[0024] Example 1: This utility model proposes a heat sealing machine.

[0025] In one embodiment of this utility model, a heat sealing machine includes a housing 1, a power supply, a control module 2, a display screen 3, and a heat sealing assembly 4. The power supply and control module 2 are disposed inside the housing 1. The control module 2 is communicatively connected to the display screen 3. The display screen 3 is disposed on the housing 1 and is used to display heat sealing status information. The heat sealing assembly 4 is disposed inside the housing 1 and has an end protruding outside the housing 1 for heat sealing of pipelines. A charging handle 5 is disposed at the bottom of the housing 1. The power supply is disposed inside the charging handle 5. A limit block 6 is disposed on the housing 1, and a limit groove for the limit block 6 to be inserted and engaged is provided on the charging handle 5. A charging interface of the power supply and a charging status indicator light are disposed on the outer wall of the charging handle 5.

[0026] Specifically, such as Figures 1 to 3As shown, in this heat sealing machine, a power supply is installed inside the housing 1. The power supply can be a rechargeable lithium-ion battery, and it can be electrically connected to the control module 2, heat sealing components 4, and other components through the power management module built into the housing 1, thereby providing independent power for the operation of the heat sealing machine. Compared with the existing tabletop or split-type heat sealing machines that rely on external power supplies, this heat sealing machine is free from the constraints of power lines, making it easy for staff to carry and move. In scenarios such as transferring patient fluid pipelines between different departments in hospitals, mobile operations between blood collection vehicles and laboratories, or alternating operations at multiple workstations in cell therapy workshops, staff do not need to frequently plug and unplug power or move the machine, significantly improving the flexibility and ease of operation, reducing space occupation, preventing the heat sealing machine from hindering normal work, and improving work efficiency.

[0027] Furthermore, in this heat sealing machine, a display screen 3 is provided on the housing 1, and the display screen 3 is communicatively connected to the control module 2. The display screen 3 can display real-time status information such as heat sealing temperature, number of heat sealing cycles, battery level, and heat sealing progress, making the entire heat sealing process transparent and controllable. This helps operators accurately grasp the operating status, thereby reducing the operational error rate and ensuring heat sealing quality. Understandably, since the protective cover 10 of the heat sealing component 4 is detachably installed at one end of the housing 1, the detachable installation method of the protective cover 10 and the housing 1 can be a threaded connection or a snap-fit ​​connection. This allows operators to quickly and easily remove the protective cover 10 from the housing 1 for cleaning and maintenance, reducing the frequency and cost of equipment maintenance. This is particularly suitable for fields with extremely high hygiene requirements, such as medical and biological products.

[0028] In addition, the charging handle 5 is located at the bottom of the housing 1, making it easy for staff to hold and operate the heat sealing machine. The power supply is located inside the charging handle 5, and the limiting block 6 and the limiting groove are connected in a plugging manner, which not only ensures a stable connection between the power supply and the housing 1, but also allows for quick connection or separation of the charging handle 5 and the housing 1. This avoids the constraints of external power lines and significantly improves the flexibility of the equipment in hospital departments, blood banks and other scenarios. At the same time, by setting a charging interface and status indicator light on the outer wall of the charging handle 5, staff can intuitively grasp information such as the charging progress of the power supply.

[0029] In one embodiment, the heat sealing assembly 4 includes a sleeve 7, a heating element 8, a driving assembly, and a pressure block 9. One end of the housing 1 is provided with a protective cover 10 for shielding the heating element 8. The sleeve 7 is detachably installed inside the housing 1. One end of the sleeve 7 is provided with a heating element 8 extending out of the housing 1, and the heating element 8 is located inside the protective cover 10. The protective cover 10 has a through hole. The driving assembly is disposed inside the sleeve 7 and is used to drive the pressure block 9 through the through hole to cooperate with the heating element 8 and heat seal the pipeline.

[0030] Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, in this heat sealing machine, the sleeve 7 is detachably installed inside the housing 1 via a threaded connection, facilitating disassembly and assembly and simplifying maintenance. Furthermore, since a heating element 8 extending outside the housing 1 is fixedly mounted at one end of the sleeve 7 and is located inside the protective cover 10, the protective cover 10 can shield the heating element 8, preventing accidental hand contact with the high-temperature heating element 8 during use and improving safety. Simultaneously, since the protective cover 10 has a through hole corresponding to the position of the heating element 8 for the pressure block 9 to pass through, and the drive component inside the sleeve 7 can be a miniature cylinder or an electric push rod, connecting the power output end of the drive component to the pressure block 9 allows the pressure block 9 to pass through the through hole under the action of the drive component to cooperate with the heating element 8 and perform heat sealing on the pipeline. The structural design is simple and reasonable. It should be noted that the heating element 8 and the pressure block 9 can respectively employ existing hot and cold electrodes.

[0031] In one embodiment, the drive assembly includes a drive member 11, a rotating cylinder 12, a connecting cylinder 13, and a rotating shaft 14. The drive member 11 is disposed inside the sleeve 7, and the power output end of the drive member 11 is detachably connected to the rotating cylinder 12. The connecting cylinder 13 and the rotating shaft 14 are both inserted inside the rotating cylinder 12, and the connecting cylinder 13 is threadedly connected to the rotating shaft 14 and the rotating cylinder 12. One end of the rotating shaft 14 extends out of the rotating cylinder 12 and is provided with a pressure block 9.

[0032] Specifically, such as Figure 5 As shown, the driving component 11 can be a micro stepper motor as in the prior art, and it is fixedly installed inside the sleeve 7. The power output end of the driving component 11 can be detachably connected to the rotating drum 12 through a threaded connection or other means. This not only facilitates the disassembly, repair, or replacement of the driving component 11, but also allows the rotating drum 12 to rotate relative to the sleeve 7 under the action of the driving component 11. At the same time, since the connecting cylinder 13 and the rotating shaft 14 are coaxially inserted inside the rotating drum 12, and the outer peripheral wall of the connecting cylinder 13 is connected to the inner peripheral wall of the rotating drum 12, the connecting cylinder 13 and the rotating shaft 14 are also connected to the rotating drum 12. The inner circumferential wall of 13 and the outer circumferential wall of the rotating shaft 14 are both threaded. When the rotating drum 12 rotates under the action of the driving component 11, the rotating drum 12 can drive the connecting drum 13 to rotate synchronously, thereby driving the rotating shaft 14 to rotate relative to the connecting drum 13, thereby driving the rotating shaft 14 to move along the axial direction of the rotating drum 12, so that the end of the rotating shaft 14 away from the connecting drum 13 extends out of the rotating drum 12 and drives the pressure block 9 to move towards the heating component 8, thereby completing the heat sealing operation of the pipeline. The structural design is ingenious and reasonable.

[0033] In one embodiment, a power supply interface 15 is provided on the top surface of the charging handle 5, and a pin 16 is provided on the control module 2 to engage with the power supply interface 15. Specifically, as shown... Figure 1 As shown, when it is necessary to remove the charging handle 5, the operator pushes the limiting block 6 away from the charging handle 5 to disengage it from the limiting slot, so that the charging handle 5 can be quickly removed. At this time, the pin 16 on the control module 2 can be directly separated from the power supply interface 15 on the charging handle 5, without the need for the operator to perform any other disassembly or assembly steps. It is simple and convenient to use.

[0034] In one embodiment, the housing 1 includes a bottom shell 17 and a top shell 18, which are detachably connected. A display screen 3 is provided on the top of the top shell 18. The bottom shell 17 has a mounting hole for the charging handle 5 to extend into. A positioning groove is provided on the wall of the mounting hole. The charging handle 5 has a positioning protrusion 19 that is inserted into the positioning groove.

[0035] Specifically, such as Figure 1 As shown, the bottom shell 17 and the top shell 18 are detachably connected by a snap-fit ​​and bolt reinforcement, which facilitates maintenance personnel to open the shell 1 to repair or replace internal heat-sealed components 4, etc., thus improving maintenance. The top panel of the top shell 18 is equipped with a display screen 3, which is positioned to match the eye angle of the operator when holding the device, improving the operator's observation convenience. Furthermore, when it is necessary to disassemble or assemble the charging handle 5, the operator can push it to initially position it through the insertion of the positioning groove and the positioning protrusion 19, which facilitates installation. At the same time, after the top of the charging handle 5 is installed in the mounting hole, the pin 16 is inserted into the power supply interface 15, thus satisfying the power supply to the control module 2. The structural design is simple and reasonable.

[0036] In one embodiment, an identification structure 20 is provided at the other end of the top shell 18. Specifically, as shown... Figure 1 and Figure 2 As shown, since the top shell 18 is provided with an identification structure 20 at the end away from the heat sealing component 4, the identification structure 20 can be laser-engraved to indicate the equipment specifications and safety precautions of the heat sealing machine of this utility model, so as to play a safety warning role for the staff.

[0037] In one embodiment, the charging handle 5 is provided with a button 21 for the control module 2; a protrusion 22 is formed on the bottom of the charging handle 5. Specifically, as shown... Figure 3As shown, the charging handle 5 has control buttons 21, such as a power button, a heat-sealing start button, and an emergency stop button, embedded near the top, which are connected to the control module 2. This improves the convenience of heat-sealing operations for operators, making it simple, convenient, and ergonomic. Furthermore, the protrusion 22 formed at the bottom of the charging handle 5 prevents slippage due to wet hands, improving grip stability and enhancing ergonomic comfort.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
