Description

Technical Field

[0001] The present invention relates to the technical field of ink printing of labels, and more particularly to a printing device for producing self-adhesive labels and a use method thereof. Background Art

[0002] Self-adhesive printing is to copy ink onto the self-adhesive label as the base paper. Taking the roller coating printing of self-adhesive labels as an example, the ink coating is supplied to the coating roller through the corresponding device, and the coating roller is evenly rotated to print it evenly on the surface of the coated label. Finally, it is dried and cured by drying equipment, so that the ink coating can be printed on the surface of the self-adhesive label in the form of a solid protective layer.

[0003] However, in the actual production process, because the ink is a paste-like adhesive body with a certain fluidity and is formed by a uniform mixture of colored bodies, binders and fillers, in order to ensure the stability of the color of the subsequently printed ink, it is necessary to ensure the dryness of the ink outlet. If the drying device is underpowered or the ambient temperature is too low, the ink will not adhere firmly and will easily fall off, making the printed pattern weak and blurred. In order to ensure the dryness of the ink, the prior art combines the corresponding matching desiccant to extend the drying time of the printed ink. However, this step is often performed by manual stirring and mixing, and then the mixed ink is poured onto the coating roller. The whole process is relatively cumbersome, especially in the mass printing production line of self-adhesive labels, where the mixed ink cannot be continuously replenished at intervals, affecting the printing efficiency of the overall production line.

[0017] A method for using a printing device for producing self-adhesive labels, comprising the following steps:

[0018] S1: First, the corresponding ink and additives are placed in the material storage box, and the reciprocating threaded rod at the output end is driven by the servo motor to drive the telescopic annular airbag sleeve to reciprocate and extrude and expand the rubber filling ring sleeve;

[0019] S2: Then, the material is output to the mixing bin of the mixing module during the reciprocating extrusion process, and the material in the material storage box is synchronously sucked in for self-replenishment during the resetting process of the rubber filling ring sleeve;

[0020] S3: Then the first crawler and the second crawler drive the stirring roller and the coating roller to rotate, so that the materials are dried and mixed in the hot air environment provided by the heating ring cover, and are discharged stably;

[0021] S4: Finally, after hot air is introduced into the rear side of the blowing chamber, the printed ink is dried for a second time by using the fan blades, and the fan blades on the side where no hot air is introduced are combined to blow dust to the surface of the self-adhesive label to be printed.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The independent ink supply and heating mechanism at the output end is driven by a linear motor to move along the feed end. When the roller printing machine is used for ink printing, it can adapt to more types and sizes of self-adhesive labels. In conjunction with the reciprocating rotation of the reciprocating threaded rod at the output end of the servo motor configured on the outside of the visible cylindrical cover, the retractable circular airbag sleeves on both sides can be controlled to reciprocate and retract to pull and unfold the rubber filling circular sleeve on the outside, and use negative pressure to suck in ink and corresponding additives. Under the action of subsequent extrusion force, the sucked materials are extruded into the stirring module, automatically completing the loading and feeding of ink and additives. In the process of batch ink printing, there is no need for manual repeated addition of materials, thereby improving the printing efficiency of the entire production line.

[0024] 2. Through the material storage boxes separately arranged on both sides of the outer surface of the visible cylindrical cover, not only can the ink and the corresponding additives be added at one time, so that they can be synchronously transported to the stirring module for mixing and stirring later, thereby ensuring the stability of the mixing end, but also the separate arrangement of the loading and mixing ends can be utilized to make the loading and feeding ends have a certain gap difference. Different from the prior art that requires stopping the machine for inking, when the material storage box is subsequently replenished, the loading can be completed without closing the printing end, which can further improve the printing efficiency of the entire production line.

[0025] 3. Through the reciprocating rotation of the reciprocating threaded rod, the telescopic annular airbag sleeves on both sides are controlled to reciprocate and retract to extrude and absorb materials. At the same time, the heating annular sleeve cover wrapped on the outside of the telescopic annular airbag sleeve will form hot air in its cavity under the action of reciprocating friction, and the hot air is transported to the stirring module and the blowing module through the configured duct, so that the stirring chamber where the ink is mixed has a certain temperature, ensuring the dryness and stability of the overall environment during the mixing process. At the same time, the hot air is blown out through the blowing module one after another, and the surface of the self-adhesive label to be printed can be dried with hot air at the same time, ensuring the thermal stability of the printed surface and making the ink adhesion more stable.

[0026] 4. Through the first crawler and the second crawler configured in the linkage module, under the drive of a single motor, the main rotating rod can be driven to rotate to absorb and replenish materials, and at the same time, two sets of stirring rollers can be driven to rotate in opposite directions for stirring, and the fan blades and paint rollers at the bottom can be driven to work in linkage, making the equipment more efficient in power transmission, reducing energy waste, and lowering the failure rate, making the adaptability of each division of labor in the overall working process higher, increasing the overall fault tolerance rate on the production line, and ensuring that it can stably and smoothly complete inking and inking.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] Reference Figures 1 to 10 The present invention further describes a printing device for producing self-adhesive labels and an embodiment of the method for using the same.

[0041] A printing device for producing self-adhesive labels, comprising a roller printing machine 1 and a linear motor 2, wherein the linear motor 2 is fixedly mounted at the upper side of the printing paper input end of the roller printing machine 1, a supporting hanging plate 3 is fixedly mounted on the output end of the linear motor 2, an independent ink supply and heating mechanism 4 is arranged on the outer side of the supporting hanging plate 3, and a stirring module 5, a blowing module 6, a discharging module 7 and a linkage module 8 are arranged at the bottom of the independent ink supply and heating mechanism 4;

[0042] The independent ink supply and heating mechanism 4 comprises a cylindrical frame 41 and a servo motor 44 disposed at the outer end of one side of the cylindrical frame 41. Reciprocating threaded rods 46 are disposed at both sides of the cylindrical frame 41 through the output ends of the servo motor 44; and a telescopic annular airbag sleeve 415 and a rubber patching annular sleeve 416 are disposed on the reciprocating threaded rod 46 on each side.

[0043] Among them, the outer side of the telescopic annular airbag cover 415 is covered with a heating annular cover 412. Through the reciprocating driving action of the reciprocating threaded rod 46, the telescopic annular airbag cover 415 reciprocates and rubs against the inner wall of the heating annular cover 412 to increase the temperature; and at the same time, the ink and additives in the rubber patch annular covers 416 on both sides are automatically squeezed into the stirring module 5 for mixing and stirring; and the hot air generated by the friction of the inner wall of the heating annular cover 412 is blown out to the side of the discharging module 7 in cooperation with the blowing module 6 to dry the ink in real time.

[0044] Aiming at the problem that the self-adhesive label in the prior art cannot automatically complete the mixing and self-replenishing of ink and additives during the roller coating printing process, and it is difficult to ensure the dryness of the ink outlet end, the above-mentioned technical scheme is now adopted to solve the problem. The above-mentioned technical scheme mainly consists of a roller printing machine 1, a linear motor 2, an independent ink supply and heating mechanism 4, a stirring module 5, a blowing module 6, a discharge module 7 and a linkage module 8. The roller printing machine 1 is a roller printing device in the prior art, and the self-adhesive label is brought in for printing through the roller on its input end. The configured linear motor 2 is also a motor device used for linear drive in the prior art, which is used to drive the supporting suspension plate 3 to move linearly. The discharge path of the discharge module 7 is controlled to print self-adhesive labels of different sizes. During the working process, the servo motor 44 configured in the independent ink supply and heating mechanism 4 causes the reciprocating threaded rods 46 symmetrical on both sides to reciprocate, driving the telescopic annular airbag sleeves 415 on both sides to reciprocate and retract, so that the rubber filling annular sleeve 416 squeezes and sucks, and the ink and additives stored on the outside are replenished into the device in intervals for intermittent mixing. The inner wall of the annular sleeve cover 412 is heated by reciprocating friction through the telescopic annular airbag sleeve 415 to increase the temperature, and the generated hot air is introduced into the stirring module 5 and the blowing module 6 to dry the entire ink mixing end and the extrusion end, thereby improving the adhesion of the ink printing.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a visible cylindrical cover 42 is fixedly installed on the outer surface of the cylindrical frame 41, an outer extension frame 43 is fixedly installed on the outer end of one side of the cylindrical frame 41, a servo motor 44 is fixedly installed on the outer surface of the outer extension frame 43, a main rotating rod 45 is fixedly connected to the output end of the servo motor 44, and the main rotating rod 45 as a whole penetrates from the center position of one end of the visible cylindrical cover 42; and penetrates from the other end of the visible cylindrical cover 42, reciprocating threaded rods 46 are fixedly connected at symmetrical positions on both sides of the main rotating rod 45; and a nut sleeve 47 is meshingly installed on the outer surface of the reciprocating threaded rod 46 on each side.

[0046] Among them, the configured cylindrical frame 41 and the visible cylindrical cover 42 are an integrated structure, and the overall structure is a cylindrical frame structure of a visible shape. It serves as the main frame structure of an independent ink supply and heating mechanism 4, and uses a servo motor 44 configured on one side end to drive the main rotating rod 45 at the output end to rotate inside the visible cylindrical cover 42. The reciprocating threaded rod 46 is symmetrically distributed on both sides of the main rotating rod 45, and the round rod radius of the reciprocating threaded rod 46 is smaller than the round rod radius of the main rotating rod 45 to prevent disengagement and limit the position.

[0047] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, auxiliary circular ring sleeves 410 are fixedly installed on both sides of the inner wall of the visible cylindrical cover 42 at the positions of the two ends of the reciprocating threaded rod 46; and guide rail frames 411 arranged on both sides of the reciprocating threaded rod 46 are fixedly connected between the two auxiliary circular ring sleeves 410, and convex wings slidingly clamped in the guide rail frames 411 are arranged on both sides of the nut sleeve 47, and a U-shaped outrigger rod frame 48 is fixedly connected to the outer side of the U-shaped outrigger rod frame 48, and a first circular partition plate 49 is fixedly installed on the outer side of the U-shaped outrigger rod frame 48.

[0048] Among them, the configured auxiliary circular ring sleeve 410 is a supporting member for a tower base arranged on the guide rail frames 411 on both sides of the reciprocating threaded rod 46. The outside of the reciprocating threaded rod 46 on each side is meshed with a nut sleeve 47. In order to ensure that the nut sleeve 47 can move stably on the reciprocating threaded rod 46, convex wings are arranged on both sides of the outer circular surface of the nut sleeve 47 for sliding and clamping in the guide rail frames 411 on both sides for limiting. During the rotation of the reciprocating threaded rod 46, the meshed nut sleeve 47 can move back and forth along the guide rail frame 411, and the U-shaped protruding rod frame 48 outside the nut sleeve 47 is used to push the first circular partition 49 outward.

[0049] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the outer surface of the first annular partition 49 is fixedly installed with a telescopic annular airbag sleeve 415, and the outer side of the telescopic annular airbag sleeve 415 is fixedly installed with a rubber patch annular sleeve 416. The first annular partition 49, the telescopic annular airbag sleeve 415, and the rubber patch annular sleeve 416 are integrally sleeved on the main rotating rod 45 on the corresponding side; and the outer end of the rubber patch annular sleeve 416 on each side is fixedly installed with a second annular partition 417 fixedly connected to the inner wall of the cylindrical frame 41.

[0050] Among them, the configured telescopic ring airbag sleeve 415 is a resettable telescopic ring airbag sleeve structure in the prior art, and its shape is similar to the buffer telescopic sleeve structure in the prior art. Under the extrusion state, it can discharge the internal gas to fold, and can restore by sucking air through the set air holes in the absence of extrusion force. The corresponding rubber patch ring sleeve 416 is a resettable rubber ring sleeve structure in the prior art, and its working principle is the same as that of the telescopic ring airbag sleeve 415.

[0051] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, material storage boxes 418 are fixedly installed at both sides of the outer surface of the visible cylindrical cover 42, and the bottom of the material storage box 418 is fixedly connected with a second conduit 419 which is connected to the top of the side of the rubber filling ring sleeve 416 on the corresponding side, and reserved discharge ports 423 are fixedly installed at the bottom of both sides of the visible cylindrical cover 42, and third conduits 420 which are connected to the reserved discharge ports 423 on the corresponding side are fixedly connected at the bottom of the side of the rubber filling ring sleeve 416 on both sides of the visible cylindrical cover 42.

[0052] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, fourth conduits 422 are fixedly installed at both sides of the outer surface of the visible cylindrical cover 42, and heating circular ring covers 412 are fixedly installed at both sides of the inner wall of the visible cylindrical cover 42 at the positions outside the telescopic circular ring airbag cover 415. The heating circular ring cover 412 is a circular ring-shaped cavity structure as a whole; and a friction coating 413 is fixedly installed on the end of the inner wall that contacts the outer surface of the telescopic circular ring airbag cover 415, and a first conduit 414 corresponding to the fourth conduit 422 on the corresponding side is fixedly connected to the heating circular ring cover 412.

[0053] The material storage box 418 is a storage box structure for storing liquid in the prior art, and is provided with a corresponding sealing cover and a capacity plate. The second conduit 419 and the third conduit 420 are both provided with a one-way valve body. Under the control of the one-way valve body in the second conduit 419, the liquid can only be sucked out from the bottom of the material storage box 418, and the corresponding third conduit 420 can only squeeze out the liquid from the bottom of the rubber filling ring sleeve 416 under the control of the one-way valve body, so as to facilitate the overall control. The friction coating 413 arranged on the inner wall of the heating ring sleeve 412 is a cloth capable of generating heat by friction in the prior art, and the heat source generated by the frictional heat will be transported to the heating ring sleeve 412.

[0054] The working principle of the independent ink supply heating mechanism 4 is:

[0055] Before work: According to the needs of self-adhesive label printing, select the ink of the corresponding color and category, and add it to the material storage box 418 on one side of the visual cylinder cover 42, and then select the corresponding mixed additive according to the type of ink added. If the additive is in a viscous state, such as a viscous or emulsion state enhancer, it can be added to the material storage box 418 on the other side of the outer surface of the visual cylinder cover 42. When the additive is not in a viscous state, such as a liquid diluent, it can be directly added to the material storage box 418 on one side together with the ink;

[0056] During operation: through the servo rotation of the main rotating rod 45 at the output end of the servo motor 44, the rotation speed of the main rotating rod 45 is controlled, so that the reciprocating threaded rods 46 on both sides rotate evenly, driving the meshing nut sleeve 47 to reciprocate along the outer guide rail frame 411. When the nut sleeve 47 moves outward, the U-shaped extension rod frame 48 on the outer side of the nut sleeve 47 will cooperate with the first circular ring partition 49 to extrude the telescopic circular ring airbag sleeve 415 outward, so that the telescopic circular ring airbag sleeve 415 is folded, and further squeezes the rubber patch circular ring sleeve 416 on the side to flatten the rubber patch circular ring sleeve 416 and squeeze the rubber patch circular ring sleeve 416. The ink in the feeding ring sleeve 416 is squeezed out from the third conduit 420 at the bottom thereof, and is squeezed into the stirring module 5 at the bottom through the reserved discharge port 423, and is subsequently mixed. When the nut sleeve head 47 rotates to the end of the reciprocating threaded rod 46, it rotates back and forth, and the folded integral telescopic ring airbag sleeve 415 and the rubber feeding ring sleeve 416 are reset when rotating back. During the reset process of the rubber feeding ring sleeve 416, the cavity in the rubber feeding ring sleeve 416 forms a negative pressure, so that the second conduit 419 sucks the liquid material from the material storage box 418. The reciprocating rotation can intermittently load and feed the materials;

[0057] Furthermore, in the process of the reciprocating threaded rod 46 driving the telescopic annular airbag sleeve 415 to move back and forth, the telescopic annular airbag sleeve 415 will reciprocately rub against the inner wall of the heating annular sleeve cover 412, and reciprocate with its friction coating 413. The cavity of the heating annular sleeve cover 412 will generate friction heat during the reciprocating friction process, and the heat source will be transported to the cavity of the heating annular sleeve cover 412 and output to the outside through the first conduit 414 on the outside of the heating annular sleeve cover 412 to generate heat for subsequent modules.

[0058] like Figure 2 , Figure 3 , Figure 7 As shown, the stirring module 5 includes a stirring chamber 51 fixedly installed at both sides of the bottom of the visible cylindrical cover 42, and two groups of stirring rollers 52 are movably installed in the stirring chamber 51, one in front and one in the back.

[0059] like Figure 2 , Figure 3 , Figure 7 As shown, the fourth duct 422 is a Y-shaped two-way duct as a whole, the side of the stirring chamber 51 is fixedly connected with a fifth duct 57 corresponding to the fourth duct 422 on the corresponding side, and the sixth duct 65 corresponding to the fourth duct 422 on the corresponding side is fixedly installed at both ends of the side of the blowing chamber 61, and fan blades 62 are fixedly installed on the shafts of the two groups of stirring rollers 52 passing through and entering the interior of the blowing chamber 61; and a partition plate 63 is fixedly installed at the position between the two fan blades 62 in the interior of the blowing chamber 61, and exhaust cover plates 64 corresponding to the fan blades 62 are fixedly installed on both sides of the blowing chamber 61.

[0060] Among them, the stirring rollers 52 and fan blades 62 in the stirring chamber 51 and the blowing chamber 61 are an integrated structure, and the meshing driving action of the second gear head 53 and the third gear head 54 on the outside can drive the three working ends to work synchronously, and the interfaces of the connected shafts are provided with sealing rings, and the front and rear stirring rollers 52 are arranged crosswise in pairs to better pull the ink to stir, and a number of stirring rods are arranged on the outer surface of each stirring roller 52, and the front and rear fan blades 62 separated by the partition plate 63 are arranged in a front-to-back symmetrical structure, so that when the two stirring rollers 52 rotate towards each other, both sides can stably rotate outward to discharge wind.

[0061] like Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown, the discharging module 7 includes a mixing box 71 fixedly installed at the bottom of the mixing bin 51 and the blowing bin 61, the upper side of the mixing box 71 is communicated with the bottom of the two mixing bins 51, and coating rollers 72 are movably installed at the front and rear sides of the mixing box 71, and both ends of the coating rollers 72 are fixedly connected with feeding impellers 73; and one end of the feeding impellers 73 on the outside of the two groups of coating rollers 72 passes through the mixing box 71 and are fixedly connected with the sixth gear head 74; and the two sixth gear heads 74 are meshed with each other and correspond to each other; and a coaxial seventh gear head 75 is fixedly connected to the outer surface of one of the sixth gear heads 74.

[0062] like Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown, the linkage module 8 includes a second gear head 53, a third gear head 54, a sixth gear head 74 and a seventh gear head 75; it also includes a first gear head 421 fixedly mounted on the end of the main rotating rod 45 away from the servo motor 44, a fourth gear head 55 coaxially fixedly mounted on the outer surface of the second gear head 53, a fifth gear head 56 coaxially fixedly mounted on the outer surface of the third gear head 54, the fourth gear head 55 is meshed with the outer side of the first gear head 421 to form a first track 81, and the fifth gear head 56 is meshed with the outer side of the seventh gear head 75 to form a second track 82.

[0063] The configured mixing box 71 is an inverted trapezoidal structure as a whole, which has the function of gathering liquid toward the middle end of the bottom. The feeding blades 73 at the inclined ends on both sides of the mixing box 71, that is, at both sides of the coating roller 72, are outward-expanding blades as a whole, which are convenient for stably rolling up the ink for output. An ink outlet opening is opened in the middle of the bottom of the configured mixing box 71 at the position of the bottom of the two coating rollers 72.

[0064] The mixing process of the stirring module 5 is as follows: when the independent ink supply and heating mechanism 4 reciprocates through the telescopic annular airbag sleeve 415, and the ink and additives are injected into the stirring chambers 51 on both sides from one end of the reserved discharge port 423, when the first crawler 81 on the outside of the first gear head 421 drives the fourth gear head 55 on the outside of the second gear head 53 to rotate, due to the meshing action, the second gear head 53 and the third gear head 54 rotate in opposite directions, and the internal stirring rollers 52 are controlled to rotate in opposite directions, and the dropped additives and ink are stirred by the force of the opposite rotation, and at the same time, the fan blades 62 on both sides of the blowing chamber 61 are controlled to rotate in opposite directions for blowing;

[0065] Furthermore, the hot air generated in the heating annular cover 412 will be transported to the position of the fourth duct 422 through the first duct 414. By utilizing the Y-shaped design of the fourth duct 422, part of the hot air will be transported to the mixing chamber 51, and the other part will be transported to the blowing chamber 61. The hot air entering the mixing chamber 51 will dry the area. Similarly, the hot air entering the partition at the rear side of the blowing chamber 61 will be blown outward in combination with the fan blades 62, and the hot air will be blown toward the input end of the roller printing machine 1 to dry the ink printed by the printing end, so as to ensure that the ink layer is adhered to the ink as much as possible. The ink and additives stirred in the mixing chamber 51 will enter the mixing box 71 at the bottom. At the same time, the rotating fifth gear head 56 will control the seventh gear head 75 on the outside of the mixing box 71 to rotate under the driving action of the second crawler 82, and drive the two meshing sixth gear heads 74 to rotate. Under the gathering effect of the mixing box 71, the ink and additives are rolled out to the ink outlet end at the bottom of the mixing box 71 through the oppositely rotating feeding blades 73 and mixed. After being rolled out by the coating roller 72, they can leak out at the front bottom position of the roller printing machine 1, completing the ink supply.

[0066] Instructions for use: First, configure the corresponding ink and additives in the material storage box 418, and drive the reciprocating threaded rod 46 at the output end of the servo motor 44 to drive the retractable annular airbag sleeve 415 to reciprocate and extrude, and unfold the rubber filling annular sleeve 416, inject the material into the mixing chamber 51 of the mixing module 5, and simultaneously suck the material storage box 418 for self-replenishment. During the process, the first track 81 and the second track 82 are used to drive the mixing roller 52 and the coating roller 72 to rotate, so that the material is dried and mixed in the hot air environment provided by the heating annular sleeve 412, and discharged stably. After the hot air is introduced into the rear side of the blowing chamber 61, the fan blades 62 can be used to perform secondary drying of the printed ink, and the fan blades 62 on the side where no hot air is introduced will blow air to the surface of the self-adhesive label to be printed, thereby improving the cleanliness of the printed surface.
