Description

Technical Field

[0001] This application relates to the field of drying equipment technology, and in particular to an automatic temperature-controlled drying system for an inner lining paper laminating machine. Background Technology

[0002] As the core material of tobacco packaging, cigarette liner paper often needs to be laminated with an aluminum foil layer on the surface of the liner paper to preserve aroma, prevent moisture and mold, and directly ensure the quality of cigarettes and the consumer experience.

[0003] The lamination process of base paper and aluminum foil is usually carried out on a laminating machine, refer to... Figure 1 The cigarette inner liner paper is conveyed to the wet lamination station 11 via the unwinding mechanism, while the cigarette aluminum foil is conveyed to the gluing station 12 via the unwinding mechanism. After gluing, it is conveyed to the wet lamination station 11, where the two are laminated and bonded. After lamination, the composite paper is conveyed to the coloring station 13 for coloring, and then to the drying mechanism 14 for drying. The dried composite paper can be dry-laminated with the inner liner transfer film at the dry lamination station 15, and finally pulled and wound onto the winding roller by the winding mechanism.

[0004] During the actual lamination process of the inner lining paper, the moisture content on the surface of the composite paper will dynamically change due to factors such as climate temperature variations and changes in material properties. Therefore, the drying temperature needs to be adjusted to match the product's moisture content, ensuring the quality of the lamination process. Adjusting the drying temperature requires changing the set temperature of the heating mechanism, while also requiring auxiliary heat dissipation from the air valves; the two are complementary.

[0005] In existing composite ovens, the opening angle of the flap inside the valve body cannot be seen in the conventional air valves. The adjustment of the air valves is made by technicians based on their operating experience, which easily leads to an imbalance in the air volume adjustment at the air inlet and outlet of the oven, resulting in frequent start-stop of the heating element. This situation will cause energy waste, and the heat generated by electric heating cannot be fully utilized, which will lead to increased equipment energy consumption and operating costs. This needs to be improved. Utility Model Content

[0006] Based on this, this application provides an automatic temperature-controlled drying system for an inner lining paper laminating machine, which can precisely adjust the air inlet and outlet volume of the drying oven assembly to facilitate the full utilization of heat energy and has the advantages of high efficiency and energy saving.

[0007] The automatic temperature-regulating drying system for an inner lining paper laminating machine provided in this application adopts the following technical solution: An automatic temperature-controlled drying system for an inner lining paper laminating machine includes: The oven assembly has two connecting pipes on its side, which serve as the air inlet and the air outlet, respectively. The damper mechanism consists of two sets, which are located inside the two connecting pipes. An adjustment mechanism is connected to the damper mechanism to adjust the opening degree of the damper mechanism; wherein, the adjustment mechanism includes a sliding seat slidably installed on the connecting pipe, a threaded rod rotatably mounted on the connecting pipe, and a servo motor for driving the threaded rod to rotate; the sliding seat is connected to the damper mechanism; the threaded rod partially passes through the inner side of the sliding seat and is threadedly connected to the sliding seat. The marking plate is located on the side of the connecting pipe. The marking plate has multiple opening marks, and the side of the sliding seat has an indicator part that is directly opposite the opening marks. The camera mechanism consists of two sets, with each camera facing a sliding seat and marking plate on a connecting pipe. The camera mechanism is connected to the central control module of the automatic temperature-controlled drying system. The display screen is used to display images captured by the two sets of cameras.

[0008] Optionally, a baffle is fixed in the middle of the connecting pipe, forming two air duct openings between the baffle and the inner wall of the connecting pipe; the air valve mechanism includes a lifting block that is vertically slidably disposed on the connecting pipe and two baffles that are horizontally slidably disposed on the connecting pipe, the lifting block being connected to a sliding seat; each baffle and the lifting block are provided with a hinge rod, one end of the hinge rod being hinged to the baffle and the other end being hinged to the lifting block; the two baffles are respectively disposed at the two air duct openings, and in the initial state, the baffles normally block the air duct openings.

[0009] Optionally, the side of the lifting block is provided with a connecting rod that connects to the sliding seat, and the side of the connecting pipe is provided with a vertical groove for the connecting rod to pass through; the side of the sliding seat near the connecting pipe is provided with a heat insulation pad, and the sliding seat and the heat insulation pad always block the vertical groove.

[0010] Optionally, the indicator is located in the middle of the sliding seat, and the end of the indicator is provided with an integrally formed arrow part; the marking plate is slidably installed on the connecting pipe, and the side of the marking plate near the indicator is provided with multiple inner grooves, each inner groove corresponding to each opening mark; the side of the marking plate is provided with an elastic element, which normally forces the marking plate to move towards the indicator and abut against it.

[0011] Optionally, a contact sensor is embedded in the inner wall of the groove, and the contact sensor is electrically connected to the central control module; when the arrow part matches and enters the groove, the central control module sends a control signal to force the servo motor to stop running.

[0012] Optionally, the opening indicators on the marking plate are arranged at intervals along the vertical direction, and the range value of each opening indicator is 0-50%.

[0013] Optionally, the automatic temperature-controlled drying system also includes a humidity sensor for detecting the moisture content of the inner lining paper surface and a central control module for reading the moisture content information. The humidity sensor is connected to the central control module for automatic adjustment and control of the drying temperature.

[0014] Optionally, the automatic temperature-controlled drying system also includes a temperature sensor located inside the oven assembly. The temperature sensor is connected to the central control module to monitor the internal temperature of the oven assembly in real time.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. The setup of two sets of cameras allows for separate image capture of the sides of the two connecting pipes. The captured images are transmitted to the central control module and displayed on the screen, which technicians can access for viewing. By checking the position of the indicator and the value of the opening mark it faces, the corresponding servo motor can be operated to force the indicators of the two adjustment mechanisms to point to the same opening mark, thus enabling precise adjustment of the air intake and exhaust volume of the oven assembly. The balanced airflow at the air intake and exhaust positions of the oven assembly ensures that the heating mechanism is in a stable heating state, facilitating the full utilization of heat energy and offering the advantages of high efficiency and energy saving.

[0016] 2. By setting an adjustment mechanism, the servo motor is controlled to rotate, which drives the sliding seat to move vertically, thereby forcing the lifting block to move vertically. When the lifting block moves, it drives the hinge rod to rotate, thereby forcing the two baffles to move closer to each other and gradually opening the air duct to facilitate the smooth exchange of air inside and outside the oven assembly.

[0017] 3. The installation of the heat insulation pad can ensure the sealing performance of the connecting pipe and reduce the loss of heat inside the connecting pipe to the outside air through the vertical groove, thereby reducing energy loss.

[0018] 4. The contact sensor embedded in the inner wall of the groove can change its state and transmit a signal to the central control module when the arrow enters the groove. The central control module can force the servo motor to stop operating, thereby keeping the arrow inside the groove, which can play an effective positioning role. It also makes it easy for the indicators of the two sets of adjustment mechanisms to point to the same opening value, improving the accuracy of air volume control.

[0019] 5. The humidity sensor can detect the moisture content on the surface of the inner lining paper, and the moisture content information can be transmitted to the central control module. The central control module uses an algorithm to calculate the optimal drying temperature and adjusts the heating mechanism, thereby keeping the drying temperature inside the drying oven assembly within the optimal range. This enables precise control of the drying temperature, meeting the drying process requirements of different products, and also meeting the dynamic moisture content requirements of the inner lining paper caused by factors such as climate change and changes in material properties during the production process.

[0022] The following is in conjunction with the appendix Figure 2 -Appendix Figure 6 This application will be described in further detail.

[0023] This application discloses an automatic temperature-controlled drying system for an inner lining paper laminating machine.

[0024] Reference Figure 2An automatic temperature-controlled drying system for an inner lining paper laminating machine 1 includes an oven assembly 2, an air valve mechanism 3, an adjustment mechanism 4, an identification plate 5, a camera mechanism, and a display screen 6; wherein, the side of the oven assembly 2 is provided with two connecting pipes 21, which can serve as the air inlet and air outlet of the oven assembly 2, respectively; see reference. Figure 3 The number of air valve mechanisms 3 is set to two sets, and the two sets of air valve mechanisms 3 are respectively set inside the two connecting pipes 21 to control the air intake and air output of the oven assembly 2 respectively.

[0025] Specifically, a horizontally arranged baffle 22 is fixed in the middle of the connecting pipe 21, forming two air duct openings 23 between the baffle 22 and the two opposite inner walls of the connecting pipe 21; a vertical sliding groove 211 is provided on the side of the connecting pipe 21, and the extension direction of the vertical sliding groove 211 is the same as the vertical direction. The air valve mechanism 3 includes a lifting block 31 and two baffles 32, and refers to... Figure 4 A connecting rod 311 is fixedly connected to the side of the lifting block 31. The connecting rod 311 passes through the vertical slide groove 211 and moves freely within the vertical slide groove 211, thereby realizing the sliding connection between the lifting block 31 and the connecting pipe 21.

[0026] Back Figure 3 Two baffles 32 are slidably connected to the inner wall of the connecting pipe 21, and each baffle 32 is connected to the lifting block 31 by a hinge rod 33. One end of the hinge rod 33 is connected to the baffle 32 and the other end is connected to the lifting block 31. The two baffles 32 are respectively set at the two air duct openings 23. In the initial state, that is, when the connecting pipe 21 is closed, the baffles 32 can normally block the air duct openings 23. In the working state, the lifting block 31 is moved upward by force, and the two baffles 32 can be moved closer to each other through the hinge rod 33, thereby opening the air duct openings 23.

[0027] Back Figure 2 There are two sets of regulating mechanisms 4, each set located within a separate set of air valve mechanisms 3. These mechanisms are used to adjust the opening degree of the air valve mechanisms 3, thereby changing the air intake and ventilation volume of the oven assembly 2. See details... Figure 4 The adjusting mechanism 4 includes a sliding seat 41, a threaded rod 42, and a servo motor 43. The sliding seat 41 is vertically slidably mounted on the side of the connecting pipe 21, and the end of the connecting rod 311 away from the lifting block 31 is connected to the sliding seat 41. In this embodiment, a heat insulation pad 44 is adhered to the side of the sliding seat 41 near the connecting pipe 21. During the vertical sliding process of the sliding seat 41, the heat insulation pad 44 always covers the vertical sliding groove 211 to maintain a good sealing effect of the connecting pipe 21 and reduce the leakage of internal hot air to the outside.

[0028] The threaded rod 42 is rotatably mounted on the side of the connecting pipe 21 and located below the sliding seat 41. The bottom surface of the sliding seat 41 is provided with a threaded groove 411. The threaded rod 42 is partially inserted into the threaded groove 411 and threadedly connected to the threaded groove 411. The servo motor 43 is fixed to the side of the connecting pipe 21. The output shaft of the servo motor 43 is coaxially connected to the end of the threaded rod 42 away from the sliding seat 41. Based on this, by controlling the operation of the servo motor 43, the threaded engagement between the threaded rod 42 and the threaded groove 411 can push the sliding seat 41 to slide vertically, thereby forcing the baffle plate 32 to move to adjust the opening of the air valve mechanism 3.

[0029] Back Figure 2 There are two sets of label plates 5, each set located on the side of one of the two connecting pipes 21, with each label plate 5 situated outside the sliding seat 41. (Refer to...) Figure 5 An elastic element 7 is provided on the side of the marking plate 5 away from the sliding seat 41. In this embodiment, the elastic element 7 is a spring. One end of the elastic element 7 abuts against the marking plate 5, and the other end of the elastic element 7 abuts against a spring seat 71, which is fixed to the side of the connecting pipe 21. The elastic element 7 can always generate an elastic force acting on the marking plate 5, thereby forcing the marking plate 5 to move normally towards the sliding seat 41.

[0030] The marking plate 5 has multiple opening marks 51 on its surface, each ranging from 0% to 50%. Specifically, there are six opening marks 51, representing 0%, 10%, 20%, 30%, 40%, and 50% respectively, and all opening marks 51 are spaced apart vertically. The side of the marking plate 5 near the sliding seat 41 has multiple recesses 52, the number of which is equal to the number of opening marks 51, and each recess 52 is directly opposite to its respective opening mark 51.

[0031] A partial indicator portion 412 is provided on the side of the sliding seat 41. The indicator portion 412 is integrally formed with the sliding seat 41, and the end of the indicator portion 412 is provided with an integrally formed arrow portion 413. The shape and size of the arrow portion 413 are adapted to the shape and size of the inner groove 52. Under the elastic force of the elastic member 7, the marking plate 5 can normally abut against the arrow portion 413. When the marking plate 5 moves to a position where the inner groove 52 is directly opposite the arrow portion 413, the arrow portion 413 can be matched and locked inside the inner groove 52.

[0032] Furthermore, each inner wall of the recess 52 is embedded with a contact sensor 53. The contact sensor 53 is electrically connected to the central control module of the automatic temperature-controlled drying system. When the arrow part 413 is matched and locked in the inner wall of the recess 52, the contact sensor 53 on the inner wall of the recess 52 can change its state and send a signal to the central control module, thereby causing the central control module to send a control signal to the servo motor 43 to force the servo motor 43 to stop running. Based on this, the stopping position of each arrow part 413 is more inclined to the inner wall of the recess 52. The arrow parts 413 of the two sets of sliding seats 41 are locked in the inner wall of the recess 52 that are directly opposite the same opening degree mark 51. This helps to keep the opening degree of the two sets of air valve mechanisms 3 consistent, thereby enabling precise adjustment of the air intake and exhaust volume of the oven assembly 2. This keeps the air volume at the air intake and exhaust positions of the oven assembly 2 balanced. At this time, the heating mechanism used to heat the air intake position can be in a stable heating state, which helps to make full use of heat energy and has the advantages of high efficiency and energy saving.

[0033] Two sets of camera units are provided (not shown in the figure). The two sets of camera units are respectively positioned outside the two connecting pipes 21, and the camera of each camera unit is directly facing the sliding seat 41 and the marking plate 5 on the connecting pipe 21. The camera units are communicatively connected to the central control module and can transmit the captured images to the central control module. Furthermore, refer to... Figure 6 The display screen 6 is mounted on the outside of the oven assembly 2. The display screen 6 is connected to the central control module and can display the images captured by the camera on the display screen 6 so that technicians can observe the opening status of the air valve mechanism 3 on the two connecting pipes 21 and ensure that the air volume at the air inlet and air outlet of the oven assembly 2 is kept balanced.

[0034] In addition, return Figure 2 The automatic temperature-controlled drying system in this embodiment also includes a humidity sensor and a temperature sensor 8, both of which are communicatively connected to the central control module. The humidity sensor detects the moisture content on the surface of the inner lining paper and transmits this information to the central control module. The central control module calculates the optimal drying temperature using a pre-programmed algorithm and adjusts the heating mechanism accordingly. This maintains the drying temperature inside the drying oven assembly 2 within the optimal range, enabling precise temperature control to meet the drying process requirements of different products and to accommodate dynamic changes in the moisture content of the inner lining paper caused by factors such as climate change and material properties during production. Temperature sensor 8 is located inside the oven assembly 2 to monitor the internal temperature of the oven assembly 2 in real time. Temperature sensor 8 also has a display panel located on the outside of the oven assembly, allowing technicians to quickly view the internal temperature of the oven assembly 2. During operation, temperature sensor 8 transmits the detected real-time temperature to the central control module. By comparing the detected real-time temperature with the optimal drying temperature calculated by the internal program of the central control module, it can be determined whether the automatic temperature-controlled drying system is operating normally. When there is a significant deviation between the optimal drying temperature and the real-time temperature, the central control system can activate a buzzer to sound an alarm to alert technicians, enabling timely handling and resolution of equipment problems.

[0035] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
