[0031] Example one:
[0032] Such as Figure 1 to Figure 8 As shown, a belt-guiding belt-feeding device for pipe bundling of an automatic winder includes a frame 1. A belt-guiding frame capable of allowing the strap to penetrate is set on the frame, and the belt-guiding frame is mounted on When the bale is working, the shape is a square closed-loop structure, and the square closed-loop structure can pass through the pipe 2 wound on the reel so that the portion of the pipe to be bundled is located in the closed-loop structure.
[0033] The belt guide frame includes three belt track assemblies which are arranged on the frame and whose overall structure is L-shaped. The belt track assemblies can be used to penetrate the strapping belt. The belt track assemblies include a fixedly installed first belt track assembly. 4. The slidable second belt track assembly 3 and the slidable third belt track assembly 5; the first belt track assembly 4 is fixed on the frame 1, and the second belt track assembly 3 is set by a first sliding device In front of the first belt assembly 4, it is located at the left front of the first belt assembly 4 when the packing is finished and reset, and the third belt assembly 5 is located on the right side of the first belt assembly 4 through a second sliding device.
[0034] The first sliding device includes a sliding bracket 6 fixed on one side of the rack 1, and two sliding rails 7 for sliding the second belt assembly 3 and located between the two sliding rails 7 are installed on the sliding bracket 6 A movable connecting frame 9 that can move on the sliding rail is installed on the sliding rail. The second belt track assembly 3 is fixedly connected to the movable connecting frame 9 and the bottom of the movable connecting frame 9 is provided with the cylinder The sliding sleeve 10 connected with the shaft hole of the guide rod; the second sliding device includes a guide rail 11, a cylinder guide rod 12 and a movable frame (not marked), and the third belt assembly 3 is fixedly connected to the movable frame. The bottom of the frame is connected with the cylinder guide rod 12, and the movable frame can slide on the guide rail 11. The third belt track assembly is driven by the cylinder guide rod to slide on the guide rail.
[0035] Each of the belt track components includes a belt frame 13 in which a spring opening and closing belt member 14 is installed, and the spring opening and closing belt member 14 includes an elastically deformable baffle 15 which is blocked by The sheet 15 forms a belt path for the strap to pass through, and the baffle is connected with a spring (not marked). The spring is used to keep the baffle forming a belt. When the strap passes through the entire closed-loop structure, it can overcome the barrier when contracted by external force. The leaf spring resistance comes out.
[0036] A triangular belt track block 17 is provided at the bend of each belt track assembly, and the two ends of the belt track block 17 are connected with the spring opening and closing belt track pieces on both sides of it.
[0037] The belt guide frame also includes a belt outlet 18 for outputting the strapping in the strapping main body 21, a belt inlet 19 for allowing the strapping to be wound around and then enters, and an air cylinder opening and closing belt channel 20. The opening and closing belt track member 20 includes a large belt end 22 that penetrates the strap and a small end 23 that outputs the strap. The belt outlet 18 is connected to the interface of the end of the third belt assembly, and the belt enters The port 19 is butted with the small end 23 of the belt, and the large end 22 of the belt is butted with the interface of the end of the first belt assembly. The three belt way components all include two ends of the interface. When forming a closed-loop structure, one end of the first belt way assembly 24 is connected to the big end 22 of the belt way, and the other end interface 25 is connected to one end interface 26 of the second belt way assembly. The other end interface 27 of the belt track assembly is docked with the one end interface 28 of the third belt track assembly, and the other end interface 29 of the third belt track assembly is docked with the strap outlet 18.
[0038] The big end 22 and the small end 23 of the air cylinder opening and closing belt member 20 are the two ends of the belt, and they are formed by joining the fixed belt plate 30 and the movable belt plate 31, and the fixed belt plate is fixedly connected. On the frame, the movable belt plate is connected to the opening and closing cylinder 33 through the push rod 32, the opening and closing cylinder is fixed to the frame, and the movable belt plate is connected to the fixed belt plate by the opening and closing cylinder. A beltway with an open end and a closed middle, the fixed belt plate and the movable belt plate have the same structure, and the two are reversed joint; the fixed belt plate and the movable belt plate both include a vertical plate 34 and a bent plate 35, The vertical plate is an approximately right-angled trapezoidal structure placed in a horizontal direction, with two ends being large and one small.
[0039] The working process of the present invention: the belt guide is used in conjunction with the main body of the package, and the second belt assembly and the third belt assembly are controlled to slide through the sliding device, so that the second belt assembly passes through the annular ring of the pipe, and then the second , The third belt assembly, the first belt assembly, the cylinder opening and closing belt assembly, etc. form a square closed loop structure (as shown in Figure 2). The strap is first conveyed from the main body of the strap, and enters the third belt track assembly, the second belt track assembly, the first belt track assembly, the belt track and the belt inlet opening of the cylinder opening and closing belt piece through the belt outlet. In this way, when the main body of the bale is continuously conveying the bale belt, the belt can be sent through the belt guide frame; then when the main body of the bale body starts the bundling process, the movable belt plate opens the belt path downward under the action of the opening and closing cylinder to ensure The strapping strip comes out of the belt smoothly, and the bundle is completely tightened to complete the strapping. After the bundling is finished, the second belt track assembly and the third belt track assembly move back to their original positions under the action of the cylinder of the sliding device respectively (as shown in Figure 1) to complete a belt feeding cycle.
