Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cigarette processing and packaging equipment, and particularly relates to a novel cigarette packet anti-reverse device for the extractor of a ZB416 hard box packaging machine. Background Art
[0002] ZB416 is a high-speed cigarette machine equipment introduced and launched by Shanghai Tobacco Machinery Factory in recent years. It has been popularized in cigarette factories across the country. The machine speed of this model reaches 500 packs per minute. The cigarette packets coming out of the main machine drying beam are sucked out by two upper and lower suction cups and sent to the conveying toothed belt, and then the toothed belt sends the cigarette packets to the overhead cigarette packet conveying belt. The negative pressure is always on during the process of the suction cup sucking the cigarette packet. Since the suction cup needs to release the cigarette packet after sucking it to the designated position, but the negative pressure is always on, after the cigarette packet reaches the designated position, a baffle is used to block the cigarette packet, while the suction cup still continues to move backward. Therefore, the cigarette packet is forcibly blocked at the designated position. Since the negative pressure is forcibly disconnected, a reaction force is formed on the cigarette packet, and an elastic baffle needs to be installed to prevent the cigarette packet from tilting under the action of the impact force.
[0003] The original device uses an elastic baffle to block the cigarette packet in the middle of the cigarette packet passage. Due to the large reaction force of the cigarette packet, only installing the elastic baffle in the middle still poses a risk of the cigarette packet tilting. If the cigarette packet tilts, it is easy to be hit, affecting the conveying of the cigarette packet. Moreover, the service life of the elastic baffle is relatively short. When the elasticity of the elastic baffle is lost, it can no longer play a blocking role, which will further cause the risk of cigarette packet tilting and wrinkling, affecting the conveying of the cigarette packet and the quality of the cigarette packet.

The upper end surface of the upper bottom plate 11 is used for the passage of the cigarette packets. At least two installation grooves 121 are formed on the lower bottom plate 12. The number of the installation grooves 121 is equal to the number of the anti-reverse grooves 111. The anti-reverse grooves 111 and the installation grooves 121 are communicated.
[0044] Among them, in this embodiment, the thickness of the upper bottom plate 11 is 4 mm, and the thickness of the lower bottom plate 12 is 6 mm.
[0045] The cigarette packet baffle 20 is connected to one end of the channel bottom plate 10.
[0046] Specifically, the cigarette packet baffle 20 is connected to the end of the channel bottom plate 10 away from the cigarette packet feeding direction. In this embodiment, the cigarette packet baffle 20 is detachably connected to the channel bottom plate 10 by a third bolt 21. The upper end surface of the cigarette packet baffle 20 is higher than the upper end surface of the channel bottom plate 10, and is used to block the cigarette packet so that it falls from the suction cup onto the channel bottom plate 10.
[0047] At least two of the anti-reverse components 30 are arranged side by side and spaced apart on the channel bottom plate 10. The connection line of at least two of the anti-reverse components 30 is perpendicular to the passing direction of the cigarette packet. The anti-reverse component 30 includes an anti-reverse hook 31 and a spring 32. The first end of the anti-reverse hook 31 away from the cigarette packet baffle is rotatably connected to the inside of the channel bottom plate 10, and the opposite second end penetrates through the upper end surface of the channel bottom plate 10 through the anti-reverse groove 111. One end of the spring 32 is connected to the bottom of the second end of the anti-reverse hook 31, and the other end is connected to the channel bottom plate 10.
[0048] Specifically, the first end of the anti-reverse hook 31 is rotatably connected to the installation groove 121 and the anti-reverse groove 111 through a rotating shaft 33. Both ends of the rotating shaft 33 are connected to the lower bottom plate 12 and the upper bottom plate 11, and are placed at the upper end of the installation groove 121. The first end of the anti-reverse hook 31 is rotatably sleeved on the rotating shaft 33. Each spring 32 is located in a connected installation groove 121 and an anti-reverse groove 111. One end of it is connected to the bottom of the second end of the anti-reverse hook 31, and the other end is connected to the lower bottom plate 12 through a connection component. The connection component includes a pin shaft installation plate 34, a second bolt 35 and a pin shaft 36.

One end of the pin shaft 36 is connected to the pin shaft installation plate 34, and the other end is connected to the spring 32. Preferably, a fixing groove is provided at the end of the pin shaft 36 connected to the spring 32. The spring 32 is connected to the pin shaft 36 through the fixing groove. Define the groove width of the fixing groove as H, and the wire diameter of the spring 32 as h, then H = h is satisfied, so that the spring 32 can be tightly clamped into the fixing groove, increasing the connection stability between the spring 32 and the pin shaft 36.
[0049] Among them, in this embodiment, the long side of the anti-reverse hook 31 in the same vertical plane as the passing direction of the cigarette packet is 40 mm, the wide side of the anti-reverse hook 31 perpendicular to the passing direction of the cigarette packet is 10 mm, the shaft diameter of the rotating shaft 33 is 3 mm, the number of the anti-reverse components 30 is two, so the number of the rotating shafts 33 is two. One end of the rotating shaft 33 close to the side of the channel bottom plate 10 penetrates through the side of the channel bottom plate 10 and is located outside the channel bottom plate 10. The wire diameter of the spring 32 is 0.5 mm, the outer diameter is 5 mm, and the length is 15 mm.
[0050] In some embodiments, the upper bottom plate 11 is made of stainless steel, and the lower bottom plate 12 is made of aluminum. By setting the material of the upper bottom plate 11 in contact with the cigarette pack to wear-resistant stainless steel, the service life of the channel bottom plate 10 is improved. By using the inexpensive aluminum material for the lower bottom plate 12, the overall production cost of the channel bottom plate 10 is reduced. At the same time, when the channel bottom plate 10 needs to be replaced, only the upper bottom plate 11 needs to be replaced, further reducing the production cost.
[0051] In some embodiments, a fixing hole is provided at the bottom of the second end of the anti-reverse hook 31, and the spring 32 is embedded in the fixing hole to be connected to the anti-reverse hook 31. By providing the fixing hole at the bottom of the anti-reverse hook 31, it effectively prevents the spring 32 from detaching from the anti-reverse hook 31 during long-term high-frequency use, increasing the practicality and service life of this application. Preferably, a smooth slope protrusion 311 can also be provided at the top of the second end of the anti-reverse hook 31, so that the cigarette pack can pass through the anti-reverse hook 31 more smoothly.
[0052] Among them, in this embodiment, the aperture of the fixing hole is 5.5 mm.
[0053] In some embodiments, the anti-reverse hook 31 is made of carbon fiber to increase the service life of the anti-reverse hook 31.
[0054] In some embodiments, the spring 32 is made of stainless steel to increase the service life of the spring 32.
[0055] In some embodiments, a rubber buffer pad 312 is provided on the end face of the anti-reverse hook 31 facing the cigarette pack baffle 20, providing a soft buffer between the cigarette pack and the anti-reverse hook 31, further preventing the cigarette pack from making hard contact with the anti-reverse component 30 under the action of the recoil force and wrinkling the packaging of the cigarette pack.
[0056] In summary, a new type of cigarette packet anti-reverse device for the extractor of the ZB416 hard box packaging machine provided by the embodiments of the present application can effectively prevent the cigarette packets from skewing under the action of the recoil force by arranging at least two anti-reverse components on the channel bottom plate, with at least two anti-reverse components arranged side by side at intervals, and the connection line of at least two anti-reverse components being perpendicular to the passing direction of the cigarette packets, solving the technical problems in the prior art that the cigarette packets skew and are collided due to only using a single elastic stop piece to block the cigarette packets. At the same time, by setting a spring and an anti-reverse hook to replace the elastic stop piece in the prior art, the technical problems in the prior art that the elastic stop piece loses its function of blocking the cigarette packets due to its short service life, resulting in the cigarette packets skewing and the cigarette packet packaging becoming wrinkled are solved; at the same time, by setting the channel bottom plate to be composed of an upper bottom plate and a lower bottom plate, the material of the upper bottom plate in contact with the cigarette packets is stainless steel, and the material of the lower bottom plate is aluminum. By replacing the integrally designed aluminum alloy bottom plate in the prior art with a split-type channel bottom plate, while reducing the overall cost of the channel bottom plate, the wear-resistant stainless steel upper bottom plate is used to increase the service life of the channel bottom plate, and when the channel bottom plate needs to be replaced, only the upper bottom plate needs to be replaced, further reducing the production cost; by setting a fixing hole at the bottom of the second end of the anti-reverse hook, it effectively avoids the spring from detaching from the anti-reverse hook during long-term high-frequency use, increasing the practicability and service life of the present application; by setting the material of the anti-reverse hook to be carbon fiber and the material of the spring to be stainless steel, the service life of the anti-reverse components in the present application is improved; by setting a rubber buffer pad on the end face of the anti-reverse hook facing the cigarette packet baffle, there is a soft buffer between the cigarette packet and the anti-reverse hook, further preventing the problem that the cigarette packet contacts the anti-reverse component under the action of the recoil force and the cigarette packet packaging becomes wrinkled.
