After that, it rolls to the rear end of the frame, and then the electronic scale 6 is extended to lift the rolled material off the frame, so that the weight of the rolled material can be weighed. This application integrates the three actions of unloading, packaging and weighing into a small cart, eliminating the need for frequent movement of the rolled material, which can effectively save manpower and resources and improve efficiency.

[0031] Example 2

[0032] Please see Figures 1-3 Based on Embodiment 1, the frame includes a top plate 1, a support rod 2, and a bottom plate 3. The top plate 1 and the bottom plate 3 are fixedly connected by the support rod 2 and are arranged in parallel.

[0034] The top plate 1 is provided with a lifting groove 17;

[0035] Two sets of guide rollers 29 are symmetrically arranged inside the lifting groove 17;

[0036] A second cylinder 9 is fixedly connected to the base plate 3, and a support plate 8 is fixedly connected to the second cylinder 9. An electronic scale 6 is provided on the support plate 8, and the electronic scale 6 and the support plate 8 can extend the lifting groove 17 from between the two sets of guide rollers 29.

[0037] The bottom plate 3 is rotatably connected to a support wheel 4;

[0038] A third cylinder 10 is provided on the lower side of the base plate 3. One end of the third cylinder 10 is fixedly connected to the base plate 3, and the other end of the third cylinder 10 is fixedly connected to the bottom surface.

[0039] A retraction activation button 11 is provided on the front side of the top plate 1. The retraction activation button 11 is used to control the third cylinder 10 to shorten. A forward activation button 14 is provided on the rear side of the top plate 1. The forward activation button 14 is used to control the third cylinder 10 to extend.

[0040] The third cylinder 10 automatically stops extending when it reaches its limit position, and automatically stops shortening when it reaches its limit position.

[0041] A first cylinder lifting button 12 is provided on the front side of the top plate 1. The first cylinder lifting button 12 is used to control the extension and retraction of the first cylinder 7.

[0042] A second cylinder lifting button 13 is provided on the rear side of the top plate 1. The second cylinder lifting button 13 is used to control the extension and retraction of the second cylinder 9.

[0043] The top plate 1 has a slot at its front end, the guide plate 5 is rotatably connected to the slot, and a safety support rod 16 is provided at the edge of the slot.

[0044] The working principle and beneficial effects of the above scheme are as follows:

[0045] The first cylinder 7, the second cylinder 9, and the third cylinder 10 mentioned above are controlled by the reverse start button 11, the first cylinder lifting button 12, the second cylinder lifting button 13, and the forward start button 14, respectively. This is prior art and is not within the scope of protection of this application. For reference, see Chinese Patent Publication No. CN222479089U Cylinder Control Circuit and Cylinder, CN222686988U Cylinder Control System, and CN222542793U A PLC-based Adjustable Stroke Control Circuit for Cylinders.

[0046] The frame is designed as a frame structure consisting of a top plate 1, a support rod 2, and a bottom plate 3, which effectively reduces the weight of the frame.

[0047] The first cylinder lifting button 12 is located at the front end of the top plate 1, close to the rolled material, which makes it convenient for personnel to operate when unloading the rolled material;

[0048] The tilting angle of the guide plate 5 is adjusted by the extension of the first cylinder 7, so that the angle of the guide plate 5 can adapt to rolls with different winding layers.

[0049] After the rolled material is packaged and moved above the lifting groove 17, the rolled material only contacts the edge of the lifting groove 17. The second cylinder 9 is activated and extends, causing the electronic scale 6 and the support plate 8 to extend out of the lifting groove 17. At this time, the rolled material falls onto the electronic scale 6, and the weighing is completed.

[0050] After weighing is completed, the second cylinder 9 shortens, and the rolled object falls onto the guide roller 29. At this time, pulling the rolled object will allow it to fall off the trolley. The guide roller and the rolled object roll and rub against each other, greatly reducing the friction. When the center of gravity of the rolled object extends beyond the outside of the trolley, the rolled object falls under the action of gravity, saving time and effort.

[0051] The first cylinder lifting button 12 is located at the rear end of the top plate 1, near the weighing position of the rolled material, for easy operation by personnel;

[0052] Once the roll is disassembled, the trolley needs to be driven away to facilitate the rewinding machine to rewind it. At this time, the operator is close to the rewinding machine and can easily operate by pressing the back button 11.

[0053] After the roll is weighed, the operator is located at the rear of the trolley. The trolley needs to move forward to approach the winding machine to wait for the next unloading of the roll. The forward start button 14 is located on the rear side of the top plate 1 for easy operation.

[0054] The car's forward and backward movement is powered by the third cylinder 10, while the support wheel 4 serves to bear gravity and reduce friction.

[0055] Example 3

[0056] Please see Figure 4 Based on Embodiment 1, an anti-roll-off component is provided at the rear end of the top plate 1.

[0057] The anti-roll-off component includes an anti-detachment plate 18, which is fixedly connected to the rear end of the top plate 1. The anti-detachment plate 18 is arc-shaped. A shock-absorbing plate 19 is provided on the inner side of the anti-detachment plate 18. The upper surface of the lower end of the shock-absorbing plate 19 is flush with the upper surface of the top plate 1. A first connecting rod 20 is fixedly connected to the lower end of the shock-absorbing plate 19. The first connecting rod 20 is slidably inserted into a first sliding groove 21 provided in the anti-detachment plate 18. A first sliding plate 22 is fixedly connected to one end of the first connecting rod 20 located in the first sliding groove 21. The first sliding plate 22 is slidably connected in the first sliding groove 21. A first spring 23 is provided between the first sliding plate 22 and the first sliding groove 21.

[0058] A second connecting rod 24 is symmetrically arranged between the anti-detachment plate 18 and the shock-absorbing plate 19. One end of the second connecting rod 24 is rotatably connected to the shock-absorbing plate 19, and the other end of the second connecting rod 24 is slidably connected to the second sliding groove 25 provided in the anti-detachment plate 18. A second sliding plate 27 is slidably connected in the second sliding groove 25. A third connecting rod 26 is fixedly connected to the second sliding plate 27. The second connecting rod 24 and the third connecting rod 26 are rotatably connected. A second spring 28 is provided between the end of the second sliding plate 27 and the end of the second sliding groove 25.

[0059] The working principle and beneficial effects of the above scheme are as follows:

[0060] When the rolled material is rolled to the lifting groove 17, in order to prevent the rolled material from rolling off the top plate 1, the rolled material is blocked by the anti-roll-off component. When the rolled material comes into contact with the anti-roll-off component, in order to prevent the impact between the anti-roll-off component and the rolled material from causing damage to the rolled material, the shock-absorbing plate 19 is set to buffer.

[0061] When the rolled object comes into contact with the anti-roll-off component, the rolled object moves along the damping plate 19. Under the action of the inertia of the rolled object, it squeezes the damping plate 19. Due to the influence of the arc-shaped structure of the damping plate 19, the damping plate 19 moves downward as a whole under the limiting action of the first connecting rod 20, squeezing the first spring 23. The first spring 23 absorbs a certain impact force of the rolled object. As the relative position of the anti-slip plate 18 and the damping plate 19 changes, the second spring 28 at the lower end is squeezed by the second connecting rod 24, the third connecting rod 26 and the second sliding plate 27 at the upper end, and the second spring 28 at the upper end is stretched by the second connecting rod 24, the third connecting rod 26 and the second sliding plate 27 at the upper end, so as to perform secondary buffering, effectively protect the rolled object and prevent the rolled object from falling.

[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
