[0025] In existing screen printing production lines, if one piece of equipment malfunctions or other factors require shutdown, the entire production line will have to be shut down, severely impacting work efficiency.

[0026] The following is a preferred embodiment of a film storage machine for screen printing equipment provided by this utility model, which can solve the above-mentioned technical problems.

[0027] Please refer to Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of a preferred embodiment of the film storage machine for screen printing equipment according to the present invention.

[0028] In the diagram, units with similar structures are represented by the same labels.

[0029] This embodiment provides a film storage machine for screen printing equipment, which includes: a conveying platform 11, a conveying drive module 15, a film storage rack 12, and a lifting drive module 13.

[0030] The conveying platform 11 includes multiple conveying rollers that are driveably connected to the conveying drive module 15. These rollers are arranged in parallel and distributed along the conveying direction of the conveying platform 11. Please refer to... Figure 5 In this embodiment, the conveying roller includes a central rod 111 and multiple rollers 112 sleeved on the central rod 111. The multiple central rods 111 can be connected by chain drive, and one of the central rods 11 is connected to the output end of the conveying drive module 15 by chain drive.

[0031] Please refer to Figure 2 and Figure 3 The storage rack 12 includes multiple unit frames 121 and a fixed frame 122 connecting the multiple unit frames 121. The multiple unit frames 121 are vertically interspersed between multiple conveying rollers. The fixed frame 122 is connected to the output end of the lifting drive module 13. The unit frame 121 includes a fixed rod 1211 and multiple support rods 1212 arranged vertically between two fixed rods 1211. The support rods 1212 are parallel to the conveying plane of the conveying platform 11.

[0032] The support rods 1212 of multiple unit frames 121 are located at the same height plane, meaning that multiple support rods 1212 located at the same height plane can support the sheets conveyed on the conveyor platform 11. Multiple unit frames 121 can thus support multiple layers of sheets. When a screen printing device at the rear of the sheet storage machine stops, the sheet storage machine can temporarily store the sheets conveyed from the front without shutting down the entire production line, thereby improving work efficiency.

[0033] It should be noted that, depending on the needs, the conveyor platform 11 can be composed of three independently driven small conveyor platforms connected together, i.e., as follows: Figure 2 As shown. The conveyor platform 11 can also be configured as a conveyor platform entirely driven by the same drive mechanism. Alternatively, it can be retained only as needed. Figure 2 It is transported by a small conveyor platform in the middle.

[0034] The film storage machine for screen printing equipment in this embodiment also includes a fixed cover 14 disposed above the conveying platform 11. The fixed cover 14 surrounds the outer periphery of the film storage rack 12, and the lifting drive module 13 is disposed on the top of the fixed cover 14.

[0035] More specifically, the lifting drive module 13 includes a motor 131, a belt 134, a drive pulley 132, a driven pulley 133, and a lifting connecting block 135. Vertical rods 16 are provided on both sides inside the fixed cover. Two drive pulleys 132 are provided on the top of the fixed cover. Output rods are provided at both ends of the motor 131, and each output rod is connected to one drive pulley 132. It should be noted that in this embodiment, the motor 131 is connected to a transmission, and the output rods extend from both ends of the transmission.

[0036] Driven wheel 133 is rotatably mounted on vertical rod 16. Belt 134 is connected between driving wheel 132 and driven wheel 133. Lifting connecting block 135 is slidably connected to vertical rod 16 and connects belt 134 and fixed frame 122. In this way, motor 131 drives belt to rotate, thereby driving fixed frame 122 to rise and fall.

[0037] Furthermore, a top sensor 171 is provided at the upper end of the vertical rod 16, and a bottom sensor 172 is provided at the lower end of the vertical rod 16. A sensing plate 1351 for sensing by the top sensor 171 and the bottom sensor 172 is provided on one side of the lifting connecting block 135. The lifting position of the storage rack 12 is fed back by the top sensor 171 and the bottom sensor 172.

[0038] In this embodiment, a fixed frame 122 is connected to the top and bottom of the multiple unit frames 121 respectively to improve the structural stability of the multiple unit frames 121. The fixed frame 122 at the top is connected to the lifting connecting block 135.

[0039] In addition, an auxiliary connecting block 136 is slidably connected to one side of the vertical rod 16, and the fixed frame 122 at the bottom is connected to the auxiliary connecting block 136 to improve the stability of the lifting and sliding of multiple unit frames 121.

[0040] The fixing rod 1211 of the unit frame 121 can be directly fixed to the fixing frame 122 at the bottom using screws.

[0041] For other options, please refer to [link / reference]. Figure 4 Since the unit frame 121 must pass through the gaps between multiple conveyor rollers before connecting to the bottom fixed frame 122, the installation and connection of the unit frame 121 and the fixed frame 122 is relatively inconvenient. Therefore, an extension plate 19 can be provided on one side of the bottom end of the fixing rods 1211 of the two outermost unit frames 121. The extension plate 19 is vertically arranged and has a fixing post 191. The side of the bottom fixed frame 122 is provided with fixing holes 1221 for positioning and insertion with the fixing post 191.

[0042] The bottom surface of the fixing rod 1211 is provided with a threaded hole, and the bottom fixing frame 122 is provided with a through hole 1222 corresponding to the threaded hole. The screw passes through the through hole 1222 and connects with the threaded hole.

[0043] In this way, when installing and connecting the unit frame 121 and the bottom fixing frame 122, the initial connection between the unit frame 121 and the fixing frame 122 can be achieved first through the positioning and insertion of the fixing post 191 and the fixing hole 1221, and the fixing frame 122 will not fall down. Then, screws are used to pass through the through hole 1222 and fix it to the threaded hole on the bottom surface of the fixing rod 1211, making the installation operation more convenient.

[0044] Please refer to Figure 3 The sheet storage machine for screen printing equipment in this embodiment also includes a feed sensor 181, a material arrival sensor 182, and a discharge sensor 183. The feed sensor 181 and the discharge sensor 183 are respectively located at the front and rear ends of the bottom of the conveyor platform 11, and the material arrival sensor 182 is located between the feed sensor 181 and the discharge sensor 183. The feed sensor 181, material arrival sensor 182, and discharge sensor 183 can detect the input of sheet material on the conveyor platform 11, whether the sheet material is in place, and the output of sheet material. At the same time, it can also precisely control the sheet storage rack 12 to lift and lower the sheet material on the conveyor platform 11.

[0045] In this embodiment, the support rod 1212 is preferably a cylindrical rod, which facilitates the formation of a support plane by multiple support rods 1212 at the same height.

[0046] The working principle of this utility model is as follows: When the screen printing equipment at the rear of the sheet storage machine stops, the controller controls the motor 131 to work based on the sensing signals from the feed sensor 181, the arrival sensor 182, and the discharge sensor 183. The motor 131 first drives the unit frame 121 to move until the gap between two adjacent support rods 1212 corresponds to the conveying plane of the conveying platform 11, so that the sheet can be conveyed through the unit frame 121. When the sheet on the conveying platform 11 moves to a preset position inside the multiple unit frames 121, the motor 131 drives the sheet storage rack 12 to rise, thus storing a sheet on the sheet storage rack 12. By repeating the above operation, multiple layers of sheet can be stored on the sheet storage rack 12.

[0047] Similarly, when the screen printing equipment at the back end of the film storage machine is short of film, the film storage rack 12 can be gradually lowered to place the film one by one onto the upper conveyor platform 11, and the support rod 1212 will be lowered to a position where it is no longer in contact with the film, and the conveyor platform 11 can smoothly convey the film lowered by the film storage rack 12.

[0048] This completes the process of storing and releasing sheets using the sheet storage machine for screen printing equipment according to the preferred embodiment of this invention.

[0049] The sheet storage machine for screen printing equipment in this preferred embodiment uses a unit frame that is lifted and interspersed between multiple conveyor rollers. The support rods of the multiple unit frames can support the sheet material on the conveyor platform. When a screen printing machine at the rear stops, the sheet storage machine can temporarily store the sheet material conveyed from the front to the rear without stopping the entire production line, thereby improving work efficiency.

[0050] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
