Description

Technical Field

[0001] This utility model relates to a gluing device, and more particularly to a gluing device for beer label paper production. Background Technology

[0002] The barcode printer industry primarily uses label paper, which consists of three parts: release paper, face paper, and adhesive. The release paper, also known as the backing paper, has an oily surface and acts as a barrier to the adhesive. It serves as the substrate for the face paper, ensuring that the face paper can be easily peeled off from the backing paper. The adhesive is applied to the back of the face paper, ensuring proper adhesion between the backing paper and the face paper, while also ensuring strong adhesion to the substrate after the face paper is peeled off. During label paper production, an adhesive applicator is used to apply adhesive to the face paper.

[0003] The existing glue coating device works by applying glue to the back of the label paper in dots, and then spreading the glue on the back of the label paper with a glue coating roller to achieve the effect of glue coating. However, with this method, the amount of glue on the label paper is not fixed when applying glue in dots, and there may be some areas with more glue and some areas with less glue. During the process of spreading the glue on the label paper, there may be local glue breaks or glue accumulation on the back of the label paper, which will affect the glue coating quality and reduce the processing quality of the product. Utility Model Content

[0004] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the existing glue application methods mostly involve directly applying glue to the back of the label paper and then spreading it. However, during the application process, the amount of glue may be uneven in different positions on the back of the label paper, resulting in uneven thickness of the label paper after glue application, thereby reducing the quality of glue application.

[0005] To address the aforementioned problems, this utility model provides a gluing device for beer label production, comprising an operation box. Three conveying rollers and one gluing roller are rotatably connected inside the operation box. Conveying grooves are carved into the left and lower ends of the operation box. A gluing assembly is fixedly connected to the inner wall of the operation box, positioned above the three conveying rollers. The gluing assembly includes a mounting plate fixedly connected to the inner wall of the operation box. A storage box and four compression springs are fixedly connected to the upper end of the mounting plate. The four compression springs are respectively fixedly connected to the four corners of the upper end of the mounting plate. A pressure plate is fixedly connected to the upper end of each compression spring. Four additional pressure plates are also fixedly connected to the upper end of the mounting plate. A sliding rod corresponding to four compression springs is provided. The upper end of the sliding rod moves through the adjacent compression springs and pressure plates in sequence. The inner cavity of the storage box is equipped with a squeezing block. The lower ends of multiple pressure plates are fixedly connected to the upper end of the squeezing block. A glue outlet tube is fixedly connected to the lower middle part of the mounting plate. Multiple push rods are fixedly connected to the lower end of the squeezing block. A baffle is fixedly connected to the lower end of the multiple push rods. A motor is fixedly connected to the rear end of the control box. The output end of the motor moves through the control box and is fixedly connected to a rotating rod. Multiple cams are fixedly fitted on the outer surface of the rotating rod. A glue inlet tube is provided at the front end of the control box. The rear end of the glue inlet tube is fixedly connected through the control box and fixedly connected to the storage box.

[0006] In the above-mentioned glue coating device for beer label paper production, the glue is pulsed and extruded through the mechanical linkage of cam, compression spring and extrusion block. Combined with the rebound of compression spring, a stable glue coating rhythm is formed, which makes the glue extrusion more uniform and effectively reduces glue breakage or accumulation. Moreover, the glue extrusion amount is determined by the motor speed, and the glue extrusion frequency can be flexibly adjusted to meet the glue coating needs of different production speeds.

[0007] As a further improvement of this application, the cam is located above the extrusion block, and the outer surface of the cam is in contact with the upper end of the extrusion block.

[0008] As a further improvement of this application, the two conveying rollers on the left side correspond to each other vertically, and the conveying roller on the right side corresponds to the glue-applying roller.

[0009] As a further improvement of this application, the inner wall of the storage box is fixedly connected to two symmetrically distributed inclined plates, and multiple heating rods are fixedly connected to one end of the inclined plates near the bottom wall of the storage box.

[0010] As another improvement of this application, the baffle is inclined as a whole, and the outer surface of the baffle is in contact with the inner wall of the dispensing tube.

[0011] The right-side conveyor roller is hollow, and multiple adsorption holes are drilled on the outer surface of the conveyor roller. The radial distribution of the adsorption holes on the outer surface of the conveyor roller does not exceed 60 degrees.

[0012] In summary, in practical applications, the label paper is coiled around the outer surface of multiple conveyor rollers and located below the glue coating assembly. When the motor is started, the rotating rod drives multiple cams to rotate. The cam protrusions squeeze the extrusion block, causing the compression spring to contract downwards. The extrusion block moves downwards, pushing the top rod and baffle downwards, exposing the baffle. The glue in the storage box slides down the slope of the baffle onto the surface of the label paper, thus evenly coating the label paper. The glue coating roller then spreads the glue evenly across the label paper surface. Through the mechanical linkage of the cams, compression springs, and extrusion blocks, the glue is extruded in a pulsed manner. Combined with the rebound of the compression springs, a stable glue coating rhythm is formed, resulting in more even glue extrusion and effectively reducing glue breakage or accumulation.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figure 1 and Figure 2 The diagram shows a gluing device for beer label production, comprising an operation box 1. Three conveying rollers 2 and one gluing roller 3 are rotatably connected inside the operation box 1. Conveying grooves are carved at the left and lower ends of the operation box 1 to facilitate the entry and exit of the label paper. A gluing assembly is fixedly connected to the inner wall of the operation box 1, located above the three conveying rollers 2. The two conveying rollers 2 on the left side correspond vertically to each other, and the conveying roller 2 on the right side corresponds to the gluing roller 3. The label paper is conveyed and moved by the rotation of the conveying rollers 2 and the gluing roller 3. Point A in the diagram represents the label paper.

[0027] Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The adhesive application assembly includes a mounting plate 4 fixedly connected to the inner wall of the operating box 1. A storage box 5 and four compression springs 6 are fixedly connected to the upper end of the mounting plate 4. The four compression springs 6 are respectively fixedly connected to the four corners of the upper end of the mounting plate 4. Pressure plates 7 are fixedly connected to the upper ends of the compression springs 6. Four sliding rods 8, each corresponding to one of the four compression springs 6, are also fixedly connected to the upper end of the mounting plate 4. The upper ends of the sliding rods 8 sequentially pass through adjacent compression springs 6 and pressure plates 7. An extrusion block 9 is provided inside the storage box 5. The lower ends of the multiple pressure plates 7 are fixedly connected to the upper ends of the extrusion block 9. When the cam 14 rotates, it drives the extrusion block 9 to move downwards, pressing... The spring 6's rebound facilitates the reset of the extrusion block 9. A dispensing tube 10 is fixedly connected to the lower center of the mounting plate 4. Multiple push rods 11 are fixedly connected to the lower end of the extrusion block 9. A baffle 12 is fixedly connected to the lower ends of the multiple push rods 11. The baffle 12 is inclined, and its outer surface is in contact with the inner wall of the dispensing tube 10. The up-and-down movement of the extrusion block 9 not only squeezes the glue in the storage box 5 downwards but also moves the push rods 11 and the baffle 12 downwards, causing the glue to flow down the slope of the baffle 12 onto the label. A motor 18 is fixedly connected to the rear end of the operation box 1. Those skilled in the art can select according to actual needs. Select a suitable model of motor 18, such as Y2-63M1-2-0.18KW. The output end of motor 18 movably passes through the control box 1 and is fixedly connected to a rotating rod 13. Multiple cams 14 are fixedly sleeved on the outer surface of the rotating rod 13. The cams 14 are located above the extrusion block 9, and the outer surface of the cams 14 is in contact with the upper end of the extrusion block 9. The rotation of motor 18 can drive the cams 14 to rotate, thereby cyclically extruding the extrusion block 9. Each rotation of cam 14 can extrude a certain amount of glue. The faster the speed of motor 18, the higher the extrusion frequency, and thus the more glue is extruded. The amount of glue extruded is determined by the speed of motor 18. The system allows for flexible adjustment of the glue extrusion frequency, catering to different glue application needs at varying production speeds. The front end of the control box 1 is equipped with a glue inlet pipe, the rear end of which is fixedly connected to the control box 1 and the storage box 5. Two symmetrically distributed inclined plates 15 are fixedly connected to the inner wall of the storage box 5. Multiple heating rods 16 are fixedly connected to one end of the inclined plates 15 near the bottom wall of the storage box 5. Those skilled in the art can select appropriate heating rods 16 according to actual needs, such as Q10X80. During glue dispensing, the heating rods 16 can be activated to heat the glue in the storage box 5, effectively preventing the glue from hardening and maintaining its fluidity.

[0028] When using this adhesive coating device, the label paper is coiled around the outer surface of multiple conveyor rollers 2 and located below the adhesive coating assembly. Starting the motor 18 causes the rotating rod 13 to drive multiple cams 14 to rotate. The protruding parts of the cams 14 press against the extrusion block 9, causing the compression spring 6 to contract downwards. The extrusion block 9 moves downwards, pushing the top rod 11 and the baffle 12 downwards, exposing the baffle 12. The adhesive in the storage box 5 slides down the slope of the baffle 12 onto the surface of the label paper, thus evenly coating the label paper surface. As the cams 14 rotate, the protruding parts of the cams 14 no longer... When the extrusion block 9 comes into contact with the surface of the compression spring 6, the compression spring 6 returns to its original position, causing the baffle 12 to move upward until it is located inside the glue dispensing tube 10, sealing the bottom of the glue dispensing tube 10. This allows the glue to be evenly applied to the surface of the label paper. The glue roller 3 then spreads the glue evenly across the surface of the label paper. Through the mechanical linkage of the cam 14, the compression spring 6, and the extrusion block 9, the glue is extruded in a pulsed manner. Combined with the return of the compression spring 6, a fixed amount of glue can be extruded, thus forming a stable glue dispensing rhythm. This makes the glue dispensing more uniform and effectively reduces the occurrence of glue breakage or accumulation.

[0029] Second implementation method:

[0030] This embodiment adds an adsorption hole 17 to the first embodiment, while the rest remains the same as the first embodiment.

[0031] Figure 8 and Figure 9 As shown: the conveyor roller 2 on the right is hollow, and multiple adsorption holes 17 are drilled on the outer surface of the conveyor roller 2. The radial distribution of the adsorption holes 17 on the outer surface of the conveyor roller 2 does not exceed sixty degrees.

[0032] When the label paper is coated by the coating roller 3, the front end of the conveying roller 2 on the right is connected to the air source. The air source absorbs the gas inside the conveying roller 2. When the multiple adsorption holes 17 are covered by the label paper, the label paper is adsorbed by negative pressure. When the coating roller 3 coats the surface of the label paper, it effectively prevents the label paper from shifting, thereby effectively improving the stability of the label paper when it is coated with glue.

[0033] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
