Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, and in particular to a cardboard positioning device and inkjet printing equipment. Background Technology

[0002] Digital inkjet printing has advantages such as fast production speed, no need for plate making, printing from a single sheet, environmentally friendly raw materials, low cost, wide range of orders, and ability to meet personalized customization. This has made inkjet printing equipment using digital inkjet technology the mainstream method for paperboard printing.

[0003] Currently, the main digital inkjet printing methods for cardboard are scanning and single-pass printing (a technology that uses high-speed movement of cardboard and a fixed printhead to eject ink to complete full-width printing). However, both scanning and single-pass digital inkjet printing require leading-edge feeding.

[0004] Common types of front edge feeding include lifting plate feeding and pressure-free feeding. Traditional structures of lifting plate feeding and pressure-free feeding both include a rear support plate assembly. The rear support plate assembly has the following functions, including but not limited to: multiple cardboards are stacked on the rear support plate assembly. In order to prevent long cardboards from deviating during the conveying process, the operator usually adds a cardboard positioning device at the middle of the long cardboard near the tail to block the opposite sides of the long cardboard in its width direction to correct the feeding direction of the cardboard.

[0005] However, in traditional cardboard positioning devices, the two baffles that are set opposite each other are manually adjusted. That is, the operator needs to repeatedly adjust the two baffles located on the operating side and the non-operating side of the printing equipment according to the width of the cardboard to achieve the positioning or correction of the cardboard.

[0006] Therefore, traditional cardboard positioning devices still have some drawbacks: for wide-format inkjet printing equipment, when operating alone, one person needs to walk back and forth between the operating side and the non-operating side of the inkjet printing equipment to adjust the position of the two baffles. This not only greatly increases the preparation time when changing different orders, resulting in low paper feeding efficiency, but also increases the labor intensity of the operator. It is also easy to cause low paper feeding accuracy due to manual adjustment errors. Two people operating the equipment will increase labor costs. Utility Model Content

[0013] In some embodiments, when the inner wall surface of the linear bearing abuts against the outer surface of the guide shaft, the third baffle is locked onto the linear bearing via the linear bearing.

[0022] The present invention will now be described in detail with reference to specific embodiments. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

Thus, features defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature. "A plurality" or "several" means two or more. In addition, "and / or" includes any and all combinations of one or more of the related listed items. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In this embodiment, the specific shape, structure and size of the "cardboard positioning device and printing equipment" are not limited. Those skilled in the art can selectively use any suitable implementation method according to actual needs.

[0025] In the following description, such as Figures 1-7 As shown, the following situation exists: the first direction, the width direction of the paperboard, or the direction in which the paperboard is tilted during transportation is defined as the X direction; the second direction, the length direction of the paperboard, or the transportation direction of the paperboard (the transportation direction of the paperboard is the paper feeding direction) is defined as the Y direction; the stacking direction is defined as the Z direction; the side of the inkjet printing equipment 100 opposite to the operator in the first direction that provides stacking operation, paper feeding operation, or software interface operation station is defined as the operating side 1001; and the other side of the inkjet printing equipment 100 opposite to the operating side 1001 in the first direction is defined as the non-operating side 1002; wherein, the X direction, Y direction, and Z direction are orthogonal to each other.

[0026] Please see Figure 1 and Figure 3The cardboard positioning device is applied to a printing equipment 100 having a rear tray assembly 9 and a paper feeding assembly, on which multiple cardboards (the cardboard is a printing substrate, such as corrugated cardboard for packaging) are stacked.

[0027] like Figures 1-7 As shown, the cardboard positioning device includes: a first baffle 1, a second baffle 2, a third baffle 3, a servo control module, and a manual adjustment module.

[0028] The first baffle 1 and the second baffle 2 are both at least partially connected to the servo control module, and the third baffle 3 is at least partially connected to the manual adjustment module. The servo control module is used to control the first baffle 1 and the second baffle 2 to move synchronously in the X direction, and the manual adjustment module is used to lock the third baffle 3 or guide the third baffle 3 to move in the X direction.

[0029] It should be noted that the cardboard positioning device drives the first baffle 1 and the second baffle 2 to move synchronously through a servo control module, thereby realizing the automatic adjustment of the first baffle 1 and the second baffle 2. This design allows the operator to simply input the width of the cardboard in the software interface on the main body 10 of the printing equipment 100 to move the first baffle 1 and the second baffle 2 located on the non-operating side 1002 of the printing equipment 100 to the preset first position, thus avoiding the operator having to run back and forth between the operating side 1001 and the non-operating side 1002 of the printing equipment 100 for repeated manual adjustments. Therefore, the cardboard positioning device can greatly shorten the preparation time when changing different orders, thereby improving the paper feeding efficiency of the printing equipment 100.

[0030] In addition, the first baffle 1 and the third baffle 3 are located on opposite sides of the rear support plate assembly 9 in the X direction, and the second baffle 2 is located on the side of the paper feeding assembly corresponding to the first baffle 1 in the X direction, and the first baffle 1 and the second baffle 2 are aligned with each other.

[0031] In addition, the first baffle 1 and the second baffle 2 move synchronously along the X direction to a preset first position, and the third baffle 3 moves along the X direction to a preset second position under the guidance of the manual adjustment module, so that the multiple cardboards stacked on the rear tray assembly 9 abut against the first baffle 1 and the third baffle 3 on opposite sides in the X direction.

[0032] It is understandable that the first baffle 1 and the second baffle 2 are aligned with each other, and the first baffle 1 and the second baffle 2 move synchronously to the preset first position. This ensures that the adjustment of the cardboard on the rear support plate assembly 9 and the paper feeding assembly adopts the same positioning reference. This design can avoid the cardboard from skewing due to inconsistent positioning references. Furthermore, the high precision of the servo control module further ensures the consistency of each adjustment, thereby eliminating the adjustment error caused by manual adjustment, thus improving the paper feeding accuracy of the printing equipment 100. This directly improves the registration accuracy and printing quality stability of the cardboard in subsequent printing processes, while reducing the scrap rate and downtime adjustment time caused by insufficient paper feeding accuracy.

[0033] In summary, this cardboard positioning device adopts a hybrid adjustment scheme with automatic adjustment as the primary method (both the first baffle 1 and the second baffle 2 on the non-operating side 1002 of the printing equipment 100 are automatically adjusted) and manual adjustment as a secondary method (the third baffle 3 on the operating side of the printing equipment 100 is manually adjusted). After the first baffle 1 and the second baffle 2 are automatically adjusted to the preset first position for precise positioning, the operator can start stacking cardboard on the operating side 1001 of the printing equipment 100. After the cardboard is stacked to the preset number of layers, the operator can manually push the third baffle 3 to the side of the cardboard that is close to the third baffle 3 in the X direction. When the third baffle 3 is close to the side of the cardboard that is close to the third baffle 3 in the X direction... The operator can reduce the inner diameter of the linear bearing 62 by tightening the handle 63, so that the inner wall of the linear bearing 62 abuts against the outer surface of the guide shaft 61, thereby locking the third baffle 3. This design allows the operator to complete all paper feeding preparations without leaving the operating side 1001 of the printing equipment 100, thereby reducing the preparation time when changing different orders. The cardboard positioning device delegates the complex and labor-intensive parts to the automation module, while the operator only needs to perform a simple final confirmation action that does not require much effort. This design can effectively reduce the operator's labor intensity, and at the same time make it easier and safer for a single person to operate a large wide-format printing equipment.

[0034] In some embodiments, such as Figure 1 , Figure 2 and Figure 7 As shown, the servo control module includes: a first servo component and a second servo component.

[0035] The first servo component is located on the rear support plate assembly 9, and the first baffle 1 is at least partially connected to the first servo component.

[0036] In addition, the second servo component is located on the paper feeding assembly, and the second baffle 2 is at least partially connected to the second servo component.

[0037] Furthermore, the first servo component and the second servo component have the same parameters so that the first baffle 1 and the second baffle 2 move synchronously.

[0038] In some embodiments, such as Figure 5 and Figure 7 As shown, the first servo component includes: a first lead screw 41, a first reducer 42, a first servo motor 43, and a first nut 44.

[0039] It should be noted that one end of the first lead screw 41 is connected to the first reducer 42, and the other end of the first lead screw 41 extends along the X direction toward the middle position of the rear support plate assembly 9.

[0040] It is understood that the first servo motor 43 is connected to the first reducer 42, the first nut 44 is sleeved on the first lead screw 41, and the first baffle 1 is connected to the first nut 44.

[0041] Specifically, the first servo motor 43 drives the first reducer 42 to cause the first lead screw 41 and the first nut 44 to move relative to each other, so that the first baffle 1 moves in the X direction.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the second servo component includes: a second lead screw 51, a second reducer 52, a second servo motor 53, and a second nut 54.

[0043] In this embodiment of the application, one end of the second lead screw 51 is connected to the second reducer 52, and the other end of the second lead screw 51 extends along the X direction toward the middle position of the paper feeding assembly.

[0044] Specifically, the second servo motor 53 is connected to the second reducer 52, the second nut 54 is sleeved on the second lead screw 51, and the second baffle 2 is connected to the second nut 54.

[0045] To further explain, the second servo motor 53 drives the second reducer 52 to cause the second lead screw 51 and the second nut 54 to move relative to each other, so that the second baffle 2 moves in the X direction.

[0046] In some embodiments, such as Figures 5-7 As shown, the manual adjustment module includes: a guide shaft 61, a linear bearing 62, and a locking handle 63.

[0047] The guide shaft 61 extends along the X direction toward the middle position of the rear support plate assembly 9, the linear bearing 62 is sleeved on the guide shaft 61, the locking handle 63 is set on the linear bearing 62, and the third baffle 3 is connected to the linear bearing 62.

[0048] In addition, the locking handle 63 is used to change the diameter of the inner hole of the linear bearing 62 so that the inner wall surface of the linear bearing 62 abuts against or separates from the outer surface of the guide shaft 61.

[0049] In addition, the linear bearing 62 is equipped with a fixing screw. After the third baffle 3 is manually moved to the preset third position (the third position is the position where the third baffle 3 is close to the side of the cardboard in the X direction), the linear bearing 62 is locked in the third position by the locking handle 63.

[0050] In some embodiments, such as Figures 5-7 As shown, when the inner wall surface of the linear bearing 62 abuts against the outer surface of the guide shaft 61, the third baffle 3 is locked onto the linear bearing 62 via the linear bearing 62.

[0051] In some embodiments, such as Figures 5-7 As shown, when the inner wall surface of the linear bearing 62 separates from the outer surface of the guide shaft 61, the third baffle 3 moves along the X direction under the guidance of the guide shaft 61.

[0052] In some embodiments, such as Figures 1-7 As shown, the cardboard positioning device also includes: a fourth baffle 7 and a cooperative control component.

[0053] It should be noted that the fourth baffle 7 is connected to the cooperative control component. The fourth baffle 7 and the second baffle 2 are located on opposite sides of the paper feeding assembly in the X direction, and the fourth baffle 7 and the third baffle 3 are located on the same side.

[0054] It is understandable that the second servo component and the cooperative control component control the second baffle 2 and the fourth baffle 7 to move synchronously towards each other or away from each other along the X direction relative to the middle position of the paper feeding assembly.

[0055] Specifically, the third baffle 3 moves along the X direction under the guidance of the guide shaft 61 until the third baffle 3 is aligned with the fourth baffle 7.

[0056] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the collaborative control components include a collaborative lead screw 81, a collaborative reducer 82, a collaborative servo motor 83, and a collaborative nut 84.

[0057] One end of the cooperating lead screw 81 is connected to the cooperating reducer 82, and the other end of the cooperating lead screw 81 extends along the X direction toward the middle position of the paper feeding assembly.

[0058] In addition, the collaborative servo motor 83 is connected to the collaborative reducer 82, the collaborative nut 84 is sleeved on the collaborative lead screw 81, and the fourth baffle 7 is connected to the collaborative nut 84.

[0059] In addition, the cooperative servo motor 83 drives the cooperative reducer 82 to cause the cooperative lead screw 81 and the cooperative nut 84 to move relative to each other, so that the fourth baffle 7 moves in the X direction.

[0060] In this embodiment, the fourth baffle 7 and the second baffle 2 can be controlled independently or uniformly.

[0061] Specifically, the printing equipment uses a centered paper feeding system for 100 pairs of cardboard. Therefore, when the operator inputs the width of the cardboard in the software interface, the second baffle 2 and the fourth baffle 7 will move to the center of the paper feeding assembly at the same time.

[0062] In some embodiments, such as Figures 5-7 As shown, the rear pallet assembly 9 has a separating paperboard 91 and a supporting paperboard 92.

[0063] It should be noted that the upper surface of the support plate 92 is usually flat, and the support plate 92 is used to support longer pieces of cardboard, that is, multiple longer pieces of cardboard can be stacked in the Z direction of the support plate 92.

[0064] In this embodiment, the tray 92 has multiple square grooves 921, at least a portion of the guide shaft 61 and the linear bearing 62 can be exposed from the square grooves 921, and at least a portion of the locking handle 63 can extend through the square grooves 921.

[0065] In some embodiments, such as Figures 5-7 As shown, in order to make the movement of the first baffle 1 more stable, a pair of support rods 901 and a pair of slide cylinders 902 sleeved on the pair of support rods 901 can be provided on both sides of the first baffle 1.

[0066] Understandably, the paper divider 91 is located on the side of the paper tray 92 in the Y direction near the paper feeding assembly, and the paper divider 91 can divide shorter paper trays. This design can effectively avoid high resistance caused by the paper trays being stacked too high.

[0067] In some embodiments, such as Figures 1-7 As shown, multiple cardboards stacked on the rear pallet assembly 9 are conveyed one by one into the paper feeding assembly along the Y direction.

[0068] In this embodiment of the application, when the second baffle 2 and the fourth baffle 7 move synchronously toward each other in the X direction relative to the middle position of the paper feeding assembly, the paperboard located in the paper feeding assembly abuts against the second baffle 2 and the fourth baffle 7 on opposite sides in the X direction.

[0069] Please continue reading. Figures 1-7The printing equipment 100 includes: equipment body 10, rear support plate assembly 9, paper feeding assembly and the aforementioned cardboard positioning device.

[0070] Specifically, the rear support plate assembly 9 and the paper feeding assembly are both mounted on the equipment body 10, and the first baffle 1, the first servo component, the third baffle 3 and the manual adjustment module in the paperboard positioning device are all integrated on the rear support plate assembly 9.

[0071] To further explain, the rear pallet assembly 9 can move in the Y direction via the geared motor 11, and the rear pallet assembly 9 can also move in the Z direction via the first handwheel 12.

[0072] When printing cardboard of different specifications, the operator can adjust the rear pallet assembly 9 to the appropriate position using the geared motor 11 and the first handwheel 12.

[0073] In this embodiment, the paper divider 91 can be adjusted to a suitable position by the second handwheel 13 to divide the paper, which is beneficial to the conveying of the paper.

[0074] In this embodiment, the device body 10 is equipped with a PLC (Programmable Logic Controller), and the first servo motor 43 and the second servo motor 53 are controlled by the same PLC. The first lead screw 41 and the second lead screw 51 have the same parameters (e.g., pitch parameters, lead parameters, etc.), the first reducer 42 and the second reducer 52 have the same parameters (e.g., reduction ratio parameters, rated output torque parameters, etc.), and the first nut 44 and the second nut 54 have the same parameters (e.g., pitch parameters adapted to the first lead screw 41 and the second lead screw 51, etc.), so that the first baffle 1 and the second baffle 2 can move synchronously.

[0075] Specifically, the traditional cardboard positioning device is a detachable side gauge assembly, so the traditional cardboard positioning device only has two side plates corresponding to the operating side and the non-operating side of the printing equipment, respectively.

[0076] It should be noted that the traditional cardboard positioning device is independent of the rear support plate assembly (i.e., the two side plates in the traditional cardboard positioning device are independent of the rear support plate assembly).

[0077] When feeding longer cardboard, the operator needs to move the traditional cardboard positioning device up and place it in the middle of the long cardboard, slightly towards the tail, to assist in positioning or correcting the wide side of the long cardboard (the wide side refers to the two opposite sides of the cardboard in the X direction).

[0078] When feeding shorter cardboard, there is no need to use a traditional cardboard positioning device to position or correct the wide side of the short cardboard. In this case, the operator needs to take the traditional cardboard positioning device that was brought up during the printing process of the previous long cardboard order down again.

[0079] For customers with a large number of small orders, the frequency of adjusting traditional cardboard positioning devices will be relatively high. Therefore, the non-integrated design and manual adjustment design of traditional cardboard positioning devices are not conducive to the flexible production needs of small batches and multiple varieties, and at the same time, they can easily increase the labor intensity of operators.

[0080] It is understandable that the first baffle 1, the first servo component, the third baffle 3, and the manual adjustment module in the cardboard positioning device are all integrated on the rear support plate assembly 9. This eliminates the need for the operator to move the first baffle 1 and the third baffle 3. Moreover, the first baffle 1 can automatically move to the preset first position according to the cardboard specifications set by the operator. Therefore, this integrated design is suitable for flexible production needs of small batches and multiple varieties, while also reducing the workload of the operator.

[0081] To further explain, the traditional cardboard positioning device operates by first placing paper and then adjusting. The operator needs to place a small amount of cardboard for reference, then move to the non-operating side of the printing equipment and manually press one of the two baffles corresponding to the non-operating side of the printing equipment against the cardboard until that baffle is adjusted to the designated position. Then, the operator returns to the operating side of the printing equipment to adjust the other baffle. In contrast, this cardboard positioning device allows for adjustment before placing paper. After the operator inputs the width of the cardboard in the software interface, the first baffle 1 and the second baffle 2 automatically move to the preset first position. The operator can then stack the cardboard in place continuously and in one go. Finally, the operator only needs to manually push the third baffle 3 against the cardboard and lock it in place. Therefore, compared to the traditional cardboard positioning device, the entire paper placement process of this device is smoother, avoiding the risk of interference with already stacked cardboard during adjustment, and further improving the convenience and safety of operation.

[0082] In summary, this cardboard positioning device integrates the first baffle 1, the first servo component, the third baffle 3, and the manual adjustment module onto the rear support plate assembly 9. The first baffle 1, located on the non-operating side 1002 of the printing equipment 100, is adjusted synchronously with the second baffle 2 according to the length of the order cardboard through the servo control module. The third baffle 3, located on the operating side 1001 of the printing equipment 100, is manually adjusted and locked. After the first baffle 1 is adjusted to the preset first position, cardboard is stacked on the rear support plate assembly 9. Then, the operator manually moves the third baffle 3 towards the cardboard and locks the locking handle 63. This cardboard positioning device not only reduces the adjustment time of the first baffle 1 but also eliminates the lifting operation of traditional cardboard positioning devices, thereby saving labor costs for the printing equipment 100 and reducing the labor intensity of the operator.

[0083] In summary, the cardboard positioning device and printing equipment provided by this utility model embodiment enable the cardboard positioning device to drive the first baffle and the second baffle to move synchronously via a servo control module. This achieves automated adjustment of the first and second baffles, avoiding repeated manual adjustments by the operator on both the operating and non-operating sides of the printing equipment. This design significantly shortens the preparation time and improves the paper feeding efficiency of the printing equipment. The first and second baffles are aligned with each other and move synchronously to a preset first position. This ensures that the cardboard is adjusted on the rear support assembly and the paper feeding assembly using the same positioning reference. This design avoids cardboard skewing caused by inconsistent positioning references. Furthermore, the high precision of the servo control module further ensures the consistency of each adjustment, eliminating adjustment errors caused by manual adjustments and improving the paper feeding accuracy of the printing equipment. In conclusion, this cardboard positioning device enables the printing equipment to have higher paper feeding efficiency, higher paper feeding accuracy, and lower labor costs, while also reducing the operator's workload.
