Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging equipment, in particular to a cigarette conveying device. Background Art

[0002] The YB518 small-box transparent paper packaging machine currently used by cigarette factories uses an integrated connection method between the small-box conveyor belt and the lugs, or the lugs are directly bonded to the conveyor belt. Because the lugs are fixedly connected between the conveyor teeth of the conveyor belt, the stress on the conveyor belt and the lugs is relatively concentrated during operation, and the lugs are prone to breakage or falling after being loaded. At the same time, when irregular cigarette packs such as rotten or damaged packs pass through the YB518 small-box transparent paper packaging machine, cigarettes are easily clamped in the machine, causing the equipment to shut down. When the cigarettes are clamped in the lugs of the conveyor belt, the lugs will break or fall. The lugs are difficult to repair, so the entire conveyor belt must be replaced, resulting in increased repair costs after the lugs break or fall. Moreover, replacing the conveyor belt is cumbersome and time-consuming, resulting in excessive downtime of production equipment, thereby reducing production efficiency and increasing production costs. If the conveyor belt breaks slightly but doesn't fall, the lugs can become skewed. While cigarette packs can still pass through, they can be misplaced, causing them to collide with the conveyor channel, resulting in wrinkles or even damage, leading to quality issues. In severe cases, if substandard products aren't discovered promptly, by the time they're spotted during spot checks, a significant number of them have already been sent to the next process, increasing the number of defective products.

[0014] As a further technical solution, the mounting assembly includes a slide rail, a slide groove and an elastic member;

[0015] The slide rail is arranged on one of the connecting portion and the lug body, and the slide groove is arranged on the other. The slide groove extends along the X direction.

The entire cigarette conveying device can be put into production and use again without replacing the entire cigarette conveying device. Therefore, maintenance is convenient and time-consuming, thereby reducing maintenance costs and production costs and improving production efficiency. In addition, since the lug body is detachably connected between two adjacent conveying teeth, when the conveyor belt is slightly broken, the connecting component at the corresponding position will become loose and the corresponding lug body will fall off. In this state, the transportation of cigarette packs can be stopped, and the operator can immediately repair the cigarette conveying device, thereby avoiding the situation where the product is unqualified due to inadequate delivery, and preventing unqualified products from entering the next process, thereby improving the product yield.

[0036] Specific combination Figures 1 to 6As shown, the cigarette conveying device provided in this embodiment can reduce maintenance and production costs, improve production efficiency, and increase product yield when conveying cigarette packs. Specifically, the cigarette conveying device includes a conveyor belt 100 and a lug mechanism 200. A plurality of conveying teeth 110 are provided on one side of the conveyor belt 100, and the plurality of conveying teeth 110 are evenly spaced along the length of the conveyor belt 100. The lug mechanism 200 includes a lug body 210 and a connecting assembly 220. The lug body 210 is detachably connected between two adjacent conveying teeth 110 via the connecting assembly 220.

[0037] Since the lug body 210 is detachably connected between two adjacent conveying teeth 110 through the connecting assembly 220, when the cigarette conveying device is working, if the lug body 210 breaks or falls due to stress concentration at the lug mechanism 200, or if the device clamps cigarettes due to the passage of irregular cigarette packs such as bad packs, and the cigarette clamping occurs at the lug mechanism 200, causing the lug body 210 to break or fall, it is only necessary to remove the corresponding connecting assembly 220 from between the two adjacent conveying teeth 110 to remove the damaged lug body 210 from the conveying mechanism, and then reconnect the new lug body 210 between the corresponding two conveying teeth 110 on the conveyor belt 100 through the connecting assembly 220, and the entire cigarette conveying device can be put into production and use again without replacing the entire cigarette conveying device. Therefore, maintenance is convenient and time-saving, thereby reducing maintenance costs and production costs and improving production efficiency. In addition, since the lug body 210 is detachably connected between two adjacent conveying teeth 110, when the conveyor belt 100 is slightly broken, the connecting component 220 at the corresponding position will become loose and the corresponding lug body 210 will fall off. In this state, the transportation of cigarette packs can be stopped, and the operator can immediately repair the cigarette conveying device, thereby avoiding the situation where the product is unqualified due to inadequate transportation, and preventing unqualified products from entering the next process, thereby improving the product yield.

[0038] At the same time, since the lug body 210 is detachably connected between two adjacent conveying teeth 110 through the connecting assembly 220, when installing the lug body 210, only the connecting assembly 220 is needed without modifying the conveyor belt 100, thereby further reducing production costs.

[0039] In addition, in this embodiment, the cigarette conveying device also includes at least two transmission gears 300, the two transmission gears 300 are arranged at intervals, the conveyor belt 100 is arranged in a ring shape connected end to end, and a plurality of conveying teeth 110 are arranged on the inner side of the ring conveyor belt 100. The two transmission gears 300 are both engaged with the conveying teeth 110 on the inner side of the conveyor belt 100, and the two transmission gears 300 are respectively connected to the output shaft of the external production equipment to drive the conveyor belt 100 to move, thereby realizing the conveyance of cigarette packs.

[0040] The embodiment provides three implementations of the lug body 210 being detachably connected between two adjacent conveying teeth 110 via the connecting assembly 220, as follows:

[0041] Implementation Method 1

[0042] Preferably, the connecting assembly 220 includes a pin shaft 221 and two bearing plates 222. The two bearing plates 222 are arranged at relative intervals on the lug body 210 along the X direction, and both bearing plates 222 are provided with connecting holes 2221. The middle part of the pin shaft 221 is clamped between two adjacent conveying teeth 110, and the two ends are respectively inserted into the two connecting holes 2221.

[0043] Two bearing plates 222 are spaced relative to each other along the X-direction on the lug body 210, forming a snap-fitting space with the lug body 210. When installing the lug body 210, the snap-fitting space is first snapped into place at the target location on the conveyor belt 100. The pin 221 then passes through the two connection holes 2221 in sequence. In this state, the middle portion of the pin 221 snaps into place between two adjacent conveyor teeth 110 within the target location. When the lug body 210 needs to be replaced, the pin 221 is simply removed. This process is simple, requiring only the lug body 210 to be replaced without requiring modification to the conveyor belt 100. Furthermore, in this embodiment, the distance between the two bearing plates 222 is equal to the width of the conveyor belt 100. When the lug body 210 is connected to the conveyor belt 100, the two bearing plates 222 abut against the two sidewalls of the conveyor belt 100, respectively, to enhance the strength and stability of the connection between the lug body 210 and the conveyor belt 100. The distance between the pin shaft 221 and the lug body 210 is less than the maximum thickness of the conveyor belt 100 to ensure that when the pin shaft 221 is inserted into the two connecting holes 2221, the middle part can be clamped between two adjacent conveying teeth 110 to limit the relative position of the lug body 210 and the conveyor belt 100 in the length direction of the conveyor belt 100.

[0044] In order to further enhance the inherent strength of the lug mechanism 200 and thereby enhance the connection strength and stability when the lug body 210 is connected to the conveyor belt 100 to achieve the technical effect of extending the service life, in this embodiment, the two bearing plates 222 are integrally formed with the lug body 210.

[0045] Furthermore, during the process of transporting cigarette packs by the cigarette conveying device, the conveyor belt 100 will vibrate as the entire device operates. During this vibration, the pin shaft 221 may become detached from the bearing plate 222, causing the lug body 210 to fall off the conveyor belt 100. To prevent the lug body 210 from vibrating and falling off the conveyor belt 100, in this embodiment, the connecting assembly 220 further includes two stoppers (not shown in the figure), which are respectively connected to the ends of the pin shaft 221 on the side facing away from the corresponding bearing plate 222.

[0046] Specifically, the limiting member is configured as one or more of a limiting pin, a limiting ring or a limiting nut.

[0047] When the limiting member is set as a limiting pin, correspondingly, limiting holes are provided at both ends of the pin shaft 221. After the two ends of the pin shaft 221 are respectively inserted into the two connecting holes 2221, the two limiting pins are inserted into the two limiting holes one by one to limit the relative position between the pin shaft 221 and the two bearing plates 222.

[0048] When the limiting member is set as a limiting ring, correspondingly, connecting grooves are provided at both ends of the pin shaft 221, and the connecting grooves extend in a ring shape along the circumference of the pin shaft 221; after the two ends of the pin shaft 221 are respectively inserted into the two connecting holes 2221, the two limiting rings are correspondingly clamped in the two limiting rings to limit the relative position between the pin shaft 221 and the two bearing plates 222.

[0049] When the limiting member is set as a limiting nut, correspondingly, both ends of the pin shaft 221 are provided with external thread sections; after the two ends of the pin shaft 221 are respectively inserted into the two connecting holes 2221, the two limiting nuts are threadedly connected to the two external thread sections one by one to limit the relative position between the pin shaft 221 and the two bearing plates 222.

[0050] The limiting member can be set in one of the above structures, or multiple structures can be matched; alternatively, one end of the pin 221 is integrally formed with a protrusion, and the other end is set with the above structure.

[0051] Implementation Method 2

[0052] Preferably, the lug mechanism 200 also includes an installation component 230, and the connecting component 220 includes two clips 223; each clip 223 includes a connecting portion 2231 and a clip 2232 arranged perpendicular to each other, wherein one connecting portion 2231 is fixedly connected to the lug body 210, and the other connecting portion 2231 is movably connected to the lug body 210 through the installation component 230, and the two clips 2232 are arranged opposite to each other.

[0053] The two clamping parts 2232 are arranged opposite to each other, and cooperate with the two connecting parts 2231 and the lug body 210 to form a clamping space; when installing the lug body 210, first bend the connecting part 2231 that is movably connected to the lug body 210 to make the movably connected connecting part 2231 move in the direction away from the fixedly connected connecting part 2231, and then clamp the clamping space to the target position on the conveyor belt 100, and then reset the movably connected connecting part 2231 to the initial position; in this state, the two connecting parts 2231 respectively abut against the two side walls of the conveyor belt 100 one by one, and the two clamping parts 2232 are clamped between two adjacent conveying teeth 110 of the same group; when the lug body 210 needs to be replaced, the connecting part 2231 that is movably connected to the lug body 210 is bend again in the direction away from the fixedly connected connecting part 2231.

[0054] In order to further enhance the strength of the lug mechanism 200 , the fixed connection portion 2231 is integrally formed with the lug body 210 . Alternatively, both connection portions 2231 may be movably connected to the lug body 210 via the mounting assembly 230 .

[0055] Specifically, the mounting assembly 230 includes a slide rail 231, a slide groove 232 and an elastic member 233; the slide rail 231 is arranged on one of the connecting portion 2231 and the lug body 210, and the slide groove 232 is arranged on the other, the slide groove 232 extends along the X direction, the slide rail 231 is slidably connected to the slide groove 232, and the two ends of the elastic member 233 are respectively connected to the first side wall 2321 of the slide groove 232 and the slide rail 231.

[0056] In this embodiment, the slide groove 232 is arranged on the lug body 210, and the slide groove 232 extends along the X direction but does not pass through the lug body 210; the elastic member 233 is arranged as a tension spring, and the slide rail 231 is arranged on the side of the connecting portion 2231 close to the lug body 210, and one end of the tension spring is fixedly connected to the first side wall 2321, and the other end is fixedly connected to the slide rail 231. When installing the lug body 210, the connecting portion 2231 is moved in a direction away from the first side wall 2321. The connecting portion 2231 drives the slide rail 231 to slide in the slide groove 232 in a direction away from the first side wall 2321. During this process, the tension spring is stretched by the external force. After the clamping space is clamped to the target position on the conveyor belt 100, the connecting portion 2231 is no longer moved. At this time, the tension spring is no longer subjected to the external force and begins to retract to its original state. During this process, the tension spring drives the slide rail 231 and the connecting portion 2231 to return to their initial positions, so that the two connecting portions 2231 respectively abut against the two side walls of the conveyor belt 100 in a one-to-one correspondence, and the two clamping portions 2232 are clamped between two adjacent conveying teeth 110 in the same group. During the entire process, after the clamping space is clamped to the target position on the conveyor belt 100, no further operation is required to complete the installation of the lug body 210, ensuring the installation effect while further improving the installation convenience.

[0057] Furthermore, the width of the chute 232 gradually decreases from the bottom wall to the open end of the chute 232, and the slide rail 231 is arranged corresponding to the chute 232. Along the X-direction, the cross-sectional shape of the chute 232 can be configured as a dovetail, a trapezoid, or an inverted "T" shape; this configuration can prevent the slide rail 231 from separating from the chute 232 in the depth direction of the chute 232, thereby further improving the installation effect of the lug body 210.

[0058] Furthermore, a guide channel 2311 is provided on the bottom wall of the sliding groove 232 or the sliding rail 231 , and the elastic member 233 is disposed in the guide channel 2311 .

[0059] like Figure 3 As shown, in this embodiment, the guide channel 2311 is arranged on the side of the slide rail 231 close to the slide groove 232. The guide channel 2311 extends along the X direction but does not pass through the slide rail 231. One end of the tension spring is fixedly connected to the first side wall 2321, and the other end is fixedly connected to the bottom wall of the guide channel 2311. When the compression spring is stretched or retracted autonomously, the guide channel 2311 guides the compression channel to move along a predetermined route, thereby ensuring the use effect of the compression spring.

[0060] Implementation Method 3

[0061] Specifically, the mounting assembly 230 includes a threaded connector (not shown in the figures), and the connecting portion 2231 is movably connected to the lug body 210 via the threaded connector.

[0062] When the lug body 210 needs to be replaced, the two connecting parts 2231 are respectively in contact with the two side walls of the conveyor belt 100, and the two connecting parts 2232 are clamped between the two adjacent conveying teeth 110 of the same group. When the lug body 210 needs to be replaced, the threaded connection part 223 is loosened again and the connecting part 223 is removed from the lug body 210.

[0063] In order to further enhance the strength of the lug mechanism 200 and reduce the probability of breakage or damage of the lug body 210 , in the three embodiments, the lug mechanism 200 is configured as a metal component.

[0064] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
