Description

Technical Field

[0001] The utility model belongs to the technical field of paper roll clamping, in particular to a paper roll clamping device. Background Art

[0002] At present, the finished products produced by paper mills are mostly large paper rolls. When clamping the paper rolls, most of them use clamps installed on forklifts to clamp the paper rolls and then transport them.

[0003] However, the existing clamps use squeezing friction to clamp the paper roll. Due to the heavy weight of the paper roll, vibration is inevitable when the forklift is transported, which causes the clamped paper roll to have a large downward force. The contact surface between the paper roll and the clamp will be pulled and damaged, affecting the integrity of the paper roll structure and causing damage to the paper roll.

[0004] Therefore, a paper roll clamping device is proposed. Utility Model Content

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model provides a paper roll clamping device, such as Figure 1-4 As shown, it includes a fixed plate 1, a clamping seat 21 in the clamping assembly 2 is fixedly connected to the outer wall of one side of the fixed plate 1 by bolts, a first rotating cylinder 22 is fixedly connected to the first clamping plate 23 through an output end of one side of the first rotating cylinder 22, a second rotating cylinder 24 is fixedly connected to the second clamping plate 25 through an output end of one side of the first clamping plate 23, a first motor 31 in the lifting assembly 3 is fixedly connected to the central position of the top of the fixed plate 1 by bolts, the first motor 31 is fixedly connected to the first ball screw 32 through an output end of one side of the first motor 31, a nut seat on the first ball screw 32 is fixedly connected to a lifting platform 33 through a nut, and the lifting platform 33 A second motor 34 is fixedly connected to the central position of the outer wall on one side by bolts, and a second ball screw 35 is fixedly connected to the second motor 34 through an output end on one side thereof. A third ball screw 36 is fixedly connected to one end of the second ball screw 35 by a key, and the screw threads in the second ball screw 35 and the third ball screw 36 have opposite rotation directions. The nut seat on the second ball screw 35 is fixedly connected to the first support plate 37 through a nut, and the nut seat on the third ball screw 36 is fixedly connected to the second support plate 38 through a nut. A reinforcing inclined plate 39 is welded on the inner walls of one side of the first support plate 37 and the second support plate 38, and a mounting platform 4 is welded on the outer wall on the other side of the fixed plate 1. A mounting hole that can be connected to the forklift lifting structure is opened on the outer wall of the mounting platform 4 on the side away from the fixed plate 1.

[0022] It should be noted that since the existing clamps use squeezing friction to clamp the paper roll, due to the heavy weight of the paper roll, it is inevitable that vibrations will occur during transportation by forklift, which will cause the clamped paper roll to have a large downward force, and the contact surface between the paper roll and the clamp will be damaged by pulling, affecting the integrity of the paper roll structure and causing damage to the paper roll. In this embodiment, the lifting component 3 can support the vertically clamped paper roll in the vertical direction, ensure the stability of the paper roll after it is clamped and transported, provide additional support for the paper roll after it is clamped, and avoid the problem of the outer wall of the paper roll being damaged by pulling due to vibrations generated by transportation at the clamping point of the paper roll and the clamping component 2.

[0023] Specifically, in this embodiment, this scheme mainly includes a clamping assembly 2 and a lifting assembly 3. When in use, the mounting platform 4 is fixedly installed on the lifting end of the forklift. When clamping the paper roll, the forklift moves the clamping assembly 2 to the outside of the paper roll drum. At this time, the first rotating cylinder 22 is controlled to work. The first rotating cylinder 22 drives the first clamping plate 23 to rotate around the clamping seat 21 through the output end on one side thereof. The second rotating cylinder 24 drives the second clamping plate 25 to rotate around the clamping seat 21 through the output end on one side thereof. The first clamping plate 23 and the second clamping plate 25 are in contact and squeezed with the outer wall of the paper roll to achieve clamping of the paper roll. The forklift lifts the clamping assembly 2 upward, and the bottom of the paper roll leaves the ground. At this time, the lifting assembly 3 is controlled to support the paper roll. The first motor 31 drives the first ball screw 32 to rotate through the output end on one side thereof, and the lifting platform 33 is lifted and lowered on the fixed plate 1, controlling the first support plate 37 and the second support plate 38 to be lifted and lowered to the bottom of the paper roll. At this time, the second motor 34 drives the second ball screw 35 and the third ball screw 36 to rotate through the output end on one side thereof. Since the screw threads on the second ball screw 35 and the third ball screw 36 have opposite rotation directions, the first support plate 37 and the second support plate 38 move toward each other, and the first support plate 37 and the second support plate 38 move to the bottom of the paper roll, and control the lifting platform 33 to move upward again, so that the top of the first support plate 37 and the second support plate 38 are in contact with the bottom of the paper roll, so as to support the paper roll and ensure the stability of the paper roll during transportation after clamping.

[0024] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the cross sections of the first clamping plate 23 and the second clamping plate 25 are both arc-shaped structures.

[0025] In this embodiment, the first clamping plate 23 and the second clamping plate 25 can be closely attached to the outer side wall of the paper roll due to the arc-shaped structure, thereby achieving stable clamping of the paper roll.

[0026] In a further preferred embodiment of the present invention, Figure 1 , Figure 3 and Figure 4As shown, the fixed plate 1 and the lifting platform 33 are slidably connected via a slider and a slide groove, and the first support plate 37 and the second support plate 38 are slidably connected to the lifting platform 33 via a slider and a slide groove.

[0027] In this embodiment, the stability of the lifting platform 33 in lifting and lowering on the fixed plate 1 and the stability of the first support plate 37 and the second support plate 38 in moving on the lifting platform 33 can be ensured by the sliding connection.

[0028] In a further preferred embodiment of the present invention, Figure 1 and Figure 4 As shown, the cross-sections of the first support plate 37 and the second support plate 38 are both L-shaped structures, and the first support plate 37 and the second support plate 38 are combined with the reinforcing inclined plate 39 to form a triangular frame structure.

[0029] In this embodiment, the triangular frame structure can ensure the structural strength of the first support plate 37, the second support plate 38 and the reinforcing inclined plate 39, thereby better supporting the paper roll.
