Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box stapler flat wire, specifically a rust-proof coating mechanism for cardboard box stapler flat wire. Background Technology

[0002] In cardboard box production, metal flat wires are key components for connecting cardboard boxes. However, exposed flat wires are prone to rusting. In food boxes or medicine boxes, this can directly contaminate the packaged items, reduce the strength of the cardboard box, and affect its appearance. Therefore, it is necessary to coat them with anti-corrosion paint.

[0003] Traditional cardboard box flattening line processing equipment suffers from three major pain points: First, poor positioning accuracy: manual feeding is prone to deviation, leading to uneven coating and resulting in nailing defects during use. Second, process separation: flattening and conveying require separate operations, resulting in low efficiency. Third, lack of automation: reliance on manual intervention leads to poor continuity and high costs. More specifically, existing technologies generally lack precision devices specifically designed for uniform, thin-layer coating of special workpieces like cardboard box staplers—which are 'long, continuous, and travel at high speeds'. Traditional methods often result in uneven coating thickness, surface drips or bubbles, or an excessively thick coating affecting subsequent staplering formation, while an excessively thin coating fails to meet rust prevention standards. These problems directly impact the product quality and production efficiency of cardboard box staplers. To address these issues, we propose a rust-proof coating mechanism for cardboard box staplers, specifically designed to solve the rust prevention problem of cardboard box staplers. Summary of the Invention

[0004] The purpose of this invention is to provide a special anti-rust coating mechanism for the flat stitching of cardboard boxes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special anti-rust coating mechanism for flat stitching of cardboard boxes, comprising a processing device, the processing device comprising a base, a support plate and a nozzle, the support plate being provided directly above the base, the nozzle being installed at the middle position of the bottom of the support plate, a sensor being provided on the left side of the nozzle, and electric cylinders being installed on both sides above the support plate. A rotating device includes fixed rollers, connecting columns, and a fixed frame. Fixed frames are installed on both sides below the support plate. Storage slots are installed on both sides inside the base. Fixed rollers are provided on both sides inside the storage slots and both sides inside the fixed frames. Connecting columns are installed on both sides of the outer walls of multiple fixed rollers. The right ends of the multiple connecting columns on the right side are installed inside the second bearings. The outer walls of the two upper second bearings are installed on the inner wall of the fixed frame, and the outer walls of the two lower second bearings are installed on the inner wall of the storage slots. Motors are installed on the left ends of the multiple connecting columns on the left side. The two upper motors are installed on the outer wall of the fixed frame, and the two lower motors are installed inside the storage slots. The two lower fixed rollers are located inside the connecting slots. The connecting slots are located on both sides of the top of the storage slots, and grooves are provided on both sides of the connecting slots.

[0006] Preferably, the base and the support plate are arranged parallel to each other, the nozzle is connected to the pipe body, electric valve and storage box, and the electric cylinders on both sides operate synchronously.

[0007] Preferably, the support plate and the fixed frame are fixedly connected, and the middle position of the fixed frame, the middle position of the two upper fixed rollers, and the middle position of the base are on the same horizontal line.

[0008] Preferably, the fixed roller and the connecting column are fixedly connected, and the connecting column on the right side is rotatably connected to the second bearing.

[0009] Preferably, the connecting column on the left side is fixedly connected to the output end of the motor.

[0010] Preferably, the two connecting posts at the top are T-shaped, and the connecting posts and the grooves are correspondingly positioned.

[0011] Preferably, the bottom of the connecting column and the upper fixed roller are not on the same horizontal line.

[0012] Preferably, the two upper fixed rollers and the two lower fixed rollers are arranged in a corresponding manner.

[0013] Preferably, the motor, sensor, electric cylinder, and electric valve connected to the nozzle are all electrically connected to the control box.

[0014] Preferably, the multiple motors operate synchronously, and the upper and lower fixed rollers operate relative to each other.

[0015] Compared with existing technologies, the beneficial effects of this utility model are: By employing precise spraying or multi-stage roller coating technology, the coating thickness can be stably controlled within an ultra-thin range of 0.01mm-0.1mm, ensuring rust prevention performance without affecting the dimensional accuracy of the nail wire.

[0016] Combined with the flattening and conveying mechanism, the flatness of the nail wire substrate is ensured, fundamentally avoiding defects such as uneven coating and dripping caused by uneven substrate, thus ensuring stable product quality.

[0017] It integrates flattening, conveying, positioning and coating functions, realizes continuous automated operation, can meet the requirements of high-speed production lines, and greatly improves production efficiency.

[0018] This invention limits the coating thickness to 0.01mm to 0.1mm because: If the coating is less than 0.01mm, it cannot form a continuous and dense protective layer, making it prone to pinholes and failing to meet rust prevention standards. If the coating is greater than 0.10mm, the cost increases, it affects the flexibility of the nail wire, and it may fail to form nails during winding and bending in the nail box. 0.01-0.1mm is the optimal range that balances corrosion resistance and flexibility.

[0019] The present invention limits the viscosity of the anti-rust coating to 15 seconds to 150 seconds because: when the viscosity is too low (<15s), the coating is prone to dripping and sagging, resulting in uneven paint film and poor edge coverage. When the viscosity is too high (>150s), the leveling properties are poor, the paint film surface is not smooth, orange peel effect may occur, and the requirements for spraying pressure or roller gap are too high.

[0020] This invention limits the flat wire's travel speed to 8 m / min to 50 m / min because: when the flat wire's travel speed is less than 8 m / min, the coating becomes too thick, resulting in dripping and unevenness; too slow a speed affects production capacity. Speeds greater than 50 m / min are too fast, leading to incomplete coating curing and missed areas. The instantaneous control precision required for coating and curing is extremely high; this speed range is the economically efficient range for continuous industrial production, ensuring the uniformity of coating thickness (tolerance controllable within ±0.005 mm).

[0021] The coating mechanism and method described in this invention are specifically designed to solve the rust prevention problem of the special stitching flat wire for cardboard boxes. Attached Figure Description

The outer wall is installed on the inner wall of the fixed frame 214, the outer walls of the two lower second bearings 209 are installed on the inner wall of the storage tank 213, the left end of the multiple connecting columns 208 on the left side is equipped with motors 210, the upper two motors 210 are installed on the outer wall of the fixed frame 214, the lower two motors 210 are installed inside the storage tank 213, the lower two fixed rollers 207 are located inside the connecting groove 211, the connecting groove 211 is located on both sides of the top of the storage tank 213, and the connecting groove 211 has grooves 212 on both sides.

[0031] The base 101 and the support plate 102 are arranged parallel to each other. The nozzle 103 is connected to the pipe body, electric valve and storage box. The electric cylinders 105 on both sides operate synchronously.

[0032] The support plate 102 is fixedly connected to the fixed frame 214. The middle position of the fixed frame 214, the middle position of the two upper fixed rollers 207, and the middle position of the base 101 are on the same horizontal line.

[0033] The fixed roller 207 is fixedly connected to the connecting column 208, while the right connecting column 208 is rotatably connected to the second bearing 209. The pressing pressure or rolling speed can be adjusted to ensure that the carton staple lines are aligned.

[0034] The left connecting post 208 is fixedly connected to the output end of the motor 210.

[0035] The two connecting posts 208 at the top are T-shaped, and the connecting posts 208 and the grooves 212 are correspondingly positioned.

[0036] The bottom of the upper connecting column 208 is not on the same horizontal line as the upper fixed roller 207.

[0038] The electric valves connected to the motor 210, sensor 104, electric cylinder 105, and nozzle 103 are all electrically connected to the control box.

[0039] Multiple motors 210 operate synchronously, and two fixed rollers 207 move relative to each other. Example

[0040] This embodiment provides a coating application module using contact roller coating, which can replace the spraying mechanism in Embodiment 1. It mainly includes: a paint tank, a pick-up roller immersed in the paint tank for carrying up the resistive paint, a metering transfer roller arranged parallel to the pick-up roller with an adjustable gap, and a coating roller parallel to the metering transfer roller and in contact with the flat wire.

[0041] During operation, the pick-up roller carries the resist paint out of the paint tank, passes through a precise gap with the metering transfer roller, scrapes off excess paint, and forms an extremely thin and uniform coating on the surface of the metering transfer roller. This coating is then transferred to a coating roller that rotates synchronously with the flat wire below, and is finally evenly pressed onto the surface of the flat wire by the coating roller. By precisely adjusting the gap and rotation speed between the rollers, precise control of the thickness from 0.01 mm to 0.1 mm can also be achieved. Its conveying, flattening, and positioning mechanisms are the same as in Example 1.

[0042] Working principle: First, place the special flat thread for the carton to be processed above the lower fixed roller 207, with the flat thread above the connecting groove 211 and between the positioning grooves 212. The position sensor 104 detects the position of the flat thread in real time. When the flat thread completely enters the designated area, it sends an "arrival signal" to the control box to trigger subsequent actions. After receiving the "position signal", the control box starts the electric cylinder 105. Its output end drives the fixed frame 214 below the support plate 102 and the upper fixed roller 207 to move downward synchronously. The connecting column 208 connected to the upper fixed roller 207 is precisely embedded in the positioning groove 212 to ensure that the axes of the upper and lower fixed rollers 207 are completely aligned to avoid roller pressure deviation. The upper and lower fixed rollers 207 clamp the flat line and press the flat line flat with constant pressure from the electric cylinder 105 to eliminate the wrinkles of the flat line and provide a flat base for subsequent spraying. After the roll is flattened, the control box starts the drive motor 210, which drives the upper and lower fixed rollers 207 to rotate synchronously in the opposite direction through the connecting column 208. The relative rotation of the upper and lower fixed rollers 207 generates friction, which drives the flat thread to be transported stably in a straight line, avoiding twisting of the paper flat thread. During the rotation, the electric cylinder 105 maintains constant pressure to ensure that the flat thread is always in a flat state during transport. Simultaneously with the start of the conveying process, the control box opens the electric valve of the spray nozzle 103, and the paint in the storage tank is conveyed to the nozzle 103 through the pipe to uniformly spray the moving flat wire. When the flat wire reaches the end, the position sensor 104 detects the "flat wire end signal", and the control box performs the following actions in sequence: closes the electric valve of the spray nozzle 103 to stop spraying; closes the roller drive motor 210 to stop conveying; controls the electric cylinder 105 to drive the upper fixed roller 207 to rise and reset, returning to the initial position. The processed flat wire is then discharged between the upper and lower fixed rollers 207, waiting for the next feeding cycle.
