Technical Field

[0001] This utility model relates to the field of winding and packaging technology of corrosion-resistant polycarbonate film, and in particular to a winding and packaging device for corrosion-resistant polycarbonate film. Background Technology

[0002] After the corrosion-resistant polycarbonate film is produced, it needs to be wound up using a winding machine.

[0003] For example, CN218401086U discloses a plastic film roll packaging machine. This technology includes a mounting plate with mounting grooves on both upper sides. A geared motor is fixedly connected to one side of one of the mounting grooves at the upper end of the mounting plate. A base plate is provided on the bottom surface of the mounting groove, and a weighing sensor is provided on the top center surface of the base plate. A weighing plate is provided on the top of the weighing sensor. However, the above technology still has problems in use due to structural limitations.

[0004] The above-mentioned technology uses a locking block to limit the winding roller, which requires manual disassembly during installation, making it quite troublesome. In addition, this technology uses a cutting disc to cut the plastic film, but a small section of the film is not corrected after cutting. Due to the characteristics of the film, it is easy for it to stick together, resulting in poor winding effect. Utility Model Content

[0005] The purpose of this invention is to solve the problems of troublesome installation of the roll core and easy adhesion in the existing plastic film roll packaging machine, and to propose a winding and packaging equipment for corrosion-resistant polycarbonate film.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 A winding and packaging device for corrosion-resistant polycarbonate film includes a winding table 1, a core 2 is provided in the winding table 1, winding mechanisms are provided on both sides of the core 2, and the core 2 rotates in the winding table 1 through the winding mechanisms. A top plate 5 is also installed in the winding table 1, and an ejection groove 19 is provided in the top plate 5. An electric hot knife 6 is provided in the ejection groove 19, and the electric hot knife 6 moves vertically in the ejection groove 19 through the ejection mechanism.

[0025] The hot knife 6 is slidably connected to the ejector groove 19. The hot knife 6 is equipped with a heating device inside. When the hot knife 6 comes into contact with the film, it can cut the film instantly to ensure the flatness of the cut.

[0026] The winding table 1 is also equipped with a rod support 3, a clamping rod 4 and a top plate 5. The rod support 3 is fixedly installed in the winding table 1. The two sets of clamping rods 4 are fixedly connected to the rod support 3 in an up-down sequence, and the clamping rods 4 are aligned with the core 2. The clamping rods 4 can prevent the film from contacting the winding table 1 during winding. The top plate 5 is fixedly connected to the ejector groove 19.

[0027] The winding mechanism includes a first drive motor 7, a first motor shaft 8, a threaded rod 9, a first slide groove 10, and a drive bracket 11. The first drive motor 7 is fixedly mounted on the winding table 1. The first motor shaft 8 is fixedly connected to the output end of the first drive motor 7. The threaded rod 9 is fixedly connected to the first motor shaft 8. The helical structure of the threaded rod 9 enables it to efficiently convert rotational motion into linear motion, or vice versa. The energy loss in this conversion process is relatively small, and the transmission efficiency is high. The first slide groove 10 is opened in the winding table 1, and the drive bracket 11 is threadedly connected to the threaded rod 9.

[0028] The winding mechanism also includes a mounting bracket 12, a second drive motor 13, a second motor shaft 14, a connecting shaft 15, and a protrusion 16. The mounting bracket 12 is integrally formed on the winding table 1. The second drive motor 13 is fixedly mounted on the drive bracket 11. The second motor shaft 14 is fixedly connected to the output end of the second drive motor 13. The connecting shaft 15 is fixedly connected to the second motor shaft 14. The protrusion 16 is fixedly connected to the connecting shaft 15. The protrusion 16 has a square structure and is the same size as the inner groove of the core 2. This allows the core 2 to rotate more stably and prevents large deviations.

[0029] The ejection mechanism includes a second slide 17, a spring 18, a limiting block 20, and a pushing cylinder 21. The second slide 17 is located in the winding table 1. When the ejection groove 19 moves up and down, the second slide 17 can limit it so that the ejection groove 19 will not tilt. This allows the top plate 5 and the electric heating knife 6 to be aligned with the core 2. The spring 18 is fixedly connected to the bottom end of the ejection groove 19. The two springs 18 are symmetrically arranged. The limiting block 20 is fixedly connected to the ejection groove 19. The pushing cylinder 21 is fixedly connected to the bottom end of the electric heating knife 6.

[0030] The functional principle of this utility model can be explained through the following operation methods:

[0031] First, place the core 2 between the two protrusions 16, then start the first drive motor 7. The first drive motor 7 drives the threaded rod 9 to rotate through the first motor shaft 8. The threaded rod 9 drives the two drive brackets 11 to move towards the center as a whole, as shown in the attached figure. Figure 3 As shown, when the protrusion 16 abuts against the inner groove of the core 2, the first drive motor 7 is turned off;

[0032] After clamping, the operator passes the film between the two clamping rods 4 and fixes it onto the core 2. Then, the second drive motor 13 is started. The second drive motor 13 drives the connecting shaft 15 and the protrusion 16 to rotate via the second motor shaft 14. The protrusion 16 drives the core 2 to rotate and wind up the film. Due to the action of the spring 18, the top plate 5 is always in contact with the film at the bottom of the core 2, making the film less likely to loosen. As the thickness of the wound film increases, the top plate 5 is pressed downward, and the spring 18 gradually returns to a contracted state. When winding is complete, the push cylinder 21 is activated, as shown in the attached... Figure 2 As shown, the cylinder 21 pushes the electric heating knife 6 upward to cut the film, while the top plate 5 flattens the tail roll to complete the winding.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
