Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly packaging material roll processing technology, and in particular to an environmentally friendly packaging material roll replacement device. Background Technology

[0002] In the continuous production of environmentally friendly packaging materials, frequent roll changes are necessary to ensure operational continuity. Traditional roll changing relies heavily on manual handling of the rolls to the machine frame interface. This not only results in laborious operation and low roll changing efficiency due to the heavy weight of the environmentally friendly material rolls, but also easily leads to material damage and waste due to human misalignment. Some semi-automatic devices have complex structures and poor adaptability, only supporting single-specification rolls, and lack stable limiting and buffering designs. During roll changing, the impact of the roll can easily damage the end shaft or substrate, making it difficult to meet the requirements of efficient and low-loss environmentally friendly packaging production. Therefore, there is an urgent need for a convenient, adaptable, safe, and efficient environmentally friendly packaging material roll changing device.

[0003] Patent CN217626663U discloses an environmentally friendly packaging material roll changing device, comprising three parts: a frame, a roll changing assembly, and a limiting assembly. The frame is a two-column structure with a roll card interface on one side of its top for fixing the two end shafts of the roll, and a mounting block on the same side of its bottom. The roll changing assembly includes a rotating shaft and a support frame. The rotating shaft is rotatably mounted on the mounting block, and the support frame is fixed to the rotating shaft. A support opening is provided at the top of the support frame, and the two end shafts of the roll are simultaneously installed in the support opening. This invention simplifies the roll changing process by using a novel roll changing structure with a limiting assembly comprising a driving component and a limiting post. The driving component is mounted on the top of the frame, and the limiting post extends through the frame into the roll card interface.

[0004] While existing environmentally friendly packaging material roll changing devices employ a novel roll-changing structure with a limiting component including a drive unit and a limiting post—the drive unit mounted on top of the frame and the limiting post extending through the frame into the roll card interface—to simplify the roll-changing process, they face numerous prominent problems in practical use. In terms of operation, the roll-changing efficiency is low and the operation is labor-intensive. The roll-changing process requires manual rotation of the support frame to ground level to place or remove the roll. For heavier rolls, single-person operation is extremely difficult, increasing not only the labor intensity of workers but also prolonging the roll-changing time, making it difficult to adapt to high-frequency production demands. Furthermore, in production scenarios requiring the handling of various packaging material specifications, the poor equipment versatility becomes particularly apparent. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative environmentally friendly packaging material roll changing device to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly packaging material roll changing device, which solves the problems of low roll changing efficiency and laborious operation. The roll changing process requires manual rotation of the support frame to ground height to place or remove the roll. For heavy rolls, it is extremely difficult for a single person to operate, which not only increases the labor intensity of the workers, but also prolongs the roll changing time. It is difficult to adapt to the high-frequency production needs. At the same time, the problem of poor equipment versatility will be particularly obvious in production scenarios that need to handle packaging materials of various specifications.

[0006] To achieve the above objectives, this utility model provides an environmentally friendly packaging material roll replacement device, including a lifting assembly. The lifting assembly includes a square base, with an installation hole at the center of the upper surface of the square base. A first hydraulic column is fixedly connected to the inner wall of the installation hole, and a lifting plate is fixedly connected to the output end of the first hydraulic column. A concave placement block is fixedly connected to the upper surface of the lifting plate, and a material roll body is movably connected to the upper surface of the concave placement block.

[0007] The material roll body has an internally fixed installation cylinder, and an installation column is movably connected to the inner wall of the left end of the installation cylinder. A positioning installation plate is fixedly connected to the left side surface of the installation column, and the bottom side surface of the positioning installation plate is fixedly connected to the side surface of the square base.

[0008] The square chassis has four fixedly connected limit rods at the four corners of its upper surface. The side surfaces of the limit rods are movably connected through the four corners of the lifting plate, and the tops of the four limit rods are fixedly connected to circular limit plates.

[0009] The square chassis has an adjustable clamping assembly on its right side surface. The adjustable clamping assembly includes two square support columns, which are positioned correspondingly. A clamping column is movably connected between the two square support columns. A circular support block is fixedly connected to the inner surface of the clamping column. The side surface of the circular support block is movably connected to the inner wall of the right end of the mounting cylinder.

[0010] The square support column has a second hydraulic column fixedly connected to its bottom side surface, and the end side surface of the second hydraulic column is fixedly connected to the inside of the square chassis. The bottom end of the square support column has an installation port, and a roller is fixedly connected to the inner wall of the installation port.

[0011] The square support column has a strip-shaped limiting plate fixedly connected to its outer surface. Both ends of the strip-shaped limiting plate have movably penetrating limiting columns. The right end of the limiting column is fixedly connected to a limiting strip, and the left end of the limiting column is fixedly connected to the outer surface of the square support column.

[0012] This utility model relates to an environmentally friendly packaging material roll replacement device. 1. In this utility model, the lifting plate driven by the first hydraulic column drives the concave placement block to rise and fall, which can automatically transport the material roll body to the appropriate height. With the help of the mounting column on the positioning mounting plate and the circular support block of the adjusting clamping component, the positioning and fixing of the material roll can be completed automatically. There is no need for manual handling or lifting of the material roll throughout the process, which effectively reduces the intensity of manual labor and avoids damage to the material roll caused by manual operation, significantly improving the efficiency of roll changing and the safety of operation.

[0013] 2. In this utility model, the two square support columns can be moved along the square base by the second hydraulic column, thereby adjusting the spacing between the circular support blocks, which can adapt to installation cylinders of different lengths; the arc structure of the concave placement block can adapt to the outer wall of the material roll within a certain diameter range, and the cooperation between the limiting rod and the lifting plate can stably support material rolls of different weights. It can meet the replacement needs of various specifications of material rolls without replacing special parts, thus improving the versatility of the device. Attached Figure Description

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-5An environmentally friendly packaging material roll replacement device includes a lifting assembly 1. The lifting assembly 1 includes a square base 101. An installation hole 102 is formed at the center of the upper surface of the square base 101. A first hydraulic column 103 is fixedly connected to the inner wall of the installation hole 102. A lifting plate 104 is fixedly connected to the output end of the first hydraulic column 103. A concave placement block 107 is fixedly connected to the upper surface of the lifting plate 104. A material roll body 108 is movably connected to the upper surface of the concave placement block 107. An installation cylinder 111 is fixedly passed through the inside of the material roll body 108. An installation column 109 is movably connected to the inner wall of the left end of the installation cylinder 111. A positioning installation plate 110 is fixedly connected to the left side surface of the installation column 109. The bottom side surface of the positioning installation plate 110 is fixedly connected to the side surface of the square base 101. Limiting rods 105 are fixedly connected to the four corners of the upper surface of the square chassis 101. The side surfaces of the limiting rods 105 extend through the four corners of the lifting plate 104. Circular limiting plates 106 are fixedly connected to the top of each of the four limiting rods 105. In the initial state, the first hydraulic column 103 is in a retracted state, driving the lifting plate 104 down to the lowest position along the limiting rods 105 at the four corners of the upper surface of the square chassis 101. At this time, the concave placement block 107 is synchronously in a low position with the lifting plate 104, making it convenient for the operator to place the material roll body 108 to be replaced on the arc-shaped bearing surface of the concave placement block 107. The concave structure is used to achieve initial limiting of the material roll body 108, preventing lateral displacement during placement. Once the material roll body 108 is in place, the first hydraulic column 103 is activated, and its output end extends upward along the axial direction of the mounting hole 102, driving the lifting plate 104 to rise steadily along the axial direction of the limiting rod 105. The limiting rod 105 and the lifting plate 104 are in a continuous and coordinated manner, which can effectively limit the lateral displacement of the lifting plate 104 during the lifting process. At the same time, the circular limiting plate 106 at the top can prevent the lifting plate 104 from detaching from the limiting rod 105 due to excessive lifting, thus ensuring the stability of the lifting process. As the lifting plate 104 rises, the mounting cylinder 111, which is fixed and penetrates the inside of the material roll body 108, rises synchronously until the inner wall of the left end of the mounting cylinder 111 is aligned with the mounting column 109 fixed on the positioning mounting plate 110. The first hydraulic column 103 continues to drive the lifting plate 104 to rise, so that the mounting column 109 gradually inserts into the inner wall of the left end of the mounting cylinder 111, completing the positioning support of the material roll body 108 on the left side of the axial direction. At this time, the material roll body 108 achieves stable installation through the cooperation of the mounting cylinder 111 and the mounting column 109, as well as the bearing of the concave placement block 107, and can then enter the subsequent material feeding operation state. When it is necessary to replace the material roll, it is only necessary to control the first hydraulic column 103 to retract, so that the mounting cylinder 111 is disengaged from the mounting column 109, and the lifting plate 104 drives the old material roll to a low position and removes it. Repeating the above steps can complete the replacement of the new material roll.

[0023] Please see Figures 1-5Based on the first embodiment, an adjusting clamping assembly 2 is provided on the right side surface of the square chassis 101. The adjusting clamping assembly 2 includes two square support columns 201, which are positioned correspondingly. A clamping column 206 is movably connected between the two square support columns 201. A circular support block 202 is fixedly connected to the inner surface of the clamping column 206. The side surface of the circular support block 202 is movably connected to the inner wall of the right end of the mounting cylinder 111. A second hydraulic column 208 is fixedly connected to the bottom side surface of the square support column 201. The end side surface of the second hydraulic column 208 is fixedly connected to the inside of the square chassis 101. An installation port 207 is opened at the bottom end of the square support column 201. A roller 209 is fixedly connected to the inner wall of the installation port 207. A strip-shaped limiting plate 203 is fixedly connected to the outer surface of the square support column 201. Both ends of the strip-shaped limiting plate 203 are movably connected to the limiting column 204. The right end of the limiting column 204 is fixedly connected to the limiting strip 205, and the left side surface of the limiting column 204 is fixedly connected to the outer surface of the square support column 201. When the first hydraulic column 103 in the lifting assembly 1 drives the lifting plate 104 to rise, it drives the material roll body 108 and its internal mounting cylinder 111 to rise to the preset height. When the left end of the mounting cylinder 111 is about to dock with the mounting column 109, the adjusting clamping assembly 2 starts synchronously: First, it controls the second hydraulic column 208 to move. Since its end is fixed inside the square chassis 101 and its output end is fixedly connected to the bottom of the square support column 201, the extension and retraction of the second hydraulic column 208 can push the two corresponding square support columns 201 to move along the right side surface of the square chassis 101. The bottom end of the square support column 201 contacts the square chassis 101 through the roller 209 fixed on the inner wall of the mounting port 207, converting sliding friction into rolling friction, reducing the resistance when the square support column 201 moves, and ensuring that its movement is smooth and stable. During the movement of the square support column 201, the strip-shaped limiting plate 203 fixed on its outer surface moves along with it. The limiting columns 204, which are movable through both ends of the strip-shaped limiting plate 203, slide synchronously along their own axial direction. The left end of the limiting column 204 is fixed to the outer surface of the square support column 201, and the right end is fixed to the limiting strip 205. Through the cooperation between the limiting column 204 and the strip-shaped limiting plate 203, the movement direction of the square support column 201 is restricted to prevent it from shifting laterally. At the same time, the limiting strip 205 can prevent the strip-shaped limiting plate 203 from detaching from the limiting column 204, thus ensuring the structural stability of the adjusting clamping assembly 2.When the square support column 201 moves to the target position, the clamping column 206, which is movably connected between the two square support columns 201, moves synchronously, causing the circular support block 202 fixed on the inner surface of the clamping column 206 to approach the right end of the mounting cylinder 111 until the side surface of the circular support block 202 inserts into the inner wall of the right end of the mounting cylinder 111 and fits tightly against the inner wall. At this time, the material roll body 108 forms a bidirectional axial positioning through the mounting column 109 at the left end and the circular support block 202 at the right end. At the same time, with the bearing effect of the concave placement block 107 in the lifting assembly 1, the material roll body 108 is stably installed, which can meet the coaxiality requirements of the material roll rotation in subsequent feeding operations. When it is necessary to replace the material roll, first control the second hydraulic column 208 to retract, which will drive the square support column 201 to move in the opposite direction, so that the circular support block 202 will detach from the inner wall of the right end of the mounting cylinder 111; then control the first hydraulic column 103 to retract, which will drive the lifting plate 104 to lower the old material roll to the low position. After removing the old material roll, repeat the above lifting and clamping adjustment steps to complete the replacement and fixing of the new material roll.

[0024] Working principle: In the initial state, the first hydraulic column 103 is in the retracted state, and the lifting plate 104 is in the low position along the limiting rod 105, placing the material roll body 108 to be replaced on the concave placement block 107. The mounting cylinder 111 inside is synchronously positioned with the material roll body 108. The first hydraulic column 103 is activated, driving the lifting plate 104 to rise steadily along the limiting rod 105, driving the material roll body 108 and the mounting cylinder 111 to rise synchronously until the left end of the mounting cylinder 111 is aligned with the mounting column 109 on the positioning mounting plate 110 and the initial docking is completed. At the same time, Adjust the second hydraulic column 208 in the clamping assembly 2, thereby driving the circular support block 202 inside the clamping column 206 to approach the right end of the mounting cylinder 111, so that the circular support block 202 is inserted into the inner wall of the right end of the mounting cylinder 111, and cooperates with the left end mounting column 109 to form a bidirectional positioning, thereby achieving stable installation of the material roll body 108; when replacing, first control the second hydraulic column 208 to retract so that the circular support block 202 is disengaged from the mounting cylinder 111, then control the first hydraulic column 103 to retract so that the lifting plate 104 is lowered, and after removing the old material roll, repeat the above steps to complete the replacement of the new material roll.
