[0031] 4. Under the action of the first electric telescopic rod, the support spacing of the scissor-type bracket can be adjusted, thereby adjusting the spacing between the two fixed plates, so that the first discharge wheel and the second discharge wheel on the two fixed plates can be the same as the width of the cardboard to be indented. At the same time, under the action of the second electric telescopic rod, the position of the transmission motor can be adjusted, so that after adjusting the spacing between the two first discharge wheels, the transmission motor can still drive the two first discharge wheels through the first transmission belt, ensuring that cardboards of different specifications can be sent out of the machine base.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0043] Please also see Figures 1 to 7 A preferred embodiment of the present invention is a creasing machine for making cartons, comprising a machine base 1 and a creasing device 2, a pushing device 3 and a discharging device 4 arranged on the machine base 1, wherein the pushing device 3 and the discharging device 4 are respectively located at two ends of the creasing device 2.

[0044] The indentation device 2 includes a pressing plate 21 and a transmission mechanism. The pressing plate 21 is located above the machine base 1. Both sides of the pressing plate 21 are slidably connected to the machine base 1 through a connecting shaft 22, and a pressing channel is formed between the pressing plate 21 and the machine base 1. The transmission mechanism is used to make the pressing plate 21 reciprocate along the axial direction of the connecting shaft 22 to indent the cardboard on the machine base 1.

[0045] Guide members 11 are respectively provided on both sides of one end of the pressing passage toward the pushing device 3 , so that the paperboard passes through the pushing device 3 and enters the creasing device 2 along the two guide members 11 .

[0046] The pushing device 3 of this embodiment is arranged at one end of the machine base 1, and the pushing device 3 includes a pushing piece 31 and an electric push rod 32. One end of the electric push rod 32 is fixedly connected to one end of the machine base 1, and the other end faces the indentation device 2 and is fixedly connected to the pushing piece 31.

[0047] The pressing plate 21 is provided with a limiting mechanism, such as Figure 6As shown, the limiting mechanism includes a fixed sleeve 5, a limiting member 51 and an electromagnet 52. The fixed sleeve 5 is fixedly connected to the side of the pressing plate 21 facing away from the pushing device 3. The fixed sleeve 5 is provided with a cavity 501, and the end of the fixed sleeve 5 facing the machine base 1 is provided with an opening 502 connected with the cavity 501. The limiting member 51 is slidably connected with the cavity 501 through the opening 502. A limiting spring 53 is provided in the cavity 501. The two ends of the limiting spring 53 are respectively abutted against the fixed sleeve 5 and the limiting member 51. Under the elastic force of the limiting spring 53, the end of the limiting member 51 facing away from the fixed sleeve 5 can abut against the machine base 1, so that the cardboard can be pushed into the pressing channel by the pushing device 3 and abut against the limiting member 51.

[0048] The electromagnet 52 is arranged at one end of the cavity 501 away from the opening 502, and the electromagnet 52 and the fixing sleeve 5, and an iron block 54 is arranged at one end of the limiter 51 facing the cavity 501. When the electromagnet 52 is energized, the limiter 51 can be sucked into the cavity 501, so that the cardboard after indentation can be sent out by the discharging device 4.

[0049] Under the action of the pushing device 3, the cardboard can be pushed, and under the guidance of the guide member 11, the cardboard can be accurately fed into the creasing device 2. When the cardboard abuts against the limiting member 51, it proves that the cardboard has completely entered the creasing device.

[0050] Through the transmission mechanism, the pressing plate 21 reciprocates along the axial direction of the connecting shaft 22, so as to indent the cardboard on the machine base 1. Since the two ends of the limit spring 53 are respectively in contact with the fixing sleeve 5 and the limit member 51, when the pressing plate 21 is pressed down, the limit member 51 can be embedded in the cavity 501 to prevent the limit member 51 from colliding with the machine base 1. When the cardboard is indented, the electromagnet 52 is energized, so that the limit member 51 can be sucked into the cavity 501, so that when the discharging device 4 sends out the cardboard, the limit member 51 will not block the discharge of the cardboard. In this embodiment, the cardboard can be indented by placing the cardboard on the machine base 1, and the worker does not need to get close to the indentation mechanism, which ensures the safety of the worker and avoids accidents.

[0051] like Figure 2 As shown, the pressing plate 21 of this embodiment is provided with an indentation template 211 on the side facing the machine base 1, and the two sides of the indentation template 211 are fixedly connected to the pressing plate 21 by screws 212; the guide member 11 is connected to the machine base 1 through a connecting frame 12, and both ends of the connecting frame 12 are fixedly mounted on the machine base 1, and the connecting frame 12 is provided with a penetrating slide groove 121, and the guide member 11 is located between the connecting frame 12 and the machine base 1, one side of the guide member 11 is connected to the slide groove 121 by a screw 111, and the other side abuts against the machine base 1, and the distance between the two guide members 11 can be adjusted by loosening the screw 122.

[0052] Since both sides of the creasing template 211 are fixedly connected to the pressing plate 21 by screws 212, the creasing template 211 can be replaced by unscrewing the screws 212 to achieve creasing of paperboards of different sizes. At the same time, by loosening the screws 122, the distance between the two guides 11 can be adjusted so that the width of the paperboard is the same as the distance between the two guides 11, ensuring that the paperboard can be accurately fed into the creasing device 2.

[0053] like Figure 2 As shown, the present embodiment has two transmission mechanisms, and the two transmission mechanisms are respectively located on both sides of the machine base 1, each transmission mechanism includes a pressing motor, a transmission disk 7 and a transmission rod 71, the transmission disk 7 is rotatably connected to one side of the machine base 1, and the transmission disk 7 is driven by the pressing motor, one end of the transmission rod 71 is rotatably connected to the eccentric circle of the transmission disk 7, and the other end is rotatably connected to the pressure plate 21.

[0054] Driven by the pressing motor, the transmission disc 7 rotates. Since one end of the movable rod 71 is rotationally connected to the eccentric circle of the transmission disc 7, one end of the transmission rod 71 performs eccentric circular motion, so that the pressing plate 21 can reciprocate along the axial direction of the connecting shaft 22 to indent the cardboard on the machine base 1.

[0055] Two rack grooves 72 are provided on each side of the pressing plate 21, one rack groove 72 is fixedly connected to the pressing plate 21, and the other rack groove 72 is slidably connected to the pressing plate 21, and a snap-fit ​​gear plate 721 is provided between the two rack grooves 72.

[0056] A fixed shaft 73 is rotatably set at the center of the gear plate 721, and the end of the transmission rod 71 away from the transmission plate 7 is embedded in the fixed shaft 73 and is rotatably connected to the fixed shaft 73. The fixed shaft 73 is sleeved with a nut 74, which is threadedly connected to the fixed shaft 73, and the nut 74 can limit the transmission rod 71 on the fixed shaft 73.

[0057] Since the gear plate 721 is slidably connected to the pressure plate 21, under the action of the bolt 722, the two rack grooves 72 can clamp the gear plate 721 to fix the gear plate 721 in the current position. At the same time, the transmission rod 71 is rotationally connected to the fixed shaft 73, so that the transmission rod 71 can drive the pressure plate 21 to reciprocate.

[0058] The indentation depths required for cardboards of different thicknesses are different. By loosening the bolt 722, a rack groove 72 can slide on the pressing plate 21, so that the gear plate 721 is separated from the rack groove 72. By adjusting the height position of the gear plate 721, the indentation depth of the pressing plate 21 can be adjusted to ensure that the cardboard has a suitable indentation depth, prevent thinner cardboard from being broken by the pressing plate 21, or prevent thicker cardboard from being unable to be effectively indented.

[0071] Under the action of the first electric telescopic rod 602, the support spacing of the scissor-type bracket 6 can be adjusted, thereby adjusting the spacing between the two fixed plates 40, so that the first discharge wheel 41 and the second discharge wheel 42 on the two fixed plates 40 can be the same as the width of the paperboard to be indented. At the same time, under the action of the second electric telescopic rod 603, the position of the transmission motor 43 can be adjusted, so that after adjusting the spacing between the two first discharge wheels 41, the transmission motor 43 can still drive the two first discharge wheels through the first transmission belt 441, ensuring that paperboards of different specifications can be sent out of the machine base 1.

[0072] like Figure 1 As shown, in this embodiment, the base 1 between the pressing plate 21 and the pushing device 3 is a loading part 101, and a loading device 8 is provided on one side of the loading part 101. The loading device 8 includes a loading frame 81, a support plate 82, a lift 83, an infrared sensor 84 and a feeding mechanism.

[0073] The loading rack 81 is fixedly arranged on one side of the machine base 1, and an opening is arranged on the top of the loading rack 81; the support plate 82 is located in the loading rack 81 and is slidably connected to the loading rack 81, and the support plate 82 is used for stacking cardboards; the elevator 83 is a worm gear elevator, the elevator 83 is located in the loading rack 81, and the two ends of the elevator 83 are respectively fixedly connected to the loading rack 81 and the support plate 82, the infrared sensor 84 is arranged at the opening of the loading rack 81, and the infrared sensor 84 is electrically connected to the elevator 83, the infrared sensor 84 is used to detect the height of the stacked cardboards on the support plate 82, and the infrared sensor 84 can control the lifting and lowering of the elevator 83 so that the top layer of cardboard on the support plate 82 is aligned with the infrared sensor 84.

[0074] The feeding mechanism is used to transport the topmost cardboard of the support plate 82 to the loading portion 101 .

[0075] In this embodiment, the feeding mechanism includes a pneumatic slide rail 9, a slider 91 and a pneumatic suction cup 92. The pneumatic slide rail 9 is fixedly connected to the loading rack 81, the slider 91 is slidably connected to the pneumatic slide rail 9, and the slider 91 is driven by the pneumatic slide rail 9; at least two pneumatic suction cups 92 are provided, the pneumatic suction cups 92 are fixedly connected to the slider 91, and the pneumatic suction cups 92 are facing away from the pneumatic slide rail 9.

[0076] When the pneumatic suction cup 92 sucks the top layer of cardboard on the support plate 82 to the loading part 101, the infrared sensor 84 senses that the height of the cardboard stacked on the support plate 82 becomes lower, and the infrared sensor 84 controls the elevator 83 to rise through the controller until the height of the top layer of cardboard on the support plate 82 is aligned with the detection angle of the infrared sensor 84, so that the pneumatic suction cup 92 can suck the cardboard on the support plate 82 again next time.

[0077] The steps of using the creasing machine for making cartons in this embodiment are as follows:

[0078] S1. Adjust the distance between the two guide members 11 so that the distance between the two guide members 11 is equal to the width of the paperboard; adjust the distance between the two fixing plates 40 so that the distance between the first discharge wheel (41) and the second discharge wheel (42) on both sides is the same as the width of the paperboard. According to the thickness of the paperboard, the height position of the gear plate 721 is adjusted to ensure that the paperboard has a suitable indentation depth.

[0079] S2 . Stack the cardboards on the support plate 82 , and align the topmost cardboard on the support plate 82 with the infrared sensor 84 .

[0080] S3. The pneumatic slide rail 9 drives the pneumatic suction cup 92 to move, and the pneumatic suction cup 92 absorbs the top layer of the cardboard on the support plate 82 to the feeding part 101; the electric push rod 32 is controlled, and the electric push rod 32 drives the pusher 31 to push the cardboard on the feeding part 101 into the pressing channel. When the cardboard abuts against the limiter 51, the electric push rod 32 controls the pusher 31 to reset.

[0081] S4. Driven by the pressing motor, the transmission disc 7 rotates. Since one end of the movable rod 71 is rotationally connected to the eccentric circle of the transmission disc 7, one end of the transmission rod 71 performs eccentric circular motion, so that the pressing plate 21 can reciprocate along the axial direction of the connecting shaft 22 to indent the cardboard on the machine base 1.

[0082] S5. After the creasing is completed, the cardboard is sent out of the machine base 1 under the drive of the first discharging wheel 41 and the second discharging wheel 42.
