Description

Technical Field

[0001] This invention relates to the field of woven bag processing technology, and in particular to a laser cutting machine for processing biodegradable woven bags. Background Technology

[0002] Biodegradable woven bags are packaging bags made from biodegradable materials. These materials can decompose into harmless substances in the natural environment within a certain time through physical, chemical, or biological processes, effectively reducing the environmental pollution problems caused by traditional woven bags. Their raw materials typically include biodegradable polymers such as polylactic acid (PLA) and polybutylene adipate / terephthalate (PBAT). These materials give the woven bags good flexibility and strength, enabling them to meet packaging requirements while possessing environmentally friendly characteristics. Biodegradable woven bags are widely used in agriculture, food, chemicals, and other fields to hold various items, playing a key role in promoting the sustainable development of the packaging industry. During the processing of biodegradable woven bags, the rolled woven fabric usually needs to be cut for subsequent printing, sewing, and other processes. Laser cutting technology, with its high-energy-density laser beam, can quickly melt or vaporize the woven fabric, achieving high-precision, narrow-kerf cutting effects. It can be applied to the cutting of woven fabric in integrated production lines.

[0003] A search revealed a Chinese invention patent, CN120347398A, which discloses a laser cutting machine for processing biodegradable woven bags. The machine includes a main support frame with an upper pressure roller and a lower support roller rotatably mounted on its wall. A main motor is installed on the frame wall, and one end of the lower support roller passes through the frame wall and connects to the rotating end of the main motor. A take-up roller for winding the woven fabric is rotatably mounted on the other side of the main support frame. A drive component, a cutting component, and a flattening component are located on one side of the main support frame. An electric cylinder drives a side plate to move, and a third oblique guide groove on the side plate guides a guide block, causing a horizontal bar to drive the flattening roller downwards and press it against the surface of the woven fabric. This allows for the adjustment of some loose parts, improving cutting quality. Furthermore, during cutting, the flattening roller remains pressed against the woven fabric, reducing fabric displacement during the cutting process. Intelligent heat treatment components further ensure cutting quality.

[0004] Existing equipment has low efficiency in replacing take-up rollers and insufficient stability. During the fabric conveying process, wrinkles, deviations, or uneven speeds are prone to occur, affecting cutting accuracy. When cutting woven bags, displacement is easily caused by vibration or tension, resulting in skewed cuts. Furthermore, biodegradable materials are sensitive to heat, and traditional cutting methods can easily lead to the deterioration of material properties.

[0005] Therefore, the existing laser cutting machine for processing biodegradable woven bags cannot meet the needs of actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the Invention

[0020] The present invention has the following beneficial effects:

[0021] 1. This invention utilizes an installation structure mounted on a base plate to house the feeding structure, positioning structure, heating structure, extrusion structure, and cutting structure during use. This facilitates the processing of woven straps. The feeding structure on the installation structure allows for the accumulation of processed materials, facilitating subsequent material handling. The positioning structure on the installation structure clamps and presses the fabric, ensuring its stable placement above the heating structure. A discharge motor on one side of the installation structure ensures continuous and uniform feeding of the woven strap. The heating structure on the installation structure, controlled by a heating control module, heats the cutting base plate, raising the temperature of the woven bag surface and reducing heat loss during subsequent laser cutting. This helps improve cutting quality, reduces fabric deformation and melt marks caused by an excessively large heat-affected zone, and ensures the processing quality of biodegradable woven bags.

[0022] 2. This invention utilizes an extrusion structure on the mounting structure. During use, the downward pressure of the inner extrusion rod and the speed-limiting effect of the speed-limiting structure stably clamp and fix the fabric bag during processing, preventing displacement and wrinkling of the fabric during cutting. This further ensures the accuracy and stability of the cutting, effectively improving the product qualification rate. The speed-limiting structure on the extrusion structure limits the rotational speed of the speed-limiting gear through the extension and retraction of the telescopic inner rod and the speed-limiting spring. Since the speed-limiting gear is fixedly connected to the extrusion roller, the rotational speed of the extrusion roller is also limited. The cutting structure on the mounting structure allows the cutting connecting rod to slide back and forth along the inner cavity of the sliding frame, thereby driving the laser cutting blade to move back and forth, achieving rapid cutting of the fabric and improving production efficiency. Moreover, compared to traditional cutting methods, this cutting method can more precisely control the cutting position and shape, meeting the processing needs of biodegradable woven bags of different specifications. Through the placement structure on the bottom plate, the winding roller is double-fixed by the back-and-forth sliding of connecting block one and connecting block two during use, avoiding the offset problem caused by traditional single-point fixing, ensuring the stability of the winding structure during high-speed operation, and reducing the risk of fabric displacement caused by vibration or inertia. Through the connecting structure on the placement structure, the connecting block two slides backward and interlocks with the front locking groove during use, which can play a stable fixing role for the winding structure, preventing it from shaking or shifting during operation, and ensuring the stability of subsequent fabric conveying and cutting.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A placement structure 9 is fixedly connected to the upper end face of the base plate 1 on the side of the woven bag feed. A connecting structure 10 is provided on one side of the inner cavity of the placement structure 9. A winding structure 11 is provided between the connecting structure 10 and the side wall of the inner cavity of the placement structure 9.

[0036] The mounting structure 2 includes a mounting frame 21 fixedly connected to the middle of the upper end face of the base plate 1. The mounting frame 21 has mounting grooves 22 symmetrically opened on the front and rear sides of the inner cavity along the center. The mounting plate 23 is fixedly connected to the upper end face of the mounting frame 21. The feeding structure 3 is fixedly connected to the side of the mounting frame 21 near the output of the woven bag. The inner cavity of the mounting groove 22 is provided with a positioning structure 4. Through the mounting structure 2 on the base plate 1, the feeding structure 3, positioning structure 4, heating structure 5, extrusion structure 6 and cutting structure 8 can be installed and placed during use, thereby facilitating the processing of the woven belt by personnel.

[0037] Furthermore, the feeding structure 3 includes a feeding plate 31 fixedly connected to the left end face of the mounting frame 21. Supporting diagonal rods 32 are evenly fixedly connected between the lower end face of the feeding plate 31 and the mounting frame 21. A connecting crossbar 33 is fixedly connected between the two opposing supporting diagonal rods 32. The horizontal height of the feeding plate 31 is the same as that of the heating structure 5. Through the feeding structure 3 on the mounting structure 2, the processed materials are stacked and placed during use, which facilitates the subsequent processing of the materials by personnel.

[0038] Furthermore, the positioning structure 4 includes a positioning slide rod 41 fixedly connected to the inner cavity of the mounting groove 22. A slider 42 is slidably connected to the outer surface of the positioning slide rod 41. A positioning roller 43 is rotatably connected between the two sliders 42. A positioning spring is transmitted between the two sliders 42. The positioning spring is movably sleeved on the outer surface of the positioning slide rod 41. A feeding motor is fixedly connected to one side of the front end face of the mounting frame 21. The rotating shaft of the front end face of the positioning roller 43 on the lower right side passes through the mounting frame 21 and is fixedly connected to the feeding motor. Through the positioning structure 4 on the mounting structure 2, the fabric is pressed down and clamped during use, so that the fabric can be stably placed above the heating structure 5. Then, through the discharge motor set on one side of the mounting structure 2, the woven belt side is continuously discharged at a uniform speed.

[0039] Furthermore, the heating structure 5 includes a cutting base plate 51 fixedly connected to the inner cavity of the mounting frame 21 between two mounting slots 22. The inner cavity of the cutting base plate 51 has a placement slot 52, and heating elements 53 are uniformly fixedly connected to the lower end face of the placement slot 52. A heating control module 54 is fixedly connected to the lower end face of the cutting base plate 51. The heating elements 53 penetrate the cutting base plate 51 and are electrically connected to the heating control module 54. The horizontal height of the cutting base plate 51 is the same as that of the feed plate 31. Through the heating structure 5 on the mounting structure 2, the heating control module 54 controls the heating elements 53 to start, heating the cutting base plate 51 and raising the temperature of the woven bag on the surface of the cutting base plate 51, thereby reducing heat loss during subsequent laser cutting. This helps improve cutting quality, reduce fabric deformation and melt marks caused by an excessively large heat-affected zone, and ensure the processing quality of the biodegradable woven bags.

[0040] Furthermore, the extrusion structure 6 includes a sliding sleeve 61 symmetrically fixedly connected to the middle of the lower end face of the mounting plate 23. A compression spring 62 is fixedly connected to the upper end face of the inner cavity of the sliding sleeve 61, and an inner compression rod 63 is slidably connected to the inner cavity of the sliding sleeve 61. The lower end face of the compression spring 62 is fixedly connected to the inner compression rod 63. An extrusion roller 64 is rotatably connected between the two inner compression rods 63. A speed limiting structure 7 is provided at the lower rear end of the rear inner compression rod 63. Through the extrusion structure 6 on the mounting structure 2, the extrusion rod 63 presses down and the speed limiting structure 7 limits the speed, thus stably clamping and fixing the fabric bag during processing. This prevents the fabric from shifting or wrinkling during the cutting process, further ensuring the accuracy and stability of the cutting and effectively improving the product qualification rate.

[0041] Furthermore, the speed limiting structure 7 includes a speed limiting gear 71 rotatably connected to the rear end face of the rear extrusion inner rod 63. The extrusion inner rod 63 is fixedly connected to the upper part of the speed limiting gear 71 by a telescopic sleeve 72. The telescopic inner rod 73 is slidably connected to the inner cavity of the telescopic sleeve 72. A speed limiting spring is transmitted between the inner cavity of the telescopic sleeve 72 and the telescopic inner rod 73. The lower end face of the telescopic inner rod 73 matches the speed limiting gear 71. The rear end face of the extrusion roller 64 has a rotating shaft that passes through the extrusion inner rod 63 and is fixedly connected to the speed limiting gear 71. Through the speed limiting structure 7 on the extrusion structure 6, the speed of the speed limiting gear 71 is limited by the extension and retraction of the telescopic inner rod 73 and the speed limiting spring during use. Since the speed limiting gear 71 is fixedly connected to the extrusion roller 64, the speed of the extrusion roller 64 is limited.

[0042] Furthermore, the cutting structure 8 includes a cutting motor 81 fixedly connected to one side of the front end of the mounting frame 21. A sliding frame 82 is fixedly connected to the lower end face of the mounting plate 23 on one side of the extrusion structure 6. A threaded connection is rotatably connected to the inner cavity of the sliding frame 82. A cutting connecting rod 83 is slidably connected to the inner cavity of the sliding frame 82. A threaded rod in the inner cavity of the sliding frame 82 passes through the cutting connecting rod 83 and is threadedly connected. The front end face of the threaded rod passes through the mounting frame 21 and is fixedly connected to the output end of the cutting motor 81. A laser cutter is fixedly connected to the lower end face of the cutting connecting rod 83. Through the cutting structure 8 on the mounting structure 2, the cutting connecting rod 83 slides back and forth along the inner cavity of the sliding frame 82 during use, thereby driving the laser cutting blade to move back and forth, realizing rapid cutting of the fabric and improving production efficiency. Moreover, compared with traditional cutting methods, this cutting method can more accurately control the cutting position and shape, meeting the processing needs of biodegradable woven bags of different specifications.

[0043] Furthermore, the placement structure 9 includes a placement plate 91 fixedly connected to the rear part of the upper end face of the base plate 1 located on the side of the woven bag feeding, a connecting block 92 rotatably connected to the upper part of the front end face of the placement plate 91, and an adjustment structure 93 fixedly connected to the upper end of the base plate 1 located in front of the placement plate 91.

[0044] The adjustment structure 93 includes an adjustment plate 931 fixedly connected to the upper end face of the base plate 1 at the front of the placement plate 91. The rear end face of the adjustment plate 931 is provided with an adjustment groove 932. A limit ring 933 is fixedly connected to the outer edge of the adjustment groove 932 at the rear end face of the adjustment plate 931. A connecting structure 10 is provided in the inner cavity of the adjustment groove 932. Through the placement structure 9 on the base plate 1, the winding roller is double-fixed by the back-and-forth sliding of the connecting block 92 and the connecting block 102 during use. This avoids the offset problem caused by traditional single-point fixing, ensures the stability of the winding structure during high-speed operation, and reduces the risk of fabric displacement caused by vibration or inertia.

[0045] Furthermore, the connecting structure 10 includes a connecting handle 101 slidably connected to the inner cavity of the adjusting groove 932. A connecting block 2 102 is rotatably connected to the rear end face of the connecting handle 101. A limiting groove 103 matching the limiting ring 933 is opened on the front end face of the connecting block 2 102. A connecting spring is driven between the connecting block 2 102 and the front end face of the inner cavity of the adjusting groove 932. A winding structure 11 is provided between the connecting block 2 102 and the connecting block 1 92. Through the connecting structure 10 on the placement structure 9, the connecting block 2 102 slides backward and engages with the front engaging groove 112 during use, which can play a stable fixing role for the winding structure 11, preventing it from shaking or shifting during operation, and ensuring the stability of subsequent fabric conveying and cutting.

[0046] Furthermore, the winding structure 11 includes a winding roller 111 placed between the second connecting block 102 and the first connecting block 92. The front and rear end faces of the winding roller 111 are respectively provided with snap-fit ​​grooves 112 that match the first connecting block 92 and the second connecting block 102.

[0047] Working principle:

[0048] During operation, pulling the connecting handle feed 101 causes the connecting block feed 102 to slide forward. At this time, the connecting block feed 102 engages with the inner cavity of the adjusting groove feed 932. Simultaneously, the connecting spring retracts. The operator then places the winding structure feed 11, containing the biodegradable woven fabric roll for biodegradable bag processing, between the placement plate feed 91 and the adjusting structure feed 93. Simultaneously, the rear engaging groove feed 112 of the winding roller feed 111 engages with the connecting block feed 92, allowing one end of the woven fabric to pass through the positioning structure feed 4. The woven fabric is then placed above the cutting base plate feed 51.

[0049] Then, the connecting handle is released to feed material 101, causing the connecting spring to extend and the connecting block two feeding 102 to slide backward. This causes the connecting block two feeding 102 to engage with the front engaging groove feeding 112. At this time, the discharge motor is started, causing the lower positioning roller feeding 43 to rotate, thus moving the woven fabric to the left.

[0050] At the same time, the output motor is started, so that the fabric is fed at a constant speed onto the upper surface of the feed plate 31.

[0051] Then, the cutting motor feed 81 is activated, causing the output end of the cutting motor feed 81 to rotate. This causes the cutting connecting rod feed 83 to slide back and forth along the inner cavity of the sliding frame feed 82, thereby moving the laser cutting blade back and forth, achieving rapid cutting of the fabric. Simultaneously, the heating structure feed 5 is activated, and the heating element feed 53 is activated via the heating control module feed 54, heating the cutting base plate feed 51. This raises the temperature of the woven bag surface on the cutting base plate feed 51, reducing heat loss during subsequent laser cutting.

[0052] Meanwhile, the processed woven bags are piled up on the upper end of the feeding plate 31 for easy use by personnel. During cutting, the bags are stably clamped and fixed by the downward pressure of the inner rod feeding 63 and the speed limit of the feeding 7 of the speed limiting structure.
