Description

Technical Field

[0001] The utility model belongs to the field of cutting equipment, relates to the cutting of cardboard, and specifically relates to an environmentally friendly packaging carton cutting equipment capable of recycling paper scraps. Background Art

[0002] Cardboard is a common packaging material, which is usually made of cardboard. When using cardboard to make cartons, the cardboard needs to be cut. Laser cutting machines are usually used to cut cardboard. Laser cutting machines have higher cutting accuracy and are more efficient. In order to ensure the continuity of cardboard cutting, laser cutting machines with conveyor belts are used to continuously transport cardboard to the laser cutting head so that the laser cutting machine can continuously cut the cardboard.

[0003] However, existing laser cutting machines usually do not have a recycling structure for cardboard waste. The waste debris generated by cutting falls directly to the working ground along the conveyor belt and is subsequently cleaned up. Alternatively, a box is placed under the laser cutting machine to collect the waste after it falls into the box. However, the free fall of the waste usually prevents some of the waste from falling into the box. The waste scattered around the laser cutting machine affects the working environment and reduces the efficiency of waste recycling. Utility Model Content

[0004] In order to solve the technical problem that the waste collection structure is not available during the cardboard cutting process, which reduces the recycling of waste and reduces the recycling rate, the utility model provides an environmentally friendly packaging carton cutting device that can recycle paper scraps. A frame is set up on the laser cutting machine to support the roller pressure shaft and the guide plate. The roller pressure shaft improves the stability of cardboard cutting, and the guide plate guides the fallen waste into the recycling box, thereby improving the recycling efficiency and recycling effect of the waste.

[0005] The technical solution adopted by the utility model is: to provide an environmentally friendly packaging carton cutting device for recyclable paper scraps, including a laser cutting machine composed of a machine body, a conveyor belt and a laser cutting head, wherein a frame is arranged around the machine body, a roller shaft is arranged on the rear side of the frame for vertical lifting by means of a track, and the roller shaft abuts against the top surface of the conveyor belt; an open recycling box is arranged on the front side of the frame, a drainage plate is detachably installed on the top of the rear side of the recycling box, the drainage plate is detachably installed on the frame with the help of a supporting shaft, and the drainage plate is tilted upward to the bottom of the front side of the conveyor belt; a brush is detachably installed on the outer wall of the drainage plate, and the brush is in contact with the outer surface of the conveyor belt.

[0006] The frame is set up on the side of the laser cutting machine, and the roller shaft set up on the rear side of the frame falls on the conveyor belt due to gravity. When the cardboard is led to the conveyor belt for cutting, the cardboard passes under the roller shaft, and the roller shaft presses the cardboard under gravity to prevent it from shaking during cutting, thereby improving cutting safety and ensuring cutting accuracy. The waste and debris generated by the cutting move to the front side with the conveyor belt, and the guide plate set up in front of the frame tilts upward and extends to the bottom of the conveyor belt. After the waste transported by the conveyor belt is reversed, the waste falls onto the guide plate, the bottom of the guide plate is vertically downward, and a recycling box is installed, so that the waste falls along the guide plate into the recycling box for collection, and the brush installed on the guide plate contacts the transmission belt, thereby cleaning the surface of the conveyor belt after the reversal to clean up the adhered debris, thereby improving the cleaning and recycling effects.

[0007] To further optimize the technical solution, bearings are sleeved on both sides of the roller shaft, and sliding blocks are sleeved outside the bearings, and the sliding blocks are slidably installed on the rails respectively.

[0008] Bearings are installed on both sides of the roller shaft, and are installed through sliders and tracks on the bearings, so that the roller shaft falls on the cardboard pair under gravity. When the cardboard is constrained, the cardboard moves with the conveyor belt, and the roller shaft rotates along the bearing, thereby reducing the friction resistance of the cardboard and making the cardboard move smoothly.

[0009] To further optimize the technical solution, the slider is provided with a through hole, the bearing is sleeved in the through hole, and retaining rings are clamped on both sides of the through hole, and the retaining rings are respectively abutted against the end faces of the bearing.

[0010] The slider is assembled with the bearing through the through hole, and retaining rings are arranged on both sides of the through hole. The retaining rings abut against the end faces of the bearings respectively, so as to constrain the bearings and prevent the bearings from falling off the slider, thereby ensuring safety in use.

[0011] To further optimize the technical solution, the track is divided into C-shaped steels on both sides of the roller shaft, the C-shaped steels are fixedly installed on the frame respectively, and the sliders are slidably installed on the C-shaped steels respectively.

[0012] The C-shaped steel fixedly installed on the frame provides a restraining effect for the slider, so that the roller pressing shaft can only be lifted and lowered vertically along the C-shaped steel, and the pressing restraint on the cardboard is stable, and its structure is simple, reducing the use cost.

[0013] To further optimize the technical solution, the outer wall of the support shaft is evenly provided with connecting rings along the length direction, the connecting rings are welded and fixed to the bottom surface of the guide plate, and the connecting rings are locked and fixed to the support shaft by means of locking pieces.

[0014] The support shaft is assembled with the guide plate by means of a connecting ring, the connecting ring is welded and fixed on the bottom surface of the guide plate, and the support shaft is erected on the frame after being successively connected through, so as to support the guide plate and ensure stable use.

[0015] To further optimize the technical solution, the locking member includes a tightening bolt threadedly connected to the outer wall of the connecting ring, and the tightening bolts are all in contact with the outer wall of the supporting shaft.

[0016] After the support shaft passes through the connecting ring in sequence, the tightening bolts are tightened against the support shaft to enhance the firmness of the assembly of the support shaft and the connecting ring, thereby ensuring the reliability of the support for the guide plate.

[0017] To further optimize the technical solution, polygonal docking sleeves are arranged on both sides of the support shaft, the docking sleeves are slidably installed with the frame respectively, and the outer walls of the docking sleeves are fixedly sleeved with limit rings, and the limit rings are abutted against the outer walls of the frame; the docking sleeves are respectively plugged into the support shafts and pin-connected with the support shafts by means of pin connectors.

[0018] The support shaft is assembled on the frame through the docking sleeve. The docking sleeve moves along the frame to approach the support shaft and is sleeved with the support shaft. After being sleeved with the support shaft, the support shaft is supported. After the limit ring on the docking sleeve abuts against the outer wall of the frame, the support shaft is prevented from moving on the frame, and the use is stable and reliable.

[0019] To further optimize the technical solution, the pin connector includes a socket provided on the docking sleeve and the support shaft, and a pin shaft is inserted into the socket.

[0020] After the butt joint sleeve is plugged into the support shaft, the butt joint sleeve and the insertion hole on the support shaft overlap, so that the pin shaft can be inserted into the insertion hole to pin the support shaft and the butt joint sleeve, which is easy to use.

[0021] To further optimize the technical solution, the rear side wall of the recycling box is provided with a plurality of card slots, each of which is connected with a card block, and each of the card blocks is fixedly installed with the bottom of the outer wall of the drainage plate.

[0022] The recycling box is connected with the card block on the drainage plate through the card slot, so that the drainage plate supports the recycling box. The recycling box and the drainage plate are easy to disassemble and assemble, and the use is flexible and labor-saving.

[0023] To further optimize the technical solution, the outer wall of the guide plate is provided with a slot, and the slot is plugged into the brush.

[0024] The brush is plugged into the slot on the drainage plate, which is convenient for disassembly and maintenance of the brush and easy to use.

[0025] The beneficial effects of the utility model are:

[0026] 1. The roller shaft is mounted on the rear side of the frame and is installed in the C-shaped steel with the help of a slider. The C-shaped steel allows the roller shaft to move only in the vertical direction so that it is pressed on the cardboard by gravity to prevent the cardboard from moving during cutting and ensure cutting accuracy. When the transmission belt drives the cardboard to move, the roller shaft rotates along the bearing on the slider. The bearing reduces the rotation resistance of the roller shaft and the friction resistance of the roller shaft to the cardboard, making the cardboard conveying effortless and smooth.

[0027] 2. After the waste and debris generated by cardboard cutting move to the front end with the conveyor belt, they fall onto the guide plate as the conveyor belt changes direction. The guide plate is tilted and erected under the conveyor belt to comprehensively collect the waste and debris, and guide them so that they fall into the recycling box installed at the bottom of the guide plate, making recycling easier and improving recycling efficiency and effect;

[0028] 3. The guide plate is mounted on the frame with the help of the support shaft. After the support shaft passes through the connecting ring on the guide plate in turn, it is locked with the jacking bolt, and then the docking sleeve is plugged into the support shaft, and the two are pinned together by the pin shaft. The polygonal structure of the docking sleeve is installed in a linear sliding manner with the bracket to prevent the guide plate from deflecting, and the limiting ring on the docking sleeve abuts against the outer wall of the frame to restrict the position movement of the guide plate, which is reliable to use;

[0029] 4. When the guide plate guides the fallen waste materials into the recycling box, the brush on the top of the guide plate contacts the conveyor belt, thereby cleaning the surface of the belt, making the cleaning of debris on the surface of the belt more thorough, improving the recycling effect and increasing the flexibility of use.
