Technical Field

[0001] This utility model relates to the field of paperboard production technology, specifically a pressing device for composite paperboard production. Background Technology

[0002] Paperboard, also known as board paper, is a thick sheet of paper made from various pulps, composed of interwoven fibers. The difference between paperboard and regular paper is usually distinguished by basis weight and thickness; generally, paperboard with a basis weight exceeding 250 g / m³ is considered superior. 2 Paperboard with a thickness greater than 0.5mm is called paperboard. According to its use, it can be divided into packaging paperboard, industrial and technical paperboard, construction paperboard and printing and decoration paperboard.

[0003] In paperboard processing, a flattening process is required. However, in traditional flattening devices, before the paperboard is flattened, personnel need to manually feed the paperboard to the pressing part of the device. After the paperboard is flattened, it is then manually removed and replaced with the next set of paperboard to be flattened. Manual operation requires the hands to reach into the pressing part, which poses a safety hazard. Therefore, a pressing device for composite paperboard production is proposed. Utility Model Content

[0028] Example

[0029] Please see Figure 1-5 This utility model provides a technical solution: a pressing device for composite paperboard production, comprising...

[0030] Workbench 1, with mounting frame 2 installed on top of workbench 1, electric cylinder 3 installed on top of mounting frame 2, push rod of electric cylinder 3 passing through the top of mounting frame 2 and fixedly connected to pressure plate 5, with pushing components on both sides of pressure plate 5, and feeding components installed on the top of workbench 1 inside mounting frame 2.

[0031] By coordinating the pushing and feeding components, the safety of the device can be improved. The pushing component includes two fixed columns 9, which are respectively fixedly connected to both ends of the pressure plate 5. Each of the two fixed columns 9 has a guide groove 10 at its bottom, and one end of the guide groove 10 has an inclined surface 11. The feeding component includes two slide rails 6, a slide plate 7, and two L-shaped push columns 8. The two slide rails 6 are fixedly connected to the top of the worktable 1. The slide plate 7 is slidably connected to the top of the two slide rails 6 via two sliding grooves at its bottom. The two L-shaped push columns 8 are respectively fixedly connected to both ends of the slide plate 7 and are located below the two pressure plates 5. Rollers can be installed on the top of the L-shaped push columns 8. The wheel moves on the inclined plane 11, changing from sliding friction to rolling friction, which improves the service life of the L-shaped push column 8. The L-shaped push column 8 matches the guide groove 10. The top of the mounting frame 2 is provided with a through groove above the guide groove 10. The push rod of the electric cylinder 3 drives the pressure plate 5 to move and flatten the cardboard. During the movement of the pressure plate 5, the pressure plate 5 drives the fixed column 9 to move downward, so that the top of the L-shaped push column 8 is inserted into the interior of the guide groove 10 and abuts against the inclined plane 11, thereby pushing the L-shaped push column 8 to move backward. The L-shaped push column 8 then drives the slide plate 7 to move, so that the cardboard on the slide plate 7 moves to directly below the pressure plate 5, thus completing the feeding of the cardboard. There is no need for personnel to put their hands into the device to release the material.

[0032] To improve stability, several guide posts 4 are fixedly connected between the workbench 1 and the mounting frame 2. The pressure plate 5 is movably sleeved on the outside of the guide posts 4. The push rod of the electric cylinder 3 drives the pressure plate 5 to move on the outside of the guide posts 4. The guide posts 4 can ensure that the pressure plate 5 moves down smoothly.

[0033] To facilitate the handling of the flattened cardboard, a fixing block 12 is fixedly connected to the top rear side of the workbench 1. A first guide rod 13 is fixedly connected to one side of the fixing block 12. The first guide rod 13 is movably inserted into the interior of the slide plate 7. A first telescopic spring 14 is movably sleeved on the outer side of the first guide rod 13. The first telescopic spring 14 needs to be maintained and replaced regularly. One end of the first telescopic spring 14 is fixedly connected to one side of the fixing block 12, and the other end of the first telescopic spring 14 is fixedly connected to the rear side of the slide plate 7. During the movement of the slide plate 7, the first guide rod 13 moves inside the slide plate 7, and the first telescopic spring 14 is compressed under force. When the cardboard is flattened, it is reset by the push rod of the electric cylinder 3. The push rod of the electric cylinder 3 drives the fixing posts 9 on both sides of the pressure plate 5 away from the L-shaped push post 8. At this time, the first telescopic spring 14 pushes the slide plate 7 to move and reset on the slide rail 6, sending out the flattened cardboard.

[0034] To limit the movement of multiple cardboard pieces, the pressure plate 5 has grooves 15 on each of its three sides. A second guide rod 16 is fixedly connected to the bottom of the groove 15. A positioning block 17 is movably sleeved on the outer side of the second guide rod 16. A second telescopic spring 18 is movably sleeved below the positioning block 17 on the second guide rod 16. The second telescopic spring 18 needs to be maintained and replaced regularly. One end of the second telescopic spring 18 is fixedly connected to the bottom of the positioning block 17, and the other end is fixedly connected to the bottom of the groove 15. When the composite cardboard needs to be flattened, multiple cardboard pieces are placed on top of the slide plate 7, so that the three sides of the cardboard pieces abut against the outer side of the positioning block 17, thereby positioning the cardboard pieces. During the pressing of the pressure plate 5, the positioning block 17 moves outside the second guide rod 16, and the second telescopic spring 18 is compressed. The positioning block 17 moves inside the groove 15 without affecting the flattening of the cardboard pieces. When the pressure plate 5 is removed from the cardboard pieces, the second telescopic spring 18 drives the positioning block 17 to reset, so as to facilitate the positioning of the cardboard pieces to be processed later.

[0035] Limiting blocks 19 are fixedly connected to both sides of the top of the workbench 1. The limiting blocks 19 are used to limit the position of the L-shaped push column 8. During the process of the first telescopic spring 14 pushing the slide plate 7 to move and reset on the slide rail 6, the limiting blocks 19 can limit the movement position of the L-shaped push column 8.

[0036] The working principle or structural principle is as follows: When it is necessary to flatten the composite paperboard, multiple paperboards are placed on top of the slide plate 7, so that the three sides of the paperboards abut against the outside of the positioning block 17, thereby positioning the paperboards. Then, the push rod of the electric cylinder 3 is extended by the switch group. The push rod of the electric cylinder 3 drives the pressure plate 5 to move outside of several guide columns 4, so that the pressure plate 5 abuts against the paperboard, thereby flattening the paperboard. During the movement of the pressure plate 5, the pressure plate 5 drives the fixed column 9 to move downward, so that the top of the L-shaped push column 8 is inserted into the inside of the guide groove 10 and abuts against the inclined surface 11, thereby pushing the L-shaped push column 8 to move backward. The L-shaped push column 8 then drives the slide plate 7 to move, so that the paperboard on the slide plate 7 moves to directly below the pressure plate 5, thus completing the feeding of the paperboard. It is not necessary for personnel to put their hands into the device to feed the material, which improves the safety of the device.

[0037] During the movement of the slide plate 7, the first guide rod 13 moves inside the slide plate 7, and the first telescopic spring 14 is compressed. When the cardboard is flattened, the push rod of the electric cylinder 3 is reset by the control of the switch group. The push rod of the electric cylinder 3 drives the fixed columns 9 on both sides of the pressure plate 5 away from the L-shaped push column 8. At this time, the first telescopic spring 14 pushes the slide plate 7 to move and reset on the slide rail 6, and the limiting block 19 can limit the movement position of the L-shaped push column 8. By sending out the flattened board, it is convenient for personnel to pick up, while ensuring the safety of personnel.
