[0041] Embodiment 1

[0042] In view of the defects existing in the above-mentioned existing low-noise paper feeding devices, based on the rich practical experience and professional knowledge in the design and manufacture of such products for many years by the applicant, and in cooperation with the application of theory, active research and innovation have been carried out in the hope of creating a technology that can solve the defects in the prior art, making the low-noise paper feeding device more practical. After continuous research, design, and repeated trial production of samples and improvement, the present utility model with practical value has finally been created.

[0043] Please refer to Figures 1 to 4 , an embodiment of the present utility model provides a low-noise paper feeding device, including a material selection rack 1 that can be lifted along a first direction and a plurality of sliding paper feeding components 2 installed on the material selection rack 1. The heights of different sliding paper feeding components 2 are different, and different sliding paper feeding components 2 can feed corrugated cardboard with different thickness specifications to the cutting knife group.

[0044] On the material selection rack 1, several groups of horizontal slide rails 101 with different heights are installed, and a sliding feeding component 2 is slidably installed on each group of horizontal slide rails 101. The sliding feeding component 2 can slide along the horizontal slide rail 101 in the second direction to convey cardboard, and the second direction is not parallel to the first direction; a magnetic attraction component 3 for adsorbing the sliding feeding component 2 at the initial feeding position is also installed on the material selection rack 1; along the second direction, the magnetic attraction component 3 and the sliding feeding component 2 are arranged in sequence. In this embodiment, the second direction is perpendicular to the first direction, and the first direction is the vertical direction. Of course, the first direction can also be a direction inclined to the horizontal plane.

[0045] In this embodiment, during the lifting process of the material selection rack 1, under the magnetic attraction force of the magnetic attraction component 3, the sliding feeding component 2 is adsorbed at the initial feeding position, and the acting force of the magnetic attraction component 2 can effectively reduce the shaking amplitude of the sliding feeding component 2 during the lifting process, so as to reduce the noise generated by the sliding feeding component 2 during the lifting process of the material selection rack 1 along the first direction. As Figure 2 shown, the magnetic attraction component 2 adsorbing the sliding feeding component 2 can effectively reduce vibration and noise, reduce noise, and avoid excessive noise.

[0046] Optionally, the magnetic attraction component 3 includes a fixing plate 31 fixedly connected to the material selection rack 1, and several magnets 32 are installed at intervals on the fixing plate 31. The positions of the several magnets 32 correspond to the positions of the several sliding feeding components 2 one by one. In this embodiment, each magnet 32 correspondingly adsorbs a sliding feeding component 2, so that the noise of each sliding feeding component 2 during the lifting process becomes smaller. As Figure 2 shown, the structure in this embodiment is equivalent to reducing the rolling degree of the end rollers of the sliding feeding component 2. The smaller the movement amplitude of the rollers during the lifting process, the less likely it is to generate a large collision noise. It should also be noted that components such as the first guide wheel 233 and the second guide wheel 234 on the sliding feeding component 2 are also likely to generate noise during the shaking process. Therefore, when the main body of the sliding feeding component 2 is adsorbed, the shaking degree of the easily shaken components such as the first guide wheel 233 and the second guide wheel 234 will also be significantly reduced, which is also beneficial to reducing noise.

[0047] Optionally, the low-noise paper feeding device further includes a support frame 4 and a lifting drive device 5. A vertical track 401 is installed on the support frame 4, and the lifting drive device 5 is installed on the support frame 4; the material selection rack 1 is slidably installed on the vertical track 401, and the lifting drive device 5 is used to drive the material selection rack 1 to slide along the vertical track 401. The support frame 4 plays a supporting role. The lifting drive device 5 is used to drive the material selection rack 1 to lift. The lifting drive device 5 includes a drive motor, a driving sprocket, a transmission chain, etc. The drive motor drives the driving sprocket to rotate, thereby driving the transmission chain to move, and the transmission chain drives the material selection rack 1 to lift.

[0048] Optionally, the sliding feeding assembly 2 includes a main frame 21 and a paper clamping device 22 mounted on the main frame 21; a gap 201 for the cardboard to pass through is provided on the main frame 21, and the paper clamping device 22 includes a clamping plate 221 located on one side at the bottom of the gap 201 and a telescopic device 222 located on one side at the top of the gap 201. A pressing head for pressing the cardboard against the clamping plate 221 is mounted on the telescopic shaft of the telescopic device 222. Preferably, the top surface of the clamping plate 221 is flush with the bottom surface of the gap 201. As Figure 4 shown, the telescopic device 222 clamps or releases the cardboard by controlling the height of the pressing head. Generally, when the sliding feeding assembly 2 moves leftward to the feeding position as Figure 4 shown, the telescopic device 222 controls the pressing head to rise to release the cardboard, and then the sliding feeding assembly 2 moves rightward to the initial feeding position. When it is necessary to switch the cardboard, the telescopic device 222 clamps the cardboard by controlling the pressing head to descend. After cutting the cardboard, the lifting drive device 5 drives the material selection rack 1 to lift and lower.

[0049] Optionally, a paper guiding device 23 is also mounted on the main frame 21, and the paper guiding device 23 and the paper clamping device 22 are located on opposite sides of the main frame 21; the paper guiding device 23 includes a first guiding rod 231 and a second guiding rod 232, and a guiding opening for guiding the cardboard to the gap 201 is formed between the first guiding rod 231 and the second guiding rod 232. The arrangement of the paper guiding device 23 can enable the cardboard to accurately enter the gap 201.

[0050] Optionally, a first guiding wheel 233 is mounted at the end of the first guiding rod 231 away from the main frame 21, and a second guiding wheel 234 is mounted at the end of the second guiding rod 232 away from the main frame 21. The arrangement of the first guiding wheel 233 and the second guiding wheel 234 can make the process of the cardboard entering the gap 201 smoother and reduce the possibility of the cardboard being scratched.

[0051] Optionally, the magnet 32 is mounted on one side of the fixing plate 31 close to the sliding feeding assembly 2.

[0052] In another specific embodiment, a mounting groove is provided on the fixing plate 31, and the magnet 32 is mounted in the mounting groove. The magnet 32 does not protrude from the side of the fixing plate 31 close to the sliding feeding assembly 2, which can better avoid the occurrence of the situation where the magnet 32 is broken by being hit.

[0054] This embodiment discloses a paper cutting machine, including the low-noise paper feeding device described in any one of the above.

[0055] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby.
