Description

Technical Field

[0001] The utility model relates to the technical field of EPP product production, in particular to a blowing device for an EPP product workshop. Background Technique

[0002] Expanded polypropylene (EPP), as a high-performance lightweight foam material, is widely used in fields such as automotive parts, packaging materials, and building insulation due to its unique physical and mechanical properties, such as good energy absorption capacity, durability, heat resistance, and excellent chemical stability. After being formed, EPP products usually need to be dried to remove excess moisture or solvents in the products to ensure the stability and quality of the products.

[0003] Most of the existing drying methods in EPP product workshops use hot air blowing in a single direction. This method not only has low efficiency but also uneven drying effect. That is, the parts close to the air outlet dry faster due to directly receiving hot air, while the parts far from the air outlet dry slower due to less hot air reaching. This difference leads to unstable product quality. Especially when processing multi-layer EPP foam products, this drying method often results in insufficient drying of the products at the bottom layer or inside, while the products on the surface may have quality problems such as cracks due to over-drying, seriously affecting the quality and performance of the final products. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a blowing device for an EPP product workshop to solve the problems in the above background technique that the single-direction hot air blowing method currently used in EPP product workshops has low efficiency and uneven drying, resulting in too fast drying of the parts close to the air outlet and too slow drying of the parts far from the air outlet, especially affecting the quality and performance of multi-layer EPP foam products.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A blowing device for an EPP product workshop, including a workshop suspension plate. One side of the top of the workshop suspension plate is equipped with a blower. The bottom of the workshop suspension plate is provided with a horizontally distributed air duct. An external connecting pipe is connected between the middle of the air duct and the air outlet end of the blower. And a plurality of hollow air outlet plates are evenly arranged at the bottom of the air duct. The top ends of the air outlet plates are connected to the air duct through hoses. Linking shafts are connected between the corresponding sides of the top ends of the air outlet plates. And a vertical support is arranged on one side of the workshop suspension plate. A regulating mechanism for driving the plurality of air outlet plates to tilt left and right is arranged on the vertical support.

[0006] Preferably, the adjustment mechanism on the vertical support includes a hydraulic cylinder, a lifting block, and a pulling shaft. The hydraulic cylinder is fixed at the upper end of the vertical support. The lifting block is fixed at the output end of the hydraulic cylinder and is slidably connected to the vertical support. The pulling shaft is connected between the lifting block and a corresponding air outlet plate.

[0007] Preferably, a plurality of air outlets are evenly provided at the front end of the air outlet plate. An end cover is hinged outside the air outlet, and arc-shaped guide blocks are symmetrically provided on the inner wall of the air outlet.

[0008] Preferably, suspension rods are inserted through both sides of the workshop suspension plate, and the connection between the workshop suspension plate and the suspension rods is fixedly connected by fastening screws.

[0009] Preferably, guide columns are symmetrically provided on the vertical support through notches, and guide sleeves sleeved outside the guide columns are symmetrically provided on the back side of the lifting block.

[0010] Preferably, the top end of the air outlet plate and the bottom of the air duct are movably connected through a rotating pin.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The blowing device in the EPP product workshop can achieve efficient and uniform drying of multi-layer EPP foam products, not only significantly improving production efficiency but also effectively avoiding quality problems that may occur in traditional drying methods. The hot air generated by the blower first enters the air duct through the external connecting pipe, and then is evenly distributed to each air outlet plate through the hose. By combining the movable connection between the air outlet plate and the air duct, the inclination angle of the air outlet plate can be flexibly adjusted through the linkage shaft and the adjustment mechanism. In this way, when drying multi-layer EPP foam products, the hot air can more evenly cover the sides of EPP foam products at different levels. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a blowing device for an EPP product workshop, which includes a workshop suspension plate 1. On one side of the top of the workshop suspension plate 1, a blower 2 is installed. At the bottom of the workshop suspension plate 1, there is a horizontally distributed air duct 4. Between the middle of the air duct 4 and the air outlet end of the blower 2, an external connecting pipe 3 is connected. And at the bottom of the air duct 4, a number of air outlet plates 5 with a hollow structure are evenly arranged. The top ends of the air outlet plates 5 and the bottom of the air duct 4 are both movably connected by a rotating pin. The top ends of the air outlet plates 5 and the air duct 4 are connected by a hose 6. Between the corresponding sides of the top ends of the air outlet plates 5, a linkage shaft 7 is connected. The connection between the linkage shaft 7 and the air outlet plates 5 is hinged by a pin shaft. And on one side of the workshop suspension plate 1, a vertical bracket 9 is fixed by bolts. On the vertical bracket 9, there is a regulating mechanism for driving a number of air outlet plates 5 to tilt left and right. In this structure, the hot air generated by the blower 2 is first sent into the air duct 4 through the external connecting pipe 3, and then evenly distributed to each air outlet plate 5 through the hose 6. And because the air outlet plates 5 and the air duct 4 are movably connected, in this way, the left and right tilting angles of the air outlet plates 5 can be flexibly adjusted through the linkage shaft 7 and the regulating mechanism. That is, when drying multi-layer EPP foam products, the tilting angle of the air outlet plates 5 is adjusted through the regulating mechanism, so that the hot air can more evenly cover the sides of different layers of EPP foam products. As the air outlet plates 5 tilt left and right, the hot air can more effectively penetrate the gaps between multi-layer EPP foam products, ensuring that each layer of products can obtain consistent drying conditions, thus avoiding insufficient drying of the products at the bottom or inside, and at the same time preventing quality problems such as cracks in the surface products due to excessive drying. Furthermore, this device not only significantly improves the drying efficiency, but also effectively avoids the quality problems that may occur in traditional drying methods, improving the quality and performance of the final product. The regulating mechanism on the vertical bracket 9 includes a hydraulic cylinder 10, a lifting block 11 and a pulling shaft 12. The hydraulic cylinder 10 is fixedly installed at the upper end of the vertical bracket 9 by bolts. The lifting block 11 is welded and fixed at the output end of the hydraulic cylinder 10 and is slidably connected with the vertical bracket 9. The pulling shaft 12 is connected between the lifting block 11 and a corresponding air outlet plate 5. The connections between the pulling shaft 12 and the lifting block 11 and one of the air outlet plates 5 are also hinged by a pin shaft. In this structure, the hydraulic cylinder 10 pushes the lifting block 11 to slide up and down along the vertical bracket 9 through its output end. The movement of the lifting block 11 is transmitted to an air outlet plate 5 hinged to it through the pulling shaft 12, thereby driving all the air outlet plates 5 to tilt left and right. At the front end of the air outlet plate 5, a number of air outlets 51 are evenly arranged. And at the outside of the air outlets 51, an end cover 52 is hinged. And at the inner wall of the air outlets 51, arc-shaped guide blocks are symmetrically arranged. In this structure, the operator can control the air outlet degree of each air outlet plate 5 by covering the end cover 52 at the air outlet 51 according to needs, so as to adjust the hot air flow. And the guide blocks on the inner part of the air outlets 51 help to guide the hot air to form a more uniform air flow distribution, ensuring that the hot air can more evenly cover the sides of different layers of EPP foam products.On both sides of the workshop hanging plate 1, there are inserted suspension rods 8. The top ends of the suspension rods 8 are pre-fixed on the top wall of the workshop. And the connection between the workshop hanging plate 1 and the suspension rods 8 is fixedly connected by fastening screws. Operators of this structure can adjust the relative position between the suspension rods 8 and the workshop hanging plate 1 by loosening or tightening the fastening screws, thereby adjusting the height of the entire blowing device to meet the drying requirements of multi-layer EPP foam products at different heights. This enables the device to more flexibly adapt to different production scenarios. On the vertical support 9, guide posts 13 are symmetrically arranged through notches. And on the back side of the lifting block 11, guide sleeves 14 sleeved outside the guide posts 13 are symmetrically welded and fixed. In this structure, when the hydraulic cylinder 10 drives the lifting block 11 to move up and down, the guide sleeve 14 can slide along the guide post 13, ensuring the smooth movement of the lifting block 11.,

[0018] Working principle: When using the blowing device in the EPP product workshop, first, adjust the relative position between the suspension rods 8 and the workshop hanging plate 1 by loosening or tightening the fastening screws, thereby adjusting the height of the entire blowing device to meet the drying requirements of multi-layer EPP foam products at different heights. Then, the hot air generated by the blower 2 is sent into the air duct 4 through the external connecting pipe 3, and then evenly distributed to each air outlet plate 5 through the hose 6. At this time, the hydraulic cylinder 10 pushes the lifting block 11 to slide up and down along the vertical support 9 through its output end. When the lifting block 11 moves up and down, it drives the guide sleeve 14 to slide along the guide post 13. The movement of the lifting block 11 is synchronously transmitted to one air outlet plate 5 hinged to it through the pulling shaft 12, thereby driving all the air outlet plates 5 to tilt left and right. Operators can also control the air outlet degree of each air outlet plate 5 by covering the end cover 52 on the air outlet 51 as needed. As the air outlet plates 5 tilt left and right, the hot air can more effectively penetrate the gaps between multi-layer EPP foam products, ensuring that each layer of products can obtain consistent drying conditions, thus completing a series of operations.

[0019] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
