Description

Technical Field

[0001] This invention relates to the field of equipment for processing and forming strip-shaped sheet materials, and specifically to an adhesive splicing device. Background Technology

[0002] In the tobacco production industry, raw materials in strip form are frequently encountered; examples include traditional cigarette paper and cigarette box lining paper; and the raw materials for new low-temperature non-combustible tobacco, such as thin tobacco leaves and PLA material in the cooling stage. A key issue with strip materials is the need to remove the old strip and replace it with a new one after the old one is used up. Currently, equipment must be shut down during strip material changes, inevitably impacting production efficiency. Due to limitations in machinery and manpower, raw material rolls cannot be made very large. Furthermore, with the continuous upgrading of tobacco machinery leading to increased production speeds, the downtime caused by frequent strip material changes severely restricts improvements in production efficiency.

[0003] For tobacco manufacturers, there is an urgent need for a splicing device that can automatically connect nearly depleted strips of material to new strips end-to-end, thereby saving downtime caused by material changes and ensuring production efficiency. Existing splicing devices include the adhesive overlap device on the KDF2 filter rod forming machine, which achieves the splicing of cigarette paper through ingenious mechanical structure and electrical control. However, this splicing method has its limitations; the complex mechanical structure and high-speed swinging blades restrict it to applications with relatively narrow strips of material. Cigarette box lining paper and thin tobacco sheets for new tobacco products have widths exceeding 100mm. The overlap device on the KDF2 filter rod forming machine is clearly inadequate for such wide raw materials. Therefore, an alternative overlap structure is needed to handle wider strips and adapt to a wider range of applications. Summary of the Invention

Both new and old materials are placed between the blade and the cylinder assembly. The first segment of the new strip material is wound around the paper traction assembly. The connecting plate moves towards the adhesive suction plate. The cylinder assembly and the blade assembly work together to cut the new and old materials together. Simultaneously, the paper traction assembly pulls away the first segment of the new material, pressing the lower half of the old material and the upper half of the new material onto the adhesive sheet, thus achieving the splicing of the new and old strip materials. The widths of the cylinder assembly, adhesive suction assembly, and blade assembly can be adjusted according to the materials to be spliced, with a maximum width exceeding 100mm, thereby enabling the splicing of wide-width materials and expanding the application environment of the adhesive splicing device.

The first cylinder bracket 14 is mounted on the splicing mounting plate 40, the first cylinder 15 is connected to the first cylinder bracket 14, and the connecting plate 11 is connected to the first cylinder 15. The glue suction assembly 20 is mounted on the splicing mounting plate 40. The glue suction assembly 20 includes a glue suction plate 21 and a first support shaft 22. The glue suction plate 21 is arranged parallel to the connecting plate 11, and when the cylinder assembly 10 moves, the glue suction plate 21 can abut against the blade plate 12 and the negative pressure plate 13. The first support shaft 22 is vertically arranged on the splicing mounting plate 40, and the glue suction plate 21 can rotate around the first support shaft 22. The blade holder 34 and blade holder assembly 30 are arranged between the cylinder assembly 10 and the glue suction assembly 20. The blade holder 34 and blade holder assembly 30 include a blade 31.

[0037] Specifically, the cylinder assembly 10, the glue suction assembly 20, the knife holder 34, the knife holder assembly 30, and the paper head traction assembly 60 are all disposed on the same side of the splicing mounting plate 40. The working process of the present invention includes: the new material and the old material to be spliced ​​are placed between the cylinder assembly 10 and the knife holder assembly 30; before splicing, the blade 31 is adjusted to a horizontal position; after the glue suction plate 21 absorbs the film, the first support shaft 22 is rotated so that the glue suction plate 21 is parallel to the connecting plate 11; the paper head of the new material is connected to the paper head traction assembly 60 and remains stationary; under the action of the first cylinder 15, the connecting plate 11 moves towards the glue suction assembly 20. During the movement of the connecting plate 11, the negative pressure plate 13 first contacts and adsorbs the old material; as the connecting plate 11 moves, the blade 31 enters the groove of the connecting plate 11, and the blade plate 12 and the blade 31 work together to cut the new material and the old material at the same time. Under the traction force of the paper traction component 60, the first section of the new material is dragged away; then the blade 31 enters the groove on the connecting plate 11, and the blade plate 12 and the negative pressure plate 13 approach the adhesive suction plate 21, squeezing the upper end of the new material and the lower end of the old material onto the adhesive film adsorbed by the adhesive suction plate 21, thus achieving the splicing of the new material and the old material.

[0038] In this embodiment, the widths of the cylinder assembly 10, glue suction assembly 20, knife holder assembly 30, and paper traction assembly 60 can be set and adjusted according to the width of the materials to be overlapped. When overlapping materials of a large width is required, the widths of the cylinder assembly 10, glue suction assembly 20, knife holder assembly 30, and paper traction assembly 60 can be set to a suitable width. This adhesive overlap device is designed to be suitable for overlapping materials of different widths, thus improving the applicability of the overlap device.

[0039] In some embodiments of the present invention, the connection method between the first cylinder bracket 14 and the splicing mounting plate 40 can be riveting, welding, bolting, etc. The connection method between the first cylinder 15 and the first cylinder bracket 14 includes, but is not limited to, screw connection.

[0040] In this embodiment, a cylinder is used to drive the connecting plate 11 to move, resulting in smooth power output.

[0041] Furthermore, in some embodiments of the present invention, the connecting plate 11 is provided with a groove and an annular groove, and the negative pressure plate 13 disposed below the groove is connected to the connecting plate 11. A cavity is formed between the negative pressure plate 13 and the annular groove of the connecting plate 11.

An air pipe connector is installed on the air extraction hole, and the air pipe connector is connected to the outside through an air pipe. The negative pressure plate 13 is provided with a plurality of vent holes, and the vent holes are connected to the cavity between the negative pressure plate 13 and the connecting plate 11.

[0042] In this embodiment, the air tube can be connected to an external vacuum generator. When the vacuum generator is working, it removes the air from the cavity, so that the negative pressure plate 13 has negative pressure and can adsorb materials.

[0043] In other embodiments of the present invention, the adhesive suction assembly 20 includes a first support shaft 22; the first support shaft 22 is vertically and rotatably disposed on the splicing mounting plate 40, and the adhesive suction plate 21 is fixedly connected to the first support shaft 22. In this embodiment, the rotation of the first support shaft 22 drives the adhesive suction plate 21 to rotate, thereby changing the position of the adhesive suction plate 21.

[0044] In some embodiments of the present invention, the adhesive suction assembly further includes a first flip plate 23, a mounting bracket 24, and an outer bracket 25. The first flip plate 23 is connected to the first support shaft 22 and the adhesive suction plate 21. The mounting bracket 24 is disposed on the splicing mounting plate 40. The outer bracket 25 is connected to the mounting bracket 24 and the end of the first support shaft 22 away from the splicing mounting plate 40.

[0045] In this invention, the first flip plate 23 serves as a horizontal and vertical limiter to prevent positional deviation of the adhesive suction plate 21 during rotation; the outer bracket 25 and the mounting bracket 24 prevent displacement of the adhesive suction assembly during operation and increase the overall stability of the adhesive suction assembly.

[0046] In a further embodiment of the present invention, the first flipping plate 23 is connected to the adhesive suction plate 21 and the first support shaft 22. The first support shaft 22 is a hollow shaft with multiple elongated slots in the radial direction. The first flipping plate 23, the adhesive suction plate 21, and the elongated slots of the first support shaft 22 form a second cavity. The adhesive suction plate 21 is provided with multiple vent holes communicating with the second cavity. One end of the first support shaft 22 is equipped with a second air pipe connector, which communicates with the outside to allow gas exchange between the second cavity and the outside environment.

[0047] In this embodiment, the gas in the second cavity is discharged from the second cavity through the second air pipe connector, so that the adhesive suction plate 21 has negative pressure adsorption.

[0048] In some embodiments of the present invention, the tool holder assembly 30 further includes a cylinder base 32, a second cylinder bracket 33, a tool holder 34, a first rotating shaft 35, a first connecting shaft 36, a second flip plate 37, and a second cylinder 38. The cylinder base 32 is mounted on the back side of the splicing mounting plate 40, the back side of which is the side opposite to the side where the cylinder assembly 10 is mounted. Two second cylinder brackets 33 are provided on the cylinder base 32. The splicing mounting plate 40 has a through hole to allow the second cylinder 38 to pass through it. One end of the second cylinder 38 is coupled to the second cylinder bracket 33, and the other end of the second cylinder 38 is connected to the first connecting shaft 36.

The tool holder 34 has a round hole through which the first rotating shaft 35 passes; the first connecting shaft 36 is connected to the second flip plate 37, and the blade 31 is arranged between the second flip plate 37 and the first rotating shaft 35. The movement of the second cylinder 38 causes the blade 31 to rotate with the first rotating shaft 35.

[0049] In this embodiment, the movement of the second cylinder 38 causes the blade 31 to rotate with the first rotating shaft 35, so that the blade 31 has at least a horizontal position and a vertical position. When the blade 31 is in the horizontal position, the blade 31 can fully enter the groove to achieve cutting of new and old materials.

[0050] In other embodiments of the present invention, a through hole is provided on the splicing mounting plate 40 to allow the blade 31 to move in a direction perpendicular to the splicing mounting plate 40. When splicing new and old materials is required, the blade 31 moves between the cylinder assembly 10 and the adhesive suction assembly 20. After splicing is completed, the blade 31 moves towards the back of the splicing mounting plate 40, that is, the blade 31 is removed from between the cylinder assembly 10 and the adhesive suction assembly 20.

[0052] Specifically, one end of the first torsion spring 64 is fixed to the splicing mounting plate 40, and the other end is connected to the trigger plate 53, allowing the trigger plate 53 to rotate around the second rotating shaft 52. When splicing new and old materials, the trigger rod 16 contacts the trigger plate 53, and the trigger plate 53 is pushed by the trigger rod 16, thereby rotating clockwise around the second rotating shaft 52. The rotation of the trigger plate 53 causes the end of the trigger plate 53 that contacts the paper head traction assembly 60 to move away from the paper head traction assembly 60, thereby reducing the friction between the paper head traction assembly 60 and the trigger plate 53, causing the paper head traction assembly 60 to move and pull the paper head portion of the new material away from between the cylinder assembly 10 and the glue suction assembly 20.

[0053] In some embodiments of the present invention, the paper traction assembly 60 further includes a second support shaft 62, a power storage disk 63, a second torsion spring 51, and a paper traction rod 65; the second support shaft 62 is mounted on the splicing mounting plate 40, the power storage disk 63 is mounted on the second support shaft 62, the second support shaft 62 is connected to the second torsion spring 51, the other end of the second torsion spring 51 is connected to the power storage disk 63, the outer circumference of the power storage disk 63 abuts against the trigger plate 53 so that the paper traction assembly 60 is stationary, the first roller 61 is supported by a one-way bearing, and the first roller 61 has an axially formed long groove for placing the paper traction rod 65.
