The bundle winding mechanism 3 is arranged on the body 1, and the bundle winding mechanism 3 includes a bundle winding driving motor 31, a bundle winding seat 32, a bundle winding head 33, a bundle pressing rod 34, a depressing motor 35 and a depressing rod 36. The bundle winding seat 32 is connected to the output shaft of the bundle winding driving motor 31, the bundle winding head 33 is arranged on the bundle winding seat 32, the depressing rod 36 is connected to the output shaft of the depressing motor 35, and the middle part of the bundle pressing rod 34 is rotatably matched with the bundle winding seat 32. The coupling mechanism 4 is movably arranged on the body 1, and the coupling mechanism 4 is directly opposite to the bundle winding head 33. During bundling, the first end of the bundling rod 34 abuts against the bundling head 33, and the decompression rod 36 is separated from the second end of the bundling rod 34; during bundling, the decompression rod 36 abuts against the second end of the bundling rod 34, and the first end of the bundling rod 34 is separated from the bundling head 33.

[0035] During the bundling operation, the free end of the tie strap 100 is sent to the winding head 33 through the bundle feeding wheel group 2, and the decompression motor 35 drives the decompression rod 36 to press against the second end of the compression rod 34, and drives the compression rod 34 to rotate, so that the first end of the compression rod 34 is separated from the winding head 33 to form an opening. At this time, the tie strap 100 can be fed into the opening formed when the first end of the compression rod 34 is separated from the winding head 33, completing the bundling of the tie strap 100, and then the decompression motor 35 drives the decompression rod 36 to separate from the second end of the compression rod 34 The pressing rod 34 rotates so that the first end of the pressing rod 34 abuts against the winding head 33, thereby clamping the free end of the tie strap 100. At this time, the winding drive motor 31 drives the winding seat 32 to rotate one circle, and the tie strap 100 is rolled into a tie loop. The items to be bundled are put into the tie loop for bundling, and the bundling wheel group 2 retracts the tie strap, so that the tie strap 100 tightly binds the items to be bundled; after bundling, the combining mechanism moves to the winding head 33 to connect the tie straps 100 here together, cuts the tie straps 100, and completes the bundling.

[0036] The middle of the bunch pressing rod 34 is not the middle of the bunch pressing rod 34, but any position between the two ends of the bunch pressing rod 34. The bunch rolling driving motor 31 is a stepping motor.

[0037] In one embodiment, the winding mechanism 3 further includes a reset spring 37, which is disposed on the winding seat 32, and the two ends of the reset spring 37 respectively abut against the winding seat 32 and the pressing rod 34. When the cable tie 100 is bundled, the pressure release rod 36 drives the pressing rod 34 to rotate, and the reset spring 37 is stressed and in an elastic deformation state; when the cable tie 100 is compressed, the pressure release rod 36 separates from the pressing rod 34, and the reset spring 37 loses force and resets, and drives the first end of the pressing rod 34 to abut against the winding head 33. The reset spring 37 can be a torsion spring.

[0038] In one embodiment, the second end of the compression rod 34 is provided with a limiting groove 342 matched with the back-pressure rod 36 , and when the back-pressure rod 36 drives the compression rod 34 to rotate, the compression rod 34 is inserted into the limiting groove 342 .

[0039] In one embodiment, the joining mechanism 4 includes a joining drive motor 41, a joining bracket 42, a heater slider 43 and a welding head 44. The joining bracket 42 is arranged on the main body 1. The joining bracket 42 is provided with a guide rail 421. The heater slider 43 slides with the guide rail 421. The welding head 44 is arranged on the side of the heater slider 43 close to the winding head 33.

A feed frame 5 is arranged between the feed wheel assembly 2 and the winding mechanism 3 to support the tie strap 100. The guide groove 51 and the feed groove 52 limit and guide the tie strap 100, so that the tie strap 100 can be ready to be fed into the opening formed by separating the first end of the compression rod 34 and the winding head 33.

[0043] In one embodiment, the beam-in wheel assembly 2 is provided with a beam-in size photoelectric sensor 22 , and the beam-in size photoelectric sensor 22 is used to control the moving distance of the cable tie 100 during beam-in or beam-out.

The contact area between the crimping head 341 and the crimping head 33 is large, which is convenient for clamping the cable ties 100 of different widths. In addition, the crimping head 33 of the plate-like structure can better provide a force point for the welding head 44, which is convenient for the hot-melt connection of the cable ties 100.

[0046] In one embodiment, the body 1 includes a base 11, a shell 12, and one or more mounting frames 13. The shell 12 is disposed on the base 11, and the mounting frame 13 is disposed in the shell 12. A strapping reel bin 111 for placing a strapping reel is disposed in the base 11. The strapping machine further includes one or more guide pulleys 7.

The strapping reel is placed in the strapping reel bin 111, and the strapping tape 100 is guided to the strapping wheel set 2 by the guide pulley 7, and then sent to the winding mechanism 3 by the strapping wheel set 2 for winding and bundling operation.

[0047] A configuration of the guide pulley 7 is as follows: the guide pulley 7 may be configured on the outside of the housing 12 to facilitate adjustment of the cable tie 100 .

[0048] Another arrangement of the guide pulley 7 is that the guide pulley 7 can be arranged on the inner side of the housing 12 or on a mounting frame 13 inside the housing 12, which can keep the cable tie 100 clean.

[0049] In one embodiment, the guide pulley 7 includes a wheel seat 71, a rotating shaft 72, a rotating drum 73 and a stopper 74. The rotating shaft 72 and the stopper 74 are arranged on the wheel seat 71 in parallel and at a distance from each other. The rotating drum 73 is rotatably sleeved on the rotating shaft 72. The cable tie 100 is wound around the rotating drum 73, and the stopper 74 can prevent the cable tie 100 from being separated from the rotating drum 73.

[0050] In one embodiment, a display screen 9 and a control button 10 are provided on the housing 12 to adjust the operating state of the strapping machine.

The material photoelectric detector 8 can detect whether there are bundled objects in the bundling mechanism 3 and the size of the objects to be bundled, and then link the bundling wheel group 2 to perform bundling and unbundling operations.

[0053] In one embodiment, a battery 15 is further provided in the shell 12. The battery 15 can store electrical energy and can be used normally without an external power supply, so it is convenient to carry and use outside, and can avoid the situation where the belt machine suddenly stops running due to sudden power failure, causing damage to internal parts.

[0054] The existing manual bundling uses rubber bands, but the elasticity of the rubber bands will cause the tied part to deform, increase the pressure in the sample catheter and the blood bag, and cause the blood cells in the sample catheter and the blood bag to be destroyed during the storage period, affecting the accuracy and effectiveness of the blood matching experiment. The binding band 100 used in each embodiment of the present application is an inelastic binding band 100, the tied object will not be deformed, the blood cells in the sample catheter will not be destroyed during the blood storage period, and the effectiveness and accuracy of blood matching are improved.
