Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a maintenance platform for a transparent paper cutting component of a packaging machine. Background Technology

[0002] The outer packaging of individual cigarette boxes or entire cartons of cigarettes mostly uses transparent paper packaging machines for heat sealing with transparent paper. Currently, transparent paper packaging machines consist of cigarette pack input, pull line supply, transparent paper supply, packaging forming and heat sealing, and cigarette pack output. The transparent paper supply section includes several parts such as a transparent paper support, a transparent paper conveying assembly, and a cutting assembly. During the transparent paper packaging process, the transparent paper conveying assembly conveys the transparent paper downwards from the transparent paper support, and the traction roller of the cutting assembly cuts the transparent paper into fixed lengths and sends them to the packaging position in front of the packaging forming wheel. The axes of the fixed blade and the movable blade in the cutting assembly are staggered by 3 degrees. When the movable blade rotates, it forms a point-by-point shearing from the inside out with the fixed blade, cutting it into individual transparent paper sheets.

[0003] During the use of packaging machines, wear and tear on the traction rollers or blades may occur, requiring maintenance of the shearing assembly. Currently, operators usually disassemble the shearing assembly onto the workbench for repair or replacement of parts, and then install the repaired shearing assembly back onto the packaging machine for testing. If problems occur, it must be disassembled again for maintenance, which is time-consuming and inefficient. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] like Figures 1 to 5 As shown in the figure, the maintenance platform for the transparent paper cutting component of the packaging machine according to this utility model embodiment includes a frame 1, a drive mechanism 2, and a cutter assembly 3. The frame 1 has a first side 11 arranged along a first direction (the first direction is the X direction shown in the figure), and a mounting base 12 is provided on the first side 11. The drive mechanism 2 is disposed on the first side 11, and the drive mechanism 2 and the mounting base 12 are spaced apart along a second direction (the second direction is the Y direction shown in the figure). The cutter assembly 3 includes a cutter holder 31, a traction roller 32, a cutter shaft 33, and a moving cutter. The traction roller 32 and the cutter shaft 33 are rotatably disposed on the cutter holder 31, and the rotation axes of the traction roller 32 and the cutter shaft 33 both extend along the second direction. The moving cutter is disposed on the outer periphery of the cutter shaft 33. The cutter holder 31 and the mounting base 12 are detachably connected, so that the traction roller 32 and the cutter shaft 33 can be connected to the drive mechanism 2 and driven by the drive mechanism 2. The first direction and the second direction are arranged perpendicularly.

[0031] Understandably, by setting a drive mechanism 2 on the frame 1, the maintained cutter assembly 3 can be detachably installed on the mounting base 12 to connect the traction roller 32 and the cutter shaft 33 with the drive mechanism 2. The drive mechanism 2 is used to drive the traction roller 32 and the cutter shaft 33 to rotate to simulate the operating state of the cutter assembly 3 in the packaging machine, to check the maintenance quality of the cutter assembly 3, reduce the frequency of repeated disassembly of the cutter assembly 3, reduce the time spent troubleshooting the cutter assembly 3, and effectively improve the maintenance efficiency of the cutter assembly 3.

[0032] Optionally, two, three, or more sets of cutter assemblies 3 can be prepared so that when the cutter assembly 3 malfunctions, the faulty cutter assembly 3 removed from the packaging machine can be placed on the maintenance platform for the transparent paper cutting assembly of the packaging machine for maintenance and inspection. At the same time, the prepared and maintained cutter assembly 3 can be installed into the packaging machine for operation. By quickly replacing and simultaneously maintaining multiple sets of cutter assemblies 3, the method of on-site maintenance and debugging of a single cutter assembly 3 can be replaced, which can effectively ensure maintenance efficiency while also fully ensuring the production efficiency of the packaging machine.

[0033] Furthermore, such as Figure 2 and Figure 3 As shown, the mounting base 12 includes a fixing part 121 and a mounting part 122. The fixing part 121 is disposed on the first side 11. The mounting part 122 protrudes from the side of the fixing part 121 away from the first side 11. The length of the mounting part 122 extends along the second direction. The tool holder 31 includes a base body 311 and a connecting part 312. The traction roller 32 and the tool shaft 33 are rotatably disposed on the base body 311. The base body 311 is provided with two connecting parts 312 at intervals along the vertical direction (the vertical direction is the Z direction shown in the figure) facing the mounting base 12. The length of the connecting part 312 extends along the second direction. The two connecting parts 312 are spaced apart to form a mounting groove 313. The mounting part 122 is inserted into the mounting groove 313. The first direction and the second direction are both perpendicular to the vertical direction. By utilizing the cooperation between the mounting part 122 and the mounting groove 313, a quick connection between the tool holder 31 and the mounting base 12 can be achieved. The lengths of both the mounting part 122 and the mounting groove 313 extend along the second direction, which facilitates the adjustment of the position of the tool holder 31 along the second direction, thereby improving the connection accuracy between the traction roller 32, the cutter shaft 33 and the drive mechanism 2. At the same time, by restricting the mounting part 122 in the vertical direction through the mounting groove 313, the connection stability between the mounting base 12 and the tool holder 31 can be improved, and the tool holder 31 can be prevented from wobbling in the vertical direction.

[0034] Specifically, at least one of the two connecting portions 312 has a through hole extending vertically. A first threaded hole is provided on the mounting portion 122 opposite to the through hole. A first bolt passes through the through hole and is screwed into the first threaded hole to fix the connecting portion 312 to the mounting portion 122. This connection via bolt and threaded hole ensures a tight fixation between the connecting portion 312 and the mounting portion 122, effectively preventing loosening between components, improving the connection stability between the mounting base 12 and the tool holder 31, ensuring no accidental detachment during inspection and operation, and providing high convenience for disassembly and assembly through simple bolt tightening, saving time and reducing tool requirements. In this embodiment, the through hole is only provided on the lower connecting portion 312. Of course, in addition to providing a through hole on the lower connecting portion 312, a through hole can also be provided on the upper connecting portion 312, or both connecting portions 312 can have through holes.

[0035] Furthermore, combining Figure 5 As shown, the cutter assembly 3 also includes first rollers 34. A first limiting groove 1221 is recessed on the top side of the mounting portion 122, and the first limiting groove 1221 penetrates both sides of the mounting portion 122 along the second direction. Multiple first rollers 34 are rotatably connected to the bottom of the connecting portion 312 located above. All the first rollers 34 are spaced apart along the second direction, and the rotation axis of the first rollers 34 extends along the first direction. The first rollers 34 are slidably disposed at the bottom of the first limiting groove 1221. Through the arrangement of multiple first rollers 34 and their cooperation with the first limiting groove 1221, on the one hand, the first rollers 34 are effectively limited from excessive deviation or derailment due to uneven force or external force, ensuring the installation guidance of the cutter holder 31; on the other hand, the frictional wear between the cutter holder 31 and the mounting base 12 is effectively reduced, improving the service life of both the cutter holder 31 and the mounting base 12.

[0036] Preferably, the cutter assembly 3 further includes a second roller 35. A second limiting groove 1222 is recessed on the bottom side of the mounting portion 122, and the second limiting groove 1222 passes through both sides of the mounting portion 122 along the second direction. A plurality of second rollers 35 are rotatably connected to the top of the connecting portion 312 located below. All the second rollers 35 are spaced apart along the second direction, and the rotation axis of the second rollers 35 extends in the vertical direction. The second rollers 35 are slidably connected to the two groove walls of the second limiting groove 1222 arranged along the first direction. By limiting the second rollers 35 through the two groove walls of the second limiting groove 1222 arranged along the first direction, the wobbling of the cutter holder 31 along the first direction is effectively prevented, further improving the connection stability between the cutter holder 31 and the mounting base 12. Moreover, the setting of the second rollers 35 can effectively reduce the frictional loss between them and the second limiting groove 1222, ensuring the service life of the cutter holder 31 and the mounting base 12.

[0037] In some embodiments, such as Figure 3and Figure 4 As shown, the drive mechanism 2 includes a mounting frame 21 and a first drive assembly 22 and a second drive assembly 23 disposed on the mounting frame 21. The first drive assembly 22 can be connected to the cutter shaft 33, and the second drive assembly 23 can be connected to the traction roller 32. The mounting frame 21 is provided with a first waist-shaped hole 211, the length of which extends along a second direction. The first side 11 of the frame 1 is provided with a second threaded hole. A second bolt passes through the first waist-shaped hole 211 and is screwed into the second threaded hole to fix the mounting frame 21 to the frame 1. By driving the cutter shaft 33 and the traction roller 32 independently through the first drive assembly 22 and the second drive assembly 23, the movement of the cutter shaft 33 and the traction roller 32 can be controlled independently, ensuring that different components can work in coordination. By providing a first waist-shaped hole 211 extending in the second direction on the mounting bracket 21, the mounting bracket 21 has adjustment space in the second direction, improving the installation flexibility of the drive mechanism 2, so that it can be finely adjusted according to the actual situation to meet different installation requirements. Moreover, the bolt connection is stable, easy to disassemble, and easy to maintain.

[0038] Optionally, the first drive assembly 22 includes a first motor 221 and a first coupling 222. The first motor 221 is mounted on the mounting bracket 21, and the first coupling 222 is connected to the output shaft of the first motor 221. The first coupling 222 can be connected to the cutter shaft 33. The cutter shaft 33 is driven by the first motor 221 to achieve automatic drive of the cutter shaft 33. The motor has high control precision and can provide continuous and stable power output to the cutter shaft 33, ensuring the stable operation of the cutter shaft 33. The connection method of the coupling is simple and clear, easy to disassemble and maintain, effectively improving the convenience of disassembly and assembly between the first drive assembly 22 and the cutter shaft 33, saving time and effort.

[0039] Of course, the second drive assembly 23 includes a second motor 231 and a second coupling 232. The second motor 231 is mounted on the mounting bracket 21, and the second coupling 232 is connected to the output shaft of the second motor 231. The second coupling 232 can be connected to the traction roller 32. The second motor 231 drives the traction roller 32 to achieve automatic drive of the traction roller 32. The motor has high control precision and can provide continuous and stable power output to the traction roller 32, ensuring the stable operation of the traction roller 32. The connection method of the coupling is simple and clear, easy to disassemble and maintain, effectively improving the convenience of disassembly and assembly between the second drive assembly 23 and the traction roller 32, saving time and effort.

[0040] Furthermore, the drive mechanism 2 also includes a first adjusting bracket 24 and a second adjusting bracket 25 that are vertically spaced on the mounting bracket 21. The first adjusting bracket 24 includes a first support portion 241 and a second support portion 242 arranged at an angle. The first drive assembly 22 is disposed on the first support portion 241. The second support portion 242 is provided with a second oblong hole 2421, the length of which extends vertically. The mounting bracket 21 is provided with a third threaded hole 212, through which a third bolt is screwed to the third threaded hole 212. The second support 242 is fixed to the mounting bracket 21 within the hole 212; the second adjusting bracket 25 includes a third support 251 and a fourth support 252 arranged at an angle, the second drive assembly 23 is disposed on the third support 251, the fourth support 252 is provided with a third oblong hole 2521, the length of the third oblong hole 2521 extends in the vertical direction, the mounting bracket 21 is provided with a fourth threaded hole 213, and the fourth bolt passes through the third oblong hole 2521 and is screwed into the fourth threaded hole 213 to fix the fourth support 252 to the mounting bracket 21. By setting the first adjusting bracket 24 and the second adjusting bracket 25, and by providing a second waist-shaped hole 2421 on the second support part 242 and a third waist-shaped hole 2521 on the fourth support part 252, the lengths of the second waist-shaped hole 2421 and the third waist-shaped hole 2521 both extend in the vertical direction, so that the first driving component 22 and the second driving component 23 can each have independent adjustment space in the vertical direction, ensuring the independence of the adjustment of the first driving component 22 and the second driving component 23 and the flexibility of installation.

[0041] Furthermore, the drive mechanism 2 also includes a third adjusting bracket 26 and a fourth adjusting bracket 27. The third adjusting bracket 26 includes a fifth support portion 261 and a sixth support portion 262 arranged at an angle. The first drive assembly 22 is disposed on the fifth support portion 261. The first support portion 261 is provided with a fourth oblong hole 2411, the length of which extends along a first direction. The sixth support portion 262 is provided with a fifth threaded hole 2621. A fifth bolt passes through the fourth oblong hole 2411 and is screwed into the fifth threaded hole 2621 to secure the first support portion 262. Part 241 is fixed to the sixth support part 262; the fourth adjusting bracket 27 includes a seventh support part 271 and an eighth support part 272 arranged at an angle, the second drive assembly 23 is disposed on the seventh support part 271, the third support part 251 is provided with a fifth oblong hole 2511, the length of the fifth oblong hole 2511 extends along the first direction, the eighth support part 272 is provided with a sixth threaded hole 2721, and the sixth bolt passes through the fifth oblong hole 2511 and is screwed into the sixth threaded hole 2721 to fix the third support part 251 and the eighth support part 272. By setting the third adjustment bracket 26 and the fourth adjustment bracket 27, and providing a fourth waist-shaped hole 2411 on the first support part 241 and a fifth waist-shaped hole 2511 on the third support part 251, the lengths of the fourth waist-shaped hole 2411 and the fifth waist-shaped hole 2511 both extend along the first direction, so as to further enhance the independent adjustment capability of the first drive assembly 22 and the second drive assembly 23 along the first direction, so as to realize that the first drive assembly 22 and the second drive assembly 23 can be adjusted along the first direction, the second direction and the third direction to adapt to the installation requirements, with a high degree of adjustment freedom.

[0042] For example, when adjustment is required, simply loosen the bolts, move the adjusting bracket along the length of the slotted hole to the designated position, and then tighten the bolts to secure it, making adjustment convenient.
