[0038] Reference Figures 1 to 3, a longitudinal film sealing mechanism according to an embodiment of the first aspect of the present invention includes a bracket 100, a first positioning mechanism 200, a second positioning mechanism 300 and a film sealing assembly, the first positioning mechanism 200 is arranged on the bracket 100, the first positioning mechanism 200 has a first pressing channel 210, the second positioning mechanism 300 is spaced apart from the first positioning mechanism 200, the second positioning mechanism 300 has a second pressing channel 310, and there is a gap between the second pressing channel 310 and the first pressing channel 210, the first pressing channel 210 and the second pressing channel 310 form a film material conveying channel that can compress the packaging film, the film sealing assembly includes a driving device 400, a film sealing head 500 and a matching plate 600, the driving device 400 is connected to the bracket 100, the film sealing head 500 is transmission-connected to the driving device 400, the matching plate 600 and the film sealing head 500 are relatively distributed on both sides of the film material conveying channel, the film sealing head 500 has a long heating portion, the driving device 400 is connected to the bracket 100, the film sealing head 500 is transmission-connected to the driving device 400, the matching plate 600 and the film sealing head 500 are relatively distributed on both sides of the film material conveying channel, the film sealing head 500 has a long heating portion, the driving device The device 400 can drive the film sealing head 500 to pass through the gap between the first pressing channel 210 and the second pressing channel 310 and press it against the matching plate 600, so that the packaging film passing through the film material conveying channel can be pressed between the heating part and the matching plate 600, and the heating part can heat-seal the packaging film. When in use, the film material enters the first positioning mechanism 200 and the second positioning mechanism 300 for positioning, and is pressed and conveyed through the first pressing channel 210 and the second pressing channel 310 set at intervals, which can improve the film material positioning effect, and the heated film sealing head 500 is inserted into the gap between the two pressing channels and cooperates with the matching plate 600 to seal the film material through the long heating part, so that the heat sealing working surface is increased, which can improve the sealing effect. Since there are two pressing channels to press the film material on both sides of the film sealing head 500, the deviation of the film material can be reduced, the stability of the film sealing is improved, and the occurrence of leakage and film jamming can be reduced.

[0039] Specifically, the first positioning mechanism 200 is arranged above the second positioning mechanism 300, and there is a gap between the two. Similarly, the first pressing channel 210 is located above the second pressing channel 310. The two pressing channels are parallel, and there is also a gap between the first pressing channel 210 and the second pressing channel 310. The film material is transported under the pressure of the two pressing channels. The two pressing channels form a complete film material conveying channel. The film sealing head 500 is located on one side of the film material conveying channel. The film sealing head 500 moves linearly under the drive of the driving device 400. The driving device 400 can be a cylinder. The film sealing head 500 is connected to the output end of the cylinder. The cylinder drives the film sealing head 500 to insert into the two pressing channels. The gap between the channels is formed and the film material is pressed against the matching plate 600 which is arranged on the other side of the film material conveying channel. The film sealing head 500 has a long heating part, which can be heated by an external heat source. The long heating part on the film sealing head 500 is in contact with the matching plate 600. The film material is conveyed under the pressure of the two pressing channels, and the film material in the gap between the two pressing channels is pressed and heat-sealed by the film sealing head 500. When in use, the film material enters from the entrance of the film material conveying channel and is heat-sealed at the film sealing head 500. The film material can be heat-sealed while being conveyed, and the two pressing channels can ensure that the film material is not deviated during conveying, and the long heating part has a better heat sealing effect than the heating part with point contact or line contact.

[0040] Reference Figure 2 In some embodiments of the present invention, the first positioning mechanism 200 includes a first driving component 220, a first annular belt 230 and a second annular belt 240. The first annular belt 230 and the second annular belt 240 are respectively rotatably connected to the bracket 100, and a first clamping channel 210 is formed between the first annular belt 230 and the second annular belt 240. The second positioning mechanism 300 includes a third annular belt 320 and a fourth annular belt 330. The third annular belt 320 and the fourth annular belt 330 are respectively rotatably connected to the bracket 100, and a second clamping channel 310 is formed between the third annular belt 320 and the fourth annular belt 330. The first driving component 220 simultaneously drives the first annular belt 230 and the third annular belt 320 to rotate. By arranging the two groups of annular belts up and down, two conveying channels can be formed, and the annular belt is used for conveying, which has the advantages of simple structure and easy maintenance.

[0041] Specifically, the annular belt can be a belt, which is sleeved on a transmission wheel provided on the bracket 100. The first annular belt 230 is provided on one side of the second annular belt 240, and in a plane, the gap between the two groups of belts forms a first compression channel 210. Similarly, the third annular belt is provided on one side of the fourth annular belt 330, and in a plane, the gap between the two groups of belts forms a second compression channel 310. The first driving component 220 can be a driving motor, and the output end of the driving motor is connected to the transmission wheel. The first annular belt and the third annular belt are sleeved on the transmission wheel together, thereby driving the two groups of belts to rotate, and the second annular belt and the fourth annular belt serve as driven parts to play a role of pressure. The film material can be transported under the pressure of the first compression channel 210 and the second compression channel 310, and the belt surface is relatively flat and will not damage the film material. At the same time, the belt case structure is simple and easy to maintain.

[0042] It should be noted that the endless belt is not limited to the above embodiment, and other embodiments may also be adopted. For example, the endless belt may also be a chain belt.

[0043] Reference Figure 2 In some embodiments of the present invention, the film sealing head 500 is located on the side close to the film material input direction of the film material conveying channel, so the film material is heated and sealed in the front half of the film material conveying channel, and is naturally cooled in the back half of the film material conveying channel after sealing. In addition, the two pressing channels can press and shape the film material, which can further improve the heat sealing effect.

[0044] Reference Figure 3 In some embodiments of the present invention, a matching groove 610 that matches the film sealing head 500 is provided on the matching plate 600. The matching groove 610 matches the shape of the elongated heating portion, and the elongated heating portion can be inserted into the matching groove 610. In a specific implementation, the film material is pressed by two sets of pressing channels, and the film sealing head 500 is inserted into the film material conveying channel and inserted into the matching groove 610 through the film material conveying channel. Therefore, the film material can be pressed into the matching groove 610, thereby further improving the pressing force and achieving a better heat sealing effect. At the same time, the excess waste film can be squeezed and cut off by the matching groove 610, and the cut end is more neat.

[0045] Reference Figures 1 to 3In some embodiments of the present invention, the bracket 100 includes a first base 110, a second base 120 and a third base 130. The second base 120 is fixedly connected to the first base 110, and the first annular belt 230 and the third annular belt 320 are arranged on the second base 120. The third base 130 is connected to the first base 110 through a sliding pair, and the second annular belt 240 and the fourth annular belt 330 are arranged on the third base 130. A driving component 112 is also provided on the first base 110. The driving component 112 is connected to the third base 130. The driving component 112 is used to drive the third base 130 to move closer to or away from the second base 120. The driving component 112 can drive the second annular belt 240 and the fourth annular belt 330 on the third base 130 to leave the first annular belt 230 and the third annular belt 320, thereby opening the film material conveying channel. If a fault occurs during production, it can be opened for maintenance, and debugging becomes more convenient.

[0046] Specifically, the first base 110 serves as a basic frame, the second base 120 is fixedly connected to the first base 110 by fasteners, a transmission wheel is connected to the first base 110, the first annular belt 230 and the third annular belt 320 are sleeved on the transmission wheel on the first base 110, and a slider 131 is provided on the third base 130, and a slide rail 111 is provided on the first base 110. The slider 131 of the third base 130 slides with the slide rail 111, and the third base 130 is also provided There is a transmission wheel, and the second annular belt 240 and the fourth annular belt 330 are sleeved on the transmission wheel. The driving component 112 on the first base 110 drives the third base 130 to slide along the slide rail 111, so that the third base 130 can be close to or away from the second base 120. During the production or debugging process, the driving component 112 drives the third base 130 to slide along the slide rail 111 away from the second base 120, so that the film material conveying channel can be opened for maintenance, which makes debugging more convenient.

[0047] It should be noted that the sliding pair is not limited to the above embodiment, and other embodiments may also be adopted. For example, the third base 130 may also be provided with a sliding groove, and the first base 110 may also be provided with a slider 131, and the sliding groove and the slider 131 slide together.

[0048] Reference Figures 1 to 3In some embodiments of the present invention, the driving assembly 112 includes a connecting shaft 113, a turntable 114 and a handle 115. The two ends of the connecting shaft 113 are rotatably connected to the third base 130 and the turntable 114 respectively. The turntable 114 is rotatably connected to the first base 110. The handle 115 is arranged on the circumference of the turntable 114. By pulling the handle 115, the turntable 114 can be rotated to pull the connecting shaft 113. The connecting shaft 113 pulls the third base 130 so that the third base 130 can be away from the second base 120. Similarly, pulling the handle 115 in the opposite direction can reset it. The connecting shaft 113 pushes the third base 130 to make it close to the second base 120, which is easy to operate.

[0049] Specifically, the handle 115 is connected to a point on the circumference of the turntable 114, so pulling or pushing the handle 115 can rotate the turntable 114, and the two ends of the connecting shaft 113 are respectively hinged to the turntable 114 and the third base 130, so the connecting shaft 113 can push or pull toward the third base 130 while the turntable 114 rotates, which is equivalent to the crank slider 131 mechanism. During use, if the mechanism fails, the third base 130 can be pulled by the handle 115 to open the film material delivery channel, which can facilitate the processing of components in the film material channel or the cleaning of the film material, and the operation is very convenient.

[0050] Reference Figures 4 to 6 A film sealing machine according to the second aspect of the present invention includes a longitudinal film sealing mechanism according to the first aspect of the present invention. By adopting the longitudinal film sealing mechanism, the film sealing effect can be improved when the film sealing machine performs longitudinal film sealing, the stability of the film sealing can be improved, and the occurrence of film deviation, sealing leakage, film jamming, etc. can be reduced.

[0051] Reference Figures 4 to 5In some embodiments of the present invention, the film sealing machine further includes a frame 700 and a transverse sealing mechanism 800. The transverse sealing mechanism 800 includes a second driving component 810, a first rotating shaft 840 and a second rotating shaft 850. The second driving component 810 is connected to the frame 700. The first rotating shaft 840 and the second rotating shaft 850 are respectively connected to the second driving component 810 in a transmission manner. An upper sealing plate 820 is provided on the first rotating shaft 840. The upper sealing plate 820 extends in a radial direction of the first rotating shaft 840. A lower sealing plate 830 is provided on the second rotating shaft 850. The lower sealing plate 830 extends in a radial direction of the second rotating shaft 850. Plate 820 is provided with a heating component, and the film material output by the longitudinal film sealing mechanism passes between the upper sealing plate 820 and the lower sealing plate 830, and the second driving component 810 drives the upper sealing plate 820 and the lower sealing plate 830 to rotate toward each other. The upper sealing plate 820 and the lower sealing plate 830 can rotate toward each other until they abut against each other to heat-seal and cut the film material. Through the transverse sealing mechanism 800, the cylindrical film after the longitudinal sealing film is completed can be cut into closed films, and then a heat shrinking step is performed to complete the film sealing. At the same time, the upper sealing plate 820 and the lower sealing plate 830 rotating toward each other can increase the film sealing speed compared with the existing upper and lower sealing plates.

[0052] Specifically, the second driving component 810 can be a driving motor and a transmission gear. The output end of the driving motor is connected to the transmission gear, and another transmission gear is engaged with it for transmission. One gear is connected to the first rotating shaft 840, and the other gear is connected to the second rotating shaft 850. Therefore, the first rotating shaft 840 and the second rotating shaft 850 rotate in opposite directions. The heating component on the upper sealing plate 820 is heated by an external heating source. The upper sealing plate 820 is fixedly connected to the first rotating shaft 840, so the upper sealing plate 820 rotates with the first rotating shaft 840, and the lower sealing plate 830 is fixedly connected to the second rotating shaft 850. Therefore, the lower sealing plate 830 rotates with the second rotating shaft 850. The upper sealing plate 820 and the lower sealing plate When 830 rotates to vertical, the end of the upper sealing plate 820 away from the first rotating shaft 840 and the end of the lower sealing plate 830 away from the second rotating shaft 850 can cooperate with each other, and the rotation direction of the upper sealing plate 820 and the lower sealing plate 830 is the direction of film material transportation. After horizontal sealing, the film material can be transported for a distance. When the upper sealing plate 820 and the lower sealing plate 830 rotate one circle, they can be re-matched to seal the film material horizontally again. Therefore, the film material is separated into sections of sealed packaging film, and the product inside is completely wrapped by the film material. The film is collected in the subsequent heat shrinkage process to complete the packaging. Adjusting the rotation speed of the upper sealing plate 820 and the lower sealing plate 830 and matching the speed of the conveyor belt can increase the production speed.

[0053] It should be noted that the heating component is not limited to the above embodiment, and other embodiments may also be adopted. For example, the heating component may also be provided on the lower sealing plate 830, or both the upper sealing plate 820 and the lower sealing plate 830 may be provided with heating components.

[0054] Reference Figures 4 to 5 In some embodiments of the present invention, the heating component is provided on the upper sealing plate 820, and at least one heat insulating rod 860 is provided on both sides of the upper sealing plate 820. The heat insulating rod 860 is connected to the first rotating shaft 840. There is a gap between the heat insulating rod 860 and the upper sealing plate 820. The two ends of the heat insulating rod 860 are connected to the first rotating shaft 840 through the connecting piece 913. Therefore, the heat insulating rod 860 and the upper sealing plate 820 rotate at the same time. When the upper sealing plate 820 is rotating, the rotating upper sealing plate 820 is about to rotate to the mating position. When the film is in the upper and lower sealing plates 820 and 830 positions, the heat-insulating rod 860 first contacts the film material, separating the film material from the upper sealing plate 820 and the lower sealing plate 830, and then sealing the film. After the film sealing is completed, the heat-insulating plate on the other side separates the film material from the upper and lower sealing plates 820 and 830. Because the temperature of the upper and lower sealing plates 820 and 830 is very high, if there is no heat-insulating rod 860, the film material will stick to the side of the upper and lower sealing plates 820 and 830, resulting in a decrease in the quality of the film sealing. The film sealing quality can be improved by setting the heat-insulating rod 860.

[0055] It should be noted that the arrangement of the insulation rod 860 is not limited to the above-mentioned embodiment, and other embodiments may also be adopted. For example, the insulation rod 860 may also be arranged on both sides of the lower sealing plate 830 and connected to the second rotating shaft 850, or insulation rods 860 may be arranged on both sides of the upper sealing plate 820 and the lower sealing plate 830, and the insulation plates may be connected to the first rotating shaft 840 and the second rotating shaft 850 respectively.

The linear drive mechanism on the film sorting mechanism 910 includes a third drive component 911, a screw 912 and a connecting piece 913. The third drive component 911 can be a motor, and the screw 912 is connected to the motor in a transmission manner.
