Description

Technical Field

[0001] The present invention relates to the technical field of woven bag processing, and particularly to a laser cutting machine for processing degradable woven bags. Background Art

[0002] A degradable woven bag is a packaging bag made of degradable materials. Such materials can decompose into harmless substances through physical, chemical, or biological actions within a specific time in the natural environment, effectively reducing the environmental pollution problems caused by traditional woven bags. Its production raw materials usually include degradable high molecular polymers, such as polylactic acid (PLA), polybutylene adipate / terephthalate (PBAT), etc. These raw materials endow the woven bag with good flexibility and strength, enabling it to meet packaging requirements while possessing environmental protection characteristics. Degradable woven bags are widely used in multiple fields such as agriculture, food, and chemical industry for containing various items, playing a key role in promoting the sustainable development of the packaging industry. When processing degradable woven bags, it is usually necessary to cut the rolled woven fabric for subsequent processes such as printing and stitching. With a laser beam of high energy density, laser cutting technology can quickly melt or vaporize the woven fabric, achieving a cutting effect with high precision and narrow cut seams, and can be applied to the cutting of woven fabric. In an integrated production line, heat treatment can be used as a pre-process for laser cutting. For example, after locally heating the material with an infrared heater and then performing laser cutting, the processing efficiency can be significantly improved and thermal damage can be reduced. However, the application of this heat treatment process varies in the cutting and processing of woven fabric.

[0003] The existing technology still has the following problems:

[0004] 1. Currently, when cutting woven fabric, one end of the woven fabric to be cut is usually directly placed on the cutting table, and the whole woven fabric is in a relatively loose state. In this loose state, the tension uniformity of the woven fabric is extremely poor. During the cutting process, the woven fabric is extremely prone to displacement and shaking, and it is difficult for the cutting equipment to accurately execute the cutting according to the preset path. Frequent cutting size deviations occur, and it is difficult to ensure the neatness of the cutting edge, seriously affecting the cutting quality.

[0005] 2. Currently, before cutting the woven fabric into pieces, the woven fabric is not preheated. This results in the woven fabric absorbing laser energy and rapidly heating up when the laser cutting head cuts the woven fabric. If the initial temperature of the woven fabric is too low and the temperature gradient change is too large, thermal stress is easily generated, which may then lead to thermal damage phenomena such as deformation and embrittlement of the woven fabric, affecting the quality and performance of the subsequent woven bag. Summary of the Invention

[0022] The beneficial effects of the present invention:

[0023] 1. The side plate is driven to move by the electric cylinder, and the third oblique guide groove on the side plate guides the guide block, so that the horizontal bar drives the push-flat roller to move downward and press against the upper surface of the woven cloth. The push-flat roller always keeps a state of pressing against the woven cloth through the sliding cooperation between the vertical sliding column and the horizontal bar and the elastic compression of the first elastic member, and rolls on the woven cloth, which can adjust some local slack parts, thereby improving the uniformity of tension. In this way, the woven cloth can maintain a more stable shape during cutting, which is conducive to improving the cutting quality.

[0024] 2. Through the setting of intelligent heat treatment components, before cutting, the inside of the preheating box is heated by infrared heaters to heat the woven fabric inside. Preheating the woven fabric in advance by infrared heaters can reduce the temperature gradient during cutting, make the woven fabric heated more evenly, reduce the generation of thermal stress, and effectively improve the cutting quality of the laser cutting head and reduce thermal damage.

[0025] 3. When the woven cloth is cut, the electric cylinder continues to extend, and the second guide roller enters the fourth inclined guide groove. Under its guiding action, the second guide roller drives the support plate to rotate along the rotation point connected to the support plate, so that the end of the support plate away from the support plate flips downward, so that the cut woven cloth on the support plate will automatically slide down under the action of its own gravity, completing the unloading process and improving work efficiency.

[0026] 4. By driving the cutting component and the flattening component to move through the driving component, the laser cutting head can avoid the flattening component, and after avoiding, the laser cutting head can be reset to the cutting height to meet the cutting needs.

The upper pressing roller 4 and the lower roller 5 are respectively tightly pressed against the upper and lower surfaces of the woven cloth, thereby increasing the friction between the woven cloth and the upper pressing roller 4 and the lower roller 5.

[0043] Reference Figures 1 to 7 The driving component 6 includes an electric cylinder 61, which is electrically connected to the external control system. The electric cylinder 61 is fixedly connected to the wall of the main frame 1. The telescopic end of the electric cylinder 61 is fixedly connected to a push plate 62, and both ends of the push plate 62 are fixedly connected to side plates 63. The side plates 63 are horizontally penetrated by a first oblique guide groove 64, a first horizontal guide groove 65, a second oblique guide groove 66, a second horizontal guide groove 67, a third oblique guide groove 68, a third horizontal guide groove 69 and a fourth oblique guide groove 610; the top of the first oblique guide groove 64 is connected to one end of the first horizontal guide groove 65, the other end of the first horizontal guide groove 65 is connected to the top of the second oblique guide groove 66, the bottom end of the second oblique guide groove 66 is connected to one end of the second horizontal guide groove 67, the first oblique guide groove 64 and the second oblique guide groove 66 are symmetrically arranged, and one end of the third horizontal guide groove 69 is connected to the top of the fourth oblique guide groove 610.

[0044] Specifically, when the electric cylinder 61 is activated, its telescopic end extends or retracts, driving the push plate 62 to move. The side plates 63 at both ends of the push plate 62 will move synchronously, thereby driving the first inclined guide groove 64, the first horizontal guide groove 65, the second inclined guide groove 66, the second horizontal guide groove 67, the third inclined guide groove 68, the third horizontal guide groove 69, and the fourth inclined guide groove 610.

Through the guiding effect, the movement trajectories and positions of the cutting component 7, the leveling component 8, and the unloading component 9 at different stages are precisely controlled, realizing the orderly progress of the cutting, leveling, and unloading actions.

[0045] Embodiment 2. Refer to Figures 1 to 9 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the cutting component 7 includes a mounting frame 71. The bottom end of the mounting frame 71 is fixedly connected to the wall of the main body bracket 1. Four vertical sliding rods 72 are symmetrically and fixedly connected to the wall of the mounting frame 71. A cross frame 73 is longitudinally penetrated and slidably sleeved on the four vertical sliding rods 72. A sliding block 75 is slidably connected to the inside of the cross frame 73. A laser cutting head 76 is fixedly installed at the lower part of the sliding block 75. The laser cutting head 76 is connected to an external control system. A driving motor 74 is fixedly installed on the wall of the cross frame 73. The driving motor 74 is electrically connected to the external control system. A horizontal threaded rod 77 is horizontally penetrated and threadedly connected to the sliding block 75. One end of the horizontal threaded rod 77 is rotatably connected to the inside of the cross frame 73. The other end of the horizontal threaded rod 77 passes through the wall of the cross frame 73 and is fixedly connected to the rotating end of the driving motor 74. Two fixing rods 78 are symmetrically and fixedly connected to both sides of the bottom of the cross frame 73. The bottom end of the fixing rod 78 is rotatably connected to a first guide roller 79; the first guide roller 79 is arranged in the first inclined guide groove 64. The first inclined guide groove 64, the first horizontal guide groove 65, the second inclined guide groove 66, and the second horizontal guide groove 67 are all adapted to the first guide roller 79.

[0046] Specifically, when the telescopic end of the electric cylinder 61 extends to drive the side plate 63 to move, the first inclined guide groove 64 on the side plate 63 guides the first guide roller 79, causing the first guide roller 79 to move upward. The upward movement of the first guide roller 79 drives the fixing rod 78 and the cross frame 73 to slide upward along the vertical sliding rod 72, thereby causing the laser cutting head 76 installed at the lower part of the sliding block 75 to move upward. When the first guide roller 79 enters the second inclined guide groove 66, it moves downward, causing the laser cutting head 76 to descend to the initial cutting height. The driving motor 74 is started to drive the horizontal threaded rod 77 to rotate. Under the action of the threaded connection, the sliding block 75 slides along the cross frame 73, thereby driving the laser cutting head 76 to perform a linear motion. The laser cutting head 76 outputs a laser beam to cut the woven fabric; the remaining structures are the same as those in Embodiment 1.

[0047] Embodiment 3. Refer toFigures 1 to 11 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the leveling member 8 includes fixed bars 81. There are two fixed bars 81 symmetrically arranged. The bottom ends of the fixed bars 81 are fixedly connected to the wall of the main body bracket 1. A support plate 82 is fixedly connected to the tops of the two fixed bars 81 together. Above the support plate 82, there is a cross bar 83. Two lifting sliding sleeves 84 are symmetrically and fixedly connected to both ends of the cross bar 83. A guiding block 85 is fixedly connected to the wall of the lifting sliding sleeve 84. A plurality of vertical sliding columns 86 are longitudinally and slidably connected through the cross bar 83. A mounting seat 88 is fixedly connected to the bottoms of the plurality of vertical sliding columns 86 together. A leveling rotating roller 89 is rotatably connected to the lower part of the mounting seat 88. A first elastic member 87 is sleeved on the vertical sliding column 86. The top end of the first elastic member 87 is fixedly connected to the bottom of the cross bar 83, and the bottom end of the first elastic member 87 is fixedly connected to the top of the mounting seat 88. The first elastic member 87 can be a spring. The guiding block 85 is arranged in the third inclined guiding groove 68, and the guiding block 85 is adapted to the third inclined guiding groove 68.

[0048] Specifically, when the telescopic end of the electric cylinder 61 extends to drive the side plate 63 to move, the third inclined guiding groove 68 on the side plate 63 guides the guiding block 85, causing the guiding block 85 to move downward, and then driving the lifting sliding sleeve 84 and the cross bar 83 to move downward. During the downward movement of the cross bar 83, the leveling rotating roller 89 presses on the upper surface of the woven fabric. Through the sliding cooperation of the vertical sliding column 86 on the cross bar 83 and the elastic compression of the first elastic member 87, the leveling rotating roller 89 always maintains a state of pressing against the woven fabric and rolls on the woven fabric, making the woven fabric flatter, providing a flatter woven fabric for the cutting process, reducing the slack of the woven fabric at the same time, and improving the cutting accuracy. The rest of the structure is the same as that of the second embodiment.

[0049] Embodiment Four, referring to Figures 1 to 12 This is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that a discharging member 9 is further arranged on one side of the main body bracket 1. The discharging member 9 includes a support plate 91. The support plate 91 is rotatably connected to one side of the support plate 82. A vertical guiding rod 97 is longitudinally and slidably connected through the lifting sliding sleeve 84. A cross bar 95 is fixedly connected to one side of the bottom end of the vertical guiding rod 97. Guiding strips 92 corresponding to the cross bars 95 one by one are fixedly connected to the wall of the main body bracket 1. The cross bar 95 is horizontally and slidably connected through the corresponding guiding strip 92. A second elastic member 96 is sleeved on the cross bar 95. One end of the second elastic member 96 is fixedly connected to the wall of the guiding strip 92, and the other end of the second elastic member 96 is fixedly connected to the wall of the vertical guiding rod 97. The second elastic member 96 can be a spring. Two fixing blocks 93 are symmetrically and fixedly connected to the bottom of the support plate 91. A second guiding roller 94 is rotatably connected to the lower part of the fixing block 93. The second guiding roller 94 is arranged in the third horizontal guiding groove 69, and the second guiding roller 94 is adapted to the third horizontal guiding groove 69.

[0050] Specifically, when the telescopic end of the electric cylinder 61 extends to drive the side plate 63 to move, after the guide block 85 moves to the bottom end of the third inclined guide groove 68, the side plate 63 continues to move to push the guide block 85, thereby driving the lifting sliding sleeve 84 to move. The lifting sliding sleeve 84 pushes the vertical guide rod 97 to move, so that the second elastic member 96 is elastically compressed. The vertical guide rod 97 drives the cross bar 95 to slide on the guide strip 92, and the flattening roller 89 moves from the support plate 82 to the support plate 91, always pressing on the woven fabric to keep the woven fabric flat. After the woven fabric is cut, the electric cylinder 61 continues to extend, and the second guide roller 94 enters the fourth inclined guide groove 610. Under its guiding action, the second guide roller 94 drives the support plate 91 to rotate along the rotation point connected to the support plate 82, so that the end of the support plate 91 away from the support plate 82 flips downward, and the cut woven fabric on the support plate 91 automatically slides into the collection box below to complete the unloading action.

[0051] Referring to Figure 2 , an intelligent heat treatment component 10 is further installed on the main body bracket 1. The intelligent heat treatment component 10 includes a preheating box 101, and the preheating box 101 is fixedly connected to the wall of the main body bracket 1. An infrared heater 102 is fixedly installed inside the preheating box 101. The infrared heater 102 is electrically connected to an external control system. Through holes 103 for the woven fabric to pass through are horizontally penetrated through both sides of the preheating box 101.

[0052] Specifically, before cutting the woven fabric, the infrared heater 102 is started. The infrared heater 102 generates heat during operation, so that the temperature inside the preheating box 101 rises. When the woven fabric passes through the preheating box 101 through the through hole 103, it is heated and its temperature rises. The initial temperature of the woven fabric is increased, the temperature gradient of the woven fabric during cutting by the laser cutting head 76 is reduced, the woven fabric is heated more evenly during the cutting process, the generation of thermal stress is reduced, and further thermal damage is reduced, improving the cutting quality; the remaining structure is the same as that of the third embodiment.

[0053] Referring to Figures 1 to 12 , the working principle of the laser cutting machine for processing degradable woven bags in the present invention is as follows:

[0054] Wind the degradable woven fabric used for processing degradable woven bags around the winding roller 2, and pass one end of the woven fabric through the fabric passing port 103 first, and then pass through between the upper pressing roller 4 and the lower supporting roller 5. The upper pressing roller 4 and the lower supporting roller 5 are respectively abutted against the upper surface and the lower surface of the woven fabric. Start the main motor 3, drive the lower supporting roller 5 to rotate through the main motor 3. Under the action of friction and the rotation cooperation of the upper pressing roller 4, the lower supporting roller 5 rotates to drive the woven fabric to move towards the direction close to the support plate 91, and then drive the winding roller 2 to rotate to gradually release the woven fabric until one end of the woven fabric extends onto the support plate 91 to meet the required cutting length and then stop. Start the infrared heater 102 in the intelligent heat treatment component 10. Heat the inside of the preheating box 101 through the infrared heater 102, and the woven fabric located in the preheating box 101 is heated to improve the cutting quality of the subsequent laser cutting head 76 and reduce the thermal damage of the subsequent cutting. Because when the laser cutting head 76 performs laser cutting, the material will quickly heat up due to absorbing laser energy. If the initial temperature of the material is too low and the temperature gradient change is too large, it is easy to generate thermal stress, which will lead to thermal damage phenomena such as material deformation and embrittlement. Preheating the woven fabric in advance through the infrared heater 102 can reduce the temperature gradient during cutting, make the material heat more evenly, and reduce the generation of thermal stress, thereby effectively reducing thermal damage; then start the electric cylinder 61. The telescopic end of the electric cylinder 61 extends to drive the push plate 62 to move, and the push plate 62 drives the two side plates 63 to move synchronously. When the side plates 63 move forward, the first inclined guide groove 64 guides the first guide roller 79 to move upward, and at the same time the third inclined guide groove 68 guides the guide block 85 to move downward, and the third horizontal guide groove 69 guides the second guide roller 94 to keep it stationary in the horizontal position. The upward movement of the first guide roller 79 drives the fixing rod 78 to move upward, and the fixing rod 78 drives the cross frame 73 to slide upward along the vertical slide rod 72. The cross frame 73 drives the sliding block 75 to make the laser cutting head 76 move upward. At the same time, the downward movement of the guide block 85 drives the lifting slide sleeve 84 to make the cross bar 83 move downward, and then drives the flattening roller 89 to move downward and press against the upper surface of the woven fabric located on the support plate 82. And through the sliding cooperation of the vertical slide column 86 on the cross bar 83, and at the same time the first elastic member 87 is elastically compressed, so that the flattening roller 89 remains pressed against the upper surface of the woven fabric. At this time, the guide block 85 just moves from the top end of the third inclined guide groove 68 to the bottom end of the third inclined guide groove 68, and at this time the laser cutting head 76 moves above the cross bar 83 and will not interfere with the forward movement of the flattening component 8;During the movement of the guide block 85 from the top end of the third oblique guide groove 68 to the bottom end of the third oblique guide groove 68, the pressure of the external force on the second elastic member 96 is less than the resistance of the second elastic member 96 itself, and the second elastic member 96 does not produce elastic deformation. At this time, the cross bar 95 does not slide. When the guide block 85 moves to the bottom end of the third oblique guide groove 68, the side plate 63 continues to move, pushing the guide block 85 to move the push-flattening roller 89, so that the push-flattening roller 89 rolls on the upper surface of the woven cloth, so that the woven cloth remains in a relatively flat state; then the first guide roller 79 continues to move in the first horizontal guide groove 65, so that the laser cutting head 76 remains at the current height until the push-flattening roller 89 is pushed to the bottom end of the third oblique guide groove 68. After the flat roller 89 moves from under the laser cutting head 76 and staggers with the cutting component 7, the laser cutting head 76 no longer interferes with the movement of the flattening component 8. At this time, the first guide roller 79 enters the second oblique guide groove 66 and moves downward, so that the laser cutting head 76 moves downward to the initial cutting height. Then, the first guide roller 79 moves from the second oblique guide groove 66 to the second horizontal guide groove 67. The laser cutting head 76 remains at the current cutting height and no longer moves. The telescopic end of the control electric cylinder 61 stops extending.
