Description

Technical Field

[0001] This utility model relates to the field of plant processing equipment technology, specifically to a Eucommia ulmoides leaf-stem separation device. Background Technology

[0002] Eucommia ulmoides is a precious plant with high economic and medicinal value. In recent years, with in-depth research on Eucommia ulmoides, researchers have discovered that Eucommia ulmoides leaves have similar chemical compositions to Eucommia ulmoides bark, and the content of certain polyphenolic compounds in Eucommia ulmoides leaves is higher than that in Eucommia ulmoides bark. Therefore, how to efficiently process Eucommia ulmoides leaves and extract its effective components has become one of the research hotspots in this field. The Eucommia ulmoides leaf-stem separation device is a specially designed device for separating Eucommia ulmoides leaves and stems. This device has advantages such as high automation, high separation efficiency, and reduced loss of effective components, and has broad application prospects in the processing of Eucommia ulmoides leaves. However, the existing technology has the following problems:

[0003] Existing Eucommia ulmoides leaf-stem separation devices lack clamping components, making it impossible to effectively hold branches of varying thicknesses. Manual operation requires constant hand or tool manipulation to secure the branches and leaves in the correct separation position, increasing labor intensity and complicating the entire process. Furthermore, manual securing poses safety risks. The devices lack vibration separation components, relying solely on the rotation of the separation rollers. For tightly connected branches and stems, the separation effect is significantly reduced, resulting in some leaves failing to detach completely. Without vibration assistance, the separation rollers can only separate leaves from the surface or specific areas of the branch, slowing down the process and requiring more time to process the same number of branches, thus reducing the device's processing efficiency.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1 , Figure 2 As shown, this utility model provides a Eucommia ulmoides leaf and stem separation device, including a base 10, a fixed frame 11 fixedly connected to the top of the base 10, a central controller 12 fixedly connected to the left side wall of the fixed frame 11, inclined plates 13 fixedly connected to the inner walls of the left and right sides of the fixed frame 11, a leaf collection tray 14 slidably connected to the bottom of the inclined plate 13 and the inner bottom wall of the fixed frame 11, a handle 15 fixedly connected to the front side wall of the leaf collection tray 14, side plates 16 fixedly connected to the top four corners of the fixed frame 11, a leaf and stem vibration separation component 3 is provided in the middle of the opposite surface of the left and right side plates 16, and a clamping component 2 is provided on the top of the leaf and stem vibration separation component 3.

[0023] The central controller 12 serves as the control core of the entire device and is responsible for coordinating the work of various components. A handle 15 is fixedly connected to the front side wall of the blade collection tray 14 to facilitate the removal of the blade collection tray 14 to collect the separated blades.

[0024] like Figure 3 As shown, the clamping assembly 2 includes a double-ended screw 20, which is rotatably connected to the upper surface of the two right side plates 16. A motor 22 is fixedly connected to the front wall of the right front side plate 16. The output end of the motor 22 extends through to the rear wall of the right front side plate 16 and is fixedly connected to the double-ended screw 20. A slide rod 21 is fixedly connected to the upper surface of the two left side plates 16. The outer walls of the double-ended screw 20 are threaded with clamping moving plates 23 that are slidably connected to the outer walls of the slide rod 21 on both the front and rear sides. Silicone fixing plates 24 are fixedly connected to the upper and lower surfaces of the two clamping moving plates 23. The central controller 12 is electrically connected to the motor 22.

[0025] First, the Eucommia ulmoides branches and leaves to be separated are placed in the clamping assembly 2. When the central controller 12 starts the motor 22, the double-headed screw 20 rotates. Since it is threadedly connected to the clamping moving plates 23 on the front and rear sides, and the clamping moving plates 23 are also slidably connected to the slide rod 21, under the action of threaded transmission and slide rod guidance, the two clamping moving plates 23 move relative to each other or away from each other. The silicone fixing plate 24 on their opposite sides can clamp or release the Eucommia ulmoides branches and leaves. The silicone material can avoid damaging the branches and leaves. Through the clamping assembly 2, the distance between the two clamping moving plates 23 can be effectively adjusted to effectively clamp branches of different thicknesses. There is no need for manual handling of the Eucommia ulmoides branches and leaves to place them in a suitable separation position, which reduces the labor intensity of the operator and ensures the safety of the operator. At the same time, the clamping moving plates 23 can firmly fix the Eucommia ulmoides branches, so that they remain in a stable position under strong mechanical force, thereby ensuring the accuracy and efficiency of leaf and stem separation.

[0026] like Figure 4-6 As shown, the leaf stem vibration separation assembly 3 includes a second motor 30, which is fixedly connected to the right side wall of the right front side plate 16. A rotating rod 31 is rotatably connected to the opposite surfaces of the two front side plates 16. The output end of the second motor 30 passes through to the left side wall of the right front side plate 16 and is fixedly connected to the rotating rod 31. Two sliding rods 32 are fixedly connected to the opposite surfaces of the front and rear side plates 16. A moving frame 33 is slidably connected to the outer wall of the two sliding rods 32. A crank 34 is fixedly connected to the middle of the outer wall of the rotating rod 31. Two symmetrically fixed plates 35 are fixedly connected to the front side of the moving frame 33. Rollers 36 that fit against the outer wall of the crank 34 are rotatably connected to the opposite front surfaces of the two left and right fixed plates 35. Fixed plates 37 are fixedly connected to the rear sides of the opposite surfaces of the two front side plates 16. Springs 38 are fixedly connected to the rear side walls of the two left and right fixed plates 37. The rear ends of the two left and right springs 38 are fixedly connected to the front side walls of the moving frame 33. The central controller 12 is electrically connected to the second motor 30.

[0027] like Figure 4-6As shown, the left end of the rotating rod 31 extends through the left side wall of the left front side plate 16 and is fixedly connected to a bevel gear 390. The front of the bevel gear 390 is meshed with a bevel gear 392. The inner wall of the bevel gear 392 is fixedly connected to a rotating rod 391. The front end of the rotating rod 391 is rotatably connected to a fixing block 39, which is fixedly connected to the left side wall of the left front side plate 16. A limit block is fixedly connected to the end of the rotating rod 391 away from the fixing block 39. The left side wall of the moving frame 33... A fixing block 2 393 is fixedly connected to the front side. A rotating ring 394 is rotatably connected to the inner wall of the fixing block 2 393. A bevel gear 395 is fixedly connected to the rear side wall of the rotating ring 394. Spline grooves 396 are opened inside the rotating ring 394 and the bevel gear 395. The interior of the rotating ring 394 and the bevel gear 395 is movably connected to the protrusion on the outer wall of the rotating rod 2 391 through the spline grooves 396. A bevel gear 4 397 is meshed with the right side of the bevel gear 395.

[0028] like Figure 4-6 As shown, two symmetrically arranged separating rollers 398 are rotatably connected to the inner walls of the left and right sides of the movable frame 33. Several equally spaced and staggered leaf-beating cutters are fixedly connected to the outer walls of the front and rear separating rollers 398. The left end of the front separating roller 398 extends through to the left outer wall of the movable frame 33 and is fixedly connected to the bevel gear 397. The right ends of the front and rear separating rollers 398 extend through to the right outer wall of the movable frame 33 and are fixedly connected to the gear 399. The front and rear gears 399 are meshed together.

[0029] Next, the leaf stem vibration separation assembly 3 starts to work. Motor 2 30 is fixed to the right side wall of the right front side plate 16. Its output end is connected to the rotating rod 31 rotatably connected between the two front side plates 16. Motor 2 30 is started by the central controller 12. After motor 2 30 is started, the rotating rod 31 rotates, and the crank 34 in the middle of its outer wall rotates accordingly. The roller 36 on the fixed plate 35 on the front side wall of the moving frame 33 is in contact with the outer wall of the crank 34, and the moving frame 33 is slidably connected to the sliding rod 2 32 between the front and rear side plates 16. At the same time, under the elastic force of the spring 38, the moving frame 33 reciprocates on the sliding rod 2 32.

[0030] While the moving frame 33 vibrates, the bevel gear 390 at the left end of the rotating rod 31 drives the bevel gear 392 meshing with it to rotate. The bevel gear 392 drives the rotating rod 391 to rotate. The rotating rod 391 is connected to the rotating ring 394 and the bevel gear 395 through the spline groove 396, causing the bevel gear 395 to rotate. While rotating, the rotating ring 394 and the bevel gear 395 can also slide on the outer wall of the rotating rod 391. The bevel gear 395 then drives the bevel gear 397 meshing with it to rotate. The bevel gear 397 is fixedly connected to the front separating roller 398. The front separating roller 398 rotates, and the two separating rollers 398 are connected by the gear 399 at the right end to achieve synchronous reverse rotation. Several staggered... During rotation, the leaf-breaking cutter repeatedly strikes, kneads, and pulls the Eucommia ulmoides branches fixed by the clamping component 2, causing the leaves to gradually separate from the stems under vibration and mechanical action. The separated leaves slide down the inclined plate 13 into the leaf collection tray 14 under gravity, thus completing the separation of Eucommia ulmoides leaves and stems. Through the leaf and stem vibration separation component 3, the reciprocating vibration of the separation roller 398 can repeatedly stretch and shake the leaf and stem connection of the Eucommia ulmoides branches, making the leaf and stem connection easier to loosen and the leaves easier to fall off the stems, thereby greatly improving the separation effect. At the same time, the branches will continuously change position and posture during vibration, allowing leaves from all parts to be processed by the separation roller 398, thereby accelerating the overall separation speed and improving work efficiency.

[0031] It should be noted that the central controller 12 is existing technology and will not be discussed in detail here.

[0032] The working principle of this Eucommia ulmoides leaf-stem separation device will be explained in detail below.

[0033] like Figure 1-6 As shown, firstly, the Eucommia ulmoides branches and leaves to be separated are placed in the clamping assembly 2. When the central controller 12 starts the motor 22, the double-headed screw 20 rotates. Since it is threadedly connected to the clamping moving plates 23 on the front and rear sides, and the clamping moving plates 23 are also slidably connected to the slide rod 21, under the action of threaded transmission and slide rod guidance, the two clamping moving plates 23 move relative to each other or away from each other. The silicone fixing plate 24 on their opposite sides can clamp or release the Eucommia ulmoides branches and leaves. The silicone material can avoid damaging the branches and leaves. Through the clamping assembly 2, the distance between the two clamping moving plates 23 can be effectively adjusted to effectively clamp branches of different thicknesses. There is no need for manual handling of the Eucommia ulmoides branches and leaves to place them in a suitable separation position, which reduces the labor intensity of the operator and ensures the safety of the operator. At the same time, the clamping moving plates 23 can firmly fix the Eucommia ulmoides branches, so that they remain in a stable position under strong mechanical force, thereby ensuring the accuracy and efficiency of leaf and stem separation.

[0034] Next, the leaf stem vibration separation assembly 3 starts to work. Motor 2 30 is fixed to the right side wall of the right front side plate 16. Its output end is connected to the rotating rod 31 rotatably connected between the two front side plates 16. Motor 2 30 is started by the central controller 12. After motor 2 30 is started, the rotating rod 31 rotates, and the crank 34 in the middle of its outer wall rotates accordingly. The roller 36 on the fixed plate 35 on the front side wall of the moving frame 33 is in contact with the outer wall of the crank 34, and the moving frame 33 is slidably connected to the sliding rod 2 32 between the front and rear side plates 16. At the same time, under the elastic force of the spring 38, the moving frame 33 reciprocates on the sliding rod 2 32.

[0035] While the moving frame 33 vibrates, the bevel gear 390 at the left end of the rotating rod 31 drives the bevel gear 392 meshing with it to rotate. The bevel gear 392 drives the rotating rod 391 to rotate. The rotating rod 391 is connected to the rotating ring 394 and the bevel gear 395 through the spline groove 396, causing the bevel gear 395 to rotate. While rotating, the rotating ring 394 and the bevel gear 395 can also slide on the outer wall of the rotating rod 391. The bevel gear 395 then drives the bevel gear 397 meshing with it to rotate. The bevel gear 397 is fixedly connected to the front separating roller 398. The front separating roller 398 rotates, and the two separating rollers 398 are connected by the gear 399 at the right end to achieve synchronous reverse rotation. Several staggered... During rotation, the leaf-breaking cutter repeatedly strikes, kneads, and pulls the Eucommia ulmoides branches fixed by the clamping component 2, causing the leaves to gradually separate from the stems under vibration and mechanical action. The separated leaves slide down the inclined plate 13 into the leaf collection tray 14 under gravity, thus completing the separation of Eucommia ulmoides leaves and stems. Through the leaf and stem vibration separation component 3, the reciprocating vibration of the separation roller 398 can repeatedly stretch and shake the leaf and stem connection of the Eucommia ulmoides branches, making the leaf and stem connection easier to loosen and the leaves easier to fall off the stems, thereby greatly improving the separation effect. At the same time, the branches will continuously change position and posture during vibration, allowing leaves from all parts to be processed by the separation roller 398, thereby accelerating the overall separation speed and improving work efficiency.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
