Description

Technical Field

[0001] This technical solution relates to the field of cutting and slitting machines, and specifically refers to a winding device for a cutting and winding machine. Background Technology

[0002] A slitting machine is an automated device specifically designed for the efficient processing of materials such as paper (e.g., kraft paper). Through precise slitting and winding functions, it cuts wide-width raw paper to preset dimensions and then synchronously winds it onto a spool by a constant tension control system, ensuring uniform slitting width and neat and tight winding.

[0003] When existing cutting and slitting machines wind multiple slits through a multi-station winding device, the independent drive of each winding drum and the lack of a dynamic tension coordination mechanism result in differences in linear speed between different winding devices. This leads to uneven tension between the winding layers of the slits, as well as problems such as edge stacking or local depressions, resulting in poor finished product quality, which needs to be improved. Summary of the Invention

[0004] This technical solution aims to improve the problem of uneven winding of multi-station independently wound strips due to the lack of dynamic tension coordination, and provides a winding device for a cutting and winding machine.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A winding device for a cutting and winding machine, the winding device comprising: a winding frame;

[0007] A winding assembly is disposed on the take-up frame. The winding assembly includes a take-up drum and a winding drive. The take-up drum rotates relative to the take-up frame, and the winding drive drives the take-up drum to rotate to perform a strip winding operation.

[0008] The wire laying mechanism includes a wire laying frame, a sliding rod connected to the wire laying frame, and a wire laying drive component. The wire laying frame is slidably disposed relative to the winding frame. The sliding rod is laterally mounted on the winding frame. A guide wire frame is provided on the sliding rod. The guide wire frames are arranged one by one corresponding to the positions of the winding components and are used to guide the material strip to the winding drum.

[0009] The wire laying drive unit drives the wire laying frame to move back and forth, so that the sliding rod drives the wire frame to move synchronously, thereby realizing the uniform winding and distribution of the material strip on the winding drum.

[0010] Through the above technical solution, when the winding device of a cutting and winding machine is in normal use, the winding drive drives the winding drum to rotate at a uniform speed to wind the material strip. At the same time, the wire laying drive drives the wire laying frame to slide back and forth along the winding frame, which drives the wire guide frame on the sliding rod to move laterally in sync. The wire guide frame accurately guides the direction of the material strip at each station by corresponding to the position of the winding drum, so that the material strip forms a uniform arrangement on the surface of the winding drum with the regular displacement of the wire guide frame. This realizes the tension balance and space distribution optimization of the material strip at multiple stations during the winding process, and improves the forming quality and winding efficiency of the roll material.

[0011] Preferably, the winding frame further includes a transmission assembly, the transmission assembly comprising:

[0012] The cable guide rail is installed on the winding frame;

[0013] A cable slider, which slides in conjunction with the cable guide rail and is connected to the cable frame;

[0014] A lead screw is threadedly engaged with the cable slide block and connected to the output end of the cable drive component. The lead screw rotates relative to the winding frame, and the cable drive component drives the lead screw to rotate in order to drive the cable slide block to slide, thereby causing the lead frame to move back and forth.

[0015] Through the above technical solution, the wire laying drive drives the lead screw to rotate, and through the threaded engagement with the wire laying slider, the rotational motion of the lead screw is converted into the horizontal linear motion of the wire laying slider along the wire laying rail. By changing the rotation direction, the slider can move forward or backward, forming a precise and stable reciprocating motion, realizing the equidistant arrangement of the material strip on the surface of the winding drum, and improving the uniformity of wire laying.

[0016] Preferably, the winding frame is provided with a roller assembly, which includes two rollers, both of which rotate relative to the winding frame. The rotation axes of the two rollers are parallel to each other, and a channel for the sliding rod to pass through is formed between the two rollers.

[0017] Through the above technical solution, the horizontal movement of the sliding rod needs to pass through the channel formed by two parallel rollers. The sliding friction between the sliding rod and the winding frame is transformed into low-resistance rolling friction through rolling contact. The two-way wrapping guide of the rollers provides a supporting foundation, constrains the lateral offset of the sliding rod, ensures its linear accuracy in high-speed reciprocating motion, reduces mechanical wear, and optimizes the power transmission efficiency of the cable laying mechanism.

[0018] Preferably, the conductor frame is equipped with conductor wheels.

[0019] Through the above technical solution, the guide frame is equipped with guide wheels and a rolling guide strip for winding.

[0020] Preferably, the winding frame is equipped with a thread stabilizer, which has a plurality of thread stabilizing guides, each of which is arranged one-to-one with the lead frame to guide the paper strip to the lead roller.

[0021] Through the above technical solution, the material strip is first guided by the stabilizing guide head and then enters the annular groove of the corresponding guide wheel, forming a two-stage guiding path from feeding to winding. During the process of distributing the material strip to the corresponding winding drum, the stabilizing guide head further constrains the material strip and performs secondary dynamic correction.

[0022] Preferably, the winding frame is provided with a roller frame, which is located on the top of the winding frame. The roller frame is provided with a plurality of thread guide rollers for guiding the paper strip, and each thread guide roller is provided in a corresponding manner to the thread guide head.

[0023] Through the above technical solution, the wire feeding wheel, the wire stabilizing guide, and the guide wheel form a three-level guide chain. The material strip is distributed and guided to the corresponding wire stabilizing guide through the wire feeding wheel on the wire feeding wheel frame, and then guided to the guide wheel of the corresponding guide frame through the wire stabilizing guide. By suppressing high-speed swing through step-oriented orientation, the wire entry angle of the material strip is kept constant, and the neatness of the end face of the roll and the density between layers are improved.

[0024] Preferably, the winding frame is provided with a mounting bracket, and the winding drum is rotatably mounted on the mounting bracket. The winding drum has an axially penetrating shaft hole, in which a drum shaft can pass. The mounting bracket includes:

[0025] The mounting base is provided with a locking block that fits into the cylindrical shaft;

[0026] A swing handle, which is hinged to the mounting base, has a through hole for the passage of the cylinder shaft on the other side;

[0027] A torsion spring is provided at the hinge between the mounting base and the swing handle. The spring force of the torsion spring causes the locking block to tend to engage with the cylinder shaft.

[0028] Through the above technical solution, the torsion spring pushes the swing handle to rotate towards the winding drum through the elastic preload, so that the clamping block automatically engages with the drum shaft to achieve rapid positioning and clamping of the winding drum. The other end of the drum shaft passes through the through hole and is rotatably connected in the through hole. When changing, the outer swing handle compresses the torsion spring, and the clamping block disengages from the drum shaft, so the winding drum can be pulled out. The dynamic self-locking mechanism realizes tool-free disassembly and assembly of the winding drum, ensuring rigid support during high-speed rotation, improving winding efficiency, and ensuring the continuity of winding operations and the stability of forming quality.

[0029] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0030] 1. This technical solution uses a wire-laying drive to drive the wire-laying frame to slide back and forth along the winding frame, which in turn drives the wire guide frame on the sliding rod to move laterally in sync. The wire guide frame precisely guides the direction of the material strips at each station by corresponding to the position of the winding drum, so that the material strips are evenly distributed on the surface of the winding drum with the regular displacement of the wire guide frame, thereby improving the forming quality and winding efficiency of the roll material.

[0038] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0039] Example:

[0040] See Figure 1 and Figure 2A winding device for a cutting and winding machine includes a winding frame 1. In this embodiment, the winding frame 1 is divided into two winding machines with similar structures and placed parallel to each other along the length direction. The winding frame 1 is provided with winding components 2, and there are multiple of them. In this embodiment, the winding components 2 are arranged in a two-dimensional array of twelve columns (longitudinal) × five rows (transverse), so that each column is equipped with five winding components 2, realizing multi-station synchronization, and can also form other modular layouts.

[0041] See Figure 3 , Figure 4 and Figure 5 Each winding assembly 2 includes a take-up drum 21 and a winding drive 22, preferably a motor, which is mounted on a take-up frame 1. The take-up frame 1 is also provided with a mounting frame 13. The take-up drum 21 is detachably mounted on the mounting frame 13 and rotatably connected to the mounting frame 13. The mounting frame 13 includes a mounting base 131, a swing handle 132 hinged to the mounting base 131, and a torsion spring 133 disposed between the mounting base 131 and the swing handle 132. The mounting base 131 is L-shaped, and its vertical portion has a through hole 17 through which the take-up drum 21 axially passes. A shaft hole 14 is passed through, and a cylindrical shaft 15 can be inserted into the shaft hole 14. The swing handle 132 is rotated to overcome the elastic force of the torsion spring 133. One end of the cylindrical shaft 15 passes through the through hole 17 and is rotated within the through hole 17. When the swing handle 132 is released, the elastic force of the torsion spring 133 causes the swing handle 132 to tend to abut against the winding drum 21. A locking block 16 is provided at the other end of the swing handle 132 corresponding to the cylindrical shaft 15. The locking block 16 has a locking groove. The cylindrical shaft 15 is inserted into the locking groove to achieve engagement with the locking block 16, restricting the other end of the coaxial shaft from rotating within the locking groove, thereby realizing the placement of the winding drum 21.

[0042] One end of the cylinder shaft 15 extends out of the through hole 17 and extends to the outside of the mounting base 131. The output end of the winding drive 22 is connected to the cylinder shaft 15 through a transmission belt, so that the winding drive 22 can drive the take-up cylinder 21 to rotate and thus wind the paper strip.

[0043] See Figure 1 and Figure 6It also includes a cable laying mechanism 3, which is mounted on the take-up frame 1. The cable laying mechanism 3 includes a cable laying frame 31, a sliding rod 32, a cable laying slider 52, and a cable laying drive 33. The cable laying frame 31 is slidably arranged relative to the cable laying seat, and the sliding direction is horizontally back and forth. There are multiple sliding rods 32, and each sliding rod 32 is arranged one-to-one with each row of winding assembly 2. In this embodiment, there are ten sliding rods 32, which are symmetrically fixed on both sides of the cable laying frame 31. Each sliding rod 32 on each side is arranged one-to-one with each row of winding assembly in the winding mechanism on the corresponding side. The take-up frame 1 is provided with multiple roller assemblies 6. Each roller assembly 6 includes two rollers 61. The rotation axes of the two rollers 61 are parallel. The sliding rod 32 passes between the two rollers 61, so that the sliding rod 32 can be laterally moved on the take-up frame 1 through the roller assembly 6.

[0044] The winding frame 1 is also equipped with a transmission component 5, which includes a cable laying slide rail 51, a cable laying slider 52, and a lead screw 53. The cable laying slide rail 51 includes two parts. The cable laying slider 52 is slidably connected to the winding frame 1 through the cable laying slide rail 51. Its sliding direction is parallel to the sliding direction of the cable laying frame 31. The cable laying drive 33 is installed on the winding frame 1. The cable laying drive 33 is preferably a motor. The lead screw 53 is connected to the output end of the cable laying drive 33. The lead screw 53 is rotatably set relative to the winding frame 1. The lead screw 53 is threadedly connected to the cable laying slider 52. The cable laying drive 33 drives the lead screw 53 to rotate. The lead screw 53 drives the cable laying slider 52 to move forward or backward in different rotation directions, thereby causing the cable laying frame 31 to reciprocate in the front-back direction, and thus driving all the sliding rods 32 to move synchronously.

[0045] See Figure 2 and Figure 3 The take-up frame 1 is provided with a roller frame 11, and there are multiple roller frames 11. The multiple roller frames 11 are arranged one-to-one with multiple rows of winding components 2. Each roller frame 11 is installed at intervals on the top of the take-up frame 1. Each roller frame 11 is provided with multiple thread guide wheels 12, and there are five thread guide wheels 12. The five thread guide wheels 12 are arranged one-to-one with the five rows of winding components 2 in the corresponding column to guide the paper strip.

[0046] The winding rack 1 is equipped with a thread stabilizer 9. Multiple thread stabilizers 9 are installed on each sliding rod 32. The multiple thread stabilizers 9 correspond one-to-one with multiple roller frames 11. Each thread stabilizer 9 has a thread guide head 10. The number of thread guide heads 10 is one less than the number of rollers 12. In this embodiment, four thread guide heads 10 are shown. The thread guide heads 10 are used for paper strips to pass through one-to-one.

[0047] Each sliding rod 32 is equipped with a guide rail 4, and there are multiple guide rails 4. Each guide rail 4 corresponds to a number of winding components 2. Each guide rail 4 is equipped with two guide rail wheels 8. The two guide rail wheels 8 are rotatably connected to opposite ends of the guide rail 4 along its length, and the rotation axes of the two guide rail wheels 8 are parallel to each other. Every five paper strips are first guided by five guide rails 12. One guide rail 8 guides one paper strip to the top guide rail 8, and the other four guide rails 12 guide four paper strips through four stabilizing guide heads 10. The four stabilizing guide heads 10 guide four paper strips to the four guide rails 4 in the corresponding column for the second guidance. The guide rail 4 guides the paper strips to the corresponding take-up drum 21 through the guide rail wheels 8 for the third guidance, thereby achieving stable winding of the line on the take-up drum 21.

[0048] The specific work process of this plan is as follows:

[0049] This technical solution uses a winding drive 22 to drive the take-up drum 21 to rotate at a uniform speed to wind the material strip. At the same time, the wire laying drive 33 drives the wire laying frame 31 to slide back and forth along the take-up frame 1, which drives the guide wire frame 4 on the sliding rod 32 to move laterally in sync. The guide wire frame 4 precisely guides the direction of the material strip at each station by corresponding to the position of the take-up drum 21, so that the material strip is evenly distributed on the surface of the take-up drum 21 with the regular displacement of the guide wire frame 4. This realizes the tension balance and space distribution optimization of the material strip at multiple stations during the winding process, and improves the forming quality and winding efficiency of the roll material.

Those skilled in the art should understand that this technical solution is not limited to the above embodiments.
