[0025] The preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 5As shown, this embodiment provides a paper discharge knife structure, comprising: a paper discharge knife 1, a knife holder 2, a paper discharge knife rod 3, an adjustment handle 4, and a knife holder fixing assembly. The paper discharge knife 1 is mounted on the knife holder 2, and the knife holder 2 is mounted on the paper discharge knife rod 3 via the knife holder fixing assembly. The paper discharge knife rod 3 is also provided with an adjustment handle 4. The paper discharge knife 1 in this embodiment refers to a scraper structure used to separate packaging paper to assist in feeding packaging paper. The paper discharge knife 1 preferably adopts an arc-shaped paper discharge knife with an inwardly concave upper surface to better separate packaging paper. The paper discharge knife rod 3 refers to a rod-shaped structure for installation. The adjustment handle 4 refers to a handle structure that facilitates user adjustment operations. The knife holder fixing assembly refers to a structural component used to secure and release the knife holder 2. Here, the adjustment is for securing and releasing the knife holder 2. Since the paper discharge knife 1 is mounted on the knife holder 2, securing and releasing the knife holder 2 is equivalent to securing and releasing the paper discharge knife 1.

[0027] Therefore, this embodiment can facilitate the installation, clamping and loosening of the paper unloading knife structure. The overall structure is simple and efficient, which helps to improve the production efficiency of the packaging molding equipment and meet its processing needs. In actual use, since the paper unloading knife 1 needs to be against other parts of the equipment to separate the packaging paper, such as Figure 8 As shown, if the existing fixed structure is used when the paper unloading knife is not needed, it may cause unnecessary wear and tear on other parts of the device, thereby shortening the service life of the device. Unlike the existing technology, this embodiment allows the paper unloading knife structure to be adjusted. When the paper unloading knife 1 is not needed, it can be loosened and lowered, thereby extending the service life of the device.

[0028] More specifically, Figures 1 to 5 As shown, the knife seat fixing assembly of this embodiment includes a knife seat fixing ring 5, a knife seat spring piece 6, and a knife seat clamping block 7. The knife seat 2 and the knife seat fixing ring 5 are both connected to the paper unloading knife rod 3. The first end of the knife seat spring piece 6 is connected to the knife seat fixing ring 5, and the second end of the knife seat spring piece 6 is connected to the knife seat 2 through the knife seat clamping block 7. The knife seat fixing ring 5 of this embodiment is preferably mounted on the bottom of the knife seat 2, and then mounted on the paper unloading knife rod 3 together with the knife seat 2; the knife seat spring piece 6 is clamped by the limiting and fixing effect of the knife seat clamping block 7, so as to ensure the position of the paper unloading knife 1 and knife seat 2 during operation.

[0029] Preferably, Figures 3 to 5As shown, the second end of the tool holder spring piece 6 in this embodiment is an arc spring piece 601, and the tool holder clamping block 7 includes a mounting end 701 and a clamping end 702 connected to each other. The mounting end 701 is connected to the tool holder 2, and the position of the clamping end 702 corresponds to the position of the arc spring piece 601, so as to better achieve the clamping effect. Moreover, through the design of the arc spring piece 601, a certain buffering effect is also provided when the alarm is triggered, making the product more stable and reliable.

[0030] Preferably, Figures 3 to 5 As shown, the mounting end 701 of this embodiment is provided with an elliptical mounting hole. The design of the elliptical mounting hole enables the knife holder clamping block 7 to achieve a certain adjustable range, thereby meeting different molding processing requirements and improving the product's flexible application. The knife holder 2 of this embodiment is provided with at least two mounting holes 201, thereby better ensuring the installation and fixation of the paper unloading knife 1. The paper unloading knife 1 can be installed through different mounting holes 2012 according to different requirements, improving the adaptability of the product.

[0031] like Figures 1 to 3 As shown, this embodiment also includes a mounting seat 8 and a mounting plate 9, which are respectively arranged at the two ends of the paper unloading knife rod 3 to facilitate the installation requirements of the paper unloading knife structure. The adjustment handle 4 includes a handle locking block 401 and a handle connecting rod 402. The handle connecting rod 402 is detachably arranged on the paper unloading knife rod 3 through the handle locking block 401, thereby facilitating the setting of the adjustment handle 4. What is adjusted here is the rotation of the paper unloading knife rod 3, which in turn drives the overall movement of the paper unloading knife structure, such as changing its angle, or after removing the packaging box mold 1201, pulling the adjustment handle 4 to lower the paper unloading knife 1, etc. This embodiment uses the principle of leverage to save the force required when adjusting the paper unloading knife structure by pulling the handle connecting rod 402, thereby improving the rationality of the structural design.

[0032] It should be noted that the mounting base 8 of this embodiment is located adjacent to the handle lock block 401. The thickness of the mounting base 8 is greater than that of the mounting plate 9, allowing for adjustment via the adjustment handle 4 to lower the paper discharge knife structure and ensure the service life of the mounting base 8. The handle lock block 401 has a first opening slot 4011 at its bottom, with first fixing holes 4012 located on either side of its bottom. The mounting base 8 has a second opening slot 801 at its bottom, with second fixing holes 802 located on either side of its bottom. The paper discharge knife rod 3 is sleeved within the first and second opening slots 4011, 801. The design of the first and second opening slots 4011, 801 of this embodiment not only facilitates quick assembly with the paper discharge knife rod 3 but also provides a buffer space and force, making the adjustment process smoother and more reliable, and facilitating angle adjustment via the adjustment handle 4. The first fixing hole 4012 and the second fixing hole 802 can be locked by means of screws, nuts and other structures according to actual needs, so as to increase their fixing effect when necessary.

[0033] like Figures 6 to 8 As shown, this embodiment also provides a packaging forming device, including the paper unloading knife structure as described above, and includes a frame 10, a gluing machine 11 and a curling shaft assembly 12, the gluing machine 11 and the curling shaft assembly 12 are respectively arranged on the frame 10, the paper unloading knife rod 3 of the paper unloading knife structure is arranged in the gluing machine 11 through the mounting seat 8 and the mounting piece 9 at both ends, and is arranged on the side of the curling shaft assembly 12. More preferably, as Figure 8 As shown, the laminating machine 11 of this embodiment includes a laminating roller 1101, the crimping shaft assembly 12 includes a packaging box mold 1201, and the paper unloading knife 1 is arranged between the laminating roller 1101 and the packaging box mold 1201, so as to facilitate the separation and forming of the packaging paper after laminating, that is, the packaging paper is separated from the laminating roller 1101 and then transferred to the packaging box mounted on the packaging box mold 1201 for forming. The laminating roller 1101 refers to the roller structure in the laminating machine 11 for laminating, and the packaging box mold 1201 refers to the mold structure for mounting the packaging box that needs to be formed.

[0034] The specific implementation methods described above are preferred implementation methods of the present invention, and are not intended to limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to the specific implementation methods. All equivalent changes made in accordance with the shape and structure of the present invention are within the scope of protection of the present invention.
