Description

Technical Field

[0001] This utility model relates to the field of hemp fiber processing technology, and in particular to a drying device for hemp fiber processing. Background Technology

[0002] As an important natural fiber material, hemp fiber has been widely used in textiles, papermaking, composite materials and other fields due to its advantages such as strong moisture absorption, good air permeability and high strength. In the process of hemp fiber processing, drying is a key process, and its effect directly affects the quality of hemp fiber and the performance of subsequent products.

[0003] Currently, there are various types of hemp fiber drying devices on the market, among which the most common types are hot air circulation drying devices and infrared drying devices. Hot air circulation drying devices use a fan to continuously circulate hot air in the drying chamber, and utilize the heat exchange between the hot air and the hemp fibers to remove the moisture and achieve the drying purpose. Infrared drying devices, on the other hand, utilize the thermal effect of infrared rays to directly radiate the hemp fibers, promoting the evaporation of moisture.

[0004] However, existing drying devices generally have some problems. On the one hand, the drying efficiency is low. Due to the special structure of hemp fiber, the moisture is unevenly distributed within it. Existing drying methods cannot evaporate the moisture quickly and evenly, resulting in long drying times and failing to meet the high-efficiency requirements of large-scale industrial production. Therefore, a drying device for hemp fiber processing is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drying device for hemp fiber processing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drying device for processing hemp fibers includes a box body. A fixing block is fixedly installed on the bottom inner wall of the box body. The fixing block is U-shaped. A guide groove is opened on the top side of the fixing block. A guide block is slidably installed in the guide groove. A rotary motor is fixedly installed on one side of the guide block. The output end of the rotary motor rotates through the guide block and is fixedly installed with a rotating rod. A fixing cylinder is fixedly sleeved on the outside of the rotating rod. A long groove is opened on one side inner wall of the fixing block. A height adjustment component is arranged in the long groove. An auxiliary extrusion component and a drying component are respectively arranged in the fixing block and the box body.

[0008] Preferably, the height adjustment assembly includes a threaded motor fixedly installed on the top side of a fixed block, the output end of the threaded motor rotatably passing through the fixed block and fixedly installed with a threaded rod, a slider threadedly sleeved on the outer side of the threaded rod, the slider being adapted to the long groove, and the other end of the rotating rod being rotatably connected to one side of the slider.

[0009] Preferably, the auxiliary extrusion assembly includes a fixed rod fixedly installed inside a fixed block, and a movable cylinder movably sleeved on the outside of the fixed rod, with the movable cylinder located below the fixed cylinder.

[0010] Preferably, the drying assembly includes a mounting frame fixedly installed on one inner wall of the box body, multiple heating rods arranged inside the mounting frame, and multiple drive motors fixedly installed on the top side of the box body. The output ends of the multiple drive motors rotate through the box body and are fixedly connected to multiple fan blades.

[0011] Preferably, through holes are fixedly opened on both sides of the box body, a first fixing frame is fixedly installed on one side of the box body, a first conveyor belt is arranged inside the first fixing frame, the first conveyor belt is located at the right through hole, a second fixing frame is fixedly installed on the inner wall of one side of the box body, a second conveyor belt is arranged inside the second fixing frame, the second conveyor belt is located at the left through hole.

[0012] Preferably, a collection box is placed on the bottom inner wall of the fixed block, and the collection box is located below the movable cylinder.

[0013] Preferably, a door is provided on one side of the box body, and the door has an observation window.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The fixed cylinder and the movable cylinder work together to squeeze the hemp fiber. The fixed cylinder is driven by a rotating rod driven by a rotary motor, and the movable cylinder is installed in a fixed block through a fixed rod. The two work together to squeeze out a large amount of water from the hemp fiber, reducing the amount of water that needs to be evaporated for subsequent drying. Then, multiple heating rods in the drying component are installed in the mounting frame for preheating. Fan blades driven by multiple drive motors quickly blow heat onto the hemp fiber conveyed by the second conveyor belt. This process of squeezing and dehydrating before drying greatly shortens the drying time and effectively solves the problem of low drying efficiency caused by uneven moisture distribution in traditional drying methods, meeting the needs of large-scale industrial production.

[0016] 2. The threaded motor is fixed on the top side of the fixed block. Its output shaft drives the threaded rod to rotate. The slider, which is threadedly connected to the threaded rod, moves in the long groove. Because the slider is rotatably connected to the rotating rod, and the rotating rod is fixed to the guide block, the guide block slides in the guide groove of the fixed block. Therefore, the distance between the fixed cylinder and the movable cylinder can be precisely adjusted. Whether it is a thick bundle of hemp fiber or a thin hemp fiber fabric, it can be effectively squeezed through this adjustment mechanism to ensure the smooth progress of the subsequent drying process. This overcomes the defect of traditional devices that are difficult to adapt to various hemp fibers. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4A drying device for processing hemp fibers includes a box body 1. A fixing block 5 is fixedly installed on the bottom inner wall of the box body 1. The fixing block 5 is U-shaped. A guide groove is opened on the top side of the fixing block 5. A guide block 12 is slidably installed in the guide groove. A rotary motor 13 is fixedly installed on one side of the guide block 12. The output end of the rotary motor 13 rotates through the guide block 12 and is fixedly installed with a rotating rod 14. A fixing sleeve 15 is fixedly sleeved on the outer side of the rotating rod 14. A long groove is opened on one side inner wall of the fixing block 5. A height adjustment component is arranged in the long groove. The fixing block 5 and the box body are connected together. The unit 1 is equipped with an auxiliary extrusion assembly and a drying assembly. The height adjustment assembly includes a threaded motor 9 fixedly mounted on the top side of a fixed block 5. The output end of the threaded motor 9 rotates through the fixed block 5 and is fixedly mounted with a threaded rod 10. A slider 11 is threadedly sleeved on the outer side of the threaded rod 10. The slider 11 is adapted to the long groove. The other end of the rotating rod 14 is rotatably connected to one side of the slider 11. By providing the threaded motor 9, when it is necessary to adjust the distance between the fixed cylinder 15 and the movable cylinder 8, the threaded motor 9 is started to operate. The output shaft of the threaded motor 9 and the threaded rod 10 are connected to the threaded rod 10. The screw rod 10 and slider 11 are tightly connected. The torque generated by the motor is transmitted to the screw rod 10, causing it to rotate counterclockwise. The screw rod 10 and slider 11 are connected by a thread. When the screw rod 10 rotates counterclockwise, according to the principle of thread transmission, the slider 11 will be displaced along the axial direction of the screw rod 10. Since the slider 11 is rotatably connected to the rotating rod 14, the movement of the slider 11 will cause the rotating rod 14 to move upward synchronously. At the same time, the guide block 12 is fixed together with the rotating rod 14. The guide block 12 is embedded in the guide groove opened in the fixed block 5. When the rotating rod 14 moves upward, The guide block 12 moves accordingly. Under the constraint of the guide groove, the guide block 12 can only move along the direction of the guide groove, thereby driving the rotary motor 13 to move smoothly upward in the guide groove opened in the fixed block 5. Through the adjustment method of being driven by the threaded motor 9 and the threaded rod 10, the slider 11 and the guide block 12 working together, the distance between the fixed cylinder 15 and the movable cylinder 8 can be adjusted accurately and flexibly. Whether it is a thicker bundle of hemp fiber or a thinner hemp fiber fabric, this adjustment mechanism can achieve effective extrusion processing of hemp fibers of different shapes.

[0024] Specifically, the auxiliary extrusion assembly includes a fixed rod 7 fixedly installed inside a fixed block 5, a movable cylinder 8 movably sleeved on the outside of the fixed rod 7, the movable cylinder 8 being located below the fixed cylinder 15, and a collection box 6 placed on the bottom inner wall of the fixed block 5, located below the movable cylinder 8. With the movable cylinder 8 in place, when the fixed cylinder 15 rotates clockwise, its surface contacts the hemp fiber, and friction pushes the hemp fiber in its own rotational direction. The movable cylinder 8 and the fixed cylinder 15 cooperate to extrude the hemp fiber. During this process, the water trapped inside the hemp fiber is squeezed out. The device also includes a collection box 6, specifically designed to collect the squeezed-out water. After the water in the hemp fiber is squeezed out, it drips naturally. The collection box 6 is located directly below the path of the dripping water, effectively catching it and preventing it from scattering, maintaining a clean working environment, and facilitating subsequent unified treatment of the squeezed-out water.

[0025] Specifically, the drying assembly includes a mounting frame 18 fixedly installed on one inner wall of the box body 1, with multiple heating rods 19 installed inside the mounting frame 18, and multiple drive motors 20 fixedly installed on the top side of the box body 1. The output ends of the multiple drive motors 20 all rotate through the box body 1 and are fixedly connected to multiple fan blades 21. With the multiple heating rods 19 installed, when the hemp fiber is conveyed to the second conveyor belt 17, the multiple heating rods 19 have been preheated. At this time, it is only necessary to start the multiple drive motors 20 to drive the multiple fan blades 21 to blow heat onto the hemp fiber, thereby achieving rapid drying of the hemp fiber.

[0026] Specifically, through holes are fixedly opened on both sides of the box body 1. A first fixed frame 3 is fixedly installed on one side of the box body 1. A first conveyor belt 4 is installed inside the first fixed frame 3 and is located at the right through hole. A second fixed frame 16 is fixedly installed on the inner wall of one side of the box body 1. A second conveyor belt 17 is installed inside the second fixed frame 16 and is located at the left through hole. A box door 2 is provided on one side of the box body 1. The box door 2 has an observation window. The first conveyor belt 4 is used to transport the un-compressed and dried hemp fibers between the fixed cylinder 15 and the movable cylinder 8, while the second conveyor belt 17 is used to transport the hemp fibers that have been squeezed to remove moisture and to discharge the hemp fibers. The box door 2 is provided so that heat loss is not too fast during the drying process, which would lead to a poor drying effect of the hemp fibers. The observation window allows personnel to observe the situation inside the box body 1 at any time.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0028] In use: Start the first conveyor belt 4 and place the hemp fiber on it. As the first conveyor belt 4 continues to run, the hemp fiber will be conveyed between the fixed cylinder 15 and the movable cylinder 8. At this time, start the rotary motor 13. The motor drives the rotating rod 14 to rotate clockwise, which causes the fixed cylinder 15, which is fixedly sleeved on the outside of the rotating rod 14, to work together with the movable cylinder 8 to squeeze and convey the hemp fiber. During this process, excess water in the hemp fiber will be squeezed out, creating favorable conditions for subsequent drying. After the hemp fiber is squeezed and dehydrated by the movable cylinder 8 and the fixed cylinder 15, it will be conveyed to the second conveyor belt 17. Start the second conveyor belt 17 to start the subsequent conveying process of the hemp fiber. During the hemp fiber conveying process, multiple heating rods 19 have been pre-heated by electricity. Subsequently, multiple drives The motor 20 operates synchronously, driving multiple fan blades 21 to rotate. The heat generated by multiple heating rods 19 is blown onto the hemp fibers on the second conveyor belt 17 to dry them. Since the moisture in the hemp fibers has been squeezed out by the fixed cylinder 15 and the movable cylinder 8, the hot air blown out by the fan blades 21 can quickly dry the hemp fibers. When it is necessary to adjust the distance between the fixed cylinder 15 and the movable cylinder 8, the threaded motor 9 is started. The motor drives the threaded rod 10 to rotate counterclockwise. Under the action of the rotation of the threaded rod 10, the slider 11 drives the rotating rod 14 to move upward synchronously. The guide block 12 also drives the rotary motor 13 to move upward in the guide groove opened in the fixed block 5. Through this adjustment method, the distance between the fixed cylinder 15 and the movable cylinder 8 can be flexibly adjusted, thereby achieving effective extrusion treatment of hemp fibers of different shapes.
