[0030] Preferably, in the gluing step, when the left end of the grid bridge is moved to align with the adhesive tape roll, the second conveying assembly is controlled to suspend driving the grid bridge, and the adhesive roller is controlled to rotate to the position right below the grid bridge along with the adhesive element; then, the pressing element is driven to rotate towards the adhesive element, and the pressing block at the upper end of the pressing element presses the adhesive tape between the adhesive tape roll and the grid bridge onto the packaging tape around the periphery of the grid bridge; subsequently, the adhesive element is driven to rotate away from the pressing element until the adhesive roller is separated from the adhesive tape, and then the pressing element is driven to rotate away from the adhesive element; finally, the gluing assembly is driven to start rotating around the periphery of the channel until at least one turn of the adhesive tape is wound around the packaging tape on the periphery of the grid bridge, the adhesive roller is rotated again to the position right below the grid bridge along with the adhesive element, and the gluing assembly is continuously rotated for one turn, until the adhesive tape between the grid bridge and the adhesive tape roll is adhered to the adhesive roller, and then the cutting element is driven to rotate towards the adhesive element, and the cutter at the upper end of the cutting element cuts the adhesive tape between the grid bridge and the adhesive roller.

[0031] Preferably, in the cutting step, when the packaging tape completely wraps around the periphery of the left end of the grid bridge, the first clamping assembly and the second clamping assembly are simultaneously moved to the right until the first clamping assembly and the second clamping assembly clamp the packaging tape between the grid bridge and the packaging tape roll, and then the cutting assembly is moved to the right to cut the packaging tape between the first clamping assembly and the second clamping assembly; after the packaging tape is cut, the second clamping assembly first releases the packaging tape close to the end of the grid bridge, the second conveying assembly continues to drive the grid bridge to move to the right, and the cutting assembly, the first clamping assembly, and the second clamping assembly move to the left to the initial position.

[0036] Compared with the prior art, the application has the following beneficial effects: (1) when the grid bridge is packaged by the automatic packing machine, the grid bridge is only needed to be placed on the first conveying assembly, and then the grid bridge is automatically conveyed from left to right through the channel by the first conveying assembly and the second conveying assembly. When the right end of the grid bridge moves to align with the packaging tape roll, the grid bridge is first stopped, the first clamping assembly is driven to clamp the starting end of the packaging tape and move leftward for a distance, the winding assembly is then driven to start rotating around the channel in the circumferential direction, so that the packaging tape is wound around the outer periphery of the right end of the grid bridge, and the starting end of the packaging tape is automatically tightened on the outer periphery of the grid bridge after two to three turns of the packaging tape are wound. Then, the first clamping assembly is controlled to loosen the starting end of the packaging tape, the grid bridge is continuously driven to move rightward, and the winding assembly is continuously driven to rotate around the channel, so that the packaging tape is automatically wound around the outer periphery of the grid bridge in a spiral direction. When the outer periphery of the left end of the grid bridge is fully wound with the packaging tape, the grid bridge is first stopped, the first clamping assembly is then driven to slide rightward, the packaging tape between the grid bridge and the packaging tape roll is clamped by the first clamping assembly, the cutting assembly is driven to slide rightward, so that the packaging tape between the grid bridge and the first clamping assembly is automatically cut off. The packaging tape close to the grid bridge after being cut off can move rightward with the grid bridge, and the packaging tape close to the packaging tape roll after being cut off (i.e. the starting end of the packaging tape on the packaging tape roll) moves leftward for a distance with the first clamping assembly, so as to be used for packaging next time. When the left end of the grid bridge moves rightward to align with the adhesive tape roll, the grid bridge is first stopped, and the starting end of the adhesive tape on the adhesive tape roll is pressed onto the packaging tape (on the outer periphery of the left end of the grid bridge) by the cutting adhesive assembly. Then, the adhesive assembly is driven to start rotating around the channel in the circumferential direction, so that the adhesive tape is automatically wound around the packaging tape on the outer periphery of the left end of the grid bridge. When at least one turn of the adhesive tape is wound on the outer periphery of the left end of the grid bridge, the packaging tape close to the grid bridge after being cut off is automatically tightened on the outer periphery of the grid bridge. Finally, the adhesive tape between the grid bridge and the adhesive tape roll is automatically cut off by the cutting adhesive assembly, and the grid bridge is continuously driven to move rightward, so that the packaged grid bridge can be taken off from the second conveying assembly.

[0037] (2) When the automatic packing machine is used for packing, the whole process is simple to operate, has high automation degree, work efficiency is improved by at least one time, manual work load is less, and manual cost is reduced by at least one half; moreover, the packing belt can be made of plastic material with lower cost, and is made by weaving or by heating and plasticizing extrusion molding, compared with the traditional packing method using paper boxes, the packing method using the packing belt can reduce the material cost by at least one half, and has higher strength, even if it is drenched or rained during transportation, it will not be damaged.

Figure 12 As shown, the cutting assembly 9 is disposed on the frame 1; when the left end of the mesh bridge 700 moves to the right and aligns with the tape roll 900, the cutting assembly 9 is used to press the starting end of the tape 901 on the tape roll 900 onto the packaging tape 801; when at least one turn of tape 901 is wrapped around the packaging tape 801 on the outer periphery of the left end of the mesh bridge 700, the cutting assembly 9 is used to cut the tape 901 between the mesh bridge 700 and the tape roll 900.

[0063] When using this automatic packaging machine to package the mesh cable tray 700, simply place the mesh cable tray 700 onto the first conveyor assembly 2, and the mesh cable tray 700 will be automatically conveyed from left to right through the channel 11 via the first conveyor assembly 2 and the second conveyor assembly 3. When the right end of the mesh cable tray 700 moves to align with the packaging tape roll 800, first stop driving the mesh cable tray 700, and then clamp the starting end of the packaging tape 801 through the first clamping assembly 5 and move it to the left a certain distance (e.g., ...). Figure 7 (As shown), the winding assembly 4 is then driven to rotate circumferentially around the channel 11, causing the packaging tape 801 to wrap around the outer periphery of the right end of the grid bridge 700. After the packaging tape 801 wraps around two to three times, the starting end of the packaging tape 801 will automatically be secured to the outer periphery of the grid bridge 700. Then, the first clamping assembly 5 is controlled to release the starting end of the packaging tape 801, and the grid bridge 700 is driven to move to the right. The winding assembly 4 is also driven to rotate around the channel 11, so that the packaging tape 801 is automatically wound around the outer periphery of the grid bridge 700 in a spiral direction. When the outer periphery of the left end of the grid bridge 700 is fully wrapped with the packaging tape 801, the drive of the grid bridge 700 is stopped, and the first clamping assembly 5 is driven to slide to the right. The first clamping assembly 5 clamps the packaging tape 801 between the grid bridge 700 and the packaging tape roll 800 (as shown). Figure 8 and Figure 9As shown in FIG. 6, when the left end of the grid bridge 700 moves to the right to align with the wrapping tape roll 800, the driving of the grid bridge 700 is stopped first, and then the cutting tape assembly 9 is used to press the starting end of the wrapping tape 801 on the wrapping tape roll 800 onto the wrapping tape 801 on the outer periphery of the left end of the grid bridge 700; then, the tape sticking assembly 8 is driven to start rotating around the circumference of the channel 11, so as to automatically wrap the wrapping tape 801 on the outer periphery of the left end of the grid bridge 700, until at least one turn of the wrapping tape 801 is wrapped on the outer periphery of the left end of the grid bridge 700, that is, the wrapping tape 801 that is cut off near the end of the grid bridge 700 is automatically tightened on the outer periphery of the grid bridge 700; finally, the cutting tape assembly 9 is used to automatically cut off the wrapping tape 801 between the grid bridge 700 and the wrapping tape roll 800, and then the grid bridge 700 is continuously driven to move to the right, until the wrapped grid bridge 700 is taken off from the second conveying assembly 3. The above-mentioned entire process is simple to operate, has high automation degree, improves work efficiency by at least one time, reduces labor workload, and reduces labor cost by at least one time; moreover, the wrapping tape 801 can be made of a plastic material such as PPC, PE, PPS, etc., which is woven or extruded by heating and plasticizing, compared with the traditional way of packing by using a carton, the packing way by using the wrapping tape 801 can reduce material cost by at least one time, and has higher strength, and even if it is drenched or rained during transportation, it will not be damaged.

[0064] Referring to Figure 5 and Figure 6 In the embodiment, the automatic packing machine further comprises a second clamping assembly 6, which is arranged to be slidable leftward and rightward on the rack 1, and is located on the side of the cutting assembly 7 deviated from the first clamping assembly 5; when the wrapping tape 801 is wrapped to the left end of the grid bridge 700, the first clamping assembly 5 and the second clamping assembly 6 are simultaneously slid to the right, until the first clamping assembly 5 and the second clamping assembly 6 clamp the wrapping tape 801 at the same time, the cutting assembly 7 is slid to the right, until the cutting assembly 7 cuts off the wrapping tape 801 between the first clamping assembly 5 and the second clamping assembly 6, and then the second clamping assembly 6 releases the wrapping tape 801. As shown in FIG. 5, the first clamping assembly 5 and the second clamping assembly 6 can tighten the wrapping tape 801 on both sides of the cutting assembly 7, so as to ensure that the cutting assembly 7 can more stably cut off the wrapping tape 801. Figure 9

[0065] Referring to Figure 8 ​In the embodiment, the automatic packing machine further comprises a blowing assembly 100, which is arranged on the frame 1 and located on the side of the cutting assembly 7 deviated from the first clamping assembly 5. When the second clamping assembly 6 releases the packing belt 801, the blowing assembly 100 blows air to the packing belt 801 between the grid bridge 700 and the cutting assembly 7 to force the cut packing belt 801 to adhere to the grid bridge 700. Under the action of the blowing assembly 100, when the second clamping assembly 6 releases the packing belt 801, the blowing assembly 100 blows air to the cut packing belt 801, so that the packing belt 801 can stably adhere to the grid bridge 700, and the packing belt 801 wound around the outer periphery of the grid bridge 700 can be prevented from loosening.

[0066] With reference to Figure 17 In the embodiment, the automatic packing machine further comprises a positioning assembly 200, and the front and rear sides of the first conveying assembly 2 and the front and rear sides of the second conveying assembly 3 are slidably connected with the positioning assembly 200. When the two positioning assemblies 200 corresponding in the front-rear direction are in contact with the grid bridge 700, the movement of the grid bridge 700 in the front-rear direction is limited. The two positioning assemblies 200 on the front and rear sides can limit the movement of the grid bridge 700 in the front-rear direction, and the two positioning assemblies 200 corresponding in the front-rear direction can adapt to the passing of the grid bridge 700 with different widths.

[0067] With reference to Figure 1 and Figure 22 In the embodiment, the automatic packing machine further comprises a pressing assembly 300, and the upper sides of the first conveying assembly 2 and the second conveying assembly 3 are slidably connected with the pressing assembly 300. When the pressing assembly 300 moves downward to be in contact with the grid bridge 700, the upward movement of the grid bridge 700 is limited, so that the grid bridge 700 is prevented from being lifted from the first conveying assembly 2 or the second conveying assembly 3 during the packing process, the safety is higher, and the stability is better.

[0068] With reference to Figure 17 In the embodiment, the automatic packing machine further comprises a sensing assembly 400, and the sensing assembly 400 is arranged on the first conveying assembly 2 and the second conveying assembly 3 and is used for detecting the movement position of the grid bridge 700. The movement position of the grid bridge 700 can be detected by the sensing assembly 400, so that corresponding operations can be automatically performed.

[0069] The specific structure of the winding assembly 4 is not limited in the application, as long as it can drive the packing belt roll 800 to rotate around the circumference of the channel 11 and ensure that the packing belt roll 800 can rotate by itself. Only one specific structure is provided below for reference. Figure 2 、 Figure 3 and Figure 4The winding assembly 4 comprises a first rotating ring 41, a first fixed seat 42, and a first counterweight seat 43. The first rotating ring 41 is rotatably installed on the rack 1. The first fixed seat 42 and the first counterweight seat 43 are symmetrically arranged on the first rotating ring 41. The first fixed seat 42 comprises a fixed plate 421, a fixed shaft 422, a spring 423, and a locking ring 424. The fixed plate 421 is fixed on the first rotating ring 41. The fixed shaft 422 is fixed on the fixed plate 421 in the left-right direction. The wrapping tape roll 800 is rotatably sleeved on the fixed shaft 422. The locking ring 424 is threadedly connected to the fixed shaft 422. The spring 423 is sleeved on the fixed shaft 422, and the spring 423 is located between the locking ring 424 and the wrapping tape roll 800. When the locking ring 424 is rotated, the rotational resistance of the wrapping tape roll 800 on the fixed shaft 422 can be adjusted. When the first rotating ring 41 is driven to rotate, the fixed shaft 422 (i.e., the wrapping tape roll 800) can be driven to rotate around the circumference of the channel 11, so that the wrapping tape 801 on the wrapping tape roll 800 can be wound on the outer circumference of the grid bridge 700. At the same time, the wrapping tape 801 can be self-rotated by being pulled by the wrapping tape roll 800. In addition, the self-rotation of the wrapping tape roll 800 should not be too tight or too loose. If it is too tight, the pulling force of the wrapping tape 801 on the wrapping tape roll 800 will be too large, which can easily cause the wrapping tape 801 to break. If it is too loose, the wrapping tape 801 can be loosely wound on the grid bridge 700, and the wrapping effect is poor. Therefore, the pressure of the spring 423 on the wrapping tape roll 800 can be adjusted by rotating the locking ring 424, so that the rotational resistance of the wrapping tape roll 800 can be adjusted to the best state. The first counterweight seat 43 can play a counterweight role, which can improve the stability of the first rotating ring 41 during rotation. The rotatable installation mode of the first rotating ring 41 is not limited, and preferably, an annular groove 411 is coaxially arranged on the outer circumference of the first rotating ring 41. At least three driving wheels 44 are rotatably installed on the rack 1. The at least three driving wheels 44 are respectively rollingly connected in the annular groove 411, and the at least three driving wheels 44 can clamp the first rotating ring 41. When at least one of the driving wheels 44 is driven to rotate, the first rotating ring 41 can be driven to rotate.

[0070] The specific structure of the first clamping assembly 5 is not limited in the present application. Only one structure is provided below for reference: Figure 1 、 Figure 5 and Figure 6The rack 1 is provided with a mounting rack 12, and a sliding rack 13 is slidably connected to the mounting rack 12; the first clamping assembly 5 comprises a first lower clamping plate 51, a first upper clamping plate 52 and a first telescopic piece 53; the left end of the first lower clamping plate 51 is fixed to the sliding rack 13, the left end of the first upper clamping plate 52 is hingedly connected to the left end of the first lower clamping plate 51, and the two ends of the first telescopic piece 53 are respectively hingedly connected to the first upper clamping plate 52 and the sliding rack 13; when the first telescopic piece 53 is elongated, a first clamping area for clamping the packaging belt 801 is formed between the first upper clamping plate 52 and the first lower clamping plate 51. In use, first, the first telescopic piece 53 is controlled to be shortened, so that the first upper clamping plate 52 is rotated to a vertical position, then the sliding rack 13 is driven to slide to the right, until the first lower clamping plate 51 moves to below the packaging belt 801, then the first telescopic piece 53 is controlled to be elongated, and the first clamping area formed between the first upper clamping plate 52 and the first lower clamping plate 51 can clamp the packaging belt 801 (as shown in Figure 9 The surface of the first lower clamping plate 51 facing the first upper clamping plate 52 is adapted to be provided with double-sided adhesive tape 54 for repeatedly adhering the packaging belt 801. During the process of first mounting the packaging belt roll 800 on the fixed shaft 422 and subsequent roll changing, the starting end of the packaging belt 801 on the packaging belt roll 800 is manually pulled onto the double-sided adhesive tape 54 to temporarily fix the packaging belt 801, and after the manual operation is separated from the operation area, the packaging belt 801 on the double-sided adhesive tape 54 is clamped by the first upper clamping plate 52 to ensure that the packaging belt 801 does not fall off from the first clamping area during the operation process. When the starting end of the packaging belt 801 is tightly wound on the grid bridge 700 by the packaging belt 801 itself, the first upper clamping plate 52 is controlled to rotate upward, and during the process of driving the grid bridge 700 to move to the right by the first conveying assembly 2, the grid bridge 700 generates a pulling force on the packaging belt 801 on the double-sided adhesive tape 54, so that the packaging belt 801 is separated from the double-sided adhesive tape 54. The left and right sliding installation mode between the sliding rack 13 and the mounting rack 12 is prior art, which will not be described in detail here.

[0071] The specific structure of the second clamping assembly 6 is not limited in the application, and only one structure is provided for reference below: Figure 5 and Figure 6The second clamping member comprises a second lower clamping plate 61, a second upper clamping plate 62 and a second telescopic member 63. The left end of the second lower clamping plate 61 is fixed to the sliding frame 13, the left end of the second upper clamping plate 62 is hingedly connected to the left end of the second lower clamping plate 61, and the two ends of the second telescopic member 63 are respectively hingedly connected to the second upper clamping plate 62 and the sliding frame 13. When the second telescopic member 63 is elongated, a second clamping area for clamping the packaging belt 801 is formed between the second upper clamping plate 62 and the second lower clamping plate 61. In use, first, the second telescopic member 63 is controlled to be shortened, so that the second upper clamping plate 62 is rotated to a vertical position, then the sliding frame 13 is driven to slide to the right, until the second lower clamping plate 61 moves to below the packaging belt 801, then the second telescopic member 63 is controlled to be elongated, and the second clamping area formed between the second upper clamping plate 62 and the second lower clamping plate 61 can clamp the packaging belt 801 (as shown in Figure 9 The surface of the second upper clamping plate 62 facing the second lower clamping plate 61 is adapted to be provided with an elastic pad 64, which can increase the clamping force of the second clamping area on the packaging belt 801. When the second upper clamping plate 62 is rotated upward, the elastic pad 64 can be separated from the packaging belt 801, preventing the packaging belt 801 from being adsorbed on the elastic pad 64 due to negative pressure.

[0072] The specific structure of the cutting assembly 7 is not limited in the present application, and only one structure is provided below for reference: referring to Figure 6 The cutting assembly 7 comprises a cutter 71, a guide column 72, a guide block 73 and a third telescopic member 74. The guide column 72 is fixed to the sliding frame 13 in the left-right direction, the guide block 73 is slidably connected to the guide column 72, and one end of the cutter 71 is fixed to the guide block 73. The third telescopic member 74 is fixed to the sliding frame 13, and the telescopic end of the third telescopic member 74 is connected to the guide block 73. By controlling the extension and contraction of the third telescopic member 74, the cutter 71 can be driven to move left and right relative to the sliding frame 13. The sliding connection between the guide block 73 and the guide column 72 can improve the accuracy of the left-right movement of the cutter 71. The sliding connection between the guide block 73 and the guide column 72 is a prior art, which will not be described in detail here. In addition, the first telescopic member 53, the second telescopic member 63 and the third telescopic member 74 are all prior art, for example, they can be air cylinders, oil cylinders, etc., which will not be exemplified one by one here.

[0073] The specific structure of the adhesive application assembly 8 is not limited in the present application, as long as it can drive the adhesive tape roll 900 to rotate around the circumference of the channel 11 and ensure that the adhesive tape roll 900 can rotate by itself. Only one specific structure is provided below for reference: referring to Figure 10 and Figure 11The adhesive assembly 8 comprises a second rotating ring 81, a second fixed seat 82 and a second counterweight seat 83. The second rotating ring 81 is rotatably installed on the rack 1, and the second fixed seat 82 and the second counterweight seat 83 are symmetrically arranged on the second rotating ring 81. The second fixed seat 82 comprises a connecting seat 821, an expansion ring 822 and a locking bolt 823. The connecting seat 821 is fixed on the second rotating ring 81, the locking bolt 823 is threadedly connected to the connecting seat 821, the expansion ring 822 is sleeved on the locking bolt 823, and the adhesive tape roll 900 is rotatably sleeved on the expansion ring 822. When the locking bolt 823 is rotated, the expansion ring 822 is deformed radially to adjust the rotational resistance of the adhesive tape roll 900 on the expansion ring 822. The second counterweight seat 83 functions as a counterweight to improve the stability of the second rotating ring 81 during rotation. The rotatable installation mode of the second rotating ring 81 is not limited, for example, it can be the same as that of the first rotating ring 41, which will not be described in detail here. When the second rotating ring 81 is driven to rotate, the expansion ring 822 (adhesive tape roll 900) is driven to rotate around the circumference of the channel 11, and the adhesive tape 901 on the adhesive tape roll 900 is wound on the packaging tape 801 on the outer circumference of the grid bridge 700. At the same time, the adhesive tape 901 is automatically pulled to rotate the adhesive tape roll 900. In addition, the self-rotation process of the adhesive tape roll 900 should not be too tight or too loose. If it is too tight, the pulling force of the adhesive tape 901 on the adhesive tape roll 900 will be too large, which may easily cause the adhesive tape 901 to break or deform. If it is too loose, the adhesive tape roll 900 is prone to falling off. Therefore, the locking bolt 823 can be rotated to force the expansion ring 822 to deform radially, so that the rotational resistance between the expansion ring 822 and the adhesive tape roll 900 can be adjusted to the optimal state. In addition, a gasket 824 (as shown in Figure 11 ) is arranged between the bolt and the expansion ring 822 to reduce the wear of the expansion ring 822.

[0074] The specific structure of the tapping assembly 9 is not limited in the present application, and only one specific structure is provided for reference below: Figure 12 The tapping assembly 9 comprises a pressing member 91, a sticking member 92 and a tapping member 93. The pressing member 91, the sticking member 92 and the tapping member 93 are arranged in sequence along the front-rear direction. The lower ends of the pressing member 91, the sticking member 92 and the tapping member 93 are rotatably arranged on the rack 1. The upper end of the sticking member 92 is rotatably connected with a sticking roller 921. The rotating axes of the sticking roller 921, the pressing member 91, the sticking member 92 and the tapping member 93 are parallel to the rotating axis of the adhesive tape roll 900. The upper end of the pressing member 91 is provided with a pressing block 911, and the upper end of the tapping member 93 is provided with a tapping cutter 931. Figure 13 and Figure 14As shown, when the left end of the grid bridge 700 moves right to align with the adhesive tape roll 900, the adhesive roller 921 rotates with the adhesive element 92 to be right below the grid bridge 700, so as to paste the starting end of the adhesive tape 901 on the adhesive tape roll 900 to the adhesive roller 921. When the adhesive element 92 rotates towards the pressing element 91, the pressing block 911 is forced to press the adhesive tape 901 between the adhesive tape roll 900 and the adhesive roller 921 to the packaging belt 801 on the outer periphery of the left end of the grid bridge 700; when the adhesive element 92 rotates away from the pressing element 91 until the adhesive roller 921 is separated from the adhesive tape 901, the pressing element 91 rotates away from the adhesive element 92, so that the adhesive pasting assembly 8 winds the adhesive tape 901 on the packaging belt 801 on the outer periphery of the grid bridge 700. As shown in Figure 15 and Figure 16 As shown, when the packaging belt 801 on the outer periphery of the left end of the grid bridge 700 is wound with at least one circle of the adhesive tape 901, the adhesive roller 921 rotates with the adhesive element 92 to be right below the grid bridge 700, and waits for the adhesive pasting assembly 8 to continue to rotate for one circle, until the adhesive tape 901 between the grid bridge 700 and the adhesive tape roll 900 is pasted to the adhesive roller 921, the cutting element 93 rotates towards the adhesive element 92 to drive the cutting knife 931 to cut the adhesive tape 901 between the grid bridge 700 and the adhesive roller 921. The rotatable mounting mode of the pressing element 91, the adhesive element 92 and the cutting element 93 are all prior art, for example, as shown in Figure 12 their lower ends are rotatably connected with shafts and bearings, and are respectively driven by the driving cylinder 94 (both ends are hingedly connected).

[0075] Referring to Figure 14 In this embodiment, the elastic plate 912 is adapted to be arranged between the pressing block 911 and the pressing element 91, and deforms when the pressing block 911 presses the adhesive tape 901 to the packaging belt 801, so as to force the pressing block 911 to fully contact with the packaging belt 801. The pressing block 911 is preferably made of soft material such as rubber or foam, so as to avoid scratching the adhesive tape 901. In addition, the edges of the part of the pressing block 911 that contacts with the adhesive tape 901 can be transitioned by fillets. In addition, referring to Figure 16 In order to avoid the cut adhesive tape 901 adhering to the second conveying assembly 3, the brush 932 is adapted to be arranged on the upper end of the cutting element 93, and forces the cut adhesive tape 901 to be pressed to the packaging belt 801 when the cutting knife 931 cuts the adhesive tape 901.

[0076] The specific structure of the air blowing assembly 100 is not limited in the present application, and only one structure is provided below for reference: referring to Figure 2The blowing assembly 100 comprises a bendable pipe 101, an air nozzle 102 and an automatic control valve; the bendable pipe 101 is fixed to the rack 1, one end of the bendable pipe 101 is communicated with the air nozzle 102, and the other end of the bendable pipe 101 is communicated with the air source through the automatic control valve. The orientation of the air nozzle 102 can be changed by bending the bendable pipe 101, so as to adjust the optimal orientation of the air nozzle 102 according to the actual situation. The bendable pipe 101 and the automatic control valve are prior art.

[0077] The specific structure of the positioning assembly 200 is not limited in the present application, and only one structure is provided below for reference: referring to Figure 17 and Figure 20 The positioning assembly 200 comprises a support frame 201 and a vertical roller 202; one support frame 201 is slidably connected to the front side of the first conveying assembly 2, the rear side of the first conveying assembly 2, the front side of the second conveying assembly 3 and the rear side of the second conveying assembly 3; at least two vertical rollers 202 are rotatably connected to each support frame 201, and the at least two vertical rollers 202 on each support frame 201 are spaced apart in the left-right direction. The vertical roller 202 can limit the grid bridge 700 in the front-rear direction to prevent the grid bridge 700 from deviating during conveying; at the same time, the vertical roller 202 can rotate to reduce the frictional resistance between the grid bridge 700. The support frame 201 can be slidably limited in the front-rear direction by a slide rail, and the same lead screw 204 can be used to drive the two support frames 201 corresponding in the front-rear direction, i.e. the two ends of the lead screw 204 are installed through bearings, two sections of external threads in opposite directions are provided on the lead screw 204, and the two support frames 201 are threadedly connected to the lead screw 204; when the driving motor 203 drives the lead screw 204 to rotate, the two support frames 201 can be simultaneously driven to slide towards or away from each other. The rotatable mounting manner between the vertical roller 202 and the support frame 201 is prior art.

[0078] The specific structure of the pressing assembly 300 is not limited in the present application, and only one structure is provided below for reference: referring to Figure 22The pressing assembly 300 includes a fixed frame 301 and a horizontal roller 302. The fixed frame 301 is slidably mounted on the frame 1, and the horizontal roller 302 is rotatably connected to the fixed frame 301 and arranged in the front-to-back direction. The horizontal roller 302 can limit the movement above the mesh bridge 700 to prevent the mesh bridge 700 from being lifted during packaging. In addition, the horizontal roller 302 can rotate, which can reduce the frictional resistance between the horizontal roller 302 and the mesh bridge 700. The sliding mounting method of the fixed frame 301 is existing technology. For example, the fixed frame 301 uses a slide rod 303 for vertical sliding limit and a pressing cylinder 304 to drive the fixed frame 301 to slide vertically. The rotatable mounting method of the horizontal roller 302 is existing technology, in which multiple parallel horizontal rollers 302 are rotatably mounted on the same fixed frame 301.

[0079] This application does not limit the specific structure of the sensing component 400; the following is only one structure for reference: (Refer to...) Figure 17 The sensing component 400 includes a generator 401 and a receiver 402. Generators 401 and receivers 402 are respectively provided on the front and rear sides of the first conveying component 2 and the front and rear sides of the second conveying component 3. The generator 401 and receiver 402 themselves are existing technologies. Figure 18 , Figure 19 as well as Figure 20 As shown, the first conveying assembly 2 is also provided with a shielding assembly 500. The shielding assembly 500 includes a fixing rod 501 and a shielding plate 502. The lower end of the fixing rod 501 is fixed to the first conveying assembly 2, and one end of the shielding plate 502 is fixed to the fixing rod 501. When the mesh bridge 700 moves to the right and contacts the shielding plate 502, the shielding plate 502 deforms (e.g., Figure 19 (As shown by the dashed line) to block the generator 401 on the first conveying assembly 2, so that the corresponding receiver 402 cannot receive the signal emitted by the generator 401; when the grid bridge 700 moves to the right and separates from the blocking plate 502, the blocking plate 502 automatically resets (as shown by the dashed line). Figure 19 (Shown by solid lines). Before packaging, the mesh cable tray 700 has a skeletal structure, and the area that can shield the generator 401 is relatively narrow. When the shielding plate 502 is installed, the mesh cable tray 700 will push the shielding plate 502 to deform when passing through, thereby effectively shielding the generator 401 and improving stability. After packaging, the mesh cable tray 700 is wrapped with packaging straps 801. Therefore, when it moves on the second conveyor assembly 3, the packaging straps 801 can effectively shield the generator 401, so the shielding assembly 500 is not needed on the second conveyor assembly 3.

[0080] Reference Figure 18 as well as Figure 21In the embodiment, the automatic packing machine further comprises a stop component 600 which is slidably arranged on the first conveying component 2 in the up-down direction or in the front-rear direction. When the stop component 600 moves to contact the right side of the grid bridge 700, the movement of the grid bridge 700 to the right is limited. When the operator is operating in the dangerous area (for example, replacing the packing tape roll 800 or the adhesive tape roll 900), the stop component 600 can be controlled to move to the right end of the grid bridge 700 to limit the movement of the grid bridge 700 to the right on the first conveying component 2, thereby ensuring the safety of the operator. The slidable arrangement of the stop component 600 is a prior art, for example, the stop component 600 is directly driven by a stop cylinder 601 to move in the corresponding direction.

[0081] The application further provides a packing method of the automatic packing machine, which comprises a preparation step, a feeding step, a packing step, a cutting step, a gluing step and a discharging step.

[0082] The preparation step includes the following steps. A packing tape roll 800 and an adhesive tape roll 900 are provided.
