Description

Technical Field

[0001] This invention relates to the field of label printing technology, specifically an integrated label printing device. Background Technology

[0002] The widespread use of labels and the continuous development of label varieties have naturally driven the development of label printing technology. Label printing encompasses all printing methods, including letterpress, relief, gravure, and screen printing, with varying applications in different countries. Currently, domestic label printing mainly uses letterpress printing, offset printing, flexographic printing, and screen printing.

[0003] Offset printing is a widely used printing method. It is fast, has high printing clarity, accurate registration, and rich printing layers. However, it is less durable and the ink layer is relatively light, making it unsuitable for printing brightly colored labels.

[0004] Letterpress printing produces images with good clarity and faster printing speed. Its color strength and durability are better than offset printing, but slightly worse than screen printing. However, its tonal reproduction and registration accuracy are better than both screen printing and flexographic printing.

[0005] The biggest advantage of screen printing is its thick ink layer and good coverage, but it is slow, has poor tonal representation, and low registration accuracy. Therefore, screen printing machines can be used to print labels with weak tonal representation.

[0006] Flexographic printing produces prints with moderate characteristics, but this technology requires high levels of skill in processing anilox rollers and skilled workers. Although the machines are relatively simple, the process is quite complex.

[0007] The current method of printing labels using rollers generally employs single-sided printing, where the colored patterns on the rollers are printed onto the label paper to complete the label printing process. However, in practical applications, it is often necessary to print on transparent label paper and then affix it to a transparent substrate. While information can be obtained from the back, the current single-sided printing equipment often results in incomplete, inaccurate, and difficult-to-read information when accessing the label from the back, necessitating switching to the front of the label. Summary of the Invention

[0008] To overcome the shortcomings of existing roller-printed labels, which rely on single-sided printing using existing label printing equipment and suffer from incomplete, inaccurate, and difficult-to-identify information when obtaining information from the back of the label, requiring a switch to the front of the label, this application provides an integrated label printing device. By simultaneously operating first hydraulic cylinders of different heights or operating a single first hydraulic cylinder, the device controls the corresponding slide to push the adjusting roller to apply pressure to the surface of the label paper. A second hydraulic cylinder controls the adjusting bracket to rotate between the face frame and the back frame, adjusting the distance between the two printing cylinders and the front and back of the label paper. This allows control over the adhesion between one side of the label paper and the surface of one printing cylinder, or between both sides and the surfaces of the two printing cylinders, facilitating switching between single-sided and double-sided label printing based on actual usage.

[0009] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0010] An integrated label printing device includes a printing cylinder and an adjusting roller, wherein there are two printing cylinders;

[0011] There are two adjusting rollers;

[0012] The two adjusting rollers are arranged vertically, and each end of the two adjusting rollers is provided with a vertical frame. A first hydraulic cylinder is provided between one end of the adjusting roller and a vertical frame.

[0013] The two printing cylinders are arranged symmetrically on the left and right. Each end of the two printing cylinders is provided with an adjustment bracket. A back frame and a face frame are sleeved on the outside of the adjustment bracket. A second hydraulic cylinder is provided between each end of the adjustment bracket and the inner wall of the face frame.

[0014] In one possible implementation, both ends of the two printing cylinders are interference-fitted with second bearings, which are interference-fitted to the interior of the adjusting bracket, with one end supporting the printing cylinder protruding from the interior of the adjusting bracket.

[0015] In one possible implementation, the outer wall of the back frame is machined with two corner frames arranged vertically, and the two upright frames are respectively assembled and connected to the two corner frames by bolts. The front frame is assembled and connected to one side of the back frame.

[0016] In one possible implementation, the surfaces at both ends of the adjustment bracket are machined into arc shapes, and multiple roller sleeves are rolled inside both ends of the adjustment bracket, with the surfaces of the multiple roller sleeves fitting against the inner walls of the face frame and the back frame.

[0017] In one possible implementation, the inner wall of the face frame is formed with two supports, and prism blocks are machined on the surfaces of both ends of one side of the adjusting bracket. Support bushings are assembled to the outside of the prism blocks. One end of the second hydraulic cylinder is sleeved on the outside of the support bushing, and the other end of the second hydraulic cylinder is hinged to the inside of the support.

[0018] In one possible implementation, the two second hydraulic cylinders are parallel to each other and symmetrical about the center of the face frame. The two second hydraulic cylinders work synchronously to control the adjustment bracket to rotate between the face frame and the back frame.

[0019] In one possible implementation, a slide is provided at one end of the first hydraulic cylinder, a support shaft is machined on one side of the slide, a first bearing is interference-fitted inside the other side of the slide, one end of the adjusting roller is interference-fitted into the inside of the first bearing, the other end of the first hydraulic cylinder is hinged and fixed to the upright, and one end of the first hydraulic cylinder is sleeved on the outside of the support shaft.

[0020] In one possible implementation, the frame has a slide rail machined inside, the slide block has an I-shaped cross-section, and the slide block is slidably connected inside the slide rail.

[0021] In one possible implementation, the first hydraulic cylinders located at the top and bottom of the back frame are respectively hinged to the two ends of two vertically arranged uprights, and the first hydraulic cylinders located at the top and bottom of the back frame control two adjusting rollers to move towards each other between the two uprights at the same height.

[0022] The beneficial effects of this application are as follows:

[0023] Firstly, in this solution, by using two first hydraulic cylinders at the same height to control the slide to push the adjusting roller to apply pressure to one side of the label paper, the surface of one side of the label paper can be moved away from one printing cylinder, while the surface of the other side is attached to the surface of another printing cylinder, which facilitates single-sided label printing.

[0024] Secondly, in this solution, by having the first hydraulic cylinders at different heights work simultaneously, the corresponding slide blocks are controlled to push the adjusting rollers to apply pressure to the surface of the label paper. At the same time, the second hydraulic cylinder between the adjusting bracket and the face frame is used to control the adjusting bracket to rotate between the face frame and the back frame, adjusting the distance between the two printing cylinders and the front and back of the label paper. This allows the surfaces on both sides of the label paper to fit more tightly with the surface of the printing cylinders, ensuring clarity and convenience when printing labels on both sides of the label paper.

Label paper. Detailed Implementation

[0032] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0033] Example 1:

[0034] This embodiment describes the specific structure of an integrated label printing device, which can be referred to in detail below. Figures 1-6 As shown, it includes two printing cylinders 2 and two adjusting rollers 1. Both ends of the two printing cylinders 2 are provided with an adjusting bracket 8. The adjusting bracket 8 is sleeved with a back frame 3 and a face frame 11. A second hydraulic cylinder 9 is provided between both ends of the adjusting bracket 8 and the inner wall of the face frame 11.

[0035] The two printing cylinders 2 are arranged symmetrically on the left and right. By making the two second hydraulic cylinders 9 parallel to each other and symmetrical about the center of the face frame 11, when the two second hydraulic cylinders 9 work synchronously, the adjusting bracket 8 can be controlled to rotate between the face frame 11 and the back frame 3. The adjusting bracket 8 can be used to control the two printing cylinders 2 to switch from a horizontal state to an inclined state, so that the label paper 19 waiting to be printed can simultaneously adhere to the pattern on the surface of the two printing cylinders 2 as it passes between the two printing cylinders 2.

[0036] Secondly, in order to reduce the resistance of the printing cylinder 2 rotating between the two adjusting supports 8, such as Figure 3As shown, both ends of the two printing cylinders 2 are interference-fitted with second bearings 13. By connecting the second bearings 13 to the inside of the adjusting bracket 8 through the interference fit, one end of the printing cylinder 2 passes through the inside of the adjusting bracket 8. When the label paper 19 is pulled between the two printing cylinders 2 to perform label printing, the friction between the connection point of the printing cylinder 2 and the adjusting bracket 8 can be reduced.

[0037] Furthermore, to facilitate the connection of the second hydraulic cylinder 9 between the face frame 11 and the adjusting bracket 8, so that the second hydraulic cylinder 9 can control the movement of the adjusting bracket 8 within the face frame 11 and the back frame 3, such as... Figure 2 and Figure 3 As shown, the inner wall of the face frame 11 is formed with two supports 10. The surfaces of both ends of one side of the adjusting bracket 8 are machined with prism blocks 14. The outer side of the prism blocks 14 is connected with a support bushing 15. By assembling the face frame 11 to one side of the back frame 3, one end of the second hydraulic cylinder 9 is sleeved on the outside of the support bushing 15, and the other end of the second hydraulic cylinder 9 is hinged to the inside of the support 10. This allows the second hydraulic cylinder 9 to be stably connected between the inner wall of the face frame 11 and one end of the adjusting bracket 8.

[0038] Furthermore, in order to reduce the resistance of the adjusting bracket 8 rotating between the face frame 11 and the back frame 3, such as... Figure 3 As shown, the surfaces at both ends of the adjusting bracket 8 are processed into arc shapes, and multiple roller sleeves 16 are rolled inside both ends of the adjusting bracket 8. By making the surfaces of the multiple roller sleeves 16 fit against the inner walls of the face frame 11 and the back frame 3, the resistance of the adjusting bracket 8 when it moves under the support of the face frame 11 and the back frame 3 is reduced by the roller sleeves 16 rolling on the inner walls of the face frame 11 and the back frame 3.

[0039] By adopting the above technical solution:

[0040] The above design involves mounting the two ends of the two printing cylinders 2 inside the two adjusting brackets 8, so that the two second hydraulic cylinders 9, which are hinged to the inner wall of the face frame 11, are connected to the two ends of the adjusting brackets 8 through the support bushing 15 and the prism block 14. The adjusting brackets 8 are supported by the back frame 3 and the face frame 11. When it is necessary to control the two printing cylinders 2 to simultaneously perform label printing on the surface of the label paper 19, the two second hydraulic cylinders 9 work synchronously to control the adjusting brackets 8 to rotate between the face frame 11 and the back frame 3 (the adjusting brackets 8 at both ends of the printing cylinders 2 are the same), so as to adjust the tilt angle of the two printing cylinders 2 and adjust the distance between the two printing cylinders 2 and the front and back of the label paper 19, so that the back and front of the label paper 19 are respectively aligned with the texture of the surface of the two printing cylinders 2.

[0041] Example 2:

[0042] Based on Example 1, this example describes the specific structure of the adjusting roller 1. Two adjusting rollers 1 are arranged vertically, and each end of the two adjusting rollers 1 is provided with a support frame 6. A first hydraulic cylinder 7 is provided between one end of the adjusting roller 1 and a support frame 6. A slide block 12 is provided at one end of the first hydraulic cylinder 7. A support shaft 18 is machined on one side of the slide block 12, and a first bearing 17 is interference-fitted inside the other side of the slide block 12. One end of the adjusting roller 1 is interference-fitted into the interior of the first bearing 17.

[0043] Among them, the outer wall of the back frame 3 is processed with two corner frames 4 set at the top and bottom. By using bolts to assemble and connect the two upright frames 6 to the two corner frames 4 respectively, the adjusting roller 1 can be set between the two upright frames 6, so that the two upright frames 6 can cooperate with the label paper 19 for label printing work at the top and bottom of the two printing cylinders 2.

[0044] Secondly, to facilitate the connection of the first hydraulic cylinder 7 between the slide block 12 and the upright frame 6, so that the first hydraulic cylinder 7 controls the slide block 12 to slide inside the upright frame 6, as follows: Figure 2 , Figure 4 and Figure 5 As shown, the internal structure of the upright 6 has a slide rail 5. By hinged to the two ends of the two uprights 6 located at the top and bottom of the back frame 3 respectively, the other end of the first hydraulic cylinder 7 is sleeved on the outside of the support shaft 18, so that the first hydraulic cylinder 7 can be assembled between the slide block 12 and the upright 6.

[0045] By setting the cross section of the slide block 12 to an I-shape, the first hydraulic cylinder 7 located at the top and bottom of the back frame 3 can control the two adjusting rollers 1 to move towards each other between the two uprights 6 at the same height.

[0046] By adopting the above technical solution:

[0047] The above design uses adjusting rollers 1, which are supported by two uprights 6 and two slides 12, at the top and bottom of the two printing cylinders 2. A first hydraulic cylinder 7 is connected between the surface of the slide 12 and one end of the upright 6. When the label paper 19 passes between the two printing cylinders 2 for double-sided label printing, the two first hydraulic cylinders 7 at the same height can be used to control the slides 12 at the corresponding positions to push the adjusting rollers 1 to apply pressure to one side of the label paper 19, so that one side of the label paper 19 moves away from one printing cylinder 2 and the other side of the label paper adheres to the other printing cylinder 2, which facilitates single-sided label printing.

[0048] At the same time, when the first hydraulic cylinders 7 at the top and bottom of the two printing cylinders 2 are activated, the corresponding slides 12 are controlled to push the adjusting rollers 1 to apply pressure to the surface of the label paper 19. When the two printing cylinders 2 are tilted by the adjusting brackets 8, the surfaces on both sides of the label paper 19 can be more closely attached to the surface of the printing cylinders 2, which helps to ensure the clarity of the labels printed on the surface of the label paper 19 by the printing cylinders 2.

[0049] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
