In the description of this application, unless otherwise expressly defined, terms such as "set," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0026] The following is combined Figures 1 to 5 The embodiments of this utility model are described below.

[0027] The first aspect of this application provides a strapping machine guide device, which includes a guide frame 100, a conveying assembly 200, and a feeding assembly 300;

[0028] The guide belt frame 100 has a guide belt channel 110;

[0029] The conveying assembly 200 includes a plurality of drive wheels 210 and a drive belt 220. The plurality of drive wheels 210 are disposed on the guide belt channel 110, and the plurality of drive belts 220 are wound between the drive wheels 210.

[0030] The belt feeding assembly 300 includes a belt guide plate 310 and an inlet plate 320. The belt guide plate 310 is fixed on the belt guide channel 110 and disposed at the exit end of the transmission belt 220. The inlet plate 320 includes an inlet portion 321 and a connecting portion 322 that are connected to each other. A belt guide gap 3211 is formed between the inlet portion 321 and the belt guide plate 310. The connecting portion 322 is movably connected to the belt guide plate 310 through an elastic member 350.

[0031] During operation, when the operator places the items to be bundled in the designated position on the workbench, the bundling machine is triggered to bundle them. The bundling strap enters through the guide channel 110 of the guide frame 100, is driven by the transmission wheel 210 to the transmission belt 220, and is output from the transmission belt 220. After passing through the guide plate 310, the bundling strap head enters the welding mechanism 400 through the guide gap 3211 formed between the guide portion 321 of the guide piece 320 and the guide plate 310. The body of the bundling strap wraps around the item once along a preset track. When the strap body contacts the guide pieces 320 on both sides, it applies a pushing force outward along the guide pieces 320. Since the connecting portion 322 of the guide piece 320 is movably connected to the guide plate 310 through the elastic member 350, the elastic member 350 is compressed under the pushing force, and the guide pieces 320 on both sides open outward to make room for the strap body to pass through. After the belt body has completely passed through, the elastic element 350 releases its elastic force, causing the guide plate 320 to reset and restore the initial belt gap state between the guide plate 320 and the guide plate 310.

[0032] Therefore, the transmission belt 220 is used to achieve stable conveying of the packing strap, and the guide plate 310 and the guide piece 320 are used to complete the guiding transition. The elastic element 350 enables the guide part 321 to have buffer adjustment capability, ensuring that the packing strap accurately enters the welding mechanism 400, improving the stability of the guide belt, effectively preventing jamming during the paper tape conveying process, ensuring the tape feeding effect, and guaranteeing the bundling quality.

[0033] In some embodiments, a connecting shaft 330 is fixed to one side of the guide plate 310, the connecting part 322 is sleeved on the connecting shaft 330, a blocking piece 340 is fixed to the outside of the connecting shaft 330, and the elastic member 350 is disposed between the connecting part 322 and the blocking piece 340. When the packing strap pushes outward to the inlet 321, the connecting part 322 compresses the spring, and after opening, the packing strap springs in, and the spring returns to reset the inlet 321.

[0034] Optionally, the elastic element 350 is a spring, with one end of the spring abutting against the connecting part 322 and the other end of the spring connected to the blocking piece 340. This allows the guide part 321 to swing flexibly, preventing the strapping from getting stuck on the guide part 321 when it falls, thus affecting the bundling effect.

[0035] In some embodiments, the guide plate 310 is provided with a plurality of spaced-apart ventilation holes 313, which are used to adsorb the packing strap onto the guide plate 310. Optionally, a fan is provided inside the guide frame 100, which, after being started, creates a negative pressure environment inside the guide frame 100 to adsorb the packing strap onto the guide plate 310 through the ventilation holes 313. Specifically, the guide plate 310 is provided with a plurality of spaced-apart ventilation holes 313, and the guide frame 100 is sealed. By providing a fan inside, after the fan is started, a negative pressure is created inside the guide frame 100. The ventilation holes 313 generate suction to press the packing strap tightly against the surface of the guide plate 230 to adsorb the packing strap, so that the strap head is conveyed along the surface of the guide plate 310 and enters the guide gap 3211, to prevent the strap head from lifting up during conveying or entering the welding process, which would affect the bundling effect.

[0036] Specifically, the guide plate 310 includes a first plate 311 and a second plate 312. The first plate 311 is horizontally disposed on the guide channel 110, and the second plate 312 is inclinedly disposed in the guide channel 110, such that the end of the second plate 312 is connected to the guide frame 100 and communicates with the guide channel 110, and one end of the second plate 312 is connected to the first plate 311, so that there is a gap between the first plate 311 and the second plate 312. The vent 313 is disposed on the first plate 311. When a negative pressure is generated in the guide channel 110, the belt head can be adsorbed on the surface of the first plate during conveying.

[0037] Furthermore, the width of the first plate 311 is greater than the width of the transmission belt 220. After the packing strap is output from the narrow transmission belt, it obtains a more stable support surface on the first plate, avoiding the curling of the strap head edge caused by the width limitation of the transmission belt, and improving the subsequent feeding accuracy.

[0038] In some embodiments, the guide surface 3212, the inlet portion, and the connecting portion are integrally formed, and the integral structure has no splicing gaps, which can improve the smoothness of the inlet.

[0039] In some embodiments, the edge of the inlet portion 321 is provided with a guide surface 3212 to prevent the packing strap from being obstructed at the edge of the inlet portion 321. Optionally, the guide surface 3212 is an inclined surface or an arc surface. When the packing strap contacts the guide surface, it is guided along the inclined surface or arc surface, further preventing jamming during the paper tape conveying process, ensuring the tape feeding effect, and guaranteeing the bundling quality.

[0040] Existing transmission belts are all installed in an alternating pattern, with multiple belts between two synchronous pulleys. Each synchronous pulley is connected in an alternating manner, and the synchronous pulleys are connected sequentially to convey the packing straps. If the belts are too narrow, the alternating installation means that if any belt breaks, the entire belt system must be disassembled and reinstalled. Therefore, in some embodiments, guide plates 230 are provided on both sides of the transmission belt 220 along the conveying direction. The guide plates 230 are fixed to the inner wall of the guide frame 100. After optimization, only one or two belts are needed, reducing assembly difficulty; when replacing the belt, only two adjacent sets of synchronous pulleys need to be removed. At the same time, when the packing straps are conveyed by the transmission belt 220, the packing straps on both sides are supported by the guide plates, increasing the lateral width and thus increasing the service life of the transmission belt.

[0041] This application also provides a strapping machine, which includes a strapping machine guide device as described in any of the above technical solutions.
