Description

Technical Field

[0001] This application relates to the field of printing, and in particular to a printing apparatus. Background Technology

[0002] Currently, printing equipment for cardboard generally includes a feeding system and a printing system. The feeding system is used to transport the cardboard to the printing system for printing.

[0003] In related technologies, a feeding system generally includes a frame, a feeding platform, and a conveying mechanism. The feeding platform is slidably connected to the frame in the vertical direction. The feeding platform is raised and lowered by a servo motor. The conveying mechanism is located above the feeding platform. In use, stacked cardboard is placed on the feeding platform, and then the cardboard on the feeding platform is transported by the conveying mechanism. The servo motor controls the feeding platform to rise to compensate for the height loss of the stacked cardboard after it is partially transported by the conveying mechanism.

[0004] Regarding the aforementioned technologies, after the stacked cardboard on the loading platform is completely conveyed, a forklift is needed to place the stacked cardboard onto the loading platform. Before the stacked cardboard is placed on the loading platform, the loading system cannot work effectively, thus affecting production efficiency. Summary of the Invention

[0005] To improve production efficiency, this application provides a printing device.

[0006] This application provides a printing device that adopts the following technical solution:

[0007] A printing apparatus includes a printing system for printing paperboard and a feeding system for conveying paperboard to the printing system. The feeding system includes a frame, a conveying mechanism and a lifting mechanism mounted on the frame. The lifting mechanism includes a chain and two sprockets. The sprockets are rotatably connected to the frame. A motor for driving the sprockets is mounted on the frame. The chain is simultaneously sleeved on and meshed with the two sprockets. A plurality of support plates for carrying stacks of paperboard are fixedly connected at intervals on the chain. At least two support plates are simultaneously located on the same side of the chain's length. The conveying mechanism is located outside the range of motion of the support plates.

[0008] By adopting the above technical solution, during use, cardboard stacks are placed on a carrier plate, and the carrier plate is moved upward by a chain. The cardboard stacks on the carrier plate are then transported one by one to the printing system by a conveying mechanism. When the cardboard stack on the previous carrier plate is used up, the cardboard stack on the next carrier plate continues to move to the position of the conveying mechanism for cardboard transport. The reciprocating motion of the carrier plate is realized through the setting of chains and sprockets, and multiple carrier plates ensure a continuous supply of cardboard stacks. Thus, the printing system does not need to wait for the feeding system to replenish the cardboard stacks, thereby improving production efficiency.

[0009] Optionally, the feeding system also includes a conveyor belt for conveying the cardboard stack onto a support plate.

[0010] By adopting the above technical solution, multiple cardboard stacks can be placed on the conveyor belt in actual use. After the carrier plate moves to the conveyor belt conveying end, the cardboard stacks are transported to the carrier plate by the conveyor belt, which facilitates the automatic feeding of cardboard stacks and achieves the purpose of automated production.

[0011] Optionally, a fixing plate for mounting the support plate is fixedly connected to the chain, the support plate is slidably connected to the fixing plate along its own thickness direction, and a driving component is provided on the support plate for driving the support plate to slide.

[0012] By adopting the above technical solution, in order to ensure uninterrupted material supply from the lifting mechanism, it is necessary to ensure continuous movement of the carrier plate. When the carrier plate moves to the position of the conveyor belt, the continuous movement of the carrier plate will affect the efficient transport of the cardboard stack on the conveyor belt to the carrier plate. At this time, the carrier plate is driven to slide by the drive component to counteract the movement of the carrier plate driven by the chain, so that the carrier plate can be in a relatively stationary state, which facilitates the transport of the cardboard stack on the conveyor belt to the carrier plate.

[0013] Optionally, the drive assembly includes a second motor and a gear, the gear being rotatably connected to the support plate, the second motor being used to drive the gear to rotate, and a rack being fixedly connected to the fixed plate and meshing with the gear.

[0014] By adopting the above technical solution, when the carrier plate is driven to move, the second motor is turned on, which drives the gear to rotate. Since the gear and rack are meshed and connected, the rotation of the gear can drive the carrier plate to move. The drive assembly has a simple structure and is easy to operate.

[0015] Optionally, an extension plate is inserted into the end of the support plate away from the chain along its own width direction, and the frame is provided with a drive component for driving the extension plate to slide.

[0016] By adopting the above technical solution, the driving component can drive the extension plate to slide, thereby adjusting the length of the bearing plate, reducing the range of motion of the bearing plate, and increasing the support area of ​​the cardboard stack to ensure the stability of the cardboard stack.

[0017] Optionally, the driving component includes an air pump, and the support plate has a slot for inserting the extension plate, with the air pump outlet communicating with the slot.

[0018] By adopting the above technical solution, the extension plate can be slid by using an air pump to inflate and de-inflate the slot; the drive component has a simple structure and is easy to operate.

[0019] Optionally, an inflation tube communicating with the slot is fixedly connected to the support plate, and a vertically arranged baffle plate for closing the inflation tube is fixedly connected to the frame. An inflation hole is opened on the baffle plate, and the air outlet of the air pump is connected to the inflation hole. The support plate moves vertically so that the inflation tube is aligned with the inflation hole. When the support plate moves to the position of the conveying mechanism, the inflation tube disengages from the baffle plate. A spring for resetting the extension plate is provided in the slot.

[0020] By adopting the above technical solution, when the carrier plate moves to the position of the conveyor belt, the air hole and the air pipe are aligned. At this time, the air pump is turned on to inflate the slot, causing the extension plate to extend. Then, the cardboard stack is transported to the carrier plate by the conveyor belt. When the carrier plate moves to the position of the conveying mechanism, the cardboard on the carrier plate has been transported, and the air pipe is disengaged from the baffle plate. At this time, the slot can be deflated. Under the action of the spring, the extension plate returns to its original position, thereby reducing the movement range of the carrier plate. This setting allows the air pump to be placed on the frame and facilitates inflation of multiple slots.

[0021] Optionally, a side plate is fixedly connected to one end of the support plate near the chain.

[0022] By adopting the above technical solution, the weight of the cardboard stack becomes lower after the number of cardboard pieces on the support plate is reduced, making it easier to move. The movement of the cardboard stack can be prevented by setting side plates.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. This application achieves the reciprocating motion of the support plate by setting up chains and sprockets, and multiple support plates ensure a continuous supply of cardboard stacks, so that the printing system does not need to wait for the feeding system to replenish the cardboard stacks, thus improving production efficiency;

[0025] 2. When the cardboard stack is replenished to the carrier plate via the conveyor belt, the drive assembly can drive the carrier plate to slide to counteract the movement of the carrier plate driven by the chain, so that the carrier plate can be in a relatively stationary state, which facilitates the transfer of the cardboard stack on the conveyor belt to the carrier plate.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a printing apparatus. (Refer to...) Figure 1 The equipment includes a printing system 1 and a feeding system 2. The printing system 1 is used to print paperboard. In this embodiment, the printing system 1 is a printing machine, and the feeding system 2 is used to transport the paperboard to the printing system 1.

[0034] Reference Figure 1 and Figure 2 The feeding system 2 includes a frame 3, a conveying mechanism and a lifting mechanism mounted on the frame 3. There are two lifting mechanisms, which are arranged opposite to each other. The lifting mechanism includes two sets of lifting components, each including a chain 4 and two sprockets 5. The sprockets 5 are rotatably connected to the frame 3, and the axis of rotation of the sprockets 5 is set along the feeding direction of the printing system 1. A motor 6 is fixedly connected to the frame 3 by screws. The output shaft of the motor 6 is coaxially fixedly connected to one of the sprockets 5. The chain 4 is sleeved on both sprockets 5 and meshes with both sprockets 5. Multiple support plates 7 for carrying the cardboard stack 8 are fixedly connected at intervals on the chain 4. In this embodiment, there are four support plates 7. Two support plates 7 are located on the same side of the length direction of the chain 4, and the positions of the support plates 7 on the two chains 4 correspond one-to-one. The support plates 7 at the same height on the two chains 4 are used to jointly carry the same cardboard stack 8.

[0035] The conveying mechanism includes a roller 9 and a motor 10. The roller 9 is rotatably connected to the frame 3. The rotation axis of the roller 9 is set along the shortest line connecting the two chains 4. The roller 9 is located at the center of the two chains 4 and is outside the movement range of the bearing plate 7. The motor 10 is fixedly connected to the frame 3 by screws. The output shaft of the motor 10 is coaxially fixedly connected to a roller 11. The roller 9 is located above the roller 9 and abuts against the roller 9.

[0036] To facilitate automatic feeding of the carrier plate 7, the feeding system 2 also includes a conveyor belt 12, on which multiple cardboard stacks 8 are placed, and the length of the conveyor belt 12 is set along the feeding direction of the printing system 1.

[0037] Reference Figure 2 and Figure 3 In order to facilitate the smooth movement of the cardboard stack 8 on the conveyor belt 12 to the carrier plate 7, a fixed plate 13 for mounting the carrier plate 7 is fixedly connected to the chain 4. The carrier plate 7 is slidably connected to the fixed plate 13 along its own thickness direction. The carrier plate 7 is provided with a drive assembly, which is used to drive the carrier plate 7 to slide.

[0038] The drive assembly includes a second motor 14 and a gear 15. The second motor 14 is fixedly connected to the support plate 7 by screws. The output shaft of the second motor 14 is coaxially fixedly connected to the gear 15. The fixed plate 13 is fixedly connected to a rack 16 along its own length direction. The gear 15 and the rack 16 are meshed together.

[0039] When the carrier plate 7 moves to the position on the upper surface of the conveyor belt 12, the motor is turned on, which drives the gear 15 to rotate, thereby causing the carrier plate 7 to slide. This ensures that the sliding speed of the carrier plate 7 is consistent with the movement speed of the chain 4, so that the carrier plate 7 is in a relatively stationary state.

[0040] Reference Figure 2 and Figure 4 In addition, in order to make the support plate 7 more stable in supporting the cardboard stack 8, an extension plate 17 is inserted into the end of the support plate 7 away from the chain 4 along its own width direction. The support plate 7 has a slot 18 for inserting the extension plate 17, and the frame 3 is provided with a drive component for driving the extension plate 17 to slide.

[0041] The drive unit includes an air pump 19, an extension plate 17 and a sealed space between the inner wall of the slot 18, and the air pump 19 inflates or deflates the slot 18 through an air pipe 20.

[0042] Reference Figure 2 and Figure 3 In addition, to facilitate the installation of the air pump 19, a spring 21 is fixedly connected in the slot 18. The length direction of the spring 21 is set along the insertion direction of the extension plate 17. The other end of the spring 21 is fixedly connected to the extension plate 17. An inflation tube 24 communicating with the slot 18 is fixedly connected on the support plate 7. A vertically arranged baffle plate 22 for closing the inflation tube 24 is fixedly connected on the frame 3. The end of the inflation tube 24 away from the support plate 7 abuts against the baffle plate 22. An inflation hole 23 is opened on the baffle plate 22. The air outlet of the air pump 19 is connected to the air pipe 20. The other end of the air pipe 20 is connected to the inflation hole 23. When the upper surface of the support plate 7 and the upper surface of the conveyor belt 12 are aligned, the inflation hole 23 and the inflation tube 24 are aligned. When the upper surface of the extension plate 17 is about to abut the roller 9, the inflation tube 24 is disengaged from the baffle plate 22 and connected to the external connection.

[0043] In this embodiment, in order to compensate for the distance that the extension plate 17 rises during the process of the extension plate 17 being inserted into the slot 18 to disengage from the roller 9, a rubber ring 25 is fitted on the outer wall of the roller 9.

[0044] In addition, to prevent the cardboard stack 8 from shifting, a side plate 26 is fixedly connected to one end of the support plate 7 near the chain 4, which is arranged along the thickness direction of the support plate 7.

[0045] The implementation principle of a printing device according to an embodiment of this application is as follows: During use, when the carrier plate 7 moves to a position where its upper surface is flush with the upper surface of the conveyor belt 12, the air inflator 24 and the air inflator 23 on the baffle plate 22 are aligned. The air pump 19 is then turned on to inflate the slot 18, causing the extension plate 17 to extend. Simultaneously, the motor 14 is turned on, driving the gear 15 to rotate. Under the action of the rack 16, the carrier plate 7 moves downward relative to the chain 4, and the downward speed of the carrier plate 7 is consistent with the movement speed of the chain 4, thus extending the carrier plate 7. When plate 7 is in a relatively stationary state, the conveyor belt 12 is turned on to transport the cardboard stack 8 to the support plate 7. Then, the motor 14 is reversed or stopped to move the support plate 7 upward until the roller 9 touches the cardboard stack 8, transporting the cardboard on the cardboard stack 8 to the printing system 1. When the roller 9 touches the extension plate 17, the air tube 24 disengages from the shield plate 22 and connects to the outside. Under the action of the spring 21, the extension plate 17 is inserted into the support plate 7 and moves back to the position of the conveyor belt 12 for replenishment under the action of the chain 4.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
