Description

Technical Field

[0001] This utility model relates to cigarette packaging equipment, specifically to a pre-pressing device for the end of the transparent paper of a packaging machine carton. Background Technology

[0002] The packaging process for cigarette cartons using transparent paper is as follows: Cigarette cartons without transparent paper are wrapped with pre-cut transparent paper via the first elevator, with the transparent paper folded along the center seam. They are then conveyed to the cigarette conveyor channel and pushed in by a pusher, with the ends of the transparent paper folded during this process. The center seam is ironed inside the channel. After completion, the cartons are lifted by the second elevator to the next stage for end ironing. The function of the cigarette support cover in the conveyor channel is to hold the wrapped cigarette cartons in place, ensuring smooth movement within the channel and facilitating center seam ironing.

[0003] In the original equipment, before the end folding ironing process, the end transparent paper of the cigarette pack did not undergo any pressing process after the center seam ironing. Because the transparent paper has a certain shrinkage characteristic after the center seam ironing, the end transparent paper of the cigarette pack will be slightly deformed after the center seam ironing process. If it goes directly into the end folding ironing process, it may cause the end transparent paper to be misaligned or deformed, thus making the packaging quality of the cigarette pack transparent paper unqualified. Utility Model Content

[0018] The embodiments of this utility model are described in detail below. 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 a pre-compression device for the end of the transparent paper of a packaging machine. A cigarette support cover beam 2 is horizontally arranged above the cigarette conveying channel 1 of the packaging machine in the left-right direction. The cigarette support cover beam 2 is equipped with a pre-compression device, which includes a bracket 3 and two sets of pre-compression components 4 on the left and right. The bracket 3 is installed on the cigarette support cover beam 2. A cylinder 5 is provided on the cigarette support cover beam 2. The piston rod of the cylinder 5 extends upward and is connected to the bracket 3. The extension and retraction of the piston rod of the cylinder 5 drives the bracket 3 to move vertically. The bracket 3 has two guide holes on the left and right. The cigarette support cover beam 2 has two guide posts on the left and right. The two guide holes of the bracket 3 are slidably engaged with the two guide posts 6 to guide the vertical movement of the bracket 3. Mounting plates 7 are provided at the left and right ends of one side of the bracket 3. The mounting plates 7 have a vertical flange at the end away from the bracket 3.

[0020] The left and right pre-compression components 4 are respectively installed on the vertical flanges of the mounting plates 7 at the left and right ends of the bracket 3. The left and right pre-compression components 4 press and support the top left and right ends of the cigarettes 22 conveyed in the cigarette conveying channel 1.

[0021] The pre-compression assembly 4 includes a connecting seat 8 mounted on a bracket 3. A connecting plate 9 is located at the center of the top of the connecting seat 8. The connecting seat 8 and the connecting plate 9 are integrally formed to create an inverted T-shaped seat. A vertically extending first oblong hole 10 is formed on the connecting plate 9. A first bolt 11 passes through the first oblong hole 10 and is tightened onto the vertical flange of the mounting plate 7 on the corresponding side, thus installing the connecting seat 8 onto the bracket 3. By adjusting the position of the first bolt 11 in the first oblong hole 10, the overall height of the pre-compression assembly 4 can be adjusted to ensure it is at a suitable height. A support seat 12 is movably mounted at the bottom of the connecting seat 8, and the support seat 12 can elastically float vertically relative to the connecting seat 8. Specifically, the support base 12 has two first screws 13 at its top. Each first screw 13 passes upward through a hole in the connecting base 8 and is screwed with a first nut 14, suspending the support base 12 on the connecting base 8. Springs 15 are fitted onto each of the two first screws 13, with their upper and lower ends elastically pressing against the connecting base 8 and the support base 12. By adjusting the position of the first nut 14 on the first screw 13, the preload of the spring 15 can be adjusted, thereby adjusting the pressure of the preload roller 17 and preload soldering iron 16 on the cigarette pack 22 at the bottom of the support base 12. This elastic floating structure ensures that the preload soldering iron 16 and preload roller 17 maintain elastic contact with the cigarette pack 22, guaranteeing a tight fit while preventing damage to the cigarette pack 22.

[0022] The support base 12 has a pre-pressure soldering iron 16 and a pre-pressure roller 17 arranged side by side at the bottom. The pre-pressure roller 17 is rotatably mounted on the bottom of the support base 12. The top of the pre-pressure soldering iron 16 has two second screws 18. The bottom of the support base 12 has a mounting plate 19 with two mounting holes for the two second screws 18 to pass through. Limiting nuts 20 are screwed onto the second screws 18 on the upper and lower sides of the mounting plate 19, respectively. The pre-pressure roller 17 presses and supports the cigarette pack 22, and the pre-pressure soldering iron 16 irons the cigarette pack 22. The rear end of the pre-pressure soldering iron 16 has a rounded corner 21 to allow the cigarette pack 22 to be smoothly and without damage guided under the pre-pressure soldering iron 16. By adjusting the position of the two limiting nuts 20 on the second screws 18, the height of the pre-pressure soldering iron 16 can be finely adjusted to ensure that the pre-pressure soldering iron 16 is at a suitable height.

[0023] When the equipment is working normally, the piston rod of cylinder 5 is in the retracted state. The cigarette packs 22 are conveyed from back to front in the cigarette pack conveying channel 1. When they reach the pre-pressing device, they first contact the pre-pressing roller 17, which presses the transparent paper at the end of the cigarette pack 22. Then they contact the pre-pressing iron 16, which uses a temperature of 50℃~70℃ to iron the transparent paper at the end of the cigarette pack 22 at a low temperature. This ensures that the transparent paper at the end of the cigarette pack 22 is flatter before entering the next process, thus ensuring the quality of the subsequent folding and ironing of the transparent paper at the end of the cigarette pack 22.

[0024] When the equipment stops, the piston rod of cylinder 5 extends upward, driving the bracket 3 to lift, thereby lifting the two sets of pre-pressing components 4 away from the cigarette pack 22, preventing the pre-pressing soldering iron 16 from being in contact with the transparent paper of the cigarette pack 22 for a long time and causing damage to the transparent paper.

[0025] 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.
