[0027] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figures 1 to 2As shown, an embodiment of this utility model provides a heat sealing device, including a heat sealing body 10, a hot electrode head 20 mounted on the heat sealing body 10, and a cold electrode head 30 slidably mounted on the heat sealing body 10; the hot electrode head 20 is provided with a first heat sealing surface 21, and the cold electrode head 30 is provided with a second heat sealing surface 31 at a position opposite to the hot electrode head 20; the cold electrode head 30 is used to adjust the width of the heat sealing gap between the first heat sealing surface 21 and the second heat sealing surface 31 when sliding relative to the heat sealing body 10; the hot electrode head 20 is used to perform hot-press sealing on the workpiece to be heat sealed in the heat sealing gap after heating; the first heat sealing surface 21 is provided with at least two first heat sealing protrusions 211, and the second heat sealing surface 31 is provided with at least two second heat sealing protrusions 311; all the first heat sealing protrusions 211 and all the second heat sealing protrusions 311 are arranged in a one-to-one correspondence. In this embodiment, the cold electrode head 30 can slide relative to the heat-sealing body 10, thereby causing relative movement between the cold electrode head 30 and the heat electrode head 20 fixedly mounted on the heat-sealing body 10. This allows the second heat-sealing surface 31 to move closer to or further away from the first heat-sealing surface 21, changing the width of the heat-sealing gap between the first heat-sealing surface 21 and the second heat-sealing surface 31. Understandably, when a heat-sealing operation is required on a component to be heat-sealed (such as a liquid bag, tubing, or other consumable), the heat electrode head 20 must first be heated, and then... The part to be heat-sealed is placed in the heat-sealing gap, and the cold electrode head 30 is controlled to slide relative to the heat-sealing body 10, so that the second heat-sealing surface 31 moves closer to the first heat-sealing surface 21 until the part to be heat-sealed is pressed tightly onto the first heat-sealing surface 21 by the second heat-sealing surface 31. At this time, since the part to be heat-sealed is in contact with the first heat-sealing surface 21, the part to be heat-sealed can be heat-pressed and sealed by the heat of the first heat-sealing surface 21 after it has been heated. That is, after the part to be heat-sealed is statically heated for an appropriate time, the heat-sealing of the part to be heat-sealed can be achieved.

[0031] In this embodiment, since the first heat-sealing surface 21 is provided with at least two first heat-sealing protrusions 211, and the second heat-sealing surface 31 is provided with at least two second heat-sealing protrusions 311 corresponding to the first heat-sealing protrusions 211, when the first heat-sealing surface 21 is pressed by the second heat-sealing surface 31, the heat-sealing position on the part to be heated is the position opposite to all the first heat-sealing protrusions 211. At this time, there are at least two heat-sealing positions. Compared with the solution with only one heat-sealing position, the heat-sealing strength and reliability are obviously improved by having at least two heat-sealing positions.

[0032] In the heat-sealing device of the above embodiments of this utility model, after the heating electrode head 20 heats the workpiece, if it is necessary to perform heat-press sealing, the workpiece is placed into the heat-sealing gap. Then, by sliding the cold electrode head 30 relative to the heat-sealing body 10, the width of the heat-sealing gap between the first heat-sealing surface 21 and the second heat-sealing surface 31 is adjusted to clamp the workpiece between the first heat-sealing surface 21 and the second heat-sealing surface 31. Then, through the relative pressing between at least two first heat-sealing protrusions 211 on the first heat-sealing surface 21 and the second heat-sealing protrusions 311 on the second heat-sealing surface 31, the heat from the heated first heat-sealing protrusions 211 is used to perform heat-press sealing on the workpiece. Thus, at least two heat-sealing positions corresponding to the at least two first heat-sealing protrusions 211 are formed on the workpiece, thereby improving the heat-sealing strength and reliability of the corresponding heat-sealing positions during each heat-press sealing operation. Furthermore, the heat-sealing device of this utility model has a simple structure, small size, and is easy to carry.

[0033] In one embodiment, at least two of the first heat-sealing protrusions 211 intersect at a first heat-sealing point; at least two of the second heat-sealing protrusions 311 intersect at a second heat-sealing point; the first heat-sealing point and the second heat-sealing point are arranged opposite to each other. That is, as shown... Figure 1 and Figure 2 As shown, in this embodiment, at least two first heat-sealing protrusions 211 can intersect at the first heat-sealing point, and correspondingly, at least two second heat-sealing protrusions 311 intersect at the second heat-sealing point. Thus, the shape of the heat-sealing position on the part to be heat-sealed can be constructed according to actual needs. Understandably, when there are multiple first heat-sealing protrusions 211 and second heat-sealing protrusions 311, the number of first and second heat-sealing points can be set according to requirements and is not limited to one. Furthermore, in... Figure 1 and Figure 2 In the illustrated embodiment, the first heat-sealing surface 21 is provided with three first heat-sealing protrusions 211, and the first ends of the three first heat-sealing protrusions 211 converge at the first heat-sealing point; the second ends of the three first heat-sealing protrusions 211 are spaced apart; the second heat-sealing surface 31 is provided with three second heat-sealing protrusions 311, and the first ends of the three second heat-sealing protrusions 311 intersect at the second heat-sealing point; the second ends of the three second heat-sealing protrusions 311 are spaced apart. Thus, a triangular heat-sealing portion can be formed on the workpiece to be heat-sealed. Understandably, the three first heat-sealing protrusions 211 can also be heat-sealed at different positions on the workpiece. For example, when the workpiece is a conduit, the three first heat-sealing protrusions 211 can be heat-sealed at three positions on the same conduit (the conduit contacts the three first heat-sealing protrusions 211 respectively, and the contact positions are not at the positions corresponding to the first heat-sealing point), in which case a triangular heat-sealing portion will not be formed.

[0034] In one embodiment, the heat-sealing device further includes a heating component connected to the hot electrode head 20 and used to heat the hot electrode head 20. Understandably, the heating component can be connected to the positive and negative electrodes of the hot electrode head 20 to heat the hot electrode head 20. Understandably, the heating component can include, but is not limited to, a battery installed in the heat-sealing body 10, so that the hot electrode head 20 can be heated by current transmitted from the battery to the hot electrode head 20.

[0035] In one embodiment, such as Figure 1 As shown, the heat-sealing body 10 is provided with a mounting groove 11, and the heat electrode head 20 is provided with a mounting protrusion 22. The heat electrode head 20 is mounted in the mounting groove 11 through the mounting protrusion 22. That is, in this embodiment, the heat electrode head 20 can be engaged in the mounting groove 11 by the mounting protrusion 22.

[0036] The heat-sealing body 10 is provided with a mounting post, and the heat electrode head 20 is provided with a mounting hole. The heat electrode head 20 is fitted onto the mounting post through the mounting hole. That is, in this embodiment, the heat electrode head 20 can be connected to the heat-sealing body 10 by fitting the mounting hole onto the mounting post.

[0037] In this invention, the heating electrode head 20 can be provided with both a mounting protrusion 22 and a mounting hole, and the heat-sealing body 10 can be provided with both a mounting groove 11 and a mounting post. Thus, the connection between the heat-sealing body 10 and the heating electrode head 20 is stable through these two connection methods. It is understood that other connection methods can also be used between the heat-sealing body 10 and the heating electrode head 20, and are not limited here.

[0038] In one embodiment, such as Figure 1 As shown, the heat-sealing device further includes a sliding assembly 40, through which the cold electrode head 30 is slidably mounted on the heat-sealing body 10. That is, in this embodiment, the sliding assembly 40 is necessary to achieve a sliding connection between the cold electrode head 30 and the heat-sealing body 10. Further, as... Figure 1As shown, the heat-sealing body 10 has an installation space and an opening 12 communicating with the installation space. The sliding component 40 includes a sliding block 41 and a slide rail disposed on the inner sidewall of the installation space. One end of the sliding block 41 is connected to the cold electrode head 30, and the other end of the sliding block 41 extends through the opening 12 into the installation space and is slidably connected to the slide rail. That is, in this embodiment, the cold electrode head 30 is fixedly connected to the sliding block 41, while the slide rail is disposed on the heat-sealing body 10, and the sliding block 41 is slidably connected to the slide rail. Therefore, the cold electrode head 30 can slide relative to the heat-sealing body 10 through the sliding between the sliding block 41 and the slide rail. Furthermore, in this embodiment, the slide rail is disposed in the installation space, and the sliding block 41 can slide through the opening 12 and be slidably connected to the slide rail in the installation space, while the cold electrode head 30 is disposed outside the installation space, which can realize relative movement with the heat electrode head 20.

[0039] In one embodiment, such as Figure 1 As shown, the heat sealing device further includes a protective head 5 mounted on the heat sealing body 10. The protective head 5 is provided with a protective space 51 and a through hole 52 communicating with the protective space 51. The heat sealing body 10 is disposed at the end of the through hole 52 away from the protective space 51. The hot electrode head 20 extends into the protective space 51 through the through hole 52, and the first heat sealing surface 21 is located in the protective space 51. The sliding component 40 extends into the protective space 51 through the through hole 52 to drive the cold electrode head 30 to move relative to the hot electrode head 20 in the protective space 51, thereby adjusting the width of the heat sealing gap in the protective space 51. That is, in this embodiment, the protective head 5 is fixedly installed on the heat-sealing body 10, and the end of the hot electrode head 20 away from the heat-sealing body 10 passes through the through hole 52. At this time, the supporting force of the through hole 52 can make the installation of the hot electrode head 20 more stable. The sliding component 40 extends into the protective space 51 through the through hole 52, so that the sliding of the sliding component 40 will not be interfered with by the protective head 5. Moreover, the first heat-sealing surface 21 of the hot electrode head 20 and the cold electrode head 30 are both located in the protective space 51. The cold electrode head 30 can move relative to the hot electrode head 20 in the protective space 51, thereby adjusting the width of the heat-sealing gap in the protective space 51. In this way, the heat-sealing part to be heat-sealed can be carried out in the protective space 51, which plays a protective role in the heat-sealing and processing process and avoids interference with the heat-sealing operation.

[0040] In one embodiment, the protective head 5 is provided with a mounting block 53, the heat-sealing body 10 is provided with a first mounting hole 13, and the mounting block 53 is provided with a second mounting hole 531. The protective head 5 is fixedly mounted on the heat-sealing body 10 by screws passing through the first mounting hole 13 and the second mounting hole 531. That is, in this embodiment, the protective head 5 can be securely mounted on the heat-sealing body 10 by means of screw connection.

[0041] This utility model also provides a heat sealing device, including a snap-fit ​​component and the aforementioned heat sealing device; the snap-fit ​​component is provided with a clamping groove for clamping and fixing the component to be heat-sealed; the heat sealing device is used to move to perform heat-press sealing on the component to be heat-sealed, which is fixed in the clamping groove and located in the heat sealing gap. Understandably, in the heat sealing device of this embodiment, the component to be heat-sealed can be clamped and fixed by the snap-fit ​​component to maintain the stability of the component's state. Therefore, only the heat sealing gap of the heat sealing device needs to be aligned with the component to be heat-sealed to perform the heat-press sealing operation, improving the efficiency and stability of repeated heat-press sealing operations.

[0042] In the heat sealing device of the above embodiments of this utility model, after the heat electrode head 20 of the heat sealing device is heated, if it is necessary to perform heat sealing on the workpiece to be heat sealed, the workpiece to be heat sealed is placed into the heat sealing gap. Then, by the relative sliding of the cold electrode head 30 relative to the heat sealing body 10, the width of the heat sealing gap between the first heat sealing surface 21 and the second heat sealing surface 31 is adjusted so that the workpiece to be heat sealed is clamped between the first heat sealing surface 21 and the second heat sealing surface 31. Then, by the relative pressing between at least two first heat sealing protrusions 211 on the first heat sealing surface 21 and the second heat sealing protrusions 311 on the second heat sealing surface 31, the heat from the heating of the first heat sealing protrusions 211 is used to perform heat sealing on the workpiece to be heat sealed. In this way, at least two heat sealing positions corresponding to at least two first heat sealing protrusions 211 will be formed on the workpiece to be heat sealed, thereby improving the heat sealing strength and reliability of the corresponding heat sealing positions during each heat sealing operation of the workpiece to be heat sealed.

[0043] In one embodiment, the heat sealing device further includes a protective head 5 mounted on the heat sealing body 10. The protective head 5 has a protective space 51 and a through hole 52 communicating with the protective space 51. The heat sealing body 10 is disposed at the end of the through hole 52 away from the protective space 51. The heat electrode head 20 extends into the protective space 51 through the through hole 52, and the first heat sealing surface 21 is located in the protective space 51. The snap-fit ​​component also has a guide groove communicating with the clamping groove, and the heat electrode head 20 has a guide portion 23 adapted to the guide groove. When the heat electrode head 20 slides to the bottom of the guide groove through the guiding action of the guide portion 23, the snap-fit ​​component is snapped into the protective space 51, and the workpiece to be heat sealed, which is fixed in the clamping groove, is located in the heat sealing gap.

[0044] In this embodiment, the protective head 5 is fixedly installed on the heat-sealing body 10, while the end of the hot electrode head 20 away from the heat-sealing body 10 passes through the through hole 52. At this time, the supporting force of the through hole 52 can make the installation of the hot electrode head 20 more stable. Furthermore, the sliding component 40 extends into the protective space 51 through the through hole 52, so that the sliding of the sliding component 40 will not be interfered with by the protective head 5. Moreover, the first heat-sealing surface 21 of the hot electrode head 20 and the cold electrode head 30 are both located in the protective space 51. The cold electrode head 30 can move relative to the hot electrode head 20 in the protective space 51, thereby adjusting the width of the heat-sealing gap in the protective space 51. In this way, the heat-sealing operation of the part to be heat-sealed can be carried out in the protective space 51, which plays a protective role in the heat-sealing and processing process and avoids interference with the heat-sealing operation.

[0045] Meanwhile, a guide portion 23 is provided on the part of the hot electrode head 20 that extends into the protective space 51. This guide portion 23 is adapted to the guide groove on the snap-fit ​​component. When the protective head 5 of the heat sealing device is moved until the guide portion 23 moves to be opposite to the guide groove, the protective space 51 is also opposite to the snap-fit ​​groove. At this time, when the protective head 5 is moved downward, the guide portion 23 can enter the guide groove and slide downward along the guide groove. The snap-fit ​​component will also be snapped into the protective space 51 to limit the shaking of the protective head 5. When the guide portion 23 slides to the bottom of the guide groove, the protective head 5 can no longer move downward. At this time, if the component to be heat sealed has been clamped and fixed in the snap-fit ​​groove, the component to be heat sealed will be exactly located in the heat sealing gap. Then, the heat sealing operation can be directly performed on the component to be heat sealed. It can be understood that through the combined use of the above-mentioned heat sealing device and snap-fit ​​component, the protective head 5 can be quickly positioned on the component to be heat sealed, improving the efficiency and consistency of repeated heat sealing operations.

[0046] The above are merely embodiments of the heat sealing device and heat sealing equipment of this utility model, and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
