Description

Technical Field

[0001] The present application relates to the technical field of carton processing, and in particular to a waste cleaning device for carton processing. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., and there are various specifications and models. Cartons play an important role in modern logistics and packaging. They not only protect goods from damage, but also improve the display effect of goods and consumers' purchasing desire. Therefore, in the production and use of cartons, it is necessary to pay attention to issues such as quality, safety and environmental protection to ensure that cartons can meet various needs and play the greatest role.

[0003] Conventionally, cartons are folded from cut cardboard. During the carton processing, it is necessary to die-cut the edge positions on both sides of the cardboard according to the structure of the carton forming, so that multiple foldable board edges are formed on both sides of the cardboard, and then the cardboard is sent to the subsequent folding device to fold the cardboard to form a carton.

[0004] However, during the die-cutting process, paper scraps, paper strips and other waste materials will be formed, and the waste materials are easy to remain on the paperboard, resulting in waste materials inside the carton after the cardboard is folded to form a carton, thereby affecting the quality of the carton automated processing.

[0005] Therefore, there is an urgent need for a device that can clean up waste materials after cardboard die-cutting. Summary of the invention

[0006] The present application provides a waste cleaning device for carton processing, which can effectively clean the waste generated by cardboard die-cutting, thereby effectively ensuring the quality of the carton obtained by subsequent cardboard folding and forming.

[0007] The present application provides a waste cleaning device for carton processing, which adopts the following technical solution:

[0008] A waste cleaning device for carton processing is arranged based on a transport device and is located on a side of a die-cutting device close to the transport device, comprising two blowing components, two cleaning components and a collecting component;

[0009] The transport device comprises a frame and two transport components, the two transport components are respectively arranged on both sides of the frame; the transport component comprises two transport belts that can move relative to the frame, and a transport channel for transporting cardboard is provided between the two transport belts, and when the cardboard is transported, the foldable board edges of the cardboard are in contact with the two transport belts at the same time; the transport component has a clearance space communicating with the transport channel above the position of the transport channel near the entrance end, and two baffles are arranged on the frame, the two baffles correspond to the two clearance spaces one by one, and the baffle is located on the side of the corresponding clearance space away from the other clearance space;

[0010] The two blowing components and the two cleaning components correspond to the two transport components one by one respectively;

[0011] The blowing assembly includes a fan and a blowing pipe; the fan is arranged above the corresponding transport assembly, one end of the blowing pipe is connected to the fan, and the other end of the blowing pipe is located above the clearance space and the blowing direction is toward the clearance space;

[0012] The cleaning assembly comprises an elastic cleaning brush, which is located in the clearance space and above the transport channel, and one end of the air blowing tube close to the clearance space is located on a side of the cleaning brush close to the die-cutting device; when the paperboard is transported along the transport channel, the cleaning brush contacts and abuts against the edge of the paperboard;

[0013] The collecting component comprises a waste collecting part, and the waste collecting part is arranged below the transporting component and located between the two transporting components.

[0014] By adopting the above technical scheme, after the cardboard die-cutting is completed, it is sent to the transportation channel and transported by the transportation device. During the transportation, the blowing component first blows away the waste, and the waste that is not blown away is then removed by the cleaning brush. The blown away and removed waste will leave the cardboard and fall onto the waste collecting part below after the cardboard is transported away, completing the collection of the waste; the waste generated by the cardboard die-cutting can be effectively cleaned, thereby effectively ensuring the quality of the carton obtained by the subsequent cardboard folding and forming.

[0015] Optionally, the length direction of the cleaning brush is inclined relative to the transport direction of the cardboard, and the two cleaning brushes are in a constricted shape along the transport direction of the cardboard.

[0016] By adopting the above technical solution, the waste that is blown away but not blown away and the waste that is cleaned can be intercepted by the cleaning brush and moved along the inclined direction of the cleaning brush toward the center of the cardboard, so that the waste is kept away from the foldable edge of the cardboard, which is convenient for waste collection and reduces the probability of waste getting stuck and staying on the edge of the cardboard, thereby further improving the effect of waste cleaning.

[0017] Optionally, the length direction of the cleaning brush is inclined relative to the thickness direction of the cardboard, and the two cleaning brushes are tapered downward.

[0018] By adopting the above technical solution, the friction between the cleaning brush and the edge of the board can be smaller and the friction with the position close to the center of the cardboard can be larger, thereby reducing the probability of the cleaning brush causing damage to the edge of the board when cleaning waste, and at the same time can further improve the effect of the cleaning brush in intercepting waste and guiding the waste to move toward the center of the cardboard.

[0019] Optionally, the cleaning assembly further comprises a support frame, one end of which is connected to the frame body; the cleaning brush is connected end to end and is wound around the other end of the support frame.

[0020] By adopting the above technical solution, when the cleaning brush is cleaning the waste materials on the edge of the board, the waste materials will be cleaned by two rows of bristles, which can further improve the cleaning effect of the cleaning brush on the waste materials.

[0021] Optionally, the cleaning brush can be movably connected to the support frame along its own winding trajectory, and the plane where the cleaning brush winding trajectory is located is inclined relative to the transportation direction of the cardboard and is inclined upward along the transportation direction of the cardboard.

[0022] By adopting the above technical solution, during the transportation of cardboard, the cleaning brush can be driven to move relative to the support frame. During the movement of the cleaning brush, the cleaned waste can be driven to move toward the center of the cardboard, thereby further improving the cleaning effect of the cleaning brush on the waste.

[0023] Optionally, one end of the air blowing pipe close to the clearance space is tapered toward the direction close to the clearance space.

[0024] By adopting the above technical solution, the wind force of the gas blown out by the blowing pipe can be increased, thereby further improving the effect of blowing away the waste.

[0025] Optionally, the opening of the blowing pipe at one end close to the clearance space extends and expands toward the direction close to the other clearance space.

[0026] By adopting the above technical solution, the gas blown out from the extended and expanded opening of the air blowing pipe can facilitate the waste located near the center of the paperboard to fall onto the waste collecting piece for collection.

[0027] Optionally, the extension and expansion direction of the opening of the blow tube near one end of the clearance space is inclined relative to the transport direction of the cardboard and along the transport direction of the cardboard toward another blow tube, and the blowing direction of the blow tube at its own extension and expansion position is inclined downward toward the direction close to the die-cutting device.

[0028] By adopting the above technical solution, the gas blown out from the expanded opening of the air blowing pipe can further concentrate the waste on the cardboard toward the center position, and when blowing the waste off, it can also drive the waste to fall from a more central position, further facilitating the waste to fall onto the waste collecting piece.

[0029] Optionally, the collecting assembly further comprises a driving member and a plurality of driving rollers; the driving roller is rotatably connected to the frame, and the driving member can drive one of the driving rollers to rotate; the waste collecting member is connected end to end and is flexible, a plurality of grooves are provided on the outer surface of the waste collecting member, and the waste collecting member is simultaneously wound around a plurality of the driving rollers.

[0030] By adopting the above technical solution, waste materials that have fallen onto the waste collecting piece can be easily retained, and at the same time, after the waste collecting piece moves, waste materials collected on the waste collecting piece can be easily dumped and concentrated, so as to facilitate subsequent treatment of the waste materials.

[0031] Optionally, the baffle has a guide surface on one side close to the makeshift space, the position of the guide surface close to one end of the makeshift space is not lower than the position of the transport channel, and the guide surface can guide the gas in the makeshift space to move towards the direction close to the other makeshift space.

[0032] By adopting the above technical solution, the gas blown out of the blowing pipe can move along the guide surface after contacting the baffle, thereby further facilitating the gas to blow away the waste and drive the waste to move toward the center of the paperboard.

[0033] In summary, the present application includes at least one of the following beneficial effects:

[0034] 1. It can effectively clean up the waste generated by cardboard die-cutting, thereby effectively ensuring the quality of the cartons obtained by subsequent cardboard folding;

[0035] 2. It can facilitate the waste to be cleaned to leave the edge of the board, reduce the probability of waste getting stuck on the edge of the board, and increase the probability of waste falling and being collected after being transported away from the cardboard;

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-5 This application is described in further detail.

[0044] Embodiment 1:

[0045] Reference Figure 1 The embodiment of the present application discloses a waste cleaning device for carton processing, which can clean the waste generated by die-cutting the cardboard to form a foldable board edge when the cardboard is fed into the transportation device 2 after die-cutting, so that the waste is collected and processed after leaving the cardboard, thereby effectively ensuring the quality of the carton obtained by subsequent cardboard folding.

[0046] Reference Figure 1 and Figure 2 The waste cleaning device is installed based on the transport device 2, the transport device 2 is located on one side of the die-cutting device 1, and the waste cleaning device is located at a position of the transport device 2 close to the die-cutting device 1; after the cardboard is die-cut, it can be sent to the transport device 2 in a horizontal direction, and then the transport device 2 continues to transport the cardboard in a horizontal direction. In this embodiment, since the die-cutting device 1 is a prior art in the field, it will not be described in detail here, and it is only briefly shown in the drawings.

[0047] The transport device 2 includes a frame 21 and two transport components 22. The frame 21 is used to install the transport components 22, and the two transport components 22 are respectively installed on both sides of the width direction of the frame 21. The two transport components 22 are symmetrically distributed on the frame 21 and aligned along the width direction of the frame 21. The cardboard will be transported in a horizontal position along the length direction of the frame 21 under the action of the two transport components 22. During the transportation of the cardboard, the foldable board edges on both sides formed by die cutting will be transported on the two transport components 22 respectively, so as to realize the transportation of the entire cardboard, and multiple cardboards will be continuously transported at a certain distance during the transportation process.

[0048] The transport device 2 includes a plurality of transport rollers 222 and two transport belts 221. The transport rollers 222 are used to drive the transport belts 221 to move; and the transport belts 221 are used to drive the paperboard to move after contacting the edge of the paperboard.

[0049] The transport roller 222 is a cylindrical structure as a whole, and is rotatably connected to the frame 21. The rotation axis of the transport roller 222 coincides with its own axis and is parallel to the width direction of the frame 21. The transport belt 221 is a flexible belt-like structure connected end to end. Two transport belts 221 are respectively wound around and installed on multiple transport rollers 222, so that a transport channel 3 for transporting cardboard is formed between the two transport belts 221. During the transportation of cardboard, the edges of the cardboard on both sides will contact and abut against the upper and lower transport belts 221 in the corresponding transport channel 3, and the cardboard is transported and moved along the transport channel 3 through the movement of the transport belt 221. In this embodiment, for the convenience of the drawings, only a part of the transport device 2 is shown in the drawings.

[0050] Reference Figure 1 and Figure 3 In order to facilitate the feeding of the edge of the die-cut cardboard into the transport channel 3, it is preferred that in the transport component 22, the conveyor belt 221 located below extends a certain distance toward the die-cutting device 1 relative to the conveyor belt 221 above it, and a clearance space 4 communicating with the transport channel 3 is formed above it, and guide rollers 211 are rotatably connected in the two clearance spaces 4 on the frame 21.

[0051] The guide roller 211 is a cylindrical structure as a whole, installed in the clearance space 4 away from the conveyor belt 221 located above, and is rotatably connected to the frame 21. Its rotation axis coincides with its own axis and is parallel to the width direction of the frame 21.

[0052] The distance between the guide roller 211 and the conveyor belt 221 below is greater than the thickness of the cardboard. When the cardboard is die-cut and sent out to move toward the conveying device 2, the end of the edge of the cardboard contacts the lower half of the guide roller 211 and passes through the space between the guide roller 211 and the conveyor belt 221 below under the guidance of the guide roller 211, enters the clearance space 4, and then enters the conveying channel 3. The guide roller 211 can rotate relative to the frame 21 during the guiding process to reduce damage to the edge of the cardboard.

[0053] Reference Figure 1 and Figure 2 In order to further facilitate the feeding of the edge of the die-cut cardboard into the transport channel 3, it is preferred that the frame 21 has two guide plates 212 at one end close to the die-cutting device 1. The two guide plates 212 correspond one-to-one to the two transport components 22 and are located on the side of the corresponding conveyor belt 221 located below close to the die-cutting device 1.

[0054] The guide plate 212 is an arc-shaped plate structure as a whole. One end of the arc-shaped track of the guide plate 212 is fixedly connected to the frame 21 and is flush with the top surface of the conveyor belt 221 located below along the direction of the conveying channel 3. The other end is located on the side of the conveying component 22 close to the die-cutting device 1 and is located lower than the top surface of the conveyor belt 221 located below, and the arc-shaped opening of the guide plate 212 faces downward.

[0055] At this time, when the cardboard is die-cut and sent out to move toward the transportation device 2, the end of the edge of the cardboard will contact the arc-shaped convex surface of the guide plate 212, and then, under the guidance of the arc-shaped convex surface, its end will be sent into the transportation channel 3 in a state of being in contact with the surface of the conveyor belt 221 located below.

[0056] In this embodiment, since the transport device 2 with the above-mentioned functions is a common prior art, it will not be described in detail here (its driving structure will not be introduced here either), and it is only briefly represented in the accompanying drawings (only part of the transport rollers 222 and the transport belt 221 are shown, and the related driving structure is omitted).

[0057] Reference Figure 2 and Figure 3 The waste cleaning device includes two blowing components 5, two cleaning components 6 and a collecting component 7. The blowing component 5 is used to blow away the waste formed after the cardboard die-cutting; the cleaning component 6 is used to clean the waste formed after the cardboard die-cutting again; and the collecting component 7 is used to collect the cleaned waste for subsequent centralized treatment.

[0058] The two blowing components 5 correspond to the two transport components 22 one by one, and include a fan 51 and a blowing pipe 52 .

[0059] The fan 51 is fixedly mounted on the top of the frame 21 and is located above the transport assembly 22. The air blowing pipe 52 is also fixedly mounted on the frame 21, one end of which is fixedly connected and communicated with the fan 51, and the other end extends into the corresponding clearance space 4. When the fan 51 is in operation, it can drive the gas to blow into the corresponding clearance space 4 along the air blowing pipe 52, and the air blowing pipe 52 can blow the gas in the clearance space 4 toward the conveyor belt 221 located below. In this embodiment, it is preferred that the extension direction of the air blowing pipe 52 is tilted downward as a whole toward the direction close to the die-cutting device 1, and it is preferred that the blowing direction of the air blowing pipe 52 in the clearance space 4 is also tilted downward toward the direction close to the die-cutting device 1. In this embodiment, since the fan 51 is a common prior art, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0060] When there is waste material on the edge of the paperboard entering the clearance space 4 , the gas blown out from the blowing pipe 52 will be able to blow the waste material away from the edge of the paperboard and move the waste material toward the direction close to the die-cutting device 1 .

[0061] Reference Figure 1 and Figure 2 The collecting assembly 7 is located at one side of the die-cutting device 1 close to the frame 21, and is located lower than the transporting assembly 22 and between the two transporting assemblies 22. When the waste leaves the edge of the board, the paperboard is further transported and can leave the paperboard and fall down from the space between adjacent paperboards and be collected by the collecting assembly 7.

[0062] Reference Figure 2 and Figure 3 The collecting assembly 7 includes a waste collecting member 71, a driving member 72 and a plurality of driving rollers 73. In this embodiment, the collecting assembly 7 preferably includes two driving rollers 73 in total.

[0063] The waste collecting member 71 is in the form of a flexible belt connected end to end.

[0064] The driving roller 73 is a cylindrical structure as a whole, and is rotatably mounted at the bottom of the frame 21, and its rotation axis coincides with its own axis and is parallel to the width direction of the frame 21. The axes of the two driving rollers 73 are parallel to each other, and the two driving rollers 73 are aligned along the length direction of the frame 21.

[0065] The waste collecting member 71 is wound and installed on two driving rollers 73 at the same time. The outer surface of the waste collecting member 71 is provided with a plurality of grooves 711 for waste to stay, and the plurality of grooves 711 are evenly spaced along the winding track of the waste collecting member 71 .

[0066] The driving member 72 is fixedly mounted on one side of the frame 21, and can drive a driving roller 73 to rotate relative to the frame 21; during the rotation of the driving roller 73, the waste collecting member 71 can be driven to move along its winding track, and at the same time, the waste collecting member 71 can drive another driving roller 73 to rotate synchronously. In this embodiment, the driving member 72 is preferably a servo motor; since the servo motor is a common prior art, it will not be described in detail here, and it is only briefly shown in the drawings.

[0067] When the waste falls onto the waste collecting member 71, the waste will stay in the multiple grooves 711 on the waste collecting member 71; when the driving member 72 drives the waste collecting member 71 to move, the waste falling onto the waste collecting member 71 can be driven to move, and finally the waste collecting member 71 is removed from the waste collecting member 71 and falls to one side of the waste collecting member 71, and is collected uniformly by a container. In this embodiment, it is preferred that the collecting assembly 7 can move the collected waste to the side away from the die-cutting device 1 for uniform collection, and the container for uniformly collecting the waste is omitted in the drawings.

[0068] Reference Figure 2 and Figure 3 In order to facilitate the blowing assembly 5 to blow away the waste and blow the waste away from the paperboard to make it fall onto the waste collecting part 71, it is preferred that two baffles 213 are fixedly installed on the frame 21, and the two baffles 213 correspond to the two clearance spaces 4 one by one.

[0069] The baffle 213 is located on the side of the clearance space 4 away from the other clearance space 4, and the baffle 213 covers the opening of one side of the clearance space 4 to prevent the waste blown away by the blowing assembly 5 from falling from the side of the clearance space 4 away from the other clearance space 4, resulting in the waste being unable to fall onto the waste collecting part 71.

[0070] In order to further improve the blowing effect of the blowing assembly 5 on waste, it is preferred that the end of the blowing pipe 52 close to the clearance space 4 is tapered, and the air outlet of the blowing pipe 52 can cover the conveyor belt 221 located below along the width direction of the frame 21, so that the gas blown out of the blowing pipe 52 can fully blow away the waste existing on the edge of the plate.

[0071] At this time, the waste blown away by the blowing assembly 5 will move toward the direction close to the guide roller 211. Part of the waste will move toward the center of the paperboard under the interference of the guide roller 211 and the baffle 213, and part of the waste will pass through the gap between the guide roller 211 and the paperboard. Finally, after leaving the paperboard, the waste can fall down to the waste collecting part 71 for collection.

[0072] Reference Figure 2 and Figure 3The cleaning assembly 6 includes a cleaning brush 61 with a large number of bristles, and the bristles of the cleaning brush 61 are flexible and elastic. The cleaning brush 61 is a rectangular sheet structure as a whole, located in the clearance space 4, and located on the side of the air outlet of the air blow pipe 52 away from the guide roller 211; one end of the cleaning brush 61 in the length direction is fixedly connected to the frame 21, and partly crosses the top of the conveyor belt 221 located below; the cleaning brush 61 is installed with the bristles facing downward, and the distance between the bottom of the cleaning brush 61 and the conveyor belt 221 located below is less than the thickness of the cardboard. In this embodiment, it is preferred that the cleaning brush 61 is installed in a state where the length direction is horizontal and perpendicular to the conveying direction of the cardboard.

[0073] At this time, during the transportation of the cardboard, after the blowing assembly 5 blows away the waste on the edge of the board, the cleaning brush 61 will contact and abut against the surface of the top of the edge of the board, and clean the waste on the edge of the board again in a manner of brush removal to ensure the effect of waste cleaning. During the transportation of the cardboard, the waste removed by the cleaning brush 61 will be intercepted by the cleaning brush 61 and remain on the side of the cleaning brush 61 close to the die-cutting device 1; when the cardboard is transported away, the waste removed and intercepted by the cleaning brush 61 will fall down onto the waste collection member 71.

[0074] The implementation principle of a waste cleaning device for carton processing in the embodiment of the present application is as follows:

[0075] After the two sides of the paperboard are die-cut to form foldable edges, they are sent to the transport device 2, and the two transport components 22 drive the paperboard to continue to be transported to the subsequent folding device;

[0076] When the cardboard enters the transport device 2, the blowing assembly 5 will first blow away the waste at the edge of the cardboard. After some of the waste is blown away, the subsequent cardboard will fall down to the waste collection unit 71 for collection after being transported away;

[0077] After the blowing component 5 blows away the waste at the edge of the board, the cleaning component 6 clears the remaining waste at the edge of the board. While clearing the waste, it can prevent the waste from continuing to move with the cardboard. After the subsequent cardboard is transported away, the waste will also fall down to the waste collection component 71 for collection.

[0078] Embodiment 2:

[0079] Reference Figure 2 and Figure 4 The difference between this embodiment and embodiment 1 lies in the baffle 213, the cleaning component 6 and the blowing component 5.

[0080] Reference Figure 4 and Figure 5In order to reduce the probability that the waste on the board edge remains in the clearance space 4 after being cleaned, causing the waste to continue to be transported away with the cardboard on the board edge, it is preferred that the baffle 213 has a guide surface 2131 for guiding the gas flow on the side close to the clearance space 4.

[0081] The bottom of the guide surface 2131 is an arc-shaped surface, and its arc-shaped trajectory is perpendicular to the transportation direction of the paperboard. The tangent line of one end of the bottom of the guide surface 2131 extends along the width direction of the frame 21 in the direction close to the clearance space 4, and the position is flush with the bottom surface of the conveyor belt 221 located above. At this time, after the gas blown out from the air blowing pipe 52 contacts the guide surface 2131, the guide surface 2131 can guide the gas to move along the arc-shaped surface, and blow to the edge of the board in the direction close to the clearance space 4, so as to move the blown waste to a position close to the center of the paperboard.

[0082] The cleaning assembly 6 further includes a support frame 62, and the cleaning brush 61 is in a flexible belt-like structure connected end to end.

[0083] The support frame 62 is installed in the clearance space 4, one end of which is fixedly connected to the baffle 213, and the other end of which has a mounting portion 621 for mounting the cleaning brush 61.

[0084] A distance is maintained between the mounting portion 621 and the conveyor belt 221 located below; the length direction of the mounting portion 621 is inclined relative to the conveying direction of the cardboard, and is inclined along the conveying direction of the cardboard toward another clearance space 4; at the same time, the direction of the mounting portion 621 is also inclined relative to the thickness direction of the cardboard being transported, and is inclined downward along the vertical direction toward another clearance space 4.

[0085] Rotating wheels 622 are rotatably mounted at both ends of the mounting portion 621 in the length direction. The rotating wheel 622 is a cylindrical structure as a whole. The rotation axis of the rotating wheel 622 coincides with its own axis and is perpendicular to the length direction of the mounting portion 621. The rotation axis of the rotating wheel 622 is inclined relative to the transportation direction of the cardboard and along the transportation direction of the cardboard toward a direction away from the other clearance space 4, and is inclined relative to the thickness direction of the cardboard being transported toward a direction away from the other clearance space 4.

[0086] The parts other than the bristles of the cleaning brush 61 are simultaneously wound around and installed on the two rotating wheels 622. When the cardboard is transported passing by, the bristles of the cleaning brush 61 can all contact and abut against the edge of the cardboard, and the degree of contact between the different bristles on the cleaning brush 61 and the edge of the cardboard increases as the distance between the cleaning brush 61 and the baffle 213 increases.

[0087] At this time, in the process of removing waste materials at the edge of the board, the cleaning brush 61 can play the role of two rows of bristles to remove waste materials from the edge of the board, thereby effectively improving the cleaning effect of the cleaning brush 61 on the waste materials.

[0088] When the edge of the cardboard is transported under the cleaning brush 61, the friction between the bristles of the cleaning brush 61 away from the adjacent baffle plate 213 and the edge of the cardboard is greater than the friction between the bristles of the cleaning brush 61 close to the adjacent baffle plate 213 and the edge of the cardboard. Therefore, the cleaning brush 61 causes less wear on the die-cutting position of the cardboard edge and can effectively guide the removed waste to move along the distribution trajectory of the bristles on the cleaning brush 61 toward the center of the cardboard.

[0089] In addition, the edge of the cardboard exerts different forces on different bristles of the cleaning brush 61, which can drive the cleaning brush 61 to move along its own winding trajectory relative to the mounting portion 621, and drive the waste intercepted by the cleaning brush 61 after being cleared to move along the distribution trajectory of the bristles on the cleaning brush 61 toward the center of the cardboard.

[0090] After the waste material removed by the cleaning component 6 moves toward the center of the cardboard, in order to reduce the probability of the waste material continuing to move with the cardboard during transportation, the air outlet of the blowing pipe 52 is preferably extended and expanded toward the direction close to another blowing pipe 52, so that the gas blown out from the blowing pipe 52 can be blown onto the waste material guided by the cleaning component 6 to move toward the center of the cardboard, and drive the waste material to move relative to the cardboard toward the die-cutting device 1.

[0091] Preferably, the blowing direction of the blowing pipe 52 at the position where its air outlet extends and expands is tilted downward toward the die-cutting device 1 relative to the width direction of the frame 21, and is tilted downward toward the other blowing pipe 52 relative to the vertical direction.

[0092] At this time, the air blowing pipe 52 can not only blow the waste materials removed and intercepted by the cleaning component 6 off the cardboard in transport, but also drive the blown waste materials to move further toward the center of the cardboard, further increasing the probability that the waste materials will eventually fall onto the waste collecting part 71.

[0093] The implementation principle of a waste cleaning device for carton processing in the embodiment of the present application is as follows:

[0094] After the blowing component 5 blows away the waste at the edge of the board, the cleaning component 6 removes the remaining waste at the edge of the board, and at the same time, it can prevent the waste from continuing to move with the paperboard;

[0095] When the cleaning brush 61 moves along with the paperboard transportation, the waste intercepted by the cleaning brush 61 can be driven to move along the distribution track of the bristles on the cleaning brush 61 toward the center of the paperboard; when the waste moves to the point where it is no longer in contact with the cleaning brush 61, the gas blown from the expanded position of the air outlet of the blowing pipe 52 can blow the waste, so that the waste moves on the paperboard relative to the paperboard toward the die-cutting device 1, and finally leaves the paperboard and falls onto the waste collecting member 71;

[0096] The waste materials dropped onto the waste collecting member 71 will stay in the plurality of grooves 711 , and will move along with the movement of the waste collecting member 71 and be dumped into a container on one side for unified collection, so as to facilitate the staff to carry out centralized treatment of the waste materials later.

[0097] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
