Description

Technical Field

[0001] This utility model belongs to the field of cigarette manufacturing technology, specifically relating to a cigarette chain adjustment tool for a cigarette packaging machine. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Existing cigarette packaging machines use double-row chains with lug pushers to convey cigarettes and aluminum packs. For example, the ZB48 packaging machine adopts a dual-track packaging design with two cigarette chains. Each chain has 14 lug assemblies. According to maintenance requirements, the cigarette chains need adjustment and replacement every 3500 hours of operation. The crossbeam and side plates of the lug assembly have a 1mm horizontal adjustment range, with an overall adjustment range of 235±1mm. The position of the cigarette conveying chain is adjusted by changing the length of the lug assembly. According to the technical manual, the positioning length of the lug assembly should ideally be 235+(0.2~0.3)mm.

[0004] The prior art discloses a special tool for adjusting the width of chain components in a cigarette packaging machine, which includes a module with a groove on the module. The groove has two trapezoidal sides. The lug components are first placed into the groove and assembled, and then connected to the left and right chains to ensure that all lug components on the double-row chains have the same width.

[0005] However, the lug assembly includes a fixed-length crossbeam, with the left and right side plates connected to both ends. The left and right side plates are threadedly connected to the cigarette chains on both sides. Therefore, the outer surface of the two side plates of the lug assembly has a boss at its center, and the boss has threads. The above solution has the following drawbacks in practical applications: Since the lug assembly is generally connected to the chain by threads at both ends, when the lug assembly is placed into the module of the above scheme, the horizontal movement of the lug assembly's fixed-length crossbeam can only be limited. When adjusting the length between the left and right side plates of the lug assembly, the lug assembly is prone to longitudinal displacement. When the lug assembly is longitudinally displaced, the bosses on both sides of the lug assembly will not be able to fit tightly with the module groove, resulting in the left and right side plate spacing of all lug assemblies not being completely consistent after adjustment. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a cigarette chain adjustment tool for a cigarette packaging machine, which can solve the technical problem in the prior art that the lug assembly is prone to longitudinal displacement in the module groove, resulting in the left and right side plate spacing of all lug assemblies not being completely consistent after adjustment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A cigarette chain adjustment tool for a cigarette packaging machine includes a fixed-length rod with a groove on the rod, stepped slots at both ends of the groove, a lug assembly placed in the groove, and two threaded holes machined on each side of the fixed-length rod. It also includes an eccentric disk with a through hole. The center line of the through hole is parallel to the center line of the eccentric disk but not on the same axis. After the through hole is aligned with the first threaded hole, the internal hex screw passes through the through hole and the first threaded hole in sequence and is threadedly connected to the first threaded hole.

[0008] Preferably, the lug assembly includes a fixed-length crossbeam, with a left side plate and a right side plate connected to both ends of the fixed-length crossbeam, and a boss connected to the outer side of the left side plate and the right side plate, the width of which is equal to the width of the fixed-length rod.

[0009] Preferably, the length of the fixed-length crossbeam is equal to the distance between the stepped grooves at both ends of the groove, and the width of the fixed-length crossbeam is equal to the width of the groove.

[0010] Preferably, the left and right side plates are symmetrical about the center line of the long side of the fixed-length crossbeam.

[0011] Preferably, a boss is fixedly connected to the center of the outer side of the vertical plate of both the left and right side plates, and a second threaded hole is opened on the boss, which passes through the boss and the vertical plate.

[0012] Preferably, both the left and right side panels are L-shaped panels, including horizontal and vertical panels that are perpendicular to each other, and the horizontal and vertical panels are fixedly connected.

[0013] Preferably, adjustment holes are provided on the horizontal plates of both the left and right sides, and third threaded holes are provided at both ends of the fixed-length crossbeam.

[0014] Preferably, after the adjusting hole and the third threaded hole are aligned, the fixing screw passes through the adjusting hole and is threadedly connected to the third threaded hole.

[0015] Preferably, the length of the adjusting hole is greater than the diameter of the third threaded hole, and the width of the adjusting hole is equal to the diameter of the third threaded hole.

[0016] Preferably, after the adjusting hole is aligned with the third threaded hole, the center of the adjusting hole and the third threaded hole is located on the center line of the short side of the fixed-length crossbeam.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are: This invention connects multiple eccentric discs to both sides of a fixed-length rod. When the hex socket screws are loosened while remaining connected to the fixed-length rod, the eccentric discs can rotate eccentrically around the hex socket screws through the through holes. The eccentric discs block the grooves on both sides. After tightening the hex socket screws, the longitudinal direction of the lug assembly is limited. The lug assembly cannot move longitudinally, ensuring that the boss and groove are tightly fitted, thus making the spacing between the left and right side plates of all lug assemblies completely consistent after adjustment.

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a cigarette packing machine cigarette chain adjustment tool, such as... Figure 1 , Figure 2 , Figure 4 As shown, the device includes a fixed-length rod 3. A groove 31 is formed on the fixed-length rod 3 along its length. The length of the groove 31 is less than the length of the fixed-length rod 3, and the center line of the long side of the groove 31 is the same as the center line of the long side of the fixed-length rod 3. The two sides of the groove 31 extend through both sides of the fixed-length rod 3. Figure 1 , Figure 2 , Figure 4 As shown, stepped slots 32 are formed at both ends of the groove 31. The stepped slots 32 are in the form of two steps, as shown in the figure. Figure 8 As shown, the lug assembly 9 is placed in the groove 31 for length adjustment, and the groove 31 provides lateral limitation for the lug assembly 9.

[0022] like Figure 2 , Figure 4 As shown, multiple eccentric disks 2 are connected to both sides of the fixed-length rod 3. Specifically, multiple first threaded holes 33 of corresponding positions and sizes are machined on both sides of the fixed-length rod 3, as shown in the figure. Figure 3 As shown, a through hole 21 is opened on the eccentric disk 2. The center line of the through hole 21 is parallel to the center line of the eccentric disk 2 but not on the same axis. After the through hole 21 is aligned with the first threaded hole 33, the internal hex screw 1 passes through the through hole 21 and the first threaded hole 33 in sequence and is threadedly connected to the first threaded hole 33.

[0023] In this embodiment, two eccentric disks 2 are connected to each side of the fixed-length rod 3.

[0024] It should be noted that, since the eccentric disk 2 has a through hole 21, when the hex socket screw 1 is loosened but still connected to the length-fixing rod 3, the eccentric disk 2 can rotate eccentrically around the hex socket screw 1 through the through hole 21. It should also be noted that, in this embodiment, the diameter of the eccentric disk 2 is larger than the height of the length-fixing rod 3. Figure 8 As shown, when the lug assembly 9 is placed in the groove 31 for length adjustment, the eccentric disc 2 rotates eccentrically upward through the through hole 21 around the internal hex screw 1. The eccentric disc 2 can block on both sides of the groove 31. Then, the internal hex screw 1 is tightened to limit the longitudinal movement of the lug assembly 9.

[0025] It is understood that in this embodiment, by connecting two eccentric disks 2 on each side of the fixed-length rod 3, the lug assembly 9 can be longitudinally limited to prevent longitudinal displacement of the lug assembly 9 and ensure that the bosses on both sides of the lug assembly are in close contact with the module groove.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 5 As shown, the diameter of the head cap of the internal hex screw 1 is larger than the diameter of the through hole 21 and the first threaded hole 33, ensuring that when the internal hex screw 1 is tightened, the head cap of the internal hex screw 1 will squeeze the eccentric disc 2 tightly against the side of the fixed length rod 3.

[0027] In this embodiment, as Figure 6 , Figure 7 As shown, the lug assembly 9 includes a fixed-length crossbeam 5, with the left side plate 4 and the right side plate 6 respectively connected to its two end surfaces; as Figure 11 As shown, the left cigarette chain 8 is connected to the left side plate 4, and the right cigarette chain 8 is connected to the right side plate 6. The lug assembly 9 is connected and supported between the two cigarette chains 8. All lug assemblies 9 have the same length, which can ensure that the spacing between the two cigarette chains 8 is constant, ensure the accuracy of the cigarette chain assembly on the machine, and improve the operating efficiency of the equipment.

[0028] In this embodiment, as Figure 8 As shown, the width of the boss 41 is equal to the width of the fixed-length rod 3. After the horizontal and vertical directions of the fixed-length beam 5 are limited by the groove 31 and the eccentric disk 2 respectively, the two sides of the boss 41 are aligned with the two sides of the fixed-length rod 3 to ensure the alignment of the left side plate 4 and the right side plate 6. However, the module in the background technology, due to the lack of a longitudinal limiting measure, cannot ensure that the fixed-length beam 5 coincides with the short side centerline of the module, and therefore cannot ensure that the boss 41 coincides with the short side centerline of the module, and cannot guarantee that the boss is tightly attached to the module.

[0029] like Figure 8 , Figure 9 , Figure 10 As shown, the length of the fixed-length beam 5 is equal to the distance between the stepped slots 32 at both ends of the groove 31. The lug assembly 9 is placed in the fixed-length rod 3, and the fixed-length beam 5 is engaged within the groove 31, thereby allowing the stepped slots 32 of the groove 31 to laterally limit the two ends of the fixed-length beam 5. Figure 8 , Figure 9 , Figure 10 As shown, the width of the fixed-length crossbeam 5 is equal to the width of the groove 31 (that is, equal to the width of the fixed-length rod 3). Rotate the eccentric disk 2 to longitudinally limit the two sides of the fixed-length crossbeam 5.

[0030] It is understandable that limiting the horizontal and vertical directions of the fixed-length beam 5 can ensure that the fixed-length beam 5 will not be displaced.

[0031] like Figure 6 , Figure 7 As shown, in this embodiment, the left side plate 4 and the right side plate 6 have the same shape and size, and are symmetrical about the center line of the long side of the fixed-length crossbeam 5.

[0032] like Figure 6 , Figure 7 As shown, the outer center of the vertical surfaces of the left side plate 4 and the right side plate 6 are fixedly connected (this fixed connection can be achieved by integral manufacturing) to a boss 41. A second threaded hole is formed on the boss 41, penetrating through the boss 41 and the vertical plate. It is not difficult to understand that, as... Figure 11 As shown, the protrusions 41 of the left side plate 4 and the right side plate 6 are respectively connected to the cigarette chain 8 on the left side and the cigarette chain 8 on the right side by locking bolts.

[0033] It should be noted that the centerline of the boss 41 passes through the center of the adjustment hole 42, and the centerline of the boss 41 coincides with the centerline of the short side of the fixed-length crossbeam 5 and also with the centerline of the short side of the fixed-length rod 3.

[0034] In this embodiment, as Figure 6 , Figure 7 As shown, both the left side plate 4 and the right side plate 6 are L-shaped plates, including mutually perpendicular horizontal and vertical plates, which are fixedly connected. The horizontal plates are parallel to the fixed-length beam 5 and are attached to the surface of the fixed-length beam 5. The vertical plates are used to connect with the cigarette chain 8.

[0035] In this embodiment, the horizontal and vertical plates are made of the same material and can be fixedly connected by being manufactured as a single piece.

[0036] like Figure 9 , Figure 10 As shown, adjustment holes 42 are provided on the horizontal plates of the left side plate 4 and the right side plate 6. Third threaded holes 51 are provided at both ends of the fixed length beam 5. The horizontal plates of the left side plate 4 and the right side plate 6 are placed at both ends of the fixed length beam 5 respectively. After the adjustment holes 42 and the third threaded holes 51 are aligned, the fixing screws 7 are passed through the adjustment holes 42 and the third threaded holes 51, so that the fixing screws 7 are threadedly connected to the third threaded holes 51, and the left side plate 4 and the right side plate 6 are connected to the fixed length beam 5.

[0037] It is understandable that the diameter of the head cap of the fixing screw 7 is larger than the size of the adjustment hole 42 and also larger than the size of the third threaded hole 51. When the fixing screw 7 is tightened, the left side plate 4 and the right side plate 6 can be fixed to both ends of the fixed length crossbeam 5.

[0038] It should be noted that, in this embodiment, the adjustment hole 42 is a smooth hole.

[0039] It should also be noted that, such as Figure 9 As shown, in this embodiment, the length of the adjusting hole 42 is greater than the diameter of the third threaded hole 51, and the width of the adjusting hole is equal to the diameter of the third threaded hole. When adjusting the length between the left side plate 4 and the right side plate 6, the adjusting hole 42 and the third threaded hole 51 will not be misaligned, and the fixing screw 7 will not be unable to be inserted into the adjusting hole 42 and the third threaded hole 51. This ensures the connection between the left side plate 4 and the right side plate 6 on the fixed-length crossbeam 5, and also ensures the adjustment of the distance between the left side plate 4 and the right side plate 6 on the fixed-length crossbeam 5.

[0040] It should also be noted that after the adjusting hole 42 is aligned with the third threaded hole 51, the center of the adjusting hole 42 and the third threaded hole 51 is located on the short side centerline of the fixed-length crossbeam 5.

[0041] Instructions for use: In use, place the lug assembly 9 on the length-fixing rod 3 and put the length-fixing crossbeam 5 into the groove 31 to achieve lateral limitation of the lug assembly 9, so that the length-fixing crossbeam 5 and the length-fixing rod 3 are aligned on both sides. Then rotate the eccentric discs 2 on both sides of the length-fixing rod 3 to block the length-fixing crossbeam 5 on both sides. Tighten the hex socket screws 1 to achieve longitudinal limitation of the lug assembly 9, ensuring that the lug assembly 9 will not wobble when adjusting the length. Loosen the fixing screws 7 at both ends of the lug assembly 9, so that the left side plate 4 and the right side plate 6 move horizontally toward both ends, so that the bosses 41 of the two side plates are close to the side of the stepped groove 32, and the two sides of the bosses 41 are aligned with the two sides of the length rod 3. Then tighten the fixing screws 7 at both ends of the lug assembly 9 to complete the length adjustment of the lug assembly 9.

[0042] In this embodiment, adjusting the length of the lug assembly 9 will not cause longitudinal displacement of the lug assembly 9, thus avoiding rework in one go, reducing maintenance difficulty, improving maintenance efficiency, and improving the consistency of the adjustment of the cigarette chain lug assembly, ensuring the accuracy of the cigarette chain assembly on the machine, and improving the operating efficiency of the equipment. Furthermore, the cigarette chain adjustment tool of the cigarette packaging machine in this embodiment has a simple structure, is easy to manufacture and install, and does not require the use of other measuring tools when adjusting the length of the lug assembly 9, making the adjustment convenient, accurate, and quick.

[0043] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
