DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] See also Figure 1 , Figure 2 and Figure 3A cloth drying device comprises a water squeezing mechanism 1, a water absorbing mechanism 2, a drying mechanism 3, a driving mechanism 4 and a frame 6. The water squeezing mechanism 1, the water absorbing mechanism 2, the drying mechanism 3 and the driving mechanism 4 are all installed on the frame 6. The cloth first passes through the water squeezing mechanism 1 from bottom to top to squeeze and remove water, then passes through the water absorbing mechanism 2 from left to right to adsorb and remove water, and finally passes through the drying mechanism 3 from top to bottom to dry and remove water with hot air. The water in the cloth is quickly removed in advance by squeezing and adsorbing water, which significantly shortens the time required for subsequent drying, quickly and efficiently completes the drying process of the cloth, and improves the efficiency of cloth drying. In the drying process, the hot air of the drying mechanism 3 is reused for a second time to further improve the efficiency of the cloth drying process and the stability of the continuous drying process, thereby improving the utilization rate of energy.

[0025] See also Figure 1 , Figure 3 and Figure 4 The water squeezing mechanism 1 includes an extrusion belt 101, a check plate 103 and a plurality of rollers 102. The extrusion belt 101 is symmetrically arranged. The plurality of rollers 102 are divided into two groups. The two groups of rollers 102 are symmetrically distributed and correspond to the symmetrical extrusion belts 101 and limit the paths of the corresponding extrusion belts 101. The check plates 103 are symmetrically distributed and correspond to the extrusion belts 101 one by one and are located below the corresponding extrusion belts 101. The rollers 102 are rotatably connected to the frame 6, and the check plates 103 are fixedly connected to the frame 6. Figure 3 As shown, the cloth passes through the middle of the symmetrical check plates 103 and the symmetrical extrusion belts 101 from bottom to top in sequence, the left-right symmetrical extrusion belts 101 are in contact with the cloth and squeeze the cloth, and at the same time, the extrusion belts 101 move from top to bottom on one side close to the cloth, squeezing the cloth while fully pushing the squeezed water downward, the check plates 103 guide the pushed water, and effectively prevent the squeezed water from returning to the un-squeezed cloth again, which is beneficial to improving the stability of the extrusion dehydration work and the effect of continuous extrusion dehydration.

[0026] See also Figure 2 , Figure 3 and Figure 4The water absorption mechanism 2 includes a water absorption roller 21, a water removal roller 22 and a drying head 23. The water absorption roller 21, the water removal roller 22 and the drying head 23 are all located above the squeezing belt 101. The water absorption roller 21 is symmetrically distributed on the left and right and is rotatably mounted on the frame 6. The water removal roller 22 corresponds to the water absorption roller 21 one by one and is rotatably mounted on the frame 6. The drying head 23 is fixedly mounted on the frame 6 and corresponds to the water absorption roller 21 on the right. The cloth passes through the squeezing mechanism 1 from top to bottom and is squeezed and dehydrated, then enters the water absorption mechanism 2 and passes through the symmetrical water absorption rollers 21 from left to right in sequence. The water removal roller 22 corresponds to the water absorption roller 21 one by one and is squeezed and contacted, and the water absorption roller 21 and the water removal roller 22 have the same rotation direction. The drying head 23 corresponds to the water absorption roller 21 on the right and generates hot air after the water removal roller 22 removes water and acts on the water absorption roller 21. Figure 3 As shown in the figure, the rotation direction of the water-absorbing roller 21 is the same as the conveying direction of the cloth. When the cloth passes through the water-absorbing roller 21, the rotating water-absorbing roller 21 prolongs the contact time between the cloth and the water-absorbing roller 21, which is conducive to fully absorbing the water in the cloth and improving the dewatering effect. In the process of the water-absorbing roller 21 rotating to absorb water, the dewatering roller 22 always squeezes the water-absorbing roller 21 in the non-water-absorbing area to remove the water in the water-absorbing roller 21. After the dewatering roller 22 removes water from the water-absorbing roller 21, the drying head 23 further dries the water-absorbing roller 21 on the right side to further remove the water in the water-absorbing roller 21, so that the water-absorbing roller 21 always maintains a stable water-absorbing state. The water is absorbed by the fabric in a stable and sufficient manner, ensuring that the fabric that is about to enter the drying mechanism 3 is dehydrated stably and sufficiently, which is beneficial to improving the dehydration effect of the fabric and the stability and reliability of the continuous dehydration treatment. Among them, in order to further remove the moisture on the water-absorbing roller 21, a fixed roller 24 is fixedly installed on the frame 6, and the fixed roller 24 corresponds to the water-absorbing roller 21 one by one and squeezes the water-absorbing roller 21. When the water-absorbing roller 21 is dehydrated by the squeezing of the dehydrating roller 22 and then passes through the fixed roller 24, the squeezing of the fixed roller 24 is used to further perform dehydration treatment, which is beneficial to further improve the dehydration effect of the water-absorbing roller 21 without setting a driving source.

[0027] See also Figure 2 , Figure 3 and Figure 4 The drying mechanism 3 includes a second drying head 34, a guide head 35, and a drying chamber 31 with an inlet 32 ​​at the top and an outlet 33 at the bottom. The drying chamber 31 is installed on the frame 6. The second drying head 34 is symmetrically distributed and slidably installed in the drying chamber 31. The guide head 35 is installed on the drying chamber 31 and is located at the inlet 32 ​​at the top. The cloth passes through the symmetrical water-absorbing rollers 21 from left to right in sequence, and then passes through the drying chamber 31 from top to bottom. Figure 3As shown, the fabric enters from the inlet 32 above the drying chamber 31, then passes through the middle of the symmetric drying heads two 34 on the left and right, and finally exits from the outlet 33 below. When the fabric passes through the symmetric drying heads two 34, the drying heads two 34 generate hot air that slopes upward to dry the fabric. Then, the hot air flows through the guide of the guide head 35 to the drying head one 23 and acts as the heat source of the drying head one 23 on the water absorption roller 21. The drying head one 23 reuses the heat energy in the drying mechanism 3, which not only improves the utilization rate of heat energy, but also improves the stability and reliability of the continuous drying process and effect of the fabric through the utilization of heat energy.

[0028] Refer to Figure 3 and Figure 4 , the water absorption roller 21 includes a flexible outer water absorption layer 211, a rigid inner support cylinder 212, and a sealing layer 213. The inner support cylinder 212 is evenly provided with emission holes 214. The inner support cylinder 212 is rotatably installed on the frame 6. The outer water absorption layer 211 is sleeved on the inner support cylinder 212. The sealing layer 213 abuts against the inner wall of the inner support cylinder 212 and passes through the rear end of the inner support cylinder 212 to be fixedly installed on the frame 6, and corresponds to the water removal roller 22 at the same time. During the process of the water absorption roller 21 being dewatered by the corresponding water removal roller 22, the sealing layer 213 blocks the emission holes 214 in the corresponding area of the inner support cylinder 212 to prevent the water in the outer water absorption layer 211 from being squeezed into the inside of the inner support cylinder 212 and affecting the water removal effect of the outer water absorption layer 211. When the water absorption roller 21 passes through the drying head one 23, the emission holes 214 are in an open state. The hot air generated by the drying head one 23 passes through the outer water absorption layer 211 and the emission holes 214 into the inner support cylinder 212. On the one hand, it is beneficial for the hot air generated by the drying head one 23 to fully remove the water in the outer water absorption layer 211. On the other hand, a drying environment with a certain temperature is formed in the inner support cylinder 212, which is beneficial to removing the water in the outer water absorption layer 211 and improving the stability and reliability of its water absorption state.

[0029] Refer to Figure 1 , Figure 2 and Figure 3 , the driving mechanism 4 includes a first driven part 41, a second driven part 42, a third driven part 43, and a central driving part 44. The central driving part 44 controls the rotation of the roller body 102 through the first driven part 41 to continuously move and squeeze the symmetric pressing belts 101 for water removal, controls the reverse rotation of the water absorption roller 21 and the water removal roller 22 through the second driven part 42, and controls the synchronous reverse and forward and backward reciprocating movement of the symmetric drying heads two 34 through the third driven part 43. In this way, the number of driving sources is effectively reduced, and the squeezing mechanism 1, the water absorption mechanism 2, and the drying mechanism 3 are arranged in a C shape. The first driven part 41, the second driven part 42, and the third driven part 43 are directly connected to the central driving part 44, which is beneficial to the continuous, stable, and reliable operation of the entire drying system.

[0030] See also Figure 1 , Figure 2 and Figure 3 The central driving part 44 includes a driving shaft 443 coaxially provided with a connecting pulley 441 and a conversion gear 442, and the driving shaft 443 is rotatably mounted on the frame 6. The first driven part 41 includes three transmission belts 411 and a plurality of pulleys 412. The pulleys 412 correspond to the roller bodies 102 one by one and the pulleys 412 are coaxially fixedly connected to the corresponding roller bodies 102 through the connecting shaft 414. The other end of the roller body 102 is rotatably connected to the frame 6. Among them, a connecting gear 413 is coaxially provided on the pulley 412 located on the upper right side of the group of roller bodies 102 on the right side, and the connecting gear 413 is connected to the conversion gear 442. The belt pulley 412 located on the upper left of the left group of roller bodies 102 is connected to the connecting belt pulley 441 through one of the transmission belts 411, and the other two transmission belts 411 respectively connect the corresponding belt pulleys 412 in the two groups of roller bodies 102 together, and the connecting shaft 414 is rotatably connected to the frame 6. The driving shaft 443 rotates to drive the connecting gear 413 to rotate through the conversion gear 442, thereby driving the corresponding belt pulley 412 to rotate. The belt pulley 412 drives the remaining corresponding belt pulleys 412 to rotate through the corresponding transmission belt 411, so that the corresponding extrusion belt 101 continues to move.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The second driven part 42 includes a pulley 421 and four transmission belts 422. The pulley 421 is coaxially connected to the water-absorbing roller 21 and the water-removing roller 22 through a connecting shaft 423. The connecting shaft 423 is rotatably installed on the frame 6. Due to the different diameters of the water-absorbing roller 21 and the water-removing roller 22, the diameters of the corresponding connecting shafts 423 will be different. The pulley 421 on the right water-absorbing roller 21 is connected to the connecting pulley 441 through a transmission belt 422, and the pulley 421 on the left water-absorbing roller 21 is connected to the pulley 421 on the right water-absorbing roller 21 through a transmission belt 422. At the same time, the pulley 421 on the left water-removing roller 22 is connected to the transmission belt 422 on the left water-absorbing roller 21 through a transmission belt 422, and the pulley 421 on the right water-removing roller 22 is also connected to the belt on the right water-absorbing roller 21 through a transmission belt 422. The drive belt 422 is connected to the pulley 421, and the length and size of the drive belt 422 can be changed according to the size, distance and other factors of the corresponding pulley 421. When the pulley 421 is connected to more than one drive belt 422, the pulley 421 is a multi-groove pulley, and the driving shaft 443 rotates. The connecting pulley 441 drives the corresponding water-absorbing roller 21 on the right side to rotate through the cooperation of the corresponding drive belt 422 and the pulley 421. At the same time, the pulley 421 on the right water-absorbing roller 21 drives the water-absorbing roller 21 on the left side to rotate in the same direction through the corresponding drive belt 422, and also drives the dewatering roller 22 on the right side to rotate in the same direction. The water-absorbing roller 21 on the left side rotates through the pulley 421 and the corresponding drive belt 422 thereon to drive the dewatering roller 22 on the left side to rotate in the same direction. During the rotation of the water-absorbing roller 21, the dewatering roller 22 rotates and squeezes the water-absorbing roller 21 to remove the moisture on the water-absorbing roller 21.

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The third driven part 43 includes a pulley 3 431, a transmission belt 3 432 and a conversion assembly 433. The pulley 3 431 is connected to the connecting pulley 441 through the transmission belt 3 432 and drives the conversion assembly 433 to control the symmetrical drying head 2 34 to move back and forth synchronously. The conversion assembly 433 includes a conversion box 4335 rotatably provided with an input shaft 4334. The conversion box 4335 is installed on the drying chamber 31.

Two connecting heads 4333 are slidably provided in the track groove 4331. The connecting heads 4333 are slidably connected in the conversion box 4335 forward and backward, and the ends of the connecting heads pass through the conversion box 4335 and are fixedly connected to the corresponding drying head 2 34. The pulley three 431 is coaxially fixedly connected with the input shaft 4334. The rotation of the pulley three 431 drives the input shaft 4334 to rotate, and the rotating body 4332 rotates with the input shaft 4334. During the rotation, the track groove 4331 causes the connecting head 4333 to move back and forth as it rotates, thereby driving the drying head 2 34 to move back and forth, and the symmetrical drying head 2 34 moves synchronously in the opposite direction, wherein the drying head 2 34 includes a base 342 provided with a plurality of air outlets 341, and the plurality of air outlets 341 are evenly divided into a plurality of rows, and the air outlets 341 in the plurality of rows are distributed from top to bottom, and the air outlets 341 in adjacent rows above and below are staggered in sequence, and the base 342 is fixedly connected to the corresponding connecting head 4333 and moves back and forth, and during the reciprocating movement, the activity of the hot air is increased, thereby improving the drying speed and effect.

[0033] See also Figure 3 and Figure 4 The present invention also includes a water collecting mechanism 5, which includes a wiper head 51 corresponding to the water removal roller 22, a wiper head 52 corresponding to the extrusion belt 101, and a water collecting tank 53 corresponding to the wiper head 51. The water collecting tank 53 is fixedly installed on the frame 6 and is used to receive and collect the water scraped by the corresponding wiper head 51. The wiper head 52 is symmetrically distributed on the left and right and corresponds to the extrusion belt 101 one by one. It scrapes off the water attached to the surface of the extrusion belt 101 during its movement, so as to improve the stability and reliability of the extrusion belt 101 in continuously circulating and extruding the fabric to remove water. Figure 3As shown, the second wiper head 52 is installed on the frame 6 and is located obliquely below the lower end of the corresponding check plate 103. When the extrusion belt 101 contacts and extrudes the fabric to complete the dewatering work and passes through the second wiper head 52, the second wiper head 52 automatically scrapes off the moisture attached to the surface of the extrusion belt 101, and the first wiper head 51 scrapes off the moisture attached to the surface of the dewatering roller 22 during the rotation of the dewatering roller 22, thereby improving the stability and reliability of the dewatering treatment of the water-absorbing roller 21 by the continuous rotation of the dewatering roller 22, wherein the first wiper head 51 includes a connecting frame 512 provided with a plurality of scraping openings 511, and the connecting frame 512 is installed on the inner wall of the water collecting tank 53, and the scraping openings 511 are distributed along the circumference of the dewatering roller 22 and abut against the outer circumferential surface of the dewatering roller 22, as shown in FIG. Figure 4 As shown, there are three scraping openings 511, which can fully scrape off the water attached to the surface of the water removal roller 22 during the rotation of the water removal roller 22. The second scraper head 52 is rotatably mounted on the frame 6 via a rotating shaft, and a scroll spring is arranged between the second scraper head 52 and the rotating shaft.
