Description

Technical Field

[0001] The invention relates to the technical field of inkjet printers, and in particular to a fully automatic rotary disc type circular digital inkjet printer. Background Art

[0002] Traditional cup inkjet printing equipment mostly relies on mechanical clamps to fix the cups. However, the use of clamps may not only cause instability during the fixing process, but also may cause the cup to shift when fixed or even damage the surface of the cup due to excessive or uneven pressure on the cup by the clamp. Especially when dealing with fragile or easily damaged cups, traditional mechanical clamps are prone to cause physical damage such as scratches, cracks or dents to the cups. On the other hand, in traditional equipment, once printing is completed, the process of releasing the fixation usually requires more complex mechanical devices. Although the cup is stable when fixed, after printing is completed, the process of releasing the fixation by the automated system is cumbersome and inefficient, which seriously affects production efficiency. Summary of the invention

[0003] The object of the present invention is to provide a fully automatic rotary disc circular digital inkjet printing machine, which improves the production efficiency and stability of the equipment through airbag fixation and automatic resetting.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a fully automatic rotary disc type circular digital inkjet printer, comprising a shell, a rotatable disc is installed on a support column arranged on the bottom wall of the inner cavity of the shell, a roller is installed on the output end of a plurality of rotating motors fixed on the top of the disc, a first air chamber formed between the inner cavity wall of the roller and the partition plate is connected with a plurality of air bags sleeved on the outer ring of the roller, the first air chamber is connected with the inner cavity of the roller through a pipeline, a piston is fixed on the other end of a reset spring fixed in the inner cavity of the roller, a push rod penetrating the roller is fixed on the piston, a support member connected with an inflator through a pipeline is sleeved on the outer ring of the roller, and the roller is connected with the inner cavity of the support member through a plurality of circular holes arranged on the outer ring; The guide air boxes on both sides of the support column are respectively connected to a cooling box and a drying box. The bottom of the ink supplier installed on the top of the inner cavity of the shell is provided with a plurality of inkjet heads and a cooling nozzle connected to the left guide air box. A plurality of drying nozzles connected to the right guide air box are arranged on the surface of the disc. A driving motor for driving the disc to rotate is provided in the support column, which can synchronously drive the fan blades in the guide air box to operate through a plurality of bevel gears.

[0005] As a further description of the above technical solution: a discharge hole and a feed hole are provided on the surface of the shell, a material guide trough is installed at the discharge hole, and a material conveyor is provided at the feed hole.

[0006] As a further description of the above technical solution: the inflator is fixedly connected to the top of the rotating motor, and the support is fixedly connected to the top of the disc.

[0007] As a further description of the above technical solution: the cooling box and the drying box are both installed in the inner cavity of the shell, the ink supplier is connected to the inkjet head through a pipeline, and the inkjet head is a digital inkjet head.

[0008] As a further description of the above technical solution: a telescopic rod is fixed to the output end of the driving motor, a convex column is provided at the bottom of the disc which penetrates into the inner cavity of the supporting column and is rotatably connected to the supporting column, and the telescopic end of the telescopic rod penetrates into the inner cavity of the convex column and is clamped therewith.

[0009] As a further description of the above technical solution: the output end of the driving motor is sleeved with a main bevel gear, and auxiliary bevel gears are meshed on both sides of the main bevel gear. The auxiliary bevel gear is fixed with a rotating rod that passes through the support column and the guide air box, and the rotating rod is fixed with a guide fan blade.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The compressed gas is delivered to the inside of the support by the inflator, so that the cup is quickly and stably fixed. The gas enters the inner cavity of the drum through the circular hole and pushes the piston to compress the return spring. Then the gas between the piston and the drum is delivered to the first air chamber through the pipeline, and finally the gas is delivered to the airbag, so that the airbag expands and contacts closely with the inner wall of the cup. This process enables the cup to be firmly fixed on the drum, thereby preventing the cup from loosening or position deviation during the inkjet printing process. The way the airbag expands and contacts the inner wall of the cup is softer than that of the traditional clamp, which effectively avoids the damage to the surface of the cup caused by the traditional mechanical clamp, especially when handling fragile cups or cups with easily damaged surfaces, which can reduce the probability of damage.

[0011] 2. After the cup is printed, the compressed gas inside the support is discharged, and the components are quickly reset. By controlling the inflation and deflation process, the airbag contracts and releases the fixing force on the cup. The reset spring and piston drive the ejector rod to eject the printed cup. This design realizes the rapid release of the cup and ensures the efficient operation of the equipment. Through the automated deflation and reset process, the cup can be quickly released and the intervention of manual operation can be reduced, thereby speeding up the turnover of the entire production line and further improving work efficiency. The rapid and smooth ejection of the cup reduces the burden on the operator, avoids the situation where the cup is stuck or difficult to release, makes the operation smoother, and reduces the failure rate of the equipment.

[0012] 3. The present invention realizes multiple drives through a driving motor. On the one hand, the driving motor can drive the disc to rotate, so that the drum and the cup rotate together for inkjet printing. On the other hand, the driving motor also drives the fan blades in the bellows through the bevel gear to send the cold air generated by the cooling box and the hot air generated by the drying box to the cooling nozzle and the drying nozzle. The driving motor can complete the operation of two different functions at the same time, avoiding the need for multiple driving motors, reducing additional driving devices and mechanical components, and making the equipment more concise and efficient.

[0015] 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 creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-Figure 10 The present invention provides a technical solution: a fully automatic rotary disk type circular digital inkjet printer, comprising a shell 10, a rotatable disk 12 is installed on a support column 11 arranged on the bottom wall of the inner cavity of the shell 10, a roller 21 is installed at the output end of a plurality of rotating motors 20 fixed on the top of the disc 12, a first air chamber formed between the inner cavity wall of the roller 21 and a partition plate 211 is communicated with a plurality of air bags 22 sleeved on the outer ring of the roller 21, the first air chamber is communicated with the inner cavity of the roller 21 through a pipeline, a piston 24 is fixed on the other end of a reset spring 23 fixed in the inner cavity of the roller 21, a push rod 25 penetrating the roller 21 is fixed on the piston 24, a support member 27 connected with an inflator 26 through a pipeline is sleeved on the outer ring of the roller 21, and the roller 21 is communicated with the inner cavity of the support member 27 through a plurality of circular holes arranged on the outer ring.

[0017] refer to Figure 5 and Fig.10 In the initial state, the airbag 22 is in an uninflated state. When the drum 21 is inserted into the cup, compressed gas is transported to the inner cavity of the support member 27 through the inflator 26. The gas enters the inner cavity of the drum 21 through the circular hole, and then pushes the piston 24 to compress the return spring 23. The gas between the piston 24 and the drum 21 is transported to the first air chamber through the pipeline, and then the gas in the first air chamber is transported to the airbag 22, so that the airbag 22 expands in the cup and contacts the inner wall of the cup. The expanded airbag 22 is used to fix the cup. At this time, the rotating motor 20 can drive the drum 21 to rotate, thereby driving the cup to rotate.

[0018] This process enables the cup to be firmly fixed on the roller 21, thereby preventing the cup from loosening or position deviation during the inkjet printing process. The way in which the airbag 22 expands and contacts the inner wall of the cup is softer than that of traditional clamps, effectively avoiding damage to the surface of the cup caused by traditional mechanical clamps, especially when handling fragile cups or cups with easily damaged surfaces, which can reduce the probability of damage.

[0019] The inflator 26 is used to suck out the compressed gas inside the support member 27, and the return spring 23 drives the piston 24 to return to its original position. The gas in the airbag 22 enters the first air chamber, and the gas in the first air chamber returns to between the piston 24 and the inner wall of the drum 21. The airbag 22 contracts, and each component is restored to its initial state. At this time, the compressed gas inside the support member 27 continues to be discharged, and the return spring 23 drives the push rod 25 to push out the drum 21 and contact the inner wall of the cup, thereby allowing the push rod 25 to push out the cup. After the cup is pushed out, air is inflated into the support member 27 to restore each component to its initial state.

[0020] This design achieves the rapid release of the cup and ensures the efficient operation of the equipment. Through the automated deflation and reset process, the cup can be quickly released and manual intervention can be reduced, thereby speeding up the turnover of the entire production line and further improving work efficiency. The rapid and smooth ejection of the cup reduces the burden on the operator and avoids the cup getting stuck or difficult to release, making the operation smoother and reducing the failure rate of the equipment.

[0021] The guide air boxes 30 on both sides of the support column 11 are respectively connected to the cooling box 13 and the drying box 14. The cooling box 13 can generate cold air, and the drying box 14 can generate hot air. An ink supplier 15 is installed on the top of the inner cavity of the shell 10. The bottom of the ink supplier 15 is provided with a plurality of inkjet heads 16 and a cooling nozzle 17 connected to the left guide air box 30. The ink supplier 15 is responsible for providing the required ink to the inkjet head 16 and ensuring a stable supply of ink. The ink supplier 15 includes components such as an ink tank, a pipe, a filter and a pump to ensure a stable flow of ink and avoid printing quality problems caused by unstable ink supply. A plurality of drying nozzles 18 connected to the right guide air box 30 are arranged on the surface of the disc 12. A driving motor 19 for driving the disc 12 to rotate is arranged in the support column 11, which can synchronously drive the fan blades in the guide air box 30 to operate through a plurality of bevel gears.

[0022] Multiple drives can be achieved through the drive motor 19. On the one hand, the drive motor 19 can drive the disc 12 to rotate, so that the roller 21 and the cup rotate together for inkjet printing. On the other hand, the drive motor 19 also drives the fan blades in the guide bellows 30 through the bevel gear to send the cold air generated by the cooling box 13 and the hot air generated by the drying box 14 to the cooling nozzle 17 and the drying nozzle 18. The drive motor 19 can perform two different functions at the same time, avoiding the need for multiple drive motors 19, reducing additional drive devices and mechanical components, and making the equipment more concise and efficient.

[0023] The inkjet head 16 is one of the core components of digital inkjet printing. It will generate a certain amount of heat during its operation. If the temperature is too high, the inkjet head 16 will be blocked, the inkjet accuracy will be reduced, and even the inkjet head 16 will be damaged. Therefore, a cooling system needs to be set near the inkjet head 16. When working, the cooling box 13 generates cold air and transports it to the left guide air box 30 through a pipeline. The driving motor 19 drives the fan blades in the left guide air box 30 through a bevel gear to operate, and transports the cold air to the cooling nozzle 17. The cooling nozzle 17 can spray out cooling airflow to help keep the temperature of the inkjet head 16 stable.

[0024] After each cup is ink-sprayed, a drying system needs to be set on the disc 12. The drying system blows hot air to the ink-sprayed surface through a fan to quickly evaporate water or solvent to ensure that the ink dries quickly. During operation, the drying box 14 generates hot air, which is transported to the right guide air box 30 through a pipe. The drive motor 19 drives the fan blades in the right guide air box 30 through a bevel gear, and then transports the hot air to the drying nozzle 18 through a pipe to ensure that the ink on the entire cup surface dries quickly.

[0025] Furthermore, a discharge hole 101 and a feed hole 102 are provided on the surface of the housing 10 . A material guide trough 103 is installed at the discharge hole 101 , and a material conveyor 40 is provided at the feed hole 102 .

[0026] During operation, the material conveyor 40 transfers the cup to be printed from the previous working point to the surface feed hole 102 of the shell 10. The material conveyor 40 is provided with components such as a telescopic cylinder, which can push the cup to be printed to the outer ring of the roller 21. This process is completed automatically without manual intervention, thereby improving production efficiency and reducing errors caused by improper manual operation.

[0027] Furthermore, the inflator 26 is fixedly connected to the top of the rotary motor 20 , and the support member 27 is fixedly connected to the top of the disc 12 .

[0028] Furthermore, the cooling box 13 and the drying box 14 are both installed in the inner cavity of the shell 10, and the ink supplier 15 is connected to the inkjet head 16 through a pipeline. The inkjet head 16 is a digital inkjet printer nozzle. The inkjet head 16 is used to accurately spray ink onto the surface of the cup to form a desired pattern, text or image. The inkjet head 16 adopts thermal bubble or piezoelectric technology, and can adjust the inkjet accuracy, color, granularity, etc. as needed. The number of inkjet heads 16 may be set to multiple stations according to needs to support multi-color printing.

[0029] Furthermore, a telescopic rod 41 is fixed to the output end of the driving motor 19, and a convex column 121 is provided at the bottom of the disc 12, which penetrates into the inner cavity of the supporting column 11 and is rotatably connected to the supporting column 11, and the telescopic end of the telescopic rod 41 penetrates into the inner cavity of the convex column 121 and is clamped therewith.

[0030] During operation, when the telescopic end of the telescopic rod 41 penetrates into the inner cavity of the boss 121, the driving motor 19 can drive the disc 12 to rotate, and then drive the drum 21 and the cup to rotate. When the telescopic end of the telescopic rod 41 is separated from the inner cavity of the boss 121, the driving motor 19 will not drive the drum 21 and the cup to rotate. At this time, the driving motor 19 can drive the fan blades in the guide bellows 30 to operate through the bevel gear.

[0031] Furthermore, the output end of the driving motor 19 is sleeved with a main bevel gear 42, and auxiliary bevel gears 43 are meshed on both sides of the main bevel gear 42. The auxiliary bevel gear 43 is fixed with a rotating rod 44 that passes through the support column 11 and the guide air box 30, and the rotating rod 44 is fixed with the guide blade 31.

[0032] During operation, the output end of the driving motor 19 drives the main bevel gear 42 to rotate, and then drives the auxiliary bevel gears 43 on both sides to rotate. The auxiliary bevel gears 43 drive the guide blades 31 to operate through the rotating rod 44.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
