Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, and in particular to a spraying device for leather production. Background Technology

[0002] Leather production spraying equipment is the core equipment in the leather finishing process. It mainly applies coating materials such as color paste, brightener, hand feel agent, and fixative to the leather surface in a mist spraying manner to improve the appearance and color, enhance the hand feel, improve wear resistance, water resistance, and aging resistance, and form a protective coating.

[0003] Application CN202222275464.6 discloses a spraying device for leather production. By extending and retracting a telescopic rod on one side of a fixed frame, one end of the leather can be pressed and fixed between a lower pressure plate and a fixed base plate. Similarly, the other end of the leather can be fixed between another set of lower pressure plates and fixed base plates, thus unfolding and securing the leather. The input end of the spray head is then connected to a paint pipe, allowing spraying of the leather within the fixed frame by activating the spray head, thereby avoiding direct contact between workers and the paint. However, in this patent, the fixed frame and the spray head require separate motors for driving. This dual-drive structure not only increases the equipment manufacturing cost but also leads to a significant increase in energy consumption, failing to meet current energy-saving and environmentally friendly industrial production requirements and lacking practicality. Furthermore, during the spraying process, some of the atomized coating material is not absorbed by the leather surface, and the device lacks any coating material collection mechanism, resulting in unabsorbed coating material dripping directly into the equipment or onto the ground, causing serious waste of coating material. Utility Model Content

[0004] The purpose of this invention is to provide a spraying device for leather production, which can evenly spray the paint inside the material box onto both sides of the leather, thereby effectively improving the spraying effect on the leather. It can also collect and reuse excess paint, thereby effectively reducing waste. At the same time, multiple components are driven by a single power source, namely a motor, which has low energy consumption and strong practicality.

[0031] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0032] Working principle: During operation, the leather is placed on both sides below the pressure plate 15 on the inner surface of the fixing frame 11. Then, the rotating block 14 is rotated, causing the limiting block 13 to drive the pressure plate 15 to clamp and fix the outer surface of the leather under the limiting action of the limiting block 13. Then, the liquid pump 3 and motor 9 are started. Under the action of the liquid pump 3, the paint inside the material box 1 is absorbed by the liquid inlet pipe 4 and then sprayed onto the leather through the hose 5, hollow plate 6, and mist nozzle 7 in sequence, thus realizing the spraying operation. Then, under the action of the motor 9, the rotating shaft 10 is driven to rotate the leather fixed inside the fixing frame 11, so that both sides of the leather can be sprayed to improve work efficiency. In addition, the meshing action of the third conical tooth 22 and the second conical tooth 20 can synchronously drive the transmission shaft 19 to rotate, and then cooperate with the second conical tooth 20 and the first conical tooth 19 to rotate. The meshing action of the first conical tooth 17 and the second conical tooth 20 and the fourth conical tooth 25 can drive the reciprocating threaded rod 16 and the stirring shaft 23 to rotate synchronously. Under the action of the reciprocating threaded rod 16, the connecting block 8 will move back and forth along the inside of the limiting groove 26, so that the paint sprayed by the mist nozzle 7 can be evenly attached to various parts of the leather. At the same time, under the action of the stirring shaft 23, the stirring blade 24 will be driven to stir the paint inside the material box 1, thereby reducing the stratification phenomenon caused by the paint settling, thus effectively improving the spraying effect. The sprayed paint will fall back into the material box 1 for collection so as to be reused, thereby effectively reducing paint waste. At the same time, the drive of the fixed frame 11, the reciprocating threaded rod 16 and the stirring blade 24 only requires a single power source, the motor 9, which has low energy consumption and strong practicality.
