Description

Technical Field

[0001] The utility model relates to the technical field of engineering plastic production equipment, in particular to an air drying device for plastic production. Background Art

[0002] In the plastic production process, the plastic is extruded into strip-shaped plastic strips by an extruder and generally needs to be air-dried. The air-drying process usually involves cooling in a water tank and then using an air-drying device to remove the moisture on the plastic strips.

[0003] The air-drying device generally includes a blower, an air outlet hood and a water receiving tank. The air outlet hood is used to limit the air outlet range, and the water receiving tank is used to collect the blown-off water. However, in the existing air-drying devices, the air outlet hood and the water receiving tank are generally standard parts and cannot be adjusted in length during the working process after leaving the factory. Different diameters and material ratios of plastic strips require different air volumes and air outlet ranges. Since the existing air-drying devices cannot be adapted to change different air volumes and different air outlet ranges, only the air outlet hood and the water receiving tank can be replaced. It is necessary to purchase multiple types of air outlet hoods and water receiving tanks, which is not only troublesome to replace and takes up space, but also increases the production cost. Therefore, the existing air-drying devices have problems such as low adaptability, cumbersome replacement operations resulting in low work efficiency, and high production costs.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0044] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0045] As Figure 1 - Figure 4 As shown, an air-drying device 1 for plastic production provided by the present application includes a blower 10 and an air outlet cover 30. The blower 10 is connected to the air outlet cover 30 through an air duct. The air outlet cover 30 includes a first cover body 31 and a second cover body 32. One side of the first cover body 31 and the second cover body 32 that are close to each other is rotatably connected, and the first cover body 31 and the second cover body 32 rotate to drive the other side that is away from each other to approach or move away; a water receiving tank body 50, the water receiving tank body 50 is arranged below the air outlet cover 30, and an opening 51 is formed in the side wall of the water receiving tank body 50 along the length direction; an extension part 70, the extension part 70 is movably connected to the opening 51 and communicates with the water receiving tank body 50, and the extension part 70 extends into or out of the opening 51 to increase or decrease the length of the water receiving tank body 50.

[0046] The present application aims to provide an efficient and flexible air-drying device for plastic production. The core components of the device include a blower 10 and an air outlet cover 30. The air outlet cover 30 is closely connected to the blower 10 through an air duct to ensure the stable and efficient transmission of wind power. The air outlet cover 30 consists of two parts: a first cover body 31 and a second cover body 32. These two parts are closely connected by a rotating connection method on the side close to each other. Users can easily adjust the relative positions of the first cover body 31 and the second cover body 32 through rotation operations, so that the other side edges of them approach or move away to adapt to plastic products of different sizes and shapes or plastic products with different air-drying effects.

[0047] In addition, the device is also equipped with a water receiving tank body 50, which is arranged below the air outlet hood 30 to facilitate the collection of moisture generated during the air drying process. The design of the water receiving tank body 50 also reflects practicality. An opening 51 is provided on the side wall along its length direction, and this opening 51 allows users to adjust according to their needs. Through an extension piece 70 movably connected to the opening 51, users can easily extend or retract the extension piece 70 into or out of the opening 51, thereby increasing or decreasing the length of the water receiving tank body 50 to adapt to different production environments and requirements. It can be understood that users can adjust the lengths of the air outlet hood 30 and the water receiving tank body 50 to be the same length, or the length of the water receiving tank body 50 is slightly greater than that of the air outlet hood 30 to ensure the water receiving effect of the water receiving tank body 50.

[0048] In summary, the air drying device for plastic production provided by this application not only has an efficient air drying effect but also has flexible adjustment capabilities, capable of meeting the diverse needs of different users.

[0049] Furthermore, the air drying device for plastic production is also provided with an intelligent control system: integrating advanced sensors and control systems to achieve automatic adjustment of air volume and wind speed. According to the material, size, and shape of plastic products, the system can intelligently identify and adjust the optimal air drying parameters to ensure the maximization of air drying effect and efficiency.

[0050] Furthermore, the air drying device for plastic production is also provided with a temperature adjustment function: integrating heating elements in the air outlet hood 30 or the air duct, allowing users to adjust the temperature during the air drying process according to their needs. This can not only accelerate water evaporation but also preheat or post-treat plastic products in some cases.

[0051] Furthermore, the air drying device for plastic production is also provided with a noise suppression design: by using low-noise fans, sound insulation materials, and optimizing the structural design, the noise generated during the operation of the device is reduced, improving the comfort of the working environment.

[0052] Furthermore, the air drying device for plastic production is also provided with a moving and fixing structure: designing a movable base or bracket, enabling the air drying device to move easily between different working areas. At the same time, fixed installation options are also provided to meet the needs of long-term fixed use.

[0053] Furthermore, the air drying device for plastic production is also provided with a safety protection mechanism: integrating safety mechanisms such as overheat protection and overload protection to ensure that the device can automatically shut down in case of abnormalities, preventing equipment damage or personnel injury.

[0054] Furthermore, the air-drying device for plastic production also adopts an environmentally friendly and energy-saving design: it uses highly efficient and energy-saving fans and heating elements to reduce energy consumption. At the same time, the structural design and material selection are optimized to ensure that the device has low maintenance costs and a long service life during long-term use.

[0055] To enhance the air-drying effect and ensure uniform air-drying of plastic products, multiple layers of air guide plates can be arranged inside the first cover body 31 and the second cover body 32. These air guide plates are arranged at specific angles and intervals, which can not only effectively guide the flow direction of the air flow, but also enhance the diffusion range of the air flow, ensuring that the air generated by the air outlet cover 30 can evenly cover the plastic products.

[0056] In addition, to improve the usability of the water receiving tank body 50, a water level sensor and an automatic drainage device are also arranged inside it. The water level sensor can monitor the water level in the water receiving tank body 50 in real time. When the water level reaches the preset threshold, the automatic drainage device will be automatically activated to drain the accumulated water. This design not only greatly reduces the workload of users, but also avoids problems such as equipment damage or performance degradation caused by excessive accumulated water.

[0057] Finally, we have also optimized the design of the extension piece 70. The extension piece 70 adopts a telescopic design, and users can adjust its length according to needs to adapt to plastic products of different sizes and shapes. At the same time, the extension piece 70 is made of waterproof materials to ensure that it will not be eroded by moisture during use.

[0058] The above technical solutions provided by the embodiments of the present application have the following advantages compared with the prior art: through the relative rotation of the first cover body 31 and the second cover body 32 of the air outlet cover 30 of the present application, the overall air outlet area of the air outlet cover 30 can be increased or decreased along the length direction. The water receiving tank body 50 is movably connected to the opening 51 through the extension piece 70 and can extend into or out of the opening 51, so that the overall accommodation space of the water receiving tank body 50 can be increased or shortened. Furthermore, both the air outlet cover 30 and the water receiving tank can be increased or decreased in length, realizing the free and rapid adjustment of the lengths of the air outlet cover 30 and the water receiving tank, without changing the air outlet cover 30 and the water receiving tank, with high adaptability, simple operation, improved work efficiency, and reduced production costs.

[0059] Such as Figure 1 - Figure 4As shown in the figure, a drying device 1 for plastic production provided by the present application includes a blower 10 and an air outlet hood 30. The blower 10 is connected to the air outlet hood 30 through an air duct. The air outlet hood 30 includes a first hood body 31 and a second hood body 32. One side of the first hood body 31 and the second hood body 32 that are close to each other is rotatably connected. The first hood body 31 and the second hood body 32 rotate to drive the sides away from each other to approach or move away; a water receiving tank body 50 is arranged below the air outlet hood 30. An opening 51 is formed in the side wall of the water receiving tank body 50 along the length direction; an extension member 70 is movably connected to the opening 51 and communicates with the water receiving tank body 50. The extension member 70 extends into or out of the opening 51 to increase or decrease the length of the water receiving tank body 50.

[0060] Further, the air outlet hood 30 further includes a rotating shaft 33 and a knob 34. One side of the first hood body 31 and the second hood body 32 facing each other is connected to the rotating shaft 33. The knob 34 is connected to the end of the rotating shaft 33. Rotating the knob 34 drives the connecting shaft 36 to rotate, and drives the other sides of the first hood body 31 and the second hood body 32 to approach or move away from each other.

[0061] One side of the first hood body 31 and the second hood body 32 facing each other is tightly connected to the rotating shaft 33. This structure ensures the overall stability and flexibility. The knob 34 is cleverly installed at the end of the rotating shaft 33. With a gentle rotation by the user, the entire connecting shaft 36 can be driven to rotate smoothly. As the knob 34 rotates, the other sides of the first hood body 31 and the second hood body 32 can approach or separate to open or close the air outlet hood 30, thereby changing the length of the air outlet hood 30. Further, the first hood body 31 and the second hood body 32 are connected to the rotating shaft 33 in an alternating position. By rotating the rotating shaft 33, the first hood body 31 and the second hood body 32 can rotate synchronously to achieve the effect of simultaneous opening and closing.

[0062] Further, the rotating shaft 33 is made of a high-strength alloy material, ensuring the stability and durability during long-term use. At the same time, the surface of the rotating shaft 33 is specially treated, smooth and wear-resistant, effectively reducing the noise generated by friction and providing a quieter use environment for users.

[0063] Further, the surface of the knob 34 is designed with anti-slip texture, enabling easy operation even in a wet and slippery environment. The rotational damping of the knob 34 is carefully adjusted to ensure the smoothness of the operation and avoid accidental situations caused by too fast operation.

[0064] When the knob 34 is rotated, the rotating shaft 33 will rotate accordingly, thereby driving the other sides of the first cover 31 and the second cover 32 to approach or move away from each other. This design enables the air outlet cover 30 to easily adapt to air outlets of different sizes, providing users with more flexible usage options. At the same time, the sealing performance between the first cover 31 and the second cover 32 has been significantly improved, effectively reducing air volume leakage and enhancing the air outlet efficiency.

[0065] Furthermore, the air outlet cover 30 further includes two baffles 35. The two baffles 35 are respectively movably connected to the outer walls of the first cover 31 and the second cover 32, and the baffles 35 are moved or rotated to protrude from the side edges of the first cover 31 or the second cover 32 that face away from each other. These two baffles 35 are added to enhance the flexibility and practicality of the air outlet cover 30. The two baffles 35 are made of high-strength materials to ensure stable operation even in harsh environments.

[0066] When the direction of the air outlet needs to be adjusted, the user only needs to simply move or rotate the baffle 35 to make it protrude from the side edge of the first cover 31 or the second cover 32 that faces away from each other. In this way, the air outlet blocking edges on the two sides of the first cover 31 or the second cover 32 that face away from each other can be extended, thereby achieving the best air outlet direction and air outlet intensity of the air outlet cover 30.

[0067] In addition to adjusting the air outlet direction, the two baffles 35 also have the function of preventing dust and debris from entering the interior of the air outlet cover 30. When the baffles 35 are closed, they can closely fit on the cover body to form a complete sealing surface. In this way, even if there is a large amount of dust and debris in the working environment, they can be effectively blocked outside the air outlet cover 30 to ensure the normal operation of the internal equipment. In addition, the two baffles 35 also have the characteristic of being easy to clean. The user only needs to regularly remove the baffles 35 and rinse them with clean water. This not only facilitates the maintenance work of the user but also extends the service life of the air outlet cover 30.

[0068] Furthermore, the air outlet cover 30 further includes a connecting shaft 36. The connecting shaft 36 is connected to the outer wall of the first cover 31 or the second cover 32, and the baffle 35 is rotatably connected to the connecting shaft 36.

[0069] In the delicate design of the air outlet cover 30, the connecting shaft 36, as one of the core components, not only plays a role in connecting the outer walls of the first cover 31 or the second cover 32 but also plays a key role in the rotational adjustment of the baffle 35. The connecting shaft 36 is made of high-strength alloy material to ensure its stability and durability. Even in a long-term high-load working state, it can maintain excellent mechanical properties.

[0070] The rotational connection design of the baffle 35 enables users to freely adjust the opening degree of the air outlet according to their needs, thereby achieving precise control of the air outlet. A precise bearing and sealing structure is adopted between the baffle 35 and the connecting shaft 36 to ensure smooth rotation without obstruction, while preventing the intrusion of dust and foreign objects, ensuring the cleanliness and hygiene of the internal environment of the air outlet cover 30.

[0071] When it is necessary to increase the air outlet, the user only needs to gently rotate the baffle 35 to move it away from the center of the air outlet cover 30, thereby increasing the area of the air outlet and making the air circulation smoother. Conversely, when it is necessary to reduce the air outlet, only rotate the baffle 35 towards the center of the air outlet cover 30 to reduce the area of the air outlet and achieve precise control of the air volume.

[0072] Furthermore, a damping member is provided inside the connecting shaft 36; the damping member provided inside the connecting shaft 36 plays a crucial role in mechanical operation. This damping member can not only effectively reduce vibration and noise, but also improve the stability and durability of the entire mechanical system. The connection shaft 36 is provided with a damping member, which can also achieve the effect of the baffle 35 hovering, enabling the baffle 35 to rotate to any position and stop, maintaining the rotational position of the baffle 35.

[0073] The damping member is usually made of highly elastic materials such as rubber, plastic or special metal alloys, and these materials all have excellent shock absorption and damping performance. When the connecting shaft 36 rotates or moves, the damping member can absorb the energy generated by mechanical movement and convert it into heat energy or other forms of energy, thereby reducing the impact and vibration inside the mechanical system.

[0074] In addition to the shock absorption and damping functions, the damping member can also form a certain damping force between the connecting shaft 36 and other components. This damping force can balance the dynamic load in the mechanical system and reduce the stress and deformation caused by load changes. Therefore, the presence of the damping member can significantly extend the service life of the mechanical system and improve the reliability of the equipment.

[0075] And / or, the air outlet cover 30 further includes a clamping member 37, and the clamping member 37 is rotationally connected to the outer wall of the first cover body 31 or the second cover body 32. The clamping member 37 rotates to clamp or disengage from the upwardly moving baffle 35. The clamping member 37 can be a baffle, a buckle, a clip, etc. When the baffle 35 rotates to a position close to the first cover body 31 or the second cover body 32, that is, in the storage position, the clamping member 37 can be rotated to abut against the outside of the baffle 35 to press against the baffle 35 to prevent it from rotating downward, restricting the rotation of the baffle 35 and maintaining its position, achieving the storage effect.

[0076] Such as Figure 1 - Figure 5As shown in the figure, a drying device 1 for plastic production provided by the present application includes a blower 10 and an air outlet hood 30. The blower 10 is connected to the air outlet hood 30 through an air duct. The air outlet hood 30 includes a first hood body 31 and a second hood body 32. One side of the first hood body 31 and the second hood body 32 that are close to each other is rotatably connected, and the first hood body 31 and the second hood body 32 rotate to drive the sides away from each other to approach or move away; a water receiving tank body 50 is arranged below the air outlet hood 30, and an opening 51 is formed in the side wall of the water receiving tank body 50 along the length direction; an extension member 70 is movably connected to the opening 51 and communicates with the water receiving tank body 50. The extension member 70 extends into or out of the opening 51 to increase or decrease the length of the water receiving tank body 50.

[0077] Further, the extension member 70 includes a cover plate 71, a bottom plate 72 and two side plates 73. The cover plate 71 covers the side wall opening 51 of the water receiving tank body 50. The two side plates 73 are respectively connected to the horizontal two sides of the cover plate 71 and extend along the extending direction of the water receiving tank body 50. The bottom plate 72 is rotatably connected to the bottom edge of the cover plate 71 and abuts against the edge of the opening 51. The extension member 70 is jointly composed of the cover plate 71, the bottom plate 72 and the symmetric side plates 73 on both sides. Among them, the cover plate 71 is cleverly attached to the side wall opening 51 of the water receiving tank body 50 to form a tight closed structure. The two side plates 73 are accurately connected to the horizontal two sides of the cover plate 71 and cleverly extend along the extending direction of the water receiving tank body 50, enhancing the stability and reliability of the entire extension member 70. The bottom plate 72 is tightly connected to the bottom edge of the cover plate 71 through a clever rotation mechanism and tightly fits against the edge of the opening 51 at the same time, ensuring the smooth flow of water and the effect of preventing leakage. Such a design ensures the practicability and durability of the extension member 70.

[0078] Further, a chute 711 is arranged in the cover plate 71. The extension member 70 further includes a movable shaft 74. The movable shaft 74 is movably arranged in the chute 711. One side edge of the bottom plate 72 is rotatably connected to the movable shaft 74. The bottom plate 72 extends into or out of the opening 51 to drive the movable shaft 74 to move in the chute 711. Both ends of the movable shaft 74 are connected to the inner side wall of the chute 711, so that the movable shaft 74 can move in the chute 711. Furthermore, when the bottom plate 72 abuts against the edge of the opening 51 and flips along the edge of the opening 51, correspondingly, the movable shaft 74 can move along the chute 711, realizing the way of flipping the bottom plate 72 to open and close, and keeping the bottom plate 72 always abutting against the edge of the opening 51.

[0079] Further, the water receiving tank body 50 further includes a plurality of seals 53. The seals 53 are provided at the edge of the opening 51 and are located between the water receiving tank body 50 and the side plate 73 or the bottom plate 72. The seals 53 can be gaskets, sealants, sealing rings, etc. By providing the seals 53 between the water receiving tank body 50 and the side plate 73 or the bottom plate 72, on the one hand, it can prevent the water in the water receiving tank from leaking out, and on the other hand, it can prevent external dust and contaminated liquids from entering the inside of the water receiving tank body 50, achieving internal and external isolation and ensuring the independence of the inside of the water receiving tank body 50.
