Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging equipment technology, and in particular to an anti-skid device and a packaging machine. Background Technology

[0002] The pull tab on cigarette packs, also known as the opening line, is the opening strip for removing the outer packaging film. The pull tab not only facilitates opening the cigarette pack but also incorporates several high-tech features such as laser holography, fluorescent color-changing, microfilm storage, and special plate making, providing strong anti-counterfeiting capabilities. The accurate positioning of the pull tab on the outer packaging film is crucial, ensuring consumers can easily open the cigarette pack. The YB95 packaging machine is a carton transparent paper packaging machine that wraps an additional layer of transparent paper around the already formed carton for aesthetic purposes, moisture retention, and protection, and then attaches the pull tab to the transparent paper.

[0003] In the YB95 packaging machine, the pull cord is transported by the conveyor roller. However, when the machine starts or stops or the speed changes, the pull cord will vibrate. When the vibration amplitude exceeds the edge height of the conveyor roller, the pull cord will jump off the conveyor roller, which will cause the pull cord to be misaligned with the transparent paper. This will cause the pull cord to be out of the U-shaped cutting position of the transparent paper, resulting in the defect that the pull cord cannot be locked open.

[0004] Therefore, there is an urgent need to propose an anti-skid-out device and packaging machine that can effectively solve the problem of skipped threads. Utility Model Content

A receiving groove is recessed on the circumferential sidewall of the conveyor wheel. A pull wire is wound around the circumferential sidewall of the conveyor wheel and located within the receiving groove. The anti-drop wire device includes:

[0008] The mounting bracket extends along a first direction and can be installed below the support. The mounting bracket is provided with a stop block, and the stop block and the mounting bracket are arranged along a second direction and connected to each other.

[0009] A baffle plate is arranged and connected to the mounting frame along the second direction. The baffle plate includes a connecting portion and a limiting portion arranged and connected to each other along the first direction. The connecting portion is rotatably connected to the mounting frame, such that the limiting portion is a first preset distance or a second preset distance from the circumferential sidewall of the conveyor wheel. When the limiting portion abuts against the stop block, the limiting portion is a first preset distance from the circumferential sidewall of the conveyor wheel to prevent the pull wire from leaving the receiving groove. When the limiting portion is spaced apart from the stop block, the limiting portion is a second preset distance from the circumferential sidewall of the conveyor wheel, and the pull wire can leave the receiving groove.

[0010] Preferably, the mounting bracket is provided with a connecting hole whose axis extends along the second direction, and the connecting part is provided with a connecting shaft whose axis extends along the second direction. The connecting shaft is placed in the connecting hole and can rotate within the connecting hole.

[0011] Preferably, the anti-jump cable device further includes a reset member, one end of which is connected to the wall of the connecting hole and the other end is connected to the connecting shaft, so that the limiting part has a tendency to abut against the stop block.

[0012] Preferably, the reset element is a torsion spring.

[0013] Preferably, the stop block and the mounting bracket are integrally formed.

[0014] Preferably, the mounting bracket is provided with a first mounting hole extending along a third direction, and the support is provided with a second mounting hole extending along the third direction. The fastener passes through the first mounting hole and the second mounting hole in sequence to fix the mounting bracket on the support.

[0015] Preferably, the limiting part has a chamfered structure at the edge facing the conveyor wheel.

[0016] Preferably, the first preset distance is in the range of 3~5mm.

[0017] Preferably, the limiting portion extends along the second direction, the width direction of the receiving groove is parallel to the second direction, and the dimension of the limiting portion in the second direction is not less than the width of the receiving groove.

[0018] A packaging machine includes a support, a conveyor wheel, and the aforementioned anti-drop-line device. The conveyor wheel and the support are spaced apart along a second direction, and the anti-drop-line device is mounted on the support to prevent the pull line from detaching from the conveyor wheel.

[0019] The beneficial effects of this utility model are:

[0020] This utility model proposes an anti-skid wire device that can be installed on a bracket. The bracket extends along a first direction, and a conveyor wheel and the bracket are spaced apart along a second direction. A receiving groove is recessed on the circumferential side wall of the conveyor wheel. The pull wire is wound around the circumferential side wall of the conveyor wheel and located within the receiving groove. The width direction of the receiving groove is parallel to the second direction. The anti-skid wire device includes a mounting frame and a baffle. The mounting frame extends along the first direction and can be installed below the bracket. A baffle is provided on the mounting frame. The baffle and the mounting frame are arranged along the second direction and connected to each other. The baffle and the mounting frame are arranged and connected along the second direction. The baffle includes a connecting part and a limiting part arranged and connected to each other along the first direction. The limiting part extends along the second direction. The connecting part is rotatably connected to the mounting frame, so that the limiting part is a first preset distance or a second preset distance from the circumferential side wall of the conveyor wheel. When the limiting part abuts against the stop block, the limiting part is a first preset distance from the circumferential side wall of the conveyor wheel to prevent the pull wire from leaving the receiving groove. When the limiting part and the stop block are spaced apart, the limiting part is a second preset distance from the circumferential side wall of the conveyor wheel, and the pull wire can leave the receiving groove. When the baffle rotates to the point where the limiting part abuts against the stop block, the limiting part is a first preset distance away from the circumferential side wall of the conveyor wheel. At this time, the limiting part acts as a guardrail, preventing the pull cable from jumping significantly, thus physically preventing the pull cable from jumping out of the receiving groove. When the pull cable needs to be replaced, the baffle is rotated to make the limiting part and the stop block spaced apart, and the limiting part is a second preset distance away from the circumferential side wall of the conveyor wheel, thus leaving enough clearance space so that the pull cable replacement process is not obstructed by the baffle.

[0021] On the other hand, this utility model also proposes a packaging machine, including a support, a conveyor wheel and the aforementioned anti-drop-line device. The conveyor wheel and the support are spaced apart along a second direction. The anti-drop-line device is installed on the support to prevent the pull line from detaching from the conveyor wheel. This packaging machine has high packaging efficiency. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0032] Reference Figures 1 to 4This embodiment proposes an anti-skid wire device that can be installed on a bracket 10. The bracket 10 extends along a first direction, and the conveyor wheel 20 and the bracket 10 are spaced apart along a second direction. A receiving groove is recessed on the circumferential side wall of the conveyor wheel 20. The pull wire is wound around the circumferential side wall of the conveyor wheel 20 and located in the receiving groove. The width direction of the receiving groove is parallel to the second direction. The anti-skid wire device includes a mounting frame 1 and a baffle 3. The mounting frame 1 extends along the first direction and can be installed below the bracket 10. A baffle 2 is provided on the mounting frame 1. The baffle 2 and the mounting frame 1 are arranged along the second direction and connected to each other. The baffle 3 is connected to the bracket 1. The mounting bracket 1 is arranged and connected along the second direction. The baffle 3 includes a connecting part 31 and a limiting part 32 arranged and connected along the first direction. The limiting part 32 extends along the second direction. The connecting part 31 is rotatably connected to the mounting bracket 1, so that the limiting part 32 is a first preset distance or a second preset distance from the circumferential side wall of the conveyor wheel 20. When the limiting part 32 abuts against the stop block 2, the limiting part 32 is a first preset distance from the circumferential side wall of the conveyor wheel 20 to prevent the pull wire from leaving the receiving groove. When the limiting part 32 and the stop block 2 are spaced apart, the limiting part 32 is a second preset distance from the circumferential side wall of the conveyor wheel 20, and the pull wire can leave the receiving groove. When the baffle 3 rotates to the point where the limiting part 32 abuts against the stop block 2, the limiting part 32 is a first preset distance away from the circumferential side wall of the conveyor wheel 20. At this time, the limiting part 32 acts as a guardrail, preventing the pull cable from jumping significantly, thus physically preventing the pull cable from jumping out of the receiving groove. When the pull cable needs to be replaced, the baffle 3 is rotated so that the limiting part 32 and the stop block 2 are spaced apart, and the limiting part 32 is a second preset distance away from the circumferential side wall of the conveyor wheel 20, thus leaving enough clearance space so that the pull cable replacement process is not obstructed by the baffle 3.

[0033] It is understandable that the second preset distance is much larger than the first preset distance. During the normal transport of the cable on the conveyor wheel 20, the limiting part 32 of the baffle 3 abuts against the stop block 2. At this time, the distance between the limiting part 32 and the circumferential side wall of the conveyor wheel 20 is exactly the first preset distance. The first preset distance is small, which can ensure that the cable will not fall out of the receiving groove. When it is necessary to replace the cable on the conveyor wheel 20, the first preset distance will obviously make the baffle 3 obstruct the cable replacement process. At this time, the connecting part 31 of the baffle 3 can be rotated relative to the mounting frame 1, so that the limiting part 32 of the baffle 3 moves away from the stop block 2, until the distance between the limiting part 32 and the circumferential side wall of the conveyor wheel 20 is the second preset distance. The second preset distance is larger, which can provide a larger working space and facilitate the workers to replace the cable.

[0034] The first preset distance is 3~5mm. This distance ensures that the limiting part 32 of the baffle 3 can block the receiving groove on the conveyor wheel 20, preventing the pull wire from leaving the receiving groove. In addition, within the above-mentioned range, the baffle 3 does not directly contact the circumferential side wall of the conveyor wheel 20. Since the conveyor wheel 20 rotates at high speed during operation, if the baffle 3 directly contacts the circumferential side wall of the conveyor wheel 20 to close the receiving groove, it will cause continuous friction, which will reduce the service life of the components, such as the baffle 3 or the circumferential side wall of the conveyor wheel 20. Moreover, if the baffle 3 directly contacts the circumferential side wall of the conveyor wheel 20, and if the number of turns of the pull wire in the receiving groove is large, the baffle 3 may squeeze the pull wire, causing the surface of the pull wire to be scratched or even broken.

[0035] Furthermore, the stop block 2 provides a rigid limit to the baffle plate 3, ensuring that the distance between the limiting part 32 of the baffle plate 3 and the circumferential surface of the conveyor wheel 20 is a first preset distance. In this embodiment, the stop block 2 and the mounting bracket 1 are integrally formed structures; specifically, they can be welded or directly stamped.

[0036] In this embodiment, both the first direction and the second direction are horizontal, and the first direction and the second direction are set perpendicularly.

[0037] Furthermore, the mounting bracket 1 is provided with a connecting hole whose axis extends along the second direction, and the connecting part 31 is provided with a connecting shaft whose axis extends along the second direction. The connecting shaft is placed in the connecting hole and can rotate within the connecting hole. The mounting bracket 1 and the baffle 3 are rotatably connected through the mutual cooperation of the connecting hole and the connecting shaft. Of course, in other embodiments, the mounting bracket 1 may also be provided with a shaft whose axis extends along the second direction, and the connecting part 31 may be provided with a hole whose axis extends along the second direction, with the shaft placed in the hole and rotatably connected within the hole. Alternatively, in more embodiments, the mounting bracket 1 and the connecting part 31 may also be connected by a hinge, as long as a rotatable connection between the mounting bracket 1 and the connecting part 31 can be achieved.

[0038] The anti-slip wire device also includes a reset member, one end of which is connected to the wall of the connecting hole, and the other end is connected to the connecting shaft, so that the limiting part 32 tends to abut against the stop block 2. The reset member applies a constant restoring force to force the connecting part 31 of the baffle 3 to rotate until the limiting part 32 abuts against the stop block 2. At this time, the limiting part 32 is at a first preset distance from the circumferential side wall of the conveying wheel 20, effectively covering the upper edge of the receiving groove and preventing the pull wire from falling out of the receiving groove due to vibration, centrifugal force or external impact during operation. It is understandable that when the limiting part 32 abuts against the stop block 2, it is the default position of the stop plate 3. The setting of the reset member makes the stop plate 3 tend to return to the default position. The reset member stores energy by elastic deformation. When the operator moves the stop plate 3 to replace the pull cable, the connecting shaft rotates in the connecting hole, and the reset member is twisted. When the operator finishes replacing the pull cable, the force applied to the stop plate 3 is removed, the reset member releases energy, and drives the stop plate 3 to automatically return to the default position. This can ensure that the limiting part 32 and the circumferential surface of the conveyor wheel 20 are at the first predetermined distance, avoiding the failure of the cable derailment caused by human negligence or environmental factors.

[0039] In this embodiment, the reset component is a torsion spring. The torsion spring is in the shape of a helical coil, with spring legs extending from both ends. The torsion spring is sleeved on the connecting shaft, with one spring leg fixed to the connecting shaft and the other spring leg fixed to the wall of the connecting hole.

[0040] Additionally, the mounting bracket 1 is provided with a first mounting hole 11 extending along a third direction, and the bracket 10 is provided with a second mounting hole extending along a third direction. A fastener (not shown in the figure) passes through the first mounting hole 11 and the second mounting hole in sequence to fix the mounting bracket 1 to the bracket 10. In this embodiment, the fastener is a bolt, which, through threaded engagement with the first mounting hole 11 and the second mounting hole, fixes the mounting bracket 1 to the lower side of the bracket 10. The third direction is the vertical direction.

[0041] The limiting part 32 has a chamfered structure at the edge facing the conveyor wheel 20. On the one hand, it can optimize the user experience of the staff and avoid the sharp edge from scratching the staff. On the other hand, when the pull cable vibrates, the chamfered structure can avoid the cutting effect of the right angle edge on the pull cable, further protecting the pull cable and preventing its surface from being scratched.

[0042] The limiting part 32 extends along the second direction, and the width direction of the receiving groove is parallel to the second direction. The dimension of the limiting part 32 in the second direction is not less than the width of the receiving groove. The axis of the conveyor wheel 20 is parallel to the second direction, and the dimension of the limiting part 32 in the second direction is not less than the width of the receiving groove on the conveyor wheel 20. This allows for complete coverage in the width direction of the receiving groove, forming a physical barrier without blind spots and avoiding the risk of edge delamination due to insufficient size of the baffle 3.

[0043] On the other hand, this embodiment also proposes a packaging machine, including a support 10, a conveyor wheel 20, and the aforementioned anti-skid-line device. The conveyor wheel 20 and the support 10 are spaced apart along a second direction. The anti-skid-line device is installed on the support 10 to prevent the pull line from detaching from the conveyor wheel 20. This packaging machine has high packaging efficiency. The anti-skid-line device ensures that the pull line remains within the receiving groove on the conveyor wheel 20 during equipment operation, avoiding the need for machine stoppage for adjustments, greatly improving packaging efficiency, and simultaneously improving product packaging quality.

[0044] The conveyor wheel 20 and the support 10 are spaced apart along the second direction. A drive shaft is provided between the conveyor wheel 20 and the support 10. The axis of the drive shaft extends along the second direction. One end of the drive shaft is rotatably connected to the support 10, and the other end is fixedly connected to the conveyor wheel 20, so that the conveyor wheel 20 can rotate on the support 10.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
