Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, a printer with peelable label paper includes a body 100. A housing 101 is mounted on the outer surface of the body 100. A recess 102 is provided on the surface of the housing 101. A flip cover 106 is rotatably mounted inside the recess 102 via a rotating shaft 105. A pressure roller 107 is rotatably mounted between the inner walls of the two sides of the flip cover 106. A drive roller 104 is mounted inside the body 100 via a drive device 103, and the drive roller 104 is in contact with the outer surface of the pressure roller 107. A peeling plate 108 is installed between the inner walls of the two sides of the body 100, and the peeling plate 108 is positioned above the flip cover 106. Insertion holes are provided on both inner walls of the recess 102, and insertion mechanisms 200 are provided on both sides of the flip cover 106, which are engaged with the insertion holes.

[0026] In use, first open the cover 106, at this time the cover 106 drives the compression roller 107 to separate from the drive roller 104, then tear the part of the label at the front end of the label paper from the base paper, then pass the end from above the drive roller 104, pass through the compression roller 107 and the drive roller 104 from the end of the stripping plate 108, finally extend from the outlet below the recess 102, finally close the cover 106 and fix it through the plug-in mechanism 200, at this time the compression roller 107 can compress the label paper on the drive roller 104, when the drive roller 104 is driven to rotate by the driving device 103, it can drive the compression roller 107 to rotate and drive the label paper to convey through the friction force.

[0027] Since the label paper passes around the end of the stripping plate 108 with a large angle change, and the label has a larger deformation ability than the base paper, when the base paper passes around the end of the stripping plate 108, the label cannot follow the base paper to bend and deform at a large angle, so it is lifted to achieve the purpose of separating from the base paper.

[0028] Since the friction force exerted by the compression roller 107 and the drive roller 104 on the label paper is improved, the stable conveying of the label paper is ensured, and the situation that the label paper slips or deviates during conveying is avoided, the position accuracy of printing and the peeling effect of the label and the base paper are improved.

[0029] Preferably, the plug-in mechanism 200 comprises a fixed block 201 installed on the inner side of the cover 106 and close to the length direction edge thereof, a sliding groove 202 is formed on the surface of the fixed block 201, a sliding block 203 is slidably installed in the sliding groove 202, a plug rod 204 and a pressing block 205 are respectively installed on the outer surface of the sliding block 203, the end portions of the plug rod 204 and the pressing block 205 penetrate to the outside of the cover 106, and the plug rod 204 is matched with the insertion hole.

[0030] By pressing the pressing block 205 to drive the sliding block 203 to slide in the sliding groove 202, the plug rod 204 can be retracted, when it is needed to open the cover 106, the plug rod 204 can be pulled out of the insertion hole by pressing the pressing block 205, then the cover 106 can be opened by rotating it, in the process of opening the cover 106, the plug rod 204 can increase the resistance when the cover 106 is opened under the action of the elastic force of the spring 206, thereby reducing the opening speed of the cover 106, cooperating with the limiting effect of the limiting stopper 400, further reducing the impact force when the cover 106 contacts the limiting stopper 400, and since the opening angle of the cover 106 is limited by the limiting stopper 400, it is ensured that when the cover 106 is opened to the maximum, the end portion of the plug rod 204 is still in abutment with the inner wall of the recess 102, avoiding separation.

[0031] When the cover 106 is closed, it only needs to be pushed to flip, and when the plug rod 204 is repositioned to the plug hole position, it can be inserted into its interior under the push of the spring 206, achieving the purpose of automatic fixation and improving the portability of operation.

[0032] Preferably, a peeling sensor 300 is installed at the middle position of the inner side surface of the cover 106, and the peeling sensor 300 is electrically connected to the driving device 103. A through hole 301 is formed on the surface of the cover 106 corresponding to the peeling sensor 300.

[0033] When the label is separated from the base paper and extends outward from the upper side of the peeling plate 108, the label blocks the peeling sensor 300. When the user takes away the label, the blocking of the peeling sensor 300 disappears. At this time, the peeling sensor 300 sends a signal to the driving device 103, and the peeling sensor 300 drives the driving roller 104 to rotate again, separates the next label from the base paper and extends outward, thereby achieving the purpose of automatic label supply and improving work efficiency and use experience.

[0034] Preferably, a limiting block 400 is installed on both sides of the inner wall of the recess 102, and a rubber pad is arranged at the end of the limiting block 400.

[0035] After the cover 106 is opened to a certain angle, the cover 106 comes into contact with the rubber pad on the end of the limiting block 400, which can play a buffering role. In addition, the limiting block 400 also limits the opening angle of the cover 106, reduces the speed accumulation when it is opened, thereby reducing the impact force received by the cover 106 and reducing the vibration damage to other components caused by the impact.

[0036] Preferably, a limiting column 500 is installed on the outer surface of the sliding block 203, and the spring 206 is sleeved on the outer surface of the limiting column 500.

[0037] Through the arrangement of the limiting column 500, the guiding effect of the spring 206 can be improved to avoid the bending deformation of the spring 206 during use.

[0038] Preferably, a reinforcing rib 600 is uniformly arranged on the outer surface of the cover 106 along the length direction thereof.

[0039] Through the arrangement of the reinforcing rib 600, the overall structural strength of the cover 106 is strengthened, which can withstand greater external force and prolong the service life.

[0040] Preferably, a tempered glass is arranged in the through hole 301.

[0041] The tempered glass does not affect the monitoring of the peeling sensor 300, and the tempered glass can prevent foreign matter and dust from entering the through hole 301 to affect the peeling sensor 300, thereby improving the protection effect of the peeling sensor 300.
