Description

Technical Field

[0001] This invention relates to the field of packaging technology, and more specifically, to an automatic strip-cutting and creasing die-making device. Background Technology

[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 embossing 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 addition, resin plates can be made using 3D printing technology. Resin strips are printed sequentially on the indentation base plate and cured using a small ultraviolet light source. Finally, they are completely cured by a high-power ultraviolet light source to form an indentation template. Due to the influence of the printing process, the aspect ratio of the printed strips is limited. The aspect ratio of the printed strips cannot exceed 1:1.5, otherwise it will cause defects such as deformation and collapse of the strips. In addition, unstable printing pressure will make the size of the printed strips unstable, making it difficult to meet the size requirements of the indentation template.

[0019] The paper receiving module includes a paper receiving tray for winding the base paper with the indentation strip. The paper receiving tray is connected to the drive auxiliary wheel through a transmission assembly so that the drive auxiliary wheel drives the paper receiving tray to rotate.

[0021] Preferably, the punching power assembly includes a cutting blade cylinder arranged along the Z-axis direction, and the rotary power assembly includes a rotary cylinder arranged along the Z-axis direction and a sliding sleeve sleeved on the top end of the rotating shaft of the rotary cylinder.

[0022] The cutting blade cylinder has a rotating cutting blade shaft inside its cylinder body. The cutting blade is detachably mounted on the bottom end of the cutting blade shaft. The top end of the cutting blade shaft is slidably sleeved in the sliding sleeve. When the cutting blade cylinder drives the cutting blade to move up and down along the Z-axis, the cutting blade shaft slides up and down relative to the sliding sleeve along the Z-axis.

[0023] Preferably, the molding platform is provided with a vacuum adsorption component for adsorbing the indentation base plate and a positioning component for positioning the indentation base plate, wherein the positioning component is used to extend the indentation base plate along the X-axis and Y-axis directions.

[0024] Preferably, the machine head motion assembly includes an X-axis motion assembly for driving the machine head to reciprocate along the X-axis, a Y-axis motion assembly for driving the machine head to reciprocate along the Y-axis, a machine head lifting assembly for driving the machine head to reciprocate along the Z-axis, and a machine head rotating assembly for driving the machine head to rotate around the Z-axis.

Detailed Implementation

[0040] 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.

[0041] The core of this invention is to provide an automatic strip cutting and creasing mold making device, which realizes automatic cutting and pasting of creasing strips. Compared with manual cutting and pasting, the plate making efficiency and accuracy are high, and the aspect ratio of the creasing strip is not limited, making it widely applicable and able to meet the plate making requirements of creasing lines of various sizes.

[0042] It should be noted that 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 crease base plate 02 along the crease line 03. This would prevent the upper surface of the crease strips 01 from being no longer parallel to the crease 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.

[0043] The automatic strip-cutting creasing die-making device provided by the present invention includes:

[0044] The feeding module 7 includes a material tray 71 around which the indentation strip 01 is wound, a plurality of guide auxiliary rollers 72 for guiding the indentation strip 01, and a main pressure roller 78 for pressing the indentation strip 01 against the surface of the indentation base plate 02.

[0045] The paper receiving module 8, used to separate the bottom paper of the crease strip 01, is located between the material tray 71 and the main pressure roller 78 along the conveying direction of the crease strip;

[0046] The blanking module 9 includes a cutter 91, a blanking power assembly for driving the cutter 91 to move up and down along the Z-axis, and a rotary power assembly for driving the cutter 91 to rotate around the Z-axis.

[0047] The main mounting plate 61 of the die head, the feeding module 7, the paper receiving module 8 and the punching module 9 are all located on the main mounting plate 61 of the die head to form the die head 6;

[0048] The molding platform 1 includes a molding area 11 for positioning the indentation base plate 02 and a waste collection area 12 for collecting waste indentation strips 01;

[0049] The head motion assembly is used to control the movement of the head 6 relative to the molding area 11 along the X-axis and Y-axis, and to control the rotation of the head 6 relative to the molding area 11 around the Z-axis.

[0050] The control device, feeding module 7, paper receiving module 8, punching module 9, and head motion assembly are all connected to the control device via signals.

[0051] Please refer to Figure 1 The automatic die-making device for embossing includes a die-making platform 1 for positioning the embossing base plate 02, a head motion assembly for controlling the movement of the embossing strip 01 along the extension direction of the embossing line 03, and a head 6 for bonding and punching the embossing strip 01.

[0052] The molding platform 1 includes a molding area 11 for positioning the embossing base plate 02 and a waste collection area 12 for collecting waste embossing strips 01. The molding area 11 can position and fix the embossing base plate 02 of the embossing template by means of vacuum adsorption, pressing, etc. The embossing base plate 02 can be made of plastic materials such as PET and PVC, or it can be made of metal materials for flat pressing and flat die making, etc. The specific material of the embossing base plate 02 is determined according to the actual production needs, such as the type and purpose of the embossing template to be produced.

[0053] Waste collection area 12 is used to collect the discarded crease strips 01 after cutting, so as to prevent the discarded crease strips 01 from entering the molding area 11 and affecting the normal pasting and cutting of the crease strips 01; waste collection area 12 is usually set as a waste strip collection area.

[0054] To simplify the motion control of the machine head 6 in the horizontal plane, a machine head motion assembly is usually set to control the machine head 6 to move relative to the molding area 11 in a pair of orthogonal directions. In order to facilitate the control device to determine the component of the indentation line 03 in the above-mentioned orthogonal directions, an indentation base plate 02 is usually set to extend along the X-axis and Y-axis directions of the machine head motion assembly.

[0055] For example, please refer to Figure 2 and Figure 3 The molding platform 1 is equipped with a vacuum adsorption component for adsorbing the indentation base plate 02 and a positioning component for positioning the indentation base plate 02. The positioning component is used to extend the indentation base plate 02 along the X-axis and Y-axis directions.

[0056] For the specific directions of the X-axis and Y-axis for orthogonal settings, please refer to [link / reference]. Figures 1-3 As shown, the X-axis direction is usually parallel to the extension direction of the mold platform 1, and the Y-axis direction is parallel to the width direction of the mold platform 1.

[0057] To avoid the waste collection area 12 affecting the horizontal movement of the machine head 6, the waste collection area 12 is located on the left and right sides of the extending direction of the molding platform 1, and the waste collection area 12 needs to provide sufficient space for the movement of the X-axis motion assembly 2, such as... Figure 2 and Figure 3 As shown.

[0058] Please refer to Figure 2 and Figure 3 The waste collection area 12 includes a waste collection bar located on the outer edge of the mold making platform 1. The waste collection bar is connected to the mold making area 11 by detachable means such as bolt connection or pin connection, so that a new waste collection bar can be replaced after the waste collection bar is full of waste.

[0059] The machine head motion assembly can drive the machine head 6 to move relative to the molding area 11 along the X-axis and Y-axis directions, satisfying the requirements for applying the indentation line 03 inclined in the X-axis direction. It can be understood that the X-axis motion assembly 2, which controls the movement of the machine head 6 relative to the molding area 11 along the X-axis, and the Y-axis motion assembly 3, which controls the movement of the machine head 6 relative to the molding area 11 along the Y-axis, are independently controlled to ensure proper application of the indentation line 03. Figure 3 The indentation line ab shown represents the interpolation motion between the two.

[0060] Assuming the angle between a certain indentation line ab and the X-axis direction is β, then the moving speed Vx of the X-axis motion component 2 and the moving speed Vy of the Y-axis motion component 3 satisfy the following: ,like Figure 4 and Figure 5 As shown.

[0061] Both the X-axis motion component 2 and the Y-axis motion component 3 are linear motion components. They can be set to drive the guide rail slider mechanism with linear power mechanisms such as linear motors, cylinders and hydraulic cylinders, or they can be set to drive the lead screw slider mechanism, worm gear mechanism and so on with servo motors.

[0062] 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.

[0063] To ensure that the extension direction of the indentation strip 01 output by the feeding module 7 is the same as the extension direction of the indentation line ab of the corresponding sticker, the head motion assembly also includes a head rotation assembly for driving the head 6 to rotate relative to the molding area 11 along the Z-axis, thereby adjusting the azimuth angle of the indentation strip 01. The azimuth angle of the indentation strip 01 The angle between the embossing line ab and the embossing line ab same.

[0064] The machine head rotation assembly can be configured as a rotary motor 51, which directly drives the main rotating shaft 62 of the machine head 6 to rotate, or the rotary motor 51 drives the main rotating shaft 62 to rotate through a synchronous belt mechanism, sprocket mechanism or gear transmission mechanism, thereby driving the machine head 6 and the feeding module 7 installed on the machine head 6 to rotate, thereby changing the extension direction of the output indentation strip 01.

[0065] In order to make the crease strip 01 adhere to the crease base plate 02, the feeding module 7 is used to feed the crease strip 01 and use the main pressure roller 78 to press the crease strip 01 firmly to the crease base plate 02; the paper receiving module 8 is used to separate the back paper of the crease strip 01, so that the adhesive on the back of the crease strip 01 is exposed, so that the crease strip 01 can be adhered to the surface of the crease base plate 02 by the adhesive.

[0066] To facilitate the adjustment of the tension of the indentation strip 01, the material tray 71 is usually equipped with a tensioning component, which can be specifically configured as a ball screw, spring push rod, magnetic powder brake, etc.

[0067] To meet the bonding requirements of indentation strips 01 of different thicknesses, the position of the main pressure roller 78 relative to the main mounting plate 61 of the machine head can be set to be adjustable, or the height of the machine head 6 can be adjusted by setting a machine head lifting component, so as to adjust the height of the main pressure roller 78 relative to the indentation base plate 02 and thus adjust the feeding pressure of the main pressure roller 78.

[0068] To facilitate precise control of the conveying length of the indentation strip 01, the feeding module 7 is usually equipped with a brake cylinder assembly 73 and other braking components. The brake cylinder assembly 73 is used to achieve fixed-length conveying of the indentation strip 01 and to stop the indentation strip 01. Of course, fixed-length conveying of the indentation strip 01 can also be achieved by precisely controlling the rotation speed and working time of the material tray 71.

[0069] The feeding module 7 may not have a power source. It can use the head 6 to drive the main pressure roller 78 to move relative to the mold platform 1. The friction of the main pressure roller 78 on the embossing strip 01 drives the material tray 71 to rotate so as to convey the embossing strip 01 forward. Alternatively, the feeding module 7 may have a built-in power source. It can use a feeding motor or the like to drive the material tray 71 to rotate so as to convey the embossing strip 01 forward.

[0070] The specific structure and shape of the feeding module 7 can be determined by referring to existing belt material conveying devices based on actual production needs.

[0071] The specific structure and shape of the paper receiving module 8 can be set with reference to the adhesive strip separation mechanism in the existing technology according to actual production needs. For example, the paper receiving tray 81 can be used to rotate and peel off the back paper on the back of the creasing strip 01, or the main body of the creasing strip 01 and the back paper can be separated through different separation holes, and then the separated back paper can be pulled away from the main body of the creasing strip 01 by the power component.

[0072] After the embossing strip 01 is bonded to the embossing base plate 02 along the embossing line 03, it is necessary to cut the embossing strip 01 so that it can be cut off at both ends of the embossing line 03. The punching module 9 can cut the embossing strip 01 by the pressure of the cutter 91.

[0073] The structure and shape of the cutting edge of the cutting blade 91 determine the structure and shape of the cutting edge at the end of the indentation strip 01. The cutting angle of the cutting blade 91 is mostly set to 20°-25°.

[0074] The cutter 91 is usually set as a V-shaped cutter, and the cut angle formed by the V-shaped cutter is the same as the extension direction of the crease strip 01. The value of is determined based on the maximum number n of intersecting indentation lines 03 at a certain point within the indentation template (n≥1, and n is a positive integer). ;

[0075] In actual production, the number of intersecting indentation lines 03 at a certain point usually does not exceed 4, therefore the cutting angle of the V-shaped cutter is set. To avoid conflicts between the intersections of two or more crease lines 03 and the cut edges at the ends of crease strips 01, such as... Figure 4 As shown, the V-shaped angle γ of the V-shaped cutter is 60°-75°, and its corresponding cutting angle α is 30°-37.5°.

[0076] The punching power assembly is used to provide power for the lifting and lowering of the cutting blade 91. Specifically, it can be set as an electric push rod, a cylinder, or a hydraulic cylinder. The rotary power assembly is used to drive the cutting blade 91 to rotate around the Z-axis in order to adjust the cutting direction of the cutting edges at both ends of the indentation strip 01 and meet the distribution requirements of the indentation lines 03 of the indentation template. Specifically, the rotary power assembly can be set as a servo motor, a rotary cylinder 94, etc.

[0077] The control device is connected to the feeding module 7, the paper receiving module 8, the die-cutting module 9 and the head motion assembly to realize the automatic unfolding, bonding and cutting of the creasing strip 01, improve the bonding efficiency of the creasing strip 01, and thus improve the plate-making efficiency.

[0078] During work, for a certain embossing line ab on the embossing base plate 02 that requires a strip, such as... Figure 3 The crease line has two endpoints, a and b. The control device first controls the head movement assembly to move the head 6 above the waste collection area 12 of the mold platform 1. The control device then adjusts the head 6 to rotate around the Z-axis so that the orientation of the crease strip 01 of the feeding module 7 is the same as the extension direction of the crease line ab. Then, the control device moves the head movement assembly along the extension direction of the crease line ab so that the punching module 9 is aligned above the endpoint a of the crease line ab. During the above movement, the feeding module 7 and the paper receiving module 8 are used to bond the crease strip 01 to the surface of the crease base plate 02. Then, the control device lowers the cutting blade 91 of the punching module 9 along the Z-axis and cuts the crease strip 01 at point a. At this time, the crease strip 01 between the waste collection area 12 and point a is cut off and separated, becoming waste.

[0079] Then, the control head movement assembly moves along the extension direction of the crease line ab, so that the punching module 9 moves above the other end point b of the crease line ab. During the above movement, the feeding module 7 and the paper receiving module 8 bond the crease strip 01 to the surface of the crease base plate 02 along the crease line ab. The control rotation power assembly makes the cutter 91 rotate around the Z-axis so that the cutting direction at point b is different from the cutting direction at point a, which facilitates the subsequent application of other crease lines 03 such as crease line bc. The control of the cutter 91 of the punching module 9 is to descend along the Z-axis and cut the crease strip 01 at point b, thus completing the application of the crease line ab.

[0080] It should be noted that when the machine head 6 moves to point P above the waste collection area 12 of the molding platform 1, point P is located on the straight line where the indentation line ab is located, so as to ensure that when the machine head moving component drives the machine head 6 to move horizontally, the indentation strip 01 can be bonded to the surface of the indentation base plate 02 along the extension direction of the indentation line ab.

[0081] For an indentation template composed of several indentation lines 03, the control device can receive the imported indentation template graphic, calculate and obtain the starting point P of the movement of each indentation line 03, and generate corresponding program instructions to control the machine head movement component and the machine head 6 to complete the application of each indentation line 03 in a preset order. The preset order can be determined by the control device based on the minimum movement path, or it can be specified by the user.

[0082] In this embodiment, the feeding module 7 and the paper receiving module 8 realize the automatic feeding, backing paper separation and pasting of the creasing strip 01, the die-cutting module 9 realizes the automatic cutting of the creasing strip 01, and the machine head motion component realizes the effective control of the extension direction of the creasing strip, so that the creasing strip 01 can be accurately pasted on the surface of the creasing base plate 02 to form the corresponding creasing line 03. Compared with manual cutting and pasting, the plate making efficiency and plate making accuracy are high.

[0083] Meanwhile, the aspect ratio of the indentation strip 01 is not limited. Compared with the synthetic photocurable resin plate-making technology based on 3D printing technology, it has a wide range of applications and can meet the plate-making requirements of indentation lines 03 of various sizes.

[0084] Based on the above embodiments, in order to expand the stroke adjustment range of the cutting blade 91 of the blanking module 9, the head motion assembly is usually provided with a head lifting assembly for driving the head 6 to reciprocate along the Z-axis. The head lifting assembly can cooperate with the blanking power assembly of the blanking module 9 to form coarse and fine adjustments of the cutting blade 91. It can be that the blanking power assembly coarsely adjusts the height of the cutting blade 91 and the head lifting assembly finely adjusts the height of the cutting blade 91, or the head lifting assembly coarsely adjusts the height of the cutting blade 91 and the blanking power assembly finely adjusts the height of the cutting blade 91.

[0085] When the machine head moving assembly is equipped with a machine head lifting assembly, in order to avoid damage to the main pressure roller 78 due to excessive impact force during lifting, preferably, the main pressure roller 78 can be connected to the main mounting plate 61 of the machine head through a pressure roller seat 77. The pressure roller seat 77 is equipped with a buffer spring, one end of which is connected to the main mounting plate 61 of the machine head, and the other end of which is connected to the main pressure roller 78. The buffer spring absorbs the impact between the main pressure roller 78 and the indentation base plate 02, thereby improving the service life of the main pressure roller 78.

[0086] The aforementioned buffer spring is connected to the main pressure roller 78. Alternatively, the pressure roller seat 77 can be connected to the main mounting plate 61 of the machine head through the buffer spring. The pressure roller seat 77 transmits the pressure and impact on the main pressure roller 78 to the buffer spring, causing the buffer spring to be compressed.

[0087] Alternatively, the pressure roller seat 77 can be fixedly connected to the main mounting plate 61 of the machine head, and the rotating shaft mounting plate of the main pressure roller 78 can be slidably connected to the pressure roller seat 77. When the main pressure roller 78 is pressed, the pressure overcomes the elastic force of the buffer spring and drives the rotating shaft mounting plate of the main pressure roller 78 to slide relative to the pressure roller seat 77 in the Z-axis direction.

[0088] Based on the above embodiments, the feeding module 7 also includes a creasing strip guide rail 76 for guiding and limiting the creasing strip conveying direction. The creasing strip guide rail 76 is located between the paper receiving module 8 and the main pressure roller 78 along the creasing strip conveying direction. Both the main pressure roller 78 and the creasing strip guide rail 76 are located at the bottom of the main mounting plate 61 of the machine head.

[0089] Please refer to Figure 1 The creasing strip guide rail 76 is located between the paper receiving module 8 and the main pressure roller 78. It is used to guide and limit the creasing strip 01 after it separates from the backing paper and before it is pressed and bonded to the surface of the creasing base plate 02. This ensures that the orientation of the creasing strip 01 is the same as the extension direction of the corresponding creasing line 03, and prevents the creasing strip 01 from shifting after separating from the backing paper, which would affect the dimensional accuracy and quality of the creasing template.

[0090] The inner surface of the indentation strip guide rail 76 is provided with an anti-stick coating. The anti-stick coating is used to prevent the adhesive on the back of the indentation strip 01 from sticking to the indentation strip guide rail 76 and affecting the normal conveying of the feeding module 7. The anti-stick coating can be specifically set as a polytetrafluoroethylene coating, a KNM1000 anti-stick coating, a stainless steel honeycomb coating, etc.

[0091] Based on the above embodiments, in order to simplify the structure of the machine head 6, the guide auxiliary wheels 72 are distributed on the front and back sides of the indentation strip 01 along the conveying direction of the indentation strip, and at least one guide auxiliary wheel 72 is an active auxiliary wheel 74;

[0092] The paper receiving module 8 includes a paper receiving tray 81 for winding the bottom paper with the crease strip 01. The paper receiving tray 81 is connected to the drive auxiliary wheel 74 through a transmission assembly so that the drive auxiliary wheel 74 drives the paper receiving tray 81 to rotate.

[0093] The guide roller 72 is located on the conveying path of the embossing strip 01. The guide roller 72 is used to contact the embossing strip 01 to guide and limit the embossing strip 01, so as to prevent the embossing strip 01 from shifting laterally during the conveying process. At the same time, the guide roller 72 can keep the embossing strip 01 at a certain tension so as to prevent the embossing strip 01 from loosening and affecting the continuous and smooth conveying of the embossing strip 01.

[0094] The guide roller 72 can be provided on both the front and back sides of the crease strip 01. It can be understood that the guide roller 72 provided on the back side of the crease strip 01 is usually provided before the separation point of the back paper of the crease strip 01, so as to avoid the guide roller 72 from sticking to the adhesive of the crease strip 01 and affecting the conveying. Alternatively, an anti-stick coating can be provided on the surface of the guide roller 72, or the guide roller 72 can be made of an anti-stick material.

[0095] The quantity, material, structure, size, and distribution of the guide auxiliary wheels 72 are determined based on the structure, shape, and size of the main mounting plate 61 of the machine head in actual production.

[0096] Preferably, in order to facilitate the adjustment of the tension of the indentation strip 01 which is relatively far away from the material tray 71, the guide auxiliary wheel 72 which is relatively close to the main pressure wheel 78 can be set as a spring pressure wheel 75, so as to use the elastic force of the spring to achieve elastic pressing of the indentation strip 01, so as to ensure the smooth conveying of the indentation strip 01.

[0097] To reduce the number of power sources, it is preferable to use the guide auxiliary wheel 72 of the feeding module 7 to drive the paper receiving tray 81 to rotate. Please refer to [reference needed]. Figure 1 Ordinary guide auxiliary wheel 72 is mounted on one side of the main mounting plate 61 of the machine head via a rotating shaft, while the rotating shaft of the drive auxiliary wheel 74 protrudes from both ends of the main mounting plate 61 of the machine head, so that the aforementioned rotating shaft provides a drive auxiliary wheel 74 on one side of the main mounting plate 61 of the machine head, and cooperates with the transmission assembly on the other side of the main mounting plate 61 of the machine head, so as to drive the paper receiving tray 81 to rotate through the transmission assembly.

[0098] When the feeding motor of the feeding module 7 or the friction force of the creasing strip 01 drives the material tray 71 to rotate, the creasing strip 01 is continuously conveyed forward along the creasing strip conveying direction, which drives the active auxiliary wheel 74 in contact with the creasing strip 01 to rotate. The rotation of the shaft of the active auxiliary wheel 74 drives the conveying component, which in turn drives the paper receiving tray 81 to rotate, so that the bottom paper of the creasing strip 01 is separated.

[0099] The conveying component of the paper receiving module 8 can be specifically configured as a sprocket drive mechanism, a synchronous belt drive mechanism, etc.; when the conveying component is a synchronous belt drive mechanism, the paper receiving module 8 is provided with a tensioning component, which is used to adjust the tension of the synchronous belt in order to control the rotation speed of the paper receiving tray 81.

[0100] Of course, the paper receiving tray 81 can also be driven independently by a servo motor. The servo motor is usually connected to the paper receiving tray 81 through a reduction gear assembly.

[0101] In this embodiment, the paper receiving tray 81 is driven by the active auxiliary wheel 74 of the feeding module 7, eliminating the need for a separate power source for the paper receiving module 8. This results in low equipment cost and a simple structure.

[0102] Preferably, the transmission assembly includes a take-up belt 82, a drive pulley, and a driven pulley. The drive pulley is mounted on the shaft of the drive auxiliary pulley 74, and the driven pulley is mounted on the shaft of the take-up reel 81. The take-up belt 82 is wound around the drive pulley and the driven pulley, and the take-up belt 82 is provided with a tensioning component for adjusting the belt tension in order to control the rotation speed of the take-up reel 81 so that the rotation speed of the take-up reel 81 matches the rotation speed of the feed reel 71.

[0103] Based on the above embodiments, the structure of the punching module 9 is defined. The punching power assembly includes a cutting cylinder 92 arranged along the Z-axis direction, and the rotary power assembly includes a rotary cylinder 94 arranged along the Z-axis direction and a sliding sleeve 93 sleeved on the top of the rotating shaft of the rotary cylinder 94.

[0104] The cylinder body of the cutting blade cylinder 92 has a rotatable cutting blade shaft 921. The cutting blade 91 is detachably mounted on the bottom end of the cutting blade shaft 921. The top end of the cutting blade shaft 921 is slidably sleeved in the sliding sleeve 93. When the cutting blade cylinder 92 drives the cutting blade 91 to move up and down along the Z-axis, the cutting blade shaft 921 slides up and down relative to the sliding sleeve 93 along the Z-axis.

[0105] Among them, the cutting blade shaft 921 is the cylinder rod of the cutting blade cylinder 92. When the control device controls the air pressure of the cutting blade cylinder 92 to increase, the cutting blade shaft 921 descends along the Z-axis, thereby driving the cutting blade 91 to descend along the Z-axis until the cutting blade 91 completes the cutting of the indentation strip 01 and contacts the surface of the indentation base plate 02.

[0106] Conversely, when the control device controls the cylinder of the cutter cylinder 92 to decrease, the cutter shaft 921 rises along the Z-axis, causing the cutter shaft 921 and the cutter 91 to rise and reset along the Z-axis, preventing the cutter 91 from affecting the horizontal movement or rotation of the machine head 6.

[0107] When it is necessary to adjust the cutting direction of the cutter 91, the control device controls the rotary cylinder 94 to rotate. The rotating shaft of the rotary cylinder 94 drives the sliding sleeve 93 connected to it to rotate. The sliding sleeve 93 drives the cutter shaft 921, which is slidably connected to it, to rotate, thereby driving the cutter 91 at the bottom of the cutter shaft 921 to rotate synchronously. It should be noted that the height of the cutter shaft 921 and the cutter 91 remains unchanged during the above process.

[0108] 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 for driving the machine head 6 to reciprocate along the X-axis, a Y-axis motion assembly 3 for driving the machine head 6 to reciprocate along the Y-axis, a machine head lifting assembly for adjusting the machine head 6 to reciprocate along the Z-axis, and a machine head rotating assembly for driving the machine head 6 to rotate around the Z-axis. The fixed end of the X-axis motion assembly 2 is connected to the mold making platform 1, the moving end of the X-axis motion assembly 2 is connected to the fixed end of the Y-axis motion assembly 3, the moving end of the Y-axis motion assembly 3 is connected to the fixed end of the machine head lifting assembly, and the moving end of the machine head lifting assembly is connected to the fixed end of the machine head rotating assembly.

[0109] The machine head lifting assembly includes a Z-axis linear guide, a slider 42, and a lifting cylinder 41. The Z-axis linear guide is located at the moving end of the Y-axis motion assembly 3. The slider 42 is connected to the main mounting plate 61 of the machine head. The slider 42 is connected to the piston rod of the lifting cylinder 41 so as to drive the slider 42 to slide along the Z-axis linear guide. The lifting cylinder 41 is connected to the control device for signal connection.

[0110] The machine head rotation assembly includes a rotary motor 51. The output shaft of the rotary motor 51 is connected to the main rotation shaft 62 of the machine head 6 through a transmission assembly. The rotary motor 51 is signal-connected to the control device so that the control device can adjust the azimuth angle of the machine head 6 through the rotary motor 51, thereby adjusting the orientation of the indentation strip 01 relative to the molding platform 1.

[0111] In order to accurately control the automatic pasting and cutting process of the crease strip 01, it is preferable to set both the cutting cylinder 92 and the lifting cylinder 41 to be adjustable stroke cylinders. Among them, the lifting cylinder 41 can accurately adjust the height of the main pressure roller 78 and adjust the pressure of the main pressure roller 78 on the crease strip 01 according to the thickness of the crease strip 01.

[0112] The cutting cylinder 92 can work with the lifting cylinder 41 to precisely adjust the height of the cutting blade 91, so as to achieve precise cutting of the crease strip 01 and avoid over-cutting and damaging the crease base plate 02 below the crease strip 01.
