Description

Technical Field

[0001] Embodiments of this disclosure relate to the field of label cleaning technology, and more specifically, to a label printing apparatus with a cleaning function. Background Technology

[0002] In today's consumer market, labels are ubiquitous, carrying key information such as brand identity, product details, and usage instructions, serving as a crucial window for consumers to understand products. From exquisitely designed cosmetic labels to information-rich electronic product labels, the printing quality of labels directly impacts a product's market image and consumers' purchasing decisions.

[0003] In existing technologies, label printing machines are generally used for label printing. A label printing machine is a specialized device for printing various labels and is widely used in many industries such as food, pharmaceuticals, and daily chemicals. During operation, the label material is first unwound from the unwinding mechanism. As it passes through the printing unit, the graphic information on the printing plate is transferred to the surface of the label material using ink. After printing, the labels are dried in a drying unit and then enter the die-cutting unit to be die-cut according to the designed shape. Finally, the rewinding mechanism rewinds the finished labels.

[0004] During the label printing process, the labels themselves are highly susceptible to various contaminants. During storage and transportation, label raw materials may have dust, lint, and other impurities from the air adhering to their surfaces. These contaminants can seriously interfere with the printing effect, preventing the ink from adhering evenly and causing defects such as spots and broken lines in the printed pattern, which greatly reduces the aesthetics and readability of the labels.

[0034] The beneficial effects of the embodiments disclosed herein are as follows:

[0035] 1. In this disclosure, the reciprocating moving mechanism and the fan are designed to facilitate the rotation of the reciprocating screw by the operation of the third motor.

[0054] like Figures 1-6As shown, this invention illustrates a label printing apparatus with a cleaning function according to an embodiment of the present disclosure. The apparatus includes a printing machine body 1 with an inlet, a feeding seat 2, a cleaning trough 4, a cleaning frame 5, a cleaning roller 6, a reciprocating movement mechanism, a rotating mechanism, and a feeding mechanism. The feeding seat 2 has a feeding port 3 connected to the inlet. The cleaning trough 4 is located on the inner top wall of the feeding port 3. A U-shaped cleaning frame 5 is slidably disposed within the cleaning trough 4. The cleaning roller 6 is rotatably disposed within the cleaning frame 5, and cleaning bristles are evenly distributed on the sidewalls of the cleaning roller 6. The reciprocating movement mechanism is disposed on the cleaning frame 5 to drive the cleaning frame 5 to reciprocate within the cleaning trough 4. The rotating mechanism is disposed on the cleaning frame 5 to drive the cleaning roller 6 to rotate. The feeding mechanism is disposed on the feeding seat 2 to drive the label paper to move within the feeding port 3.

[0055] Reference Figures 2-4 The feeding mechanism includes a first cavity, a first feeding roller 7, a feeding frame 8, a first motor 10, and an electric push rod 11. Two first cavities are formed within the feeding base 2, and each first cavity communicates with the feeding port 3. The first feeding roller 7 is rotatably mounted in one of the first cavities located on one side of the feeding port 3. The feeding frame 8 is slidably mounted within the first cavity, and a second feeding roller 9 is rotatably mounted within the feeding frame 8. The first motor 10 is fixedly mounted on the feeding base 2, and its output end is fixedly connected to the first feeding roller 7. The electric push rod 11 is fixedly mounted within the feeding... Rubber pads are fixedly installed on the side walls of the first feed roller 7 and the second feed roller 9 between the frame 8 and the side wall of the first cavity. After the label paper is inserted into the feed port 3, the operation of the electric push rod 11 drives the feed frame 8 and the second feed roller 9 to move, so that the label paper can be pressed by the first feed roller 7 and the second feed roller 9. At the same time, the operation of the first motor 10 can drive the first feed roller 7 to rotate, so that the label paper can be driven to move in the feed port 3 and be fed into the printing machine body 1.

[0056] Reference Figure 3It also includes a limiting mechanism, which is set in the first cavity to limit the position of the label paper. The limiting mechanism includes a limiting plate 12, a limiting opening, and a relative moving mechanism. Two limiting plates 12 are slidably arranged in the first cavity, and the limiting opening is opened on the limiting plate 12. The first feed roller 7 and the second feed roller 9 pass through the limiting opening. The relative moving mechanism is set in the first cavity to drive the two limiting plates 12 in the same first cavity to move relative to each other. The relative moving mechanism includes a bidirectional screw 13 and a second motor 14. The rotating part is located in the first cavity. The bidirectional screw 13 passes through the two limiting plates 12 through the threaded engagement. The second motor 14 is fixedly mounted on the feed seat 2. The output end of the second motor 14 is fixedly connected to the bidirectional screw 13. The operation of the second motor 14 can drive the bidirectional screw 13 to rotate. At the same time, the threaded engagement between the bidirectional screw 13 and the limiting plates 12 can drive the two limiting plates 12 to move relative to each other. Thus, the limiting plates 12 can limit the label paper, thereby preventing the label paper from shifting position during feeding and cleaning.

[0057] Reference Figures 4-6 The reciprocating moving mechanism includes a moving port, a reciprocating screw 15, and a third motor 16. The moving port is located on the cleaning frame 5, and a screw nut is fixedly installed inside the moving port. The reciprocating screw 15 is rotatably installed in the cleaning tank 4, and the reciprocating screw 15 passes through the screw nut through a threaded engagement. The third motor 16 is fixedly installed on the feeding seat 2, and the output end of the third motor 16 is fixedly connected to the reciprocating screw 15. A fan 22 is installed on the feeding seat 2, and the input end of the fan 22 extends into the cleaning tank 4. The output end of the fan 22 is connected to the external environment. Specifically, the operation of the third motor 16 drives the reciprocating screw 15 to rotate. At the same time, the threaded engagement between the reciprocating screw 15 and the screw nut drives the cleaning frame 5 and the cleaning roller 6 to reciprocate within the cleaning tank 4. This facilitates the cleaning of impurities attached to the label paper by the cleaning bristles on the cleaning roller 6, and also facilitates the discharge of these impurities from the cleaning tank 4 by the operation of the fan 22.

[0058] Reference Figure 5 and Figure 6The rotating mechanism includes a second cavity, a second bevel gear 18, and a drive mechanism. The second cavity is located on the cleaning frame 5. A first bevel gear 17 is rotatably mounted on the side wall of the second cavity near the cleaning roller 6. A drive rod is fixed between the first bevel gear 17 and the cleaning roller 6. The second bevel gear 18 is rotatably mounted on the side wall of the second cavity and meshes with the first bevel gear 17. The drive mechanism is mounted on the cleaning frame 5 and is used to drive the second bevel gear 18 to rotate. The drive mechanism includes a drive prism 19 and a fourth motor 20. The drive prism 19 is rotatably mounted in the cleaning trough 4 and passes through the cleaning frame 5 and the second bevel gear 18. The drive prism 19 is slidably connected to the cleaning frame 5. The fourth motor... The fourth motor 20 is fixedly installed on the feed seat 2. The output end of the fourth motor 20 is fixedly connected to the drive prism 19. The second bevel gear 18 has a first drive port 21, and the cleaning frame 5 has a second drive port. The drive prism 19 passes through the first drive port 21 and the second drive port. The drive prism 19 is slidably connected to the side wall of the first drive port 21. The operation of the fourth motor 20 drives the drive prism 19 to rotate. At the same time, the sliding engagement between the drive prism 19 and the second bevel gear 18 drives the second bevel gear 18 to rotate. Then, the meshing between the second bevel gear 18 and the first bevel gear 17 drives the first bevel gear 17, the drive rod, and the cleaning roller 6 to rotate, thereby improving the cleaning effect of the cleaning brush bristles on the label paper.

[0059] In this embodiment, during use, after the operator inserts the label paper into the feed inlet 3, the electric push rod 11 drives the feed frame 8 and the second feed roller 9 to move, thereby pressing the label paper with the first feed roller 7 and the second feed roller 9. Simultaneously, the first motor 10 drives the first feed roller 7 to rotate, thus driving the label paper to move within the feed inlet 3 and feed it into the printing machine body 1. During the feeding process, the operator controls the second motor 14, which drives the bidirectional screw 13 to rotate. The threaded engagement between the bidirectional screw 13 and the limiting plate 12 causes the two limiting plates 12 to move relative to each other, thereby limiting the label paper and preventing positional displacement during feeding and cleaning. During the process, the operator controls the third motor 16 and the fourth motor 20 to work. The operation of the third motor 16 drives the reciprocating screw 15 to rotate. At the same time, the threaded engagement between the reciprocating screw 15 and the screw nut drives the cleaning frame 5 and the cleaning roller 6 to move back and forth in the cleaning tank 4. This facilitates the cleaning of impurities attached to the label paper by the cleaning bristles on the cleaning roller 6. At the same time, the operation of the fan 22 facilitates the discharge of these impurities from the cleaning tank 4. Meanwhile, the operation of the fourth motor 20 drives the drive prism 19 to rotate. The sliding engagement between the drive prism 19 and the second bevel gear 18 drives the second bevel gear 18 to rotate. In turn, the meshing of the second bevel gear 18 with the first bevel gear 17 drives the first bevel gear 17, the drive rod, and the cleaning roller 6 to rotate, thereby improving the cleaning effect of the cleaning bristles on the label paper.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
