[0002] In the field of packaging and printing technology, the production of the embossing die base mold is a necessary step in the production of foldable packaging. Its production efficiency is related to the production efficiency of packaging products, while its production precision is related to the quality and precision of packaging products.

[0003] In traditional embossing techniques, the embossing strip needs to be cut and trimmed, the special positioning strip of the embossing strip needs to be fitted and glued to the ribs of the die template, the die template with the embossing strip is then attached to the base plate, and finally the die template is removed and the useless positioning strip is removed. The above cutting and pasting processes are carried out separately, which is time-consuming and labor-intensive. Moreover, the pasting accuracy depends on the worker's skill level and operational proficiency. In addition, the embossing strip needs to be accompanied by a special positioning strip, which is costly.

[0004] In conclusion, how to develop a convenient and low-cost automatic embossing die making device is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an automatic embossing mold plate making device, which realizes the automatic feeding, cutting and pasting of embossing strips.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic embossing mold making device includes a mold making platform for mounting a base plate, a machine head for conveying and cutting embossing strips, a machine head motion assembly, and a control device. The machine head motion assembly is used to drive the machine head to perform horizontal movement and orientation adjustment. The mold making platform, the machine head, and the machine head motion assembly are all signal connected to the control device.

[0008] The machine head includes a machine head mounting plate, which is provided with a feeding module for conveying the creasing strip, a pressure roller assembly for bonding the creasing strip to the base plate, and a cutting module for cutting the creasing strip.

[0009] Preferably, the feeding module includes a material tray for winding the crease strip, a guide wheel, and a bottom paper receiving assembly for separating the bottom paper of the crease strip. The material tray and the guide wheel are rotatably mounted on the machine head mounting plate. The bottom paper receiving assembly is located between the material tray and the pressure wheel assembly along the conveying direction of the crease strip, so that the crease strip after separating the bottom paper is pressed and adhered to the surface of the base plate by the pressure wheel assembly.

[0010] Preferably, the feeding module further includes a guide rail for guiding and limiting the indentation strip after the base paper is separated, and the inner surface of the guide rail is provided with an anti-stick coating to prevent the indentation strip from sticking together.

[0013] When cutting the end of the crease strip, the pallet power assembly controls the cutting pallet to move towards the cutting baffle so that the cutting pallet abuts against the cutting baffle. The cutting power assembly drives the cutting blade to move towards the crease strip so that the crease strip is pressed against the cutting pallet and cut.

[0014] Preferably, the cutting tray is equipped with a brake block. When the cutting tray moves to the cutting position, the brake block abuts against the adhesive backing of the crease strip to press the crease strip firmly into the guide rail and prevent the crease strip from moving during cutting.

[0015] Preferably, the outer edge of the molding platform is provided with a waste bin for collecting waste materials, and the machine head mounting plate is provided with an air nozzle for blowing waste materials toward the waste bin, the air nozzle being positioned directly opposite the cutting module.

[0016] Preferably, the pressure roller assembly includes a pressure roller and a pressure roller cylinder. The pressure roller cylinder is mounted on the machine head mounting plate via a pressure roller bracket. The pressure roller is located at the bottom of the cylinder rod of the pressure roller cylinder, so that the pressure of the pressure roller on the indentation strip can be adjusted by adjusting the cylinder pressure of the pressure roller cylinder.

[0017] Preferably, the head motion assembly includes an X-axis motion assembly, a Y-axis motion assembly, and a head rotation assembly. The fixed end of the X-axis motion assembly is connected to the molding platform, and the X-axis motion assembly is used to drive the head to move along the X-axis direction.

When the rotary motor rotates, the output shaft of the rotary motor drives the main rotation shaft and the machine head mounting plate to rotate synchronously.

[0021] During operation, for a certain crease line ab on the base plate where a crease strip needs to be pasted, the control device controls the head-end cutting component to cut the crease strip, and then controls the machine head movement component to move and rotate the machine head so that the orientation of the machine head is the same as the orientation of the crease line ab, and the end point of the cut crease strip is aligned with one end point a of the crease line ab. Then, the machine head movement component is controlled to move the machine head along the crease line ab, and the crease strip is pasted onto the base plate along the extension direction of the crease line ab.

[0022] When the crease strip moves to point b, the other end of the crease line ab, the control device controls the tail cutting component to cut the crease strip, thereby completing the pasting of the crease strip along the crease line ab.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The core of this invention is to provide an automatic embossing mold plate-making device, which realizes the automatic feeding, cutting and pasting of embossing strips. Compared with manual cutting and pasting, the pasting and cutting efficiency is high, and the pasting direction and size control of the embossing strips are more accurate, effectively improving the plate-making efficiency and accuracy.

[0033] It should be noted that, please refer to... Figure 3 All the crease lines 03 of the crease template are straight segments, without any broken segments, in order to avoid the crease strips 01 pressing against each other at the bends when they are attached to the base plate 02 along the crease lines 03. This would prevent the upper surface of the crease strips 01 from being no longer parallel to the base plate 02, or the width of the crease strips 01 from suddenly increasing at the bends, thus affecting the crease quality of the crease template.

[0034] The automatic embossing mold making device provided by the present invention includes a mold making platform 1 for mounting a base plate 02, a machine head 5 for conveying and cutting embossing strips 01, a machine head motion component, and a control device. The machine head motion component is used to drive the machine head 5 to perform horizontal movement and orientation adjustment. The mold making platform 1, the machine head 5, and the machine head motion component are all signal connected to the control device.

[0035] The machine head 5 includes a machine head mounting plate 51, which is provided with a feeding module 6 for conveying the crease strip 01, a pressure roller assembly 7 for bonding the crease strip 01 to the base plate 02, and a cutting module 8 for cutting the crease strip 01. The cutting module 8 includes a head cutting assembly 81 and a tail cutting assembly 82. The pressure roller assembly 7 is located between the head cutting assembly 81 and the tail cutting assembly 82 along the crease strip conveying direction. Both the head cutting assembly 81 and the tail cutting assembly 82 include a cutting blade 801 and a cutting power assembly for driving the cutting blade 801 to approach or move away from the crease strip 01.

[0036] The molding platform 1 is used to install the base plate 02. The molding platform 1 is equipped with a positioning component for positioning the base plate 02. The positioning component can be a positioning baffle, positioning post, etc. protruding from the mounting surface of the molding platform 1, or a positioning cylinder for abutting against the outer edge of the base plate 02.

[0037] Considering that the cutting directions of the cutting openings formed by the head-end cutting component 81 and the tail-end cutting component 82 are usually different, the head-end cutting component 81 will generate waste material that separates from the conveyed creasing strip 01 when cutting the creasing strip 01. The molding platform 1 is preferably equipped with a waste bin 11 for collecting waste material to prevent waste material from adhering to the base plate 02 or the machine head 5 and affecting the normal strip application and cutting operation of the machine head 5.

[0038] Meanwhile, the head 5 or the molding platform 1 is equipped with a waste removal component for cleaning up waste. For example, the waste removal component can be set as an air nozzle 9 on the head 5 and a negative pressure adsorption component on the molding platform 1, which uses pressure difference to blow or suck the waste into the waste bin 11. It can also be set as a gripper robotic arm to grab the waste and move it to the waste bin 11.

[0039] To reduce equipment costs, please refer to the following options. Figure 2 The outer edge of the molding platform 1 is provided with a waste bin 11 for collecting waste materials. The machine head mounting plate 51 is provided with an air nozzle 9 for blowing waste materials toward the waste bin 11. The air nozzle 9 is set directly opposite the cutting module 8 so as to blow the waste materials generated by cutting the head end of the indentation strip 01 into the waste bin 11.

[0040] Preferably, the blowing direction of the air nozzle 9 can be adjusted to achieve better waste collection results.

[0041] The head 5 is used to convey, bond and cut the creasing strip 01, and the feeding module 6 is used to convey the creasing strip 01. Since the adhesive side of the creasing strip 01 has a backing paper, it can be understood that the above conveying of the creasing strip 01 includes not only conveying the creasing strip 01, but also separating the backing paper of the creasing strip 01.

[0042] The feeding module 6 can be wound around the material tray 61 and feeds the creasing strip 01 forward by driving the rotation of the material tray 61. The back paper of the creasing strip 01 can be wound around the bottom paper receiving tray 641. The creasing strip 01 and the bottom paper can be separated by the rotation of the bottom paper receiving tray 641. Alternatively, the creasing strip 01 and the bottom paper can be separated by the separation hole, and then the separated bottom paper can be pulled away from the creasing strip 01 by the gripper and other power components.

[0043] The pressure roller assembly 7 is used to attach the crease strip 01 of the separating backing paper to the surface of the base plate 02. Considering that the material and thickness of the crease strip 01 required by different crease templates may be different, in order to improve the applicability of the pressure roller assembly 7, it is preferable to set the pressure of the pressure roller assembly 7 on the crease strip 01 to be adjustable. The pressure adjustment of the pressure roller assembly 7 is usually achieved by adjusting the height of the pressure roller assembly 7 relative to the base plate 02.

[0044] The height adjustment of the pressure roller assembly 7 can be achieved through linear power mechanisms such as electric push rods, cylinders and hydraulic cylinders, which have high adjustment accuracy. The power mechanism is connected to the control device, realizing automatic adjustment of the pressure of the pressure roller assembly 7.

[0045] For example, the pressure roller assembly 7 may include a pressure roller and a pressure roller cylinder. The pressure roller cylinder is mounted on the machine head mounting plate 51 via a pressure roller bracket. The pressure roller is located at the bottom of the cylinder rod of the pressure roller cylinder so that the height of the pressure roller can be adjusted by adjusting the pressure inside the cylinder, thereby adjusting the pressure of the pressure roller on the indentation strip 01.

[0046] The cutting module 8 is used to cut both ends of the crease strip 01 so that the length of the crease strip 01 is the same as the length of the corresponding crease line 03.

[0047] Considering that there are often two or more crease lines 03 intersecting at one point on the crease template, the cutting directions of the two ends of the crease strip 01 are usually different. In order to form cutting directions with different cutting directions, the cutting module 8 includes a head-end cutting component 81 for cutting the head end of the crease strip 01 and a tail-end cutting component 82 for cutting the tail end of the crease strip 01. The head end of the crease strip 01 refers to the end of the crease strip 01 that is first attached to the base plate 02, and the tail end of the crease strip 01 refers to the end of the crease strip 01 that is second attached to the base plate 02.

[0048] Both the head-end cutting assembly 81 and the tail-end cutting assembly 82 include a cutting blade 801 and a cutting power assembly for driving the cutting blade 801 relatively away from or close to the crease strip 01 to be cut; the cutting blade 801 is mostly configured as Figure 4 The V-shaped cutter shown has dimensions such as opening angle and thickness determined according to actual cutting needs. The cutting power component can be specifically set as a linear power mechanism such as a cutting cylinder 802, an electric push rod, or a hydraulic cylinder.

[0049] The installation directions of the head-end cutting assembly 81 and the tail-end cutting assembly 82 are determined based on the installation space of the machine head 5 and the cutting edge direction of the cutting blade 801 in actual production, so that the cutting edge of the cutting blade 801 can have a small contact area with the indentation strip 01 during cutting, thereby obtaining a larger cutting pressure under the premise that the power of the cutting power assembly is constant.

[0050] It should be noted that, in order to avoid the problem of cutting compensation at the head end of the crease strip 01, the head end of the crease strip 01 is usually cut first, and then the machine head 5 is moved by the machine head movement component to align the head end of the crease strip 01 with the head end of the crease line 03 to be pasted; therefore, the head end cutting component 81 presses the crease strip 01 onto the cutting plate 84 of the machine head 5, rather than pressing the crease strip 01 onto the base plate 02.

[0051] To prevent the cutting tray 84 from affecting the pressure roller assembly 7 in pressing the indentation strip 01 firmly onto the base plate 02, the cutting tray 84 is slidably mounted on the machine head mounting plate 51, or the cutting tray 84 is rotatably mounted on the machine head mounting plate 51, so that the cutting tray 84 can move between the cutting position and the pasting position, thus preventing the cutting tray 84 from affecting the normal operation of the pressure roller assembly 7.

[0052] During work, for a certain embossing line ab on the base plate 02 where embossing strip 01 needs to be pasted, for example... Figure 3 A crease line 03 with endpoints a and b is formed. The control device controls the head-end cutting component 81 to cut the crease strip 01. Here, the head-end cutting component 81 presses the crease strip 01 onto the cutting tray 84 of the machine head 5, rather than pressing the crease strip 01 onto the base plate 02. Then, the machine head movement component is controlled to move and rotate the machine head 5 so that the orientation of the machine head 5 is the same as the orientation of the crease line ab, and the endpoint of the cut crease strip 01 is aligned with one endpoint a of the crease line ab. Then, the machine head movement component is controlled to move the machine head 5 along the crease line ab, and the crease strip 01 is adhered to the base plate 02 along the extension direction of the crease line ab.

[0053] When the crease strip 01 moves to point b, the other end of the crease line ab, the control device controls the tail cutting component 82 to cut the crease strip 01, thereby completing the pasting of the crease strip 01 on the crease line ab.

[0054] It should be noted that, considering the possibility that cutting may cause the crease strip 01 to lose some length, in order to ensure that the crease strip 01 can completely cover the crease line ab, in actual work, the tail cutting point is usually set not to the endpoint b of the crease line ab, but rather to the point behind the endpoint b. point, Point b is located on the extension of the indentation line ab, and point b is on the line from point b to point b. Distance between points Cutting compensation amount It is usually a fixed value, and its value is related to the specific structure and size of the tail cutting component 82.

[0055] In this embodiment, the automatic embossing mold plate-making device realizes the automatic feeding, cutting and pasting of the embossing strip 01. Compared with manual cutting and pasting, the cutting and pasting efficiency is high, and the pasting direction and size control of the embossing strip 01 are more accurate, effectively improving the plate-making efficiency and plate-making accuracy.

[0056] Based on the above embodiments, the structure of the feeding module 6 is defined. The feeding module 6 includes a material tray 61 for winding the crease strip 01, a guide wheel 63, and a bottom paper receiving assembly for separating the bottom paper of the crease strip 01. The material tray 61 and the guide wheel 63 are rotatably mounted on the machine head mounting plate 51. The bottom paper receiving assembly is located between the material tray 61 and the pressure wheel assembly 7 along the crease strip conveying direction so that the crease strip 01 after separating the bottom paper is pressed and bonded to the surface of the base plate 02 by the pressure wheel assembly 7.

[0057] The material tray 61 is used to wind the indentation strip 01. It can be driven to rotate by the head motion component as the power source of the feeding module 6 and the friction of the pressure roller assembly 7 on the indentation strip 01. Alternatively, the material tray 61 can be connected to a servo motor and driven by the servo motor to feed the indentation strip 01 forward through its own rotation. In order to facilitate the adjustment of the feeding tension of the material tray 61, the material tray 61 is equipped with a tension adjustment component, which can be specifically set as a glass ball screw, a spring adjustment wheel, a magnetic powder brake, etc.

[0058] Guide wheel 63 is located on the transmission path of embossing strip 01 to guide the conveying direction of embossing strip 01; in order to facilitate the adjustment of the tension of embossing strip 01 and prevent slack in embossing strip 01 during conveying, which would affect conveying efficiency and the accurate cutting of embossing strip 01 by cutting module 8, feeding module 6 preferably has tension wheel 62, which is connected to tension adjustment component 66, such as Figure 1 As shown, the tension adjustment component 66 can adjust the tension of the tensioning wheel 62 on the indentation strip 01 to ensure that the indentation strip 01 remains taut during the conveying process.

[0059] The bottom paper assembly is located between the material tray 61 and the pressure roller assembly 7. It is used to separate the bottom paper of the crease strip 01 before pasting the crease strip 01. The bottom paper assembly can be driven by the same power source as the material tray 61, or the two can be driven by separate power sources.

[0060] Please refer to Figure 1 The bottom paper assembly includes a bottom paper tray 641 for winding the bottom paper, a drive pulley is sleeved on the rotating shaft of the tray 61, a driven pulley is sleeved on the rotating shaft of the bottom paper tray 641, and a bottom paper belt 642 is wound between the drive pulley and the driven pulley.

[0061] When the head movement assembly drives the pressure roller assembly 7 to move relative to the molding platform 1, the friction of the crease strip 01 drives the material tray 61 to rotate. The material tray 61 drives the drive pulley to rotate, which in turn drives the bottom paper belt 642 and the driven pulley to rotate. Finally, it drives the bottom paper tray 641, which is coaxially arranged with the driven pulley, to wrap the crease strip 01 around the bottom paper tray 641, thereby separating the crease strip 01 from the bottom paper.

[0062] In this embodiment, the feeding module 6 uses the material tray 61 and guide wheel 63 to transport and guide the crease strip 01, and works with the bottom paper assembly to separate the crease strip 01 and the bottom paper, thus realizing continuous transport of the crease strip 01. The structure is simple and occupies a small space, which is conducive to the miniaturization design of the machine head 5.

[0063] Based on the above embodiments, in order to avoid the crease strip 01 being subjected to force when separating the base paper and causing the crease strip 01 to deviate laterally, the feeding module 6 can be provided to also include a guide rail 65 for guiding and limiting the crease strip 01 after separating the base paper. The inner surface of the guide rail 65 is provided with an anti-stick coating to prevent the crease strip 01 from sticking together.

[0064] Please refer to Figure 1 The guide rail 65 extends in the conveying direction of the indentation strip 01. The specific shape and size of the guide rail 65 are determined according to the size of the indentation strip 01 in actual production, so that the guide rail 65 can meet the guiding and limiting requirements of the indentation strip 01 with the maximum allowable width.

[0065] When the difference between the maximum and minimum allowable width of the indentation strip 01 is large, it is preferable to set the width of the guide rail 65 to be adjustable, so as to avoid the guide rail 65 being unable to effectively limit the lateral movement of the smaller width of the indentation strip 01.

[0066] The width of the guide rail 65 is adjustable. The guide rail can be configured to include a guide rail base plate and guide rail baffles on both sides. At least one guide rail baffle and the guide rail base plate are slidably connected in the lateral direction so as to adjust the distance between the two guide rail baffles and thus adjust the width of the guide rail 65.

[0067] Of course, the guide rail 65 can also be detachably connected to the head mounting plate 51 so that guide rails 65 of different widths can be replaced to meet the guiding and limiting requirements of indentation strips 01 of different widths.

[0068] Guide rails 65 are typically made of stainless steel, carbon steel, or aluminum alloy, offering high strength, long lifespan, and ease of processing.

[0069] Considering that the adhesive side of the crease strip 01 is sticky after the backing paper is separated, in order to prevent the crease strip 01 from sticking to the inner surface of the guide rail 65 and affecting its continued forward conveying, the inner surface of the guide rail 65 is provided with an anti-stick coating. The anti-stick coating can be specifically set as a polytetrafluoroethylene coating, a KNM1000 anti-stick coating, a stainless steel honeycomb coating, etc.

[0070] In this embodiment, a guide rail 65 is provided between the bottom paper assembly and the pressure roller assembly 7. The guide rail 65 guides and limits the crease strip 01, which can prevent the crease strip 01 from shifting laterally during the separation of the bottom paper and also prevent the crease strip 01 from shifting laterally during the cutting process, thus ensuring the cutting accuracy of the crease strip 01 by the cutting module 8.

[0071] Preferably, the opening of the guide rail 65 is provided with a guide rail cover plate for limiting the height of the indentation strip 01. The guide rail cover plate is detachably connected to the guide rail 65, and the inner surface of the guide rail cover plate is provided with an anti-stick coating to prevent the indentation strip 01 from adhering to the inner surface of the guide rail cover plate.

[0072] The guide rail cover is mostly made of low-friction materials such as brass, UPE and other polymer plastics; the anti-stick coating on the inner surface of the guide rail cover can refer to the anti-stick coating on the inner surface of the guide rail 65 to reduce the anti-stick treatment process of the guide rail 65 and reduce the anti-stick treatment cost of the guide rail 65.

[0073] Based on the above embodiments, the structure of the cutting module 8 is defined. The cutting module 8 includes a vertically arranged cutting baffle 83 and a horizontally arranged cutting tray 84. The cutting tray 84 is connected to the tray power assembly so as to drive the cutting tray 84 to reciprocate between the cutting position and the pasting position.

[0074] When cutting the head end of the crease strip 01, the pallet power assembly controls the cutting pallet 84 to move towards the cutting baffle 83 so that the cutting pallet 84 abuts against the cutting baffle 83. The cutting power assembly drives the cutting blade 801 to move towards the crease strip 01 so as to press the crease strip 01 against the cutting pallet 84 and cut it.

[0075] Please refer to Figure 1 The cutting baffle 83 is located between the head cutting component 81 and the tail cutting component 82. The cutting baffle 83 can be used to limit the cutting tray 84 to prevent the cutting tray 84 from colliding with the tail cutting component 82. It can also be used to limit the creasing strip 01 to prevent the waste material generated by the head cutting from being too long and to save the material cost of the creasing strip 01.

[0076] The cutting baffle 83 can be fixed on the machine head mounting plate 51, or it can be connected to the cutting baffle 83 by sliding connection, rotation connection or other means. In order to simplify the connection structure of the cutting module 8 and facilitate the assembly of the cutting module 8 and the machine head 5, the cutting baffle 83 is usually fixed to the machine head mounting plate 51 by fasteners such as fastening screws and connecting pins.

[0077] The cutting tray 84 is used in conjunction with the head-end cutting component 81 to cut the indentation strip 01. In order to avoid damage to the cutting tray 84 during the cutting process and to improve the service life of the cutting tray 84, the cutting tray 84 needs to have high strength and toughness to meet the requirements of impact resistance and cutting performance. The cutting tray 84 can be made of high molecular plastics such as PA66 and reinforced POM.

[0078] The pallet power assembly is connected to the cutting pallet 84 and is used to drive the cutting pallet 84 to reciprocate between the cutting position and the pasting position; the pallet power assembly can be specifically configured as a linear power mechanism such as a pallet cylinder 85, a cylinder, or a hydraulic cylinder.

[0079] For example, please refer to Figure 2 The cutting tray 84 is connected to the cylinder rod of the tray cylinder 85. When the pressure inside the tray cylinder 85 increases, the cylinder rod extends outward and drives the cutting tray 84 to move closer to the cutting baffle 83, thereby moving the cutting tray 84 to the cutting position. Conversely, when the pressure inside the tray cylinder 85 decreases, the cylinder rod retracts inward and drives the cutting tray 84 to move away from the cutting baffle 83, thereby moving the cutting tray 84 to the pasting position.

[0080] In this embodiment, the cutting power assembly is used to drive the cutting tray 84 to move back and forth between the cutting position and the pasting position, which ensures both the normal cutting of the front cutting assembly 81 and the normal operation of the pressure roller assembly 7. The structure is simple and easy to adjust.

[0081] The cutting baffle 83 can limit the cutting tray 84 and the crease strip 01, which can limit the stroke of the cutting tray 84 and prevent the cutting tray 84 from colliding with the tail cutting component 82, and can also control the length of the waste material generated by the front cutting of the crease strip 01.

[0082] Preferably, to prevent the crease strip 01 from shifting due to cutting stress, the cutting tray 84 can be equipped with a brake block 651. When the cutting tray 84 moves to the cutting position, the brake block 651 abuts against the adhesive backing of the crease strip 01 to press the crease strip 01 tightly into the guide rail 65 and prevent the crease strip 01 from shifting during cutting.

[0083] Brake block 651 can be directly mounted on the cutting tray 84 or on the front axle plate of the tray cylinder 85; brake block 651 is preferably installed in a detachable manner to facilitate replacement of brake block 651.

[0084] In order to meet the clamping requirements of embossing strips 01 of different thicknesses, the brake block 651 should have a certain elasticity. It can be that the top of the brake block 651 that contacts the embossing strip 01 is provided with an elastic head such as a silicone head, or the brake block 651 can be connected to the cutting tray 84 through a spring, and the spring has an extension of the guide rail base plate perpendicular to the guide rail 65.

[0085] Based on the above embodiments, the structure of the head movement assembly is further defined; please refer to [reference needed]. Figure 1 The machine head motion assembly includes an X-axis motion assembly 2, a Y-axis motion assembly 3, and a machine head rotation assembly 4. The fixed end of the X-axis motion assembly 2 is connected to the mold-making platform 1, and the X-axis motion assembly 2 is used to drive the machine head 5 to move along the X-axis direction.

[0086] The fixed end of the Y-axis motion component 3 is connected to the moving end of the X-axis motion component 2. The Y-axis motion component 3 is used to drive the machine head 5 to move along the Y-axis direction.

[0087] The fixed end of the machine head rotation assembly 4 is connected to the moving end of the Y-axis motion assembly 3. The machine head rotation assembly 4 is used to drive the machine head 5 to rotate around the Z-axis.

[0088] Among them, the X-axis motion component 2 and the Y-axis motion component 3 are both linear motion components. They can be set as linear power mechanisms such as linear motors, cylinders and hydraulic cylinders to drive the guide rail slider mechanism, or they can be set as servo motors to drive the lead screw slider mechanism, worm gear mechanism, etc.

[0089] The specific types and control precision of the X-axis motion component 2 and the Y-axis motion component 3 are determined according to the actual production needs, and will not be elaborated here.

[0090] The machine head rotating assembly 4 is used to drive the machine head 5 to rotate around the main rotating shaft 52 in the horizontal plane, thereby adjusting the orientation of the indentation strip 01 in the feeding module 6 so that it is in the same direction as the extension of the indentation line 03 to be pasted.

[0091] The head rotation assembly 4 can be configured as a rotary motor 41, which directly drives the main rotating shaft 52 of the head 5 to rotate, or the rotary motor 41 drives the main rotating shaft 52 to rotate through a synchronous belt mechanism, sprocket mechanism or gear transmission mechanism, thereby driving the head 5 and the feeding module 6 installed on the head 5 to rotate, thereby changing the extension direction of the output indentation strip 01.

[0092] Please refer to Figure 1The machine head rotation assembly 4 includes a rotary motor 41. The output shaft of the rotary motor 41 is connected to the main rotary shaft 52, and the main rotary shaft 52 is connected to the machine head mounting plate 51. When the rotary motor 41 rotates, the output shaft of the rotary motor 41 drives the main rotary shaft 52 and the machine head mounting plate 51 to rotate synchronously, thereby realizing the orientation adjustment of the machine head 5.

[0093] Considering the needs of actual plate making, such as Figure 4 As shown, the rotation range of the main rotating shaft 52 is at least azimuth angle 0°-90°. The aforementioned azimuth angle refers to the angle between the projection of the indentation strip 01 of the machine head 5 in the mold making platform 1 and the X-axis direction. In order to facilitate the setting of the rotation origin of the machine head 5, it is preferable to set the rotation range of the main rotating shaft 52 to azimuth angle 0-180°. At this time, the angle between the projection of the indentation strip 01 in the mold making platform 1 and the X-axis direction can be an obtuse angle, which is beneficial to optimize the horizontal movement path of the machine head 5 and shorten the movement path to improve the plate making efficiency.
