Description

Technical Field

[0001] This application relates to the field of label paper production technology, and more specifically, to a label paper production conveying device. Background Technology

[0002] Driven by the rapid development of the packaging, electronics, daily chemical, and food industries, label paper, as the core carrier for product identification and information transmission, has seen continuous growth in market demand and expansion in production scale. The production process of label paper involves multiple steps, including substrate cutting, printing, gluing, die-cutting, and lamination. As a key piece of equipment connecting these steps, the conveying device must ensure continuous, precise, and low-damage transfer of label paper between different processing stages.

[0003] In related technologies, for example, the prior art patent CN205633312U provides a device that uses a vacuum pump to create a vacuum in the enclosed space formed by the sealing cover and the conveyor belt. This creates an upward suction force in the vent holes, causing the label paper at the top of the support plate to be adsorbed onto the bottom of the conveyor belt. The motor drives the active shaft to rotate, and the driven shaft causes the transmission belt to move the label paper. When the label paper detaches from the bottom of the sealing cover, it falls onto the conveyor, thus continuously and orderly placing the label paper on the top of the conveyor. The conveyor then transports the label paper to the next process. Because this conveying device uses a vacuum to adsorb the label paper onto the bottom of the conveyor belt, and only one label paper can be adsorbed at a time, it ensures that the label paper is transported in an orderly manner.

[0004] While the existing technical solutions described above have solved the problems mentioned in the background, the conveying process after the gluing process is a key link in ensuring product quality and production efficiency during the production of self-adhesive labels, medical adhesive labels, and other adhesive label papers. After the adhesive is applied, the adhesive layer of such adhesive label papers is in a semi-cured or incompletely cured state, and the surface has strong adhesion. The adhesive is easy to stick to the conveyor belt of the conveyor, affecting the next conveying.

[0005] In view of this, we propose a label paper production conveying device. Utility Model Content

The device achieves the removal of the adhesive by scraping, ultrasonic cleaning, and drying at the return end of the conveyor, thus cleaning the adhesive on the surface of the conveyor belt and preventing it from being used in the next round of conveying.

[0026] By setting up a conveyor 1, a scraping mechanism, an ultrasonic cleaning mechanism, a drying mechanism, a support column 2, and a grounding plate 3, in use, the conveyor 1 first conveys the label paper, then the support column 2 and the grounding plate 3 provide support for the conveyor 1, and then the return end of the conveyor belt on the conveyor 1 passes through the scraping mechanism, the ultrasonic cleaning mechanism, and the drying mechanism to clean the adhesive on the surface of the conveyor belt, and then the drying mechanism dries the surface of the conveyor belt to prevent the adhesive on the surface of the conveyor belt from affecting the next conveying.

[0027] Reference Figure 3 The scraping mechanism includes a fixed plate 4; the fixed plate 4 is fixedly mounted on the side wall of the conveyor 1; there are two fixed plates 4 arranged symmetrically, and a scraper 5 is provided between the two fixed plates 4; the scraper 5 is made of rubber; connecting rods 6 are provided at both ends of the scraper 5; a sliding groove 7 is provided on the fixed plate 4; the connecting rod 6 passes through the sliding groove 7 and is located at one end of the sliding groove 7; a locking bolt 8 is provided on the connecting rod 6.

[0028] By setting up a fixed plate 4, a scraper 5, a connecting rod 6, a sliding groove 7, and a locking bolt 8, in use, the fixed plate 4 is first fixed on the conveyor 1, then the two connecting rods 6 are connected to both ends of the scraper 5 and pass through the sliding groove 7. The height of the scraper 5 is adjusted by the sliding of the connecting rods 6 in the sliding groove 7 so that the scraper 5 is always in contact with the return end surface of the conveyor belt. After the position of the scraper 5 is adjusted, the connecting rod 6 is locked by the locking bolt 8.

[0029] Reference Figure 2 The ultrasonic cleaning mechanism includes a pressure roller 9; the pressure roller 9 is located at the return end of the conveyor 1; the middle of the return end of the conveyor belt on the conveyor 1 is V-shaped due to the action of the pressure roller 9; an ultrasonic cleaner 10 is provided on the middle of the return end of the conveyor belt on the conveyor 1; the ultrasonic cleaner 10 is provided with a water inlet 11 and a water outlet 12.

[0030] By setting up a pressure roller 9, an ultrasonic cleaner 10, a water inlet 11, and a water outlet 12, during use, the pressure roller 9 can pull the middle of the return end of the conveyor belt into a V shape, so that the conveyor belt can pass through the ultrasonic cleaner 10, allowing the ultrasonic cleaner 10 to perform ultrasonic cleaning on the stubborn adhesive on the surface of the conveyor belt. Then, the water inlet 11 can inject water into the ultrasonic cleaner 10, and the water outlet 12 can discharge the wastewater.

[0031] Reference Figure 5 The drying mechanism includes a drying chamber 13; the drying chamber 13 is located on one side of the ultrasonic cleaning mechanism; the return end of the conveyor belt of the conveyor 1 passes through the drying chamber 13; a drying fan 14 is installed on the drying chamber 13; and a pressure relief valve 15 is installed on the drying chamber 13.

[0032] By setting up a drying chamber 13, a drying fan 14, and a pressure relief valve 15, during use, the conveyor belt passes through the drying chamber 13, and hot air is injected into the drying chamber 13 by the drying fan 14 to dry the surface of the conveyor belt. Then, the pressure relief valve 15 can relieve the pressure inside the drying chamber 13 to prevent excessive air pressure inside the drying chamber 13.

[0033] Reference Figure 1 and Figure 2 The conveyor 1 is provided with a negative pressure hole 16; a negative pressure fan 17 is provided below the negative pressure hole 16; the number of negative pressure holes 16 is several groups and they are evenly distributed.

[0034] By setting up negative pressure holes 16 and negative pressure fans 17, when the label paper enters the conveyor 1, the label paper is attracted to the conveyor 1 by the combined action of negative pressure fans 17 and negative pressure holes 16, thus preventing the label paper from shifting during the conveying process.

[0035] Reference Figure 3 An extension plate 18 is fixedly installed on the fixed plate 4; there are four extension plates 18 arranged symmetrically; a sludge receiving plate 19 is fixedly installed at the lower end of the extension plate 18.

[0036] By setting up the extension plate 18 and the sludge receiving plate 19, the extension plate 18 is fixed on the fixed plate 4 during use, which can fix the sludge receiving plate 19. The adhesive scraped off by the scraper 5 falls onto the sludge receiving plate 19 for unified collection and treatment.

[0037] Reference Figure 1 The conveyor 1 is equipped with a controller 20; both the conveyor 1 and the negative pressure fan 17 are electrically connected to the controller 20.

[0038] With the controller 20 in use, the controller 20 can control the negative pressure fan 17. After the conveyor 1 transports the label paper to the other end, the controller 20 shuts down the corresponding negative pressure fan 17, which loses its adsorption force on the label paper, allowing the label paper to detach from the conveyor.

[0039] In summary, the label paper production conveying device disclosed in this application, when in use, firstly, the conveyor 1 can convey the label paper, then the support column 2 and the ground plate 3 can provide support for the conveyor 1, then the return end of the conveyor belt on the conveyor 1 can pass through the scraping mechanism, the ultrasonic cleaning mechanism and the drying mechanism in one go to clean the adhesive on the surface of the conveyor belt, and then the drying mechanism dries the surface of the conveyor belt to prevent the adhesive on the surface of the conveyor belt from affecting the next conveying. The fixing plate 4 is fixed on the conveyor 1, then the two connecting rods 6 are connected to the two ends of the scraper 5 and pass through the sliding groove 7. The height of the scraper 5 is adjusted by the sliding of the connecting rods 6 in the sliding groove 7 so that the scraper 5 is always in contact with the surface of the return end of the conveyor belt. After the position of the scraper 5 is adjusted, the connecting rods 6 are locked by the locking bolts 8, and the pressure roller 9 can pull the middle of the return end of the conveyor belt into a V shape so that the conveyor belt can pass through the ultrasonic cleaner 10, so that the ultrasonic cleaner 10 cleans the surface of the conveyor belt. Stubborn adhesive on the surface is ultrasonically cleaned. Then, the water inlet 11 can inject water into the ultrasonic cleaner 10, and the water outlet 12 can discharge the wastewater. The conveyor belt passes through the drying box 13, and hot air is injected into the drying box 13 by the drying fan 14 to dry the surface of the conveyor belt. Then, the pressure relief valve 15 can relieve the pressure inside the drying box 13 to prevent the air pressure inside the drying box 13 from being too high. When the label paper enters the conveyor 1, the negative pressure fan 17 and the negative pressure hole 16 work together to adsorb the label paper onto the conveyor 1, preventing the label paper from shifting during the conveying. The extension plate 18 is fixed on the fixing plate 4 and can fix the dirt receiving plate 19. The adhesive scraped off by the scraper 5 falls onto the dirt receiving plate 19 for unified collection and treatment. Finally, the controller 20 can control the negative pressure fan 17. After the conveyor 1 transports the label paper to the other end, the controller 20 turns off the corresponding negative pressure fan 17, loses the adsorption force on the label paper, and allows the label paper to be removed from the conveyor.
