DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Example 1: Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a printing device for processing self-adhesive labels includes a support table 1, a printing base plate 2 is slidably arranged in the middle of the support table 1, a label belt (not shown in the figure) is arranged on the upper side of the printing base plate 2, side plates 9 are vertically fixedly arranged on the front and rear sides of the support table 1, a rotating drum 4 is rotatably arranged between the two side plates 9, the rotating drum 4 adopts a hollow cylindrical structure with one end sealed and the other end open, a servo motor 21 for driving the rotating drum 4 to rotate is fixedly arranged on the rear side of the side plate 9, a connecting drum 5 is concentrically fixedly arranged on the outer side of the rotating drum 4, and the connecting drum 4 is connected to the rotating drum 4. 5 is movably provided with a plurality of arc-shaped printing plates 6 cooperating with the printing base plate 2 on the outer side thereof. In the present embodiment, six arc-shaped printing plates 6 are provided, and the specific number can be flexibly adjusted according to the size of the printed pattern. When in use, the servo motor 21 drives the rotating drum 4 to rotate, and then drives the connecting drum 5 on the outer side of the rotating drum 4 to rotate, so that the plurality of arc-shaped printing plates 6 on the connecting drum 5 rotate. When the six arc-shaped printing plates 6 rotate, they squeeze the label tape on the upper side of the printing base plate 2, so that the pattern on the arc-shaped printing plates 6 is printed on the upper surface of the label tape, and printing is completed.

[0033] like Figure 1 , Figure 2 , Figure 7 , Figure 8As shown, six buffer mechanisms 7 connected to the curved printing plates 6 are fixedly arranged on the inner side of the connecting cylinder 5. The buffer mechanism 7 includes a fixed cylinder 701 fixedly arranged on the inner side of the connecting cylinder 5, a buffer spring 702 fixedly arranged on the inner side of the fixed cylinder 701, a slide plate 703 slidably connected to the inner side of the fixed cylinder 701 is fixedly arranged on one end of the buffer spring 702, and a slide bar 704 slidably penetrating the connecting cylinder 5 and fixedly connected to the inner side of the curved printing plates 6 is fixedly arranged on one side of the slide bar 703. When in use, when the connecting cylinder 5 drives the six curved printing plates 6 thereon to rotate, and when the curved printing plates 6 squeeze the label tape on the upper side of the printing base plate 2, the curved printing plates 6 will move to one side of the connecting cylinder 5, so that the slide bar 704 on the inner side of the curved printing plates 6 is moved on the fixed cylinder 701. The inner side slides and then compresses the buffer spring 702 inside the fixed cylinder 701, and the elastic force of the buffer spring 702 can be used to press against the slide plate 703, so that the slide bar 704 squeezes the arc printing plate 6, and then the arc printing plate 6 is tightly pressed against the surface of the label tape on the upper side of the printing base plate 2, so that the printing is clearer and the printing quality is improved. In addition, since the arc printing plate 6 rotates with the connecting cylinder 5, the distance between the arc printing plate 6 and the surface of the label tape changes from large to small and then becomes large, so the elastic force of the buffer spring 702 changes from small to large and then becomes small, so that the pressure of the arc printing plate 6 on the label tape changes from small to large and then becomes small, so that the printing pressure changes, the printing quality is improved, and the time that the arc printing plate 6 is pressed on the label tape can be increased, further improving the printing quality.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, a horizontally arranged top plate 10 is fixedly provided at the upper ends of the two side plates 9, and an ink unloading mechanism cooperating with the curved printing plate 6 is provided on the upper side of the top plate 10. The ink unloading mechanism includes an ink guide tube 11 fixedly passing through the middle of the top plate 10, and an opening is provided at the lower end of the ink guide tube 11. A sponge block 13 extending out of the opening and cooperating with the curved printing plate 6 is provided on the inner side of the ink guide tube 11. Since the ink has a certain viscosity, the ink will adhere to the inside of the sponge block 13 and will not cause the ink to drip. The lower end of the sponge block 13 is slightly lower than the upper surface of the uppermost curved printing plate 6, which is convenient for the curved printing plate 6 to squeeze the sponge block 13, so that the ink inside the sponge block 13 is coated on the surface of the curved printing plate 6, and the ink can be evenly coated on the surface of the curved printing plate 6 through the soft sponge block 13, so that printing is more uniform and the printing quality is improved. An ink cylinder 14 is fixedly provided on the upper side of the top plate 10, and an ink inlet pipe 20 is provided on the upper side of the ink cylinder 14. The tube 20 can add new ink. The front side of the ink cartridge 14 is provided with an observation window 1401. The observation window 1401 is convenient for observing the remaining ink in the ink cartridge 14, so that ink can be added in time, so that printing can be carried out continuously and the printing efficiency can be improved. The lower side of the ink cartridge 14 is fixedly connected with a plurality of lower ink tubes 12 fixedly connected with the upper end of the ink guide tube 11. In this embodiment, three lower ink tubes 12 are provided, and the specific number can be flexibly adjusted according to the type of ink to adjust the ink feeding rate. Several lower ink tubes 12 are provided with valves 1201. The ink feeding rate can be adjusted through the valves 1201 to prevent the ink from being fed too quickly and causing ink to splash out. When in use, by opening the valve 1201, the ink inside the ink cartridge 14 can flow into the interior of the ink guide tube 11 through the lower ink tube 12, and then the ink penetrates into the interior of the sponge block 13, so that the sponge block 13 can evenly apply the ink to the outer surface of each curved printing plate 6, thereby improving the uniformity of printing.

[0035] like Figure 1 , Figure 2 As shown, a stirring assembly is provided on the inner side of the ink cartridge 14, and the stirring assembly includes a stirring shaft 15 rotatably provided on the inner side of the ink cartridge 14, and a stirring bracket 1501 located inside the ink cartridge 14 is fixedly provided on the stirring shaft 15, and the upper end of the stirring shaft 15 rotates and penetrates the ink cartridge 14. During the printing process, the stirring bracket 1501 is driven to rotate by the stirring shaft 15, so that the ink inside the ink cartridge 14 is stirred, so as to prevent the upper surface of the ink from solidifying due to long-term stillness, prevent the fluidity of the ink from being affected, and improve the smoothness of ink feeding.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, a transmission mechanism 16 for driving the stirring assembly to rotate is arranged on the outer side of the ink cartridge 14, and the transmission mechanism 16 includes a driven bevel gear 1608 fixedly sleeved on the upper end of the stirring shaft 15, and an active bevel gear 1601 is fixedly arranged on the output end of the servo motor 21, and a first transmission bevel gear 1602 is meshed on the upper side of the active bevel gear 1601, and a first transmission rod 1603 is fixedly arranged on the upper side of the first transmission bevel gear 1602, and a second transmission bevel gear 160 is fixedly arranged on the upper end of the first transmission rod 1603. 4, a third transmission bevel gear 1605 is meshed on one side of the second transmission bevel gear 1604, a second transmission rod 1606 is fixedly provided on one side of the third transmission bevel gear 1605, a fourth transmission bevel gear 1607 meshed with the driven bevel gear 1608 is fixedly provided on one end of the second transmission rod 1606, a first limit bearing 1609 fixedly connected to the side plate 9 is provided on the first transmission rod 1603, and a second limit bearing 1610 fixedly connected to the upper side of the ink cartridge 14 is provided on the second transmission rod 1606. 0, when in use, when the servo motor 21 drives the rotating drum 4 and the connecting drum 5 to rotate, and during the printing process of the arc printing plate 6, the servo motor 21 can also drive the active bevel gear 1601 to rotate, and then the first transmission bevel gear 1602 to rotate, so that the first transmission rod 1603 rotates under the limiting action of the first limiting bearing 1609, drives the second transmission bevel gear 1604 at the upper end of the first transmission rod 1603 to rotate, so that the third transmission bevel gear 1605 meshing therewith rotates, so that the second transmission rod 1606 rotates under the limiting action of the second limiting bearing 1610, drives the fourth transmission bevel gear 1607 at one end of the second transmission rod 1606 to rotate, so that the driven bevel gear 1608 meshing therewith rotates, and can drive the stirring shaft 15 of the inner ring of the driven bevel gear 1608 to rotate, and then drives the stirring bracket 1501 on the stirring shaft 15 to rotate, so that the label tape automatically stirs the ink inside the ink tube 14 during printing to prevent the ink from agglomerating and affecting the use effect of the ink.

[0037] Embodiment 2: Based on embodiment 1, further improvement is made in that Figure 1 , Figure 3 , Figure 4 , Fig. 9 , Fig.10As shown, a vertically penetrating slide groove 18 is provided in the middle of the support platform 1, and the printing base plate 2 is slidably arranged on the inner side of the slide groove 18. The front and rear side walls of the slide groove 18 are provided with guide grooves 19. Guide blocks slidably connected to the inner side of the guide groove 19 are fixedly provided on the front and rear sides of the printing base plate 2. A reset spring 3 fixedly connected to one end of the slide groove 18 is fixedly provided on one side of the printing base plate 2. A brush 17 is fixedly provided on the side of the printing base plate 2 away from the reset spring 3. The upper side of the brush 17 is higher than the upper surface of the support platform 1. The brush 17 can brush away the dust on the lower surface of the label belt. A plurality of punching grooves 201 are provided on the printing base plate 2, and a plurality of penetrating connecting cylinders 5 are fixedly connected to the outer side of the rotating cylinder 4 and cooperate with the punching grooves 201. The punching tube 8 has a straight slot structure, so that when the punching tube 8 rotates and slides into the inner side of the punching slot 201, the punching tube 8 can rotate in a circle and pull the punching slot 201, so that the printing base plate 2 moves together, and the punching slot 201 with a straight slot structure can provide space for the punching tube 8 to move, so as to prevent damage to the punching tube 8. The punching tube 8 is arranged in six rows, each row is provided with a plurality of punching tubes 8, and the six rows of punching tubes 8 are staggered with the six arc-shaped printing plates 6. The punching tube 8 adopts a central cylindrical structure with two ends passing through. The punching end of the punching tube 8 is provided with a circular knife, and the circular knife at the punching end of the punching tube 8 is located between two adjacent arc-shaped printing plates 6. The punching ends of the punching tubes 8 are lower than the arc. The outermost side of the curved printing plate 6 is convenient for pressing and printing first, and then performing breakpoint punching. When in use, when the rotating drum 4, the connecting drum 5 and the curved printing plate 6 rotate, when the curved printing plate 6 presses the label tape on the upper side of the printing base plate 2, since the curved printing plate 6 is close to the connecting drum 5, the punching drum 8 on the outer side of the rotating drum 4 will extend relative to the curved printing plate 6, so that the punching drum 8 will perform breakpoint punching on the label tape, that is, the position of the breakpoint punching is between two adjacent curved printing plates 6, that is, the part without printed patterns. In the process of breakpoint punching, the punching drum 8 passes through the label tape and is inserted into the inner side of the punching slot 201 on the printing base plate 2. When the rotating drum 4 continues to drive the curved printing plate 6 to rotate, the rotating drum 4 will drive the punching drum 8 to rotate. The punching cylinder 8 is inserted into the inner side of the punching slot 201 and pushes the inner side wall of the punching slot 201, so that the printing base plate 2 slides with the label tape on its upper side, and at the same time, the reset spring 3 on one side of the printing base plate 2 is stretched. When the rotating cylinder 4 drives the punching cylinder 8 to disengage from the punching slot 201, the reset spring 3 will pull the printing base plate 2 to reset. During the reset process, the lower end of the punching cylinder 8 is still against the inner side of the breakpoint punching of the label tape. Therefore, when the printing base plate 2 is reset, it will drive the brush 17 on one side of the printing base plate 2 to slide on the lower surface of the label tape, so that the dust on the lower surface of the label tape is brushed off. Since the label tape is subsequently wound inside and outside in an alternating manner, dust can be prevented from falling into the ink part of the label tape during winding, thereby affecting the printing quality.

[0038] like Figure 4 , Figure 6 , Fig.11 As shown, the front side of the side plate 9 is provided with an air intake mechanism 24 for blowing air into the inner side of the rotating drum 4. The air intake mechanism 24 includes an adapter 2401 fixedly arranged on the front side of the side plate 9 and rotatably connected to the rotating drum 4. The adapter 2401 is installed on the front side of the side plate 9 through a fixed bracket. One end of the adapter 2401 is fixedly connected with an air intake pipe 2402. One end of the air intake pipe 2402 is connected with a hot air blower (not shown in the figure). During the printing process, the hot air blower blows hot air into the inner side of the rotating drum 4 through the adapter 2401, and then blows the hot air into the inner sides of the plurality of punching cylinders 8 through the rotating drum 4, and finally passes through the punching cylinders 8. The punching end of the hole cylinder 8 is blown out, and the dust on the surface of the label tape can be blown away through the punching cylinder 8 on the left before the label tape slides into the printing base plate 2, so as to prevent the printing quality from being affected during printing. The ink on the surface of the label tape after printing can be dried through the punching cylinder 8 on the right to improve the pattern setting efficiency. The ink inside the sponge block 13 can be preheated and softened through the punching cylinder 8 on the upper side, so that when the arc printing plate 6 squeezes the sponge block 13, the ink inside the sponge block 13 can flow and be evenly coated on the surface of the arc printing plate 6, thereby improving the printing quality.

[0039] like Figure 5 , Figure 6 As shown, two support plates 22 are fixedly provided at one end of the upper side of the support platform 1, and a label unwinding roller 23 is provided on the upper side of the two support plates 22. Limiting grooves are provided at the top ends of the two support plates 22 for supporting the two ends of the limited label unwinding roller 23, and a label tape with or without a printed pattern is wound around the label unwinding roller 23.

[0040] It should be noted that, when the printing device used for the self-adhesive label processing is used, ink is poured into the interior of the ink cartridge 14 through the ink inlet pipe 20, and then the valve 1201 is opened, so that the ink inside the ink cartridge 14 flows into the interior of the sponge block 13 inside the ink guide tube 11 through the lower ink pipe 12, and the label unwinding roller 23 is mounted on two support plates 22, and the label tape on the label unwinding roller 23 is pulled out and laid on the upper side of the printing base plate 2, and then the servo motor 21 drives the rotating drum 4 to rotate counterclockwise, and then drives the connecting drum 5 outside the rotating drum 4 to rotate, so that the several curved printing plates 6 on the connecting drum 5 rotate, and the six curved printing plates 6 will squeeze the label tape on the upper side of the printing base plate 2 when rotating, so that the curved printing plates 6 The pattern is printed on the upper surface of the label tape. When the curved printing plate 6 rotates to the lower side of the top plate 10, the curved printing plate 6 will squeeze the sponge block 13, so that the sponge block 13 automatically and evenly applies the ink to the outer surface of each curved printing plate 6. During the ink discharge process inside the ink tube 14, the servo motor 21 can also drive the active bevel gear 1601 to rotate, thereby rotating the first transmission bevel gear 1602, so that the first transmission rod 1603 rotates under the limiting action of the first limiting bearing 1609, driving the second transmission bevel gear 1604 at the upper end of the first transmission rod 1603 to rotate, so that the third transmission bevel gear 1605 meshing therewith rotates, so that the second transmission rod 1606 rotates under the limiting action of the second limiting bearing 1610. The fourth transmission bevel gear 1607 at one end of the second transmission rod 1606 rotates, so that the driven bevel gear 1608 meshing with it rotates, which can drive the stirring shaft 15 of the inner ring of the driven bevel gear 1608 to rotate, and then drive the stirring bracket 1501 on the stirring shaft 15 to rotate, so that the label tape automatically stirs the ink inside the ink cartridge 14 during the printing process, and in the printing process, the arc printing plate 6 squeezes the slide bar 704 to slide on the inner side of the fixed cylinder 701, and then compresses the buffer spring 702 inside the fixed cylinder 701, so that the arc printing plate 6 is close to the connecting cylinder 5, which will make the punching cylinder 8 on the outer side of the rotating cylinder 4 extend relative to the arc printing plate 6, so that the punching cylinder 8 punches the label tape at the breakpoints, and punches the breakpoints. During the process, the punching cylinder 8 passes through the label tape and is inserted into the inner side of the punching slot 201 on the printing base plate 2. When the rotating drum 4 continues to drive the curved printing plate 6 to rotate, the rotating drum 4 will drive the punching cylinder 8 to rotate, so that the punching cylinder 8 is inserted into the inner side of the punching slot 201 and pushes the inner side wall of the punching slot 201, so that the printing base plate 2 slides with the label tape on its upper side. Through the movement of the label tape, the label tape can be automatically transported, so that the next section of the label tape can be printed for the next time. This can be done sequentially, so that printing can be carried out continuously, so that the printing efficiency is improved, and at the same time, the reset spring 3 on one side of the printing base plate 2 is stretched. When the rotating drum 4 drives the punching cylinder 8 to disengage from the punching slot 201, the reset spring 3 will pull the printing base plate 2 to reset. During the reset process,The lower end of the punching cylinder 8 is still against the inner side of the breakpoint punching of the label tape, so when the printing base plate 2 is reset, it will drive the brush 17 on one side of the printing base plate 2 to slide on the lower surface of the label tape, so that the dust on the lower surface of the label tape is brushed off. During the printing process, since the rotating drum 4 continuously drives the punching cylinder 8 to rotate, when the punching cylinder 8 rotates to the left, the dust on the upper surface of the label tape is blown away, and when it rotates to the right, the ink on the upper surface of the label tape after printing is dried. When the punching cylinder 8 rotates to the position of the sponge block 13, the ink inside the sponge block 13 is preheated and softened, so that when the curved printing plate 6 squeezes the sponge block 13, the ink inside the sponge block 13 flows and is evenly coated on the surface of the curved printing plate 6.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
