Description

Technical Field

[0001] This application relates to the field of Xuan paper manufacturing, specifically to a device for removing slag from Xuan paper blanks. Background Technology

[0002] In the process of making Xuan paper, rice straw, after removing the ears, nodes, and withered leaves, needs to be bundled into small bundles and then into larger bundles. These bundles are then soaked in a pool of water containing lime. The lime water thoroughly soaks and softens the rice straw, increasing its fiber content and thus improving the quality of the finished Xuan paper. After soaking for a period of time, the rice straw is taken out and dried. Once dried, it is bundled into bundles called straw embryos. At this stage, the straw embryos contain a large amount of lime residue and ash residue from the rice straw itself. Therefore, the straw embryos contain a lot of dust and residue, which needs to be cleaned before they can be used in the next production stage. The traditional cleaning process requires manual beating of the straw embryos with a whip to knock off the dust inside. The straw embryos are then placed on a sieve and shaken to remove the fallen dust. The entire manual cleaning process is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a straw removal device for Xuan paper making, which removes dust adhering to the straw, saves manpower, and improves the production efficiency of Xuan paper.

[0004] This utility model provides the following technical solution: a slag removal device for Xuan paper blanks, characterized in that: two side plates arranged in parallel and opposite directions are vertically arranged, the perimeter of the screen is square and matches the space between the two side plates, the edges of the screen on the side of the side plate are arranged at the same height in the middle of the vertical direction of the side plate, the edges of the screen perpendicular to the side plate are located at the vertically arranged edges of the side plate, a belt is arranged at the upper open part enclosed by the side plates, a feeding rod or plate is arranged on the belt, the belt is wound around the power roller and the reversing roller, and the belt surface is arranged parallel to the screen plate surface as a whole.

[0005] In the above technical solution, the power roller drives the belt to circulate between the power roller and the reversing roller. The material-pushing rod plate on the lower section of the belt between the power roller and the reversing roller extends downward and pushes the straw on the screen as the belt moves. As the straw moves from the upstream end to the downstream end on the screen, the ash and slag attached to the straw fall out of the grid holes on the screen. The material-pushing rod plate on the belt pushes the straw and also applies a teasing effect to the straw. The continuous change in the posture and position of the straw during the conveying process from upstream to downstream improves the efficiency of ash and slag leakage. Moreover, the straw conveying and ash removal tasks can be completed without the screen plate surface moving from upstream to downstream. Attached Figure Description

[0013] This application provides a device for removing residue from Xuan paper blanks, combined with... Figure 1 , 2 As shown in Figures 3 and 4, the two side plates 10 are arranged vertically with their surfaces parallel to each other. The screen 20 is square around its perimeter, which matches the space between the two side plates 10. The edges of the screen 20 located on the side of the side plate 10 are arranged at the same height in the middle of the vertical direction of the side plate 10. The edges of the screen 20 perpendicular to the side plate 10 are located at the vertically arranged edges of the side plate 10. A belt 30 is arranged at the upper open area enclosed by the side plates 10. A material-pulling rod or plate 31 is arranged on the belt 30. The belt 30 is wound around the power roller 32 and the reversing roller 33. The belt surface of the belt 30 is arranged parallel to the surface of the screen 20.

[0014] In the above scheme, the two side plates 10, the screen 20, and the belt 30 form a grass conveying channel. The grass is placed on the screen 20 and moved from upstream to downstream by the push rods or plates 31 arranged on the belt 30. During the grass displacement, the ash and slag attached to and mixed with the grass fall through the grid holes on the screen 20. The relatively closed channel formed by the side plates 10 and the belt 30 effectively restrains the dust phenomenon caused by ash and slag. By using the push rods or plates 31 arranged on the belt 30 to push the grass, the grass posture is changed, which improves the efficiency of dust removal. At the same time, the grass is conveyed from upstream to downstream. This avoids the scheme of conveying grass by the linear displacement of the screen 20. If the grass is conveyed by the linear displacement of the screen 20, a transmission mechanism is usually required for the screen 20. In environments with extremely high dust, the service life of the transmission mechanism, such as the chain drive mechanism, is limited, and the maintenance cost and workload cannot be controlled.

[0015] The structure formed by the two side plates 10 and the screen 20 has an H-shaped vertical cross-section, which is perpendicular to the surface of the side plates 10. By adopting this scheme, the upper area bounded by the screen 20 forms a feed conveying channel, and the lower area serves as an ash collection area, effectively preventing the ash from scattering during its fall.

[0016] like Figure 1 , 2 As shown, the two side plates 10 are supported on the foundation by elastic supports 40, and a vibration unit 50 is provided on the side plates 10. The two side plates 10 are respectively connected to the two elastic supports 40. When the vibration unit 50 vibrates the side plates 10, the side plates 10, grid 20 and belt 30 supported by the elastic supports 60 vibrate within an appropriate amplitude range in multiple degrees of freedom, which is beneficial to the displacement of the grass and the change of the grass posture. Under the action of the push rod or plate 31 arranged on the belt 30, the frequency and amplitude of posture change are increased, which further improves the efficiency of dust removal. In addition, when the side plates 10 and the screen 20 vibrate, their vibration direction includes up and down, left and right, front and back, and even rotation, which is also beneficial to the detachment of grass stems inserted or stuck in the grid holes of the screen 20.

[0017] like Figure 1 , 2 As shown in Figure 3, the two side plates 10 are rectangular plates with their short sides arranged vertically. The perimeter of the screen 20 is rectangular, and the length direction of the screen 20 is consistent with the length direction of the side plates 10. The upper half of the two side plates 10 has an external flange 11. The power roller 32 and the reversing roller 33 are rotatably supported by the power roller bearing seat 321 and the reversing roller bearing seat 331, respectively. The power roller bearing seat 321 and the reversing roller bearing seat 331 are set on the flange 11.

[0018] The above solution involves fixing the belt 30 on the side plate 10, which ensures that the positional relationship between the belt 30 and the screen 20 is fixed. This avoids the situation where the material-pulling rod or plate 31 cannot reach the grass due to a sudden increase in the gap between the belt 30 and the screen 20, and ensures that the material-pulling rod or plate 31 can effectively pry or pull the grass.

[0019] like Figure 2 As shown, the two ends of the screen 20 along its length are arranged at the same height or at different heights.

[0020] Preferably, due to the soft nature of the forage, the presence of ash and slag on it, and the evenly distributed grid holes of 6-7 cm in length on the screen 20, it is difficult to move the forage on the screen 20 by simply relying on the feeding rod or plate 31. The screen 20 is inclined at both ends, making it easy and quick to move the forage by the feeding rod or plate 11. In addition, some of the ash and slag retained on the screen 20 will be shaken off the screen 20 with the vibration of the screen 20, thus preventing the forage from adhering to the screen 20 during the downstream transportation process.

[0021] like Figure 1 , 4 As shown in Figure 5, one end of the power roller 32 is connected to a driven pulley 42, and a first transmission belt 411 is provided between the driving pulley 41 connected to the first motor 40 which is mounted on the foundation and the driven pulley 42.

[0022] The first motor 40 is fixed to the ground and connected to the drive pulley 41 to drive its rotation. The power roller 32 and the first motor 40 use a belt drive mechanism to transmit torque. Since the transmission belt has appropriate elasticity, it can meet the need for the constantly changing tension of the first transmission belt 411 when the position of the power roller 32 changes. As long as the first transmission belt 411 has an appropriate coverage angle range with the drive pulley 41 and the driven pulley 42, the rotation of the power roller 32 can be reliably driven. This avoids the vibration of the side plate 10, the screen 20 and the belt 30 as a whole, and also avoids the adverse result of setting the first motor 40 on the side plate 10 and vibrating synchronously with it.

[0023] like Figure 3 , 6 As shown, the excitation unit 50 includes a second motor 51 mounted on the foundation. A second transmission belt 521 is wound around a power pulley 52 connected to the motor shaft of the second motor 51 and a follower pulley 53. The follower pulley 53 and an eccentric wheel 54 are connected to the excitation wheel shaft 56. The rotation axis of the eccentric wheel 54 is eccentrically arranged with respect to the center of mass of the eccentric wheel 54. One end of the excitation wheel shaft 56 is rotatably supported by an excitation bearing seat 55. The excitation bearing seat 55 is connected to the outer plate surface of the side plate 10 on one side.

[0024] The second motor 51 is fixed to the ground foundation. The output torque of the motor shaft of the second motor 51 drives the power pulley 52 to rotate. Through the belt drive mechanism consisting of the power pulley 52, the second transmission belt 521, and the follower pulley 53, the eccentric wheel 54 rotates around the axis of the excitation wheel shaft 56. Due to the distance between the center of mass of the eccentric wheel 54 and the axis of the excitation wheel shaft 56, when the eccentric wheel 54 rotates, vibration is applied to the side plate 10 through the excitation wheel shaft 56 and the excitation bearing seat 55, thereby achieving the overall vibration of the side plate 10, the screen 20, and the belt 30. Preferably, as... Figure 4As shown, the first transmission belt 411 and the second transmission belt 521 are trapezoidal V-belts. When the driving pulley 41 and the driven pulley 42 are in a position far apart or close together, the first transmission belt 411 is always located within the groove of the driving pulley 41 and the driven pulley 42. The first transmission belt 411 and the second transmission belt 521 are selected as trapezoidal V-belts. The first transmission belt 411 and the second transmission belt 521 have sufficient overlap in the groove depth direction of the pulleys. When the tension of the first transmission belt 411 is within a suitable range, it can ensure the reliability of the driving power roller 32 without hindering the overall vibration amplitude and frequency of the side plate 10, the screen 20 and the belt 30.

[0025] It should be noted that when the power pulley 52 and the follower pulley 53 are in a position far apart or close together, the second transmission belt 521 is always located within the groove of the power pulley 52 and the follower pulley 53. The tension fluctuation range of the second transmission belt 521 is set with reference to the tension fluctuation range of the first transmission belt 411. Setting the tension of the second transmission belt 521 to a certain fluctuation range ensures that the transmission belt needs to maintain a cooperative relationship with the pulley to transmit torque, while not hindering the overall vibration of the side plate 10, screen 20, and belt 30.

[0026] like Figure 7 , 8 As shown, the feeding rods 31A or plates 31B are arranged alternately on the belt 30.

[0027] During the vibration process, the 31A or plate 31B on the belt 30 has the function of moving the grass embryo downstream, and at the same time, it works in conjunction with the up-and-down vibration of the screen 20 to apply a beating effect to the grass. Under the combined action of up-and-down vibration, turning and beating, the dust and ash on the grass embryo and between the grass gaps are effectively removed.
