Description

Technical Field

[0001] The present invention relates to the technical field of fabric printing, and particularly to a device and method for manufacturing a three-dimensional letter placket. Background Art

[0002] As a method for printing on fabrics, there are plate printing and plate-free printing. Plate printing, also known as screen printing, is a printing method using a printing plate with a screen. Through holes (openings) corresponding to a predetermined pattern are formed in the screen, ink is supplied to the screen, and a squeegee presses the ink and moves (slides) on the printing plate, so that the ink passes through the through holes and the predetermined pattern is printed on the fabric. Through one movement of the squeegee, plate printing can print a large area of the fabric corresponding to the size of the through holes in the printing plate in the same color, so it is suitable for printing the background of monochromatic patterns and can perform high-speed printing.

[0003] Now, when using colloidal printing to print three-dimensional letters on placket fabrics, it is necessary to use a laser to first engrave the outer contour of the pattern to be printed on the placket fabric, so as to facilitate subsequent brushing of the colloid to form the required three-dimensional letter pattern. However, when the laser engraves the placket fabric, it uses the principle of high-temperature burning, so thick smoke will be generated during the engraving process, and the smoke is accompanied by burning impurities of the fabric. These impurities are easily attached to the laser head to block the light source. Summary of the Invention

[0004] The purpose of the present invention is mainly to solve the problems that thick smoke will be generated during the process of using a laser to engrave the outer contour of the pattern on the placket fabric, and the smoke is accompanied by burning impurities of the fabric, and these impurities are easily attached to the laser head to block the light source.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: A device and method for manufacturing a three-dimensional letter placket, including a protective cover, a workbench, and a laser head. A driving mechanism is arranged on the workbench, and a diversion device and a protection device are arranged on the driving mechanism. The diversion device includes a fixed block and an installation opening for fixing the protection device. A buffer cavity and a plurality of flow channels for air flow are opened inside the fixed block. The protection device includes an installation column and a diversion cover. The laser head is fixed at the bottom of the installation column. An installation groove, an inner cavity, and a plurality of side holes for air flow are opened inside the installation column. A third motor is fixed inside the inner cavity, and a plurality of blades for sucking air are fixed at the output end of the third motor.

[0006] Preferably, the driving mechanism includes a movable arm. Sliding grooves are formed at the top of the workbench near both side edges and at the top of the movable arm. Lead screws are rotatably connected inside both sliding grooves. Both ends of the movable arm are arranged inside the sliding grooves on the workbench and are connected to the lead screws. One end of the lead screw inside one of the sliding grooves is fixed with a first motor, and one end of the lead screw on the movable arm is fixed with a second motor. A sliding block is slidably connected inside the sliding groove on the movable arm.

[0007] Preferably, multiple flow channels are correspondingly distributed on the inner top surface and bottom surface of the buffer cavity. Multiple flow channels on the inner top surface of the buffer cavity are all communicated to the inside of the installation opening. Multiple flow channels at the bottom of the buffer cavity correspondingly penetrate through to the bottom of the fixed block. A retaining ring is fixed between the inner walls of the installation opening.

[0008] Preferably, the installation groove and multiple side holes are all communicated with the inner cavity. The installation groove penetrates through to the top of the installation column. A filter element is arranged inside the installation groove. Multiple support rods are fixed on the outer surface of the third motor. One end of each of the multiple support rods is correspondingly fixed on the inner wall of the inner cavity.

[0009] Preferably, the top of the filter element is in contact with the bottom of the retaining ring.

[0010] Preferably, multiple side holes all penetrate through to the top and bottom of the installation column. The flow guide cover is fixed at the bottom of the installation column and extends obliquely towards the laser head side.

[0011] Preferably, a backing plate and two conveying rollers are arranged inside the workbench. Two limiting plates are fixed on the inner bottom surface of the protective cover. A control panel is fixed on one side of the protective cover.

[0012] The present invention also provides a method for manufacturing a three-dimensional lettered bottom placket, including the following steps:

[0013] Step S1: Place the bottom placket fabric on the conveying rollers so that the bottom placket fabric can be conveyed. During the conveying process, the bottom placket fabric is processed by the laser head.

[0014] Step S2: When processing the bottom placket fabric with the laser head, fix the laser head at the bottom of the installation column. During movement, by the rotation of the first motor and the second motor, drive the lead screw to move, thereby driving the movable arm and the sliding block to slide, so as to drive the laser head to move, so that the laser head can move horizontally to process the bottom placket fabric.

[0015] Step S3: During the machining of the laser head, the third motor drives the blade to rotate, causing air to flow into the interior of the buffer chamber through the flow channel at the bottom of the fixed block, and then flow into the mounting opening. After being filtered by the filter element, the air flows out through the inner cavity from multiple side holes, so that the air with impurities generated during machining can be adsorbed and purified.

[0016] Step S4: The purified air flow blows towards the laser head under the guidance of the flow deflector after passing through the side holes, hitting the outer surface of the laser head to form a reverse air flow, thereby preventing pollutants from adhering to the laser head.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows.

[0018] 1. In the present invention, when the laser head is working, the gas with pollutants flows into the interior through the flow channel at the bottom of the fixed block. By driving the blade to rotate with the third motor, the air flows towards the mounting opening. After being filtered by the filter element, the air flows out through the inner cavity from multiple side holes. The air flow blows towards the laser head under the guidance of the flow deflector after passing through the side holes, hitting the outer surface of the laser head to form a reverse air flow.

[0019] 2. In the present invention, when moving the laser head, by rotating the first motor and the second motor, the lead screw is driven to move, thereby driving the movable arm and the sliding block to slide, driving the laser head to move. At the same time, the movable arm is arranged inside two sliding grooves, so that the laser head can be moved in a plane in cooperation with the sliding block.

[0020] 3. In the present invention, the protection device is arranged inside the flow guiding device, and the flow channels at the bottom of the fixed block are arranged around, so that when the air flow flowing out from the side holes hits the laser head to form a reverse air flow, the polluted air blown towards the surroundings can be better absorbed. At the same time, a retaining ring is arranged inside the mounting opening to prevent the filter element from shaking. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the lead screw 32 inside one of the sliding grooves 31 is fixed with a first motor 33, one end of the lead screw 32 on the movable arm 36 is fixed with a second motor 34, and a sliding block 35 is slidably connected inside the sliding groove 31 on the movable arm 36.

[0031] The effect achieved by the entire Embodiment 2 is that when the laser head 10 is moved, the rotation of the first motor 33 and the second motor 34 drives the lead screw 32 to move, thereby driving the movable arm 36 and the sliding block 35 to slide, driving the laser head 10 to move. At the same time, the movable arm 36 is arranged inside the two sliding grooves 31, so that the laser head 10 can be moved in a plane in cooperation with the sliding block 35.

The plurality of flow channels 43 located at the bottom of the buffer chamber 41 all correspondingly penetrate to the bottom of the fixing block 45. A retaining ring 44 is fixed between the inner walls of the mounting port 42. The mounting groove 52 and the plurality of side holes 54 are all communicated with the inner cavity 53.

A control panel 8 is fixed on one side of the protective cover 1.

[0033] The overall effect achieved by the entire Embodiment 3 is that the protection device 5 is arranged inside the diversion device 4, and the flow channels 43 at the bottom of the fixing block 45 are arranged around, so that when the air flow flowing out from the side holes 54 hits the laser head 10 to form a reverse air flow, the polluted air blown to the surroundings can be better absorbed. At the same time, a retaining ring 44 is arranged inside the mounting port 42 to prevent the filter element 56 from shaking. The flow guide cover 55 is fixed at the bottom of the mounting post 51 and extends obliquely towards the laser head 10, so that the air flow can directly blow towards the laser head 10. A backing plate 7 and two conveying rollers 6 are arranged inside the workbench 2 to facilitate the conveying of the fabric.

[0034] The present invention also provides a method for manufacturing a three-dimensional letter bottom placket, including the following steps:

[0037] Step S3: When the laser head 10 is being processed, the third motor 57 drives the blade 59 to rotate, causing air to flow into the interior of the buffer chamber 41 through the flow channel 43 at the bottom of the fixed block 45. Then, it flows into the mounting opening 42 and, after being filtered by the filter element 56, flows out through the plurality of side holes 54 from the inner cavity 53, enabling the adsorption and purification of the air with attached impurities generated during processing. When installing the filter element 56, by arranging the retaining ring 44 in the mounting opening 42, the filter element 56 can be pressed, preventing it from shaking.

[0038] Step S4: The purified air flow blows towards the laser head 10 under the guidance of the flow deflector 55 after passing through the side holes 54, hitting the outer surface of the laser head 10 to form a reverse air flow, thereby preventing contaminants from adhering to the laser head 10.
