Description

Technical Field

[0001] This utility model relates to the field of packaging box die-cutting machine technology, and in particular to a packaging box die-cutting machine. Background Technology

[0002] In the packaging box production process, the feeding and positioning accuracy of the die-cutting machine directly affects the product forming quality and production efficiency.

[0003] The positioning mechanism of existing die-cutting equipment is mostly integrated inside the die-cutting unit. After the cardboard enters the equipment, it needs to be positioned and calibrated before the die-cutting operation. This process not only increases the processing time and leads to low overall production efficiency, but also easily affects the positioning accuracy due to internal space limitations, conveying interference and other factors, resulting in problems such as die-cutting deviation and product scrap.

[0004] To address the above problems, we propose a packaging box die-cutting machine. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a packaging box die-cutting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A packaging box die-cutting machine includes a die-cutting machine body and a die-cutting correction mechanism. The die-cutting correction mechanism includes a structural folding plate, a structural plate seat at the bottom of the structural folding plate, sleeves slidably fitted at both ends of the structural plate seat, a first synchronous electric telescopic rod symmetrically fixedly installed on the upper side of the structural plate seat, the output end of the first synchronous electric telescopic rod being fixedly connected to the upper side of the sleeve, a lower connecting seat fixedly connected to the lower side of the sleeve, a guide folding plate fixedly installed on the lower side of the lower connecting seat, a corner groove opened at the inner corner of the guide folding plate, a corner valve plate slidably installed inside the corner groove, and a plurality of pressure sensors fixedly connected between the corner valve plate and the bottom of the corner groove.

[0008] Furthermore, a rotating groove is provided on the inner side of the guide plate, a guide belt is rotatably installed inside the rotating groove, a drive motor is fixedly installed on the upper side of the guide plate, and the output end of the drive motor is fixedly connected to the drive shaft inside the guide belt.

[0009] Furthermore, the outer end of the guide plate is provided with an extended arc edge.

[0010] Furthermore, a number of balls are embedded in the bottom of the guide plate, a sealing ring is sleeved at the embedded port of the balls, a sealing frame is sleeved at the sliding port of the structural plate seat and the sleeve seat, and a lower extension plate is fixedly connected to the lower side of the guide plate.

[0011] Furthermore, the guide belt surface is evenly provided with anti-slip textures.

[0012] Furthermore, U-shaped structural plates are symmetrically fixedly installed on both sides of the structural plate base, and four sets of second synchronous electric telescopic rods are fixedly installed between the U-shaped structural plates and the bottom of the structural folding plate. The structural folding plate is screwed onto the outer wall of the packaging box die-cutting machine body.

[0013] Furthermore, a feed inlet is provided on the right side of the packaging box die-cutting machine body, and a conveyor belt is fixedly installed at the right end of the feed inlet. The guide folding plate is centrally and symmetrically arranged on the upper side of the conveyor belt.

[0014] Furthermore, a PLC controller is fixedly installed on the outer wall of the packaging box die-cutting machine body.

[0015] Compared with related technologies, the packaging box die-cutting machine proposed in this utility model has the following beneficial effects:

[0016] In this invention, a packaging box die-cutting machine utilizes a die-cutting correction mechanism. This mechanism employs symmetrically arranged guide plates on the upper side of the conveyor belt at the inlet to center the cardboard on the conveyor belt. When the cardboard enters the central area of ​​the guide plates, the drive motors on both guide plates are activated, rotating the guide belts on the inner sides of the guide plates. This gradually guides both sides of the cardboard towards the inner corner of the guide plates. When both ends of the cardboard reach the corner valve plates, they contact and abut. When the pressure sensors on the inner sides of the corner valve plates detect pressure signals, it indicates that the cardboard is centered and aligned. Subsequent die-cutting can then be performed directly inside the packaging box die-cutting machine without further positioning, significantly improving the machine's efficiency. Furthermore, this centering alignment process is highly accurate and adaptable to cardboard of different widths. By externalizing the alignment process and completing the symmetrical work before feeding, the processing efficiency of the packaging box die-cutting machine is improved. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1-6 A packaging box die-cutting machine includes a packaging box die-cutting machine body 1 and a die-cutting correction mechanism 5. The die-cutting correction mechanism 5 includes a structural folding plate 51, a structural plate seat 53 is provided at the bottom of the structural folding plate 51, and sleeve seats 55 are slidably sleeved at both ends of the structural plate seat 53. A first synchronous electric telescopic rod 54 is symmetrically fixedly installed on the upper side of the structural plate seat 53. The output end of the first synchronous electric telescopic rod 54 is fixedly connected to the upper side of the sleeve seat 55. A lower connecting seat 56 is fixedly connected to the lower side of the sleeve seat 55. A guide folding plate 57 is fixedly installed on the lower side of the lower connecting seat 56. A corner groove 514 is opened at the inner corner of the guide folding plate 57. A corner valve plate 515 is slidably installed inside the corner groove 514. A plurality of pressure sensors 516 are fixedly connected between the corner valve plate 515 and the bottom of the corner groove 514.

[0026] It should be further noted that the packaging box die-cutting machine body 1 involved in this utility model is a common standardized die-cutting equipment in the printing and packaging industry. Its core structure and working principle have been widely used and disclosed in the industry. This body typically includes a frame, transmission system, die-cutting unit (including core components such as steel blades, printing plates, and die-cutting rollers), PLC control system, waste removal device, and safety protection structure. Its function is to apply pressure to the input cardboard through a preset mold to complete forming operations such as die-cutting and creasing, which conforms to the conventional technical paradigm of die-cutting machines in post-printing processing. In the prior art, such die-cutting machine bodies have achieved automated die-cutting, precise pressure control, and continuous operation capabilities. For example, the disclosed rotary die-cutting machine and flatbed die-cutting machine all have the same core functions as the packaging box die-cutting machine body 1 in this utility model, and their structure and operating logic are common knowledge to those skilled in the art.

[0027] The innovation of this utility model is not in improving the internal structure or die-cutting principle of the packaging box die-cutting machine body 1, but in solving the problem of low efficiency caused by the need for further positioning and correction during the feeding of existing die-cutting machine bodies by adding an external die-cutting correction mechanism 5. The packaging box die-cutting machine body 1 only serves as a basic execution unit, receiving the cardboard after it has been precisely positioned by the die-cutting correction mechanism 5 and completing the die-cutting operation. The signal linkage between the packaging box die-cutting machine body 1 and the die-cutting correction mechanism 5 and the PLC controller 2 is a conventional application of existing automation control technology on known equipment. It does not substantially improve the original structure and function of the die-cutting machine body. Therefore, the technical solution of the packaging box die-cutting machine body 1 has sufficient existing technical support.

[0028] Through the above-described configuration, the structural folding plate 51 provides a stable mounting base for the die-cutting correction mechanism 5. The sliding fit between the structural plate base 53 and the sleeve base 55, combined with the driving action of the first synchronous electric telescopic rod 54, enables the guide folding plates 57 on both sides to move synchronously along the length direction of the structural plate base 53, thereby flexibly adjusting the spacing between the two sets of guide folding plates 57 to adapt to the centering requirements of cardboard of different widths. Meanwhile, the corner valve plate 515 in the corner groove 514, in conjunction with the pressure sensor 516, can accurately detect whether the cardboard has reached the centering position. When both pressure sensors 516 on both sides sense the pressure signal, it can be confirmed that the cardboard is centered and aligned, providing a precise positioning basis for subsequent die-cutting operations.

[0029] In this method, a feed inlet 3 is provided on the right side of the packaging box die-cutting machine body 1, and a conveyor belt 4 is fixedly installed at the right end of the feed inlet 3. The guide folding plate 57 is symmetrically arranged on the upper side of the conveyor belt 4 in the center, and a PLC controller 2 is fixedly installed on the outer wall of the packaging box die-cutting machine body 1.

[0030] Through the above-mentioned setup, the cooperation between the feed inlet 3 and the conveyor belt 4 achieves stable conveying of the cardboard. The guide folding plates 57 are symmetrically distributed in the center on the upper side of the conveyor belt, ensuring that the cardboard can contact the guide structures on both sides simultaneously when it enters. The PLC controller 2 plays a core control role, receiving signals from the pressure sensor 516 and synchronously controlling the operation of the first synchronous electric telescopic rod 54, the drive motor 511, and the packaging box die-cutting machine body 1, realizing the automated connection between the correction positioning and the die-cutting operation, and reducing manual intervention.

[0031] In this method, a rotating groove 59 is provided on the inner side of the guide plate 57, and a guide belt 510 is rotatably installed inside the rotating groove 59. A drive motor 511 is fixedly installed on the upper side of the guide plate 57, and the output end of the drive motor 511 is fixedly connected to the internal drive shaft of the guide belt 510. Anti-slip textures are evenly distributed on the surface of the guide belt 510.

[0032] With the above-described configuration, the rotating slot 59 provides installation space for the guide belt 510. The drive motor 511 can drive the guide belt 510 to rotate stably. When the cardboard enters the middle area of ​​the guide fold plate 57, the rotating guide belt 510 can generate a uniform guiding force on both sides of the cardboard, guiding the cardboard smoothly towards the inner fold of the guide fold plate 57. The anti-slip texture on the surface of the guide belt 510 increases the friction with the cardboard contact surface, preventing slippage during the guiding process and further improving the stability and accuracy of centering alignment.

[0033] In this configuration, the outer end of the guide plate 57 is provided with an extended arc edge 58.

[0034] With the above-mentioned setup, the outer arc edge 58 of the outer end of the guide folding plate 57 adopts an arc transition design, which can guide the cardboard smoothly into the area between the two sets of guide folding plates 57, avoid the cardboard edge from colliding or getting stuck with the outer end of the guide folding plate 57, ensure the continuity of the cardboard conveying process, and reduce the impact of feeding resistance on positioning accuracy.

[0035] In this method, a number of balls 512 are embedded at the bottom of the guide plate 57, and a sealing ring is fitted at the embedded port of the balls 512. A sealing frame is fitted at the sliding port of the structural plate seat 53 and the sleeve seat 55. A lower extension plate 513 is fixedly connected to the lower side of the guide plate 57.

[0036] With the above-mentioned configuration, the ball bearings 512 at the bottom of the guide folding plate 57 can reduce the contact friction when the guide folding plate 57 is lowered onto the upper surface of the conveyor belt 4. During the operation of the conveyor belt 4, the bottom of the guide folding plate 57 will not be scraped. The sealing frame can prevent dust and debris from entering the sliding port of the sleeve 55, ensuring the sliding flexibility and service life of the components. The lower extension plate 513 can reduce the gap when the bottom of the guide folding plate 57 is lowered onto the conveyor belt 4, avoiding the jamming of thin packaging cardboard.

[0037] In this method, U-shaped structural plates 52 are symmetrically fixedly installed on both sides of the structural plate base 53. Four sets of second synchronous electric telescopic rods 517 are fixedly installed between the U-shaped structural plates 52 and the bottom of the structural folding plate 51. The structural folding plate 51 is screwed onto the outer wall of the packaging box die-cutting machine body 1.

[0038] With the above-described configuration, the second synchronous electric telescopic rod 517 is used to change the distance between the guide folding plate 57 and the conveyor belt 4. When placed on the upper side of the conveyor belt 4, it aligns the packaging cardboard in the center. After the centering alignment is completed, the second synchronous electric telescopic rod 517 lifts the guide folding plate 57. Under the conveying action of the conveyor belt 4, the aligned paper passes through the bottom of the guide folding plate 57 and enters the packaging box die-cutting machine. Subsequently, the guide folding plate 57 is lowered to the upper side of the conveyor belt 4 under the extension action of the second synchronous electric telescopic rod 517 to continue the centering alignment work.

[0039] It should be noted that a photoelectric sensor is installed on the inner side of the guide plate (to sense the conveying position of the packaging cardboard conveyed on the conveyor belt 4). The photoelectric sensor is a common electrical component in existing automated conveying equipment, and will not be described in detail here.

[0040] The working principle of the packaging box die-cutting machine provided by this utility model is as follows:

[0041] Before operation, according to the width specifications of the cardboard to be processed, the PLC controller 2 issues a command to control the first synchronous electric telescopic rod 54 to drive the sleeve 55 to slide along the structural plate seat 53, adjusting the distance between the two sets of guide folding plates 57 to the appropriate size; at the same time, the second synchronous electric telescopic rod 517 is started, driving the structural plate seat 53 and the guide folding plate 57 to move down as a whole, so that the ball bearings 512 at the bottom of the guide folding plate 57 are in contact with the upper surface of the conveyor belt 4, and the lower extension plate 513 forms an appropriate gap with the conveyor belt 4 to avoid the thin cardboard getting stuck. When the cardboard is conveyed to the feed port 3 by the conveyor belt 4, the photoelectric sensor on the inner side of the guide folding plate 57 detects the position signal of the cardboard and transmits it to the PLC controller 2. The PLC controller 2 synchronously starts the drive motor 511, driving the guide belt 510 in the rotating groove 59 to rotate. With the help of the anti-slip texture on the surface of the guide belt 510 to enhance the friction with both sides of the cardboard, and with the guiding effect of the outer arc edge 58 at the outer end of the guide folding plate 57, the cardboard is pushed smoothly to the inner folding corner of the guide folding plate 57.

[0042] When the two ends of the cardboard abut against the corner valve plates 515 in the corner grooves 514 on both sides, the corner valve plates 515 are pressed and slide into the corner grooves 514, triggering the pressure sensor 516 to generate a pressure signal. This signal, together with the detection signal of the photoelectric sensor, is fed back to the PLC controller 2 to confirm that the cardboard has been accurately centered and aligned. Then, the PLC controller 2 immediately controls the drive motor 511 to stop running and simultaneously commands the second synchronous electric telescopic rod 517 to extend, driving the guide folding plate 57 to lift up as a whole, making way for the cardboard to be conveyed. The conveyor belt 4 continues to run, smoothly feeding the centered cardboard into the feed port 3 of the packaging box die-cutting machine body 1. The PLC controller 2 simultaneously sends a die-cutting start signal to the packaging box die-cutting machine body 1. Since the cardboard has been accurately positioned externally, the packaging box die-cutting machine body 1 does not need internal secondary positioning and directly starts the die-cutting unit to complete the operation. During single-sheet die-cutting, the second synchronous electric telescopic rod 517 drives the guide folding plate 57 to return to the upper side of the conveyor belt 4, and the first synchronous electric telescopic rod 54 can adjust the spacing according to the specifications of the next sheet of paperboard. The photoelectric sensor continuously detects the position of the subsequent paperboard and repeats the above correction process to achieve continuous and high-precision processing.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
