A flip narrow pipeline

Abstract

This utility model discloses a narrow-edge folding production line, including a frame and two conveyor frames symmetrically arranged on the top of the frame. A circulating conveyor chain is movably installed on the inner side of each conveyor frame, and placement fixtures are fixedly installed at equal intervals on the outer side of the circulating conveyor chain. A folding assembly is fixedly installed on the top of each conveyor frame. This narrow-edge folding production line uses a dual-axis motor to drive threaded rods on both sides, causing them to rotate synchronously and push lifting blocks on both sides upwards. A stroke cylinder pushes the left and right folding blocks to the positions of the narrow edges of the cardboard box. When the lifting blocks move the stroke cylinders upwards, the folding blocks contact the narrow edge of the cardboard box from below and push it upwards, causing it to rotate along the folded edge of the cardboard box. This allows for folding operations on the narrow edges of the cardboard box when the outward folding angle is large, making it more flexible in use.

Description

Technical Field

[0001] This utility model relates to the field of paper box folding technology, specifically a narrow edge folding production line. Background Technology

[0002] Paper box forming machines are specialized equipment used in the processing of paper boxes or cardboard to precisely crease, fold, and shape the edges of paper boxes. According to different fold lines of the paper mold, they automatically fold the cardboard into formed paper boxes, realizing automated folding. No manual intervention is required afterward. They have many advantages such as stable operation, excellent folding, simple operation, and high degree of user-friendliness. The core of cardboard narrow edge folding is to precisely fold around the narrow edge of the cardboard to ensure that the edge is neat and the angle meets the standard after folding. The existing patent authorization announcement number CN223173679U discloses an automatic folding device for a paper box forming machine. The folding component can be adjusted up and down by setting the adjustment outer ring in the up and down adjustment mechanism, so as to better perform the folding operation of the paper box. At the same time, it can adapt to the folding operation of paper boxes of different heights. The folding auxiliary bottom plate limits and blocks the side of the paper box that does not need to be folded, thereby protecting the paper box board during the folding operation and avoiding damage to the paper box board during the folding operation. In the aforementioned patent, the bidirectional threaded rod is located in the middle of the inner ring of the adjustment ring. When it is raised or lowered, it will be blocked by the height of the cardboard box. When the narrow side of the cardboard box is turned outward at a large angle and the narrow side is lower than the height of the cardboard box, the folding rod, which can only be moved to the height of the cardboard box, cannot contact the edge of the cardboard box to complete the folding. Its flexibility and applicability are poor. Summary of the Invention

[0003] The purpose of this utility model is to provide a narrow edge turning production line to solve the problem mentioned in the background art that the bidirectional threaded rod is located in the middle position inside the adjusting outer ring, and the height of the paper box will affect the obstruction during the lifting and lowering, resulting in poor flexibility for turning the narrow edge.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a narrow-edge flanging production line, comprising a frame and two conveyor frames symmetrically arranged on the top of the frame. A circulating conveyor chain is movably installed on the inner side of the conveyor frame, and a placement fixture is fixedly installed at equal intervals on the outer side of the circulating conveyor chain. A flanging assembly is fixedly installed on the top of the conveyor frame. The flanging assembly includes two support plates and a top frame respectively fixedly installed on the top of the two conveyor frames. A column is fixedly connected between the two support plates and the top frame. A threaded rod and a guide column connected to the bottom of the top frame are rotatably installed on the top of the two support plates. A dual-axis motor is fixedly installed on the top of the top frame. A transmission rod is fixedly installed on the outer side of the output shafts on both sides of the dual-axis motor. A bevel gear two and a bevel gear one that mesh with each other are fixedly installed on the outer side of the transmission rod and the threaded rod, respectively. A lifting block is movably installed on the outer side of the threaded rod and the guide column. A stroke electric cylinder is fixedly installed inside the lifting block. A flanging block is fixedly installed on the outer side of the stroke electric cylinder located on the inner side wall of the lifting block.

[0005] Preferably, the threaded rod and the guide post are located at the top of the support plate and are staggered front to back. The lifting block is threaded to the outside of the threaded rod and is movably sleeved on the outside of the guide post.

[0006] Preferably, a protective cover is fixedly installed on the top of the top frame, located outside the dual-shaft motor, transmission rod, bevel gear one, and bevel gear two.

[0007] Preferably, the top of the top frame is fixedly connected to a limiting plate arranged symmetrically on the left and right, and the transmission rod passes through the interior of the limiting plate.

[0008] Preferably, the flange block includes a frame, on the side of the frame away from the stroke cylinder, a plurality of first rollers are rotatably mounted, a rotating shaft is rotatably mounted on the upper side of the frame near the stroke cylinder, a folding plate is fixedly mounted on the outside of the rotating shaft, a servo motor connected to the rotating shaft is fixedly mounted on the front side of the frame, and a second roller is rotatably mounted on the inner side of the folding plate away from the rotating shaft.

[0009] Preferably, the plurality of rollers are arranged vertically at equal intervals, and both rollers are made of rubber.

[0010] Preferably, the rotating shaft is arranged in an arc-shaped bend.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By controlling the dual-axis motor to drive the threaded rods on both sides, the threaded rods on both sides rotate synchronously, pushing the lifting blocks on both sides to rise. The stroke cylinder pushes the left and right side flapping blocks to the positions on both sides of the narrow edge of the cardboard box. When the lifting block drives the stroke cylinder to move upward, the flapping block contacts the narrow edge of the cardboard box from the bottom and pushes it upward, so that it rotates along the folded edge of the cardboard box. When the outward folding angle of the narrow edge is large, it can perform the flapping operation on the narrow edge of the cardboard box, making it more flexible to use. 2. When the frame moves to the preset matching height of the cardboard box during the narrow side folding process, the servo motor drives the rotating shaft to rotate. The rotating shaft drives the folding plate to rotate, and the folding plate flips inward into the cardboard box, pushing the narrow side to fold inward. The rotation angle of the folding plate can be controlled by the servo motor, and the narrow side of the cardboard box can be folded at the required angle, which improves flexibility.

[0014] 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.

[0015] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a narrow-edge flanging production line, comprising a frame 1 and two conveyor frames 2 symmetrically arranged on the top of the frame 1. A circulating conveyor chain 3 is movably installed on the inner side of the conveyor frame 2, and a placement fixture 4 is fixedly installed at equal intervals on the outer side of the circulating conveyor chain 3. A flanging assembly 5 is fixedly installed on the top of the conveyor frame 2. The flanging assembly 5 includes two support plates 51 and a top frame 52 respectively fixedly installed on the top of the two conveyor frames 2. A column 53 is fixedly connected between the two support plates 51 and the top frame 52. A threaded rod 54 and a guide post 55 connected to the bottom of the top frame 52 are rotatably installed on the top of the two support plates 51 respectively. A dual-axis motor 56 is fixedly installed on the top of the top frame 52. A transmission rod 57 is fixedly installed on the outer side of the output shafts on both sides of the dual-axis motor 56. Meshing bevel gears are fixedly installed on the outer side of the transmission rod 57 and the threaded rod 54 at their respective ends. Lifting blocks 510 are movably mounted on the outside of bevel gear 59, bevel gear 58, threaded rod 54, and guide post 55. A stroke cylinder 511 is fixedly mounted inside the lifting block 510. A flange block 512 is fixedly mounted on the outside of one end of the inner wall of the lifting block 510. By controlling the dual-axis motor 56, the transmission rods 57 on both sides are driven to rotate. The transmission rods 57 achieve transmission through bevel gear 58, bevel gear 59, and the left and right threaded rods 54, allowing the threaded rods 54 on both sides to rotate synchronously, pushing the lower lifting blocks 510 on both sides upwards. The stroke cylinder 511 pushes the flange blocks 512 on both sides to the narrow edge of the cardboard box. When the lifting block 510 drives the stroke cylinder 511 upwards, the flange blocks 512 contact the narrow edge of the cardboard box from below and push it upwards, causing it to rotate along the folded edge of the cardboard box. This allows for flange operations on the narrow edge of the cardboard box when the outward folding angle is large, making it more flexible to use.

[0016] The placement fixture 4 consists of multiple chain plates installed between the left and right circulating conveyor chains 3, ensuring that each chain plate can pass smoothly at the turning point of the circulating conveyor chain 3, realizing the cyclic use of the placement fixture 4, and then performing a production line-style flanging operation on the cardboard box. Each chain plate is provided with a flange that matches the bottom edge of the cardboard box to hold the cardboard box in place and prevent it from shifting.

[0017] The threaded rod 54 and guide post 55 are located at the top of the support plate 51 and are staggered front to back. The lifting block 510 is threaded to the outside of the threaded rod 54 and is movably sleeved on the outside of the guide post 55. The staggered arrangement can effectively avoid the threaded rod 54 from interfering with the movement of the guide post 55 when the lifting block 510 is being lifted, ensuring that the movement of the lifting block 510 in the vertical direction is more stable and smooth. At the same time, the front and back distribution structure also provides sufficient space for the installation of the stroke electric cylinder 511 and the flanging block 512 on the inner side wall of the lifting block 510, so that when the flanging block 512 performs the flanging operation on the narrow edge of the cardboard box, it will not be restricted by the position of the threaded rod 54 and the guide post 55, further improving the accuracy and reliability of the flanging action.

[0018] The top of the top frame 52 is fixedly equipped with a protective cover 513 located outside the dual-shaft motor 56, transmission rod 57, bevel gear 1 58 and bevel gear 2 59. It is made of aluminum alloy material, which has good rust prevention and wear resistance. It can effectively prevent external dust, moisture and debris generated during production from entering the internal transmission components. The protective cover 513 is detachably connected to the top of the top frame 52 by bolts. When it is necessary to inspect or maintain the internal transmission structure, the protective cover 513 can be quickly removed by simply loosening the bolts. The operation is convenient and provides convenient conditions for the daily maintenance of the equipment.

[0019] The top of the top frame 52 is fixedly connected with symmetrically arranged limiting plates 514. The transmission rod 57 passes through the interior of the limiting plate 514. The gap between the inner wall of the limiting plate 514 and the outer wall of the transmission rod 57 is used to install bearings to reduce friction loss and provide stable support for the axial rotation of the transmission rod 57, preventing radial displacement during high-speed rotation. The bottom of the limiting plate 514 is fixed to the top frame 52 as an integral structure by welding, which can effectively withstand the torque force generated when the transmission rod 57 is running, ensuring the stability of the transmission.

[0020] Please see Figure 1 , Figure 4 and Figure 5The flange block 512 includes a frame 5121. Multiple rollers 5122 are rotatably mounted on the side of the frame 5121 away from the stroke cylinder 511. A rotating shaft 5123 is rotatably mounted above the side of the frame 5121 closest to the stroke cylinder 511. A folding plate 5124 is fixedly mounted on the outside of the rotating shaft 5123. A servo motor 5125 connected to the rotating shaft 5123 is fixedly mounted on the front side of the frame 5121. The folding plate 5124 is located away from the rotating shaft 5123. A rotating roller 5126 is installed on the inner side of the end. When the frame 5121 moves to the preset matching height of the paper box during the narrow side folding process, the servo motor 5125 drives the rotating shaft 5123 to rotate. The rotating shaft 5123 drives the folding plate 5124 to rotate. The folding plate 5124 flips inward into the paper box, pushing the narrow side to fold inward. The rotation angle of the folding plate 5124 can be controlled by the servo motor 5125, and the narrow side of the paper box can be folded at the required angle, which improves flexibility.

[0021] Multiple rotating rollers 5122 are arranged vertically and equidistantly. Both the first rotating roller 5122 and the second rotating roller 5126 are made of rubber, which can form a flexible contact with the edge of the carton during the folding process, avoiding damage or indentation on the carton surface caused by hard contact. The friction of the rubber itself can also enhance the fit with the carton, ensuring that the folding action is accurate and in place, effectively preventing the carton from slipping or shifting during the folding operation, and improving the stability of narrow edge folding and the quality of the finished product.

[0022] The rotating shaft 5123 is designed with an arc-shaped bend, and its curvature is adapted to the rotation trajectory of the folding plate 5124. When the folding plate 5124 is flipped under the drive of the servo motor 5125, the arc-shaped rotating shaft 5123 can provide smoother rotation guidance for the folding plate 5124, enabling the folding plate 5124 to obtain a larger range of flipping angle adjustment, meeting the diverse angle requirements of narrow-edge folding of different specifications of paper boxes, and improving the equipment's adaptability to changes in paper box size.

[0023] Working principle: The circulation conveyor chain 3 in the conveyor frame 2 is controlled to move the placement fixture 4. The cardboard box is placed on the placement fixture 4. The flange on the placement fixture 4 is set to limit the position of the cardboard box. When the cardboard box moves to the bottom of the flange assembly 5, the vision sensor on the flange assembly 5 captures the image of the cardboard box and transmits it to the external PLC control terminal for analysis and detection of the cardboard box position. When the cardboard box reaches the target position, the circulation conveyor chain 3 stops. By controlling the dual-axis motor 56 to drive the transmission rods 57 on both sides to rotate, the transmission rods 57 are driven by the meshing bevel gears 58 and 59 between the threaded rods 54 on the left and right sides, thereby causing the threaded rods 54 on both sides to rotate synchronously, driving the lifting blocks 510 on both sides to slide upward. At the same time, the stroke cylinder 511 pushes the flange blocks 512 on both sides to be located on both sides of the narrow edge of the cardboard box. As the lifting block 510 drives the stroke cylinder 511 to move upward, the flange blocks 512 contact the narrow edge of the cardboard box from below and lift it upward to rotate along the folded edge of the cardboard box. This allows for the flange operation of the narrow edge of the cardboard box when the outward folding angle of the narrow edge is large, making it more flexible to use. When the frame 5121 moves to the predetermined height of the matching paper box, the servo motor 5125 drives the rotating shaft 5123 to rotate, and the rotating shaft 5123 drives the folding plate 5124 to rotate. The folding plate 5124 flips inward towards the inside of the paper box, pushing the narrow edge of the paper box to fold inward. The servo motor 5125 controls the rotation angle of the folding plate 5124 to fold the narrow edge of the paper box as required. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
