Description

Technical Field

[0001] The utility model relates to the technical field of printing transfer equipment, in particular to a transfer equipment. Background Art

[0002] Transfer equipment, also called transfer machine, is a device that can transfer and composite paper surface and film surface to form transfer paper or composite paper with metallic or laser luster.

[0003] When producing transfer paper or composite paper, the existing transfer equipment usually directly combines the aluminized material film (hereinafter referred to as the material film) and the white card base paper (hereinafter referred to as the base paper) under the action of glue and pressure through a pressure roller and a gluing device to make the required transfer paper or composite paper. Under normal circumstances, such equipment can be adapted to ordinary paper with low printing requirements. However, when preparing some thin paper with low thickness requirements, low-weight base paper is required. After such low-weight base paper is bonded to the film surface of the material film, it is easy to deform and bend under the influence of the tension of the film surface, resulting in poor flatness and stability of the finished product. In addition, such paper is also prone to fluctuations or unstable stretching during the gluing, transfer and compounding processes, which seriously affects the quality of the finished product. Utility Model Content

[0004] In view of this, in order to solve the problems of paper flatness and instability caused by the influence of film tension, the utility model provides a transfer device that can ensure high flatness and strong stability of the finished product.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A transfer device is defined as a side for winding up a coil as a front end, and a side for unwinding the coil as a rear end, the transfer device comprising: an unwinding device for unwinding a base paper; an attachment device comprising a first unwinding roller, a second unwinding roller and a laminating mechanism, the first unwinding roller and the second unwinding roller being used for unwinding a base paper and a material film respectively, the laminating mechanism being arranged at the rear ends of the first unwinding roller and the second unwinding roller, the base paper and the material film being led to the laminating mechanism for laminating; a transfer and compounding device being arranged at the rear ends of the unwinding device and the laminating mechanism, the transfer and compounding device comprising two transfer and compounding rollers, the two transfer and compounding rollers being arranged tangent to each other, the base paper and the paper material laminated by the laminating mechanism passing through the tangent part of the two transfer and compounding rollers, being transferred and compounded by the two transfer and compounding rollers, and the base paper being separated.

[0007] In the above technical scheme, the first unwinding roller is used to unwind the base paper, and the second unwinding roller is used to unwind the material film. The base paper and the material film pass through the laminating mechanism together. Under the pressure of the laminating mechanism, the base paper and the material film are closely attached to each other, and the base film layer of the material film can be attached to the base paper, so that the material film reaches a state of stable tension. When it is subsequently combined with the base paper, it can effectively avoid the deformation and bending of the paper caused by unstable tension on the surface of the material film, and improve the flatness and stability of the finished product; after the laminating mechanism is pressed, the base paper and the attached material film are both led to the transfer composite device, which includes two tangentially arranged transfer composite rollers. The base paper and the material film pass through the tangent part of the two transfer composite rollers, and the base paper and the material film are combined under pressure through the transfer composite rollers, and the base paper is peeled off.

[0008] It should be noted that the material film adopts one of the transfer film and the composite film. When producing transfer paper, the transfer film is selected as the material film, and when producing composite paper, the composite film is selected as the material film. Among them, the transfer film and the composite film are both laminated structures, and the laminated structures of the two are the same. The main difference is that the base film layer of the transfer film can be peeled off and recycled, and it is a recyclable material film, and the base film layer of the composite film cannot be peeled off, and it is a non-recyclable material film.

[0009] Furthermore, the pressing mechanism comprises at least two pressing rollers, and the pressing rollers are arranged tangentially.

[0010] In the above technical solution, the pressing rollers are arranged tangentially, and the base paper and the material film pass through between the pressing rollers. Under the pressure of the pressing rollers, the air is exhausted, so that the base paper and the material film are closely attached.

[0011] Furthermore, a fitting detection device is provided at the rear end of the pressing mechanism.

[0012] In the above technical solution, the bonding detection device is used to monitor the bonding between the base paper and the material film to ensure that the base paper and the material film are completely bonded to avoid bubbling and wrinkling, and to prevent subsequent invalid processes.

[0013] Furthermore, a glue applying device is provided between the laminating detection device and the transferring and compounding device, and the glue applying device is used to apply glue on the surface of the paper material after being pressed by the pressing mechanism.

[0014] In the above technical solution, the glue applying device is used to apply glue on the surface of the bottom glue layer of the material film.

[0015] Furthermore, the glue applying device comprises a glue coating roller, a transfer roller and a glue tank, the glue coating roller is arranged tangentially to the transfer roller, and the glue coating roller is arranged in the glue tank.

[0016] In the above technical solution, one side of the glue coating roller is placed in a glue tank storing glue, and the material film combined with the base paper passes between the glue coating roller and the transfer roller, and the glue coating roller evenly coats the glue on the bottom glue layer of the material film by rolling.

[0017] Furthermore, a base paper recovery device and a winding device are provided at the rear end of the transfer and compound device, the base paper separated by the transfer and compound device is introduced into the base paper recovery device, and the remaining paper materials are introduced into the winding device.

[0018] In the above technical scheme, the transfer and laminating device can peel off the base paper while laminating the bottom paper and the base paper with the material film attached thereto, and the base paper is sent to the base paper recovery device for recovery, thereby realizing the reuse of the base paper and avoiding increasing the papermaking cost. The paper material after peeling off the base paper is sent to the winding device for the next step of processing.

[0019] Furthermore, the base paper recovery device comprises a guide roller and a base paper recovery roller, the guide roller is arranged between the transfer and compounding device and the base paper recovery roller, and the base paper recovery roller is used to roll up the base paper.

[0020] In the above technical solution, the guide roller is arranged at the front end of the base paper recovery roller for guiding the base paper, and the base paper recovery roller is used to roll up the base paper to complete the recovery of the base paper.

[0021] Furthermore, the winding device comprises a separation mechanism and a winding mechanism, and the separation mechanism is arranged between the transfer and compounding device and the winding mechanism.

[0023] Furthermore, the separation device comprises a separation roller, and the separation roller is used to separate the paper material after the base paper is separated by the transfer and compounding device.

[0024] In the above technical solution, when producing transfer paper, the separation roller can peel off the base film layer in the material film to obtain finished transfer paper. When producing composite paper, the paper directly passes through the separation roller. The separation roller does not separate the paper and only plays a transition and guiding role.

[0025] Furthermore, the winding mechanism comprises at least one winding roller, and the winding roller is arranged at the rear end of the separation roller.

[0026] In the above technical solution, at least one winding roller is provided, and the winding roller is used to wind up the peeled base film layer and the finished paper.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] The present application is provided with a supporting device, which includes a first unwinding roller, a second unwinding roller and a pressing mechanism. The pressing mechanism can press the base paper and the material film released by the two unwinding rollers, and attach the base film layer of the material film to the base paper, so that the material film can reach a state of stable tension. When it is subsequently combined with the base paper, it can effectively avoid deformation and bending of the paper caused by unstable tension on the surface of the material film. Compared with the existing technology, the flatness and stability of the finished product can be significantly improved; in addition, the transfer and compounding device can peel off the base paper combined with the material film. Since the base paper and the material film are physically bonded and separated, the surfaces of both are not damaged, so the peeled base paper can be rolled up and reused, which will not increase the papermaking cost.
