Technical Field

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

[0002] Eucommia gum is a natural polymer material extracted from the bark and leaves of Eucommia ulmoides, which has good wear resistance, tear resistance, corrosion resistance and excellent insulation properties. In the process of extracting Eucommia gum, the conventional separation method is to use biological enzymes to degrade the mesophyll of Eucommia ulmoides leaves to obtain the Eucommia gum fibers in the veins containing Eucommia gum. However, the biochemical reaction used for direct degradation by biological enzymatic hydrolysis is slow and very time-consuming.

[0003] Chinese patent CN218689966U discloses a Eucommia leaf kneading and separation machine, which sets a compacting chamber cover to cooperate with the kneading plate to make circular motion, so that the Eucommia leaves in the kneading chamber are continuously kneaded, thereby achieving the purpose of separating the leaf flesh from the leaf veins, and gradually rolling into a relatively intact ellipsoidal rubber ball. However, the Eucommia gum balling speed is slow during use, which reduces the overall production efficiency and prolongs the Eucommia gum extraction cycle. Summary of the invention

[0006] Furthermore, 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] Furthermore, a support tube is provided on the discharge pipe, the support tube is sleeved with the discharge pipe, and a hydraulic telescopic cylinder is provided between the discharge pipe and the support tube.

[0008] Furthermore, it also includes a rotating bracket, which is installed on the base. The rotating bracket is located above the kneading disk and can revolve around the vertical central axis of the support disk. The material bin is installed on the rotating bracket and can rotate with the rotating bracket.

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

[0010] Furthermore, a driving rod is provided on the rotating bracket. The driving rod is arranged along the first direction and can rotate around its own axis.

Under the promotion of the kneading plate's own structure, the number of Eucommia leaves in the silo close to the inner wall of the silo will be relatively increased, so that the Eucommia leaves close to the inner wall of the silo are kneaded for a longer path, which improves the efficiency of Eucommia gum agglomeration to a certain extent. The kneading plate with a vortex structure can also increase the friction between the Eucommia leaf and the kneading plate when they are in contact, and assist in the separation of Eucommia gum. The discharge ring is located above the support plate, so that the kneading plate is a conical structure with a small upper end and a large lower end, which can also avoid the Eucommia leaf that has not been completely separated from being discharged through the discharge port on the discharge ring, resulting in waste of Eucommia leaf.

[0016] After the eucommia gum is separated into agglomerates, the eucommia leaf kneading separator for eucommia gum extraction is in a discharging state, and the second end of the kneading disk will be located above the first end of the kneading disk, thereby making the kneading disk present a conical structure with a large upper end and a small lower end. In the process that the hopper and the lower pressure plate rotate around the vertical central axis of the support disk and drive the agglomerated eucommia gum to rotate, the agglomerated eucommia gum will not be discharged from the discharging port due to the restrictions of the lower pressure plate, the hopper and the kneading disk. The separated eucommia leaves can be discharged from top to bottom through the discharging ring along the inclined surface of the kneading disk, so as to prevent the separated eucommia leaves from adhering to the eucommia gum agglomerates again.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] An embodiment of a eucommia leaf rubbing separator for extracting eucommia gum of the present invention is as follows Figures 1 to 6 shown.

[0022] A Eucommia leaf kneading separator for extracting Eucommia gum comprises a base 100, a support plate 200, a kneading plate 300, a discharge ring 400, a silo 600 and a lower pressing plate 700. The support plate 200 is arranged along a first direction and fixedly mounted on the base 100, the first direction is a vertical direction, the kneading plate 300 is mounted on the support plate 200 and is coaxial with the support plate 200, the kneading plate 300 is a vortex structure, and the plane where its vortex line is located is a horizontal plane, the end located at the center of the vortex structure of the kneading plate 300 is the first end, the end located at the outermost circle of the vortex structure of the kneading plate 300 is the second end, and the first end is coaxial with the axis of the support plate 200.

[0023] The discharge ring 400 is coaxially arranged with the support disk 200, and a discharge port is provided on the discharge ring 400. The first end of the kneading disk 300 is fixedly connected to the discharge ring 400, and the second end is fixedly connected to the support disk 200. In the initial state, the discharge ring 400 and the support disk 200 are on the same horizontal plane. The silo 600 is installed on the base 100, and the silo 600 is located above the kneading disk 300 and can revolve around the vertical center axis of the support disk 200. The lower pressing plate 700 can be installed in the silo 600 so as to move up and down, and can rotate with the silo 600. A kneading space for kneading Eucommia ulmoides leaves is defined between the kneading disk 300, the silo 600 and the lower pressing plate 700. The Eucommia leaf kneading separator for extracting Eucommia gum has a kneading state and a discharging state. When in the kneading state, the discharging ring 400 is located above the supporting disk 200; when in the discharging state, the discharging ring 400 is located below the supporting disk 200.

[0024] Specifically, the silo 600 is a cylindrical silo, 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 discharge port is 30 cm. By setting a large diameter silo 600, the number of kilograms of Eucommia leaves that can be rubbed at a time is increased.

[0025] In this embodiment, a base 100, a support plate 200, a kneading plate 300, a discharge ring 400, a hopper 600 and a lower pressure plate 700 are arranged in coordination. In an initial state, the discharge ring 400 and the support plate 200 are located on the same horizontal plane. When in use, the Eucommia leaves to be kneaded are first placed in the hopper 600, and then the lower pressure plate 700 is moved downward to confine the Eucommia leaves in the kneading space defined by the kneading plate 300, the hopper 600 and the lower pressure plate 700.

[0026] When rubbing and separating the Eucommia leaves, the Eucommia leaf rubbing and separating machine for extracting Eucommia gum is in a rubbing state, that is, the discharge ring 400 is located above the support plate 200, see the attached Figure 3 As shown, since the first end of the kneading plate 300 is fixedly connected to the discharge ring 400, and the second end is fixedly connected to the support plate 200, the first end of the kneading plate 300 will be located above the second end of the kneading plate 300, so that the kneading plate 300 is a tapered structure with a small upper end and a large lower end, which will cause the Eucommia leaves in the silo 600 to move downward along the kneading plate 300 and approach the lower part of the kneading plate 300, and to a certain extent increase the number of Eucommia leaves close to the inner wall of the silo 600. That is, under the promotion of the structure of the kneading plate 300 itself, the number of Eucommia leaves in the silo 600 close to the inner wall of the silo 600 will be relatively increased.

[0027] Then, the hopper 600 is made to revolve around the vertical center axis of the support disk 200, and the hopper 600 will drive the lower pressure plate 700 to rotate synchronously to knead the Eucommia leaves in the hopper 600. Since the number of Eucommia leaves close to the inner wall of the hopper 600 is relatively increased, when the hopper 600 and the lower pressure plate 700 rotate to knead the Eucommia leaves, the Eucommia leaves close to the inner wall of the hopper 600 are kneaded over a longer path than the Eucommia leaves close to the vertical center axis of the hopper 600. As a result, when kneading the Eucommia leaves, the degree to which the Eucommia leaves are kneaded increases relatively every time the hopper 600 and the lower pressure plate 700 rotate around the vertical center axis of the support disk 200, thereby improving the efficiency of Eucommia gum agglomeration to a certain extent. The rubbing plate 300 with a vortex structure can also increase the friction between the Eucommia leaves and the rubbing plate 300, thereby assisting in the separation of Eucommia gum. The discharge ring 400 is located above the support plate 200, so that the rubbing plate 300 has a conical structure with a small upper end and a large lower end. This can also prevent the Eucommia leaves that have not been completely separated from being discharged through the discharge port on the discharge ring 400, resulting in waste of Eucommia leaves.

[0028] After the eucommia gum is separated into agglomerates, the eucommia leaf kneading separator for extracting eucommia gum is placed in a discharging state, that is, the discharging ring 400 is located below the supporting plate 200, see the attached Figure 5 As shown, at this time, the second end of the kneading disk 300 will be located above the first end of the kneading disk 300, thereby making the kneading disk 300 present a conical structure with a large upper end and a small lower end. In the process that the hopper 600 and the lower pressure plate 700 rotate around the vertical center axis of the support disk 200 and drive the agglomerated Eucommia gum to rotate, the agglomerated Eucommia gum will not be discharged from the discharge port due to the restriction of the lower pressure plate 700, the hopper 600 and the kneading disk 300. The separated Eucommia leaves can be discharged from the discharge port on the discharge ring 400 from top to bottom along the inclined surface of the kneading disk 300, so as to avoid the separated Eucommia leaves from adhering to the Eucommia gum agglomerates again, thereby improving work efficiency.

[0029] 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.

[0030] Furthermore, a support tube 420 is provided on the discharge pipe 410 , the support tube 420 is sleeved with the discharge pipe 410 , and a hydraulic telescopic cylinder 430 is provided between the discharge pipe 410 and the support tube 420 .

[0031] In this embodiment, the discharge pipe 410 is provided, and the Eucommia leaves falling from the discharge port of the discharge ring 400 can be discharged through the discharge pipe 410. In addition, a support cylinder 420 is provided on the discharge pipe 410, and the support cylinder 420 is installed on the ground when in use. The hydraulic telescopic cylinder 430 is started to drive the discharge pipe 410 to move up and down relative to the support cylinder 420, and then the discharge ring 400 is driven to move up and down through the discharge pipe 410, so that the Eucommia leaf kneading separator for extracting Eucommia gum is switched between the kneading state and the discharge state.

[0032] In this embodiment, a Eucommia leaf kneading separator for extracting Eucommia gum also includes a rotating bracket 500, which is installed on a base 100. The rotating bracket 500 is located above the kneading disk 300 and can revolve around the vertical center axis of the support disk 200. The silo 600 is installed on the rotating bracket 500 and can rotate with the rotating bracket 500.

[0033] By providing the swivel bracket 500 , the swivel bracket 500 is made to revolve around the vertical center axis of the support plate 200 during use. The rotation of the swivel bracket 500 will drive the silo 600 and the lower pressure plate 700 to rotate synchronously.

[0034] In this embodiment, the rotating bracket 500 includes a rotating disk and three rotating arms. The rotating disk is a ring structure. The three rotating arms are evenly distributed on the rotating disk around the first direction. Each rotating arm is connected to the supporting disk 200 through a matching rotating frame 510. The matching rotating frame 510 is arranged along the second direction, and the second direction is a horizontal direction. One end of the matching rotating frame 510 along the second direction is rotatably connected to the supporting disk 200, and the other end of the matching rotating frame 510 along the second direction is rotatably connected to the rotating arm.

[0035] A first motor 110 is disposed on the base 100 , and the first motor 110 can drive one of the mating rotating frames 510 to rotate around a first direction on the support plate 200 , thereby causing the swivel bracket 500 to revolve around the vertical center axis of the support plate 200 through the mating rotating frame 510 .

[0036] In this embodiment, a driving rod 520 is provided on the rotating bracket 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 spirally matched 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 pressure plate 700.

[0037] Specifically, a second motor is disposed on the swivel bracket 500 , and the second motor can make the driving rod 520 rotate around its own axis.

[0038] 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 via a first elastic member, the first elastic member is arranged along a first direction, and the first elastic member always has a tendency to cause the pressing plate to move downward. The first elastic member is a spring. A plurality of first elastic members are provided.

[0039] Furthermore, a plurality of arc-shaped convex strips are arranged on the lower surface of the pressing plate.

[0040] In this embodiment, a driving rod 520 is set. When in use, the second motor is started first to rotate the driving rod 520 around its own axis. The rotation of the driving rod 520 will prompt the driving arm 530 to move on the driving rod 520, changing the distance between the clamping plate and the Eucommia leaves in the first direction, so that the clamping plate can contact the Eucommia leaves with a certain pressure, and as the kneading proceeds, the volume of the Eucommia leaves in the silo 600 will continue to shrink. At this time, under the action of the first elastic member, the clamping plate will always be in contact with the Eucommia leaves, and the distance between the clamping plate and the Eucommia leaves in the first direction is controlled by the first elastic member to adapt to the change in the volume of the Eucommia leaves, thereby providing continuous and stable pressure for the Eucommia leaves.

[0041] Alternatively, in another possible embodiment, the lower pressure plate 700 is an integrally formed structure, and a pressure sensor is provided at the lower end of the lower pressure plate 700. The pressure sensor can sense the pressure between the lower pressure plate 700 and the Eucommia leaves. The pressure sensor is electrically connected to the second motor, so that when the pressure sensor senses that the pressure between the lower pressure plate 700 and the Eucommia leaves is less than a preset value, the pressure sensor can drive the second motor to start, and drive the lower pressure plate 700 to move downward through the second motor, so that the lower pressure plate 700 can always be in contact with the Eucommia leaves.

[0042] That is, as the kneading proceeds, the volume of the Eucommia leaves in the silo 600 will continue to shrink, so that the lower pressure plate 700 can no longer contact the Eucommia leaves. Through the cooperation of the pressure sensor and the second motor, the lower pressure plate 700 can adapt to the changes in the volume of the Eucommia leaves, thereby providing continuous and stable pressure for the Eucommia leaves.

[0043] In this embodiment, the rotation direction of the swivel bracket 500 is opposite to the direction in which the spiral line of the kneading plate 300 is wound from the first end to the second end.

[0044] By making the two directions opposite to each other, the kneading force on the Eucommia leaves is increased to a certain extent. Of course, the rotation direction of the rotating bracket 500 can also be made the same as the winding direction of the spiral line of the kneading disk 300.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
