Description

Technical Field

[0001] This utility model relates to the field of shaker technology, specifically to a constant temperature rotating shaker that can automatically replace sample vials. Background Technology

[0002] Tilting oscillators have wide applications in environmental protection, petrochemicals, pharmaceuticals, soil, air, and heavy metal pollution analysis, as well as in scientific research. Due to the special characteristics of environments such as soil, atmosphere, and petroleum, some scientific research or experiments cannot be conducted directly in these environments and must be simulated using corresponding equipment. In the laboratory, chemical analysis of various substances or extraction experiments of hazardous substances require that the sample be placed in a sample bottle, sealed, and then oscillated to simulate the objective conditions of biological or chemical reactions under natural and extreme conditions before analysis or extraction can be performed.

[0003] Most existing oscillators are open structures, which cannot process samples in a constant temperature environment. On the other hand, most constant temperature oscillators are closed, which requires frequent opening of the chamber door to manually change sample vials when processing a large number of samples, resulting in cumbersome operation and low sample processing efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a constant temperature inverted shaker that can automatically replace sample vials.

[0005] The technical solution of this utility model is: a constant temperature type rotating shaker that can automatically replace sample bottles, including a housing, a rotating cylinder arranged in the housing in a horizontal rotation, and an adding mechanism arranged above the rotating cylinder for adding sample bottles.

[0006] The inside of the flipping cylinder is provided with a partition plate, and the partition plate is provided with a plurality of first placement holes for placing sample bottles. Each first placement hole is provided with a clamping mechanism for holding the sample bottle. The cover plate of the flipping cylinder is provided with a plurality of second placement holes corresponding one-to-one with the first placement holes.

[0007] The housing is provided with a flipping motor for driving the flipping cylinder to rotate, and an inclined plate for receiving the sample bottle is inclined on the inner side wall of the housing, and an opening communicating with one side of the inclined plate is provided on the housing.

[0008] The tilting cylinder is equipped with a temperature sensor and an electric heating element, and the housing is equipped with a PLC controller. The temperature sensor and the electric heating element are electrically connected to the PLC controller.

[0009] Note: The above-mentioned shaker controls the temperature inside the rotating cylinder in real time through an electric heating tube and a temperature sensor. After a batch of samples is processed, the rotating cylinder can be rotated to allow the sample bottles to fall out of the rotating cylinder. The adding mechanism can automatically add new sample bottles into the rotating cylinder, avoiding manual replacement of sample bottles. The operation is simple and improves the sample processing efficiency.

[0010] Furthermore, the adding mechanism includes two lead screws arranged horizontally above the tilting cylinder, a feeding tube arranged vertically between the two lead screws for adding sample bottles into the tilting cylinder, and a movable plate sleeved on the feeding tube and threadedly connected to the two lead screws.

[0011] The two lead screws are respectively arranged on both sides of the tilting cylinder, and both ends of the lead screws are rotatably connected to the side wall of the housing. One end of the lead screw is provided with a drive mechanism for driving its rotation. A rotating shaft is vertically and rotatably arranged on the movable plate located on one side of the feed tube. A rotating disk is fixedly sleeved on both ends of the rotating shaft. One side of each of the two rotating disks extends into the feed tube for closing the feed tube. Each rotating disk is provided with a notch for intermittently opening the feed tube by rotating it, and the notches of the two rotating disks are staggered.

[0012] A rack parallel to a lead screw is provided below it. The rack is fixedly connected to the housing, and a gear that meshes with the rack is fixedly sleeved on the rotating shaft.

[0013] Multiple first placement holes are equally spaced, and the distance between adjacent first placement holes is equal to the circumference of the gear.

[0014] Explanation: The adding mechanism drives the lead screw to rotate, causing the movable plate to move along the lead screw. As the gear follows the movable plate, it drives the rotating shaft to rotate, allowing the two rotating discs to open the feeding tube in sequence, so that the sample bottle is automatically added from the feeding tube into the tilting cylinder.

[0015] Furthermore, both ends of the lead screw are rotatably connected to the side wall of the housing via connecting plates, and one end of the lead screw passes through the connecting plate;

[0016] The drive mechanism includes first pulleys fixedly sleeved on one end of two lead screws, and a motor fixedly mounted on the housing; the output shaft of the motor is provided with a second pulley for connecting to the two first pulleys via a transmission belt.

[0017] Explanation: The drive mechanism drives the second pulley to rotate via a motor, which in turn drives the first pulley to rotate via a transmission belt, and the first pulley drives the lead screw to rotate.

[0018] Furthermore, a hopper is provided above the feeding pipe.

[0019] Note: The hopper facilitates the addition of sample vials into the downward feed tube, and it is inexpensive to manufacture and highly practical.

[0020] Furthermore, the clamping mechanism includes multiple sets of two pneumatic rods respectively disposed on both sides of each first placement hole, and arc-shaped clamping pieces respectively disposed on the two pneumatic rods for clamping the sample bottle;

[0021] An air pump is installed on the partition, and the air pump is connected to each air pressure rod through a pipe.

[0022] Note: The air pump can inflate the air pressure rods, causing the two air pressure rods to extend and push the two arc-shaped clamps together to hold the sample bottle and prevent it from falling off during shaking.

[0023] The beneficial effects of this utility model are:

[0024] (1) The oscillator of this utility model controls the temperature inside the rotating cylinder in real time through the electric heating tube and temperature sensor. After a batch of samples is processed, the rotating cylinder can be rotated so that the sample bottle falls out of the rotating cylinder. The adding mechanism can automatically add new sample bottles into the rotating cylinder, avoiding manual replacement of sample bottles. The operation is simple and the sample processing efficiency is improved.

[0025] (2) When the arc-shaped clip of this utility model holds the sample bottle, the air pump can simultaneously inflate the annular airbag, so that the annular airbag is inflated to seal the gap between the sample bottle and the second placement hole, thereby improving the airtightness of the flipping cylinder and reducing the heat loss inside the flipping cylinder.

Detailed Implementation

[0034] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0035] Example 1:

[0036] like Figure 1 As shown, a constant temperature tilting shaker with automatic sample bottle replacement includes a housing 1, a tilting cylinder 2 that is laterally rotated inside the housing 1, and an adding mechanism 3 that is disposed above the tilting cylinder 2 for adding sample bottles.

[0037] like Figure 3 , Figure 4 As shown, the inside of the flipping cylinder 2 is provided with a partition 21 in the horizontal direction. The partition 21 is provided with four first placement holes 22 for placing sample bottles in the horizontal direction. Each first placement hole 22 is provided with a clamping mechanism for clamping the sample bottle.

[0038] The clamping mechanism includes four sets of two pneumatic rods 24 respectively disposed on the upper and lower sides of each first placement hole 22, and arc-shaped clamping pieces 25 respectively disposed on the two pneumatic rods 24 for clamping the sample bottle; the partition plate 21 is provided with an air pump 26, which adopts existing technology products, and the air pump 26 is connected to each pneumatic rod 24 through a pipe.

[0039] The housing 1 is equipped with a tilting motor 11 for driving the tilting cylinder 2 to rotate. The tilting motor 11 is a product of existing technology, and its output shaft is fixedly connected to a shaft located at the left end of the tilting cylinder 2. Figure 2 As shown, an inclined plate 12 for receiving sample vials is provided on the inner wall of the housing 1, and an opening 13 communicating with the left side of the inclined plate 12 is provided on the housing 1.

[0040] The tilting cylinder 2 is equipped with a temperature sensor and an electric heating element, and the housing 1 is equipped with a PLC controller. The temperature sensor and the electric heating element are electrically connected to the PLC controller. The tilting motor 11 is electrically connected to the PLC controller through a relay. The temperature sensor, the electric heating element, the relay, and the PLC controller are all products using existing technology.

[0041] The adding mechanism 3 includes two lead screws 31 arranged horizontally above the flipping cylinder 2, a feeding tube 33 arranged vertically between the two lead screws 31 and adding sample bottles inside the flipping cylinder 2, and a movable plate 32 sleeved on the feeding tube 33 and threadedly connected to the two lead screws 31.

[0042] like Figure 5 As shown, the two lead screws 31 are respectively disposed on both sides of the tilting cylinder 2, and both ends of the lead screws 31 are rotatably connected to the side wall of the housing 1. The right end of the lead screw 31 is provided with a drive mechanism for driving its rotation, such as... Figure 6 , Figure 7 As shown, a rotating shaft 34 is vertically and rotatably mounted on the movable plate 32 located on the right side of the feed tube 33. A rotating disk 35 is fixedly mounted on each end of the rotating shaft 34. The left sides of both rotating disks 35 extend into the feed tube 33 to close the feed tube 33. Each rotating disk 35 has a notch for intermittently opening the feed tube 33 by rotating it. The notches of the two rotating disks 35 are staggered.

[0043] A rack 36 parallel to the front lead screw 31 is provided below it. The rack 36 is fixedly connected to the housing 1, and a gear 37 that meshes with the rack 36 is fixedly sleeved on the rotating shaft 34. Four first placement holes 22 are equally spaced, and the distance between adjacent first placement holes 22 is equal to the circumference of the gear 37.

[0044] Both ends of the lead screw 31 are rotatably connected to the side wall of the housing 1 via connecting plates 14, and the right end of the lead screw 31 passes through the connecting plate 14; the driving mechanism includes first pulleys 311 respectively fixedly sleeved on the right ends of the two lead screws 31, and a motor 38 fixedly mounted on the housing 1; a transverse plate is provided between the two connecting plates 14 at the right ends of the lead screw 31, and the motor 38 is mounted on the transverse plate. The output shaft of the motor 38 is provided with a second pulley 381 for connecting to the two first pulleys 311 via a transmission belt. The motor 38 adopts existing technology products and is electrically connected to the PLC controller via a relay; a hopper 39 is provided above the feeding pipe 33.

[0045] The working principle of the above-mentioned oscillator is as follows: In the initial state, the upper rotating disk 35 closes the feeding pipe 33, and the notch of the lower rotating disk 35 is aligned with the feeding pipe 33.

[0046] When adding sample bottles, motor 38 drives two lead screws 31 to rotate through second pulley 381 and first pulley 311, causing movable plate 32 to move to the right. Since gear 37 meshes with rack 36, gear 37 will drive rotating shaft 34 to rotate as it moves with movable plate 32 until the feed tube 33 moves directly above the second placement hole 23. Rotating shaft 34 also drives two rotating disks 35 to rotate one revolution.

[0047] During the rotation of the shaft 34, the upper rotating disk 35 rotates until the notch aligns with the feed tube 33. At this time, the lower rotating disk 35 closes the feed tube 33, and the sample bottle in the feed tube 33 falls between the two rotating disks 35. As the shaft 34 completes one rotation, the notch of the lower rotating disk 35 aligns with the feed tube 33, and the sample bottle falls into the second placement hole 23.

[0048] As the movable plate 32 moves, sample vials are added sequentially into the four second placement holes 23. Then, the air pump 26 is started to inflate each air pressure rod 24 until the arc-shaped clamp 25 holds the sample vial. Then, the flipping motor 11 is started, which drives the flipping cylinder 2 to rotate and vibrate the sample in the sample vial. After the vibration is completed, the flipping motor 11 drives the flipping cylinder 2 to rotate 180 degrees, causing the air pump 26 to discharge the gas in each air pressure rod 24. At this time, the sample vial will fall onto the inclined plate 12 under the action of gravity and be discharged through the opening 13.
