[0051] Combine the following Figure 1-Figure 19 The technical solution provided by the utility model is described in more detail.

[0052] Embodiment 1:

[0053] The utility model provides a heat sealing machine, comprising a machine body and a core mold 1 and a side pressing part 2 located on the machine body, wherein: a heating element and a cutting element are fixed on the core mold 1, and the heating element and the cutting element are at least located on the side of the core mold 1; the side pressing part 2 is located on one side or two pairs of sides of the core mold 1, and the side pressing part 2 is rotatably connected to the machine body, and the side pressing part 2 can be rotated to a position against the side of the core mold 1, thereby heat-sealing the material clamped between the core mold 1 and the side pressing part 2.

[0054] See also Figure 1-Figure 6 As shown, in the heat sealing machine of this embodiment, two side pressing parts 2 are located on opposite sides of the core mold 1, and the two side pressing parts 2 rotate toward or away from each other. A pressing strip 21 is fixed on the side pressing part 2, and the pressing strip 21 is used to press the materials together, thereby heat-sealing the two materials.

[0055] The heat sealing machine of this embodiment aligns the positions of the two materials to be heat-sealed up and down, and wraps them around the core mold 1. The side pressing plate rotates horizontally on the machine body, and the side pressing part 2 can rotate to a position against the side of the core mold 1. The heating element heat-seals the material clamped between the core mold 1 and the side pressing part 2, and the cutting element cuts off the excess material, thereby completing the heat sealing of the two materials. Compared with the vertical pressing method, the heat sealing machine of this embodiment has better safety and good visual effect, is conducive to the alignment of the positions to be connected between the two materials, and improves the processing efficiency, especially suitable for the heat sealing of arc-shaped connection positions, such as the heat sealing of the raincoat body and the hat, and the heat sealing of the raincoat body and the sleeves.

[0056] The heating method can be electric heating wire, heating plate, high frequency heating and the like.

[0057] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the heat sealing machine includes a driving device, which includes a rotary cylinder 3. The rotary cylinder 3 is drivingly connected to one end of the side pressing part 2 and is used to drive the side pressing part 2 to rotate in a horizontal plane.

[0058] Alternatively, see Figure 3 and Figure 4 As shown, the driving device includes a power-assisting cylinder 4, which is inclined compared to the horizontal plane. One end of the side pressing part 2 is rotatably connected to the machine body through a shaft 22. The telescopic end of the power-assisting cylinder 4 is drivingly connected to the middle position of the side pressing part 2, and is used to drive the side pressing part 2 to rotate in the horizontal plane with the shaft 22 as the axis.

[0059] Alternatively, see Figure 5 and Figure 6As shown, the heat sealing machine includes a driving device, which includes a rotating cylinder 3 and a boosting cylinder 4. The rotating cylinder 3 is drivingly connected to one end of the side pressing part 2, and is used to drive the side pressing part 2 to rotate in a horizontal plane; the boosting cylinder 4 is inclined compared to the horizontal plane, and one end of the side pressing part 2 is rotatably connected to the machine body through a shaft 22. The telescopic end of the boosting cylinder 4 is drivingly connected to the middle position of the side pressing part 2, and is used to drive the side pressing part 2 to rotate in a horizontal plane with the shaft 22 as the axis.

[0060] The heat sealing machine of this embodiment, through the structure of the above-mentioned driving device, can drive the two side pressing parts 2 to rotate towards or away from each other, thereby clamping the parts to be connected of the two materials. When the side pressing parts 2 press the materials onto the heating element, the two materials melt and bond together, and the cutting part cuts off part of the excess material.

[0061] As an alternative embodiment, see Figure 1 and Fig.19 As shown, the core mold 1 is a conical structure, the core mold 1 has a pointed cone end 11, and the connecting end of the side crimping part 2 and the body is located beside the wide end of the core mold 1; preferably, the angle of the pointed cone end 11 is 5-6°, and the specific angle is not limited.

[0062] See also Fig.19 As shown, a hook groove 17 is provided at the pointed cone end 11, and the hook groove 17 is recessed toward the wide end of the core mold 1. A horizontally extending limiting wall 18 exists on the upper wall of the hook groove 17 to facilitate the positioning of the workpiece.

[0063] When heat-sealing two materials, such as pressing the main body of the raincoat and the hat together, wrap the side of the main body of the raincoat to be connected around the side of the core mold 1, and then wrap the side of the hat to be connected around the side of the core mold 1 and align it with the main body to be connected, wherein the materials of the main body and the hat are all wrapped in the hook groove 17, and the limiting wall 18 prevents the material from separating from the core mold 1, and the side pressing part 2 rotates toward the side of the core mold 1. When the side pressing part 2 is against the side wall of the core mold 1, the heating element melts and bonds the positions of the two materials to be connected, and the cutting element cuts off the excess positions of the two materials after connection.

[0064] The above structure of the core mold 1 and the pointed cone end 11 can prevent the existence of gaps at the positions of the two materials to be connected, thereby ensuring that the positions of the two materials to be connected can be completely heat-sealed.

[0065] The structure of the hook groove 17 and the limiting wall 18 facilitates the material to be laid on the side of the core mold 1, prevents the material from being separated from the core mold 1, and enables the positions of the two materials to be connected to be clamped between the side wall of the core mold 1 and the side pressing part 2.

[0066] As an alternative embodiment, see Figure 7-Figure 9As shown, the heating element includes a heating wire 6, which is wound around the peripheral wall of the core mold 1 for one circle. The heating wire 6 is directly wound outside the peripheral wall of the core mold 1, and the end of the heating wire 6 is fixedly connected to the wide end of the core mold 1 through an elastic member 5.

[0067] The elastic member 5 tightens the heating wire 6 to prevent the heating wire 6 from shifting sideways from the core mold 1 due to thermal expansion and contraction.

[0068] As an alternative embodiment, see Figure 7-Figure 9 As shown, the cutting element includes a cutting wire 7, which is located above the heating element and is wound around the peripheral wall of the core mold 1; the cutting wire 7 is directly wound outside the peripheral wall of the core mold 1, and the end of the cutting wire 7 is fixedly connected to the wide end of the core mold 1 through an elastic member 5; the elastic member 5 tightens the cutting wire 7 to prevent the cutting wire 7 from shifting to the side of the core mold 1 under the thermal expansion and contraction performance. The elastic member 5 can be a reset spring.

[0069] As an alternative embodiment, see Fig. 9 As shown, the cutting element includes a cutting wire 7, the cross section of which is circular; the heating element includes a heating wire 6, the cross section of which is a flat structure, and the cross-sectional area of ​​the cutting wire 7 is smaller than the cross-sectional area of ​​the heating wire 6.

[0070] The cross section of the wire cutter 7 is circular, which minimizes the contact area between the wire cutter 7 and the material, so that the wire cutter 7 can quickly cut excess material when the side pressing part 2 abuts against the core mold 1.

[0071] The cross section of the heating wire 6 is a flat structure, which ensures the contact area between the cut wire 7 and the material as much as possible, so that the heating wire 6 can fully contact the material when the side pressing part 2 abuts against the core mold 1, thereby melting the material and facilitating full bonding between the two materials.

[0072] The core mold 1 of this structure is easy to manufacture, but since there is no external force from the elastic member 5, the heating wire 6 and the cutting wire 7 are easy to break.

[0073] Embodiment 2:

[0074] See also Figure 10-12 As shown, the difference between this embodiment and embodiment 1 is that:

[0075] See also Fig.12 A first embedding groove 13 is opened on the peripheral wall of the core mold 1, and the heating wire 6 is embedded in the first embedding groove 13, and the end of the heating wire 6 is directly fixedly connected to the wide end of the core mold 1.

[0076] See also Fig.12 A second embedding groove 14 is provided on the peripheral wall of the core mold 1 , and the cut wire 7 is embedded in the second embedding groove 14 , and the end of the cut wire 7 is directly fixedly connected to the wide end of the core mold 1 .

[0077] See also Figure 10-12 As shown, the heating wire 6 and the cut wire 7 are embedded in the core mold 1, the first embedding groove 13 can prevent the heating wire 6 from shifting, and the second embedding groove 14 can prevent the cut wire 7 from shifting. Therefore, there is no need for the elastic member 5 to tighten the heating wire 6 and the cut wire 7. The heating wire 6 and the cut wire 7 can be directly fixed on the wide end of the core mold 1, and the structure is simple.

[0078] The core mold 1 of this structure is somewhat difficult to manufacture, but the heating wire 6 and the cutting wire 7 are not easy to break.

[0079] As an optional implementation, the core mold 1 of this embodiment is made of any one of a steel plate, a bakelite plate, an aluminum plate or a glass fiber plate.

[0080] Among them, the steel plate is easy to process, easy to conduct heat, and has high work efficiency, but it is not insulated and cannot be embedded with the heating wire 6 and the cut wire 7. The aluminum plate is more heat-conductive than the steel plate, and its other disadvantages are the same as those of the steel plate; the bakelite plate has good integrity and insulation, and the heating wire 6 and the cut wire 7 can be embedded, and a water-cooling channel 19 can also be set. The disadvantages are poor heat conductivity, easy corrosion, and not resistant to high temperatures. The glass fiber plate is difficult to process, resistant to high temperatures, high in strength, and insulated. The heating wire 6 and the cut wire 7 can be embedded, and a water-cooling channel 19 can also be set, and the heat conductivity is good.

[0081] Embodiment 3:

[0082] See also Fig.16 As shown, the difference between this embodiment and embodiment 1 is that:

[0083] A heat sink 16 is embedded in the core mold 1 . The heat sink 16 is made of a different material from the core mold 1 . The heat sink 16 is embedded in the middle and / or bottom of the core mold 1 and is exposed to the external environment.

[0084] The heat sink 16 is embedded in the middle or bottom of the core mold 1 , or the heat sink 16 is embedded in the middle and bottom of the core mold 1 .

[0085] The heat sink 16 is preferably made of an aluminum plate with good heat dissipation performance to facilitate heat dissipation of the core mold 1.

[0086] When the core mold 1 does not have a heat sink 16, the core mold 1 is preferably made of aluminum or fiberglass, but the aluminum must be well insulated. The outer shells of the heating wire 6 and the cut wire 7 can be covered with insulating cloth.

[0087] Embodiment 4:

[0088] See also Figure 13-Figure 15 As shown, the difference between this embodiment and the above embodiment is that:

[0089] A water cooling channel 19 is constructed in the core mold 1, and an interface 15 is provided on the core mold 1. The interface 15 is connected to the water cooling channel 19 for connecting to an external water source.

[0090] Cold water can flow in the water-cooling channel 19 of the core mold 1, which can reduce the temperature of the core mold 1, prevent the core mold 1 from being too hot, and facilitate heat dissipation.

[0091] Embodiment 5:

[0092] See also Fig.17 and Fig.18 As shown, a clamp 8 is connected to the core mold 1, and the clamp 8 is slidably arranged along the core mold 1 under the action of external force.

[0093] The specific structure of the clamp 8 is not limited. When heat-sealing the raincoat body and the hat, the clamp 8 is convenient for fixing the hat first, and then moving and tightening it before heat-sealing, using the heat-sealing operation of the raincoat body and the hat. When heat-sealing the raincoat body and the sleeves, just push the clamp 8 to the root without affecting each other.

[0094] The heat sealing machine of this embodiment is particularly suitable for heat sealing of two materials whose connecting positions are arc-shaped, such as the main body of a raincoat and a hat, the main body of a raincoat and sleeves, etc., and the two types can be flexibly switched.

[0095] In the description of this specification, specific features, structures or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0096] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0097] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
