Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A printing device for preventing a rubber roller from being wound comprises a printing head 1 for printing characters, a rubber roller 2 for driving consumables to be transmitted and transported, a rubber roller driving device 3 for driving the rubber roller 2 to move, a printing control device 4 for controlling the rubber roller driving device 3 and having a built-in signal calibration function, a reflection type photoelectric sensor 5 for detecting light reflection on the rubber roller 2 and a warning device for providing a warning effect, wherein the reflection type photoelectric sensor 5 and the rubber roller driving device 3 are both electrically connected with the printing control device 4; the reflective photoelectric sensor 5 transmits a detected detection signal to the printing control device 4, the printing control device 4 obtains a threshold value by calibrating the reflective photoelectric sensor 5 on used consumables, and whether winding occurs can be judged by comparing the detection signal of the reflective photoelectric sensor 5 with the threshold value in the printing process. Specifically, the signal calibration function of the printing control device 4 calibrates the detection signal detected by the reflection-type photoelectric sensor 5 with a specific signal intensity threshold value to determine whether the rubber roll 2 is wound with consumables; the reflective photoelectric sensor 5 is arranged on a support piece 6 fixed right below the rubber roller 2, and the reflective photoelectric sensor 5 is detachably connected with the support piece 6.
The working principle of the printing device for preventing the rubber roller from being wound is as follows:
the rubber roller driving device 3 and the reflection type photoelectric sensor 5 are both electrically connected to the printing control device 4, and the reflection type photoelectric sensor 5 is arranged on the paper outlet side of the rubber roller 2. Under the normal printing condition, a gap between the reflective photoelectric sensor 5 and the rubber roller 2 is empty; when the label or the base paper enters the gap, the detection signal generated by the reflective photoelectric sensor 5 changes. The print control device 4 can determine whether there is a winding failure by monitoring the change in the signal intensity of the reflective photoelectric sensor 5. The working principle of the reflection type photoelectric sensor is as follows: the device is provided with a light source and a light receiving device, light emitted by the light source is reflected by an object to be detected and received by a photosensitive element of the light receiving device, and the light is processed by a related circuit to obtain required information. When the winding occurs, the printing control device immediately stops the rubber roller driving device 3. Once the rubber roller 2 stops rotating, winding can only occur within a small range, namely, within the range from the tangent point of the rubber roller 2 and the printing head 1 to the detection point of the reflective photoelectric sensor 5 on the rubber roller 2 from the side view. The included angle A between the two points and the connecting line of the axes of the rubber rollers is less than 180 degrees (figure 2). Therefore, the user can easily pull out the label or the base paper to remove the winding.
The rubber roller 2 is black, and under the normal printing condition, the light reflection amount of the black rubber roller to the reflection type photoelectric sensor 5 is almost 0; when a label or a piece of backing paper enters the gap between the rubber roll 2 and the reflective photoelectric sensor 5, the reflection characteristic of the label or the backing paper to light changes, the light reflection amount of the reflective photoelectric sensor 5 increases, and the signal intensity transmitted to the print controller 4 by the reflective photoelectric sensor 5 changes. The printing control device 4 is provided with a calibration function, and during calibration, a user inserts a label and a piece of backing paper into a gap between the rubber roller 2 and the reflective photoelectric sensor 5 to calibrate the reflective photoelectric sensor 5 to obtain a signal intensity threshold. The print controller 4 sets a default threshold value for the signal intensity of the light sensor 15, and if calibration is not performed, the default threshold value is used. When the user finds that the anti-winding function is invalid, the user firstly considers that the luminosity sensor is calibrated to have a threshold value, the printing control device 4 compares the acquired signal intensity of the luminosity sensor 15 with the threshold value in the printing process, and when the signal intensity exceeds the threshold value, the label or the base paper is determined to enter the gap between the rubber roller 2 and the reflective photoelectric sensor 5. At this time, the print controller 4 stops the printing work, waits for the manual cleaning of the entanglement, and the reflective type photoelectric sensor 5 may be designed to be mechanical.
Embodiment one of the supporting member 6
As shown in fig. 3 and 6, the support 6 is an L-shaped support, the vertical portion is fixed to the printer main body 7, the horizontal portion is parallel to the rubber roller 2, a plurality of (at least three) reflective photoelectric sensors 5 are uniformly distributed on the horizontal portion of the L-shaped support, and each reflective photoelectric sensor 5 is electrically connected to the print control device 4.
Support 6 embodiment two
As shown in fig. 4 and 5, the support member 6 includes an upper flange plate horizontally disposed and a lower flange plate vertically disposed, the upper flange plate is provided with an upper through hole 9 through which light of the reflective photoelectric sensor 5 passes, the lower flange plate is provided with a lower through hole 10 through which the reflective photoelectric sensor 5 is fixed, the reflective photoelectric sensor 5 is fixed on the detector moving bracket 8, and the detector moving bracket 8 is fixed with the lower through hole 10 by a locking screw.
The reflection type photoelectric sensor comprises a light source, a light receiving device and an information processing device, light emitted by the light source is reflected by the rubber roller 2 or the consumable material and received by the light receiving device, and the light receiving device converts received light information into electric information and processes the electric information by the information processing device to obtain required information.
When the detection signal intensity detected by the reflective photoelectric sensor 5 exceeds a specific signal intensity threshold value, the printing control device 4 judges that consumables enter between the rubber roller 2 and the reflective photoelectric sensor, and the printing control device 4 is used for controlling the rubber roller driving device 3 to stop working, wherein when the printing control device 4 judges that the rubber roller 2 winds the consumables, the printing control device 4 controls the rubber roller driving device 3 to stop working, the printing work is stopped, and the manual removal of the wound consumables is waited;
if the printing device is required to automatically try to remove the winding, the printing control device 4 is used for controlling the rubber roll driving device 3 to rotate forwards and reversely, the printing control device 4 controls the rubber roll driving device 3 to drive the rubber roll 2 to rotate backwards by a certain angle each time, the angle can be set to a factory setting value or can be automatically changed by a user in the using process, when the printing control device 4 judges that the rubber roll 2 is wound with consumables, the printing control device 4 controls the rubber roll driving device 3 to drive the rubber roll 2 to rotate forwards for multiple times until the reflective photoelectric sensor 5 does not detect the consumables wound by the rubber roll 2 in the forward rotation process of the rubber roll 2; if the rubber roller 2 still detects the rubber roller 2 winding consumables after rotating reversely for a plurality of times, the warning device provides warning, and the warning device is a buzzer, an LED indicating lamp or an LCD display screen. The rubber roller driving device 3 is manually stopped, the printing operation is stopped, and the winding consumables are waited to be manually cleared.
Considering that the rubber roller is pure black, while the printing consumables are usually made of light-colored paper or synthetic materials, the reflection amount difference of light is very obvious, the threshold value can also be directly given so as to simplify the use of users, namely, the specific signal intensity threshold value is unified to a factory-set value or is changed by the users in the using process.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
