Description

Technical Field

[0001] This utility model relates to the field of belt-making machine technology, specifically a belt-threading mechanism for a belt-making machine. Background Technology

[0002] Strapping machines, also known as bundling machines, use strapping to bundle products, improving their stability during transportation and storage. Existing strapping machines are suitable for various package sizes, with adjustable height being a key feature. By raising or lowering the machine to the appropriate position based on the package size, it can strap products of different dimensions. This process requires a strapping mechanism that restricts the strap's position. During strapping, the strap is tightened, allowing it to be removed from the strapping mechanism and secured to the product. Existing strapping mechanisms typically include hinges with external pressure and torsion springs. However, repeated opening and closing of the hinges constantly compresses the pressure springs. Because the external pressure springs are relatively short, the high compression during hinge opening can cause them to break, leading to a high failure rate in strapping equipment. Utility Model Content

[0003] The purpose of this utility model is to provide a belt threading mechanism for a belt-tying machine, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the tape threading mechanism of the tape-making machine includes a tube body and a hinge assembly: The pipe body includes a first pipe side, a second pipe side, a third pipe side, and a fourth pipe side. The first pipe side and the third pipe side are connected through the second pipe side and the fourth pipe side, and two adjacent pipe sides are perpendicular to each other. The first pipe edge, the second pipe edge, and the third pipe edge are formed with a strap groove on the outside of the pipe body; A groove is provided on the outer side of the third pipe edge; The hinge assembly includes a fixed page, a movable page, and a stud, wherein the fixed page and the movable page are rotatably connected by a pin. The fixing page is fixed to the edge of the third tube by fasteners; The active page includes a front page and a back page, with the front page located on one side of the third tube edge and the back page located on one side of the threading groove; Through holes are provided on the front page, the first tube edge, and the third tube edge, and the diameter of the through hole on the first tube edge is larger than the diameter of the through holes on the front page and the third tube edge. The stud passes through through holes on the front page, the first tube edge, and the third tube edge. Nuts are threaded to both ends of the stud. The maximum outer diameter of the nut is greater than the diameter of the through hole on the front page but smaller than the diameter of the through hole on the first tube edge. A spring is fitted on the stud and is located between the two nuts.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-7 As shown, a tape threading mechanism for a tape-making machine includes a tube body 1 and a hinge assembly: The pipe body 1 includes a first pipe edge 101, a second pipe edge 102, a third pipe edge 103 and a fourth pipe edge 104. The first pipe edge 101 and the third pipe edge 103 are connected through the second pipe edge 102 and the fourth pipe edge 104, and two adjacent pipe edges are perpendicular to each other. The first pipe edge 101, the second pipe edge 102 and the third pipe edge 103 are located on the outside of the pipe body 1 and have a threading groove 2 formed thereon; A groove 15 is provided on the outer side of the third pipe edge 103; The hinge assembly includes a fixed hinge 3, a movable hinge 4, and a stud 5. The fixed hinge 3 and the movable hinge 4 are rotatably connected by a pin 6. The fixing page 3 is fixed to the third tube edge 103 by fastener 7; Activity page 4 includes a front page 401 and a back page 402. The front page 401 is located on one side of the third tube edge 103, and the back page 402 is located on one side of the threading groove 2. On the previous page 401, the first pipe edge 101 and the third pipe edge 103, through holes 8 are provided. The diameter of the through hole 8 on the first pipe edge 101 is larger than the diameter of the through hole 8 on the previous page 401 and the third pipe edge 103. The stud 5 passes through the through holes 8 on the front page 401, the first tube edge 101, and the third tube edge 103. Both ends of the stud 5 are threaded with nuts 9. The maximum outer diameter of the nuts 9 is greater than the diameter of the through hole 8 on the front page 401, but smaller than the diameter of the through hole 8 on the first tube edge 101. A spring 10 is fitted on the stud 5. The spring 10 is located between the two nuts 9. The outer diameter of the spring 10 is smaller than the diameter of the through hole 8 on the first tube edge 101, and the outer diameter of the spring 10 is larger than the diameter of the through hole 8 on the third tube edge 103.

[0020] Fastener 7 is a screw assembly that can pass through both the first tube edge 101 and the third tube edge 103, fixing the fixing page 3 to the third tube edge 103.

[0021] Each belt-pressing machine needs to be equipped with two belt-threading mechanisms. The two belt-threading mechanisms are fixed on both sides of the belt-pressing machine by aluminum alloy brackets. The belt-pressing machine has two vertically movable corner belt track groups 13, namely the right corner belt track group 13 and the left corner belt track group 13. Each corner belt track group 13 is equipped with a guide block 14. The guide block 14 can move up and down along the slide groove 15. The corner belt track group 13 can move up and down along the belt-threading groove 2.

[0022] As the guide block 14 moves up and down within the slide groove 15, the active page 4 can be flipped by the squeezing at both ends. After the active page 4 is flipped, the corner conveyor group 13 can enter the inner side of the flipped active page 4. Both corner conveyor groups 13 are pulling the same packaging tape. The packaging tape is pulled by the same tape and enters the tape insertion groove 2 from bottom to top. The tape-tying machine needs to be raised and lowered according to the packaging size, that is, the two corner conveyor groups 13 will be raised and lowered to adapt to the packaging size. When it moves to the target position, the tape-tying machine tightens the packaging tape. The packaging tape in the tape insertion groove 2 will cause the active page 4 to flip due to the tightening of the tape-tying machine, so that the packaging tape moves out of the tape insertion groove 2. After the packaging tape moves out of the tape insertion groove 2, the active page 4 will quickly return to its original position under the elastic force of the compression spring 10.

[0023] Furthermore, the top and bottom ends of the front page 401 are respectively provided with notches, and the inside of the notches is provided with a lifting piece 11. The lifting piece 11 is inclined and can facilitate the guide block 14 to lift the movable page 4, avoid the guide block 14 and the movable page 4 from abutting each other, and ensure that the movable page 4 can be accurately and stably flipped by the guide block 14.

[0024] Furthermore, the two pry bars 11 located on the same front page 401 have the same specifications. The pry bar 11 has a fixed end 1101 and a movable end 1102. The fixed end 1101 of the pry bar 11 is fixed on the front page 401. The shortest distance between the movable ends 1102 of the two pry bars 11 located on the same front page 401 is not greater than the height of the front page 401. The pry bar 11 and the front page 401 are a whole. Two slits are processed on the front page 401 using a shearing or cutting device. At this time, a non-tilted pry bar 11 is obtained. Then, the pry bar 11 is clamped by pliers or other tools to bend the pry bar 11. The pry bar 11 and the front page 401 are a whole, which can improve the stability of the pry bar 11.

[0025] Furthermore, a number of grooves 12 are provided on the outer side of the second pipe edge 102, and the corner belt assembly 13 can slide along the grooves 12 to improve the stability of the movement of the corner belt assembly 13.

[0026] Furthermore, the end of the back page 402 that is away from the front page 401 is provided with a rounded corner. When the curved corner guide group 13 moves, it can smoothly flip the back page 402 through the rounded corner on the back page 402.
