Therefore, UV printers are widely used in the printing of various materials. When printing materials, a feeding device is required to transport the materials to be printed to the printing platform of the printer.

[0003] However, in the prior art, when printing hard media such as corrugated cardboard, plastic plates, resin plates, gypsum boards and other hard material plates, it is usually necessary for workers to take the materials one by one and place them in the feeding port of the printer or on the printing table for printing. The operation is rather troublesome, the feeding speed is slow, which is likely to affect the printing efficiency of the printer. And because the workers hold the materials and place them in the feeding port of the printer or on the printing table for printing, it is difficult to guide and calibrate the angle of the materials during the feeding process. During printing, it is easy to increase the rejection rate of printed products and affect the quality of printed products. Summary of the Utility Model

[0011] Preferably, cushion blocks are arranged at the four corners of the bottom end face of the mounting frame, and rubber anti-slip gaskets are arranged at the bottoms of the cushion blocks.

[0012] Preferably, a square groove is formed in the middle of the top end face of the mounting frame. The material frame is in an interference fit in the square groove. A pair of assembly plates are arranged on the material frame, and assembly holes are formed in the assembly plates. The material frame is located between the pair of second electric linear modules.

[0016] The utility model has the following beneficial effects:

[0017] 1. Through the structural design of the first electric linear module, the material supporting plate and the pushing plate, during use, the material supporting plate in the material frame is driven by a pair of first electric linear modules to move up to a proper height, and then the pushing plate is driven by a pair of second electric linear modules to move horizontally, so that the pushing plate pushes the materials higher than the top of the material frame to move horizontally, thereby enabling continuous automatic feeding, avoiding workers taking materials one by one, reducing the physical consumption of workers, reducing operation steps, effectively improving the feeding speed, and ensuring the printing efficiency of the printer.

[0018] 2. Through the structural design of the limit guiding component, after the material is horizontally pushed into the space between a pair of limit guiding components, the two sides of the material exert extrusion forces on a pair of arc-shaped guiding plates, causing the movable collar to slide on the fixed rod and compress the spring. The spring contracts under the force, causing the pair of arc-shaped guiding plates to move towards each other, enabling the material to enter between the pair of limit guiding components in a flush manner. Thus, it can effectively guide and calibrate the horizontal movement angle of the material, ensuring that the material can enter the printing platform of the printer in a flush manner for printing, effectively reducing the defect rate of printed products, and ensuring the quality of printed products.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Refer to Figures 1-4, A feeding device for a UV printer, comprising a mounting frame 1, in which a material frame 2 is embedded. At the four corners of the bottom end face of the mounting frame 1, there are cushion blocks 101 provided, and at the bottom of the cushion blocks 101, there are rubber anti-slip gaskets, which can make the device be stably placed. On the mounting frame 1, there is a roller conveyor belt 9, which can quickly convey materials. One end of the roller conveyor belt 9 is connected to the material frame 2. The top of the material frame 2 and the roller conveyor belt 9 are in the same horizontal plane, and the heights of the material frame 2 and the roller conveyor belt 9 are the same, which is convenient for the conveyance of materials. In the middle of the top end face of the mounting frame 1, there is a square groove opened, and the material frame 2 is in interference fit in the square groove. On the material frame 2, there is a pair of assembly plates, and on the assembly plates, there are assembly holes, which are convenient for connecting this device to the printer.

[0026] On both side walls inside the material frame 2, there are first electric linear modules 3 embedded. Inside the material frame 2, there is a material supporting plate 4 in sliding fit. At both ends of the material supporting plate 4, there are fixed frames 401 provided. On a pair of fixed frames 401, there are a pair of sliders 402 provided.

On both side walls inside the material frame 2, there are placing grooves opened, and the first electric linear modules 3 are installed in the placing grooves. Both sides of the material supporting plate 4 are respectively connected to the sliding parts of a pair of first electric linear modules 3.

[0027] On the mounting frame 1, there are a pair of second electric linear modules 5 provided. The material frame 2 is located between the pair of second electric linear modules 5. At the bottom of the second electric linear modules 5, there are fixed platforms, and the bottoms of the fixed platforms are connected to the surface of the mounting frame 1. Between the sliding parts of the pair of second electric linear modules 5, a connecting cross plate 6 is horizontally installed. At the middle of the connecting cross plate 6, there is a pushing plate 7 provided. The bottom of the pushing plate 7 is in contact with the top surface of the material frame 2. At the bottom end of the pushing plate 7, there is an elastic rubber pad, which can be in contact with the top surface of the material frame 2 and is convenient for the pushing plate 7 to move and for the materials to move horizontally. The bottom of the elastic rubber pad is in contact with the top surface of the material frame 2. On the pushing plate 7, there is a connecting rod 701 installed, and the top end of the connecting rod 701 is connected to the middle of the connecting cross plate 6.

[0028] When this device is in use, first install this device at a suitable position on the printer through a pair of mounting plates on one side of the mounting frame 1. Then, neatly lay multiple pieces of materials flat on the material support plate 4 inside the material frame 2. Next, synchronously start a pair of first electric linear modules 3. Drive the material support plate 4 inside the material frame 2 to move up to a suitable height through the sliding parts of the pair of first electric linear modules 3, so that the topmost piece of material among the multiple pieces of materials stacked on the material support plate 4 moves up until the height exceeding the top of the material frame 2 is consistent with the thickness of a single piece of material. Then, stop the pair of first electric linear modules 3. Then, synchronously start a pair of second electric linear modules 5. Drive the connecting cross plate 6 to move horizontally through the sliding parts of the pair of second electric linear modules 5, so that the pushing plate 7 at the bottom of the connecting cross plate 6 pushes the piece of material that is higher than the top of the material frame 2 to move horizontally, horizontally push the material to be printed through between a pair of limit guiding components 8, and then enter the roller conveyor belt 9 and be conveyed by the roller conveyor belt 9 to the feeding port or the printing platform on the printer. Thus, continuous automatic feeding can be achieved, avoiding workers taking materials one by one, reducing the physical consumption of workers, reducing operation steps, effectively improving the feeding speed, and ensuring the printing efficiency of the printer.

[0029] A pair of mounting grooves are formed in the roller conveyor belt 9, and a pair of limit guiding components 8 are arranged in each of the pair of mounting grooves.

[0030] The limit guiding component 8 includes an arc-shaped guiding plate 801 and a fixing block 802. A fixing rod 803 is arranged inside the fixing block 802. A spring 804 and a movable collar 805 are in clearance fit with the outer surface of the fixing rod 803. The movable collar 805 is located at one end of the fixing rod 803. The bottom of the arc-shaped guiding plate 801 is connected to the movable collar 805. A guiding groove 8011 is formed in the arc-shaped guiding plate 801, which can limit and guide the material. A receiving seat 8012 is arranged at the bottom of the arc-shaped guiding plate 801. The bottom end of the receiving seat 8012 is connected to the movable collar 805, and the receiving seat 8012 is matched with the inner wall of the arc-shaped guiding plate 801.

[0031] When the material to be printed is horizontally pushed by the pusher plate 7 into the space between a pair of limit guiding components 8, the two sides of the material slide into a pair of guiding grooves 8011, generating a horizontal extrusion force on a pair of arc-shaped guiding plates 801. The arc-shaped guiding plates 801 transfer the extrusion force to the movable collar 805 through the receiving seat 8012. After the movable collar 805 receives the extrusion force, it slides on the outer surface of the fixed rod 803 and squeezes the spring 804 sleeved on the surface of the fixed rod 803. The spring 804 contracts under the force. The receiving seat 8012 slides in the arc-shaped guiding plate 801, causing the pair of arc-shaped guiding plates 801 to move towards each other, so that the material can enter the space between the pair of limit guiding components 8 in a flush manner. Then, after passing through the action of the pair of limit guiding components 8, the material is pushed onto the roller conveyor belt 9 in a flush manner, thereby effectively guiding and calibrating the horizontal movement angle of the material, ensuring that the material can enter the printing platform of the printer in a flush manner for printing, effectively reducing the defective rate of the printed products, and guaranteeing the quality of the printed products.
