Description

Technical Field

[0001] The invention belongs to the technical field of blood preparation auxiliary equipment, and in particular relates to a mechanism for effectively removing water drops and water mist on the surface of a pipeline during high-frequency heat sealing of a heat sealer. Background Art

[0002] Cryoprecipitation is the abbreviation of cold precipitated coagulation factor. It uses a specific method to melt fresh frozen plasma (FFP) at 1℃~6℃ during the storage period, separate most of the plasma, and quickly freeze the remaining cold-resistant substances into solid blood components within 1 hour. There are two commonly used preparation methods: centrifugation and siphoning. Fresh frozen plasma (FFP) needs to be melted in a constant temperature water bath melting box at 1℃~6℃. After the preparation of separated plasma is completed, the transfer tube of the linked bag needs to be heat-sealed to obtain cold precipitated coagulation factor and frozen plasma.

[0003] In the daily preparation process, after the plasma bag is separated in the water bath, the entire exterior is wet, and the staff needs to wipe the pipeline with a towel or gloves to reduce the residual water droplets. However, with the continuous use of the tools, the transfer and accumulation of liquids will gradually reduce the effective effect of wiping, and the residual water mist on the outer wall of the subsequent pipeline will gradually increase, which will have an adverse effect on the thermal synthesis molding of the subsequent heat sealing process.

[0004] The patent with the announcement number: CN115892631A discloses an extrusion heat-sealing device. It includes: a blood bag frame, which is used to accommodate a plurality of blood bags for component blood preparation; an extrusion mechanism, which includes two groups arranged on opposite sides of the blood bag frame, which are used to provide a Y-direction extrusion function for the blood bags in the blood bag frame; and a heat-sealing mechanism, which includes a movable heat-sealing end, a Z driving mechanism for driving the movable heat-sealing end to reciprocate along the Z direction, and a fixed heat-sealing end arranged on the side of the blood bag frame, and the movable heat-sealing end cooperates with the fixed heat-sealing end to provide an extrusion plugging and heat-sealing function for the hose on the blood bag.

[0005] In the production and preparation process of the prior art, there are at least the following problems:

[0006] In the daily preparation process of extrusion heat sealing, when there is water mist remaining on the pipeline, the distance between the hot electrode and the cold electrode is reduced, and the liquid on the surface of the pipeline can easily cause a short circuit between the two electrodes, resulting in an irregular heat-synthesized molding surface or even failure to heat seal. Summary of the invention

[0007] The present invention provides a mechanism for effectively removing water drops and water mist on the surface of a pipe during high-frequency heat sealing of a heat sealing machine, and is used to solve the technical problem in the prior art that when water mist remains on the pipe, the distance between the hot electrode and the cold electrode is reduced, and water, as a conductive medium, is prone to cause a short circuit between the two electrodes, resulting in an irregular heat-synthesized molding surface or even failure to heat seal.

[0008] In order to achieve the above object, the present invention is implemented by the following technical solutions:

[0009] A mechanism for effectively removing water droplets and water mist on the surface of a pipe during high-frequency heat sealing of a heat sealing machine, comprising: a mounting base, an electrode bracket, a photoelectric detection switch, two air nozzles, and an actuator. The mounting base is provided with a control unit; the electrode bracket is mounted on the mounting base, and the electrode bracket has a mounting channel; the photoelectric detection switch is mounted on the inner wall of the mounting channel, detects the installation position of the pipe, and transmits the detection position to the control unit in the mounting base; two air nozzles are mounted on the electrode bracket, and are connected to the control unit in communication; the actuator is mounted on the electrode bracket and passes through the mounting base, and the actuator performs heat sealing on the pipe after the surface water mist is removed, and the execution content and duration are set differently according to different processes, and the air nozzle is used to clean the actuator in the mounting channel.

[0010] Furthermore, the air nozzle comprises: a hot electrode air nozzle, a cold electrode air nozzle, and two solenoid valves. The hot electrode air nozzle is arranged on one end of the electrode bracket away from the mounting base; the cold electrode air nozzle is arranged on the first end of the electrode bracket close to the mounting base; the two solenoid valves are correspondingly installed on the hot electrode air nozzle and the cold electrode air nozzle, and the solenoid valves are communicatively connected with the photoelectric detection switch through the control unit.

[0011] Furthermore, the actuator includes: a hot electrode and a cold electrode. A slide groove is provided on one side of the installation channel of the hot electrode, and the hot electrode is slidably installed in the slide groove; the cold electrode is fixedly installed on the other side of the installation channel, and the hot electrode abuts against the cold electrode to complete heat sealing.

[0012] Furthermore, before heat sealing, the water mist on the surface of the pipeline in the installation channel is removed by controlling the two air nozzles.

[0013] Furthermore, during the heat sealing process, the two air nozzles are selectively controlled to adjust the pipelines in the heat sealing process to a certain extent to dry and assist in heat sealing.

[0014] Furthermore, after multiple heat sealing operations, the idle hot electrode and the cold electrode are alternately blown and cleaned by respectively controlling the hot electrode air nozzle and the cold electrode air nozzle.

[0015] Furthermore, it further comprises: a gas circuit installation part. The gas circuit installation part is installed at the bottom of the electrode support, and the gas circuit installation part is connected to the hot electrode air nozzle and the cold electrode air nozzle.

[0025] Example:

[0026] Please refer to Figure 1 As shown, this embodiment provides a mechanism for effectively removing water droplets and water mist on the surface of the pipe during the high-frequency heat sealing process of the heat sealing machine, including: a mounting base 1, an electrode bracket 2, a photoelectric detection switch 7, two air nozzles, and an actuator. The mounting base 1 is provided with a control unit; the electrode bracket 2 is mounted on the mounting base 1, and the electrode bracket 2 has an installation channel; the photoelectric detection switch 7 is mounted on the inner wall of the installation channel, and detects the installation position of the pipe, and transmits the communication to the control unit in the mounting base 1; the two air nozzles are mounted on the electrode bracket 2, and are connected to the control unit; the actuator is mounted on the electrode bracket 2, and passes through the mounting base 1, and the actuator performs heat sealing on the pipe after the surface water mist is removed, and the execution content and duration are set differently according to different processes, and the air nozzle cleans the actuator.

[0027] In this embodiment, if Figure 1 As shown, the installation base 1 is an expansion component, which is used to be installed on the equipment body of the heat-sealing pipeline, and is used to timely heat-seal and cut off the transfer tube of the joint bag. The rear part of the installation base 1 is separately integrated with a control center and a drive servo electrode and other structures, and the heat-sealing process is controlled by driving the actuator. The photoelectric detection switch 7 is specifically a photoelectric sensor and a relatively installed switch, and the photoelectric sensor is installed on one side of the actuator and is located in the installation channel to detect the installation position of the pipeline. The air nozzles are respectively installed on both sides of the installation channel, and the pipeline and the actuator in the installation channel are demisted and cleaned by re-outputting compressed air, as well as assisting the heat-sealing process. The water mist on the outer wall of the joint bag pipeline is exposed to the air and has conductivity, and the water film attached to the surface will affect the regularity of the heat-sealing surface.

[0028] Further, in some implementations of this embodiment, Figure 1As shown, the air nozzle includes: a hot electrode air nozzle 4, a cold electrode air nozzle 6, and two solenoid valves. The hot electrode air nozzle 4 is arranged on the end of the electrode bracket 2 away from the mounting base 1; the cold electrode air nozzle 6 is arranged on the first end of the electrode bracket 2 close to the mounting base 1; the two solenoid valves are correspondingly installed on the hot electrode air nozzle 4 and the cold electrode air nozzle 6, and the solenoid valves are communicated with the photoelectric detection switch 7 through the control unit.

[0029] In this embodiment, if Figure 1 As shown, the two air nozzles are symmetrically installed on both sides of the installation channel, and solenoid valves are independently installed in the air nozzles to cooperate with the control center in the installation base 1 to independently control the solenoid valves of the two air nozzles.

[0030] Further, in some implementations of this embodiment, Figure 1 As shown, the actuator includes: a hot electrode 8 and a cold electrode 5. A slide groove is provided on one side of the installation channel of the hot electrode 8, and the hot electrode 8 is slidably installed in the slide groove; the cold electrode 5 is fixedly installed on the other side of the installation channel, and the hot electrode 8 abuts against the cold electrode 5, thereby completing heat sealing.

[0031] In this embodiment, if Figure 1 As shown, a high-frequency transmitter is arranged on the hot electrode 8, a melting area is formed between the hot electrode 8 and the cold electrode 5, a sliding seat is arranged on the inner wall of the installation channel, a sliding hole is opened on the inner wall of the installation channel, the sliding seat is slidably arranged in the sliding hole, and the driving mechanism on the rear side of the installation base seat 1 drives the sliding seat along the sliding hole through a screw slider mechanism or a push cylinder or an electromagnet, and the hot electrode 8 is installed on the sliding seat, thereby driving the hot electrode 8 to approach and move toward the cold electrode 5 and the cold electrode nozzle 6.

[0032] Further, in some implementations of this embodiment, Figure 1 As shown, before heat sealing, the water mist on the surface of the pipe in the installation channel is removed by controlling two air nozzles.

[0033] In this embodiment, if Figure 1 As shown, when the pipeline with residual water mist on the outer wall enters the heat sealing station, the photoelectric detection switch 7 detects that the pipeline is installed in place, the solenoid valve opens, and compressed air passes through the hot electrode nozzle 4 and the cold electrode nozzle 6 to form a local air flow channel at the front end of the channel, and the outside of the pipeline is subjected to an extremely short air bath to take away the residual water mist and form a dry pipeline surface.

[0034] Further, in some implementations of this embodiment, Figure 1 As shown, during the heat sealing process, the two air nozzles are selectively controlled to adjust the two air nozzles to dry and assist the heat sealing of the pipeline to a certain extent.

[0035] In this embodiment, if Figure 1As shown, the hot electrode 8 extends forward, high frequency is emitted, and the pipeline in the melting area is melted. At the same time, the hot electrode 8 continues to extend forward until it contacts the cold electrode 5, and the high frequency is turned off. The pipeline is cooled and formed. After the heat-sealed surface is formed, the hot electrode 8 retreats to the starting point, and the pipeline can be taken out. In the heat-sealing process, the air nozzles on both sides can be opened at the same time to blow compressed air to increase the water mist removal strength.

[0036] Further, in some implementations of this embodiment, Figure 1 As shown, after multiple heat sealing, the idle hot electrode 8 and cold electrode 5 are alternately blown and cleaned by controlling the hot electrode air nozzle 4 and the cold electrode air nozzle 6 respectively.

[0037] In this embodiment, if Figure 1 As shown, with the accumulation of heat sealing times, in order to avoid the continuous accumulation of extremely tiny water mist residues on the cold electrode 5 and the hot electrode 8, the system of the control center will start the water mist self-cleaning mode after executing a certain number of heat sealing times. That is, under the premise that there are no pipelines in the channel, the hot electrode nozzle 4 and the cold electrode nozzle 6 independently blow compressed air in the form of alternating intervals to clean the corresponding hot electrode 8 and the cold electrode 5.

[0038] Further, in some implementations of this embodiment, Figure 1 As shown, it also includes: a gas circuit installation part 3. The gas circuit installation part 3 is installed at the bottom of the electrode support 2, and the gas circuit installation part 3 is connected to the hot electrode air nozzle 4 and the cold electrode air nozzle 6.

[0039] In this embodiment, if Figure 1 As shown, the gas path mounting member 3 is fixed below the electrode support 2 to support and improve the stability and reliability of the operation of the cold electrode tuyere 6 and the hot electrode tuyere 4 .

[0040] A mechanism is used to effectively remove water droplets and water mist on the surface of the pipe during the high-frequency heat sealing process of the heat sealing machine. By setting the cold electrode air nozzle 6 and the hot electrode air nozzle 4, the blowing time and frequency of the cold electrode air nozzle 6 and the hot electrode air nozzle 4 are differentiated in different processes and different actions, thereby reducing the water mist on the surface of the pipe in the installation space and the wetting of the hot electrode 8 and the cold electrode 5 by the water mist, thereby improving the heat sealing efficiency of the hot electrode 8 and the cold electrode 5 and the reliability of the heat sealing cutoff of the pipe of the couplet bag.

[0041] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
