Detailed Description
The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Example one
The embodiment provides a digital printing machine, as shown in fig. 1-4, the digital printing machine comprises a frame 100 and a tensioning mechanism, the tensioning mechanism comprises a tensioning roller 200 and an adjusting member, the adjusting member is provided with a guiding structure, the end part of the tensioning roller 200 is arranged on the guiding structure and can move along a wire structure, and the adjusting member is arranged on the frame 100 and can adjust the included angle of the guiding structure relative to the horizontal plane. The tensioning roller 200 moves along the guide structure under the action of gravity, when the included angle between the guide structure and the horizontal plane is larger, the component force of the gravity on the moving direction of the tensioning roller 200 is larger, the tensioning force is larger, and when the included angle between the guide structure and the horizontal plane reaches 90 degrees, the tensioning roller 200 vertically moves, and the tensioning force is the largest at the moment. For thicker media, the included angle between the guide structure and the horizontal plane can be increased to increase the tension force and improve the tension effect; for thinner media, the included angle between the guide structure and the horizontal plane can be reduced to reduce the tension force, and the medium can be prevented from being damaged due to overlarge tension force. Through the adjusting part, the included angle between the guide structure and the horizontal plane can be adjusted, so that the tension adjusting function is realized, and the device is suitable for media with different thicknesses or materials.
The adjustment member may be an assembly or may be a separate component. The adjusting member in this embodiment is a single component, i.e. the adjusting plate 300, i.e. the tension can be adjusted only by the adjusting plate 300, and the plate-shaped adjusting member has a simple and firm structure, and is convenient for stable installation with the frame 100. Of course, as other embodiments, the adjusting member may be a rod-shaped structure, a frame-shaped structure, or the like.
The adjusting plate 300 has a hinge hole 310 and an adjusting hole 320, the adjusting hole 320 is an arc-shaped hole, and the adjusting plate 300 can be angularly adjusted by making the hinge hole 310 circular. The hinge hole 310 may be located above or below the adjustment hole 320, and the shape of the hinge hole 310 is not limited, and may be a circular hole shape, a strip shape, or the same shape as the adjustment hole 320. The adjusting hole 320 is generally an arc-shaped hole so as to adjust the rotation of the adjusting plate 300, and the adjusting plate can still be fixed to the frame 100 by screws. Of course, the adjusting holes 320 may also be disposed on the frame 100, for example, the frame 100 is a wall-panel frame 100, the adjusting holes 320 may be disposed on the wall panel, and the adjusting plate 300 only needs to be disposed with fixing holes corresponding to the adjusting holes 320 on the wall panel. In addition, instead of the adjusting hole 320, for example, the adjusting plate 300 may be hinged to the frame 100, and after the adjusting plate 300 is adjusted to the proper position, the adjusting plate 300 may be supported by a telescopic rod to fix the position of the adjusting plate 300.
The guide structure is located on the adjusting plate 300 and is a guide hole 330, so that the structure is simple and the processing is convenient. When the guide structure may be a guide groove, the guide structure provides a moving path for the tension roller 200, and adjusting the inclination of the guide structure adjusts the moving direction of the tension roller 200, so that the component force of gravity in the moving direction is changed.
As shown in fig. 1 and 4, the tension roller 200 includes a roller body 210 and a connecting shaft 220 located at two ends of the roller body 210, the connecting shaft 220 has a protruding limiting portion 230, the limiting portion 230 is located in a guide hole 330, and an inner side surface of the adjusting plate 300 has a limiting member capable of limiting the limiting portion 230 to separate from the guide hole 330 toward the inner side of the adjusting plate 300. The limiting members are disposed on the adjusting plates 300 at two ends of the tensioning roller 200, so that the roller body 210 is prevented from contacting the adjusting plate 300 and being blocked from rotating while the tensioning roller 200 is prevented from automatically separating from the adjusting plate 300. The stopper 230 may be integrated with the connecting shaft 220, or may be a bearing that is subsequently mounted on the connecting shaft 220. In addition, the limiting member may be disposed outside the adjusting plate 300, and may also perform a limiting function.
The limiting member includes a first limiting plate 340 and a second limiting plate 350, the first limiting plate 340 and the second limiting plate 350 are respectively disposed at two side edges of the guiding hole 330, and the first limiting plate 340 and the second limiting plate 350 are detachably fixed on the adjusting plate 300 by screws. This symmetrically limits the limit portion 230, thereby improving the stability of the movement of the tension roller 200.
An object sensor 360 is arranged on the adjusting plate 300, and the object sensor 360 is connected with a controller on the digital printing machine. The movement of the tension roller 200 is sensed by the object sensor 360 to control the winding speed of the wind-up roller 400. The object sensor 360 includes at least a first sensor 361 and a second sensor 362, and the tension roller 200 normally moves between the first sensor 361 and the second sensor 362. If the tension roller 200 moves between the first sensor 361 and the second sensor 362, the winding speed is matched with the rubber roller feeding speed, and the first sensor 361 and the second sensor 362 cannot detect an object, so that the controller cannot be in a state of judging the position of the tension roller 200 for a long time, and the calculation amount of the controller is reduced. The first sensor 361 is positioned above the second sensor 362, when the first sensor 361 detects the tension roller 200, the winding speed of the winding roller 400 is larger than the feeding speed of the rubber roller, and the winding speed is reduced by the controller; when the second sensor 362 detects the tension roller 200, it indicates that the feeding speed of the rubber roller is greater than the winding speed of the winding roller 400, and the winding speed is increased by the controller. This prevents the tension roller 200 from moving to the extreme position of the adjustment structure and losing tension.
The first stopper plate 340 has a boss 341 protruding inward, and the object sensor 360 is fixed to the boss 341. Thus, when the position of the object sensor 360 is adjusted, the object sensor does not interfere with the nut 342 of the screw for fixing the first stopper plate 340.
The digital printing machine comprises a spray printing platform 500, wherein a tensioning mechanism is arranged at the downstream of the spray printing platform 500 and is positioned before media are dried. The medium after spouting the seal is in the moist state, and the medium of moist state is comparatively sensitive to the tensioning force, and adjustable straining device is located the tensioning that can better adapt to the medium after spouting the seal platform 500 downstream.
Example two
The difference between this embodiment and the first embodiment is mainly the position sensing means of the guide structure and the tension roller 200.
The adjusting member of the present embodiment is formed as an assembly, that is, the guide structure is formed using other components mounted on the adjusting plate 300, not directly formed on the adjusting plate 300. Specifically, the guide structure includes a first guide frame 610 and a second guide frame 620, each of the first guide frame 610 and the second guide frame 620 has a guide groove 630, both ends of the tension roller 200 are respectively inserted into the guide grooves 630 of the first guide frame 610 and the second guide frame 620, and both ends of the tension roller 200 move along the guide grooves 630. The two side walls of the guide groove 630 which restrain the tension roller 200 are flat. The two side walls are planes instead of step surfaces or tooth surfaces, so that the tension roller 200 can swing left and right conveniently, the left and right swinging is usually slight, and the condition that the tightness of the jet printing media at the two ends of the tension roller 200 is inconsistent can be avoided. In addition, the guide frame may be directly hinged to the frame 100 without the adjustment plate 300.
The guide groove 630 is upwardly penetrated through the first guide frame 610 and the second guide frame 620 to form an installation opening 640, and a cover plate is disposed at the installation opening 640. The apron can prevent that tensioning roller 200 from breaking away from installing port 640, dismantles the apron back, and tensioning roller 200 just can realize the dismouting from installing port 640.
The sensor for detecting the state of the tension roller 200 in this embodiment is a distance sensor 650, and specifically, the digital printing machine includes a controller and the distance sensor 650 capable of detecting the position of the tension roller 200, and the controller is connected to the distance sensor 650. When the distance sensor 650 detects that the tensioning roller 200 is higher than the preset highest position, the controller controls the unwinding roller to accelerate the unwinding speed; when the distance sensor 650 detects that the tension roller 200 is lower than the preset minimum height, the controller controls the unwinding speed of the unwinding roller to reduce the unwinding speed, so as to prevent the tension roller 200 from being too high or too low to lose the tensioning effect.
