Description

Technical Field

[0001] The present invention relates to the technical field of continuous printing of packaging art paper, and specifically to an automatic embossing and printing device for packaging art paper. Background Technique

[0002] Embossing is a common processing technology for packaging materials. Using a mold with concave and convex patterns, the paper is deformed under the action of moving pressure and temperature to form certain patterns. The pressing methods are divided into flat embossing and roller embossing.

[0003] The prior art discloses a Chinese patent with the application number CN202210156807.9, an environment-friendly color printing product and its production process, which discloses that by closing the upper template and the lower template, the paper can be pressed, so that the initial paper print forms an embossed paper print. After the paper pressing is completed, gas is injected into the air holes on the upper template and the lower template through the air pressure system, so that the upper surface and the lower surface of the paper can be blown, making it convenient for the paper after jade forming to separate from the upper template and the lower template, and avoiding the paper from adhering to the engraved upper template or the lower template after printing.

[0004] The above device can make it better demold through the injection of gas after printing the paper products. However, in the embossing and printing of roll printing, in order to ensure the uniformity of the embossed pattern ink, the ink needs to be continuously applied. Therefore, an embossing and printing device that can automatically apply ink to the embossing roller is required. Summary of the Invention

The upper end of the ink control member seals the connection between the ink receiving box and the spiral pipe.

[0011] The cleaning unit includes two symmetrically arranged smoothing plates. In the middle of the smoothing plates, a round rod fixedly connected to the base plate is rotatably installed.

[0016] One-way valves are provided in the air blowing openings. Resistance members placed on the base plate are provided at one ends of the unwinding roller and the winding roller, and notches for guiding the wrapping paper are provided on the resistance members.

[0017] Advantages of the present invention:

[0018] 1. In the present invention, the electric slider is turned on to rotate, so that the winding roller and the unwinding roller respectively cooperate in winding and unwinding the wrapping paper during embossing printing. The two clamping frames are made to approach or move away from each other by the telescoping of the double-headed push rod, so as to disassemble and assemble different embossing rollers. Different flower patterns are set on different embossing rollers to meet different embossing printing requirements of the wrapping paper. When the motor is turned on to drive the embossing roller to rotate, the wrapping paper can be embossed and printed on the placing table.

[0019] 2. In the present invention, through the setting of the ink feeding assembly, while the rotating member drives the embossing roller to rotate for embossing printing, the printing ink in the ink supply box can be intermittently added, so as to supplement the ink on the sponge block subsequently. And the embossing roller rotates to continuously contact the sponge block, so that the printing ink infiltrated on the sponge block is smeared on the embossing roller. Compared with the existing embossing printing equipment, the present invention continuously smears the ink on the embossing roller. On the one hand, it can effectively solve the problem that the ink printing on the wrapping paper is uneven when the embossing roller embosses and prints the wrapping paper. On the other hand, it can also avoid the phenomenon that the existing printing equipment adds too much printing ink due to the spray-type ink supplement, resulting in waste caused by ink dripping.

[0020] 3. With the provision of the spring and the outer edge plate in the present invention, when the amount of ink in the sponge block is too small, the weight of the sponge block will correspondingly decrease, and the weights exerted on the spring by the placement rack outside the sponge block and the outer edge plate will synchronously decrease. Therefore, under the push of the spring, the outer edge plate slides upward in the through groove. At this time, the outer edge plate drives the placement rack and the sponge block to move upward synchronously. When the placement rack moves upward, it will compress the spiral tube. And when the outer edge plate drives the sponge block to move upward, the ink control member will move upward with the sponge block. When the ink control member moves upward, the upper part of it will cancel the blockage of the connection between the ink receiving box and the spiral tube. At this time, the printing ink reserved in the ink receiving box will flow through the spiral tube into the sponge block, and the sponge block adsorbs the flowing-down ink. When the sponge block adsorbs ink to reach a certain weight, the weights exerted on the spring by the placement rack and the outer edge plate will increase. At this time, the spring will be compressed. At the same time, when the placement rack and the sponge block move downward, the compression of the spiral tube will be cancelled, and at the same time, the ink control member will move downward with the sponge block, and the ink control member will cancel the blockage of the connection between the ink receiving box and the spiral tube.

[0021] 4. With the provision of the cleaning unit in the present invention, on the one hand, it can clean the surface of the wrapping paper before embossing and printing, removing the dust and impurities adhering to the surface of the wrapping paper, and avoiding the influence of the dirt on the surface of the wrapping paper on the effect of embossing and printing. On the other hand, the cleaning unit can also smooth out the omitted wrinkles on the wrapping paper to make it flat and unfolded. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention

[0036] An automatic embossing and printing device for packaging art paper is a printing that applies pressure selectively to materials. Specifically, when continuously embossing and printing packaging art paper, the printing roller rotates to smear printing ink on its surface

[0037] Such as Figures 1 - 10As shown in the figure, it includes a substrate 1. On the side walls of the substrate 1, a unwinding roller 10 and a winding roller 11 are symmetrically installed through electric sliders respectively. Between the winding roller 11 and the unwinding roller 10, there are two symmetrically arranged clamping frames 20. The clamping frames 20 are slidably connected to the substrate 1. In the middle of the clamping frame 20, a rotating member 201 is rotatably installed through a motor. A stamping roller 3 is detachably installed between the two rotating members 201. On the upper part of the clamping frame 20, electric push plates 202 are symmetrically installed. At the top of the electric push plate 202, an ear plate 203 is fixedly installed. A two-way push rod 204 is commonly installed between two corresponding ear plates 203. An installation frame 21 is commonly installed between the two ear plates 203 on one side. A suction cylinder 22 is fixedly installed in the installation frame 21. A ink discharging component is arranged on the suction cylinder 22. Above the stamping roller 3, there is an ink storage tank 23 for storing ink. The two sides of the ink storage tank 23 are fixedly connected to the two-way push rod 204 through connecting pieces. Below the ink storage tank 23, there is an ink receiving box 25 fixedly connected to the connecting piece. On the lower parts of both sides of the ink receiving box 25, through grooves are opened. An outer edge plate 252 is slidably installed in the through groove. A spring is connected between the outer edge plate 252 and the ink receiving box 25. A placing rack 26 is commonly connected between the two outer edge plates 252. A sponge block 261 for smearing ink on the stamping roller 3 is arranged in the placing rack 26. A placing table 205 is commonly connected between the two clamping frames 20 through a telescopic plate. On one side of the substrate 1, there is a cleaning unit connected to the substrate 1.

[0038] By starting the rotation of the electric slider, the winding roller 11 and the unwinding roller 10 respectively perform the winding and unwinding cooperation on the wrapping paper during embossing printing. By the expansion and contraction of the two-way push rod 204, the two clamping frames 20 are moved closer or farther away from each other, so as to disassemble and assemble different stamping rollers 3. Through different pattern settings on different stamping rollers 3, different embossing printing requirements of the wrapping paper can be met. When the motor is started to drive the stamping roller 3 to rotate, the wrapping paper can be embossed on the placing table 205.

[0039] Through the setting of the ink discharging component, while the rotating member 201 drives the stamping roller 3 to rotate for embossing printing, the ink receiving box 25 can be intermittently filled with printing ink for subsequent replenishment of the sponge block 261. And by the rotation of the stamping roller 3, it continuously contacts with the sponge block 261, so that the printing ink infiltrated on the sponge block 261 is smeared on the stamping roller 3. Compared with the existing embossing printing equipment, the present invention continuously smears ink on the stamping roller 3. On the one hand, it can effectively solve the problem of uneven ink printing on the wrapping paper when the stamping roller 3 performs embossing printing on the wrapping paper. On the other hand, it can also avoid the phenomenon that the existing printing equipment adds too much printing ink due to the spray-type ink replenishment, resulting in waste caused by ink dripping.

[0040] When ink replenishment is required in the sponge block 261, due to the arrangement of the spring and the outer edge plate 252, when the ink in the sponge block 261 is too little, the weight of the sponge block 261 will decrease, and the weight applied to the spring by the placement rack 26 outside the sponge block 261 and the outer edge plate 252 will also decrease synchronously. Therefore, under the push of the spring, the outer edge plate 252 slides upward in the through groove. At this time, the outer edge plate 252 drives the placement rack 26 and the sponge block 261 to move upward synchronously. When the placement rack 26 moves upward, it will compress the spiral tube 251. And when the outer edge plate 252 drives the sponge block 261 to move upward, the ink control member 262 will move upward with the sponge block 261. When the ink control member 262 moves upward, the upper part of it will cancel the blockage of the connection between the ink receiving box 25 and the spiral tube 251. At this time, the printing ink reserved in the ink receiving box 25 will flow into the sponge block 261 through the spiral tube 251, and the sponge block 261 adsorbs the flowing-down ink. When the sponge block 261 adsorbs ink to a certain weight, the weight applied to the spring by the placement rack 26 and the outer edge plate 252 will increase. At this time, the spring will be compressed. At the same time, when the placement rack 26 and the sponge block 261 move downward, the compression of the spiral tube 251 will be cancelled. At the same time, the ink control member 262 moves downward with the sponge block 261, and the ink control member 262 will cancel the blockage of the connection between the ink receiving box 25 and the spiral tube 251. Compared with the existing embossing printing device, when replenishing ink, the present invention can automatically replenish ink through the weight of the sponge block 261 without relying on external machinery and manual labor, greatly improving the convenience of ink replenishment;

[0041] Through the setting of the cleaning unit, on the one hand, it can clean the surface of the wrapping paper before embossing printing, removing the dust and impurities adhering to the surface of the wrapping paper, and avoiding the influence of the dirt on the surface of the wrapping paper on the embossing printing effect. On the other hand, the cleaning unit can also smooth out the missed wrinkles on the wrapping paper to make it flat and unfolded.

[0042] The ink discharging assembly includes a side box 24 installed on the side of the ink storage box 23 close to the suction cylinder 22. A runner 221 is fixedly installed on the rotating member 201 on one side. The runner 221 is rotatably installed with a push-pull member 222 on the side far from the rotating member 201. A piston rod 223 is sleeved outside one side of the push-pull member 222. The piston rod 223 penetrates and slides in the suction cylinder 22. A connecting pipe 224 communicating with its inner cavity is fixedly installed on the side of the suction cylinder 22 far from the piston rod 223. One end of the connecting pipe 224 far from the suction cylinder 22 communicates with the inner cavity of the side box 24.

[0043] On one side of the inner cavity of the side box 24, an L-shaped plate 241 is fixedly installed. A moving plate 242 is slidably installed up and down on one side of the armor connecting pipe 224 of the L-shaped plate 241. One side of the upper end surface of the moving plate 242 is adapted to the end of the connecting pipe 224. A spring is jointly connected between the moving plate 242 and the L-shaped plate 241. A vertical groove is provided on the side of the side box 24 close to the suction cylinder 22. A connecting frame 243 fixedly connected to the lower end surface of the moving plate 242 is slidably installed in the vertical groove. A plurality of material discharging openings are formed on the lower end surface of the ink storage box 23. A plurality of rubber plugs 244 for opening and closing the material discharging openings are fixedly installed on the connecting frame 243.

[0044] A spiral pipe 251 is jointly installed between the ink receiving box 25 and the placing rack 26. The spiral pipe 251 is respectively communicated with the ink receiving box 25 above and the placing rack 26 below. The spiral pipe 251 is of a flexible and compressible structure. A ink control member 262 fixedly connected to the top end of the sponge block 261 is provided in the middle of the spiral pipe 251. The upper end of the ink control member 262 seals the connection between the ink receiving box 25 and the spiral pipe 251.

[0045] When the motor is started and the rotating member 201 drives the embossing roller 3 to perform embossing printing on the wrapping paper on the placing table 205, the rotating wheel 221 rotates synchronously to make the pushing and pulling member 222 push and pull the piston rod 223. When the piston rod 223 pushes and pulls, the gas is compressed in the suction cylinder 22. When the piston rod 223 is pushed upward, the gas in the suction cylinder 22 is compressed. At this time, the air pressure impacts the moving plate 242 through the connecting pipe 224. The moving plate 242 drives the connecting frame 243 to move downward under the impact of the air pressure. When the connecting frame 243 moves downward, it synchronously drives a plurality of rubber plugs 244 to move out of the material discharging openings below the ink storage box 23. At this time, the printing ink in the ink storage box 23 drips into the ink receiving box 25 to prepare for the subsequent automatic replenishment of the printing ink. When the piston rod 223 is pulled downward to draw out the gas in the suction cylinder 22, the air pressure cancels the impact on the moving plate 242. At this time, under the action of the spring, the moving plate 242 moves upward. The upper part of the moving plate 242 blocks the end of the connecting pipe 224. While the connecting frame 243 moves upward, it drives the rubber plugs 244 to move into the material discharging openings below the ink storage box 23 and finally blocks them. The printing ink in the ink storage box 23 stops falling.

[0046] The cleaning unit includes two symmetrically arranged smoothing plates 41. A round rod fixedly connected to the substrate 1 is rotatably installed in the middle of the smoothing plates 41. An adhesion roller is detachably installed in the middle of the side of the two smoothing plates 41 close to each other. A driving wheel 42 is provided on the side of the two smoothing plates 41 close to the substrate 1. The driving wheel 42 is rotationally connected to the substrate 1 through a motor. Driving wheels 43 rotationally connected to the substrate 1 are symmetrically arranged above and below the driving wheel 42. The driving wheels 43 are rotationally connected to the substrate 1.

[0047] A long rod is fixedly installed in the middle of the driven wheel 43, and an extrusion wheel 431 is fixedly installed on the long rod. The extrusion wheel 431 is always in contact with its corresponding screed board 41. On one side of each of the two screed boards 41, there is a rectangular plate fixedly connected to the base plate 1, and a spring is commonly connected between the rectangular plate and the screed board 41.

[0048] When the unwinding roller 10 and the winding roller 11 cooperate to unwind and wind, the motor is turned on to drive the driving wheel 42 to rotate. When the driving wheel 42 rotates, it synchronously drives the upper and lower driven wheels 43 to rotate through meshing. When the driven wheel 43 rotates, it drives the extrusion wheel 431 to rotate through the long rod. When the extrusion wheel 431 rotates, it intermittently pushes the screed board 41. At this time, the upper and lower screed boards 41 repeatedly scrape the wrapping paper passing between the upper and lower screed boards 41. Through scraping, the wrinkles generated on the wrapping paper can be flattened and unfolded. And when the upper and lower screed boards 41 scrape the upper and lower surfaces of the wrapping paper, the adhesion rollers on the screed board 41 adhere to and clean the dirt on the wrapping paper. By scraping the wrinkled parts of the wrapping paper and cleaning the surface dirt, the qualified rate of the wrapping paper during embossing printing is effectively improved.

[0049] The round shaft in the middle of the driving wheel 42 penetrates and slides through one end of the base plate 1. A pushing wheel 44 is fixedly installed at the end of the round shaft away from the driving wheel 42. A reciprocating plate 45 slidably connected to the base plate 1 is arranged on one side of the pushing wheel 44. There is a moving groove behind the reciprocating plate 45. The moving groove is opened on the base plate 1, and a compression rod 461 fixedly connected to the reciprocating plate 45 is slidably installed in the moving groove.

[0050] A blower tube 46 fixedly connected to the base plate 1 is arranged on one side of the compression rod 461, and the compression end of the compression rod 461 is compressed inside the cavity of the blower tube 46.

[0051] In the middle of the end of the blower tube 46 away from the compression rod 461, an air duct 462 is fixedly installed. The air duct 462 is communicated with the inner cavity of the blower tube 46. A plurality of air blowing openings are opened on the upper end surface of the placing table 205 near the winding roller 11. The air duct 462 away from the blower tube 46 is respectively communicated with the plurality of air blowing openings.

[0052] A spring is sleeved outside the compression rod 461 and is located inside the blower tube 46. When the driving wheel 42 rotates, it synchronously drives the pushing wheel 44 to rotate. When the pushing wheel 44 rotates, it intermittently squeezes the reciprocating plate 45 to slide left and right. When the reciprocating plate 45 slides left and right, it drives the compression rod 461 to be compressed inside the blower tube 46. The air in the blower tube 46 is supplied to the air blowing openings on the placing table 205 through the air duct 462. The air blown out through the air blowing openings can accelerate the curing of the ink on the wrapping paper. At the same time, it can also blow up the wrapping paper when the winding roller 11 winds the wrapping paper, avoiding the wrapping paper from adhering to the placing table 205 due to hot pressing after embossing printing.

[0053] A one-way valve is provided inside the air outlet. At one end of the unwinding roller 10 and the winding roller 11, there is a resisting member placed on the substrate 1, and a notch for guiding the wrapping paper is provided on the resisting member.

[0054] When the present invention is in use, one end of the wrapping paper on the unwinding roller 10 is pulled, passed through between the two flattening plates 41, and then wound around the winding roller 11. Subsequently, the resisting member is moved on the substrate 1 so that the resisting member resists the ends of the wrapping paper rolls on the winding roller 11 and the unwinding roller 10. At the same time, the notch on the resisting member can guide the wrapping paper during winding and unwinding, preventing the wrapping paper from loosening. The motor is turned on, and the rotating member 201 drives the embossing roller 3 to rotate and contact the sponge block 261 to complete the coating of the ink. At the same time, the embossing roller 3 performs embossing printing on the wrapping paper on the placement table 205. Meanwhile, the rotating wheel 221 rotates synchronously, causing the pushing and pulling member 222 to push and pull the piston rod 223. When the piston rod 223 is pushed and pulled, the gas in the suction cylinder 22 is compressed. When the piston rod 223 is pushed upward, the gas in the suction cylinder 22 is compressed. At this time, the air pressure impacts the moving plate 242 through the connecting pipe 224. Driven by the air pressure, the moving plate 242 drives the connecting frame 243 to move downward. When the connecting frame 243 moves downward, it synchronously drives a plurality of rubber plugs 244 to move out of the material outlet below the ink storage tank 23. At this time, the printing ink in the ink storage tank 23 drips into the ink receiving box 25 to prepare for the automatic replenishment of the printing ink later. When the piston rod 223 is pulled downward to draw out the gas in the suction cylinder 22, the air pressure cancels the impact on the moving plate 242. At this time, under the action of the spring, the moving plate 242 moves upward, and the upper part of the moving plate 242 blocks the end of the connecting pipe 224. While the connecting frame 243 moves upward, it drives the rubber plugs 244 to move into the material outlet below the ink storage tank 23 and finally blocks it, and the printing ink in the ink storage tank 23 stops falling;

[0055] The motor is turned on to drive the driving wheel 42 to rotate. When the driving wheel 42 rotates, it synchronously drives the upper and lower driven wheels 43 to rotate through meshing. When the driven wheels 43 rotate, they drive the pressing wheel 431 to rotate through the long rod. When the pressing wheel 431 rotates, it intermittently pushes the flattening plate 41. At this time, the upper and lower flattening plates 41 repeatedly scrape the wrapping paper passing between the upper and lower flattening plates 41. Through scraping, the wrinkles generated on the wrapping paper can be flattened and unfolded. And when the upper and lower flattening plates 41 scrape the upper and lower surfaces of the wrapping paper, the adhering rollers on the flattening plates 41 adhere to and clean the dirt on the wrapping paper. By scraping the wrinkles on the wrapping paper and cleaning the surface dirt, the qualified rate of the wrapping paper during embossing printing is effectively improved;

[0056] When the driving wheel 42 rotates, it synchronously drives the pushing wheel 44 to rotate. When the pushing wheel 44 rotates, it intermittently squeezes the reciprocating plate 45 to slide left and right. When the reciprocating plate 45 slides left and right, it drives the compression rod 461 to compress inside the air cylinder 46. The air in the air cylinder 46 is supplied to the air outlet on the placing table 205 through the air duct 462. The air blown out through the air outlet can accelerate the curing of the ink on the wrapping paper. At the same time, it can also blow up the wrapping paper when the winding roller 11 winds the wrapping paper, preventing the wrapping paper from adhering to the placing table 205 due to hot pressing after embossing printing.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
