It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0032] like Figures 1 to 13 As shown, the utility model provides a sheet slitting machine, including a support body 1, on which a feeding assembly 2, a cutting assembly 4, a separation assembly 5 and a waste assembly 6 are sequentially arranged, the feeding assembly 2 is used to place the masterbatch, the cutting assembly 4 is used to cut the finished product, the separation assembly 5 is used to separate the finished product from the masterbatch, and the waste assembly 6 is used to collect the waste separated from the finished product;

[0033] The separation component 5 includes a grid roller 50, a grid drive 51, an air pump 53 and an air duct 52. The air pump 53 is installed on the bracket body 1. The grid roller 50 is installed on the bracket body 1 through a rotating seat. A cavity is provided in the grid roller 50. The air duct 52 is used to transport the high-pressure airflow output by the air pump 53 to the cavity. The air duct 52 extends into the cavity and a plurality of nozzles 54 are provided at the position where the air duct 52 is located in the cavity; the grid drive 51 is used to drive the grid roller 50 to rotate.

[0034] In this embodiment, a section of the air guide 52 is provided with a nozzle 54 which is installed in the grid roller 50 through a bearing, ensuring that the nozzle 54 is always in the same direction when the grid roller 50 rotates. The high-pressure airflow ejected from the nozzle 54 can apply pressure to the finished product on the masterbatch, causing the finished product to fall off from the masterbatch, and the high-pressure airflow can prevent the separation component 5 from directly contacting the finished product, thereby preventing the separation component 5 from damaging the finished product during high-speed transmission.

[0035] In this embodiment, the cutting assembly 4 includes a support roller 41 and a tool roller 40, both of which are installed on the bracket body 1 through a support 43, and multiple groups of detachable cutting tools 42 are installed on the tool roller 40; a distance adjustment knob 44 is provided on the tool roller 40, and the distance adjustment knob 44 is used to adjust the distance between the tool roller 40 and the support roller 41.

[0036] Through the above design, the staff can replace different cutting tools 42 according to the needs. When in use, the cutting tool 42 is fixed on the tool roller 40, and then the distance adjustment knob 44 is simply turned to make the cutting tool 42 close to the support roller 41. When the mother material passes between the cutting tool 42 and the support roller 41, the rotating tool roller 40 can drive the cutting tool 42 to cut the mother material.

[0037] In this embodiment, the feeding assembly 2 includes a masterbatch seat 21 and a guide roller 20; the guide roller 20 is installed on the bracket body 1 through the guide seat 27, and a buffer elastic member 26 is installed between the guide roller 20 and the guide seat 27; the masterbatch seat 21 is installed on the bracket body 1, and the masterbatch seat 21 can slide on the bracket body 1, and a material trough for placing the masterbatch is provided on the masterbatch seat 21.

[0038] In this embodiment, a support bearing 23 and a flap 22 are provided at the material trough.

A plurality of groups of limiting optical axes 24 are provided at the bottom of the masterbatch seat 21, and a limiting elastic member 25 is sleeved on the limiting optical axis 24.

[0039] Through the above-mentioned design scheme, the masterbatch seat 21 can slide back and forth during the loading process, so as to reduce the vibration of the masterbatch during the loading process. The limiting elastic member 25 arranged at the bottom of the masterbatch seat 21 can limit the masterbatch seat 21 on the bracket body 1; when the masterbatch needs to be loaded, the staff only needs to open the flap 22, take out the processed masterbatch, put the complete masterbatch into the material trough, and then cover the flap 22 to prevent the masterbatch from jumping out of the material trough during processing. In this embodiment, a handle and a locking knob are provided on the flap 22, a threaded end is provided on the locking knob, and a threaded hole is provided on the masterbatch seat 21. When locking, the staff can turn the locking knob to lock the flap 22 on the masterbatch seat 21.

The tensioning assembly 3 includes a balance wheel 33, a swing arm 32, a support rod 31 and a tensioning elastic member 30; the support rod 31 is installed on the bracket body 1, the swing arm 32 is hinged on the support rod 31, and the balance wheel 33 is installed on the swing arm 32; one end of the tensioning elastic member 30 is installed on the support rod 31, and the other end is installed on the end of the swing arm 32 away from the balance wheel 33.

[0041] Through the above design, the tensioning assembly 3 can adjust the tension of the masterbatch during the transmission process. Under normal circumstances, the gravity of the balance wheel 33 and the tension of the tensioning elastic member 30 are balanced. When conveying the masterbatch, the balance wheel 33 will swing upward for a distance under the tension of the masterbatch until it reaches a balanced state. When the masterbatch is loose, the balance wheel 33 swings downward under the action of gravity to extend the stroke of the masterbatch, ensuring that the masterbatch in transmission can be in a tensioned state; when the masterbatch is over-tightened, the balance wheel 33 is driven upward by the masterbatch to reduce the stroke distance of the masterbatch and avoid damage to the masterbatch due to over-tightening. When the masterbatch in the feeding assembly 2 is exhausted, one end of the masterbatch in transmission loses tension, and the balance wheel 33 without restriction will swing downward under the action of gravity, while the tensioning elastic member 30 can apply tension to the swing arm 32 to avoid damage to the balance wheel 33.

[0042] In this embodiment, a discharging conveyor belt 8 is provided below the separation assembly 5 , and the discharging conveyor belt 8 is used to convey the separated finished products to a material frame 9 for collecting the finished products.

The feeding components 7 include a feeding drive shaft 71, an adjusting wheel 72, a pressure block 74, an adjusting elastic member 73, a feeding rack 70 and an adjusting knob 75. The feeding drive shaft 71 and the adjusting wheel 72 are both mounted on the feeding rack 70. The feeding rack 70 is mounted on the bracket body 1. The adjusting knob 75 is mounted on the feeding rack 70. The adjusting knob 75 is used to drive the pressure block 74 to move closer to or away from the adjusting wheel 72. The adjusting elastic member 73 is sleeved on the adjusting knob 75, and one end of the adjusting elastic member 73 is against the adjusting wheel 72, and the other end is against the pressure block 74.

[0044] In this embodiment, a feeding assembly 7 is provided between the feeding assembly 2 and the tensioning assembly 3 , and between the tensioning assembly 3 and the cutting assembly 4 .

[0045] Through the above-mentioned design scheme, the auxiliary roller 10 is used to adjust and balance the transmission of the masterbatch to prevent the bracket body 1 from interfering with the masterbatch; the feeding assembly 7 can provide tension for the transmission process of the masterbatch, balance the tension borne by the masterbatch at different stages, and prevent the masterbatch from being damaged. In this embodiment, a feeding rack 70 is provided on both sides of the feeding drive shaft 71 and the adjusting wheel 72, and the adjusting knobs 75 on both sides are connected to the synchronous pulley through a synchronous belt. By rotating the adjusting knob 75 on one side, the adjusting knob 75 on the other side can be rotated together to achieve the purpose of synchronously adjusting the pressure block 74; when the pressure block 74 is close to the adjusting wheel 72, the adjusting elastic member 73 is compressed, and the adjusting wheel 72 is pressed toward the feeding drive shaft 71, ensuring that the masterbatch can be driven by the feeding drive shaft 71.

In this embodiment, a transmission belt and a transmission wheel are provided in the connecting seat, and the roller driving member 60 drives the collecting roller 65 to rotate on the roller seat 64 through the transmission belt and the transmission wheel, so as to curl the waste onto the collecting roller 65.

[0047] Through the above design scheme, the waste materials separated from the finished products by the separation component 5 will pass through the detection roller 61, and the detector 63 will detect the waste materials passing through the detection roller 61 to detect whether there are any unseparated finished products left on the waste materials. If it is detected that there are too many finished products left on the waste materials, the detector 63 will sound an alarm to remind the staff to come for inspection; the collection roller 65 rotates under the drive of the roller driving member 60 to collect the waste materials onto the collection roller 65; the shearing part is used to shear the waste materials.
