Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to a waste discharging fixture used in cooperation with a die-cutting machine. Background Technique

[0002] When punching and cutting relatively thick materials such as foam, if there are holes in the middle of the product, the hardware die cannot discharge the waste of punching and cutting. Since it is necessary to punch and cut into coiled materials, therefore, the inner hole waste of this punching and cutting needs to be manually cleaned. Due to the low efficiency of manual cleaning, it directly affects the production efficiency; if the coiled materials for manual waste discharging are placed for a long time, the colloid will stick back and be difficult to clean. Moreover, manual contact and waste discharging will also reduce the product quality.

[0003] Therefore, we propose a waste discharging fixture used in cooperation with a die-cutting machine. Content of the Utility Model

A return spring 14 located inside the air suction box 12 is sleeved outside the pulling rope 5. By providing the pulling rope 5, when the die cutting head 1 moves downward for die cutting, the pulling rope 5 relaxes, and under the action of the return spring 14, the two piston plates 13 move closer to each other, enabling the second one-way valve 18 to conduct, discharging the air inside the air suction box 12, facilitating the next waste material suction. A connecting hose 15 located between the two piston plates 13 is fixedly installed at the bottom of the air suction box 12. An exhaust pipe 17 located on one side of the connecting hose 15 is provided at the bottom of the air suction box 12.

A second one-way valve 18 is provided at the connection between the exhaust pipe 17 and the air suction box 12. The other end of the connecting hose 15 is fixedly installed with the bottom of the material storage groove 9. By providing the air suction box 12, when the strip of material after the die cutting head 1 finishes punching moves above the backing plate 7, the waste material coincides with the material suction port 8. As the die cutting head 1 rises, the pulling rope 5 pulls the two piston plates 13 away from each other. At the same time, the first one-way valve 16 conducts, enabling the connecting hose 15 to suck air from the material storage groove 9, thereby generating negative pressure at the material suction port 8, causing the waste material to enter the material storage groove 9 under the action of air pressure through the material suction port 8. The air suction box 12 cooperates with the die cutting head 1 for punching, and the waste discharging speed is the same as the punching speed, that is, discharging immediately without pausing.

[0022] A buffer frame 20 is fixedly installed in the middle inside the air suction box 12. The buffer frame 20 is located between the two piston plates 13. The connections of the connecting hose 15 and the exhaust pipe 17 with the air suction box 12 are located directly below the buffer frame 20. The material of the buffer frame 20 is shock-absorbing rubber. The shape of the buffer frame 20 is an inverted concave shape. The pulling rope 5 penetrates through the front and back sides of the air suction box 12. Deflection rollers 19 are provided on the front and back sides of the air suction box 12. The pulling rope 5 is in rolling connection with the deflection rollers 19.

[0023] The fixed plate 2 is provided with an empty slot located between a plurality of fixing pins, and the material storage slot 9 passes through the empty slot to the bottom of the fixed plate 2. The pad plate 7 is provided with a through hole corresponding to the fixing pin. The height of the pad plate 7 is the same as the height of the die-cutting seat 3. A base plate 10 fixed by a snap is provided at the bottom of the material storage slot 9. A rubber sealing ring is provided between the base plate 10 and the material storage slot 9. A quick connector 11 is provided in the middle of the base plate 10. The quick connector 11 and the other end of the connecting hose 15 are fixedly installed.

The protective net 21 is made of a steel wire mesh with an aperture less than five millimeters. The pad plate 7 is fixed by a fixing pin, so that the pad plate 7 can be replaced according to the distance and size of the opening of the material belt. The pad plate 7 with a suitable suction port 8 can be quickly connected with the connecting hose 15 in conjunction with the quick interface.

[0024] Working principle:

[0025] When the material strip after punching by the die-cutting head 1 moves to the top of the pad 7, the waste material overlaps with the suction port 8. As the die-cutting head 1 rises, the pull rope 5 pulls the two piston plates 13 away from each other. At the same time, the first one-way valve 16 is turned on, so that the connecting hose 15 sucks air from the storage tank 9 and generates negative pressure at the suction port 8, so that the waste material enters the storage tank 9 through the suction port 8 under the action of air pressure. The suction box 12 cooperates with the punching die-cutting head 1, and the waste discharge speed is the same as the punching speed, that is, When the die-cutting head 1 moves down for die-cutting, the pull rope 5 is loosened, and the two piston plates 13 are moved toward the middle under the action of the reset spring 14, so that the second one-way valve 18 is connected, and the air inside the suction box 12 is discharged, so as to facilitate the next waste suction. The pad 7 is fixed by the fixing pin, so that the pad 7 can be replaced according to the distance and size of the opening of the material belt. The pad 7 of the suitable suction port 8 can be quickly connected with the quick interface and the connecting hose 15.
