Description

Technical Field

[0001] This utility model relates to the field of jute fiber technology, specifically to a jute fiber degumming device. Background Technology

[0002] The prior art and its shortcomings are discussed, for example, Chinese utility model patent with authorization announcement number CN223017048U discloses a flax fiber degumming device, which relates to the field of degumming device technology. It includes a base frame, a degumming cylinder fixedly connected to the base frame, a frame fixedly connected to the outer wall of the degumming cylinder, a controller and a first motor fixedly connected to the outer wall of the frame, a telescopic rod fixedly connected to the inner wall of the frame, and a clamp fixedly connected to one end of the telescopic rod.

[0003] A cleaning assembly is included to remove residual solvent from flax fibers. The cleaning assembly is connected to the base frame. This invention solves the problem that residual solvent in flax fibers is difficult to remove after degumming, hindering further processing of the flax fibers.

[0004] However, existing jute fiber degumming devices simply clamp the jute fibers onto a clamp and lower them into a dissolving solution to dissolve the bio-colloids in the jute fibers. During the biological degumming (jute retting) process, the water may become stagnant, which can easily lead to uneven degumming.

[0005] Therefore, we propose a jute fiber degumming device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a jute fiber degumming device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a jute fiber degumming device, comprising a degumming tank, a fixed frame fixedly connected to the top surface of the degumming tank, a hydraulic cylinder fixedly installed on the top surface of the fixed frame, a connecting rod fixedly connected to the output end of the hydraulic cylinder, a connecting plate fixedly connected to the bottom end of the connecting rod, multiple fixed rods fixedly connected to the bottom surface of the connecting plate, a movable plate fixedly connected to the bottom end of the fixed rods, multiple water-permeable holes opened on the top surface of the movable plate, a connecting liner plate connected to the movable plate by multiple bolts, and a rubber pad fixedly provided on the bottom surface of the connecting liner plate.

[0008] Preferably, multiple positioning rods are fixed to the bottom surface of the movable plate, and multiple positioning grooves are opened on the top surface of the connecting liner, with the positioning rods engaging the positioning grooves.

[0009] Preferably, the top surface of the connecting liner has multiple water-permeable holes (II), and the top surface of the rubber pad has multiple water-permeable holes (III).

[0010] Preferably, the three permeable holes are internally connected.

[0011] Preferably, a slider is fixed to one side of the connecting plate, and a groove is formed on one side of the fixing frame, with the slider slidably connected to the groove.

[0012] Preferably, multiple guide rods are vertically fixed inside the slide groove, and the number of guide rods is two. Limiting sliding holes are respectively opened at both ends of the top surface of the slider, and the limiting sliding holes are slidably connected to the guide rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through the installation of a movable plate, connecting liner, and rubber pad driven by a hydraulic cylinder, allows for periodic vertical immersion into the degumming tank. As the movable plate, connecting liner, and rubber pad descend, they press all the floating hemp bundles into the water, ensuring complete submersion. The downward and upward movement of the movable plate, connecting liner, and rubber pad creates strong vertical convection and turbulence in the tank, achieving efficient water churning and improving the uniformity of degumming. The inclusion of three permeable holes allows water to pass through smoothly, reducing resistance while effectively compressing the hemp bundles. The rubber pad effectively prevents fiber damage, and the bolts facilitate maintenance and replacement of the connecting liner and rubber pad. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1:

[0023] Please see Figure 1-5 This is the first embodiment of the present invention, which provides a technical solution: a jute fiber degumming device, comprising a degumming tank 1, a fixed frame 2 fixedly connected to the top surface of the degumming tank 1, a hydraulic cylinder 3 fixedly installed on the top surface of the fixed frame 2, a connecting rod 4 fixedly connected to the output end of the hydraulic cylinder 3, a connecting plate 5 fixedly connected to the bottom end of the connecting rod 4, multiple fixed rods 6 fixedly connected to the bottom surface of the connecting plate 5, a movable plate 7 fixedly connected to the bottom end of the fixed rods 6, multiple water-permeable holes 71 opened on the top surface of the movable plate 7, and a connecting liner 9 connected to the movable plate 7 by multiple bolts 8. The bolts 8 are made of corrosion-resistant materials, such as stainless steel or with an anti-corrosion coating. A rubber pad 10 is fixedly provided on the bottom surface of the connecting liner 9. The rubber pad 10 is made of a corrosion-resistant and biodegradable elastic material, such as EPDM rubber, to resist corrosion from the tank water and microbial aging. To ensure the long service life of the device, the movable plate 7 is preferably made of 316 stainless steel, and the detachable connecting liner 9 can be made of 304 stainless steel or polypropylene plate.

[0024] Example 2:

[0025] Please see Figure 1-5 This is the second embodiment of the present invention. Based on the previous embodiment, multiple positioning rods 72 are fixed to the bottom surface of the movable plate 7, and multiple positioning grooves 92 are opened on the top surface of the connecting liner 9. The positioning rods 72 are engaged with the positioning grooves 92, which can be used for positioning and limiting when installing the connecting liner 9, making installation convenient.

[0026] Multiple water-permeable holes 91 are opened on the top surface of the connecting liner plate 9, and multiple water-permeable holes 101 are opened on the top surface of the rubber pad 10.

[0027] Water-permeable hole 1 (71), water-permeable hole 2 (91), and water-permeable hole 3 (101) are internally connected.

[0028] A slider 51 is fixedly connected to one side of the connecting plate 5, and a groove 21 is opened on one side of the fixed frame 2. The slider 51 slides and connects to the groove 21, which can limit the movement range of the connecting plate 5, the moving plate 7, etc., and improve the stability of the lifting of the moving plate 7, the connecting liner 9, and the rubber pad 10.

[0029] Multiple guide rods 11 are vertically fixed inside the slide groove 21. There are two guide rods 11. Limiting sliding holes 511 are opened at both ends of the top surface of the slider 51. The limiting sliding holes 511 are slidably connected to the guide rods 11, which further improves the stability of the lifting of the moving plate 7, the connecting liner 9, and the rubber pad 10.

[0030] Please see Figure 1-5In use, this invention involves filling the degumming tank 1 with natural water, such as river or pond water. The harvested jute stalks are bundled and immersed in the degumming tank 1, where natural microorganisms degumme the jute. When the jute bundles are immersed in water, they float on the surface due to the air contained within the fibers. The device is equipped with a controller (not shown in the figure), which is electrically connected to the hydraulic control system of the hydraulic cylinder 3. The controller periodically sends control signals to the hydraulic control system at preset time intervals, driving the hydraulic cylinder 3 to move the moving plate 7, connecting liner 9, and rubber pad 10 in a complete working cycle of downward movement, pressure holding, upward movement, and stagnation. When the moving plate 7… When the connecting liner 9 and rubber pad 10 are lowered, all the hemp bundles floating on the water surface can be pressed into the water, ensuring that all the hemp bundles are completely submerged in the water. The process of moving plate 7, connecting liner 9, and rubber pad 10 moving down and up creates strong vertical convection and turbulence in the pool water, achieving efficient water churning and improving the uniformity of degumming. By setting water permeable holes 1 71, 2 91, and 3 101, water can be allowed to pass through smoothly, reducing movement resistance and effectively suppressing the hemp bundles. By setting rubber pad 10, the fibers can be effectively cut. By setting bolt 8, the maintenance and replacement of connecting liner 9 and rubber pad 10 can be facilitated.
