Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a sound insulation and noise reduction device for a ZB45 packaging machine. Background Technology

[0002] The ZB45 packaging machine is a type of cigarette hard box / carton packaging equipment. It can complete the entire production process from cigarette feeding to finished carton packaging at high speed and stably. The unit consists of a YB15 unloading machine, a YB45 hard box packaging machine, a YB55A box outer transparent paper packaging machine, a YB65A hard carton packaging machine, and a YB95 carton outer transparent paper packaging machine, which can effectively avoid manual contact with cigarettes.

[0003] During operation, the ZB45 packaging machine can complete the packaging and conveying of cigarette packs at a rate of 400 packs per minute. The No. 1 wheel needs to rotate 180° from a standstill to a standstill, then return to a standstill, and then rotate 180° again, repeating this intermittent motion 400 times per minute. This results in relatively high noise levels, which can harm the health of operators and poses a significant challenge to occupational health and safety management in factories. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sound insulation and noise reduction device for ZB45 packaging machines. This device can reduce noise at workstations that generate noise during the operation of the ZB45 packaging machine, thereby reducing noise transmission and preventing harm to operators. It also enables quick assembly and disassembly, saving time and effort.

[0005] According to an embodiment of this utility model, a sound insulation and noise reduction device for a ZB45 packaging machine includes: at least two interconnected cover plates, each cover plate having a sandwich design, and each cover plate having a cavity and a sound-absorbing cotton sandwich layer sequentially inside; a connecting assembly, wherein multiple connecting assemblies are arranged between any two interconnected cover plates, each connecting assembly including a rod and a locking groove, the rod and locking groove being respectively arranged on the two interconnected cover plates; an abutting block, movably installed in the locking groove along a direction perpendicular to the movement of the rod, the rod having a corresponding auxiliary fixing groove, a driving assembly being arranged between the abutting block and the auxiliary fixing groove, the abutting block being engaged with the auxiliary fixing groove through the driving assembly; and a reset assembly, wherein multiple reset assemblies are connected to the abutting blocks respectively, the reset assemblies being used to quickly separate the abutting blocks and the auxiliary fixing grooves.

[0006] The technical principle of this utility model is as follows: The operator aligns the insert rod and the locking groove on the two cover plates respectively, and pushes the insert rod to slide into the locking groove. At this time, under the action of the drive component, the inward sliding of the insert rod can drive the abutment block to move synchronously and engage with the corresponding auxiliary fixing groove. Under the dual action of the insert rod and locking groove, and the abutment block and auxiliary fixing groove, the two cover plates can be quickly connected. Subsequently, one of the cover plates can be connected to the machine shell that needs noise reduction using bolts or other structures. The noise emitted by the machine during operation will pass through the sound-absorbing cotton interlayer and the cavity in sequence, achieving a two-stage noise reduction effect, preventing noise leakage and preventing harm to the operator's health. The reset component can also quickly separate the abutment block and the auxiliary fixing groove, and then separate the insert rod and the locking groove, so that the two cover plates can be separated and reset.

[0007] Furthermore, the drive assembly includes a drive gear and a first double-sided rack. The drive gear is rotatably mounted on the insert rod, and the first double-sided rack is slidably disposed inside the snap-fit ​​groove along the moving direction of the insert rod. The first double-sided rack is engaged with the drive gear, and the abutment block is connected to the first double-sided rack through the drive assembly.

[0008] By adopting the above technical solution, while the insertion rod slides into the locking groove, it can drive the abutment block to move synchronously through the drive gear and the first double-sided rack and pinion.

[0009] Furthermore, the driving assembly includes a driven gear, a second double-sided rack, and a wedge block. The driven gear is rotatably mounted on the inner wall of the snap-fit ​​groove. The second double-sided rack is movably disposed inside the snap-fit ​​groove along the moving direction of the insert rod. The first and second double-sided racks are symmetrically arranged about the center of the driven gear as an axis of symmetry. Both the first and second double-sided racks are engaged with the driven gear. The wedge block is slidably disposed inside the snap-fit ​​groove along the moving direction of the abutment block. The wedge block is fixedly connected to the abutment block. The end of the second double-sided rack away from the driven gear abuts against the inclined end face of the wedge block. The reset assembly is connected to the wedge block.

[0010] By adopting the above technical solution, when the second double-sided rack is driven to move, it can abut against the inclined end face of the wedge block to drive the wedge block to slide, thereby driving the abutment block to move towards the auxiliary fixing groove to achieve snap-fit ​​fixing.

[0011] Furthermore, the reset assembly includes a telescopic rod, a pull rod, and an elastic element. The side wall of the snap-fit ​​groove is provided with a through hole communicating with the outside. One end of the telescopic rod is fixedly connected to the wedge block, and the other end extends outward through the through hole and is fixedly connected to the pull rod. The pull rod abuts against the outer surface of the cover plate. The elastic element is installed between the telescopic rod and the wedge block.

[0012] By adopting the above technical solution, when it is necessary to disassemble the two cover plates, the operator only needs to pull the pull rod outward. The pull rod drives the telescopic rod to shorten, thereby compressing the elastic element, so that the abutment block can be separated from the auxiliary fixing groove, and it is also convenient for the insertion rod and the snap-fit ​​groove to disengage.

[0013] Furthermore, each of the snap-fit ​​slots has abutment blocks movably provided on its opposite side walls, and each insert has auxiliary fixing slots on its opposite sides.

[0014] By adopting the above technical solution, abutment blocks and auxiliary fixing grooves are set on both sides of the plug rod, which can enhance the connection stability of the two cover plates.

[0015] Furthermore, the overlapping outer edges of the two interconnected cover plates are covered with a rubber membrane.

[0016] By adopting the above technical solution, the rubber membrane can further enhance the connection stability between the cover plates and also further reduce noise.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a cavity and sound-absorbing cotton interlayer, when the machine makes noise during operation, the noise gradually weakens as it passes through the sound-absorbing cotton interlayer and the cavity, greatly reducing the volume of leaked noise and preventing harm to the operator.

[0019] 2. By setting up insert rods, snap-fit ​​slots, abutment blocks, auxiliary fixing slots and drive components, the interconnected cover plates have a dual connection effect, which improves the connection stability between the cover plates and can be effectively applied to actual production operation scenarios. Furthermore, the reset component can achieve quick disassembly of the cover plates, saving time and effort. Attached Figure Description

[0029] like Figure 1-5 As shown in the figure, this utility model embodiment proposes a sound insulation and noise reduction device for a ZB45 packaging machine, comprising: at least two interconnected cover plates 1, each cover plate 1 having a sandwich design, with a cavity 2 and a sound-absorbing cotton sandwich layer 3 sequentially arranged inside; a connecting assembly, having multiple sets and disposed between any two interconnected cover plates 1, the connecting assembly including an insert rod 4 and a snap-fit ​​groove 5, the insert rod 4 and the snap-fit ​​groove 5 being respectively disposed on the two interconnected cover plates 1; an abutment block 8, movably installed in the snap-fit ​​groove 5 in a direction perpendicular to the movement of the insert rod 4, the insert rod 4 having a corresponding auxiliary fixing groove 9, the abutment block 8 being snapped into the auxiliary fixing groove 9 through a driving assembly; and a reset assembly, having multiple sets and connected to multiple abutment blocks 8 respectively, for quickly separating the abutment block 8 and the auxiliary fixing groove 9.

[0030] Furthermore, the drive assembly includes a drive gear 6 and a first double-sided rack 7. The drive gear 6 is rotatably mounted on the insert rod 4, and the first double-sided rack 7 is slidably disposed inside the snap-fit ​​groove 5 along the moving direction of the insert rod 4. The first double-sided rack 7 is engaged with the drive gear 6 in a transmission manner, and the abutment block 8 is connected to the first double-sided rack 7 through the drive assembly.

[0031] Furthermore, the drive assembly includes a driven gear 11, a second double-sided rack 10, and a wedge block 12. The driven gear 11 is rotatably mounted on the inner wall of the snap-fit ​​groove 5. The second double-sided rack 10 is also movably disposed inside the snap-fit ​​groove 5 along the moving direction of the insert rod 4. The first double-sided rack 7 and the second double-sided rack 10 are symmetrically arranged with the center of the driven gear 11 as the axis of symmetry. Both the first double-sided rack 7 and the second double-sided rack 10 are engaged with the driven gear 11. The wedge block 12 is slidably disposed inside the snap-fit ​​groove 5 along the moving direction of the abutment block 8, and the wedge block 12 is fixedly connected to the abutment block 8. The end of the second double-sided rack 10 away from the driven gear 11 abuts against the inclined end face of the wedge block 12. The reset assembly is connected to the wedge block 12.

[0032] Furthermore, the reset assembly includes a telescopic rod 13, a pull rod 15, and an elastic element 14. The side wall of the snap-fit ​​groove 5 is provided with a through hole communicating with the outside. One end of the telescopic rod 13 is fixedly connected to the wedge block 12, and the other end extends outward through the through hole and is fixedly connected to the pull rod 15. The pull rod 15 abuts against the outer surface of the cover plate 1. The elastic element 14 is installed between the telescopic rod 13 and the wedge block 12.

[0033] Furthermore, each snap-fit ​​groove 5 has abutment blocks 8 movably provided on its opposite side walls, and correspondingly, each insert rod 4 has auxiliary fixing grooves 9 on its opposite sides.

[0034] Furthermore, the overlapping outer edges of the two interconnected cover plates 1 are covered with a rubber membrane (not shown in the figure).

[0035] The implementation principle of this application embodiment is as follows: The operator aligns the insert rod 4 and the snap-fit ​​groove 5 on the two cover plates 1 with each other, and then pushes the insert rod 4 inward. While the insert rod 4 moves, the drive gears 6 on its left and right sides drive the first double-sided rack 7 to slide into the depth of the snap-fit ​​groove 5. The first double-sided rack 7 moves, thereby driving the driven gear 11 to rotate. The second double-sided rack 10, which meshes with the driven gear 11 on the other side, is driven to slide away from the snap-fit ​​groove 5. While the second double-sided rack 10 slides, its top end keeps abutting against the wedge block 12, and continuously pushes the abutting block 8 along the inclined end face of the wedge block 12, so that the two abutting blocks 8 located in the same snap-fit ​​groove 5 move closer to each other until they abut against the insert rod 4 and connect with the corresponding auxiliary fixing groove 9 on the insert rod 4, so that the two cover plates 1 can be quickly installed.

[0036] Operators can choose to connect one cover plate 1 to the machine casing that needs noise reduction using bolts or other structures, and then install the other cover plate 1. Alternatively, they can assemble the two cover plates 1 together and then install them with the machine. After the cover plate 1 is installed with the machine, the machine will generate a lot of noise due to continuous high-speed operation. As the noise is transmitted out of the cover plate 1, it will gradually weaken as it passes through the sound-absorbing cotton interlayer 3 and the cavity 2. By the time it reaches the outside, the volume has been greatly reduced, which also avoids harm to the health of the operators and provides good noise reduction and sound insulation.

[0037] When it is necessary to disassemble the two connected cover plates 1, the operator only needs to pull the pull rod 15 outward. The pull rod 15 causes the overall length of the telescopic rod 13 to shorten, thereby compressing the elastic element 14, causing the wedge blocks 12 to move away from each other and disengage from the auxiliary fixing groove 9. At this time, the inclined end face of the wedge block 12 can push the second double-sided rack 10 to slide deeper into the snap-fit ​​groove 5, thereby causing the driven gear 11 to rotate in the opposite direction, causing the first double-sided rack 7 to slide in the opposite direction, pushing the insert rod 4 outward from the snap-fit ​​groove 5, which facilitates the quick separation of the two cover plates 1 and achieves quick disassembly.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
