Description

Technical Field

[0002] In chemical experiments, test tubes are one of the most commonly used experimental containers and are widely used in experimental operations such as preparation of various solutions and observation of chemical reactions. In order to ensure the accuracy and reliability of the experimental results, test tubes must be thoroughly cleaned before and after use to remove residual chemicals and other contamination.

When the top plate moves up and down at a high position, the rotating seat drives the test tube to rotate to achieve the drying effect, making the entire test tube cleaning process more convenient, and the entire device is driven in a purely mechanized manner. On the one hand, the structure of the device is simple and the manufacturing cost is low, and the entire device can freely use the cleaning liquid without fear of short circuit, which makes the use environment requirements of the device lower and the operation more convenient.

[0017] A test tube cleaning device for chemical and chemical experiments of the present invention:

[0018] 1. The test tube cleaning device for chemical and chemical experiments, when cleaning is needed, the test tube is placed upside down on the test tube placement plate and located between two arc-shaped clamping plates, and then the servo motor is started to drive the positioning plate and the driving plate to rotate. When the driving plate drives the driving rod to rotate into the driving groove, the driving groove can drive the intermittent rotating plate to rotate. When the driving groove rotates 90°, the driving rod is separated from the current driving groove, and then the positioning plate contacts the arc surface of the intermittent rotating plate and restricts the intermittent rotating plate to prevent the intermittent rotating plate from continuing to rotate. Each time the driving rod enters the driving groove, the intermittent rotating plate can be rotated by degrees, the intermittent rotating plate drives the rotating rod and the pulley to rotate, the pulley drives the conveyor belt to move, so that the conveyor belt performs intermittent motion, and the purpose of automatic intermittent motion transportation can be achieved, which greatly improves the cleaning efficiency of the device.

[0019] 2. In the test tube cleaning device for chemical and chemical experiments, the conveyor belt drives the clamping mechanism to move through the bearing column when it moves. When the L-shaped guide rod is in the short straight groove on the positioning groove, the arc-shaped clamping plates on both sides of the test tube are far away from it. When the L-shaped guide rod moves from the short straight groove of the positioning groove to the long straight groove, the L-shaped guide rod pushes the U-shaped connecting plate to move toward the test tube, and the U-shaped connecting plate pushes the push-pull plate to move. Because the push-pull inclined groove guides the guide column, when the push-pull plate moves, the guide column drives the L-shaped sliding plate, the lifting guide rail and the lifting slide block to approach the test tube, so that the lifting guide rail can drive the arc-shaped clamping plate to clamp the test tube, thereby fixing the test tube, so that the test tube will not fall and be damaged during the cleaning process.

[0020] 3. The test tube cleaning device for chemical and chemical experiments has an arc-shaped clamping plate that continues to move after clamping the test tube, so that the test tube is separated from the test tube placement plate and then cleaned by a water gun. When the test tube moves one circle on the conveyor belt from the initial stage, the L-shaped guide rod is re-positioned in the short straight groove of the positioning groove, so that the clamping mechanism can release the clamping of the test tube, and the automatic intermittent movement of the conveying mechanism can give the staff enough time to take out the test tube and place another test tube, thereby improving the cleaning efficiency of the chemical test tube.

[0021] 4. The test tube cleaning device for chemical and chemical experiments, the moving plate drives the L-shaped carrier to move, the L-shaped carrier drives the lifting slide column to move through the convex slider and the annular slide, because the lifting plate guides the lifting slide column, so that the lifting slide column moves along the lifting groove, when the lifting slide column moves upward from the inclined groove of the lifting groove, the lifting slide column drives the positioning circular plate to rise through the annular slide, and the positioning circular plate drives the lifting extension rod and the sponge brush to rise, so that the sponge brush is inserted into the test tube, when the L-shaped lifting connecting rod moves from the straight groove to the reciprocating groove, the reciprocating groove causes the L-shaped lifting connecting rod to reciprocate, and the L-shaped lifting The connecting rod pulls the L-shaped extension rod and the lifting tube to perform reciprocating lifting and lowering, the L-shaped extension rod drives the lifting slider and the arc-shaped clamping plate to move, and the arc-shaped clamping plate drives the test tube to perform reciprocating lifting and lowering. When the sponge brush is inside the test tube, friction is generated between the surface of the sponge brush and the inside of the test tube, making the cleaning more thorough, eliminating the phenomenon of residual attachments, and improving the cleaning effect and cleanliness of the chemical test tube. When the sponge brush is separated from the test tube, the water in the test tube falls due to its gravity, and the inertia force generated by the reciprocating motion of the test tube driven by the arc-shaped clamping plate controls the water inside the test tube to dry, thereby improving the drying effect and drying speed of the test tube.

[0022] 5. In the test tube cleaning device for chemical and chemical experiments, when the L-shaped carrier drives the rotating rod to move, the gear on the rotating rod contacts the teeth, so that the gear drives the rotating rod and the lifting extension rod to rotate. During the rotation of the lifting extension rod, the sponge brush is driven to rotate inside the test tube, with fast cleaning speed and high work efficiency. When the sponge brush is not rotating inside the test tube, the centrifugal force generated by the rotation of the sponge brush causes the moisture inside the test tube to be dried, so that the test tube can be cleaned next time.

[0052] like Fig.15As shown, the sponge brush 504 used in the cleaning process needs to be dried in time after use, otherwise it is easy to breed bacteria or mold, affecting the subsequent use effect.

[0053] The working principle of a test tube cleaning device for chemical and chemical experiments: when in use, first add cleaning liquid into the cleaning tank 102, start the water pump 11, and the water pump 11 sucks the cleaning liquid in the cleaning tank 102 into the filter 13 through the water suction pipe 12 for filtration.

The filtered cleaning liquid is then discharged into the water spray gun 16 through the drain pipe 15. The water spray gun 16 is aimed at the test tube mouth for spraying. When cleaning is required, the test tube is placed upside down on the test tube placement plate 105 and located between the two arc-shaped clamping plates 307, and then the servo motor 201 is started to drive the positioning plate 202 and the driving plate 203 to rotate. When the driving plate 203 drives the driving rod When the drive groove 204 is rotated into the drive groove 206, the drive groove 206 can push the intermittent rotating plate 205 to rotate. When the drive groove 206 rotates 90°, the drive rod 204 is separated from the current drive groove 206, and then the positioning plate 202 contacts the arc surface of the intermittent rotating plate 205 and restricts the intermittent rotating plate 205 to prevent the intermittent rotating plate 205 from continuing to rotate. Each time the drive rod 204 enters the drive groove 206, the intermittent rotating plate 205 can be rotated 90°, and the intermittent rotating plate 205 drives the rotating rod 207 and the pulley 208 to rotate, and the pulley 208 drives the conveyor belt 209 to move, so that the conveyor belt 209 performs intermittent motion, and the purpose of automatic intermittent motion transportation can be achieved, which greatly improves the cleaning efficiency of the device.

[0054] When the conveyor belt 209 moves, the clamping mechanism 3 is driven to move through the bearing column 210. When the L-shaped guide rod 37 is in the short straight groove on the positioning groove 39, the arc-shaped clamping plates 307 on both sides of the test tube are far away from it. When the L-shaped guide rod 37 moves from the short straight groove of the positioning groove 39 to the long straight groove, the L-shaped guide rod 37 pushes the U-shaped connecting plate 36 to move in the direction of the test tube, and the U-shaped connecting plate 36 pushes the push-pull plate 33 to move. Because the push-pull inclined groove 34 guides the guide column 35, when the push-pull plate 33 moves, the guide column 35 drives the L-shaped sliding plate 304, the lifting guide rail 305 and the lifting slide block 306 to approach the test tube direction, so that the lifting guide rail 305 can drive the arc-shaped clamping plate 307 to clamp the test tube, so as to fix the test tube, so that the test tube will not fall and be damaged during the cleaning process.

[0055] After the arc-shaped clamping plate 307 clamps the test tube, it continues to move, so that the test tube is separated from the test tube placement plate 105 and then the water gun 16 cleans it. When the test tube moves one circle on the conveyor belt 209 from the initial stage, the L-shaped guide rod 37 is relocated in the short straight groove of the positioning groove 39, so that the clamping mechanism 3 can release the clamping of the test tube, and the automatic intermittent movement of the conveying mechanism 2 can allow the staff to have enough time to take out the test tube and place another test tube, thereby improving the cleaning efficiency of the chemical test tube;

[0056] The moving plate 302 drives the L-shaped carrier 501 to move, and the L-shaped carrier 501 drives the lifting slide 509 to move through the convex slider 507 and the annular slide 506. Because the lifting plate 51 guides the lifting slide 509, the lifting slide 509 moves along the lifting groove 52. When the lifting slide 509 moves upward from the inclined groove of the lifting groove 52, the lifting slide 509 drives the positioning circular plate 505 to rise through the annular slide 506. The positioning circular plate 505 drives the lifting extension rod 503 and the sponge brush 504 to rise, so that the sponge brush 504 is inserted into the test tube. When the L-shaped lifting connecting rod 403 moves from the straight groove 405 to the reciprocating groove 406, the reciprocating groove 406 enables the L-shaped lifting connecting rod 403 to Reciprocating motion, the L-shaped lifting connecting rod 403 pulls the L-shaped extension rod 401 and the lifting tube 402 to reciprocate and lift, the L-shaped extension rod 401 drives the lifting slider 306 and the arc-shaped clamping plate 307 to move, and the arc-shaped clamping plate 307 drives the test tube to reciprocate and lift. When the sponge brush 504 is inside the test tube, friction is generated between the surface of the sponge brush 504 and the inside of the test tube, and the cleaning is more thorough, eliminating the phenomenon of residual attachments, thereby improving the cleaning effect and cleaning cleanliness of the chemical test tube. When the sponge brush 504 is separated from the test tube, the water in the test tube falls by its gravity, and the inertial force generated by the reciprocating motion of the test tube driven by the arc-shaped clamping plate 307 controls the water inside the test tube to dry, thereby improving the drying effect and drying speed of the test tube;

[0057] When the L-shaped carrier 501 drives the rotating rod 502 to move, the gear 601 on the rotating rod 502 contacts the teeth 603, so that the gear 601 can drive the rotating rod 502 and the lifting extension rod 503 to rotate. During the rotation of the lifting extension rod 503, the sponge brush 504 is driven to rotate inside the test tube, so that the cleaning speed is fast and the work efficiency is high. When the sponge brush 504 is not rotating inside the test tube, the centrifugal force generated by the rotation of the sponge brush 504 is used to dry the moisture inside the test tube, so that the test tube can be cleaned next time.

[0058] It should be noted that the specific models and specifications of the servo motor 201, the water spray gun 16, the water pump 11, the filter 13 and the sponge brush 504 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0059] It should be noted that the principles of the servo motor 201, the water spray gun 16, the water pump 11 and the filter 13 are clear to those skilled in the art and will not be described in detail here.
