Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, specifically a folding machine for packaging box processing. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated boxes, etc., or by product name, such as mooncake boxes, tea boxes, goji berry boxes, candy boxes, exquisite gift boxes, local specialty product boxes, wine boxes, chocolate boxes, food, medicine, and health product boxes, food packaging boxes, tea packaging boxes, stationery boxes, etc. The functions of packaging boxes include ensuring product safety during transportation and enhancing product quality. Packaging boxes require edge folding during production and processing.

[0003] In the prior art, such as patent number CN222473509U, a folding device for packaging box processing is disclosed, which can conveniently press the upper two sides of the cardboard, and then move and squeeze the upper end of the cardboard body through the pressure roller, thereby improving the crease of the cardboard body and avoiding damage to the cardboard body, improving the folding effect of the cardboard body, and improving the processing effect of the packaging box.

[0004] However, in the aforementioned patent, the rotation of the lead screw drives the moving block to move the pressure roller laterally. This requires the pressure roller to move from one end of the lead screw to the other end to squeeze and improve the creases of the cardboard body. This stroke is relatively long, which can easily reduce its processing efficiency when used for a long time. At the same time, by placing the cardboard on the support plate and pressing it with the pressure plate, it is not accurate enough to rely solely on manual judgment based on experience to determine whether the placement is tilted. Utility Model Content

[0005] The purpose of this utility model is to provide a folding machine for packaging box processing, so as to solve the problems mentioned in the background art, which require the pressure roller to move from one end of the lead screw to the other end to squeeze and improve the fold of the cardboard body. This stroke is relatively long and can easily reduce its processing efficiency when used for a long time. At the same time, it is not accurate enough to place the cardboard on the support plate and press it with the pressure plate, relying solely on manual judgment based on experience to determine whether the placement is tilted.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a folding machine for packaging box processing, comprising a support plate and a mounting frame fixedly connected to the top of the support plate, a pressing cylinder fixedly mounted on the top of the inner side of the support plate, a pressing component fixedly mounted on the bottom of the pressing cylinder, a folding component fixedly mounted on the front side of the pressing component, an installation groove provided on the top of the support plate, and a calibration component movably mounted inside the installation groove;

[0007] The folding and pressing assembly includes a connecting frame fixedly connected to the front side of the pressing assembly. An inclined side rod is fixedly connected to the front side of the connecting frame. A rotating shaft is movably installed on the inner side of the side rod. A roller is movably installed on the outer side of the rotating shaft. A top frame is fixedly installed on the top of the side rod. A folding and pressing cylinder is fixedly installed on the outer side of the top frame. A pressure plate is movably connected to the inner side of the folding and pressing cylinder.

[0008] Preferably, the pressure plate and the front corner of the support plate are inclined.

[0009] Preferably, a slider is fixedly connected to the outside of the pressure plate, and a second buffer spring is movably engaged inside the pressure cylinder. The slider is movably engaged inside the pressure cylinder and located outside the second buffer spring.

[0010] Preferably, the outer side of the pressure plate is fixedly connected with symmetrical guide posts, which are movably engaged inside the top frame.

[0011] Preferably, the calibration component includes a sliding seat that is engaged in the mounting groove, a stop block is fixedly installed on the top of the sliding seat, and grooves are provided on both the left and right sides of the sliding seat. Rollers located in the mounting groove are movably installed outside the grooves.

[0012] Preferably, the abutment block is positioned higher than the support plate.

[0013] Preferably, the clamping assembly includes a connecting plate fixedly connected to the bottom of the clamping cylinder, with sliding columns movably engaged at the four corners inside the connecting plate, a pressure plate fixedly installed at the bottom of the sliding column, and a buffer spring movably sleeved on the outside of the sliding column between the connecting plate and the pressure plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In use, the rollers rotate under the support of the shaft to bend the cardboard downward along the front edge of its support plate. The pressure plate is pushed down by the folding cylinder. The oblique pressure plate squeezes the cardboard at the folding edge to fold and intensify the indentation, thereby folding the edge of the packaging box cardboard. The folding cylinder has a short stroke and fast pressing to improve its processing efficiency.

[0016] 2. When the cardboard needs to be aligned during processing, the sliding seat will slide along the mounting groove by pressing the back of the cardboard against the front of the abutment block to accurately position the cardboard and prevent it from tilting to the left or right, ensuring that the folding of the packaging box can be carried out accurately.

[0023] 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.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a folding machine for packaging box processing, including a support plate 1 and a mounting frame 2 fixedly connected to the top of the support plate 1. A pressing cylinder 3 is fixedly installed on the top of the inner side of the support plate 1, a pressing component 4 is fixedly installed on the bottom of the pressing cylinder 3, a folding component 5 is fixedly installed on the front side of the pressing component 4, and an installation groove 6 is opened on the top of the support plate 1. A calibration component 7 is movably installed inside the installation groove 6.

[0025] The folding and pressing assembly 5 includes a connecting frame 51 fixedly connected to the front side of the pressing assembly 4. An inclined side rod 52 is fixedly connected to the front side of the connecting frame 51. A rotating shaft 53 is movably mounted on the inner side of the side rod 52. A roller 54 is movably mounted on the outer side of the rotating shaft 53. A top frame 55 is fixedly mounted on the top of the side rod 52. A folding and pressing cylinder 56 is fixedly mounted on the outer side of the top frame 55. A pressure plate 59 is movably connected to the inner side of the folding and pressing cylinder 56.

[0026] In use, the roller 54, supported by the rotating shaft 53, rotates to bend the cardboard downwards along the leading edge of its support plate 1. The pressing cylinder 56 pushes the pressure plate 59 downwards, and the angled pressure plate 59 presses against the folded edge of the cardboard to create a fold, intensifying the indentation and thus folding the edge of the packaging box cardboard. The pressing cylinder 56 has a short stroke and rapid pressing, improving processing efficiency.

[0027] The pressing plate 59 is angled relative to the front corner of the support plate 1. This angled setting allows the pressing plate 59 to better conform to the angle of the cardboard fold, ensuring the accuracy and depth of the indentation and thus improving the folding effect. Simultaneously, the angled pressing plate 59 reduces frictional resistance with the cardboard during the pressing process, making the pressing process smoother and further improving processing efficiency.

[0028] A slider 58 is fixedly connected to the outside of the pressing plate 59. A second buffer spring 57 is movably engaged inside the pressing cylinder 56. The slider 58 is movably engaged inside the pressing cylinder 56 and positioned outside the second buffer spring 57. When the pressing plate 59 performs the pressing action, the slider 58 slides inside the pressing cylinder 56, compressing the second buffer spring 57, which plays a crucial buffering role. This adjusts the downward pressure of the pressing plate 59 to a certain extent, making the indentation formation more uniform and moderate, and further improving the folding effect.

[0029] The outer side of the pressing tablet 59 is fixedly connected with symmetrical guide posts 510. The guide posts 510 are movably engaged inside the top frame 55. The setting of the guide posts 510 can ensure that the pressing tablet 59 maintains a stable movement trajectory during the pressing process, and avoid the pressing tablet 59 from shifting or shaking due to uneven force, thereby further ensuring the accuracy and depth of the indentation.

[0030] Please see Figure 4 and Figure 5 The alignment component 7 includes a sliding seat 71 that is engaged within the mounting groove 6. A stop block 72 is fixedly mounted on the top of the sliding seat 71. Grooves 73 are provided on both the left and right sides of the sliding seat 71. Rollers 74 located within the mounting groove 6 are movably mounted on the outside of the grooves 73. When the cardboard needs to be aligned during processing, the sliding seat 71 slides along the mounting groove 6 by pressing the rear side of the cardboard against the stop block 72, thereby accurately positioning the cardboard and preventing it from tilting to the left or right, ensuring that the folding of the packaging box can be performed accurately.

[0031] The abutment block 72 is set higher than the support plate 1. When the cardboard is pushed to the abutment block 72, the rear edge of the cardboard can be effectively supported, which improves the accuracy of the cardboard position calibration.

[0032] Please see Figure 2The clamping assembly 4 includes a connecting plate 41 fixedly connected to the bottom of the clamping cylinder 3. The four corners inside the connecting plate 41 are movably engaged with sliding columns 42. The bottom of the sliding column 42 is fixedly installed with a pressure plate 44. The outside of the sliding column 42 is movably sleeved with a buffer spring 43 located between the connecting plate 41 and the pressure plate 44.

[0033] The buffer spring 43 provides a certain buffering effect during the pressing of the cardboard by the pressure plate 44, preventing the pressure plate 44 from directly contacting the cardboard and thus preventing the cardboard from being damaged. It also makes the pressing process more stable.

[0034] Working principle: By placing the cardboard on the support plate 1 and having its rear side abut against the front side of the abutment block 72, the cardboard is pushed to make the roller 74 on the side of the sliding seat 71 roll within the mounting groove 6, causing the sliding seat 71 to move backward along the mounting groove 6, so that the folded edge of the cardboard coincides with the front edge of the support plate 1. Since the abutment block 72 is set in parallel and the sliding seat 71 has a certain weight, the rear side of the cardboard abuts against the abutment block 72 to ensure that the cardboard is placed parallel on the support plate 1. By controlling the pressing cylinder 3 to drive the connecting plate 41 to move downward, the pressure plate 44 presses on the cardboard. The pressure plate 44 pushes the sliding column 42 upward to compress the buffer spring 43 to provide cushioning. The pressure plate 44 is positioned inside the abutment block 72 to avoid it. The rotating shaft 53 moves downwards to contact the folded edge of the cardboard, pressing it downwards and bending it along the front edge of the support plate 1. The folding cylinder 56 controls the guide column 510 to move inwards, pressing obliquely against the folded edge of the cardboard and the front edge of the support plate 1. The pressure plate 59 pushes the slider 58 along the folding cylinder 56 to compress the buffer spring 57, thus squeezing the folded edge of the cardboard and increasing the crease. Then, the compression cylinder 3 releases the pressure on the cardboard and pulls back the alignment assembly 7 for reuse.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] 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.
