[0021] In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular architectures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known methods, devices, circuits, and

[0022] In order to make the above objectives, features and advantages of the present application more clear and comprehensible, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It can be understood that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0023] Embodiments of the present application provide an automatic laminating machine. The automatic laminating machine can apply UV DTF (Direct-to-Film) printing technology, which is a label printing technology. This technology requires the use of glue, UV ink, UV gloss oil, PET film, PVC film and other materials. Its process includes printing various patterns on a PET film coated with a glue layer, and then hot pressing and attaching it with a PVC transfer film and performing transfer printing.

[0024] Among them, the pattern can be printed on the PET film by a UV printer, and the pattern obtains adhesion to the surface of the object through the glue layer on the PET film. The automatic laminating machine can be used to transfer the pattern on the PET film to the PVC film, so that the user can attach it to the surface of the object. Through this technology, the printed design pattern can be transferred to the surface of the object, presenting a three-dimensional effect, similar to a crystal effect, so it is also called a crystal sticker. The UV DTF printed sticker can be applied to various hard surfaces and removed and used without additional processing steps.

[0025] It can be understood that the above is only an application example of the automatic laminating machine, and the automatic laminating machine provided by the embodiments of the present application can also have other applications. The following is described taking the above example as an example, in order to clearly describe the structure of the automatic laminating machine provided by the embodiments of the present application.

[0026] It should be understood that the terms "comprising" and "having" and any variations thereof used in the present specification and claims are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to these processes, methods, products or devices.

[0027] Referring to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the automatic laminating machine provided by some embodiments of the present application, Figure 2 is Figure 1 a schematic diagram of the cross-sectional structure of the automatic laminating machine in the embodiments.

[0028] In some embodiments, the automatic laminating machine 10 includes a laminating hot pressing assembly 100 and a guiding assembly 200. The material to be processed can be sent into the laminating hot pressing assembly 100 from the film feeding side 101 of the laminating hot pressing assembly 100, and the laminating hot pressing assembly 100 is used to heat and press the sent material to achieve lamination. The material is, for example but not limited to, a film body, paper, etc. The guiding assembly 200 is located at the film output side 102 of the laminating hot pressing assembly 100 and is spaced from the laminating hot pressing assembly 100, and is used to guide the output of the material processed by the laminating hot pressing assembly 100. Among them, the film feeding side 101 and the film output side 102 of the laminating hot pressing assembly 100 are two sides of the laminating hot pressing assembly 100, the film feeding side 101 of the laminating hot pressing assembly 100 is the side of the input material, usually the front side, and the film output side 102 of the laminating hot pressing assembly 100 is the side of the output material, usually the rear side.

[0029] Among them, the laminating hot pressing assembly 100 includes a hot pressing roller 110. The hot pressing roller 110 can be a rubber roller with a heating device in the inner core, which completes the attachment operation between the two layers of film by applying pressure at a certain temperature. The laminating hot pressing assembly 100 can include two hot pressing rollers 110, and the two hot pressing rollers 110 can have the same diameter. During the operation of the equipment, the two hot pressing rollers 110 with the same diameter rotate in opposite directions synchronously and have the same angular velocity, which plays a role in heating the material. In other embodiments, the laminating hot pressing assembly 100 can also include more than two hot pressing rollers 110, and multiple hot pressing rollers 110 can cooperate to heat the sent material. Hereinafter, the laminating hot pressing assembly 100 including only two hot pressing rollers 110 is taken as an example for description.

[0030] The guiding assembly 200 includes at least one guiding roller 210. The guiding roller 210 can be a rubber roller used to pull out the material processed by the laminating hot pressing assembly 100. The guiding assembly 200 can include two guiding rollers 210, and the two guiding rollers 210 can have the same diameter. During the operation, the two guiding rollers 210 can rotate in opposite directions synchronously and have the same angular velocity, which plays a role in pulling out the material after lamination from the equipment. In other embodiments, the guiding assembly 200 can also include more than two guiding rollers 210, and multiple guiding rollers 210 can cooperate to guide the output of the material. Hereinafter, the guiding assembly 200 including only two guiding rollers 210 is taken as an example for description.

[0031] Among them, the linear speed of the guide roller 210 can be greater than the linear speed of the hot pressing roller 110, so as to flatten the material during the laminating process, thereby improving the laminating effect and reducing the probability of abnormal phenomena. Film rolling is an abnormal phenomenon in which the film body is wound around the roller body during transportation, which means that the film body is wound around the roller body and cannot be transported smoothly. When the automatic laminating machine 10 rolls up the film, it is often necessary to manually remove the film body. If it is not discovered in time, it may also cause damage to the equipment. Other non-film materials may also be wound around the roller body during transportation.

[0032] The automatic laminating machine 10 may also include a sensing component 300 for sensing whether any abnormalities occur during material conveyance, such as, but not limited to, film curling. Detecting abnormalities in related equipment often relies on manual observation, which is not only inconvenient but also prone to missed detections. The automatic laminating machine 10 provided in this embodiment of the application utilizes the sensing component 300 to automatically sense whether any abnormalities occur in the material, thereby improving the automation of the automatic laminating machine 10 and reducing its reliance on manual operation.

[0033] Among them, the sensing component 300 includes a first sensor 310. The first sensor 310 is arranged between the film coating and hot pressing component 100 and the guide component 200, and is used to sense whether there is any abnormality in the film coating body 13 during the conveying process. Optionally, the first sensor 310 is a photoelectric sensor, which is used to be triggered when an object is sensed. The photoelectric sensor can detect the presence of materials by sensing light, and can then be used to sense the input and output of materials. For example, the first sensor 310 can be a reflective photoelectric sensor, which works by emitting light and detecting light reflected from the surface of an object. When an object enters the detection range of the sensor, the intensity of the reflected light changes, thereby triggering the sensor.

[0034] The first sensor 310 has a detection surface for detecting light. Figure 2 and Figure 3 , Figure 3 yes Figure 1 Schematic diagram of a partial cross-section of the automatic laminating machine in an embodiment. The detection surface of the first sensor 310 can be lower than the first middle tangent 111 of the laminating and hot pressing assembly 100 and the second middle tangent 222 of the guide assembly 200. The first middle tangent 111 is the tangent of the contact ends of the upper and lower hot pressing rollers 110 of the laminating and hot pressing assembly 100. The second middle tangent 222 is the tangent of the contact ends of the upper and lower guide rollers 210 of the guide assembly 200. It should be noted that the number of hot pressing rollers 110 of the laminating and hot pressing assembly 100 and the number of guide rollers 210 of the guide assembly 200 can both be greater than or equal to 2.

[0035] When the material moves normally, it is located on the tangent lines in the middle of the film covering and hot pressing assembly 100 and the guide assembly 200, that is, the first middle tangent line 111 and the second middle tangent line 222. The automatic film covering machine sets the detection surface of the first sensor 310 at a position lower than the first middle tangent line 111 of the film covering and hot pressing assembly 100 and the second middle tangent line 222 of the guide assembly 200, so that the first sensor 310 can emit light upward and receive reflected light, so that when the light emitted by the first sensor 310 reflects on the material, the first sensor 310 can detect the material. During the film covering process, the first sensor 310 will not have a motion phenomenon, and can play a role in detecting the output of the material after the film covering is completed. When the first sensor 310 detects that the material after the film covering is completed has completely passed through the guide assembly 200 and is output, the film covering operation can be automatically stopped. In other embodiments, the first sensor 310 can also be other sensors that can realize the function of sensing the material, such as an ultrasonic proximity sensor.

[0036] Optionally, the first sensor 310 can also be a micro-motion sensor, which is a device or apparatus that can sense the change of a small physical quantity (such as displacement, pressure, vibration, etc.) and convert it into a certain usable signal (such as an electrical signal) output according to a certain rule. The micro-motion sensor can detect the material by sensing the physical quantity change when the material moves to the preset position. In some application scenarios, the micro-motion sensor can be arranged on the movement path of the material to detect the material when it touches the material. The detection surface of the micro-motion sensor can be higher than the first middle tangent line 111 and the second middle tangent line 222, and when the material moves to the position where the micro-motion sensor is located, the material will press the micro-motion sensor downward to trigger the micro-motion sensor. Hereinafter, the first sensor 310 is taken as an example of a photoelectric sensor.

[0037] In some embodiments, the sensing assembly 300 can further include a second sensor 320. The second sensor 320 is arranged on the film feeding side 101 of the film covering and hot pressing assembly 100, and is used to sense whether the material fed into the film covering and hot pressing assembly 100 has an abnormal phenomenon. The second sensor 320 is arranged in a spaced manner with the film covering and hot pressing assembly 100. Optionally, the second sensor 320 is a photoelectric sensor, which is used to trigger when an object is sensed. The photoelectric sensor can detect the conveying of the material by sensing light. For example, the second sensor 320 can be a reflective photoelectric sensor.

[0038] The detection surface of the second sensor 320 can be lower than the first mid-section tangent line 111 of the laminating and hot-pressing assembly 100. The second sensor 320 can emit light upward and receive reflected light. Therefore, when the light emitted by the second sensor 320 hits the material and reflects, the second sensor 320 can detect the material. During the laminating process, the second sensor 320 does not move, and serves to detect the entry of the material into the laminating and hot-pressing assembly 100. Once the second sensor 320 detects the entry of the material into the laminating and hot-pressing assembly 100, the automatic laminating machine 10 can automatically perform the laminating operation.

[0039] Optionally, the first mid-section tangent line 111 and the second mid-section tangent line 222 may coincide. In other embodiments, the second sensor 320 may be another sensor capable of sensing material, such as an ultrasonic proximity sensor or a micro-motion sensor. The first mid-section tangent line 111 and the second mid-section tangent line 222 may also have a certain height difference, for example, the second mid-section tangent line 222 may be slightly lower than the first mid-section tangent line 111.

[0040] The sensing assembly 300 of the embodiment of the present application can utilize the first sensor 310 and the second sensor 320 to perform a composite judgment to achieve autonomous detection of abnormal phenomena that may occur during the material conveying process. The number of the first sensor 310 and the second sensor 320 can be one or more, and the specific number can be set according to actual conditions.

[0041] In some embodiments, the automatic laminating machine 10 includes a main body 400. The main body 400 forms the main support structure of the automatic laminating machine 10 and can be a one-piece structure or composed of multiple shells. The main body 400 can be provided with a feed port 401 for feeding materials into the laminating and hot pressing assembly 100. The feed port 401 is located on the film inlet side 101 of the laminating and hot pressing assembly 100. The main body 400 can also be provided with a discharge port 402 for discharging the laminating material. The discharge port 402 can be located on the side of the guide assembly 200 away from the laminating and hot pressing assembly 100.

[0042] The laminating and hot-pressing assembly 100, the guide assembly 200, and the sensing assembly 300 can all be disposed in the main body 400. The laminating and hot-pressing assembly 100, the guide assembly 200, and the first sensor 310 can be disposed in the interior space of the main body 400. Optionally, the automatic laminating machine 10 can include a mounting plate 311 that is detachably disposed within the main body 400 and located between the laminating and hot-pressing assembly 100 and the guide assembly 200. The first sensor 310 can be mounted on the mounting plate 311. The automatic laminating machine 10 can adjust the position of the detection surface of the first sensor 310 by installing, removing, or replacing mounting plates 311 of different sizes.

[0043] The second sensor 320 can be arranged on a wall body surrounding the feeding port 401. Alternatively, the second sensor 320 can be arranged inside the wall body surrounding the feeding port 401 of the main body 400 and senses the material through a through hole formed on the wall body. The automatic laminating machine 10 can further comprise a light-transmitting sheet 321 arranged on the wall body surrounding the feeding port 401 and covering the second sensor 320 to prevent dust.

[0044] In some embodiments, the automatic laminating machine 10 comprises a material roller 500. The material roller 500 is arranged on the main body 400 and is used to wind the material to be fed into the laminating and hot-pressing assembly 100. The automatic laminating machine 10 can comprise only one material roller 500. When the automatic laminating machine 10 starts to operate, the operator can pull the end of the material wound on the material roller 500 and feed it into the laminating and hot-pressing assembly 100. The material can be directly wound on the material roller 500. The material can also be indirectly wound on the material roller 500, for example, wound on a roller sleeve arranged on the material roller 500.

[0045] The automatic laminating machine 10 can further comprise a cover 600. The cover 600 covers the material roller 500 and prevents the material wound on the material roller 500 from being contaminated by dust. The material roller 500 can be arranged above the laminating and hot-pressing assembly 100 to facilitate the feeding of the material wound on the material roller 500 into the laminating and hot-pressing assembly 100. The cover 600 can cover the laminating and hot-pressing assembly 100 and the guiding assembly 200 to prevent dust. Alternatively, the cover 600 can be made of light-transmitting material, such as acrylic, to facilitate the operator to observe the internal operation of the automatic laminating machine 10. The cover 600 can comprise an arc-shaped plate covering the material roller 500 and a flat plate extending from one end of the arc-shaped plate. The flat plate can cover the laminating and hot-pressing assembly 100. As shown in Figure 1 and Figure 2 As shown in Figs. 6 and 7, the cover 600 can cooperate with the main body 100 to surround other components, so that the internal space of the automatic laminating machine 10 forms a semi-closed space, thereby improving the heating rate.

[0046] It can be understood that all the directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture (as shown in the drawings). If the certain posture changes, the directional indications will also change accordingly.

[0047] In some embodiments, the automatic laminating machine 10 can comprise a guide plate 700. The guide plate 700 is fixed to the main body 400. The guide plate 700 comprises a bearing portion 710 and a guide portion 720 extending from an end of the bearing portion 710. The material roller 500 is disposed above the bearing portion 710. The bearing portion 710 can be used to bear the material disposed on the material roller 500. The guide portion 720 can extend from the end of the bearing portion 710 to above the laminating and hot-pressing assembly 100. The end of the guide portion 720 away from the bearing portion 710 can be an arc-shaped plate deviated towards the laminating and hot-pressing assembly 100, so as to facilitate the material to be fed into the laminating and hot-pressing assembly 100. Alternatively, the guide portion 720 can extend directly above the laminating and hot-pressing assembly 100, i.e. the projection of the guide portion 720 in the vertical direction can fall on the laminating and hot-pressing assembly 100, so as to facilitate the operator to feed the material led out by the guide portion 720 into the laminating and hot-pressing assembly 100.

[0048] In other embodiments, the material roller 500 can also be directly disposed above the laminating and hot-pressing assembly 100, so as to facilitate the material to be fed into the laminating and hot-pressing assembly 100. It can be understood that the temperature above the laminating and hot-pressing assembly 100 is relatively high due to the heat generated during operation. In the present embodiment, the guide portion 720 is disposed above the laminating and hot-pressing assembly 100, and the material roller 500 is disposed on the bearing portion 710 extending from the guide portion 720. Therefore, compared with the embodiment in which the material roller 500 is disposed above the laminating and hot-pressing assembly 100, the temperature of the environment in which the material roller 500 is disposed in the present embodiment is relatively low, and the material wound on the material roller 500 is less likely to be denatured due to the high temperature.

[0049] In some embodiments, the automatic laminating machine 10 further comprises a tensioning rod 510. The tensioning rod 510 can be a straight metal rod. The tensioning rod 510 is disposed above the guide portion 720, and the extension direction of the tensioning rod 510 is parallel to the extension direction of the hot-pressing roller 110. The tensioning rod 510 can be used to make the material drawn out from the material roller 500 to be in a tensioned state when being fed into the laminating and hot-pressing assembly 100.

[0050] Please refer to Figure 2 and Figure 4 , Figure 4 are Figure 1 schematic cross-sectional structure of the automatic laminating machine in the running state.

[0051] As Figure 4As shown, the hot-pressing roller 110 of the film laminating hot-pressing assembly 100 can be used to heat and press the material body 11 and the film 12 fed in to heat and press the laminated material body 11 and the film 12 to achieve film lamination. The material body 11 and the film 12 are used to enter the film laminating hot-pressing assembly 100 from the film feeding side 101 of the film laminating hot-pressing assembly 100 and are heated and pressed in the film laminating hot-pressing assembly 100 to form a film laminated body 13, which is used to be output to the film output side 102 of the film laminating hot-pressing assembly 100. It can be understood that the material mentioned above can be the material body 11, the film 12 or the film laminated body 13.

[0052] In the above embodiment, the material body 11 is a PET film coated with a glue layer, the film 12 is a PVC transfer film, and the film laminating hot-pressing assembly 100 can hot-press and attach the material body 11 and the film 12 and perform transfer printing to transfer the pattern on the material body 11 to the film 12 to form the film laminated body 13, which is a UV DTF printed sticker. It should be noted that the material body 11 can be but is not limited to a film body, and the material body 11 can also be paper or other materials that can be used for film lamination.

[0053] In the above embodiment, the film 12 to be fed into the film laminating hot-pressing assembly 100 can be arranged on the material roller 500, for example, directly wound on the material roller 500, or wound on a roller sleeve arranged on the material roller 500. The material body 11 can be manually fed into the film laminating hot-pressing assembly 100 when film lamination is performed. As shown in Figure 4 In the above embodiment, the film 12 can be wound on the material roller 500 to form a film roll, i.e., a roll of film 12, and the bottom end of the film roll can be higher than the top end of the tensioning rod 510. The tensioning rod 510 is used to keep the film 12 drawn out of the material roller 500 in a tensioned state to avoid unevenness of the film 12 during conveying. When the film 12 is fed into the film laminating hot-pressing assembly 100, the film 12 can be pulled up to the top end of the tensioning rod 510 to be taut and then bent down to be fed into the film laminating hot-pressing assembly 100 along the guide portion 720. The material body 11 can be attached to the film 12 in a tensioned state before being fed into the film laminating hot-pressing assembly 100 and fed into the film laminating hot-pressing assembly 100 together.

[0054] In the above embodiment, the guide portion 720 can be used to guide the film 12 drawn out of the material roller 500 to a position between the material feeding side of the film laminating hot-pressing assembly 100 and the side of the second sensor 320 close to the film laminating hot-pressing assembly 100 to feed the film 12 into the film laminating hot-pressing assembly 100 without triggering the second sensor 320. The second sensor 320 can be used to sense whether the material body 11 is wound on the hot-pressing roller 110. The first sensor 310 can be used to sense whether the film laminated body 13 has abnormal phenomenon during conveying.

[0055] Please refer to Figure 4 and Figure 5 , Figure 5Figure 1 is a schematic diagram of a partial structure of an automatic laminating machine provided by some embodiments of the present application.

[0056] In some embodiments, the automatic laminating machine 10 can further comprise a triggering assembly 800, which comprises a first processor 810 and a first control panel 820 electrically connected. The first processor 810 and the first control panel 820 can be an integrated structure, for example, a circuit board. The first processor 810 and the first control panel 820 can also be a split structure, which can be selected according to actual conditions.

[0057] The first processor 810 can be electrically connected with the first sensor 310, and the first processor 810 can be configured to send a first abnormal signal to the first control panel 820 when the triggering time of the first sensor 310 exceeds a first preset time. The first control panel 820 can be configured to execute a corresponding preset instruction when receiving the first abnormal signal.

[0058] The first processor 810 can also be electrically connected with the second sensor 320, and the first processor 810 can be configured to send a second abnormal signal to the first control panel 820 when the triggering time of the second sensor 320 exceeds a second preset time. The first control panel 820 can be configured to execute a corresponding preset instruction when receiving the second abnormal signal.

[0059] The first processor 810 can also be electrically connected with the first sensor 310 and the second sensor 320 respectively, and be configured to send a third abnormal signal to the first control panel 820 when the second sensor 320 is triggered and the triggering time does not exceed the second preset time, and the first sensor 310 does not trigger for more than a third preset time. It can be understood that the two conditions in the above judgment logic only require to be met, and do not require to be met at the same time point. The first control panel 820 can be configured to execute a corresponding preset instruction when receiving the third abnormal signal.

[0060] The determination of the starting point of the calculation of the non-triggering time of the second sensor 320 can rely on the triggering condition of the first sensor 310. In some embodiments, the first processor 810 can start calculating the non-triggering time of the first sensor 310 when the second sensor 320 is triggered. That is, the starting point of the calculation of the non-triggering time period of the first sensor 310 can be when the second sensor 320 is triggered. In other embodiments, the starting point of the calculation of the non-triggering time period of the first sensor 310 can also be set to other time according to needs, for example, set to start calculating after a certain time after the second sensor 320 is triggered, which can be the time required for one end of the material body 11 to be sensed by the second sensor 320 to enter the guiding assembly 200 after being laminated.

[0061] It should be noted that the first processor 810 can have the above three configurations when the first processor 810 is electrically connected with the first sensor 310 and the second sensor 320 respectively. The first control panel 820 can be configured to execute a corresponding preset instruction when receiving a first abnormal signal, a second abnormal signal or a third abnormal signal. The preset instructions corresponding to the three abnormal signals can be the same or different. The first processor 810 can also have one or two of the above three configurations, which can be set as needed. The first preset time, the second preset time and the third preset time described above can be set according to actual conditions and are not specifically limited.

[0062] The abnormal phenomenon corresponding to the first abnormal signal is, for example, that the film body 13 is rolled in the guide assembly 200, that is, the film body 13 is wound on the guide roller 210. When the film body 13 is rolled in the guide assembly 200, the guide assembly 200 cannot smoothly output the film body 13 completely, and at this time, the existence of the film body 13 that fails to be output causes the first sensor 310 to be triggered for a long time. When the triggering time of the first sensor 310 exceeds the first preset time, the first processor 810 sends a first abnormal signal to the first control panel 820. The first control panel 820 executes a corresponding preset instruction when receiving the first abnormal signal.

[0063] The abnormal phenomenon corresponding to the second abnormal signal is, for example, that the material body 11 is wound on the hot-pressing roller 110. When the material body 11 is wound on the hot-pressing roller 110, the film hot-pressing assembly 100 cannot smoothly output the material body 11 completely, and at this time, the existence of the material body 11 that fails to be output causes the second sensor 320 to be triggered for a long time. When the triggering time of the second sensor 320 exceeds the second preset time, the first processor 810 sends a second abnormal signal to the first control panel 820. The first control panel 820 executes a corresponding preset instruction when receiving the second abnormal signal.

[0064] The abnormal phenomenon corresponding to the third abnormal signal is, for example, that the film body 13 fails to enter the guide assembly 200 smoothly and is accumulated between the film output sides 102 of the film hot-pressing assembly 100. At this time, since the film body 13 fails to be further transported, the first sensor 310 cannot sense the film body 13 and thus is not triggered all the time. Since the material body 11 and the film 12 have completely entered the film hot-pressing assembly 100, the second sensor 320 is triggered and then extinguished, and the triggering time thereof does not exceed the second preset time. After the second sensor 320 is triggered and the triggering time does not exceed the second preset time, when the first sensor 310 is not triggered for more than the third preset time, the first processor 810 sends a third abnormal signal to the first control panel 820, and the first control panel 820 executes a corresponding preset instruction when receiving the third abnormal signal.

[0065] It should be noted that the above abnormal phenomena are only examples and do not limit all abnormal phenomena that may occur when the automatic laminating machine 10 is running. For example, the abnormal phenomenon corresponding to the first abnormal signal can also be that the laminating body 13 is stacked on the film outlet side 102 of the laminating hot pressing assembly 100, i.e. the abnormal phenomenon corresponding to the third abnormal signal in the above example. Specifically, which abnormal signal is triggered by the abnormal phenomenon can be determined by factors such as the distance between the first sensor 310 and the laminating hot pressing assembly 100, the width of the laminating body 13, etc.

[0066] The embodiment of the present application can be designed as a small-sized product based on the above structure, and is used for laminating the material body 11 and the film 12 with small width. Since the material body 11 and the film 12 have small width, the laminating hot pressing assembly 100 and the guiding assembly 200 can pass through in a short time when no abnormal phenomenon occurs. Therefore, when the triggering time of the first sensor 310 and the second sensor 320 is long, it can be determined that an abnormal phenomenon occurs.

[0067] Please continue to refer to Figure 5 .

[0068] In some embodiments, the automatic laminating machine 10 can include a switch assembly 900. The switch assembly 900 is electrically connected with the laminating hot pressing assembly 100 and the guiding assembly 200, respectively. The switch assembly 900 can be electrically connected with the second sensor 320 and configured to start the laminating hot pressing assembly 100 and the guiding assembly 200 when the second sensor 320 is triggered. The switch assembly 900 can also be electrically connected with the first sensor 310 and configured to close the laminating hot pressing assembly 100 and the guiding assembly 200 when the first sensor 310 is triggered and the triggering time does not exceed the fourth preset time, and the first sensor 310 is not triggered for more than the fifth preset time. The fourth preset time is greater than the time required for the laminating body 13 to completely pass through the guiding assembly 200 and less than the first preset time. The specific values of the fourth preset time and the fifth preset time can be set according to actual conditions and are not specifically limited. The switch assembly 900 can be electrically connected with at least one of the first sensor 310 and the second sensor 320 and have at least one of the above two configurations. Hereinafter, the switch assembly 900 is electrically connected with the first sensor 310 and the second sensor 320, respectively, and has at least one of the above two configurations.

[0069] Optionally, the switch assembly 900 can include a second processor 910 and a second control panel 920, the second processor 910 is electrically connected with the first sensor 310 and the second sensor 320 respectively, and the second control panel 920 is electrically connected with the second processor 910, the film hot pressing assembly 100 and the guide assembly 200 respectively. Among them, the second processor 910 is used to send corresponding indication signals to the second control panel 920 according to the triggering conditions of the first sensor 310 and the second sensor 320, and the second control panel 920 is used to control the film hot pressing assembly 100 and the guide assembly 200 to start or stop according to the received indication signals.

[0070] When the material body 11 is sent into the film hot pressing assembly 100, the second sensor 320 triggers, at this time the second processor 910 sends a first indication signal to the second control panel 920, and after the second control panel 920 receives the first indication signal, it controls the film hot pressing assembly 100 and the guide assembly 200 to start, realizing the automatic start of the automatic film laminating machine 10.

[0071] When the film body 13 passes through the guide assembly 200 smoothly, the first sensor 310 triggers first and then extinguishes due to sensing the passing of the film body 13, and then after a period of time after extinguishing, the second processor 910 sends a second indication signal to the second control panel 920, and after the second control panel 920 receives the second indication signal, it controls the film hot pressing assembly 100 and the guide assembly 200 to stop, realizing the automatic shutdown of the automatic film laminating machine 10.

[0072] In some embodiments, as shown in Figure 5 The first control panel 820 can be electrically connected with the second control panel 920. The preset instructions executed by the first control panel 820 corresponding to any one or more of the first abnormal signal, the second abnormal signal and the third abnormal signal can be sending a third indication signal to the second control panel 920. After the second control panel 920 receives the third indication signal, it controls the film hot pressing assembly 100 and the guide assembly 200 to stop, realizing the automatic shutdown of the automatic film laminating machine 10.

[0073] In other embodiments, the first control panel 820 can also be electrically connected with the film hot pressing assembly 100 and the guide assembly 200 respectively, and the preset instructions executed by the first control panel 820 can be directly controlling the film hot pressing assembly 100 and the guide assembly 200 to stop. The preset instructions executed by the first control panel 820 can also be other instructions, for example, the preset instructions for sending a prompt signal, and for example, the preset instructions for controlling the film hot pressing assembly 100 and the guide assembly 200 to stop and sending a prompt signal at the same time.

[0074] It is to be understood that the terms used in the specification and the appended claims are intended to describe particular embodiments only and are not intended to limit the present application. As used in the specification and the appended claims, the singular forms "a," "an" and "the" are intended to include plural forms as well, unless the context clearly indicates otherwise. As used in the description of the application the terms "first," "second," and the like do not imply any relative importance. Thus, features identified as "first," "second," etc. can implicitly or explicitly include one or more of the features so identified. As used in the description of the application the term "plurality" means two or more, unless otherwise specifically indicated.

[0075] Referring to Figure 2 and Figure 6 , Figure 6 is an exploded view of an automatic laminating machine according to some embodiments of the present application.

[0076] In some embodiments, the guiding assembly 200 can include two guiding rollers 210 rotating in opposite directions to drive the film 13. Of course, the number of guiding rollers 210 is not limited to two. The guiding rollers 210 can include protrusions 211 and recesses 212 arranged alternately along the length direction. As shown in Figure 2 the cross section of the guiding rollers 210 can be ring-shaped. The radial dimension of the protrusions 211 can be larger than that of the recesses 212. The protrusions 211 can be higher than the recesses 212 on the outer surface of the guiding rollers 210. The protrusions 211 are used to contact the film 13.

[0077] With this design, the guiding rollers 210 can form a cross section similar to a gear, and the outer profile of the guiding rollers 210 is similar to a set of cross-engaged gears. The guiding rollers 210 contact the film 13 with the protrusions 211, which can reduce the contact area between the guiding rollers 210 and the film 13, and thus reduce the friction. This can reduce the probability of film rolling when the film 13 is conveyed, and can reduce the static electricity generated during the conveying of the film 13.

[0078] Optionally, the guiding assembly 200 includes two guiding rollers 210, and the protrusions 211 of one guiding roller 210 are arranged corresponding to the recesses 212 of the other guiding roller 210. For example Figure 6 as shown in the protrusions 211 of the lower guiding roller 210 can be opposite to the recesses 212 of the upper guiding roller 210.

[0079] The protruding portion 211 of one of the two guide rollers 210 can be at least partially opposite to the recessed portion 212 of the other. In some embodiments, the protruding portion 211 and the recessed portion 212 of the two guide rollers 210 can be staggered.

[0080] Please refer to Figure 1 and Figure 6 .

[0081] In some embodiments, the cover 600 can cover the material roller 500 and be rotatably arranged on the main body 400, so that the cover 600 can be opened or closed as needed, for example, opened when the internal components of the automatic film covering machine 10 are installed or disassembled, for example, opened when the operator observes the internal situation of the automatic film covering machine 10, and for example, closed when the automatic film covering machine 10 is running.

[0082] Optionally, both ends of the cover 600 can be provided with rotating columns 610, and the main body 400 can be provided with corresponding rotating holes 601. The rotating columns 610 can be inserted into the rotating holes 601 and form a rotating fit, so that the cover 600 can rotate relative to the main body 400. In other embodiments, the cover 600 can also be rotatably connected to the main body 400 by other means, for example, by a hinge connection.

[0083] Please refer to Figure 7 and Figure 8 , Figure 7 is Figure 6 a partial exploded structure schematic view of the automatic film covering machine in the embodiment, Figure 8 is Figure 6 a partial cross-sectional structure schematic view of the automatic film covering machine in the embodiment.

[0084] In some embodiments, the automatic film covering machine 10 can include a mounting piece 520. The mounting piece 520 is arranged on the main body 400 and can be connected to one end of the material roller 500, for improving the assembly stability of the material roller 500. The mounting piece 520 can include a pressing portion 521 that presses the end portion of the material roller 500.

[0085] Optionally, one end of the mounting piece 520 can be rotatably arranged on the main body 400, and the other end can form a connecting portion 522 for detachable connection with the main body 400. The portion between the two ends of the mounting piece forms the pressing portion 521 that presses the end portion of the material roller 500. In some embodiments, the pressing portion 521 can be arc-shaped, and the shape of the pressing portion 521 can be adapted to the end portion of the material roller 500. The arc-shaped pressing portion 521 can cover and press the end portion of the material roller 500. In other embodiments, the pressing portion 521 can also be other shapes that can limit the material roller 500.

[0086] The main body 400 can be provided with a mounting groove 403, and the mounting member 520 can be rotatably connected to one end of the main body 400 and can be embedded in the mounting groove 403. The two opposite side walls of the mounting groove 403 can be provided with a first mounting hole 411, and the mounting member 520 is provided with a corresponding second mounting hole 412. The automatic film laminating machine 10 further comprises a mounting shaft 413, which can be inserted into the first mounting hole 411 and the second mounting hole 412 to realize the rotatable connection between the mounting member 520 and the main body 400. In other embodiments, the mounting member 520 can also be rotatably connected to the main body 400 by other means, for example, one of them protrudes a column inserted into the other.

[0087] Optionally, as shown in Figure 8 The connecting portion 522 provided on the other end of the mounting member 520 can be a buckle, and the main body 400 can be provided with a corresponding clamping hole 404, and the connecting portion 522 can be clamped with the main body 400 by being inserted into the clamping hole 404, so that the mounting member 520 can be detachably connected to the main body 400 by the connecting portion 522. In other embodiments, the connecting portion 522 can also be other structures that can be detachably connected to the main body 400, such as a screw.

[0088] The automatic film laminating machine 10 of the embodiment can separate the connecting portion 522 of the mounting member 520 from the main body 400 when installing or dismounting the material roller 500, and then rotate the mounting member 520 to open it, and then the material roller 500 can be installed on the main body 400; After the material roller 500 is installed, the automatic film laminating machine 10 can rotate the mounting member 520 in the opposite direction to connect the connecting portion 522 to the main body 400, so that the mounting member 520 can clamp the material roller 500 with the main body 400, provide a resistance to the material roller 500, so that the material roller 500 can better cooperate with the tensioning rod 510 to form a tensioning force, and avoid the film 12 from loosening.

[0089] In other embodiments, the material roller 500 of the automatic film laminating machine 10 can also be directly detachably connected to the main body 400, for example, the material roller 500 can be clamped with the main body 400.

[0090] Please refer to Figure 9 , Figure 9 is an exploded structural schematic view of the automatic film laminating machine provided by some embodiments of the application.

[0091] In some embodiments, the main body 400 can include a housing 410 and a base 420. The devices of the automatic film laminating machine 10 can be mounted on the base 420. The housing 410 can be sleeved on the base 420 to beautify the appearance of the automatic film laminating machine 10 while protecting the devices mounted on the base 420. The automatic film laminating machine 10 further includes a motor 430. The motor 430 can be arranged at one end of the base 420. The motor 430 can be connected with the heat-pressing rollers 110 and the guide rollers 210 as shown in FIG. 1, for driving the heat-pressing rollers 110 and the guide rollers 210 to rotate. Each heat-pressing roller 110 and each guide roller 210 can rotate synchronously under the action of the motor 430. Figure 6

[0092] The film laminating process of the embodiments of the present application can include: first, the film 12 is drawn out from the film roll formed by the film 12 on the feed roller 500 and is pulled up to the tensioning rod 510 to enter a tensioning state, and then is sent into the film laminating heat-pressing assembly 100 through the guide portion 720; second, the material body 11 is manually sent into the film laminating heat-pressing assembly 100 in a laminated manner with the film 12, so that the material body 11 and the film 12 automatically form a film-laminated body 13 under the action of the film laminating heat-pressing assembly 100; and third, the formed film-laminated body 13 can be further output under the action of the guide assembly 200.

[0093] In the film laminating process, the automatic film laminating machine 10 can control the film laminating heat-pressing assembly 100 and the guide assembly 200 to start through the switch assembly 900 when the second sensor 320 is triggered. The automatic film laminating machine 10 can control the film laminating heat-pressing assembly 100 and the guide assembly 200 to stop through the switch assembly 900 when the first sensor 310 is triggered and the triggering time does not exceed the fourth preset time, and the first sensor 310 is not triggered after the fifth preset time.

[0094] If the material body 11 fails to pass through the film laminating heat-pressing assembly 100 successfully, for example, is wound on the heat-pressing roller 110, the second sensor 320 will be triggered for a long time, and the triggering assembly 800 will execute the preset instruction corresponding to the second abnormal signal. If the material body 11 can pass through the film laminating heat-pressing assembly 100 successfully, and the film-laminated body 13 fails to pass through the guide assembly 200 successfully, for example, is wound in the guide assembly 200, the first sensor 310 will be triggered for a long time, and the triggering assembly 800 will execute the preset instruction corresponding to the first abnormal signal. If the film-laminated body 13 fails to be sent into the guide assembly 200, for example, is accumulated on the film outlet side 102 of the film laminating heat-pressing assembly 100, the second sensor 320 will be triggered and then extinguished, and the first sensor 310 will not be triggered, and the triggering assembly 800 will execute the preset instruction corresponding to the third abnormal signal.

[0095] ​It should be noted that when the material is wound on the corresponding roller body (hot pressing roller 110 or guide roller 210) of the film covering and hot pressing assembly 100 or the guide assembly 200, due to the limited torque of the motor 430, if the roller body is wound with too much film, the motor 430 will be stuck, so the material cannot be completely wound into the roller, and the deformation amount of the roller body is also limited, so the material that can be wound on the roller body is also limited. Therefore, when the material is wound on the roller body, a part of the material cannot be fed into the film covering and hot pressing assembly 100 or the guide assembly 200, thereby causing the first sensor 310 or the second sensor 320 to be triggered for a long time.

[0096] The embodiment of the present application sets the first sensor 310 and the second sensor 320, and uses the film covering and hot pressing assembly 100, the guide assembly 200, the trigger assembly 800 and the switch assembly 900 matched therewith, so as to realize the automatic film covering function and autonomously judge various abnormal conditions, thereby significantly reducing the intervention rate of the operator and improving the use experience of the operator.
