Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a rapid paper feeding device and a paper cutter. Background Art

[0002] A paper cutter is used for cutting corrugated paper, and includes a paper feeding device and a cutting device. The paper feeding device feeds a corrugated paper tape into the cutting device for cutting to obtain cartons of set sizes.

[0003] The Chinese invention patent with the publication number of CN108162485B discloses a power paper feeding device and a paper feeding pressure roller device. The power paper feeding device and the paper feeding pressure roller device pinch and feed the corrugated paper tape, and send the corrugated paper tape into a carton cutting device for cutting. The power paper feeding device includes a plurality of paper feeding rollers and a roller drive system for driving the paper feeding rollers to rotate.

[0004] In the power paper feeding device with the above structure, the power paper feeding device and the paper feeding pressure roller device pinch and feed the paper, and it is easy to completely flatten the corrugated paper tape (the distance between the power paper feeding device and the paper feeding pressure roller device is too small); in addition, the transmission structure of the roller drive system is relatively complex, and the rotation speed of the rollers is generally not suitable to be too fast, which also results in a relatively slow paper feeding speed (the conveying speed of the paper from the roller to the carton cutting device), and is not conducive to improving the efficiency of cutting corrugated paper.

[0005] In view of this, it is necessary to design a rapid paper feeding device and a paper cutter, which can avoid flattening the corrugated paper tape and is conducive to improving the paper feeding speed.

[0006] The above information is given as background information only to assist in understanding the present disclosure, and it is not determined or admitted whether any of the above content can be used as the prior art relative to the present disclosure. Summary of the Utility Model

[0048] In view of the above-mentioned defects existing in the existing rapid paper feeding device, based on the rich practical experience and professional knowledge accumulated by the applicant in the design and manufacture of such products for many years, and in combination with the application of scientific principles, the applicant has actively carried out research and innovation, hoping to create a technology that can solve the defects in the existing technology and make the rapid paper feeding device more practical. After continuous research, design, and repeated trial production of samples and improvements, the applicant finally created the present utility model that truly has practical value.

[0049] Please refer to Figures 1 to 3 , an embodiment of the present utility model provides a rapid paper feeding device, including: a support frame 1 for supporting; a feeding frame 2 including a clamping device 23 for clamping one end of a corrugated paper tape, and protruding columns 201 are provided at both opposite ends of the feeding frame 2; a pushing device 3 installed on the support frame 1, including a slider 31 slidably installed on the support frame 1 and a servo drive device 32 for driving the slider 31 to move in a set direction, and a groove 301 for the protruding column 201 to enter is provided on the slider 31; two pushing devices 3 are provided corresponding to the two protruding columns 201, and the two pushing devices 3 are symmetrically installed on the support frame 1 to push the feeding frame 2 to move in the set direction.

[0050] During actual use, the protruding columns 201 at both ends of the feeding frame 2 are respectively inserted into the two grooves 301, and then the two pushing devices 3 act synchronously to drive the slider 31 to move in the set direction, thereby driving the feeding frame 2 to move in the set direction, so as to convey the corrugated paper tape clamped by the clamping device 23 to a suitable position. In this embodiment, only the local area clamped by the clamping device 23 will be flattened, and the situation where the entire corrugated paper tape is clamped flat will not occur. In addition, in the pushing device 3 of this embodiment, the slider 31 is directly driven by the servo drive device 32 to move, without considering the transmission problem of the conveyor belt, with a faster response speed and can drive one end of the corrugated paper tape to a suitable position faster. It should also be added that during the cutting process of the cutting device, under the pulling force of the winding device or other devices, the corrugated paper tape continues to be conveyed forward. In addition, during the cutting of the corrugated paper tape, the clamping device 23 releases the clamping of the corrugated paper tape.

[0051] It should also be added that the set direction is generally a direction parallel to the horizontal plane. For example Figure 5 , at this time the set direction is the direction horizontally to the right.

[0052] Optionally, the pushing device 3 further includes a slide rail 33 fixedly connected to the support frame 1, the slide rail 33 is parallel to the set direction; a sliding block is slidably installed on the slide rail 33, and the slider 31 is fixedly connected to the sliding block; the slider 31 includes a transverse extension 311 extending towards the feeding frame 2, and the groove 301 is provided at the end of the transverse extension 311 close to the feeding frame 2.

[0053] The slide rail 33 defines the moving path of the slider 31, so that the end of the corrugated paper tape can accurately enter the cutting position. The arrangement of the transverse extension part 311 enables the protruding column 201 to enter the groove 301 more easily.

[0054] Optionally, the extending direction of the groove 301 is perpendicular to the set direction. Of course, the extending direction of the groove 301 can also be a direction inclined relative to the horizontal plane.

[0055] In a specific embodiment, the servo drive device 32 includes a servo motor 321, a lead screw 322 drivingly connected to the servo motor 321, and a lead screw nut 323 mounted on the lead screw 322; the slider 31 is connected to the lead screw nut 323, and the lead screw 322 is parallel to the set direction. The servo motor 321 drives the lead screw 322 to rotate, and then drives the slider 31 to translate along the slide rail 33.

[0056] Optionally, the fast paper feeding device further includes a lifting frame 4 and a lifting device 5 for lifting the height of the lifting frame 4; the lifting frame 4 is slidably mounted on the support frame 1 vertically; a plurality of layers of feeding racks 2 are all mounted on the lifting frame 4, pulleys are mounted at the ends of the feeding racks 2, a support track 41 for supporting the pulleys is mounted on the lifting frame 4, and the support track 41 is parallel to the set direction.

[0057] Specifically, the lifting device 5 can change the height of the lifting frame 4, so that the protruding columns of different feeding racks 2 are clamped into the grooves 301. Generally, the thicknesses of the corrugated paper tapes clamped by different feeding racks 2 are different, which achieves the purpose of flexible paper feeding.

[0058] Optionally, the feeding rack 2 further includes a main frame body 21 and a guiding assembly 22; a feeding through groove is provided on the main frame body 21, the guiding assembly 22 includes a first guiding column 221 and a second guiding column 222, the first guiding column 221 is located on one side of the top of the feeding through groove, the second guiding column 222 is located on one side of the bottom of the feeding through groove, and a feeding port for the corrugated paper tape to pass through is formed between the first guiding column 221 and the second guiding column 222. The arrangement of the guiding assembly 22 enables the corrugated paper tape to pass through the feeding through groove more easily, so that the end of the corrugated paper tape is clamped by the clamping device 23.

[0059] Optionally, the length of the first guiding column 221 is shorter than that of the second guiding column 222, so that the end of the corrugated paper tape can enter the gap between the first guiding column 221 and the second guiding column 222 more easily, and the second guiding column 222 has a better supporting effect on the corrugated paper tape.

[0060] Optionally, guiding wheels 223 are provided at the ends of the first guiding column 221 and the second guiding column 222. The arrangement of the guiding wheels 223 can effectively prevent the first guiding column 221 or the second guiding column 222 from scratching the surface of the corrugated paper tape.

[0061] Optionally, the clamping device 23 includes a downward pressing air cylinder 231 and a supporting plate 232 mounted on one side of the bottom of the downward pressing air cylinder 231; an elastic pressing block capable of pressing on the supporting plate 232 is provided on the telescopic shaft of the downward pressing air cylinder 231. When the telescopic shaft of the downward pressing air cylinder 231 extends, the end of the corrugated paper tape is pressed tightly on the supporting plate. When it is not necessary to clamp the corrugated paper tape, the telescopic shaft of the downward pressing air cylinder 231 can be retracted. In addition, the setting of the elastic pressing block can increase the contact area with the corrugated paper tape, improve the pressing effect, and prevent the corrugated paper tape from slipping off.
