[0002] Screen printing can be divided into many types according to its layout, printing machine type, ink properties and substrate type, but it can be divided into the following types according to its printing method. Flat screen flat screen printing: Flat screen flat screen printing machine is a method of printing on a flat substrate with a flat screen plate. During printing, the printing plate is fixed and the squeegee plate moves; Flat screen curved screen printing: Flat screen curved screen printing is a method of printing on a curved substrate (such as a sphere, cylinder, cylinder, etc.) with a flat screen printing plate; Rotary screen screen printing: Rotary screen screen printing is a cylindrical screen plate with a fixed squeegee plate inside the cylinder. The cylindrical printing plate and the substrate move synchronously at the same linear speed; Indirect screen printing: For objects with complex shapes, edges and corners, and concave surfaces, indirect screen printing must be used.

[0003] Screen printing usually requires the use of a stencil. In the past, the stencil was directly inserted into the guide groove of the fixed frame, which caused greater wear. Due to the high frequency of stencil replacement, multiple insertions reduce the smoothness of the guide groove on the fixed frame. Due to long-term dry friction, metal powder is easily generated, which in turn causes metal powder to fall on the material in later production. Summary of the invention

[0004] In order to solve the above problems, the utility model proposes a screen guide groove structure to more accurately solve the above-mentioned screen printing, which usually requires a screen. In the past, the screen was directly inserted into its guide groove when inserted into the fixed frame, which caused greater wear. Due to the high frequency of screen replacement, multiple plug-ins reduce the smoothness of the guide groove on the fixed frame. Due to long-term dry friction, metal powder is easily generated, which leads to the problem of metal powder falling on the material in later production.

[0005] The utility model is realized by the following technical solutions:

[0006] The utility model proposes a mesh plate guide groove structure, comprising two fixing frames, wherein the two fixing frames are each provided with a guide groove, the guide grooves on the two fixing frames are opposite to each other, the upper and lower bottom surfaces in the guide groove are each provided with a plurality of buffer mechanisms, the buffer mechanisms on the upper and lower bottom surfaces of the guide groove are symmetrically arranged, and the buffer mechanisms comprise two fixing seats, which are fixedly connected to the fixing frames.

[0014] Beneficial effects of the utility model:

[0015] The utility model proposes a mesh plate guide groove structure, which provides a buffer mechanism, and both sides of the mesh plate are inserted into the guide grooves on the two fixing frames from one end of the fixing frame. When inserted, the edge of the mesh plate passes through between the two vertical pulleys and is affected by the friction between the mesh plate and the vertical pulleys.

The lateral pulleys block the mesh plate from the side to prevent the side of the mesh plate from contacting the side wall of the guide groove when the mesh plate enters the guide groove and moves, thereby causing wear between the mesh plate and a fixed frame. When the mesh plate contacts the lateral pulleys, the lateral pulleys rotate to perform rotation buffering and reduce wear. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1-Figure 4 The utility model proposes a mesh plate guide groove structure, including two fixing frames 1, each of which is provided with a guide groove 2, the guide grooves 2 on the two fixing frames 1 are opposite, the upper and lower bottom surfaces in the guide groove 2 are provided with a plurality of buffer mechanisms 3, the buffer mechanisms 3 on the upper bottom surface and the lower bottom surface of the guide groove 2 are symmetrically arranged, the buffer mechanism 3 includes two fixing seats 31, the two fixing seats 31 are fixedly connected to the fixing frames 1, the two fixing seats 31 are rotatably connected to the vertical pulley 32, the distance between the two fixing frames 1 matches the width of the mesh plate, and the two fixing frames 1 are used to place A screen printing screen is placed, and the screen is used to support the sheet material. Both sides of the screen are inserted into the guide grooves 2 on the two fixing frames 1 from one end of the fixing frame 1. When inserted, the edge of the screen passes between the two vertical pulleys 32, and is affected by the friction between the screen and the vertical pulley 32. The vertical pulley 32 rotates, and the sliding friction is converted into rolling friction, thereby reducing the friction between the screen and the vertical pulley 32. At the same time, since the screen is located between the two vertical pulleys 32, the screen will not contact the fixing frame 1, thereby avoiding friction between the screen and the fixing frame 1 and damaging the guide groove 2 and the screen.

[0024] In this embodiment, the outer sides of all vertical pulleys 32 are fixedly connected to the first wear-resistant sleeve 4. The surface of the first wear-resistant sleeve 4 is smooth. When the mesh plate contacts the vertical pulley 32, it contacts the first wear-resistant sleeve 4 on the outer side of the vertical pulley 32. The first wear-resistant sleeve 4 protects the vertical pulley 32. At this time, the mesh plate will only cause wear to the first wear-resistant sleeve 4, thereby extending the service life of the vertical pulley 32. At the same time, the surface of the first wear-resistant sleeve 4 is smooth, which reduces the friction coefficient, thereby reducing the wear of the first wear-resistant sleeve 4.

[0025] In this embodiment, the inner wall of the guide groove 2 is fixedly connected to multiple mounting frames 5, and the inner side of the mounting frames 5 is rotatably connected to two vertical rods 6, and a lateral pulley 7 is fixedly connected between the two vertical rods 6. The horizontal height of the lateral pulley 7 is the same as the middle horizontal height of the two vertical pulleys 32, and the lateral pulley 7 is located between the two vertical pulleys 32. The upper and lower sides of the mesh plate are in contact with the two vertical pulleys 32, and the lateral pulley 7 blocks the mesh plate from the side to prevent the side of the mesh plate from contacting the side wall of the guide groove 2 when the mesh plate enters the guide groove 2 and moves, resulting in wear between the mesh plate and the fixed frame 1. When the mesh plate contacts the lateral pulley 7, the lateral pulley 7 rotates to perform rotation buffering and reduce wear. Here, the function of the lateral pulley 7 to reduce wear is the same as that of the vertical pulley 32.

[0026] In this embodiment, the mounting frame 5 is located on one side of the buffer mechanism 3, close to the vertical side wall of the guide groove 2. The number of mounting frames 5 is the same as the number of buffer mechanisms 3. A lateral pulley 7 is installed on one side of every two vertical pulleys 32 to block from multiple points.

[0027] In the present embodiment, each lateral pulley 7 is located on one side of the vertical pulley 32, the thickness of the lateral pulley 7 is smaller than the distance between the two vertical pulleys 32, the lateral pulley 7 is located between the two vertical pulleys 32, and the distance between the lateral pulley 7 and the upper and lower vertical pulleys 32 is the same, the lateral pulley 7 extends between the two vertical pulleys 32, and the gap between the lateral pulley 7 and the vertical pulley 32 is small, which can prevent the side of the mesh plate from being stuck between the vertical pulley 32 and the lateral pulley 7 when the mesh plate passes through the mounting frame 5.

[0028] In this embodiment, the outer side of the lateral pulley 7 is fixedly connected to the second wear-resistant sleeve 8, and the surface of the second wear-resistant sleeve 8 is smooth. The second wear-resistant sleeve 8 protects the lateral pulley 7 and reduces friction and wear between the second wear-resistant sleeve 8.

[0029] In this embodiment, the upper bottom surface and the lower bottom surface of the guide groove 2 are fixedly connected to the guide blocks 9, and the guide blocks 9 are symmetrically arranged. The two guide blocks 9 have larger openings toward the opening position, and the openings gradually decrease toward the inner side of the fixed frame 1, so that the guide mesh plate is inserted between the two vertical pulleys 32. The guide blocks 9 are made of wear-resistant material.

[0030] In this embodiment, two mounting members 10 are fixedly connected to the lower surfaces of the two fixing frames 1. The mounting members 10 are located near the two ends of the lower surface of the fixing frames 1. The mounting members 10 are provided with mounting holes. Two mounting members 10 are installed under each fixing frame 1, and the mounting members 10 lift the fixing frame 1.

[0031] Working principle: the two guide blocks 9 have larger openings toward the opening position and gradually decrease toward the inner side of the fixed frame 1, guiding the mesh plate to be inserted between the two vertical pulleys 32. The edge of the mesh plate passes through between the two vertical pulleys 32 and is affected by the friction between the mesh plate and the vertical pulleys 32. The vertical pulleys 32 rotate, converting the sliding friction into rolling friction, thereby reducing the friction between the mesh plate and the vertical pulleys 32. The lateral pulley 7 blocks the mesh plate from the side and rotates to perform rotation buffering.

[0032] Of course, the present utility model may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present utility model.
