Description

Technical Field

[0001] This utility model relates to the technical field of fully automatic laboratory glassware washing machines, and in particular to a lifting basket frame for laboratory glassware washing machines. Background Technology

[0002] In laboratories, fully automatic glassware is typically used for cleaning experimental equipment. To facilitate the placement of glassware, many existing fully automatic glassware washers employ pull-out racks that can slide in and out of the machine's interior. For some deep-cavity glassware, fully automatic washers usually have spray nozzles that directly spray water into the inner wall of the glassware to achieve the desired cleaning effect. However, in existing fully automatic washers, the position of the spray nozzle relative to the glassware is fixed during the cleaning process, which cannot guarantee that all parts of the inner wall receive the same water flow intensity, resulting in excessively long cleaning times.

[0003] Utility model patent CN202320199408.0 discloses a washing machine for test tubes. A spray pipe rinses the inner wall of the test tubes with liquid through spray nozzles. A mesh frame for holding the test tubes can move up and down in conjunction with an electric telescopic rod, allowing for more thorough rinsing of deep-cavity containers like test tubes. However, this washing machine cannot remove the mesh frame from the washing chamber, making it unsuitable for existing side-opening washing machines. Furthermore, partial damage to the mesh frame presents repair difficulties. Therefore, to improve the cleaning efficiency of existing side-opening washing machines for deep-cavity containers, a liftable basket compatible with existing side-opening washing machines is needed, allowing for reciprocating relative movement between the container and the spray pipe during the washing process. Utility Model Content

[0004] To address the shortcomings of traditional cleaning machines, such as fixed nozzle and vessel position leading to poor cleaning effect, and the inability to remove the mesh frame of retractable cleaning machines, making them unsuitable for side-opening cleaning machines and causing maintenance difficulties, this utility model provides a lifting basket frame for laboratory glassware cleaning machines that can be adapted to existing side-opening cleaning agent mesh baskets, thereby improving the cleaning effect.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A lifting basket for a laboratory glassware washing machine includes a screw, a lead screw nut, a transmission assembly, and a lifting frame. Two screws are symmetrically arranged, each with a guide rail fixing block at both ends. The screw rotates between the guide rail fixing blocks, with its top extending beyond the blocks. The screw body cooperates with the lead screw nut to form a lead screw transmission pair. The transmission assembly is located above the guide rail fixing block at the upper end of the screw and connected to the top of the screw. An F-shaped buckle is fixedly connected to the side of the lead screw nut. The lifting frame is a stainless steel wire mesh frame. Several sleeves that mate with the original water spray pipe of the washing machine are evenly arranged inside the mesh frame. Z-shaped buckles are fixedly installed on the middle of both sides, with the Z-shaped buckles slidingly engaging with the F-shaped buckles. The inner diameter of the sleeve is larger than the outer diameter of the water spray pipe.

[0006] Installation and usage methods of this utility model: During installation, first, vertically fix the two screws symmetrically to the two side walls of the inner cavity of the cleaning machine via the guide rail fixing blocks at both ends, ensuring that the top of the screws protrudes through the side wall of the cleaning machine. Then, install the transmission assembly on the outside of the cleaning machine and reliably connect it to the top of the two screws to achieve power transmission. Next, remove the original cleaning basket of the cleaning machine and slide the lifting frame into the cleaning basket from top to bottom, ensuring that each sleeve on the lifting frame can accurately fit into the original water spray pipe of the cleaning machine, and that the entire frame can move up and down smoothly without movement interference. Then, slide and engage the Z-shaped buckles on both sides with the F-shaped buckles fixed on the screw nut. During cleaning, invert the deep cavity container onto the sleeve. Here, a test tube is used for demonstration. The test tube is inverted onto the sleeve, with its surface resting against the lifting frame for support. At this point, the inner cavity of the test tube encloses the water spray pipe. Then, the lifting frame containing the vessel is pushed into the inner cavity of the washing machine along with the original washing basket. The washing machine's cleaning program and transmission components are activated. The transmission components installed on the outside of the washing machine drive the screw to rotate, which in turn drives the lifting frame to reciprocate vertically through the lead screw nut. This creates a relative displacement between the vessel and the water spray pipe. Simultaneously, the water from the washing machine is distributed through the main water pipe into the branch water pipe, and then supplied to each water spray pipe for cleaning. This allows the water flow to more thoroughly rinse the inner wall of the vessel. After cleaning, the washing machine is turned off. Then, the transmission components are turned off, and the entire washing basket can be pulled out to remove the test tube.

[0007] Furthermore, the transmission assembly includes a motor, a motor mounting beam, transmission gears, and a transmission belt. One side of the motor mounting beam is fixedly connected to the top surface of the guide rail mounting block, with a through hole in the middle allowing the screw to pass through. The bottom of the other side is fixedly connected to the motor, and the motor's transmission shaft extends upwards through the motor mounting beam. Transmission gears are fixedly installed on the top of the transmission shaft and the screw, respectively, and the two transmission gears are connected via a transmission connection to form a closed transmission circuit. When the cleaning machine starts the cleaning program, the motor is started, and the motor transmission shaft drives the transmission gears to rotate. Power is synchronously transmitted via the transmission belt to the transmission gear at the top of the screw, causing the screw to rotate synchronously. This precisely controls the lifting frame to smoothly perform reciprocating lifting motion. This transmission design is compact and provides stable power output, ensuring the uniformity and reliability of cleaning the inner wall of the vessel.

[0008] Furthermore, it also includes a microcontroller, which is electrically connected to the motors on both sides. The microcontroller can also communicate with the original main control system of the cleaning machine, receive operating commands issued by the cleaning machine, and uniformly control the lifting basket and the cleaning machine's spray system to work together.

[0009] Furthermore, a pad is fitted at the bottom of the sleeve, and the pad is connected to the mesh frame. During installation, the pad is fixed to the lifting frame. When test tubes or other deep-cavity vessels are inverted on the sleeve, the mouth of the vessel is supported by the pad, avoiding direct contact with the mesh frame. This reduces stress concentration, effectively prevents the edges of the vessel from breaking due to localized stress, and improves safety during use.

[0010] Furthermore, the bottom of the pad has connecting grooves on both sides that mate with the mesh frame, and the connecting grooves are engaged in the steel wires of the mesh frame. During installation, the pad and sleeve can be slid together on the mesh frame according to the specific layout of the original cleaning machine's spray pipes, easily adjusted to the optimal alignment position, and then locked in place. The positions of the pad and sleeve can be flexibly adjusted according to the spray pipe layout of different models of cleaning machines, greatly improving the adaptability and versatility of the lifting basket and solving the installation alignment problem caused by the fixed position of the spray pipes.

[0011] Furthermore, the upper end of the Z-type buckle should engage with the F-type buckle, and the contact surface should be flat. The flat contact between the Z-type and F-type buckles ensures smooth and uniform force transmission during the lifting process, effectively preventing the frame from tilting or jamming due to uneven force. At the same time, this buckle design facilitates the quick separation and engagement of the lifting frame and the transmission mechanism, making it convenient for the overall pushing, pulling, and placing of the basket rack.

[0012] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. This utility model, through the design of a liftable basket, enables the utensils to reciprocate relative to the water spray pipe of the washing machine during the washing process, which solves the problem of uneven cleaning of deep-cavity utensils caused by the fixed spray pipe in side-opening washing machines. At the same time, the mesh frame can be pushed and pulled as a whole with the original mesh basket, making it compatible with existing equipment and easy to maintain.

[0013] 2. This utility model ensures smooth and synchronous lifting through gear and chain transmission, flexibly adapts to different nozzle layouts with the help of sliding buckle fixed pads, and achieves reliable force transmission and quick assembly and disassembly through the planar contact of Z-type buckles and F-type buckles, which together improve the uniformity of cleaning, equipment versatility, safety of use and convenience of maintenance.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Example 1: A lifting basket for a laboratory glassware washing machine includes a screw 5, a lead screw nut 7, a transmission assembly, and a lifting frame. There are two screws 5 arranged symmetrically. Each screw 5 has a guide rail fixing block 8 at both ends. The screw 5 is rotatably positioned in the middle of the guide rail fixing block 8, with its top extending out of the guide rail fixing block 8. The screw body 6 cooperates with the lead screw nut 7 to form a lead screw transmission pair. The transmission assembly is located above the guide rail fixing block 8 at the upper end of the screw 5 and is connected to the top of the screw 5. The lead screw nut 7 has an F-shaped buckle 9 fixedly connected to its side. The lifting frame is a stainless steel wire mesh frame 15. The mesh frame 15 has several sleeves 12 evenly arranged inside, which cooperate with the original water spray pipe 11 of the washing machine. Z-shaped buckles 10 are fixedly installed on the middle of both sides, where the Z-shaped buckles 10 slide and engage with the F-shaped buckles 9. The inner diameter of the sleeve 12 is larger than the outer diameter of the water spray pipe 11.

[0020] During installation, first, vertically fix the two screws 5 symmetrically to the two side walls of the inner cavity of the cleaning machine via the guide rail fixing blocks 8 at both ends, ensuring that the top of the screws 5 protrudes through the side wall of the cleaning machine. Then, install the transmission assembly on the outside of the cleaning machine and reliably connect it to the top of the two screws 5 to achieve power transmission. Next, remove the original cleaning basket 14 of the cleaning machine and insert the lifting frame 15 into the cleaning basket 14 from top to bottom, ensuring that each sleeve 12 on the lifting frame 15 can accurately fit into the original water spray pipe 11 of the cleaning machine, and that the entire frame can move up and down smoothly without movement interference. Then, slide and engage the Z-shaped buckles 10 on both sides with the F-shaped buckles 9 fixed on the screw nut 7. During cleaning, invert the deep cavity container onto the sleeve 12. Here, a test tube is used for demonstration. The tube is inverted onto the sleeve 12, with its surface resting against the lifting frame 15 for support. At this time, the inner cavity of the test tube is wrapped around the water spray pipe 11. Then, the lifting frame 15 containing the container is pushed into the inner cavity of the cleaning machine along with the cleaning basket 14. The cleaning program and transmission components of the cleaning machine are started. The transmission components installed on the outside of the cleaning machine drive the screw 5 to rotate, which drives the lifting frame 15 to reciprocate in the vertical direction through the lead screw nut 7, causing relative displacement between the container and the water spray pipe 11. At the same time, the water from the cleaning machine is decomposed into the branch water pipe 17 through the main water pipe 16, and then supplied to each water spray pipe 11 for water spraying and cleaning, so that the water flow can more thoroughly rinse the inner wall of the container. After cleaning, the cleaning machine is turned off, and then the transmission components are turned off. The entire cleaning basket 14 can be pulled out to remove the test tube.

[0021] Example 2: Unlike Example 1, the transmission assembly includes a motor 1, a motor mounting beam 2, a transmission belt 3, and transmission gears 4. One side of the motor mounting beam 2 is fixedly connected to the top surface of the guide rail mounting block 8, with a through hole in the middle allowing the screw 5 to pass through. The bottom of the other side is fixedly connected to the motor 1, and the transmission shaft of the motor 1 extends upwards through the motor mounting beam 2. Transmission gears 4 are fixedly installed on the top of the transmission shaft and the screw 5, respectively, and the two transmission gears 4 are connected by the transmission belt 3 to form a closed transmission circuit. When the cleaning machine starts the cleaning program, the motor 1 is started, and the transmission shaft of the motor 1 drives the transmission gears 4 to rotate. The power is synchronously transmitted to the transmission gears 4 at the top of the screw 5 via the transmission belt 3, causing the screw 5 to rotate synchronously. This precisely controls the lifting frame 15 to smoothly perform reciprocating lifting motion. This transmission design is compact and provides stable power output, ensuring the uniformity and reliability of cleaning the inner wall of the vessel.

[0022] A pad 13 is also fitted at the bottom of the sleeve 12, and the pad 13 is connected to the mesh frame 15. During installation, the pad 13 is fixed on the lifting frame 15. When test tubes or other deep-cavity vessels are inverted on the sleeve 12, the mouth of the vessel is supported by the pad 13, avoiding direct contact with the mesh frame 15, thereby reducing stress concentration, effectively preventing the edge of the vessel from breaking due to local stress, and improving the safety of use.

[0023] The upper end of the Z-type buckle 10 should be inserted into the F-type buckle 9, and the contact surface should be flat. The flat contact between the Z-type buckle 10 and the F-type buckle 9 ensures the smooth and uniform force transmission during the lifting process, effectively preventing the frame from tilting or jamming due to uneven force. At the same time, this buckle design facilitates the quick separation and connection between the lifting frame 15 and the transmission mechanism, making it convenient for the overall pushing, pulling and placing of the basket frame.

[0024] Example 3: Unlike Example 2, it also includes a microcontroller, which is electrically connected to the motors 1 on both sides. The microcontroller can also communicate with the original cleaning machine's main control system, receive operating commands from the cleaning machine, and uniformly control the lifting basket and the cleaning machine's spray system to work together.

[0025] The bottom of the pad 13 has connecting grooves on both sides that mate with the mesh frame 15. The connecting grooves are inserted into the steel wires of the mesh frame 15. During installation, the pad 13 and sleeve 12 can be slid together on the mesh frame 15 according to the specific layout of the original cleaning machine's spray pipe 11. After easily adjusting to the optimal alignment position, they can be locked in place. The positions of the pad 13 and sleeve 12 can be flexibly adjusted according to the spray pipe layout of different models of cleaning machines, which greatly improves the adaptability and versatility of the lifting basket and solves the installation alignment problem caused by the fixed position of the spray pipe.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
