Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning the inner liner of a sample can. Specifically, the present invention relates to a cleaning device for the inner liner of a sample can and a method for using the same. Background Art

[0002] In many fields such as scientific research, industrial production, and quality inspection, sample cans are widely used to store various samples. Due to the diversity and particularity of samples, the cleaning requirements for the inner liner of the sample can are extremely high. Once impurities or contaminants remain in the inner liner, it may not only interfere with the subsequent detection results of the sample, but also cause chemical reactions in the sample, affecting its quality and performance. Currently, in the cleaning operation of the inner liner of the sample can, many drawbacks have emerged in the traditional manual operation process.

[0003] In the process of separating and assembling the bottle cap and the inner liner, it mainly relies on manual operation to unscrew and screw on the bottle cap. This process not only consumes a large amount of manpower, but also has a high labor intensity and extremely low operation efficiency. Long-term repetitive labor is likely to cause fatigue among workers, thereby increasing the probability of operation errors. For example, the bottle cap may not be screwed tightly, resulting in sample leakage, or it may be screwed too tightly, causing damage to the inner liner or the bottle cap. After the sample can is used, the inner liner after pouring out the material needs to be cleaned in a timely manner. The existing manual cleaning method usually involves an operator holding the inner liner and rinsing it in a sink or cleaning equipment. Due to the randomness of manual operation, it is difficult to ensure the consistency and comprehensiveness of the cleaning process, and it is easy to have cleaning dead corners, resulting in incomplete cleaning of the inner liner. At the same time, the efficiency of manual cleaning and drying is relatively low, making it difficult to meet the requirements of large-scale and high-efficiency production operations.

[0040] As Figures 1 to 12As shown in the figure, a cleaning device for the inner liner of a sample can includes a working chamber 1. Inside the working chamber 1, a first support plate 101 and a first support base 102 are provided. An inner liner separation mechanism 2 and an inner liner cleaning structure 3 are arranged on the first support plate 101. A transportation mechanism 4 is arranged at the top of the working chamber 1. A rotary clamping assembly 5 is arranged on the transportation mechanism 4. A flipping mechanism 6 is arranged on the first support base 102. The working chamber 1 provides an installation and working space for other structures, integrating all components in a relatively enclosed space, which is conducive to centralized control and management of the cleaning process and at the same time prevents water vapor and impurities during the cleaning process from spreading to the surrounding environment. The first support plate 101 and the first support base 102 are fixed inside the working chamber 1 by welding. The first support plate 101 provides a setting position for the inner liner separation mechanism 2 and the inner liner cleaning structure 3. The first support base 102 is used to install the flipping mechanism. The inner liner is separated from the bottle cap through the inner liner separation mechanism 2 and the rotary clamping assembly 5. Then the inner liner is transported to the inner liner cleaning structure 3 for cleaning through the transportation mechanism 4. The bottle cap is transported to the bottle cap cleaning assembly 7 through the transportation mechanism 4 for cleaning the bottle cap. The cleaned bottle cap and inner liner are then transported to the inner liner separation mechanism 2 through the transportation mechanism 4. The bottle cap is screwed onto the inner liner through the rotary clamping assembly 5. The inner liner is placed back into the bottle body. The cleaned inner liner, bottle cap and bottle body are taken out by a manipulator.

[0041] The inner liner cleaning structure 3 includes a first connecting column 301. A first cleaning cavity 302 is arranged inside the first connecting column 301.

The second cleaning pipeline 306 is communicated with a second cleaning spray head 307. The second cleaning spray head 307 faces the inner liner bottle mouth. A first drain pipe 308 is arranged at the bottom of the first cleaning cavity 302.

[0042] On both sides of the first connecting column 301, there are fixed plates. The first connecting column 301 is fixed by bolt - connecting the fixed plates to the first support plate 101. The first cleaning pipeline 304 and the second cleaning pipeline 306 are connected to the first connecting column 301 by welding to ensure a tight connection and prevent the leakage of cleaning liquid. The first hole 303 allows the inner tank to be sleeved on the first cleaning nozzle 305 through the first hole 303. The first cleaning nozzle 305 is installed in the first cleaning cavity. The first cleaning nozzle 305 is communicated with the first cleaning pipeline 304 and is fixed by threaded connection to ensure that the first cleaning nozzle 305 can stably spray out water vapor to clean the inside of the inner tank. The second cleaning nozzles 307 are symmetrically arranged. The second cleaning nozzles 307 are thread - connected to the second cleaning pipeline 306 and are facing the mouth of the inner tank. The second cleaning nozzles 307 spray out water vapor to clean the mouth of the inner tank. A flow - guiding plate is also arranged in the first cleaning cavity 302, and the waste liquid after cleaning flows to the first drain pipe 308 through the flow - guiding plate and is discharged.

[0043] The transportation mechanism 4 includes a horizontal transportation component 41 and a vertical transportation component 42. The horizontal transportation component 41 includes a second fixed plate 411. The second fixed plate 411 is connected to the working bin 1. A first motor 412 is arranged on the second fixed plate 411. A first pulley 413 is arranged at one end of the second fixed plate 411. A first lead screw 414 is arranged inside the second fixed plate 411. The first lead screw 414 is connected to the first pulley 413. The first motor 412 and the first pulley 413 are connected by a belt. The first lead screw 414 is thread - connected to a first slider 415. The first slider 415 is connected to a first sliding plate 416. The vertical transportation component 42 is arranged on the first sliding plate 416. The vertical transportation component 42 includes a third fixed plate 421. The third fixed plate 421 is connected to the first sliding plate 416. A second motor 422 is arranged on the third fixed plate 421. A second lead screw 423 is arranged inside the third fixed plate 421. One end of the second lead screw 423 is connected to a second pulley 424. The second motor 422 and the second pulley 424 are connected by a belt. The second lead screw 423 is thread - connected to a second slider 425. The second slider 425 is connected to a second sliding plate 426. The rotary clamping component 5 is connected to the second sliding plate 426.

[0044] The second fixed plate 411 in the horizontal transportation component 41 is bolted to the working bin 1. The first motor 412 is fixed on the second fixed plate 411. A transmission wheel is installed on the rotating shaft of the first motor 412 and the first pulley 413. The transmission wheel and the first pulley 413 are connected by a belt. The first lead screw 414 is connected to the first pulley 413. The first motor 412 can drive the belt, thereby driving the first pulley 413 and the first lead screw 414 to rotate. Since the first lead screw 414 is threadedly connected to the first slider 415, the first slider 415 moves horizontally in a straight line along the first lead screw 414 under the action of the thread, thereby driving the first slide plate 416 connected to the first slider 415 and the vertical transportation component 42 installed on the first slide plate 416 to move horizontally.

[0045] The third fixed plate 421 of the vertical transportation component 42 is bolted to the first slide plate 416. The second motor 422 is fixed on the third fixed plate 421. A transmission wheel is connected to the second motor 422 and the second pulley 424. The second pulley 424 and the transmission wheel are connected by a belt. The second lead screw 423 is connected to the second pulley 424. The second lead screw 423 is threadedly connected to the second slider 425. The second slider 425 is bolted to the second slide plate 426.

[0046] When in use, the second motor 422 is started. The second motor 422 drives the second pulley 424 to rotate. Through belt transmission, the second lead screw 423 rotates. The second slider 425 moves vertically in a straight line along the second lead screw 423 under the action of the thread, and then drives the second slide plate 426 connected to the second slider 425 and the rotary clamping component 5 installed on the second slide plate 426 to move vertically. Through the coordinated cooperation of the vertical transportation component 42 and the horizontal transportation component 41, the movement of the rotary clamping component 5 in the horizontal and vertical directions can be completed.

[0047] The rotary clamping component 5 includes a third motor 501 and a fourth motor 502. The fourth motor 502 is a double-shaft motor. The first clamping plates 503 are connected to the two side rotating shafts of the fourth motor 502. The third motor 501 is fixedly connected to the second slide plate 426. The rotating shaft of the third motor 501 is connected to the first movable plate 504. The first movable plate 504 is fixedly connected to the fourth motor 502. The rotary clamping component 5 realizes the clamping and rotation operations of the bottle cap and the inner liner, and can accurately unscrew and screw on the bottle cap. When screwing on the bottle cap, the tightness of the bottle cap can be ensured to be consistent, and it will not damage the inner liner due to being too tight or cause the liquid in the bottle to leak due to being too loose. A laser sensor is also provided on the first clamping plate 503. The laser sensor is connected to the PLC controller. When screwing on the bottle cap, the laser sensor compares the position when the bottle cap is tightened with the position of the bottle cap to judge whether the bottle cap is tightened in place. The signal is transmitted to the PLC controller, and the PLC controller controls the rotary clamping component 5 to make adjustments according to the signal.

[0048] During the process of transporting the inner container, the inner container is stably clamped to ensure the accuracy and stability of the operation process, and to prevent components from falling or being damaged during the operation. The two sides of the rotating shafts of the fourth motor 502 are connected with the first clamping plates 503. The first clamping plates 503 are driven by the rotation of the fourth motor 502 to clamp the inner container or the bottle cap. After clamping the inner container or the bottle cap, the fourth motor 502 stops and remains stable. The rotating shaft of the third motor 501 is connected with the first movable plate 504. When it is necessary to unscrew or screw on the bottle cap, the fourth motor 502 and the first clamping plates 503 are driven to rotate by the rotation of the third motor 501, so as to unscrew or screw on the bottle cap.

[0049] The inner container separation mechanism 2 includes a first fixing plate 201. The first fixing plate 201 is connected with the first support plate 101. At both ends of the first fixing plate 201, there are first cylinders 202. The first cylinders 202 are connected with first clamping blocks 203.

The body of the sample can is arranged in the first groove 208. In the working chamber 1, there is a third cylinder 209. The piston rod of the third cylinder 209 abuts against the inner container. The first fixing plate 201 is bolted to the first support plate 101. The first cylinders 202 are fixed at both ends of the first fixing plate 201, and their piston rods are connected with the first clamping blocks 203, enabling the first cylinders 202 to accurately push the first clamping blocks 203 to fix the bottle body. The second support seat 21 includes a support rod. A flat plate is arranged on the support rod. The other end of the support rod is connected with a bottom plate. By fixing the bottom plate on the first support plate 101 to fix the flat plate, the second cylinder 205 is fixed on the flat plate. The piston rod of the second cylinder 205 pushes the second clamping block 206 to move and clamp the inner container. The first groove 208 is used for placing the bottle body. The third cylinder 209 is used to push out the inner container. After the body of the sample can is placed in the first groove, the first cylinder 202 is started. The first cylinder 202 pushes the first clamping block 203. Since the first clamping block 203 is provided with the first arc surface 204 matching the body of the sample can, the body of the sample can can be tightly clamped and fixed in the first groove 208.

[0050] Then, the third cylinder 209 is started. The piston rod of the third cylinder 209 applies a thrust to the inner container and pushes the inner container out of the body of the sample can.

[0051] Then, start the second cylinder 205. The second cylinder 205 pushes the second clamping block 206. The second arc surface 207 on the second clamping block 206 matches the inner container, thereby clamping the inner container, completing the separation of the inner container from the sample jar body and the preliminary clamping of the inner container, so as to perform the capping operation on the inner container subsequently. Through the horizontal transportation component 41 and the vertical transportation component 42, the first clamping plate 503 is sent to both sides of the bottle cap on the inner container. Start the fourth motor 502 to control the first clamping plate 503 to clamp the bottle cap, and control the third motor 501 to drive the rotation of the first movable plate 504 and the first clamping plate 503 to unscrew the bottle cap;

[0052] Start the horizontal transportation component 41 and the vertical transportation component 42.
