Description

Technical Field

[0001] The utility model relates to the technical field of waste material removing devices, in particular to a sheet material hole-shaped waste material removing device. Background Art

[0002] During the production process, it is sometimes necessary to die-cut multiple openings on the sheet material strip. After the sheet material strip is separated from the base film, the porous waste generated at the openings will adhere to the sheet base film. In order to recycle the sheet base film, the porous waste on the sheet base film needs to be removed. Among them, the traditional way to remove the porous waste is to use other sticky films to stick them away. When using this method to discharge waste, additional films will be used, which will also cause material waste and increase production costs.

[0003] Therefore, a sheet material hole-shaped waste material removing device capable of solving the above-mentioned problems is needed. Utility Model Content

[0004] The utility model provides a device for removing hole-shaped waste materials of sheets, which uses a stripping knife and a high-speed rotating waste removing blade to adapt to each other, thereby realizing efficient removal of hole-shaped waste materials of sheets and reducing waste of sheet base films.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A device for removing porous waste from sheets comprises a waste removal shell with openings at both ends, a stripping knife is arranged inside the waste removal shell, the blade of the stripping knife is arranged downward, a waste removal mechanism for knocking the porous waste from the sheet base film is arranged below the stripping knife, a first winding roller and a second winding roller are respectively arranged on both sides of the stripping knife, the first winding roller and the second winding roller are both rotatably installed on the waste removal shell, and the sheet base film sequentially passes around the first winding roller, the stripping knife and the second winding roller.

[0007] As a preferred technical solution, an electrostatic eliminator is arranged below the first winding roller.

[0008] As a preferred technical solution, the waste removal mechanism includes a rotating shaft rotatably installed inside the waste removal shell, the rotating shaft is transmission-connected to a power member, the rotating shaft extends along the length direction of the stripping knife, a plurality of waste removal blades are evenly distributed on the peripheral wall of the rotating shaft, each of the waste removal blades extends along the circumference of the rotating shaft, the length of each of the waste removal blades is the same as the length of the rotating shaft, and the size of the gap between the waste removal blade and the stripping knife is adapted to the thickness of the sheet base film.

[0009] As a preferred technical solution, the waste removal shell includes two oppositely arranged side plates, and the two ends of the rotating shaft are rotatably installed on the corresponding side plates respectively, a protective cover is fixed on the outer wall of one of the side plates, the power member is fixedly installed in the protective cover, and a guard plate is commonly fixed between the two side plates, each of the guard plates extends along the axial direction of the rotating shaft, and an inwardly inclined anti-flying plate is provided at the upper end of one of the guard plates, and the anti-flying plate is arranged below the second winding roller.

[0010] As a preferred technical solution, a mounting seat is fixedly mounted on each of the two ends of the stripping knife, and the two mounting seats are mounted together on a connecting rod, and the two ends of the connecting rod are fixedly mounted on the corresponding side plates.

[0011] As a preferred technical solution, the first winding roller and the second winding roller are both rotatably mounted on a shaft, and both ends of each shaft are fixedly mounted on the corresponding side plate.

[0012] As a preferred technical solution, the power component adopts a pneumatic motor, the housing of the pneumatic motor is fixed in the protective cover, and the rotating shaft is fixedly installed on the motor shaft of the pneumatic motor.

[0013] As a preferred technical solution, the power member adopts an electric motor, the housing of the electric motor is fixed in the protective cover, and the rotating shaft is fixedly installed on the motor shaft of the electric motor.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0015] Since the sheet porous waste removing device includes a waste removing shell, a stripping knife and a waste removing mechanism, in the utility model, the sheet base film is arranged with the side with the sheet porous waste facing downward, so when the sheet base film passes around the blade of the stripping knife, the two ends of the sheet porous waste are separated from the sheet base film, and at the same time, the sheet porous waste is removed from the sheet base film by the waste removing mechanism, and the removed sheet porous waste is discharged through the opening at the bottom of the waste removing shell, and the sheet base film that completes the waste removal work continues to move forward and is finally rolled up for recycling.

[0016] Compared with the traditional waste removal method of using sticky tape film to pick up waste, the utility model does not need to use additional tape film to complete the removal of sheet porous waste, thereby avoiding the waste of additional tape film, and at the same time can thoroughly clean the sheet porous waste on the sheet base film, facilitating the subsequent recycling and reuse of the sheet base film, thereby solving the problem of the sheet base film being unable to be reused due to a large amount of waste attached to the sheet base film, thereby reducing the waste of the sheet base film and reducing the product input in the production process.

[0017] Since the waste removal mechanism includes a rotating shaft, a power member and a waste removal blade, in the utility model, the power member is used to drive the rotating shaft and the waste removal blade to rotate at a high speed, and the rotation direction thereof corresponds to the sheet base film. Therefore, the waste removal blade rotating at a high speed continuously strikes the raised porous waste of the sheet, sweeping the porous waste of the sheet off the sheet base film, thereby realizing efficient removal of the porous waste of the sheet.

[0018] Since an electrostatic eliminator is arranged below the first winding roller, in the utility model, the arrangement of the electrostatic eliminator plays a role in eliminating static electricity and preventing adhesion, thereby reducing the bonding strength between the porous waste of the sheet and the sheet base film. Therefore, while ensuring that the waste removal blades sweep the porous waste of the sheet off the sheet base film, the sheet base film will not be damaged, thereby ensuring the subsequent recycling and reuse of the sheet base film.

[0019] Since the waste removal shell includes side plates, guard plates and anti-flying plates, in the utility model, the anti-flying plates are arranged on the rear side of the waste removal blades, thereby preventing the swept sheet-shaped waste from escaping from the waste removal shell.

[0031] like Figure 3 and Figure 6 As shown together, an electrostatic eliminator 6 is arranged below the first winding roller 3. In the embodiment, the electrostatic eliminator 6 can adopt the ST-DC-507A-250 model of the STIKE electrostatic eliminator. At the same time, the setting of the electrostatic eliminator 6 plays a role in eliminating static electricity and preventing adhesion, reducing the adhesion strength between the sheet porous waste and the sheet bottom film 5, thereby ensuring that the waste removal blade 8 sweeps the sheet porous waste off the sheet bottom film 5 without causing damage to the sheet bottom film 5, thereby ensuring the subsequent recycling and reuse of the sheet bottom film 5.

[0032] like Figure 3 , Figure 6 and Figure 7 As shown together, the waste removal mechanism includes a rotating shaft 7 rotatably installed inside the waste removal shell 1, the rotating shaft 7 is transmission-connected to a power member, the rotating shaft 7 extends along the length direction of the stripping knife 2, and a plurality of waste removal blades 8 are evenly distributed on the peripheral wall of the rotating shaft 7, each waste removal blade 8 extends along the circumference of the rotating shaft 7, the length of each waste removal blade 8 is the same as the length of the rotating shaft 7, and the size of the gap between the waste removal blade 8 and the stripping knife 2 is adapted to the thickness of the sheet base film 5.

[0033] Compared with the traditional waste removal method of using sticky material tape film to pick up waste, the utility model uses the waste removal blades 8 rotating at high speed to sweep the sheet porous waste from the sheet base film 5, and the sheet porous waste can be removed without using additional material tape film, thereby avoiding the waste of additional material tape film, and at the same time, the sheet porous waste on the sheet base film 5 can be thoroughly cleaned, which is convenient for the subsequent recycling and reuse of the sheet base film 5, thereby solving the problem that the sheet base film 5 cannot be reused due to a large amount of waste attached to it, thereby reducing the waste of the sheet base film 5 and reducing the product input in the production process.

[0034] like Figure 1-Figure 7 As shown together, the waste removal shell 1 includes two oppositely arranged side plates 9, and the two ends of the rotating shaft 7 are rotatably installed on the corresponding side plates 9, wherein a protective cover 10 is fixed on the outer wall of one side plate 9, and the power member is fixedly installed in the protective cover 10, and a guard plate 11 is fixed between the two side plates 9, and each guard plate 11 extends along the axial direction of the rotating shaft 7, and the upper end portion of one of the guard plates 11 is provided with an inwardly inclined anti-flying skew plate 12, and the anti-flying skew plate 12 is arranged below the second winding roller 4.

When the sheet base film 5 passes around the first winding roller 3 and the second winding roller 4, it drives the first winding roller 3 and the second winding roller 4 to rotate. In addition, in the present embodiment, the outer peripheral surfaces of the first winding roller 3 and the second winding roller 4 are surface treated, and the surfaces are sprayed with an anti-stick coating. Therefore, neither the sheet base film 5 nor the sheet porous waste will adhere to the first winding roller 3 and the second winding roller 4, thereby ensuring the smooth progress of waste removal and base film recovery.
