Description

Technical Field

[0001] The utility model belongs to the field of sample melting machines, and in particular relates to an automatic melting device for the sample melting machine. Background Art

[0002] The fusion sample machine is a device that uses the glass melting method to prepare glass flakes. It is a sample preparation instrument for AAS, ICP, and X-fluorescence analysis. It basically eliminates the mineral effect and the enhanced absorption effect of the matrix, and has high measurement precision and good accuracy.

[0003] When the melting machine melts the sample, the sample needs to be placed in a crucible. The melting machine heats the crucible and then melts the sample in the crucible. During the melting process, in order to ensure that the sample melts more evenly, the crucible needs to be shaken during the melting process. After the sample is melted, the sample in the crucible needs to be poured into a cooling dish to make a glass melt, and then experimental analysis can be carried out.

[0004] For example, our company's patent "A rotating and swinging melting and positioning device for samples for melting machines" has an application number of 202323653248.1. It can rotate and swing the sample during the melting process to make the sample melt more evenly. After the melting is completed, the crucible is clamped by a robot. The device currently has the following defects: 1. Only one sample can be melted at a time, which is very inefficient; 2. In order to facilitate the robot to clamp the crucible, the electromagnetic induction coil and the crucible in the equipment are directly exposed to the outside, and there is a safety hazard of burns to the operator during use; 3. The equipment needs to be used with a robot, and the overall area is large, which is not suitable for use in small laboratories. At the same time, the robot is relatively expensive and the cost of use is high. Once a failure occurs, the company that produces the equipment needs to send a special technician to repair it, which is troublesome and costly. Traditional melting machines usually use chain drive to shake the crucible, which has a relatively high failure rate and requires frequent maintenance.

[0005] In order to solve the above problems, the utility model provides an automatic melting device for a melting machine. Utility Model Content

[0017] This melting machine uses an automated melting device. When in use, the furnace cover is first opened, and the staff starts the cover-opening motor. The cover-opening motor drives the cover-opening shaft to rotate forward through the first turbine reducer, and the cover-opening shaft drives the furnace cover to lift up through the traction component. When the cover-opening sensor piece corresponds to the cover-opening sensor switch set at the bottom of the cover-opening sensor bracket, the furnace cover is in the open state, and the cover-opening sensor switch transmits the control signal to the cover-opening motor, and the cover-opening motor is closed. Then the lifting motor is started, and the lifting motor drives the screw to rotate forward. The screw drives the connecting plate to move upward through the nut fixing seat, and the connecting plate drives the slider to move upward. When the displacement sensing piece set on the connecting plate corresponds to the displacement sensing bracket, the When the displacement sensing piece provided on the connecting plate corresponds to the displacement sensing switch at the bottom of the displacement sensing bracket, the displacement sensing switch transmits the control signal to the lifting motor, and the lifting motor is turned off. At this time, the crucible rotating device and the crucible rack are also driven by the connecting plate to rise to the fixed position. The staff places the crucible on the crucible rack and starts the lifting motor again. The lifting motor drives the lead screw to rotate in the opposite direction. The lead screw drives the connecting plate downward through the nut fixing seat, and the connecting plate drives the slider downward. When the displacement sensing piece provided on the connecting plate corresponds to the displacement sensing switch at the bottom of the displacement sensing bracket, the displacement sensing switch transmits the control signal to the lifting motor, and the lifting motor is turned off. At this time, the crucible rotating device and the crucible rack are also driven by the connecting plate. It descends to a fixed position, and then the cover-opening motor is started. The cover-opening motor drives the cover-opening shaft to rotate in the opposite direction through the first turbine reducer, and the cover-opening shaft drives the furnace cover to close through the traction component. When the cover-opening sensor piece corresponds to the cover-opening sensor switch set in the middle of the cover-opening sensor bracket, the furnace cover is in a closed state, and the cover-opening sensor switch transmits a control signal to the cover-opening motor, and the cover-opening motor is turned off; after the sample melting begins, when the furnace chamber needs to be swung, the staff starts the swing motor, and the swing motor drives the swing component through the second turbine reducer, and the swing component drives the swing shaft, which in turn drives the furnace chamber to swing, and the first swinging sensor piece and the second swinging sensor piece swing with the swinging of the swing component When the first swinging sensing piece corresponds to the first swinging sensing switch, the first swinging sensing switch transmits a control signal to the swinging motor to make the swinging motor swing in the reverse direction. When the second swinging sensing piece corresponds to the second swinging sensing switch, the second swinging sensing switch transmits a control signal to the swinging motor to make the swinging motor swing in the forward direction. When the furnace does not need to swing, the staff turns off the swinging motor; when the crucible needs to be rotated, the staff starts the rotating motor, and the rotating motor drives the rotating shaft to rotate through the rotating coupling, and the rotating shaft drives the crucible bracket and the crucible rack to rotate. When the sample melting is completed, the staff turns off the rotating motor and repeats the above steps of placing the crucible to take out the crucible.

[0018] There are 2 to 8 crucible rotating devices, and each crucible rotating device is independently connected to the crucible rack. The staff can flexibly choose to rotate any one or more crucibles according to actual needs. At the same time, when the crucible rotating device fails, because each crucible rotating device is independently set, the other crucible rotating devices can still be used normally, avoiding the situation where the entire equipment cannot melt the sample normally due to a failure of the crucible rotating device. The structural design of the crucible rotating device itself is very simple, and the technical threshold for staff to repair it is very low. Enterprises that produce equipment do not need to send special technicians to repair it, which reduces production and use costs.

[0019] There is an angle of 10-40° between the first swinging sensing plate and the second swinging sensing plate. During the melting process of the sample, the automatic swing of the furnace can be achieved through the cooperation of the swinging device, the swinging assembly and the swinging sensing assembly, so that the sample can be mixed more evenly during the melting process, while improving the degree of automation of the equipment.

[0020] When the staff needs to place the crucible in the furnace or take the crucible out of the furnace, the lifting device and the rotating device are used to lift the crucible to a suitable position for taking it, making it convenient for the staff to use clamping tools to take the crucible. At the same time, because the heating process is all inside the furnace, the staff is prevented from being burned by the exposed electromagnetic induction coil and crucible, reducing the floor space and use cost of the melting machine itself.

[0021] During the sample melting process, the swing device drives the swing shaft through the swing assembly, and the swing shaft drives the furnace to swing. During the swinging process, the furnace also drives the lifting device and the crucible rotating device at the bottom of the furnace to swing. When the furnace swings, the crucible rotating device drives the crucible to rotate, so that the sample melt performs eddy current motion in the crucible, which can enable the sample to achieve the best uniformity and bubble removal effect in the shortest time, so as to obtain samples with good reproducibility, thereby improving work efficiency and detection accuracy.

[0022] The beneficial effects of the utility model are:

[0023] The utility model has a simple structure and is easy to use, reduces the failure rate and maintenance difficulty of the equipment, can melt multiple samples at the same time, improves the melting efficiency, reduces the cost and floor space of the equipment itself, and reduces safety hazards.

When the displacement sensor switch 142 at the lower part of the sensing bracket 141 corresponds, the displacement sensor switch 142 transmits the control signal to the lifting motor 1106, and the lifting motor 1106 is turned off. At this time, the crucible rotating device 12 and the crucible rack 13 are also driven by the connecting plate 1111 to drop to a fixed position, and then the cover opening motor 33 is started. The cover opening motor 33 drives the cover opening shaft 34 to rotate in the opposite direction through the first turbine reducer 32, and the cover opening shaft 34 drives the furnace cover 2 to close through the traction component 4. When the cover opening sensor sheet 53 corresponds to the cover opening sensor switch 52 set in the middle of the cover opening sensor bracket 51, the furnace cover 2 is in a closed state, and the cover opening sensor switch 52 transmits the control signal to the cover opening motor 33, and the cover opening motor 33 is turned off. After the sample melting begins, when it is necessary to swing the furnace chamber 1 When the swing motor 103 is turned on, the staff starts the swing motor 103, and the swing motor 103 drives the swing assembly 8 through the second turbine reducer 102, and the swing assembly 8 drives the swing shaft 6, and then drives the furnace 1 to swing. The first swing sensor piece 94 and the second swing sensor piece 95 swing along with the swing of the swing assembly 8. When the first swing sensor piece 94 corresponds to the first swing sensor switch 92, the first swing sensor switch 92 transmits a control signal to the swing motor 103 to make the swing motor 103 swing in the reverse direction. When the second swing sensor piece 95 corresponds to the second swing sensor switch 93, the second swing sensor switch 93 transmits a control signal to the swing motor 103 to make the swing motor 103 swing in the forward direction. When the furnace 1 does not need to swing, the staff turns off the swing motor 103.When the crucible needs to be rotated, the operator starts the rotary motor 125, which drives the rotary shaft 122 via the rotary coupling 124. The rotary shaft 122 then drives the crucible support 121 and the crucible rack 13 to rotate. When the sample is melted, the operator turns off the rotary motor 125 and repeats the above steps to remove the crucible. The present invention has a simple structure and is easy to use, which reduces the equipment's failure rate and maintenance difficulty. It can melt multiple samples simultaneously, improving melting efficiency. Compared to the prior art, which requires a robot to remove the crucible, the present invention reduces the cost and floor space of the equipment itself, and reduces safety hazards.
