[0026] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0027] A temperature-controlled heat-sealing flexible packaging forming machine according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] For easier understanding, see Figures 1 to 4 The present invention provides an embodiment of a temperature-controlled heat-sealed flexible packaging forming machine, comprising a base 1, a replacement mechanism being provided on the top of the base 1, two extension frames 3 being mounted on both sides of the base 1, an expansion shaft 4 being fixedly mounted on one end of the extension frame 3, and a first servo motor 5 being fixedly mounted on a side wall of the extension frame 3 on one side of the base 1;

[0030] The replacement mechanism includes a mounting frame 2, a rotating shaft 16, a heating wire 18, a clamping block 21, a connecting frame 22 and a connecting member 7. The mounting frame 2 is fixedly mounted on the top of the base 1, the rotating shaft 16 is rotatably connected to the inside of the mounting frame 2, a mounting cavity 17 is provided inside the rotating shaft 16, the heating wire 18 is fixedly mounted on the inner wall of the mounting cavity 17, a movable cavity 20 is provided on the inner wall of the mounting cavity 17, the clamping block 21 is installed inside the movable cavity 20, the connecting frame 22 is fixedly mounted on the bottom of the connecting member 7, the side wall of the connecting frame 22 is provided with a clamping groove 23 that fits with the clamping block 21, and a molded part 8 is fixedly mounted on one side of the connecting member 7.

[0031] It should be noted that, by setting up the expansion shaft 4, a heat-sealing film roll for flexible packaging molding can be installed. By setting up the first servo motor 5, the expansion shaft 4 on one side of the extension frame 3 on which the first servo motor 5 is installed can be driven to rotate, so as to pull the heat-sealing film to move and reel it up on the side wall of the expansion shaft 4, thereby allowing the heat-sealing film to move on the top of the base 1. By setting up the heating wire 18, the inside of the installation cavity 17 can be heated, thereby increasing the temperature of the connecting frame 22, the connecting member 7 and the molding member 8. By setting up the rotating shaft 16, the connecting member 7 can be driven to rotate. And the forming part 8 rotates. When the forming part 8 rotates to the bottom of the rotating shaft 16, it will contact the heat-sealing film on the top of the base 1, thereby heating the two layers of heat-sealing film to form a soft package. By setting the card block 21, the connecting frame 22 can be clamped in the rotating shaft 16 through the card slot 23, so that the connecting frame 22 and the connecting member 7 can be disassembled. The connecting member 7 can be replaced by disassembling the connecting member 7, so that the connecting member 7 with different forming parts 8 can be replaced as needed, so that the forming machine can process soft packages of different shapes, making the forming machine more versatile.

[0032] In some embodiments, as Figure 4 As shown, the block 21 is movably connected to the inside of the movable cavity 20 through a spring, the connecting member 7 is an arc-shaped member, and a heat conductor 24 is fixedly installed inside the connecting frame 22. One end of the heat conductor 24 is in contact with the connecting member 7, and the other end of the heat conductor 24 is located on the side of the heating wire 18.

[0033] It should be noted that the temperature control effect can be achieved by controlling the power of the heating wire 18, the block 21 can be pushed to one side by setting a spring, the connecting part 7 can be made to fit the rotating shaft 16 more closely by setting the connecting part 7 as an arc-shaped part, and the temperature inside the installation cavity 17 can be transferred more quickly to the molded part 8 on one side of the connecting part 7 by setting the heat conductor 24, so that the molded part 8 can heat up faster.

[0034] In some embodiments, as Figure 4 As shown, a second servo motor 6 is fixedly mounted on one side of the mounting frame 2 , a connecting end of the rotating shaft 16 is fixedly mounted on the output end of the second servo motor 6 , and a heat insulating pad 19 is fixedly mounted at the connection between the inside of the heating wire 18 and the inner wall of the mounting cavity 17 .

[0035] It should be noted that the second servo motor 6 can drive the rotating shaft 16 to rotate, and the heat insulation pad 19 can prevent the high temperature inside the installation cavity 17 from being transferred to the second servo motor 6, thereby avoiding affecting the operation of the second servo motor 6.

[0036] Example 2

[0037] In some embodiments, as Figure 3As shown, a mounting plate 10 is fixedly installed on the top of the base 1, and a pressure block 12 is movably connected to the inside of the mounting plate 10 through a spring. A movable groove 13 is opened inside the base 1, and an electric push rod 14 is fixedly installed inside the movable groove 13. A support plate 15 is fixedly installed on the output end of the electric push rod 14, and a support member 9 is fixedly installed on the top of the support plate 15. The support member 9 is a semi-arc-shaped member.

[0038] It should be noted that by setting the pressure block 12, the two layers of film on the top of the base 1 can be pressed to prevent them from tilting up. By setting the electric push rod 14, the support plate 15 can be pushed upward, so that the film on the top of the support plate 15 is in closer contact with the molding part 8, so that the flexible packaging molding effect is better. By setting the support part 9, the support effect can be further enhanced.

[0039] The first servo motor 5 , the second servo motor 6 , the electric push rod 14 and the heating wire 18 in the present invention are well-known components and will not be described in detail herein.

[0040] Working principle: When in use, the heat-sealing film roll for installing flexible packaging molding is installed on the side wall of the expansion shaft 4 on the side of the extension frame 3 without the first servo motor 5, and the first servo motor 5 drives the expansion shaft 4 on the side of the extension frame 3 installed with the first servo motor 5 to rotate, so as to pull the heat-sealing film to move and make it roll up on the side wall of the expansion shaft 4, so that the heat-sealing film can be moved on the top of the base 1. By setting the heating wire 18, the inside of the installation cavity 17 can be heated, so that the temperature of the connecting frame 22, the connecting part 7 and the molding part 8 increases. By setting the rotating shaft 16, the connecting part 7 and the molding part 8 can be driven to rotate. When the molding part 8 rotates to the bottom of the rotating shaft 16, it will contact the heat-sealing film on the top of the base 1, thereby heating the two layers of heat-sealing film to form a flexible package. During this process, the electric push rod 14 runs to push the support plate 15 upward, so that the heat-sealing film and the molding part 8 are more completely released, so that the molding effect is better.

[0041] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
