Description

Technical Field

[0001] The invention relates to the technical field of printing and typing equipment, and in particular to a bottom-mounted scanning and direct-output integrated machine. Background Art

[0002] A carton typewriter is a device specially used to print patterns, text, barcodes and other information on cartons. The carton typewriter is controlled by a computer and prints the designed pattern or information on the carton through a print head by thermal printing or inkjet. Carton typewriters are widely used in packaging, logistics, warehousing and other fields. In the packaging field, carton typewriters can be used to print information on product packaging boxes, such as product name, specifications, production date, etc.

[0003] Scanning mode and direct-out mode are two operating modes of carton typewriters. Scanning mode usually involves multiple scanning and printing processes. Scanning mode is relatively slow because the image needs to be scanned and processed multiple times. Scanning mode is suitable for occasions with high requirements on printing quality, such as artwork reproduction, high-end packaging, etc.

[0004] Direct-to-print mode is a more direct and faster way to print. Image data is directly imported into the printing press without multiple scans and processing. Direct-to-print mode is faster to print because image data is directly used for printing without additional processing steps, which makes direct-to-print mode have significant advantages when a large number of printing tasks need to be completed quickly. Direct-to-print mode is suitable for large-scale, low-cost printing tasks.

The utility model is not only simple and reasonable in structure design and convenient in operation, but also has good printing effect, strong practicality, and high market application value.

[0006] Due to the different specifications of the printed cardboard (such as the thickness of the cardboard), it is often necessary to adjust the position of the nozzle or the cardboard to ensure that the nozzle maintains an optimal distance from the printing surface so that the printer can achieve the best printing effect; when the device is in use, although it can adjust the distance between the workbench and the nozzle, the device lacks risk avoidance facilities. Due to the different specifications of the printed cardboard, in the process of adjusting the workbench close to the carton, it is inevitable that the cardboard on the workbench is too close to or touches the nozzle due to operational errors, resulting in poor printing quality of the device and even damage to the cardboard and the printer.

DETAILED DESCRIPTION

[0034] The following will refer to Figures 1 to 9 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0035] Hanging type scanning direct output all-in-one machine, such as Figure 1-Figure 5 As shown, it includes a trolley fixing frame 1 which can move laterally, and a mounting frame is vertically slidably cooperated on the trolley fixing frame 1, and a screw lift 3 and a nozzle are installed on the mounting frame, and the output end of the screw lift 3 is fixedly connected to the trolley fixing frame 1; a first motor 4 is installed on the mounting frame, and the first motor 4 is a servo motor, and the output end of the first motor 4 is linked with the power input end of the screw lift 3; the first motor 4 is provided with a one-way locking mechanism and a stall protector, and the stall protector is a prior art and will not be described in detail here; a trigger rod 5 is vertically slidably provided on the mounting frame, and the trigger rod 5 is linked with the one-way locking mechanism; a control system (such as a PLC controller, a computer control system, etc., which is a prior art and will not be described in detail here) is provided on the device, and the control system is electrically connected to the first motor 4. When the control system controls the first motor 4 to rotate forward, the screw lift 3 is driven to make the trolley fixing frame 1 move away from the mounting frame, that is, the mounting frame performs a descending movement.

[0036] It should be noted that, due to factors such as operating errors by staff, during the descent of the mounting frame, if the mounting frame descends to the point where the trigger rod 5 hits the object below (taking cardboard as an example in this embodiment), it proves that the mounting frame has descended excessively, and at the same time, the trigger rod 5 rises relative to the mounting frame, and the trigger rod 5 drives the one-way locking mechanism to lock the output end of the first motor 4, so that the output end of the first motor 4 can no longer rotate, that is, the mounting frame can no longer descend, thereby preventing the mounting frame and the nozzle from continuing to descend, resulting in poor printing quality or even damage to the device.

[0037] It is worth noting that after the one-way locking mechanism locks the output end of the first motor 4 , the first motor 4 will be automatically turned off through the setting of the stall protector, thereby achieving automatic stopping of the first motor 4 .

[0038] like Figure 3 and Figure 7 As shown, the trigger rod 5 is provided with a first electrode block 6, the mounting frame is provided with a second electrode block 7 and a third electrode block 8 matching the first electrode block 6, the second electrode block 7 is located above the third electrode block 8, and the mounting frame is provided with a first indicator light 9 and a second indicator light 10, the second electrode block 7 is electrically connected to the first indicator light 9, and the third electrode block 8 is electrically connected to the second indicator light 10; in this embodiment, the light color of the first indicator light 9 is red, and the light color of the second indicator light 10 is green. In the initial state, the first electrode block 6 is in contact with the third electrode block 8, that is, the second indicator light 10 is on and emits green light, proving that the device is in normal working state at this time; when the mounting frame drops excessively and causes the trigger rod 5 to rise relative to the mounting frame, the first electrode block 6 moves with the trigger rod 5 and no longer contacts the third electrode block 8, and the first electrode block 6 contacts the second electrode block 7. At this time, the first indicator light 9 emits red light to remind the staff that the device is in an abnormal working state at this time. It should be noted that in actual use, the first indicator light 9 is connected to an external alarm device. When the first indicator light 9 emits red light, it reminds the staff that the device is in an abnormal working state by issuing an alarm.

[0039] like Figure 3-Figure 5 As shown, the mounting frame is composed of a vertical plate 11 and a horizontal plate 12, the bottom of the horizontal plate 12 is fixedly connected to the top of the vertical plate 11, the nozzle is installed on the horizontal plate 12, and a concave slider 13 is fixedly connected to the side of the vertical plate 11 close to the trolley fixing frame 1, and a slide rail 14 is fixedly connected to the trolley fixing frame 1, and the concave slider 13 and the slide rail 14 are slidably matched. Through the matching setting of the concave slider 13 and the slide rail 14, the vertical plate 11 can move up and down relative to the trolley fixing frame 1.

[0040] like Figure 4-Figure 6 , Figure 8 and Fig. 9As shown, the one-way locking mechanism consists of a first limit assembly and a second limit assembly, the first limit assembly includes a connecting shaft 15 coaxially fixed on the output end of the first motor 4, and the other end of the connecting shaft 15 is coaxially fixedly connected to the power input end of the screw lift 3; a ratchet 16 is coaxially fixedly connected to the connecting shaft 15, and an outer rod 17 is fixedly connected to the side of the vertical plate 11 close to the first motor 4, and an inner rod 18 is slidably matched in the outer rod 17, one end of the inner rod 18 extends out of the outer rod 17 and its end is fixedly connected to a limit block 19, the cross-section of the limit block 19 is set to a right-angle trapezoid, the limit block 19 is engaged with the tooth groove of the ratchet 16, and a tension spring 20 is installed between the other end of the inner rod 18 and the inner wall of the outer rod 17; when the limit block 19 is engaged with the tooth groove of the ratchet 16, the connecting shaft 15 can only rotate in the reverse direction, that is, the output end of the first motor 4 can only rotate in the reverse direction, thereby realizing the one-way locking of the first motor 4.

[0041] like Figure 4 and Figure 8 As shown, an inclined groove 21 is provided on the side of the inner rod 18 close to the trigger rod 5, and a block 22 is fixedly connected to the trigger rod 5, and the inclined groove 21 and the block 22 are slidably matched; when the trigger rod 5 rises relative to the cross plate 12, the block 22 slides in the inclined groove 21 and drives the inner rod 18 to be pulled out of the outer rod 17, and the limit block 19 follows the movement of the inner rod 18 and engages with the tooth groove of the ratchet 16.

[0042] like Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the second limit assembly includes a guide groove 23 arranged on the vertical plate 11, a guide block 24 is slidably fitted in the guide groove 23, one side of the guide block 24 is rotatably connected to a rotating shaft 25, the other end of the rotating shaft 25 is coaxially provided with a one-way bearing 27, and a gear 26 is coaxially provided on the one-way bearing 27. The gear 26 can only rotate to one side relative to the one-way bearing 27 (the direction of rotation to this side is set as the positive rotation direction); a tooth portion 33 is provided on the trigger rod 5, and the gear 26 is meshed and connected with the tooth portion 33. A torsion spring 28 is sleeved on the rotating shaft 25 between the gears 26 and the trigger rod 5; when the gear 26 is meshed with the tooth portion 33 and the trigger rod 5 rises relative to the cross plate 12, the tooth portion 33 drives the gear 26 to rotate in the forward direction. At this time, the one-way bearing 27 will not affect the rotation of the gear 26; it should be noted that, by using the matching arrangement of the one-way bearing 27 and the torsion spring 28, it is difficult for the gear 26 to rotate in the reverse direction (the reverse rotation of the gear 26 needs to overcome the resistance of the torsion spring 28), thereby preventing the trigger rod 5 from falling autonomously due to the restoring force of the tension spring 20 after movement, thereby achieving the limit of the trigger rod 5.

[0043] A compression spring 29 is installed in the guide groove 23 on the side of the guide block 24 close to the vertical plate 11. In the initial state, the compression spring 29 is in the expanded state and presses against the guide block 24, so that the gear 26 engages with the tooth portion 33; a pull rod 30 is slidably connected through the vertical plate 11, and one end of the pull rod 30 is fixedly connected to the guide block 24; when the pull rod 30 is pulled, the guide block 24 slides in the guide groove 23 and drives the gear 26 away from the tooth portion 33, thereby releasing the limit on the trigger rod 5.

[0044] like Figure 3 and Figure 7 As shown, a through groove is opened on the horizontal plate 12, and the through groove and the trigger rod 5 are slidably matched. The bottom end of the trigger rod 5 is rotatably connected with an induction wheel 31, and a rotation sensor 32 is installed on the induction wheel 31. The first motor 4 is electrically connected to the rotation sensor 32; it should be noted that the control system is electrically connected to the rotation sensor 32. When the induction wheel 31 rotates, the rotation sensor 32 transmits a signal to the control system, and the control system controls the first motor 4 to start and rotate in the reverse direction.

[0045] like Figure 1 and Figure 2 As shown, it also includes a machine tool 2, on which a transverse electric guide rail 34 is provided, and a trolley transverse plate 35 is installed on the driving part of the transverse electric guide rail 34. The transverse electric guide rail 34 can drive the trolley transverse plate 35 to move transversely, thereby realizing the transverse displacement of the nozzle.

[0046] like Figure 1 and Figure 2 As shown, a second motor 36 is installed on the trolley fixing frame 1, and the output end of the second motor 36 is set upward, and the output end of the second motor 36 is fixedly connected to the trolley transverse plate 35; a first pressure sensor 37 and a second pressure sensor 38 are provided on the trolley transverse plate 35, and the second motor 36, the first pressure sensor 37 and the second pressure sensor 38 are all electrically connected to the control system; the first pressure sensor 37 and the second pressure sensor 38 are both electrically connected to the second motor 36; a trigger block 39 is fixedly connected to the top of the trolley fixing frame 1, and the setting positions of the first pressure sensor 37 and the second pressure sensor 38 are matched with the trigger block 39, and when the trigger block 39 hits any one of the first pressure sensor 37 and the second pressure sensor 38, the second motor 36 stops rotating.

[0047] like Figure 1 and Figure 2The device is in scanning mode, at which time the trigger block 39 abuts against the second pressure sensor 38. When the device needs to switch to the direct-output mode, the second motor 36 is started, and the second motor 36 drives the trolley fixing frame 1 to rotate. At the same time, the trigger block 39 is away from the second pressure sensor 38, and the nozzle position is adjusted. When the trigger block 39 moves to abut against the first pressure sensor 37 (in this embodiment, the angle at which the trolley fixing frame 1 can rotate is set to 90 degrees, that is, the trigger block 39 abuts against the first pressure sensor 37 when it rotates 90 degrees), the first pressure sensor 37 transmits a signal to the control system, and the control system controls the second motor 36 to stop rotating, thereby realizing the switching between the scanning mode and the direct-output mode of the device.

[0048] When the device is used, the first motor 4 is started and rotated forward, the connecting shaft 15 rotates forward and drives the screw lift 3, so that the vertical plate 11 moves away from the trolley fixing frame 1, that is, the vertical plate 11 and the horizontal plate 12 move downward, and the nozzle approaches the cardboard on the machine tool 2. It should be noted that the nozzle needs to be lowered to a different distance depending on the specifications of the cardboard. When the horizontal plate 12 is lowered to the point where the trigger rod 5 touches the cardboard below, the trigger rod 5 rises relative to the horizontal plate 12, proving that the horizontal plate 12 has dropped excessively.

[0049] When the trigger rod 5 rises relative to the cross plate 12, the block 22 slides in the inclined slide groove 21 and drives the inner rod 18 to be pulled out from the outer rod 17. At the same time, the tension spring 20 is stretched to store force, and the limit block 19 follows the movement of the inner rod 18 and engages with the tooth groove of the ratchet 16. At this time, the connecting shaft 15 can only rotate in the opposite direction, thereby realizing a one-way locking of the first motor 4, that is, the cross plate 12 and the nozzle can no longer descend, thereby avoiding excessive descent resulting in poor printing quality or even damage to the device; after the output end of the first motor 4 is locked, the first motor 4 will be automatically shut down through the setting of the stall protector, thereby realizing automatic stopping of the first motor 4.

[0050] It should be noted that, in the initial state, the first electrode block 6 is in contact with the third electrode block 8, that is, the second indicator light 10 emits green light, and the device is in a normal working state at this time; when the horizontal plate 12 drops excessively and causes the trigger rod 5 to rise relative to the horizontal plate 12, the first electrode block 6 rises relative to the horizontal plate 12 and no longer contacts the third electrode block 8, and the first electrode block 6 contacts the second electrode block 7. At this time, the first indicator light 9 emits red light to remind the staff, proving that the device is in an abnormal working state at this time.

[0051] Then, by controlling the first motor 4 to rotate in the opposite direction, the position of the horizontal plate 12 is finely adjusted to make the nozzle rise, so that the distance between the nozzle and the paperboard reaches the expected value, thereby ensuring the printing effect of the device; then the pull rod 30 is pulled, the guide block 24 slides in the guide groove 23 and drives the gear 26 away from the tooth portion 33, thereby releasing the limit on the trigger rod 5, and the tension spring 20 releases the force to pull the inner rod 18 back into the outer rod 17, so that the limit block 19 is disengaged from the tooth groove of the ratchet 16, thereby releasing the one-way lock on the output end of the first motor 4; at the same time, the block 22 slides in the opposite direction in the inclined slide groove 21 and causes the trigger rod 5 to descend and reset, the first electrode block 6 descends and contacts the third electrode block 8 again, the second indicator light 10 emits green light, and the light indication on the device returns to a normal working state.

[0052] It should be noted that when the device is printing, affected by factors such as operational errors, if the transverse plate 12 drops excessively (at this time, the induction wheel 31 is against the cardboard) and the transverse plate 12 moves horizontally relative to the cardboard (for example, the device is in the straight-out mode, the conveyor belt on the device rolls to move the cardboard, or the device is in the scanning mode, the transverse electric guide rail 34 drives the transverse plate 12 and the nozzle to move horizontally), the induction wheel 31 rotates, and the rotation sensor 32 transmits a signal to the control system. The control system controls the first motor 4 to start and rotate in the opposite direction, so that the transverse plate 12, the induction wheel 31 and the nozzle automatically rise, thereby avoiding the cardboard, thereby realizing the automatic risk avoidance function of the device.

[0053] It is worth noting that when the first motor 4 rotates in the reverse direction, the connecting shaft 15 moves in the reverse direction with the ratchet 16. Since the cross-section of the limit block 19 is set to a right-angled trapezoid, during the reverse rotation of the ratchet 16, when the tooth groove wall of the ratchet 16 hits the inclined surface of the limit block 19, the inner rod 18 is retracted into the outer rod 17, and at the same time, the trigger rod 5 descends to make the gear 26 rotate in the reverse direction with the one-way bearing 27, and the torsion spring 28 deforms and accumulates force; when the ratchet 16 rotates to the next tooth groove of the ratchet 16 corresponding to the limit block 19, the torsion spring 28 releases the force to make the gear 26 and the one-way bearing 27 rotate forward to reset, the trigger rod 5 rises and drives the inner rod 18 to be pulled out from the outer rod 17, and the limit block 19 automatically snaps into the next tooth groove of the ratchet 16; during the reverse rotation of the first motor 4, the trigger rod 5 performs reciprocating lifting and lowering motion.

[0054] During the reciprocating lifting and lowering movement of the trigger rod 5, the first electrode block 6 reciprocates and rises and falls and intermittently contacts the second electrode block 7 or the third electrode block 8, causing the first indicator light 9 and the second indicator light 10 to switch and flash, that is, during the automatic risk avoidance working process of the device, the red light and the green light are switched and flashed, thereby alerting the staff that the device is in the automatic risk avoidance state and reminding the staff to take corresponding treatment measures later.
