Description

Technical Field

[0001] This invention belongs to the field of packaging box coding technology, specifically a coding machine for edible oil packaging boxes. Background Technology

[0002] A coding machine is an industrial device that achieves non-contact marking through software control. It is widely used in production lines (such as production and packaging lines for edible oil packaging boxes). It is an industrial coding device specifically designed for marking and printing on the surface of packaging boxes (such as cardboard boxes, plastic boxes, etc.) in the edible oil industry. It is an indispensable part of the additive manufacturing equipment manufacturing process in the production line. It is used to print information such as production date, batch number, and barcode. It has core advantages such as high efficiency, clarity, and support for variable data. The core technologies are mainly divided into two categories: continuous inkjet and on-demand inkjet, and various models have been derived from these to adapt to different scenarios. Inkjet printers commonly use water-based and oil-based inks for marking packaging boxes. Water-based inks are environmentally friendly, quick-drying, and have good adhesion, making them suitable for industries with high safety requirements, such as food and pharmaceuticals. They are also suitable for porous materials such as cardboard boxes and corrugated paper. Water-based inks are particularly well-suited for cardboard packaging. When refilling ink cartridges on inkjet printers, most existing inkjet printers require stopping the machine, removing the cartridge, and manually injecting the ink using a syringe. The ink needs to be pre-treated beforehand, such as adding ink in small amounts multiple times (to control the ink volume), thoroughly stirring the ink, and adding the appropriate amount of defoamer (approximately 0.2% of the total ink content). The main drawbacks of manual operation are low efficiency, poor accuracy, difficulty in ensuring consistency, and strong dependence on the operator. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides an inkjet printer for edible oil packaging boxes.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an inkjet printer for edible oil packaging boxes, comprising an inkjet printer body and an ink replenishment unit, wherein the inkjet printer body includes an electronic outer box and two ink cartridges that are snapped onto the inner wall of the electronic outer box. The ink replenishment section includes a ring tube for feeding material. The ring tube is equipped with a second meshing component, which consists of a large and a small spur gear.

The meshing component one consists of two meshing bevel gears, wherein a vertical rod is fixedly connected to the bevel gear in the horizontal position. A square protective cover for protecting the meshing component one is provided on the rotating rod, and the rod body passes through one end of the square protective cover, and the rotating rod and the square protective cover are rotatably connected.

[0007] Preferably, the bottom end of the vertical rod is fixedly connected to the top end of the small spur gear. A special-shaped protective cover for protecting the meshing component two and the gear ring is fixedly connected to the top plate of the circular partition. An L-shaped infusion tube is fixedly connected through the body of the transparent ink tank 201. The vertical rod and the L-shaped infusion tube both pass through the special-shaped protective cover, and the vertical rod and the special-shaped protective cover are rotatably connected. The part of the L-shaped infusion tube near the top end is fixedly connected through to one end of the transparent ink tank. The large spur gear, the small spur gear, and the gear ring are all rotatably connected to the top plate of the circular partition and the inner wall of the special-shaped protective cover.

[0008] Preferably, an elastic telescopic rod is fixedly connected to one end of the outer wall of each baffle, and a long ear plate is fixedly connected to the movable end of the elastic telescopic rod away from the ring tube. The top plate of the long ear plate is fixedly connected to the long rectangular groove opened at the bottom end of the circular partition, and the top plate of the baffle can be slidably connected to the long rectangular groove.

[0009] Preferably, an inclined guide plate is fixedly connected to one side of the bottom plate of the circular partition, and a water turbine rod is rotatably connected to the plate of the inclined guide plate. The two ends of the water turbine rod extend out of the plate of the inclined guide plate 215, and the water turbine rod can rotate around the origin on the inclined guide plate under the drive of external force.

[0010] Preferably, a rocker disc is fixedly connected to both ends of the water turbine rod, and a swing plate is provided on the disc of each of the two rocker discs. A long arc groove is formed through the plate of the swing plate located at the rocker disc, and the remote rod on the rocker disc and the groove of the long arc groove are slidably connected in contact.

[0011] Preferably, a shaft is fixedly connected to the top plate of the swing plate, and a short ear plate 220 is rotatably connected to the swing plate 218 via the shaft. The top plate of the short ear plate is fixedly connected to the long rectangular groove opened at the bottom of the circular partition.

[0012] Preferably, the meshing rotation structure includes a U-shaped frame fixedly connected to the inner wall of the gear ring. A pawl is rotatably connected to the frame of the U-shaped frame. Torsion springs are fixedly connected to the outer surfaces of the upper and lower ends of the pawl and the U-shaped frame. A stop plate is also fixedly connected to the inner wall of the gear ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention employs a motor-driven bevel gear and spur gear meshing transmission structure, which drives the cylindrical block on the large spur gear to move in the opposite direction against the baffle. Combined with the reset function of the elastic telescopic rod, it realizes the automatic opening and closing of the ring tube feed port. The PLC program controls the motor stop time to accurately control the ink replenishment amount. By using the dual ink cartridges alternately in the existing technology, plus the design of the Y-shaped bend supply pipe and valve, ink can be replenished individually for ink cartridges with insufficient ink without stopping the machine, ensuring continuous operation of the inkjet printer and improving the efficiency of the inkjet printing production line for edible oil packaging boxes. The water wheel rod on the inclined guide plate is driven to rotate by the impact force of the ink flowing down. Through the linkage structure between the rocker plate and the swing plate, the swing plate automatically stirs the ink in a metered manner, avoiding the problems of component stratification and uneven concentration caused by the ink standing.

[0015] This invention improves the quality and pass rate of inkjet printing by ensuring uniform ink composition after stirring, resulting in consistent color of printed text / patterns without uneven shades or localized fading. Utilizing the meshing transmission of a large spur gear and a gear ring, combined with a unidirectional rotation structure of a pawl and ratchet disc, it achieves intermittent alignment between the liquid storage tank and the lower liquid tank, automatically and quantitatively dispensing defoamer. Furthermore, the amount of defoamer added precisely matches the amount of ink replenishment (stable at approximately 0.2%, compatible with an error range of ±0.05% to ±0.1%), effectively eliminating air bubbles in the ink. The defoamed ink is sprayed continuously and evenly, avoiding problems such as ink breaks, ink splatter, and blurred edges during coding. At the same time, the structure of the L-shaped infusion tube and the conical block guide groove allows for convenient replenishment of defoamer, making the operation simple.

[0016] This invention integrates three major functions—quantitative feeding, ink stirring, and defoamer addition—through the ink replenishment section. Each component is modularly designed and equipped with square and irregularly shaped protective covers to reduce the corrosion of transmission components by dust and oil, thereby extending the service life of the equipment.

[0019] 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.

[0020] like Figures 1 to 8 As shown, the present invention provides an inkjet printer for edible oil packaging boxes, including an inkjet printer body 1 and an ink replenishment unit 2. The inkjet printer body 1 includes an electronic outer box 101 and two ink cartridges 102 that are snapped onto the inner wall of the electronic outer box 101. The ink replenishment unit 2 includes a ring tube 210 for feeding material. The ring tube 210 is equipped with a meshing component 209, which is composed of a large and a small spur gear. The tube body of the ring tube 210 passes through the central wheel of the large spur gear, and the large spur gear and the ring tube 210 are rotatably connected. Two cylindrical blocks 211 are fixedly connected to the lower surface of the large spur gear. Baffles 212 are slidably connected to the outer surfaces of the two cylindrical blocks 211. The top side plates of the two baffles 212 are slidably connected to the bottom end of the ring tube 210. A drive structure is provided above the small spur gear. The drive structure can drive the two baffles 212 to move in opposite directions at the same time, which is used to automatically control the opening and closing of the two baffles 212 for feeding material. A transparent ink tank 201 is fixedly connected to the outer wall of the electronic outer casing 101. The top of the transparent ink tank 201 is tightly fitted with a lid. A circular partition 202 is fixedly connected to the inner wall of the transparent ink tank 201. A circular groove is opened through the center of the circular partition 202, and a long rectangular groove is also opened on the bottom plate of the circular partition 202. A Y-shaped bent supply pipe 203 is fixedly connected through the bottom of the transparent ink tank 201. The two ends of the Y-shaped bent supply pipe 203 away from the transparent ink tank 201 are respectively fixedly connected through the box body of the two ink cartridges 102. A valve 204 for controlling the flow of liquid is installed on each of the three sections of the Y-shaped bent supply pipe 203. The drive structure includes a motor 205 fixedly connected to the outer wall of the transparent ink tank 201. A rotating rod 206 passing through the body of the transparent ink tank 201 is fixedly connected to the output shaft of the motor 205, and the rod body of the rotating rod 206 is rotatably connected to the body of the transparent ink tank 201. A meshing component 207 is fixedly connected to the rotating rod 206 away from the rod body of the motor 205. The meshing component 207 consists of two meshing bevel gears. A vertical rod is fixedly connected to the bevel gear in the horizontal position. A square protective cover 208 is provided on the rotating rod 206 to protect the meshing component 207, and the rod body of the rotating rod 206 passes through one end of the square protective cover 208. The rotating rod 206 and the square protective cover 208 are rotatably connected. The bottom end of the vertical rod is fixedly connected to the top end of the small spur gear in the meshing component 209. The large spur gear in the meshing component 209... A gear ring 221 is also meshed on the wheel. A special-shaped protective cover for protecting the meshing component 209 and the gear ring 221 is fixedly connected to the top plate of the circular partition 202. An L-shaped infusion tube 231 is fixedly connected through the body of the transparent ink tank 201. The vertical rod and the rod of the L-shaped infusion tube 231 pass through the special-shaped protective cover, and the vertical rod and the special-shaped protective cover are rotatably connected. The large spur gear, the small spur gear, and the gear ring 221 are all in close contact with the top plate of the circular partition 202 and the inner wall of the special-shaped protective cover. An elastic telescopic rod 213 is fixedly connected to the outer wall of one end of each baffle 212. A long ear plate 214 is fixedly connected to the movable end of the elastic telescopic rod 213 away from the ring tube 210. The top plate of the long ear plate 214 is fixedly connected to the long rectangular groove opened at the bottom of the circular partition 202, and the top plate of the baffle 212 can be in close contact with the long rectangular groove.

[0021] The above solution involves the alternating use of two ink cartridges 102 installed in the electronic outer casing 101. When the ink in one ink cartridge 102 is depleted, the electronic outer casing 101 will display a prompt (the prompt from the electronic outer casing 101 is an automated linkage process of "ink level detection, signal transmission, main control judgment, light triggering plus ink cartridge 102 switching, and continuous prompting / alarm," which is achieved by relying on the ink level detection module, main control circuit board, and indicator light module of the inkjet printer body 1 in conjunction with the dual ink cartridge switching mechanism). This is an existing structure, allowing staff to understand which ink cartridge 102 needs refilling. This is existing technology, and the working principle will not be elaborated further here. When refilling the ink cartridge 102 that has run out of ink, as follows... Figure 2 and Figure 3 As shown, the starting motor 205 drives the rotating rod 206 to rotate. The rotation of the rotating rod 206 drives the two bevel gears in the first meshing assembly 207 to rotate in mutual transmission. This causes the bevel gear in the horizontal position to drive the vertical rod to rotate around its origin within the irregular protective cover, thereby driving the large and small spur gears in the second meshing assembly 209 to rotate in mutual transmission. Figure 5 As shown, the rotation of the large spur gear will inevitably cause the two cylindrical blocks 211 fixed at the bottom to rotate. During this passive rotation, the two cylindrical blocks 211 will slide and contact the two baffles 212 respectively. The two baffles 212, under stress, will translate along opposite paths. The long rectangular groove on the bottom plate of the circular partition 202 provides space for the two baffles 212 to move during their translational opening and closing. Furthermore, the movement of the baffles 212 will compress the elastic telescopic rod 213, causing it to deform and contract under stress on the long ear plate 214. The elastic telescopic rod 213 is also composed of a telescopic rod and a spring, common in existing technologies, and is designed to accommodate the situation where the baffles 212 are not under stress (cylindrical). When block 211 is passively rotated 90 degrees in the opposite direction to reset, it drives baffle 212 to automatically perform elastic reset. When cylindrical block 211 is passively rotated 90 degrees, the two baffles 212 will completely disengage from the bottom end of the ring tube 210, thus failing to seal the bottom of the ring tube 210. This allows the ink in the transparent ink tank 201 to fall naturally into the bottom of the transparent ink tank 201 divided by the circular partition 202. The programming program pre-calculated and set by the PLC system can make the output shaft of motor 205 stop rotating for a specific number of seconds after cylindrical block 211 is passively rotated 90 degrees, thereby controlling the amount of ink dispensed (the amount of ink required to be stored in ink cartridge 102).

[0022] An inclined guide plate 215 is fixedly connected to one side of the bottom plate of the circular partition 202. A water turbine rod 216 is rotatably connected to the inclined guide plate 215, and both ends of the water turbine rod 216 extend out of the inclined guide plate 215. The water turbine rod 216 can rotate around the inclined guide plate 215 under external force. A rocker disc 217 is fixedly connected to both ends of the water turbine rod 216. Each rocker disc 217 is equipped with a swing plate 218. 8 is composed of a plate and a stirring head fixedly connected to the bottom of the plate. The swing plate 218 is located at the rocker plate 217 and has a long arc groove 219 through it. The remote rod on the rocker plate 217 and the groove of the long arc groove 219 are in close contact and slidingly connected. A shaft is fixedly connected to the top plate of the swing plate 218. The swing plate 218 is rotatably connected to a short ear plate 220 through the shaft. The top plate of the short ear plate 220 is fixedly connected to the long rectangular groove opened at the bottom of the circular partition 202.

[0023] The above solution is adopted: such as Figure 4 , Figure 5 and Figure 6 As shown, the flowing ink, guided by the inclined guide plate 215, directly impacts the water wheel rod 216, contacting the wheel plate on the water wheel rod 216 installed in the inclined guide plate 215. This causes the water wheel rod 216 to rotate around its origin on the inclined guide plate 215 under the influence of the liquid. Simultaneously, the rotating water wheel rod 216 drives the rocker discs 217 fixed at both ends to rotate. The rocker arms on the rocker discs 217 then slide within the long arc groove 219 in the swing plate 218, causing... The oscillating plate 218 reciprocates on the short ear plate 220 with the shaft as the axis. Thus, the oscillating plate 218 and the stirring head can stir a certain amount of ink, which can quickly disperse the settled pigment particles and mix the layered solvents. This ensures that the ink added to the ink cartridge 102 each time is in a homogeneous and standardized state, avoiding ink breaks, blurry characters, and missing dots caused by uneven ink. In addition, the homogeneous ink after stirring is free of pigment clumps, which can effectively prevent clump particles from entering the ink path and clogging the precision coding nozzles.

[0024] The toothed ring 221 has a conical block 229 inside. Three guide grooves 230 for guiding the defoamer are opened on the outer wall of the conical block 229. The L-shaped liquid delivery pipe 231 for replenishing the material is located directly above the conical block 229. A meshing rotation structure is provided directly below the conical block 229 for quantitatively dispensing the defoamer to eliminate air bubbles in the ink. The meshing rotation structure includes a U-shaped frame 222 fixedly connected to the inner wall of the toothed ring 221. A pawl 223 is rotatably connected to the frame of the U-shaped frame 222. Torsion springs 224 are fixedly connected to the outer surfaces of the upper and lower ends of the pawl 223 and the U-shaped frame 222. A stop plate 225 is also fixedly connected to the inner wall of the toothed ring 221. The stop plate 225 and the pawl 223 can be intermittently engaged. A ratchet disc 226 is slidably connected to the pawl 223. The pawl 223 and the ratchet disc 226 can also be engaged. The ratchet disc 226 is rotatably connected to the top plate of the circular partition 202. Three liquid storage tanks 227 are opened through the ratchet disc 226. A lower liquid tank 228 is opened through the circular partition 202. The three liquid storage tanks 227 can be intermittently aligned with the lower liquid tank 228.

[0025] The above solution is adopted: such as Figure 3 , Figure 7 and Figure 8As shown, during the passive rotation of the large spur gear in the meshing assembly 209, it synchronously drives the gear ring 221 connected to it to rotate. The rotation of the gear ring 221 will inevitably drive the pawl 223 connected by the U-shaped frame 222 to rotate as well. At that time, the pawl 223 will abut against the abutment plate 225, thereby engaging with the ratchet disc 226. Under the force, the ratchet disc 226 will rotate. During the rotation, the multiple liquid storage grooves 227 opened on the ratchet disc 226 will cause one of the storage grooves to be filled. The liquid reservoir 227 and the lower liquid channel 228 on the circular partition 202 are aligned, so the defoamer stored in the liquid reservoir 227 flows directly down into the transparent ink tank 201 through the lower liquid channel 228, mixing with the metered ink in the tank (the defoamer content is 0.2% of the metered ink). The defoamer can quickly destroy existing bubbles and inhibit the generation of new bubbles, ensuring continuous and uniform ink ejection, and clear edges and consistent color of printed patterns and text. When the large spur gear rotates in the reverse direction to reset, At this moment, the indirectly passively rotating pawl 223 will not contact the abutment plate 225. Therefore, the pawl 223 will slide against the outer surface of the ratchet disc 226. Simultaneously, the sliding motion of the pawl 223 on the outer surface of the ratchet disc 226 will drive the torsion spring 224, which is fixedly mounted between the torsion spring and the U-shaped bracket 222. Therefore, during the rotational reset of the large spur gear in the meshing assembly 209, the gear ring 221 will not rotate in the opposite direction to reset, but will remain in its current state. The presence of the torsion spring 224 ensures that the pawl 223 does not... Under stress, it can always engage with the ratchet disc 226. Later, when all the defoamer stored in the liquid storage tanks 227 is used up, the defoamer can be manually injected into the tube body by holding a syringe containing defoamer and aiming it at the L-shaped infusion tube 231. The defoamer flows down to the conical block 229 and is guided into the corresponding liquid storage tank 227 through the three guide grooves 230 on the conical block 229. The ink can be replenished by opening the cap on the transparent ink tank 201. The whole replenishment process is convenient and quick.

[0026] It is worth noting that a filter screen is fixedly connected to the top end of the Y-shaped bend supply tube 203. This filter screen is used to prevent the mixing of the quantitative ink and defoamer from causing additional slight bubbles due to the collision of liquids generated during the mixing process and the feeding process. The installed filter screen can effectively filter out bubbles.

[0027] It should be added that: since the transparent ink tank 201 is made of transparent material, after the ink required for replenishment is processed and the motor 205 stops operating, it is necessary to manually rotate and open the two valves 204 on the Y-shaped bend supply pipe 203 (the pipe valves 204 connecting the transparent ink tank 201 and the ink cartridge 102) to achieve automatic flow-guided ink replenishment. Since the ink for replenishment is dispensed at fixed times and in fixed quantities, the defoamer stored in the liquid storage tank 227 is also of a corresponding content (0.2%). In the actual application of the existing technology, the required amount of this defoamer can have a certain numerical deviation. For conventional water-based inks, the effective error range of 0.2% (mass fraction) of defoamer addition is usually ±0.05% to ±0.1%, that is, when the actual addition amount is between 0.1% and 0.3%, a stable defoaming effect can still be maintained.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
