Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printers, in particular to an inkjet printer mechanism with a nozzle anti-blocking mechanism. Background Art

[0002] The inkjet printer is a device used to print and print products. It is usually used to print information such as production date, batch number, barcode, etc. on the packaging. The inkjet printer can be adjusted as needed to adapt to different products and production environments. The inkjet printer usually uses inkjet technology or laser technology to print, which can achieve high-speed, efficient and clear printing effects.

[0003] At present, when most of the existing coding mechanisms are coding on items that need to be coded, the items in the transportation process may collide with the coding connector, thereby causing damage to the coding connector. Since the sizes of the items that need to be coded and the positions of the coding are different, the existing coding mechanisms cannot adjust the position and angle of the coding connector more conveniently. Therefore, the technical personnel in this field provide a coding mechanism with a nozzle anti-blocking mechanism to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a coding mechanism with a nozzle anti-blocking mechanism. By rotating a bidirectional screw at the midpoint of the upper end surface of the base plate, the sliding block arranged by the threaded sleeve can drive the rotating mechanism slidably arranged between the support plates to perform horizontal movement adjustment. At the same time, the rotating mechanism slidably arranged between the support plates can rotate and adjust the coding connector that is fixed and clamped according to needs.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The coding mechanism with a nozzle anti-blocking mechanism comprises a bottom plate and two fixed plates, wherein the upper surface of the bottom plate is fixedly provided with a sliding seat near the front end and the rear end, and the midpoints of the upper surface of the bottom plate on both sides are fixedly provided with a fixed block, and a bidirectional screw is rotatably embedded between the two fixed blocks, and the upper surfaces of the two fixed plates are fixedly provided with a support plate near the front end and the rear end, and a rotating mechanism is movably provided between the two support plates located on the same side of the four support plates;

[0007] The two rotating mechanisms each include a fixed housing, two gears, two first rotating plates, two second rotating plates and two sliding blocks, the upper end surfaces of the two fixed housings are movably embedded with a clamping mechanism, the opposite sides of the two fixed housings are fixedly provided with a baffle mechanism, the two clamping mechanisms each include a clamping plate, a movable rod and a connecting spring, and the two baffle mechanisms each include an anti-blocking housing, two supporting springs, two sliding rods and an anti-blocking plate;

[0008] Through the above technical scheme, the rotatable bidirectional screw can drive the fixed plate set on the outer surface of the sliding seat through the slider to move and adjust, and at the same time, the movement drives the two rotating structures to move horizontally, so that coding operations can be performed on objects of different sizes. At the same time, the clamping structure embedded in the upper end surface of the rotating structure can clamp and fix the rotated coding connector after the rotating mechanism is rotated and adjusted. The fixed baffle mechanism can effectively prevent the coding connector from colliding with the object when the coding connector is coding on the object.

[0009] Further, the two first rotating plates are respectively fixedly arranged on one side of the gear, the two second rotating plates are respectively fixedly arranged on the other side of the gear, the two sliding blocks are respectively fixedly arranged on the side of the two first rotating plates away from the gear, and the two first rotating plates are respectively rotatably embedded at the midpoints of the two sides of the fixed housing;

[0010] Through the above technical solution, the first rotating plate after fixed assembly is rotatably set on both sides of the fixed shell, which can better enable the fixed shell with the inkjet connector to rotate, and the screw rod can also drive the rotating mechanism to perform lifting and adjustment.

[0011] Further, the movable rod is fixedly arranged at the midpoint of the lower end surface of the clamping plate, the clamping plate is embedded at the midpoint of the upper end surface of the fixed shell, the movable rod is movably embedded at the midpoint of the upper end surface of the fixed shell, and the connecting spring is fixedly sleeved on the outer surface of the movable rod located in the fixed shell;

[0012] Through the above technical solution, after the clamping plate is embedded in the upper end surface of the fixed shell, the rotating mechanism can be better clamped and fixed under the action of the connecting spring to prevent the rotating mechanism from rotating again after rotation adjustment.

[0013] Furthermore, the two sides of the clamping plate are respectively engaged with two gears, and screw rods are rotatably arranged at the midpoints of the rear end surfaces of the two support plates located near the front end among the four support plates, and sliding rods are fixedly arranged at the midpoints of the front end surfaces of the two support plates located near the rear end among the four support plates, and the two sliding blocks are respectively sleeved on the outer surfaces of the screw rods and the sliding rods on both sides, and hand wheels are fixedly arranged on the upper end surfaces of the two screw rods;

[0014] Through the above technical solution, the fixed sliding rod can play an auxiliary sliding role when the rotating mechanism is raised and lowered. Turning the handwheel can drive the screw to rotate, and also drive the rotating mechanism of the threaded sleeve to raise and lower, so that coding operations can be performed on objects of different sizes.

[0015] Furthermore, the two sliding rods are respectively fixedly arranged on one side of the baffle plate near the upper end and the lower end, one end of the two movable rods are respectively embedded in the baffle housing near the upper end and the lower end, and the two supporting springs are respectively fixedly arranged on one side of the two sliding rods;

[0016] Through the above technical solution, the support spring fixed at one end of the two movable rods can support the baffle plate. After the baffle plate is attached to the baffle shell, the position of the inkjet coding connector still does not exceed the position of the baffle plate. Therefore, the baffle plate can better protect the inkjet coding connector.

[0017] Furthermore, a coding connector is provided at the midpoint of one side of the fixed shell, and a collecting box is provided on one side of the fixed shell by sliding and embedding at the lower end;

[0018] Through the above technical solution, the coding connector that is snap-fitted can be disassembled and replaced from the fixed shell when replacement is needed, and the collection box that is snap-fitted under the coding connector can collect the inkjet dripping during coding.

[0019] Furthermore, sliding bars are fixedly arranged on the front and rear ends of the lower end surfaces of the two fixed plates, and the two fixed plates are slidably arranged on both sides of the two sliding seats through the sliding bars;

[0020] Through the above technical solution, the fixed sliding bar can make the fixed plate move horizontally on the outer surface of the sliding seat, driving the movable rotating mechanism to change its position.

[0021] Furthermore, a slider is fixedly provided on one side of the lower end surface of the two fixing plates, and the two sliders are respectively threadedly sleeved on both sides of the outer surface of the bidirectional screw, and a rotating wheel is fixedly provided on one end of the bidirectional screw;

[0022] Through the above technical solution, after the slider is threadedly sleeved on the outer surface of the bidirectional screw, the fixed plate can be moved and adjusted by rotating the fixed rotating wheel.

[0023] The utility model has the following beneficial effects:

[0024] 1. The inkjet coding mechanism with a nozzle anti-blocking mechanism proposed by the utility model has a sliding seat fixedly arranged on the upper end surface of the bottom plate near the front end and the rear end. Under the rotation of the rotating bidirectional screw, the fixed plate on which the slider is fixed can be driven to move horizontally on the outer surface of the sliding seat. At the same time, the rotating mechanism slidably arranged between the two supporting plates on the upper end surface of the fixed plate can be moved and adjusted to different positions under the movement of the fixed plate, thereby driving the inkjet coding connector to perform inkjet coding operations on objects of different sizes.

[0025] 2. The inkjet mechanism with a nozzle anti-blocking mechanism proposed in the utility model can be raised and lowered to different heights under the rotation of the screw rod through a rotating mechanism sliding between the two support plates, so that the inkjet connector set in a snap-fitting manner can be used to perform inkjet operation on the conveyed items as required. At the same time, the user can also adjust the inkjet angle of the inkjet connector by rotating the sliding rotating mechanism as required. The snap-fit ​​mechanism embedded in the upper end surface of the rotating mechanism can be snap-fitted and fixed after the rotating mechanism is rotated and adjusted to prevent the rotating mechanism from rotating again. The two fixed baffle mechanisms can effectively prevent the inkjet connector from colliding with the items to be coded during inkjet coding, thereby preventing damage to the inkjet connector.
