Description
Technical Field
[0001] This utility model relates to the field of kraft paper processing technology, specifically to a kraft paper flattening device. Background Technology
[0002] Kraft paperboard, also known as kraft paper or kraft linerboard, is one of the main types of paper used for cardboard boxes. Its main purpose is to bond it with corrugated paper cores to make corrugated cardboard boxes, which are used to package household appliances, daily necessities, textiles, stationery, and the outer packaging of Chinese and Western medicines.
[0003] Kraft paper is prone to bending at its edges and corners during production due to improper storage or collisions during transportation. Therefore, it is necessary to use leveling equipment to flatten the kraft paper.
[0004] Most existing kraft paper leveling equipment uses pressure plates or rollers to directly flatten the kraft paper. However, this operation can easily press down the bent parts at the corners of the kraft paper, resulting in failure to level the kraft paper. Utility Model Content

[0029] like Figures 1-5As shown, this utility model provides a kraft paper leveling device, including a belt conveyor 10 and a control cabinet. The belt conveyor 10 includes a frame 11 and a conveyor belt 12. The above-mentioned contents are all prior art, and the specific structure will not be described in detail here. This device also includes a support 20, a sliding component 30, and a pressing component 40.
[0030] The bracket 20 is fixedly installed on the frame 11.
[0031] The sliding assembly 30 includes a crossbar 31, a sliding plate 32, a lead screw 33, and a first motor 34. The crossbar 31 is positioned laterally above the transmission belt, and both ends are fixedly connected to the bracket 20. The sliding plate 32 is mounted on the crossbar 31 and slidably connected to it. The lead screw 33 passes laterally through the sliding plate 32 and is threadedly connected to it. Both ends of the lead screw 33 are rotatably connected to the bracket 20, and the lead screw 33 remains parallel to the crossbar 31. The first motor 34 is fixedly mounted on the bracket 20 and electrically connected to the control cabinet. The first motor 34 controls the rotation of the lead screw 33.
[0032] The pressing assembly 40 includes a housing 41, a pressure roller 42, and a cylinder 43. The housing 41 is laterally positioned between the transmission belt and the slide plate 32, and a receiving groove 44 is formed at the bottom of the housing 41. The pressure roller 42 is disposed within the receiving groove 44, and both ends are rotatably connected to the housing 41. The cylinder 43 is longitudinally positioned, with its cylinder body fixedly connected to the slide plate 32. The piston rod of the cylinder 43 passes through the slide plate 32 and is fixedly connected to the housing 41. The cylinder 43 is used to control the up-and-down movement of the housing 41. The bottom of the outer walls on both sides of the housing 41 forms downwardly sloping and outwardly extending guide surfaces.
[0033] In the initial state, cylinder 43 is in the retracted state, and pressure roller 42 is located above conveyor belt 12, which is used to transport kraft paper 80.
[0034] The specific working process of this equipment is as follows: First, the control cabinet starts the belt conveyor 10, and the conveyor belt 12 transports the kraft paper 80. When the middle of the kraft paper 80 reaches directly under the pressure roller 42, the conveyor belt 12 stops running. Then, the control cabinet starts the cylinder 43, and the piston rod of the cylinder 43 extends until the pressure roller 42 presses onto the kraft paper 80. Next, the control cabinet starts the first motor 34, which drives the lead screw to rotate. Under the action of the crossbar 31, the slide plate 32 drives the pressing component 40 to reciprocate, and the pressure roller 42 rolls back and forth on the kraft paper 80, thereby crushing and flattening the kraft paper 80. Finally, the control cabinet resets the equipment to the initial state, and the conveyor belt 12 continues to run until the next sheet of kraft paper 80 moves directly under the pressure roller 42, at which point the equipment continues to flatten the next sheet of kraft paper 80.
[0035] It is worth noting that during the rolling process of the pressure roller 42, the guide surface on the housing 41 plays a scooping role. The guide surface will first lift up the bent part of the kraft paper 80 at the corner and then press it down, thus achieving a better flatness.
[0036] In one embodiment, the pressing assembly 40 further includes a vertical rod 45 that passes longitudinally through the slide plate 32 and is slidably connected to the slide plate 32, and the vertical rod 45 is fixedly connected to the housing 41.
[0037] The upright 45 guides the up-and-down movement of the housing 41 and the pressure roller 42, making their up-and-down movement more stable.
[0038] In one embodiment, the pressure regulating component 50 is further included, which includes a guide rod 51, a slider 52, a spring 53, a permanent magnet 54, and an electromagnet 55.
[0039] A guide rod 51 is fixedly mounted longitudinally on the housing 41. A slider 52 is mounted on the guide rod 51 and slidably connected to it, while the slider 52 is rotatably connected to the pressure roller 42. A spring 53 is sleeved on the guide rod 51, with its first end fixedly connected to the slider 52 and its second end fixedly connected to the housing 41. The spring 53 causes the slider 52 to tend to move downwards. A permanent magnet 54 and an electromagnet 55 are arranged opposite each other, and are respectively fixedly mounted on the slider 52 and the housing 41. The electromagnet 55 is electrically connected to the control cabinet.
[0040] In the initial state, the electromagnet 55 is energized. At this time, the permanent magnet 54 and the electromagnet 55 are attracted together. Most of the pressure roller 42 is hidden in the receiving groove 44, and only a small part of the pressure roller 42 is exposed from the receiving groove 44.
[0041] After the piston rod of cylinder 43 extends, under the action of sliding component 30, pressure roller 42 will roll back and forth on kraft paper 80, thereby crushing and flattening kraft paper 80. Since most of pressure roller 42 is in receiving groove 44 at this time, the guide surface is very close to kraft paper 80, which can better pick up the bent parts at the corners of kraft paper 80.
[0042] After the pressure roller 42 has been rolling and leveling for a certain period of time, the control cabinet cuts off the power to the electromagnet 55. At this time, under the action of the spring 53, the pressure roller 42 will apply greater pressure to the kraft paper 80, thereby improving the flatness of the kraft paper 80.
[0043] In this embodiment, there are two pressure regulating components 50, which are located at both ends of the housing 41, further improving the stability of the device during operation.
[0044] In one embodiment, it further includes a limiting component 60 and a driving component 70.
[0045] The limiting component 60 includes a limiting frame 61 and a vertical rod 62. A limiting groove 63 is formed in the limiting frame 61, which is longitudinally penetrating and adapts to the kraft paper 80. The vertical rod 62 passes through the frame 11 and is slidably connected to the frame 11, and is fixedly connected to the limiting frame 61.
[0046] The drive assembly 70 is used to control the vertical movement of the vertical rod 62.
[0047] In the initial state, the limiting frame 61 is located between the pressure roller 42 and the conveyor belt 12, and the thickness of the limiting frame 61 is less than the thickness of the kraft paper 80.
[0048] Before cylinder 43 starts, drive assembly 70 first controls vertical rod 62 to move downwards. Vertical rod 62 drives limit frame 61 to move downwards until limit groove 63 frames kraft paper 80. In this way, when pressure roller 42 rolls, kraft paper 80 will not move, further improving the flatness of the equipment.
[0049] After the leveling work is completed, the drive component 70 can then control the vertical rod 62 and the limit frame 61 to reset.
[0050] In one embodiment, the drive assembly 70 includes a connecting rod 71, a rotating rod 72, and a second motor 73. The connecting rod 71 is fixedly mounted laterally on the vertical rod 62. The first end of the rotating rod 72 is rotatably connected to the frame 11, and the second end of the rotating rod 72 contacts the bottom of the connecting rod 71. The second motor 73 is fixedly mounted on the frame 11 and electrically connected to the control cabinet. The second motor 73 is used to control the rotation of the first end of the rotating rod 72.
[0051] In the initial state, the second end of the rotating rod 72 is in contact with the bottom of the connecting rod 71, and at this time the limiting frame 61 is located between the pressure roller 42 and the conveyor belt 12.
[0052] Before cylinder 43 starts, the control cabinet controls the second motor 73 to start. The second motor 73 drives the first end of the rotating rod 72 to rotate, and the second end of the rotating rod 72 will swing downward until the limit groove 63 frames the kraft paper 80.
[0053] After the leveling work is completed, the control cabinet controls the second motor 73 to start. The second motor 73 drives the first end of the rotating rod 72 to reverse, and the second end of the rotating rod 72 will swing upward, thereby lifting the connecting rod 71 and the limit frame 61 upward, so that the limit frame 61 returns to its initial state.
[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
