Description

Technical Field

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

[0002] To produce carton sets, a die-cutting machine symmetrically cuts long rectangular strips of waste material from the front and rear of the cardboard near the middle. The die-cut cardboard is then easily folded into carton sets. An existing die-cutting machine for producing cartons, with publication number CN220883539U, uses a motor-driven conveyor to automatically feed the cardboard to the worktable and precisely position it using a sliding limiter. Subsequently, a cylinder drives the cutter assembly downwards, where a clamping device first contacts and clamps the cardboard. Then, the cutting blade completes the punching operation. After punching, the cutter assembly rises, and the clamping device, under the action of a tension spring... Once the reset is released, the waste generated during die-cutting is simultaneously drawn away and centrally stored by the negative pressure collection device located below through the gap in the worktable support. However, this design still has shortcomings in practice: First, its negative pressure collection device is mainly for powdery and fine debris. For long strips and large rectangular waste generated during die-cutting of boxes, it is easy to cause blockage in the gap in the support, affecting collection efficiency and requiring frequent machine shutdowns for cleaning. Second, although the device automates the die-cutting process, it lacks an automatic unloading mechanism for finished products. After die-cutting, the processed cardboard remains on the worktable. Utility Model Content

[0003] The purpose of this invention is to provide a die-cutting machine for producing cardboard boxes in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A die-cutting machine for producing cardboard boxes includes a support mechanism. The support mechanism includes a collection box with a door hinged to one side. A first sliding rod is vertically fixed to the collection box, and the first sliding rods are symmetrically arranged. A cylinder support plate is fixed to the top of each first sliding rod. A die-cutting mechanism is provided on the cylinder support plate. The die-cutting mechanism includes a cylinder, and the piston rod of the cylinder is connected downwards to an upper template. A die-cutting assembly and a limiting assembly are installed at the bottom of the upper template.

The lower end of the push rod is connected to a top plate, and the push rod is positioned above the upper template. A first spring is fitted between the upper template and the top plate; the limiting assembly includes a second slide rod passing through both sides of the upper template, the lower end of the second slide rod is connected to a limiting plate, and a second spring is fitted on the second slide rod between the upper template and the limiting plate; a lower mold base is provided below the upper template, and a conveying mechanism is provided at the bottom of the lower mold base; the conveying mechanism includes a symmetrically arranged spiral screw and a third slide rod; a threaded seat is threadedly connected to the spiral screw, and a slider is slidably connected to the third slide rod; both the threaded seat and the slider are fixedly connected to the bottom surface of the lower mold base, and a control cabinet is fixed to the side of the collection box.

[0006] Further configuration: The upper template is slidably connected to the first slide bar, and the upper template is fixedly connected to the tool mounting plate.

[0007] Further details: The front and rear of the tool mounting plate are symmetrically provided with grooves on the left and right sides near the middle. The tool is fixedly connected around the groove of the tool mounting plate. The top rod is slidably connected to the upper template and passes through the groove of the tool mounting plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By setting up a die-cutting mechanism and a conveying mechanism, the cylinder of the die-cutting mechanism drives the upper template to descend smoothly along the first slide bar. The limiting plate of the limiting component first contacts and presses the cardboard, compressing the second spring to fix the material. Then, the top plate contacts the cardboard, the upper template continues to descend, the top plate retracts against the resistance of the first spring, and the cutter completes the punching. After punching, the first spring releases energy, pushing the top plate downward to perform forced demolding, effectively solving the problem of finished products or waste materials "sticking to the mold". The stepper motor of the conveying mechanism drives the screw to rotate, causing the threaded seat to move the lower mold base. At the same time, the slider slides along the third slide bar, realizing the rapid, precise and stable reciprocating motion of the lower mold base between the die-cutting station and the feeding and discharging station. The waste generated by the die-cutting falls into the collection box through the groove on the lower mold base for easy centralized cleaning. This utility model can efficiently and automatically complete the die-cutting of cardboard and waste collection, saving a lot of operation time and improving production efficiency and product quality.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-6 As shown, a die-cutting machine for producing cartons includes a support mechanism, which includes a collection box 11. A box door 12 is hinged to one side of the collection box 11, and a first slide rod 13 is fixedly connected to the collection box 11. The first slide rods 13 are symmetrically arranged, and a cylinder support plate 14 is fixedly connected to the first slide rods 13. A die-cutting mechanism is provided on the cylinder support plate 14, and a conveying mechanism is provided on the collection box 11.

[0025] In this embodiment: the die-cutting mechanism includes a cylinder 21, the piston rod of which extends downward and is fixedly connected to an upper template 22. This upper template 22 is slidably connected to the first slide rod 13. The upper template 22 integrates a die-cutting assembly and a limiting assembly. The die-cutting assembly consists of a tool mounting plate 231 fixed to the bottom of the upper template 22 and a tool 232 mounted on its bottom. The tool mounting plate 231 has symmetrical grooves on its front and rear sides near the middle. At the same time, a push rod 233 is vertically inserted through the upper template 22. The push rod 233 slides with the upper template 22 and passes through the groove of the tool mounting plate 231. The upper end of the die-cutting mechanism is fixedly connected to a top plate 234, and a first spring 235 is sleeved on the top rod 233 between the upper template 22 and the top plate 234. The shape of the top plate 234 matches the groove shape of the cutter mounting plate 231. The limiting assembly includes at least two second sliding rods 241 passing through both sides of the upper template 22. The second sliding rods 241 are slidably connected to the upper template 22, and a limiting plate 242 is fixedly connected to their lower ends. A second spring 243 is sleeved on the second sliding rods 241 between the upper template 22 and the limiting plate 242. Below the entire die-cutting mechanism, above the top opening of the collection box 11, a lower die base is provided. 25. The lower die base 25 has symmetrical grooves on the left and right sides near the middle of the front and rear parts; the lower die base 25 is equipped with limit blocks. The die-cutting machine cuts a long rectangular strip of waste material symmetrically from the left and right sides near the middle of the front and rear parts of the cardboard. The die-cut cardboard is easy to fold into a set box. First, the cardboard to be processed is placed in the limit block of the lower die base 25 for initial limiting. The cylinder 21 drives the upper template 22 to descend smoothly along the first slide rod 13. First, the limit plate 242 in the limiting assembly contacts and presses the cardboard, and the second spring 243 inside is compressed. This not only pre-fixes the material, but also provides a certain pressure through the deformation of the spring. The die-cutting pressure is controlled and overload protection is provided. Subsequently, the top plate 234 contacts the cardboard first. The upper template 22 continues to descend, forcing the top plate 234 to overcome the resistance of the first spring 235 and retract relatively into the groove of the cutter mounting plate 231. During this process, the cutter 232 completes the punching, while the top plate 234 remains pressed against the cardboard surface under the pressure of the first spring 235. After the punching is completed, the first spring 235 releases energy, pushing the top plate 234 downward to perform forced demolding. The upper template 22 rises, and the waste material cut by the cutter 232 falls into the collection box 11 through the groove of the lower mold base 25, effectively solving the core problem of waste collection.

[0026] In this embodiment, the conveying mechanism includes a helical screw 31 and a third slide rod 35 symmetrically arranged below the lower mold base 25. The helical screw 31 is rotatably connected to the collection box 11, and a threaded seat 32 is threaded onto it; the third slide rod 35 is fixedly connected to the collection box 11, and a slider 36 is slidably connected onto it. The threaded seat 32 and the slider 36 are together fixedly connected to the bottom surface of the lower mold base 25, thereby achieving stable movement of the lower mold base 25. One end of the screw 31 is driven by a stepper motor 33, and the output shafts of the two are fixedly connected. The control center of the entire equipment is the control cabinet 34 fixed to the side of the collection box 11. The precise positioning of the conveying mechanism is controlled by the controller in the control cabinet 34 by sending a specific number of electrical pulses to the stepper motor driver to control the stepper motor 33 to rotate at a set angle. (The above control principle is existing technology and will not be described in detail here.) The stepper motor 33 drives the screw 31 to rotate, and the threaded seat 32 converts the rotational motion into precise linear motion. To ensure smooth operation, the slider 36 and the threaded seat 32 are fixed together to the bottom of the lower die holder 25. During operation, the slider 36 slides along the third slide bar 35. The conveying mechanism realizes the rapid, precise and stable reciprocating motion of the lower die holder 25 between the feeding station, the die-cutting station and the unloading station. When it is in the die-cutting station, the die-cutting mechanism performs processing. After completion, the conveying mechanism carries the lower die holder 25, which is die-cut finished paperboard, to the unloading station for unloading. This process is the key to realizing automated continuous production.

[0027] The working principle and usage process of this utility model are as follows: During operation, the cardboard to be processed is placed in the limiting block of the lower die base 25. The controller in the control cabinet 34 sends a specific number of electrical pulses to the stepper motor driver to control the stepper motor 33 to rotate at a set angle, driving the screw 31 to rotate, so that the threaded seat 32 connected to it drives the lower die base 25 to move. At the same time, the slider 36 fixed to the bottom of the lower die base 25 slides along the third slide bar 35. The two work together to realize the precise and stable reciprocating motion of the lower die base 25 between the die-cutting station and the feeding and unloading station. After the cardboard is in place, the die-cutting mechanism is activated: the cylinder 21 fixed on the cylinder support plate 14 drives the upper template 22 to move down along the first slide bar 13. The limiting plate 242 of the limiting component first contacts the cardboard and compresses the second spring 243 to press the cardboard. Subsequently, the top plate 234 contacts the cardboard. As the upper template 22 continues to move down, the top plate 234 overcomes the resistance of the first spring 235 and retracts into the groove of the cutter mounting plate 231. At the same time, the cutter 232 installed at the bottom of the cutter mounting plate 231 completes the punching of the cardboard. After punching, the first spring 235 releases energy and pushes the top plate 234 to move downward, performing forced demolding. The upper template 22 rises, and the cut waste falls into the collection box 11 below through the matching groove on the lower die base 25. The conveying mechanism carries the lower die base 25 carrying the die-cut cardboard to the unloading station for unloading. After the waste collection is full, the box door 12 can be opened for cleaning.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
