Description

Technical Field

[0001] This invention relates to the field of roll material transport trolley technology, and more particularly to a more stable composite film roll material transport trolley. Background Technology

[0002] Packaging films are typically made from two or more of the following materials: PET, VMPET, pearlescent film, aluminum foil, heat-sealable OPP, heat-sealable VMOPP, matte OPP, heat-sealable pearlescent film, and PE. The composite film rolls are usually wound on a spool. When handling the rolls, the inner wall of the spool is pushed upwards with the palm of the hand to lift the roll horizontally and place it on a hydraulically adjustable trolley for transport. After reaching the corresponding processing equipment, the lever of the hydraulic pump on the trolley is operated to lift the trolley's platform. The roll, lying horizontally on the platform, is lifted together with the platform, aligning with the height of the equipment's rollers for easy transfer onto the rollers. However, during the lifting and lowering of the platform, the trolley shakes due to the lever operation, causing the roll lying horizontally on the platform to easily roll towards the edge and fall off, damaging the outer layer of the roll and increasing the loss of both raw materials and finished products of the composite film. Therefore, designing a more stable composite film roll transport trolley that can reduce the rolling of the roll on the trolley platform and prevent the roll from falling has become an urgent technical problem to be solved. Summary of the Invention

[0003] To solve the above problems, this utility model provides a more stable composite film roll transport trolley.

[0004] The technical solution of this utility model is a more stable composite film roll transport trolley, including a hydraulic lifting trolley. The hydraulic lifting trolley includes a vertically lifting platform, a foldable support frame connected to the bottom of the platform, and an oil pump that drives the support frame to unfold upward. The platform is provided with a slide groove and a pair of support blocks. The bottom of the support blocks is provided with a slider. The support blocks are provided with a connecting plate on the opposite side and an arc-shaped surface on the opposite side. The slider is slidably connected in the slide groove. The slide groove is set along the length direction of the platform. The connecting plate is threadedly connected to a vertical drive screw. The bottom end of the drive screw extends into the slide groove and is connected to a positioning block. The positioning block abuts against the bottom of the slide groove.

[0005] With the above structure, the roll material is placed horizontally on the table between two support blocks, with the circumference of the roll material aligned with the arc-shaped surface of the support block. The drive screw, threaded onto the connecting plate, is rotated, causing it to move vertically upwards. This moves the positioning block connected to its bottom, separating it from the bottom of the sliding groove and eliminating friction. The support blocks are then pushed, causing the slider at the bottom of the support blocks to move along the sliding groove. The support blocks approach the roll material from both sides until the arc-shaped surface lightly touches the side of the roll material. Finally, the drive screw is reversed to position the roll material. The block descends and re-clamps against the bottom of the chute, generating friction to prevent the support block from continuing to move along the chute. This keeps the support block in the direction where the roll might roll. By operating the oil pump's pedal and adjusting the pump pressure, the support frame is driven upwards. As the support frame pushes the platform upwards, it prevents the roll from rolling. This achieves the goal of having the support block, after the roll is laid horizontally on the platform, move along the chute to adhere to the circumference of the roll, preventing it from rolling. This eliminates the risk of the roll rolling off the platform due to the trolley's movement and avoids damage from falling rolls.

[0006] As a further improvement of this utility model, the curved surface is covered with a protective pad.

[0007] With the above structure, the curved surface is covered with a protective pad. When the curved surface is attached to the roll material, the protective pad directly contacts the roll material. When the trolley shakes, the roll material tends to roll, squeezing the protective pad. The flexible deformation of the protective pad provides cushioning and protection, preventing scratches from being left on the surface of the roll material.

[0008] As a further improvement of this utility model, the number of sliding grooves is not less than two, and the sliding grooves are arranged at equal intervals along the width direction of the support block. The number of sliders, drive screws and positioning blocks are all corresponding to the number of sliding grooves.

[0009] With the above structure, there are no fewer than two sliding grooves, which are arranged at equal intervals along the width of the support block, making the movement of the support block along the sliding groove more stable.

[0010] As a further improvement of this utility model, the connecting plate is provided with a vertical internal threaded hole, the driving screw passes through the internal threaded hole and is threadedly connected to the connecting plate, the top of the driving screw is connected to a driving knob, and the side of the driving knob is provided with an anti-slip groove.

[0011] With the above structure, the drive screw passes through the internal threaded hole and is threadedly connected to the connecting plate. Rotating the drive screw and the internal threaded hole allows the drive screw to move vertically along the internal threaded hole. A drive knob is connected to the top of the drive screw, making it easy to grasp the drive knob to apply force to rotate the drive screw, avoiding scratches to the operator's palm from the threads of the drive screw. The side of the drive knob is provided with anti-slip grooves to increase the friction between the drive knob and the palm, preventing slippage when rotating the drive screw.

[0012] As a further improvement of this utility model, the bottom surface of the positioning block is provided with an anti-slip pad, and the bottom surface of the anti-slip pad is provided with anti-slip texture.

[0013] With the above structure, the bottom surface of the positioning block is provided with an anti-slip pad, and the bottom surface of the anti-slip pad is provided with anti-slip texture. When the positioning block is pressed against the bottom of the slide groove, the anti-slip pad further increases the friction between the two, which more effectively restricts the support block from sliding along the slide groove.

Detailed Implementation

[0018] like Figures 1-3 The diagram shows a more stable composite film roll transport trolley, including a hydraulic lifting trolley 1. The hydraulic lifting trolley 1 includes a vertically lifting platform 2, a foldable support frame 3 connected to the bottom of the platform 2, and an oil pump 4 that drives the support frame 3 to unfold upwards. The platform 2 is provided with a slide groove 5 and a pair of support blocks 6. The bottom of the support blocks 6 is provided with a slider 7. The support blocks 6 are provided with a connecting plate 8 on the opposite side and an arc-shaped surface 9 on the opposite side. The slider 7 is slidably connected in the slide groove 5. The slide groove 5 is set along the length direction of the platform 2. The connecting plate 8 is threadedly connected to a vertical drive screw 10. The bottom end of the drive screw 10 extends into the slide groove 5 and is connected to a positioning block 11. The positioning block 11 abuts against the bottom of the slide groove 5.

[0019] By placing the roll material horizontally on the table 2 between two support blocks 6, with the circumference of the roll material aligned with the arc-shaped surface 9 of the support block 6, and rotating the drive screw 10 threaded onto the connecting plate 8, the drive screw 10 moves vertically upward, causing the positioning block 11 connected to the bottom to separate from the bottom of the groove 5 that was originally pressed against it, eliminating the friction between them. Then, the support blocks 6 are pushed, causing the slider 7 at the bottom of the support blocks 6 to move along the groove 5. The support blocks 6 move closer to the roll material from both sides until the arc-shaped surface 9 lightly touches the side of the roll material. After that, the drive screw 10 is reversed, and the positioning block... 11. The lowering mechanism re-engages the support block 6 with the bottom of the chute 5, generating friction to prevent the support block 6 from continuing to move along the chute 5. The support block 6 is kept in the direction in which the roll material may roll. By operating the pedal of the oil pump 4 and adjusting the pump pressure of the oil pump 4 to drive the support frame 3 to unfold upward, the support frame 3 prevents the roll material from rolling as it pushes the table 2 upward. This achieves the goal of the support block 6 moving along the chute 5 to adhere to the circumference of the roll material after it is laid horizontally on the table 2, preventing the roll material from rolling and eliminating the risk of the roll material rolling off the table 2 due to the swaying of the trolley, thus avoiding damage to the roll material from falling.

[0020] The curved surface 9 is covered with a protective pad 12.

[0021] The curved surface 9 is covered with a protective pad 12. When the curved surface 9 is attached to the roll material, the protective pad 12 directly contacts the roll material. When the trolley shakes, the roll material tends to roll, squeezing the protective pad 12. The flexible deformation of the protective pad 12 is used for buffering and protection, avoiding scratches on the surface of the roll material.

[0022] There are no fewer than two slide grooves 5. The slide grooves 5 are arranged at equal intervals along the width direction of the support block 6. The number of sliders 7, drive screws 10 and positioning blocks 11 are all corresponding to the number of slide grooves 5.

[0023] With at least two slide grooves 5, and arranged at equal intervals along the width of the support block 6, the support block 6 can be moved more stably along the slide grooves 5.

[0024] The connecting plate 8 is provided with a vertical internal threaded hole 13. The drive screw 10 passes through the internal threaded hole 13 and is threadedly connected to the connecting plate 8. The top of the drive screw 10 is connected to a drive knob 14. The side of the drive knob 14 is provided with an anti-slip groove 15.

[0025] The drive screw 10 passes through the internal threaded hole 13 and is threadedly connected to the connecting plate 8. Rotating the drive screw 10 and the internal threaded hole 13 allows the drive screw 10 to move vertically along the internal threaded hole 13. A drive knob 14 is connected to the top of the drive screw 10, which is easy to grasp and apply force to rotate the drive screw 10, avoiding the operator's palm from being scratched by the threads of the drive screw 10. The side of the drive knob 14 is provided with an anti-slip groove 15 to increase the friction between the drive knob 14 and the palm, preventing slippage when rotating the drive screw 10.

[0026] The bottom surface of the positioning block 11 is provided with an anti-slip pad 16, and the bottom surface of the anti-slip pad 16 is provided with anti-slip texture 17.

[0027] The bottom surface of the positioning block 11 is provided with an anti-slip pad 16, and the bottom surface of the anti-slip pad 16 is provided with anti-slip texture 17. When the positioning block 11 is pressed against the bottom of the groove 5, the anti-slip pad 16 further increases the friction between the two, and more effectively restricts the support block 6 from sliding along the groove 5.
