Description

Technical Field

[0001] The utility model relates to the technical field of bearing disassembly, in particular to a bearing disassembly and assembly device for a push rod connecting rod mechanism of a conveying drum wheel. Background Art

[0002] The GD X6 hard box packaging unit is a cigarette packaging unit designed and manufactured by the Italian GD company. It integrates mechanical, electrical, gas, liquid, optical and ultrasonic technology, and has a designed production capacity of 600 packs per minute. Domestic cigarette manufacturers began to introduce it in 2009, and it has now become the main production equipment of some large and medium-sized domestic cigarette factories. The entire production line of this unit is mainly composed of GDX6 small box packaging machine, C800 small box transparent paper packaging machine, BV strip box and strip box transparent paper packaging machine. The cigarette packs are formed by wrapping the quantitative cigarettes with lining paper, inner frame paper and trademark paper, and then the small box transparent paper is packaged, and then the strip box is packaged in two layers of five packs, and finally the required cigarette products are formed by strip box transparent paper packaging.

[0003] During the operation of the above-mentioned unit, the label paper conveying process is as follows: the suction rod mechanism of the first drum sucks the label paper from the paper storage one by one through the vacuum suction cup, and the sucked label paper is conveyed through the fixed guide rail above the first drum to the second drum for gluing. The glued label paper is conveyed to the third drum through the fixed guide rail, and after the code is pressed and the inner folding wing of the label box cover is folded, the label paper is conveyed to the transition area between the fourth drum and the fifth drum by the synchronous belt, and combined with the liner paper cigarette pack on the fourth drum, and finally sent to the fifth drum for label paper folding and packaging.

[0004] During the conveying process of trademark paper, all drums and synchronous belts are in continuous motion. To meet the intermittent motion requirements of the fourth and fifth drums, the push rod connecting rod mechanism used to push the trademark paper in the transition area is in intermittent motion. The push rod connecting rod mechanism is located below the conveying channel and the fifth drum, with a small movement space, high requirements on the execution accuracy of the push rod, and high speed. The bearings in this part are easily damaged during operation. In addition, due to the small space, the difficulty of disassembly and assembly during maintenance is greatly increased.

[0005] Existing patent applications have disclosed many bearing disassembly and assembly tools. For example, a utility model application with publication number CN218428138U discloses a bearing disassembly and assembly device for disassembling and assembling bearings on a carrier. The bearing disassembly and assembly device includes a supporting portion, an adjusting portion and a driving portion. The supporting portion is used to connect with the carrier to fix the carrier. The adjusting portion is respectively connected with the supporting portion and the driving portion to adjust the position of the driving portion so that the driving portion is aligned with the bearing on the carrier. The driving portion is connected with the bearing to drive the bearing to be separated from the carrier or assembled to the carrier.

[0006] However, due to the small size of the bearings and other parts of the push rod connecting rod mechanism of the fifth drum, high assembly requirements are placed on it, and the space available for disassembly and assembly is extremely narrow, the above-mentioned bearing disassembly and assembly device has an overly complex structure and occupies a large space, and cannot be applied to the disassembly and assembly environment of the bearings of the push rod connecting rod mechanism of the conveying drum. During disassembly and assembly, the use of such tooling for the operation will result in a significant reduction in the service life of the bearings if it is not done properly, and in severe cases, it will cause abnormal damage to the equipment.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] Part of the structure of the push rod connecting rod mechanism is as follows Figure 1 As shown, it includes a push rod 1 and at least one bearing 2. The push rod 1 is provided with a mounting hole 3 for mounting the bearing 2. The bearing 2 is provided with an axial hole 4. The mounting hole 3 and the axial hole 4 are located on a coaxial straight line.

[0030] In order to disassemble and assemble the bearing 2 on the push rod 1, this embodiment provides a bearing disassembly and assembly device for the push rod connecting rod mechanism of the conveying drum wheel, see Figure 1 and Figure 2The bearing disassembly and assembly device includes a disassembly and assembly rod 5 and a nut 6 threadedly connected to the disassembly and assembly rod 5, and the disassembly and assembly rod 5 passes through the mounting hole 3 and the shaft hole 4; the nut 6 is configured to rotate so that the disassembly and assembly rod 5 can move axially, specifically: one side of the nut 6 is directly abutted against the push rod 1 or indirectly through other components, and when the nut 6 is tightened toward the push rod 1, the nut 6 is abutted and stopped and cannot be displaced, and the disassembly and assembly rod 5 threadedly connected thereto will be exerted a force in the opposite direction by the threaded inclined surface, thereby causing axial displacement.

[0031] It also includes an abutment member 8, which abuts against the bearing 2 and is connected to the disassembly rod 5. In addition, in order to ensure that the disassembly rod 5 does not affect other parts of the push rod-connecting rod mechanism when installing or disassembling the bearing 2, it is preferred that the disassembly rod 5 and the shaft hole 4 are located on a coaxial straight line. When in use, the nut 6 is tightened with a wrench, the disassembly rod 5 is axially displaced, and the abutment member 8 connected to the disassembly rod 5 applies an axial thrust to the bearing 2 abutted thereto, forcing the bearing 2 to be pushed into the mounting hole 3 or pushed out of the mounting hole 3, thereby completing the disassembly of the bearing 2. Compared with conventional bearing disassembly devices, this device has the advantages of simple structure and small footprint, and can perform disassembly and assembly operations of the bearing 2 in a narrow space such as a push rod-connecting rod mechanism without damaging the equipment.

[0032] In some embodiments, a support member 7 is further included, and the support member 7 is disposed between the push rod 1 and the nut 6. As a further improvement of this embodiment, the support member 7 includes a top plate and a side plate; the top plate abuts against the nut 6 and is provided with a first through hole for the disassembly rod 5 to pass through, and the side plate abuts against the push rod 1. Such a structure can abut against and stop the nut 6 to prevent it from axially displacing along the push rod 1, while protecting the push rod 1.

[0033] In some embodiments, Figure 1 As shown, the nut 6 is located at the first end of the disassembly rod 5, and the first abutment member 81 is located at the second end of the disassembly rod 5. As a further improvement of this embodiment, the first abutment member 81 is an outer hexagonal. When in use, the outer hexagonal can be further clamped with a wrench while tightening the nut 6 to enhance its thrust on the bearing 2.

[0034] like Figure 1 As shown, the number of bearings 2 of the push rod connecting rod mechanism may be multiple, Figure 1 The two bearings 2 in the figure are respectively a first bearing 21 and a second bearing 22. It should be noted that: Figure 1The two bearings 2 shown are only applicable to this embodiment and are not limited to all push rod-connecting rod mechanisms. To ensure that the bearing disassembly and assembly device can disassemble and assemble all bearings 2, in some embodiments, the second abutment 82 is arranged between two adjacent bearings 2. When the outermost bearing 2 is pushed, the second abutment 82 can transmit the thrust and enable other bearings 2 to be installed or disassembled. As a further improvement of this embodiment, the second abutment 82 is detachably connected to the disassembly and assembly rod 5.

[0035] In some embodiments, a second through hole is provided in the middle of the abutment 8 for the disassembly rod 5 to pass through, and the inner diameter of the second through hole is smaller than the outer diameter of the bearing 2 to ensure that the bearing 2 does not slip out of the second through hole during disassembly.

[0036] In some embodiments, in order to make the disassembly rod 5 and the nut 6 fit more tightly and save more effort during use, the outside of the disassembly rod 5 is preferably provided with an anti-skid layer, which can be a surface-coated anti-skid material.

[0037] In some specific embodiments, the installation process of the bearing disassembly and assembly device on the bearing 2 is as follows:

[0038] like Figure 1 As shown, when the first bearing 21 and the second bearing 22 need to be installed, the disassembly rod 5 fixedly connected to the first abutment member 81 passes through the first bearing 21 and the second bearing 22 from right to left in sequence. Figure 1 The second bearing 22, the push rod 1, the second abutment 82, the first bearing 21, the hole set on the support member 7 are arranged in the direction shown, and finally the nut 6 is screwed on. After completing the above steps, use a wrench to clamp the first abutment 81 with an outer hexagonal shape, and tighten the nut 6 with another wrench. Due to the existence of the support member 7, the nut 6 will not move rightward along the axial direction of the disassembly rod 5. The disassembly rod 5 obtains a leftward force from the threaded inclined surface, driving the first abutment 81 to apply a leftward thrust to the second bearing 22 to push it into the installation hole 3. At the same time, the second bearing 22 will give the second abutment 82 a leftward thrust, prompting the second abutment 82 to push the first bearing 21 into another installation hole 3. When both bearings 2 are installed, remove the nut 6, and pass the disassembly rod 5 out to remove the entire bearing disassembly device.

[0039] In some specific embodiments, the disassembly process of the bearing 2 by the bearing disassembly and assembly device is as follows:

[0040] like Figure 2 As shown in the figure, when the first bearing 21 and the second bearing 22 need to be removed, the disassembly rod 5 fixedly connected to the first abutment member 81 passes through the first bearing 21 and the second bearing 22 from left to right in sequence. Figure 2The first bearing 21, the second abutment 82, the second bearing 22, the holes set on the support member 7 are arranged in the direction shown, and finally the nut 6 is screwed on. After completing the above steps, clamp the first abutment 81 with an external hexagonal shape with a wrench, and tighten the nut 6 with another wrench. Due to the existence of the support member 7, the nut 6 will not move to the left along the axial direction of the disassembly rod 5. The disassembly rod 5 obtains a rightward force from the threaded inclined surface, driving the first abutment 81 to apply a rightward thrust to the first bearing 21 to push it out of the mounting hole 3. At the same time, the first bearing 21 will give the second abutment 82 a rightward thrust, prompting the second abutment 82 to push the second bearing 22 out of the other mounting hole 3. When both bearings 2 are disassembled, remove the nut 6, and pass the disassembly rod 5 out to remove the entire bearing disassembly device.
