Description

Technical Field

[0001] The invention relates to the technical field of cloth rolling, and in particular to a cloth folding and rolling machine capable of automatically splicing materials. Background Art

[0002] The automatic fabric folding and rolling machine is a device for automatically folding and rolling fabrics. It is usually used in production lines in the textile, clothing, home textile and other industries. It introduces the fabric from the feed end into the machine through an automatic control system. After a series of folding and rolling operations, the fabric is finally neatly folded and rolled into a roll for subsequent packaging, storage or transportation. In the Chinese patent with patent announcement number CN110510437B, a manual cloth winding machine is disclosed, which includes a base, a mounting plate, a support column, a bearing seat, a slotted tube, a first pressing plate, etc.; a mounting plate is fixedly connected to the middle rear side of the top of the base, and a bearing seat is fixedly connected to the top of the mounting plate. By placing the head end of the cloth into the slotted tube and fixing it through a clamping device, the handle is shaken and rotated, so that the slotted tube can be rotated to roll up the cloth. After the cloth is rolled up, it can be taken off the slotted tube. There is no need for a person to hold the cylinder with one hand and hold the cloth with the other hand to roll it on the cylinder, which is more convenient. In addition, through the action of the roller, the cloth can be kept in a tight state, so that the cloth can be rolled up in the slotted tube more neatly. However, the devices in the above-mentioned reference documents and the devices in the prior art still have the following defects when used: 1. The equipment in the comparative document fixes the head end of the fabric by placing it into a slotted tube and clamping it. Since the fabric has a long weaving length, the fabric is usually wound around the winding roller layer by layer, and in order to improve the rotation stability of the winding roller, the roller is usually rotatably mounted on the frame through bearings, connecting rods, bearing covers and other parts. Therefore, although the clamping end method in the comparative document can achieve rapid fixation of the fabric, the initial clamping of the end will lead to low efficiency in removing the fabric roll later, thereby affecting the normal winding efficiency of the equipment; 2. In the prior art, the feeder and the take-up frame are controlled by different drive sources respectively. Although they are equipped with tension adjustment devices, as the amount of fabric on the take-up shaft increases, the independent driving of the two makes it difficult to match the speeds, and it is difficult to ensure synchronization and coordination. The fabric will be subjected to uneven tension or pressure during the transmission process. Although the tension adjustment can balance it to a certain extent, as the fabric accumulates, the take-up radius increases. If it is not adjusted in time, the fabric will easily produce a speed difference between conveying and taking-up, thereby forming wrinkles.

[0003] In view of this, the present invention proposes a cloth folding and rolling machine with automatic material splicing to make up for and improve the deficiencies of the prior art. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a cloth folding and rolling machine with automatic material splicing to solve the technical problems raised in the above background technology.

[0006] Furthermore, the winding assembly as a whole is composed of a double-axis motor at the bottom and a combination of round rollers symmetrically arranged on the surface, and the feeder and the winding assembly are both electrically controlled by a control console.

[0007] Furthermore, the dynamic balancing mechanism includes a three-dimensional bracket symmetrically and slidably connected to the upper surface of the winding assembly, the interior of the three-dimensional bracket is penetrated by a limiting main shaft that is rotatably connected, the exterior of the limiting main shaft is threadedly connected with a nut sleeve rod, and the sides of the nut sleeve rod that are close to each other are slidably connected with a movable pin, the lower end of the limiting main shaft is fixedly connected with a driven gear, the exterior of the driven gear is meshed with a driving gear, and the driving gear is fixedly connected to the output shaft end of the dual-axis motor in the winding assembly.

[0008] Furthermore, the upper end of the limiting spindle is threaded, the lower end of the limiting spindle is smooth cylindrical, the nut sleeve rod and the upper end of the limiting spindle constitute a ball screw structure, and the nut sleeve rod is located at the bottom of the threaded outer wall of the limiting spindle.

[0009] Furthermore, the movable latch is in the shape of a right cross as a whole, and the sides of the movable latches close to each other are fixedly connected with cylindrical protruding shafts.

[0010] Furthermore, the dynamic adjustment mechanism includes a spring shaft fixedly connected to the side of the three-dimensional bracket that is close to each other, and an elastic arc plate is fixedly connected to the side of the spring shaft that is close to each other. The end of the elastic arc plate away from the spring shaft is in an inclined arc shape, and the elastic arc plate and the three-dimensional bracket are rotationally connected through the spring shaft.

[0011] Furthermore, the dynamic winding mechanism includes a support shaft installed above the winding assembly, a stress shell is fixedly connected to the top of the support shaft, a connecting ring is symmetrically slidably connected to the outer wall of the support shaft, a hinge group is evenly hinged to the lower outer wall of the connecting ring, and a contraction shell is hinged at one end of the hinge group away from the connecting ring.

[0012] Furthermore, cross slots are provided on both sides of the support shaft at positions corresponding to the movable latches, the support shaft and the nut sleeve rod are slidably connected via the movable latches, and the connecting ring is fixedly connected to the cylindrical protruding shaft on the side wall of the movable latch.

[0013] Furthermore, the hinge group is composed of two mutually staggered round rods, and the intersection of the round rods is movably connected through a hollow ball, and the size of the two ends of the hinge group is half of the middle size.

[0014] Furthermore, the shrinkage shell is initially in an extended state, a regular circle is formed between the shrinkage shell and the stress shell, and a movable clamp is installed at the bottom of the shrinkage shell.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In order to solve the problem that the rolled cloth is difficult to remove, before the cloth is rolled, the present device first uses the movable clamping plate provided on the outer wall of the shrinking shell to quickly fix the cloth end; secondly, when the cloth is rolled, a circular shell composed of a stress shell and a shrinking shell is installed on the outside of the support shaft, so that the cloth remains stable during the entire rolling process, reducing the damage to the cloth caused by mechanical vibration or instability; finally, after the cloth is rolled, the distance from the movable clamping plate is increased by moving the shrinking shell, so that the cloth end can be automatically released, avoiding the cumbersome process of the traditional clamping device requiring additional operations when removing the cloth; then, the stability of the cloth roll removal is maintained based on the support of the stress shell, and the gap formed by the movement of the shrinking shell is prepared for the subsequent removal of the cloth roll; Compared with the fixing and removal methods in the prior art, this design realizes the rapid fixing and release of the fabric end, paving the way for the subsequent removal of the fabric roll, thereby greatly improving the automation of the equipment, reducing the need for manual intervention, and further improving production efficiency and convenience of operation; Among them, the staggered round rod structure can increase the stability and load-bearing capacity of the hinged group, and the hollow ball movable connection at the intersection of the round rods can make the hinged group stable when subjected to external forces and pressures, reduce vibration and deformation, and improve the overall load-bearing capacity and working stability. The size of the two ends of the round rod is half of the middle size, which helps to reduce the overall weight while ensuring the structural strength. (2) In order to solve the problem of unbalanced tension in the prior art, the present device uses the connection and coordination between the movable latch and the support shaft so that the cloth is constantly raised along with the nut sleeve during the winding process. This design has three major advantages: First, the fabric is continuously raised during the winding process, thereby ensuring that the fabric is always tangent to the round roller in the winding assembly, thereby effectively reducing the friction during the winding process. This adaptability helps to avoid excessive friction on the fabric during the winding process, reduces wear and damage to the fabric, and improves the quality and integrity of the fabric; Second, as the fabric winding height continues to increase, the winding tension gradually increases. By gradually increasing the winding tension, it is helpful to form a uniform tension distribution on the fabric surface, and the gradually increasing tension maintains a balance with the gravity of the conveyed fabric itself, so that the fabric maintains a stable torque distribution during the winding process, thereby avoiding wrinkles caused by uneven torque; Thirdly, when the rolled fabric rises to the top, the movable pin can be directly pulled out from one side of the support shaft, and the three-dimensional bracket can be moved to stagger with the rolled fabric, thereby cooperating with the gap formed by the movement of the above-mentioned shrinking shell to realize the rapid disassembly of the fabric, thereby reducing the equipment downtime and improving the efficiency of the entire production process; (3) The device can effectively prevent impurities from remaining or being damaged during the winding process of the fabric through the dynamic fitting between the elastic arc plate and the fabric. Secondly, the collected impurities can move smoothly along the inclined arc of the elastic arc plate, making it convenient to collect and process them. In addition, when the elastic arc plate contacts the fabric, a certain pressure distribution can be generated. This pressure distribution helps to form a uniform pressure layer on the surface of the fabric, so that the fabric remains flat during the winding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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;

[0019] Example 1

[0020] Please refer to Figure 1 to Figure 2 As shown, an automatic material receiving and folding and rolling machine for fabric is used for rolling up a fabric body 13, comprising a feeder 1, a control console 11 is installed on the side wall of the feeder 1, a rolling assembly 12 is installed on the front side of the feeder 1, a dynamic balancing mechanism 2 is symmetrically arranged on the upper surface of the rolling assembly 12, a dynamic adjustment mechanism 3 is arranged on the side of the dynamic balancing mechanism 2 close to each other, and a dynamic rolling mechanism 4 is arranged above the rolling assembly 12; It should be noted that the winding assembly 12 as a whole is composed of a double-axis motor at the bottom and a combination of round rollers symmetrically arranged on the surface, and the feeder 1 and the winding assembly 12 are both electrically controlled by the control console 11.

[0021] Please refer to Figures 3 to 6 As shown, the dynamic balancing mechanism 2 includes a three-dimensional bracket 21 which is symmetrically and slidably connected to the upper surface of the winding component 12. The interior of the three-dimensional bracket 21 is penetrated by a limiting main shaft 22 which is rotatably connected. The exterior of the limiting main shaft 22 is threadedly connected with a nut sleeve rod 23. The sides of the nut sleeve rod 23 which are close to each other are slidably connected with a movable pin 24. The lower end of the limiting main shaft 22 is fixedly connected with a driven gear 25. The exterior of the driven gear 25 is meshed with a driving gear 26. The driving gear 26 is fixedly connected to the output shaft end of the dual-axis motor in the winding component 12.

[0022] It should be noted that the upper end of the limit spindle 22 is threaded, the lower end of the limit spindle 22 is smooth cylindrical, the nut sleeve rod 23 and the upper end of the limit spindle 22 form a ball screw structure, the nut sleeve rod 23 are located at the bottom of the threaded outer wall of the limit spindle 22, the movable latch 24 is in a right cross shape as a whole, and the sides of the movable latches 24 close to each other are fixedly connected with cylindrical convex shafts; Specifically, since the feeder 1 and the double-axis motor in the winding assembly 12 are in synchronous operation, when the cloth body 13 is continuously output from the inside of the feeder 1 and wound above the winding assembly 12, as the output shaft ends on both sides of the double-axis motor continue to rotate, the driven gear 25 will rely on the driving gear 26 to rotate simultaneously with the double-axis motor. At this time, the rotating limit spindle 22 will drive the nut sleeve rod 23 located at the threaded part to move vertically upward along the outer wall of the limit spindle 22. Since the nut sleeve rod 23 is slidably connected to the The interior of the support shaft 41, therefore, under the action of the movable latch 24 as an intermediate connector, the support shaft 41 will move upward synchronously with the nut sleeve rod 23, so that in the process of winding the cloth body 13, the thickness of the cloth body 13 will change, and the winding height will gradually increase, thereby ensuring that the cloth body 13 is always tangent to the round roller in the winding assembly 12, avoiding excessive friction of the cloth body 13 during the winding process, reducing the wear and damage of the cloth body 13, and improving the quality and integrity of its own winding.

[0023] Example 2

[0024] Based on Example 1, please refer to Figure 7 and Figure 8 As shown, the dynamic adjustment mechanism 3 includes a spring shaft 31 fixedly connected to the side of the three-dimensional bracket 21 close to each other, and an elastic arc plate 32 is fixedly connected to the side of the spring shaft 31 close to each other; It should be noted that the end of the elastic arc plate 32 away from the spring shaft 31 is in an inclined arc shape, and the elastic arc plate 32 and the three-dimensional bracket 21 are rotationally connected through the spring shaft 31 .

[0025] Specifically, the elastic arc plate 32 is movably connected to the inner wall of the three-dimensional bracket 21 through the spring shaft 31, and in the initial state, the elastic arc plate 32 is attached to the outermost side of the cloth body 13 outside the support shaft 41, and in the continuous winding process, the elastic arc plate 32 is supported by the elastic force of the spring shaft 31 itself, and still maintains dynamic changes. It will change its own position as the cloth body 13 is continuously expanded after the cloth body 13 is wound outside the support shaft 41, thereby ensuring that the elastic arc plate 32 is always attached to the outermost side of the cloth body 13, thereby effectively avoiding the situation where impurities remain or the cloth body 13 is damaged during the winding process. In addition, when the stress shell 42 contacts the cloth body 13, a certain pressure distribution can be generated, and this pressure distribution helps to form a uniform pressure layer on the surface of the cloth body 13, so that the cloth body 13 remains flat during the winding process.

[0026] Example 3

[0027] Based on Example 1 and Implementation 2, please refer to Figures 9 to 11 As shown, cross slots are provided on both sides of the support shaft 41 at positions corresponding to the movable latch 24 , the support shaft 41 and the nut sleeve rod 23 are slidably connected through the movable latch 24 , and the connecting ring 43 is fixedly connected to the cylindrical protruding shaft on the side wall of the movable latch 24 .

[0028] It should be noted that the shrink shell 45 is initially in an extended state, a regular circle is formed between the shrink shell 45 and the stress shell 42, and a movable splint is installed at the bottom of the shrink shell 45; Specifically, when the cloth body 13 is to be wound up, firstly, its end portion is passed through the movable splint at the bottom of the contraction shell 45, and the end portion is limited, and then the control console 11 is started to ensure that the feeder 1 is in a state of continuously conveying the cloth body 13. At this time, the support shaft 41 is also in a state of continuous rotation by relying on the dual-axis motor in the winding assembly 12, thereby ensuring that the cloth body 13 output from the inside of the feeder 1 is continuously wound up on the outside of the circular shell formed by the stress shell 42 and the contraction shell 45. When the support shaft 41 moves to the top of the three-dimensional bracket 21 following the nut sleeve rod 23, the winding work is completed. At this time, the staff pulls the movable latch 24 to move it toward the direction of the nut sleeve rod 23. In this process, the cylindrical convex shaft in the movable latch 24 will synchronously drive the connecting ring 43 to move in the direction of the nut sleeve rod 23, and when the connecting ring 43 moves During the process, the hinge group 44 is continuously pulled, and then the shrinking shell 45 is ensured to shrink inward by pulling the hinge group 44. At this time, the shrinking shell 45 gradually moves away from the movable clamping plate at the bottom, and then contacts the limiting effect on the end of the cloth body 13. Since the stress shell 42 and the shrinking shell 45 form a circular shell outside the support shaft 41 in the initial state, as the shrinking shell 45 shrinks, the stress shell 42 in the upper part of the support shaft 41 still maintains the overall support for the cloth body 13, while the stress shell 42 in the lower part of the support shaft 41 has a moving gap with the cloth body 13 due to its own shrinkage. In this way, the cloth end is quickly fixed and released, paving the way for the subsequent disassembly of the cloth roll, thereby greatly improving the automation of the equipment, reducing the need for manual intervention, and further improving production efficiency and convenience of operation. In summary, all of the above are the coordinated movements and operating principles between the partial structures. There are only two steps to dismantle the cloth body 13. First, remove the movable latch 24 from the support shaft 41. Secondly, separate the nut sleeve rod 23 from the movable latch 24, and simultaneously slide the three-dimensional bracket 21 as a whole to one side until it is offset from the support shaft 41. At this time, the cloth body 13 can be directly taken out from the side of the winding assembly 12 to complete the disassembly steps.

[0029] It should be noted that the hinge group 44 is composed of two mutually interlaced round rods, and the intersection of the round rods is movably connected through a hollow ball, and the size of the two ends of the hinge group 44 is half of the middle size; Specifically, the staggered round rod structure can increase the stability and load-bearing capacity of the hinge group 44, and through the movable connection of the hollow balls at the intersection of the round rods, the hinge group 44 can remain stable when subjected to external forces and pressures, reduce vibration and deformation, and improve the overall load-bearing capacity and working stability.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
