Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging equipment technology, and in particular to an arc-shaped folding device for a small box transparent paper packaging machine. Background Technology

[0002] The YB55 small box transparent paper packaging machine is used for transparent paper packaging of small boxes. The machine includes a rotating forming wheel with six stations. The station on the left side of the forming wheel is station one, and the stations on the left and right sides above the forming wheel are station two and station three, respectively. An arc-shaped folding device is provided above the forming wheel. The arc-shaped folding device includes an arc-shaped folding plate coaxially arranged with the forming wheel. The gap between the inner arc-shaped surface of the arc-shaped folding plate and the forming wheel forms a folding gap. The arc-shaped folding plate has clearance grooves at the corresponding positions of station two and station three to avoid the side sealing soldering iron.

[0003] The small cigarette pack wrapped in transparent paper enters the forming wheel from the first station on the left. The long side folding device on the side of the transparent paper folds the lower long side of the transparent paper of the small cigarette pack upward. Then the forming wheel rotates clockwise. As the small cigarette pack rotates from the first station to the second station, the inner curved face of the arc-shaped folding plate completes the folding of the upper long side of the transparent paper of the small cigarette pack. Subsequently, the small cigarette pack passes through the second and third stations in sequence. During the pause, the side sealing soldering iron completes the heat sealing operation.

[0004] In existing equipment, the arc-shaped folding plate is fixed on the equipment frame. The inner side of the arc-shaped folding plate is an arc surface, while the side of the cigarette pack is flat. During the folding process on the long side of the transparent paper of the cigarette pack, there is a gap between the arc-shaped inner side of the arc-shaped folding plate and the side of the cigarette pack. The two cannot fit together completely, resulting in defects such as looseness, wrinkles, and wavy lines in the transparent paper packaging of the cigarette pack, thus affecting the packaging quality of the cigarette pack.

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an arc-shaped folding device for a small box transparent paper packaging machine, so as to ensure that the transparent paper is always tightly attached to the side of the small box cigarette pack, thereby ensuring the packaging quality of the small box cigarette pack.

[0006] This utility model is achieved through the following technical solution: The small box transparent paper packaging machine has an arc-shaped folding device, which includes an arc-shaped folding plate fixed on the frame of the small box transparent paper packaging machine. The arc-shaped folding plate is located above the forming wheel with a gap between them. The station located to the left of the forming wheel is station one, and the station located to the left of the forming wheel is station two. The arc-shaped folding part of the arc-shaped folding plate between station one and station two is the arc-shaped folding part. The arc-shaped folding part of the arc-shaped folding plate is provided with multiple elastic folding rods. The elastic folding rods can elastically extend and retract along the radial direction of the forming wheel. The inner end of the elastic folding rod is rotatably equipped with a roller. In the natural state, the inner end of the roller protrudes from the inner side of the arc-shaped folding plate. The transparent paper of the small box cigarette pack is folded by the rollers of the multiple elastic folding rods.

[0007] As a preferred embodiment of the arc folding device of the above-mentioned small box transparent paper packaging machine, multiple elastic folding rods are arranged in multiple rows along the arc extension direction of the arc folding plate to form multiple sets of elastic folding components. Each set of elastic folding components includes several elastic folding rods arranged at intervals along the front-back direction.

[0008] As a preferred embodiment of the curved folding device for the aforementioned small box transparent paper packaging machine, each set of elastic folding components includes a mounting bracket fixedly installed on the outside of the curved folding plate, and several elastic folding rods are arranged in a front-to-back interval on the mounting bracket. The outer end of the elastic folding rod extends out of the mounting hole of the mounting bracket and is provided with an outer limiting member. The elastic folding rod is provided with an inner limiting member near its inner end. A spring is fitted on the elastic folding rod at the position between the mounting bracket and the inner limiting member. The curved folding plate is provided with a clearance groove at the position corresponding to the elastic folding rod, and the roller at the inner end of the elastic folding rod extends out from the inner end of the clearance groove.

[0009] As a preferred embodiment of the arc folding device for the aforementioned small box transparent paper packaging machine, the outer limiting component includes an outer limiting nut and a washer. The outer limiting nut is threadedly connected to the threaded end of the outer end of the elastic folding rod, and the washer is fitted onto the elastic folding rod and located between the outer limiting nut and the mounting bracket.

[0010] As a preferred embodiment of the arc-shaped folding device for the aforementioned small box transparent paper packaging machine, the inner limiting member is an inner limiting protrusion ring disposed on the elastic folding rod.

[0011] As a preferred embodiment of the arc folding device for the aforementioned small box transparent paper packaging machine, the mounting bracket is an inverted U-shaped bracket, and the front and rear ends of the mounting bracket are connected to the arc folding plate by screws.

[0012] As a preferred embodiment of the arc folding device for the aforementioned small box transparent paper packaging machine, the axis of the roller is parallel to the axis of the forming roller.

[0013] This invention has the following advantages over the prior art: This utility model provides an arc-shaped folding device for a small box transparent paper packaging machine. Multiple elastic folding rods are provided at the arc-shaped folding section of the arc-shaped folding plate. Under the action of elastic force, the elastic folding rods can slide elastically along the mounting bracket, allowing the rollers at the inner ends of the elastic folding rods to elastically float along the radial direction of the forming wheel. This ensures that the rollers always elastically and tightly adhere to the side of the small box cigarette pack, pressing the transparent paper firmly against the side of the small box cigarette pack, thus guaranteeing the folding quality of the transparent paper and improving the packaging quality of the small box cigarette pack.

These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0019] See Figures 1 to 3 This embodiment discloses an arc-shaped folding device for a small box transparent paper packaging machine. The arc-shaped folding device includes an arc-shaped folding plate 1 fixed on the frame of the small box transparent paper packaging machine. The arc-shaped folding plate 1 is mounted on the frame of the small box transparent paper packaging machine via a rear vertical plate 16. The arc-shaped folding plate 1 is located above the forming wheel 2 with a gap between them. The station located to the left of the forming wheel 2 is station 3, and the station located to the left above the forming wheel 2 is station 4. The arc-shaped folding part of the arc-shaped folding plate 1 between station 3 and station 4 is the arc-shaped folding part. The arc-shaped folding section of plate 1 is provided with multiple elastic folding rods 5. The elastic folding rods 5 can elastically extend and retract along the radial direction of the forming wheel 2. The inner end of the elastic folding rod 5 is provided with a roller 6. The axis of the roller 6 is parallel to the axis of the forming wheel 2. The roller 6 can be a bearing. The inner end of the elastic folding rod 5 is provided with a mounting shaft 7 parallel to the axis of the forming wheel 2. The inner ring of the bearing is fixedly mounted on the mounting shaft 7. In its natural state, the inner end of the roller 6 protrudes from the inner side of the arc-shaped folding plate 1. The transparent paper of the small cigarette pack 8 is folded by the rollers 6 of the multiple elastic folding rods 5.

[0020] Multiple elastic folding rods 5 are arranged in multiple rows along the arc-shaped extension direction of the arc-shaped folding plate 1, forming multiple sets of elastic folding components 9. Each set of elastic folding components 9 includes several elastic folding rods 5 arranged at intervals along the front-to-back direction. This distribution of multiple elastic folding rods 5 on the arc-shaped folding plate 1 ensures the uniformity of the pressing force on the transparent paper on the side of the cigarette pack 8, thereby ensuring the folding effect.

[0021] Each set of elastic folding components 9 includes a mounting bracket 10 fixedly installed on the outside of the arc-shaped folding plate 1. The mounting bracket 10 is an inverted U-shaped bracket, and its front and rear ends are connected to the arc-shaped folding plate 1 by screws. Several elastic folding rods 5 are arranged at intervals on the mounting bracket 10. The outer end of the elastic folding rod 5 protrudes from the mounting hole of the mounting bracket 10 and is provided with an outer limiting member. The outer limiting member includes an outer limiting nut 11 and a washer 12. The outer limiting nut 11 is threadedly connected to the threaded end of the outer end of the elastic folding rod 5. The washer 12 is fitted on the elastic folding rod 5 and is located between the outer limiting nut 11 and the mounting bracket 10. The elastic folding rod 5 is provided with an inner limiting member near its inner end. The inner limiting member is an inner limiting protrusion ring 13 provided on the elastic folding rod 5. A spring 14 is fitted on the elastic folding rod 5 at the position between the mounting bracket 10 and the inner limit member. The spring 14 is a compression spring. An avoidance groove 15 is opened on the arc-shaped folding plate 1 at the position corresponding to the elastic folding rod 5. The roller 6 at the inner end of the elastic folding rod 5 extends out from the inner end of the avoidance groove 15.

[0022] During operation, the forming wheel 2 rotates clockwise. As the small cigarette pack 8 rotates from station 3 to station 4, the inner rollers 6 of the multiple elastic folding rods 5 on the arc-shaped folding part of the arc-shaped folding plate 1 fold the long side of the transparent paper on the side of the small cigarette pack 8. Under the elastic force of the spring 14 on the elastic folding rod 5, the elastic folding rod 5 can slide elastically along the mounting hole of the mounting bracket 10, allowing the roller 6 to float elastically along the radial direction of the forming wheel 2. This ensures that the roller 6 remains elastically close to the side of the small cigarette pack 8, pressing the transparent paper firmly against the side of the small cigarette pack 8. This guarantees the folding quality of the transparent paper of the small cigarette pack 8, ensuring the subsequent heat sealing effect and thus improving the packaging quality of the small cigarette pack 8.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
