Description

Technical Field

[0001] This utility model relates to the field of packaging film curing technology, specifically to a plastic flexible packaging film curing device. Background Technology

[0002] Curing refers to the process by which a semi-finished product after flexible packaging lamination undergoes a cross-linking reaction under specific conditions at a certain temperature and time to achieve optimal composite strength. Curing is also often referred to as solidification. Flexible packaging film is currently the most commonly used packaging film for food. During its production process, it needs to be cured by a curing device to facilitate the curing of the flexible packaging film, thereby giving it good tensile and peeling capabilities. At the same time, it also removes low-boiling-point residual solvents, such as ethyl acetate, reducing the amount of residual solvent and minimizing odors.

[0003] A search revealed a novel plastic flexible packaging film curing device in application number 201921028425.8. The device includes a curing unit body, a water outlet pipe at the lower end of the curing unit body, a water outlet valve on the surface of the water outlet pipe, a water inlet pipe on one side of the water outlet valve, a water inlet valve on the surface of the water inlet pipe, an air outlet pipe on the surface of the curing unit body, an exhaust pump at one end of the air outlet pipe, an air inlet pump on one side of the exhaust pump, an air inlet pipe at one end of the air inlet pump, an air outlet at one end of the air inlet pipe, a placement rack at the lower end of the air outlet, a rotating shaft at the lower end of the placement rack, and a heater inside the curing unit body. This novel plastic flexible packaging film curing device provides a more stable and uniform curing temperature during the curing process, effectively removes odors from the flexible packaging film, and prevents odors from affecting product quality and safety.

[0004] However, the above solutions still cannot solve the existing technical problems. For rolls of packaging film placed on a rack, the curing of packaging film is usually done by directly putting the rolls of semi-finished products into the equipment for curing. This results in the packaging film deforming and the curing uniformity being poor. Furthermore, direct contact with the rack allows the high temperature of the rack to be directly transferred to the packaging film, which may cause damage. Utility Model Content

[0021] 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;

[0022] Please see Figures 1-4 In this utility model, a plastic flexible packaging film curing device includes a curing box 1. Two sets of parallel guide rails 2 are fixedly connected inside the curing box 1. A packaging film roller 3 that can roll on the guide rails 2 overlaps between the two sides. A detachable rolling element 4 is provided on the left side of the packaging film roller 3. The detachable rolling element 4 is fixed in a straight line along the guide rail 2. A heating chamber 5 is opened at the bottom of the curing box 1. An electric heating plate 6 is provided inside the heating chamber 5. A guide plate 8 is provided between the heating chamber 5 and the interior of the curing box 1 at the top. A fan 7 is fixedly installed on the top of the curing box 1.

[0023] In this invention, the curing box 1 serves as the main body of the device. First, the packaging film roller 3 is removed from the two guide rails 2. Then, the detachable rolling element 4 is disassembled. Next, the packaging film is inserted onto the packaging film roller 3. Then, the detachable rolling element 4 is reconnected to the packaging film roller 3. Then, the entire packaging film roller 3 is re-clamped onto the two guide rails 2 located at the top. Then, it is pushed inward along the guide rails 2. Then, the above operation is repeated to install multiple packaging films in an alternating manner. Then, the curing box 1 is closed, the electric heating plate 6 inside the heating chamber 5 is activated, and the fan 7 is activated at the same time to make the hot airflow pass evenly through the interlaced and non-contact packaging film rolls to heat and cure them evenly. This achieves the advantages of the device having the ability to cure the packaging film without contacting the internal high-temperature structure, uniform curing, and resistance to damage. It solves the problems in the prior art where the above method leads to packaging film deformation and poor curing uniformity, and direct contact with the placement rack allows the high temperature of the placement rack to be directly transferred to the packaging film, which may cause damage.

[0024] Please see Figure 2 The detachable rolling element 4 includes an outer rotating wheel 41, a connecting block 42, and a bolt 43. The outer rotating wheel 41 is rotatably connected to the outside of the connecting block 42 and is rolled to the inside of the guide rail 2. The connecting block 42 is fixedly connected to one end of the packaging film roller 3 by the bolt 43.

[0025] In this utility model, the connecting block 42 is fixedly connected to the packaging film roller 3 by bolt 43, and then the outer rotating wheel 41 makes it roll inside the guide rail 2, so as to adjust the position of the packaging film roller 3 and facilitate the disassembly of the packaging film roller 3, making it convenient for loading and unloading.

[0026] Please see Figure 3 and Figure 4 The guide rail 2 has equidistantly arranged positioning grooves 21 inside its groove, and the outer side of the outer wheel 41 engages with the positioning grooves 21.

[0027] In this invention, the packaging film roller 3 is positioned by the positioning groove 21 in conjunction with the outer rotating wheel 41 to prevent it from rolling during heating.

[0028] Please see Figure 2 , Figure 3 and Figure 4 The positioning grooves 21 on the top two guide rails 2 and the positioning grooves 21 on the bottom two guide rails 2 are arranged alternately.

[0029] In this invention, the positioning grooves 21 at the top and bottom are arranged in an alternating manner so that the positioned packaging films do not come into contact with each other, allowing hot air to flow evenly upward through the gaps between the packaging films to achieve uniform cooking and heating.

[0030] Please see Figure 1 , Figure 3 and Figure 4 The guide plate 8 has evenly distributed air guide holes 81.

[0031] In this invention, the air guide plate 8 evenly directs heat to the interior of the curing box 1 through the air guide hole 81 to uniformly cure the packaging film.

[0032] Please see Figure 3 The maturation box 1 has a double door 9 on the front, and a handle 10 is installed on the double door 9.

[0033] In this invention, the double doors 9 and handles 10 facilitate the opening and closing of the curing box 1, making it easy to operate.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
