Description

Technical Field

[0001] The utility model relates to the field of graphene film production, and in particular to an integrally movable slitting and rolling-up integrated mechanism, which is used for cutting and rolling up graphene films. Background Art

[0002] The chemical preparation of graphene film requires the steps of pulping, coating into original film, calendering, and heat treatment. After coating into original film, calendering, and heat treatment, the film material will be cut and rolled up in the transfer process or packaging and shipping process to ensure product yield and save transportation costs. The traditional fixed slitting and rolling method has the following problems: when there are defects on both sides of the film material or the margins on both sides are uneven after entering the slitting-rolling mechanism, it is easy to cause part of the film material to be scrapped. Taking the cutting and winding after coating as an example, after the slurry is coated and dried by the coater, the original film produced is several meters long. Burrs, cracks, uneven coating thickness and other undesirable phenomena may appear on both sides of the edge of the film. If the cutting position and winding position are not adaptively adjusted in time to address the defects, it is easy to cause the film on both sides of the edge to be scrapped. At the same time, since the transmission of the film material in the coater is not a completely straight state, the position of the film material will also be relatively offset during the transmission process after it is directly transmitted from the coater outlet to the slitting-winding mechanism. If it is forced to perform fixed slitting and winding, it will cause wrinkles and poor size of the film material, which will directly cause the entire film material to be scrapped.

[0030] The technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0031] The purpose of the utility model is to provide a slitting and winding integrated mechanism that can be moved as a whole to solve the problem of product defects caused by fixed slitting and winding. The specific structure includes:

[0032] Support base plate;

[0033] The slitting mechanism comprises a slitting spindle and at least two sets of slitting cutter discs arranged on the slitting spindle, wherein the slitting cutter discs can move on the slitting spindle;

[0034] The winding mechanism comprises a winding main shaft and at least one set of winding shafts arranged on the winding main shaft, wherein the winding shafts can move on the winding main shaft;

[0035] A linear sliding mechanism, the slitting mechanism and the winding mechanism are mounted on the linear sliding mechanism, and the linear sliding mechanism drives the slitting mechanism and the winding mechanism to move horizontally on the supporting bottom plate at the same time;

[0036] A linear adjustment mechanism controls the linear sliding mechanism to move horizontally on the supporting base plate.

[0037] In the embodiment of the utility model, the support base plate is used to support the entire mechanism to make it integrated, which is convenient for fixing and carrying, and at the same time increases the floor space of the mechanism to enable it to be placed stably.

[0038] In some embodiments of the present invention, in order to accurately control the cutting size, scales are provided on the slitting spindle and the winding spindle;

[0039] In the embodiment of the present invention, the number of slitting knife discs is determined according to the final number of film materials to be cut. Generally speaking, the number of slitting knife discs is one more than the final number of film materials required. If the entire film material needs to be cut into 4 parts in the end, then the slitting knife discs should be set to 5 sets. The purpose of this setting is to fix two sets of slitting knife discs on the edge to remove burrs, uneven thickness and other defects on the edge of the film material.

[0040] In some embodiments of the present invention, the slitting blade disc is made of tungsten steel. The purpose of this is that the tungsten steel wears less and can ensure the slitting quality of the thermal conductive film. At the same time, the blade disc has a longer service life, which reduces the frequency of blade replacement and improves slitting efficiency.

[0041] In the embodiment of the present invention, the number of winding shafts is determined according to the number of film materials to be slit. Generally speaking, the number of winding shafts is consistent with the number of film materials to be slit, so as to facilitate the winding of the film materials.

[0042] In some embodiments of the utility model, the winding shaft is an inflatable shaft, and an inflatable locking screw is provided on the inflatable shaft to flexibly adapt to winding cores of different specifications.

[0043] In some embodiments of the utility model, drivers are installed on the slitting blade disc and the winding shaft, thereby avoiding manual adjustment of the positions of the slitting blade disc and the winding shaft and improving work efficiency.

[0044] In the embodiments of the utility model, the linear sliding mechanism serves to set up the slitting mechanism and the winding mechanism, and drives the slitting mechanism and the winding mechanism to move as a whole on the supporting floor. In some specific embodiments, a guide rail is installed on the supporting bottom plate, and a pulley is installed at the bottom of the linear sliding mechanism. The pulley is adapted to the slide rail to reduce friction.

[0045] In an embodiment of the utility model, a linear adjustment mechanism controls the linear sliding mechanism to move horizontally on the support base plate. The structure of the linear adjustment mechanism is not limited. The driver can be directly installed on the bottom end of the linear sliding mechanism, or it can be in other forms. In a specific embodiment of the utility model, the adjustment mechanism is as follows: it includes a first mounting support, a movable adjustment screw movably arranged on the first mounting support, and a second mounting support rotatably connected to the movable adjustment screw. The first mounting support is fixedly connected to the support base plate, the second mounting support is fixedly connected to the linear sliding mechanism, the movable adjustment screw is connected to the first mounting support by means of a thread, and an adjustment handwheel is also installed on the side of the movable adjustment screw away from the second mounting support to facilitate control and adjustment.

[0046] The content of the utility model is further described below in conjunction with specific examples, but it should not be construed as limiting the utility model. If not specifically indicated, the technical means used in the examples are conventional means well known to those skilled in the art. Unless otherwise specified, the reagents, methods and equipment used in the utility model are conventional reagents, methods and equipment in the art. Example 1

[0047] The integrally movable slitting and winding mechanism provided in this embodiment is compatible with the coating line.

[0048] See attached Figure 1 , a slitting and winding integrated mechanism that can be moved as a whole, comprising:

[0049] A support base plate 1, on which a slide rail 11 is arranged;

[0050] Slitting mechanism 2, see Figure 2 , including a slitting spindle 21 and five sets of slitting blade discs 22 arranged on the slitting spindle 21, so as to slit the entire coated original film into four equal parts, the slitting blade disc can move on the slitting spindle, and the slitting blade disc is a round slitting blade made of tungsten steel;

[0051] Winding mechanism 3, see Figure 3 , including a winding main shaft 31 and four winding shafts 32 arranged on the winding main shaft, the winding shaft 32 is an air shaft, and an air locking screw 321 is provided on the air shaft. At the same time, it also includes a motor 33, which drives the winding main shaft 31 to rotate for winding;

[0052] A linear sliding mechanism 4, on which the slitting mechanism 2 and the winding mechanism 3 are mounted, can simultaneously drive the slitting mechanism 2 and the winding mechanism 3 to move horizontally on the supporting bottom plate 1. In order to reduce the friction during movement, a pulley 41 is also provided under the linear sliding mechanism 4, and the pulley 41 is just adapted to the slide rail 11 installed on the supporting bottom plate;

[0053] A linear adjustment mechanism 5, wherein the linear adjustment mechanism 5 controls the linear sliding mechanism 4 to move horizontally on the supporting base plate 1. Since the width of the coated original film is relatively large and the slitting and winding machine is too heavy as a whole, a driver is not used in this embodiment to drive the linear sliding mechanism 4 to move. In this embodiment, the linear adjustment mechanism 5 includes a first mounting support 51, a movable adjustment screw 52 movably inserted into the first mounting support, and a second mounting support 53 rotatably connected to the movable adjustment screw 52. The first mounting support 51 is welded to the supporting base plate 1, and the second mounting support 53 is welded to the linear sliding mechanism 4. The movable adjustment screw 52 has a threaded portion 521, a clamping portion 522 and a smooth portion in the middle section (not shown in the figure) respectively arranged at both ends. The threaded portion 521 of the movable adjustment screw is connected to the first mounting support 51 by means of a thread; the specific rotational connection method of the movable adjustment screw and the second mounting support is as follows: Figure 4 As shown in the figure, a hole is set on the second mounting support 53, and the aperture of the hole is larger than the smooth part on the movable adjustment screw 52, and smaller than the threaded part and the clamping part on the movable adjustment screw 52, so as to realize the idling of the movable adjustment screw 52 in a relatively fixed position on the second mounting support 53, and an adjusting hand wheel 54 is also installed on the side of the movable adjustment screw away from the second mounting support.

[0054] The working state of the integrally movable slitting and winding mechanism is as follows:

[0055] When the coated original film 6 is transmitted from the coating machine (not shown) to the mechanism, since the transmission speed of the coating machine is relatively slow, usually 0.5-1.0 m / min, there is sufficient time to observe the state of the coated original film. When it is found that the coated original film has defects such as burrs, or when it is found that the transmission of the coated original film does not follow the ideal path, the position of the slitting knife disc and the air shaft is adjusted in time, or the adjustment hand wheel 54 is turned in time to drive the linear sliding mechanism 4 and even the slitting mechanism 2 and the winding mechanism 3 to move in the horizontal direction, thereby completing the cutting of the coated original film. Example 2

[0056] This embodiment provides the original coating film that has been cut and rolled up in Embodiment 1.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
