Description

Technical Field

[0001] This application relates to the field of pipeline heat sealing technology, and in particular to a heat sealing machine. Background Technology

[0002] Heat sealing machines are important equipment used in the medical field for sealing blood bag tubing. Their main function is to seal blood bag tubing by heating and pressurizing, ensuring the safety and sterility of blood during collection, storage and transfusion.

[0003] The current heat sealing machine includes a base, a first heat sealing electrode, and a second heat sealing electrode. The first heat sealing electrode is fixed to the base, and the second heat sealing electrode is slidably disposed on the base. The second heat sealing electrode can slide towards or away from the first heat sealing electrode. In use, the pipe to be sealed is placed between the two pipes. At this time, the second heat sealing electrode slides towards the first heat sealing electrode, and the first and second heat sealing electrodes clamp the pipe and perform heat sealing, thus achieving a seal on the pipe.

[0004] However, since pipes can be installed vertically or horizontally, the aforementioned heat sealing machine can only heat seal pipes in one orientation, resulting in limited applicability. Utility Model Content

[0005] The purpose of this application is to provide a heat sealing machine in which the installation angles of the first heat sealing electrode and the second heat sealing electrode can be adjusted, thereby adapting to horizontal and vertical pipes and having high applicability.

[0006] The heat sealing machine provided in this application adopts the following technical solution:

[0007] A heat sealing machine, comprising:

[0008] The main body of the heat sealing machine has a first installation station and a second installation station;

[0009] A first heat-sealing electrode block and a second heat-sealing electrode block are symmetrically arranged and detachably connected to the body of the heat-sealing machine. The second heat-sealing electrode block can move away from or towards the first heat-sealing electrode block.

[0010] When the first heat-sealed electrode block and the second heat-sealed electrode block are in the first installation position, the first heat-sealed electrode block and the second heat-sealed electrode block are in a horizontal state;

[0011] When the first heat-sealed electrode block and the second heat-sealed electrode block are in the second installation position, the first heat-sealed electrode block and the second heat-sealed electrode block are in a vertical state.

[0012] Optionally, a protective cover is also included. The protective cover is installed on the body of the heat sealing machine and is fitted over the first heat sealing electrode and the second heat sealing electrode. The protective cover has an opening, the position of which corresponds to the gap position between the first heat sealing electrode and the second heat sealing electrode.

[0013] Optionally, the opening includes a placement slot and an insertion slot. There are two placement slots, which are distributed at both ends of the insertion slot and communicate with the insertion slot. The insertion slot is flared.

[0014] Optionally, the protective cover is magnetically fixed to the heat sealing machine body.

[0015] Optionally, the heat sealing machine body is provided with a number of positioning grooves, and the protective cover is fixed with a number of positioning protrusions. The number of positioning protrusions corresponds one-to-one with the number of positioning grooves and can be inserted into the corresponding positioning grooves.

[0016] Optionally, a handle and a base are fixedly connected to the heat sealing machine body, the base is provided with a placement plane, and a battery pack is provided inside the heat sealing machine body for powering the heat sealing machine body.

[0017] Optionally, a power board is provided inside the base, the power board is electrically connected to the battery pack, and a charging interface is provided on the base, the charging interface is electrically connected to the power board, so that an external power source can charge the battery pack through the power board.

[0018] Optionally, a counterweight is fixed inside the base.

[0019] Optionally, the total height of the base after it is fitted with the heat sealing machine body is less than the length of the base.

[0020] This application, by setting up a first installation station and a second installation station, allows for adjustment of the positions of the first and second heat-sealing electrodes. When heat-sealing horizontal pipes is required, the first and second heat-sealing electrodes can be installed at the second installation station; when heat-sealing vertical pipes is required, they can be installed at the first installation station. Through these means, both horizontal and vertical pipes can be heat-sealed, increasing the applicability of the heat-sealing machine.

[0021] Furthermore, this application enables the heat sealing machine to have both tabletop and handheld modes through the design of the base and handle, allowing users to choose the appropriate mode for different usage scenarios. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0029] A heat sealing machine, as shown Figure 1 The heat sealing machine includes a main body 1, a first heat sealing electrode 2, and a second heat sealing electrode 3. The first heat sealing electrode 2 and the second heat sealing electrode 3 are symmetrically arranged and detachably connected to the main body 1 of the heat sealing machine. The second heat sealing electrode 3 can move away from or towards the first heat sealing electrode 2.

[0030] Reference Figure 2 and Figure 3 Specifically, a fixed frame 11 is fixedly installed on the main body 1 of the heat sealing machine, and the first heat sealing electrode 2 is fixedly connected to the fixed frame 11. A drive structure is provided on the main body 1 of the heat sealing machine, and a fixed column 12 is fixedly connected to the drive structure. The drive structure is used to drive the fixed column 12 to move, thereby realizing the movement of the second heat sealing electrode 3 towards or away from the first heat sealing electrode 2. The drive structure driving the second heat sealing electrode 3 to move towards the first heat sealing electrode 2 is the prior art. Specifically, a telescopic motor or other structure that can drive the second heat sealing electrode 3 to move can be used, which will not be described in detail here.

[0031] Reference Figure 1 and Figure 2The heat sealing machine body 1 has a first installation station and a second installation station. When the first heat sealing electrode 2 and the second heat sealing electrode 3 are in the first installation station, the first heat sealing electrode 2 and the second heat sealing electrode 3 are in a horizontal state; when the first heat sealing electrode 2 and the second heat sealing electrode 3 are in the second installation station, the first heat sealing electrode 2 and the second heat sealing electrode 3 are in a vertical state.

[0032] When the pipe to be heat-sealed is placed vertically, a heat-sealing machine with the first heat-sealing electrode 2 and the second heat-sealing electrode 3 located at the first installation position is used. The heat-sealing machine is moved to the position of the vertical pipe so that the vertical pipe is located between the first heat-sealing electrode 2 and the second heat-sealing electrode 3.

[0033] When the pipe to be heat-sealed is placed horizontally, a heat-sealing machine with the first heat-sealing electrode 2 and the second heat-sealing electrode 3 located at the second installation position is used. The heat-sealing machine is moved to the position of the horizontal pipe so that the horizontal pipe is located between the first heat-sealing electrode 2 and the second heat-sealing electrode 3.

[0034] At the factory, heat sealing machines can be manufactured with the first heat sealing electrode 2 and the second heat sealing electrode 3 located at the first installation position, and heat sealing machines can be manufactured with the first heat sealing electrode 2 and the second heat sealing electrode 3 located at the second installation position. When in use, the corresponding heat sealing machine can be used. Alternatively, the first heat sealing electrode 2 and the second heat sealing electrode 3 can be disassembled and their installation positions changed to adapt to pipelines in different conditions.

[0035] Reference Figure 3 Specifically, both the fixing frame 11 and the fixing column 12 are provided with four mounting holes 13, which are arranged in a cross shape. The first heat-sealing electrode 2 is fixed to the fixing frame 11 by two bolts, and the second heat-sealing electrode 3 is fixed to the fixing column 12 by two bolts. The installation methods of the first heat-sealing electrode 2 and the second heat-sealing electrode 3 are the same. The following description takes the installation method of the first heat-sealing electrode as an example.

[0036] The four mounting holes 13 are arranged in pairs, with each pair of mounting holes 13 corresponding to one mounting position. When it is necessary to adjust the mounting position of the first heat-sealing electrode 2, loosen the bolts, rotate the first heat-sealing electrode 2 so that the bolts correspond to the position of the other pair of mounting holes 13, and then install it to change the mounting position of the first heat-sealing electrode 2.

[0037] Reference Figure 4 Furthermore, it also includes a protective cover 4, which is installed on the main body 1 of the heat sealing machine and fitted onto the first heat sealing electrode 2 and the second heat sealing electrode 3. By setting the protective cover 4, the safety of the heat sealing machine can be increased, the occurrence of dust on the user's hands can be reduced, and the protective cover 4 can reduce the occurrence of dust on the first heat sealing electrode 2 and the second heat sealing electrode 3.

[0038] The protective cover 4 has an opening 41, the position of which corresponds to the gap between the first heat-sealing electrode 2 and the second heat-sealing electrode 3. The pipe can be moved directly through the opening 41 to the space between the first heat-sealing electrode 2 and the second heat-sealing electrode 3 by moving the heat-sealing machine.

[0039] Furthermore, the opening 41 includes a placement groove 411 and an insertion groove 412. The insertion groove 412 is flared, and there are two placement grooves 411 located at both ends of the insertion groove 412 and communicating with it. The insertion groove 412 facilitates the insertion of the pipe into the protective cover 4, and the placement groove 411 is sized to fit the pipe, making it easy to limit the pipe's movement.

[0040] Furthermore, the protective cover 4 is magnetically fixed to the heat sealing machine body 1. Because the protective cover 4 is magnetically fixed to the heat sealing machine body 1, it is convenient to remove the protective cover 4.

[0041] Furthermore, the heat sealing machine body 1 has several positioning grooves 14, and the protective cover 4 has several positioning protrusions 42 fixedly connected to it. The positions of the positioning protrusions 42 correspond one-to-one with the positions of the positioning grooves 14, and they can be inserted into the corresponding positioning grooves 14. When the positioning protrusions 42 are inserted into the corresponding positioning grooves 14, the protective cover 4 is magnetically attracted to the heat sealing machine body 1, thus fixing the protective cover 4. By setting the positioning grooves 14 and positioning protrusions 42, the position of the protective cover 4 is fixed, preventing the protective cover 4 from rotating due to external factors.

[0042] In this embodiment, four positioning protrusions 42 and four positioning grooves 14 are provided. The four positioning protrusions 42 are in pairs. When the first heat-sealing electrode block 2 and the second heat-sealing electrode block 3 change their installation positions, the protective cover 4 changes its installation position accordingly. Since four positioning protrusions 42 are provided, it is convenient for the staff to control the rotation angle of the protective cover 4.

[0043] Reference Figure 3 Furthermore, a sensor 5 is installed inside the protective cover 4. The sensor 5 is fixedly mounted on the main body 1 of the heat sealing machine. The sensor 5 is used to detect whether there is a pipe between the first heat sealing electrode 2 and the second heat sealing electrode 3. When the heat sealing machine is started, if the sensor 5 detects a pipe, heat sealing begins; otherwise, heat sealing will not occur. In this embodiment, an infrared sensor 5 can be used. When the infrared light of the infrared sensor 5 is blocked, it is determined that a pipe exists; otherwise, it is determined that there is no pipe. In other embodiments, other sensors 5 can also be used, such as a gravity sensor 5.

[0044] Reference Figure 5Furthermore, a handle 6 and a base 7 are fixedly connected to the heat sealing machine body 1. The handle 6 is fixed to the top surface of the heat sealing machine body 1, and the base 7 is fixed to the bottom surface of the heat sealing machine body 1. A placement plane 71 is provided on the base 7, through which the heat sealing machine body 1 can be stably placed on the workbench or other positions. A battery pack 8 is provided inside the heat sealing machine body 1, which is used to power the heat sealing machine body 1.

[0045] The handle 6 and base 7 allow for two usage modes for the heat sealing machine: handheld and tabletop. When used handheld, the heat sealing machine body 1 is powered by the battery pack 8. The electrical energy is used to operate the drive components, the first heat sealing electrode 2, the second heat sealing electrode 3, and other components. This power supply method is existing technology and will not be described in detail here.

[0046] In handheld mode, the first heat-sealing electrode 2 and the second heat-sealing electrode 3 can be located at either the first or second installation position to accommodate horizontally or vertically installed pipes. In benchtop mode, the first heat-sealing electrode 2 and the second heat-sealing electrode 3 are located at the second installation position, and the pipe is placed between the first heat-sealing electrode 2 and the second heat-sealing electrode 3 for heat sealing. Because the handheld mode requires the heat sealing machine to be moved to fit the pipe, the application scenario is often where the pipe is not easily moved. Therefore, the first heat-sealing electrode 2 and the second heat-sealing electrode 3 need to change their installation positions to fit the pipe. In benchtop mode, the pipe is usually easy to move, and the pipe is moved to fit the heat sealing machine. In this mode, the first heat-sealing electrode 2 and the second heat-sealing electrode 3 can simply be located at the second installation position.

[0047] Furthermore, a power board 72 is provided inside the base 7, which is electrically connected to the battery pack 8. A charging interface 74 is provided on the base 7, which is electrically connected to the power board 72. In desktop mode, an external power supply can be directly connected to the power board 72 through the charging interface 74, thereby charging the battery pack 8 through the power board 72.

[0048] Furthermore, a counterweight 73 is fixedly connected inside the base 7. The counterweight 73 increases the weight of the base 7, making the heat sealing machine more stable and less prone to displacement due to external factors under the tabletop model.

[0049] Furthermore, the total height of the base 7 after it is combined with the main body 1 of the heat sealing machine is less than the length of the base 7. By limiting the height, the entire heat sealing machine is made to have a horizontal structure with a low center of gravity, which further increases the stability in the tabletop mode.

[0050] Furthermore, a light panel (not shown in the figure) is installed inside the handle 6. When the heat sealing machine is in standby mode, the light panel lights up green; when the heat sealing machine is performing heat sealing, the light panel lights up red; and when the heat sealing machine's power is low, the light panel lights up yellow. A light guide strip 9 is fixedly connected to the handle 6, and the light emitted by the light panel is guided out through the light guide strip 9 for easy viewing by the staff.

[0051] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
