Description

Technical Field

[0001] The utility model relates to the field of flat chains, and particularly relates to an improved flat chain. Background Art

[0002] A flat chain is a special conveying device, mainly composed of a chain, a guide rail, and movable plate pieces installed in parallel. It is driven by the chain to make the plate pieces reciprocate along a straight track, so as to realize the continuous and uniform conveying of materials in the horizontal direction. Flat chains are widely used in various industrial fields, such as food and beverage, pharmaceuticals, chemicals, packaging, electronics, automotive parts, and logistics warehousing, for material conveying, picking, sorting, and assembly line operations.

[0003] In the prior art, the panel of the conveyor is usually flat, and the items are easy to roll. Therefore, the panel is usually made into a V-shaped panel to improve the stability of the items. When the material is heavy, hard, or irregular in shape, the material will impact the V-shaped panel during the conveying process, resulting in wear or deformation of the V-shaped panel. Therefore, it is necessary to replace the V-shaped panel to ensure the operation stability of the flat chain. However, in the actual use process, the V-shaped panel is often fixedly connected to the outer link plate and the inner link plate by welding or bolt connection. As a result, when the V-shaped panel is worn or damaged after long-term use, it is not convenient to disassemble and replace the V-shaped panel in time, which not only reduces the replacement efficiency of the V-shaped panel but also affects the conveying efficiency of the flat chain. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an improved flat chain, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An improved flat chain includes an outer link plate and an inner link plate. A connecting pin shaft is movably connected between the outer link plate and the inner link plate, and support rollers are movably connected to both ends of the connecting pin shaft. The top surfaces of the left and right symmetric outer link plates and inner link plates are respectively fixedly connected with a V-shaped panel through a connecting mechanism. The connecting mechanism includes an L-shaped support plate, a threaded rod, a moving plate, and a limiting plate. The top surfaces of the outer link plate and the inner link plate are respectively fixedly connected with an L-shaped support plate, and the threaded rod is movably connected inside the top surface of the L-shaped support plate through rotating rods at both ends. The moving plate is movably connected with the threaded rod through a threaded hole on the side wall and is movably connected with the L-shaped support plate through sliders on both sides, and a limiting plate is also fixedly connected to the inner side wall of the moving plate.

[0007] Preferably, a set of symmetric positioning rods are fixedly installed on both sides of the bottom surface of the V-shaped panel, and installation openings are respectively formed on both sides of the top surface of the V-shaped panel, and limiting grooves are formed on the inner side walls of the installation openings.

[0008] Preferably, L-shaped support plates are fixedly installed on the top surfaces of the outer link plate and the inner link plate, and a set of symmetric positioning grooves are formed on the top surfaces of the L-shaped support plates, and the positioning rods are inserted and installed in the positioning grooves.

[0009] Preferably, moving openings are further formed on the top surfaces of the positioning rods and located at the outer sides of the positioning grooves, and rotating holes are respectively formed on the left and right side walls of the inner parts of the moving openings, and sliding openings are respectively formed on the front and rear side walls of the inner parts of the moving openings.

[0010] Preferably, rotating rods are fixedly installed at the left and right ends of the threaded rod respectively, and the rotating rods are movably installed in the rotating holes, and a knob is further fixedly installed on the end wall of the rotating rod at the outer side end.

[0011] Preferably, a threaded hole is formed on the side wall of the moving plate, and the moving plate is in threaded connection with the threaded rod through the threaded hole. Sliding blocks are respectively fixedly installed on the front and rear side walls of the moving plate, and the sliding blocks are movably installed in the sliding openings. A limiting plate corresponding to the limiting groove is further fixedly installed on the inner side wall of the moving plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, with the connection mechanism cooperating with the use of the flat chain, when the V-shaped panel is worn or damaged and needs to be replaced, rotate the knob on the outer side wall of the L-shaped support plate below the damaged V-shaped panel. The knob will drive the threaded rod to rotate through the rotating rod, so that the moving plate moves outward in the moving opening and the installation opening along the threaded rod through the threaded hole until the limiting plate moves out of the limiting groove, and then the V-shaped panel can be disassembled. When installing, insert the positioning rod into the positioning groove for positioning, and then rotate the knob in the reverse direction to make the moving plate move inward until the limiting plate enters the limiting groove and the knob cannot be rotated, and then the disassembly and replacement of the V-shaped panel can be completed. Thus, by improving the connection method between the V-shaped panel and the outer link plate and the inner link plate through the connection mechanism, the purpose of facilitating the disassembly and replacement of the V-shaped panel can be achieved, which not only improves the replacement efficiency of the V-shaped panel, but also improves the conveying efficiency of the flat chain.

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] As Figure 1 - Figure 3 shown, an improved flat chain includes an outer link plate 1 and an inner link plate 2. A connecting pin shaft 3 is movably connected between the outer link plate 1 and the inner link plate 2, and support rollers 4 are movably connected to both ends of the connecting pin shaft 3. The top surfaces of the left and right symmetric outer link plates 1 and inner link plates 2 are respectively fixedly connected with a V-shaped panel 5 through a connection mechanism 6. The connection mechanism 6 includes an L-shaped support plate 10, a threaded rod 15, a moving plate 18 and a limit plate 21. The top surfaces of the outer link plate 1 and the inner link plate 2 are respectively fixedly connected with an L-shaped support plate 10, and the threaded rod 15 is movably connected to the inner top surface of the L-shaped support plate 10 through rotating rods 16 at both ends. The moving plate 18 is movably connected to the threaded rod 15 through a threaded hole 19 on the side wall and is movably connected to the L-shaped support plate 10 through slide blocks 20 on both sides, and a limit plate 21 is also fixedly connected to the inner side wall of the moving plate 18.

[0020] As Figure 2 shown, a set of symmetric positioning rods 7 are respectively fixedly installed on both sides of the bottom surface of the V-shaped panel 5, and installation openings 8 are respectively opened on both sides of the top surface of the V-shaped panel 5. A limit groove 9 is opened on the inner side wall of the installation opening 8. The positioning rods 7 installed on the bottom surface of the V-shaped panel 5 can be used to position and install the V-shaped panel 5. The installation openings 8 opened on the top surface of the V-shaped panel 5 can enable the moving plate 18 to move left and right inside. After the limit plate 21 is stuck in the limit groove 9 through the limit groove 9, it can play a role in limiting and fixedly installing the V-shaped panel 5;

[0021] As Figure 2 and Figure 3As shown, L-shaped support plates 10 are fixedly installed on the top surfaces of the outer link plates 1 and the inner link plates 2, and a set of symmetrical positioning grooves 11 are formed on the top surfaces of the L-shaped support plates 10. The positioning rods 7 are inserted and installed in the positioning grooves 11. The provided L-shaped support plates 10 are used to support the V-shaped panel 5, so as to facilitate the installation of the V-shaped panel 5 between the outer link plates 1 or between the inner link plates 2. Inserting the positioning rods 7 into the positioning grooves 11 can position and install the V-shaped panel 5 between the outer link plates 1 or the inner link plates 2;

[0022] As Figure 3 shown, an activity opening 12 is further formed on the top surface of the positioning rod 7 and at the outer side part of the positioning groove 11, and rotation holes 13 are respectively formed on the left and right side walls inside the activity opening 12, and sliding openings 14 are respectively formed on the front and rear side walls inside the activity opening 12. The provided activity opening 12 enables the moving plate 18 to move inside it, and the rotation holes 13 enable the rotation operation of the rotating rod 16, while the sliding openings 14 enable the sliding block 20 to slide inside it;

[0023] As Figure 3 shown, rotating rods 16 are respectively fixedly installed at the left and right ends of the threaded rod 15, and the rotating rods 16 are movably installed in the rotation holes 13. A knob 17 is further fixedly installed on the end wall of the outer-side rotating rod 16. When installing or disassembling the V-shaped panel 5, the knob 17 can be rotated. The knob 17 will drive the rotating rod 16 to rotate in the rotation hole 13, and the rotating rod 16 will drive the threaded rod 15 to rotate;

[0024] As Figure 3 shown, a threaded hole 19 is formed on the side wall of the moving plate 18, and the moving plate 18 is threadedly connected with the threaded rod 15 through the threaded hole 19. Sliding blocks 20 are respectively fixedly installed on the front and rear side walls of the moving plate 18, and the sliding blocks 20 are movably installed in the sliding openings 14. A limiting plate 21 corresponding to the limiting groove 9 is further fixedly installed on the inner side wall of the moving plate 18. Driven by the rotation of the threaded rod 15, the moving plate 18 will horizontally move along the threaded rod 15 through the threaded hole 19 on the side wall in the activity opening 12 and the installation opening 8, and the sliding blocks 20 will slide in the sliding openings 14, so that the limiting plate 21 installed on the inner side wall will move in and out of the limiting groove 9, so as to achieve the purpose of facilitating the disassembly, installation and replacement of the V-shaped panel 5.

[0025] It should be noted that the present utility model is an improved flat chain. When the V-shaped panel 5 is damaged during use and needs to be disassembled and replaced, rotate the knob 17 on the outer side wall of the L-shaped support plate 10 below the damaged V-shaped panel 5. The knob 17 will drive the rotating rod 16 to rotate within the rotating holes 13 opened on the left and right side walls inside the movable opening 12 on the top surface of the L-shaped support plate 10. The rotating rod 16 will drive the threaded rod 15 to rotate within the movable opening 12, causing the moving plate 18 to move outward along the threaded rod 15 through the threaded holes 19 opened on its side wall within the movable opening 12. Moreover, the sliders 20 installed on the front and rear sides of the moving plate 18 will slide within the sliding openings 14 opened on the front and rear side walls inside the movable opening 12. At the same time, the moving plate 18 will also move synchronously within the installation openings 8 opened on both sides of the top surface of the V-shaped panel 5, and drive the limiting plate 21 installed on its inner side wall to move from the limiting groove 9 opened on the inner side wall inside the installation opening 8 into the installation opening 8. Until the knob 17 can no longer be rotated, the damaged V-shaped panel 5 can be disassembled from the chain. Then, insert the positioning rod 7 installed on the bottom surface of the new V-shaped panel 5 into the corresponding positioning groove 11 opened on the top surface of the L-shaped support plate 10. And after the moving plate 18 and the limiting plate 21 installed on its inner side wall enter the installation opening 8, rotate the knob 17 in the reverse direction to drive the threaded rod 15 to reverse through the rotating rod 16, causing the moving plate 18 to move inward along the threaded rod 15 through the threaded holes 19 within the movable opening 12 and the installation opening 8 until the limiting plate 21 enters the limiting groove 9 and the knob 17 can no longer be rotated, then the disassembly and replacement of the V-shaped panel 5 can be completed. Thus, by improving the connection method between the V-shaped panel 5 and the outer link plate 1 and the inner link plate 2 through the connection mechanism 6, the purpose of facilitating the disassembly and replacement of the V-shaped panel 5 can be achieved, which not only improves the replacement efficiency of the V-shaped panel 5 but also improves the conveying efficiency of the flat chain.
