Description

Technical Field

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

[0002] During the fabric printing process, printing screens with different patterns are required to print different graphics on the fabric, and the printing screen storage device is used to store these printing screens. In the prior art, in order to enable the printing screen storage device to store more screens and facilitate the replacement of different screens during printing, many printing screen storage devices are designed as three-dimensional storage structures, which drive the screen basket to circulate and rise and fall in the vertical direction through a chain or pulley, thereby realizing the replacement and storage of the screen. During the screen replacement process, the screen basket is required to be able to align with the screen removal position of the screen printing machine on the printing track, so that the screen removed by the screen printing machine can accurately enter the screen basket. However, although the existing printing screen storage device can realize cyclic lifting in the vertical direction, it does not have an accurate height control system. Therefore, it is difficult to accurately control the height position of each screen basket, and it is impossible to accurately align the screen removal position of the screen printing machine, which is prone to malfunctions such as automatic screen replacement card.

[0007] The lifting device includes a driving device, an annular slide rail and a multi-link balancing mechanism; the driving device includes a driving sprocket and a lifting chain; the mesh basket is connected to the lifting chain and the annular slide rail through the multi-link balancing mechanism, and the driving sprocket is used to drive the lifting chain to operate, so that the mesh basket is cyclically lifted in a vertical direction on the frame along the annular slide rail;

[0008] The lifting chain includes a plurality of chain plates arranged relatively to each other and a pin shaft hingedly connecting two adjacent chain plates, wherein the spacing between two adjacent pin shafts is equal to the spacing between two adjacent mesh plate slots in the mesh plate lifting basket, so that when the lifting chain runs a distance corresponding to one chain plate, the mesh plate lifting basket lifts one mesh plate locking position.

[0009] Furthermore, the multi-link balancing mechanism includes a first link, a second link and a third link, one end of the first link, the second link and the third link are hinged at the same position in the middle of the side of the mesh basket, and the other ends of the first link and the second link are respectively connected to different positions in the length direction of the lifting chain; the other end of the third link is slidably connected to the annular slide rail.

[0010] Furthermore, a hinge shaft is provided in the middle of the side of the mesh basket, and one end of the first connecting rod, the second connecting rod and the third connecting rod are hinged to the hinge shaft.

[0011] Furthermore, the frame is a cubic frame, and rollers are respectively provided at the four corners of the bottom of the frame.

[0012] Furthermore, the driving device includes two driving sprockets, which are located at both ends of the lifting chain; each driving sprocket is provided with a driving motor.

[0013] Furthermore, the driving motor is a servo motor.

[0014] Furthermore, the annular slide rail includes two linear slide rails arranged in parallel along the vertical direction, and two arc slide rails connecting the ends of the two linear slide rails.

[0015] Furthermore, the printing screen storage device is arranged at the end of the printing track.

[0016] Different from the prior art, the above-mentioned printing screen storage device includes multiple screen lifting baskets and lifting devices, wherein the lifting device includes a driving device, an annular slide rail and a multi-link balancing mechanism. The screen lifting basket is connected to the lifting chain and the annular slide rail through the multi-link balancing mechanism, so that the screen lifting basket can always be stably kept horizontal during the lifting process, and the spacing between two adjacent pins of the lifting chain is equal to the spacing between two adjacent screen card slots in the screen lifting basket, so that when the lifting chain runs the corresponding distance of one chain plate, the screen lifting basket lifts one screen card to the connection position. Therefore, by setting the multi-link balancing mechanism and controlling the spacing between the pins and the screen card slots to be equal, the vertical lifting movement accuracy of the screen lifting basket can be more accurately controlled, so that the screen card slots on the screen lifting basket can be more accurately aligned with the screen removal position of the screen printing machine, so that the screen can be more smoothly moved into the printing screen storage device.

[0041] See also Figures 1 to 5, this embodiment provides a printing screen storage device. The printing screen storage device is used to store the screens (i.e., printing screens) used when printing fabrics. When printing fabrics, the fabric is spread flat on a tabletop, and a track and a screen printing machine are provided in the longitudinal direction of the tabletop. After screens with different flower 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 flower pattern needs to be printed, the screen on the screen printing machine needs to be removed and a screen with another flower pattern needs to be installed. The printing screen storage device provided in this embodiment is used to store the above-mentioned screens. In the related art, in order to enable the printing screen storage device to store more screens and improve its screen storage efficiency, a liftable three-dimensional storage structure is provided on the printing screen storage device. However, the above-mentioned three-dimensional storage structure cannot accurately control the height position of each screen basket, and it is easy to cause problems such as jamming when replacing the screen.

[0042] Based on these problems, this embodiment proposes a printing screen storage device with higher improvement accuracy and more stable operation.

[0043] like Figure 1 As shown, the printing screen storage device in this embodiment includes: a frame 1, a plurality of screen baskets 2 and a lifting device 3. Among them, the screen basket 2 is used to load the screen, and the frame 1 is used to install the screen basket 2 and the lifting device 3. The frame 1 is a cubic frame, and rollers 11 are respectively provided at the four corners of the bottom of the frame 1. When in use, the printing screen storage device is arranged at the end of the printing track. Therefore, the screen printing machine can directly disassemble the screen and transfer it to the printing screen storage device. The rollers 11 at the bottom of the frame 1 can facilitate the movement of the printing screen storage device, and when the screen does not need to be replaced, the printing screen storage device can be pushed away from the printing track.

[0044] The lifting device 3 is used to drive the mesh basket 2 to circulate and lift in the vertical and horizontal directions of the frame 1. Figure 2 As shown, the mesh basket 2 is arranged in a ring on the frame 1. Figure 2 When the mesh plate basket 2 on the left side rises, the mesh plate basket 2 on the right side falls accordingly, thereby realizing a cyclic lifting operation.

[0045] like Figure 1 As shown, multiple mesh baskets 2 are arranged in pairs on the frame 1 along the horizontal direction, and each mesh basket 2 is provided with two or more mesh card slots 21 for clamping the mesh frame. Among them, two mesh baskets 2 at the same level cooperate to load a mesh, such as Figure 1In the figure, two mesh baskets 2 at the same horizontal height are symmetrically arranged along the width direction of the frame 1, and the borders on both sides of the mesh width direction are respectively connected to the mesh card slots 21 on the mesh baskets 2 on the corresponding sides, so that the mesh is placed on the mesh baskets 2.

[0046] like Figure 1 As shown, the lifting device 3 includes a driving device 31, an annular slide rail 32 and a multi-link balancing mechanism 33; Figure 2 As shown, the driving device 31 includes a driving motor 311, a driving sprocket 312 and a lifting chain 313. The mesh basket 2 is connected to the lifting chain 313 and the annular slide 32 through the multi-link balancing mechanism 33. The driving sprocket 312 is used to drive the lifting chain 313 to operate, so that the mesh basket 2 is cyclically lifted along the annular slide 32 in the vertical direction on the frame 1. The annular slide 32 is an elliptical slide, including two linear slides arranged in parallel in the vertical direction, and two arc slides connecting the ends of the two linear slides. The lifting device 3 and the driving device 31 are both symmetrically arranged in two sets on both sides of the width direction of the frame 1, and are respectively used to control the synchronous lifting of the mesh basket 2 on the corresponding side.

[0047] like Figure 4 and Figure 5 As shown, the lifting chain 313 includes a plurality of chain plates 3132 arranged relatively to each other and a pin 3133 that hinges two adjacent chain plates 3132. The spacing between two adjacent pins 3133 is equal to the spacing between two adjacent mesh plate slots 21 in the mesh plate lifting basket 2. Figure 5 h1 and h2 are equal, wherein h1 is the distance between two adjacent mesh plate slots 21, and h2 is the distance between two adjacent pin shafts 3133, so that when the lifting chain 313 runs the corresponding distance of one chain plate 3132, the mesh plate lifting basket 2 lifts one mesh plate engagement position.

[0048] like Figure 2 and Figure 3As shown, the multi-link balancing mechanism 33 includes a first link 331, a second link 332 and a third link 333. One end of the first link 331, the second link 332 and the third link 333 are hinged at the same position in the middle of the side of the mesh basket 2, 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 other end of the third link 333 is slidably connected to the annular slide rail 32. The lifting chain 313 is engaged with the driving sprocket 312, and the driving motor 311 drives the driving sprocket 312 to rotate, thereby driving the lifting chain 313 to rotate through the driving sprocket 312. The lifting chain 313 drives the mesh basket 2 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 basket 2 is lifted along the annular slide rail 32. The first connecting rod 331, the second connecting rod 332 and the third connecting rod 333 form a balanced structure, so that the mesh basket 2 always remains horizontal during the lifting process. Figure 2 and Figure 4 As shown, when the mesh basket 2 is lifted to the top and bottom of the circular track, the mesh basket 2 can still remain horizontal. Figure 5 As shown, in order to facilitate the connection between the first link and the second link and the lifting chain 313 , a connecting piece 3131 is provided on the outside of the lifting chain 313 , and one end of the first link 331 and the second link 332 are connected to the connecting piece 3131 .

[0049] In the above technical embodiment, the printing screen storage device includes multiple screen lifting baskets 2 and lifting devices 3, wherein the lifting device 3 includes a driving device 31, an annular slide rail 32 and a multi-link balancing mechanism 33. The screen lifting basket 2 is connected to the lifting chain 313 and the annular slide rail 32 through the multi-link balancing mechanism 33, so that the screen lifting basket 2 can always maintain a stable level during the lifting process, and the spacing between the two adjacent pin shafts 3133 of the lifting chain 313 is equal to the spacing between the two adjacent screen card slots 21 in the screen lifting basket 2, so that when the lifting chain 313 runs the corresponding distance of a chain plate 3132, the screen lifting basket 2 lifts one screen card connection position. Therefore, by setting the multi-link balancing mechanism 33 and the control pin shaft 3133 and the screen card slot 21 to be equal, the vertical lifting movement accuracy of the screen lifting basket 2 can be more accurately controlled, so that the screen card slot 21 on the screen lifting basket 2 can be more accurately aligned with the screen removal position of the screen printing machine, so that the screen can be moved into the printing screen storage device more smoothly.

[0050] like Figure 3As shown, in the above embodiment, one end of the first connecting rod 331, the second connecting rod 332, and the third connecting rod 333 are each hinged to the middle portion of the side of the mesh basket 2, thereby controlling the lifting and leveling of the mesh basket 2. To facilitate the hinged connection of the first connecting rod 331, the second connecting rod 332, and the third connecting rod 333 to the basket, a hinge shaft is provided in the middle portion of the side of the mesh basket 2, and one end of the first connecting rod 331, the second connecting rod 332, and the third connecting rod 333 are each hinged to the hinge shaft. Furthermore, in some embodiments, to further reduce the rotational resistance of the hinged connection between each of the above connecting rods and the mesh basket 2, a ball bearing or a bushing may be provided on the hinge shaft, and each of the above connecting rods may be connected to the ball bearing or bushing.

[0051] In the above embodiment, in order to further control the lifting accuracy of the screen basket 2, the driving motor 311 is a servo motor. Figure 2 and Figure 4 As shown, the drive device 31 includes two drive sprockets 312 located at both ends of the lifting chain 313; each drive sprocket 312 is equipped with a drive motor 311. Therefore, both ends of the lifting chain 313 can obtain driving force, which can reduce the reduction in lifting accuracy caused by local slack of the lifting chain 313. In addition, the dual drive motors 311 can improve the load capacity of the drive device 31.

[0052] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
