Description

Technical Field

[0001] This utility model belongs to the field of printing technology, and specifically relates to a transmission drying device suitable for the watermarking process in packaging. Background Technology

[0002] Packaging printing is based on various packaging materials such as paper, plastic, and metal. By printing exquisite decorative patterns, vivid designs, and detailed text on the packaging surface, it can not only enhance the visual appeal of the product and improve the brand image, but also clearly convey product information to consumers, thereby stimulating purchasing desires and increasing product sales. After the packaging printing is completed, the drying process is a key step to ensure printing quality.

[0003] For example, Chinese Patent No. CN217259087U discloses a transmission drying device suitable for watermarking processes in packaging, including a workbench and a support frame. A duct is rotatably connected between two of the supports frame. The duct is hollow inside, and several sliding rods are arranged in a circular array inside the duct. The sliding rods are elastically connected to the duct. Sliding blocks are fixedly connected to both ends of the sliding rods. Pushing slides are fixedly connected to both sides of the upper surface of the workbench. Multiple sets of through holes are arranged in a circular array on the duct, and rubber plugs are slidably embedded inside the through holes.

[0004] While the aforementioned patent addresses the issues of existing drying mechanisms, which often involve passing packaging through a heating oven (requiring a large oven size and space) or using hot air for drying with poor results, the device still has other shortcomings that require improvement. The air duct is fixed to the support via bearings. During long-term continuous operation, the grease inside the bearings deteriorates due to friction, heat generation, and oxidation, leading to reduced viscosity and lubrication. This significantly increases the resistance during air duct rotation, reducing transmission efficiency and consequently affecting the overall operating speed of the drying device and production efficiency. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a transmission drying device suitable for the watermarking process in packaging, so as to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A transmission drying device suitable for watermarking processes in packaging includes a workbench. Supports are fixedly connected to both sides of the workbench. Bearing outer rings are fixedly connected to the interior of both sides of the support. Inner bearing rings are rotatably connected to the inner side of the outer bearing rings. A rotating shaft is fixedly connected to the inner side of the inner bearing ring. A fan duct is fixedly connected to one side of the rotating shaft. An oil storage mechanism is provided on the upper side of the support. An oil injection pipe is fixedly connected to one side of the oil storage mechanism. A micro oil pump is fixedly connected to the middle of the oil injection pipe. One side of the oil injection pipe is fixedly connected to one side of the outer bearing ring. An oil discharge pipe is fixedly connected to the side of the outer bearing ring away from the oil injection pipe. A detection chamber is opened on one side of the support. A micro vibration viscosity sensor is fixedly connected to one side of the detection chamber. A second solenoid valve is fixedly connected to one side of the oil discharge pipe.

[0008] As a preferred technical solution, the oil storage mechanism includes an oil storage box, which is fixedly connected to the top of the support. An oil guide pipe is fixedly connected to the bottom of the oil storage box. A first solenoid valve is fixedly connected to one side of the oil guide pipe. The bottom of the oil guide pipe is fixedly connected to the top of the oil injection pipe. An agitation component is provided on one side of the oil storage box.

[0009] As a preferred technical solution, the agitation assembly includes a first stirring frame, which is rotatably connected to one side of the inside of the oil storage box. A second stirring frame is rotatably connected to one side of the first stirring frame inside the oil storage box. A first gear is fixedly connected to one side of the first stirring frame extending out of the oil storage box. A second gear is meshed with one side of the first gear. One side of the second gear is fixedly connected to one side of the second stirring frame. A motor is fixedly connected to the side of the first stirring frame away from the first gear. The motor is fixedly connected to the oil storage box.

[0010] As a preferred technical solution, one side of the oil drain pipe extends into the interior of the detection chamber, and the oil drain pipe is located directly above the micro vibration viscosity sensor.

[0011] As a preferred technical solution, guide seats are fixedly connected to both sides of the micro vibration viscosity sensor inside the detection cavity, and one side of the guide seats is inclined.

[0012] In summary, the present invention has the following main advantages:

[0013] First, this utility model, by fixing an oil injection pipe on the outer ring of the bearing, fixing a micro oil pump on the oil injection pipe, connecting the oil injection pipe to an oil guide pipe, and connecting the oil guide pipe to an oil storage box, utilizes the micro oil pump to draw lubricating oil from the oil storage box into the space between the outer and inner rings of the bearing, eliminating the air duct rotation resistance caused by poor bearing lubrication, ensuring the continuous, stable, and efficient operation of the drying device, avoiding the slowdown in production speed caused by reduced transmission efficiency, and ensuring the smooth progress of the packaging watermarking process;

[0014] Secondly, this utility model involves opening a detection chamber within a bracket, fixing a miniature vibratory viscosity sensor inside the detection chamber, connecting an oil drain pipe to the detection chamber, and connecting the oil drain pipe to the outer ring of the bearing. Opening the second solenoid valve allows the oil between the outer and inner rings of the bearing to contact the miniature vibratory viscosity sensor. The vibrating element vibrates in the grease, and the viscosity of the grease is accurately measured based on changes in vibration frequency or amplitude. When the viscosity of the grease drops to a set threshold due to aging, contamination, or other reasons, the sensor transmits a signal to the control system, which then controls the oil reservoir to lubricate the bearing.

It includes a workbench 1, with supports 2 fixedly connected to both sides of the workbench 1. Bearing outer rings 6 are fixedly connected to the inside of both sides of each support 2. Bearing inner rings 5 ​​are rotatably connected to the inner side of each bearing outer ring 6. A rotating shaft 4 is fixedly connected to the inner side of each bearing inner ring 5. A fan duct 3 is fixedly connected to one side of the rotating shaft 4. An oil storage mechanism 9 is provided on the upper side of the support 2. An oil injection pipe 7 is fixedly connected to one side of the oil storage mechanism 9. A micro oil pump 8 is fixedly connected to the middle of the oil injection pipe 7. One side of the oil injection pipe 7 is fixedly connected to one side of the bearing outer ring 6, with the bearing outer ring 6 located away from the oil injection pipe 7. An oil drain pipe 10 is fixedly connected to one side of the bracket 2. A detection chamber 12 is opened on one side of the bracket 2. A cover plate is fixed to the detection chamber 12 on the bracket 2 by bolts for easy subsequent inspection and maintenance. A miniature vibration viscosity sensor 13 is fixedly connected to one side of the detection chamber 12. A second solenoid valve 11 is fixedly connected to one side of the oil drain pipe 10. An air blowing device can also be installed on the top of the detection chamber 12. A drainage channel is opened at the bottom of the detection chamber 12 at the location of the miniature vibration viscosity sensor 13. The air blowing device consists of a small air pump and multiple adjustable-angle air nozzles. The air nozzles spray compressed air into the detection chamber 12 to blow the residual lubricating oil into the drainage channel and accelerate the discharge of lubricating oil.

[0023] refer to Figure 3 The oil storage mechanism 9 includes an oil storage box 91, which is fixedly connected to the top of the bracket 2. An oil guide pipe 92 is fixedly connected to the bottom of the oil storage box 91. A first solenoid valve 93 is fixedly connected to one side of the oil guide pipe 92. The bottom of the oil guide pipe 92 is fixedly connected to the top of the oil injection pipe 7. An agitator 94 is provided on one side of the oil storage box 91. By setting up the oil storage mechanism 9, when the control system determines that the bearing needs lubrication, the first solenoid valve 93 is opened. Under the action of gravity, the lubricating oil in the oil storage box 91 flows into the oil injection pipe 7 through the oil guide pipe 92. Then, the micro oil pump 8 injects the lubricating oil between the outer ring 6 and the inner ring of the bearing. The oil storage mechanism 9 realizes the storage and automatic delivery of lubricating oil, replacing the manual lubrication method and avoiding the untimely and negligent operation of manual operation.

[0024] refer to Figures 3-4The agitation assembly 94 includes a first agitator 942, which is rotatably connected to one side of the inside of the oil storage box 91. A second agitator 943 is rotatably connected to one side of the first agitator 942 inside the oil storage box 91. A first gear 944 is fixedly connected to the side of the first agitator 942 extending out of the oil storage box 91. A second gear 945 is meshed with one side of the first gear 944. One side of the second gear 945 is fixedly connected to one side of the second agitator 943. The first agitator 942 is located away from the first gear 943. A motor 941 is fixedly connected to one side of the wheel 944, and the motor 941 is fixedly connected to the oil storage box 91. By setting the stirring component 94, during the storage of lubricating oil, the motor 941 drives the first stirring frame 942 to rotate. The first stirring frame 942 drives the second stirring frame 943 to rotate synchronously through the meshing transmission of the first gear 944 and the second gear 945, so as to stir the lubricating oil in the oil storage box 91. The stirring component 94 can prevent the lubricating oil from settling or separating due to long-term standing, and ensure the stability of the lubricating oil performance.

[0025] refer to Figure 3 One side of the oil drain pipe 10 extends into the interior of the detection chamber 12, and the oil drain pipe 10 is located directly above the micro vibration viscosity sensor 13. When it is necessary to detect the viscosity of the bearing grease, the second solenoid valve 11 is opened, and the lubricating oil between the outer ring 6 and the inner ring of the bearing flows into the detection chamber 12 through the oil drain pipe 10 under the action of gravity and drips onto the micro vibration viscosity sensor 13.

[0026] refer to Figure 3 Inside the detection chamber 12, guide seats 14 are fixedly connected to both sides of the micro vibration viscosity sensor 13. One side of the guide seat 14 is inclined. By setting the guide seat 14, lubricating oil flows along the inclined guide seat 14 towards the sensor and finally covers the sensor surface.

[0027] Operating principle and advantages: The control system periodically opens the second solenoid valve 11 according to a set program. Under gravity, the lubricating oil between the outer ring 6 and the inner ring of the bearing flows through the oil drain pipe 10 into the detection chamber 12 and drips onto the miniature vibration viscosity sensor 13. The vibrating element vibrates within the grease, and the viscosity of the grease is accurately measured based on changes in vibration frequency or amplitude. When the viscosity of the grease drops to a set threshold due to aging, contamination, or other reasons, the sensor transmits a signal to the control system, controlling the oil storage mechanism 9 to operate. The motor 941 then drives the first... The stirring frame 942 rotates, and the first stirring frame 942 drives the second stirring frame 943 to rotate synchronously through the meshing transmission of the first gear 944 and the second gear 945, stirring the lubricating oil in the oil storage box 91. The stirring component 94 can prevent the lubricating oil from settling or separating due to long-term standing. Then, the micro oil pump 8 can draw the lubricating oil in the oil storage box 91 into the space between the outer ring 6 and the inner ring 5 of the bearing, eliminating the rotational resistance of the air duct 3 caused by poor bearing lubrication, and ensuring the continuous, stable and efficient operation of the drying device.
