Description

Technical Field

[0001] The present application relates to the field of printing technology, and in particular to a foil punching device, a embossing machine and a control method thereof. Background Art

[0002] Many products in daily life are designed with outer packaging, and the patterns and texts on the outer packaging are usually embossed by a stamping machine. At present, the stamping machine includes an upper platform and a lower platform arranged opposite to each other, and a stamping template is usually fixed on the bottom surface of the upper platform. When the sheet to be stamped is conveyed between the upper platform and the lower platform, the lower platform moves upward until the stamping template presses the stamping foil located between the upper platform and the lower platform onto the sheet, so that the pattern on the stamping template can be transferred to the surface of the sheet through the stamping foil.

[0003] Before stamping, the operator needs to use a special foil-piercing hook to push and pull the free end of the stamping foil through the gap between the upper platform and the lower platform multiple times, then pull the stamping foil to the top of the stamping machine, and finally fix the free end of the stamping foil on the reel. In the above manual foil-piercing process, not only does the operator need to change positions multiple times, which is labor-intensive and has low foil-piercing efficiency, but the gap between the upper platform and the lower platform is very narrow, resulting in a small operating space and easily obstructed vision, which greatly increases the difficulty of manual foil-piercing for the operator. In addition, the stamping foil is weak in strength, and if the operator uses improper force during manual foil-piercing, it is very easy to damage the stamping foil.

[0004] In order to reduce labor intensity and improve foil-piercing efficiency, some companies have adopted automatic foil-piercing devices. However, the existing automatic foil-piercing devices are not only complex in structure, but also easily get stuck and damaged due to the very narrow gap between the upper platform and the lower platform.

[0073] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0074] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0075] Combination Figures 1 to 5 As shown, an embodiment of the present application provides a foil penetration device 100, which includes a foil penetration rod 110, a first driving member 130, a controller, a plurality of transmission components, and a motion detector 140 corresponding to the transmission components. The plurality of transmission components are spaced apart from each other, and the first end and the second end of the foil penetration rod 110 are respectively fixed to different transmission components, so that the foil penetration rod 110 can move along a preset trajectory driven by the transmission component. The first driving member 130 is configured to drive the transmission component to drive the foil penetration rod 110 to move along the above-mentioned preset trajectory. The motion detector 140 is used to detect the motion parameters of the corresponding transmission component. The controller is electrically connected to the motion detector 140 and the first driving member 130, and the controller is configured to control the start and stop of the first driving member 130 according to the motion parameters detected by the motion detector 140. For example, Figure 1As shown, the foil penetration device 100 includes two sets of transmission components spaced apart from each other and arranged opposite to each other in the y direction. Figure 1 The foil penetration device 100 has only two transmission components, but in actual application, more than two transmission components can be provided according to specific conditions. Two motion detectors 140 can be provided, and are respectively provided corresponding to the two transmission components to respectively detect motion parameters of the two transmission components.

[0076] When threading the stamping foil, the operator can first fix the free end of the stamping foil on the foil threading rod 110, and then start the first driving member 130, so that the first driving member 130 drives the transmission assembly to drive the foil threading rod 110 to move along the preset track. As a result, the free end of the stamping foil moves synchronously with the foil threading rod 110, and moves from a preset starting position on the preset track to a stop position. For example, the preset track is a ring-shaped track, that is, a ring track with a gap. Figure 1 The position of the foil rod 110 drawn by the solid line is the starting position, and the position of the foil rod 110 drawn by the dotted line is the stopping position. When the stamping foil moves from the starting position of the preset track to the stopping position with the foil rod 110, the stamping foil surrounds and forms a cylindrical structure similar to a notch. In addition to the rim-shaped track, the preset track can also be a circular track, an arc track or a track of other shapes, which is not limited in this application. In the process of the first driving member 130 driving the transmission assembly to run, the motion detector 140 detects the motion parameters of the corresponding transmission assembly in real time and sends the detection results to the controller. If any group of transmission assemblies is blocked, the movement of the group of transmission assemblies will be blocked, and its motion parameters will change accordingly, such as the running speed slows down and the displacement becomes smaller. The controller compares the received motion parameters with the preset parameter range. If the motion parameters detected by any motion detector 140 deviate from the preset parameter range, it means that the transmission assembly may be blocked, and the controller can control the first driving member 130 to stop running. Of course, the controller can also compare the motion parameters detected by the two motion detectors 140 at the same time. If the difference between the two motion parameters deviates from the preset deviation range, it means that the corresponding two transmission components are not synchronized, and at least one set of transmission components is blocked. At this time, the controller can control the first drive member 130 to stop running. Therefore, whether one set of transmission components is blocked or multiple transmission components are blocked, it can be detected in time, ensuring that the controller can control the first drive member 130 to stop running in time.

[0077] It can be seen from the above that the implementation mode of the present application can not only realize automatic foil penetration, but also by setting a motion detector 140 corresponding to the transmission component and electrically connecting the controller to the motion detector 140 and the first drive member 130, it is possible to judge whether the transmission component is stuck based on the motion parameters detected by the motion detector 140, so that when any group of transmission components is stuck, the first drive member 130 can be controlled to stop running in time, thereby avoiding the asynchronous movement of multiple transmission components and causing damage to the transmission components and / or the foil penetration rod 110.

[0078] In some embodiments, the transmission assembly may include a plurality of transmission wheels and flexible cables 120, the plurality of transmission wheels are spaced apart along a preset track, the flexible cables 120 are wound around the plurality of transmission wheels to form an annular structure, the flexible cables 120 of different transmission assemblies have symmetrically arranged mounting positions, the first end and the second end of the foil-piercing rod 110 are respectively fixed at different mounting positions, and the first driving member 130 is connected to any one of the transmission wheels of one group of transmission assemblies. The flexible cable 120 may be an annular chain, and the transmission wheel is a sprocket engaged with the chain. The flexible cable 120 may also be an annular transmission belt, and the transmission wheel is a pulley matched with the transmission belt.

[0079] Considering that when the transmission component is blocked, the running speed of the part of the flexible cable 120 near the blocking position slows down or stops running, in order to make the transmission component have a certain buffer performance and further reduce the risk of damage to the flexible cable 120, Figure 1 , Figure 2 and Figure 4 As shown, the plurality of transmission wheels include a first transmission wheel 121, a second transmission wheel 122 and a third transmission wheel 123 which are sequentially spaced and distributed along a preset track. In other words, the flexible cable 120 is sequentially wound around the first transmission wheel 121, the second transmission wheel 122 and the third transmission wheel 123. The second transmission wheel 122 is slidably arranged on the same side of the first transmission wheel 121 and the third transmission wheel 123 along the first direction (x direction). The first driving member 130 is connected to the third transmission wheel 123 of one group of transmission assemblies. The transmission assembly also includes a second driving member, which is used to provide a driving force for sliding along the first direction (x direction) to the second transmission wheel 122. The second driving member may include, but is not limited to, a cylinder, a hydraulic cylinder or an elastic member 126 such as a spring, which is not limited in the present application. If the second driving member includes a pneumatic cylinder or a hydraulic cylinder, the driving force is actively applied to the second transmission wheel 122 by the second driving member; if the second driving member includes an elastic member 126 such as a spring, the driving force is passively applied to the second transmission wheel 122 by the second driving member itself deforming due to external force.

[0080] As an example, Figure 1 , Figure 5 and Figure 6As shown, the plurality of transmission wheels include a first transmission wheel 121, a second transmission wheel 122, a third transmission wheel 123, two fourth transmission wheels 124 and two fifth transmission wheels 125 which are sequentially spaced in a counterclockwise direction. The flexible cable 120 wound between the two fourth transmission wheels 124 is located between the upper platform 200 and the lower platform 300 of the stamping machine. The upper platform 200 is located between the flexible cable 120 wound between the two fourth transmission wheels 124 and the flexible cable 120 wound between the two fifth transmission wheels 125. The motion detector 140 is a speed detector arranged on the first transmission wheel 121. The second driving member may include an elastic member 126 arranged between the first transmission wheel 121 and the second transmission wheel 122. The elastic member 126 may be a spring. One end of the elastic member 126 is fixedly arranged, and the other end is connected to the second transmission wheel 122. Assuming that the flexible cable 120 is driven in a counterclockwise direction by the first driving member 130, if Figure 1 If the portion of the flexible cable 120 on the transmission side (rear side) wound around the two fourth transmission wheels 124 is blocked, the running speed of the downstream portion of the flexible cable 120 where the blockage occurs will slow down or stop running, thereby causing the rotation speed of the first transmission wheel 121 to slow down or stop, while the third transmission wheel 123 is transmission-connected to the first driving member 130, so that the third transmission wheel 123 continues to rotate counterclockwise at a normal speed under the drive of the first driving member 130. Since there is a speed difference between the third transmission wheel 123 and the first transmission wheel 121, and the second transmission wheel 122 is slidably disposed on the same side of the first transmission wheel 121 and the third transmission wheel 123 along the first direction, and the second transmission wheel 122 is connected to the elastic member 126, the existence of the speed difference causes the flexible cable 120 between the first transmission wheel 121 and the third transmission wheel 123 to apply a pulling force to the second transmission wheel 122, and the second transmission wheel 122 moves rightward along the first direction under the drive of the pulling force (see Figure 5 ). When the second transmission wheel 122 moves to the right, the elastic member 126 arranged on its right side will be compressed. The compressed length of the elastic member 126 can compensate for at least part of the displacement of the flexible cable 120 that is reduced after being blocked. During this process, the speed detector installed on the first transmission wheel 121 detects the rotation speed of the first transmission wheel 121 in real time and sends the detection result to the controller in real time. When the controller determines that the rotation speed deviates from the preset rotation speed range, it controls the first driving member 130 to stop running. As a result, the third transmission wheel 123 stops rotating, and the flexible cable 120 also stops running. Since, in the above process, the speed detector installed on another group of transmission components will also send the detection result to the controller in real time, the controller can also compare the results of the two speed detectors. If the difference between the two rotation speeds deviates from the preset deviation range, it means that the movements of the two flexible cables 120 are not synchronized. At this time, the controller can also control the first driving member 130 to stop running.

[0081] It should be noted that, in order to further improve the detection accuracy and avoid the detection error that may be caused by different detection positions, the motion detectors 140 may be symmetrically distributed on both sides of the foil-piercing rod 110 in the embodiment of the present application. For example, the foil-piercing device includes two motion detectors 140, and the two motion detectors 140 are symmetrically distributed relative to the foil-piercing rod 110. In other words, the two motion detectors 140 detect the same position of the corresponding transmission assembly respectively. In addition, the motion detector 140 in the embodiment of the present application can detect the motion parameters of the forward and reverse motion of the flexible cable 120 or one of the transmission wheels. As an example, the motion detector 140 may include a speed detector and / or a displacement detector, for example, the motion detector 140 may be an encoder or a proximity switch. As another example, the motion detector 140 may be arranged on any one of the transmission wheels except the second transmission wheel 122 and the third transmission wheel 123 to detect the motion parameters of the transmission wheel, or may be fixedly installed at any position adjacent to the flexible cable 120 to detect the motion parameters of the flexible cable 120. In view of the fact that the first transmission wheel 121 and the third transmission wheel 123 are respectively arranged on both sides of the second transmission wheel 122 along the preset trajectory, and the third transmission wheel 123 is transmission-connected to the first driving member 130, the second transmission wheel 122 can slide along the first direction, and compared with other transmission wheels, the first transmission wheel 121 is most affected when the flexible cable 120 is blocked, so in order to further improve the detection accuracy and response speed, the motion detector 140 in the embodiment of the present application can be arranged on the first transmission wheel 121. In addition, in order to be able to remind the operator in time, the foil penetration device 100 can also include an alarm device electrically connected to the controller, and the controller can control the alarm device to start and stop according to the motion parameters detected by the motion detector 140. Among them, the alarm device can be, but is not limited to, a warning light, a buzzer, etc.

[0082] In some embodiments, Figure 2As shown, the first driving member 130 may include a driving rod 131 and a driving motor 132, the two ends of the driving rod 131 respectively penetrate the third transmission wheel 123 of the corresponding transmission assembly and are fixedly connected to the third transmission wheel 123, and the driving motor 132 is connected to the end of the driving rod 131 in a transmission manner. Since the position where the flexible cable 120 is stuck is usually located between the upper platform 200 and the lower platform 300, in other words, compared with other positions, the probability of the flexible cable 120 being stuck between the two fourth transmission wheels 124 is very high, and the third transmission wheel 123 is relatively close to the fourth transmission wheel 124, fixing the driving rod 131 on the third transmission wheel 123 can not only improve the response speed, but also make the protection range more comprehensive. In addition, it should be noted that the output shaft of the driving motor 132 can be directly fixedly connected to any end of the driving rod 131, or it can be indirectly connected to any end of the driving rod 131 through an intermediate transmission assembly. The intermediate transmission assembly may include a driving wheel 133, a driven wheel 134 and an intermediate flexible cable 135, wherein the driving wheel 133 is fixed to the output shaft of the driving motor 132, the driven wheel 134 is fixed to one end of the driving rod 131, and the driving wheel 133 is connected to the driven wheel 134 through the intermediate flexible cable 135. The intermediate flexible cable 135 may be an annular chain, and the driving wheel 133 and the driven wheel 134 may be sprockets meshed with the chain. The intermediate flexible cable 135 may also be an annular transmission belt, and the driving wheel 133 and the driven wheel 134 may be pulleys matched with the transmission belt. Thus, after the controller controls the driving motor 132 to start, the output shaft of the driving motor 132 drives the driving wheel 133 to rotate synchronously, and the driving wheel 133 drives the driven wheel 134 to rotate synchronously through the intermediate flexible cable 135, and the driven wheel 134 is fixed to the end of the driving rod 131, so that the driving rod 131 will rotate accordingly, and then drive the third transmission wheel 123 fixed to the driving rod 131 to rotate, and the third transmission wheel 123 can drive the flexible cable 120 to move, and then drive other transmission wheels to rotate synchronously through the flexible cable 120. It should be noted that the first driving member 130 in the embodiment of the present application is not limited to the above-mentioned structural form, and the first driving member 130 can also adopt other structural forms, for example, the first driving member 130 can include a driving motor 132, a driving rod 131, a driving gear and a driven gear, the driving gear is fixed to the output shaft of the driving motor 132, and the driven gear is fixed to one end of the driving rod 131, and the driving gear and the driven gear are meshed with each other.

[0083] like Figure 1 , Figure 3 and Figure 5As shown, in the embodiment of the present application, the plurality of transmission wheels also include two fourth transmission wheels 124 adjacent and spaced along a preset track, and the transmission assembly also includes a lifting drive 160 corresponding to the fourth transmission wheel 124 and electrically connected to the controller, and the lifting drive 160 is connected to the corresponding fourth transmission wheel 124, and is used to drive the corresponding fourth transmission wheel 124 to switch between multiple preset positions along the second direction (z), and the second direction (z) intersects with the extension direction of the flexible cable 120 wound between the two fourth transmission wheels 124. Among them, the first direction can intersect with the second direction. For example, the first direction is perpendicular to the second direction. If the second drive member includes a cylinder or a hydraulic cylinder, then the second drive member is linked with the lifting drive member 160. In other words, when the lifting drive member 160 drives the fourth transmission wheel 124 to move along the second direction, the second drive member will drive the second transmission wheel 122 to slide along the first direction to tension the flexible cable 120 or prevent the flexible cable 120 from being broken. If the second driving member includes an elastic member 126 , as the lifting driving member 160 drives the fourth transmission wheel 124 to move, the elastic member 126 will automatically deform due to the external force applied by the flexible cable 120 , thereby passively applying a driving force to slide along the first direction to the second transmission wheel 122 .

[0084] Among them, the number of preset positions can be determined according to the size of the internal space of the stamping machine, and the number of preset positions can be two, three or more than three, which is not limited in this application. Taking the case that the lower platform 300 can reciprocate up and down along the z direction relative to the upper platform 200 as an example, if the space of the stamping machine along the y direction is very small, then due to the space limitation in the y direction and in order to avoid the tooth row for clamping the sheet, the flexible rope 120 wound between the two fourth transmission wheels 124 is usually located directly below the upper platform 200. In other words, the flexible rope wound between the two fourth transmission wheels 124 is located on the reciprocating stroke of the lower platform 300. In this case, if the space between the upper platform 200 and the lower platform 300 along the z direction is relatively large, then in order to avoid the lower platform 300 during stamping, the lifting drive 160 can drive the fourth transmission wheel 124 to switch between the hidden position and the foil penetration position along the second direction (z), and the foil penetration position is located on the side of the hidden position away from the upper platform 200. When the fourth transmission wheel 124 is in the hidden position, the stamping machine can perform the stamping process, and when the fourth transmission wheel 124 is in the foil penetration position, the foil penetration process and the process of replacing the stamping template can be respectively performed. On the contrary, in the above case, if the space between the upper platform 200 and the lower platform 300 along the z direction is small, then in order to avoid the lower platform 300 during stamping and to prevent the foil penetration rod 110 from being too close to the lower platform 300 to affect the foil penetration, the lifting drive member 160 can drive the fourth transmission wheel 124 to switch between the hidden position, the foil penetration position and the avoidance position along the second direction (z), and the foil penetration position and the avoidance position are both located on the side of the hidden position away from the upper platform 200. When the fourth transmission wheel 124 is in the hidden position, the stamping machine can perform the stamping process, and when the fourth transmission wheel 124 is in the foil penetration position, the foil penetration process can be performed, and when the fourth transmission wheel 124 is in the avoidance position, the process of replacing the stamping template can be performed.

[0085] If the space of the stamping machine along the y direction is relatively large, then the flexible cable 120 wound between the two fourth transmission wheels 124 can be located obliquely below the upper platform 200. In other words, on the plane perpendicular to the z direction, the projection of the flexible cable wound between the two fourth transmission wheels 124 is located outside the projection of the upper platform 200, that is, the projections of the two do not overlap. In this case, if the space between the upper platform 200 and the lower platform 300 along the z direction is small, then in order to avoid the foil penetration rod 110 being too close to the lower platform 300 and affecting the foil penetration, the lifting drive 160 can drive the fourth transmission wheel 124 to switch between the foil penetration position and the avoidance position along the second direction (z), and the avoidance position is located on the side of the foil penetration position away from the upper platform 200. When the fourth transmission wheel 124 is located at the foil insertion position, the stamping machine performs the foil insertion process and the stamping process respectively. When the fourth transmission wheel 124 is located at the avoidance position, the stamping machine performs the process of replacing the stamping template. On the contrary, in this case, if the space between the upper platform 200 and the lower platform 300 along the z direction is relatively large, then the lifting drive member 160 may not be provided. In other words, the fourth transmission wheel 124 may be fixedly provided at the foil insertion position so that the flexible cable 120 wound between the two fourth transmission wheels 124 is suspended between the upper platform 200 and the lower platform 300.

[0086] The following is an example in which the lifting drive member 160 can drive the fourth transmission wheel 124 to switch between the hidden position, the foil penetration position and the avoidance position along the second direction (z) to illustrate the working principle of the foil penetration device in the embodiment of the present application:

[0087] Since the space of the stamping machine along the y direction is very small in this case, and the space between the upper platform 200 and the lower platform 300 along the z direction is also relatively small, when the foil threading device 100 is applied to the stamping machine, the flexible cable 120 wound between the two fourth transmission wheels 124 of the transmission assembly is located between the upper platform 200 and the lower platform 300 of the stamping machine, and is located directly below the upper platform 200, that is, on the reciprocating travel of the lower platform 300.

[0088] Thus, when threading the stamping foil, the four lifting drive members 160 can be controlled by the controller to drive the corresponding fourth transmission wheel 124 to move to the foil threading position. At this time, the flexible rope 120 wound between the two fourth transmission wheels 124 of each group of transmission components is suspended between the upper platform 200 and the lower platform 300. Then, the operator can first fix the free end of the stamping foil on the foil threading rod 110, and control the first drive member 130 to drive the third transmission wheel 123 to rotate through the controller. Assuming that the third transmission wheel 123 rotates counterclockwise, the third transmission wheel 123 will drive the flexible rope 120 to move in the counterclockwise direction, and at the same time, the flexible rope 120 will drive other transmission wheels to rotate synchronously counterclockwise. Thus, the free end of the stamping foil will move from the starting position of the preset track to the stop position of the preset track in the counterclockwise direction with the foil threading rod 110. In this process, the free end of the stamping foil passes through the gap between the upper platform 200 and the lower platform 300, so that part of the stamping foil is located between the upper platform 200 and the lower platform 300. like Figure 4 As shown, in order to facilitate the control of the start or stop of the foil-penetrating rod 110, a starting point detector 151 and an end point detector 152 can be respectively installed at a preset starting position and a preset end point distributed at intervals along the preset track. The position adjacent to the starting point detector 151 on the preset track is the starting position of the foil-penetrating rod 110, and the position adjacent to the end point detector 152 is the stopping position of the foil-penetrating rod 110. The starting point detector 151 and the end point detector 152 are respectively electrically connected to the controller for detecting the foil-penetrating rod 110. The preset starting position and the preset end point can be adjacent to each other along the preset track. For example, Figure 4 As shown, the preset starting position and the preset end position can be respectively located at both sides of the first transmission wheel 121, specifically, the preset starting position can be set on the side of the first transmission wheel 121 away from the second transmission wheel 122, and the preset end position can be set on the side of the first transmission wheel 121 close to the second transmission wheel 122, the starting point detector 151 is fixed at the preset starting position, and the end point detector 152 is fixed at the preset end point. As an example, the starting point detector 151 and the end point detector 152 can be, but not limited to, a proximity switch or a photoelectric switch. Thus, when the foil-piercing rod 110 is in the starting position, the starting point detector 151 set near the starting position will be triggered, in other words, at this time, the starting point detector 151 detects the foil-piercing rod 110, and the starting point detector 151 sends the detection result to the controller, and the controller can control the first drive member 130 to start, so as to drive the foil-piercing rod 110 to move along the preset track. When the foil-piercing rod 110 reaches the stop position, the end point detector 152 set near the stop position will be triggered, and the end point detector 152 sends the detection result to the controller, and the controller can control the first drive member 130 to stop running. At this point, the foil-piercing rod 110 has completed the foil-piercing process.

[0089] like Figure 5As shown, during stamping, the controller can be used to control the four lifting drive members 160 to drive the corresponding fourth transmission wheel 124 to move upward, so that the fourth transmission wheel 124 is switched from the foil-piercing position to the hidden position. Due to the presence of the elastic member 126, the second transmission wheel 122 will move to the left along the first direction under the drive of the elastic member 126 during this process to tighten the flexible cable 120. The side of the upper platform 200 facing the lower platform 300 can be pre-installed with an embossing template (hot stamping plate), and the conveying device 500 of the stamping machine conveys the sheet to be stamped to the lower platform 300 through the teeth. At this time, the stamping foil and the sheet are located between the stamping template and the lower platform 300, and the stamping foil is located on the side of the sheet facing the stamping template. Then, the lower platform 300 can be controlled to move upward until the stamping template presses the stamping foil on the sheet, so that the pattern on the stamping template is transferred to the surface of the sheet through the stamping foil. Thus, the stamping process of one of the sheets is completed. During the entire stamping process, the first driving member 130 of the foil punching device 100 stops running. In other words, the foil punching rod 110 and the flexible cable 120 are in a stationary state during the stamping process.

[0090] When replacing the stamping template, the lower platform 300 can be controlled to move downward first, and then the four lifting drive members 160 can be controlled by the controller to drive the corresponding fourth transmission wheel 124 to move downward synchronously, so that the fourth transmission wheel 124 is switched from the hidden position to the avoidance position, and the avoidance position is located on the side of the foil penetration position away from the hidden position. In this process, the second transmission wheel 122 will move rightward along the first direction under the pull of the flexible cable 120 to compensate for the displacement difference caused by the downward movement of the fourth transmission wheel 124. When the fourth transmission wheel 124 moves to the avoidance position, the gap between the lower platform 300 and the upper platform 200 reaches the maximum, and the operator can use this gap to replace the stamping template.

[0091] It should be noted that, in the embodiment of the present application, the first driving member 130 can not only drive the flexible cable 120 to move in the counterclockwise direction, but also can drive the flexible cable 120 to move in the clockwise direction, which is not limited in the present application. Figure 3As shown, the lifting drive member 160 may include a slider 163, a fixedly arranged slide rail 162 and a cylinder 161, the slide rail 162 extends along the second direction (z direction), the slider 163 is slidably arranged in the slide rail 162, the piston rod of the cylinder 161 is connected to the slider 163 to drive the slider 163 to move up and down along the slide rail 162, and the rotating shaft of the fourth transmission wheel 124 is rotatably connected to the slider 163. Therefore, when the cylinder 161 drives the slider 163 to move up or down along the slide rail 162, the fourth transmission wheel 124 will also move synchronously therewith, thereby realizing the switching of the fourth transmission wheel 124 between multiple positions. Of course, the lifting drive member 160 is not limited to the above-mentioned structural form, and the lifting drive member 160 can also adopt other structural forms. For example, the lifting drive member 160 can include a driving motor 132, a lead screw and a nut. The axial direction of the lead screw is parallel to the second direction (z direction), the nut is screwed on the lead screw, the driving motor 132 is connected to the lead screw to drive the lead screw to rotate, and the rotating shaft of the fourth transmission wheel 124 is rotatably connected to the nut. Therefore, when the driving motor 132 drives the lead screw to rotate, the nut will drive the fourth transmission wheel 124 to move upward or downward along the lead screw.

[0092] like Figure 6 As shown, the embodiment of the present application further provides a stamping machine, which includes an upper platform 200, a lower platform 300 and the above-mentioned foil penetration device 100, the lower platform 300 is arranged opposite to the upper platform 200, the distance between the upper platform 200 and the lower platform 300 is adjustable, and part of the transmission assembly is located between the upper platform 200 and the lower platform 300, so that the preset trajectory passes through the gap between the upper platform 200 and the lower platform 300. In order to adjust the distance between the upper platform 200 and the lower platform 300, in the embodiment of the present application, the lower platform 300 can move up and down relative to the upper platform 200, the upper platform 200 can move up and down relative to the lower platform 300, or both the upper platform 200 and the lower platform 300 can move up and down.

[0093] like Figure 1 and Figure 5As shown, the foil penetration device 100 includes a foil penetration rod 110, a first drive member 130, two groups of transmission components and motion detectors corresponding to the transmission components, the two groups of transmission components are spaced apart and arranged relative to each other, the first end and the second end of the foil penetration rod 100 are respectively fixed to the two groups of transmission components, and the motion detector 140 and the first drive member 130 are respectively electrically connected to the controller. Wherein, the transmission assembly includes a first transmission wheel 121, a second transmission wheel 122, a third transmission wheel 123 and two fourth transmission wheels 124, which are sequentially spaced along a preset track, and a flexible rope 120 wound around the above-mentioned transmission wheels, a second drive member corresponding to the second transmission wheel 122, and a lifting drive member 160 corresponding to the fourth transmission wheel 124. The second transmission wheel 122 is slidably arranged on the same side of the first transmission wheel 121 and the third transmission wheel 123 along the first direction (x direction), and the second drive member is used to provide a driving force for sliding along the first direction (x direction) to the second transmission wheel 122. The second driving member may be an elastic member 126 disposed between the first transmission wheel 121 and the second transmission wheel 122, one end of the elastic member 126 being fixedly disposed, and the other end being connected to the second transmission wheel 122. The first driving member 130 is transmission-connected to the third transmission wheel 123 of any group of transmission components to drive the third transmission wheel 123 to rotate. The flexible cable 120 wound between the two fourth transmission wheels 124 is located between the upper platform 200 and the lower platform 300, and the lifting driving member 160 is connected to the fourth transmission wheel 124 to drive the fourth transmission wheel 124 to switch between a plurality of preset positions along the second direction (z direction). The number of preset positions may be determined according to the size of the internal space of the stamping machine, and the number of preset positions may be two, three or more than three, which is not limited in the present application.

[0094] In order to facilitate the replacement of the imprint template, a slidable frame 210 is provided on one side of the upper platform 200 facing the lower platform 300 along the third direction (y direction), and the frame 210 includes a receiving groove and a template installation area for installing the imprint template on one side facing the lower platform 300, and the third direction intersects with the second direction. For example, the first direction, the second direction and the third direction are perpendicular to each other.

[0095] In addition, in order to facilitate the retracting and unwinding of the stamping foil, the stamping machine further includes an unwinding device 400 and a rewinding device (not shown), the unwinding device 400 unwinds the stamping foil to the foil-piercing device 100, and the rewinding device rewinds the stamping foil output by the foil-piercing device 100. In order to save space and make the layout of the entire stamping machine more compact, the unwinding device 400 can be set near the starting position of the foil-piercing rod 110, that is, near the preset starting position, and the rewinding device can be set near the stop position of the foil-piercing rod 110, that is, near the preset end position. Among them, the lower platform 300, the unwinding device 400 and the rewinding device can all be electrically connected to the controller of the foil-piercing device 100, and are uniformly controlled by the controller of the foil-piercing device 100. The lower platform 300, the unwinding device 400 and the rewinding device can also be electrically connected to their own independent controllers, and these controllers and the controller of the foil-piercing device 100 are then electrically connected to the master controller, and the master controller is uniformly controlled through the above-mentioned controllers.

[0096] It should be noted that in the present application embodiment, the unwinding device 400 and the reeling device may include a reel and a reel motor, the reel is used to wind the stamping foil, and the reel motor is used to drive the reel to rotate. In addition, one or more unwinding devices 400 and reeling devices can be set according to actual needs, and the unwinding device 400 and the reeling device are correspondingly set. If the number of unwinding devices 400 is multiple, multiple unwinding devices 400 can be arranged in sequence along the axial direction of the foil rod 110. When the stamping foil is inserted, the free end of the stamping foil wound around each unwinding device 400 can be fixed on the foil rod 110 in sequence along the axial direction of the foil rod 110. When the stamping foil is inserted, that is, when the first driving member 130 is started, multiple unwinding devices 400 should be operated synchronously. And in the stamping process, when the lower platform 300 moves downward to replace the sheet material, multiple unwinding devices 400 can be operated at different speeds according to the size of the stamping pattern corresponding to each other.

[0097] In addition, the speed at which the unwinding device 400 releases the stamping foil may also affect the operation of the transmission assembly. For example, if the unwinding device 400 releases the stamping foil too quickly during the process of threading the stamping foil, the stamping foil between the foil threading rod 110 and the unwinding device 400 may not be fully tensioned, causing part of the stamping foil to bulge, so that when the stamping foil passes between the upper platform 200 and the lower platform 300, the bulging part of the stamping foil is easily scratched against other structures such as the frame 210, which not only damages the stamping foil, but also may cause the moving speeds of the two flexible cables 120 to be inconsistent, resulting in stress between the flexible cables 120 and the foil threading rod 110, thereby damaging the flexible cables 120 and / or the foil threading rod 110. On the contrary, if the speed at which the unwinding device 400 releases the stamping foil is too slow, the stamping foil between the foil-piercing rod 110 and the unwinding device 400 may be over-tightened, causing the stamping foil to apply a pulling force to the foil-piercing rod 110, and the direction of the pulling force is opposite to the moving direction of the foil-piercing rod 110, which can easily cause the two flexible cables 120 to move out of sync, thereby damaging the flexible cables 120 and / or the foil-piercing rod 110. Based on this, in order to further reduce the risk of damage to the flexible cables 120 and the foil-piercing rod 110, when the stamping foil is threaded, that is, when the first driving member 130 is started, in the embodiment of the present application, the first driving member 130 and the unwinding device 400 operate synchronously, so that the moving speed of the foil-piercing rod 110 is the same as the speed at which the unwinding device 400 releases the stamping foil. In other words, the moving distance of the foil-piercing rod 110 along the flexible cable 120 is equal to the length of the stamping foil released by the unwinding device 400.

[0098] In some embodiments, the stamping machine may further include a feeding device, a conveying device 500 and a discharging device, wherein the feeding device is located upstream of the conveying device 500, and the discharging device is located downstream of the conveying device 500. The conveying device 500 includes a chain and a tooth bar fixed on the chain, and part of the chain is located between the upper platform 200 and the lower platform 300. A plurality of sheets to be stamped are stacked in the feeding device, and when the conveying device 500 is in operation, the tooth bar moves along the chain to clamp the stacked sheets in the feeding device one by one between the upper platform 200 and the lower platform 300 for stamping, and the stamped sheets are then clamped by the tooth bar to the discharging device, and the stamped sheets are stacked and temporarily stored in the discharging device. It should be noted that the feeding device, the conveying device 500 and the discharging device in the embodiments of the present application may directly adopt the existing corresponding devices, and the specific structure of the above-mentioned devices will not be described in detail in this application.

[0099] As described above, the lifting drive member 160 can drive the corresponding fourth transmission wheel 124 to switch between multiple preset positions along the second direction (z). The following takes the multiple preset positions including the hidden position, the foil insertion position and the avoidance position spaced apart along the second direction (z) as an example to illustrate the working principle of the stamping machine in the embodiment of the present application:

[0100] When threading the stamping foil, the controller can first control the four lifting drive members 160 to drive the corresponding fourth transmission wheel 124 to move to the foil threading position. At this time, the flexible rope 120 wound between the two fourth transmission wheels 124 of each transmission assembly is suspended between the upper platform 200 and the lower platform 300. Next, the operator can first fix the free end of the stamping foil wound on the unwinding device 400 on the foil threading rod 110; then, the driving motor 132 and the unwinding device 400 are controlled to run synchronously so that the moving speed of the foil threading rod 110 is the same as the speed at which the unwinding device 400 releases the stamping foil. In other words, the moving distance of the foil threading rod 110 along the flexible rope 120 is equal to the length of the stamping foil released by the unwinding device 400. In this process, the free end of the stamping foil moves along the flexible rope 120 toward the stop position along the foil threading rod 110 through the gap between the upper platform 200 and the lower platform 300. When the foil-piercing rod 110 reaches the stop position, the end point detector 152 is triggered, and the end point detector 152 sends the detection result to the controller, and the controller can control the drive motor 132 and the unwinding device 400 to stop running. At this time, the foil-piercing rod 110 has completed the foil-piercing process, and the operator can remove the free end of the stamping foil from the foil-piercing rod 110 and fix it on the winding device.

[0101] During stamping, the foil insertion device 100 can first control the four lifting driving members 160 through the controller to drive the corresponding fourth transmission wheel 124 to move upward, so that the fourth transmission wheel 124 is switched from the foil insertion position to the hidden position. Due to the presence of the elastic member 126, the second transmission wheel 122 will move leftward along the first direction under the drive of the elastic member 126 during this process to tension the flexible cable 120. When the fourth transmission wheel 124 is in the hidden position, the flexible cable 120 wound between the two fourth transmission wheels 124 of the transmission assembly is just embedded in the receiving groove of the frame 210, the stamping template installed in the template installation area is located between the two flexible cables 120, and the stamping foil located between the upper platform 200 and the lower platform 300 covers the surface of the stamping template facing the lower platform 300. At this time, there is a relatively large gap between the upper platform 200 and the lower platform 300, and the teeth of the conveying device 500 can clamp the sheet to be stamped to the lower platform 300. Next, the lower platform 300 can be controlled to move upward until the stamping template presses the stamping foil on the sheet material, so as to transfer the pattern on the stamping template to the surface of the sheet material through the stamping foil. Thus, the stamping process of one of the sheets is completed, and the foil rod 110 and the flexible rope 120 are in a stationary state during the entire stamping process. After that, the next sheet material can be stamped. Specifically, the lower platform 300 can be controlled to move downward first, so that the teeth of the conveying device 500 clamp the stamped sheet material to the discharging device, and clamp the new sheet material to be stamped in the feeding device to the lower platform 300. In this process, the unwinding device 400 and the winding device can be controlled to run synchronously at a specified speed according to the size of the stamping pattern, so as to drive the stamping foil to move along the flexible rope 120 toward the winding device, so that the used part of the stamping foil is wound around the winding device, and the unused part moves between the upper platform 200 and the lower platform 300. Then, after the conveying device 500 conveys the new sheet to be stamped to the lower platform 300, the lower platform 300 is controlled to move upward again until the stamping template presses the stamping foil on the sheet. Thus, the conveying device 500 loads and unloads the sheet, and the upper platform 300 reciprocates up and down. Through the cooperation of the conveying device 500 and the lower platform 300, the sheets stored in the feeding device can be stamped one by one.

[0102] When replacing the embossing template, the lower platform 300 can be controlled to move downward first, and at the same time, the controller controls the four lifting drive members 160 to drive the corresponding fourth transmission wheel 124 to move downward synchronously, so that the fourth transmission wheel 124 switches from the hidden position to the avoidance position, and the avoidance position is located below the foil penetration position. In this process, the second transmission wheel 122 moves to the right along the first direction under the pull of the flexible cable 120 to compensate for the displacement difference caused by the downward movement of the fourth transmission wheel 124. When the fourth transmission wheel 124 moves to the avoidance position, the gap between the lower platform 300 and the upper platform 200 reaches the maximum, and the operator pulls out the frame 210 from the bottom of the upper platform 200 along the third direction (y direction) to replace the embossing template.

[0103] like Figure 7 As shown, the embodiment of the present application also provides a control method of an embossing machine, Figure 7 A flow chart of an embodiment of a control method for an embossing machine according to the present application is shown. The control method for an embossing machine provided in the embodiment of the present application is generally executed by an electronic device such as a controller. The control method 1000 may include the following steps:

[0104] S110, increasing the distance between the upper platform 200 and the lower platform 300 to a first distance; for example, controlling the lower platform 300 to move downward until the distance between the upper platform 200 and the lower platform 300 reaches the first distance, so as to facilitate subsequent threading of the stamping foil.

[0105] S120, start the first driving member 130; after the first driving member 130 is started, it will drive the foil-piercing rod 110 to move along the flexible rope 120, and the free end of the stamping foil will move along the flexible rope 120 from the starting position through the gap between the upper platform 200 and the lower platform 300 to the stop position.

[0106] S130. During the execution of step S120, if the motion parameter detected by any one of the motion detectors 140 deviates from the preset parameter range and / or the difference in the motion parameters detected by the two motion detectors 140 deviates from the preset deviation range, it means that the two flexible cables 120 move asynchronously and stress is generated between the foil-piercing rod 110 and the flexible cables 120. At this time, the first driving member 130 can be controlled to stop running.

[0107] In some embodiments, in order to facilitate the control of the start or stop of the foil-penetrating rod 110, a starting point detector 151 and an end point detector 152 can be respectively installed at a preset starting position and a preset end point distributed at intervals along a preset track, the position adjacent to the starting point detector 151 on the preset track is the starting position of the foil-penetrating rod 110, and the position adjacent to the end point detector 152 is the stop position of the foil-penetrating rod 110, and the starting point detector 151 and the end point detector 152 are respectively electrically connected to the controller for detecting the foil-penetrating rod 110. Wherein, step S120 may include: in response to the starting point detector 151 detecting the foil-penetrating rod 110, controlling the first driving member 130 to start. In addition, the control method may also include: in response to the end point detector 152 detecting the foil-penetrating rod 110, controlling the first driving member 130 to stop running. Of course, when the foil-penetrating rod 110 is located at the starting position (stop position), in addition to automatically controlling the start (stop) of the first driving member 130 by means of the starting point detector 151 (end point detector 152), the operator can also manually control the start or stop of the first driving member 130 through the controller.

[0108] It should be noted that if the space of the stamping machine along the y direction is relatively large, and the space between the upper platform 200 and the lower platform 300 along the z direction is relatively large, then the fourth transmission wheel 124 can be fixedly arranged between the upper platform 200 and the lower platform 300. In other words, the position of the fourth transmission wheel 124 remains unchanged during the foil insertion process, the stamping process and the template replacement process, and there is no need to adjust the position of the fourth transmission wheel 124. If the space of the stamping machine along the y direction and / or the z direction is small, then the position of the fourth transmission wheel 124 needs to be adjusted during the operation of the stamping machine. For example, if the space of the stamping machine along the y direction is very small, then due to the space limitation in the y direction and in order to avoid the teeth row for clamping the sheet, the flexible cable 120 wound between the two fourth transmission wheels 124 is usually located directly below the upper platform 200. In other words, the flexible cable wound between the two fourth transmission wheels 124 is located on the reciprocating travel of the lower platform 300. In this case, if the space between the upper platform 200 and the lower platform 300 along the z direction is relatively large, then in order to avoid the lower platform 300 during stamping, the lifting drive 160 can drive the fourth transmission wheel 124 to switch between the hidden position and the foil insertion position along the second direction (z), and the foil insertion position is located on the side of the hidden position away from the upper platform 200. The stamping process can be performed when the fourth transmission wheel 124 is in the hidden position, and the foil insertion process and the process of replacing the stamping template can be performed when the fourth transmission wheel 124 is in the foil insertion position. Conversely, in the above case, if the space between the upper platform 200 and the lower platform 300 along the z direction is small, then in order to avoid the lower platform 300 during stamping and avoid the foil insertion rod 110 being too close to the lower platform 300 to affect the foil insertion, the lifting drive 160 can drive the fourth transmission wheel 124 to switch between the hidden position, the foil insertion position and the avoidance position along the second direction (z), and the foil insertion position and the avoidance position are both located on the side of the hidden position away from the upper platform 200. When the fourth transmission wheel 124 is in the hidden position, the stamping machine can perform the stamping process, when the fourth transmission wheel 124 is in the foil penetration position, the foil penetration process can be performed, and when the fourth transmission wheel 124 is in the avoidance position, the process of replacing the stamping template can be performed. If the space of the stamping machine along the y direction is relatively large, then the flexible rope 120 wound between the two fourth transmission wheels 124 can be located obliquely below the upper platform 200. In other words, on the plane perpendicular to the z direction, the projection of the flexible rope wound between the two fourth transmission wheels 124 is located outside the projection of the upper platform 200, that is, the projections of the two do not overlap. In this case, if the space between the upper platform 200 and the lower platform 300 along the z direction is small, then in order to avoid the foil penetration rod 110 from being too close to the lower platform 300 and affecting the foil penetration, the lifting drive 160 can drive the fourth transmission wheel 124 to switch between the foil penetration position and the avoidance position along the second direction (z), and the avoidance position is located on the side of the foil penetration position away from the upper platform 200.When the fourth transmission wheel 124 is located at the foil insertion position, the stamping machine performs the foil insertion process and the stamping process respectively. When the fourth transmission wheel 124 is located at the avoidance position, the stamping machine performs the process of replacing the stamping template.

[0109] Based on this, if the space of the stamping machine along the y direction and / or the z direction is small, then during the foil insertion process, that is, after executing step S110 and before executing step S120, the control method may further include: controlling the lifting drive 160 to drive the fourth transmission wheel 124 to switch to the foil insertion position, so that the flexible cable 120 wound between the two fourth transmission wheels 124 is suspended between the frame 210 and the lower platform 300.

[0110] If the space of the stamping machine along the y direction is small, then when performing the stamping process, the control method may further include: in response to the foil-piercing rod 110 at least passing through the gap between the upper platform 200 and the lower platform 300, controlling the lifting drive member 160 to drive the fourth transmission wheel 124 to switch to the hidden position, so that the flexible rope 120 wound between the two fourth transmission wheels 124 is embedded in the receiving groove of the frame 210. Reduce the spacing between the upper platform 200 and the lower platform 300 until the stamping foil is stamped on the sheet between the frame 210 and the lower platform 300. Thus, the stamping process of one of the sheets is completed. In the process of the fourth transmission wheel 124 moving to the hidden position, the second transmission wheel 122 will move to the left along the first direction under the drive of the elastic member 126 to tension the flexible rope 120. When the fourth transmission wheel 124 is in the hidden position, the flexible cable 120 wound between the two fourth transmission wheels 124 of the transmission assembly is just embedded in the receiving groove of the frame 210, and the stamping template installed in the template installation area is located between the two flexible cables 120. In addition, the control method may also include: in response to the foil-piercing rod 110 moving to the stop position of the preset track, controlling the first driving member 130 to stop running. At this time, the foil-piercing rod 110 has completed the foil-piercing process, and the operator can remove the free end of the stamping foil from the foil-piercing rod 110 and fix it on the winding device.

[0111] If the space of the stamping machine along the y direction and the z direction is small, then in the process of replacing the stamping template, the control method may further include: increasing the distance between the upper platform 200 and the lower platform 300 to the second distance; controlling the lifting drive 160 to drive the fourth transmission wheel 124 to switch to the avoidance position, so that the flexible rope 120 wound between the two fourth transmission wheels 124 is close to the lower platform 300. For example, the flexible rope 120 wound between the two fourth transmission wheels 124 can be attached to the lower platform 300. At this time, the operator can pull out the frame 210 from the bottom of the upper platform 200 along the third direction to replace the stamping template.

[0112] The above specific implementations do not constitute a limitation on the protection scope of the present disclosure. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
