Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a winding mechanism and a slitting machine. Background Art

[0002] A slitting machine is a mechanical device that cuts wide-width paper, mica tape or film into multiple narrow-width materials.

[0003] The rewinding and rewinding of existing slitting machines are controlled by hydraulic cylinders, and only the forward pressure can be controlled by an electrical proportional valve.

This makes it difficult to control process parameters, leading to problems such as uneven rewinding ends and excessively stiff rewinding.

[0004] Therefore, a winding mechanism and a slitting machine are urgently needed to solve the above problems. Utility Model Content

[0048] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0049] Figure 1 A schematic structural diagram of a winding mechanism provided in an embodiment of the present utility model is shown; Figure 2 The following is a partial structural diagram of the winding mechanism provided by the embodiment of the present invention. Figure 1 and Figure 2 , this embodiment provides a winding mechanism and a slitting machine, and the slitting machine includes the winding mechanism provided in this embodiment. Figure 1 and Figure 2 The first direction shown in the figure is the direction of the line connecting the center points of the first scroll 100 and the second scroll 200. The first direction and the film movement direction do not coincide with each other, and the second direction is parallel to the axial extension direction of the first scroll 100 and the second scroll 200.

[0050] The winding mechanism includes a reel, a driving roller, an adjustment cylinder, and a control system. A film can be wound around the reel to form a film roll. The driving roller is spaced apart from the reel in the direction of film movement. The adjustment cylinder is connected to the reel and can drive the reel in the direction of film movement. The control system can receive a signal indicating the roll diameter of the film roll on the reel, control the pressure on the forward side of the adjustment cylinder, and the pressure on the backward side of the adjustment cylinder, and adjust the spacing between the reel and the driving roller.

[0051] Only one of the above-mentioned reels and active rollers can be provided to complete the winding. In the present embodiment, the reel includes a first reel 100 and a second reel 200, and the active roller includes a first active roller 600 and a second active roller 700. That is to say, in the present embodiment, the winding mechanism can be suitable for winding in two parts after slitting, one part is wound on the first reel 100, and the other part is wound on the second reel 200.

[0052] Specifically, the first reel 100 and the second reel 200 are arranged parallel to each other and spaced apart. The first active roller 600 is spaced apart from the first reel 100 along the film movement direction, and the second active roller 700 is spaced apart from the second reel 200 along the film movement direction. The regulating cylinder includes a first regulating cylinder 300 and a second regulating cylinder 400. The output end of the first regulating cylinder 300 is connected to the end of the first reel 100 and can drive the first reel 100 to move along the film movement direction; the output end of the second regulating cylinder 400 is connected to the end of the second reel 200 and can drive the second reel 200 to move along the film movement direction. When the film is wound, the large film is cut into small films, with some of the film being wound on the first reel 100 and some on the second reel 200. The first reel 100 and the second reel 200 are wound simultaneously.

[0053] It should be noted that when the roll diameter signal indicates that the roll diameter of the film roll is gradually increasing, the winding pressure applied by the active roller to the reel during the film roll winding process should be gradually reduced to avoid problems such as uneven winding end surfaces and excessive winding, thereby ensuring the winding quality. In other words, as the roll diameter of the film roll gradually increases, the control system can precisely control the spacing between the first reel 100 and the first active roller 600 in the direction of film movement, and precisely control the spacing between the second reel 200 and the second active roller 700 in the direction of film movement by controlling the pressure on the forward side of the first regulating cylinder 300, the pressure on the backward side of the first regulating cylinder 300, the pressure on the forward side of the second regulating cylinder 400, and the pressure on the backward side of the second regulating cylinder 400, thereby precisely controlling the winding pressure.

[0054] In addition, by using the first regulating cylinder 300 and the second regulating cylinder 400 to replace the traditional oil cylinder, and using a control system to control the first regulating cylinder 300 and the second regulating cylinder 400, precise control of the movement of the first regulating cylinder 300 and the second regulating cylinder 400 can be achieved, thereby improving the precise adjustment of the winding pressure during the winding process.

[0055] More specifically, the winding mechanism further includes a first regulating valve assembly (not shown) and a second regulating valve assembly (not shown). The first regulating valve assembly is capable of regulating the air volume on the forward side of the first regulating cylinder 300 and the air volume on the forward side of the second regulating cylinder 400. The second regulating valve assembly is capable of regulating the air volume on the backward side of the first regulating cylinder 300 and the air volume on the backward side of the second regulating cylinder 400. The control system is communicatively connected to the first regulating valve assembly and the second regulating valve assembly and is capable of controlling the opening of the first regulating valve assembly and the second regulating valve assembly. In this embodiment, both the first regulating valve assembly and the second regulating valve assembly can be pneumatic proportional valves.

[0056] The amount of retreat of the regulating cylinder should be calculated comprehensively based on the size of the current film roll's winding diameter and the amount of air on the forward side to ensure that the pressure applied by the regulating cylinder fully complies with the set value. That is, the first regulating valve assembly (not shown) and the second regulating valve assembly (not shown) are directly connected to the control system, which is controlled by the control system through signals, and the advance and retreat algorithms are programmed into the control system. As the winding diameter becomes larger and larger, the forward side pressure A will also change according to the taper calculation. In order to ensure that the actual pressure matches the set value B, a backward side pressure C needs to be applied to offset the unbalanced pressure on the forward side. In other words, AB=C, the above B is constant, and A and C will change through the control system control.

[0057] More specifically, the winding mechanism also includes an operating screen. This operating screen is communicatively connected to the control system and can display the film roll diameter signal, the forward pressure of the first regulating cylinder 300, the backward pressure of the first regulating cylinder 300, the forward pressure of the second regulating cylinder 400, and the backward pressure of the second regulating cylinder 400. The operating screen also integrates a command issuing function, through which the operator can issue commands to the control system, thereby manually setting the forward pressure of the first regulating cylinder 300, the backward pressure of the first regulating cylinder 300, the forward pressure of the second regulating cylinder 400, and the backward pressure of the second regulating cylinder 400 based on the film roll diameter signal, thereby controlling the spacing between the first reel 100 and the first active roller 600, and controlling the spacing between the second reel 200 and the second active roller 700. In this embodiment, the control system can specifically select a PLC controller, and its control principle is not detailed in this embodiment.

[0058] Continue to refer to Figure 1 and Figure 2 The winding mechanism further includes a mounting frame 500. Both ends of the first reel 100 are connected to the mounting frame 500 and can move along the film moving direction. Both ends of the second reel 200 are connected to the mounting frame 500 and can move along the film moving direction.

[0059] Specifically, the mounting frame 500 includes two support plates 530 that are parallel to each other and spaced apart in the second direction. The two ends of the first reel 100 are respectively connected to the two support plates 530, and the two ends of the second reel 200 are respectively connected to the two support plates 530. The two support plates 530 can provide a mounting base for the first reel 100 and the second reel 200.

[0060] More specifically, the mounting frame 500 further includes a reinforcing rod 540, the ends of which are connected to the two support plates 530, respectively. The reinforcing rod 540 is spaced apart from the first reel 100 and the second reel 200. The reinforcing rod 540 can ensure a constant spacing between the two support plates 530 in the second direction, thereby improving the structural reliability of the mounting frame 500.

[0061] Figure 3 Show Figure 2 A partial enlarged view of the structure marked as A. Figure 2 and Figure 3 A first mounting plate 110 is provided at each end of the first reel 100. A first slider 120 is provided on the side of the first mounting plate 110 facing away from the first reel 100. The mounting frame 500 is provided with a first slide rail 510 corresponding to the position of the first slider 120 along the film movement direction. The first slider 120 is slidably connected to the first slide rail 510.

[0062] Similarly, a second mounting plate 210 is provided at both ends of the second reel 200, a second slider 220 is provided on the side of the second mounting plate 210 facing away from the second reel 200, and a second slide rail 520 is provided on the mounting frame 500 corresponding to the position of the second slider 220 along the direction of film movement, and the second slider 220 is slidably connected to the second slide rail 520.

[0063] It should be noted that in this embodiment, the first slider 120 and the second slider 220 are both lightweight sliders, and the first slide rail 510 and the second slide rail 520 are both lightweight slide rails. This arrangement can effectively reduce the resistance of the first reel 100 and the second reel 200 when moving along the film moving direction.

[0064] Specifically, multiple groups of the first sliders 120 are arranged on the first mounting plate 110, each group includes multiple first sliders 120 arranged at intervals along the movement direction of the film, and the mounting frame 500 is provided with multiple first slide rails 510 corresponding to the position of the first mounting plate 110. The multiple first slide rails 510 are arranged at intervals in the first direction, and each group of the first sliders 120 corresponds to and is slidably connected to one of the first slide rails 510.

[0065] Similarly, multiple groups of the second sliders 220 are arranged on the second mounting plate 210, each group includes multiple second sliders 220 arranged at intervals along the direction of film movement, and the mounting frame 500 is provided with multiple second slide rails 520 corresponding to the position of the second mounting plate 210. The multiple second slide rails 520 are arranged at intervals in the first direction, and each group of the second sliders 220 corresponds to and is slidably connected to one of the second slide rails 520.

[0066] Through the above arrangement, the reliability of the sliding connection between the first mounting plate 110 and the first slide rail 510 can be ensured in the first direction, and the reliability of the sliding connection between the second mounting plate 210 and the second slide rail 520 can be ensured in the first direction.

[0067] More specifically, each set of first sliders 120 includes multiple first sliders 120 spaced apart along the film's direction of motion. That is, multiple first sliders 120 are arranged in a rectangular array on the first mounting plate 110, each capable of slidingly connecting to the first slide rail 510, thereby further improving the smooth movement of the first mounting plate 110. Each set of second sliders 220 includes multiple second sliders 220 spaced apart along the film's direction of motion. That is, multiple second sliders 220 are arranged in a rectangular array on the second mounting plate 210, each capable of slidingly connecting to the second slide rail 520, thereby further improving the smooth movement of the second mounting plate 210.

[0068] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
