Description

Technical Field

[0001] This utility model relates to the field of feeding technology for screed machines, specifically to an auxiliary feeding mechanism for an uncoiling screed machine. Background Technology

[0002] Automatic uncoiling and leveling machines are widely used in various material processing industries. Their main function is to uncoil and level rolls of material, providing a flat, wrinkle-free material surface for subsequent processing steps. This equipment is widely used in the processing of various materials such as metal, plastic, paper, and rubber, improving automation and efficiency in the production process. The working principle of an automatic uncoiling and leveling machine: An automatic uncoiling and leveling machine typically consists of three parts: an uncoiling mechanism, a leveling mechanism, and a control system. When the roll of material is placed on the uncoiling mechanism, the equipment automatically identifies the specifications and position of the roll, and then levels it through the leveling mechanism.

[0003] When the roll material is placed on the feeding rack, it is continuously fed by pressing the surface of the roll material with pressure rollers. As the thickness of the roll material decreases, the support arms on the feeding rack expand accordingly and come into contact with the inner wall of the roll material, generating friction. Due to the large gap between the support arms and the continuous decrease in the thickness of the roll material, when the pressure rollers press on the roll material at the position with the larger gap between the support arms, the roll material is easily dented and deformed due to its own weight, which affects the subsequent leveling effect.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing an auxiliary feeding mechanism for an uncoiling and leveling machine. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for an auxiliary feeding mechanism of an uncoiling and leveling machine. This solution avoids deformation and denting of the coil material due to the large gap between the two support arms and the downward pressure of the pressure roller as the coil material becomes thinner. It ensures that the weight of the pressure roller always acts on the surface of the filling arm or support arm to maintain the shape of the coil material, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: an auxiliary feeding mechanism for an uncoiling and leveling machine, including a frame, a pressure frame rotatably mounted on one upper surface of the frame, a pressure roller rotatably mounted on the bottom of the pressure frame, a feeding frame rotatably mounted on the other side of the top of the frame, and a cylinder mounted at the end of the feeding frame;

[0007] The surface of the feeding rack is fitted with a slidable sleeve, and a support arm is hinged to the surface of the sleeve via a hinge rod. A cross-shaped groove is formed on the surface of the feeding rack, and the sleeve is connected to the piston end of the cylinder through the cross-shaped groove. A fixed plate is fixed to the end of the feeding rack, and multiple circumferentially distributed sliding grooves are formed on the surface of the fixed plate. A connecting shaft II is fixed to the end of the support arm, and the connecting shaft II passes through the sliding groove and is slidably connected to the surface of the fixed plate. A spring III is fixed to the end of the connecting shaft II, and the spring III is located inside the sliding groove. Three filling arms are circumferentially distributed on the surface of the sleeve, and the filling arms are adjacent to the support arms. Sliding arms are slidably connected to both sides inside the support arms.

[0008] As a preferred embodiment of this utility model, the end of the filling arm is fixed with a connecting shaft I at the position of the fixed plate, the end of the connecting shaft I moves within one of the grooves of the fixed plate, and a spring IV is fixed on the surface of the connecting shaft I, with the spring IV located inside one of the grooves.

[0009] As a preferred embodiment of this utility model, the filling arm is hollow inside, and a connecting rod is fixed to one side of the sliding arm inside the hollow of the filling arm. A spring I is connected between the two connecting rods, and a sliding rod is rotatably connected between the two pressure frames.

[0010] As a preferred embodiment of this utility model, a rotating ring is rotatably connected to the surface of the fixed disk, and a slider II is fixed at the end of the connecting shaft I outside the fixed disk. The inner wall of the rotating ring contacts the slider II through a protrusion during rotation.

[0011] As a preferred embodiment of this utility model, an arc-shaped groove is provided on the middle surface of the filling arm, the arc-shaped groove is connected to the interior of the filling arm, and a slider I is fixed on the surface of the connecting rod at a position opposite to the arc-shaped groove.

[0012] As a preferred technical solution of this utility model, the arc-shaped groove has a limiting groove II on both sides. When the slider I slides inside the arc-shaped groove, it contacts the limiting groove II. The limiting groove II has multiple insertion holes. The slider I has insertion blocks elastically connected to both sides inside by springs II. The insertion blocks fix the distance between the sliding arm and the filling arm by inserting into the insertion holes.

[0013] As a preferred embodiment of this utility model, the two ends of the slide rod extend to the outer sides of the frame through the limiting groove I, and the two ends of the slide rod are fitted with sleeve rods, with the middle of the sleeve rods connected to the motor.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By sliding slider I, the sliding arm moves outward to both sides of the filling arm to extend the length of the filling arm, so as to fill the gap between the two support arms. This prevents the roll material from being deformed and dented due to the large gap between the two support arms as it gets thinner. This ensures that the weight of the pressure roller always acts on the surface of the filling arm or support arm to maintain the shape of the roll material.

[0016] 2. By using a motor to drive the lifting rod, the part of the pressure frame near the motor can be adjusted according to the thickness of the roll material. This prevents the pressure roller from pressing on the roll material surface when the height of a thicker roll material is close to that of the pressure frame, thus reducing the pressing effect of the pressure roller.

[0017] 3. The sliding arm is driven by slider I to slide inside the arc groove, and the insertion block is connected to the insertion hole inside the limiting groove II to fix the distance of the sliding arm. When the support arm is retracted, the distance between them will decrease. The sliding arm is fully retracted by sliding inside the filling arm, so that the support arm and the filling arm form a circular structure when stored, so as to avoid obstruction when the support arm is stored.

[0025] 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.

[0026] Example 1

[0027] Please see Figure 1-6 As shown, an auxiliary feeding mechanism for an uncoiling and leveling machine includes a frame 1, a pressure frame 2 rotatably mounted on one side of the upper surface of the frame 1, a pressure roller 201 rotatably mounted on the bottom of the pressure frame 2, and a feeding frame 307 rotatably mounted on the other side of the top of the frame 1, with a cylinder 308 mounted at the end of the feeding frame 307.

[0028] The surface of the feeding rack 307 is fitted with a sliding sleeve 303. The surface of the sleeve 303 is hinged to a support arm 310 via a hinge rod. The surface of the feeding rack 307 has a cross-shaped groove. The sleeve 303 is connected to the piston end of the cylinder 308 via the cross-shaped groove. The end of the feeding rack 307 is fixed with a fixed plate 3. The surface of the fixed plate 3 has multiple circumferentially distributed sliding grooves. The end of the support arm 310 is fixed with a connecting shaft II 309. The connecting shaft II 309 passes through the sliding groove and is slidably connected to the surface of the fixed plate 3. The end of the connecting shaft II 309 is fixed with a spring III 306. The spring III 306 is located inside the sliding groove. The surface of the sleeve 303 has three filling arms 301 distributed circumferentially. The filling arms 301 are adjacent to the support arm 310. The two sides of the support arm 310 are slidably connected with sliding arms 302.

[0029] A connecting shaft I 305 is fixed at the end of the filling arm 301 at the position of the fixed plate 3. The end of the connecting shaft I 305 moves within one of the grooves of the fixed plate 3. A spring IV 313 is fixed on the surface of the connecting shaft I 305 and is located inside one of the grooves. The filling arm 301 is hollow inside. A connecting rod 311 is fixed on one side of the sliding arm 302 inside the hollow of the filling arm 301. A spring I is connected between the two connecting rods 311. A sliding rod 203 is rotatably connected between the two pressure frames 2. A rotating ring 312 is rotatably connected to the surface of the fixed plate 3. A slider II 314 is fixed at the end of the connecting shaft I 305 outside the fixed plate 3. The inner wall of the rotating ring 312 contacts the slider II 314 through a protrusion when rotating.

[0030] The roll material is fitted onto the surface of the support arm 310, and then the pressure frame 2 is rotated in the opposite direction so that the pressure roller 201 contacts and presses the surface of the roll material. The roll material is then fed and leveled by the pressure roller 201. Since the roll material diameters vary, the cylinder 308 can be driven to push the sleeve 303 closer to the fixed plate 3 during the loading process. The support arm 310 gradually rises via the hinge rod, expanding until it contacts the inner wall of the roll material to fix it in place. Because the roll material becomes thinner during loading and leveling, and the distance between the two support arms 310 is relatively large, to prevent the pressure roller 201 from being easily dented and deformed by the pressure at the distance between the two support arms 310 due to gravity, the rotating ring 312 can be rotated to allow the inner wall of the rotating ring 312 to... The protrusion separates from the surface of slider II 314. Slider II 314 expands due to the deformation generated by spring IV 313, pushing slider II 314 and filling arm 301 towards the middle position of sleeve 303 away from fixed plate 3, so that filling arm 301 expands to be flush with support arm 310. Then, sliding slider I 3012 drives its sliding arm 302 to move outward to both sides of filling arm 301 to extend the length of filling arm 301, so as to fill the gap between the two support arms 310. This prevents deformation and denting caused by the large gap between the two support arms 310 due to the pressure of the pressure roller 201 when the coil feed becomes thinner. This ensures that the gravity of the pressure roller 201 always acts on the surface of filling arm 301 or support arm 310 to maintain the shape of the coil.

[0031] The contact and separation between the pressure block on the inner wall of the rotating ring 312 and the slider II 314 can be adjusted according to the diameter of the roll material. Furthermore, when the sliding arm 302 moves inside the filling arm 301, it can be adjusted according to the spacing between the filling arms 301 to suit its use.

[0032] Example 2

[0033] Please see Figure 1 and 6As shown in the figure, in a specific embodiment of the present invention, an arc-shaped groove 3011 is formed on the middle surface of the filling arm 301. The arc-shaped groove 3011 communicates with the interior of the filling arm 301. A slider I 3012 is fixed at a position opposite to the arc-shaped groove 3011 on the surface of the connecting rod 311. Limiting grooves II 3013 are formed on both sides of the arc-shaped groove 3011. When the slider I 3012 slides inside the arc-shaped groove 3011, it contacts the limiting grooves II 3013. Multiple insertion holes are formed inside the limiting grooves II 3013. Insert blocks 3014 are elastically connected to both sides of the slider I 3012 through springs II 3015. The insert blocks 3014 fix the distance of the sliding arm 302 sliding inside the filling arm 301 by inserting into the insertion holes. The two ends of the slide rod 203 extend to the outside of both sides of the frame 1 through the limiting grooves I 204 respectively. The two ends of the slide rod 203 are fitted with sleeve rods 202. The middle of the sleeve rods 202 is connected to the motor.

[0034] The sleeve rod 202 is driven by a motor to rise and fall, and the slide rod 203 rises and falls in the same direction as the sleeve rod 202. When the slide rod 203 is raised and lowered, it is rotatably connected to the pressure frame 2, causing part of the pressure roller 201 to tilt downward and press on the surface of the roll material. The part of the pressure frame 2 near the motor can be adjusted according to the thickness of the roll material. This avoids reducing the pressure of the pressure roller 201 on the surface of the roll material when the height of the thicker roll material is close to that of the pressure frame 2, thus preventing a reduction in the downward pressing effect of the pressure roller 201.

[0035] The slider I 3012 drives the sliding arm 302 to slide inside the arc groove 3011, and the insert block 3014 is inserted into the insertion hole inside the limiting groove II 3013 to fix the distance of the sliding arm 302. When the support arm 310 is retracted, the distance between them will decrease. The sliding arm 302 slides inside the filling arm 301 to completely retract it, so that when the support arm 310 is stored, it forms a circular structure with the filling arm 301, avoiding obstruction when the support arm 310 is stored.
