The utility model relates to an adsorption type offset paper tipping device, which comprises a conveying track 1 for conveying cigarette cartons 4, a paper sucking mechanism 2 for adsorbing or loosening offset paper 41 in the cigarette cartons 4, and a paper tipping mechanism 3 for driving the paper sucking mechanism 2 to tip; the cigarette pack feeding level is arranged on the conveying rail 1, the conveying rail 1 stops when the cigarette cartons 4 are conveyed to the cigarette pack feeding level, the paper turning mechanism 3 drives the paper sucking mechanism 2 to turn over towards the direction close to the cigarette cartons 4, the paper sucking mechanism 2 adsorbs offset printing sulfuric acid paper 41 in the cigarette cartons 4, the paper turning mechanism 3 drives the paper sucking mechanism 2 to turn over towards the direction far away from the cigarette cartons 4, the paper sucking mechanism 2 drives the offset printing sulfuric acid paper 41 to turn out of the cigarette cartons 4, after cigarettes are packed in the cigarette cartons 4, the conveying rail 1 conveys the cigarette cartons 4 forwards again, meanwhile, the paper sucking mechanism 2 loosens the offset printing sulfuric acid paper 41, and the offset printing sulfuric acid paper 41 automatically covers the cigarettes in the cigarette cartons 4.

In the actual production process, one end of the offset printing sulfuric acid paper 41 is fixedly connected with the cavity of the cigarette carton 4, and after the production of the cigarette carton 4 is finished, the offset printing sulfuric acid paper 41 is synchronously arranged in the cavity of the cigarette carton 4. When the cigarette pack is loaded into the cavity of the cigarette pack 4, the offset paper 41 needs to be manually turned out of the cavity of the cigarette pack 4, so that the cigarette pack loaded in the cavity of the cigarette pack 4 does not press the offset paper 41 against the bottom of the cavity. After the cigarette package is carried, the offset printing sulfuric acid paper 41 is turned back through the manual work, and is covered on the cigarette package, so that the cigarette package is isolated from the outside, the cigarette package is prevented from being wetted, more manpower and time are wasted in the process, the production efficiency is low, and the current production requirement is not met.

In the application, a tobacco package loading level is arranged on a transportation track 1, when the transportation track 1 transports a cigarette carton 4 to the tobacco package loading level, the transportation track 1 stops running, and a paper turning mechanism 3 drives a paper sucking mechanism 2 to turn towards a direction close to the cigarette carton 4, so that the paper sucking mechanism 2 can adsorb offset printing sulfuric acid paper 41 in the cigarette carton 4; after the paper sucking mechanism 2 adsorbs the offset printing kraft paper 41, the paper turning mechanism 3 drives the paper sucking mechanism 2 to turn over in the direction away from the cigarette carton 4, so that the paper sucking mechanism 2 drives the offset printing kraft paper 41 to turn out from the cigarette carton 4, and a cigarette packet is loaded in a cavity in the cigarette carton 4; after the cigarette packaging is completed, the conveying track 1 is restarted to drive the cigarette cartons 4 to continue to be conveyed forwards, meanwhile, the offset printing sulfuric acid paper 41 is loosened by the paper sucking mechanism 2, when the cigarette cartons 4 pass below the paper sucking mechanism 2, the offset printing sulfuric acid paper 41 automatically covers the cigarette cartons of the cigarette cartons 4 under the abutting of the paper sucking mechanism 2, so that the offset printing sulfuric acid paper 41 is overturned from the cavity of the cigarette cartons 4 instead of manually, and the offset printing sulfuric acid paper 41 is overturned to cover the cigarette cartons, the time and the labor are saved, the labor intensity of workers is reduced, and meanwhile, the production efficiency is improved.

It is envisioned that: the direction in which the transporting rail 1 transports the cigarette cartons 4 is the front, i.e., the transporting rail 1 transports the cigarette cartons 4 forward. When the paper sucking mechanism 2 is initially positioned in front of the tobacco bale loading level of the conveying track 1, and when the cigarette carton 4 stops at the tobacco bale loading level, the paper turning mechanism 3 drives the paper sucking mechanism 2 to turn backwards, so that the paper sucking mechanism 2 can adsorb offset printing sulfuric acid paper 41 in the cigarette carton 4; when the adsorption is completed, the paper turning mechanism 3 drives the paper sucking mechanism 2 to turn forwards, so that the paper sucking mechanism 2 stops in front of the cigarette carton 4 and the offset printing sulfuric acid paper 41 in the cigarette carton 4 is pulled out; after the cigarette packet is loaded in the cigarette carton 4, the transportation track 1 continues to drive the cigarette carton 4 to be transported forwards, meanwhile, the offset paper sulfate 41 is loosened by the paper suction mechanism 2, and when the cigarette carton 4 passes below the paper suction mechanism 2, the offset paper sulfate 41 automatically covers the cigarette packet under the abutting of the paper suction mechanism 2.

In this embodiment, the paper sucking mechanism 2 includes a suction plate 21, a suction plate seat 22, and a negative pressure air pipe, the suction plate 21 is detachably mounted on the suction plate seat 22, a cavity 221 is provided in the suction plate seat 22, a plurality of first through holes 211 communicating the cavity 221 with the outside are provided on the suction plate 21, and the negative pressure air pipe extends into the cavity 221, and the specific effect is shown in fig. 4 and 5. The suction plate seat 22 is provided with a cavity 221, and the suction plate 21 is provided with a plurality of first through holes 211, and when the suction plate 21 is mounted on the suction plate seat 22, the first through holes 211 communicate the cavity 221 with the outside. The negative pressure air duct extends into the cavity 221, and it is envisioned that: the other end of the negative pressure air pipe is connected with the negative pressure fan, so that when the negative pressure fan is started, negative pressure is generated in the cavity 221 through the negative pressure air pipe. Since the first through hole 211 communicates the cavity 221 with the outside, when the suction plate 21 is in contact with the offset paper sulfate 41, the negative pressure in the cavity 221 adsorbs the offset paper sulfate 41 through the first through hole 211, thereby realizing adsorption of the offset paper sulfate 41 by the paper suction mechanism 2; when the negative pressure fan stops operating, the negative pressure of the cavity 221 disappears, and the suction force of the first through hole 211 to the offset paper 41 disappears, so that the release of the offset paper 41 by the paper suction mechanism 2 is realized.

In the prior art, the paper sucking mechanism 2 usually adopts a horn mouth suction nozzle to suck paper, and when the horn mouth suction nozzle sucks paper, the contact area between the suction force generated by the suction nozzle and the paper is small, so that the suction force is not easy to control. If the suction force is too small, the paper sucked by the suction nozzle is unstable and is easy to drop; if the suction force is too large, the paper may be deformed or even broken. In this application, the suction mechanism 2 adsorbs the offset paper 41 through the suction plate 21, and the outer side surface of the suction plate 21 contacts the offset paper 41 when the suction plate 21 adsorbs the offset paper 41, so that the contact area between the suction force of the suction plate 21 and the offset paper 41 is large, the adsorption of the offset paper 41 by the suction mechanism 2 is more stable, and the offset paper 41 is prevented from being deformed or damaged during adsorption.

In this embodiment, the suction plate seat 22 is provided with a threaded hole 222, the suction plate 21 is provided with a second through hole 212, and the paper suction mechanism 2 further includes a bolt 23 with one end penetrating through the second through hole 212 and screwed with the threaded hole 222, as shown in fig. 4 and 5. A threaded hole 222 is formed in the suction plate seat 22, a second through hole 212 is formed in the suction plate 21, the suction plate 21 is placed on the suction plate seat 22, the suction plate 21 covers the cavity 221 of the suction plate seat 22, meanwhile, the central axis of the threaded hole 222 is aligned with the central axis of the second through hole 212, one end of a bolt 23 penetrates through the second through hole 212 and then is in threaded connection with the threaded hole 222, and therefore the suction plate 21 is fixedly installed on the suction plate seat 22; when the bolts 23 are screwed out from the screw holes 222, the suction plate 21 is detachable from the suction plate holder 22, thereby achieving detachable mounting of the suction plate 21 on the suction plate holder 22.

In this application, so with suction plate 21 demountable installation on suction plate seat 22, when the damage appears in suction plate 21, need not change whole suction mechanism, only change suction plate 21 to save production material, make the practicality of this device stronger.

In this embodiment, a step for limiting the nut of the bolt 23 is disposed at the top of the second through hole 212, and when one end of the bolt 23 passes through the second through hole 212 and is screwed with the threaded hole 222, the top of the nut of the bolt 23 is located in the suction plate 21, and the specific effect is shown in fig. 4 and 5. A step is provided at the top of the second through hole 212, and when one end of the bolt 23 passes through the second through hole 212 and is screwed with the threaded hole 222 until the nut of the bolt 23 abuts against the step, thereby fixing the suction plate 21 on the suction plate seat 22. In this application, the nut of the bolt 23 is located in the suction plate 21 when the nut abuts against a step on the top of the suction plate 21. It is envisioned that: the second through hole 212 is a countersunk hole formed in the suction plate 21, and is formed in such a way that if the nut of the bolt 23 is directly abutted against the top of the suction plate 21, the suction plate 21 adsorbs the offset paper 41 due to the certain thickness of the nut, and a certain distance is formed between the outer side surface of the suction plate 21 and the offset paper 41 at the place where the bolt 23 exists, so that the outer side surface of the suction plate 21 cannot be well attached to the offset paper 41, and the adsorption effect of the suction mechanism on the offset paper 41 is affected.

And when the second through hole 212 is set as a countersunk hole, and one end of the bolt 23 penetrates through the second through hole 212 and is in threaded connection with the threaded hole 222, a step at the top of the countersunk hole can limit a nut of the bolt 23, so that the suction plate 21 is fixed on the suction plate seat 22 through the bolt 23, the nut of the bolt 23 is buried in the countersunk hole, and when the suction plate 21 adsorbs the offset printing kraft paper 41, a gap is formed between the outer side surface of the suction plate 21 and the offset printing kraft paper 41, and the adsorption effect of the suction mechanism on the offset printing kraft paper 41 is affected.

In this embodiment, the suction plate 21 is an arc plate, and a plurality of suction grooves 213 are formed on the outer side surface of the arc plate along the circumferential direction, and a plurality of first through holes 211 are formed in one suction groove 213, as shown in fig. 5. In this application, set up the suction plate 21 into the arc, when in order to prevent paper turning over mechanism 3 drive suction plate 21 to be close to or keep away from cigarette barrel 4 direction upset, produce the interference with the box body of cigarette barrel 4 to both make things convenient for suction plate 21 to adsorb offset printing template 41 in the cigarette barrel 4, make things convenient for suction plate 21 to turn over offset printing template 41 in the cavity 221 of cigarette barrel 4 again. A plurality of adsorption grooves 213 are provided on the outer side surface of the suction plate 21 in the circumferential direction, and a plurality of first through holes 211 communicating the suction plate holder 22 with the outside are provided in each adsorption groove 213, so that negative pressure is generated in the adsorption groove 213 through the first through holes 211 to adsorb the offset printing kraft paper 41. The suction groove 213 is provided on the outer side surface of the suction plate 21 to increase the area of the negative pressure region on the outer side surface of the suction plate 21, thereby increasing the contact area between the suction force and the offset paper 41, and improving the suction effect of the suction plate 21 on the offset paper 41.

In this embodiment, the top of two sides of the adsorption groove 213 is provided with arc chamfers 2131, which has a specific effect as shown in fig. 5. Since the suction plate 21 adsorbs the offset paper 41, when the outer side surface of the suction plate 21 is stuck to the offset paper 41, the offset paper 41 is adsorbed to the outer side surface of the suction plate 21 by the negative pressure in the adsorption tank 213. It is envisioned that: since the suction groove 213 is recessed downward on the outer side surface of the suction plate 21, when the negative pressure in the suction groove 213 sucks the offset paper sheet 41 attached to the outer side surface of the suction plate 21, the offset paper sheet 41 may be sucked into the suction groove 213 due to a large suction force, and the offset paper sheet 41 may be deformed. Therefore, in this application, the arc chamfer 2131 is provided at the top of two sides of each adsorption groove 213, so that when the offset printing kraft paper 41 is attached to the outer side surface of the suction plate 21, a gap is formed between the offset printing kraft paper 41 and the adsorption grooves 213, so that the adsorption grooves 213 are communicated with the outside, and the offset printing kraft paper 41 is not excessively adsorbed into the adsorption grooves 213, thereby causing deformation of the offset printing kraft paper 41.
