Description

Technical Field

[0001] The invention relates to the technical field of paper roll transportation, and in particular to a face paper roll transportation device. Background Art

[0002] For large paper rolls, such as facing paper rolls, the traditional transportation method is to place the paper rolls upright so that the central axis of the paper roll is perpendicular to the carriage and the side of the paper roll is in contact with the carriage. This method is firmly fixed, but during transportation, the side of the paper roll and the carriage are prone to relative movement, which can easily damage the side of the facing paper that is in contact with the carriage, affecting subsequent gypsum board production.

[0003] In order to solve the above problems, the existing transportation method is to lay the paper roll flat so that the central axis of the paper roll is parallel to the carriage and perpendicular to the moving direction of the transport vehicle, and fix the two sides of the paper roll by fixing triangular pads on both sides of the paper roll, as shown in the attached figure. Figure 1 As shown, a paper roll is arranged between two triangular pads, and insertion holes are arranged at the central axis on both sides of the paper roll.

[0004] However, during transportation by the transport vehicle, the paper roll will still roll forward and backward due to inertia, and the triangular pads will easily exert force on the facing paper on the outer surface of the paper roll, causing damage to the facing paper on the outer surface of the paper roll. In particular, when the circumference of the outer surface of the paper roll is long, more facing paper will be damaged, resulting in greater transportation losses. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 2 and Figure 3 As shown, the present invention provides a face paper roll transport device, comprising:

[0034] Bottom plate 1, fixed on the carriage;

[0035] The placing platform 2 is used to place the paper roll and is arranged on the top of the bottom plate 1. When the paper roll is placed on the placing platform 2, the central axis of the paper roll is parallel to the forward direction of the carriage, and the placing platform 2 moves along the length direction of the bottom plate 1 under the action of external force;

[0036] A fixing frame 3 is used to limit the two sides of the paper roll. The number is set to two. The two fixing frames 3 are respectively arranged on the two sides of the paper roll, and the fixing frames 3 move along the length direction of the bottom plate 1 under the action of external force;

[0037] Among them, the placement platform 2 supports the paper roll, and the fixed frame 3 limits the two sides of the paper roll, so that the fixed frame 3, the paper roll and the placement platform 2 form a whole. When the paper roll is subjected to external force, the fixed frame 3, the paper roll and the placement platform 2 move forward and backward along the bottom plate 1 at the same time, so that the paper roll and the placement platform 2 are relatively stationary.

[0038] As shown in the attached figure Figure 1 As shown, a paper roll is arranged between two triangular pads, and there are insertion holes at the central axis on both sides of the paper roll. The existing transportation method is to lay the paper roll flat so that the central axis of the paper roll is parallel to the carriage and perpendicular to the moving direction of the transport vehicle, and fix the two sides of the paper roll by fixing triangular pads on both sides of the paper roll.

[0039] During transportation by the transport vehicle, the paper roll will still roll forward and backward due to inertia, and the triangular pads will easily exert force on the protective paper on the outer surface of the paper roll, causing damage to the protective paper on the outer surface of the paper roll. In particular, when the circumference of the outer surface of the paper roll is long, more protective paper will be damaged, resulting in greater transportation losses. Therefore, it is necessary to develop a protective paper roll transportation device with less transportation losses.

[0040] In this embodiment, the central axis of the face paper roll is parallel to the forward direction of the carriage, and is supported by the movable placement platform 2 and fixed by the movable fixing frame 3. When the paper roll is subjected to external force, the fixing frame 3, the paper roll and the placement platform 2 move forward and backward along the bottom plate 1 at the same time, so that the paper roll and the placement platform 2 are relatively stationary, and the fixing frame 3 drives the paper roll to move, so that the squeezing force of the fixing frame 3 on the paper roll is small, and the diameter of the paper roll at the center is small, thereby reducing damage to the paper roll during transportation and reducing transportation losses.

[0041] In actual use, 1. first place the paper roll on the placement platform 2 so that the central axis of the paper roll is parallel to the forward direction of the carriage;

[0042] 2. The two fixing frames 3 are clamped and fixed on both sides of the paper roll to limit and fix the paper roll;

[0043] 3. During the forward movement of the transport vehicle, when the vehicle accelerates or decelerates, the fixing frame 3, the paper roll and the placement platform 2 simultaneously move forward and backward along the bottom plate 1, so that the paper roll and the placement platform 2 are relatively stationary.

[0044] The device can keep the paper roll stationary relative to the placement platform 2 during transportation, thereby preventing the paper roll from being damaged due to relative movement between the paper roll and the placement platform 2.

[0045] As a preferred embodiment of the present embodiment, the structure for moving the placement platform 2 relative to the base plate 1 is introduced in detail below. A first groove 4 is provided at the top of the base plate 1, and a slide bar 5 arranged parallel to the forward direction of the carriage is fixedly connected inside the first groove 4. A moving block 6 is fixedly connected to the bottom of the placement platform 2. The moving block 6 is arranged on the outer surface of the slide bar 5, and the moving block 6 slides back and forth along the slide bar 5 under the action of external force. A first spring 7 is sleeved on the outer surface of the slide bar 5, and the two ends of the first spring 7 are fixedly connected to the moving block 6 and the inner wall of the first groove 4 respectively.

[0046] When the transport vehicle accelerates or decelerates, the placement platform 2 and the paper roll will have inertia and tend to move forward or backward. The device causes the slide bar 5 and the moving block 6 to slide relative to each other. Under the action of inertia, the moving block 6 moves along the slide bar 5, thereby causing the paper roll and the placement platform 2 to move synchronously, and preventing the paper roll from moving relative to the placement platform 2 at the top of the placement platform 2. At the same time, a first spring 7 is provided to increase a certain resistance and reduce the moving distance of the moving block 6.

[0047] The following is a detailed introduction to the structure of the fixed frame 3 moving relative to the bottom plate 1. The bottom plate 1 has second grooves 8 on both sides of the top, and the two second grooves 8 are respectively arranged on the front and rear sides of the first groove 4. The bottom of the fixed frame 3 is fixedly connected with a slider 9, and a telescopic rod 10 is fixedly connected between the slider 9 and the inner wall of the second groove 8. The outer surface of the telescopic rod 10 is sleeved with a second spring 11, and the two ends of the second spring 11 are respectively fixedly connected to the inner wall of the second groove 8 and the slider 9. The slider 9 is slidably connected to the second groove 8.

[0048] When the transport vehicle accelerates or decelerates, the fixed frame 3 and the paper roll will have inertia and tend to move forward or backward. The device slides the slider 9 relative to the second groove 8. Under the action of inertia, the slider 9 moves along the second groove 8, so that the fixed frame 3 drives the paper roll to move synchronously, and prevents the paper roll from moving relative to the fixed frame 3. At the same time, a second spring 11 is provided to increase a certain resistance and reduce the moving distance of the slider 9. At the same time, a telescopic rod 10 is provided. The joint action of the second spring 11 and the telescopic rod 10 has a buffering and shock-absorbing effect, reducing the moving distance of the fixed frame 3, the placement platform 2 and the paper roll.

[0049] If the top of the placement platform 2 is flat, the paper roll may roll left and right during transportation. To solve this problem, Figure 4 As shown, the top of the placement platform 2 is provided with a downwardly concave arc placement groove 12, the inner wall of the placement groove 12 is in contact with the outer surface of the paper roll, the paper roll can be stuck inside the placement groove 12, and will not roll left and right, so that the paper roll and the placement platform 2 are closer and difficult to move relative to each other, and a friction layer 13 is provided on the inner wall of the placement groove 12. By providing the friction layer 13, the friction between the paper roll and the friction layer 13 is increased, making it more difficult for the paper roll to move relative to the placement platform 2

[0050] A connecting plate 14 is fixedly connected between the fixing frame 3 and the placing platform 2, so that the fixing frame 3 and the placing platform 2 are a whole and will not move relative to each other, and the friction force between the paper roll and the friction layer 13 is greater than the sum of the elastic forces of the first spring 7 and the second spring 11. When the vehicle accelerates or decelerates during driving, since the friction force between the paper roll and the friction layer 13 is large and greater than the sum of the elastic forces of the first spring 7 and the second spring 11, the paper roll can be kept stationary relative to the placing platform 2, so that the slider 9 and the moving block 6 overcome the elastic forces of the first spring 7 and the second spring 11 and move.

[0051] Since the paper rolls have different types, in order to make the device suitable for paper rolls with different diameters, further, as Figure 4 As shown, a placement block 15 is detachably connected to the top of the placement platform 2, and the placement slot 12 is opened on the top of the placement block 15. The placement block 15 has multiple models, and the placement slots 12 on the placement blocks 15 of different models have different diameters, so as to place paper rolls of different diameters. The present application is provided with a detachable placement block 15, and the placement slot 12 is provided on the placement block 15. When transporting paper rolls of different diameters, it is only necessary to replace the placement blocks 15 of different models, without replacing the entire device, so that the device can adapt to paper rolls of different diameters.

[0052] The disassembly structure of the placement block 15 and the placement platform 2 is described below. Figure 4 and Figure 5 As shown, a slot 16 is provided on the top of the placement platform 2, and the placement block 15 is clamped inside the slot 16. Connecting plates 17 are fixedly connected on both sides of the placement block 15. Connecting slots 18 are provided on both sides of the top of the slot 16. The connecting plates 17 are clamped in the connecting slots 18, and the connecting plates 17 are fixedly connected to the placement platform 2 by bolts. The placement block 15 is fixedly clamped by providing the slot 16 and the connecting slot 18, so that the placement block 15 is stably connected to the placement platform 2.

[0053] Placing the roll of paper in the placement slot 12 or taking the roll of paper out of the placement slot 12 requires the roll of paper to be moved up and down in the vertical direction. Otherwise, the edges on both sides of the placement slot 12 may scratch the outer surface of the roll of paper, thereby increasing the transportation damage of the roll of paper. In order to solve this problem, Figure 5 As shown, notches 19 are provided on both sides of the top of the inner wall of the placement groove 12, and a roller 20 rotatably connected to the placement block 15 is provided at the notch 19, and the extension line of the inner wall of the friction layer 13 to both sides is tangent to the outer surface of the roller 20.

[0054] By providing the roller 20, and the extension lines of the inner wall of the friction layer 13 to both sides are tangent to the outer surface of the roller 20, the normal placement of the paper roll is not affected, and when placing or removing the paper roll, there is no need to move the paper roll up and down in the vertical direction, and the paper roll can be offset in the front-to-back direction during the placement or removal process. When the paper roll contacts the roller 20, the roller 20 rotates without damaging the paper roll, and the placement and removal of the paper roll are facilitated.

[0055] The structure of the fixing frame 3 is described in detail below. The fixing frame 3 includes a vertical plate 21 and a cross bar 22 arranged on the top of the vertical plate 21. The end of the cross bar 22 close to the placement platform 2 is connected to a vertically arranged limit plate 23. A fixed shaft 24 is fixedly connected to the side of the limit plate 23 close to the placement platform 2. The fixed shaft 24 is plugged into the socket on the paper roll. By providing the fixed shaft 24 and inserting the fixed shaft 24 into the socket of the paper roll, the fixing effect of the paper roll can be improved and the paper roll can be limited. At the same time, the limit plate 23 is provided to limit the front and rear directions of the paper roll to prevent the paper roll from moving forward and backward relative to the fixing frame 3 during the movement process.

[0056] In order to make the fixing frame 3 just stuck on the front and rear sides of the paper roll, and make the device suitable for paper rolls of different widths, such as Figure 3 As shown, a sleeve 25 is fixedly connected to the top of the vertical plate 21, an outer surface of the cross bar 22 is provided with an external thread, and an inner wall of the sleeve 25 is provided with an internal thread, so that the cross bar 22 is threadedly connected with the sleeve 25, and the distance between the limit plate 23 and the paper roll is adjusted by rotating the cross bar 22;

[0057] The limiting plate 23 is rotatably connected to the cross bar 22 via a bearing.

[0058] When in use, the distance between the two cross bars 22 is the largest. First, place the paper roll on the placement platform 2, and then rotate the cross bars 22 to move both cross bars 22 toward the paper roll until the fixed shaft 24 is inserted into the insertion hole and the limit plate 23 is close to the side of the paper roll.

The protection scope of the present application is defined by the claims.
