Description

Technical Field

[0001] The present application relates to the technical field of printing equipment, and in particular to a screen heating device. Background Art

[0002] Screen printing refers to the use of a silk screen as a base plate, and through the photosensitive plate-making method, a screen with images and texts is made. The basic principle of printing is that the mesh holes of the image part of the screen can pass the ink, while the mesh holes of the non-image part cannot pass the ink. Screen printing consists of five major elements: screen, scraper, slurry, printing table and substrate.

[0003] The screen is composed of a screen frame, a polyester mesh, a silk screen, and a film set on the silk screen for forming a pattern. The silk screen is located at the center of the screen frame, and the polyester mesh is fixed on the screen frame and located on the side of the silk screen. The silk screen and the polyester mesh are fixed by hot melt adhesive. In the finished screen, it is usually necessary to ensure that the silk screen has a certain tension to ensure the resilience of the silk screen during the screen printing process. In the process of making the screen, a top frame device is usually required to complete the connection between the screen frame and the silk screen.

[0004] like Figure 1 As shown, the above-mentioned top frame equipment structure includes a frame 6, a mounting plate 7 is slidable in the vertical direction on the frame 6, a cylinder 8 is installed on the frame 6, the mounting plate 7 is fixed on the telescopic rod of the cylinder 8, a limiting groove 9 for placing the screen frame is opened on the mounting plate 7, and a placement groove 10 for placing the metal false frame 20 is opened at the top of the frame 6.

[0005] Before using the above-mentioned top frame equipment, the staff is required to fix the cut silk screen 40 on the polyester mesh 30 by hot melt glue, and then fix the polyester mesh 30 on the metal dummy frame 20, and keep the silk screen 40 parallel to the dummy frame 20, and the size of the dummy frame 20 must be larger than the size of the mesh frame, and then insert the metal dummy frame 20 horizontally into the placement slot 10, so that the metal dummy frame 20 is moved to the top of the mesh frame, and then the piston rod of the cylinder 8 can be extended to press the mesh frame from bottom to top against the lower surface of the polyester mesh 30, so that the polyester mesh 30 reaches a certain tension and is tightened on the dummy frame 20, and then glue is applied between the contact surface of the mesh frame and the polyester mesh 30. After the glue is cured, the polyester mesh 30 can be fixed on the mesh frame, and finally the polyester mesh 30 that exceeds the boundary of the mesh frame is cut off to complete the production of the screen. The above process is the top frame process in the screen production process.

[0006] However, in the actual processing, it was found that since there is also tension on the wire mesh 40, if the tension on the wire mesh 40 is not released, in the subsequent frame-pushing process, when the screen frame is pressed from bottom to top against the lower surface of the polyester mesh 30 by the cylinder 8, so that the polyester mesh 30 reaches a certain tension and is stretched on the dummy frame 20, the surface of the wire mesh 40 will also be subjected to a large tension, which can easily lead to rupture at the connection between the wire mesh 40 and the polyester mesh 30, thereby causing the screen to burst during the screen production process, and then causing the entire screen to be scrapped and unusable.

The four second side plates 32 are arranged on the four peripheral edges of the second top plate 31. A second clamping assembly 33 is arranged between the second side plate 32 and the second top plate 31. The second clamping assembly 33 is used to connect the second side plate 32 to the second top plate 31. At the same time, the second clamping assembly 33 is also used to connect two adjacent second side plates 32 together. When the second top plate 31 and the four second side plates 32 are combined, the second top plate 31 and the four second side plates 32 enclose an air guide cavity 34. The second through hole 311 is located on the second top plate 31. The air outlet of the hot air blower 2 can extend into the air guide cavity 34 along the second through hole 311.

[0046] Reference Figure 5 and Figure 6The second clamping assembly 33 includes a second folding plate 331 and two groups of second fastening bolts 332. In the present embodiment, the shape and installation method of the second folding plate 331 and the second fastening bolts 332 are the same as those of the first folding plate 131 and the first fastening bolts 132, that is, one end of the second folding plate 331 is attached to the side wall of the second top plate 31 and fixed by a group of second fastening bolts 332, and the other end of the second folding plate 331 is attached to the side wall of the second side plate 32 and fixed by another group of second fastening bolts 332, and the connection between the second side plate 32 and the second top plate 31 is completed in sequence, and the assembly of the air guide cover 3 can be realized.

[0047] Reference Figure 5 and Figure 6 When in use, in order to ensure the heating effect of the hot air blown by the hot air blower 2 on the screen 40, a sealing layer 5 is provided between two adjacent second side panels 32. The sealing layer 5 is used to seal the connecting gap between the two adjacent second side panels 32, thereby preventing the hot air from leaking from the connecting gap between the two adjacent second side panels 32. In this embodiment, the sealing layer 5 is preferably set to a sealing tape, which is bonded and fixed at the connection of the second side panels 32.

[0048] Reference Figure 5 and Figure 6 A third clamping assembly 4 is provided between the first top plate 11 and the second top plate 31, and the third clamping assembly 4 is used to connect the second top plate 31 with the first top plate 11. A plurality of third clamping assemblies 4 can be provided, and the plurality of third clamping assemblies 4 are evenly spaced along the circumference of the second through hole 311. The third clamping assembly 4 is composed of a locking bolt 41 and a locking nut 42, and the locking nut 42 can be threadedly connected to the locking bolt 41. When in use, the locking bolt 41 is passed through the first top plate 11 and the second top plate 31 in sequence, and then the locking nut 42 is screwed on the locking bolt 41 until the locking nut 42 abuts against the second top plate 31, so that the connection between the second top plate 31 and the first top plate 11 can be realized, and the position of the locking nut 42 on the locking bolt 41 can be adjusted as needed, thereby adjusting the distance between the second top plate 31 and the first top plate 11.

At the same time, a flexible rubber strip can be bonded and fixed at the grabbing opening 121, so that the staff can carry the support seat 1 more conveniently. In this embodiment, when the support seat 1 is horizontally placed on the polyester net 30, there is a distance between the air outlet at the lower end of the air guide cover 3 and the wire mesh 40. At this time, the hot air blown by the hot air blower 2 can flow into the installation cavity 14 through this distance and flow to the outside along the grabbing opening 121, so as to reduce the pressure change caused by the blowing in the air guide cavity 34, which can easily cause the support seat 1 to be unstable.

[0050] The implementation principle of the embodiment of the present application is as follows: when in use, the staff first puts the metal dummy frame 20 with the polyester mesh 30 and the silk screen 40 into the placement groove 10 on the top frame equipment, and then the support seat 1 can be moved to the top of the metal dummy frame 20 through the grabbing port 121, and placed on the polyester mesh 30, so that the air outlet of the air guide cover 3 is located directly above the silk screen 40, and then the hot air blower 2 can be started, so that the hot air blown out by the hot air blower 2 is used to heat the silk screen 40. During the blowing process, the air guide cover 3 is used to guide the flow of hot air, so as to ensure that the silk screen 40 is heated over a large range and evenly, so as to ensure the tension release effect of the silk screen 40, thereby reducing the risk of the silk screen 40 exploding in the subsequent top frame process. The overall use is simple and convenient, which is conducive to improving the production quality of the screen.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
