Description

Technical Field

[0001] The present application relates to the technical field of mask production, and particularly to a mask production device for engraving patterns. Background Art

[0002] A mask is a personal protective barrier product, which is worn over the nose and mouth and is used to filter the air entering and leaving the nose and mouth, so as to block harmful gases, dust, and droplets from entering and leaving the wearer's nose and mouth, and is mostly made of gauze and the like.

[0003] During the mask production process, patterns are often engraved on the surface of the mask by hot pressing to improve the wearing aesthetics of the mask; in the prior art, a hot pressing roller is usually arranged above a conveyor belt to engrave patterns on the mask. A hot pressing die area with a certain shape protrudes on the peripheral wall of the hot pressing roller, and a gap for the mask to pass through is left between the peripheral wall of the hot pressing roller and the surface of the conveyor belt. When the mask passes through the gap between the hot pressing roller and the surface of the conveyor belt, the hot pressing roller is driven to roll by a driving member. During the rolling process of the hot pressing roller, the hot pressing die area of the hot pressing roller acts on the surface of the mask, so that patterns are hot pressed on the surface of the mask, greatly improving the overall aesthetics of the mask.

[0004] In the actual production requirements of masks, it is necessary to hot press masks with patterns of different shapes to improve the diversity of masks; however, the hot pressing die areas of such hot pressing rollers are integrally formed on the peripheral surface of the hot pressing roller, resulting in the need to replace different equipment or different hot pressing rollers when it is necessary to hot press masks with patterns of different shapes. In the method of replacing the hot pressing roller, it is necessary to disassemble the transmission connection between the hot pressing roller and the driving member to replace the new hot pressing roller. Frequent disassembly of the transmission connection between the hot pressing roller and the driving member easily causes the transmission connection to become loose, thereby reducing the rolling stability of the hot pressing roller. Therefore, further improvement is needed. Summary of the Invention

[0005] In order to adapt to the hot pressing operation of masks with patterns of different shapes, the present application provides a mask production device for engraving patterns.

[0006] The mask production device for engraving patterns provided by the present application adopts the following technical solutions:

[0007] A mask production device for imprinting patterns, comprising a conveyor belt and a hot pressing die disposed above the conveyor belt. The hot pressing die includes a hot pressing roller and a driving roller. The peripheral wall of the hot pressing roller is provided with a hot pressing die area for hot pressing on the mask to form a pattern. There are two driving rollers, and the hot pressing roller and the two driving rollers are coaxially arranged. The two driving rollers are respectively disposed at both ends of the hot pressing roller to clamp the hot pressing roller. A connecting member is provided between the hot pressing roller and the driving roller, and the hot pressing roller and the driving roller are detachably connected through the connecting member. The two driving rollers are respectively rotatably installed on both sides in the width direction of the conveyor belt, and the driving roller is provided with a driving member for driving the driving roller to rotate.

[0008] By adopting the above technical solution, through the arrangement of the hot pressing roller and the driving roller, when imprinting a pattern on the surface of the mask, the driving member drives the driving roller to rotate. The two driving rollers clamp the hot pressing roller and are connected by the connecting member, so that the driving roller can drive the hot pressing roller to rotate synchronously during the rotation process. The hot pressing die area of the hot pressing roller acts on the surface of the mask to form a pattern, improving the aesthetic degree of the mask after being manufactured. When it is necessary to imprint patterns of different shapes on the surface of the mask, the connecting member between the hot pressing roller and the driving roller is disassembled, and the hot pressing roller can be removed and replaced with a hot pressing roller with a different hot pressing die area to adapt to the hot pressing operation of masks with different patterns, improving the adaptability of the overall structure.

[0009] Optionally, a first connecting groove is opened on the end face of the hot pressing roller close to the driving roller, and a second connecting groove communicating with the first connecting groove is opened on the end face of the driving roller away from the hot pressing roller. The connecting member includes a connecting rod, and the connecting rod sequentially passes through the second connecting groove and the first connecting groove. The connecting rod is threadedly connected between the first connecting groove and the second connecting groove.

[0010] By adopting the above technical solution, through the arrangement of the connecting rod, when installing the hot pressing roller, the hot pressing roller is axially placed between the two driving rollers, and then the connecting rod is threadedly connected to the second connecting groove. The connecting rod is continuously rotated to force the connecting rod to enter the first connecting groove and be threadedly connected to the first connecting groove, so that the hot pressing roller and the driving roller form an integral body under the threaded connection of the connecting rod, improving the disassembly and assembly convenience of the hot pressing roller.

[0011] Optionally, the tightening direction of the connecting rod is set in the opposite direction to the rotation direction of the driving roller.

[0012] By adopting the above technical solution, the tightening direction of the connecting rod is set to be opposite to the rotation direction of the driving roller. When the driving member drives the driving roller to rotate to drive the hot pressing roller to engrave patterns on the mask, during the rotation of the driving roller, the connecting rod can be forced to be tightened more and more between the connecting rod and the driving roller, so that the connecting rod is tightened toward the side close to the first connecting groove, improving the screw connection stability between the hot pressing roller and the connecting rod, and reducing the possibility that the connecting rod disengages from the first connecting groove and the hot pressing roller disengages from the driving roller.

[0013] Optionally, a first air blowing channel is provided inside the hot pressing roller, and a plurality of air blowing holes communicating with the first air blowing channel are provided on the outer peripheral wall of the hot pressing roller. All the air blowing holes are located in the hot pressing die area and are arranged at intervals along the contour edge of the hot pressing die area; a second air blowing channel communicating with the first air blowing channel is provided on the end face of the connecting rod away from the hot pressing roller, and the second air blowing channel is connected with a blowing member for supplying air to the first air blowing channel.

[0014] By adopting the above technical solution, through the arrangement of the first air blowing channel, the air blowing holes and the second air blowing channel, when the hot pressing roller rotates to engrave patterns on the surface of the mask, air is blown into the air blowing holes through the first air blowing channel, and the air can blow the surface of the mask, so that the mask has a force to move away from the hot pressing roller, reducing the possibility that the surface of the mask adheres to the peripheral wall of the hot pressing roller and the mask winds around the hot pressing roller when the hot pressing roller rotates and presses on the surface of the mask, and improving the engraving stability of the overall structure.

[0015] Optionally, an installation frame is provided on the side wall of the conveyor belt. The blowing member includes a blowing pipe installed on the installation frame. One end of the blowing pipe penetrates through the second air blowing channel and extends to the first air blowing channel. The driving roller and the hot pressing roller can rotate relative to the blowing pipe; a plurality of air outlet holes communicating with the inside of the blowing pipe are provided on the outer peripheral wall of the blowing pipe. The air outlet holes face the rear end of the hot pressing roller close to the conveying direction of the conveyor belt, and the included angle between the air outlet direction of the air outlet holes and the surface of the conveyor belt is between 84-88 degrees. When the air blowing direction of the air blowing holes of the hot pressing roller rotates around the axis of the hot pressing roller to be parallel to the air outlet direction of the air outlet holes, the air outlet holes communicate with the air blowing holes.

[0016] By adopting the above technical solution, through the setting of the blowing pipe, the included angle between the air outlet direction of the air outlet hole and the surface of the conveyor belt is between 84° and 88°. When the hot pressing roller rotates to hot press the surface of the mask, the blowing holes that have not rotated to be parallel to the air outlet direction of the air outlet hole cannot blow out gas outward. Thus, when the hot pressing roller hot presses the mask, the possibility that the blowing of the gas interferes with the hot pressing operation of the hot pressing roller is reduced; the gas in the blowing pipe can only be blown out through the blowing holes that have rotated to be parallel to the air outlet direction of the air outlet hole, so that the gas always blows toward the side of the hot pressing roller close to the rear end in the conveying direction of the conveyor belt, to reduce the possibility that the mask winds around the circumferential wall of the hot pressing roller; on the other hand, the gas always blows toward the rear end of the mask conveying, and the mask at the conveying rear end has been hot pressed. The gas can make the hot pressed mask quickly take shape, thereby improving the hot pressing efficiency of the mask.

[0017] Optionally, the blowing pipe is rotatably installed on the mounting bracket, and an elastic member is provided between the blowing pipe and the mounting bracket. The elastic member normally keeps the included angle between the air outlet direction of the air outlet hole and the surface of the conveyor belt between 84° and 88°; a docking assembly is provided between the blowing pipe and the hot pressing roller. When the blowing hole rotates to communicate with the air outlet hole, the docking assembly forces the blowing pipe to dock with the hot pressing roller and forces the blowing pipe to rotate following the hot pressing roller. The blowing pipe is provided with a limiting block for the blowing pipe to disengage from the hot pressing roller.

[0018] By adopting the above technical solution, through the setting of the elastic member, the docking assembly and the limiting block, when the blowing hole rotates to communicate with the air outlet hole, at this time the blowing pipe docks with the hot pressing roller under the action of the docking assembly, so that the hot pressing roller can drive the blowing pipe to rotate, and the blowing pipe and the hot pressing roller rotate synchronously, thereby keeping the air outlet hole communicating with the blowing pipe, and further prolonging the communication time between the air outlet hole and the blowing hole, to improve the effect of the gas blowing the mask; when the air outlet direction of the next blowing hole rotates to be the same as the air outlet direction of the initial position of the air outlet hole, the blowing pipe is stopped by the limiting block, so that the docking effect of the blowing pipe with the hot pressing roller is released, and the blowing pipe can rotate to the initial position under the action of the elastic member to dock with the next blowing hole. Repeating like this, the blowing pipe can rotate reciprocally, greatly prolonging the communication time between the air outlet hole and each blowing hole, thereby improving the blowing effect of the blowing pipe on the mask and reducing the possibility that the mask adheres to the hot pressing roller and winds around the hot pressing roller.

[0019] Optionally, the docking assembly includes a first magnet and a second magnet. The first magnet is fixed on the circumferential wall of the blowing pipe, and a plurality of second magnets are provided and arranged in one-to-one correspondence with the blowing holes. When the blowing hole rotates to communicate with the air outlet hole, the first magnet is attracted to the second magnet corresponding to the blowing hole.

[0020] By adopting the above technical solution, through the arrangement of the first magnet and the second magnet, when the air blowing hole rotates to communicate with the air outlet hole, at this time the first magnet is attracted to the second magnet and there is magnetic force, and the air blowing pipe can rotate a certain angle following the hot pressing roller under the action of the magnetic force; after the air blowing pipe rotates a certain angle, the limiting block stops the air blowing pipe, at this time the hot pressing roller continues to rotate, so that the first magnet can be separated from the second magnet by overcoming the magnetic force, and the air blowing pipe rotates to the initial position under the action of the elastic member, and the first magnet is attracted to the second magnet of the next air blowing hole, and so on, realizing the reciprocating rotation function of the air blowing pipe.

[0021] Optionally, all the second magnets are arranged at intervals around the central axis of the hot pressing roller, and adjacent second magnets are arranged at intervals along the length direction of the hot pressing roller; a plurality of first magnets are arranged and all the first magnets are arranged at intervals along the length direction of the hot pressing roller, and all the second magnets are arranged in one-to-one correspondence with all the first magnets. When the air blowing hole rotates to communicate with the air outlet hole, the second magnet is attracted to the corresponding first magnet.

[0022] By adopting the above technical solution, through the first magnets arranged at intervals and the second magnets arranged at intervals, the spaces between adjacent first magnets and between adjacent second magnets are staggered from each other, so as to reduce the possibility of mutual magnetic interference between adjacent first magnets or adjacent second magnets, and improve the rotation stability of the air blowing pipe.

[0023] Optionally, the hot pressing roller includes a hot pressing core roller and a hot pressing sleeve roller sleeved on the hot pressing core roller. The first connecting groove is arranged on the hot pressing core roller, the hot pressing die area is arranged on the outer peripheral wall of the hot pressing sleeve roller, an installation member is arranged between the hot pressing core roller and the hot pressing sleeve roller, and the hot pressing core roller and the hot pressing sleeve roller are detachably connected through the installation member.

[0024] By adopting the above technical solution, through the arrangement of the hot pressing core roller and the hot pressing sleeve roller, when printing masks with different patterns, by disassembling the hot pressing core roller and replacing the hot pressing sleeve roller with different hot pressing die areas, it is possible to adapt to the printing operations of different patterns and reduce the production cost.

[0025] Optionally, the outer diameter of the driving roller is set to be the same as the outer diameter of the hot pressing sleeve roller. A plugging groove is formed on the outer peripheral wall of the hot pressing core roller, and the two ends of the plugging groove penetrate through the two end faces of the hot pressing core roller respectively. The installation member includes a plugging strip and a blocking block. The plugging strip is fixed on the inner peripheral wall of the hot pressing sleeve roller, the plugging strip is slidably inserted into the plugging groove, and the blocking block is fixed at one end of the plugging groove. When one end of the plugging strip abuts against the blocking block, the two ends of the hot pressing core roller and the two ends of the hot pressing sleeve roller are kept flush.

[0026] By adopting the above technical solution, through the arrangement of the insertion slot and the insertion strip, when installing the hot pressing sleeve roller, one end of the hot pressing sleeve roller is aligned with one end of the hot pressing core roller away from the blocking block, and after the insertion strip is aligned with the insertion slot, it is pushed, so that the hot pressing sleeve roller can be sleeved on the outer peripheral wall of the hot pressing core roller. When the insertion strip of the hot pressing sleeve roller slides and abuts against the blocking block, the two ends of the hot pressing core roller and the two ends of the hot pressing sleeve roller are kept flush, completing the rapid installation between the hot pressing core roller and the hot pressing sleeve roller; then the hot pressing core roller and the hot pressing sleeve roller are moved between the two driving rollers, and the driving roller is fixedly connected with the hot pressing core roller through the connecting rod. The side wall of the driving roller can limit the end face of the hot pressing sleeve roller, so that the hot pressing core roller and the hot pressing sleeve roller form an integral body.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Through the arrangement of the hot pressing roller and the driving roller, when engraving patterns on the surface of the mask, the driving roller is driven to rotate by the driving member. The two driving rollers clamp the hot pressing roller and are connected by the connecting member, so that the driving roller can drive the hot pressing roller to rotate synchronously during the rotation process. The hot pressing die area of the hot pressing roller acts on the surface of the mask to form patterns, improving the aesthetics of the mask after being made; when it is necessary to engrave patterns of different shapes on the surface of the mask, the connecting member between the hot pressing roller and the driving roller is disassembled, and the hot pressing roller can be removed and replaced with a hot pressing roller with a different hot pressing die area to adapt to the hot pressing operation of masks with different patterns, improving the adaptability of the overall structure;

[0029] 2. Through the arrangement of the elastic member, the docking assembly and the limiting block, when the air blowing hole rotates to communicate with the air outlet hole, at this time, the air blowing pipe is docked with the hot pressing roller under the action of the docking assembly, so that the hot pressing roller can drive the air blowing pipe to rotate, and the air blowing pipe rotates synchronously with the hot pressing roller, so that the air outlet hole remains communicated with the air blowing pipe, thereby prolonging the communication time between the air outlet hole and the air blowing hole, and improving the effect of blowing the mask with gas; when the air outlet direction of the next air blowing hole rotates to be the same as the air outlet direction of the initial position of the air outlet hole, the limiting block stops the air blowing pipe, so that the air blowing pipe is separated from the docking effect of the hot pressing roller, and the air blowing pipe can rotate to the initial position under the action of the elastic member to dock with the next air blowing hole. Repeating like this, the air blowing pipe can rotate reciprocally, greatly prolonging the communication time between the air outlet hole and each air blowing hole, thereby improving the blowing effect of the air blowing pipe on the mask and reducing the possibility of the mask adhering to the hot pressing roller and winding around the hot pressing roller;

[0030] 3. Through the arrangement of the hot pressing core roller and the hot pressing sleeve roller, when engraving masks with different patterns, by disassembling the hot pressing core roller and replacing the hot pressing sleeve roller with a different hot pressing die area, it can adapt to the engraving operation of different patterns and reduce the manufacturing cost.

The hot pressing die 2 is installed between the two mounting seats 13, and the hot pressing die 2 is erected above the conveyor belt 1 through the two mounting seats 13. Each mounting seat 13 is installed with a sliding assembly 8 for driving the hot pressing die 2 to approach or move away from the conveyor belt 1.

[0044] Referring to Figure 1 , the sliding assembly 8 includes a sliding seat 81 and a sliding cylinder 82. The sliding seat 81 is slidably installed on the mounting seat 13, and both ends of the hot pressing die 2 are respectively installed on the two sliding seats 81; the cylinder body of the sliding cylinder 82 is fixedly installed on the side wall of the mounting seat 13 away from the conveyor belt 1, and the piston rod of the sliding cylinder 82 penetrates through the side wall of the mounting seat 13 and is fixedly installed on the sliding seat 81; designed in this way, by the extension or contraction of the piston rod of the sliding cylinder 82, the sliding seat 81 can be driven to approach or move away from the conveyor belt 1, and then the hot pressing die 2 can be pressed against or lifted from the mask on the conveyor belt 1 to hot press the surface of the mask to form a pattern.

[0048] Refer to Figure 2, a first connection groove 212 is formed on the end face of the hot pressing roller 21 close to the driving roller 22, and a second connection groove 221 is formed on the end face of the driving roller 22 away from the hot pressing roller 21. The second connection groove 221 communicates with the first connection groove 212. A connecting member 3 is installed between the first connection groove 212 and the second connection groove 221, and the hot pressing roller 21 is detachably connected between the two driving rollers 22 through the connecting member 3.

[0049] Referring to Figure 2 , in this embodiment, the connecting member 3 is set as a connecting rod 31.

And the tightening direction of the connecting rod 31 is set in the opposite direction to the rotation direction of the driving roller 22. With such a design, the two ends of the hot pressing roller 21 are detachably connected to the two driving rollers 22 through the connecting rod 31. When it is necessary to hot press masks with different shaped patterns, rotate the connecting rod 31 to force the connecting rod 31 to disengage from the first connection groove 212, and then the hot pressing roller 21 can be taken out and replaced with a hot pressing roller 21 with different shaped patterns, so that the overall structure can adapt to the hot pressing operation of masks with different shaped patterns and improve the adaptability of the overall structure.

[0050] Referring to Figure 2 , Figure 3 , in this embodiment, the hot pressing roller 21 includes a hot pressing core roller 215 and a hot pressing sleeve roller 216.

In this embodiment, the two ends of the plug-in groove 2151 extend along the length direction of the hot pressing core roller 215, and the two ends of the plug-in groove 2151 respectively penetrate through the two end faces of the hot pressing core roller 215. The installation member 7 includes a plug-in strip 71 and a blocking block 72. The plug-in strip 71 is fixedly installed on the inner peripheral wall of the hot pressing sleeve roller 216. The two ends of the plug-in strip 71 extend along the length direction of the hot pressing sleeve roller 216, and the plug-in strip 71 is slidably inserted into the plug-in groove 2151. The blocking block 72 is fixedly installed at one end of the plug-in groove 2151. When one end of the plug-in strip 71 abuts against the blocking block 72, the two ends of the hot pressing core roller 215 are flush with the two ends of the hot pressing sleeve roller 216.

[0052] With such a design, when installing the hot pressing sleeve roller 216, align one end of the hot pressing sleeve roller 216 with the end of the hot pressing core roller 215 away from the blocking block 72. At the same time, align the insertion strip 71 with the insertion groove 2151, and then push the hot pressing sleeve roller 216 so that the hot pressing sleeve roller 216 is sleeved on the outer peripheral wall of the hot pressing core roller 215. When the insertion strip 71 abuts against the blocking block 72, the two ends of the hot pressing core roller 215 and the two ends of the hot pressing sleeve roller 216 are kept flush, completing the preliminary installation and fixation between the hot pressing sleeve roller 216 and the hot pressing core roller 215. Then, place the hot pressing sleeve roller 216 and the hot pressing core roller 215 coaxially between the two driving rollers 22 and fix them by threaded connection with the connecting rod 31. The two driving rollers 22 can clamp the hot pressing sleeve roller 216 and the hot pressing core roller 215, so that the driving rollers 22, the hot pressing sleeve roller 216 and the hot pressing core roller 215 form an integral body.

[0053] Refer to Figure 1 , Figure 2 , Figure 3 , there is a first air blowing channel 213 opened inside the hot pressing core roller 215. The two ends of the first air blowing channel 213 are respectively communicated with the two first connecting grooves 212. There are a plurality of first air blowing holes on the outer peripheral wall of the hot pressing core roller 215 that are communicated with the first air blowing channel 213. A plurality of second air blowing holes penetrating through the hot pressing sleeve roller 216 are opened on the outer peripheral wall of the hot pressing sleeve roller 216.

The first air blowing holes and the second air blowing holes are combined to form complete air blowing holes 214. In this embodiment, all the air blowing holes 214 are located within the hot pressing die area 211 and all the air blowing holes 214 are arranged at intervals along the contour edge of the hot pressing die area 211.

By removing the fixing pin, the air blowing pipe 5 and the mounting frame 11 can be separated to facilitate the disassembly and assembly of the air blowing pipe 5.

[0055] Reference Figure 1 , Figure 2 In this embodiment, the air blowing pipe 5 is a tubular structure with one end open. Specifically, the end of the air blowing pipe 5 away from the driving motor is an open end. The open end of the air blowing pipe 5 is used to connect an air blowing hose (not shown in the figure). The air outlet end of the air blowing hose is fixedly connected to the open end of the air blowing pipe 5. The air inlet end of the air blowing hose is used to connect an air supply device (the air supply device can be an air pump. The air pump is a prior art means. Its structure is not elaborated too much here and is not shown in the figure). The outer peripheral wall of the air blowing pipe 5 is provided with a plurality of air outlet holes 51. All the air outlet holes 51 are arranged at intervals along the length direction of the air blowing pipe 5. Each air outlet hole 51 passes through the air blowing pipe 5 and is connected to the inside of the air blowing pipe 5.

[0056] Reference Figure 2 , Figure 3 , all the air outlet holes 51 are oriented toward the rear end of the hot pressing roller 21 close to the conveying direction of the conveyor belt 1, and the angle between the air outlet direction of the air outlet hole 51 and the surface of the conveyor belt 1 is between 84-88 degrees; specifically, the angle between the air outlet direction of the air outlet hole 51 and the surface of the conveyor belt 1 is set to 85 degrees; when the blowing direction of the blowing hole 214 of the hot pressing roller 21 rotates around the axial direction of the hot pressing roller 21 to be parallel to the air outlet direction of the air outlet hole 51, the air outlet hole 51 is connected to the corresponding blowing hole 214.

[0057] The implementation principle of Example 1 of the present application is as follows: when installing the hot pressing roller 21, align the plug-in strip 71 of the hot pressing sleeve roller 216 with the plug-in groove 2151 of the hot pressing core roller 215, and sleeve the hot pressing sleeve roller 216 on the outer peripheral wall of the hot pressing core roller 215 to form the hot pressing roller 21; then, place the hot pressing roller 21 between the two driving rollers 22 along its axial direction, and sequentially threadably connect the second connecting groove 221 and the first connecting groove 212 through the connecting rod 31, so that the hot pressing roller 21 and the two driving rollers 22 form a whole, so that when the driving motor drives the driving roller 22 to rotate, the hot pressing mold area 211 of the outer peripheral wall of the hot pressing sleeve roller 216 can roll and hot press the mask on the conveyor belt 1; when it is necessary to engrave patterns of different shapes on the mask, the driving roller 22 and the hot pressing roller 21 can be separated by disassembling the connecting rod 31 and replacing different hot pressing sleeve rollers 216, thereby improving the convenience of disassembly and assembly of the hot pressing roller 21, and thereby improving the adaptability of the overall structure;

[0058] After the hot pressing roller 21 is installed between the two driving rollers 22, the blowing pipe 5 is inserted through the driving roller 22 and the hot pressing roller 21, and the relative position between the blowing pipe 5 and the hot pressing roller 21 is fixed by the sliding seat 81, so that the air outlet 51 faces the rear end of the hot pressing roller 21 close to the conveying direction of the conveyor belt 1 and the angle between the air outlet direction of the air outlet 51 of the blowing pipe 5 and the surface of the conveyor belt 1 is maintained at 85 degrees; the hot pressing roller 21 rotates to heat and press the surface of the mask while the blowing pipe 5 is pressed Air supply, the gas in the blowing pipe 5 can only be blown outward by rotating to the blowing hole 214 parallel to the air outlet direction of the air outlet hole 51, so that the gas always keeps blowing toward the side of the rear end of the hot pressing roller 21 close to the conveying direction of the conveyor belt 1. The gas can blow the mask to force the surface of the mask that has been hot-pressed to separate from the outer peripheral wall of the hot pressing roller 216, reducing the possibility of the mask adhering to the surface of the hot pressing roller 21 located in the hot pressing mold area 211 and causing the mask to be wrapped around the peripheral wall of the hot pressing roller 216.

[0059] Embodiment 2:

[0060] The embodiment of the present application discloses a mask production device for printing patterns.

[0061] Reference Figure 4 , Figure 5 The difference between the mask production device for engraving patterns disclosed in the embodiment of the present application and the embodiment 1 is that:

[0062] In this embodiment, the air blowing pipe 5 is rotatably mounted on the mounting frame 11, and an elastic member 54 is installed between the air blowing pipe 5 and the mounting frame 11. The elastic member 54 is configured as a torsion spring, and the torsion spring is sleeved on the outer peripheral wall of the air blowing pipe 5. One end of the torsion spring is fixedly connected to the outer peripheral wall of the air blowing pipe 5 at one end away from the driving motor, and the other end of the torsion spring is fixedly connected to the side wall of the mounting frame 11. In the normal state of the torsion spring, the angle between the air outlet direction of the air outlet 51 and the surface of the conveyor belt 1 is maintained at 85 degrees.

[0063] Referring to Figure 4 、 Figure 5 、 Figure 6 There is a docking assembly 6 between the air blowing pipe 5 and the hot pressing roller 21. When the air blowing hole 214 rotates to communicate with the air outlet hole 51, the docking assembly 6 forces the air blowing pipe 5 to dock with the hot pressing roller 21 and forces the air blowing pipe 5 to rotate following the hot pressing roller 21; A limiting block 52 for detaching the air blowing pipe 5 from the hot pressing roller 21 is fixedly installed on the outer peripheral wall of the end of the air blowing pipe 5 far away from the driving motor, and the side wall of the mounting frame 11 close to the limiting block 52 has a convex portion 111; Specifically, when the air outlet direction of the air outlet hole 51 of the air blowing pipe 5 rotates following the hot pressing roller 21 to form an 80-degree angle with the surface of the conveyor belt 1, the limiting block 52 abuts against the side wall of the convex portion 111 and forces the air blowing pipe 5 to detach from the hot pressing roller 21.

[0064] Referring to Figure 5 、 Figure 6 、 Figure 7 A plurality of first embedding grooves 53 are formed on the outer peripheral wall of the air blowing pipe 5, and all the first embedding grooves 53 are arranged at intervals along the length direction of the air blowing pipe 5. A plurality of second embedding grooves 2152 are formed on the inner peripheral wall of the hot pressing core roller 215, and all the second embedding grooves 2152 are arranged at intervals around the central axis of the hot pressing core roller 215, and adjacent embedding grooves are arranged at intervals along the length direction of the hot pressing core roller 215.

[0065] Referring to Figure 6 、 Figure 7 The docking assembly 6 includes a first magnet 61 and a second magnet 62. A plurality of first magnets 61 are provided and all the first magnets 61 are arranged in one-to-one correspondence with all the first embedding grooves 53, and each first magnet 61 is embedded in the corresponding first embedding groove 53; A plurality of second magnets 62 are provided and all the second magnets 62 are arranged in one-to-one correspondence with all the second embedding grooves 2152, and each second magnet 62 is embedded in the corresponding second embedding groove 2152; All the first magnets 61 are arranged in one-to-one correspondence with all the second magnets 62, and all the second magnets 62 are arranged in one-to-one correspondence with all the air blowing holes 214. When the air blowing hole 214 rotates to communicate with the air outlet hole 51, the first magnet 61 is attracted to the second magnet 62 corresponding to the air blowing hole 214.

[0066] The implementation principle of Embodiment 2 of this application is as follows: When the air blowing holes 214 of the hot pressing roller 21 rotate to communicate with the air outlet holes 51, at this time, the first magnet 61 is attracted to the corresponding second magnet 62, so that the air blowing pipe 5 is butted against the hot pressing roller 21 and can rotate following the hot pressing roller 21; When the air blowing pipe 5 rotates following the hot pressing roller 21, it forces the torsion spring to deform. When the air outlet direction of the air outlet hole 51 rotates to form an 80-degree angle with the surface of the conveyor belt 1 driven by the hot pressing roller 21, at this time, the limiting block 52 abuts against the side wall of the convex part 111, thereby stopping the air blowing pipe 5. As the hot pressing roller 21 continues to rotate, the first magnet 61 can be separated from the second magnet 62, thereby forcing the air blowing pipe 5 to be separated from the hot pressing roller 21. The air blowing pipe 5 rotates and resets under the action of the torsion spring, so that the air outlet hole 51 of the air blowing pipe 5 is used to butt against the next air blowing hole 214. In this way, the air blowing pipe 5 can swing back and forth around its own central axis; When the air blowing pipe 5 swings following the hot pressing roller 21, the duration of the communication between the air outlet hole 51 and the air blowing hole 214 can be extended, thereby improving the air blowing effect of the air blowing hole 214 on the surface of the mask and further reducing the possibility of the mask being wound around the surface of the hot pressing roller 21.

[0067] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
