[0038] Medical packaging bags require heat sealing during the production process to ensure their airtightness and sterility. During the heat sealing process, excessive temperatures or pressure applied by the heat-sealing components to the product can cause the bag material to over-melt or over-compress, increasing the contact area between the materials and leading to adhesion between the heat-sealing components and the packaging material.

[0039] In view of this, an embodiment of the present invention provides a heat sealing device, which can block the product to be heat-sealed during the heat sealing process, and set an anti-sticking structure between the product to be heat-sealed and the heat-sealing component. The two ends of the anti-sticking structure are connected to the frame, thereby reducing the possibility of contact between the heat-sealing component and the product to be heat-sealed during the heat sealing process, and reducing adhesion between the heat-sealing component and the product to be heat-sealed.

[0040] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0041] like Figure 1 、 Figure 2 、 Figure 3 As shown, a heat sealing device proposed in an embodiment of the present invention is used to reduce adhesion between a heat sealing component 20 and a product to be heat sealed. The heat sealing device includes:

[0042] Rack 10;

[0043] A heat sealing component 20 connected to the frame 10 for heat sealing the product to be heat sealed; and

[0044] The anti-sticking structure 30 has two ends connected to the frame 10 and is located between the product to be heat-sealed and the heat-sealing component 20 .

[0045] In the technical solution adopted in this embodiment, the frame 10 is provided to provide an integral structural framework for the heat sealing device, ensuring structural strength and providing support for the heat sealing component 20. The heat sealing component 20 is connected to the frame 10 and is used to apply heat and pressure to the product to be heat sealed to achieve a heat sealing effect. During the operation of the heat sealing component 20, the surface of the product to be heat sealed will adhere to the heat sealing component 20 under the action of heat and pressure, which is likely to affect product quality and subsequent process steps. To this end, an anti-sticking structure 30 is provided in this embodiment. The anti-sticking structure 30 can be placed between the heat sealing component 20 and the product to be heat sealed. The anti-sticking structure 30 can block the surface of the product to be heat sealed that needs to be heat sealed, thereby reducing the possibility of adhesion to the heat sealing component 20 during the heat sealing process. Moreover, the two ends of the anti-sticking structure 30 are respectively connected to the frame 10, so that the stability of the anti-sticking structure 30 during the heat sealing process can be ensured. The technical solution proposed in the embodiment of the utility model can block the surface of the product to be heat sealed during the heat sealing process, thereby reducing the adhesion between the heat sealing component 20 and the product to be heat sealed.

[0046] Specifically, the heat sealing device includes a frame 10 , a heat sealing component 20 and an anti-sticking structure 30 .

[0047] The frame 10 can be made of metal materials such as stainless steel and iron, and has a certain load-bearing capacity. It can bear the weight of the heat sealing component 20 and other auxiliary components, and can provide support to ensure stability during the heat sealing process.

[0048] The heat sealing component 20 is movably arranged on the frame 10 and can be a heating plate, a heating roller, or a heating block. It can heat the product to be heat-sealed and apply appropriate pressure to the product to be heat-sealed during the heating process, so that the edges of two or more layers of semi-finished products are bonded together to achieve a sealing effect. In addition, according to the different requirements of the material and thickness of the product to be heat-sealed, the heat sealing component 20 applies corresponding temperature and pressure to the product to be heat-sealed, so as to achieve a better heat sealing effect. It is understandable that the thicker the product to be heat-sealed, the greater the temperature and pressure applied; the thinner the product to be heat-sealed, the smaller the temperature and pressure applied. Of course, the heat sealing component 20 can also be equipped with temperature and pressure sensors to achieve precise control and feedback.

[0049] The anti-sticking structure 30 is used to block the surface of the product to be heat-sealed, thereby reducing adhesion between the heat-sealing component 20 and the product to be heat-sealed. It is understood that by providing the anti-sticking structure 30, when the heat-sealing component 20 begins to operate, it can abut against the anti-sticking structure 30, and then apply temperature and pressure to the product to be heat-sealed to complete the heat-sealing operation. During this process, the anti-sticking structure 30 can reduce the contact between the heat-sealing component 20 and the product to be heat-sealed, thereby reducing adhesion between the heat-sealing component 20 and the product to be heat-sealed. The anti-sticking structure 30 provides physical isolation between the heat-sealing component 20 and the product to be heat-sealed, preventing direct contact and thus reducing the possibility of adhesion. At the same time, the anti-sticking structure 30 can protect the surface of the product to be heat-sealed from damage by the heat-sealing component 20, maintaining the integrity of the material. In this way, the heat-sealed product will not adhere to the anti-sticking structure 30. In this embodiment, the surface of the anti-sticking structure 30 can also have a specific texture or microstructure, or be made of a material with a low coefficient of friction, which can further reduce the possibility of adhesion.

[0050] Further, refer to Figure 2 、 Figure 3 In one embodiment of the present invention, the anti-sticking structure 30 includes:

[0051] Mounting rack 31, the mounting rack 31 is provided on the frame 10, and two mounting racks 31 are provided at intervals along the width direction of the product to be heat-sealed, and the two mounting racks 31 are located on both sides of the product to be heat-sealed;

[0052] A mounting rod 32 rotatably connected to the mounting bracket 31 , with each mounting bracket 31 correspondingly provided with a mounting rod 32 ; and

[0053] The first release cloth 33 has one end connected to a mounting rod 32 and the other end connected to another mounting rod 32 so that the release cloth covers the product to be heat-sealed.

[0054] In the technical solution adopted in this embodiment, anti-sticking structure 30 can also include mounting frame 31, mounting rod 32 and first anti-sticking cloth 33. In the present embodiment, mounting frame 31 can provide firm support for anti-sticking structure 30, ensure the stability of anti-sticking structure 30 in use, be provided with a mounting frame 31 on both sides of product to be heat-sealed, like this, can adjust and align first anti-sticking cloth 33, to ensure correct operation and optimal performance. Mounting rod 32 is used to install the first anti-sticking cloth 33, and the mounting rod 32 that is rotatably connected can adjust the looseness of the first anti-sticking cloth 33, and adjustable looseness makes the first anti-sticking cloth 33 can adapt to the material of different thicknesses and properties, ensures that consistent performance can be provided in various applications. The first anti-sticking cloth 33 can be made of the material with high melting point and excellent anti-sticking properties, can keep stable at high temperature, avoid chemical reaction or adhesion with heat-sealed product or heat-sealing component 20. In the present embodiment, the first anti-sticking cloth 33 is fully covered on the surface of product to be heat-sealed, thereby forming a protective layer, reduces the possibility that heat-sealing component 20 contacts with product to be heat-sealed in the heat-sealing process. Moreover, the mounting rod 32 is rotatably connected to the mounting frame 31 , so that the mounting rod 32 can be rotated according to the material and thickness of the product to be heat-sealed, thereby rolling up or unrolling the first anti-sticking cloth 33 to achieve a relatively better anti-sticking effect.

[0055] Further, refer to Figure 3 In one embodiment of the present invention, the anti-sticking structure 30 further includes a rotating rod 34 , which is rotatably connected to the mounting frame 31 , and an end portion of the first anti-sticking cloth 33 is wrapped around the outer periphery of the rotating rod 34 .

[0056] In the technical solution adopted in this embodiment, the rotating rod 34 is provided to provide additional support for the first anti-sticking cloth 33, increase stability, and at the same time help reduce the possibility of wrinkles and deformation of the first anti-sticking cloth 33 during the winding or releasing process. It can also be used to adjust the tension of the first anti-sticking cloth 33 during winding, ensuring that the first anti-sticking cloth 33 is tightly and evenly wound on the mounting rod 32.

[0057] Further, refer to Figure 2 、 Figure 3 In one embodiment of the present invention, the anti-sticking structure 30 further includes:

[0058] Support rods 35 , each mounting bracket 31 is provided with at least one support rod 35 ; and

[0059] The second release cloth 36 has two ends respectively wrapped around the outer periphery of the support rods 35 on the two mounting frames 31 , and the second release cloth 36 abuts against the side of the product to be heat-sealed away from the first release cloth 33 .

[0060] In the technical solution adopted in this embodiment, the anti-sticking structure 30 can also include a support rod 35 and a second anti-sticking cloth 36. The support rod 35 is mainly used to provide a supporting effect, ensure structural strength, and generally adopts sheet metal. The second anti-sticking cloth 36 is arranged on the support rod 35, and is mainly used to support the heat-sealed product, and can reduce the possibility of the heat-sealed product sagging due to the pressure applied by the heat-sealing component 20. In the present embodiment, the support rod 35 on each mounting frame 31 can be set to one, or it can be set to multiple, and is not limited here. In the following description, it is introduced as an example to be set to one. The two ends of the second anti-sticking cloth 36 can be respectively wrapped around the support rod 35 located on both sides of the heat-sealed product, and the second anti-sticking cloth 36 is rolled up by rotating the support rod 35, so that the second anti-sticking cloth 36 is tightened until it abuts against the side of the heat-sealed product away from the first anti-sticking cloth 33. At this time, the second anti-sticking cloth 36 can provide support for the side of the heat-sealed product away from the heat-sealing component, reducing the possibility of the heat-sealed product sagging causing deformation or wrinkles in the heat-sealing process. The second release cloth 36 can ensure that the product to be heat-sealed remains flat during the heat-sealing process, thereby improving the accuracy and consistency of the heat-sealing.

[0061] Further, refer to Figure 2 、 Figure 3 In one embodiment of the present invention, the anti-sticking structure 30 also includes an adjustment portion 40, and two adjustment portions 40 are arranged at intervals along the height direction of the mounting frame 31, one adjustment portion 40 is connected to the mounting rod 32, and the other adjustment portion 40 is connected to the support rod 35.

[0062] In the technical solution adopted in this embodiment, the adjustment portion 40 can be a handle. By providing two handles, one handle is connected to the mounting rod 32, and the other handle is connected to the support rod 35. It is understood that during the heat sealing process, when it is necessary to adjust the tension of the first release cloth 33 or the second release cloth 36, the first release cloth 33 or the second release cloth 36 can be rolled up or unrolled by rotating the handle, so that the first release cloth 33 or the second release cloth 36 is evenly tightened, ensuring that the first release cloth 33 or the second release cloth 36 performs best during the heat sealing process.

[0063] Further, refer to Figure 4 In one embodiment of the present invention, the adjusting portion 40 includes a bolt 41 and a nut 42. The bolt 41 is connected to the mounting rod 32 or the support rod 35. The nut 42 is threadedly connected to the bolt 41. The nut 42 moves toward the mounting frame 31 until it abuts against the mounting frame 31 to fix the bolt 41. The nut 42 moves toward the mounting frame 31 and separates from the mounting frame 31, so that the bolt 41 rotates the mounting rod 32 or the support rod 35 under the action of external force.

[0064] In the technical solution adopted in this embodiment, adjusting portion 40 can also include bolt 41 and nut 42. In the present embodiment, bolt 41 can be connected with mounting rod 32 or support rod 35, and nut 42 is threadedly connected with bolt 41. When it is necessary to rotate mounting rod 32, first unscrew nut 42 so that bolt 41 can be rotated, then determine the required tightness according to application requirements, after completing adjustment, tighten nut 42 again so that nut 42 moves towards the direction close to mounting frame 31 until it abuts mounting frame 31, so that bolt 41 is fixed. In the present embodiment, by the arrangement of bolt 41 and nut 42, the tension force of the first anti-sticking cloth 33 or the second anti-sticking cloth 36 can be accurately controlled, and accurate adjustment is achieved. It is understandable that a handheld portion is fixedly connected to the end of bolt 41 for convenient rotation of bolt 41.

[0065] Further, refer to Figure 3 In one embodiment of the present invention, the anti-sticking structure 30 also includes a limiting member 50, which is movably arranged on the mounting frame 31. Each adjustment portion 40 is correspondingly provided with a limiting member 50. The limiting member 50 moves toward the direction approaching the adjustment portion 40 so that the limiting member 50 abuts against the adjustment portion 40, or the limiting member 50 moves toward the direction away from the adjustment portion 40 so that the limiting member 50 is separated from the adjustment portion 40.

[0066] In the technical solution adopted in this embodiment, the anti-sticking structure 30 may further include a limiter 50, which may be the above-mentioned bolt. By tightening the bolt, the end of the bolt moves in a direction close to the adjusting portion 40 until the bolt is pressed against the adjusting portion 40, thereby fixing the adjusting portion 40. At the same time, by loosening the bolt, the end of the bolt moves in a direction away from the adjusting portion 40 until the bolt is separated from the adjusting portion 40, thereby allowing the adjusting portion 40 to perform an adjustment operation. It is understandable that the limiter 50 provided can ensure that the adjusting portion 40 is accurately positioned in the desired position, thereby improving the accuracy of the overall structure. At the same time, the limiter 50 can reduce the movement of components to a position beyond a predetermined range due to accidents or operational errors, thereby avoiding potential damage or malfunction. Moreover, after long-term use, components may become loose due to wear. The limiter 50 can provide additional locking to reduce the possibility of loosening.

[0067] Further, refer to Figure 1 、 Figure 2 In one embodiment of the present invention, the heat sealing component 20 includes:

[0068] A heat sealing block 21 is provided on the frame 10; and

[0069] The support platform 22 is provided on the frame 10 and is located on a side of the product to be heat-sealed away from the heat-sealing block 21 , and is used to support the product to be heat-sealed when the heat-sealing block 21 is working.

[0070] In the technical solution adopted in this embodiment, the heat sealing component 20 also includes a heat sealing block 21 and a support platform 22. In this embodiment, the heat sealing block 21 is movably arranged on the frame 10, and the heat sealing block 21 can be driven by a motor or a cylinder to move relative to the frame 10, thereby heat-sealing the product to be heat-sealed. The support platform 22 is used to support the edge of the product to be heat-sealed, so that the position where the product to be heat-sealed needs to be heat-sealed can be better stressed, reducing the possibility of deformation or collapse of the product to be heat-sealed. It is understandable that the support platform 22 can be fixedly connected to the frame 10 and set to be integrally formed, which can provide better overall structural strength and stability; it can also be set separately from the frame 10 to provide greater flexibility.

[0071] Further, refer to Figure 1 In one embodiment of the present invention, the length of the heat sealing block 21 is greater than 120 cm; or

[0072] The length of the heat sealing block 21 is equal to 120 cm.

[0073] In the technical solution adopted in this embodiment, by setting the length of the heat sealing block 21 to be greater than or equal to 120 cm, a sufficient heat sealing area can be provided. That is, the length of the heat sealing block 21 that can apply heat and pressure to the product to be heat-sealed can be increased, so that a longer length of the product to be heat-sealed can be heat-sealed at the same time, thereby improving the heat sealing efficiency.

[0074] Further, refer to Figure 1 In one embodiment of the present invention, the heat sealing device further includes a conveying assembly 60 , which is connected to the frame 10 to convey the product to be heat sealed through the frame 10 .

[0075] In the technical solution adopted in this embodiment, a conveyor assembly 60 is provided to move the product to be heat-sealed into the frame 10, thereby completing the heat-sealing operation. In this embodiment, the conveyor assembly 60 may include a conveyor belt or rollers for carrying and moving the product to be heat-sealed. The conveyor belt or rollers guide the product to be heat-sealed along a predetermined path, ensuring that the product passes through the heat-sealing area at a constant speed. Furthermore, the conveyor belt or rollers can control the conveying speed and position to accommodate different heat-sealing requirements.
