Description

Technical Field

[0001] The present invention relates to the technical field of plastic bag processing, and specifically relates to a shearing and guiding device for plastic packaging bags. Background Art

[0002] In an automated plastic bag production system, the stacked continuous cutting process is a core link affecting product quality. Existing technologies usually use a single-sided fixture to fix stacked plastic bags and convey them along a smooth workbench to the shearing station. When the fixture applies a normal pressure only to one side of the stacked plastic bags and the other side is in a free state, under the action of the shearing force, a non-linear stress field is formed inside the stack. The shearing stress on the free side is higher than that on the clamped side, causing relative slip between layers.

[0003] Flexible materials such as low-density polyethylene are prone to micro-curling at the unconstrained edge, resulting in deviation of the cutting plane inclination angle. When a rotating cutter roller or a reciprocating cutter contacts the material, the instantaneous pressure will cause elastic compression in the thickness direction of the stack. After the cutter leaves, the inconsistent springback leads to layer misalignment. The cutting force forms a shear wave in the material, and the amplitude of the free side is higher than that of the clamped side, exacerbating the formation of wrinkles.

[0004] Existing technologies use grooves on the workbench surface or vacuum adsorption, but they cannot solve the stress concentration problem during the dynamic cutting process. As a result, during high-speed cutting in the existing process, the perpendicularity error increases, leading to an increase in the defective rate. Therefore, a shearing and guiding device for plastic packaging bags is proposed to solve the above-mentioned problems. Summary of the Invention

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a shearing and guiding device for plastic packaging bags, having the following beneficial effects: 1. For the shearing and guiding device of the plastic packaging bag, the device drives the gear and rack mechanism through the motor of the guiding part, so that the rotating roller applies an adjustable tension to the free side of the plastic bag, forming a dynamic balance with the unilateral pressure of the clamping part, effectively offsetting the non-linear stress field inside the stacked body, reducing the relative slip amount between layers, and solving the dislocation problem caused by excessive shearing stress on the free side.

[0016] 2. For the shearing and guiding device of the plastic packaging bag, the anti-warping plate of the anti-crease part cooperates with the guiding plate through the inclined ear end, slightly curls and flattens the edge of the free side of the plastic bag before cutting, and cooperates with the elastic support structure of the arc piece and the telescopic rod to adapt to the edge characteristics of different materials, reducing the deviation of the inclination angle of the cutting plane and improving the verticality accuracy of the cut.

[0017] 3. For the shearing and guiding device of the plastic packaging bag, the combination of the spring and the telescopic rod of the anti-crease part can absorb the energy of the shear wave generated during cutting in real time. The hinged structure of the anti-warping plate allows small swings, reducing the amplitude of the free side, effectively suppressing the formation of wrinkles caused by inconsistent elastic compression and rebound during the cutting process, and improving the qualified rate of the cut error.

[0018] 4. For the shearing and guiding device of the plastic packaging bag, the tension part driven by the motor can dynamically adjust the roller pressure through the feedback of the torque sensor, and cooperate with the elastic flattening mechanism of the anti-crease part, which can be compatible with plastic bag stacked bodies of different thicknesses and different elastic moduli without manual intervention, solving the problem that traditional fixed-pressure clamps are sensitive to material properties.

[0019] 5. For the shearing and guiding device of the plastic packaging bag, after cutting is completed, the rack drives the anti-warping plate to rise obliquely along the guiding plate. Through the composite trajectory of vertical and inclined movements, it avoids excessive extrusion and friction with the surface of the plastic bag. At the same time, the detachable anti-crease part structure is convenient for cleaning and maintenance, reducing the risk of mechanical jamming caused by dust accumulation and extending the service life of the equipment.

[0026] It is worth noting that moving slide blocks 2 are symmetrically installed at both ends of the front crossbeam 1. The moving slide blocks 2 are used to connect the linear motors on both sides of the shearing table to perform reciprocating loading and unloading operations. A clamping portion 3 is provided on the moving slide block 2 for normally clamping and pulling the stacked plastic bags. The clamping portion 3 includes a rotating rod 31, which is fixedly connected between the two moving slide blocks 2. A clamp 32 is installed on the rotating rod 31. A pressure head 33 is fixedly connected to the bottom surface of the end of the clamp 32. A pressure plate 34 corresponding to the pressure head 33 is fixedly connected to the bottom of the front crossbeam 1. The middle of the outer wall of the rotating rod 31 is fixedly connected to the The fixed sleeve is provided with a hinge plate 35, a hinge block 36 is hinged on the hinge plate 35, an electric push rod 37 is provided on the hinge block 36, the movable end of the electric push rod 37 is fixedly connected to the hinge block 36, and a mounting portion 7 is provided on the movable slider 2. The mounting portion 7 includes a rear cross beam 71, a rod hole is opened in the middle of the top of the rear cross beam 71, and the movable end of the electric push rod 37 is movably arranged on the inner wall of the rod hole. Three reinforcement plates 72 are fixedly connected to the back side of the rear cross beam 71, and brackets 73 are fixedly connected to the three reinforcement plates 72. A support block is installed on the bracket 73, and the electric push rod 37 is installed on the support block.

[0027] Working principle: the moving slider 2 is driven by a linear motor to drive the clamping part 3 to move above the stacked plastic bags. The electric push rod 37 extends and drives the rotating rod 31 to rotate through the hinge plate 35 and the hinge block 36, so that the pressure head 33 of the clamp 32 presses one side of the plastic bag, such as the left side, and cooperates with the pressure plate 34 to form a single-sided fixation, which is similar to the single-sided pneumatic clamp of South Korea's SUNGIL MACHINERY, but the pressure is dynamically adjustable through the electric push rod 37 to adapt to stacks of different thicknesses.

[0028] The motor 47 on the machine baffle 46 is started, driving the gear 48 to rotate. Since the gear 48 is meshed with the rack 51, and the sleeve 42, the guide groove 44 and the rack 51 are all inclined, the rack 51 slides downward in an oblique direction, driving the roller 53 to press against the free side of the plastic bag, such as the right side. The speed of the motor 47 determines the moving speed of the rack 51, thereby controlling the pressure of the roller 53 on the free side, which can be adjusted through feedback from the torque sensor to form a tension balance with the clamping side.

[0029] When the rack 51 moves, the anti-rocking plate 63 of the anti-fold part 6 moves obliquely with the rack 51, and its inclined ear end contacts the free side edge of the plastic bag. The edge is slightly curled and flattened through the elastic support of the connecting rod 61 and the telescopic rod 64. When the material of the plastic bag changes, the telescopic rod 64 automatically adjusts the flattening force through the spring 67 to avoid material deformation caused by excessive extrusion. The hinged structure of the arc piece 65 and the connecting plate 66 allows the anti-rocking plate 63 to swing slightly with the fluctuation of the cutting force, absorb the shear wave energy generated during cutting, and reduce the amplitude of the free side.

[0030] The cutting adopts the shearing device in the plastic bag processing machinery of the prior art. The plastic bag is dragged under the shearing device, and the roller 53 moves to beyond the free side of the plastic bag. At this time, the plastic bag is still pressed by the anti-rocking plate 63, and the free side of the plastic bag will not be hindered during shearing, so as to achieve normal plastic bag opening cutting. After the cutting is completed, the motor 47 is reversed, and the rack 51 slides upward along the guide groove 44, and the roller 53 is separated from the free side of the plastic bag. At the same time, the ear end of the anti-rocking plate 63 preferentially contacts the obtuse inclined end of the guide plate 49, thereby causing the anti-rocking plate 63 to rise along the guide plate 49. At this time, the rise of the rack 51 drives the anti-rocking plate 63 to rise synchronously, causing the anti-rocking plate 63 to produce two synchronous movements with vertical rising and inclined rising trends, thereby realizing that the anti-rocking plate 63 is away from the surface of the stacked plastic bags, and no excessive squeezing and damage to the plastic bags occurs. At the same time, under the action of the spring 67, the telescopic rod 64 contracts and flips over to reset.

[0031] After resetting, the roller 53 is suspended above the clamp 32, the electric push rod 37 is retracted, the rotating rod 31 rotates in the opposite direction, the clamp 32 is lifted, and a cutting cycle is completed. The stacked body is transported to the next station by the conveyor belt.
