[0048] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0050] like Figure 1-2As shown, the moist snuff packaging machine provided in this embodiment includes a frame 100, and a feeding assembly 200 is provided on the top of the frame 100. The discharge port of the feeding assembly 200 is connected to the inlet of the feeding tube 110 provided in the frame 100 through a pipe. A film feeding assembly 400 for providing packaging film is also provided on the top of the frame 100, and a forming block 120 is provided on the outer sleeve of the feeding tube 110 to wrap it. The packaging film provided by the film feeding assembly 400 is pre-folded into a shape for packaging materials through a forming groove 121 in the forming block 120, and a gap is provided between the inner peripheral wall of the forming groove 121 and the outer peripheral wall of the feeding tube 110 for the packaging film to pass through.

[0051] The frame 100 further includes a longitudinal sealing assembly 500, a transverse sealing assembly 600, and a clamping assembly 700, which are sequentially arranged from the top to the bottom of the packaging tube. The sealing end of the longitudinal sealing assembly 500 corresponds to the forming block 120. The outer wall of the forming block 120 corresponding to the longitudinal sealing assembly 500 is open and communicates with the forming groove 121, so that the sealing end of the longitudinal sealing assembly 500 can move in a first direction of the frame 100, approaching and contacting the packaging film to perform longitudinal edge sealing on the packaging film.

[0052] The transverse sealing assembly 600 can move as a whole in the second direction of the frame 100 toward or away from the longitudinal sealing assembly 500, and the sealing end of the transverse sealing assembly 600 can move toward or away from the feed pipe 110 in the first direction of the frame 100, so as to perform transverse edge sealing and cutting of the packaging film.

[0053] There is also a clamping assembly 700 below the transverse sealing assembly 600. The clamping assembly 700 is used to clamp the bottom end of the packaging film so that the packaging film remains stable during the processes of longitudinal edge sealing, transverse edge sealing and cutting.

[0054] A controller 190 is also provided on the frame 100 . The controller 190 is electrically connected to the feeding assembly 200 , the film feeding assembly 400 , the longitudinal sealing assembly 500 , the transverse sealing assembly 600 and the clamping assembly 700 , respectively, for realizing automatic control of the moist snuff packaging machine.

[0055] Combined here Figure 3-4 As shown, the feeding assembly 200 includes a frame 210 arranged on the top of the frame 100, a receiving plate 230 is provided on the top of the frame 210, a vibration motor 240 is provided on the bottom, a hopper 220 is provided on the top of the receiving plate 230, the discharge port of the hopper 220 is connected to the movable groove 231 opened on the receiving plate 230, and an air inlet 232 connected to the movable groove 231 is opened on the top of the receiving plate 230, and an air outlet 233 connected to the movable groove 231 is opened on the bottom plate.

[0056] It also includes a material transfer assembly 300 arranged on the top of the frame 210, and the material transfer assembly 300 includes a transfer cylinder 310 fixed on the top of the frame 210. The transfer cylinder 310 adopts the cylinder in the prior art, and a transfer plate 320 is connected to the piston of the transfer cylinder 310. The transfer plate 320 is embedded in the movable groove 231 and moves back and forth in the movable groove 231 under the drive of the transfer cylinder 310, and the movable groove 231 is extended along the third direction of the frame 100.

[0057] The transfer plate 320 is provided with a transfer groove 321 which runs through the transfer plate 320. During actual use, the vibration motor 240 operates to make the frame 210 and the receiving plate 230 vibrate synchronously. At this time, the transfer plate 320 is moved to the transfer groove 321 under the drive of the transfer cylinder 310 to connect to the discharge port of the hopper 220. The material in the hopper 220 enters the transfer groove 321 under the action of vibration, and will not leave the transfer groove 321 due to the obstruction of the bottom groove wall of the movable groove 231. Subsequently, the transfer plate 320 is driven by the transfer cylinder 310 to a position connected to the air outlet 233, and the air inlet 232 blows air into the transfer groove 321 through an air supply source connected to the pipe, so that the material enters the air outlet 233 under the action of blowing or the synchronous action of blowing and vibration, and enters the feeding pipe 110 through the pipe connected to the air outlet 233 and the feeding pipe 110.

[0058] Combined here Figure 5 As shown, the film feeding assembly 400 includes a fixed frame 410 fixed to the frame 100. At least one film supply roller 420 is disposed on top of the fixed frame 410. A film supply roll for providing packaging film is mounted on the film supply roller 420. The fixed frame 410 is also provided with several film feeding rollers 430. A film feeding motor 440 is also provided on the fixed frame 410. The film feeding motor 440 is in driving connection with one of the film feeding rollers 430. In actual use, the packaging film on the film roll is pre-wound around the several film feeding rollers 430 in sequence, then passes through the forming groove 121 of the forming block 120 and extends to the bottom of the feed pipe 110. After edge sealing by the longitudinal sealing assembly 500 and the transverse sealing assembly 600, the film is used to receive the material provided by the feed pipe 110.

[0059] An extension plate 450 is provided at the bottom of the fixing frame 410. A proximity switch 460, electrically connected to the film feed motor 440, is provided at the bottom of the extension plate 450. The proximity switch 460 is used to detect the distance between the packaging film and the film feed roller 430. In actual use, when the packaging film on the film feed assembly 400 is pulled away by the transverse sealing assembly 600, the packaging film is straightened, and the distance between the packaging film above the proximity switch 460 and the proximity switch 460 increases. The proximity switch 460 closes, and the film feed motor 440 starts feeding the packaging film, which reduces the distance between the packaging film above the proximity switch 460 and the proximity switch 460 again. The proximity switch 460 senses the packaging film and is disconnected, causing the film feed motor 440 to stop operating and cease film feeding.

[0060] Combined here Figure 6 As shown, the longitudinal sealing assembly 500 includes a first mounting plate 510, a second guide rod 520, a second edge sealing cylinder 530, a second movable block 540 and a heat sealing block 550. The first mounting plate 510 is arranged on the side wall of the frame 100, and the forming block 120 is provided on the top of the first mounting plate 510. The second guide rod 520 is laterally arranged on both sides of the first mounting plate 510. The second edge sealing cylinder 530 is provided on the mounting plate. The piston of the second edge sealing cylinder 530 is connected to the end of the second guide rod 520 through the second connecting plate 560. The other end of the second guide rod 520 is connected to the second movable block 540. The heat sealing block 550 is provided on the second movable block 540. The heat sealing block 550 is driven by the second edge sealing cylinder 530 to approach or move away from the forming block 120.

[0061] In actual use, the second edge sealing cylinder 530 drives the second movable block 540 to move in the first direction of the frame 100 close to the forming block 120, and uses the heat sealing block 550 on the second movable block 540 to contact the packaging film inside the forming groove 121 on the forming block 120 through the opening of the forming block 120, and longitudinally seals the packaging film folded on both sides, so that the packaging film forms a cylindrical structure.

[0062] The second edge sealing cylinder 530 is a pneumatic cylinder or a hydraulic cylinder in the prior art.

[0063] Combined here Figure 7As shown, in order to achieve continuous lowering of the packaging film and continuous snuff packaging, the transverse sealing assembly 600 needs to be moved in the second direction of the frame 100 to clamp the cylindrical packaging film and reset and pull it down. Specifically, two guide rods 140 arranged opposite to each other are provided inside the frame 100. A lifting plate 130 is mounted on the two guide rods 140. The transverse sealing assembly 600 is mounted on the lifting plate 130. A lifting motor 150, a first synchronous wheel 160, and a second synchronous wheel 170 are also provided inside the frame 100. The first synchronous wheel 160 and the second synchronous wheel 170 are connected by a transmission belt 180. The motor shaft of the lifting motor 150 is connected to the first synchronous wheel 160 or the second synchronous wheel 170 through a gearbox. The lifting plate 130 is provided with a transmission member 131 meshing with the transmission belt 180. The lifting plate 130 is driven by the lifting motor 150 to move in the axial direction of the guide rods 140.

[0064] In addition, the transverse sealing assembly 600 includes a first guide rod 610, a first edge sealing cylinder 620, a first movable block 640, an edge sealing blade 641 and an ultrasonic welder 650. The first guide rod 610 is horizontally mounted on both sides of the lifting plate 130. The first edge sealing cylinder 620 is arranged on the lifting plate 130, and the piston of the first edge sealing cylinder 620 is connected to the end of the first guide rod 610 through a first connecting plate 660. The other end of the first guide rod 610 is connected to the first movable block 640. The edge sealing blade 641 is provided on a side wall of the first movable block 640 facing the frame 100. The ultrasonic welder 650 is fixed on the lifting plate 130. The welding head of the ultrasonic welder 650 is the sealing end of the transverse sealing assembly 600. The first movable block 640 is driven by the first edge sealing cylinder 620 to approach or move away from the ultrasonic welder 650.

[0065] In actual use, the lifting motor 150 is operated to first move the entire transverse sealing assembly 600 closer to the longitudinal sealing assembly 500 in the second direction of the frame 100. The piston on the first edge sealing cylinder 620 of the transverse sealing assembly 600 is then extended and retracted, driving the first movable block 640 to move closer to the ultrasonic welder 650 disposed on the lifting plate 130 in the first direction of the frame 100. The two movable blocks cooperate to clamp the packaging film. After the lifting motor 150 is reset, the transverse sealing assembly 600 is driven to pull the packaging film downward.

[0066] After being pulled down into place, the high temperature of the ultrasonic welder 650 is used to achieve the transverse edge sealing of the packaging film, and the vibration of the ultrasonic welder 650 is used in conjunction with the edge sealing blade 641 to cut the packaging film.

[0067] The first edge sealing cylinder 620 is a pneumatic cylinder or a hydraulic cylinder in the prior art.

[0068] Combined here Figure 8 As shown, the clamping assembly 700 includes a second mounting plate 710, on which are provided two clamping cylinders 720 arranged opposite to each other, and a clamping plate 730 arranged on the pistons of the two clamping cylinders 720. The two clamping cylinders 720 approach or move away from each other in the first direction of the frame 100, so that the clamping area formed between the two clamping plates 730 becomes larger or smaller, clamping the bottom of the packaging film.

[0069] The clamping cylinder 720 is a pneumatic cylinder or a hydraulic cylinder in the prior art.

[0070] The working steps of the moist snuff packaging machine provided in this embodiment are as follows:

[0071] First, the packaging film is manually pre-wound around several film feed rollers 430 and passed through the forming groove 121 of the forming block 120 to be folded into a cylindrical shape. The longitudinal edges of the film are first sealed by the longitudinal sealing assembly 500. The bottom of the film is then stretched to the position where it is located by the transverse sealing assembly 600, where it is transversely sealed to ensure that snuff materials can be inserted for packaging.

[0072] Then, the vibration motor 240 and the transfer cylinder 310 are started, so that the material on the hopper 220 enters the feeding pipe 110 under the action of blowing alone or blowing and vibration at the same time and finally falls into the packaging film;

[0073] During this process, the longitudinal sealing assembly 500 continuously performs longitudinal edge sealing on the packaging film passing through the forming block 120;

[0074] Then, the transverse sealing assembly 600 is driven by the lifting motor 150 to lift and clamp the packaging film, and then reset to pull the packaging film down. After being pulled down to the right position, the ultrasonic welder 650 is used in conjunction with the edge sealing blade 641 to perform high-temperature vibration transverse edge sealing and cutting.

[0075] During this process, the clamping cylinder 720 drives the clamping plate 730 to clamp the bottom of the packaging film.
