Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and specifically to a specially treated screen structure. Background Technology

[0002] A screen is an essential tool in screen printing, and arguably its foundation. Screens are primarily made of polyester fiber, nylon fiber, or metal mesh woven in the warp and weft directions, then stretched and fixed to a frame under tension. Besides creating the printing pattern, the screen also controls the amount of ink transmitted during printing.

[0003] However, during the printing process, the downward pressure and depth of the squeegee cause the screen to wear out severely at certain points, which limits the printing capacity. Utility Model Content

[0004] The purpose of this invention is to provide a specially treated screen structure, which aims to solve the problem that the screen is prone to severe wear at specific points due to the downward pressure and depth of the squeegee in existing printing presses, thus limiting the printing capacity.

[0005] To achieve the above objectives, this utility model provides a specially treated wire mesh structure, including a frame and a strength component; the strength component includes multiple warp threads, multiple weft threads, a mesh layer, a fixing layer, and a tension unit;

[0006] Multiple warp threads are fixedly connected to the mesh frame and located on one side of the mesh frame. Multiple weft threads are fixedly connected to the mesh frame and located on the side of the mesh frame. The mesh fabric layer is fixedly connected to the mesh frame and located on the side of the mesh frame closer to the warp threads. The fixing layer is fixedly connected to the mesh fabric layer and to the mesh frame and located on one side of the mesh fabric layer. The tension unit is disposed on one side of the warp threads.

[0007] The mesh layer includes a squeegee surface, an intermediate layer, and a printing surface. The squeegee surface is fixedly connected to the mesh frame and located on one side of the mesh frame. The intermediate layer is fixedly connected to the squeegee surface and the mesh frame, and located on one side of the mesh frame. The printing surface is fixedly connected to the intermediate layer and located on the side of the intermediate layer away from the squeegee surface.

[0008] The tension unit includes a first polymer material layer, a second polymer material layer, and two tension mechanisms. The first polymer material layer is fixedly connected to the screen frame and is located on the side of the screen frame near the squeegee surface. The second polymer material layer is fixedly connected to the screen frame and is located on the side of the screen frame near the printing surface. The two tension mechanisms are respectively disposed on the sides of the first polymer material layer and the second polymer material layer.

[0009] The first polymer material layer has an opening pattern, which is located on the top of the polymer material layer.

[0010] The tension mechanism includes a raised layer and a recessed layer. The raised layer is fixedly connected to the first polymer material layer and is located on the side of the first polymer material layer near the doctor blade surface. The recessed layer is fixedly connected to the second polymer material layer and is located on the side of the second polymer material layer near the printing surface.

[0011] This invention discloses a special screen mesh structure. Multiple warp and weft threads are interwoven into a mesh within a frame, and the mesh is wrapped by a fabric layer. A fixing layer secures the fabric layer to the frame, and a tension unit increases the tension of the mesh, thus assembling the screen mesh for the printing press. The tension unit, in conjunction with the warp and weft threads, enhances the strength of the screen mesh and extends its service life. The assembled mesh is then placed into the printing press and fixed. Upon starting the press, the squeegee scrapes against the tension mechanism, protecting the mesh through the tension unit. This solves the problem in existing printing presses where the squeegee's downward pressure and depth cause severe wear at specific points on the screen, limiting printing capacity.

[0020] This utility model discloses a special screen printing structure, including a frame 101 and a strength component 102. The strength component 102 includes multiple warp threads 103, multiple weft threads 104, a mesh layer 105, a fixing layer 106, and a tension unit 107. The mesh layer 105 includes a squeegee surface 108, an intermediate layer 109, and a printing surface 110. The tension unit 107 includes a first polymer material layer 111, a second polymer material layer 112, and two tension mechanisms 113. The first polymer material layer 111 has an opening pattern 114, and the tension mechanism 113 includes a raised layer 115 and a recessed layer 116. The aforementioned solution solves the problem that existing printing presses suffer from severe wear at specific points on the screen due to the downward pressure and depth of the squeegee, which limits the printing capacity.

[0021] In this specific embodiment, multiple warp threads 103 are fixedly connected to the mesh frame 101 and located on one side of the mesh frame 101, multiple weft threads 104 are fixedly connected to the mesh frame 101 and located on the side of the mesh frame 101, the mesh fabric layer 105 is fixedly connected to the mesh frame 101 and located on the side of the mesh frame 101 near the warp threads 103, the fixing layer 106 is fixedly connected to the mesh fabric layer 105 and the mesh frame 101, and located on one side of the mesh fabric layer 105, and the tension unit 107 is disposed on one side of the warp threads 103. A mesh is formed by interlacing multiple warp threads 103 and weft threads 104 within the mesh frame 101, and the mesh fabric... Layer 105 wraps the mesh, and the fixing layer 106 fixes the mesh layer 105 to the frame 101. The tension unit 107 increases the tension of the mesh, thus completing the assembly of the printing press screen. The tension unit 107, together with the mesh composed of the warp threads 103 and the weft threads 104, can improve the strength of the screen and extend its service life. At this time, the assembled screen is placed into the printing press for fixation. By starting the printing press, the squeegee of the printing press scrapes on the tension mechanism 113, which can protect the mesh through the tension unit 107. This solves the problem that the screen is prone to severe wear at specific points due to the downward pressure and depth of the squeegee in existing printing presses, which limits the printing capacity.

[0022] The squeegee surface 108 is fixedly connected to the screen frame 101 and located on one side of the screen frame 101. The intermediate layer 109 is fixedly connected to the squeegee surface 108 and the screen frame 101 and located on one side of the screen frame 101. The printing surface 110 is fixedly connected to the intermediate layer 109 and located on the side of the intermediate layer 109 away from the squeegee surface 108. After the screen is placed into the printing machine, the printing squeegee of the printing machine slides on the tension unit 107, so that the ink passes through the tension unit 107 and enters the squeegee surface 108, and then passes through the squeegee surface 108 and enters the printing surface 110, and prints the object from the printing surface 110. The tension unit 107 can protect the squeegee surface 108 and prevent it from being severely worn.

[0023] Secondly, the first polymer material layer 111 is fixedly connected to the frame 101 and located on the side of the frame 101 near the squeegee surface 108. The second polymer material layer 112 is fixedly connected to the frame 101 and located on the side of the frame 101 near the printing surface 110. The two tension mechanisms 113 are respectively disposed on the sides of the first polymer material layer 111 and the second polymer material layer 112. The first polymer material layer 111 and the second polymer material layer 112 completely wrap the mesh layer 105, and the tension mechanism 113 is disposed in the gap of wrapping the mesh layer 105 to improve the strength of the mesh woven by the warp threads 103 and the weft threads 104 and the mesh layer 105.

[0024] Furthermore, the opening pattern 114 is disposed on the top of the polymer material layer. The opening pattern 114 is etched on the first polymer material layer 111 by laser etching, and the mesh woven by the warp 103 and the weft 104 is displayed through the opening pattern 114.

[0025] In addition, the raised layer 115 is fixedly connected to the first polymer material layer 111 and is located on the side of the first polymer material layer close to the squeegee surface 108. The recessed layer 116 is fixedly connected to the second polymer material layer 112 and is located on the side of the second polymer material layer 112 close to the printing surface 110. Through the staggered arrangement of the raised layer 115 and the recessed layer 116, together with the first polymer material layer 111 and the second polymer material layer 112, the overall strength of the mesh layer 105 and the mesh can be improved, and severe wear can be avoided during use.

[0026] This utility model discloses a special processed wire mesh structure. Multiple warp threads 103 and weft threads 104 are interwoven vertically within a frame 101 to form a wire mesh, which is then wrapped by a mesh fabric layer 105. Simultaneously, a fixing layer 106 secures the mesh fabric layer 105 to the frame 101. A first polymer material layer 111 and a second polymer material layer 112 completely wrap the mesh fabric layer 105. Raised layers 115 and recessed layers 116 are provided in the gaps surrounding the mesh fabric layer 105. The staggered arrangement of the raised layers 115 and recessed layers 116, combined with the first polymer material layer 111 and the second polymer material layer 112, further enhances the mesh structure. Layer 112 can improve the overall strength of the mesh layer 105 and the wire mesh, preventing severe wear during use. After the screen is placed into the printing press, the printing squeegee of the printing press slides on the tension unit 107, allowing ink to pass through the tension unit 107 into the squeegee surface 108, and then through the squeegee surface 108 into the printing surface 110, where it prints onto the object. The tension unit 107 can protect the squeegee surface 108, preventing severe wear, thus solving the problem that existing printing presses are prone to severe wear at specific points due to the downward pressure and depth of the squeegee, which limits the printing capacity.
