Compared with the prior art, this utility model has the advantages of convenient operation, reduced worker workload, and improved work efficiency. It can also be integrated with a leather brushing machine to form a leather production line, improving the overall leather processing efficiency.
[0004] The leather drying equipment in the aforementioned leather production line may cause uneven heating of the leather during use due to single-sided drying, making the leather prone to curling or deformation. It also lacks the function of smoothing the leather, and the leather wrinkles require subsequent processing, thereby reducing work efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a leather drying and shaping machine to solve the problem that existing leather drying equipment in leather production lines is not convenient for flattening leather.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a leather drying and shaping machine, including a housing;
[0007] The box body has openings on both sides, and a conveyor belt is installed inside the openings. A leveling structure is installed at the top of the box body. The leveling structure includes brackets fixed to both sides inside the box body. A first rotating shaft is installed on one side of the top of each bracket. A roller is fixed to the outside of the first rotating shaft. A first motor is fixed at the top of the box body. A threaded rod is installed at the output end of the first motor. A lifting plate is installed on the outside of the threaded rod inside the box body. A guide rod is fixed at the top of the inside of the box body. A connecting rod is fixed at the bottom edge of the lifting plate. A connecting block is fixed at the bottom of each connecting rod. A second rotating shaft is installed inside the connecting block. A leveling roller is fixed to the outside of the second rotating shaft.
[0008] The interior of the chamber is equipped with a drying structure.
[0009] Preferably, a transmission wheel is fixed to one end of the second rotating shaft on one side of the connecting block, a transmission belt is installed on the outer side of the transmission wheel, and a second motor is installed at the other end of the second rotating shaft on one side of the connecting block.
[0010] Preferably, the two ends of the first rotating shaft extend through one side of the top of the bracket to the interior of the bracket and are rotatably connected to the interior of the bracket. The rollers are symmetrically distributed inside the box, and the outer side of the rollers abuts against the bottom side of the conveyor belt.
[0011] With the above structure, the rollers provide support to the conveyor belt during use, which can prevent the leather from deforming during transportation. At the same time, in conjunction with the gentle rolling of the leveling rollers, it ensures that the leveling rollers effectively compact the surface texture and avoid indentations.
[0012] Preferably, the bottom end of the threaded rod extends through the top of the housing and into the interior of the housing, where a limiting plate is fixed. The threaded rod is threadedly connected to the lifting plate. The guide rods are symmetrically distributed at the top of the housing. The guide rods inside the lifting plate have guide holes on their outer sides. The lifting plate and the guide rods are slidably connected.
[0013] With the above structure, the limiting plate prevents the threaded rod from disengaging from the lifting plate during use, ensuring that the adjustment range is controllable, and the guide rod constrains the lifting plate to move only in the vertical direction.
[0014] Preferably, the two ends of the second rotating shaft extend through one side of the connecting block and into the interior of the connecting block, forming a rotatable connection with the interior of the connecting block. The leveling rollers are symmetrically distributed at the bottom of the lifting plate, and the leveling rollers correspond one-to-one with the rollers.
[0015] With the above structure, the leveling roller and the roller correspond one-to-one to form a clamping structure during use, thereby ensuring uniform pressure.
[0016] Preferably, the drying structure includes a hot air blower fixed to one side of the chamber, a three-way pipe installed at the output end of the hot air blower, a first drying chamber installed at the top inside the chamber, a second drying chamber installed at the bottom inside the chamber, a first hot air nozzle fixed at the bottom of the first drying chamber, a second hot air nozzle fixed at the top of the second drying chamber, mounting brackets fixed on both sides of the first and second drying chambers, and a temperature sensor installed on one side inside the chamber.
[0017] Preferably, both ends of the three-way pipe extend through one side of the box body into the interior of the box body and are fixedly connected to one side of the first drying box and the second drying box. The first hot air nozzles are evenly distributed at the bottom of the first drying box, and the second hot air nozzles are evenly distributed at the top of the second drying box.
[0018] With the above structure, the first and second hot air nozzles work simultaneously during use, so that the upper and lower surfaces of the leather are heated evenly, avoiding deformation or uneven drying caused by one-sided drying.
[0019] The advantages of the leather drying and shaping machine provided by this utility model are as follows:
[0020] With a leveling structure, the height of the leveling roller can be flexibly adjusted through the cooperation of the threaded rod and the lifting plate to adapt to leathers of different thicknesses and hardnesses, thereby enhancing the versatility of the equipment. The leveling roller and the roller cylinder roll the leather to eliminate wrinkles and deformation, ensuring that the dried leather is flat and smooth, and improving the product yield.
[0021] By incorporating a drying structure, the simultaneous operation of the first and second hot air nozzles ensures that the upper and lower surfaces of the leather are heated evenly, avoiding deformation or uneven drying caused by single-sided drying, thus significantly improving drying efficiency. Furthermore, the temperature inside the chamber is monitored in real time by a temperature sensor to ensure stable drying temperature. Attached Figure Description

The rollers 403 are symmetrically distributed inside the housing 1. The outer side of the rollers 403 abuts against the bottom side of the conveyor belt 3. The bottom end of the threaded rod 405 extends through the top of the housing 1 and into the interior of the housing 1, where a limit plate is fixed. The threaded rod 405 and the lifting plate 4 06 is threaded, and the guide rods 407 are symmetrically distributed at the top of the box 1. The guide rods 407 inside the lifting plate 406 are provided with guide holes on the outside of the guide rods 407. The lifting plate 406 and the guide rods 407 are slidably connected. The two ends of the second rotating shaft 410 pass through one side of the connecting block 409 and extend into the interior of the connecting block 409, forming a rotatable connection with the interior of the connecting block 409. The leveling rollers 411 are symmetrically distributed at the bottom of the lifting plate 406. The leveling rollers 411 correspond one-to-one with the rollers 403.
[0031] The conveyor belt 3 is passed through the openings 2 on both sides of the box 1, and its tension is adjusted to ensure that the leather can be transported smoothly. The drive device of the conveyor belt 3 is started to match its running speed with the speed of the leveling roller 411 to avoid stretching or piling of the leather during the leveling process.
