DETAILED DESCRIPTION OF THE INVENTION

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0018] A double-tape automatic strapping machine, as Figures 1 - 5 shown, includes a base 1, a bracket 2, a wire reel 3, a wire 4, an annular circular tube 5, a motor 6, a first gear 7, a second gear 8, a first conveying roller 9, a second conveying roller 10, and a placement table 21. The number of brackets 2 is four. The brackets 2 are provided on the top of the base 1. Two brackets 2 at the rear are rotatably connected with two wire reels 3, and the wire 4 is wound around the wire reels 3. Two brackets 2 at the front are fixedly connected with annular circular tubes 5 on the side close to each other. Grooves are opened on the opposite sides of the annular circular tubes 5. Notches are opened on the rear sides of the annular circular tubes 5. Motors 6 are installed in the middle of the two brackets 2 at the rear. First gears 7 are fixedly connected to the output shafts of the motors 6. A first conveying roller 9 and a second conveying roller 10 are rotatably connected to the side of the support of the motor 6 close to the annular circular tube 5. The second conveying rollers 10 are higher than the first conveying rollers 9. Second gears 8 are fixedly connected to the first conveying rollers 9. The first gears 7 are engaged with the corresponding second gears 8. Placement tables 21 are fixedly connected between the left side of the top of the base 1 and the two annular circular tubes 5.

[0019] When bundling an item, place the item on the placement table 21, pass the wires 4 on the two wire reels 3 through the corresponding first conveying roller 9 and the second conveying roller 10 respectively. The wire 4 contacts the first conveying roller 9 and the second conveying roller 10 at the same time, and manually guide the wire 4 to the nozzle of the annular circular tube 5. Start the motor 6 to drive the first gear 7 to rotate. The first gear 7 drives the second gear 8 to rotate. The rotation of the second gear 8 drives the first conveying roller 9 to rotate. The rotation of the first conveying roller 9 and the second conveying roller 10 pulls out the wire 4. When the wire 4 is pulled out, it drives the two wire reels 3 to rotate at the same time. After the wire 4 moves from the lower nozzle of the annular circular tube 5 along the annular circular tube 5 to the upper nozzle of the annular circular tube 5, cut the wire at the upper nozzle of the annular circular tube 5, and then tighten the two ends of the wire in the annular circular tube 5, so that the wire gradually leaves the annular circular tube 5 through the groove on the annular circular tube 5, and bundle the item to be bundled tightly. Finally, take away the item that has been bundled on the placement table 21, thus completing a bundling of the item. At the same time, using two wires 4 to bundle the item can make the bundling of the item more firm, and can also firmly bundle large items.

[0020] As Figure 1 and Figure 2As shown, it further includes a rotary clamping cylinder 13. The middle parts of the two rear brackets 2 are fixedly connected with the rotary clamping cylinder 13. When it is necessary to tighten the two ends of the iron wire 4, start the rotary clamping cylinder 13 to clamp the two ends of the iron wire 4 and rotate and tighten it, so that the iron wire 4 can leave the annular round tube 5 more quickly and closely adhere to the item to be bundled, improving the bundling efficiency of this bundling machine and making the bundling of items by this bundling machine firmer.

[0021] As Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it further includes an annular cover 12. The annular cover 12 is detachably connected to the grooves of the two annular round tubes 5.

[0022] When the iron wire 4 moves along the annular round tube 5, the annular cover 12 can block the iron wire 4 to prevent the iron wire 4 from moving out of the annular round tube 5 in advance when moving in the annular round tube 5, preventing the failure of item bundling. When it is necessary to tighten the iron wire 4, remove the annular cover 12, and the iron wire 4 can leave the annular round tube 5 and closely adhere to the item to be bundled when being tightened.

[0023] As Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it further includes a first cylinder 15, a slider 16, a first connecting rod 17, a second connecting rod 19 and a rotating plate 18. The top of the annular cover 12 is fixedly connected with the slider 16. The sliders 16 are all slidably connected to the top of the base 1. A through hole is opened in the middle of the base 1. A rotating plate 18 is rotatably connected in the through hole of the base 1. The rear side of the top of the rotating plate 18 is rotatably connected with the first connecting rod 17. The front side of the top of the rotating plate 18 is rotatably connected with the second connecting rod 19. The other end of the first connecting rod 17 is rotatably connected to the bottom of the left slider 16. The other end of the second connecting rod 19 is rotatably connected to the bottom of the right slider 16. The left side of the base 1 is fixedly connected with the first cylinder 15. The piston rod of the first cylinder 15 is fixedly connected to the left side on the left slider 16.

[0024] When it is necessary to remove the annular cover 12 to disengage the wire 4 from the annular pipe 5, the first cylinder 15 is activated. The piston rod of the first cylinder 15 retracts, driving the left slider 16 to move leftward. The leftward movement of the left slider 16 causes the right slider 16 to move rightward through the first connecting rod 17, the second connecting rod 19, and the rotating plate, thereby removing the two annular covers 12 simultaneously, enabling the wire 4 to leave the annular pipe 5 from the groove of the annular pipe 5 and closely adhere to the item to be strapped. When the wire 4 needs to move along the annular pipe 5 or when it is necessary to install the annular cover 12 back onto the annular pipe 5, the piston rod of the first cylinder 15 extends, driving the left slider 16 to move rightward. The rightward movement of the left slider 16 causes the right slider 16 to move leftward through the first connecting rod 17, the second connecting rod 19, and the rotating plate, thereby installing the two annular covers 12 back onto the annular pipe 5 simultaneously. The simultaneous installation and removal of the annular cover 12 can be achieved, improving the working efficiency of this strapping machine.

[0025] As Figures 1 - 4 shown, there are through grooves opened on the inner sides of the two rear brackets 2. Both wire reels 3 are slidably connected to the two rear brackets 2 through these through grooves. After this strapping machine has been used for a period of time, when the wires 4 on both wire reels 3 are used up, the wire reels 3 are moved upward and removed along the through grooves of the two rear brackets 2. Then, new wire reels 3 are installed in the middle of the two rear brackets 2 along the through grooves of the two rear brackets 2. After replacing the new wire reels 3, this strapping machine can continue the strapping operation. The replacement of the wire reels 3 is simple and convenient, which can improve the working efficiency of this strapping machine.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
