Description

Technical Field

[0001] This invention belongs to the field of release film processing technology, and in particular relates to an automatic film application system for a DTF powder spreader. Background Technology

[0002] DTF white ink heat transfer printing involves printing the desired design onto a release film, followed by powder application, shaking, and drying. Finally, a heat press is used to directly transfer the design from the release film onto the garment. This process is very simple and can be completed by one person. Because white ink heat transfer is a direct transfer process, it has low requirements for fabric; almost all fabrics can be used, making it widely applicable. White ink heat transfer products are characterized by vibrant colors and sharp images. Furthermore, no steaming or washing is required after printing, making the process not only simple but also very environmentally friendly. All consumables used in white ink heat transfer are green and environmentally friendly, and it can be used directly on children's products. No waste or wastewater is generated during the printing process, preventing environmental pollution. White ink heat transfer products have a large market share in the low-to-mid-range market, and this technology has become a mainstream development direction in digital printing.

[0003] Currently, there are many types of DTF powder coating machines on the market. All of them require manual pulling of the release film through the powder coating device, and after placement, manual operation is still needed to coat the release film with hot melt powder. This method is cumbersome, highly dependent on manual labor, lacks automation, and is inefficient. Therefore, an automatic film coating system for DTF powder coating machines is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic film application system for DTF powder spreading machines, which solves the problems of existing DTF powder spreading machines on the market that require manual pulling of the release film through the powder spreading device, placement, and continued manual operation to spread hot melt powder onto the release film. This method is cumbersome, highly dependent on manual labor, has low intelligence, and is inefficient.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to an automatic film application system for a DTF powder spreading machine, comprising a front release film position detection device, a front suction roller device, a front suction roller transmission system, a front guide plate, a hot melt powder weighing device, a rear guide film device, a rear guide plate device transmission system, a rear guide plate device position detection device, a rear suction roller device, a rear suction roller transmission system, and a rear release film position detection device. The front suction roller transmission system is located above the front release film position detection device, and the front suction roller device is positioned above the front suction roller transmission system. One side of the front suction roller device is inclined. The system is equipped with a front guide plate, a hot melt powder weighing device below the front guide plate, a rear guide plate device on one side of the front guide plate, a rear guide plate device transmission system on one side of the rear guide plate device, a rear suction roller device on the rear guide plate device, a rear suction roller device transmission system on one side of the rear suction roller device, a rear guide plate device position detection device below the rear guide plate device transmission system, a rear release film position detection device above the rear suction roller device, and a powder spreading device above the front guide plate.

[0007] Furthermore, the position of the front suction roller drive system is adapted to the front suction roller device, and the front suction roller drive system and the front suction roller device cooperate with each other.

[0008] Furthermore, the position of the rear guide film device is adapted to the transmission system of the rear guide film plate device, and the rear guide film device and the transmission system of the rear guide film plate device cooperate with each other.

[0009] Furthermore, the position of the rear suction roller device is adapted to the rear suction roller drive system, and the rear suction roller device and the rear suction roller drive system cooperate with each other.

[0010] Furthermore, the height of the front suction roller device is adapted to the front guide plate.

[0011] Furthermore, after the release film is printed with the desired pattern by the DTF printer, it falls along the paper output platform. When the "upload film" command is clicked on the touch screen, the rear film guide device automatically rotates to the upper limit position and places the release film on the front suction roller device. The release film automatically adheres to the front suction roller. As the DTF printer continues printing, the release film continues to fall. When the front release film position detection device detects the release film, the front suction roller transmission system works, driving the front suction roller to rotate, thereby moving the release film forward.

[0012] Furthermore, when the rear release film position detection device detects the release film, the rear suction roller device starts working, adsorbing the release film onto the rear suction roller. The rear guide plate device automatically returns to the lower limit position, the DTF powder spreader enters automatic mode, the powder spreader starts spreading powder, and at the same time, the film is fed. The release film, wrapped with powder, descends into the hot melt powder weighing device. When the weight of the powder reaches the system set value, the front suction roller device and the front suction roller transmission system automatically shut down.

[0013] Furthermore, when the weight of the hot melt powder reaches the system set value and the front release film position detection device detects the release film, the rear suction roller drive system works to transport the release film into the oven device, thereby achieving the purpose of automatic film feeding.

[0014] The present invention has the following beneficial effects:

[0015] This invention improves powder application efficiency by incorporating a hot melt powder weighing device for precise and rapid powder application. Furthermore, by integrating a front release film position detection device, a front suction roller device, a front suction roller transmission system, a front guide plate, a hot melt powder weighing device, a rear guide plate device, a rear guide plate device transmission system, a rear guide plate device position detection device, a rear suction roller device, a rear suction roller transmission system, and a rear release film position detection device, the DTF powder application machine achieves automatic film application. This system is simple to operate, has low reliance on manual labor, is highly intelligent, and significantly improves work efficiency.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
