Description

Technical Field

[0001] This utility model relates to the field of label processing technology, and in particular to a label printing, coating and drying device. Background Technology

[0002] Label printing is an indispensable part of the modern packaging industry. With the continuous increase in market demand, the efficiency and quality of label printing have become key factors. In the traditional label printing process, coating and drying are two important steps. Coating involves the uniform distribution of ink or coating materials, while drying ensures that the coating material cures quickly to avoid color bleeding or blurring. Existing equipment has certain limitations in these two steps. For example, the drying speed is insufficient to meet the needs of high-speed printing, or the coating uniformity is difficult to control, thus affecting the quality of the final product.

[0003] During the use of the drying equipment, the labels are relatively damp after printing and coating, so they need to be dried. Otherwise, the surface of the label will become too hot during the drying process, making it impossible to roll up the label directly, thus affecting efficiency. Utility Model Content

[0004] This utility model relates to a label printing, coating and drying device. Its electric push rod can adjust the position of the drying frame up and down, so that the heating tube on the drying frame can quickly dry the label below, quickly increase the label temperature, accelerate moisture evaporation, and shorten the drying time. Then, the fan blades rotate to blow away the hot air on the label, and timely discharge the hot air on the label surface to prevent moisture retention. It is convenient to roll up the dried label and improve work efficiency.

[0005] In a first aspect, this utility model provides a label printing, coating, and drying apparatus, specifically comprising: a workbench; a groove is provided at the front end of the upper end of the workbench; a fixing frame is fixedly installed at the left end of the workbench, and two through shaft holes are provided on the fixing frame; a drying chamber is fixedly installed at the top end of the workbench; a through rectangular opening is provided in the middle of the drying chamber; a drying frame is slidably installed in the inner cavity of the drying chamber, and heating tubes are evenly installed at the bottom of the drying frame;

[0006] Parallel guide blocks are fixedly installed on both sides of the drying frame; guide plates are fixedly installed at the lower ends of the rectangular openings at both ends of the drying box; a cantilever plate is fixedly installed on the upper end of the right side wall of the drying box, and a through circular hole is opened on the cantilever plate. A through drive motor is fixedly installed at the circular hole of the cantilever plate, and a ring of fan blades is fixedly installed on the shaft of the drive motor.

[0007] Furthermore, a support base is fixedly installed in the groove at the front end of the workbench, and a printing motor is fixedly installed on the upper end of the support base. A printing coating roller is mounted on the shaft of the printing motor.

[0008] Furthermore, four limiting blocks are fixedly installed at both ends of the inner sidewall of the fixed frame, and a driven shaft is rotatably installed at the shaft hole at the lower end of the fixed frame, and a squeezing roller is fitted on the driven shaft.

[0009] Furthermore, positioning strips are fixedly installed at both ends of the inner sidewall of the drying oven, and parallel guide grooves are opened at both ends of the inner sidewall of the drying oven. A sealing cover is installed at the upper end of the drying oven, and a through round hole is opened in the middle of the sealing cover.

[0010] Furthermore, a through-hole electric push rod is fixedly installed at the circular hole of the sealing cover, and a connecting plate is fixedly installed at the lower end of the electric push rod.

[0011] Furthermore, symmetrical side plates are fixedly installed on the left end of the cantilever plate, and through bolts are inserted at both ends of the side plates. An inclined connecting brace is fixedly installed on the upper end of the cantilever plate.

[0012] This utility model provides a label printing, coating, and drying apparatus, which has the following beneficial effects:

[0013] In this utility model, when the drying device is in use, the electric push rod can adjust the position of the drying frame up and down, so that the heating tube on the drying frame can quickly dry the label below, quickly increase the label temperature, accelerate moisture evaporation, and shorten the drying time. Then, the rotating fan blades will blow away the hot air on the label, and timely discharge the hot air on the label surface to prevent moisture retention. This makes it easier to roll up the dried label and improve work efficiency.

[0014] The drying frame stops moving downwards when it comes into contact with the positioning strip. The heating element on the drying frame is then activated, and the heat emitted by the heating element accelerates the evaporation of moisture, thus removing the moisture from the label more quickly. Residual moisture may reduce the adhesive performance of the label. Heating ensures that the label dries evenly, avoiding defects such as bubbles and wrinkles, and improving the overall appearance and quality of the product. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1 to 4 :

[0025] This utility model discloses a label printing, coating, and drying device, comprising: a workbench 1; a groove is provided at the front end of the upper end of the workbench 1; a fixing frame 2 is fixedly installed at the left end of the workbench 1, and the fixing frame 2 has two through shaft holes; a drying chamber 3 is fixedly installed at the top of the workbench 1; a through rectangular opening is provided in the middle of the drying chamber 3; after label printing, it passes through the rectangular opening of the drying chamber 3; positioning strips 301 are fixedly installed at both ends of the inner sidewall of the drying chamber 3; and parallel guides are provided at both ends of the inner sidewall of the drying chamber 3. A sealing cover 303 is installed at the upper end of the drying oven 302. A through-hole is formed in the center of the sealing cover 303. A through-hole electric push rod 304 is fixedly installed at the through-hole of the sealing cover 303. A connecting plate 305 is fixedly installed at the lower end of the electric push rod 304. The connecting plate 305 and the drying frame 306 are moved downwards using the electric push rod 304. The downward movement stops when the drying frame 306 comes into contact with the positioning strip 301, preventing the drying frame 306 from contacting the label. The heating element on the drying frame 306 is then activated, and the heat emitted by the heating element... Air is blown onto the labels below, drying the moisture on them. Based on the label's humidity, the position of the drying frame 306 is adjusted up and down using the electric push rod 304, facilitating rapid drying of the labels by the heating elements on the drying frame 306. The drying frame 306 is fixedly installed at the bottom of the connecting plate 305, and slides within the inner cavity of the drying chamber 3. Heating elements are evenly installed at the bottom of the drying frame 306. Parallel guide blocks 307 are fixedly installed on both sides of the drying frame 306. The guide blocks 307 slide on... In the guide groove 302, when the drying frame 306 slides up and down, the guide block 307 is restricted by the guide groove 302, and the drying frame 306 can only slide up and down to prevent the drying frame 306 from tilting when sliding up and down. Otherwise, the drying frame 306 will not be able to dry the labels below evenly and smoothly. The lower ends of the rectangular openings at both ends of the drying box 3 are respectively fixedly installed with guide plates 308; the guide plates 308 at both ends support the labels passing by. The upper end of the right side wall of the drying box 3 is fixedly installed with a cantilever plate 4, and a through round hole is opened on the cantilever plate 4.

[0026] A support base 101 is fixedly installed in the groove at the front end of the workbench 1, and a printing motor 102 is fixedly installed on the upper end of the support base 101. The shaft of the printing motor 102 passes through the shaft hole at the lower end of the fixed frame 2. A printing coating roller 103 is mounted on the shaft of the printing motor 102. There is a gap between the printing coating roller 103 and the extrusion roller 203. The label passes through the gap between the printing coating roller 103 and the extrusion roller 203. When the printing motor 102 is started, the printing coating roller 103 on the shaft will rotate, and the label between the printing coating roller 103 and the extrusion roller 203 will be printed and coated. Four limiting blocks 201 are fixedly installed at both ends of the inner sidewall of the fixed frame 2. A driven shaft 202 is rotatably installed in the shaft hole at the lower end of the fixed frame 2, and an extrusion roller 203 is mounted on the driven shaft 202.

[0027] The cantilever plate 4 has symmetrical side plates 401 fixedly installed on its left end. Bolts are inserted through both ends of the side plates 401, and these bolts are rotated and inserted into the drying oven 3 to fix and restrict the side plates 401 and the cantilever plate 4. This prevents the cantilever plate 4 from falling when touched, thus allowing it to stably support the drive motor 403. An inclined connecting brace 402 is fixedly installed at the upper end of the cantilever plate 4, and its upper end is fixedly installed on the side wall of the drying oven 3. A through-hole drive motor 403 is fixedly installed in the round hole of the cantilever plate 4. A fan blade 404 is fixedly installed on the shaft of the drive motor 403. When the drive motor 403 is turned on, the fan blade 404 rotates rapidly, causing a localized airflow that blows the hot air off the label being transported downwards, and then the label is wound up.

[0028] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, symmetrical side plates 401 are fixedly installed on the left end of the cantilever plate 4, and through bolts are inserted at both ends of the side plates 401. After removing the side plates 401 and bolts, the cantilever plate 4 is fixedly welded to the drying oven 3 to stabilize and restrict the cantilever plate 4. This prevents the cantilever plate 4 from falling off when touched, avoids the bolts from loosening and becoming unstable after long-term use, and also saves on parts costs.

[0029] The working principle of this embodiment is as follows: In use, the label passes between the printing coating roller 103 and the extrusion roller 203. When the printing motor 102 is started, the printing coating roller 103 on the shaft will rotate, printing and coating the label between the printing coating roller 103 and the extrusion roller 203. The connecting plate 305 and the drying frame 306 are moved downward using the electric push rod 304. When the drying frame 306 is in contact with the positioning strip 301, it will stop moving downward to prevent the drying frame 306 from contacting the label. The heating tube on the drying frame 306 is started, and the hot air emitted by the heating tube will blow the label below to dry the moisture on the label. According to the humidity on the label, the position of the drying frame 306 is adjusted up and down using the electric push rod 304 to facilitate the heating tube on the drying frame 306 to quickly dry the label below. The label drying will pass through the rectangular opening at the right end of the drying box 3. When the drive motor 403 is turned on, the fan blade 404 on the shaft will rotate quickly. The rotation of the fan blade 404 will drive a local airflow to blow the label conveyed below, blowing away the hot air on the label. Then the label is wound up.
