Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a CH small package transparent paper correction device. Background Technology

[0002] CH small pack transparent paper is short for CH small box packaging transparent paper. CH small pack transparent paper is used for the outer packaging of small cigarette packs. Currently, on packaging machines in tobacco processing, the small pack transparent paper is mounted on the unwinding roller on the paper rack. After being guided and tensioned by rollers, the small pack transparent paper is conveyed to the pressure roller (e.g., ...). Figure 1 As shown, during the conveying process of small packages of transparent paper, factors such as wear of the cellophane frame and rollers, unevenness of the cellophane frame paper rings, and smoothness of the outer wall of the rollers can cause the transparent paper to shift in the left and right directions. This shifting of the transparent paper can lead to problems such as poor cutting and improper folding of the small packages of transparent paper. Utility Model Content

[0003] The purpose of this invention is to provide a CH small package transparent paper correction device, which solves the problem in the prior art that small package transparent paper is prone to deviation during transportation due to structural defects.

[0004] This utility model solves the above-mentioned technical problems through the following technical means: a CH small package transparent paper correction device, including an unwinding roller, a fixed shaft and a driving mechanism, wherein the fixed shaft is driven to rotate by the driving mechanism, and a roller is fixedly sleeved on the fixed shaft. The outer side wall of the roller is provided with a friction increasing component for increasing the friction between the roller and the transparent paper. Both ends of the roller are provided with limit rings, and the two limit rings are used to limit the width of the transparent paper.

[0005] Furthermore, the limiting ring is movably mounted on the roller, and a locking element is provided between the limiting ring and the roller.

[0007] Furthermore, the outer wall of the limiting ring is provided with a first threaded hole for the locking member to pass through, and one end of the locking member passes through the first threaded hole and abuts against the outer wall of the roller.

[0008] Furthermore, there is at least one locking element, and the first threaded hole corresponds one-to-one with the locking element.

[0009] Furthermore, the outer wall of the roller is provided with a plurality of annular grooves spaced apart along the axial direction, and the plurality of annular grooves constitute the friction increasing component.

[0010] Furthermore, both ends of the roller are provided with extension rings, and each extension ring is provided with an axial positioning component. The axial positioning component includes a positioning ring and a positioning rod. The inner end of the positioning ring is fitted inside the extension ring, and the outer end extends out of the extension ring. The outer end of the positioning ring is provided with a lug.

Example

[0024] like Figure 1-2As shown in the figure, this utility model embodiment proposes a CH small package transparent paper correction device, which is installed on a paper rack. The paper rack is provided with an unwinding roller 15, a pressure roller, and a drive mechanism. In this embodiment, the CH small package transparent paper 14 is fitted on the unwinding roller 15. The drive mechanism is connected to the pressure roller for transmission. The drive mechanism drives the pressure roller to rotate, and the rotation of the pressure roller drives the transparent paper 14 to be conveyed. In this embodiment, neither the pressure roller nor the drive mechanism is shown in the figure. The structure of the pressure roller and the drive mechanism has been fully disclosed in the prior art and will not be described in detail here. The correction device includes a roller 2 and a fixed shaft 1. The fixed shaft 1 is fixed on the paper rack. The axes of the fixed shaft 1, the unwinding roller 15, and the pressure roller are parallel. The roller 2 is coaxially mounted on the fixed shaft 1 through a bearing. The outer wall of the roller 2 is provided with a friction increasing component to increase the friction between the roller 2 and the transparent paper 14. Limiting rings 4 are provided at both ends of the roller 2. The two limiting rings 4 are used to limit the width of the transparent paper 14. With this structural design, the friction-increasing component can increase the friction between the transparent paper 14 and the roller 2, making it less likely for the transparent paper 14 to deviate during the conveying process. And when the transparent paper 14 does deviate, the limiting ring 4 can correct the deviation of the transparent paper 14, further preventing the transparent paper 14 from deviating.

[0025] A locking element 5 is provided between the limiting ring 4 and the roller 2. The outer wall of the limiting ring 4 has a first threaded hole for the locking element 5 to pass through. One end of the locking element 5 passes through the first threaded hole and abuts against the outer wall of the roller 2, thus locking and fixing the roller 2 and the limiting ring 4. In this embodiment, two locking elements 5 are symmetrically arranged around the limiting ring 4. Similarly, two first threaded holes are also provided for the two locking elements 5, and the locking elements 5 serve as tightening screws. This structural design allows the position of the limiting ring 4 on the roller 2 to be adjusted by loosening or tightening the locking elements 5, thereby adjusting the distance between the two limiting rings 4. This enables the correction device to adapt to CH small package transparent paper 14 of different widths, resulting in a simple structure, convenient installation, quick adjustment, and strong adaptability.

[0026] The outer wall of the roller 2 is provided with a plurality of annular grooves 3 at intervals along the axial direction, and the plurality of annular grooves 3 together constitute a friction-increasing component. In this embodiment, when the transparent paper 14 passes over the surface of the roller 2, the annular grooves 3 can increase the friction between the transparent paper 14 and the roller 2.

[0027] like Figure 3-4As shown, both ends of the roller 2 are integrally formed with extension rings 6. Each extension ring 6 is provided with an axial positioning component, which includes a positioning ring 7 and a positioning rod 8. The inner end of the positioning ring 7 is fitted inside the extension ring 6, and the outer end extends out of the extension ring 6. The outer end of the positioning ring 7 is fixedly provided with a lug 10. The limiting ring 4 has a second threaded hole for the positioning rod 8 to be inserted. One end of the positioning rod 8 passes through the lug 10 and is inserted into the second threaded hole. The positioning rod 8 and the lug 10, and the positioning rod 8 and the limiting ring 4 are all threadedly engaged. A fixing member 9 is provided between the positioning ring 7 and the extension ring 6.

[0028] In this embodiment, two lugs 10 are symmetrically arranged around the circumference of the positioning ring 7, and two corresponding positioning rods 8 are also provided; the fixing member 9 is a bolt, and a third threaded hole is opened at the inner end of the positioning ring 7 for the fixing member 9 to pass through. One end of the fixing member 9 passes through the third threaded hole and abuts against the inner sidewall of the extension ring 6, thereby locking and fixing the extension ring 6 and the positioning ring 7. This structural design can increase the installation stability of the limiting ring 4, so that the limiting ring 4 will not shift axially along the roller 2 during operation.

[0029] Working principle:

[0030] The roller 2 is machined with an annular groove 3 on a lathe. The limiting rings 4 are fitted onto both ends of the roller 2. The locking element 5 is loosened, and the distance between the two limiting rings 4 is adjusted to be the same as the width of the transparent paper 14. The locking element 5 is tightened, and the positioning ring 7 is fitted onto the inside of the extension ring 6 and the fixing element 9 is tightened. The limiting ring 4 and the positioning ring 7 are connected and fixed using the positioning rod 8. The transparent paper 14 is wound onto the unwinding roller 15, passes over the roller 2, and is then conveyed to the pressure roller. By machining the annular groove 3 on the roller 2, the friction of the transparent paper 14 on the roller 2 is increased. The limiting rings 4 are installed at both ends of the roller 2, and the width between the limiting rings 4 is exactly the width of the transparent paper 14. When the transparent paper 14 shifts, the limiting rings 4 can correct the shift. By setting the positioning ring 7 and the positioning rod 8, the installation stability of the limiting rings 4 is increased, ensuring that the limiting rings 4 will not shift left or right during long-term operation. The CH small package transparent paper 14 correction device provided by this utility model can solve the problem of transparent paper 14 deviation, poor cutting of transparent paper 14, and poor folding of small package transparent paper 14. The correction device of this utility model is applied to the YB55 transparent paper 14 packaging machine. Example

[0031] like Figure 5-6As shown, the difference between this embodiment and Embodiment 1 is that the friction-increasing component includes a sleeve 11, which is fixedly fitted onto the surface of the roller 2. The outer wall of the sleeve 11 has several annular grooves 3 spaced axially. A locking element 5 is provided between the limiting ring 4 and the sleeve 11. In this embodiment, both ends of the roller 2 are integrally formed with an extension ring 6. Three mounting blocks 13 are uniformly fixed circumferentially on the inner wall of the extension ring 6. A connecting component is provided between the sleeve 11 and the extension ring 6. The sleeve 11 has three through holes corresponding to the three mounting blocks 13. Each mounting block 13 has a through hole communicating with the through holes. The connecting component includes a bolt and a nut. One end of the bolt passes through the through hole and the through hole in sequence and engages with the nut to lock and fix the sleeve 11 and the extension ring 6. The limiting ring 4 is fitted onto the outer wall of the sleeve 11. This structural design features a fully detachable and fixed connection, facilitating easy assembly, disassembly, maintenance, and replacement. Multiple sleeves 11 can be fabricated, each with grooves of different sizes and types on its surface, such as equally spaced annular grooves 3, unequally spaced annular grooves 3, and oblique grooves, to accommodate various types of transparent paper 14. Furthermore, by fabricating the sleeves 11, the existing structure of the roller 2 can be preserved. This embodiment can also incorporate an axial positioning component to increase the installation stability of the limiting ring 4.
