The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0048] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] A self-sealing bag feeding machine, such as Figure 1 As shown, it includes a frame 9, on which are arranged: a bag rack 1 for placing a ziplock bag 8; a bag taking and opening assembly 2, including a bag taking suction cup 201 and a bag opening suction cup 202, the bag taking suction cup 201 is rotatably connected to the frame 9, and is used to take the ziplock bag 8 off the bag rack 1, when the bag taking suction cup 201 drives the ziplock bag 8 to rotate toward the bag opening suction cup 202, the bag taking suction cup 201 and the bag opening suction cup 202 are respectively sucked on both sides of the opening of the ziplock bag 8 to open the ziplock bag 8, so that the material can fall into the ziplock bag 8; a bag moving assembly 3, which is slidably connected to the frame 9, and includes two adjustable The two clamping jaws 301 are respectively clamped at the two ends of the ziplock bag 8. When the bag taking and opening assembly 2 opens the ziplock bag 8, the distance between the two clamping jaws 301 is reduced; the bag sealing assembly 4 is arranged on the moving path of the bag moving assembly 3, and includes a fixed wheel 401 and a movable wheel 402. When the material falls into the ziplock bag 8, the bag moving assembly 3 drives the ziplock bag 8 to pass through the middle of the fixed wheel 401 and the movable wheel 402. The fixed wheel 401 and the movable wheel 402 are clamped on both sides of the opening of the ziplock bag 8 to close the opening; the discharging assembly 7 is used to transport the ziplock bag 8 after the opening is closed.

[0050] like Figures 2 to 4 As shown, the bag taking and opening assembly 2 includes a vertically arranged bag taking drive rod 203, and a rotating motor for driving the bag taking drive rod 203 is connected to the bag taking drive rod 203, and the rotating motor is directly connected to the top of the bag taking drive rod 203, driving the bag taking drive rod 203 to rotate in situ, and a mounting frame 204 is fixed on the peripheral side wall of the bag taking drive rod 203, and a bag taking cylinder 205 is fixed on the top of the mounting frame 204, and the piston rod of the bag taking cylinder 205 is perpendicular to the bag taking drive rod 203, and a first mounting plate 206 is fixed on the piston rod of the bag taking cylinder 205, and the first mounting plate 206 is vertically arranged, and the bag taking suction cup 201 is fixed on the first mounting plate 206. Specifically, four bag taking suction cups 201 are arranged in a rectangular shape, and an adjustment hole is opened on the first mounting plate 206 extending along its width direction, and the bag taking suction cups 201 are fixed in the adjustment hole by screws, and the spacing between the bag taking suction cups 201 can be adjusted through the adjustment hole to be suitable for self-sealing bags 8 of different sizes.

[0051] A stroke limiting cylinder 207 is also fixed to the bottom of the mounting frame 204. The extension and retraction direction of the piston rod of the stroke limiting cylinder 207 is the same as that of the bag taking cylinder 205, and the extended length of the piston rod of the stroke limiting cylinder 207 is less than the extended length of the piston rod of the bag taking cylinder 205, generally half of the extended length of the piston rod of the bag taking cylinder 205. When the piston rod of the bag taking cylinder 205 retracts, the first mounting plate 206 abuts against the piston rod of the stroke limiting cylinder 207, so that the piston rod of the bag taking cylinder 205 cannot continue to retract, thereby limiting the moving distance of the bag taking suction cup 201, and preventing the ziplock bag 8 from being torn off the suction cup 201 when opening the bag.

[0052] The bag taking and opening assembly 2 also includes a bag opening cylinder 208 fixed on the frame 9, a second mounting plate 209 is fixed on the piston rod of the bag opening cylinder 208, and a bag opening suction cup 202 is fixed on the second mounting plate 209. There are two bag opening suction cups 202, and the second mounting plate 209 is also provided with an adjustment hole. The bag opening suction cups 202 are locked on the adjustment hole by screws, and the spacing can be adjusted to be suitable for self-sealing bags 8 of different sizes. The bag taking cylinder 205 is extended to make the four The bag taking suction cups 201 are respectively sucked on the four corners of the ziplock bag 8, and then the bag taking driving rod 203 rotates 90° to make the bag taking suction cups 201 face the direction of the bag opening suction cups 202, and the bag opening cylinder 208 extends to make the bag opening suction cups 202 sucked on the other side of the ziplock bag 8. At this time, the two bag taking suction cups 201 below are released, and when the bag taking cylinder 205 and the bag opening cylinder 208 retract, the bag taking suction cups 201 and the bag opening suction cups 202 can open the opening of the ziplock bag 8.

[0053] like Figures 5 to 7 As shown, the bag moving assembly 3 includes a linear guide rail 302 arranged on the frame 9, the linear guide rail 302 is located between the bag opening cylinder 208 and the bag taking drive rod 203, and a bag moving bracket 303 is slidably connected to the linear guide rail 302. A bag moving motor for driving the bag moving bracket 303 to move along the linear guide rail 302 is also installed on the frame 9. The bag moving motor drives the bag moving bracket 303 through a belt, and two clamps 301 are arranged on the bag moving bracket 303.

[0054] The bag transfer bracket 303 is provided with an adjustment rail 304, which is parallel to the linear guide rail 302. Two adjustment blocks 305 are slidably connected to the adjustment rail 304. An adjustment motor 306 for driving the adjustment blocks 305 to move along the adjustment rail 304 is installed on the bag transfer bracket 303. The adjustment motor 306 drives the two adjustment blocks 305 to move through the screw 307, and the two adjustment blocks 305 move toward each other or move away from each other. The two clamping claws 301 are respectively rotatably connected to the ends of the adjustment blocks 305, and the bag taking drive rod 203 rotates 90° to make the bag taking suction cup 201 face the bag opening suction cup 202. When the ziplock bag 8 is in the direction, it is attached to the end of the adjusting block 305. At this time, the clamping jaw 301 rotates inward, thereby clamping the ziplock bag 8 at the end of the adjusting block 305. The adjusting block 305 is provided with a clamping drive cylinder 308. The piston rod of the clamping drive cylinder 308 is connected to the clamping jaw 301 through a connecting rod 309, thereby driving the clamping jaw 301 to rotate. Both ends of the connecting rod 309 are rotatably connected, and the rear end of the clamping drive cylinder 308 is rotatably connected to the adjusting block 305. A tensioning block 310 is also connected between the piston rod of the clamping drive cylinder 308 and the adjusting block 305, and both ends of the tensioning block 310 are rotatably connected.

[0055] When the bag taking suction cup 201 and the bag opening suction cup 202 move to both sides to open the opening of the ziplock bag 8, the adjustment motor 306 drives the two adjustment blocks 305 to move toward each other, so that the clamping jaws 301 clamp the two ends of the ziplock bag 8 close to each other, to prevent the ziplock bag 8 from falling off the bag taking suction cup 201 and the bag opening suction cup 202 due to the opening of the ziplock bag 8 being opened outward.

[0056] like Figure 8 As shown, the rotating shafts of the fixed wheel 401 and the movable wheel 402 are both vertically arranged, the fixed wheel 401 is fixedly connected to the frame 9 and can only rotate in situ, a bag sealing bracket 403 is fixed to the frame 9, a movable block 404 is rotatably connected to the bag sealing bracket 403, the movable wheel 402 is fixed to the movable block 404, a steel sheet is fixed to the bag sealing bracket 403, a through hole 405 is extended along the moving direction of the bag moving component 3 on the steel sheet, and the movable block 404 passes through the through hole 405 The support rod is provided with a reset spring 406. When the reset spring 406 is in the initial state, the movable wheel 402 is in contact with the fixed wheel 401. When the bag moving assembly 3 drives the ziplock bag 8 to pass through the middle of the movable wheel 402 and the fixed wheel 401, the movable wheel 402 is pushed outward. At the same time, the reset spring 406 provides thrust for the movable wheel 402, so that the fixed wheel 401 and the movable wheel 402 are respectively pressed against the two sides of the opening. After the ziplock bag 8 passes through, the self-sealing strip at the opening is closed to complete the bag sealing.

[0057] like Fig. 9 As shown, a blanking assembly 5 is also provided on the frame 9, and the blanking assembly 5 includes a blanking cylinder 501 and a blanking bracket 502 connected to the piston rod of the blanking cylinder 501. The blanking cylinder 501 drives the blanking bracket 502 to move in the vertical direction, and an openable and closable blanking channel is provided on the blanking bracket 502. When the blanking cylinder 501 drives the blanking channel to move downward and extend into the ziplock bag 8, the blanking channel opens, and the material falls into the ziplock bag 8 along the blanking channel, which guides the material and prevents the material from falling outside the ziplock bag 8.

[0058] The material blanking channel includes a side baffle plate 503 and a surrounding baffle plate 504 which are rotatably connected to the material blanking bracket 502. The two ends of the top of the material blanking bracket 502 are respectively provided with a channel cylinder 505 for driving the side baffle plates 503 and the surrounding baffle plates 504 to rotate. When the material blanking cylinder 501 drives the material blanking channel to move downward and extend into the ziplock bag 8, the side baffle plates 503 and the surrounding baffle plates 504 are tightly fitted and closed below each other, making it easier to extend into the ziplock bag 8. After extending, the side baffle plates 503 and the surrounding baffle plates 504 are opened outward below, and the material conveyor belt feeds the material from the side away from the surrounding baffle plate 504, and a detection sensor 506 is arranged behind the surrounding baffle plate 504, and a detection hole is opened on the surrounding baffle plate 504 for the laser emission of the detection sensor 506 to detect whether there is more material falling from the material blanking channel.

[0059] like Figures 10 to 12 As shown, a bag holding assembly 6 is also arranged on the frame 9 and below the blanking assembly 5. The bag holding assembly 6 includes a vertically arranged bag holding guide rail 601, a bag holding bracket 602 is slidably connected to the bag holding guide rail 601, and also includes a bag holding motor 603 for driving the bag holding bracket 602 to move. The bag holding motor 603 drives the bag holding bracket 602 to slide on the bag holding guide rail 601 through a synchronous belt. Two openable and closable bag holding rollers 604 are arranged on the bag holding bracket 602. The bag holding bracket 602 is also provided with a bag holding roller 604 for driving the bag holding bracket 602. The bag supporting cylinder 605 opens and closes the bag roller 604. When the bag taking drive rod 203 rotates 90 degrees to make the bag taking suction cup 201 face the bag opening suction cup 202, the bag supporting motor 603 drives the bag supporting bracket 602 to move upward, so that the bottom of the ziplock bag 8 passes through between the two bag supporting rollers 604. When the material is filled, as the material in the ziplock bag 8 increases, the bag supporting bracket 602 will gradually move downward. When the material is filled, the bag moving component 3 needs to drive the ziplock bag 8 to move away, and the bag supporting cylinder 605 drives the two bag supporting rollers 604 to open outward.

[0060] The two bag supporting rollers 604 are rotatably connected to the bag supporting bracket 602 through connecting plates 606 respectively. The connecting plate 606 on the outer bag supporting roller 604 extends downward to be rotatably connected to the piston rod of the bag supporting cylinder 605. At the same time, a tensioning rod 607 is connected between the downward extending part of the connecting plate 606 of the outer bag supporting roller 604 and the connecting plate 606 of the inner bag supporting roller 604. The rear end of the bag supporting cylinder 605 is rotatably connected to the bag supporting bracket 602. When the bag supporting cylinder 605 extends outward, the outer bag supporting roller 604 rotates inward. Under the action of the tensioning rod 607, the inner bag supporting roller 604 also rotates inward. When the bag supporting cylinder 605 retracts inward, the outer bag supporting roller 604 rotates outward, and the inner bag supporting roller 604 also rotates outward to achieve opening.

[0061] like Fig.13 As shown, the discharging assembly 7 includes a discharging conveyor belt 701 and a lifting cylinder 702. The discharging conveyor belt 701 is rotatably connected to the frame 9, and the lifting cylinder 702 is vertically arranged below the discharging conveyor belt 701. When the piston rod of the lifting cylinder 702 is extended, one end of the discharging conveyor belt 701 is lifted up, thereby driving the discharging conveyor belt 701 to rotate. The discharging conveyor belt 701 is located below the bag transfer assembly 3. Initially, the lifting cylinder 702 extends to lift the discharging conveyor belt 701 to reduce the height difference between the material and the conveyor belt. After the material falls on the discharging conveyor belt 701, the lifting cylinder 702 retracts, and the discharging conveyor belt 701 rotates back to a horizontal state to deliver the material.

[0062] like Figure 1 and Fig.14As shown, two bag racks 1 are arranged on the frame 9 of this embodiment, and the two bag racks 1 are respectively arranged on both sides of the bag taking drive rod 203. The bag taking drive rod 203 can drive the bag taking suction cup 201 to rotate toward the bag rack 1 on either side. When the ziplock bags 8 on one bag rack 1 are completely taken out, the bag taking suction cup 201 rotates to the bag rack 1 on the other side to take the bags. The two bag racks 1 can be used alternately, and there is no need to stop the machine for replenishing materials, thereby improving work efficiency.

[0063] An inclined placing rod 101 is provided on the bag rack 1, and the ziplock bag 8 is placed on the placing rod 101. The placing rod 101 can be adjusted in height in the vertical direction by a screw rod provided on the bag rack 1. The front end of the placing rod 101 is horizontally arranged to prevent the ziplock bag 8 at the front end from slipping. A detection sensor 506 is also provided on the mounting frame 204. If the detection sensor 506 emits a laser to detect that the ziplock bag 8 on the bag rack 1 has been taken out, the bag taking drive rod 203 drives the bag taking suction cup 201 to rotate to the bag rack 1 on the other side to take the bag.

[0064] The working process of the utility model is as follows:

[0065] After the bag taking suction cup 201 sucks the ziplock bag 8, it rotates 90° to the position facing the bag opening suction cup 202. The clamping jaws 301 of the bag moving assembly 3 clamp the two ends of the ziplock bag 8. The bag taking cylinder 205 and the bag opening cylinder 208 shrink to open the bag. At the same time, the distance between the two clamping jaws 301 shrinks. After the bag is opened, the blanking assembly 5 is inserted into the bag and opens to start blanking. After blanking is completed, the distance between the clamping jaws 301 of the bag moving assembly 3 is expanded and restored to the initial state. The bag moving assembly 3 moves toward the discharge conveyor belt 701. During the movement, the bag sealing assembly 4 seals the ziplock bag 8. After the bag moving assembly 3 moves above the conveyor belt, the clamping jaws 301 open, and at this time, the lifting cylinder 702 extends to lift the discharge conveyor belt 701 to reduce the distance between it and the material. After the material falls to the discharge conveyor belt 701, the lifting cylinder 702 retracts, and the discharge conveyor belt 701 rotates to a horizontal state to deliver the material.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
