Description

Technical Field

[0001] This application relates to the field of food bag printing technology, and more specifically, to a printing press for food bags that performs double-sided synchronous printing. Background Technology

[0002] Food bag printing refers to the process of printing patterns, text, and other information on food packaging bags. Its purpose is to enhance the aesthetics of the packaging, convey product information, and ensure food safety. The printing plate is the core tool of this process, used to design and create templates for printing patterns, text, and other information.

[0003] In related technologies, to achieve double-sided printing on food bags, for example, patent CN217917236U provides a double-sided printing mechanism for a printing machine used in food bag production. This device uses a cylinder to drive a conveyor belt to rise and fall, allowing the conveyor belt to move to the printing inlet and outlet of the printing machine to transport the food bags. A cylinder also drives a tilting plate to rise via a lifting plate, and a motor drives the tilting plate to tilt via a rotating rod. A motor drives a sliding plate to slide in a groove via a threaded rod. The sliding plate moves the cylinder, which in turn moves the tilting plate. This method automatically tilts the food bags, making it more convenient. The suction fan and suction holes can firmly hold the food bags in place, preventing them from falling when the tilting plate tilts, thus solving the problem that traditional printing machines cannot perform double-sided printing on food bags.

[0004] Although the existing technical solutions mentioned above can achieve the effect of double-sided synchronous printing on food bags by setting up a flip plate and a suction fan, it is not convenient for the printing press to quickly load and unload the food bags before and after printing, which affects the efficiency of food bag printing.

[0005] In view of this, we propose a printing press for food bags that performs simultaneous double-sided printing. Utility Model Content

[0009] The main body of the double-sided synchronous printing machine is located on top of the printing table;

[0010] The take-up and unwinding assemblies are respectively disposed on both sides of the body of the double-sided synchronous printing machine.

The end of the take-up and release roller away from the drive motor A is fitted to the inside of the movable base. The movable base is driven by an external force to move horizontally and synchronously drive the drive motor A to rotate a certain angle, which is used to drive one end of the take-up and release roller to rotate upward and lift it up.

[0016] As an optional solution to the technical solution of this application, a connecting frame is fixedly provided on the outer side of the drive motor A, and connecting columns are fixedly provided on both sides of the connecting frame. The ends of the two connecting columns that are far apart from each other pass through the fixing seat and are fixedly provided with the inner side of the corresponding gear.

[0017] As an optional solution to the technical solution in this application, a rotating roller is rotatably provided on the inner side of the movable seat to support the take-up and release rollers.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] Referring to the figures, this application discloses a printing machine for food bags with double-sided synchronous printing, including a base plate 1. A printing table 12 is fixedly mounted on the top of the base plate 1. A double-sided synchronous printing machine body 2 is mounted on the top of the printing table 12. Take-up and unwrap assemblies 3 are mounted on both sides of the double-sided synchronous printing machine body 2. The take-up and unwrap assemblies 3 include a fixed seat 31 and a movable seat 32. The fixed seat 31 is fixedly mounted on the top of the base plate 1, and the movable seat 32 is slidably mounted on the top of the base plate 1. Two limiting plates 4 are provided between the fixed seat 31 and the movable seat 32. The two limiting plates 4 are driven by external force to move closer or further away from each other to limit the food bag roll. A drive motor A33 is rotatably mounted on the inner side of the fixed seat 31. A take-up and unwrap roller 34 is fixedly mounted on the output end of the drive motor A33. The end of the take-up and unwrap roller 34 away from the drive motor A33 is fitted to the inner side of the movable seat 32. The movable seat 32 is driven by external force to move horizontally and synchronously drive the drive motor A33 to rotate at a certain angle to drive one end of the take-up and unwrap roller 34 to rotate upward and lift it.

[0032] Before printing on the food bags, the movable seat 32 is driven by external force to release the support of the take-up and release roller 34. At the same time, the drive motor A33 is driven to rotate, thereby causing the take-up and release roller 34 to rotate at a certain angle, so that one end of the take-up and release roller 34 rotates upward and lifts up, making it easier for the staff to put the unprinted food bag roll onto the take-up and release roller 34. Then, the movable seat 32 is driven by external force to drive the drive motor A33 to rotate, thereby causing the take-up and release roller 34 to rotate and reset, so that the movable seat 32 supports the take-up and release roller 34. Then, the two limiting plates 4 are driven by external force to move closer to each other to limit the food bag roll, completing the loading work before printing.

[0033] When printing on food bags, one end of the unprinted food bag is placed inside the body 2 of the double-sided synchronous printing machine. The body 2 of the double-sided synchronous printing machine is an existing technology device that can print on both sides of the food bag simultaneously.

[0034] After printing on the food bags, the two limiting plates 4 are driven away from each other by external force, releasing the restriction on the food bag roll. The moving seat 32 is then driven by external force to release its support on the take-up and release roller 34. At the same time, the drive motor A33 is driven to rotate, thereby causing the take-up and release roller 34 to rotate at a certain angle, so that one end of the take-up and release roller 34 rotates upward, making it easier for the staff to remove the printed food bag roll. Meanwhile, an unprinted food bag roll is put onto the take-up and release roller 34 on the other side, facilitating the loading and unloading work of the staff. Then, the moving seat 32 is driven to reset by external force, thereby driving the drive motor A33 and the take-up and release roller 34 to reset, so as to carry out the next printing work.

[0035] Referring to the figure, a set of sliding grooves A11 are provided on both sides of the top of the base plate 1. The movable seat 32 is fixedly installed at the output end of the hydraulic rod 321, which is fixedly installed on the top of the base plate 1. A set of sliders 322 are fixedly installed at the bottom of the movable seat 32. Connecting rods 323 are fixedly installed on both sides of the movable seat 32. Multiple toothed blocks 324 are fixedly installed on one side of the top of the connecting rods 323. Toothed columns 311 and gears 312 are rotatably installed on both sides of the fixed seat 31. Synchronous toothed belts 313 are meshed together on the outer sides of the toothed columns 311 and gears 312. The outer side of the drive motor A33 is engaged with multiple toothed blocks 324. A connecting frame 331 is fixedly installed on the outer side of the drive motor A33. A connecting column 332 is fixedly installed on both sides of the connecting frame 331. The ends of the two connecting columns 332 that are far apart from each other pass through the fixed seat 31 and are fixedly installed on the inner side of the corresponding gear 312. A rotating roller 325 is rotatably installed on the inner side of the moving seat 32 to support the take-up and release roller 34. A sliding groove B314 is opened on both sides of the fixed seat 31 at the bottom of the corresponding connecting rod 323. A sliding strip 3231 is fixedly installed on the bottom of the connecting rod 323 corresponding to the sliding groove B314.

[0036] Through the sliding engagement of slider 322 and slide groove A11, hydraulic rod 321 drives moving seat 32 to move on top of base plate 1. Under the sliding engagement of slide bar 3231 and slide groove B314, connecting rod 323 moves, causing connecting rod 323 to drive tooth block 324 to move. Tooth block 324 meshes with tooth column 311, causing tooth column 311 to rotate a certain angle. Through synchronous toothed belt 313, gear 312 rotates, causing gear 312 to drive connecting column 332 to rotate, thereby causing connecting frame 331 to rotate a certain angle. Drive motor A33 drives take-up and release roller 34 to rotate a certain angle, causing one end of take-up and release roller 34 to be raised, which facilitates the loading and unloading of food bag rolls.

[0037] During printing, the take-up roller 34 is rotated by engaging one end of the rotating roller 325 with the take-up roller 34, thereby reducing the friction between the take-up roller 34 and the moving seat 32.

[0038] Referring to the figure, a bidirectional lead screw 41 is engaged on the inner side of the two limiting plates 4. The bidirectional lead screw 41 is fixedly mounted on the output end of the drive motor B42. The drive motor B42 is fixedly mounted on the inner side of the fixed base 31. The end of the bidirectional lead screw 41 away from the drive motor B42 is rotatably mounted on the inner side of the connecting plate 44. The connecting plate 44 is fixedly mounted on the top of the base plate 1. The limiting plate 4 is slidably mounted on the outer side of the limiting post 43. The two ends of the limiting post 43 are respectively fixedly mounted on the inner side of the fixed base 31 and the movable base 32.

[0039] The bidirectional lead screw 41 is driven to rotate by the drive motor B42, which causes the two limiting plates 4 to slide outside the drive motor B42, so that the two limiting plates 4 move closer or further apart, thereby limiting or releasing the food bag roll.

[0040] In summary, during use, the double-sided synchronous printing machine for food bags disclosed in this application operates by sliding the slider 322 against the slide groove A11, driving the movable seat 32 to move on the top of the base plate 1 via the hydraulic rod 321. Under the sliding engagement of the slide bar 3231 and the slide groove B314, the connecting rod 323 moves, causing the connecting rod 323 to move the toothed block 324. The toothed block 324 meshes with the toothed column 311, causing the toothed column 311 to rotate at a certain angle. This, in turn, drives the gear 312 to rotate via the synchronous toothed belt 313, which in turn drives the connecting column 332 to rotate, thereby causing the connecting frame 331 to rotate at a certain angle. Drive motor A33 drives take-up roller 34 to rotate at a certain angle, causing one end of take-up roller 34 to rotate upward and lift, making it easier for the staff to put the unprinted food bag roll onto take-up roller 34. Then, external force drives moving seat 32, causing moving seat 32 to drive drive motor A33 to rotate, thereby causing take-up roller 34 to rotate and reset, and moving seat 32 to support take-up roller 34. Then, drive motor B42 drives bidirectional lead screw 41 to rotate, causing bidirectional lead screw 41 to drive two limiting plates 4 to slide outside of drive motor B42, so that the two limiting plates 4 move closer to each other to limit the food bag roll, completing the pre-printing loading work.

[0041] When printing on food bags, one end of the unprinted food bag is placed inside the body 2 of the double-sided synchronous printing machine. The body 2 of the double-sided synchronous printing machine is an existing technology device that can print on both sides of the food bag simultaneously.

[0042] After printing on the food bag, the bidirectional lead screw 41 is driven to rotate by the drive motor B42. This causes the bidirectional lead screw 41 to slide the two limiting plates 4 outside the drive motor B42, moving the two limiting plates 4 away from each other and releasing the restriction on the food bag roll. The slider 322 slides with the slide groove A11, and the hydraulic rod 321 drives the moving seat 32 to move on the top of the base plate 1. Under the sliding engagement of the slide bar 3231 and the slide groove B314, the connecting rod 323 moves, causing the connecting rod 323 to move the toothed block 324. The toothed block 324 meshes with the toothed column 311, causing the toothed column 311 to rotate a certain distance. The angle is determined by the synchronous toothed belt 313 driving the gear 312 to rotate, which in turn drives the connecting column 332 to rotate, thereby causing the connecting frame 331 to rotate at a certain angle. This causes the drive motor A33 to drive the take-up and release roller 34 to rotate at a certain angle, so that one end of the take-up and release roller 34 rotates upward and lifts up, making it easier for the staff to remove the printed food bag roll. At the same time, an unprinted food bag roll is put onto the take-up and release roller 34 on the other side, which facilitates the loading and unloading work of the staff. Then, the moving seat 32 is reset by external force, which in turn drives the drive motor A33 and the take-up and release roller 34 to reset, so as to carry out the next printing work.
