Description

Technical Field

[0001] The present application relates to the field of rice paper manufacturing, and in particular to a rice paper straw embryo slag removal device. Background Art

[0002] In the process of making rice paper, the rice straw after removing the ear and the dead leaves needs to be tied into small bundles and then bundled into large bundles, and then soaked in a pool of lime water. The lime water is used to soak and soften the rice straw to increase the fiber content and thus improve the quality of the finished rice paper. After soaking for a period of time, the rice straw is fished out and air-dried. After drying, the bundles are called straw embryos. At this time, the straw embryos are mixed with a large amount of lime residue and ash residue carried by the rice straw itself. Therefore, the straw embryos contain a large amount of dust and residue, which needs to be cleaned before they can be used in the next production link. The traditional cleaning process requires manual whipping of the straw embryos to knock off the dust inside the straw embryos, and then placing the straw embryos on the screen to shake off the fallen dust. The entire manual shaking and cleaning process is time-consuming and laborious. Summary of the invention

[0003] The purpose of the present invention is to provide a rice paper straw embryo slag removal device, which can remove dust attached to the rice straw, save manpower and improve the production efficiency of rice paper.

[0004] The present invention provides the following technical solution, a straw embryo slag removal device for rice paper, characterized in that: the plate surfaces of the two side plates which are arranged parallel to each other are arranged vertically, the periphery of the screen is a square that matches the space enclosed between the two side plates, the plate edges on the side where the side plates are located on the screen are arranged at the same height in the middle of the side plates in the up and down directions, the plate edges on the screen that are perpendicular to the side plates are located at the plate edges of the side plates arranged vertically, a belt is arranged at the upper opening surrounded by the side plates, a material removing rod or plate is arranged on the belt, the belt is wound around a power roller and a reversing roller, and the belt surface of the belt is arranged parallel to the screen plate surface as a whole.

[0005] In the above technical scheme, the power roller drives the belt to move in a circular motion between the power roller and the reversing roller, the pushing rod plate on the lower belt between the power roller and the reversing roller extends downward and pushes the straw to move on the screen as the belt moves, and in the process of the straw moving from the upstream end to the downstream end on the screen, the ash attached to the straw falls from the grille holes on the screen, and the pushing of the straw by the pushing rod plate on the belt also exerts a stirring effect on the straw. The continuous change of the posture and position of the straw during the transportation of the straw from upstream to downstream improves the efficiency of ash leakage, and the straw transportation and ash cleaning tasks can be completed without the displacement of the screen plate from upstream to downstream.

[0013] The present application provides a rice paper straw embryo slag removal device, combined with Figure 1 , 2 As shown in , 3 and 4, the two side plates 10 which are arranged parallel to each other are arranged vertically, the periphery of the screen 20 is a square which matches the space enclosed between the two side plates 10, the plate edges of the screen 20 which are located on the side where the side plates 10 are located are arranged at the same height in the middle of the side plates 10 in the up and down direction, the plate edges of the screen 20 which are perpendicular to the side plates 10 are located at the plate edges of the side plates 10 which are arranged vertically, a belt 30 is arranged at the upper opening surrounded by the side plates 10, a material shifting rod or plate 31 is arranged on the belt 30, the belt 30 is wound around a power roller 32 and a reversing roller 33, and the belt surface of the belt 30 is arranged parallel to the plate surface of the screen 20 as a whole.

[0014] In the above scheme, the two side plates 10, the screen 20 and the belt 30 form a forage conveying channel, the forage is placed on the screen 20 and is moved from upstream to downstream by the material-moving rod or plate 31 arranged on the belt 30. During the displacement of the forage, the ash attached to and mixed with the forage falls through the grille holes on the screen 20. The relatively closed channel formed by the side plates 10 and the belt 30 effectively restrains the dust-raising phenomenon of the ash. In the process of moving the forage by the material-moving rod or plate 31 arranged on the belt 30, on the one hand, the posture of the forage is changed, the efficiency of cleaning is improved, and on the other hand, the forage is transported from upstream to downstream, which avoids the scheme of transporting the forage by the linear displacement of the screen 20, because if the linear displacement of the screen 20 is used to transport the forage, it is usually necessary to configure a transmission mechanism for the screen 20. In an environment with extremely severe dust, the service life of the transmission mechanism such as the chain transmission mechanism is limited, and the maintenance cost and workload cannot be controlled.

[0015] The plumb section of the structure composed of the two side plates 10 and the screen 20 is H-shaped, and the section is perpendicular to the side plate 10. With the above solution, the upper area bounded by the screen 20 constitutes a forage conveying channel, and the lower area is an ash collection area, which effectively avoids the probability of ash escaping in the process of falling.

[0016] like Figure 1 , 2 As shown, the two side plates 10 are supported on the foundation by elastic supports 40, and the side plates 10 are provided with excitation units 50. The two side plates 10 are respectively connected to the two elastic supports 40. When the excitation unit 50 vibrates the side plates 10, the side plates 10, the grille 20 and the belt 30 supported by the elastic supports 60 vibrate within a proper amplitude range in multiple degrees of freedom directions, which is beneficial to the displacement of the forage and the change of the posture of the forage, and the frequency and amplitude of the posture change are increased under the action of the material-moving rod or plate 31 arranged on the belt 30, further improving the efficiency of deashing. In addition, when the side plates 10 and the screen 20 vibrate, the vibration directions include up and down, left and right, front and back, and even rotation, which is also beneficial to the grass stems inserted or stuck in the grille holes of the screen 20 to detach from them.

[0017] like Figure 1 , 2 As shown in Figure 3, the two side plates 10 are rectangular plates and their short sides are arranged vertically. The peripheral contour of the screen 20 is rectangular. The length direction of the screen 20 is consistent with the length direction of the side plates 10. There are external flanges 11 on the upper half of the two side plates 10. 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 is to fix the belt 30 on the side plate 10, so as to ensure that the positional relationship between the belt 30 and the screen 20 is fixed, avoiding the situation where the feed rod or plate 31 cannot reach the forage due to the sudden increase in the distance between the belt 30 and the screen 20, and ensuring that the feed rod or plate 31 can exert effective pushing or digging on the forage.

[0019] like Figure 2 As shown, the two end sides of the screen 20 in the length direction are arranged at the same height or at different heights.

[0020] Preferably, due to the soft nature of the fodder and the ash attached to it and the grille holes uniformly distributed on the screen 20 with a length of 6-7 cm, it is difficult to simply rely on the feeding rod or plate 31 to move the fodder on the screen 20. The two ends of the screen 20 are arranged at an inclined angle when high and low, so that the feeding rod or plate 11 can move the fodder quickly and easily, and some of the ash retained on the screen 20 will also be shaken off the screen 20 as the screen 20 vibrates, avoiding residual ash adhering to the screen 20 during the transportation of the fodder to the downstream.

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

[0022] The first motor 40 is fixed to the ground and connected to the driving pulley 41 to drive its rotation. The power roller 32 and the first motor 40 use a belt transmission mechanism to transmit torque. Since the transmission belt has appropriate elastic properties, it can meet the needs of 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 and the driving pulley 41 and the driven pulley 42 have an appropriate coverage angle range, the power roller 32 can be reliably driven to rotate, avoiding interference with the overall vibration of the side plate 10, the screen 20 and the belt 30 structure, and at the same time avoiding 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 arranged on the foundation, a second transmission belt 521 is wound around the power pulley 52 connected to the motor shaft of the second motor 51 and the vibration pulley 53, the vibration pulley 53 and the eccentric wheel 54 are connected to the excitation wheel shaft 56, the rotating axis core of the eccentric wheel 54 is eccentrically arranged with the mass center of the eccentric wheel 54, one end of the excitation wheel shaft 56 is rotatably supported by the excitation bearing seat 55, and 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 on the ground foundation. The motor shaft output torque of the second motor 51 drives the power pulley 52 to rotate. With the help of the belt transmission mechanism composed of the power pulley 52, the second transmission belt 521 and the vibration pulley 53, the eccentric wheel 54 rotates around the axis of the exciting wheel shaft 56. Due to the distance between the mass center of the eccentric wheel 54 and the axis of the exciting wheel shaft 56, when the eccentric wheel 54 rotates, the vibration is applied to the side plate 10 through the exciting wheel shaft 56 and the exciting bearing seat 55, thereby realizing the vibration of the side plate 10, the screen 20 and the belt 30 as a whole. Preferably, as Figure 4As shown, the first transmission belt 411 and the second transmission belt 521 are V-belts with a trapezoidal cross section. When the driving pulley 41 and the driven pulley 42 are in a far away or close position, the first transmission belt 411 is always located in the belt grooves of the driving pulley 41 and the driven pulley 42. The first transmission belt 411 and the second transmission belt 521 are selected to have a trapezoidal cross section. The first transmission belt 411 and the second transmission belt 521 have sufficient overlapped parts in the belt groove depth direction of the pulleys. When the tension floating range of the first transmission belt 411 is appropriate, the reliability of the driving power roller 32 can be ensured 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 vibration pulley 53 are in a far away or close position, the second transmission belt 521 is always located in the belt groove of the power pulley 52 and the vibration pulley 53. The tension floating range of the second transmission belt 521 is set with reference to the tension floating range of the first transmission belt 411. The tension of the second transmission belt 521 is set to a certain floating range to ensure that the transmission belt needs to maintain a matching relationship with the pulley to transmit torque, while not hindering the vibration of the overall structure of the side plate 10, the screen 20 and the belt 30.

[0026] like Figure 7 , 8 As shown, the material-moving rods 31A or plates 31B are arranged on the belt 30 in an alternating manner.

[0027] During the vibration process, 31A or plate 31B on the belt 30 has the function of pulling the grass embryos to move downstream, and at the same time cooperates with the up and down vibration of the screen 20 to achieve a beating effect on the grass. Under the combined action of up and down vibration, turning and beating of the grass, dust and ash on the grass embryos and in the gaps between the grass can be effectively removed.
