Description

Technical Field

[0001] The invention belongs to the technical field of cardboard trimming, in particular to a cardboard trimming system with high-quality trimming. Background Art

[0002] As a basic material widely used in packaging, construction, printing and other fields, the quality of cardboard trimming directly affects the overall appearance, physical properties and subsequent processing efficiency of the product. As the market's requirements for cardboard quality continue to increase, a high-quality cardboard trimming system is particularly important.

[0003] The edges of the cardboard may become burred, uneven or irregular during the production process. By trimming, these defects can be removed, making the edges of the cardboard neater and more beautiful, further consolidating the edge structure of the cardboard and enhancing its overall stability. During the trimming process, the internal structure of the cardboard will also affect the trimming quality. The internal structure of the cardboard is mainly composed of fibers, which are interwoven with each other during the papermaking process to form countless pores, making the cardboard hydrophilic. The bonding force between the fibers and the arrangement of the fibers will affect the strength and cutting quality of the cardboard. When the moisture content is too high or too low, the bonding force between the fibers will change, causing the tool to encounter greater resistance or instability during the cutting process. This may cause problems such as burrs, cracks or unevenness on the cut edges. The existing trimming system lacks intelligent monitoring and feedback mechanisms, and cannot detect the trimming quality in real time and adjust parameters in time.

[0004] In view of the problems existing in the prior art, there is an urgent need for a trimming system that can detect moisture content changes in real time and adjust process parameters in a timely manner according to feedback results, so as to improve the cardboard cutting quality and improve the overall quality of the product. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a high-quality cardboard trimming system that can detect the moisture content changes at the cutting position in real time, automatically adjust the process parameters according to the real-time feedback results, and ensure the stability and consistency of the cutting quality.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a high-quality cardboard trimming system comprises an operating table; a clamping module, a cutting module, a detection module and a control module are arranged on the operating table; the clamping module is used to fix the cardboard; the cutting module comprises a tool and a first moving component; the first moving component is used to assist the tool to complete the shearing movement; a humidity regulating component is arranged on the tool; the humidity regulating component is used to centrally regulate the humidity of the cardboard cutting position; the detection module is used to detect the moisture content of the cutting position; the control module is used to control the operation of the humidity regulating component based on the moisture content of the cutting position.

[0007] The above scheme has the following beneficial effects:

[0008] 1. This solution can ensure that the cardboard has appropriate fiber-to-fiber bonding during the cutting process by real-time detection of the moisture content at the cutting position and targeted humidity adjustment at the cutting position according to the moisture content. This avoids problems such as burrs, cracks or unevenness on the cutting edge caused by too high or too low moisture content, thereby significantly improving the stability and consistency of cutting quality.

[0009] 2. This solution can reduce rework and scrap rate caused by poor cutting quality because it can ensure the stability and consistency of cutting quality. This not only improves production efficiency, but also reduces production costs. At the same time, high-quality cutting also improves the overall quality of the product, making the product more competitive in the market.

[0010] Furthermore, the humidity adjustment component includes a bellows; the bellows is arranged on one side of the operating table; a fan is arranged in the bellows; the output end of the fan is connected to an air supply pipe; a main channel and a plurality of secondary channels are arranged in the tool; the main channel is connected to the air supply pipe and the secondary channels respectively; the bottom of the secondary channels are connected to air outlets; the air outlets are linearly arranged on one side of the cutting edge of the tool; one side of the secondary channels is connected to a water storage chamber; a sponge column is arranged in the water storage chamber; an atomizer sheet is arranged on the top of the sponge column; the atomizer sheet is electrically connected to the control module respectively; electric heating wires are also arranged in the secondary channels; the electric heating wires are electrically connected to the control module respectively.

[0011] Beneficial effect: The fan in the bellows is controlled by the control module, and the wind enters the main channel-secondary channel-air outlet through the air supply pipe, and finally forms a wind curtain on the surface of the cutting position. When the humidity of a certain position of the cardboard needs to be increased, the control module controls the atomizing sheet in the air outlet corresponding to the position to work, and the atomizing sheet atomizes the water in the liquid storage cavity and brings it into the air outlet through the wind in the secondary channel, thereby humidifying the target position; when the humidity of a certain position of the cardboard needs to be reduced, the control module controls the operation of the electric heating wire in the air outlet corresponding to the position, so that the air outlet blows out hot air to evaporate the water in the position.

[0012] In this solution, through the careful layout of the bellows, air supply pipes, main channels, secondary channels and air outlets, the system can form an accurate air curtain at the cutting position to ensure the pertinence and effectiveness of humidity regulation. At the same time, by using the combination of atomizing sheets and heating wires, the system can flexibly humidify or dehumidify to meet the needs of different humidity conditions during the cardboard cutting process.

[0013] Furthermore, the detection module includes a microwave generator, a microwave receiver and a second moving component; a collecting tank is arranged in the operating table; a horizontal track is arranged on the side wall of the collecting tank; the second moving component includes a horizontal driving member, a horizontal lead screw and a horizontal nut seat; one end of the horizontal lead screw is rotationally matched with the horizontal track, and the other end of the horizontal lead screw is axially fixedly connected with the horizontal driving member; the horizontal driving member is used to drive the horizontal lead screw to rotate; the horizontal lead screw is threadedly matched with the horizontal nut seat; the horizontal nut seat is fixedly connected with the microwave generator; the microwave receiver is located on one side of the tool, and the microwave receiver is used to receive microwaves sent by the microwave generator along different cutting positions; the microwave receiver, the microwave generator and the horizontal driving member are all electrically connected to the control module.

[0014] Beneficial effect: The control module controls the operation of the horizontal driving member, so that the horizontal nut seat drives the microwave generator to move along the cutting position and emit microwaves. After passing through the cutting position, the microwaves are collected by the microwave receiver. By comparing the attenuation and phase changes of microwave signals at different positions, the distribution of moisture content in the cutting position can be inferred. Based on this information, the control module can determine which positions need humidification and which positions need dehumidification, and adjust the working state of the humidity adjustment component accordingly.

[0015] Furthermore, the control module is also used to control the operation of the microwave generator and the horizontal driving member when the cutting position needs to be dehumidified, so as to utilize microwaves to heat the moisture in the cutting position.

[0016] Beneficial effects: By precisely controlling the output power of the microwave generator and the moving speed of the horizontal drive, accurate heating and dehumidification of the water in the cutting position can be achieved. Microwave heating is efficient and fast, and can quickly increase the temperature of the water in the cutting position, accelerate its evaporation process, and significantly shorten the dehumidification time.

[0017] Furthermore, the clamping module includes a clamping plate and at least one locking assembly; the locking assembly includes a screw and a nut turntable; lifting grooves are provided on both sides of the top of the operating table; the two ends of the clamping plate are respectively slidably matched with the lifting grooves; the bottom of the screw is embedded in the lifting groove and fixedly connected to the top of the clamping plate; the screw is slidably matched with the operating table; the screw is threadedly matched with the nut turntable; the bottom of the nut turntable is rotationally matched with the operating table.

[0018] Beneficial effects: By rotating the nut turntable, the user can easily adjust the height of the screw, thereby driving the clamping plate to move up and down in the lifting slot. This design allows the clamping module to flexibly adapt to cardboards of different thicknesses, ensuring that the cardboard is firmly clamped. When the clamping plate contacts the cardboard, the self-locking function of the screw and the nut turntable can firmly fix the clamping plate in the specified position. This design not only ensures the stability of the cardboard, but also avoids the movement or deformation of the cardboard during processing.

[0019] Furthermore, a plurality of suction cups are arranged at the bottom of the clamping plate; a throat is arranged in the air supply pipe; the throat is connected with a shunt pipe; and the shunt pipe is connected with each suction cup respectively.

[0020] Beneficial effect: When the air supply pipe operates normally, the air flow through the throat will produce a significant increase in flow velocity, thus forming a negative pressure area in the diversion pipe. This negative pressure acts on the inside of the suction cup, allowing the suction cup to tightly adsorb the upper end surface of the cardboard. This adsorption effect not only enhances the stability of the cardboard during processing, but also effectively prevents the cardboard from moving or tilting due to external forces.

[0021] When the knife cuts the cardboard, a certain shear force will be generated, which may cause the edge of the cardboard to deform. The upward suction force generated by the suction cup can counteract this shear force, thereby significantly reducing the probability of deformation of the cardboard edge. This design not only improves cutting accuracy, but also ensures product quality.

[0022] Through the adsorption of the suction cup, the clamping effect of the clamping module on the cardboard is significantly enhanced. Even if the cardboard surface is uneven or stained, the suction cup can firmly adsorb it through the negative pressure. This design improves the adaptability and reliability of the clamping module.

[0023] Furthermore, support carriers are provided on both sides of the operating table; vertical rails are provided on the support carriers respectively; both ends of the tool are slidably matched with the vertical rails respectively; the first moving component is located in any vertical rail; the first moving component includes a vertical lead screw, a vertical drive member and a vertical nut seat; both ends of the vertical lead screw are rotationally matched with the vertical rails respectively; the vertical drive member is used to drive the vertical lead screw to rotate; the vertical lead screw is threadedly matched with the vertical nut seat; the vertical nut seat is fixedly connected to the tool; and the vertical drive member is electrically connected to the control module.

[0024] Beneficial effect: The vertical driving member is controlled by the control module to run, the vertical driving member drives the vertical lead screw to rotate, the vertical lead screw drives the vertical nut seat to run, and the vertical nut seat drives the tool to move up and down along the vertical slide rail, thereby realizing the cutting of the cardboard.

[0025] Furthermore, a flow limiting protrusion is provided at the connection point between the water storage chamber and the secondary channel.

[0026] Beneficial effect: The setting of the flow-limiting protrusion makes the air flow rate increase significantly when passing through the connection between the water storage chamber and the auxiliary channel due to the sudden decrease in the flow area, thereby generating local negative pressure in the area. This negative pressure effect helps to more effectively absorb the water vapor generated by the atomizer into the auxiliary channel, thereby improving the water vapor transmission efficiency.

[0027] Furthermore, a plurality of rotating grooves are arranged on the back side of the tool; the rotating grooves are respectively connected to the auxiliary channels; a grinding disc is rotatably connected in the rotating grooves; a plurality of blades are circumferentially arranged on one side of the grinding disc close to the auxiliary channel.

[0028] Beneficial effects: When air flows through the secondary channel, the air drives the blades to rotate using the principle of aerodynamics. The rotation of the blades further drives the grinding disc to rotate, realizing automatic trimming of the cut edges of the cut cardboard. This design does not require an additional power source, reducing energy consumption and costs. The rotation of the grinding disc can finely grind the cut edges of the cardboard, remove burrs and uneven parts, and make the edges of the cardboard smoother and neater. This helps to improve the overall quality and aesthetics of the product.

[0029] Furthermore, the cutting edge of the tool is arranged at an inclination.

[0030] Beneficial effect: The cutting edge of the cutter is set at an angle, so that when cutting the cardboard, the cutting edge can cut into the inside of the cardboard more quickly. This design reduces the resistance during the cutting process, thereby improving the cutting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The detection module is used to detect the moisture content of the cutting position. Specifically, the detection module mainly includes a microwave generator 103, a microwave receiver 801 and a second moving component; Figure 3As shown, a collecting tank 101 is provided in the operating table 1; a horizontal track 104 is provided on the side wall of the collecting tank 101, and specifically, the horizontal track 104 is parallel to the cutting position (the cutting position is a straight line area in this embodiment).

[0051] Preferably, as attached Figure 8 As shown, a plurality of suction cups 504 are bonded and fixed to the bottom of the clamping plate 5; Fig. 9 As shown, a throat 301 is provided in the air supply pipe 3, and the throat 301 and the air supply pipe 3 are integrated; the throat 301 is connected to the diverter pipe 4; the diverter pipe 4 is respectively connected to each suction cup 504. Specifically, a mainstream pipe and a plurality of branch pipes are provided in the splint 5, and the branch pipes correspond to the suction cups 504 one by one, and then the branch pipes converge in the mainstream channel, and are connected to the diverter pipe 4 through the mainstream channel, thereby realizing the connection between the diverter pipe 4 and each suction cup 504.

[0052] The control module is used to control the operation of the humidity regulating component based on the moisture content of the cutting position. Specifically, when the moisture content of the cutting position is lower than the preset interval, the control module controls the fan to operate, so that airflow is generated in each auxiliary channel 808, and controls the atomizing sheet 811 to operate, and then transports water vapor to the cutting position through the airflow to increase its moisture content; when the moisture content of the cutting position is higher than the preset interval, the control module controls the electric heating wire to operate, so as to increase the airflow temperature, thereby accelerating the evaporation of moisture in the cutting position.

[0053] The control module is also used to control the operation of the microwave generator 103 and the horizontal driving member 106 when the cutting position needs to be dehumidified, thereby increasing the power of the microwave generator 103 and using microwaves to heat the moisture in the cutting position.

[0054] The specific implementation process is as follows: initially, the cardboard 9 is placed on the operating table 1, the nut turntable 502 is turned clockwise to make the screw 501 drive the clamping plate 5 to move upward, and then the cardboard 9 is pushed under the clamping plate 5, and then the nut turntable 502 is turned counterclockwise to make the clamping plate 5 press against the upper end surface (i.e., the top) of the cardboard 9, thereby fixing the cardboard 9.

[0055] Then the staff starts the horizontal drive 106, so that the microwave generator 103 emits microwaves along the cutting position and scans a circle. After the microwaves pass through the cutting position, they are collected by the microwave receiver 801. Based on the collected microwave information, the control module determines the moisture content distribution of the paperboard 9 along the cutting position and determines the area that needs humidification or dehumidification. Then the control module controls the horizontal drive 106 to reset, and controls the vertical drive 804 and the fan to run at the same time. The vertical drive 804 drives the cutter 8 to cut downward. When the airflow generated by the fan passes through the throat 301, negative pressure is generated. The negative pressure acts on each suction cup 504 through the shunt pipe 4, so that the upper end surface of the paperboard 9 is firmly adsorbed. The adsorption force can offset the shear stress when the cutter 8 cuts downward, thereby reducing the edge deformation of the paperboard 9.

[0056] When the control module determines that the moisture content of the cutting position of the paperboard 9 is lower than the preset interval, the control module will control the atomizing sheet 811 corresponding to the cutting position (that is, determined by the air outlet 814 corresponding to the upper part of the cutting position, each air outlet 814 corresponds to an atomizing sheet 811, and the atomizing sheet 811 is located in the water storage chamber 809 of the secondary channel 808 connected to the air outlet 814) to operate, and then transport water vapor to the cutting position through the airflow to increase its moisture content; when the control module determines that the moisture content of the cutting position of the paperboard 9 is higher than the preset interval, the control module controls the electric heating wire to operate and / or controls the microwave generator 103 to increase the power, and accelerates the evaporation of moisture in the cutting position by using the heat carried by the airflow and / or microwave heating.

[0057] At the same time, when the airflow is delivered to the main channel 807-secondary channel 808 through the air supply pipe 3, the airflow will drive the blade 8061 to rotate, and then drive the sanding disc 806 to rotate. When the cutter 8 cuts the edge of the cardboard 9, the sanding disc 806 will trim and smooth the new cut edge, thereby improving the flatness of the edge of the cardboard 9.

[0058] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and / or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
