DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model.

[0023] As Figures 1-4 The utility model discloses the material belt waste stripping device of the utility model can automatically remove the waste 02 attached on the material belt 01, and the material belt 01 is flattened by the shaping device 21, and the material belt 01 is collected by the winding device 22, and the secondary use of the material belt 01 is convenient.

[0024] The stripping device has a preliminary stripping assembly and a cleaning assembly located right below the preliminary stripping assembly. A gap is provided between the cleaning assembly and the preliminary stripping assembly for the feeding belt 01 to pass through. When the feeding belt 01 with waste 02 moves towards the cleaning assembly from the preliminary stripping assembly, the waste 02 on the feeding belt 01 is preliminarily separated from the waste 02 under the action of the preliminary stripping assembly (as shown in Figure 2 The waste 02 is separated from the feeding belt 01 through the cleaning assembly. The waste 02 on the feeding belt 01 is completely removed.

[0025] The preliminary stripping assembly includes a mounting plate 03 which is used to be mounted on a rotary knife die cutting machine or a rack. The preliminary stripping knife 04 is fixedly installed on the mounting plate 03 by integral molding or fasteners. The preliminary stripping knife 04 vertically extends downward. The feeding guide shaft 05 and the discharging guide shaft 06 are provided on both sides of the preliminary stripping knife 04. The feeding guide shaft 05 and the discharging guide shaft 06 are the same in structure and are rotatably installed on the mounting plate 03 through bearings. The preliminary stripping knife 04 is provided with a circular arc-shaped knife edge.

[0026] When the feeding belt 01 passes through the feeding guide shaft 05, the preliminary stripping knife 04 and the feeding guide shaft 05 in sequence, the feeding belt 01 is in a V shape. Since the knife edge of the preliminary stripping knife 04 is circular arc-shaped, extrusion force is generated when the waste 02 on the feeding belt 01 passes through the knife edge. The end of the waste 02 is forced to separate from the feeding belt 01 to form a gap 23. The preliminary separation effect of the waste 02 from the feeding belt 01 is achieved.

[0027] The cleaning assembly includes a support frame which is fixedly installed on the rotary knife die cutting machine or the rack. The support frame is provided with a knife holder. The cleaning knife 13 is rotatably installed in the knife holder. The driving component which adjusts the rotation angle of the cleaning knife 13 is symmetrically provided in the knife holder.

[0028] The support frame includes a support plate 07 which is located right below the mounting plate 03. The support plate 07 is provided with mounting holes. The support plate 07 is fixedly installed on the die cutting machine by penetrating the adjustment holes with fasteners. The connecting plate 08 is fixedly installed on the upper edge of the support plate 07 by welding. The connecting plate 08 is perpendicular to the support plate 07 and parallel to the mounting plate 03. The guide holes are provided on the four corners of the connecting plate 08. The guide shaft 09 is slidably arranged in the guide holes. The guide shaft 09 vertically extends upward. The end of the guide shaft 09 is fixedly connected with the knife holder by welding. At least one support rod 11 is threadedly connected to the bottom of the knife holder. Two support rods 11 are diagonally arranged on the bottom plate 10. The support rod 11 is a fastener. The end of the support rod 11 penetrates the knife holder and abuts against the connecting plate 08. The forward rotation or reverse rotation of the support rod 11 drives the knife holder to move up and down along the guide shaft 09. The guide rod ensures that the knife holder moves in a straight line during the movement.

[0029] The tool holder comprises a bottom plate 10 fixedly connected with the guide shaft, and two transition plates 12 arranged on both sides of the bottom plate 10, which are located on both sides of the mounting plate 03. A cleaning knife 13 is arranged between the two transition plates 12, and the two ends of the cleaning knife 13 are connected with the two transition plates 12 by micro bearings, so that the cleaning knife 13 rotates between the two transition plates 12. The driving component is arranged below the cleaning knife 13.

[0030] The driving component comprises a limiting plate 14 fixedly connected with the transition plate 12 by welding, and a limiting rod 15 threadedly connected with the limiting plate 14. The limiting rod 15 is a fastener, and can also be replaced by a gas cylinder or a lead screw. One end of the limiting rod 15 extends towards the cleaning knife 13 and is connected with the cleaning knife 13 by a micro universal joint 16.

[0031] In use, the cleaning knife 13 can be driven to rotate around the bearing by rotating the limiting rod 15. The included angle between the cleaning knife 13 and the preliminary stripping knife 04 is adjusted to adapt to the stripping of different waste materials 02.

[0032] As shown in Figure 2 If the hardness of the waste material 02 attached to the material belt 01 is higher than that of the material belt 01, such as when the waste material 02 is an aluminum product or other product, the end of the waste material 02 is easy to separate from the material belt 01 and form a gap when the waste material 02 passes through the preliminary stripping knife 04 due to the high hardness of the waste material 02. The cutting edge of the cleaning knife 13 penetrates into the gap. It is equivalent to applying a downward stripping force to the waste material 02 to separate the waste material 02 from the material belt 01.

[0033] As shown in Figure 3 On the contrary, if the hardness of the waste material 02 attached to the material belt 01 is close to that of the material belt 01, such as when the waste material 02 is a film or a plastic sheet, the end of the waste material 02 is difficult to separate from the material belt 01 or cannot be separated when the waste material 02 passes through the preliminary stripping knife 04. Thus, there is no gap between the waste material 02 and the material belt 01, or the opening degree of the gap is less than the thickness of the cutting edge of the cleaning knife 13. In this case, the included angle between the cleaning knife 13 and the preliminary stripping knife 04 needs to be adjusted to make the included angle between the cleaning knife 13 and the material belt 01 smaller to clean the waste material 02. When the waste material 02 on the material belt 01 contacts the cleaning knife 13, it is equivalent to the cleaning knife 13 shoveling the waste material 02 from the material belt 01. Therefore, the included angle between the cleaning knife 13 and the preliminary stripping knife 04 is changed by the driving component to clean the waste material 02 of different materials.

[0034] The square adjusting hole 17 is arranged in the base plate 10. The adjusting hole 17 is located directly below the transition plate 12. The bottom of the transition plate 12 is provided with an adjusting block 18 matched with the adjusting hole 17, and the two sides of the adjusting hole 17 are provided with locking rods 19 which are fasteners, and the locking rods 19 are threadedly connected to the transition plate 12 and abut against the two sides of the adjusting block 18.

[0035] In use, the locking rods 19 are loosened, and the operator pushes the adjusting block 18 to move in the adjusting groove. Thus, the transition plate 12 slides on the base plate 10. When the position of the transition plate 12 is determined, the locking rods 19 are rotated to abut against the two sides of the adjusting block 18, so as to fix the adjusting block 18 in the adjusting groove.

[0036] In order to prevent the adjusting block 18 from falling off from the adjusting hole 17, the upper and lower sides of the adjusting block 18 are provided with clamping grooves 20. The width of the clamping groove 20 is matched with the thickness of the base plate 10. Through the cooperation of the clamping groove 20 and the transition plate 12, the adjusting block 18 can move in the adjusting hole 17 while preventing the adjusting block 18 from falling off.

[0037] In use, when the waste 02 of the same material is in different thicknesses of the material belt 01, and the gap between the cleaning knife 13 and the preliminary stripping knife 04 needs to be adjusted, first, the locking rods 19 are loosened, and the operator pushes the adjusting block 18 to move in the adjusting groove. Thus, the transition plate 12 slides on the base plate 10. When the position of the transition plate 12 is determined (after the gap between the cleaning knife 13 and the preliminary stripping knife 04 is determined), the locking rods 19 are rotated to abut against the two sides of the adjusting block 18, so as to fix the adjusting block 18 in the adjusting groove. Thus, through the cooperation of the adjusting block 18, the adjusting hole 17 and the locking rods 19, the gap between the cleaning knife 13 and the preliminary stripping knife 04 in the horizontal direction is adjusted to meet the cleaning of the waste 02 on the material belt 01 of different thicknesses.

[0038] When the material belt 01 is of the same thickness, and the waste 02 on the material belt 01 is of different materials, the included angle between the cleaning knife 13 and the preliminary stripping knife 04 needs to be adjusted. First, the included angle between the cleaning knife 13 and the preliminary stripping knife 04 is adjusted through the cooperation of the limiting plate 14, the limiting plate 14 and the universal joint 16. The adjustment of the included angle is selected according to the actual situation. Since the included angle between the cleaning knife 13 and the preliminary stripping knife 04 is changed, the gap between the cleaning knife 13 and the preliminary stripping knife 04 is also changed. Then, the base plate 10 is driven to move up and down through the forward rotation and reverse rotation of the supporting rod 11, so as to adjust the distance between the cleaning knife 13 and the preliminary stripping knife 04 in the vertical direction. Then, the gap between the cleaning knife 13 and the preliminary stripping knife 04 in the horizontal direction is adjusted through the cooperation of the adjusting block 18, the adjusting hole 17 and the locking rods 19. Thus, the direct gap adjustment of the cleaning knife 13 and the preliminary stripping knife 04 is achieved.

[0039] It should be noted that, for the sake of clarity, the fastener described in the present application is any one of a screw, a bolt, a screw.

[0041] The above embodiments only describe the preferred embodiments of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements to the technical solutions of the present application made by ordinary engineering technicians in the field shall fall within the protection scope determined by the claims of the present application.
