Description

Technical Field

[0001] The utility model relates to the technical field of liquid packaging equipment, in particular to a label conveying device. Background Art

[0002] The label conveying device usually includes: a label transport power roller mechanism and a pressure roller mechanism. The label transport power roller mechanism includes a label transport power roller and a power mechanism for driving the label transport power roller to rotate. The outer wall of the label transport power roller is provided with a mesh pattern. The power mechanism adopts a synchronous pulley mechanism. The pressure roller mechanism includes: a pressure roller and a pressure-blocking drive mechanism for pressing the pressure roller on the label transport power roller.

[0003] During the long-term label conveying process, it was found that the label conveying device of the above structure has the following defects: First, the mesh pattern on the outer wall of the label conveying power roller is formed by the intersection of two oblique straight lines arranged in opposite directions. Only when the oblique straight lines in the two directions are evenly arranged can the label be conveyed smoothly. Otherwise, the label will deviate obliquely upward or downward during the conveying process. This requires very high processing accuracy of the mesh pattern, which greatly increases the processing cost of the label conveying power roller. Second, although the mesh pattern on the outer wall of the label conveying power roller effectively increases the friction force, it also has a strong cutting effect on the rubber roller material of the label conveying pressure roller, which greatly increases the wear of the pressure roller and effectively shortens its service life. Third, in addition, the mesh pattern will easily cause indentations on the surface of the label, thereby affecting the quality of the packaging. Utility Model Content

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] like Figures 1 to 4As shown, a label conveying device includes: a label conveying power roller mechanism 1 and a pressure roller mechanism 2. The label conveying power roller mechanism 1 includes a label conveying power roller 11 and a label conveying power mechanism for driving the label conveying power roller 1 to rotate. The pressure roller mechanism 2 includes a pressure roller 21 and a pressure-blocking drive mechanism for pressing the pressure roller 21 against the outer wall of the label conveying power roller 1. In this embodiment, the outer wall of the label conveying power roller 11 is provided with strip-shaped straight grooves 3. The structure of the straight grooves 3 includes: a plurality of straight grooves 31 evenly spaced around the circumference of the label conveying power roller 11 and recessed inwardly, each straight groove 31 being arranged parallel to the axis of the label conveying power roller 11.

[0019] The cross section of each straight groove 31 is in the shape of a V-shape or a bowl with the opening gradually increasing from the inside to the outside. Figure 4 As shown, the bowl is Figure 3 The size of the opening b of each straight groove 31 is 0.3 mm to 0.5 mm, the depth of each straight groove 31 is 0.2 mm to 0.4 mm, and the spacing a between each two adjacent straight grooves 31 is 1.3 to 1.5 mm.

[0020] In this embodiment, the label transport power mechanism includes a servo motor 4, which drives the label transport power roller 11 to rotate through a reduction gear box 5. The servo motor 4 and the reduction gear box 5 are fixedly mounted on the frame 10.

[0021] In this embodiment, the structure of the pressure-blocking drive mechanism includes: a pressure roller mounting base 6 disposed on a frame 10; a pressure roller 21 disposed parallel to the label-transporting power roller 11; a drive shaft 212 connected to the upper and lower ends of the pressure roller shaft 211 of the pressure roller 21; and the upper and lower drive shafts 212 extending parallel to and extending through guide holes 213 disposed at the upper and lower ends, respectively, of the guide pressure roller mounting base 6. Each drive shaft 212 is driven by a cylinder 214. The piston rods of the two cylinders 214 extend outward, driving the pressure roller 21 toward the label-transporting power roller 11 until it abuts against the outer wall of the label-transporting power roller 11. Driven by the cylinders 214, the pressure roller 21 can tightly abut against the label-transporting power roller 11, thereby generating a clamping force for conveying labels.

[0022] In this embodiment, strip-shaped straight lines 3 are used on the outer wall of the label transport power roller 11. Each straight groove 31 forming the straight lines 3 is arranged parallel to the axis of the label transport power roller 11. Compared with the mesh lines, the straight lines have only one type of lines parallel to the axis direction of the label transport power roller 11. Therefore, it can effectively prevent the label from deflecting upward or downward during the transportation process. At the same time, compared with the mesh lines, the processing accuracy requirements of the straight lines are relatively lower, which can effectively reduce the production cost of the equipment.

[0023] The straight grooves 31 forming the straight lines are recessed inward. Since the pressure roller 21 is made of rubber, which has a certain degree of deformation, when the pressure roller 21 presses against the label transport roller 11, the contact area with the label transport roller 11 deforms and embeds into the straight grooves 31 due to the pressure. This effectively increases the clamping force between the label transport roller 11 and the pressure roller 21, thereby ensuring more stable label transport. Furthermore, compared to the mesh pattern, the straight lines have a much less cutting effect on the pressure roller, which effectively reduces wear on the pressure roller, thereby significantly extending the service life of the pressure roller and reducing production costs.

[0024] In this embodiment, the dimension b at the opening of each straight slot 31 is 0.3mm to 0.5mm, and the depth of each straight slot 31 is 0.2mm to 0.4mm. Using straight slots 31 of this width and depth ensures stable and reliable label delivery while effectively reducing label indentation. The spacing between adjacent straight slots 31 is controlled to be 1.3 to 1.5mm, ensuring that the label transport power roller 11 and the pressure roller 21 provide a stable clamping force.

[0025] In addition, in the present application, the label conveying power roller 11 is composed of a servo motor 4 and a reduction gearbox 5. The label conveying power mechanism of this structure not only has stable power, but also greatly reduces the volume, effectively simplifying the structure of the entire label conveying device.

[0026] Therefore, the advantages of the present invention are: 1. The use of a straight-grained label conveying roller 11 not only ensures stable label delivery but also significantly reduces cutting action on the pressure roller, thereby effectively reducing wear on the pressure roller and extending its service life. 2. It not only reliably clamps the label but also effectively reduces the indentation of the label. 3. It is compact, has a simplified structure, and provides stable label delivery.
