Description

Technical Field

[0001] This utility model relates to the field of foam box production equipment, specifically a foam box finishing device after molding. Background Technology

[0002] Foam boxes are widely used in logistics, transportation, and food preservation due to their excellent heat insulation, shock absorption, and waterproof properties. However, during the manufacturing process, burrs often form on the edges of the foam boxes due to molding techniques. These burrs not only affect the appearance of the foam box but may also cause inconvenience to users during subsequent use and may even affect key performance indicators such as the box's sealing performance.

[0003] Currently, traditional foam box trimming methods suffer from the following problems: First, many trimming devices use blades to directly cut away the burrs. However, foam boxes are made of foam particles, which are loose and uneven in texture, resulting in fluctuating resistance to the blades. During the cutting process, this uneven resistance easily leads to burrs, cracks, and even breakage of the foam box. This not only reduces the trimming effect but also significantly increases the product breakage rate and production costs. Second, some existing trimming devices have low automation levels, requiring a large amount of manual operation. Manual operation is not only slow but also makes it difficult to ensure consistent trimming quality. Utility Model Content

[0004] In order to overcome some of the problems mentioned in the background above, this invention provides a device for trimming foam boxes after molding.

[0005] The technical solution adopted by this utility model is as follows: a foam box molding and finishing device, including a conveying mechanism, wherein the upper part of the conveying mechanism is provided with a pressing mechanism, a hot melt trimming mechanism and a supporting mechanism; the pressing mechanism is connected to the supporting mechanism, and the hot melt trimming mechanism is connected to the pressing mechanism; The clamping mechanism includes a telescopic rod and a clamping unit. The telescopic rod drives the clamping unit to move, and support plates are provided on both sides of the clamping unit. The hot-melt trimming mechanism includes a connecting plate, an elastic component, and a hot-melt component. The connecting plate is connected to the support plate. The elastic component is disposed between the connecting plate and the hot-melt component. The front end of the hot-melt component is provided with an arc-shaped guide plate, which is used to guide the movement of the box.

[0006] Furthermore, the conveying mechanism includes a drive motor and a conveyor belt, the surface of which is provided with anti-slip texture, and the drive motor is configured to drive the conveyor belt to circulate.

[0007] Furthermore, the end of the support plate passes through the support mechanism and connects to the baffle; The clamping unit includes a fixed frame and multiple clamping wheels. The telescopic rod is connected to the fixed frame and is used to adjust the height of the fixed frame. The clamping wheels are rotatably installed in the fixed frame via a rotating shaft, and their surfaces are made of flexible material.

[0008] Furthermore, the connecting plate and the support plate are fixed together with screws; The hot-melting component also includes a fixing plate and a hot-melting blade. The fixing plate is hinged to the elastic component. The arc-shaped guide plate is connected to the front end of the fixing plate. The hot-melting blade is installed on the side of the fixing plate and connected to the temperature control module via a wire.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0017] like Figures 1-4 As shown, in some embodiments, a foam box finishing device includes a conveying mechanism 1, and a pressing mechanism 2, a hot-melt trimming mechanism 3, and a supporting mechanism 4 are provided on the upper part of the conveying mechanism 1. These mechanisms work together to form a complete finishing operation. The conveying mechanism 1 serves as the foundation and is responsible for the smooth transport of the box body 5. The pressing mechanism 2 is connected to the supporting mechanism 4, and the hot-melt trimming mechanism 3 is connected to the pressing mechanism 2. The clamping mechanism 2 includes a telescopic rod 21 and a clamping unit. The telescopic rod 21 drives the clamping unit to move, and support plates 24 are arranged on both sides of the clamping unit. Specifically, the telescopic rod 21 is connected to the support mechanism 4 and drives the clamping unit to move downward, thus clamping the box 5 and preventing displacement during the trimming process. Support plates 24 are symmetrically arranged on both sides of the clamping unit. These support plates 24 not only provide support but also form an effective connection with the hot melt trimming mechanism 3.

[0018] Two hot-melt trimming mechanisms 3 are provided, located on both sides of the clamping unit, simultaneously trimming both sides of the housing 5. Each hot-melt trimming mechanism 3 includes a connecting plate 31, an elastic component, and a hot-melt component. The connecting plate 31 is bolted to the support plate 24 to ensure structural sturdiness. The elastic component is positioned between the connecting plate 31 and the hot-melt component, serving as a buffer and pressure regulator. A specially designed arc-shaped guide plate 37 is located at the front end of the hot-melt component; its arc structure effectively guides the smooth movement of the housing 5.

[0019] In this embodiment, the principle of hot-melt trimming is that after the hot-melt knife 35 is heated to an appropriate temperature, when it comes into contact with the edge of the foam box, heat conduction causes the foam material in the contact area to rapidly heat up to a molten state. The specific advantages of this hot-melt method are: first, the molten cutting surface is naturally sealed, and no loose particles are produced; second, there is no mechanical stress during the cutting process, avoiding material breakage under pressure; and third, the cutting surface is smooth and flat, requiring no secondary processing.

[0020] It is worth noting that in this embodiment, by employing a hot-melt trimming method, the temperature of the hot-melt knife 35 is precisely controlled, and the heat is used to melt the burrs, avoiding the mechanical stress on the box body 5 caused by traditional cutting tools. At the same time, the elastic component of the hot-melt knife 35 provides elastic cushioning, further reducing the impact on the box body 5, thus significantly reducing the breakage rate of the foam box during the trimming process.

[0021] The conveying mechanism 1 enables continuous and stable conveying, while the pressing mechanism 2 and the hot melt trimming mechanism 3 work together to quickly complete the pressing and trimming operations, greatly improving production efficiency.

[0022] Furthermore, in some embodiments, the conveying mechanism 1 includes a drive motor 11 and a conveyor belt 12. The drive motor 11 serves as a power source, connected to the conveyor belt 12 via a transmission device, providing it with a stable and reliable driving force. The surface of the conveyor belt 12 is uniformly distributed with anti-slip textures, which effectively prevent the box 5 from slipping or shifting during conveying by increasing the coefficient of friction. The components of the entire conveying mechanism 1 are tightly fitted together, ensuring the smooth conveying of the box 5 during the trimming process.

[0023] Furthermore, in some embodiments, the end of the support plate 24 extends horizontally and completely penetrates the side wall of the support mechanism 4, and is finally fixedly connected to the baffle 25. This structural design can ensure that the support plate 24 maintains a smooth movement effect during operation.

[0024] The clamping unit consists of a fixed frame 22 and multiple evenly distributed clamping rollers 23. The end of the telescopic rod 21 is fixedly connected to the center of the fixed frame 22. The height of the fixed frame 22 relative to the surface of the foam box can be adjusted by the lifting and lowering movement of the telescopic rod 21. Each clamping roller 23 is rotatably installed in the internal frame of the fixed frame 22 via a high-precision rotating shaft. The surface of all clamping rollers 23 is covered with a highly elastic and wear-resistant flexible material. This design can ensure uniform pressure on the surface of the foam box and effectively avoid damage to the surface of the foam box during the trimming process.

[0025] Furthermore, in some embodiments, the connecting plate 31 and the support plate 24 are fixedly connected by screws. Specifically, the position of the connecting plate 31 is adjusted according to the size of the box 5, and the connecting plate 31 is connected by screws so that the hot melt knife 35 can better contact the side of the box 5 to achieve the trimming treatment of the side of the box 5.

[0026] The hot-melt component also includes a fixing plate 34 and a hot-melt blade 35. The fixing plate 34 is made of heat-insulating material. The fixing plate 34 is connected to the elastic component by a hinge, ensuring that the hot-melt component can flexibly adjust its angle during operation. An arc-shaped guide plate 37 is welded and fixed to the front end of the fixing plate 34 to guide the trimming path of the foam box. The hot-melt blade 35 is fastened to the side of the fixing plate 34 and is electrically connected to the temperature control module through wires. The temperature control module adopts an intelligent temperature control system, which is precisely installed on the upper part of the support frame and can adjust the working temperature of the hot-melt blade 35 in real time.

[0027] Specifically, partitions 36 are provided at the upper and lower ends of the hot melt knife 35. The partitions 36 are connected to the fixed plate 34. The cutting edge of the hot melt knife 35 extends out of the partitions 36 to cut off the burrs on the box body 5.

[0028] The elastic component consists of a damping rod 33 and a spring 32. The two work together to effectively absorb the impact force during operation, ensure the smoothness of the trimming process, and enable the hot melt knife 35 to always be in close contact with the side of the housing 5.

[0029] Furthermore, in some embodiments, the support mechanism 4 includes a support side plate 41, a support top plate 42, and a slide rail 43. The support side plate 41 and the support top plate 42 form a frame structure, providing stable support for the clamping mechanism 2. The slide rail 43 is disposed on the support side plate 41, and the support plate 24 can move up and down along the slide rail 43, thereby realizing the clamping operation on the housing 5.

[0030] Furthermore, the slide rail 43 is compatible with foam boxes of different heights from 300-600mm, allowing the pressing mechanism 2 and the hot-melt trimming mechanism 3 to be precisely adjusted according to the height of the box body 5. This slide rail adjustment mechanism enables the pressing mechanism 2 and the hot-melt trimming mechanism 3 to be precisely matched in height and adjusted in position according to foam box products of different heights, thereby ensuring that the entire trimming process can achieve the optimal processing effect for foam box bodies 5 of different sizes.

[0031] The specific operation process of this embodiment is as follows: The molded foam box 5 is placed on the conveying mechanism 1. The conveyor belt 12 with anti-slip texture is driven by the drive motor 11 to convey the foam box 5 to the trimming area at a constant speed.

[0032] The telescopic rod 21 in the clamping mechanism 2 drives the clamping unit to descend to a preset height. After the clamping wheel 23 contacts the upper surface of the box 5, it continues to apply constant pressure to stably fix the box 5 on the conveyor belt 12, preventing displacement or vibration during the trimming process.

[0033] Meanwhile, the hot melt knife 35 is heated to the set temperature and maintained at a constant temperature. The box 5 continues to move forward under the drive of the conveyor belt 12, and its edge first contacts the arc-shaped guide plate 37 of the hot melt trimming mechanism 3. The arc design allows the box 5 to smoothly enter the trimming position without the need for additional guiding devices.

[0034] When the edge of the housing 5 reaches the position of the hot melt knife 35, the hot melt trimming process officially begins. The hot melt knife 35 contacts the edge of the housing 5 at a constant temperature, removing the burrs through hot melting.

[0035] After one side is trimmed, the box 5 continues to move forward and exits from the conveyor belt 12.
