[0045] See also Figures 1 to 5 This embodiment provides a mesh board storage machine and a mesh board storage shelf 2 balancing device applied to the mesh board storage machine.

[0046] like Figure 1As shown, the screen storage device comprises a frame 1 and a balancing device for screen storage shelves 2 mounted on the frame 1. The frame 1 is a cubical frame, with rollers 11 positioned at each of the four corners of the bottom. During use, the printing screen storage device is located at the end of the printing track. This allows the screen printing machine to directly remove and transfer the screens to the storage device. The rollers 11 at the bottom of the frame 1 facilitate movement of the storage device, allowing it to be pushed away from the printing track when screen replacement is not required.

[0047] The screen storage rack 2 balancing device includes multiple storage racks 2, a lifting chain 313, an annular slide rail 32 and a multi-link assembly 33. The screen storage machine is used to store screens used for fabric printing (i.e., printing screens). When printing fabric, the fabric is spread flat on a tabletop. Tracks and a screen printing machine are provided along the length of the tabletop. After screens with different floral patterns are installed on the screen printing machine, the screen printing machine can be controlled to move on the track and print patterns on different positions of the fabric. When another floral pattern needs to be printed, the screen on the screen printing machine needs to be removed and a screen with another floral pattern needs to be installed. The screen storage machine provided in this embodiment is used to store the above-mentioned screens.

[0048] like Figures 1 to 5 As shown, in this embodiment, the balancing device of the screen storage rack 2 includes: multiple storage racks 2, lifting chains 313, annular slide rails 32 and a multi-link assembly 33. Among them, the storage rack 2 is provided with a screen card slot 21 for storing the above-mentioned screen (i.e., printing screen), the lifting chain 313 is used to drive the storage rack 2 to cyclically lift on the rack 1, and the annular slide rails 32 and the multi-link assembly 33 are used to cooperate with the lifting chain 313 to lift the storage rack 2 so that the storage rack 2 always remains in a horizontal state during the lifting process, so that the screen can be stored in a balanced manner on the storage rack 2 and accurately aligned with the screen printing machine for screen replacement.

[0049] like Figure 1 and Figure 2 As shown, the grid layer is arranged in a ring on the rack 1. Figure 2 When the mesh plate shelf on the left side rises, the mesh plate shelf on the right side will fall accordingly, thus realizing a circular lifting operation. Figure 4 As shown, the storage shelf 2 includes two relatively arranged connecting arms 22 and a bottom connecting rod 23. The two connecting arms 22 and the bottom connecting rod 23 form a U-shaped structure. The inner sides of the connecting arms 22 are respectively provided with mesh plate slots 21 for clamping the mesh plates; and a hinge shaft 24 is provided in the middle of the outer side of the connecting arm 22.

[0050] The lifting chain 313 is an endless chain and is meshed with the two sprockets 312 to drive the storage shelf 2 to lift in the vertical direction. The lifting chain 313 is connected to a driving device 31, which includes a driving motor 311 and a sprocket 312.

[0051] The annular slide rail 32 is arranged on the outer periphery of the lifting chain 313 and is eccentrically arranged with respect to the lifting chain 313 in the vertical direction. Figure 4 As shown, the entire lifting chain 313 is located on the inner side of the annular slide rail 32, and the lifting chain 313 is biased to the left side of the annular slide rail 32. The multi-link assembly 33 is used to connect the storage shelf 2 with the lifting chain 313 and the annular slide rail 32, so that the storage shelf 2 remains horizontal during lifting; the multi-link assembly 33 includes a first link 331, a second link 332 and a third link 333, wherein one end of the first link 331 and the second link 332 are both hinged to the hinge shaft 24, and the other ends of the first link 331 and the second link 332 are respectively connected to different positions in the length direction of the lifting chain 313, the hinge shaft 24 and the other ends of the first link 331 and the second link 332 are located at three corners of a triangle, one end of the third link 333 is hinged to the hinge shaft 24, and the other end of the third link 333 is connected to the annular slide rail 32. As shown Figure 4 and Figure 5 As shown, the lengths of the first link 331 and the second link 332 are equal, and the lengths are greater than the spacing between the first link 331 and the second link 332 on the lifting chain. Figure 5 In L1, the distance between the first link 331 and the second link 332 on the lifting chain is Figure 5 In L2, L1 is greater than L2.

[0053] The lifting chain 313 is engaged with the sprocket 312, and the driving motor 311 drives the sprocket 312 to rotate, thereby driving the lifting chain 313 to rotate through the sprocket 312. The lifting chain 313 drives the mesh plate rack to lift through the first connecting rod 331 and the second connecting rod 332. The third connecting rod 333 is connected to the annular slide rail 32, so that the mesh plate rack is lifted along the annular slide rail 32 and the mesh plate rack is always kept horizontal during the lifting process. Figure 2 As shown, when the mesh panel shelves are lifted to the top and bottom of the circular track, the mesh panel shelves can still remain horizontal.

[0054] In this embodiment, the storage shelf 2 is connected to the lifting chain 313 through the first link 331 and the second link 332, and is connected to the annular slide rail 32 through the third link 333. The hinge shaft 24 and the other end of the first link 331 and the second link 332 are located at the three corners of the triangle, thereby forming a triangular stable structure, and in conjunction with the third link 333, the storage shelf 2 can always remain in a horizontal state during the lifting process, thereby improving the stability of the lifting of the storage shelf 2.

[0055] like Figure 1 、 Figure 2 and Figure 3 As shown, the annular slide rail 32 is an elliptical slide rail, comprising two vertically parallel linear slide rails and two arcuate slide rails connecting the ends of the two linear slide rails. The lifting chain 313, sprocket 312, annular slide rail 32, and multi-link assembly 33 are symmetrically arranged in two sets on either side of the width of the frame 1, and are used to control the synchronous lifting of the mesh panel shelves on the corresponding side.

[0056] The two sprockets 312 on the same side of the storage shelf 2 are driving wheels, and are both provided with a driving motor 311. The two sprockets 312 on the other side of the storage shelf 2 are driven wheels, and are both connected to the corresponding driving wheels through a transmission rod.

[0057] like Figure 4 As shown, the other end of the third connecting rod 333 is provided with a ball bearing 335, and the side of the annular slide rail 32 close to the storage shelf 2 is provided with a U-shaped groove, and the ball bearing 335 is rotatably arranged in the U-shaped groove.

[0058] like Figure 4 As shown, one end of the first link 331, the second link 332 and the third link 333 are stacked on the hinge shaft 24; a connecting piece 3131 is provided on the side of the lifting chain 313 close to the annular slide rail 32, and the other ends of the first link 331 and the second link 332 are provided with connecting blocks 334 of different thicknesses, and are respectively connected to the connecting piece 3131 through the corresponding connecting blocks 334.
