Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roll material processing equipment, in particular to a roll material automatic feeding mechanism, which is suitable for automatic feeding of various cylindrical roll materials (such as plastic rolls, metal rolls, paper rolls, etc.), and can be used with roll material processing production lines, detection equipment, etc., to realize continuous and stable feeding of roll materials. BACKGROUND

[0002] In the production and processing process of roll materials, the feeding process directly affects the production efficiency and product quality. The current mainstream feeding method in the industry is manual feeding: the operator needs to manually carry the roll material to the conveying device or processing station, which has the following defects: 1) high labor intensity, repeated carrying hundreds of times per shift, which easily leads to personnel fatigue; 2) low feeding efficiency, limited carrying capacity per time by manual operation, which is difficult to match the production line rhythm; 3) poor positioning accuracy, manual placement easily leads to roll material deviation, affecting the subsequent processing accuracy; 4) high safety risk, roll material falling easily causes equipment damage or personnel injury.

[0003] Although some existing roll material feeding mechanisms attempt to solve the above problems, they still have obvious deficiencies: first, the spacing of the conveying assembly is fixed, which is only suitable for a single specification of roll material, and the roll material type needs to be re-adjusted when changing the roll material, which has poor universality; second, the feeding assembly often uses a cylinder pushing or rigid push piece structure, which easily causes hard collision when contacting the roll material, resulting in scratches on the surface of the roll material, and the pushing track is easily deviated, with a high jamming rate of 5%-10%; third, the conveying assembly lacks a guide structure, which is easily deformed after long-term use, resulting in deviation of the roll material conveying track and poor feeding stability.

[0081] Specification adjustment: according to the length of the to-be-loaded roll material, such as the length of 1000mm, the operator rotates the distance adjusting hand wheel 3 clockwise or counterclockwise to drive the lead screw 18 to rotate; since the rotation directions of the two sections of threads of the lead screw 18 are opposite, the two adjusting plates 15 drive the fixing plates 7 to move away from or towards each other along the slide rail 11, until the distance between the fixing plates 7 is 1020mm with 20mm gap reserved, and the hand wheel is stopped;

[0082] Roll material feeding: the roll material to be fed, such as a plastic roll with a diameter of 200 mm and a length of 1000 mm, is placed on the inclined top surface of the feeding metal plate 19, and the roll material automatically rolls into the chute 4 along the inclined surface under the action of its own gravity, is guided into the V-shaped groove 8 of the fixed plate 7, and the V-shaped groove 8 positions the roll material;
