Description

Technical Field

[0001] This utility model relates to the field of paperboard production technology, specifically to a paperboard flipping and feeding structure. Background Technology

[0002] Paperboard, also known as board paper, is a thick sheet of paper made from various pulps, composed of interwoven fibers. The distinction between paperboard and paper is usually based on basis weight and thickness. Generally, paper with a basis weight exceeding 250 g / m² and a thickness greater than 0.5 mm is called paperboard. Alternatively, paper with a thickness greater than 0.1 mm is generally called paperboard. Generally, a basis weight less than 250 g / m² is considered paper, while a basis weight of 250 g / m² or higher is considered paperboard.

[0003] When paperboard is processed, it needs to be aligned and conveyed. However, depending on the specific processing requirements, it is sometimes necessary to flip or turn the paperboard over during conveying. Traditional paperboard feeding structures do not have an automatic flipping mechanism, so manual flipping is required during the paperboard conveying process. Manual flipping requires a certain amount of human resources, which increases the production cost of paperboard and reduces the economic benefits of enterprises. Therefore, this utility model proposes a paper feeding structure that can flip the paperboard. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a cardboard flipping and feeding structure, including a first feeding platform 1, a plurality of evenly distributed first feeding rollers 3 are rotatably mounted on the upper surface of the first feeding platform 1 through a first-stage bearing 2, a second feeding platform 4 is provided at the tail end of the first feeding platform 1, a plurality of evenly distributed second feeding rollers 6 are rotatably mounted on the upper surface of the second feeding platform 4 through a second-stage bearing 5, and the height of the first feeding platform 1 is higher than that of the second feeding platform 4.

[0024] In this way, the first paper feeding table 1 can rely on the first paper feeding roller 3 to feed the paperboard into the second paper feeding table 4, ensuring normal paperboard conveying operation;

[0025] A support plate 8 is fixedly installed at the lower front end of the No. 2 paper feeding table 4. A flipping component 7 is fixedly installed on the support plate 8. An upper support column 9 is fixedly installed on the upper front surface of the support plate 8. The upper support column 9 is fixedly connected to the lower surface of the No. 1 paper feeding table 1.

[0026] In this embodiment, the flipping assembly 7 includes a lower base plate 701, which is fixedly installed on the upper surface of the support plate 8 by fixing bolts. A guide member 702 is fixedly installed on the upper surface of the lower base plate 701. A guide groove is provided inside the guide member 702. A threaded screw 703 is rotatably installed in the guide groove of the guide member 702 through a bearing.

[0027] Among them, the threaded screw 703 is a positive and negative threaded screw 703, and a threaded seat 704 is fitted on both the positive and negative threads of the threaded screw 703, and the threaded seat 704 is threadedly connected to the threaded screw 703.

[0028] Furthermore, in order to drive the threaded screw 703 to rotate manually, a knob 709 is fixedly connected to one end of the threaded screw 703, and the outer wall of the knob 709 is provided with anti-slip serrations.

[0029] This structural design allows for manual rotation via a knob 709. When the knob 709 is rotated, it drives the threaded screw 703 to rotate synchronously. Since the threaded screw 703 is a forward and reverse threaded screw, when the threaded screw 703 rotates, the two threaded seats 704 on it will move relative to each other, i.e., move away from or move closer to each other (this effect depends on the forward and reverse rotation of the threaded screw 703). In this way, the relative movement of the threaded seats 704 drives the relative movement of the structural assembly on them.

[0030] In this embodiment, an upper fixing plate 705 is fixedly installed on the upper surface of both threaded seats 704. A pneumatic cylinder 706 is fixedly installed on the upper surface of the upper fixing plate 705 by fixing bolts. A pneumatic rod 707 is telescopically connected to the top output end of the pneumatic cylinder 706.

[0031] Furthermore, a flip hook 708 is fixedly installed at the top of the pneumatic rod 707;

[0032] In actual use, during the process of feeding the cardboard from the first paper feeder 1 to the second paper feeder 4, when the cardboard reaches the end of the first paper feeder 1, it will be blocked by the flipping hook 708, as detailed in the instruction manual. Figure 1As shown, the pneumatic cylinder 706 drives the pneumatic rod 707 to retract. When the pneumatic rod 707 retracts, the flipping hook 708 at its upper end descends. As the flipping hook 708 descends, it presses down on one end of the cardboard, causing the other end of the cardboard to tilt upwards. During the continuous downward pressure, the cardboard tilts and flips, thus performing a flipping process. The flipped cardboard falls onto the second paper feeding table 4. The second paper feeding table 4 can then perform secondary production conveying of the flipped and turned cardboard, thereby completing the cardboard conveying and flipping operation of this utility model.

[0033] In this embodiment, lower support legs 10 are fixedly installed at the four corners of the bottom of both the first paper feeding platform 1 and the second paper feeding platform 4, and the lower support legs 10 at the bottom of the first paper feeding platform 1 and the second paper feeding platform 4 are on the same horizontal plane.

[0034] Working principle: When this utility model is in use, the cardboard enters from one end of the first paper feeding table 1. The cardboard can be rolled and conveyed by the first-stage paper feeding roller 3 on the first paper feeding table 1, so as to convey the cardboard to one end of the second paper feeding table 4, ensuring normal cardboard conveying.

[0035] During the process of feeding the cardboard from paper feeder 1 to paper feeder 4, when the cardboard reaches the end of paper feeder 1, it will be blocked by the flip hook 708, as detailed in the instruction manual. Figure 1 As shown, the pneumatic cylinder 706 can drive the pneumatic rod 707 to retract. When the pneumatic rod 707 retracts, the flipping hook 708 at its upper end will descend. When the flipping hook 708 descends, it will press down on one end of the cardboard, so that one end of the cardboard is subjected to downward pressure. At this time, the other end of the cardboard will be lifted. During the continuous pressing process, the cardboard will be lifted and flipped, thus performing the flipping process. The flipped cardboard falls onto the second paper feeding table 4. The second paper feeding table 4 can perform secondary production conveying of the flipped and turned cardboard, thus completing the cardboard conveying and flipping work of this utility model.

[0036] Meanwhile, this utility model can be manually rotated via the knob 709. When the knob 709 is rotated, it will drive the threaded screw 703 to rotate synchronously. Since the threaded screw 703 is a forward and reverse threaded screw, when the threaded screw 703 is rotated, the two threaded seats 704 on it will move relative to each other, that is, move away from each other or move closer to each other (this effect depends on the forward and reverse rotation of the threaded screw 703). In this way, the relative movement of the threaded seats 704 drives the flipping hooks 708 on them to move relative to each other, thereby completing the dynamic adjustment of the distance between the two flipping hooks 708.

[0037] In summary, the cardboard flipping and feeding structure of this utility model, through the coordinated use of the flipping components, can automatically complete the flipping and turning of the cardboard during the feeding process, thus achieving the practical effect of automated cardboard conveying and turning. It eliminates the need for manual turning, effectively reducing the input cost of human resources by replacing manual turning with a machine, thereby reducing the overall production cost of cardboard and increasing the economic benefits of the production enterprise.

[0038] Meanwhile, the flipping hooks of this utility model can move relative to each other under the action of the forward and reverse thread drive structure, thereby changing the distance between the two flipping hooks. This provides a practical effect of dynamic adjustment of the flipping hook distance. By adjusting the distance between the two flipping hooks, it can be used for flipping and conveying cardboard of different widths, effectively improving the applicable range of structural dimensions and reducing usage limitations. It can be dynamically adjusted according to different cardboard widths, making it more practical and flexible in structural adjustment. Moreover, the overall structure is simple, and the manufacturing and maintenance costs are low, making it suitable for widespread use.

[0039] It will be apparent to those skilled in the art that this invention 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 essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
