Description

Technical Field

[0001] The utility model relates to the technical field of label drying, in particular to a drying device for label production. Background Technique

[0002] A label is an identification information paper card or sign additionally attached to an object. To obtain a perfect-quality label, in addition to configuring a high-quality barcode printer, a reasonable selection of label paper is also a very important link. At present, self-adhesive labels are more commonly used in the barcode printer industry. A self-adhesive label consists of a release paper, a face paper, and an adhesive that bonds the two. The release paper is commonly known as the "base paper" and has an oily surface. The base paper has an isolating effect on the adhesive, so it is used as the attachment body for the face paper to ensure that the face paper can be easily peeled off from the base paper.

[0003] A drying device for label production disclosed in the existing patent (publication number: CN218986097U) enables a label to pass through between annular heating tubes by arranging the annular heating tubes, and enables the label not to contact other objects during the process of passing through the annular heating tubes and being dried, so that the label can be evenly heated during drying, and finally the drying efficiency of the label can be improved; by arranging a barrier structure, the ventilation volume of the through slot can be adjusted according to requirements, so that the amount of air heated by the annular heating tubes escaping from the through slot can be reduced, and thus the power consumption for drying the label can be reduced.

[0004] However, the above technical solution still has certain defects. The ink on the surface of the label may cause the label to wrinkle during the drying process, resulting in damage to the surface of the label. At the same time, the odor generated by the ink on the surface of the label during the drying process is somewhat toxic. If the gas spreads everywhere, it will cause harm to the human body if inhaled for a long time. Therefore, a drying device for label production is proposed. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0031] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0032] A drying device for label production, as Figures 1-7 shown, includes a base main body 100. A drying box 110 is fixedly installed on the upper surface of the base main body 100. Two through grooves 120 are symmetrically opened at the front and rear ends of the drying box 110. The through grooves 120 penetrate the outer wall and the inner wall of the drying box 110. A plurality of groups of annular heating lamp tubes 160 are installed in the drying box 110 at equal intervals. Each group of annular heating lamp tubes 160 is fixedly installed on the inner wall of the drying box 110 by bolts. The traction belt passes through the plurality of groups of annular heating lamp tubes 160. A barrier component 200 is provided above the through groove 120 at the front end of the drying box 110. A flattening component 300 is installed inside the drying box 110. A purification component 400 is provided inside the side wall of the drying box 110. A traction belt is horizontally arranged inside the drying box 110; the flattening component 300 includes supporting plates 310 fixedly installed on the front and rear side walls of the inner cavity of the drying box 110. The supporting plates 310 are arranged below the traction belt. The front and rear side walls of the inner cavity of the drying box 110 are connected by bearings above the traction belt with a rotating shaft 320. A flattening roller 330 is fixedly sleeved on the outer wall of the rotating shaft 320. The flattening roller 330 is in contact with the upper surface of the traction belt. Scrapers 340 are fixedly installed on the front and rear side walls of the inner cavity of the drying box 110 obliquely above the flattening roller 330. The scrapers 340 are inclined, and one side of the scrapers 340 is in contact with the flattening roller 330.

[0033] The flattening assembly 300 is arranged at the rear end of the drying box 110. The traction belt is used to drive the label to pass through several groups of annular heating tubes 160 for heating and drying, and then pass through the flattening roller 330. The friction force drives the flattening roller 330 to rotate. The flattening roller 330 cooperates with the support plate 310 to flatten the surface of the dried label, preventing the label from wrinkling during the drying process and causing damage to the label surface. At the same time, the scraper 340 is inclined to scrape the surface of the flattening roller 330, scraping off the label adhered to the surface of the flattening roller 330 to prevent the label from being damaged by the rotation of the flattening roller 330 when it adheres to the surface of the flattening roller 330.

[0034] Please refer specifically to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown in

[0035] By starting the exhaust fan 470, the gas generated during the drying of the label is drawn into the activity chamber 410 through the air inlet hole 440. Using the ventilation holes 430 staggered on both sides of the U-shaped partition 420, the gas passes through the groups of ventilation holes 430 until each U-shaped groove is filled, so that the gas with heat fills the entire activity chamber 410, achieving a certain heat preservation effect. Finally, it is discharged from the air outlet hole 450 and enters the purification box 460. After being purified and filtered by the activated carbon 480, it is discharged from the air outlet pipe 490 to prevent the toxic gas from spreading everywhere and causing harm to the staff's body.

[0036] Please refer specifically to Figure 1 and Figure 2As shown, on the upper surface of the base body 100, two sets of fixed seats 130 are fixedly installed at the rear side of the drying box 110. A winding roller 140 is connected between the two sets of fixed seats 130 through bearings. On one side of a set of fixed seats 130, a winding motor 150 is fixedly installed. The output shaft of the winding motor 150 is connected to the winding roller 140. The traction belt passes through the drying box 110 and is finally wound on the winding roller 140.

[0037] Start the winding motor 150 to drive the winding roller 140 to rotate. Thus, the traction belt will pull the label passing through the drying box 110 and the annular heating lamp tube 160 backward. When driving the label to pass through the annular heating lamp tube 160, the annular heating lamp tube 160 will uniformly heat and dry the label, thereby improving the drying efficiency of the label.

[0038] Please refer particularly to Figure 1 and 4 As shown, the barrier assembly 200 includes a fixing plate 210 fixedly installed at the front end of the drying box 110 above the through slot 120. Threaded holes are formed in the fixing plate 210, and an adjusting threaded rod 220 is threadedly connected in the threaded holes. A rotating handle 230 is fixedly installed at the top of the adjusting threaded rod 220. The bottom of the adjusting threaded rod 220 is connected to a connecting plate 240 through a bearing. One end of the connecting plate 240 is fixedly installed with a barrier baffle 250.

[0039] By setting the barrier assembly 200, the ventilation volume of the through slot 120 can be adjusted according to requirements. The operator drives the adjusting threaded rod 220 to rotate in the threaded hole by rotating the rotating handle 230, so that the adjusting threaded rod 220 and the connecting plate 240 move up and down, and then drive the barrier baffle 250 to move up and down. Thereby, the amount of air heated by the annular heating lamp tube 160 escaping from the through slot 120 can be reduced, and thus the power consumption of drying the label can be reduced.

[0040] During use, the flattening assembly 300 is arranged at the rear end of the drying box 110. The traction belt is used to drive the label to pass through several groups of annular heating lamps 160 for heating and drying, and then pass through the flattening roller 330. The friction force drives the flattening roller 330 to rotate. The flattening roller 330 cooperates with the support plate 310 to flatten the surface of the dried label, preventing the label from wrinkling during the drying process and damaging the surface of the label. At the same time, the scraper 340 is inclined to scrape the surface of the flattening roller 330 to scrape off the label adhered to the surface of the flattening roller 330, preventing the label from being crushed by the rotation of the flattening roller 330. By starting the exhaust fan 470, the gas generated during the drying of the label is drawn into the movable chamber 410 through the air inlet hole 440. Using the ventilation holes 430 staggered by the U-shaped partition 420, the gas passes through the groups of ventilation holes 430 until it fills each group of U-shaped grooves, so that the gas with heat fills the entire movable chamber 410, achieving a certain heat preservation effect, and finally discharging from the air outlet hole 450 and entering the purification box 460. After being purified and filtered by the activated carbon 480, it is discharged from the air outlet pipe 490 to prevent the toxic gas from spreading everywhere and causing harm to the health of the staff. The parts not involved in this device are the same as the prior art or can be implemented using the prior art.

[0041] Although the embodiments of the present invention have been shown and described, this specific embodiment is only an explanation of the present invention and not a limitation thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations that do not contribute creatively to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
