At this time, the two first hot melt blocks 41 are relatively slid until the packaging materials on the two sides of the self-heating package 61 in the length direction are heat sealed together. Meanwhile, the packaging materials on the two sides of the self-heating package 61 in the width direction are heat sealed together by the two groups of second hot melt blocks 42, so as to form a heat sealed bag, thereby completing the packaging of the self-heating package 61. It should be noted that the packaging material in the embodiment can be a plastic packaging paper known to those skilled in the art.

[0049] Based on the above overall introduction, in the embodiment, as a preferred implementation form, as shown in Figure 1 and Figure 2 The conveying mechanism 2 includes a first support 21, a second support 22, a third support 23, two first rotating shafts 24, two second rotating shafts 25, a first conveying belt 26 sleeved on the two first rotating shafts 24 and a second conveying belt 27 sleeved on the two second rotating shafts 25. The two first rotating shafts 24 are respectively rotatably arranged on the first support 21 and the second support 22. The two second rotating shafts 25 are respectively rotatably arranged on the second support 22 and the third support 23. The first conveying belt 26 is used for conveying the self-heating package 61 and part of the packaging material. The second conveying belt 27 is used for conveying the self-heating package 61 after packaging.

[0050] Here, the first support 21, the second support 22 and the third support 23 are arranged to provide installation space for the first rotating shaft 24 and the second rotating shaft 25. The first conveying belt 26 is sleeved on the two first rotating shafts 24, and the second conveying belt 27 is sleeved on the two second rotating shafts 25, so as to ensure the smooth transportation of the packaging material and the self-heating package 61.

[0051] In the specific structure, the first support 21, the second support 22 and the third support 23 are all arranged in a U shape. Of course, they can also be designed and adjusted according to actual needs. The part of the packaging material is the lower packaging material 63 described below. In the embodiment, a first motor 241 is connected to one of the first rotating shafts 24, and a second motor 251 is connected to one of the second rotating shafts 25. Under the drive of the first motor 241, the two first rotating shafts 24 can drive the first conveying belt 26 to move. Under the drive of the second motor 251, the two second rotating shafts 25 can drive the second conveying belt 27 to move.

[0052] Specifically, in the embodiment, as a preferred implementation form, as shown in Figure 2 and Figure 3As shown in the figure, the second support 22 is provided with a driving shaft 43 extending along the height direction of the chassis 1, the driving shaft 43 is slidably provided with a mounting plate 44 corresponding to each first hot melt block 41, and the driving shaft 43 is provided with a threaded section 431, and the first hot melt block 41 slides on the threaded section 431 through the corresponding mounting plate 44.

[0053] Here, by providing the driving shaft 43 and the threaded section 431 on the driving shaft 43, the two mounting plates 44 can drive the corresponding first hot melt blocks 41 to slide up and down relative to each other, thereby facilitating heat sealing of the packaging material. In the specific structure, the driving shaft 43 of the present embodiment is arranged at a distance along the width direction of the chassis 1, and the threaded section 431 on each driving shaft 43 is arranged at a distance along the height direction of the chassis 1. The two threaded sections 431 correspond to the two mounting plates 44 one by one, and the two threaded sections 431 are symmetrically arranged.

[0054] In specific implementation, the third motor 432 is connected to each driving shaft 43, and under the driving of the third motor 432, each driving shaft 43 rotates and drives the corresponding mounting plate 44 to slide through the two threaded sections 431 on the driving shaft 43, thereby causing the two first hot melt blocks 41 to approach each other and heat seal the packaging material.

[0055] Further, in the present embodiment, as a preferred implementation form, as shown in Figure 3 , Figure 4 and Figure 5 , each first hot melt block 41 is clamped to the bottom of the corresponding mounting plate 44 by a clamping structure 45. Here, the first hot melt block 41 is clamped to the bottom of the mounting plate 44 by the clamping structure 45, which can realize the detachable connection between the first hot melt block 41 and the mounting plate 44, facilitating the maintenance and replacement of the first hot melt block 41.

[0056] Moreover, the clamping structure 45 includes a clamping strip 451 provided in the first hot melt block 41, a clamping groove 452 provided on the mounting plate 44 and adapted to the clamping strip 451, and a driving member 453 for driving the clamping strip 451 to be clamped in the clamping groove 452. It can be understood that the clamping structure 45 includes the clamping strip 451, the clamping groove 452 and the driving member 453, which are cooperatively arranged between the driving member 453 and the clamping strip 451, so that the clamping strip 451 can be clamped in the clamping groove 452, thereby facilitating the stability of the installation of the first hot melt block 41.

[0057] In the specific structure, the driving member 453 can adopt a gear well known to those skilled in the art, which is in mesh with the rack segment on the clamping strip 451, and the clamping strip 451 is arranged along the width direction of the chassis 1. In the specific implementation, the driving member 453 is driven to rotate, and through the meshing between the driving member 453 and the rack segment on the clamping strip 451, the clamping strip 451 can be caused to slide to be clamped in the clamping groove 452.

[0058] In addition, as a preferred implementation form, the mounting plate 44 is hollow, and a heating device is arranged in the cavity of the mounting plate 44, which can heat the first hot melt block 41. The hollow mounting plate 44 facilitates the installation of the heating device, and the heating device can heat the first hot melt block 41 to improve the temperature of the first hot melt block 41, so that the packaging materials are better hot-melted together, the packaging quality is improved, and the problem of loose packaging is avoided.

[0059] It is worth mentioning that the heating device in the embodiment can adopt a heating product well known to those skilled in the art, such as a ceramic heating sheet or an aluminum casting heating plate. In addition, the second hot melt block 42 in the embodiment should also be provided with the above-mentioned heating device.

[0060] In addition, as a preferred implementation form, as shown in Figure 3 each group of second hot melt blocks 42 includes two second hot melt blocks 42 arranged at intervals along the height direction of the chassis 1, and each second hot melt block 42 is provided with a guide plate 421 close to one side of the first conveying belt 26, which is used for guiding the conveying of the packaging materials.

[0061] Here, by arranging the guide plate 421 on each second hot melt block 42, the packaging materials at the top and bottom of the self-heating bag 61 can be guided to contact each other, so that the second hot melt block 42 can heat seal the packaging materials.

[0062] It should be noted that the packaging material at the top of the self-heating bag 61 is the upper packaging material 62 in the following text, and the packaging material at the bottom of the self-heating bag 61 is the lower packaging material 63 in the following text. In the specific implementation, the guide plate 421 is gradually inclined downward along the conveying direction (i.e. from front to back as shown in Figure 1 the upper packaging material 62 and the lower packaging material 63 gradually approach and contact each other under the action of each guide plate 421, and then the upper packaging material 62 and the lower packaging material 63 are heat sealed together by the second hot melt block 42.

[0063] In addition, as a preferred implementation form, as shown in Figure 2As shown in the figure, the feeding mechanism 3 comprises a first raw material shaft 31 rotatably arranged on the first support 21 for conveying the lower layer packaging material 63, a second raw material shaft 32 rotatably arranged on the second support 22 for conveying the upper layer packaging material 62, a first waste material shaft 33 rotatably arranged on the third support 23 for recycling the residual lower layer packaging material 63, and a second waste material shaft 34 rotatably arranged on the third support 23 for recycling the residual upper layer packaging material 62. Of course, in other embodiments, the second raw material shaft 32 can also be rotatably arranged on the first support 21.

[0064] It can be understood that the feeding mechanism 3 is composed of the first raw material shaft 31, the second raw material shaft 32, the first waste material shaft 33 and the second waste material shaft 34. Through the arrangement of the first waste material shaft 33 and the second waste material shaft 34, the residual packaging material can be recycled, so as to facilitate the re-use of the residual packaging material in the production process, realize the recycling of resources, and further improve the economic benefits.

[0065] It should be noted that, as shown in Figure 1 and Figure 2 , the residual lower layer packaging material 63 wound on the first waste material shaft 33 and the residual upper layer packaging material 62 wound on the second waste material shaft 34 are only a part of the packaging material for the purpose of illustration, not the complete packaging material.

[0066] In the specific structure, one end of the lower layer packaging material 63 is wound on the first raw material shaft 31, the other end of the lower layer packaging material 63 passes through each group of second hot melt blocks 42 and is wound on the first waste material shaft 33, and the lower layer packaging material 63 is in contact with the first conveying belt and the second conveying belt 27. Similarly, one end of the upper layer packaging material 62 is wound on the second raw material shaft 32, and the other end of the upper layer packaging material 62 passes through each group of second hot melt blocks 42 and is wound on the second waste material shaft 34. At this time, the packaging device is not running, and the heating device will not heat the corresponding second hot melt block 42, so that the upper layer packaging material 62 and the lower layer packaging material 63 passing through each group of second hot melt blocks 42 will not be heat sealed together.

[0067] In specific implementation, the heat pack 61 is placed on the top of the lower layer packaging material 63, and then under the action of the first conveying belt 26 and the first waste material shaft 33, the heat pack 61 moves with the lower layer packaging material 63 to the second raw material shaft 32. At this time, under the action of the second waste material shaft 34, the upper layer packaging material 62, the heat pack 61 and the lower layer packaging material 63 move together to the packaging mechanism 4.

[0068] The upper layer packaging material 62 and the lower layer packaging material 63 are guided by the guide plates 421, so that the two side edges of the upper layer packaging material 62 in the width direction are in contact with the two side edges of the lower layer packaging material 63 in the width direction, and the upper layer packaging material 62 and the lower layer packaging material 63 on both sides of the self-heating bag 61 in the width direction are heat sealed together by the second hot melt blocks 42 after the second hot melt blocks 42 are heated.

[0069] Meanwhile, the third motors 432 drive the corresponding drive shafts 43 to rotate in the counterclockwise direction, so that the two mounting plates 44 drive the corresponding first hot melt blocks 41 to move close to each other, so as to heat seal the upper layer packaging material 62 and the lower layer packaging material 63 on one side of the self-heating bag 61 in the length direction, and then the third motors 432 drive the corresponding drive shafts 43 to rotate in the clockwise direction, so that the two mounting plates 44 drive the corresponding second hot melt blocks 42 to move away from each other.

[0070] Secondly, after the upper layer packaging material 62 and the lower layer packaging material 63 on one side of the self-heating bag 61 in the length direction are heat sealed together, the upper layer packaging material 62, the self-heating bag 61 and the lower layer packaging material 63 are continuously conveyed by the first conveying belt 26, the second conveying belt 27, the first waste shaft 33 and the second waste shaft 34, and when the upper layer packaging material 62 and the lower layer packaging material 63 on the other side of the self-heating bag 61 in the length direction are not heat sealed, the above operation is repeated to heat seal the upper layer packaging material 62 and the lower layer packaging material 63 on the other side of the self-heating bag 61 in the length direction together to form a heat sealed bag, so that the packaging of the self-heating bag 61 can be completed.

[0071] In addition, in this embodiment, as a preferred implementation form, as shown in Figure 2 and Figure 6 The cutting mechanism 5 includes two cutting tools 51 rotatably arranged on the third support 23, and the two cutting tools 51 are arranged between the second conveying belt 27 and the first waste shaft 33 and are spaced apart in the height direction of the base frame 1.

[0072] Here, the cutting mechanism 5 is composed of two cutting tools 51, and the two cutting tools 51 are arranged between the second conveying belt 27 and the first waste shaft 33, so that the cutting tools 51 can cut the packaging material after heat sealing and forming, so that the self-heating bag 61 after packaging is separated from the residual packaging material, and the residual packaging material is recycled.

[0073] In specific implementation, the self-heating bag 61 after heat sealing is conveyed to the cutting mechanism 5 by the second conveying belt 27, the excess packaging material is cut by the two cutting tools 51, the self-heating bag 61 after packaging is separated from the residual packaging material, and the residual lower layer packaging material 63 and the residual upper layer packaging material 62 are recycled by the first waste shaft 33 and the second waste shaft 34, respectively.

[0074] Specifically, in this embodiment, as a preferred implementation form, as shown in Figure 6 Each cutting tool 51 comprises a mounting shaft 511 arranged along the width direction of the chassis 1, two first cutting heads 512 arranged on the mounting shaft 511 along the width direction of the chassis 1, and a second cutting head 513 arranged between the two first cutting heads 512, the two first cutting heads 512 are respectively used for cutting the packaging material on both sides of the self-heating bag 61 in the width direction, and the second cutting heads 513 on each mounting shaft 511 are abutted and can cut the packaging material on one side of the self-heating bag 61 in the length direction.

[0075] Here, the cutting mechanism 5 is composed of two cutting tools 51, and the two cutting tools 51 are arranged between the second conveying belt 27 and the first waste shaft 33, so that the cutting tools 51 can cut the heat-sealed packaging material, separate the self-heating bag 61 after packaging from the residual packaging material, and facilitate recycling of the residual packaging material.

[0076] Specifically, each mounting shaft 511 drives the two first cutting heads 512 and the second cutting head 513 to rotate, and when the two second cutting heads 513 are abutted, the upper and lower packaging materials 62 and 63 on one side of the self-heating bag 61 in the length direction can be cut.

[0077] It is worth mentioning that after the two second cutting heads 513 cut the upper and lower packaging materials 62 and 63 on one side of the self-heating bag 61 in the length direction, they continue to rotate to be abutted again, at which time the upper and lower packaging materials 62 and 63 on the other side of the self-heating bag 61 in the length direction can be cut.

[0078] It should be noted that each first cutting head 512 in this embodiment is an annular blade, and the first cutting heads 512 on the same side of each mounting shaft 511 are always in contact, so that the upper and lower packaging materials 62 and 63 on both sides of the self-heating bag 61 in the width direction can be cut.

[0079] In addition, in this embodiment, as a preferred implementation form, as shown in Figure 2 The first waste shaft 33 and the second waste shaft 34 are connected by the first transmission belt 35, and the two mounting shafts 511 are connected by the second transmission belt 52. By this arrangement, the first waste shaft 33 and the second waste shaft 34 are connected by the first transmission belt 35, which can realize synchronous rotation of the first waste shaft 33 and the second waste shaft 34, and at the same time, can reduce the number of motors used, facilitating cost reduction.

[0080] In particular implementation, the fourth motor 53 is connected to one of the installation shafts 511, and under the driving of the fourth motor 53, the two installation shafts 511 can be synchronously rotated by the second transmission belt 52, one of the installation shafts 511 rotates clockwise, and the other installation shaft 511 rotates counterclockwise.

[0081] In addition, the fifth motor 36 is connected to the first waste shaft 33 or the second waste shaft 34, and under the driving of the fifth motor 36, the first waste shaft 33 and the second waste shaft 34 can be synchronously rotated by the first transmission belt 35, so as to recycle the residual upper packaging structure and lower packaging structure.

[0082] In use, one end of the lower packaging material 63 is wound on the first raw material shaft 31, the other end of the lower packaging material 63 is wound on the first waste shaft 33 after passing through each group of second hot melt blocks 42, one end of the upper packaging material 62 is wound on the second raw material shaft 32, and the other end of the upper packaging material 62 is wound on the second waste shaft 34 after passing through each group of second hot melt blocks 42, and the self-heating bag 61 is placed on the top of the lower packaging material 63. At this time, the first motor 241 is driven to rotate the two first rotating shafts 24 to make the first conveying belt 26 move, and the fifth motor 36 and the second transmission belt 52 are driven to rotate the first waste shaft 33 and the second waste shaft 34 to respectively pull the upper packaging material 62 and the lower packaging material 63.

[0083] Secondly, the self-heating bag 61 is placed on the top of the lower packaging material 63, and under the action of the first conveying belt 26, the first waste shaft 33 and the second waste shaft 34, the upper packaging material 62, the self-heating bag 61 and the lower packaging material 63 are transported to the packaging mechanism 4. At this time, the upper packaging material 62 and the lower packaging material 63 on both sides of the self-heating bag 61 in the width direction are heat sealed together under the action of each group of second hot melt blocks 42.

[0084] Meanwhile, under the driving of each third motor 432, each driving shaft 43 rotates counterclockwise, so that each mounting plate 44 drives the corresponding first hot melt block 41 to slide to heat seal the upper packaging material 62 and the lower packaging material 63 on one side of the self-heating bag 61 in the length direction. After heat sealing, under the action of the first conveying belt 26, the first waste shaft 33 and the second waste shaft 34 and the second conveying belt 27, the self-heating bag 61 which has completed part of the packaging is conveyed, and the upper packaging material 62 and the lower packaging material 63 on the other side of the self-heating bag 61 in the length direction are moved to the first hot melt block 41. The above operation is repeated to heat seal the upper packaging material 62 and the lower packaging material 63 on the other side of the self-heating bag 61 in the length direction to form a heat sealed bag, so as to complete the packaging of the self-heating bag 61. Thus, it is not necessary for the staff to continuously put in the self-heating bag 61 for packaging, so that the packaging efficiency can be effectively improved to meet the needs of large-scale production.

[0085] Further, the heat-sealed self-heating pack 61 is conveyed to the cutting mechanism 5 by the second conveying belt 27, and the two cutting knives 51 are synchronously rotated by the fourth motor 53 and the first transmission belt 35, and the upper packaging material 62 and the lower packaging material 63 which are heat-sealed together on one side of the self-heating pack 61 are cut by the second cutting heads 513 on the cutting knives 51, and the two mounting shafts 511 continue to rotate, and the upper packaging material 62 and the lower packaging material 63 which are heat-sealed together on the other side of the self-heating pack 61 are cut when the two second cutting heads 513 are reconnected.

[0086] Further, the two first cutting heads 512 on one mounting shaft 511 are always in contact with the two first cutting heads 512 on the other mounting shaft 511, so that the upper packaging material 62 and the lower packaging material 63 which are heat-sealed together on both sides of the self-heating pack 61 can be cut.

[0087] It should be noted that the cutting position of the first cutting head 512 is away from the side of the heat-sealed position of the upper packaging material 62 and the lower packaging material 63 of the self-heating pack 61. After cutting, the first waste shaft 33 and the second waste shaft 34 are driven to rotate, so that the residual lower packaging material 63 and the upper packaging material 62 can be recycled, respectively.

[0088] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
