Description
Technical Field
[0001] The present invention relates to a device for alternately cutting corrugated base paper longitudinally and transversely. Background Art
[0002] Corrugated base paper, also known as corrugated medium, is the raw material paper used to form the corrugated core of corrugated board. The cutting of corrugated base paper is mainly divided into methods such as mechanical tool cutting and laser cutting. When using mechanical tool cutting, for cross-cutting, a flying knife cuts like scissors, and for longitudinal cutting, a very thin circular knife cuts the corrugated paper by means of the high-speed rotation of the knife. The structure of corrugated base paper is relatively special, being a wavy core layer. When using mechanical tools for alternately cutting longitudinally and transversely, the cutting direction needs to be adjusted multiple times. During the cutting process, the cutting head needs to directly contact the surface of the corrugated paper. The moving cutting head will exert pressure on the corrugated paper and is prone to deviation and deformation of the corrugated paper due to vibration or friction, affecting the dimensional accuracy. The transverse and longitudinal cutting tools need to coordinate their movements. If the synchronism between the upper and lower knives is poor, it will result in rough edges or incomplete cutting. The fine dust generated during cutting is easily attached to the edge of the cutting line and needs to be cleaned in real time to avoid secondary pollution. Therefore, laser cutting may have greater advantages in some fields. Laser cutting uses a focusing lens to focus the laser beam on the material surface to melt the material, and at the same time, a compressed gas coaxial with the laser beam blows away the melted material, and the laser beam and the material move relative to each other along a certain trajectory to form a cut of a certain shape. However, due to the relatively special structure of corrugated base paper, which has a wavy outer surface, it is impossible to accurately focus on the outer surface of the corrugated base paper during laser cutting, affecting the temperature of the outer surface of the corrugated base paper, which may cause local burning or carbonization. For multiple layers of stacked corrugated base paper, there may also be problems such as incomplete burning or over-burning due to focus drift, affecting the cutting quality.
[0003] Therefore, if the focusing problem of laser cutting can be solved, it will be of great significance for the laser cutting of corrugated base paper. Summary of the Invention
[0004] The purpose of the present invention is to provide a device for alternately cutting corrugated base paper longitudinally and transversely to solve the technical problem that the cutting quality is affected by the focusing problem during the laser cutting of corrugated base paper.
[0005] The technical solution of the present invention is as follows: A device for alternately cutting corrugated base paper longitudinally and transversely includes: A processing platform; A laser generator; A laser head for emitting a laser beam, which is flexibly connected to the laser generator; A corrugated hard tray, having the same shape as the corrugated base paper to be processed, for lining under the corrugated base paper to be processed and fixed on the processing platform; A guide pin mechanism, including a first linear motion mechanism, a guiding spring mechanism, a guide pin frame, and a second linear motion mechanism; The first linear motion mechanism includes a guide rail and a slider. The guide rail is fixed relative to the processing platform, and the length of the guide rail is arranged along the transverse direction of the corrugated base paper. The slider slides along the guide rail. The guiding spring mechanism includes an inner sleeve and an outer sleeve that are slidably sleeved with each other for guiding, and a spring sleeved outside the outer sleeve. Spring seats are respectively provided at the outer ends of the inner and outer sleeves. The two ends of the spring respectively abut and cooperate with the two spring seats to provide an elastic force in the direction of moving the inner and outer sleeves away from each other. One of the two spring seats is fixed relative to the slider, and the other is fixed with the guide pin holder. The guide pin holder includes guide pins extending towards the bottom surface of the corrugated hard tray and a support frame extending upwards to an area above the corrugated hard tray. Under the action of the spring, the guide pins are always in contact with the lower surface of the corrugated hard tray. The second linear motion mechanism includes a fixed block and an electric control telescopic rod. The fixed block is fixed on the upper part of the support frame. The electric control telescopic rod extends towards the area above the corrugated hard tray, and the outer end of the electric control telescopic rod is fixed with the laser head. The corrugated base paper is placed on the corrugated hard tray. After the laser head is focused, when cutting transversely, the slider is driven to slide along the guide rail, and the upper ends of the guide pins slide in contact with the lower surface of the corrugated hard tray. The laser head is driven to synchronously lift and lower through the support frame and the second linear motion mechanism, ensuring that the focus of the laser head always falls on the upper surface of the corrugated base paper to be processed. When cutting longitudinally, the second linear motion mechanism drives the laser head to move longitudinally for cutting.
[0006] On the basis of the above technical solution, the further improvement is as follows: Ball bearings are rotatably assembled on the upper part of the guide pins, and the guide pins rely on the ball bearings to roll and cooperate with the bottom of the corrugated hard tray.
[0007] On the basis of the above technical solution, the further improvement is as follows: Horizontally and vertically cut slits are preset on the corrugated hard tray for the laser beam to pass through.
[0008] On the basis of the above technical solution, the further improvement is as follows: The first linear motion mechanism is a linear motor, and the second linear motion mechanism is an electric linear push rod.
[0009] On the basis of the above technical solution, the further improvement is as follows: The corrugated hard tray is a multi-piece splicing structure, and the splicing joints correspond to the horizontally and vertically cut slits.
[0010] On the basis of the above technical solution, the further improvement is as follows: The corrugated hard tray is movable to adaptively adjust the position of the horizontally and vertically cut slits.
[0011] On the basis of the above technical solution, the further improvement is as follows: The material of the corrugated hard tray is high-hardness martensitic stainless steel.
[0012] On the basis of the above technical solution, the further improvement is as follows: The axis of the laser head is perpendicular to the processing platform.
[0013] On the basis of the above technical solution, the further improvement is as follows: The material of the guide pin holder is high-hardness martensitic stainless steel.
[0014] Advantages of the present invention: In the prior art, due to the relatively special structure of corrugated base paper, which has a wavy outer surface, it is impossible to accurately focus on the outer surface of the corrugated base paper during laser cutting, affecting the temperature of the outer surface of the corrugated base paper and causing local charring or carbonization. For multiple layers of stacked corrugated base paper, there may also be problems such as incomplete burning or overburning due to focus drift, affecting the cutting quality. To solve this problem and enable laser cutting technology to be better applied to the cutting of corrugated base paper and even materials with uneven outer surfaces similar to corrugated base paper, and to avoid using technologies such as sensors and electronic control, because electronic control technology requires data acquisition, calculation, and setting of complex and precise actuators, which will cause a significant increase in the cost of the laser cutting machine. The main idea of the present invention is to use a simple mechanical mechanism to real-time sense the unevenness of the surface of the material to be processed and transmit it to the laser head through a direct mechanical transmission method, so as to avoid using complex algorithms to control the focal length change of the laser beam. Instead, after one-time focusing, due to the linkage between the laser head and the material surface through the mechanical structure, the focus of the laser beam is always located at the set position, solving such problems in a low-cost manner or providing a direction for solving such problems.
[0015] Specifically, the working principle of the corrugated base paper crosswise and lengthwise alternating cutting device of the present application is as follows: First, the connection between the laser head and the laser generator is changed to a flexible connection, that is, the displacement of the laser head is no longer controlled by the original equipment, which also eliminates the mechanical actuator for driving the laser head to move in the original laser cutting equipment. Second, since the corrugated base paper is relatively soft, it is impossible to directly contact the surface of the corrugated base paper with a guide pin to drive the laser head to move synchronously. Therefore, a corrugated hard tray with the same shape as the corrugated base paper is specially designed. By utilizing the high hardness of the corrugated hard tray, the contact between the guide pin and its lower surface will not cause the corrugated hard tray to deform, while direct contact between the guide pin and the corrugated base paper will cause the corrugated base paper to deform. The corrugated hard tray is perfectly fitted with the corrugated base paper to replace the lower surface of the corrugated base paper. The movement of the guide pin along the lower surface of the corrugated hard tray is equivalent to moving along the lower surface of the corrugated base paper. Furthermore, the setting of the guide pin mechanism is the biggest core improvement of the present application. It not only needs to be perfectly fitted with the lower surface of the corrugated hard tray to synchronously transmit the concave and convex changes of the material to be processed to the laser head, but also needs to be driven to move horizontally. The use of a guiding spring mechanism perfectly and ingeniously solves this contradiction because the guiding spring mechanism can ensure that the guide pin always abuts against the lower surface of the corrugated hard tray, and at the same time, it can rigidly transmit the position of the first linear motion mechanism to the guide pin holder in the radial direction, and then synchronously transmit it to the laser head. Due to the mutual sleeving structure of the inner and outer sleeves and the spring of the guiding spring mechanism, it has the characteristics of axially transmitting elastic force and radially transmitting rigid displacement. At the same time, since the support frame and the guide pin are fixed on the upper part of the guiding spring mechanism, the concave and convex displacement of the material detected by the guide pin can be directly transmitted to the laser head in a pure rigid manner. The setting of the second linear motion mechanism can not only meet the requirement of synchronously and losslessly transmitting the vertical displacement of the guide pin to the laser head, but also drive the laser head to move longitudinally. This function can not only adjust the longitudinal position of the laser head when the laser is not turned on, so that it is aligned with a suitable position during horizontal cutting, such as aligning with the cutting seam position, but also directly perform longitudinal cutting when the laser is turned on. In short, the technical solution of the present application can maintain a constant distance between the laser head and the cutting point of the corrugated base paper by means of direct mechanical transmission, that is, to ensure that the focus is always in a suitable position, and there is no need for complex electronic control components, so the cost is very low and it is easy to promote and use.
[0016] Further, setting balls on the upper part of the guide pin can change the friction between the guide pin and the corrugated hard tray from sliding friction to rolling friction, significantly reducing the magnitude of the friction force, making its relative movement smoother, and also avoiding processing errors caused by the bending deformation of the guide pin due to the unsmooth movement of the guide pin.
[0017] Further, the improvements of selecting linear motors, electric linear push rods, and using high-hardness materials for the corrugated hard tray and the guide pin holder are all to reduce the deformation error of mechanical transmission components, improve the accuracy of mechanical transmission, and thus improve the accuracy of laser cutting.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.
[0022] The features and performance of the present invention will be further described in detail below in conjunction with embodiments.
[0023] A specific embodiment of a corrugated base paper crosswise and lengthwise alternating cutting device of the present invention: As Figures 1-4 shown, the corrugated base paper crosswise and lengthwise alternating cutting device of this embodiment is an improvement based on an existing laser cutting machine. Its processing platform, laser generator, laser head 2 and other components are all of the prior art and will not be elaborated here. However, the laser head 2 is no longer driven by the original driving mechanism, but is fixed on the special guide pin frame 43 of this application. Its rear end is connected to the laser generator and other components in the middle: that is, the laser head 2 is only used to emit laser beams and is flexibly connected to the laser generator. The axis of the laser head 2 is perpendicular to the processing platform.
[0024] The corrugated hard tray 3 has the same shape as the corrugated base paper 1 to be processed, is used to line the corrugated base paper 1 to be processed, and is fixed on the processing platform, for example, fixed by a tooling fixture. The corrugated hard tray 3 is preset with hollowed-out crosswise and lengthwise cutting slits 31 for the laser beam to pass through. The material of the corrugated hard tray 3 is high-hardness martensitic stainless steel. In other embodiments, the corrugated hard tray 3 is a multi-piece splicing structure, and the splicing joints correspond to the crosswise and lengthwise cutting slits 31. The corrugated hard tray 3 can be moved to adaptively adjust the position of the crosswise and lengthwise cutting slits 31. In other embodiments, there may be various types of corrugated hard trays, because the equipment of this application is likely to be used for cutting various types of corrugated base papers. The surface shapes, the distances between the wave peaks and wave valleys, and the sizes of different corrugated base papers may be different. At this time, it is necessary to prepare various corrugated hard trays adaptively. The shape of each corrugated hard tray is the same as the shape of the corresponding corrugated base paper. Such a design enables the cutting device of this application to automatically match by relying on the guide pin mechanism when facing corrugated base papers with different surface shapes, without the need for positioning and tool setting, the operation is simpler, and the professional requirements for operators are lower.
[0025] As Figure 1As shown, the guide pin mechanism 4 includes a first linear motion mechanism, a guide spring mechanism 42, a guide pin holder 43, and a second linear motion mechanism. In this embodiment, the first linear motion mechanism is a linear motor 41, and the second linear motion mechanism is an electric linear push rod 44.
[0026] Specifically, the first linear motion mechanism includes a guide rail 412 and a slider 411. The guide rail 412 is fixed relative to the processing platform, and the length of the guide rail 412 is arranged along the transverse direction of the corrugated base paper 1. The slider 411 slides along the guide rail 412.
[0027] As Figure 2 shown, the guide spring mechanism 42 includes an inner sleeve 421, an outer sleeve 422 that are slidably sleeved with each other in a guiding manner, and a spring 423 sleeved outside the outer sleeve. Spring seats 424 are respectively provided at the outer ends of the inner and outer sleeves. The two ends of the spring 423 are respectively in abutting cooperation with the two spring seats 424 to provide an elastic force in the direction of moving the inner and outer sleeves away from each other. One of the two spring seats 424 is fixed relative to the slider 411, and the guide pin holder 43 is fixed on the other.
[0028] The guide pin holder 43 includes a guide pin 431 extending towards the bottom surface of the corrugated hard tray 3 and a support frame 432 extending upwards to an area above the corrugated hard tray 3. Under the action of the spring 423, the guide pin 431 always fits against the lower surface of the corrugated hard tray 3; a ball 4311 is rotatably assembled on the upper part of the guide pin 431, and the guide pin 431 relies on the ball 4311 to rollingly cooperate with the bottom of the corrugated hard tray 3. The material of the guide pin holder 43 is high-hardness martensitic stainless steel.
[0029] The second linear motion mechanism includes a fixed block 441 and an electric control telescopic rod 442. The fixed block 441 is fixed on the upper part of the support frame 432. The electric control telescopic rod 442 extends towards the area above the corrugated hard tray 3, and the outer end of the electric control telescopic rod 442 fixes the laser head 2.
[0030] Setting the ball 4311 on the upper part of the guide pin 431 can change the friction between the guide pin 431 and the corrugated hard tray 3 from sliding friction to rolling friction, significantly reducing the magnitude of the friction force, making its relative movement smoother, and also avoiding the processing error caused by the bending deformation of the guide pin 431 due to the unsmooth movement of the guide pin 431. The improvements of selecting the linear motor 41, the electric linear push rod 44, and using high-hardness materials for the corrugated hard tray 3 and the guide pin holder 43 are all to reduce the deformation error of the mechanical transmission components, improve the precision of the mechanical transmission, and thus improve the precision of laser cutting.
[0031] During operation, the corrugated base paper 1 is placed on the corrugated hard tray 3. After the laser head 2 is focused, during cross-cutting, the driving slider 411 slides along the guide rail 412, and the upper end of the guide pin 431 slides along the lower surface of the corrugated hard tray 3. The laser head 2 is driven to move up and down synchronously via the support frame 432 and the second linear motion mechanism, ensuring that the focus of the laser head 2 always falls on the upper surface of the corrugated base paper 1 to be processed. During longitudinal cutting, the second linear motion mechanism drives the laser head 2 to move longitudinally for cutting.
[0032] In the prior art, due to the relatively special structure of the corrugated base paper 1, which has a wavy outer surface, it is impossible to accurately focus on the outer surface of the corrugated base paper 1 during laser cutting, which affects the temperature of the outer surface of the corrugated base paper 1 and may cause local burning or carbonization. For the multi-layer stacked corrugated base paper 1, there may also be problems such as incomplete burning or over-burning due to focus drift, affecting the cutting quality. To solve this problem and enable the laser cutting technology to be better applied to the cutting of the corrugated base paper 1 and even materials with uneven outer surfaces similar to the corrugated base paper 1, and to avoid using technologies such as sensors and electronic control, because the electronic control technology requires data collection, calculation, and setting of complex and precise actuators, which will cause a significant increase in the cost of the laser cutting machine. The main idea of the present invention is to use a simple mechanical mechanism to sense the unevenness of the surface of the material to be processed in real time and transmit it to the laser head 2 through a direct mechanical transmission method, so as to avoid using complex algorithms to control the focal length change of the laser beam. Instead, after one-time focusing, due to the linkage between the laser head 2 and the material surface through the mechanical structure, the focus of the laser beam is always located at the set position, solving such problems in a low-cost manner or providing a direction for solving such problems.
[0033] Specifically, the working principle of the corrugated base paper crosswise and lengthwise alternating cutting device of the present application is as follows: First, the connection between the laser head 2 and the laser generator is changed to a flexible connection, that is, the displacement of the laser head 2 is no longer controlled by the original equipment, which also eliminates the mechanical actuator for driving the movement of the laser head 2 in the original laser cutting equipment. Secondly, since the corrugated base paper 1 is relatively soft, it is impossible to directly contact the surface of the corrugated base paper 1 with the guide pin 431 to drive the synchronous movement of the laser head 2. Therefore, a corrugated hard tray 3 with the same shape as the corrugated base paper 1 is specially designed. Due to the high hardness of the corrugated hard tray 3, the contact between the guide pin 431 and its lower surface will not cause deformation of the corrugated hard tray 3, while if the guide pin 431 directly contacts the corrugated base paper 1, it will cause deformation of the corrugated base paper 1. The corrugated hard tray 3 is perfectly fitted with the corrugated base paper 1 to replace the lower surface of the corrugated base paper 1. The movement of the guide pin 431 along the lower surface of the corrugated hard tray 3 is equivalent to the movement along the lower surface of the corrugated base paper 1. Furthermore, the setting of the guide pin mechanism 4 is the biggest core improvement of the present application. It not only needs to be perfectly fitted with the lower surface of the corrugated hard tray 3 to synchronously transmit the concavo-convex changes of the material to be processed to the laser head 2, but also needs to be driven to move horizontally. The use of the guiding spring mechanism 42 perfectly and ingeniously solves this contradiction, because the guiding spring mechanism 42 can ensure that the guide pin 431 always abuts against the lower surface of the corrugated hard tray 3, and at the same time, it can rigidly transmit the position of the first linear motion mechanism to the guide pin holder 43 in the radial direction, and then synchronously transmit it to the laser head 2. Due to the mutual sleeving structure of the inner and outer sleeves and the spring 423 of the guiding spring mechanism 42, it has the function of axially transmitting elastic force and radially transmitting rigid displacement. At the same time, since the support frame 432 and the guide pin 431 are fixed on the upper part of the guiding spring mechanism 42, the concavo-convex displacement of the material detected by the guide pin 431 can be directly transmitted to the laser head 2 in a pure rigid manner. The setting of the second linear motion mechanism can not only meet the requirement of synchronously and losslessly transmitting the vertical displacement of the guide pin 431 to the laser head 2, but also drive the laser head 2 to move longitudinally. This function can not only adjust the longitudinal position of the laser head 2 when the laser is not turned on, so that it is aligned with a suitable position during transverse cutting, such as aligning with the cutting seam 31 position, but also directly perform longitudinal cutting when the laser is turned on. In short, the technical solution of the present application can maintain a constant distance between the laser head 2 and the cutting point of the corrugated base paper 1 by means of direct mechanical transmission, that is, to ensure that the focus is always at a suitable position, and no complex electronic control components are required, so the cost is very low and it is easy to promote and use.

The scope of patent protection of the present invention is subject to the claims. All equivalent structural changes made by using the description and drawings of the present invention shall be included in the protection scope of the present invention by the same token.
