DETAILED DESCRIPTION

[0021] The specific implementation methods of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, an automatic bag cutting and feeding system for bagged meat and bone materials includes a first conveying mechanism 10, a second conveying mechanism 20 and a feeding mechanism 30. The conveying end of the first conveying mechanism 10 is vertically connected to the conveying starting end of the second conveying mechanism 20, and the feeding mechanism 30 is arranged at the conveying end of the second conveying mechanism 20.

[0023] like Figure 2-Figure 4As shown, the first conveying mechanism 10 includes a first conveying frame 11, on which a first flat support plate 111 is fixedly provided, and one end of the first flat support plate 111 close to the second conveying mechanism 20 is smoothly connected to an inclined slide plate 112, and the first conveying frame 11 is rotatably connected to a first active roller shaft 131 at one end in the conveying direction, and is rotatably connected to a first driven roller shaft 132 at the other end, and two first conveying belts 133 arranged at intervals are transmission-connected between the first active roller shaft 131 and the first driven roller shaft 132, and the two first conveying belts 133 are both connected to the first conveying belts 133. The first conveyor frame 11 is provided with a first motor 12, which is used to drive the first active roller 131 to rotate, thereby driving the two first conveyor belts 133 to rotate. The friction force of the two first conveyor belts 133 can drive the loading bag above them to slide laterally on the first flat pallet 111. The function of the first flat pallet 111 is to prevent the loading bag from leaking materials from the incision at the bottom. After the loading bag slides onto the inclined slide 112, it can slide down the inclined slide 112 and then be thrown onto the second conveying mechanism 20 by inertia.

[0024] Further, a first driving gear 1311 is fixedly connected to the first driving roller shaft 131, a first transfer shaft 14 is rotatably connected to the first conveyor frame 11, a first driven gear 141 is fixedly connected to the first transfer shaft 14, the first driving gear 1311 is meshed with the first driven gear 141, so that the rotation directions of the first driving roller shaft 131 and the first transfer shaft 14 are opposite, a first linkage shaft 16 is rotatably connected to the first conveyor frame 11 at a position below the first flat support plate 111, the first transfer shaft 14 and the first linkage shaft 16 are connected through a first belt transmission assembly 15, and three first swing arms 17 are provided on the first linkage shaft 16 along its axial direction, and one of each first swing arm 17 The ends are rotatably connected to the first linkage shaft 16, and the other end of each first swing arm 17 is rotatably connected to the first knife shaft 171, the axial direction of each first knife shaft 171 is perpendicular to the conveying direction of the first conveying mechanism 10, and each first knife shaft 171 is fixedly connected to a first transfer pulley 1711 and a first circular cutter 1712, respectively. The first linkage shaft 16 is fixedly connected to a plurality of first transfer pulleys 1711 in a one-to-one correspondence with a plurality of first linkage pulleys 161, and a first linkage belt 162 is transmission-connected between the corresponding first linkage pulleys 161 and the first transfer pulleys 1711. Since the rotation direction between the first transfer shaft 14, the first linkage shaft 16 and the first knife shaft 171 does not change, When the first active roller shaft 131 rotates, it drives the three first circular cutting knives 1712 to rotate in the opposite direction. At the same time, since the diameter of the first linkage pulley 161 is greater than the diameter of the first transfer pulley 1711, the first circular cutting knives 1712 are accelerated to enable the first circular cutting knives 1712 to rotate at a high speed. The three first swing arms 17 and the first flat support plate 111 are respectively connected with first tension springs 18. The first tension springs 18 make the first swing arms 17 have a tendency to swing upward. The bottom of the first flat support plate 111 is respectively fixed with first limit plates 1112 corresponding to the first swing arms 17. The first limit plates 1112 are used to limit the upper limit of the swing of the first swing arms 17. The first circular cutters 1712 are respectively provided with first avoidance grooves 1111 in their swinging range. When the first swing arm 17 is at its upper swinging limit position, the first circular cutters 1712 thereon can protrude above the first flat support plate 111 through the corresponding first avoidance grooves 1111. When the loading bag slides over the first circular cutters 1712, the first circular cutters 1712 are used to cut the bottom of the loading bag horizontally. The three first circular cutters 1712 can all swing elastically independently. On the one hand, this is to avoid hindering the sliding passage of the loading bag. On the other hand, this is to enable the three first circular cutters 1712 to adapt to the uneven bottom of the loading bag by themselves, so that each first circular cutter 1712 can effectively contact and cut the loading bag.

[0025] like Figure 5-Figure 7As shown, the second conveying mechanism 20 includes a second conveying frame 21, on which a second flat support plate 211 is fixedly provided, and on the second conveying frame 21, a second active roller shaft 231 is rotatably connected at one end in the conveying direction of the second conveying frame 21, and a second driven roller shaft 232 is rotatably connected at the other end, and two second conveying belts 233 arranged at intervals are transmission-connected between the second active roller shaft 231 and the second driven roller shaft 232, and the two second conveying belts 233 both surround the second flat support plate 211 from top to bottom, and a second motor 22 is provided on the second conveying frame 21, and the second motor 22 is used to drive the second active roller shaft 231 to rotate, thereby driving the two second conveying belts 233 to rotate, and the friction force of the two second conveying belts 233 can drive the loading bag above them to slide longitudinally on the second flat support plate 211, and the function of the second flat support plate 211 is also to prevent the loading bag from leaking materials from the incision at the bottom thereof, and a proximity switch 29 is provided at the conveying end of the second conveying frame 21, and the proximity switch 29 is electrically connected to the first motor 12 and the second motor 22 through a controller.

[0026] Furthermore, a second driving gear 2311 is fixedly connected to the second driving roller shaft 231, a second transfer shaft 24 is rotatably connected to the second conveyor frame 21, a second driven gear 241 is fixedly connected to the second transfer shaft 24, the second driving gear 2311 is meshed with the second driven gear 241, so that the second driving roller shaft 231 and the second transfer shaft 24 rotate in opposite directions, a second linkage shaft 26 is rotatably connected to the position below the second flat support plate 211 on the second conveyor frame 21, the second transfer shaft 24 and the second linkage shaft 26 are connected via a second belt transmission assembly 25, and the second linkage A second swing arm 27 is provided at the middle position of the shaft 26, one end of the second swing arm 27 is rotatably connected to the second linkage shaft 26, and the other end of the second swing arm 27 is rotatably connected to a second knife shaft 271, the axial direction of the second knife shaft 271 is perpendicular to the conveying direction of the second conveying mechanism 20, a second transfer pulley 2711 and a second circular cutter 2712 are fixedly connected to the second knife shaft 271, a second linkage pulley 261 is fixedly connected to the second linkage shaft 26, and a second linkage belt 262 is transmission-connected between the second linkage pulley 261 and the second transfer pulley 2711. The rotation direction between the driving shaft 26 and the second knife shaft 271 does not change, so when the second active roller shaft 231 rotates, it drives the second circular cutter 2712 to rotate in the opposite direction. At the same time, since the diameter of the second linkage pulley 261 is larger than the diameter of the second transfer pulley 2711, the second circular cutter 2712 is accelerated to achieve high-speed rotation of the second circular cutter 2712. A second tension spring 28 is connected between the second swing arm 27 and the second flat support plate 211. The second tension spring 28 makes the second swing arm 27 have a tendency to swing upward. A second limit spring 28 is fixedly provided at the bottom of the second flat support plate 211 corresponding to the second swing arm 27. The second limiting plate 2112 is used to limit the upper limit of the swing of the second swing arm 27. The second avoidance groove 2111 is provided on the second flat supporting plate 211 corresponding to the swing range of the second circular cutting knife 2712. When the second swing arm 27 is at its upper limit of swing, the second circular cutting knife 2712 thereon can protrude above the second flat supporting plate 211 through the corresponding second avoidance groove 2111. When the loading bag slides over the second circular cutting knife 2712, the second circular cutting knife 2712 is used to cut the bottom of the loading bag longitudinally. The second circular cutting knife 2712 can swing elastically to avoid hindering the sliding passage of the loading bag.

[0028] The hook bag assembly includes a driving sprocket shaft 371 and a driven sprocket shaft 372 which are vertically arranged along the conveying direction of the second conveying mechanism 20. The driving sprocket shaft 371 and the driven sprocket shaft 372 are rotatably connected to the top of the feeding frame 31, wherein the driving sprocket shaft 371 is located above the feeding hopper 32, and the driven sprocket shaft 372 is located above the end of the second flat support plate 211. Two driving sprockets 3711 are fixed on the driving sprocket shaft 371 at intervals, and two driven sprockets 3721 are fixed on the driven sprocket shaft 372 at intervals. A rotating chain 373 is connected between each of the two corresponding driving sprockets 3711 and the driven sprocket 3721. A plurality of connecting plates 374 are evenly installed between the two rotating chains 373. The two ends of each connecting plate 374 are rotatably connected to a push wheel 3741, and each connecting plate 374 The two rotating chains 373 are respectively connected with sliding rods 375 in a normal sliding manner, the normal outer ends of the sliding rods 375 are fixedly connected with hooks 3751, and the normal inner ends of the sliding rods 375 are rotatably connected with rollers 3752. A fixed plate 33 fixedly connected to the feeding frame 31 is provided between the two rotating chains 373, and a rotating groove 331 for the rollers 3752 to roll is provided on the fixed plate 33. A corrugated section 331 is provided at the bottom of the rotating groove 331. The active sprocket shaft 371 in the hook bag assembly is connected to the third adapter shaft 35 in the power assembly through a chain transmission assembly 36, so that the power assembly is used to drive the two rotating chains 373 to rotate synchronously, drive multiple connecting plates 374 and the sliding rods 375 thereon to make a rotating motion, and use the hooks 3751 on the sliding rods 375 to hook the loading bag at the end of the second conveying mechanism 20.

[0029] There are two groups of bag clamping assemblies, which are symmetrically arranged on both sides of one end of the hook bag assembly away from the second conveying mechanism 20. Each group of bag clamping assemblies includes a sliding frame 381 slidably connected to the feeding frame 31, and the sliding direction of the sliding frame 381 is perpendicular to the conveying direction of the second conveying mechanism 20. The bottom of the sliding frame 381 is rotatably connected with a driving pulley 382 and a driven pulley 383 along the vertical axis, wherein the driving pulley 382 is away from the hook bag assembly, and the driven pulley 383 is close to the hook bag assembly. A clamping belt 384 is transmission-connected between the driving pulley 382 and the driven pulley 383. The two clamping belts 384 in the two groups of bag clamping assemblies are distributed on both sides below the moving path of the multiple hooks 3751.

A clamping spring 386 is respectively provided between the two sliding frames 381 in the two groups of bag clamping assemblies and the feeding frame 31. The clamping spring 386 makes the sliding frame 381 have a tendency to slide inward, so that the two clamping belts 384 in the two groups of bag clamping assemblies have a tendency to move toward the middle. The two sliding frames 381 are respectively fixedly connected with a wedge-shaped push plate 3811 that cooperates with the push wheel 3741. When each connecting plate 374 passes between the two wedge-shaped push plates 3811, the push wheel 3741 is used to push the corresponding wedge-shaped push plate 3811 outward, so that the two clamping belts 384 in the two groups of bag clamping assemblies are separated by a certain distance.

[0030] The working principle of the automatic bag cutting and feeding system for bagged meat aggregates is as follows: The loading bag is first conveyed on the first conveying mechanism 10. Two first conveyor belts 133 in the first conveying mechanism 10 drive the loading bag above them to slide horizontally on the first flat pallet 111. During this period, three first circular cutting knives 1712 in the first conveying mechanism 10 transversely cut three incisions at the bottom of the loading bag. After the loading bag slides to the end of the first conveying mechanism 10, it slides down along the inclined chute 112 and then is thrown onto the second conveying mechanism 20 by inertia. Two second conveyor belts 233 in the second conveying mechanism 20 drive the loading bag to slide longitudinally on the second flat pallet 211. During this period, the second circular cutting knife 2712 in the second conveying mechanism 20 longitudinally cuts one incision at the bottom of the loading bag, forming a "feng" - shaped incision at the bottom of the loading bag. After the loading bag slides to the end of the second conveying mechanism 20, it blocks the proximity switch 29. The proximity switch 29 immediately transmits the induction signal to the controller, and the controller controls the first motor 12 and the second motor 22 to stop rotating, so that the first conveying mechanism 10 and the second conveying mechanism 20 pause working to prevent material accumulation. Until the hook - bag assembly in the feeding mechanism 30 takes away the loading bag at the end of the second conveying mechanism 20, after the shielding effect on the proximity switch 29 is eliminated, it transmits the induction signal to the controller again, and the controller controls the first motor 12 and the second motor 22 to start, so that the first conveying mechanism 10 and the second conveying mechanism 20 resume working.

[0031] The power component in the feeding mechanism 30 continuously works without interruption, driving the two rotary chains 373 in the hook-bag component to continuously rotate. During the rotary motion of the multiple connecting plates 374 between the two rotary chains 373 and the sliding rods 375 thereon, the hooks 3751 on the multiple sliding rods 375 sequentially and alternately pass above the end of the second conveying mechanism 20. After the hooks 3751 hook the loading bags at the end of the second conveying mechanism 20, they gradually drag the loading bags away from the second flat supporting plate 211, making the loading bags suspended above the feeding hopper 32. The loading bags discharge the meat and aggregate through the "Feng"-shaped cut thereon. As the rollers 3752 on the sliding rods 375 roll through the corrugated section 3311 in the rotary groove 331, the sliding rods 375 and the hooks 3751 perform up-and-down reciprocating motions, thereby generating a shaking effect on the loading bags, so as to ensure that all the meat and aggregate in the loading bags are discharged, avoiding the remaining meat and aggregate in the loading bags. The discharged meat and aggregate are received by the feeding hopper 32 and fall into the processing equipment. Subsequently, the connecting plate 374 rotates between the two wedge-shaped push plates 3811, and the push wheels 3741 at both ends of the connecting plate 374 respectively push the corresponding wedge-shaped push plates 3811 outwards, separating the two clamping belts 384 in the two clamping bag components by a certain distance, so as to facilitate the empty bags after being emptied to enter between the two clamping belts 384. At the same time, the driven end face ratchet 3852 on the transmission shaft 385 is axially separated from the driving end face ratchet 3411 on the power output shaft 341, interrupting the power of the clamping belt 384 and stopping its rotation, which is used to prevent the empty bags on the hooks 3751 from being pushed down by the clamping belt 384 before clamping. After the push wheel 3741 is separated from the wedge-shaped push plate 3811, the sliding frame 381 immediately slides inwards under the elastic force of the clamping spring 386, elastically closing the two clamping belts 384 to clamp the empty bags. At the same time, the driven end face ratchet 3852 on the transmission shaft 385 is gradually axially engaged with the driving end face ratchet 3411 on the power output shaft 341, and the transmission shaft 385随之 rotates synchronously with the power output shaft 341. Driven by the driving bevel gear 3851 and the driven bevel gear 3821, the driving belt pulley 382, the driven belt pulley 383 and the clamping belt 384 rotate. As can be seen from the attached drawings, in this embodiment, the number of teeth of the driving bevel gear 3851 is greater than that of the driven bevel gear 3821, and the diameters of the driving belt pulley 382 and the driven belt pulley 383 are greater than the diameters of the driving sprocket 3711 and the driven sprocket 3721. Therefore, the linear velocity of the clamping belt 384 is greater than the linear velocity of the rotary chain 373, so that the empty bags can be separated from the hooks 3751 under the drive of the two clamping belts 384 and then discharged from the rear of the feeding machine frame 31.
