Description

Technical Field

[0001] The utility model relates to an automatic feeding device, in particular to an automatic film feeding device for a rubber track steel belt rubberizing machine. Background Art

[0002] Rubber tracks are mainly used for special occasions, such as tanks and armored vehicles in military parades, to protect the ground. The rubber track walking system has low noise, small vibration, and comfortable ride. It is particularly suitable for occasions with high-speed transfers and achieves all-road passability. Advanced and reliable electrical instruments and machine status monitoring systems provide a reliable guarantee for the driver to operate correctly. In addition to military applications, it is also widely used in large machinery, such as tracked vehicles such as excavators, with the same functionality and role. In order to increase strength, a steel wire layer is set inside the rubber track. The formation of the track is formed by wrapping a laminated rubber layer around the steel wire layer.

[0003] The applicant has previously applied for a track steel wire rubber coating machine with a publication number of CN112519285B, which includes a frame, on which two support rollers for supporting the track are arranged at intervals, and between the two support rollers there is a binding roller and two folding rollers, the binding roller is parallel to the support roller and has two annular baffles coaxially arranged with the binding roller, the two folding rollers are adjacent and in a V shape with the opening facing upwards, and the binding roller can move downward to a position adjacent to the folding roller so that the inner sides of the two annular baffles and the inner sides of the two folding rollers can both contact the two sides of the track. In this way, one-sided rubber coating is achieved and the laminating effect of the track tape is ensured.

[0004] When using the above crawler steel wire rubber coating machine for rubber coating, the required film is mostly manually loaded, that is, the person needs to continuously step on the foot switch and continuously pull the film to feed the film into the crawler steel wire rubber coating machine. The above film loading process is labor-intensive and inefficient, and there is a possibility that the film may be torn.

[0005] Therefore, the applicant continued to research and develop based on the above-mentioned track wire rubber coating machine, striving to improve the process steps of film feeding, reduce manual labor intensity, improve production efficiency, and avoid human damage to the film during the feeding process.

[0011] Furthermore, the mounting frame is provided with a clamping mechanism; the clamping mechanism comprises a slide and a clamping claw. With this structure, the clamping claw can clamp the cut film and, under the action of the slide, transport the film to the rubber-wrapping machine for the next rubber-wrapping operation; the automation of the device is further improved and the labor intensity of the workers is reduced. Furthermore, the slide and the clamping claw are both pneumatic structures. The slide and the clamping claw with pneumatic structures can share an air source assembly with the lifting cylinder (53).

[0025] In this embodiment, the automatic film feeding device for the rubber track steel belt rubber wrapping machine further includes a cutting mechanism 5; the cutting mechanism 5 includes a mounting frame 51, a cutting knife 52, a lifting cylinder 53 and a pair of pressing wheels 54; the mounting frame 51 can be mounted and fixed on the external rubber wrapping machine 6; the cutting knife 52 is arranged on the mounting frame 51, and can cut the film 32 under the action of the lifting cylinder 53; the pressing wheel 54 is arranged on the mounting frame 51, and can clamp the film 32 under the action of the lifting cylinder 53 during cutting. With this structure, the cutting knife 32 can automatically cut the film 32 under the action of the lifting cylinder 53, further improving the automation of the device and reducing the labor intensity of workers.

[0026] In this embodiment, the mounting frame 51 is provided with a clamping mechanism 7, which includes a slide 71 and a clamping mechanism 72. With this structure, the clamping mechanism 72 can clamp the cut film 32, and under the action of the slide 71, the film 32 is transported to the rubber-wrapping machine 6 for the next rubber-wrapping operation, which further improves the automation of the device and reduces the labor intensity of workers.

[0027] In this embodiment, the slide 71 and the clamp 72 are both pneumatic structures. The slide 71 and the clamp 72 with pneumatic structures can share an air source assembly with the lifting cylinder 53.

[0028] In this embodiment, the thin film unwinding assembly 12 further includes a magnetic powder brake 122, which is in driving connection with the unwinding wheel 121. With this structure, the unwinding wheel 121 can unwind the film 32 in a constant tension manner, thereby avoiding the situation where the film 32 is stretched due to unwinding too fast or unwinding too slowly, thereby improving the reliability of the device.

The B driving component 223 drives the fifth rubber storage wheel 221 to rotate, causing the film 32 to start hanging. First, fill up the fifth rubber storage wheel 221 (that is, when the limit sensor 4 detects the film 32), and the fifth rubber storage wheel 221 stops rotating after being filled; then the fourth rubber storage wheel 221 repeats the above steps to start hanging the film 32 until all the rubber storage wheels 221 are filled. During operation, the worker first pulls the film 32 to the clamping jaw 72, the clamping jaw 72 clamps the film 32, and under the action of the sliding table 71, the film 32 is conveyed into the rubberizing machine 6 (at this time, the 5 rubber storage wheels 221 will automatically operate according to the feedback of the limit sensor 4 and convey the film 32 in a timely manner to achieve the purpose of automatic feeding); the clamping jaw 72 releases the film 32 and retracts to the initial position. At this time, the film 32 continues to move under the drive of the rollers in the rubberizing machine 6. When the encoder and the length meter in the rubberizing machine 6 feedback that the film 32 reaches the specified amount, the lifting cylinder 53 drives the pressing wheel 54 and the cutting knife 52 to rise to cut the film 32 (when cutting, the pressing wheel 54 can clamp the film 32 to prevent the film 32 from falling), the clamping jaw 72 clamps the film 32, the lifting cylinder 53 drives the pressing wheel 54 and the cutting knife 52 to descend, and waits for the sliding table 71 to receive the movement instruction, then the next rubberizing operation can be carried out.
