Description

Technical Field

[0001] The invention relates to the field of essential oil production equipment, in particular to a raw material placement rack for essential oil processing. Background Art

[0002] The raw materials of essential oils mainly come from spice plants or aromatic animals. Specifically, essential oils are volatile aromatic substances extracted from the flowers, leaves, roots, seeds, fruits, barks, resins, wood cores and other parts of plants through steam distillation, cold pressing, liposorption or solvent extraction. These raw materials include flower raw materials, such as rose, jasmine, orange blossom, chamomile, rosemary, lavender, etc., which usually have calming, soothing and relaxing effects. In addition, tree raw materials are also common essential oil raw materials, such as pine, cypress, eucalyptus, fir, sandalwood, etc., which usually have bactericidal, disinfecting and anti-inflammatory effects.

[0003] The existing storage rack has a simple structure. Since the extraction ratio of essential oils is very low, the consumption of raw materials is large. Vertical storage of raw materials can save storage space, but baskets of raw materials need to be lifted and placed on the shelves. Although the weight of raw petals is not large, the large amount of raw petals consumes a lot of physical energy of the staff, and when the lifting height is too high, the center of gravity of the staff may be unstable, so the placement process is more difficult; when producing essential oils, baskets of raw petals need to be poured into the conveyor, and then the conveyor transports the raw materials for processing. At this time, the raw materials on the storage rack need to be moved down and poured into the conveyor for subsequent processing. Under long-term repetitive operation, the efficiency will also be reduced as the physical energy is consumed. Summary of the invention

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0028] Embodiment: A raw material placement rack for essential oil processing, such as Figure 1-Figure 5As shown, it includes a placement frame 0, a connecting base 1, a supporting side plate 11, a connecting frame 12, a motor 2, a sprocket 21, a chain 22, a pipe sleeve 23, a sliding frame 24, a roller 241, a placement bottom plate 25, a rotating top plate 26 and a fixing component. A universal wheel is arranged at the bottom of the connecting base 1, and supporting side plates 11 are fixedly connected to both sides of the top of the connecting base 1. The connecting frame 12 is fixedly connected to the front end of the supporting side plate 11 and is used to connect two supporting side plates 11. Parallel guide rails 13 are respectively arranged on the facing surfaces of the two supporting side plates 11. The side edges of the supporting side plates 11 are equipped with motors 2. The upper and lower parts of the facing surfaces of the two supporting side plates 11 are rotatably connected with sprockets 21. The sprockets 21 on the same side are jointly sleeved with a chain 22. The two sprockets 21 at the upper ends are connected by a rotating shaft. The rotating shaft of the sprocket 21 passes through the supporting side plate 11. The output shaft of the motor 2 is connected to a sprocket 21 at the lower end. A pipe sleeve 23 is installed on the chain 22. A sliding frame 24 is sleeved in the pipe sleeve 23, and the sliding frame 24 is slidably connected to the parallel guide rails 13. Each convex rod of the sliding frame 24 has a fixed track, and the tracks are parallel to each other. Both ends of the placement base plate 25 are fixedly connected to the sliding frame 24, and each convex rod of the sliding frame 24 is sleeved with a roller 241. The roller 241 changes the sliding friction between the sliding frame 24 and the supporting side plate 11 into rolling friction, so that the sliding frame 24 is smoother when moving. A rotating top plate 26 is rotatably connected to the placement base plate 25, and the rotating top plate 26 rotates around the round rod. The round rod passes through both sides of the placement base plate 25, and the placement frame 0 is placed on the rotating top plate 26. With the round rod as the boundary, the length of the front end of the rotating top plate 26 is greater than the rear end, and the rotating top plate 26 can only rotate backward, so that the force arm of the rear end is shorter, and the rotating top plate 26 itself cannot rotate. A fixing component for fixing the placement frame 0 is provided on the rotating top plate 26.

[0029] like Figure 6 and Figure 7 As shown, the fixed assembly includes a limiting base plate 3, a limiting frame 31, a guide frame 32 and an elastic member 33. The limiting base plate 3 is fixedly connected to the left and right sides of the placement frame 0, and the guide frame 32 is fixedly connected to the front and rear sides of the rotating top plate 26. The outer end of the limiting frame 31 is slidably connected to the guide frame 32, and the inner end of the limiting frame 31 is slidably connected to the limiting base plate 3. The outer end of the limiting frame 31 is sleeved with an elastic member 33, one end of the elastic member 33 is connected to the guide frame 32, and the other end is connected to the limiting frame 31. When the limiting frame 31 moves outward, it will compress the elastic member 33, and at the same time, the limiting frame 31 will also translate along the guide frame 32 to maintain a stable position. The compressed elastic member 33 will always push the limiting frame 31 to move toward the middle, and the length of the groove is much greater than the failure length of the elastic member 33 after deformation, so the deformation of the elastic member 33 can be ignored.

[0030] After the staff has processed the essence raw materials to be stored, they are loaded into the placement frame 0, and then the placement frame 0 containing the raw materials is placed on the rotating top plate 26. Since the rotating top plate 26 can only be rotated backward 90 degrees, and the length of the rotating top plate 26 at the rear end of the round rod is shorter than the distance at the front end, the force arm at the rear end is shorter, and the rotating top plate 26 itself cannot rotate. Moreover, before the placement frame 0 contacts the rotating top plate 26, the limiting bottom plates 3 on both sides of the placement frame 0 contact the limiting frames 31. Since the top of the limiting frames 31 is an inclined surface, it will squeeze the limiting frames 31 to move to both ends. When the limiting frames 31 move, the elastic member 33 is compressed. The compressed elastic member 33 always pushes the limiting frame 31 to move to the middle, so that the limiting frame 31 is close to the limiting bottom plate 3, and then the placement frame 0 and the limiting bottom plate 3 are placed. The plate 3 descends until the limiting bottom plate 3 is stuck in the groove at the bottom of the limiting frame 31. When the limiting bottom plate 3 is completely aligned with the limiting frame 31, the elastic member 33 rebounds and pushes the limiting frame 31 to clamp the limiting bottom plate 3 through the groove. If the limiting frame 31 does not move when the placement frame 0 contacts the rotating top plate 26, the placement frame 0 is pushed back and forth to align the limiting bottom plate 3 with the groove at the bottom of the limiting frame 31, thereby completing the fixation of the placement frame 0. Subsequently, the motor 2 is turned on, and the motor 2 drives a sprocket 21 at the lower end to rotate, and then the sprocket 21 drives the upper sprocket 21 to rotate through the chain 22, and the upper sprocket 21 drives the chain 22 on the other side to rotate through the rotating shaft. Since the sprocket 21 and the chain 22 will not slide out of position, all the sprockets 21 can be fixed. The chain 22 rotates simultaneously, and the chain 22 drives the pipe sleeve 23 to rotate. At the same time, the sliding frame 24 slides along the parallel guide rails 13 in the supporting side plate 11, so that the placement bottom plate 25 keeps moving in a horizontal state. When the fixed placement frame 0 leaves, the motor 2 is turned off, and the placement frame 0 filled with raw materials is placed on the empty rotating top plate 26. The placement bottom plate 25 is driven by the motor 2 to rotate, so that the horizontal height of the placement bottom plate 25 is at a comfortable height for a worker to carry, thereby saving manpower. At the same time, there is no need to put the placement frame 0 at a high place to ensure safety during transportation. When all the rotating top plates 26 are placed with placement frames 0, the universal wheel is unlocked, so that the supporting side plates 11 can be pushed to move as a whole. The arrangement and placement can reduce the space used, and the locking The universal wheel is used to push the whole body when raw materials are needed for production, so that the rear end of the supporting side plate 11 is located at the front end of the production equipment, so that the placement frame 0 is manually turned over, and the limiting bottom plate 3 connected to the placement frame 0 pulls the limiting frame 31, and the limiting frame 31 pulls the rotating top plate 26, so that the rotating top plate 26 rotates backward 90 degrees around the round rod on the placement bottom plate 25, and the raw materials in the placement frame 0 are dumped. After the raw materials are dumped, the placement frame 0 is flipped over to reset, and other placement frames 0 are moved by the motor 2 to dump the raw materials in all the placement frames 0. When the placement frame 0 needs to be removed, the rotating top plate 26 is flipped over to tilt it at a certain angle, and then the limiting frames 31 on both sides are pulled open to disengage the limiting bottom plate 3 from the grooves of the limiting frames 31, so that the placement frame 0 is removed.

[0031] like Figure 6-Figure 8 As shown, it also includes a cross block 4, a mounting frame 41, a gear 42, a top block 43, a rack 44 and a pull rod 45. The cross block 4 is fixedly connected to the left and right sides of the round rod of the rotating top plate 26, the mounting frame 41 is fixedly connected to the rear end of the supporting side plate 11, the middle of the mounting frame 41 is rotatably connected with the gear 42, the upper and lower parts of the mounting frame 41 are slidably connected with the top block 43, the lower end of the upper top block 43 is fixedly connected with the rack 44, the upper end of the lower top block 43 is fixedly connected with the rack 44, both racks 44 are meshed with the gear 42, the rear end of the upper top block 43 is fixedly connected with the pull rod 45, the upper part of the mounting frame 41 has two bayonet holes 451, the pull rod 45 is rotatably connected with a pulling handle, the handle is slidably connected to the bayonet hole 451, and the top block 43 is slidably connected to the cross block 4.

[0032] like Figure 5 and Fig. 9 As shown, it also includes a fixed block 5, a connecting rod 51, a torsion spring 52, a buffer rod 53 and a buffer pad 531. A plurality of fixed blocks 5 are fixedly connected to the rear end of the base plate 25. The fixing blocks 5 are rotatably connected with connecting rods 51. The buffer rod 53 is fixedly connected to the connecting rod 51. The buffer pad 531 is connected to the rear end of the buffer rod 53. A torsion spring 52 is sleeved on the connecting rod 51. One end of the torsion spring 52 is connected to the fixed block 5, and the other end is connected to the buffer rod 53.

[0033] When dumping the raw materials, the motor 2 is directly turned on to make the placement frame 0 at the bottom rotate backward. At this time, the cross block 4 fixed on the round rod of the rotating top plate 26 contacts with the top block 43. Since the top block 43 is located at the rear side of the cross block 4, the cross block 4 will rotate backward around the round rod after being squeezed by the top block 43, thereby driving the rotating top plate 26 to rotate backward 90 degrees, completing the dumping of the placement frame 0 and directly pouring out the raw materials. In addition, during the rotation of the rotating top plate 26, the bottom of the rear end contacts with the buffer pad 531, thereby squeezing the buffer rod 53 to rotate around the connecting rod 51, and at the same time twisting the torsion spring 52 to buffer the speed of the rotating top plate 26 rotating 90 degrees, so that it will not violently collide with the placement frame due to inertia. The bottom plate 25 collides, and because the cross block 4 must rotate 90 degrees, the rotating top plate 26 can still rotate 90 degrees in the end, and the placement frame 0 completes the dumping of the raw materials. Then the connecting frame 12 continues to move upward, and the cross block 4 contacts the top block 43 again after rotating 90 degrees. At this time, the top block 43 is located at the front end of the cross block 4, so the cross block 4 rotates forward 90 degrees, driving the rotating top plate 26 and the placement frame 0 to rotate and reset. When the rotating top plate 26 leaves the buffer pad 531, the torsion spring 52 twists back to make the buffer rod 53 rotate upward to complete the reset. The next placement frame 0 completes the dumping of the raw materials through the above steps. When all placement frames 0 have completed the dumping of the raw materials, the motor 2 is turned off.

[0034] like Figure 1 and Fig.10As shown, it also includes a hanging frame 6, a shielding cloth 61 and a hanging plate 611. The hanging frame 6 is fixedly connected to the front end of the base plate 25. One end of the shielding cloth 61 is mounted on the hanging frame 6, and the other end is connected to the hanging plate 611. The hanging plate 611 is placed on the hanging frame 6.

[0035] If the raw materials need to be placed for a period of time, after the placement frame 0 is fixed, the shielding cloth 61 is pulled up, and the hanging plate 611 is passed through the top of the placement frame 0 and placed on the rear side of the placement frame 0. Since the hanging plate 61 has a certain weight, the shielding cloth 61 will not fall off after covering the placement frame 0, and when pouring the raw materials, the opening of the placement frame 0 rotates from the bottom of the shielding cloth 61, and the shielding cloth 61 can only cover the top surface of the front side of the placement frame 0. Therefore, when the placement frame 0 is poured, the opening rotates to the rear end, and the shielding cloth 61 cannot affect the pouring. Moreover, when the placement frame 0 is reset, the placement frame 0 rotates forward, and the tenon edge at the opening of the placement frame 0 will push the hanging plate 61 to rotate, and finally fall onto the suspension frame 6, completing the folding of the shielding cloth 61.

[0036] like Figure 1 and Fig.11 As shown, it also includes a long rod 7, an upper rod 71, a lower rod 72 and a support frame 73. The long rod 7 and the lower rod 72 are fixedly connected to the left and right sides of the connecting base 1, the lower rod 72 is located behind the long rod 7, and the upper rod 71 is fixedly connected to the supporting side plate 11. The upper rod 71 is located above the long rod 7. The bottom of the support frame 73 is sleeved on the long rod 7, and a round hole is opened in the middle, which is slidably connected to the upper rod 71 and the lower rod 72.

[0037] When pouring the raw materials, the inclined placement frame 0 causes the overall center of gravity to shift, so that the support frame 73 is pulled out to both sides before pouring, the support frame 73 slides on the long rod 7 and the upper rod 71, leaves the upper rod 71, and is rotated and lowered, and then the support frame 73 is pushed toward the middle, and the support frame 73 slides toward the middle along the long rod 7 and the lower rod 72, thereby limiting the support frame 73 from rotating. The bottom of the support frame 73 contacts the ground, thereby increasing the support of the rear end and making the pouring of the raw materials more stable. After all the placement frames are poured, the support frame 73 is pulled out from the lower rod 72, rotated upward 90 degrees, and reinserted into the upper rod 71 for fixing without affecting the overall movement.

[0038] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
