Description

Technical Field

[0001] This invention belongs to the field of ton bag production and processing technology, specifically relating to a slitting machine and slitting method for ton bag production. Background Technology

[0002] BOOM (Flexible Intermediate Bulk Container) bags, also known as flexible intermediary bags or space bags, are medium-sized packaging containers used for transporting and storing large quantities of bulk materials. BOOM bags consist of a base fabric and lifting straps.

[0003] Ton bags are made primarily of polypropylene, with a small amount of stabilizing agents added for uniform mixing. The mixture is then melt-extruded into a plastic film using an extruder, cut into filaments, stretched, and heat-set to produce high-strength, low-elongation PP filaments. These filaments are then woven and laminated to create a woven plastic base fabric, which is then sewn together with accessories such as straps to form the ton bag. In the production process, the straps are first manually wound into a cylindrical roll, then secured with tape to prevent unwinding. The roll is then fed into a cutting and edge-sealing machine, which cuts it into multiple smaller cylinders of a predetermined size. Further processing is then performed to form the straps, which are finally sewn to the base fabric.

[0004] During the production process, the inventors discovered that this method of cutting raw materials required manual replacement of the cut cylindrical rolls and manual fixing, which consumed a lot of labor and involved cumbersome procedures with many unnecessary operations, resulting in low overall production efficiency.

[0005] Therefore, this study aims to improve upon the existing structure and its shortcomings, and to provide a slitting machine and slitting method for producing ton bags, in order to achieve a more practical purpose. Summary of the Invention

[0017] A slitting method for producing ton bags, using the aforementioned slitting machine for producing ton bags, includes the following steps:

[0018] S1 First, the roller is fed into the positioning shaft and moved into the positioning groove. Then, the extrusion arc plate is used to press and fix the roller. The rotating disk is controlled to rotate, so that the positioning shaft with the roller moves to one side of the winding shaft. Then, the raw material strip is bonded and fixed to the corresponding roller. Next, the adjusting ring plate is controlled to rotate, so that the rotating roller can drive the raw material strip to wind automatically.

[0019] S2 feeds the new roller into the positioning shaft at the same position, and when the raw material belt stops winding, controls the extrusion arc plate to extrude and fix the roller.

[0020] S3 then controls the rotary table to rotate at the set angle again. The roller carrying the raw material strip moves to the limiting plate and is squeezed against the limiting plate. The new roller moves to the same position as the previous roller. At this time, the extrusion plate is controlled to squeeze the raw material strip onto the roller. Then, the cutting plate is controlled to cut the raw material strip. At the same time as cutting, the gluing mechanism applies glue to the bottom of the raw material strip at both ends of the cutting plate. This allows the raw material strip to automatically bond and fix itself onto the new roller. Then, by adjusting the ring plate, the two rollers rotate synchronously. The extrusion at the limiting plate allows the raw material strip at the limiting plate to automatically bond and fix itself, forming a complete cylindrical shape. The new roller can then wind the raw material strip again.

[0021] After S4 is wound again, repeat the above steps S2-S3 to automatically change different rollers for winding and fixing of the raw material strip. The rollers that are pressed and bonded by the limiting plate move to the slitting saw with the rotating disk. The cylindrical raw material strip is cut into round cakes of a set width by the cutting of the slitting saw. The raw material strip can be slitting at the same time as it is being wound.

[0022] After the S5 slitting is completed, as the rotary table rotates, the next wound raw material strip moves again and is slitting again at the slitting saw. The cut raw material strip moves to the next area, and the control extrusion arc plate contacts the fixed roller. At this time, the cut raw material strip can be separated from the positioning shaft.

[0023] Compared with the prior art, the present invention has the following technical effects:

[0024] It integrates automatic winding, automatic changing, automatic cutting and automatic discharge of raw material strips, effectively improving overall production efficiency, increasing automation level and greatly reducing labor costs.

[0025] The design of the rotary disc, winding shaft, adjusting ring plate, extrusion plate, cutting disc, gluing mechanism, and limiting plate enables the automatic winding, automatic replacement, and automatic cutting of raw material strips into one integrated design. This solves the problem of having to manually fix the raw material strip into a cylindrical shape with tape after winding it into a roll before feeding it into the edge-cutting machine for slitting. This effectively improves the overall production efficiency while greatly reducing the number of workers and lowering labor costs.

[0026] The synchronous chain enables the synchronized movement of multiple adjusting ring plates, while the first hydraulic rod controls the back-and-forth movement of the extrusion arc plate. By squeezing and fixing the extrusion arc plate with the roller, the roller rotation can be controlled. Once the roller is squeezed and fixed, the roller will stop rotating, thus achieving selective rotation of the roller.

[0027] The design of the extension tube, one-way valve, and hollow tube allows the extension tube to automatically extend and engage with the recycling tank by releasing air from the air pump and increasing the air pressure. By drawing air from the air pump, the spring hose automatically retracts, thereby moving the feeding rod and automatically separating the rollers, thus achieving automatic discharge of the cut raw material strip.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or may be interposed with another element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] Example 1, please refer to Figure 1 , Figure 2 and Figure 3A raw material strip cutting device includes a cutting base 1, a rotatable rotating disk 11 on the cutting base 1, multiple evenly distributed annular positioning grooves on the rotating disk 11, a fixedly connected positioning shaft 10 in each positioning groove, and a rotatable adjusting ring plate 112 in each positioning groove. A rotatably connected roller is located outside the positioning shaft 10. An extrusion arc plate 111, movable back and forth, is located inside the adjusting ring plate 112 for pressing and fixing the end of the roller. A rotatable winding shaft is located on one side of the cutting base 1, on which a uniformly wound raw material strip 3 is mounted. The cutting base 1 is equipped with a reciprocating... An extrusion plate 22 is provided on the cutting base 1 to press the raw material strip 3 onto the positioning shaft 10. The extrusion plate 22 is provided with a cutting disc 23 that can move back and forth and is used to cut the raw material strip 3. The front end of the cutting disc 23 is provided with a gluing mechanism for applying glue to the bottom of the raw material strip 3. An adjustment base that can move back and forth along the positioning shaft 10 is provided on the other side of the cutting base 1. A slitting saw disc 14 that can move back and forth and is used to cut the raw material strip 3 into strips is provided on the adjustment base. A material-pulling rod 104 that can move back and forth and is used to separate the roller from the positioning shaft 10 is provided on the positioning shaft 10. A limiting plate 12 that is used to press and bond the raw material strip 3 after it is wound is provided on the cutting base 1. The slitting motor 141 is fixedly connected to the adjustment base. The output end of the slitting motor 141 is fixedly connected to the slitting saw disc 14. At the same time, the back and forth movement of the adjustment base and the reciprocating movement of the slitting saw disc 14 on the adjustment base are existing technologies in the field of edge-cutting machines (rolling strip cutting machines or bundling cutting machines), so this application will not describe them in detail.

[0047] The design of the rotary disc 11, winding shaft, adjusting ring plate 112, extrusion plate 22, cutting disc 23, gluing mechanism and limiting plate 12 enables the automatic winding, automatic replacement and automatic cutting of raw material strip 3 into one integrated design. It solves the problem of the original need to wind the raw material strip 3 into a roll, fix it into a cylindrical shape with tape, and then send it into the edge-cutting machine for slitting. It effectively improves the overall production efficiency, while greatly reducing the number of workers and reducing labor costs.

[0048] In this embodiment, please refer to Figure 4 , Figure 5 and Figure 6The extrusion plate 22 has a cutting groove 222, and the cutting disc 23 is movably disposed within the cutting groove 222. A power groove 223 is located on one side of the cutting groove 222, and a sliding plate 232 is slidably connected within the power groove 223. A first motor 231 is fixedly connected to the sliding plate 232, and an output shaft 238 is fixedly connected to the output disc 23. A drive groove 221 is located on the other side of the cutting groove 222, and a rack 224 is fixedly connected within the drive groove 221. A gear 239 meshing with the rack 224 is located at the end of the output shaft 238. A mounting plate 2 is fixedly connected to the cutting base 1, and a fifth hydraulic rod 21 is fixedly connected to the mounting plate 22. The fifth hydraulic rod 21 is fixedly connected to the extrusion plate 22. The first motor 231 is a reversible motor.

[0049] The first motor 231 drives the cutting disc 23 to rotate to achieve cutting. At the same time, the rotation of the first motor 231 can drive the gear 239 to mesh with the rack 224, thereby realizing the reciprocating motion of the cutting disc 23, thus enabling the cutting disc 23 to cut and separate back and forth.

[0050] In this embodiment, please refer to Figure 5 and Figure 6 The gluing mechanism includes a gluing plate 237, a storage tank 233, and a delivery pump. The storage tank 233 stores glue for bonding and fixing the raw material belt 3 to the roller. The gluing plate 237 moves synchronously with the cutting disc 23, and multiple gluing holes 236 are provided at both ends of the gluing plate 237. The storage tank 233 is fixedly mounted on the slide plate 232, and the delivery pump is installed inside the storage tank 233. The output end of the delivery pump is connected to the gluing holes 236 through a pipe. The ends of the gluing plate 237 are inclined.

[0051] The design of the delivery pump and the glue application hole 236 enables the glue to be delivered to the glue application hole 236 in a timely manner through the pump, so that the glue can be evenly applied to the bottom of the raw material belt 3, ensuring the bonding stability of the raw material belt 3. The inclined design of the end of the glue application plate 237 enables the glue application plate 237 to move to the bottom of the raw material belt 3 better, and makes the raw material belt 3 fit more closely with the glue application hole 236, improving the uniformity of glue application.

[0052] In this embodiment, please refer to Figure 5The bottom of the extrusion plate 22 located on one side of the limiting plate 12 is provided with adhesive that can be torn and separated from the raw material strip 3. A synchronization plate 235 is fixedly connected to the slide plate 232. One end of the synchronization plate 235 is fixedly connected to the adhesive coating plate 237, and the other end of the synchronization plate 235 is rotatably connected to a pressure roller 234 for pressing and bonding the raw material strip 3 onto the positioning shaft 10. The adhesive and pressure roller 234 are located on opposite sides of the cutting disc 23, and the adhesive is a nano-adhesive. The pressure roller 234 allows the raw material strip 3 to better bond and fix itself to the corresponding roller after cutting and separation. The adhesive provides good stability to the raw material strip 3 during cutting and prevents it from automatically falling off due to gravity after cutting.

[0053] In this embodiment, please refer to Figure 1 , Figure 3 and Figure 7 The cutting base 1 is equipped with a fixedly connected positioning plate 13. The positioning plate 13 has a through-hole in its center, and a rotatably connected positioning disc 131 is located within the positioning hole. The positioning disc 131 has multiple discharge holes 135 corresponding to the positioning slots and used for separating the raw material strip 3 after cutting. Each discharge hole 135 has a reciprocating discharge plate 134, and a fixedly connected support rod 132 is located on the discharge plate 134. The end of the positioning shaft 10 has a support groove for engaging and supporting the support rod 132. A fourth hydraulic rod 133 is located within the discharge hole 135 to drive the discharge plate 134 up and down. When the discharge plate 134 moves downwards, the support rod 132 automatically separates from the support groove, ensuring that the support rod 132 does not affect the overall operational stability.

[0054] The design of the support rod 132 and the support groove enables the roller to provide a certain degree of support when winding or cutting the raw material belt 3, preventing the positioning shaft 10 from tilting.

[0055] In this embodiment, please refer to Figure 8 The rotating disk 11 is provided with an adjustment groove 113, which passes through the positioning groove. An adjustment ring plate 112 is set in the positioning groove. The upper and lower ends of the adjustment ring plate 112 are rotatably connected to the adjustment groove 113. Multiple first hydraulic rods 115 are provided on the inner side of the adjustment ring plate 112. The extended ends of the first hydraulic rods 115 are fixedly connected to the corresponding extrusion arc plates 111. An adjustment shaft 114 is provided in the middle of the adjustment groove 113. A synchronous chain 116 is connected between the adjustment shaft 114 and the adjustment ring plate 112. A second motor for driving the adjustment shaft 114 to rotate is provided in the cutting base 1. A rotating shaft is fixedly connected to the outer side of the rotating disk 11. The rotating shaft is rotatably connected to the side wall of the cutting base 1. A third motor for driving the rotating shaft to rotate is provided in the cutting base 1.

[0056] The synchronous chain 116 enables the synchronous movement of multiple adjusting ring plates 112, while the first hydraulic rod 115 controls the back-and-forth movement of the extrusion arc plate 111. By extruding and fixing the extrusion arc plate 111 to the roller, the rotation of the roller can be controlled. Once the roller is pressed and fixed, the roller will stop rotating, thus achieving selective rotation of the roller.

[0057] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 9 The cutting base 1 is provided with a discharge box 151 that can move up and down. The discharge box 151 is provided with a discharge shaft 15. The end of the discharge shaft 15 is located outside the discharge hole 135 at the bottommost position, and the end of the discharge shaft 15 is aligned with the positioning shaft 10.

[0058] In this embodiment, please refer to Figure 9 and Figure 10 The outer end of the positioning shaft 10 is provided with a recycling groove 102, and the positioning shaft 10 is provided with a limiting groove 103 that communicates with the recycling groove 102. The feeding rod 104 is slidably connected in the limiting groove 103. The recycling groove 102 is provided with a retractable spring hose 101. One end of the spring hose 101 is fixedly connected to the feeding rod 104, and the other end of the spring hose 101 is fixedly connected to the inlet of the recycling groove 102. The discharge shaft 15 is a hollow tube, and the extended end of the discharge shaft 15 is provided with a sliding and sealed extension tube 157. The extension tube 157 is engaged and sealed with the inlet of the recycling groove 102, and the extension tube 157 is provided with a one-way valve 158 for one-way airflow. The discharge box 151 is provided with an air pump 153 that can pump and release air, and the discharge box 151 is provided with an air inlet. The output end of the air pump 153 is connected to the air inlet through a pipe. The bottom of the discharge shaft 15 is slidably and sealed with the discharge box 151.

[0059] The design of the extension tube 157, one-way valve 158, and hollow tube allows the extension tube 157 to automatically extend and engage with the recovery tank 102 by releasing air from the air pump 153 and increasing the air pressure. By drawing air from the air pump 153, the spring hose 101 automatically retracts, thereby moving the material feeding rod 104 and automatically separating the rollers, thus achieving automatic discharge of the raw material belt 3 after cutting.

[0060] In this embodiment, please refer to Figure 9 and Figure 10 The bottom of the discharge box 151 is provided with a second hydraulic rod 154 for driving the discharge box 151 to move up and down. The cutting base 1 is provided with a third hydraulic rod 152 fixedly connected to one side. The extension end of the third hydraulic rod 152 is provided with a clamping rod 156 fixedly connected. The discharge shaft 15 is provided with a clamping groove 155 that can be detached from the clamping rod 156 on one side. The discharge box 151 is provided with a U-shaped limit frame for limiting the movement trajectory of the discharge shaft 15.

[0061] As a feasible implementation, an openable clamp can also be provided at the end of the third hydraulic rod 152. When the third hydraulic rod 152 moves to the discharge shaft 15, the clamp can be used to clamp and fix the discharge shaft 15, so that the discharge shaft 15 can be controlled to move back and forth by the third hydraulic rod 152.

[0062] A slitting method for producing ton bags, using a slitting machine for ton bag production, includes the following steps:

[0063] S1 First, the roller is fed into the positioning shaft 10 and the roller is moved into the positioning groove. Then, the extrusion arc plate 111 is used to extrude and fix the roller. The rotating disk 11 is controlled to rotate so that the positioning shaft 10 with the roller moves to one side of the winding shaft. Then, the raw material belt 3 is bonded and fixed to the corresponding roller. Next, the adjusting ring plate 112 is controlled to rotate so that the rotating roller can drive the raw material belt 3 to wind automatically.

[0064] S2 feeds the new roller into the positioning shaft 10 at the same position. When the raw material belt 3 stops winding, the extrusion arc plate 111 is controlled to extrude and fix the roller.

[0065] S3 then controls the rotating disk 11 to rotate at a set angle again. The roller carrying the raw material strip 3 moves to the limiting plate 12 and is squeezed against the limiting plate 12. The new roller moves to the same position as the previous roller. At this time, the extrusion plate 22 is controlled to squeeze the raw material strip 3 onto the roller. Then, the cutting disk 23 is controlled to cut the raw material strip 3. At the same time as cutting, the glue application mechanism applies glue to the bottom of the raw material strip 3 at both ends of the cutting disk 23. This allows the raw material strip 3 to automatically bond and fix itself onto the new roller. Then, by adjusting the ring plate 112, the two rollers rotate synchronously. The extrusion at the limiting plate 12 allows the raw material strip 3 at the limiting plate 12 to automatically bond and fix itself, forming a complete cylindrical shape. The new roller can then wind the raw material strip 3 again.

[0066] After S4 is wound again, repeat the above steps S2-S3 to make the raw material strip 3 automatically change to different rollers for winding and fixing. The rollers that are pressed and bonded by the limiting plate 12 move to the slitting saw 14 with the rotating disk 11. The cylindrical raw material strip 3 is cut into round cakes of a set width by the cutting of the slitting saw 14. The raw material strip 3 can be slitting at the same time as it is being wound.

[0067] After the S5 slitting is completed, as the rotary disk 11 rotates, the next wound raw material strip 3 moves again and is slitting again at the slitting saw disk 14. The cut raw material strip 3 moves to the next area and controls the extrusion arc plate 111 to contact the fixed roller. At this time, the cut raw material strip 3 can be separated from the positioning shaft 10.

[0068] In this application, the slitting machine is used as follows:

[0069] (1) First, control the discharge box 151 to move downward so that the discharge shaft 15 is below the discharge hole 135. At the same time, control the discharge plate 134 to move downward to open the discharge hole 135. Then, manually feed the roller into the positioning shaft 10 so that the roller moves to the extrusion arc plate 111. At this time, the push rod 104 is located inside the extrusion arc plate 111 and does not contact it. Then, control the roller of the extrusion arc plate 111 to extrude and fix it.

[0070] (2) Control the rotating disk 11 to rotate so that the roller moves to one side of the winding shaft. Manually fix the raw material belt 3 to the roller. Then control the adjusting ring plate 112 to rotate so that the raw material belt 3 is automatically wound on the roller. While winding, the new roller is sent to the positioning shaft 10 again after repeating step (1). When the raw material belt 3 stops winding, control the extrusion arc plate 111 to extrude and fix the roller.

[0071] (3) After winding, the rotary disc 11 is rotated, causing the roller carrying the raw material strip 3 to move to the limiting plate 12 and be squeezed and limited by the limiting plate 12. At the same time, the new roller moves to the position of the previous roller. At this time, the extrusion plate 22 is controlled to move, squeezing the raw material strip 3 onto the roller. Then, the cutting disc 23 is controlled to move. Before the cutting disc 23 cuts the raw material strip 3, the adhesive plate 237 can move to below the raw material strip 3. At the same time, the conveying pump is controlled to deliver the adhesive to the adhesive hole 236, so that the adhesive is automatically applied to the bottom of the raw material strip 3. Then, with the movement of the cutting disc 23, the raw material strip 3 can be cut and separated. The presence of adhesive can prevent the raw material strip 3 from falling off and separating immediately after cutting. To maintain a relatively intact surface and ensure the cutting effect; after cutting, as the cutting disc 23 moves, the pressure roller 234 will automatically squeeze and bond the raw material strip 3 coated with glue to the roller. After the cutting is completed, the pressure of the extrusion plate 22 is released, and only the roller needs to be rotated. The pulling force of the rotation is greater than the adhesive force of the glue, so that the raw material strip 3 is automatically separated from the extrusion plate 22. Due to the presence of the limiting plate 12, the raw material strip 3 with glue can be automatically wound as the roller rotates and squeezed by the limiting plate 12, so that the wound raw material strip 3 can form a complete cylindrical shape. The new roller can automatically wind the raw material strip 3, thereby realizing the automatic replacement and automatic winding of the raw material strip 3.

[0072] (4) Control the rotating plate to move the wound raw material strip 3 to the slitting saw 14, and slitting the raw material strip 3 to the set size by the slitting saw 14.

[0073] (5) After the raw material strip 3 is cut, it moves to the discharge shaft 15 again. The discharge box 151 is controlled to move upward so that the discharge shaft 15 is aligned with the positioning shaft 10. Then the discharge plate 134 is moved downward to open the discharge hole 135. At the same time, the extrusion arc plate 111 is controlled to contact the roller and fix it. Then the air pump 153 is controlled to output airflow. Due to the presence of the one-way valve 158, the extension tube 157 automatically extends, so that the extension tube 157 is locked and fixed with the recycling tank 102. Then the air pump 153 is controlled to draw airflow to form negative pressure, which drives the spring hose 101 to automatically retract, so that the feeding rod 104 pushes the rollers containing the raw material strip 3 one by one. Separated from the positioning shaft 10, the material falls onto the discharge box 151 via the discharge rod. After the rollers are completely separated, the third hydraulic rod 152 is extended to engage the locking rod 156 with the locking groove 155, causing the discharge rod to move outward until the extension tube 157 separates from the discharge hole 135. Then, the discharge box 151 is moved upward so that the discharge shaft 15 does not affect the entry of the new rollers onto the positioning shaft 10. After the discharge shaft 15 separates from the discharge box 151, the material belt 3 on the discharge shaft 15 will automatically fall off and separate from the discharge shaft 15. Then, the discharge shaft 15 is restored to its initial position and moves to the air inlet, and the locking rod 156 separates from the locking groove 155.

[0074] This achieves automatic winding, automatic replacement, automatic cutting and automatic discharge of raw material belts, effectively improving overall production efficiency.

6. A slitting method for producing ton bags, employing the slitting machine for producing ton bags according to any one of claims 1-5, characterized in that, Includes the following steps: S1 First, the roller is fed into the positioning shaft and moved into the positioning groove. Then, the extrusion arc plate is used to press and fix the roller. The rotating disk is controlled to rotate, so that the positioning shaft with the roller moves to one side of the winding shaft. Then, the raw material strip is bonded and fixed to the corresponding roller. Next, the adjusting ring plate is controlled to rotate, so that the rotating roller can drive the raw material strip to wind automatically. S2 feeds the new roller into the positioning shaft at the same position, and when the raw material belt stops winding, controls the extrusion arc plate to extrude and fix the roller. S3 then controls the rotary table to rotate at the set angle again. The roller carrying the raw material strip moves to the limit plate and is squeezed against the limit plate. The new roller moves to the same position as the previous roller. At this time, the extrusion plate is controlled to squeeze the raw material strip onto the roller. Then, the cutting plate is controlled to cut the raw material strip. At the same time as cutting, the gluing mechanism applies glue to the bottom of the raw material strip at both ends of the cutting plate. This allows the raw material strip to automatically bond and fix itself onto the new roller. Then, by adjusting the ring plate, the two rollers rotate synchronously. The extrusion at the limit plate allows the raw material strip at the limit plate to automatically bond and fix itself, forming a complete cylindrical shape. The new roller can then wind the raw material strip again. After S4 is wound again, repeat the above steps S2-S3 to automatically change different rollers for winding and fixing of the raw material strip.
