Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, specifically a cutting device for cardboard box production with a positioning structure. Background Technology

[0002] In the industrial production process of cardboard boxes, cardboard cutting is a key process that directly determines the dimensional accuracy and appearance quality of the finished cardboard boxes.

[0003] The existing patent document CN217346910U discloses a cutting device for carton production with a positioning structure. This utility model provides a bottom support component, a positioning component, a top sliding component, and a cutting component. Reinforcing crossbars one and two, which are at a 90-degree angle, can improve the stability of the four vertical support rods. The sliding block can slide inside the groove through the slide groove. The sliding block can be used to position the cardboard. The electric guide rail can transmit power to the electric slider, which can drive the fixed box to move, thereby realizing the change of the position of the cutting component. The guide wheel can guide the device, and at the same time, the guide wheel can also press the cardboard firmly on the top of the worktable to prevent the cardboard from tilting during the cutting process, avoid damage to the cardboard during cutting, and improve the safety of the device.

[0004] However, existing cardboard cutting devices with positioning structures are not convenient for dynamic monitoring of positioning accuracy. Due to differences in the material and thickness of different batches of cardboard, the degree of deformation after being subjected to force is also different. Traditional fixed positioning methods cannot dynamically adjust the positioning force and position according to the real-time deformation state of the cardboard. As a result, during the cutting process, the cardboard is prone to displacement and warping due to improper positioning. If the applied pressure is too high, it can easily cause irreversible damage to the cardboard. As a lightweight board made of multi-layer fiber materials, cardboard has a clear threshold for compressive strength. When the pressure applied by the positioning mechanism exceeds the bearing limit of the cardboard fibers, it will directly cause indentations, wrinkles or even cracks on the surface of the cardboard. Especially for corrugated cardboard, excessive pressure will destroy the support of its internal corrugated structure, significantly reducing the compressive strength and cushioning performance of the cardboard. This not only increases raw material waste and production costs, but also affects production efficiency and product quality stability. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a cutting device for carton production with a positioning structure, so as to solve the problem mentioned in the background art that the existing cutting device for carton production with a positioning structure is not convenient for dynamic monitoring of the positioning accuracy of the carton during use.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for carton production with a positioning structure, including a workbench, on which gantry frames are symmetrically welded and fixed on both sides of the upper surface of the workbench, and a support plate is connected between the opposite vertical sections of the two sets of gantry frames, and an electric push rod is installed in the middle of the upper surface of the support plate.

[0009] The transmission end of the electric push rod at the bottom is fixedly connected to the support plate and a push rod. The bottom end of the push rod is fixedly connected to a positioning pressure plate. A rubber anti-slip pad is pasted and fixed to the bottom end of the positioning pressure plate. A preset groove is opened in the middle of the rubber anti-slip pad. A pressure sensor is embedded in the preset groove. A controller is installed on one side of the gantry frame. The pressure sensor is electrically connected to the controller.

[0010] As a further improvement to the above solution, a support beam is provided across the top of the two sets of gantry frames, and a drive motor is installed on one side inside the support beam.

[0011] As a further improvement to the above solution, a transmission screw is fixedly connected to the transmission end of the drive motor, and the end of the transmission screw away from the drive motor is connected to the support beam through a bearing.

[0012] As a further improvement to the above solution, the outer surface of the transmission screw is connected to an internally threaded moving block by a thread, and the internally threaded moving block slides in conjunction with the supporting crossbeam.

[0013] As a further improvement to the above solution, a hydraulic cylinder is installed at the bottom end of the internal thread moving block, and an adjusting rod is fixedly connected to the transmission end of the bottom end of the hydraulic cylinder.

[0014] As a further improvement to the above solution, the end of the adjusting rod away from the hydraulic cylinder is connected to a mounting plate, and a cutting head is provided at the bottom end of the mounting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This carton production cutting device with a positioning structure uses a positioning system consisting of an electric push rod, a push rod, a positioning plate, a rubber anti-slip pad, and a pressure sensor. Before cutting the carton, the electric push rod drives the push rod downward, causing the positioning plate to move downward, making the rubber anti-slip pad in close contact with the cardboard to be cut. The high friction coefficient material of the rubber anti-slip pad effectively prevents the cardboard from sliding. At the same time, the pressure sensor detects the contact pressure in real time and transmits the signal to the controller. When the pressure reaches the preset value, the controller controls the electric push rod to stop running, achieving precise positioning and stable clamping of the cardboard. This positioning method effectively avoids the problem of cardboard displacement or damage due to excessive force caused by insecure fixing during traditional cutting, ensuring the accuracy of cutting dimensions and the neatness of the cut, and significantly improving the production quality of the carton.

[0018] 2. This cutting device for carton production with a positioning structure consists of a drive motor, a transmission screw, an internal thread moving block, a hydraulic cylinder, an adjusting rod, a mounting plate, and a cutting head. The drive motor drives the transmission screw to rotate, and the internal thread moving block moves axially along the support beam through threaded engagement, thereby adjusting the position of the cutting head in the lateral direction. The hydraulic cylinder drives the adjusting rod to rise and fall, which in turn moves the mounting plate and the cutting head up and down to adjust the cutting depth. This dual-degree-of-freedom motion control method allows the cutting head to flexibly cut the cardboard at multiple positions, adapting to the production needs of cartons of different sizes and shapes, and improving the applicability and production efficiency of the equipment.

[0019] 3. This carton production cutting device with a positioning structure features a guide support rod on the upper surface of the positioning plate. The top of the guide support rod passes through a pre-set guide hole in the support plate. During the lifting and lowering of the positioning plate by the electric push rod, the cooperation between the guide support rod and the guide hole provides precise guidance, preventing the positioning plate from tilting or shifting during movement. This ensures that the positioning plate remains parallel to the worktable surface, allowing the rubber anti-slip pad to apply pressure evenly to the cardboard, thus improving the stability and reliability of positioning. Furthermore, the sliding cooperation between the internal threaded moving block inside the support beam and the support beam adopts a limit slider and limit groove structure, effectively preventing the internal threaded moving block from shaking during movement, ensuring the moving accuracy of the cutting head, and further improving the cutting quality.

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.

[0026] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a cutting device for carton production with a positioning structure, including a workbench 1, gantry frames 2 are symmetrically welded and fixed on both sides of the upper surface of the workbench 1, a support plate 3 is connected between the opposite vertical sections of the two sets of gantry frames 2, and an electric push rod 4 is installed in the middle of the upper surface of the support plate 3.

[0027] The transmission end of the electric push rod 4 passes through the support plate 3 and is fixedly connected to the push rod 5. The bottom end of the push rod 5 is fixedly connected to the positioning pressure plate 6. The bottom end of the positioning pressure plate 6 is glued and fixedly attached to the rubber anti-slip pad 7. The middle of the rubber anti-slip pad 7 is provided with a preset groove 8. The preset groove 8 is embedded with a pressure sensor 9. A controller 10 is installed on one side of the gantry frame 2. The pressure sensor 9 is electrically connected to the controller 10.

[0028] When using this carton production cutting device with a positioning structure, first place the cardboard to be cut on the surface of the workbench 1, start the electric push rod 4, its transmission end drives the push rod 5 to move downward, so that the rubber anti-slip pad 7 at the bottom of the positioning pressure plate 6 contacts the surface of the cardboard. The pressure sensor 9 (Honeywell SCL series) inside the rubber anti-slip pad 7 monitors the contact pressure in real time and transmits the signal to the controller 10 (model S7-1200 PLC). When the pressure reaches the preset threshold, the controller 10 controls the electric push rod 4 to stop running. At this time, the positioning pressure plate 6 achieves accurate positioning and uniform clamping of the cardboard through the friction of the rubber anti-slip pad 7 and the feedback mechanism of the pressure sensor 9, avoiding damage to the cardboard due to excessive pressure or displacement due to insecure fixing. Throughout the process, the pressure sensor 9 continuously monitors the positioning pressure, and the controller 10 adjusts the pushing force of the electric push rod 4 in real time to adapt to the material differences of different batches of cardboard, ensuring a balance between positioning accuracy and cardboard integrity, and finally achieving efficient and accurate carton cutting operation.

[0029] A support beam 11 is provided across the top of the two sets of gantry frames 2. A drive motor 12 is installed on one side inside the support beam 11. A drive screw 13 is fixedly connected to the transmission end of the drive motor 12. The end of the drive screw 13 away from the drive motor 12 is connected to the support beam 11 through a bearing. An internal thread moving block 14 is connected to the outer surface of the drive screw 13 through a thread. The internal thread moving block 14 slides with the support beam 11. A hydraulic cylinder 15 is installed at the bottom end of the internal thread moving block 14. An adjusting rod 16 is fixedly connected to the transmission end of the bottom end of the hydraulic cylinder 15. An installation plate 17 is connected to the end of the adjusting rod 16 away from the hydraulic cylinder 15. A cutting head 18 is provided at the bottom end of the installation plate 17. Guide support rods 19 are vertically welded to the upper surface of the positioning pressure plate 6 on both sides of the electric push rod 4. The top end of the guide support rod 19 passes through the pre-set guide hole of the support plate 3.

[0030] After positioning is completed, the drive motor 12 starts, and through the threaded engagement of the transmission screw 13 and the internal thread moving block 14, the internal thread moving block 14 is driven to move laterally along the support beam 11, adjusting the horizontal position of the cutting head 18. At the same time, the hydraulic cylinder 15 drives the adjusting rod 16 to rise and fall, driving the mounting plate 17 and the cutting head 18 to move up and down, precisely controlling the cutting depth. During the cutting process, the engagement of the guide support rod 19 and the guide hole of the support plate 3 ensures that the positioning pressure plate 6 remains vertical and stable during rising and falling, avoiding positioning deviations caused by tilting. The cutting head 18 can be replaced with different types of blades according to the cardboard material and cutting requirements. Through the coordinated movement of the internal thread moving block 14 and the hydraulic cylinder 15, multi-position, high-precision cutting of the cardboard is achieved. After the cutting of one area is completed, the drive motor 12 starts working again, driving the cutting head 18 to move to the next cutting position, repeating the above cutting process.

[0031] Working principle: When using this carton production cutting device with positioning structure, first place the cardboard to be cut on the surface of the workbench 1. Start the electric push rod 4, and its transmission end drives the push rod 5 to move downward, so that the rubber anti-slip pad 7 at the bottom of the positioning pressure plate 6 contacts the surface of the cardboard. The pressure sensor 9 (Honeywell SCL series) inside the rubber anti-slip pad 7 monitors the contact pressure in real time and transmits the signal to the controller 10 (model S7-1200). When the pressure reaches a preset threshold, the controller 10 controls the electric push rod 4 to stop running. At this time, the positioning plate 6 achieves precise positioning and uniform clamping of the cardboard through the friction of the rubber anti-slip pad 7 and the feedback mechanism of the pressure sensor 9, avoiding damage to the cardboard due to excessive pressure or displacement due to insecure fixing. After positioning is completed, the drive motor 12 starts, and through the threaded engagement of the transmission screw 13 and the internal thread moving block 14, it drives the internal thread moving block 14 to move laterally along the support beam 11, adjusting the horizontal position of the cutting head 18. At the same time, the hydraulic cylinder 15 drives the adjusting rod 16 to rise and fall, driving the mounting plate 17 and the cutting head 18 to move up and down, precisely controlling the cutting depth. During the cutting process, the guide support rod 19 and the support plate The guide holes ensure that the positioning plate 6 remains vertically stable during lifting and lowering, avoiding positioning deviations caused by tilting. The cutting head 18 can be replaced with different types of blades according to the cardboard material and cutting requirements. Through the coordinated movement of the internal thread moving block 14 and the hydraulic cylinder 15, multi-position, high-precision cutting of the cardboard is achieved. After the cutting of one area is completed, the drive motor 12 works again, driving the cutting head 18 to move to the next cutting position and repeating the above cutting process. Throughout the process, the pressure sensor 9 continuously monitors the positioning pressure, and the controller 10 adjusts the thrust of the electric push rod 4 in real time to adapt to the material differences of different batches of cardboard, ensuring a balance between positioning accuracy and cardboard integrity, and ultimately achieving efficient and accurate carton cutting operations.
