Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, specifically to a single-person paper-lifting device for Xuan paper. Background Technology

[0002] Xuan paper, a traditional Chinese paper for calligraphy and painting, is produced through a series of processes including steaming, pulping, scooping, pressing, drying, and paper cutting. For the scooping process, the paper-scooping equipment mainly consists of a screen frame and a paper-scooping screen laid flat on the frame. During operation, one or two operators hold the screen frame and swing it back and forth in the pulp tank to scoop the pulp evenly onto the surface of the paper-scooping screen. Then, the screen frame is lifted out of the pulp tank, and after initial drainage, the paper-scooping screen is separated from the frame and its pulp-side is placed on top of the stacked wet paper to peel off the pulp layer. This process is repeated to obtain layers of stacked wet paper.

[0003] A paper-retrieving device (document number CN103741535B) discloses a technical solution for paper retrieval. The device includes a frame composed of rods and pipes. Support rods are laid flat on the frame to form a grid-like frame surface. A paper-retrieval bamboo curtain is laid flat on the grid-like frame surface inside the frame. A pressing mechanism is provided on the frame to fix the edge of the paper-retrieval bamboo curtain. A handle is provided on the frame for the operator to hold. The paper-retrieval device disclosed in the above document requires manual operation of the pressing mechanism to press the bamboo curtain after it is placed on the frame. Then, the operator holds the handle to perform the paper-retrieval operation. Because the pressing mechanism needs to be operated to press the bamboo curtain, the operation of the paper-retrieval device is cumbersome. At the same time, when holding the handle to perform the paper-retrieval operation, both hands have to bear the weight of the entire device, which is also laborious. Utility Model Content

[0004] The purpose of this invention is to provide a simple and labor-saving single-person paper-retrieving device for Xuan paper.

[0005] This utility model can be achieved through the following technical solution: a single-person paper-feeding device for Xuan paper, wherein a pair of parallel transverse frame rods of the paper-feeding frame are parallel to one side of the paper-feeding trough, and there are recessed parts between the two ends of the longitudinal frame rods and the transverse frame rods to accommodate the ends of the curtain rods of the paper-feeding curtain, and the two ends of the parallel and spaced longitudinal support rods are connected to the transverse frame rods and the upper rod surfaces of the longitudinal support rods are coplanar, and the upper end of the hanging rope is connected to the top of the paper-feeding trough and the lower end of the hanging rope is connected to the inner section of the longitudinal frame.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] By placing the ends of the two side rods of the paper-retrieving curtain into corresponding recesses, the recesses restrict the paper-retrieving curtain from sliding along the longitudinal support rod length direction, eliminating the need for manual clamping and fixing of the paper-retrieving curtain, thus simplifying the paper-retrieving process. Moreover, by suspending the paper-retrieving frame with ropes, the ropes bear most of the weight of the paper-retrieving frame, and the operator only needs to apply a small force to maintain the balance of the paper-retrieving frame, thereby reducing the operator's workload and improving the efficiency of paper retrieval.

[0015] Please see Figure 1-7 As shown, a single-person paper-feeding device for Xuan paper includes a paper-feeding frame 30 with a pair of parallel transverse frame rods 31 parallel to one side of the paper-feeding trough 10. The two ends of the longitudinal frame rods 32 are located between the transverse frame rods 31 and the ends of the curtain rods 41 that accommodate the paper-feeding curtain 40. The two ends of the parallel and spaced longitudinal support rods 33 are connected to the transverse frame rods 31, and the upper rod surfaces of the longitudinal support rods 33 are coplanar. The upper end of the hanging rope 20 is connected above the paper-feeding trough 10, and the lower end of the hanging rope 20 is connected to the inner section of the longitudinal frame 32.

[0016] During paper retrieval, the operator stands on the operating side outside the paper retrieval trough 10 and places the ends of the two curtain rods 41 of the paper retrieval curtain 40 into the corresponding recesses 311. The paper curtain part of the paper retrieval curtain 40 is supported by the upper rod surface of the longitudinal support rod 33, eliminating the need for manual clamping and fixing of the paper retrieval curtain 40, thus simplifying the paper retrieval process. In addition, the paper retrieval frame 30 is hoisted by the hoisting rope 20, which bears most of the weight of the paper retrieval frame 30. The operator only needs to apply a small force to maintain the balance of the paper retrieval frame 30, thereby reducing the operator's workload and improving the efficiency of paper retrieval. After retrieval, the paper retrieval curtain 40 is removed from the upper surface of the paper retrieval frame 30, and the wet paper on its surface is placed on the designated work station.

[0017] The upper surfaces of the longitudinal support rods 33 are lower than the upper surfaces of the longitudinal frame side rods 32. This arrangement ensures that the ends of the curtain side rods 41 of the paper-retrieving curtain 40 can be placed in the recessed portion 311, so that the recessed portion 311 can restrict the paper-retrieving curtain 40 from sliding along the length direction of the longitudinal support rods 33, thereby preventing the paper-retrieving curtain 40 from detaching from the surface of the paper-retrieving frame 30 during the paper-retrieving process.

[0018] The longitudinal frame rod 32 is connected to a lifting lug 211. The line connecting the two lifting lugs 211 is parallel to the transverse frame rod 31, and the distance between the line connecting the lifting lugs 211 and the transverse frame rod 31 on the operating side is greater than the distance between the line connecting the lifting lugs 211 and the transverse frame rod 31 on the opposite side of the operating side. This arrangement allows for a significant reduction in the force applied to the transverse frame rod 31 on the operating side when maintaining the balance of the paper-retrieving frame 30, thereby achieving the purpose of saving effort. On the other hand, when the transverse frame rod 31 on the operating side is placed on the support plate 53, it can provide support for the paper-retrieving frame 30, preventing the paper-retrieving frame 30 from tipping over in the direction opposite to the operating side.

[0019] The bottom of the longitudinal frame rod 32 is connected to a hanging rod 21, and the rod segments extending to the outside of the longitudinal frame rod 32 at both ends of the hanging rod 21 form a lifting lug 211; the hanging rod 21 is used to support the paper-retrieving frame 30, so that the force applied by the two hanging ropes 20 to the two longitudinal frame rods 32 is evenly distributed on the hanging rod 21.

[0020] Each of the two lifting lugs 211 is equipped with a lifting ring 22, and the lower ends of the two lifting ropes 20 are connected to hooks 23, with the hooks of the hooks 23 connected to the lifting rings 22. The hooks 23 and the lifting rings 22 are used to connect the lifting ropes 20 and the lifting lugs 211, which facilitates the installation and disassembly of the lifting ropes 20 and the lifting lugs 211.

[0021] In the above, the line parallel to the transverse frame edge rod 31 and passing through the center of mass of the paper-retrieving frame 30 is denoted as the center of mass line M. The distance between the transverse frame edge rod 31 on the operating side and the center of mass line M is denoted as L1, and the distance between the lifting rod 21 and the center of mass line M is denoted as L2. L1 occupies a certain percentage of L2. On the one hand, the lever arm length L1 on the operating side is greater than the lever arm L2 on the other side, so as to minimize the force applied to the transverse frame bar 31 on the operating side and keep the frame surface of the paper scooping frame 30 in a flat state; on the other hand, it also makes the distance L3 between the transverse frame bar 31 on the opposite side of the operating side and the center line M of mass appropriate, so that the paper scooping frame 30 can scoop pulp from the position on the opposite side of the operating side.

[0022] A support frame 51 is installed at the top of the wall of the paper-feeding trough 10 on the operating side. A connecting block 52 is fixed to the side of the support frame 51 facing the paper-feeding frame 30. A support plate 53 is fixed to the side of the connecting block 52 facing the paper-feeding frame 30. When the transverse frame bar 31 on the operating side rests on the support plate 53, the frame surface of the paper-feeding frame 30 is flat. After the paper-feeding frame 30 scoops out the pulp from the paper-feeding trough 10, it needs to be drained briefly above the paper-feeding trough 10. With the push of the operator, the transverse frame bar 31 on the operating side rests on the support plate 53. On the support plate 53, the two hanging ropes 20 and the support plate 53 support the paper-collecting frame 30, so that the frame surface of the paper-collecting frame 30 is in a flat state, which can ensure that the pulp thickness at the top of the paper-collecting curtain 40 is basically consistent. At the same time, the water in the paper-collecting frame 30 flows into the paper-collecting trough 10 through the paper-collecting curtain 40. In this application, the support frame 51 and the connecting block 52 and support plate 53 provided thereon are referred to as a set of support members. Preferably, there are two sets of support members, and the two sets of support members are symmetrically arranged about the center of the horizontal frame rod 31.

[0023] The support frame 51 is in an inverted U-shape, and the two plates on opposite sides of the support frame 51 are engaged with the upper edge of the trough wall of the paper trough 10. The shape of the support frame 51 makes it easy to install the support frame 51 onto the upper edge of the trough wall of the paper trough 10, and also makes it easy to remove.

[0024] The support plate 53 is an L-shaped plate with two perpendicular sides. The vertical plate of the support plate 53 is fixed on the plate surface of the connecting block 52, and the horizontal plate of the support plate 53 is parallel to the top surface of the trough wall of the paper trough 10. The connection between the support plate 53 and the connecting block 52 is achieved by using the vertical plate of the support plate 53, which increases the area of ​​the connection part and helps to improve the stability of the connection.

[0025] The longitudinal support rod 33 is used to support the top cross section of the paper-collecting curtain 40, which gradually increases from top to bottom; this can reduce the contact area between the longitudinal support rod 33 and the paper-collecting curtain 40, thereby facilitating the flow of water from the bottom of the paper-collecting curtain 40 and accelerating the drainage speed.

[0026] The top surface of the longitudinal support rod 33 is provided with a circular thin steel rod 332. The thin steel rod 332 is aligned with the longitudinal support rod 33 in the same length direction. A connecting column 331 is connected to the bottom side of the thin steel rod 332. The lower end of the connecting column 331 is connected to the longitudinal support rod 33. The connecting columns 331 are spaced apart from each other. The thin steel rod 332 is used to support the paper-collecting curtain 40, which further reduces the contact area between the paper-collecting curtain 40 and the top of the longitudinal support rod 33. The distance between the longitudinal support rod 33 and the paper-collecting curtain 40 is also increased, which facilitates the rapid flow of pulp water above the paper-collecting curtain 40 during paper collection, thereby accelerating the drainage speed. By setting the thin steel rod 332 on the longitudinal support rod 33, the cross-sectional shape of the longitudinal support rod 33 can be simplified to a square cross-section, thereby reducing the processing cost of the longitudinal support rod 33 and simplifying the connection structure with the two transverse frame rods 31.

[0027] In this application, the top of the hoisting rope 20 can be connected to a crossbeam above the paper trough 10, and the crossbeam is fixed to the wall of the factory building.
