Description

Printing device for microfiber printed sheepskin Technical Field

[0001] This utility model relates to a printing device, specifically a printing device for microfiber printed sheepskin, belonging to the field of microfiber printed sheepskin processing technology. Background Technology

[0002] Lambskin is a type of leather with a suede-like feel, while its microfiber substrate gives it better abrasion resistance, breathability, and environmental friendliness. When printing on lambskin using a UV leather printer, special process adjustments are required due to its suede structure and porous nature to ensure clear patterns, vibrant colors, and strong adhesion.

[0003] However, when printing on lambskin with existing UV leather printers, operators typically use masking tape to fix the edges of the lambskin to the machine. This is not very convenient, and the uneven tension of the tape can easily cause the edges of the lambskin to stretch and deform, which may affect the processing effect of the lambskin. Summary of the Invention

[0004] The purpose of this invention is to provide a printing device for microfiber printed sheepskin to solve the above problems. The bracket slides and drives the pressure roller to move on the sheepskin, which can flatten the sheepskin. When the hydraulic rod is activated, the pressure plate drives the rubber pad to abut against the edge of the sheepskin, thereby fixing the sheepskin when the inkjet print head prints on the sheepskin, thus making the printing effect better.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a microfiber printing device for sheepskin leather, comprising a body, an inkjet print head slidably mounted on the body, two drive mechanisms symmetrically fixed on the body, a bracket fixed on the drive mechanism, a limiting mechanism mounted on the bracket, the limiting mechanism comprising a support rod and a hydraulic rod, two support rods fixedly connected to the bracket, a hydraulic rod fixedly mounted at the top of the support rod, a pressure plate fixedly connected to the telescopic end of the hydraulic rod, a rubber pad engaged on the pressure plate, a long rod fixedly connected to the bracket, and a pressure roller rotatably connected to the long rod.

[0006] Preferably, the two support rods are symmetrically installed at the top of the bracket, and the support rods are arranged in an L-shape, while the bracket is arranged in an inclined plane.

[0007] Preferably, the limiting mechanism further includes a slot, and the bottom end of the pressure plate is provided with a slot, and a rubber pad is engaged and installed in the slot.

[0008] Preferably, the side of the pressure plate away from the pressure roller is arranged with an inclined structure, and the part where the rubber pad engages with the pressure plate is also arranged with an inclined structure.

[0009] Preferably, a conveyor belt is rotatably mounted on the machine body, and the inkjet printhead is located at the top of the conveyor belt.

[0010] Preferably, the long rod passes through the inner wall of the bracket and the pressure roller, and the pressure roller is rotatably connected to the bracket.

[0011] Preferably, the drive mechanism includes a fixed frame and a support plate. Two fixed frames are symmetrically fixedly connected to the body, and a support plate is fixedly connected to the fixed frame. An electric push rod is fixedly installed on the support plate.

[0012] Preferably, the support plate is located on the side wall of the fixed frame away from the machine body, and the support plate is arranged in an L-shape.

[0013] Preferably, the end of the electric push rod is fixedly connected to the bracket, and the telescopic end of the electric push rod is slidably connected to the fixed frame.

[0014] The beneficial effects of this invention are as follows: When the sheepskin is placed on the machine body, during the printing process, the support moves the pressure roller installed on the long rod, which can make the pressure roller contact the surface of the sheepskin. The pressure roller rolls on the surface of the sheepskin, which can flatten the sheepskin. The flattened fibers are tightly attached to the base, making the inkjet pattern clearer and avoiding smudging or rough edges. The hydraulic rod installed on the support rod is activated. The telescopic end of the hydraulic rod can drive the pressure plate fixed to it to move down. A rubber pad is installed inside the pressure plate. When the rubber pad contacts the surface of the sheepskin, it can fix the edge of the sheepskin when the inkjet print head moves. This helps to prevent the unfixed sheepskin from wrinkling due to uneven tension during printing, which may lead to ink accumulation or missing prints. Attached Figure Description

[0022] 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.

[0023] Please refer to Figures 1-6. The microfiber printing device for sheepskin includes a body 1, on which an inkjet printhead 2 is slidably mounted. Two drive mechanisms 4 are symmetrically fixed on the body 1, and a bracket 5 is fixed on each drive mechanism 4. The bracket 5 has an inclined structure and a limiting mechanism 6 is installed on the bracket 5. The limiting mechanism 6 includes a support rod 601 and a hydraulic rod 602. Two support rods 601 are fixedly connected to the bracket 5. The support rods 601 have an L-shaped structure, and a hydraulic rod 602 is fixedly installed at the top of each support rod 601. A pressure plate 603 is fixedly connected to the telescopic end of the hydraulic rod 602. The bottom end of the pressure plate 603 has a slot 607, on which a rubber pad 604 is engaged. The telescopic end of the hydraulic rod 602 drives the pressure plate 603 to move downward. When the rubber pad 604 contacts the surface of the sheepskin, the pressure plate 603 can fix the edge of the sheepskin when the inkjet printhead 2 moves. The fixed design helps prevent uneven tension from causing wrinkles in the unfixed sheepskin during printing, which could lead to ink buildup or printing defects. The part where the rubber pad 604 engages with the pressure plate 603 is designed with an angled structure, allowing for easy replacement of the rubber pad 604 after prolonged use. A long rod 606 is fixedly connected to the bracket 5, and a pressure roller 605 is rotatably connected to the long rod 606. The bracket 5 drives the pressure roller 605 to move, thus pressing... The roller 605 contacts the surface of the sheepskin leather, and the two rollers 605 roll towards each other on the surface of the sheepskin leather. When the rollers 605 move towards the fixed frame 401, they can flatten the sheepskin leather. The flattened fibers are tightly attached to the base, making the inkjet pattern clearer and avoiding smudging or rough edges. The long rod 606 passes through the inner wall of the bracket 5 and the rollers 605, and the rollers 605 are rotatably connected to the bracket 5. The pressure plate 603 is set with an inclined structure on the side away from the rollers 605.

[0024] As a technical optimization of this utility model, a conveyor belt 3 is rotatably mounted on the machine body 1, and the inkjet print head 2 is located at the top of the conveyor belt 3. The sheepskin is placed on the surface of the conveyor belt 3. When the conveyor belt 3 rotates, it can transport the sheepskin to a position close to the inkjet print head 2.

[0025] As a technical optimization of this utility model, the driving mechanism 4 includes a fixed frame 401 and a support plate 402. Two fixed frames 401 are symmetrically fixedly connected to the body 1. The support plate 402 is fixedly connected to the fixed frame 401. An electric push rod 403 is fixedly installed on the support plate 402. The end of the electric push rod 403 is fixedly connected to the bracket 5. When the electric push rod 403 is started, its telescopic end can drive the bracket 5 to move closer to the inkjet printhead 2. The telescopic end of the electric push rod 403 is slidably connected to the fixed frame 401. The support plate 402 is located on the side wall of the fixed frame 401 away from the body 1, and the support plate 402 is arranged in an L-shape.

[0026] In use, the sheepskin is first placed on the surface of the conveyor belt 3 mounted on the machine body 1. When the conveyor belt 3 rotates, it transports the sheepskin to a position close to the inkjet printhead 2. Fixtures 401 are mounted on both sides of the machine body 1, and support plates 402 are mounted on the fixtures 401. When the electric push rod 403 fixed on the support plate 402 is activated, its telescopic end moves the bracket 5 closer to the inkjet printhead 2. The bracket 5 then moves the pressure roller 605 mounted on the long rod 606, allowing the pressure roller 605 to contact the surface of the sheepskin. The two pressure rollers 605 roll towards each other on the surface of the sheepskin. As the pressure rollers 605 move towards the fixtures 401, they flatten the sheepskin. The flattened fibers adhere tightly to the substrate, making the inkjet pattern clearer. To avoid smudging or rough edges, after the sheepskin is flattened, the operator activates the hydraulic rod 602 installed on the support rod 601. The telescopic end of the hydraulic rod 602 can drive the pressure plate 603, which is fixed to it, to move down. A rubber pad 604 is installed inside the pressure plate 603. When the rubber pad 604 contacts the surface of the sheepskin, the pressure plate 603 can fix the edge of the sheepskin when the inkjet printhead 2 moves. This helps to prevent the unfixed sheepskin from wrinkling due to uneven tension during printing, which may lead to ink accumulation or missing prints. After the sheepskin is fixed, the surface of the sheepskin can be cleaned with a lint-free cloth and deionized water, which will help improve the adhesion of the ink. When the inkjet printhead 2 moves on the surface of the sheepskin, it can spray high-viscosity UV ink onto the surface of the sheepskin, which can then be printed.
