[0044] Referring to Figures 1 to 3 As shown in the drawings, the first aspect of the present application proposes a lower die cutting mechanism, comprising: a conveying line 100, a rack 200, a pair of roller assemblies 300, an inclined piece 400 and a cutting assembly 500.

[0045] The conveying line 100 has a first covering port 101.

[0046] Specifically, the conveying line 100 has a conveying surface for conveying the products, and the conveying surface has a first covering opening 101, and a portion of the packaging film will be inserted into the first covering opening 101, so that the middle part of the packaging film is aligned with one side of the product, and when the product is conveyed on the conveying surface, the one side of the product will press the packaging film, and then the bottom surface of the product will be automatically covered with the packaging film, and at the same time, the top surface of the product will also be covered with the packaging film, and in the subsequent processing process, the packaging film outside the product will be sealed by hot pressing, so as to realize the packaging of the product.

[0047] The rack 200 is arranged on the conveying line 100.

[0048] Specifically, the rack 200 is arranged on the conveying line 100 and is directly placed on the ground, the rack 200 forms a fixed carrier and installs and fixes other structures. In the embodiment, the rack 200 includes two opposite base plates and two opposite cross beams respectively connected to two ends of the two base plates, and a rectangular frame is formed between the cross beams and the base plates.

[0049] The roller assembly 300 is arranged on the rack 200 and is used for clamping the packaging film, and the roller assembly 300 has a conveying opening.

[0050] Specifically, the roller assembly 300 is arranged in the rectangular frame of the rack 200, and the roller assembly 300 clamps the packaging film through the clamping force formed between the two rollers to provide a certain tension to the packaging film, so that the packaging film remains flat, and at the same time, the conveying of the packaging film can be realized through the rolling of the packaging film itself.

[0051] The inclined piece 400 is used for receiving the packaging film of the conveying opening and has a cutting opening 401 and a discharging opening, and the discharging opening is used for conveying the packaging film to the first covering opening 101.

[0052] Specifically, the inclined piece 400 is an inclined flat plate, and the inclined piece 400 has a high end and a bottom end, the high end receives the packaging film of the conveying opening, and the bottom end is the discharging opening to discharge the packaging film, so as to realize the transportation of the packaging film. In addition, the inclined piece 400 is arranged in an inclined manner, so that the inclined piece 400 can accommodate longer packaging film without occupying the height space of the equipment, and the height space of the whole equipment can be effectively controlled to reduce the height of the equipment, thereby facilitating the installation and maintenance of the equipment. In the embodiment, the inclined piece 400 is connected to the rack 200 or is directly fixed on the ground.

[0053] The cutting assembly 500 is aligned with the cutting opening 401, and the cutting assembly 500 can fix the packaging film on the inclined piece 400 and cut the packaging film at the cutting opening 401.

[0054] Specifically, the cutting assembly 500 is aligned with the cutting opening 401, so that the cutting assembly 500 can fix the packaging film on the surface of the inclined piece 400 by abutting against the inclined piece 400, and then cut the packaging film, so that the packaging film is cut in a static state, and the cutting of the packaging film is more flat. In the embodiment, the cutting assembly 500 is fixed to the rack 200, or is separately fixed to the ground.

[0055] It is worth understanding that, by inclining the inclined piece 400, the packaging film is inclined and guided, so that the length of the packaging film in the vertical direction is reduced, so as to reduce the overall height of the equipment. At the same time, by fixing and cutting the packaging film on the inclined piece 400 by the cutting assembly 500, the packaging film is cut in a fixed state, so that the cut of the packaging film is more regular, and the yield of the packaging film when packaging the product is higher.

[0056] Referring to Figure 2 With Figure 3 As shown in the figure, in some specific embodiments of the utility model, the cutting assembly 500 includes a fixing piece 510 and a cutting piece 520, the fixing piece 510 and the cutting piece 520 are respectively arranged on both sides of the inclined piece 400, the direction along the direction towards the cutting piece 520 or away from the cutting piece 520 is defined as the cutting direction, and the fixing piece 510 can move along the cutting direction.

At the same time, because the fixing piece 510 fixes the packaging film, the packaging film will not be offset during the cutting process of the cutting piece 520, so that the cutting precision is higher. In addition, the cutting edge of the cutting piece 520 cuts the packaging film as a whole, and the whole cutting process is crisp and neat, so that the cut of the packaging film is more regular.

[0058] The external power source can be a mechanical structure with linear movement function such as a telescopic rod, a telescopic motor or a screw block structure. The fixing piece 510 is arranged above the inclined piece 400, and the cutting piece 520 is arranged below the inclined piece 400.

[0065] Specifically, the main plate body part 5111 is used for fixing the fixed plate part 512, and the cutting part 5112 is used for abutting and cutting the packaging film together with the cutting member 520. During movement of the main plate part 511 along the cutting direction, the two fixed plate parts 512 are respectively aligned with the inclined members 400 on both sides of the cutting opening 401, the cutting part 5112 is aligned with the cutting opening 401, the cutting part 5112 abuts against the elastic layer 600, and the elastic layer 600 is elastically deformed, so that the elastic layer 600 exposes the cutting edge of the cutting member 520, and then the cutting part 5112 can abut against the cutting edge of the cutting member 520 and cut the packaging film.

[0066] Referring to Figure 2 With Figure 3 As shown in the drawings, in some specific embodiments of the utility model, the cutting part 5112 has a cutting groove 5113 relative to the cutting surface of the inclined member 400, and the cutting groove 5113 is adapted to the cutting edge of the cutting member 520.
