DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figure 1-11As shown, the utility model discloses a vertical oscillation device, including a vertical oscillation mechanism 1 and a pipe rack 2. The vertical oscillation mechanism 1 includes a power unit 11, a flywheel 12, a balance block 13, and two guide units 14 arranged on both sides of the flywheel 12. The two guide units 14 each include a slide rail seat 141, a guide slider 142, an eccentric shaft and a roller bearing follower 143. The guide slider 142 is slidably connected to the side of the slide rail seat 141 away from the flywheel 12 along the vertical direction, and a guide groove 1421 is provided on the side wall surface of the guide slider 142. The center lines of the eccentric shaft and the bearing follower 143 are both arranged horizontally. The bearing follower 143 is fixedly connected to the eccentric shaft and is rotatably arranged in the guide groove 1421.

[0035] The tube rack 2 includes a frame body 21, which is fixedly connected to a guide slider 142 of one of the guide units 14, and a tube bin 211 for placing the sample tube 6 is provided on the frame body 21, and a bin opening 2111 is provided on the top of the tube bin 211 for the sample tube 6 to enter and exit. The balance block 13 is fixedly connected to the guide slider 142 of the other guide unit 14. By connecting the frame body 21 and the balance block 13 respectively through the relatively arranged guide units 14, the center of gravity of the device can be adjusted to approach the middle part, and the center of gravity can be lowered at the same time, effectively enhancing the stability and balance of the overall structure of the device.

[0036] The power unit 11 is used to drive the flywheel 12 and the eccentric shafts in the two guide units 14 to rotate synchronously. The power unit 11 specifically includes a servo motor 111, a first synchronous wheel 112, a second synchronous wheel 113, a transmission shaft 114 and a synchronous belt 115. The servo motor 111 is fixedly connected to the slide rail seat 141, the first synchronous wheel 112 is drivingly connected to the servo motor 111, the second synchronous wheel 113 is arranged between the slide rail seats 141, the transmission shaft 114 horizontally passes through the flywheel 12, the second synchronous wheel 113 and the slide rail seats 141 in the two guide units 14, and the eccentric shafts in the two guide units 14 are fixedly arranged at both ends, and the synchronous belt 115 is wound around the outside of the first synchronous wheel 112 and the second synchronous wheel 113.

[0037] The flywheel 12, the second synchronous wheel 113 and the eccentric shaft are all fixedly connected to the transmission shaft 114, and the transmission shaft 114 is rotatably connected to the slide rail seat 141 through a bearing. When the servo motor 111 is turned on, the transmission shaft 114 can be driven to rotate by the first synchronous wheel 112, the second synchronous wheel 113 and the synchronous belt 115, thereby driving the flywheel 12 fixedly connected to the transmission shaft 114 and the eccentric shaft to rotate synchronously. After the eccentric shaft rotates, the bearing follower 143 fixedly mounted on the eccentric shaft rotates in the guide groove 1421, which can guide the guide slider 142 and the pipe rack 2 and the balance block 13 fixedly connected to the guide slider 142 to perform vertical reciprocating motion, so as to achieve the purpose of vertical oscillation of the sample. During the oscillation process, most of the motion inertia can be balanced by the balance block 13 and the flywheel 12, which enables the device to maintain stability and balance under high-frequency oscillation, thereby ensuring the sample oscillation effect.

[0038] Corresponding to the power unit 11, the vertical oscillation mechanism 1 is provided with a servo mounting plate and at least two reinforcing ribs 16. The servo mounting plate is located between the slide rail seats 141 and is fixedly connected to the side wall surface of one of the slide rail seats 141. The servo motor 111 is fixedly connected to the side of the servo mounting plate and is located directly above the guide unit 14, and the first synchronous wheel 112 is correspondingly arranged on the other side of the servo mounting plate. The reinforcing ribs 16 are vertically arranged on both sides of the servo motor 111, and the sides of the reinforcing ribs 16 are fixedly connected to the servo mounting plate, and the bottom is fixedly connected to the slide rail seat 141, which can strengthen the connection between the servo mounting plate and the slide rail seat 141 and improve the overall stability of the equipment.

[0039] In order to further reduce the inertia of the equipment during operation, a balancing cylinder 4 is fixedly arranged below the vertical oscillation mechanism 1. The balancing cylinder 4 has a retractable piston rod 41, which is arranged vertically, and the end of which is against the bottom of the guide slider 142. During vertical oscillation, the balancing cylinder 4 can effectively offset the weight of the tube rack 2, the sample tube 6 and the sample through the pushing effect of the balancing cylinder 4, thereby reducing the load and inertia of the servo motor 111. The thrust of the balancing cylinder 4 can be adjusted by controlling the air pressure of the balancing cylinder 4.

[0040] At the same time, a damping mechanism 5 is fixedly arranged below the vertical oscillation mechanism 1. The damping mechanism 5 includes an upper plate 51, an intermediate plate 52 and a lower plate 53 arranged in sequence from top to bottom, and also includes a plurality of damping springs 54. The upper plate 51, the intermediate plate 52 and the lower plate 53 are arranged in parallel, and a damping spring 54 is vertically arranged on the top surface of each of the three plates, and the three plates are connected and fixed to each other through the damping spring 54. The damping spring 54 includes a first damping spring 541 and a second damping spring 542. The first damping spring 541 and the second damping spring 542 are rectangular springs of different models and are arranged alternately up and down. A plurality of damping rubber pads 55 are fixedly connected to the bottom of the lower plate 53. The first damping spring 541, the second damping spring 542 and the damping rubber pad 55 are used to reduce vibration step by step, which can basically consume the remaining motion inertia after the flywheel 12 absorbs energy.

[0041] In addition, in order to ensure the stable placement of the sample tube 6 during the oscillation process, a tube pressing mechanism 3 is also arranged above the vertical oscillation mechanism 1. The tube pressing mechanism 3 includes a support seat 31, a linear guide rail 32, a sliding seat 33, a guide rod 34, a compression spring 35 and a driving device 36. The support seat 31 is fixedly arranged above the slide rail seat 141, and the sliding seat 33 is slidably connected above the support seat 31 through the linear guide rail 32, and the sliding direction is inclined. A guide through hole is vertically opened on the sliding seat 33, and a self-lubricating bushing is installed in the guide through hole. The guide rod 34 is vertically arranged above the port 2111 and moves through the guide through hole.

[0042] The upper end of the guide rod 34 is fixedly provided with an upper limit ring 341, and the lower end is fixedly provided with a lower limit ring 342, so as to limit the guide rod 34 and prevent the guide rod 34 from slipping out of the guide through hole. Preferably, the upper limit ring 341 and / or the lower limit ring 342 are detachably fixed to the guide rod 34 using an open type fixing ring, so as to adjust the length of the guide rod 34 to move up and down.

[0043] The compression spring 35 is arranged below the sliding seat 33 and sleeved on the outside of the guide rod 34. The upper and lower ends of the compression spring 35 respectively abut against the sliding seat 33 and the lower limit ring 342. Through the rebound effect of the compression spring 35, the guide rod 34 can be pushed down to press the sample tube 6 placed in the tube bin 211, and the sample tube 6 is pressed and fixed in the tube bin 211. The driving device 36 is fixedly connected to the support seat 31 and is drivingly connected to the sliding seat 33, and is used to drive the sliding seat 33 to slide along the linear guide rail 32, thereby driving the guide rod 34 on the sliding seat 33 to tilt up and down, and then approach or move away from the top of the bin opening 2111.

[0044] Since it is often necessary to perform vertical oscillation treatment on samples in multiple sample tubes 6 at the same time, the guide rods 34 and the tube bins 211 are each provided with a plurality of guide rods 34, and the guide rods 34 and the tube bins 211 are provided one by one. In this case, the tube pressing mechanism 3 is additionally provided with a tube pressing cross bar 37, which is located below the lower limit ring 342, and the lower ends of the guide rods 34 respectively pass through the tube pressing cross bar 37 and are fixedly connected to the tube pressing cross bar 37. Through the tube pressing cross bar 37, the expansion and contraction directions of the compression springs 35 can be consistent, and the thrust is uniform.

[0045] In addition to the additional tube pressing mechanism 3, the device is also provided with a plurality of tension springs 22. The tension spring 22 is arranged above the port 2111 in a stretched state, and the two ends are respectively fixedly connected to the frame 21. After the sample tube 6 is loaded into the tube bin 211, the sample tube 6 can be pressed and fixed on the side wall of the tube bin 211, which enables the tube bin 211 to adapt to sample tubes 6 of various sizes and specifications, thereby improving the compatibility and versatility of the device. In addition, the tube bin 211 adopts a semi-open structure, and a positioning hole 2112 is also provided at the bottom center of the tube bin 211. The aperture of the positioning hole 2112 is smaller than the outer diameter of the sample tube 6. While supporting and positioning the sample tube 6, the contact area with the bottom of the sample tube 6 can be reduced, thereby reducing the plane projection area of ​​the oscillation.

[0046] Working process: Before using the equipment, a certain amount of organic solvent can be added to the sample tube 6 through a manual or automatic liquid adding module, and the homogenizer for grinding can be added through a manual or automatic homogenizer adding module. After the organic solvent and the homogenizer are added, the sample tube 6 can be placed in the tube warehouse 211. After the sample tube 6 is placed, the tube pressing mechanism 3 is triggered to press down and fix the sample tube 6, and a pressing completion signal is sent to the vertical oscillation mechanism 1. After receiving the pressing completion signal, the vertical oscillation mechanism 1 will automatically operate according to the set frequency and time, driving the flywheel 12, the balance block 13, the tube rack 2 and the sample tube 6 to perform vertical reciprocating motion until the sample is broken to achieve the oscillation extraction effect.

[0047] During the oscillation process, the device will vibrate greatly, but the circular motion of the flywheel 12 can balance about 70% of the motion inertia, and the remaining 30% of the motion inertia can be basically offset by the vibration reduction mechanism 5 at the bottom of the device. The vibration reduction mechanism 5 adopts a three-layer structure and is provided with a first vibration reduction spring 541 and a second vibration reduction spring 542 of different types. When the mechanical vibration is transmitted to the middle plate 52, 95% of the mechanical vibration can be filtered out, and the remaining mechanical vibration is reduced by the lower plate 53 and the vibration reduction rubber pad 55 thereunder.

[0048] Based on its superior energy absorption characteristics and stable structure, the device can achieve stable operation of any parameters under the wide frequency oscillation conditions of 300-1350 times / minute through multi-end acceleration and deceleration control, meeting the user's high-frequency oscillation needs.

[0049] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes in form and details of the present invention are within the scope of protection of the present invention without departing from the spirit and scope of the present invention as defined in the appended claims.
