Description

Technical Field

[0001] This utility model relates to packaging equipment, specifically to an online printing medical dressing packaging machine. Background Technology

[0002] A medical dressing packaging machine is a device used for automated packaging of dressings. Traditional dressing packaging machines typically unwind pre-printed upper and lower packaging substrates and then package the dressing. However, this method is prone to errors during the unwinding and traction of the upper and lower packaging substrates, leading to misalignment of the patterns. This error is amplified, especially during prolonged packaging processes, resulting in noticeable misalignment of the upper and lower patterns after packaging, affecting the overall appearance. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide an online printing medical dressing packaging machine for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] An online printing medical dressing packaging machine includes a feeding conveyor belt, characterized in that: a lower packaging substrate unwinding roller is arranged below the feeding conveyor belt, the lower packaging substrate unwinding roller is used to unwind the already printed packaging bag substrate, a first color mark sensor is arranged on the conveying path of the already printed packaging bag substrate, an upper packaging substrate unwinding roller is arranged above the feeding conveyor belt, the upper packaging substrate unwinding roller is used to unwind the unprinted packaging bag substrate, a flexographic printing unit is arranged corresponding to the upper packaging substrate unwinding roller, a pressure roller is arranged at the feeding end of the flexographic printing unit, the pressure roller is arranged on a first swing frame, the first swing frame is connected to a swing drive assembly, the pressure roller can press the upper packaging substrate onto the rubber roller, a second color mark sensor is arranged at the output end of the flexographic printing unit, the first and second color mark sensors can feed back information to a controller, the controller can control the action of the swing drive assembly, and a heat sealing assembly, a cutting assembly and a feeding assembly are arranged sequentially on one side of the feeding conveyor belt.

[0006] The swing drive assembly includes a first cylinder, the piston rod of which is hinged to a first swing frame.

[0007] The flexographic printing unit includes a printing roller, a rubber roller, an anilox roller, an ink transfer roller, and an ink cartridge. One end of the rubber roller is connected to a first motor for transmission. A first gear and a second gear are connected to the rubber roller. The first gear meshes with a third gear, which is connected to the printing roller. The second gear meshes with a fourth gear, which meshes with a fifth gear, which is connected to the anilox roller.

[0008] A one-way bearing is provided between the fifth gear and the anilox roller. A drive shaft is provided on one side of the anilox roller. The drive shaft is connected to the second motor and to the motion drive assembly. A drive step is provided at one end of the drive shaft. A drive rod that cooperates with the drive step is provided on the anilox roller.

[0009] The ink cartridge is mounted on the second swing frame, and the ink transfer roller is rotatably mounted inside the ink cartridge. The second swing frame is provided with a support for placing the end of the anilox roller. The frame is provided with a semi-circular support seat, which can provide rotational support for the bearing on the anilox roller. The frame is provided with a swing limit block corresponding to the second swing frame.

[0010] A feed plate is provided at the output end of the flexographic printing unit, and a drying box is provided corresponding to the feed plate.

[0011] The online printing medical dressing packaging machine described above uses an independent flexographic printing unit to print on the packaging bag substrate that has not yet undergone printing processing in real time. It is equipped with first and second color mark sensors to detect the color marks on the upper and lower packaging bag substrates and feed the results back to the controller. The controller can control the movement of the swing drive component based on the color mark detection, so as to realize the conveying coordination between the pressure roller and the rubber roller, and to press or loosen the upper packaging substrate to meet the traction requirements of the subsequent upper packaging substrate. This ensures that the patterns on the upper and lower packaging substrates can be accurately aligned, thereby improving the aesthetics of the packaging. Attached Figure Description

[0019] As shown in the figure, the online printing medical dressing packaging machine disclosed in this utility model includes a feeding conveyor belt 1, a lower packaging substrate unwinding roller 7 disposed below the feeding conveyor belt 1, the lower packaging substrate unwinding roller 7 being used to unwind the already printed packaging bag substrate, a first color mark sensor 6 disposed on the conveying path of the already printed packaging bag substrate, and an upper packaging substrate unwinding roller 2 disposed above the feeding conveyor belt 1, the upper packaging substrate unwinding roller 2 being used to unwind the packaging bag substrate that has not yet been printed, and a first color mark sensor 6 disposed corresponding to the upper packaging substrate unwinding roller 2. The system includes a flexographic printing unit 3. A pressure roller 13 is installed at the feed end of the flexographic printing unit 3, and the pressure roller 13 is mounted on a first swing frame 12. The first swing frame 12 is connected to a swing drive assembly. The pressure roller 13 presses the upper packaging substrate firmly onto the rubber roller 14. A second color mark sensor 5 is installed at the discharge end of the flexographic printing unit. The first and second color mark sensors can provide feedback information to a controller, which can control the movement of the swing drive assembly. A heat sealing assembly 8, a cutting assembly 9, and a feeding assembly 10 are sequentially arranged on one side of the feed conveyor belt 1. The heat sealing assembly 8, the cutting assembly 9, and the feeding assembly 10 are common structures on the market and belong to existing technology. They do not involve the innovation points of this application, so their specific structures will not be described in detail.

[0020] Furthermore, the swing drive assembly includes a first cylinder 11, the piston rod of which is hinged to the first swing frame 12. By controlling the first cylinder 11, the first swing frame 12 can be driven to swing.

[0021] Furthermore, the flexographic printing unit includes a printing roller 19, a rubber roller 14, an anilox roller 24, an inking roller 23, and an ink cartridge 30. One end of the rubber roller 14 is connected to a first motor 16 for transmission. A first gear 17 and a second gear 20 are connected to the rubber roller 14. The first gear 17 meshes with a third gear 18, which is connected to the printing roller 19. The second gear 20 meshes with a fourth gear 21, which meshes with a fifth gear 22, which is connected to the anilox roller 24. With the above structure, by controlling the start of the first motor 16 and transmitting power through the gear set, the printing roller 19, the rubber roller 14, and the anilox roller 24 can be driven to rotate synchronously.

[0022] Furthermore, a one-way bearing is provided between the fifth gear 22 and the anilox roller 24. A drive shaft 26 is provided on one side of the anilox roller 24, and a support bearing 25 is provided at one end of the drive shaft 26. The support bearing 25 is fitted into the moving block 37. The piston rod of the second cylinder 36 is connected to the moving block 37. The drive shaft 26 is connected to the second motor 35, which can drive the rotating disk 27 to rotate. The drive shaft 26 is keyed to the rotating disk 27, so that the drive shaft 26 can both rotate and move. The drive shaft 26 is connected to the moving drive assembly. A drive step 28 is provided at one end of the drive shaft 26, and a drive rod 29 that cooperates with the drive step 28 is provided on the anilox roller 24. Using the above technical solution, when changing the printing roller, in order to prevent the ink on the anilox roller from drying and solidifying, the drive shaft 26 can be controlled to move closer to the anilox roller, so that the drive step 28 can cooperate with the drive rod 29, thereby driving the anilox roller to rotate continuously, so that the ink on the anilox roller will not solidify. At the same time, due to the presence of the one-way bearing, it is only necessary to drive the anilox roller to rotate in the opposite direction, so as to avoid driving the rubber roller to rotate, and the printing roller changing operation will not be disturbed.

[0023] Furthermore, the ink cartridge 30 is mounted on the second swing frame 31, and the ink transfer roller 23 is rotatably mounted inside the ink cartridge 30. The second swing frame 31 is provided with a support portion 34 for placing the end of the anilox roller 24. The frame is provided with a semi-circular support base 33, which can rotate and support the bearing 38 on the anilox roller 24. The frame is provided with a swing limit block 32 corresponding to the second swing frame 31. By adopting the above technical solution, the second swing frame 31 can be controlled to swing, thereby driving the entire ink cartridge 30 and the anilox roller 24 to swing to the ink transfer position or swing outward from the ink transfer position, thus facilitating cleaning or replacement of the anilox roller or ink cartridge.

[0024] A feed plate 15 is provided at the output end of the flexographic printing unit 3, and a drying box 4 is provided corresponding to the feed plate 15. By adopting the above technical solution, the packaging substrate can be supported and dried after printing, thus ensuring printing quality.

[0025] The working principle of this utility model is as follows: the dressing is placed on the feeding conveyor belt 1 for conveying. The lower packaging substrate is unwound by the lower packaging substrate unwinding roller 7 and sent to the discharge end of the feeding conveyor belt 1. The upper packaging substrate is unwound by the upper packaging substrate unwinding roller 2 and sent to the flexographic printing unit 3 for printing processing. After that, it is also pulled to the discharge end of the feeding conveyor belt 1. During the conveying process of the upper and lower packaging bag substrates, the first and second color mark sensors will detect the pattern color marks on the upper and lower packaging bag substrates respectively and feed back the information to the controller. The controller will analyze the pattern of the upper and lower packaging bag substrates based on the feedback color mark information. If the pattern on the upper packaging bag substrate is in front, the pressure roller 13 is controlled to press the upper packaging bag substrate onto the rubber roller 14, thus slowing down the traction of the upper packaging bag substrate. If the pattern on the upper packaging bag substrate is in the back, the pressure roller 13 is controlled to release the upper packaging bag substrate, so that the upper packaging bag substrate can be pulled to the subsequent position more quickly, thereby ensuring that the patterns on the upper and lower packaging bag substrates can be aligned. Then the material is fed onto the lower packaging bag substrate, and the upper and lower packaging bag substrates cover the material and are sent to the heat sealing assembly to heat seal the upper and lower packaging bag substrates together. Then it is sent to the cutting assembly 9 to be cut into individual bags and sent out through the feeding assembly 10.
