Description

Technical Field

[0001] This utility model relates to the field of ramie processing technology, specifically to a fixed-length cutting device for ramie processing. Background Technology

[0002] Ramie, a natural fiber crop with a long history, holds an important position in the textile industry due to its unique air permeability, moisture absorption, and antibacterial properties. The extraction process of ramie fiber involves steps such as harvesting and pretreatment, soaking, peeling, fermentation, and washing. With the development of modern technology and the improvement of people's living standards, the market demand for ramie products is increasing, and higher requirements are being placed on the processing quality of ramie fiber. In traditional ramie processing, the peeling process mostly relies on manual operation. Simple mechanical peeling mostly involves cracking the soaked ramie stalks, after which the husks on the stalks can be easily separated from the core. However, manual peeling and simple mechanical peeling are not only inefficient, but also make it difficult to ensure that each ramie stalk is cracked during the cracking process, and it is also difficult to guarantee the consistency of ramie fiber length and processing efficiency, thus affecting the quality of the final product. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model proposes the following technical solution:

[0004] A fixed-length cutting device for ramie processing includes a base and a height scale. An adjusting screw is rotatably mounted on the base, and a lifting block is slidably mounted on the base. The lifting block and the adjusting screw are connected by a thread. A scale frame is also fixedly mounted on the base, and the scale frame is provided with height scales to determine the distance between the lifting block and the base. The distance between the lifting blocks can be adjusted by rotating the adjusting screw. A plurality of protruding arc plates are provided at one end of the lifting block near the base. The protruding arc plates are arranged in a stepped manner on the lifting block to further compress the ramie stalks.

[0005] Furthermore, a feeding cylinder is rotatably mounted on one side of the lifting block, and multiple extrusion protrusions are provided on the feeding cylinder for anti-slip purposes. An extrusion cylinder is rotatably mounted on the other side of the lifting block, and multiple rubber pressure blocks are provided on the outer wall of the extrusion cylinder for extruding ramie stalks.

[0006] Furthermore, a feed baffle is fixedly installed on one side of the lifting block, a rotating plate is rotatably installed on the feed baffle, and a sliding block is slidably installed on the rotating plate.

[0007] Furthermore, an angle screw is rotatably mounted on the sliding block. The angle screw is threadedly connected to the feed baffle. Rotating the angle screw can drive the rotating plate to rotate on the feed baffle, thereby adjusting the amount of ramie stalks fed.

[0008] Furthermore, a secondary pressure rod is fixedly installed on one side of the lifting block, and the extrusion cylinder is disposed between the secondary pressure rod and the lifting block. The secondary pressure rod is used to extrude ramie stalks.

[0009] Furthermore, a cutting frame is fixedly installed on the base, a turntable is rotatably installed on the cutting frame, a rocker arm is rotatably installed on the turntable, the rocker arm is eccentrically positioned on the turntable, and a cutting blade is rotatably installed at the other end of the rocker arm, the cutting blade being slidably connected to the cutting frame.

[0010] The beneficial effects of this invention compared with the prior art are: (1) This device breaks ramie stalks by multiple protruding arc plates on the lifting block, which can not only speed up the subsequent processing efficiency, but also improve the cutting accuracy; (2) When this device is working, the number of ramie stalks cut at one time can be controlled by adjusting the distance between the lifting block and the base. At the same time, the amount of material fed at one time can also be adjusted by adjusting the angle of the rotating plate on the feed baffle. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0017] like Figure 1 and Figure 4As shown, a fixed-length cutting device for ramie processing includes a base 101 and a transfer frame 102 for transferring ramie rods. A cutting frame 104 is fixedly installed on the base 101, and a cutting motor is fixedly installed on the cutting frame 104. A turntable 103 is fixedly installed on the output shaft of the cutting motor. The turntable 103 is rotatably connected to the cutting frame 104. A rocker arm 105 is rotatably installed on the turntable 103. The rocker arm 105 is eccentrically positioned on the turntable 103. A cutting blade 106 is rotatably installed at the other end of the rocker arm 105. The cutting blade 106 is slidably connected to the cutting frame 104. The cutting frame 104 is used to limit the sliding direction of the cutting blade 106.

[0018] like Figures 1 to 3 As shown, an adjusting screw 201 is rotatably mounted on the base 101, and a lifting block 202 is slidably mounted on the base 101. The lifting block 202 and the adjusting screw 201 are connected by threads. A scale frame 203 is also fixedly mounted on the base 101. The scale frame 203 is provided with height scales to confirm the distance between the lifting block 202 and the base 101. The distance between the lifting blocks 202 can be adjusted by rotating the adjusting screw 201. Multiple protruding arc plates are provided at one end of the lifting block 202 near the base 101. The protruding arc plates are arranged in a stepped manner on the lifting block 202 to further compress the ramie stalk.

[0019] like Figures 1 to 3 As shown, a rolling motor is fixedly installed on the lifting block 202, and a feeding cylinder 210 is fixedly installed on the output shaft of the rolling motor. Multiple extrusion protrusions are provided on the feeding cylinder 210 for anti-slip purposes. A limiting motor is fixedly installed on the lifting block 202, and an extrusion cylinder 205 is fixedly installed on the output shaft of the limiting motor. Multiple rubber pressure blocks are provided on the outer wall of the extrusion cylinder 205 for extruding ramie stalks. A feeding baffle 209 is fixedly installed on one side of the lifting block 202. The feeding cylinder 210 is positioned between the feeding baffle 209 and the lifting block 202. A rotating plate 208 is rotatably installed on the feeding baffle 209, and a sliding plate is mounted on the rotating plate 208. A sliding block 207 is provided, on which an angle screw 206 is rotatably mounted. The angle screw 206 is threadedly connected to the feed baffle 209. Rotating the angle screw 206 can drive the rotating plate 208 to rotate on the feed baffle 209, thereby adjusting the amount of ramie stalks fed. A secondary pressure rod 204 is fixedly mounted on one side of the lifting block 202. The extrusion cylinder 205 is disposed between the secondary pressure rod 204 and the lifting block 202. The secondary pressure rod 204 is used to extrude the ramie stalks. The distance between the extrusion cylinder 205 and the base 101 is smaller than the distance between the feed cylinder 210 and the base 101, so that the ramie stalks are extruded more smoothly under the extrusion cylinder 205.

[0020] Working Principle: In use, ramie stalks are placed into the device from one end of the rotating plate 208. During placement, the angle of the rotating plate 208 on the feed baffle 209 can be adjusted by rotating the angle screw 206. When the ramie stalk enters below the feed cylinder 210, the crushing motor starts, driving the feed cylinder 210 to rotate. The feed cylinder 210 then drives the ramie stalk to move towards the cutting blade 106, allowing it to be crushed step-by-step by the protruding arc plate at the bottom of the lifting block 202. This crushing process cracks the ramie stalk's surface, facilitating subsequent processing. After passing the lifting block 202, the ramie stalk contacts the extrusion cylinder 205. At this point, the limiting motor drives the extrusion cylinder 205 to rotate, allowing it to continue... The ramie stalk is driven to move below the cutting blade 106. Once the ramie stalk is below the cutting blade 106, the extrusion cylinder 205 rotates, driving a certain length of ramie stalk past the cutting blade 106. After the ramie stalk has moved a certain length outside the device, the cutting motor is started, causing the turntable 103 to rotate. The turntable 103 then drives the cutting blade 106 to slide closer to the base 101 via the rocker arm 105. This allows the cutting blade 106 to work with the base 101 to cut the ramie stalk, thus completing the fixed-length cutting process. During the cutting process, the ramie stalk is continuously squeezed until it breaks, which is to facilitate the removal of the ramie skin in subsequent processes. The cut ramie stalk then falls into the transfer frame 102.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
