Description

Technical Field

[0001] This utility model relates to the field of die-cutting guidance and correction technology, specifically to a die-cutting guidance and correction component based on packaging paper boxes. Background Technology

[0002] In the packaging industry, die-cutting of packaging boxes is a crucial step in the production process, as its quality directly affects the appearance, dimensional accuracy, and subsequent performance of the boxes. With the market's increasing demands for higher quality and greater diversity in packaging products, more stringent requirements are being placed on the precision and efficiency of die-cutting of packaging boxes.

[0003] Reference patent (publication number: CN217516297U; publication date: 2022-09-30) discloses a correction device for a cardboard box die-cutting machine, including a transport table, a support fixedly provided at the lower end of the transport table, and correction mechanisms provided on both the front and rear sides of the transport table, with the two correction mechanisms arranged symmetrically. A transmission component is provided on the lower side of the transport table. The correction mechanism includes a cross mounting plate, a T-shaped assembly plate, several transmission rollers, two slide bars, two baffles, and two first springs. Relying on the first springs on both sides of the transport table, the two cross mounting plates and the T-shaped assembly plate can be pressed towards the center of the transport table, so that the several transmission rollers clamp the front and rear sides of the cardboard on the transport table, preventing the cardboard from shifting during transportation, ensuring the die-cutting quality of the subsequent die-cutting machine, improving product production quality, and reducing errors.

[0004] Based on the aforementioned patent, in the traditional die-cutting process of packaging paper boxes, when the paper box moves towards the die-cutting equipment on the conveyor belt, due to the instability of the conveyor belt operation, it is necessary to use a limiting bracket to prevent deviation. However, when adjusting the limiting bracket, the use of gear and rack transmission has backlash, making it difficult to achieve high-precision positioning. At the same time, the lack of an effective fixing mechanism makes it easy for the limiting components to shift during the correction process, resulting in poor correction stability and the inability to continuously and accurately complete the correction task. Furthermore, most traditional correction components can only perform simple linear correction of the paper box, lacking effective means to deal with the multi-angle and multi-directional deviations that may occur during the conveying process. The correction range is narrow, the flexibility is insufficient, and it is difficult to meet the needs of complex production conditions. Therefore, this utility model provides a die-cutting guide and correction component based on packaging paper boxes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a die-cutting guide and correction component based on packaging cartons. It solves the problems of backlash in gear and rack transmission when adjusting the limiting bracket, making it difficult to achieve high-precision positioning. At the same time, the lack of an effective fixing mechanism makes the limiting component prone to displacement during the correction process, resulting in poor correction stability and the inability to continuously and accurately complete the correction task.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting guide and correction assembly for packaging cartons, comprising a support frame, wherein a correction mechanism for die-cutting guidance of the packaging cartons is provided on the support frame, and the correction mechanism includes:

[0007] The limiting component includes a fixed bracket fixed at the lower end of a support frame, a pair of sliding rods fixed to the side wall of the fixed bracket, a U-shaped bracket slidably connected to the outer wall of the sliding rods, a connecting plate connected by a guide component at the upper end of the U-shaped bracket, and a locking component for fixing on the side wall of the U-shaped bracket.

[0008] The adjustment assembly includes a fixing block fixed to one end of the inner wall of the connecting plate, and a limiting bracket connected to the side wall of the fixing block via a pushing assembly. Guide rollers are evenly distributed inside the limiting bracket.

[0009] Preferably, the inner side of the support frame is provided with a conveyor belt for transporting packaging boxes, and one end of the support frame is provided with a die-cutting body.

[0010] Preferably, the fixed bracket is internally rotatably connected to a screw, the U-shaped bracket is threadedly connected to the screw, and the U-shaped bracket can slide on the slide rod via the screw.

[0011] Preferably, the guiding assembly includes a guide bracket fixed to the upper end of a U-shaped bracket, and the connecting plate is located at one end of the guide bracket, and the connecting plate and the guide bracket are fixedly connected.

[0012] Preferably, the locking assembly includes an L-shaped bracket fixed to the side wall of a U-shaped bracket, a second electric push rod is fixed through the interior of the L-shaped bracket, and a clamping ring is fixed to the telescopic end of the second electric push rod. The clamping rings are arranged in two sets distributed on the upper and lower sides of the slide rod.

[0013] Preferably, the jacking assembly includes a first electric push rod rotatably connected to the inner side wall of the connecting plate away from the fixed block via a rotating shaft, the limiting bracket and the fixed block are rotatably connected via a rotating shaft, and the telescopic end of the first electric push rod is rotatably connected via a rotating shaft.

[0014] Beneficial effects

[0015] This invention provides a die-cutting guide and correction component based on packaging cardboard boxes. Compared with the prior art, it has the following advantages:

[0016] Firstly, this invention utilizes a rotating screw inside the fixed bracket. Since the U-shaped bracket is threadedly connected to the screw and slides on the slide rod, the rotation of the screw causes the U-shaped bracket to move horizontally along the slide rod, thereby adjusting the lateral position of the limiting bracket to accommodate the width requirements of different cardboard box specifications, improving the equipment's versatility. Furthermore, the guide roller on the limiting bracket contacts the edge of the cardboard box, and the rolling friction of the roller pushes the cardboard box back to its center position. Compared to the sliding friction of traditional rigid limiting plates, this significantly reduces the risk of wear and scratches on the cardboard box surface, protecting its appearance. Simultaneously, once the U-shaped bracket moves to the predetermined position, the second electric push rod inside the L-shaped bracket is activated. Its telescopic end pushes two sets of clamping rings distributed on the upper and lower sides of the slide rod to clamp the slide rod, fixing the position of the U-shaped bracket through friction. This prevents displacement during subsequent correction processes, ensuring the stability of the correction component and guaranteeing the smooth operation of the correction work.

[0017] Secondly, the first electric push rod on the inner side wall of the starting connecting plate of this utility model, away from the fixed block, has its telescopic end rotatably connected to the limiting bracket via a rotating shaft. The limiting bracket is also rotatably connected to the fixed block via a rotating shaft. As the telescopic end of the first electric push rod extends and retracts, the limiting bracket rotates around the rotating shaft connected to the fixed block, thereby adjusting the angle of the limiting bracket. The tilt angle of the limiting bracket can be adjusted in real time to adapt to the offset of the cardboard box in different directions. Compared with the limiting plate with a fixed angle, it has a wider correction range and greater flexibility. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a die-cutting guide and correction assembly for packaging cartons, including a support frame 1, on which a correction mechanism for die-cutting guide processing of packaging cartons is provided, the correction mechanism including:

[0026] The limiting component includes a fixed bracket 3 fixed at the lower end of the support frame 1, a pair of sliding rods 7 fixed on the side wall of the fixed bracket 3, a U-shaped bracket 301 slidably connected to the outer wall of the sliding rods 7, a connecting plate 303 connected by a guide component at the upper end of the U-shaped bracket 301, and a locking component for fixing on the side wall of the U-shaped bracket 301.

[0027] The adjustment assembly includes a fixing block 4 fixed to one end of the inner wall of the connecting plate 303. The side wall of the fixing block 4 is provided with a limiting bracket 401 connected by a pushing assembly. Guide rollers 402 are evenly distributed inside the limiting bracket 401.

[0028] In a preferred embodiment, a conveyor belt 2 for transporting packaging boxes is provided on the inner side of the support frame 1, and a die-cutting body 201 is provided at one end of the support frame 1. The packaging box is placed on the conveyor belt 2 on the inner side of the support frame 1 and moves towards the die-cutting body 201 with the conveyor belt 2.

[0029] In a preferred embodiment, a screw 6 is rotatably connected inside the fixed bracket 3, and the U-shaped bracket 301 is threadedly connected to the screw 6. The U-shaped bracket 301 can slide on the slide rod 7 via the screw 6. The guide assembly includes a guide bracket 302 fixed at the upper end of the U-shaped bracket 301, and a connecting plate 303 is located at one end of the guide bracket 302. The connecting plate 303 and the guide bracket 302 are fixedly connected. The locking assembly includes an L-shaped bracket 5 fixed to the side wall of the U-shaped bracket 301. A second electric push rod 501 is fixedly fixed inside the L-shaped bracket 5. A clamping ring 502 is fixed at the telescopic end of the second electric push rod 501. The clamping ring 502 is configured as two sets distributed on the upper and lower sides of the slide rod 7.

[0030] By rotating the screw 6 inside the fixed bracket 3, since the U-shaped bracket 301 is threadedly connected to the screw 6 and slides on the slide rod 7, the rotation of the screw 6 will drive the U-shaped bracket 301 to move horizontally along the slide rod 7, thereby adjusting the lateral position of the limiting bracket 401 to adapt to the width requirements of different sized paper boxes and improve the versatility of the equipment.

[0031] Once the U-shaped bracket 301 moves to the predetermined position, the second electric push rod 501 inside the L-shaped bracket 5 is activated. Its telescopic end pushes the clamping ring 502. The two sets of clamping rings are distributed on the upper and lower sides of the slide rod 7 to clamp the slide rod 7. The position of the U-shaped bracket 301 is fixed by friction, preventing displacement during the subsequent correction process, ensuring the stability of the correction component, and ensuring the smooth progress of the correction work.

[0032] In a preferred embodiment, the push assembly includes a first electric push rod 403 rotatably connected to the end of the inner wall of the connecting plate 303 away from the fixed block 4 via a rotating shaft. The limiting bracket 401 is rotatably connected to the fixed block 4 via a rotating shaft, and the telescopic end of the first electric push rod 403 is rotatably connected via a rotating shaft. When the first electric push rod 403 is activated, the telescopic end of the first electric push rod 403 is rotatably connected to the limiting bracket 401 via a rotating shaft. The limiting bracket 401 is also rotatably connected to the fixed block 4 via a rotating shaft. As the telescopic end of the first electric push rod 403 extends and retracts, the limiting bracket 401 rotates around the rotating shaft connected to the fixed block 4, thereby adjusting the angle of the limiting bracket 401. The tilt angle of the limiting bracket 401 can be adjusted in real time to adapt to the offset of the cardboard box in different directions. Compared with a limiting plate with a fixed angle, the correction range is wider and the flexibility is stronger.

[0033] After adjustment, the limiting bracket 401 and the guide rollers 402 evenly distributed inside it guide and correct the packaging boxes on the conveyor belt 2, ensuring that the boxes can accurately enter the die-cutting body 201 at one end of the support frame 1 for die-cutting.

[0034] When the cardboard box shifts, the guide roller 402 on the limiting bracket 401 contacts the edge of the cardboard box. The rolling friction of the roller pushes the cardboard box back to the center position. The rolling friction drives the cardboard box to move. Compared with the sliding friction of the traditional rigid limiting plate, this can greatly reduce the risk of wear and scratches on the surface of the cardboard box and protect the appearance quality of the cardboard box.

[0035] The aforementioned screw is driven by a motor, model N30-050, which is existing technology and will not be elaborated upon further.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, first, according to the specifications of the packaging box, rotate the screw 6 inside the fixed bracket 3. Utilize the threaded connection between the U-shaped bracket 301 and the screw 6, as well as the sliding characteristics of the U-shaped bracket 301 on the slide rod 7, to drive the U-shaped bracket 301 to move horizontally along the slide rod 7 and adjust the lateral position of the limit bracket 401.

[0038] When the U-shaped bracket 301 reaches the predetermined position, the second electric push rod 501 inside the L-shaped bracket 5 is activated, pushing the two sets of clamping rings 502 distributed on the upper and lower sides of the slide rod 7 to clamp the slide rod 7 and fix the U-shaped bracket 301 to prevent displacement; then, the first electric push rod 403 at the end of the inner wall of the connecting plate 303 away from the fixed block 4 is activated, and the limit bracket 401 is rotated around the rotation axis connected to the fixed block 4 by its telescopic end and the rotation axis connection between the limit bracket 401 and the fixed block 4, thereby adjusting the angle of the limit bracket 401;

[0039] Finally, the positioning bracket 401 and its internal guide roller 402, which are adjusted in position and angle, guide and correct the packaging boxes on the conveyor belt 2. When the boxes deviate, the guide roller 402 pushes the boxes back to the center position through rolling friction, ensuring that the boxes accurately enter the die-cutting body 201 for die-cutting.
