[0002] After the chain is produced, it needs to be tensioned in the initial state through positioning and tensioning equipment. The existing fixed-length tensioning device is prone to shaking between the chain and the tensioning device during use. In addition, when the chain is tensioned in the later stage, the existing equipment cannot quickly adjust the tensioning length.

[0003] According to the patent document with the existing publication number CN114104617B, a fixed-length limit tensioning device for industrial chain processing and manufacturing is disclosed, which includes a base plate, a mounting plate is fixedly connected to the top of the base plate, a fixed-length component is provided on the mounting plate, and the fixed-length component is used for automatic circulation and fixed length of the chain, the cross slide is opened on the mounting plate, the cross slide includes a transverse groove and a vertical groove, a first slider is slidably connected in the vertical groove, a first tensioning wheel is rotatably connected to the first slider, two second sliders are slidably connected in the transverse groove, and the two second sliders are relative to the first A slider is symmetrically arranged, and both of the second sliders are rotatably connected to fixed-length gears. When this technical solution is in use, after the chain completes the movement, the friction block will immediately move to the right to a position that is closely fitted with the friction wheel under the elastic force of the second spring. The friction block will again limit the rotation of the friction wheel through friction, which can ensure that the traction gear does not shake, and can make the fixed length and tensioning of the chain more stable without rebound. Regarding the above technical solution, although this solution achieves no rebound, it can only complete tensioning in a single direction when tensioning the chain, which is inconvenient during use.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a chain production fixed-length tensioning device, including a base 1, a support base 2 is welded on the base 1, and a fixed groove 8 is opened on the support base 2, and a movable seat 12 is movably installed inside the fixed groove 8, and a driving motor 18 is fixedly installed on the movable seat 12 and the support base 2. A driving gear 3 is rotatably installed on the support base 2, and a driven gear 14 is rotatably installed on the movable seat 12, and the driven gear 14 and the driving gear 3 are both fixedly installed on the driving motor 18. One end of the support base 2 is fixedly installed with a displacement mechanism 9, and a movable column 10 is installed on the displacement mechanism 9, and one end of the movable column 10 is fixed on the movable seat 12, and a scale line 7 is opened on the support base 2, and the scale line 7 cooperates with the movable seat 12, and the displacement mechanism 9 is a linear reciprocating electric push rod, which pushes the movable seat 12 to move inside the fixed groove 8, and the movement completes the fixed length use of the chain.

[0022] In this embodiment, a mounting seat 4 is movably installed on the top of the support seat 2, and a lifting mechanism 5 is fixedly installed on the mounting seat 4. A fixed seat 6 is installed on the lifting mechanism 5, and the fixed seat 6 is movably installed on one side of the support seat 2. A tensioning wheel 13 is rotatably installed on the fixed seat 6, and a chain 17 is movably installed on the tensioning wheel 13. A pushing mechanism 19 is fixedly installed on the support seat 2, and one end of the pushing mechanism 19 is fixed on the mounting seat 4. A limiting seat 11 is welded on the top of the support seat 2, and a protrusion 15 is fixed on the bottom of the limiting seat 11. A groove 16 is provided on the top of the movable seat 12, and the protrusion 15 is movably installed inside the groove 16. The lifting mechanism 5 and the pushing mechanism 19 are both linear reciprocating electric push rods. The pushing mechanism 19 pushes the adjustment of the starting height of the mounting seat 4. After the initial height adjustment of the mounting seat 4 is completed, the descending distance of the tensioning wheel 13 is adjusted, thereby realizing tensioning work under different pressures.

[0023] When the device is in use, the displacement mechanism 9 is started to push the movable seat 12 to one side of the fixed seat 6, one end of the chain 17 is installed between the driving gears 3, and the driving motor 18 at the position of the driving gear 3 is started. The driving motor 18 drives the driving gear 3 to rotate to move the chain 17. After one end of the chain 17 is installed on the driven gear 14, the driving motor 18 drives the driven gear 14 to rotate. The rotation of the driven gear 14 tightens the chain between the driving gear 3 and the driven gear 14. The length of the chain 17 between the driven gear 14 and the driving gear 3 is measured by the scale line 7. When the fixed length of the chain 17 is determined, the pushing mechanism 19 is started to push the mounting seat 4 to move upward, and the installation When the seat 4 rises, the fixed seat 6 cooperates with the marking line on one side to adjust the required height. When the height adjustment of the mounting seat 4 is completed, the lifting mechanism 5 pushes the fixed seat 6 to descend and squeeze the chain 17. The tensioning wheel 13 on the fixed seat 6 pushes the chain 17 downward. When the lifting mechanism 5 is fully extended and leaked, the maximum tensioning of the chain is completed. While the tensioning wheel 13 squeezes and tensions downward, the movement of the movable seat 12 can complete the secondary tensioning, thereby meeting the tensioning requirements in different situations. When tensioning the short-distance chain 17, the movement of the movable seat 12 enables the driven gear 14 to directly complete the stretching of the chain 17 alone, thereby avoiding the special situation where the tensioning of the tensioning wheel 13 cannot be met due to short distance.
