Description

Technical Field

[0001] This utility model relates to the field of cow leather processing technology, specifically to an environmentally friendly cow Nappa leather processing equipment that can precisely control the tumbled texture effect. Background Technology

[0002] Cow leather is made from raw cowhide through chemical and physical processing, transforming it into a product that is not easily perishable and has properties such as flexibility and breathability. The production of finished leather requires dozens of processes: raw hide, soaking, fleshing, degreasing, hair removal, alkali soaking, swelling, deliming, softening, acid soaking, tanning, splitting, leveling, retanning, neutralization, dyeing, oiling, filling, drying, finishing, coating, and finished leather.

[0003] The tumbled texture effect requires spray coating control, mainly because the spray coating process directly affects the thickness, uniformity, and physical properties of the coating on the leather surface, which in turn determines the clarity, three-dimensionality, and durability of the tumbled texture.

[0004] However, traditional spraying operations are mostly done manually. Manual spraying is prone to uneven coating thickness, resulting in different depths of texture on the same leather surface, or even local cracking, affecting the tumbled texture effect. In addition, the surface may be contaminated with some dust and impurities. If they are not cleaned, the smoothness of the leather surface after spraying may be affected, which will affect the integrity of the leather coating. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an environmentally friendly cowhide Nappa leather processing equipment that can precisely control the tumbled texture effect, including a frame, a conveyor belt inside the frame, an electric push rod on the upper side of the frame, and the output end of the electric push rod passing through the frame and connected to a lifting seat;

[0006] An air pump is installed on one side of the lifting seat, and a filter box is installed on the other side of the upper side of the lifting seat. A groove is opened on the lower side of the lifting seat, and a spraying part is installed inside the groove. A storage cavity is provided on both sides of the lower side of the lifting seat. A cleaning roller and an electric heating layer are respectively installed inside the storage cavity. A storage box is installed on the upper side of the frame. A conveying pump is installed on one side of the storage box, and a three-way pipe is connected to one side of the conveying pump.

[0007] In the above scheme: the spraying unit includes a bidirectional lead screw, a driving component is provided on one side of the bidirectional lead screw, spraying boxes are slidably connected to both sides of the bidirectional lead screw, and nozzles are provided on the lower side of the spraying box.

[0008] In the above scheme: a telescopic rod is provided on the upper side of the frame, and the lower side of the telescopic rod is connected to the lifting seat.

[0009] In the above scheme: the lifting seat is provided with a rectangular through hole, and the lower side of the three-way pipe passes through the rectangular through hole and is connected to the upper side of the spray box.

[0010] In the above scheme: a controller is provided on one side of the rack.

[0011] This invention provides an environmentally friendly processing device for cowhide Nappa leather that can precisely control the tumbled texture effect, and has the following beneficial effects:

[0012] 1. The electric push rod drives the lifting seat to move precisely, allowing the spraying unit to accurately adjust the distance between itself and the cowhide Nappa leather. The bidirectional screw in the spraying unit works with the drive components to drive the spraying boxes on both sides to move flexibly. It can accurately control the spraying range and spraying amount according to the characteristics of different parts of the leather, ensuring uniform coating thickness. This achieves precise control of the spraying, making the leather surface have clear texture, strong three-dimensionality and good durability, greatly improving the quality of cowhide Nappa leather and meeting the market demand for high-quality leather.

[0013] 2. By installing cleaning rollers and electric heating layers in the storage cavities on both sides of the lifting seat, the cleaning rollers can effectively clean the dust and impurities on the leather surface before spraying, avoiding any impact on the spraying effect and the integrity of the leather coating. After spraying, the electric heating layer can quickly dry the leather, improving production efficiency. All of the above operations are completed by a single air pump, ensuring coordinated overall operation. Attached Figure Description

[0020] Example

[0021] Please see Figures 1-4 An environmentally friendly processing equipment for cowhide Nappa leather that can precisely control the tumbled texture effect includes a frame 1, a conveyor belt 2 inside the frame 1, an electric push rod 3 on the upper side of the frame 1, and an output end of the electric push rod 3 passing through the frame 1 and connected to a lifting seat 4.

[0022] An air pump 5 is installed on the toilet side of the lifting seat 4, and a filter box 6 is installed on the other side of the upper side of the lifting seat 4. A groove is opened on the lower side of the lifting seat 4, and a spraying part is installed inside the groove. A storage cavity is provided on both sides of the lower side of the lifting seat 4. A cleaning roller 7 and an electric heating layer 8 are respectively installed inside the storage cavity. A storage box 9 is installed on the upper side of the frame 1. A conveying pump 10 is installed on one side of the storage box 9, and a three-way pipe 11 is connected to one side of the conveying pump 10.

[0023] The spraying unit includes a bidirectional lead screw 12, a drive component 13 is provided on one side of the bidirectional lead screw 12, and spraying boxes 14 are slidably connected to both sides of the bidirectional lead screw 12. A nozzle is provided on the lower side of the spraying box 14.

[0024] It should be noted that when performing tumbled finishing on cowhide Nappa leather, spraying control is required, mainly because the spraying process directly affects the thickness, uniformity, and physical properties of the coating on the leather surface, which in turn determines the clarity, three-dimensionality, and durability of the tumbled finish.

[0025] At this time, the cowhide Nappa leather can be transported through the transmission belt. Then, the electric push rod 3 can be controlled to run and drive the lifting seat 4 to approach the leather. At this time, the bidirectional screw 12 and the drive component 13 cooperate to drive the two spray boxes 14 on both sides to move flexibly. According to the characteristics of different parts of the leather, the spraying range and spraying amount can be precisely controlled to ensure uniform coating thickness. The precise control of spraying is achieved, making the leather surface texture clear, three-dimensional and durable, which greatly improves the quality of cowhide Nappa leather and meets the market demand for high-quality leather.

[0026] The cleaning roller 7 is equipped with a drive device on one side, which can drive the cleaning roller 7 to rotate, so that the leather surface before the spraying operation can be sprayed. At the same time, the air pump 5 runs to extract the dust generated during the cleaning process and collect the dust through the filter box 6. The air outlet of the air pump 5 can blow out high-speed gas, which is blown out through the other side of the lifting seat 4. With the help of the motor heating layer, hot air can be blown out, which can then dry the sprayed leather, improving production efficiency. All of the above operations are completed by one air pump 5, and the overall operation is coordinated.

[0027] A telescopic rod 15 is provided on the upper side of the frame 1. The lower side of the telescopic rod 15 is connected to the lifting seat 4 to increase the integrity of the lifting seat 4. A rectangular through hole is provided on the lifting seat 4. The lower side of the T-pipe 11 passes through the rectangular through hole and is connected to the upper side of the spray box 14. The storage box 9 is filled with spraying material. The conveying pump 10, together with the T-pipe 11, can send the material into the movable spray box 14. The lower side of the T-pipe 11 is a flexible hose to keep it connected at all times. A controller 16 is provided on one side of the frame 1 for easy control of the device.
