Description

Technical Field

[0001] The present invention relates to the technical field of separation equipment for eucommia gum production, and particularly relates to a eucommia leaf rubbing separator for eucommia gum extraction. Background Art

[0002] Eucommia gum is a natural polymer material extracted from parts such as eucommia bark and leaves, and has good wear resistance, tear resistance, corrosion resistance and excellent insulation performance. In the process of extracting eucommia gum, the conventional separation method is to use biological enzymes to degrade the mesophyll part of eucommia leaves to obtain eucommia gum filaments in the leaf veins containing eucommia gum. However, the biochemical reaction using direct enzymatic hydrolysis method is slow and very time-consuming.

[0003] Chinese Patent CN218689966U discloses a eucommia leaf rubbing separator. By setting a pressing chamber cover to cooperate with the rubbing disk to make a circular motion, the eucommia leaves in the rubbing chamber are continuously rubbed, so as to achieve the purpose of separating the mesophyll from the leaf veins, and gradually roll into a relatively intact ellipsoidal gum filament group. However, in the process of using this scheme, the speed of eucommia gum forming into a ball is relatively slow, reducing the overall production efficiency and prolonging the extraction cycle of eucommia gum.

When in the rubbing state, the discharge ring is located above the support disk; when in the discharging state, the discharge ring is located below the support disk.

[0006] Further, a discharge pipe is fixedly connected to the lower end of the discharge ring, and the discharge pipe is communicated with the discharge port.

[0007] Further, a support cylinder is arranged on the discharge pipe. The support cylinder is sleeved on the discharge pipe, and a hydraulic telescopic cylinder is arranged between the discharge pipe and the support cylinder.

[0008] Further, it further includes a rotary bracket. The rotary bracket is installed on the base. The rotary bracket is located above the kneading disc and can revolve around the vertical central axis of the support disc, and the feed bin is installed on the rotary bracket and can rotate with the rotary bracket.

[0009] Further, the rotary bracket includes a rotary disc and three rotating arms. The rotary disc is of an annular structure. The three rotating arms are evenly distributed on the rotary disc around the first direction. Each rotating arm is connected to the support disc through a matching rotating frame. The matching rotating frame is arranged along the second direction. The second direction is the horizontal direction. One end of the matching rotating frame along the second direction is rotatably connected to the support disc, and the other end of the matching rotating frame along the second direction is rotatably connected to the rotating arm.

[0010] Further, a driving rod is arranged on the rotary bracket. The driving rod is arranged along the first direction and can rotate around its own axis. A driving arm is sleeved on the driving rod.

The first end of the kneading disk will be above the second end of the kneading disk, so that the kneading disk has a conical structure with a smaller upper end and a larger lower end. Under the promotion of its own structure, the number of Eucommia ulmoides leaves on the side close to the inner wall of the material bin will relatively increase, so that the path of the Eucommia ulmoides leaves on the side close to the inner wall of the material bin being kneaded is longer, which improves the efficiency of Eucommia ulmoides gum agglomeration to a certain extent. And the kneading disk with a spiral structure can also increase the friction force when the Eucommia ulmoides leaves contact the kneading disk, assisting in the separation of Eucommia ulmoides gum. Moreover, the discharge ring is located above the support disk, so that the conical structure of the kneading disk with a smaller upper end and a larger lower end can also prevent the Eucommia ulmoides leaves that have not been completely separated from being discharged through the discharge port on the discharge ring, resulting in waste of Eucommia ulmoides leaves.

[0016] After the Eucommia ulmoides gum is separated and agglomerated, the Eucommia ulmoides leaf kneading and separating machine for Eucommia ulmoides gum extraction is in a discharging state. The second end of the kneading disk will be above the first end of the kneading disk, so that the kneading disk has a conical structure with a larger upper end and a smaller lower end. During the process that the material bin and the lower pressing plate rotate around the vertical central axis of the support disk and drive the agglomerated Eucommia ulmoides gum to rotate, the agglomerated Eucommia ulmoides gum will not be discharged from the discharge port under the restriction of the lower pressing plate, the material bin and the kneading disk. The separated Eucommia ulmoides leaves can be discharged from top to bottom along the inclined surface of the kneading disk through the discharge ring, avoiding the separated Eucommia ulmoides leaves from adhering to the Eucommia ulmoides gum mass again.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] An embodiment of a Eucommia ulmoides leaf kneading and separating machine for Eucommia ulmoides gum extraction of the present invention is as Figures 1 to 6 shown.

[0027] A Eucommia ulmoides leaf kneading and separating machine for Eucommia ulmoides gum extraction includes a base 100, a support disk 200, a kneading disk 300, a discharging ring 400, a storage bin 600, and a lower pressing plate 700. The support disk 200 is arranged in the first direction and fixedly installed on the base 100, the first direction is the vertical direction, the kneading disk 300 is installed on the support disk 200 and is coaxial with the support disk 200. The kneading disk 300 is in a spiral structure, and the plane where its spiral line is located is a horizontal plane. One end at the center of the spiral structure of the kneading disk 300 is the first end, and one end at the outermost circle of the spiral structure of the kneading disk 300 is the second end, and the first end is coaxial with the axis of the support disk 200.

[0028] The discharging ring 400 is coaxially arranged with the supporting disc 200, and the discharging ring 400 is provided with a discharging port. The first end of the kneading disc 300 is fixedly connected to the discharging ring 400, and the second end is fixedly connected to the supporting disc 200. In the initial state, the discharging ring 400 and the supporting disc 200 are on the same horizontal plane. The silo 600 is installed on the base 100. The silo 600 is located above the kneading disc 300 and can revolve around the vertical central axis of the supporting disc 200. The lower pressing plate 700 is installed in the silo 600 so as to be able to move up and down, and can rotate with the silo 600. A kneading space for kneading Eucommia ulmoides leaves is defined among the kneading disc 300, the silo 600 and the lower pressing plate 700. The Eucommia ulmoides leaf kneading and separating machine for Eucommia ulmoides gum extraction has a kneading state and a discharging state. When in the kneading state, the discharging ring 400 is located above the supporting disc 200; when in the discharging state, the discharging ring 400 is located below the supporting disc 200.

[0029] Specifically, the silo 600 is a cylindrical bin. The diameter of the silo 600 is greater than 80 cm, and the height of the silo 600 is greater than 60 cm. Preferably, the diameter of the silo 600 is 80 cm, and the height of the silo 600 is 60 cm. The diameter of the discharging port is 30 cm. By setting the silo 600 with a large diameter, the number of kilograms of Eucommia ulmoides leaves that can be kneaded at one time is increased.

[0030] In this embodiment, by setting the cooperation of the base 100, the supporting disc 200, the kneading disc 300, the discharging ring 400, the silo 600 and the lower pressing plate 700, in the initial state, the discharging ring 400 and the supporting disc 200 are on the same horizontal plane. During use, first put the Eucommia ulmoides leaves to be kneaded into the silo 600, and then move the lower pressing plate 700 downward to limit the Eucommia ulmoides leaves in the kneading space defined by the kneading disc 300, the silo 600 and the lower pressing plate 700.

[0031] When kneading and separating the Eucommia ulmoides leaves, make the Eucommia ulmoides leaf kneading and separating machine for Eucommia ulmoides gum extraction in the kneading state, that is, make the discharging ring 400 located above the supporting disc 200. See the appendix Figure 3 As shown, since the first end of the kneading disc 300 is fixedly connected to the discharging ring 400 and the second end is fixedly connected to the supporting disc 200. Therefore, the first end of the kneading disc 300 will be located above the second end of the kneading disc 300, and further make the kneading disc 300 have a conical structure with a smaller upper end and a larger lower end. This will make the Eucommia ulmoides leaves in the silo 600 move downward along the kneading disc 300 and approach the lower part of the kneading disc 300, and to a certain extent increase the number of Eucommia ulmoides leaves on the side close to the inner wall of the silo 600. That is, under the promotion of the structure of the kneading disc 300 itself, the number of Eucommia ulmoides leaves on the side close to the inner wall of the silo 600 will relatively increase.

[0032] Then, the silo 600 is rotated around the vertical central axis of the support plate 200, and the silo 600 will drive the lower pressing plate 700 to rotate synchronously to knead the Eucommia ulmoides leaves in the silo 600. Since the number of Eucommia ulmoides leaves on the side close to the inner wall of the silo 600 relatively increases, when the silo 600 and the lower pressing plate 700 rotate to knead the Eucommia ulmoides leaves, compared with the Eucommia ulmoides leaves on the side close to the vertical central axis of the silo 600, the Eucommia ulmoides leaves on the side close to the inner wall of the silo 600 have a longer kneading path. Furthermore, when kneading the Eucommia ulmoides leaves, for each rotation of the silo 600 and the lower pressing plate 700 around the vertical central axis of the support plate 200, the degree of kneading of the Eucommia ulmoides leaves is relatively increased, which improves the efficiency of Eucommia ulmoides gum agglomeration to a certain extent. In addition, the kneading plate 300 with a spiral structure can also increase the friction force when the Eucommia ulmoides leaves come into contact with the kneading plate 300 to assist in the separation of Eucommia ulmoides gum. And the discharge ring 400 is located above the support plate 200. Furthermore, the kneading plate 300 having a conical structure with a smaller upper end and a larger lower end can also prevent the Eucommia ulmoides leaves that have not been completely separated from being discharged through the discharge port on the discharge ring 400, resulting in waste of Eucommia ulmoides leaves.

[0033] After the Eucommia ulmoides gum is separated and agglomerated, the Eucommia ulmoides leaf kneading and separating machine for Eucommia ulmoides gum extraction is in a discharging state, that is, the discharge ring 400 is located below the support plate 200. Refer to the attached Figure 5 As shown in the figure, at this time, the second end of the kneading plate 300 will be located above the first end of the kneading plate 300. Furthermore, the kneading plate 300 has a conical structure with a larger upper end and a smaller lower end. During the process that the silo 600 and the lower pressing plate 700 rotate around the vertical central axis of the support plate 200 and drive the agglomerated Eucommia ulmoides gum to rotate, the agglomerated Eucommia ulmoides gum will not be discharged from the discharge port under the restriction of the lower pressing plate 700, the silo 600 and the kneading plate 300. The separated Eucommia ulmoides leaves can be discharged from the discharge port on the discharge ring 400 along the inclined surface of the kneading plate 300 from top to bottom, avoiding the re - adhesion of the separated Eucommia ulmoides leaves to the Eucommia ulmoides gum mass and improving the working efficiency.

[0034] In this embodiment, a discharge pipe 410 is fixedly connected to the lower end of the discharge ring 400, and the discharge pipe 410 is communicated with the discharge port.

[0035] Furthermore, a support cylinder 420 is arranged on the discharge pipe 410. The support cylinder 420 is sleeved on the discharge pipe 410, and a hydraulic telescopic cylinder 430 is arranged between the discharge pipe 410 and the support cylinder 420.

[0036] In this embodiment, by providing a discharge pipe 410, the Eucommia ulmoides leaves falling from the discharge port of the discharge ring 400 can be discharged through the discharge pipe 410. And by providing a support cylinder 420 on the discharge pipe 410, during use, the support cylinder 420 is installed on the ground, and starting the hydraulic telescopic cylinder 430 can drive the discharge pipe 410 to move up and down relative to the support cylinder 420. Furthermore, the discharge ring 400 is driven to move up and down by the discharge pipe 410, enabling the Eucommia ulmoides leaf kneading and separating machine for Eucommia gum extraction to switch between the kneading state and the discharging state.

[0037] In this embodiment, an Eucommia ulmoides leaf kneading and separating machine for Eucommia gum extraction further includes a rotary support 500. The rotary support 500 is installed on the base 100, located above the kneading disc 300 and capable of revolving around the vertical central axis of the support disc 200. The material bin 600 is installed on the rotary support 500 and can rotate with the rotary support 500.

[0038] By providing the rotary support 500, during use, the rotary support 500 revolves around the vertical central axis of the support disc 200, and the rotation of the rotary support 500 will drive the material bin 600 and the lower pressing plate 700 to rotate synchronously.

[0039] In this embodiment, the rotary support 500 includes a rotary disc and three rotating arms. The rotary disc is of an annular structure, and the three rotating arms are evenly distributed on the rotary disc around the first direction. Each rotating arm is connected to the support disc 200 through a mating rotating frame 510. The mating rotating frame 510 is arranged along the second direction, and the second direction is the horizontal direction. One end of the mating rotating frame 510 along the second direction is rotatably connected to the support disc 200, and the other end of the mating rotating frame 510 along the second direction is rotatably connected to the rotating arm.

[0040] A first motor 110 is provided on the base 100. The first motor 110 can drive one of the mating rotating frames 510 to rotate around the first direction on the support disc 200, and further cause the rotary support 500 to revolve around the vertical central axis of the support disc 200 through the mating rotating frame 510.

[0041] In this embodiment, a driving rod 520 is provided on the rotary support 500. The driving rod 520 is arranged along the first direction and can rotate around its own axis. A driving arm 530 is sleeved on the driving rod 520. The driving arm 530 is in screw fit with the driving rod 520. And when the driving rod 520 rotates around its own axis, the driving arm 530 can move up and down. The driving arm 530 is fixedly connected to the lower pressing plate 700.

[0042] Specifically, a second motor is provided on the rotary support 500, and the second motor can cause the driving rod 520 to rotate around its own axis.

[0043] Further, the lower pressing plate 700 includes a cover shell and a pressing plate. The cover shell is fixedly connected to the driving arm 530 and is located above the pressing plate. The cover shell and the pressing plate are connected by a first elastic member. The first elastic member is arranged in the first direction and always has a tendency to urge the pressing plate to move downward. The first elastic member is a spring. A plurality of first elastic members are provided.

[0044] Furthermore, a plurality of arc-shaped convex strips are provided on the lower surface of the pressing plate.

[0045] In this embodiment, by providing the driving rod 520, when in use, the second motor is first started to make the driving rod 520 rotate around its own axis. The rotation of the driving rod 520 will cause the driving arm 530 to move on the driving rod 520, changing the distance between the pressing plate and the eucommia ulmoides leaves in the first direction, so that the pressing plate can contact the eucommia ulmoides leaves with a certain pressure. And as the kneading progresses, the volume of the eucommia ulmoides leaves in the bin 600 will continuously decrease. At this time, under the action of the first elastic member, the pressing plate will always contact the eucommia ulmoides leaves, and the distance between the pressing plate and the eucommia ulmoides leaves in the first direction is controlled by the first elastic member to adapt to the change in the volume of the eucommia ulmoides leaves, thereby providing continuous and stable pressure for the eucommia ulmoides leaves.

[0046] Or, in another possible embodiment, the lower pressing plate 700 is an integrally formed structure. A pressure sensor is provided at the lower end of the lower pressing plate 700. The pressure sensor can sense the pressure between the lower pressing plate 700 and the eucommia ulmoides leaves. The pressure sensor is electrically connected to the second motor. Furthermore, when the pressure sensor senses that the pressure between the lower pressing plate 700 and the eucommia ulmoides leaves is less than a preset value, the pressure sensor can drive the second motor to start, and drive the lower pressing plate 700 to move downward through the second motor, so that the lower pressing plate 700 can always contact the eucommia ulmoides leaves.

[0047] That is, as the kneading progresses, the volume of the eucommia ulmoides leaves in the bin 600 will continuously decrease, making the lower pressing plate 700 no longer able to contact the eucommia ulmoides leaves. However, through the cooperation of the pressure sensor and the second motor, the lower pressing plate 700 can adapt to the change in the volume of the eucommia ulmoides leaves, thereby providing continuous and stable pressure for the eucommia ulmoides leaves.

[0048] In this embodiment, the rotation direction of the rotary support 500 is opposite to the direction in which the spiral line of the kneading disc 300 is wound from the first end to the second end.

[0049] By making the two directions opposite, the kneading force on the eucommia ulmoides leaves is increased to a certain extent. Of course, the rotation direction of the rotary support 500 can also be the same as the winding direction of the spiral line of the kneading disc 300.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
