Description

Technical Field

[0001] This utility model belongs to the field of leather production technology, specifically a high-efficiency drying device for leather processing. Background Technology

[0002] Leather includes natural animal leather and artificial leather. Artificial leather is made by foaming or coating various formulations of PVC and PU on a base fabric. In the production of artificial leather, in order to quickly dry the basic leather mixture, a high-efficiency drying device for leather processing is proposed.

[0003] Among them, a search revealed an application with application number CN202021736664.1, which discloses a drying device for leather processing, including a drying chamber. The drying chamber has a first limiting groove and a second limiting groove on both sides. An installation plate is installed inside the drying chamber. The device utilizes a rotary motor, elliptical blocks, a sliding rod, a second limiting groove, a second limiting plate, and a drain hole. When the rotary motor operates, two sets of rotating shafts drive multiple sets of elliptical blocks to rotate under the action of a belt and pulley. This causes the support plate to vibrate up and down on the sliding rod, thereby shaking off water from the leather, reducing drying time and improving drying efficiency. A screw, first limiting groove, first limiting plate, ball bearings, a first ball bearing groove, and a second ball bearing groove are also included. Rotating the screw causes the rotating block to rotate within the rotating groove, which in turn drives the installation plate to move vertically. This allows adjustment of the distance between the electric heating fan and the leather, enabling better drying of the leather. Furthermore, the ball bearings, the first ball bearing groove, and the second ball bearing groove make rotation less labor-intensive.

[0004] However, research has revealed that the device lacks a structure for continuous conveying of the base fabric and leather, making feeding difficult and unsuitable for producing longer pieces of leather, thus limiting its use. The device performs a single drying operation on the leather, resulting in insufficient drying and poor drying effect. Furthermore, the device lacks a structure for rolling up the dried leather, requiring manual winding, which is inconvenient and inefficient. Therefore, a new type of device is proposed to solve these problems. Utility Model Content

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the conveying mechanism, through two implementation methods, facilitates the change of the position of the limiting plate, so that the conveying roller contacts the base fabric. Motor A drives the feeding roller to rotate, and the starting end of the clamped base fabric moves slowly, reducing the difficulty of feeding. Moreover, the conveying roller, conveying shaft and guide roller cooperate with each other to periodically and continuously convey the base fabric and leather, resulting in higher work efficiency.

[0013] 2. In this utility model, the base fabric soaked in the leather mixture solution is placed in a drying chamber formed by overlapping air hoods A and B through a drying mechanism. The hot air generated by the hot air blows out from the air outlets on the inner walls of air hoods A and B to the surface of the base fabric, drying the leather mixture solution on the surface of the base fabric to form leather. During this process, the servo motor B works, driving the air guide rod to rotate. The impeller outside the air guide rod disperses the hot air, making the hot air flow faster and the flow area wider, resulting in a better drying effect for the leather. The motor C drives the guide roller and the conveyor shaft to rotate, clamping the dried leather and moving it in the drying tank for secondary drying, making the drying more thorough and the drying effect better.

[0014] 3. In this utility model, the worker assists by wrapping the starting end of the leather around the outside of the take-up roller. Then, the motor B drives the connecting plate A, the take-up roller and the connecting plate B to rotate, wrapping the dried leather around the outside of the take-up roller to complete the leather winding work. The take-up roller is easy to replace and more convenient to use. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In this utility model:

[0027] Reference Figure 1-9 A high-efficiency drying device for leather processing includes a support frame 1, a cloth roll rack installed on one side above the support frame 1, a conveying trough 101 fixedly installed above the support frame 1 near the cloth roll rack, and a cross frame 103 fixedly installed above the support frame 1.

[0028] The conveying trough 101 is equipped with a conveying mechanism that can continuously convey the leather roll, and the support frame 1 is equipped with a drying mechanism that can quickly dry the leather.

[0029] Example 1:

[0030] Reference Figure 1 , 34, 8. In this embodiment, the conveying mechanism includes a limiting plate 1011, a servo cylinder 1012, a feeding roller 102, and a motor A1021. The limiting plate 1011 is installed at the top of the conveying trough 101 via the servo cylinder 1012. Feeding rollers 102 are rotatably connected and embedded below the limiting plate 1011 and at the lower edge of the conveying trough 101. The number of feeding rollers 102 is at least ten pairs, and adjacent feeding rollers 102 are connected by chain drive. A sprocket that meshes with the chain is nested outside the feeding roller 102. A motor A1021 is installed at the lower edge of the conveying trough 101 and on one side of the limiting plate 1011. The output shaft of the motor A1021 is connected to the corresponding feeding roller 102 via a coupling.

[0031] The worker inserts the starting end of the base fabric roll on the fabric roll rack into the inside of the conveying groove 101. The servo cylinder 1012 extends, driving the limiting plate 1011 to move down, so that the feeding roller 102 below the limiting plate 1011 clamps the upper surface of the base fabric. The motor A1021 works, driving the feeding roller 102 to rotate, and slowly moving the clamping starting end of the base fabric, so that the base fabric roll is slowly unwound until the starting end of the base fabric passes out from the outlet on one side of the conveying groove 101.

[0032] Reference Figure 1 , 3 6. In this embodiment, a liquid tank 104 is embedded in the middle of the support frame 1 corresponding to the cross frame 103. A lead screw 2 is symmetrically rotated between the support frame 1 and the cross frame 103 via a servo motor A201. A guide rod 204 is symmetrically fixedly installed between the support frame 1 and the cross frame 103 near the lead screw 2. A slider 202 is nested and threadedly connected to the outside of the lead screw 2. The guide rod 204 passes through the corresponding slider 202 through a through hole. A connecting frame 2021 is fixedly installed on one side of the two sliders 202. A guide groove 203 is fixedly installed below the connecting frame 2021. A guide roller 2031 is rotatably connected inside the guide groove 203. Several punches are embedded in the bottom surface of the guide groove 203.

[0033] The worker pulls the starting end of the base fabric, which is exiting from one side of the conveying trough 101, to the guide trough 203 and assists in passing the starting end of the base fabric through the guide trough 203. The servo motor A201 drives the lead screw 2 to rotate, which in turn drives the slider 202 to slowly move down along the guide rod 204, so that the guide trough 203 slowly moves down and is immersed in the leather mixing solution inside the liquid tank 104. During this process, the motor A1021 drives the feeding roller 102 to rotate and continue to convey the base fabric. The worker manually fixes the starting end of the base fabric so that the starting end of the base fabric is always above the liquid tank 104 and does not come into contact with the leather mixing solution. The base fabric inside the liquid tank 104 is in full contact with the leather mixing solution.

[0034] Reference Figure 1 , 2In this embodiment, the drying mechanism includes a hot air blower 3, a fan hood A301, an exhaust fan 3011, a fan hood B302, an air guide rod 303, and a servo motor B3031. The hot air blower 3 is fixedly installed above the support frame 1. The fan hood B302 is fixedly installed on one side below the cross frame 103. The fan hood A301 is slidably connected to the bottom of the cross frame 103 via a slide rail. Magnets A and B, which attract each other, are embedded along one edge of the fan hood A301 and one edge of the fan hood B302, respectively. Several air outlets are embedded in the inner walls of both the fan hood A301 and the fan hood B302. The exhaust fan 3011 is installed on one side of the bottom of the fan hood A301 via a through slot. The fan hoods A301 and B302 rotate inside each other. A guide rod 303 is dynamically connected, and several impellers are equidistantly nested on the outside of the guide rod 303. There are at least five guide rods 303 inside the hoods A301 and B302, and adjacent guide rods 303 are connected by chain drive. A servo motor B3031 is installed at the bottom of the hoods A301 and B302, and the output shaft of the servo motor B3031 is connected to the corresponding guide rod 303 through a coupling. The hoods A301 and B302 are connected to the hot air blower 3 pipe. A drying trough 304 is fixedly installed above the cross frame 103, and the inlet of the drying trough 304 corresponds to the gap between the hoods A301 and B302. Guide rollers 3042 are symmetrically rotated at the inlet of the drying trough 304.

[0035] With the assistance of staff, the starting end of the base fabric is passed between two guide rollers 3042. The two guide rollers 3042 clamp and fix the starting end of the base fabric. Then, the air hood A301 is pushed so that it coincides with the air hood B302. Under the action of magnet A and magnet B, the air hoods A301 and B302 are lowered and magnetically fixed together, forming a semi-enclosed drying box. Then, the hot air blower 3 works, blowing the generated hot air from the air outlets on the inner walls of the air hoods A301 and B302 onto the surface of the base fabric, drying the base fabric surface. The leather mixture solution is dried to form leather. During this process, the servo motor B3031 works, driving the air guide rod 303 to rotate. The impeller outside the air guide rod 303 disperses the hot air, making the hot air flow faster and the flow area wider, resulting in a better drying effect for the leather. The exhaust fan 3011 works in conjunction to exhaust the water vapor generated during the drying process from inside the drying chamber. The leather stays inside the drying chamber, which is formed by the overlapping of the air hood A301 and the air hood B302, for 5 minutes, so that the leather is in a dry state.

[0036] Reference Figure 1 , 35. In this embodiment, conveyor shafts 3041 are equidistantly rotatably connected to both sides of the drying trough 304. The conveyor shafts 3041 are hollow inside and have several punched holes on their surface. Adjacent conveyor shafts 3041 and adjacent conveyor shafts 3041 and guide rollers 3042 are connected by chain drive. Sprockets that mesh with the chain are nested on the outside of the conveyor shafts 3041 and the outside of the guide rollers 3042. Motors C3043 are symmetrically installed on one side of the outside of the drying trough 304. The output shaft of motor C3043 is connected to the corresponding conveyor shaft 3041 through a coupling. The drying trough 304 is U-shaped and has several air outlets on its inner wall. The drying trough 304 is connected to the hot air blower 3 by a pipe.

[0037] Then, motors C3043 and A1021 work simultaneously, driving guide rollers 3042, conveyor shaft 3041, and feeding roller 102 to rotate at the same time, clamping the base fabric and continuing to move until the conveyor shaft 3041 rotates ten times, and the lower edge of the dried leather is exactly between the two guide rollers 3042. Then, the above work continues to dry the leather inside the drying box formed by the overlapping of the air hoods A301 and B302. During this process, the air blown out by the hot air blower 3 blows from the air outlet on the inner wall of the drying tank 304 to the surface of the dried leather, and performs secondary drying on the leather, making the drying effect of the leather better. This process is repeated to dry the leather section by section until all the base fabrics are soaked in the leather mixture solution and dried to form leather.

[0038] Reference Figure 1 , 3 7. In this embodiment, a take-up frame A105 is fixedly installed on the other side above the support frame 1. A connecting plate A1052 is installed on one side of the take-up frame A105 via a motor B1051. A take-up frame B106 is slidably connected to the support frame 1 at the corresponding position of the take-up frame A105 via a slide rail. An electric cylinder 1061 is installed on the support frame 1, and the end of the electric cylinder 1061 is connected to the take-up frame B106. A connecting plate B1062 is rotatably connected to one side of the take-up frame B106. A take-up roller 107 is movably connected between the connecting plate B1062 and the connecting plate A1052. Protrusions are symmetrically arranged on both sides of the take-up roller 107. A groove that fits the protrusion is embedded on one side of both the connecting plate B1062 and the connecting plate A1052.

[0039] The rotating conveyor shaft 3041 clamps the dried leather and moves it out of the drying tank 304. With the help of the staff, the starting end of the leather is wrapped around the outside of the take-up roller 107. Then, the motor B1051 drives the connecting plate A1052, the take-up roller 107 and the connecting plate B1062 to rotate, wrapping the dried leather around the outside of the take-up roller 107 to complete the leather winding. Then, the electric cylinder 1061 retracts, driving the take-up frame B106 away from the take-up roller 107. Then, a new take-up roller 107 is replaced to wind up the next section of leather, and so on.

[0040] Example 2:

[0041] In this utility model, the limiting plate 1011 can be installed inside the conveying groove 101 via the servo electric cylinder 1012, and there is another embodiment.

[0042] Reference Figure 9 In this embodiment, screws 1013 are symmetrically embedded in the top of the conveying groove 101 and are threadedly connected. The lower end of the screws 1013 extends into the conveying groove 101 and is rotatably connected to the limiting plate 1011.

[0043] The workers simultaneously turned the two screws 1013, causing the limit plate 1011 to move downward.

[0044] Reference Figure 1 , 3 In this embodiment, the servo electric cylinder 1012, motor A1021, motor B1051, electric cylinder 1061, servo motor A201, hot air blower 3, exhaust fan 3011, servo motor B3031 and motor C3043 are all electrically connected to an external power supply through a control panel.

[0045] Working principle: First, the operator inserts the starting end of the base fabric roll on the fabric roll holder through the inside of the conveying groove 101. The servo cylinder 1012 extends, driving the limiting plate 1011 to move downward. Alternatively, the operator simultaneously turns two screws 1013, causing the limiting plate 1011 to move downward, so that the feeding roller 102 below the limiting plate 1011 clamps the upper surface of the base fabric. Then, the motor A1021 operates, driving the feeding roller 102 to rotate, slowly moving the clamped starting end of the base fabric, causing the base fabric roll to slowly unwind until the starting end of the base fabric exits from one side of the conveying groove 101. Afterward, the operator assists in pulling the starting end of the base fabric to the guide groove 203 and assists in passing the starting end of the base fabric through the inside of the guide groove 203. The servo motor A201... The screw 2 is driven to rotate, which in turn drives the slider 202 to slowly move down along the guide rod 204, causing the guide groove 203 to slowly move down and immerse itself in the leather mixing solution inside the liquid tank 104. During this process, the motor A1021 drives the feeding roller 102 to rotate, continuing to convey the base fabric. The operator manually fixes the starting end of the base fabric, ensuring that the starting end of the base fabric is always above the liquid tank 104 and does not come into contact with the leather mixing solution. The base fabric inside the liquid tank 104 is in full contact with the leather mixing solution. Then, the operator assists in passing the starting end of the base fabric through the two guide rollers 3042. The two guide rollers 3042 clamp and fix the starting end of the base fabric. Then, the fan hood A301 is pushed so that it coincides with the fan hood B302, and the magnet blocks A and B are aligned. The air hoods A301 and B302 are magnetically fixed together to form a semi-enclosed drying chamber. Then, the hot air blower 3 operates, blowing hot air from the air outlets on the inner walls of air hoods A301 and B302 onto the surface of the base fabric, drying the leather mixture solution on the base fabric surface to form leather. During this process, the servo motor B3031 operates, driving the guide rod 303 to rotate. The impeller outside the guide rod 303 disperses the passing hot air, making the hot air flow faster and wider, resulting in better drying of the leather. The exhaust fan 3011 assists in removing the water vapor generated during the drying process from inside the drying chamber. The leather remains inside the drying chamber formed by the overlapping air hoods A301 and B302 for 5 minutes, allowing the leather to dry completely. In the drying state, motors C3043 and A1021 work simultaneously, driving guide rollers 3042, conveyor shaft 3041, and feeding rollers 102 to rotate simultaneously, clamping the base fabric and continuing to move until the conveyor shaft 3041 rotates ten times, at which point the lower edge of the dried leather is exactly between the two guide rollers 3042. This process continues, drying the leather inside the drying chamber formed by the overlapping of air hoods A301 and B302. During this process, air blown from the hot air blower 3 from the air outlet on the inner wall of the drying tank 304 onto the surface of the dried leather, performing secondary drying for better results. This process is repeated, drying the leather section by section, until all the base fabric has been impregnated with the leather mixture solution and dried to form leather.Finally, the rotating conveyor shaft 3041 clamps the dried leather and removes it from the outlet of the drying tank 304. With the help of staff, the starting end of the leather is wrapped around the outside of the take-up roller 107. Then, motor B1051 drives connecting plate A1052, take-up roller 107, and connecting plate B1062 to rotate, wrapping the dried leather around the take-up roller 107 to complete the winding process. Afterwards, electric cylinder 1061 retracts, moving the take-up frame B106 away from the take-up roller 107. Then, a new take-up roller 107 is replaced to wind up the next section of leather, and this process is repeated.
