Description

A flattening device for composite packaging paper Technical Field

[0001] This application relates to the field of composite packaging paper processing technology, specifically a flattening device for composite packaging paper. Background Technology

[0002] Composite paper is made by bonding paper and paperboard with other plastics, aluminum foil, cloth, etc. with adhesives to obtain composite processed paper. Composite processed paper not only improves the appearance and strength of paper and paperboard, but also improves waterproof, moisture-proof, oil-resistant, airtight and aroma-preserving properties. At the same time, it also gains heat-sealing properties, light-blocking properties, and heat resistance.

[0003] In the production of composite paper, multiple layers of different papers are bonded together using glue. However, different paper materials have different physical properties such as water absorption rate. When using glue for bonding, different materials may absorb water, causing the entire composite paper to twist, thus affecting the quality of the final produced composite paper. In order to solve the above problems, a flattening device for composite packaging paper is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a flattening device for composite packaging paper, which can simultaneously achieve uniform heating and pressing during the drying process, thereby improving the flatness of the composite paper.

[0005] To achieve the above objectives, this application provides the following technical solution: a flattening device for composite packaging paper, comprising a base plate, a processing chamber, a conveyor belt, and a flattening mechanism. The flattening mechanism includes a heating box fixedly connected to the bottom surface of the base plate. A fan and a wind-powered heater are installed on the inner wall of the heating box. Five air supply pipes are connected to one side of the heating box. A flexible hose is connected to the output end of each air supply pipe. A metal ring is fixedly connected to the inner wall of the output end of each flexible hose. A bearing is fixedly connected to the inner wall of each metal ring. A connecting plate is provided at the top of the processing chamber. An adjustment mechanism is provided on the outside of the connecting plate. Five sets of brackets are fixedly connected to the bottom surface of the connecting plate. The five sets of brackets are slidably sleeved on the bottom of the processing chamber. A hollow pressure roller is rotatably connected to the bottom of each set of brackets. The outer surface of one end of each of the five hollow pressure rollers is fixedly connected to the inner wall of each of the five bearings. An air outlet is provided on the outer surface of each hollow pressure roller.

[0006] The above scheme utilizes a conveyor belt to transport composite packaging paper within the processing chamber. A leveling mechanism then evenly heats and presses the paper, improving its flatness. An adjustment mechanism allows for synchronized height adjustment of the five hollow pressure rollers, enabling the device to handle composite packaging paper of varying thicknesses. When the fan and electric heater are activated, external air is drawn into the heating chamber for heating. The hot air is then delivered through five air ducts to flexible hoses, and finally, through metal rings and bearings, to the hollow pressure rollers. The hot air is exhausted through exhaust vents. Simultaneously, the hollow pressure rollers contact the composite packaging paper conveyed by the conveyor belt, achieving simultaneous drying and flattening, making the system more practical.

[0007] Furthermore, both the processing chamber and the conveyor belt are fixedly connected to the upper surface of the base plate, and the conveyor belt passes through the processing chamber and extends to the outside of the processing chamber.

[0008] Through the above scheme, the conveyor belt can transport the composite packaging paper inside the processing chamber, thereby facilitating the flattening of the composite packaging paper.

[0009] Furthermore, the outer surfaces of all five air supply pipes are fixedly connected to one side of the inner wall of the processing chamber.

[0010] The above scheme defines the location and status of the five air supply ducts, thereby facilitating subsequent drying work.

[0011] Furthermore, the adjustment mechanism includes a U-shaped frame fixedly connected to the upper surface of the processing chamber and two lead screws rotatably sleeved on the upper surface of the processing chamber, with the tops of the two lead screws rotatably sleeved on both sides of the U-shaped frame.

[0012] The above solution, through the U-shaped frame, allows the lead screw to rotate more stably at the top of the processing chamber.

[0013] Furthermore, the two sides of the connecting plate are respectively threaded to the outer surfaces of the two lead screws, and a knob is fixedly connected to the top of each lead screw.

[0014] The above solution increases the contact area at the top of the lead screw by using a knob, thus facilitating the rotation of the lead screw.

[0015] Furthermore, a sprocket is fixedly connected to the outer surface of each lead screw, and a chain is provided above the U-shaped frame, with the two sprockets connected by chain drive.

[0016] The above scheme allows the two lead screws to rotate simultaneously in the same direction by cooperating with the sprocket and chain, thus facilitating the adjustment of the position of the connecting plate.

[0017] Furthermore, a controller is fixedly connected to the outer surface of the processing chamber, and the electrical components in the conveyor belt and leveling mechanism are all electrically connected to the controller.

[0018] The above solution simplifies the operation process and makes the controller easier to use.

[0019] Furthermore, support columns are fixedly connected to the four corners of the bottom surface of the base plate, and an anti-slip pad is fixedly connected to the bottom surface of each support column.

[0020] The above solution allows the base plate to be stably placed on the contact surface using the support columns, which facilitates the flattening of the composite packaging paper.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This composite packaging paper leveling device uses a conveyor belt to transport the composite packaging paper inside the processing chamber. A leveling mechanism then evenly heats and presses the paper, improving its flatness. An adjustment mechanism allows for simultaneous height adjustment of five hollow pressure rollers, enabling the device to handle composite packaging papers of varying thicknesses. When the fan and electric heater are activated, external air is drawn into the heating chamber and heated. The hot air is then delivered through five air ducts to flexible hoses and, via metal rings and bearings, to the hollow pressure rollers. The hot air is then exhausted through exhaust vents. Simultaneously, the hollow pressure rollers contact the composite packaging paper conveyed by the conveyor belt, achieving simultaneous drying and leveling, making it more practical.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please refer to Figures 1, 2, and 4. In this embodiment, a flattening device for composite packaging paper includes a base plate 1, a processing chamber 2, a conveyor belt 3, and a flattening mechanism 4. The processing chamber 2 and the conveyor belt 3 are both fixedly connected to the upper surface of the base plate 1. The conveyor belt 3 passes through the processing chamber 2 and extends to the outside of the processing chamber 2. The conveyor belt 3 is an existing device, so it will not be described in detail. The conveyor belt 3 can transport the composite packaging paper inside the processing chamber 2, thereby facilitating the flattening process of the composite packaging paper. Support columns 7 are fixedly connected to the four corners of the bottom surface of the base plate 1. Each support column 7 has an anti-slip pad fixedly connected to its bottom surface. The support columns 7 can stably place the base plate 1 on the contact surface, thereby facilitating the flattening process of the composite packaging paper.

[0033] Please refer to Figures 2, 3, and 4. The leveling mechanism 4 includes a heating box 401 fixedly connected to the bottom surface of the base plate 1. A fan 402 and a wind-powered heater 403 are installed on the inner wall of the heating box 401. When the fan 402 is started, it can draw outside air into the heating box 401 and deliver it to the wind-powered heater 403. When the wind-powered heater 403 is started, it can heat the air delivered by the fan 402, thereby facilitating the subsequent drying work. Five air supply pipes 404 are connected to one side of the heating box 401. The outer surfaces of the five air supply pipes 404 are all fixedly connected to one side of the inner wall of the processing chamber 2, which limits the position and state of the five air supply pipes 404, thereby facilitating the subsequent drying work.

[0034] Please refer to Figures 4, 5, and 6. Each air supply duct 404 has an output end connected to a flexible hose 405. The hose 405 can deform appropriately without affecting the internal gas delivery. A metal ring 406 is fixedly connected to the inner wall of the output end of each hose 405, and a bearing 407 is fixedly connected to the inner wall of each metal ring 406. A connecting plate 408 is provided at the top of the processing chamber 2, and an adjustment mechanism 5 is provided on the outside of the connecting plate 408. Five sets of supports 409 are fixedly connected to the bottom surface of the connecting plate 408. All five sets of supports 409 are slidably fitted onto the bottom of the processing chamber 2. A hollow pressure roller 410 is rotatably connected to the bottom of each set of supports 409. The outer surface of one end of each of the five hollow pressure rollers 410 is fixedly connected to the inner wall of each of the five bearings 407. The hot air delivered in the air supply duct 404 is delivered to the hollow pressure roller 410 through the hose 405, metal ring 406, and bearing 407. The outer surface of each hollow pressure roller 410 is open... Equipped with an air outlet 411, the hollow pressure roller 410 itself has a certain weight. When the conveyor belt 3 transports the composite packaging paper into the processing chamber 2, the surface of the hollow pressure roller 410 will contact the upper surface of the composite packaging paper, thus flattening the composite packaging paper. The air outlet 411 on the surface of the hollow pressure roller 410 can directly discharge the hot air inside the hollow pressure roller 410 onto the composite packaging paper, thereby improving the drying effect of the composite packaging paper. Furthermore, when the conveyor belt 3 transports the composite packaging paper, the friction between the composite packaging paper and the hollow pressure roller 410 can cause the hollow pressure roller 410 to rotate, which can deliver the hot air to different positions, thereby improving the drying quality. A controller 6 is fixedly connected to the outer surface of the processing chamber 2. The electrical components in the conveyor belt 3 and the flattening mechanism 4 are all electrically connected to the controller 6. The controller 6 simplifies the operation process and makes it convenient to use.

[0035] Please refer to Figures 2, 3, and 4. The adjustment mechanism 5 includes a U-shaped frame 501 fixedly connected to the upper surface of the processing chamber 2 and two lead screws 502 rotatably sleeved on the upper surface of the processing chamber 2. The tops of the two lead screws 502 are respectively rotatably sleeved on both sides of the U-shaped frame 501. The U-shaped frame 501 allows the lead screws 502 to be more stably rotatably connected to the top of the processing chamber 2. The two sides of the connecting plate 408 are respectively threaded to the outer surfaces of the two lead screws 502. A knob 505 is fixedly connected to the top of each lead screw 502. The knob 505 can increase the contact area of ​​the top of the lead screw 502, thereby facilitating the rotation of the lead screw 502. The outer surface of each lead screw 502 is fixedly connected to... A sprocket 503 is connected to the top of the U-shaped frame 501, and a chain 504 is provided above it. The two sprockets 503 are connected by the chain 504. Through the cooperation of the sprockets 503 and the chain 504, the two lead screws 502 can rotate simultaneously in the same direction, which facilitates the adjustment of the position of the connecting plate 408. When the position of the connecting plate 408 changes, the position of the five hollow pressure rollers 410 can be finely adjusted. In order to avoid the change of position of the hollow pressure rollers 410 from affecting the normal operation of other components, a flexible hose 405 is used as a bridge for transporting gas between the air supply pipe 404 and the hollow pressure rollers 410. The flexible hose 405 can undergo appropriate deformation without being damaged.

[0036] In this embodiment, a flattening device for composite packaging paper is provided. A conveyor belt 3 transports the composite packaging paper inside the processing chamber 2. A flattening mechanism 4 uniformly heats and presses the composite packaging paper transported by the conveyor belt 3 to improve the flatness of the composite paper. An adjustment mechanism 5 synchronously adjusts the height of the five hollow pressure rollers 410, enabling the device to meet the processing requirements of composite packaging paper of different thicknesses. When the fan 402 and the wind-powered heater 403 are started, external air is drawn into the heating chamber 401 for heating. The hot air is then delivered to the hoses 405 through five air ducts 404, and then to the hollow pressure rollers 410 through metal rings 406 and bearings 407. The hot air is exhausted through the air outlet 411. Simultaneously, the hollow pressure rollers 410 contact the composite packaging paper transported by the conveyor belt 3, thus achieving simultaneous drying and flattening, making it more practical.

[0037] The working principle of the above embodiment is as follows: The composite packaging paper is placed on the conveyor belt 3, and the conveyor belt 3 is started to transport the composite packaging paper into the processing chamber 2. Then, the blower 402 and the electric heater 403 are started to dry the composite packaging paper inside the processing chamber 2. When the blower 402 starts, it draws outside air into the heating chamber 401. The air is then heated by the electric heater 403 to form hot air. The hot air is delivered through five air supply pipes 404 to five flexible hoses 405. Then, through the metal ring 406 and bearing 407, the hot air is delivered to the hollow pressure roller 410. Finally, the hot air is discharged through the air outlet 411 on the surface of the hollow pressure roller 410, thus drying the composite packaging paper. Simultaneously, the outer surface of the hollow pressure roller 410 contacts the upper surface of the composite packaging paper transported by the conveyor belt 3. The friction between the hollow pressure roller 410 and the composite packaging paper allows the hollow pressure roller 410 to rotate. This rotation delivers hot air to different locations, enabling the composite packaging paper to undergo more comprehensive drying. Simultaneously, the hollow pressure roller 410 flattens the composite packaging paper upon contact, achieving simultaneous drying and flattening, thus optimizing the device's performance. Finally, the adjustment mechanism 5 allows for synchronized fine-tuning of the positions of the five hollow pressure rollers 410, enabling the device to process composite packaging paper of varying thicknesses. To prevent changes in the position of the hollow pressure roller 410 from affecting other components, a flexible hose 405 is installed between the hollow pressure roller 410 and the air supply pipe 404. Small changes in distance will not damage the flexible hose 405.
