[0022] like Figure 1As shown, the second stand 11 and the first stand 12 are respectively provided on both sides of the central stand 1, and the second stand 11 and the base 23 are fixedly connected. The height of the second stand 11 is greater than that of the first stand 12. A winding drum 13 is provided at the middle and lower position of the front end of the central stand 1. This structure will facilitate the entire webbing winding machine to realize the winding operation of the webbing through the rotation of the winding drum 13; an articulated bracket 17 is provided at the middle and lower position of the second stand 11, and the articulated bracket 17 is rotatably connected to a limiting pressure roller 18 at a position obliquely below the winding drum 13. The outer shape of the winding drum 13 is an "I"-shaped structure. When the winding drum 13 rotates, under the limiting action of the articulated bracket 17, the limiting pressure roller 18 will press and limit the winding of the webbing from the outside of the reel of the winding drum 13.
[0023] like Figure 1 and Figure 3 As shown, a second guide support rod 14 is provided below the first stand 12, which passes through the front and rear ends of the first stand 12. A limiting sleeve 16 is rotatably connected to the front end of the second guide support rod 14. A guide strip 15 is fixedly connected to the side of the limiting sleeve 16 close to the winding drum 13. A belt outlet mouth 24 is provided at the bottom of the guide strip 15. The belt outlet mouth 24 has a semi-annular structure. When the webbing is gradually wound onto the winding drum 13, under the connection between the guide strip 15 and the limiting sleeve 16, the webbing can obtain a certain guiding and limiting effect while passing through the belt outlet mouth 24. The winding of the webbing is made more precise; the bottom of the first upright frame 12 is fixedly connected with a support block 19, the inner side thread of the support block 19 is connected with a reciprocating screw rod 20 which is rotatably connected to the rear end of the driving machine chamber 21, the rear end of the reciprocating screw rod 20 is rotatably connected with a side clamping seat 22, and the side clamping seat 22 and the base 23 are fixedly connected. When the reciprocating screw rod 20 is rotated, the support block 19 can move back and forth with the first upright frame 12, and the guiding structure composed of the belt outlet mouth 24, the guide pressure strip 15 and the limiting clamping sleeve 16 will realize relative reciprocating movement, so that the webbing can be wound in an orderly manner.
[0024] like Figure 1 and Figure 2 As shown, the front and rear sets of swing rods 7 are fixedly connected together by a short connecting rod, and the rear end of the swing rod 7 located behind the central stand 1 is fixedly connected to an auxiliary bracket 9, and a counterweight 10 is fixedly installed on the outside of the long rod end of the auxiliary bracket 9. The counterweight 10 has a cylindrical structure. When the tension adjustment structure realizes rotation adjustment, the setting of the counterweight 10 mainly plays the role of counterweight balance, so that the tension adjustment structure can realize rotation more stably; the radius of the large gear 4 is larger than the radius of the small gear 5, and the large gear 4 is set between the front and rear sets of brackets 2. Under the action of gear transmission, it will be beneficial for the entire ribbon winder to realize tension adjustment operation.
[0025] Working process: The electric energy required for the start-up and operation of the mechanical equipment in the present invention is all from an external power supply, and before using the equipment, the webbing connected to the tension adjustment structure can be wound from top to bottom along the upper and lower arrangement order of the multiple guide rods provided on the first stand 12, and brought out from the inside of the belt outlet 24, so that the head end of the webbing can be firmly connected with the winding drum 13, and the output end of the winding drum 13 can be connected together through a belt component and a driving motor provided at the lower inner side of the central stand 1. When the webbing is wound up, the processed webbing is first fed into the entire device in a guided winding manner from top to bottom. Under the pressure limitation of the limiting pressure roller 18 and the auxiliary guidance of the belt outlet mouth 24, the entire webbing winder will use the winding force generated by the winding drum 13 when it is in rotation to wind up the tension-adjusted webbing. In the winding process, the main control system of the winding will monitor the speed of the winding drum 13 in time to facilitate the subsequent relative tension adjustment operation. When tension adjustment is required during the winding process, such as Figure 2 As shown, as the webbing connected with the first guide support rod 8 is gradually sent downward, under the connection and limiting action of a group of brackets 2, the automatic speed regulator 6 controlled by the winding main control system drives the small gear 5 to rotate, so that the large gear 4 can adapt to the actual rotation speed of the winding drum 13 with the first guide support rod 8 through the rotating shaft 3 and a group of swing rods 7, thereby realizing relative automatic swing adjustment, and also making the inclination height of the first guide support rod 8 relatively change, so that the entire webbing winding machine can realize automatic adjustment of the webbing tension through the inclination adjustment of the first guide support rod 8, and while adjusting the tension, the automatic speed regulator 6 can also adjust the swing speed of the swing rod 7 and the first guide support rod 8 when they swing through the transmission action of the small gear 5 on the large gear 4, so as to achieve the purpose of adapting the speed of the entire webbing winding machine during winding operation.
[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
