Description

Technical Field

[0001] The utility model relates to the technical field of longitudinal cutting machines, in particular to a longitudinal cutting machine with an adsorption function. Background Art

[0002] As an important part of the slitting machine, the cutting machine is often used to perform cutting operations. The cutting machine consists of a blade, a driving device, and a paper guide device. Its function is to cut the cardboard before it enters the slitting machine when changing orders, which is conducive to timely knife arrangement and positioning of the slitting machine.

[0003] When the cardboard is being slitting, the cardboard is placed on the conveying device of the slitting machine. The conveying device conveys the cardboard to the bottom of the circular cutter for slitting into strips. When the cardboard needs to be changed, the cutting machine is started to cut off the tail end of the cardboard to replace the cardboard.

[0004] However, during the cardboard change process, the cardboard is cut, which causes the force on the cardboard at the cutting point to change, causing the cardboard to fly up, bend and swing its tail, resulting in the position of the tail cardboard to shift, affecting the slitting accuracy and causing uneven slitting.

[0005] In view of this, we propose a longitudinal cutting machine with adsorption function. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] When the cardboard is being slitting, the cardboard is placed on the conveying device of the slitting machine. The conveying device conveys the cardboard to the bottom of the circular cutter for slitting into strips. When the cardboard needs to be changed, the cutting machine is started to cut off the tail end of the cardboard to replace the cardboard.

[0021] During the cardboard change process, the cardboard is suddenly cut off, which causes the force at the cut point of the cardboard to change. The cardboard cut point is no longer subjected to the force, which leads to unbalanced force, causing the cardboard cut point to fly up and bend. The tail swinging will cause the cardboard to deflect and bend, which will cause the position of the cardboard cut point to shift, affecting the slitting accuracy and resulting in uneven slitting.

[0022] The utility model provides a longitudinal cutting machine with an adsorption function, such as Figures 1 to 4 As shown, it includes a slitting machine body 1, a cutting device 2, a knife holder 3, a cutting knife 4, an adjusting component 5 and a bellows 6; the slitting machine body 1 is provided with a cutting device 2 at one end, and the cutting device 2 is used to cut the cardboard when the cardboard roll is changed. The cutting device 2 is provided with a driving chamber 21 and a rotating chamber 22, and the driving chamber 21 is communicated with the rotating chamber 22. The knife holder 3 is located below the driving chamber 21, and the cutting knife 4 is fixedly connected to the knife holder 3. The adjusting component 5 is installed in the driving chamber 21, and the adjusting component 5 is connected to the bellows 6. The bellows 6 is located in the rotating chamber 22. The bellows 6 makes the cardboard close to the slitting machine body 1 by blowing out air, so as to avoid the cardboard from flying up and bending when being cut;

[0023] The bellows 6 is composed of a shell 61 and a fan 62. The shell 61 is rotatably connected to the cutting device 2. The shell 61 has a linear array of fans 62. The shell 61 is provided with an air outlet 611. The air outlet 611 corresponds to the position of the fan 62. The air outlet 611 is cylindrical 612. The cylindrical air outlet 611 has a gathering effect on the exhausted air, thereby increasing the exhaust volume and further increasing the force of the bellows 6 on the cardboard, so that the cardboard fits the cardboard of the slitting machine more closely. The fan blades 621 of the fan 62 are spiral 622, the fan blades 621 of the spiral 622 enhance the disturbance effect on the air, which is beneficial to increasing the exhaust volume of the fan 62. The fan blades 621 are arranged in a staggered manner, which is helpful to increase the fan blade coverage area in a limited space, enhance the concentration of wind flow, and thus improve the exhaust effect. When the knife holder 3 drives the cutting knife 4 to cut the cardboard, the knife holder 3 drives the bellows 6 to rotate through the adjustment component 5. The bellows 6 rotates so that the wind it blows is always aimed at the cut end of the cardboard, so that the cardboard is always close to the longitudinal cutting machine body 1, and the cardboard is prevented from being offset during the transportation process.

An inclined groove is provided at the top of the push rod 51. The spur rack 52 is located in the driving chamber 21. An inclined groove that cooperates with the push rod 51 is provided at one end of the spur rack 52. The mutual cooperation of the inclined grooves converts the numerical movement of the push rod 51 into horizontal sliding of the spur rack 52. A reset spring 53 is provided between the other end of the spur rack 52 and the driving chamber 21. When the spur rack 52 is no longer subjected to the extrusion force of the push plate, the reset spring 53 pushes the spur rack 52 to reset. The wheel set 54 includes a driving wheel 541 and a driven wheel 542; the driving wheel 541 is meshed with the spur rack 52, and the driven wheel 542 is connected to the bellows 6. When the knife holder 3 moves upward, the push plate pushes the spur rack 52 to slide horizontally, and the spur rack 52 drives the driving wheel 541 to rotate, and the driving wheel 541 drives the driven wheel 542, and the driven wheel 542 drives the bellows 6 to deflect along the direction of the longitudinal cutter body 1, so that the bellows 6 is always aligned with the cardboard cutting position. When the knife holder 3 moves downward, the push plate no longer pushes the spur rack 52, and the spur rack 52 is reset under the action of the reset spring 53, and the spur rack 52 drives the driving wheel 541 to reverse, and the driving wheel 541 drives the driven wheel 542 to reverse, thereby driving the bellows 6 to reset.

[0026] In this embodiment, when the slitting machine needs to change orders, the staff starts the driving device and the bellows 6, the driving device pushes the knife holder 3 to move downward, the knife holder 3 drives the cutting knife 4 to move synchronously to cut the cardboard, and when the knife holder 3 resets and moves upward, the push rod 51 on the knife holder 3 pushes the spur rack 52 to slide along the direction of the slitting machine body 1 through the inclined groove, the spur rack 52 squeezes the reset spring 53 to contract, the spur rack 52 drives the spur gear set 54 to rotate, and the spur gear set 54 drives the bellows 6 to deflect, so that the air outlet 611 of the bellows 6 is always aligned with the cardboard cutting position, so that the cardboard remains stable. When the cardboard cutting is completed, the driving device and the bellows 6 are closed;

[0027] When the slitting machine needs to change orders again, the knife holder 3 moves downward, and the push plate no longer pushes the spur rack 52 to move. The spur rack 52 is reset under the action of the reset spring 53, and the spur rack 52 is engaged with the spur gear set 54 to drive the spur gear set 54 to rotate.
