Description
Technical Field
[0001] This utility model belongs to the field of leather production and processing technology, and in particular relates to a novel constant temperature conveying device for leather production lines. Background Technology
[0002] The new type of constant temperature conveying device for leather production lines is a specialized conveying equipment for leather production. It integrates conveying and constant temperature control structures, including a frame, conveyor belt, heating unit, temperature detection components, etc. It can flexibly adjust the conveying direction and angle to achieve constant and uniform temperature control during material conveying. It can also monitor the temperature in real time, adapting to the temperature control conveying requirements of leather production. Constant temperature conveying in leather production can ensure stable material processing performance, avoid temperature fluctuations that cause leather to wrinkle during rolling and uneven drying, reduce heat loss and energy consumption, and keep leather processing parameters consistent, improving the stability of finished product quality and adapting to the continuous operation requirements of the production line.
[0003] However, existing constant temperature conveying devices mostly use a single fixed heating source during use, which makes it difficult to achieve dynamic adjustment of the area. The structure has limitations in heat radiation transfer. During the conveying process, the leather is heated unevenly between the edge and the center area, resulting in a significant temperature difference. This leads to defects such as surface color difference and residual creases, which reduces product quality. Utility Model Content
[0004] The purpose of this utility model is to provide a new type of constant temperature conveying device for leather production lines. By setting up a constant temperature section, it solves the problems of existing constant temperature conveying devices, which often use a single fixed heating source, making it difficult to achieve dynamic adjustment of the area, and have limited heat radiation transfer in the structure. During the conveying process, the leather is heated unevenly between the edge and the center area, resulting in a significant temperature difference, which in turn leads to defects such as surface color difference and residual creases, thus reducing product quality.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The movable block is provided with a transmission component for pulling the movable block.
[0011] Furthermore, the heating element includes several infrared heating rods fixedly connected to the bottom of the mounting plate to maintain the temperature of the constant temperature chamber. Several fixing rods pass through the mounting plate. The outer walls of the fixing rods are slidably connected to the mounting plate. The infrared heating rods are infrared quartz heating tubes. Their working principle is that the heating wire inside the tube generates heat after being energized. The quartz tube acts as a carrier to transfer heat and convert the heat energy into infrared radiation. The infrared radiation is absorbed by the heated object and converted into internal energy, achieving rapid and directional heating. Moreover, the heating process is flameless and has high thermal efficiency.
[0012] Furthermore, the movable component includes two hinge blocks fixedly connected to the top of the mounting plate, two connecting blocks are provided inside the constant temperature chamber, the outer wall of the bidirectional threaded rod passes through the two connecting blocks, and each of the two hinge blocks is provided with a hinge element; both connecting blocks are threadedly connected to the outer wall of the bidirectional threaded rod.
[0013] Furthermore, the connector includes two slide rods fixedly connected to the fixed frame to provide a moving direction for the two guide plates. The outer walls of the two slide rods respectively penetrate the two guide plates. Two connecting rods are fixedly connected to the fixed frame, and the outer walls of the two connecting rods both penetrate the moving block. The outer walls of the two slide rods are slidably connected to the two guide plates respectively, and the outer walls of the two connecting rods are slidably connected to the moving block.

[0016] This utility model has the following beneficial effects:
[0017] 1. By setting up a constant temperature section, the heating distance of the infrared heating rod is adjusted through the cooperation of the motor, bidirectional threaded rod, hinge block, connecting block and hinge plate. This avoids the heat source being fixed, resulting in uneven heating of the leather, forming obvious temperature differences, which in turn leads to defects such as surface color difference and residual creases, thus improving product quality.
[0018] 2. By setting up a guide section, the interaction between the electric telescopic rod, the moving block and the connecting plate drives the two guide plates to move relative to each other, thereby guiding the leather on the conveying assembly. This prevents the leather from shifting due to external forces during the conveying process, which would cause uneven heating of the leather and improve the stability of the device during use.

This allows for flexible adjustment of the distance between the infrared heating rod 213 and the leather, avoiding a fixed heat source and uneven heating of the leather, which can lead to significant temperature differences and defects such as surface color differences and crease residue, thus improving product quality.

When the infrared heating rod 213 moves, the electric telescopic rod 323 is started, and the electric telescopic rod 323 pushes the moving block 321 to move along the connecting rod 314. When the moving block 321 moves, the connecting plate 322 drives the two guide plates 312 to move in opposite directions along the sliding rod 313 to transport and guide the leather on the conveying assembly 113, thus completing the constant temperature conveying of the leather.
