Description

Technical Field

[0001] The utility model relates to the technical field of cigarette bar conveying equipment, in particular to a quick replacement component for a cigarette bar conveying chain. Background Technique

[0002] The function of the cigarette bar conveying chain is to convey the cigarette packs produced by the packaging machine to the case packing machine for the next process of packaging. After long-term operation, the conveying chain will have problems such as tooth skipping, slipping, and breaking. Therefore, maintenance workers need to carry out preventive maintenance or emergency repair work on it. Since the conveying chain is installed in the air and has a long length, and each chain block is connected by a pin, the space is narrow, which brings great inconvenience to the maintenance workers for replacement.

[0003] During the maintenance process, the maintenance worker needs to disconnect and shorten the stretched conveying chain so that it will no longer skip teeth during operation, or cut off and reconnect the broken conveying chain. Therefore, during the process, the pin holes of two chain blocks need to be aligned and then the pin is inserted into the hole. Since the conveying chain is in a tensioned state after connection, it is very difficult to insert the pin manually and it is necessary to overcome the tensile force of the conveying chain. It is very difficult for a single maintenance worker to complete the operation independently and multiple people need to cooperate. Content of the Utility Model

[0027] The following will be combined with Figure 1 - Figure 2 Describe the quick-change component 10 of the cigarette conveying chain of the present utility model.

[0028] In view of the problems in the traditional technology that the maintenance of the cigarette conveying chain is not easy and the safety is relatively low, in order to solve the above problems, the present utility model provides a quick-change assembly 10 for a cigarette conveying chain, which is used for repairing and replacing the cigarette conveying chain. The quick-change assembly 10 for a cigarette conveying chain includes a positioning seat 1 and a quick-change tooling 2.

[0029] The positioning seat 1 has a first positioning portion 11 and a second positioning portion 12 arranged at intervals. The cigarette conveying chain 20 is arranged between the first positioning portion 11 and the second positioning portion 12. The first positioning portion 11 is used for clamping and fixing one side of the cigarette conveying chain 20; the quick-change tooling 2 includes a mounting seat 21, a quick-change shaft 22 and a driving portion 23 arranged on the mounting seat 21. The first positioning portion 11 is used for positioning the mounting seat 21. By providing the positioning seat 1, the cigarette conveying chain 20 and the quick-change tooling 2 can be effectively positioned, so that the quick-change shaft 22 of the quick-change tooling 2 is aligned with the shaft hole 21 of the cigarette conveying chain 20, and the pin can be accurately replaced or installed; the quick-change shaft 22 extends towards the shaft hole 21 of the cigarette conveying chain 20, and the driving portion 23 is used for driving the quick-change shaft 22 to expand and contract. When the quick-change shaft 22 expands and contracts, on the one hand, the pin can be ejected from the shaft hole 21 of the cigarette conveying chain 20 to complete the disassembly of the pin, and on the other hand, the pin can be driven into the shaft hole 21 of the cigarette conveying chain 20 to complete the installation of the pin. The quick-change assembly 10 for a cigarette conveying chain provided by the present utility model can significantly improve the replacement efficiency and safety of the pin shaft of the cigarette conveying chain 20.

[0030] As described above, the quick-change shaft 22 needs to perform telescopic movement. Specifically, a mounting hole is penetrated through the mounting seat 21, the quick-change shaft 22 is movably arranged in the mounting hole, and a transmission block 211 is arranged on the quick-change shaft 22. The driving portion 23 is used for driving the transmission block 211 towards the cigarette conveying chain 20 to drive the quick-change shaft 22 to expand and contract. The driving portion 23 has various implementation manners. Relatively simply, a linear driver, such as a pen-shaped cylinder, can be set. The telescopic movement of the cylinder drives the transmission block 211 to move and further drives the quick-change shaft 22 to expand and contract. However, on the one hand, the equipment cost is relatively high, and on the other hand, the pin needs to be knocked multiple times during the installation and disassembly of the pin, and it is inconvenient to use electric control. In the technical solution provided by the present utility model, a handle 212 is arranged at the lower end of the mounting seat 21, and the driving portion 23 includes a wrench 231. Please refer to Figure 1 - Figure 2, the wrench 231 is inclined and hinged to the handle 212, an included angle is formed between the wrench 231 and the handle 212, and the end of the wrench 231 abuts against the transmission block 211. During actual use, technicians can hold the handle 212 and the wrench 231 by hand. During the process of pressing the wrench 231, the wrench 231 will approach the handle 212, and the included angle between the two will decrease. In this way, the transmission block 211 can be driven to move, thereby driving the quick-change shaft 22 to expand and contract. Through the setting form of the handle 212 and the wrench 231, the pin can be impacted continuously for multiple times, and it is convenient for manual control, which can further reduce the cost on the basis of ensuring efficiency.

[0031] Furthermore, for the convenience of resetting, a return spring 213 is also sleeved on the quick-change shaft 22. One end of the return spring 213 abuts against the transmission block 211, and the other end abuts against the mounting seat 21. When an operator presses the wrench 231 by hand, the transmission block 211 will move, thereby compressing the return spring 213. When the force applied to the wrench 231 by the operator disappears, the elastic force of the return spring 213 will push the transmission block 211 back to its original position, thereby driving the wrench 231 back to its original position to prevent the equipment from jamming.

[0032] It should be noted that there are various ways to set the quick-change shaft 22 and the transmission block 211. A relatively simple way is that the transmission block 211 is directly set on the quick-change shaft 22, and there is no relative movement between the two. In this way, the movement of the quick-change shaft 22 can be driven by the transmission block 211, and the quick-change shaft 22 can also be reset together with the reset spring 213 and the transmission block 211. In other optional implementation manners, the transmission block 211 is sleeved on the quick-change shaft 22 obliquely. Due to the oblique setting of the transmission block 211, the edge of the through hole on the transmission block 211 rubs against the quick-change shaft 22, and the two are relatively fixed through the frictional force. When the transmission block 211 moves under the action of the wrench 231, the frictional force drives the quick-change shaft 22 to move. Correspondingly, the quick-change tooling 2 further includes a limiting plate 214, and the limiting plate 214 is obliquely hinged to one end of the mounting seat 21 away from the first positioning portion 11. It should be noted that the limiting plate 214 and the extending direction of the transmission block 211 are arranged in a V shape, and the quick-change shaft 22 movably passes through the limiting plate 214. When the quick-change shaft 22 is in the initial state, due to the oblique setting of the limiting plate 214, the limiting plate 214 rubs against and abuts against the quick-change shaft 22, playing a certain limiting role on the quick-change shaft 22. When the quick-change shaft 22 moves under the drive of the transmission block 211, the quick-change shaft 22 can overcome the frictional force between it and the limiting plate 214, and then produce a telescopic movement. When the transmission block 211 is reset under the elastic force of the reset spring 213, it drives the wrench 231 and the quick-change shaft 22 to reset. At this time, the limiting plate 214 can continue to limit the quick-change shaft 22 to prevent the quick-change shaft 22 from detaching or having too large a displacement. When it is necessary to disassemble the quick-change shaft 22, the limiting plate 214 can be pressed to make the limiting plate 214 close to the mounting seat 21. In this way, the limiting plate 214 and the quick-change shaft 22 form a movably sleeved relationship, and the quick-change shaft 22 can be easily disassembled.

[0033] Further, on the one hand, in order to reset the limiting plate 214, and on the other hand, for shock absorption, a connecting spring 215 is also provided between the limiting plate 214 and the mounting seat 21. One end of the connecting spring 215 is connected to the limiting plate 214, and the other end is connected to one end face of the mounting seat 21 away from the first positioning portion 11. In order to facilitate observing the movement between the transmission plate and the wrench 231, a through groove 216 is opened in the mounting seat 21. The through groove 216 is communicated with the mounting hole. The transmission block 211 is arranged in the through groove 216, and the quick-change shaft 22 also passes through the through groove 216.

[0034] Further, the first positioning portion 11 includes an annular seat. The end of the mounting seat 21 is cylindrical, and the mounting seat 21 is sleeved and positioned on the annular seat. Correspondingly, the second positioning portion 12 includes a Y-shaped seat body and two positioning columns spaced on the Y-shaped seat body. The two positioning columns can clamp the convex block 22 on the side of the cigarette conveying chain 20 to position the cigarette conveying chain 20. It should be noted that the drawings are only for schematic illustration, and in actual use, the two positioning columns are clamped and connected with the convex block 22.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
