Technical Field

[0001] The present invention relates to the technical field of container bag stay cord cutting, and specifically to a cutting method for a container bag stay cord cutting device. Background Art

[0002] The cutting method of the container bag stay cord cutting device is a device used in the production or processing process of container bags, and its main function is to cut the stay cords of container bags.

[0003] The patent with the patent announcement number CN218711359U relates to an internal stay cord connecting and sewing device for a cubic container bag, including: an auxiliary material platform, a sewing platform, and a storage platform. A suspension vehicle is provided on the upper part of the auxiliary material platform, and the rear end of the suspension vehicle is fixedly connected to the two side brackets of the auxiliary material platform. A light sensor locator is provided on the auxiliary material platform. The sewing platform includes two symmetrically arranged large-span long-arm sewing machines and a pneumatic cutting knife. The pneumatic cutting knife is arranged at the rear side of the two large-span long-arm sewing machines. A manipulator is movably provided on the upper part of the storage platform, and the manipulator is movably connected to a slideway horizontally arranged on the upper part of the storage platform. A guiding mechanism is horizontally arranged at the front side of the storage platform.

The patent has a simple structure, is easy to use, has a low cost, and a high production efficiency.

[0004] In the above patent, the internal stay cord connecting, sewing and cutting device for the container bag changes the traditional process of sewing the main body of the cubic container bag and the internal stay cords, realizes the mechanization of component production and processing, and greatly improves the production efficiency of the internal stay cord cubic container bag. However, the existing hot cutting stay cord cutting technology is only applicable to single-piece stay cord cutting, and the tubular fabric needs to be slit and formed into a single-layer woven fabric roll before hot cutting. The number of cutting knives arranged is fixed, and after each stay cord is cut, the operator has to manually remove the stay cord piece. The processing speed is slow and the production efficiency is low. At the same time, when hot cutting the stay cord, the material is easily adhered to the cutting tool, which poses a safety hazard and affects the subsequent cutting effect. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cutting method for a container bag stay cord cutting device, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A container bag stay cord cutting device, comprising: a fabric reel mechanism, a guiding mechanism, a longitudinal cutting platform, a stay cord hole hot cutting - cord piece transverse cutting platform (hereinafter referred to as the operating table). A guiding mechanism is arranged on the right side of the fabric reel mechanism, a longitudinal cutting platform is arranged on the right side of the guiding mechanism, an operating table is arranged on the right side of the longitudinal cutting platform, a hot cutting device. The hot cutting device is arranged on the top of the operating table. The hot cutting device includes a support frame, an electric telescopic rod, a hot cutting knife, a through groove, a fixed frame, a sliding rod, a return spring, a pressing plate, a movable flat plate group, a rotating device, a clamping plate, a U-shaped partition, a numerical control chassis, a power traction device, a baffle and a transverse cutting knife. The fabric is guided by the guiding mechanism. The tubular fabric enters the longitudinal cutting platform and the excess fabric on both sides (scrap) is cut off by two longitudinal cutting knives arranged on both sides of the tabletop, and then forms a double-layer fabric of specified size and continues to move forward. After entering the operating table, the fabric stops moving forward according to the instruction of the numerical control chassis. At this time, the pressing plate is hidden in the hot cutting knife cavity and moves forward and backward together with the hot cutting knife. The support frame is fixedly installed on the top of the operating table, the electric telescopic rod is fixedly installed on the top of the support frame, the hot cutting knife is fixedly installed at the output end of the electric telescopic rod, the fixed frame is fixedly installed on the top inner wall of the hot cutting knife, the sliding rod is slidably installed on the inner wall of the fixed frame, the return spring is sleeved on the surface of the sliding rod, the pressing plate is fixedly installed at the bottom of the sliding rod, the movable flat plate group is arranged on the inner wall of the operating table, the rotating device is fixedly installed on the surface of the movable flat plate group, and there are guide rails that can move up and down and back and forth under the movable flat plate group. The clamping plate is fixedly installed at the output end of the rotating device, the U-shaped partition is fixedly installed on the surface of the movable flat plate group, the numerical control chassis is arranged on the surface of the operating table, the power traction device is arranged on the inner wall of the operating table, the baffle is arranged on the inner wall of the operating table, the transverse cutting knife is arranged on the inner wall of the operating table, and a cutting knife is arranged at the output end of the transverse cutting knife. The U-shaped partition will separate the two layers of fabric.

[0007] According to the above technical solution, the movable flat plate group is arranged on both sides of the inner wall of the operating table, and the clamping plates are arranged on the upper and lower sides of the U-shaped partition.

[0008] The present invention provides a cutting method for a container bag stay cord cutting device, and this device has the following beneficial effects:

[0009] 1. This device directly uses a circular woven tubular fabric roll on the machine. The fabric pulled out from the fabric roll is guided and spread multiple times by the guiding mechanism and then completes double-knife longitudinal splitting on the longitudinal cutting platform to form a "double-layer fabric" of specified size, and then enters the operating table. The clamping plates, hot cutting knives, and transverse cutting knives cooperate according to the instructions of the numerical control chassis as follows:

[0010] (1) "Clamp - pull": The numerical control chassis instructs the clamping plates on both sides of the fabric to clamp the fabric and slowly pull in opposite directions at the same time to tighten the fabric.

[0011] (2) "Cut - Kick - Lift": The CNC chassis instructs the hot cutting knife to press down on the specified "double - layer fabric" to complete the "cutting" action of the hole. At this time, the remaining pieces of the rib holes after hot cutting are in a "loosely connected" state with the rib - piece fabric, and there is also residual material left on the blade. The CNC chassis instructs that the sliding rod drives the pressure plate to quickly move downward, stretching the return spring and extending the pressure plate. The residual pieces of the rib holes are "kicked" into the through - slot on the operating table and fall into the collection box under the table. The sliding rod drives the pressure plate to return to the hot cutting knife cavity. Then the CNC chassis immediately instructs the clamping plate holding the double - layer fabric to lift upward, causing the fabric to move a short distance to the middle position of the vertical surface of the hot cutting knife and stop. This can make the cut edges of the double - layer fabric that are stuck together smoother under the heat melting of the knife body and separate the upper and lower layers of the fabric under the action of the U - shaped partition.

[0012] (3) "Rise - Fall - Cut": At this time, the hot cutting knife has completed the cutting task. The CNC chassis instructs the hot cutting knife to rise and reset. At the same time, the clamping plate holding the double - layer fabric falls to the operating table surface, and the two - side clamping plates loosen and reset. The double - layer fabric that has completed the hole cutting according to the instruction continues to move forward a section of the length of a rib fabric and stops. The horizontal cutting knife falls to cut off the double - layer fabric with holes, and the rib - piece cutting is completed.

[0013] 2. The above actions continue to repeat continuously, and two rib - pieces can be processed simultaneously each time. In this invention, through a series of actions of "Clamp - Pull", "Cut - Kick - Lift", and "Rise - Fall - Cut", it has been successfully achieved that: after the circular woven cylinder fabric roll forms the specified double - layer fabric through longitudinal double - splitting, it then passes through the operating table to complete - hot - pressing and cutting holes --- horizontally cutting rib - pieces. The whole set of actions is fully automated. Two rib - pieces can be cut simultaneously in one operation. The tool is not easily contaminated by residues, the product quality is stable, the safety performance is reliable, and the work efficiency is greatly improved. The distance between tools can be adjusted arbitrarily, the number of tools can be increased or decreased at will, and the density of the rib holes can be controlled, which is convenient for users to choose.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-6 , an embodiment of the present invention is: a container bag tension bar cutting device, including: a fabric reel mechanism 1, a guide mechanism 2 is arranged on the right side of the fabric reel mechanism 1, a longitudinal cutting platform 3 is arranged on the right side of the guide mechanism 2, an operating table 4 is arranged on the right side of the longitudinal cutting platform 3, a hot cutting device, the hot cutting device is arranged on the top of the operating table 4, and the hot cutting device includes a support frame 5, an electric telescopic rod 6, a hot cutting knife 7, a through groove 8,; a fixed frame 9, a slide bar 10, a return spring 11, a pressing plate 12, a movable flat plate group 13, a rotating device 14, a clamping plate 15, a U-shaped partition 16, a numerical control chassis 17, a power traction device 18, a baffle 19 and a transverse cutting knife 20; the support frame 5 is fixedly installed on the top of the operating table 4, the electric telescopic rod 6 is fixedly installed on the top of the support frame 5, the hot cutting knife 7 is fixedly installed at the output end of the electric telescopic rod 6, the fixed frame 9 is fixedly installed on the top inner wall of the hot cutting knife 7, the slide bar 10 is slidably installed on the inner wall of the fixed frame 9, the return spring 11 is sleeved on the surface of the slide bar 10, the pressing plate 12 is fixedly installed at the bottom of the slide bar 10, and the pressing plate 12 is hidden in the cavity of the hot cutting knife 7 when not working. The movable flat plate group 13 is arranged on the inner wall of the operating table 4, the rotating device 14 is fixedly installed on the surface of the movable flat plate group 13, a guide rail that can move up and down and back and forth is arranged under the movable flat plate group 13, the clamping plate 15 is fixedly installed at the output end of the rotating device 14, the U-shaped partition 16 is fixedly installed on the surface of the movable flat plate group 13, the numerical control chassis 17 is arranged on the surface of the operating table 4, the power traction device 18 is arranged on the inner wall of the operating table 4, the baffle 19 is arranged on the inner wall of the operating table 4, the transverse cutting knife 20 is arranged on the inner wall of the operating table 4, and a cutting tool is arranged at the output end of the transverse cutting knife 20.

[0023] The mobile flat plate assembly 13 is arranged on both sides of the inner wall of the operating table 4, and the clamping plates 15 are arranged on the upper and lower sides of the U-shaped partition 16.

[0024] The cutting method of the container bag stay cord cutting device includes the following steps:

[0025] Step 1: The clamping plates on both sides of the fabric are clamped by the instructions of the numerical control chassis, and at the same time, they are slowly pulled in opposite directions to make the fabric taut.

[0026] Step 2: The hot cutting knife is pressed down by the instructions of the numerical control chassis to complete the "cutting" action of the holes on the "double-layer fabric" of the specification. At this time, the residual pieces of the stay cord holes after hot cutting are in a "connected but separated" state with the stay cord fabric, and there is also residual material left on the blade. The numerical control chassis instructs the sliding rod to drive the pressure plate to quickly move downward, the reset spring stretches, and the pressure plate extends. The residual pieces of the stay cord holes are "kicked" into the through groove on the operating table and fall into the collection box under the tabletop. The sliding rod drives the pressure plate to reset and return to the hot cutting knife cavity. Immediately afterwards, the numerical control chassis instructs the clamping plates holding the double-layer fabric to be lifted upward, so that the fabric moves a short distance and stops at the middle position of the vertical surface of the hot cutting knife. This can make the cut edges of the double-layer fabric stick together smoother under the heat melting of the knife body and separate the upper and lower layers of the fabric under the action of the U-shaped partition.

[0027] Step 3: At this time, the hot cutting knife has completed the cutting task. The numerical control chassis instructs the hot cutting knife to rise and reset. At the same time, the clamping plates holding the double-layer fabric fall to the operating tabletop, and the clamping plates on both sides are loosened and reset. The double-layer fabric that has completed the hole cutting according to the instructions continues to move forward for a section of the length of a stay cord fabric and stops. The transverse cutting knife drops to cut off the double-layer fabric with holes, and the cutting of the stay cord pieces is completed. The above actions continue to repeat continuously, and two stay cords can be processed simultaneously each time.

[0028] During the operation of this embodiment: The round woven tubular fabric roll is directly put on the machine through the feeding fabric reel mechanism 1. After being guided and spread by the guiding mechanism 2 for many times, it completes the double-knife longitudinal splitting on the longitudinal cutting platform 3 to form the "double-layer fabric" of the specification, and then enters the operating table 4. Then, through a series of actions of "clamp - pull", "cut - kick - lift", and "lift - lower - cut", the cutting of the stay cords is realized.

[0029] Please refer to Figures 1-6 , Another embodiment of the present invention is: The cutting method of the container bag stay cord cutting device includes the following steps:

[0030] (1) "Clamp - pull": The numerical control chassis 17 instructs the clamping plates 15 on both sides of the fabric to clamp the fabric, and at the same time, they are slowly pulled in opposite directions to make the fabric taut.

[0031] (2) "Cut - Kick - Lift": The CNC chassis 17 commands the hot - cutting knife 7 to press down on the specified "double - layer fabric" to complete the "cutting" action of the holes. At this time, the remaining pieces of the rib holes after hot - cutting are in a "loosely connected" state with the rib - piece fabric, and there is also residual material left on the blade. The CNC chassis 17 commands that the slide bar 10 drives the pressure plate 12 to quickly move downward, stretching the return spring 11 and extending the pressure plate 12. The remaining pieces of the rib holes are "kicked" into the through - slot 7 on the operation table 4 and fall into the collection box under the tabletop. The slide bar 10 drives the pressure plate 12 to reset and return to the cavity of the hot - cutting knife 7. Then the CNC chassis 17 immediately commands the clamp 15 holding the double - layer fabric to lift upward, causing the fabric to move a short distance to the middle position of the vertical surface of the hot - cutting knife 7 and stop. This can make the cut edges of the double - layer fabric that are stuck together smoother under the heat melting of the knife body and separate the upper and lower layers of the fabric under the action of the U - shaped partition 16.

[0032] (3) "Lift - Drop - Cut": At this time, the hot - cutting knife 7 has completed the cutting task. The CNC chassis 17 commands the hot - cutting knife 7 to lift and reset. At the same time, the clamp 15 holding the double - layer fabric drops to the surface of the operation table 4, and the two - side clamps 15 loosen and reset. The double - layer fabric that has completed the hole cutting continues to move forward a section of the length of a rib fabric and stops according to the command. The transverse cutting knife 20 drops to cut off the double - layer fabric with holes, and the rib - piece cutting is completed. The above actions continue to repeat continuously, and two rib - pieces can be processed simultaneously each time.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
