Description

Technical Field

[0001] This utility model belongs to the technical field of plastic packaging bag production, and more specifically, it relates to a curing device for plastic packaging bag production. Background Technology

[0002] In the production of plastic packaging bags, curing is a crucial process. Its purpose is to fully cure the adhesive between the composite layers of the packaging bag through constant temperature and time curing, thereby improving composite strength and peel force, and ensuring the sealing and durability of the packaging bag. Existing curing equipment typically achieves uniform temperature in the curing chamber through unidirectional airflow. However, the airflow is mostly in a fixed direction, leading to differences in temperature and airflow velocity in different areas of the curing chamber. This is especially problematic in large curing chambers or for multi-layered packaging bags, where inconsistent curing levels between the edges and the center can occur, affecting product quality stability. Furthermore, some curing equipment has a fixed airflow guidance structure, making it impossible to flexibly adjust the airflow direction according to the size and arrangement of the packaging bags, resulting in poor adaptability and limiting production efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a curing device for the production of plastic packaging bags. This device solves the technical problem that curing is a critical process in the production of plastic packaging bags, and that existing devices suffer from fixed airflow direction and uneven distribution, resulting in inconsistent curing, poor adaptability, and negative impacts on product quality and production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a curing device for producing plastic packaging bags, comprising a curing chamber with an opening, one end of which has a movable through-hole, a frame slidably connected to the opening, a plurality of shafts rotatably connected to the frame, a guide plate fixedly connected to each shaft, a threaded sleeve threadedly connected to each shaft, a rubber pad fixedly connected to each threaded sleeve, and the rubber pads contacting the frame, a box fixedly connected to one end of the curing chamber, and a first pipe assembly fixedly connected to one end of the curing chamber.

[0005] As a preferred embodiment of this utility model, the two first pipe groups are respectively fixedly connected to the corresponding air pumps, the two air pumps are fixedly connected to the curing chamber, the two air pumps are respectively fixedly connected to the corresponding housing, the two housings are threaded with heating rods, the two housings are fixedly connected to the second pipe groups, the two second pipe groups are fixedly connected to the curing chamber, and are placed vertically and vertically with the multiple guide plates.

[0006] As a preferred technical solution of this utility model, the inner wall of the curing chamber is fixedly connected with first mesh plates at equal intervals, and the plurality of first mesh plates are all U-shaped. One end and the other end of the curing chamber are fixedly connected with second mesh plates, and the two second mesh plates are respectively placed in relation to the corresponding first pipe groups.

[0007] As a preferred embodiment of this utility model, both the curing chamber and the box are hinged with doors.

[0008] As a preferred embodiment of this utility model, the frame is fixedly connected with a handle.

[0009] As a preferred embodiment of this utility model, a rubber strip is fixedly connected at the contact point between the opening and the frame.

[0010] This utility model provides a curing device for the production of plastic packaging bags, which has the following beneficial effects:

[0011] 1. This new invention utilizes the cooperation between a curing chamber, an opening, a frame, shafts, guide plates, and threaded sleeves. The frame is slidably connected at the opening of the curing chamber, and multiple shafts with guide plates are rotatably mounted on the frame. Combined with the threaded sleeves and rubber pad locking structure connected to the shafts, this design allows for flexible adjustment of the angles of the guide plates by rotating the shafts, transforming unidirectional airflow into multidirectional delivery. This solves the problem of temperature and airflow velocity differences in different areas of the curing chamber caused by fixed airflow in existing curing devices, avoiding inconsistent curing levels between the edges and center of packaging bags in multi-layered or large curing chambers, thus ensuring product quality stability. Furthermore, the threaded sleeves drive the rubber pads into tight contact with the frame, locking the adjustment positions of the shafts and guide plates and preventing displacement under airflow impact. Simultaneously, the sliding connection of the frame facilitates disassembly and maintenance, and the angle of the guide plates can be flexibly adapted to the specifications and placement of plastic packaging bags, overcoming the drawbacks of fixed and poorly adaptable traditional airflow guiding structures, significantly improving production efficiency.

[0012] 2. Through the cooperation between the first and second mesh plates, multiple layers of the first mesh plate are used to place plastic packaging bags. This not only improves the space utilization of the curing chamber and allows for more products to be cured, but also ensures smooth airflow through each layer of packaging bags through the breathable structure of the mesh plate, allowing hot air to evenly cover every area and avoiding insufficient or excessive curing in certain areas. At the same time, a second mesh plate is installed at the first pipe assembly that extracts air from the curing chamber. This effectively filters impurities, dust, and adhesive debris from the air, prevents the first pipe assembly from becoming clogged, ensures stable operation of the air extraction system, extends the service life of the equipment, and further improves the stability and production efficiency of the curing process.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a curing device for producing plastic packaging bags, including a curing chamber 1, an opening 2 in the curing chamber 1, and a movable through-hole at one end and the other end of the opening 2, allowing a frame 3 to move in or out of the opening 2. The opening 2 is slidably connected to the frame 3, and the frame 3 is rotatably connected to multiple shafts 4. Each shaft 4 is fixedly connected to a guide plate 5, and the shaft 4 can drive the corresponding guide plate 5 to rotate. By utilizing the placement angle of the guide plate 5, the delivered air can be guided in different directions. Each shaft 4 is threadedly connected to a threaded sleeve 6, and each threaded sleeve 6 is fixedly connected to a rubber pad 7. Each rubber pad 7 is in contact with the frame 3, and by utilizing the contact friction, the shaft 4 can drive the guide plate 5 to adjust the angle and then fix it. Each end of the curing chamber 1 is fixedly connected to a box 10, and each end of the curing chamber 1 is fixedly connected to a first pipe group 8, which is used to extract air from the curing chamber 1.

[0022] Two first pipe groups 8 are fixedly connected to corresponding air pumps 9. The air pumps 9 can use the first pipe groups 8 to extract air from the curing chamber 1. The model of the air pumps 9 is selected according to actual working requirements. Both air pumps 9 are fixedly connected to the curing chamber 1 and are fixedly connected to the corresponding housing 10. Air can be delivered to the housing 10 through the air pumps 9. Both housings 10 are threaded with heating rods 11. The heating rods 11 are electrically heated, and the model is selected according to actual working requirements. After the air enters the housing 10, it will be heated by the heating rods 11 to facilitate the curing operation of the plastic. Both housings 10 are fixedly connected to second pipe groups 12. The second pipe groups 12 are used to re-inject the heated air into the curing chamber 1. Both second pipe groups 12 are fixedly connected to the curing chamber 1 and are placed vertically and vertically with multiple guide plates 5, so that the air delivered by the second pipe groups 12 can flow in multiple directions through the guidance of multiple guide plates 5.

[0023] The curing chamber 1 has a first mesh plate 15 fixedly connected at equal intervals on the inner wall. The first mesh plates 15 are all U-shaped. The first mesh plates 15 are used to place plastic packaging bags that need to be cured. The shape of the first mesh plates 15 makes it convenient to place or remove the plastic packaging bags after the door 13 of the curing chamber 1 is opened. The curing chamber 1 has a second mesh plate 16 fixedly connected to one end and the other end. The two second mesh plates 16 are respectively placed in relation to the corresponding first tube group 8. The second mesh plates 16 are used to filter and intercept impurities to prevent them from entering the first tube group 8 along with the air.

[0024] Both the curing chamber 1 and the housing 10 are hinged with doors 13, which facilitates the placement of items or cleaning of the curing chamber 1, as well as the cleaning of the housing 10 or the maintenance of the heating rod 11.

[0025] The frame 3 is fixedly connected to a handle 14, which is used to pull the frame 3 out.

[0026] A rubber strip 17 is fixedly connected at the contact point between the opening 2 and the frame 3 to increase the sealing performance.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In use, the frame 3 is first slidably installed at the opening 2 of the curing chamber 1. The angles of the guide plates 5 are flexibly adjusted by rotating the shaft 4 to adapt to the specifications and placement of the plastic packaging bags. Then, the threaded sleeve 6 on the shaft 4 is tightened, causing the rubber pad 7 to contact the frame 3 and lock the position of the shaft 4 to prevent displacement under the impact of airflow. Next, the plastic packaging bags to be cured are placed in layers using the multi-layer first mesh plate 15 to fully improve the space utilization of the curing chamber 1. At the same time, a second mesh plate 16 is installed at the first pipe group 8 that extracts air from the curing chamber 1. When the air pump 9 and the heating rod 11 are both connected to an external power supply and control device, the operation is complete. During operation, the first pipe group 8 extracts air from the curing chamber 1 and passes through the air pump 9, the heating rod 11 in the box 10, and the second pipe group 12 before flowing back into the curing chamber 1. The injected air is guided by the guide plate 5 to a multi-directional airflow that can smoothly penetrate each layer of packaging bags through the breathable structure of the first mesh plate 15, achieving uniform hot air coverage and avoiding local curing abnormalities. The second mesh plate 16 filters impurities, dust, and adhesive debris in the air to prevent the first pipe group 8 from clogging and ensure the stable operation of the air extraction system. This not only extends the service life of the equipment but also significantly improves production efficiency through uniform curing and efficient loading.
