Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a pulsating rubbing type banana stalk fiber extractor. Background Technique

[0002] Banana stalks are the main by-products after banana harvesting. After the bananas are picked, a lot of banana stalk waste is generated. For a long time, due to the lack of effective recycling methods, these banana stalks are cut and discarded in the field after being left in the field for a period of time, and then they are naturally decomposed or burned when they are dry. This not only causes waste of resources, but also is more likely to cause plant disease hazards. The fibers in banana stalks can be used for papermaking, and various vitamins in banana stalks have high nutritional value and can be used to process feed. The methods for extracting banana stalk fibers mainly include water immersion method, biochemical method and mechanical extraction method. Among them, the mechanical extraction method has high efficiency, low impurity content, less pollution, and good fiber gloss and softness.

[0003] In the prior art, the mechanical extraction method mainly relies on scraping impurities. When the banana stalk fiber extractor operates, there are defects such as high impurity content, serious fracture and machine winding blockage. Therefore, it is necessary to provide a pulsating rubbing type banana stalk fiber extractor.

[0004] After retrieval, the Chinese invention patent with the publication number of CN111663188B discloses a scraping belt multi-tooth type banana stalk fiber extractor, which includes a frame, a feeding device, a fiber scraping device and a discharging device; the feeding device, the fiber scraping device and the discharging device are sequentially installed on the frame from top to bottom. This application drives the scraping teeth to move through the operation of the scraping belt, so as to achieve the effect of scraping banana stalk fibers. However, during the process of scraping the stalks by the scraping teeth, it is inevitable to entangle with the fibers, which will cause the scraping teeth to be easily blocked, thereby affecting the operation of the equipment and the fiber extraction effect. Summary of the Utility Model

[0005] Aiming at the above-mentioned prior art, the utility model aims to provide a pulsating rubbing type banana stalk fiber extractor, and the main technical problem to be solved is how to improve the banana stalk fiber extraction effect.

[0028] Embodiment

[0029] Referring to the attached Figures 1-4 , this application provides a pulsating rubbing type banana stalk fiber extractor, which includes a protective hood 1 and a frame 2. A power device 3, a rubbing device 4 and an extrusion device 5 are arranged on the frame 2. The rubbing device 4 and the extrusion device 5 rub and extrude the stalks respectively through the power device 3;

[0030] The rubbing device includes an upper rubbing belt 42 and a lower rubbing belt 43. The upper rubbing belt 42 and the lower rubbing belt 43 are arranged in parallel, and the running directions of the upper rubbing belt 42 and the lower rubbing belt 43 are opposite. By using the relative movement directions of the upper rubbing belt 42 and the lower rubbing belt 43, the banana stalks can be gently rubbed to extract fibers. The rubbing method is relatively gentle, which can maximize the quality of the obtained fibers. The rotational scraping is changed to translational rubbing, fundamentally solving the defect of fiber winding and blocking the machine. The extrusion device 5 includes a cam 53, a driven roller 54, an extrusion roller 57 and a roller bracket 58. The extrusion roller 57 is arranged inside the roller bracket 58, and the extrusion roller 57 is located inside the upper rubbing belt 42. The driven roller 54 is arranged outside the roller bracket 58. The cam 53 makes the extrusion roller 57 reciprocate by periodically hitting the driven roller 54.

[0031] Preferably, two driving rollers 44 and two driven rollers 45 are respectively rotatably connected to both sides of the top end of the frame 2. The upper rubbing belt 42 and the lower rubbing belt 43 are respectively sleeved outside the driving roller 44 and the driven roller 45 at the same height. The running speed of the upper rubbing belt 42 is greater than that of the lower rubbing belt 43. The leading end of the lower rubbing belt 43 protrudes from the upper rubbing belt 42, and the trailing ends of the lower rubbing belt 43 and the upper rubbing belt 42 are flush. The longer lower rubbing belt 43 can facilitate the placement of the stem slices into the two rubbing belts.

[0032] Preferably, the power device 3 includes a motor. A first pulley is key-connected to the outside of the output shaft of the motor and one end of the driving roller 44 located inside the lower rubbing belt 43. The same first belt is sleeved outside the two first pulleys. One side of the top end of the frame 2 is rotatably connected with a connecting shaft. A gear 41 is key-connected to the other end of the driving roller 44 located inside the lower rubbing belt 43 and the rod body of the connecting shaft. The two gears 41 are meshed. A second pulley is key-connected to one end of the driving roller 44 located inside the upper rubbing belt 42 and one end of the connecting shaft. The same second belt is sleeved outside the two second pulleys.

[0033] Preferably, a cross beam is provided above the upper rubbing belt 42 at the top end of the frame 2. Springs 59 are fixedly connected to both sides of the bottom end of the cross beam. The roller bracket 58 is fixedly connected to the bottom end of the spring 59, so that the roller bracket 58 is always subjected to a downward spring pressure to ensure that the cam follower roller 54 is in contact with the cam 53. A plurality of sliders 56 are fixedly connected to the outside of the roller bracket 58. A plurality of guide rails 55 are fixedly connected to the outside of the upper rubbing belt 42 of the frame 2. The number of the sliders 56 is the same as that of the guide rails 55 and they are in one-to-one correspondence. The sliders 56 are slidably connected to the outside of the guide rails 55. The cam 53 rotates synchronously with the power device 3, so that the extrusion roller 57 moves up and down reciprocally, thereby pushing and squeezing the upper rubbing belt 42 to periodically squeeze the banana stem. Therefore, under the periodic up and down movement of the pulsating extrusion mechanism 5, the lower surface of the upper rubbing belt 42 repeatedly squeezes the banana stem to realize dehydration, break the original plant structure, facilitate fiber extraction. At the same time, under the rubbing action of the rubbing belt, impurities such as colloid in the banana stem are rubbed and removed, and the fiber bundle is conveyed out following the lower rubbing belt.

[0034] Preferably, rotating shafts are respectively rotatably connected to both ends inside the upper rubbing belt 42 of the frame 2. A sprocket 52 is key-connected to one end of each of the two rotating shafts. The same chain 51 is sleeved outside the two sprockets 52. The cam 53 is key-connected to the outside of the rotating shaft, and the cam 53 corresponds to the follower roller 54 up and down. A third pulley is key-connected to one end of the output shaft of the motor and one end of the rotating shaft close to the motor side. The same third belt is sleeved outside the two third pulleys.

[0035] Preferably, universal casters 6 with brakes are fixedly connected to the outer sides of the four corners at the bottom of the frame 1, facilitating the device to move its position at any time and be fixed on the ground after movement.

[0036] Working principle: When using this device, the rubbing device 4 and the extrusion device 5 can be driven by the power device 3. That is, after starting the motor, the motor can drive the lower rubbing belt 43 and the upper rubbing belt 42 to run respectively through the first belt, the second belt and the third belt, and the cam 53 to rotate. When the cam 53 rotates, it will periodically impact the driven roller 54, so that the roller bracket 58 continuously moves up and down reciprocally under the elastic force of the spring 59. Therefore, the roller bracket 58 can drive the extrusion roller 57 to continuously move up and down reciprocally inside the upper rubbing belt 42. Therefore, after placing the stem slices between the upper rubbing belt 42 and the lower rubbing belt 43, the extrusion roller 57 can intermittently push the lower surface of the upper rubbing belt 42, making it repeatedly extrude the banana stems to achieve dehydration. At the same time, with the running mode of the upper rubbing belt 42 and the lower rubbing belt 43 with different speeds and opposite directions, it is possible to align and extrude while rubbing the stems, thereby breaking the original plant structure and making the fiber extraction process more convenient.

[0037] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
