Description

Technical Field

[0001] The utility model relates to the technical field of printer auxiliary devices, in particular to a bottomless paper stacking device. Background Art

[0002] The bottomless paper printer technology is a new printing technology in recent years, which has the advantages of large single paper roll capacity, low single label printing cost, low paper changing frequency, low carbon environmental protection and no waste paper, and is the trend of future green printing.

[0003] Existing printers can print multiple labels at the same time for standby to expand their application scenarios. For example, after the label paper in the express delivery industry is printed, the bottom paper needs to be torn off and then pasted. However, the label paper here is a traditional self-adhesive label, which mostly consists of a face material and a bottom paper. During use, the bottom paper needs to be torn off, and the torn bottom paper has no use value, resulting in waste of resources. In view of this problem, some existing printers can print labels without a bottom paper (with an adhesive layer at the bottom); however, due to the stickiness of the bottom of the bottomless label paper, there is a problem that multiple labels stick together and cannot be used when printed at the same time.

[0004] In some existing industries (such as the logistics industry, etc.), many sticky notes need to be printed and then rewound together, and then when needed, the printed rewound label paper is torn off one by one and pasted on the product. However, the following problems may occur with this rewinding method: First, the bottomless label paper rewound after printing is not easy to tear off; Second, during rewinding, the paper core needs to be kept from offsetting during the winding process. If an offset occurs, it is difficult to continue rewinding; Third, it is difficult to ensure the flatness of the bottomless label paper during the rewinding process, and there may be problems with wrinkles. It is difficult to organize it to be flat during use.

[0005] In view of this, the inventor specifically designed a bottomless paper stacking device, and this case was thus generated. Content of the Utility Model

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0037] Please refer to Figures 1 to 6 , which is a bottomless paper stacking device as the best embodiment of the present utility model, used for stacking the bottomless label paper 01 with adhesive on the back after printing, including a printing device 20, a rotary disk 30, and a stacking mechanism 40. The printing device 20 is used for printing the bottomless label paper 01; the rotary disk 30 is arranged side by side with the printing device 20 for stacking the printed bottomless label paper 01; the stacking mechanism 40 is arranged above the rotary disk 30 and is used for pressing the printed bottomless label paper 01 onto the rotary disk 30. And when the stacking mechanism 40 presses down once, the rotary disk 30 rotates once, and the rotation angle is set according to the actual situation. The bottomless paper stacking device of the present utility model uses the rotary disk 30 in cooperation with the stacking mechanism 40. When the stacking mechanism 40 presses down once, the rotary disk 30 can rotate a certain angle, so that the stacked bottomless label paper 01 is misaligned, which is convenient for subsequent tearing. At the same time, the flat laying of the bottomless label paper 01 is ensured during the stacking process, avoiding wrinkles.

[0038] Specifically, please refer to Figure 1 , the stacking device further includes a first base 10. The printing device 20 is arranged on the first base 10, and the rotary disk 30 is arranged on the first base 10 and is rotatably connected to the first base 10.

[0039] When the stacking mechanism 40 presses down a bottomless label paper 01, the rotary disk 30 rotates a certain angle, so that the stacked bottomless label paper 01 is misaligned. The rotation angle is α, and the degree of α ensures that the two adjacent bottomless label papers 01 after stacking do not completely overlap, which is convenient for removing the bottomless label paper 01. The angle of α is 2 - 10 degrees, preferably 5°.

[0040] The rotating disk 30 is rotated by the first driving mechanism 50. The first driving mechanism 50 uses a stepper motor, which is arranged below the first base 10. Its output shaft passes through the first base 10 and is connected to the rotating disk 30. A first through hole for the output shaft to pass through is provided on the first base 10, and a first bearing is arranged between the output shaft and the first through hole; the stepper motor can be locked to the first base 10 by the first screw.

[0041] A first anti-sticking layer is further provided on the upper end surface of the rotating disk 30 or an anti-sticking block 60 is provided. The anti-sticking block 60 is made of an anti-sticking rubber part to prevent the bottomless label paper 01 from sticking to the anti-sticking block 60, which is convenient for directly removing the stacked bottomless label paper 01 from the anti-sticking block 60; at the same time, in order to remove the stacked bottomless label paper 01, the anti-sticking block 60 is detachably arranged on the rotating disk 30. After stacking is completed, the anti-sticking block 60 with the bottomless paper label is directly removed and a new anti-sticking block 60 is replaced to achieve quick operation without affecting subsequent stacking. Of course, the stacked bottomless label paper 01 can also be directly removed from the rotating disk 30 or the anti-sticking block 60, and then subsequent stacking can be continued. The first anti-sticking layer can be directly attached to the rotating disk 30, or coated on the upper end surface of the rotating disk 30, or coated on the outer surface of the entire rotating disk 30. The anti-sticking block 60 can be installed on the rotating disk 30, for example, using glue or double-sided tape; or it can be detachably arranged on the rotating disk 30, for example, locked to the upper surface of the rotating disk 30 by a number of second screws, and a counterbore is provided on the upper end surface of the anti-sticking block 60 to facilitate embedding the heads of the second screws. For details, please refer to Figures 7 to 8 In the present utility model, the detachable structure of the anti-sticking block 60 is as follows: a groove 31 is provided on the upper end surface of the rotating disk 30, a first step matching the groove 31 is provided on the end surface of the anti-sticking block 60 that fits with the rotating disk 30, and a second step in the shape of a ring is further provided at the outer edge of the anti-sticking block 60. The inner side wall of the second step fits with the outer side wall of the rotating disk 30. With the above structure, if the anti-sticking block 60 is made of a rubber part, it can be well fitted with the rotating disk 30. For example, the first step and the groove 31 can adopt an interference fit.

[0042] The stacking device further includes a support base 70 disposed above the rotating disk 30 and used for supporting the bottomless label paper 01. A second anti-sticking layer is provided on the upper end surface or the outer surface of the support base 70. The support base 70 is disposed corresponding to the paper outlet 21 of the printing device 20. The support base 70 can be an entire support plate, and an avoidance position for the bottomless label paper 01 to pass through is provided on the support plate. Or two support bases 70 can be provided. Specifically, two strip-shaped structures can be used. The two support bases 70 are arranged side by side below the paper outlet 21 of the printing device 20, and the distance between the two support bases 70 can be used to support the bottomless label paper 01 without dropping, and can also ensure that the stacking mechanism 40 presses the bottomless label paper 01 above the rotating disk 30 or the anti-sticking block 60. Specifically, the distance between the two support bases 70 is less than the width of the label paper and greater than the width of the lower pressing plate 43. Since the bottomless label paper 01 is flexible, the lower pressing plate 43 can directly press down through the space between the two support bases 70. The printing device 20 adopted in the present invention has full cutting or half cutting, which can be selected according to actual needs. At the same time, in order to make the transmission smoother, a conveying device can be provided on both support bases 70. The conveying device includes a conveyor belt and a driving motor. The driving motor drives the conveyor belt to drive the bottomless label paper 01 to move. If the half-cutting method is adopted, since the stacking mechanism 40 will pull the next bottomless label paper 01 during the process of pressing down the bottomless label paper 01, a connecting plate 71 is provided between the two support bases 70 to play a certain supporting role.

[0043] For details, please refer to Figures 3 to 6, the stacking mechanism 40 includes a second base, a second driving mechanism 42 disposed on the second base, and a lower pressing plate 43 disposed below the second base and connected to the output end of the second driving mechanism 42. The second driving mechanism 42 drives the lower pressing plate 43 to move vertically above the rotating disk 30. The second driving structure adopts a screw linear motor, and the central axis of its screw 421 is arranged vertically. By driving the screw 421 to move vertically through the second driving mechanism 42, the lower pressing plate 43 is driven to move up and down. In order to ensure the stability and accuracy of the downward pressing of the lower pressing plate 43, the stacking mechanism 40 further includes a guide rod 44 for guiding the lower pressing plate 43 to move vertically. The guide rod 44 is movably connected to the second base and its bottom is disposed on the lower pressing plate 43. A guide sleeve is also disposed on the second base, and the guide sleeve corresponds to the guide rod 44. The guide rod 44 moves up and down within the guide sleeve. The second base is disposed on the printing device 20 or directly fixed on the first bottom plate. The screw linear motor is directly locked on the second bottom plate 41 through a plurality of third screws, and a second through hole for the screw 421 to pass through is disposed on the second bottom plate 41. The lower end of the screw 421 is rotatably connected to the lower pressing plate 43. The screw motor drives the screw 421 to rotate. When the screw 421 rotates, it can move up or down. Under the action of the four guide rods 44, the lower pressing plate 43 is driven to move up and down vertically. A connecting sleeve 45 is disposed on the lower pressing plate 43 for rotatably connecting to the end of the screw 421. A second bearing 46 is disposed between the screw 421 and the connecting sleeve 45 to facilitate the smooth rotation of the screw 421 and the connecting sleeve 45. The connecting sleeve 45 can be locked on the lower pressing plate 43 through a plurality of fourth screws; a stepped hole is disposed inside the connecting sleeve 45. The larger diameter part of the stepped hole is used for installing the second bearing 46, and the smaller diameter part is used for the screw 421 to pass through. After the screw 421 passes through, it passes through the second bearing 46, and then a limit block is disposed on the lower end surface of the screw 421. The limit block is fixedly disposed on the lower end surface of the screw 421 and can be embedded into the upper end surface of the lower pressing plate 43. The lower end surface of the second bearing 46 abuts against the end surface of the lower pressing plate 43. A plurality of internal threaded holes are disposed on the lower pressing plate 43 for screwing with the fourth screws. The fourth screws first pass through the connecting sleeve 45 and then are locked on the lower pressing plate 43.

[0044] For details, please refer to Figure 6The lower end surface of the lower pressing plate 43 is also provided with an adsorption layer 431, and the lower surface of the adsorption layer 431 is sticky, and the viscosity of the adsorption layer 431 is less than that of the bottomless label paper 01. When the lower pressing plate 43 is pressed down, the bottomless label paper 01 will be adsorbed on the lower surface of the lower pressing plate 43 by the adsorption layer 431 to prevent it from falling. The adsorbed bottomless label paper 01 can be stacked on the rotating disk 30 more accurately. At the same time, since the viscosity is less than the adhesive on the back of the bottomless label paper 01, the bottomless label paper 01 will not be taken away during the upward movement of the lower pressing plate 43. Of course, the lower pressing plate 43 can also directly adopt an adsorption disk. Specifically, the lower pressing plate 43 is replaced by an adsorption disk, or the adsorption disk is directly installed on the lower end surface of the lower pressing plate 43, and the bottomless label paper 01 is adsorbed under the adsorption disk by connecting a vacuum device, and then pressed down to the rotating disk 30 or the anti-sticking block 60.

[0045] The working principle of the bottomless paper stacking device of the utility model is as follows:

[0046] First, use the printing device 20 (a conventional printer that can print bottomless label paper 01 with adhesive backing, and also with half-cut and full-cut) to print the bottomless label paper 01, and move it to the support seat 70. The bottomless label paper 01 to be pressed down by the stacking mechanism 40 is basically moved to the bottom of the lower pressure plate 43, and it is best not to contact the connecting plate 71. After moving into place, the lower pressure plate 43 is driven down to the rotating disk 30 or the anti-sticking block 60 by the second driving mechanism 42. The second driving mechanism 42 is reset for subsequent stacking, and the first driving mechanism 50 drives the rotating disk 30 to rotate a certain angle and then stop, waiting for the next stacking.

[0047] To sum up, the bottomless paper stacking device of the present invention is used in conjunction with the stacking mechanism by setting a rotating disk. When the stacking mechanism is pressed down once, the rotating disk can rotate a certain angle, so that the stacked bottomless label paper is misaligned, which is convenient for subsequent tearing off. At the same time, the stacking process ensures that the bottomless label paper is laid flat to avoid wrinkles.

[0048] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
