[0034] In order to further illustrate the technical means and effects of the utility model for realizing the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows by combining with the drawings and preferred embodiments.
[0035] Please refer to Figures 1-9As shown, the purpose of the present embodiment is to provide a material strip drying equipment, which comprises a drying box 1 for conveying material strip 2, a plurality of rotating rollers 5 are arranged in the drying box 1, a suction box 3 for negative pressure suction is arranged at the bottom of the drying box 1, a plurality of suction pipes 4 are fixedly connected to the suction box 3, a plurality of sealing blocks 9 are fixedly arranged at both ends of the drying box 1, the material strip 2 penetrates the sealing blocks 9 at both ends, a water scraping plate 6 for scraping the surface of the material strip 2 is fixedly arranged at the input end of the drying box 1, and the water scraping plate 6 is located outside the concentric position of the sealing block 9, and a plurality of groups of flow guide plates are fixedly arranged in the drying box 1.
[0036] The material strip drying equipment uses negative pressure suction to blow dry the material strip 2 to be cut, and the negative pressure suction can suck the moisture on the surface of the material strip 2 downward, ensuring the stability and quality of the material strip 2 in subsequent processing.
[0037] A plurality of ring grooves 51 for positioning are formed in the rotating roller 5, the width of the ring groove 51 is greater than the diameter of the material strip 2, and in the conveying process, the material strip 2 is placed in the ring groove 51. Since the width of the ring groove 51 is greater than the diameter of the material strip 2, the material strip 2 can move in the groove without slipping out, ensuring the stability of the material strip 2 in the conveying process and avoiding the problem of misalignment of the output port due to deviation. The ring groove 51 not only provides stable support for the material strip 2, but also plays a certain guiding role. With the rotation of the rotating roller 5, the material strip 2 is stably conveyed along the path of the ring groove 51 to the output end of the drying box 1.
[0038] A plurality of suction ports 11 are formed in the bottom of the drying box 1, and the suction ports 11 are located between the adjacent two rotating rollers 5, ensuring that the bottom and both sides of the material strip 2 can be uniformly and effectively suction dried during the conveying process. The other end of the suction pipe 4 is fixedly connected to the suction port 11, and the width of the suction pipe 4 gradually decreases from one end to the other end, which can increase the suction speed and improve the suction efficiency. The suction port 11 serves as the inlet for negative pressure suction, and through the connection of the suction pipe 4, the air (carrying the moisture on the surface of the material strip 2) in the drying box 1 is sucked into the suction box 3.
[0039] A mesh plate 41 is fixedly arranged at one end of the suction pipe 4, and the mesh plate 41 is used to uniformly absorb the moisture on the material strip 2. The diamond-shaped grid is formed in the mesh plate 41 to ensure that the moisture can be uniformly absorbed and discharged. The design of the diamond-shaped grid not only improves the air permeability and suction efficiency of the mesh plate 41, but also enables the airflow to maintain a certain stability and uniformity when passing through.
[0040] The two ends of the drying box 1 are provided with a plurality of grooves 12, and the sealing block 9 is fixedly arranged in the grooves 12. The sealing block 9 comprises a fixed frame 91 fixedly connected with the inner wall of the groove 12, a plurality of elastic plates 92 are fixedly arranged in the fixed frame 91, and a cross groove 921 is arranged at the center of each elastic plate 92. The two ends of the material strip 2 penetrate the cross grooves 921. The design of the cross grooves 921 allows the material strip 2 to smoothly penetrate, and effectively blocks the intrusion of external air, avoiding affecting the negative pressure effect. When the material strip 2 penetrates the cross grooves 921, due to the unique shape and the shrinkage of the elastic plates 92, the elastic plates 92 will be slightly pushed to the surrounding by the material strip 2. This dynamic adjustment not only ensures the continuity of sealing, but also ensures that the material strip 2 will not be subjected to excessive resistance in the advancing process. In fact, although the elastic plates 92 will be in contact with the surface of the material strip 2, the friction between them is controlled at a very low level, so as not to cause any substantial hindrance to the advancement of the material strip 2.
[0041] The input end of the drying box 1 is provided with a plurality of insertion slots 13, which are inverted U-shaped. One end of the water scraping plate 6 penetrates the insertion slot 13 and is arranged in the drying box 1. Since the material strip enters the dryer after passing through the water of the discharging machine, a large amount of water will remain on the surface of the material strip. In order to promote the drying efficiency of the surface, the water scraping plate 6 is arranged, and the inner wall of the one end of the water scraping plate 6 located in the drying box 1 is provided with dense bristles. As the material strip gradually penetrates into the drying box, the dense bristles on the water scraping plate 6 will contact and scrape most of the water on the surface of the material strip, greatly reducing the moisture content on the surface of the material strip. Through the preliminary scraping of the water, the remaining water is more easily taken away by the negative pressure suction system, so that the whole drying process is more smooth and efficient. In order to ensure the stability of the water scraping plate 6 in the insertion slot 13 and avoid displacement, a plurality of bolts are screwedly arranged on the drying box 1, and one end of the bolt can tightly abut against the water scraping plate 6 to prevent it from slipping or loosening during the working process. This design not only enhances the stability of the water scraping plate 6, but also ensures the continuity and safety of the whole drying process.
[0042] A through hole 61 is arranged through the water scraping plate 6, and the diameter of the through hole 61 is greater than the diameter of the material strip 2, so as to ensure that the material strip can pass through the water scraping plate 6 without any obstruction during the input process, and the smoothness of the advancement will not be affected due to the friction or collision with the water scraping plate 6.
[0043] The both sides of the drying box 1 are provided with a plurality of fixed grooves 14, and elastic blocks 52 are fixedly arranged in the fixed grooves 14, rotating grooves 521 are arranged in the center of the elastic blocks 52, and the both ends of the rotating roller 5 are rotatably arranged in the rotating grooves 521, so that the rotating roller 5 can float within a certain range due to the elasticity and recovery ability of the elastic blocks 52, the floating mechanism is very flexible, and the rotating roller 5 can be self-adaptively adjusted according to the size and weight of the material strip 2, so that the adaptability of the drying box 1 to the material strip 2 is improved, and the stability and smoothness of the material strip 2 in the conveying process are ensured; no matter how the size and weight of the material strip 2 change, the rotating roller 5 can be self-adaptively adjusted through the floating mechanism of the elastic blocks 52, so that the best conveying effect is maintained, and a micro motor is fixedly arranged at one end of the rotating roller 5 and used for driving the rotating roller 5 to rotate and guide the material strip 2 to advance.
[0044] In order to optimize the negative pressure air suction effect and enhance the air flow guiding property, longitudinal flow guides 7 are symmetrically arranged on the inner wall of the drying box 1, the longitudinal flow guides 7 are arc-shaped, and the longitudinal flow guides 7 are located directly above the air suction ports 11, so that the air flow above is guided to flow more smoothly to the air suction ports 11, the hot and humid air in the drying box 1 is effectively guided to the air suction ports 11, and the smoothness and efficiency of the air flow are improved.
[0045] C-shaped transverse flow guides 8 are symmetrically arranged on the both sides of each air suction port 11, the C-shaped transverse flow guides 8 are arranged with the C-shaped openings facing the opposite sides of the air suction ports 11, so that the negative pressure air suction effect is optimized, the air flow guiding property is enhanced, and powerful support is provided for the drying treatment of the material strip 2.
[0046] In specific use, the wiping plate 6 is inserted into the slot 13 and then deeply inserted into the drying box 1, then the material strip 2 to be dried is inserted into the input end of the drying box 1 after passing through the water of the discharging machine, the material strip 2 passes through the through hole 61 of the wiping plate 6 and then passes through the cross groove 921 and pushes the elastic plate 92 to the periphery, the dense bristles arranged on the inner wall of the wiping plate 6 can contact and wipe off most of the water on the surface of the material strip, then one end of the wiping plate 6 is arranged in the ring groove 51 of the rotating roller 5, and the material strip 2 is stably conveyed to the output end of the drying box 1 along the path of the ring groove 51 as the rotating roller 5 rotates, in the process, the air suction equipment is started, the air suction pipe 4 starts to work, the material strip 2 is negatively suctioned and dried through the air suction port 11, and the water on the material strip 2 is absorbed into the air suction box 3, in the negative pressure air suction process, the longitudinal flow guides 7 and the transverse flow guides 8 jointly guide the air flow to ensure that the air flow flows smoothly to the air suction port 11.
