[0027] The following is combined with Figures 1-3 The present invention provides a detailed description of a hot melt tooling through specific embodiments and application scenarios.

[0028] like Figure 1 and Figure 2 As shown, this utility model provides a hot-melt fixture, including: a base 1, a pressure plate 2, and a hot-melt device 3. The base 1 is used to fix the tank body 100 of the humidification tank. The pressure plate 2 is used to press against the metal base plate 101 of the humidification tank. The pressure plate 2 is arranged parallel to the base 1, and the distance between the pressure plate 2 and the base 1 is adjustable. The pressure plate 2 has a through hole, and the hot-melt head 31 of the hot-melt device 3 passes through the through hole to hot-melt the metal base plate 101 to the tank body 100.

[0029] Specifically, the base 1 is made of sturdy metal or composite material, possessing sufficient load-bearing capacity and stability to withstand the weight of the tank 100 and external pressures that may arise during use. The base 1 can be circular, rectangular, or in other shapes depending on actual needs, and its surface can be treated with an anti-slip finish to enhance stability. The base 1 supports and stabilizes the tank 100, ensuring the stability and safety of the tank 100 and the metal base plate 101 during use.

[0030] The pressure holding plate 2 has a high melting point and high strength, so that the pressure holding plate 2 will not be damaged by the hot melt head 31 during the hot melt process of passing through the through hole to melt the hot melt column, thereby ensuring the pressure holding effect of the pressure holding plate 2 on the metal bottom plate 101 of the humidification tank. Optionally, the pressure holding plate 2 is a graphite plate or a titanium plate.

[0031] like Figure 1 As shown, the pressure plate 2 is flat. The pressure plate 2 is located above the base 1, and the pressure plate 2 and the base 1 are arranged parallel to each other. The side of the pressure plate 2 facing the base 1 has a contoured surface, the shape of which is adapted to the shape of the surface of the metal base plate 101, so as to better press the metal base plate 101.

[0032] In use, the tank 100 is inverted and fixed onto the base 1, and the multiple hot-melt holes on the metal base plate 101 are inserted one by one into the multiple hot-melt columns of the tank 100. Then, the pressure plate 2 is pressed down, so that the side of the pressure plate 2 facing the base 1 is tightly fitted with the metal base plate 101, thereby fixing the position of the metal base plate 101 and preventing it from shifting. Next, the hot-melt head 31 is inserted through the through hole by hand using the hot-melt device 3 to melt the hot-melt column, thereby achieving a tight connection between the metal base plate 101 and the tank 100. After the hot-melt is completed, the pressure plate 2 is kept in its current position, and pressure is continued to be applied to the metal base plate 101 to ensure the stability of the hot-melt between the metal base plate 101 and the tank 100, effectively ensuring the fit between the two. After the pressure is maintained, the pressure plate 2 is moved upward, and then the assembled tank 100 and metal base plate 101 can be removed from the base 1.

[0033] This utility model provides a hot-melt fixture. A base 1 is used to fix the tank body 100 of the humidification tank, and a pressure plate 2 is used to press the metal base plate 101 of the humidification tank. The pressure plate 2 is arranged parallel to the base 1, and the distance between the pressure plate 2 and the base 1 is adjustable. When in use, the pressure plate 2 is pressed down to make the pressure plate 2 tightly press against the metal base plate 101, ensuring that the metal base plate 101 will not shift during the hot-melt process. The hot-melt head 31 of the hot-melt device 3 passes through the through hole and melts the hot-melt column on the tank body 100 to achieve the hot-melt connection between the metal base plate 101 and the tank body 100. After the hot-melt is completed, the pressure plate 2 continues to maintain its current position to keep pressure on the metal base plate 101 to ensure the strength and stability of the hot-melt connection between the metal base plate 101 and the tank body 100, effectively ensuring the fit between the two. The metal base plate 101 has high flatness, which improves the factory consistency of the humidification tank.

[0034] In some embodiments, there are multiple through holes. The heat fusion device 3 includes multiple heat fusion heads 31. The multiple heat fusion heads 31 are respectively disposed in the multiple through holes to simultaneously heat fuse multiple connection points between the metal base plate 101 and the tank body 100.

[0035] The hot melt machine 3 can be a multi-head hot melt machine. The number of through holes is consistent with the number of hot melt points on the metal base plate 101 and the tank body 100. The size of each through hole is larger than the size of the hot melt head 31 and the hot melt column to ensure that the hot melt head 31 has sufficient operating space.

[0036] In use, multiple through holes are aligned with multiple hot melt points, and multiple hot melt heads 31 are simultaneously inserted into the multiple through holes to heat melt multiple hot melt points at the same time, ensuring the consistency of heat melting at each hot melt point and improving the heat melting efficiency.

[0037] In some embodiments, such as Figure 1 and Figure 2 The heat fusion fixture also includes a drive assembly 4. The drive assembly 4 is mounted on the base 1. The drive assembly 4 is used to drive the pressure plate 2 closer to or further away from the base 1. When the drive assembly 4 drives the pressure plate 2 closer to the base 1, the pressure plate 2 applies a certain force to the metal base plate 101, ensuring that the metal base plate 101 maintains its position under pressure and guarantees the flatness of the connection between the metal base plate 101 and the tank 100 after heat fusion. Driving the drive assembly 4 away from the base 1 allows the user to easily remove the heat-fused metal base plate 101 and tank 100 from the base 1, ensuring sufficient operating space.

[0038] In one specific embodiment, such as Figure 1 and Figure 3 As shown, the drive assembly 4 includes a rotary drive component 41 and a connecting rod 42. The connecting rod 42 is connected to the pressure plate 2. The rotary drive component 41 is fixed to the base 1. The drive end of the rotary drive component 41 is connected to the connecting rod 42 to drive the connecting rod 42 to move linearly in the vertical direction.

[0039] Specifically, the rotary drive component 41 is mounted on the base 1 via a fixed seat 12. The drive shaft of the rotary drive component 41 extends vertically. The connecting rod 42 is horizontally arranged, and at least a portion of the connecting rod 42 is located above the pressure plate 2. The drive shaft of the rotary drive component 41 is connected to the connecting rod 42 via a transmission system, driving the connecting rod 42 to move linearly in the vertical direction. The pressure plate 2 moves up or down under the drive of the connecting rod 42, thereby adjusting the distance between the pressure plate 2 and the base 1.

[0040] Optionally, the rotary drive 41 can be a rotary cylinder, a stepper motor, or a servo motor.

[0041] In some embodiments, such as Figure 2 As shown, the drive assembly 4 also includes an elastic element 43. One end of the elastic element 43 abuts against the connecting rod 42, and the other end abuts against the pressure plate 2. The extension and retraction direction of the elastic element 43 is consistent with the vertical direction.

[0042] Optionally, the elastic element 43 is a spring. By clamping the spring between the pressure plate 2 and the connecting rod 42, the pressure of the pressure plate 2 on the metal base plate 101 can be precisely adjusted by the extension and contraction of the spring, thereby ensuring the ironing effect of the metal base plate 101 and guaranteeing the consistency of the product.

[0043] In some embodiments, such as Figure 2 As shown, two sets of drive components 4 are provided. The two sets of drive components 4 are located on opposite sides of the pressure plate 2 to simultaneously drive the pressure plate 2 to move closer to or away from the base 1, ensuring that the pressure plate 2 can move smoothly in the vertical direction, preventing the pressure plate 2 from tilting, and ensuring the pressure holding effect of the pressure plate 2 on the metal base plate 101.

[0044] In some embodiments, such as Figure 1 As shown, the base 1 is provided with a mounting groove 11. The mounting groove 11 is used to fix the tank 100.

[0045] The shape and size of the mounting groove 11 match the outline of the tank 100, allowing the tank 100 to be precisely fixed to the base 1. The mounting groove 11 can be a recess or other structure to ensure the stability of the tank 100 within the mounting groove 11. The depth and width of the mounting groove 11 are set according to the specific dimensions of the tank 100 to ensure that it can effectively support the tank 100.

[0046] In some embodiments, the hot melt fixture further includes a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are used to clamp the tank 100. The first clamping plate and the second clamping plate are respectively disposed on both sides of the mounting groove 11, and at least one of the first clamping plate and the second clamping plate is movably disposed on the base 1, so that the first clamping plate and the second clamping plate are close to or far apart from each other.

[0047] The first and second clamping plates can be steel plates. Both the first and second clamping plates are located on the base 1 and are arranged side by side.

[0048] When it is necessary to clamp the tank 100, the first clamping plate and the second clamping plate move closer to each other to clamp the opposite sides of the tank 100, thereby fixing the tank 100. After the heat fusion is completed, the first clamping plate and the second clamping plate move further apart to release the tank 100.

[0049] One of the first clamping plate and the second clamping plate can be fixedly connected to the base 1, while the other is driven by a drive mechanism to move so that the first clamping plate and the second clamping plate can move closer to each other or further apart.

[0050] In one specific embodiment, the hot melt fixture further includes a driving component. A first clamping plate is fixed to one side of the mounting groove 11, and a guide rail is provided on the other side of the mounting groove 11. A second clamping plate is slidably disposed on the guide rail, and the driving end of the driving component is connected to the second clamping plate to drive the second clamping plate to move along the guide rail.

[0051] The guide rail is fixed to the base 1 and extends toward the first clamping plate. The base of the drive unit is fixed to the base 1. The drive end of the drive unit is connected to the second clamping plate to drive the second clamping plate to move along the guide rail, thereby enabling the second clamping plate to move closer to or further away from the first clamping plate.

[0052] Alternatively, both the first and second clamping plates can move relative to the base 1. Two sets of guide rails and drive components are provided, and the two sets of guide rails and drive components are respectively connected to the first and second clamping plates to simultaneously drive the first and second clamping plates to move closer or further apart from each other.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
