Description

Technical Field

[0001] This utility model belongs to the field of container bag production technology, and more specifically, it relates to a container bag cutting device with a guiding structure. Background Technology

[0002] FIBCs (Flexible Intermediate Bulk Containers) are flexible transport packaging containers widely used for transporting powdery, granular, and lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals. Developed countries commonly use FIBCs for transportation and warehousing. In the production process of FIBCs, fabric cutting is a crucial step, and the selection and replacement of cutting tools directly affect the quality and efficiency of fabric cutting.

[0003] Currently, FIBC (Flexible Intermediate Bulk Container) fabric cutting devices often have some shortcomings in terms of blade changing. On the one hand, the blade changing process in many cutting devices is quite complex, requiring specialized tools and technicians. This not only increases production costs but also affects production schedules due to excessively long blade changing times. On the other hand, existing blade changing methods also lack adaptability and flexibility in terms of blades. Different types of FIBC materials and cutting requirements necessitate different blades; however, traditional devices often struggle to quickly switch to the appropriate blade. This limits production efficiency when facing diverse production demands.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a container bag cutting device with a guiding structure, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a container bag fabric cutting device with a guiding structure, which is achieved by the following specific technical means:

[0006] A container bag cutting device with a guiding structure includes a first conveyor belt and a second conveyor belt. A guiding mechanism is provided above both the first and second conveyor belts. Supports are provided at both ends of opposite sides of the first and second conveyor belts. An upper cutter is slidably installed between the two sets of supports. Support frames are installed on both sides of the bottom of the first and second conveyor belts. Mounting frames are also installed at the bottom of the left and right support frames. A cross-shaped track is provided on one side of each mounting frame. Two sets of sliders are slidably installed within the track. A first lower cutter and a second lower cutter are respectively installed on the front side of the two sets of sliders. A connecting plate is rotatably installed on the rear side of the two sets of sliders. A driven gear is rotatably installed in the middle of the connecting plate. A driving gear is meshed on one side of the driven gear, and a drive motor is connected to one side of the driving gear.

[0007] Both the drive gear and the output end of the drive motor are equipped with pulleys, and a belt connects the two sets of pulleys. A base plate is fixedly installed on the bottom side of the drive motor, and the bottom ends of the two sets of mounting brackets are fixedly connected to the top end of the base plate.

[0008] The guiding mechanism includes mounting blocks installed on the left and right sides of the top of the first and second conveyor belts. A second rotating rod is rotatably mounted between the left and right mounting blocks. Multiple pressure rollers are equidistantly mounted on the outer wall of the second rotating rod.

[0009] Both sets of brackets have grooves on opposite sides. Both ends of the upper cutter are slidably connected to the corresponding grooves. Sliding columns are installed in the two sets of grooves. Springs are fitted on the outer walls of the two sets of sliding columns. The springs are set between the bottom side of the upper cutter and the bottom end of the groove.

[0010] Two sets of brackets are each rotatably mounted on one side of the brackets. Multiple sets of cams are equidistantly fitted on the outer wall of the first rotating rod. The outer walls of the multiple sets of cams are all set to abut against the top of the upper cutter. Both ends of the first rotating rod are fixedly fitted with pulleys. The outer wall of the pulleys is provided with a belt, and the pulleys and belts are connected to the drive motor for transmission.

[0011] The surface of the pressure roller is provided with anti-slip texture.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The drive motor of this utility model drives the active gear to rotate via a belt and pulley. The active gear meshes with the driven gear, which drives the connecting plate to rotate, thereby driving two sets of sliders to slide within a cross-shaped track, realizing the switching between the first and second lower cutters. At the same time, the reciprocating forward and reverse rotation of the active gear is transmitted through the driven gear, causing the first or second lower cutter to reciprocate up and down. This, in turn, cooperates with the upper cutter, which slides up and down between the supports via a cam and a spring buffer, to cut the fabric of the container bag. This solves the problems of difficult tool switching and insufficient cutting adaptability in the prior art, and improves the accuracy and efficiency of cutting.

[0014] 2. This utility model uses mounting blocks installed on the left and right sides of the top of the first and second conveyor belts, and a second rotating rod rotatably mounted between them. Multiple sets of pressure rollers, equidistantly mounted on the outer wall of the second rotating rod, guide and compact the fabric. In terms of guidance, this structure ensures the fabric maintains the correct direction of travel during conveying, accurately entering the cutting area and avoiding inaccurate cutting positions due to fabric deviation, thereby improving cutting accuracy and quality. In terms of compaction, the anti-slip texture on the surface of the pressure rollers increases friction with the fabric, not only guiding the fabric better but also compacting it, effectively preventing wrinkles during cutting and further ensuring cutting accuracy and quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a bag cutting device with a guiding structure, including a first conveyor belt 1 and a second conveyor belt 2. A guiding mechanism is provided above the first conveyor belt 1 and the second conveyor belt 2. Supports 3 are provided at both ends of the first conveyor belt 1 and the second conveyor belt 2 on opposite sides. An upper cutter 6 is slidably installed between the two sets of supports 3. Support frames 11 are installed on both sides of the bottom of the first conveyor belt 1 and the second conveyor belt 2. Mounting frames 12 are installed at the bottom of the left and right support frames 11. A cross-shaped track 17 is opened on one side of the two sets of mounting frames 12. Two sets of sliders 13 are slidably installed in the track 17. A first lower cutter 15 and a second lower cutter 16 are respectively installed on the front side of the two sets of sliders 13. A connecting plate 14 is rotatably installed on the rear side of the two sets of sliders 13. A driven gear 18 is rotatably installed in the middle of the connecting plate 14. A driving gear 19 is meshed on one side of the driven gear 18. A drive motor 20 is drivenly connected to one side of the driving gear 19.

[0025] Among them, pulleys are installed on one side of the drive gear 19 and the output end of the drive motor 20, and a belt is connected between the two sets of pulleys. A base plate 7 is fixedly installed on the bottom side of the drive motor 20, and the bottom ends of the two sets of mounting brackets 12 are fixedly connected to the top end of the base plate 7.

[0026] The guiding mechanism includes mounting blocks installed on the left and right sides of the top ends of the first conveyor belt 1 and the second conveyor belt 2. A second rotating rod 21 is rotatably mounted between the left and right mounting blocks. Multiple pressure rollers 22 are equidistantly mounted on the outer wall of the second rotating rod 21. The guiding mechanism guides and compacts the fabric by using the mounting blocks installed on the left and right sides of the top ends of the first conveyor belt 1 and the second conveyor belt 2, and the second rotating rod 21 rotatably mounted between them, in conjunction with the multiple pressure rollers 22 equidistantly mounted on the outer wall of the second rotating rod 21. The anti-slip texture on the surface of the pressure rollers 22 increases the friction between the fabric and the fabric, so that the fabric can be accurately guided during the conveying process, preventing the fabric from shifting or wrinkling, ensuring that the fabric enters the cutting area smoothly, and improving the cutting quality.

[0027] Each of the two sets of brackets 3 has a sliding groove 8 on one side. Both ends of the upper cutter 6 are slidably connected to the corresponding sliding groove 8. Sliding columns 9 are installed in the two sets of sliding grooves 8. Springs 10 are fitted on the outer walls of the two sets of sliding columns 9. The springs 10 are set between the bottom side of the upper cutter 6 and the bottom end of the sliding groove 8. The sliding grooves 8 on the opposite sides of the two sets of brackets 3 provide sliding space for the upper cutter 6. The sliding connection between the two ends of the upper cutter 6 and the sliding groove 8 ensures that the upper cutter 6 can slide up and down during the cutting process. The sliding columns 9 installed in the sliding grooves 8 provide precise guidance for the sliding of the upper cutter 6, ensuring that the upper cutter 6 moves along the predetermined trajectory and improving cutting accuracy. The springs 10 fitted on the outer walls of the sliding columns 9 play a buffering role. When the upper cutter 6 is subjected to a large cutting force, the springs 10 can absorb some energy to prevent the upper cutter 6 from being damaged due to excessive force. At the same time, it also helps the upper cutter 6 to quickly reset after cutting and achieve stable cutting movement.

[0028] In this system, two sets of brackets 3 are each rotatably mounted on opposite sides with a first rotating rod 4. Multiple sets of cams 5 are equidistantly fitted onto the outer wall of the first rotating rod 4, and the outer walls of these cams 5 abut against the top of the upper cutter 6. Both ends of the first rotating rod 4 are fixedly fitted with pulleys, and belts are mounted on the outer walls of the pulleys. These pulleys and belts are connected to the drive motor 20 for transmission. When the first rotating rod 4 rotates, the cams 5 rotate accordingly. Through the contact between the cams 5 and the upper cutter 6, the upper cutter 6 can be effectively pushed to slide up and down within the groove 8, thus achieving the cutting action of the upper cutter 6. This driving method can precisely control the movement trajectory and cutting depth of the upper cutter 6 according to the contour design of the cams 5, adapting to fabrics of different thicknesses and improving cutting quality.

[0029] The surface of the pressure roller 22 is provided with anti-slip texture.

[0030] The working principle of this embodiment is as follows: The drive motor 20 is started, and power is transmitted to the drive gear 19 through the pulley and belt. The drive gear 19 drives the driven gear 18, which meshes with it, to rotate. Simultaneously, the first rotating rod 4 also begins to rotate, thereby driving the first conveyor belt 1 and the second conveyor belt 2 to start operating. The fabric of the container bag is placed on the first conveyor belt 1, and as the first conveyor belt 1 rotates, the fabric moves towards the cutting area.

[0031] Fabric Guiding: The guiding mechanism plays a crucial role during fabric conveying. The second rotating rod 21 rotates between the mounting blocks, and multiple sets of pressure rollers 22 on its outer wall contact the fabric. Because the surface of the pressure rollers 22 is textured with anti-slip patterns, the friction between the rollers and the fabric is increased, allowing the fabric to be accurately guided during conveying. The pressure rollers 22 automatically adjust their rotation direction according to the fabric's travel direction, ensuring the fabric always maintains the correct travel direction, preventing fabric deviation or wrinkles, and allowing the fabric to smoothly enter the cutting area.

[0032] Cutting stage

[0033] Cutting with the upper cutter 6: When the fabric enters the cutting area, the rotation of the first rotating rod 4 drives the cam 5 to rotate. The outer wall of the cam 5 abuts against the top of the upper cutter 6. As the cam 5 rotates, it pushes the upper cutter 6 to slide downwards in the groove 8 of the bracket 3, beginning to cut into the fabric. The sliding post 9 in the groove 8 provides precise guidance for the sliding of the upper cutter 6, and the spring 10 fitted on the outer wall of the sliding post 9 acts as a buffer. As the cam 5 continues to rotate, after the upper cutter 6 reaches its maximum cutting depth, it returns to its original position upwards with the assistance of the elastic force of the spring 10, completing one cutting action. This process is repeated to perform the cutting.

[0034] The lower cutter cooperates with the cutting: Simultaneously, the rotation of the driven gear 18 drives the connecting plate 14 to rotate, which in turn drives the two sets of sliders 13 to slide within the cross-shaped track 17. The first lower cutter 15 and the second lower cutter 16 mounted on the front side of the slider 13 move with the sliding of the slider 13. The reciprocating forward and reverse rotation of the driving gear 19 is accurately transmitted to the slider 13 through the driven gear 18, enabling the first lower cutter 15 and the second lower cutter 16 to reciprocate up and down, cooperating with the cutting action of the upper cutter 6. When the first lower cutter 15 and the second lower cutter 16 descend, they work together with the upper cutter 6 to complete the cutting of the fabric, ensuring a neater and smoother cutting effect and reducing edge defects after cutting.

[0035] Down-cutting blade switching process

[0036] The driven gear 18 drives the connecting plate 14 to rotate. Since the rear sides of the two sets of sliders 13 are rotated together with the connecting plate 14, the rotation of the connecting plate 14 drives the two sets of sliders 13 to slide within the cross-shaped track 17. When the slider 13 slides, the first lower cutter 15 and the second lower cutter 16 mounted on its front side move accordingly. When the slider 13 slides to a predetermined position, the switching between the first lower cutter 15 and the second lower cutter 16 can be achieved. For example, if the first lower cutter 15 was originally used, by sliding the slider 13 to the position corresponding to the second lower cutter 16 through the above operation, the tool switching is completed.

[0037] Post-cutting processing stage

[0038] Fabric conveying continues: After cutting, the fabric continues to be conveyed forward under the action of the first conveyor belt 1 and the second conveyor belt 2. The second conveyor belt 2 receives the cut fabric and conveys it to the next process or collection area.

Many modifications and variations will be apparent to those skilled in the art.
