Description

Technical Field

[0001] The utility model belongs to the technical field of DTF powder sprinkling machines, and particularly relates to a powder sprinkling device for preventing powder flying in a DTF powder sprinkling machine. Background Technique

[0002] The DTF powder sprinkling machine is one of the key devices in the DTF white ink heat transfer printing process. It is mainly responsible for evenly sprinkling hot melt powder on the printed pattern. The hot melt powder is an indispensable consumable in DTF white ink heat transfer printing and is usually in the form of white powder. It has characteristics such as adhesiveness, high temperature resistance, water wash resistance, and high color fastness. The hot melt powder is in a highly elastic state at room temperature, melts into a viscous flow state after heating, and quickly solidifies, thus firmly transferring the pattern to various materials.

[0003] The hot melt powder can be divided into coarse powder, medium powder, and fine powder according to its particle size. Different specifications of hot melt powder are suitable for different processes and materials. For example, coarse powder is mainly used for flocking transfer, medium powder is mainly used for the powder shaking process of white ink heat transfer printing, and fine powder is more used for dispersion in glue or film saccharification transfer. Generally speaking, the particle size of coarse powder is between 250 - 400um, medium powder is 80 - 250um, and fine powder is less than 80um.

[0004] Currently in the industry, all the hot melt powder used on powder sprinkling machines is bagged hot melt powder, and the powder sprinkling area of the powder sprinkling machine is not completely isolated from the outside of the machine. These hot melt powders have small particle sizes and light weights. When pouring into the powder sprinkling box, the hot melt powder is very easy to float into the air and be inhaled into the human body. For those who have been engaged in this industry for a long time, it is easy to get pneumoconiosis if they are not careful, causing irreversible harm to the human body. To solve the above problems, we propose a powder sprinkling device for preventing powder flying in a DTF powder sprinkling machine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a powder sprinkling device for preventing powder flying in a DTF powder sprinkling machine to solve the existing problems.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a powder sprinkling device for preventing powder flying in a DTF powder sprinkling machine, including a powder sprinkling box. A sealing cover is arranged at the upper end of the powder sprinkling box. A powder feeding port is opened in the middle of the sealing cover. A powder feeding automatic sealing device is arranged below the powder feeding port. A hot melt powder bottle opener is arranged directly below the powder feeding automatic sealing device. The lower end of the hot melt powder bottle opener is fixedly connected to the inner wall of the powder sprinkling box. A powder sprinkling pipe is arranged at the lower end of the powder sprinkling box;

[0008] The powder-feeding automatic sealing device includes a sealing door base, which is fixedly connected to a sealing cover. On both opposite sides inside the sealing door base, there are pin shafts. A sealing door is hinged to the circumferential surface of the pin shafts, and a torsion spring is arranged on the circumferential surface of the pin shafts, and the position of the torsion spring is adapted to the sealing door.

[0009] In one embodiment, there is a bottled hot-melt powder above the sealing cover. The shape and size of the bottle mouth of the bottled hot-melt powder are both adapted to the powder-feeding port, and they cooperate with each other between the bottled hot-melt powder and the powder-feeding port.

[0010] In one embodiment, the cross-section of the powder-sprinkling box is a funnel-shaped structure, which is convenient for the rapid feeding of the hot-melt powder.

[0011] The utility model has the following beneficial effects:

[0012] When the utility model is in use, first invert the bottled hot-melt powder, insert the bottle mouth into the powder-feeding port of the sealing cover. At this time, the powder-feeding automatic sealing device receives a downward force, and the sealing door of the powder-feeding automatic sealing device automatically opens. When the sealing of the bottled hot-melt powder passes through the hot-melt powder bottle opener, the hot-melt powder bottle opener pierces the sealing, and the hot-melt powder inside the bottled hot-melt powder automatically flows into the powder-sprinkling box. During the process of pulling out the bottle after pouring the powder, for the powder-feeding automatic sealing device, due to the force provided by the torsion spring, the sealing door will automatically close the powder-feeding port as the bottled hot-melt powder leaves.

[0013] By setting the powder-feeding automatic sealing device, the utility model avoids the hot-melt powder floating into the air when pouring the powder, so as to prevent it from being inhaled into the human body and causing irreversible harm to the human body.

[0014] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
