[0033] The following is combined with Figure 1 to Figure 6 The present invention is further described in detail, but is not intended to limit the present invention.

[0034] like Figure 1 As shown, in one embodiment of the present invention, the packaging film conveying device comprises:

[0035] A storage mechanism, the storage mechanism comprises a mounting frame 100, an automatic brake rotating disk 300, a clamping stop component 400, an emergency stop driving component 500 and a storage roller 210; the storage roller 210 is rotatably connected to the mounting frame 100 and is used to store the packaging film 101; the automatic brake rotating disk 300 is fixedly connected to one side end of the storage roller 210; the clamping stop component 400 is connected to the mounting frame 100; and the clamping stop component 400 can be clamped and connected with the automatic brake rotating disk 300; the emergency stop driving component 500 is connected to the mounting frame 100, and the emergency stop driving component 500 can be arranged in contact with the automatic brake rotating disk 300;

[0036] A feeding mechanism, the feeding mechanism comprises a guide conveying roller 600, a bracket 800 and at least one detection sensing component 700; the guide conveying roller 600 is lifted and arranged on the bracket 800; and the input end of the guide conveying roller 600 is connected and communicated with the output end of the storage roller 210 (that is, the input end of the guide conveying roller 600 receives the packaging film 101 conveyed by the output end of the storage roller 210); the detection sensing component 700 is connected to the bracket 800; and the detection sensing component 700 is arranged on the lifting and lowering movement path of the guide conveying roller 600;

[0037] Wherein, the clamping stop component 400 and the emergency stop driving component 500 are both electrically connected to the detection sensing component 700 .

[0038] The technical solution of the present invention triggers a detection sensing component when the guide conveying roller moves to a position of a preset length, so as to prompt the clamping stop component to operate and stop the automatic brake rotating disk and the storage roller, thereby realizing the loading of the preset length of the packaging film; and also triggers another detection sensing component when the guide conveying roller moves to an extreme position, so as to prompt the emergency stop drive component to operate and stop the automatic brake rotating disk and the storage roller, thereby preventing the guide conveying roller from falling off from the bracket, thereby improving the accuracy and stability of loading.

[0039] Specifically, in some embodiments, Figure 1 As shown, at least two feeding conveying rollers 810 are provided on the bracket 800; the guide conveying roller 600 is arranged between two of the feeding conveying rollers 810. Among them, one of the feeding conveying rollers 810 is driven by a feeding driving motor, and all the feeding conveying rollers 810 are pulled by a transmission chain and a transmission wheel. That is to say, the storage roller 210 conveys the packaging film 101 to the feeding conveying roller 810 closest to the storage roller 210; under the rotation and conveying action of the upper end of the feeding conveying roller 810, the packaging film 101 is transferred and conveyed to the bottom of the guide conveying roller 600 to realize the supported suspended conveying state; after passing the bottom of the guide conveying roller 600, the packaging film 101 is conveyed from the side end surface of the guide conveying roller 600 to the upper surface of the next feeding conveying roller 810; thereby realizing the lifting and lowering movement of the guide conveying roller 600 during the conveying process; and when the guide conveying roller 600 moves to a position of a preset length, one of its detection sensing components 700 is triggered to prompt the clamping stop component 400 to operate and stop the automatic brake rotating disk 300 and the storage roller 210; when the guide conveying roller 600 moves to an extreme position, another detection sensing component 700 is triggered to prompt the emergency stop driving component 500 to operate and stop the automatic brake rotating disk 300 and the storage roller 210.

[0040] Specifically, in some embodiments, Figure 1 and 2 As shown, the bracket 800 is provided with a limiting inner cavity 801; the side end of the guide conveying roller 600 is provided with a rotating bearing; the rotating bearing is movably connected to the inside of the limiting inner cavity 801. Among them, the limiting inner cavity 801 is a T-shaped limiting inner cavity. That is to say, through the limiting of the rotating bearing and the action of rotating lifting, the smoothness and stability of the suspension lifting of the guide conveying roller 600 are achieved.

[0041] Specifically, in some embodiments, Figure 1 and 2As shown in FIG. 3 , the bracket 800 is provided with a guide gear bar 640; the side end of the guide conveying roller 600 is also provided with a lifting and rotating gear 630 matched with the guide gear bar 640. The lifting and rotating gear 630 is connected to the guide gear bar 640 by gear transmission. That is to say, through the gear guiding effect of the lifting and rotating gear 630 and the guide gear bar 640, the guiding property of the up and down movement can be improved, and it is beneficial to improve the overall supporting performance.

[0042] Specifically, in some embodiments, Figure 2 and 3 As shown, the guide conveying roller 600 includes a rotating outer cylinder 611 and an installation inner cylinder 612; the rotating outer cylinder 611 is movably connected to the outer surface of the installation inner cylinder 612; the side end of the installation inner cylinder 612 is limitedly connected to the inner surface of the bracket 800 (the middle limit inner cavity 801). Figure 3 As shown, at least two first fixing blocks 614 are provided on one side of the rotating outer cylinder 611 facing the mounting inner cylinder 612; at least two second fixing blocks 615 are provided on one side of the mounting inner cylinder 612 facing the rotating outer cylinder 611; a limiting sphere 613 is fixed on the surface of one side of the first fixing block 614 facing the second fixing block 615; the limiting sphere 613 is clamped on the second fixing block 615 (internal through hole). The rotating outer cylinder 611 is made of a smooth metal material; the mounting inner cylinder 612 is made of stainless steel. This structure can ensure the stability of the overall structure and guarantee the speed and smoothness of the conveying.

[0043] Specifically, in some embodiments, Figure 1 As shown, the detection sensing component 700 includes a preset position sensor 710, a lower limit position sensor 720 and an upper limit position sensor 730; the lower limit position sensor 720, the preset position sensor 710 and the upper limit position sensor 730 are sequentially arranged on the path of the lifting and lowering movement of the guide conveying roller 600; and the preset position sensor 710 is electrically connected to the clamping stop component 400; the lower limit position sensor 720 and the upper limit position sensor 730 are both electrically connected to the emergency stop drive component 500. That is to say, when the guide conveyor roller 600 moves to the preset position sensor 710, the clamping stop component is activated to operate and the automatic brake rotating disk and the storage roller are stopped, thereby achieving the loading of a preset length of the packaging film; and when the guide conveyor roller 600 moves to the lower limit position sensor 720 or the upper limit position sensor 730, the emergency stop drive component is activated to operate and the automatic brake rotating disk and the storage roller are stopped, thereby preventing the guide conveyor roller from falling off the bracket, thereby improving the accuracy and stability of loading.

[0044] Furthermore, if Figure 1 and 2 As shown in FIG. 3 , the side end of the guide conveying roller 600 is further provided with a contact sensing wheel 620; the contact sensing wheel 620 is sleeved on the end of the guide conveying roller 600 and is located inside the lifting and rotating gear 630. That is, the contact sensing wheel 620 is located between the conveying area (middle rotating outer cylinder 611) of the guide conveying roller 600.

[0045] In actual application, when the guide conveying roller 600 moves to the preset position sensor 710, the contact sensing wheel 620 contacts the preset position sensor 710, so that the contact sensor 710 triggers a sensing signal, thereby prompting the clamping stop component 400 to operate and clamp the automatic brake rotating disk 300, so that the storage roller 210 stops rotating, thereby realizing the loading of a preset length of packaging film; when the guide conveying roller 600 moves to the lower limit position sensor 720, the contact sensing wheel 620 contacts the lower limit position sensor 720, so that the lower limit sensor 720 triggers a sensing signal, thereby prompting the emergency stop drive component 500 to operate and clamp the automatic brake rotating disk 300, so that the storage roller 210 stops rotating, thereby realizing the loading of a preset length of packaging film; The brake rotating disc 300 is pressed, so that the automatic brake rotating disc 300 stops, and the storage roller 210 stops rotating, thereby preventing the guide conveying roller 600 from moving downward and falling off from the bracket 800; similarly, when the guide conveying roller 600 moves to the upper limit position sensor 730, the contact sensing wheel 620 contacts the upper limit position sensor 730, so that the upper limit sensor 730 sends a sensing signal, thereby prompting the emergency stop driving component 500 to operate and press the automatic brake rotating disc 300, so that the storage roller 210 stops rotating, thereby preventing the guide conveying roller 600 from moving upward and falling off from the bracket 800, which can improve the accuracy and stability of material loading. In other words, the contact sensing wheel 620 is set to contact the preset position sensor 710, the upper limit position sensor 730 and the lower limit position sensor 720 respectively as the guide conveying roller 600 moves to trigger the sensing signal, and then can perform corresponding actions according to the trigger signal.

[0046] Specifically, in some embodiments, Figure 1 and 4As shown, the detection sensing component 700 includes a sensing sheet 701, a mounting post 7012, a sensing main component 702, a support plate 703, a limiting elastic component 704, a mounting post 705 and a first fixed post 706; the support plate 703 is connected to the bracket 800; the mounting post 705 and the first fixed post 706 are respectively connected to the side surfaces of the support plate 703; one end of the sensing sheet 701 is connected to one end of the limiting elastic component 704 (which can be a spring); the other end of the limiting elastic component 704 is connected to the mounting post 705; the middle part of the sensing sheet 701 is rotatably connected to the first fixed post 706; the sensing main component 702 is connected to the support plate 703; the other end of the sensing sheet 701 can move toward or away from the sensing part of the sensing main component 702. Wherein, the sensing main component 702 can be a pressure sensor or a photoelectric sensor. Wherein, as Figure 4 As shown, the sensing sheet 701 includes a first connecting plate 7011, a contact folding plate 7013 and a connecting folding plate 7014 which are connected in sequence as a whole; the first connecting plate 7011 and the contact folding plate 7013 are arranged obliquely; the contact folding plate 7013 and the connecting folding plate 7014 are arranged to be convex and oblique toward the moving direction of the guide conveying roller 600; and the first connecting plate 7011 is swingably connected to the mounting column 7012. Through the convex folding arrangement of the contact folding plate 323 and the connecting folding plate 324, the guide conveying roller 600 can be quickly contacted, so as to realize the rapid position detection and induction of the guide conveying roller 600, and improve the operation efficiency. Furthermore, a third fixing column 707 is arranged between the limiting elastic member 704 and the mounting column 7012; and the sensing sheet 701 is contacted with the third fixing column 707.

[0047] Specifically, in some embodiments, Figure 1 and 5 As shown, the clamping stop component 400 includes a clamping drive 410 and at least two clamping blocks 420; the clamping blocks 420 are arranged in parallel and movably connected to the clamping drive 410; and a limit groove 401 is provided between two adjacent clamping blocks 420; the automatic brake rotating disk 300 is arranged inside the limit groove 401. The clamping drive 410 and the two clamping blocks 420 form a clamping claw cylinder. That is, when the packaging film 101 and the guide conveying roller 600 move to the preset position sensor 710, that is, the length of the feeding material reaches the preset value, the clamping claw cylinder is driven to move so that the two clamping claws on it move relatively, thereby reducing the space of the limit groove 401, so as to achieve clamping to stop the automatic brake rotating disk 300 from moving, and then realize that the storage roller also stops rotating, so as to realize the feeding of the preset length of the packaging film, and improve the accuracy and stability of the feeding material.

[0048] Specifically, in some embodiments, Figure 1 and 5 As shown, the storage roller 210 includes a support rod 211, a storage inner sleeve 212, an outer sleeve 213 and a locking component 240; the support rod 211 is movably connected to the mounting frame 100; the storage inner sleeve 212 is sleeved on the outer surface of the support rod 211; an assembly inner cavity 216 is provided in the outer sleeve 213; the storage inner sleeve 212 is arranged inside the assembly inner cavity 216; one end of the locking component 240 is inserted into the assembly inner cavity 216, and is detachably connected to the storage inner sleeve 212 and the outer sleeve 213 through threads; the outer surface of the outer sleeve 213 is used to store the packaging film 101; so as to improve the convenience of disassembly and installation, and ensure the stability of assembly. Further, as Figure 5 As shown, the locking component 240 is composed of a locking rod 241 and a locking block 242 that are interconnected; one side end of the locking rod 241 is detachably connected to the storage inner sleeve 212 via a thread; the other side surface of the locking rod 441 is detachably connected to the outer sleeve 423 via a thread; and the locking block 442 is a T-shaped locking structure; the locking block 242 is detachably connected to the other end of the locking rod 241 via a thread.

[0049] Specifically, in some embodiments, Figure 5 As shown, the storage roller 210 (middle and outer sleeve 213) is also provided with a limiting protrusion 220 and a pushing limiting block 230 arranged side by side; a storage inner groove 214 is provided between the pushing limiting block 230, the limiting protrusion 220 and the storage roller 210; the storage inner groove 214 is used for winding the packaging film 101. In other words, by forming an I-shaped storage structure, the placement stability of the packaging film 101 can be ensured to prevent it from falling off and being damaged, thereby improving the orderliness and stability of the feeding.

[0050] Specifically, in some embodiments, Figure 5 As shown, the outer surface of the storage roller 210 (middle and outer sleeve 213) is provided with an adjustment tooth surface 215; the inside of the push limit block 230 is detachably connected to the adjustment tooth surface 215 to increase or decrease the storage length of the storage inner groove 214. The push limit block 230 is provided with an assembly thread surface that matches the adjustment tooth surface 215. This structure can adjust the distance between the push limit block 230 and the limit protrusion 220 by adjusting the tooth surface 215, so as to be suitable for packaging films of different specifications and improve adaptability.

[0051] Specifically, in some embodiments, Figure 1 and 6As shown, the emergency stop driving component 500 includes an emergency stop telescopic cylinder 510 and a buffer abutment block 520; the emergency stop telescopic cylinder 510 is connected to the mounting frame 100 and is drivingly connected to the buffer abutment block 520; the buffer abutment block 520 can make an abutment emergency stop movement with the automatic brake rotating disc 300 or a separation movement away from the automatic brake rotating disc 300. Further, the buffer abutment block 520 can be a rubber block or a suction cup.
