Description

Technical Field

[0001] This utility model belongs to the field of cardboard box processing technology, specifically relating to an environmentally friendly cardboard box cutting device. Background Technology

[0002] Cardboard boxes are typically used as wrapping materials for goods or as outer protective layers for items. Depending on the materials used, they can be categorized into corrugated cardboard boxes, single-layer cardboard boxes, etc., and come in various specifications and models. Three-layer and five-layer boxes are commonly used, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. The linerboard and face paper may use materials such as kraft paper or cardboard, while the core paper is usually corrugated paper.

[0003] According to Chinese Patent CN219947427U, an environmentally friendly high-precision cardboard box cutting device is disclosed, including an operating table. Four sets of support legs are symmetrically fixedly installed on the bottom of the operating table. A groove is formed on the surface of the operating table, and a bidirectional threaded rod is rotatably installed inside the groove. During cardboard box cutting, the output shaft of a first drive motor rotates, driving the bidirectional threaded rod to rotate. Through the cooperation of two sets of first sliders, first limit blocks, and first sliding grooves, the two sets of first sliders move relative to each other, thereby moving the fixing components. The extension and retraction of two sets of second electric push rod pistons drive the horizontal plate to move up and down. The horizontal plate drives the spring and pressure plate to move, clamping and fixing the cardboard box. This device can adjust the distance between the two sets of fixing components according to the size of the cardboard box, improving the device's practicality, reducing displacement during cardboard box cutting, and improving the cutting accuracy of the cardboard box.

[0004] However, the aforementioned technical solution has a drawback: while the clamping devices are designed and installed on both sides of the cardboard box material to secure the box and ensure its stability during processing, when cutting the middle of the box, the cutting point often vibrates due to the force of the cutting tool. The amplitude of this vibration increases as the cut widens. This vibration directly leads to a decrease in cutting precision, resulting in uneven cut edges or even deviations, thus affecting the overall quality of the cardboard box and its subsequent performance. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly cardboard box cutting device that can make the cardboard box processing position close to the cutting point, keep the cutting position stable during cutting, and improve cutting accuracy.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An environmentally friendly cardboard box cutting device includes a cutting table. The surface of the cutting table is provided with multiple telescopic rods. The top end of each telescopic rod is fixedly connected to a locking rod. A sliding rod is slidably connected to the surface of the locking rod. A connecting rod is provided above the cutting table. The connecting rod is slidably connected to all the sliding rods. A telescopic blade is slidably connected to the surface of the sliding rods. The connecting rod is fixedly connected to the telescopic blade.

[0008] Preferably, the surface of the cutting table is provided with a slot, the inner cavity of the slot is provided with a lead screw, one end of the lead screw is rotatably connected to the surface of the slot, and the lead screw is threadedly connected to two telescopic rods.

[0009] Preferably, a support frame is fixedly connected to the top of the cutting table, and an adjusting rod is slidably connected to the surface of the support frame, with the bottom end of the adjusting rod penetrating through the surface of the support frame and extending therefrom.

[0010] Preferably, the extension end of the adjusting rod is fixedly connected to a connecting plate, and one end of the plurality of locking rods passes through the surface of the connecting plate and is slidably connected to the connecting plate.

[0011] Preferably, a limiting plate is fixedly connected to the surface of the telescopic rod, and the limiting plate is flush with the edge of the telescopic rod.

[0012] Preferably, a first motor is fixedly connected to the inner cavity of the slot, and one end of the output shaft of the first motor is fixedly connected to the lead screw through a coupling. The threads on the surface of the lead screw are in opposite directions, so that when the lead screw rotates, the two locking rods move closer or further apart.

[0013] Preferably, a second motor is fixedly connected to the surface of the support frame, and a gear is fixedly connected to one end of the output shaft of the second motor via a coupling. A rack is fixedly connected to the surface of the adjusting rod, and the surface of the rack meshes with the gear.

[0014] Preferably, the top of the cutting table is provided with a transparent protective cover, the surface of the cutting table is equipped with a control panel, and the first motor, the second motor and multiple telescopic blades are simultaneously electrically connected to the control panel.

[0015] The technical effects achieved by this utility model are as follows:

[0016] In this invention, the slide bar and the locking bar can press and cover the top of the cardboard fed into the equipment, and a telescopic knife is slidably connected to the surface of the slide bar. When the cardboard is fed into the equipment and ready to be cut, the slide bar can promptly limit the cardboard from the top, ensuring that the cardboard remains flat and stable throughout the cutting process. At the same time, because it is close to the cutting path, when the telescopic knife cuts the cardboard, the slide bar can provide additional compression and fixation to the cardboard near the cutting point, greatly reducing the vibration of the cardboard during the cutting process. Especially when cutting the middle of the cardboard, it can effectively avoid shaking caused by the cardboard not being properly fixed at the cut point, thereby significantly improving the cutting accuracy and stability.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5As shown, an environmentally friendly cardboard box cutting device is described. By activating a first motor and a second motor via a control panel on the cutting table 1, one end of the output shaft of the first motor drives a lead screw 7 to rotate via a coupling. The lead screw 7, through a thread, drives a telescopic rod 2 connected to it to slide within the cavity of a slot 6. The telescopic rod 2 drives a limiting plate 11 connected to it to slide. Meanwhile, one end of the output shaft of the second motor drives a gear 12 to rotate via a coupling. The gear 12, through a meshing rack 13, drives an adjusting rod 9 to slide within the cavity of a support frame 8. The sliding of the adjusting rod 9 causes the connecting plate 10 to rise or fall, which in turn causes the sliding rod 4 to rise or fall, thereby controlling the extension and retraction of the telescopic rod 2. This allows for appropriate adjustments based on the cumulative thickness of the cardboard being cut. This ensures the cardboard enters the equipment smoothly while the limiting plate 11 and connecting plate 10 limit the cardboard, preventing skewing and misalignment, improving cutting accuracy, and enabling the cutting of multiple layers of cardboard, thus increasing cutting efficiency.

[0026] See attached document Figure 2 and Figure 3 There are three telescopic rods 2 arranged in an isosceles triangle on the surface of the cutting table 1. Two of the telescopic rods 2, which are threaded to the lead screw 7, can limit the two sides of the carton. The cardboard enters the equipment through the space between the two telescopic rods 2 for subsequent processing, ensuring the smooth transfer of the cardboard and improving the operating efficiency of the equipment. The last telescopic rod 2 is located at the end of the carton processing path and precisely limits the depth of the cardboard entering the equipment.

[0027] According to the above structure, the surface of the connecting plate 10 is provided with multiple through slots, and the three locking rods 3 slide in the corresponding through slots. The last telescopic rod 2 slides inside the connecting plate 10 through the locking rod 3 to move on the surface of the cutting table 1. When the connecting plate 10 slides up and down, it drives the locking rod 3 connected to it to slide together, so that the telescopic rod 2 component can extend and retract, adjust its extension or retraction length, improve the cumulative thickness of the cardboard cut in a single cut, and significantly improve the cutting efficiency.

[0028] See attached document Figure 3 , Figure 4 and Figure 5The slide bar 4 and the locking rod 3 can press the cardboard fed into the equipment from the top, and the slide bar 4 is slidably connected to the telescopic knife. When the cardboard is fed into the equipment and ready to be cut, the slide bar 4 can limit the cardboard from the top in time, ensuring that the cardboard remains flat and stable throughout the cutting process. At the same time, because it is close to the cutting path, when the telescopic knife cuts the cardboard, the slide bar 4 assembly can provide additional compression and fixation to the cardboard from near the cutting point, which greatly reduces the vibration of the cardboard during the cutting process. Especially when cutting the middle of the cardboard, it can effectively avoid the shaking caused by the cardboard not being properly fixed at the cut point, thereby significantly improving the cutting accuracy and stability.

[0029] Furthermore, the slide bar 4 is slidably connected to the locking bar 3. The locking bars 3 are staggered in height within the inner cavity of the connecting plate 10, allowing the three locking bars 3 to slide simultaneously within the inner cavity of the connecting plate 10. The sliding connection also enables the cutting of different positions on the surface of the cardboard according to the size of the carton, achieving precise cutting of different positions on the surface of the cardboard. This not only meets the cutting needs of cartons of different sizes but also greatly improves the cutting efficiency.

[0030] Furthermore, multiple sliding rods 4 are connected to connecting rods 5, and the electric cylinders connected to the connecting rods 5 can be controlled via the control panel. This allows the connecting rods 5 to drive the telescopic blades to move synchronously on the surface of the sliding rods 4, ensuring that the moving speed and position of all telescopic blades remain consistent during the cutting process. This achieves precise control over the cutting depth of the cardboard and effectively prevents large gaps between the top and bottom covers of the carton caused by inconsistent cutting depths when the cardboard is bound into cartons.

[0031] Based on the above structure, the establishment and cooperation of the locking rod 3, sliding rod 4 and connecting rod 5 enable the telescopic knife to be positioned at any position on the plane, thereby meeting the cutting needs of various complex carton shapes, increasing the applicability of the equipment, improving the utilization rate of the equipment, reducing the skill level requirements of the operators, and making the carton manufacturing process more efficient, accurate and reliable.

[0032] See attached document Figure 3 The threads on the surface of the lead screw 7 rotating inside the slot 6 are opposite, and the two telescopic rods 2 connected to the lead screw 7 are located at opposite ends of the threads. The two telescopic rods 2 are symmetrical at the connection points of opposite ends of the threads, which allows the telescopic rods 2 on both sides to move closer or further away synchronously, so that the center of the cardboard is always on a line. This prevents the cardboard from being cut off due to positioning deviation, which would lead to excessive scrap and increase production costs.

[0033] See attached document Figure 2 and Figure 3The limiting plate 11 is fixedly connected to the surface of the telescopic rod 2. When it is inside the cardboard pushing device, it provides a limiting function, effectively preventing the cardboard from tilting during the feeding process, ensuring that the cardboard can move forward accurately and smoothly according to the predetermined path and direction, thereby ensuring the accuracy and quality of subsequent cutting, and significantly improving the reliability and efficiency of cardboard cutting.

[0034] Reference Figure 5 The telescopic rod 2 can extend and retract on its own, so no specific limitations are made.

[0035] The working principle of this utility model is as follows: the first motor and the second motor are started through the control panel to adjust the position of the corresponding telescopic rod 2 according to the size of the cardboard. Then, the slide rod 4 is moved according to the cutting point position, so that the slide rod 4 drives the telescopic knife to slide on the opposite side of the connecting rod 5 and the locking rod 3. After reaching the appropriate position, it is fixed. Then, the connecting rod 5 is moved according to the cutting depth, so that the telescopic knife slides on the surface of the slide rod 4, and the telescopic knife is moved closer to or away from the locking rod 3. After adjustment, the positions of the slide rod 4 and the connecting rod 5 are fixed to complete the adjustment work.

[0036] Activate all telescopic blades via the control panel and feed the prepared cardboard into the equipment. Place both ends of the cardboard close to the corresponding limit plates 11 and convey it into the equipment. After entering the equipment, the cardboard will contact the activated telescopic blades and be cut by them. When the predetermined cutting depth is reached, the cardboard will be blocked by the corresponding telescopic rod 2 and cannot go any further. Then, the cardboard will be pulled out to complete the cutting.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
