Description

Technical Field

[0001] This utility model relates to the field of sulfur-free paper processing technology, specifically to a separation device for sulfur-free paper. Background Technology

[0002] Sulfur-free paper is widely used as an important insulating material in the production processes of flexible printed circuit boards (FPCs) and other electronics manufacturing industries. While sulfur-free paper possesses excellent insulating properties, friction between sheets is inevitable during transportation. Because sulfur-free paper is an excellent insulator, the static charge generated by this friction cannot be dissipated quickly enough, resulting in a significant accumulation on the paper surface.

[0003] Existing paper handling machines mostly lack effective solutions for electrostatic adsorption when separating sulfur-free paper. Some devices rely solely on simple mechanical separation methods, such as directly adsorbing the top layer of paper using suction cups. However, due to the strong electrostatic adsorption between the papers, the suction cups can easily pick up multiple sheets of paper at once, leading to inaccurate separation. Therefore, a separation device for sulfur-free paper is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a separation device for sulfur-free paper to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a separation device for sulfur-free paper, comprising a box body, wherein a placement groove is provided inside the box body, and sulfur-free paper is placed inside the placement groove;

[0006] The box body is connected to several support frames on both sides, and several saw teeth are fixed on one side of each support frame. A slot for inserting sulfur-free paper is provided between adjacent saw teeth.

[0007] An air jet frame is provided between adjacent support frames. A plurality of air outlets are provided on one side of the air jet frame. The air outlets are used to blow air into the gaps of the sulfur-free paper inserted into the slot.

[0008] The top four sides of the box are all fixed with baffle plates;

[0009] A connecting component is provided on one side of the box body, and the connecting component is used for the assembly and disassembly of the support frame;

[0010] The connecting assembly includes a protrusion and a sliding plate. Two sliding rods are fixed to the outside of the sliding plate, and a locking groove is provided on one side of the protrusion.

[0011] Preferably, the top of the box body is provided with a plurality of first limiting grooves, and the jet frame is adapted to the inner side of the first limiting grooves.

[0012] Preferably, the jet frame is connected to the box body by screws, and an air pipe is fixed on one side of the jet frame, which is connected to the air outlet.

[0013] Preferably, a second sliding groove is provided on the inner side of the box body, and the inner wall of the second sliding groove is provided with a plurality of first sliding grooves and second limiting grooves, and the first sliding grooves and the second limiting grooves are connected to each other.

[0014] Preferably, a screw is rotatably connected to one side of the slide plate, and a first nut and a second nut are threaded onto the outer side of the screw.

[0015] Preferably, the second nut is fixedly embedded in the inner side of the box, and the slide plate is slidably connected to the inner side of the second groove.

[0016] Preferably, a plurality of locking rods are fixed on one side of the slide rod. When the locking rod is inserted into the inner side of the locking groove, the support frame is in the installed state. When the locking rod leaves the inner side of the locking groove, the support frame is in the disassembled state.

[0017] Preferably, the protrusion is adapted to the inner side of the second limiting groove, and the protrusion is fixed to the bottom of the support frame.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0019] 1. By contacting the edge of the sulfur-free paper with the serrations fixed on one side of the support frame, the top layer of sulfur-free paper is partially pried up, disrupting the electrostatic adsorption between the papers. At the same time, air is blown into the gap of the pried-up sulfur-free paper through the air outlet, and the airflow further pushes apart the lower layer of paper that is electrostatically adsorbed, ensuring that the top layer of sulfur-free paper is completely separated from the lower layer. After the top layer of sulfur-free paper is completely separated from the lower layer, the baffle plate plays a physical blocking role, preventing the sulfur-free paper adsorbed during the shaking process from re-adhering to the lower layer of sulfur-free paper. At the same time, it disrupts the residual electrostatic adsorption between the papers. The suction cup connected to the push rod end of the paper suction lifting cylinder can successfully adsorb the separated single sheet of sulfur-free paper, avoiding the situation of adsorbing multiple sheets of paper. This reduces the occurrence of abnormal situations such as paper not separating, multiple sheets being picked up at once, or paper jams, thereby improving the operating efficiency of the equipment, enabling the equipment to operate more stably and efficiently, and ensuring production continuity.

[0020] 2. When the serrations on one side of the support frame are damaged and need to be replaced, loosen the first nut on the outside of the screw, turn the screw clockwise to drive the slide plate to slide in the second groove opened on the inside of the box, thereby causing several locking rods fixed on one side of the slide rod to leave the locking groove opened on the side of the protrusion. This allows the support frame to be easily switched from the installed state to the disassembled state. The operation process is clear and simple, making it convenient for staff to quickly carry out disassembly work. The disassembly and installation of the support frame does not require complicated tools or professional skills. Ordinary maintenance personnel can complete the operation, reducing the downtime of the equipment due to the replacement of parts. Attached Figure Description

[0030] Example

[0031] Please see Figure 1-5 This utility model provides a technical solution: a separation device for sulfur-free paper, including a box body 1, which is installed on the top of a lifting platform (not shown in the figure). The top of the box body 1 is equipped with a cylinder (not shown in the figure) for picking up sulfur-free paper. A suction cup (not shown in the figure) is connected to the push rod end of the cylinder. The suction cup moves downward under the push of the cylinder, thereby picking up the sulfur-free paper. The push rod end of the paper-picking lifting cylinder drives the suction cup downward, toward the stack of sulfur-free paper in the placement groove 6 inside the box body 1. Simultaneously, the lifting platform moves downward, so that the top of the stack of sulfur-free paper contacts the support frame 2. The box body 1 has a placement groove 6 inside, and sulfur-free paper is placed inside the placement groove 6.

[0032] The top of the box 1 has several first limiting grooves 3. The jet frame 4 is adapted to the inner side of the first limiting groove 3. The jet frame 4 is connected to the box 1 by screws. An air pipe 10 is fixed on one side of the jet frame 4. The air pipe 10 is connected to the air outlet 5.

[0033] Several support frames 2 are connected to both sides of the box body 1. Several serrations 21 are fixed on one side of each support frame 2, and slots 22 for inserting sulfur-free paper are provided between adjacent serrations 21. The serrations 21 on one side of the support frame 2 contact the edge of the sulfur-free paper. The sharp teeth of the serrations 21 insert into the gaps between the papers, breaking the electrostatic adsorption and causing the top layer of paper to be partially pried up. The slots 22 between adjacent serrations 21 allow the insertion of sulfur-free paper.

[0034] An air jet frame 4 is provided between adjacent support frames 2. Several air outlets 5 are opened on one side of the air jet frame 4, which are used to blow air into the gaps of the sulfur-free paper inserted into the slot 22. The air jet frame 4 blows air into the gaps of the sulfur-free paper inserted into the slot 22 through the air outlets 5 on one side. The airflow is introduced through the air pipe 10, and the air inlet of the air pipe 10 is connected to an air compressor to help push away the adsorbed paper. Baffle plates 7 are fixed around the top of the box body 1. The suction cup adsorbs the separated single sheet of sulfur-free paper under the push of the cylinder. Then the cylinder begins to rise. During the rise, the cylinder push rod reciprocates, causing the adsorbed sulfur-free paper to shake. At the same time, the baffle plates 7 around the top of the box body 1 act as physical barriers to prevent the adsorbed paper from sticking to the lower layer of paper due to static electricity, ensuring that only a single sheet of paper is lifted.

[0035] A connecting component 9 is provided on one side of the box body 1. The connecting component 9 is used for the assembly and disassembly of the support frame 2. The connecting component 9 includes a protrusion 94 and a sliding plate 98. Two sliding rods 97 are fixed on the outer side of the sliding plate 98. A locking groove 93 is provided on one side of the protrusion 94. A second sliding groove 99 is provided on the inner side of the box body 1. The inner wall of the second sliding groove 99 is provided with several first sliding grooves 96 and second limiting grooves 911. The first sliding grooves 96 and the second limiting grooves 911 are connected. Loosening the first nut 92 and rotating the screw 91 clockwise will cause the sliding plate 98 to slide in the second sliding groove 99 on the inner side of the box body 1. The sliding rods 97 on the outer side of the sliding plate 98 will move accordingly, causing the locking rods 95 fixed on the sliding rods 97 to leave the locking grooves 93 on the protrusion 94.

[0036] A screw 91 is rotatably connected to one side of the slide plate 98. A first nut 92 and a second nut 910 are threadedly connected to the outside of the screw 91. The second nut 910 is fixedly embedded in the inside of the box 1. The slide plate 98 is slidably connected to the inside of the second slide groove 99.

[0037] Several locking rods 95 are fixed on one side of the slide rod 97. When the locking rod 95 is inserted into the inner side of the locking groove 93, the support frame 2 is in the installed state. When the locking rod 95 leaves the inner side of the locking groove 93, the support frame 2 is in the disassembled state. The protrusion 94 is adapted to the inner side of the second limiting groove 911. The protrusion 94 is fixed to the bottom of the support frame 2. When the locking rod 95 is disengaged from the locking groove 93, the support frame 2 is in the disassembled state. The support frame 2 can be removed from the box 1. After replacement, the screw 91 is turned counterclockwise and the first nut 92 is tightened to fix it again.

[0038] Working principle: When the equipment is started, the paper-grabbing lifting cylinder responsible for paper gripping descends below the box 1 where the sulfur-free separation paper is fed. During the descent, the lifting platform connected to the box 1 moves down synchronously, so that the sulfur-free paper in the placement slot 6 inside the box 1 contacts the support frame 2 on both sides, preparing for the subsequent separation action.

[0039] As the lifting platform continues to descend, the serrations 21 fixed on one side of the support frame 2 come into contact with the edge of the sulfur-free paper. Under the action of the serrations 21, the sulfur-free paper is inserted between the slots 22, which breaks the electrostatic adsorption force between the papers and causes the top layer of sulfur-free paper to be partially pried up. The air outlet 5 moves synchronously with the serrations 21, and the air jet frame 4 installed between the adjacent support frames 2 starts the "blowing action". Air is blown into the gap of the sulfur-free paper pried up by the serrations 21 through the air outlet 5 opened on one side of the air jet frame 4. The airflow further pushes away the lower layer of paper that is electrostatically adsorbed, ensuring that the top layer of sulfur-free paper is completely separated from the lower layer of paper.

[0040] Once the top sheet of sulfur-free paper is completely separated from the bottom sheet, the suction cup connected to the push rod end of the paper suction lifting cylinder successfully absorbs the separated single sheet of sulfur-free paper. Then, the paper suction lifting cylinder begins to rise. During the rise of the paper suction lifting cylinder, its push rod end reciprocates, causing the absorbed sulfur-free paper to shake. At this time, the baffle plate 7 fixed around the top of the box 1 plays a physical blocking role. On the one hand, it prevents the absorbed sulfur-free paper from re-adhering to the bottom sheet of sulfur-free paper during the shaking process. On the other hand, it breaks the residual electrostatic adsorption force between the papers, avoiding the excess sulfur-free paper in the box 1 placement slot 6 from being "carried away" by static electricity when the paper suction lifting cylinder rises. This reduces abnormalities such as paper not being separated, multiple sheets being picked up at once, or paper jams, improves equipment operating efficiency, and reduces manpower for abnormal handling.

[0041] When the serration 21 on one side of the support frame 2 is damaged and needs to be replaced, loosen the first nut 92 on the outside of the screw 91 connected to the sliding plate 98 until the first nut 92 moves to the end of the screw 91 near the handwheel. Rotate the screw 91 clockwise. Since the second nut 910 connected to the screw 91 is fixedly embedded in the inside of the box 1, the rotating screw 91 drives the sliding plate 98 to slide in the second sliding groove 99 opened on the inside of the box 1. The two sliding rods 97 fixed on the outside of the sliding plate 98 move synchronously with the sliding plate 98, thereby driving the several locking rods 95 fixed on one side of the sliding rod 97 to leave the inside of the locking groove 93 opened on one side of the protrusion 94. At this time, the support frame 2 switches from the installed state to the disassembled state.

[0042] Since the protrusion 94 is adapted to the inner side of the second limiting groove 911 of the box body 1 and fixed to the bottom of the support frame 2, after the locking rod 95 is completely disengaged from the locking groove 93, the support frame 2 can be removed from both sides of the box body 1 to replace the damaged saw teeth 21. After the replacement is completed, the operation is reversed to reinstall the support frame 2, so that the locking rod 95 is inserted into the locking groove 93 again, the installation state of the support frame 2 is restored, and the first nut 92 is tightened to prevent the screw 91 from rotating loosely by using double nuts.

[0043] In summary, by having the serrations 21 fixed to one side of the support frame 2 contact the edge of the sulfur-free paper, the top layer of sulfur-free paper is partially pried up, disrupting the electrostatic adsorption between the papers. Simultaneously, the air outlet 5 blows air into the gaps of the pried-up sulfur-free paper, further pushing apart the electrostatically adsorbed lower layer of paper, ensuring that the top layer of sulfur-free paper is completely separated from the lower layer. After the top layer of sulfur-free paper is completely separated from the lower layer, the baffle plate 7 acts as a physical barrier, preventing the sulfur-free paper adsorbed during the shaking process from re-adhering to the lower layer, while also disrupting the residual electrostatic adsorption between the papers. The suction cup connected to the push rod end of the paper suction lifting cylinder can successfully adsorb the separated single sheet of sulfur-free paper, avoiding the situation of adsorbing multiple sheets of paper, reducing the occurrence of abnormal situations such as paper not separating, multiple sheets being picked up at once, or paper jams, thereby improving the operating efficiency of the equipment, enabling the equipment to operate more stably and efficiently, and ensuring production continuity.

[0044] When the serration 21 on one side of the support frame 2 is damaged and needs to be replaced, the first nut 92 on the outside of the screw 91 is loosened, and the screw 91 is rotated clockwise to drive the slide plate 98 to slide in the second slide groove 99 opened on the inside of the box 1. This causes several locking rods 95 fixed on one side of the slide rod 97 to leave the locking groove 93 opened on the side of the protrusion 94, which can easily switch the support frame 2 from the installed state to the disassembled state. The operation process is clear and simple, which makes it convenient for staff to quickly carry out disassembly work. The disassembly and installation of the support frame 2 does not require complicated tools and professional skills. Ordinary maintenance personnel can complete the operation, reducing the downtime of the equipment due to the replacement of parts.
