Description

Technical Field

[0001] This application relates to the technical field of papermaking equipment, and particularly to a paper roll rewind device. Background Art

[0002] After the paper roll is unloaded from the winder after the paper machine, coater or supercalender, it needs to be further rewound. However, the last section of the paper web of the paper roll cannot be used for the production of the finished roll. Therefore, before rewinding, it is necessary to use a rewind device for rewind processing. The principle of paper tail rewind is that the paper roll rotates to eject part of the paper tail, and the ejected paper tail is cut and rewound.

[0003] However, the existing rewind device is not reasonably designed, resulting in a relatively complex installation and connection process between the paper roll and the rewind device, thus increasing the operation difficulty and reducing the rewind efficiency of the paper roll. Summary of the Utility Model

[0015] In one embodiment, it further includes a driving component. The driving component is arranged on the frame, and the driving component acts on the power component to drive the power component to move on the frame.

[0016] In one embodiment, it further includes a collision prevention frame;

[0017] The collision prevention frame is arranged on the frame. When the first connecting piece and the second connecting piece on the frame are completely connected, the collision prevention frame surrounds the top surface and / or at least part of the side surface of the power component.

[0018] In one embodiment, it further includes a positioning frame assembly;

[0019] The positioning frame assembly includes at least two positioning plates.

[0037] Existing products of the paper roll rewind device have problems such as increased operation difficulty and low efficiency caused by the complex process of installing the paper roll.

[0038] Figure 1 It is a schematic structural diagram of one of the embodiments provided by the present application.

[0039] Figure 2 It is a schematic structural diagram of the second embodiment provided by the present application.

[0040] See Figure 1 , in the paper roll rewind device of the present application, an active connection between the power member and the frame is adopted, and the power member can drive the first connecting member to quickly connect or separate from the second connecting member of the reel assembly on the frame, reducing the complexity of the installation connection of the paper roll on the rewind device and improving the rewind efficiency of the paper roll.

[0041] The present application provides a paper roll rewind device, which includes a frame 10, a drive structure 20, and a reel assembly 40.

[0042] The drive structure 20 includes a power member 21, a first connecting member 22, and a second connecting member 23. The power member 21 is movably arranged on the frame 10, the first connecting member 22 is arranged on the power member 21, and the second connecting member 23 is arranged on the reel assembly 40.

[0043] Before use, the paper roll 90 has been wound at the paper outlet end of the paper machine on the reel assembly 40.

[0044] During use, the reel assembly 40 and the paper roll 90 are hoisted onto the frame 10 together by means of a crane or the like, and the reel assembly 40 is rotatably arranged on the frame 10. The power member 21 moves relative to the frame 10 to drive the second connecting member 23 to approach and connect to the first connecting member 22. At this time, the power member 21 is fixed, and then the power member 21 is started to drive the reel assembly 40 to rotate.

[0045] The frame 10 can be a rack formed by splicing multiple crossbeams and having a load-bearing capacity. This is prior art and will not be elaborated here.

[0046] The power member 21 can be a power device such as a motor. The first connecting member 22 is usually arranged at the output end of the power member 21.

[0047] The reel assembly 40 can rotate after being set on the frame 10. From this, it can be known that if the reel assembly 40 only includes the main shaft, the main shaft can be directly rotatably set on the frame 10. However, generally, to reduce the friction between the main shaft and the frame 10, bearings are usually provided at both ends of the main shaft, and the main shaft is rotatably connected to the frame 10 through the bearings. In this embodiment, the second connecting member 23 is on one end of the main shaft.

[0048] In this way, a positioning groove for bearing positioning is provided on the frame 10. After the crane lifts the main shaft, the bearing can be loaded into the positioning groove by aligning it with the positioning groove from top to bottom.

[0049] In one embodiment, the first connecting member 22 is a first tooth part, and the second connecting member 23 is a second tooth part; the first tooth part meshes with the second tooth part to realize the connection between the power member 21 and the reel assembly 40.

[0050] In this embodiment, the power transmission from the power member 21 to the reel assembly 40 is realized by the meshing of teeth, and the meshing method has the characteristics of precise and reliable transmission control.

[0051] In one embodiment, the first tooth part includes an internal gear ring provided at the end of the reel assembly 40, and the first tooth part includes an inserted tooth provided on the power member 21.

[0052] A groove is provided at one end of the main shaft of the reel assembly 40, and internal teeth are designed on the circumferential side wall of the groove, thus forming an internal gear ring; a gear is provided at the output end of the power member 21, which is the above-mentioned inserted tooth.

[0053] In the initial state, see Figure 2 , the power member 21 is set on the frame 10 and can move on the frame 10.

[0054] Before use, the paper reel 90 has been wound at the paper outlet end of the paper machine by the reel assembly 40.

[0055] When in use, see Figure 1 , the reel assembly 40 and the paper reel 90 are hoisted onto the frame 10 together by means of a crane or the like, and the reel assembly 40 is rotatably set on the frame 10. After the reel assembly 40 is set on the frame 10, at this time, the axis of the internal gear ring of the reel assembly 40 is parallel to the axis of the inserted tooth. Importantly, the projection of the inserted tooth in the axial direction is located in the internal gear ring, and the internal gear ring and the inserted tooth are arranged facing each other; the power member 21 is moved closer to the internal gear ring, and finally the inserted tooth is inserted into the internal gear ring. It can be known that when the inserted tooth is approaching and about to enter the internal gear ring, the inserted tooth can be rotated so that the teeth of the inserted tooth are staggered with the teeth of the internal gear ring, and finally the inserted tooth continues to move into the internal gear ring, and finally the inserted tooth meshes with the internal gear ring.

[0056] Next, fix the power component 21, and then start the power component 21. The power component 21 drives the main shaft to rotate through the gear shaper. It should be noted that the main shaft rotates in the opposite direction to the winding direction before the paper roll 90. The paper tail on the paper roll 90 drops off. When the length of the dropped paper section reaches the specified length, the dropped part is cut off to complete the rewind.

[0057] Furthermore, after the rewind is completed, the power component 21 retracts along the original path and moves away from the second connecting component 23. After the first connecting component 22 is separated from the second connecting component 23, the reel assembly 40 together with the completed rewind paper roll 90 is transferred to the rewinding process again by the crane.

[0058] In other cases, the internal gear ring can be replaced with a conventional gear. In this way, the gear shaper on the power component 21 meshes with the gear on the main shaft outside the main shaft. Additionally, when the internal gear ring is a conventional gear, the power component 21 can also be selected to approach from the radial direction of the main shaft and finally make the gear shaper mesh with the gear on the main shaft.

[0059] Alternatively, the first connecting component 22 can be a first convex part, and the second connecting component 23 is a first concave part. For example, the first convex part is a hexagonal prism, and correspondingly, the first concave part is a hexagonal counterbore. The hexagonal prism is inserted into the hexagonal counterbore to complete the connection between the power component 21 and the reel assembly 40.

[0060] In one embodiment, the paper roll rewind device further includes at least two parallel slide rail assemblies 30.

[0061] The slide rail assembly 30 includes a slider 31 and a slide rail 32. The slide rail 32 is arranged on the frame 10, and the slider 31 is arranged at the bottom of the power component 21. The slider 31 is slidably arranged on the slide rail 32.

[0062] Based on the above, taking two slide rail assemblies 30 as an example, the two slide rails 32 are arranged in parallel on both sides of the bottom of the power component 21. In this way, the slide rail 32 is arranged on the frame 10 along the axial direction of the main shaft. One slide rail assembly 30 includes at least one slider 31. The slider 31 is arranged at the bottom of the power component 21 and is slidably mounted on the slide rail 32. The two slide rails 32 and multiple sliders 31 are simultaneously arranged on one slide rail 32, which increases the support points at the bottom of the power component 21 and is beneficial to improving the sliding stability of the power component 21.

[0063] In one embodiment, it further includes an action base plate 80.

[0064] The action base plate 80 is arranged at the bottom of the power component 21. The slider 31 is arranged at the bottom of the action base plate 80, and the power component 21 is arranged at the top of the action base plate 80.

[0065] It can be understood that the action base plate 80 is preferably a square plate, which provides a sufficient installation platform for the power component 21 and ensures the stable installation of the power component 21.

[0066] In one embodiment, it further includes a driving component 50. The driving component 50 is arranged on the frame 10, and the driving component 50 acts on the power component 21 to drive the power component 21 to move on the frame 10.

[0067] Based on the foregoing, the power component 21 can be selected as a cylinder, a hydraulic cylinder or a linear motor. In this embodiment, the power component 21 can be arranged at the bottom of the action base plate 80 and between two slide rails 32, and the telescopic end of the driving component 50 is connected to the action base plate 80. In this way, the layout of each component on the frame 10 is more compact.

[0068] During use, the driving component 50 expands and contracts to drive the power component 21 to approach or move away from the second connecting component 23. During this process, the second connecting component 23 realizes the connection or separation with the first connecting component 22.

[0069] Specifically, when the driving component 50 expands and contracts to the maximum extension stroke, the first connecting component 22 just contacts the second connecting component 23. In this way, there is no need to additionally control the extension amount of the driving component 50 to ensure the connection between the first connecting component 22 and the second connecting component 23.

[0070] In one embodiment, referring to Figure 1 it further includes a collision prevention frame 60.

[0071] The collision prevention frame 60 is arranged on the frame 10. When the power component 21 completes the connection between the first connecting component 22 and the second connecting component 23 on the frame 10, the collision prevention frame 60 surrounds the top surface and / or at least part of the side surfaces of the power component 21.

[0072] The collision prevention frame 60 can be selected as multiple partition nets. It can be known that except for the two side surfaces perpendicular to the movement direction of the power component 21 where the partition nets do not need to be set, the other side surfaces and / or the top surface of the power component 21 are provided with partition nets. When the crane hoists the reel assembly 40 onto the frame 10, the partition nets effectively prevent the collision between the reel assembly 40 and the power component 21. Otherwise, the collision prevention frame 60 can be a collision prevention railing.

[0073] In one embodiment, referring to Figure 1 and Figure 2 it further includes a positioning frame assembly 70.

[0074] The positioning frame assembly 70 includes at least two positioning plates 71. Taking the mating position where the first connecting component 22 and the second connecting component 23 on the frame 10 complete the connection as the mating base point, one positioning plate 71 is arranged on each side of the second connecting component 23, and the positioning plates 71 on both sides of the second connecting component 23 are symmetric about the mating base point.

[0075] It should be noted that the matching position of the second connecting member 23 and the first connecting member 22 is the matching base point, and a positioning plate 71 is arranged on each side of the matching base point, and the positioning plates 71 on both sides are symmetrically arranged about the connection point. In other words, the two positioning plates 71 are arranged on the left and right sides of the positioning groove of the frame 10. Therefore, it can be understood that when the hoist lifts the reel assembly 40 from top to bottom on the frame 10, the two positioning plates 71 can provide a reference for the descent of the reel assembly 40, which is more convenient for the alignment and installation of the bearing on the main shaft and the positioning groove.

[0076] In one embodiment, the positioning frame assembly 70 further includes at least one top plate 72 .

[0077] The top plate 72 is disposed on the top of the positioning plate 71 on both sides of a matching base point.

[0078] Alternatively, the positioning frame assembly 70 further includes at least one top plate 72 .

[0079] The top plate 72 is disposed on the top of the positioning plate 71 on both sides of a matching base point.

[0080] The top surface of the top plate 72 is inclined toward the middle of the reel assembly 40 .

[0081] First, the top plate 72 can be horizontally set on the top of the positioning plate 71. The setting of the top plate 72 can use the midpoint of its part between the two positioning plates 71 as a reference to better visually capture the midpoint of the two positioning plates 71. This captured midpoint is located above the positioning groove. The reel assembly 40 is installed downward from this position, which can more accurately align the bearings on the main shaft and quickly install them in the positioning groove.

[0082] Secondly, on the basis of the first one, the top plate 72 of the first one is tilted toward the middle of the reel assembly 40. It can also be understood that the top plate 72 is tilted toward the middle of the two positioning grooves to form a low inside and high outside setting. The significance of the tilted setting of the top plate 72 is to prevent the reel assembly 40 from colliding with the top plate 72 when it is hoisted downward. The inclined surface of the top plate 72 can avoid a head-on collision and reduce the degree of damage to both parties of the collision.

[0083] In addition, the positioning plate 71 of the present embodiment adopts an L-shaped structure, and the top end of the L-shaped positioning plate 71 extends upward to the side of the positioning groove away from the connection point between the second connecting member 23 and the first connecting member 22. The significance of such a setting is that after the top plate 72 is installed to the top of the positioning plate 71, the top plate will not block the top-down installation of the second connecting member 23 at the top of the connection point.

[0084] In one embodiment, the driving structure 20 further includes a reducer 24 .

[0085] The speed reducer 24 is arranged on the frame 10 and between the power component 21 and the first connecting component 22, and the speed reducer 24 connects the first connecting component 22 with the power component 21.

[0086] In this embodiment, one end of the speed reducer 24 is connected to the output end of the power component 21, and the other end is connected to the first connecting component 22. The setting of the speed reducer 24 is used to control the output speed of the power component 21 so as to control the speed of the reel assembly 40.

[0087] In addition, a set of driving structures 20 are respectively arranged at both ends of the main shaft, and the corresponding slide rail assemblies 30, driving components 50, anti-collision frames 60, positioning frame assemblies 70 and action bottom plates 80 are also provided in a matching manner; it should be noted that the two sets of driving structures 20 need to be synchronized when driving the reel assembly 40.

[0088] The above description is only the implementation mode of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
