[0058] The following is a specific introduction to each mechanism of this packaging machine. It should be noted that there are multiple linear drive mechanisms in this packaging machine. As the name implies, a linear drive mechanism is a drive mechanism that can achieve linear motion, and there are various types of such drive mechanisms. The linear drive mechanism in this application can be any drive mechanism that can achieve linear motion. The following are several types of linear drive mechanisms:

[0059] Electric linear motor: A device that uses magnetic field force to move a working object in a straight line.

[0060] Pneumatic cylinder: A device that uses gas to apply pressure to a piston to achieve linear motion.

[0061] Screw pair transmission mechanism: Achieves linear motion through the mutual helical motion of a screw pair.

[0062] Ball screw transmission mechanism: Achieves linear motion through the ball-screw thread fit of the ballscrew.

[0063] Servo motor transmission mechanism: Achieves linear motion by controlling the rotor position change of a servo motor.

[0064] The linear drive mechanism in this application is preferably a servo motor transmission mechanism, aiming at that the servo motor transmission mechanism is suitable for linear drive occasions with high precision and high speed motion.

[0065] In one specific embodiment, as Figure 3 shown, the conveying mechanism 11 includes a first conveyor belt 111 erected on the frame 10 and a pallet 112 that can be slidably installed on the first conveyor belt 111 for carrying products.

[0066] More specifically, the first conveyor belt 111 is a conveyor belt with a drive source, and the drive source can be a servo motor or a general motor, while the pallet 112 is a plate body capable of carrying products.

[0067] In one specific embodiment, as Figure 4 shown, the pusher mechanism 20 includes a first linear drive mechanism 21, a first sliding seat 22 slidably mounted on the first linear drive mechanism 21, and a push rod 23 mounted on the first sliding seat 22. After the product is placed on the first conveyor belt 111, the push rod 23 pushes the product into the next process.

[0068] In one specific embodiment, as Figures 5-6 shown, the transfer assembly 30 includes a first base 31, a chute 32 formed in the first base 31, and a guide plate 33 slidably mounted inside the chute 32; the transverse movement assembly 40 includes a second linear drive mechanism 41, a third linear drive mechanism 42 mounted on the second linear drive mechanism 41, a connecting frame 43 slidably mounted on the connecting frame 43, a first cylinder 44 mounted on the connecting frame 43, and a pressing block 45 fixed to the piston rod of the first cylinder 44.

[0069] It is worth mentioning that the transfer assembly 30 and the transverse movement assembly 40 cooperate with each other and can adapt to products of various sizes.

[0070] In one specific embodiment, as Figure 7 and Figure 8 shown, the edge-sealing and melting-cutting assembly 50 includes a fourth linear drive mechanism 51, a first connecting plate 52 mounted on the fourth linear drive mechanism 51, a heat-insulating plate 53 mounted on the first connecting plate 52, a guard plate 54, a first cutting knife 56 mounted on the heat-insulating plate 53, and a pressing plate 55 mounted on the guard plate 54;

[0071] The stretching assembly 80 includes a second base 81, a sixth linear drive mechanism 82 mounted on one side of the second base 81 on the frame 10, a seventh linear drive mechanism 83 mounted on the sixth linear drive mechanism 82, and a first pressing member 84 and a second pressing member 85 mounted on the seventh linear drive mechanism 83 for pressing the product.

[0072] As Figure 9 shown, the loading assembly 70 includes two oppositely arranged fixed seats 71 fixed on the frame 10 and two guide rollers 72 fixed on the two fixed seats 71, which provide a basis for the stretching assembly 80 to stretch the coating film.

[0073] As Figure 10As shown, the material blocking assembly 60 includes a fifth linear drive mechanism 61 and a baffle 62 mounted on the fifth linear drive mechanism 61 and capable of moving up and down. The baffle 62 can block the product from entering the next process, and after the product is melted and cut by the edge sealing and melting and cutting assembly, it cancels the obstruction of the product position, and the product enters the next process.

[0074] As Figure 11 and Figure 12 shown, the four-sided melting and cutting assembly 90 includes two oppositely arranged drive modules 91, two connecting seats 92 mounted on the drive modules 91, a second cutting knife 93, a leveling rod 94 and a second cylinder 95;

[0075] Among them, the drive module 91 includes a bidirectional linear drive mechanism 911, a support plate 912 and a second connecting plate 914 mounted on the bidirectional linear drive mechanism 911, and a sliding seat 913 that provides sliding support for the bidirectional linear drive mechanism 911.

[0076] There are four connecting seats 92 on the two oppositely arranged drive modules 91. Cooperating with the leveling rod 94 and the second cutting knife 93 mounted on the four connecting seats 92, the four corners of the product after preliminary edge sealing can be secondarily edge sealed, and the coated film after edge sealing is more flat. The second cylinder 95 serves as the driving source. In this process, the four-sided melting and cutting assembly 90 seals the edges of the product on the second conveyor belt 12. After the edge sealing is completed, the product leaves the packaging machine through the second conveyor belt 12.

[0077] The working process and beneficial effects of the present utility model are as follows:

[0078] First, the product to be packaged is placed on the pallet 112 on the conveying mechanism 11. At this time, the push rod 23 of the material discharging mechanism 20 pushes the product onto the guide plate 33 of the transfer assembly 30. Under the action of the transverse movement assembly 40, the product moves to the next process. At this time, the coated film on the guide roller 72 of the feeding assembly 70 is stretched by the stretching assembly 80 and covered on the product. The edge sealing and melting and cutting assembly 50 melts and cuts the covered coated film. The coated film covers the product, and the material blocking assembly 60 cancels the restriction on the product position. Finally, the four-sided melting and cutting assembly 90 completes the secondary edge sealing of the product. Finally, the product with the coated film is conveyed away from the packaging machine through the second conveyor belt 12, realizing the whole-process mechanized production from product conveying, packaging film covering to edge sealing and melting and cutting, reducing manual intervention, improving production efficiency, and reducing labor costs.

[0079] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
