[0002] This invention also claims priority to Chinese patent application filed on October 28, 2025, with application number 2025222782230 and invention title "A Cutting Mechanism for a Cotton Applying Machine";
[0003] This invention also claims priority to Chinese patent application filed on October 28, 2025, with application number 2025222789598 and invention title "A Cotton Applying Machine";
[0004] The contents of the aforementioned Chinese patent application are incorporated herein by way of introduction. Technical Field
[0005] This invention relates to the field of strip application technology, and in particular to a strip application machine and method for a knife template. Background Technology
[0006] Flatbed die-cutting molds are widely used die-cutting tools in the packaging industry. They mainly consist of a base (cutting board), die material, creasing material, and elastic sheet material (such as cotton wool). The die material cuts the packaging material, and the creasing material creates indentations to meet the final product's forming requirements. To ensure smooth material release after die-cutting and protect the sharp blade, elastic sheet material (often cotton wool) is usually attached to both sides of the die material's blade, following its shape and certain rules. This elastic sheet material contracts under pressure during die-cutting, exposing the blade for cutting; after the pressure is released, it quickly springs back, achieving rapid demolding.
[0007] To overcome the drawbacks of manual strip application, automated strip application machines have emerged. Existing strip application machines first cut the spring cotton, then apply adhesive through a dispensing head along a predetermined path on a die template, and finally paste the cut spring cotton onto the adhesive-coated position on the die template. This method has the following problems: Low application efficiency: Existing equipment typically requires generating a separate dispensing path based on the shape of each piece of spring cotton. The dispensing head must move along this path and dispense adhesive segment by segment. This process involves a large amount of idle travel and start-stop actions, resulting in a long dispensing time and becoming a bottleneck for improving overall strip application efficiency; Poor application position accuracy and easy spring cotton displacement: The adhesives currently used in strip application machines generally have a slow curing speed. When the feed head places the spring cotton on the uncured adhesive, the spring cotton is in an unstable state. Under the pressure of subsequent application actions, or when squeezed or pulled during the application of adjacent spring cotton, the already applied spring cotton is prone to displacement or secondary displacement. This displacement directly causes the final position of the spring cotton to deviate from the set target position, seriously affecting the positional accuracy and consistency of the adhesive strip, and failing to meet the production requirements of high-precision die-cutting molds.
[0008] In conclusion, how to significantly improve the automation efficiency of the labeling process while ensuring labeling quality has become a pressing technical problem that needs to be addressed in this field. Summary of the Invention

[0078] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "X," "Y," and "Z" are used interchangeably with other directional terms. Figure 1 and Figure 3 The orientation is used as a reference.
[0079] See Figure 1-14 The present invention provides a strip applicator for a knife template, comprising a support platform, a heating unit, and an operating head.
[0080] A support platform is used to support the elastic sheet 8 and the cutting template 7. The elastic sheet 8 is cut to form several elastic strips 81 with hot melt adhesive on the bottom. A heating unit is used to melt the hot melt adhesive on the bottom of the elastic strips 81. An operating head is used to remove the elastic strips 81 from the elastic sheet 8, to move the removed elastic strips 81 above the heating unit and to space the hot melt adhesive on the bottom of the elastic strips 81 from the heating unit to melt the hot melt adhesive on the bottom of the elastic strips 81, and to move the elastic strips 81 with melted hot melt adhesive on the bottom to be pasted onto the strip position of the cutting template 7.
[0081] Based on the above configuration, this strip applicator is suitable for automated strip application of elastic strips 81 of any size and shape. It can melt the hot melt adhesive at the bottom of the elastic strip 81 via a heating unit and then adhere the elastic strip 81 to the die template 7. Therefore, this strip applicator has the following effects:
[0082] Eliminate the adhesive application process to improve strip application efficiency.
[0083] Improve the quality of the adhesive strip: The hot melt adhesive has quick-drying properties. When the elastic strip 81 is pasted to the knife template 7 after the hot melt adhesive at the bottom has melted, the hot melt adhesive can be quickly cured. This avoids the elastic strip 81 from being squeezed by the operating head or being squeezed or pulled during the pasting of adjacent elastic sheets 8, which would cause the attached elastic strip 81 to shift or shift again. This ensures the accuracy of the elastic strip 81 being pasted to the target position of the knife template 7.
[0084] It should be noted that during the heating process, the elastic strip 81 is arranged at intervals from the heating unit to prevent the elastic strip 81 from adhering to the heating unit.
[0085] Furthermore, the labeling method of this labeling machine includes the following steps:
[0086] S1. Provide an elastic sheet 8, which is cut to form a plurality of elastic strips 81 with hot melt adhesive on the bottom.
[0087] S2. Remove an elastic strip 81 with hot melt adhesive at the bottom from the elastic sheet 8.
[0088] S3. Move the elastic strip 81 above the heating unit and arrange the hot melt adhesive of the elastic strip 81 at intervals with the heating unit. The heating unit melts the hot melt adhesive at the bottom of the elastic strip 81 above.
[0089] S4. The elastic strip 81, after the hot melt adhesive at the bottom is melted, is pasted to the pasting position of the knife template 7 supported by the pasting table 3.
[0090] S5. Repeat steps S2-S4 until all the strip positions on the knife template 7 have been covered with elastic strips 81.
[0091] Preferably, the stripping machine also includes a frame 1, on which a support platform, a heating unit, and an operating head are all mounted.
[0092] Furthermore, the support platform includes a bearing platform 2 and a strip-applying platform 3. The bearing platform 2 is used to support the elastic sheet material 8, and the strip-applying platform 3 is used to support the die template 7.
[0093] Of course, the support platform 2 and the strip application platform 3 can be mounted on one frame 1, or they can be independently arranged on two frames 1. The support platform 2 and the strip application platform 3 can be separate platforms or planes that provide support.
[0094] Furthermore, the parameters of the hot melt adhesive used in this applicator are as follows:
[0095] Surface drying time is approximately 10 seconds. Melting point is 160-180℃. Main components include ethylene and vinyl acetate. Key characteristics include: it is a plastic adhesive; its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged; it is non-toxic, odorless, and an environmentally friendly chemical product. Because it is a solid, it is easy to package, transport, and store; it is solvent-free, pollution-free, and non-toxic. Furthermore, its production process is simple, it has high added value, and it offers strong and fast bonding.
[0096] Based on the inherent properties of this hot melt adhesive, it can be heated and melted and dries quickly, and its strong adhesion allows it to stably adhere the elastic strip 81 to the knife template 7.
[0097] Furthermore, the heating unit includes a heating plate 41, a blower 42, or a laser generator 43.
[0098] See Figure 6 Optionally, the heating unit includes a heating plate 41. The heating plate 41 can maintain a set heating temperature. In use, when the operating head moves the elastic strip 81 to a set distance above the heating plate 41 and maintains a set relative moving speed, the heating plate 41 can melt the hot melt adhesive at the bottom of the elastic strip 81 by thermal radiation.
[0099] See Figure 7 Optionally, the heating unit includes a hair dryer 42 with its nozzle facing upwards. In use, when the operating head moves the elastic strip 81 to a set distance above the hair dryer 42 and maintains a set relative moving speed, the hair dryer 42 can blow hot air toward the bottom of the elastic strip 81 to melt the hot melt adhesive at the bottom of the elastic strip 81.
[0100] The hair dryer model 42 can be selected as AT-A162D, with an output power of 1600W, a temperature range of 100℃-650℃, and an air flow rate of 200-500L / Min. Of course, the above is for reference only; other models of hair dryers 42 can also be used in actual applications.
[0101] See Figure 8 Optionally, the heating unit includes a laser generator 43, with the emitting end of the laser generator 43 facing upwards. When the operating head moves the elastic strip 81 to a set distance above the laser generator 43 and maintains a set relative moving speed, the emitting end of the laser generator 43 can emit a laser beam along the shape of the elastic strip 81 to melt the hot melt adhesive at the bottom of the elastic strip 81.
[0102] The laser generator 43 can be a MOPA-60W-2mJ model with a pulse width of 500ns, a frequency of 30kHz, a power of 100%, a speed of 5500mm / s, a back-and-forth filling method, a field lens model of F=210, a galvanometer model with a 12mm aperture, and a heating efficiency of 2s for a 9mm×90mm area. Of course, the above is for reference only; other models or power laser generators 43 can be used in actual applications, such as an 80-100W laser generator 43 to improve efficiency.
[0103] It should be noted that among the heating methods described above, the hair dryer 42 method allows for immediate use and has low energy consumption, but the internal components of the operating head are easily damaged by the wind force, and it can also disrupt the internal lubrication system. The laser generator 43 method offers high heating precision, but its cost is correspondingly higher. Furthermore, it requires real-time updates to the laser scanning path for different shapes of elastic strips 81, increasing the control complexity of the system. Additionally, it requires movement along the shape of the elastic strip 81 while emitting the laser, resulting in lower heating efficiency. In contrast, the heating plate 41 method is suitable for heating elastic strips 81 of various shapes and can maintain a constant heating temperature. It is easier to control and less expensive. Therefore, this application preferably uses the heating plate 41 method. Of course, the above is merely an example, and other heating methods can also be used. In actual use, different heating modes can be selected according to actual needs.
[0104] Specifically, the heating plate 41 is an electric heating plate 41, which can be set at any position on the frame 1 or can be set separately outside the frame 1.
[0105] It should be noted that, in practical applications, the heating temperature of the heating plate 41, the heating distance between the elastic strip 81 and the heating plate 41, and the heating time of the heating plate 41 on the elastic strip 81 can be flexibly set.
[0106] When the heating temperature is constant, the heating distance is directly proportional to the heating time; the closer the distance, the shorter the time. When the heating distance is constant, the heating temperature is inversely proportional to the heating time; the higher the temperature, the shorter the time. When the heating time is constant, the heating temperature is directly proportional to the heating distance; the higher the temperature, the farther the distance.
[0107] Preferably, the heating distance is set to be greater than 0 and less than or equal to 10 mm, and is generally set to 1 mm. The heating time is set to be greater than 0 and less than or equal to 5 seconds, and is generally set to 0.5 seconds. The heating temperature is preferably 400℃. The above settings are illustrative examples and not intended to be limiting; adjustments can be made accordingly in actual use.
[0108] Preferably, a temperature sensor is provided on the heating plate 41. When the temperature sensor detects that the heating plate 41 has reached the set heating temperature, the heating plate 41 can maintain the set heating temperature.
[0109] It should be noted that without a temperature sensor, during the application of strips to the template 7, a certain amount of time, such as 5 minutes, needs to be allowed before the application process to allow the heating plate 41 to reach its maximum temperature. For some smaller or simpler elastic strips 81, the cutting time may only be about 2 minutes. Therefore, after the elastic strip 81 is cut, it is necessary to wait about 3 minutes before heating. Furthermore, the melting temperature of the hot melt adhesive does not necessarily require the heating plate 41 to reach its maximum temperature. As a result, a lot of waiting time is wasted each time the strip is applied, and there is also a risk that the hot melt adhesive may melt due to excessive heating, thus affecting the quality of the application.
[0110] This application preferably includes a temperature sensor that can monitor the surface temperature of the heating plate 41 in real time. When the set heating temperature is reached, the plate can be kept warm, for example, when the temperature reaches 200°C or lower. Factory tests show that it takes about 25 seconds to reach 100°C and about 1 minute to reach 200°C. After the elastic strip 81 is cut, it can be continuously heated after a short wait or without waiting.
[0111] See Figure 9 Specifically, the size of the heating plate 41 can be set such that the projection of any size and shape of elastic strip 81 to be pasted on the template 7 falls within the range of the heating plate 41, making it suitable for heating elastic strips 81 of any size and shape. In use, when the operating head moves the elastic strip 81 above the heating plate 41 and the hot melt adhesive at the bottom of the elastic strip 81 is spaced apart from the heating plate 41, the operating head moves at zero speed relative to the heating plate 41, i.e., it remains stationary relative to the heating plate 41, and remains stationary for a set time, allowing the heating plate 41 to melt all the hot melt adhesive at the bottom of the elastic strip 81 at once. This configuration improves heating efficiency and applicability, but it correspondingly increases the width of the entire device, and the cost also increases accordingly, including production and transportation costs.
[0112] Preferably, based on the above-mentioned size settings of the heating plate 41, the heating temperature, heating distance and heating time of the heating plate 41 are set to be constant for all the elastic strips 81 that need to be pasted on the one-cut template 7, so as to reduce the difficulty of adjustment.
[0113] See Figure 10Specifically, the size of the heating plate 41 can be set such that the projection of at least one of the elastic strips 81 to be pasted on the heating plate 41 extends beyond the range of the heating plate 41. In use, when the projection of an elastic strip 81 above the heating plate 41 extends beyond the range of the heating plate 41, the operating head remains stationary relative to the heating plate 41 and maintains a set heating time. Then, the operating head moves the elastic strip 81 away from the heating plate 41, allowing the heating plate 41 to gradually melt all the hot melt adhesive at the bottom of the elastic strip 81. Of course, for elastic strips 81 whose projection falls within the range of the heating plate 41, the heating plate 41 can still melt all the hot melt adhesive at the bottom of the elastic strip 81 in one go. While this configuration reduces heating efficiency, it allows control over the overall width of the equipment, and costs, including production and transportation costs, are reduced accordingly.
[0114] Preferably, based on the above-described dimensions of the heating plate 41, the heating time when the elastic strip 81 moves relative to the heating plate 41 at a set speed is longer than the heating time when the heating plate 41 is stationary relative to the heating plate 41. In use, the heating temperature and heating distance of the heating plate 41 are kept constant, and the heating time is adjusted accordingly.
[0115] Preferably, in order to shorten the travel of the operating head and improve the strip application efficiency, this embodiment further specifies that: the heating plate 41 is fixed between the support platform 2 and the strip application platform 3, and arranged in the same direction as the moving path of the operating head, so that the operating head can take the elastic strip 81 out from the elastic sheet 8 on the support platform 2 and drive it to move to the strip application platform 3 after being heated by the heating plate 41.
[0116] See Figure 11 and 12 Preferably, to further shorten the travel distance of the operating head and further improve the strip application efficiency, in this embodiment, the support platform 2 and the strip application platform 3 are arranged at intervals along a first direction (such as the X-axis direction), and the heating plate 41 is disposed between the support platform 2 and the strip application platform 3. The heating plate 41 is movably mounted on the frame 1 along a second direction (such as the Y-axis direction) so as to adjust the position of the operating head in real time according to the current cotton picking position on the support platform 2 and the current strip application position B on the strip application platform 3.
[0117] The heating plate 41 can be moved so that the center C of the heating plate is collinear with the center of the current elastic strip removal position A on the support platform 2 and the center of the current strip application position B on the strip application platform 3, so that the total idle distance of the operating head during the movement between the three work stations of the support platform 2, the heating plate 41 and the strip application platform 3 is minimized.
[0118] In order to achieve the movable arrangement of the heating plate 41, a guide rail extending along the moving trajectory of the heating plate 41 is arranged on the frame 1, and the heating plate 41 is placed on a slider, which is slidably placed on the guide rail.
[0119] In use, the heating plate 41 on the slide can be moved by the slider based on the coordinates of the elastic strip removal position A on the support platform 2 and the current strip application position B on the strip application platform 3.
[0120] Preferably, the top of the heating plate 41 is covered with an anti-stick layer, which can prevent the elastic strip 81 from sticking to the heating plate 41 when it comes into contact with the heating plate 41 due to its large size or poor grip.
[0121] See Figure 6 Preferably, the tape applicator further includes a correction platform 6 mounted on the frame 1, with the top of the correction platform 6 being a flat surface.
[0122] The operating head is also used to move the elastic strip 81 to the top of the correction platform 6 to perform horizontal correction on the elastic strip 81, and can move the corrected elastic strip 81 above the heating unit to improve the strip application quality of the knife template 7.
[0123] Preferably, the labeling machine also includes a control system.
[0124] The control system is connected to the operating head and is used to control the movement of the operating head; or,
[0125] The control system is connected to the operating head and the heating unit, and is used to simultaneously control the movement of the operating head and the heating of the heating unit.
[0126] Example 2
[0127] This embodiment is a further limitation based on Embodiment 1, and this embodiment protects a strip-removing and pasting mechanism.
[0128] See Figure 1-3 The labeling machine includes a frame 1, a first XY axis guide rail 51 mounted on the frame 1, and a first slide table 52 slidably mounted on the first XY axis guide rail 51.
[0129] The operating head is located on the first slide table 52 and can move along the first XY axis guide rail 51 to the support table 2, the heating unit and the strip application table 3.
[0130] Specifically, the operating head includes a material handling head 512.
[0131] The pick-and-place head 512 is used to remove the elastic strip 81 from the elastic sheet 8, move the removed elastic strip 81 through the heating unit to melt the hot melt adhesive at the bottom of the elastic strip 81, and then move the elastic strip 81 with the melted hot melt adhesive at the bottom to stick it to the strip position of the die template 7.
[0132] Specifically, a sliding plate is slidably mounted on the first XY axis guide rail 51, and the specific structure and working principle of the pick-and-place head 512 are the same as in Embodiment 3. The mounting base plate 5121 of the pick-and-place head 512 is fixedly mounted on the sliding plate to adjust its height.
[0133] It should be noted that the elastic strips 81 on the elastic sheet 8 are first cut by an independent waterjet machine or other cutting equipment, and then the cut elastic sheet 8 is placed on the support table, and then the operating head picks up the material and attaches the strips.
[0134] Example 3
[0135] This embodiment is a further refinement based on Embodiment 2. This embodiment protects an integrated machine for cutting, taking out, and gluing strips.
[0136] See Figure 1-2 13-17, the operating head includes a first operating head 53. The first operating head 53 is movable to the support table 2, the heating unit, and the strip attaching table 3. The first operating head 53 is used to cut the elastic sheet 8 into elastic strips 81 of arbitrary size and shape and remove the elastic strips 81 from the elastic sheet 8, and to move the elastic strips 81 to the cutting template 7 after the hot melt adhesive at the bottom of the elastic strips 81 is melted by the heating unit.
[0137] Thus, the first operating head 53 integrates the functions of cutting the elastic sheet 8, removing the elastic strip 81, heating the elastic strip 81, and pasting the elastic strip 81 into one machine head, and sequentially performs the cutting, removing, and pasting processes to reduce the size of the machine head and simplify the structure, thereby reducing the overall size of the device and simplifying the structure.
[0138] Based on the above settings of this embodiment, the strip application method of this strip application machine includes the following steps:
[0139] S11, the first operating head 53 cuts the elastic sheet 8 supported by the support platform 2 into elastic strips 81 of arbitrary size and shape.
[0140] S12, the first operating head 53 moves the elastic strip 81 above the heating unit and arranges the hot melt adhesive of the elastic strip 81 and the heating unit at intervals, and the heating unit melts the hot melt adhesive at the bottom of the elastic strip 81.
[0141] S13, the first operating head 53 drives the elastic strip 81, after the hot melt adhesive at the bottom is melted, to stick to the sticking position of the knife template 7 carried by the sticking table 3.
[0142] S14. Repeat steps S11-S13 until all adhesive positions on the knife template 7 have been covered with elastic strips 81.
[0143] Based on the above setup, the entire process from cutting, picking, heating to pasting of the elastic sheet 8 is completed automatically by machinery without the need for manual intervention in the connection between each step, resulting in a smooth and continuous operation.
[0144] Specifically, step S11 further includes: heating the heating unit to a set heating temperature.
[0145] Preferably, step S11 further includes, after the first operating head 53 removes the elastic strip 81 from the elastic sheet 8, moving the elastic strip 81 to the top of the correction platform 6 to correct the horizontal alignment of the elastic strip 81.
[0146] Specifically, the first operating head 53 includes a cutting head 510 and a material handling head 512.
[0147] Optionally, the cutting head 5103 of the cutting head 510 can be inserted into the elastic sheet 8 by vibrating up and down, and can move relative to the elastic sheet 8 along the X-axis and Y-axis and rotate around the vertical axis to adjust the orientation of the cutting edge, so as to cut the elastic sheet 8 into elastic strips 81 of arbitrary size and shape. Of course, the cutting head 510 can also be configured with other structural forms, as long as it can cut the elastic sheet 8 into elastic strips 81 of arbitrary size and shape.
[0148] The pick-and-place head 512 is used to remove the elastic strip 81 from the elastic sheet 8, move the removed elastic strip 81 through the heating unit to melt the hot melt adhesive at the bottom of the elastic strip 81, and then move the elastic strip 81 with the melted hot melt adhesive at the bottom to stick it to the strip position of the die template 7.
[0149] Preferably, the first operating head 53 further includes a positioning head 511. The positioning head 511 is used to scan and detect the height and position of the blade template 7 carried by the labeling table 3 relative to the labeling table 3.
[0150] Based on the above settings, the labeling method of this labeling machine includes the following steps:
[0151] A1. Place the knife template 7 on the strip application table 3, and use the positioning head 511 to scan and detect the position and height of the knife template 7 relative to the strip application table 3.
[0152] A2. Place the elastic sheet 8 on the support table 2, and the cutting head 510 cuts the elastic sheet 8 into an elastic strip 81 of the required shape and size.
[0153] A3. The material handling head 512 takes the elastic strip 81 out of the elastic sheet 8 and moves the elastic strip 81 to the top of the heating unit, and arranges the hot melt adhesive of the elastic strip 81 and the heating unit at intervals. The heating unit melts the hot melt adhesive at the bottom of the elastic strip 81.
[0154] A4. The feeding head 512 drives the elastic strip 81, which is made of hot melt adhesive at the bottom, to stick to the sticking position of the knife template 7 supported by the sticking table 3.
[0155] A5. Repeat steps A1-A4 until all the strip positions on the knife template 7 have been covered with elastic strips 81.
[0156] Preferably, step A3 further includes taking an elastic strip 81 out of the elastic sheet 8 by the material pick-and-place head 512, moving the elastic strip 81 to the top of the correction platform 6 to correct the horizontal deviation of the elastic strip 81, and then moving the elastic strip 81 above the heating unit.
[0157] Furthermore, the first operating head 53 is mounted on the first slide table 52. The first operating head 53 can move along the first XY axis guide rail 51 to the support table 2, the heating unit, or the strip application table 3.
[0158] Specifically, the positioning head 511, the cutting head 510, and the material handling head 512 are all independently mounted on the first slide table 52.
[0159] See Figure 17 More specifically, the positioning head 511 includes:
[0160] The detection base plate 5111 is fixedly mounted on the first slide table 52.
[0161] The detection slide 5112 is movably mounted on the detection base plate 5111 so that the entire positioning head 511, except for the detection base plate 5111, can be raised and lowered relative to the first slide 52 to adjust its height.
[0162] The detection motor 5113 is fixed on the detection base plate 5111, and the output shaft of the detection motor 5113 is fixedly connected to the detection slide 5112.
[0163] The first rotary cylinder 5114 is fixedly connected to the detection slide 5112 and is horizontally arranged.
[0164] The first rotary cylinder 5115 is fixedly connected to the rotating end of the first rotary cylinder 5114, and the output shaft of the first rotary cylinder 5115 is horizontally set.
[0165] The detection rod 5116 is fixedly connected to the output shaft of the first rotary cylinder 5115.
[0166] As a further improvement, one end of the detection rod 5116 is provided with a probe 5117, and the other end of the detection rod 5116 is provided with a roller 5118.
[0167] When detecting the cutter seam position of the die template 7, the probe 5117 slides across the cutter seam of the die template 7. During this process, the detection head at the tip of the probe 5117 gradually enters and leaves the cutter seam. The height of the detection head changes depending on the contact position with the cutter seam. This is synchronously driven by the detection rod 5116 to rotate the first rotary cylinder 5115, causing an angular change in the rotation axis of the first rotary cylinder 5115 relative to its initial position. The angular change curve is read, and the peak of the curve corresponds to the lowest value of the detection head height. The XY value of the detection head corresponding to this lowest value is a point on the centerline of the cutter seam. Repeated scrolling obtains the centerline parameters of the cutter seam. The centerline parameters of at least two intersecting cutter seams are obtained and compared with the cutter seam parameters on the die template in the database embedded in the equipment to obtain the actual position of the current die template and cutter seam.
[0168] When detecting the blade height of the blade template 7, the rolling wheel 5118 rolls on the blade. The height of the rolling wheel 5118 changes according to the blade height. This change in height of the rolling wheel 5118 synchronously drives the rotating shaft of the first rotary cylinder 5115 to rotate via the detection rod 5116. The rotating shaft of the first rotary cylinder 5115 changes angle relative to its initial position. By reading the angle change curve, the actual parameters of the blade height at different positions are obtained, thereby determining whether the blade height meets the requirements.
[0169] See Figure 13-14 More specifically, the cutting head 510 includes:
[0170] The tool holder 5101 is driven to vibrate up and down by the driving element 5102.
[0171] A cutting head 5103 is detachably mounted at the bottom of the cutter holder 5101.
[0172] The first rotary base 5104 and the cutter holder 5101 are rotatably and vertically vibrating on the first rotary base 5104. The cutter holder 5101 can drive the cutting head 5103 to rotate relative to the first rotary base 5104 around a vertical axis to adjust the blade orientation of the cutting head 5103 and change the cutting direction of the cutting head 5103. The cutter holder 5101 can also drive the cutting head 5103 to vibrate vertically relative to the first rotary base 5104.
[0173] A first motor 5105 drives a cutter holder 5101 to rotate around a vertical axis, which in turn drives the cutting head 5103 to rotate synchronously. Both the drive end of the first motor 5105 and the cutter holder 5101 are equipped with synchronous pulleys, and a first synchronous belt 51051 is fitted onto the two synchronous pulleys. When the drive end of the first motor 5105 rotates, it drives the cutter holder 5101 to rotate around the vertical axis through the transmission between the synchronous pulleys and the first synchronous belt 51051.
[0174] The first pressure plate 5106 is elastically disposed at the bottom of the first rotary seat 5104 and can be moved up and down. The first pressure plate 5106 has a window 5107 in the middle and the cutting head 5103 is located in the window 5107.
[0175] The drive element 5102 is a vibration motor or a pneumatic component. A vibration motor or a pneumatic component can be selected according to the application requirements. Of course, other drive elements that can drive the tool holder 5101 to vibrate up and down can also be used.
[0176] The second operating head 560 also includes a cutting bracket 5108, which is fixedly mounted on the first slide table 52. The cutting bracket 5108 has a cutting base plate 5109 that is driven to move up and down by a second motor 5110. A first rotary seat 5104 is fixed to the cutting base plate 5109. When the second motor 5110 operates, it can drive the first rotary seat 5104 to rise or fall relative to the first slide table 52 to adjust the height position of the cutting head 5103.
[0177] In this embodiment, when the first pressure plate 5106 presses down on the elastic sheet 8 to be cut, if the cutter holder 5101 continues to press down, the distance between the first pressure plate 5106 and the first rotary seat 5104 will shorten as the pressure reaches a certain level, and the cutting head 5103 will insert into the elastic sheet 8. The driving element 5102 drives the cutter holder 5101 to vibrate up and down, thereby causing the cutting head 5103 to vibrate up and down. When the cutting head 5103 is inserted into the elastic sheet 8 with up and down vibration, the cutting head 5103 can move relative to the elastic sheet 8 along the X-axis and Y-axis, and the cutting head 5103 can rotate around the vertical axis to adjust the blade orientation of the cutting head 5103 and change the cutting direction of the cutting head 5103. Thus, the cutting of the elastic sheet 8 can be achieved.
[0178] The movement of the first slide 52 along the first XY axis guide rail 51 can drive the cutting head 5103 to move relative to the elastic sheet 8 along the Y axis. The bearing platform 2 drives the elastic sheet 8 to move along the X axis guide rail 21, which can realize the movement of the elastic sheet 8 relative to the cutting head 5103 along the X axis.
[0179] See Figure 15-16 More specifically, the material handling head 512 includes:
[0180] Mounting base plate 5121 is fixedly mounted on first slide table 52. Slide table 5128 is provided on mounting base plate 5121 that can move up and down.
[0181] The material handling motor 5122 has its output shaft connected to the slide table 5128, which is used to drive the slide table 5128 to move up and down.
[0182] Rotary fixed base 5123 is fixedly connected to slide table 5128.
[0183] The material handling body 5124 is rotatably mounted on the rotating fixed base 5123.
[0184] Pin assembly 5125 is disposed at the bottom of the material handling body 5124.
[0185] The stripping plate 5126 is driven by the discharge cylinder 5130 and is disposed below the material handling body 5124. The stripping plate 5126 has a first clearance position corresponding to the pin on the pin assembly 5125.
[0186] The pressure plate 5127 is driven by the pressure cylinder 5129 and is movable up and down below the material handling body 5124. The pressure plate 5127 has a second clearance position corresponding to the stripping plate 5126.
[0187] The discharge cylinder 5130 is located at the top of the material handling body 5124. A connecting rod is provided through the material handling body 5124. One end of the connecting rod is connected to the cylinder shaft of the discharge cylinder 5130, and the other end of the connecting rod is connected to the stripping plate 5126.
[0188] It also includes a material handling rotary motor 5131, which is fixedly connected to the rotary fixed base 5123.
[0189] Both the rotating shaft of the material-picking rotary motor 5131 and the material-picking / discharging body 5124 are equipped with synchronous pulleys, and a second synchronous belt 5132 is fitted onto the two synchronous pulleys. When it is necessary to select the angle of the pin assembly 5125, the material-picking rotary motor 5131 operates, driving the material-picking / discharging body 5124 to rotate through the second synchronous belt 5132, thereby realizing the deflection of the pin assembly 5125.
[0190] When it is necessary to grasp the elastic sheet 8 below, the pin moves downward according to the program-set direction. The picking motor 5122 drives the slide table 5128 to move downward, thereby moving the rotating fixed seat 5123 mounted on the slide table 5128. The picking and dispensing body 5124 moves downward as well, so that the pin is inserted into the elastic sheet 8. The pressing cylinder 5129 drives the pressing plate 5127 to move downward. The pressing plate 5127 presses on other elastic sheets 8 that do not need to be grasped, preventing other elastic sheets 8 from moving upward after the grasped elastic sheet 8. The picking motor 5122 drives the slide table 5128 to move upward, and the pin moves upward with it. The elastic sheet 8 on the pin also moves upward. Due to the action of the pressing plate 5127, other elastic sheets 8 that are not grasped remain in their original positions.
[0191] When the material handling head 512 moves to the position above the elastic sheet 8 that needs to be attached to the flat die, the elastic sheet 8 needs to be lowered. The material handling cylinder 5130 is activated, the cylinder shaft of the material handling cylinder 5130 extends, and the connecting rod moves downward, so that the stripper plate 5126 pushes the elastic sheet 8 on the pin downward, so that the elastic sheet 8 is pressed against the die template.
[0192] Preferably, the first XY axis guide rail 51 adopts a lead screw guide rail to ensure the movement accuracy of the first operating head 53.
[0193] Example 4
[0194] This embodiment is a further refinement based on Embodiment 1. This embodiment protects a split-type strip applicator, which has independently arranged mechanisms for cutting and for picking up and applicating materials.
[0195] See Figure 3-5 , Figure 18 The operating head includes a second operating head 56 and a third operating head 59. The second operating head 56 is used to cut the elastic sheet 8 supported by the support platform 2 into elastic strips 81 of arbitrary size and shape. The third operating head 59 can move to the support platform 2, the heating unit, and the strip application table 3. The third operating head 59 is used to remove the elastic strip 81 from the elastic sheet 8 and, by driving the elastic strip 81 through the heating unit to melt the hot melt adhesive at the bottom, apply it to the cutting template 7.
[0196] Therefore, this application employs two operating heads, a second operating head 56 and a third operating head 59. The second operating head 56 independently performs the cutting process, while the third operating head 59 independently performs the processes of picking up the elastic strip 81, heating, and pasting. This allows the two processes of cutting the elastic sheet 8 and pasting the elastic strip 81 to be performed simultaneously. Compared to the pasting mechanism where cutting the cotton and pasting the elastic sheet 8 are done sequentially, this embodiment eliminates the waiting time for cutting the cotton, thereby effectively improving the overall working efficiency of the pasting machine. Specifically, the second operating head 56 specializes in high-speed, precise cutting and can operate continuously, producing elastic strips 81 without interruption. The third operating head 59 specializes in picking up materials, positioning, and precise pasting, cyclically performing the actions of picking up the cotton, heating, and pasting.
[0197] Specifically, the number of second operating heads 56 is at least one. When multiple second operating heads 56 are provided, multiple second operating heads 56 can cut multiple elastic sheets 8 simultaneously to improve cutting efficiency.
[0198] Furthermore, the support platform 2 is capable of moving the elastic sheet 8 to be cut to the cutting station Q1, and moving the cut elastic sheet 8 to the unloading station Q2. The second operating head 56 is used to cut the elastic strip 81 from the elastic sheet 8 supported by the support platform 2 at the cutting station Q1. The third operating head 59 is used to remove the elastic strip 81 from the elastic sheet 8 supported by the support platform 2 at the unloading station Q2.
[0199] The number of carrier platforms 2 is at least one. When the number is at least two, the at least two carrier platforms 2 can move independently of each other; or, the at least two carrier platforms 2 can move synchronously and are located at the cutting station Q1 and the material picking station Q2 respectively (i.e., part of the carrier platform 2 is located at the cutting station Q1 and part of the carrier platform 2 is located at the material picking station Q2).
[0200] Since the cutting action of the second operating head 56 and the elastic strip picking action of the third operating head 59 are located at the cutting station Q1 and the picking station Q2 respectively, they do not interfere with each other and can be carried out simultaneously. After the second operating head 56 finishes cutting the elastic sheet 8 on at least one support platform 2 located at the cutting station Q1, when the second operating head 56 performs the cutting operation on the remaining elastic sheets 8 on the support platforms 2 located at the cutting station Q1, the third operating head 59 can simultaneously cycle through the operations of picking out the elastic strip 81, heating the elastic strip 81, and pasting the elastic strip 81 to speed up the pasting efficiency and eliminate the waiting time for cutting. Of course, after all the elastic strips 81 in the elastic sheets 8 on the support platforms 2 located at the picking station Q2 have been picked out, new elastic sheets 8 can be replaced, and the support platforms 2 can drive the new elastic sheets 8 to move back to the cutting station Q1 for the second operating head 56 to cut.
[0201] Specifically, based on the above settings, the labeling method of this labeling machine includes the following steps:
[0202] S21. A batch of multiple elastic sheets 8 to be cut are placed one-to-one on multiple support tables 2 located at the cutting station Q1. The second operating head 56 cuts at least one elastic sheet 8 supported by a support table 2 into multiple elastic strips 81 of arbitrary size and shape. The support table 2 moves the cut elastic sheet 8 to the material picking station Q2.
[0203] S22, the second operating head 56 cuts the elastic sheet 8 carried by the other or sequentially other bearing platforms 2 into multiple elastic strips 81 of arbitrary size and shape. The bearing platform 2 moves the cut elastic sheet 8 to the material handling station Q2. At the same time:
[0204] S221, the third operating head 59 removes the elastic strip 81 from the cut elastic sheet 8 and moves the elastic strip 81 above the heating unit, and arranges the hot melt adhesive of the elastic strip 81 and the heating unit at intervals. The heating unit melts the hot melt adhesive at the bottom of the elastic strip 81. Then, the third operating head 59 pastes the elastic strip 81 with the melted hot melt adhesive at the bottom onto the strip pasting position of the knife template 7 carried by the strip pasting table 3.
[0205] S222. Repeat step S221 until all the strip positions on the knife template 7 have been covered with elastic strips 81.
[0206] Specifically, step S21 further includes: heating the heating unit to a set heating temperature.
[0207] Preferably, step S221 further includes the third operating head 59 removing the elastic strip 81 from the elastic sheet 8, moving the elastic strip 81 to the top of the correction platform 6 to correct the horizontal alignment of the elastic strip 81, and then moving the elastic strip 81 above the heating unit.
[0208] Furthermore, the arrangement of the support platform 2 and the second operating head 56 includes the following embodiments.
[0209] Option 1.1 The first arrangement of the support platform 2 and the second operating head 56 is as follows:
[0210] See Figure 3 and 18 A cutting station Q1 and a material handling station Q2 are arranged at intervals along the X-axis on the frame 1. An X-axis guide rail 57 is provided on the frame 1. A support table 2 is slidably mounted on the corresponding X-axis guide rail 57. At least one support table 2 is provided. When at least two support tables 2 are provided, the at least two support tables 2 are arranged at intervals along the Y-axis. Thus, at least two support tables 2 can move independently of each other, and their movement paths do not interfere with each other, so that the second operating head 56 can continuously cut the elastic sheet 8 carried by different support tables 2, thereby improving cutting efficiency and, consequently, strip application efficiency.
[0211] Specifically, the bottom of the support platform 2 is fixedly connected to a slide table, and is slidably mounted on the X-axis guide rail 57 via the slide table. (Hereinafter, the bottom of the support platform 2 is fixedly connected to a slide table, so that it is slidably mounted on the corresponding guide rail via the slide table.)
[0212] See 1-2 and Figure 4 Specifically, in order to enable the movement of the second operating head 56, the labeling device further includes at least one first Y-axis guide rail 54, and the number of second operating heads 56 is at least one.
[0213] When the number of the first Y-axis guide rail 54 and the second operating head 56 is one: the first Y-axis guide rail 54 is mounted on the frame 1 and located at the cutting station Q1. The second operating head 56 is slidably mounted on the first Y-axis guide rail 54 via the second slide table 55 and can move to any of the support tables 2 located at the cutting station Q1 to cut the elastic sheet 8 supported by the support table 2 into elastic strips 81.
[0214] Based on the above configuration, a second operating head 56 can perform cutting operations on any of the carrier tables 2 that have been moved to the cutting station Q1, thereby simplifying the structure and reducing the overall size of the machine. Furthermore, the second operating head 56 can continuously cut the elastic sheet 8 carried by different carrier tables 2 to improve cutting efficiency and thus improve strip application efficiency.
[0215] When the number of first Y-axis guide rails 54 and second operating heads 56 is at least two (including two or more): at least two first Y-axis guide rails 54 and X-axis guide rails 57 correspond one-to-one and are mounted on the frame 1 and located at the cutting station Q1.
[0216] At least two second operating heads 56 are slidably mounted on the first Y-axis guide rail 54 via the second slide table 55 to cut the elastic sheet 8 carried by the support table 2 located at the cutting station Q1.
[0217] The second operating head 56 is set to at least two and cuts independently. The at least two second operating heads 56 can simultaneously cut different elastic sheets 8. When one second operating head 56 is cutting and the third operating head 59 has completed the material picking and pasting operation, the other second operating head 56 can cut the elastic sheets 8 after all the cut elastic strips 81 have been taken out, so as to carry out simultaneous or continuous cutting operations. This can speed up the cutting efficiency, shorten the waiting time of the material picking head 512, shorten the waiting time between processes, and improve the strip pasting efficiency of the whole machine.
[0218] Option 1.2 The second arrangement of the support platform 2 and the second operating head 56 is as follows:
[0219] The cutting station Q1 includes a first cutting station and a second cutting station, with at least one first cutting station and the second cutting station located on both sides of the material handling station Q2 in the Y-axis direction.
[0220] A second Y-axis guide rail is provided on the frame 1, and at least two support platforms 2 are slidably mounted on the second Y-axis guide rail. The at least two support platforms 2 can move synchronously along the X-axis guide rail 57, so that the at least two support platforms 2 move to the first cutting station and the material picking station Q2 respectively, that is, at least one support platform 2 is located at the first cutting station and at least one support platform 2 is located at the material picking station Q2; or, the at least two support platforms 2 move to the second cutting station and the material picking station Q2 respectively, that is, at least one support platform 2 is located at the material picking station Q2 and at least one support platform 2 is located at the second cutting station.
[0221] At least two second operating heads 56 are provided, located at the first cutting station and the second cutting station respectively. At least one second operating head 56 is provided at the first cutting station, and at least one second operating head 56 is also provided at the second cutting station, to cut the elastic sheet 8 supported by the support platform 2 located at the first and second cutting stations. The at least two second operating heads 56 can perform simultaneous or continuous cutting operations, thereby accelerating cutting efficiency, shortening the waiting time for the material pick-up head 52 to pick up material, reducing inter-process waiting time, and improving the overall strip-applying efficiency of the machine.
[0222] It should be noted that the number of the first cutting station, the second cutting station, and the material handling station Q2 mentioned above is at least one.
[0223] Based on the above settings, the support platform 2 is always present at the first and second cutting stations, and the second operating head 56 can cut the elastic sheet 8 supported on the support platform 2 to achieve continuous cutting operations, thereby accelerating the cutting efficiency, shortening the waiting time of the material picking head 52 to pick up the material, thus shortening the waiting time between processes, and improving the overall strip application efficiency of the machine.
[0224] Specifically, this strip application device also includes at least two first XY-axis guide rails, which are mounted on the frame 1 and located at the first cutting station and the second cutting station, respectively. At least two second operating heads 56 are slidably mounted on the first XY-axis guide rails via second slides 55.
[0225] Thus, the second operating head 56 can move along the first XY axis guide rail on the X and Y axes relative to the support table 2 located at the first cutting station or the second cutting station, so as to cut the elastic sheet 8 supported by the support table 2.
[0226] Option 1.3 The third arrangement of the support platform 2 and the second operating head 56 is as follows:
[0227] The strip application device includes a rotary table and at least one second XY axis guide rail.
[0228] At least one material handling station Q2 and at least one cutting station Q1 are arranged circumferentially on the frame 1. A rotary table is rotatably mounted on the frame 1 about a vertical axis. At least two support platforms 2 are provided, arranged circumferentially on top of the rotary table. The rotary table is capable of rotating at least two support platforms 2 to the cutting station Q1 and the material handling station Q2, respectively.
[0229] When there is only one second XY axis guide rail and one second operating head 56, the second XY axis guide rail is mounted on the frame 1 and located at the cutting station Q1, and the second operating head 56 is slidably mounted on the second XY axis guide rail via the second slide table 55. Based on the above configuration, one second operating head 56 can perform cutting operations on any carrier table 2 that has been moved to the cutting station Q1, thereby simplifying the structure and reducing the overall size of the machine. Furthermore, the second operating head 56 can continuously cut the elastic sheet 8 carried by different carrier tables 2, thereby improving cutting efficiency and thus improving strip application efficiency.
[0230] When at least two second XY-axis guide rails and at least two second operating heads 56 are provided, the at least two second XY-axis guide rails are arranged circumferentially on the frame 1 and correspond one-to-one with the cutting station Q1. The at least two second operating heads 56 are slidably mounted on the second XY-axis guide rails through the second slide table 55. The at least two second operating heads 56 can perform cutting operations simultaneously or continuously, thereby accelerating the cutting efficiency, shortening the waiting time for the material pick-up head 52 to pick up the material, reducing the waiting time between processes, and improving the overall strip-applying efficiency of the machine.
[0231] The second operating head 56 can move along the first XY axis guide rail on the X and Y axes relative to the support table 2 located at the cutting station Q1, so as to cut the elastic sheet 8 supported by the support table 2.
[0232] Furthermore, based on the above-mentioned configurations of the support platform 2 and the second operating head 56, the arrangement of the third operating head 59 is as follows:
[0233] This strip application device also includes a third XY axis guide rail 57.
[0234] The third XY axis guide rail 57 is mounted on the frame 1 and located above the strip application table 3. The second slide table 55 is slidably mounted on the third XY axis guide rail 57. The third operating head 59 is mounted on the second slide table 55. The third operating head 59 can move along the third XY axis guide rail 57 via the second slide table 55 to above any of the bearing tables 2 located at the material picking station Q2, so as to pick up the elastic sheet 8 carried by any of the bearing tables 2. The third operating head 59 can also move to above the strip application table 3 to move the elastic strip 81 to be pasted onto the knife template 7.
[0235] Based on the aforementioned guide rails that support the movement of the support platform 2, the second operating head 56, and the third operating head 59, and the arrangement of the support platform 2 moving between the cutting station Q1 and the material handling station Q2, the cutting operation of the second operating head 56 and the material handling operation of the third operating head 59 can be made mechanically independent, thereby enabling parallel operation of multiple processes.
[0236] Preferably, all of the above guide rails are ball screw guide rails to ensure their rigidity and running accuracy.
[0237] Specifically, the second operating head 56 includes the cutting head 510 in Embodiment 3, and the cutting bracket 271 in the cutting head 510 is fixedly mounted on the second slide table 55. The third operating head 59 includes the material pick-and-place head 512 in Embodiment 3. The mounting base plate 5121 of the material pick-and-place head 512 is fixedly mounted on the third slide table 58.
[0238] Preferably, the third operating head 59 also includes the positioning head 511 in embodiment 3. The detection base plate 5111 of the positioning head 511 is fixedly mounted on the third slide table 58.
[0239] Based on the above settings, the labeling method of this labeling machine includes the following steps:
[0240] B1. Place the knife template 7 on the strip application table 3, and use the positioning head 511 to scan and detect the position and height of the knife template 7 relative to the strip application table 3.
[0241] B2. A batch of multiple elastic sheets 8 that need to be cut are placed one by one on multiple support tables 2 located at the cutting station Q1. After the cutting head 510 cuts the elastic sheet 8 on at least one support table 2 into multiple elastic strips 81 of the required shape and size, the support table 2 drives the cut elastic sheet 8 to move to the material picking station Q2.
[0242] B3. The cutting head 510 cuts the elastic sheet 8 carried by the other bearing tables 2 into multiple elastic strips 81 of the required shape and size. The bearing tables 2 move the cut elastic sheet 8 to the material handling station Q2. At the same time:
[0243] B31, the material handling head 512 takes the elastic strip 81 out of the elastic sheet 8 and moves the elastic strip 81 above the heating unit, and arranges the hot melt adhesive of the elastic strip 81 and the heating unit at intervals. The heating unit melts the hot melt adhesive at the bottom of the elastic strip 81.
[0244] B32. The material handling head 512 drives the elastic strip 81, which is made of hot melt adhesive at the bottom, to stick to the sticking position of the knife template 7 supported by the sticking table 3.
[0245] B33. Repeat steps B31-B32 until all the strip positions on the knife template 7 have been covered with elastic strips 81.
[0246] Preferably, step B31 further includes taking the elastic strip 81 out of the elastic sheet 8 by the pick-and-place head 512, and then moving the elastic strip 81 to the top of the correction platform 6 to correct the horizontal alignment of the elastic strip 81.
[0247] Preferably, the X-axis guide rail 21, the Y-axis guide rail 54, and the second XY-axis guide rail 57 are all ball screw guide rails to ensure the movement accuracy of the second operating head 56 and the third operating head 59.
[0248] Example 5
[0249] This embodiment is a further limitation based on embodiments 1-4.
[0250] The control system includes a programmable logic controller (PLC) and host computer software. The host computer software is used for graphics processing, path planning, and parameter setting, and sends the generated instructions to the PLC. The PLC, as the slave device, is responsible for receiving and executing these instructions, directly driving each actuator.
[0251] The drive motors for all the guide rails mentioned above, including the guide rails, XY-axis guide rails, X-axis guide rail 21, Y-axis guide rail 54, and second XY-axis guide rail 57, are all connected to the PLC. The drive motors, cylinders, or other drivers in the first operating head 53, second operating head 56, and third operating head 59 are all connected to the PLC. The heating element and temperature sensor of the heating unit are also connected to the PLC.
[0252] The host computer software can generate tool paths for the cutting head 510, positioning head 511, and pick-and-place head 512 based on the die pattern diagram of the die template 7, and send these paths to the PLC. The PLC first controls the positioning head 511 to scan and position the die template 7 using the tool path, thereby obtaining the position and height data of the die template 7 relative to the strip-applying table 3. Then, the PLC controls the first operating head 53, the second operating head 56, and the third operating head 59 accordingly based on the tool paths of the cutting head 510 and the pick-and-place head 512, as well as the position and height data of the die template 7 relative to the strip-applying table 3, to complete the cutting and pasting of the elastic strip. The PLC can also receive temperature data transmitted from the temperature sensor and control the heating temperature of the heating unit by adjusting the power of the heating element.
[0253] Temperature sensors are used to collect temperature data from the heating unit and transmit it to the PLC. The PLC is configured to process the temperature data and, based on the processing results, adjust the heating power of the heating element to control the temperature of the heating unit. The PLC stores multiple sets of matching parameter values for heating temperature, heating distance, and heating time, and can recall one set of parameters according to actual conditions.
[0254] When the heating plate 41 is movable, the PLC can control the slider to move the heating plate 41 on it based on the coordinates of the position A of the elastic strip removal on the support platform 2 and the coordinates of the current strip application position B on the strip application platform 3.
