In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0036] Embodiment 1:

[0037] like Figure 1 to Figure 7 As shown, this embodiment provides an automatic bag breaking and feeding device, including a main body 1 of the bag breaking and feeding device. A transmission belt 2 is fixedly installed on one side of the upper end of the main body 1. The transmission belt 2 is used to transport materials and is mostly used in factories. An electric saw 4 is fixedly installed on the other side of the upper end of the main body 1. The electric saw 4 is used to cut the package to achieve the purpose of breaking the bag. Among them, the electric saw 4 is preferably set to two, which can make the bag breaking efficiency higher.

[0038] In order to conveniently fix the electric saw 4, the upper end of the main body 1 is fixedly connected with a second bracket 12, and the upper end of the second bracket 12 is fixedly connected to one side of the electric saw 4 for fixing the electric saw 4. The upper end of the main body 1 is provided with a material guide mechanism 3 for moving the material packaging bag to the electric saw 4 for bag breaking.

[0039] The material guiding mechanism 3 comprises a rotating drum 31 , a mounting plate 32 , a shaking plate 33 and an insertion pin 34 . The upper end of the main body 1 is fixedly connected to the first bracket 11 , and the rotating drum 31 is rotatably mounted on the upper end of the first bracket 11 .

[0040] In order to facilitate the rotation of the drum 31 and to enable the materials in the package to be fully discharged after being broken by the electric saw 4, a shaking mechanism 7 is provided at the upper end of the first bracket 11. Figure 2 As shown, the shaking mechanism 7 includes a brushless motor 71, a hinge support 72 and a third elastic member 73. The brushless motor 71 is preferably a brushless AC reciprocating motor, which is fixedly connected to the upper end of the first bracket 11, and a reducer 74 is fixedly connected to the output shaft of the brushless motor 71.

[0041] Both ends of the rotating drum 31 are fixedly connected with rotating rods, which can facilitate the rotating drum 31 to rotate in the first bracket 11 . One end of the rotating rod of the rotating drum 31 is fixedly connected to a side of the reducer 74 away from the brushless motor 71 .

[0042] Preferably, the third elastic member 73 is configured as a spring and is sleeved and installed on the rotating rods at both ends of the rotating drum 31 to reduce shock to the rotating drum 31 and make the rotation of the rotating drum 31 more stable.

[0043] One end of the mounting plate 32 is fixedly connected to the outer wall of the rotating drum 31, and the mounting plate 32 is provided in plurality, and the plurality of mounting plates 32 are evenly arranged in a circular array and fixedly connected to the outer wall of the rotating drum 31. A groove is provided at one end of the mounting plate 32 away from the rotating drum 31, and a hinge support 72 is fixedly installed in the mounting plate 32. One end of the shaking plate 33 is hinged on the hinge support 72, and the shaking plate 33 is conveniently rotated in the groove of the mounting plate 32 through the hinge support 72. A plurality of sliding holes are provided at one end of the shaking plate 33 away from the rotating drum 31, and a plurality of pins 34 are provided, and the plurality of pins 34 are respectively slidably installed in the plurality of sliding holes.

[0044] When the drum 31 rotates and the mounting plate 32 is close to the transmission belt 2 and flush with the transmission belt 2, the pin 34 slides out from the slide hole and is inserted into the material packaging bag on the transmission belt 2. At this time, the drum 31 continues to rotate, and the material packaging bag can be driven to rotate through the pin 34, and the material packaging bag is rotated to the electric saw 4 to cut the packaging bag and break the bag.

[0045] When the material packaging bag is broken, the brushless motor 71 performs reciprocating motion, and the reducer 74 causes the drum 31 to reciprocate, with a rotation angle of 1-5 degrees. The reciprocating rotation causes the drum 31 to vibrate, causing one end of the shaking plate 33 to swing back and forth in the mounting plate 32, thereby allowing the material in the broken material packaging bag to be discharged more comprehensively.

[0046] The main body 1 is provided with a first discharge port 13 and a second discharge port 14 for receiving materials and discharging material packaging bags. The first discharge port 13 is located below the material guide mechanism 3, and the discharge port of the first discharge port 13 is located on the side of the main body 1, and the second discharge port 14 is located below the electric saw 4, and the discharge port of the second discharge port 14 is located at one end of the main body 1.

[0047] In order to facilitate the collection of materials from the discharge port of the second discharge port 14, a receiving funnel 8 is fixedly installed on one side of the main body 1. The receiving funnel 8 is fixed on one side of the main body 1 and is lower than the discharge port of the second discharge port 14, so that the materials discharged from the discharge port of the second discharge port 14 fall into the receiving funnel 8. The receiving funnel 8 is used to be fixedly connected above the feed port of the material production device, and the material can fall from the receiving funnel 8 into the material storage device by its own gravity. The material production device includes an injection molding machine, a die-casting machine, etc.

[0048] A control mechanism 5 is provided in the shaking plate 33 for controlling the movement of the insertion pin 34 in the sliding hole. The control mechanism 5 comprises a winding roller 51, a pull rope 52 and a first elastic member 53. The winding roller 51 is movably mounted in the sliding hole of the shaking plate 33. One end of the pull rope 52 is fixedly connected to one end of the insertion pin 34, and the other end of the pull rope 52 is fixedly connected to the outer wall of the winding roller 51. By rotating the winding roller 51 to reel the pull rope 52 on the winding roller 51, the insertion pin 34 can be pulled to slide and retract into the sliding hole by reeling in the pull rope 52.

[0049] In order to facilitate the extension of the insertion pin 34, a first elastic member 53 is fixedly installed in the sliding hole. Among them, a limit plate 331 is fixedly installed in the sliding hole of the shaking plate 33. The limit plate 331 is used to separate the winding roller 51 and the insertion pin 34. The limit plate 331 is provided with a through hole, and the pull rope 52 passes through the through hole. The first elastic member 53 is preferably set as a spring, and one end of the first elastic member 53 is fixedly connected to one side of the limit plate 331, and the other end of the first elastic member 53 is fixedly connected to one end of the insertion pin 34. The first elastic member 53 provides an elastic force toward the opening of the sliding hole to the insertion pin 34, and then the elastic force of the first elastic member 53 pops out the insertion pin 34 and inserts it into the packaging bag.

[0050] In order to conveniently control the rotation of the winding roller 51, a driving motor 54 is fixedly installed in the shaking plate 33. The driving motor 54 is preferably a servo motor, and one end of the output shaft of the driving motor 54 is fixedly connected to a sleeve 542, and the output shaft of the driving motor 54 is fixedly sleeved with a first rotating disk 543, and the winding roller 51 is slidably sleeved on the sleeve 542.

[0051] Among them, a clamping block 541 is fixedly connected to the side of the first turntable 543 facing the winding roller 51, and a plurality of clamping holes 511 are opened at the end of the winding roller 51 facing the first turntable 543. The clamping holes 511 are evenly arranged in a circular array on one side of the winding roller 51. By sliding the winding roller 51 on the sleeve 542 and making the clamping block 541 engage in the clamping hole 511, the winding roller 51 can be fixedly connected to the first turntable 543. Then, when the driving motor 54 is turned on, the winding roller 51 is driven to rotate through the first turntable 543.

[0052] When the winding roller 51 slides on the outer wall of the sleeve 542 away from the first turntable 543, the block 541 is disengaged from the hole 511. At this time, the winding roller 51 can rotate autonomously in the sliding hole of the shaking plate 33. After the pin 34 is popped out by the elastic force of the first elastic member 53, the pull rope 52 can drive the winding roller 51 to rotate.

[0053] The swing plate 33 is provided with a sliding mechanism 6 for making the winding roller 51 slide on the outer side wall of the sleeve 542. The sliding mechanism 6 includes a second elastic member 61 and a first cam 62. The first cam 62 is rotatably mounted in the swing plate 33. The second elastic member 61 is preferably a spring. The second elastic member 61 is sleeved and mounted on the outer side wall of the sleeve 542. The second elastic member 61 is located between the first rotating disk 543 and the winding roller 51, and is used to provide elastic force to the winding roller 51 so that the winding roller 51 is away from the first rotating disk 543.

[0054] In order to facilitate the winding roller 51 to rotate on one side of the second elastic member 61 and cause the winding roller 51 to wear, a second rotating disk 611 is fixedly connected to one end of the second elastic member 61. The second rotating disk 611 is slidably sleeved on the outer wall of the sleeve 542. A third rotating disk 63 is slidably installed on one side of the sleeve 542, wherein a sliding rod 631 is fixedly connected to one end of the third rotating disk 63, and a sliding groove is provided at one end of the sleeve 542. The sliding rod 631 is slidably inserted in the sliding groove of the sleeve 542, and the sliding rod 631 slides in the sliding groove, thereby causing the third rotating disk 63 to slide on one end of the sleeve 542.

[0055] The first cam 62 is rotatably installed on one side of the third turntable 63, and the outer wall of the first cam 62 is in contact with the third turntable 63. After the first cam 62 rotates, the outer wall farthest from the center of rotation drives the third turntable 63 to slide toward the drive motor 54, and then the winding roller 51 is pushed toward the drive motor 54 through the third turntable 63, so that the block 541 is engaged in the hole 511.

[0056] The lower end of the first cam 62 is fixedly connected with a driven gear 621 for driving the first cam 62 to rotate. A driving gear 64 is rotatably installed in the shaking plate 33, and a motor for driving the driving gear 64 to rotate is fixedly installed in the shaking plate 33. The driving gear 64 is fixedly connected to the output shaft of the motor, and the driving gear 64 is driven to rotate by the motor. The driven gear 621 meshes with the driving gear 64, and the rotation of the driving gear 64 drives the driven gear 621 to rotate, thereby driving the first cam 62 to rotate.

[0057] The second turntable 611 and the third turntable 63 preferably adopt plane ball bearings, and the second turntable 611 and the third turntable 63 facilitate the rotation of the winding roller 51.

[0058] The present embodiment provides an automatic bag breaking and feeding device, which fixes the material packaging bag by means of a pin 34, drives the mounting plate 32 to rotate by rotating the rotating drum 31, and moves the material packaging bag to the electric saw 4 for cutting and bag breaking, so that the material flows out for collection. The rotating drum 31 is rotated to make the mounting plate 32 vertically downward and retract the pin 34, so that the emptied material packaging bag can fall downward by its own gravity for collection, thereby solving the problem of the existing material bag breaking device that after the material leaks out of the opening of the material packaging bag, the shriveled material packaging bag is easily dropped and collected together with the material.

[0059] Embodiment 2:

[0060] As shown in the figure, this embodiment provides an automatic bag breaking and feeding method, which adopts the automatic bag breaking and feeding device as described in Example 1, and includes the following steps:

[0061] The material packaging bag is moved to the material guide mechanism 3 by the transmission belt 2, and the rotating drum 31 rotates to make the mounting plate 32 close to the transmission belt 2. At this time, the pin 34 in the material guide mechanism 3 is ejected by the control mechanism 5, which specifically includes:

[0062] When the groove of the mounting plate 32 faces the transmission belt 2, the winding roller 51 is driven to rotate by the driving motor 54, so that the pull rope 52 is scattered from the winding roller 51, and then the insertion pin 34 is ejected by the first elastic member 53. The insertion pin 34 slides out from the sliding hole and is inserted into the material packaging bag on the transmission belt 2. At this time, the rotating drum 31 drives the insertion pin 34 to rotate continuously, and the material packaging bag is rotated to the electric saw 4 through the insertion pin 34 to break the bag;

[0063] When the material packaging bag is broken, the brushless motor 71 performs reciprocating motion, and the reducer 74 causes the drum 31 to reciprocate, with a rotation angle of 1-5 degrees. The reciprocating rotation causes the drum 31 to vibrate, causing one end of the shaking plate 33 to swing back and forth in the mounting plate 32, thereby allowing the material in the broken material packaging bag to be discharged more comprehensively.

[0064] After the material in the material packaging bag is completely discharged, the rotating drum 31 continues to rotate until the mounting plate 32 is vertically downward, and the groove notch of the mounting plate 32 is downward, and the pin 34 is retracted into the shaking plate 33 through the control mechanism 5; specifically, the winding roller 51 is rotated in the reverse direction, and the pull rope 52 is rolled up to retract the pin 34 into the shaking plate 33.

[0065] At this time, the broken material packaging bag can fall to the first discharge port 13 by its own gravity.

[0066] The present embodiment provides an automatic bag breaking and feeding method, in which a pin 34 is extended from one end of a shaking plate 33 and inserted into a material packaging bag to fix the material packaging bag, and then the mounting plate 32 is driven to rotate by rotating the rotary drum 31, and the material packaging bag is moved to the electric saw 4 for cutting and bag breaking, so that the material flows out for collection, and then the rotary drum 31 is rotated to make the mounting plate 32 move vertically downward, and at this time the pin 34 is retracted, so that the empty material packaging bag can fall downward under its own gravity for collection, thereby solving the problem of the existing material bag breaking device that after the material leaks out of the opening of the material packaging bag, the shriveled material packaging bag is easily dropped and collected together with the material.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
