[0052] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0053] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0054] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0055] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0056] As Figures 2 to 11 shown, the embodiment of the present invention provides a bone bag packaging machine, including: a film feeding mechanism 1 for feeding a double-layer film 6 with convex bone strips 61 and concave bone strips 62; a feeding part 2 which includes a feeding cylinder 21, a feeding channel (not shown in the figure) is arranged in the feeding cylinder 21, one end of the feeding channel is a feeding inlet 22, the other end of the feeding channel is a feeding outlet 23, at the position where the double-layer film 6 is fed vertically from top to bottom, the feeding cylinder 21 is obliquely inserted into the double-layer film 6, and the feeding outlet 23 is located inside the double-layer film. It should be noted that the articles to be packaged conveyed by the feeding part 2 in the embodiment of the present invention are granular articles; a sealing mechanism 3 is arranged below the feeding outlet 23 of the feeding part 2 for sealing the bag mouth; a heat sealing mechanism 4 is arranged below the sealing mechanism 3 for heat sealing and cutting the side edges of the film.

[0057] An embodiment of the present invention provides a bone bag packaging machine. The film feeding part is used to convey a double-layer film 6 with convex bone strips 61 and concave bone strips 62. During the film feeding process, the feeding part 2 conveys the items to be packaged into the double-layer film 6. After the feeding is completed, the double-layer film 6 continues to move. The sealing mechanism 3 causes the convex bone strip 61 to be stuck into the concave bone strip 62. The double-layer film 6 continues to be conveyed, and the heat sealing mechanism 4 will complete the cutting and heat sealing of the side of the packaging bag. The cutting and heat sealing will cause one side of the current bone bag to be heat sealed and one side of the next bone bag to be heat sealed. At the same time as the heat sealing is completed, the bag making is completed and the entire packaging process is completed. By setting the feeding part 2 in the embodiment of the present invention, the feeding cylinder 21 is obliquely inserted into the double-layer film 6 with convex bone strips 61 and concave bone strips 62, and the items to be packaged are conveyed into the double-layer film 6 during the film feeding process. The packaging is completed while the bag is being made. Compared with the prior art where the bag is made first and then the packaging is carried out, the step of opening the bag is omitted. At the same time as the bag making is completed, the packaging of the items is also completed. The structure is simple and the packaging efficiency is high.

[0058] As Figures 2 to 5 shown, the film feeding mechanism 1 includes a frame 11, and a feeding disk 12, a film pulling part 13, a first film feeding part 14 and a second film feeding part 15 are arranged on the frame 11. Figure 2 FIG. is a schematic structural diagram of the double-layer film 6. The double-layer film 6 is wound around the feeding disk 12. The feeding disk 12 is rotatably connected to the frame 11. The feeding part 2 and the sealing mechanism 3 are arranged on the second film feeding part 15. The film is wound around the feeding disk 12 and sequentially passes around the film pulling part 13, the first film feeding part 14 and the second film feeding part 15. The film pulling part 13 includes two film pulling support plates 131. A film pulling driving roller 132 and a film pulling driven roller 133 are rotatably arranged between the two film pulling support plates 131. A film pulling driving assembly 134 is arranged on one of the film pulling support plates 131. The output end of the film pulling driving assembly 134 is connected to the film pulling driving roller 132. The film pulling driving assembly 134 drives the film pulling driving roller 132 to keep rotating continuously. The first film feeding part 14 includes two first film feeding support plates 141 and two second film feeding support plates 142. N groups of first film feeding fixed rollers 143 are rotatably arranged on the two first film feeding support plates 141. Swing plates 144 are respectively rotatably arranged on the two first film feeding support plates 141. M groups of first film feeding swing rollers 145 are rotatably arranged between the two swing plates 144, and m = n - 1. The film crosses and passes around the first film feeding fixed rollers 143 and the first film feeding swing rollers 145. A first buffer pad 1411 is arranged below the first film feeding support plate 141, and a second buffer pad 1421 is arranged on the second film feeding support plate 142. When the swing plates 144 swing, they will respectively collide with the first buffer pad 1411 and the second buffer pad 1421, and the first buffer pad 1411 and the second buffer pad 1421 buffer the collision force.

[0059] In the embodiment of the present invention, the double-layer film 6 bypasses between the film-pulling driving roller 132 and the film-pulling driven roller 133. There are three groups of first film-feeding fixed rollers 143 and two groups of first film-feeding swinging rollers 145. After passing through the film-pulling driving roller 132, the double-layer film 6 sequentially crosses and bypasses the first film-feeding fixed rollers 143 and the first film-feeding swinging rollers 145. When the double-layer film 6 is heat-sealed, it stops for a while and then moves for a while. If the film-pulling driving roller 132 and the film-pulling driven roller 133 also stop for a while and then move for a while, when the feeding tray 12 conveys the double-layer film 6, due to the inertia, when it stops, the double-layer film 6 will stack under the film-pulling driving roller 132 and the film-pulling driven roller 133. When starting again, there will be wrinkled film being involved between the film-pulling driving roller 132 and the film-pulling driven roller 133, causing damage to the double-layer film 6. To solve this problem, in the embodiment of the present invention, the film-pulling driving roller 132 keeps rotating continuously. By setting multiple groups of first film-feeding fixed rollers 143 and first film-feeding swinging rollers 145, the conveying path of the film becomes longer. Since the first film-feeding swinging roller 145 is rotatably arranged on the swinging plate 144, when heat-sealing, when the film at the heat-sealing position stops, the film-pulling driving roller 132 keeps rotating. Since the film feeding of the film-pulling driving roller 132 does not stop, the first film-feeding swinging roller 145 swings downward under the action of gravity, so that the double-layer film 6 remains taut. When the heat-sealing mechanism 4 is not heat-sealing and continues to convey the double-layer film 6, the first film-feeding swinging roller 145 will be lifted by the pulling force of the second film-feeding part 15. During the whole film-feeding process, the second film-feeding part 15 starts and pauses for a while, while the film-pulling part 13 keeps conveying continuously, effectively preventing the damage of the film caused by the film stacking between the film-pulling driving roller 132 and the film-pulling driven roller 133.

[0060] As Figure 5 shown, a film-pulling fixed rod 135 is arranged between the two groups of film-pulling support plates 131. The film-pulling driving assembly 134 includes a film-pulling driving motor 1341. The output end of the film-pulling driving motor 1341 is provided with a film-pulling driving wheel (not shown in the figure). The film-pulling driving roller 132 is sleeved on the film-pulling driving rod 1321. The two sides of the film-pulling driving rod 1321 are rotatably connected to the film-pulling support plates 131. One end of the film-pulling driving rod 1321 is coaxially provided with a film-pulling driven wheel 1322. A film-pulling belt 1343 is sleeved between the film-pulling driving wheel and the film-pulling driven wheel 1322. Specifically, in this embodiment, the film-pulling driving motor 1341 drives the film-pulling driving wheel to rotate. The film-pulling driving wheel drives the film-pulling driven wheel 1322 to rotate through the film-pulling belt 1343. The film-pulling driven wheel 1322 drives the film-pulling driving rod 1321 to rotate, so that the film-pulling driving roller 132 rotates to pull the film.

[0061] As Figure 5As shown, in order to make the film pulling driven roller 133 close to the film pulling driving roller 132 so that the double-layer film 6 can be conveyed between the film pulling driving roller 132 and the film pulling driven roller 133, opposite film pulling sliding grooves 1311 are formed on the two film pulling support plates 131. The film pulling driven roller 133 is sleeved on the film pulling driven rod 1331. Both sides of the film pulling driven rod 1331 can slide on the film pulling sliding grooves 1311. Film pulling adjustment components 136 are arranged on both sides of the film pulling driven rod 1331. The film pulling adjustment component 136 includes a film pulling sliding seat 1361 and a film pulling fixed seat 1362. The film pulling sliding seat 1361 is connected to one end of the film pulling driven rod 1331. The film pulling fixed seat 1362 is arranged on the film pulling support plate 131. A film pulling linkage rod 1363 is arranged on the film pulling fixed seat 1362. The film pulling linkage rod 1363 extends obliquely towards the film pulling sliding seat 1361. The film pulling linkage rod 1363 and the film pulling sliding seat 1361 are connected by a film pulling elastic member 1364. Specifically, in the embodiment of the present invention, the film pulling driven rod 1331 and the film pulling linkage rod 1363 are connected by the film pulling elastic member 1364. The film pulling driven roller 133 has an elastic force towards the film pulling driving roller 132 as a pulling force, so that the film pulling driven roller 133 is tightly attached to the film pulling driven roller 133, effectively ensuring that the double-layer film 6 is conveyed between the film pulling driving roller 132 and the film pulling driven roller 133.

[0062] As Figure 3 、 4As shown in Figures 6, 7, and 8, the second film feeding part 15 includes two film feeding fixing plates 151. The first film feeding part 14 is connected to the film feeding fixing plates 151.

A heat-sealing groove 4103 is formed in the heat-sealing seat 4101. The heat-sealing knife 43 can pass through the heat-sealing groove 4103.

[0067] Specifically, in the embodiment of the present invention, the film feeding driving roller 153 continues to convey the double-layer film 6. After the double-layer film 6 passes through the sealing mechanism 3, it passes through the heat-sealing through groove 411. The heat-sealing driving motor 421 and the right-angle reduction gear 422 drive the two driving rods 423 to rotate. The driving rod 423 drives the first linkage plate 425 to rotate. The two ends of the first linkage plate 425 are respectively rotatably connected with a first connecting rod 426 and a second connecting rod 427. The second connecting rod 427 can drive the guiding sliding plate to reciprocally slide on the guiding rod 451. The first connecting rod 426 drives the guiding rod 451 to slide. The first connecting rod 426 drives the heat-sealing cutting seat 47 to move, so that the heat-sealing knife 43 and the heat-sealing cutting seat 451 approach or separate from each other synchronously. At the same time, the first connecting rod 426 keeps the two sides of the first linkage plate 425 balanced, effectively ensuring the stability of the second connecting rod 427 during swinging. The heat-insulating seat 491 is driven to slide by the guiding sliding plate 48. The heat-insulating seat 491 drives the heat-sealing knife 43 to act. The heat-sealing knife 43 approaches the heat-sealing cutting seat to complete cutting and heat-sealing. The heat-insulating seat 491 plays a role in heat insulation, preventing heat from being transferred to the heat-sealing driving motor 421 and affecting the stability of the heat-sealing driving motor 421. In the embodiment of the present invention, the first linkage plate 425, the first connecting rod 426 and the second connecting rod 427 are driven by the heat-sealing driving motor 421, and the guiding sliding plate 48 is driven by the second connecting rod 427 to form a lateral driving structure to drive the heat-sealing knife 43 to perform lateral heat-sealing on the side of the film.

A jaw cylinder 53 is provided on the separation mounting plate 521. The jaws of the jaw cylinder 53 are connected with a clamping plate 531. The clamping plate 531 is located below the heat-sealing through groove 411. Specifically, in the embodiment of the present invention, during the heat-sealing process, first, the heat-sealing seat 4101 is pressed against the heat-sealing cutting seat 44, and then the heat-sealing knife 43 passes through the heat-sealing groove 4103 of the heat-sealing cutting seat 44 for heat-sealing; when the heat-sealing is completed, the guiding sliding plate 48 retracts. During the retraction process, first, the heat-sealing knife 43 retracts. At this time, the heat-sealing seat 4101 still presses against the heat-sealing cutting seat 44, that is, the current packaging bag is still clamped by the heat-sealing seat 4101 and the heat-sealing cutting seat 44. At this time, the clamping plate 531 of the separation part 5 clamps the side of the previous heat-sealed packaging bag, and is driven to move downward by the separation driving cylinder 52, so that the previous completed packaging bag is completely separated from the current packaging bag, and at the same time, the normal conveyance of the film before heat-sealing will not be affected.
