Description

Card Laminator

technical field

The utility model relates to a laminating machine, in particular to a card laminating machine.

Background technique

The laminating machine is a special equipment used to set a film on the surface of the processed parts such as boards and papers, so as to form a waterproof, anti-counterfeiting and other protective film on the processed parts. According to different working principles, laminating machines are mainly divided into instant coating laminating machines and pre-coating laminating machines. Among them, the ready-to-coat laminating machine includes three working parts: gluing, drying, and hot pressing. It has a wide application range and stable and reliable processing performance. It is currently the most widely used laminating equipment in China. The pre-coating laminating machine has no gluing and drying parts, small size, low cost, and flexible and convenient operation. It is not only suitable for laminating processing of large-scale printed matter, but also suitable for laminating of small-batch and scattered printed matter such as automated desktop office systems. processing, and thus widely used.

According to the different workpieces and processing requirements, the requirements for laminating machines are quite different. For example, for card-type workpieces such as business cards and certificates, the laminating machine needs to be able to form a uniform film on the surface of the workpiece to avoid problems such as film damage. For decorative plate parts such as glass and aluminum-plastic panels, it is only necessary to form a protective film on the surface, and because the film material is relatively thick, there is no need to pay too much attention to the uniformity of the coating and the thickness of the film. Cosmetic issues such as strain, which would otherwise unnecessarily increase production costs. In this case, laminators for different applications are significantly different in structure and are often difficult to transfer technically to each other.

For the card laminating machine, as mentioned above, there are still many problems, resulting in the obtained products not meeting the demand. On the one hand, the existing card laminating machine has the phenomenon of film leakage or uneven coating after a period of use, making it impossible to protect the card or prevent counterfeiting; on the other hand, the film formed on the surface of the card has Scratches make the card less aesthetically pleasing.

In view of this, it is necessary to provide a card laminating machine to solve the above-mentioned problems in the prior art.

Utility model content

The technical problem to be solved by the utility model is to provide a card laminating machine, which can effectively reduce the possibility of film leakage or uneven film coating.

In order to solve the above technical problem, it is first necessary to analyze the cause of the technical problem. In production practice, after long-term observation and statistics, the existing film laminating machine does not leak film or film unevenly in the initial stage of use. And as the number of times of use increases, this problem becomes more and more significant. The key step of lamination is to press the film tape on the card with a hot pressing roller, so that the film on the film tape is peeled off and attached to the card. It can be seen that whether the hot pressing roller can apply uniform and constant pressure has a great influence on the uniformity of the coating. Furthermore, since the hot pressing roller of the existing card laminating machine is a cantilever structure (one-side drive), there is inevitably deformation during the operation process. Therefore, after a period of use, the following problems will occur: the part far away from the driving end Under the reaction force, it is gradually deformed and it is difficult to fit the film tape well, so it is impossible to apply uniform pressure, which eventually leads to leakage of the film or uneven coating.

On this basis, the utility model provides a card laminating machine, which includes a card conveying mechanism, a winding shaft and an unwinding shaft respectively used for retracting and unwinding the film tape, and a machine for hot pressing the film tape To the hot pressing roller on the surface of the card, the hot pressing roller is pivotally connected to the pressing device at both ends in the axial direction, so that the hot pressing roller can be pressed to the film belt through the pressing device.

Preferably, the pressing device includes roller shaft mounting plates opposite and spaced apart, and the hot pressing roller is respectively connected to the roller shaft mounting plate at both ends in the axial direction so as to be pivotally connected to the pressing device.

Preferably, the card laminating machine includes a frame for integrally installing the card conveying mechanism, winding shaft, unwinding shaft, hot pressing roller and pressing device.

Preferably, the frame includes a front panel and a rear panel arranged at intervals, and the extension height of the rear panel is greater than that of the front panel.

Preferably, the card laminating machine includes a linear motor installed on a part of the rear plate that is higher than the front plate, and the linear motor is connected to the heat press roller through the pressing device.

Preferably, the winding shaft and the unwinding shaft are respectively arranged on both sides of the pressing device and connected to a part of the rear board higher than the front board.

Preferably, a protective plate is provided on a side of the pressing device and the hot pressing roller away from the rear plate.

Preferably, the card conveying mechanism is configured to convey the card in a horizontal direction, and the hot pressing roller can be driven by the pressing device to move vertically downward to press against the upper side of the film belt.

Preferably, the card transmission mechanism includes a driving wheel assembly and a driven wheel assembly arranged in parallel horizontally, the driving wheel assembly and the driven wheel assembly respectively include a plurality of wheel parts arranged at intervals, and the axes of each wheel part are parallel to each other.

Preferably, the winding shaft and the unwinding shaft are respectively driven by torque motors, so that the film belt has a constant tension.

Through the above-mentioned technical scheme, the card laminating machine of the utility model applies pressure to the hot pressing roller on both axial sides of the hot pressing roller by the pressing device, so that it can act on the film belt evenly, and during the operation process In the process, both ends of the hot pressing roller are stressed overall, and there is no problem that one side is deformed under the reaction force and cannot be attached to the film tape, thereby effectively reducing the possibility of film leakage or uneven coating.

Other features and advantages of the present utility model will be described in detail in the following specific embodiments.

detailed description

The specific embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the utility model, and are not intended to limit the utility model.

As shown in Figures 1 to 4, a card laminating machine according to a preferred embodiment of the present invention includes a card transport mechanism 1 for transporting cards to be coated, and performing laminating operations on the transport path; for Install the winding reel 2 and unwinding reel 3 of film tape volume, wherein, will be collected by rewinding reel 2 after the film on the film tape released by unwinding reel 3 peels off and sticks on the card; The pressure roller 4 can heat-press the film on the film tape 10 onto the surface of the card by rolling heat pressing on the back side of the film tape 10 (i.e., the side of the film tape 10 that is not provided with the film) (for example, by applying heat Transfer to the film tape 10 so that the film is peeled off and attached to the card).

Wherein, the hot pressing roller 4 is pivotally connected to the pressing device 5 at both ends of the axial direction, and the pressing device 5 can simultaneously apply pressure to the hot pressing roller 4 at both axial ends of the hot pressing roller 4 to implement the above hot pressing craft. The card laminating machine of the utility model can make the hot pressing roller 4 act on the film tape 10 relatively uniformly, thereby the force is uniform everywhere along the axial direction of the hot pressing roller 4, and the film formed on the card is relatively uniform.

In addition, during the operation, since both ends of the hot pressing roller 4 are stressed as a whole, there will be no serious deformation of one end of the hot pressing roller 4 under the reaction force. All parts of the pressure roller 4 are well attached to the film tape 10, thereby effectively preventing the occurrence of the film leakage phenomenon.

The utility model breaks through the shackles of traditional technical thinking, and creatively sets the driving mode of the hot pressing roller 4 to be driven at both ends of the axial direction, thereby obtaining a good coating effect. Specifically, in the traditional understanding, since the pressure required to be applied to the film tape 10 is not significant when the card is laminated, the film is peeled off mainly by providing appropriate heat, but the slight deformation of the heat pressing roller 4 is ignored. That is, it may cause difficult-to-repair problems such as leaking film, which will seriously affect the aesthetics of the card, and even fail to perform the required anti-counterfeiting and protection functions. The utility model is just based on long-term production practice, through continuous observation and statistics, and then analyzes the essential reasons for the phenomenon of uneven coating and film leakage in the prior art, and then proposes the technical solution of the utility model, and obtains Remarkable results.

On this basis, the above-mentioned technical solution of the utility model can be implemented in various preferred ways. For example, as shown in FIG. 3 and FIG. 4 , the pressing device 5 may include roller shaft mounting plates 5 a arranged at a distance from each other, and the axial ends of the hot pressing roller 4 are respectively connected to the roller shaft mounting plates 5 a. Specifically, the hot pressing roller 4 can be provided with an axially penetrating roller shaft, and the roller shaft is fixed or pivotally connected to the roller shaft mounting plate 5a, so that the hot pressing roller 4 can be opposed to each other by frictional force during the transmission of the film tape 10. The roller shaft mounting plate 5a pivots. Optionally, the hot pressing roller 4 may also be formed with protrusions at both ends in the axial direction, and be pivotally connected to the roller shaft mounting plate 5 a through the protrusions and bearings.

Card laminating machines usually use business cards, certificates, etc. as lamination processing parts. In order to meet the requirements of automatic desktop office and easy handling, various functional components can be integrated. For this reason, in the preferred embodiment shown in the figure, a frame 6 is also provided, and the card transport mechanism 1, the winding shaft 2, the unwinding shaft 3, the hot pressing roller 4 and the pressing device 5, etc. can be integrated directly or indirectly installed on the 6 on the rack.

The frame 6 described above may be formed in various appropriate structures. In order to facilitate the installation of various parts and the implementation of the laminating process, the frame 6 preferably includes a front panel 6a and a rear panel 6b arranged at intervals, and the extension height of the rear panel 6b is greater than that of the front panel 6a. For example, the front panel 6a and the rear panel 6b may be fixedly mounted on a common horizontal support. The frame 6 of this preferred structure has multiple advantages, which will be more apparent in the following description in conjunction with further preferred embodiments.

In order to apply pressure to the hot pressing roller 4 through the pressing device 5, an appropriate power mechanism can be provided. The power mechanism can be in various forms capable of driving the pressing device 5, such as a hydraulic cylinder or a rotary drive device (such as a rotary motor) and a transmission device for converting the rotary motion of the rotary drive device into linear motion. In the illustrated embodiment, a linear motor 7 is used as the power mechanism. The linear motor 7 is installed on the part of the rear plate 6b higher than the front plate 6a, and its power output shaft is connected to the drive through the pressing device 5. Hot pressing roller 4. In comparison, the embodiment in which the linear motor 7 is used as the power mechanism has the advantage of simple structure. In addition, it can be seen that the frame 6 is configured to include a front panel 6a and a rear panel 6b with different extension heights, which is conducive to convenient disassembly and assembly of various functional components, making maintenance and replacement of these components easier.

Further, the winding shaft 2 and the unwinding shaft 3 are respectively arranged on both sides of the pressing device 5, and are connected to the part of the rear plate 6b higher than the front plate 6a. On one side of the pressing device 5, the film tape 10 released by the unwinding shaft 3 is well attached to the card under the action of the pressing device 5, and is collected on the winding shaft 2 on the other side, which is not only convenient for the winding shaft 2 and the unwinding shaft 3 The replacement of the upper film tape roll also makes the card laminating machine more beautiful, and the film tape 10 can be opened well and the force is more uniform.

In addition, the hot pressing roller 4 has a relatively high temperature during operation, and operators who directly touch the hot pressing roller 4 and the pressing device 5 may cause burns and other personal injuries. For this reason, a protective plate 8 may also be provided on the side of the pressing device 5 and the hot pressing roller 4 away from the rear plate 6b. The protection plate 8 can be arranged in the same vertical plane as the front plate 6a, and can be equipped with a tensioning wheel (not marked) for tensioning the film belt 10 .

As mentioned above, in addition to the phenomenon of uneven coating and film leakage, there are also aesthetic problems such as the film on the card being scratched in the prior art. In order to solve this technical problem, it is first necessary to analyze its cause. During operation, the film tape 10 is subjected to the pressure of the hot pressing roller 4 and the tension wheel on the one hand, and is constrained by the rewinding shaft 2 and the unwinding shaft 3 on the other hand, both of which may strain the film tape 10 . For this reason, this technical problem can be solved by corresponding means, for example, properly adjust the pressure that the hot pressing roller 4 acts on the film belt 10, and form it in the form of elastic hot pressing. However, it has been proved in practice that this cannot solve the problem of film belt strain well. Then, it is necessary to analyze the constraint of the film tape 10 by the winding reel 2 and the unwinding reel 3 in the prior art. In the traditional technology, the rewinding shaft 2 and the unwinding shaft 3 are usually driven by stepping motors and DC motors, and there is no problem that the film tape 10 will be strained at the beginning of the operation. Yet along with the carrying out of laminating operation, the film tape 10 on the unwinding reel 3 constantly reduces, and the film tape volume diameter is more and more smaller; The film tape 10 on the winding shaft 2 constantly increases, and the film tape volume diameter is increasing, As a result, the tension of the film tape 10 is continuously increased, eventually causing the film tape 10 to be strained and affecting the aesthetics of the film.

On this basis, it is necessary to provide a rewinding and unwinding method capable of adjusting the tension of the film tape 10. For this reason, in a preferred embodiment of the present invention, as shown in FIG. 2, the rewinding shaft 2 and the unwinding shaft 3 Driven by the torque motor 9 respectively, the torque motor 9 can timely adjust the tension of the film tape 10, release and collect the film tape 10 at a relatively constant linear speed, thereby avoiding the generation of stretch marks.

The torque motor 9 can drive the winding shaft 2 and the unwinding shaft 3 to rotate through an appropriate transmission mechanism. In the illustrated embodiment, the transmission mechanism is provided with a deceleration device 11, and the unwinding shaft 3 is driven to rotate through the unwinding shaft transmission gear 12, thereby releasing the film tape roll. The process of collecting the film tape 10 by the reel 3 is also the same, so it will not be described again.

The above improvements have been made to the card laminating machine from the aspects of retracting and unwinding of the film tape 10, hot pressing, etc., but the film tape 10 needs to stick the peeled film on the card in the end. Therefore, a card conveying machine that can transport cards well is provided Mechanism 1 is also of great significance for improving the lamination effect of the card laminating machine.

The card conveying mechanism 1 can convey the card in multiple appropriate directions, and the heat pressing roller 4 heat-presses the film tape 10 onto the card in a vertical direction or a direction with an appropriate inclination angle for lamination. According to a preferred embodiment of the present utility model, the card conveying mechanism 1 is configured to convey the card along the horizontal direction, and the hot pressing roller 4 can be driven by the pressing device 5 to move vertically downward to press against the upper side of the film belt 10 . This facilitates the arrangement of the card transmission mechanism 1. For example, in the preferred embodiment in conjunction with the drawings, the card transmission mechanism 1 includes a driving wheel assembly 1a and a driven wheel assembly 1b arranged in parallel horizontally. The driving wheel assembly 1a and the driven wheel assembly 1b Each includes a plurality of wheel parts (such as rubber wheels) arranged at intervals, and each wheel part can be pivotally connected to the front plate 6a and the rear plate 6b, and its axes can be parallel to each other. The driving wheel assembly 1a can be connected to the track motor 1c by a belt drive, so that it can rotate under the drive of the track motor 1c. At the same time, during the working process, there is friction in the driving wheel assembly 1a, the card, and the driven wheel assembly 1b in sequence, so that the driven wheel assembly 1b also rotates and horizontally transports the card.

In addition, horizontally transported cards help improve lamination uniformity. In addition, the card conveying mechanism 1 may also include a tensioning device (not shown) for tensioning the card during the process of conveying the card.

In order to facilitate the understanding of the utility model, the working process of the card laminating machine provided by the utility model will be briefly described below in conjunction with preferred embodiments.

Driven by the orbital motor 1c, each wheel in the driving wheel assembly 1a rotates. At this time, the card is fed into between the driving wheel assembly 1a and the driven wheel assembly 1b from the card inlet side (the right side as shown in FIG. 4 ) to convey the card in the horizontal direction. After the card enters the card conveying mechanism 1, the card is tensioned by the tensioning device to ensure the accuracy of the lamination.

Simultaneously, unwinding reel 3 and take-up reel 2 are under the drive of torque motor 9 respectively at the both sides of pressing device 5 and hot pressing roller 4 convey film belt 10, and pressing device 5 is driven to hot pressing roller 4 under linear motor 7. The pressure is applied so that it acts on the film strip 10 laterally on the top side of the film strip 10 . During this process, the output torque of the torque motor 9 is gradually adjusted, so that the film belt 10 has a substantially constant linear speed and tension, avoiding the generation of stretch marks. The pressing device 5 synchronously drives the hot pressing roller 4 at both axial ends of the hot pressing roller 4 through the roller shaft mounting plate 5a, so as to prevent one end from deforming under the reaction force and unable to contact the card conveyed by the card conveying mechanism 1 well.

When the card is conveyed directly under the hot pressing roller 4, the film is peeled off from the film belt 10 under the heat and pressure of the hot pressing roller 4 and evenly pasted on the surface of the card. Furthermore, the coated card is sent out from the card outlet side (the left side as shown in FIG. 4 ) of the card delivery mechanism 1, and the coating operation is completed.

The preferred embodiment of the utility model has been described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the specific details of the above-mentioned embodiment. These simple modifications all belong to the protection scope of the present utility model.

In addition, it should be noted that the various specific technical features described in the above specific implementation manners may be combined in any suitable manner if there is no contradiction. In order to avoid unnecessary repetition, the utility model will not further describe various possible combinations.

In addition, any combination of various implementations of the present invention can also be made, as long as they do not violate the idea of the present invention, they should also be regarded as the disclosed content of the present invention.
