Example one

As shown in fig. 1 to 11, a high-speed dotting and cutting machine comprises a frame 10, and a film spreading assembly 20, a film feeding assembly 30 and a sealing dotting and cutting mechanism 40 which are sequentially arranged on the frame 10;

the film spreading assembly 20 is used for spreading the film, and the film feeding assembly 30 is used for conveying the film to the sealing and point-cutting mechanism 40 for sealing and point-cutting;

the sealing and spot-breaking mechanism 40 comprises a sealing knife 401, a beam 402, a balance adjusting and fixing component 403, a first bottom plate 404, a spot-breaking knife 405, a spot-breaking knife adjusting guide rod 406, a base 407 and a transmission component 408;

the sealing knife 401 is connected with the cross beam 402 through the balance adjustment fixing component 403, the point breaking knife 405 is connected with the base 407 through the point breaking knife adjustment guide rod 406, the sealing knife 401 is located above the bottom plate, and the point breaking knife 405 is arranged on one side of the first bottom plate 404 in parallel;

the transmission assembly 408 is connected with the beam 402 and the base 407, and the transmission assembly 408 drives the beam 402 and the base 407 to move up and down, so as to drive the seal cutter 401 and the point breaking cutter 405 to move up and down.

The point cutting machine is a core part of a machine for manufacturing the film bags, and is combined with a feeding machine, a blanking machine and the like to form a complete film bag production machine. The spot cutting machine mainly has the functions of sealing and spot cutting the film to produce individual film bags. The film spreading assembly 20, the film feeding assembly 30 and the sealing point-cutting mechanism 40 are all arranged on the rack 10; the film spreading assembly 20 is used for flattening the film to be sealed and cut by point cutting; the flattened film is transferred from the film spreading assembly 20 to the film feeding assembly 30; the film feeding assembly 30 clamps the film and feeds the film into the sealing point-cutting mechanism 40; the sealing and spot-cutting mechanism 40 seals and cuts the film to produce film bags connected together by a spot-cutting line.

Specifically, the first base plate 404 is fixed to the frame 10 of the bag making machine, the film passes over the first base plate 404, and then the sealing knife 401 seals the film and the spot-cutting knife 405 cuts the film. The seal knife 401 is connected with the beam 402 through the balance adjustment fixing component 403, and the beam 402, the seal knife 401 and the balance adjustment fixing component 403 are all located above the first bottom plate 404. The point breaking knife 405 is connected with the base 407 through the point breaking knife adjusting guide rod 406, the base 407 is located below the bottom plate, and the point breaking knife 405 is arranged on one side of the first bottom plate 404 in parallel. The transmission assembly 408 is connected to the cross beam 402 and the base 407, and the transmission assembly 408 is configured to provide a driving force and transmit the driving force to the cross beam 402 and the base 407, so as to drive the cross beam 402 and the base 407 to move up and down. The beam 402 moves up and down, and the sealing knife 401 is driven to move up and down by the balance adjustment fixing component 403; when the sealing knife 401 moves to the lowest position, the sealing knife 401 collides with the first bottom plate 404; since the film bag is above the bottom plate and below the sealing knife 401, the sealing knife 401 moves downward to seal the film bag; after sealing, the beam 402 moves upwards to drive the sealing knife 401 to move upwards, the film bag moves to enable the part to be sealed to move to the lower side of the sealing knife 401, and the sealing knife 401 moves downwards again to seal the film bag; the above operations are repeated. The base 407 moves up and down, and the point breaking knife 405 is driven to move up and down by the point breaking knife adjusting guide rod 406; the dotting knife 405 moves up and down to be higher or lower than the upper surface of the first base plate 404; when the dotting knife 405 moves upwards to the highest position, the dotting knife 405 is higher than the upper surface of the first bottom plate 404, and then the thin film bag is subjected to dotting cutting; after the point cutting, the base 407 moves downward to drive the point cutting knife 405 to move downward so that the point cutting knife 405 is lower than the upper surface of the first bottom plate 404; the film bag moves to enable the part to be cut by point to move to the position above the point cutting knife 405, and the point cutting knife 405 moves upwards again to cut the cut film bag by point; the above operations are repeated.

In the existing partial bag making machine, different mechanisms and processes are respectively arranged for sealing and point cutting, so that the bag making machine is large in size and high in manufacturing cost; still some bag machines, seal the sword and cut off the sword and be connected together fixedly, lie in the top of bottom plate simultaneously, drive simultaneously through drive arrangement and seal sword and cut off the sword up-and-down motion to accomplish simultaneously and seal and cut off the cutting work with some, but the difficult independent adjustment of this kind of structure seals the pressure of sword or cut off the sword a little, causes easily to seal the quality poor or cut off the quality poor with some. In the technical scheme, the sealing and spot-breaking mechanism 40 enables the sealing knife 401 and the spot-breaking knife 405 to be independent and not to affect each other by arranging the sealing knife 401 above the first bottom plate 404 and inversely arranging the spot-breaking knife 405 on one side of the first bottom plate 404, so that the pressure of the sealing knife 401 and the pressure of the spot-breaking knife 405 can be conveniently and independently adjusted, and the sealing and spot-breaking cutting quality can be further ensured. Generally, in order to ensure the effect of point cutting, the pressure of the point cutting knife should be set to be a little greater, if the point cutting knife and the sealing knife are connected and fixed, the pressure of the sealing knife is easily too great, and the sealing knife is easily damaged; in the technical scheme, the sealing cutter 401 and the point breaking cutter 405 are independent from each other, and the pressure of the sealing cutter 401 can be greatly reduced under the condition that the point breaking cutting effect is better, so that the service life of the sealing cutter 401 is prolonged.

More preferably, the sealing and spot-breaking mechanism 40 further includes a cloth seal fixing component 4012 for fixing cloth of the knife seal 401, and the cloth seal fixing component 4012 is disposed above the knife seal 401.

By adjusting the nut 4034, the screw 4031 can be adjusted to ascend or descend for a certain distance, and the seal cutter 401 is further driven to ascend or descend for a certain distance; when the sealing knife 401 is adjusted to ascend, namely, the pressure stroke is increased, the pressure of the sealing knife 401 acting on the first bottom plate 404 is reduced during sealing; when the sealing knife 401 is adjusted to descend, i.e. the pressure stroke is shortened, the pressure of the sealing knife 401 acting on the first bottom plate 404 is increased during sealing. The quality of the sealing line is ensured by adjusting the pressure to be proper.

The upper pipe positive block 4036 is sleeved on the screw 4031, the lower end of the spring 4035 abuts against the upper end of the lower pipe positive block 4037, and the upper end of the spring 4035 abuts against the lower end of the upper pipe positive block 4036. The rebound velocity of the spring 4035 is adjusted by adjusting the distance between the inner top surface of the adjustment block 4032 and the upper stem block 4036. The sealing knife 401 is in a vertical repeated motion during sealing, and after the sealing knife 401 collides with the first bottom plate 404, an upward acting force is applied to the first bottom plate and is further transmitted to the screw 4031 and the lower pipe positive block 4037; the screw 4031 and the lower stem 4037 move upward, compressing the spring 4035 and moving the upper stem 4036 upward.

The variable frequency motor 4081 runs, and the chain wheel 4089 and the chain drive the sealing knife main shaft 4082 to rotate; the sealing knife main shaft 4082 rotates, and the sealing knife guide rod 4083 is driven to move up and down repeatedly by the eccentric wheel 4088; the knife sealing guide 4083 is connected with the beam 402, so that the beam 402 is driven to move up and down repeatedly; the beam 402 drives the sealing knife 401 and the film pressing knife 409 to synchronously move up and down repeatedly, and sealing of the film bag is further achieved. On the other hand, the sealing knife main shaft 4082 rotates, so that the main shaft synchronous pulley 4084 sleeved on the sealing knife main shaft 4082 rotates synchronously; through the synchronous belt (in order to more clearly show the main shaft synchronous pulley 4084 and the point-breaking-cutter synchronous pulley 4085, the synchronous belt is not shown in the figure), the main shaft synchronous pulley 4084 drives the point-breaking-cutter synchronous pulley 4085 to synchronously rotate, and further drives the main shaft of the point-breaking cutter 405 to rotate; the eccentric shaft 4086 of the point breaking knife rotates to drive the guide rod 4087 of the point breaking knife to move up and down repeatedly; the dotting knife guide rod 4087 is connected with the base 407, so that the base 407 is driven to move up and down repeatedly; the base 407 drives the point-breaking knife 405 to move up and down repeatedly, so as to realize point-breaking cutting of the film bag.

In the existing sealing point-breaking mechanism, the point-breaking cutter and the sealing cutter are driven separately, so that synchronous operation is difficult to realize, and more driving devices are required to be used, so that the production cost is increased. In the technical scheme, the transmission assembly 408 is arranged, so that the variable frequency motor 4081 simultaneously provides power for the sealing knife 401, the point breaking knife 405 and the film pressing knife 409, and three steps of sealing, pressing a film bag and point breaking cutting are ensured to be synchronously performed, so that the production efficiency is improved; and driving devices are reduced, so that the production cost is reduced.

The thin film is coiled among the first film passing roller 201, the second film passing roller 202, the film passing plate 203, the third film passing roller 204 and the fourth film passing roller 205, so that the thin film also has a certain tension tendency in a loose state; the function of the supporting frame 207 is to prevent the two side parts of the film from being close to the middle in the transportation process to cause overlapping and creasing. The sealing and the cutting are discontinuous, so that the transfer of the film from the feeding device to said sealing and cutting mechanism 40 is also discontinuous, which causes the film to be always in a taut and loosely alternating condition, and therefore susceptible to creasing. Through making the film coil, this embodiment is provided with exhibition membrane module 20 can effectively avoid the film to produce pincher trees at the in-process that taut state and loose state constantly switched, but also can avoid the both sides of film to gather together towards the centre.
