[0039] Please refer to Figures 1-7 The present application provides a coil conveying chain and a conveyor, comprising:

[0040] The chain body 2 comprises an inner chain plate 21, an outer chain plate 22 and a pin shaft 23, which are sequentially arranged in a closed ring shape. The inner chain plate 21 and the outer chain plate 22 each comprise a same panel 24. The panel 24 of the inner chain plate 21 is fixedly installed with two inner chain links 25 at the bottom. The panel 24 of the outer chain plate 22 is fixedly installed with two outer chain links 26 at the bottom. The adjacent portions of the inner chain plate 21 and the outer chain plate 22 are installed on the same pin shaft 23 through the inner chain links 25 and the outer chain links 26. The pin shaft 23 is installed with an installation mechanism 27 for limiting the inner chain plate 21 and the outer chain plate 22;

[0041] The rack 1 comprises two side plates 101, and an installation cavity 102 for installing the chain body 2 is formed between the two side plates 101;

[0042] The driving assembly 3 comprises a main driving mechanism 31 and a driven mechanism 32. The main driving mechanism 31 comprises a first fixed shaft 311 and a motor 313 for driving the first fixed shaft 311 to rotate. The first fixed shaft 311 is installed through a bearing at one end of the rack 1, and the surface of the first fixed shaft 311 is fixedly installed with a first ratchet wheel 312;

[0043] The driven mechanism 32 comprises a second fixed shaft 321 which is movably installed at the end of the rack 1 far from the main driving mechanism 31, and the surface of the second fixed shaft 321 is provided with a second ratchet wheel 322 through a bearing.

[0044] The teeth grooves of the first ratchet wheel 312 and the second ratchet wheel 322 are matched with the pin shaft 23 of the chain body 2.

[0045] The panel 24 comprises a bearing V-shaped part 241, the edges on both sides of the bearing V-shaped part 241 are curved to form reinforcing edges 242, and the reinforcing edges 242 are connected with the bearing V-shaped part 241 through first arc-shaped parts 243; the two ends of the panel 24 are fixedly connected with reinforcing end plates 244 through second arc-shaped parts 245, the top of the reinforcing end plate 244 is arc-shaped, and the arc-shaped edges of the reinforcing end plate 244 are fixedly connected with the bearing V-shaped part 241 and the first arc-shaped part 243 through the second arc-shaped parts 245 respectively; through the reinforcing edges 242, the reinforcing end plates 244, the first arc-shaped parts 243 and the second arc-shaped parts 245 on the panel 24, stronger load can be borne under the same thickness compared with the existing chain plate, that is, the consumption of the panel 24 can be effectively saved, the cost of the chain is reduced, and the first arc-shaped parts 243 and the second arc-shaped parts 245 are arc-shaped, so that the panel 24 between the inner chain plate 21 and the outer chain plate 22 can be conveniently machined, the end face of the chain formed thereby is on the same straight line, and paper loss caused by lateral entry and exit of the paper roll is effectively avoided.

[0046] The mounting mechanism 27 comprises rolling wheels 272 which are installed at both ends of the pin shaft 23 through elastic retaining rings 271, and limiting spacer sleeves 273 which are installed between bearings and the outer chain plate 22, the inner chain plate 21 and the outer chain plate 22, the rolling wheel 272 is a bearing which can bear radial load, so that the structure of the chain body 2 is compact.

[0047] The side plates 101 of the rack 1 are provided with upper bearing rails 4 and lower bearing rails 5, and the upper bearing rails 4 and the lower bearing rails 5 are used for bearing and guiding the rolling wheels 272 on the chain.

[0048] The side plates 101 of the rack 1 are provided with horizontal sliding holes 103, the second fixed shaft 321 is inserted and installed through the two sliding holes 103, the two ends of the second fixed shaft 321 are rectangular, and the inner walls of the top and the bottom of the sliding hole 103 are provided with reinforcing plates, one end of the rack 1 provided with the sliding hole 103 is provided with a tensioning mechanism 6, the tensioning mechanism 6 is used for adjusting the position of the second fixed shaft 321 in the sliding hole 103 and changing the tightness of the chain body 2.

[0049] The tensioning mechanism 6 comprises a connecting fixing lug 61 mounted on the rack 1, a lead screw 62 fixedly connected with the second fixing shaft 321, the lead screw 62 movably penetrating through the fixing lug 61, and a locking nut 63 for locking the relative position of the lead screw 62 and the fixing lug 61. By screwing the locking nut 63, the lead screw 62 is moved on the fixing lug 61, that is, the second fixing shaft 321 is moved in the sliding hole 103, and when the second fixing shaft 321 is moved to a suitable position, the locking nut 63 is tightened to lock the position of the second fixing shaft 321 in the sliding hole 103, thereby realizing the tensioning of the chain body 2.

[0050] The rectangular arrangement of the two ends of the second fixing shaft 321 can effectively ensure the stability of the second fixing shaft 321, avoid affecting the stability of the second fixing shaft 321 when the second ratchet wheel 322 on the second fixing shaft 321 rotates, and because the second ratchet wheel 322 is mounted on the second fixing shaft 321 through a bearing, the horizontal adjustment of the tensioning mechanism 6 can make the equipment height lower, the installation space requirement smaller, and the safety of the equipment operation improved, while reducing the outer width of the equipment within a certain range and adapting to the storage or handling of smaller diameter coils.

[0051] The arc-shaped guide rail 51 fixedly connected to one end of the driven mechanism 32 can effectively adapt to the change in the curvature of the chain body 2 between the second ratchet wheel 322 and the lower bearing rail 5 after the chain is tensioned, thereby ensuring that the rolling wheel 272 on the chain body 2 can smoothly enter the lower bearing rail 5.

[0052] The limit frame 7 is mounted on both sides of the rack 1, which can prevent the material from rolling off from the side.

[0053] Working principle:

[0054] By starting the motor 313 in the main driving mechanism 31, the first fixing shaft 311 mounted on the rack 1 through a bearing can be rotated, the first ratchet wheel 312 can be rotated by the rotation of the first fixing shaft 311, thereby driving the chain body 2 to rotate. Due to the improvement of the inner link plate 21 and the outer link plate 22 on the upper plate 24 in the chain body 2, compared with the existing chain plate under the same thickness, it can bear stronger load, that is, it can effectively save the consumption of the upper plate 24, thereby reducing the cost of the chain.

[0055] When the chain body 2 needs to be tensioned, by turning the locking nut 63, the lead screw 62 moves on the fixed lug 61, that is, the second fixed shaft 321 can be moved in the sliding hole 103, when the second fixed shaft 321 moves to the appropriate position, by tightening the locking nut 63, the position of the second fixed shaft 321 in the sliding hole 103 is locked, thereby realizing the tensioning of the chain body 2. Because the second ratchet 322 is installed on the second fixed shaft 321 through the bearing, the horizontal adjustment of the tensioning mechanism 6 has the advantages of simple structure, low cost, lower equipment height, smaller installation space requirement, improved safety of equipment operation, and reduced equipment outer width within a certain range, which is suitable for the storage or handling of smaller diameter coils.
