Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a paper feeding device and a paper cutting machine. Background Art

[0002] Generally, a paper cutting machine conveys cardboard to a paper cutting device through a paper feeding device, and then the paper cutting device cuts out appropriate paper shapes to form cartons.

[0003] The paper feeding device in a paper cutting machine generally includes a plurality of support beams arranged at intervals, and the cardboard slides over the top surface of the support beams, so as to convey the cardboard towards the paper cutting device; there is generally a large buffer distance between the support beams and the paper cutting device, so that the cardboard can sag and bend for a certain length (having a certain stock buffer effect), but when the sagging and bending length of the cardboard is long, large shaking is likely to occur, which will easily cause the cardboard to deviate, affecting the actual paper cutting accuracy.

[0004] In view of this, it is necessary to design a paper feeding device and a paper cutting machine that can more accurately guide the cardboard to the paper cutting device.

[0005] 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

[0047] Embodiment 1

[0048] In view of the defects existing in the above-mentioned existing paper cutters, 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. After continuous research, design, and repeated trial production of samples and improvement, finally, this practical new model with practical value has been created.

[0049] Please refer to Figures 1 to 5The embodiment of the utility model provides a paper feeding device, including: a frame 100, which plays a supporting role, and the frame 100 includes a supporting beam 101, and the paperboard can slide along the top surface of the supporting beam 101; a paper guiding device 1, including a positioning guide plate 11 and a supporting rod group 12 installed on opposite sides of the supporting beam 101; the positioning guide plate 11 is installed on the supporting beam 101 to laterally position the paperboard, and the supporting rod group 12 is tilted to guide the paperboard to the paper cutting device at an angle; the positioning guide plate 11 is set on the incoming material side, and contacts the side edge of the incoming paperboard to laterally position the paperboard. The supporting rod group 12 is set on the discharging side of the supporting beam 101. When the paperboard sags to a large extent, the paperboard will slide along the top surface of the supporting rod group 12, thereby reducing the shaking degree of the paperboard, so that the paperboard can be stably transported forward.

[0050] like Figure 3 As shown, the supporting rod assembly 12 includes a cylinder 121 and a sliding telescopic rod 122 that is telescopically installed in the cylinder 121, and the extension length of the sliding telescopic rod 122 is adjustable. It should also be noted that the supporting rod assembly 12 can adjust the extension length of the sliding telescopic rod 122, thereby adjusting the buffer width of the cardboard, so that the shorter length of the drooping and bent cardboard is in an unsupported state, thereby reducing the possibility of the cardboard running off.

[0051] Optionally, a slide groove 102 is provided on the support beam 101, and the slide groove 102 is parallel to the center line of the support beam 101; the positioning guide plate 11 has a sliding portion slidably installed in the slide groove 102, and a fastener for fixing the positioning guide plate 11 on the support beam 101 is installed on the positioning guide plate 11; the fastener is detachably connected to the support beam 101. The positioning guide plate 11 slides along the slide groove 102 to adjust the positioning position, and after the positioning guide plate 11 is adjusted to a suitable position, the fastener fixes the positioning guide plate 11.

[0052] Optionally, a plurality of support beams 101 are arranged in the vertical direction; each support beam 101 is installed with a paper guide device 1; and a guide roller 103 is installed at the bottom of the top support beam 101 of two adjacent support beams 101. Each support beam 101 is used to convey a paperboard of a certain specification, thereby meeting the need of replacing different paperboards in the paper cutter.

[0053] Optionally, the inclination angle of the cylinder 121 is adjustable. It should be noted that, when the inclination angle of the cylinder 121 is different, the contact length of the cardboard cylinder is generally different. For example, under the premise that the length of the cardboard in the buffer distance is constant and the extended length of the sliding telescopic rod 122 is unchanged, the greater the inclination angle of the cylinder 121, the shorter the contact length between the cardboard and the supporting rod group 12. The inclination angle here refers to the acute angle formed between a horizontal line extending from a point at the tail end of the sliding telescopic rod 122 and the sliding telescopic rod 122.

[0054] Optionally, the rack 100 further includes a plurality of paper supporting rods 104 and a lateral bracket 105 for supporting the paper supporting rods 104; the paper supporting rods 104 are rotatably mounted on the lateral bracket 105. The presence of the paper supporting rods 104 can reduce the friction of cardboard conveyance, so that cardboard can be conveyed to the paper cutting device over a longer distance.

[0055] Optionally, the paper feeding device further includes a paper clamping and feeding structure 2; the paper clamping and feeding structure 2 includes a main frame body 21, a lateral positioning plate 22 mounted on the main frame body 21 near one side of the supporting rod group 12, a clamping device 23 mounted on the main frame body 21 for clamping the cardboard, and a translation driving device 24 for pushing the main frame body 21 to slide towards the paper cutting device; a paper passing slot for the cardboard to pass through is provided on the main frame body 21, and the lateral positioning plate 22 can slide and adjust its position along the center line direction of the supporting cross beam 101.

[0056] Optionally, an adjustment slot parallel to the supporting cross beam 101 is provided on the main frame body 21, and the sliding part of the lateral positioning plate 22 is slidably mounted in the adjustment slot. The lateral positioning plate 22 can slide along the adjustment slot, so as to adjust the position of laterally positioning the cardboard.

[0057] Optionally, the clamping device 23 includes a supporting plate 231 and a downward pressing air cylinder 232 for pressing the cardboard onto the supporting plate 231; the top surface of the supporting plate 231 is parallel to the bottom surface of the paper passing slot, and the downward pressing air cylinder 232 is located on one side of the top of the supporting plate 231, and the cylinder body of the downward pressing air cylinder 232 is fixedly connected to the main frame body 21. When the telescopic shaft of the downward pressing air cylinder 232 extends out, the cardboard can be clamped on the supporting plate 231.

[0058] Optionally, a guiding assembly is further mounted on the main frame body 21; the guiding assembly includes a first guiding rod 251 and a second guiding rod 252. The first guiding rod 251 is located on one side of the top of the paper passing slot, and the second guiding rod 252 is located on one side of the bottom of the paper passing slot. The length of the second guiding rod 252 is greater than the length of the first guiding rod 251, so as to better guide the cardboard into the paper passing slot.
