Description

Technical Field

[0001] This application relates to the field of paper box packaging technology, and in particular to a rapid creasing method for paper box creasing. Background Technology

[0002] When producing cardboard boxes or cartons for packaging, in order to ensure that the bending area of ​​the cardboard is neat and easy to bend during subsequent packaging, creases need to be pressed into the bending area of ​​the cardboard. Traditional crease molds are made of iron sheets, sponge, and rubber, inlaid on special wood (multi-layer board or bakelite board), which has a long production cycle and high cost.

[0003] For example, the invention patent with application number CN202010936975.0 discloses that by adding a thickener, amorphous silica, the viscosity of the indentation material (W substance) is increased. By extruding the W substance, it is adhered to the cardboard in the shape of the nozzle to obtain a better line cross-sectional shape and obtain continuous lines of the cross-section. After curing, it can replace the traditional indentation.

[0004] However, considering the current state of the die-cutting and creasing industry, the main method for producing non-metallic creasing lines relies on a screw to transmit power and output creasing material. Manufacturing creasing lines with varying patterns using existing technology requires nozzles of different shapes, making the process cumbersome. Furthermore, precision is difficult to control; please refer to the attached instruction manual. Figure 1 The starting and ending points of the crease lines are prone to stacking (shaped like match heads 01), and the ending points of the lines are prone to creating spikes 02 (due to the stickiness of the crease material and stringing), resulting in uneven creases on the cardboard box.

[0005] Therefore, improving the quality of the indentation lines is a technical problem that needs to be solved by those skilled in the art in light of the above-mentioned technical issues. Summary of the Invention

[0006] The purpose of this application is to provide a rapid line-making method for cardboard box creasing, which avoids the generation of match heads and punctures, greatly improves the uniformity of the creasing lines, and enhances the embossing quality.

[0007] To achieve the above objectives, this application provides a rapid creasing method for cardboard box creasing, comprising:

[0008] S1: The nozzle reaches the designated position according to the pre-designed instructions of the software, that is, the starting end of spraying the viscous indentation material;

[0009] S2: The nozzle moves down to the position where it contacts the placement surface, and at the same time, the viscous indentation material is extruded from the nozzle orifice;

[0010] S3: The nozzle immediately moves upward to a height L above the placement surface, and the nozzle moves along the graphic trajectory P on the placement surface;

[0011] S4: After the nozzle completes the movement command, the action stops, and the nozzle stops extruding the viscous indentation material;

[0012] S5: The nozzle moves down to the position where it contacts the placement surface, and moves outward a certain distance, and then the nozzle is raised according to the instruction;

[0013] S6: The UV curing point light source moves along the path of the sprayed adhesive indentation material, and uses the light source to cure the adhesive indentation material.

[0014] Preferably, in step S3, the nozzle moves once along the P direction, thus completing the movement command. At this point, L = 1.5d, where d is the nozzle orifice diameter.

[0015] Preferably, in step S3, after the nozzle moves once along the P direction, the nozzle immediately rises to a height H again, returns along the original path, and exceeds the length of the starting end M, thus completing the movement command. At this time, L = d, H = 1.5d, M = 1.5d, and d is the nozzle orifice diameter.

[0016] Preferably, the substrate to be coated with adhesive is placed on the placement surface, and the contact position in S2 and S5 refers to the distance h between the nozzle and the surface of the substrate to be coated with adhesive when the nozzle is working, where h is 0-0.5d and d is the nozzle orifice diameter.

[0017] Preferably, the P direction includes the X and Y directions, the nozzle is driven by a moving module and a head assembly, the moving module is located on one side of the placement surface and is movable relative to the placement surface in the Y direction; the head assembly is slidably disposed on the moving module, and the nozzle is disposed on the head assembly;

[0018] The moving module is used to drive the nozzle to move along the Y direction of the placement surface; the head assembly is used to drive the nozzle to move along the X direction of the placement surface.

[0019] Preferably, the head assembly includes a sliding plate slidably disposed with the moving module and a lifting plate slidably disposed on the sliding plate and moving towards or away from the placement surface, wherein the nozzle is disposed on the side of the lifting plate facing the placement surface;

[0020] The lifting plate is used to raise or lower the nozzle so that the nozzle reaches a specified height.

[0021] Preferably, the nozzle is connected to the rubber cylinder through a conveying channel, the other end of the rubber cylinder is connected to a compressed air source, and a cylinder is also provided on the lifting plate, with the valve core rod of the cylinder extending into the conveying channel;

[0022] The valve core rod is used to control the opening and closing of the conveying channel to control whether the viscous indentation material is extruded from the nozzle.

[0023] Preferably, a motor is fixedly mounted on the sliding plate, and a lead screw is connected to the power end of the motor. The lead screw cooperates with the slider, and the slider is fixedly connected to the lifting plate.

[0024] The motor drives the lifting plate to control the lifting and lowering of the nozzle.

[0025] Preferably, the UV curing point light source is rotatably mounted on the die head assembly so that the light beam emitted by the UV curing point light source can always correspond to the viscous indentation material extruded by the nozzle.

[0026] Preferably, the placement surface is a placement plane or a rotating roller;

[0027] When the placement surface is a plane, the two ends of the moving module are slidably set relative to the placement surface in the Y direction through the linear module;

[0028] When the placement surface is a rotating roller, the rotating roller rotates to make the moving module move in the Y direction relative to the placement surface.

[0029] Compared to the aforementioned background technology, the nozzle of this application reaches the starting end of the adhesive indentation material spraying according to software instructions. At this position, the nozzle moves down to the contact position with the placement surface, and the adhesive indentation material is uniformly extruded from the nozzle. At this time, the nozzle immediately moves up a certain distance. During the upward movement of the nozzle, the adhesive indentation material has already come into contact with the substrate, which is equivalent to stretching the adhesive indentation material upward from the upper surface of the substrate, thereby reducing the stacking of the adhesive indentation material at this point and avoiding match head formation. After the nozzle completes the movement instruction, it stops moving and stops extruding the adhesive indentation material. At this time, the nozzle moves down to the contact position with the placement surface and moves outward a certain distance. Then, according to the instruction, the nozzle rises. This action is equivalent to wiping the remaining adhesive indentation material on the nozzle onto the placement surface, and at the same time, it can cut off the stringiness formed at the end of the indentation line. Finally, the UV curing point light source moves along the spraying path of the adhesive indentation material to cure the sprayed adhesive indentation material and maintain its shape stability.

[0030] When drawing an indentation line, the adhesive nature of the indentation material prevents it from breaking immediately, forming a thin thread known as stringing. Stringing reduces the quality of the indentation line and creates spikes. This method overcomes the problems of stacking (shaped like match heads) at the beginning of the indentation line and spikes (caused by the adhesiveness of the indentation material and stringing) at the end of the line by using the stretching action of the nozzle and the wiping action after spraying, thus improving the quality of the indentation line.

It is used only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 2 As shown, in this embodiment, a rapid creasing method for cardboard box creasing is provided, the method comprising:

[0042] S1: The nozzle reaches the designated position according to the pre-designed instructions of the software, that is, the starting end of spraying the viscous indentation material;

[0043] S2: The nozzle moves down to the position where it contacts the placement surface, and at the same time, the viscous indentation material is extruded from the nozzle;

[0044] S3: The nozzle immediately moves upward to a height L above the placement surface. The nozzle then moves along the graphic trajectory P on the placement surface. Here, P includes both the X and Y directions. Please refer to [reference needed] for details. Figure 4 The nozzle moves along the X direction on the placement surface, or the nozzle moves along the Y direction on the placement surface;

[0045] S4: The nozzle stops moving after completing the movement command, and the nozzle stops extruding the viscous indentation material;

[0046] S5: The nozzle moves down to the position where it contacts the placement surface, and moves outward a certain distance, then the nozzle is raised according to the instruction;

[0047] S6: The UV curing point light source moves along the path of the sprayed adhesive indentation material, and uses the light source to cure the adhesive indentation material.

[0048] It should be noted that this method requires a wire-making device, which includes a moving module 2, a head assembly 4, and a UV curing point light source 15. The moving module 2 is located on one side of the placement surface 1 and is movable relative to the placement surface 1 in the Y direction. The placement surface 1 is used to place the substrate to be coated with adhesive.

[0049] The head assembly 4 is slidably mounted on the movable module 2 and is moved along the X direction of the placement surface 1; it should be noted that, please refer to Figure 4 The X and Y directions of the placement surface 1 are perpendicular to each other. By moving both the moving module 2 and the head assembly 4, the effect of spraying in any direction on the placement surface 1 can be achieved.

[0050] The head assembly 4 includes a sliding plate 5 slidably disposed with the moving module 2 and a lifting plate 9 slidably disposed on the sliding plate 5. The lifting plate 9 can move towards or away from the placement surface 1, thereby adjusting the distance between the nozzle 13 and the placement surface 1 or the substrate. The nozzle 13 is provided on the side of the lifting plate 9 facing the placement surface 1. The nozzle 13 is connected to the glue cylinder 14 through the conveying channel 12. The other end of the glue cylinder 14 is connected to a compressed air source, thereby using pneumatic transmission to extrude the viscous indentation material, overcoming the disadvantage of uneven extrusion of viscous indentation material caused by mechanical transmission.

[0051] In addition, a cylinder 10 is also provided on the lifting plate 9. The valve core rod 11 of the cylinder 10 extends into the conveying channel 12. The cylinder 10 is controlled by a solenoid valve to move, thereby controlling the opening and closing of the conveying channel 12 by the valve core rod 11.

[0052] The UV curing point light source 15 is set on the head assembly 4 and moves with the sliding plate 5. It can irradiate the sticky indented material after it is extruded from the nozzle 13, thereby curing it and maintaining the stability of its shape.

[0053] In summary, this line-making device utilizes the moving module 2 and the head assembly 4 to achieve X- and Y-axis spraying on the placement surface 1. Specifically, the moving module 2 can move relative to the placement surface 1 in the Y-axis, while the head assembly 4 can move relative to the placement surface 1 in the X-axis. When both the moving module 2 and the head assembly 4 move simultaneously, spraying can be achieved in any direction on the placement surface 1, thus providing various combinations of indentation lines. Furthermore, this application uses pneumatic extrusion instead of traditional mechanical transmission. Air has very low viscosity, resulting in low flow loss, high efficiency, more stable power output, uniform extrusion of viscous indentation material, and a cleaner medium, reducing pipe blockage and simplifying maintenance. A solenoid valve is also added. When energized, the valve core rod 11 moves upward, opening the conveying channel 12; when de-energized, the valve core rod 11 moves downward, closing the conveying channel 12. From the start to the end of printing the indentation line, the length error of the line can be precisely controlled within 0.5 mm. After the indentation line is sprayed, the indentation line is cured using a UV curing point light source 15 to maintain its shape permanently.

[0054] The aforementioned placement surface 1 can be a placement plane or a rotating roller, and the substrate to be coated is either laid on the placement plane or fitted onto the rotating roller, depending on the placement surface 1.

[0055] When the placement surface 1 is a flat surface, the two ends of the moving module 2 can be set to slide relative to the placement surface 1 in the Y direction through the straight module, and maintain the stability of the movement to ensure the quality of the sprayed indentation lines.

[0056] When the placement surface 1 is a rotating roller, the moving module 2 can naturally move relative to the placement surface 1 in the Y direction as the rotating roller rotates, which will not be described in detail here.

[0057] The sliding plate 5 can also be slidably mounted on the moving module 2 via the linear module. Please refer to [reference needed]. Figure 5 A linear module is provided at the contact point between the sliding plate 5 and the moving module 2, thereby maintaining the sliding plate 5 moving along the X direction of the placement surface 1.

[0058] like Figure 5 As shown, a motor 6 is fixedly mounted on the sliding plate 5. A lead screw 8 is connected to the power end of the motor 6, allowing the lead screw 8 to rotate with the power end of the motor 6. The lead screw 8 cooperates with a slider 7, which is fixed to the lifting plate 9. Thus, the lifting plate 9 is driven to move through the lead screw-slider connection structure. It should be noted that there are various ways to control the movement of the lifting plate 9, including but not limited to the method given in this embodiment, as well as linear modules, etc. These will not be detailed here, but all fall within the scope of protection of this application.

[0059] Based on the above embodiments, in order to improve the smoothness of the movement of the slider 7, the slider 7 can be slidably disposed along the wall of the sliding plate 5, and a limiting member is provided on the sliding plate 5 to limit the slider 7 to move only toward or away from the placement surface 1.

[0060] The cartridge 14 is filled with a viscous indentation material. The material is propelled along the conveying channel 12 by compressed air pressure, and extruded through the nozzle 13 to form indentation lines. The compressed air pressure is 0.5±0.02 MPa, the viscous indentation material is maintained within the range of 25±0.5℃, and the viscosity is 45000-46000 MPa·s. It should be noted that the above parameters are specific implementation parameters and can be adjusted according to actual conditions; no further restrictions are imposed here. A cable chain 3 is also provided between the head assembly 4 and the moving module 2 to hold the cables of the motor 6 and cylinder 10.

[0061] In addition, the UV curing point light source 15 is rotatably mounted on the head assembly 4, and the irradiation angle of the UV curing point light source 15 can be adjusted appropriately, so that the light beam emitted by the UV curing point light source 15 can always correspond to the viscous indentation material extruded by the nozzle 13, thereby improving the curing effect.

[0062] Based on the above embodiments, this method can achieve embossing lines with a stable cross-sectional shape using only one application of adhesive. Please refer to [link / reference]. Figure 2 When the head assembly 4 begins to execute the software's "instructions," the nozzle 13 first moves down to the position where it just contacts the placement surface 1, that is... Figure 2 At point O in the middle; at the same time, the solenoid valve opens, the cylinder 10 moves the valve core rod 11 to rise, the conveying channel 12 opens, and the viscous indentation material is subjected to air pressure (this air pressure is a preset value) and flows out of the nozzle 13 at a uniform speed.

[0063] Nozzle 13 then moves upward to a height L from the placement surface 1, where L = 1.5d, and d is the orifice diameter of nozzle 13. Figure 2 In the middle OA section; then, under the action of the sliding plate 5 or the moving module 2, the nozzle 13 moves at a constant speed along the X or Y direction, and the distance that the head assembly 4 moves is the length of the indentation line, i.e. Figure 2 Section AB. When one indentation line is written, the solenoid valve closes, the cylinder 10 returns to its original position, and the sliding plate 5, according to the pre-written program, moves the nozzle 13 down again to the position where it just contacts the placement surface 1. Figure 2 The middle BC segment. And move it to a point approximately 2mm to the side on the platform, that is... Figure 2 In the middle CD section, the residual sticky indentation material on the nozzle 13 is wiped off onto the placement surface 1, simultaneously cutting off the stringy ends of the indentation lines. Then the machine head moves upwards, i.e. Figure 2 The DE segment is used to complete the writing of the line. Finally, the head assembly 4 drives the UV curing point light source 15 to cure the entire indentation line, so that the written indentation line is pre-cured and its shape is stable.

[0064] This method can also be modified according to the actual situation, i.e., two-stage stacking of glue application can be used. After the sliding plate 5 slides only once along the X direction on the moving module 2, or after the moving module 2 moves only once along the Y direction, the nozzle 13 immediately rises again to a height H, returns along the original path, and exceeds the starting end M length, thus completing the movement command. Please refer to... Figure 3 When the head assembly 4 starts executing the software's "instructions", the nozzle 13 first moves down to position A1, the distance between A1 and the placement surface 1 is L = d, where d is the nozzle 13 orifice diameter; at the same time, the solenoid valve opens, the cylinder 10 actuates the valve core rod 11 to rise, the conveying channel 12 opens, and the viscous indentation material is subjected to air pressure (this air pressure is a preset value) and flows out of the nozzle 13 at a uniform speed.

[0065] Under the action of the sliding plate 5 or the moving module 2, the nozzle 13 moves at a constant speed along the X or Y direction. When it reaches position B1, the nozzle 13 immediately rises by a height H, where H = 1.5d, and returns to position A2 at the same speed. The position A2 is longer than position A1 by a length M, where M = 1.5d. This completes the double-layer stacking adhesive application. After the movement command is completed, the nozzle 13 is moved down again to the position where it just touches the placement surface 1. Figure 3 Section A2C1. And move it to a point approximately 2mm to the side on the platform, i.e. Figure 3 In section C1D1, the nose of the aircraft then moves upward, that is... Figure 3 In segment D1E1, the line is written, and finally the head assembly 4 drives the UV curing point light source 15 to cure the entire indentation line.

[0066] It should be noted that within the first 10 seconds of printing the indentation lines (for longer lines, we stop printing around 8 seconds for pre-curing before continuing to print the remaining lines, with a preferred printing speed of 0.15m / s), we use a specific wavelength UV curing point light source (15W) for real-time pre-curing, which effectively maintains the cross-sectional shape of the lines. The point light source power is selected as 5W, the distance between the point light source and the indentation lines is controlled at 35-40mm, and the point light source moving speed is 50mm / s. Finally, a surface light source is used to cure the entire indentation mold, ensuring the permanent stability of the line shape.

[0067] In S2 and S5, as well as the contact position mentioned above, the distance h between the nozzle 13 and the surface of the substrate to be coated is 0-0.5d, where d is the orifice diameter of the nozzle 13.

[0068] When spraying viscous indentation material in the Y direction, for the placement plane, the transverse module only needs to move a certain distance in coordination with the placement plane, and the viscous indentation material is uniformly extruded from the nozzle 13 along the Y direction; for the roller, the roller only needs to rotate at a certain angle, and the nozzle 13 is uniformly extruded relative to the placement surface 1 in the Y direction when the roller rotates.

[0069] If writing continues in the X direction, the moving module 2 will stop moving according to the program instructions. At this time, the head assembly 4 will move along the guide rail on the moving module 2, that is, along the X direction.

[0070] To improve the adhesion between the indentation lines and the substrate and extend their service life, this design uses a UV-curing agent with relatively low viscosity. The viscous indentation material is extruded through nozzle 13. Because viscous indentation materials exhibit higher surface activity and migration speed with lower viscosity, the extruded material adheres to the substrate in a nearly circular columnar strip, which flows and gradually flattens over time. In this application, curing occurs before the indentation lines flatten. To achieve the ideal cross-sectional shape of the indentation lines without reducing adhesion, a UV curing point light source 15 is added. Pre-curing is performed immediately after each indentation line is applied to maintain its cross-section. This eliminates the need for amorphous silica thickeners to maintain the shape of the indentation lines, overcoming the problems of reduced adhesion and short extrusion life.

[0071] In summary, this method utilizes the aforementioned line-making device. Specifically, the head assembly 4 reaches the starting point of the adhesive indentation material spraying according to software instructions. The lifting plate 9, according to instructions, moves the nozzle 13 downwards to the contact position with the placement surface 1. Simultaneously, the cylinder 10 actuates, causing the valve core rod 11 to rise, opening the conveying channel 12, and the adhesive indentation material is uniformly extruded from the nozzle 13. At this time, the lifting plate 9 immediately moves upwards a certain distance. During the upward movement of the nozzle, the adhesive indentation material has already contacted the substrate, effectively stretching the adhesive indentation material upwards from the substrate surface, thereby reducing the accumulation of adhesive indentation material and preventing matchstick-like residue. The sliding plate 5 slides along the X-direction on the moving module 2, or the moving module 2 moves along the Y-direction of the placement surface 1, thus completing the X-direction or Y-direction spraying. After the spraying is completed, the valve core lever 11 moves down to shut off the conveying channel 12, and the lifting plate 9 again moves the nozzle 13 down to the contact position of the placement surface 1. The sliding plate 5 or the moving module 2 moves the lifting plate 9 to a certain distance to the outside, and then the lifting plate 9 is raised. This action is equivalent to wiping the residual sticky indentation material on the nozzle 13 onto the placement surface 1, and at the same time, it can cut off the stringiness formed at the end of the indentation line. Finally, the UV curing point light source 15 moves along the spraying path of the sticky indentation material, so that the photosensitive material on the surface of the indentation line is pre-cured, thereby making the indentation line maintain a stable shape.

[0072] When drawing an indentation line, the adhesive material doesn't immediately break due to its stickiness, forming a thin thread known as stringing. Stringing reduces the quality of the indentation line and creates spikes. This method overcomes the problems of stacking (shaped like match heads) at the beginning of the indentation line and spikes (caused by the stickiness of the material and stringing) at the end of the line by using precise control of pneumatic transmission and wiping action after spraying, thus improving the quality of the indentation line.

[0073] In summary, this application utilizes pneumatic transmission to overcome the uneven extrusion of viscous indentation material caused by mechanical transmission. The addition of a UV curing point light source 15 and the use of a high-power UV lamp for curing eliminates the need for amorphous silica thickeners to improve the viscosity of the viscous indentation material, thus enhancing the shape retention of the indentation lines and overcoming the problems of reduced adhesion between the lines and the substrate and short extrusion life. Furthermore, the optimized spraying process path overcomes the problems of easy stacking at the starting points of the indentation lines and the formation of spikes at the ending points, thereby improving the quality of the indentation lines. After continuous multi-stage spraying of combined indentation lines, it can be used for the production of indentation lines on coated paper, corrugated paper, and other types of boxes.
