Description

Technical Field

[0001] This invention belongs to the field of printing technology, specifically a printing device for spinning paper tubes. Background Technology

[0002] Paper tubes are tubular objects made from paper, mostly spiral or seamless. They are used in various industries for diverse purposes. In the chemical fiber industry, they are often used to make nylon tubes, spandex tubes, and spandex-coated yarn tubes; in the film industry, they are used for agricultural mulch film, cling film, stretch film, plastic bag tubes (for supermarkets), aluminized film, and electrical capacitor film; in the metallurgical industry, they are commonly used for aluminum plates, steel plates, and iron plates in rolls; in the packaging industry, they are commonly used for outer packaging of medical devices, calligraphy and paintings, food cans, and temperature measuring paper tubes; in the printing industry, they are commonly used for roll printing, film printing, and paper printing; and in the papermaking industry, they are commonly used for newsprint, yarn tube paper, whiteboard paper, fax paper, bill paper, cork paper, aluminum foil paper, writing paper, colored parchment paper, cup paper, and Tetra Pak cling film.

[0003] Currently, printing on spinning paper tubes is often done using a roller brush. The spinning paper tube is fixed, and the printing roller contacts it. Rotating the printing roller transfers the ink onto the spinning paper tube. However, when printing different colors onto the spinning paper tube, if different colors are applied to the printing roller, the ink diffusion will cause uneven distribution on the roller, resulting in uneven printing on the spinning paper tube. Therefore, a spinning paper tube processing and printing device is proposed to solve the problems mentioned in the background art. Summary of the Invention

[0007] Preferably, the two sides of the inner cavity of the movable plate are movably connected to limit crossbars, the outer surface of the limit crossbars is sleeved with a second elastic spring, and the front end of the movable plate is fixedly connected to a handle block.

[0008] Preferably, the top and bottom of the first elastic spring are fixedly connected to the first elastic spring and the piston rod, respectively, and the top and bottom of the outer surface of the piston rod are movably connected to the top and bottom of the inner cavity of the pigment storage tank, respectively.

[0009] Preferably, the bend at one end of the connecting pipe is located in the inner cavity of the support plate and is fixedly connected to the support plate, and the inner cavity at the lower end of the connecting pipe is movably connected to the outer surface of the connecting shaft, and the connecting pipe is a rigid pipe.

[0010] Preferably, the outer surface of the porous roller is provided with circular holes at equal intervals, the bottom of the inner cavity of the connecting block is provided with circular holes, and the porous roller is movably connected to the inner cavities on both sides of the arc-shaped baffle.

[0011] Preferably, the inner cavity of the support plate is movably connected to the outer surface of the connecting shaft, the inner cavity of the printing roller is fixedly connected to the outer surface of the connecting shaft, the end of the connecting shaft away from the power motor is movably connected to the inner cavity of the middle of the support rod, the middle of the outer surface of the limiting rod is movably connected to the inner cavity of the top of the support rod, and one end of the top of the limiting rod is fixedly connected to the bottom of the top rod away from the power motor.

[0012] Preferably, the first gear and the second gear are meshed together, the inner cavity of the mating shaft is in the shape of a cross spline, the side of the support shaft near the mating shaft is in the shape of a cross groove, and the inner cavity of the mating shaft is engaged with the support shaft.

[0013] Preferably, the end of the annular spring sheet away from the mating shaft is fixedly connected to the inner cavity of the second gear, and the diameter of the support shaft on the side closer to the second gear is larger than the diameter of the support shaft on the side away from the second gear.

[0014] Preferably, the front and rear ends of the limiting crossbar are fixedly connected to the support base, the front and rear ends of the limiting crossbar are fixedly connected to the support base and the movable plate respectively, and the front end of the limiting crossbar passes through the front end of the support base and is movably connected to the inner cavity of the front end of the support base.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention enables the device to print various pigments onto spinning paper tubes through the cooperation of structures such as support plates, printing rollers, piston rods, and connecting pipes. A motor rotates the connecting shaft, which in turn rotates the support plates and cams. Simultaneously, a limiting rod drives the top rod and piston rod to move intermittently up and down. When the piston rod moves upward, pigment from the pigment storage tank enters the connecting block through the connecting pipe, then enters the cavity of the perforated roller, and flows through the holes on the roller to diffuse onto the printing roller. At the same time, pigment from inside the connecting block flows through the holes at the bottom of the connecting block and diffuses into the printing roller. Combined with the rotation of the printing roller, the pigment is printed onto the paper tube. Because the device has multiple support plates and printing rollers, it can store different types of pigments, thus achieving the effect of printing multiple colors onto spinning paper tubes.

[0017] This invention utilizes the cooperation between a first gear, a second gear, a mating shaft, and a support shaft to enable the device to print the pigment color on the spinning paper tube in a spiral shape. The rotation of the connecting shaft simultaneously drives the first gear to rotate. The cooperation between the first and second gears causes the second gear to rotate. Simultaneously, the rotation of the second gear drives the mating shaft and the annular spring plate to rotate, which in turn causes the support shaft to rotate. Combined with the action of the cylindrical support block, this causes the support shaft to move away from the power motor, thus creating a spiral pattern on the pigment printed on the spinning paper tube.

[0018] This invention utilizes the cooperation between the movable plate, the second elastic spring, and the handle block to facilitate the disassembly and installation of the spinning paper tube. By pulling the handle block outward, the limiting crossbar causes the movable plate, the cylindrical support block, the support sleeve block, and the support shaft to move forward. The operator then places the spinning paper tube onto the outer surface of the support shaft from the side furthest from the motor. Releasing the handle block causes the movable plate, the cylindrical support block, the support sleeve block, and the support shaft to reset due to the elasticity of the second elastic spring, thereby resetting the spinning paper tube. At this point, the spinning paper tube will contact the outer surface of the printing roller. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 11As shown, the present invention provides a spinning paper tube processing and printing device, including a support base 1 and a movable plate 19. A support frame 2 is fixedly connected to the rear end of the top of the support base 1. Pigment storage tanks 3 are fixedly connected at equal intervals to the inner cavity of the top of the support frame 2. Support plates 8 are fixedly connected at equal intervals to the front end of the support frame 2. A printing roller 9 is movably connected and snapped into the inner cavity of one side of the support plate 8. A piston rod 4 is movably connected to the inner cavity of the pigment storage tank 3. A first elastic spring 5 is sleeved on the outer surface of the piston rod 4. A top rod 11 is fixedly connected to the top of the piston rod 4. A connecting pipe 12 is fixedly connected to the inner cavity of the bottom of the pigment storage tank 3. A power motor 6 is fixedly connected to one side of the top of the support base 1. A connecting shaft 7 is fixedly connected to the output shaft end of the power motor 6. A cam 10 is fixedly connected to the end of the connecting shaft 7 away from the power motor 6. A limiting rod 16 is movably connected to the inner cavity of the cam 10. A support frame rod 15 is fixedly connected to the end of the top of the support base 1 away from the power motor 6. A connecting block 13 is fixedly connected to the bottom end of the connecting pipe 12. The connecting block 13 has a curved baffle 17 and a perforated roller 14 movably connected to both sides of its outer surface. The connecting shaft 7 has a misaligned structure 18 fixedly connected to the side of its outer surface near the power motor 6. The connecting shaft 7 is rotated by the operation of the power motor 6, which in turn drives the support plate 8 and the cam 10 to rotate. At this time, the limiting rod 16 will drive the top rod 11 and the piston rod 4 to move up and down intermittently. When the piston rod 4 moves upward, the pigment inside the pigment storage tank 3 will enter the interior of the connecting block 13 through the connecting pipe 12, and then enter the cavity of the perforated roller 14. It will then leave through the round hole on the perforated roller 14 and diffuse onto the printing roller 9. At the same time, the pigment inside the connecting block 13 will leave through the round hole at the bottom of the connecting block 13 and diffuse into the interior of the printing roller 9. With the rotation of the printing roller 9, the pigment will be printed on the paper tube. Since the device is equipped with multiple support plates 8 and printing rollers 9, different types of pigments can be stored, thereby achieving the effect of printing multiple colors on the spinning paper tube.

[0033] It is worth noting that the design of the piston rod 4 serves to intermittently block the flow of pigment from the inside of the pigment storage tank 3 to the inside of the connecting pipe 12, thereby preventing excessive pigment from being transported into the pigment storage tank 3 and resulting in waste.

[0034] like Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10As shown, the misaligned structure 18 includes a first gear 181, the inner cavity of which is fixedly connected to the outer surface of the connecting shaft 7. Support sleeves 187 and cylindrical support blocks 186 are fixedly connected to both sides of the top of the movable plate 19, respectively. A second gear 182 is movably engaged in the inner cavity of the top of the support sleeve 187. A mating shaft 183 is movably connected to the inner cavity of the second gear 182. Annular spring plates 184 are fixedly connected to both ends of the outer surface of the mating shaft 183. A support shaft 185 is threadedly connected to the inner cavity of the cylindrical support block 186. Through the connection... As shaft 7 rotates, it also drives the first gear 181 to rotate. At this time, through the cooperation between the first gear 181 and the second gear 182, the second gear 182 rotates. While the second gear 182 rotates, it will drive the mating shaft 183 and the annular spring plate 184 to rotate, which in turn causes the support shaft 185 to rotate. At the same time, with the action of the cylindrical support block 186, the support shaft 185 will move away from the power motor 6, so that the ink printed on the spinning paper tube is spiral.

[0035] like Figure 1 , Figure 8 , Figure 11 As shown, limit crossbars 20 are movably connected to both sides of the inner cavity of the movable plate 19. A second elastic spring 21 is sleeved on the outer surface of the limit crossbar 20. A handle block 22 is fixedly connected to the front end of the movable plate 19. The front and rear ends of the limit crossbar 20 are fixedly connected to the support base 1. The front and rear ends of the limit crossbar 20 are fixedly connected to the support base 1 and the movable plate 19, respectively. The front end of the limit crossbar 20 passes through the front end of the support base 1 and is movably connected to the inner cavity of the front end of the support base 1. Limit crossbars 20 are movably connected to both sides of the inner cavity of the movable plate 19. A second elastic spring 21 is sleeved on the outer surface of the limit crossbar 20. A handle block 22 is fixedly connected to the front end of the movable plate 19. The top and bottom of the first elastic spring 5 are fixed to the first elastic spring 5 and the piston rod 4, respectively. The piston rod 4 is connected to the top and bottom of the outer surface of the pigment storage tank 3. By pulling the handle block 22 to the outward side, the limiting crossbar 20 causes the movable plate 19, cylindrical support block 186, support sleeve block 187 and support shaft 185 to move to the forward side. Then the operator puts the spinning paper tube from the side of the power motor 6 onto the outer surface of the support shaft 185 and then releases the handle block 22. At this time, the second spring spring 21 will cause the movable plate 19, cylindrical support block 186, support sleeve block 187 and support shaft 185 to reset, thereby causing the spinning paper tube to reset. At this time, the spinning paper tube will contact the outer surface of the printing roller 9.

[0036] like Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 As shown, the first gear 181 and the second gear 182 are meshed together. The inner cavity of the mating shaft 183 is cross-spline shaped. The support shaft 185 has a cross-groove shaped side near the mating shaft 183. The inner cavity of the mating shaft 183 is engaged with the support shaft 185. The end of the annular spring plate 184 away from the mating shaft 183 is fixedly connected to the inner cavity of the second gear 182. The diameter of the support shaft 185 near the second gear 182 is larger than the diameter of the side away from the second gear 182. Through the design of the cross-groove on the support shaft 185 and the cross-spline engagement inside the mating shaft 183, when the first gear 181 rotates, driving the second gear 182 and the support shaft 185 to rotate, it prevents the mating shaft 183 from preventing the support shaft 185 from moving away from the power motor 6.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the bend at one end of the connecting pipe 12 is located in the inner cavity of the support plate 8 and is fixedly connected to the support plate 8. The inner cavity at the lower end of the connecting pipe 12 is movably connected to the outer surface of the connecting shaft 7. The connecting pipe 12 is a rigid pipe. The outer surface of the perforated roller 14 has equally spaced circular holes. The bottom of the inner cavity of the connecting block 13 has a circular hole. The perforated roller 14 is movably connected to the inner cavities on both sides of the arc-shaped baffle 17. The inner cavity of the support plate 8 is movably connected to the outer surface of the connecting shaft 7. The inner cavity of the printing roller 9 is fixedly connected to the outer surface of the connecting shaft 7. The end of the connecting shaft 7 away from the power motor 6 is movably connected to the inner cavity in the middle of the support frame rod 15. The outer surface of the limiting rod 16... The middle part is movably connected to the inner cavity of the top of the support rod 15, and one end of the top of the limiting rod 16 is fixedly connected to the bottom of the top rod 11 away from the power motor 6. Through the design of the arc-shaped baffle 17, the pigment inside the porous roller 14 is prevented from being thrown out due to centrifugal force when it rotates, thus ensuring that the pigment inside the porous roller 14 flows out downward. At the same time, since the porous roller 14 is located below the inner cavity of the printing roller 9, and the support shaft 185 is located in front of the printing roller 9, the pigment flows out of the porous roller 14 and diffuses into the inside of the printing roller 9, and then further diffuses due to the rotation of the printing roller 9, so as to facilitate the subsequent printing of the printing roller 9.

[0038] Working principle and usage process of this invention:

[0039] First, the operator pulls the handle block 22 to the outer side. At this time, due to the limiting action of the limiting crossbar 20, the movable plate 19, the cylindrical support block 186, the support sleeve block 187 and the support shaft 185 are moved to the front side. Then, the operator puts the spinning paper tube on the outer surface of the support shaft 185 from the side of the power motor 6. Then, the operator releases the handle block 22. At this time, due to the elastic force of the second spring 21, the movable plate 19, the cylindrical support block 186, the support sleeve block 187 and the support shaft 185 will be reset, thereby driving the spinning paper tube to reset. At this time, the spinning paper tube will contact the outer surface of the printing roller 9.

[0040] Subsequently, the power motor 6 is operated, causing the connecting shaft 7 to rotate, which in turn drives the support plate 8 and the cam 10 to rotate. At this time, due to the limiting effect of the support rod 15 on the limiting rod 16, and in conjunction with the action of the cam 10, the limiting rod 16 will drive the top rod 11 and the piston rod 4 to move up and down intermittently. When the piston rod 4 moves upward, the pigment inside the pigment storage tank 3 will enter the interior of the connecting block 13 through the connecting pipe 12, and then enter the inner cavity of the perforated roller 14, and leave from the round holes on the perforated roller 14 and diffuse onto the printing roller 9. At the same time, the pigment inside the connecting block 13 will leave from the round holes at the bottom of the connecting block 13 and diffuse into the interior of the printing roller 9. With the rotation of the printing roller 9, the pigment will be printed on the paper tube.

[0041] While the connecting shaft 7 rotates, it also drives the first gear 181 to rotate. At this time, through the cooperation between the first gear 181 and the second gear 182, the second gear 182 rotates. While the second gear 182 rotates, it drives the mating shaft 183 and the annular spring plate 184 to rotate, which in turn causes the support shaft 185 to rotate. At the same time, with the action of the cylindrical support block 186, the support shaft 185 will move away from the power motor 6, so that the ink printed on the spinning paper tube is spiral, thus completing the operation.
