Description

TECHNICAL FIELD

[0001] The present application relates to waste paper recycling device technical field, especially to a kind of paper cutting suction device and method of waste collection. BACKGROUND

[0002] Paper bag manufacturing needs to go through multi-process processing. The device is provided with a device for separating the two side surfaces of the uncut whole paper bag, leaving a gap between the upper surface and the lower surface of the paper bag strip. A shaft perpendicular to the whole paper bag is installed below the paper bag strip, and a U-shaped cutter is installed on the shaft. The U-shaped cutter is in contact with the lower surface of the paper bag to cut the U-shaped thumb position on the lower surface of the paper bag with each rotation of the shaft. The end of the U-shaped thumb position is also connected to the paper bag, which is cut off during subsequent processing. The U-shaped opening on the paper bag facilitates opening the paper bag and facilitates subsequent use.

[0003] The existing processing device installs a guillotine on the roller, which cuts off the paper bag with each rotation of the roller. The guillotine on the roller also removes the waste material while cutting off the paper bag. After the waste material is removed, it will be pulled by the edge of the cut and remain on the paper bag. In subsequent processes, the waste material will fall into the paper bag, which cannot meet the customer's requirements.

[0004] Therefore, the present application provides a paper cutting suction device and method capable of collecting waste. SUMMARY

[0007] The first aspect provides a paper cutting suction device capable of collecting waste, comprising a roller and a transmission shaft, and further comprising:

[0008] A guillotine is provided on the roller to cut off the paper bag.

[0009] A cylindrical base is fixedly sleeved on the side wall of the transmission shaft, and a strip-shaped support plate is provided on the cylindrical base. Gas holes are formed at the outer ends of the strip-shaped support plate, and a gas conveying groove is formed in the strip-shaped support plate and communicates with the gas holes. One end of the gas conveying groove is connected to a gas pressure control mechanism through a connecting gas pipe.

[0010] A support ring is rotatably connected to the gas pressure control mechanism, and the two side walls of the support ring are respectively connected to a suction pipe and a blowing pipe.

[0011] Preferably, the side wall of the cylindrical base is provided with a mounting groove, the strip-shaped support plate is fixed in the mounting groove by bolts, and the outer surface of the strip-shaped support plate is provided with an emptying groove, the length of the emptying groove being matched with the length of the guillotine.

[0012] The side wall of the roller is provided with a cutter groove, and a cutter holder is mounted in the cutter groove, and the cutter holder and the guillotine are fixed in the cutter groove by bolts.

[0013] Preferably, the roller and the end portion of the transmission shaft are respectively fixed with a driving gear and a driven gear, and the roller is connected with an external driving device.

[0014] The transmission shaft and the roller are relatively reversely rotated under the meshing transmission of the driving gear and the driven gear, the guillotine is downward when the strip-shaped support plate is upward, and the paper bag conveyed at the upper end of the cylindrical base is cut off.

[0015] Preferably, the air pressure control mechanism comprises a rotating disc fixedly sleeved at the end portion of the transmission shaft, the rotating disc is provided with a fan-shaped cavity, and one end of the connecting air pipe is in communication with the fan-shaped cavity.

[0016] Preferably, the inner walls of the two end portions of the support ring are connected with mechanical seals, and the two end portions of the rotating disc are fixedly connected with the inner rings of the two mechanical seals.

[0017] Preferably, the fan-shaped cavity and the inner wall of the support ring form an air conveying cavity.

[0018] When the air suction pipe is in communication with the fan-shaped cavity, the air blowing pipe is away from the fan-shaped cavity, and when the air blowing pipe is in communication with the fan-shaped cavity, the air suction pipe is away from the fan-shaped cavity.

[0019] Preferably, the air suction pipe is connected with an external air suction device, and the air blowing pipe is connected with an external air blowing device.

[0020] Preferably, the outer arc surface of the fan-shaped cavity is fixedly connected with an arc-shaped strip, the arc-shaped strip is slidingly connected with the inner wall of the support ring, so that the air conveying cavity formed by the fan-shaped cavity and the inner wall of the support ring also maintains an independent air conveying space in a dynamic state.

[0021] The second aspect provides a paper cutting and air suction method capable of collecting waste, comprising the following steps.

[0022] S1: the external driving device is turned on to rotate the roller, the transmission shaft is reversely rotated relative to the roller under the meshing transmission of the driving gear and the driven gear, and the paper bag is conveyed at the upper end of the cylindrical base.

[0023] S2: when the strip-shaped support plate is upward, the guillotine is downward to cut off the paper bag, and the guillotine also cuts off the waste at the same time.

[0024] S3: When the waste material is cut, it is located at the upper end of the air hole. At this time, the fan-shaped cavity is connected to the suction pipe, so that the air hole is in a negative pressure adsorption state, and the cut waste material is adsorbed at the air hole.

[0025] S4: The roller and drive shaft continue to rotate, the guillotine deflects upward, the strip support plate deflects downward, and the suction pipe remains connected to the fan-shaped cavity for a period of time (the time it takes for the drive shaft to rotate a quarter turn);

[0026] S5: When the strip support plate is deflected downwards, the fan-shaped cavity is connected to the air blowing pipe. At this time, the air hole is in a positive pressure blowing state, blowing the waste material down into the waste box.

[0028] Compared with the prior art, this application has the following beneficial technical effects:

[0029] This application opens an air hole at the upper end of the strip support plate. The air suction pipe is connected to the air hole through the connecting air pipe and the air delivery groove. When the gate cuts the paper bag and the U-shaped thumb position (waste), the air hole is in a negative pressure state, which adsorbs the cut waste at the outer end of the air hole. When the cylindrical base deflects to one side, it carries away the adsorbed waste, thus preventing the waste from being blown off.

[0030] By opening a fan-shaped cavity inside the turntable, when the strip support plate is deflected downwards, the connecting air pipe, the fan-shaped cavity and the blowing pipe are connected. The blowing pipe is connected to the external blowing device. At this time, the air hole is in a positive pressure blowing state, which can blow the adsorbed waste down into the waste collection box, avoiding the waste from continuously sticking to the outer port of the air hole and affecting the next waste adsorption.

[0031] In summary, the structure of this application is ingeniously designed. While cutting the paper bag, it can adsorb the cut waste onto the strip support plate. As the blade deflects, it can move the adsorbed waste to the other side, and under the action of the air pipe, the adsorbed waste is blown off. This allows for the cyclical cutting of paper bags and adsorption of waste, which is highly efficient and environmentally friendly, and the paper bags produced meet the needs of customers.
