Description

Technical Field

[0001] This utility model relates to the field of folding edges for the production of ton bag FIBCs, and more particularly to a folding edge mechanism for the production of ton bag FIBCs. Background Technology

[0002] A ton bag is a high-strength, flexible packaging container used for transporting bulk materials. The folding mechanism precisely folds the edges of the material through mechanical movement to ensure the sealing, strength, or aesthetics of the processed parts.

[0003] There are still some problems in the use of existing folding mechanisms for ton bag production. The current folding mechanisms for ton bag production cannot effectively control the consistency of the folded width of the ton bag, nor can they adjust the flatness of the ton bag. Therefore, those skilled in the art provide a folding mechanism for ton bag production to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a folding mechanism for the production of ton bag containers, which effectively improves the consistency and flatness of the folded edge width of ton bag containers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a folding mechanism for producing ton bag containers, comprising a base and a bottom plate, wherein the bottom plate is located at the center of the upper end face of the base, and a folding device is provided at the upper end of the bottom plate;

[0006] The folding device includes a first sliding groove, a sliding plate slidably connected to the front end of the first sliding groove, a limit cover plate rotatably connected to the upper end of the sliding plate, the limit cover plate being located on one side of the upper end of the base, an adhesive plate being provided at the lower end of the limit cover plate on the upper surface of the base, connecting columns being provided at both the front and rear ends of the upper surface of the base near the limit cover plate, connecting blocks being fixedly connected to the upper surfaces of the two connecting columns, and second electric telescopic rods being provided at the lower surfaces of the two connecting blocks away from the center of the base, the upper surfaces of the two second electric telescopic rods respectively penetrating through the lower surfaces of the two connecting blocks and extending into the interior of the two connecting blocks, the output ends of the two second electric telescopic rods being fixedly connected to a folding plate, and the output ends of the two second electric telescopic rods being fixedly connected to the front and rear ends of the upper surface of the folding plate respectively;

[0007] The above technical solution involves raising the folding plate to a position where its lower end is slightly higher than the upper end of the base plate by activating two second electric telescopic rods. One of the second electric telescopic rods is the main control drive, and the other folding plate is the auxiliary control drive. The main control drive drives the auxiliary control drive for synchronous extension and retraction, a common method in existing second electric telescopic rod synchronous control systems, which will not be elaborated upon here. The continuous rise of the folding plate raises the area requiring folding, and a limiting cover prevents the area of ​​the ton bag / FIBC that does not require folding from rising along with the folding plate. Then, the second... An electric telescopic rod drives the moving column to move inside the moving groove, which in turn drives the base plate to move. When the base plate starts to move, since the folded edge plate is only slightly higher than the base plate, the limiting cover plate located at the upper end of the base plate will not move due to the obstruction of the folded edge plate. Therefore, when the inner wall of the first sliding groove on the front end face of the base plate contacts the end face of the sliding plate near the center of the base plate, the movement will stop. At the same time, the folded edge plate in contact with the limiting cover plate will be located at the upper end of the sewing seam. The adhesive plate on the upper end face of the base plate can effectively prevent the ton bag from sliding upward during the movement of the base plate, ensuring that the folded edge width of the ton bag is consistent.

[0008] Furthermore, the upper end of the base plate is provided with a flat structure, which includes two T-shaped grooves. The two T-shaped grooves pass through the front and rear ends of the base plate and extend into the interior of the base plate. T-shaped sliders are slidably connected to both sides of the interior of the two T-shaped grooves. Movable plates are fixedly connected to the outer sides of the four T-shaped sliders. Grooves are provided on the upper rear ends of the two front movable plates and on the upper front ends of the two rear movable plates. Fixing blocks are provided inside the four grooves. Springs are fixedly connected to the upper ends of the four fixing blocks. The upper ends of the four springs are fixedly connected to the inner walls of the four grooves. Flattening wheels are rotatably connected to the center of the rear ends of the two front fixing blocks. The rear ends of the two flattening wheels are rotatably connected to the center of the front ends of the two rear fixing blocks.

[0009] With the above technical solution, when preparing to fold the edges of a ton bag, the ton bag to be folded is first lifted slightly by the springs inside the moving plate of the flattening structure, which slightly raises the two flattening rollers to ensure that the ton bag can be placed on the upper surface of the bottom plate. Then, four T-shaped sliders slide inside the two T-shaped grooves, thereby driving the four moving plates to slide, which in turn drives the two flattening rollers to slide on the upper end of the ton bag. Through the continuous sliding of the two flattening rollers, the ton bag is flattened, which facilitates the subsequent folding of the ton bag.

[0010] Furthermore, a baffle is fixedly connected to the lower end face of the base away from the folding device, and a first electric telescopic rod is fixedly connected to the end face of the baffle near the folding device. The end face of the first electric telescopic rod away from the folding device passes through the end face of the baffle near the folding device and extends into the interior of the baffle.

[0011] The above technical solution facilitates the movement of the moving column within the moving slot by activating the first electric telescopic rod.

[0012] Furthermore, a moving column is fixedly connected to the output end of the first electric telescopic rod, and a moving groove is provided at the center of the lower end face of the base. The upper end face of the moving column passes through the lower end face of the moving groove and extends to the lower end face of the base plate.

[0013] The above technical solution facilitates the movement of the base plate for folding the edges of ton-bag containers.

[0014] Furthermore, multiple seams are provided on the upper surface of the base plate near the folding device.

[0015] The above technical solution facilitates the sewing of ton-bag containers.

[0016] Furthermore, a sewing groove is provided at the center of the upper end face of the folded edge plate;

[0017] The above technical solution facilitates the observation of the flatness and fold width of the ton bag, and makes it easier to sew the ton bag.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the folding mechanism for producing ton bag FIBCs (Flexible Intermediate Bulk Containers) slightly lifts two flattening rollers by using springs inside the moving plates of the flattening structure to ensure that the ton bag FIBC can be placed on the upper surface of the bottom plate. Then, four T-shaped sliders slide inside two T-shaped grooves, thereby driving the four moving plates to slide, which in turn drives the two flattening rollers to slide on the upper end of the ton bag FIBC. Through the continuous sliding of the two flattening rollers, the ton bag FIBC is flattened, which facilitates the subsequent folding of the ton bag FIBC.

[0020] 2. In this utility model, the folding mechanism for producing ton bag containers prevents the areas of the ton bag container that do not need to be folded from rising along with the folding plate by setting a limiting cover plate. The adhesive plate set on the upper end of the bottom plate can effectively prevent the ton bag container from sliding upward during the movement of the bottom plate, thus ensuring that the folding width of the ton bag container is consistent.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 One embodiment of this utility model is a folding mechanism for producing ton bag containers, including a base 1 and a bottom plate 3. The bottom plate 3 is located at the center of the upper end surface of the base 1, and a folding device 2 is provided on the upper end of the bottom plate 3.

[0031] The folding device 2 includes a first sliding groove 205. A sliding plate 206 is slidably connected to the front end of the first sliding groove 205. A limit cover 203 is rotatably connected to the upper end of the sliding plate 206. The limit cover 203 is located on one side of the upper end of the base 1. An adhesive plate 201 is provided at the lower end of the limit cover 203 on the upper surface of the base 1. Connecting posts 204 are provided at both ends of the upper surface of the base 1 near the limit cover 203. Connecting blocks 202 are fixedly connected to the upper surfaces of the two connecting posts 204. A connecting block 202 is provided on the lower surface of the two connecting blocks 202 away from the center of the base 1. There are two second electric telescopic rods 209. The upper ends of the two second electric telescopic rods 209 pass through the lower ends of the two connecting blocks 202 and extend into the interior of the two connecting blocks 202. The output ends of the two second electric telescopic rods 209 are fixedly connected to the folding plate 207. The output ends of the two second electric telescopic rods 209 are fixedly connected to the front and rear ends of the upper end of the folding plate 207, respectively. By activating the two second electric telescopic rods 209, the folding plate 207 is raised until the lower end of the folding plate 207 is slightly higher than the upper end of the base plate 3. One of the second electric telescopic rods 209 is set as the main control drive, and the other... The outer folding plate 207 serves as an auxiliary control drive, synchronously extending and retracting through the main control drive. This is a common method in the existing synchronous control system of the second electric telescopic rod 209, which will not be elaborated upon here. The continuous rise of the folding plate 207 raises the area requiring folding, and the limit cover 203 prevents the area of ​​the ton bag / FIBC that does not require folding from rising along with the folding plate 207. Then, the first electric telescopic rod 6 is activated, driving the moving column 7 to move within the moving groove 8, further moving the base plate 3. When the base plate 3 begins to move, it is controlled by… Since the folding plate 207 is only slightly higher than the base plate 3, the limiting cover 203 located at the upper end of the base plate 3 will not move due to the obstruction of the folding plate 207. Therefore, when the inner wall of one side of the first sliding groove 205 provided on the front end face of the base plate 3 contacts the end face of the sliding plate 206 near the center of the base plate 3, it will stop moving. At the same time, the folding plate 207 in contact with the limiting cover 203 will be located at the upper end of the sewing seam 9. The adhesive plate 201 provided on the upper end face of the base plate 3 can effectively prevent the ton bag from sliding upward during the movement of the base plate 3, ensuring that the folding width of the ton bag is consistent.

[0032] like Figure 1 , 2As shown in Figure 3, a flat structure 4 is provided at the upper end of the base plate 3. The flat structure 4 includes two T-shaped slides 406, which pass through the front and rear end faces of the base plate 3 and extend into the interior of the base plate 3. T-shaped sliders 402 are slidably connected to both sides of the interior of the two T-shaped slides 406. Moving plates 401 are fixedly connected to the outer sides of the four T-shaped sliders 402. Grooves 407 are provided at the upper rear end face of the two front moving plates 401 and at the upper front end face of the two rear moving plates 401. Fixing blocks 405 are provided inside the four grooves 407. Springs 403 are fixedly connected to the upper end face of the four fixing blocks 405. The upper end face of the four springs 403 is fixedly connected to the inner wall of the four grooves 407. The two front fixing blocks 405 are fixedly connected to the inner wall of the grooves 407. Each fixed block 405 has a rotatable flattening wheel 404 rotatably connected to the center of its rear end face. The rear ends of the two flattening wheels 404 are rotatably connected to the center of the front ends of the two fixed blocks 405 at the rear end. When preparing to fold the ton bag, the ton bag to be folded is first lifted slightly by the spring 403 inside the moving plate 401 of the flattening structure 4 to ensure that the ton bag can be placed on the upper end of the bottom plate 3. Then, the four T-shaped sliders 402 slide inside the two T-shaped grooves 406, thereby driving the four moving plates 401 to slide, which in turn drives the two flattening wheels 404 to slide on the upper end of the ton bag. Through the continuous sliding of the two flattening wheels 404, the ton bag is flattened, which facilitates the subsequent folding of the ton bag.

[0033] like Figure 1 , 2 As shown in Figure 3, a baffle 5 is fixedly connected to the lower end face of the base 1 away from the folding device 2. A first electric telescopic rod 6 is fixedly connected to the end face of the baffle 5 near the folding device 2. The end face of the first electric telescopic rod 6 away from the folding device 2 passes through the end face of the baffle 5 near the folding device 2 and extends into the interior of the baffle 5, so that the moving column 7 can be moved inside the moving groove 8 by activating the first electric telescopic rod 6.

[0034] like Figure 1 , 2 As shown in Figure 3, the output end of the first electric telescopic rod 6 is fixedly connected to a moving column 7. A moving groove 8 is provided at the center of the lower end face of the base 1. The upper end face of the moving column 7 passes through the lower end face of the moving groove 8 and leads to the lower end face of the base plate 3, which facilitates the movement of the base plate 3 to fold the edges of the ton bag container.

[0035] like Figure 1 , 3 As shown in Figure 4, multiple sewing seams 9 are provided on the upper end face of the base plate 3 near the folding device 2 to facilitate the sewing of ton bag containers.

[0036] like Figure 1 , 3As shown in Figure 4, a sewing groove 208 is provided at the center of the upper end face of the folding plate 207, which facilitates the observation of the flatness and folding width of the ton bag container, and also facilitates the sewing of the ton bag container container.

[0037] Working principle: When preparing to fold the edges of a ton bag, the ton bag to be folded is first slightly lifted by the springs 403 inside the moving plate 401 of the flattening structure 4, ensuring that the ton bag can be placed on the upper surface of the bottom plate 3. Then, the four T-shaped sliders 402 slide inside the two T-shaped grooves 406, thereby driving the four moving plates 401 to slide, which in turn drives the two flattening rollers 404 to slide on the upper end of the ton bag. The continuous sliding of the leveling roller 404 flattens the ton bag, facilitating the subsequent folding of the ton bag. After the ton bag is leveled, the limiting cover 203 is lifted to place the ton bag on the top of the base plate 3. Then, the end of the ton bag that needs to be folded is placed flat on the top of the base plate 3 and the folding plate 207, so that the end of the ton bag that needs to be folded is aligned with the side of the folding plate 207 away from the center of the base plate 3. Then, the limiting cover 203 is lowered to limit and compact the ton bag.

[0038] Then, by activating the two second electric telescopic rods 209, the folding plate 207 is raised until its lower end face is slightly higher than the upper end face of the base plate 3. One of the second electric telescopic rods 209 is set as the main control drive, and the other folding plate 207 as the auxiliary control drive. The main control drive drives the auxiliary control drive to extend and retract synchronously. This is a common method in existing synchronous control systems for second electric telescopic rods 209 and will not be elaborated further here. The continuous rise of the folding plate 207 raises the area requiring folding, and the limiting cover 203 prevents the area of ​​the ton bag / FIBC that does not require folding from rising along with the folding plate 207. Then, the first electric telescopic rod 6 is activated, causing the moving column 7 to move inside the moving groove 8, further moving the base plate 3. When the base plate 3 begins to move, since the folding plate 207 is only slightly higher than the base plate 3, the limiting cover 203 located at the upper end of the base plate 3 will not move due to the obstruction of the folding plate 207. Therefore, when the inner wall of one side of the first sliding groove 205 set on the front end face of the base plate 3 contacts the end face of the sliding plate 206 near the center of the base plate 3, the movement will stop. At the same time, the folding plate 207 in contact with the limiting cover 203 will be located at the upper end of the sewing seam 9. Then, the folding edge of the ton bag can be sewn through the sewing groove 208 and sewing seam 9 set on the upper end of the folding plate 207 and the upper end of the base plate 3. The adhesive plate 201 set on the upper end face of the base plate 3 can effectively prevent the ton bag from sliding upward during the movement of the base plate 3, ensuring that the folding edge width of the ton bag is consistent.

[0039] The equipment also includes an integrated controller. The integrated controller receives signals from various components through input ports. After processing, these signals serve as the basis for control decisions. The integrated controller then uses a control algorithm to process the input signals and generates control outputs according to predetermined rules. Based on the results of the control algorithm, the integrated controller sends signals to the actuators through the output ports. The integrated controller can coordinate the work of various components and continuously monitor the operating status of each component, adjusting the control strategy in a timely manner based on feedback to cope with possible changes or anomalies. This solution is a commonly used technical method in the prior art and will not be elaborated on further here.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
