Description

Technical Field

[0001] The invention relates to a bag-feeding type packaging machine capable of performing horizontal bag-feeding. Background Art

[0002] Bag-feeding packaging machines are used for bag-feeding packaging of various materials and are widely used in the market. At present, bag-feeding packaging machines basically adopt a disc indexing rotation structure, and there are few packaging stations that can be set on the disc (basically eight or ten stations). If more packaging stations are to be set or two bags are to be packed at the same time, when the bag width is wider, the circumference of the disc will be very large, not only the size of the packaging machine equipment is large, but also due to inertia, the rotation speed of the disc will be very slow, which is not conducive to the improvement of packaging production speed. In addition, the current bag-feeding packaging machines all adopt vertical bag-feeding and top-feeding methods, which are not suitable for many materials (such as materials loaded on trays), and there are many differences in the action structure between horizontal bag-feeding and horizontal feeding methods and vertical bag-feeding and top-feeding methods, which need to be solved by the applicant to carry out efficient packaging production. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a circular horizontal bag packaging machine with compact structure and size, which is specially used for horizontal bag packaging and can have more packaging stations to realize efficient packaging production of two or even multiple bags at the same time.

[0004] The present invention is implemented by the following technical solutions:

[0005] The annular horizontal bag-feeding packaging machine is characterized in that it includes chain links running along a horizontal annular track, machine clamp components are installed on the chain links, each machine clamp component corresponds to a packaging station, the machine clamp component has a machine clamp plate and left and right machine clamps, the machine clamps are used to clamp horizontal bags, the machine clamps are swingably arranged on the machine clamp plate, the machine clamp plate is fixedly installed on the chain links, the machine clamps are connected to the swinging rollers, the horizontal annular track is provided with a curved groove to guide the swinging rollers to roll so that the left and right machine clamps are close to or away from each other, and a bag loading position and a horizontal feeding position are arranged outside the horizontal annular track, and the bag loading position is provided with a bag loading component and a clamping component.

[0006] The horizontal bag feeding packaging machine of the above technical solution, since the chain links for installing the machine clamp components are arranged in a ring shape, the machine clamp components can be arbitrarily arranged according to needs as long as the length of the ring track is reasonably increased, and more packaging stations corresponding to the machine clamp components can be arranged. In this way, for multiple packaging stations or simultaneous packaging production of two or even multiple bags, no matter how large the bag width is, the production requirements can be met as long as the spacing of the machine clamp components is designed in advance. The structural size of the packaging machine equipment is compact and the speed is not affected. Moreover, the circular movement process of the entire machine clamp component is carried out in a horizontal bag clamping manner, so the horizontal bag feeding packaging production can be well completed.

[0007] Preferably, the upper bag component includes a fixed bag bin, which is used for stacking and storing horizontal bags. A suction nozzle is provided at the bottom of the bag bin, which is installed on a suction nozzle seat. The suction nozzle seat is movably arranged up and down and flipped to the side at the lower limit position. A dynamic clamp and a static clamp are provided at the middle stop position of the suction nozzle. The dynamic clamp and the static clamp are used to clamp the horizontal bag sucked by the suction nozzle. The dynamic clamp and the static clamp are installed on the clamp seat, and the clamp seat is flipped 180 degrees. The suction nozzle seat can be flipped and connected to the vertical slide seat. The vertical slide seat can be movably arranged up and down on the vertical slide rail. The inner side of the vertical slide rail is parallel to a vertical guide groove. The bottom of the vertical guide groove is connected to the arc groove. The center of the arc groove is installed with a steering pin. The suction nozzle seat is provided with a steering pin guide groove and a guide roller. The guide roller rolls in the vertical guide groove and the arc groove. The clamp seat is connected to the flip shaft. The flip shaft is rotatably arranged on the fixed bracket of the bag bin. A gear is installed on the flip shaft. The gear is meshed with the vertical rack. The vertical rack is movably arranged up and down.

[0008] After adopting the above technical scheme, the bag loading component sucks the packaging bag from the bottom of the bag bin with the suction nozzle, and the dynamic clamp and the static clamp transfer and clamp the packaging bag sucked by the suction nozzle. The suction nozzle flips to the side with the suction nozzle seat to make way, and the clamp seat flips 180 degrees to send the packaging bag clamped by the dynamic clamp and the static clamp to the clamping mouth position of the left and right machine clamps in a horizontal state. Finally, the packaging bag is clamped by the clamping mouths of the left and right machine clamps. The whole bag loading process not only remains fast, but also the position of the packaging bag will not be offset or shifted, ensuring accurate and fast bag loading and achieving efficient production.

[0009] As a preferred embodiment, the clamping component includes a clamping control plate and a support roller. The clamping control plate is movable up and down and is pushed by a swing crank. The clamping control plate opens the clamp by pushing the clamping roller provided on the clamp. The support roller is arranged to roll closely on the front of the clamping plate. The support roller is installed on a roller seat. The roller seat is movable up and down and is pushed by a swing crank. The roller seat is guided up and down by a fixed roller frame. Through the above design, when the clamping control plate pushes the clamping roller to open the clamp, the support roller will move down to a position closer to the bottom on the front of the clamping plate, strengthen the rigidity of the clamping plate, ensure that the clamping action is more stable and reliable, and realize efficient production. This is because only the upper part of the clamping plate is fixed on the chain plate, and the lower part is suspended. The clamping of the left and right clamps needs to overcome a large spring force, that is, the clamping control plate must have a large downward thrust on the clamping roller when performing the clamping action, which easily causes the deformation and shaking of the clamping plate.

[0010] Preferably, a movable bag opening component is provided between the upper bag position and the horizontal feeding position. The movable bag opening component is provided with a slide plate, which moves synchronously with the machine clamping plate during the bag opening process. When the slide plate moves, the suction cup of the movable bag opening component opens the bag mouth of the horizontal bag. A positioning pin is provided on the slide plate, and a positioning pin hole is provided on the machine clamping plate. At the starting position of the movement of the slide plate, the positioning pin is inserted into the positioning pin hole. At the end position of the movement of the slide plate, i.e., the horizontal feeding position, the positioning pin exits the positioning pin hole. The slide plate is pushed back to its original position after synchronous movement with the machine clamping plate by the slide plate cylinder. The movable bag opening component includes upper and lower suction cups, the upper suction cup is arranged to move up and down on the slide plate, the upper roller is provided at the end of the mounting rod of the upper suction cup, and the upper roller is arranged to roll on the upper guide plate, the lower suction cup is arranged to move up and down on the slide plate, the lower roller is provided at the end of the mounting rod of the lower suction cup, and the lower roller is arranged to roll on the lower guide plate, the upper guide plate and the lower guide plate are fixed on the baffle plate in front of the slide plate, the baffle plate is fixedly installed on the workbench, and a transverse slide rail is provided on the inner side of the baffle plate to guide the movement of the slide plate.

[0011] After adopting the above technical scheme, the mobile bag opening component performs the bag opening action as follows: during the movement of the machine clamp from leaving the bag loading position to the horizontal feeding position, due to the curve change of the curved groove provided on the horizontal annular track, the swinging roller will cause the left and right machine clamps to swing closer to each other, the distance between the clamping mouths of the left and right machine clamps becomes smaller, and the previously closed bag opening of the horizontal bag is slowly released. At the same time, the upper and lower suction cups of the bag opening component respectively suck and pull the bag opening of the horizontal bag open to open the bag opening. In the above bag opening process, the bag opening of the horizontal bag is gradually opened during the movement of the machine clamp, so the horizontal feeding action can be performed immediately after reaching the horizontal feeding position, thereby realizing efficient packaging production; in addition, since the slide plate on which the upper and lower suction cups are installed moves synchronously with the machine clamp in the above process, the relative position displacement between the upper and lower suction cups and the machine clamp during the moving bag opening process is avoided, which affects the normal opening and wrinkling of the bag opening of the packaging bag.

[0012] Preferably, a bag-supporting component is provided at the horizontal feeding position, and the bag-supporting component includes a bag-supporting frame and left and right bag-supporting rods, and the left and right bag-supporting rods are connected to left and right movable plates, and the left and right movable plates move relatively close to and away from each other in the bag-supporting frame, and the movement of the left and right movable plates is driven by a screw nut structure driven by a bag-supporting motor, and the bag-supporting frame is arranged to move forward and backward. The action process of the bag-supporting component is: when the horizontal bag with the bag opening opened reaches the horizontal feeding position, if the bag-supporting operation is required, the bag-supporting frame moves forward, and at the same time, the bag-supporting motor works to make the left and right bag-supporting rods inserted into the bag opening of the horizontal bag move away from each other, and the bag opening is expanded from left to right to facilitate horizontal feeding.

A positioning pin hole 14 is provided on the machine clamping plate 13. The left and right machine clamps 15 are used for clamping horizontal bags. The left and right machine clamps 15 are swingably arranged on the machine clamp The plate 13 is pulled by a tension spring, the right machine clamp is connected to the swing roller 16, the machine clamp 15 is provided with a clamping roller 17, the horizontal annular track 4 is provided with a curved groove to guide the swing roller 16 to roll so that the left and right machine clamps are close to or away from each other, and the horizontal annular track 4 is provided with a bag-loading position, a horizontal feeding position and a heat-sealing position. The bag-loading position is provided with a bag-loading component 2 and a clamping component 5. A movable bag-opening component 7 is provided between the bag-loading position and the horizontal feeding position, and a bag-supporting component 6 is provided at the horizontal feeding position. A fixed baffle 8 is provided on the outside of the movable bag-opening component 7, and a heat-sealing component 9 is provided at the heat-sealing position.

[0031] like Figure 7-11 As shown, the upper bag component 2 includes a fixed bag bin 21, which is used for stacking and storing horizontal bags A in an upper and lower manner. A suction nozzle 24 is provided at the bottom of the bag bin 21, and the suction nozzle 24 is installed on a suction nozzle seat 27. The suction nozzle seat 27 is arranged to be movable up and down and flipped to the side at the lower limit position. The specific structure is: the suction nozzle seat 27 is flippably connected to the vertical slide 28 through a rotating shaft 33, and the vertical slide 28 is movable up and down on the vertical slide rail 31. The vertical slide 28 is connected to the vertical pull rod 29, and the vertical pull rod 29 is pushed by the vertical cylinder 30 to move up and down. A vertical guide groove 32 is provided parallel to the inner side of the vertical slide rail 31, and the bottom of the vertical guide groove 32 is connected to the arc groove 39. The center of the arc groove 39 is fixedly installed with a steering pin 38, and the suction nozzle seat 27 is provided with a steering pin introduction groove 37 and a guide roller 40, and the guide roller 40 can roll in the vertical guide groove 32 and the arc groove 39. A dynamic clamp 25 and a static clamp 26 are provided at the middle stop position of the suction nozzle 24. The dynamic clamp 25 and the static clamp 26 are used to transfer and clamp the horizontal bag A sucked by the suction nozzle 24. The dynamic clamp 25 and the static clamp 26 are installed on the clamp seat 35. The movement of the dynamic clamp 25 is driven by the dynamic clamp cylinder 41. The clamp seat 35 is set to be flipped 180 degrees. The clamp seat 35 is connected to the flip shaft 36. The flip shaft 36 is rotatably set on the fixed bracket of the bag bin. The gear 42 is installed on the flip shaft 36. The gear 42 is engaged with the vertical rack 34. The vertical rack 34 is set to move up and down and is pushed by the rocker 23 driven by the cam 22.

[0032] like Figure 6 As shown, the clamping component 5 includes a clamping control plate 57 and a supporting roller 55. The clamping control plate 57 is arranged to move up and down and is pushed by the swing crank 51 through the push rod 56. The swing of the swing crank 51 is driven by the pull rod 58 connected to the cam mechanism. The clamping control plate 57 opens the machine clamp 15 by pushing the clamping roller 17 provided on the machine clamp. The supporting roller 55 is arranged to roll closely on the front side of the machine clamp plate 13. The supporting roller 55 is installed on the roller seat 54. The roller seat 54 is arranged to move up and down and is pushed by the swing crank 51 through the push rod 52. The roller seat 54 is guided up and down by the fixed roller frame 53.

[0033] like Figure 12-14 As shown, the movable bag opening component 7 is provided with a slide plate 71, and the slide plate 71 moves synchronously with the machine clamping plate 13 during the bag opening process. The specific structure is: a positioning pin 80 is movably provided on the slide plate 71, and a positioning pin hole 14 is provided on the machine clamping plate 13. At the starting position of the movement of the slide plate 71, a front movable push rod 81 is provided for inserting the positioning pin 80 into the positioning pin hole 14 (of course, the positioning pin can also be pushed by a cylinder), and at the end position of the movement of the slide plate 71, that is, the horizontal feeding position, a rear movable push rod is provided for withdrawing the positioning pin from the positioning pin hole. The return of the slide plate 71 after moving synchronously with the machine clamping plate 13 is pushed by the slide plate cylinder 82. When the slide plate 71 moves, the upper suction cup 76 and the lower suction cup 75 of the moving bag opening component open the bag mouth of the horizontal bag A. The moving bag opening component 7 includes upper and lower suction cups. The upper suction cup 76 is movably arranged on the slide plate 71. The end of the mounting rod 77 of the upper suction cup 76 is provided with an upper roller 79. The upper roller 79 rolls on the upper guide plate 78. The lower suction cup 75 is movably arranged on the slide plate 71. The end of the mounting rod 74 of the lower suction cup 75 is provided with a lower roller 73. The lower roller 73 rolls on the lower guide plate 72. The upper guide plate 78 and the lower guide plate 72 are fixed on the baffle plate 8 on the front side of the slide plate. The baffle plate 8 is fixedly installed on the workbench. The inner side of the baffle plate 8 is provided with a transverse slide rail 83 to guide the movement of the slide plate 71.

[0034] like Fig.15 , 16 As shown, the bag supporting component 6 includes a bag supporting frame 62 and a left bag supporting rod 68 and a right bag supporting rod 67. The left bag supporting rod 68 is connected to the left movable plate 63, and the right bag supporting rod 67 is connected to the right movable plate 66. The left and right movable plates make relative approaching and moving away movements in the bag supporting frame 62. The approaching and moving away movements of the left and right movable plates are driven by the screw nut structure 64 driven by the bag supporting motor 65. The bag supporting frame 62 is set to move forward and backward and is driven by the rocker rod 61.

[0035] The above-mentioned annular horizontal bag feeding packaging machine works as follows: the machine clamp 15 operates intermittently along the horizontal annular track. At the bag loading position, the suction nozzle 24 of the bag loading component sucks the packaging bag from the bottom of the bag bin 21 upwards, and then reaches the position of the dynamic clamp 25 and the static clamp 26 downwards. The dynamic clamp 25 closes to transfer and clamp the packaging bag A sucked by the suction nozzle 24, and the suction nozzle seat 27 drives the suction nozzle 24 to continue to move downward. The steering pin introduction groove 37 provided on the suction nozzle seat 27 hits the steering pin 38 and cannot continue to move downward. At the same time, the guide roller 40 enters the arc groove 39 from the vertical guide groove 32, so that the suction nozzle 24 is turned sideways with the suction nozzle seat 27 to make way for the position. Next, the vertical rack 34 moves downward to make the clamp seat 35 turn 180 degrees, so that the packaging bag A clamped by the dynamic clamp and the static clamp is sent to the clamping nozzle position of the left and right machine clamps 15 in a horizontal state. Let the jaws of the left and right machine clamps clamp (the jaws of the machine clamp 15 have been opened by the opening component 5 before). After the above action is completed, the horizontal bag A clamped by the machine clamp 15 leaves the upper bag position. At this time, the front movable push rod 81 moves to insert the positioning pin 80 on the slide plate 71 into the positioning pin hole 14 of the machine clamp plate 13. Therefore, in the subsequent movement of the horizontal bag A to the horizontal feeding position, the upper suction cup 76 and the lower suction cup 75 of the bag opening component move synchronously with the machine clamp 15. As the distance between the jaws of the left and right machine clamps becomes smaller, the bag mouth of the horizontal bag A is slowly opened up and down, and is fully opened when it reaches the horizontal feeding position. Then, after the bag is supported, the horizontal feeding action can be performed immediately. Finally, at the heat sealing position, the bag mouth of the horizontal bag A is heat-sealed by the heat sealing component 9, thereby realizing the efficient packaging production of double bag packaging.
