DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0025] Embodiment 1

[0026] like Figures 1 to 5As shown, an adjustable synchronous inkjet printer includes a conveyor belt 1 and a spray terminal 2 installed above the conveyor belt 1, a synchronization mechanism is arranged on the conveyor belt 1, an infrared sensor 3 is arranged between the synchronization mechanism and the spray terminal 2, the synchronization mechanism includes a synchronizer 4 and a rubber pressure wheel 5, the rubber pressure wheel 5 is installed at the input end of the synchronizer 4, the rubber pressure wheel 5 contacts the conveying surface of the conveyor belt 1, the driving shaft 8 of the conveyor belt 1 is connected to a speed change driving mechanism, the speed change driving mechanism includes a motor 6 and a gearbox 7, the output shaft of the motor 6 is connected to the power input shaft of the gearbox 7, the power output shaft of the gearbox 7 is connected to a driving disk 9, and the driving disk 9 A plurality of driving teeth 10 are fixed to the end surface close to the driving shaft 8, and the plurality of driving teeth 10 are evenly distributed along the circumferential direction of the driving disk 9, and a first tooth groove is formed between two adjacent driving teeth 10. A driven disk 11 is slidably mounted on the driving shaft 8, and a plurality of driven teeth 12 are fixed to one end of the driven disk 11 close to the driving disk 9, and the plurality of driven teeth 12 are evenly distributed along the circumferential direction of the driven disk 11, and a second tooth groove is formed between two adjacent driven teeth 12. The driving teeth 10 are meshed and matched in the second tooth groove, and the driven teeth 12 are meshed and matched in the first tooth groove; when the infrared sensor 3 detects the product, the speed change drive mechanism drives the conveyor belt 1 to run at a low speed;When the product moves to the coding position, the motor 6 stops, and the driven disc 11 moves and separates from the active disc 9, and the conveyor belt 1 runs to send the product to the position of the coding terminal 2 for coding operation. The coding terminal 2 is connected to the coding machine. This belongs to the prior art and will not be repeated. The conveyor belt 1 will drive the rubber pressure wheel 5 to rotate when it is running. Since the rubber pressure wheel 5 is connected to the synchronizer 4, the synchronizer 4 can identify the speed of the rubber pressure wheel 5, thereby obtaining the actual running speed of the conveyor belt 1, and then obtaining the moving speed of the product. The synchronizer 4 feeds back the identified speed to the coding machine, and identifies the position of the product through the infrared sensor 3. When the infrared sensor 3 detects the product, the delayed coding time of the inkjet terminal 2 can be controlled in combination with the moving speed of the product. Since the size of the product is known and the position of the coding position on the product is also known, the timing starts when the infrared sensor 3 detects the product. In combination with the running speed of the product at this time, the action time of the inkjet terminal 2 can be obtained. When coding, the conveyor belt 1 stops running, the product stops, and the inkjet terminal 2 moves to code the coding position of the product, thereby accurately coding the coding position, improving the coding accuracy and coding effect, and greatly reducing the number of defective coding products. In order to further improve the accuracy of coding, the running speed of the conveyor belt 1 is adjusted. The gearbox 7 is driven by the motor 6 to run. The gearbox 7 drives the driving shaft 8 to rotate through the engagement of the driving disk 9 and the driven disk 11. The driving shaft 8 drives the conveyor belt 1 to run. The transmission speed of the conveyor belt 1 can be adjusted by the gearbox 7. When the product has not entered the detection range of the infrared sensor 3, the running speed of the conveyor belt 1 is relatively high, and the product can be quickly transported to the coding position. When the infrared sensor 3 detects the product, the speed of the gearbox 7 is adjusted to make the conveyor belt 1 run at a low speed, so that the product approaches the coding position at a low speed. The inkjet station 2 moves to reduce the inertia error after the conveyor belt 1 stops. When the product runs to the inkjet position, the motor 6 stops to stop the conveyor belt 1. Due to the low-speed operation of the conveyor belt 1, the conveyor belt 1 can be stopped in time, reducing the inertia of the conveyor belt 1 after stopping, and further improving the inkjet accuracy. In specific implementation, the product moves on the conveyor belt 1 by limiting the position to ensure that there is no deviation during the movement, that is, two sets of limit plates are set along the width direction of the conveyor belt 1, and the product moves between the two sets of limit plates to avoid product movement deviation affecting the inkjet effect. ;

[0027] Embodiment 2

[0028] Based on the first embodiment, Figure 1 and Figure 4As shown, the inkjet terminal 2 is installed on the inkjet printer frame 31, and a lifting beam 32 is provided on the inkjet printer frame 31. The lifting beam 32 moves along the height direction of the inkjet printer frame 31. A translation seat 33 is slidably provided on the lifting beam 32. The translation seat 33 moves along the conveying direction perpendicular to the conveyor belt 1. The side wall of the translation seat 33 is spherically hinged with an angle adjustment plate 34. The inkjet terminal 2 is installed on the angle adjustment plate 34. The inkjet height of the inkjet terminal 2 is adjusted by the movement of the lifting beam 32, so that it is convenient to select a suitable inkjet height according to the height of the product. The inkjet terminal 2 is driven by the translation seat 33 to move along the width direction of the conveyor belt 1 to adjust the inkjet position to adapt to the inkjet position of the product, so as to meet the inkjet requirements of various different products. Secondly, the inkjet position of some products is not horizontal, and there will be a need for inkjet printing on an inclined surface. The inkjet angle of the inkjet terminal 2 can be adjusted by the angle adjustment plate 34, so as to meet the requirements of inkjet printing at an inclined position, thereby further improving the inkjet range.

[0029] Furthermore, a lifting cylinder 35 is vertically installed on the inkjet printer frame 31, and the telescopic shaft of the lifting cylinder 35 is connected to the lifting beam 32. A linear drive module is installed on the lifting beam 32, and the translation seat 33 is installed on the sliding seat of the linear drive module. The lifting beam 32 is driven up and down by the telescopic movement of the lifting cylinder 35, thereby adjusting the inkjet height of the inkjet terminal 2, and the translation seat 3 is driven to do linear motion by the linear drive module to adjust the inkjet position of the inkjet terminal 2.

[0030] Embodiment 3

[0031] Based on the second embodiment, Figure 4 As shown, a ball rod 36 is fixed to the end face of the angle adjustment plate 34 close to the translation seat 33, and the ball rod 36 is perpendicular to the angle adjustment plate 34. A ball joint 37 is fixed to the end of the ball rod 36 away from the angle adjustment plate 34. A ball joint groove is provided on the translation seat 33, and the ball joint 37 is spherically hinged in the ball joint groove. A fastening bolt 38 is threadedly connected to the side wall of the translation seat 33, and the tail of the fastening bolt 38 is inserted into the ball joint groove to abut the ball joint 37. The coding angle of the inkjet terminal 2 is manually adjusted. The fastening bolt 38 is loosened during adjustment. Since the ball joint 37 is spherically hinged in the ball joint groove, the angle adjustment plate 34 can be deflected in any direction, with a larger adjustment range and a wider adaptability. When the angle adjustment of the inkjet terminal 2 is completed, the fastening bolt 38 is tightened to abut the ball joint 37 to lock the angle adjustment plate 34, thereby completing the coding angle adjustment.

[0032] Embodiment 4

[0033] Based on the third embodiment, Figures 1 to 3As shown, the side wall of the driving shaft 8 is provided with a plurality of spline grooves 14 along its circumferential direction, and a sliding tooth is fixed at the position corresponding to the spline groove 14 on the inner wall of the driven disc 11, and the sliding tooth is slidably adapted in the spline groove 14, and a spring 13 is arranged in the spline groove 14, and the two ends of the spring 13 are respectively connected to the driving shaft 8 and the driven disc 11, when the driving disc 9 is in transmission engagement with the driven disc 11, the spring 13 is in a compressed state, and a locking mechanism is arranged on the frame of the conveyor belt 1, and the locking mechanism includes a tooling plate 1 5. The left clamp block 16 and the right clamp block 17, the tooling plate 15 is installed on the frame of the conveyor 1 by bolts, the left clamp block 16 and the right clamp block 17 are distributed on both sides of the driving shaft 8, the left clamp block 16 and the right clamp block 17 are slidably set on the top of the tooling plate 15, the end surface of the left clamp block 16 close to the driving shaft 8 and the end surface of the right clamp block 17 close to the driving shaft 8 are provided with a clamping groove 18, and a friction plate 19 is fixed in the clamping groove 18. When the product runs to the coding position, the motor 6 stops. At the same time, the locking mechanism is actuated, and the left clamp block 16 and the right clamp block 17 move close to the driving shaft 8 at the same time, so that the friction plate 19 is pressed against the driving shaft 8, thereby locking the driving shaft 8 through the cooperation of the left clamp block 16 and the right clamp block 17. Therefore, after the motor 6 stops, the rotational inertia of the driving shaft 8 can be limited in time, further improving the inkjet effect. Secondly, since the motor 6 has rotational inertia after stopping, in order to avoid the rotational inertia of the motor 6 affecting the driving shaft 8, and the locking of the driving shaft 8 affecting the motor 6, the driven disk 11 has the freedom to move along the axial direction of the driving shaft 8. At the same time, the driving teeth 10 and the driven teeth 12 are both wedge-shaped teeth, and the inclined surfaces of the driving teeth 10 and the driven teeth 12 do not match, so that when the driving teeth 10 squeeze the driven teeth 12, force decomposition will occur, so that the driven disk 11 compresses the spring 13 and moves away from the driving disk 9, so that the driving teeth 10 are separated from the driven teeth 12, so that the rotational inertia of the motor 6 after stopping is gradually released, and will not affect the driving shaft 8.

[0034] Furthermore, if Figure 5As shown, a driving cavity 20 is provided in the tooling plate 15, and a strip-shaped slot connected to the driving cavity 20 is provided on the top surface of the tooling plate 15. A first rack 21 and a second rack 22 are arranged opposite to each other in the driving cavity 20. One end of the left clamping block 16 penetrates from the strip-shaped slot to connect the first rack 21, and one end of the right clamping block 17 penetrates from the strip-shaped slot to connect the second rack 22. A gear 23 is provided between the first rack 21 and the second rack 22. The gear 23 is rotatably connected to the tooling plate 15 through a driving shaft 24. The first rack 21 and the second rack 22 are both meshed with the gear 23. One end of the driving shaft 24 penetrates out of the tooling plate 15. The plate 15 is connected with a driving disk 25, and the driving disk 25 is eccentrically hinged to the telescopic shaft of the cylinder 26. The cylinder body of the cylinder 26 is hinged on the tooling plate 15. The cylinder 26 is telescopic to drive the driving disk 25 to deflect. The driving disk 25 drives the gear 23 to rotate through the driving shaft 24. The gear 23 drives the first rack 21 and the second rack 22 to move at the same time. Since the first rack 21 and the second rack 22 are arranged opposite to each other, the moving direction of the left clamping block 16 is opposite to that of the right clamping block 17, so that both the left clamping block 16 and the right clamping block 17 can move close to the driving shaft 8 to lock the driving shaft 8, thereby improving the coding accuracy.

[0035] Embodiment 5

[0036] Based on the fourth embodiment, Figure 1 and Figure 2 As shown, the synchronization mechanism also includes a mounting frame 27 and a hinged plate 28. The mounting frame 27 is connected to the frame of the conveyor belt by bolts. A screw rod 29 is fixed on the hinged plate 28. The screw rod 29 is movably arranged on the mounting frame 27. A nut 30 is threadedly sleeved on the screw rod 29. A synchronization shaft is rotatably connected to the hinged plate 28 through a bearing. One end of the synchronization shaft is connected to the rubber pressure wheel 5, and the other end is connected to the input end of the synchronizer 4. Loosening the nut 30 allows the hinged plate 28 to deflect along the axis of the screw rod 29, adjusting the position of the rubber pressure wheel 5 so that the rubber pressure wheel 5 contacts the conveying surface of the conveyor belt 1, and then tightening the nut 30 to stabilize the position of the rubber pressure wheel 5, so that the conveyor belt 1 can smoothly drive the rubber pressure wheel 5 to rotate, so as to identify the actual conveying speed of the conveyor belt 1, thereby accurately calculating the time for the product's coding position to move to the working position of the inkjet terminal 2, and achieving accurate coding.
