Figure 3 , Figure 4 and Figure 7 As shown: in the initial state, the second fixing block 105 is located in the first slide groove 10201 and the second slide groove 10301 at the same time, at this time the spring 111 is in the extended state, and the wedge blocks 110 are all stuck in the corresponding first fixing groove 10202 to fix the first clamping block 103; when it is necessary to spray-print on a flat plate 666 material such as an aluminum plate or a wooden plate, the worker first drives the sprayer 3 to move upward to the top of the first clamping block 103 through the control system of the workbench 2 to avoid collision between the first clamping block 103 and the sprayer 3 during subsequent adjustments; then the worker adjusts the position of the sliding block 102 according to the width of the flat plate 666, so that a placement area for the flat plate 666 is formed between the two L-shaped first clamping blocks 103; and then The worker then pulls up the second fixing block 105. At this time, the wedge block 110 is pressed and moves into the second fixing block 105. The spring 111 is compressed and contracts, and the wedge block 110 withdraws from the first fixing groove 10202. Then the second fixing block 105 moves upward in the first fixing groove 10202. When the wedge block 110 reaches the second fixing groove 10302, the spring 111 stretches and resets, and the wedge block 110 is stuck in the second fixing groove 10302. At this time, the second fixing block 105 withdraws from the first slide groove 10201 and is only located in the second slide groove 10301. Therefore, the second fixing block 105 releases the fixation of the first clamping block 103. At the same time, the second fixing block 105 protrudes upward and separates from the first clamping block 103. Then Figure 7As shown: the control member will drive the first clamping block 103 to move forward, and then push the placement area of ​​the flat plate 666 formed between the two first clamping blocks 103 to the front of the workbench 2, so that the worker can place the flat plate 666; then the worker puts the flat plate 666 between the two first clamping blocks 103, and then the control member will drive the second clamping block 104 to move forward, and then push the flat plate 666 forward, so that the front side of the flat plate 666 contacts the second fixed block 105, and cooperate with the second fixed block 105 to clamp and correct the front and rear directions of the flat plate 666, at the same time, the control member will again drive the sliding block 102 to move to the opposite side, and then clamp and correct the left and right directions of the flat plate 666 through the two first clamping blocks 103, and then through this method, it can adapt to flat plates 666 of different sizes, increasing the applicability of the present invention; the flat plate 666 After the clamping correction is completed, the running program is started, and then the sprayer 3 will move downward to a suitable spraying position on the upper side of the flat plate 666; then the control component gradually drives the first clamping block 103 to move backward, and the sprayer 3 moves left and right, and then the upper surface of the flat plate 666 is spray-printed; after the spray-printing is completed, the control component drives the spray-printed flat plate 666 to move forward and back to the initial position, so that the worker can take out the flat plate 666, and then put a new flat plate 666 to continue the spray-printing; and then through this method, the spray-printing equipment can spray-print different materials and adapt to flat plates 666 of different sizes; it greatly improves the compatibility and functionality of the equipment, and solves the problem that the existing equipment cannot spray-print different materials and needs to use different equipment, which brings many inconveniences and limitations. Example 2

[0045] On the basis of Example 1, Figure 8 and Fig. 9 As shown, an ultraviolet curing lamp 202 is also included; the ultraviolet curing lamp 202 is fixedly connected to the lower left part and the lower right part of the sprayer 3.

[0046] It also includes a smoothing roller 204; the left and right sides of the sprayer 3 are both rotatably connected to the smoothing roller 204.

[0047] It also includes an extrusion block 203 ; the extrusion block 203 is fixedly connected to the left and right sides of the sprayer 3 ; the extrusion block 203 is closer to the pressure sensor 108 than the smoothing roller 204 .

[0048] The squeezing block 203 is made of sponge material.

[0049] A method for using an intelligent multifunctional oil painting printing device, the specific steps are as follows:

[0050] Step 1: Pull out the canvas 555 and pass it through the gap between the first fixed block 101 and the upper surface of the workbench 2 and the upper side of the tension roller 109; then use the transmission system to drive the canvas 555 to move forward for feeding; then the sprayer 3 will move left and right according to the set program to spray print on the canvas 555;

[0051] Step 2: During the printing process, the first cutter 106 is used to cut the canvas 555 longitudinally and the excess blank space of the canvas 555 is cut; the second cutter 201 is used to cut the canvas 555 transversely; and the first cutter 106 and the second cutter 201 are used to cut the painting after the printing process is completed; at the same time, the subsequent winding roller 4 will wind up the remaining blank scraps; the worker only needs to collect the cut paintings;

[0052] Step three: When spraying the flat plate 666, the worker adjusts the position of the sliding block 102 according to the width of the flat plate 666, so that a placement area for the flat plate 666 is formed between the two L-shaped first clamping blocks 103; then the worker pulls up the second fixing block 105 to release the fixation of the second fixing block 105 to the first clamping block 103; then the worker places the flat plate 666 into the placement area, and then clamps and corrects the flat plate 666 through the first clamping block 103 and the second clamping block 104; then the control component can drive the first clamping block 103 to move forward and backward, and spray print on the flat plate 666 through the sprayer 3.

[0053] During the process of inkjet printing by the sprayer 3, the ink in the spraying area is cured by ultraviolet light through the ultraviolet curing lamp 202, so as to facilitate the rapid curing of the ink, improve production efficiency, and ensure the quality of inkjet printing; when the sprayer 3 moves left and right, the smoothing rollers 204 on the left and right sides of the sprayer 3 will compact and smooth the oil canvas 555 in the spraying area to ensure the inkjet printing effect; and when the sprayer 3 contacts the pressure sensor 108, the sponge material extrusion block 203 will first contact the pressure sensor 108, reduce the collision extrusion force and trigger the pressure sensor 108 at the same time, thereby preventing the sprayer 3 from directly colliding with the pressure sensor 108 and improving the service life of the sprayer 3.
