[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Please see Figures 1 to 4 A packaging device with a protective structure includes a conveyor belt 1, a packaging component 2 fixedly installed on the side end of the conveyor belt 1, and a heat-melt sealing component 3 fixedly installed inside the packaging component 2.

[0030] The conveyor belt 1 includes a first frame 11, a feeding inclined plate 12 is fixedly installed inside the first frame 11, and three rotating rollers 13 are rotatably installed on the inner wall of the first frame 11. A sprocket 14 is fixedly installed at one end of two of the rotating rollers 13, and a chain 15 is sleeved on the outer surface of each sprocket 14.

[0031] The packaging assembly 2 includes a second frame 21 fixedly installed on the side of the first frame 11. A cover 22 is fixedly installed on the top of the second frame 21 by welding. A blower 23 is fixedly installed on the bottom of the cover 22. A main resistance wire heating strip 24 is fixedly installed on the bottom of the cover 22. A placement bracket 25 is fixedly installed on the inner wall of the second frame 21. The inner wall of the second frame 21 has through holes 26 and sliding grooves 27.

[0032] The hot melt encapsulation assembly 3 includes a first turntable 31 rotatably mounted on the inner wall of the through hole 26. A first handle 32 is rotatably mounted on the side end of the first turntable 31. The first turntable 31 and the first handle 32 constitute a rotating structure. Two first push rods 33 are sleeved on the outer surface of the first turntable 31.

[0033] In this embodiment, as Figure 2 As shown, a number of rotating rollers 13 form a transmission structure through sprockets 14 and chains 15. The outer surface of each rotating roller 13 is fitted with the same conveyor belt 16. A motor 17 is fixedly installed on the side end of the first frame 11 by welding. A bracket 18 is fixedly installed on the outer surface of the motor 17. A rotating roller 13 is rotatably installed on the side end of the motor 17.

[0034] In this embodiment, as Figure 3 As shown, a first guide roller 28 is rotatably mounted on the inner wall of the second frame 21, and a second guide roller 29 is fixedly mounted on one side of the inner wall of the second frame 21.

[0035] In this embodiment, as Figure 4 As shown, a buffer plate 34 is rotatably mounted on one end of each of the two first push rods 33, and the first turntable 31 and the buffer plate 34 form a crank-slider structure through the first push rods 33.

[0036] In this embodiment, as Figure 4As shown, the hot melt encapsulation assembly 3 also includes a second turntable 36 fixedly installed on the inner wall of the second frame 21. A second handle 35 is rotatably installed on the side end of the second turntable 36. The second handle 35 and the second turntable 36 form a rotating structure. A second push rod 37 is rotatably installed on the side end of the second turntable 36. A slide rod 38 is rotatably installed on one end of the second push rod 37. The slide rod 38 and the slide groove 27 form a sliding structure. The second turntable 36 and the slide rod 38 form a crank-slider structure through the second push rod 37. A secondary resistance wire heating strip 39 is fixedly installed at the bottom of the slide rod 38.

[0037] The working process of this packaging equipment with a protective structure is as follows:

[0038] First, the user needs to manually wrap the film around the outer surface of the second guide roller 29, and then it is conveyed to the inside of the placement bracket 25 through the first guide roller 28. Then, the user needs to pinch the two sides of the film to overlap each other. Then, the main resistance wire heating strip 24, which is fixedly installed at the bottom of the cover 22, will fuse the two sides of the packaging film together to form a plastic film ring. The blower 23, which is also fixedly installed at the bottom of the cover 22, will blow the film ring open to prevent the plastic film ring from sticking together. Then, the user can place the vegetables that need to be packaged on the top of the conveyor belt 16.

[0039] The motor 17, fixedly installed on the side of the first frame 11, is started by an external electrical control device. The motor 17 drives the rotating roller 13 to rotate, and the rotating roller 13 drives the sprocket 14 fixedly installed on the side of another rotating roller 13 to rotate together via a chain 15. The three rotating rollers 13 drive the conveyor belt 16 sleeved on the outer surface of the rotating rollers 13, thus transmitting the vegetables placed on top of the conveyor belt 16 into the device. When the vegetables are about to enter the device, the user needs to manually turn the first handle 32, which drives the first turntable 31 to rotate. The first push rod 33 sleeved on the outer surface of the first turntable 31 pushes the buffer plate 34 to flip, causing the buffer plate 34 to block the vegetables and prevent them from sliding out of the placement bracket 25 due to inertia. Before the vegetables enter the device, the user needs to manually turn the second handle 35, which drives the second turntable 36 to rotate. Step 6 will push the second push rod 37, which in turn will push the slide rod 38 and the auxiliary resistance wire heating strip 39 fixedly installed at the bottom of the slide rod 38 to move downwards together, thereby melting and sealing. After preparation, the vegetables are transported into the device. At the same time, because the buffer plate 34 is inside the placement bracket 25, the user only needs to turn the first handle 32 again to drive the first turntable 31 to rotate, thereby causing the buffer plate 34 to flip again. The vegetables inside the placement bracket 25 will also slide out of the placement bracket 25, and the film will continue to be transported. The main resistance wire heating strip 24 fixedly installed at the bottom of the cover 22 will seal the film. At the same time, the blower 23 will blow air into the film to prevent the film from closing. After the vegetables have completely left the placement bracket 25, the second handle 35 is turned by hand again, thereby driving the second turntable 36 and the second push rod 37, thereby driving the slide rod 38 to move downwards again, thereby sealing the sealing film.

[0040] Among them, the main resistance wire heating strip 24 and the auxiliary resistance wire heating strip 39 are both model JDR-100, while the hair dryer 23 is model KF-3153.
