Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging and processing, and in particular to a carton beautification device. Background Technology

[0002] In existing cigarette carton packaging production lines, after the carton is wrapped in transparent paper, its exterior is typically shaped using a carton shaping container to improve the finished product's appearance. During continuous batch production, the stability of this shaping effect directly affects the consistency of the product's appearance.

[0003] However, in actual production, the thinness of the label paper material for flexible packaging results in insufficient pressure support after the product is formed, often leading to poor finishing effects. For example, wrinkles, ripples, poor adhesion, or unevenness may occur on the transparent paper surface. These problems not only affect packaging quality but may also cause some products to fail to meet appearance standards, reducing the overall pass rate. This phenomenon is particularly frequent when the transparent paper material is thin or when equipment operating speed fluctuates, affecting stable product output.

[0004] Currently, the equipment structure offers limited solutions to these problems, and the packaging process still heavily relies on manual adjustment of operating parameters and operator experience, resulting in some fluctuations in the appearance quality of the finished product. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor cosmetic results caused by inadequate adhesion, wrinkles, and ripples in existing cosmetic packaging processes. This invention provides a cosmetic packaging device that improves the adhesion of the transparent paper on the surface of the packaging before cosmetic procedures, thereby enhancing the consistency and stability of the finished product's appearance.

[0006] The inventors discovered that problems such as wrinkles and curling in existing beauty product packaging processes are not entirely due to improper temperature or pressure control of the equipment. Rather, it's because the transparent paper, after being applied to the packaging, undergoes slight deformation due to uneven stress before entering the beauty container, especially noticeable during high-speed operation. Further analysis revealed that during the brief stabilization phase after wrapping, the thermal expansion and contraction properties of the materials cause uneven localized stress between the transparent paper and the label paper, resulting in initial unevenness on the bonding surface. Once the packaging enters the beauty container for heating and pressing, these areas of concentrated stress are highly susceptible to developing permanent wrinkles or improper bonding.

[0007] To solve the above-mentioned technical problems, this utility model discloses a strip-shaped beauty device, comprising:

[0008] A hair dryer mechanism, which has an air outlet;

[0009] The preheating mechanism includes a support and a heater mounted on the support. The support has a through hole, and the air outlet faces the through hole. The heater is used to heat the air output from the air outlet.

[0010] The carton beauty container is located on one side of the preheating mechanism and is used to heat and shape the transparent paper wrapped around the carton output by the preheating mechanism.

[0011] During operation, the blower mechanism and heater start working first. Once the airflow from the blower mechanism and the temperature of the heater stabilize, the carton enters the preheating mechanism. At this point, the air from the blower mechanism is heated after passing through the heater and blown through the through-hole onto the transparent paper covering the carton. As the carton continues to move, the transparent paper surface remains continuously exposed to hot air. After passing through the preheating mechanism, the carton enters the carton shaping container, where the transparent paper covering it is heated and shaped.

[0012] By adopting the above technical solution, the transparent paper is preheated before entering the beauty container, allowing it to undergo hot air treatment before entering the beauty process. This puts it in a preliminary heat-shrinking state, improving its shrinkage performance and uniformity. This effectively alleviates adhesion defects caused by uneven internal stress of the material, making it easier to adhere to the surface of the transparent paper during subsequent beauty procedures. This helps reduce surface wrinkles, ripples, and other appearance abnormalities, and improves the consistency and stability of the beauty effect of the transparent paper during the beauty stage.

[0013] Optionally, it also includes a conveyor belt for conveying the strip boxes, with the preheating mechanism and the strip box container arranged sequentially above the conveyor belt along the conveying direction.

[0014] Optional, the support includes:

[0015] The mounting plate spans across the top of the conveyor belt along its width.

[0016] At least one support plate is provided below the mounting plate to support the mounting plate;

[0017] The through hole is located on the mounting plate, and the heater is located above the mounting plate and covers the through hole. There is a certain distance between the heater and the upper surface of the conveyor belt, and the strip box on the conveyor belt can pass under the mounting plate.

[0018] Optionally, the distance between the heater and the upper surface of the conveyor belt is 250–300 mm.

[0019] Optionally, there are at least two through holes, which are arranged sequentially at intervals along the width of the conveyor belt. Each through hole is equipped with a heater above it, and there are multiple air outlets, each of which faces the corresponding through hole.

[0020] Optionally, the air outlet direction of the blower mechanism has an angle of less than 90° with the conveyor belt conveyor direction, and the air outlet direction of the blower mechanism is tilted towards the side closer to the beauty device.

[0021] Optionally, the angle between the air outlet direction of the blower mechanism and the conveying direction of the conveyor belt is 60°.

[0022] Optionally, the heater is a PTC heater.

[0023] Optionally, the blower mechanism includes a fan, which is a centrifugal fan driven by an EC motor.

[0024] Optionally, a control unit may also be included, which includes:

[0025] Speed ​​sensor, used to detect the running speed of the conveyor belt;

[0026] The temperature control module is electrically connected to the speed sensor, PTC heater, and fan. The temperature control module is used to adjust the power of the PTC heater and the output speed of the fan according to the running speed of the conveyor belt. The power of the PTC heater and the output speed of the fan are both positively correlated with the running speed of the conveyor belt.

[0027] Optionally, the preheating mechanism also includes a temperature control probe, which is located at the center of the bottom of the mounting plate and is used to detect the temperature of the hot air sprayed onto the surface of the transparent paper.

[0028] Optionally, the temperature control probe is electrically connected to the temperature control module, which is also used to control the heater to stop working when the temperature control probe detects that the hot air temperature exceeds the set threshold. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0037] To address the problems of poor cosmetic results caused by inadequate adhesion, wrinkles, and ripples in the transparent paper during the cosmetic packaging process in existing technologies, this utility model discloses a cosmetic packaging device to improve the adhesion of the transparent paper on the surface of the packaging box before cosmetic surgery, thereby enhancing the consistency and stability of the finished product's appearance.

[0038] like Figure 1 As shown, the beauty device for strip boxes provided in this embodiment includes a blower mechanism (not shown), a preheating mechanism 1, and a beauty box container 5. The preheating mechanism 1 is mainly used to heat the air output by the blower mechanism and to preheat the transparent paper on the surface of the strip box 6 before it enters the beauty box container 5, thereby creating favorable conditions for subsequent shaping. The beauty box container 5 is located downstream of the preheating mechanism 1 and is used to heat and shape the transparent paper wrapped around the strip box 6 output by the preheating mechanism 1.

[0039] refer to Figure 2 The preheating mechanism 1 includes a support 2 and a heater 4 mounted on the support 2. The support 2 has a through hole 3, and the air outlet of the blower mechanism is located above and facing the through hole 3. The through hole 3 is used to form an airflow channel. The heater 4 is used to heat the air output by the blower mechanism, thereby forming hot air for preheating the transparent paper.

[0040] During operation, the blower mechanism and heater 4 start working first. When the air speed output by the blower mechanism and the temperature of the heater 4 are basically stable, the carton 6 enters the preheating mechanism 1. At this time, the air output by the blower mechanism is heated after passing through the heater 4 and blown through the through hole 3 onto the surface of the transparent paper covering the outside of the carton 6. As the carton 6 continues to move, the surface of the transparent paper is continuously subjected to hot air. After passing through the preheating mechanism 1, the carton 6 enters the carton beauty container 5, where the carton beauty container 5 heats and shapes the transparent paper covering its outside.

[0041] By employing the above technical solution, the transparent paper is preheated in the preheating mechanism 1 before entering the beauty container 5. This allows the transparent paper to undergo hot air treatment before entering the beauty process, putting it into a preliminary thermal shrinkage state. This improves shrinkage performance and uniformity, effectively alleviating adhesion defects caused by uneven internal stress of the material. Consequently, it adheres more easily to the surface of the transparent paper during subsequent beauty procedures, helping to reduce surface wrinkles, ripples, and other appearance abnormalities, and improving the consistency and stability of the beauty results. Furthermore, preheating the transparent paper with hot air ensures even heating, further enhancing the preheating effect.

[0042] In some embodiments of this application, the strip beauty device further includes a conveyor belt 9 for conveying the strip 6, the preheating mechanism 1, and the strip beauty container 5 along the conveying direction of the conveyor belt 9 (e.g., Figure 1 The X-direction shown is arranged sequentially above the conveyor belt 9, and the carton 6 conveyed on the conveyor belt 9 can sequentially enter the preheating mechanism 1 and the carton beauty container 5. For example, in order to avoid heat loss, the distance between the preheating mechanism 1 and the carton beauty container 5 can be 150±10mm.

[0043] Furthermore, the bracket 2 includes a mounting plate 7 and at least one support plate 8. The support plate 8 is disposed below the mounting plate 7 to support and fix the mounting plate 7, ensuring its stable installation in a preset position. The mounting plate 7 spans across the top of the conveyor belt 9 along its width direction, supporting the functional components of the preheating mechanism 1. For example, as... Figure 1 As shown, the mounting plate 7 is rectangular in shape, and there are four support plates 8, which are connected to the four edges of the mounting plate 7. The mounting plate 7 and the four support plates 8 together form a box. This structure can effectively prevent heat loss.

[0044] A through-hole 3 is provided on the mounting plate 7. A heater 4 is mounted above the mounting plate 7 and covers the through-hole 3. A certain distance is maintained between the heater 4 and the upper surface of the conveyor belt 9, and the strip boxes 6 on the conveyor belt 9 can pass under the mounting plate 7 during operation. This structure facilitates the formation of a modular support 2 arrangement, ensuring a clear airflow path, smooth passage of the strip boxes 6, and convenient installation and maintenance of the equipment. For example, the mounting plate 7 and the support plate 8 are made of 304 stainless steel to ensure the stability of the equipment. For example, the mounting plate 7 is 300mm long and 120mm wide.

[0045] Furthermore, the vertical distance between the center point of heater 4 and the strip box 6 is 250-300mm. The applicant discovered that when the vertical distance between heater 4 and strip box 6 is too small, heater 4 directly heats the transparent paper on the surface of strip box 6. This results in excessive heat distribution to the transparent paper, leading to uneven heating and potential melting or deformation. Conversely, when the distance is too large, the temperature of the hot air decreases excessively upon reaching the transparent paper surface of strip box 6, and the airflow path is too long, causing uneven coverage and wasting heat, thus affecting the preheating effect.

[0046] This application sets the vertical distance between the heater 4 and the strip box 6 to 250-300mm, so that the hot air has a reasonable temperature attenuation and blowing area when it reaches the transparent paper surface of the strip box 6. This can prevent the heater 4 from being too close and causing heat melting and deformation, while ensuring that the hot air coverage is uniform, thus improving the preheating uniformity and safety of the transparent paper.

[0047] Furthermore, the number of through holes 3 can be at least two, with each through hole 3 spaced apart along the width of the conveyor belt 9, and a heater 4 is provided above each through hole 3. The blower mechanism has multiple air outlets, each facing its corresponding through hole 3. This structure allows for more uniform hot air distribution, is suitable for multi-pack synchronous operation on wide-width packaging lines, avoids localized overheating caused by concentrated hot air, and enhances overall heating efficiency.

[0048] Furthermore, the airflow direction of the hair dryer (such as...) Figure 2 (as shown in the Y direction) and the conveying direction of conveyor belt 9 (as shown in the Y direction) and conveying direction of conveyor belt 9 (as shown in the Y direction) Figure 2 There is an angle of less than 90° between them (as shown in the X direction in the diagram). Figure 2 As shown by the included angle α, the air outlet direction of the blower mechanism is tilted towards the side closer to the carton container 5, thereby forming an oblique blowing structure and expanding the hot air coverage area. By setting the airflow at an oblique angle, the action path of the hot air on the surface of the transparent paper can be extended, improving the hot air utilization rate, while reducing the impact on the carton 6 and ensuring the stability of the packaging process. For example, the included angle between the air outlet direction of the blower mechanism and the conveying direction of the conveyor belt 9 is 60°.

[0049] In some embodiments of this application, heater 4 is selected as a PTC heater. PTC heaters possess self-limiting temperature performance and rapid heating capability, exhibiting high stability. Using a PTC heater effectively avoids temperature overshoot, ensures constant and safe hot air output, extends equipment lifespan, and improves heating efficiency.

[0050] Furthermore, the blower mechanism includes a fan (not shown in the figure) and an air duct (not shown in the figure). One end of the air duct is connected to the exhaust port of the fan, and the other end can be spaced a certain distance from the heater 4, or it can be fitted over the heater 4. Specifically, the outer surface of the heater 4 is provided with a heat insulation layer to prevent damage to the air duct fitted over the heater 4. The fan is a centrifugal fan driven by an EC motor. This type of fan has the characteristics of adjustable speed, low energy consumption, and fast response. The fan can intelligently adjust its speed according to the system load to achieve fine-grained airflow control, which helps to maintain a stable output of hot air. For example, the rated output power of the fan is 2.2kW.

[0051] Furthermore, the strip-shaped beauty device also includes a control unit (not shown in the figure), which includes a speed sensor (not shown in the figure) and a temperature control module (not shown in the figure). The speed sensor is used to detect the running speed of the conveyor belt 9; the temperature control module is electrically connected to the speed sensor, the PTC heater 4, and the fan, respectively. The temperature control module is used to adjust the power of the PTC heater 4 and the output speed of the fan according to the running speed of the conveyor belt 9. The power of the PTC heater 4 and the output speed of the fan are both positively correlated with the running speed of the conveyor belt 9.

[0052] In this embodiment, the actual temperature T of the hot air received by the transparent paper on the surface of the carton 6 can range from 45 to 85°C, and the initial set temperature T0 can be 65°C. T0 is a fixed target temperature that is manually set or preset and usually does not change automatically with the operation of the system. During operation, the PLC intelligent temperature control system in the temperature control module adopts a "PID + fuzzy control algorithm" and automatically compensates for the heat received by the carton in combination with the carton running speed.

[0053] Specifically, the speed sensor detects the real-time running speed V (packs / minute) of the strip box 6 on the conveyor belt 9. The system uses T0 (°C) as a reference and calculates the target temperature of the hot air, i.e., the actual temperature T (°C) of the hot air received by the transparent paper, according to the following formula:

[0054] T = T0 + 0.15 × (V - 400)

[0055] Where V represents the number of boxes passing through per unit time, it is not the physical linear velocity, but the operating speed measured by the output quantity, used to reflect the current operating speed of the production line.

[0056] The temperature control module then uses this target temperature T as the basis for adjustment, controlling the power of the PTC heater 4 to make the actual hot air temperature reach the target temperature T.

[0057] At the same time, the system will adjust the fan speed according to the actual temperature T. The relationship between the fan speed v (m / s) and the actual temperature T (°C) satisfies the following:

[0058] v = 0.08 × T

[0059] The fan is driven by an EC motor, whose speed can be precisely controlled by PWM signal to ensure that the hot air flow increases synchronously at high temperatures, thereby achieving a heat balance between preheating temperature and blowing time.

[0060] In actual operation, when the running speed of the conveyor belt 9 onto the box 6 increases, the system will automatically increase the heating power of the PTC heater 4, so that the hot air temperature increases with the speed and the fan speed is increased, thereby compensating for the insufficient heat caused by the shortened heating time; conversely, when the running speed of the conveyor belt 9 onto the box 6 decreases, the system will automatically reduce the heating power of the PTC heater 4, so that the hot air temperature decreases with the speed and the fan speed is reduced, thereby compensating for the excessive heat caused by the increased heating time.

[0061] For example, when the running speed of the carton 6 on the conveyor belt 9 is 400 packs / minute, the actual temperature of the hot air received by the transparent paper is the set temperature of 65°C, and the wind speed is 5.2 m / s. At this time, no temperature compensation is required. When the running speed increases to 500 packs / minute, the time that the carton 6 spends passing through the preheating mechanism 1 will decrease. Therefore, the system will automatically increase the power of the PTC heater 4 to raise the actual temperature of the hot air received by the transparent paper to 80°C, and at the same time increase the wind speed to 6.4 m / s to increase the coverage and heat transfer efficiency of the hot air, and compensate for the insufficient heat caused by the shortened preheating time. Similarly, when the running speed decreases to 300 packs / minute, the time that the carton 6 spends passing through the preheating mechanism 1 will increase. Therefore, the system will automatically reduce the power of the PTC heater 4 to reduce the actual temperature of the hot air received by the transparent paper to 50°C, and at the same time reduce the wind speed to 4.0 m / s to compensate for the excessive heat caused by the increased preheating time, and prevent excessive heat accumulation that could lead to overheating or deformation of the transparent paper.

[0062] This control strategy enables the coordinated adjustment of hot air volume and temperature at different operating speeds, which is beneficial for adapting to high-speed and low-speed operating states, improving the equipment's adaptability, and reducing manual intervention.

[0063] Furthermore, the preheating mechanism 1 also includes a temperature control probe, which is located at the center of the bottom of the mounting plate 7, for real-time detection of the temperature of the hot air sprayed onto the surface of the transparent paper. The temperature control probe provides real-time feedback on the hot air temperature, offering monitoring data for backend control and improving the system's temperature control accuracy.

[0064] Furthermore, the temperature control probe is electrically connected to the temperature control module. When the temperature control probe detects that the hot air temperature exceeds the set threshold, the temperature control module controls the heater 4 to stop working. This over-temperature protection mechanism can prevent the heater 4 from operating under overload for a long time, ensuring that the hot air temperature remains stable within a safe range and effectively preventing high-temperature damage to the transparent paper and equipment components. For example, the set threshold can be 85°C.

[0065] The strip-shaped beauty device provided in this application can improve the adhesion of the transparent paper on the surface of the strip box 6 before cosmetic surgery, and enhance the consistency and stability of the appearance quality of the finished package. In addition, the strip-shaped beauty container 5 itself has temperature parameter settings for different machines. Therefore, the strip-shaped beauty device provided in this application is suitable for all soft box models.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
